The aim of this prospective randomized clinical study was to investigate the role of preoperative carbohydrate admnistration in surgery-induced metabolic, immune and inflammatory reactions after thoracoabdominal operations. At the Surgical department I (B.V. Petrovsky National Research Center of Surgery), we investigated a modulatory role of carbohydrate preload upon surgical stress observed after major thoracoabdominal operations (thoracoscopic and open esophagectomy, retrosternal colonic esophagoplasty) followed by the enhanced recovery protocol. The study was performed in 2014-2017, it included 30 patients, divided into 2 groups. Group A patients (n = 16) received carbohydrates preload (12.5% maltodextrin solution per os or enterally). In patients with dysphagia, the 12.5% dextrose solution was used intravenously in equal volumes. Group B patients didn’t receive any additional preload with carbohydrates. The groups were age- and gender-matched, similar for disease and surgery types. Glucose and insulin levels (with HOMA insulin resistance index, HOMA-IR) were measured before surgery and on day +1, interleukin levels (IL-6, IL-10, IL-8) and index IL-8/IL-10 were assessed before surgery, and on days +1 and +5 after surgery. Cell-mediated immunity was investigated before surgery and on day +5. The stress-induced hyperglycemia (> 7.8 mmol/L) was detected more frequently in group B (50%), than in group A (6%), p = 0.012. Insulin resistance measured by HOMA-IR in group B was detected in 71% of patients and in 25% patients of group A only, p = 0.027. Individual analysis of immune response demonstrated that a trend for immune recovery was detected by the day +5 post-op in the group A. Postoperative levels of IL-6 and IL-10 were lower on day +1 and +5 in group A. Morbidity rates and the terms of hospitalization were similar in both groups. Local postsurgical infections in group A were developed in 6% of the patients vs 35.6% in group B (p = 0.072). In conclusion, a complex study of surgical stress, i.e., metabolic, immune and inflammatory reactions after esophageal surgery has shown that the carbohydrate preload decreased the incidence of postoperative insulin resistance and stress-induced hyperglycemia, being accompanied by lower release of proinflammatory cytokines and provides positive effects upon the patient’s immune system.

AIM: To investigate the role of video-assisted subtotal esophageal resection in treatment of patients with benign esophageal diseases. MATERIAL AND METHODS: Fifty-one patients with benign esophageal diseases have undergone subtotal esophageal resection in our department for the period 2010-2017. Thoracoscopic technique was applied in 25 cases, open approach - in 26 patients. Total surgery time, thoracoscopic stage duration, length of hospital-stay (LOS), ICU-stay, Clavien-Dindo morbidity rates with separate registration of respiratory complications, mortality have been considered. RESULTS: Groups were similar in terms of age, gender, ASA status. Thoracoscopic stage duration gradually decreased from 175 to 65 min with average time of 102 (75; 123) min. Total surgery time was 390 (270; 495) min in group 1 and 465 (341; 561) min in the control group (р=0.035). Mean ICU-stay decreased up to 2 (1.25; 3.75) days compared with the control group (5 (3.92; 5.85) days, р<0.0001). Conversion rate was 8%. In the main group complications Clavien-Dindo grade 2 were detected in 10 (40%) patients compared with 20 (69%) cases in the control group (р=0.009). Respiratory complications occurred in 5 patients in group 1 and in 13 cases of the control group (р=0.039). Mortality was absent. CONCLUSION: Thoracoscopic subtotal esophageal resection may be advisable alternative to open surgery for patients with benign esophageal diseases due to lower postoperative morbidity and earlier rehabilitation followed by improved outcomes.
