ObjectiveTo summarize the experience of diagnosis and treatment of pancreatic cystic neoplasms (PCN).MethodThe general information, imaging findings, preoperative blood biochemical indexes, tumor markers, operation related data, postoperative complications, and pathological results of patients with PCN confirmed by pathological examination in Affiliated Hospital of Xuzhou Medical University from January 1, 2014 to December 31, 2019 were retrospectively analyzed.ResultsAmong the 158 patients who underwent surgical resection, the male to female ratio was 1∶1.6, and the median age was 56.2 years (range 26 to 82 years). Serous cystadenoma (SCN) was the most common, accounting for 34.2% (n=54), followed by mucinous cystadenoma (MCN) and intraductal papillary mucinous neoplasm (IPMN), accounting for 26.6% (n=42) and 20.2% (n=32). The proportion of solid pseudopapillary tumor (SPT) was the smallest, which was 19.0% (n=30). The PCN malignant rate was 19.0% (n=30), with the highest malignant rate being IPMN (43.8%, n=14), and the lowest being SCN (3.7%, n=2). Patients with PCN malignant group had significantly higher serum CA19-9, CEA, CA125, and neutrophil/lymphocyte ratio (NLR) than those in the benign group（all P<0.05）. The preoperative diagnosis of PCN was ambiguous, and the rate of misdiagnosis was high. The correct diagnosis rate of accurate preoperative specific classification was only 31.6% (n=50), and the lowest SCN (14.8%, n=8). High CA19-9, high NLR value, tumor location in the head/neck of pancreas and enhanced solid component were independent predictors of malignant PCN (P<0.05).ConclusionImproving the preoperative diagnosis ability of PCN and accurately determining the PCN classification before operation are helpful for the standardized treatment of PCN.
Objective To explore the influencing factors for early complications after laparoscopic sleeve gastrectomy (LSG). Methods A retrospective analysis was conducted for the clinical data of 306 obese patients undergoing LSG at the Weight Reduction and Metabolism Center of Xuzhou Medical University Affiliated Hospital of Lianyungang from January 2020 to September 2022. Early postoperative complications (≤30 d) of LSG were classified according to the Clavien-Dindo classification, and the influencing factors of early postoperative complications were explored. Results There were 27 cases (8.8%) suffered from early complications, including 8 cases of grade Ⅰ (2.6%), 15 cases of grade Ⅱ (4.9%), 4 cases of grade Ⅲ (1.3%), there were no grade Ⅳ and grade Ⅴ complications. The multivariate results showed that BMI≥45 kg/m2 [OR=3.63, 95%CI (1.10, 11.92)], high cholesterol [OR=7.12, 95%CI (2.42, 20.95)], and preoperative GERD [OR=3.69, 95%CI (1.11, 12.23)] were influencing factors for early complications. Conclusions LSG is a safe diagnostic and therapeutic method for treating obesity. Attention should be paid to the impact of BMI, high cholesterol, and preoperative GERD on the occurrence of complications after LSG.
ObjectiveTo explore the risk factors of lymph node metastasis (LNM) in patients with early gastric cancer (EGC), and try to establish a risk prediction model for LNM of EGC.MethodsThe clinicopathologic data of EGC patients who underwent radical gastrectomy and lymph node dissection from January 1, 2015 to December 31, 2019 in this hospital were retrospectively analyzed. Univariate analysis and logistic regression analysis were used to determine the risk factors for LNM of EGC, and the risk prediction model for LNM of EGC was established based on the multivariate results.ResultsA total of 311 cases of EGC were included in this study, and 60 (19.3%) cases had LNM. Univariate and multivariate analysis showed that age (younger), depth of tumor invasion (submucosa), vascular invasion, and undifferentiated carcinoma were the risk factors for LNM of EGC (P<0.05). The optimal threshold for predicting LNM of EGC was 0.158 (area under the receiver operating characteristic curve was 0.864), the sensitivity was 80.0%, and the specificity was 79.3%.ConclusionsFrom results of this study, risk factors for LNM of EGC have age, depth of invasion, vascular invasion, and differentiation degree. Risk prediction model for LNM of EGC established on this results has high sensitivity and specificity, which could provide some references for treatment strategy of EGC.
ObjectiveTo explore feasibility and safety of π-shaped esophagojejunal anastomosis in totally laparoscopic total gastrectomy (TLTG).MethodThe clinical data of 20 patients who underwent TLTG, admitted in the Affiliated Hospital of Xuzhou Medical University from January 2018 to December 2018 were retrospectively analyzed.ResultsTLTG with π-shaped esophagojejunal anastomosis was successfully carried out in all 20 patients. The operative time was (236.0±55.5) min, the π-shaped esophagojejunal anastomosis time was (25.7±4.8) min, the intraoperative blood loss was (192.0±148.9) mL, the operative incision length was (3.7±0.8) cm. The postoperative pain score was 2.4±1.1, the first flatus time was (3.1±0.9) d, the first postoperative ambulation time was (1.8±0.7) d, the removal time of nasoenteral nutrution tube was (7.4±2.4) d, the liquid diet time was (6.2±1.4) d, the removal time of intraoabdominal drainage tube was (7.8±2.8) d, the postoperative hospital stay was (10.8±3.0) d. There was no death related to the anastomosis in all patients. Two patients developed a little pleural effusion and 1 patient developed lymphatic leakage were cured with conservative treatment. One patient with intraabdominal encapsulated effusion was cured by puncture and drainage treating. There was no postive incisal margin. The length of upper segment of resection form gastric cancer was (2.3±1.7) cm, the maximum tumor diameter was (4.9±2.8) cm, the number of dissected lymph nodes was 27.9±5.6. All patients were followed up 3–15 months. Eight patients underwent endoscopic examination had no obvious anastomosis stenosis and esophageal reflux. Two patients died of tumor recurrence and metastasis witnin one year after operation, and the rest had disease-free survival until the end of follow-up.ConclusionFrom preliminary results of limited cases in this study, π-shaped esophagojejunal anastomosis in TLTG is a technically safe and feasible surgical procedure in treatment of gastric cancer.
