Objective To explore the effect of laparoscopic highly selective vagotomy (Hill) on the treatment for acute perforating duodenal ulcer. Methods In 19 patients with acute perforating duodenal ulcers, laparoscopic repair of the perforation, laparoscopic freeing of the vagus, cutting off of posterior vagal trunk, and highly selective resection of anterior vagal trunk were performed. Results In all 19 cases the operation was successful. No patient was converted into open highly selective vagotomy. Ulcer symptoms of 17 patients disappeared after operation, and gastroscopy in follow up after 6 months showed that the ulcers had healed. The postoperative ulcer symptoms of 2 patients were markedly relieved and were easily controlled by medication. Conclusion The treatment of acute perforating duodenal ulcer by laparoscopic highly selective vagotomy (Hill) has the advantages of minor trauma, rapid postoperative recovery, and good results, it is a good procedure for the treatment of perforating duodenal ulcer.
Objective To evaluate the clinical application of hand assisted laparoscopic radical surgery for gastric cancer. Methods From June 2010 to September 2011，a series of 51 patients were undertook hand assisted laparoscopic D2 gastrectomy （hand assisted group），49 patients were undertook laparoscopic assisted D2 gastrectomy （laparoscopic group），the secure indexes of surgery effect in perioperative period were compared betwee two groups. Results The incision length was （6.82±0.33） cm and （5.74±1.11） cm （t=6.57，P=0.00），numbers of harvested lymph nodes were 16.10±5.11 and 14.16±3.60 （t=2.18，P=0.03），intraoperative bleeding was （249.40±123.40） ml and （251.00±90.40） ml （t=-0.74，P=0.94），operation time was （177.7±23.8） min and （188.1±16.9） min （t=-2.53，P=0.01），postoperative hospital stay was （11.12±5.02） d and （10.88±3.13） d （t=0.29，P=0.78） in the hand assisted group and in the laparoscopic group，respectively. One case of gastric atony happened in the hand assisted group，one case of gastric atony and incision infection happened in the laparoscopic group. No mortality case was found in two groups. Conclusions Hand assisted laparoscopic D2 gastrectomy is less difficult，and shorter operation time，and considerable treatment effection as compared with laparoscopic operation.
ObjectivesTo evaluate the clinical value of laparoscopic exploration in the diagnosis of tuberculous peritonitis by meta-analysis.MethodsThe Cochrane Library, PubMed, Web of Science, WanFang Data, CNKI and VIP databases were electronically searched to collect relevant studies on the diagnostic value of laparoscopic exploration in diagnosing tuberculous peritonitis from January 1st, 1990 to April 1st, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. The Rveman 5.3, Meta-DiSc 1.4 and Stata SE15 software were used for statistical analysis and the receiver operating characteristic curve (SROC) was drawn.ResultsA total of 10 studies involving 1098 patients were included. The results of meta-analysis showed that the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnosis odds ratio and area under the curve of SROC were 0.98 (95%CI 0.96 to 0.98), 0.85 (95%CI 0.78 to 0.91), 4.78 (95%CI 1.98 to 11.54), 0.06 (95%CI 0.03 to 0.12), 111.40 (95%CI 36.55 to 339.58) and 0.971 1, respectively and the Q* was 0.9216.ConclusionsThe existing evidence shows that laparoscopic exploration has higher sensitivity and specificity in the diagnosis of tuberculous peritonitis. Laparoscopic exploration can be used as a diagnosis and treatment tool for patients with tuberculous peritonitis in case the laboratory test cannot determine the origin. Due to the limited quality and quantity of included studies, the above results should be validated by more studies.
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.
Objective To explore the methods， clinical effects， and application value of laparoscopic splenectomy combined with pericardial devascularization. Methods The clinical data of 23 patients with liver cirrhosis and portal hypertension who performed laparoscopic splenectomy combined with pericardial devascularization between july 2009 and july 2012 in our hospital were analyzed retrospectivly. Results In 23 cases， 2 cases were converted laparotomy due to bleeding， 21 cases were successfully performed laparoscopic splenectomy combined with pericardial devascularization. The operative time was 230-380 minutes （average 290 minutes）. The intraoperative blood loss was 300-1 500 mL （average 620 mL）. The postoperative fasting time was 1-3 days （average 2 days）. The postoperative hospital stay was 8-14 days （average 10 days）. Conclusion Laparoscopic splenectomy combined with pericardial devascularization is a feasible， effective， and safe procedure as well as minimally invasive hence is applicable for patients with portal hypertension and hypersplenism．
Objective To study the suitable operation method of elderly patients with acute cholecystitis. Methods The clinical data of 149 elderly patients with acute cholecystitis were retrospectively analyzed. All patients were divided into two groups according to the operation: open cholecystectomy group (OC group, n=76) and laparoscopic cholecystectomy group (LC group, n=73). Some clinical data were compared in this paper such as operation time, blood loss, length of hospital stay, time of resumption of food, time of intestinal function recovery and complications. Results No marked difference was found between OC group and LC group about basic data except WBC count and examination of gallbladder by B ultrasound（P＞0.05）. But there were significant difference in operation time, blood loss, time of resumption of food, time of intestinal function recovery, length of hospital stay and complications between OC group and LC group （P＜0.01）. Conclusion Individualized treatment should be emphasized on elderly patients with acute cholecystitis. Selection of OC or LC to these patients should be based on the clinical condition and taken the safety as the first principle.
Objective To study the feasibility and curative effect of laparoscopic vs. open radical rectectomy and colectomy for colorectal cancer. Methods Sixty-two cases who underwent laparoscopic operation (17， 2， 10， 23， 9 and 1 case underwent radical right colectomy， radical transverse colectomy， radical left colectomy， Dixon， Miles and Hartmann operation respectively) and 78 cases who underwent open operation (17， 4， 11， 27， 18 and 1 case underwent radical right colectomy， radical transverse colectomy， radical left colectomy， Dixon， Miles and Hartmann operation respectively) in our department from Aug. 2001 to Jun. 2008 were included. The clinical data of patients in two groups were compared. Results There were no severe complications and death occurred in both groups and 4 cases in laparoscopic group were converted to open operation during the procedure. The mean operation time of laparoscopic group and open group were (230.6±23.5) min and (145.5±17.6) min respectively, there was a statistical difference between them (P＜0.01). The intra-operative blood loss of laparoscopic group was obviously less than that in open group 〔(135.5±22.5) ml vs. (300.6±34.5) ml， P＜0.01〕. There was no statistical difference of the number of cleared lymph nodes between two groups 〔(11.8±1.5) pieces vs. (13.3±1.7) pieces， Pgt;0.05〕. The length of distal incision margin of rectal anterior resection in laparoscopic group was obviously longer than that in open group 〔(3.1±0.4) cm vs. (2.6±0.3) cm， P＜0.01〕. The gastrointestinal and urinary function of laparoscopic group recovered more quickly than those in open group 〔(2.3±0.7) d vs. (3.6±0.9) d for intake of liquid diet， P＜0.05； (3.5±1.1) d vs. (4.7±1.2) d for intake of solid diet， P＜0.05； (2.3±0.4) d vs. (4.4±1.2) d for duration of urethral catheterization， P＜0.01， respectively〕. The length of hospital stay in laparoscopic group was shorter than that in open group 〔(8.5±0.7) d vs. (12.8±0.9) d， P＜0.01〕. But the cost of hospitalization in laparoscopic group was higher than that in open group 〔(3.14±0.25)×104 yuan vs. (2.02±0.75)×104 yuan， P＜0.05〕. There was no statistical difference of the three-year survival rate between two groups (89.5% vs. 89.1%， Pgt;0.05). Conclusion Laparoscopic radical rectectomy and colectomy for colorectal cancer is feasible and safe with minimal invasiveness.
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 investigate the reporting quality of randomized controlled trials (RCT) on laparoscopic surgery for treating colorectal disease in three SCI indexed. Methods We electronically retrieved the Ovid MEDLINE(R) from 1950 to present with Daily Updates for RCTs on laparoscopic surgery published in Diseases of the Colon amp; Rectum, International Journal of Colorectal Disease, or Colorectal Disease. The revised CONSORT statement and additional surgical items were adopted to assess the reporting quality. One point was assigned for each full description of an item, 0 for no description, and 0.5 for a partial description. Results A total of 20 RCTs were included and 8 RCTs were excluded. Their reporting quality was low. The average scores for the following items were relatively lower, 0.150 for settings where data collected; 0.250 for sample size estimation; 0.500 for sequence generation of randomization; 0.325 for allocation concealment; 0.150 for implementation; 0.475 for measurement of outcome; 0.150 for participant flow chart; 0.450 for adverse events; 0.450 for external validity; 0.400 for financial conflicts of interest; 0.250 for perioperative pharmacological treatment; 0.075 for perioperative nonphamacological treatment; 0.000 for participation of a trial methodologist; 0.350 for surgeon’s experience (years or position). Items with the lower scores were mainly in the methods and results section and surgical items. Conclusions The reporting quality of laparoscopic RCTs in these journals is low. Colorectal surgeons should rigorously evaluate reports in these journals before they apply to them in clinical practice.
Objective To evaluate the effect of laparoscopy-assisted surgery for lymph node dissection in patients with carcinoma of gastric cardia. Methods The clinical data of patients with carcinoma of gastric cardia who underwent either laparoscopy-assisted or open gastrectomy between January 2004 and September 2009 in the Department of General Surgery, the Nanchong Central Hospital were analyzed retrospectively. The number of lymph node dissection was compared. Results Thirty-nine patients underwent laparoscopy-assisted gastrectomy (laparoscopy group) and 63 patients underwent open gastrectomy (open group). There was no significant difference in preoperative complications, type of pathology or pTNM stage between two groups (Pgt;0.05). The number of lymph node dissection was 16.44±6.25 in the laparoscopy group， of which the number of first station lymph node was 10.56±3.78 (metastasis rate was 74.4%), the second station was 3.82±1.82 (metastasis rate was 46.2%), the third station was 2.00±1.36 (metastasis rate was 5.1%); in the open group, the numbers of corresponding lymph node were 16.38±5.83, 10.94±3.91 (metastasis rate was 71.4%), 3.71±1.55 (metastasis rate was 42.9%), and 1.75±1.06 (metastasis rate was 3.2%), respectively. There was no significant difference between two groups (Pgt;0.05). Conclusion The effectiveness of lymph node dissection is satisfactory by laparoscopy-assisted surgery for patients with carcinoma of gastric cardia, but prospective efficacy is still being followed up.
