[Endoscopic peroral pancreatico-cholangioscopy in the diagnosis of diseases of bile ducts and the pancreas].

Till nowadays the diagnosis of biliary and pancreatic ducts disorders remains to be rather difficult. Cholangioscopy is the only method, that gives an opportunity of visual evaluation of the ducts. The results of 234 retrograde peroral pancreatico-cholangioscopies (RPCS) in 149 patients are analysed. 2 systems of the "Olympus" endoscopes, including both "mother" and "daughter" apparatus with uncontrolled (model PF-24, external diameter 2.4 mm) and controlled distal tip (model CHF B 20, external diameter 4.5 mm) were used for the tests. Endoscopic papillosphincterotomy has been performed in 87 of the patients, who were later on tested with RPCS (147 tests). 38 RPCS have been performed in 29 patients after transduodenal papillosphincterotomy. 47 cholangioscopic procedures have been undertaken in 31 patients after various types of biliodigestive anastomoses. In 2 cases RPCS has been performed after the balloon dilatation of the major duodenal papilla. The signs of catarrhal cholangitis have been observed in 27% of the cases. Purulent cholangitis was present in 13.4% of the patients. Cholangitis was detected in 19.5% of the cases in long-term follow up after endoscopic papillosphincterotomy; in 88.2% of such cases catarrhal inflammation of duct's mucosa was observed. It is stated that after endoscopic surgery cholangitis is observed 2.5 times less frequently, than after relevant transduodenal procedure.

[Results of various treatment modalities in the calculous cholecystitis].

Two alternative methods for the treatment of calculous cholecystitis are evaluated: extracorporeal lithotripsy was performed in 284 patients, laparoscopic cholecystectomy--in 130 patients. Even in strict selection of patients, lithotripsy was ineffective in 32 of them and they were subjected to an operation; in another group of patients elimination of the fragments from the gallbladder was incomplete. Therefore, extracorporeal lithotripsy may be used in no more than 10% of patients with cholelithiasis. Laparoscopic cholecystectomy was conducted in 130 patients. In 6 (4.5%) of them the operation had to be completed by laparotomy because complications occurred during the laparoscopic intervention. Laparoscopic cholecystectomy has some obvious advantages over open cholecystectomy: easier postoperative period, early activation of the patients, a good cosmetic effect. However, to determine the boundaries and possibilities of this method accumulation of experience is needed.

[Extracorporeal ultrasonic lithotripsy of biliary calculi].

The article analyses the efficacy of extracorporeal lithotripsy by a LT-01 piezoelectric lithotriptor (EDAP, France). A total of 72 lithotripsy sessions were performed on 37 patients, in 2 of them who suffered from chronic calculous cholecystitis the procedure was conducted on the day before the operation. As a method for treatment, extracorporeal lithotripsy was applied in 35 patients for the following indications: solitary and multiple stones measuring in sum no more than 3 cm in the satisfactory functioning of the gallbladder and patency of the bile ducts. In 35 patients the stones were crushed to fragments of various size. In 29 patients extracorporeal lithotripsy produced a marked effect and was the final method of treatment. Six patients were operated on (cholecystectomy) due to exacerbation of chronic cholecystitis in 4 patients, pancreatitis in one patient; total destruction of calcinated large stone fragments could not be achieved after 6 sessions in one patient.

[Ultrasonic endoscopic examination in pancreatic diseases].

Under analysis were 76 patients with diseases of the pancreas. The data of the ultrasonic endoscopic method were compared with operative findings in 49 patients and with the final clinical diagnosis in 27 non-operated patients. The correctness of the method in the group of operated patients was 80%, in non-operated patients 96.3%.

[Endoscopic papillosphincterotomy in the treatment of choledocholithiasis].

The article analyzes an experience with endoscopic papillosphincterotomy in 45 patients with recurrent or residual choledocholithiasis with/without stenosis of the major duodenal papilla. In 38 pathients stones were removed after endoscopic papillosphincterotomy or were eliminated spontaneously. In later terms none of the patients showed restenosis of the major duodenal papilla. Thus, endoscopic papillosphincterotomy is considered to be an effective method of treatment of choledocholithiasis.

[Fiber duodenoscopy and endoscopic retrograde pancreaticocholangiography in assessing the results of pancreatic resection and pancreatojejunostomy in chronic pancreatitis].

The endoscopic methods including retrograde pancreaticocholangiography were used for examining 78 patients, 14 of them were subjected to resection of the pancreas and 14 to pancreatojejunostomy. Gastroduodenitis was diagnosed in all the patients after resection of the pancreas, in 3 patients repeated surgical interventions (pancreatojejunostomy) were necessary. The examination of patients with pancreatojejunal anastomos has shown that scarring is more frequently found in terminolateral anastomoses while longitudinal pancreatojejunostomy is followed by good patency of the anastomosis.
