INTRODUCTION: Single incision laparoscopic (SIL) surgery is a laparoscopic procedure which leaves a single small incision in navel, and has been reported to be less invasive than and as safe and efficient as the conventional multiport laparoscopic (MPL) surgery. The long-term rate of incisional hernia after SILS colectomy is unknown, and the risk factors of incisional hernia formation is not fully elucidated.
METHODS and PROCEDURES: This is a retrospective from a prospectively collected database. The investigation took place in a high-volume multidisciplinary tertiary private hospital in Japan. The patients who had elective SIL colectomy without conversion to open/ MPL or ileo/colostomy from 2009 to 2015 were included.
RESULTS: 661 patients were included with a median follow-up of 1094 (range 120- 1806) days. 55 patients (8.3%) were diagnosed as incisional hernia, and the median interval from operation to the diagnosis was 329 (120-1806) days. On univariate analyses, age> 70 years (P=0.0364), ASA PS=/> 3 (P=0.0454), BMI > 25 (P<0.0001), depth of abdominal wall a the umbilical level> 20mm (P=0.0079), thorough lymph node dissection (P=0.0348) were risk factors, but other factors; gender, the history of smoking, diabetes mellitus, pre-operative prognostic nutritional index, tumor size, incisional length, operation time, operation mode or superficial surgical site infection were not statistically significant. On multivariate analyses, BMI > 25 (P=0.0002) was the risk factor of incisional hernia.
CONCLUSIONS: The incidence rate of incisional hernia after SIL colectomy was within permissible range, and high BMI was its risk factor.
