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.
A male patient, 69-years old was presented in our emergency department complaining of severe abdominal pain. The patient described the pain as paroxysmal cramps, which starts at the lower abdomen then radiate to the epigastrium and to the back. The complaint began approximately 24 h before the admission and was associated with distention and mild nausea. Vomiting, fever or altered bowel habits were not reported. The patient suffers from obesity, arterial hypertension, metabolic syndrome and uncomplicated sigmoid diverticulosis. He underwent a laparoscopic Nissen fundoplication 2 years ago. Few weeks after this operation, he suffered a migrated wrap that was surgically repaired. Clinical examination revealed abdominal tenderness without guarding or rigidity. Intestinal sounds were present but weak. Laboratory tests showed no significant abnormalities.\nIn absence of signs of peritonitis, we decided to proceed with further investigations. Abdominal sonography was hindered by distention. Contrast-enhanced computed tomography (CT) of the abdomen showed a single-intestinal loop, which appeared to be distended and trapped behind the stomach. As the possibility of internal herniation rose, we scheduled the patient for an urgent abdominal exploration.\nThe operative findings confirmed the radiological interpretation. The operator could retract the twisted ascending colon and caecum out of the lesser sac through the foramen of Winslow, only after decompression of the strangulated bowel, via suction of gas and fluid content through a small incision. The initially congested herniated colon regains normal appearance soon. In the absence of permanent ischemic changes, the operator opted for minimal intervention. Without colectomy, the abdomen was temporary closed, with a second-look planned after 24 h, which revealed viable intestine with no signs of intestinal obstruction. The patient stayed in the intensive care unit for 2 days and was discharged at the seventh postoperative day after he showed good recovery and uneventful hospital stay.
