BACKGROUND AND AIMS: The number of procedures performed by internal medicine residents in the United States (US) is declining. An increasing proportion of residents do not feel confident performing essential invasive bedside procedures and, upon graduation, desire additional training. Several residency programs have utilized the medical procedure service (MPS) to address this issue. We aim to summarize the current state of evidence by systematically evaluating the effect of the MPS on resident education, comfort, and training, as well as patient safety and procedural outcomes in the US. METHODS: We conducted a systematic review of all studies reporting the use of an MPS with supervision from a board-certified physician in internal medicine residencies in the US. Database search was performed on PubMed, Embase, ERIC, and Cochrane Library from January 2000 to November 2020 for relevant studies. Quality of evidence assessment and random-effects proportion meta-analyses were performed. RESULTS: A total of nine studies reporting on 3879 procedures performed by MPS were identified. Procedures were safely performed, with a pooled complication rate of 2.1% (95% CI: 1.0–3.5) and generally successful, with a pooled success rate of 94.7% (95% CI: 90.8–97.7). The range of procedures performed by residents under MPS was 6.7–72.8 procedures per month (n = 9) compared to 4.3–64.4 procedures (n = 4) without MPS. MPS significantly increased confidence, comfort, and use of appropriate safety measures among residents. CONCLUSION: There are a limited number of published studies on MPS supervised by a board-certified physician in US internal medicine residencies. Procedures performed by MPS are generally successfully completed and safe. MPS benefits internal medicine residents training by improving competency, comfort, and confidence.

Orbital floor fractures subsequently lead to consequences such as diplopia and enophthalmos. The graft materials used in orbital floor fractures varied from autografts to alloplastic grafts, which possess certain limitations. In the present study, a novel porcine bone matrix decellularized by supercritical CO2 (scCO2), ABCcolla® Collagen Bone Graft, was used for the reconstruction of the orbital framework. The study was approved by the institutional review board (IRB) of Kaohsiung Medical University Chung-Ho Memorial Hospital (KMUH). Ten cases underwent orbital floor reconstruction in KMUH in 2019. The orbital defects were fixed by the implantation of the ABCcolla® Collagen Bone Graft. Nine out of ten cases used 1 piece of customized ABCcolla® Collagen Bone Graft in each defect. The other case used 2 pieces of customized ABCcolla® Collagen Bone Graft in one defect area due to the curved outline of the defect. In the outpatient clinic, all 10 cases showed improvement of enophthalmos on CT (computerized tomography) at week 8 follow-up. No replacement of implants was needed during follow-ups. To conclude, ABCcolla® Collagen Bone Graft proved to be safe and effective in the reconstruction of the orbital floor with high accessibility, high stability, good biocompatibility, low infection rate and low complication rate.

Introduction CRT Survey II was initiated by the European Heart Rhythm Association and the Heart Failure Association, to explore everyday implantation practice of cardiac resynchronization therapy (CRT) devices in a broad spectrum of hospitals in European Society of Cardiology (ESC) member countries. Aim To compare Polish and European procedural practice. Material and methods Procedural details of Polish patients collected in 37 Polish centres (n = 1241 - Poland group) were compared to the patients enrolled throughout Europe (n = 9847 - CRT II Survey group). Results There were significant differences in: successful implantation (96.1% vs. 97.4%), type of device implanted (for CRT-D: 87% vs. 67.6%), implanting physician subspecialty (for electrophysiologist: 69.2% vs. 79.8%), type of location of procedure (for operating room: 19.4% vs. 8.9%), duration of procedure (117.8 ±44 vs. 97.5 ±46.1 min), left ventricle lead type (for multipolar lead: 50% vs. 57.9%), coronary sinus venogram with occlusion rate (41.4% vs. 47.9%) and peri-procedural complication rate (7.5% vs. 5.3%) between Poland and CRT II Survey groups, respectively. Conclusions This study provides important information describing current differences in Polish procedural routines in relation to ESC member countries. Heterogeneous CRT implantation practices across European countries still exist. However, it may be related to different clinical profile of patients qualified for CRT implantation in Poland as well as organization of care.

SUMMARY – The aim of the study was to reevaluate the safety and feasibility of discharge 24 h after elective uncomplicated laparoscopic cholecystectomy. Since the introduction of laparoscopic cholecystectomy in our hospital, the minimum postoperative stay was considered to be two days based on surgeons’ experience. The study included 337 operations performed by 21 surgeons during 2016 in the Sestre milosrdnice University Hospital Centre. Conversion to open technique and cases of acute cholecystitis were excluded, while 15 patients had insufficient postoperative data. The mean length of stay was 2.38 (range 1 to 6) postoperative days, median two postoperative days. Serious complications involving suspected drain bile leakage and postoperative hemorrhage occurred in two (0.59%) patients, both in the first 24 h following surgery. One patient required emergency laparotomy on the first postoperative day. Readmission rate was 1.2%. The postoperative minor complication rate was 42 of 337 (12.46%); these included wound infections, urinary tract infections, symptoms included in postcholecystectomy syndrome, etc. The onset of these complications was mostly after postoperative day 3. The data obtained suggest that discharge on the first postoperative day after elective uncomplicated laparoscopic cholecystectomy should be considered safe and can be practiced in our hospital.

Introduction In last three decades we have been observing development of minimally invasive walled-off pancreatic necrosis (WOPN) treatment techniques. The choice of access to the necrosis and technique of treatment depends not only on the position and spread of necrosis, but in the first place on the experience of the medical center. Aim To assess the effectiveness and safety of combined endoscopic and percutaneous drainage of WOPN. Material and methods We performed a retrospective analysis of 64 consecutive patients with symptomatic WOPN, who underwent endoscopic treatment in our department between 2011 and 2013. Results Additional percutaneous drainage was executed during endoscopic treatment in 20/64 (31.25%) patients. Complications of treatment occurred in 4/20 (20%) patients. Complications of treatment occurred in 4/20 (20%) patients. All these complications were related to endoscopic treatment. No complications related to percutaneous drainage were noted. There were no deaths. Therapeutic success was achieved in all 20 patients. No patients required surgery. The average time of endoscopic drainage was 41.4 (11-173) days. The mean number of endoscopic procedures was 4.2 (2-12). The average time of percutaneous drainage was 11.3 (5-20) days. The medium time of follow-up was 54 (48-64) months. During the observation the recurrence of WOPN was noted in 2/20 (10%) patients. Long-term success of combined drainage was achieved in 18/20 (90%) patients. Conclusions In selected patients with symptomatic WOPN combined endoscopic and percutaneous drainage enables a high success rate with a low procedure-related complication rate.

Objectives Chronic kidney disease (CKD) is associated with an increased complication rate after cardiac interventions. Although CKD has a high prevalence among atrial fibrillation patients, the impact of CKD on periprocedural complications and the outcome after an interventional left atrial appendage closure (LAAC) is unclear. The present study, therefore, aimed to investigate whether CKD influences the procedure’s effectiveness and safety. Methods LAARGE is a prospective, non-randomised registry. LAAC was conducted with different standard commercial devices, and the follow-up period was one year. CKD was defined by an eGFR 2, and subgroups were further analysed (i.e. eGFR 2, respectively). Results Two hundred ninety-nine of 623 patients (48.0%) revealed a CKD. The prevalence of cardiovascular comorbidity, CHA2DS2-VASc score (4.9 vs. 4.2), and HAS-BLED score (4.3 vs. 3.5) was significantly higher in CKD patients (each p p 2; p > 0.05 vs. eGFR 30–59 mL/min/1.73 m2). Non-fatal strokes were absolutely infrequent during follow-up (0 vs. 1.1%). Severe non-fatal bleedings were observed only among CKD patients (1.4 vs. 0%; p = 0.021). Conclusions Despite an increased cardiovascular risk profile of CKD patients, device implantation was safe, and LAAC was associated with effective stroke prevention across all CKD stages.

Introduction: Female stress urinary incontinence (SUI) is often treated surgically. Urethral bulking agents are a minimally invasive alternative, especially in patients suffering from intrinsic sphincter deficiency, but often with limited long-term efficacy. Urolastic® is a non-deformable, non-resorbable silicone elastomer that is used as an injectable. Its properties might result in a more durable response after injection. If this durability factor can be combined with a low complication rate, this can become a useful treatment option. We therefore assessed the subjective improvement and safety after treatment with Urolastic®. Materials and Methods: In 2 Dutch hospitals, 65 patients were treated with Urolastic®. The subjective improvement was assessed and the medical charts were reviewed for complications that appeared during the follow-up period. The complications were classified using the Clavien-Dindo classification. Results: We found that 76-88% of the patients showed subjective improvement at 12-25 months follow-up. The rate of improvement experienced was 50-70%. The rate of complications classified as Clavien-Dindo >II was 24-33%. The 12 patients with 75-100% subjective improvement after 2 months, showed 85% improvement after a median of 25 months. Conclusions: With careful patient selection, Urolastic® seems to be a safe, durable and effective treatment option for female SUI.

Introduction Single-port access laparoscopic lateral segmentectomy (LLS) has been developed as a novel minimally invasive surgery. We have experience with this LLS technique. Aim To report our technique and patients' postoperative course in a series of single-port access LLS performed in our department. We also examine the cosmetic outcome, safety, and utility of the procedure. Material and methods Between February 2010 and October 2016, 54 patients who underwent single- or multiple-port laparoscopic or open lateral segmentectomy (LS) were retrospectively analyzed with respect to cosmetic outcome, safety, and utility. Results In the single LLS group, the laparoscopic procedure was successfully completed for all 14 patients. The median operative time was significantly shorter in the single LLS group (123 min; range: 50-270 min) than in the other groups. Estimated blood loss was also significantly lower in the single LLS group (10 ml; range: 0-330 ml). During the first 7 postoperative days, the visual analog scale pain score and the use of additional analgesia were not significantly different between groups. The single LLS group had a 7.1% complication rate (Clavien-Dindo classification > IIIA); this was not significantly different between groups. Conclusions Single-port access LLS is a procedure with excellent cosmetic results, although, with regard to invasiveness, there are no major differences from conventional LLS.

Purpose Central venous access ports (CVAP) are widely used to provide long-term vascular access for the delivery of chemotherapeutic medications. The aim of this study was to evaluate the clinical outcomes and complications following CVAP implantation in the interventional radiology suite. Material and methods A retrospective analysis was conducted on 937 oncology patients who underwent CVAP implantation between January 2009 and June 2017. Information regarding patient characteristics, operative data, and procedural outcomes was collected and analysed. Results A total of 937 patients scheduled for CVAP were included in the final analysis. Initial success was achieved in 930 patients (99.3%), and overall completion was achieved in 933 patients (99.6%). There were 63 complications overall. Among these, 19 (2.0%) occurred during the intra- and perioperative period and 44 were late complications (4.7%). No CVAP-related mortalities were observed. Conclusions The analysis in the present study revealed that the CVAP is a safe and effective route for long-term administration of chemotherapy with an overall complication rate of 6.7% throughout the entire device duration. The CVAP implantation procedure carried out in the interventional radiology suite provides an advantage in the management of procedural, vascular and catheter-related complications.

Interval laparoscopic cholecystectomy was found to be safe and associated with a low rate of perioperative complications., Background and Objectives: Up to 19% of patients undergoing laparoscopic cholecystectomy (LC) have common bile duct stones and may require endoscopic retrograde cholangiography (ERCP) before LC. The risk of complications of LC after ERCP is higher, and the optimal interval between ERCP and LC is disputed. In our unit, LC is performed approximately 6 weeks after ERCP. This study aims to compare outcomes between subsets of patients undergoing LC with or without prior ERCP. Methods: All patients undergoing ERCP and elective laparoscopic cholecystectomy (ELC) over a 1-year period were included. Outcome measures included ERCP outcomes, duration of surgery, intraoperative findings, and postoperative outcomes. Two groups of patients were compared: LC after ERCP and ELC. Results: The study included 190 ELC patients and 43 patients with LC after ERCP (ERCP-LC) (December 2008 to December 2009). At ERCP, 25 patients (58%) had ductal stones. The post-ERCP complication rate was 5%. The median time to LC was 42 days, and 6 patients (14%) were readmitted before LC. There were more severe adhesions and longer median operating times in the ERCP-LC group (75 minutes for ELC vs 110 minutes for ERCP-LC, P = .013). We found no significant differences in rates of conversion to open surgery, postoperative complications, lengths of stay, and readmission rates. Conclusion: Interval LC after ERCP is a more technically challenging procedure but is associated with a low rate of complications. Although there is emerging evidence that early LC after ERCP is feasible, our study shows that our current practice of delaying LC by approximately 6 weeks is safe.

The results of this study suggest that there is a significant increase in intraoperative and postoperative complications for obese patients undergoing laparoscopic adrenalectomy compared with healthy weight individuals., Objectives: Laparoscopic adrenalectomy has become the standard of care for resection of adrenal masses, with extremely low morbidity and mortality. This study investigates the difference in outcomes in patients who underwent laparoscopic adrenalectomy, comparing obese with healthy weight patients. Methods: A retrospective chart review was performed on patients undergoing laparoscopic adrenalectomy between January 2000 and February 2010. Intraoperative and postoperative complications in the patients were compared. A patient with a body mass index >30kg/m2 was considered obese. Results: Eighty patients underwent laparoscopic adrenalectomy between January 2000 and February 2010. Forty-nine patients (61%) were considered obese based on the body mass index criteria. Operative time, estimated blood loss, and length of stay did not differ significantly between the 2 cohort groups. There was no 30-day mortality in the population. There were 9 complications in the obese population and no complications in the healthy weight population (P

Introduction: A number of different adjustable gastric bands are available for laparoscopic adjustable gastric banding (LAGB). Few attempts have been made to compare the influence of band design differences for efficiency and complication rate and conflicting results have emerged from comparative studies. Aim: To compare SAGB (Swedish Adjustable Gastric Band) and MiniMizer Extra adjustable gastric bands. Material and methods: One hundred and three patients were included in the prospective randomized study. All patients underwent LAGB. The SAGB was used in 49 and MiniMizer Extra in 54 patients. The primary endpoint was weight loss, and secondary endpoints were complication rate, correction of co-morbidities and improvement of quality of life. Results: There were no early complications. A significant difference in the proportion of patients who have reached good or excellent weight loss results (≥ 50% of initial excess body mass index loss) was found in favour of the MiniMizer Extra group (29.6% vs. 8.2%, p = 0.006). No difference was found in other weight loss parameters, resolution of co-morbidities and improvement of quality of life. One oesophageal dilatation and one leakage were diagnosed in the MiniMizer Extra group. Five band penetrations (9.3%) were diagnosed in the MiniMizer Extra group and no penetrations in the SAGB group (p = 0.069). Conclusions: No major significant differences were found between the compared bands. Further results need to be confirmed by longer follow-up.

The aim of this study was to compare the functional outcome, quality of restoration, and complication rate after open reduction and internal fixation (ORIF) of displaced or unstable 2-, 3- and 4-part humeral fractures using two different locking plates.The data used in this analysis was prospectively collected in two large multicentre studies in 15 European Level 1 trauma centres. A total of 318 patients with proximal humeral fractures were treated with ORIF using either the locking proximal humerus plate (LPHP) or proximal humeral internal locking system (PHILOS). Outcome measurements included Constant and Neer scores, evaluation of local pain at the fracture site and complications, and radiographic assessment at one year.At one year, the mean Constant scores (relative to the contralateral shoulder) improved significantly for both groups and were above 80% for 2-, 3-, and 4-part fractures. A significantly shorter surgical time, less pain at the fracture site, and better functional outcome was achieved by PHILOS-treated patients with 2-part fractures throughout the one-year follow-up month and with 3-part fractures at three months (p 0.05). There was no difference between the treatment outcomes for 4-part fractures, and no difference in the complication rates (p 0.05).PHILOS and LPHP can be considered as useful implants for ORIF of displaced and unstable proximal humeral fractures. There was a slight advantage of the PHILOS system with regard to operative time and functional outcome, especially for the treatment of 2- and 3-part fractures.

Recent attention in THA has focused on minimally invasive techniques and their short-term outcomes. Despite much debate over the outcomes and complications of the two-incision and the mini-lateral and mini-posterior approaches, complications arising from use of the anterior THA on a fracture table are not well documented.We determined the intraoperative and postoperative complications with the anterior approach to THA through an extended single-surgeon patient series.We reviewed 800 primary THAs performed anteriorly with the aid of a fracture table over 5 years and recorded all intraoperative and postoperative complications up to latest followup (average, 1.8 years; range, 0-5 years). Patients with severe acetabular deformity or severe flexion contractures were excluded and those surgeries were performed with a lateral approach during the time period of this study.Intraoperative complications included 19 trochanteric fractures, three femoral perforations, one femoral fracture, one acetabular fracture, one bleeding complication, and one case of cardiovascular collapse. There were no ankle fractures. Postoperative complications included seven patients with dislocations; seven with deep infections; one with delayed femur fracture; 37 with wound complications, among which 13 had reoperation for local débridement; 14 with deep venous thrombosis; and two with pulmonary embolism; and 31 other nonfatal medical complications.The main intraoperative complications of trochanteric fractures and perforations occurred mostly early in the series, while the main postoperative complications related to wound healing were prevalent throughout the entire series. Despite potential advantages of use of a fracture table, surgeons should be aware of the potential complications of trochanteric fractures, perforations, and wound-healing problems associated with this technique.Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Complications of open tibial fractures have been found to be very frequent after application of monotherapies (external fixator, plate, intramedullary nailing). The use of combined therapy has improved our results. We treated 658 patients for open tibial fractures over a course of 15 years. Plating was the method of treatment in the initial phase, and then external fixators and unreamed tibial nails (UTN) were used as a monotherapy. In the last ten years the option of a combined therapy was at our disposal, namely, changing the method of treatment. Monotherapy was performed in 352 cases, and 270 patients were treated in a combined manner. The rate of septic complications could be reduced with the combined therapy from 15.5% to 6.6%, the rate of bone healing disorders from 31.6% to 8.7%, and that of amputations from 4.9% to 0.7%. Elaboration of therapeutic tactics and their consistent application increases the healing potential of open tibial fractures. During this 15 year period, our therapeutic concepts have changed, whereby gradual, combined therapy models were initiated, increasing the advantages and decreasing the disadvantages of the different methods.

The optimum operative technique for lateral lumbar disc herniations (LLDH) remains unclear, and both interlaminar and extraspinal approaches are used.To compare outcome after LLDH removal either by a lateral transmuscular approach (LTM) or by a combined interlaminar and paraisthmic approach (CIP).28 patients underwent surgery using CIP and 20 using LTM. All patients were operated on by the same neurosurgeon. The clinical presentation of the two groups was comparable. Overall outcome was assessed after a mean follow up period of between 19 and 37 months using the Ebeling classification. In addition, the effect of surgery on radicular pain, low back pain, and sensory and motor deficits was defined.Excellent to good results were achieved in 95% of the LTM group and 57% of the CIP group. The outcome was satisfactory to poor in 5% of the LTM and 43% of the CIP group (p0.004). The percentage of sensorimotor deficit and of radicular pain improvement was higher in the LTM group. New low back pain was found exclusively in the CIP group (21%). The complication rate was 5% in the LTM group and 11% in the CIP group.The LTM approach achieves a better overall outcome and improvement in radiculopathy. The complication rate is lower with the transmuscular route and the risk of new low back pain is minimised. These results are likely to be attributable at least in part to the lesser invasiveness of the LTM approach.

To compare the ablation volume, local tumour progression rate and complication rate of radiofrequency ablation (RFA) for small hepatocellular carcinomas (HCCs) using 15-G and 17-G single electrodes.This retrospective study was approved by the institutional review board and informed consent was waived. We reviewed percutaneous RFA cases for HCCs using 15-G or 17-G electrodes without multiple overlapping ablations. A total of 36 pairs of HCCs matched according to tumour size and active tip length were included. We compared ablation volume and complication rate between the two electrode groups. Cumulative local tumour progression rates were estimated using the Kaplan–Meier method and compared using the log-rank test.Tumour size and ablation time were not significantly different between the 15-G and 17-G groups (p50.661 and p50.793, respectively). However, ablation volume in the 15-G electrode group was larger than that in the 17-G group (14.465.4cm3 vs 8.762.5cm3; p,0.001). No statistical difference in complication rates between the two electrode groups was found. The 10- and 20-month local tumour progression rates were not significantly different between the two groups (2.8% and 5.6% vs 11.1% and 19.3%; p50.166).Ablation volume by the 15-G electrode was larger than that by the 17-G electrode. However, local tumour progression rate and complication rate were not significantly different between the two electrode groups.RFA of HCC using a 15-G electrode is useful to create larger ablation volumes than a 17-G electrode.

A new technique for dividing the fibula when performing a high tibial osteotomy is described. The head of the fibula is enucleated and morselized. The technique is simple and safe with a low complication rate.

BACKGROUND: The technical advantages in utilizing human acellular dermal matrix (ADM) products as pectoral extenders in immediate breast reconstruction with tissue expanders or implants are well documented in the medical literature. In this study, the authors examine a commonly used biologic xenograft product that has not yet been described in the medical literature for use in immediate breast reconstruction to determine whether a lower overall complication rate is identified compared to published data on ADM products. METHODS: A retrospective multicenter medical record review of data on 54 subjects in 93 tissue expander/implant-based, consecutive, immediate breast reconstructions from three surgeons at different institutions was performed in which Veritas® bovine pericardium was used as the biologic graft material for the pectoral extender. RESULTS: Over a 24-month period with an average of 11-month follow-up, complication rates using Veritas® in breast reconstruction for seroma formation (7.5 %), marginal skin flap necrosis (5.4 %) infection (6.5 %), and capsular contracture (0 %) were found to compare equally or favorably with statistically significant lower overall complications relative to one comparison study and lower rates of marginal skin flap necrosis relative to two comparison studies based upon previously published data from multisurgeon studies using ADM products. CONCLUSIONS: Overall complications were found to be lower with Veritas® than ADM products in comparable multisurgeon studies, though this was found to be statistically significant in only one comparison study. Level of Evidence: Level II, theraputic study.

Objective—To determine the rate of late complications following first implantation or elective unit replacement of a permanent pacemaker system. Design—Analysis of pacemaker data and complications prospectively acquired on a computerised database. Complications were studied over an 11 year period from January 1984 to December 1994. Setting—Tertiary referral cardiothoracic centre. Patients—Records of 2621 patients were analysed retrospectively. Main outcome measures—Complications requiring repeat procedures occurring more than six weeks after pacemaker implantation or elective unit replacement. Results—The overall rate of late complications was significantly lower after first implantation of a permanent pacemaker (34 cases, complication rate 1.4%, 95% confidence interval 0.9% to 1.9%) than after elective unit replacement (16 cases, complication rate 6.5% (3.3% to 9.7%). There were 20 cases of erosion, 18 infections, five electrode problems, and seven miscellaneous problems. Complications were more common with inexperienced operators (18.9% (6.0% to 31.8%)) than with experienced operators (0.9% (0.3% to 1.5%)). Conclusions—The incidence of late complications following pacemaker implantation is low and compares favourably with early complication rates. The majority are caused by erosion and infection. Patients who have undergone elective unit replacement are at particular risk. Keywords: permanent pacemaker; elective unit replacement; late complications; arrhythmias

The first trials of measles vaccines in the United Kingdom were reported in 1961 by Aldous et al., when three living attenuated vaccines derived from the Edmonston strain (Enders et al., 1960) were compared at the Fountain Hospital. In many cases vaccination reactions were too pronounced for the vaccines to be suitable for routine use. However, in view of the high complication rate of measles in young children (Miller, 1964), it was considered important to continue clinical trials of measles vaccine rendered less toxic by further attenuation. The present paper describes four subsequent trials of vaccines prepared from the Edmonston strain but which had undergone a further series of passages in chick-embryo or chick-cell tissue cultures. In some of the trials the vaccines were given alone, and in others concurrently with gamma-globulin.

Termination of pregnancy and laparoscopic sterilization has been performed in 101 women in a one-year period. The complication rate was low and the average stay in hospital was short. With close supervision and co-operation between the gynaecologist and the patient's general practitioner it is suggested that this is a safe and economic procedure.

A prospective study of vacuum aspiration in 400 cases of therapeutic abortion is described showing that the procedure was quick, involving little blood loss in most cases, and that the complication rate was low. The routine use of this method in therapeutic abortion is recommended.

Objective Injuries of the hand often require free flap reconstruction. To minimize flap loss, evidence exists to surgically syndactylize digits when repairing multiple injuries, with delayed flap division, or desyndactylization. However, evidence suggests that division of the flap at the time of inset can be accomplished with minimal negative effect. The purpose of this study was to evaluate outcomes, following hand reconstruction with free flaps utilizing either acute or staged desyndactylization techniques.Methods A systematic review utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was performed. Articles that described the use of a free flap for surgically syndactylized digits or multilobed flaps for coverage of multiple digits were included.Results One hundred sixty-one articles were reviewed with 34 fulfilling inclusion criteria. One hundred seventeen patients underwent 145 free flap reconstructions. Traumatic avulsions (49%) were the most common injuries, followed by burns (11%). Twenty-one (62%) papers described surgical syndactylization of digits, which were later desyndactylized and five (15%) papers included reconstruction of more than one digit with multilobed free flaps. Eight papers (24%) described both techniques. Overall, 100% of included flaps survived. Total complication rate was 6%, with six complications (67%) occurring in flaps with primary syndactylization.Conclusion Hand defects often require free flaps for reconstruction. Although free flaps for the reconstruction of digital defects is technically demanding, they result in better outcomes. With available evidence indicating complications rates less than those of staged desyndactylization, multidigit reconstruction with multilobed free flaps may be a more desirable technique.

Background: Leadless pacemakers (PMs) were recently introduced to address the complication rate of standard PMs with transvenous leads. Methods and Results: A 34-year old male with a history of intravenous substance abuse and a chronic type C hepatitis developed a complete atrioventricular block after cardiac surgery for infective endocarditis. Repeatedly, endo- and epi-cardially implanted PMs had to be explanted due to infection. A leadless MICRA pacemaker was successfully implanted with a dislocation into pulmonary artery several days after implantation. The PM was successfully retrieved using a single-loop retrieval snare guided by a steerable sheath. Subsequently, another Micra PM was successfully implanted with no further issues. Conclusion: In the case of a Micra leadless pacemaker dislocation, a conventional gooseneck snare in combination with a steerable sheath can be used to retrieve the device, improving the overall safety of leadless pacemakers.

Editor,—The paper by Walker and Brenchley1 highlights a crucial area of emergency medicine practice. The key issues are “How are skills maintained” and “What is an acceptable period of training”. The authors state in their conclusions that the majority of accident and emergency (A&E) consultants thought that rapid sequence induction (RSI) would be undertaken by A&E staff if an anaesthetist were unavailable. If the A&E staff are only performing this procedure rarely then they will become de-skilled and will have a higher complication rate than a colleague performing the procedure on a regular basis. Anaesthesia is defined as an essential secondment for training, why have this secondment if the skills are not going to be actively used. In order to be given the responsibility of “on call” the anaesthesia minimum requirement is three months of supervised training. I feel that it is no coincidence that this also is the length of our secondment. 1. ↵ Survey of the use of rapid sequence induction in the accident and emergency department. Walker A, Brenchley JJ.

Background Hump recurrence is a commonly encountered problem following dorsal preservation (DP) rhinoplasty when surgeons are learning the procedure. Objectives The aim of this paper was to compare the different methods for the prevention and treatment of dorsal problems following DP surgery. Methods One hundred and fifty primary rhinoplasty patients were included in our study. Their noses were classified in terms of both hump shape (V- or S-shaped) and height. All patients had a DP rhinoplasty by either a push-down (PD) or a let-down (LD) technique. The PD method was used for humps 4 mm. Follow-up evaluations were made with physical examination and photographs at 1 week, 3 months, and 12 months. Results Mean follow-up was 12.68 [1.78] months. Seventy-eight humps were V-shaped and 72 were S-shaped. PD was used for 67 cases, LD for 83 cases. Eight patients (5.3%, 8/150) had a visible dorsal hump problem after DP surgery. Based on their preoperative hump shape, 3 cases were V-shaped and 5 were S-shaped. All recurrent cases had a preoperative hump deformity >4 mm. The revision procedures were as follows: 4 patients had a PD procedure, 3 had a LD procedure, and 1 patient was treated by classic open resection rhinoplasty. Conclusions There is a correlation between preoperative hump height and eventual hump recurrence. The complication rate can be decreased with additional technical maneuvers and proper patient selection. Level of Evidence: 4

Introduction: Malignant Pleural Mesothelioma (MPM) is characterized by an aggressive behavior and an inevitably fatal prognosis, whose treatment is still far from being standardized. The role of surgery is questionable since a radical resection is unattainable in most cases. Hyperthermic IntraTHOracic Chemotherapy (HITHOC) combines the advantages of antitumoral effects together with those of high temperature on the exposed tissues with the aim to improve surgical radicality. Material and Methods: this is a narrative review on the role of HITHOC in the management of MPM patients. To provide data on the beginnings and the historical evolution of this technique, we searched the available literature by selecting the more exhaustive papers on this topic. Results: from 1994 to date different authors experimented HITHOC following a cytoreductive surgery in MPM, obtaining in most cases a good local control and a better overall survival associated to very low complication rate. Conclusions: HITHOC may be considered as a safe, feasible and effective procedure although there is a high heterogeneity between different protocols adopted worldwide. More structured studies are needed to reach a unanimous consensus on this technique.

ObjectiveTo study short-term (DesignSystematic review.MethodsThe systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed and EMBASE were searched for relevant papers on 11 June 2019 and rerun on 27 May 2020. Studies reporting complications, reoperations, length of stay and mortality within 90 days were included. Studies were reviewed according to criteria from the Oxford Centre for Evidence-Based Medicine and the quality of evidence was assessed using the Newcastle–Ottawa Scale.ResultsThe search retrieved 1957 articles. Sixty-six articles were included. The quality of evidence was poor to good. Most studies were retrospective, and no randomised clinical trials were identified. Of included studies a median of 6 Martin criteria for reporting complications after surgery were fulfilled. The Clavien-Dindo classification for grading complications was most frequently used. The weighted overall complication rate after RC was 34.9% (range 28.8–68.8) for in-house complications, 39.0% (range 27.3–80.0) for 30-day complications and 58.5% (range 36.1–80.5) for 90-day complications. The most common types of complications reported were gastrointestinal (29.0%) and infectious (26.4%). The weighted mortality rate was 2.4% (range 0.9–4.7) for in-house mortality, 2.1% (0.0–3.7) for 30-day mortality and 4.7% (range 0.0–7.0) for 90-day mortality. Age and comorbidity were identified as the best predictors for complications following RC.ConclusionShort-term morbidity and mortality are high following RC. Reporting of complications is heterogeneous and the quality of evidence is generally low. There is a continuous need for randomised studies to address any intervention that can reduce morbidity and mortality following RC.PROSPERO registration number104937.

A short cut review was carried out to establish whether the seldinger "over the wire" technique is better than other techniques of pneumothorax drainage. Altogether 28 papers were found using the reported search, of which three presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these best papers are tabulated. A clinical bottom line is stated.
