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.
A male patient, 69-years old was presented in our emergency department complaining of severe abdominal pain. The patient described the pain as paroxysmal cramps, which starts at the lower abdomen then radiate to the epigastrium and to the back. The complaint began approximately 24 h before the admission and was associated with distention and mild nausea. Vomiting, fever or altered bowel habits were not reported. The patient suffers from obesity, arterial hypertension, metabolic syndrome and uncomplicated sigmoid diverticulosis. He underwent a laparoscopic Nissen fundoplication 2 years ago. Few weeks after this operation, he suffered a migrated wrap that was surgically repaired. Clinical examination revealed abdominal tenderness without guarding or rigidity. Intestinal sounds were present but weak. Laboratory tests showed no significant abnormalities.\nIn absence of signs of peritonitis, we decided to proceed with further investigations. Abdominal sonography was hindered by distention. Contrast-enhanced computed tomography (CT) of the abdomen showed a single-intestinal loop, which appeared to be distended and trapped behind the stomach. As the possibility of internal herniation rose, we scheduled the patient for an urgent abdominal exploration.\nThe operative findings confirmed the radiological interpretation. The operator could retract the twisted ascending colon and caecum out of the lesser sac through the foramen of Winslow, only after decompression of the strangulated bowel, via suction of gas and fluid content through a small incision. The initially congested herniated colon regains normal appearance soon. In the absence of permanent ischemic changes, the operator opted for minimal intervention. Without colectomy, the abdomen was temporary closed, with a second-look planned after 24 h, which revealed viable intestine with no signs of intestinal obstruction. The patient stayed in the intensive care unit for 2 days and was discharged at the seventh postoperative day after he showed good recovery and uneventful hospital stay.
