Totally laparoscopic right hemicolectomy with intracorporeal anastomosis is a technically and oncologically safe procedure

Abstract

Background: During laparoscopic right hemicolectomy, most surgeons perform an extracorporeal anastomosis. A totally laparoscopic procedure with intracorporeal anastomosis may improve cosmesis because midline- or paraumbilical incisions can be avoided. Here, we investigate the safety of an intracorporeal anastomosis from a technical and oncological perspective.

Methods: All patients who underwent right hemicolectomy with intracorporeal anastomosis between 2003-2011 were retrospectively analyzed. Parameters were duration of surgery, intraoperative blood loss, mortality and morbidity. Adequacy of oncologic resections was scored by resectional margins and number of harvested lymph nodes.

Results: A total of 162 patients were included with a median age of 69 years (IQR60-76). The duration of surgery was 100 minutes (80-120) and intraoperative blood loss was 30 mL (10-100). Hundred-twenty patients (74%) underwent an oncologic resection. Number of harvested lymph nodes was 12 (9-18). RO-resection was achieved in 100%. Four patients died (2.5%). Postoperative complications were: anastomotic leakage (3.1%; n = 5), ileus (4.9%; n = 8), abscesses (2.5% ; n = 4), wound infection (3.1% ; n = 5) and cardiopulmonary complications (10.5% ; n = 17). Duration of oncological follow-up was 2.5 years (1.3-4.6). Local recurrence and overall survival rates at two years were 0.8% and 85.4%, respectively.

Conclusion: Right hemicolectomy with intracorporeal anastomosis is a technically and oncologically safe procedure with acceptable operating time and low mortality.
