Bilateral thoracoscopic sympathectomy for primary hyperhydrosis: a review of 335 cases

The impact of endoscopic thoracic sympathectomy on sudomotor function in patients with palmar hyperhidrosis

Purpose

When performing endoscopic thoracic sympathectomy (ETS) in palmar hyperhidrosis patients, a device can be used to measure sweat volume pre- and postoperatively in order to assess indications and treatment effects. In this study, we measured changes in the dynamics of sweating in hyperhidrosis patients pre- and postoperatively and compared the values with those in healthy subjects without hyperhidrosis.

Methods

The patient group comprised 25 persons with palmar hyperhidrosis who were scheduled for ETS. The dynamics of sweating was measured at 1 day prior to surgery and at 2 days postoperatively, in 18 patients at > 1 year postoperatively in another palmar hyperhidrosis group, and in 20 healthy subjects without hyperhidrosis. A device for measuring local sweat volume was applied at the thenar eminence of both palms. Indicators established were basal sweat rate (BSR; mg/min/cm²), peak sweat rate (PSR; mg/min/cm²) during mental stress (sympathetic sweating response), sweat volume (SV), and sweat time (ST; s).

Results

After surgery, all of the indicators were significantly reduced in hyperhidrosis patients and there was very little response to mental stress. The subgroup of these patients assessed at > 1 year after ETS showed a trend of increased BSR similar to that of healthy subjects. These changes did not correlate with the extent of the removal surgery. Preoperatively, hyperhidrosis patients had significantly greater BSR, PSR, and SV and longer ST than healthy subjects.

Conclusion

All of the sweating parameters were increased in palmar hyperhidrosis patients prior to surgery. Immediately after ETS, all these parameters were significantly reduced. At > 1 year after ETS, the BSR had increased to a level similar to that of the healthy volunteers, although PSR did not respond to mental stress.

The quality of life and satisfaction rate of patients with upper limb hyperhidrosis before and after bilateral endoscopic thoracic sympathectomy

Background:

Hyperhidrosis is a functional disorder identified by excessive sweating. Its incidence is approximately 1% in any population. Bilateral endoscopic thoracic sympathectomy (BETS) intervention is the definitive treatment of choice for palmar and axillary hyperhidrosis.

Aims and Objectives:

The purpose of this study is to evaluate and compare the quality of life (QOL) and satisfaction rate of patients with upper limb hyperhidrosis before and after BETS surgery and the influence of compensatory hyperhidrosis (CH) on patients’ QOL after surgery.

Settings and Design:

This study is a cross-sectional study designed to generate longitudinal data.

Subjects and Methods:

This study is a cross-sectional study designed to generate longitudinal data pre- and postbilateral BETS prospectively. This study was conducted in the surgery department of University Hospital in Riyadh, Saudi Arabia. Hundred patients with upper limb hyperhidrosis who underwent BETS from 2014 to 2017 were included. A modified and validated QOL questionnaire for hyperhidrosis was completed by the patients themselves in order to compare the QOL for patients both before and after BETS. Patients’ satisfaction and the occurrence of CH were obtained postoperatively.

Statistical Analysis Used:

Data were analyzed using the SPSS^® statistical package for social studies, version 22.0 (SPSS 22; IBM Corp., New York, NY, USA) for Windows^®.

Results:

A total of 100 patients completed the questionnaire; 94% of patients had a positive QOL outcome after the surgery. The mean decrease in QOL scores was −42.0 points toward better QOL. The site of sweating had a significant effect on the patients’ QOL before and after the surgery (P value < 0.001). Moreover, 76% of patients reported a high satisfaction rate.

Conclusion:

Primary hyperhidrosis can negatively impair patients’ QOL in different domains. BETS showed to be an effective option for improving the QOL of patients and it provided both short- and long-term effectiveness in treating upper limb hyperhidrosis. CH did not interfere with the rate of patient satisfaction or their QOL postoperatively.

Granular cell tumor of the stellate ganglion presenting with Horner's syndrome

We report a granular cell tumor (GCT) that occurred within the stellate ganglion of a 26-year-old woman who initially presented with a unilateral Horner's syndrome and progressive right upper extremity pain. We also review the literature related to the differential diagnoses of such a cervicothoracic tumor, with particular emphasis on the embryologic origin of these possibilities. GCT are rare tumors of Schwann cell origin which are more often found in subcutaneous locations than in relation to neural elements. In this woman, a mass identified on preoperative imaging was positioned anterolateral to the T1 vertebral body and displaced the vertebral artery anteriorly. During surgery, the lesion was observed within the sympathetic chain in the area of the stellate ganglion. The sympathetic chain was transected above and below the mass in order to achieve an adequate resection. The pathology demonstrated polygonal cells with diffuse eosinophilic granular cytoplasm positive for CD68 (a marker of lysosomes) and S-100 (a marker of neural crest derivatives) which established the diagnosis of GCT. This is the first patient, to our knowledge, with a granular cell tumor arising from the stellate ganglion.

Video-assisted thoracic surgery complications

Video-assisted thoracic surgery (VATS) is a miniinvasive technique commonly applied worldwide. Indications for VATS are very broad and include the diagnosis of mediastinal, lung and pleural diseases, as well as large resection procedures such as pneumonectomy. The most frequent complication is prolonged postoperative air leak. The other significant complications are bleeding, infections, postoperative pain and recurrence at the port site. Different complications of VATS procedures can occur with variable frequency in various diseases. Despite the large number of their types, such complications are rare and can be avoided through the proper selection of patients and an appropriate surgical technique.
