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 63-year-old woman with a history of gastroesophageal reflux disease (GERD) associated with a small hiatal hernia presented to the emergency department with severe abdominal pain, nausea, vomiting, and obstructive symptoms that had started 12 hours earlier. The pain was epigastric in nature. She reported no passing of flatus or bowel movement for 24 hours prior to presentation. She also reported a history of intermittent abdominal pain and obstipation that would self-resolve without treatment over the last several years. She had no prior surgical history. Her body mass index was 31. She denied any fever, chills, chest pain, or shortness of breath. Her vitals on presentation included a blood pressure of 110/70 mm Hg, heart rate of 105 beats per minute, and respiratory rate of 22 breathes per minutes. On physical examination, the abdomen was distended with focal tenderness in the epigastric and peri-umbilical regions. No peritoneal signs were noted.\nLaboratory analysis revealed a leukocytosis to 12.9 K/uL (reference range [RR]; 4.0-10.0K/uL) with an elevation in creatinine to 0.8 mg/dL from 0.4 mg/dL (RR; 0.3 -0.6mg/dL). Her blood urea nitrogen level was elevated to 20 mg/dL from 8 mg/dL (RR; 4 – 8 mg/dL). Her lipase, amylase, and liver function tests were within normal limits. Her lactate level was mildly elevated to 3.0 mg/dL (RR; 0.5-1mmol/L).\nA computed tomography (CT) scan of her abdomen and pelvis revealed a right internal hernia containing cecal bascule herniation through the foramen of Winslow into the lesser sac, concerning for a closed-loop obstruction (). There was fecalization with upstream bowel dilation. There was no evidence of pneumoperitoneum, pneumatosis, or bowel wall compromise. A normal appendix was also noted in the right upper quadrant near the gallbladder.\nThe patient’s symptoms including pain, nausea, vomiting, no flatus or bowel movements, along with her leukocytosis and imaging findings were concerning for an internal hernia with a cecal bascule traversing the foramen of Winslow causing a closed-loop obstruction. The patient was taken to the operating room.\nShe underwent an exploratory laparotomy. After fixed retractors were placed, the appendix was noted to be in the right upper quadrant near the gallbladder and liver edge (). The terminal ileum and transverse colon were noted to be tracking behind the portal triad. Upon closer examination, these structures were noted to be involved in an internal hernia with a cecal bascule herniating through the foramen of Winslow. Adhesions were lysed and the hernia sac was partially excised facilitating reduction of the cecal bascule (). The colon was noted to be viable. After reduction, the hernia sac was fully excised. The right colon mesentery was noted to be highly redundant ().\nGiven the viability of the cecum and right colon, the decision was made to perform a cecopexy rather than right hemicolectomy to minimize the risk of a recurrent internal hernia. An appendectomy was also performed. Omentum was placed near the foramen of Winslow to also help prevent future risk of a recurrent internal hernia. No attempt was made at suture closure of the foramen of Winslow space. The abdomen was closed in the standard fashion.\nThe patient’s postoperative course was uncomplicated. Her pain was well-controlled with oral pain medication. Her diet was advanced in a stepwise fashion. She was able to ambulate independently and void spontaneously upon discharge. The patient was discharged 4 days following her operation. She has also been doing well more than 6 months out from surgery.
