The causes of melena or hematochezia in 48 pediatric patients were examined. Malrotation with volvulus was an important cause of hemorrhage during the newborn period, and intussusception was very typical in patients aged from 1 month to 1 year. Polyps of the rectum and colon were the most common causes of melena or hematochezia in patients older than 1 year. No cause of melena or hematochezia could be identified in 11 children. Ten patients have remained in good health with no further episodes of melena or hematochezia. Localized multiple polyps of the rectum with focal carcinoma were detected in only one patient. In general, although no further investigation is required after detection of the cause of bleeding and its successful treatment, it should be kept in mind that gastrointestinal malignancy can occur in children.

Enteroclysis patterns encountered in four patients with adult intestinal intussusception of different etiology--including a leiomyoma, a Peutz-Jeghers hamartoma, a metastatic colon carcinoma, and adhesions--were analyzed and compared to surgical and pathological findings. Emphasis was given not only to radiological signs indicative of impaired circulation but also to the preoperative evaluation of the stimulating cause. A "stretched spring" pattern, corresponding to increased distance between large and thick concentric rings, was found to conform to a stage of strangulation with exudation, whereas sharply demarcated fine rings in close proximity were suggestive of the absence of vascular impairment. The morphology of the underlying lesion was also shown to conform to the dynamic appearance of the intussusception. Benign submucosal, intraluminal tumors led to a long, rather permanent intussusception, with the tumor being the leading point; whereas intussusception associated with annular malignancies or adhesions was shorter and transient or partial, as fixation was present. The cause of the intussusception was correctly identified preoperatively in each case; the vascular compromise involved was also indicated, and the correlation between radiological appearances and morphology at pathology specimens was excellent.

A case of intussusception due to a carcinoma of the cecum during pregnancy is reported. A 27-year-old pregnant female was admitted to Shimodate Municipal Hospital because of abdominal pain, nausea and vomiting. Her abdomen was distended, and a relatively hard mass was palpable in the right hypochondrium. Following a diagnosis of intussusception by ultrasonography, a laparotomy was performed. The lesion causing the intussusception was found to be a carcinoma of the cecum, and thus a right hemicolectomy with lymph node dissection was carried out. Histological examination revealed that the tumor was a well-differentiated adenocarcinoma which had invaded the muscularis propria but was superficial to the subserosa. None of the lymph nodes were cancerous. The incidence of colonic cancer above the peritoneal reflection during pregnancy is very low. Only 24 cases have been previously reported; our patient is only the 25th case, as well as being the first case demonstrating Dukes' A. Due to the intussusception, ultrasonography was effective for diagnosis and the patient was able to undergo a curative operation at an earlier stage than other patients.

Intussusception secondary to metastatic sarcoma is an unusual cause of small bowel obstruction. When a patient who has no history of a previous laparotomy, and has a known malignancy which metastasized hematogenously, presents with small bowel obstruction, the diagnosis of intussusception should be considered. The patient should be evaluated and treated accordingly.

From 1983 until July 1994, 561 patients in 2 urology departments (Mainz and Wuppertal) underwent a Mainz pouch 1 procedure. The Mainz pouch 1 was used for bladder augmentation in 60 patients, for orthotopic bladder substitution in 61 patients, and for continent cutaneous urinary diversion in 440 patients. In the group of continent cutaneous urinary diversion, the continence mechanism applied was an ileal intussusception nipple in 270 patients, an appendix stoma in 146 patients, a submucosal seromuscular bowel-flap tube in 14 patients, and a submucosal full-thickness bowel-flap tube in 10 patients. Indications for urinary diversion were bladder cancer in 339 patients, anatomical or functional loss of bladder capacity in 179 patients, and other primary or secondary malignancies of the bladder or true pelvis in 43 patients. After a mean follow-up period of 57 months (range, 3-127 months), early and late complications were encountered in 12% and 37% of the patients, respectively. In the bladder-augmentation group, 93% of the patients are completely continent day and night. All but three patients, who empty their reservoir by intermittent self-catheterization (CIC), void spontaneously by abdominal straining. In the orthotopic bladder-substitution group, 95% of the patients are continent during the daytime. To prevent urinary leakage, 13% have to empty their reservoirs regularly at 4-h intervals and 13% have to perform CIC to avoid residual urine. Among the patients treated with continent cutaneous urinary diversion, stoma failure occurred in 11%, stoma stenosis was encountered in 13% and required open revision in 2%, endoscopical incision in 10%, and conservative treatment (dilation) in 1% of cases.

Metastasis of lung cancer to the digestive tract (excluding the esophagus) was confirmed by surgery or autopsy in 30 of the 1635 lung-cancer patients admitted to this Center during the 17-year period since 1977. The diagnosis was made before death in 7 and after death in 23. Metastasis of large cell carcinoma was the most common (3.7%), followed by adenocarcinoma (2.4%), small cell carcinoma (1.7%), and squamous cell carcinoma (0.7%). Metastasis to the stomach occurred in 0.4%, to the small intestine in 1.1% and to the colon in 0.5%. The overall percentage of metastasis to the digestive tract was 1.8%. Among the 298 cases diagnosed at autopsy, metastasis to the digestive tract occurred in 9.7%; stomach, 2.6%; small intestine, 5.7%; and colon, 3.0%. Eleven of the patients in whom the diagnosis was made at autopsy had abdominal symptoms while they were alive. In 11 cases diagnosed at autopsy, occult blood was positive in 9, but 6 of those 9 patients were asymptomatic. The occult-blood test is considered to be helpful as a supplementary diagnostic method in detecting metastasis of lung cancer to the digestive tract. Among the cases diagnosed while the patients were alive, metastasis was observed in the small intestine in 6 and in the colon in 1. The major manifestations were melena, ileus, intussusception, and perforation; 4 patients required emergency surgery. The prognosis was poor: the mean survival period from the onset of symptoms was 49 days. The direct cause of death was metastasis to the digestive tract in 5 cases. The possibility of metastasis to the digestive tract is high when progressive abdominal symptoms are observed and the stool is persistently positive on occult-blood tests.

A 7-week-old boy presented with a 6-week history of failure to thrive, acute intestinal obstruction, and an apparently irreducible intussusception (noted on contrast enema). He underwent abdominal exploration, during which a cecal mass was identified and resected. The mass proved to be a leiomyosarcoma. Histologically, it was an intermediate-grade malignancy with a predicted 5-year survival rate of 16% to 23% based on data from the adult experience. Three years after resection and without having received adjuvant therapy, he is healthy and free of disease. A review of the literature showed that in infants these tumors are predominantly colonic, compared with the predilection for small intestinal lesions found in the older pediatric and adult populations. Infantile intestinal leiomyosarcomata are rare malignancies that do well if complete surgical excision of the disease can be accomplished. The histological prognostic indicators proposed for intestinal leiomyosarcomas in the adult population cannot be extrapolated to infants because when they occur in infants, they appear to be less aggressive, and these patients do well without adjuvant therapy.

Colorectoanal intussusception is a rare and distinct entity that differs from the more common rectal prolapse. Typically intussusception occurs with tumor at the apex of the intussuscepted segment acting as a lead point. Only 26 adult cases of this entity have been reported in the literature. All have been associated with a benign or malignant tumor. Here we present a case and review the literature of colorectoanal intussusception. The case presented is that of an elderly woman with a large circumferential villous tumor at its apex. Perineal resection was performed in a single stage with intravenous sedation without complication (figures). This represents only the second reported case in the English literature of a colorectoanal intussusception treated in this manner.

The first case of adenocarcinoma developing in a continent ileostomy is reported. A healthy, 39-year-old man with a continent ileostomy for 17 years developed subacute obstructive symptoms and was found on endoscopy to have a large adenocarcinoma involving the intussusception valve. At operation, he was found to have a large tumor originating in the valve, extending through the reservoir, and involving the afferent ileal limb. A number of metastatic lymph nodes were identified in the mesentery of the small bowel. He underwent excision of the pouch and formation of an end ileostomy. He is currently undergoing adjuvant chemotherapy. Biochemical and morphologic changes in the ileal pouch, both in the pelvis and the continent ileostomy, are discussed. The implications of this apparent de novo cancer arising in an ileal pouch are discussed.

Whether melanoma develops as a primary tumor in the small bowel remains controversial. A 57-year-old male Japanese presented signs of intestinal obstruction. Ultrasonography and computed tomography disclosed an abdominal mass with multiple concentric rings, characteristic of intussusception. At surgery, a spherical tumor, 3.8 cm in diameter, with scattered pigmentation was found to lead the intussusception. Segmental intestinal resection with regional lymph node dissection was performed. Pathological examination revealed diffuse infiltration of malignant melanoma cells. Nodal metastasis was seen only in the mesenteric node draining from the tumor-bearing intestinal segment. Twelve months after surgery, melanoma recurred in the liver and para-aortic lymph nodes, where a malignancy of the digestive organs frequently metastasizes; however, no extraperitoneal melanoma was found after repeated examinations. Thus, this case suggests that primary malignant melanoma can originate in the small intestine and be a cause of intussusception in the adults.
