Background Intussusception occurs when a segment of the bowel (the intussusceptum) telescopes into an adjacent segment (the intussuscipiens). Adult intussusception occurs rarely and often requires surgical resection for its treatment. We describe the case of an adult patient with extremely rare cecorectal intussusception treated using a novel combined transabdominal and trans-anal approach, which has not yet been reported in the literature. Case presentation A 71-year-old woman was transferred to our hospital for the treatment of upper abdominal pain. Physical examination, laboratory tests, and imaging inspections showed strangulated bowel obstruction induced by intussusception associated with the intra-rectal mass. We performed an emergency operation and treated the intussusception using a combined transabdominal and trans-anal approach. The intraoperative findings revealed bloody ascites and a potentially malignant tumor that had moved toward the anal side from peritoneal reflection. The tumor served as the lead point in the cecum with mobile cecum. After reducing the intussusception using the combined procedure, we removed the ileocecal portion. The intraoperative and histopathological findings suggested that cecum cancer with mobile cecum had caused the cecorectal intussusception. The patient had an uneventful postoperative course, except for postoperative pulmonary pneumonia. Conclusion To the best of our knowledge, this is the first reported case of adult cecorectal intussusception due to cecum cancer with mobile cecum successfully treated using the combined transabdominal and trans-anal approach. This combined procedure may be useful in treating the intussusception where the lead point is distal from the peritoneal reflection.

The results of treating 12 consecutive patients with unresectable colorectal hepatic metastases with a hepatic arterial infusion of high-dose Adriamycin, 100-120 mg/m2, using hepatic venous isolation (HVI) and charcoal hemoperfusion (CHP) are reported herein. Adriamycin was administered over 5-15 min under extracorporeal drug elimination by HVI-CHP. HVI was percutaneously accomplished by either the double-balloon technique using a Fogarty occlusion catheter (8/22F) or a balloon-tipped catheter (16F). During the infusion, isolated hepatic venous blood was filtered by CHP and pumped into the left axillary vein. There were no lethal complications, and good hemodynamic tolerance to HVI-CHP was confirmed. Tumor liquefaction accompanied by a sharp decrease in serum carcinoembryonic antigen levels by more than 50% of pretreatment levels was observed in 6 of the 12 patients 1 month after treatment. Apart from chemical hepatitis, which developed in 11 (92%) of the patients, the Adriamycin toxicities were well controlled following the development of nausea and vomiting in 2 patients (17%), leukopenia < 2,000/mm3 in 3 (25%), and gastric ulcer in 1 (8%). These results indicate that this method is a safe and useful procedure for otherwise hazardous high-dose intra-arterial chemotherapy in patients with unresectable hepatic tumors.
