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.
The patient is a 70-year-old woman who presented to the emergency department with acute-onset abdominal pain throughout her epigastrium for approximately 2 hours. The pain was constant and severe, extending across the bilateral upper quadrants. She had experienced pain like this once before within the past year which spontaneously resolved within 4 hours. The patient’s last oral intake was an hour before onset of the pain, and she denied any fevers, chills, nausea or vomiting. She was an otherwise healthy woman who took no medications and had no abdominal surgical history. On admission, vital signs were normal, with a heart rate in the 70’s. Although initially reported as tender by emergency department staff, after pain medication and intravenous fluids, examination by the surgical team revealed resolution of pain and a soft, non-tender abdomen. Lactic acid on presentation was 5.0 mmol/l, and her white blood cell count was 9600 µl−1, with the remainder of her laboratory values within normal limits. She underwent a computed tomography scan which demonstrated herniation of her cecum through the FoW, causing compression of the inferior vena cava (IVC) and portal vein (Figures –).\nThe patient was taken to the operating room for a laparotomy. On exploration, the cecum was found to be free-floating with significant mobility of the right colon mesentery. It appeared to have spontaneously reduced. A right hemicolectomy was performed, resecting all the redundant right-sided colon and creating a primary side-to-side functional end-to-end anastomosis.\nPost-operatively, the patient’s presenting pain had resolved, she tolerated rapid advancement of diet, and was discharged once bowel function was regained. She was seen in the outpatient clinic at 2 weeks post-operatively and was doing well without recurrence of symptoms.
