Parenchyma-Preserving Surgery in the Management of Pulmonary Hydatid Cysts

Pulmonary hydatid cysts remain a significant health problem in endemic regions like Turkey. Here, we present our surgical experience in patients with pulmonary hydatid cysts. Between January 1985 and January 2001, 1118 operations were performed in 1032 patients (528 males, 504 females; mean age 32.7 years; range 1–87 years) with pulmonary hydatid cysts in our department. Posterolateral thoracotomy was performed in 1015 (98.3%), two-stage thoracotomy in 34 (3.3%), and median sternotomy in 17 (1.7%) patients. We preferred conservative surgical procedures. As a surgical procedure, cystotomy and capitonnage was performed in 626 (56%), cystotomy alone in 368 (33%), wedge resection in 81 (7%), enucleation in 29 (3%), and decortication in 11 (1%) patients. None of our patients were treated with anatomic resection. During surgery, 949 patients (92%) had unruptured and 83 patients (8%) had ruptured hydatid cyst. The morbidity ratio was 6.7%. Major complications were wound infection (2.3%), prolonged air leak (1.9%), atelectasis (1.2%), pleural effusion (0.8%), postoperative hemothorax (0.6%), and empyema (0.3%). Two patients (0.2%) died within the first month postoperatively. Mean follow-up was 31.2 months. Recurrence was detected in only 35 patients (3.3%). Treatment of pulmonary hydatid cyst is primarily surgical. Medical treatment is indicated for recurrent and multiple hydatid cysts postoperatively. Cystotomy alone, or cystotomy and capitonnage, as parenchyma-preserving surgery, is preferred. Radical surgery including pneumonectomy, lobectomy, and segmentectomy should be avoided.

Management of Recurrent Malignant Pleural Effusion with Chemical Pleurodesis

PurposeMalignant pleural effusion is a common complication of primary and metastatic pleural malignancies. It is usually managed by drainage and pleurodesis, but there is no consensus as to the best method of pleurodesis. We compared the effectiveness, side effects, and cost of different chemical pleurodesis agents used in patients with malignant pleural effusion.MethodsBetween January 1990 and December 2001, 108 patients with malignant pleural effusion underwent chemical pleurodesis in our department. Thoracoscopy was performed in 64 patients (59%), a minithoracotomy in 18 (17%), tube thoracostomy in 11 (10%), and a small-bore catheter was inserted in 15 (14%). Talc was used in 68 (63%) patients, tetracycline in 26 (24%), and bleomycin in 14 (13%). Talc was instilled by insufflation during surgery after drainage, whereas tetracycline and bleomycin were instilled via tube or catheter for pleural analgesia.ResultsTalc resulted in significantly earlier tube and catheter removal, after an average 4.1 days versus 5.1 days after tetracyline, and 6.3 days after bleomycin (P = 0.026, P = 0.001, respectively). A significantly lower reaccumulation ratio in 90 days was achieved by the talc group, with nine (13.2%) patients, representing an 86.8% success rate, than in the tetracyline and bleomycin groups, with seven (26.7%) and five (35.7%) patients, respectively, representing 73.8% and 64.3% success rates (P = 0.04).ConclusionsTalc resulted in the earliest expansion, minimal drainage, and the earliest tube and catheter removal.

Unusual radiologic manifestations of the echinococcus infection in the thorax.

Unusual location and presentation of hydatid cyst disease in the thorax requires careful consideration with respect to clinical approach and therapy. In this pictorial essay, we present imaging findings and describe treatment of thoracic hydatid cysts in patients with lung, mediastinal, chest wall, cardiac, endobronchial, pulmonary artery, and diaphragmatic involvement. A review of the literature is also included.

A different application method of talc pleurodesis for the treatment of persistent air leak.

Persistent air leak is a serious problem that may cause empyema, hypoxia, respiratory insufficiency, and other life‐threatening complications. Chemical pleurodesis may be carried out for the treatment of persistent air leak if the lung is fully expanded. However, the standard method of chemical pleurodesis entails clamping the chest tube for a period of time after instillation of the agent. In patients with massive air leak, this would result in a tension pneumothorax. Therefore, standard chemical pleurodesis for persistent air leak is not an appropriate treatment for these patients. In this study, we carried out talc pleurodesis in six patients using an inverted U‐shaped chest tube elevated to 60 cm that did not result in tension pneumothorax and mediastinal shift. No recurrence was observed during a mean follow up of 16.2 months.

Comparison of Mersilene Mesh–Methyl Metacrylate Sandwich and Polytetrafluoroethylene Grafts for Chest Wall Reconstruction

We report the outcomes of patients who underwent reconstruction with Mersilene mesh–methyl methacrylate (MM–MM) sandwich and polytetrafluoroethylene (PTFE) grafts after a large chest wall resection. Between June 1990 and September 2001, 59 consecutive patients (37 men, 22 women; mean age, 48.1 ± 11.8 years; range 22–74 years) underwent large chest wall resection (greater than 5 cm diameter) and reconstruction with prosthetic material in our department. Twenty-one patients (33%) underwent reconstruction with a PTFE graft (group 2) between 1990 and 1994, and 38 patients (67%) underwent reconstruction with an MM–MM sandwich graft (group 1) between 1994 and 2001. Operative morbidity ratios were 5.2% (2/38) in group 1 and 24% (5/21) in group 2 (p =. 036). The paradoxical respiration ratio was significantly higher (p =. 018) in group 2 (5/21: 24%) than it was in group 1 (1/38: 2.6%). The operative mortality ratio was 4.5% (1/21) in group 2 and 0% in group 1. Mean hospital stay was 10.6 days (range 5–21 days) in group 1 and 13.3 days (range 7–36 days) in group 2 (p =. 015). The MM–MM graft is inexpensive and easy to apply, provides better cosmetic options, and offers minimal morbidity. We therefore recommend that the MM–MM sandwich graft be used rather than the PTFE graft for large defects of the anterolateral chest wall and sternum where successful prevention of paradoxical respiration is required.

A Very Rare Entity: Catamenial Pneumothorax

Catamenial pneumothorax, a variant of spontaneous pneumothorax occurs exclusively in women of menstrual age. Catamenial pneumothorax is associated with a high rate of recurrence. The etiology and pathogenesis is enigmatic. We describe the case of a 42-year-old woman with right-sided catamenial pneumothorax recurring four times, caused by ectopic endometriosis in the pleural layers which was confirmed histopathologically. Surgical treatment should be accomplished during menstruation for optimal visualization of pleurodiaphragmatic endometriosis.

Factors affecting morbidity and mortality in flail chest: comparison of anterior and lateral location.

OBJECTIVE Flail chest is most often accompanied by significant underlying pulmonary parenchymal injuries and may constitute a life-threatening thoracic injury. In this study we evaluated the treatment modalities for flail chest depending on the effect of trauma localization on mortality and morbidity. METHODS Between 2003 and 2008, 23 patients (20 males/3 females) were treated for flail chest. Location of the trauma in the chest wall, mechanical ventilation support, prognosis and injury severity score (ISS) were recorded for all patients. Mechanical ventilation support was given in 14 patients (60.8 %), and 12 of these 14 patients required subsequent tracheostomy. Internal fixation was used in 3 patients. RESULTS The major cause of flail chest was a car crash in 18 of 23 patients (76 %). Median ISS was 62.8 for all patients. The patients with flail chest who had bilateral costochondral separation (anterior chest location) (group I, n = 10) had a significantly higher ISS than those with single-side posterolateral flail chest (group II, n = 13; ISS: 70/55; P = 0.02). The need for mechanical ventilation support was also higher in the group with bilateral costochondral separation. Morbidity was higher in group I than in group II ( P = 0.198), and mortality was also significantly higher in group I ( P = 0.08). Patients with a cranial trauma and flail chest had a higher mortality (19 %) than patients with only flail chest (no mortality). The mean ISS was 75 for patients with cranial trauma and flail chest and 55.7 ( P = 0.001) for patients with only flail chest. Sepsis and subarachnoid bleeding were the major causes of mortality. The mean ISS was 54.5 for patients under the age of 55 (n = 14) whereas it was 69.4 in those aged 55 and over (n = 9; P = 0.034). Mortality in the older group was also higher (33 % versus 7 %; P = 0.02). CONCLUSION Early intubation and mechanical ventilation is of paramount importance in patients with flail chest. However, prolonged mechanical ventilation is associated with a poor outcome. Tracheotomy and frequent flexible bronchoscopy are an effective pulmonary toilet. Advanced age was a major risk factor for flail chest trauma mortality, together with the severity of the injury. When cranial trauma was accompanied by flail chest, mortality and morbidity rates increased. Bilateral costochondral separation also increased the risk of morbidity and the need for mechanical ventilation in patients with flail chest.

MANAGEMENT OF COMPLICATED HYDATID CYST OF THE THORAX

Background:  Complicated hydatid cyst of the thorax is important to the clinical approaches and treatment methods in hytadid disease. The aim of this study was to evaluate the problems of complicated pulmonary hytatid cyst, including choice of surgical methods, diagnostic clues and to discuss the inherent risks of medical theraphy and the delay of surgical treatment in pulmonary hydatid disease.

Multiple primary chest wall hydatid cysts associated with spinal canal involvement

Primary multiple chest wall hydatid cysts associated with spinal canal involvement through an intervertebral foramen is an uncommon clinical entity. We present a 54-year-old man who underwent cystotomy and total resection of ribs five through seven via a left posterolateral thoracotomy followed by Th5-Th6 anterolateral partial pediculotomies for removal of cysts in the spinal canal. Although spinal reconstruction was not required, the chest wall defect was repaired with mersilene mesh-methyl methacrylate sandwich graft. Hydatid disease should be considered in the differential diagnosis of mass lesions located in the chest wall. In cases of spinal canal involvement, detailed visualization of spinal canal utilizing MRI and/or CT is essential for planning surgical approach.

Is clipping superior to cauterization in the treatment of palmar hyperhidrosis

BACKGROUND Endoscopic thoracic sympathectomy has been accepted as the most effective treatment for palmar hyperhidrosis (PH). However, there is a debate regarding the surgical techniques in terms of effectiveness, recurrence, and reversibility. In this study, sympathetic chain disruptions were compared in terms of whether the clipping or ablation technique had an effect on the long-term outcomes of patients who underwent thoracic sympathectomy for primary PH. PATIENTS AND METHODS All patients who underwent video-thoracoscopic sympathectomy for PH between May 2008 and October 2011 were included. Single-port bilateral sympathectomy was performed depending on the sweat distribution. As a standard approach, rib-based terminology was used to describe the blockade level of the sympathetic ganglia, and single-level R3 sympathectomy (between R3 and R4) was performed in all patients. The type of sympathectomy was changed. Monopolar electrocautery was first performed and 5-mm clips were then used for nerve disruption. Both techniques were evaluated and compared in terms of effectiveness, reversibility, and recurrence. RESULTS Cauterization of the sympathetic chain was applied in 28 (47%) (Group A) patients and clipping in 32 (53%) patients (Group B). CH was the most common adverse effect and was observed in 43 (71.6%) patients (Group A, 71.4%; Group B, 71.8%; p = 0.8). The success rate was 93% for Group A and 100% for Group B (p = 0.15). The satisfaction rate for Group A was 83% and for Group B was 86% (p = 0.77). In Group A two patients (7%), and in Group B three patients (9%) requested reversibility because of severe compensatory hyperhidrosis. Overly dry hands were the other most common side effect and were identified in 12 (25%) patients. Recurrences were observed in 11 patients in Group A and 4 patients in Group B (19 vs. 6%; p = 0.01). The mean follow-up time was 33 ± 10.5 months (range, 13-53 months). CONCLUSION Both clipping and cauterization are highly effective for the treatment of PH. The methods are comparable in terms of effectiveness and side effects despite the fact that the recurrence rate was higher in the cauterization group. Potential reversibility of compensatory sweating was not observed in our series. Identification of ideal candidates for surgery and education of patients about the permanent side effects of sympathectomy might make these techniques more convenient.
