【Abstract】Objective To investigate prophylactic measures for nontraumatic complications of laparoscopic cholecystectomy (LC).Methods The data of 13 000 patients who underwent LC in Kunming general hospital of PLA over 13 years(1991-2004) were retrospectively reviewed. Results Nine malignant tumors and 47 common bile duct stones were missed at LC. The 9 malignant tumors included hepatic cancer (n=1), gastric cancer (n=1), gallbladder cancer (n=2), pancreatic cancer (n=2) and right colon cancer (n=3). Of all the carcinomas, 3 patients with right colon cancer underwent colectomy, the other 6 patients couldn’t be cured radically. All the 47 patients with choledocholithiasis were cured successfully, among them 31 patients were performed with ERCP and 16 were reoperated on with cholangiotomy. Conclusion This study emphasizes the necessity to analyze carefully patients’ symptoms before operation and pay attention to pathological changes of gallbladder and intraabdominal situation intraoperatively. If necessary, laparoscopic ultrosonography can be used to avoid missing malignant tumors and biliary stones.
Objectives To investigate the diagnosis and laparoscopic surgical treatment methods of calculus of cystic duct.
MethodsThe clinical data of 147 patients with calculus of cystic duct underwent laparoscopic cholecystectomy (LC) in the Second Affiliated Hospital of Wenzhou Medical College from June 2008 to June 2013 were analyzed retrospectively.
ResultsAmong the 147 patients with calculus of cystic duct, 19 cases were given preoperative diagnosis by B-ultrasound and CT scanning, 128 cases were found by exploration in operation; 146 cases underwent LC successfully and 1 case was converted to laparotomy.The 147 cases were followed-up for 3 months to 2 years with an average of 7 months and all cases were out of bile duct injury, hemorrhage, bile leakage, residual calculi or other complications.
ConclusionsPreoperative diagnosis of calculus of cystic duct is difficult, meanwhile, routine intraoperative probe is very necessary for the diagnosis of calculus of cystic duct.Proficiency in surgical technique with laparoscopic treatment of calculus of cystic duct is the key to the success of LC.
ObjectiveTo systematically review the efficacy and safety of robotic-assisted hepatectomy (RAH) versus traditional laparoscopic hepatectomy (TLH) for hepatic neoplasms.MethodsDatabases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data and CBM databases were electronically searched to collect cohort studies about the RAH vs. the TLH for liver neoplasms from inception to December 10th, 2016. Two reviewers independently screened the literatures, extracted data and assessed the risk of bias of the included studies. And finally, a meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 17 studies involving 1 389 patients were included. The meta-analysis results showed that: compared to TLH group, RAH group was associated with more estimated blood loss (WMD=39.56, 95%CI 4.65 to 74.47, P=0.013), longer operative time SMD=0.55, 95%CI 0.29 to 0.80, P<0.001), and later in the first nutritional intake time (SMD=1.06, 95%CI 0.66 to 1.45,P<0.001). However, there were no significant differences in the length of hospital stay, conversion to laparotomy, intraoperative blood transfusion, resection rate of tumor margin, complications and 90-day mortality between the two groups.ConclusionCurrent evidence indicates that TLH is superior to RAH in terms of operative time, intraoperative blood loss and the first nutritional intake time, but there are no statistically significant differences in the primary outcomes, suggesting that RAH and TLH have similar efficacy and safety for hepatic neoplasms. Due to the limitation of quality and quantity of the included studies, the above conclusions need to be verified by more high-quality research.
Objective To evaluate the clinical effectiveness of laparoscopic and open tension-free hernia repairs in adults. Methods A fully recursive literature search was conducted in PubMed (2002 to September, 2009), EMBASE (2002 to September, 2009), Cochrane Central Register of Controlled Trials (Issue 3, 2009), CBM (2002 to September, 2009) , CNKI and VIP Chinese Scientific Journals Full-text Database (2002 to September, 2009) in any language. Randomized or quasi-randomized controlled trials of inguinal hernia treated by laparoscopic and open methods in adults were considered for inclusion. The four analyzed outcome variables were chronic pain, long term recurrence, intraoperative complications and postoperative complication. Data related to clinical outcomes were extracted by two reviewers independently. Statistical analyses were carried out using RevMan 5.0 software. Results Eighteen published reports of eligible studies involving 5816 participants met the inclusion criteria. Compared with open methods, laparoscopic inguinal hernia had no significant differences in long-term recurrence rate [OR 1.53, 95%CI (1.00 to 2.34), P=0.05] and postoperative complication rate [OR 0.74, 95%CI (0.52 to 1.05), P=0.09], and had lower tendency chronic pain [OR 0.45, 95%CI (0.34 to 0.59) , Plt;0.000 01] with statistical significance. There were significant differences in intraoperative complications between the two groups [OR 2.15, 95%CI (1.32 to 3.53), P=0.002]. Conclusion Current evidence suggests that laparoscopic hernia repair is superior to open methods in chronic pain .There is no significant difference in long-term recurrence rate and postoperative complications between the two methods. More studies are needed for intraoperative complications and other long-term postoperative complications.
From December 1995 to December 1997, 1 500 patients with gallstones or together with biliary duct stones accepted laparoscopic cholesystectomy (LC) or LC+laparoscopic common bile duct exploration (LCDE). There were 9 had serious complications (0.6%) occured . While the mean age was 54.9 years old. The sex ratio (female∶male) was 1∶1.25. Three cases had major biliary duct disruption, 1 case had stomach perforation, 2 cases had duodenal injuries, 1 bleeding case because cystic artery fail to clip, 1 case had postoperative cystic duct leak, and 1 case with T-tube dislodgement. All complications had been discovered during or shortly after operations. The injuries on the extrahepatic biliary duct with lengths of 0.2-0.4cm, and the gastrodenal injuries sized 0.5-1.0cm. All of the injuries had been sutured laparoscopically without sequela. The one who had postoperative cystic duct leak and jaundice accepted LCDE, proved to have a common bile duct stone. The bleeding cystic artery had been clipped well, and the dislodged T-tube replaced well. The results show if the complications which may be very serious or complex had been discovered shortly after or during the operations, its can be managed with laparoscopic technique safely by experienced operators.
ObjectiveTo summary the standard treatment for early gastric cancer.
MethodsThe current early gastric cancer treatment guidelines around the world were analyzed and the standardized treatment patterns for early gastric cancer were concluded.
ResultsThe accurate preoperative evaluation for early gastric cancer is the basis of standardized treatment which can be divided into staging evaluation and histological evaluation.The staging evaluation is focused on the gastric wall invasion and lymph node involvement of the tumor while the histologic evaluation emphasize the histological type and grading of the tumor.According to the precise evaluation for early gastric cancer, endoscopic surgery, laparoscopic surgery, open surgery, and multimodal therapy can be applied individually to the patients.Different treatment methods have their indications, but the indications of the therapies in different guidelines are suggested with slight differences.
ConclusionIn clinical practice, the choice of treatment should be made with comprehensive consideration of diagnosis and individual characteristics of patients to achieve the most benefit on prognosis.
ObjectiveTo systematically review the influence on ovarian reserve function by different hemostatic methods during laparoscopic cystectomy in treatment of ovarian endometrioma (OE).
MethodsDatabases including The Cochrane Library, PubMed, EMbase, CNKI, CBM and WanFang Data were electronically searched, to collect relevant randomized controlled trials (RCTs) about laparoscopic electro coagulation vs. microscopically suture for OE from 1990 to Mar, 2014. Meanwhile, references of included studies were also retrieved manually. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and assessed the risk of bias of included studies. Then RevMan 5.2 software was used for meta-analysis.
ResultsA total of 16 RCTs involving 1 236 patients were finally included. The results of meta-analysis showed that the luteinizing hormone (LH) levels after 1 month, 2 months, 6 months and 12 months and estradiol (E2) levels after 2 months, 6 months had no significant differences between the two groups and the E2 level after 12 month of the suture group was significantly lower than that of the electro coagulation group. The levels of follicle stimulating hormone (FSH), LH, E2, antral follicle count (AFC), mean ovarian stromal peak systolic blood flow velocity (PSV) and anti-Mullerian hormone (AMH) in the suture group were significantly superior to those in the electro coagulation group at other follow-up time.
ConclusionCurrent evidence suggests that in treatment of ovarian endometriotic cyst by laparoscopic cystectomy, compared with electro coagulation hemostasis, suture hemostasis has less influence on ovarian reserve function. Due to limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
Objective To systematically review the efficacy of robotic, laparoscopic-assisted, and open total mesorectal excision (TME) for the treatment of rectal cancer. Methods The PubMed, EMbase, The Cochrane Library, and ClinicalTrials.gov databases were electronically searched to identify cohort studies on robotic, laparoscopic-assisted, and open TME for rectal cancer published from January 2016 to January 2022. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Subsequently, network meta-analysis was performed using RevMan 5.4 software and R software. Results A total of 24 studies involving 12 348 patients were included. The results indicated that among the three types of surgical procedures, robotic TME showed the best outcomes by shortening the length of hospital stay, reducing the incidence of postoperative anastomotic fistula and intestinal obstruction, and lowering the overall postoperative complication rate. However, differences in the number of dissected peritumoural lymph nodes were not statistically significant. Conclusion Robotic TME shows better outcomes in terms of the radicality of excision and postoperative short-term outcomes in the treatment of rectal cancer. However, clinicians should consider the patients’ actual condition for the selection of surgical methods to achieve individualised treatment for patients with rectal cancer.
ObjectiveTo study clinical value of perioperative multimodal analgesia for laparoscopic cholecystectomy based on concept of fast track surgery (FTS).
MethodsThe clinical data of 268 patients were analyzed retrospectively, who underwent laparoscopic cholecystectomy in the Department of General Surgery, the 2nd Hospital of Baiyin City from July 2013 to July 2015. All these patients were divided into FTS group and traditional group according to the chronological order, 133 patients in the traditional group were performed traditional perioperative analgesia before August 31, 2014, and 135 patients in the FTS group were performed perioperative multimodal analgesia method based on the concept of FTS after September 1, 2014. The data of both groups were collected and analyzed, including point of numerical rating scale, intestinal function recovery time, intake food time, ambulation time, drainage tube duration, postoperative hospital stay, postoperative sleep time at 72 h, and complications.
Results①The points of numerical rating scale at 1 h, 4 h, 8 h, 12 h, 24 h, 48 h, and 72 h in the FTS group were significantly lower than those in the traditional group (P < 0.01).②Compared with the traditional group, the intestinal function recovery time, intake food time, ambulation time, drainage tube duration, and postoperative hospital stay were obviously shorter, the postoperative sleep time at 72 h was obviously longer in the FTS group.③The incidence of nausea and vomiting in the FTS group was significantly lower than that in the traditional group (P < 0.01), the incidences of the other complications such as acid reflux, urinary retention, and breathing difficulty had no significant differences between these two groups (P > 0.05). The satisfaction rate of postoperative analgesic effect in the FTS group was significantly higher than that in the traditional group (P < 0.01).
ConclusionsPerioperative multimodal analgesia for laparoscopic cholecystectomy based on concept of FTS is safe and effective. It could achieve painless effect of laparoscopic cholecystectomy.
