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.
A 44-year-old female patient, without prior abdominal surgery, was admitted to the emergency department with an acute epigastric abdominal pain, without nausea. She presented similar episodes of pain in the past, without having ever requested a medical opinion. Physical examination revealed an acute epigastric pain without signs of peritonitis. Laboratory analyses were within normal limits. A computed tomography showed an internal hernia of the colon in the lesser sac, going back from the liver pedicle (). There were neither occlusion nor ischemia. We performed immediately a diagnostic laparoscopy with one 11-mm umbilical port and two 5-mm ports (one in the left lumbar and one in the hypogastrium). Exploration confirmed that the ascending colon and the right colonic flexure had herniated through the foramen of Winslow (). The colon was reduced with an atraumatic Johann’s graspers and was viable, cecum, ascending colon and the right colonic flexure was mobile due to a misapposition of the right Told fascia. To prevent recurrent herniation we performed the fixation to the lateral wall of the cecum, ascending colon and right colonic flexure with several non-absorbable sutures (). We did not perform the closure of the Winslow’s hiatus. Postoperatively, the patient recovery was uneventful and was discharged home 2 days later. A computed tomography was performed 1 month later for another reason, showing a good result of the right colon fixation on the lateral wall (). Twenty months after surgery, the patient totally recovered and has not experienced any recurrence or occlusion.
