Peritonitis: 10 years' experience in a single surgical unit.

BACKGROUND: Peritonitis secondary to gut perforation is still one of the commonest surgical emergencies in India and is associated with high morbidity and mortality. The present study examines the aetiology and outcome of peritonitis cases operated on in our surgical unit, and compares our findings with those of previous studies performed between 1981 and 1991. METHOD: A retrospective study of 260 peritonitis patients operated on in a single surgical unit from 1995 to 2006 was done and data involving clinical presentation, operative findings and post-operative course were studied and analysed. RESULTS: Causes of peritonitis were small bowel perforation (96 ileal, 17 jejunal), peptic perforation (45 duodenal, 16 gastric), appendicular perforation (36), primary peritonitis (8), and others (42). The incidence of major complications was 25% (burst-11%, leak-5%, intraabdominal abscess-5%, multi-organ failure-6.5%). The overall mortality was 10%. High mortality was observed in jejunal, gall bladder and liver abscess perforation cases (> 20%). Histopathological evaluation (143 specimens) revealed tuberculosis in 42 (mostly small bowel), malignancy in 8, and inflammation in the rest. Comparisons with a similar study carried out in the same unit and published in 1995 revealed similar demographic features and mortality, but a change in the most common cause (peptic ulcer perforation to small bowel perforation), and an increased performance of enterostomy compared with primary repair in small bowel perforation and a decrease in the leak rate (13% to 4%). CONCLUSION: Small bowel perforation is the commonest form of perforation and the mortality rate associated with peritonitis remains unchanged.

Mycetoma sans sinuses.

Mycetoma is a chronic suppurative infection involving the skin, subcutaneous tissue and bone. The hallmark of mycetoma is tumefaction, draining sinuses and the presence of microcolonies called grains. Sinuses develop in all patients with mycetoma within a year of the appearance of the lesion. The following case is reported as no sinuses had developed despite the presence of the lesion for 9 years, posing a diagnostic dilemma.

Agenesis of the Gallbladder: Falacies of Ultrasonography

A case of the agenesis of gallbladder detected at laparotomy for symptomatoloy suggestive of gallbladder disease is described. The agenesis of gallbladder, diagnostic inaccuracies and fallacies of ultrasonography for gallbladder disease are discussed. The diagnosis of agenesis was substantiated on MRCP, done postoperatively.

Primary Torsion of the Omentum in Children

Torsion of the omentum is an uncommon cause of abdominal pain in children. The patient usually presents with a clinical picture simulating acute appendicitis. We report on two children with primary omental torsion, who were managed by partial omentectomy with a satisfactory outcome in each case.
