Intussusception of the Meckel’s diverticulum within its own lumen: Unknown complication

IntroductionIntussusception with the Meckel’s diverticulum (MD) is a rare cause of chonic abdominal pain in the adults. We wish to present this first case of intussusception of MD within its own lumen without small bowel obstruction.Presentation of caseWe report the case of a 27-year-old man who was admitted to the emergency room due to a diffuse abdominal pain. Abdominal CT scan showed invagination of MD. The exploratory laparoscopy revealed the presence of intussusception of MD within its own lumen. Segmental resection of the small intestine was performed. The patient was discharged on the third post-operative day.DiscussionThe prevalence of MD is 1 to 4%. Diagnosis is often difficult and delayed because clinical symptoms are not specific and the diagnosis is performed mainly by imaging studies. Factors pre-disposing these patients to intussusception of MD within its own lumen include a narrow diverticulum, large diverticululm, and associated inflammation of the diverticulum. Intestinal obstruction is a more common complication in adults, whereas in children, bleeding is the more common complication. In our case, the patient had a diffuse abdominal pain without small bowel obstruction because the intussusception of MD was within its own lumen. Laparoscopy may be useful for confirming the presence of intussusception, and demonstrating the underlying organic lesion serving as the lead point.ConclusionIt is important to differentiate this rare pathological feature of MD from other entities as the treatment is surgical rather than medical. Abdominal surgeons should bear in mind this rare entity.     

Small bowel intussusception with the Meckel's diverticulum after blunt abdominal trauma: a case report

Intussusception with the Meckel's diverticulum is a rare but well-known cause of small bowel obstruction in the adult. After blunt abdominal trauma, intussusception is exceedingly rare and has been reported previously only in few cases. We present a case of a previously healthy 28-year-old man developing four days after blunt abdominal trauma signs of small bowel obstruction. Ileo-ileal intussusception was suggested by computed tomography. Exploration revealed ileo-ileal intussusception with Meckel's diverticulum. A diverticulectomy with small bowel resection was performed.     

Meckel's diverticulectomy: a multi-centre 19-year retrospective study

Background

Meckels diverticulum (MD) causes a number of acute surgical pathologies and can contain ectopic tissue with the surgical aim to resect all ectopic mucosa. This has traditionally implied a small bowel resection (BR); though contemporary literature has demonstrated Meckel's diverticulectomy to be safe. The aim of this study was to determine optimal resection strategy, and assess MD histopathological features and their relationship to outcomes.

Methods

A 19-year retrospective review of patient medical records across seven hospitals was conducted with demographic, clinical and pathological data collected. Analysis was conducted using a student's t-test for continuous variables and chi-squared test for categorical variables. Univariate regression was performed to identify risk factors. P < 0.05 was considered statistically significant.

Results

One hundred and sixty patients underwent resection of MD, 70 (44%) had Meckel's diverticulectomy and 90 (56%) had BR. No significant difference in length (P = 0.486), width (P = 0.238), or ratio (P = 0.188) of diverticulectomy compared to BR, with fewer complications in diverticulectomy. In all, 24 (15.3%) MD were perforated, of whom 5 had gastric mucosa, 2 had mixed ectopic mucosa and 1 carcinoid tissue. There were no cases of ectopic mucosa in the resection margin requiring re-operation, or causing base perforation. MD specimen with greater length: width ratio was a risk factor for perforation OR 1.437 P = 0.042 but not for malignancy P = 0.813 or ectopic tissue P = 0.185.

Conclusion

Meckel's diverticulectomy is safe via laparoscopic or open approach compared with BR. Despite higher perforation rates in MD with greater length: width ratio, no malignancy or ectopic risk was identified, supporting diverticulectomy as a safe operative approach.     

Community teaching hospital surgical experience with adult intussusception: Study of nine cases and literature review

IntroductionAlthough more commonly thought of as a surgical problem affecting children, surgeons evaluating the adult acute abdomen should remain vigilante in diagnosing intussusception. In this case series, we reviewed 6 years of medical records at a community teaching hospital in order to analyze the etiology, presentation, and management of nine cases of adult intussusception.Presentation of casesMost of the patients in our series shared symptoms of nausea, vomiting, and abdominal pain. Computed tomography scan was crucial in distinguishing adult intussusception from other causes of acute abdomen. Eight patients underwent operative exploration, five of whom underwent bowel resection. One patient’s symptoms resolved with no surgical intervention. All nine patients had excellent outcomes.DiscussionAlthough detailed history and physical examination are essential in all cases of acute abdomen, CT scan findings of “target” signs are pathognomonic of intussusception. Laparoscopy should be strongly considered in select cases. Current literature suggests that reduction may be performed before resection if the lesion meets certain stringent parameters. The primary concern with regards to reduction before resection is potential embolization of malignant cells. Colonic intussusception is almost always treated with resection without reduction, while small intestinal intussusception could be treated by reduction before resection, if the small bowel lead points are less likely to be malignant.ConclusionIntussusception is a rare but serious etiology of the acute abdomen in adults. Each case should be evaluated independently according to the specific type of lead-point lesion. Excellent outcomes may be anticipated with prompt diagnosis and surgical treatment.     

Current success in the treatment of intussusception in children

BACKGROUND: Intussusception remains a common cause of bowel obstruction in young children and results in significant morbidity and mortality if not promptly treated. The goal of this study was to determine the current success rate of radiologic reduction, the requirements for operative intervention, and the effect of delay in presentation on outcome. METHODS: Children treated for intussusception over a 15-year period were reviewed after treatment at a tertiary children's hospital. Records were reviewed for patient outcomes from radiologic evaluation and surgical intervention. RESULTS: Two hundred forty-four children with intussusception were identified. Median age was 8.2 months (range, 16 days to 12.7 years). Eighty-seven percent of patients had ileocolic or ileoileocolic intussusception. The most common presenting symptoms were emesis (81%), hematochezia (61%), and abdominal pain (59%). Contrasted enemas were performed in 190 children, with successful reduction in 46%. Air-contrasted enema reduction was more successful than liquid-contrasted techniques (54% vs 34%; P = .017). Success in reduction was greater if symptom duration was <24 hours compared with >24 hours (59% vs 36%; P = .001). Despite failed prior attempts at reduction, 48% were reduced on reattempted enema reduction. One hundred forty children required surgical intervention for intussusception with 50% requiring bowel resection. Children with symptom duration >24 hours had a greater risk of requiring surgery (73% vs 45%; P < .001) and bowel resection (39% vs 17%; P = .001) than those with symptoms for <24 hours. Pathologic lead points were encountered in 14%. There were 2 deaths and complications occurred in 19%. Length of stay after surgical reduction was 3.9 days, but 6.1 days if bowel resection was required. CONCLUSIONS: Success of intussusception reduction is improved with air-contrasted techniques and is not affected by previously failed, outside attempts. Delay in presentation decreases success in radiologic reduction and increases risk of operative intervention and bowel resection.     

Ileocecal intussusception in an adult: the laparoscopic approach.

Adult intussusception is uncommon and requires a surgical approach. Malignancy is associated with 31% (43/137) of small bowel intussusception and 70% (74/106) of large bowel intussusception. Computerized tomography (CT) findings are pathognomonic for this condition. Often, the patient presents with long-standing, nonspecific complaints. A 63-year-old man presented with sudden onset of abdominal pain. CT demonstrated colonic inflammation. A laparoscopic right hemicolectomy for ileocecal intussusception was performed. The pathology report revealed a lipoma of the cecum. The postoperative course was uneventful, and he was discharged the fifth postoperative day. Despite a high incidence of malignancy, colonic or ileocecal intussusception can be successfully treated by laparoscopic resection. Review of the literature and treatment options are discussed.     

National trends in the surgical management of Meckel's diverticulum

Background

Treatment recommendations for Meckel's diverticulum (MD) come mostly from single-institution case series. The objective of this study was to review the surgical management and outcomes of children undergoing Meckel's diverticulectomy using contemporary data from a national database.

Methods

We queried 2007 to 2008 data from the Pediatric Health Information System database and analyzed demographic and outcome variables for patients undergoing surgical resection of MD. Cases were classified as primary (symptomatic MD) or secondary (incidental MD). Outcomes in primary cases were compared between open and laparoscopic approaches. Statistical analyses were performed using SPSS (Chicago, IL).

Results

Eight hundred fifteen children underwent Meckel's diverticulectomy. Meckel's diverticulectomy was more common in boys (boy-girl, 2.3:1), and half (53%) of the children required surgery before their fourth birthday. More cases (n = 485; 60%) were classified as primary, and most children were approached by laparotomy (75%). The most common presentations for primary cases were obstruction (30%), bleeding (27%), and intussusception (19%). In the primary group, patients treated with the laparoscopic approach had a shorter length of stay (open approach, 5.7 ± 5.2 days; laparoscopic approach, 4.3 ± 2.7 days; P < .02).

Conclusion

These data describe current trends in the surgical treatment of MD in the United States. Laparoscopic Meckel's diverticulectomy appears to shorten length of stay but is used much less frequently than the traditional open approach.     

A case of postoperative recurrent intussusception associated with indwelling bowel tube

Intussusception is quite uncommon in adults. We report a rare case of a 76-year-old man with small bowel intussusception induced by two indwelling bowel tubes, the first a jejunal feeding tube and the second an ileus tube. After complete reduction of the first intussusception caused by the jejunal feeding tube and adhesion, re-intussusception occurred due to the postoperative adhesion and ileus tube inserted into the bowel after the previous operation for intussusception. Finally, the part of the jejunum with re-intussusception and adhesion, including the place where the previous reduced intussusception had occurred, was resected. This case is a reminder that when there is no mucosal lesion other than an indwelling bowel tube or a hard adhesion/inflammation around intussusception, the patient should be operated on without delay for resection of the intussusception to prevent re-intussusception, even if the resected bowel is predicted to be long.     

Intussusception: An Uncommon Cause of Postoperative Small Bowel Obstruction after Gastric Bypass

Intussusception of the jejuno-jejunal anastomosis is a rare complication of the Roux-en-Y gastric bypass (RYGBP).There are only 3 previous cases reported in the surgical literature. We describe 2 adults who developed jejuno-jejunal intussusception requiring emergent laparotomy several months after RYGBP. Both patients underwent exploratory laparotomy after the diagnosis was made with abdominal CT scan. Each patient had an uneventful postoperative course after bowel resection and revision of the enteroenterostomy. Small bowel obstruction due to intussusception may occur many months after RYGBP and may present with non-specific symptoms such as crampy abdominal pain, nausea, and vomiting. The diagnosis of this rare entity is typically made via abdominal CT scan. Treatment mandates urgent abdominal exploration with reduction.     

Laparoscopic surgery for small-bowel obstruction caused by Meckel's diverticulum

A 26-year-old woman was referred to our hospital because of abdominal distention and vomiting. Contrastenhanced computed tomography showed a blind loop of the bowel extending to near the uterus and a fibrotic band connecting the mesentery to the top of the bowel,suggestive of Meckel's diverticulum(MD) and a mesodiverticular band(MDB). After intestinal decompression,elective laparoscopic surgery was carried out. Using three 5-mm ports,MD was dissected from the surrounding adhesion and MDB was divided intracorporeally. And subsequent Meckel's diverticulectomy was performed. The presence of heterotopic gastric mucosa was confirmed histologically. The patient had an uneventful postoperative course and was discharged 5 d after the operation. She has remained healthy and symptom-free during 4 years of follow-up. This was considered to be an unusual case of preoperatively diagnosed and laparoscopically treated small-bowel obstruction due to MD in a young adult woman.     

Intestinal intussusception as a complication of typhoid fever

Typhoid fever is a severe febrile illness caused by Salmonella typhi. Although ileal perforation and bleeding are seen more frequently, intestinal intussusception is a very rare complication of typhoid fever. A male patient was admitted to hospital due to abdominal distension and pain. Abdominal computerised tomography revealed ileal intussusception. The patient underwent exploratory laparotomy. Ileal intussusception was determined and segmental ileal resection was performed. Examination of the resected ileal segment revealed multiple ulcerous lesions that led to intussusception. The postoperative course was uneventful. The operative treatment is the subject of debate because of insufficient evidence. We recommend segmental bowel resection because of the underlying pathology.     

Gallstone ileus associated with impaction at Meckel&rsquo;s diverticulum: Case report and literature review

Gallstone ileus due to erosion of one or more gallstones into the gastrointestinal tract is an uncommon cause of small bowel obstruction. The site of impaction is usually distal ileum, and less commonly the jejunum, colon, duodenum, or stomach. We report a rare case of gallstone ileus with impaction at the proximal small bowel and at a Meckel’s diverticulum (MD) in a 64-year-old woman managed with laparoscopic converted to open small bowel resections. Patient was discharged home in stable condition and remained asymptomatic at 6-mo follow up. We review the current literature on surgical approaches to MD and gallstone ileus. Diverticulectomy or segmental resection is preferred for complicated MD. For gallstone ileus, simple enterolithotomy or segmental resection are the most the most favored especially in older co-morbid patients due to lower mortality rates and the rarity of recurrent gallstone ileus. In addition, laparoscopy has been increasingly reported as a safe approach to manage gallstone ileus.     

Adult intussusception secondary to inflammatory polyps

Adult intussusception is a rare entity that may present in the acute and subacute setting principally related to the degree of bowel obstruction. Preoperative diagnosis of this condition may be difficult. The intussusception is usually due to a definable intraluminal lesion, most probably neoplasia, unlike intussusception in children. We present the cases of two adult male patients with intussusception. The first presented with acute small-bowel obstruction secondary to a retrograde ileojejunal intussusception with a pseudopolyp as the lead point. This was possibly due to a retrograde ball-valve effect. The intussuscepting segment was resected. The second patient presented with unexplained chronic diarrhoea and an intussusception occurring within the caecum, as demonstrated at colonoscopy, with a terminal ileal pedunculated fibroid polyp as the lead point. A limited right hemicolectomy was performed. Both patients recovered uneventfully and have remained well. A brief literature review of adult intussusception complements the case reports, with an emphasis on the pathogenesis of inflammatory polyps and recommended surgical management.     

Intestinal Intussusception as a Complication of Typhoid Fever

Typhoid fever is a severe febrile illness caused by Salmonella typhi. Although ileal perforation and bleeding are seen more frequently, intestinal intussusception is a very rare complication of typhoid fever.

A male patient was admitted to hospital due to abdominal distension and pain. Abdominal computerised tomography revealed ileal intussusception. The patient underwent exploratory laparotomy. Ileal intussusception was determined and segmental ileal resection was performed. Examination of the resected ileal segment revealed multiple ulcerous lesions that led to intussusception. The postoperative course was uneventful. The operative treatment is the subject of debate because of insufficient evidence. We recommend segmental bowel resection because of the underlying pathology.     

Gallstone ileus associated with impaction at Meckel's diverticulum:Case report and literature review

Gallstone ileus due to erosion of one or more gallstones into the gastrointestinal tract is an uncommon cause of small bowel obstruction. The site of impaction is usually distal ileum, and less commonly the jejunum, colon, duodenum, or stomach. We report a rare case of gallstone ileus with impaction at the proximal small bowel and at a Meckel's diverticulum(MD) in a 64-yearold woman managed with laparoscopic converted to open small bowel resections. Patient was discharged home in stable condition and remained asymptomatic at 6-mo follow up. We review the current literature on surgical approaches to MD and gallstone ileus. Diverticulectomy or segmental resection is preferred for complicated MD. For gallstone ileus, simple enterolithotomy or segmental resection are the most the most favored especially in older co-morbid patients due to lower mortality rates and the rarity of recurrent gallstone ileus. In addition, laparoscopy has been increasingly reported as a safe approach to manage gallstone ileus.     

Jejuno-jejunal intussusception in a post-lung transplant patient from a gastrojejunostomy tube: A case report

Introduction: Gastro-jejunostomy tube is used for post-pyloric feeding for critical-ill patient who cannot tolerate oral alimentation. Jejuno-jejunal intussusception is a rare complication of gastrojejunostomy tube.Presentation of case: A 39-year-old male with history of severe combined immunodeficiency, Achalasia and end-stage lung disease underwent double lung transplantation. After lung transplantation, he required gastrojejunostomy(GJ) tube placement due to his esophageal disease. Four days after gastrojejunostomy tube placement, he developed jejuno-jejunal intussusception. A 15 cm segment of thickened and enlarged bowel, which consisted of the intussusception were identified laparoscopically. Surgical reduction was performed without bowel resection.Discussion: Intussusception is uncommon in adults compared to pediatric population. In this rare case, the jejunal limb of the GJ tube placed in jejunum was the cause of jejunojejunal intussusception serving as the lead point. The GJ tube should not be placed farther down from ligaments of Treiz to prevent jejuno-jejunal intussusception.Conclusions: A heightened index of suspicion for this rare complication should exist with a presenting patient has signs of proximal bowel obstruction and CT evidence of intussusception.     

Three cases of small bowel intussusception in relation to a rare lesion: inflammatory fibrous polyps

BACKGROUND/AIMS: Inflammatory fibrous polyps (IFPs), also known as inflammatory pseudotumors, occur rarely in the gastrointestinal tract. IFPs have variable presentations, often presenting as small bowel obstruction due to intussusception or, less commonly, as an incidental finding on radiological examinations or screening colonoscopies. The diagnosis and management of IFPs will be discussed through a review of the literature and a series of cases from our own institution. METHODS: A retrospective analysis of the diagnosis, management and complications of IFPs was performed by a literature review. This was accompanied by a series of 3 cases of IFPs, 2 of which causing intussusception, diagnosed and treated in our own institution. CONCLUSIONS: IFP is a rare disease and has a variable presentation, from asymptomatic to small bowel obstruction due to intussusception. IFPs cannot be differentiated from malignancy without histological examination. Therefore, whether diagnosed incidentally or in the setting of intussusception, the treatment of IFPs is surgical resection of the involved bowel.     

Intussusception in children 5-15 years of age

Twenty cases of intussusception in children between the ages of 5 and 15 years were compared with intussusception in infancy and early childhood. They accounted for 18.5 per cent of all 108 children treated for intussusception in two large hospitals from 1964 to 1984. Diagnosis of intussusception was delayed, probably due to an unusual presentation. Fifty-five per cent had a definite predisposing factor precipitating the intussusception and 45 per cent had a small bowel intussusception, which warranted early surgical intervention. In the absence of contraindications no child should be disqualified from an attempt at hydrostatic reduction. After hydrostatic reduction careful follow-up is required to exclude an organic lesion, possibly by a small bowel follow-through meal. Surgery is indicated after hydrostatic reduction in case of chronically recurrent abdominal complaints.     

Controversy in the treatment of adult long ileocolic intussusception: case report

Adult intussusception is an unusual cause of intestinal obstruction. In contrast to children, intussusception in adults is usually due to an identifiable cause. We present a case of an 81-year-old female who was diagnosed with a long intussusception on CT scan of the abdomen. Because of the likelihood of neoplasia, a right hemicolectomy was undertaken, after which the patient recovered well. The correct treatment of adult intussusception is not unanimously agreed upon. We present a case of long intussusception in which partial reduction of viable small bowel before the resection was done by applying gentle traction. This provided sufficient small bowel mesentery length, preventing any damage to superior mesenteric vessels and avoiding unnecessary excision of healthy bowel.     

Peutz-Jeghers syndrome in a woman presenting as intussusception: A case report

IntroductionPeutz-Jeghers syndrome (PJS) is an uncommon autosomal dominant syndrome with a variable to high penetrance that leads to the development of polyps within the gastrointestinal mucosa. Here we report a case of an adult female suffering jejunoileal intussusception due to PJS.Presentation of caseA 30-year-old woman came to an emergency department with a small bowel obstruction caused by intussusception. The patient underwent an emergency exploratory laparotomy. An intussusception at the level of 60 cm from the ligamentum treitz was revealed, and the intussusception small bowel segment was not viable; we decided to perform segmental jejunoileal resection with the Bishop-Koop procedure, and the specimen histopathology of the segmental jejunoileal resection showed a typical hamartomatous polyp features. Two month later, diagnostic endoscopy showed multiple polyps (between 5 and 15 mm) in the large bowel. The polyps were removed with endoscopic polypectomy and examined histopathologically, showing characteristics of PJS. Further detailed family history was obtained, and similar skin lesions were detected on our patient’s child (since birth). Although endoscopy screening identified multiple polyps in the child’s ileum and large bowel, he was not suffering from abdominal symptoms.ConclusionIn patients with intussusception at a young age, PJS can be caused by the presence of a hamartoma polyp as a trigger for intussusception. If there are multiple polyps found in the gastrointestinal mucosa and other pathognomonic signs are found, such as hyperdense macular lesions on the lip and buccal mucosa, such cases should be confirmed as PJS.
