Evaluation of Early Results Video-Assisted Thoracoscopic Surgery with Multi-Joint Wristed Instruments in Lung Cancer Surgery.

Background: Our objective in this study is to compare the early outcomes of patients who underwent technical resection of non-small cell lung cancer (NSCLC) with video-assisted thoracoscopic surgery (VATS) with multi-joint wristed instruments, also known as surgeon-powered robotic surgery (SpRS) and conventional VATS. Methods: One hundred twenty-two thoracoscopic lung resections were performed in our hospital for NSCLC between March 2021 and March 2022. Of these resections, 95 were performed with VATS, while 27 patients underwent the SpRS technique. Results: Lobectomy was performed in 112 patients (91.8%), and segmentectomy was performed in 10 patients (8.2%). The median duration of hospitalization was 5 days in patients who underwent VATS, while the median duration of hospitalization was 4 days in patients who underwent the SpRS technique. No significant difference was found between the groups when demographic characteristics were compared with surgical techniques. The median drainage was 125 mL in the SpRS technique, while 150 mL of drainage occurred in patients who underwent resection by VATS (0.165). While an average of 12 lymph nodes was dissected in the VATS group, an average of 14 lymph nodes was dissected in the SpRS group (0.602). Complications occurred in 17 patients (13.9%). Complications were observed at a rate of 16.8% in the VATS group, while complications were observed at a rate of 3.7% in the SpRS group (P = .116). Conclusion: As a result, our study shows that it is an effective and reliable method with early results similar to thoracoscopic surgery. Registration Number: 2022-194.

Survival impact of unexpected N2 in stage IIIB/N2 non-small cell lung cancer patients.

BACKGROUND: We investigated the effect of unexpected N2 on survival in stage IIIB/N2 cases. METHODS: We retrospectively analyzed 1803 non-small cell lung cancer patients between 2010 and 2016. There were 89 patients (4.9%) with unexpected N2 (pathological (p) IIIB/N2 group), whereas 49 patients (2.7%) with cN2 (clinical (c) IIIB/N2 group). Although pIIIB/N2 group underwent surgery followed by adjuvant therapy, the cIIIB/N2 group of patients had multimodality treatment including induction chemotherapy ± radiotherapy followed by surgery. RESULTS: The five-year overall survival (OS) for all patients was 36.0% [median survival time (MST) 27.9 months], and disease-free survival (DFS) was 28.9% (MST, 18.2 months). The OS was 39.6% (MST: 34.4 months) and the median DFS time was 31.1% (Median: 23.1 months) in the pIIIB/N2 group, whereas it was 29.2% (MST: 23.0 months) for OS and 22% (median: 12.4 months) for DFS in the cIIIB/N2 group. There were no significant OS and DFS differences between the pIIIB/N2 group and the cIIIB/N2 group (p = 0.124 and p = 0.168, respectively). CONCLUSIONS: In stage IIIB/N2 cases, the fact that N2 could not be detected preoperatively with minimally invasive or invasive methods and was detected in the pathological examination after surgery does not provide a survival advantage.

Comparison of short-term results of subxiphoid and conventional video-assisted thoracoscopic surgery in diagnostic wedge resections.

BACKGROUND: This study aimed to compare early results in patients who underwent subxiphoid wedge resection with those operated on using a multiportal approach. METHODS: We retrospectively evaluated 151 patients who underwent diagnostic wedge resection for suspected interstitial lung disease. Patients who underwent wedge resection via subxiphoid video-assisted thoracoscopic surgery and conventional video-assisted thoracoscopic surgery were compared. RESULTS: The study included 90 men (59.6%) and 61 women (40.4%) with a mean age of 54.8 ± 12 years. Of these, 127 patients underwent conventional video-assisted thoracoscopic surgery and 24 patients underwent subxiphoid video-assisted thoracoscopic surgery. Postoperative complications occurred in 13 patients (8.6%), with no significant difference according to surgical technique. Sex was a significant factor in the rate of complications (12.2% in men vs. 3.2% in women). There was no intraoperative mortality; the 30-day mortality rate was 4% (n = 6). Five nonsurviving patients were in the conventional video-assisted thoracoscopic surgery group and 1 was in the subxiphoid video-assisted thoracoscopic surgery group (p = 0.95). CONCLUSION: The results of this study indicate that the subxiphoid approach reduced procedure time and length of hospital stay in the early period, while there was no significant difference between the techniques in terms of complications or mortality. Based on these findings, we conclude that surgical outcomes were as successful with the subxiphoid approach as with conventional video-assisted thoracoscopic surgery.
