ABSTRACT

BACKGROUND: Postoperative air leaks are a major cause of morbidity after lung resections. This study was designed to evaluate the efficacy and safety of a new synthetic, bioresorbable surgical sealant in preventing air leaks after pulmonary resection. METHODS: In a multicenter trial, 172 patients undergoing thoracotomy were randomized intraoperatively in a 2:1 ratio to receive surgical sealant applied to sites at risk for air leak after standard methods of lung closure (treatment group) or to have standard lung closure only (control group). The primary outcome variable was the percentage of patients free of air leakage throughout hospitalization. Secondary outcome variables were the control of air leaks intraoperatively and the time to postoperative air leak cessation. Time to chest tube removal, time to hospital discharge, and safety outcomes were also evaluated. RESULTS: Air leaks were identified before randomization in 89 of 117 patients in the treatment group and in 39 of 55 patients in the control group. Application of the sealant resulted in control of air leaks in 92% of treated patients (p < or = 0.001). A significantly higher percentage of treated patients than control patients remained free of air leaks during hospitalization (39% versus 11%, p < or =0.001). The mean times to last observable air leak were 30.9 hours in the treatment group and 52.3 hours in the control group (p = 0.006). In the treatment group, trends were observed for reduced time to chest tube removal and earlier discharge. No significant difference was identified in postoperative morbidity and mortality between the two groups. CONCLUSIONS: Air leaks after lung resection occur in most patients. The application of this novel surgical sealant appears to be effective and safe in preventing postoperative air leaks.

ABSTRACT

BACKGROUND: Palliation of malignant dysphagia can be achieved by insertion of an endoprosthesis. Recently, metallic self-expanding prostheses have been introduced that offer the advantage of a lower complication rate over their plastic counterpart. METHODS: Thirteen patients with dysphagia due to inoperable carcinoma of the esophagus were treated with coated Wallstent (Schneider (USA) Inc, Minneapolis, MN) endoprostheses, which were placed under fluoroscopic control. All patients were given general anesthesia during the procedure. RESULTS: After successful insertion of all endoprostheses, the dysphagia of 12 of the patients improved while in the hospital. Average length of stay was 4.4 days. Two patients required a second stent because of migration or tumor overgrowth. Seven patients died with a mean survival of 54 days (range, 14 to 144 days), and 6 are alive a mean of 112 days (range, 32 to 263 days) after treatment. CONCLUSIONS: Coated Wallstent insertion is an effective, single treatment that quickly improves the patients' quality of life. Its effect on survival is yet to be established when used as a last resort in patients with inoperable esophageal carcinoma and poor general condition.

ABSTRACT

Four patients with chronic empyema after pneumonectomy have undergone successful obliteration of the empyema tract with a deepithelialized transverse rectus abdominis myocutaneous flap. The deepithelialized skin island has provided sufficient bulk for tract obliteration. Rotation of the skin island into the long axis of the rectus muscle has added considerable length to this flap, allowing it to reach the apex of the thoracic cavity. A recurrent loculation developed 4 months after the obliteration procedure in one patient. This was successfully treated with open pleural drainage and a second Clagett procedure. Over a mean follow-up period of 35 months, all four patients are free of further infectious sequelae. Chest roentgenograms have confirmed eradication of the tracts in all four patients.

ABSTRACT

The management of chylothorax requires a thorough understanding of the anatomy and pathophysiology of the major thoracic lymphatics, prompt diagnosis, and (with rare exception) conservative management, including evacuation of the pleural space, nutritional support, and measures to reduce chyle production. A minority of chylothoraces will fail to resolve with these measures. Surgical intervention is then required to prevent chronic metabolic deterioration and death.

ABSTRACT

A 41-year-old woman with recurrent attacks of postprandial abdominal pain was found on endoscopic retrograde cholangiopancreatography and subsequent computed tomographic scan to have an enteric duplication within the substance of the pancreas with communication to the pancreatic duct. Celiotomy demonstrated a noncontiguous gastric duplication cyst. Internal drainage was curative.
