[After low anterior rectal resection, colonic pull-through with delayed colo-anal anastomosis can avoid the need for a diverting ileostomy]

International audienceA delayed colo-anal anastomosis has been proposed as a way to avoid diverting stoma after low anterior resection. Surgical and functional results were reviewed in 17 patients operated between 1999 and 2007 using this technique. Complications included one colonic necrosis, two pelvic abscesses and one colovaginal fistula. Results of continence and quality of life scores were satisfactory. Rates of parietal and septic complications are low after delayed colo-anal anastomosis and functional results are good. The use of this technique is particularly effective to avoid diverting ileostomy and for use in patients with a high risk of pouch fistula

Which method to deliver hyperthermic intraperitoneal chemotherapy with oxaliplatin? An experimental comparison of open and closed techniques.: Experimental comparison of open and closed HIPEC

International audienceBACKGROUND: Hyperthermic intraperitoneal chemotherapy (HIPEC) achieves good results in selected patients with peritoneal carcinomatosis. There are two main procedures to deliver this therapy: the open abdomen and the closed abdomen techniques. A true comparison of the two techniques has never been performed. The aim of this study was to compare blood and abdominal tissue concentrations of oxaliplatin after open and closed techniques to deliver HIPEC. METHODS: Nine pigs underwent HIPEC at 42-43 degrees C for 30 min with oxaliplatin (400 mg/m(2)) according to two techniques: closed (three animals) or open (six animals). The open technique used either an external heater with a pump (three animals) or an intra-abdominal heating cable (three animals) to achieve hyperthermia. Temperature homogeneity, systemic absorption, and abdominal tissue mapping of the penetration of oxaliplatin with each technique were studied. Two additional pigs underwent hyperthermia with dyes instead of oxaliplatin to depict the distribution of the liquid within the abdomen with both techniques. RESULTS: Hyperthermia was satisfactory with both techniques. The closed technique achieved higher temperatures within the diaphragmatic area, while the open technique obtained higher temperatures in the mid and lower abdomen (P < 0.001 for both comparisons). The systemic absorption of oxaliplatin was higher with the open technique (P < 0.04 for all comparisons), as was the accumulation within the abdominal cavity. The operating time for the two techniques was not greatly different. CONCLUSIONS: Intraperitoneal hyperthermia can be achieved with both techniques. The open technique had far higher systemic absorption and abdominal tissue penetration of oxaliplatin than the closed technique
