Long-term results of pectoralis major muscle transposition for infected sternotomy wounds.

During an 11.5-year period, 100 consecutive patients (79 male, 21 female) underwent repair of an infected sternotomy wound. Sixty-five patients had failed attempts at wound closure by other physicians. Median age was 61.5 years (range, 5 to 85 years). Reconstruction included muscle in 79 patients, omentum in 4, and both in 15. A total of 175 muscles were transposed, including 169 pectoralis major, 3 rectus abdominis, 2 external oblique, and 1 latissimus dorsi. Median number of operations was four (range, 1 to 11). Mechanical ventilation was required in 30 patients. Two perioperative deaths occurred, one related to sepsis. Median follow-up was 4.2 years (range, 1.3 to 13.5 years). Twenty-six patients had recurrent infection. Median time from our closure to recurrence was 5.5 months (range, 0.3 to 27.6 months). Cause of recurrence was inadequate removal of cartilage in 16 patients, bone in 6, and retained foreign body in 4. Eighteen patients had the wound reopened with further resection; 10 had another muscle or omentum transposition. There were 30 late deaths, only one related to recurrent infection. At the time of death or last follow-up, 92 patients had a healed chest wall. Transposition of the pectoralis major muscle remains an excellent method of management for infected sternotomy wounds. Failure is directly related to persistent infection of cartilage, bone, or retained foreign bodies.     

Primary tuberculous nasal polypi—A case report

Primary tuberculous pathology in nasolpolypi is a rare condition. A case of bilateral ethmoidal polypi with tubercular lesion diagnosed on histopathologlcal examination is being reported and the available relevant literature has been reviewed.     

Multiple primary lung cancers. Results of surgical treatment

During a 13-year period, multiple primary lung cancers were diagnosed in 80 consecutive patients. Forty-four patients had metachronous cancers. The initial pulmonary resection was lobectomy in 36 patients, bilobectomy in 3, pneumonectomy in 1, and wedge excision or segmentectomy in 4. The second pulmonary resection was lobectomy in 16 patients, bilobectomy in 2, completion pneumonectomy in 7, and wedge excision or segmentectomy in 19. There were two 30-day operative deaths (mortality rate, 4.5%). Actuarial 5- and 10-year survival rates after the first pulmonary resection for stage I disease were 55.2% and 27.0%, respectively. Five-year and 10-year survival rates for stage I disease after the second pulmonary resection were 41.0% and 31.5%, respectively. The remaining 36 patients had synchronous cancers. The pulmonary resection was lobectomy in 18 patients, bilobectomy in 3, pneumonectomy in 10, and wedge excision or segmentectomy in 8. There were two 30-day operative deaths (mortality rate, 5.6%). Actuarial overall 5- and 10-year survival rates after pulmonary resection were 15.7% and 13.8%, respectively. We conclude that an aggressive surgical approach is safe and warranted in most patients with multiple primary lung cancers and that the presence of synchronous primary cancers is ominous.     

The effectiveness of fibrin glue sealant for reducing experimental pulmonary ari leak

The effectiveness of fibrin glue as a biological sealant for pulmonary air leaks was determined in 16 dogs. A standardized pleural defect was made in the left lower lobe, and the quantity of air passing through a chest tube was assessed with a Collins respirometer. For the 8 randomly assigned control animals, the air leak decreased over 90 minutes from a mean of 1.4 L/min to a mean of 1.1 L/min (mean decrease, 19.8%). In the 8 randomly assigned fibrin glue-treated animals, the air leak decreased from a mean of 2.1 L/min to a mean of 0.5 L/min (mean decrease, 80.8%) (p less than 0.0001). Postoperative evaluation of survivors disclosed no increased adhesions in the glue-treated animals and complete resorption of the glue at 3 months. We conclude that in this animal model, fibrin glue reduced the size of pulmonary air leaks in the early period after thoracotomy and did not lead to increased intrapleural adhesions.     

Completion pneumonectomy: indications, complications, and results

From 1958 through 1985, a total of 113 consecutive patients had completion pneumonectomy (CP). Indications for pulmonary resection resulting in CP were lung cancer (LC) in 64 patients, pulmonary metastases (PM) in 20, and benign lung disease (BLD) in 29. Operative mortality was 12.4% (14 deaths) but varied according to the indication for CP. Mortality was 9.4% for LC, 0% for PM, and 27.6% for BLD. Forty-three patients (38.1%) had major complications (26 of 64 with LC, 40.6%; 1 of 20 with PM, 5.0%; and 16 of 29 with BLD, 55.2%). Five-year actuarial survival for patients with LC was 26.4% but varied according to stage. Five-year survival for patients with PM was 40.8% and with BLD was 27.2%. We conclude that CP for BLD carries marked operative mortality and morbidity, usually due to intense reaction around hilar structures and concurrent active infection or fistula. In contrast, CP for LC and PM can be performed with low mortality, acceptable morbidity, and gratifying long-term survival.     

糖化血清蛋白测定对糖尿病监控临床意义的探讨

目的：对临床确诊糖尿病患同时测定血清葡萄糖(Glu)及糖化血清蛋白(GSP)的含量，观察二的关系，以及糖化血清蛋白水平对于评价近期(2—3周)糖尿病患血糖在体内变化的临床意义进行了观察。方法：血清葡萄糖、糖化血清蛋白测定均采用酶法测定。结果：178例糖尿病患Glu、GSP均正常3l例占17．4％；Glu、GSP均增高107例占60．1％；Glu正常、GSP增高15例占8．43％；Glu增高、GSP正常25例占14％。结论：糖化血清蛋白的含量不受即时血糖的影响，二的变化不成比例性，对评价糖尿病患2～3周病情的控制是一项灵敏可靠的指标，尤其对于住院病人的治疗与监控有一定的意义。     

Solitary pulmonary nodule: CT evaluation of enhancement with iodinated contrast material--a preliminary report.

The authors hypothesized that the degree of contrast material enhancement of a pulmonary nodule, measured with computed tomography (CT), may indicate the likelihood of malignancy. Fifty-two patients with uncalcified solitary pulmonary nodules (diameter, 6-30 mm) were studied. Five single serial thin-section CT scans were obtained at 1-minute intervals after injection of 100 mL of nonionic contrast material. Twenty-two patients were excluded because the diagnosis was not clearly established: The observation period was less than 2 years, or the examination was technically inadequate. Malignant nodules were identified in 23 of the 30 remaining patients, and benign nodules were identified in seven. Within the first 2 minutes after the injection, all the malignant nodules had enhanced by 20 HU or greater (only one benign nodule had that degree of enhancement). The authors conclude that the degree of contrast material enhancement of pulmonary nodules as measured with CT may indicate the likelihood of malignancy.     

Pulmonary aspergilloma. Results of surgical treatment

Between 1953 and 1984, 53 patients (40 male and 13 female) underwent thoracotomy for treatment of pulmonary aspergilloma. The median age was 58 years (range 4 to 86 years). Either underlying lung disease or immunologic risk factors were present in 49 patients (92%). Twenty-one patients (31%) had simple aspergilloma and 32 (47%) had complex aspergilloma. The most common indication for operation was an indeterminate mass, hemoptysis, or severe cough. Lobectomy, wedge excision, and pneumonectomy were the most frequent operations. Complications occurred in 78% of patients with complex aspergilloma and in 33% of patients with simple aspergilloma (p = 0.002). Operative mortality was 5% (one death) in patients with simple aspergilloma and 34% (11 deaths) in patients with complex aspergilloma (p = 0.01). Cause of death was respiratory failure in four patients, underlying pulmonary disease in three, aspergillosis in two, and other conditions in three. At follow-up, 84% of operative survivors with simple aspergilloma were alive and well compared with 43% of those with complex aspergilloma. Although operative mortality in patients with complex aspergilloma was high, 67% of the survivors had a good long-term result in terms of absence of symptoms, but they frequently died of underlying disease. In contrast, operation in patients with simple aspergilloma was done with low risk, and approximately 90% of survivors had a good late result. Late appearance of contralateral disease did occur and argues for rigorous postoperative surveillance.
