Abstract：

Objectives To compare total laparoscopic gastrectomy with intracorporeal hand-sewn Gl reconstruction and laparoscopy-assisted gastrectomy for gastric cancer. Methods Between July 2009 and July 2010, 21 patients of gastric cancer underwent total laparoscopic D2 radical gastrectomy with intracorporeal hand-sewn reconstruction and 28 did laparoscopy-assisted D2 radical gastrectomy in Xijing Hospital of Digestive Diseases. All patients were operated on by an experienced surgeon. Patient demographics, TNM stage, location of tumor, the intraoperative and postoperative details of the two groups were compared. Results In the 21 patients undergoing total laparoscopic gastrectomy, there were 15 of distal gastrectomy and 6 of total gastrectomy, compared with 21 and 7 in laparoscopy-assisted group. In total laparoscopic group, intracorporeal hand-sewn technique was used for gastro-jejunal and jejuno-jejunal (J-J)anastomosis, and 25 mm circular stapler was used for esophago-jejunal anastomosis. The operation time was significant longer in total laparoscopic group than in laparoscopy-assisted group of (279 ± 65 ) min vs.(232 ±40) min (P ＜ 0.05 ). No significant difference was observed between the two groups in proximal margin [(5.7 ± 1.5 )cm vs. (5.1 ± 1.4) cm, P ＞ 0.05] and distal margin [( 3.1 ± 0.9 )cm vs. ( 2.9 ±0.9) cm,P ＞0.05]. The iv narcotic use in laparoscopy-assisted group was 1.8 d but it was not used in total laparoscopic group. The first passing flatus was on day 3 in total laparoscopic group compared with 4.8 d in laparoscopy-assisted group. Both groups had 2 postoperative early complications, one intra-abdominal infection and one lung infection in total laparoscopic group compared with one wound infection and one lung infection in laparoscopy-assisted group. There was no anastomosis-related complications after 4 months of follow-up. Conclusions The operation time and postoperative early complication was acceptable for selected patients treated by total laparoscopic D2 radical gastrectomy with intracorporeal hand-sewn GI tract reconstruction in hands of experienced laparoscopic surgeon.

Abstract：

Objective To explore the feasibility and efficacy of laparoscopy assisted radical gastrectomy on lymph node(LN)dissection for gastric cancer and to compare it with open gastrectomy.Methods The clinical data of 934 patients with gastric cancer underwent radical resection from January 2007 to May 2010 were analyzed retrospectively. Among the patients, 506 cases received laparoscopy assisted gastrectomy(LAG group)and 428 cases received open gastrectomy(OG group). The number of retrieved LNs and the survival curve between the two groups was compared. Then, the relations between the number of dissected LNs and postoperative morbidity were analyzed. ResultsFor all patients, the mean number of dissected LNs was 29±10, there was no significantly differences between LAG group and OG group(P＜0.05). While the number of the retrieved No. 7, 8 LNs in LAG group were significantly more than those in OG group. No significant differences was found in the number of dissected LNs for the pT1-2stages tumors between the two groups, but significantly greater number of LNs was harvested by LAG group in pT3 stage(P＜0. 05). No significant differences were found in the number of dissected LNs in different gastrectomy types or extents of LN dissection between the two groups. In the first 50 cases, there were less dissected LNs in LAG group than that in OG group, while 51 cases later, there was no significantly differences in number of dissected LNS between the two groups(P＞0.05). The postoperative morbidity of LAG group and OG group was 11.1% and 20. 1%, respectively(P ＜0.05), but there was no significant correlations between the number of dissected LNs and postoperative morbidity in both groups. Conclusions With the improvement in surgical skills, laparoscopy-assisted radical gastrectomy with lymph node dissection is a safe and feasible procedure, and it is oncologically compatible with open gastrectomy. Suitable increment of dissected LN count would not increase the postoperative complication rate.     

Short-term efficacy of laparoscopy-assisted vs open radical gastrectomy in gastric cancer

AIM:To investigate the short-term benefits of laparoscopic radical gastrectomy(LARG)and open radical gastrectomy(ORG)in patients with gastric cancer.METHODS:A total of 400 patients with gastric cancer aged≤65 years who were treated at General Hospital of Lanzhou Military Region were enrolled.Among these,200 patients underwent LARG between October2008 and August 2012(LARG group);and 200 patients underwent ORG between March 2000 and September2008(ORG group).The short-term therapeutic benefits between the two groups were analyzed.RESULTS:The LARG procedure offered significantly better benefits to the patients compared to the ORG procedure,including less intraoperative blood loss(103.1±19.5 mL vs 163.0±32.9 mL,P0.0001),shorter postoperative hospital stay(6.8±1.2 d vs 9.5±1.6 d,P0.0001),less frequent occurrence of postoperative complications(6.5%vs 13.5%,P=0.02),shorter time to mobilization(1.0±0.3 vs 3.3±0.4 d,P0.0001),shorter time to bowel opening(3.3±0.7 d vs 4.5±0.7 d,P0.0001),and shorter time to normal diet(3.0±0.4 vs d 3.8±0.5 d,P0.0001).However,LARG required a longer time to complete than the ORG procedure(192.3±20.9 min vs 180.0±26.9 min,P0.0001).CONCLUSION:Compared to ORG,LARG is safer,more effective,and less invasive for treating gastric cancer,with better short-term efficacy.

Effects of laparoscopy-assisted radical gastrectomy on the expression of intercellular adhesion molecule β1 and integrin 1 in peritoneal mesothelial cells and its significance

Objective To investigate the changes of the expression of intercellular adhesion molecule-1 (ICAM-1) and integrin β1 in peritoneal mesothelial cells during laparoscopy-assisted radical gastrectomy (LARG) and to explore the possible effects of LARG on the peritoneal metastasis. Methods From April to August 2008, LARG was performed for 26 patients with gastric cancer (laparoscopy group), while 20 cases underwent open radical gastrectomy (open group). Peritoneum of right upper belly was collected at 3 operation time points (the beginning, 2 hours, 4 hours). The expressions of ICAM-1 and integrin β1 in peritoneal mesothelial cells at 3 time points were detected by immunohistochemistry. Results With the operation prolonging, the expression of ICAM-1 and integrin β1 was increased gradually in both LARG and open groups. The expression of integrin β1 in two groups was obviously increased at 4-hour time point as compared to the beginning (P<0.05). Besides, there were no significant differences of these two adhesion molecules among the three operation time points between two groups (P>0.05). Conclusions Compared with open surgery, LARG is not associated with a greater effect on the expression of ICAM-1 and integrin β1 in peritoneal mesothelial cells, and may not promote peritoneal metastasis of gastric cancer through increasing the expression of adhesion molecule in peritoneal mesothelial cells.

Laparoscopy-assisted distal gastrectomy with laparoscopic sentinel lymph node biopsy after endoscopic mucosal resection for early gastric cancer

Background There has been a trend toward minimally invasive treatment of early gastric cancer. We report the preliminary results of laparoscopy-assisted distal gastrectomy with laparoscopic sentinel lymph node biopsy after endoscopic mucosal resection. Methods Six patients underwent laparoscopy-assisted distal gastrectomy after endoscopic mucosal resection between February 2002 and October 2005 at Mie University Hospital. These patients first underwent laparoscopic sentinel lymph node biopsy and then laparoscopy-assisted distal gastrectomy with lymphadenectomy. Results No patient underwent conversion to open surgery during the operation. None of the patients had any postoperative complications. The mean length of postoperative hospital stay was 11.3 days. Sentinel lymph nodes were identified laparoscopically in five patients. There were 20 sentinel and 85 nonsentinel lymph nodes in the six patients. Postoperatively, tissue sections showed that none of the lymph nodes were metastasized. Immunohistochemistry with D2-40 antibody showed that there were normal lymphatics in the submucosal layer with mucosal defects at the endoscopic mucosal resection site. No patients had any tumor recurrence during followup. Conclusions Laparoscopy-assisted distal gastrectomy after endoscopic mucosal resection was a safe and curative procedure. Endoscopic mucosal resection before sentinel lymph node biopsy was acceptable for early gastric cancer.     

Laparoscopy-assisted Billroth I gastrectomy compared with conventional open gastrectomy

BACKGROUND: Although several studies compare surgical results of laparoscopic and open colonic resections, there is no study of laparoscopic gastrectomy compared with open gastrectomy. HYPOTHESIS: When compared with conventional open gastrectomy, laparoscopy-assisted Billroth I gastrectomy is less invasive in patients with early-stage gastric cancer. DESIGN: Retrospective review of operative data, blood analyses, and postoperative clinical course after Billroth I gastrectomy. SETTING: University hospital in Japan. PATIENTS: The study included 102 patients who were treated with Billroth I gastrectomy for early-stage gastric cancer from January 1993 to July 1999: 49 with laparoscopy-assisted gastrectomy and 53 with conventional open gastrectomy. MAIN OUTCOME MEASURES: Demographic features examined were operation time; blood loss; blood cell counts of leukocytes, granulocytes, and lymphocytes; serum levels of C-reactive protein, interleukin 6, total protein, and albumin; body temperature; weight loss; analgesic requirements; time to first flatus; time to liquid diet; length of postoperative hospital stay; complications; proximal margin of the resected stomach; and number of harvested lymph nodes. RESULTS: Significant differences (P<.05) were present between laparoscopy-assisted and conventional open gastrectomy when the following features were compared: blood loss (158 vs 302 mL), leukocyte count on day 1 (9.42 vs 11.14 x 10(9)/L) and day 3 (6.99 vs 8.22 x 10(9)/L), granulocyte count on day 1 (7.28 vs 8.90 x 10(9)/L), C-reactive protein level on day 7 (2.91 vs 5.19 mg/dL), interleukin 6 level on day 3 (4.2 vs 26.0 U/mL), serum albumin level on day 7 (35.6 vs 33.9 g/L), number of times analgesics given (3.3 vs 6.2), time to first flatus (3.9 vs 4.5 days), time to liquid diet (5.0 vs 5.7 days), postoperative hospital stay (17.6 vs 22.5 days), and weight loss on day 14 (5.5% vs 7.1%). There was no significant difference between laparoscopy-assisted and conventional open gastrectomy with regard to operation time (246 vs 228 minutes), proximal margin (6.2 vs 6.0 cm), number of harvested lymph nodes (18.4 vs 22.1), and complication rate (8% vs 21%). CONCLUSIONS: Laparoscopy-assisted Billroth I gastrectomy, when compared with conventional open gastrectomy, has several advantages, including less surgical trauma, less impaired nutrition, less pain, rapid return of gastrointestinal function, and shorter hospital stay, with no decrease in operative curability. When performed by a skilled surgeon, laparoscopy-assisted Billroth I gastrectomy is a safe and useful technique for patients with early-stage gastric cancer.     

腹腔镜辅助远端胃癌根治术学习曲线研究

目的 探讨腹腔镜辅助远端胃癌根治术的学习曲线.方法 回顾分析2010年12月-2012年12月由同一术者完成的120例腹腔镜辅助远端胃癌根治手术的临床资料.按手术先后次序分为3组（A、B、C组各40例）,比较各组术中情况（手术时间、术中出血量、淋巴结清扫总数、中转开腹例数）及术后恢复情况（肛门排气时间、术后住院时间、并发症例数）.结果 与A组相比,B、C组手术时间短[A、B、C组分别为（287.8±34.9）、（200.6±21.2）、（201.8±27.7）min,F=125 012,P=0.000],术中出血量少[A、B、C组分别为（143.8±67.2）、（68.8±27.8）、（67.5±27.2）ml,F=38.018,P=0.000],淋巴结清扫数量多[A、B、C组分别为（18.3±3.4）、（25.8±4.6）、（26.3±4.9）个,F=43.047,P=0.000].B、C组之间差异均无显著性（P〉0.05）.3组肛门排气时间、术后住院时间、并发症发生率差异无显著性（P〉0.05）.结论在进行40例手术后,可完成腹腔镜辅助远端胃癌根治手术的学习曲线.
