Adult colonic intussusception

Objective: To study the clinical characteristics, investigations, management and pathology in adult colonic intussusception. Methods: A retrospective study of seven adult patients who were operated on for the diagnosis of colonic intussusception in our department from January 1999 to September 2003 was carried out. The case records of the seven patients were retrieved. Their clinical presentations, investigations, operative records and pathology were studied. Results: The mean age of the patients was 67.4 years. There were four men and three women. Five of the patients presented with chronic non‐specific symptoms and the other two patients presented with acute symptoms. Transabdominal ultrasonography (USG) and computed tomography (CT) scan were used for investigation. In the majority of the patients (87.5%), radiological features of intussusception were shown by USG or CT scan. All seven patients underwent laparotomy exploration with bowel resection. Six patients (85.7%) had lead points with definable pathology. Within the lead points, five patients had primary malignant lesions. Conclusion: With more liberal use of imaging techniques, more adult intussusception can be diagnosed before explorative surgery. Ultrasound would be an ideal tool for initial evaluation. In view of the high chance of associated malignancy, adult colonic intussusception should be resected without prior reduction at the time of surgery.     

Adult intussusception: A 15‐year retrospective review

Objective: Adult intussusception is an uncommon disease and is usually associated with malignancy. In many cases, diagnosis is made only in the theatre as a result of its non‐specific presentation and low index of suspicion. By reporting the present study, we would like to share our experience in managing this condition. Methodology: Patients with the diagnosis of intussusception admitted to Queen Elizabeth Hospital within the period 1996–2010 were included. Demographic data, presenting symptoms, and operative and pathological findings were collected and analysed. Results: There were 37 adult intussusceptions in the study period; 18 of them were female and 19 of them were male. The mean age of the patients was 67 years. More than 40% of the patients had subacute onset of the symptoms. Abdominal pain was the most common presenting symptom, present in 83.5% of the patients. Preoperative diagnosis was made in 62.2% of the cases and all of these received either preoperative computed tomography and/or ultrasonography. There were nine enteric and 28 colonic intussusceptions. A pathological lead‐point could be identified in 83.8%, and their size ranged from 2 cm to 8 cm. The malignant lead‐point was larger than the benign one lead‐point (4.74 vs 3.3, P = 0.021). Malignancy was found in 33.3% of the enteric lesions and 60.7% of the colonic lesions. respectively. Age older than 70 years was found to be an associated risk factor for malignancy (P = 0.022). Conclusion: Intussusception should be considered as one of the differential diagnoses, especially in elderly patients complaining of subacute abdominal pain. Computed tomography scan should be the imaging of choice. Oncological resection should be carried out without attempt of reduction if the patient is older than 70 years, having colonic intussusception and containing a large lead‐point.     

Adult suprapatellar pleiomorphic rhabdomyosarcoma with jejunal metastasis causing intussusception: a case report

Jejuno-jejunal intussusception is rarely encountered in adults. Management depends on the viability of the involved bowel. Exploration is favored because in adults generally an underlying ‘lead point’ is found to be present. Pleimorphic rhabdomyosarcoma (pRMS) arises from striated muscle cells. They are usually diagnosed during childhood and can occur virtually all over the body, controversially in places were few striated cells are found. In adults, these tumors are rare and are mostly encountered in the head-and-neck region. We present the case of a 48-year-old woman with a jejunal metastasis from a suprapatellar pRMS diagnosed 2.5 years earlier resulting in a jejuno-jejunal intussusception.     

A special type of postoperative intussusception: ileoileal intussusception after surgical reduction of ileocolic intussusception in infants and children

Background

Postoperative ileoileal intussusception after surgical reduction of ileocolic intussusception in infants and children is extremely rare, and no reports of this special type of postoperative small bowel intussusception have been found in the literature.

Methods

We retrospectively reviewed the clinical charts of 6 infants and children with postoperative ileoileal intussusception that occurred after surgical reduction of ileocolic intussusception between January 1994 and December 2006. Clinical features, diagnostic strategy, operative findings, and outcome were analyzed.

Results

All 6 cases of postoperative ileoileal intussusception after surgery for ileocolic intussusception occurred within 1 week after the initial operation. The clinical manifestation was intestinal obstruction without abdominal palpable mass or bloody stool. Abdominal ultrasound examination revealed the target sign in 5 cases. Manual reduction of the intussusception was performed successfully at reoperation in each instance.

Conclusions

The clinical symptoms of postoperative ileoileal intussusception after operations for ileocolic intussusception are not typical. A second postoperative (ileoileal) intussusception should be kept in mind after surgical reduction of the first (ileocolic) intussusception in children. In any atypical postoperative ileus, a sonographic study should be done to rule out the diagnosis of postoperative intussusception. Once this condition is diagnosed, surgical treatment should be performed as soon as possible.     

Post operative recurrent acute jejuno-jejunal intussusception

A case of recurrent acute jejuno-jejunal intussusception presenting in the post operative period of the surgery for acute ileocolic intussusception is presented. Post operative intussusception is defined as intussusception occurring within 30 days of the primary surgery [1]. This is a rare entity. Jejuno-jejunal intussusception is also rare. Recurrent intussusception is uncommon. The present case is a combination of all these rarities.     

Compound colonic intussusception: a reason for failure of pneumatic reduction

Intussusception is the most common cause of bowel obstruction in infants older than 3 months. The authors report a case of idiopathic compound (ileocolic/colocolic) intussusception in a 5-month-old girl that was resistant to nonsurgical pneumatic (enema) reduction and necessitated open surgery. Compound intussusception is extremely rare but represents a form of intussusception that is likely to be aggravated by attempts at pneumatic reduction with obvious dangers for the unwary. The literature is reviewed, and the terminology was discussed.     

Postoperative retrograde intussusception in an infant: a rare occurrence

Retrograde intussusception is a rare postoperative complication, most commonly after gastric resection or gastrojejunostomy. This report describes a case of retrograde jejunojejunal intussusception after duodenal atresia repair.     

Adult intussusception with cecal adenocarcinoma: Successful treatment by laparoscopy-assisted surgery following preoperative reduction

We report a case of adult intussusception caused by cecal adenocarcinoma that was treated by laparoscopyassisted ileocecal resection following reduction by contrast enema and preoperative colonoscopy.A 68-yearold male with cecal cancer was admitted to our hospital because of colicky abdominal pain after taking a laxative.His abdomen was distended,and a mass was palpable in the right upper quadrant,which appeared as a target-or sausage-shaped lesion by ultrasonograhpy and computed tomography.A contrast enema using water-soluble material showed a cup-shaped filling defect characterized by intussusception in the ascending colon.This round defect with a clear margin was pushed gradually back into the cecum by the enema pressure.Re-occurrence of the intussusception is easilyreleased by colonoscopy.We performed laparoscopyassisted ileocecal resection of a protruding tumor measuring 6.5 cm × 5.0 cm × 3.5 cm from the cecum,with D3 lymph node dissection.Histological examination revealed a well-differentiated adenocarcinoma that had invaded the serosa without permeating the lymphatic or venous capillaries,as well as lymph node metastasis.The postoperative course was uneventful,and the patient has been well without evidence of disease recurrence for 5 years following the operation.Preliminary reduction of adult colonic intussusception before surgical resection is therefore an option in cases of an early and correct diagnosis of intussusception.     

Endometriosis-induced appendiceal intussusception

Appendiceal intussusception is a rare entity that is difficult to diagnosis before surgery both clinically and radiologically. We report here a case of a 55-year-old woman with a 6-month history of right lower abdominal pain caused by appendiceal intussusception. Laparoscopic appendectomy was performed. Endometriosis foci were identified in the appendix tip and became the leading point of the appendiceal intussusception. The appendix was removed laparoscopically, which is the optimal treatment for such patients.     

Profiling adult intussusception patients: comparing colonic versus enteric intussusception

Background

Adult intussusception is a rare entity representing 1% of all adult bowel obstruction, hospital admissions secondary to intussusception historically has ranged between .003% and .02%. There is limited knowledge regarding enteric and colonic surgical intussusception patients and their associated conditions.

Methods

A retrospective study was conducted using data from the National Inpatient Sample from 1998 to 2006. The inclusion criteria were surgical patients with intussusception.

Results

A total of 1,178 cases of intussusception requiring surgery were isolated from the database. The mean patient age was 49.57 years, about 58% were females, 99.43% of this population was insured, and the overall mortality rate was 1.70%. Colonic resection was associated with greater mortality compared with the enteric resection group (P = .018).

Conclusions

This was a large study on surgical adult intussusception patients conducted in the United States. We show differences in demography, comorbidities, and potential causes between colonic and enteric intussusception.     

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.     

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.     

The impact of hospital type and experience on the operative utilization in pediatric intussusception: a nationwide study

Purpose

To determine the impact in clinical outcomes of pediatric idiopathic intussusceptions from hospital experience and designation as children's hospitals (CH) and non-children's hospitals (NCH) in the US.

Methods

A retrospective study was performed on 1263 children with idiopathic intussusception, 2 months to 3 years of age in 2000 and 2003 by extracting data from the Healthcare Cost and Utilization Project Kid's Inpatient Database. Main outcome measures were utilizations of operation and radiologic reduction. Statistical significance was defined as P < .05.

Results

The median hospital volume of intussusceptions was higher at CH (2.5 vs 0.5 cases per year, P < .001) compared to NCH. Children treated at CH had lower risk of operation (55 vs 68%, P < .001) and higher likelihood of radiologic reduction (39 vs 26%, P < .001) compared to NCH. Multivariate regression analysis showed a 17% reduction of operative utilization at CH vs NCH. Outcomes were positively related to experience as high-volume hospitals reduced operative utilization by 19%. Rates of successful radiologic reduction were similar between hospital types, which was 85% nationally.

Conclusion

Children with intussusception have decreased likelihood of operation when treated at CH compared to NCH. This decreased operative utilization can be attributed to the increased experience and utilization of radiologic reduction at these specialty hospitals.     

Non-surgical treatment of jejunogastric intussusception

Summary Three cases of retrograde jejunogastric intussusception who were managed endoscopically are described. The diagnosis was made by means of endoscopy in one case and contrast radiology of the stomach in the other two. Endoscopic management consisted of reduction of the intussusception, followed by placement of a feeding tube deep in the intussuscepting segment. The patients responded very well and surgery could be avoided in all of them.
