A randomized clinical trial of surgical drainage in thyroid surgery was performed with 97 patients. Using equivalence testing it is reported that morbidity was not significantly different between the two groups and the length of hospital stay was shorter in the undrained group. It is possible to perform thyroidectomy without drainage in a selected population.

27 patients were admitted in the Digestive intensive care unit of Croix-Rousse Hospital after a massive bowel resection (residual bowel 120 cm). The etiology was of vascular origin in 15 cases. The length of intestine was nil in 4 cases, between 20 and 50 cm in 12 cases, and between 50 and 120 cm in 11 cases. A colon resection was performed in 20 cases. For 5 patients, a "double temporary intestinal stoma" for ischemic bowel was made. A "second look laparotomy" was performed in 11 cases. The definitive intestinal continuity restauration was made in 23 cases (7 immediately, 16 later) with 3 duodenocolic anastomoses. 8 patients were able to find back a oral alimentation. 19 patients (with 4 total bowel resections) received a home parenteral nutrition. Actually, 11 are alive.
The hemostatic potential, tolerance and handiness of a new generation of hemostatic sheets (Hemostagene) were compared with those of reference collagen sheets in a randomized parallel-group multicenter study. Both types of hemostatic sheets, issued from calf derm, have been evaluated in digestive and neurosurgical pathologies. The comparability of both groups (52 patients in the Hemostagene group A, 54 in the reference group B) has been verified on morphological data, coagulation records and hemostasis conditions. The time required to achieve hemostasis was slightly, yet not significantly, shorter in group A (3 min 27 sec) than with the reference sheet (4 min 10 sec). This new sheet was judged significantly handier than the reference sheet. Adherence to the gloves and instruments was very significantly (p less than 0.0001) more frequent in the reference group B than in the group A. Both collagen sheets have quite similar clinical, biological and immunological tolerances which confirms the literature data. So, this new sheet, together with an hemostasis at least as good as the one obtained with the reference sheet, brings a highly improved handiness.

Tolerance of intraperitoneal chemohyperthermia (IPCH) with mitomycin C (2 mg/kg) by irrigation of the peritoneal cavity via a closed circuit system was evaluated in Beagle dogs for possible use in the management of human peritoneal carcinomatosis. Of dogs, 24 underwent three digestive anastomoses each. They were randomized into three groups: control (n = 6), intraperitoneal hyperthermia (n = 8) and IPCH (n = 10). Peritoneal temperatures were maintained between 41-43 degrees C for 60 min. Tolerance was evaluated through clinical follow-up, biological samples (serum electrolytes, blood counts and serum enzymes), histological examinations and post-mortem macro- and microscopic controls of anastomosis. Mortality and morbidity rates were not different in the three groups. No anastomotic leakage occurred. Evidence of biological toxicity was minimal. Histological examinations showed no definitive tissue damage. IPCH appears to be a safe and reliable device in dogs. Plans to combine IPCH with MMC in surgical resection of patients with peritoneal carcinomatosis are underway.
A randomized clinical trial of surgical drainage in thyroid surgery was performed on 97 patients. Morbidity was not significantly different between both groups. The length of hospital stay was shorter in the undrained group. However, this RCT is not an indication of the value of drainage after thyroid surgery because the series is too small. Using a meta-analysis of the RCTs reported it is possible to show that to drain is not useful.
