OBJECTIVE: We streamlined our care after pulmonary resection for quality and cost-effectiveness. METHODS: A single surgeon performed 500 consecutive pulmonary resections through a thoracotomy over a 2(3/4)-year period in a university setting. Patients were extubated in the operating room and sent directly to their hospital room. Chest tubes were placed to water seal and removed on postoperative day 2 if there was no air leak and drainage was less then 400 mL/d. Epidural catheters were used and removed by postoperative day 2. The plan for each day and discharge on postoperative day 3 or 4 was reviewed with the patients and families daily during rounds. The patient went home the day the last chest tube was removed. Persistent air leaks were treated with Heimlich valves. RESULTS: There were 500 patients (338 men), with a median age of 58 years (range, 3-87 years). Of these patients, 293 had pre-existing conditions. Seventy-three (15%) patients had been denied operations by at least one other surgeon. Four hundred nineteen (84%) patients had successful placement of a functioning preoperative epidural catheter. Pneumonectomy was performed in 32 (6%) patients, segmentectomy was performed in 16 (3%) patients, and lobectomy, sleeve lobectomy, and/or bilobectomy was performed in 194 (39%) patients. Nonanatomic resections were performed for metastasectomy. This included a single wedge resection in 161 (32%) patients and multiple wedge resections in 97 (19%) patients. A total of 482 (96%) patients were extubated in the operating room, and 380 (76%) patients were sent to their hospital room. The remaining 120 patients went to the intensive care unit for a median of 1 day (range, 1-41 days). Complications occurred in 107 (21%) patients, and operative mortality was 2.0%. Median day of discharge was postoperative day 4 (range, 2-119 days). A total of 327 (65%) patients left the hospital on postoperative day 4 or sooner. By survey, 97% of patients had excellent or good satisfaction with their care at hospital discharge, and 91% were extremely happy or satisfied at the 2-week follow-up contact. CONCLUSIONS: Most patients who undergo elective pulmonary resection can be extubated immediately after the operation, go directly to their room and avoid the intensive care unit, be discharged on postoperative day 3 or 4, and have minimal morbidity and mortality with high satisfaction both at discharge and at the 2-week follow-up contact. Techniques that seem to accomplish this include the following: the use of a water seal, removal of epidural catheters on postoperative day 2, early chest tube management, treatment of persistent air leaks with Heimlich valves, and daily reinforcement of the planned events for each day, as well as on the date of discharge with the patients and their families.

BACKGROUND: Surgeons treat air leaks differently. Our goal was to evaluate whether it is better to place chest tubes on suction or water seal for stopping air leaks after pulmonary surgery. A second goal was to evaluate a new classification system for air leaks that we developed. METHODS: Patients were prospectively randomized before surgery to receive suction or water seal to their chest tubes on postoperative day (POD) #2. Air leaks were described and quantified daily by a classification system and a leak meter. The air-leak meter scored leaks from 1 (least) to 7 (greatest). The group randomized to water seal stayed on water seal unless a pneumothorax developed. RESULTS: On POD #2, 33 of 140 patients had an air leak. Eighteen patients had been preoperatively randomized to water seal and 15 to suction. Air leaks resolved in 12 (67%) of the water seal patients by the morning of POD #3. All 6 patients whose air leak did not stop had a leak that was 4/7 or greater (p < 0.0001) on the leak meter. Of the 15 patients randomized to suction, only 1 patient's air leak (7%) resolved by the morning of POD #3. The randomization aspect of the trial was ended and statistical analysis showed water seal was superior (p = 0.001). The remaining 14 patients were then placed to water seal and by the morning of POD #4, 13 patients' leaks had stopped. Of the 32 total patients placed to seal, 7 (22%) developed a pneumothorax and 6 of these 7 patients had leaks that were 4/7 or greater (p = 0.001). CONCLUSIONS: Placing chest tubes on water seal seems superior to wall suction for stopping air leaks after pulmonary resection. However, water seal does not stop expiratory leaks that are 4/7 or greater. Pneumothorax may occur when chest tubes are placed on seal with leaks this large.

Pryce's type I intralobar sequestration, in which a region of lung exhibits tracheobronchial continuity and aberrant systemic arterial supply, is most frequently asymptomatic and discovered incidentally. While hemoptysis may be a common presenting symptom, massive hemoptysis is rarely seen. We document a case of a 58-year-old man, previously asymptomatic, whose initial presentation was that of massive hemoptysis. The radiographic, intraoperative and pathologic findings in our patient confirm that his sequestration was of Pryce's type I. Ann Diagn Pathol 5:91-95, 2001.

This case report presents the unusual characteristics of a neuroendocrine thymic carcinoma that probably has metastasized to the left side of the interatrial septum from a primary thymic site.

Bronchopleural fistula (BPF) is a life-threatening complication after pulmonary resection. The incidence varies from 4.5% to 20% after pneumonectomy and is only 0.5% after lobectomy. Certain patient characteristics increase this incidence. These include preoperative radiation to the chest, destroyed or infected lung from inflammatory disease, immunocompromised host, and insulin-dependent diabetes. Certain surgical techniques also increase the incidence. These include pneumonectomy, right-sided pneumonectomy, a long bronchial stump, residual cancer at the bronchial margin, devascularization of the bronchial stump, prolonged ventilation, or reintubation after resection and surgical inexperience. The best treatment of a BPF is prevention. Prevention centers around meticulous surgical technique and the liberal use of prophylactic, pedicled muscle flaps for the patient at increased risk. Survival of BPF depends on a high index of suspicion, early diagnosis, and aggressive surgical intervention.

BACKGROUND: Removal of the right middle and lower lobes often leaves a pleural space problem that can cause prolonged air leaks. METHODS: A single surgeon prospectively randomized 16 patients who underwent bilobectomy. Eight patients had 1200 mL of air injected under the right hemidiaphragm after bilobectomy and 8 did not. The air was injected through a small transdiaphragmatic opening made in the right hemidiaphragm at the time of pulmonary resection. RESULTS: The age of the patients, preoperative pulmonary function, preoperative comorbidities, indications for surgery, and final pathology were not significantly different between the two groups. On postoperative day #1, a pneumothorax was present in 1 patient (13%) in the pneumoperitoneum group (P group) and in 4 patients (50%) in the nonpneumoperitoneum group (N-P group). On postoperative day 1, an air leak was present in 1 patient (13%) in the P group and 5 patients (63%) in the N-P group (p < 0.001). By the third postoperative day, no patient in the P group had an air leak; however, a leak was present in 4 patients (50%) in the N-P group (p < 0.001). Median hospital stay in the P group was 4 days (range, 3 to 6 days), compared with 6 days (range, 4 to 8 days) in the N-P group (p < 0.001). Three patients in the N-P group were sent home with a Heimlich valve. There was no operative mortality and no complications from the pneumoperitoneum. CONCLUSIONS: We conclude that pneumoperitoneum after bilobectomy is safe and easy to do. It decreases the incidence of air leaks and of pneumothoraces and shortens hospital stay without increasing morbidity. We recommend pneumoperitoneum after bilobectomy at the time of thoracotomy, especially if there are residual small air leaks that cannot be sealed before chest closure.
