[Gastrointestinal bleeding in acute intoxications with non-cauterizing chemicals].

The results of esophagogastroscopy in patients with gastro-intestinal bleeding caused by acute intoxication with noncauterizing chemicals are available. Gastro-intestinal bleeding was detected in 96 of 142 patients. Mallory-Weiss syndrome was detected in 45 patients (46.9%), erosions of mucosa of esophagus and stomach--in 27 (28.1%), traumatic lesions of mucosa--24 (25.0%). The curative endoscopic intervention aimed to stop the bleeding and prevent its recurrence was performed in 31 patients.

[Healing of extensive acute gastric ulcer after chemical burn by Helium-Neon laser (endoscopic and morphologic investigation)].

The paper provides the results of endoscopic and morphologic follow-up of healing of extensive corrosive gastric ulcer in He-Ne laser therapy of 34 patients (512 gastric biopsies). Laser radiation of ulcer reduces frequency of stenosis in healing outcome as well as treatment duration, creates conditions for healing without leukocytic fusion of necrotic tissues. Effectivity of laser therapy is determined by the time of its start and regularity.

[Evaluation of various methods of treatment in chemical burns of the stomach using fiber endoscopy].

Results of conservative measures alone and in combination with local exposure of the burn to laser radiation or clue applications have been compared for 95 patients with chemical burns in the stomach. The combined therapy proved more beneficial as it provided more active healing of the wound, less frequent stenotic complications, shorter hospital stay. Earlier start of local treatment using fiber endoscopy is recommended.

[Rethoracotomies and repeat operations on the lungs].

The article generalizes materials of 148 rethoracotomies. Main complications are described. Grounds are given for the use of perfusion through the xenospleen at the early postoperative period in order to liquidate the coagulated haemothorax mainly after pulmonectomy. An original method of determination of the coefficient of relative viscosity of the exudate on the absorbing base is described. The method allows the objective control of infectivity of the pleural exudate to be performed. The clinical use of different methods of detoxication in the preoperative period is substantiated: UVI of blood, hemocarbosorption and xenohemosorption, which allowed to reduce lethality after rethoracotomies and reoperations on the lungs.

[Endoscopic biopotential measurement in the diagnosis of the degree of esophageal mucosal involvement in chemical burns].

Results of examination of 43 patients with injuries of the esophagus by cauterizing substances were obtained using the method of endoscopic biopotentialometry. It was shown that the method of endoscopic biopotentialometry is simple, allows rapid and exact determination of the degree of the injury of gastric mucosa at early terms from the moment of burn, choice of correct methods of treatment and prevention of such serious complications as bleedings, strictures etc.

[Course of wound process in chemical burns of the stomach (results of morphological and endoscopic studies)].

The dynamics of the wound process in chemical burns of the stomach were studied on the basis of histological and endoscopic examinations. The patients who were studied were given nonoperative treatment, in all cases for corrosive gastric ulcers. The most frequent complications were cicatricial stenoses (86.6%) in involvement of the antral part of the stomach. Regeneration of the damaged tissues of the gastric wall was disturbed, the specific features of these disorders were studied.

[Prevention of complications of endoscopic electric excision of benign tumors of the stomach].

The authors suggest a method for endoscopic infiltration of glue under the base of a benign gastric tumor before its removal through an endoscope, for the prevention of bleeding from its seat and perforation of the organ. The method was used in removal of 116 benign tumors measuring from 0.5 to 5.0 cm in size. The results provide evidence of reliable prevention of these complications with the use of the suggested method.

[Esophagogastroduodenoscopic indices in patients with calculous cholecystitis].

It is concluded on the basis of probability analysis about the necessity of including esophagogastroduodenoscopy in the complex of preoperative examination of patients with calculous cholecystitis. Data of 1050 consecutive esophagogastroduodenoscopies for calculous cholecystitis confirm from clinical positions the expediency of the mathematically based tactics.

[The use of copper-vapor laser radiation on patients with chemical burns of the esophagus via fiber esophagoscopy].

Fifty patients with chemical burns of the esophagus were examined fibroesophagoscopically. All of them underwent local endoscopic irradiation by a copper vapour laser. Laser treatment promoted more rapid healing of the esophageal wall. No cicatrization-induced strictures were noted. Adjuvant local laser therapy is believed valid in management of esophageal chemical trauma.

[The local treatment of chemical burns of the esophagus via an endoscope by means of laser therapy and adhesive application].

An examination of 180 patients with chemical burns of the esophagus was performed. Local endoscopic treatment with the help of low energy laser irradiation and glue applications was used in 120 patients. Preference is given to the method of local laser therapy because of the best results of treatment and the absence of risk of putting out of order the expensive apparatus resulting from an ingress of glue on it.

[Fungal infection of the esophagus and stomach after chemical burns].

Endoscopic signs of esophageal fungal lesions were established in 7.5% of patients with chemical impairment of the gastrointestinal tract on day 10-15 since the burn. Endoscopically, there were two forms of the esophageal lesion. To make the diagnosis more reliable, specific evidence at endoscopy and bacterioscopy should be used while the differential diagnosis should be based on biopotentialometry. Early diagnosis of fungal involvement may provide better response in the treatment of patients with chemical burns.
