Objective:To investigate the clinical efficacy of redo rectal resection and coloanal anastomosis.Methods:The retrospective and descriptive study was conducted. The clinicopatholo-gical data of 49 patients who underwent redo rectal resection and coloanal anastomosis for the treatment of local recurrence of tumors and failure of colorectal or coloanal anastomosis after rectal resection in the Sixth Affiliated Hospital of Sun Yat-sen University from November 2012 to December 2021 were collected. There were 32 males and 17 females, aged 57(range,31-87)years. Redo rectal resection and coloanal anastomosis was performed according to the patient′s situations. Observa-tion indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distri-bution were represented as M( Q1, Q3) or M(range). Count data were described as absolute numbers or percentages. Results:(1) Surgical situations. All 49 patients underwent redo rectal resection and coloanal anastomosis successfully, with the interval between the initial surgery and the reopera-tion as 14.2(7.1,24.3)months. The operation time and volume of intraoperative bold loss of 49 patients in the redo rectal resection and coloanal anastomosis was 313(251,398)minutes and 125(50,400)mL, respectively. Of the 49 patients, there were 38 cases receiving laparoscopic surgery including 12 cases with transanoscopic laparoscopic assisted surgery, 11 cases receiving open surgery including 2 cases as conversion to open surgery, there were 20 cases undergoing Bacon surgery, 14 cases undergoing Dixon surgery, 12 cases undergoing Parks surgery, 2 cases undergoing intersphincter resection and 1 case undergoing Kraske surgery, there were 20 cases undergoing rectum dragging out excision and secondary colonic anastomosis, 13 cases undergoing dragging out excision single anastomosis, 12 cases undergoing rectum dragging out excision double anastomosis, 4 cases undergoing first-stage manual anastomosis, there were 21 cases with enterostomy before surgery, 16 cases with prophylactic enterostomy after surgery, 12 cases without prophylactic enterostomy after surgery. The duration of postoperative hospital stay of 49 patients was (14±7)days. (2) Postoperative situations. Fifteen of 49 patients underwent postoperative complications, including 8 cases with grade Ⅱ Clevien-Dindo complications and 7 cases with ≥grade Ⅲ Clevien-Dindo complications. None of 49 patient underwent postoperative transferring to intensive care unit and no patient died during hospitalization. Results of postoperative histopathological examination in 23 patients with tumor local recurrence showed negative incision margin of the surgical specimen. (3) Follow-up. All 49 patients underwent post-operative follow-up of 90 days. There were 42 cases undergoing redo rectal resection and coloanal anastomosis successfully and 7 cases failed. Of the 37 patients with enterostomy, 20 cases failed in closing fistula, and 17 cases succeed. There were 46 patients receiving follow-up with the median time as 16.1(7.5,34.6)months. The questionnaire response rate for low anterior resection syndrome (LARS) score was 48.3%(14/29). Of the patients who underwent redo coloanal anastomosis and closure of stoma successfully, there were 9 cases with mild-to-moderate LARS.Conclusion:Redo rectal resection and coloanal anastomosis is safe and feasible for patients undergoing local recurr-ence of tumors and failure of colorectal or coloanal anastomosis after rectal resection, which can successfully restore intestinal continuity in patients and avoid permanent enterostomy.

Objective To evaluate the effect of sedation with regional anesthesia with dexmedeto-midine on postoperative cognitive function in elderly patients with diabetes mellitus. Methods A total of 180 elderly patients of either sex with diabetes foot, aged 65-80 yr, weighing 45-90 kg, of American So-ciety of Anesthesiologists physical status ⅡorⅢ, with preoperative Mini-Mental State Examination score>24, undergoing elective débridement, were divided into 2 groups(n=90 each)using a random number table: sedation with dexmedetomidine group(group D)and routine sedation control group(group C). Lumbar plexus block and sciatic nerve block were performed, after the reliable efficacy was achieved, dexmedetomidine was intravenously infused in a dose of 0.5 μg∕kg for 10 min followed by an infusion of 0.5 μg·kg-1·h-1until the end of surgery. Midazolam 0.02-0.04 mg∕kg was intravenously injected and mid-azolam 1 mg was injected intermittently during operation in group C. Ramsay sedation scores were main-tained between 2 and 4. At 30 min before surgery(T1), 1 h after the beginning of surgery(T2), at the end of surgery(T3), 6 h after the end of surgery(T4), and 24 h after the end of surgery(T5), venous blood samples were collected for determination of the level of blood glucose and plasma cortisol(Cor)con-centrations. Mini-Mental State Examination scores were assessed at 1 day before surgery and 1 and 3 days after surgery, and the occurrence of postoperative cognitive dysfunction was recorded in a short time period after operation. Results Compared with the baseline at T1, the level of blood glucose at T2-5and plasma Cor concentrations at T3,4were significantly increased in group C, and plasma Cor concentrations were sig-nificantly increased at T3,4(P<0.05), and no significant change was found in the level of blood glucose at T2-5in group D(P>0.05). Compared with group C, the level of blood glucose at T3-5and plasma Cor con-centrations at T3,4were significantly decreased, Mini-Mental State Examination scores were increased at 1 and 3 days after operation, and the incidence of postoperative cognitive dysfunction in a short time period after operation was decreased in group D(P<0.05). Conclusion Sedation with regional anesthesia with dexmedetomidine can improve postoperative cognitive function in elderly patients with diabetes mellitus.

Objective To investigate the effect of wire?reinforced epidural catheters on the success rate of epidural catheterization for labor analgesia. Methods A total of 200 nulliparous parturients who re?ceived labor analgesia voluntarily, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 20-45 yr, with body mass index<35 kg∕m2, were divided into 2 groups (n=100 each) using a random number table: common catheter group ( group Ⅰ) and reinforced catheter group ( group Ⅱ) . After suc?cessful epidural puncture, the corresponding catheter was inserted inⅠandⅡgroups. The development of difficult insertion, intravascular catheter insertion or paresthesia during insertion was defined as a failure of epidural catheterization. The occurrence of the failure of epidural catheterization was recorded. Results Compared with group Ⅰ, the failure rate of epidural catheterization was significantly decreased in groupⅡ( P<0.05) . Conclusion Wire?reinforced epidural catheters can raise the success rate of epidural catheter?ization for labor analgesia.

Objective To probe into the effect of early nursing intervention in promoting wake and complications of patients with severe traumatic brain injury. Methods 65 severe traumatic brain injury patients were divided into the control group (30 cases) and the intervention group (35 cases) randomly. The control group used conventional neurosurgical care, while in addition to conventional care, the inter-vention group also adopted early nursing intervention. The glasgow coma scale (GCS) score as well as gas-treintestinal bleeding, joint stiffness, central nervous fever and secondary infection went through comparative analysis in the two groups before and after treatment of patients using t test and χ2 test. Results Com-pared with the control group, the GCS score after treatment was higher, and the complications of gastroin-testinal bleeding, joint stiffness, central nervous fever and secondary infection were lower in the intervention group. Conclusions Early nursing intervention on patients with severe traumatic brain injury can accel-erate the awakening and reduce the occurrence of complications, it has practical significance to improve quality of life and reduce the financial burden of patients.
