Background: Although in the last few years a larger proportion of colorectal surgeries have been performed laparoscopically, 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 center study is to determine, using various parameters and following a well structured and standardised surgical procedure, the adequate number of cases after which a single

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 analyzed and compared between groups.Results: There was no significant difference between groups in the distribution of conversions (p=0.635) and complications (p=0.637). Patients in both groups were operated for the same median number of lymph nodes (p=0.145) and stayed the same number of days in hospital (p=0.109). A statistically important difference was found in operation duration both in 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).Conclusions: Taking 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 standardised surgical procedure.
