Objectives To analyze the efficacy and safety of different operation methods for patients with cesarean scar diverticulum. Methods The clinical data of patients with cesarean section scar diverticulum treated in West China Second University Hospital from July 2012 to December 2016 was collected and followed up. The data of the previous perioperative period data, recovery, the improvement of the symptoms and postoperative condition of incision healing were analyzed by SPSS 22.0 software. Results A total of 125 patients were included, in which 74 cases received hysteroscopy surgery for diverticulum electro section and electric coagulation (ESEC group), and 51 cases received other surgery focused on diverticulum dissection and sewing operations (DS group). Statistical analysis showed that, compared with DS group, bleeding, operation time, time of anal exsufflation and hospitalization duration after the operation of hysteroscopy in ESEC group were significantly reduced (P<0.001). In addition, the results showed that hysteroscopy group had optimal results in hemorrhage volume, operation time, anal exhaust time and hospitalization time indicators. However, the results of laparotomy group was not significant. Conclusions For the treatment of CSD, surgical treatment of this pathology by operative hysteroscopy may represent the best choice in symptomatic women because of its minimal invasiveness and beneficial therapeutic results. Hysteroscopy isthmoplasty appears to be the most popular treatment.
ObjectiveTo systematically evaluate the stress response of laparoscopic surgery (LS) and conventional open surgery (OS) in patients with colorectal cancer. MethodsThe literatures about the immune stress response of LS and OS for colorectal cancer were collected from PubMed, Springer, OVID, Cochrane library, CNKI, VIP Database, and Wanfang Database from May 2001 to September 2014. RevMan 5.3 software was used for data analysis. ResultsFifteen randomized controlled trials including 881 patients were brought into this Meta analysis, of 881 patients, 424 patients were treated with LS and 457 patients were treated with OS. The results of Meta-analysis showed that:①At 24, 72, and 120 hours after surgery, the levels of interleukin (IL-6) in LS group were all lower than those of OS group at same time point[24 h (WMD=-27.78, 95% CI:-43.24--12.32, P < 0.01), 72 h (WMD=-13.23, 95% CI:-19.89--6.57, P < 0.01), 120 h (WMD=-16.51, 95% CI:-30.13--2.89, P=0.02)]. ②At 24, 72, and 120 hours after surgery, the levels of C reactive protein (CRP) in LS group were all lower than those of OS group at same time point[24 h (WMD=-31.11, 95% CI:-47.49--14.73, P < 0.01), 72 h (WMD=-29.81, 95% CI:-49.99--9.64, P < 0.01), 120 h (WMD=-32.03, 95% CI:-45.34--18.71, P < 0.01)]. ③There was no significant difference between the 2 groups in WBC level at 24 hours after surgery (WMD=-0.63, 95% CI:-1.80-0.54, P=0.29), but the WBC levels of LS group at 72 hours and 120 hours after surgery were lower than those of OS group[72 h (WMD=-0.21, 95% CI:-0.41--0.01, P=0.04), 120 h (WMD=-0.86, 95% CI:-1.66--0.06, P=0.03). ④There was no significant difference between the 2 groups in cortisol level at 24 hours and 72 hours after surgery[24 h (WMD=-60.19, 95% CI:-194.77-74.39, P=0.38), 72 h (WMD=-13.83, 95% CI:-43.94-16.28, P=0.37). ⑤There was no significant difference between the 2 groups in blood glucose level at 24 hours and 72 hours after surgery[24 h (WMD=-0.95, 95% CI:-2.74-0.84, P=0.30), 72 h (WMD=-0.69, 95% CI:-2.05-0.66, P=0.32)]. ⑥There was no significant difference between the 2 groups in insulin level (WMD=-0.52, 95% CI:-1.87-0.82, P=0.45) at 24 hours after surgery. ⑦There was no significant difference between the 2 groups in tumor necrosis factor (TNF) level at 24 hours after surgery (WMD=-4.18, 95% CI:-9.39-1.04, P=0.12). ConclusionCompared with open radical surgery, laparoscopic radical surgery for colorectal cancer causes less stress and less effect on the immune function, it also can reduce postoperative complications and can be propitious to faster body recovery.
ObjectiveTo investigate the clinical value of veress needle with thread for laparoscopic high ligation of hernia sac in children. MethodsThe clinical data of 56 cases of pediatric inguinal hernia using laparoscopic high ligation of hernia sac with veress needle from May 2013 to May 2014 were analyzed retrospectively. ResultsAll patients were successfully carried out operation by laparoscopic high ligation of hernia sac.Forty-one cases underwent unilateral surgery, and operative time was 6-18 min (mean 9.6 min); 15 cases underwent bilateral surgery, and operative time was 10-32 min (mean 14.3 min).Nine cases of contralateral recessive hernia were found and ligated during operation.There was no complications, such as scrotal edema, scrotal gas or incision infection after operation, and all patients were discharged in l-2 days after operation.No recurrence or testicular dysplasia was found during 3 to 15 months (mean 10.8 months) follow-up. ConclusionsThere are many advantages in laparoscopic high ligation of hernia sac with veress needle, such as less damage, hidden incision, faster recovery, shorter hospital stay, simple operation, and better efficacy.We can find contralateral recessive hernia during operation and avoid second surgery with high clinical value, therefore it is worthy of clinical application.
ObjectiveTo investigate the changes of peritoneal macrophages function of mice with gastric cancer in the CO2 pneumoperitoneum environment, as well as its effect on the peritoneal metastasis of gastric cancer. MethodsAn orthotopic implantation model of mouse forestomach cancer was established using the 615 mouse. The mice bearing tumors were randomly divided into five groups (n=30): anesthesia alone, laparotomy, and 2, 4, and 6 mm Hg CO2 insufflation groups. Peritoneal macrophages were collected from six mice in each group and cultured. The macrophage phagocytic function on neutral red and the levels of NO and TNF-α produced by macrophages were measured after 12, 24, 48, and 72 h of culture. The remaining mice were observed after two weeks for the rate of peritoneal metastasis of forestomach cancer cells and the total weight of implanted nodules. ResultsNo death and ascites were found and the difference of weight body was not significant in all mice (Pgt;0.05). The uptake of neutral red by peritoneal macrophages and the levels of NO and TNF-α secreted by peritoneal macrophages in the laparotomy group after 12 h of culture were all significantly higher than those in other four groups (Plt;0.05). The corresponding values in the 2, 4， and 6 mm Hg CO2 insufflation groups after 12 h were all significantly lower than those in the anesthesia alone group (Plt;0.05). Among three insufflation groups, the corresponding values in the 2 mm Hg after 12 h were significantly higher than those in the 4 and 6 mm Hg CO2 insufflation group, though the difference in the two latter was not significant (Pgt;0.05). The uptake of neutral red by peritoneal macrophages and the levels of NO and TNF-α secreted by peritoneal macrophages in the 6 mm Hg CO2 insufflation group after 24 h of culture were all significantly lower than those in other four groups (Plt;0.05), while the difference in the four groups was not significant (Pgt;0.05). The uptake of neutral red by peritoneal macrophages and the levels of NO and TNF-α secreted by peritoneal macrophages after 48 h and 72 h were not significantly different in the five groups (Pgt;0.05). The rate of peritoneal metastasis of mice was significantly lower in the 6 mm Hg insufflation CO2 group (75.0%, 15/20) than that in the anesthesia alone group (100%, 24/24), Plt;0.05, but higher than other three groups(Plt;0.05), which was not different in 2 mm Hg (47.8%, 11/23), 4 mm Hg insufflation group (45.45%, 10/22) and laparotomy group (50.0%, 10/20), Pgt;0.05. The total weight of implanted nodules of mouse forestomach cancer was (1.24±0.48) g, (1.02±0.38) g, (0.96±0.33) g, (0.93±0.45) g, and (1.18±0.37) g in the anesthesia alone group, the laparotomy group, and 2, 4, and 6 mm Hg CO2 insufflation group, and the difference was not significant (Pgt;0.05). ConclusionHigh pressure (6 mm Hg) CO2 pneumoperitoneum can constantly inhibit the phagocytosis and cytokine secretion functions of peritoneal macrophages in gastric cancer-bearing mice and promote peritoneal implantation of gastric cancer.
Objective To explore the value of laparoscopic hepatectomy for small hepatocellular carcinoma (HCC) of non-peripheral type. Methods The clinical data of 34 patients with small HCC of non-peripheral type underwent laparoscopic liver resection from March 2008 to April 2011 in our hospital were analyzed retrospectively. Results Thirty-two patients received successful total laparoscopic hepatectomy without blockage of liver blood flow，and 2 were converted to open surgery. The operative time was （162±65） min （100-220 min） and the blood loss was （295±166） ml （100-750 ml）. There were postoperative complications in 4 patients， included cross-section bleeding in 2 cases and ascites in 2 cases. There were no complications such as biliary fistula， infection， carbon dioxide gas embolism， and so on. The mortality of perioperative period was 0. The postoperative hospital stay was （6±2） d （4-9 d）. The follow-up time was （23±7） months （5-42 months）. Thirteen patients developed intrahepatic tumor recurrence during follow-up. The overall and recurrence-free survival rate one year after operation was 90.6% （29/32）and 75.0% （24/32）， respectively. Conclusions Laparoscopic hepatectomy is a safe， feasible， and minimal invasive approach for small HCC of non-peripheral type，and it can be considered as a alternative treatment of HCC.
Objective To prospectively evaluate the health-related quality of life (HRQOL) outcomes in patients undergoing laparoscopic total mesorectal excision (LTME) with anal sphincter preservation (ASP) for low rectal cancers. Methods From June 2001 to March 2004, 125 patients undergoing LTME and 103 patients undergoing OTME were included in this study. The international standard questionnaires (QLQ-C30 and QLQ-CR38) were used to evaluate the conditions of patients at 3 periods after surgery respetively: 3-6 months, 12-18 months, gt;24 months. Results In contrast to OTME patients, the LTME ones showed significantly better physical function during 3-6 months after surgery, less micturition problems within 12-18 months, less male sexual problems and better sexual function during 12-18 months after surgery, with better sexual enjoyment after postoperative 24 months. Both groups showed significant improvement in most subscales from the first to the second assessment, and improvement in sexual enjoyment from the second to the third assessment. The sexual function, micturition problems and male sexual problems in LTME group significantly improved from the first to the second assessment, whereas the sexual function in OTME group improved from the second to the third assessment.Conclusion Patients undergoing LTME for low rectal cancers have bette postoperative HRQOL than patients undergoing OTME, with better physical function, micturition function, overall sexual and male sexual functions in short term, and better sexual enjoyment in the long term. The HRQOL of both LTME and OTME patients may be expected to improve over time, particularly in the first postoperative year.
Injury of the gallbladder beds on the liver during laparoscopic cholecystectomy of 178 cases for the last year waas analysed. Reoperations in 6 cases with one death due to major postoperative complications. These injuries could be classified into 3 degrees according to extent of liver parenchyma denuded in the bed . Degree Ⅰ, no liver was denuded in the bed with the fibromembranous lining intact (49 cases);Degree Ⅱ, liver denuded area was less than one half of the bed (90 cases);Degree Ⅲ, liver denuded area was greater than half of the bed ( 39 cases). There was close relationship between grade of the bed injury and the postoperative complication. Leaving the lining intact of the bed was most important during the lapatoscopic cholecystectomy in order to prevent complication from the bed. The method was discussed. Drainage of the subhapatic space was suggested when liver bed is denuded.
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.
Objective To formulate an evidence-based treatment plan for a patient with suspected pyogenic liver abscess. Methods Based on the clinical questions raised by a patient with suspected pyogenic liver abscess, we searched The Cochrane Library (Issue 4, 2007), MEDLINE (1996 to January 2008), ACP Journal Club (1991 to January 2008), and Chinese Journal Full-text Database (1994 to January 2008) for systematic reviews, randomized controlled trials (RCTs) and case-control studies. The quality of the included studies was assessed. Results We did not find any systematic reviews or large-scale RCTs involving a comparison between laparoscopic drainage and surgical drainage in the treatment of pyogenic liver abscess. Four clinical retrospective studies closely related to our questions were found and assessed. These studies concluded that laparoscopic drainage for liver abscesses was a safe alternative for patients requiring surgical drainage. Based on the current evidence, as well as our clinical expertise and the patient’s values, laparoscopic drainage was not used for this patient and surgical drainage was applied. The patient was recovered and discharged. Conclusion Current evidence showed that laparoscopic drainage might be effective and safe for liver abscesses but high-quality large-scale randomized controlled trials are still required.
Objective To compare the feasibility， safety， and efficiency of laparoscopic total extraperitoneal （TEP）hernia repair surgery and laparoscopic transabdominal preperitoneal （TAPP） hernia repair surgery. Methods The clinical data of 95 patients with inguinal hernia who underwent laparoscopic TEP hernia repair surgery （TEP group） and TAPP hernia repair surgery （TAPP group） from Mar. 2010 to Oct. 2013 in our hospital were retrospectively analyzed， and clinical parameters including operation time， intraoperative blood loss， postoperative hospital stay， postoperative comp-lication， and operation cost of 2 groups were compared. Results All the procedures were successful， none of them was converted to open surgery. There was no significant difference between TEP group and TAPP group when considering operation time 〔（65±16） min vs.（68±17） min〕， intraoperative blood loss 〔（7.0±1.2） mL vs. （8.0±1.4） mL〕， visual pain analogue scale 〔（2.0±1.1） score vs. （1.8±1.1） score〕， postoperative hospital stay 〔（3.1±1.4） d vs. （3.3±1.2） d〕，and time to release to regular activities 〔（4.2±1.0） d vs. （4.5±1.2） d〕， P＞0.05. But the operation cost of TEP group was significantly lower than that of TAPP group 〔（8 033±536） yuan vs. （9 632±643） yuan， P=0.007〕. There were 6 atients （6.3%， 6/95） suffered complications， 3 cases in TEP group and 3 cases in TAPP group， including 3 cases of seroma or hematoma in scrotum， 1 case of transient neurapraxia， and 3 cases of urinary retention. There was no signi-ficant difference in incidence rate of postoperative complication between the 2 groups （P=1.000）. All patients were followed-up for 1-35 months 〔（20.0±10.2） months〕 without recurrence and chronic pain. Conclusions TEP and TAPP hernia repair surgery are feasible， safe， effective， and minimally invasive technique for inguinal hernioplasty. There are advantages and disadvantages of both TAPP and TEP hernia repair surgery， but there is no statistically significant difference regarding intraoperative and postoperative complications.
