Circular Mini-Incision in the Left Iliac Fossa Followed by Purse-String Closure as a Minimally Invasive Approach for the Sigmoid Volvulus: A Technical Note.

Abstract

Introduction: Volvulus of the sigmoid is a common cause of intestinal obstruction in Morocco. It is a serious condition with substantial mortality. Initial endoscopic decompression followed by resection of the redundant colon via laparotomy or laparoscopy is the procedure of choice. Exteriorization of the sigmoid colon through a linear skin incision in the left iliac fossa has been described as an alternative approach for the classic midline incision, with or without laparoscopic assistance, with acceptable results.Methods: We describe herein a novel, minimally invasive approach for fit patients with non-complicated volvulus sigmoid. This approach consists of a skin-disk incision in the left iliac fossa, exteriorization of the redundant colon, and resection with or without primary anastomosis, followed by a purse-string closure.Results: A 65-year-old patient with no prior notable medical history, presented to the emergency department with his first episode of sigmoid volvulus. A skin-disk incision was made in the left iliac fossa, exteriorization of the sigmoid was done easily through the incision, and resection and manual anastomosis were done. The closure was made in a purse-string fashion. Recovery was uneventful and the patient was discharged home on the fourth postoperative day. No wound infection was noted and the cosmetic result was satisfactory.Conclusion: Left iliac skin-disk incision followed by a purse-string closure is an option for approaching the abdomen in the case of sigmoid volvulus. It has been demonstrated that this technique helps reduce wound-related complications in patients undergoing stoma reversal. Authors suggest that cosmetic results are better and the incidence of surgical site infection can be lower with this technique as compared to the classic linear skin incision. Results, however, should be confirmed by larger studies.
