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 ).
A 42-year-old woman with no relevant medical history, presented at the Emergency Department\nwith epigastric pain, of sudden beginning and progressive worsening, with a few hours of\nevolution. Mild abdominal distension and pain on palpation were noted, but there were no\nsigns of peritoneal irritation. An increase of pancreatic enzymes (amylase: 201 U/L and\nlipase: 880 U/L) was observed and recorded as abnormal finding. As there was diagnostic\nuncertainty and no obvious cause for acute pancreatitis, an abdominal-pelvic CT was\nperformed. It reported the presence of an interposition of the transverse colon between the\nleft lobe of the liver and the stomach, probably related to a foramen of Winslow hernia.\nThere was no pneumoperitoneum. Only a small quantity of free liquid was observed.\nThe patient was submitted to an urgent diagnostic laparoscopy to confirm the imaging\nfindings. The reduction of the hernia contents and the closure of the foramen were carried\nout. There was no need for bowel resection, since there was appropriate viability of the\ncolon (Figs –).\nThe postoperative care progressed favorably without complications. The diet was started on\nthe first postoperative day, being the intestinal transit restored. The patient was\ndischarged on the third day after surgery. After 15 months of follow-up, the patient was\nasymptomatic and there was no evidence of recurrence.
