BACKGROUND Limited data exist on the use of peroral endoscopic myotomy (POEM) for therapy of spastic esophageal disorders (SEDs). OBJECTIVE To study the efficacy and safety of POEM for the treatment of patients with diffuse esophageal spasm, jackhammer esophagus, or type III (spastic) achalasia. DESIGN Retrospective study. SETTING International, multicenter, academic institutions. PATIENTS All patients who underwent POEM for treatment of SEDs refractory to medical therapy at 11 centers were included. INTERVENTIONS POEM. MAIN OUTCOME MEASUREMENTS Eckardt score and adverse events. RESULTS A total of 73 patients underwent POEM for treatment of SEDs (diffuse esophageal spasm 9, jackhammer esophagus 10, spastic achalasia 54). POEM was successfully completed in all patients, with a mean procedural time of 118 minutes. The mean length of the submucosal tunnel was 19 cm, and the mean myotomy length was 16 cm. A total of 8 adverse events (11%) occurred, with 5 rated as mild, 3 moderate, and 0 severe. The mean length of hospital stay was 3.4 days. There was a significant decrease in Eckardt scores after POEM (6.71 vs 1.13; P = .0001). Overall, clinical response was observed in 93% of patients during a mean follow-up of 234 days. Chest pain significantly improved in 87% of patients who reported chest pain before POEM. Repeat manometry after POEM was available in 44 patients and showed resolution of initial manometric abnormalities in all cases. LIMITATIONS Retrospective design and selection bias. CONCLUSION POEM offers a logical therapeutic modality for patients with SEDs refractory to medical therapy. Results from this international study suggest POEM as an effective and safe platform for these patients.

Background and study aims: Type III achalasia is characterized by rapidly propagating pressurization attributable to spastic contractions. Although laparoscopic Heller myotomy (LHM) is the current gold standard management for type III achalasia, peroral endoscopic myotomy (POEM) is conceivably superior because it allows for a longer myotomy. Our aims were to compare the efficacy and safety of POEM with LHM for type III achalasia patients. Patients and methods: A retrospective study of 49 patients who underwent POEM for type III achalasia across eight centers were compared to 26 patients who underwent LHM at a single institution. Procedural data were abstracted and pre- and post-procedural symptoms were recorded. Clinical response was defined by improvement of symptoms and decrease in Eckardt stage to ≤ 1. Secondary outcomes included length of myotomy, procedure duration, length of hospital stay, and rate of adverse events. Results: Clinical response was significantly more frequent in the POEM cohort (98.0 % vs 80.8 %; P = 0.01). POEM patients had significantly shorter mean procedure time than LHM patients (102 min vs 264 min; P < 0.01) despite longer length of myotomy (16 cm vs 8 cm; P < 0.01). There was no significant difference between POEM and LHM in the length of hospital stay (3.3 days vs 3.2 days; P = 0.68), respectively. Rate of adverse events was significantly less in the POEM group (6 % vs 27 %; P < 0.01). Conclusions: POEM allows for a longer myotomy than LHM, which may result in improved clinical outcomes. POEM appears to be an effective and safe alternative to LHM in patients with type III achalasia.

AIM To evaluate the efficacy and safety of the laparoscopic approaches for parastomal hernia repair reported in the literature. METHODS A systematic review of PubMed and MEDLINE databases was conducted using various combination of the following keywords: stoma repair, laparoscopic, parastomal, and hernia. Case reports, studies with less than 5 patients, and articles not written in English were excluded. Eligible studies were further scrutinized with the 2011 levels of evidence from the Oxford Centre for Evidence-Based Medicine. Two authors reviewed and analyzed each study. If there was any discrepancy between scores, the study in question was referred to another author. A meta -analysis was performed using both random and fixed-effect models. Publication bias was evaluated using Beggs funnel plot and Eggers regression test. The primary outcome analyzed was recurrence of parastomal hernia. Secondary outcomes were mesh infection, surgical site infection, obstruction requiring reoperation, death, and other complications. Studies were grouped by operative technique where indicated. Except for recurrence, most postoperative morbidities were reported for the overall cohort and not by approach so they were analyzed across approach. RESULTS Fifteen articles with a total of 469 patients were deemed eligible for review. Most postoperative morbidities were reported for the overall cohort, and not by approach. The overall postoperative morbidity rate was 1.8% (95%CI: 0.8-3.2), and there was no difference between techniques. The most common postoperative complication was surgical site infection, which was seen in 3.8% (95%CI: 2.3-5.7). Infected mesh was observed in 1.7% (95%CI: 0.7-3.1), and obstruction requiring reoperation also occurred in 1.7% (95%CI: 0.7-3.0). Other complications such as ileus, pneumonia, or urinary tract infection were noted in 16.6% (95%CI: 11.9-22.1). Eighty-one recurrences were reported overall for a recurrence rate of 17.4% (95%CI: 9.5-26.9). The recurrence rate was 10.2% (95%CI: 3.9-19.0) for the modified laparoscopic Sugarbaker approach, whereas the recurrence rate was 27.9% (95%CI: 12.3-46.9) for the keyhole approach. There were no intraoperative mortalities reported and six mortalities during the postoperative course. CONCLUSION Laparoscopic intraperitoneal mesh repair is safe and effective for treating parastomal hernia. A modified Sugarbaker approach appears to provide the best outcomes.

BACKGROUND Surgeons play a crucial role in the cost efficiency of the operating room through total operative time, use of supplies, and patient outcomes. This study aimed to examine the effect of surgeon education on disposable supply usage during laparoscopic cholecystectomy. METHODS Surgeons were educated about the cost of disposable equipments without incentives for achieved cost reductions. Surgical supply costs for laparoscopic cholecystectomy in fiscal year (FY) 2013 were compared with FY 2014. RESULTS The average disposable supply cost per laparoscopic cholecystectomy was reduced from

531 (n = 428) in FY 2014, representing a 10% reduction in supply costs (P < .001). Adjustments included reduction in the use of expensive fascial closure devices, clip appliers, suction irrigators, and specimen retrieval bags. CONCLUSIONS Disposable equipment cost for laparoscopic cholecystectomy can be reduced by surgeon education. These techniques can likely be used to reduce costs in an array of specialties and procedures.

BACKGROUND: Surgeon instrument choices are influenced by training, previous experience, and established preferences. This causes variability in the cost of common operations, such as laparoscopic appendectomy. Many surgeons are unaware of the impact that this has on healthcare spending. OBJECTIVE: We sought to educate surgeons on their instrument use and develop standardized strategies for operating room cost reduction. DESIGN: We collected the individual surgeon instrument cost for performing a laparoscopic appendectomy. Sixteen surgeons were educated about these costs and provided with cost-effective instruments and techniques. SETTINGS: This study was conducted in a university-affiliated hospital system. PATIENTS: Patients included those undergoing a laparoscopic appendectomy within the hospital system. MAIN OUTCOME MEASURES: Patient demographics, operating room costs, and short-term outcomes for the fiscal year before and after the education program were then compared. RESULTS: During fiscal year 2013, a total of 336 laparoscopic appendectomies were performed compared with 357 in 2014. Twelve surgeons had a ≥5% reduction in average cost per case. Overall, the average cost per case was reduced by 17% (p < 0.001). Switching from an energy device to a stapler load or reusable plastic clip applier resulted in the largest savings per case at

442 per case. There were no differences in length of stay, 30-day readmissions, postoperative infections, operating time, or reoperations. LIMITATIONS: This retrospective study is subject to the accuracy of the medical chart system. In addition, specific instrument costs are based on our institution contracts and vary compared with other institutions. CONCLUSIONS: In this study we demonstrate that operative instrument costs for laparoscopic appendectomy can be significantly reduced by informing the surgeons of their operating room costs compared with their peers and providing a low-cost standardized instrument tray. Importantly, this can be realized without any incentive or punitive measures and does not negatively impact outcomes. Additional work is needed to expand these results to more operations, hospital systems, and training programs.

BACKGROUND Our aim was to determine the impact of surgeon education regarding disposable supply costs to reduce intraoperative costs for a common procedure such as inguinal hernia repair. STUDY DESIGN At the end of the 2013 fiscal year (FY 13), surgeons in our department were provided with information about the cost of disposable equipment and implants used in common general surgery operations. Surgeons who historically had lower supply costs demonstrated individual techniques to their colleagues. No financial incentive or punitive measures were used to encourage behavior change. Surgical supply costs for laparoscopic and open inguinal hernia repair in FY13 were then compared with costs during fiscal year 2014 (FY14) using Mann-Whitney U tests. RESULTS The average cost of laparoscopic inguinal hernia repairs decreased from an average
