Comparison of short-term outcomes of video-assisted thoracoscopic (VATS) plication of diaphragmatic eventration - a six-year prospective cohort study.

Abstract

Diaphragmatic eventration is one of the rarest conditions characterized by elevation of the hemidiaphragm while maintaining its normal attachments. In recent years, video-assisted thoracoscopic surgery (VATS) has gained popularity for diaphragmatic surgery. In this study, we share our experience over six years with VATS plication of diaphragmatic eventration. We conducted a prospective study at our institute for six years from April 2016 to March 2021, which included 37 symptomatic patients with diaphragmatic eventration. The sample size reported in this study is one of the largest to date for VATS diaphragmatic plication. Of these, 18 patients underwent combined stapler and suture plication, and 19 patients underwent single modality approach (10-stapled resection, 9-suture alone plication). All patients were followed-up for a minimum of 2years. Comparative analysis of the combined approach and the single modality approach was performed. The mean operative time was significantly longer with the combined approach (p value < 0.01). However, there was no difference in postoperative pain (p value = 0.50), analgesia requirement (p value = 0.72), or pleural drainage (p value = 0.32) between the two approaches. Although not statistically significant, the combined approach had fewer post-operative complications (p value = 0.32). Besides, the Single modality approach resulted in one recurrence (p value = 0.32) and one mortality (p value = 0.32). VATS diaphragmatic plication using staplers and/or sutures is safe and efficacious in the management of diaphragmatic eventration. Surgeons should consider using both staplers and sutures whenever possible, rather than selecting one over the other.
