Purpose
To delineate the learning curve (LC) for laparoscopic appendectomy (LA) performed by residents according to seniority in training.
Methods
Between October 2015 and November 2016, 150 patients underwent LA by three residents (in their first, second, and third year of training) under supervision. The patients were non-randomly assigned to each resident. The data were reviewed and analyzed retrospectively from prospectively collected database. The perioperative outcomes were compared between the three residents including operation time, complication, conversion, and so on. The LCs were evaluated by the moving average method and cumulative sum control chart (CUSUM) for operation time and surgical completion.
Results
Baseline characteristics and perioperative outcomes were similar except for age and location of the appendix among the three groups. Operation time was not different among the three residents (43.9, 45.3, and 48.4 min for A, B, and C, respectively). The moving average method for operation time showed a decreasing tendency for all residents. CUSUM for operation time showed that the peak points occurred at the 24th, 18th, and 31st cases for resident A, B, and C, respectively. In terms of surgical failure, residents A, B, and C reached steady states after the 35th, 11th, and 16th cases, respectively. Perforation of the appendix base was the only risk factor for surgical failure.
Conclusion
The LC for LA by residents was 11-35 cases according to multidimensional statistical analyses. The accumulation of surgical experience of residents might affect the LC, especially for surgical completion rather than for operation time.

Purpose
Stoma takedown is a frequently performed procedure with considerable postoperative morbidities. Various skin closure techniques have been introduced to reduce surgical site infections. The aim of this study was to assess postoperative outcomes after stoma takedown during a long-term follow-up period.
Methods
Between October 2006 and December 2015, 84 consecutive patients underwent a colostomy or ileostomy takedown at our institution. Baseline characteristics and perioperative outcomes were analyzed through retrospective reviews of medical records.
Results
The proportion of male patients was 60.7%, and the mean age of the patients was 59.0 years. The overall complication rate was 28.6%, with the most common complication being prolonged ileus, followed by incisional hernia, anastomotic leakage, surgical site infection, anastomotic stenosis, and entero-cutaneous fistula. The mean follow-up period was 64.3 months. The univariate analysis revealed no risk factors related to overall complications or prolonged ileus.
Conclusion
The postoperative clinical course and long-term outcomes following stoma takedown were acceptable. Stoma takedown is a procedure that can be performed safely.
