【Abstract】Objective To study the clinical application of laparoscopic operation. Methods The clinical findings from 13 840 cases of laparoscopic surgery in this hospital from 1992 to 2005 were reviewed retrospectively.Results Laparoscopic operation were performed successfully in 13 653（98.6%）,187 cases were transferred to open operation. Complications were occurred in 115 cases, including common bile duct injury in 3 cases. Combined treatment with laparoscope and endoscope were performed in 162 cases. Eleven thousand three hundred and fiftytwo patients had been succeeded in followup survey. Over 90.0 percent of patients recovered smoothly. Conclusion Laparoscopic operation may be applied in a more extensive scope. The major complications can be reduced by strict procedures of laparoscopic operation. The combined treatment of laparoscope and endoscope should be further studied and widely used.
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 compare the short-term outcome of 3-port and 5-port laparoscopic assisted radical resection for middle and high rectal cancer.MethodsWe retrospectively analyzed the clinical characteristics of 67 patients with middle and high rectal cancer who were treated in the Gastrointestinal Ward of Center of General Surgery in General Hospital of Western Theater Command of the Chinese People’s Liberation Army from January 2018 to December 2018. The operative, pathological, recent postoperative related indicators, and follow-up results of the two groups were compared and analyzed.ResultsAmong all the enrolled patients, 33 cases received 3-port laparoscopic surgery (3-port group) and 34 cases received 5-port laparoscopic surgery (5-port group). The total length of incision and the pain score of the Visual Analog Scale (VAS) on the 3rd postoperative day of the 3-port group were significantly better than those of the 5-port group (P<0.05). Peripheral incisal margins were negative in both two groups. However, there were no statistically significant differences in indicators such as operative time, intraoperative blood loss, operative conversion rate, hospitalization expenses, length of the distal margins, number of positive lymph nodes, number of lymph nodes harvested, time to the first flatus, time to the first ambulation, time to urinary catheter removal, time to drainage tube removal, time to the first oral intake, postoperative hospital stay, and postoperative complication rate (P>0.05). Thirty cases of the 3-port group were followed up for 12–24 months (median of 19 months), as well as 29 cases of 5-port group were followed up for 12–24 months (median of 19.5 months). There were no significant differences on the incidences of intestinal obstruction, local recurrence, distant metastasis, and death between the two groups (P>0.05).ConclusionCompared with the conventional 5-port laparoscopic surgery, the 3-port laparoscopic surgery could shorten the total length of incision and reduce the surgical trauma, suggesting that it is safe and effective.
Objective The survival data of patients with colon cancer who were treated by laparoscopic-assisted surgery and open surgery three years after operation were analyzed and contrasted, which provided data to support the future treatment. Methods The 217 patients who were cured by laparoscopic-assisted surgery and 193 patients who were cured by open surgery were followed up, and the rates of local recurrence, metastasis, implantative, and survival were contrasted and analyzed. Results Three years after laparoscopic-assisted surgery and open surgery, the disease-free survival rate was 86.2% （187/217） and 85.5% （165/193）, respectively, and the overall survival rate was 91.2% （198/217） and 92.7% （179/193）, respectively, the difference between the two groups was not statistic significance（P＞0.05）. The differences of the rates of local recurrence, metastasis, and implantative between the two groups were not statistic significance（P＞0.05）. Conclusions Laparoscopic-assisted surgery is similar with open surgery in the rates of local recurrence, forward metastasis, and overall survival. So laparoscopic-assisted surgery is a safe and radical curative surgery.
ObjectiveTo summarized the clinical experience on laparoscopic radical surgery in patients with advanced distal gastric cancer. MethodsThe clinical data of 26 patients with advanced distant gastric cancer undergoing laparoscopic gastrectomy were retrospectively analyzed. ResultsLaparoscopic distal gastrectomy was performed successfully in all patients. The operation time was (283.2±27.6) min (270-450 min) and the blood loss was (178.4±67.4) ml (80-350 ml). The time of gastrointestinal function recovery was (2.8±1.2) d (2-4 d), out of bed activity time was (1.5±0.4) d (1-3 d) and liquid diet feeding was (3.5±1.4) d (3-4 d). The hospital stay was (10.0±2.6) d (7-13 d). The number of harvested lymph nodes was 11 to 34 (17.8±7.3). The distance from proximal surgical margin to tumor was (7.0±2.1) cm (5-12 cm) and the distance from distal surgical margin to tumor was (5.5±1.8) cm (4-8 cm), thus surgical margins were negative in all samples. All patients were followed up for 3-48 months (mean 18.5 months), two patients with poorly differentiated adenocarcinoma died of extensive metastasis in 13 and 18 months, respectively, and other patients survived well. ConclusionsLaparoscopic radical gastrectomy with D2 lymphadenectomy for advanced gastric cancer is safe and feasible. However, the advantage of laparoscopic technique over the conventional open surgery requires further study.
ObjectiveTo standardize the techniques for laparoscopic radical rectal resection and discuss its application prospect. MethodsThe clinical data of 433 patients who underwent laparoscopic radical rectal resections from July 2003 to December 2010 in our hospital were reviewed retrospectively, and the different surgery procedures and the development prospect were explored. ResultsFive cases (1.2%) underwent handassistant laparoscopic procedures, 412 cases (95.2%) were done by laparoscopic-assisted operation, and the specimens were taken out with transanal pull-through technique in 16 cases (3.7%). In all of them, conversion to open procedures occurred in 11 patients (2.5%), and 290 (67.0%) patients were followed-up in 1 to 6 years, average in 2.7 years. Local recurrence occurred in 7 (2.4%) patients, while distant metastasis were diagnosed in 22 （7.6%） cases, and the overall mortality was 15.9% (46/290). There was no port-site metastasis occurred. ConclusionsFour-port laparoscopic rectal resection technique is also the clinical mainstream. Standardized laparoscopic procedure for rectal resections enhances the transformation of laparoscopic skills, and makes the operation predictable. Single incision procedure and natural orifice transluminal endoscopic surgery are future direction to explore.
