In a randomized, double-blind, placebo-controlled trial, we evaluated the use of preoperative local anesthesia with regard to postoperative pain. Before surgery in 66 patients scheduled for cholecystectomy, the abdominal wall along the proposed line of incision was infiltrated with 70 mL of 0.25% ropivacaine, 70 mL of 0.125% ropivacaine, or 70 mL of saline. Wound pain at rest, wound pain during mobilization, and pressure exerted to reach maximum pain tolerance were assessed after 6, 26, 50, and 74 h and after 7 days. Consumption of analgesics was recorded. At the 6-h assessment, there was a statistically significant dose-related decrease in wound pain during mobilization (P = 0.001) and an increase of pressure exerted to reach maximum pain tolerance (P < 0.001). The tests were two-tailed and performed at a significance level of P < 0.05. There were no significant differences between the groups at later pain control assessments. The median time to first request for postoperative analgesics was significantly shorter (P = 0.014) in the saline group than in the ropivacaine 0.25% group. These effects are suggested to be a residual anesthetic effect of ropivacaine. The study gives no support to the hypothesis that preoperative local anesthetics dampen the inflammatory response and ensuing hyperalgesia.

Facial blushing is one of the cardinal symptoms of social phobia and has a strong negative impact on the quality of life. Traditional therapeutic options are psychotherapy and pharmacological treatment. The results of these treatments on facial blushing are poorly documented. To investigate whether endoscopic bilateral transection of the upper thoracic sympathetic chain is efficient in the treatment of facial blushing, 244 consecutive patients were treated with bilateral endoscopic transthoracic sympathicotomy (ETS). The results were evaluated by questionnaire and symptoms assessed with visual analogue scales (0-10). There was no mortality nor conversion to open surgery. No Horner's syndrome occurred. Two patients with postoperative pneumothorax were treated with intercostal drainage and one small pulmonary embolus was detected. The questionnaire was answered by 219 patients (90%) a mean (+/- SEM) of 8 months (+/- 9 days) after surgery. Facial blushing (mean +/- SEM) was reduced from 8.7 +/- 0.1 to 2.2 +/- 0.2, P < 0.0001, by the operation. Heart palpitations in stressful situations were also reduced (3.7 +/- 0.3 to 1.3 +/- 0.1, P < 0.0001). The quality of life was substantially improved. The main side-effect was redistribution of sweating from the upper to the lower part of the body. Increased sweating of the trunk occurred in 75% of the patients. Overall, 85% of the patients were satisfied with the result and 15% were to some degree dissatisfied, mainly due to insufficient effect, but only four patients (2%) regretted the operation. As this is an open study, the results must be viewed with caution. ETS, however, appears to be an efficient, safe and minimally invasive surgical method for the treatment of facial blushing.

The accuracy with which pheochromocytomas and paragangliomas can be visualized questions nowadays the routine use of abdominal approach. In selected cases of sporadic unilateral chromaffin tumours, a posterior, lateral, or even laparoscopic approach should be considered.

Over a 21 year period there seems to have been a decrease in the frequency of secondary aortoenteric fistulas after aneurysm surgery, a longer interval before they occur, a shorter diagnostic delay, and a better survival.

The infection rate was similar in the two groups. Thus, oral administration of ciprofloxacin is an attractive, cost-effective and safe alternative to prophylaxis in vascular patients capable of taking oral medication on the day of surgery.
