BACKGROUND The advent of single incision laparoscopic surgery has brought renewed attention to cholecystectomy due to the promise of improved cosmesis and less parietal trauma. Small series have demonstrated the feasibility of single incision laparoscopic cholecystectomy (LC). Our series adds to the literature by demonstrating a variety of ancillary techniques that may be employed to perform single incision LC safely, and compares our early experience with that of our standard LC. METHODS We performed a retrospective chart review of patients who underwent single incision LC between February 2008 and April 2009. These patients were compared with an equal number of randomly selected patients undergoing LC during the same period. We identified 25 attempted single incision LC, which were included in our analysis. RESULTS Single incision LC was successfully performed in 21 patients, with only 4 patients requiring conversion to LC. No patients in either group had acute cholecystitis. The critical view of safety was documented in 20 of 21 patients undergoing a successful single incision LC compared with all patients undergoing LC. Operative time was significantly longer in the single incision group. Complications were minor and comparable between the 2 groups. In 9 patients (43%), a suture passer helped to retract the gallbladder. In 8 patients (38%), 1 or 2 Prolene sutures placed by means of a Keith needle helped to retract the gallbladder over the liver and/or helped to retract the infundibulum. In 2 patients, ≥1 supplemental 5-mm port was utilized. In 5 patients (24%), no supplementary retraction was necessary. CONCLUSION Single incision LC is technically more challenging than LC, but can be performed safely by experienced laparoscopic surgeons with results comparable with LC.

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 To evaluate resident case volume after discontinuation of a laparoscopic surgery fellowship, and to examine disparities in patient care over the same time period. METHODS Resident case logs were compared for a 2-year period before and 1 year after discontinuing the fellowship, using a 2-sample t test. Databases for bariatric and esophageal surgery were reviewed to compare operative time, length of stay (LOS), and complication rate by resident or fellow over the same time period using a 2-sample t test. RESULTS Increases were seen in senior resident advanced laparoscopic (Mean Fellow Year = 21 operations vs Non Fellow Year = 61, P < 0.01), esophageal (1 vs 11, P < .01) and bariatric volume (9 vs 36, P < .01). Junior resident laparoscopic volume increased (P < 0.05). No difference in LOS or complication rate was seen with resident vs fellow assistant. Operative time was greater for gastric bypass with resident assistant (152 ± 51 minutes vs 138 ± 53, P < .05). CONCLUSION Discontinuing a laparoscopic fellowship significantly increases resident case volume in laparoscopic surgery. Operative time for complex operations may increase in the absence of a fellow. Other patient outcomes are not affected by this change.

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
