Inflammatory fibroid polyps (Vanek's tumor) are rare benign localized lesions originating in the submucosa of the gastrointestinal tract. Intussusceptions due to inflammatory fibroid polyps are uncommon; moreover, ileo-ileal intussusception with small bowel necrosis and perforation has rarely been reported. We report a 56-year-old woman who was admitted two days after complaints of nausea and vomiting. Abdominal examination revealed distension, signs of gastrointestinal perforation and clanging intestinal sounds. The patient underwent a emergency laparotomy which found a 17-cm invaginated mid-ileal segment with necrosis, perforation and fecal peritonitis. The ileal segment was resected and single-layer end-to-end anastomosis was performed. Histopathological analysis showed an ulcerative lesion with variable cellularity, formed by spindle cells with small number of mitosis and an abundant inflammatory infiltrate comprising mainly eosinophils. Immunohistochemistry confirmed the diagnosis of ileal Vanek's tumor. Although inflammatory fibroid polyps are seen very rarely in adults, they are among the probable diagnoses that should be considered in obstructive tumors of the small bowel causing intussusception with intestinal necrosis and perforation.

Intussusception involving heterotopic pancreatic tissue is a rare condition where a portion of the bowel telescopes into an adjacent segment with intraluminal pancreatic tissue as the lead point. Cases of heterotopic pancreas are most often described in the upper intestinal tract, particularly the stomach.
We present the case of a five-month-old boy of Caucasian ethnicity suffering acute abdominal pain and vomiting with an abdominal mass in the upper right quadrant. Work-up including ultrasound scan confirmed the intussusception. Repeated attempts at radiological reduction and two laparoscopic procedures were performed within 24 hours, which eventually led to the diagnosis of a triple intussusception.
To our knowledge, such a case of triple intussusception involving isolated heterotopic pancreatic tissue is previously unreported.
Intussusception is one of the less common causes of intestinal obstruction among adults. It is usually covert (concealed) in its clinical presentation. The ileo-colic type with accompanying anal protrusion is extremely rare. The case at hand is that of both an ileo-colic intussusception with anal protrusion, in the presence of a persistence of both the ascending and descending mesocolons; a case possibly yet to be documented in literature.
A 32 year-old African-Ugandan woman presented with complaints of a mass protruding per anus for 2 weeks. It was reducible and associated with colicky abdominal pain, loose stools, and bloody-mucoid discharge per anus. She had previously had a one and a half month’s history of abdominal pain; periodically continuous, while other times colicky in character. Examination and investigations revealed an intussusception with a partial intestinal obstruction. At laparotomy she was found to have an ileo-colic intussusception with a freely mobile colon throughout its length. There were persistent ascending and descending mesocolons, and absent hepatocolic and splenocolic ligaments. The intussusceptum was ‘milked’ but not completely reducible. A right hemicolectomy was done, with ileo-transverse colonic anastomosis. Histopathological examination revealed no preexisting pathologic lesion as a lead point.
The persistence of the ascending and descending mesocolons (azygosis) best explains the anal protrusion of an ileo-colic intussusception with partial obstruction. In this case zygosis (normal retroperitoneal ascending and descending colonic positioning) failed embryologically. This experience is particularly beneficial to general surgeons, radiologists, gastroenterologists, colorectal surgeons and pathologists.

Intussusception is a rare condition in the adult population. However, in contrast to its presentation in children, an identifiable etiology is found in the majority of cases. Clinical manifestations of adult intussusception are non-specific and patients may present with acute, intermittent or chronic symptoms, predominantly those of intestinal obstruction. A 27-year-old male patient with recurrent abdominal pain secondary to intussusception is herein reported. The clinical presentation and ultrasonographic findings led to the diagnosis. At laparotomy, an ileal hamartoma was found as the lead point of the intussusception. Surgical management and histopathologic studies are described. A recurrent intestinal obstruction and classic ultrasound findings may lead to the diagnosis of intussusception but surgical exploration remains essential. The principle of resection without reduction is well established.

Intussusceptions in adults is rare. Gastrointestinal lipomas are rare benign tumors and intussusceptions due to a gastrointestinal lipoma constitutes an infrequent clinical entity. Lipoma may develop as a benign tumor in all organs and rarely in large or small intestine. The present report describes a case of jejunojejunal intussusceptions in an adult with a history of colicky upper abdominal pain. Ileo-ileal invagination was diagnosed by computed tomography scan. Exploratory laparotomy revealed jejunojejunal intussusceptions secondary to a lipoma which was successfully treated with segmental intestinal resection. A review of the literature is also performed regarding this rare association revealing the diagnostic and therapeutic debates that exist.
L’invagination chez les adultes est rare. Les lipomes gastro-intestinaux sont de rares tumeurs bénignes et l’invagination intestinale due à un lipome gastro-intestinal constitue une entité clinique trés rare. Le lipome peut se développer comme une tumeur bénigne dans tous les organes et rarement dans l’intestin grêle ou le colon. Le présent rapport décrit un cas d’invagination jéjunojéjunale chez un adulte avec une histoire de douleurs abdominales. Iléo-iléale invagination a été diagnostiquée par tomodensitométrie. Une laparotomie exploratrice a révélé l’existence d’une invagination jéjunojéjunale secondaire à un lipome qui a été traitée avec succès par une résection intestinale segmentaire. Une revue de la littérature est également effectuée au sujet de cette association rare révélant les débats diagnostiques et thérapeutiques qui existent.

Lipoma and angiolipoma are common benign neoplasms that occur in the subcutaneous tissue and rarely in the gastrointestinal tract. These tumors are usually asymptomatic but may present with abdominal pain, bleeding and obstruction. We present a 53-years-old woman with abdominal discomfort for several weeks accompanied with bloody diarrhea and recurrent vomiting. Ileo-ileal invagination was diagnosed by computed tomography scan. Laparotomy revealed five intraluminal masses that caused intussusception. Histopathological study showed that one was angiolipoma and other lesions were lipoma. We have described some aspects of diagnosis and treatment of this rare cause of intestinal intussusception.
Myxomas of the small intestine are extremely rare types of primary bowel neoplasms. Their presence can trigger intestinal intussusception in the adults. We present the eighth case of intestinal myxoma reported in the English literature.
PRESENTATION OF CASE
Our patient is a 44-year-old Caucasian female who presented with clinical and imaging findings of intestinal intussusception. Laparotomy revealed ileo-ileal intussusception caused by an intramural mass of the middle-ileum which was resected. Histological and immunohistochemical studies pointed to the diagnosis of benign intestinal myxoma, while imaging studies of the heart excluded a synchronous cardiac myxoma. Twenty months after surgery she remains disease-free.
The myxoma is a benign, true neoplasm which resembles primitive mesenchyme. It occurs predominantly in the heart and is also found in several soft tissues and bones. Myxomas seem to grow at different rates of speed, they infiltrate adjacent structures and they do not metastasize, apart from cardiac variants. Intestinal myxomas share some clinical characteristics which are emphasized.
Myxomas of the small intestine should be included in the differential diagnosis of ileal tumors in middle-aged women manifesting as intestinal intussusception. Treatment should include wide resection of the affected intestinal segment with primary anastomosis. A close follow-up control of the patients along with cardiac imaging evaluation is recommended postoperatively, in order to detect and treat any possible recurrence of the tumor or a synchronous cardiac myxoma.

Peutz-Jeghers is a rare autosomal dominant disorder characterized by hamartomatous polyps and discoloration of mucosal membranes. The polyps can occur anywhere in the gastrointestinal tract and can grow large enough to cause bowel obstructions.
A 16-year-old male presented to the emergency department with signs and symptoms of an acute bowel obstruction. He had 2 days of abdominal pain, obstipation, and vomiting. He had a previous history of a colonoscopy with polypectomy at age 4, and hyperpigmentation of his mucous membranes.
Computed tomographic (CT) scan revealed an intussusception of the small intestine. An exploratory laparoscopy found an intussusception of the mid jejunum. A laparoscopic-assisted small bowel resection was performed. Pathology showed a 5-cm polyp that acted as a lead point for the intussusception. Colonoscopy and upper endoscopy revealed 5 more polyps in the stomach and colon that were removed.
Small bowel obstructions can be managed successfully with minimally invasive approaches. The treatment of obstruction in these patients is to remove the offending hamartomatous polyp(s). The rest of the intestine needs to be examined and those polyps found should be removed. This can be done intraoperatively with laparoscopic-assisted enteroscopy and colonoscopy.

Intestinal duplication is an uncommon congenital condition in young adults. A 25-year-old man complained of chronic, intermittent abdominal pain for 3 years following previous appendectomy for the treatment of suspected appendicitis. Abdominal discomfort and pain, suggestive of intestinal obstruction, recurred after operation. A tubular mass was palpable in the right lower quadrant. Computed tomography enterography scan identified suspicious intestinal intussusception, while Tc-99m pertechnetate scintigraphy revealed a cluster of strip-like abnormal radioactivity in the right lower quadrant. On exploratory laparotomy, a tubular-shaped ileal duplication cyst was found arising from the mesenteric margin of the native ileal segment located 15 cm proximal to the ileocecal valve. Ileectomy was performed along with the removal of the duplication disease, and the end-to-end anastomosis was done to restore the gastrointestinal tract continuity. Pathological examination showed ileal duplication with ectopic gastric mucosa. The patient experienced an eventless postoperative recovery and remained asymptomatic within 2 years of postoperative follow-up.

This report describes an acute presentation of obstructive jaundice, with a clinical picture of cholecystitis. A primary carcinoid tumour in the terminal ileum with hepatic secondaries was found to be the cause. Additionally, in the terminal ileum was a closely associated lipoma leading to an ileo-caecal intussusception. There are few such cases in the literature, particularly in the absence of any changes in bowel habit or lower abdominal pain. The majority of cases of intussusception in clinical practice occur in the paediatric population. Of the small numbers (<5%) that occur in adulthood, the underlying aetiology is most commonly a primary adenocarcinoma, with a far smaller number being attributable to lipoma, lymphoma and polyps.
Heterotopic, aberrant or ectopic pancreas is defined as the presence of pancreatic tissue in topographic anomaly, with no anatomical, neural or vascular connection to the normal pancreas. It is a rare condition found mainly in stomach, duodenum and jejunum. Ileal heterotopic pancreas is an uncommon condition and has been rarely reported in children so far. Hereby we report a case of heterotopic pancreas presenting as ileal poyp leading to ileoileal intussusception in a 12 year child.
Intussusception is a condition found primarily in the pediatric population. In the adult population, however, intussusception is usually due to a pathological process, with a higher risk of bowel obstruction, vascular compromise, inflammatory changes, ischemia, and necrosis. Radiographic and sonographic evidence can aid in the diagnosis. Surgical intervention involving resection of affected bowel is the standard of care in adult cases of intussusception.
We present the case of a 21-year-old female who presented to the Emergency Department with diffuse cramping abdominal pain and distention. Workup revealed ileocecal intussusception, with a prior appendectomy scar serving as the lead point discovered during exploratory laparotomy. We also present the case of a 66-year-old male, who presented with one week of intermittent lower abdominal pain associated with several episodes of nausea and vomiting. Workup revealed ileocolic intussusception secondary to adenocarcinoma of the right colon, confirmed upon exploratory laparotomy with subsequent right hemicolectomy.
In the adult population, intussusception is usually caused by a lead point, with subsequent telescoping of one part of the bowel into an adjacent segment. While intussusception can occur in any part of the bowel, it usually occurs between a freely moving segment and either a retroperitoneal or an adhesion-fixed segment. The etiology may be associated with pathological processes such as carcinoma or iatrogenic causes, such as scars or adhesions from prior surgeries. The cases presented here demonstrate important etiologies of abdominal pain in adult patients. Along with gynecological etiologies of lower quadrant abdominal pain in female patients, it is important for the emergency physician to expand the differential diagnosis to include other causes, such as intussusceptions, especially given the symptoms that could be associated with bowel obstruction.
AIM: To give an overview of the literature on intussusception due to inflammatory fibroid polyp (IFP).
METHODS: We present a new case of ileal intussusception due to IFP and a literature review of studies published in English language on intussusception due to IFP, accessed via PubMed and Google Scholar databases. For the search, the keywords used were: intussusception, IFP, intussusception and IFP, intussusception due to IFP, and IFP presenting as intussusception. The search covered all articles from 1976 to November 2011.
RESULTS: We present a 38-year-old woman who was admitted 10 d after experiencing abdominal pain, vomiting, and nausea. Ultrasonography demonstrated small bowel intussusception. An ileal intussusception due to a mass lesion 50 cm proximal to the ileocecal junction was found during laparotomy. Partial ileal resection and anastomosis were performed. A diagnosis of ileal IFP was made based on the immunohistochemical findings. In addition, a total of 56 reports concerning 85 cases of intussusception due to IFP meeting the aforementioned criteria was included in the literature review. The patients were aged 4 to 81 years (mean, 49 ± 16.2 years); 44 were women (mean, 51.8 ± 14.3 years) and 41 were men (mean, 46 ± 17.5 years). According to the location of the IFP, ileal intussusception was found in 63 patients, while 17 had jejunal, three had colonic, and two had ileojejunal intussusception.
CONCLUSION: Although IFPs are rare and benign, surgery is the only solution in case of intestinal obstruction. Differential diagnosis should be made via immunohistochemical examination.

Adult intussusception is a rare entity accounting for only 5% of all intussusceptions and causes approximately 1% of all adult intestinal obstructions. Unlike paediatric intussusceptions which are usually idiopathic, there is usually a lead point pathology which might be malignant in up to 50% cases. We present an unusual case of adult intussusception which was not diagnosed on any investigation including computerized tomographic (CT) scan and magnetic resonance imaging (MRI). It was a case of ileo-ileo-cecal intussusception caused by a large lipoma 38 mm × 43 mm × 61 mm. It was treated by emergency laparotomy for acute intestinal obstruction. A conservative resection with ileostomy was performed with good postoperative recovery.
Intussusception is the most common cause of intestinal obstruction in infants and children. This condition is frequent in children and presents with the classic triad of cramping abdominal pain, bloody diarrhoea and a palpable tender mass. Small bowel intussusceptions are much less common, with jejuno-ileal and duodeno-jejunal intussusceptions being the rarest types of all. Multiple simultaneous intussusception is a peculiar variety of intussusception. The authors report the simultaneous occurrence of jejuno-jejunal and ileo-ileal intussusception in a patient. As this is an extremely uncommon entity, it is being reported with a brief review of the relevant literature.
Inflammatory fibroid polyps are rare benign tumors of the gastrointestinal tract with the gastric antrum being the most common site, followed by the ileum. Histogenesis is still unknown and controversial. Inflammatory fibroid polyps are one of the rare benign conditions leading to intestinal obstruction in adults.
A 54-year-old Caucasian man presented with acute abdomen pain and a two month history of intermittent cramping and lower abdominal pain. Computed tomography imaging demonstrated a partial intestinal obstruction in the location of the terminal ileum. An ileo-ileal intussusception due to a mass lesion 15 cm proximal to the caecum was found on exploratory laparotomy. Intussusception was spontaneously reduced during exploration and a wedge resection was performed to the affected bowel segment. Histopathologic examination showed the mass to be an inflammatory fibroid polyp.
Although inflammatory fibroid polyps are rare and benign, in the case of intestinal obstruction the only solution is a surgical approach.
Intussusception is an uncommon cause of abdominal pain in adults and poses diagnostic challenges for emergency physicians, due to its varied presenting symptoms and time course. Diagnosis is thus often delayed and results in surgical intervention due to the development of bowel ischaemia. We report on a young patient who presented with an ileo-ileal intussusception in whom there were no underlying lesions identified as a causal factor.
Gastrointestinal stromal tumors (GIST) are mesenchymal tumors occurring anywhere along the gastrointestinal tract and are believed to originate from the interstitial cells of Cajal. They commonly arise in the stomach or small intestine. The usual growth pattern is exophytic invading adjacent organs or perforation into the peritoneal cavity which may result in bleeding or obstructive symptoms. Intussusception and obstruction is a very uncommon presentation of these lesions because of their tendency to grow in an extraluminal fashion. We report an unusual case of 59 yrs old man presenting with acute small bowel obstruction, which on exploration was found to be due to ileo-ileal intussusception and the lead point of intussusception was a tumor, which was histologically diagnosed as GIST

This 67-year-old woman, with numerous previous abdominal operations, presented to her general practitioner 3 years ago with generalised abdominal pain and diarrhoea. With unremarkable haematology tests and a CT scan at that time she was given the diagnosis of irritable bowel syndrome. During the next 3 years her symptoms continued intermittently and now associated with vomiting and weight loss. This time both a barium follow-through followed by a CT scan demonstrated a small bowel intussusception. A laparotomy was done but surprisingly no intussusception was found, only a single adhesional band which was divided. She was discharged 5-days postoperative but re-admitted 3 days later with abdominal discomfort, bloating and vomiting. A repeat CT scan again showed the presence of a small bowel intussusception and a second laparotomy was performed, this time demonstrating a jejuno-ileal intussusception which was reduced and resected with primary anastomosis. Her postoperative course was without incidents.
Intussusception is defined as the telescoping of a segment of the gastrointestinal tract (intussusceptum) into an immediately adjacent distal bowel (intussuscipiens). Intussusception is a relatively rare cause of intestinal obstruction in adults. Unlike in children, a lead point is present in 90% of adult cases. The most common causes of small bowel intussusception are benign, usually hamartomas, lipomas, inflammatory polyps, adenomas and leiomyomas, in contrast to the large intestine where malignant tumors, usually adenocarcinomas, are more common. The clinical presentation of adult intussusception is non-specific with variable manifestations, predominantly those of intestinal obstruction, often making the diagnosis a challenge. The onset of symptoms may be acute, intermittent or chronic. We present a rare case of an ileal fibroma presenting with intussusception. A 43-year-old woman presented to our outpatient clinic with a history of recurrent abdominal pain. The clinical presentation and CT scan findings led to the diagnosis of ileoileal intussusception. Subsequently she underwent laparotomy which revealed an ileal fibroma as the lead point of the intussusception. Surgical exploration remains essential for diagnosis and treatment since in the majority of cases a pathologic lead point is identified. Ileal fibroma is an uncommon benign neoplasm of the small bowel and must be considered in the differential diagnosis for small bowel intussusception.

A 5-year-old girl presented with a 3-day history of pain and distension of abdomen, bilious vomiting, bleeding per rectum and a hard lump in the left iliac fossa. Intussusception was clinically diagnosed. On exploratory laparotomy, trichobezoar showing cast of the stomach, duodenal C-loop and tail were extracted. The stomach cast was impacted at the distal ileum, while its tail traversed the ileum, ileocecal valve and extended up to the hepatic flexor. At the site of impaction, a large ileal perforation, covered by bezoar was present. Hence, x-ray did not reveal pneumoperitoneum. There was no evidence of trichobezoar in the stomach. Perforation was exteriorised as loop ileostomy. She was of normal intelligence. Psychological evaluation of the child was performed and a behaviour therapy was advocated. Ileostomy closure was done after 2 months. At 6 months follow-up, no recurrence was found.
Adult intussusception caused by an inverted Meckel diverticulum is rare. We report a 55-year-old Japanese man with intussusception. He was admitted to our hospital with vomiting and abdominal pain. The abdomen was hard with tenderness and muscle guarding. Computed tomography scanning demonstrated a typical inhomogeneous target-shaped mass in the right abdomen. We diagnosed intussusception and performed emergency surgery. At laparotomy, ileocolic intussusception was observed and the ileocecal segment was resected. The surgical specimen comprised an 84 cm segment of resected ileocecum with an elongated polypoid lesion measuring 11 × 2 cm within the ileal lumen. Histopathological examination demonstrated that the polypoid lesion was an inverted Meckel diverticulum. Postoperatively, the patient made an uneventful recovery.

Intussusception is a common cause of intestinal obstruction and colicky abdominal pain in the children, particularly infants, the commonest being the ileocolic variety with colocolic variety being a very rare entity. We present a case of colocolic intussusception in a 13-year-old boy which is otherwise seen in adults, precipitated by colonic malignancies. The patient presented with acute abdominal pain and bleeding perrectum with obstipation for 7 days. Preoperative USG abdomen was normal, and abdominal X-rays showed multiple air fluid levels. Intraoperative findings included a polypoidal growth in the descending colon as the leading point with the formation of a colo-colic intussusception. Following reduction and segmental resection, histopathology reported mucinous adenocarcinoma of colon which is also a rarity in pediatric age group. This case has been compared with previous cases reported in the literature.
We present a rare case of adult intussusception due to cecal lymphangioma. A 30-year-old female was admitted to our hospital with abdominal pain and a palpatable mass on the right lower quadrant. Preoperative radiologic studies by ultrasound and computed tomography showed ileocolic intussusception with a multiseptated cystic tumor as a leading point on the cecum. An ileocecectomy was performed, and the postoperative course was uneventful. Histopathology showed a cecal lymphangioma. Although endoscopic polypectomy or endoscopic mucosal resection is recommended for pedunculated or semi-pedunculated colonic lymphangiomas less than 2 cm in size, it is proper to treat large or symptomatic colonic lymphangiomas with limited a bowel resection or a tumor resection.

Intussusception in adults accounts for less than 5% of all intussusceptions. It occurs when a segment of intestine invaginates into itself.
PRESENTATION OF A CASE
We report a case of ileocolic intussusception in an adult caused by a giant ileal lipoma.
Intussusceptions can be classified as ileocolic, ileocecal, colo-colic and ileo-ileal. Most are due to neoplasms (60% malign and 24–40% benign). In the colon, the possibility of malignancy is higher than in small intestine.
Lipomas are the most common benign mesenchymal intestinal tumors, accounting for less than 5% of all gastrointestinal tumors. They are more frequent in colon than small intestine. Small lipomas (less than 2 cm) are usually asymptomatic. Larger lesions may produce symptoms such as abdominal pain, obstruction or intussusception. Lipomas can be diagnosed with endoscopy, capsule endoscopy, barium enemas, CT and US.
Intussusceptions in adults is a rare condition, most of them are caused by a malign neoplasms followed by benign neoplasms. US and CT are useful for diagnosis. Surgery is mandatory.
