[Emergency surgery under Covid-19 pandemic and its influence on postoperative outcomes]. / Ekstrennaya khirurgiya v usloviyakh pandemii Covid-19 i ee vliyanie na iskhody khirurgicheskogo lecheniya.

OBJECTIVE: To analyze the effectiveness of emergency surgical care under COVID-19 pandemic and its impact on postoperative outcomes. MATERIAL AND METHODS: We analyzed the results of treatment of 1.749 patients who were treated from May 01 to September 30 in 2018-2020. The study group consisted of 48 COVID-19 patients with urgent surgical diseases. The control group consisted of patients with emergency surgical diseases and no coronavirus infection. RESULTS: The new coronavirus infection significantly increases in-hospital mortality by 8 times and postoperative mortality by 6.5 times compared to pre-pandemic period. CONCLUSION: Emergency surgical care to COVID-19 patients is accompanied by increase of in-hospital mortality up to 31.3% and postoperative mortality up to 33.3%.

[Pancreatic duct stenting in the treatment of acute pancreatitis]. / Vliyanie stentirovaniya glavnogo pankreaticheskogo protoka na rezul'taty lecheniya bol'nykh s ostrym pankreatitom.

OBJECTIVE: To study the effect of pancreatic duct stenting on the results of treatment of acute pancreatitis. MATERIAL AND METHODS: Analysis included 99 patients with acute pancreatitis. Endoscopic stentingwas appliedin the study group, conventional approach - in the control group. RESULTS: Pancreatic duct stenting at theearly stages ofacute pancreatitis results decreased level of enzyme toxemia and manifestations of systemic inflammatory response. CONCLUSION: Stenting interrupts course of pathological process and minimizes the possibility of transition of aseptic to infected pancreatic necrosis. Therefore, reduced early mortalityis observed.

[Clinical evaluation of endoscopic hemostasis in patients with ulcerative gastroduodenal bleeding]. / Klinicheskaia otsenka éndoskopicheskii gemostaz v lechenii bol'nykh s gastroduodenal'nym krovotecheniem iazvennoi étiologii.

AIM: To compare the effectiveness of various methods of endoscopic hemostasis in patients with ulcerative gastroduodenal bleeding. MATERIAL AND METHODS: Several surgical techniques in treatment of 117 patients with ulcerative gastroduodenal bleeding were anayzed. Isolated and combined methods of endoscopic hemostasis were used in control and study groups. RESULTS: Combined endoscopic hemostasis is bettercompared with isolated techniques. It reduces the incidence of recurrence, surgical activity and mortality. CONCLUSION: The effectiveness of combined endoscopic hemostasis was 88.2% for primary hemostasis in acute ulcerative gastroduodenal bleeding. Herewith, surgical activity and mortality were decreased.
