Perioperative management of patients in both groups will be carried out in accordance with the guidelines for accelerated recovery after surgery (ERAS). The primary endpoint of the study will be the six-minute walk test (6MWT). Secondary endpoints will be: number of postoperative complications (by Clavien-Dindo), duration of the postoperative period, postoperative mortality, quality of life of patients and adherence of patients to the passage of the prehabilitation program.DISCUSSION AND CONCLUSION: it is expected that short-term unimodal prehabilitation will improve the functional reserves of patients, reduce the duration of inpatient treatment and reduce the number and severity of postoperative complications, which can lead to a decrease in postoperative mortality and an improvement in the quality of life of patients.

Odds ratio (OR) and 95% confidence interval (95% CI) were used as the treatment effect measure for comparing results. Combined overall effect measures were calculated for a random effect model. All analyses were performed using the Review Manager 5.3 software.RESULTS: eighteen non-randomized studies, including a total of 2,999 patients (1,737 PTR and 1,262 chemo/RT) were identified. Gender, age, site of primary tumor and distant metastasis of patients were comparable between groups in all analyzed studies. Two-year (38.2% vs. 21.1%; OR 0.42; 95% CI 0.28–0.64; p < 0.0001) and 5-year (12.7% vs. 5.3%; OR 0.45; 95% CI 0.21–0.97; p = 0.04) overall survival rates were significantly higher in the PTR group than in the chemo/RT group. No significant differences in 30-day mortality rate between the two groups (1.7% vs. 1%; OR 1.92; 95% CI 0.79–4.68; p = 0.15). However, the rate of surgical intervention due to complications of first treatment was significantly lower in the PTR group comparing to the chemo/RT group (2.3% vs. 14.53%; OR 0.18; 95% CI 0.08–0.40; p < 0.0001). At the same time, one hundred and fourteen patients (13.8%; OR 0.19; 95% CI 0.09–0.40; p < 0.0001) in the chemo/RT group required surgery for symptoms associated with a primary tumor.CONCLUSIONS: PTR in patients with asymptomatic or minimally symptomatic CRC and synchronous unresectable metastases significantly improves overall survival, allows to prevent surgical intervention due to complications related to primary tumor and is not associated with increased postoperative mortality rate comparing to systemic chemotherapy/radiotherapy as a treatment of first line. The current data are based on non-randomized comparative studies and data from early terminated randomized controlled trials (RCTs) and further well-designed RCTs are required.","PeriodicalId":17840,"journal":{"name":"Koloproktologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73279664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 20 (19.4%) of 103 patients, the course of the immediate postoperative period was complicated by the development of neurogenic bladder dysfunction. In order to study the frequency of neurogenic bladder dysfunction depending on the technique of mesorectumectomy, the patients were divided into 2 groups. Group 1 included 9 patients who underwent laparoscopic total mesorectumectomy. Group 2 included 11patients who underwent traditional (open) mesorectumectomy.RESULTS: the study of the functional state of the bladder according to the flowmetric indicators revealed that the frequency of development of postoperative bladder dysfunction has a gender dependence. The frequency of neurogenic bladder dysfunction was 25% in men and 10,7% in women. It is shown that during 1 week and 6 months after surgery, the average urination rate tends to increase in women and decrease in men, regardless of the technique of total mesorectumectomy. In both groups, there was not a statistically significant decrease in the maximum volumetric velocity in both men and women within 6 months after surgery. At the same time, during this period, there was a decrease in the average rate of urination only in men, regardless of the technique of total mesorectumectomy. And in women, this indicator remained unchanged or slightly increased.CONCLUSION: it is shown that a complex system of therapeutic measures, including drug stimulation of the detrusor and urethral sphincter, repeated catheterization of the bladder, as well as epicystostomy performed according to indications, allows adequate correction of bladder dysfunction after total mesorectumectomy in patients with rectal cancer.","PeriodicalId":17840,"journal":{"name":"Koloproktologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89953254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
