An 81-year-old female with a medical history of CAD with stents, hyperlipidemia, hypothyroidism, GERD, recent UTI, pancreatic cyst, constipation, anemia and leukopenia presented to the ED with a 1 day history of mild, diffuse and cramping abdominal pain. The patient was unable to give an accurate history, but the son at bedside supplemented this reporting that for several years the patient had been experiencing ill-defined abdominal discomfort. Physical exam showed a soft abdomen with mild tenderness and no evidence of peritonitis. A CT scan of the abdomen and pelvis with IV and PO contrast (Fig. ) showed edematous changes to the mesentery of the small and large bowel with swirling of vessels indicative of internal hernia. The stomach was also noted to be distended with both air and fluid as a consequence of posterior compression by the hernia contents (Fig. ). A surgical consult was obtained, a nasogastric tube and Foley catheter were placed, antibiotics were started, and the patient was taken for an exploratory laparotomy. Upon entering the abdomen through a vertical midline incision, 1.5 l of ascites was drained revealing a diffusely edematous mesentery. A large portion of the small bowel was seen to be herniated through the Foramen of Winslow (Fig. ). A Kocher maneuver and division of the gastrocolic ligament were then performed to allow release of the herniated small bowel. It was at this time that, in addition to small bowel, a large portion of the ascending and transverse colon was noted to be herniated through the foramen of Winslow. The small bowel was also seen to be torsed about its own mesentery. Normal anatomy was restored and the bowel noted to be healthy and viable with peristalsis (Fig. ). Due to the large size of the foramen after reduction and enlargement, it was deemed best to leave it open to prevent any further incarceration or strangulation. The abdomen was closed and the patient tolerated the procedure well. At a follow-up visit 2 months later, the patient had well-healed incisions, was doing well, tolerating a diet, and gaining weight appropriately.
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.
