The article presents an analysis of 34.903 esophagoscopy results performed for population of Leningrad region at the period from 2007 to 2013. A prevalence of erosive esophagitis was 4.9%, peptic strictures--0.18%, columnar-celled metaplasias--1.43% and esophageal adenocarcinoma--0.645%. The data obtained showed a high prevalence of GERD-associated syndromes with injury of mucous coat of esophagus in the local population of Russians.

An investigation included 33 patients with cancer of thoracal section of the esophagus at the age from 42 to 74 years old. A surgical method of treatment was applied as only one in 13 patients and methods of nonadjuvant chemoradiation therapy were used for 20 patients. A hybrid minimally invasive esophagectomy (laparoscopic mobilization of the stomach and right-side thoracotomy) was performed on 16 patients. The rate of postoperative complications consisted of 31%. The minimally invasive esophagectomy (performed by totally endovideosurgical approach) was carried out in 15 cases. Postoperative complications developed in 53% of follow-up patients. There weren't cases of lethality. The experience of minimally invasive methods indicated the satisfactory results of application of given methods in patient treatment of esophageal cancer. The use of endovideosurgical approaches allowed performing oncologically adequate volume of operative interventions.

For treatment of cancer of the thoracic esophagus, the method of neoadjuvant chemoradiotherapy (CRT) with a use of intraluminal brachytherapy (BT) was performed. The study included 51 patients (mean age 56.9 ± 4.3 years). The length of the primary tumor up to 6 cm was determined in 18 patients, more than 6 cm--33 patients. CRT included three BT sessions (7Gy X 3; q7d) and two cycles of chemotherapy (PF; q28d). After CRT in 30 (62.4%) patients there was marked a complete or partial radiological tumor regression. In 40-45 days after CRT surgery performed. Subtotal resection of esophagus of the Lewis type was performed in 29 cases, transtracheal ex- tirpation of the esophagus--in 2, minimally invasive esopha- gectomy--in 17 cases. Postoperative complications occurred in 22 (44%) patients; one patient died (2%). In 11 (23%) patients morphological investigation revealed a complete regression of the primary tumor. Thus, a use of intraluminal BT in combination with chemotherapy in many cases promoted reducing the size of the primary tumor of the esophagus, which was an effective factor in improving surgical results.

The locally advanced cancer of thoracic esophagus was treated by induction chemo-irradiation therapy (IHRT) with intraluminal medium dose-rate brachytherapy (IMBT). From July 2009 to February 2012 twenty five patients (mean age 54.3 +/- 1.3 years) were included in the study. The length of the primary tumor was up to 6 cm in 10 pts and more than 6 cm in 15 pts. Induction therapy consisted of three IMBT sessions (7 Gy X 3; q7d) and two cycles of chemotherapy (PF; q28d), 26-31 days later the surgery was performed. Subtotal resection of the esophagus type of I Lewis was performed in 23 pts, transtracheal extirpation of the esophagus was performed in 2 pts.In all the cases 3F lymphodissection was performed. After IHRT in 15 of 25 pts. was obtained complete or partial response, in 10 of 25 pts was obtained disease stabilization. Perioperative complications occurred in 17 (68%) patients receiving conservative treatment, one patient (4%) died of treatment complications. In 6 cases (24%) morphology had shown the complete regression of primary tumor. Thus, the combination of intraluminal medium dose-rate brachytherapy and chemotherapy lead to reduction of primary tumor local spread and can be an efficient factor in improving the results of surgical treatment.

It was evaluated mini-invasive endovideosurgical technologies using in complex treatment of esophagus cancer. The investigation included 28 patients with thoracic esophagus cancer. Age of patients operated in terms from April 2012 to December 2013 was from 42 to 74 years (mean 61.7 ± 8.7 years). Only surgical treatment was used in 10 patients. Neoadjuvant chemotherapy and radiotherapy were performed in 18 patients. Hybrid mini-invasive esophagectomy (laparoscopic stomach mobilization and right-side thoracotomy) were used in 14 cases. The frequency of postoperative complications was 35.5%. Mini-invasive endovideosurgical esophagectomy was done in 14 patients. The frequency of postoperative complications was 57.1%. There were not deaths. Our experience demonstrates good results of mini-invasive technologies using in treatment of patients with esophagus cancer. Endovideosurgical methods permit to perform adequate volume of surgery in case of oncological diseases.Оценена возможность использования минимально инвазивных эндовидеохирургических технологий в комплексном лечении рака пищевода. В исследование включены 28 больных раком грудного отдела пищевода, оперированных с апреля 2012 по декабрь 2013 г. Возраст больных от 42 до 74 лет (в среднем 61,7±8,7 года). Только хирургический метод лечения был применен у 10 больных. Неоадъювантная химиолучевая терапия проведена 18 больным. Гибридная минимально инвазивная эзофагэктомия (лапароскопическая мобилизация желудка + правосторонняя торакотомия) выполнена 14 больным. Частота послеоперационных осложнений составила 35,5%. Минимально инвазивная эзофагэктомия (полностью эндовидеохирургическим методом) произведена 14 больным. Послеоперационные осложнения развились в 57,1% наблюдений. Летальных исходов не было. Опыт использования минимально инвазивных технологий в лечении больных раком пищевода свидетельствует об удовлетворительных результатах применения таких методик. Использование эндовидеохирургических методов позволяет выполнять онкологически адекватный объем оперативных вмешательств.
