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.
A 44-year-old female patient, without prior abdominal surgery, was admitted to the emergency department with an acute epigastric abdominal pain, without nausea. She presented similar episodes of pain in the past, without having ever requested a medical opinion. Physical examination revealed an acute epigastric pain without signs of peritonitis. Laboratory analyses were within normal limits. A computed tomography showed an internal hernia of the colon in the lesser sac, going back from the liver pedicle (). There were neither occlusion nor ischemia. We performed immediately a diagnostic laparoscopy with one 11-mm umbilical port and two 5-mm ports (one in the left lumbar and one in the hypogastrium). Exploration confirmed that the ascending colon and the right colonic flexure had herniated through the foramen of Winslow (). The colon was reduced with an atraumatic Johann’s graspers and was viable, cecum, ascending colon and the right colonic flexure was mobile due to a misapposition of the right Told fascia. To prevent recurrent herniation we performed the fixation to the lateral wall of the cecum, ascending colon and right colonic flexure with several non-absorbable sutures (). We did not perform the closure of the Winslow’s hiatus. Postoperatively, the patient recovery was uneventful and was discharged home 2 days later. A computed tomography was performed 1 month later for another reason, showing a good result of the right colon fixation on the lateral wall (). Twenty months after surgery, the patient totally recovered and has not experienced any recurrence or occlusion.
