ABSTRACT

Glomus tumors are uncommon. A review of the literature for tracheobronchial glomus tumors revealed 13 tracheal glomus tumors. The diagnosis may be elusive and so the true incidence of tracheobronchial glomus tumors may be greater than that reported. Three of the 14 glomus tumors were initially believed to be carcinoid. Glomus tumors should be included in the differential diagnosis of tracheobronchial tumors.

ABSTRACT

BACKGROUND: The vast majority of parathyroid glands in hyperparathyroidism can be resected through a cervical approach. In approximately 2% of the cases, the ectopic gland is in the mediastinum in a location that requires a thoracic approach. METHODS: We report 7 such cases that were resected using video-assisted thoracic surgery to avoid the need for an open surgical procedure. RESULTS: All glands were successfully identified preoperatively and subsequently resected. Hospital stay averaged less than 3 days with only one minor complication. CONCLUSIONS: Ectopic mediastinal parathyroid glands may be safely and accurately resected using video-assisted thoracic surgery to avoid open approaches.

ABSTRACT

Video-assisted thoracic surgery (VATS) may be used for resection of posterior mediastinal tumors to avoid thoracotomy and shorten hospital stay. Between October 1990 and June 1998, 23 patients had VATS resection of posterior neurogenic tumors. The 14 females and 9 males ranged in age from 14 months to 70 years, with a median of 35 years. Operation time ranged from 30 to 120 minutes (median, 83), and intraoperative complications were limited to minor problems as well as conversion to thoracotomy to enhance complete tumor resection in four cases. Tumor pathology included nerve sheath origin (20) and autonomic ganglia (3). There was only one malignant schwannoma. Tumor size ranged from 0.7 to 13 cm in diameter. Median chest tube days was 1 day (range, 1-4), and hospital stay was 2 days (range, 1-9). Postoperative complications included transient paresthesia (three cases), ileus (two cases), pleural effusion (one case), and transient intercostal pain (one case). Posterior neurogenic tumors may be resected safely using video-assisted techniques. Conversion to thoracotomy to enhance complete resection is both possible and encouraged. The use of VATS seems to decrease hospital stay and minimize postoperative complications. In posterior neurogenic tumors without tumor extension to the spinal canal, VATS has become our preferred method for resection.

ABSTRACT

BACKGROUND: Lung volume reduction operations have been shown to improve the quality of life and functional status of some patients with end-stage emphysema. METHODS: Because of a perceived increase in the occurrence of postoperative gastrointestinal (GI) complications, we reviewed our experience in 287 patients who had lung volume reduction operations to determine the frequency of GI complications and to identify risk factors. RESULTS: Using a broad definition of postoperative GI complications (nausea, vomiting, abdominal distension, gastroesophageal reflux, diarrhea, constipation) there were 137 complications in 67 patients (23%). More severe GI complications (bowel ischemia, GI bleeding, perforation, ulceration, ileus, colitis, cholecystitis, pancreatitis) occurred 49 times in 27 patients (9.4%). Seven of the 27 patients required abdominal operations. Risk factors identified as predictive of severe complications include diabetes (p = 0.0003), lower preoperative hematocrit (p = 0.01), steroid use (p = 0.02), and use of parenteral meperidine analgesic (p = 0.002). Stepwise logistic regression demonstrated that diabetes was 7.02 times more likely to produce severe complications. Other risk factors included steroids (2.81), number of different pain medications (2.59), hematocrit decrease of 5% (1.96), and hematocrit decrease of 1% (1.14). In the patients with severe GI complications there were six of 27 (22%) hospital deaths compared with five of 260 (2%) in those without GI complications (p = 0.0001). CONCLUSIONS: Severe GI complications in patients with emphysema who had lung volume reduction operations are not uncommon (9.4%) and influence the perioperative mortality rate. Heightened awareness to identified risk factors will allow earlier recognition, prevention, and perhaps decrease morbidity and mortality rates in these high-risk patients.

ABSTRACT

Lung volume reduction surgery (LVRS) has been a popular procedure since the early 1990s. It appears that there has developed a consensus in the literature that the ideal patient is one with evidence of marked hyperinflation and heterogenous disease. In this patient profile, LVRS has produced excellent results with respect to lung function and improved exercise tolerance. General areas of controversy are discussed which include the role of lasers; unilateral versus bilateral procedures; the role of a staged unilateral procedure; and which surgical route is best for patients. The existing literature is reviewed on these issues.

ABSTRACT

BACKGROUND: It has been suggested that bilateral thoracoscopic lung volume reduction (BTLVR) yields significantly better long-term survival than unilateral thoracoscopic lung volume reduction (UTLVR). METHODS: All perioperative data were collected at the time of the procedure. Follow-up data were obtained during office visits or by telephone. RESULTS: A total of 673 patients underwent thoracoscopic LVR: 343 had either simultaneous or staged BTLVR and 330, UTLVR. As of July 1998, follow-up was available on 667 (99%) of the 673 patients with a mean follow-up of 24.3 months. The patients in the BTLVR group were significantly younger (62.6+/-8.0 years versus 65.4+/-8.1 years; p < 0.0001), had a higher preoperative arterial oxygen tension (69.7+/-12 mm Hg versus 65.3+/-11 mm Hg; p < 0.0001), and had a superior preoperative 6-minute walk performance (279.9+/-93.6 m [933+/-312 feet] versus 244.5+/-101.4 m [815+/-338 feet] p < 0.0001). There was no difference in the operative mortality rate between the two groups (UTLVR, 5.1%, and BTLVR, 7%). Actuarial survival rates for the UTLVR group at 1 year, 2 years, and 3 years were 86%, 75%, and 69%, respectively versus 90%, 81%, and 74%, respectively, for the BTLVR group (p = not significant). CONCLUSIONS: Contrary to previous reports, survival after BTLVR was not superior to that after UTLVR even though the former group appeared to have a lower risk preoperatively because of younger age, higher arterial oxygen tension, more advantageous anatomy, and better functional status. Despite thoracoscopic LVR, the actuarial mortality rate approached 30% at 3 years, and this calls into question whether this procedure offers any survival advantage to patients with end-stage emphysema.

ABSTRACT

BACKGROUND: Lung volume reduction operations have proved beneficial for emphysematous patients, but questions remain about the role of a unilateral procedure. METHODS: Fifty patients were prospectively enrolled in a lung volume reduction surgery program for emphysema with staged unilateral video-assisted thoracoscopic procedures (VATS group). These patients were compared with 29 patients having bilateral lung volume reduction procedures by median sternotomy. RESULTS: The VATS group was slightly older and had shorter 6-minute walk distances, but otherwise the two groups were similar. Hospital stays were shorter for each unilateral VATS procedure, but the total of the two hospital stays was longer than the stay for the sternotomy group (21.1 versus 14.8 days). Complications were comparable, there were no in-hospital deaths, and there was significant difference in the 1-year mortality rate (VATS, 6% versus sternotomy, 13.8%; p = 0.137). Functional test results were comparable between the groups with improvements in percent predicted forced expiratory volume in 1 second (VATS, 41%, and sternotomy, 40%), 6-minute walk distances (VATS, 48%, and sternotomy, 26%), dyspnea scores, and acid base measurements. CONCLUSIONS: Staged lung volume reduction operations do not appear to offer any measurable advantages over a single hospitalization and bilateral lung volume reduction procedures.

ABSTRACT

BACKGROUND: A previous operation is generally considered to be a relative contraindication to the minimal access approach. We reviewed our combined experience from three centers with video-assisted thoracic surgery on reoperated chests. METHODS: From September 1992 to December 1996, 2,477 patients underwent video-assisted thoracic surgery of whom 40 patients (33 men; age range, 9 to 78 years) had prior operations on the ipsilateral side of the chest: 23 after prior open procedures (22 thoracotomies, 1 median sternotomy) and 17 after video-assisted thoracic surgery. The second procedures consisted of bullectomy or bulla ligation (8), mediastinal and hilar mass biopsy (8), wedge lung resection (6), pericardial window (5), lung volume reduction (4), redo thoracodorsal sympathectomy (3), talc insufflation alone (3), decortication (2), and suturing of a pleural rent (1). RESULTS: Adhesions were noted in all patients ranging from minimal to strong fibrous adhesions. However, in only 2 patients (5%) were the procedures abandoned because of adhesions. Video-assisted thoracic surgery was safely completed in all other patients. There was no mortality or intraoperative complications and mean hospital stay was 5.1 +/- 3.2 days (range, 0 to 17 days). CONCLUSIONS: Video-assisted thoracic surgery on reoperated chests is feasible and does not carry a higher morbidity or mortality compared with first-time operations, even though it may be technically more difficult. Experience and clinical judgment, however, are required to select these patients for reoperation with video-assisted thoracic surgery.

ABSTRACT

BACKGROUND: We explored the efficacy of laparoscopic fundoplication (LF) in patients with uncomplicated, medically recalcitrant pathologic gastroesophageal reflux disease (GERD) for whom we previously would have recommended open surgical repair. METHODS: From January 1994 to January 1998, we performed LF on 150 patients (80 men and 70 women) with GERD recalcitrant to maximal medical therapy. No patient suffered from esophageal stricture or epithelial dysplasia; however 16% (24 of 150) had benign Barrett's mucosa. Preoperative esophageal manometry and 24-hour pH testing were obtained in 93% (139 of 150) and 89% (134 of 150) of patients, respectively. Nissen LF (n = 123), Toupet LF (n = 26), or Dor LF (n = 1) were accomplished over a large (54 F) intraesophageal bougie. Preoperative (1 month) and postoperative (>6 month) symptom scoring were assessed on a 0 to 10 scale. Thirty-eight patients with a greater than 6-month postoperative period had manometry and pH studies performed. RESULTS: The laparoscopic approach was successful in 99% (148 of 150) of patients, and there has been no mortality. Operative time was 160+/-59 minutes. Open conversion was required for 2 patients: because of difficulty with dissection owing to adhesions in 1 case and due to perforation in another. Reoperation was required for 5 patients (1 paraesophageal, 2 dysphagia, 2 recurrent reflux). Major postoperative complications involved stroke and pancreatitis in 1 patient each. Mean hospital stay was 2.6+/-1.2 days, full activity resumed by 7 days. Postoperative esophageal pH testing among 38 patients tested more than 6 months after operation demonstrated normal esophageal acid exposure in all but 2. GERD symptoms were relieved at 1 month, 6 months, and after 1 year in 95% (128 of 135), 94% (99 of 105), and 93% (65 of 70) of patients, respectively. CONCLUSIONS: Intermediate-term results with LF suggest this to be a reasonable approach to surgical management of medically recalcitrant uncomplicated GERD. Thoracic surgeons interested in GERD should become familiar with minimally invasive surgical approaches.

ABSTRACT

BACKGROUND: The risk of lung cancer is increased with cigarette smoking and obstructive lung disease. Patients having a lung volume reduction operation represent a high-risk population for cancer. METHODS: Between March 1994 and December 1996, 281 patients underwent a lung volume reduction operation. All had severe obstructive lung disease with hyperinflation. The incidence of lung nodules and their management were addressed. RESULTS: Of the 281 patients, 39.5% had at least one lung nodule identified. Fifty-two nodules had typical benign calcification patterns. Of the remaining nodules, 78 were resected and 20 were followed up. Seventeen nodules resected were cancerous, of which 13 were primary lung cancers. Of the resected nodules there were 28 nodules not identified by the preoperative radiologic evaluation. CONCLUSIONS: Nodules are frequently seen in patients undergoing lung volume reduction operations. The overall incidence of cancer was 6.4%, with several only identified in the pathologic examination. Survival at short follow-up has been excellent for those with primary lung cancer. Nodules seen in this group of patients should be aggressively diagnosed and managed.

ABSTRACT

BACKGROUND: Surgical procedures for emphysema have been proposed and in many settings resulted in significant improvement in dyspnea and function. The most prevalent surgical problem in all series is prolonged postoperative air leak. METHODS: One hundred twenty-three patients undergoing stapled thoracoscopic unilateral lung volume reduction operation were prospectively randomized to receive either no buttressing of their staple lines or buttressing of all staple lines with bovine pericardial strips. RESULTS: The two groups were comparable in preoperative risks and in the severity of their emphysema. Postoperative complications were identical in the two groups with respect to pneumonia, empyema, and wound infection; however, there was a significant difference in the duration of postoperative air leaks. Those having the pericardial strips used to buttress their staple lines had chest tubes removed 2.5 days sooner and were discharged from the hospital 2.8 days sooner as a result. The cost data revealed that because of the cost of the pericardial sleeves, the overall hospital charges were almost identical for the two groups ($22,108 bovine, $22,060 no bovine) in spite of the shortened hospital stay. CONCLUSIONS: The use of bovine pericardial sleeves to buttress the staple lines in thoracoscopic unilateral lung volume reduction operation results in a shorter duration of postoperative air leaks. Total hospital charges were comparable in the two groups as the 2.8 days saved in the hospital were offset by the cost of the pericardial sleeves.

ABSTRACT

BACKGROUND: The role of nonanatomic wedge resection in the management of stage I (T1 N0 M0) non-small-cell lung cancer continues to be debated against the present gold standard of care--anatomic lobectomy. METHODS: We analyzed the results of 219 consecutive patients with pathologic stage I (T1 N0 M0) non-small-cell lung cancer who underwent open wedge resection (n = 42), video-assisted wedge resection (n = 60), and lobectomy (n = 117) to assess morbidity, recurrence, and survival differences between these approaches. RESULTS: There were no differences among the three groups with regard to histologic tumor type. Analysis demonstrated the wedge resection groups to be significantly older and to have reduced pulmonary function despite a higher incidence of treatment for chronic obstructive pulmonary disease when compared with patients having lobectomy. The mean hospital stay was significantly less in the wedge resection groups. There were no operative deaths among patients having wedge resection; however, a 3% operative mortality occurred among patients having lobectomy (p = 0.20). Kaplan-Meier survival curves were nearly identical at 1 year (open wedge resection, 94%; video-assisted wedge resection, 95%; lobectomy, 91%). At 5 years survival was 58% for patients having open wedge resection, 65% for those having video-assisted wedge resection, and 70% for those having lobectomy. Log rank testing demonstrated significant differences between the survival curves during the 5-year period of study (p = 0.02). This difference was a result of a significantly greater non-cancer-related death rate by 5 years among patients having wedge resection (38% vs 18% for those having lobectomy; p = 0.014). CONCLUSION: Wedge resection, done by open thoracotomy or video-assisted techniques, appears to be a viable "compromise" surgical treatment of stage I (T1 N0 M0) non-small-cell lung cancer for patients with cardiopulmonary physiologic impairment. Because of the increased risk for local recurrence, anatomic lobectomy remains the surgical treatment of choice for patients with stage I non-small-cell lung cancer who have adequate physiologic reserve.

ABSTRACT

The prevalence and malignant potential of pulmonary lesions found preoperatively in patients undergoing coronary artery bypass grafting (CABG) surgery are poorly defined. In a review of 3364 consecutive patients undergoing CABG, 191 (5%) were found to have pulmonary lesions. Granulomatous disease was suspected in all patients who had only calcified lesions (n = 151). These were empirically observed with no changes seen at follow-up. The 40 patients with noncalcified lesions (NCLs) were managed variously. Twenty patients underwent resection of the suspicious pulmonary lesion at the time of cardiac surgery. One patient underwent wedge resection of a pulmonary lesion (benign granuloma) 4 days before CABG. Eighteen patients underwent concomitant pulmonary resection and CABG through the median sternotomy (7 benign, 11 malignant). A delayed pneumonectomy was performed 17 days after CABG in another patient. Three of 40 patients died during the perioperative period without pathologic diagnosis. The remaining 17 were followed with serial roentgenograms. Three of 17 (18%) had lesional enlargement in the follow-up period their lesions were found to be malignant. The remaining 14 patients have been observed without surgical intervention now with a mean follow-up of 5.7 years (range, 20 months to 13 years). The prevalence of malignancy in lesions found on CABG preoperative chest roentgenograms was 15 out of 191 (7.8%); however, among patients with NCL the prevalence of malignancy was 15 out of 40 (37%), and malignancy was present in 12/13 (92%) of patients with NCLs that were >/= 2 cm in diameter. When malignancy is diagnosed in an NCL before CABG surgery, the decision to proceed with CABG should be based upon the coronary pathophysiology and the stage and cell type of the malignancy. Concomitant CABG and pulmonary resection is possible in most cases; however, we prefer a staged resection of all newly diagnosed NCLs when these are identified in patients requiring emergent revascularization or when these lesions are difficult to access through sternotomy. The mortality rate may be slightly increased in patients having concomitant procedures (5.47%) versus isolated CABG (3%). The incidence of malignancy in these NCLs is related to size. If a staged resection is not undertaken after CABG, careful observation of NCLs is important, as 18 per cent of these so managed were ultimately found to be malignant.

ABSTRACT

Video-assisted thoracic surgery has been widely used in the treatment of spontaneous pneumothorax despite a paucity of data regarding the relative safety and long-term efficacy for this procedure. We reviewed 113 consecutive patients (68 male and 45 female patients, aged 15 to 92 years, mean 35.1) who underwent 121 video-assisted thoracic surgical procedures during 119 hospitalizations from 1991 through 1993. Recurrent ipsilateral pneumothorax was the most frequent indication for surgery and occurred in 77 patients (65%). The most common method of management was stapling of an identified bleb in the lung, which was undertaken in 105 (87%) patients. No operative deaths occurred. Complications included an air leak lasting longer than 5 days in 10 (8%) patients, two of whom required second procedures for definitive management. No episodes of postoperative bleeding or empyema occurred. The postoperative stay ranged from 1 day to 39 days (median 3 days, average 4.3 days) and 99 patients (84%) were discharged within 5 days. Mean follow-up was 13.1 months and ranged from 1 to 34 months. Eleven patients (10%) were lost to follow-up. Ipsilateral pneumothorax recurred after five of 121 procedures (4.1%). Twelve perioperative parameters (age, gender, race, smoking history, site of pneumothorax, severity of pneumothorax, operative indications, number of blebs, site of blebs, bleb ablation, method of pleurodesis, and prolonged postoperative air leak) were entered into univariate and multivariate analysis to identify significant independent predictors of recurrence. The only independent predictor of recurrence was the failure to identify and ablate a bleb at operation, which resulted in a 23% recurrence rate versus a 1.8% rate in those with ablated blebs (p < 0.001). These data suggest that video-assisted thoracic surgery is a viable alternative to thoracotomy for the treatment of recurrent spontaneous pneumothorax. It results in a short hospital stay, low morbidity, high patient acceptance, and a low rate of recurrence.

ABSTRACT

Over a 13-year period, 668 patients 70 years of age or older underwent isolated primary coronary artery bypass grafting at our institution. There were 472 men and 196 women, ranging from 70 to 90 years of age (median age, 74 years). Hospital mortality was 5.2% (35/668). In patients 70 to 79 years of age, hospital mortality was 4.2% (25/600), whereas in patients 80 years of age or older, mortality was 14.7% (10/68; p < 0.001). Twenty-seven clinical or hemodynamic variables hypothesized as predictors of operative mortality were examined. Mortality was higher in women than in men (9% versus 3.6%; p = 0.006). Those who died were a mean of 3 years older (77 versus 74 years old; p < 0.05) and were more likely to have unstable angina or Canadian class III or IV angina (p < 0.01). Patients requiring urgent operations, preoperative intraaortic balloon assist, intravenous nitroglycerin, or inotropic agents, and those with preoperative hypotension or cardiac arrest were most likely to die in the hospital (p < 0.001). Multivariate logistic regression analysis revealed advancing age, female sex, bypass time, urgency of operation, preoperative cardiac arrest, and unstable angina as primary determinants of mortality (p < 0.05). Although mortality after coronary artery bypass grafting increases with age, the greatest risk of death is in the acutely ill patient with few options for management other than surgical intervention.

ABSTRACT

Advances in myocardial preservation have led to improved patient survival after open heart operations. However, few studies have detailed the nature of national or regional patterns of cardioplegia use. To determine the regional pattern, all open heart surgery programs in Missouri were surveyed. During 1 year, it was found that cardioplegia was administered to 8,382 patients by 61 cardiothoracic surgeons at ten academic affiliated hospitals and 16 nonteaching hospitals. All cardioplegic solutions were hospital produced. Of 13 crystalloid solutions, 11 differed from one another and eight were intracellular formulations. Of 28 multidose blood-based cardioplegic solutions, there were 23 different mixtures. Most crystalloid (69%) and blood-based (89%) solutions differed substantially from commonly reported formulations. The incidences of the various additives to crystalloid solutions were as follows: bicarbonate, 92%; glucose, 69%; lidocaine, 54%; mannitol, 46%; magnesium, 31%; calcium, 23%; methylprednisolone, 15%; heparin, 8%; and acetate, 8%. Of the common blood-based cardioplegic solution additives, the following incidences were observed: glucose, 79%; bicarbonate, 43%; trishydroxyaminomethane, 36%; acetate, 29%; magnesium, 29%; procaine (or lidocaine), 25%; citrate-phosphate-dextrose, 18%; mannitol/albumin, 14%; nitroglycerin, 11%; glutamate/aspartate, 11%; calcium, 7%; insulin, 3%; and methylprednisolone, 3%. No calcium channel blocker or high-energy phosphate additives were reported. We conclude that many different cardioplegic admixtures that have not been tested experimentally are used routinely in clinical practice, presumably with acceptable results. Because the salutary effects of induced cardiac arrest and hypothermia may mask suboptimal solutions, further study of customized cardioplegia should be considered, particularly with regard to high-risk patients.

ABSTRACT

We have used the Sarns centrifugal pump for uni- or biventricular assist in 58 patients with postcardiotomy cardiogenic shock. This device utilizes a spinning impeller pump that is magnetically coupled to a motor imparting rotary motion to incoming perfusate. Nine patients (16%) experienced 22 device failures, which consisted of a nonvisible disruption of the seal within the pumphead. This allowed fluid to accumulate between the pumphead and the motor necessitating change of the pumphead. The time to seal disruption was 10-149 h (median 48). Of the 22 seal disruptions, 18 occurred in 73 left ventricular pumps (25%), and 4 occurred in 38 right ventricular pumps (11%) p = 0.015. Left ventricular pumps failed at 10-144 h (median 48), and right ventricular pumps failed at 48-149 h (median 83) p = 0.02. The Sarns centrifugal pump is dependable for its intended use of cardiopulmonary perfusion. However, when used for postcardiotomy assist, seal disruption should be expected. It occurs sooner and is more common during left ventricular assist. We recommend inspection of the magnet chamber for evidence of seal disruption every 12 h with left ventricular assist and every 24 h with right ventricular assist.

ABSTRACT

Appropriate interventional treatment for coronary artery disease is an important component in controlling health care expenditures. We conducted a retrospective study to compare the patient charges associated with percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG). All patients underwent treatment for left anterior descending coronary artery stenosis over a 3 year 9 month time period from March 1987 to December 1990 and were followed for 7-58 months (median 43 months) after treatment. The two groups were constructed in such a way that they were balanced for common vessels diseased, number of vessels diseased, sex, age, and ejection fraction (EF). The study included 26 PTCA patients between the ages of 33 and 86 years, 18 males and eight females, with a mean EF of 58 per cent, and 26 CABG patients from 39 to 80 years of age, 18 males and 8 females, with a mean EF of 61 per cent. Charges were categorized as to hospital, professional, cardiac medication, follow-up, and total costs. While CABG was initially more expensive, nine of the PTCA patients (38%) required further interventional treatment (3 PTCA, 5 CABG, 1 PTCA and CABG), whereas none of the CABG patients required further intervention (P < .001). This short-term follow-up demonstrated, that although initially less expensive, repeat interventional charges are significantly higher in PTCA patients. With the escalating costs of health care, the appropriate initial interventional therapy for coronary artery disease must be carefully selected to reduce long-term health care expenses.
