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.
The patient is a 70-year-old woman who presented to the emergency department with acute-onset abdominal pain throughout her epigastrium for approximately 2 hours. The pain was constant and severe, extending across the bilateral upper quadrants. She had experienced pain like this once before within the past year which spontaneously resolved within 4 hours. The patient’s last oral intake was an hour before onset of the pain, and she denied any fevers, chills, nausea or vomiting. She was an otherwise healthy woman who took no medications and had no abdominal surgical history. On admission, vital signs were normal, with a heart rate in the 70’s. Although initially reported as tender by emergency department staff, after pain medication and intravenous fluids, examination by the surgical team revealed resolution of pain and a soft, non-tender abdomen. Lactic acid on presentation was 5.0 mmol/l, and her white blood cell count was 9600 µl−1, with the remainder of her laboratory values within normal limits. She underwent a computed tomography scan which demonstrated herniation of her cecum through the FoW, causing compression of the inferior vena cava (IVC) and portal vein (Figures –).\nThe patient was taken to the operating room for a laparotomy. On exploration, the cecum was found to be free-floating with significant mobility of the right colon mesentery. It appeared to have spontaneously reduced. A right hemicolectomy was performed, resecting all the redundant right-sided colon and creating a primary side-to-side functional end-to-end anastomosis.\nPost-operatively, the patient’s presenting pain had resolved, she tolerated rapid advancement of diet, and was discharged once bowel function was regained. She was seen in the outpatient clinic at 2 weeks post-operatively and was doing well without recurrence of symptoms.
