Technique for tailoring complex demarcation in lung segmentectomy.

ABSTRACT: Segmentectomy is a widely adopted surgical procedure, however, experiences of tailoring the intersegmental border have rarely been reported. This paper investigates the strategy and results of tailoring complex demarcation during lung segmentectomy surgery. Because intersegmental demarcation can be divided into plane or curved types according to the location and stereo shape of a segment, a one-size-fits-all method for tailoring the intersegmental demarcation is obviously unreasonable. For tailoring a complex segmentectomy with two or more curved borders, tips including good exposure of the intersegmental demarcation, sharp-blunt combined dissection skill, "work-plane" extension, and "gate" opening techniques all contribute to an accurate segmentectomy. This technique, based on anatomical characteristics, can provide a cutting surface with a greater physiological shape and less curling of the edge, and should be recommended as a general standard method for tailoring complex demarcation.

Project description:BackgroundRobotic anatomic segmentectomy (RATS) for early-stage lung cancer is being increasingly performed in spite of limited published evidence. To evaluate its safety and oncologic efficacy, we compared the outcomes of both RATS and video-assisted thoracoscopic (VATS) segmentectomy in patients with small-sized (<2 cm) peripheral stage IA lung cancer.MethodsFrom November 2011 to January 2018, a total of 130 patients with resected stage IA non-small cell lung cancer (NSCLC) who underwent RATS (n=50) and VATS (n=80) pulmonary segmentectomy were included. Clinicopathologic data, recurrence rate, and survival were recorded.ResultsThe demographics, pulmonary function, comorbidity, and tumor size were similar between RATS segmentectomy and VATS segmentectomy. The surgery time, intensive care unit stay, hospital stay, and blood loss were reduced in the RATS group compared to the VATS group. The number of totally dissected lymph nodes and postoperative complications were similar between the 2 groups. There was no operative mortality. The intensity of narcotic use during hospital stay and the time to return to routine daily activities were also reduced in the RATS group. There was no recurrence observed in the RATS group during the median 38-month follow-up period; meanwhile, during a median 85-month follow-up period in the VATS group, local recurrence and distant recurrence was observed in 2 patients (2.5%) and 3 patients (3.75%) respectively. There was no significant difference in the 5-year recurrence-free survival between the RATS and VATS groups (100% vs. 93.75%; P>0.05).ConclusionsRATS can be performed safely and effectively in patients with early-stage NSCLC. The reduced narcotic use and earlier return to routine daily activities of RATS patients might reflect its less traumatic nature as compared to VATS. For stage IA disease with small tumors (<2 cm), segmentectomy performed by RATS has better oncologic efficacy when compared to VATS, although in this study, this difference did not reach statistical difference.
