Robotic thymectomy has been adopted recently and has been shown to be safe and feasible in treating thymic tumors and myasthenia gravis. The surgical indications of robotic technology are expanding, with advantages including an excellent surgical view and sophisticated manipulation. Herein, we describe technical aspects, considerations, and outcomes of robotic thymectomy.

Background: The objective of this study was to demonstrate the safety, efficacy, and feasibility of intraoperative monitoring of the recurrent laryngeal nerves during thoracoscopic and robotic 3-field esophagectomy. Methods: This retrospective analysis details our initial experience using intraoperative nerve monitoring (IONM) during minimally invasive 3-field esophagectomy. Data were obtained from a prospectively maintained database and electronic medical records. The study included all patients who underwent minimally invasive (video-assisted thoracic surgery/robotic) transthoracic esophagectomy with neck anastomosis. The patients were divided into those who underwent IONM during the study period and a historical cohort who underwent 3-field esophagectomy without IONM at the same institution. Appropriate statistical tests were used to compare the 2 groups. Results: Twenty-four patients underwent nerve monitoring during minimally invasive 3-field esophagectomy. Of these, 15 patients underwent thoraco-laparoscopic operation, while 9 received a robot-assisted procedure. In the immediate postoperative period, 8 of 24 patients (33.3%) experienced vocal cord paralysis. Relative to a historical cohort from the same institution, who were treated with surgery without nerve monitoring in the preceding 5 years, a 26% reduction was observed in the nerve paralysis rate (p=0.08). On follow-up, 6 of the 8 patients with vocal cord paralysis reported a return to normal vocal function. Additionally, patients who underwent IONM exhibited a higher nodal yield and a decreased frequency of tracheostomy and bronchoscopy. Conclusion: The use of IONM during minimally invasive 3-field esophagectomy is safe and feasible. This technique has the potential to decrease the incidence of recurrent nerve palsy and increase nodal yield.

A 43-year-old man with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) was admitted to our hospital with aggravated exertional dyspnea and successfully treated with robotic transmitral septal myectomy. Minimally invasive transmitral septal myectomy may be a feasible surgical option for the treatment of HOCM in selected cases as an alternative to transaortic myectomy.

본 연구는 로봇을 이용한 최소침습절개술 접근과 기존의 정중흉골절개술 접근을 이용한 심장판막수술환자를 대상으로 통증, 수면, 자가간호수행을 파악하고 이를 비교분석하기 위한 조사연구이다. 대상자는 서울시 일개 상급종합병원에서 심장수술을 시행한 대상자 중 정중흉골절개술군 64명, 최소침습절개술군 64명을 대상으로 하였다. 자료분석은 SPSS 22.0 프로그램을 이용하여 기술적 통계, ${\chi}^2$ 검증, paired t-test를 시행하였다. 수술 후 2일째, 5일째 모두 통증은 로봇을 이용한 최소침습절개술군이 정중흉골절개술군에 비해 높았다. 통증발생부위는 두 군 모두 수술접근부위로 크게 나타났다. 수면은 수술 후 2일째 정중흉골절개술군에서 높게 나타났으며, 자가간호수행은 최소침습절개술군에서 높게 나타났다. 그러므로 로봇 수술의 재원기간 단축과 빠른 회복 등의 장점에도 불구하고 대상자의 통증관리를 위해 정확한 통증 사정 및 차별화된 프로토콜의 적용이 필요시 된다. 또한 성별, 연령 및 수술방법의 차이를 고려하여 안위를 증진시키기 위한 체계화된 교육 프로그램 중재가 요구되어진다.

Minimally invasive esophagectomy (MIE) was first introduced in the 1990s. Currently, it is a widely accepted surgical approach for the treatment of esophageal cancer, as it is an oncologically sound procedure; its advantages when compared to open procedures, including reduction in postoperative complications, reduction in the length of hospital stay, and improvement in quality of life, are well documented. However, debates are still ongoing about the safety and efficacy of MIE. The present review focuses on some of the current issues related to conventional MIE and robot-assisted MIE based on evidence from the current literature.

Purpose: To compare perioperative outcomes and oncologic outcomes in endometrial cancer patients treated with laparotomy, and laparoscopic or robotic surgery. Materials and Methods: Endometrial cancer patients who underwent primary surgery from January 2011 to December 2014 were retrospectively reviewed. Perioperative outcomes, including estimated blood loss (EBL), operation time, number of lymph nodes retrieved, and intra and postoperative complications, were reviewed. Recovery time, disease free survival (DFS) and overall survival (OS) were compared. Results: Of the total of 218 patients, 143 underwent laparotomy, 47 laparoscopy, and 28 robotic surgery. The laparotomy group had the highest EBL (300, 200, 200 ml, p<0.05) while the robotic group had the longest operative time (302 min) as compared with laparoscopy (180 min) and laparotomy (125 min) (p<0.05). Intra and postoperative complications were not different with any of the surgical approaches. No significant difference in number of lymph nodes retrieved was identified. The longest hospital stay was reported in the laparotomy group (four days) but there was no difference between the laparoscopy (three days) and robotic (three days) groups. Recovery was significantly faster in robotic group than laparotomy group (14 and 28 days, p =0.003). No significant difference in DFS and OS at 21 months of median follow up time was observed among the three groups. Conclusions: Minimally invasive surgery has more favorable outcomes, including lower blood loss, shorter hospital stay, and faster recovery time than laparotomy. It also has equivalent perioperative complications and short term oncologic outcomes. MIS is feasible as an alternative option to surgery of endometrial cancer.

Recently, an increasing interest in less invasive surgery has led to the advent of laparoendoscopic single-site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES). LESS and NOTES could be technically challenging, but available literature has demonstrated the feasibility and safety of LESS for benign gynecologic diseases. However, the evidence is not strong enough to recommend the use of LESS over that of conventional multiport laparoscopic surgery (MLS). As per the results of the most recently published meta-analysis, the majority of surgical outcomes are equivalent between LESS and MLS, except for the longer operative time in LESS for both adnexal surgery and hysterectomy. Although an increasing number of studies have reported on robotic LESS, NOTES, and LESS for gynecologic malignancy, definite conclusions have not been drawn owing to the lack of sufficient information.

Purpose: Minimally invasive gastrectomy is a promising surgical method with well-known benefits, including reduced postoperative complications. However, for total gastrectomy of gastric cancers, this approach does not significantly reduce the risk of complications. Therefore, we aimed to evaluate the incidence and risk factors for the severity of complications associated with minimally invasive total gastrectomy for gastric cancer. Materials and Methods: The study included 392 consecutive patients with gastric cancer who underwent either laparoscopic or robotic total gastrectomy between 2011 and 2019. Clinicopathological and operative characteristics were assessed to determine the features related to postoperative complications after minimally invasive total gastrectomy. Binomial and multinomial logistic regression models were used to identify the risk factors for overall complications and mild and severe complications, respectively. Results: Of 103 (26.3%) patients experiencing complications, 66 (16.8%) and 37 (9.4%) developed mild and severe complications, respectively. On multivariate multinomial regression analysis, independent predictors of severe complications included obesity (OR, 2.56; 95% CI, 1.02-6.43; P=0.046), advanced stage (OR, 2.90; 95% CI, 1.13-7.43; P=0.026), and more intraoperative bleeding (OR, 1.04; 95% CI, 1.02-1.06; P=0.001). Operation time was the only independent risk factor for mild complications (OR, 1.06; 95% CI, 1.001-1.13; P=0.047). Conclusions: The risk factors for mild and severe complications were associated with surgery, indicating surgical difficulty. Surgeons should be aware of these potential risks that are related to the severity of complications so as to reduce surgery-related complications after minimally invasive total gastrectomy for gastric cancer.
