ObjectivesTo evaluate the clinical value of laparoscopic exploration in the diagnosis of tuberculous peritonitis by meta-analysis.MethodsThe Cochrane Library, PubMed, Web of Science, WanFang Data, CNKI and VIP databases were electronically searched to collect relevant studies on the diagnostic value of laparoscopic exploration in diagnosing tuberculous peritonitis from January 1st, 1990 to April 1st, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. The Rveman 5.3, Meta-DiSc 1.4 and Stata SE15 software were used for statistical analysis and the receiver operating characteristic curve (SROC) was drawn.ResultsA total of 10 studies involving 1098 patients were included. The results of meta-analysis showed that the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnosis odds ratio and area under the curve of SROC were 0.98 (95%CI 0.96 to 0.98), 0.85 (95%CI 0.78 to 0.91), 4.78 (95%CI 1.98 to 11.54), 0.06 (95%CI 0.03 to 0.12), 111.40 (95%CI 36.55 to 339.58) and 0.971 1, respectively and the Q* was 0.9216.ConclusionsThe existing evidence shows that laparoscopic exploration has higher sensitivity and specificity in the diagnosis of tuberculous peritonitis. Laparoscopic exploration can be used as a diagnosis and treatment tool for patients with tuberculous peritonitis in case the laboratory test cannot determine the origin. Due to the limited quality and quantity of included studies, the above results should be validated by more studies.
ObjectiveTo evaluate clinical feasibility and safety of total laparoscopic pancreaticoduodenectomy (TLPD).MethodThe clinical data of 51 consecutive cases who underwent TLPD, admitted in this department of pancreatic surgery of the Affiliated Hospital of Xuzhou Medical University from August 2016 to August 2018, were analyzed retrospectively.ResultsThe TLPDs were successfully completed in the 51 patients. The operative time was (375.5±75.2) min, the pancreaticojejunostomy time was (45.2±8.3) min and bilioenteric anastomosis time was (25.6±7.5) min. The intraoperative blood loss was (337.8±164.4) mL. The length of surgical incision was (6.0±1.2) cm. The duration of flatulence was (3.5±1.0) d. The time for liquid diet was (5.2±2.1) d, the postoperative first ambulation time was (2.0±1.2) d. The duration of postoperative hospital stay was (14.8±5.3) d. The total postoperative complication rate was 34.3% (17/51), with 19.6% (10/51) of B or C postoperative pancreatic fistula and 9.8% (5/51) of bleeding. The postoperative pathology showed that there were 45 cases of malignant tumor and there was no positive incisal margin. The maximum tumor size was (2.8±1.2) cm and the number of lymph nodes harvested was 12.6±7.8. All the patients were followed up for 2–24 months with a median time of 17 months. The 1-year overall survival rate and progression-free survival rate of the patients with malignant tumors were 84.4% (38/45) and 77.8% (35/45), respectively.ConclusionTLPD is safe and feasible in cases of clinical practice under skilled hand and there are advantages such as faster postoperative recovery and shorter hospital stay.
ObjectiveTo explore the feasibility and application value of laparoscopic pancreaticoduodenectomy (LPD) in elderly patients.MethodsThe clinical data of patients who underwent LPD from August 2016 to July 2019 were retrospectively analyzed. The patients were allocated into the elderly group (≥65 years old) and non-elderly group (<65 years old). The early surgical outcomes and postoperative complications of the two groups were compared.ResultsIn this study, 69 cases of LPD were collected, including 42 cases in the elderly group and 27 cases in the non-elderly group. Compared with the non-elderly group, the proportion of patients complicated comorbidities was higher (P<0.05), albumin level was lower (P<0.05), and American Society of Anesthesiologists classification was higher (P<0.05) in the elderly group. There were no significant differences in the intraoperative conditions, postoperative recovery, and postoperative complications between the two groups (P>0.05), and there were no significant differences in the pathological results of postoperative malignant tumor between the two groups (P>0.05).ConclusionsFor elderly patients with over 65 years old, LPD is a safe and feasible surgical procedure for clinical practice. Meanwhile, early surgical outcomes are satisfactory, postoperative complications are not increased, and tumor cure effect can be achieved.
ObjectiveTo observe expressions of E3 ubiquitin ligase—mitsugmin53 (MG53) protein, MG53 mRNA, and insulin receptor substrate 1 (IRS-1) mRNA in skeletal muscle of non-obese type 2 diabetic mellitus (T2DM) rats after gastric bypass operation (GBP), and to investigate possible mechanism of GBP in improving insulin resistance.MethodsTwenty-four healthy male GK rats were randomly divided into diabetic operation group, diabetic sham operation group, and diabetic control group, 8 rats in each group; besides, 8 male Wistar rats were served as normal control group. The expressions of MG53 protein in skeletal muscle tissue were detected by using Western blot method on week8 after operation. The mRNA levels of IRS-1 and MG53 in skeletal muscles tissue were measured by RT-PCR methods on week 8 after operation.Results① The expressions of MG53 protein and MG53 mRNA in the diabetic sham operation group and diabetic control group were significantly higher than those in the diabetic operation group and the normal control group on week 8 after operation (P<0.05), respectively, which had no significant differences between the diabetic operation group and the normal control group (P>0.05), and between the diabetic sham operation group and the diabetic control group (P>0.05) on week 8 after surgery. ② Compared with the normal control group, the expression of IRS-1 mRNA was significantly decreased in the diabetic operation group, the diabetic sham operation group, and the diabetic control group (P<0.05), while there were no significant differences between the diabetic operation group, diabetic sham operation group, and the diabetic control group on week 8 after operation (P>0.05).ConclusionExpression of E3 ubiquitin ligase—MG53 protein in skeletal muscle tissue in T2DM rats following GBP is decreased, thus reduces the IRS-1 ubiquitin-degradation, increase the expression of IRS-1 protein in insulin signaling pathway of skeletal muscle tissue, and improve insulin resistance of skeletal muscle.
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.
