Hydrostatic reduction of intussusception is definitive therapy in most infants with this abnormality. In the older child, adolescent, and adult, a polyp or tumor is often present. Operative intervention should be considered earlier in the clinical course both to relieve the intussusception and to define the nature of the lead point.
The hamartomatous polyps of Peutz-Jeghers Syndrome (PJS) can cause repeated episodes of rectal bleeding and intestinal subocclusion. Laparoscopic treatment of intussusception is rarely reported and must be considered for this clinical condition. We described a 35-year-old male with PJS who presented with rectal bleeding and abdominal pain. One duodenal polyp and two others in the jejunum, which caused intussusception, were visualized on preoperative investigation. Polyps were identified by laparoscopy and removed extracorporeally through enterotomies. All lesions were hamartomas. The patient was discharged on the third postoperative day and has been asymptomatic for more than 2 years. Laparoscopy allows an adequate access to explore and treat small bowel polyps and avoid the classic laparotomy.
Cutaneous angiosarcoma is a rare aggressive vascular tumor that occurs in elderly patients and is usually located on the head and face. Metastases often develop in the cervical lymph nodes, lungs, bone, liver and spleen. There have been no reports of ileoileal intussusception due to metastatic tumor from cutaneous angiosarcoma. We reported a case of cutaneous angiosarcoma in a 67-year-old Japanese male accompanied with ileoileal intussusception due to metastatic angiosarcoma. We assume that the metastatic tumor in the small intestine was metastasized hematogeneously from cutaneous angiosarcoma, resulting in the formation of nodules and the rapid growth of a pedunculated tumor as a forerunner of the ileoileal intessusception.
A recently dead adult female European brown hare (Lepus europaeus Pallas) was found in the wild with no evidence of trauma or external injury. Necropsy revealed symptoms consistent with endotoxic shock and a haemorrhagic jejuno-jejunal intussusception with a necrotic intussusceptum. Small, unattached nodules were present extensively in the jejunal lumen and within the intussuscipiens. These nodules proved to be masses of unsporulated Eimeria leporis oocysts. Review of the literature reveals E. leporis to be a common parasite of wild hares, with protracted pathogenic potential under some circumstances. This is the first report of intussusception in this species and the most severe lesion seen associated with E. leporis. This case suggests that E. leporis may be more harmful to the wild European brown hare population than previously supposed.
A case of jejunojejunal intussusception in a 59 year old male secondary to a leiomyoma is reported. The patient presented with abdominal pain and vomiting. He was admitted with a diagnosis of gastroenteritis. Antegrade barium study showed a jejunojejunal intussusception with a soft tissue mass as the lead point. Computed tomography scan demonstrated the soft tissue mass to have properties suggestive of a leiomyoma. The diagnosis was confirmed on examination of the excised specimen.
Intussusception in the adult is an uncommon cause of intestinal obstruction. Seventeen cases were seen at two teaching hospitals over a twenty-year period. A local causative lesion was present in all cases; a malignant tumour was present in two out of seven intussusceptions arising in the small intestine and in seven out of ten arising in the large intestine. More than half the cases had a protracted clinical course prior to diagnosis.
A case of ileocolic intussusception, associated with mid-gut volvulus and malrotation with bowel necrosis is reported. There is evidence to suggest that the intussusception preceded the volvulus.
A review was conducted of children with intussusception admitted to the Royal Children's Hospital over a 16 year period: of 630 episodes of intussusception, 28 represented recurrences (4.4%): 10 of these occurred in children aged 2 years or over. Duration of symptoms and the incidence of an incorrect initial diagnosis were markedly reduced with recurrence. The clinical presentation was similar to the first episode apart from rectal bleeding which was less common, reflecting the shorter history. Sixteen barium enemas were performed, of which 10 were successful. There were 18 operations with eight resections; seven for localized lesions and one for failure of manual reduction in a patient with an inverted Meckel's diverticulum. Barium reduction for recurrence should not be attempted in children over 2 years of age in whom no laparotomy was performed for their first episode, for most second recurrences, or in multiple polyposis.
Patients with intussusception who have necrotic bowel requiring bowel resection or who are at major risk of perforation from attempted hydrostatic reduction may be better managed without barium reduction. Ideally, the clinician would like to identify such patients at presentation. Two groups of patients, representing the extreme ends of the intussusception treatment spectrum were investigated in order to highlight the clinical features of patients in whom an attempted barium reduction is not justified. A group of 200 patients who had successful and safe hydrostatic reduction was compared with 104 patients who ultimately required bowel resection. Four features were found to be indicators of an increased likelihood of resection: age 3 months or less, or greater than 2 years, duration of symptoms greater than 24 h, presence of small bowel obstruction on plain radiology, and clinical assessment of dehydration greater than 5%. The validity of these features as prognostic indicators was assessed by applying them to all patients who had attempted barium reduction to see how they predicted patient outcome. In isolation, each feature was found to be compatible with a safe and successful hydrostatic reduction. The rate of resection was increased in patients with multiple adverse features and in these patients the enema technique may require modification. Patients with three or four adverse features had an unacceptably high incidence of gangrenous bowel requiring resection and a low likelihood of successful hydrostatic reduction. It is believed that attempts at reduction are not appropriate in these patients.
A case of malignant fibrous histiocytoma metastases to the small intestine and colon presenting as an intussusception is described. Although malignant fibrous histiocytoma is the most common soft tissue sarcoma in late adult life, GI involvement has rarely been reported. The review of both our case and eight cases in the English-language literature suggests that GI involvement from malignant fibrous histiocytoma occurs most frequently in the small intestine (six of nine) and that two major clinical manifestations of GI involvement are GI bleeding (five of nine) from ulcerated tumors and intussusception (two of nine) led by polypoid tumors.
OBJECTIVES: Rectal intussusception (RI) is a significant cause of morbidity amongst those with a rectal evacuatory disorder. The pathophysiology is unknown, but may involve abnormal biomechanics of the rectal wall similar to that previously demonstrated in patients with overt rectal prolapse (RP). Using an electromechanical barostat, this study aimed to investigate the biomechanics and visceroperception of the rectal wall in patients with RI. METHODS: Twenty consecutive patients (12 females, median age 46 yr (range 24-66)) with symptomatic, full-thickness RI were studied. Patients underwent assessment of rectal compliance, visceroperception, adaptive response to isobaric distension at urge threshold, and assessment of the postprandial response. Results were compared with those obtained in 28 asymptomatic volunteers, 10 with RI (6 females, median age 29 yr (range 21-36)) and 18 (9 females, median age 33 yr (range 21-62)) without. RESULTS: In the absence of the clinical finding of solitary rectal ulcer syndrome (SRUS), patients with symptomatic RI have normal rectal wall biomechanics, as do asymptomatic volunteers with RI (p < 0.05). Patients with the clinical finding of SRUS had reduced compliance and adaptation. In all three groups, there was a linear relationship between rectal pressure and visceroperception. The postprandial contractile response was similar between groups. CONCLUSIONS: Patients with RI have normal rectal wall biomechanics. This is in contrast to patients with RP, and suggests that while they may represent different stages of the same disease process, they are physiologically distinct. In patients with RI and SRUS, rectal wall inflammation and fibrosis, perhaps arising secondary to the intussusception, may explain the physiological changes observed.
Intussusception associated with Yersinia pseudotuberculosis infection was developed in three boys; two of them had a history of drinking untreated water. All intussusceptions were localized at the ileocolic region, and all patients completely recovered with Gastrografin enema and supportive treatment without complication and operation.
The aim of this study was to determine whether using air enema for acute intussusception is related to a higher rate of recurrence than other methods of treatment. A 10-y (1986-95) retrospective study was performed in a university-affiliated paediatric division. The overall recurrence rate for 97 patients with acute intussusception was 7.8% (10% of whom were treated non-surgically). There were no recurrences following the surgical treatment. In matched groups of patients, no risk factors were found for recurrence following air vs barium enema.
A 7-year-old female Maltese presented for evaluation of severe vomiting. A diagnosis of pylorogastric intussusception was made during ultrasonographic examination. The intussusception spontaneously underwent reduction by the following morning.
During a 14 year period, 27 of 310 horses undergoing laparotomy because of abdominal pain were found to have an intussusception involving the small intestine (16 cases) or caecum (11 cases). The clinical signs, operative findings and techniques adopted to overcome the obstruction are described. An evaluation of possible predisposing factors provided further evidence of the important role of the tapeworm Anoplocephala perfoliata in initiating intussusception involving the ileum and caecum.
This report describes the clinical and pathological features of 4 horses affected by caecocaecal or caecocolic intussusceptions associated with larval cyathostomiasis. In each case, there was clinical and/or pathological evidence of concurrent larval cyathostomosis. They all demonstrated variable signs including diarrhoea, pyrexia, weight loss and subcutaneous oedema and cyathostome larvae were identified in the faeces of 3 of the horses. These cases highlight the need to consider caecal intussusceptions as a possible complication in horses affected by larval cyathostomosis, especially where signs of abdominal pain are severe or persistent.
We tried to isolate verotoxin-producing Escherichia coli (VTEC) on sorbitol-MacConkey (SMAC) agar and in part by the polymerase chain reaction (PCR) method from sporadic enteritis patients with bloody stools and intussusception patients who came to three pediatric clinics in the Fukuoka area from October 1990 to September 1994. VTEC O157:H7 strains were isolated from 6 (10.5%) of 57 patients with bloody stools, Campylobacter spp. 15 (26.3%), Salmonella spp. 14 (24.6%) and Yersinia enterocolitica 2. We were not able to detect VT genes by PCR from 11 of 20 patients from whose stools no causative bacteria were isolated. Massive fresh bloody stools following frequent watery diarrhea were typical of the VTEC enteritis patients. Only 1 patient had fever and 2 had leukocytosis, but the C-reactive protein in all of them was below 1+. The VTEC strains were isolated during the summer season, 1 in June, 2 in July, and 3 in September. Since in the area O157:H7 appeared to be the most prevalent VTEC serotype, SMAC is very useful for screening VTEC in bloody stools. VTEC seems to be a rare pathogen of intussusception because the organisms were detected from none of the 30 patients.
BACKGROUND: It is widely believed that hydrostatic reduction of intussusception is less successful in children with prolonged symptoms prior to presentation. AIM: To prospectively evaluate success in relation to duration of symptoms. METHODS: Prospective study in which children, regardless of symptom duration, underwent an attempt at hydrostatic reduction. RESULTS: Of 113 children presenting with intussusception, 16 had peritonitis and required immediate laparotomy. A hydrostatic reduction was attempted in 97 and was successful in 77 (79%). There were 26 successful reductions with symptoms <12 hours (81%), 30 with symptoms for 12-24 hours (81%), and 21 with symptoms >24 hours (75%). CONCLUSION: The success rate with hydrostatic reduction was not significantly influenced by symptom duration.
