[The value of intravesical electrostimulation in the treatment of acute prolonged bladder overdistension]. / Der Stellenwert der intravesikalen Elektrostimulation in der Therapie der akuten prolongierten Blasenüberdehnung.

BACKGROUND: The effectiveness of intravesical electrostimulation (IVES) in the treatment of acute prolonged bladder overdistension (PBO) was investigated. METHODS: Sixteen patients (female 11, male 5, ø 54 years) after PBO (bladder filling volume: 1317+/-320 ml) were evaluated: 11 after surgery and 5 after polytrauma, psychosomatic disorder or LV4 fracture. After exclusion of a neurogenic aetiology and a urodynamic examination, IVES was performed besides IC or suprapubic catheter. RESULTS: Group 1: six patients with a weak detrusor (p(detr. max.)<30 cmH(2)O); group 2: ten patients had detrusor acontractility. After 25 IVES sessions, group 1 showed a significant increase of p(detr. max.) (p=0.01) as well as a decrease in PVR (31% to 3% of bladder capacity, p=0.02). Group 2 had no significant increase of p(detr. max). CONCLUSIONS: Two-thirds of patients with a weak detrusor after PBO will regain balanced voiding after IVES due to detrusor reinforcement. With an acontractile detrusor only bladder sensation improves.

Lung transplantation following lung volume reduction surgery.

OBJECTIVE: Lung volume reduction surgery (LVRS) has been proposed as a possible alternative treatment to lung transplantation (LTX) for selected patients with end-stage emphysema. But whether LVRS is a temporary or permanent alternative to LTX is still under investigation. The aim of this study was to analyze the course of patients undergoing LVRS followed by subsequent LTX. METHODS: Fifteen patients (10 male, 5 female, mean age 53.3 +/- 1.7 years) out of 102 patients, who underwent LVRS between September 1994 and August 1998, underwent LTX 19.6 +/- 3.1 months after LVRS (range 1.7 to 37.6 months) between June 1996 and October 1998. In 9 patients bilateral LVRS was performed, in 6 patients unilateral LVRS. Subsequent LTX was performed bilaterally in 10 patients and unilaterally in 5 patients (1 of these on the contralateral side) to the previous LVRS. The course of lung function and clinical outcome were analyzed in these 15 patients. RESULTS: Mean forced expiratory volume in 1 second (FEV(1)) in the 15 patients prior to LVRS was 18.3 +/- 1.2% of predicted (%p) and increased to 27.0 +/- 2.9 %p (best value within the first 6 months postLVRS) (p = 0.043). In 8 of these patients (non-responders) (53%) LVRS failed to improve FEV(1), whereas in the other 7 patients (responders) (47%) a significant improvement was detected (FEV(1) 18.1 +/- 1.8 %p and 31.9 +/- 3.7 %p, pre- and post-LVRS, respectively, p = 0.003), but declined after 6 to 36 months. At the time of listing for LTX the mean FEV(1) was 18.0 +/- 1.9 %p (no difference between the 2 groups). LTX was performed 15.5 +/- 3.6 months (non-responders) and 25.7 +/- 4.6 months (responders) after LVRS. FEV(1) improved to 81.0 +/- 5.6 %p after LTX (p < 0.001 compared to pre-LTX). The mortality after LVRS was 0%. The 3-month mortality after LTX was 20% (1 patient with primary organ failure, 1 patient with ongoing rejection, 1 patient with sepsis). All 3 patients belonged to the group of nonresponders. Two patients died 5. 5 and 8.5 months after LTX (13.3%) due to fungal infection (Aspergillus spp.) and MRSA sepsis, respectively (1 non-responder, 1 responder). CONCLUSIONS: Successful LVRS delays the need for LTX and offers better conditions for LTX. However, patients without functional improvement after LVRS have a high perioperative risk at subsequent LTX.

Video assistance reduces complication rate of thoracoscopic sympathicotomy for hyperhidrosis.

BACKGROUND: Thoracoscopic sympathicotomy has proved successful in the treatment of palmar hyperhidrosis. However, up to 8% of patients experience Horner's syndrome, and about 50% show compensatory sweating. This study evaluates the role of video assistance in thoracoscopic sympathicotomy for primary hyperhidrosis of the upper limb. METHODS: Six hundred fifty-six thoracoscopic sympathicotomies were performed from below T1 to T4 in 369 patients. Of the operations, 558 were done under direct view (CTS group) and 98, with video assistance (VATS group). Follow-up was complete for 78.3% of patients after a median observation period of 16 years. RESULTS: Dry limbs were immediately achieved in 93% of the CTS group and 98% VATS group (p = 0.98). In the CTS group, Horner's syndrome occurred after 2.2% of all operations and rhinitis in 8.3%. No patient in the VATS group showed any symptom of Homer's triad (p = 0.03 versus CTS group) or rhinitis (p = 0.02 versus CTS group). Compensatory sweating was observed in 66.8% in the CTS group versus 69% in the VATS group (p = 0.73) and gustatory sweating, in 50.4% versus 27.6%, respectively (p = 0.01). CONCLUSIONS: In performing thoracoscopic sympathicotomy for excessive upper-limb hyperhidrosis, we observed a significant decrease in the incidence of Horner's syndrome, rhinitis, and gustatory sweating when the procedure was guided by video imaging.

Long-term results of 630 thoracoscopic sympathicotomies for primary hyperhidrosis: the Vienna experience.

OBJECTIVE: To evaluate of the results of thoracoscopic sympathicotomy for upper limb hyperhidrosis with a median observation period of more than 15 years. DESIGN: Retrospective clinical observation study. SETTING: University-affiliated tertiary referral centre. SUBJECTS: 630 consecutive operations in 352 patients (median age 30.1 yrs) for primary palmar (68%), axillary (12.7%) and combined hyperhidrosis (19.3%). INTERVENTIONS: Thoracoscopic sympathicotomy from below T1 to T4 including the fibres of Kuntz using electrocautery through single site access. MAIN OUTCOME MEASURES: Perioperative success and complication rates (all patients); long-term follow-up by a questionnaire and/or clinical examination (83.3% of patients) after a median period of 16 yrs. Calculation of statistical significance of differences between groups with c2-test. RESULTS: 67.8% of patients were fully satisfied, 25.7% were partially satisfied and would again agree to the operation. In 93% the procedure cured hyperhidrosis permanently. Compensatory and gustatory sweating was observed in 67% and 47% of cases, respectively. Overall success was significantly (p < 0.001) lower in the group with axillary hyperhidrosis. Main complications: drainage for pneumothorax 1.3%, Horner's syndrome in 3.8%, subcutaneous emphysema 2.1%. CONCLUSION: Thoracoscopic sympathicotomy proved to be highly effective even after long-term follow-up. Compensatory sweating impairs patients' satisfaction in some cases.
