Background: Intussusception is the most common cause of bowel obstruction in children aged 3 months to 6 years of age. We sought to describe patterns of incident childhood intussusception.

Methods: A retrospective longitudinal cohort study utilizing population-based health administrative data and a validated case definition was used to identify patients <18 years of age treated for intussusception between January 1, 1997 and December 31, 2016 in Ontario, Canada. Read More

Introduction: Jejunogastric intussusception following gastrectomy or gastric bypass surgery is a rare complication that, if not identified early, can have catastrophic outcomes.

Presentation Of Case: In this case, a 59-year-old male with a previous Billroth II gastrojejunostomy presented with intussusception of the efferent loop of jejunum through his previous repair.

Discussion: As there has only been approximately 300 reported cases of this complication, it often does not rank high as a differential diagnosis. Read More

Background: Intussusception occurs when a segment of the bowel (the intussusceptum) telescopes into an adjacent segment (the intussuscipiens). Adult intussusception occurs rarely and often requires surgical resection for its treatment. We describe the case of an adult patient with extremely rare cecorectal intussusception treated using a novel combined transabdominal and trans-anal approach, which has not yet been reported in the literature.

Background: Pyogenic granuloma is a benign vascular tumor, usually occurring on the skin or in the oral cavity. Small intestinal pyogenic granuloma is extremely rare, but intestinal intussusception due to the tumor is even rarer. Only 3 cases have been reported in the English literature at this writing.

Henoch-Schönlein purpura (HSP) is a childhood vasculitis disorder that involves the skin, joints, gastrointestinal (GI) tract, and kidneys. It is related to immunoglobulin A (IgA) antibody deposition in small blood vessels. HSP is a self-limiting disorder, but its morbidity is primarily associated with renal involvement. Read More

Intussusception is a common paediatric emergency which can be diagnosed with relative certainty by ultrasonography in trained hands. Both the ileocolic and small-bowel intussusception have overlapping clinical features and imaging findings on ultrasound. The aim is to differentiate between both subtypes based on selective differentiating features which should always be looked for while performing an ultrasound examination in suspected cases.

Summary: Intussusception is a well-known complication of Henoch-Schönlein purpura (HSP).1 Diagnosis of intussusception is based on well-defined clinical and radiological features, but certain conditions can mimic intussusception, both clinically and radiologically, so closely as to result in unnecessary invasive procedures. Authors here present a case of HSP complicated by severe acute jejunitis, masquerading as jejuno-jejunal intussusception on ultrasound. Read More

Inverted Meckel's diverticulum is an entity often discovered incidentally or through a clinical evaluation for gastrointestinal bleeding. While rare, inverted Meckel's diverticulum should be considered in the evaluation of a patient presenting with gastrointestinal bleeding, intestinal obstruction, or intussusception. In this case, a 67-year-old female with a remote history of surgically treated breast cancer presents to an urgent care facility with weakness and fatigue. Read More

Introduction And Importance: Intestinal intussusception is rare in adults and it is associated with lead points affecting the colon in around 17% of patients. Lipomas are very rare benign tumors which may act as lead points for intestinal intussusception. Indeed, the incidence of intestinal intussusception is much rare when caused by lipomas. Read More

Intussusception is the invagination and telescopic migration of a proximal segment of the gastrointestinal tract distally and is classically described in the paediatric age group, accounting for 95% of reported cases. Intussusception in adults is highly uncommon; its aetiology involves a wide spectrum of pathologies, namely, concerning malignancy and differing management pathways. In the management of adult intussusception, consideration must be given to the potential malignant nature of the lesion, as reducing a malignant segment could render dissemination. Read More

Reports of intussusception in sea turtles are generally linked to marine debris ingestion; therefore, only a few cases of the disease are associated with parasitic infestations. The objective of this study was to describe the necropsy findings of the first reported case of colocolic intussusception in a green sea turtle Chelonia mydas, associated with the helminth Octangium sp. A juvenile female green sea turtle, which was registered and rescued by the team from the Cetaceans Project of Costa Branca, State University of Rio Grande do Norte, was examined. Read More

Heterotopic pancreas (HP) is a developmental anomaly defined as aberrantly located pancreatic tissue with no anatomical, vascular, or neural connection to the pancreas. Bowel intussusception and gastrointestinal bleeding caused by isolated HP is extremely rare. This study explores the clinical, radiographical, pathologic, and treatment features of four patients with intussusception caused by incidental HP, with the aim of providing important insight into the diagnosis and management of these patients.

A 38-year-old man visited our hospital with a complaint of diarrhea and abdominal pain. Contrast-enhanced computed tomography showed that the ileocecal site was intussuscepted to the transverse colon without ischemia. After we reduced intussusception with an enema using a water-soluble contrast agent, his abdominal pain disappeared. Read More

Feeding jejunostomy (FJ) is a common surgical procedure for patients presenting with absolute dysphagia. Jejunostomy tube-induced intussusception is an extremely rare complication associated with it and its recognition and proper management are necessary to prevent subsequent bowel ischemia of the intussusception. We present a rare case with simultaneous intussusception at two sites in a patient who underwent FJ with Foley's catheter one month back and subsequently managed by surgical reduction and repositioning of the FJ tube.

Introduction And Hypothesis: Symptoms of obstructed defecation (OD) and anatomical abnormalities of the posterior compartment are prevalent in urogynecological patients. The aim of this study was to determine whether perineal hypermobility is an independent predictor of OD, as is the case for rectocele, enterocele and rectal intussusception.

Intussusception is a rare yet potentially life-threatening complication following Roux-en-Y gastric bypass (RYGB). Multiple case reports have described this complication, and recently, several retrospective studies have been published describing the surgical treatment of intussusception.
