ObjectiveTo analyze the current version of the West China Database from Colorectal Cancer (DACCA) and explore how the occupational background of colorectal cancer patients affects the complexity of surgical difficulty and postoperative complications. MethodsWhen using the updated version of DACCA data on May 28, 2023 for analysis, the data items concerned covered occupation, operative duration, anatomical difficulty, pelvic stenosis, abdominal obesity, adhesion in surgical area, abnormal mesenteric status, tissue or organ hypertrophy, intestinal quality in surgical area, postoperative complications in hospital, short-term postoperative complications and long-term postoperative complications. According to the “Occupational Classification Code of the People’s Republic of China”, the occupations of patients were divided into professional and technical personnel, staff, service personal, production personnel, manufacturing personnel and retirees according to different occupations. The operative difficulty and postoperative complications of 6 groups were analyzed. ResultsAccording to the screening conditions, 5 734 valid data rows were obtained from DACCA. The results of occupation analysis showed that there were significant difference in operative duration (H=11.609, P=0.041), anatomical difficulty (H=29.166, P<0.001), pelvic stenosis (H=16.412, P=0.006), abdominal obesity (H=44.622, P<0.001), adhesion in surgical area (H=23.695, P<0.001), abnormal mesenteric status (χ2=39.252, P=0.035), tissue or organ hypertrophy (χ2=58.284, P<0.001) and intestinal quality in surgical area (H=21.041, P=0.001) between different groups. There were no significant differences in the occurrence of complications in hospital, near and short-term and long-term after operation among different occupations (P>0.05). Further subgroup analysis showed that only the difference of fever (χ2=10.969, P=0.041) and intestinal obstruction (χ2=12.025, P=0.021) were statistically significant among different occupations. ConclusionThe occupation of patients may affect the difficulty of colon cancer surgery, and the occurrence of postoperative complications is nothing to do with the occupation of patients, but the occurrence of postoperative fever and postoperative intestinal obstruction is related to occupations, and the possible causes need to be further explored.
ObjectiveTo compare the effects of transthoracic device closure and traditional surgical repair on atrial septal defect systemically.MethodsA systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Wanfang Database up to July 31, 2018 to identify trials according to the inclusion and exclusion criteria. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted by RevMan 5.3 and Stata 12.0 software.ResultsThirty studies were identified, including 3 randomized controlled trials (RCTs) and 27 cohort studies involving 3 321 patients. For success rate, the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.34, 95%CI 0.16 to 0.69, P=0.003). There was no statistical difference in mortality between the two groups (CCT, OR=0.43, 95%CI 0.12 to 1.52, P=0.19). Postoperative complication occurred less frequently in the transthoracic closure group than that in the surgical repair group (RCT, OR=0.30, 95%CI 0.12 to 0.77, P=0.01; CCT, OR=0.27, 95%CI 0.17 to 0.42, P<0.000 01). The risk of postoperative arrhythmia in the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.56, 95%CI 0.34 to 0.90, P=0.02). There was no statistical difference in the incidence of postoperative residual shunt in postoperative one month (CCT, OR=4.52, 95%CI 0.45 to 45.82, P=0.20) and in postoperative one year (CCT, OR=1.03, 95%CI 0.29 to 3.68, P=0.97) between the two groups. Although the duration of operation (RCT MD=–55.90, 95%CI –58.69 to –53.11, P<0.000 01; CCT MD=–71.68, 95%CI –79.70 to –63.66, P<0.000 01), hospital stay (CCT, MD=–3.31, 95%CI –4.16, –2.46, P<0.000 01) and ICU stay(CCT, MD=–10.15, 95%CI –14.38 to –5.91, P<0.000 01), mechanical ventilation (CCT, MD=–228.68, 95%CI –247.60 to –209.77, P<0.000 01) in the transthoracic closure group were lower than those in the traditional surgical repair group, the transthoracic closure costed more than traditional surgical repair during being in the hospital (CCT, MD=1 221.42, 95%CI 1 124.70 to 1 318.14, P<0.000 01).ConclusionCompared with traditional surgical repair, the transthoracic closure reduces the hospital stay, shortens the length of ICU stay and the duration of ventilator assisted ventilation, while has less postoperative complications. It is safe and reliable for patients with ASD within the scope of indication.
ObjectiveTo investigate the predictive value of prognostic nutritional index (PNI) in complications after thoracoscopy-assisted radical resection of esophageal cancer.MethodsWe collected the clinical data of patients who underwent thoracoscopy-assisted esophagectomy in the First Affiliated Hospital of Xinjiang Medical University from January 2015 to June 2020. The predictive value of PNI for postoperative complications was evaluated by establishing receiver operating characteristic (ROC) curve and the optimal cut-off point was determined. The patients were divided into a high PNI group and a low PNI group according to the cut-off point. The differences of baseline data and perioperative complications-related indicators between the two groups were compared and analyzed. Univariate and multivariate analyses were used to investigate the influence of PNI and other related indexes on postoperative complications.ResultsA total of 116 patients were enrolled in this study, including 75 males and 41 females, aged 65 (58-69) years. The area under ROC curve was 0.647, and the optimal cut-off point was 51.9. According to the cut-off point, there were 45 patients in the high PNI group and 71 patients in the low PNI group. The overall complication rate (χ2=10.437, P=0.001) and the incidence of postoperative pulmonary infection (χ2=10.811, P=0.001) were statistically different between the two groups. The results of univariate analysis showed that the duration of ventilator use (Z=–3.136, P=0.002), serum albumin value (t=2.961, P=0.004), and PNI value (χ2=10.437, P=0.001) were the possible risk factors for postoperative complications after thoracoscopy-assisted esophagectomy. The results of multivariate analysis suggested that the duration of ventilator use (OR=1.015, P=0.002) and the history of drinking (OR=5.231, P=0.013) were independent risk factors for postoperative complications, and high PNI was the protective factor for postoperative complications (OR=0.243, P=0.047).ConclusionPNI index has a certain value in predicting postoperative complications, which can quantify the preoperative nutritional and immune status of patients. Drinking history and duration of ventilator use are independent risk factors for postoperative complications of thoracoscopy-assisted esophagectomy, and high PNI is a protective factor for postoperative complications.
ObjectiveTo investigate the clinical effect and the incidence of postoperative complications of Milligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids.MethodsProspectively collected 120 patients with annular mixed hemorrhoids who received treatment from the Department of Colorectal Surgery of Bazhong Hospital of Traditional Chinese Medicinel during the April, 2016 to October, 2018. All of the 120 patients with annular mixed hemorrhoids were randomly divided into the experimental group and the control group, with 60 patients in each one group. Patients in the experimental group was treated with Milligan-Morgan hemorrhoids combined with reducing tension of alary incision, while patients in the control group with conventional Milligan-Morgan hemorrhoid.ResultsIn the experimental group, 49 cases were cured, 11 cases showed obvious effect; in the control group, 39 cases were cured, 20 cases showed obvious effect, and 1 case was effective. The curative effect in experimental groups was better than that of the control group (Z=–2.090, P=0.037), and the effective rates of these two group were both 100% in total. The mean healing time was (19±3) d (14–21 d) in the experimental group and (21±3) d (14–24 d) in the control group, respectively, which was better in the experimental group (Z=–13.636, P<0.001). Experimental group with lower score of wound pain, hemafecia, and anal margin edema, which were much better than control group on 1 d and 3 d after operation (P<0.05). There was no statistically significant differences on incidence of uroschesis and recurrence rate between the two groups (P>0.05).ConclusionsMilligan-Morgan hemorrhoids combined with reducing tension of alary incision in the treatment of annular mixed hemorrhoids has good clinical effect and deserves clinical application.
ObjectiveTo explore the treatment strategies for patients with fever and pulmonary complications after thoracic surgery during COVID-19 epidemic.MethodsThe clinical data of 537 patients who ungerwent selective surgery at the Department of Thoracic Surgery, Shangjin Branch of West China Hospital between February and December 2020 were retrospectively analyzed, including 242 (45.1%) males and 295 (54.9%) females aged 53.3±13.4 years. We have established a procedure for the patients with fever and pulmonary complications after thoracic surgery to investigate the cause of the disease and track risk factors.ResultsThe overall postoperative complication rate was 16.4% (88/537), and 1 (0.2%) patient died. Of 537 patients, 179 (33.3%) patients were enrolled in our model according to the inclusion criteria: ratio of males [112 (62.6%) vs. 130 (36.3%), P<0.010], patients with a history of smoking [74 (41.3%) vs. 87 (24.3%), P<0.010], or with esophageal cancer surgery [36 (20.1%) vs. 15 (4.2%)], or with traditional thoracotomy [14 (7.8%) vs. 4 (1.1%)] was higher than that of the other patients. Patients in our process due to fever or pulmonary complications had longer ICU stay and postoperative hospital stay (P=0.010). Logistic regression multivariate analysis showed that gender was an independent risk factor for postoperative fever or pulmonary complications.ConclusionIn low-risk areas of the epidemic, the treatment process is simple and feasible, and the cause traceability and corresponding treatment can basically be completed within 24 hours. At the same time, the treatment process has been running stably for a long time.
ObjectiveTo evaluate the safety and feasibility of non-nasogastric tube throughout the perioperative period of classical Whipple pancreaticoduodenectomy. MethodsA retrospective analysis was conducted on the clinical data of 63 patients who underwent Whipple pancreaticoduodenectomy at West China Hospital of Sichuan University from June 2020 to August 2023. According to whether nasogastric tube was placed throughout the perioperative period, the patients were divided into nasogastric tube group (NGT group, n=32) and no nasogastric tube group (no NGT group, n=31). The intraoperative indicators such as gastrointestinal anastomosis mode and outcome measures such as postoperative hospital stay were compared between the two groups. Results① Preoperative baseline data: the proportion of benign diseases (P=0.005) and preoperative pancreatitis (P=0.003) of the no NGT group were higher than those of the NGT group, and other preoperative baseline data, such as age and sex, were not statistically significant (P>0.05). ② Intraoperative index: the proportion of circular stapler (P=0.009) was smaller and the operation time was shorter (P<0.001), but there was no significant difference in the anastomosis, intraoperative blood transfusion and intraoperative bleeding (P>0.05). ③ Postoperative outcome measures: the postoperative length of hospital stay (P<0.001) and the incidence of delayed gastric emptying (P<0.001) of the no NGT group were lower than those in the NGT group, but the postoperative time of food intake, incidence of pancreatic fistula, incidence of postoperative bleeding, and Clavien-Dindo grade of complications were not significant (P>0.05), and on one died within 30 d after operation. ConclusionsThe results of this study preliminarily show that, it is safe and feasible not to place nasogastric tubes throughout the perioperativeperiod in patients undergoing classical Whipple pancreaticoduodenectomy. Compared with placing nasogastric tube, it can shorten the postoperative hospital stay, reduce the incidence of postoperative delayed gastric emptying.
ObjectiveTo investigate factors associated with postoperative complications after laparoscopic radical surgery in rectal cancer.MethodsThe clinical data of patients with rectal cancer performed by the laparoscopic radical resection from February 2013 to December 2016 were analyzed retrospectively. All the data were analyzed by the t test, chi-square test or logistic regression analysis.ResultsThere were 343 patients with rectal cancer performed by the laparoscopic radical resection. The postoperative complications occurred in the 97 (28.3%) patients. The result of univariate analysis showed that the postoperative complications rate was associated with the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location and diameter of tumor, operative time, and surgeon experience (all P<0.050). The results of logistic regression analysis revealed that the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience were the independent risk factors for the postoperative complications (all P<0.050).ConclusionGender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience are independent risk factors for postoperative complications in laparoscopic radical rectal surgery for rectal cancer.
Objective To evaluate the clinical effectiveness and safety of different mesh fixation techniques in laparoscopic trans-abdominal preperitoneal hernia repair (TAPP) by using network meta-analysis. Methods CNKI, WanFang Data, VIP, CBM, the Cochrane Library, PubMed, Embase, and Web of Science databases were retrieved to collect randomized controlled trials (RCTs) studies comparing different fixation methods of patches in laparoscopic TAPP. The retrieval time limit was from the establishment of the database to March 1, 2022. After two researchers independently screened the literatures, extracted the data, and evaluated the bias risk, Bayesian network meta-analysis was conducted by using R4.1.2 software. Results Twenty-nine RCTs were included, including 4 095 patients. The results of network meta-analysis showed that the risk of chronic postoperative inguinal pain was higher in staples fixation than that of no fixation [OR=0.06, 95%CI (0.01, 0.26), P＜0.001], glue fixation [OR=0.21, 95%CI (0.04, 0.53), P=0.001] and self-gripping mesh [OR=0.09, 95%CI (0.01, 0.52), P=0.009], the incidence of chronic postoperative inguinal pain with suture fixation was higher than that with no fixation [OR=0.10, 95%CI (0.01, 0.70), P= 0.020]. Postoperative visual analogue scale of staples fixation was higher than those of no fixation [MD=–0.90, 95%CI (–1.49, –0.33), P=0.002] and glue fixation [MD=–0.92, 95%CI (–1.35, –0.49), P＜0.001], the postoperative visual analogue scale with suture fixation was higher than those of no fixation [MD=–0.83, 95%CI (–1.61, –0.08), P=0.030] and glue fixation [MD=–0.85, 95%CI (–1.56, –0.13), P=0.020]. There was no significant difference in the incidence of seroma and hematoma, hospital stay and hernia recurrence among different fixation methods. Conclusions The network meta-analysis shows that medical glue and self-gripping mesh have certain advantages in reducing chronic pain after surgery, which may be the better patch fixation method in TAPP. The non fixation mesh will not increase the risk of postoperative recurrence, and can be used in clinical practice. This conclusion needs to be further verified by large sample, long-term follow-up and high-quality RCTs.
Objective To analyze the influence of the ABO blood types of colorectal cancer patients served by West China Hospital as a regional center on surgical characteristics and postoperative complications in the current version of Database from Colorectal Cancer (DACCA). Methods The DACCA version was updated on January 5, 2022. The data items included ABO blood type, sex, type of operation, nature of operation and postoperative complications. The operative characteristics and complications at different stages after operation (in hospital, short-term and long-term after operation) of colorectal cancer patients with different blood types (A, B, AB, O) were analyzed. Results According to the DACCA database, we obtained 5 010 analysable data rows, covering 2005–2022. The results of blood types analysis showed that there was no significant difference among different blood types in the overall postoperative complications and the occurrence of complications in hospital, short-term and long-term after operation (P>0.05). Further subgroup analysis showed that only the difference of anastomotic leakage among different blood types was statistically significant (χ2=9.588, P=0.022). There was no significant difference among different blood types in whether the primary focus of colon cancer surgery was removed or not, the degree of radical resection of the primary focus, and whether the anus was preserved or not in rectal cancer surgery (P>0.05), and there was significant difference among different blood types with different degrees of radical resection of primary rectal cancer (χ2=15.773, P=0.001). Conclusions The ABO blood types of patients with colorectal cancer has nothing to do with the occurrence of overall complications in the short and long term after operation, and has no impact on the implementation of different surgical methods. However, the occurrence of a single postoperative anastomotic leakage is related to blood type, and its possible causes need to be further explored.
Objective To investigate the risk factors of hypoproteinemia after laparoscopic assisted radical gastrectomy for gastric cancer and its influence on recent clinical outcome. Methods Retrospective case-control study was carried out. Clinical data of 135 patients underwent laparoscopic assisted radical gastrectomy for gastric cancer admitted to the Department of General Surgery in the First Affiliated Hospital of Xi’an Jiaotong University Medical College from June 2016 to June 2021 were collected. Postoperative hypoproteinemia was defined as serum albumin <30 g/Lon postoperative day 1. Observation indications: ① the incidence of hypoproteinemia after laparoscopic assisted radical gastrectomy for gastric cancer; ② analysis of risk factors for postoperative hypoproteinemia; ③ influence of postoperative hypoproteinemia on recent clinical outcome. Results ① Among 135 patients, 56 patients developed hypoproteinemia after operation (hypoproteinemia group) with an incidence of 41.5%, 79 patients without hypoproteinemia (non- hypoproteinemia group). ② Univariate analysis of risk factors for postoperative hypoproteinemia showed that age, preoperative albumin level, preoperative plasma volume, preoperative leukocyte, preoperative hemoglobin level, maximum tumor diameter, net intake on operative day and operative time were related to the occurrence of postoperative hypoproteinemia (P<0.05). The results of multivariate analysis showed that: age ≥65 years [OR=6.320, 95%CI (2.340, 17.068), P＜0.001], preoperative albumin level <35 g/L [OR=5.951, 95%CI (1.815, 19.507), P=0.003], operative time ≥5 h [OR=3.171, 95%CI (1.164, 8.640), P=0.024], and net intake on operative day ≥3 000 mL [OR=5.153, 95%CI (1.616, 16.432), P=0.006] were risk factors for postoperative hypoproteinemia. ③ Within 30 days after operation, the incidence of non surgery related complications in the hypoproteinemia group and the non-hypoproteinemia group were 30.4% (17/56) and 13.9% (11/79), respectively, and the incidence of surgery related complications were 10.7% (6/56) and 1.3% (1/79), respectively, with statistically significant differences (P<0.05). Conclusions Age ≥65 years, preoperative albumin level <35 g/L, operative time ≥5 h and net intake on operative day ≥3 000 mL are risk factors for hypoproteinemia after laparoscopic assisted radical gastrectomy. For patients suffered from hypoproteinemia (albumin <30 g/L) after surgery, the incidences of both surgery-related complications and non-surgery-related complications increase.
