[Clinical features and surgical treatment of thoracic Castleman's disease]

OBJECTIVE

To explore the clinical features and surgical treatment of thoracic Castleman's disease.

METHODS

The clinical symptoms, pathological, laboratory, CT findings and results of surgery in 32 patients with Castleman's disease from June 1996 to November 2008 were evaluated. Among the 32 patients, there were 14 male and 18 female, aged from 16 to 48 years old with a mean age of 34.2 years old. Thirteen cases had symptoms including short of breath, irritable cough, or chest pain, while 14 cases had no symptoms. Mediastinal or hilar tumors were found by CT examination.

RESULTS

Tumor was surgically removed in all the 32 patients except one died with anesthetic accident. Castleman's disease was conformed by pathology. Five cases were diagnosed as with paraneoplastic pemphigus, 3 of them were attacked by bronchiolitis obliterans. All 5 cases were failed by the use of prednisone. The signs of PNP were dissolved after operation, but pulmonary lesions failed to improve. There was no recurrence in all cases.

CONCLUSIONS

PNP and lung abnormalities are the rare and severe complications of thoracic Castleman's disease. Surgical resection of the tumor is the first choice for treatment.

Management of complicated giant thoracic hydatid disease

BACKGROUND

Hydatid disease is a parasitic infestation frequently seen in sheep- and cattle-raising areas of the world, and has been known since the time of Galen and Hippocrates. We retrospectively evaluated patients who underwent surgery in our department due to complicated giant intrathoracic hydatid cysts.

MATERIAL/METHODS

Twenty patients with complicated giant intrathoracic hydatid cysts were operated on between May 2001 and May 2007 in our department. There were 14 male and 6 female patients, with an age range from 10 to 47 years (mean 23.7+/-11.2 years).

RESULTS

The most common symptoms were cough, chest pain, fever, and dyspnea. The most common physical finding was decreased breathing sounds at the affected hemi-thorax. There were signs of cyst perforation of the bronchial space in 14 patients. The cysts were ruptured to the pleural space in 5 patients, with pleural effusion or localized empyema; 4 of them required decortication due to air trapping in the lung. The cyst was found to be intact but infected in 1 patient with cardiac cyst. Cystotomy plus capitonnage was the most frequently used surgical procedure, which was performed in 18 patients, while lobectomy was performed in 1 patient, and left ventriculotomy plus cystotomy plus capitonnage was performed in 1 patient.

CONCLUSIONS

All thoracic hydatid cysts should be operated on as soon as they are diagnosed in order to avoid complications, and surgery should be as conservative as possible. Since preoperative medical therapy can lead to perforation, additional adjuvant medical therapy should only be administered postoperatively to avoid recurrences.

[Hydatid cyst of the chest wall mimicking metastatic colon cancer]

Chest wall hydatidosis, rare even in the endemic countries, represents 0.09 to 0.3 % of all cases of thoracic echinococcosis. The authors report the case of a 76 year-old man presenting a chest wall mass 4 years after surgery for colic carcinoma. The mass presented both hypoechoic and hyperechoic structures in the ultrasound chest echography. Therefore, metastastic colon cancer was suspected. The pathological study of the mass revealed hydatid membranes. Thoracic tomodensitometry supported the diagnosis of costovertebral and soft tissue hydatid cysts. The patient underwent the surgical resection of two rib arches, a transverse apophysis and the neighbouring soft tissue associated with pre- and post-surgical albendazole. No clinical manifestations were noted in the follow-up after 1 year.

Combined reconstruction of complex defects of the chest wall

Defects of the chest wall are often encountered, and good results can be obtained both cosmetically and functionally from their treatment. We treated 13 patients with full thickness chest wall defects. Follow up ranged from 12 days to 19 months. Three had had recurrent breast carcinoma, seven relapse after excision of a sarcoma, two had had lesions of the chest wall after irradiation, and one had a sternal fistula. Local skin, musculocutaneous and free latissimus dorsi and anterolateral thigh flaps were done to cover soft tissue. Fascia lata, polypropylene (Marlex) mesh, and Marlex mesh-methylmethacrylate sandwich prosthesis, were used to stabilise the skeleton in nine patients. Two of the patients died postoperatively, one early. The use of Marlex mesh-methylmethacrylate sandwich prostheses for the stabilisation of the skeleton and local musculocutaneous flaps for covering soft tissues after resection of three or more ribs is effective.

[Miniinvasive video-assisted accesses in thoracic surgery]

Personal 10-year experience of 2412 operations on the thorax is summarized. 1394 (57,8%) of interventions were performed videothoracoscopically. Technical aspects of gross videothoracoscopic operations (552 lung resections and 162 pneumonectomies), indications for the use of the method are discussed. Own results are supplemented with meta-analysis of the literature.

Independent predictors for early and midterm mortality after thoracic surgery

BACKGROUND

The purpose of the present study was to determine independent predictors for early and midterm mortality for the whole context of thoracic surgery.

METHODS

We studied 1453 consecutive patients who underwent thoracic surgery between 2002 and 2005. Operations included lung resections (n = 504), mediastinal (n = 468), pleural and pericardial (n = 226), esophageal (n = 83), chest wall (n = 85), tracheal (n = 50) and other procedures (n = 37). Midterm survival data (mean follow-up 2.0 +/- 1.1 years) were obtained from the National Death Index. Multivariate logistic regression was used to assess in-hospital mortality. Independent predictors for midterm mortality were determined by multivariate Cox regression analysis.

RESULTS

There were 47 (3.2 %) in-hospital and 312 (21.5 %) late deaths. Independent predictors for in-hospital mortality included Zubrod score (OR 2.72, P < 0.001), ASA score (OR 3.42, P < 0.001), pneumonectomy (OR 20.71, P = 0.001) and no history of cerebrovascular events (OR 0.27, P = 0.011). Independent predictors for midterm mortality included age (HR 1.03, P < 0.001), weight loss (HR 1.57, P = 0.005), Zubrod score (HR 1.47, P < 0.001), primary lung cancer (HR 1.98 P < 0.001), intrathoracic extrapulmonary metastases (HR 2.78, P < 0.001), primary chest wall tumor (HR 0.14, P = 0.008), diabetes requiring insulin (HR 1.71, P = 0.017), no preoperative renal failure (HR 0.57, P = 0.004), no comorbidities (HR 0.54, P = 0.009), ASA score (HR 1.69, P < 0.001), postoperative radiation treatment (HR 1.90, P = 0.016), pneumonectomy (HR 2.18, P = 0.040), reoperation for bleeding and/or postoperative transfusion (HR 3.10, P = 0.027) and postoperative pulmonary complications (HR 1.89, P = 0.013).

CONCLUSIONS

We determined independent predictors for in-hospital and midterm mortality for the whole context of thoracic surgery. Zubrod and ASA scores affect both early and midterm mortality.

[Videothoracoscopic removal of ectopic liver]

Authors present a case of an ectopic liver in the chest of a 14 year-old female patient. The lesion was discovered by screening chest X-ray and was consequently removed by videothoracoscopic surgery. A brief literature review was carried out, too.

Ex utero intrapartum treatment (EXIT), a resuscitation option for intra-thoracic foetal pathologies

The ex utero intrapartum treatment (EXIT) procedure is designed to guarantee sufficient oxygenation for a foetus at risk of airway obstruction. This is achieved by improving lung ventilation, usually by establishing an airway during caesarean delivery whilst preserving the foetal-placental circulation temporarily. Indications for the EXIT procedure have extended from its original use in reversing iatrogenic tracheal obstruction in congenital diaphragmatic hernia to naturally occurring upper airway obstructions. We report our experience with a new and rarely mentioned indication for the EXIT procedure, intra-thoracic volume expansions. The elaboration of lowest risk scenarios through balancing risks with alternative options, foetal or neonatal intervention and coordination between professionals from various disciplines are the most important conditions for a successful EXIT procedure. The EXIT procedure requires a caesarean section that specifically differs from the traditional caesarean section during which uterine tone is maintained to minimize maternal bleeding. To guarantee foetal oxygenation during the EXIT procedure, profound uterine relaxation is desired. To gain time with optimal placental oxygenation in order to safely perform an airway intervention in a baby at risk of hypoxia may require deep inhalation anaesthesia and/or tocolytic agents. We review the EXIT procedure and present a case series from the University Hospital of Geneva that contrasts with the common indication for the EXIT procedure usually based on upper airway obstruction by its exclusive indication for intra-thoracic malformations/diseases.

Catamenial and Noncatamenial, Endometriosis-related or Nonendometriosis-related Pneumothorax Referred for Surgery

RATIONALE

Catamenial and endometriosis-related pneumothorax are considered relatively rare entities. Their clinical characteristics and outcome are incompletely known.

OBJECTIVES

To evaluate the frequencies, clinical characteristics, and outcomes of catamenial and endometriosis-related pneumothoraces occurring in women with no underlying lung disease referred for surgical treatment.

METHODS

Clinical files of all the women of reproductive age referred to our center during a 6-year period for surgical treatment of spontaneous pneumothorax were retrospectively reviewed. Catamenial pneumothorax (CP) was defined as recurrent pneumothorax occurring between the day before and within 72 hours after the onset of menses. All histologic slides were reviewed to confirm initial diagnoses.

MEASUREMENTS AND MAIN RESULTS

A total of 114 women underwent video-assisted thoracic surgery; 28 women (24.6%) had CP (right-sided in all but one), and diaphragmatic abnormalities (perforations and/or nodules) were observed in 22 of them. Diaphragmatic abnormalities were seen in 21 of 86 patients with non-CP. Histologic examination found endometriosis, mainly diaphragmatic, in 18 of 28 CPs and 11 of 86 non-CPs. A 6-month antigonadotropic treatment was prescribed postoperatively to women with either CP or endometriosis-related pneumothorax. Mean follow-up was 32.7 (+/-18.5) months. Recurrence rates in CP, non-CP but endometriosis-related, and non-CP non-endometriosis-related pneumothoraces were 32, 27, and 5.3%, respectively.

CONCLUSIONS

Our experience shows that (1) CP and/or endometriosis-related pneumothoraces account for an important percentage of spontaneous pneumothoraces referred for surgery, (2) diaphragmatic abnormalities seem to play a fundamental role in their pathogenesis, and (3) management is difficult because of the high recurrence rate.

A decade of cardiothoracic surgery at a tertiary care hospital in Karachi, Pakistan

OBJECTIVE

The medical records at Aga Khan University were reviewed to analyze the trends, mortality and patients characteristics of cardiothoracic surgeries in the last decade.

METHOD

The medical records of all adult cardiac, thoracic and combined cardiothoracic operations performed during January 1995 to December 2004 at the Aga Khan University Hospital were reviewed. Data were retrieved and analyzed for trends, patient characteristics, and procedure mortality.

RESULTS

From January 1995 - December 2004, 4553 cases were eligible for the study, of which 73% were males and 9.4% were children. Male to female ratio changed from 1.3:1 to 3:1 from childhood to adulthood. Number of patients requiring cardiothoracic intervention increased continuously throughout the period, cardiac operations outnumbering thoracic or combined procedures. Ten-year average annual mortality remained 4.8% with slight variation per annum. Age distribution of cardiac surgery patients remained the same, however, constantly increasing number of over-70-year olds was observed. Mortality for isolated CABG, isolated valve and CABG with valve remained 1.9%, 4.3% and 18.3% respectively.

CONCLUSION

Trends of cardiothoracic procedures appear similar to those in the developed countries, so are the mortality figures.

Thoracic surgical operations performed under local anesthesia and sedation for diagnosis and treatment

Generally, the operative procedures for the diagnosis or treatment of mediastinal, intrathoracic and/or chest wall lesions requiring rib resection are performed under general anesthesia. Although evidence suggests that thoracoscopy can be performed under local anesthesia, no report has indicated that some major thoracic procedures can be accomplished without general anesthesia. In our study, we advocate that certain surgical procedures could be performed under local anesthesia with a performance similar to that of general anesthesia. Thirty patients underwent thoracic procedures with local anesthesia and sedation for diagnosis and treatment. Seventeen of the patients were men, and the mean age of the patients was 49.6 years (range 16 to 71 years). There were 13 diagnostic procedures, and 17 procedures were for treatment purposes. The operative procedures performed using only local anesthesia were mini-thoracotomy (n = 9), mediastinotomy (n = 4), revision of a full-thickness posterolateral thoracic incision (n = 7), resection of the chondroma (n = 4), Eloesser flap (n = 1), metastasectomy of the chest wall (n = 3), empyectomy (n = 1), and video-assisted thoracoscopy (n = 2). Severity of pain was evaluated by VAS. There were no oral or intravenous analgesic requirements in the early postoperative period. No complications attributable to the procedure were observed. Thoracic surgical procedures for diagnosis and treatment performed under local anesthesia are simple, effective, economical and comfortable for the patient.

Predictors of general complications after video-assisted thoracoscopic surgical procedures

BACKGROUND

The video-assisted thoracoscopic approach has become the preferred method for many procedures due to the reduced trauma, complication rate and morbidity. The aim of this study was a risk evaluation of patients undergoing video-assisted thoracoscopic surgery (VATS) procedures.

METHODS

Between 1991 and 2004, 1,008 patients were included in this single-center retrospective analysis. Risk assessment was performed using univariate and multivariate analysis.

RESULTS

Multivariate analysis revealed that patient age (p = 0.003), the duration of the VATS procedure (p = 0.008), redo-VATS (p < 0.001) and conversion to open thoracotomy (p < 0.001) correlated significantly with the incidence of complications. Patients with immune deficiency following organ transplantation had the highest complication rate at 31.7%, which was significantly higher than for patients with either benign disease (p = 0.010) or malignant disease (p = 0.019).

CONCLUSIONS

VATS is a safe procedure, but extra caution is recommended for patients with a higher risk profile (age, redo-VATS, immune deficiency).

[Clinical characteristics of Bochdalek hernia in neonates and infants]

OBJECTIVE

To summarize the clinical characteristics, diagnosis and treatment of Bochdalek hernia in neonates and infants.

METHODS

The data of 15 neonates and 10 infants with Bochdalek hernia,undergoing the normal diagnosis and surgical repair from August 1983 to June 2004, were retrospectively reviewed. Location was left in 22 cases and right in 3 cases. Twenty-four cases were treated by operation and 1 case died of respiratory failure before operation.

RESULTS

Before April 1998, 7 of 8 (5 neonates, 3 infants) cases of Bochdalek hernia stayed healthy and respiratory symptom-free 1 year after operation; they were followed up 1 year and 3 months to 11 years. One premature neonate with Bochdalek hernia died of respiratory failure before operation, and his lung volume was found to be dysplasia. From April 1998 to June 2004, 15 (8 neonates,7 infants) of 17 (10 neonates, 7 infants)cases of Bochdalek hernia survived postoperatively, while 2 neonates died of respiratory failure.

CONCLUSION

The earlier dyspnoea of neonates of Bochdalek hernia occur, the worse their healthy status appear. The standard and timely surgical repairs could improve the curative ratio. Whether the operation was suspended depended on the healthy states of babies.

Huge extrapleural hematoma in an anticoagulated patient

We report an unusual case of huge extrapleural hematoma in an anticoagulated patient with no apparent traumatic episode. An extrapleural hematoma (EH) was successfully treated by video-assisted thoracic surgery (VATS). If an EH is large enough to cause ventilatory or circulatory disturbances, VATS may be the first option for the management of EH. Otherwise limited thoracotomy should be considered.
