Ileal intussusception due to a parasite egg: A case report

Ileal intussusception is the invagination of the small intestine within itself and accounts for 1% of cases of acute obstruction. However, physicians do not initially consider intussusception as a possible diagnosis of obstruction due to its rarity in adults. Herein, we report the case of a 22-year-old male who was admitted to the Emergency Department with continuous abdominal pain. Ultrasonography and computed tomography revealed an ileal intussusception. The patient underwent surgical removal of the segment of the small bowel. Unexpectedly, pathology revealed that the invagination occurred due to a parasite egg, with features suggestive of Schistosoma species. Schistosomiasis, although considered a parasitic disease in tropical countries, is not absent from Europe and though it is highly improbable, it may be responsible for cases of intussusception in adults.     

Intussusception due to rectal adenocarcinoma in a young adult: A case report

An intussusception due to colonic adenocarcinoma has sometimes been reported. However, to the best of our knowledge, reports of intussusception due to rectal adenocarcinoma are extremely rare. In this report, the case of a young man with rectal adenocarcinoma causing intussusception is described. A 24-year-old man visited a hospital complaining of abdominal pain, and an upper rectal cancer was diagnosed by colonoscopy. Computed tomography showed intussusception caused by a large tumor in the pelvis and absence of distant metastases. Locally advanced rectal cancer causing intussusception was diagnosed, and a low anterior resection was performed. Intraoperatively, repair of the invagination could not be accomplished easily; therefore, the repair was abandoned. Instead, the tumor was removed en bloc to avoid dissemination of the cancer. Histopathologically, the tumor was diagnosed as a poorly differentiated adenocarcinoma, pStage IIA. The patient has no evidence of recurrence at 10 mo after the operation.     

Acute Jejunogastric Intussusception—A Case Report

Abstract: Acute jejunogastric intussusception is often a life-threating complication of gastric surgery. The present case of acute retrograde jejunogastric intussusception occurred twenty years after a Billroth II partial gastrectomy. Acute pancreatitis was misdiagnosed primarily became of a low suspicion index. The diagnosis was establised by gastroscopy and radiography. During surgery, an intussusception of 30 cm of the efferent jejunum was reduced. Jejunogastric intussusception should be strongly suspected in all patients who Present with epigastric pain, vomiting, hematemesis, abdominal mass, or/and high intestinal obstruction after previous gastric surgery.     

Adult descending colocolic intussusception caused by a large lipoma

Adult intussusception is uncommon and varies considerably from the more common occur rence of this disorder in infants and children. Although lipoma represents the most common benign tumor of the colon, it is a relatively rare cause of gastrointestinal symptoms. A rare case of adult intussusception of the descending colon caused by a giant lipoma is presented and discussed.     

Colo-colonic intussusception in an adult: an unusual presentation of perforated diverticulitis

We describe an unusual case of acute bowel obstruction caused by a colo-colonic intussusception associated with perforated sigmoid diverticulitis in an adult. Radiographic and pathologic features of the colo-colonic intussusception are presented. A review of the recent literature with regard to the clinical symptoms, signs, diagnosis, etiology, and treatment of colo-colonic intussusception is provided. Colo-colonic intussusception is a rare cause of acute intestinal obstruction in the adult and is usually associated with a malignancy. Treatment should include primary resection without attempts at reduction of the intussusception. Received: 26 February 2000 / Accepted in revised form: 10 June 2000     

Ileocolic intussusception in an adult

Two weeks after appendectomy a right hemicolectomy was performed on a 35-year-old man because of an ileocolic intussusception. The appendiceal stump was the leading point of the intussusception. Ileocolic intussusception is a very rare complication after appendectomy. The clinical symptoms, diagnostic features, and mode of treatment are discussed.     

Endoscopic treatment of a large colonic polyp as a cause of colocolonic intussusception in a child

Colocolonic intussusception is an uncommon cause of intestinal obstruction in children. The most common type is idiopathic ileocolic intussusception. However, pathologic lead points occur approximately in 5% of cases. In pediatric patients, Meckel's diverticulum is the most common lead point, followed by polyps and duplication. We present a case of recurrent colocolonic intussusception which caused colonic obstruction in a 10-year-old boy. A barium enema revealed a large polypoid mass at the transverse colon. Colonoscopy showed a colonic polyp, 3.5 centimeters in diameter, which was successfully removed by endoscopic polypectomy.     

Adult intussusception caused by cystic lymphangioma of the colon： A rare case report

We experienced a case of intussusception caused by cystic lymphangioma of the colon in a 32 years old female who was admitted to our hospital for the chief complaint of bloody stool. In the colonoscopic examination, cystic mass with stalk which had smooth mucosal surface was noted at the descending colon. Abdominal ultrasonography and computed tomography revealed left colon intussusception with a multilocular cystic tumor as a leading point. Emergent operation was performed. On the histopathologic examination, the cystically dilated spaces lined by endothelium and septated by fibrous septa were present. The pathological diagnosis was cystic lymphangioma of the colon. Although intussusception due to lymphangioma in an adult are rare, it should be taken into consideration that it is possible diagnosis.     

Reversible protruded lesion regarded as idiopathic appendiceal intussusception

A patient with a reversible protruded lesion regarded as idiopathic appendiceal intussusception was investigated in this study. The patient was a 78‐year‐old male, who consulted our department as a result of positive occult blood in his stool sample. There was no associated pain, nausea, vomiting, fever, chill or anorexia. He had no prior surgical history. Total colonoscopy detected a sigmoidal polyp and a protruded lesion in the caecum. The protruded lesion (about 12 mm in diameter) covered with normal mucosa was diagnosed as a benign submucosal tumor at that time. The periodic follow‐up colonoscopy showed an orifice on top of the protuberance. Further detailed observation revealed that the lesion reduced by itself, and resulted in showing a normal orifice of the appendix; however, afterwards it protruded again. These observations led to the diagnosis of the lesion as type B of Atkinson's classification in appendiceal intussusception. To our knowledge, approximately 200 cases of appendiceal intussusception have been documented in scientific reports worldwide. In Japan, only 10 cases of idiopathic appendiceal intussusception have been described. This case is considered to be important for presenting the initial stage of the complete intussusception of the appendix.     

Preoperative sonographic diagnosis of McSwain type V appendiceal intussusception: A case report (with video)

Rationale:Appendiceal intussusception is a rare disease. The definite preoperative diagnosis of appendiceal intussusception is rare and challenging. Here, we present a case of McSwain type V appendiceal intussusception in a 10-year-old boy. To our best knowledge, this is the first case report of a type V appendiceal intussusception that was preoperatively confirmed with sonography. Here, we have described in detail the ultrasound features and differential diagnosis of this rare disease.Patient concerns:A 10-year-old boy presented with 3 days of recurrent intermittent mild abdominal pain. The result of ultrasonography suggested an ileocolic intussusception and a therapeutic air-contrast enema was requested to reduce the intussusception but failed at a local hospital.Diagnoses:Physical exam revealed mild tenderness in the lower right quadrant of the abdomen. However, ultrasonography showed a target-sign in cross section and a finger-like appearance in the longitudinal view. A diagnosis of McSwain type V appendiceal intussusception was made.Interventions:The patient underwent an appendectomy after successful manual reduction on laparotomy. The appendix was successfully resected.Outcomes:Intraoperatively, the appendix was completely inverted in the cecum, and the preoperative sonographic findings were confirmed. During follow-up, there were no signs of recurrence.Lessons:Pre-operatively, on ultrasound a type V appendiceal intussusception is usually misdiagnosed as an ileocolic intussusception. Radiologists must execute caution to avoid over reliance on the sonographic findings of intussusception, especially when there is a mismatch with clinical symptoms. It is especially important to accurately understand the surgical-anatomic configuration of type V appendiceal intussusception that creates a “target-sign” and a “finger-like” layout on ultrasonography.     

Ileocolic intussusception in adult due to malignant lymphoma in the cecum with intramural metatasis

A rare adult case of intussusception caused by malignant lymphoma of the cecum with intramural metastasis is reported. The patient was a 24-year-old man. Ileocolic intussusception was diagnosed by characteristic findings on abdominal computed tomography. Endoscopic examination revealed a massive protuberant tumor, 3 cm in diameter, and a semipedunculated polyp, 1 cm in diameter, in the cecum, which had caused the ileocolic intussusception. Endoscopic biopsy specimens failed to yield a definitive diagnosis histologically, but right hemicolectomy with lymph node dissection was performed. On histologic examination of the surgical specimens, both the tumor and the polyp were diagnosed as diffuse lymphoma of medium-sized cell type, and no lymph node involvement was found. The patient responded well to surgical and chemotherapeutic treatment, and has had no recurrence of malignant lymphoma in the 2 years since the surgical treatment. This was a very rare case of an intussusception in an adult patient due to malignant lymphoma in the cecum with intramural metastasis and without lymph node involvement.     

Intussusception in an adult patient with severe hyperglycaemia--a case report.

AIMS: To report a case of adult intussusception associated with and possibly induced by acute hyperglycaemia. METHODS: We present the first case report of adult intussusception with severe hyperglycaemia. Clinical and laboratory data together with radiological findings are presented with a brief review of the literature. RESULTS: A 20-year-old man with no past medical history presented with abdominal pain for 2 days. The patient was severely hyperglycaemic with blood glucose of 72.7 mmol/l (normal 3.3-6.1 mmol/l), a pH of 7.2 and serum potassium of 6.5 mmol/l (normal 3.5-5.0 mmol/l). He had a computed tomography (CT) scan of the abdomen that revealed small bowel intussusception. Upon treatment of his hyperglycaemia, the patient's abdominal pain completely resolved. Follow up abdominal CT revealed complete resolution of the previously detected intussusception. CONCLUSION: Clinicians should be aware of the potential for the occurrence of intussusception in severely hyperglycaemic patients. Correction of hyperglycaemia could lead to resolution of the intussusception without surgical intervention. Possible effects of hyperkalaemia and/or acidosis on gastrointestinal motility should also be considered.     

Is rectal intussusception a cause of idiopathic incontinence?

PURPOSE: The cause of rectal intussusception in patients primarily dominated by symptoms of anal incontinence has not been fully elucidated, especially for patients with idiopathic incontinence. METHODS: Between 1991 and 1996, 51 patients referred with a diagnosis of idiopathic incontinence were prospectively evaluated by standard questionnaire, clinical examination, defecography, and anal manometry. Fourteen female patients were identified with rectal intussusception and were treated by transabdominal rectopexy. Postoperatively, clinical assessment and anal manometry were performed at regular intervals. RESULTS: Continence was improved after rectopexy (P<0.01). The postoperative increases in the anal resting pressure, maximum squeeze pressure, and maximum tolerated volume were not statistically significant. CONCLUSIONS: Rectopexy improved anal incontinence in patients with rectal intussusception. The cause of rectal intussusception in anal incontinence could not be explained by functional improvement of the internal anal sphincter tone or an increase in the maximum tolerated volume. Rectal intussusception may be a cause of idiopathic incontinence in patients; however, larger prospective studies are required to support this concept.     

Gastroduodenal intussusception due to gastric schwannoma treated by billroth Ⅱ distal gastrectomy:One case report

Schwannomas are rarely observed in the gastrointestinal tract.The most common symptoms of a gastric schwannoma are abdominal pain or dyspepsia,gastrointestinal bleeding,and an abdominal mass.Many gastric schwannomas are asymptomatic and are discovered incidentally or at postmortem.The diagnosis of a schwannoma is based on immunohistochemical positivity for S-100 protein.Wepresent a case report of a rare complication of gastric schwannoma causing gastroduodenal intussusception that was successfully managed by a BillrothⅡdistal gastrectomy.In this rare case,the patient had intermittent,colicky abdominal pain,nausea,and vomiting for over 4wk accompanied by a weight loss.A diagnosis of gastric intussusception was made by computed tomography.A BillrothⅡdistal gastrectomy was then performed,and complete en bloc removal(R0 resection)was achieved.Pathology confirmed a gastric schwannoma through positive immunohistochemical staining for S-100 protein.     

Intussusception Caused by Subserosal Lipoma of the Ileum

Abstract: In this study a case of ileal subserosal lipoma with ileocolic intussusception is reported, together with a review of the literature. The patient, a 37-year-old female, was admitted with melena and abdominal pain. A complete blood cell count revealed microcytic anemia. An ultrasonography and CT scan revealed ileocolic intussusception. On colonoscopy, a tumor was seen at the site of the ileocecal valve. Subsequently, the tumor was retracted mechanically using an endoscope. An ileogram taken after retraction revealed the tumor to have been about 50 cm proximal to the ileocecal valve. In addition to the tumor, 6 cm of the ileum was resected. The tumor was 2.5 cm in diameter; the histological diagnosis was subserosal lipoma of the ileum. This is a rare case of intussusception due to an intestinal lipoma diagnosed by various visual examinations before surgery.     

A High Incidence of Intussusception Revealed by a Retrospective Hospital-Based Study in Nha Trang,Vietnam between 2009 and 2011

Rotavirus is a leading cause of severe diarrhea among children worldwide. Thus, the World Health Organization recommended including rotavirus vaccines in national immunization programs. One concern about rotavirus vaccine, however, is a possible association with intussusception. Thus, it is crucial to know the baseline incidence of intussusception in the first year of life. A study conducted in Hanoi, Vietnam showed that the incidence of intussusception was the highest in the world. This retrospective cross-sectional study was undertaken to determine the incidence of intussusception among children <5 years of age in Nha Trang, Vietnam. Hospital charts between 2009 and 2011 were reviewed in Khanh Hoa Provincial General Hospital where virtually all cases of intussusception occurring in the city were assumed to have been encountered. The incidence of intussusception among children <1 year of age was 296 per 100,000 person-years (95% confidence interval [CI]: 225–382), and that among children <5 years of age was 196 per 100,000 person-years (95% CI: 169–226), confirming the high incidence of intussusception in Vietnam. Nevertheless, there was no intussusception in the first three months of life. We therefore recommend that the first dose of any rotavirus vaccine be administered to infants between 6 and 12 weeks of age.

Malignant lymphoma in the ileocecal region causing intussusception

A 67-year-old female was admitted with diarrhea. Preoperatively, we diagnosed intussusception due to malignant lymphoma in the ileocecal region by image and colonoscopic examinations. We resected the right hemicolon for the tumor, which was located mainly in the cecum, causing intussusception. The stenotic terminal ileum free of the tumor was invaginated within the cecum with infiltrating tumor, thus showing the appearance of an anthill. The growth of the tumor corresponded with Wood's constrictive type, in which intussusception rarely occurs.     

Intussusception and leiomyosarcoma of the gastrointestinal tract in a pediatric patient

Summary Intestinal leiomyosarcoma is a rare tumor in infants and children; only 46 cases have been reported in the English literature. Presenting signs and symptoms include abdominal pain and gastrointestinal obstruction and bleeding. We describe a neonate with the unique presentation of ileocecal intussusception accompanying an ileal leiomyosarcoma. In contrast to adult patients, where intussusception is associated with smooth muscle tumors in 30% of cases, leiomyosarcoma and subsequent intussusception is rare in infancy and childhood. The overall prognosis for long-term survival is similar for both pediatric and adult patients with leiomyosarcoma of the intestinal tract, with a five-year survival in reported cases of 53% and 40%, respectively.     

Colo-colic intussusception associated with Henoch-Schönlein purpura in adults

Henoch–Schönlein purpura (HSP) is often seen in childhood and is a self‐limiting illness, and complication with intussusception is rare in adults. The case is reported of a 74‐year‐old man who was diagnosed with intussusception with HSP by ultrasonography on day of admission. Conservative therapy was started. However, his abdominal symptoms worsened, so he underwent laparotomy 3 days after admission. Histological study of the resected specimens demonstrated necrosis in the intussuscepted colon induced by HSP vasculitis. Bowel necrosis with intussusception in adult HSP is rare and might easily be overlooked. Thus special attention should be paid to gastrointestinal manifestations and, in an abdominal emergency, timely surgical intervention is life‐saving.
