A 67-year-old male with a past medical history of prostate cancer, hypertension and prior open right inguinal hernia repair presented to the emergency department (ED) with sudden onset nausea, vomiting and abdominal pain for 2 h. The abdomen was non-distended and slightly tender in the epigastrium. A clinical diagnosis of pancreatitis was made based on physical examination, history and a mildly elevated lipase and the patient was discharged home with antiemetic medications by the ED providers. The patient presented back to the ED 2 days later with worsening abdominal pain, nausea, vomiting and obstipation. At this time his abdomen was distended and tender to palpation in the epigastrium without peritoneal irritation. Due to his obstructive clinical picture, a CT scan of the abdomen and pelvis with IV contrast () was obtained in the ED. The scan was read as a possible volvulus versus an internal hernia causing small bowel obstruction. A nasogastric tube was placed after he was admitted to the surgical unit with partial resolution of his abdominal tenderness and distention. A barium enema () was performed to rule out an obstructing distal mass, which showed a transition point at the hepatic flexure.\nDue to the clinical picture of a complete bowel obstruction and subsequent imaging findings, an urgent abdominal exploration was performed. A standard supraumbilical midline laparotomy was made and the peritoneal cavity was entered. Distended loops of bowel were encountered, and the right colon was mobilized from some loose attachments to the abdominal wall. The right colon was followed to identify the cecum and terminal ileum. The cecum was identified to be in the lesser sac, herniated through the foramen of Winslow. The cecum was reduced and was determined to be ischemic and nonviable, so a right hemicolectomy was performed with an isoperistaltic ileocolic anastomosis with the transverse colon. The duodenum was Kocherized to expose the retroperitoneum. The foramen of Winslow was closed by approximating the hepatoduodenal ligament to peritoneum overlying the right kidney with a simple interrupted 3–0 polyglyconate suture, adequately obliterating the foramen. The transverse colon was pexy to the anterior abdominal wall using 3–0 polyglyconate suture.\nHis postoperative course was uncomplicated. His intestinal transit was restored on postoperative Day 3. His diet was advanced as tolerated. He was discharged on Day 5 after surgery with good diet tolerance and having adequate bowel function. Pathology was benign.
A 47-year-old woman presented to the emergency department with generalized abdominal pain for a duration of four days. The pain was intermittent and colicky in nature with a mild response to analgesia. It was associated with vomiting and abdominal distension, with absolute constipation. The patient denied experiencing a similar previous attack. Her medical and surgical histories were unremarkable, and she reported only having an irregular menstrual cycle. She also reported no history of trauma.\nUpon physical examination, the patient was found to have stable vital signs: temperature, 36.7°C; heart rate, 88 beats per minute; and oxygen saturation, 100% room air. An abdominal examination revealed mild abdominal distention with generalized tenderness but no guarding or rigidity; the abdomen was tympanic to percussion, and a digital rectal examination was unremarkable. A provisional diagnosis was made for intestinal obstruction.\nLaboratory investigations, including a complete blood count, urea and analysis, and coagulation profile, were all within normal limits. An abdominal X-ray showed a dilated large bowel with few air fluid levels, no gas in the rectum and no air under the diaphragm (Fig. ). An abdominal CT scan with oral and intravenous contrast showed that the cecum was flipped superiorly and positioned anteriorly to the transverse colon, and it herniated into the foramen of Winslow (opening between the inferior vena cava and portal vein). The cecum occupied the lesser sac, and it was distended with gas and caused a mass effect on the stomach and hepatic root, with associated intrahepatic bile duct dilatation. This was associated with proximal small bowel dilatation and collapsed large bowel loops distally (Fig. ). These findings were consistent with an obstructive internal hernia into the lesser sac through the foramen of Winslow.\nA surgical consultation was requested, and laparoscopic assisted internal hernia reduction with ileocecal resection and side-to-side anastomosis were offered. The cecum and terminal ileum, along with the appendix, had herniated through the foramen of Winslow as evidenced during laparoscopy (Video 1). Both the cecum and terminal ileum were markedly distended and probably less vascularized (Fig. ). Consequently, the cecum and terminal ileum were resected (Fig. ).\nThe patient’s postoperative was uneventful. She was started on a clear liquid diet and then advanced to solid foods by Day 2. The patient was discharged, and she did not show any signs or symptoms suggestive of complications or recurrence during the last follow-up.
