[Choice of suture material for surgery on the biliary system].

To study the most biologically inert sutural material under the conditions of choleintestinal anastomoses, 3 series of dog experiments were performed. Terminolateral choledochoduodenoanastomoses were established in all the animals. To establish the first layers of sutures in the first series (25), use was made of catgut, in the second series (25) of silk, and in the third one (25) of capron. To establish buried sutures, use was made of silk 3. Macro- and microscopic studies of anastomoses were made 3, 7, 15, 30, 90, 180 and 360 days after operation. Histological and histochemical studies of the sections of the anastomosis demonstrated that the morphological appearance around sutural material in question was strikingly different. The capron thread appeared the most inert under contact of alimentary juices with a highly irritant action. It is advisable that such a thread should be widely used in surgery on the biliary ducts.

The results of 1000 intracapsular cataract extraction with the suture-fixated Medallion lens implant.

One thousand intracapsular medallion implants, performed between August 1975 and July 1980, were analyzed for complications (minimum follow-up 6 months): cystoid macular edema, 6.5%; retinal detachment, 2.8%; corneal edema, 0.9%; aphakic glaucoma, 2.5%; suture failure, 9%; implant subluxation, 3.7%; implant dislocation, 2%; and implant removal, 0.6%. Visual acuity of 20/40 or better was achieved in 93.4% of the cases, excluding non-implant related causes of low visual acuity.

[Causes of anastomositis after gastric resection].

The control fibrogastroscopy of the resected stomach in patients showing the clinical picture of postoperative anastomositis has proved that the application of an unresolving suture material (caprone) for a marginal suture of gastroenteroanastomosis causes post-resection inflammation of anastomosis in about 50% of cases. For improvement of surgical results the authors suggest to substitute marginal caprone sutures with catgut or tantal agraffes.
