A 41-year-old woman presented with a 2-day history of severe, central, cramping abdominal pain of gradual onset, which progressively radiated to the right side of her abdomen. It was relieved by lying on her right side, assuming the foetal position or by bending forwards on the floor. Conversely straightening or stretching her abdomen exacerbated the pain. The patient had not opened her bowels (although she was still passing small amounts of flatus) in 3 days and had been vomiting for 48 h.\nHer laboratory results showed leukocytosis of 14.4 × 109, her other results were unremarkable.\nPlain abdominal radiography (Fig. ) displayed a dilated viscus in the left upper quadrant with absence of colonic shadow on the right side of the abdomen. Initially this was reported as a large distended stomach, but in retrospect was thought to be the caecum.\nAn ultrasound scan of her gall bladder was performed to rule out the possibility of acute cholecystitis; this showed a small amount of free fluid and a known ovarian dermoid cyst.\nComputed tomography was used for diagnosis. Although initially reported as caecal volvulus, in hindsight there were features indicative of the herniation. (Figs and ).\nOn the basis of the computed tomography findings, the patient was taken to theatre for her presumed caecal volvulus. At laparotomy however, the caecum was noted to be herniating through the foramen of Winslow causing closed loop obstruction. It could not be reduced by gentle traction, so the lesser sac was opened up and the caecum decompressed with a small enterotomy and suction to allow reduction. A right hemicolectomy with stapled side-to-side anastomosis was then performed to remove the compromised bowel and the foramen was left open. The patient had an uneventful postoperative recovery and was discharged 4 days later (Figs and ).
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.
