AIM Conventional surgical management of colovesical and colovaginal fistulas can be morbid and is contraindicated in many patients. Our aim in this work is to evaluate our experience in the management of colovesical and colovaginal fistulas with endoscopic over-the-scope (OTS) clips. METHOD A retrospective review of all patients who underwent attempted endoscopic OTS clip management of colovesical and colovaginal fistulas between 2013 and 2020 was performed. Preoperative risk factors, operative details and postoperative outcomes are reported. RESULTS Ten patients were identified. Fistula types were: colovesical (five), rectovesical (two), colovaginal (two) and rectovaginal (one). The aetiology of the fistula was diverticular disease in seven (70%) cases and surgical complication of pelvic surgery in three (30%). The mean defect age was 157 ± 98 days, the mean defect diameter was 4.5 mm (range 2-10 mm) and the mean fistula length was 15 mm (range 2-25 mm). In nine (90%) cases, fistula identification and cannulation were performed through the nonenteric lumen of the fistula. Initial management with an OTS clip was technically successful in eight (80%) patients. Of the eight patients who underwent OTS clip placement, long-term success (mean follow-up 218 days, range 25-673 days) was achieved after initial intervention in four (50%) patients. One patient underwent serial OTS clip procedures and achieved long-term success after four interventions; three patients have not undergone a repeat procedure after initial failure. CONCLUSION Endoscopic management of colovesical and colovaginal fistulas with OTS clips offers a promising therapeutic option for patients with contraindications to conventional surgical management. Immediate technical success and long-term success rates are similar to other gastrointestinal tract applications of OTS clips.

To determine the preoperative risk factors most predictive of prolonged length of stay (LOS) or admission to a skilled nursing facility (SNF) or inpatient rehabilitation center (IPR) after free flap reconstruction of the head and neck.Retrospective cohort study.Tertiary academic medical center.Retrospective review of 1008 patients who underwent tumor resection and free flap reconstruction of the head and neck at a tertiary referral center from 2002 to 2019.Of 1008 patients (65.7% male; mean age of 61.4 years, SD 14.0 years), 161 (15.6%) were discharged to SNF/IPR, and the median LOS was 7 days. In multiple linear regression analysis, Charlson Comorbidity Index (CCI;Common tools for assessing frailty and need for additional care may be inadequate in a head and neck reconstructive population. CCI appears to be the best of the aggregate metrics assessed, with significant relationships to both LOS and placement in SNF/IPR.

OBJECTIVES/HYPOTHESIS To identify factors that may increase the risk of unplanned admission following elective outpatient endoscopic sinonasal surgery (ESS). STUDY DESIGN Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP). METHODS All cases of ESS were extracted from the 2010 to 2018 NSQIP database using Current Procedural Terminology codes. Only cases coded as outpatient, elective, and nonemergent procedures were included. Unplanned admissions were defined as cases with a total hospital stay of 1 day or more. Univariate and multivariate analyses were performed to identify variables that independently predicted unanticipated admission. RESULTS A total of 971 cases met inclusion criteria, of which 274 (28.2%) were unanticipated admissions. Patients in the unplanned admission group were more likely to be older (46.8 vs. 41.1 years, P

INTRODUCTION Despite increasing reports of laparoscopy for strangulated small bowel obstruction (SSBO), there is no consensus on outcomes in patients with SSBO. We evaluated the safety and utility of laparoscopy for SSBO and investigated the preoperative risk factors for laparotomy. METHODS This retrospective study included 107 patients who underwent emergency surgery for SSBO over a period of 6 years. Patients' characteristics and surgical parameters were compared between 27 patients undergoing laparoscopy alone (group L) and 80 patients undergoing laparotomy (group O, including conversion). Univariate and multivariate analyses were performed to determine risk factors for laparotomy. RESULTS Compared with group L, group O had significantly shorter operation time (59 vs 115 minutes, P

BACKGROUND Pancreaticobiliary malignant diseases are primarily treated by surgical resection. However, the surgical indications for elderly patients, especially for pancreaticoduodenectomy (PD), must be carefully considered due to patient compliance. Whether PD can contribute to better prognoses in elderly patients remains unclear. Therefore, we aimed to evaluate the complications, compliance, and survival of elderly and non-elderly patients who underwent PD in our department. METHODS We retrospectively analyzed 282 patients who underwent PD from 2000 to 2017 and divided them into non-elderly (aged ≤ 79 years, n = 238) and elderly (aged ≥ 80 years, n = 44) groups. The estimation of physiologic ability and surgical stress (E-PASS) system was used to evaluate morbidity and mortality using preoperative risk score (PRS), surgical stress score (SSS), and comprehensive risk score (CRS). RESULTS Preoperative risk score was higher in the elderly group than in the non-elderly group, although SSS and CRS were similar. No significant differences were detected in the occurrence of postoperative complications. In the elderly group, CRS was higher in patients with complications than in those without. Long-term outcomes evaluated by overall and disease-specific survival were not significantly different. CONCLUSIONS In the elderly patients, E-PASS especially CRS can predict the occurrence of complications. The safety and prognoses of elderly patients after PD are comparable with those of non-elderly patients.

Background For patients with Grade III acute cholecystitis (AC), several factors have been proposed in the 2018 Tokyo guidelines as caution signs in performing early surgery. However, these factors have not been externally validated in detail. Methods This retrospective study examined 35 patients who had been diagnosed with Grade III AC and treated with laparoscopic cholecystectomy between January 2008 and July 2019. The patients were allocated into an early group (patients who underwent surgery within 7 days of admission, n = 28) and a delayed group (patients who underwent surgery at least 8 days after admission, n = 7). Comparisons were made between these groups. Results No patients died. Significantly more patients required a conversion to open surgery (0% vs 28.5%, P = .003) or conversion to subtotal cholecystectomy (25.0% vs 71.4%, P = .020) in the delayed group than in the early group, and the total length of postoperative stay was significantly longer in the delayed group (11.4 vs 27.2 days, P = .001). The presence of negative predictive factors or risk factors listed in the 2018 Tokyo guidelines was not associated with death or postoperative complications. Conclusions Early surgery was considered appropriate and feasible for select patients who had Grade III AC and preoperative risk factors.

BACKGROUND We assessed the differences in postoperative feeding outcomes when comparing early and traditional diet advancement in patients who had an ostomy creation. METHODS At a U.S. tertiary care hospital, data from patients who underwent an ileostomy or colostomy creation from June 1, 2013, to April 30, 2017 were extracted from an institutional database. Patients who received early diet advancement (postoperative days 0 and 1) were compared with traditional diet advancement (postoperative day 2 and later) for demographics, preoperative risk factors, and operative features. The postoperative feeding outcomes included time to first flatus and ostomy output. Mann-Whitney U tests determined bivariate differences in postoperative feeding outcomes between groups. Poisson regression was used to adjust for unequal baseline characteristics. RESULTS Data from 255 patients were included; 204 (80.0%) received early diet advancement, and 51 (20.0%) had traditional diet advancement. Time to first flatus and time to first ostomy output were significantly shorter in the early compared with traditional diet advancement group (median difference of 1 day for both flatus and ostomy output, P < 0.001). Adjusting for baseline group differences (American Society for Anesthesiology Physical Status Classification System, surgical approach, resection and ostomy type) maintained the significant findings for both time to first flatus (β = 1.32, P = 0.01) and time to first ostomy output (β = 1.41, P < 0.001). CONCLUSIONS Early diet advancement is associated with earlier return of flatus and first ostomy output compared with traditional diet advancement after the creation of an ileostomy or colostomy.

Objective Nationwide databases are expected to provide critical data to improve medical practice. The present study used such data to develop risk models for clinically important outcomes after right hemicolectomy based on preoperative risk factors. Methods Japan's National Clinical Database (NCD) identified 38 030 cases of right hemicolectomy in the years 2011 and 2012. These were used to analyze correlations between mortality and eight selected clinical outcomes of interest by Pearson's correlation coefficient (r). To construct risk models for the eight selected clinical outcomes, 80% of all the examined cases were extracted randomly as a development cohort, and preoperative risk factors for each clinical outcome were identified using a forward stepwise selection method. Morbidities predicted from the risk models were used to find areas under the receiver operator curves among the remaining 20% of the testing cohort. Results The following clinical outcomes were identified as highly associated with operative mortality: systemic sepsis (r = .360), renal failure (r = .341), unplanned intubation (r = .316) and central nervous system (CNS) occurrences (r = .301). Risk models containing up to 21 preoperative variables were constructed for these eight postoperative clinical outcomes. Predictive values of the eight models were as follows: surgical site infections (0.634), anastomotic leakage (0.656), systemic sepsis (0.816), pneumonia (0.846), unplanned intubation (0.838), renal failure (0.883), CNS occurrences (0.833) and transfusion >5 units (0.846). Conclusions This study indicated that the NCD‐generated risk models for six of the eight selected critical postoperative outcomes had high discrimination among right hemicolectomy patients. These risk models can accurately identify high‐risk patients prior to surgery., This article is the first study that shows risk models for eight clinically important factors for morbidity after right hemicolectomy, based on preoperative risk factors. Our models and their evaluations are based on data from the NCD in Japan for the years 2011 and 2012.

Profiling recovery following knee replacement (KR) is a focus of substantial research interest because KR surgery has become one of the most common major surgical procedures. In the United States, for example, approximately one million KRs are performed annually. Additionally, there is substantial clinical practice and research interest in the study of poor pain outcome and predictors of poor pain outcome following KR.

This study analyzes the preoperative risk factors for intra-operative bleeding in our recent series of pediatric LTs. Between November 2009 and November 2014, 84 consecutive isolated pediatric LTs were performed in 81 children. Potential preoperative predictive factors for bleeding, amount of intra-operative transfusions, postoperative course, and outcome were recorded. Cutoff point for intra-operative HBL was defined as intra-operative RBC transfusions ≥1 TBV. Twenty-six patients (31%) had intra-operative HBL. One-year patient survival after LT was 66.7% (CI 95%=[50.2-88.5]) in HBL patients and 83.8% (CI 95%=[74.6-94.1]) in the others (P=.054). Among 13 potential preoperative risk factors, three of them were identified as independent predictors of high intra-operative bleeding: abdominal surgical procedure(s) prior to LT, factor V level ≤30% before transplantation, and ex situ parenchymal transsection of the liver graft. Based on these findings, we propose a simple score to predict the individual hemorrhagic risk related to each patient and graft association. This score may help to better anticipate intra-operative bleeding and improve patient's management.

Although transcatheter aortic valve implantation (TAVI) has been indicated for patients with high surgical risk, indications for or against the procedure become more difficult as vascular access becomes more proximal and/or invasive in order to accommodate patients with even higher risks. We compared preoperative factors including the European System for Cardiac Operative Risk Evaluation (EuroSCORE) and Society of Thoracic Surgeons Predicted Risk of Mortality (STS) score with postoperative survival in 195 patients undergoing TAVI during 2.5 years (January 2010 to June 2012), when vascular access routes were developed from iliofemoral (IL/Fm access, n = 149), axillo-clavicular, apical, and direct aortic approaches (alternative access, n = 46). Logistic regression analyses showed that alternative access was associated with reduced 30-day survival (P = 0.024), while high surgical risk (>15% in both EuroSCORE and STS score) was associated with reduced 1-year survival (P = 0.046). Thus, patients treated via IL/Fm access had acceptable outcome regardless of preoperative risk levels while patients with low surgical risk ( 15%) requiring alternative access, had a prohibitive risk in our experience, they might have been considered untreatable or not amenable even to TAVI and offered medical or alternative managements.

SummaryBackground Although some studies have investigated the potential predictors of perioperative mortality, there are few specifically for pediatrics. Objective The aim of the retrospective study was to analyze potential preoperative risk factors and to develop a pediatric preoperative risk prediction score (PRPS), and to predict postoperative ICU admission and the incidence of perioperative death in pediatric patients. Methods Patients who postoperatively admitted to ICU or died (occurred within 30 days after the surgery) from 263 607 pediatric surgical patients with age from 1 day to 14 years old in eight centers in China from October 2010 to September 2013 were retrospectively analyzed. About 5500 non-ICU admission and death patients were randomly selected from those 263 607 patients as controls for analysis comparison. Independent risk factors and a risk model were derived from these analyses, and were further assessed with the likelihood ratio test and the area under the receiver operating characteristic (ROC) curve. Results There were 1812 ICU admission or death patients but 187 patients’ records are incomplete. There were 487 patients with incomplete records among 5500 controls. Collectively, data from 6626 patients were enrolled in final analyses. With multiple logistic regression analysis, age, ASA physical status, SpO2, prematurity, and unfasted status were found to be independent predictors for critical patients. The AUC value of 0.905 indicated excellent predictive performance between critical and noncritical predictors. Conclusions Our study revealed that age, ASA physical status, SpO2, prematurity, and unfasted status are risk factors to predict postoperative ICU admission and death in pediatric patients.

Background: Hepatobiliary surgeons continue to expand the pool of patients undergoing liver resection using combinations of surgical and interventional procedures with chemotherapy. Improved perioperative care allows for operation on higher risk surgical patients. Postoperative outcomes, including 90-day mortality that improved over the past decade but still varies across cohorts. This study developed a preoperative risk score, on the basis significant clinical and laboratory variables, to predict 90-day mortality after hepatectomy. Methods: All patients who underwent hepatectomy between 2011 and 2016 were included. Univariable and multivariable analyses were performed to identify the predictors of postoperative mortality and a risk score was derived and validated. Results: The overall 90-day mortality rate in the derivation cohort (n = 1269 patients) was 4.0% (N = 51). Increasing patient age (P < 0.001), extent of resection (P = 0.001), diabetes mellitus (P = 0.006), and low preoperative sodium (P = 0.012) were predictors of the increased 90-day mortality in the multivariable analysis. The risk model developed based on these factors had an AUROC of 0.778 (P < 0.001) and remained significant in a validation cohort of 788 patients (AUROC: 0.703, P < 0.001). Conclusion: The proposed preoperative risk score to predict 90-day mortality after liver resection could be useful for appropriate counseling, optimization, and risk-adjusted assessment of surgical outcomes.

Aim The general assumption that non-elective cardiac procedures in octogenarians are related to poor postoperative outcomes and quality of life (QOL) might lead to a non-justified exclusion of elderly patients from surgical treatment. The aim of the present study was to assess survival, functional outcome and quality of life of octogenarians undergoing non-elective cardiac surgery. Methods Between 2009 and 2011, 62 consecutive octogenarians (mean age 83.5 ± 3.5 years) underwent urgent (n = 33) or emergency (n = 29) cardiac surgery. In 69% of patients, coronary artery bypass grafting was carried out, and 24% of patients underwent coronary artery bypass grafting plus valve surgery. Preoperative risk, as well as the postoperative course, was analyzed. All discharged patients were contacted to gain information about survival, functional capacity and QOL using the Barthel Mobility Index and the Short Form 12 Health Survey questionnaire. Results were compared with age-adjusted population data. Results In-hospital mortality was 32.3% overall, 9.3% in urgent cases and 56.7% in emergency cases. After a mean follow-up period of 447 ± 359 days, survival of the discharged patients was 93.1% (urgent) and 76.9% (emergency), respectively. QOL measures of the survivors were equivalent to those of the general elderly population. Functional capacity, calculated with Barthel Index, was high in both groups (86 ± 13 and 81 ± 21). A total of 92% of the patients were living at home. Conclusions Although non-elective cardiac surgery in the elderly is related to high in-hospital mortality, physical and psychological recovery of the survivors is encouraging. QOL equals that of the general elderly population, and good functional status offers a highly independent life. Therefore, age per se should not disqualify patients from urgent or emergency cardiac surgery. Geriatr Gerontol Int 2015; ●●: ●●–●●.

Aim Surgery for rectal and sigmoid cancer is a model setting for investigating preoperative information provision and shared decision making (SDM), as the decision consists of a trade-off between the pros and cons of different treatment options. The aim of this study was to explore surgeons' opinion on the preoperative information that should be given to rectal and sigmoid cancer patients and to evaluate what is actually communicated. In addition, we assessed surgeons' attitudes towards SDM and compared these with patient involvement. Method A questionnaire was sent to Dutch surgeons with an interest in gastroenterology. Preoperative consultations were recorded. A checklist was used to code the information that surgeons communicated to the patients. The OPTION-scale was used to measure patient involvement. Results Questionnaires were sent to 240 surgeons, and 103 (43%) responded. They stated that information on anastomotic leakage and its consequences, the benefits and risks of a defunctioning stoma and the impact of a stoma on quality of life were necessary preoperative information. In practice, patients were inconsistently informed of these items. Most participants agreed to using SDM in their consultations. However, in practice, most patients were offered only one treatment option and little SDM was seen. The mean OPTION-score was low (7/100). Conclusion Insufficient information is given to patients with rectal and sigmoid cancer to guide them on their preferred surgical option. Information should be given on all treatment options, together with their complications and outcome, before any decision is made.

Given emerging demographic trends, many more elderly patients are being diagnosed with head and neck cancers. The surgical care paradigm for this cohort of patients must take into account specific challenges inherent to geriatric perioperative management. This article attempts to summarize the existing body of literature relevant to the geriatric head and neck cancer population, and to extrapolate relevant data from geriatric perioperative medicine in order to better understand and guide management decisions. The involvement of geriatricians and of patients' primary care providers may be invaluable in assisting in complex perioperative decision-making and in participating in longitudinal management. Preoperative risk stratification and assessment of medical, social, and functional variables are critical for appropriate decision-making in this challenging patient population. © 2013 Wiley Periodicals, Inc.

This article reports the results of a single-centre study which has applied prospective risk analysis to predict posterior capsule rupture or vitreous loss (PCR/VL) during cataract surgery at a tertiary teaching centre in New Zealand; this risk analysis was used to select cases for trainees based on risk of complications. Data was collected at Waikato Public Hospital from July 2014 to May 2017. A total of 646 cases were recorded for 9 surgeons: 1 consultant, 5 senior registrars and 3 junior registrars.

Aim: To identify the preoperative risk factors affecting the conversion to laparotomy during vaginal hysterectomy (VH) for benign uterine conditions. Material and Methods: The charts were reviewed for all patients who underwent VH between 1 January 2003 and 31 December 2008 at Hallym University Hospital, Seoul. Results: The rate of conversion to laparotomy was 3.7% (32 cases). Factors that were independently associated with the risk of conversion to laparotomy were found to be low parity (conversion 1.43 vs VH 1.92, P = 0.021), previous abdominal surgery (conversion 0.71 vs, VH 0.26, P = 0.012), pelvic adhesion (conversion 1.25 vs VH 0.04, P = 0.000), and large uterine weight (conversion 345.15 g vs VH 222.38 g, P = 0.005). In the conversion group, the operative time was longer (conversion 144.84 min vs VH 77.67 min, P = 0.000), and estimated blood loss was also greater (conversion 656.25 mL vs VH 358.47 mL, P = 0.00). Postoperative hemoglobin change (conversion 1.65 g/dL vs VH 1.23 g/dL, P = 0.046) and transfusion rate were also greater in the conversion group (conversion 0.75 vs VH 0.01, P = 0.001). Conclusion: VH is the main procedure for benign uterine disease and is successfully performed in most cases. But several factors, including low parity, previous abdominal surgery, pelvic adhesion and large uterine weight can affect the risk of conversion to laparotomy.

Background: It is not clear whether pathological changes following neoadjuvant hormonal therapy (NHT) prior to radical prostatectomy have any value as predictors of progression in prostate cancer. Methods: We conducted a study of 100 patients with prostate cancer who underwent radical prostatectomy following NHT. We used the Japanese general rule as the criterion to assess the biochemical recurrence rate and pathological changes after NHT. Results: In terms of preoperative risk factors, the probability of recurrence was significantly higher for patients with more than 20 ng/mL of pretreatment serum prostate-specific antigen (PSA) and/or a Gleason score of 7 or higher for biopsy specimens. We defined these pretreatment findings as high-risk factors. Among 65 patients with high-risk factors, patients with a post-NHT pathological effect of grade 3 according to the Japanese general rule showed no recurrence, whereas patients with a grade 0 had a poor prognosis. Patients with a PSA nadir 0.5 ng/mL or less tended to have a better prognosis. Conclusion: Despite preoperative high-risk factors, patients showing good pathological effects after NHT tend to have a favorable prognosis after radical prostatectomy. Therefore; assessment of the pathological effects of NHT using the Japanese general rule as the criterion proved to be useful for the prediction of biochemical recurrence.

Purpose: This study presents an evaluation of cataract surgery on diabetic patients. One experienced surgeon carried out phaco emulsification on all subjects and the same surface-coated one-piece PMMA-lens-type was implanted. The lens fluorescence and the blood-aqueous barrier (BAB) were then evaluated as experimental preoperative risk indicators. Results: During follow-up, 10 out of 39 diabetic patients progressed unilaterally in diabetic retinopathy or developed macular oedema, a significant relative risk. Neither lens fluorescence, BAB, HbA1c, level of retinopathy, type/duration of diabetes, diabetes treatment or antihypertensive treatment differed significantly between the group of patients with postoperative progression of retinopathy/macular oedema and those without. Results indicated NIDDM (non-insulin-dependent diabetes mellitus/type 2 diabetes) patients might have increased risk of a postoperative macular oedema. Conclusion: When diabetic retinopathy (DR) is not in a proliferative phase it should not be regarded as a contraindication to modern cataract surgery. Neither lens fluorescence nor BAB is valuable as a risk indicator for postoperative progression of DR.

Objective: 1) To determine the incidence of pressure ulcers (PU) post-prolonged head and neck surgery. 2) To determine the outcome of interventional strategies on PU development.Method: A prospective study between June 2008 and March 2011.Using the FOCUS-PDCA model, an improvement plan was developed in KFMC for patients undergoing surgery of 4-hour duration. A patient monitoring protocol was developed including a full demographic database, a preoperative risk assessment, an intraoperative prevention method with a skin integrity check list, and a postoperative skin assessment handover. The patients were monitored for signs of PU for the next 7 days. Possible risk factors along with pressure ulcer reduction interventions were evaluated.Results: During the study 230 H&N patients were monitored. The initial incidence of PU was 23.5%. After implementation of the specialty mattress, it decreased to 10%. With the use of additional mattresses, intra- and postoperative PU prevention documentation the incidence dec...
