A prospective comparative study of thoracoscopic transareolar and uniportal approaches for young male patients with primary spontaneous pneumothorax

Periareolar approach in video-assisted thoracoscopic surgery for right middle lobectomy: a novel technique

BACKGROUND

Uniportal thoracoscopic right middle lobectomy (RML) poses greater technical challenges than other lobectomies. Although two-port thoracoscopy offers convenience, it results in heightened surgical trauma and scarring. The periareolar incision is rarely used in lobectomy while known for its cosmetic advantages. This study presents the periareolar access (combining a periareolar port and a 1-cm port) for video-assisted thoracoscopic surgery (VATS) in RML, comparing it with the traditional uniportal technique in both male and female patients.

METHODS

Eighty patients who underwent RML were randomly divided into two groups: the periareolar VATS (PV) approach (n = 40) and the uniportal VATS (UV) approach (n = 40) from August 2020 to February 2023. All patients were followed up for 1 year and clinical data were collected and analyzed.

RESULTS

No significant differences in complications, blood loss, duration of chest tube placement, and length of postoperative hospital stay were observed between two methods. However, the PV group exhibited significantly shorter operative time, reduced postoperative visible scarring and lower visual analogue scores (VAS) for postoperative pain (P < 0.05). Additionally, the PV group demonstrated significantly higher cosmetic and satisfaction scores at the 6-month postoperative assessment (P < 0.05). Notably, breast ultrasound follow-up revealed two cases injuries of the mammary glands in female patients, and sensory function of most nipple and areola remained intact except two cases in all PV group patients.

CONCLUSIONS

Periareolar VATS emerges as a promising alternative approach for RML, providing clear benefits in pain management and cosmetic outcomes, while maintaining safety and convenience.

Transareolar Video-Assisted Thoracoscopic Surgery in Females: A Novel Incision for Pulmonary Ground Glass Nodule Resection

Purpose: Uniportal video-assisted thoracoscopic surgery (VATS) is recognized for its minimally invasive nature, widely adopted globally. However, the evident scarring it leaves often triggers psychological apprehension and resistance to surgery. Transareolar incision, known for its superior cosmetic outcome with no visible scars, poses challenges in women due to the risk of mammary gland damage. In this report, we present successful pulmonary ground glass nodule (GGN) resection using transareolar VATS in female patients, aiming to address these concerns. Materials and Methods: We retrospectively analyzed the clinical data of 35 female patients who underwent GGN resection through transareolar VATS between August 2020 and March 2022. Results: There were no serious complications or perioperative deaths in this cohort of 35 female patients undergoing GGN resection through transareolar VATS. The operations, including local resection or segmentectomy, had an average duration of 70.1 ± 26.4 minutes, with a tube duration of 4.7 ± 2.1 days and a hospitalization time of 7.2 ± 2.3 days. The surgical approach varied, with 21 cases using transareolar uniport, 8 cases assisted by a 3-mm tiny port, and 6 cases converted to two-port VATS. Scar outcomes varied, with 21 cases showing no scar, 8 cases displaying a microscar, and 6 cases presenting a dominant scar of 1.7 ± 0.5 cm. Postoperative pain scores at 1 week and 1 month were 1.9 ± 0.9 and 1.0 ± 0.9, respectively, and the wound numbness occurred in 2.86% (1/35) of cases. Regarding breast complications, 2 patients suffered delayed healing of the incision. No damage and inflammation of glands were detected by breast B-mode ultrasonography. Conclusions: The transareolar incision emerges as a novel approach for VATS in female patients, offering advantages in terms of pain management and cosmetic outcomes.

Feasibility of tubeless thoracoscopic bullectomy in primary spontaneous pneumothorax patients

OBJECTIVES

Although early removal of postoperative chest drains can facilitate postoperative recovery, there are risks of undetected bleeding and a need for re-drainage to treat delayed pulmonary air leaks. In this study, we aimed to prospectively examine the feasibility of tubeless thoracoscopic bullectomy in primary spontaneous pneumothorax (PSP) patients.

METHODS

Between January 2021 and November 2021, 30 PSP patients were enrolled in this prospective study. The absence of air leakage was confirmed and radiographic evidence of lung expansion was acquired; the tube was then removed in the operating room. The primary endpoint was postoperative air leakage requiring re-drainage among patients who underwent tube removal in the operating room. The secondary endpoints were postoperative pain (numerical rating scale) on postoperative days (PODs) 1, 7, and 28, morbidity, and postoperative hospitalization time.

RESULTS

Four (13.3%) patients were excluded because of underlying pulmonary disease (n = 2) and air leaks (n = 2) detected in the operating room. Chest drainage tubes were removed in the operating room for the remaining 26 patients; none of them required re-drainage. The mean postoperative hospitalization time was 1.2 ± 0.4 days. The mean numerical rating scale scores were 4.2 ± 2 (median: 4.5), 1.6 ± 1.6 (median: 1), and 0.4 ± 0.8 (median: 0) on PODs 1, 7, and 28, respectively. Only one case of hemoptysis occurred as a postoperative complication.

CONCLUSIONS

Tubeless thoracoscopic bullectomy for PSP is feasible and may reduce the postoperative hospitalization time; however, it does not significantly reduce pain on POD1.
