A 75-year old male presented to the emergency room with worsening abdominal pain and distension. Plain radiographs were suggestive of a large bowel obstruction due to volvulus. An attempt to detorse the volvulus and decompress the colon endoscopically failed, after which the patient was taken for an exploratory laparotomy. A transverse colon volvulus was found, and an extended right hemicolectomy and ileostomy was performed. We discuss the diagnosis and management of transverse colon volvulus and review the pertinent literature.
Case presentationA 75-year old Caucasian male presented to the emergency department with severe abdominal distension and mild dyspnea. A retired auto factory worker, he was 5 feet 9 inches tall and 250 pounds. His medical history was significant for diabetes mellitus, coronary artery disease, and a myocardial infarction. He had undergone bilateral inguinal hernia repairs. Medications included metoprolol, aspirin, enalapril, and metformin. The patient was reformed smoker, and drank alcohol occasionally. His family history was significant for diabetes. The patient also admitted with a history of chronic constipation for which he often self-medicated with magnesium citrate. Prior to presentation his efforts had been unsuccessful, and he had not had a bowel movement for ten days.Physical examination revealed a thin elderly gentleman with a massively distended abdomen; it was tympanic to percussion with minimal bowel sounds and visibly dilated loops of bowel. The abdomen was non-tender and there were no signs of peritonitis. Digital rectal examination revealed an empty rectal vault and no intraluminal masses.Laboratory studies demonstrated leukocytosis, hypokalemia, and prerenal azotemia. Abdominal radiographs were obtained and showed massively distended large bowel, and was suggestive of obstruction due to volvulus ( Figure 1). Both hemidiaphragms were elevated because of the dilated large bowel, which likely explained the patient's dyspnea (Figure 2).Due to the massive distension, we decided against performing a barium enema. Instead, we elected to attempt endoscopic decompression and detorsion. This was preformed in the operating room to allow for the possibility of failure with conversion to laparotomy. We were unable to advance the endoscope beyond the splenic flexure. The
