Objective:To investigate the efficacy of anaplastic lymphoma kinase-tyrosine kinase inhibitors (ALK-TKI) in treatment of inflammatory myofibroblastic tumor (IMT).Methods:The clinicopathological data of one recurrent abdominal IMT patient in Renmin Hospital of Wuhan University in 2018 were retrospectively analyzed. The clinicopathological and molecular characteristics, ALK-TKI treatment efficacy and prognosis of 41 patients with IMT reported in the literature from January 2010 to August 2020 were systematically reviewed.Results:This patient with abdominal IMT in Renmin Hospital of Wuhan University was a 27-year-old female who relapsed 2 months after surgery. Chemotherapy combined with bevacizumab was ineffective. After oral administration of crizotinib, the condition resolved after 1 month, and complete remission (CR) was achieved after 29 months. The median age of onset of 41 IMT cases reported in the literature was 22 years old (0-61 years old), of which 32 cases (78.0%) had multiple organ involvement, all of which had recurrence or metastasis. There were 38 cases of ALK mutation and 3 cases of TFG-ROS1 fusion gene-positive. Thirty-four patients treated with crizotinib in the first-line treatment of ALK-TKI, and the median resistance time of crizotinib was 8 months (2-48 months). The total clinical benefit rate of ALK-TKI was 85.3% (29/34), and 20 patients achieved CR. The median time for the first CR was 11 months (4-36 months), and the median duration time of medication for CR patients was 19.5 months (2-60 months). The median progression-free survival (PFS) time of 24 patients who underwent surgery and/or chemotherapy and radiotherapy was 4 months (1-45 months); after progression, ALK-TKI treatment was performed, and the median PFS time was 14 months (3-62 months).Conclusions:IMT is a true neoplasm with characteristics of recurrence and metastasis. Reasonable combination of ALK-TKI with surgery, radiotherapy and chemotherapy can improve the prognosis of IMT patients.

Objective:To investigate the influencing factors of surgical site infection (SSI) after abdominal surgery.Methods:The retrospective cross-sectional study was conducted. The clinical data of 567 patients undergoing abdominal surgery in 6 medical centers, including 445 cases in the Zhengzhou Central Hospital Affiliated to Zhengzhou University, 54 cases in the the First Affiliated Hospital of Zhengzhou University, 49 cases in the Shangqiu First People's Hospital, 10 cases in the Luoyang Central Hospital, 5 cases in the First Affiliated Hospital of Henan University of Science and Technology and 4 cases in the Henan Provincial People's Hospital, from June 1 to June 30, 2020 were collected. There were 284 males and 283 females, aged (51±18)years. Observation indicators: (1) incidence of SSI after surgery; (2) influencing factors of SSI. Follow-up was conducted using outpatient examination and telephone interview to detect the incidence of SSI. Patients without implant were followed up within postoperative 30 days, and patients with implant were followed up within postoperative 1 year. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measure-ment data with skewed distribution 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 performed using the chi-square test or Fisher exact probability. Univariate analysis was performed using the corresponding statistical methods. Multivariate analysis was performed using the Logistic stepwise regression model advance method. Results:(1) Incidence of SSI after surgery. All the 567 patients were followed up after surgery as planned. There were 27 cases with SSI after surgery including 9 cases with superficial incision infection, 9 cases with deep incision infection, 9 cases with organ/gap infection. Of the 27 cases with SSI after surgery, 18 cases with positive results of incisional microbial culture including 8 cases with positive results of Escherichia coli, 6 cases with positive results of Klebsiella pneumonia, 3 cases with positive results of Enterococcus faecium and 1 case with positive result of Pseudomonas aeruginosa. (2) Influencing factors of SSI. Results of univariate analysis showed that age, preoperative hemoglo-bin, preoperative albumin, preoperative fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site, surgical incision type, duration of intensive cure unite, duration of post-operative hospital stay, duration of total hospital stay, operation time, hospital expense were related factors affecting the incidence of SSI of patients undergoing abdominal surgery ( χ2=40.12, Z=?4.22, ?2.21, ?4.75, χ2=7.07, 16.43, 38.06, 17.50, Z=?4.43, ?4.42, ?7.14, ?7.15, ?5.90, P<0.05) and the American Association of Anesthesiologists Classification, preoperative oral antibiotics, surgical methods and postoperative intensive care unit stay were related factors affecting the incidence of SSI of patients undergoing abdominal surgery ( P<0.05). Results of multivariate analysis showed that age, preopera-tive fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site as appendix and rectum, surgical methods, surgical incision type as infective incision and polluted incision, operation time were independent factors affecting the incidence of SSI of patients undergoing abdo-minal surgery ( odds ratio=7.69, 1.21, 0.27, 5.82, 5.19, 19.08, 0.23, 27.76, 4.97, 1.01, 95% confidence intervals as 2.04?28.95, 1.04?1.41, 0.08?0.94, 1.36?24.85, 1.10?24.43, 4.48?81.25, 0.06?0.87, 2.54?303.53, 1.12?22.14, 1.01?1.02, P<0.05). Conclusion:Age, preoperative fasting blood glucose, preoperative intestinal preparation, surgical type, surgical site as appendix and rectum, surgical methods, surgical incision type as infective incision and polluted incision, operation time are independent factors affecting the incidence of SSI of patients undergoing abdominal surgery.

OBJECTIVE:
To determine the incidence of surgical site infection (SSI) after abdominal surgery and to further evaluate the related risk factors of SSI in China.
METHODS:
The multicenter cross-sectional study collected clinical data of all adult patients who underwent abdominal surgery from May 1, 2018 to May 31, 2018 in 30 domestic hospitals, including basic information, perioperative parameters, and incisional microbial culture results. The primary outcome was the incidence of SSI within postoperative 30 days. SSI was classified into superficial incision infection, deep incision infection, and organ/gap infection according to the US Centers for Disease Control and Prevention (CDC) criteria. The secondary outcome variables were ICU stay, postoperative hospital stay, total hospital stay, 30-day mortality and treatment costs. Multivariate logistic regression was used to analyze the risk factors of SSI.
RESULTS:
A total of 1666 patients were enrolled in the study, including 263 cases of East War Zone Hospital of PLA, 140 cases of Affiliated Hospital of Qingdao University, 108 cases of The First Affiliated Hospital of Nanchang University, 87 cases of Central War Zone Hospital of PLA, 77 cases of West China Hospital, 74 cases of Guangdong General Hospital, 71 cases of Chenzhou First People's Hospital, 71 cases of Zigong First People's Hospital, 64 cases of Zhangjiagang First People's Hospital, 56 cases of Nanyang City Central Hospital, 56 cases of Lanzhou General Hospital of Lanzhou Military Command, 56 cases of Shandong Provincial Hospital, 52 cases of Shangqiu First People's Hospital, 52 cases of People's Hospital of Xinjiang Uygur Autonomous Region, 48 cases of The Second Xiangya Hospital of Central South University, 48 cases of Chinese PLA General Hospital, 44 cases of Affiliated Hospital of Xuzhou Medical University, 38 cases of Hunan Province People's Hospital, 36 cases of Dongguan Kanghua Hospital, 30 cases of Shaoxing Central Hospital, 30 cases of Northern Jiangsu People's Hospital, 29 vases of The First Affiliated Hospital of Zhengzhou University, 27 cases of General Hospital of Tianjin Medical University, 22 cases of Zigong Fourth People's Hospital, 21 cases of The Second Hospital of University of South China, 18 cases of Tongji Hospital, 15 cases of Nanchong Central Hospital, 12 cases of The 901th Hospital of PLA, 11 cases of Hunan Cancer Hospital, 10 cases of Lanzhou University Second Hospital. There were 1019 males and 647 females with mean age of (56.5±15.3) years old. SSI occurred in 80 patients (4.8%) after operation, including 39 cases of superficial incision infection, 16 cases of deep incision infection, and 25 cases of organ/interstitial infection. Escherichia coli was the main pathogen of SSI, and the positive rate was 32.5% (26/80). Compared with patients without SSI, those with SSI had significantly higher ICU occupancy rate [38.8%(31/80) vs. 13.9%(220/1586), P<0.001], postoperative hospital stay (median 17 days vs. 7 days, P<0.001) and total hospital stay (median 22 days vs. 13 days, P<0.001), and significantly higher cost of treatment (median 75 000 yuan vs. 44 000 yuan, P<0.001). Multivariate analysis showed that male rise(OR=2.110, 95%CI:1.175-3.791, P=0.012), preoperative blood glucose level rise(OR=1.100, 95%CI: 1.012-1.197, P=0.026), operative time (OR=1.006, 95%CI:1.003-1.009, P<0.001) and surgical incision grade (clean-contaminated incision:OR=10.207, 95%CI:1.369-76.120, P=0.023; contaminated incision: OR=10.617, 95%CI:1.298-86.865, P=0.028; infection incision: OR=20.173, 95%CI:1.768-230.121, P=0.016) were risk factors for SSI; and laparoscopic surgery (OR=0.348, 95%CI:0.192-0.631, P=0.001) and mechanical bowel preparation(OR=0.441,95%CI:0.221-0.879, P=0.020) were protective factors for SSI.
CONCLUSIONS
The incidence of postoperative SSI in patients with abdominal surgery in China is 4.8%. SSI can significantly increase the medical burden of patients. Preoperative control of blood glucose and mechanical bowel preparation are important measures to prevent SSI.
