[Immediate, early and late results of endoscopic papillosphincterotomy]. / Neposredstvennye, blizhaisie i otdalennye rezul'taty éndoskopicheskoi papillosfinkterotomii.

Clinico-instrumental examination of 226 patients showed that there were no fatal outcomes directly after endoscopic papillosphincterotomy, the number of complications was approximately the same as after transduodenal operations on the major duodenal papilla but they took a much easier course. The high effectiveness of an endoscopic operation was confirmed in the immediate postoperative period (absence of biliary hypertension, jaundice, pancreatitis, cholangitis). In the late-term periods after EPST restenosis was rarely encountered (3.9%); duodeno-biliary reflux caused no serious disorders, while the functional activity of the sphincter Oddi which had been operated on was partly maintained in 84.2% of patients.

[The value of ultrasonic and x-ray endoscopic methods in the diagnosis of acute surgical diseases of the abdominal organs]. / Znachenie ul'trazvukovogo i rentgenoéndoskopicheskikh metodov v diagnostike ostrykh khirurgicheskikh zabolevanii organov briushnoi polosti.

The authors discuss experience in the complex use of ultrasonic and radio-endoscopic methods of examination in 820 patients who were admitted to the hospital with acute surgical diseases of the abdominal organs. Instrumental methods of diagnosis were used, which began with ultrasonic examination. The correct diagnosis of the disease was often established by this method, further examination of the patient was planned, and more concrete indications for invasive radio-endoscopic studies were determined by means of which precise data on the identified pathological process were revealed and, sometimes, adequate therapeutic measures were also ensured. Reduction of the duration of the diagnostic period to 2-3 days was the most important result of the use of these methods in the examination of patients with acute diseases of the abdominal organs.

[Roentgenocontrast study of pancreatic ducts in surgery of the pancreatic-biliary system]. / Rentgenokontrastnoe issledovanie protokov podzheludochnoi zhelezy v khirurgii pankreato-biliarnoi sistemy

The authors report the data obtained as a result of exploration of the main pancreatic duct pre- and intraoperatively. The study was carried out in 34 patients with pancreatic fistulas. Endoscopic catheterization of the papilla duodeni was undertaken in 80 patients, it proved to be a success in 71. Pancreaticograms was made in 63 observations. Contrasting of the duct of Wirsung was noted in 167 of 263 patients in whom operative cholangiography was performed. The data obtained indicated that pre- and intraoperative pancreaticography is a valuable method of investigation, which aids in determining surgical policy in chronic pancreatic lesions and in formulating rational grounds for direct operative interventions on the pancreas.

[Structure and histochemical characteristics of the mucosa of the Vater's ampulla in man (according to materials of aimed biopsies)]. / Stroenie i gistokhimicheskie osobennosti slizistoi obolochki Faterova sosochka cheloveka (po materialam pritsel'nykh biopsii)

Examination of 52 aimed duodenal biopsies has revealed that there are several variants of the structure of the Vater's papilla mucous membrane. In a number of cases it is identicalto the mucous membrane of the duodenum. In 20 cases the Vater's papilla was covered with mucoid epithelium which was histochemically similar to the epithelium lining the stomach, bile ducts and the gallbladder. The "intermedial" forms found in these cases appearedto be capable to change into mucoid or edging epithelium. The mucous cells occasionally found in the Vater's papilla epithelium might be a variation of goblet cells. It seems that they are secreting by holocrine type.
