The outcome of 29 patients who underwent lung resection for treatment of metastatic malignant melanoma from January 1976 to November 1988 was studied. Twenty-two patients underwent total resection for cure of all apparent metastatic disease, whereas seven patients did not undergo total resection. Of the 22 patients who underwent curative resection, the median survival was 11 months, with a 2-year survival of 13.6% and a 5-year survival of 4.5%. ⋯ The difference in survival of the patients who underwent curative resection compared with palliative resection was statistically significant. The thickness of the primary cutaneous malignant melanoma, the presence of regional lymph node metastases, the disease-free interval from primary diagnosis to metastatic pulmonary disease, and whether one or two metastatic nodules were removed during curative lung resection were not statistically significant in altering survival. These results demonstrate that although prolonged survival for metastatic melanoma is rare, lung resection in selected patients may be associated with long-term survival.

The first known case report of a small-bowel obstruction caused by a long-term indwelling Foley catheter is presented. The balloon of the catheter passed into and obstructed the lumen of the distal ileum through a vesicoenteric fistula created by chronic irritation. With the exception of recurrent urinary-tract infections, complications of urinary catheters are rare. The patient presented a diagnostic dilemma that was solved with a preoperative computed tomographic scan.

Comparative Study
Transthoracic approach in the thoracic outlet syndrome: an alternate operative route for removal of the first rib.
This retrospective study compares the results of two surgical procedures, a transaxillary and a transthoracic (that is, anterolateral thoracotomy) approach, in the treatment of the thoracic outlet syndrome by first rib resection. After transaxillary first rib removal (13 cases), initially our procedure of choice, 84% of conditions were improved, 8% were unchanged, and 8% were worse after 1 year. One permanent, disabling brachial plexus injury occurred after this operation. ⋯ Although two female patients felt mild paresthesia of the mammary gland, no one has been made worse following this route. These two approaches have achieved similar results in the surgical management of this syndrome. Nevertheless, when first rib resection is indicated, our favored and recommended procedure is transthoracic, because this route appears less hazardous for brachial plexus damage.

Randomized Controlled Trial Clinical Trial
Antibiotic prophylaxis for surgery in morbidly obese patients.
The rate of wound infections in morbidly obese patients who underwent gastroplasty surgery at our institution was 16.5% compared with a rate of 2.5% in normal-weight patients who underwent clean-contaminated surgery. Both groups received 1 gm of cefazolin intramuscularly before surgery was performed. We hypothesized that this regimen of prophylaxis did not provide adequate tissue levels in the morbidly obese. ⋯ Only when the morbidly obese patient received 2 gm cefazolin were both the serum and adipose tissue levels adequate. For a 4-month period, all morbidly obese patients received 2 gm cefazolin prophylaxis, and the wound infection rate dropped to 5.6% compared with the previous rate of 16.5% (p less than 0.03). We conclude that antibiotic prophylaxis must be specially tailored to the needs of these obese patients.
