A 47-year-old woman presented to the emergency department with generalized abdominal pain for a duration of four days. The pain was intermittent and colicky in nature with a mild response to analgesia. It was associated with vomiting and abdominal distension, with absolute constipation. The patient denied experiencing a similar previous attack. Her medical and surgical histories were unremarkable, and she reported only having an irregular menstrual cycle. She also reported no history of trauma.\nUpon physical examination, the patient was found to have stable vital signs: temperature, 36.7°C; heart rate, 88 beats per minute; and oxygen saturation, 100% room air. An abdominal examination revealed mild abdominal distention with generalized tenderness but no guarding or rigidity; the abdomen was tympanic to percussion, and a digital rectal examination was unremarkable. A provisional diagnosis was made for intestinal obstruction.\nLaboratory investigations, including a complete blood count, urea and analysis, and coagulation profile, were all within normal limits. An abdominal X-ray showed a dilated large bowel with few air fluid levels, no gas in the rectum and no air under the diaphragm (Fig. ). An abdominal CT scan with oral and intravenous contrast showed that the cecum was flipped superiorly and positioned anteriorly to the transverse colon, and it herniated into the foramen of Winslow (opening between the inferior vena cava and portal vein). The cecum occupied the lesser sac, and it was distended with gas and caused a mass effect on the stomach and hepatic root, with associated intrahepatic bile duct dilatation. This was associated with proximal small bowel dilatation and collapsed large bowel loops distally (Fig. ). These findings were consistent with an obstructive internal hernia into the lesser sac through the foramen of Winslow.\nA surgical consultation was requested, and laparoscopic assisted internal hernia reduction with ileocecal resection and side-to-side anastomosis were offered. The cecum and terminal ileum, along with the appendix, had herniated through the foramen of Winslow as evidenced during laparoscopy (Video 1). Both the cecum and terminal ileum were markedly distended and probably less vascularized (Fig. ). Consequently, the cecum and terminal ileum were resected (Fig. ).\nThe patient’s postoperative was uneventful. She was started on a clear liquid diet and then advanced to solid foods by Day 2. The patient was discharged, and she did not show any signs or symptoms suggestive of complications or recurrence during the last follow-up.
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.
