Abstract
BACKGROUND It remains unclear whether laparoscopic gastrectomy with optimal lymphadenectomy is appropriate for very elderly patients with advanced gastric cancer. This study aimed to assess the validity of laparoscopic gastrectomy with D1+ lymphadenectomy performed for advanced gastric cancer in patients aged 80 years or more. METHODS Included in this retrospective study were 122 patients who underwent curative laparoscopic gastrectomy for advanced gastric cancer between 2013 and 2018. All patients over 80 years old underwent laparoscopic gastrectomy with D1+ lymphadenectomy. We divided patients by age between those who were very elderly (age ≥ 80 years; very elderly group [n = 57]) and those who were non-very elderly (age < 80 years; control group [n = 65]), and we compared patient and clinicopathological characteristics, intraoperative outcomes, and short- and long-term outcomes between the two groups. We also performed multivariate analyses to identify predictors of postoperative prognosis. RESULTS Eastern Cooperative Oncology Group Performance Status of grade 2 or higher and mean Charlson comorbidity index score and body mass index were significantly different between the very elderly group and the control group. Adjuvant chemotherapy was used in relatively few very elderly group patients. Operation time, blood loss volume, and postoperative morbidity and mortality did not differ between the two groups. The overall survival and disease-specific survival rate of very elderly group patients with the Charlson comorbidity index score of <3 was not significantly different from that of the control group patients. CONCLUSION The treatment of advanced gastric cancer by laparoscopic gastrectomy with D1+ lymphadenectomy to be both safe and effective in the very elderly group patients with the Charlson comorbidity index score of <3.

Abstract
BACKGROUND The short- and long-term efficacy of laparoscopic surgery for elderly patients with gastric cancer has not been evaluated. We aimed to use propensity score matching to clarify the efficacy of laparoscopic gastrectomy (LG) for elderly patients with gastric cancer aged ≥80 years. METHODS We retrospectively collected data from 159 consecutive patients with gastric cancer aged ≥80 years who underwent gastrectomy with curative intent at our institution between 2004 and 2015. Propensity score matching was applied to compare the open gastrectomy (OG) and LG. Short- and long-term outcomes were evaluated between the propensity-matched groups. RESULTS Patients' backgrounds and surgical factors were similar in both groups except for blood loss. The median time to first flatus was significantly shorter in the LG group than in the OG group (P = 0.002). The postoperative hospital stay was significantly shorter in the LG group (P = 0.014). The complication rate of Clavien-Dindo grade III or higher was significantly lower in the LG group (3% vs. 23%, P = 0.023). The 5-year overall survival and 5-year disease-specific survival rates were better in the LG group than in the OG group, but the differences were not significant (45% vs. 42% and 67% vs 57%, respectively). CONCLUSION LG was associated with good short-term outcomes and acceptable oncologic outcomes compared with OG in these propensity-matched patients aged ≥80 years.

Abstract
Introduction: Laparoscopic treatment of gastric cancer in elderly patients is still controversial. The aim of this retrospective study is to evaluate the safety and feasibility of laparoscopic gastrectomy in elderly gastric cancer patients based on the long- and short-term results of laparoscopic surgery. Materials and Methods: The data of 163 patients who underwent laparoscopic gastrectomy for gastric cancer. Patients were categorized into two groups by age based on World Health Organization (WHO) criteria: elderly (≥65 years, 80 cases) and nonelderly (<65 years, 83 cases). Patient characteristics and clinicopathological findings, surgical findings, short- and long-term results were compared between the two groups. Results: The patients in the study group were in the age range of 22-87 years and 80 (49%) patients were found out to be 65 years old or older. When all complications were categorized according to Clavien-Dindo (C-D) classification, >3 serious complication rates were similar between groups (P = .421). Although the length of hospital stay and the need for intensive care were higher in the elderly group, the difference was not significant (P = .066; P = .072). There was no significant difference between the two in terms of in-hospital mortality (P = .364). No statistically significant differences were found in the rates of overall survival (nonelderly group; 61.17 ± 3.34, 95% confidence interval [CI]: 54.61-67.74 versus elderly group; 56.48 ± 3.80, 95% CI: 49.03-63.93; P = .176) and disease-specific survival (nonelderly group; 64.24 ± 3.15, 95% CI: 58.06-70.40 versus elderly group; 61.93 ± 3.57, 95% CI: 54.93-68.93; P = .363) between the age groups. Conclusion: In conclusion, although laparoscopic gastrectomy is a feasible and safe method in elderly gastric cancer patients, further randomized prospective studies are needed.

Abstract
Background The benefits of laparoscopic gastrectomy (LG) in elderly gastric-cancer patients still remain unclear. The purpose of this study was to evaluate the feasibility and safety of LG in elderly gastric-cancer patients. Methods We retrospectively evaluated patients who underwent LG or open gastrectomy (OG) between June 2009 and July 2015 in a single high-volume center. We compared surgical, short-term, and long-term survival outcomes among an elderly (≥70 years old) LG (ELG) group (n = 114), a non-elderly (<70 years old) LG (NLG) group (n = 740), and an elderly OG (EOG) group (n = 383). Results Except for extended time to first flatus, the surgical and short-term outcomes of the ELG group were similar to those of the NLG group. The ELG group revealed comparable disease-specific survival (DSS) rates to the NLG group (64.9% vs 66.2%, P = 0.476), although the overall survival (OS) rate was lower (57.0% vs 65.5%, P < 0.001) in the ELG group than in the NLG group. The ELG group showed longer operation time than the EOG group (236.4 ± 77.3 vs 179 ± 52.2 min, P < 0.001). The ELG group had less estimated blood loss (174.0 ± 88.4 vs 209.3 ± 133.8, P = 0.008) and shorter post-operative hospital stay (8.3 ± 2.5 vs 9.2 ± 4.5, P = 0.048) than the EOG group. The severity of complications was similar between the ELG and NLG groups. Multivariate analysis confirmed that LG was not a risk factor for post-operative complications. Conclusions LG is a feasible and safe procedure for elderly patients with acceptable short- and long-term survival outcomes.

Abstract
PURPOSE The applicability of laparoscopic-assisted radical gastrectomy for elderly patients with gastric cancer is still not well clarified. The aim of this double-center study was to explore the feasibility and effectiveness of laparoscopic-assisted radical gastrectomy on elderly patients with gastric cancer. METHODS We prospectively collected data of patients who underwent gastrectomy for cancer in two centers from June 2016 to December 2019. Propensity score matching was performed at a ratio of 1:1 to compare the laparoscopic-assisted radical gastrectomy group and open radical gastrectomy group. Univariate analyses and multivariate logistic regression analyses evaluating the risk factors for total, surgical, and medical complications were performed. RESULTS A total of 481 patients with gastric cancer met the inclusion criteria and were included in this study. After propensity score analysis, 258 patients were matched each other (laparoscopic-assisted radical gastrectomy (LAG) group, n = 129; open radical gastrectomy (OG) group, n = 129). LAG group had lower rate of surgical complications (P = 0.009), lower rate of severe complications (P = 0.046), shorter postoperative hospital stay (P = 0.001), and lower readmission rate (P = 0.039). Multivariate analyses revealed that anemia, Charlson comorbidity index, and combined resection were independent risk factors in the LAG group, whereas body mass index and American Society of Anesthesiology grade in the OG group. CONCLUSION Laparoscopic-assisted radical gastrectomy was relative safe even effective in elderly gastric cancer patients. We should pay attention to the different risk factors when performing different surgical procedures for gastric cancer in elderly patients.

Abstract
The aim of this study was to determine whether age and comorbidity are valuable risk factors of the short-term surgical outcome after laparoscopy-assisted distal gastrectomy (LADG) in patients with adenocarcinoma. A series of 387 patients who underwent LADG at three university hospitals between March 2006 and December 2010 were retrospectively studied. To compare the short-term surgical outcomes of LADG of elderly patients with those of younger patients, patients were categorized into an elderly group (older than 70 years of age) and a younger group (70 years of age or younger). For another comparative analysis to identify risk factors of postoperative complications after LADG, patients were categorized into two groups: those with complications and those without complications. With the exception of sex ratio and comorbidity rate, two age groups were nonsignificantly different in terms of demographic, operative, pathologic, and short-term surgical outcome data. Our data support the safety and feasibility of LADG in elderly patients. However, our data show that comorbidity is an important predictor of postoperative systemic complications after LADG. Patients with an age-adjusted Charlson comorbidity index (CCI) of 3 or greater were found to be at a greater risk of developing systemic complications, which suggests that age-adjusted CCI is a useful predictor of systemic complications after LADG and that it could be used routinely for the perioperative care of aged patients with comorbidity. We recommend age-adjusted CCI be used in comparative clinical research studies on the surgical outcomes across surgeons and hospitals.

Abstract
Background Elderly patients with gastric cancer (GC) are at increased risk of infectious complications following gastrectomy. A limited set of risk factors has been identified to predict complications in these patients. To improve the safety of gastrectomy in this population, we investigated the incidence of infectious complications and associated clinicopathologic, nutritional and surgical risk factors in a cohort of elderly patients with GC. Methods Elderly GC patients (≥70 years) who underwent gastrectomy between January 2013 and December 2017 in Peking Union Medical College Hospital were included in the study. Clinicopathologic data were collected retrospectively. Severity of complications was classified using the Clavien–Dindo system. Infectious complications were assessed based on clinical diagnosis of health care-associated infection as defined by the US Centers for Disease Control and Prevention. Multivariate logistic regression analyses were performed to determine the risk factors for infectious complications. Results Three hundred thirty-one consecutive patients were included, with a median age of 74 years (range 70–88). The rate of surgical morbidity was 37.5% and the mortality rate was 1.2%. The incidence of infectious complications was 19.6%, with the most common infectious complication being pulmonary infection (11.5%). Preoperative weight loss ≥5% (odds ratio [OR] = 2.21; 95% CI, 1.15–4.28; p = 0.018), Charlson comorbidity index score ≥3 (OR = 2.83; 95% CI, 1.30–6.16; p = 0.009) and preoperative hsCRP level ≥10 mg/L (OR = 2.48; 95% CI, 1.14–5.38; p = 0.022) were independently associated with infectious complications. Conclusion Preoperative weight loss, elevated hsCRP level and comorbidity burden can be used to predict postoperative infectious complications in elderly GC patients. It is recommended to pay more attention to the treatment of elderly GC patients with these risk factors.

Abstract
PURPOSE Aging societies comprise an increasing number of elderly gastric cancer (GC) patients. We herein attempted to determine whether D2 lymphadenectomy is beneficial for older GC patients. METHODS We retrospectively analyzed a multi-institutional dataset including 3484 patients who received surgical resection for GC. For the analysis, we selected patients aged ≥ 80 years who were clinically diagnosed with T1N + or T2-4 GC. To balance the essential variables including the type of gastrectomy and the stage of progression, propensity score matching was conducted, and we compared the background clinical factors and postoperative outcomes of the patients allocated to the D2 (n = 87) and non-D2 (n = 87) dissection groups. RESULTS The D2 group had significantly longer operative times, more blood loss, and more retrieved lymph nodes (median 32 vs 24, P < 0.001) than the non-D2 group. The D2 group had a greater incidence of intra-abdominal abscesses (grade ≥ II in the Clavien-Dindo classification) than the non-D2 group (3.5% vs 0%, P = 0.040). The overall disease-specific and relapse-free survival rates of the D2 group tended to be poorer than those of the non-D2 group (hazard ratios 1.49, 1.70 and 1.14, respectively). CONCLUSIONS D2 lymphadenectomy for older patients with GC conferred little benefit regarding overall survival despite an occurrence of increased complication rates.

Abstract
Surgical site infection (SSI) is a well-known complication in older adults. However, there have been no studies on SSI after gastrectomy in older adults. Therefore, we aimed to investigate the incidence, risk factors, and outcomes of SSIs after gastrectomy in older adults.We performed a retrospective cohort study of older adults, aged 65 years or older, who underwent gastrectomy between January 2015 and December 2015 at the Severance Hospital in Seoul, Korea. The incidence and outcomes of SSIs after gastrectomy were evaluated, and the risk factors for SSI were identified using multivariate analyses.We identified 353 older adults who underwent gastrectomy. Of these, 25 patients (7.1%) developed an SSI. Multivariate analysis indicated that open surgery (odds ratio, 2.71; 95% confidence interval, 1.13-6.51; P = .03) and a longer operation time (odds ratio, 1.01; 95% confidence interval, 1.00-1.01; P = .04) were independent risk factors for SSI after gastrectomy. In the SSI group, the incidence of postoperative fever (84.0% vs 51.8%; P < .001), length of postoperative hospital stay (13 days vs 6 days; P < .001), and re-admission rates within 30 days postoperatively (32.0% vs 3.4%; P < .001) were significantly higher than those in the non-SSI group.The risk factors for SSI in older adults after gastrectomy were open surgery and a longer operation time. When an SSI occurred, the postoperative hospital stay was prolonged and the chances of having a postoperative fever and being re-admitted within 30 days increased.

Huang L, Liu H, Yu J, Lin T, Hu YF, Li TJ, Li GX. Long-Term Outcomes in Laparoscopic D2 Gastrectomy for Gastric Cancer: a Large Comprehensive Study Proposing Novel Hypotheses. J Gastrointest Surg 2019; 23:1349-1361. [PMID: 30478532 DOI: 10.1007/s11605-018-4008-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Accepted: 10/09/2018] [Indexed: 01/31/2023]
Abstract
BACKGROUND The long-term outcomes of laparoscopic gastrectomy (LG) versus open gastrectomy (OG) for gastric cancer (GC) remain obscure, especially for advanced cancer and disease affecting the upper stomach and in older patients. This study aimed to comprehensively assess the long-term efficacy of LG for GC using a large prospective database. METHODS Totally, 1877 consecutive patients (1186 receiving LG and 691 OG) operated in 2004-2016 were analyzed, with a median follow-up of 63 months. Association of LG versus OG with disease-specific survival (DSS) and disease-free survival (DFS) overall and in various subgroups were investigated using multivariable Cox regression. Propensity score matching (PSM) was performed for sensitivity analysis. RESULTS Before PSM, overall, there was no significant association of LG versus OG with survival after multivariable adjustment; however, in subgroup analyses, LG was associated with superior DSS in patients aged ≥ 70 years and those with upper GC. No significant associations regarding DFS were observed overall or in stratifications. PSM analyses revealed that LG was associated with better DSS also in patients aged ≥ 70 years (hazard ratio (HR) = 0.33, 95% confidence interval (CI) = 0.15-0.72) and in those with upper GC (HR = 0.51, 95% CI = 0.29-0.91), and with better DFS in those with upper GC (HR = 0.60, 95% CI = 0.37-0.99). Multivariable analysis showed that age, hepatitis B, performance status, tumor histology, stage, and vascular invasion were significantly associated with post-LG survival. LG-specific nomograms were then constructed with concordance indexes of 0.814 (DSS) and 0.809 (DFS) and excellent calibration. CONCLUSIONS In this large institutional analysis, while LG for GC was associated with DSS and DFS similar to those for OG overall, non-inferior LG-associated survival especially DSS was observed in some subgroups rarely investigated in prospective or randomized settings. There could still be biases even after PSM due to confounders not accounted for in this observational study. However, these findings offer novel hypotheses for further validation.

Abstract
Objective Postoperative complications adversely affected the prognosis in patients with gastric cancer. This study intends to investigate the feasibility of using machine-learning model to predict surgical outcomes in patients undergoing gastrectomy. Methods In this study, cancer patients who underwent gastrectomy at Shanghai Rui Jin Hospital in 2017 were randomly assigned to a development or validation cohort in a 9:1 ratio. A support vector classification (SVC) model to predict surgical outcomes in patients undergoing gastrectomy was developed and further validated. Results A total of 321 patients with 32 features were collected. The positive and negative outcomes of postoperative complication after gastrectomy appeared in 100 (31.2%) and 221 (68.8%) patients, respectively. The SVC model was constructed to predict surgical outcomes in patients undergoing gastrectomy. The accuracy of 10-fold cross validation and external verification was 78.17% and 78.12%, respectively. Further, an online web server has been developed to share the SVC model for machine-learning-assisted prediction of surgical outcomes in patients undergoing gastrectomy in the future procedures, which is accessible at the web address: http://47.100.47.97:5005/r_model_prediction. Conclusions The SVC model was a useful predictor for measuring the risk of postoperative complications after gastrectomy, which may help stratify patients with different overall status for choice of surgical procedure or other treatments. It can be expected that machine-learning models in cancer informatics research are possibly shareable and accessible via web address all over the world.

Abstract
OBJECTIVE The safety of minimally-invasive (MIG) and open gastrectomy (OG) in the older patients has been demonstrated in several international studies but has not been evaluated in the context of a large, Western population. The objective of this study was to evaluate the safety of gastrectomy by these two approaches among octogenarians in the United States. MATERIALS AND METHODS The National Cancer Database (2010-2014) was queried for patients with gastric adenocarcinoma who underwent MIG or OG. Disease and treatment characteristics and outcomes were compared across age groups (<65, 65-79, ≥80 years). Multivariable regression analysis was used to identify factors associated with 90-day mortality. RESULTS 13,845 patients were identified who met study inclusion criteria, of which 2140 patients (16%) were aged ≥80 years. Among octogenarians, MIG was associated with slightly decreased length of stay (11.2 vs 12.7 days, p < .001) compared to OG, with no difference in the rate of margin-positive resections, adequate lymph node sampling, or readmission (p = .30-0.77). 90-day mortality for both OG (17%) and MIG (17.2%) was significantly higher among octogenarians compared to younger patients (p < .001). Treatment at an academic facility was an independent predictor of decreased 90-day mortality among octogenarians (OR 0.534, 95%CI 0.322-0.886, p = .015). CONCLUSION In this Western population, we report comparable oncologic and post-operative outcomes between MIG and OG. However, the overall post-operative mortality rate among octogenarians remains unacceptably high. Better patient selection criteria for surgery and efforts to refer these patients to higher volume, academic facilities should be considered to improve patient outcomes.

Abstract
Purpose With increasing life expectancy, the presence of comorbidities has become a major concern in elderly patients who require surgery. However, little is known about the impact of different comorbidities on the outcomes of laparoscopic total gastrectomy (LTG). In this study, we investigated the impact of comorbidities on postoperative complications in patients undergoing LTG for gastric carcinoma. Materials and Methods We retrospectively reviewed the cases of 303 consecutive patients who underwent LTG for gastric carcinoma between 2005 and 2016. The associations between each comorbidity and postoperative complications were assessed using univariate and multivariate analyses. Results A total of 189 patients (62.4%) had one or more comorbidities. Hypertension was the most common comorbidity (37.0%), followed by diabetes mellitus (17.8%), chronic viral hepatitis (2.6%), liver cirrhosis (2.6%), and pulmonary (27.1%), ischemic heart (3.3%), and cerebrovascular diseases (2.3%). The overall postoperative morbidity and mortality rates were 20.1% and 1.0%, respectively. Patients with pulmonary disease significantly showed higher complication rates than those without comorbidities (32.9% vs. 14.9%, respectively, P=0.003); patient with other comorbidities showed no significant difference in the incidence of LTG-related complications. During univariate and multivariate analyses, pulmonary disease was found to be an independent predictive factor for postoperative complications (odds ratio, 2.14; 95% confidence interval, 1.03-4.64), along with old age and intraoperative bleeding. Conclusions Among the various comorbidities investigated, patients with pulmonary disease had a significantly higher risk of postoperative complications after LTG. Proper perioperative care for optimizing pulmonary function may be required for patients with pulmonary disease.

Abstract
BACKGROUND Evidence on short-term outcomes for GC resection in elderly patients is limited by small samples from single-institutions. This study sought to examine the association between advanced age and short-term outcomes of gastrectomy for gastric cancer (GC). METHODS Using ACS-NSQIP data, patients undergoing gastrectomy for GC (2007-2013) were identified. Primary outcome was 30-day major morbidity. Outcomes were compared across age categories (<65, 65-70, 71-75, 76-80, >80 years old). Univariable and multivariable regression was used to estimate the morbidity risk associated with age. RESULTS Of 3637 patients, 60.6% were ≥65 years old. Major morbidity increased with age, from 16.3% (<65 years old) to 21.5% (76-80 years old), and 24.1% (>80 years old) (p < 0.001), driven by higher respiratory and infectious events. Perioperative 30-day mortality increased from 1.2% (<65years old) to 6.5% (>80 years old) (p < 0.0001). After adjustments, age was independently associated with morbidity for 76-80 years of age (RR 1.31, 95% CI, 1.08-1.60) and >80 years old (RR 1.49, 95% CI, 1.23-1.81). Predicted morbidity increased by 18.6% in those 75-80 years old and 27.5% in those >80 years old (compared to <65 years old) for total gastrectomy, and by 11.6% and 17.2% for subtotal gastrectomy, for worst case scenario. Morbidity increased by 5.1% in those 75-80 years old and 7.6% in those >80 years old for total gastrectomy, and by 3.1% and 4.7% for subtotal gastrectomy, for best case scenario. CONCLUSIONS Advanced age, defined as more than 75 years, was independently associated with increased morbidity after GC resection. The magnitude of this impact is further modulated by clinical scenarios. Increased risk in elderly GC patient should be recognized and considered in indications for resection.

Abstract
PURPOSE The purpose of this study was to estimate surgical outcomes of elderly patients older than 80 years who received laparoscopic or open gastrectomy for gastric cancer and to identify risk factors for postoperative complications. METHODS Two hundred forty-two elderly patients older than 80 years underwent gastric cancer surgery between January 2010 and December 2016 in three tertiary hospitals. They were divided into two groups: laparoscopic gastrectomy (N = 59) and open gastrectomy (N = 183). The surgical outcomes and risk factors for postoperative complication were evaluated. RESULTS Among the elderly patients, 24.4% showed an ASA score of 3 or 4, and 20.7% showed a Charlson comorbidity index (CCI) score of 2 or more. 46.3% of patients had hypertension and 15.3% had diabetes. The laparoscopic gastrectomy group showed similar operation time, less intraoperative blood loss, and faster postoperative gastrointestinal recovery compared to the open gastrectomy group. The incidence of postoperative complications was 30.1% in the open group and 22.0% in the laparoscopic group (P = 0.249). One patient died for pulmonary complication in the open gastrectomy group. In multivariate analysis, older age, male, higher CCI score, and open approach were found to be correlated with increased risk for postoperative complications. CONCLUSIONS Although elderly patients over 80 years had a high incidence of comorbidity, gastric cancer surgery can be safely performed. The laparoscopic approach might be feasible for open surgery in improving quality of life in these patients, given a faster postoperative intestinal recovery period, with similar risk for postoperative complications.

Abstract
BACKGROUND Laparoscopic gastrectomy (LG) has been widely applied in patients with gastric cancer (GC). However, the safety and application value of LG in elderly patients with GC was still unclear. In this study, we aimed to evaluate the feasibility and safety of LG for elderly patients with GC using the meta-analysis. METHODS Studies comparing elderly patients and nonelderly patients who underwent LG for GC were reviewed and collected from the PubMed, EBSCO, Cochrane Library, and EMBASE. Outcomes such as operative results, postoperative recovery, and morbidity were compared and analyzed. The Review Manager 5.3 was used to portray the weighted mean difference (WMD) and odds ratio (OR) with a 95% confidence interval (CI). RESULTS Eleven observational studies with a total of 3275 patients were included. Compared with nonelderly patients, elderly patients had shorter operation time (WMD -10.46; 95% CI -17.06 to -3.86; P = .002), less retrieved lymph nodes (WMD -2.34; 95% CI -3.77 to -0.92; P = .001), delayed time to first flatus (WMD 0.31; 95% CI 0.10-0.51; P = .003), longer postoperative hospital stays (WMD 1.06; 95% CI 0.07-2.05; P = .04), higher risk for overall postoperative complication (OR 1.34; 95% CI 1.08-1.67; P = .009), nonsurgical postoperative complication (OR 1.98; 95% CI 1.24-3.15; P = .004), and postoperative pulmonary complication (OR: 3.09; 95% CI 1.68-5.68; P < .001). There was no significance between nonelderly patients and elderly patients regarding the estimated blood loss, incidences of surgical postoperative complication, surgical site infection, and ileus (P > .05). CONCLUSION Outcomes of LG for elderly patients were comparable to those in nonelderly patients. Age alone should not preclude LG in elderly patients.

Abstract
Purpose Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. Materials and Methods The estimated number of patients required for this study was 100 for a period of 18 months. Inclusion criteria were histologically proven gastric adenocarcinoma treated with laparoscopic distal or total gastrectomy and Billroth II or Roux-en-Y reconstruction. The primary endpoint was the incidence of duodenal stump leakage within the first 30 postoperative days. The secondary endpoints were early postoperative outcomes until discharge. Results One hundred patients were enrolled between February 2016 and March 2017. The study groups consisted of 65 male and 35 female patients with a mean age (years) of 62.3. Of these, 63 (63%) patients had comorbidities. The mean number of retrieved lymph nodes was 38. The mean operation time was 145 minutes including 7.8 minutes of mean LARS time. There was no occurrence of duodenal stump leakage. Thirteen complications occurred, with one case of reoperation for splenic artery rupture and one case of mortality. Conclusions Based on the results of this prospective phase II study, LARS can be safely performed in a short operation period without development of duodenal stump leakage. A future randomized prospective controlled trial is required to confirm the surgical benefit of LARS compared to non-LARS.

Abstract
PURPOSE In China, gastric cancer (GC), which is one of the most common malignant tumors, has an increasing incidence in elderly population due to aging process. Since a considerable number of elderly patients with GC accepting surgical treatments developed postoperative complications, it is necessary to evaluate risk factors for postoperative complications. MATERIALS AND METHODS In the present study, the clinicopathologic characteristics of 3,024 elderly patients (aged ≥65 years) with GC, who underwent surgery between 1996 and 2006, were examined and contributing factors for postoperative complications were analyzed. A total of 2,915 non-elderly patients (aged <65 years) with GC during the same period were enrolled as a control group. Clinicopathologic characteristics of non-elderly patients were investigated and compared with elderly group. RESULTS As to clinicopathologic characteristics, significant differences were detected in terms of location of primary lesions between elderly patients and non-elderly patients (p <.05), whereas no statistical difference was observed in other characteristics between two groups (p >.05). Surgical property and method in elderly patients were similar to that in non-elderly patients (p >.05). Regression analysis showed that diabetes, chronic pulmonary disease, preoperative anemia, preoperative hypoalbuminemia, combined organ excision, and blood transfusion were independent factors for complications in elderly patients (p <.05), with some differences from non-elderly group. CONCLUSIONS Elderly group with GC had distinctive clinicopathologic characteristics. Surgery remains principal treatment for elderly, and proper preoperative measures are required to decrease postoperative complications.

Lu J, Cao LL, Zheng CH, Li P, Xie JW, Wang JB, Lin JX, Chen QY, Lin M, Tu RH, Huang CM. The Preoperative Frailty Versus Inflammation-Based Prognostic Score: Which is Better as an Objective Predictor for Gastric Cancer Patients 80 Years and Older? Ann Surg Oncol 2016; 24:754-762. [PMID: 27807726 DOI: 10.1245/s10434-016-5656-7] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2016] [Indexed: 12/20/2022]
Abstract
BACKGROUND Due to increased life expectancy, the number of elderly patients with gastric cancer is increasing. This study was designed to determine the role of preoperative frailty (PF) as a risk factor for postoperative complications and prognosis in the oldest elderly gastric cancer patients undergoing curative resection. METHODS A total of 165 patients older than 80 years who underwent radical gastrectomy for primary gastric cancer between 2000 and 2012 were analyzed. We collected data on the inflammation-nutritional status, morbidity, and survival of these patients. The relationship between postoperative complications and PF was analyzed by logistic regression, and a Cox proportional hazards model was performed to identify the prognostic factors. RESULTS A total of 54 (32.7%) patients were considered frail. PF was associated with an increased risk for postoperative complications [odds ratio (OR) 3.396; 95% confidence interval (CI) 1.046-11.025; P = 0.042]. With a median follow-up of 37.0 (range 1.0-77.8) months, the 3 year overall survival (OS), recurrence-free survival (RFS), and cancer-specific survival (CSS) rates in the entire cohort were 46.1, 34.4, and 49.2%, respectively. A multivariate analysis of the inflammation-based prognostic factors showed that only PF was independently associated with OS (OR 1.613; 95% CI 1.052-2.473; P = 0.028), RFS (OR 1.859; 95% CI 1.279-2.703; P = 0.001), and CSS (OR 1.859; 95% CI 1.279-2.703; P = 0.001). CONCLUSIONS Frailty based on an easily calculable preoperative measure is a useful marker to identify patients at increased risk for postoperative complications and is more predictive of survival than an inflammation-based prognostic score after gastrectomy. Thus, PF status should be included in the routine assessment of the oldest elderly patients with gastric cancer.

Robotic gastrectomy for elderly gastric cancer patients: comparisons with robotic gastrectomy in younger patients and laparoscopic gastrectomy in the elderly. Gastric Cancer 2016; 19:1125-1134. [PMID: 26541766 DOI: 10.1007/s10120-015-0560-6] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Accepted: 10/18/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND Robotic surgery for gastric cancer has been adopted to overcome technical difficulties in performing laparoscopic gastrectomy. This study aimed to investigate the feasibility and safety of robotic gastrectomy in elderly gastric cancer patients. METHODS Patients who underwent laparoscopic or robotic gastrectomy from 2003 to 2010 in a single high-volume center were included in this study. We retrospectively compared preoperative characteristics, perioperative factors, and oncological parameters among an elderly (≥70 years old) robotic gastrectomy group (n = 49), a younger (<70 years old) robotic gastrectomy group (n = 321), and an elderly laparoscopic gastrectomy group (n = 132). RESULTS The elderly robotic group presented with more comorbidities than the younger robotic group. Except for number of retrieved lymph nodes (36.5 vs. 41.5; P = 0.007), short-term operative outcomes including complications and pathological parameters were comparable between the two robotic groups. The elderly robotic group showed comparable disease-specific survival to the younger robotic group although overall survival was worse. Compared to their laparoscopic counterparts, the elderly robotic group showed longer mean operation time (227 vs. 174 min). Nevertheless, the incidence and severity of postoperative complications was not different between the two elderly groups. Overall and disease-specific survival were also comparable between the elderly groups. In multivariate analysis, age and surgical approach were not risk factors for overall and major complications. CONCLUSIONS The outcomes of robotic gastrectomy in the elderly did not differ from those in younger robotic gastrectomy patients and were comparable to those in elderly patients who underwent laparoscopic gastrectomy. Thus, robotic gastrectomy could be a safe and feasible approach in elderly patients.

Abstract
BACKGROUND The number of elderly patients undergoing gastric cancer surgery has recently increased. We therefore evaluated the short- and long-term outcomes of elderly patients after curative gastrectomy. METHODS Overall, 824 patients were included in this retrospective study, which comprised of a non-elderly group (60-64 years; n = 558), an early-elderly group (75-79 years; n = 198), and a late-elderly group (≥80 years; n = 68) who underwent curative gastrectomy for gastric cancer between 2005 and 2009. Postoperative complications, according to the Clavien-Dindo classification, and survival of both elderly groups were compared with the non-elderly group. Postoperative life expectancy of the late-elderly group was compared with the corresponding aged general population. RESULTS Overall and severe (grade III or higher) complications in the early-elderly group were comparable with the non-elderly group; however, those in the late-elderly group were significantly more common than in the non-elderly group (p = 0.013 and p = 0.043, respectively). Multivariable analysis revealed that age ≥80 years was an independent risk factor for severe complications (hazard ratio 3.02, 95 % confidence interval 1.12-8.17; p = 0.029), and the disease-specific survivals of both elderly groups were comparable with the non-elderly group in all TNM stages. Postoperative life expectancy of late-elderly patients eliminating death from recurrence was comparable with the corresponding aged general population eliminating death from gastric cancer. CONCLUSIONS Gastric cancer surgery in elderly patients aged ≥80 years achieves reasonable long-term survival despite the increased risk of severe complications.

Abstract
BACKGROUND With the current increased longevity in elderly population, surgeons can expect to operate more frequently on elderly patients with both malignancies and comorbid medical conditions. This study aimed to compare the surgical and early postoperative outcomes of laparoscopy-assisted distal gastrectomy (LADG) with those of open distal gastrectomy (ODG) for gastric cancer in patients 70 years of age or older. METHODS Retrospective analysis based on a prospectively collected database of elderly patients who underwent laparoscopy-assisted distal gastrectomy or ODG from February 2013 to January 2014. Preoperative patient baseline parameters, surgical and oncological outcomes, postoperative complications and pathologic results were analyzed in this report. RESULTS Distal gastrectomy was performed for 50 patients with the age of 70 years or older, using laparoscopic surgery for 23 patients (LADG group) and open surgery for 27 patients (ODG group). The mean age of LADG group was 76.6 years and ODG group 80.0 years. The comparison between the two groups revealed statistically similar results regarding age, gender, BMI, ASA class, history of previous surgeries, CCI and pathologic characteristics. The LADG group was characterized by less intraoperative blood loss (LADG group 100 mL vs. ODG group 250 mL, P < 0.001), less narcotic use (LADG group 1 day vs. ODG group 3 days, P < 0.001), faster bowel function recovery (time to first flatus: LADG group 51.6 h vs. ODG group 67.2 h, P < 0.001; days to oral intake: LADG group 6.1 days vs. ODG group 7.9 days, P = 0.002) and shorter postoperative hospital stay (LADG group 12 days vs. ODG group 16 days, P < 0.001). There was no significant difference in postoperative complication rate (overall complication rate: LADG group 21.7 % vs. ODG group 25.9 %, P = 0.730), survival rate (P = 0.719), postoperative recurrence and metastasis rate between the patients who underwent LADG and ODG. CONCLUSIONS LADG for gastric cancer is feasible, efficacious and safe in elderly patients and may be superior to conventional open resection as regards some surgical outcomes.

Short- and Long-Term Outcomes After Laparoscopic Versus Open Total Gastrectomy for Elderly Gastric Cancer Patients: a Propensity Score-Matched Analysis. J Gastrointest Surg 2015; 19:1949-57. [PMID: 26268957 DOI: 10.1007/s11605-015-2912-2] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2015] [Accepted: 08/03/2015] [Indexed: 01/31/2023]
Abstract
BACKGROUND To date, it has been unclear whether laparoscopic-assisted total gastrectomy (LTG) was a suitable treatment for elderly patients (aged 65 years and older) with gastric cancer. The aim of the present study was to clarify the value of LTG in the elderly using a propensity score matching method. METHODS We prospectively collected data from 675 elderly gastric cancer patients who underwent total gastrectomies at our institution between January 2002 and February 2012. Propensity score matching was applied at a ratio of 1:1 to compare the LTG and open total gastrectomy (OTG) groups. The operation results, hospital courses, and survival rates were compared between the matched groups. RESULTS The LTG group had a significantly shorter mean operating time (194 vs. 267 min, P < 0.001) and significantly less intraoperative blood loss (92 vs. 204 ml, P < 0.001). The total number of collected lymph nodes was similar in the two groups. Postoperatively, the length of hospital stay was shorter in the LTG group than in the OTG group (median 14.4 vs. 16.6 days; P = 0.001); however, no significant intergroup differences were found in morbidity or mortality. Furthermore, the 3-year overall survival (OS) rate was similar between the two groups (P = 0.517). CONCLUSIONS LTG for elderly gastric cancer is feasible and safe with acceptable oncologic outcomes. Therefore, patient age alone should not be considered a contraindication in the decision between LTG and OTG treatment options. A high-volume prospective study is needed to confirm this rationale.

Abstract
Background. This study compared comorbidity-related medical care cost associated with different types of cancer, by examining breast (N = 287), colon (N = 272), stomach (N = 614), and lung (N = 391) cancer patients undergoing surgery. Methods. Using medical benefits claims data, we calculated Charlson Comorbidity Index (CCI) and total medical cost. The effect of comorbidity on the medical care cost was investigated using multiple regression and logistic regression models and controlling for demographic characteristics and cancer stage. Results. The treatment costs incurred by stomach and colon cancer patients were 1.05- and 1.01-fold higher, respectively, in patients with higher CCI determined. For breast cancer, the highest costs were seen in those with chronic obstructive pulmonary disease (COPD), but the increase in cost reduced as CCI increased. Colon cancer patients with diabetes mellitus and a CCI = 1 score had the highest medical costs. The lowest medical costs were incurred by lung cancer patients with COPD and a CCI = 2 score. Conclusion. The comorbidities had a major impact on the use of medical resources, with chronic comorbidities incurring the highest medical costs. The results indicate that comorbidities affect cancer outcomes and that they must be considered strategies mitigating cancer's economic and social impact.

Abstract
OBJECTIVE To validate the efficacy and safety of laparoscopic total gastrectomy (LTG) for advanced gastric cancer (AGC). BACKGROUND Laparoscopic distal gastrectomy (LDG) in the treatment of patients with local AGC is becoming increasingly popular, and there have been several multicenter randomized controlled trials focused on this treatment. However, few reports on the procedure of LTG for AGC exist. METHODS The data of 976 patients who underwent LTG for AGC were retrieved from a prospectively constructed database of 2170 patients who underwent laparoscopic gastrectomy between 2007 and 2013. Surgical outcomes of LTG were investigated and compared with those of patients who underwent LDG. RESULTS LTG was associated with significantly longer operation time, number of dissected lymph nodes, and time of resume soft diet compared with the LDG group. According to Clavien-Dindo classification, the morbidity and mortality rates of the LTG group were comparable to those of the LDG group. Multivariate analyses revealed that elderly patients, more comorbidities, and longer operation time were the significant independent risk factors for determining postoperative complications. The difference in overall survival rates between the two groups was statistically significant. However, a comparative analysis of overall survival showed no statistical significance for any of the stages of cancer between the LTG and LDG groups. CONCLUSIONS The study findings suggest that LTG is an oncologically safe procedure for AGC yields comparable surgical outcomes. A well-designed phase III trial can be carried out to provide valuable evidence for the oncologic safety of LTG for the treatment of AGC.

Abstract
BACKGROUND This study aimed to investigate the short-term surgical outcomes of laparoscopic gastrectomy for gastric cancer in elderly patients in order to determine the safety, feasibility, and risk factors for postoperative complications associated with this procedure. METHODS We retrospectively investigated 208 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2007 and September 2014. After excluding 15 patients with unusual medical histories or surgical treatments, 193 were selected for this cohort study. We divided the patients into two cohorts: elderly patients (≥75 years old) and non-elderly patients (<74 years old). We compared these cohorts with respect to clinicopathological characteristics and intraoperative and postoperative parameters. RESULTS The overall complication rates were 11.4% (8 of 70 patients) in the elderly cohort and 8.1% (10 of 123 patients) in the non-elderly cohort (P = 0.449). In a univariate analysis, Charlson comorbidity index (CCI) of ≥3, American Society of Anesthesiologists (ASA) score of 3, operative time of ≥330 min, and intraoperative blood loss of ≥50 ml were found to correlate significantly with postoperative complications. In a multivariate analysis, CCI of ≥3 (P = 0.034), ASA score of 3 (P = 0.019), and intraoperative blood loss of ≥50 ml (P = 0.016) were found to be independent risk factors of postoperative complications. In contrast, age was not found to significantly affect the risk of postoperative complications. CONCLUSIONS Laparoscopic gastrectomy for gastric cancer can be successfully performed in elderly patients with an acceptable complication rate. This study suggested that high CCI, ASA score, and intraoperative blood loss volume were identified as independent predictors of postoperative complications after laparoscopic gastrectomy for gastric cancer.

Surg Endosc 2014; 29:2321-30. [PMID: 25480603 DOI: 10.1007/s00464-014-3955-2] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2014] [Accepted: 10/25/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND As life expectancy is increasing, the use of minimally invasive surgery (MIS) in the elderly is gaining interest. The aim of this study was to identify the impact of minimally invasive gastrectomy by comparing the procedure to open surgery in octogenarians. In addition, we also evaluated the role of gastrectomy in elderly gastric cancer patients by assessing long-term outcomes. METHODS We retrospectively analyzed data from 99 gastric cancer patients aged 80 years or older, who underwent gastrectomy by either MIS or open surgery from 2005 to 2010. Patient characteristics, operative outcomes, pathologic results, morbidity, mortality, and follow-up data (including survival) were compared. RESULTS Thirty patients underwent gastrectomy with MIS (19 laparoscopic and 11 robotic) and 69 patients underwent open gastrectomy. MIS demonstrated significantly less blood loss, lower analgesic consumption, faster time to first flatus and soft diet, and a shorter post-operative hospital stay. Multivariate analysis revealed that the type of operation had no effect on the occurrence of complications. There were two postoperative mortalities, both in the open group. Excluding these patients, the overall and disease-specific 5-year survival rates were 57.4 and 70.0 %, respectively. The overall (MIS 70.0 %; open 52.0 %) and disease-specific (MIS 81.8 %; open 65.1 %) 5-year survival rates were similar for the two groups. When we analyzed the 85 patients underwent curative resection only, the overall (MIS 71.4 %; open 58.4 %) and disease-specific (MIS 84.1 %; open 73.6 %) 5-year survival rates were similar for the two groups. CONCLUSIONS MIS for gastric cancer may be performed safely and maintains the advantages of minimal invasiveness, even in extremely old patients. Furthermore, gastrectomy by either by MIS or open surgery can reduce gastric cancer-related deaths, even in patients 80 years or older.

Abstract
Gastric cancer is the most common cancer in Korea. Because the incidence of gastric cancer is still high even with early detection and because of developments in surgical instruments and technological advances, minimally invasive surgery has rapidly become an accepted treatment for gastric cancer in Korea. Many Korean gastric surgeons have contributed to the rapid adaptation of minimally invasive surgery for gastric cancer: not only the Korean Laparoscopic Gastrointestinal Surgery Study (KLASS) group, but also other expert surgeons after the 2000s. Thanks to their vigorous efforts involving active learning, education, workshops, academic communications, and international communications with active laparoscopic gastric surgeons in Korea, numerous results and well-designed large-scale clinical studies have been published or are actively ongoing, thus increasing its wide acceptance as an option for gastric cancer. Now, Korea has become one of the leading countries using minimally invasive surgery for the treatment of gastric cancer. This review article will summarize the current status and issues, as well as the clinical trials that have finished or are ongoing, regarding minimally invasive surgery for gastric cancer in Korea.

Abstract
BACKGROUND Elderly patients are regarded as being at increased risk during major abdominal surgery because of a lack of functional reserve and an increased number of comorbidities. The aim of this study was to compare short- and long-term outcomes of laparoscopic gastrectomy between elderly and young gastric cancer patients. METHODS Two-hundred ten patients who underwent laparoscopic gastrectomy for gastric cancer at our institution between January 2001 and December 2011 were included in this retrospective study. Patients were divided into two age groups (younger than 70 years and older than 70 years) and were evaluated with respect to postoperative morbidity, quality of life (QOL), and survival. RESULTS Postoperative morbidity was similar in elderly and young groups (18.3 vs. 21.6 %; P = 0.718). Overall survival of the elderly group was significantly worse than that of the young group (P < 0.001). However, disease-specific survival was not significantly different between the two groups. Longitudinal postoperative change in QOL in the elderly group showed a recovery similar to that in the young group. CONCLUSIONS Laparoscopic gastrectomy can be performed as safely in elderly patients as in young patients, with comparable postoperative results and long-term outcomes, including QOL, although the life expectancy of elderly patients is shorter.

Abstract
BACKGROUND Laparoscopic total gastrectomy (LTG) is a challenging surgical procedure that has substantial technical difficulties and complications. In this study, we investigated risk factors for morbidity and mortality after LTG, and the learning curve associated with postoperative morbidity. METHODS Prospectively constructed data of 203 patients undergoing LTG between 2004 and 2013 were retrospectively reviewed. The multivariate logistic regression model was used to analyze risk factors for postoperative morbidity. The Cumulative Sum (CUSUM) technique was used to assess the learning curve. RESULTS Postoperative morbidity and mortality after LTG was 18.7 and 1.5 %, respectively. Of 38 patients with postoperative morbidity, 7 (3.4 %) were managed with reoperation, 8 (4.0 %) with radiologic or endoscopic intervention, and 23 (11.3 %) with a conservative treatment. Of local complications, gastrointestinal bleeding was the most common (12 patients), followed by anastomosis leakage (9 patients) and intra-abdominal abscess (9 patients). Respiratory complication was the most common of the systemic complications. There were 17 cases (8.4 %) of complications exceeding grade III severity, of which anastomosis leakage was the most common. CUSUM analysis showed that postoperative morbidity reached a plateau after around 45 cases. Univariate and multivariate analyses revealed that old age (over 65 years of age) and surgical experience (<45 cases) were independent factors for postoperative morbidity after LTG. CONCLUSION LTG is a feasible technique with acceptable morbidity and mortality. However, substantial surgical experience is of most importance to reduce postoperative morbidity and mortality.

Abstract
BACKGROUND This study sought to identify and evaluate the risk factors of postoperative complications, prognostic factors, and appropriate surgical strategies in elderly patients undergoing surgery for gastric cancer. METHODS The medical records of 396 radical gastrectomies conducted from January 2006 to December 2011 were retrospectively reviewed. Surgical results and survival rates were assessed for 60 elderly patients (aged ≥ 80 years) and 336 non-elderly patients (aged < 80 years). The study groups were compared with respect to clinicopathological findings, surgical outcomes, and survival. RESULTS Elderly patients underwent gastrectomies with shorter operation time, showed less extensive lymphadenectomy, and had a significant difference in overall survival compared with non-elderly patients, although there was no difference in cause-specific survival among patients receiving curative resection. No significant risk factors affecting postoperative complications were identified in the elderly patients. Number of comorbidities (≥2) (HR, 5.30; 95 % CI, 1.11-25.32; P = 0.037) and TNM stage (≥II) (HR, 12.97; 95 % CI, 1.60-105.38; P = 0.017) were identified as independent prognostic factors in the elderly patients receiving curative resection. CONCLUSIONS Age is not an independent prognostic factor for patients receiving curative resection for gastric cancer. Multiple comorbidities may also influence the prognosis of elderly patients. Careful follow-up would improve overall survival for elderly patients.

Abstract
BACKGROUND Old age is regarded as the risk factor of major abdominal surgery due to the lack of functional reserve and the increased presence of comorbidities. This study aimed to evaluate the impact of old age on the surgical outcomes of totally laparoscopic gastrectomy for gastric cancer. METHODS This study enrolled 389 gastric cancer patients who underwent totally laparoscopic gastrectomy at Hanyang University Guri Hospital and ASAN Medical Center. The patients were classified into two groups according to age as those older than 70 years and those younger than 70 years. Early surgical outcomes such as operation time, postoperative complications, time to first flatus, days until soft diet began, and hospital stay were evaluated. RESULTS No patient was converted to open surgery. The two groups differed significantly in terms of overall postoperative complication rate, time to first flatus, days until soft diet began, and hospital stay. The patients who underwent Roux-en-Y gastrojejunostomy differed in incidence of postoperative ileus but not in severe postoperative complication rate. CONCLUSIONS The results of this study demonstrated that old age can have an effect on the surgical outcomes of totally laparoscopic gastrectomy. This study especially showed that elderly patients are affected by the return of bowel movement after totally laparoscopic gastrectomy. On the other hand, however, it is presumed that old age has not had a serious impact on surgical outcomes in totally laparoscopic gastrectomy because no difference in the severe postoperative complication rate was observed.

Abstract
BACKGROUND Very few reports are available on laparoscopic gastrectomy (LG) for advanced gastric cancer (AGC) patients. We therefore conducted a prospective phase II clinical trial to address the feasibility of LG in AGC. Morbidity and mortality were evaluated. METHODS The eligibility criteria were as follows: 20-80 years of age, cT2N0-cT4aN2, American Society of Anesthesiologists score of 3 or less, and no other malignancy. A total of 204 patients were enrolled onto this study. Of these, 16 were excluded because far-advanced stages of disease were identified after laparoscopic exploration, and 31 were excluded because early gastric cancer was diagnosed postoperatively. All patients underwent a D2 lymphadenectomy. Morbidity was stratified according to the Clavien-Dindo classification. RESULTS Conversion to open surgery occurred in 11 patients (7.0 %). The mean hospital stay was 6.3 days for distal gastrectomy and 8.5 days for total gastrectomy. The mean number of collected lymph nodes was 52.7 for distal gastrectomy and 63.8 for total gastrectomy. The rates of local and systemic complications of grade II or more were 8.3 and 3.2 %. One patient died of operative complications. In multivariate analysis, old age (>70 years) was an independent risk factor for complications, and old age and Billroth I anastomosis were predictable risk factors for local complications. CONCLUSIONS LG with D2 lymphadenectomy was safe and technically feasible for the treatment of AGC, with acceptable rate of morbidity and mortality. ClinicalTrial.gov REGISTRATION NCT01441336.

Abstract
A randomized controlled trial to evaluate the long-term outcomes of laparoscopic distal gastrectomy for gastric cancer is currently ongoing in Korea. Patients with cT1N0M0-cT2aN0M0 (American Joint Committee on Cancer, 6th edition) distal gastric cancer were randomized to receive either laparoscopic or open distal gastrectomy. For surgical quality control, the surgeons participating in this trial had to have performed at least 50 cases each of laparoscopy-assisted distal gastrectomy and open distal gastrectomy and their institutions should have performed more than 80 cases each of both procedures each year. Fifteen surgeons from 12 institutions recruited 1,415 patients. The primary endpoint is overall survival. The secondary endpoints are disease-free survival, morbidity, mortality, quality of life, inflammatory and immune responses, and cost-effectiveness (ClinicalTrials.gov ID: NCT00452751).

Abstract
PURPOSE With an increase in life expectancy, more elderly patients are presenting with gastric cancer. As a result it is yet be resolved whether laparoscopy assisted distal gastrectomy is a suitable treatment for elderly patients with early gastric cancer. This study retrospectively compared surgical outcomes of laparoscopy assisted distal gastrectomy between elderly and nonelderly patients with gastric cancer. MATERIALS AND METHODS The study group was comprised of 316 patients who underwent laparoscopy assisted distal gastrectomy between April 2005 and December 2010. Of these patients, 93 patients whose ages were 65 years or more were compared with 223 patients who were younger. RESULTS There were no differences in the short term outcome or minor complication rate between the elderly patients and the nonelderly patients. The hospital stay was significantly longer and the major complication rate was significantly higher for the elderly patients compared with nonelderly patients. CONCLUSIONS Laparoscopy assisted distal gastrectomy for early gastric cancer in the elderly patients had comparable operation time and blood loss with the nonelderly group. However, the safety and advantage of laparoscopy assisted distal gastrectomy in the elderly patients need to be further studied in higher volume trials.

Abstract
Laparoscopic surgery gained significant popularity in the last two decades. In our department, laparoscopic gall bladder, hernia and large bowel surgeries are the most frequent ones. Recently we started to do laparoscopic surgery for early gastric cancer, too. Initially, wedge resections, distal gastrectomy and laparoscopically asssisted periventricular lymphadenectomies were carried out. Later on, laparoscopic subtotal gastrectomy was also done. Therefore, we can provide three different ways of surgical treatment for gastric malignancies by now: wedge resection, intramucosal resection as well as subtotal gastrectomy. Four laparoscopic gastrectomies were carried out with D1 or D2 lypmhadenectomy - in case it was needed - in our department by the end of 2010. All patients' gastric cancer was less than 3 cm in size, and it was verified by preoperative histology (adenocarcinoma, T1b/N0/M0 or T2/N0/M0). The cancers were localized in the antrum or distally in the peripyloric region, and were ulcerated frequently. Subtotal gastrectomy with retrocolic gastroentero anastomosis was carried out in every case.Patient's age was not considered in patient selection. Surgical time was between two and four hours. We discuss our experience with laparoscopic gastric surgery and recommend its incorporation into practice.

Abstract
Laparoscopic surgery in Korea increased rapidly because of the early detection of gastric cancer by the development of diagnostic tools and nationwide screening. The Korean Laparoscopic Gastrointestinal Surgery Study Group (KLASS group) played a leading role in various projects related with minimally invasive surgery. The justification of minimally invasive procedures including robotic surgery, sentinel-node biopsy, or single-port surgery/Natural Orifice Transluminal Endoscopic Surgery (NOTES) must be predetermined by the clinical trial before a wide application, and the medical industry as well as surgeons should have great responsibility.

Abstract
The laparoscopic surgery in gastric cancer is applied with increasing frequency nowadays; noticeable reports come mainly from Korea and Japan with satisfactory results. This review presents briefly the issue by evaluating its role. A PubMed search of relevant articles published up to 2010 was performed to identify current information. Most data come from Far East, where gastric cancer occurs more often, and the proportion of early gastric cancer is high. Laparoscopic approach includes both the diagnostic laparoscopy and laparoscopic resection. Laparoscopic gastrectomy has currently limited application for gastric cancer in the West; it is not widely accepted and raises important considerations necessitating the planning of multicentre randomised control trials based mainly on the long-term results.

Abstract
Laparoscopic gastrectomy was begun in 1995 in Korea. But, there was 4 years gap to reactivate in 1999. High incidence of gastric cancer and increasing proportion of early cancer through national screening program along with huge effort and enthusiasm of laparoscopic gastric surgeon, and active academic exchange with Japanese doctors contributed development of laparoscopic gastrectomy in Korea. Study group activity of Korean Laparoscopic Gastrointestinal Surgery Study (KLASS) group and Collaborative Action for Gastric Cancer (COACT) group were paramount to evoke large scale multicenter clinical study and various well performed clinical studies. This review encompasses mainly international publications about this area so far in Korea.

Abstract
Purpose Gastric cancer has a high incidence and mortality rate in Korea. Despite a growing older population and an increase in the number of older patients with gastric cancer, the older patients are not willing to undergo surgery due to their operative risks. Hence, to determine the clinical characteristics and outcomes of gastric cancer surgery for them, we investigate factors influencing the treatment decision. Materials and Methods Between January 1996 and December 2005, a total of 1,519 patients were classified into two groups; the younger age group between 41 and 69 years of age, and the older age group of 70 years or older. The analysis conducted included patient characteristics, accompanying disorders, related American Society of Anesthesiologists (ASA) grade, pathological characteristics and survival rate for each age group. Results Significant differences were found in the ASA grade (P<0.001) and the number of accompanying disorders (P<0.001) between the two groups. The average length of hospital stay after surgery was 14.5 days in the younger age group, and 13.3 days in the older age group (P=0.065). The average survival time was 47.5 months in the younger age group, and 43.2 months in the older age group (P<0.001). Conclusions This study demonstrated that there was more number of accompanying disorders with a high surgical risk in the older age group. However, there was no significant difference between the older and younger age groups in terms of the incidence of complications, under the given disease conditions and if proper management was provided.

Abstract
Elderly patients constitute the largest group in oncologic medical practice, despite the fact that in solid cancers treated operatively, many patients are denied standard therapies and where such decision making is based solely on age. The “natural” assumptions that we have are often misleading; namely, that the elderly cannot tolerate complex or difficult procedures, chemotherapy, or radiation schedules; that their overall predictable medical health determines survival (and not the malignancy); or that older patients typically have less aggressive tumors. Clearly, patient selection and a comprehensive geriatric assessment is key where well-selected cases have the same cancer-specific survival as younger cohorts in a range of tumors as outlined including upper and lower gastrointestinal malignancy, head and neck cancer, and breast cancer. The assessment of patient fitness for surgery and adjuvant therapies is therefore critical to outcomes, where studies have clearly shown that fit older patients experience the same benefits and toxicities of chemotherapy as do younger patients and that when normalized for preexisting medical conditions,that older patients tolerate major operative procedures designed with curative oncological intent. At present, our problem is the lack of true evidence-based medicine specifically designed with age in mind, which effectively limits surgical decision making in disease-based strategies. This can only be achieved by the utilization of more standardized, comprehensive geriatric assessments to identify vulnerable older patients, aggressive pre-habilitation with amelioration of vulnerability causation, improvement of patient-centered longitudinal outcomes, and an improved surgical and medical understanding of relatively subtle decreases in organ functioning, social support mechanisms and impairments of health-related quality of life as a feature specifically of advanced age.

Abstract
PURPOSE Curative surgery for patients with advanced or even early gastric cancer can be defined as resection of the stomach and dissection of the first and second level lymph nodes, including the greater omentum. The aim of this study was to evaluate the short- and long- term outcomes of partial omentectomy (PO) as compared with complete omentectomy (CO). MATERIALS AND METHODS Seventeen consecutive open distal gastrectomies with POs were initially performed between February and July in 2006. The patients' clinicopathologic data and post-operative outcomes were retrospectively compared with 20 patients who underwent open distal gastrectomies with COs for early gastric cancer in 2005. RESULTS The operation time in PO group was significantly shorter than that in CO group (142.4 minutes vs. 165.0 minutes, p=0.018). The serum albumin concentration on the first post-operative day in PO group was significantly higher than CO group (3.8 g/dL vs. 3.5 g/dL, p=0.018). Three postoperative minor complications were successfully managed with conservative treatment. Median follow-up period between PO and CO was 38.1 and 37.7 months. All patients were alive without recurrence until December 30, 2009. CONCLUSION PO during open radical distal gastrectomy can be considered a more useful procedure than CO for treating early gastric cancer. To document the long-term technical and oncologic safety of this procedure, a large-scale prospective randomized trial will be needed.

Abstract
Laparoscopy-assisted distal gastrectomy for gastric cancer was first reported by Kitano et al. in 1991. Laparoscopic wedge resection (LWR) and intragastric mucosal resection (IGMR) were quickly adapted for gastric cancer limited to the mucosal layer and having no risk of lymph node metastasis. Following improvements in endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), the use of LWR and IGMR for these indications decreased, and patients with gastric cancer, including those with a risk of lymph node metastases, were more likely to be managed with laparoscopic gastrectomy (LG) with lymph node dissection. Many retrospective comparative trials and randomized-controlled trials (RCT) have confirmed that LG is safe and feasible, and that short-term outcomes are better than those of open gastrectomy (OG) in patients with early gastric cancer (EGC). However, these trials did not include a satisfactory number of patients to establish clinical evidence. Thus, additional multicenter randomized-controlled trials are needed to delineate significantly quantifiable differences between LG and OG. As laparoscopic experience has accumulated, the indications for LG have been broadened to include older and overweight patients and those with advanced gastric cancer. Moreover, advanced techniques, such as laparoscopy-assisted total gastrectomy, laparoscopy-assisted proximal gastrectomy, laparoscopy-assisted pylorus-preserving gastrectomy (PPG), and extended lymph node dissection (D2) have been widely performed.In the near future, sentinel node navigation and robotic surgery will become additional options in minimally invasive surgery (MIS) involving LG. Such developments will improve the quality of life of patients following gastric cancer surgery.

Abstract
Gastric cancer is most common cancer in Korea. Surgery is still the main axis of treatment. Due to early detection of gastric cancer, the innovation of surgical instruments and technological advances, gastric cancer treatment is now shifting to a new era. One of the most astonishing changes is that minimally invasive surgery (MIS) is becoming more dominant treatment for early gastric cancer. These MIS are represented by endoscopic resection, laparoscopic surgery, robotic surgery, single-port surgery and natural orifice transluminal endoscopic surgery. Among them, laparoscopic gastrectomy is most actively performed in the field of surgery. Laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer (EGC) has already gained popularity in terms of the short-term outcomes including patient's quality of life. We only have to wait for the long-term oncologic results of Korean Laparoscopic Gastrointestinal Surgery Study Group. Upcoming top issues following oncologic safety of LADG are function-preserving surgery for EGC, application of laparoscopy to advanced gastric cancer and sentinel lymph node navigation surgery. In the aspect of technique, laparoscopic surgery at present could reproduce almost the whole open procedures. However, the other fields mentioned above need more evidences and experiences. All these new ideas and attempts provide technical advances, which will minimize surgical insults and maximize the surgical outcomes and the quality of life of patients.

Abstract
BACKGROUND This study aimed to determine the appropriate extent of lymph node (LN) dissection in gastric cancer by analysing LN metastasis patterns from prospectively collected topographical data on nodal status at Seoul National University Hospital, Korea. METHODS The metastasis rate for each LN station was analysed according to the depth of tumour invasion in patients with primary lower-third gastric cancer who underwent curative gastrectomy. The Maruyama Index of unresected disease (MI) was calculated using the WinEstimate(®) program with simulation of various extents of LN dissection. RESULTS LN metastasis in mucosal cancer was rare; 2·6 per cent of patients had a MI of more than 5 with simulation of D1 plus station 7 dissection, whereas 0·9 per cent had a MI above 5 with D1 plus stations 7 and 8a. In submucosal cancer, 3·3 per cent of tumours metastasized to level 2 LN stations outside the range of D1 plus stations 7, 8a and 9. The proportion of patients with a MI above 5 was 9·0 per cent with D1 plus stations 7, 8a and 9 dissection. The nodal metastasis rate was higher at level 1 and 2 for muscularis propria or deeper cancers. CONCLUSION D1 dissection plus stations 7 and 8a for mucosal cancer, and D2 dissection for cancers of the muscularis propria or deeper seems appropriate. For submucosal cancer, an expanded dissection to the D2 level should be considered to ensure complete removal of metastatic LNs.

Abstract
INTRODUCTION Laparoscopic gastrectomy is rapidly expanding despite reservations by some surgeons regarding its safety and radicality. The aim of this study was to evaluate patients undergoing laparoscopic gastrectomy for both benign and malignant disease with particular emphasis on technical feasibility, safety, effectiveness and complications. PATIENTS AND METHODS Review of prospectively collected data of patients who underwent laparoscopic gastrectomy from May 2005 to September 2009 under the care of one consultant surgeon. RESULTS A total of 61 laparoscopic gastrectomies were performed (35 men and 26 women) with a median age of 68 years (range, 41-90 years). There were 39 distal gastrectomies (19 adenocarcinoma, 6 gastrointestinal stromal tumour [GIST], 4 benign gastric outlet obstruction, 4 high-grade dysplasia in gastric adenomas, 4 non-healing ulcers, 2 gastric antral vascular ectasia [GAVE]); 15 sub-total gastrectomies (13 adenocarcinomas, 2 GIST); and 7 total gastrectomies (5 adenocarcinomas, 1 GIST, 1 carcinoid). Median follow-up was for 48 months (range, 1-72 months). There was one death, two major and six minor complications. All patients with complications made a satisfactory recovery. CONCLUSIONS Laparoscopic gastrectomy is associated with a low mortality (1.75%) and major morbidity (3.50%). Although technically demanding, especially when a D2 lymphadenectomy is performed, our results have shown that tailored laparoscopic resection based on tumour characteristics with either D1 or D2 lymphadenectomy results in good surgical and oncological outcomes.
