Objective To explore the therapeutic effect of mild hypothermia on the inflammatory response, organ function and outcome in perioperative patients with acute Stanford type A aortic dissection (AAAD). Methods From February 2017 to February 2018, 56 patients with AAAD admitted in our department were enrolled and randomly allocated into two groups including a control group and an experimental group. After deep hypothermia circulatory arrest during operation, in the control group (n=28), the patients were rewarmed to normal body temperatures (36 to 37 centigrade degree), and which would be maintained for 24 hours after operation. While in the experimental group (n=28), the patients were rewarmed to mild hypothermia (34 to 35 centigrade degree), and the rest steps were the same to the control group. The thoracic drainage volume and the incidence of shivering at the first 24 hours after operation, inflammatory indicators and organ function during perioperation, and outcomes were compared between the two groups. There were 20 males and 8 females at age of 51.5±8.7 years in the control group, 24 males and 4 females at age of 53.3±11.2 years in the experimental group.Results There was no obvious difference in the basic information and operation information in patients between the two groups. Compared to the control group, at the 24th hour after operation, the level of peripheral blood matrix metalloproteinases (MMPs) was lower than that in the experimental group (P=0.008). In the experimental group, after operation, the awakening time was much shorter (P=0.008), the incidence of bloodstream infection was much lower (P=0.019). While the incidence of delirium, acute kidney injury (AKI), hepatic insufficiency, mechanical ventilation duration, intensive care unit (ICU) stays, or hospital mortality rate showed no statistical difference. And at the first 24 hours after operation, there was no difference in the thoracic drainage volume between the two groups, and no patient suffered from shivering. Conclusion The mild hypothermia therapy is able to shorten the awakening time and reduce the incidence of bloodstream infection after operation in the patients with AAAD, and does not cause the increase of thoracic drainage volume or shivering.
ObjectiveTo summarize the functional outcomes of transanal total mesorectal excision (TaTME).MethodThe literatures about functional outcomes and existing problems secondary to TaTME in China and abroad were collected to make a review.ResultsNeither the TaTME or the laparoscopic TME (LTME) had few serious impact on the quality of life of patients. At present, only a few studies were involved in the postoperative sexual function, and no definite conclusion could be drawn. From the current data only, the TaTME had few serious impact on the sexual function and it didn’t show some advantages as compared with the LTME. The urinary and defecation functions showed no obvious differences between the TaTME and the LTME, which of the patients after the TaTME might be impaired to some extent. The defecation disorders mainly occurred in 1—6 months after the TaTME, but it would recover to a certain extent as time went on.ConclusionsAlthough TaTME has more advantages in protecting pelvic autonomic nerves, there is no obvious difference in postoperative organ function as compared with LTME surgery at present. Multi-center, large sample size, and long-term follow-up studies are still needed to validate long-term results.
