Ileal lipoma - a rare cause of ileocolic intussusception in adults: Case report and literature review

The occurrence of intussusception in adults is rare,accounting for less than 5% of all cases of intussusceptions and almost 1%-5% of bowel obstruction.The condition is found in less than 1 in 1300 abdominal operations and 1 in 100 patients operated for intestinal obstruction.The child to adult ratio is more than 20:1.We report a rare case of ileocolic intussusception in an adult secondary to an ileal lipoma.     

Laparoscopic resolution of intussusception after Roux-en-Y gastric bypass

Introduction

Roux-en-Y gastric bypass (RYGB) has been the most common surgical operation used to treat obesity and its inherent co-morbidities. Intussusception with bowel obstruction after RYGB is a rare complication and its physiopathology remains unclear. The diagnosis is generally based on typical image of computed tomography (CT) scan and a surgical exploration is generally recommended.

Clinical outcomes following bowel resection versus reduction of intussusception

Background

Intussusception is most commonly managed with air-contrast reduction. However, when this fails, emergent operation with resection or manual reduction is indicated. It is not known if there are advantages to resection compared with manual reduction.

Methods

A retrospective review of all patients receiving operative care for intussusception from February 2000 to December 2011. Patients undergoing intestinal resection were compared with those treated with manual reduction alone.

Results

Of 111 patients, 49 underwent resection and 62 underwent manual reduction. Mean (±SD) time to oral intake favored manual reduction (2.1 ± 1.2 versus 2.6 ± 1.2 d, respectively, P = 0.05). Manual reduction was associated with a greater need for repeat imaging (47% versus 18%, P = 0.002) and the only recurrences were with manual reduction (8% versus 0%, P = 0.1). Mean duration of stay was no different (P = 0.36), nor was the need for reoperation (P = 0.9).

Conclusions

Patients undergoing manual reduction have an increased number of radiographic imaging procedures. The surgeon should have a low threshold for resection for intussusceptions requiring operative management.     

Small bowel intussusception with pelvic plastron secondary to acute appendicitis in child

We report an unusual case of a 3-year-old child with appendicitis complicated by ileoileal intussusception. Although acute complicated appendicitis and concurrent ileoileal intussusception represent a possible cause of an acute abdomen, very few cases have been reported in the literature.     

Ileocolic intussusception due to endometriosis.

Intussusception is a rare cause of bowel obstruction in adults. Clinical manifestations are not specific, making the preoperative diagnosis difficult to establish. We report a case of acute small-bowel obstruction due to ileocolic intussusception. An emergency explorative laparoscopy was performed and revealed a mass in the right colon proximal to the ileocecal valve. Conversion to open laparotomy allowed us to perform a right hemicolectomy. The pathologic examination of the resected sample revealed endometriosis of the terminal ileus.

Small bowel intussusception in celiac disease

Intussusception is not a widely recognized complication of celiac disease and yet it is not rare. The authors report on 3 children with spontaneously resolving small bowel intussusception in association with celiac disease. Small bowel intussusception in a child with suspected celiac disease initially should be managed expectantly rather than by early surgical reduction. The finding of transient small bowel intussusception, either by contrast radiology or sonography, should prompt investigation for celiac disease.     

Small bowel intussusception after blunt abdominal trauma in a 6-year-old boy: case report and review of 6 cases reported in the literature

Although intussusception is a well-known cause of acute abdomen in the pediatric population, traumatic intussusception is exceedingly rare and has been reported previously only 6 times in a preadolescent child. We present a case of ileoileal intussusception in a previously healthy 6-year-old boy after blunt trauma to the abdomen and review the English language literature on the subject.     

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.     

急性肠梗阻的螺旋CT诊断

Glucagon in experimental intussusception

A standard type of ileocolic intussusception was produced in 69 puppies and the effect of glucagon on the hydrostatic reduction of the intussusceptions evaluated in a prospective, double-blind study. The reductions were attempted at intervals varying from 18 to 60 hr following the production of the intussusceptions. The overall reduction rate was 70% and there was no statistical difference in this rate between the animals receiving glucagon and those receiving placebos. None of the gangrenous intussusceptions were reducible with the hydrostatic pressure technique, irrespective of whether glucagon was used or not. A further evaluation was made of those animals in whom successful reductions were accomplished by the hydrostatic pressure method. Glucagon did result in significantly easier reductions, and an earlier return of normal vascular supply as measured by color and by arterial pulsations as compared to the control group.     

Small bowel tumours causing intussusception in childhood

In a series of 292 children with intussusception ten (3.5 per cent) were caused by small bowel tumours. The average age of these patients was greater than in idiopathic cases; seven of the ten being older than 2 years. Intussusception due to Peutz-Jeghers hamartomas was jejunojejunal whereas other small bowel tumours causing intussusception were in the terminal ileum. The majority of these intussusceptions were either irreducible or gangrenous and all required resection of bowel. There was only one death in the entire series of 292 patients, and this was a child with lymphosarcoma.     

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.

Preoperative evaluation by magnetic resonance imaging in patients with bowel obstruction

BACKGROUND: Bowel obstruction is a problematic condition because the main clinical issue is to determine whether emergency laparotomy or observation with a long tube is required. The recent development of imaging diagnostic modalities such as magnetic resonance imaging (MRI) is thought to be promising to support therapeutic decisions in patients with bowel obstruction. METHODS: Twenty-seven patients with bowel obstruction who underwent laparotomy were evaluated by plain x-ray film, computed tomography (CT) scan, and MRI preoperatively with regard to the presence or absence of bowel obstruction, and the site and cause of bowel obstruction. Diagnostic accuracies were compared among these radiological modalities. RESULTS: The presence of bowel obstruction was detected in 22 (81.5%) of 27 patients by plain abdominal x-ray film, in 24 (92.3%) of 26 patients by CT scan, and in 25 (92.6%) of 27 patients by MRI. The sites of obstruction were consistent with surgical findings in 25 (92.6%) of 27 patients by MRI, and in 15 (57.7%) of 26 patients by CT scan. The causes of bowel obstruction were accurately diagnosed by MRI in 25 (92.6%) of 27 patients, and in 23 (88.5%) of 26 patients by CT scan. CONCLUSIONS: MRI could identify the presence and the site and cause of bowel obstruction in most of the cases. MRI is assumed to be superior to CT scan in the preoperative diagnosis of bowel obstruction.     

Intussusception After Laparoscopic Roux-en-Y Gastric Bypass

Intussusception after open Roux-en-Y gastric bypass procedure (RYGBP) is a rare complication. We present a retrospective review of three cases of antegrade intussusception occurring after laparoscopic RYGBP. To our knowledge, these are the first documented cases of intussusception after laparoscopic RYGBP. We describe the clinical presentation and our management of these three cases. Furthermore, we believe that the initial clinical presentation, radiographic findings, and management of these patients may be different than those patients who have undergone an open RYGBP. With increasing popularity of laparoscopic RYGBP, we are likely to see more of this entity.     

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.
