ObjectiveTo compare clinical efficacy of totally laparoscopic gastrectomy (TLG) and conventional laparoscopy-assisted gastrectomy (LAG) and to explore safety and feasibility of total laparoscopic anastomosis in laparoscopic gastrectomy. MethodThe clinical data of 64 patients who received TLG and another 70 patients who received conventional LAG in our department from January 2013 to March 2014 were retrospectively analyzed. ResultsAll procedures were completed successfully. There were no significant differences in the time of anastomosis〔(73.8±10.3) min versus (72.7±8.9) min, t=0.693, P=0.489〕 and the number of dissected lymph nodes (32.4±9.7 versus 33.6±9.6, t=-0.700, P=0.485) between the patients underwent TLG and the patients underwent LAG. However there were obvious differences in the blood loss〔(275.0±66.3) mL versus (364.3±75.7) mL, t=-7.419, P=0.000〕, the incision length〔(3.0±0.8) cm versus (7.3±1.7) cm, t=-19.354, P=0.000〕, the time to fluid diet〔(4.9±0.8) d versus (6.0±0.7) d, t=-8.750, P=0.000〕 and the time to flatus 〔(2.8±0.8) d versus (3.9±0.8) d, t=-8.388, P=0.000〕, the off-bed time〔(1.3±0.5) d versus (3.4±1.2) d, t=-14.118, P=0.000〕, and the hospital stay〔(9.8±1.2) d versus (13.0±1.5) d, t=-17.471, P=0.000〕 between the patients underwent TLG and the patients underwent LAG. Meanwhile it was found that the postoperative pain score〔On day 1 postoperatively: (3.4±0.8) points versus (6.2±1.3) points, t=-15.509, P=0.000; on day 3 postoperatively: (1.7±0.6) points versus (4.0±0.8) points, t=-18.799, P=0.000〕 and the dosage of pain killers (1.7±0.7 versus 4.0±2.1, t=-8.912, P=0.000) in the patients underwent TLG were significantly lower than those in the patients underwent LAG. One patient developed anastomotic leakage and 3 patients developed anastomotic stenosis in the patients underwent LAG, the complication rate related to the anastomosis was 5.7% (4/70). While there were no complications related to the anastomosis in including anastomotic leakage, stenosis, and bleeding in the patients underwent TLG. ConclusionsTotal laparoscopic anastomosis is safe and feasible in laparoscopic gastrectomy for gastric cancer. Compared with small incision-assisted anastomosis, totally laparoscopic anastomosis is associated with minimal trauma, less blood, quicker postoperative recovery, shorter time, slighter pain and satisfactory short-term efficacy.
Objective To summarize the research progress of CO2 pneumoperitoneum impacts on invasiveness of cancer cells. Methods Currently published experimental and clinical researches related to the effect of CO2 pneumoperitoneum on invasiveness of cancer cells were reviewed. Results CO2 pneumoperitoneum may affect the invasiveness of cancer cell through several ways， such as changing the structure and function of mesothelial cell， changing microenvironment of peritoneum， influencing the expression of oncogen， affecting the secretion of cell factor， and changing the adhesion of cancer cell. Conclusions The consequences of these alterations to cancer cell and the microenvironment are not well understood， but they may facilitate tumor invasion and implantation. Further investigations in this area are very urgent.
ObjectivesTo systematically review the perinatal outcomes after laparoscopic myomectomy versus transabdominal myomectomy.MethodsPubMed, Web of Science, Elsevier, The Cochrane Library, CNKI, VIP and WanFang Data databases were searched from inception to July 2017, to collect randomized controlled trials or cohort studies comparing the perinatal outcomes after laparoscopic myomectomy and transabdominal myomectomy. Two reviewers independently screened literature, extracted data and assessed the risk of bias of include studies. Meta-analysis was then performed by RevMan 5.3 software.ResultsEight randomized controlled trials, twenty-one cohort studies involving 4357 patients were included. The results of meta-analysis showed that: the premature birth rate (OR=0.60, 95%CI 0.38 to 0.95, P=0.03) in the laparoscopic myomectomy was lower than that in the laparotomy group. However, the rate of uterine rupture during pregnancy (OR=3.19, 95%CI 1.29 to 7.89, P=0.01) in the laparoscopic myomectomy was higher than that in the laparotomy group. There were no significant differences between two groups in the myoma residual (OR=1.00, 95%CI 0.37 to 2.65, P=0.99), recurrence (OR=0.92, 95%CI 0.68 to 1.25, P=0.60), abortion (OR=0.90, 95%CI 0.63 to 1.28, P=0.56), ectopic pregnancy (OR=1.11, 95%CI 0.54 to 2.26, P=0.78), pregnancy rate (OR=1.06, 95%CI 0.89 to 1.27, P=0.52), cesarean (OR=0.82, 95%CI 0.57 to 1.19, P=0.31), and pregnancy complications (OR=0.84, 95%CI 0.45 to 1.59, P=0.60).ConclusionsCurrent evidence shows that there are no significant differences between two groups in the myoma residual, myoma recurrence, abortion, ectopic pregnancy, pregnancy rate, cesarean and pregnancy complications. While the rate of uterine rupture during pregnancy in the laparoscopic myomectomy is higher than that in the laparotomy group, the premature birth rate after operation in the laparoscopic myomectomy is lower and shorter than that in the laparotomy group. Due to the limited quantity and quality of the included studies, more high quality studies are required to verify the above conclusion.
ObjectiveTo explore the clinical effect and safety of laparoscopic cytoreductive surgery combined with gestrinone in the treatment of adenomyosis. MethodsWe retrospectively analyzed the clinical data of 82 patients with adenomyosis who accepted treatment in our hospital from January 2008 to April 2011. According to different treatment method, the patients were divided into three groups. Twenty-seven patients in the treatment group underwent laparoscopic cytoreductive surgery combined with postoperative treatment with gestrinone. For the 25 patients in the surgery group, only laparoscopic cytoreductive surgery was performed, and 30 other patients who only received oral gestrinone were designated as the medicine group. Dysmenorrhea, menstrual volume, uterine size, serum carcinoembryonic antigen 125 (CA125), anemia, and drug side effects were respectively recorded before and after surgery. ResultsThe dysmenorrhea degree reduced significantly in all the three groups. There was no significant difference in the degree of dysmenorrhea, menstrual volume, and uterine volume between the treatment group and the surgery group (P>0.05); the dysmenorrhea degree was significantly different between the treatment group and the medicine group (P<0.05); the differences in hemoglobin levels and the serum CA125 level between the treatment group and the surgery group 12 months later were significant (P=0.019, P=0.049). ConclusionThe laparoscopic cytoreductive surgery combined with gestrinone in treating adenomyosis can improve recent curative effect and provide more effective symptom control compared with surgery alone.
ObjectiveTo evaluate the safety and feasibility of laparoscopic resection of primary retroperitoneal tumors. MethodClinical data of 52 patients diagnosed as primary retroperitoneal tumor who underwent laparoscopic resection in Peking University Third Hospital from January 2006 to December 2015 were retrospectively collected and analyzed. ResultsFifty two patients were included in the review. In 21 patients (40.3%), tumors were adjacent to major vessels (such as inferior vena cava, superior mesenteric vein, and the splenic vessel), tumors of 31 patients (59.7%) were away from major vessles. Two operations (3.8%) were converted to hand-assistant and 2 operations (3.8%) were converted to laparotomy due to tight adherence to major vessels. The mean value of operative time was 171.4-minute (60-520 minutes) and the mean value of length of incision was 2.8 cm (1-15 cm), the mean value of estimated blood loss was 86.4 mL (10-1 150 mL), 2 patients needed blood transfusion. The mean value of time of returning to diets was 1.5-day (1-5 days) and the mean value of length of postoperative hospital stay was 4.9-day (1-16 days). There was no major postoperative complications or death. Follow up was available for 47 patients at a median time of 62.0-month (4-120 months). Three patients with retroperitoneal liposarcomas experienced recurrence at 31, 34, and 48 months after operation, 1 patient with mucinous peripheral neurilemmoma experience recurrence at 69 months after operation, all of which underwent further resection, with others experiencing no recurrence or metastasis. Three patients died in reason of other diseases. ConclusionsLaparoscopic surgery can be performed safely in the treatment of primary retroperitoneal tumors, even when a tumor adjacent to major vascular structures.
Objective To systematically evaluate the effectiveness and cost of laparoscopic myomectomy (LM) vs. traditional abdominal myomectomy (TAM) in treating Chinese patients with hysteromyoma. Methods Such databases as The Cochrane Library (Issue 4, 2012), PubMed, EMbase, CNKI, CBM and WanFang Data were searched from their inception to September, 2012 to collect the randomized controlled trials (RCTs) about LM vs. TAM in treating Chinese patients with hysteromyoma, and the references of the included studies were also retrieved. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data and assessed the methodological quality. Then meta-analysis was conducted using RevMan 5.2 software. Results A total of 8 RCTs involving 1 000 Chinese patients were included. The results of meta-analysis showed that, LM was superior to TAM in postoperative exhaust time (WMD= ?15.21, 95%CI ?20.19 to ?10.24, Plt;0.000 01) and postoperative hospital stay (WMD= ?3.07, 95%CI ?4.25 to ?1.90, Plt;0.000 01), with significant differences. But it was inferior to TAM in operation time (WMD=28.33, 95%CI 18.07 to 38.59, Plt;0.000 01) and hospital costs (WMD=2 028.87, 95%CI 1 190.75 to 2 866.98, Plt;0.000 01), with a significant difference. There was no significant difference in intraoperative bleeding amount between the two groups (WMD= ?2.78, 95%CI ?41.56 to 36.00, P=0.89). Conclusion This study shows LM is superior to TAM in fastening postoperative recovery and shortening hospital stay, but it is longer in operation time and higher in cost. The intraoperative bleeding amount is similar in the two groups. Due to low methodological quality and small sample size of the included studies, this conclusion has to be further proved by more high-quality RCTs.
Objective To explore the clinical value of laparoscopy in the treatment of pancreatic diseases. Methods Twelve patients with pancreatic diseases received laparoscopic surgery. Among which 9 patients with cystic diseases, 4 cases underwent laparoscopic spleen-preserving distal pancreatectomy, 2 cases received distal pancreatectomy and splenectomy, and 3 cases underwent pancreatic cystectomy. Laparoscopic insulinoma enucleation was performed for 2 patients who suffered from insulinoma. Besides, a patient suffered from pancreatic carcinoma recurrence received left thoracoscopic splanchnicectomy. Results All the operations were accomplished successfully, including 8 total laparoscopic surgery and 4 laparoscopic assisted surgery. The average operative time was 225 min （range 100-420 min）, and the average volume of blood loss was 80 ml （range 2-150 ml）. Pancreatic fistula was observed in 1 patient which was cured by conservative therapy. The postoperative average hospital stay was 7.2 d （range 5-13 d）. The patient with recurrent pancreatic carcinoma survived for 6 months after operation and the pain-killing effect was satisfactory. With a follow-up of 10-36 months for other patients, the surgical effects were ideal and no recurrence occurred.Conclusion With the advantages of less trauma， less pain， fast recovery， and low morbidity rate, laparoscopic surgery is an effective and safe method for the treatment of pancreatic diseases, and thus may be widely used in the clinical settings in the future.
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.
Objective To investigate the effects of hand assistant laporoscopic splenectomy plus pericardial devascularization on systemic stress responses. Methods Forty patients with cirrhotic portal hypertension were selected， 20 cases of which were underwent hand assistant laparoscopic splenectomy plus pericardial devascularization (LAP group)， and the other 20 were underwent open splenectomy plus pericardial devascularization (OP group). The levels of blood glucose （BG）, insulin (Ins), triiodothyronine （T3）, tetraiodothyronine （T4）, corticosteroid （CS） and other related clinical data were measured before operation and on day 1-3 after operation, which were compared between two groups. Results There was no statistical significance between two groups on those levels before operation. On day 1 after operation， BG and CS level in both two groups were higher than those before operation (P＜0.05), but they were recovered on day 2 after operation in LAP group (Pgt;0.05), and on day 3 after operation in OP group (Pgt;0.05). BG and CS level in OP group were markedly higher than those in LAP group on day 2 after operation (P＜0.05). On day 1 after operation， Ins, T3 and T4 level of two groups were lower than those before operation (P＜0.05), but they were recovered on day 2 after operation in LAP group (Pgt;0.05) and on day 3 after operation in OP group (Pgt;0.05). Ins, T3 and T4 level in OP group were lower than those in LAP group on day 2 after operation (P＜0.05). There was no significant difference in operation time between two groups (Pgt;0.05). But laparoscopic surgery had more advantages than conventional open surgery such as reducing bleeding quantity in operation, shortening recovery time of bowel and urinary bladder function and the length of stay. Conclusion Compared with laparotomy, the laparoscope not only imposes less impact on physical stress system, but also makes recovery after operation more quickly.
Objective To compare the surgical outcome and investigate the clinic value between laparoscopic operation and laparotomy in the treatment of ectopic pregnancy. Methods We searched PubMed, EMbase, SCI, The Cochrane Library, Chinese Biomedical Literature Database, China Journal Full Text Database, Chinese Medical Association Journals, and references of the included studies up to April 2009. Studies involving treatment outcome of ectopic pregnancy using laparoscopy compared with laparotomy were included. Data were extracted and methodological quality were evaluated by two reviewers independently with designed extraction form. The Cochrane Collaboration’s RevMan 5.0.1 software was used for data analyses. Results A total of 11 studies involving 1795 patients were included. The results of meta-analyses showed that laparoscopy comparing with laparotomy; the operation time and complications had no difference; intraoperative blood loss was less than laparotomy; intestinal gas exhaust and evacuation active time was earlier than laparotomy. Conclusion Laparoscopy treating for ectopic pregnancy is better than laparotomy. It is a minimally invasive surgical technique, and is worthy to be popularized.
