Abstract

Nowadays the majority of appendectomies are undertaken laparoscopically. The associated per and postoperative complications are well established and known. However, some rare postoperative complications continue to be reported such as small bowel volvulus. We report the case of 44-year-old women who developed a small bowel obstruction from acute small bowel volvulus due to an early postoperative flanges five days after a laparoscopic appendectomy

Introduction

Acute appendicitis is one of the most common surgical emergencies requiring acute hospital admission. Nowadays the majority of appendectomies are undertaken laparoscopically, with evidence demonstrating reduced post-operative pain, a lower rate of wound infection, faster recovery and shorter hospital stay when compared with the open procedure. It’s associated per and post-operative complications are well established and known. However, some rare post-operative complications continue to be reported such as small bowel volvulus. Herein we report the case of small bowel volvulus after laparoscopic appendectomy.

Case Report

We report the case of 44-year-old women who developed a small bowel obstruction from acute small bowel volvulus due to an early post-operative flanges five days after a laparoscopic appendectomy. The patient past medical history included hypothyroidism under treatment and no previous surgeries. She was admitted in the surgery department with a history of acute abdominal pain associated with vomiting and fever. Physical exam showed tenderness in the right iliac fossa. We completed by blood test and CT scan and the diagnosis of acute appendicitis was retained. Laparoscopic appendectomy was performed. Three trocars were used. The appendix was gangrenous and perforated. The base of the appendix was ligated and the appendix was then divided with scissors. The peritoneal cavity was then irrigated with normal saline until clear fluid was aspirated from the abdominal cavity. The course was marked initially by good evolution with disappearance of the fever and transit restored as gas associated with well tolerance of the diet. But at day four post-operative the patient presented an acute abdominal pain associated with vomiting. Physical examination revealed that her abdomen was slightly distended and rigid with tenderness. Abdominal radiograph displayed multiple air-fluid levels in the small intestine. Computed tomography demonstrated a typical whirlpool sign in favor of closed loop bowel obstruction.

With her abdominal distension and tenderness progressively worsening, emergency laparotomy was performed with a midline incision.

Per operatively we found a stigma of the small intestine volvulated on a loose small bowel flange with distension of the intestine upstream. Otherwise, the small bowel viability was good, the coecum and the appendectomy staple were in place. The course was marked then by good evolution and the patient was discharged at day three post-operative.

Discussion

Closed loop small bowel obstruction is a form of mechanical obstruction in which two or more points along the course of the bowel are obstructed at a single constrictive lesion. It has a high mortality rate if the correct diagnosis and subsequent laparotomy are delayed. Small bowel obstruction due to intestinal volvulus following laparoscopic procedures is a rare but documented complication such as the case of our patient. In the following table we report all the cases of small bowel volvulus after laparoscopic appendectomy that have been reported in literature so far.

As our case involved a small bowel volvulus, we focused on the etiology of this particular form of volvulus after laparoscopic appendectomy.it seems important to mention that there was other form of volvulus that were reported such as coecum, or sigmoid volvulus. For the most cases reported in literature the cause of the volvulus was due surgical staple. Postoperative adhesions may create an axis around which the cecum or small bowel can rotate such as the case of our patient. The particularity of this case was the early post-operative adhesion associated with the volvulus.

In the eight documented cases of intestinal volvulus following the laparoscopic appendectomy, there was an interval procedure-presentation of volvulus ranging between 24 hours and 10 days, in the case of our patient it was four days. Although there are few reports of a successful resolution of intestinal volvulus without surgical intervention, it is generally agreed that, in most cases, operative management is required [11].

Conclusion

Despite its large use laparoscopy procedure is not without risks. This case is a new addition to the wide range of reported complications observed after laparoscopic procedures, such as the appendectomy. After the exclusion of more common complications, the gut volvulus should be considered when these patients deteriorate postoperatively.
