Compression Hemostasis in Refractory Esophageal Bleeding

Abstract

RELEVANCE. Efficiency and safety of compression hemostasis with esophageal self-expanding nitinol stents Danis compared to the Sengstaken–Blakemore tube in the treatment program of refractory esophageal bleeding still remains a controversial issue. AIM OF THE STUDY. To conduct a comparative analysis of the effectiveness of Danis self-expanding compression hemostasis nitinol stent and the Sengstaken-Blakemore tube for variceal esophageal bleeding refractory to drug and endoscopic treatment. MATERIAL AND METHODS. The first comparison group included 44 patients, in whose complex treatment program tamponade with a Sengstaken-Blakemore tube was used to save lives. The second main group of the study consisted of 15 patients in whom compression hemostasis was performed using Danis self-expanding nitinol stent. Statistical processing was carried out using the Kolmogorov-Smirnov, Student, χ2 and Fisher exact tests. Differences were considered statistically significant at p ≤ 0.05. RESULTS. In the comparison group, complications occurred in 44 (100 %), in the main group complications were observed in 8 patients (53.3 %). Accordingly, reliable mechanical hemostasis was achieved in 33 (75.0 %) and 13 clinical observations (86.7 %); trophic changes in the esophageal mucosa were detected in 12 (27.2 %) and 8 patients (53.3 %). When assessing the function of external respiration, 5th and 2nd degrees of decrease in the ventilation capacity of the lungs, as well as 3rd and 1st degrees of decrease in the vital capacity of the lungs were established. The overall mortality was 56.8 % in the comparison group and 26.7 % in the main group. CONCLUSION. Self-expanding compression hemostasis nitinol stent Danis as a bridge to the choice of definitive therapy compared to tamponade with the Sengstaken–Blakemore tube is a promising alternative first-line treatment for patients with refractory esophageal bleeding. At the same time, it is necessary to conduct randomized controlled studies to confirm the safety and effectiveness of self-expanding nitinol stents.
