Video-assisted thoracoscopic decortication for management of postpneumonic pleural empyema

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) for decortication or debridement in the management of empyema thoracis has increased the available treatment options but requires validation. We present and evaluate our technique and experience with thoracoscopic management of pleural empyema, irrespective of chronicity. METHODS: From May 1, 2000, to April 30, 2002, VATS debridement and decortication in 70 consecutive patients presenting with pleural space infections was performed with endoscopic shaver system. A retrospective review was performed and the effect of this technique on perioperative outcome was assessed. RESULTS: The VATS evacuation of infected pleural fluid and decortication was successfully performed in 65 of 70 patients. The mean duration of preoperative symptoms before referral was 23 +/- 1.8 days. The mean duration of hospitalization before transfer was 13.5 +/- 1.5 days. Blood loss was 330 +/- 200 mL. Intercostal drainage was required for 5 +/- 3 days. The postoperative hospital stay was 5 +/- 0.7 days. There were no operative mortalities. CONCLUSIONS: Video-assisted thoracoscopic decortication with endoshaver system is a simple and effective method in the management of the fibropurulent or organic pleural empyema.     

Surgical strategy of complex empyema thoracis.

BACKGROUND: The optimal treatment of empyema thoracis has been widely debated. Proponents of pleural drainage alone, drainage plus fibrinolytic therapy, video-assisted thoracoscopic surgical (VATS) debridement, and open thoracotomy each champion the efficacy of their approach. METHODS: This study examines treatment of complex empyema thoracis between June 1, 1994, and April 30, 1997. Twenty-one men and 9 women underwent 30 drainage/decortication procedures (14 open thoracotomies and 16 VATS) in treatment of their disease. Effusion etiology was distributed as follows: infectious-14; neoplastic-associated-7; traumatic-3; other-6. RESULTS: The mean preoperative hospital stay was 14 +/- 8.8 days, (11.4 +/- 6.5 days for VATS vs 16.8 +/- 10.2 days for thoracotomy). Hospital stay from operation to discharge for thoracotomy patients was 10.0 -/+ 7.2 days (median 8.5 days) and for VATS patients 17.6 -/+ 16.8 days (median 11 days). These differences were not statistically significant. Duration of postoperative thoracostomy tube drainage was 8.3 -/+ 4.6 days for thoracotomy patients and 4.7 -/+ 2.8 days in the VATS group (p = 0.01). Operative time for the thoracotomy group was 125.0 -/+ 71.7 minutes, while the VATS group time was only 76.2 -/+ 30.7 minutes. Estimated blood loss for the thoracotomy group was 313.9 -/+ 254.0 milliliters and for the VATS group 131.6 -/+ 77.3 milliliters. Three of the 30 patients (10.0%) required prolonged ventilator support (>24 hours). Morbidity included one diaphragmatic laceration (VATS group) and one thoracic duct laceration (thoracotomy). Two VATS procedures (6.7%) required conversion to open thoracotomy for thorough decortication. CONCLUSIONS: The surgical approach to empyema thoracis is evolving. In the absence of comorbid factors, the significantly lower requirement for chest tube drainage time in the VATS patients suggests that this modality is an attractive alternative to thoracotomy in the treatment of complex empyema thoracis.     

Video-assisted thoracoscopic surgery for children with stage II empyema

Children with stage II empyema often fail traditional medical management, frequently succumbing to the effective albeit morbid clutches of thoracotomy. Video-assisted thoracoscopic surgery (VATS) has been recently introduced as a viable and potentially less morbid alternative to open thoracotomy. We review our VATS experience in children with empyema, assessing surgical outcome. Between August 1996 and March 1999, 13 patients at our institution with stage II empyema that did not respond to conventional medical management underwent a modified VATS with decortication. Data from retrospective chart review reflects intraoperative findings and postoperative course, including average time to defervescence, removal of thoracostomy tube, and hospital discharge. VATS was completed in all 13 patients. All intraoperative cultures of pleural fluid and fibrinopurulent debris obtained at VATS showed no growth. The average time to defervescence was 2.2 days (range, 0-4 days) and to removal of thoracostomy tube 3.6 days (range, 2-5 days). Average total chest tube days in patients with pre-VATS thoracostomy (n = 6) was 14.5 days (range, 8-37 days) versus 3.1 days (range, 2-5 days) in patients (n = 7) who underwent primary VATS (t test, p < 0.05). The average time to surgical discharge after VATS was 5.8 days (range, 3 to 19 days). All patients were well on follow-up clinic visits without delayed complications. VATS can be performed safely and effectively in children with stage II empyema, thus avoiding the morbidity of open thoracotomy and decortication. Importantly, early application of VATS significantly relieves patients of unnecessary days of thoracostomy drainage.     

Continuous pleural lavage may decrease postoperative morbidity in patients undergoing thoracotomy for stage 2 thoracic empyema.

OBJECTIVE: To assess the impact of postoperative continuous pleural lavage (PCPL) after thoracotomy for the treatment of stage 2 pleural empyema in relation to postoperative length of stay and morbidity. METHODS: Stage 2 pleural empyema was diagnosed with computer tomography. Conservative treatment including antibiotics and pleural aspiration was introduced. 89 patients treated for stage 2 pleural empyema by thoracotomy, pleural discharge evacuation and irrigation after pleural decortication were identified after unsuccessful conservative treatment for 10 days. Whenever pleural discharge remained opaque after operation, PCPL was administered daily through the cranial chest tube and discharge evacuated through the caudal pleural suction (10-15 mmHg) tube. Risk factors related to pleural pus and patient outcome were sought for. RESULTS: Seventy-seven out of 89 patients (86.5%) had clear empyema discharge immediately after pleural decortication and irrigation. Pleural discharge remained opaque despite surgery in 12 out of 89 patients (13.5%) and PCPL was introduced. Presence of a combination of risk factors for pleural empyema, such as dental caries, alcohol abuse or previous inflammatory reaction, was predictive for persistence of opaque pleural discharge after operation (P<0.05). Need for re-thoracotomies (in 11 cases, P=ns) and postoperative deaths (P<0.05) were related with patients who did not have PCPL. The length of the hospital treatment was 20.1+/-3.1 (days+/-SEM) among patients with PCPL and 19.2+/-1.8 without PCPL before possible re-thoracotomy, respectively (P=ns). CONCLUSIONS: Early postoperative (1 day-11 months) mortality was statistically associated with patients having fibrinopurulent empyema but no PCPL. PCPL is a feasible method to clear pleural pus discharge without prolongation of hospitalization and may be recommended after thoracotomy for patients with fibrinopurulent stage 2 empyema.     

Experiences in stage-adapted therapy of pleural empyema]

INTRODUCTION: Up till now the phases adapted treatment of a pleural empyema unfortunately is still not obvious, but recently the operative spectrum has been widened in the field of video-assisted thoracoscopic surgery (VATS) of the pleural empyema. PATIENTS AND METHODS: In the present study we examined all our patients with a pleural empyema and we followed them for a postoperative period of 4 years analysing our therapy-efficacy and our treatment concept of pleural empyema. RESULTS: 52 out of 102 patients--who suffered from a pleural empyema in the last 10 years--were reexamined postoperatively. In 96% of the 102 cases we found a phase II-III empyema. Initially all patients were treated with a closed-chest-tube drainage, followed by an operation in 78%. In 6 cases a video-assisted-thoracoscopic evacuation of the cavity with an early decortication was performed. All the 52 patients who were treated in an early phase showed the best functional results 4 years later. CONCLUSION: Especially in phase III the open operative revision of a pleural empyema is the method of choice. In the fibrinopurulent phase the drainage therapy may be sufficient. If the empyema cavity is divided we recommend the early video-assisted-thoracoscopic revision of the thoracic empyema.     

Video-thoracoscopic and open surgical management of thoracic empyema

PURPOSE: To evaluate the outcomes of video-thoracoscopic and open surgical management of patients with thoracic empyema. METHODS: We studied 122 patients retrospectively who underwent surgery for thoracic empyema in our hospital between January, 1999 and January, 2005. Patients' medical records, surgical procedures, and outcomes were reviewed. The study identified 97 affected men and 25 affected women with a mean age of 54 years (range 16-78 years). The empyema was parapneumonic in 95 patients (78%). RESULTS: Forty-four patients who had stage II empyema underwent video-assisted thoracic surgery (VATS). The procedure was converted to thoracotomy in 13 patients (29.5%); the morbidity and mortality rates of VATS were 13% and 0, respectively. Seventy-eight patients had stage III empyema and, along with those 13 who were converted, underwent thoracotomy for decortication. The associated morbidity rate was 12%, and the mortality rate was 6.6%. Thoracotomy was considered successful in 90 of 91 patients (99%); one patient needed a reoperative thoracotomy for an organ space/surgical site infection with pus in the pleural cavity. CONCLUSIONS: Many treatment modalities are available for thoracic empyema, depending on the results of appropriate clinical and laboratory investigations. In fibrinopurulent empyema, VATS debridement is safe and effective, with minimal morbidity and no deaths. Lung decortication via thoracotomy is the only option for organized empyema and is associated with a substantial mortality rate.     

Comparative analysis of chest tube thoracostomy and video-assisted thoracoscopic surgery in empyema and parapneumonic effusion associated with pneumonia in children

BACKGROUND: Controversy exists regarding the optimal management strategy for children having empyema or parapneumonic effusion as a complication of pneumonia. We hypothesized that video-assisted thoracoscopic surgery (VATS)-assisted drainage of pleural fluid and debridement of the pleural space is superior to a chest tube alone in the management of these patients. We further identified predictive factors-namely, presentation, radiographic findings, antibiotic usage, and pleural fluid features-that could predict the need for VATS rather than primary chest tube drainage. METHODS: Forty-nine pediatric patients with pneumonia complicated by parapneumonic effusion or empyema treated at the Children's Hospital of Pittsburgh (1997-2003) were divided into three groups according to the therapy instituted: Primary chest tube, chest tube followed by VATS, or primary VATS. The groups were analyzed in terms of demographics and outcome, as judged by pleural fluid analysis and hospital resource utilization. Demographic and outcome data were compared among groups using one-way analysis of variance and the Student t-test. RESULTS: All groups were similar with respect to demographics and initial antibiotic usage. Patients undergoing primary VATS had a higher initial temperature, whereas radiographic findings of mediastinal shift and air bronchograms were more likely to be found in patients who underwent primary chest tube placement. Patients undergoing primary VATS demonstrated a significantly shorter total stay and lower hospital charges than the other groups. Forty percent of children started on chest tube therapy failed even with subsequent VATS, necessitating a significantly longer hospital course (18 +/- 3 vs. 11 +/- 0.8 days; p < 0.05) and higher hospital charges ($50,000 +/- 7,000 vs. $29,000 +/- 1000) than those having primary VATS. CONCLUSIONS: Patients treated by primary VATS had a shorter stay and lower hospital charges than patients treated by chest tube and antibiotic therapy alone. There were no demographic, physiologic, laboratory, or chest radiographic data that predicted the selection of VATS as an initial treatment. These data suggest a strategy of primary VATS as first-line treatment in the management of empyema or parapneumonic effusion as a complication of pneumonia in pediatric patients.     

Benefits of early aggressive management of empyema thoracis

BACKGROUND: The end-target of the management of thoracic empyema is to obtain early rehabilitation by re-expansion of the trapped lung resulting from intrapleural infected material. Our aim was to shorten the hospitalization time and to prevent a possible thoracotomy by using video-assisted thoracoscopy initially. METHODS: Seventy patients with parapneumonic empyema were prospectively studied between January 1997 and June 2004. The patients were randomly divided into two groups. In group I (n = 35 patients), a chest tube was inserted into the patients after pleural content was evacuated and fibrins were debrided using video-assisted thoracoscopy. In group II (n = 35 patients), tube thoracostomy was carried out without using a video-assisted thoracoscope. Both groups were compared in terms of hospitalization time, open surgery for decortication and complications. RESULTS: There was no statistically significant difference between the groups from the point of view of age and sex (P > 0.05). In group I, 17.1% of the patients underwent open decortication, whereas in group II, 37.1% of the patients underwent the same procedure (P < 0.05). Whereas average hospital stay in group I was 8.3 days (range, 7-11 days), it was 12.8 days in group II (range, 10-18 days; P < 0.05). There was one bronchopleural fistula in group I, and there was one bronchopleural fistula and one death in group II. CONCLUSION: Video-assisted thoracoscopic evacuation and chest tube insertion in situ is a new therapeutic approach for pleural empyema that shortens hospital stay and reduces the necessity of open decortication.     

Outcomes of Video-Assisted Thoracic Surgical Decortication in 274 Patients with Tuberculous Empyema

Objective: The present work aimed to retrospectively assess the outcomes associated with decortication by video-assisted thoracic surgery (VATS) in patients with tuberculous empyema.Methods: Patients (n = 274) who underwent decortication by VATS for surgical management of pleural empyema between January 2000 to 2010 were included. Pre-, intra-, and post-operative characteristics were observed for all patients, which were followed up for 12 months to evaluate surgical outcomes such as postoperative complications and disease recurrence.Results: No patients required conversion to thoracotomy, and no death or postoperative bleeding was reported. The mean operation time was 104.5 ± 20.4 min, with 271.5 ± 41.3 ml intraoperative blood loss and median length of hospital stay of 7.2 ± 3.4 days. Of the 274 patients, 262 were followed up for 12 months; 26 (9.9%) patients showed complications, including incomplete lung re-expansion (11 patients) and persistent air leak (6 patients). While early disease recurrence was observed in 3 (1.1%) patients after surgery, late recurrence was reported for 6 (2.3%) individuals. Interestingly, the complication rate was much higher in patients with chronic empyema (15/34, 44.1%) than in subjects with acute empyema (11/228, 4.8%).Conclusions: Decortication by VATS decreases postsurgical complications, and results in decreased disease recurrence. This study demonstrated improved outcomes by decortication by VATS, even in patients with stage III tuberculous empyema.     

Surgical treatment of pleural empyema--changing priorities

The surgical management of pleural empyema and post-traumatic clotted haemothorax is described. The study included 15 cases of post-thoracotomy empyema, 23 of empyema of other aetiology and five of post-traumatic haemothorax. Chest-tube drainage was the first measure in most cases. Post-pneumonectomy empyema was treated with partial thoracoplasty plus omentoplasty (8 cases) or plus myoplasty (1 case). Empyema after lobectomy or bilobectomy (4 cases) or after failed decortication (1 case) was managed with thoracoplasty or, in cases of concomitant wound infection, with open-window thoracostomy followed by thoracoplasty. Empyema after subclavian artery reconstruction (1 case) was cleared by removal of a previously unrecognized foreign body. For early empyema of other aetiology or haemothorax (10 cases in total), treatment comprised debridement by video-assisted thoracoscopic surgery (VATS). VATS was also used to establish suitable pleural drainage prior to elective thoracotomy (2 cases). Decortication and partial parietal pleurectomy were performed for organizing-stage empyema (16 cases). Three of the 15 patients with post-thoracotomy empyema died perioperatively, one died two months postoperatively and one had recurrence of bronchopleural fistula during follow-up. One patient with VATS debridement subsequently required thoracotomy and lobectomy for lung abscess. All the others with VATS or decortication recovered without complications. During follow-up there was no mortality or recurrence of empyema.     

Primary thoracoscopic treatment of empyema in children

OBJECTIVE: The optimal treatment of pediatric empyema remains controversial. The objective of this study is to compare the use of conventional management versus primary thoracoscopic drainage and decortication in children with empyema. METHODS: Conventional management has consisted of chest drain insertion under general anesthesia plus intravenous antibiotics. Thoracoscopic drainage and decortication has consisted of primary thoracoscopic drainage and decortication plus antibiotics. The clinical course of 54 patients treated conventionally between 1989 and 1997 was compared with that of 21 patients treated by means of thoracoscopic drainage and decortication between September 2000 and September 2001. RESULTS: Results of the study demonstrated that patients in the drainage-decortication group had fewer invasive interventions per patient than those in the conventional management group (1.0 vs 1.26). Patients undergoing thoracoscopic drainage and decortication also had significantly shorter durations of intravenous antibiotic therapy (7.6 +/- 1.2 vs 18.2 +/- 7.5 days), chest tube drainage (4.0 +/- 0.5 vs 10.2 +/- 6.1 days), and hospital stays (7.4 +/- 0.8 vs 15.4 +/- 7.4). Moreover, there were no open thoracotomies and decortications in the thoracoscopic drainage and decortication group, whereas in the conventional management group 39% (21/54) of patients underwent an open procedure. CONCLUSION: Although the 2 groups were not prospectively randomized and they were treated in different time periods, the results of this study support the use of thoracoscopic surgery as the primary therapeutic modality in children presenting with pleural empyema. This strategy appears to offer significant benefits over conventional treatment in terms of duration of treatment and the need for more invasive surgery.     

Complications following blunt and penetrating injuries in 216 victims of chest trauma requiring tube thoracostomy

Tube thoracostomy (TT) is required in the treatment of many blunt and penetrating injuries of the chest. In addition to complications from the injuries, TT may contribute to morbidity by introducing microorganisms into the pleural space or by incomplete lung expansion and evacuation of pleural blood. We have attempted to assess the impact of TT following penetrating and blunt thoracic trauma by examining a consecutive series of 216 patients seen at two urban trauma centers with such injuries who required TT over a 30-month period. Ninety-four patients suffered blunt chest trauma; 122 patients were victims of penetrating wounds. Patients with blunt injuries had longer ventilator requirements (12.6 +/- 14 days vs. 3.7 +/- 7.1 days, p = 0.003), longer intensive care stays (12.2 +/- 12.5 days vs. 4.1 +/- 7.5 days, p = 0.001), and longer periods of TT, (6.5 +/- 4.9 days vs. 5.2 +/- 4.5 days, p = 0.018). Empyema occurred in six patients (3%). Residual hemothorax was found in 39 patients (18%), seven of whom required decortication. Recurrent pneumothorax developed in 51 patients (24%) and ten required repeat TT. Complications occurred in 78 patients (36%). Patients with blunt trauma experienced more complications (44%) than those with penetrating wounds (30%) (p = 0.04). However, only seven of 13 patients developing empyema or requiring decortication had blunt trauma. Despite longer requirements for mechanical ventilation, intensive care, and intubation, victims of blunt trauma seemed to have effective drainage of their pleural space by TT without increased risk of infectious complications.     

Video thoracoscopic treatment in pleural empyema

BACKGROUND: To evaluate the possible role and the effectiveness of videothoracoscopy (VATS) in the treatment of pleural empyema. METHODS: Personal experience on 40 cases of pleural empyema treated by (VATS) during 5 years is reported. The underlying diseases were: pneumonia (32), pneumothorax (3), tuberculosis (2), abdominal diseases (2) and lung cancer (1). Before VATS at least one thoracentesis was performed to evaluate the characteristic of the pleural fluid. RESULTS: Due to complications related to thick pleural adhesions, in one case (2.5%) the procedure was converted to open surgery, while in the remaining 39 cases VATS was able to achieve a complete cleaning of the pleural space with re-expansion of the pulmonary parenchyma. The improvement of the clinical symptoms were observed after a mean period of 3.5 days (range: 1-12 days). Chest tube was removed in a mean period of 4.8 days (range: 3-11 days); five patients had prolonged air leak from 6 to 10 days after surgery. CONCLUSIONS: In conclusion we are of the opinion that VATS has to be considered a very important mean for the treatment of pleural empyema; its use in the fibrinopurulent phase of the disease should give very good results, while in the following phase its indications are controversial.

Chronic postpneumonic pleural empyema: comparative merits of thoracoscopic versus open decortication

Objective: We seek to evaluate the comparative merits of thoracoscopic versus open decortication in the surgical management of patients with chronic postpneumonic pleural empyema. Methods: From January 1996 to December 2006, 308 patients (180 males, 128 females, mean age: 56.3 years, range: 17–82 years) with chronic postpneumonic pleural empyema underwent decortication after failure of conservative treatment. Results: Decortication was performed by open thoracotomy in 123 (39.9%) patients (OT) and by videothoracoscopy (VT) in 185 (60.1%). Mortality was 1.29% (4/308). Morbidity was 21.1% (65/308). At 6 months follow-up, three VT patients showed recurrent empyema and underwent re-do surgery by video-assisted-thoracoscopy (VATS) (one patient) or by thoracotomy (two patients). The videothoracoscopic approach showed statistically significant better results in terms of in-hospital postoperative (day 1 and day 7), pain (p < 0.0001), postoperative air leak (p = 0.004), operative time (p < 0.0001), hospital stay (p = 0.020) and time to return to work (p < 0.0001). The analysis of postoperative pain at 6 months follow-up showed no significant differences among the different groups. Conclusions: In the light of our experience, videothoracoscopic decortication appears to be the surgical treatment of choice for chronic postpneumonic pleural empyema even if a multicentric-randomised trial should be performed before videothoracoscopic decortication becomes the gold standard for the treatment of pleural empyema.     

Usefulness of thoracoscopic surgery in the diagnosis and management of thoracic diseases

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) has been recently utilised in the diagnosis and management of thoracic diseases. In this article we report our series of patients with established indications for VATS treatment. METHODS: Over the past 6 years we performed 104 VATS procedures for diagnostic and therapeutic purposes in 95 men and 39 women. The specific indications for VATS were: lung biopsy for undiagnosed diffuse lung disease, mediastinal biopsy and cysts, pleural effusion, empyema, pneumothorax and bullous lung disease, pericardial effusion and cyst, parvertebral abscess and solitary pulmonary nodules. RESULTS: There was no operative mortality. Postoperative non-fatal complications were seen in 7 cases. The overall median duration of chest tube drainage was 2.5 days and the mean postoperative stay 3 days. In diffuse lung disease a tissue diagnosis was obtained in all cases. Definitive diagnosis in the patients with undiagnosed pleural effusion was obtained in 90% of cases and the overall diagnostic rate was 98.5%. The success rate of the empyema (stage II) treatment and the therapeutic procedures is 100% after a mean follow-up of 12 months (range 6-30). Conversion to thoracotomy was needed in 6 cases. In all patients the postoperative pain was controlled with intake of non-narcotic analgesics with satisfactory results. CONCLUSIONS: VATS is worth considering and has been established as procedure of choice, with exceptional results in various chest diseases such as undiagnosed pleural effusions, recurrent, post-traumatic or complicated spontaneous pneumothorax, stage II empyema, accurate staging for lung cancer in the resection of peripheral solitary pulmonary nodule less than 3 cm, and lung biopsy for pulmonary diffuse disease.     

THORACOSCOPIC MANAGEMENT OF PLEURAL EFFUSIONS REVISITED

Pleural effusion is a commonly encountered clinical condition. We report our experience with video assisted thoracoscopic surgery (VATS) in the management of pleural effusions in three groups of patients: (1) Patients with cryptogenic pleural effusions for diagnosis; (2) patients with established malignant effusions for talc insufflation and limited decortication; and (3) patients with early empyema for debridement and drainage. From September 1992 to March 1994, we have successfully managed 28 patients with pleural effusions (12 males, 16 females; age ranged from 22 days to 73 years). Management consisted of 16 diagnostic thoracoscopies with guided pleural biopsies, seven limited decortications for trapped lungs, 12 talc insufflation for recurrent symptomatic malignant effusions and debridement and drainage of tive empyemata. There was no mortality or intra-operative complications. The procedure was tolerated well by all patients. The mean duration of chest drainage and hospital stay were I.2 and 2.8 days for group 1 patients, 4.5 and 6.4 days for group 2, and 5.6 and 7.1 days for group 3. Specitic histological diagnosis was obtained in all but two patients (88%). Thoracoscopic talc insufflation was successful in 92% of cases at mean follow up of 8 months. Thoracoscopic debridement and drainage of empyema resulted in rapid resolution of sepsis in all cases. Advances in video camera technology and instrumentation have allowed more therapeutic manoeuvres to be carried out. We conclude that VATS is a safe and effective way of managing selected patients with pleural effusions.     

Decortication in paediatric empyema, comparative study of early vs late intervention

Background

A retrospective study was conducted at Govt Medical College, Jammu in the pediatric patients who were referred to Cardio Thoracic and Vascular Surgery department with thoracic empyema and were taken up for thoracotomy and decortication Our experience showed that early intervention gave better results than in group with delayed intervention.

Material and methods

Between January 2003 and 2011, 76 patients underwent pleural decortication in pediatric age group presenting with thoracic empyema who did not respond to conservative management. 45 patients were male and 31 patients were female. They were initially evaluated with routine chest radio graphs and with Computed Tomography (CT) chest. Diagnosis of thoracic empyema was made in these cases with radio graphic evidence and was substantiated with pleural fluid cultures 62 underwent early intervention whereas 14 had delayed intervention.

Results

62 (84 %) patients underwent early decortication (within 4 weeks of Intercostaltube insertion) whereas 14 (16 %) cases were taken up for delayed decortication beyond 1 month due to unavoidable reasons like delayed referral, high grade fever or because of other co morbid diseases. In early group all patients responded well to early decortications. 6 (10 %) patients required secondary intervention that included 4 (6.4 %) patients due to recurrence of empyema or lung collapse after surgery & 2(3.2 %) patients required lung resection. and the mean hospital stay was 12 days In late intervention group, it was found that the operative time increased, the duration of chest drain also increased due to air leak/increased drainage leading to increased hospital stay (16 days) and 6 (42 %) patients required secondary intervention.

Conclusion

Early decortication is an effective surgical treatment for thoracic empyema as It facilitates early evacuation and mechanical decortication of pleural space with no additional morbidity and leads to reduced time for chest tube drainage and shortens hospital stay.     

Stage-adapted therapy of pleural empyema. Results during 1992-1998

Despite the decreasing number of patients suffering tuberculosis and the use of modern broad spectrum antibiotics the pleural empyema did not lose its relevance. The main reasons are increasing numbers of patients with drug and alcohol abuse or immunodeficiency of different causes. We retrospectively analysed the data of 73 patients treated of pleural empyema between 1992 and 1998. Considering the known stages of pleural empyema we present the corresponding therapeutic results. All patients classified as stage I were treated with a chest drain and cure was achieved in all of them (100%). The treatment for patients classified as stage II was different: 5 out of 32 were treated with a continuous irrigation and suction chest drain system. 18 patients first underwent thoracoscopy and were afterwards treated with a continuous irrigation and suction system. Another 9 patients primarily underwent an early open decortication. In 40% the treatment with the suction and irrigation system was successful. Using video-assisted thoracoscopy (VATS) cure was achieved in 94.4%, with open decortication in 100%. The preferred treatment of patients classified as stage III is the open decortication. After the first operation 80% (30 patients) were cured. 6 patients needed thoracoplastic procedures after the first intervention. No patient was discharged neither with a permanent chest drain nor a permanent thoracic window. With the results a cause dependent analysis of morbidity and mortality was done. The overall morbidity rate was 27.9% and the overall mortality 5.4%. The treatment of pleural empyema still remains to be problematic. Corresponding to our results pleural empyema classified as stage I is best treated with a simple chest tube. The video-assisted thoracoscopy (VATS) lacks of complications and is a very efficient method in treating stage II. The method of choice in stage III is the open decortication which in the case of a chronic and recurrent or persistent infection should be followed by a thoracoplastic procedure.     

Current surgical treatment of thoracic empyema in adults.

A review of the recent literature on treatment modalities of adult thoracic empyema was conducted in order to expose the controversies and verify where consensus exists. Critical reading filtered through clinical experience was the method followed. The roles of surgical drainage, lavage techniques, debridement via VATS, decortication, thoracoplasty and open window thoracostomy were considered using the Oxford Center of Evidence Based Medicine criteria. The roles of the different therapeutical modalities were interpreted in the light of the triphasic nature of empyema thoracis. The randomised controlled trials came up with conflicting results. With two exceptions all of the papers reviewed provide level (2b) or below evidences. The lack of a single ideal treatment modality or policy reflects the complexity of the diagnosis and staging of this heterogeneous disease. Basic elements of intervention--drainage, different evacuation techniques, decortication, thoracoplasty and open window thoracostomy--are well-established technical modalities; however, neither a universally acceptable primary modality nor the gold standard of their sequence is available. Drainage remains to be the initial treatment modality in Phase I disease. Debridement via VATS is a safe, reliable and efficient method in the fibrinopurulent phase. Organised pleural callus requires formal decortication. Open window thoracostomy is a simple and safe procedure for high-risk patients and results in quick detoxication. Thoracoplasty kept its final role in pleural space management. Acute postoperative bronchial stump insufficiency requires immediate surgery. Evacuation of toxic material is mandatory. No single-stage procedure offers a solution. An optimised agressivity treatment modality should be tailored to the condition of the patient and to the potential of the persisting cavity. Decision-making involves a triad consisting of the aetiology of empyema (i.e. primary vs secondary), general condition of the patient and stage of disease, while considering the triphasic nature of development of thoracic empyema. The current attitudes show that the present concepts are based mainly on expert opinion. Flexibility and patience on behalf of the surgeon and nursing staff, the patient and the hospital management, as well as a good understanding of the complexity of this condition are the cornerstones of the treatment. No exclusive sequence of procedures leading to a uniformly predictable successful outcome is available. Individualised approaches can be recommended based on institutional practice and local protocols. Thoracic empyema in general seems to remain resilient to fit completely into the categories of evidence-based medical approach.
