Objective To compare the efficacy and incidence of complications between laparoscopic surgery and laparotomy on women with polycystic ovarian syndrome (PCOS). Methods We did a systematic literature search for studies from Ovid Database, MEDLINE, EMbase, Cochrane Library (Issue 2, 2008), Chinese Biological Medicine Database, CNKI, Chinese VIP Database, and WANFANG Database on internet. The search time was from establishment of each database to December, 2008. Randomized controlled trials and non-randomized controlled trials were collected. The search was no limitation in language. We manually searched current and conference abstracts, and searched relevant reviews and their reference. RevMan 5.0 software was used for meta-analysis. Results Five non-randomized trials involving 417 patients were included. The results of meta-analyse showed that the short-term pregnancy rate in patients underwent laparoscopic surgery was significantly higher than that in patients underwent laparotomy (RR=1.42, 95% CI 1.13 to 1.80, P=0.003). The long-term pregnancy rate in patients underwent laparoscopic surgery and laparotomy was comparable (RR=0.85, 95%CI 0.68 to 1.07, P=0.17). The regular menstruation in patients underwent laparoscopic surgery and laparotomy was comparable (RR=0.91, 95%CI 0.79 to 1.05, P=0.18). The uterine adhesions in patients underwent laparoscopic surgery was significantly lower than that in patients underwent laparotomy (RR=0.02, 95%CI 0.00 to 0.18, P=0.000 2). The intra-abdominal adhesions of patients underwent laparoscopic surgery was significantly lower than that in patients underwent laparotomy (RR=0.02, 95%CI 0.00 to 0.13, Plt;0.000 1).Conclusions The limited evidence at present shows that the incidence and degree of pelvic adhesions occurred in patients with PCOS after laparoscopic surgery is much lower than those after laparotomy. It is not quite sure at this point about whether the pregnancy rate and regular menstruation of laparoscopic surgery are better than those of lararotomy or not. More evidence from high qualified multi-center studies is needed.
ObjectiveTo systematically evaluation the efficacy and safety of laparoscopic cholecystectomy(LC) and open cholecystectomy(OC) for chronic atrophic cholecystitis. MethodsStandard electronic database such as PubMed, Web of science, Cochrane library, CNKI, VIP, CBM, and Wanfang database were searched to retrieve relevant randomized controlled trials(RCTs) that comparing LC with OC, which were analyzed systematically using RevMan5.2. ResultsSeven RCTs including 758 patients were brought into this Meta analysis. There were significant differences between two groups regarding operative time(MD=-27.70, 95% CI:-44.25--11.16, P=0.001), amount of blood loss during operation(MD=-113.25, 95% CI:-141.68--84.81, P < 0.000 01), the recovery time of gastrointestinal function(MD=-28.49, 95% CI:-29.80--27.18, P < 0.000 01), and length of hospital stay(MD=-3.83, 95% CI:-6.01--1.65, P=0.000 6), There were statistically significant difference in utilization rate of anodynes after operation(MD=0.12, 95% CI:0.06-0.23, P < 0.000 1) and terrible postoperative complications(MD=0.24, 95% CI:0.12-0.47, P < 0.000 01) between LC and OC. ConclusionsIn both efficacy and safety, LC for chronic atrophic cholecystitis are significantly superior than the traditional OC. But now the clinical randomized controlled trials about LC is less and the quality is poor, so that its long-term safety evaluation still needs large sample quality RCTs to be further verified.
ObjectiveTo study the application value of mixed formulations consisting of paraffin oil, dimethyl silicone oil, and senna preparations in treatment for incomplete adhesive intestinal obstruction after laparotomy. MethodsOne hundred and twentyeight patients diagnosed incomplete adhesive intestinal obstruction admitted to this hospital from March 2005 to May 2008 were randomly divided into trial group and control group. For the control group, the tradition therapy including fasting, gastrointestinal decompression, fluid replacement therapy, and enema with soap and water were used for treatment. For the trial group, the mixed formulations consisting of paraffin oil, dimethyl silicone oil, and senna preparations were injected into stomach by the nasogastric tube on the basis of traditional treatment used for the control group. Some indicators including the successful rate of nonoperative treatment, the time that obstructive symptoms resolved and returned to normal exhaust and defecation and normal diet, and recurrence rate were compared between two groups. ResultsThe successful rate of nonoperative treatmentin in the trial group were significantly higher than that in the control group 〔92.1% (70/76) versus 69.2% (36/52), Plt;0.01〕. The average time that recovered to normal exhaust and defecation in the trial group and the control group was 32.5 d and 47.8 d, respectively. The average time that recovered to normal diet in the trial group and the control group was 3.2 d and 5.3 d, respectively. The time that recovered to normal exhaust and defecation, and diet in the trial group were significantly shorter than those in the control group (Plt;0.01). The recurrence rate had no significant difference between two groups (Pgt;0.05). ConclusionThe mixed formulations consisting of paraffin oil, dimethyl silicone oil, and senna preparations improve recovery of intestinal function and reduce surgical intervention rate.
ObjectiveTo compare the cost-effectiveness between endoscopic retrograde cholangio-pancreatography (ERCP) treatment and laparotomy treatment for simple common bile duct stone or common bile duct stone combined with gallbladder benign lesions. MethodsA total of 596 patients with common bile stone received ERCP (ERCP group) and 173 received open choledocholithotomy (surgical group) in our hospital between January 2009 and December 2012. Their clinical data were retrospectively analyzed. The curing rate, postoperative complications, hospital stay, preoperational preparation and total cost were compared between the two groups of patients. Meanwhile, for common bile stone combined with gallbladder benign lesion, 29 patients received ERCP combined with laparoscopic cholecystectomy (LC) (ERCP+LC group), 38 received pure laparoscopy treatment (laparoscopy group) and 129 received open choledocholithotomy combined with cholecystectomy (surgery group). ResultsFor simple common bile stone patients, no significant difference was found in cure rate and post-operative complication between endoscopic and surgical treatment groups (P>0.05). However, total hospitalization expenses[(13.1±6.3) thousand yuan, (20.6±7.5) thousand yuan)], hospital stay[(8.91±4.95), (12.14±5.15) days] and preoperative preparation time[(3.77±3.09), (5.13±3.99) days] were significantly different between the two groups (P<0.05). For patients with common bile stone combined with gallbladder benign lesion, no significant discrepancy was detected among the three groups in curing rate and post-operative complications (P>0.05). Significant differences were detected between ERCP+LC group and surgical group in terms of total hospitalization expense[(18.9±4.6) thousand yuan, (23.2±8.9) thousand yuan] hospital stay[(9.00±3.74), (12.47±4.50) days] and preoperative preparation time[(3.24±1.83), (5.15±2.98) days]. No significant difference was found in total hospitalization expense and hospital stay, while significant difference was detected in preoperative preparation time between ERCP+LC group and simple LC group. ConclusionFor patients with simple common bile stone, ERCP is equivalent to surgery in the curing rate, and has more advantages such as less cost, shorter length of hospital stay, and lower preoperative preparation time. For the treatment of common bile duct stone with gallbladder benign disease, ERCP combined with LC also has more advantages than traditional surgery.
ObjectiveTo compare the effect and safety between laparoscopic versus laparotomy D2 radical gastrectomy for advanced gastric cancer. MethodsTwo hundred and seventeen patients with advanced gastric cancer who were treated in our hospital from March 2011 to March 2014 were selected as research objects. According to surgical method, they were divided into laparoscopy group (103 patients received laparoscopic D2 radical gastrectomy) and laparotomy group (114 patients received laparotomy D2 radical gastrectomy). Comparison of the surgical effect-related indicators between 2 groups was performed. ResultsIn the aspect of intra-operative indicators:the operation time, proximal margin length, distal margin length, and the number of removal lymph node between the 2 groups did not significantly differed with each other (P>0.05); while the bleeding volume and the length of incision in laparoscopy group were significantly less (shorter) than those of laparotomy group (P<0.05). In the aspect of post-operative indicators:the time to first flatus, time to resumed oral intake, time to ambulation, post-operative hospital stay, time of analgesics given, and the total incidence of postoperative complication in laparoscopy group were significantly shorter (less or lower) than those of laparotomy group (P<0.05), the operating cost in laparoscopy group was significantly higher than that of the laparotomy group (P<0.05), but there was no significant difference in total treatment cost, mortality of gastric cancer, and recurrence or metastasis rate between the 2 groups (P>0.05). ConclusionsBoth laparoscopic and laparotomy D2 radical gastrectomy in treatment of advanced gastric cancer can obtain good clinical effect. But compared with laparotomy D2 radical gastrectomy, laparoscopic D2 radical gastrectomy can reduce operative wound, reduce incidence of complications, improve postoperative recovery, and has higher safety.
ObjectiveTo systematically review the effect of laparoscopy versus laparotomy for borderline ovarian tumors (BOTs) on postoperative recurrence. MethodsWe searched PubMed, The Cochrane Library (Issue 11, 2015), EMbase, Web of Science, CNKI, WanFang Data and CBM databases from inception to Nov. 2015, to collect relevant clinical studies comparing laparoscopy and laparotomy for BOTs. Two reviewer independently screened literature, extracted data and assessed the risk of bias of include studies by using NOS scale. Then, meta-analysis was performed by using RevMan 5.3 software. ResultsNineteen cohort studies were included. The scores of NOS scale showed that 10 studies were < 7 points, while the other 9 studies were≥7 points. The results of meta-analysis showed that: the recurrence rate of tumor (OR=1.75, 95%CI 1.05 to 2.91, P=0.03) in the laparoscopy group was higher than that in the laparotomy group, but no significant differences were found in further subgroup analysis according to type of operations (conservative surgery: OR=1.22, 95%CI 0.71 to 2.08, P=0.47; non-conservative surgery: OR=4.38, 95% CI 0.85 to 22.68, P=0.08). The diameter of tumor in the laparoscopy group was significant smaller than that in the laparotomy group (MD=-6.88, 95% CI-8.15 to-5.61, P < 0.000 01), and the rate of rupture of tumor in the laparoscopy group was significant higher than that in the laparotomy group (OR=3.99, 95% CI 2.54 to 6.26, P < 0.000 01). ConclusionCurrent evidence shows, compared with laparotomy, laparoscopy has similar effect on postoperative recurrence and smaller diameter of tumor, but laparoscopy could increase the rate of rupture of tumor. Due to the limited quality and sample size of included studies, more high quality and large sample size studies are need to prove the above conclusion.
ObjectiveTo systematically review the effectiveness and safety of laparoscopic operation versus laparotomy for stage I-IIa cervical cancer. MethodDatabases including PubMed, EMbase, Web of Knowledge, CBM, WanFang Data and CNKI were searched to collect controlled trials and cohort studies about laparoscopic operation versus laparotomy for stage I-IIa cervical cancer from inception to July 2014. Two reviewers independently screened literature, extracted data, and evaluated the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsA total of 3 RCTs, 4 non-randomized controlled trials and 11 cohort studies involving 2 020 patients were included. The results of meta-analysis showed that, compared with laparotomy, laparoscopy operation could reduce intraoperative blood loss (MD=-247.99, 95%CI -408.90 to -87.07, P=0.003) , the incidence of perioperative blood transfusion (OR=0.33, 95%CI 0.21 to 0.52, P<0.000 01) , haemoglobin level before and after surgery (MD=-0.98, 95%CI -0.13 to -0.93, P<0.000 01) , postoperative complication (OR=0.61, 95%CI 0.40 to 0.93, P=0.02) , and shorten postoperative exhaust time (MD=-17.41, 95%CI -32.79 to -2.03, P=0.03) and postoperative hospitalization days (MD=-2.51, 95%CI -3.25 to -1.78, P<0.000 01) . There were no significant differences between two groups in the number of pelvic lymph nodes removed, operative complications, as well as the recurrence rate, mortality and non-recurrence survivals after 2 to 5 years of follow-up. But the operation time of the laparoscopy operation group was longer than that of the laparotomy group. ConclusionsCurrent evidence shows that compared with laparotomy, laparoscopic operation for early stage cervical cancer has less trauma, less blood loss, shorter hospitalization days and less postoperative complications. Due to the limited quantity of the included studies, more studies are needed to verify the above conclusion.
ObjectiveTo systemically evaluate safety and effectiveness of laparoscopy-assisted distal gastrectomy (LADG) and conventional open distal gastrostomy(CODG) with D2 lymph node dissection for Chinese patients with distal gastric cancer. MethodsLiterature were searched in PubMed database, the Cochrane Library, China science citation database (CSCD), Wanfang database, China science and technology journal database (CSTJ), China biomedical literature database (CBM), and China academic journal network publishing database (CAJD) to identify clinical random controlled trials, comparing safety and effectiveness of LADG and CODG with D2 lymph node dissection for Chinese patients with distal gastric cancer. The retrieval time was from the inception to Jun. 2013. Meta-analysis was performed by Review Manager 5.2 software. ResultsA total of 7 clinical random controlled trials including 548 patients were analyzed. Compared with CODG group, LADG group had less blood loss (MD=-94.02, 95% CI:-140.96--47.07), shorter postoperative hospital stay(MD=-3.66, 95% CI:-5.76--1.57), earlier postoperative ambulation time(MD=-1.95, 95% CI:-2.74--1.17), earlier postoperative exhaust time (MD=-1.67, 95% CI:-2.05--1.30), lower incidence of complications(OR=0.26, 95% CI:0.14-0.51), P<0.050. But the operation time was longer in LADG group (MD=35.01, 95% CI:10.41-59.61, P=0.005). There was no significant difference between LADG group and CODG group on number of lymph node which were dissected during the operation (MD=-0.24, 95% CI:-0.99-0.51, P=0.530). ConclusionThe short-term outcome and safety of LADG for Chinese patients with distal gastric cancer is superior to CODG, but LADG prolongs the operation time and its long-term outcome should be proved by further outcomes of clinical controlled trials.
ObjectiveTo explore the diagnostic and therapeutic significance of laparoscopic surgery for abdominal trauma patients. MethodsClinical data of 65 patients with abdominal trauma who treated in Affiliated Laigang Hospital of Taishan Medical College from January 2010 to December 2014 were collected retrospectively, all patients were diagnosed by laparoscopic exploration, and therapies were depended on the results of laparoscopic exploration. ResultsOf the 65 patients, 60 patients were definitely diagnosed through laparoscopic exploration, but 5 patients transferred to laparotomy because of clear diagnosis was not achieved under laparoscopy. Of the 60 patients who were diagnosed clearly by laparoscopy, 23 patients didn't received any intervention because of no obvious injury observed, 27 patients received laparoscopic surgery (3 patients were assisted with hands), and 10 patients transferred to open operation because of peritoneal contamination. Incision infection occurred in 1 patient after operation, 1 patient suffered from subphrenic abscess, and other 63 patients didn't suffered from any complication. All of the patients were discharged successfully. All of the 65 patients were followed up for 2-48 months with the median time of 10 months. Severe complications did not occurred and no patient needed re-operation within the period of follow-up period. ConclusionsLaparoscopy is feasible, safe, and effective for the evaluation and treatment of abdominal trauma patients with stable hemodynamics, and it also has a higher diagnostic rate. Laparoscopy can also reduce the negative exploratory laparotomy for the abdominal trauma patients.
Objective To analyze the treatment and effect of bacterial liver abscess over the past two decades in one single center. Methods The total 198 patients with bacterial liver abscess during the last twenty years were studied retrospectively. They were divided into three groups according time: 1989-1995 group, 1996-2002 group and 2003-2008 group. Gender and age of patient, location, number and size of abscesses, treatment, hospital days, morbidity of complications and mortality among the groups were compared. Results There were 54, 69, 75 cases in 1989-1995, 1996-2002 and 2003-2008 group respectively. No significant differences were found in gender and age of patient, location, number and size of abscess among three groups （Pgt;0.05）. In 1989-1995 group, 35 cases (64.8%) were treated with laparotomy, 8 cases (14.8%) with laparoscope, and 11 cases (20.4%) with percutaneous treatment (needle aspiration or catheter drainage). In 1996-2002 group, 15 cases (21.8%) were treated with laparotomy, 21 cases (30.4%) with laparoscope, 31 cases (44.9%) with percutaneous treatment (needle aspiration or catheter drainage), and 2 cases (2.9%) were treated with antibiotherapy. In 2003-2008 group, 5 cases (6.7%) were treated with laparotomy, 13 cases (17.3%) with laparoscope, 54 cases (72.0%) with percutaneous treatment (needle aspiration or catheter drainage), and 3 cases (4.0%) were treated with antibiotherapy. The constituent ratio of treatment was significantly different among three groups (P＜0.05). The hospital days was (18.5±12.2) d, (16.4±12.8) d and (20.1±14.6) d, the morbidity of complications was 9.3% (5/54), 4.3%(3/69) and 4.0%(3/75), the mortality was 3.7%(2/54), 1.4%(1/69) and 1.3% (1/75) respectively, but there were no significant differences of three indexes among three groups. Conclusion With the development of surgical techniques, effective antibiotic therapy and percutaneous treatment (needle aspiration or catheter drainage) have been the main therapeutic methods, and laparoscopy and laparotomy are necessary supplement.
