A 58-year-old male patient, who had a medical history of diabetes mellitus, hypertension, and coronary artery disease, underwent coronary angiography and stenting 18 years earlier. He had not had any prior abdominal surgeries or trauma. The patient came to the emergency department with a 1-day history of abdominal pain, accompanied by vomiting and constipation, though he was able to pass a minimal amount of gas. There was no fever or other gastrointestinal symptoms. The pain was mainly located in the infraumbilical to suprapubic area, with a slight shift to the left iliac fossa, and was colicky in nature. A few hours after his arrival in the emergency room, he developed a rigid abdomen and was unable to move or cough. No additional system abnormalities were found. His vital signs were normal. On examination, the patient's abdomen was distended, without scars, and displayed tenderness in the lower area, specifically towards the left iliac fossa. There was no rebound tenderness, but guarding was present in the abdominal muscles in this region. Percussion of the abdomen yielded a slight tympanic sound, and there was a decrease in bowel sounds. A digital rectal examination found normal-colored stool in a fully loaded rectum. Laboratory findings were mostly normal, except for an elevated white blood count of 13.2 × 103 µl and slightly increased amylase and lipase levels at 179 and 149 µl, respectively. An abdominal plain x-ray showed dilated jejunal loops in the small intestine with a bowel diameter of 4.5 cm, mainly in the mid-abdomen, without air-fluid levels or free air (). While in the emergency department, the patient underwent an ultrasound, revealing mildly dilated, fluid-filled bowel loops and some free fluid in the left lower quadrant (). A CT scan of the abdomen with oral and intravenous contrast was performed to identify any surgical pathology. It revealed a transition point in the left mid-abdomen associated with dilated, fluid-filled proximal jejunal loops and collapsed distal small bowel loops. Also evident were long segment wall thickening of the distal jejunal/proximal ileal loop, mesenteric fat stranding, and a small amount of perihepatic fluid (). During the patient's examination, his vital signs started to show signs of decline, with a blood pressure reading of 80/60 mmHg, an elevated heart rate at 110 beats per minute, and increased lactate levels at 3 mmol/L. Consequently, he was transferred to the surgical critical care unit for urgent resuscitation. An abdominal examination revealed peritonitis and noticeable abdominal distension. Despite the offer of a nasogastric tube for abdominal decompression, the patient deteriorated. A comprehensive cardiology evaluation was performed, and the patient was prepared for an urgent exploratory laparotomy. In the operation room, a midline exploratory laparotomy revealed a large volume of hemorrhagic fluid filling the entire abdominal cavity. The surgical findings also showed about 1 L of reactive hemorrhagic fluid and a notable adhesion between two Appendices epiploicae (AE) of the sigmoid colon. This adhesion had formed a ring that trapped and caused the small intestine to become gangrenous. Specifically, a 120 cm segment of the small bowel, located 50 cm from the ileocecal valve, was affected. The surgical team divided the AE ring to release the entrapped bowel, and the gangrenous portion of the bowel was removed and repaired with primary anastomosis (see ). The patient was then transferred to the Intensive Care Unit (ICU) for management and correction of abnormal parameters. Following a satisfactory post-operative recovery, he was discharged in excellent health.
