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 ).
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.
