Adult intussusception is a rare condition, chronic and recurring in nature, and presenting as intermittent intestinal obstruction. Surgeons generally have limited experience with it. We present 13 cases that have been treated in our department over a period of 19 years. In most of the cases there is an identifiable cause and it is often a malignancy. Awareness, plain abdominal films, barium enema and CT are valuable tools for diagnosis. Resection without reduction is the treatment of choice in most cases. In instances where resection would necessitate a permanent stoma, attempts at manual reduction are justified. Timely treatment, properly carried out, should result in a good prognosis.

Infantile myofibromatosis (IM) is a distinct but rare clinicopathological entity occurring in neonates and infants. It probably represents a rare soft-tissue tumour made up of undifferentiated myofibroblasts. Its recognition is important since it can be mistaken for a malignancy when, in fact, it has a generally benign prognosis with spontaneous regression. We describe the first case of an infant with IM presenting with acute intussusception due to gastrointestinal as well as the typical skin involvement.

Adult intussusception is rare and is usually caused by a tumor serving as a lead point. Surgery is necessary to treat obstruction and rule out malignancy. However, if a benign cause (lipoma, fibroma, or Meckel's diverticulum) is suspected preoperatively, a minimally invasive surgical approach should be considered. This case illustrates the laparoscopic management of benign small bowel intussusception due to lipoma.

Trichobezoars are accumulations of hair casts in the stomach associated with trichophagia. The typical patient is an adolescent female who presents with alopecia and an upper abdominal mass which on moving can cause intermittent gastric outlet obstruction. Only a minority of patients have severe psychiatric disorders. When hair strands extend from the main mass in the stomach, all along the small bowel and reaching the cecum, the condition is termed the Rapunzel syndrome. In about 5% of patients there are separate hair masses in the stomach. The clinical presentation includes abdominal pain, loss of appetite, weight-loss, vomiting, loose stools, pancreatitis, jaundice, anemia and hypoalbuminemia. These signs and symptoms raise the suspicion of malignancy. Complications of bezoars include ulcers, perforation of the bowel, obstruction and intussusception. Diagnosis can be established either by barium swallow or by CT scan. Ultrasound might suggest the diagnosis, but sonographic features are definitely not pathognomonic. Treatment is surgical, as endoscopic removal is usually unsuccessful. We present 2 children in whom trichobezoars were found.

Leiomyosarcoma of the colon is a rare malignancy. We report the case of a 33-year-old woman with a leiomyosarcoma of the colon occurring as an intussusception 30 years after receiving abdominal irradiation for a Wilms' tumor. A review of the prior and current treatment for Wilms' tumor is discussed, as well as the association between second malignancies and abdominal irradiation. Leiomyosarcoma of the colon usually presents in the fifth and sixth decades of life and is more common in men. The most common symptom is pain. Ninety per cent are diagnosed at surgery for treatment of bleeding, perforation, or obstruction. Surgery remains the primary treatment. Leiomyosarcomas of the gastrointestinal tract are radioresistant, and adjuvant chemotherapy has shown no survival benefit. The overall prognosis is poor, with mean 5-year survival of 28 per cent. General surgeons need to be aware of the possibility of second malignant neoplasms after primary treatment of childhood cancers. Proper reporting is essential to study the long-term effects of early treatment of childhood cancers and in predicting the best treatment outcomes for these patients.

Chemopreventive effects of bovine lactoferrin (bLF), previously shown to strongly inhibit intestinal carcinogenesis in rats (K. Sekine, E. Watanabe, J. Nakamura, N. Takasuka, D.J. Kim, M. Asamoto, V. Krutovskikh, T.H. Baba, T. Ota, M.A. Moore, M. Masuda, H. Sugimoto, H. Nishino, T. Kakizoe, H.

Tsuda, Inhibition of initiation and early stage development of aberrant crypt foci and enhanced natural killer activity in male rats administered bovine lactoferrin concomitantly with azoxymethane, Cancer Lett. 121 (1997) 211-216), on spontaneous intestinal polyp development were assessed in the ApcMin mouse, a model for both familial adenomatous polyposis and sporadic colon cancers. In the experiment, 54 mice at 6 weeks of age were given 2% bLF (15 mice), 0.2% bLF (15 mice) and AIN-93G (24 mice) as basal diet ad libitum for 8 weeks. An overall tendency for a reduction in the total number of polyps in the small intestine was evident in the bLF-treated animals, along with significant suppression in the jejunum at the 2% dose (P < 0.05, 68% of the control). In addition, body growth suppression, presumed to be due to anemia and/or intussusception as a consequence of numerous polyps in the intestine, was alleviated. No toxic effects were observed in the intestinal epithelium. Although not as obvious as observed for the rat case, the data suggest that bLF may be a chemopreventor of intestinal polyposis.

Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by hamartomatous polyps in the small bowel and mucocutaneous pigmentation. Patients with Peutz-Jeghers syndrome often present as surgical emergencies with complications of the polyps, such as intussusception, bowel obstruction and bleeding. Furthermore, repeated operations may be needed in some patients, which may result in short bowel syndrome. Although early reports did not demonstrate a predisposition to cancer in patients with this syndrome, more recent studies have described an increased risk for both gastrointestinal and extra-gastrointestinal cancers. Women with the Peutz-Jeghers syndrome have the extremely high risk for breast and gynecologic cancer. Recently, Peutz-Jeghers syndrome susceptibility gene, encoding the serine threonine kinase STK11 (also called LKB1), was identified in families with Peutz-Jeghers syndrome. The identifications of germline mutations in families with Peutz-Jeghers syndrome could be a turning point in the management of Peutz-Jeghers syndrome.

Duodenal villous adenomas are extremely rare (1/5th of small bowel tumors). In view of their strategic position and risk of malignancy, they require definitive management in specialized care units. We report a case of a 35 year old female patient with a large duodenal (5 cm) villous adenoma causing intussusception of duodenum (a phenomenon rare because of its anatomic location & fixation).

A case of Peutz-Jeghers syndrome (PJS) in an African girl is presented to document the clinical presentation, management and follow up of this condition. The patient who presented with black buccal mucosal hyperpigmentation and clinical features of jejuno-jejunal intussusception was successfully managed by operative reduction of the intussusception and polypectomy. She is being followed up for evidence of malignant transformation in associated intestinal polyps and development of extra-intestinal malignancies at other sites. The management of PJS in light of recent trends is discussed, especially with reference to suggested protocols for screening and surveillance of sites at supposed risk of tumour development.

Peutz-Jeghers syndrome is an autosomal dominant inherited disorder characterized by hamartomatous polyps in the small bowel and mucocutaneous pigmentation. Patients with Peutz-Jeghers syndrome often present as surgical emergencies with complications of the polyps, such as intussusception, bowel obstruction, and bleeding. Recently an increased risk of malignancies has also been reported. This study was initiated to determine the clinical features of Peutz-Jeghers syndrome in Korean patients, with special attention to the development of malignancies. Thirty patients with Peutz-Jeghers syndrome were investigated; their median age was 23.5 years, and symptoms appeared at a median age of 12.5 years. Family history was positive in one-half of cases, and mucocutaneous pigmentation was observed in almost all patients (93%). The jejunoileum was the most frequent site of the polyps, and there were generally 10-100 polyps. Multiple laparotomies were performed in a substantial portion of the patients, due mainly to polyp-induced bowel obstruction, and the surgical interventions were begun at a relatively young age (average 21.4 years). Four cases of small-bowel cancer and one case of breast cancer were detected in probands, at a relatively young age (mean 36 years). Cancers of the small bowel, stomach, colon, breast and cervix were diagnosed in the first relatives of the probands. Close follow-up from an early age should thus be performed in patients with Peutz-Jeghers syndrome as they are at high risk of surgical emergency and development of malignancy.
