A 26-year-old patient with prior surgery for Ebstein's anomaly and a pacemaker (placed for post-surgical heart block and poor underlying rhythm) underwent SICD was placement. During defibrillation testing, device-device interaction led to undersensing of ventricular fibrillation with failure to shock. Increasing the pacemaker sensitivity resolved the problem but post shock pacing was unable to capture the heart after both shocks. The patient underwent removal of both the pacemaker and the SICD and placement of a transvenous ICD. Complex device-device interactions can occur in patients who are pacemaker dependent and undergo placement of a SICD.

The objective of this study was to determine the impact of prior arthroscopic management of glenohumeral arthritis in the young patient on results of subsequent anatomic shoulder arthroplasty. Forty-three patients that had a total shoulder or ream-and-run arthroplasty with a history of arthroscopic management were matched to 86 patients without prior surgery. Each case was matched to two cases without prior arthroscopic surgery with similar age, sex, Walch classification, and type of arthroplasty. Forty-three patients with a history of arthroscopic management were matched to 86 patients without prior surgery. The mean two year SST scores (10.3 vs. 9.9, p = 0.334), % MPI (75.4 vs. 73.0%, p = 0.687), two year SANE scores (79.6 vs. 79.8, p = 0.953), and % of patients to exceed SST score MCID (89 vs. 91%, p = 0.860) and SANE score MCID (86 vs. 75%, p = 0.180) were statistically similar in patients with prior arthroscopic debridement compared with those without prior arthroscopic debridement. The rate of MUA (9 vs. 6%, p = 0.480) and open revision (9 vs. 8%, p = 1.000) were statistically similar between groups. Arthroscopic management of glenohumeral arthritis in patients aged 65 years and younger prior to anatomic shoulder arthroplasty was not associated with inferior outcomes for either total shoulder arthroplasty or ream-and-run arthroplasty.

Purpose Characterize the clinical outcomes of endometrial cancer vaginal recurrences after previous surgery and radiation therapy treated with reirradiation including image-guided interstitial high-dose-rate (HDR) brachytherapy. Methods and materials A single-institution retrospective study identifying women receiving reirradiation for vaginal recurrence of endometrial cancer between 2004 and 2017. Results Twenty-three women had vaginal recurrences of endometrial cancer, median 13.7 months (range 3.5–104.9) from initial radiation. All received reirradiation with interstitial HDR brachytherapy, and seven also received external beam radiation. Median reirradiation EQD2_10 was 48 Gy (range 24.0–68.81), and median cumulative EQD2_10 was 106.25 Gy (range 62.26–122.0). Median follow-up after reirradiation was 40.2 months (range 4.5–112.7). At 3 years, overall survival was 56%, cancer-specific survival was 61%, and disease-free survival was 46%. 14 patients experienced disease recurrence; 10 including distant sites, one at a regional node only. Three patients experienced local recurrences, two of whom did not complete the prescribed course of reirradiation. The overall crude local control rate was 87%. Three patients experienced Grade 3 vaginal toxicity. There was no bladder or rectal toxicity with Grade >2. Conclusions Reirradiation including interstitial HDR brachytherapy is a promising option for vaginal recurrences of endometrial cancer after prior radiation, with high rate of local control and acceptable toxicity. However, distant failure is common. Further studies are needed to determine cumulative radiation dose limits and the role of systemic therapy in this scenario.

This article will focus on the common failures and the treatment plans for complications after flatfoot deformity correction procedures including how to prevent the failures. The comprehensive history and the physical examination, including a thorough assessment of which procedure was used throughout the prior surgery, are essential to realize this complex problem. The appropriate surgical procedure should be adjusted to the symptoms as it may be related to the cause of the failures from the previous operation.

BACKGROUND Prior knee surgery before total knee arthroplasty (TKA) puts patients at higher risk of inferior outcomes and increased care cost. This study compares intraoperative and postoperative variables including procedure duration, components, length of stay, readmission, complications, and reoperations among patients undergoing conversion TKA. METHODS Primary TKA from a single-surgeon database identified 130 patients with prior knee surgery to form a "conversion" cohort. One-to-one matching identified 130 patients of similar age, American Society of Anesthesiologists score, body mass index, and gender without prior knee surgery for comparison. Perioperative and 90-day postoperative variables were compared between patients with and without prior surgery, within the conversion group based on the type of prior surgery, and whether the prior surgery was bony or soft tissue. RESULTS The conversion group had longer mean operative time (96.1 vs 90.0 minutes, P = .01), higher revision component utilization (8.5% vs 0.8%, P = .005), and higher calculated blood loss (1440 vs 1249 mL, P = .004). Thirty-eight patients with prior fracture or osteotomy were compared to the remaining 92 patients in the conversion group and showed longer operative time (107.1 vs 91.3 minutes, P < .001), higher 90-day readmissions (18.4% vs 3.3%, P = .003), more complications (23.7% vs 8.7%, P = .021), and greater utilization of revision components (26.3% vs 1.1%, P < .001). CONCLUSION Patients undergoing conversion TKA required increased resource utilization, particularly patients with a prior osteotomy or fracture. Policymakers should consider these variables, as they did in conversion THA, in adding a code to account for increased case complexity and resource utilization.

The aim of this study is to assess the benefits of a nurse-led home injection service for somatuline autogel-treated patients with acromegaly, including the adherence to treatment and disease control. Historical prospective data of all patients with acromegaly initiating somatuline autogel between November 14, 2000, and March 9, 2020, who voluntarily enrolled in the nurse-led home injection service between January 1, 2018 and June 30, 2020. Adherence to treatment was calculated as the number of administered injections divided by the number of expected injections during the follow-up period. Excellent adherence to treatment was defined when >90% of scheduled injections were administered, while low adherence was defined when patients received

Objective Saddle nose deformity is a well‐described condition that most commonly results from trauma or prior surgery. For larger saddle nose deformity defects, bone grafts are a reconstructive option that provide adequate structure for repair. One new technique for repair of these deformities is a vomerian bone onlay graft. We aim to provide a review of literature on autogenous repair of saddle nose deformities, as well as introduce a new technique in which the vomer bone is used as an onlay bone graft. Methods Literature review and case series. Five cases in which vomer onlay grafts were used for repair of saddle nose deformity were reviewed between January 2013 and December 2015. Aesthetic outcomes and postoperative complications were evaluated at subsequent follow‐up visits in clinic. Results In all cases where vomer bone was harvested, the vomer onlay graft provided adequate structure to traverse the saddle nose deformity. No postoperative complications were observed in an 18 month follow‐up period. Conclusion Vomerian bone onlay grafts are a reconstructive option for saddle nose deformity and nasal dorsum defects. While septal cartilage is commonly used, and ethmoidal bone has been previously described as an option for composite graft reconstruction, vomer bone onlay grafting has not been well described in the literature. This method may be of use when previous nasal surgery has been performed and standard septal cartilage is not possible to harvest. The aesthetic outcomes following nasal dorsum reconstruction using onlay grafts are favorable, but long‐term outcomes of these grafts require further study. Level of Evidence IV., Vomerian bone onlay grafts are a reconstructive option for saddle nose deformity and nasal dorsum defects. While septal cartilage is commonly used, and ethmoidal bone has been previously described as an option for composite graft reconstruction, vomer bone onlay grafting has not been well described in the literature. The aesthetic outcomes following nasal dorsum reconstruction using onlay grafts are favorable, but long‐term outcomes of these grafts require further study.

Perforator-based flaps have in recent years become the mainstay of autologous breast reconstruction practice. Imaging modalities ranging from Doppler ultrasound to CT angiography demonstrate varying utility in the preoperative identification and localisation of perforators. Despite these available radiological investigations, finding and quantitatively assessing perforators remain a time-consuming and tedious process that is often complicated by a number of factors including variable anatomy prior surgery and body habitus. Thermographic imaging shows promise as a novel modality for preoperative localisation of perforator vessels. This review summarises the currently available evidence for its application in perforator mapping for abdominal-based autologous breast reconstruction. We discuss the development of the technology over the years, its current use, its advantages and how it may impact on reconstructive breast surgery.

Adhesive small bowel obstruction (ASBO) is commonly caused by intra-abdominal adhesions, usually from prior surgery. Conservative management is the mainstay of treatment, with adhesiolysis required for non-resolving obstruction. An unusual patient presentation of ASBO is presented here, where the cause is proposed as an automatic implantable cardioverter defibrillator (AICD) within the abdomen. Although the patient had several presentations of ASBO successfully treated with conservative management, a non-resolving obstruction required surgical management. At laparotomy, the AICD was found to be in close association with extensive matted adhesions to adjacent small bowel. Adhesiolysis was performed, with the AICD implanted in a subrectus pocket. The patient had an uncomplicated recovery, and at review 6 weeks following the operation was found to have a normal bowel habit with nil further episodes concerning for obstruction. This case highlights the importance of non-classical risk factors being a possible cause of ASBO.

Introduction Cranioplasty (CP) is a multifaceted procedure in a heterogenous patient population, with a high risk for complication. However, no previous large-scale studies have compared outcomes in primary (ie, first attempt) CP versus revision CP (ie, following previous attempts). The authors, therefore, analyzed long-term outcomes of 506 consecutive primary and revision CPs, performed by a single surgeon. Methods All CPs performed between 2012 and 2019 were analyzed under IRB protocol approval. Surgeries were categorized as either primary (no previous CP; n = 279) or revision CP (at least one previous CP; n = 227). Complications were defined as either major or minor. Subgroup analyses investigated whether or not CP complication risk directly correlated with the number of previous neuro-cranial surgeries and/or CP attempts. Results The primary CP group experienced a major complication rate of 9% (26/279). In comparison, the revision CP group demonstrated a major complication rate of 32% (73/227). For the revision CP group, the rate of major complications rose with each additional surgery, from 4% (1 prior surgery) to 17% (2 prior surgeries) to 39% (3-4 prior surgeries) to 47% (≥5 prior surgeries). Conclusion In a review of 506 consecutive cases, patients undergoing revision CP had a 3-fold increase in incidence of major complications, as compared to those undergoing primary CP. These results provide critical insight into overall CP risk stratification and may guide preoperative risk-benefit discussions. Furthermore, these findings may support a center-of-excellence care model, particularly for those patients with a history of previous neuro-cranial surgeries and/or CP attempts.

AIM: To review the outcome for primary or revisional external dacryocystorhinostomy in patients with granulomatous polyangiitis. PATIENTS AND METHODS: Retrospective case-note review to include age at presentation, duration of prior GPA, immunosuppression at time of surgery, nature of first lacrimal surgery, and symptomatic control. RESULTS: Forty-eight patients (25 female; 52%) presented at an average age of 50.5 years and 7 (15%) had prior lacrimal surgery on one (5/7; 71%) or both sides. The duration of systemic GPA varied, with 40% having disease for up to 3 years prior to lacrimal referral, and 41/48 (85%) being on systemic immunosuppression. Forty-eight patients had 71 affected drainage pathways—having symptoms for an average of 22 months (range

Ectopic pregnancy is a serious diagnosis occurring in 1-2% of all pregnancies, causing significant morbidity and mortality if unrecognized. Management of ruptured ectopic pregnancy typically includes salpingectomy, which decreases the risk for repeat ectopic pregnancies. In rare cases after salpingectomy, non-viable implantation may occur on the ipsilateral side of prior surgery. We present a patient with a cornual pregnancy on the ipsilateral side of her prior ectopic pregnancy and salpingectomy.

Background We hypothesize that revision surgery that includes soft tissue releases for patients with residual pain and reduced range of motion following rotator cuff repair can provide pain relief and improvement of motion and function. Methods Patients were identified via a retrospective chart over a 10-year period who had a history of previous rotator cuff repair and had revision surgery with or without a rotator cuff repair and soft tissue release. Changes in visual analog scores (VAS) pain score on a 10-point scale and shoulder motion including forward flexion and external rotation were evaluated from the preoperative visit to the postoperative visit. Results In total, 73 patients underwent procedures to address their symptoms following failed rotator cuff repair. Patients that underwent soft tissue release with revision rotator cuff repair and those who underwent isolated soft tissue release had decreased postoperative VAS pain scores (absolute reduction of 3 and 1.6 points, respectively) and improved postoperative forward flexion (15.3° and 13.6° respectively). Patients that have had one previous surgery had decreased pain (absolute reduction of 3.2 points), increased forward flexion and external rotation (16.2° and 4.9°). Patients that underwent two or more previous surgeries had decreased pain (absolute reduction of 1.8 points) and increased forward flexion (12.7°). Patients who were filing a Worker’s compensation claim also had decreased pain (absolute reduction of 2.2 points) and increased forward flexion (14.9°). Overall, there was a VAS pain scores absolute reduction of 2.6 points or 49.5% when examining the entire patient population. Conclusion Operative management by performing soft tissue release with or without concurrent revision rotator cuff repair is successful for both decreasing pain as well as improving motion. This effect was noted both in patients with commercial insurance and worker’s compensation claims. Improvements of pain and motion were more significant in patients who had undergone one prior surgery compared to those who have had multiple prior procedures.

Background During the course of inflammatory bowel disease (IBD), approximately 20% of patients with ulcerative colitis (UC) and 80% of Crohn’s disease (CD) patients will require surgery. The most common operation is total proctocolectomy and ileoanal pouch anastomosis (IPAA) for UC patients and ileocecal (IC) resection for CD. In pregnant IBD patients, guidelines name the presence of IPAA as a relative indication for Cesarean section (C-section). The effect of prior IBD-related surgery on mode of delivery and pregnancy-related outcomes remains unknown. Aims To describe pregnancy-related outcomes in pregnant women with IBD who have undergone prior IBD-related surgery. Methods We performed a retrospective cohort study of pregnant women with IBD including those with prior IBD-related surgeries including IPAA, IC resection, total or partial colectomy and ileostomy formation who delivered an infant at our medical center from 2016 to 2020. We assessed the mode of delivery, delivery characteristics (emergency vs. planned C-section) and maternal and neonatal outcomes Results Fifty-six UC patients and 64 CD patients were included in the analysis, of which 10 and 24 had undergone prior IBD-related surgery, respectively. The mean age at conception was 34.10 years in the surgical UC group and 30.30 years in the surgical CD group. Mode of delivery: C-section rates were higher in post-surgical compared to non-surgical UC patients (70% vs. 30.4%, p = 0.02). Similar numbers of C-sections were performed emergently in the surgical compared to non-surgical UC group (10% vs. 18%, p = 0.53). Comparatively, there was no significant difference in C-section rates in post -surgical compared to non-surgical CD mothers (50% vs. 40%, p = 0.44), with 13% performed emergently in both groups. Maternal outcomes: Gestational diabetes developed in 10% of surgical UC and 4.5% of surgical CD patients. Premature rupture of membranes developed in 10% of surgical UC and 9.1% of surgical CD patients. There was no difference in pre-eclampsia rates in the surgical and non-surgical CD groups (9.1% vs 13.2%, p = 0.64). Neonatal outcomes: There was no significant difference in pre-term birth rates in post-surgical compared to non-surgical UC mothers (10% vs. 15.2%, p = 0.67) or in surgical compared to non-surgical CD mothers (13.6% vs. 5.1%, p = 0.29). Neonatal Intensive Care Unit (NICU) requirements were higher in infants born to post-surgical CD compared to non-surgical CD mothers (18.2% vs. 2.7%, p = 0.04). More low birth weight (LBW) infants were born to post-surgical CD vs non-surgical CD mothers (13.6% vs. 0%, p = 0.02). Conclusions Women with IBD who have had prior IBD-related surgery may be at increased risk of developing adverse gestational and neonatal outcomes. Women with surgical UC have an increased incidence of Cesarean delivery. Funding Agencies None

BACKGROUND: Although bariatric surgery (BS) has an excellent safety profile, postoperative complications have undoubtedly increased due to the rise in the amount of operations performed annually. In parallel, the number of visits to the Emergency Department (ED) after surgery is increasing. The aim of this study was to describe the frequency, and the risk factors associated with postoperative ED visits after BS. METHODS: This study included patients who had undergone different types of BS procedures between June 2016 and December 2019. Patients’ prior surgery types, ED visiting timings, main complaints, symptoms and the diagnoses they received, readmissions, and the interventions they had were noted and compared. RESULTS: A total of 408 patients operated on using either the robotic or laparoscopic method due to morbid obesity, including 91 (22.3%) SG, 231 (56.6%) OAGB, 62 (15.2%) SADS-p, and 24 (5.8%) RS, were included into the study. During follow-up, fifty-three of the 408 patients applied to the Emergency Department 62 times with different complaints. ED admission rates in the OAGB group were significantly higher (P=0.04). While the most common complaint seen in the patients admitted to the ED after BS was localized abdominal pain with 25.8%, the most common diagnosis of the patients was cholelithiasis with a rate of 16.1%. CONCLUSIONS: ED visits after BS usually continue intensively during the first year. Most of these applications can be prevented with regular outpatient follow-ups. Some of these require life-saving surgery in emergency conditions and do not allow the patient to be transferred to a bariatric center. WOS:000643095400009 33754589

Background: The aim of this study was to evaluate the influence of prior abdominal surgery on perioperative outcomes in patients who underwent robot-assisted partial nephrectomy.Methods: We reviewed patients with small renal tumors who underwent robot-assisted partial nephrectomy from October 2011 to September 2020 at our institution. Comparisons between patients with prior abdominal surgery and with no prior abdominal surgery were based on perioperative outcomes. Furthermore, patients underwent transperitoneal robot-assisted partial nephrectomy was compared between those with and without prior abdominal surgery. The Mann–Whitney U test and the chi-square test were used for statistical analyses of variables. Results: Of 156 patients who underwent robot-assisted partial nephrectomy, 90 (58 %) had no prior abdominal surgery, whereas 66 patients (42 %) underwent prior abdominal surgery. No significant differences in perioperative outcomes were observed between with and without prior abdominal surgery groups. In transperitoneal approach robot-assisted partial nephrectomy, 31 patients (38.8 %) had prior abdominal surgery, whereas 49 patients had no prior abdominal surgery. Trocar insertion time in the with prior abdominal surgery group took longer than the without prior abdominal surgery group (32 vs. 28.5 min, p = 0.031). The other perioperative outcomes were no significant differences. In the conversion rate, no significant difference was observed between the two groups (p = 0.556).Conclusions: Prior abdominal surgery does not appear to affect Robot-assisted partial nephrectomy. Robot-assisted partial nephrectomy can be a safe procedure for patients with prior abdominal surgery. In transperitoneal approach robot-assisted partial nephrectomy with prior abdominal surgery, trocar insertion time was longer, but no significant differences were found in other outcomes. The conversions to radical nephrectomy and open partial nephrectomy were not associated with prior abdominal surgery. Transperitoneal approach robot-assisted partial nephrectomy is thus considered a safe procedure for patients with prior abdominal surgery.

A 49-year-old man presented to the nearest emergency department profoundly septic with significantly raised inflammatory markers. He had a background of floor of mouth invasive squamous cell carcinoma for which he underwent complex head and neck surgery followed by adjuvant radiotherapy and insertion of a percutaneous gastrostomy tube for feeding. He experienced 3 weeks of retching, cough and malaise. Imaging revealed both an oesophageal perforation and perforated duodenal ulcer, presumed secondary to oesophageal stricturing from his prior surgery and radiotherapy.

Younger patients with severe glenohumeral (GH) arthritis are a challenge to treat, as they have high physical demands, high expectations, a long lifespan, and often altered anatomy from prior surgery or congenital deformity. Nonoperative management is the cornerstone of treatment; however, when it fails, shoulder arthroplasty can be indicated. Although the literature suggests that total shoulder arthroplasty is the most appropriate for severe GH arthritis, there are a subset of patients in which a hemiarthroplasty can still be successful. This article reviews the clinical performance of hemiarthroplasty in patients with specific diagnoses while highlighting the limitations of the operation.

Background: The alarming increase in caesarean section rates worldwide has led to a shift of focus to caesarean section rates and indications for caesarean section. The main objective of the study was to analyse the indications for caesarean section with the aim of finding viable interventions which could help decrease the caesarean rates. Methods: A retrospective study from 1st January 2017 to 31st December 2017 was conducted in which we analysed patient records of those delivering in unit III of our institute. Analysis of patient records was done and indication for caesarean was analysed. Results: A total of 496 women delivered in our unit in 2017, of these, 303 (61.09%) had a vaginal delivery and 193 (38.91%) had caesarean section. 108 patients (21.77%) had a history of at least one previous caesarean section and of these 94 (87.03%) underwent a repeat caesarean section. The primary caesarean section rate was 25.51%. Section was done for breech presentation in eleven primigravidae (5.7% of sections) and in fifteen multigravidae (7.77% of sections) including those with a previous section. Four patients had multiple pregnancy (2.04% of all sections). Eleven patients had a preterm section (5.7% of sections). Conclusion: In order to decrease caesarean rates the group that requires most focus is those in whom a primary section is being done. Few patients who have undergone at least one prior surgery are willing to take the risk inherent to a trial of labour (TOLAC). Classification and reporting of caesarean section according to the Robson ten point criteria will help in a better understanding of the indication, comparison and auditing and help to establish guidelines that can help decrease the caesarean rates.

Purpose To determine return to play (RTP) rates after biceps tenodesis (BT) in professional baseball players. Methods Major League Baseball has maintained a prospective database containing all major and minor league baseball players who have undergone shoulder surgery since 2010. All players who had undergone BT were included. Minimum follow-up was 24 months, and thus we included data from 2010 to 2013. Using this database we determined the incidence, demographics, prior surgery history, concomitant procedures, RTP rates, and time to RTP. Results Between 2010 and 2013, 17 professional baseball players underwent BT. Seventy-one percent of the 17 were pitchers, and 29% of the 17 were in the major league. Forty-seven percent of the 17 had a history of a prior shoulder surgery and 47% of the 17 underwent concomitant labral repair. For all players, RTP after BT was 35%, whereas RTP after BT without a concomitant reconstructive procedure was 44% in 10 ± 6 months, and 25% for those who underwent both BT and a concomitant reconstructive procedure ( P = .620). All players who RTP were able to return to at least 20 games at their preoperative level of play. Return to professional play was 80% among position players and 17% among pitchers ( P = .028). For those pitchers who RTP, performance was not statistically changed. Conclusions Professional baseball players who undergo BT have a 35% rate of return to their prior level of play. Whereas pitchers have only a 17% rate of RTP, position players have an 80% rate of RTP. Of those who returned, all returned to their prior level of play. The pitchers who returned had no significant change in performance statistics. Level of Evidence Level IV, therapeutic study, a case series.

Methods: A prospective observational cohort study was conducted among 212 consecutive patients who underwent oculoplastic surgery performed under general anesthesia. The patients were assessed according to quantified levels of pain and discomfort postoperatively. Analgesic requests were recorded, and responses were statistically analyzed. Results: Pain and discomfort after oculoplastic surgery under general anesthesia were reported by 32.1% and 28.3% of the patients, respectively; 2.8% of the patients requested analgesic medication within 18 hours after surgery. The patients who underwent orbital decompression, secondary orbital implantation, and orbital fracture repair were more likely to develop significant postoperative pain and discomfort (P

Summary Objectives Primary female epispadias encompasses a spectrum of disease, presenting with a variable degree of incontinence. We hypothesized that although perineal urethrocervicoplasty can be a successful first-line procedure in patients with normal bladder, a more radical reconstruction was necessary to achieve continence in cases lying at the most severe end of the spectrum. Our aim was to assess the results of a surgical management using perineal approach in girls with normal bladder capacity, and Kelly radical soft-tissue mobilization (RSTM) in patients with inadequate bladder, based on the assumption that bladder capacity (BC) is a reliable marker of epispadias severity. Study design Prospective inclusion of incontinent girls with female epispadias referred to a single institution. Patients with normal BC were treated with perineal urethrocervicoplasty (PUCP, group 1). Patients with small bladder underwent RSTM (group 2). Follow-up was at 1, 3, 6, and 12 months postoperatively, then annually, including physical examination, renal ultrasound at each visit, continence status, and estimation of functional/maximal BC. The main study outcome was continence status at the age of 5 years or later, if postoperative follow-up was >12 months. Results From 2006 to 2017, 16 consecutive children were prospectively included in this study, at a median age of 39 months (5–102 months). Seven girls were included in group 1 and underwent PUCP; at the last follow-up, five out of seven were dry by day (4/5 day and night), although three out of five required bladder-neck injection after perineal reconstruction due to stress incontinence. Two patients with persistent incontinence and absence of BC increase after PUCP subsequently underwent RSTM. Eleven patients with low BC (56% [10–94%] of expected BC) were included in group 2 (9 without prior surgery, 2 after PUCP failure). Among the eight evaluable patients, eight out of eight achieved diurnal continence, and 3/8 were fully continent. One girl with obstructive micturition required clean intermittent catheterization. Discussion The traditional approach of female epispadias based on staged reconstruction (urethroplasty followed by bladder-neck reconstruction) raised concerns regarding the risk of non-physiological obstructive micturition. The perineal approach was suggested as an alternative, with reported diurnal continence rates of 60–80%, but less than 50% of nocturnal continence, presumably in relation with limited bladder capacity. In cases selected within the most severe end of the epispadias spectrum, the Kelly RSTM seems to offer excellent continence rates. Conclusion A tailored approach to female epispadias, based on perineal reconstruction in favorable cases, and radical soft-tissue mobilization in severe cases, seems to yield good continence outcomes in the long term.

AIM: To evaluate the efficacy of selective laser trabeculoplasty (SLT) in glaucomatous eyes with previous incisional glaucoma surgery. METHODS: A retrospective cohort of eyes that underwent SLT at a single institution from 2013-2015 were followed for 1y. Reduction in intraocular pressure (IOP) following SLT was evaluated in eyes with prior trabeculectomy with ExPress mini shunt (Alcon, Ft Worth, TX, USA), Ahmed valve (New World Medical, Cucamonga, CA, USA), or combined phacoemulsification-trabeculectomy. A control group was included with eyes without prior surgery that underwent SLT. Success was defined as >20% drop in IOP from pre-SLT baseline. RESULTS: One-hundred and six eyes were included with 53 in both the prior glaucoma surgery (PGS) and no prior glaucoma surgery (NPGS) groups. Mean pre-SLT IOP was 19.2±4.3 and 20.6±6.0 mm Hg for PGS and NPGS groups, respectively (P=0.17). Both groups produced statistically significant IOP reductions at 1 and 6mo (P

The loss of knee extension, even if minimal, is disabling and considerably affects the individual's quality of life. This loss of extension can be a consequence of prior surgery, including a previous anterior cruciate ligament reconstruction. Although this loss of extension may be treated through an isolated arthroscopic procedure, a more severe case may warrant an invasive approach. In these cases, a posterior capsulotomy of the knee may be done if all conservative measures have been exhausted. This procedure has been proven to be safe and effective in the re-establishment of full extension in the setting of a minor flexion contracture of the knee. The purpose of this Technical Note was to describe our preferred technique when performing an open posterior capsulotomy of the knee for the treatment of minimal extension deficit.

Purpose Prior studies suggest a high incidence of leptomeningeal failure (LMF) in breast cancer metastatic to brain. This study examines breast cancer-specific variables affecting development of LMF and survival after Gamma-Knife Radiosurgery (GKS). Methods Between 2000–2010, 149 (breast) and 658 other-histology patients were treated with GKS. Hormone/HER2, age, local/distant brain failure, prior craniotomy, and prior whole-brain radiotherapy (WBRT) were assessed. Median follow-up was 54 months (range, 0–106). Serial MRI determined local and distant-brain failure and LMF. Statistical analysis with categorical/continuous data comparisons were done with Fisher’s-exact, Wilcoxon rank-sum, log-rank tests, and Cox-Proportional Hazard models. Results Of 149 patients, 21 (14%) developed LMF (median time of 11.9 months). None of the following predicted for LMF: Her2-status (HR = 0.49, p = 0.16), hormone-receptor status (HR = 1.15, p = 0.79), prior craniotomy (HR = 1.58, p = 0.42), prior WBRT (HR = 1.36, p = 0.55). Non-significant factors between patients that did (n = 21) and did not (n = 106) develop LMF included neurologic death (p = 0.34) and median survival (8.6 vs 14.2 months, respectively). Breast patients who had distant-failure after GKS (65/149; 43.6%) were more likely to later develop LMF (HR 4.2, p = 0.005); including 15/65 (23%) patients who had distant-failure and developed LMF. Median time-to-death for patients experiencing LMF was 6.1 months (IQR 3.4–7.8) from onset of LMF. Median survival from LMF to death was much longer in breast (6.1 months) than in other (1.7 months) histologies Conclusion Breast cancer patients had a longer survival after diagnosis of LMF versus other histologies. Neither ER/PR/HER2 status, nor prior surgery or prior WBRT predicted for development of LMF in breast patients.

Surgeons are increasingly being faced with the challenge of treating elderly patients with colon cancer. The present study therefore aimed to compare the short-term outcomes of single-port laparoscopic surgery (SILS) for elderly patients with colon cancer (≥70 years) with those in younger patients (41–69 years; control group). Among 100 patients with colorectal cancer who had been treated with single-port laparoscopic surgery between January 2011 and December 2014, 56 (56.0%) were ≥70 years of age. The results of treatment and short-term outcomes in the elderly group (n=56) were retrospectively compared with the younger patients in the control group (n=44). The sex distribution, body mass index, history of prior surgery and the American Society of Anesthesiologists physical status classification were similar between the groups. Onodera's prognostic nutritional index demonstrated significant differences between the elderly and control groups (38.3 vs. 49.8; P

Objectives To identify subgroups of patients with lung cancer receiving chemotherapy based on the severity dimension of symptom experience, and to examine changes in membership between these subgroups over time. Methods Patients who were scheduled to receive chemotherapy completed the Chinese version of the MD Anderson Symptom Inventory and the revised lung cancer module with a total of 19 symptom items. Data were collected at three time points: two weeks before chemotherapy (T1), after chemotherapy cycle 1 (T2), and after chemotherapy cycle 3 or above (T3). The latent profile analysis and latent transition analysis were used to identify underlying subgroups and describe changes in subgroup membership over time. Results From the total sample (N = 195), 160 patients completed the symptom assessment at T1, T2, and T3. Two distinct latent symptom profiles of patients could be identified at T1, T2, and T3, which were classified as "Mild" and "Moderate-Severe" profiles. From T1 to T2 and T3, members in the Mild profile were more likely to move to the Moderate-Severe profile. Chemotherapy protocols, prior surgery treatment, and level of education can predict the transitions. Conclusion Results provide a better understanding of the patient's different symptom experiences and characteristics. These could help clinicians to anticipate symptom patterns and develop interventions in lung cancer patients who were scheduled to receive chemotherapy for the first time.

The patellofemoral joint is often affected by torsionaldisorders of the lower limb, causing pain, instability and knee degeneration. The aims of this study were to determine functional outcomes of patients who underwent a high tibial derotation osteotomy (HTDO) for symptomatic squinting patella due to increased external tibial torsion. Moreover, factors associated with inferior clinical outcomes were investigated.Patients with symptomatic squinting patella, increased external tibial torsion (30°) treated with this technique, and with 2 years of follow up were included. Fulkerson and Kujala patellofemoral joint scores were assessed. Age, body mass index, history of prior surgery, increased femoral anteversion, association of lateral retinaculum release and patellar cartilage lesions were analysed.Sixty HTDOs were included in this retrospective study with an average of 66 months of follow up. The mean Kujala score improved from 47.5 preoperatively to 93 postoperatively. The mean Fulkerson score improved from 40.6 to 91.6. Kujala subscores for pain improved from 8.6 to 30.4, for instability improved from 6.4 to 17.9, and their ability to climb stairs increased from 6.9 to 17.9 (all P 0.0001). Multivariate logistic regression model identified that patient age (P 0.005) and advanced chondral damage (P 0.001) were the dominant factors predicting inferior clinical outcomes using Kujala's score.HTDO provided good results regarding the pain symptoms, instability and the ability to climb stairs. Advanced chondral damage and advanced age had negative effects on outcomes.

Dermatosis neglecta or dermatitis neglecta is a condition which occurs due to inadequate cleansing of a localised area of skin resulting in the accumulation of dirt, sebum, sweat, corneocytes and bacteria. These patients do not clean the area due to various reasons like pain at the site, prior surgery, physical disability, neurological deficit, or psychiatric illness. Vigorous rubbing of the lesion with alcohol soaked gauze results in removal of the lesion. We report a case of dermatosis neglecta in a 50 year old lady with carcinoma breast following mastectomy on the right side. She did not clean the area adequately as she was scared that the area of suture after mastectomy would give way, thus resulting in hyperkeratotic lesions.

Microvascular free tissue transfer has revolutionized reconstruction and subsequently functional outcomes in the head and neck, but requires suitable recipient vessels for successful results. Recipient vessels can be significantly compromised by prior surgery, radiation therapy, or existing and/or underlying vascular disease in the neck. When further microvascular reconstruction is required in the vessel-depleted neck, identification of appropriate vessels for anastomosis can be difficult and can present complex decisions for the surgeon as well as the patient. In this article, we review the available literature on the vessel depleted neck and the possible vessel options. We present critical strategies for preoperative treatment planning and vessel selection in these patients. We also discuss the benefits and limitations of arterial and venous options while commenting on our unique institution's experiences. The external carotid branches as well as the available subclavian artery branches are presented in detail. The venous anatomy is also described, with particular focus on the accompanying veins and cephalic vein. We provide guidance on the selection and modification of free flaps to achieve the greatest function and cosmetic outcomes in the vessel depleted neck. Our collection of advanced management techniques will provide surgeons with more options to manage the complexity of the vessel depleted neck, and to further help patients understand the risk and benefits of these selections.

Background This study compares outcomes of reverse total shoulder arthroplasty (RTSA) in patients with prior rotator cuff repair to matched control patients without prior surgery. Patients and methods All primary RTSAs with prior surgery were retrospectively identified from a prospective research database between 2000 and 2014. RTSA patients with prior open or arthroscopic rotator cuff repair and minimum 2-year follow-up, with age- and sex-matched controls, were identified. Active range of motion (ROM) and functional outcomes were evaluated. Preoperative, postoperative and improvement in outcomes were compared between groups. Results One hundred fifty RTSA patients were included, with 75 patients in each group (42 female, 33 male). Mean age of the RTSA group with prior rotator cuff repair was 69.6 years (average follow-up, 3.8 years) compared to the RTSA group without prior surgery (control) aged 70.0 years (average follow-up, 3.3 years). Preoperatively and postoperatively, RTSA patients with prior cuff repair had slightly worse overhead ROM and outcome scores compared to controls but none were statistically different. The RTSA and control groups had similar and significant improvements in all postoperative ROM and outcome scores. Complications were similar between groups. Discussion RTSA patients with prior rotator cuff repair had similar ROM, functional outcome scores, and complications compared to a matched control group without prior surgery. Level of Evidence III, Treatment Study.

Background Few studies have focused on shoulder arthroplasty after anterior stabilization procedures. This study compares the outcomes of total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA) after anterior stabilization surgical procedures. Methods All primary shoulder arthroplasties from 2000 to 2014 with prior surgery were retrospectively reviewed from a prospective research database. The inclusion criteria were primary TSA or RTSA, a history of anterior stabilization surgery, and minimum 2-year follow-up. Soft-tissue and bony anterior stabilization procedures were included. We compared the following between TSA and RTSA patients: active range of motion (ROM) and Shoulder Pain and Disability Index 130; Simple Shoulder Test; American Shoulder and Elbow Surgeons (ASES); Short Form 12; University of California, Los Angeles; and Constant scores. The RTSA group was also compared with an RTSA control group. Results The study included 15 TSA and 10 RTSA patients with average follow-up periods of 3.3 and 4.0 years, respectively. RTSA patients experienced greater improvements in all ROMs except internal rotation; these were not statistically significant despite the mean values for RTSA being above the minimal clinically important difference compared with TSA for forward flexion and abduction. RTSA patients had better improvements in all functional outcomes; only the ASES score was statistically significant. TSA patients had a 33% complication rate and a 20% reoperation rate. RTSA patients had no complications or reoperations. The group that underwent RTSA with prior anterior stabilization surgery had similar improvements in ROM and outcome measures to the RTSA control group. Conclusion RTSA patients had better postoperative improvement in most ROMs and all functional scores; only the ASES score was statistically significant. This study suggests better outcomes with a lower complication rate with RTSA after prior anterior stabilization procedures compared with TSA.

Outcomes of shoulder surgery in workers' compensation (WC) patients have generally been inferior to those in non-WC patients. The purpose of this study was to compare the complication rates and clinical outcomes after shoulder arthroplasty in WC patients and control non-WC patients.An institutional shoulder arthroplasty database was queried for patients with minimum 2-year follow-up who underwent total shoulder arthroplasty, reverse total shoulder arthroplasty, or hemiarthroplasty. WC patients were age and sex matched with non-WC patients and retrospectively evaluated for complication rates, patient-reported outcome (PRO) scores, and range of motion.We matched 45 WC and 45 non-WC patients by age and sex, with the WC group having a higher rate of prior surgery (82% vs 38%, P .001). Both groups experienced significant improvements in all PROs, forward elevation, and external rotation (P .05 for all). The WC group had inferior 2-year outcomes for all PROs and forward elevation (P ≤ .001 for all), as well as a higher reoperation rate (16% vs 2%, P = .030) and higher rate of persistent pain at final follow-up (33% vs 11%, P = .021). On multivariate regression controlling for other variables including number of prior surgical procedures, WC status remained associated with lower improvements in American Shoulder and Elbow Surgeons (P .001), functional (P .001), and Simple Shoulder Test (P .001) scores, as well as a higher reoperation rate (P = .015) and higher rate of persistent pain (P = .027).Although both WC and non-WC patients experienced significant clinical improvements after shoulder arthroplasty, WC patients had a higher reoperation rate, inferior PROs, and a higher rate of persistent pain.

Background: The purpose of this study was to prospectively evaluate and compare the long-term clinical and radiographic outcomes of using osteochondral autograft and allograft to manage either recurrent or large osteochondral lesions of the talar dome (OLT) in a single surgeon’s practice. Methods: Between January 2008 and January 2014, a total of 40 patients presented with either a recurrent OLT that failed initial arthroscopic treatment (ie, excision, curettage, debridement, and micro-fracture) or a primary OLT greater than 1.5 cm2 that had undergone no prior surgery. Before surgery, 20 patients were randomized to receive osteochondral autograft plugs (Arthrex, Naples, FL) from the ipsilateral superolateral distal femoral condyle whereas the remaining 20 were randomized to receive osteochondral allograft plugs from a fresh size-matched donor talus (Joint Restoration Foundation, Centennial, CO, and Arthrex, Naples, FL), but 4 of these were excluded that received a hemi-talus allograft with internal fixation. Preoperative and postoperative function and pain was graded using the Foot and Ankle Ability Measures (FAAM) scoring system and a Visual Analog Scale (VAS) of pain, respectively. Radiographs were assessed for osteochondral graft healing, joint congruency, and degenerative changes. Data regarding postoperative complications and revision surgeries were also recorded. Results: Of the 20 patients who received osteochondral autograft, the mean FAAM score increased from 54.4 preoperatively to 85.5 at the time of final follow-up. The mean VAS pain score decreased from 7.9 of 10 preoperatively to 2.2 of 10 at final follow-up. Two patients (10%) that received osteochondral autograft, 1 for a recurrent OLT of 1.3 cm2 and 1 for a primary OLT of 2.0 cm2, developed a symptomatic nonunion at the entire graft site. Both of these patients had their autograft converted to talar allograft plugs and achieved full osteochondral healing. At the time of final follow-up, no patients who received osteochondral autograft developed ankle degenerative changes or knee complications. The mean FAAM score of the 16 patients who received osteochondral allograft plugs increased from 55.2 preoperatively to 80.7 at the time of final follow-up. This postoperative score was lower than that of the osteochondral autograft group, but not to a statistically significant degree ( P = .25). The mean VAS pain score decreased from 7.8 of 10 preoperatively to 2.7 of 10 at final follow-up. This postoperative score was higher than that of the osteochondral autograft group but not to a statistically significant degree ( P = .15). Three patients (18.8%) that received osteochondral talar allograft, 2 for recurrent OLTs less than 1.5 cm2 and 1 for a primary OLT of 2.2 cm2, developed a symptomatic nonunion at the entire graft site. Two of these 3 patients had their allograft converted to osteochondral autograft plugs harvested from the ipsilateral superolateral distal femoral condyle and achieved full osteochondral healing. At the time of final follow-up, 1 of these 16 (6.3%) patients who received talar allograft as OLT treatment had developed asymptomatic anterior ankle arthritis upon radiographs. Conclusion: Using fresh talar osteochondral allograft provided results that were comparable to the use of distal femoral osteochondral autograft for treating recurrent or large OLTs. Although the use of allograft avoided the risk of knee complications when harvesting autograft from the distal femur, fresh talar allograft may have lower healing rates than osteochondral autograft. Level of Evidence: Level II, comparative case series.

Background Aim of this investigation was to analyze whether patients undergoing humeral head resurfacing (HHR) surgery are able to successfully return to their sports and occupation afterwards. Materials and methods Fifty patients treated with CUP (HHR) arthroplasty were included. Two groups were built: Patients who have participated in sports less than 5 years prior surgery (Group 1: n = 42 (84%)) and patients who have never participated in sports (Group 2: n = 8 (16%)). Evaluation was based on a questionnaire asking for types of sports, frequency, time to return to sports and work as well as limitations in work life. Results Mean age at the time of surgery was 58.6 (36–84) years in Group 1 and 65 (56–75) years in Group 2. Mean time follow-up was 5.5 years (2.5–12) years. Twenty-seven (64%) patients in Group 1 participated in sports right before surgery. Twenty-one patients (50%) returned to sports after surgery. The returning rate was 78%. Seven (17%) patients in Group 1 stated that the reason they underwent shoulder replacement surgery was to continue to participate in sports. Swimming and skiing were two of the most favorable sports. Two (4%) patients had to change their profession due to surgery. Most of the patients were retired at follow-up. Conclusion Most of the active patients undergoing HHR surgery are successfully able to return to their sports activities after surgery. Patients employed were able to return to their occupation after surgery. Many patients were already retired at the time of follow up.

Over the years there have been numerous anecdotal reports of nasal tip enlargement and loss of tip definition post rhinoplasty. Subsequent revisionary procedures not only failed to reduce the tip size but aggravated the problem causing an even larger and less defined nasal tip. The final result was often worse than the preop condition and uncorrectable. Six patients who demonstrated an aggravation of the postop result with subsequent revisionary or secondary surgeries were evaluated to find common causes or circumstances. All patients had 1) worsening of nasal tip result with subsequent procedures, e. g., nasal tip enlargement and/or loss of tip definition with subsequent procedures 2) exhibited substantial postop edema at one or more surgeries and 3) extensive subcutaneous fibrous tissue noted at revisionary procedures. The nasal scenario described is referred to as postrhinoplasty fibrotic syndrome. It is recommended that if revision surgery is necessary by a surgeon, the scale of the surgery should be smaller than that of the primary operation. If yet another revision is necessary that surgery should be of an even smaller scale than the prior surgery. Augmentation rather than reduction rhinoplasty is clearly a better approach. With the surgical philosophy of smaller and/or less surgery with each revision (should it be necessary) the irreversible condition of postrhinoplasty fibrotic syndrome should be avoidable.

Laparoscopic cholecystectomy (LC) is commonly performed in patients who can pose technical challenges, such as obesity, prior surgery, and subsequent incisional hernias. A new technique, the subcostal trocar approach using four 5-mm with exclusive removal (STAUFFER) LC, was developed to diminish these impediments and is highly advantageous.A retrospective review was performed of medical records for 389 patients who underwent LC from June 2011 through December 2016. STAUFFER LC involves (1) steep patient positioning, (2) visualized 5-mm trocar entry in the right abdomen, (3) use of three additional right subcostal trocars, and (4) gallbladder extraction from the high right lateral trocar site. Patient characteristics, operative details, and outcomes were analyzed and compared.STAUFFER LC was used in 255 patients (65.6%), and standard four-trocar LC (SLC) was performed in 134 patients (34.4%). Overall indications for surgery included chronic cholecystitis (71.7%), acute cholecystitis (19.8%), polyp (2.3%), and other (5.9%). No significant differences were detected in comorbidities and American Society of Anesthesiologists classification between the two patient groups. More patients in the STAUFFER LC group had previous midline abdominal surgery (P = .06) and significantly higher body mass index (P = .03), and they required less operative time (P .001). No patient had an entry site injury. No significant difference was noted in morbidity. One patient required a second laparoscopic operation for bleeding. One patient with Crohn's disease and "hostile abdomen" had an enterocutaneous fistula that closed spontaneously. In the SLC group, trocar site hernia (TSH) developed in 3 patients.STAUFFER LC is widely applicable and effective, saving operative time and reducing the risk of TSH. It is especially advantageous for obese patients who have had previous surgery.

Background: Prostatectomy is associated with short- and long-term morbidity, which includes attenuation of muscle function and deterioration of lean body mass. Physical function is a known predictor of morbidity and mortality, with initial evidence indicating that presurgical exercise is associated with fewer postsurgical complications and shorter hospitalization. The aim was to determine the feasibility of a supervised presurgical exercise program for prostate cancer (PCa) patients scheduled for prostatectomy. Methods: Ten men (68+6.4 years old) with localized PCa undertook a 6-week resistance and aerobic exercise program prior surgery. Training was undertaken twice weekly and patients were assessed at baseline, presurgery, and 6 weeks postsurgery. Outcome measures included muscle and physical performance, body composition, urinary incontinence and questionnaire. Results: Muscle strength increased by 7.5% to 24.3% ( P < .05) from baseline to presurgery but decreased to pretraining levels postsurgery, except for knee extensor strength ( P = .247). There were significant improvements ( P < .05) in the 6-m fast walk (9.3%), 400-m walk (7.4%), and chair rise (12.3%) at presurgery. Following surgery, improvements in physical performance were maintained. There was no change in lean or fat mass prior to surgery, but lean mass declined by 2.7 kg ( P = .014) following surgery. There were no adverse effects from the exercise program. Conclusions: Exercise undertaken prior to prostatectomy improved muscle and physical performance, with functional benefits maintained 6 weeks postsurgery. Presurgical exercise for PCa patients has the potential to facilitate recovery by improving physical reserve capacity, especially in men with poor muscle nd physical performance.

Aim: Compare radioembolization (Y90) and chemoembolization (CE) for the treatment of unresectable intrahepatic cholangiocarcinoma (UICC). Materials & methods: Institutional Review Board-approved, retrospective search was performed. Forty patients with UICC were treated with either Y90 (n = 25, 39 treatments) or CE (n = 15, 35 treatments). Comparative analysis was performed using Student's t and fisher-exact tests. Multivariable-logistic regression was also performed. Results: Median ages were 60 and 64 years for CE and Y90 groups, respectively (p = 0.798). Patient variables including age, Eastern Cooperative Oncology Group score, tumor burden, extra-hepatic disease, prior chemotherapy and prior surgery were similar between groups. Adverse events were similar in both groups (CE 20%, Y90 26%; p > 0.9). Overall response rate (CE 6%, Y90 4%; p > 0.9) and disease control rate (CE 46%, Y90 48%; p > 0.9) were statistically similar. Multilogistic regression did not identify any variables that correlated with disease control rate, including Eastern Cooperative Oncology Group score and tumor burden. Conclusion: Our observation shows that CE and Y90 display similar toxicity and disease control in the treatment of UICC.

Background Frameless image-guided radiosurgery (IGRS) is a safe and effective noninvasive treatment for trigeminal neuralgia (TN). This study evaluates the use of frameless IGRS to treat patients with refractory TN. Methods We reviewed the records of 20 patients diagnosed with TN who underwent frameless IGRS treatments between March 2012 and December 2013. Facial pain was graded using the Barrow Neurological Institute (BNI) scoring system. The initial setup uncertainty from simulation to treatment and the patient intrafraction uncertainty were measured. The median follow-up was 32 months. Results All patients' pain was BNI Grade IV or V before the frameless IGRS treatment. The mean intrafraction shift was 0.43 mm (0.28-0.76 mm), and the maximum intrafraction shift was 0.95 mm (0.53-1.99 mm). At last follow-up, 8 (40%) patients no longer required medications (BNI 1 or 2), 11 (55%) patients were pain free but required medication (BNI 3), and 1 (5%) patient had no pain relief (BNI 5). Patients who did not have prior surgery had a higher odds ratio for pain relief compared to patients who had prior surgery (14.9, P = 0.0408). Conclusions Frameless IGRS provides comparable dosimetric and clinical outcomes to frame-based SRS in a noninvasive fashion for patients with medically refractory TN.

527 Background: About 50% of patients undergoing post-chemotherapy retroperitoneal lymph node dissection (pcRPLND) are overtreated due to missing markers or valid prediction scores prior surgery. The potential of radiomics and machine learning applied on computed tomography (CT) imaging to predict the presence of viable tumor or teratoma in retroperitoneal lymph node metastases from germ cell tumor (GCT) patients prior to pcRPLND has not been explored. Therefore, we applied radiomics and machine learning to CT images of GCT patients prior to pcRPLND. Methods: Metastasized GCT patients who were treated with chemotherapy and received a contrast-enhanced CT prior to pcRPLND possessing complete clinical data were included in the study. Only lymph nodes which were identified in the CT images and correlated with the pathological findings (benign: necrosis / fibrosis vs. viable: viable tumor/ teratoma) were included. Lymph nodes identified in the CT images, were semiautomatically segmented and 93 radiographic features were analyzed. A linear support vector machine (SVM) algorithm was applied to analyze reproducible radiomics features. Additionally, a continuous reduction of the features analyzed was performed using Random Forest algorithms, as well as consecutive correlation and receiver operating curve analyzes. Results: Forty-two patients fulfilled the inclusion criteria and were included in the study. Total in these patients 96 lymph nodes were segmented on CT. Histologically, 41 lymph nodes were classified as viable tumors and 55 as benign. To train the SVM, 67 lymph nodes were randomly selected. Of the 93 radiomic features analyzed, 51 features were reproducible. Applying the trained algorithm to the remaining 29 lymph nodes resulted in a classification accuracy of 82% with a diagnostic sensitivity of 81% and a specificity of 83%. After multistep feature reduction, the three most important predictors for viable tumor achieved a sensitivity of 66% and a specificity of 78% when combined in a multivariate model. Conclusions: The applied radiomics model, solely based on CT images achieved a good sensitivity and specificity in predicting viable metastases.

Introduction Prolactinoma is the most frequent functioning pituitary adenoma. Most commonly occurs as microprolactinoma (less than 1 cm in size), which may be cured with medical therapy, but few long-term studies are available about optimal duration of treatment with dopamine agonists to ensure cure after drug discontinuation and its withdrawal without recurrence are do not report consistent results. Objective To establish criteria for cure of microprolactinoma with medical treatment and to analyze the potential predictors involved. Patients A retrospective study was conducted on 47 adult women with microprolactinoma followed up between 1975 and 2010; none of them had undergone prior surgery or radiotherapy, and all of them received treatment with a dopamine agonist for at least 4 years. They were divided into two groups for analysis: cured patients with at least 4 years with normal prolactin levels after drug discontinuation, and not cured patients. Results Cure was achieved in 57.4% of patients. Only age at diagnosis was a significant predictor: there were more young patients in the cured group and youngest patients needed less time to cure. Development of empty sella turcica or normal MRI was similar regarding time to cure. Conclusions Microprolactinoma may be cured with dopamine agonists, and life-long treatment is not required, although more than 10 years may be required to achieve cure, 11.6 ± 5.3 years in our experience.

Importance The effect of different rhinoplasty maneuvers on alar retraction remains to be elucidated. Objective To determine the etiology and treatment of alar retraction based on a series of specific rhinoplasty maneuvers. Design Retrospective review of a single surgeon’s rhinoplasty digital photo database, examining preoperative alar retraction from January 1, 2002, to December 31, 2005, in 520 patients. Patients with more than 1 mm of alar retraction on preoperative photographs were identified. Postoperative photographs were examined to determine the effect of specific rhinoplasty maneuvers on the position of the alar margin; these maneuvers included cephalic trim, cephalic positioning of the lower lateral cartilage, composite grafts, alar rim grafts, alar batten grafts, and overlay of the lower lateral cartilage. Setting Tertiary care academic health center. Participants Forty-five patients with alar retraction met inclusion criteria, resulting in 63 nasal halves with alar retraction. Main Outcomes and Measures Intraoperative findings, postoperative results. Results Forty-seven percent of the patients (n = 21) had prior surgery; 47% also had cephalically positioned lower lateral cartilages. Among patients with less than 4 mm of cartilage width at the outset, 46% of those who received supportive grafts achieved target correction vs only 7% for patients who did not undergo supportive cartilage grafting. In patients who underwent more than 4 mm of cephalic trim, those who received supportive grafts achieved 46% of target correction vs 11% among those who did not. Ninety-five percent of composite grafts, 69% of alar strut grafts, 47% of alar rim grafts, 43% of vertical lobule division, and 12% of alar batten grafts achieved their target correction values. Conclusions and Relevance Alar retraction is a highly complex problem. It can be seen de novo and is associated with cephalically positioned lower lateral cartilages. Structurally supportive grafting—including composite grafts, alar strut grafts, alar rim grafts, vertical lobule division, and alar batten grafts—can improve alar retraction. Level of Evidence 4.

Rectovesical Fistula (RVF) is an uncommon complication of radical prostatectomy and management can be challenging due to the deep location in the pelvis and prior surgery. Our objective is to describe a reproducible robotic technique for transabdominal repair of RVF with omental flap interposition. Appropriate operative setup and technique are keys to a successful and durable repair. We aim to provide a concise draft on an established technique for robotic RVF repair that may serve as a guide to the novice robotic surgeon.

Abdominal intercostal hernia is an uncommon phenomenon, reported in few case reports and small case series. If left untreated, it can lead to strangulation and visceral ischemia. Prompt diagnosis and appropriate surgical intervention are thus critical to prevent resulting morbidity. We present a 50-year-old woman with a large abdominal intercostal hernia after an open nephrectomy. She underwent a successful robotic repair of the hernia with mesh placement. Through the presentation, we would like to raise awareness of intercostal hernia as a complication of open nephrectomy and significance of early diagnosis in avoiding potential morbidity. We also performed a review of literature especially focusing on acquired abdominal intercostal hernia secondary to prior surgery. Although intercostal hernias can be difficult to repair secondary to the size and location, adequate visualization and surgical planning are critical to successful repair.

Radiation effects on tissues greatly complicate reconstruction of head and neck defects. We discuss the unfavorable surgical conditions set up by prior surgery and radiation in patients undergoing salvage ablation of recurrent cancer. With the focus on vessel selection, flap donor site characteristics, and management of potential complications, we hope to highlight some of the lessons learned from these complex cases. Special attention is given to the topic of laryngopharyngeal reconstruction.

Objective: To analyze the clinical situations that leads us to carry out curettage after cesarean section, the ultrasound prior surgery, intraoperative, and pathological findings. Methods: A retrospective study of all cases of postpartum curettage after cesarean section in a level 3 maternity unit. Results: There were 42 curettages to women with cesarean sections (1.6% of all cesarean sections). The indications for curettage were: fever: 21, methrorraghia: 11, and residual trophoblastic tissue: 10. In the previous ultrasound, all indicated curettages for retained trophoblastic tissue showed it, and in a lower proportion those indicated for fever (66.6%) or methrorraghia (22.2%). A total of fourteen curettages (35%) were performed without suspect image of retained tissue, and in all cases the surgeon described to obtain small amount of tissue. From material submitted to pathologic evaluation trophoblastic tissue was found in 64.7%, and there were no differences as curettage indication. Conclusions: When the previous ultrasound do not showed retained tissue, the surgeon did not remove retained material. When extracted there were always in small amounts. Therefore, it could be concluded that after cesarean section the curettage should be indicated only in the presence of evident ultrasound image of retained products.

To enhance the accuracy of radioactive seed implants in the head and neck, a digital model individual template, containing information simultaneously on needle pathway and facial features, was designed to guide implantation with CT imaging. Thirty-one patients with recurrent and local advanced malignant tumors of head and neck after prior surgery and radiotherapy were involved in this study. Before (125)I implants, patients received CT scans based on 0.75mm thickness. And the brachytherapy treatment planning system (BTPS) software was used to make the implantation plan based on the CT images. Mimics software and Geomagic software were used to read the data containing CT images and implantation plan, and to design the individual template. Then the individual template containing the information of needle pathway and face features simultaneously was made through rapid prototyping (RP) technique. All patients received (125)I seeds interstitial implantation under the guide of the individual template and CT. The individual templates were positioned easily and accurately, and were stable. After implants, treatment quality evaluation was made by CT and TPS. The seeds and dosages distribution (D(90),V(100),V(150)) were well meet the treatment requirement. Clinical practice confirms that this approach can facilitate easier and more accurate implantation.

Background/Aims. Intraperitoneal intraoperative hyperthermic chemotherapy (HIPEC) has been used in the treatment of ovarian cancer. The purpose of the study is to determine the efficacy of HIPEC after cytoreductive surgery in advanced ovarian cancer. Patients/Methods. From 2006 to 2010 patients with advanced ovarian cancer were enrolled in a prospective nonrandomized study to undergo cytoreductive surgery combined with HIPEC. Clinical and histopathological variables were correlated to hospital mortality, morbidity, survival, and recurrences. Results. The mean age of 43 women was 5 9 . 9 ± 1 3 . 8 (16–82) years. The hospital mortality and morbidity rate were 4.7% and 51.2%, respectively. Complete cytoreduction was possible in 69.8%. The overall 5-year survival rate was 54%. The prognostic indicators of survival were the extent of prior surgery ( 𝑃 = 0 . 0 4 8 ) and the extent of peritoneal dissemination ( 𝑃 = 0 . 0 1 1 ). The recurrence rate was 30.2%. Conclusions. Maximal cytoreductive surgery combined with HIPEC is a well-tolerated, feasible, and promising method of treatment in advanced ovarian cancer.
