Bronchial and arterial sleeve resection for centrally-located lung cancers

The use of bronchial and arterial sleeve resections for the treatment of centrally-located lung cancers, when available, has become the option of choice in comparison with pneumonectomy (PN). Technical expertise, in particular in vascular reconstruction, and perioperative management improved over time allowing excellent short-term and long-term results. This is even truer if considering literature data from the main experiences published in the last years. These evidences have given to such lung sparing reconstructive procedures more and more acceptance among the surgical community. This article focuses on the main technical aspects and literature data regarding bronchovascular sleeve resections

Long term compensatory sweating results after sympathectomy for palmar and axillary hyperhidrosis

Endoscopic thoracic sympathectomy is currently the best treatment for primary upper extremity hyperhidrosis, but the potential for adverse effects, particularly the development of compensatory sweating, is a concern and often precludes surgery as a definitive therapy. This study aims to evaluate long-term results of two-stage unilateral versus one-stage bilateral thoracoscopic sympathectomy

A Novel Technique for Laryngotracheal Reconstruction for Idiopathic Subglottic Stenosis

Idiopathic subglottic stenosis is the most challenging condition in the field of upper airway reconstruction. We describe a successful novel technique for enlarging the airway space at the site of the laryngotracheal anastomosis in very high-level reconstructions

Successful treatment of cerebral arterial gas embolism following uneventful TBNA

Fibrobronchoscopy is commonly considered a safe procedure with a low major complication rate not including cerebral arterial gas embolism (CAGE) a severe life threatening iatrogenic complication. Several cases of transbronchial needle aspiration (TBNA) has been related with CAGE when patient happens to have the high airway pressure that exceeds the pressure of the pulmonary veins allowing the air to enter the systemic circulation through the left heart. HBOT is the only effective treatment available for CAGE that provides 100% oxygen at high pressure, which accelerates nitrogen reabsorption and improves oxygenation of ischemic tissue. We reported a case of successful treatment with full recovery after early Hyperbaric Oxygen therapy of CAGE induced by an uneventful transbronchial biopsy during fibrobronchoscopy

A modified technique to simplify external fixation of the subglottic silicone stent

Several techniques have been previously proposed to fix silicone stents for subglottic tracheal stenosis. However, they require special tools or cumbersome manoeuvres. The proposed modified procedure offers a potential alternative fixing technique using absorbable suture buried subcutaneously and not requiring special devices. This procedure was successfully performed in 27 patients with inoperable complex subglottic stenosis. The mean distance from vocal folds, the mean length and mean diameter of stenosis were 17 ± 2 mm, 20 ± 2.9 mm and 6.9 ± 0.9 mm, respectively. The mean procedural time for fixing the stent was 5 ± 0.3 min. No intraoperative or postoperative complications such as stent damage, dislocation, plugging or vocal folds dysfunction were reported (mean follow-up 20 ± 7.7 months)

Reconstruction of the heart and the aorta for radical resection of lung cancer

Introduction: We report a single-center experience of resection and reconstruction of the heart and aorta infiltrated by lung cancer in order to prove that involvement of these structures is no longer a condition precluding surgery. Methods: Twenty-seven patients underwent surgery for lung cancer presenting full-thickness infiltration of the heart (n = 6) or the aorta (n = 18) and/or the supra-aortic branches (subclavian n = 3). Cardiac reconstruction was performed in 6 patients (5 atrium, 1 ventricle), with (n = 4) or without (n = 2) cardiopulmonary bypass, using a patch prosthesis (n = 4) or with deep clamping and direct suture (n = 2). Aortic or supra-aortic trunk reconstruction (n = 21) was performed using a heart-beating crossclamping technique in 14 cases (8 patch, 4 conduit, 2 direct suture), or without crossclamping by placing an endovascular prosthesis before resection in 7 (4 patch, 3 omental flap reconstruction). Neoadjuvant chemotherapy was administered in 13 patients, adjuvant therapy in 24. Results: All resections were complete (R0). Nodal staging of lung cancer was N0 in 14 cases, N1 in 10, N2 in 3. No intraoperative mortality occurred. Major complication rate was 14.8%. Thirty-day and 90-day mortality rate was 3.7%. Median follow-up duration was 22 months. Recurrence rate is 35.4% (9/26: 3 loco-regional, 6 distant). Overall 3- and 5-year survival is 60.9% and 40.6%, respectively. Conclusions: Cardiac and aortic resection and reconstruction for full-thickness infiltration by lung cancer can be performed safely with or without cardiopulmonary bypass and may allow long-term survival of adequately selected patients

Low-dose buprenorphine infusion to prevent postoperative hyperalgesia in patients undergoing major lung surgery and remifentanil infusion: a double-blind, randomized, active-controlled trial

Abstract Background Postoperative secondary hyperalgesia arises from central sensitization due to pain pathways facilitation and/or acute opioid exposure. The latter is also known as opioid-induced hyperalgesia (OIH). Remifentanil, a potent μ-opioid agonist, reportedly induces postoperative hyperalgesia and increases postoperative pain scores and opioid consumption. The pathophysiology underlying secondary hyperalgesia involves N-methyl-D-aspartate (NMDA)-mediated pain pathways. In this study, we investigated whether perioperatively infusing low-dose buprenorphine, an opioid with anti-NMDA activity, in patients receiving remifentanil infusion prevents postoperative secondary hyperalgesia. Methods Sixty-four patients, undergoing remifentanil infusion during general anaesthesia and major lung surgery, were randomly assigned to receive either buprenorphine i.v. infusion (25 μg h −1 for 24 h) or morphine (equianalgesic dose) perioperatively. The presence and extent of punctuate hyperalgesia were assessed one day postoperatively. Secondary outcome variables included postoperative pain scores, opioid consumption and postoperative neuropathic pain assessed one and three months postoperatively. Results A distinct area of hyperalgesia or allodynia around the surgical incision was found in more patients in the control group than in the treated group. Mean time from extubation to first morphine rescue dose was twice as long in the buprenorphine-treated group than in the morphine-treated group: 18 vs 9 min ( P =0.002). At 30 min postoperatively, patients receiving morphine had a higher hazard ratio for the first analgesic rescue dose than those treated with buprenorphine ( P =0.009). At three months, no differences between groups were noted. Conclusions Low-dose buprenorphine infusion prevents the development of secondary hyperalgesia around the surgical incision but shows no long-term efficacy at three months follow-up

Unidirectional endobronchial valves for management of persistent air-leaks. Results of a multicenter study

Background: To evaluate the efficacy of Endo-Bronchial Valves in the management of persistent air-leaks (PALs) and the procedural cost. Methods: It was a retrospective multicenter study including consecutive patients with PALs for alveolar pleural fistula (APF) undergoing valve treatment. We assessed the efficacy and the cost of the procedure. Results: Seventy-four patients with persistent air leaks due to various etiologies were included in the analysis. In all cases the air leaks were severe and refractory to standard treatments. Sixty-seven (91%) patients underwent valve treatment obtaining a complete resolution of air-leaks in 59 (88%) patients; a reduction of air-leaks in 6 (9%); and no benefits in 2 (3%). The comparison of data before and after valve treatment showed a significant reduction of air-leak duration (16.2±8.8 versus 5.0±1.7 days; P<0.0001); chest tube removal (16.2±8.8 versus 7.3±2.7 days; P<0.0001); and length of hospital stay (LOS) (16.2±8.8 versus 9.7±2.8 days; P=0.004). Seven patients not undergoing valve treatment underwent pneumo-peritoneum with pleurodesis (n=6) or only pleurodesis (n=1). In only 1 (14%) patient, the chest drainage was removed 23 days later while the remaining 6 (86%) were discharged with a domiciliary chest drainage removed after 157±41 days. No significant difference was found in health cost before and after endobronchial valve (EBV) implant (P=0.3). Conclusions: Valve treatment for persistent air leaks is an effective procedure. The reduction of hospitalization costs related to early resolution of air-leaks could overcome the procedural cost

Surgical treatment of lung cancer with adjacent lobe invasion in relation to fissure integrity

Background Tumor with adjacent lobe invasion (T‐ALI) is an uncommon condition. Controversy still exists regarding the optimal resection of adjacent lobe invasion, and the prognostic value in relation to fissure integrity at the tumor invasion point. The aims of this paper were to evaluate the prognosis of T‐ALI with regard to fissure integrity, and type of resection. Methods This was a retrospective multicenter study which included all consecutive patients with T‐ALI undergoing surgical treatment. Based on radiological, intraoperative and histological findings, T‐ALI patients were differentiated into two groups based on whether the fissure was complete (T‐ALI‐A group) or incomplete (T‐ALI‐D Group) at the level of tumor invasion point. Clinico‐pathological features and survival of two study groups were analyzed and compared. Results Study population included 135 patients, of these 98 (72%) were included into T‐ALI‐A group, and 37 (38%) into T‐ALI‐D Group. T‐ALI‐D patients had better overall survival than T‐ALI‐A patients (63.9 ± 7.0 vs. 48.9 ± 3.9; respectively, P = 0.01) who presented with a higher incidence of lymph node involvement (35% vs. 4%; P = 0.004), and recurrence rate (43% vs. 16%; P = 0.01). At multivariable analysis, T‐ALI‐D (P = 0.01), pN0 stage (P = 0.0002), and pT≤5 cm (P = 0.0001) were favorable survival prognostic factors. Conclusions T‐ALI‐D presented a better prognosis than T‐ALI‐A while extent of resection had no effect on survival. Thus, in patients with small T‐ALI‐D and without lymph node involvement, sublobar resection of adjacent lobe rather than lobectomy could be indicated. Key points The extent of resection of adjacent lobe had no effect on survival while T‐ALI‐D, pN0 stage, and pT≤5 cm were significant prognostic factors. In patients with small T‐ALI‐D and without lymph node involvement, sublobar resection of adjacent lobe could be indicated as an alternative to lobectomy
