Feasibility of Laparoscopy-assisted Gastrectomy for Gastric Cancer in Elderly Patients: A Case-Control Study

EAES/SAGES evidence-based recommendations and expert consensus on optimization of perioperative care in older adults

BACKGROUND

As the population ages, more older adults are presenting for surgery. Age-related declines in physiological reserve and functional capacity can result in frailty and poor outcomes after surgery. Hence, optimizing perioperative care in older patients is imperative. Enhanced Recovery After Surgery (ERAS) pathways and Minimally Invasive Surgery (MIS) may influence surgical outcomes, but current use and impact on older adults patients is unknown. The aim of this study was to provide evidence-based recommendations on perioperative care of older adults undergoing major abdominal surgery.

METHODS

Expert consensus determined working definitions for key terms and metrics related to perioperative care. A systematic literature review and meta-analysis was performed using the PubMed, Embase, Cochrane Library, and Clinicaltrials.gov databases for 24 pre-defined key questions in the topic areas of prehabilitation, MIS, and ERAS in major abdominal surgery (colorectal, upper gastrointestinal (UGI), Hernia, and hepatopancreatic biliary (HPB)) to generate evidence-based recommendations following the GRADE methodology.

RESULT

Older adults were defined as 65 years and older. Over 20,000 articles were initially retrieved from search parameters. Evidence synthesis was performed across the three topic areas from 172 studies, with meta-analyses conducted for MIS and ERAS topics. The use of MIS and ERAS was recommended for older adult patients particularly when undergoing colorectal surgery. Expert opinion recommended prehabilitation, cessation of smoking and alcohol, and correction of anemia in all colorectal, UGI, Hernia, and HPB procedures in older adults. All recommendations were conditional, with low to very low certainty of evidence, with the exception of ERAS program in colorectal surgery.

CONCLUSIONS

MIS and ERAS are recommended in older adults undergoing major abdominal surgery, with evidence supporting use in colorectal surgery. Though expert opinion supported prehabilitation, there is insufficient evidence supporting use. This work has identified evidence gaps for further studies to optimize older adults undergoing major abdominal surgery.

Laparoscopic gastrectomy versus open gastrectomy for gastric cancer in patients among octogenarians: a meta-analysis

PURPOSE

Currently, there is no consensus regarding whether super-elderly (aged > 80 years) patients are suitable candidates for laparoscopic surgery. This study aimed to analyse the short-term outcomes and oncological prognosis of laparoscopic gastrectomy in super-elderly patients with gastric cancer (GC).

METHODS

Following PRISMA and AMSTAR-2 guidelines, we searched the Web of Science, Embase, Cochrane Library, and Pubmed databases from inception until May 2024 and performed a meta-analysis. All published studies exploring the surgical outcomes and oncological prognosis of laparoscopic versus open gastrectomy in super-elderly patients with GC were reviewed. Statistical analyses were performed using RevMan 5.3.

RESULTS

A total of 1,085 studies were retrieved, eight of which were included in the meta-analysis, comprising 807 patients > 80 years of age with GC. The meta-analysis showed that compared with open gastrectomy, patients with GC > 80 years old who underwent laparoscopic gastrectomy had a longer operative time (weighted mean difference [WMD] = 30.48, p < 0.001), less intraoperative blood loss (WMD = -166.96, P < 0.001), shorter postoperative exhaust time (WMD =-0.83, p < 0.001), shorter length of stay (WMD = -0.78, p < 0.001), fewer overall complications (Odds ratio [OR] = 0.54, p = 0.003), higher 5-year overall survival rate (OR = 1.66, p = 0.03) and disease-specific survival rate (OR = 3.23, p < 0.001). Furthermore, laparoscopic gastrectomy did not significantly affect the number of lymph node dissections, the rate of D2 radical gastrectomy, major postoperative complications, or postoperative pneumonia.

CONCLUSIONS

Compared to open gastrectomy, patients with GC aged > 80 years who underwent laparoscopic gastrectomy may have better short-term outcomes. Age should not be a contraindication for minimally invasive surgery.

Laparoscopic Gastric Resection for Gastric Cancer: Is Intracorporeal Anastomosis Necessary?

BACKGROUND AND OBJECTIVE

In surgical dissection, laparoscopic approach and open techniques do not differ significantly, but there is still no consensus on how anastomosis should be performed in both cardia and distal gastric tumors. Anastomosis can be performed by laparoscopy-assisted mini-laparotomy or by intracorporeal suture techniques. In this study, we aim to present our four years of clinical experience and short-term surgical results from 133 cases in order to evaluate the necessity of laparoscopic anastomosis.

METHODS

This study was approved by Ethics Committee (No: 1-8-19, date: 14/01/2019). Patients who underwent curative resection with the diagnosis of gastric adenocarcinoma between January 2014 and January 2018 in the Ankara University Surgical Oncology Department were included in the study.

RESULTS

Of the 133 patients included in the study, 108 (81.2) were male and the mean age was 60.51 ± 12.0 years. The time of anastomosis was significantly longer in patients undergoing intracorporeal anastomosis (p = 0.021). The incidence of anastomotic leakage was significantly higher in the group undergoing intracorporeal anastomosis (p = 0.004).

CONCLUSIONS

We think that esophagojejunostomy and jejunojejunostomy anastomoses in patients undergoing total gastrectomy should be performed with intracorporeal techniques in terms of benefit risk assessment. We believe that it is more feasible to continue the case with mini laparotomy when anastomosis is reached in patients who are planned to have gastrojejunostomy. In addition, in terms of intracorporeal anastomoses and advanced laparoscopic techniques, intracorporeal anastomoses performed in gastric cancer surgery for a laparoscopist who has completed the learning curve do not appear to be very different in terms of anastomosis safety.

The safety and feasibility of laparoscopic gastrectomy for gastric cancer in very elderly patients: short-and long-term outcomes

PURPOSE

It remains unclear whether laparoscopic gastrectomy (LG) for gastric cancer is a suitable treatment for very elderly (VE) patients. We aimed to assess the safety and feasibility of LG for gastric cancer in VE patients.

METHODS

We reviewed 226 consecutive patients who underwent LG between January 2010 and December 2016. We compared VE patients (age ≥ 80, n = 38) with non-elderly patients (age ≤ 79, n = 188).

RESULTS

An ASA-PS score ≥ 2 was more common in VE group (86.8 vs. 48.9%; P < 0.01). There were no significant differences in the operating time, blood loss, postoperative hospital stay, or postoperative morbidity between the groups. The 3-year survival rate and 3-year disease-specific survival rate were lower in the VE group (53.7 vs. 85.6%; P < 0.0001, 78.5 vs. 92.4%; P = 0.0116). A univariate analysis showed that PS scores ≥ 2, Charlson comorbidity index ≥ 4, and pN stage were independent predictors of decreased overall survival rates in the VE group. A multivariate analysis showed total gastrectomy, a Charlson comorbidity index ≥ 4, and the pN stage to be independent predictors in the VE group.

CONCLUSION

LG for gastric cancer is, thus, considered to be safe for patients aged 80 years or older. Total gastrectomy, a Charlson comorbidity index ≥ 4, and the pN stage were independent risk factors for a poor prognosis in these patients.

Short- and Long-Term Outcomes after Laparoscopic Versus Open Gastrectomy for Elderly Gastric Cancer Patients: A Systematic Review and Meta-Analysis

Background: With the rapid aging of global population, the number of elderly patients with gastric cancer is increasing. This study aimed to evaluate short- and long-term outcomes after laparoscopic gastrectomy (LG) versus open gastrectomy (OG) in elderly gastric cancer patients. Materials and Methods: We searched PubMed, EMBASE, and the Cochrane library databases from January 1994 to May 2019. Surgical safety, postoperative complications, number of harvested lymph nodes, and overall survival rate were included and analyzed. The qualities of the included studies were evaluated by Newcastle-Ottawa Quality Assessment Scale. The evidence of outcomes was evaluated using the GRADE approach. The Review Manager^® 5.3 (Cochrane, London, UK) and Stata^® 14.0 (StataCorp., College Station, Texas) were used to analyze the outcomes. Results: Thirteen studies containing 4768 elderly patients with gastric cancer were included in this meta-analysis. LG was more favorable than OG in terms of overall postoperative morbidity (odds ratio [OR]: 0.56; 95% confidence interval [CI]: 0.44 to 0.70; P < .00001), the postoperative stay (standardized mean difference [SMD]: -0.56; 95% CI: -0.76 to (-0.37); P < .00001), and the number of harvested lymph nodes (SMD: 0.19; 95% CI: 0.09 to 0.29; P = .0003). No significant difference was found in anastomotic leakage rate (OR: 0.82; 95% CI: 0.59 to 1.12; P = .21), mental disease (OR: 0.79; 95% CI: 0.44 to 1.44; P = .44), or overall survival rate (P = .62) between two groups. However, in the subgroup with a cutoff age of 80 years, the anastomotic leakage rate was higher in LG (OR: 10.27; 95% CI: 1.31 to 80.35; P = .03). Conclusions: LG was more favorable than OG in the elderly patients <80 years old with gastric cancer.

Defining the Term "Elderly" in the Field of Surgery: A Retrospective Study Regarding the Changes in the Immunoinflammatory Indices During the Immediate Perioperative Period of the Elective Uncomplicated Laparoscopic Cholecystectomy

BACKGROUNDS

The term "elderly" seems to have been used as "vulnerable to various stresses" but not well defined. To define the "elderly", we investigated whether the increased age causes unfavorable changes in several immunoinflammatory indices that indicate the increased vulnerability in the surgical field.

PATIENTS AND METHODS

One-hundred forty-two patients undergoing an elective-uncomplicated laparoscopic cholecystectomy (within 60 min and without intraoperative-cholangiography, bile spillage, or open conversion) were retrospectively investigated. Before surgery, immediately after surgery, and on postoperative day (POD)1, whether the patient age correlated the following variables was examined: neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-C-reactive-protein ratio (LCR), C-reactive-protein-to-albumin ratio (CAR), and others.

RESULTS

The immunoinflammatory indices most unfavorably changed on POD1. The age correlated neither lymphocyte-to-monocyte ratio nor platelet-to-lymphocyte ratio on POD1, when NLR, LCR, and CAR showed the significant correlation with the age. Multiple regression analyses determined the following variables as the independent determinants of these 3 indices on POD1: age, intraoperative minimum body temperature ≥35.5°C (IntMinBT ≥35.5°C), maximum heart rate during POD0-1 (MaxHR) for NLR; age and IntMinBT ≥ 35.5°C for LCR; and age and MaxHR for CAR. The threshold of "elderly" was determined as 102-year-old for NLR, 94-year-old for LCR, and 97-year-old for CAR.

CONCLUSIONS

The increased age causes the unfavorable changes in early postoperative immunoinflammatory indices after the uncomplicated laparoscopic cholecystectomy. Thus, the term "elderly" can be rephrased by the term "vulnerable to various surgical stresses." The thresholds for "elderly" defined herein seem impractical. Namely, the increased vulnerability caused by the aging seems modified by the individual surgical procedures.
