Insertion of self-expanding metallic stent for palliative treatment of colorectal neoplastic stenosis is not a widespread method. We report two cases in whom the endoscopic stent insertion was successfully performed without incident. Migration of the stent and rectal bleeding in one patient were observed within a follow-up of 7 and 10 months that was ended by colostomy in both patients. These two cases confirm that this endoscopic technique can be proposed as an alternative to usual palliative treatment by phototherapy laser.

Intra-operative radiation therapy (IORT) is a multidisciplinary approach in which residual tumors or tumor beds are directly irradiated during a surgical procedure. To evaluate its efficacy we conducted since 1985 a prospective study including non metastatic gastric adenocarcinoma treated by surgery, IORT (15 Gy) and post-operative external beam radiotherapy (44 Gy). Up to now, 45 gastric adenocarcinomas (18 pNO and 27 pN1N2) have been included in the study. Mortality and morbidity rates were not different from those of surgery alone. Overall 5 year survival rate is 59.1% and pN1N2 5 years survival rate is 50.6%. These promising results are comparable with those of asian randomized studies which demonstrate the possible value of IORT in the treatment of gastric adenocarcinoma.

One new case of post-traumatic hematobilia due to an arteriobilary fistula is reported. This etiology is relatively rare, and its diagnosis is sometimes difficult if the three signs: pain, bleeding and jaundice are not observed. The most effective paraclinical examination still is selective arteriogrpahy, which makes the diagnosis possible, accurately locates the fistula and sometimes allows hyperselective embolization, as it did in this case. The use of embolization for the treatment of post-traumatic hematobilia due to an arteriobiliary fistula reduces operative mortality for this disease, which still has a poor prognosis.
