[Results of transduodenal papillosphincterotomy and double internal drainage of the common bile duct using the SPP-20 device].

: The authors discuss the immediate and late results of operations conducted with the [symbol: see text] suturing instrument of their design. It made possible one-stage transduodenal papillosphincteroplasty by application of two rows of tantalum staple sutures with division of the tissue between them--papillosphincterotomy. The authors conducted the operation on 242 patients for benign stenosis of the common bile duct by stones incarcerated in it. In 29 patients the intervention was complemented by the formation of supraduodenal choledochoduodenoanastomosis by means of the same suturing instrument, establishing in this was double internal drainage of the bile ducts. The suturing instrument made the operation easier and atraumatic and provided reliable hemostasis. Immediate postoperative mortality as 1.9%. Transduodenal papillosphincterotomy with the [symbol: see text] suturing instrument produced g od and satisfactory results in 95.2% and poor results in 4.8% of patients; poor late results of double drainage of the choledochus by the authors' method were not registered.
