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 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.
