Abstract

Introduction and importance: Sigmoid volvulus, an instead identified case of bowel obstruction, is defined as twisting a segment of sigmoid around its mesentery. Despite Western countries in which sigmoid volvulus affects the elderly, in volvulus belt countries, it is a disorder of predominantly men in their 4th decade of life. Case presentation: A 52-year-old woman presented with 4 days of abdominal distension and constipation. Physical exam showed tenderness and an empty rectum. Imaging confirmed sigmoid volvulus. Surgery revealed a large sigmoid tumor causing obstruction. The tumor was resected, and a colostomy was performed. Clinical discussion: Volvulus is a condition where the intestine twists, causing obstruction. It's often linked to diet, laxative use, and anatomical factors. Symptoms include abdominal pain and distension. In rare cases, it can occur with colon cancer. Conclusion: The tumor likely acted as a lead point, contributing to the development of volvulus in the long sigmoid colon. © 2025 The Authors
