Duodenal obstruction caused by ileocolic intussusception in the absence of intestinal malrotation is extremely rare. We present and discuss the imaging findings in an infant with an intussusception secondary to a duplication cyst in whom sonography also showed inversion of the orientation of the mesenteric vessels and a distended stomach. A contrast medium study revealed a proximal duodenal obstruction with a beak appearance suggestive of midgut volvulus. At surgery, an ileocolic intussusception causing duodenal obstruction without concomitant malrotation or volvulus was found. The combination of duodenal obstruction and abnormal relationship of the mesenteric vessels as a result of ileocolic intussusception has not previously been reported in the literature.

Acute Mesenteric Ischaemia (AMI) is an uncommon vascular emergency where the diagnosis is often difficult and overlooked and delay in diagnosis results in a grave outcome. Although extravascular events like intussusception, volvulus, strangulated hernia and adhesive obstruction in neglected cases can result intestinal gangrene, this contribution will be limited to acute mesenteric ischaemia as a primary event. AMI consists of four pathologic processes (arterial thrombosis, arterial embolism, Non Occlusive Mesenteric Ischaemia (NOMI) and mesenteric venous thrombosis (MVT)) with similar clinical presentation and one potentially fatal pathological endpoint- intestinal gangrene. The clinical setting and the patient's risk profile often give the clue to the etiological process while the presentation is dominated by severe unrelenting abdominal pain out of proportion to the physical findings. The key to the successful management depends on the surgeon's ability to suspect the diagnosis, pursue appropriate investigations and institute aggressive treatment. The mortality remains high due to difficulty and delay in the diagnosis.

Abdominal pain and gastrointestinal symptoms such as vomiting or diarrhea are common chief complaints in young children who present in emergency departments. It is the emergency physician's role to differentiate between a self-limited process such as viral gastroenteritis or constipation and more life-threatening surgical emergencies. Considering the difficulties inherent in the pediatric examination, it is not surprising that appendicitis, intussusception, and malrotation with volvulus continue to be among the most elusive diagnoses. This article reviews both the self-limited and more life-threatening gastrointestinal conditions that may present in the emergency department.

A German shepherd dog was presented two months after surgery for correction of acute gastric dilatation volvulus. The dog had been diagnosed with exocrine pancreatic insufficiency. Radiographs revealed marked gaseous distension of one loop of intestine with a generalised increase in intestinal gas content. A 360 degrees anticlockwise rotation of the descending and transverse colon, around the longitudinal axis of the mesocolon, was diagnosed at exploratory coeliotomy. The transverse and descending colon appeared uniformly necrotic and an end-to-end colo-colic resection and anastomosis was performed. The dog initially made satisfactory postoperative progress but was euthanased on the third postoperative day after it developed an intestinal intussusception.

Obstruction of the small intestine is a recognized complication after Roux-en-Y gastric bypass surgery for morbid obesity. Reported causes after bariatric surgery include volvulus, adhesion, internal hernia, hemorrhagic bezoar, incarcerated ventral hernia, and intussusception. Intussusception after Roux-en-Y gastric bypass for morbid obesity is rare. The etiology remains largely obscure. A delay in the diagnosis and management may result in catastrophic outcomes. Management should include the early involvement of a bariatric surgeon. We describe the clinical and radiologic presentation of a case of jejunojejunal intussusception 4 years after open Roux-en-Y gastric bypass.

Familial cases of the various types of intestinal atresia are well described, and we now report an additional family. Based on a review of the literature, a classification system for the different types of familial atresia is presented. Current teaching attributes most jejunoileal atresias to in utero vascular accidents occurring relatively late in gestation (after the 11th or 12th week). Although some cases clearly occur this way, as a result of processes such as volvulus and intussusception, knowledge of the familial form of the disease indicates that most cases of jejunoileal atresia actually result from disruption of a normal embryologic pathway, most likely the development of the superior mesenteric artery and its branches. They should be considered to be true embryologic malformations rather than acquired lesions.

A man, age 68, presented with two rare clinical entities of adult bowel obstruction. This case showed a caecocolic intussusception (due to a caecal malignant lesion) with a small bowel volvulus secondarily. These are rare but potential life-threatening surgical emergencies.

Alimentary tract duplications (ATDs) are rare congenital anomalies, with an incidence of 1 in 4500 individuals. Patients with these lesions present in a variety of ways, and although histologically benign, ATDs can lead to lethal complications including volvulus, intussusception, or bowel obstruction. Irrespective of anatomical location, the epithelial lining of ATDs contains ectopic acid-secreting mucosa in more than 50% of cases, which can lead to ulceration, bleeding, or transmural erosion and perforation. We report an unusual case of a child who presented with small bowel obstruction caused by an ileal duplication cyst that had become infected with Salmonella. Although reports of infected mesenteric cysts and duodenal duplication cysts have been published, this is the first reported case of an infected ileal duplication cyst. We also present a review of the literature regarding these interesting lesions.

Jejunal diverticuli are rare and usually asymptomatic. More commonly, they are seen as incidental findings on CT images, enteroclysis, or during surgery. Complications such as bleeding, perforation, obstruction, malabsorption, diverticulitis, blind loop syndrome, volvulus, and intussusception may warrant surgical intervention. An interesting case of an unborn enterolith (enclosed calculus) from a jejunal diverticulum presenting as a small bowel obstruction is presented. The patient is a 66-year- old woman with no prior history of abdominal surgery who presented with a high-grade bowel obstruction. CT with intravenous barium contrast confirmed the presence of a transition point from dilated to decompressed small bowel in the mid jejunum. At laparotomy, a freely mobile mass was found in this area leading to the bowel obstruction. The mass was removed by making a small enterotomy in the jejunum. While running the small bowel proximally, a small segment of jejunum, approximately 8 cm, containing several diverticuli was found. This bowel obstruction was the result of an unborn enterolith from this segment of bowel. The patient's hospitalization was benign and she was discharged home on postoperative day 4.

Midgut volvulus presenting outside the neonatal period often manifests with less than classic findings. One must be ever vigilant for any deviation from normal when imaging the gastrointestinal tract in these patients. Plain films often are noncontributory, and gastrointestinal imaging findings frequently are subtle and not exactly the same as those seen in classic cases in the neonatal period. Cases are presented illustrating the following: abnormal but less than classic small bowel location and configuration, malabsorption and fortuitous spiraling of a nasogastric tube, viral gastroenteritis and pseudo intussusception, intractable vomiting and dehydration with abnormal cecal position, and duodenal obstruction: pseudo SMA syndrome. Fortunately, one now can confirm one's suspicions with computed tomography and ultrasound in terms of determining whether the superior mesenteric artery and superior mesenteric vein positions are normal or reversed.
