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

Abstract

This study aimed to compare early results in patients who underwent subxiphoid wedge resection with those operated on using a multiportal approach. 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. 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). 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.
