Winged scapula following axillary thoracotomy with long thoracic nerve preservation

The Incidence of Winged Scapula after Thoracic Cancer Surgery: A Prospective Cohort Study

BACKGROUND

 Lung cancer is the leading cause of cancer-related deaths, and surgery is still the first treatment of choice in early and locally advanced cases. One of the iatrogenic complications is the serratus anterior palsy, which could lead to a winged scapula (WS). Unfortunately, the incidence of this deficit in thoracic surgery is unclear. Our primary aim was to determine the incidence of WS in lung cancer patients in a single-center experience.

METHODS

 We conducted a retrospective analysis of prospectively collected data with patients eligible for oncological thoracic surgery from March 2013 until January 2014. A physical evaluation of the WS was performed pre- and postoperatively, at the discharge and after 1 year of follow-up.

RESULTS

 A total of 485 patients were evaluated; 135 (27.8%) showed WS. Longer operative time (p < 0.0001), type of surgery (p < 0.0001), lymphadenectomy (p < 0.0001), and neoadjuvant treatment prior surgery (p = 0.0005) were significantly related to the WS injury. Multivariable analysis showed that type of surgery was significantly associated with WS (p < 0.0001). After 1 year, 41.6% still had WS.

CONCLUSION

 The incidence of WS was similar to the literature. As WS incidence is underdiagnosed, assessment and correct education about possible deficits or impairments should be improved. Moreover, when a minimally invasive approach is not planned, it is a good clinical practice to discuss surgical strategies with surgeons to reduce this deficit.

Recovery of brachial plexus injury after bronchopleural fistula closure surgery based on electrodiagnostic study: A case report and review of literature

BACKGROUND

Axillary thoracotomy and muscle flap are muscle- and nerve-sparing methods among the surgical approaches to bronchopleural fistula (BPF). However, in patients who are vulnerable to a nerve compression injury, nerve injury may occur. In this report, we present a unique case in which the brachial plexus (division level), suprascapular, and long thoracic nerve injury occurred after BPF closure surgery in a patient with ankylosing spondylitis and concomitant multiple joint contractures.

CASE SUMMARY

A 52-year-old man with a history of ankylosing spondylitis with shoulder joint contractures presented with right arm weakness and sensory impairment immediately after axillary thoracotomy and latissimus dorsi muscle flap surgery for BPF closure. During the surgery, the patient was positioned in a lateral decubitus position with the right arm hyper-abducted for approximately 6 h. Magnetic resonance imaging and ultrasound revealed subclavius muscle injury or myositis with brachial plexus (BP) compression and related neuropathy. An electrodiagnostic study confirmed the presence of BP injury involving the whole-division level, long thoracic, and suprascapular nerve injuries. He was treated with medication, physical therapy, and ultrasound-guided injections. Ultrasound-guided steroid injection at the BP, hydrodissection with 5% dextrose water at the BP and suprascapular nerve, and intra-articular steroid and hyaluronidase injection at the glenohumeral joint were performed. On postoperative day 194, the pain and arm weakness were resolved, and a follow-up electrodiagnostic study showed marked improvement.

CONCLUSION

Clinicians should consider the possibilities of multiple nerve injuries in patients with joint contracture, and treat each specific therapeutic target.
