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 five-year survived case of more than 5 cm colorectal liver metastases treated with intraoperative microwave coagulation therapy].

A 54-year-old man underwent Hartmann's operation for rectal cancer in October 2003. Diagnostic images showed a single liver tumor in segment 7 of the liver in March 2004. He had a non-B, non-C cirrhosis. Liver damage was defined as B and ICG retention rate after 15 minutes was 54%. Platelet count was 7x10(4)-11x10(4)/mm3 and PT activity was 59%. The S7 tumor size was 6.5 cm in diameter, and we planned a partial resection of the liver. Intraoperative histological diagnosis of needle biopsy showed a metastatic adenocarcinoma from rectal cancer. Because of tuberculous peritonitis, it was difficult to control oozing from dissected plane. Therefore, we changed the method of operation from a partial resection to microwave coagulation therapy (MCT). To avoid a deteriorating liver function, we did not perform any adjuvant chemotherapy. He is alive without recurrence for five years after surgery. Nevertheless metastatic liver tumor is more than 5 cm and in cirrhotic liver, if the tumor located superficial parenchyma, MCT may have a possibility to be a curative treatment.

[Long-term survival case of advanced gastric cancer with paraaortic lymph node metastasis and peritoneal metastasis from S-1/CDDP combination therapy after reductive operation].

A 72-year-old female patient with type 5 gastric cancer in the upper gastric region underwent surgery. Due to paraaortic lymph node metastasis (#16a1, #16a2) and peritoneal metastasis, total gastrectomy and D0 lymph node dissection were performed. Surgical and pathological findings were poorly differentiated adenocarcinoma, INFbeta, pT3(SE), PM (-), DM (-), ly0, v2, sN3 (#7, #9, #16a1-a2), M0, stage IV. The patient was administered S-1 for 2 weeks at 80 mg/day, received 24-hour continuous intravenous infusion of 80 mg/day on day 8, and then discontinued chemotherapy for 2 weeks, which was regarded as one course. After one course, CT scan showed that the paraaortic lymph node metastasis had almost entirely disappeared. However, due to grade 3 neutropenia, and grade 2 nausea and anorexia in the first course, the treatment was changed to oral administration of UFT (400 mg/day) , which was discontinued one month later due to anorexia. The patient has been in good health without a recurrence for 4 years after surgery. This case suggests that reduction surgery combined with a S-1 regimen is an effective treatment for long-term survival.

Acute fulminant necrotizing colitis caused by amebiasis: report of a case.

Fulminating colitis rarely develops as a complication of amebiasis; however, it is difficult to diagnose and treat, and associated with a very high mortality rate. We report herein the case of a 62-year-old man with superacute fulminant necrotizing amebic colitis who, despite treatment with aggressive surgery and antiamebic agents, died of multiple organ failure following sepsis on the 25th day after onset. The patient had no immmunosuppressive disorders and claimed that he had never had homosexual intercourse, or traveled to the tropics in recent years. Since the incidence of amebiasis is increasing in developed countries, including Japan, more attention should be focused on the fulminating nature of this disease.
