[Catheterized balloon mitral valvuloplasty in pregnancy].

Catheterized balloon mitral valvuloplasty was carried out in two females with rheumatic mitral stenosis on the 28th and 24th weeks of pregnancy. The operation on the first patient was performed at the beginning of the development of pulmonary edema. Treatment produced good results in both cases. The surface of the mitral orifice increased from 1.5 and 1.6 to 3.2 and 3.5 cm2, the pressure gradient between the left atrium and left ventricle reduced from 40 and 30 to 6 and 4 mm Hg. There was attended by disappearance of the diastolic murmur and the clinical manifestations of congestion in pulmonary circulation in both patients. Mitral regurgitation did not occur after the operation. Radioscopy lasted 20 and 33 minutes. Protective screens were used to protect the fetus from direct exposure to X-ray. Pregnancy terminated at full term by spontaneous delivery in both patients. The babies, both girls, are healthy. Catheterized balloon mitral valvuloplasty does not yield to closed mitral commissurotomy in efficacy. The mild character of injury inflicted during the operation and no need for general anesthesia make this intervention most preferable in female patients with mitral stenosis during pregnancy.

[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.

[Principles of surgical treatment of inguinal hernia].

The work is based on the analysis of the results of surgical treatment of inguinal hernias in 198 patients in the period from 1983 to 1988. Most of the patients were over 60 years of age, a lesser number were under 35 (11.1%). Hernias of a complicated and transitional form were found in 174 patients and mild forms only in 24 patients. The hernias were recurrent in 45 and sliding in 59 patients. Proceeding from the specific features of the surgical anatomy of the inguinal space, all patients, irrespective of their age and the form and type of the hernia, were treated by operation with plastics of the opening of the hernial sac to the back of the elements of the spermatic cord. The only exception were patients under 35 years of age with a mild form of oblique inguinal hernia, in which case variants of operations with enforcement of the anterior wall of the inguinal canal were carried out. The Schouldies and McVay methods were preferred, in recurrent and all complicated forms of inguinal hernias they were combined with operations of the Endrews and Postempsky types; the last named was mostly used in individuals over 60 years of age and in repeatedly recurring hernias. The late-term results were studied in follow-up periods of 2 to 7 years in 176 patients in the group of 198 individuals who were operated on. In 77.7% of them 3-6 years have passed since the operation. Almost all patients of mature age have resumed their occupation, there are complaints neither of pain at the site of the operation nor of changes in sexual potency. Recurrent hernias were not detected.

[Characteristics of wound infection in long-term crush syndrome].

Clinicobacteriological examination was carried out in 31 patients with the crush syndrome (CS) and extensive damage to the soft tissues in combination with bone fractures complicated by wound infection. Inadequate surgical treatment in the early periods after the trauma (complete closure of the wound, making small incisions of the involved skin and subcutaneous fat) is particularly hazardous in such cases because it leads to the development of severe wound infection. This disease is marked by a complex polymicrobial structure of the causative agents, massive dissemination of aerobic and opportunistic anaerobic bacteria in the purulent focus (10(7)-10(9) microbial bodies), and a high proportion (48.4%) of obligate anaerobic microflora. Wound infection in the CS takes a grave clinical course, but without profound microbiological study it is difficult to differentiate it into aerobic and anaerobic (clostridial and ++non-clostridial) forms. This is evidence of the need for emergency extended bacteriological diagnosis at all the stages of treatment. "Pure" aerobic infection was identified in half of the patients and mixed aerobic-anaerobic infection in the other half. The possibility of the involvement of asporogenic anaerobes is shown (35.5% of cases). The high risk of the development of gas gangrene is detected (9.7%) and its is concluded that early prevention is necessary by adequate surgical intervention, adequate intensive antibacterial and detoxification therapy, including hyperbaric therapy. The efficacy of current antigangrene immunization agents must be evaluated.

[Use of 25-MeV brehmsstrahlung in the combined treatment of cancer of the large intestine].

Preoperatively, 105 patients with cancer of the colon were subjected to radiation therapy with a braking beam from 25 MeV Betatron. The colon was examined roentgeno-endoscopically in all these cases. As a result of the radiation treatment a marked clinical effect was noted in 94 patients, while in 12 cases locally-unresectable tumors were rendered resectable. 77 patients were radically operated upon, and a morphological assay of the operation specimens indicated significant changes arising in the tumor tissue due to the effect of ionizing radiation. The results of the combined therapy of colonic cancer patients prove the rationale of employing high-energy radiation therapy preoperatively.

[Multiple primary stomach tumors].

The observations over 15 cases of primary multiple stomach tumors (1.93% of cases of stomach cancer) are presented in the article. The synchronous tumors were diagnosed in 5 patients, the metachronous ones--in 10. As a rule, the synchronous lesion of the stomach is recognized at the operation or at histological study of ablaed stomach. In metachronous evolution of tumors cancer of the stomach stump was found within the follow-up period--from 2 to 26 years. To choose the volume of a surgical intervention for cancer of the stomach, it is expedient to carry out the biopsy of the mucous membrane from various sites during gastroscopy. The patients, operated upon for cancer of the stomach, need an active follow-up without time limitation.
