Long-term results of intersphincteric resection for low rectal cancer in Japan.

Intersphincteric resection (ISR) is the ultimate sphincter-preserving procedure for low rectal cancer. A questionnaire about the standardization of ISR was given to 2125 patients who underwent curative ISR for low rectal cancer between 2005 and 2012 at 127 affiliated institutions of the Japanese Society for Cancer of the Colon and Rectum (JSCCR), and the results were compared with the results of a systematic review. The findings revealed that although mortality and morbidity were relatively low and the survival rate after ISR was good, the rates of local recurrence and postoperative fecal incontinence were relatively high. The radicality of ISR was compared with that of abdominoperineal resection and low anterior resection using the propensity score matching prognosis analysis of patients in the JSCCR nationwide registry. The local recurrence rate was significantly higher after ISR, and especially high in patients with T3 (invasion into the external anal sphincter) and T4 disease. These results provide evidence about the factors related to fecal incontinence after ISR. As measures for the standardization of ISR, it is important to reconfirm that ISR is not indicated for patients with cT3 and cT4 disease and those with poor preoperative defecatory function, based on the ISR indication criteria.

[A case of huge omental-origin liposarcoma controlled by a combination of ifosfamide and adriamycin].

A 51-year-old woman came to our hospital after a medical check -up. She suffered from abdominal distension. Abdominal CT revealed the abdominal cavity filled with omental cake. The preoperative diagnosis was unassertive. Laparotomy through midline incision was performed. The bulk of the omental tumor occupied the abdominal cavity, but infiltrated the bowel or abdominal wall less. Fractional resection of the tumor, right hemicolectomy, sigmoidectomy, wedge resection of small intestine and left ovariectomy were performed in parallel. Resected specimens weighed 6. 6 kg in total. The operation was considered palliative because of the peritoneal dissemination. Postoperative intraabdominal administration of cisplatin(50mg) made the ascites disappear. She was discharged 3 weeks after the operation. The final diagnosis was liposarcoma(myxoid type), and 5 courses of adjuvant chemotherapy with adriamycin and ifosfamide were performed. No relapse was found 11 months after the operation, but tumor regrowth occurred in the thoracic and abdominal cavity and the patient died 14 months after the operation.

[A case of diffuse peritoneal malignant mesothelioma--intraabdominal administration of cisplatin is useful for diminishing ascites].

A 59-year-old man with a history of exposure to asbestos suffered from abdominal distension and visited our hospital. Abdominal CT revealed vast ascites but there was no obvious primary lesion. Serum tumor markers and hyaluronate were within the normal range. Abdominal puncture was carried out, and cytology of ascites was negative. We suspected diffuse malignant peritoneal mesothelioma because hyaluronate in ascites rose to 10×104 ng/mL. Ga-scintigraphy and FDG-PET were negative. We performed laparoscopic observation for definite diagnosis and found fine white particles at the peritoneum. The result of biopsy was malignant mesothelioma. The patient underwent intraperitoneal administration of cisplatin and his ascites was diminished. He lived for a year with no recurrence but died 23 months after diagnosis because of progression of pleural mesothelioma and liver metastases. Relapse of ascites was not found in the entire clinical course. Cisplatin administration in the peritoneal cavity is thus very effective in preventing progression of ascites.

[Case of indwelling catheter dislocation into the duodenum during hepatic arterial infusion chemotherapy].

A 44-year-old man underwent hepatic arterial infusion chemotherapy and systematic chemotherapy using fluorouracil (5-FU) for recurrent liver metastasis of colon cancer. He reported upper back pain 38 weeks later. Arteriography using a port system revealed a dislocated catheter tip in the second part of the duodenum. Conservative therapy using antibiotics was employed without removing the catheter tip. Various complications related to intrahepatic arterial infusion chemotherapy have been reported. Catheter chip dislocation is rare, but can sometimes become a severe complication, thereby warranting careful follow-up after hepatic arterial infusion chemotherapy.
