Objective To summarize the research progress of transanal total mesorectal excision (TaTME) for rectal cancer. Methods The literatures about current status, limitations, and prospects of TaTME in China and abroad were collected to make an reviewe. Results TaTME is conformed to the principle of total mesorectal excision (TME), by using the ‘bottom-up’ approach and assisting in the laparoscopic technique platform, to ensure an adequate oncological distal margin, and it could improve the quality of the mesorectum specimens, reduce the circumferential margin involvement rate, afford more precise autonomic nerve preservation rate, and increase sphincter preservation rate. But it is also facing new complications, oncological and functional outcomes problems. Conclusions Although the experience with TaTME remains limited, the safety, feasibility, and short-term outcomes are acceptable. Nevertheless, there is a need for multicenter, large sample size, and long-term follow-up clinical studies focusing on the long-term outcomes to further improve the oncological safety of TaTME, before widespread application can be recommended.
ObjectiveTo evaluate the functional outcomes and quality of life in patients with surgery for slow transit constipation (STC).MethodsFrom March 2013 to July 2017, 29 patients undergoing total or subtotal colectomy for STC in our department were analyzed prospectively. Their preoperative and postoperative 1-year follow-up details were analyzed. Evacuation function of all patients was assessed by bowel movements, abdominal pain, bloating, straining, laxative, enema use and the Wexner constipation scales. Quality of life was evaluated by the Gastrointestinal Quality of Life Index (GIQLI) and the short-form (SF)-36 survey.ResultsA high number of patients (93.1%, 27/29) in STC stated that surgery received benefits to their health. Compared with that before operation, the number of bowel movements per week during a 1-year follow-up increased significantly (31.6±19.9 vs. 1.21±0.6, P<0.05). Significant trends toward improvement of bloating, straining, laxative and enema use were noted 1-year following surgery (P<0.05). The Wexner constipation scales scores during a 1-year follow-up decreased significantly (5.69±3.4 vs. 20.34±0.6, P<0.05). The GIQLI scores during a 1-year follow-up increased significantly (120.7±20.4 vs. 78.6±17.3, P<0.05). Moreover, results of SF-36 showed significant improvements in 7 spheres (role physical, role emotional, physical pain, vitality, mental health, social function and general health) during a 1-year follow-up compared with those before operation (P<0.05).ConclusionTotal or subtotal colectomy for STC did not only alleviate constipation symptoms dramatically, but also received significant improvements in the patients’ quality of life.
Objective To explore the impact of gender difference in 90-day outcomes after mechanical thrombectomy for acute cerebral infarction. Methods A prospective registration, observational, and retrospective analysis study was carried out. Patients with acute cerebral infarction who were admitted to the Department of Neurology of the First Affiliated Hospital of Chengdu Medical College and the Department of Neurology of Nanjing First Hospital between June 2015 and June 2019 were collected. Patients were divided into two groups based on gender. The detailed demographic, laboratory examination, imaging examination and clinical data were collected. Then, the data were analyzed using univariate and multivariate logistic regression analyses. Results A total of 298 patients were included. Among them, there were 185 males and 113 females. The differences in age, smoking, atrial fibrillation, using antiplatelet drugs before stroke, TOAST classification, and involved cerebrovascular sites between the two groups were statistically significant (P<0.05), and there was no statistically significant difference in other baseline data between the two groups (P>0.05). The results of univariate logistic regression analysis showed that the rate of 90-day favourable outcome of female patients was lower than that of male patients [odds ratio (OR)=0.462, 95% confidence interval (CI) (0.275, 0.775), P=0.030]. The results of multivariate logistic regression analysis showed that, after adjusting for confounding factors, there was no independent correlation between gender and the 90-day favourable outcome of patients with acute cerebral infarction who underwent mechanical thrombectomy [OR=1.511, 95% CI (0.745, 3.066), P=0.253]. Conclusion The gender has no significant effect on the 90-day favourable outcome of acute cerebral infarction patients treated with mechanical thrombectomy.
