[Modern methods of treatment of inguinal hernias].

Surgical methods of treatment have been analyzed with special reference to wide introduction of new technologies. Altogether there were 4424 operations for inguinal hernias. Traditional plasty of the posterior wall of the inguinal canal with autotissues was used in 2136 patients. Lichtenstein operations were fulfilled on 521 patients, laparoscopic transabdominal preperitoneal hernioplasty--on 1614, complete preperitoneal hernioplasty--on 153 patients. The analysis made has shown that an introduction of modern surgical technologies into clinical practice allowed reduction of the percentage of complications and recurrences. The share of operations by the "tension-free," method was as high as 52%.

[Resection with pyloric retention as a method for prophylaxis of dumping syndrome].

The aim of the study was the evaluation of efficacy of the resection with pyloric retention proposed by the authors as a method for prevention of post gastroresectional damping syndrome in patients with ulcers. Resection with pyloric retention is performed in six modifications of three basic methods of resections. We have the experience of using this approach in 712 clinical cases. Among them 237 were women and 475 were men 19-75 years of age. It was shown that resection with pyloric retention provides rhythmic evacuation and prevents development of damping syndrome and duodenal reflux. It was found that the main reasons of the development of postgastroresectional syndromes include wide-area mobilization of the stomach and resection of the small curvature, which induce insufficiency of cardia, atony, chronic disturbances of the duodenal passing. Due to the retention of pyloric function damping syndrome have been developed only in 3 patients. In all these cases the syndrome was mild. It may be concluded that gastric resection with pyloric retention represents the most "physiological" intervention and has many advantages in comparison with other methods.

[Prospects for video-endoscopic surgical technique in incarcerated hernias].

An analysis of generalized clinical material includes 60 diagnostic laparoscopies performed in patients with incarcerated hernias and 48 curative endovideosurgical interventions in patients with incarcerated inguinal and femoral hernias. Attention is called to the extension of technological resources of the operative treatment of incarcerated hernias using the laparoscopic technique and possible transformations of the operative strategy in such cases.

[Intraoperative ultrasonic scanning of extrahepatic bile ducts].

The intraoperative ultrasonic investigation (IOUSI) of bile tracts was used during laparoscopic cholecystectomy for chronic (53 patients) and acute (25 patients) calculous cholecystitis and during 74 open operations in patients with mechanical jaundice. In half of the cases IOUSI was combined with intraoperative cholangiography (IOCG). A conclusion made on the basis of the clinical material suggests that IOUSI allows better assessment than IOCG of the state of the bile duct walls and pancreas head, the consistency of the duct content and can detect small (2-5 mm) concrements more exactly. However IOCG is more effective in determining the function of the bile tracts. So, the methods are thought to be not competing but mutually supplementing.

[Original nitinol monowire stent for percutaneous iliac arterial reconstructions].

Nitinol monowire stents of original construction were implanted to 35 patients (aged from 36 to 84, mean 53.9) with atherosclerotic lesions of iliac arteries. Arterial stenosis ranged from 50% to 100% (mean 72.2%), ankle-brachial index (ABI) averaged 0.45+/-0.12. Initial success was achieved in 97.1% of procedures. Ultrasonography 3 days since the procedure showed the increase of ABI up to 0.78+/-0.16. Restenoses in the stented site was revealed during follow-up period (mean 24.3+/-18.3 months) in 3 patients (8.3%). In conclusion, new stent appeared to be effective tool for treatment of iliac atherosclerotic lesions. However long-term restenoses resulting from intimal hyperplasia can require repetitive revascularization.

[The endoscopic ligation and sclerotherapy in a complex prevention program of variceal bleedings in extrahepatic portal hypertension].

The results of prophylactic endoscopic treatment of 22 patients with extrahepatic portal hypertension (main group--EPH) and 76 patients with cirrhosis of the liver (a comparison group--CL) who had had variceal bleedings were analyzed. In the EPH group permanent eradication was obtained in 14 patients (63.6%), in the CL group--in 46 patients (50.5%). With the average duration of achieving the eradication the number of sessions before achieving it proved to be greater than that for CL. Recurrent bleeding during the first month of observations was noted in 7 out of 22 patients. In most cases the sources of bleedings were postligational and postinjectional ulcers of the cardial part of the stomach. Long-term results (1-5 years) were followed-up in 14 patients. In 9 patients there was no recurrent bleeding during 2-5 years of observation. Thus, it is expedient to use endoscopic interventions as the methods of the "first line" in the complex program of secondary prophylactics of variceal bleedings in extrahepatic portal hypertension.

[Prophylactics and treatment of pyo-inflammatory complications after appendectomy].

The developed method of prophylactics and treatment of pyo-inflammatory complications in the wound after operation of appendectomy with the help of mid-frequency ultrasound with dioxidin as phonophoresis allows to make suppurations in the postoperative patients 5.15 times rarer and the number of pyo-inflammatory complications 6.68 times rarer. The time of healing the wounds was 1.2+/-0.3 days shorter and the duration of treatment of such patients in the hospital 1.8+/-0.8 days less.

[A comparative analysis of results of treatment of patients with acute varicose esophago-gastric bleeding: the role of endoscopic technologies].

The aim of the work was to make a comparative analysis of results of treatment of patients with varicose esophago-gastric bleeding depending on using the endoscopic technologies--ligation and sclerotherapy. The investigation included 161 patients. The main group consisted of 65 patients treated with using the endoscopic technologies--ligation and sclerotherapy due to emergency indications. The comparison group included 96 patients given conservative treatment with the application of Blackmoor probe. The endoscopic methods of surgery allowed to get arrest of bleeding reliably more often (92.3 vs 67.7%, p < 0.05). The number of patients having recurrent bleedings in the main group was 2.7 times less, the intrahospital lethality--3.4 times less than in the group of comparison (p < 0.05).

[Surgical treatment in chronic gastroduodenal ulcers].

Operative treatment was carried out in 1197 patients with chronic gastroduodenal ulcers. Among the most frequent complications of the ulcers there were penetration of the III-IV degree, compensated, subcompensated and decompensated pyloroduodenal stenosis. The operative interventions included Billroth-II resections of the stomach in modification of Hofmeister-Finsterer, Billroth-I, with saving the pyloric sphincter, after Roux and gastrectomies. Postoperative complications developed in 127 (10.6%) patients, postoperative lethality was 0.7%. Excellent and good long-term results were noted in 846 (94.5%) patients, in 14 (1.6%) patients they were estimated as satisfactory and in 35 (3.9%) as unsatisfactory. The causes of unsatisfactory results were recurrent ulcers (0.7%), peptic ulcer of the gastroenteroanastomosis (0.6%), dumping-syndrome of a severe and medium degree (1.5%), diarrhea of a severe degree (0.3%) and erosive-ulcerous reflux-esophagitis (0.3%).

[Endovascular intrahepatic portacaval shunting].

Pilot experience in Russia of transjugular intrahepatic portosystemic shunting is presented. Results of endovascular shunting in 14 patients with cirrhosis of the liver were analyzed. Four patients underwent emergency endovascular shunting when conservative treatment was not effective. Ten patients underwent elective surgery. Repeated esophagealgastric bleedings were indications for shunting. Relapse of bleeding was seen in 1 patient 5 days after surgery. Regular dopplerography permitted to reveal timely stenotic process. When stenosis of portosystemic shunt was diagnosed, ambulatory balloon dilatation of anastomosis through transjugular approach was performed. It was enough for opening of anastomosis lumen and decrease of pressure gradient.

[Evaluation of the effectiveness of Dopplerography in patients with diffuse liver disease with portal hypertension syndrome].

Under analysis were the results of Dopplerography of the abdominal cavity vessels in 66 patients with liver cirrhosis and 14 patients with the extrahepatic portal block. The sensitivity of the method in diagnostics of the intrahepatic block was 96.9%. The linear rate of the blood flow along the upper mesenterial vein was the most sensitive dopplerographic criterion of liver cirrhosis with the portal hypertension syndrome, the most specific test was the determination of the hepatic artery pulsativity index. A considerable decrease of the index of linear and volume rates of blood flow along the splenic vein and higher index of the splenic artery pulsativity were observed when the functional reserves of the liver decreased. A higher resistance index and the presence of the III degree gastroesophageal anastomoses are characteristic of the patients with bleedings from the veins of the esophagus and stomach.

[Endoscopic sclerotherapy and ligation of varicose veins of the esophagus and cardia].

Results of endoscopic treatment of 39 patients with acute bleeding from varicose veins of the esophagus and cardia and of 46 patients as prophylaxis of bleeding recurrence are presented. Rate of primary hemostasis in acute bleeding was 92.3%. In 3 patients with bleeding from varicose veins of cardia endoscopic treatment was not effective. In prophylactic treatment rate of bleeding recurrence during 1 year was 15.2%. A 6 month--survival was 93.3%, it depended on functional group by Child. Endoscopic methods (sclerotherapy, ligation) are effective for arrest and prophylaxis of portal bleedings.

[Endoscopic methods of prevention and treatment of hemorrhage of portal genesis].

Results of endoscopic interventions on 72 patients with portal hypertension of different etiology are presented. In patients with acute bleedings the frequency of primary hemostasis was 94%. In 2 patients with hemorrhages from the cardial veins of the stomach the endoscopic interventions proved to be ineffective. Prophylactic treatment gave 20% recurrent bleedings during a year. Survival of the patients during 6 months was 88.5% and considerably depended on the functional group according to Child. The endoscopic interventions (sclerotherapy, ligation) should be considered effective methods to arrest bleeding and to prevent bleedings of portal genesis.

[Surgical strategy in liver hemangiomas].

The authors made an analysis of results of surgical treatment of 129 patients with hepatic hemangiomas and of the 9-year follow-up of these patients. The dynamic care of these patients is recommended in cases of 5 cm diameter hemangiomas and the absence of clinical symptoms. The surgical treatment was necessary but in 10% of such patients. In the majority of such patients embolisation of the hepatic artery is expedient if surgical treatment is necessary. Indications for resection of the liver are restricted.
