Background Surgery with total gastrectomy and D2 lymph node dissection (LND) has been recommended as the standard treatment for patients with advanced upper and middle gastric carcinoma and/or Siewert type II/III adenocarcinoma of the esophagogastric junction (AEG). However, whether the No. 10 lymph node (No. 10 LN, also known as splenic hilar LN) should be dissected in total gastrectomy remains controversial. We aimed to evaluate whether the No. 10 LND with spleen preservation has survival benefit for patients with gastric cancer and/or AEG who underwent the total gastrectomy. Methods The PubMed, Embase, the Cochrane Library, ClinicalTrials.gov and American Society of Clinical Oncology.org (ASCO.org) were electronically searched to identify eligible studies. The primary outcome was the survival rate, and secondary outcomes included the disease-free survival (DFS) rate and side effects. The Review Manager 5.3.5 software was used for the meta-analysis. The odds ratio (OR) and mean difference with 95% confidence interval (CI) were calculated. The statistical heterogeneity was assessed using chi-square (χ 2 ) and I 2 tests. Results Eight studies enrolling a total of 4,131 patients were eligible for our review. The meta-analysis results demonstrated that the No. 10 LND group was significantly better than the non-No. 10 LND group in terms of the 3- (OR =0.71, 95% CI: 0.62–0.81, P<0.00001) and the 5-year (OR =0.66, 95% CI: 0.58–0.75, P<0.00001) survival rates but not in the 1-year survival rate (OR =0.91, 95% CI: 0.75–1.11, P=0.36). The DFS rates in the No. 10 LND group were significantly increased after 1 (OR =0.76, 95% CI: 0.61–0.93, P=0.008), 3 (OR =0.69, 95% CI: 0.60–0.81, P<0.00001), and 5 (OR =0.66, 95% CI: 0.56–0.76, P<0.00001) years compared with those in the non-No. 10 LND group. Discussion Evidence shows that the No. 10 LND with spleen preservation can improve the survival and the DFS rates for patients with gastric cancer and/or Siewert type II/III AEG who underwent the total gastrectomy. High-quality prospective trials are expected.
Laparoscopic pancreatic surgery is one of the most sophisticated and advanced applications of laparoscopy in the current surgical practice. The adoption of laparoscopic pancreaticoduodenectomy (LPD) has been relatively slow due to the technical challenges. The aim of this study is to review and characterize our successful LPD experiences in patients with distal bile duct carcinoma, periampullary adenocarcinoma, pancreas head cancer, and duodenal cancer and evaluate the clinical outcomes of LPD for its potential in oncologic surgery applications.We retrospectively analyzed the clinical data from 14 patients who underwent LPD from August 2013 to February 2015 in our institute.We presented our LPD experience with no cases converted to open surgery in all 14 cases, which included 10 cases of laparoscopic digestive tract reconstruction and 4 cases of open digestive tract reconstructions. There were no deaths during the perioperative period and no case of gastric emptying disorder or postoperative bleeding. The other clinical indexes were comparable to or better than open surgery.Based on our experience, LPD could be potentially safe and feasible for the treatment of early pancreas head cancer, distal bile duct carcinoma, periampullary adenocarcinoma, and duodenal cancer. The master of LPD procedure requires technical expertise but it can be accomplished with a short learning curve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
