Prograde and retrograde intussusception: A rarity in Peutz-Jeghers syndrome

A 30-year-old woman presented with subacute intestinal obstruction. Clinical evaluation and radiological studies pointed toward an enteroenteric intussusception with intestinal polyps. Exploratory laparotomy revealed a retrograde intussusception mass acting as a lead point for a second prograde jejuno-jejunal intussusception. Resection and anastomosis of the involved segment was done. Histopathology revealed the presence of hamartomas. The patient was diagnosed with Peutz-Jeghers syndrome. The rarity of such a case is highlighted, and the diagnostic challenge it poses is discussed.     

Minimal access surgery for adult intussusception with subacute intestinal obstruction: a single center's decade-long experience

INTRODUCTION: In adults, 1% to 5% of bowel obstruction is caused by intussusception. In adult intussusception, there will be a demonstrable cause in 90% of cases, acting as the lead point. Laparoscopy is becoming more and more popular in its management. We present our series of intussusception in adults managed laparoscopically. MATERIALS AND METHODS: Between 1996 and 2006, we have treated 12 adults with intussusception who presented with acute or subacute intestinal obstruction. Computed tomographic scan confirmed the diagnosis in all cases. Laparoscopic-assisted resection with primary anastomosis was successfully performed for all cases. RESULTS: Males were more common, average being 38 years. Two patients had colonic carcinoma, as the leading point and the rest were benign tumors. There were no conversions or anastomotic leaks in any patient. DISCUSSION: The basic principles of surgery involve straightening or removing the involved section of bowel. The outcome of surgery depends on the stage of the intussusception at diagnosis and the underlying cause. If no underlying cause is found in these cases, no specific treatment is required. With early treatment, the outcome is generally excellent. CONCLUSIONS: Laparoscopy is a valuable diagnostic and therapeutic tool in the management of adult intussusception. It provides all the benefits of minimal access surgery.     

Intussusception in adults: a retrospective study

Objective Intestinal intussusception in adult patients is rare. In contrast with paediatric patients, it is usually secondary to a definable lesion, often malignant. The purpose of this study was to determine the causes and the management of intussusception in adult patients. Method A retrospective review was performed looking at patients over 18 years with intestinal intussusception who were admitted to a tertiary university hospital from 1997 to 2007. Result There were 16 patients (out of whom 10 were female subjects) of mean age 49 years (range 19–76). All presented with abdominal pain and in seven (46.6%) patients, this was acute. The diagnosis of intussusception was correctly made preoperatively in eight (50%) patients. Six (37.5%) patients had the lead point for the intussusception at the ileocaecal valve, five (31.25%) in the small bowel and five (31.25%) had a colonic lead point. An anatomical cause was found in 14 (87.5%). In two (12.5%), the intussusception occurred in the postoperative period without any definable lesion. Half the patients had a malignant neoplasm. All patients underwent surgery. In 14 (87.5%) patients, this was by resection and in two (12.5%), a reduction with no resection was carried out. Conclusion The features of intussusception may be nonspecific and the diagnosis is often made only during laparotomy. An identifiable organic lesion is present in most cases. En bloc resection is recommended for ileocaecal and colocolic intussusception.     

Adult colo-colonic intussusception caused by congenital bands: A case report and literature review

IntroductionIntussusception refers to the telescoping of a segment of bowel into the lumen of an adjacent segment. While pediatric intussusception is common and generally idiopathic, adult intussusception is exceedingly rare and is usually attributable to a pathologic lead point.Presentation of case37-year-old man who presented with abdominal pain, and was preoperatively diagnosed with a colo-colonic intussusception. Intraoperatively, the lead point was found to be congenital bands, and there was no evidence of underlying malignancy. He underwent a laparoscopic-assisted extended right hemicolectomy with side-to-side ileo-colic anastomosis.DiscussionColo-colonic intussusception is a rare cause of intestinal obstruction in adults. Patients generally present with subacute abdominal pain and obstructive symptoms, rendering the clinical diagnosis challenging. Computed tomography has been shown to be the most accurate diagnostic imaging modality. Due to the high incidence of underlying malignancy in adult colo-colonic intussusception, en-bloc resection of the involved bowel segment remains the standard of care.ConclusionCongenital bands can serve as a lead point in colo-colonic intussusception, particularly in younger adults. Prompt surgical intervention remains paramount to limit morbidity.     

Adult intussusception: experience in Singapore

Introduction: Gastrointestinal intussusception is an uncommon clinical entity in adults and is interestingly distinct from its paediatric form. In adults an identifiable lead lesion is found in the majority of cases, of which a significant percentage are malignant. Its treatment is thus different from that of paediatric intussusception. The present study reviews our experience of treating adult intussusception. Methods: A retrospective review of patients with a postoperative diagnosis of gastrointestinal intussusception between January 1997 and December 2002 was conducted. All patients under the age of 18 and cases of rectal prolapse were excluded. Results: During the 5‐year period, there were nine cases of intussusception. There were four male and five female patients, with a mean age of 63.8 years (range 37?85 years). Less than half of the patients (44.4%) presented with acute symptoms. The most common symptoms were abdominal pain and distension. The symptoms were intermittent in 77.8% (7 of 9) of patients. Only two patients had a palpable abdominal mass, while another had signs of acute intestinal obstruction. Computed tomography was the most useful imaging modality, identifying intussusception in six out of six patients. Eight patients had lead lesions occurring at the ileocaecal junction resulting in ileo‐colonic intussusception. Of these eight, four were malignant (two adenocarcinomas and two lymphomas). There was one sigmoid‐rectal intussusception secondary to adenocarcinoma. All patients were treated operatively. Seven patients were treated with en bloc resection. Conclusion: Although uncommon, surgeons need to be aware of the epidemiology and treatment options for adult intussusception. The symptoms and signs are often non‐specific and the surgeon might be faced with the diagnosis only at laparotomy. Computed tomography is the most useful imaging modality. An identifiable organic lesion is present in most cases, of which more than 50% are malignant (especially in the large bowel). Operative treatment is thus prudent. En bloc resection is recommended for ileo‐colonic and colo‐colonic intussusception. There is, however, a role of initial reduction in selected patients with ileo‐ileal intussusception.     

Ileocolic Intussusception - A rare cause of acute intestinal obstruction in adults; Case report and literature review

Colonic Intussusception although common in children, is a rare cause of acute intestinal obstruction in adults. The etiology, clinical presentation and management of this condition is different in adults as compared to children. Pre-operative diagnosis is usually difficult due to the non specific and intermittent nature of the symptoms. CT scan can be a helpful adjunct in establishing the diagnosis. We present a case report of adult ileocolic intussusception with classical radiological signs and operative findings. A brief literature review is also presented with emphasis on the controversy of reduction of the intussusception before resection.     

Caeco-colic intussusception in an adult: a rare case report

Intussusception is common in children but rare in adults. Caeco-colic intussusception is an uncommon cause of intestinal obstruction in adults. Very limited information is available about the role of colonoscopy in diagnosis of intussusception in the literature. We present a case of caeco-colic intussusception in a 50-year-old male who presented with the complaints of pain in abdomen and a lump in the right hypochondrium. Colonoscopy and contrast studies revealed the diagnosis of intussusception. Abdominal computed tomography (CT scan) is considered as the most sensitive investigation to diagnose intussusception at present, whereas colonoscopy is sparingly used to diagnose intussusception. In this patient, colonoscopy not only established the diagnosis and malignant nature of the lead point, but also guided the definitive extent of surgical resection. CT scan offers a presumptive diagnosis as compared to the definitive diagnosis of intussusception by colonoscopy. In adult intussusception, colonoscopy can be considered as a complimentary investigation to other diagnostic modalities. Hence regular use of colonoscopy in adult intussusception should be encouraged where presentation is either subacute or chronic.     

Intussusception caused by dried apricot: A case report

INTRODUCTION

An unusual cause of intussusception due to small bowel obstruction secondary to dried apricot consumption was encountered. Phytobezoar small bowel obstruction is a rare, but interesting pathology that accounts for 2–4% of small bowel obstructions (18). Even rarer, is an intussusception caused by dried fruit ingestion. We present the case of a 56-year-old female that presented with an intussusception after she ingested a large amount of dried apricots.

PRESENTATION OF CASE

The patient is a 56-year-old female with a small bowel obstruction secondary to intussusception in the distal ileum. She was taken to the operating room for a celiotomy where an intussusception of the distal small bowel was found. An enterotomy was performed which revealed dried apricots as the lead point. The intussusception was successfully reduced and the apricots removed.

DISCUSSION

Small bowel obstruction due to intussusception can be caused secondary to malignancy, Meckel''s Diverticulum, benign neoplasm, and strictures. A less common cause for small bowel obstruction due to intussusception in adults is secondary to mechanical obstruction by bezoars. Risk factors for bezoar formation include previous gastric surgery, diabetes, and mastication problems.

CONCLUSION

Bezoars are an extremely rare cause of intussusception in adults. A high level of suspicion needs to exist in the presence of a history of eating dried fruit, history of gastric surgery, diabetes mellitus, and problems with mastication. Various treatment modalities exist to treat obstructions secondary to bezoars, including open reduction and removal of bezoar via enterotomy.     

Intussusception secondary to endometriosis of the cecum

INTRODUCTION

Intussusception in adults is a rare cause of bowel obstruction. Endometriosis of the bowel is also a rare entity that can be the cause of bowel obstruction. Here, we report a rare case of intussusception secondary to endometriosis of the cecum.

PRESENTATION OF CASE

A 40-year-old woman presented to the hospital with a one-week history of intermittent epigastric pain. On physical examination, there was a soft, round non-tender palpable mass in the right flank and abdominal computed tomography scan revealed an intussusception. We made the diagnosis of ileo-colic intussusception and performed ileocecal resection. The surgical specimen revealed a round submucosal cystic mass in the cecum and the histology showed endometriosis of the cecum.

DISCUSSION

Intussusception in adults is a rare entity present in just 1% of all patients with bowel obstruction, and 5% of all intussusceptions. In general, intussusception in adults has a pathologic lesion as the lead point and the lesion is a malignancy in 20–50% of the cases. Thus, the treatment of an intussusception in adults should be operative. Endometriosis of the bowel is a rare cause of intussusception. Small endometriosis lesions of the bowel are unlikely to cause symptoms; however, in patients presenting with bowel obstruction, urgent treatment is indicated.

CONCLUSION

Intussusception in an adult is a rare cause of bowel obstruction and intussusception caused by endometriosis is also rare. Although rare, the diagnosis of endometriosis as a cause of intussusception must be considered as part of the differential diagnosis.     

Predictive Factors of Malignancy in Adults with Intussusception

Introduction Adult intussusception is an unusual entity, and its etiology differs from that in pediatric patients. The aim of this study was to evaluate our experience of 60 adult patients with intussusception and determine if there are any preoperative factors predictive of malignancy. Methods The records of 60 adult patients (> 18 years of age) with a diagnosis of intussusception surgically treated at Singapore General Hospital and Changi General Hospital between 1990 and 2004 were retrospectively reviewed. The intussusceptions were classified as enteric or colonic. Preoperative predictive factors of malignancy were analyzed using univariate and multivariate analyses, and P < 0.05 was considered statistically significant. Results There were 60 patients with a median age of 57.5 years (range 21–85 years). Altogether, 34 (56.7%) patients were male, and there were 31 enteric and 29 colonic intussusceptions. A lead point was identified in 54 patients (90%). A total of 22 (36.7%) patients presented with intestinal obstruction, and the correct preoperative diagnosis of intussusception was made in 31 patients (51.7%). Computed tomography was the most useful diagnostic modality, correctly identifying an intussusception in 24 of 30 patients. A malignant pathology was present in 8 of 31 (26%) enteric versus 20 of 29 (69%) colonic intussusceptions. Age (P = 0.009), the presence of anemia (P < 0.001), and the site of the intussusception (P = 0.001) showed significant differences between the benign and malignant groups by univariate analyses. On multivariate analysis, intussusception in the colon (P = 0.004) and the presence of anemia (P = 0.001) were independent predictive factors of malignancy. Conclusions Adult intussusception is most commonly secondary to a pathologic lead point. The site of intussusception in the colon and the presence of anemia are independent preoperative predictors of malignancy. All colonic intussusceptions should be resected en bloc without reduction, whereas a more selective approach can be applied for enteric intussusceptions.     

Adult Intussusception of Appendicular Mucinous Cystoadenoma

Intussusception is a rare cause of adult intestinal obstruction. Clinical manifestations are not specific, which makes a preoperative diagnosis difficult to establish and often causes delay. We report a case of acute intestinal obstruction due to ileocolic intussusception. An emergency laparoscopy was performed revealing an obstructive mass at the ileocecal region resulting from an appendicular tumor. A right hemicolectomy was conducted. The pathologic examination of the resected sample concluded the mass comprised an appendicular mucinous cystoadenoma. We discuss the clinical features, preoperative diagnosis, and surgical strategies of adult intussusception, as well as the uncommon finding of an appendicular mucinous tumor as its causative lesion, with a review of the available literature.     

Heterotopic gastric mucosa leading to recurrent intussusceptions: Report of a case

Although most cases of intussusception during childhood are caused by viral enlargement of the Peyer’s patches, the remainder of the cases may be due to congenital anomalies, such as heterotopic gastric mucosa (HGM). This report presents a case of HGM in a 4-year-old boy. The patient presented with acute abdominal signs with a right lower quadrant mass. His medical history indicated three episodes of recurrent intussusceptions. The abdominal ultrasound examination detected an intussusception. A laparotomy revealed an ileocolic intussusception and reduction was accomplished. During exploration, an intraluminal mass in the ileum, which was the lead point, was discovered by palpation. An enterotomy showed a 2-cm-diameter crater-shaped mucosal thickening. An ileal resection and anastomosis was performed. The histopathological examination revealed HGM. Heterotopic gastric mucosa is supposed to be of vitellointestinal tract origin and may cause intussusception as being a lead point in the ileum. Despite its rarity, HGM should be considered in cases of recurrent intussusceptions and diagnostic studies should be performed. A laparotomy is required for the diagnosis and treatment in complicated cases. Surgical management should include reduction of the intussusception and careful manual examination of the ileum which may expose such pathology. An intestinal resection and anastomosis is sufficient to prevent complications.     

Laparoscopic treatment for intussusception of the small intestine in the adult

The term intussusception refers to a spontaneous invagination of a portion of the intestine into another bowel loop. Its incidence is higher in children, but in adults it causes 1% to 5% of intestinal obstructions. The diagnosis of intussusception in the adult is difficult due to the variability of the symptoms. The condition may be chronic, intermittent, or acute. Surgical intervention is necessary in all cases and in up to 90% of cases an organic lesion inside the invaginated part of the bowel is found to be the lead point. The laparoscopic approach offers both a diagnostic and therapeutic option. Laparoscopy may be used as the final diagnostic or therapeutic tool for intussusception in the adult.     

Inverted Meckel's diverticulum causing intussusception in an adult

Adult intussusception is rare, making-up only about 1% of the causes of bowel obstruction intussusception, secondary to an inverted Meckel's diverticulum, is also a rare occurrence. Chronic abdominal pain, lower gastrointestinal bleeding, and recurrent obstructive symptoms may lead to an unnecessary delay in diagnosis. This case report describes a rare cause of adult intestinal intussusception due to inverted Meckel's diverticulum. Intussusception was diagnosed on emergency ultrasound of the patient, who was successfully managed with surgery.     

Laparoscopic management of small bowel intussusception in a 16-year-old with Peutz-Jeghers syndrome

INTRODUCTION: 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. CASE REPORT: 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. RESULTS: 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. CONCLUSION: 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.     

Meckel's diverticulum in the adult

Meckel's diverticula were removed from 49 adult patients during a 15 year period. In 24 (49 per cent) of the patients the diverticulum was the cause of symptoms while in the remaining 25 it was an incidental finding at laparotomy. Of the symptomatic patients, 10 had acute inflammation of their diverticula, 8 presented with small bowel obstruction (in 4 cases due to fibrous bands) and 4 attended because of gross rectal bleeding; of the 2 remaining patients one was found to have intussusception of Meckel's diverticulum into the terminal ileum whilst the other had a nodule of calcified material lying within a partly gangrenous vitellointestinal duct. There was no operative mortality in the series. Heterotopic tissue was noted histologically in six Meckel's diverticula, all of which produced symptoms. The importance of considering a diagnosis of Meckel's diverticulum in the young adult presenting with acute small bowel obstruction or rectal bleeding is emphasized.     

Adult intussusception: Case report of recurrent intussusception and review of the literature

An unusual case of lymphoma is presented in which small bowel intussusception due to a lymphomatous nodule caused an acute abdomen, requiring small bowel resection. Four weeks later a second intussusception caused intestinal obstruction, necessitating a second laparotomy and bowel resection. The high incidence of malignant tumor in adult cases leads us to recommend primary resection without manual reduction in all but rectosigmoid and selected small bowel cases.     

Biliopancreatic Limb Obstruction in Gastric Bypass at or Proximal to the Jejunojejunostomy: A Potentially Deadly,Catastrophic Event

Background: Although unusual, but not rare, obstruction in the vicinity of the jejunojejunostomy in Roux-Y gastric bypass (RYGBP) can progress in a very short period of time to a life-threatening situation. Methods: Over a 10-year period in 1,174 RYGBP's, we have seen seven instances of acute and subacute partial to complete small bowel obstructions in the vicinity of the jejunojejunostomy, which can lead to acute gastric dilatation due to obstruction of the bilio-pancreatic limb. Signs and symptoms of the obstruction may include tachycardia, oliguria, hypotension, severe epigastric pain with or without a palpable mass in the epigastrium, chronic bile regurgitation and bilious vomiting, and a possible increase in serum amylase. Laboratory data otherwise has not been helpful, and although a palpable abdominal mass may be diagnostic, the best tools have been radiologic, i.e. the acute abdomen series, limited upper GI series in the patients that appear to be only partially obstructed, abdominal ultrasound and probably most importantly, CT of the abdomen. Results: In the seven cases presented, diagnoses included internal hernia, adhesions, an idiopathic spontaneous hematoma of the bowel wall and retrograde intussusception at the jejunojejunostomy. Conclusions: Since many surgeons who perform bariatric surgery are alone in their community, they should train their non-bariatric surgical colleagues and associates to be aware of these potential deadly problems.     

Suture knot forming the apex of an adult ileo-ileal intussusception: a case report

A revision laparotomy in an adult for early post-operative small bowel obstruction revealed retrograde ileo-ileal intussusception. The apex was formed by the suture knot from the recent anastomosis. Segmental resection was performed.     

An unusual abdominal mass in an elderly patient.

Adult intussusception is rare and is often not included in the differential diagnosis. Patients who have previously undergone some form of gastric bypass procedure are more susceptible. We report a case of retrograde intussusception following a Roux-en-Y gastric bypass in an elderly patient, who presented with an abdominal mass. Her initial provisional diagnosis was bowel obstruction. As the number of bariatric gastric bypass procedures continues to rise, we are likely to see more of this kind of post-operative complication. Hence, it is crucial for surgeons to consider intussusception as a cause of abdominal pain, obstruction or mass in patients who have undergone some form of gastric bypass procedure.
