[Causes, diagnosis and surgical treatment of strictures of lobar and segmental hepatic ducts].

Causes of strictures of lobar and segmental ducts after their injuries during open and laparoscopic cholecystectomy in 53 patients were analyzed. For correction of bile outflow precision non-wireframe (n=22) and wireframe (n=20) anastomoses were used. In 10 patients a combined anastomosis was established. In 1 patient the external drainage of hepatic ducts was performed. After surgery 3 patients died. 1-15 year long-term results were studied in 48 (96%) patients. Good results were achieved in 29 (60.5%), satisfactory -- in 13 (27%) patients. Recurrences of the strictures were diagnosed in 6 patients. It is concluded that dynamic control is necessary in patients operated on for bile ducts injuries. Underestimation of remittent cholangitis leading to biliary cirrhosis worsens prognosis of the disease.

[Diagnosis and treatment of different types of high scar strictures of the hepatic ducts]. / Diagnostika i lechenie razlichnykh tipov vysokikh rubtsovykh striktur pechenochnykh protokov.

Results of treatment of 224 patients with scar strictures of the hepatic ducts (BSDH) are presented. Based on Bismuth's classification of BSDH E.I. Galperin (2002) proposed own one. According to this classification there were 17 (7,6%) patients with type "+2" (stump of common hepatic duct - CHD more than 2 cm), 26 (11,6%) - with type "+1" (stump of CHD 1 - 2 cm), 72 (32,2%) - with "0" type (stump of CHD less than 1 cm), 54 (24,1%) - with "-1" type (upper fornix of CHD confluence is not affected), 35 (17,4%) - with "-2" type (CHD confluence is destroyed), 20 (8,9%) - with "-3" type (strictures of segmental ducts). There were greater number of previous surgeries in the patients with "-1" and "-2" types (p<0,05). Jaundice and secondary biliary liver cirrhosis were seen more frequently in types "0" - "-3". Hepaticojejunostomy was the surgery of choice. For approach to unaltered wall of hepatic ducts (HD) section of lobar ducts in types "+1", "0", excision of portal plate and partial resection of IV hepatic segment (31 patients) in "-1" - "-3" types were used. Exchangeable transhepatic drainage (ETD) was applied in 31 patients due to impossibility to excise scar tissues completely. In early postoperative period 9 (4%) patients died due to purulent cholangitis (7 patients) and insufficiency of anastomosis (2 patients). Long-term results were evaluated in 180 (80,4%) patients from 1 to 14 (6,6+/-3,9) years of follow-up. Thirteen surgeries were performed for repeated strictures. The main cause of restrictures was inadequate resection of scar tissues and unreasonable refusal of ETD (7 patients). Developed surgical technique in different types of strictures permits to reduce postoperative lethality and the rate of restrictures.
