[Pulmonary decortication: value of lung function recovery]. / La décortication pulmonaire : intérêt dans la récupération de la fonction respiratoire.

PURPOSE: Based on the experience in the thoracic surgery unit at Hôpital Militaire d'Instruction Mohammed-V in Rabat, this study analyses the indications as well as the results of pulmonary decortication. MATERIALS AND METHODS: Twenty-five cases of pulmonary decortication were examined over a period of 5 years ranging from January 2002 to December 2006. The aetiology of chronic pyothorax was dominated by non tubercular causes. The clinical symptomatology mainly involved fever and dyspnoea (48% and 44% respectively). Pachypleuritis, collapse of the lung and pleural effusion account for most of the lesions found on the thoracic imaging. Surgery was indicated after failure in the medical treatment after four months on the average. RESULTS: The respiratory function was assessed in 20 patients three months after the intervention. The improvement in the spirometry was good in 85% of the cases (n=17), was not highly satisfactory in 10% of the cases (n=2) and a deterioration was noted in 5% of the cases (n=1). This unfavourable evolution was correlated with the tubercular aetiology and the poor state of the pulmonary parenchyma. CONCLUSION: Non tubercular causes, early diagnosis and absence of parenchymatous lesion seem to be predictive factors of good results after decortication.

[The surgical extraction of foreign bodies after the inhalation of a scarf pin: two cases]. / Deux cas d'extraction chirurgicale de corps étrangers après inhalation d'épingle de foulard.

The inhalation of a foreign body (FB) is rare in the adult although more common in the child. The type of FB varies greatly according to the dietary and educational habits of the populations studied. In Morocco, metal FB are common, especially the pins used to attach scarves. These pins migrate easily and wedge at a distance making them difficult to extract by endoscopy, thereby resulting in thoracotomy. The authors present two cases of the inhalation of a pin held in the mouth during a sudden emotion. Since the clinical symptomatology is inconspicuous, thoracic imaging is used to locate the FB. After a failure to extract it by rigid bronchoscopy combined with flexible bronchoscopy, the two patients underwent surgery. The sequellae were simple. Prevention in both the child and in the adult are the best way to avoid this incident that may have dramatic results.

[Primary leiomyosarcoma of visceral mediastinum]. / Léiomyosarcome primitif du médiastin viscéral.

Primary leiomyosarcoma of the thorax is a rare malignant mesenchymatous tumour. Most of those tumours occurring in the mediastinum arise from the oesophagus and great vessels, whereas an appearance in the soft tissue of the mediastinum is extremely rare. The rare incidence of this tumour and its slow growth reflect the difficulties in differential diagnosis according to their histopathology and location. The most common treatment is surgical resection. The authors describe a case of a leiomyosarcoma arising from soft tissue of the mediastinum and present a review of the literature.

[Pulmonary intralobar sequestration in adults: Evolution of surgical treatment]. / Séquestrations pulmonaires intralobaires de l'adulte : évolution du traitement chirurgical.

BACKGROUND: Until now, the traditional procedure to treat intralobar pulmonary sequestration (ILS) in adults has been a lobectomy performed by open thoracotomy. We have reviewed our data to observe if the surgical management of these lesions has evolved over the last years. METHODS: We retrospectively reviewed the records of the patients who were operated for an ILS either by posterolateral thoracotomy (PLT group), or by thoracoscopy (TS group) between 2000 and 2016. RESULTS: Eighteen patients were operated for a SIL during this period. Prior to 2011, all resections were performed by thoracotomy (n=6) and after 2011 the surgical approach was either a thoracotomy (n=5) or a thoracoscopy (n=7). There was one conversion because of dense pleural adhesions and this patient was integrated in the PLT group for further analysis. ILS were more frequently encountered on the left side (n=12, 66.6 %) than on the right one (n=6, 33.3 %) and exclusively in the lower lobes. All patients of the PLT group underwent a lobectomy. In the TS group, 5 patients underwent a sublobar resection (2 segmentectomiesS9+10, 1 basilar segmentectomy and 2 atypical resections). There was no mortality. In the PLT group, 5 patients (45 %) had complications versus one patient (14 %) in the TS group. The mean hospital stay was 7.4 days in the PLT group versus 5.4 days in the TS group. CONCLUSIONS: These data confirm that ILS can be safely treated by a sublobar resection that should be performed, whenever possible, thoracoscopically.

[Chronic chest pain after rib fracture: It can cause a disability?] / La douleur thoracique chronique après fracture de côtes : peut-elle causer une invalidité ?

INTRODUCTION: The rib fractures and instability of the chest wall are the main lesions of closed chest trauma. These lesions can be a source of chronic, often disabling with daily discomfort resulting limitation of some activities. The objective of this study was to assess the prevalence of this phenomenon in order to improve the quality of early care. METHODOLOGY: Through an observational retrospective cohort study on a number of 41 patients supported and monitored for traumatic rib fractures at the Military Hospital of Meknes during the period from October 2010 to March 2016. RESULTS: The circumstances of the accident were dominated by accidents of public roads (86%) and concerned the young adult male. Radiographs have enumerated 165 fracture lines with an average of 4 rib fractures per patient. These were unilateral fractures in 88% of cases, and concerned the means arc in 46% of cases. The rib fracture was undisplaced fracture in 39% of patients, whereas in 2 patients, a flail chest was present. Post-traumatic hemothorax (63% of cases) were the thoracic lesions most commonly associated with rib fractures. The initial management consisted in the use of analgesics systemically in all patients. The retrospective evaluation of pain by the verbal scale was possible in 30 patients. The persistent pain was noted in 60% of cases. This pain was triggered by a simple effort to moderate in 55% of cases, and hard effort in 28% of cases. In 17% of patients, even at rest, the pain occurred intermittently. The impact in terms of disability was mild to moderate in 28% of cases and important in 17%. The neuropathic pain was found in 3 patients. Therapeutically, the first and second levels of analgesics were sufficient to relieve pain. The neuroleptics were required for 2 patients. CONCLUSION: Our study confirms the persistence of chronic painful, sometimes lasting several years after the initial chest trauma. This pain is responsible of disability triggered most often after exercise.

Surgical treatment of aspergilloma grafted in hydatid cyst cavity.

Aspergilloma is a saprophytic infection that colonizes pre-existing cavities in the lung. These cavities are caused by tuberculosis, bronchiectasis, lung cancer and other pulmonary diseases. Development of aspergilloma in the residual cavities after pulmonary hydatid cyst surgery is rarely described in terms of coexistence of the two conditions. We describe 3 cases of pulmonary aspergilloma grafted in a residual cavity of cystectomy for hydatid disease.

[Benign cysts of the mediastinum: series of 28 cases]. / Les kystes bénins du médiastin : à propos de 28 cas.

INTRODUCTION: Benign cystic mediastinal mass form a group of heterogeneous and uncommon lesions. Surgical resection is the gold standard in these conditions. We reported our institutional experience in management of these benign tumours. In this review, cardiac and ganglionary benign mass were excluded. METHODS: We retrospectively reviewed the records of 28 patients with benign cysts of the mediastinum, who are operated in our department between January 2003 and December 2009 (7years period). RESULTS: There were 13 females (46.4%) and 15 males (53.5%), with a mean age of 36.8years (range: 13-63years). Most lesions (n=22) were equally in the anterior and middle mediastinum, only six were in the posterior mediastinum. Seventeen patients (60.7%) were symptomatic, with chest pain and cough as the most common symptoms. The diagnosis of mediastinal cyst was fortuitous in 11 patients with the waning of an assessment made for another reason. Surgery was indicated in all patients in order to both diagnostic and therapeutic. Posterolateral thoracotomy incision is the most common. Complete resection of the cyst was possible only in 18 cases (64.3%), whereas in ten (35. 7%) other cases part of the cyst was left in place due to tight adhesions to vital structures. After histological study, there were: nine bronchogenic cysts (32.1%), seven hydatid cysts (25%), four cystic lymphangiomas (14.3%), three mature cystic teratomas (10.7%) and three pleuropericardial cysts, one thymic cyst and one parathyroid cyst. The postoperative course was uneventful and no recurrence has been observed until now. CONCLUSION: The benign cysts of the mediastinum is a rare entity, the hydatid etiology remains common in our context. Surgical treatment remains the treatment of choice for mediastinal cysts, when the patient is operable, to save the risk of complications or degeneration.

[Missed right post-traumatic diaphragmatic injuries: a review of six cases]. / Les lésions diaphragmatiques post-traumatiques droites méconnues : une revue de six cas.

INTEREST: Right posttraumatic diaphragmatic injuries are rare; literature relates mainly isolated cases or small series and most often rupture are succeeding of blunt trauma. This series is interesting because the number of cases and the existence of two injuries following a right stab wound. PATIENTS AND METHODS: Retrospective study between January 2002 and September 2010. We collected the data of initial trauma, clinical, radiological, operative and follow-up for six patients supported for right posttraumatic diaphragmatic injuries. RESULTS: All injuries were in late presentation. Four injuries were secondary to road traffic accident, and two after stab wound. The time to diagnosis was between 47 days and 15 years. Right posterolateral thoracotomy was the elective approach in the cases with diaphragmatic hernia (5 patients). In one case, video-assisted thoracoscopic surgery permits the diagnosis and repair of injury. Mortality was null and morbidity was present in one case from six. Follow-up ranging from 8 months and 42 months don't objectified complications. CONCLUSION: Right diaphragmatic hernia is terrible sequelae after thoracoabdominal trauma. Surgery becomes more complex at this stage and can be done by thoracotomy. With strong suspicious signs at the first assessment of trauma, exploration by thoracoscopy can always avoid the occurrence of long-term sequelae.

[Bilio-bronchial fistula due to hydatic disease: case report and review of the literature]. / Fistule bilio-bronchique d'origine hydatique : à propos d'un cas et revue de la littérature.

Bilio-bronchial fistula due to hydatid disease is a rare but severe condition. Three levels, abdominal, diaphragmatic and thoracic, may be involved, with high perioperative mortality. We report a case of bilio-bronchial fistula successfully managed by thoracotomy. Thoracotomy is the best approach for surgical treatment at all three levels.

[Pediatric Ewing sarcoma of the rib: role of neoadjuvant chemotherapy in tumoral shrinking and sterilization. A case report]. / Sarcome d'Ewing costal chez l'enfant : intérêt de la chimiothérapie néoadjuvante dans la réduction et la stérilisation tumorale. À propos d'un cas.

Ewing sarcoma is a rare tumor, which represents, nevertheless, the most common primary chest wall tumor in children. The management and prognosis of these tumors have markedly improved with the use of multimodal therapy including adjuvant chemotherapy, surgery and/or irradiation. A good response to chemotherapy often avoids the need for extensive local treatment without sacrificing local control or long-term survival. Here, we report a new case of a bulky rib Ewing sarcoma, well managed by neoadjuvant chemotherapy resulting in significantly tumor shrinking that allowed complete resection. At the histological examination of the specimen, there was only inflammatory and fibrosis tissues without viable tumoral tissue.

[Myopericytoma: an uncommon chest wall tumor]. / Le myopéricytome : une tumeur exceptionnelle de la paroi thoracique.

Myopericytoma is, according to the World Health Organisation classification of soft tissue tumours, a recently proposed term describing a group of tumours showing a perivascular myoid differentiation. It is a rare tumour with a predilection for the distal extremities and is often misdiagnosed. We report a new case of myopericytoma located exceptionally in the chest wall together with a review of literature.
