Background: Thoracoscopic sympathicotomy is highly effective in treating disabling palmar hyperhidrosis. The ideal level to maximize efficacy and minimize the side effect of compensatory hyperhidrosis (CH) is controversial. This study compared sympathicotomy over the second (R2) vs third (R3) costal head relative to these variables in patients with massive palmar hyperhidrosis. Methods: This prospective, randomized study enrolled 121 patients with disabling palmoplantar hyperhidrosis assigned to bilateral sympathicotomy (sympathetic transection), which was done over R2 in 61 (n = 122 extremities) or R3 in 60 (n = 120 extremities). Patients were questioned at 6 months and at 1 year or more to assess efficacy, side effects, and satisfaction with the procedure. Results: Sympathicotomy at R2 failed to cure palmar hyperhidrosis in 5 of 122 (4.1%) extremities, but only 2 (1.6%) were to a truly profound dripping level of recurrence. Sympathicotomy at R3 failed to cure palmar hyperhidrosis in 5 of 120 extremities (4.2%), and all were dramatic failures with dripping recurrent sweating. The patients whose palmar hyperhidrosis was not completely cured were aged 19.7 ± 2.5 vs 26.4 ± 8.0 years ( p = 0.04). Two R3 patients with failure underwent three redo R2 sympathicotomies, with curative results. R2 patients showed a trend toward a higher level of CH vs R3 patients at 6 months and after 1 year. The CH severity scale was 4.7 ± 2.7 (n = 38) for R2 vs 3.8 ± 2.8 (n = 36) for R3 ( p = NS) at 6 months and 4.7 ± 2.5 (n = 43) for R2 vs 3.7 ± 2.8 (n = 37) for R3 ( p = NS) after 1 year. Younger age, male sex, and higher levels of preoperative and postoperative plantar sweating were predictors of failed sympathicotomy. Increased age was associated with increased CH. Conclusions: R2 and R3 sympathicotomy for massive palmoplantar hyperhidrosis are highly effective, with low recurrence and incidences of severe CH. R2 tends to have a higher level of CH vs R3, and a higher incidence of dramatic failures is suggested in R3 patients, for which reoperation at the R2 level will likely be curative.

Evidence-based medicine suggests that in the management of chronic anal fissure (CAF), lateral internal sphincterotomy (LIS) is far more effective than medical treatment in lowering the anal sphincter tone and curing the fissure. In the current study, we developed a treatment algorithm from topical nitroglycerin (NTG) to botulinum toxin type A (Botox [BTX]) to LIS and analyzed its cost benefit by calculating the effective and potential costs based on the treatment success and the rate of avoided surgeries. Patients presenting between November 2003 and December 2004 with CAF and symptoms for greater than 3 months were prospectively treated according to a treatment algorithm which started with (1) topical NTG, in case of failure (2) injection of BTX, thus limiting (3) surgery to those who failed both nonsurgical options or at any point chose the surgical approach. Based on the primary end points of fissure healing or surgery, we calculated the true cost (algorithm) and the potential incremental cost (BTX plus surgery or surgery in all patients, respectively). Sixty-seven patients with CAF (25 men and 42 women; median duration of symptoms, 16 weeks) were treated according to the algorithm. NTG alone was successful in fissure healing in 31 of 67 patients (46.2%). Two developed a recurrent fissure and then received BTX as part of the protocol. Of the 36 patients who failed NTG trial, 3 requested surgery; the others were treated with BTX, which was successful in 84.8%. Five patients (15.2%) failed BTX and subsequently required surgery. The overall surgery rate in the whole study group was 11.9%, whereas CAF healed in 88.1% of our patients with medical treatment alone. Cost for NTG is $10; for 100 units BTX, $528; and for outpatient surgery, $1119. The total cost for these 67 patients therefore was $33,252 ($290 for NTG, $20,580 for NTG plus BTX, $3,357 for NTG plus LIS, and $9,025 for NTG plus BTX plus LIS). If all patients had received BTX with a 15% failure rate, the total cost would have been $56,688 (70.3% cost increase). If all patients had undergone surgery as initial/only treatment, the total cost would have been $74,973 (125% cost increase). Our treatment algorithm for CAF with stepwise escalation can avoid surgery in 88% of the patients. It is highly cost-efficient and resulted in savings of 41% (compared with BTX plus LIS) and up to 70% (compared with surgery in all patients), respectively. [ABSTRACT FROM AUTHOR]
