Objective To evaluate different clinical effects of three inflow occlusion methods in hepatectomy including pringle maneuver （Pringle group），selective portal venous exclusion （SPVE group）， and Glissonean pedicle exclusion （SGSE group）. Methods The clinical data of patients underwent the liver resection with the above liver inflow occlusion methods were retrospectively analyzed. The operation time， inflow occlusion time， amount of intraop-erative blood loss， transfusion rate， and postoperative hepatic function and complication rate were compared for each group. Results There were not significant difference of preoperative conditions，operation time， inflow occlusion time，tumor character， postoperative liver function， hospital time，and ICU time （P＞0.05）. The amount of intraoperative blood loss and rate of blood transfusion of SGSE group were significantly less （lower） than those Pringle group and SPVEgroup （P＜0.05）. In addition to the first day after operation， the AST and ALT at other time point of SPVE group and SGSE group were improved than that Pringle group （P＜0.05）， while TBIL at the third and fifth day after operation ofPringle group were improved （P＜0.05）. The complication rates of SPVE group and SGSE group were significantly lowerthan that of Pringle group （P＜0.05）. Conclusions In the similar operatin time and inflow occlusion time，Glissonean pedicle exclusion method can control the intraoperative blood loss and blood transfusion better，and can promote the patientrecovery. Besides， the inflow occlusion methods should be selected based on the practical condition of patients.
Objective To review recent advancement of the relationship between obesity and gastric cancer. Method We searched PubMed, Medline, EMBASE, Cochrane Library databases, CNKI, and WanFang database for recent clinical trials about the impact of obesity on occurrence, surgery outcomes, and prognosis of gastric cancer. Results Obesity significantly increased the risk of adenocarcinoma of esophagogastric junction (AEG), increased difficulty in radical operation of gastric cancer and complications of perioperative period, but it had no effect on the long-term operative outcomes. The association between obesity and the survival of gastric cancer was not clear. However, the better survival was observed in most researches of gastric cancer patients with excess body weight. Conclusions The relationship between obesity and gastric cancer is very complex, and there is no consistent conclusion. A reasonable body weight by a healthy lifestyle is expected to decline the incidence of AEG.
ObjectiveTo systematically evaluate the effect of single-port totally extraperitoneal (SPTEP) and conventional totally extraperitoneal (CTEP) inguinal hernia repair in treatment of inguinal hernia. MethodsPubMed, Cochrane Library, Embase, WanFang Data, VIP, and CNKI databases were electronically searched and the randomized controlled trial (RCT) and non-RCT studies on the efficacy and safety of SPTEP versus CTEP for patients with inguinal hernia from January 2010 to November 2019 were collected. Two reviewers independently screened literatures, extracted data, and assessed risk of bias of included studies, then the meta-analysis was performed by using RevMan5.3 software. ResultsA total of 17 clinical studies were included in the analysis, with 1 106 cases in the SPTEP group and 966 cases in the CTEP group. The results of meta-analysis showed that: the hospital stay [SMD=–0.12, 95%CI (–0.22, –0.02), P=0.01] and the time to resume normal activity [SMD=–1.17, 95%CI (–2.10, –0.23), P=0.01] were shorter, the satisfaction score of incision scars [SMD=0.92, 95%CI (0.31, 1.53), P<0.01] was higher in the SPTEP group as compared with the CTEP group. However, the operative time of SPTEP group was longer than that of the CTEP group both for unilateral inguinal hernia [MD=4.08, 95%CI (0.34, 7.83), P=0.03] and bilateral inguinal hernia [MD=5.53, 95%CI (0.39, 10.68), P=0.04]. There were no statistical differences in the postoperative pain score (24 h and 7 d), incidence of postoperative complications, the rate of patients satisfied with the incision, and hospitalization costs between the two groups (P>0.05). ConclusionsFrom the results of this meta-analysis, SPTEP has some certain advantages in shortening hospital stay and returning to normal activity time, and improving incision satisfaction. However, compared with CTEP, mean operative time of SPTEP is longer. Although SPTEP has developed for several years, it is difficult to replace CTEP.
