[Replacement of the extra-hepatic common bile duct in the dog by an elastomere silicone prosthesis. Its possible application in biliary surgery].

From an experimental study of the prosthetic replacement of the common bile duct in the dog by an silicone elestomere prothesis, according to the technic of double intubation with a 2 1/2 year follow up in the oldest cases, and complete reconstitution of a well-structured new bile duct, the author propose using a similar prosthesis in biliary surgery: --firstly, the carcinoma of the bile ducts, using an internal prosthesis hepatico-gastric, hepatico-jejunal or duodenal, which is eliminated internally; --secondly, in stenosis or operative wounds of the bile ducts, using either removable tutor prosthesis, or segmental prostheses lost internally.

[Segmental replacement of the prinicipal extra-hepatic bile duct in the dog using a silicone elastomere prosthesis].

The authors present an experimental series of prosthetic replacement of the common bile duct in the dog. The material used was silicone elastomere. In all the dogs studied, a new bile duct became formed around the prosthesis consisting of a fibrous tube covered with mucosa. The follow-up period in the first group of operated dogs was more than 2 1/2 years and in most dogs studied, there was neither biliary cirrhosis nor cholestasis. These encouraging results led the authors to suggest the operation in humans, particularly in carcinoma of the bile ducts.

Kron's biliary prosthetic bypass in the treatment of neoplastic jaundice.

After experimental study in the dog, which showed the material to be highly reliable, an original method of biliary bypass using a silicone prosthesis in the treatment of neoplastic jaundice is introduced. This prosthesis allows the bile duct to be bypassed regardless of the location of the obstacle. This method was used in 150 patients; recession was sufficiently good in 84 of them to confirm good tolerance and the excellence of the results. In fact, good results were recorded in 95% of cases of cancer of the hilum, which is all the more remarkable in consideration of the difficulties involved in these operations. The main postoperative complications are bile fistulas which resolve spontaneously if the precaution of extensively draining the zones of intubation is taken; postoperative comfort is excellent; no constraint is necessary and the operative risk is moderate, this is particularly desirable in patients in a poor general condition. A short prosthesis makes transtumoral intubation possible, and a long prosthesis allows implantation in the digestive tract: stomach, duodenum or first intestinal loop. Postoperative persistence of jaundice is rare if a prosthesis of sufficient diameter is used and if no major bile duct or part of the liver is excluded. Cholangitis is exceptional and indicative of an excluded biliary area.

[A new material and a simplified technic for treatment of recurrent or nonrecurrent bilateral hernias by the preperitoneal or subperitoneal approach].

Difficulties arise during surgical treatment of recurrent or non-recurrent bilateral hernia, the use of a median approach alone requiring the insertion of prosthetic material. Recurrence can be avoided if the material is reliable, and there is no risk of its migration or displacement. This applies to crinoplates, which allow the positioning of a relatively rigid but supple material of a size adapted to the pathological inguinal orifices, ensuring perfect reliability of this finally fairly simple operation. The use of two separate plates allows rapid surgery and a short incision, avoiding suprapubic eventration. The fact that the cord pierces the previously drilled plate prevents fixation and any risk of displacement, principal cause of recurrences. Excellent results without recurrence, and total lack of septic complications, were obtained in 200 cases operated upon by this method.
