BACKGROUND/AIMS: Resection of the diseased segment and suture of the victim segment is recommended for enteroenteric fistula in Crohn's disease (CD). The main difficulty in this procedure remains reliable diagnosis of the victim segment, especially for fistulas found intraoperatively and inaccessible on endoscopic examination. We aimed to explore whether intraoperative inspection alone is reliable. METHODS: Patients undergoing conservative surgery between 2011 and 2016 for enteroenteric fistulas complicating CD were identified from a prospectively maintained database. Patients were divided according to whether the victim segment was evaluated by preoperative endoscopy + intraoperative inspection (PI group) or by intraoperative inspection alone (I group). Outcomes were compared. RESULTS: Of 65 patients eligible for the study, 37 were in in the PI group and 28 were in the I group. The baseline characteristics were similar between the groups, except for the rate of emergency surgery (0/37 in PI group vs. 5/28 in I group, P=0.012). Fistulas involved more small intestines (4/37 in PI group vs. 15/28 in I group, P < 0.001) and fewer sigmoid colons (17/37 in PI group vs. 4/28 in I group, P=0.008) in I group due to accessibility with endoscopy. No difference was found in postoperative complications, stoma rates, postoperative recurrence, or disease at the repair site between the 2 groups (P>0.05). CONCLUSIONS: For fistulas found intraoperatively and inaccessible on endoscopic examination, intraoperative inspection was a reliable guide when choosing between en bloc resection and a conservative procedure.

Objective:To compare the application value of different polypropylene mesh in inguinal hernia repair of adults.Methods:The prospective cohort study was conducted. The clinical data of 120 adult patients with inguinal hernia who were admitted to two medical centers (60 in Huadong Hospital affiliated to Fudan University and 60 in Shanghai Ninth People′s Hospital affiliated to Shanghai Jiaotong University from March 2012 to Match 2014 were collected. Patients were randomly divided into study group and control group using the random number table. Patients in the study group underwent repair of inguinal hernia using the SMP95958X mesh, and patients in the control group underwent repair of inguinal hernia using the modified Kugel mesh. All patients underwent preperitoneal repair by senior hernia surgery specialists. Observation indicators: (1) postoperative pain; (2) complications and follow-up. Patients were followed up at postoperative 3 months and 6 months using outpatient examination to detect the short-term complications by physical or color doppler ultrasonography examination, and at postoperative 5 years using telephone interview or outpatient examination to detect long-term complications including infection, foreign body sensation and recurrence of hernia. The follow-up was up to March 2019. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range), comparison between groups was analyzed using the nonparametric rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square, continuous correction chi-square test or Fisher exact probability. Comparison of ranked data were analyzed using the nonparametric rank sum test. Results:A total of 118 patients with inguinal hernia were selected for eligibility, including 116 males and 2 females, aged (64±12)years, with a range from 29 to 84 years. Of the 118 patients, 59 were in the study group and 59 were in the control group, respectively. (1) Postoperative pain: of the 59 patients in the control group, 34 took painkiller and 1 case lost the data of taking painkiller at postoperative 2 days. Of the 59 patients in the study group, 29 cases took painkiller. There was no significant difference in taking painkiller between the two groups ( χ2=1.055, P>0.05). The pain score at postoperative 2 days and 3 months were 3.26(range, 0.70-6.90) and 0.87(range, 0.00-4.10) of the control group, respectively, and 3.03(range, 0.00-8.80) and 0.83(range, 0.00-3.10) of the study group, respectively, showing no significant difference between the two groups ( Z=0.782, 0.729, P>0.05). (2) Complications and follow-up: the incidence of postoperative complications at perioperative period (within postoperative 2 days) was 1.7%(1/59) and 1.7%(1/59) in the control group and study group, respectively, showing no significant difference between the two groups ( P>0.05). Both of 59 patients in the control group and study group were followed up for 6 months after operation, respectively. The incidence of postoperative complications at 3 months and 6 months after operation was 1.7%(1/59) and 1.7%(1/59) in the control group, respectively, and 5.1%(3/59) and 5.1%(3/59) in the study group, showing no significant difference between the two groups ( P>0.05). Fifty-five patients of the control group and 52 patients of the study group were followed up for 5 years after operation, respectively. There was 1 case of infection in the control group, with the incidence of postoperative long-term ( within 5 years after operation) complication of 1.8%(1/55), and there were 2 cases of infection and 1 case of foreign body sensation in the study group with the incidence of postoperative long-term (within 5 years after operation) complication of 5.8%(3/52), showing no significant difference between the two group ( P>0.05). There was no recurrence of hernia in either group. Conclusion:Both of the SMP95958X mesh and the modified Kugel mesh can be used in preperitoneal repair of inguinal hernia, showing no significant difference in the efficacy between them.

Objective:To investigate the impact of initial recurrence site on the prognosis of patients with pancreatic cancer after radical operation.Methods:Clinical data of 172 patients who underwent radical resection of pancreatic cancer and were pathologically confirmed as pancreatic ductal adenocarcinoma in Ningbo University Affiliated Lihuili Hospital from January 2015 to June 2021 were analyzed retrospectively. According to the classification of the initial recurrence or metastasis after operation: no recurrence, local recurrence (residual pancreas, mesenteric vein, pancreaticoenterostomy surrounding tissue), liver metastasis, abdominal or retroperitoneum metastasis, multiple site recurrence and other pattern recurrence. The effect on prognosis was analyzed by COX risk ratio model, the overall survival and recurrence-free survival were calculated by Kaplan-Meier, and the survival curve was drawn. Log-rank test was used to compare the survival rate of different recurrence sites and different treatments after recurrence.Results:12 patients had local recurrence, 69 had liver metastasis, 25 had abdominal or retroperitoneal metastasis, 17 had multiple site recurrence, and 5 had other site recurrence and 44 had no recurrence. The median follow-up time was 15.5 months (3-69 months). The median overall survival was 19 months (95% CI 16.273-21.727). The 1- , 3- and 5-year postoperative cumulative survival rate was 71.0%, 27.8% and 20.2%, respectively. Univariate analysis showed that CA125, tumor size, lymph node metastasis, microvascular invasion, tumor differentiation degree, adjuvant chemotherapy, initial recurrence site were significantly correlated with overall survival (All P value <0.05). Multivariate analysis showed that CA125 ≥30 IU/ml ( OR=2.669, P=0.001), microvascular invasion ( OR=1.736, P=0.028), poor tumor differentiation ( OR=1.604, P=0.027), adjuvant chemotherapy ( OR=0.439, P<0.001), initial recurrence site (All P value <0.05) were the independent risk factors for overall survival. The median recurrence-free survival of 172 patients was 9 months (95% CI 7.075-10.925). Univariate analysis showed that CA125, tumor size, lymph node metastasis and microvascular invasion were significantly correlated with recurrence-free survival (All P value <0.05). Multivariate analysis showed that CA125 ( OR=1.640, P=0.026), tumor size ( OR=1.774, P=0.011) and microvascular invasion ( OR=1.563, P=0.034) were the independent risk factors for recurrence-free survival. After surgery, the median survival time of patients with local recurrence, other pattern recurrence, abdominal or retroperitoneal metastasis, multi-site recurrence and liver metastasis was 28, 22, 21, 15 and 14 months, respectively. Among them, the overall survival of patients with postoperative local recurrence was longest, which was significantly longer than that of patients with multi-site recurrence ( P=0.035) and liver metastasis ( P=0.007); the survival of patients with abdominal or retroperitoneal metastasis was also longer than that with liver metastasis ( P=0.005); and all the differences were statistically significant. In 128 patients with recurrence, the median overall survival of 26 patients without adjuvant therapy was 10 months (95% CI 6.877-13.123); the median overall survival of 68 patients with adjuvant chemotherapy was 15 months (95% CI 13.013-16.987); the median overall survival of 34 patients with comprehensive treatment of surgery and radiotherapy was 19 months (95% CI 15.100-22.900), which was significantly higher than the other two groups, and there were significant statistical differences among the three groups ( P<0.001). Conclusions:The initial recurrence site of pancreatic cancer after radical operation is an independent risk factor for overall survival. Compared with local recurrence and abdominal or retroperitoneal metastasis, patients with multi-site recurrence and liver metastasis have a poor prognosis. Comprehensive treatment after recurrence can significantly prolong the overall survival.

Objective:To investigate the risk factors for postoperative early recurrence of patients with single large hepatocellular carcinoma (HCC) (tumor diameter≥5cm).Methods:Clinical data of 135 single large HCC patients who underwent radical resection from Jan 2015 to Sep 2020 in Ningbo Medical Centre Lihuili Hospital were analyzed.Results:Seventy-five HCC patients suffered recurrence,among those 42 patients had early recurrence(within 12 months). Multivariate analysis showed that alpha-fetoprotein (AFP)≥400 ng/ml ( OR=3.510,95% CI: 1.528-8.064; P=0.003) and tumor microvascular invasion (MVI) ( OR=2.769,95% CI: 1.143-6.706; P=0.024) were independent risk factors for early recurrence of single large hepatocellular carcinoma. Survival analysis showed that early recurrence risk factors significantly reduced recurrence free survival (RFS)(AFP≥400 ng/ml, χ 2=23.038, P<0.001; MVI positive , χ 2=10.554, P=0.001) and overall survival (OS) (AFP≥400 ng/ml, χ 2=14.336, P<0.001; MVI positive, χ 2=10.481, P=0.001) in single large hepatocellular carcinoma patients. Conclusion:AFP≥400 ng/ml and MVI positive are independent risk factors for postoperative early recurrence in single large hepatocellular carcinoma patients.

Objective To systematically evaluate the risk factors for postoperative pulmonary infection in patients with esophageal cancer. Methods CNKI, Wangfang Data, VIP, CBM, PubMed, EMbase, The Cochrane Library were searched from inception to January 2021 to collect case-control studies, cohort studies and cross-sectional studies about risk factors for postoperative pulmonary infection in patients with esophageal cancer. Two researchers independently conducted literature screening, data extraction and quality assessment. RevMan 5.3 software and Stata 15.0 software were used for meta-analysis. Results A total of 20 articles were included, covering 5 409 patients of esophageal cancer. The quality score of included studies was 6-8 points. Meta-analysis results showed that age (MD=1.99, 95%CI 0.10 to 3.88, P=0.04), age≥60 years (OR=2.68, 95%CI 1.46 to 4.91, P=0.001), smoking history (OR=2.41, 95%CI 1.77 to 3.28, P<0.001), diabetes (OR=2.30, 95%CI 1.90 to 2.77, P<0.001), chronic obstructive pulmonary disease (OR=3.69, 95%CI 2.09 to 6.52, P<0.001), pulmonary disease (OR=2.22, 95%CI 1.16 to 4.26, P=0.02), thoracotomy (OR=1.77, 95%CI 1.32 to 2.37, P<0.001), operation time (MD=14.08, 95%CI 9.64 to 18.52, P<0.001), operation time>4 h (OR=3.09, 95%CI 1.46 to 6.55, P=0.003), single lung ventilation (OR=3.46, 95%CI 1.61 to 7.44, P=0.001), recurrent laryngeal nerve injury (OR=5.66, 95%CI 1.63 to 19.71, P=0.006), and no use of patient-controlled epidural analgesia (PCEA) (OR=2.81, 95%CI 1.71 to 4.61, P<0.001) were risk factors for postoperative pulmonary infection in patients with esophageal cancer. Conclusion The existing evidence shows that age, age≥60 years, smoking history, diabetes, chronic obstructive pulmonary disease, pulmonary disease, thoracotomy, operation time, operation time>4 h, single lung ventilation, recurrent laryngeal nerve injury, and no use of PCEA are risk factors for postoperative pulmonary infection in patients with esophageal cancer. Due to the limitation of the quantity and quality of included literature, the conclusion of this study still needs to be confirmed by more high-quality studies.
