Intracorporeal Versus Extracorporeal Ileocolic Anastomosis in Laparoscopic Right Hemicolectomy: Leakage Rate

Abstract

Context: Colorectal carcinoma is among the common cancers that affect people in western countries, and the incidence was approximated at 1.36 million cases globally in 2012. A right hemicolectomy is a routine procedure for right-sided colonic cancer. Currently, laparoscopic-assisted right hemicolectomy is typically performed using the extracorporeal anastomotic method. However, despite the inception of laparoscopic surgery and advanced recovery techniques for colorectal surgery, morbidity rates remain considerable. Evidence Acquisition: The literature was systematically analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. In-depth research was conducted using Embase and PubMed’s bibliographic data sources with the help of a medical librarian. Studies that were eligible were randomized controlled trials, human research, or comparative studies on intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy Results: A total of 2694 studies were initially obtained. From them, 14 non-randomized comparative academic works were eligible for inclusion in the assessment, with a total of 1494 patients. We found that intracorporeal anastomosis in laparoscopic right hemicolectomy is associated with minimized short-range morbidity as well as a shorter hospital stay. However, we identified an absence of a remarkable difference for anastomotic leakage between the intra- and the extra-corporeal techniques. Conclusions: Our systematic evaluation indicates no notable difference in the rate of discharge between intracorporeal anastomosis and extracorporeal anastomosis in laparoscopic right hemicolectomy. However, randomized controlled trials are required to confirm the discovery made by this study.
