Abstract
INTRODUCTION Minimally invasive techniques have shown better short term and similar oncological outcomes compared to open techniques in the treatment of gastric cancer in Asian countries. It remains unknown whether these outcomes can be extrapolated to Western countries, where patients often present with advanced gastric cancer. MATERIALS AND METHODS A pooled analysis of two Western randomized controlled trials (STOMACH and LOGICA trial) comparing minimally invasive gastrectomy (MIG) and open gastrectomy (OG) in advanced gastric cancer was performed. Postoperative recovery (complications, mortality, hospital stay), oncological outcomes (lymph node yield, radical resection rate, 1-year survival), and quality of life was assessed. RESULTS Three hundred and twenty-one patients were included from both trials. Of these, 162 patients (50.5%) were allocated to MIG and 159 patients (49.5%) to OG. A significant difference was seen in blood loss in favor of MIG (150 vs. 260 mL, p < 0.001), whereas duration of surgery was in favor of OG (180 vs. 228.5 min, p = 0.005). Postoperative recovery, oncological outcomes and quality of life were similar between both groups. CONCLUSION MIG showed no difference to OG regarding postoperative recovery, oncological outcomes or quality of life, and is therefore a safe alternative to OG in patients with advanced gastric cancer.

Abstract
BACKGROUND Minimally invasive surgery (MIS) for gastric cancer is increasingly performed. The purpose of this study is to evaluate trends in utilization of laparoscopic and robotic techniques compared to open surgery as well as utilization based on hospital volume. METHODS We used the National Cancer Database to query patients who underwent gastrectomy from 2010 to 2017 for adenocarcinoma. Regression analyses were used to determine associations between MIS and clinical factors, the trend of MIS over time, and survival. RESULTS A total of 18,380 patients met inclusion criteria. The annual rates of MIS increased for all hospital volumes, though lower volume centers were less likely to undergo MIS. MIS was associated with a shorter length of stay compared to open, and robotic gastrectomy had a higher rate of obtaining at least 15 lymph nodes and lower rate of having a positive margin. CONCLUSIONS MIS utilization for resection of gastric cancer increased over time, with robotic surgery increasing at a higher rate than laparoscopic surgery. Importantly, this occurred without increased in mortality or sacrificing adequate oncologic outcomes.

Abstract
(1) Background: The complexity of the perioperative outcome for patients with gastric cancer is not well reflected by single quality metrics. To study the effect of the surgical outcome on survival, we have evaluated the relationship between textbook outcome (TO)-a new composite parameter-and oncological outcome. (2) Methods: All patients undergoing total gastrectomy or trans-hiatal extended gastrectomy for gastric cancer with curative intent between 2017 and 2021 at our institution were included. TO was defined by negative resection margins (R0); collection of ≥25 lymph nodes; the absence of major perioperative complications (Clavien-Dindo ≥ 3); the absence of any reintervention; absence of unplanned ICU re-admission; length of hospital stay < 21 days; absence of 30-day readmission and 30-day mortality. We evaluated factors affecting TO by multivariate logistic regression. The correlation between TO and long-term survival was assessed using a multivariate cox proportional-hazards model. (3) Results: Of the patients included in this study, 52 (52.5 %) achieved all TO metrics. Open surgery (p = 0.010; OR 3.715, CI 1.334-10.351) and incomplete neoadjuvant chemotherapy (p = 0.020, OR 4.278, CI 1.176-15.553) were associated with failure to achieve TO on multivariate analysis. The achievement of TO significantly affected overall survival (p = 0.015). TO (p = 0.037, OD 0.448, CI 0.211-0.954) and CCI > 4 (p = 0.034, OR 2.844, CI 1.079-7.493) were significant factors affecting DFS upon univariate analysis. In multivariate analysis, CCI > 4 (p = 0.035, OR 2.605, CI 0.983-6.905) was significantly associated with DFS. (4) Conclusions: We identified patient- and procedure-related factors influencing TO. Importantly, achieving TO is strongly associated with improved long-term survival in gastric cancer patients and merits further focus on surgical quality improvement efforts.

Abstract
(1) Background: Hand-assisted laparoscopic total gastrectomy (LTG) for patients with gastric cancer (GC) has been established as the standard surgical treatment at our center. This study aims to quantify the learning curve for surgeons performing minimally invasive total gastrectomy at a high-volume single center. (2) Methods: One hundred and eighteen consecutive patients who underwent minimally invasive total gastrectomy between January 2014 and December 2020 at a single high-volume center were included and reviewed retrospectively. Risk-adjusted cumulative sum analysis (RA-CUSUM) was used to monitor the surgical outcomes for patients with different risks of postoperative mortality using varying-coefficient logistic regression models. Patients were ordered by the sequential number of the procedure performed and divided into two groups according to the degree of surgeon proficiency as determined by RA-CUSUM analysis (group A: 45; group B: 73 patients). Age, gender, body mass index (BMI), tumor location, pathology, and comorbidities were compared while primary endpoints comprised surgical parameters, postoperative course, and survival outcomes. (3) Results: Forty-four cases were required for the completion of the learning curve. During this time, the mean operating time decreased. Hand-assisted laparoscopic total gastrectomy performed after a learning curve was associated with a shorter median operating time (OT) (360 min vs. 289 min, <0.001), and a reduced length of stay (A = 18.0 vs. B = 14.0 days) (p = 0.154), while there was a trend toward less major complications (Clavien−Dindo (CD) 3−5 within 90 days (12 (26.67%) vs. 10 (13.70%) p = 0.079). Our results showed no difference in anastomotic leakage between the two groups (group A vs. group B, 3 (6.67%) vs. 4 (5.48%) p = 0.99). Similarly, 30-day (0 (0%) vs. 1 (1.7%), p = 0.365) and 90-day mortality (1 (2.08%) vs. 2 (3.39%), p = 0.684) were comparable. Following multivariate analysis, the level of surgical proficiency was not a significant prognostic factor for overall survival. (4) Conclusions: A minimum of 44 cases are required for experienced laparoscopic surgeons to achieve technical competence for performing LTG. While operation time decreased after completion of the learning curve, quality criteria such as achievement of R0 resection, anastomotic leakage, and perioperative mortality remained unaltered. Of note, the level of surgical training showed no significant impact on the 2 year OS or DFS.

Abstract
BACKGROUND Minimally invasive gastrectomy is currently considered a valid option to treat gastric cancer and is gaining increasing acceptance. Recent reports have suggested that the application of robots may confer some advantages over conventional laparoscopy, but the role of robotic surgery in clinical practice is still uncertain. We aimed to critically review the relevant evidence comparing robotic to standard laparoscopic surgery in performing radical gastrectomy. METHODS The Pubmed/Medline electronic databases were searched through February 2021. Paper conference and the English language was the only restriction applied to our search strategy. RESULTS According to the existing data, robotic gastrectomy seems to provide some benefits in terms of blood loss, rate of conversion, procedure-specific postoperative morbidity, and length of hospital stay. Robotic gastrectomy is also associated with a longer duration of surgery and a higher economic burden as compared to its laparoscopic counterpart. No significant differences have been disclosed in terms of long-term survivals, while the number of lymph nodes retrieved with robotic gastrectomy is generally higher than that of laparoscopy. CONCLUSIONS The current literature suggests that robotic radical gastrectomy appears as competent as the conventional laparoscopic procedure and may provide some clinical advantages. However, due to the relative paucity of high-level evidence, it is not possible to draw definitive conclusions.

Abstract
BACKGROUND Chemotherapy improves outcomes in patients with resectable gastric cancer. Minimally invasive gastrectomy (MIS) rates are increasing, though the impact of MIS on postoperative chemotherapy remains uncertain. This study examines the impact of MIS vs open gastrectomy (OG) on utilization of adjuvant chemotherapy for high-risk gastric cancer. METHODS Patients in the National Cancer Database who underwent resection for high-risk gastric adenocarcinoma between 2010 and 2015 were included. Patients were stratified by surgical approach (MIS vs OG) and analyzed using multivariable regression modeling. Primary endpoints were utilization of and time to initiation of adjuvant chemotherapy. RESULTS Overall, 23 071 patients were included; 16 595 (71.9%) underwent OG and 6476 (28.1%) underwent MIS. After adjusting for patient and tumor characteristics, MIS was not associated with increased use of adjuvant chemotherapy (odds ratio [OR]: 1.027, 95% confidence interval [CI]: 0.95 to 1.11, P = .50), and time to initiation of chemotherapy was similar (-2% change, 95% CI: -5% to +1%, P = .27). MIS was associated with shorter hospital stays (-1 day). Thirty-day readmission rates, 90-day mortality, and overall survival were similar between groups. CONCLUSIONS In this study, while MIS for gastric adenocarcinoma was associated with shorter hospital stays and comparable survival, it was not associated with improved utilization or time to initiation of adjuvant chemotherapy.

Abstract
Background. We compared the outcomes of laparoscopic-assisted (LA) and robotic-assisted (RA) gastrectomies performed for gastric adenocarcinoma in the National Cancer Database. Methods. The National Cancer Database was queried for patients 18 years old with stages I to III gastric adenocarcinoma who underwent LA or RA gastrectomy. Propensity matching was performed between the 2 groups with regard to clinical staging, adjuvant treatment, demographics, and the extent of surgery. Results. A cohort of 1893 (1262 = LA, 631 = RA) patients was identified in a 2:1 propensity matching. The groups were well matched. The rate of negative margin as well as 30- and 90-day mortality were similar between the 2 cohorts. Long-term survival was similar between the 2 groups (median survival 49.2 months in LA vs 56.2 months for RA, P = .405). However, the average number of lymph nodes (LNs) sampled was significantly higher in the RA group compared with the LA group (19.6 vs 17.4, P < .001). Similarly, the percentage of surgeries in which ≥15 LNs were sampled was also greater in the RA group compared with the LA group (63.9% vs 57.6%, P = .010). On multivariable analysis, having 15 LNs or more examined was associated with better survival (hazard ratio = 0.72, 95% confidence interval = 0.60-0.87, P < .001). Advanced age, nodal positivity, and advanced clinical stages were significantly associated with worse survival. Conclusions. RA gastrectomy may allow a greater harvest of LNs, and thus more accurate staging, without increasing short-term adverse outcomes compared with LA gastrectomy. Short-term and long-term outcomes in this well-matched cohort appear comparable for both approaches.

Abstract
BACKGROUND The aim of this study was compare short- and long-term outcomes between robotic (RG) and standard open gastrectomy (OG). METHODS This is a single-center propensity score-matched study including patients who underwent RG or OG for gastric cancer between 2008 and 2018. RESULTS In total, 191 patients could be included for analysis. Of 60 RG patients, 49 could be matched. After matching, significant differences in baseline characteristics were no longer present. Operative time was significantly longer (451 min, IQR: 392-513) in the RG group than in the OG (262 min, IQR: 225-330) (P < .0001). No significant differences in postoperative complications between RG (n = 15, 30.6%) and OG (n = 15, 30.6%) were seen (P = 1.000). Overall survival was comparable between the groups. CONCLUSIONS RG is feasible and safe. With regard to long-term oncologic outcomes, survivals in the RG group were similar to those in OG group.

Abstract
BACKGROUND Recent reports have suggested that the use of the robot might reduce the rate of pancreatic complications following minimally invasive radical gastrectomy. METHODS By meta-analyzing the available literature, we aimed to elucidate possible differences between conventional laparoscopic and robotic radical gastrectomy on pancreatic morbidity. RESULTS More than 2000 patients from eight studies were eventually included in the analysis. The overall incidence of postoperative pancreatic complications was 2.2%, being 1.7% and 2.5% following robotic and laparoscopic gastrectomy (LG), respectively. In particular, pancreatic fistula occurred in 2.7% of patients receiving robotic gastrectomy (RG) and 3.8% of patients receiving laparoscopy. CONCLUSIONS The use of the robot showed a trend toward better outcomes compared with laparoscopy, despite the presence of more advanced disease and higher body mass index. The meta-analysis resulted in an odd ratio of 0.8 favoring RG over LG on pancreatic morbidity, although without statistical significance.
