ABSTRACT

Objective:To investigate the incidence and influencing factors of anastomotic leakage after laparoscopic anterior resection for rectal cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 804 patients with rectal cancer who were admitted to Peking Union Medical College Hospital of Chinese Academy of Medical Sciences from January 2017 to December 2019 were collected. There were 521 male and 283 female, aged 63(range, 27-94)years. All 804 patients underwent laparoscopic anterior resection for rectal cancer. Observation indicators: (1) surgical situations; (2) incidence of postoperative anastomotic leakage; (3) follow-up; (4) influencing factors of postoperative anastomotic leakage; (5) subgroup analysis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribu-tion were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Univariate analysis was conducted using the chi-square test or independent sample t test. Factors with P≤0.2 in univariate analysis were included in multivariate Logistic regression analysis. Results:(1) Surgical situations. All 804 patients underwent laparoscopic radical resection of upper and middle rectal cancer successfully, with the operation time and volume of intraoperative blood loss as 135(range, 118-256)minutes and 30(range, 5-350)mL. All 804 patients completed end-to-end colon rectal anastomosis, including 287 patients with reinforced sutures at the anastomotic site, and 517 patients with routine anastomosis. (2) Incidence of postoperative anastomotic leakage. Of the 804 patients, 40 patients had postoperative anastomotic leakage, with the incidence rate as 4.98%(40/804). (3) Follow-up. All 804 patients were followed up for 32(range, 6-49)months. None of patient died during the perioperative period. (4) Influencing factors of postoperative anastomotic leakage. Results of multivariate analysis showed that unreinforced suture at the anastomotic site was an independent risk factor for postoperative anastomotic leakage ( odds ratio=2.78, 95% confidence interval as 1.21-6.37, P<0.05). (5) Subgroup analysis. Of the 804 patients, 202 patients received neoadjuvant therapy and 602 patients did not receive neoadjuvant therapy. Of the 602 patients who did not receive neo-adjuvant therapy, cases with postoperative anastomotic leakage was 6 in the 253 patients with reinforced sutures, versus 21 in the 349 patients with routine sutures, showing a significant difference between them ( χ2=4.56, P<0.05). Conclusion:Unreinforced anastomosis at the anasto-motic site is an independent risk factor for anastomotic leakage after laparoscopic anterior rectal resection, especially for rectal cancer patients without neoadjuvant radiochemotherapy.

ABSTRACT

【Objective】 To investigate the perioperative rate of allogeneic red blood cell (RBC) transfusion in patients who underwent total knee arthroplasty (TKA) and its risk factors, and to identify its cross-match to transfusion ratio (C∶T ratio). 【Methods】 Anesthetic data of patients who underwent TKA from January 2014 to October 2019 in Peking Union Medical College Hospital were collected and analyzed retrospectively. Perioperative allogeneic RBC transfusion rate was calculated, and binary Logistic regression analysis was performed to identify its risk factors in these patients. The overall C∶T ratio was calculated and divided into subgroups based on surgery type and age group. 【Results】 The study enrolled 2 903 patients. The perioperative rate of allogeneic RBC transfusion in TKA patients was 10.9% (95% CI 9.8%~12.0%) and overall C∶T ratio was 5.6∶1. The independent risk factors leading to perioperative allogeneic RBC transfusion included advanced age(OR=1.025, 95% CI 1.009~1.042, P<0.01), preoperative hemoglobin level(OR=0.966, 95% CI 0.954~0.978, P<0.001), preoperative anemia(OR=3.543, 95% CI 2.052~6.119, P<0.001), hematological diseases(OR=6.462, 95% CI 2.479~16.841, P<0.001), bilateral surgery(OR=7.681, 95% CI 5.759~10.245, P<0.01) and revision surgery(OR=9.584, 95% CI 4.360~21.065, P<0.001). 【Conclusion】 The risk factors for perioperative allogeneic RBC transfusion in TKA patients included advanced age, preoperative low hemoglobin level, preoperative anemia, hematological diseases, bilateral surgery and revision surgery. Only type and screen tests are recommended if patients receiving unilateral primary TKA surgery are less than 75 years old without anemia and hematological diseases, while at least one to four units of blood should be cross-matched if patients are with preoperative anemia and hematological diseases or will receive bilateral and revision arthroplasty.

ABSTRACT

BACKGROUND@#Early fluid resuscitation is one of the fundamental treatments for acute pancreatitis (AP), but there is no consensus on the optimal fluid rate. This systematic review and meta-analysis aimed to compare the efficacy and safety of aggressive vs. controlled fluid resuscitation (CFR) in AP.@*METHODS@#The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and Web of Science databases were searched up to September 30, 2022, for randomized controlled trials (RCTs) comparing aggressive with controlled rates of early fluid resuscitation in AP patients without organ failure on admission. The following keywords were used in the search strategy: "pancreatitis," "fluid therapy,""fluid resuscitation,"and "randomized controlled trial." There was no language restriction. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to assess the certainty of evidence. Trial sequential analysis (TSA) was used to control the risk of random errors and assess the conclusions.@*RESULTS@#A total of five RCTs, involving 481 participants, were included in this study. For primary outcomes, there was no significant difference in the development of severe AP (relative risk [RR]: 1.87, 95% confidence interval [CI] 0.95-3.68; P = 0.07; n = 437; moderate quality of evidence) or hypovolemia (RR: 0.98, 95% CI: 0.32-2.97; P = 0.97; n = 437; moderate quality of evidence) between the aggressive and CFR groups. A significantly higher risk of fluid overload (RR: 3.25, 95% CI: 1.53-6.93; P <0.01; n = 249; low quality of evidence) was observed in the aggressive fluid resuscitation (AFR) group than the controlled group. Additionally, the risk of intensive care unit admission ( P = 0.02) and the length of hospital stay ( P <0.01) as partial secondary outcomes were higher in the AFR group. TSA suggested that more studies were required to draw precise conclusions.@*CONCLUSION@#For AP patients without organ failure on admission, CFR may be superior to AFR with respect to both efficacy and safety outcomes.@*REGISTRATION@#PROSPERO; https://www.crd.york.ac.uk/PROSPERO/ ; CRD 42022363945.

ABSTRACT

BACKGROUND@#Many nutritional supplements and pharmacological agents have been reported to show preventive effects on colorectal adenoma and colorectal cancer (CRC). We performed a network meta-analysis to summarize such evidence and assess the efficacy and safety of these agents.@*METHODS@#We searched PubMed, Embase, and the Cochrane Library for studies published in English until October 31, 2021 that fit our inclusion criteria. We performed a systematic review and network meta-analysis to assess the comparative efficacy and safety of candidate agents (low-dose aspirin [Asp], high-dose Asp, cyclooxygenase-2 inhibitors [coxibs], calcium, vitamin D, folic acid, ursodeoxycholic acid [UDCA], estrogen, and progesterone, alone or in combination) for preventing colorectal adenoma and CRC. Cochrane risk-of-bias assessment tool was employed to evaluate the quality of each included study.@*RESULTS@#Thirty-two randomized controlled trials (278,694 participants) comparing 13 different interventions were included. Coxibs significantly reduced the risk of colorectal adenoma (risk ratio [RR]: 0.59, 95% confidence interval [CI]: 0.44-0.79, six trials involving 5486 participants), advanced adenoma (RR: 0.63, 95% CI: 0.43-0.92, four trials involving 4723 participants), and metachronous adenoma (RR: 0.58, 95% CI: 0.43-0.79, five trials involving 5258 participants) compared with placebo. Coxibs also significantly increased the risk of severe adverse events (RR: 1.29, 95% CI: 1.13-1.47, six trials involving 7109 participants). Other interventions, including Asp, folic acid, UDCA, vitamin D, and calcium, did not reduce the risk of colorectal adenoma in the general and high-risk populations compared with placebo.@*CONCLUSIONS@#Considering the balance between benefits and harms, regular use of coxibs for prevention of colorectal adenoma was not supported by the current evidence. Benefit of low-dose Asp for chemoprevention of colorectal adenoma still requires further evidence.@*REGISTRATION@#PROSPERO, No. CRD42022296376.

ABSTRACT

Objective:To evaluate the effect of teacher-assisted jaw thrust maneuver on the learning effectiveness of Bonfils fiberscope-guided tracheal intubation for the beginners.Methods:Forty-eight accompanying physicians who were receiving residents standardized training in the Department of Anesthesiology, Peking Union Medical College from April, 2020 to March 2021 and served as trainees were enrolled in this study.The trainees received Bonfils fiberscope training and were randomly divided into independent group ( n=24) and assisted group ( n=24). After induction of general anesthesia, the trainees independently performed the Bonfils fiberscope-guided endotracheal intubation operation in independent group, and trainees performed the operation with the assistance of the teacher′s jaw thrust maneuver in assisted group.The success of intubation at first attempt, duration of intubation, times of teachers′ guidance and scores for trainees′ learning confidence were recorded. Results:Compared with independent group, the success rate of intubation at first attempt was significantly increased, the duration of intubation was shortened, scores for trainees′ learning confidence was increased ( P<0.05), and no significant change was found in the times of teachers′ guidance in assisted group ( P>0.05). Conclusion:For the beginners learning Bonfils fiberscope-guided tracheal intubation, teacher-assisted jaw thrust maneuver is helpful in raising the learning effectiveness and increasing the beginners′ learning confidence.

ABSTRACT

Objective:To compare the effects of different anesthetic methods on the prognosis in the patients with stage Ⅲ breast cancer.Methods:Based on a multicenter randomized controlled trial (NCT00418457), 274 patients with untreated stage Ⅲ breast cancer, aged 18-85 yr, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, were enrolled in the study and assigned to thoracic paravertebral block (TPVB) combined with total intravenous anesthesia group (TPVB+ TIVA group, n=141) and general anesthesia group (GA group, n=133) by computer-generated randomization stratified by study site.The primary outcome parameter of this study was postoperative recurrence rate.The secondary outcome parameters were the degree of postoperative acute pain (assessed using visual analogue scale score), the incidence of postoperative nausea and vomiting (PONV), postoperative hospital stay time, and the incidence of persistent pain after breast cancer surgery (PPBCS) at 6 and 12 months after surgery (assessed using the modified Brief Pain Inventory). Results:Compared with group GA, no significant change was found in the postoperative recurrence rate ( HR=0.711, 95% confidence interval (CI) 0.418-1.210, P=0.209), the degree of postoperative acute pain and the incidence of PONV were decreased (mean difference ( MD) of visual analogue scale score -0.890, 95% CI -1.344--0.436, P<0.001; OR=0.236, 95% CI 0.083-0.674, P=0.007), and no significant change was found in postoperative hospital stay time and the incidence of PPBCS ( HR=1.000, 95% CI 0.778-1.286, P=1.000; OR=2.100, 95% CI 0.599-7.362, P=0.246) in group TPVB+ TIVA. Conclusion:Compared with general anesthesia alone, TPVB combined with total intravenous anesthesia can provide lower degree of postoperative acute pain and lower incidence of PONV, and exert no effects on postoperative recurrence, postoperative hospital stay time and PPBCS in patients with stage Ⅲ breast cancer.
