Abstract

Purpose: Routine use of abdominal drain or prolonged antibiotic prophylaxis is no longer part of current clinical practice in colorectal surgery. Nevertheless, in patients undergoing laparoscopic right hemicolectomy with intracorporeal anastomosis (ICA), it may reduce perioperative abdominal contamination. Furthermore, in cancer patients, prolonged surgery with extensive dissection such as central vascular ligation and complete mesocolon excision with D3 lymphadenectomy (altogether radical right colectomy RRC) is called responsible for affecting postoperative ileus. The aim was to evaluate postoperative resumption of gastrointestinal functions in patients undergoing right hemicolectomy for cancer with ICA and standard D2 dissection or RRC, with or without abdominal drain and prolonged antibiotic prophylaxis.

Methods: Monocentric factorial parallel arm randomized pilot trial including all consecutive patients undergoing laparoscopic right hemicolectomy and ICA for cancer, in 20 months. Patients were randomized on a 1:1:1 ratio to receive abdominal drain, prolonged antibiotic prophylaxis or neither (I level), and 1:1 to receive RRC or D2 colectomy (II level). Patients were not blinded. The primary aim was the resumption of gastrointestinal functions (time to first gas and stool, time to tolerated fluids and food). Secondary aims were length of stay and complications' rate.

Clinicaltrials: gov no. NCT04977882.

Results: Fifty-seven patients were screened; according to sample size, 36 were randomized, 12 for each arm for postoperative management, and 18 for each arm according to surgical techniques. A difference in time to solid diet favored the group without drain or antibiotic independently from standard or RRC. Furthermore, when patients were divided with respect to surgical technique and into matched cohorts, no differences were seen for primary and secondary outcomes.

Conclusion: Abdominal drainage and prolonged antibiotic prophylaxis in patients undergoing right hemicolectomy for cancer with ICA seem to negatively affect the resumption of a solid diet after laparoscopic right hemicolectomy with ICA for cancer. RRC does not seem to influence gastrointestinal function recovery.
