Recent experience with 4 cases of adult intussusception is described with a review of the literature. Case 1: A 79-year-old man was admitted to the hospital because of a right under abdominal pain and diarrhea. Barium enema, abdominal ultrasonography and CT indicated an intussusception at the ileocecal region. On laparotomy, intussusception extending to the ascending colon was noticed, and right hemicolectomy was carried out. The leading point was the ileum, which was 14cm oral side from the terminal ileum. There was no tumor in this area. Case 2: A 33-year-old woman had an ileocecal intussusce-ption due to a cecal malignant lymphoma, and underwent right hemicolectomy. Case 3: A 52-year-old man had a colonic intussusception due to a cancer of the ascending colon, and underwent right hemicolectomy. Case 4: A 63-year-old man had a colonic intussusception due to a rectal cancer, and underwent low anterior resection.

We experienced a case of anal canal cancer with periproctal Paget disease in which conservative treatment was effective. An 86-year-old man complining of anal bleeding was diagnosed as having an anal canal cancer by elsewhere, and was referred to the hospital. This case is essentially a possible canditate for abdominoperineal rectal resection, but conservative therapy was employed because of his advanced age and association of dementia. The patient was administered doxifluridine 800 mg orally for consecutive 4 weeks, was applied 5-FU ointment locally, and received radiation at a dose of 2Gy a day 20 times, totally 40Gy. Consecuently the anal canal cancer and Paget disease completely disappeared 4 weeks and remission of erosion around the anus was attained 8 weeks after the therapy. These findings indicate that we can choose more positively a combination of chemotherapy and radiation therapy which permits the anal function to be preserved in the treatment of anal canal cancer.

A case of papilloma of the gallbladder is reported. The gallbladder was associated with cholesterosis but not with stones. The causes of colicky pain in this case are discussed. Papillomas of the gallbladder exhibit no characteristic clinical picture; the symptoms are similar to those of any type of gallbladder disease. Papillomas of the gallbladder may be associated with malignant degeneration. Cholecystectomy is the treatment of choice.
