[Intraductal radiofrequency ablation for neoplasms of the major duodenal papilla with intraductal spread]. / Vnutriprotokovaya radiochastotnaya ablyatsiya pri novoobrazovaniyakh bol'shogo sosochka dvenadtsatiperstnoi kishki s vnutriprotokovym rasprostraneniem.

OBJECTIVE: To analyze the efficacy of intraductal radiofrequency ablation (RFA) for neoplasms of the major duodenal papilla with intraductal spread. MATERIAL AND METHODS: Eleven patients with adenomas of the major duodenal papilla and intraductal spread underwent intraductal RFA between 2022 and 2023. Spread to the common bile duct ranged from 10 to 30 mm, to the main pancreatic duct - from 5 to 11 mm. RESULTS: Technical success was achieved in all cases. Complications after intraductal RFA occurred in 4 cases (post-manipulation pancreatitis - 2 cases, repeated intraductal RFA for residual adenomatous growths - 2 cases). Technical success of stenting of the main pancreatic and common bile ducts was achieved in all cases. CONCLUSION: Intraductal radiofrequency ablation for neoplasms of the major duodenal papilla with intraductal spread ensured complete destruction of intraductal tumor with adequate clinical effect and no need for highly traumatic surgery.

[Endoscopic treatment of esophageal anastomotic leakage using vacuum-assisted closure system]. / Éndoskopicheskoe lechenie nesostoiatel'nosti pishchevodnykh anastomozov s ispol'zovaniem vakuumno-aspiratsionnoi sistemy.

OBJECTIVE: To analyze the effectiveness of vacuum-assisted closure system for esophageal anastomotic leakage. MATERIAL AND METHODS: There were 10 patients with upper gastrointestinal anastomotic leakage who were treated at our institution in 2015-2018. Vacuum aspiration system was applied in all cases. RESULTS: Esophageal wall defect was successfully closed in 9 out of 10 patients after 2-4 courses and the system was eliminated in 11 days on the average. Localized cavity with granulation tissue developed in 1 patient after 5 courses and the system was also eliminated. CONCLUSION: Endoscopic vacuum-assisted therapy is an innovative, minimally invasive, economically profitable and successful method for anastomotic leakage. This procedure should be taken into consideration and widely used in multi-field hospitals.
