Analysis of variables related to morbidity and mortality of the ileocolic anastomosis after right hemicolectomy

Abstract

Introduction: Right hemicolectomy with ileocolic anastomosis is a frequent surgery with many ways to perform it.

Objective: To evaluate which is the best ileocolic anastomosis in terms of morbidity and mortality and to make a comparative evaluation of the postoperative clinical evolution according to the type of anastomosis.

Patients and Method: Analytical observational study, with defined inclusion and exclusion criteria. The variables to be studied are divided into two groups, those related to the surgical technique and its anastomotic configuration, and the variables related to the results of the surgical intervention, creating a contingency table that crosses the data. Data analysis with STATA 13.0.

Results: 216 patients with ileocolic anastomosis, highlighting statistical significance when crossing: A) reoperation and type of suture (p = 0.044), with UN or 3.4 (95% CI 0.94 to 18.6), being of greater risk the mechanics; B) mortality and urgency (p = 0.001) with an OR 7.76 (95% CI 1.56-49.29), with emergency surgery being of greater risk. Isoperistaltic anastomosis with gas elimination (p < 0.001), intestinal transit (p = 0.009) and solid intake (p = 0.005) earlier. There is earlier expulsion of gases in the laparoscopic approach, manual suture, end-to-side and isoperistaltic of the anastomosis and elective surgery.

Conclusion: There is great variability of techniques to perform the ileocolic anastomosis. Manual anastomosis is less likely to require surgical reoperation, elective surgery has a lower mortality than that of emergency surgery. We suggest performing it laparoscopically, with manual suture, lateral term, isoperistaltic and electively, for having a shorter recovery.
