  • Application of Nano-Carbon Particles in Laparoscopic Operation for Adenocarcinoma of Esophagogastric Junction

    Objective To explore the feasibility and clinical effect of the nano-carbon particles in laparoscopic operation for adenocarcinoma of esophagogastric junction. Methods From 2008 to 2011, 119 patients with adenocar-cinoma of esophagogastric junction who underwent the laparoscopic operation were divided into study group (n=56) and control group (n=63). The nano-carbon particle was injected into the subserosa around the tumor using the injection needle made by ourselves for lymphatic tracing before the laparoscopic operation in the study group, while no tracer was given in the control group. The indexes of lymph nodes, operation time, intraoperative blood loss, and postoperative hospital stay were compared in two groups. Results The nano-carbon particle was injected into the subserosa around the tumor successfully in the study group. The numbers of dissected lymph nodes and metastatic lymph nodes in the study group were significantly more than those in the control group (dissected lymph nodes:20.52±4.51 versus 16.44±3.80, t=5.341,P=0.000;metastatic lymph nodes:8.88±3.15 versus 6.49±2.49, t=4.602, P=0.000). There were no statistical diff-erences in the intraoperative blood loss, operation time, and postoperative hospital stay in two groups 〔intraoperative blood loss:(97.50±27.52) ml versus (96.03±22.83) ml, t=0.318, P=0.751;operation time:(221.07±24.25) min versus (230.48±38.54) min, t=-1.570, P=0.119;postoperative hospital stay (10.82±1.67) d versus (10.29±1.33) d, t=1.945, P=0.054〕. Conclusions Injection of the nano-carbon particles using the injection needle made by ourselves is feasible in laparoscopic operation for adenocarcinoma of esophagogastric junction. It can increase number of dissected lymph nodes without increasing operation time, intraoperative blood loss, and postoperative hospital stay.

  • Effect Evaluation of Laparoscopy-Assisted Surgery for Lymph Node Dissection in Patients with Carcinoma of Gastric Cardia

    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.

  • 腹腔镜结直肠癌根治术在合并慢性阻塞性肺疾病患者中的可行性研究

    目的探讨合并慢性阻塞性肺疾病(COPD)的患者行腹腔镜结直肠癌根治术的可行性。 方法2008年10月-2012年12月74例合并COPD患者接受腹腔镜结直肠癌根治术,回顾性分析患者临床资料,统计呼吸系统相关并发症发生率,评价手术安全性。 结果术后发生肺部感染5例,切口感染2例,吻合口瘘2例,肺不张2例,无气胸、急性呼吸窘迫综合征尿路感染、深静脉血栓及肠梗阻发生无围手术期死亡;术后拔管时间(26.72±15.07)min,下床活动时间(2.18±0.91)d,排气时间(1.85±0.79)d,排便时间(4.14±1.06)d,进流质时间(2.62±0.70)d术后住院时间(10.53±1.75)d。术后随访3个月,无死亡或复发。 结论在呼吸专科医师参与下通过充分细致的围术期处理,合并COPD的患者行腹腔镜结直肠癌根治术是可行的。

  • Analysis for 76 cases of transanal total mesorectal excision and discussion on the non-patient factors affecting the quality of surgery

    ObjectiveTo analyze whether transanal total mesorectal excision (taTME) can achieve high-quality TME, explore the non-patient factors affecting the quality of taTME, improve the quality of taTME.MethodsThe clinical data of 76 patients undergoing taTME from January 2015 to September 2018 in the Department of Gastrointestinal Surgery of Nanchong Central Hospital were retrospectively analyzed. The operative time, intra-operative bleeding volume, positive rate of circumferential margin, integrity of mesorectum, positive rate of margin and complications were taken as the observation indexes of operative quality. The improvement of surgical equipment, structured training, and the accumulation of surgical cases (No. 1–25 cases was early group, No. 26–50 cases was mid-term group, No. 51–76 cases was later stage group) were compared as grouping conditions, and various factors affecting the quality of taTME were analyzed.Results① Pre- and post-the improvement of surgical equipment: compared to the pre-improvement of surgical equipment group, the distance between tumors and anal margin of patients in the post-improvement of surgical equipment was closer [(4.9±1.3) cm vs. (5.9±2.7) cm, P=0.040] and the postoperative hospital stay was shorter [(10.6±3.9) d vs. (12.4±2.7) d, P=0.023], while there were no significant difference in the amount of bleeding, the positive rate of circumferential margin, the integrity of mesorectum, the positive rate of margin and the complications in the two groups (P>0.05). ② Pre- and post-training for surgeon: compared to the pre-training group, the operative time in the post-training group was shortened [(224.6±70.2) min vs. (275±77.0) min, P=0.020], while there were no statistical differences in the amount of bleeding, the integrity of mesorectum, the difference of the positive rate of circumferential margin, the positive rate of distal margin, postoperative complications and postoperative hospital stay (P>0.05). ③ The cumulative grouping of cases: compared to the later stage group [(218.8±69.5)min], the operative time in the early group [(275.2±82.6) min] and the mid-term group [(278.8±37.5) min] were shortened with statistical difference (P=0.022, P=0.003). Moreover, compared to the early group [(12.9±2.4) d], the postoperative hospital stay in the mid-term group [(10.8±4.0) d] and the later stage group [(10.2±3.6) d] were shortened with statistical significance (P=0.032, P=0.007). However, there were no significant difference in the volume of bleeding, the positive rate of circumferential margin, the positive rate of incisal margin and the degree of mesangial integrity among the three groups (P>0.05).ConclusionstaTME can achieve high-quality TME. With the improvement of equipment, the participation of structured training and the accumulation of surgical cases, taTME achieved consistent quality in about 50 cases. The improvement of surgical equipment is the guarantee of the quality of taTME. Structured training is the key to improve the surgical quality of taTME.

  • Individualized treatment of anastomotic leakage after laparoscopic D2 radical gastrectomy

    ObjectiveTo summarize the experience in the treatment of anastomotic leakage after laparoscopic D2 radical gastrectomy.MethodThe clinicopathologic data of 11 patients with anastomotic leakage after the laparoscopic D2 radical gastrectomy in the Nanchong Central Hospital from May 2016 to January 2018 were analyzed retrospectively.ResultsAmong the 11 patients with anastomotic leakage, 3 were grade Ⅱ leakages and 8 were grade Ⅲa leakages. There were no symptoms in the 3 cases of anastomotic leakage, which were confirmed only by the gastrointestinal radiography and were healed after 7 d of conservative treatment. Among the 8 patients with the clinical symptoms, 5 cases were treated by the endoscopic drainage and negative pressure suction for 60–90 d, 3 cases were treated by the endoscopic covered stent, 2 cases were cured after 30–60 d, and 1 case died of massive bleeding after 45 d.ConclusionsDue to differences of location, time, limitation, and size of anastomotic leakage after laparoscopic D2 radical gastrectomy, individualized treatment should be performed according to specific situation of patients in local treatment. Endoluminal covered stent has certain clinical application value.
