[Preoperative predictors of obesity recurrence after laparoscopic gastrectomy]. / Predoperatsionnye prediktory retsidiva ozhireniya posle laparoskopicheskoi prodol'noi rezektsii zheludka.

OBJECTIVE: To find the preoperative predictors of obesity recurrence. MATERIAL AND METHODS: We analyzed 81 patients with obesity who underwent laparoscopic sleeve gastrectomy. Patients were followed-up for 5 years and divided into 2 groups (64 (79.0%) patients were in the persistent weight loss group and 17 (21.0%) ones were in the obesity recurrence group). RESULTS: We tried to make a mathematical model for predicting obesity recurrence after bariatric surgery based on various parameters (age, height, weight, hemoglobin A1C, lipoprotein A, T3, T4, triglycerides, TSH, cholesterol, arterial hypertension, diabetes, metabolic syndrome, percentage of fat mass). We trained the following classification models: logistic regression, naive Bayes classifier, decision tree. None classifier provided sufficient prediction quality. This may indicate that these data do not allow predicting of obesity recurrence after sleeve gastrectomy. CONCLUSION: We failed to construct a mathematical model based on preoperative data of patients with obesity predicting recurrence in long-term period after sleeve gastrectomy.

[Comparative analysis of immediate results of surgery for colon cancer using laparoscopic and robot-assisted surgical interventions].

In recent decades there has been achieved significant progress in treatment for colorectal cancer. Minimally invasive surgery (including robot-assisted) is rapidly gaining widespread acceptance in treatment of this form of cancer. Today robotic surgery is a revolutionary technology that opens a new stage in the development of surgery of the 21st century. Currently in the world there have been performed more than 2 million surgical interventions of the colon using a robotic surgical complex Da Vinci. To date it was accumulated a large number of single-center studies comparing laparoscopic and robot-assisted interventions in cancer of various parts of the colon for short-term and long-term treatment outcomes, which showed their effectiveness and safety. Modern colorectal surgery could not be imagined without the latest technology, the use of which directly affects the quality of life of patients after surgery.

[100 ROBOTIC-ASSISTED OPERATIONS IN COLORECTAL CANCER (FIRST OUTCOMES)].

This article analyzed the immediate treatment results of 210 patients, underwent endovideosurgical operative treatment concerning colorectal cancer (106 laparoscopic and 104 robotic-assisted operations). According to the first results, there was no significant difference between two methods in such medical indices as the volume of intraoperative hemorrhage, terms of hospital stay and peristalsis recovery, the rate of conversion and complications in. early postoperative period, quantity of removed lymph nodes, quality of TME. The application of robotics allowed performance of precision work in conditions of limited space of the small pelvis.
