[Surgical tactics in cholangitis in middle-aged and elderly patients].

The authors analysed the results of examination and treatment of 399 elderly and old-aged patients in the period between 1971 and 1981. At that time cholangitis was managed in 146 (36.6%) patients mainly by surgical intracavitary operations, in 21.2% with a fatal outcome. The results showed the high risk of surgical methods for treatment of cholangitis. Since 1982 the authors have introduced into every-day practice endoscopic methods for the management of this disease. It was found that endoscopic papillosphincterotomy (EPST) is the most physiological and safe method for the treatment of choledocholithiasis, stenosis of the major duodenal papilla, and acute cholangitis. EPST undertaken in 253 (63.4%) patients ensured adequate decompression of the bile ducts in 187 (73.9%) of them and facilitated removal of cholangitis and recovery. With the use of EPST in the treatment of acute cholangitis not only was the number of surgical operations on patients of the older age group reduced, but the mortality decreased to 5.5% (which was 3.9 times lower than the mortality in management of cholangitis by surgical operations).

[Detoxication therapy in diffuse suppurative peritonitis].

Results of treatment of 284 patients operated upon for diffuse peritonitis are presented. The assessment is given of the significance of detoxication methods--forced fractionated peritoneal dialysis and washing of the abdominal cavity in treatment of diffuse peritonitis and their influence upon the outcome of the disease.

[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.

[The morphological changes in the eye tissues of rabbits in transconjunctival-scleral cyclocoagulation by the radiation of a krypton laser operating continuously].

The paper describes a morphologic picture of changes in eye tissues of rabbits in transconjunctival scleral action on the ciliary body by means of krypton laser (wavelength--647.1 nm) working in a continuous regime. The applications were located 1.0-1.5 mm from the limbus with energy--0.8--3.0 Wt, exposition time--2.0 sec., spot diameter--1000 mcm. The degree of necrosis of ciliary epithelium and atrophy of ciliary processes are directly dependent on the dose of action. Thus, the greatest part of laser radiation with 647.1 nm wavelength is absorbed at the level of the ciliary body. In perspective, this can lead to development of new methods for treatment of some eye diseases, such as glaucoma, tumors of the uveal tract, etc.

[Diagnosis and treatment of acute cholecystitis complicated by local peritonitis].

The article analyses 610 patients with acute cholecystitis complicated by circumscribed peritonitis which determines the results of surgical treatment in many patients. The clinical manifestations of circumscribed peritonitis complicating destructive cholecystitis are discussed. It is shown that laparoscopy plays a role in the early diagnosis of atypical or asymptomatic course of this complication, particularly in elderly and old-aged patients. Data on the surgical treatment of acute cholecystitis complicated by localized circumscribed and ++non-circumscribed peritonitis are presented. The authors show the possibility of choosing the optimal operation--laparoscopic drainage of the gallbladder and abdominal cavity--in the first stage of treatment of patients with phlegmonous cholecystitis and localized ++non-circumscribed peritonitis in the presence of serious concomitant diseases.

[Evaluation of late results of surgical treatment of choledocho- lithiasis].

An experience with repeated examinations of 656 patients operated upon for bile calculi is presented. It was shown that the estimation of long-term results of surgical treatment of choledocholithiasis should be performed on the basis of common criteria three years after operation by complex use of clinical, laboratory, X-ray and endoscopic methods of examination. Debatable questions associated with the interpretation of special examinations and their influence on the clinical estimation of long-term results are elucidated.

[Late results of the surgical treatment of patients with biliary calculi].

The authors analyse the late results of surgical treatment of 463 patients who underwent operation for stones in the bile ducts. The late results were found to be determined by the character of the affection of the bile excreting system and the rational choice of the operative method. The indications and contraindications for various methods of treating cholelithiasis were determined more precisely from study of the late results.

[Treatment of nontumorous obstructive jaundice and cholangitis in middle-aged and elderly patients].

On the basis of examination and treatment of 364 elderly and senile patients with obstructive jaundice and cholangitis, the authors conclude that the frequency of these complications is high and that cholangitis takes an atypical course in patients over 60 years of age. They determine the significance of the respiratory insufficiency syndrome in manifestation of the severity of the disease. In view of the high risk of surgery at the peak of jaundice and cholangitis, the authors suggest the wide use of endoscopic papillosphincterotomy according to indications for correcting biliary hypertension. It proved to be one of the most effective methods in the treatment of jaundice and cholangitis, contributed to reduction of the number of surgical operations on cavities and to a 4.4-fold decrease of postoperative death rates among this contingent of patients.

[Acute cholecystitis and its complications].

The results of operative treatment of 4,011 patients with acute complications of cholecystitis are analysed. Problems of diagnosis and tactics and the results of treatment are discussed. It is pointed out that the management of patients with acute complicated cholecystitis is a great and urgent problem in abdominal surgery in view of the diffuse character of the process.

[Late results of supraduodenal choledochoduodenostomy in the light of clinico-rentgenological and clinico-endoscopic findings].

The authors discuss remote results of choledochoduodenostomy in 105 patients examined clinically, rentgenologically and endoscopically for 1--7 years. Good and excellent remote results were obtained in 87,6% of patients. Poor and staisfactory results were shown by patients with stenosis of anastomosis and recurrent pancreatitis. One of the causes of jondice and cholangitis is an obstruction of the ducts with food masses in patients with anastomosis of less than 0,5 cm size, believed by the authors to be critical.

[Hyperbaric oxygenation in the overall therapy of chronic ischemic heart disease].

Seventy-seven patients with chronic ischemic heart disease were treated in single-seater oxygen hyperbaric chambers; 52 patients had angina pectoris of effort or angina of effort and at rest while 25 patients with macrofocal postinfarction cardiosclerosis had insufficiency of pulmonary or systemic circulation. Treatment consisted of 12--15 procedures. The use of hyperbaric oxygenation in a complex with drug therapy makes it possible to alleviate or arrest the attack of angina pectoris and relieve considerably the symptoms of cardiac decompensation. The initial condition of central hemodynamics affects greatly the results of barotherapy. Normal parameters of hemodynamics hardly change after treatment. At the same time, in patients with markedly reduced myocardial contractility hyperbaric oxygenation causes evident positive changes in hemodynamics. The combination of hyperbaric oxygenation with drug therapy improves the effect of treatment significantly.
