The bilateral axillo-breast approach (BABA) for robot-assisted thyroidectomy has some advantages over other minimally invasive thyroidectomies. However, some people do not consider this as a minimally invasive thyroidectomy because of the wider surgical skin flap. Thus, we devised mini-flap BABA robot-assisted thyroidectomy and analyzed the postoperative outcomes. The clinical records of 44 patients undergoing BABA robot-assisted thyroidectomy using a conventional flap or mini-flap were evaluated retrospectively. There were no significant group differences in clinicopathological characteristics. The operating and flap making times were shorter in the mini-flap group (206.18 ± 31.09 vs. 178.90 ± 34.43 min, p = 0.009; 38.85 ± 2.73 vs. 32.21 ± 8.62 min, p = 0.003, respectively). The total drainage amount was smaller in the mini-flap group (196.57 ± 81.40 vs. 150.74 ± 40.80 mL, p = 0.027). The numeric rating scale score and number of analgesics were lower at 2 h postoperatively in the mini-flap group (5.52 ± 0.87 vs. 4.57 ± 1.31, p = 0.006; 0.95 ± 0.22 vs. 0.65 ± 0.49, p = 0.012, respectively). There was no significant group difference in immediate oncological outcomes (p = 1.000). Mini-flap BABA robot-assisted thyroidectomy minimized the surgical flap and improved surgical outcomes. Therefore, it is a form of minimally invasive thyroidectomy. However, long-term follow-up of oncological outcomes is needed.
Purpose: As the Korean population ages, an increasing number of elderly patients with gastric cancer are undergoing surgical resection. The aim of this study was to analyze the surgical outcomes and prognostic factors after gastric cancer surgery for patients 80 years of age or older. Methods: We analyzed the medical records of 720 patients with gastric cancer who underwent gastrectomy from March 2010 to December 2014 retrospectively. Patients were divided into two groups: octogenarians (age ≥80 years, n=46) and non-octogenarians (age <80 years, n=674). We evaluated clinicopathologic data including postoperative morbidity, mortality, and 5-year survival rate. Results: The rate of curative resection was not different between the two groups. The American Society of Anesthesiology score was significantly higher in the octogenarians (P<0.05). Octogenarians exhibited poorer performance scale scores, higher comorbidities, and more advanced TNM stages than non-octogenarians. There was no difference in surgical resection margins between the two groups. In addition, octogenarians suffered from more postoperative morbidity and mortality than non-octogenarians. In the analysis of risk factors of survival after gastrectomy for octogenarians, advanced TNM stage and dose of transfusion were independent risk factors. Overall survival was significantly lower in octogenarians than non-octogenarians. There was no difference in the disease-specific survival for each stage of cancer after adjustment for tumor stage. Conclusion: Octogenarians had more preoperative risk factors and postoperative morbidity and mortality, but cancer-specific survival was comparable with non-octogenarians. Careful preoperative evaluation, thorough resection, and attentive postoperative care can improve the overall survival of octogenarians with gastric cancer.
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.
