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 52-year-old woman with unremarkable medical and surgical history presented to the emergency department with intermittent abdominal pain. Physical examinations revealed a soft abdomen with epigastric tenderness without signs of peritonitis. A gently uplifting mass from above the pubis to below the umbilicus was palpated. The patient’s white blood cell count was slightly increased to 12,220 cells/μL (normal value: 4000–8000 cells/μL), and other serum tests (e.g., C-reactive protein and liver enzymes) were within respective reference ranges. Abdominal contrast-enhanced CT showed the presence of large uterine fibroids in the pelvis and herniation of dilated small bowel loops between the portal vein and the inferior vena cava (Fig. ).\nNo signs of bowel ischemia or peritonitis were observed. Because abdominal pain was refractory to previously administered medications, we performed elective laparoscopic surgery after bowel decompression using a long intestinal tube on the 19th day of hospitalization.\nLaparoscopic surgery was performed using a 12-mm umbilical port and four 5-mm working ports in the bilateral epigastric and hypogastric regions (Figs. .and ). We observed that the small bowel herniated through the foramen of Winslow. Hernia reduction could not be performed simply by pulling out the herniated bowel because of the adhesion between the herniated bowel and intra-omental tissue. Hence, we incised the lesser omentum to open the lesser sac and facilitate adhesiolysis.\nBecause the herniated bowel was observed to be viable, bowel resection was not performed. No intestinal malrotation or long bowel mesentery was observed, and closure of the foramen of Winslow was not performed. Nevertheless, there were no postoperative complications and the patient was discharged on postoperative day 6. No recurrences have occurred after 12 months of follow-up.
