[Reversal of Hartmann's procedure in patients with diverticular disease]. / Rekonstruktivno-vosstanovitel'nye vmeshatel'stva posle operatsii Gartmana u patsientov s divertikulyarnoi bolezn'yu.

OBJECTIVE: To analyze intraoperative and early postoperative results of open and laparoscopic reversal of Hartmann's (HR) procedure in patients with diverticular disease. MATERIAL AND METHODS: A single-center retrospective non-randomized study included 31 patients with complicated form of diverticular disease between 2018 and 2022. Patients underwent reversal of Hartmann's procedure (laparoscopic surgery - 19, laparotomy - 12). RESULTS: Mean time of laparoscopy and open surgery was 202±36.7 and 223±41 min, respectively. There were no intraoperative complications in both groups and conversions of laparoscopic reversal of Hartmann's procedure. No preventive stoma was required. Mean postoperative hospital-stay was 7.6±3.2 and 9.5±4.6 days, respectively. Overall incidence of postoperative complications was 32.2% (n=10), i.e. 4 (21%) and 6 (50%) patients in both groups, respectively. Anastomotic leakage occurred in one patient after open surgery. CONCLUSION: In our sample, incidence of complications was low after reversal of Hartmann's procedure in patients with complicated diverticular disease. There was 1 (3.2%) patient with anastomotic leakage, and no temporary stoma was formed. In patients who underwent laparoscopic Hartmann's procedure at the first stage and selected patients after open surgeries, laparoscopic reversal procedures were accompanied by no conversions. There were favorable results typical for minimally invasive surgery. Selection criteria for laparoscopic access are discussable. Large-scale studies including randomized trials are needed to verify selection criteria for minimally invasive reversal of Hartmann's procedure and demonstrate its advantages over open surgery.

[The results of colorectal resection for bowel deep infiltrating endometriosis]. / Osobennosti kolorektal'nykh rezektsii pri glubokom infil'trativnom endometrioze.

OBJECTIVE: To study the early postoperative outcomes of segmental bowel resections in patients with colorectal endometriosis. MATERIAL AND METHODS: A retrospective study included 60 patients diagnosed with deep infiltrative endometriosis who underwent surgical treatment with segmental bowel resection between 2016 and 2022. RESULTS: All surgeries performed by two teams (gynecologic & colorectal). 59 operations were performed by laparoscopic access and one open. The average operation time was 263.5±86.0 min, estimated blood loss 126.1 ml (10-400 ml). There were no intraoperative complications. There were no conversions during laparoscopic surgery. A protective stoma was not required in any patient. The median postoperative hospital stay was 7.5±4.2 days. Bowel function was restored by an average of 4.3±3.1 days. Postoperative complications were in 7 cases (11.6%). Anastomotic leakage occurred in one patient (1.6%). The incidence of urine retention requiring repeated bladder catheterization was 2 (3.3%). CONCLUSION: The use of a minimally invasive multidisciplinary approach makes it possible to perform the required volume of surgery with excision of all tissues affected by endometriosis with a low level of complications and the absence of conversions.

[Features and results of minimally invasive treatment of recurrent achalasia]. / Osobennosti i rezul'taty maloinvazivnogo lecheniya retsidiva akhalazii kardii.

OBJECTIVE: To evaluate the early and long-term postoperative outcomes in patients with recurrent achalasia, as well as the main features of surgical treatment. MATERIAL AND METHODS: There were 7 patients (4 men and 3 women) with recurrent achalasia. Mean age of patients was 42.3±13.5 years, body mass index - 22.7±3.3 kg/m2. Physiological status ASA grade 1-3 was observed in all patients. Concomitant diseases were diagnosed in 5 (71.4%) cases. Six (85.7%) patients underwent laparoscopic Heller cardiomyotomy with Dor fundoplication. Peroral endoscopic myotomy (POEM) was performed in 1 (14.3%) patient. Mean preoperative Eckardt score was 10.7±1.4 points, mean GERD-HRQL score - 42.7±6.4 points. According to preoperative radiography, 5 (71.4%) patients had achalasia stage III, 2 (28.6%) ones - stage IV. RESULTS: All patients underwent laparoscopic Heller esophagocardiomyotomy with anterior Dor fundoplication and posterior partial fundoplication with posterior cruroraphy. Intraoperative complications (perforation of esophageal mucosa) occurred in 3 (42.9%) patients. Mean surgery time was 130±56 min, mean blood loss - 37 ml (35-205 ml), mean hospital-stay - 11.3±7.7 days. Postoperative complications Clavien-Dindo grade 3-4 were detected in 1 (14.3%) patient. One patient was diagnosed with bilateral pneumonia (SARS-Cov-2 infection) in 4 postoperative days. Median postoperative follow-up period was 22 months. Mean BMI in 6 months after surgery was 25.3±3.1 kg/m2, mean Eckardt score - 2.1±0.7 points, mean GERD-HRQL score - 3.3±0.9 points. CONCLUSION: Our data confirm the effectiveness and safety of the modified laparoscopic Heller procedure with Dor fundoplication as the main method for recurrent achalasia.

[Esophageal achalasia: possible pathogenic concepts from the perspective of modern notions]. / Akhalaziya kardii: vozmozhnye patogeneticheskie kontseptsii s pozitsii sovremennykh predstavlenii.

Esophageal achalasia is an esophageal motility disease characterized by impaired relaxation of lower esophageal sphincter (LES) and severe clinical symptoms. The main etiological factors and other essential aspects of pathogenesis and progression of this disorder are actively studied. To date, the question of significance of etiological factors is experimental and requires further study. In this review, the authors analyzed and summarized the modern data on etiology and pathogenesis of this disease considering the new researches devoted to this issue.
