Abstract

We report a case of perforated multiple sigmoid diverticulitis presented within 8 hours with symptoms similar to those of acute appendicitis.


Introduction

Diverticula arise at the points where the vessels enter the colonic wall between two equidistant longitudinal bands, a weak site where the mucosal layer herniates through the muscularis towards the serosa. Consequently, the diverticular wall does not contain a muscular layer. Diverticula formation is related to a long-standing low-fiber diet associated with abnormalities in colonic motility and raised intraluminal pressure1.

Most frequently colonic diverticula are located distally on the sigmoid colon alone (26%) or involving both the sigmoid and descending colon (30%). However, sometimes they are scattered throughout the colon (16%) or are limited to the caecum and ascending colon (less than 5% of the cases)1.

Right-sided diverticulitis presents with symptoms similar to those of acute appendicitis. Thus, right-sided diverticulitis remains a diagnostic dilemma2. We report a case of perforated sigmoid diverticulitis mimicking acute appendicitis.

Case Report

A 63-year-old man presented with an 8 hour history of central abdominal pain which later localized to the right iliac fossa. There was neither significant past medical history nor an abdominal surgery.

Clinical examination revealed a temperature of 38°C, with local peritonism in the right iliac fossa. The white blood cell count was 18.3 x 103/µl with 92.8% neutrophils. Electrolytes were normal, as were liver functions, lactate dehydrogenase and creatin phosphokinase. The abdominal plain roentgenogram was normal. As detecting free fluid in the abdominal cavity at the abdominal ultrasonographic examination, an emergency operation planed.

During the operation, no free gas but nearly 100cc of pyoid fluid was found in the abdominal cavity and we observed multiple colonic diverticulas along the whole large bowel and a nearly 15 cm long area of multiple perforated sigmoid diverticulitis at the 50 cm proximal of the rectosigmoidal junction (Fig.1). Then the patient treated by the afflicted bowel segment resection and closure of the rectal stump (Hartmann's procedure).

Pathology confirmed the diagnosis. The pathologist reported neither ulcerative colitis nor crohn disease. The patient has been discharged healthily at sixth day after the operation.

Discussion

Perforation is the most frequent complication of diverticular disease requiring surgical treatment. Because it is preceded by local inflammation, in most of the cases the perforated contents are walled of by adherent pericolic structures leading to a pericolic abscess. Free perforation occurs rarely and results in diffuse peritonitis, sepsis and shock3. At our case the clinical presentation prevented the septic progress.

Nowadays, in patients with complicated sigmoid diverticula the entire sigmoid colon must be removed and the anastomosis constructed between the descending colon and the rectum4. Alternatively, a two-stage procedure like Hartmann's resection or primary resection with anastomosis and proximal colostomy may be performed in selected cases, especially in patients with substantial fecal contamination and inflammation1,4. For instance, in cases with free diverticular perforation and generalized peritonitis Hartmann's resection is considered to be the procedure of choice4.

Right-sided diverticulitis presents with symptoms similar to those of acute appendicitis. However, at our case, perforated multiple sigmoid diverticulitis presented within 8 hours with symptoms similar to those of acute appendicitis.
