Abstract
BackgroundAlthough a larger proportion of colorectal surgeries have been performed laparoscopically in the last few years, a steep learning curve prevents us from considering laparoscopic colorectal surgery as the gold standard technique for treating disease entities in the colon and rectum. The purpose of this single centre study was to determine, using various parameters and following a well-structured and standardized surgical procedure, the adequate number of cases after which a single surgeon qualified in open surgery but with no previous experience in laparoscopic colorectal surgery and without supervision, can acquire proficiency in this technique.MethodsFrom 2012 to 2019, 112 patients with pathology in the rectum and colon underwent laparoscopic colorectal resection by a team led by the same surgeon. The patients were divided into two groups (group A:50 – group B:62) and their case records and histopathology reports were examined for predefined parameters, statistically analysed and compared between groups.ResultsThere was no significant difference between groups in the distribution of conversions (p = 0.635) and complications (p = 0.637). Patients in both groups underwent surgery for the same median number of lymph nodes (p = 0.145) and stayed the same number of days in the hospital (p = 0.109). A statistically important difference was found in operation duration both for the total (p = 0.006) and for each different type of colectomy (sigmoidectomy: p = 0.026, right colectomy: p = 0.013, extralevator abdominoperineal resection: p = 0.050, low anterior resection: p = 0.083).ConclusionsTaking into consideration all the parameters, it is our belief that a surgeon acquires proficiency in laparoscopic colorectal surgery after performing at least 50 diverse cases with a well structured and standardized surgical procedure.

From October 2012 to January 2019, 112 patients with pathology in the rectum and colon underwent laparoscopic colorectal resection at a regional general hospital (Venizeleio General Hospital of Heraklion in Crete), performed by a team led by the same surgeon (M.C.), who qualified for open surgery (> 300 colectomies) but had no previous experience with advanced laparoscopic procedures
Summary
A larger proportion of colorectal surgeries have been performed laparoscopically in the last few years, a steep learning curve prevents us from considering laparoscopic colorectal surgery as the gold standard technique for treating disease entities in the colon and rectum. The purpose of this single centre study was to determine, using various parameters and following a well-structured and standardized surgical procedure, the adequate number of cases after which a single surgeon qualified in open surgery but with no previous experience in laparoscopic colorectal surgery and without supervision, can acquire proficiency in this technique. The main reason for this lower percentage is the steep and long-term learning curve of laparoscopic colorectal surgery [15, 16]
