[One thousand endoscopic submucosal dissections. Experience of the national center].

Background: Endoscopic submucosal dissection (ESD) is a perspective method of organ-sparing treatment of benign colon tumors.

Material And Methods: The study included 1.000 patients with colon neoplasms who underwent ESD between October 2016 and October 2021.

Results of total mesorectal excision and transanal endoscopic microsurgery for rectal adenocarcinoma with submucosal invasion.

Objective: To analyze early and long-term outcomes after total mesorectal excision (TME) and transanal endoscopic microsurgery (TEM) in patients with T1 rectal cancer.

Material And Methods: A retrospective non-randomized comparative study included 2 groups of patients: group 1 - total mesorectal excision, group 2 - transanal endoscopic microsurgery. In the second group, total mesorectal excision was proposed for patients with tumor invasion depth pT1sm3 and/or lymphovascular invasion and/or low differentiation.

Endoscopic submucosal dissection versus endoscopic mucosal resection for colorectal tumors: a systematic review and meta-analysis.

Objective: To compare early (resection quality, complication rate, surgery time) and long-term (recurrence rate) outcomes of endoscopic submucosal dissection versus endoscopic mucosal resection.

Material And Methods: A systematic review and meta-analysis was performed in accordance with the PRISMA guidelines. Data were analyzed using the Rewiew Manager 5.

[Surgical treatment of rectovaginal fistula with vaginal rectangular flap].

Objective: To evaluate the early and long-term outcomes of rectovaginal fistula closure with vaginal rectangular flap.

Material And Methods: There were 61 patients with rectovaginal fistula for the period 2012-2020. Median age of patients was 35 years [31; 48].

Comparison of oncological and functional outcomes and quality of life after transanal or laparoscopic total mesorectal excision for rectal cancer: a systematic review and meta-analysis.

Background: The aim of this study was to compare long-term oncological, functional outcomes and quality of life (QoL) after transanal total mesorectal excision (TaTME) and laparoscopic total mesorectal excision (LaTME) for rectal cancer.

Methods: A systematic review and meta-analysis based on Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were conducted on PubMed and Cochrane database. Non-randomized controlled trials (NRCTs) which compared TaTME with LaTME were included.
