Thoracic surgery.

Thoracic surgery is performed in dogs and cats for many reasons. Because it is performed less frequently than surgery on other body regions, and because the pathophysiologic effects of thoracotomy are life threatening, a good understanding of the principles of thoracic surgery is essential to success.

Serum interleukin-6, interleukin-8, hepatocyte growth factor, and nitric oxide changes during thoracic surgery.

Thoracic surgery creates a different environment from abdominal surgery in respect to the surgical procedure with pulmonary collapse under unilateral ventilation. Definitive evidence whether surgical trauma during thoracotomy is involved in postoperative pulmonary infections has not been clearly demonstrated. The objectives of this study were to evaluate the influence of surgical trauma during thoracotomy on postoperative infections and to investigate the clinical significance of postoperative humoral mediators in pulmonary infections after surgery. We measured serum interleukin-6 (IL-6), IL-8, hepatocyte growth factor (HGF), and nitric oxide (NO) levels in 27 patients undergoing thoracic surgery; the measurements were before and during thoracotomy, 60 minutes after reinflation, and after surgery. The patients were divided into three groups: lobectomy patients (group A), and esophagectomy patients without (group B) or with (group C) postoperative infections. The serum IL-6 and IL-8 levels in group C were markedly elevated 60 minutes after reinflation and were significantly higher than those in group A. The serum IL-8 levels during that period in group C were significantly higher than those in group B. The postoperative serum IL-6, IL-8, HGF, and NO levels were significantly higher in group c than in group B. Taken together, intraoperative hypercytokinemia, especially IL-8, following the thoracic procedure and subsequent reinflation preceded the clinical onset of postoperative infections. Hence postoperative serum IL-6, IL-8, and HGF levels may be useful predictors of infection after esophagectomy.

Lumbar epidural fentanyl analgesia after thoracic surgery.

Thoracic epidural fentanyl has been used successfully for postoperative analgesia in patients undergoing thoracic surgery. Prior investigators have suggested that increasing the administered dosage and volume of lumbar epidural fentanyl may increase the spread of analgesia. The feasibility of injecting a high volume (20 mL) of fentanyl into the lumbar epidural space for post-thoracic surgery analgesia was studied in 17 patients undergoing elective thoracotomy or sternotomy. All patients had a lumbar epidural catheter placed before induction of general anesthesia. No narcotic was administered during surgery. Thirty minutes before the conclusion of anesthesia, 200 micrograms of fentanyl in 16 mL of 0.9% saline was administered via the epidural route. In the intensive care unit (ICU), additional fentanyl in the same dosage and volume was injected when the patient complained of pain. Pain was scored on a linear analog scale pre-injection and 30 minutes post-injection. Arterial blood gases were obtained simultaneously. All patients experienced pain relief within 15 minutes of injection. No significant respiratory depression or hypercarbia was noted. Lumbar epidural fentanyl is a safe and practical alternative to thoracic epidural analgesia in the post-thoracic surgical patient.

Antibiotic prophylaxis in clean surgery: peripheral vascular surgery, noncardiovascular thoracic surgery, herniorrhaphy, and mastectomy.

Studies published in the English-language literature on the use of prophylactic systemic antibiotics in vascular surgery, noncardiovascular thoracic surgery, mastectomy, and herniorrhaphy were reviewed. The effectiveness of antibiotic prophylaxis in preventing deep and superficial wound infections in peripheral vascular surgery appears to be well documented, especially if prophylaxis is directed against Staphylococcus aureus. In clean thoracic surgery the evidence is equivocal, and no studies have sufficient statistical power to eliminate the possibility even of a 50% reduction in incidence. In herniorrhaphy and mastectomy some evidence from a much more powerful study suggests that antibiotic prophylaxis may result in a decrease of up to 50% in wound infections, but whether these data can be generalized uncritically to all clean wounds is still a matter of debate. Accordingly, only guarded recommendations can be made regarding the use of prophylactic antibiotics in procedures associated with a very low risk of serious infection.

Thoracic Surgery Workforce Report. The fourth report of the Thoracic Surgery Workforce Committee of The American Association for Thoracic Surgery and The Society of Thoracic Surgeons.

To determine demographics, practice patterns, and work volume of North American thoracic surgeons, we sent a detailed survey to all members of The American Association for Thoracic Surgery and The Society of Thoracic Surgeons between January and May 1993 to determine data for 1992; 3049 of 3487 (87%) thoracic surgeons responded and 2677 (88%) were in active practice. Ninety-seven percent were male and 3% female, with a mean age of 52 years. Sixty-five percent considered fee-for-service as their primary compensation mode. Only 24% do isolated subspecialty work: 2% pediatric cardiac surgery. 10% general thoracic surgery, and 12% adult cardiac surgery. Seventy-six percent of respondents do both cardiac and thoracic operations. Workload data for adult cardiac, pediatric cardiac, general thoracic, peripheral vascular, and pacemaker operations were requested. Volume data were cross-correlated with age, 10 geographic regions including Canada, type of practice, and type of compensation and were cross-checked by hospital discharge data for 1992. These data were compared with data from similar surveys performed in 1976, 1980, and 1985, under the auspices of the same two societies; these latter surveys used diplomates of the American Board of Thoracic Surgery as their database. Workloads have increased over previous surveys. Most surgeons do a wide variety of thoracic operations, and exclusive designations are in the minority.

Thoracic surgery manpower: the fourth manpower study of thoracic surgery: 1985 report of the Ad Hoc Committee on Manpower of The American Association for Thoracic Surgery and The Society of Thoracic Surgeons.

Responding to a survey about their practice in 1985, 2,969 (70%) Board-certified thoracic surgeons provided data that were compared with data from manpower surveys in 1980 and 1976. (table; see text) Thoracic surgeons were most active between ages 35 and 54 years when they accomplished 61% of all general thoracic and 85% of cardiac operations. Surgeons older than 50 years performed significantly more general thoracic operations than younger surgeons, and the younger group performed significantly more cardiac operations than their older counterparts. Solo practice continued to decline. In smaller referral areas, the number of general thoracic procedures per surgeon increased, but the number of cardiac operations have decreased compared with 1980. Overall, general thoracic and cardiac operations increased, but peripheral vascular procedures and pacemaker insertions decreased in almost all nine census regions. Fewer general thoracic and cardiac operations were performed per thoracic surgeon in the western United States than in central and eastern regions. In response to questions about work load, 55% believed that their clinical activity was satisfactory, 42% operated too little, and 3% operated too much. The 363 non-Thoracic Board-certified surgeons who responded performed 14% of general thoracic and 8% of cardiac surgery in 1985. During the first half of the 1980s, our specialty certified an average of 134 thoracic surgeons annually, which is higher than the 120 surgeons per year estimated to meet the projected demand.

Major thoracic surgery in octogenarians: the video-assisted thoracic surgery (VATS) approach.

BACKGROUND: Thoracic surgery is associated with a high morbidity and mortality rate in the elderly patient population. Appropriate management of thoracic diseases is often avoided because of the inherent risks associated with the access thoracotomy. The purpose of this study was to evaluate the perioperative outcomes of octogenarians who underwent video-assisted thoracic surgery (VATS) for a variety of thoracic conditions. METHODS: A retrospective chart review was done on all patients who were between 80 and 90 years of age and underwent elective VATS between January 1995 and August 2001. RESULTS: A total of 162 consecutive VATS procedures were performed in 157 patients. Comorbid conditions consistent with their advanced age included chronic obstructive pulmonary disease, hypertension, coronary artery disease, and diabetes. The procedures included 96 lung resections (53 lobectomies, 42 wedge/segment resections), 46 pleurectomies, 8 decortications, 8 mediastinal biopsies, 3 pericardial windows, and 1 drainage of hemothorax. The pathology included 76 primary lung cancers, 35 metastatic diseases, 37 benign conditions, 9 nesotheliomas, and 3 carcinoid tumors. The average operative time and length of hospital stay after surgery were 51 min and 2.6 days, respectively. There were 3 (1.9%) mortalities, 2 from cardiac complications and 1 from pneumonia. Two (1.2%) patients required reexploration for bleeding. Four (2.5%) cases were converted to open thoracotomy thirteen (8.0%) cases had an air leak, of which 11 were managed on an outpatient basis with a Heimlich valve. They were discharged from the hospital an average of 3.3 days postoperatively. CONCLUSION: With VATS, surgical therapy can be offered to octogenarians with a low morbidity and mortality rate, as well as a short hospital stay.

The third manpower study of thoracic surgery: 1980 report of the Ad Hoc Committee on Manpower of The American Association for Thoracic Surgery and The Society of Thoracic Surgeons.

An ad hoc committee was appointed by The Society of Thoracic Surgeons (STS) in 1977 in order to determine the available manpower and workload of thoracic surgeons in 1976. This committee conducted a survey of the professional activities and geographic location of all known surgeons certified by the American Board of Thoracic Surgery (ABTS) at that time. A summary of this study indicated the available and projected thoracic surgery manpower. The report also determined the present and projected health care needs of the population of the United States through 1993. Because thoracic surgery needs to continue to meet the health care needs of the United States in an appropriate yet economical fashion, the STS and The American Association for Thoracic Surgery (AATS) undertook a joint review to determine again the available manpower and its workload in calendar year 1980. In addition, this study compared its findings with the 1976 report in order to detect changes in the workload and need for thoracic surgical services. A questionnaire was mailed to 3,584 certified thoracic surgeons. There were 2,675 responses. The material was sent to the Academic Computer Services at George Washington University Medical Center for tabulation and data processing. This report summarizes the results of this survey. It also compares these data with those obtained in the 1976 study and, based on this information, attempts to project the thoracic surgery manpower needs in the next decade by using several hypothetical models.

The current role of video-assisted thoracic surgery (VATS) in the overall practice of thoracic surgery. A review of 207 cases.

From December 1991 to June 1995, video-assisted thoracic surgery (VATS) was performed on 207 patients at the Medical Center of Delaware with minimal complications and no mortality. A definitive diagnosis was made in all patients. Results with VATS procedures appear to be comparable to those with the standard open technique. Operating time was comparable to that with the open technique. Length of stay and pain and suffering were dramatically reduced compared with the open technique. We now consider VATS to be the preferred procedure in the following conditions: 1. Undiagnosed pulmonary infiltrate in the non-ventilator-dependent patient. 2. Indeterminate pulmonary nodule. 3. Undiagnosed disease of the pleural space. 4. Recurrent or persistent pneumothorax. 5. Mediastinal or pericardial cystic tumors. 6. Thoracic sympathectomy. 7. Selected patients requiring esophagocardiomyotomy. The utilization of VATS for resection of a pulmonary mass in patients with compromised pulmonary status (i.e., FEV < 1) is being studied.

Dissemination of malignant tumors after video-assisted thoracic surgery: a report of twenty-one cases. The Video-Assisted Thoracic Surgery Study Group.

Video-assisted thoracic surgical techniques are widely used for biopsy and resection of thoracic tumors, but studies of long-term outcomes have not been reported. Dissemination of tumor by these techniques is a potential hazard. Therefore we surveyed the surgical members of the Video-Assisted Thoracic Surgery Study Group to determine whether tumor implants thought to be directly related to video-assisted techniques had occurred. Surgeons reported 21 cases. The sites of recurrence were the incision (n = 14), pulmonary staple line (n = 2), pleura (n = 2), both staple line and incision (n = 1), both pleura and incision (n = 1), and both pleura and staple line (n = 1). Review of these cases illustrates the pitfalls of present video-assisted techniques for malignant tumors of the thorax.
