With the upgrading of minimally invasive surgical concepts and laparoscopic equipment for gastric cancer, single-incision laparoscopic surgery (SILS) had emerged as a new focus of research in gastric cancer surgery. SILS offered advantages such as reduced damage, superior cosmetic outcomes, decreased postoperative pain, and faster recovery as compared with traditional laparoscopic gastrectomy. However, its level of difficulty limited its further promotion and application. Although numerous studies supported the safety and feasibility of SILS, more high-level evidence-based medical research was required to endorse its widespread use. The author reviewed the development history, current status, and prospects of SILS laparoscopic gastric cancer surgery.
ObjectiveTo explore technical essentials and safety of laparoscopic cholecystectomy (LC) guided by gallbladder ampulla localization on an imaginary clock for cholecystitis.MethodsA retrospective study of 8 707 continuous patients with mild cholecystitis who underwent LC from July 1998 to February 2018 at a single institution was conducted. Among them, 3 168 patients were treated by the traditional LC from July 1998 to February 2007 (a traditional LC group), 5 539 patients were treated by the LC with the guidance of the gallbladder ampulla localization on an imaginary clock from March 2007 to February 2018 (a gallbladder ampulla localization group). The conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury, operative time, intraoperative blood loss, and postoperative hospital stays were compared between the traditional LC group and the gallbladder ampulla localization group.ResultsThere were no significant differences in the gender, age, course of disease, and type of cholecystitis between these two groups (P>0.050). The rates of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury and the operative time, intraoperative blood loss and postoperative hospital stays in the traditional LC group were 3.00% (95/3 168), 0.13% (4/3 168), 0.09% (3/3 168), 0.03% (1/3 168), (43.6±12.6) min, (18.7±3.3) mL, (3.6±2.7) d, respectively, which in the gallbladder ampulla localization group were 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), (32.2±10.5) min, (12.4±3.5) mL, (3.5±2.8) d, respectively. The differences of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding rates, and the operative time and intraoperative blood loss were statistically significant between these two groups (P<0.050). The differences of the bile leakage without bile duct injury rate and postoperative hospital stays were not statistically significant between the two groups (P>0.050).ConclusionThis study shows that gallbladder ampulla localization on an imaginary clock is useful for ductal identification so as to reduce bile duct injury and improve safety of LC in case of no conversion to open surgery.
Objective To explore application value of three-dimensional (3D) laparoscopic visualization during bariatric surgery. Methods From January 2015 to May 2017, 64 patients underwent laparoscopic bariatric surgery in our department were included. Among these cases, 19 patients underwent 3D laparoscopic sleeve gastrectomy, and 21 patients underwent two-dimensional (2D) laparoscopic sleeve gastrectomy. Thirteen patients underwent 3D laparoscopic Roux-en-Y gastric bypass, and 11 patients underwent 2D laparoscopic Roux-en-Y gastric bypass. The total operative time, the digestive tract reconstruction time, the intraoperative blood loss, the postoperative hospitalization stay, and the operative complications were analyzed statistically. Results The laparoscopic bariatric surgery were performed successfully in all the 64 patients, no case was converted to the laparotomy, and no 3D laparoscopy was converted to the 2D laparoscopy. The suture time of the gastric incisal margin was shorter and the intraoperative blood loss was less with the 3D laparoscopic sleeve gastrectomy as compared with the 2D laparoscopic sleeve gastrectomy (P<0.05), but the total operative time and the postoperative hospitalization stay had no significant differences and none of postoperative complications happened between these two modes (P>0.05). The total operative time, the time to make gastric pouch, the time of the gastro-jejunal anastomosis or jejunum-jejunum anastomosis, and the intraoperative blood loss with the 3D laparoscopic Roux-en-Y gastric bypass were significantly less than those with the 2D laparoscopic Roux-en-Y gastric bypass (P<0.05), but the postoperative hospitalization stay had no significant difference between these two modes (P>0.05). Conclusion Pre-liminary results of limited cases in this study shows that 3D laparoscope could provide 3D stereoscopic visualization, which facilitateto clearly identify anatomical structures, and be helpful to complex operations, and then might reduce operating time, both physicians and patients could benefit from it.
ObjectiveTo compare the efficacy of totally transanal endorectal pull-through and laparoscopic assistance endorectal pull-through in the treatment of Hirschsprung’s disease (HD).MethodsPubMed, EMBASE, The Cochrane Library, CNKI, Wanfang, and VIP Database were searched to screen out the comparative studies published between January 1998 and May 2020 on the treatment of HD with totally transanal endorectal pull-through and laparoscopic assistance endorectal pull-through. Then two reviewers independently completed the literatures screening, data extraction, and quality evaluation. The Review Manager 5.3 software was used to combine the effect size of the postoperative effect indicators included in the literatures. Stata 14.0 software was used to perform Begg’s and Egger’s tests on the publication bias of the included literatures.ResultsA total of 8 clinical studies conforming to the standards were included and 702 cases of children undergoing HD radical resection were recorded, including 335 cases in the totally transanal endorectal pull-through group and 367 cases in the laparoscopic assistance endorectal pull-through group. Compared with the laparoscopic assistance endorectal pull-through group, the totally transanal endorectal pull-through group had an advantage in the incidence of postoperative faecal incontinence/soiling [OR=0.20, 95%CI was (0.07, 0.54), P=0.001], and the postoperative constipation recurrence rate was higher than the laparoscopic assistance endorectal pull-through group [OR=2.39, 95%CI was (1.05, 5.42), P=0.04]. There were no statistically significant differences between the two groups in terms of postoperative enterocolitis [OR=1.01, 95%CI was (0.59, 1.75), P=0.96], postoperative adhesion intestinal obstruction [OR=0.74, 95%CI was (0.28, 1.95), P=0.54], and postoperative anastomotic stenosis [OR=1.14, 95%CI was (0.51, 2.56), P=0.74].ConclusionsCompared with laparoscopic assistance endorectal pull-through, the totally transanal endorectal pull-through can reduce the incidence of postoperative faecal incontinence/soiling, but the rate of recurrence of postoperative constipation is higher. The two surgical procedures for HD have similar incidences of postoperative enterocolitis, anastomotic stenosis, and adhesive intestinal obstruction.
Objective To compare efficacy of laparoscopic and open duodenal circular drainage operation for superior mesenteric artery compressing syndrome (SMACS). Methods From December 2012 to December 2015, the clinical data of 23 cases of laparoscopic duodenal circular drainage operation (laparoscope group) and 28 cases of open duodenal circular drainage operation (open group) were analyzed. The operation time, intraoperative bleeding, postoperative ambulation time, postoperative analgesics usage, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time and postoperative incidence of complications were compared. The patients were followed up to confirm the effect after the operation. Results There were no differences of the age, sex, and body weight index between the laparoscope group and the open group (P>0.05). The operation time had no significant difference between these two groups (P>0.05). Compared with the open group, the intraoperative bleeding was less (P<0.05), the postoperative ambulation time, postoperative the first exhaust time, postoperative the first feeding time, postoperative hospitalization time were shorter (P<0.05), the rates of postoperative analgesics usage, incision infection, pulmonary infection, and intestinal obstruction were lower (P<0.05) in the laparoscope group. The rates of anastomotic leakage and anastomotic bleeding, and total postoperative complications rate had no significant differences between these two groups (P>0.05). All the patients were followed up for 8–36 months. The clinical symptoms disappeared and the body weight increased to normal level in the two groups. Conclusions Preliminary results of in this study show that laparoscopic duodenal circular drainage operation in treatment of SMACS has some advantages such as less trauma, faster recovery, fewer complications and shorter hospitalization time. Laparoscopy will be an ideal choice for treatment of SMACS.

Objective To investigate effects of fast track surgery (FTS) combined with laparoscopy on perioperative inflammatory mediators, immune indices, and clinical short-term recovery effect in patient with colorectal cancer. Methods A prospective randomized controlled trial was conducted. The patients underwent laparoscopic colorectal cancer surgery at the Department of Gastrointestinal Surgery, The Third People’s Hospital of Chengdu from July 2014 to March 2017 were included in this study. The patients were randomly divided into FTS group and traditional group by the random digital table. The FTS mode and the traditional method were adopted during the perioperative period in the FTS group and the traditional group respectively. The inflammatory mediators such asC reactive protein (CRP) and interleukin 6 (IL-6) and cellular immune indexes such as CD4, CD8 and CD4/CD8 on the preoperative 1 d, postoperative 1 d, 3 d and 7 d, as well as the index of clinical short-term rehabilitation were compared between these 2 groups. Results ① Eighty-four patients were included in this study, there were 43 patients in the FTS group and 41 patients in the traditional group. There were no significant differences in the baseline characteristics and the surgical-related indicators between the two groups (P>0.050). ② There were no significant difference in the levels of CRP and IL-6 between the two groups at different time points (P>0.050). The change trend of CRP and IL-6 levels in FTS group and traditional group before and after operation were the same, the CRP and IL-6 levels at the first day after operation were significantly higher than those on 1 d before operation (P<0.001), but on the 7th day after operation decreased significantly. ③ There were no significant difference of CD4, CD 8 and CD4/CD8 levels between the two groups at different time points (P>0.050). The CD4 decreased significantly in 2 groups at the first day after operation (P<0.050), it began to rise on the 3rd day after operation and was close to the preoperative level on the 7th day after operation, but the increase in the traditional group was smaller. The changes of CD8 level at different time points before and after operation were not significant in two groups (P>0.050). The changes of CD4/CD8 ratio at different time points before and after operation were not significant in two groups (P>0.050), only the first day after operation of FTS group was significantly lower than that in preoperative 1 d (P<0.001), and on the third day after operation, it increased significantly and was close to the level of 1 day before operation. ④ The time of the first postoperative anal exhaustion or defecation in the FTS group was significantly shorter than that in the traditional group (P<0.001). The overall incidence of postoperative complications and the incidence of hypoproteinemia in the FTS group were significantly lower than those in the traditional group (P<0.050). Conclusion Compared with traditional perioperative management in combination with laparoscopic surgery, FTS combined with laparoscopic surgery has no effects on postoperative inflammatory mediators and immune parameters in patient with colorectal cancer, and it could reduce complications, reduce traumatic stress, and accelerate postoperative recovery for patient with colorectal cancer.
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.
