Abstract

BackgroundSubxiphoid thoracoscopic thymectomy has been increasingly performed in recent years. This study aimed to assess the differences in outcomes between subxiphoid thoracoscopic thymectomy with and without chest tube drainage.MethodsOverall, 205 subxiphoid thoracoscopic thymectomy operations were performed for myasthenia gravis, including 90 cases without and 115 cases with chest tube drainage. The clinical characteristics and perioperative outcomes of the patients were compared.ResultsThe patients included 112 women and 93 men, with a mean age of 41 years. Two patients in the group without and 5 patient in the group with chest tube drainage developed dyspnea. In the group without chest tube, 6 patients had residual pneumothorax or pleural effusion and had a thoracentesis after surgery (6/90). In the group with chest tube, 7 patients developed delayed pleural effusion and had a thoracentesis after chest tube removal (7/115). The patients in the group without chest tube drainage group yielded lower pain scores.ConclusionsThe omission of chest tube drainage may be a feasible and safe choice for patients with myasthenia gravis undergoing subxiphoid thoracoscopic thymectomy, but further prospective studies are required.

Highlights

  • Surgery is one of the most effective treatments for patients with myasthenia gravis (MG) [1]

  • Subxiphoid thoracoscopic thymectomy is less invasive than the lateral approach, so it has been increasingly used in thoracic surgery for cases of MG or anterior mediastinal tumors [2,3,4,5]

  • Patients and methods A retrospective review was conducted on the clinical data of all the patients who underwent subxiphoid thoracoscopic thymectomy for MG at the First Hospital of Shijiazhuang, affiliated with Hebei Medical University, between November 2017 and September 2019

Summary

Introduction

Surgery is one of the most effective treatments for patients with myasthenia gravis (MG) [1]. Subxiphoid thoracoscopic thymectomy is less invasive than the lateral approach, so it has been increasingly used in thoracic surgery for cases of MG or anterior mediastinal tumors [2,3,4,5]. Chest tubes have been habitually placed in patients after thoracic surgery to evacuate fluids and air. Postoperative chest tube placement may increase the risk of infectious complications such as pneumonia or empyema, worsen the ventilation capacity, aggravate postoperative pain, and prolong hospitalization [6,7,8]. A few studies investigated cases of omission of chest. Subxiphoid thoracoscopic thymectomy has been increasingly performed in recent years. This study aimed to assess the differences in outcomes between subxiphoid thoracoscopic thymectomy with and without chest tube drainage
