Large bowel obstruction as a consequence of transverse colon volvulus: A case report

INTRODUCTION: Transverse colon volvulus incidence is comparatively rare when compared to cecal and sigmoid volvulus. Its diagnosis is still challenging for the surgeon. Delay in the diagnosis of this condition carries high morbidity and mortality rates. AIM: To report a rare case of transverse colon volvulus in a young adult male that presented as large bowel obstruction and was operated upon in the General Surgery department in the Jordanian Royal Medical Services (JRMS), Amman, Jordan. PRESENTATION OF CASE: An 18-year-old male presented with severe generalized abdominal pain of 12-h-duration, associated with significant abdominal distention and constipation of one-day duration. His abdominal examination revealed a massively distended, tender abdomen; however, there were no signs of peritonitis. Abdominal radiographs showed a massively dilated large bowel. He underwent exploratory laparotomy that revealed the diagnosis of transverse colon volvulus. His condition was managed operatively with transverse colectomy with a primary anastomosis. The patient had a satisfactory postoperative recovery. DISCUSSION: Only 3–5% of all cases of intestinal obstruction are caused by colonic volvulus. Transverse colon is involved in 2–4% of them. The diagnosis of transverse colon volvulus can be delayed and difficult because it does not have the same classically recognizable radiographic features as cecal and sigmoid volvulus. CONCLUSION: Transverse colon volvulus is a rare entity. A swift suspicion of diagnosis is key to preventing severe outcomes. It can result in bowel perforation and fecal peritonitis. The definitive diagnosis is frequently made intraoperatively. Early surgical intervention is essential for better outcome and avoiding complications.
