Objective: The goal of this study was to investigate the feasibility, safety, and associated survival outcomes of laparoscopy-assisted distal gastrectomy (LADG) with lymph nodes dissection for gastric cancer. Methods: we analyzed the clinical data from 64 consecutive patients with gastric cancer who received LADG at our department of abdominal emergency surgery-Hue central hospital from January of 2007 to January of 2013. Results: LADG was successfully carried out in 62 patients; 2 cases were converted to open surgery. The mean operation time was 210 minutes (150-300 minutes), and mean number of dissected lymph nodes was 13 (5-25). The average length of hospital stay were 9,1 days (7-16 days). The morbididity and mortality was 15% and 1,5%. A total of 62 patients were followed for a subsequent 6-71 months (median, 24 months). The 3-year disease-free survival (DFS) and overall survival (OS) rates were 71,3% and 83,2%, respectively. When divided by stage, the 3-year DFS for stage I, II, and III were 88%, 84,9%, and 41%, respectively; and the 3-year OS for stage I, II, and III were 100%, 86%, and 45%, respectively. Conclusion: In this preliminary report, LADG was found to be a safe, feasible, and efficacious procedure for the treatment of gastric cancer with encouraging 3-year overall and stage-by-stage survival rates

Objectives. To investigate the prognostic impact of the number of dissected lymph nodes (LNs) in gastric cancer after curative distal gastrectomy.Methods. The survival of 634 patients who underwent curative distal gastrectomy from 1995 to 2004 was retrieved. Long-term surgical outcomes and associations between the number of dissected LNs and the 5-year survival rate were investigated.Results. The number of dissected LNs was one of the most important prognostic indicators. Among patients with comparable T category, the larger the number of dissected LNs was, the better the survival would be (). The linear regression showed that a significant survival improvement based on increasing retrieved LNs for stage II, III and IV (). A cut-point analysis yields the greatest variance of survival rate difference at the levels of 15 LNs (stage I), 25 LNs (stage II) and 30 LNs (stage III).Conclusion. The number of dissected LNs is an independent prognostic factor for gastric cancer. To improve the long-term survival of patients with gastric cancer, removing at least 15 LNs for stage I, 25 LNs for stage II, and 30 LNs for stage III patients during curative distal gastrectomy is recommended.

Abstract Background Robotic distal gastrectomy (RDG) has been increasingly used for the treatment of gastric cancer (GC). However, whether RDG has a clinical advantage over laparoscopic distal gastrectomy (LDG) is yet to be determined. Thus, this study aimed to assess the feasibility and safety of RDG for the treatment of GC as compared with LDG. Methods In total, 157 patients were enrolled between February 2018 and August 2020 in this retrospective study. We then compared the surgical outcomes between RDG and LDG using propensity score-matching (PSM) analysis to reduce the confounding differences. Results After PSM, a clinicopathologically well-balanced cohort of 100 patients (50 in each group) was analyzed. The operation time for the RDG group (350.1 ± 58.1 min) was determined to be significantly longer than that for the LDG group (257.5 ± 63.7 min; P < 0.0001). Of interest, there was a decreased incidence of pancreatic fistulas and severe complications after RDG as compared with LDG (P = 0.092 and P = 0.061, respectively). In addition, postoperative hospital stay was statistically slightly shorter in the RDG group as compared with the LDG group (12.0 ± 5.6 vs. 13.0 ± 12.3 days; P = 0.038). Conclusions Our study confirmed that RDG is a feasible and safe procedure for GC in terms of short-term surgical outcomes. A surgical robot might reduce postoperative severe complications and length of hospital stay.

7514 Background: Total number of lymph-nodes has recently proven prognostic in early breast and colorectal cancer. In this study we retrospectively evaluated the prognostic impact of the number of resected and involved lymph-nodes on the survival of stage I-III NSCLC. Methods: A series of 928 consecutive NSCLC pts who underwent complete lobectomy, bilobectomy or pneumonectomy with lymph-nodes dissection from 1/2000 to 11/2007 at Tokyo Medical University was eligible. Log rank and Cox proportional hazard model was used to estimate survival rates and relative risks. Results: Demographics are as follows: median age: 65.0 (22–87yrs), sex: 547 males and 381 females, median follow-up time: 2.5 yrs, clinical stage: 765 stage I, 84 stage II and 76 stage III, histology: 684 adenocarcinoma, 182 squamous cell carcinoma, and 62 others, operation: 870 lobectomy, 42 bilobectomy and 16 pneumonectomy, mean number of resected LN: 15 (1–49), mean number of involved LN: 0.9 (0–22). We observed a statistically significant increasing trend in overall survival (OS) between 0–3 and 4 and more of number of involved LN (P<0.001). Although a significant increasing in OS of 0–9 of number of resected LN cases compared with 10 and more was observed in all stages (P=0.024), no significant differentiation was observed in clinical stage I cases. Conclusions: This data suggests that there is a significant decrease in OS with 10 and more number of resected LN examined at surgery in NSCLC pts. However, there is no significant different in stage I pts, which implies that selected LN sampling is enough in clinical stage I cases. Further study such as LN dissection vs LN sampling in clinical stage I will be needed. No significant financial relationships to disclose.

Objective.The study was designed to explore the prognostic value of examined lymph node (LN) number on survival of gastric cancer patients without LN metastasis.Methods.Between August 1995 and January 2011, 300 patients who underwent gastrectomy with D2 lymphadenectomy for LN-negative gastric cancer were reviewed. Patients were assigned to various groups according to LN dissection number or tumor invasion depth. Some clinical outcomes, such as overall survival, operation time, length of stay, and postoperative complications, were compared among all groups.Results.The overall survival time of LN-negative GC patients was50.2±30.5months. Multivariate analysis indicated that LN dissection number(P<0.001)and tumor invasion depth(P<0.001)were independent prognostic factors of survival. The number of examined LNs was positively correlated with survival time(P<0.05)in patients with same tumor invasion depth but not correlated with T1 stage or examined LNs>30. Besides, it was not correlated with operation time, transfusion volume, length of postoperative stay, or postoperative complication incidence(P>0.05).Conclusions.The number of examined lymph nodes is an independent prognostic factor of survival for patients with lymph node-negative gastric cancer. Sufficient dissection of lymph nodes is recommended during surgery for such population.

In this study, we try to compare the benefit of laparoscopic versus open operative procedures.Patients and Methods. One hundred and sixteen patients underwent laparoscopic liver resection (LR) and another 208 patients went for open liver resection (OR) for hepatocellular carcinoma (HCC). Patients' selection for open or laparoscopic approach was not randomized.Results. The CLIP score for LR and OR was 0.59 ± 0.75 and 0.86 ± 1.04, respectively, (). The operation time was 156.3 ± 308.2 and 190.9 ± 79.2 min for LR and OR groups, respectively. The necessity for blood transfusion was found in 8 patients (6.9%) and 106 patients (50.9%) for LR and OR groups. Patients resumed full diet on the 2nd and 3rd postoperative day, and the average length of hospital stay was 6 days and 12 days for LR and OR groups. The complication rate and mortality rate were 0% and 6.0%, 2.9% and 30.2% for LR and OR groups, respectively. The 1-yr, 3-yr, and 5-yr survival rate was 87.0%, 70.4%, 62.2% and 83.2%, 76.0%, 71.8% for LR and OR group, respectively, of non-significant difference. From these results, HCC patients accepted laparoscopic or open approach were of no significant differences between their survival rates.

Abstract Background: Few studies on the comparison among robotic, laparoscopic, and open gastrectomy had been reported in gastric cancer . The goal of this study was to evaluate the advantages of robotic-assisted gastrectomy (RAG) by comparing with laparoscopic-assisted gastrectomy(LAG) and open gastrectomy (OG). Methods: 147 gastric cancer patients who underwent gastrectomy were enrolled and retrospectively analyzed between January 2017 and July 2019. Short-term outcomes such as operation time, intraoperative estimated blood loss(EBL),number of retrieved lymph nodes, postoperative recovery, learning curve, and long-term outcome such as overall survival(OS) was compared among RAG, LAG and OG groups. Results: RAG group included 47 patients, 44 in the LAG, and 61 in the OG. Basic information such as gender, age, BMI, ASA degree were similar among three groups, and there were no statistically significances in pathological TNM staging, tumor resection extent, resection margin, methods of reconstruction( P ＞0.05). The cumulative sum(CUSUM) method showed that learning curve of RAG reached stability after 17 cases . For short-term outcomes, the RAG group had the shortest EBL( P =0.033), the shortest time to first flatus( P ＜0.001), shortest time to first intake liquid diet ( P =0.004),shortest postoperative hospital stay ( P =0.023)and the largest number of retrieved lymph nodes( P =0.044),the longest operation time( P ＜0.001), the most expensive treatment cost( P ＜0.001),however, there were no significant differences in postoperative drainage, postoperative white blood cell(WBC)count and early complications among three group( P ＞0.05). In addition to long-term outcome, similar OS was observed in three groups. Conclusion: Compared with LAG and OG, RAG has certain advantages in short-term outcomes and is a safe and reliable surgical method. But still need further prospective, multi-center research to confirm this.

Abstract Background A complete dissection of infrapyloric lymph nodes is the key to a curative gastrectomy, which can be sometimes technically challenging in laparoscopic surgery. Methods One hundred and eighteen patients with gastric cancer undergoing laparoscopic gastrectomy with D2 lymphadenectomy in which the infrapyloric lymph nodes were dissected through the right bursa omentalis approach were included. The clinicopathologic characteristics and surgical outcomes were analyzed retrospectively. Results The laparoscopic gastrectomy with D2 lymphadenectomy was successful in all 118 patients with no open conversion. The mean operation time was 246.6 ± 45.7 min. The mean estimated blood loss was 87.0 ± 35.9 mL. Postoperative complications occurred in 17.8% of the patients, which were treated successfully with conservative therapy or aspiration in all. There were no No.6 lymphadenectomy-associated complications, such as injury of transverse colon, vessels of mesocolon, pancreas or duodenum, no pancreatitis, pancreatic leakage or postoperative hemorrhage. The mean postoperative hospital stay was 9.6 ± 3.7 days. On average, the total lymph nodes harvested were 36.8 ± 12.9, in which the ones from the infrapyloric area were 5.1 ± 3.1. Conclusion Laparoscopic dissection of infrapyloric lymph nodes through the right bursa omentalis approach seems to be feasible and safe, facilitating a more complete No.6 lymphadenectomy for gastric cancer.
