A 20-year-old male of Middle Eastern descent, with a surgical history of a Ladd's procedure, walked into the emergency room complaining of severe diffuse abdominal pain and multiple episodes of emesis starting 24 prior to admission. The otherwise healthy patient had a Ladd's procedure six years prior due to intestinal malrotation. The patient denies the passing of stool or flatulence in the day prior to his admission and did not have a fever. On physical examination, the vital signs were normal, the abdomen was non-distended, peristalsis was weak on auscultation and pain was noted on palpation in the right upper quadrant. There were no signs of peritonitis.\nAt this stage, the differential diagnosis included small bowel obstruction due to adhesions, a perforated gastrointestinal ulcer and an internal hernia. A nil per os (NPO) laboratory test and an abdominal X-ray were ordered. IV fluids and analgesic were prescribed. Laboratory test showed a white blood cell count of 12 K, Lactate levels were within normal range, and no electrolyte abnormalities were found.\nAt that point, it was decided to order a CT scan and insert a nasogastric (NG) tube. The NG tube subsequently failed entry. The abdominal CT showed mesenteroaxial gastric volvulus and showed the presence of air within the Falciform Ligament (). Clinical and radiological findings led to the decision to proceed to the operating room. Consultation with a radiologist raised suspicions that possible adhesions were present in the upper abdomen. Furthermore, the patient had a midline laparotomy due to a Ladd's procedure. Consequently, the surgeon, a young specialist 2-year post-surgery residency, felt more comfortable with an exploratory laparotomy rather than a laparoscopic approach.\nThe patient was laid supine, and isoflurane was used for inhaled analgesia. During the operation, the cecum was in lower abdominal cavity and a necrotic strangulated small intestine loop was visualized within the Winslow foramen (). An excision and anastomosis procedure was conducted, and the cecum was fixed in the lower left quadrant.\nPostoperatively, the patient felt well and maintained normal vital signs. On the second post-operative day, the abdominal swelling gradually reduced, peristalsis was normal, the abdomen was non-tender and the patient returned to enteral feeding following the ERAS protocol. On post-operative day three, the patient eliminated stool and flatulence. The patient was discharged from the hospital on the fifth post-operative day in good clinical condition with nonrestrictive enteral feeding and minimal abdominal discomfort. The patient was advised to maintain good hydration, avoid weightlifting or straining, use laxatives if required and seek medical attention in case of fever or recurrence of symptoms.\nTwo weeks after the surgery, during a follow-up at the outpatient clinic, the abdominal pain was completely resolved. He consumed a normal diet, had plenty of fluids and felt well without any further complaints.
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.
