[Intraoperative cholangioscopy].

Intraoperative fibrocholangioscopy (FCS) was used in 446 patients with cholelithic disease and acute cholecystitis. 399 (89.5%) of the patients were hospitalized urgently.

[Preoperative instrumental diagnosis of postoperative choledocholithiasis].

Experience in examination of 221 patients with postoperative cholangiolithiasis is discussed. Analysis of the results of instrumental examination ERPCG to surpass all the existing methods of diagnosis of stones in the bile ducts in informativeness and safety. A diagnostic algorithm of examination is suggested by means of which the necessary tactical problems connected with the forthcoming operation were solved in 98.

[Acute cholecystitis in the clinical picture of acute food poisonings].

The authors followed up 215 patients with acute cholecystitis who were hospitalized with an erroneous diagnosis of food poisoning and 346 food poisoning patients who developed acute cholecystitis in the course of the disease mentioned. Symptoms for differential diagnosis of acute cholecystitis and food poisoning were considered.

[The continuity between the polyclinic and the surgical hospital in rendering specialized medical care to patients with chronic calculous cholecystitis].

A thorough clinical analysis of pains in the right hypochondrium was carried out in 880 patients. There were 80 men (the mean age 45 years) and 800 women (the mean age 40 years). Three groups of the symptom complexes were distinguished, pointing to: (a) dyskinesia of the gallbladder by the hypotonic type; (b) dyskinesia of the gallbladder by the hypertonic type; (c) chronic cholecystitis.

[Recurrent and residual stones in the bile ducts].

Data of 205 patients with recurrent (48) and residual (157) choledocholithiases are presented. In most observations postoperative cholelithiasis proceeded by the type of chronic intermittent obturation of bile ducts. Highly effective method of diagnosing recurrent and residual calculi is thought to be the endoscopic retrograde pancreatocholangiography, best results of the treatment being obtained after the endoscopic papillosphincterotomy which should be used as the operation of choice.
