To assess the effect of paravertebral administration of dexmedetomidine as an adjuvant to local anesthetic on the intraoperative anesthetic drug requirement and incidence of post-thoracotomy pain syndrome. Prospective, randomized, controlled, double-blind trial. Single university hospital. The study comprised 30 patients who underwent elective thoracotomy and were assigned randomly to either the Ropin or Dexem group (n = 15 each). All patients received the study medications through paravertebral catheter. Patients in the Ropin group received a bolus of 15 mL of 0.75% ropivacaine over 3-to-5 minutes followed by an infusion of 0.2% ropivacaine at 0.1 mL/kg/hour. Patients in the Dexem group received 15 mL of 0.75% ropivacaine plus dexmedetomidine, 1 µg/kg bolus over 3-to-5 minutes followed by an infusion of 0.2% ropivacaine plus 0.2 µg/kg/hour of dexmedetomidine at 0.1 mL/kg/hour. The primary outcome of the study was intraoperative anesthetic drug requirement. The secondary outcome was the incidence of post-thoracotomy pain syndrome 2 months after surgery. The amount of propofol required for induction of anesthesia was significantly less in the Dexem group (Dexem 49.33±20.51 v 74.33±18.40 in the Ropin group, p = 0.002). End-tidal isoflurane needed to maintain target entropy was significantly less in the Dexem group at all time points. Intraoperative fentanyl requirement was lower in the Dexem group (Dexem 115.33±33.77 v 178.67±32.48 in the Ropin group, p = 0.002). Postoperative pain scores and morphine consumption were significantly less in the Dexem group (p<0.001). The incidence of post-thoracotomy pain syndrome was comparable between the 2 groups (69.23% v 50%, p = 0.496). Paravertebral dexmedetomidine administration resulted in decreased intraoperative anesthetic drug requirement, less pain, and lower requirements of supplemental opioid in the postoperative period. However, it had no effect on the incidence of post-thoracotomy pain syndrome. Copyright © 2017 Elsevier Inc. All rights reserved.

Removing or sampling lymph nodes from the bilateral paratracheal area through a left thoracotomy is not a standard procedure in patients with lung cancer. The aim of this study was to evaluate the feasibility of a technique without ductus arteriosus division and mobilization of the aortic arch and to compare the number of lymph nodes resected in left-sided dissections to the number of lymph nodes removed in right-sided mediastinal dissections that are routinely performed in clinical practice. A total of 93 patients with hilar lung cancer were evaluated. A prospective study was conducted on 51 patients with primary left-sided hilar lung cancer, who underwent left thoracotomy and paratracheal lymphadenectomy between January 2008 and January 2010. The number of nodes dissected in these patients was compared with the number of nodes dissected in 42 patients with right-sided hilar lung cancer by right-sided mediastinal dissection within the same period. The mean number of resected nodes in the bilateral paratracheal area via left thoracotomy was 8.4 (2-18 nodes). The distribution from 4R-4L-2L-2R was as follows: 3.3-2.5-0.5-2.1, respectively. Six patients (11.7%) were diagnosed with occult N2, and two (3.9%) of these patients also had N3 disease concomitantly. The number of dissected nodes from the ipsilateral station 2 via right-sided versus left-sided thoracotomy was 1.6 versus 0.5 (p=0.000), whereas the number of dissected nodes from ipsilateral station 4 via right-sided versus left-sided thoracotomy was 3.3 versus 2.5, respectively (p=0.1). The number of dissected nodes from the contralateral station 2 via right-sided versus left-sided thoracotomy was 0.2 versus 2.1 (p=0.000), whereas those numbers from the contralateral station 4 via right-sided versus left-sided thoracotomy were 1.0 versus 3.3, respectively (p=0.000). Lymphadenectomy of the paratracheal area via left thoracotomy without ductus arteriosus division and mobilization of the aortic arch is technically feasible. From these data, regardless of approach, more lymph nodes are obtained from the right paratracheal space; this appears to be due to the fact that there are more right-sided paratracheal lymph nodes.

Romanoff, H

1975-01-01

Infection is a major complication of military chest injuries. In a series of 142 wounded, infectious complications occurred in 7 (4.9%). Factors influencing the incidence of infection are evaluated. In this group of injuries, 81 patients were admitted soon after wounding. The intrathoracic damage was severe, due to penetration of metallic fragment. The hemothorax was treated by immediate intercostal drainage. Immediate thoracotomy was performed in 10 patients and late thoractomy in 15. One patient developed a lung abscess and 5 patients had infection following thoracotomy (7.4%). Another 61 wounded patients had been first managed in a forward hospital, including three with thoractomy for massive bleeding. Two, not in a forward hospital, had a bullet removed from the lung. Upon admission to this hospital, intercostal drains were inserted when needed and four patients underwent thoracotomy. Larger wounds were debrided in 24 patients. Late thoracotomy was perfromed in seven. Chronic empyema developed in one patient after pneumonectomy performed at the field hospital, resulting in a resuscitation or infection rate of less than 2%. Factors contributing to a low infection rate were: early drainage of hemothoraces and wide debridement of larger wounds with delayed closure and avoidance of thoracotomy as primary treatment. Resection of lung tissue was avoided. Thoraco-abdominal injuries were treated separately. The clotted hemothorax was immediately evacuated. Prolonged antibiotic therapy was usually indicated.

Andrade-Alegre, Rafael; Garisto, Juan D.; Zebede, Salomón

2008-01-01

OBJECTIVES Traditionally, chronic empyema has been treated by thoracotomy and decortication. Some recent reports have claimed similar clinical results for videothoracoscopy, but with less morbidity and mortality than open procedures. Our experience with thoracotomy and decortication is reviewed so that the results of this surgical procedure can be adequately evaluated. MATERIALS AND METHODS From March 1992 to June 2006, 85 patients diagnosed with empyema were treated at Santo Tomás Hospital by the first author. Diagnosis of chronic empyema was based on the duration of signs and symptoms before definitive treatment and imaging findings, such as constriction of the lungs and the thoracic cage. Thirty-three patients fulfilled the criteria for chronic empyema and underwent open thoracotomy and decortication. RESULTS Twenty-seven patients (81.8 %) were male and the average age of the study group was 34 years. The etiology was pneumonia in 26 patients (78.8%) and trauma in 7 (21.2%). The duration of symptoms and signs before definitive treatment averaged 37 days. All patients had chronic empyema, as confirmed by imaging studies and operative findings. Surgery lasted an average of 139 min. There were 3 (9%) complications with no mortality. The post-operative length of stay averaged 10 days. There were no recurrences of empyema. CONCLUSIONS Open thoracotomy and decortication can be achieved with low morbidity and mortality. Long-term functional results are especially promising. We suggest that the validation of other surgical approaches should be based on comparative, prospective and controlled studies. PMID:19061002

In clinical practice, the mechanisms underlying chronic post-surgical pain (CPSP) remain insufficiently understood. The primary goals of this study were to determine the incidence of chronic pain after thoracic surgery and to identify possible risk factors associated with the development of chronic post-thoracotomy pain in Chinese patients. The secondary goal was to determine whether the difference between pre- and post-operative white blood cell (WBC) counts could predict the prevalence of CPSP after thoracotomy. The impact of chronic pain on daily life was also investigated. We contacted by phone 607 patients who had undergone thoracotomy at our hospital during the period February 2009 to May 2010. Statistical comparisons were made between patients with or without CPSP. were ultimately analyzed from 466 qualified patients. The overall incidence of CPSP was 64.5%. Difference between pre- and post-operative WBC counts differed significantly between patients with or without CPSP (P < 0.001) and was considered as an independent risk factor for the development of CPSP following thoracotomy (P < 0.001). Other predictive factors for chronic pain included younger age (< 60 years, P < 0.001), diabetes mellitus (P = 0.023), acute post-operative pain (P = 0.005) and the duration of chest tube drainage (P < 0.001). At the time of interviews, the pain resulted in at least moderate restriction of daily activities in 15% of the patients, of which only 16 patients had paid a visit to the doctor and only three of them were satisfied with the therapeutic effects. Chronic pain is common after thoracotomy. WBC count may be a new independent risk factoring surgical patients during peri-operative period. Besides, age, diabetes mellitus, acute post-operative pain, and duration of chest tube drainage may also play a role in chronic post-surgical pain occurrence.

Repeat sternotomy for left ventricular assist device insertion may result in injury to the right heart or patent coronary grafts, complicating intraoperative and postoperative management. In 4 critically ill patients, left thoracotomy was used as an alternative to repeat sternotomy. Anastomosis of the outflow conduit to the descending thoracic aorta provided satisfactory hemodynamic support.

To describe a modified rib pivot thoracotomy and its clinical application in client-owned dogs and cats. Case series of 24 dogs and 1 cat requiring a thoracotomy. A lateral thoracic incision over the required thoracic segment was made. The latissimus dorsi muscle was reflected dorsally. The predetermined rib was identified and the periosteum overlying the rib was elevated circumferentially, avoiding the intercostal neurovascular structures. Holes were pre-placed above and below the proposed osteotomy site. The rib was osteotomised and pivoted cranially. The pleura was incised and the required intrathoracic procedure was then performed. The thoracic cavity was closed by pre-placement of a suture through the pre-placed holes within the osteotomised rib. The pleura and intercostal musculature were closed, avoiding the intercostal neurovascular structures. The rib was re-apposed and the lateral approach was closed. The cases included were reviewed for both the rib pivoted as per the procedure required and postoperative complications. The study group comprised 8 Staffordshire Bull Terriers, 2 Poodles, 2 German Shepherd Dogs, 1 each of Basset Hound, Rhodesian Ridgeback, Golden Retriever, Australian Shepherd, Vizsla, Bull Mastiff, Schnauzer, Jack Russell Terrier, Bulldog, Deerhound, Labrador Retriever and Australian Terrier, and 1 cat. A modified rib pivot thoracotomy was performed for lung lobectomy (n = 11), oesophagectomy (7), subtotal pericardectomy (5), patent ductus arteriosus ligation (1) and thoracic duct ligation (1). Follow-up ranged from 2 to 40 weeks postoperatively. Postoperative complications included seroma formation in two dogs. A modified rib pivot thoracotomy should be considered as an alternative lateral thoracic approach with good exposure, minimal complications and low morbidity. © 2018 Australian Veterinary Association.

Video-assisted thoracoscopic surgery (VATS) represents at present the most suitable treatment of recurrent spontaneous pneumothorax. After three years we consider this interesting to draw up a trial balance of our VATS experience in comparison with the cases treated before 1991 with the classic thoracotomic approach. We have considered retrospectively the results obtained in a series of 30 consecutive patients with recurrent spontaneous pneumothorax treated with VATS between November 1991 and August 1994 in comparison with those obtained in a group of 30 patients previously treated with a traditional thoracotomy. The groups have been selected in such a way that surgical indications, sex ratio, age and number of episodes were homogeneous. The parameters we have compared were the postoperative complications, the duration of chest drainage and hospitalization, the operating times and the relapses. Besides these technical parameters we considered the economic data too. On average drains removal occurred one day before in VATS-Group: the time spent in the Hospital was significantly shorter in VATS-Group, being on average 1 week. Short term complications may be considered similar in the two Groups. Prolonged air leaks occurred in 13% and 16% respectively. Emothorax requesting reoperation occurred in 1 case for each Group. One death occurred in thoracotomy-Group in an old patient presenting a severe chronic respiratory insufficience with exacerbation in postoperative time. We have registered 2 relapses after VATS and none after thoracotomy. The study has demonstrated the therapeutic efficacy of VATS and in the same time that in VATS the total economic cost is lower (22.7%) in comparison with traditional thoracotomy.

We started robot-assisted thoracoscopic esophagectomy using the da Vinci surgical system from June 2010 and operated on 30 cases by December 2013. Herein, we examined the usefulness of robot-assisted thoracoscopic esophagectomy and compared it with conventional esophagectomy by right thoracotomy. Patients requiring an invasion depth of up to the muscularis propria with preoperative diagnosis were considered for surgical adaptation, excluding bulky lymph node metastasis or salvage surgery cases. The outcomes of 30 patients who underwent robot-assisted surgery (robot group) and 30 patients who underwent conventional esophagectomy by right thoracotomy (thoracotomy group) up to December 2013 were retrospectively examined. Five ports were used in the robot-assisted thoracoscopic esophagectomy: 3rd intercostal (da Vinci right arm), 6th intercostal (da Vinci camera), 9th intercostal (da Vinci left arm), 4th and 8th intercostals (for assistance). There was no significant difference in patient characteristics. Robot group/right thoracotomy group: Operation time, 563/398 min; thoracic procedure bleeding volume, 21/135 ml; number of thoracic lymph node radical dissections, 25/23. Postoperative complications were recurrent nerve paralysis, 16.7/16.7%; pneumonia, 6.7%/10.0%; anastomotic leakage, 10.0/20.0%; surgical site infection, 0/10.0%; hospitalization, 17/30 days. For the robot group, the operation time was significantly longer, but the amount of intraoperative bleeding and postoperative hospitalization were significantly reduced. Robot-assisted thoracoscopic esophagectomy enables delicate surgical procedures owing to the 3D effect of the field of view and articulated forceps of the da Vinci. This procedure reduces bleeding and postoperative hospitalization and is less invasive than conventional esophagectomy by right thoracotomy.

Salvage techniques in traumatic cardiac arrest: thoracotomy, extracorporeal life support, and therapeutic hypothermia.

PubMed

Tisherman, Samuel A

2013-12-01

Survival from traumatic cardiac arrest is associated with a very high mortality despite aggressive resuscitation including an Emergency Department thoracotomy (EDT). Novel salvage techniques are needed to improve these outcomes. More aggressive out-of-hospital interventions, such as chest decompression or thoracotomy by emergency physicians or anesthesiologists, seem feasible and show some promise for improving outcomes. For trauma patients who suffer severe respiratory failure or refractory cardiac arrest, there seems to be an increasing role for the use of extracorporeal life support (ECLS), utilizing heparin-bonded systems to avoid systemic anticoagulation. The development of exposure hypothermia is associated with poor outcomes in trauma patients, but preclinical studies have consistently demonstrated that mild, therapeutic hypothermia (34 °C) improves survival from severe hemorrhagic shock. Sufficient data exist to justify a clinical trial. For patients who suffer a cardiac arrest refractory to EDT, induction of emergency preservation and resuscitation by rapid cooling to a tympanic membrane temperature of 10 °C may preserve vital organs long enough to allow surgical hemostasis, followed by resuscitation with cardiopulmonary bypass. Salvage techniques, such as earlier thoracotomy, ECLS, and hypothermia, may allow survival from otherwise lethal injuries.

In quadrupeds, the three-dimensional orientation of the heart with respect to the thorax is fundamentally different from that in humans. In this study, we assessed the best surgical approach to the tricuspid valve in sheep. Firstly, different surgical access sites to the tricuspid valve were tested in sheep cadavers, the anatomy was analyzed, and the optimal surgical approach to the tricuspid valve was determined. Secondly - along with cardiopulmonary bypass and cardioplegic arrest -the chosen approach was tested in six adult sheep in vivo. Anatomical analyses revealed that a left thoracotomy provided optimal access to the aorta and left heart. However, visualization of the right heart was significantly impaired. In contrast, a right thoracotomy provided good access to the right heart, but the ascending aorta was difficult to approach. Therefore, in the in vivo studies, arterial cannulation was performed through a carotid (n = 4) or femoral (n = 2) artery. In conclusion, a right-sided thoracotomy allows good visualization of all components of the tricuspid valve complex in sheep, but not of the ascending aorta. Consequently, peripheral vessels are preferred for arterial cannulation. This work may stimulate the investigation of pathomechanisms and/or novel treatment options for tricuspid valve pathologies.

This report is a preliminary description of the efficacy of video-assisted thoracoscopic surgery in thoracic spinal procedures that otherwise require open thoracotomy. This report sought to describe the efficacy of video-assisted thoracoscopic surgery in thoracic spinal procedures that otherwise require open thoracotomy. In a landmark study that compared video-assisted thoracoscopic surgery for peripheral lung lesions with thoracotomy, video-assisted thoracoscopic surgery reduced postoperative pain, improved early shoulder girdle function, and shortened hospital stay. Video-assisted thoracoscopic surgery was performed in 12 thoracic spinal patients (herniated nucleus pulposus, infection, tumor, or spinal deformity) and is described in detail in this report. Video-assisted thoracoscopic surgery in thoracic spinal surgery resulted in little postoperative pain, short intensive care unit and hospital stays, and little or no morbidity. In the short follow-up period, there was no post-thoracotomy pain syndrome nor neurologic sequelae in these patients. Operative time decreased dramatically as experience was gained with the procedure. Given consistently improving surgical skills, a number of thoracic spinal procedures using video-assisted thoracoscopic surgery, including thoracic discectomy, internal rib thoracoplasty, anterior osteotomy, corpectomy, and fusion, can be performed safely with no additional surgical time or risk to the patient.

Persistent postsurgical pain (PPP) after thoracotomy effect 50% to 80%. Nerve damage and central sensitization involving NDMDAr activation may play an important role. This study evaluates the efficacy of adding intravenous (IV) or epidural ketamine to thoracic epidural analgesia (TEA) after thoracotomy. Double-blind randomized study on patients undergoing thoracotomy allocated to one of the following: group Kiv (IV racemic ketamine 0.5 mg/kg preincisional +0.25 mg/kg/h for 48 h), group Kep (epidural racemic ketamine 0.5 mg/kg preincisional +0.25 mg/kg/h for 48 h), or group S (saline). Postoperative analgesia was ensured by TEA with ropivacaine and fentanyl. Pain visual analog scales (VAS), Neuropathic Pain Symptom Inventory, Catastrophizing Scale, and Quantitative Sensory Testing, measuring both the peri-incisional and distant hyperalgesia area, were conducted preoperatively and postoperatively until 6 months. Plasma ketamine levels and stability of the analgesic solutions were analyzed. A total of 104 patients were included. PPP incidence was 20% at 6 months. Pain scores on coughing were significantly lower in Kiv and Kep than in S at 24 and 72 hours, but there were no differences afterwards. There were no significant differences in pain at rest, Neuropathic Pain Symptom Inventory, and Catastrophizing Scale, or in the area of mechanical allodynia at any time. Adverse effects were mild. Plasma ketamine levels did not differ significantly between groups. Analgesic solutions were stable. Adding epidural or IV racemic ketamine to TEA after thoracotomy did not lead to any reduction in PPP or allodynia. Epidural administration produced similar plasma ketamine levels to the IV route.

The right anterolateral thoracotomy is an alternative technique for surgical approach of mitral valve. In these cases, femoral-femoral bypass still has been used, rising occurrence of complications related to femoral cannulation. Describe the technique and results of mitral valve treatment by right anterolateral thoracotomy using aortic cannulation for cardiac pulmonary bypass (CPB). From 1983 e 2008, 100 consecutive female patients, with average age 35 ±13 years, 96 (96%) underwent mitral valve surgical treatment in the Heart Institute of São Paulo. A right anterolateral thoracotomy approach associated with aortic cannulation was used for CPB. Eighty (80%) patients had rheumatic disease and 84 (84%) patients presented functional class III or IV. Were performed 45 (45%) comissurotomies, 38 (38%) valve repairs, 7(7%) mitral valve replacements, seven (7%) recomissurotomies and three (3%) prosthesis replacement. Sparing surgery was performed in 90 (90%) patients. The average CPB and clamp time were 57 ± 27 min e 39 ± 19 min, respectively. There were no in-hospital death, reoperation due to bleeding and convertion to sternotomy. Introperative complications were related to heart harvest (5%), especially in reoperations (3%). The most important complications in postoperative period were related to pulmonary system (11%), followed by atrial fibrilation (10%) but without major systemic repercussions. The mean inhospital length of stay was 8 ± 3 days. Follow-up was 6.038 patients/month. Actuarial survival was 98.0 ± 1.9% and freedom from reoperation was 81.4 ± 7.8% in 180 months. The right anterolateral thoracotomy associated with aortic cannulation in mitral valve surgery is a simple technique, reproducible and safety.

The preferred surgical approach for systemic-pulmonary shunts has changed from thoracotomy to sternotomy in our institution, to concomitantly manage the ductus arteriosus during surgery. The purpose of this study was to compare the outcomes of systemic-pulmonary shunts for neonates with functionally univentricular hearts based on surgical approach. Fifty-two neonates with functionally univentricular hearts underwent systemic-pulmonary shunt via sternotomy (n = 28) or thoracotomy (n = 24). Patient characteristics, achievement rates of right heart bypass, and survival rates were compared for the different approaches. Prenatal diagnosis was made more common in the sternotomy group (p = 0.006). The shunt was placed more centrally in the sternotomy group. The ductus arteriosus was ligated or banded in most patients in the sternotomy group (26/28) and in a few patients in the thoracotomy group (6/24). Frequency of ductal management in the early postoperative phase was not different between the groups (21 vs 25 %), but three new incisions had to be made in the thoracotomy group. No differences were seen in the achievement rates of bidirectional cavopulmonary shunts (86 vs 87 % at 10 months of age) and total cavopulmonary connection (81 vs 81 % at 2 years of age), or in the survival rates (92 vs 96 % at 8 years). There were no differences in short- and long-term outcomes between the groups. The sternotomy approach might be preferable in the current era of prenatal diagnosis, to allow simultaneous duct management during systemic-pulmonary shunt surgery, particularly in patients with large ducts associated with functionally univentricular hearts.

The management of newborns with esophageal atresia (EA) and right aortic arch (RAA) is still an unsolved problem. This study provides a systematic review of epidemiology, diagnosis, management and short-term results of children with EA and RAA. The PubMed database was searched for original studies on children with EA and RAA. In each study, data were extracted for the following outcomes: number of patients, associated anomalies, type of surgical repair, morbidity and mortality rate. Eight studies were selected, including 54 patients with EA and RAA. RAA was encountered in 3.6% of infants. Preoperative detection of RAA was reported in 7 of them. In these patients, primary anastomosis was achieved through the right approach in 3 (thoracotomy in 2 and thoracoscopy in 1) while the left approach was the primary choice in 4 (thoracotomy in 2 and thoracoscopy in 2). No significant differences were found between the right and left approaches with regard to leaks (P=0.89), strictures (P=1) or mortality (P=1). In 47/54 patients (87%) RAA was noted during right thoracotomy, and primary anastomosis was achieved through the same approach in 29 (61.7%); conversion to other approaches (left thoracotomy or esophageal substitution) was performed in 15 children (38.3%). No significant differences were found between primary left thoracotomy (LT) and LT after RT with regard to leaks (P=0.89), strictures (P=1) or mortality (P=1). Skills and preferences of the surgeon still guide the choice of surgical approach even when preoperatively faced with RAA. A multicenter, prospective randomized study is strongly required.

Objective To determine whether an acupuncture technique specially developed for a surgical oncology population (intervention) reduces pain or analgesic use after thoracotomy compared to a sham acupuncture technique (control). Methods One hundred and sixty two cancer patients undergoing thoracotomy were randomized to group A) preoperative implantation of small intradermal needles which were retained for 4 weeks or B) preoperative placement of sham needles at the same schedule. Numerical Rating Scale (NRS) of pain and total opioid use we evaluated during the in-patient stay; Brief Pain Inventory (BPI) and Medication Quantification Scale (MQS) were evaluated after discharge up to 3 months after the surgery. Results The principal analysis, a comparison of BPI pain intensity scores at the 30 day follow-up, showed no significant difference between the intervention and control group. Pain scores were marginally higher in the intervention group 0.05 (95% C.I.: 0.74, -0.64; p=0.9). There were also no statistically significant differences between groups for secondary endpoints, including chronic pain assessments at 60 and 90 days, in-patient pain, and medication use in hospital and after discharge. Conclusion A special acupuncture technique as provided in this study did not reduce pain or use of pain medication after thoracotomy more than a sham technique. PMID:19114190

The objective is to study the effects of flurbiprofen axetil (FA) with fentanyl together in postoperative controlled intravenous analgesia (PCIA) on pain intensity, cytokine levels in peripheral blood and adverse reactions of thoracotomy patients. Fifty thoracotomy patients were divided into a FA and a control group, each with 25 cases. Postoperative analgesia was administered in the two groups using PCIA. The pressing times of analgesia pump, the visual analog scale (VAS) scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery and the incidence of adverse drug reactions were recorded. Levels of IL-1β, IL-6, IL-8, IL-2, and TNF-α in peripheral blood were determined before the administration of FA (T0), and at 24 h (T1), 48 h (T2), 72 h (T3) after surgery. The analgesia pump pressing times in the FA group was less than that of the control group. The VAS scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery, were statistically less than those of control group. The incidence rate of nausea and vomiting was insignificantly different between the two groups. Administration of FA together with PCIA in thoracotomy patients can improve postoperative analgesia.

The choice of optimal operative access technique for mechanical circulatory support device implantation ensures successful postoperative outcomes. In this study, we retrospectively evaluated the median sternotomy and lateral thoracotomy incisions for placement of the Cleveland Clinic continuous-flow total artificial heart (CFTAH) in a bovine model. The CFTAH was implanted in 17 calves (Jersey calves; weight range, 77.0-93.9 kg) through a median sternotomy (n = 9) or right thoracotomy (n = 8) for elective chronic implantation periods of 14, 30, or 90 days. Similar preoperative preparation, surgical techniques, and postoperative care were employed. Implantation of the CFTAH was successfully performed in all cases. Both methods provided excellent surgical field visualization. After device connection, however, the median sternotomy approach provided better visualization of the anastomoses and surgical lines for hemostasis confirmation and repair due to easier device displacement, which is severely limited following right thoracotomy. All four animals sacrificed after completion of the planned durations (up to 90 days) were operated through full median sternotomy. Our data demonstrate that both approaches provide excellent initial field visualization. Full median sternotomy provides larger viewing angles at the anastomotic suture line after device connection to inflow and outflow ports.

Pectoral Nerves Block (PECS) and Serratus Plane Block (SPB) have been used to treat persistent post-surgical pain after breast and thoracic surgery; however, they cannot block the internal mammary region, so a residual pain may occur in that region. Parasternal block (PSB) and Thoracic Transversus Plane Block (TTP) anaesthetize the anterior branches of T2-6 intercostal nerves thus they can provide analgesia to the internal mammary region. We describe a 60-year-old man suffering from right post-thoracotomy pain syndrome with residual pain located in the internal mammary region after a successful treatment with PECS and SPB. We performed a PSB and TTP and hydrodissection of fascial planes with triamcinolone and Ropivacaine. Pain disappeared and the result was maintained 3 months later. This report suggests that PSB and TTP with local anaesthetic and corticosteroid with hydrodissection of fascial planes might be useful to treat a post thoracotomy pain syndrome located in the internal mammary region. The use of Transversus Thoracic Plane and Parasternal Blocks and fascial planes hydrodissection as a novel therapeutic approach to treat a residual post thoracotomy pain syndrome even when already treated with Pectoral Nerves Block and Serratus Plane Block. © 2018 European Pain Federation - EFIC®.

Objectives Transcutaneous electrical nerve stimulation has been used to control post-thoracotomy pain, with conflicting results. We aimed to assess its efficacy on post-thoracotomy pain and early complications. Methods Between January 2012 and December 2014, 87 patients underwent a standard posterolateral thoracotomy and were randomized in 2 groups: group T was 43 patients who had transcutaneous electrical nerve stimulation and group C was 44 patients who had placebo stimulation with an inoperative device. Pain score was measured using a visual analogue scale ranging from 0 to 10. The frequency of the device was set at 100 Hz and pulse width at 100 ms. Results There were no statistically significant differences in the demographic characteristics of the 2 groups, and there was no difference in the duration of hospitalization (4.74 ± 1.6 vs. 5.23 ± 1.5 days; p = 0.06). Postoperative pain scores of the two groups showed that on postoperative day 0, 1, and 2, the mean pain scores of group T were significantly lower ( p = 0.001, p < 0.001, and p = 0.003). There were no significant differences in early complications or surgical technique. Conclusion We concluded that electrical stimulation is a safe and effective adjunctive therapy for acute post-thoracotomy pain control. However, it does not affect the duration of hospitalization or early pulmonary complications.

To compare the postoperative recovery of patients with superior sulcus tumors (Pancoast tumors) following conventional open surgery vs. a hybrid video-assisted and limited open approach (VALO). The subjects of this retrospective study were 20 patients we operated on to resect a Pancoast tumor. All patients received induction chemo-radiation followed by surgery, performed via either a conventional thoracotomy approach (n = 10) or the hybrid VALO approach (n = 10). In the hybrid VALO group, lobectomy and internal chest wall preparation were performed using a video technique, with rib resection and specimen removal through a limited incision. There was no mortality in either group. Two patients from the thoracotomy group required mechanical ventilation, but there was no major morbidity in the hybrid VALO group. The operative times were similar for the two procedures. The average length of hospital stay was shorter and the average pain scores were significantly lower in the hybrid VALO group. The incidence of chronic pain was 10 % in the hybrid VALO group vs. 50 % in the thoracotomy group. Hybrid VALO resection of Pancoast tumors is feasible and safe, resulting in faster patient recovery and a significantly lower incidence of severe chronic pain than open thoracotomy. We conclude that centers experienced with video-assisted lobectomy should consider hybrid VALO surgery as the procedure of choice for Pancoast tumors.

This study examined the hypothesis that ipsilateral upper extremity elevation for muscle-sparing thoracotomy procedures contributes to the postoperative shoulder pain. Prospective observational study. Medical center. ASA physical status 1-2 patients undergoing elective lung surgeries including pneumonectomy, lobectomy, and segmentectomy performed through either the anterolateral approach or video-assisted thoracotomy surgery. Postoperative observation of ipsilateral shoulder pain. Postoperative examinations of sites of shoulder pain (clavicle, anterior, lateral,or posterior aspect of acromion, posterior neck, supraspinatus, infraspinatus, and these entire areas) with or without trigger points, visual analog scale score of wound pain, and requested counts of analgesics. The number of patients who suffered from postoperative shoulder pain was 37 of 70 (52.9%). Demographic data, anterolateral/VATS ratio, VAS scores, and requested counts of rescue analgesics requirement were similar in the groups of patients with and without postoperative shoulder pain. The segmentectomy caused a significantly higher incidence of postoperative shoulder pain compared with other procedures (p < 0.05). The supra- and infraspinatus were significantly higher areas of painful regions compared to the other sites. The 16 of 37 patients (43.2%) with shoulder pain showed defined trigger points in their painful areas. These results supported the hypothesis that myofascial involvement contributed, to some extent, to shoulder pain after muscle-sparing thoracotomy with ipsilateral upper extremity elevation.

Learning Curve of a Young Surgeon's Video-assisted Thoracic Surgery Lobectomy during His First Year Experience in Newly Established Institution

PubMed Central

Ahn, Hyo Yeong; Kim, Min Su

2012-01-01

Background The purpose of this paper is to present a guideline for beginning video-assisted thoracic surgery (VATS) lobectomy to junior surgeons, and to review the first year experience of a new surgeon performing VATS lobectomies who had not performed a VATS lobectomy unassisted during his training period. Materials and Methods A young surgeon opened a division of general thoracic surgery at a medical institution. The surgeon had performed about 100 lobectomies via conventional thoracotomy during his training period, but had never performed a VATS lobectomy unassisted while under the supervision of an expert. After opening the division of general thoracic surgery, the surgeon performed a total of 38 pulmonary lobectomies for various pulmonary diseases from March 2009 to February 2010. All data were collected retrospectively. Results There were 14 lobectomies via thoracotomy, 14 VATS lobectomies, and 10 cases of attempted VATS lobectomies that were converted to open thoracotomies. The number of VATS lobectomies increased from the second quarter (n=0) to the third quarter (n=5). The lobectomies that were converted from VATS into thoracotomies decreased from the second quarter (n=5) to the third quarter (n=1) (p=0.002). Conclusion It can take 6 months for young surgeons without experience in VATS lobectomy in their training period to be able to reliably perform a VATS lobectomy. PMID:22708084

The choice of analgesia in the management of post-thoracotomy pain remains controversial. Although several alternative forms of post-thoracotomy analgesia exist, all have their disadvantages. Cryoanalgesia, localized freezing of intercostal nerves, has been reported to have variable effectiveness and an incidence of long-term cutaneous sensory changes. We carried out an animal study to assess the reversibility of histological changes induced by cryoanalgesia and a prospective randomized trial to compare the effectiveness of cryoanalgesia with conventional analgesia (parenteral opiates). In six anaesthetized dogs, intercostal nerves were exposed to a varying duration of cryo-application (30, 60, 90 and 120 s). The nerves were biopsied and examined histologically at regular intervals over the following 6 months. In the clinical study, 200 consecutive patients undergoing thoracotomy were randomized to cryoanalgesia and conventional (parenteral opiates) analgesia groups. Postoperative pain scores, respiratory function tests and use of opiate analgesia were measured for the two groups. Following application of the cryoprobe, degeneration and fragmentation of the axons was evident with associated inflammatory changes. As the endoneurium remained intact, axonal regeneration took place after the resolution of axonal swelling. Over the course of weeks, recovery of the intercostal nerve occurred and was complete after 1 month for the 30 and 60 s groups. For nerves exposed to longer durations of cryoanalgesia, the time taken for complete recovery was proportionally increased. Clinically, there was a statistically significant (P<0.05) improvement in postoperative pain scores and use of opiate analgesia and an improvement (P>0.05) in respiratory function tests for patients in the cryoanalgesia group. The previously suggested cutaneous sensory changes resolved within 6 months with complete restoration of function. We suggest that cryoanalgesia be considered as a simple, inexpensive, long-term form of post-thoracotomy pain relief, which does not cause any long-term histological damage to intercostal nerves.

Superior vena caval pressure elevation causes pleural effusion formation in sheep.

1988-09-01

The effect of superior vena caval pressure (SVCP) elevation on the formation of pleural effusions (PE) was studied in sheep. Through a right thoracotomy, a Silastic cuff was placed around the superior vena cava. Catheters for monitoring SVCP and pulmonary artery pressure (PAP) were also placed. After a 1- to 3-wk recovery period, we measured the SVCP, PAP, cardiac output, and plasma protein concentration (Cp). We then elevated the SVCP to various levels from base line [5.3 +/- 2.6 (SD) mmHg] to 33 mmHg. The cardiac output, PAP, and Cp were remeasured 1-2 h and 24 h after SVCP elevation. At the end of the 24-h period, the animals were killed. The PE volume and pleural fluid protein concentration (Cpl) were measured, and the Cpl/Cp was calculated. PE generally did not occur until the SVCP was elevated above 15 mmHg. To study the effect of the thoracotomy on the subsequent pleural effusion, we studied six additional sheep in which we did not perform a thoracotomy. In these animals, the SVCP was elevated to between 5 and 28 mmHg for 24 h by use of a 16-Fr balloon catheter placed via a left external jugular vein and a right carotid-external jugular shunt. We found that the PE volume, for a given SVCP elevation, was similar to that present in sheep that received a thoracotomy. For all sheep the volume of PE was related to SVCP by the equation PE (ml) = 0.24e0.26SVCP, r = 0.85. In the sheep without a thoracotomy, Cpl/Cp rose with increasing volume of PE. Our data demonstrate that elevation of SVCP greater than 15 mmHg for 24 h results in the formation of PE. The rise in Cpl/Cp with PE volume suggests that filtration through the pleural vessels is not the major contributor to PE formation.

Spontaneous Chronic Pain After Experimental Thoracotomy Revealed by Conditioned Place Preference: Morphine Differentiates Tactile Evoked Pain From Spontaneous Pain.

Chronic pain after surgery limits social activity, interferes with work, and causes emotional suffering. A major component of such pain is reported as resting or spontaneous pain with no apparent external stimulus. Although experimental animal models can simulate the stimulus-evoked chronic pain that occurs after surgery, there have been no studies of spontaneous chronic pain in such models. Here the conditioned place preference (CPP) paradigm was used to reveal resting pain after experimental thoracotomy. Male Sprague Dawley rats received a thoracotomy with 1-hour rib retraction, resulting in evoked tactile hypersensitivity, previously shown to last for at least 9 weeks. Intraperitoneal injections of morphine (2.5 mg/kg) or gabapentin (40 mg/kg) gave equivalent 2- to 3-hour-long relief of tactile hypersensitivity when tested 12 to 14 days postoperatively. In separate experiments, single trial CPP was conducted 1 week before thoracotomy and then 12 days (gabapentin) or 14 days (morphine) after surgery, followed the next day by 1 conditioning session with morphine or gabapentin, both versus saline. The gabapentin-conditioned but not the morphine-conditioned rats showed a significant preference for the analgesia-paired chamber, despite the equivalent effect of the 2 agents in relieving tactile allodynia. These results show that experimental thoracotomy in rats causes spontaneous pain and that some analgesics, such as morphine, that reduce evoked pain do not also relieve resting pain, suggesting that pathophysiological mechanisms differ between these 2 aspects of long-term postoperative pain. Perspective: Spontaneous pain, a hallmark of chronic postoperative pain, is demonstrated here in a rat model of experimental postthoracotomy pain, further validating the use of this model for the development of analgesics to treat such symptoms. Although stimulus-evoked pain was sensitive to systemic morphine, spontaneous pain was not, suggesting different mechanistic underpinnings. Copyright © 2015 American Pain Society.

Post-thoracotomy pain is very severe and may cause pulmonary complications. Thoracic epidural analgesia can greatly decrease the pain experience and its consequences. However, finding new methods to decrease the amount of administered opioids is an important issue of research. We aimed to evaluate the effect of adding epidural magnesium sulfate to bupivacaine and morphine on pain control and the amount of opioid consumption after thoracotomy. Eighty patients undergoing thoracotomy at a tertiary cardiothoracic referral centre were enrolled in a randomized, double-blind trial. Patients were randomly allocated to two groups. Bupivacaine (12.5 mg) plus morphine (2 mg) were administered epidurally to all patients at the end of operation. Patients in magnesium (Mg) group received epidural magnesium sulfate (50 mg) and patients in control (C) group received normal saline as an adjuvant. Visual analogue scale (VAS) score and the amount of morphine consumption were measured during 24 hr post-operation. Thirty-nine patients in Mg group and 41 patients in C group completed the study. Patients in Mg group had significantly less VAS score at recovery time (p<0.05), 2 h (p<0.01) and 4 hr (p<0.05) after surgery. The patients-controlled analgesia pump was started earlier in C group than in Mg group (p< 0.05). The amount of morphine needed in Mg group was significantly lower than C group (5.64±1.69 mg/24 hr versus 8.44±3.98 mg/24 hr; P<0.001). Pruritus was seen in C group (9.7%) and absent in Mg group (p<0.05). Co-administration of magnesium sulfate with bupivacaine and morphine for thoracic epidural analgesia after thoracotomy leads to reduction in post-operative pain score and the need for opioid administration.

To present a case of bilateral parapneumonic effusions in a child with Pneumococcal pneumonia and bacteraemia managed aggressively with early thoracotomies. The literature from peer reviewed journals is summarized and the different management strategies are discussed. Articles and reviews from peer reviewed journals on the management of empyema in children and adults. Staging of parapneumonic pleural effusions is difficult to assess clinically and radiologically. Most cases can be successfully managed with simple chest tube drainage, plus appropriate antibiotic therapy. However, based on the available evidence for children, thoracotomy with decortication and direct drainage may provide the most effective treatment in terms of length of hospital stay and duration of chest tube insertion, when compared with video assisted thoracoscopic surgery (VATS) or chest tube drainage, with or without intrapleural fibrinolytic therapy. More conservative approaches to treatment of empyema may be appropriate initially to avoid the cosmetic and other disadvantages of thoracotomy. However, delayed surgical drainage increases morbidity and may potentially increase mortality.

Simulation trainer for practicing emergent open thoracotomy procedures.

An emergent open thoracotomy (OT) is a high-risk, low-frequency procedure uniquely suited for simulation training. We developed a cost-effective Cardiothoracic (CT) Surgery trainer and assessed its potential for improving technical and interprofessional skills during an emergent simulated OT. We modified a commercially available mannequin torso with artificial tissue models to create a custom CT Surgery trainer. The trainer's feasibility for simulating emergent OT was tested using a multidisciplinary CT team in three consecutive in situ simulations. Five discretely observable milestones were identified as requisite steps in carrying out an emergent OT; namely (1) diagnosis and declaration of a code situation, (2) arrival of the code cart, (3) arrival of the thoracotomy tray, (4) initiation of the thoracotomy incision, and (5) defibrillation of a simulated heart. The time required for a team to achieve each discrete step was measured by an independent observer over the course of each OT simulation trial and compared. Over the course of the three OT simulation trials conducted in the coronary care unit, there was an average reduction of 29.5% (P < 0.05) in the times required to achieve the five critical milestones. The time required to complete the whole OT procedure improved by 7 min and 31 s from the initial to the final trial-an overall improvement of 40%. In our preliminary evaluation, the CT Surgery trainer appears to be useful for improving team performance during a simulated emergent bedside OT in the coronary care unit.

Traumatic blunt cardiac injuries have a high mortality rate, and prompt diagnosis and treatment can be lifesaving in cardiac tamponade. A 62-year-old man was transferred to the emergency department after a motor vehicle accident. He was hemodynamically unstable. A focused assessment with sonography in trauma (FAST) showed pericardial fluid with right ventricular collapse consistent with cardiac tamponade in the subxiphoid view. He collapsed despite a subxiphoid pericardiotomy. Owing to the ongoing hemodynamic instability, we performed a left anterolateral thoracotomy. Direct incision of the pericardium showed blood and clots within the pericardial space, indicating hemopericardium. The heart stroke and hemodynamic status recovered on removing the clot. Although the physical findings of cardiac tamponade are not always apparent in life-threatening acute cardiac tamponade after blunt trauma, FAST is a reliable tool for diagnosing and following cardiac tamponade. A median sternotomy is a standard approach for evaluating cardiac injury in hemodynamically stable patients with or without cardiopulmonary bypass. However, a left anterior thoracotomy was the fastest, simplest life-saving procedure considering the need for open-chest cardiac massage given our patient's life-threatening condition. A prompt diagnosis using FAST and treatment can be lifesaving in traumatic acute cardiac tamponade. A pericardiotomy via a thoracotomy is mandatory for lifesaving cardiac decompression in acute traumatic cardiac tamponade in cases of ineffective drainage due to clot formation within the pericardial space.

Paraplegia is an uncommon yet devastating complication following thoracotomy, usually caused by compression or ischemia of the spinal cord. Ischemia without compression may be a result of global ischemia, vascular injury and other causes. Epidural anesthesia has been implicated as a major cause. This report highlights the fact that perioperative cord ischemia and paraplegia may be unrelated to epidural intervention. A 71-yr-old woman was admitted for a left upper lobectomy for resection of a non-small cell carcinoma of the lung. The patient refused epidural catheter placement and underwent a left T5-6 thoracotomy under general anesthesia. During surgery, she was hemodynamically stable and good oxygen saturation was maintained. Several hours following surgery the patient complained of loss of sensation in her legs. Neurological examination disclosed a complete motor and sensory block at the T5-6 level. Magnetic resonance imaging (MRI) revealed spinal cord ischemia. The patient received iv steroid treatment, but remained paraplegic. Five months following the surgery there was only partial improvement in her motor symptoms. A follow-up MRI study was consistent with a diagnosis of spinal cord ischemia. In this case of paraplegia following thoracic surgery for lung resection, epidural anesthesia/analgesia was not used. The MRI demonstrated evidence of spinal cord ischemia, and no evidence of cord compression. This case highlights that etiologies other than epidural intervention, such as injury to the spinal segmental arteries during thoracotomy, should be considered as potential causes of cord ischemia and resultant paraplegia in this surgical population.

To date, no long-term clinical data have been published in patients undergoing a nonthoracotomy approach to cardioverter-defibrillator system implantation. In the present report, 189 consecutive patients prospectively underwent a standardized approach to cardioverter-defibrillator system implantation in which the nonthoracotomy configurations were tested first. If satisfactory defibrillation thresholds were not obtained, thoracotomy was performed during the same intraoperative session. A nonthoracotomy system was successfully implanted in 149 of 189 patients (79%), with a higher success rate (90%) observed in patients who had more recent implantations. The overall rate of complications associated with these systems was low (11%). Over a mean follow-up of 12.5 +/- 9.3 months, 17 patients (9%) died. Three-year total, cardiac, and sudden death-free actuarial survival for all patients was 83 +/- 11%, 88 +/- 7%, and 94 +/- 2%, respectively. Three-year sudden death-free actuarial survival was higher in the nonthoracotomy than in the thoracotomy patients (97 +/- 2% vs 87 +/- 6%, p = 0.047), although total survival was similar (77 +/- 11% vs 83 +/- 7%, p = 0.77). These data suggest that a majority of patients (> 80%) requiring a cardioverter-defibrillator system can undergo implantation using a nonthoracotomy approach. Patients receiving nonthoracotomy systems have 3-year outcomes comparable to those implanted via thoracotomy. If these results are maintained, a nonthoracotomy approach will supplant thoracotomy-implanted systems as the preferred method because of the simpler implant procedure and lower overall cost involved.

We retrospectively studied the surgical treatment for pulmonary metastases from colon and rectal cancer. A total of 24 patients (9 males and 15 females; mean age 61 years) underwent 29 thoracotomies for metastatic colon carcinoma, while 22 patients (16 males and 6 females; mean age 63 years) underwent 29 thoracotomies for metastatic rectal cancer. The median interval between the primary procedure and lung resection for metastases was 26 months in the patients with colon carcinoma and 32 months in the patients with rectal cancer. In the patients with colon carcinoma, 16 underwent wedge resection or segmentectomy (including 4 video-assisted procedures) and 13 (54%) underwent lobectomy or pneumonectomy. In the patients with rectal cancer, 15 underwent wedge or segmentectomy (including 1 video-assisted procedure), 13 (59%) underwent lobectomy or pneumonectomy, and 1 underwent exploratory thoracotomy. All procedures except exploratory thoracotomy were curative operations. There was no mortality. Overall 5-year survival was 56% (n=46). Five-year survival was 65% for patients with colon metastases (n=24) and 45% for patients with rectal metastases (n=22), and there was no significant difference. Recurrent sites were 4 lungs (36%), 4 livers (36%), 1 bone, 1 uterus, and 1 peritoneum in patients with colon carcimoma, and 10 lungs (43%), 5 brains (22%), 3 livers (13%), 1 bone, and 1 vagina in patients with rectal cancer. Pulmonary resection for metastases from colon carcinoma may have better prognosis than that from rectal cancer. However, further investigation may be required to obtain convincing conclusions.

Surgical closure of persistent arterial duct with minimal invasive anterior thoracotomy: an alternative technique.

Surgical approach for persistent ductus arteriosus ligation is typically a left lateral thoracotomy opening the pleural-space with left lung retraction. We describe an alternative approach, with a minimally invasive anterior parasternal incision. This is particularly adapted to preterm infants weighing less than 1.5 kg. This approach ensures a good exposure of vessels. We believe that it is safe, reliable and reproducible. The learning curve should not be an issue for surgeons used to manage low weight patients.

Spontaneous hemothorax is a rare condition. Its causes are multiple but sometimes they remain unknown. In some patients, thoracotomy may be the only means to determine hemothorax origin. Vasculitis have not been reported as a common cause of spontaneous hemothorax. Pregnancy does not appear to have causal or aggravating effect on spontaneous hemothorax or on vasculitis. We here report the peculiar case of a young patient presenting during pregnancy with spontaneous hemothorax secondary to Wegener's vasculitis. The latter was diagnosed by pleural biopsy performed during exploratory thoracotomy and confirmed by ANCA assays.

Transcutaneous electrical nerve stimulation (TENS) is commonly used to treat musculoskeletal pain, but it may also be indicated for postoperative analgesia. The objective of this study was to evaluate the analgesic effects of TENS on post-thoracotomy. Thirty patients between 18 and 60 years of age undergoing thoracotomy for lung cancer resection on the second postoperative day were included in this study. Patients were divided into two groups (G1 and G2). G1 patients were treated with TENS; and in G2 (without TENS) electrodes were placed but the equipment was not turned on. TENS was maintained for one hour. The visual analogue scale was used to evaluate the analgesic effects on three moments: before TENS (M0), immediately after TENS (M1), and one hour later (M2), with the patient at rest, elevation of the upper limbs, change in decubitus, and coughing. The intensity of pain at rest was higher in G2 immediately after TENS, but not one hour after the procedure. There was no difference between both groups with elevation of the upper limbs, decubitus change, and coughing. With the use of TENS for one hour on the second post-thoracotomy day in patients who received fentanyl (50 μg) associated with bupivacaine (5 mL), a reduction in pain intensity was observed at rest immediately after TENS; with elevation of the upper limbs, change in decubitus, and coughing, a reduction in pain severity was not observed.

Blunt main stem bronchial injuries are rare but potentially life-threatening injuries in clinical. The aim of this study was to sum up the experience on diagnosis and treatment of blunt main stem bronchial injuries. This report retrospective1y analyzed eight cases of main stem bronchial injuries induced by blunt chest trauma between 2013 and 2016 in Tangdu Hospital, Fourth Military Medical University. There were eight patients, including four men and four women. The definitive diagnosis was confirmed by fibrobronchoscopy. Mean time between injury and treatment in our hospital was 4.25 days (range, 1-12 days). Mean length of airway tear was 1.04 cm (range, 0.5-2 cm). In four patients there was an injury to the left main stem bronchus, in three patients to the right main stem bronchus and in one patient to the ambilateral main stem bronchus. Emergent operation was performed in two patients and elective operation in six patients. End to end bronchial anastomosis was performed via right thoracotomy in two patients and via left thoracotomy in three patients, and primary repair was performed via right thoracotomy in two patients and via left thoracotomy in the remaining one patient. There was no death in this group. Seven patients had no complications and were able to take part in normal activities. One patient suffered from anastomotic stricture after operation was healed by granulation tissue resection and cryotherapy under fibrobronchoscopy. Fibrobronchoscopy is able to define the blunt main stem bronchial injuries precisely and surgical approach is the preferred method for patients with these life-threatening complications.

New symptom onset of respiratory distress without other cause, and new hemi-diaphragmatic elevation on chest radiography postcardiotomy, are usually adequate for the diagnosis of phrenic nerve paresis. The symptom severity varies (asymptomatic state to severe respiratory failure) depending on the degree of the lesion (paresis vs. paralysis), the laterality (unilateral or bilateral), the age, and the co-morbidity (respiratory, cardiac disease, morbid obesity, etc). Surgical treatment (hemi-diaphragmatic plication) is indicated only in the presence of symptoms. The established surgical treatment is plication of the affected hemidiaphragm which is generally considered safe and effective. Several techniques and approaches are employed for diaphragmatic plication (thoracotomy, video-assisted thoracoscopic surgery, video-assisted mini-thoracotomy, laparoscopic surgery). The timing of surgery depends on the severity and the progression of symptoms. In infants and young children with postcardiotomy phrenic nerve paresis the clinical status is usually severe (failure to wean from mechanical ventilation), and early plication is indicated. Adults with postcardiotomy phrenic nerve paresis usually suffer from chronic dyspnoea, and, in the absence of respiratory distress, conservative treatment is recommended for 6 months -2 years, since improvement is often observed. Nevertheless, earlier surgical treatment may be indicated in non-resolving respiratory failure. We present early (25th day postcardiotomy) right hemi-diaphragm plication, through a video assisted mini-thoracotomy in a high risk patient with postcardiotomy phrenic nerve paresis and respiratory distress. Early surgery with minimal surgical trauma, short operative time, minimal blood loss and postoperative pain, led to fast rehabilitation and avoidance of prolonged hospitalization complications. The relevant literature is discussed. PMID:23304442

Videothoracoscopic resection for lung cancer: moving towards a “standard of care”

PubMed Central

2016-01-01

Videothoracic surgery for lung cancer is now an established practice but there is a division of opinion between surgeons whose aim is to spare all patients a thoracotomy and those who have not adopted videoscopic methods for routine lobectomy. The latter remain in the majority; most patients at present have a thoracotomy. Surgeons from Europe and America met in Catania, Sicily at the 3rd Mediterranean Symposium on Thoracic Surgical Oncology to explore the evidence and the routes to making videothoracoscopic surgery a standard of care. Evidence from one completed randomized controlled trial (RCT) and several propensity score matching studies indicate that less invasive surgery is at least as safe as thoracotomy. By the accepted standards of an oncological lobectomy which include clearance of the primary cancer and the intended lymphadenectomy or sampling, the operations are equivalent. Clinical effectiveness in achieving long-term cancer free survival is likely. However, the co-existance of videothoracoscopy has encouraged smaller non-muscle cutting incisions and the avoidance of rib spreading, narrowing whatever gap there may have been in terms of the patients’ experience.

To evaluate the quality of postoperative pain relief during the first 3 days after surgery and to evaluate with the incidence of persistent pain at 6 months after surgery. Retrospective single-center audit. University hospital. Five hundred four patients who underwent thoracotomy. Review of patient records, questionnaire, and telephone review. Of the 364 survivors, 306 were contacted. Five or more episodes of severe pain (numerical rating scale >6/10 at rest or movement) during the first 72 hours after surgery occurred in 133 patients. Persistent postsurgical pain at 6 months was present in 82% (109/133) of these patients. Patient satisfaction with acute postoperative pain management was excellent (36%), good (43%), and fair or poor (21%).The incidence of postthoracotomy pain was 56% (mild 32%, moderate 18%, and severe 6%). Poorly controlled acute postoperative pain correlated with persistent postsurgical pain at 6 months. In view of such a high incidence in thoracotomy patients, preventative strategies assume great significance. Copyright © 2016 Elsevier Inc. All rights reserved.

Left heart pacing lead implantation using subxiphoid videopericardioscopy.

Zenati, Marco A; Bonanomi, Gianluca; Chin, Albert K; Schwartzman, David

2003-09-01

Recent clinical data support the utility of left heart pacing. The transvenous approach for left heart pacing lead implantation is imperfect. A direct epicardial approach may have advantages, but heretofore its utility has been limited because of the requirement for thoracotomy. We sought to examine the feasibility of a method for epicardial lead implantation that did not require thoracotomy. In five large swine, percutaneous access to the epicardium was achieved with subxiphoid videopericardioscopy, using a device that marries endoscopy with a port through which pacing leads could be introduced. In each animal, standard, active fixation pacing leads were implanted onto the left atrium and ventricle. The atrial lead was implanted at the base of the appendage. The ventricular lead was implanted on the anterior, lateral, and inferior walls. Continuous direct visualization of the epicardium provided guidance for lead localization and fixation, including avoidance of complications such as trauma to epicardial coronary vessels. Capture thresholds were uniformly low. Postmortem examination demonstrated anatomically accurate, uncomplicated lead fixation. Using subxiphoid videopericardioscopy, uncomplicated, anatomically accurate left heart epicardial pacing lead implantation can be achieved without thoracotomy.

To review alternative surgical and anaesthetic options in the management of foreign bodies lodged in the tracheobronchial tree in children aged below 10 years. A five year retrospective secondary data analysis. Three hospitals based in Eldoret Municipality, Kenya. Outcome variables included morbidity and mortality. Of the thirty two children studied, 74.1% had bronchoscopy and 25.9% thoracotomy. The overall mortality rate was 3.3%. Foreign bodies in the tracheo-bronchial tree are a major cause of morbidity and mortality in children aged below 10 years. In settings where appropriate equipment is inadequate, timely thoracotomy may be life saving.

2003-09-01

The therapeutic possibilities in veterinary cardiology have developed rapidly in the past few years. Whereas until recently cardiac intervention in dogs could only be performed by thoracotomy, new minimally invasive techniques are adopted. Procedures like balloondilatation of pulmonic stenosis, coil embolisation of patent ductus arteriosus, pacemaker implantation in symptomatic bradyarrhyhtmia, and palliative balloon pericardiotomy are becoming more and more established. These alternative interventional methods are attractive, because no postsurgical pain and no complications potentially associated with thoracotomy ensue. The knowledge of such new treatment modalities and particularly the indications for an intervention are prerequisites to apply them optimally and broadly.

Introduction In the last decade, video-assisted thoracoscopic surgery (VATS) lobectomy for non-small cell lung cancer (NSCLC) has had a major effect on thoracic surgery. Retrospective series have reported benefits of VATS when compared with open thoracotomy in terms of postoperative pain, postoperative complications and length of hospital stay. However, no large randomised control trial has been conducted to assess the reality of the potential benefits of VATS lobectomy or its medicoeconomic impact. Methods and analysis The French National Institute of Health funded Lungsco01 to determine whether VATS for lobectomy is superior to open thoracotomy for the treatment of NSCLC in terms of economic cost to society. This trial will also include an analysis of postoperative outcomes, the length of hospital stay, the quality of life, long-term survival and locoregional recurrence. The study design is a two-arm parallel randomised controlled trial comparing VATS lobectomy with lobectomy using thoracotomy for the treatment of NSCLC. Patients will be eligible if they have proven or suspected lung cancer which could be treated by lobectomy. Patients will be randomised via an independent service. All patients will be monitored according to standard thoracic surgical practices. All patients will be evaluated at day 1, day 30, month 3, month 6, month 12 and then every year for 2 years thereafter. The recruitment target is 600 patients. Ethics and dissemination The protocol has been approved by the French National Research Ethics Committee (CPP Est I: 09/06/2015) and the French Medicines Agency (09/06/2015). Results will be presented at national and international meetings and conferences and published in peer-reviewed journals. Trial registration number NCT02502318. PMID:28619764

OBJECTIVES Patients undergoing thoracotomy were studied to compare the effects of cryoanalgesia, combined with intravenous patient-controlled analgesia (IVPCA), against IVPCA alone during the four days following surgery. METHODS Fifty patients were randomized into two groups: an IVPCA group (n = 25) and an IVPCA-cryo group (n = 25). Subjective pain intensity was assessed on a verbal analogue scale at rest and during coughing. The intensity and the incidence of post-thoracotomy pain, numbness, epigastric distension and/or back pain, the analgesic requirements, as well as the blood gas values and respiratory function tests were evaluated up to the second postoperative (postop) month. Haemodynamic data and episodes of nausea and/or vomiting were recorded over the four postop days. RESULTS In the cryo group there was a statistically significant improvement in postop pain scores (P = 10–4), reduction in consumption of morphine (P = 10–4) and other analgesics (P = 10–4), optimization (less acidosis) of the pH values of blood gases (P < 0.015 over 72 hours postop and P < 0.03 on the first and second postop months), increase in systolic blood pressure (P < 0.05 over 96 hours postop), reduction in heart rate (P < 0.05 over 96 hours postop), increase in values of FEV1 (P < 0.02) and FVC (P < 0.05) at the first and second postop months, reduction in the incidence of nausea (0.05 < P < 0.1 over 18 hours postop), numbness, epigastric distension and back pain (P < 0.05 at days 5, 6, 7, 14, 30 and 60 following surgery). CONCLUSIONS We suggest that cryoanalgesia be considered as a simple, safe, inexpensive, long-term form of post-thoracotomy pain relief. Cryoanalgesia effectively restores FEV1 values at the second postop month. PMID:23424242

Introduction Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease with a fatal prognosis. The diagnosis is made on the basis of high-resolution computed tomography and histological examination in selected cases. Aim To determine the risk of complications of open lung biopsy performed in patients with IPF. Material and methods We performed a retrospective analysis of 51 patients who underwent diagnostic excision of pulmonary parenchyma due to IPF in the period 1995–2014. We assessed the complication rate, length of drainage, postoperative period and 30-day mortality. We compared the results of treatment in the groups of patients operated on with thoracotomy and videothoracoscopy. Results The mean age of patients was 58 (47% female, 53% male) forced vital capacity (FVC) was 81%, forced expiratory volume in 1 s (FEV1) was 80% and body mass index (BMI) was 27 kg/m2. Thoracotomies (lateral, muscle sparing or anterior) were performed in 20 patients between 1995 and 2012 and videothoracoscopy in 31 patients operated on in the years 2009–2014. Patients in study groups did not differ considering age (p = 0.40), gender (p = 0.81), FVC (p = 0.08), FEV1 (p = 0.13) or BMI (p = 0.75). Postoperative complications occurred in 3.9% of patients (atrial arrhythmia 1.9% and recurrent pneumothorax 1.9%) with equal incidence in both study groups (p = 0.75). Median stay after thoracotomy was 4 days while after videothoracoscopy it was 3 days (p = 0.04). Conclusions Open lung biopsy performed on patients with IPF is a safe procedure. Open lung biopsy performed through thoracotomy could be as safe as through VATS, however is characterized by longer postoperative stay. PMID:29354175

To determine the incidence of ipsilateral shoulder pain (ISP) with the therapeutic use of parecoxib compared with a placebo after thoracotomy. A prospective, randomized, double-blind, placebo-controlled trial. A tertiary-care university hospital. Adult patients undergoing an elective thoracotomy between June 2011 and February 2015. Patients were allocated randomly into the parecoxib group (n = 80) and the control group (n = 80). In the parecoxib group, 40 mg of parecoxib was diluted into 2 mL and given intravenously 30 minutes before surgery and then every 12 hours postoperatively for 48 hours. In the control group, 2 mL of normal saline was given to the patients at the same intervals. A numerical rating scale was used to assess the intensity of ISP at 2, 6, 12, 24, 48, 72, and 96 hours after surgery. Intravenous morphine (0.05 mg/kg) was used as the rescue medication for ISP during the 96-hour period. Baseline characteristics of patients in both groups were comparable. Patients in the parecoxib group had a significantly lower incidence of ISP, both overall (42.5% v 62.0%, p = 0.014) and of moderate-to-severe ISP when compared with the control group (26.2% v 49.4%, p = 0.003). Parecoxib reduced the risk of ISP by a statistically significant 32% (risk ratio, 0.68; 95% confidence interval, 0.50-0.93, p = 0.016). There were no significant differences in the occurrence of adverse effects between the groups. Intravenous parecoxib significantly can reduce the incidence and severity of ISP after thoracotomy.

The objective of this study was to assess the safety of general thoracic surgery in patients taking antiplatelet (clopidogrel) therapy. A prospective study was conducted of consecutive patients who underwent general thoracic surgery and who were taking clopidogrel perioperatively. They were matched using a propensity score from our prospective database of 11,768 patients. Intraoperative and postoperative outcomes were compared. Between January 2009 and April 2010 there were 33 patients on clopidogrel at the time of surgery and 132 controls. The most common procedures were thoracotomy with lobectomy in 11 patients (robotic in 1), video-assisted wedge resection in 6, mediastinoscopy in 4, and Ivor Lewis esophagogastrectomy in 2. Epidurals were not used. There was no intraoperative morbidity or bleeding in primary thoracotomy; however, 2 of the 4 patients who underwent redo thoracotomy had bleeding that required transfusions. None of the 8 patients receiving clopidogrel who had a coronary artery stent and underwent lobectomy had a perioperative myocardial infarction whereas 5 of the 14 control patients undergoing lobectomy who had a coronary artery stent did (P = .05). Otherwise, morbidity, mortality, and length of stay were no different. Patients who are receiving clopidogrel and who have a coronary artery stent placed can safely undergo general thoracic surgery. The widely held belief that surgery cannot be performed without bleeding is untrue. This new finding not only eliminates much of the preoperative dilemma posed by these patients but also may reduce their risk of a postoperative myocardial infarction. However, patients who require a redo thoracotomy may be at increased risk of bleeding. Copyright © 2010 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

Perioperative analgesia during thoracotomy is often achieved by combining paravertebral block (PVB) with general anesthesia (GA). Functional near-infrared spectroscopy (NIRS) can detect changes in cerebral oxygenation resulting from nociceptive stimuli in the awake state or under sedation. We used NIRS to measure changes in cerebral blood flow provoked by thoracotomy incision made under GA and determine how these changes were influenced by supplementation of GA with PVB. Thirty-four patients undergoing elective thoracotomy were enrolled. Patients were randomly assigned to a group receiving only GA, or GA combined with PVB (GA + PVB). Changes in cerebral oxygenated hemoglobin (ΔO 2 Hb), deoxygenated-Hb (ΔHHb), and total-Hb (ΔtotalHb) were evaluated by NIRS as surgery began. In the GA group, ΔO 2 Hb was significantly higher in the hemisphere contralateral to the side of surgery when the incision was made and 2 min after incision compared with the ipsilateral side (start of surgery, P < 0.01; 2 min, P < 0.05). In contrast, there were no significant changes in the ΔO 2 Hb at any of the time points in the GA + PVB group. Comparable with ΔO 2 Hb, the concentration of ΔtotalHb was significantly higher in the contralateral hemisphere in the GA group at the start of surgery (P < 0.05). Changes in the cerebral O 2 Hb concentration were detected by NIRS immediately after surgical incision under GA, but not in the presence of a PNB. NIRS could be used to monitor surgical pain. PVB inhibited changes in oxygenation induced by incision-provoked pain.

Video-assisted thoracic surgery for left upper lobectomy for complex lesions: how to extend the indication with optimal safety?

The feasibility of extending the VATS approach to locally advanced NSCLC has been described with good clinical outcome. These complex resections are still technically challenging and patient safety must remain the highest priority. In this article, we describe our routine VATS approach for left upper lobectomy in proximal, locally advanced lesions. Both surgical and anaesthesiology teams are trained during simulation sessions to respond rapidly in case of urgent thoracotomy. Encircling arterial and venous vessels allow control of inadvertent bleeding during difficult dissection. Also, whenever needed the double vessel control technique is a time saver waiting for conversion to thoracotomy.

Videothoracoscopy in Pleural Empyema Following Methicillin-Resistant Staphylococcus aureus (MRSA) Lung Infection

2009-01-01

Our study shows the different therapeutic procedures in 64 patients with pleural effusion due to MRSA pneumonia. The thoracostomy tube associated with pleural washing was decisive in 10 simple effusion patients. Video-assisted thoracic surgery allowed a complete resolution of the disease in 22 complex parapneumonic effusion patients. In 20 of 32 patients with frank pus in the pleural cavity, the videothoracoscopic insufflation of carbon dioxide (CO2) before thoracotomy facilitated the dissection of the lung tissue. In 12 patients, this approach was not applied because of cardiac insufficiency. Videothoracoscopy and decortication after thoracotomy ensured the recovery of functions. PMID:19649511

Robotic Lung Resection for Non-Small Cell Lung Cancer.

PubMed

Wei, Benjamin; Eldaif, Shady M; Cerfolio, Robert J

2016-07-01

Robotic-assisted pulmonary lobectomy can be considered for patients able to tolerate conventional lobectomy. Contraindications to resection via thoracotomy apply to patients undergoing robotic lobectomy. Team training, familiarity with equipment, troubleshooting, and preparation are critical for successful robotic lobectomy. Robotic lobectomy is associated with decreased rates of blood loss, blood transfusion, air leak, chest tube duration, length of stay, and mortality compared with thoracotomy. Robotic lobectomy offers many of the same benefits in perioperative morbidity and mortality, and additional advantages in optics, dexterity, and surgeon ergonomics as video-assisted thoracic lobectomy. Long-term oncologic efficacy and cost implications remain areas of study. Copyright © 2016 Elsevier Inc. All rights reserved.

The future of resuscitative endovascular balloon occlusion in combat operations.

Smith, Shane A; Hilsden, R; Beckett, A; McAlister, V C

2017-08-09

Damage control resuscitation and early thoracotomy have been used to increase survival after severe injury in combat. There has been a renewed interest in resuscitative endovascular balloon occlusion of the aorta (REBOA) in both civilian and military medical practices. REBOA may result in visceral and limb ischaemia that could be harmful if use of REBOA is premature or prolonged. The purpose of this paper is to align our experience of combat injuries with the known capability of REBOA to suggest an implementation strategy for the use of REBOA in combat care. It may replace the resuscitative effect of thoracotomy; can provide haemostasis of non-compressible torso injuries such as the junctional and pelvic haemorrhage caused by improvised explosive devices. However, prehospital use of REBOA must be in the context of an overall surgical plan and should be restricted to deployment in the distal aorta. Although REBOA is technically easier than a thoracotomy, it requires operator training and skill to add to the beneficial effect of damage control resuscitation and surgery. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Videothoracoscopy in the treatment of early empyema: an initial experience.

PubMed Central

Hornick, P.; Townsend, E. R.; Clark, D.; Fountain, S. W.

1996-01-01

Seventeen consecutive patients were referred for management of empyema between April 1991 and March 1992. Fourteen patients defined as having an 'early' empyema were initially treated by videothoracoscopy. The other three patients, defined as having a 'late' empyema proceeded directly to thoracotomy. Videothoracoscopy was successful in 10 out of the 14 patients. The mean postoperative stay was 7.8 days. At a mean follow-up at 16.7 months, these patients were rendered apyrexial with full lung expansion and no residual pleural collection. The postoperative results were at least equivalent to other conventional forms of treatment without an undue level of complications. In this series, thoracoscopy was found to be successful when symptoms had been present up to 31 days before presentation at the first hospital, and the mean length of treatment before referral to Harefield was 47 days. It is now our policy to videothoracoscope all patients with empyema thoracis, regardless of the length of referral. It may circumvent the need for a thoracotomy, it does not add any increased risk of complications, and does not appreciably increase the length of hospital stay should thoracotomy ultimately be required.

Descriptive study that proposed to compare the qualitative and quantitative behavior of the pain in lateral posterior thoracotomy patients. The sample was consisted of 18 individuals with an average age of 44 years. The instruments used were physiotherapy evaluation form, numerical pain scale and McGill questionnaire for pain. The pain on the numerical pain scale was considered moderate(5) for both sexes. The descriptors of the McGill questionnaire choosen by the patients with higher frequency were: in the sensorial component, beat4, pointed1, shock2, final and pull2; in the afetive component, tired1, bored1, punishald1 and miserable1 and in the evaluative component was flat. The characteristics of pain in the sensorial group were more evidents on male group. No significant statistical difeferences were observed between quantitative answers concerning pain between the men and women. On the qualitative aspects , was observed an predominancy of the same descriptors of pain in afetive component for both sexes. Pain intensity was categorized as moderate. No significant statistical difference were observed between the pain on the post-operatory lateral posterior thoracotomy. These data demonstrate a necessity for an analysis with a larger study group.

[Haemothorax after blunt thoracic trauma].

PubMed

Siller, J; Havlícek, K

2009-05-01

Haemothorax is frequent consequence of blunt and penetrating thoracic trauma and is usually associated with pneumothorax. The occurence of haemothorax in blunt thoracic trauma patients is estimated between 25-75%. The reason of bleeding is impairment of intercostal arteries or lung parenchyma after trauma of the ribs. Uncontrolled bleeding is the main cause of the death. The article is focused on the treatment of this injury. There were enrolled 238 patients with thoracic trauma, who were admitted into our department, into the study. The average age of the patients was 42.5 years. The ISS > or = 16 were in 101 patients. Forty two patients were artefitially ventilated. Conservative treatment prevails, almost in 65%. Special care was indicated in patients with haemothorax (fluidotoraxem). Clinically and based on other screening methods the presence of the fluid in thoracic cavity was in 131 patients. Surgical treatment (punction, drainage, videothoracoscopy and thoracotomy) was necessary in 47 (35.0%). Thoracotomy for the bleeding was indicated in seven cases (5.3 %). In diagnostics and in treatment of the bleeding in thoracic trauma patients the most important factor is clinical status of the patient. Indication for thoracotomy must be unambigous. Massive haemotorax leads to restrictive ventilation disorder with decreased preload and can be activator of the haemocolaguation disorders. This fact decreases chance for the survival of the patient.

[Use of bronchial blocker in emergent thoracotomy in presence of upper airway hemorrhage, and cervical spine fracture: a difficult decision].

PubMed

Almeida, Carlos; Freitas, Maria João; Brandão, Diogo; Assunção, José Pedro

2018-01-13

Female, 85 y.o., weighting 60kg, multiple trauma patient. After an initial laparotomy, an emergent thoracotomy was performed using a bronchial blocker for lung isolation (initial active suction was applied). During surgery, bronchial cuff was deflated, causing a self-limited tracheal blood flooding. A second lung isolation was attempted but it was not as effective as initially. Probably, a lung collapse with the same bronchial blocker was impaired in the second attempt because of the obstruction of bronchial blocker lumen by intraoperative endobronchial hemorrhage. Bronchial blocker active suction may contribute to obtain or accelerate lung collapse, particularly in patients that do not tolerate ventilator disconnection technique or lung surgical compression. The use of bronchial blockers technology was a valuable alternative to double lumen tubes in this case of emergent thoracotomy in the context of a patient having thoracic, abdominal trauma, severe laceration of tongue and apophysis odontoid fracture associated to massive hemorrhage, despite several pitfalls that could compromise its use. The authors intend to discuss the advantages and disadvantages of bronchial blockers comparing to double-lumen tubes for lung isolation, and the risks of our approach, in this complex multitrauma case.

Conventional thoracotomy is currently used as a standard procedure, and is often required to treat numerous diseases. Additionally, rib resections are occasionally required to maintain an adequate field of view for surgery. The benefits of using rib pins for chest closure following such procedures have not yet been established. This study sought to evaluate the usefulness of rib pins in reducing acute postoperative pain. Thirty-three consecutive patients with lung cancer underwent lobectomies using the posterolateral approach. The patients were rib-resected and reconstructed with two techniques: 21 patients with absorbable rib pins (ARP group) and 12 patients by ligation with absorbable sutures (LAS group). Intensity of pain was assessed during the 3 days immediately following surgery. The two groups were assessed using the visual analogue scale (VAS) as a pain scale, amounts consumed of patient-controlled analgesics (PCA), and additional chest x-rays. On the first day following surgery, the mean VAS intensity of the ARP group for patient motion was 2.71 +/- 2.14, compared to 5.33 +/- 2.99 in the LAS group. After three days, the mean score for the ARP group was 1.98 +/- 1.89, compared to 4.60 +/- 1.97 in the LAS group. Scores in the ARP group were significantly lower than in the LAS group one day and three days following thoracotomy. The LAS group (55.0 +/- 15.9 times) made more frequent requests than the ARP group (16.1 +/- 10.3 times). The PCA requirement was also significantly lower in the ARP group. Excessive derangement of the rib (grade 2) was found in one case (4.7 %) in the ARP group compared to five cases (41.6 %) in the LAS group. Rib shifts were seen in numerous cases in the LAS group compared to the ARP group as measured by chest x-rays. Use of absorbable rib pins reduced postoperative pain and may improve long-term prospects for the post-thoracotomy course.

Nosocomial and ventilator-associated pneumonia (VAP) are causes of significant morbidity and mortality in hospitalized patients. We analyzed a) the incidence and the outcome of pneumonias caused by different pathogens in the intensive care unit (ICU) of a medium-sized twenty-four bed community hospital and b) the incidence of complications of such pneumonias requiring surgical intervention such as thoracotomy and decortication. We retrospectively reviewed the charts of patients diagnosed with nosocomial and ventilator-associated pneumonia in our ICU. Their bronchoalveolar lavage (BAL) and sputum cultures, antibiograms, and other clinical characteristics, including complications and need for tracheostomy, thoracotomy and decortication were studied. In a span of one year (2011-12), 43 patients were diagnosed with nosocomial pneumonia in our ICU. The median simplified acute physiology score (SAPS II) was 39. One or more gram negative organisms as the causative agents were present in 85% of microbiologic samples. The three most prevalent gram negatives were Stenotrophomonas maltophilia (34%), Pseudomonas aeurginosa (40%), and Acinetobacter baumannii (32%). Twenty eight percent of bronchoalveolar samples contained Staphylococcus aureus. Eight three percent of patients required mechanical ventilation postoperatively and 37% underwent tracheostony. Thirty five percent underwent thoracotomy and decortication because of further complications such as empyema and non-resolving parapneumonic effusions. A. baumannii, Klebsiella pneumonia extended spectrum beta lactam (ESBL) and P. aeurginosa had the highest prevalence of multi drug resistance (MDR). Fifteen patients required surgical intervention. Mortality from pneumonia was 37% and from surgery was 2%. Nosocomial pneumonias, in particular the ones that were caused by gram negative drug resistant organisms and their ensuing complications which required thoracotomy and decortication, were the cause of significant morbidity in our intensive care unit. Preventative and more intensive and novel infection control interventions in reducing the incidence of nosocomial pneumonias are strongly emphasized.

The objectives of this study were to investigate whether continuous intravenous ketamine during the first 72 hours after thoracotomy could reduce the incidence and intensity of chronic postthoracotomy pain (CPTP) and to define the incidence and risk factors of CPTP. Seventy-eight patients receiving thoracotomy for lung tumor (benign or malignant) were randomly divided into two groups: ketamine group (n = 31) and control groups (n = 47). Patients in the ketamine group received intravenous ketamine 1 mg/kg before incision, followed by 2 μg/kg/minute infusion for 72 hours plus sufentanil patient-controlled intravenous analgesia after thoracotomy. Patients in the control group received intravenous a 0.9% normal saline and infusion plus sufentanil patient-controlled intravenous analgesia. The solutions patients received were blinded. The numerical rating scale (NRS) pain scores and the incidence and risk factors of CPTP were recorded during the first 6 months after surgery. Compared with control group, the incidence of chronic pain in the ketamine group did not decrease at 2 months (χ(2) = 1.599, P = .206) and 6 months (χ(2) = 0.368, P = .544) after surgery. Postoperative pain scores in the ketamine group were not significantly different from those of the control group patients at 2 months (U = 677.5, P = .593) and 6 months (U = 690.5, P = .680). The incidence of CPTP was 78.2% (61/78) at 2 months and 53.8% (42/78) at 6 months after surgery. Retractor used time (OR = 5.811, P = .002), inadequate acute pain control (NRS ≥ 5) (OR = 5.425, P = .048), and chemotherapy (OR = 3.784, P = .056) were independent risk factors for chronic postthoracotomy pain. The authors conclude that continuous intravenous ketamine (2 μg/kg/min) during the first 72 hours after thoracotomy was not beneficial to prevent chronic postthoracotomy pain. The independent risk factors for chronic postthoracotomy pain were retractor used time, inadequate acute pain control, and chemotherapy.

In the last decade, video-assisted thoracoscopic surgery (VATS) lobectomy for non-small cell lung cancer (NSCLC) has had a major effect on thoracic surgery. Retrospective series have reported benefits of VATS when compared with open thoracotomy in terms of postoperative pain, postoperative complications and length of hospital stay. However, no large randomised control trial has been conducted to assess the reality of the potential benefits of VATS lobectomy or its medicoeconomic impact. The French National Institute of Health funded Lungsco01 to determine whether VATS for lobectomy is superior to open thoracotomy for the treatment of NSCLC in terms of economic cost to society. This trial will also include an analysis of postoperative outcomes, the length of hospital stay, the quality of life, long-term survival and locoregional recurrence. The study design is a two-arm parallel randomised controlled trial comparing VATS lobectomy with lobectomy using thoracotomy for the treatment of NSCLC. Patients will be eligible if they have proven or suspected lung cancer which could be treated by lobectomy. Patients will be randomised via an independent service. All patients will be monitored according to standard thoracic surgical practices. All patients will be evaluated at day 1, day 30, month 3, month 6, month 12 and then every year for 2 years thereafter. The recruitment target is 600 patients. The protocol has been approved by the French National Research Ethics Committee (CPP Est I: 09/06/2015) and the French Medicines Agency (09/06/2015). Results will be presented at national and international meetings and conferences and published in peer-reviewed journals.

Advances in mechanical circulatory support have been critical in bridging patients awaiting heart transplantation. In addition, improvement in device durability has enabled left ventricular assist device therapy to be applied as destination therapy in those not felt to be transplant candidate. Because of the increasing complexity of patients, there continues to be a need for alternative strategies for device implantation to bridge high-risk patients awaiting heart transplantation, wherein the risks of numerous previous sternotomies may be prohibitive. We present a unique technique for placement of the HeartWare ventricular assist device via left anterior thoracotomy to the descending aorta in a patient awaiting heart transplantation with a history of multiple previous sternotomies.

A 57-year-old diabetic and hypertensive man presented with a short history of fever, dry cough and right side chest pain. A chest radiograph showed right pleural based homogenous shadow in middle and lower zones with obliteration of right costo-phrenic angle suggestive of right side effusion. Aspiration of pleural fluid revealed frank pus for which inter-costal tube drainage was performed. Due to persistence of empyema, the patient was subjected to thoracoscopy. Thoracoscopy showed multiloculated empyema. Thoracoscopic pleural biopsy and fluid showed septate fungal hyphae. Thoracotomy and parietal pleurectomy, with resection of part of right lower lobe, was carried out. Pleural fluid, pleural and lung tissue culture grew Aspergillus fumigatus. The patient showed good recovery with voriconazole after thoracotomy. PMID:20539768

Transcutaneous Electrical Nerve Stimulation Reduces Post-Thoractomy Ipsilateral Shoulder Pain. A Prospective Randomized Study.

PubMed

Esteban González, Pedro; Novoa, Nuria M; Varela, Gonzalo

2015-12-01

The patient's position during an axillary thoracotomy can cause postoperative pain and decrease mobility of the ipsilateral shoulder. In this study, we assessed whether the implementation of a standardized analgesia program using transcutaneous electrical nerve stimulation (TENS) decreases local pain and improves ipsilateral shoulder mobility. Randomized, single-blind, single-center clinical trial of 50 patients who had undergone anatomical lung resection via axillary muscle-sparing thoracotomy. Patients were treated with TENS devices for 30 minutes every 8 hours, beginning on postoperative day 1. Pain and mobility of the affected limb were recorded at the same time on postoperative days 1 through 3. A visual analogue scale was used for pain assessment and shoulder mobility was assessed with a goniometer. Results were compared using a non-parametric test. Twenty-five patients were randomized to each group. Mean age of the control group was 62.7±9.3 years and 63.4±10.2 years in the experimental group. Shoulder mobility parameters were similar in both groups on all postoperative days. However, pain during flexion significantly decreased on day 2 (P=.03) and day 3 (P=.04) in the experimental group. The use of TENS decreases pain from shoulder flexion in patients undergoing axillary thoracotomy for pulmonary resection. Copyright © 2014 SEPAR. Published by Elsevier Espana. All rights reserved.

Minimally invasive mitral valve surgery through right mini-thoracotomy: recommendations for good exposure, stable cardiopulmonary bypass, and secure myocardial protection.

PubMed

Ito, Toshiaki

2015-07-01

An apparent advantage of minimally invasive mitral surgery through right mini-thoracotomy is cosmetic appearance. Possible advantages of this procedure are a shorter ventilation time, shorter hospital stay, and less blood transfusion. With regard to hard endpoints, such as operative mortality, freedom from reoperation, or cardiac death, this method is reportedly equivalent, but not superior, to the standard median sternotomy technique. However, perfusion-related complications (e.g., stroke, vascular damage, and limb ischemia) tend to occur more frequently in minimally invasive technique than with the standard technique. In addition, valve repair through a small thoracotomy is technically demanding. Therefore, screening out patients who are not appropriate for performing minimally invasive surgery is the first step. Vascular disease and inadequate anatomy can be evaluated with contrast-enhanced computed tomography. Peripheral cannulation should be carefully performed, using transesophageal echocardiography guidance. Preoperative detailed planning of the valve repair process is desirable because every step is time-consuming in minimally invasive surgery. Three-dimensional echocardiography is a powerful tool for this purpose. For satisfactory exposure and detailed observation of the valve, a special left atrial retractor and high-definition endoscope are useful. Valve repair can be performed in minimally invasive surgery as long as cardiopulmonary bypass is stable and bloodless exposure of the valve is obtained.

Pulmonary bullae and pneumothorax have various etiologies in veterinary medicine. We diagnosed multiple pulmonary bullae combined with or without pneumothorax by computed tomography (CT) or necropsy in seven rhesus macaques (Macaca mulatta) imported from China. Two of seven rhesus macaques accompanied by pneumothorax were cured by fixation of ruptured lung through left or right 3rd intercostal thoracotomy. Pneumonyssus simicola, one of the etiologies of pulmonary bullae, was not detected from tracheobronchiolar lavage. To the best of our knowledge, this is the first case report on the CT-aided diagnosis of pulmonary bullae and the successful treatment of combined pneumothorax by thoracotomy in non-human primates (NHPs). © 2017 John Wiley & Sons A/S.

Azygos vein aneurysm is very rare and is usually found incidentally because of its clinical silence. We report a case of recurrent pleural effusion caused by an azygos vein aneurysm in a patient with moderate mitral valve regurgitation (MR) and tricuspid valve regurgitation (TR). Since valve disease is considered a significant precipitating factor for both dyspnoea and pleural effusion, we decided to study the aetiologies of these conditions concomitantly. Azygos vein aneurysm resection in combination with tricuspid and mitral valve repair using cardiopulmonary bypass was performed successfully through a right anterior thoracotomy. The postoperative course was uneventful, and the patient reported improved exercise capacity. © The Author 2016.

The natural history and optimal management of retained hemothorax (RH) after chest tube placement is unknown. The intent of our study was to determine practice patterns used and identify independent predictors of the need for thoracotomy. An American Association for the Surgery of Trauma multicenter prospective observational trial was conducted, enrolling patients with placement of chest tube within 24 hours of trauma admission and RH on subsequent computed tomography of the chest. Demographics, interventions, and outcomes were analyzed. Logistic regression analysis was used to identify the independent predictors of successful intervention for each of the management choices chosen and complications. RH was identified in 328 patients from 20 centers. Video-assisted thoracoscopy (VATS) was the most commonly used initial procedure in 33.5%, but 26.5% required two and 5.4% required three procedures to clear RH or subsequent empyema. Thoracotomy was ultimately required in 20.4%. The strongest independent predictor of successful observation was estimated volume of RH ≤300 cc (odds ratio [OR], 3.7 [2.0-7.0]; p < 0.001). Independent predictors of successful VATS as definitive treatment were absence of an associated diaphragm injury (OR, 4.7 [1.6-13.7]; p = 0.005), use of periprocedural antibiotics for thoracostomy placement (OR, 3.3 [1.2-9.0]; p = 0.023), and volume of RH ≤900 cc (OR, 3.9 [1.4-13.2]; p = 0.03). No relationship between timing of VATS and success rate was identified. Independent predictors of the need for thoracotomy included diaphragm injury (OR, 4.9 [2.4-9.9]; p < 0.001), RH >900 cc (OR, 3.2 [1.4-7.5]; p = 0.007), and failure to give periprocedural antibiotics for initial chest tube placement (OR 2.3 [1.2-4.6]; p = 0.015). The overall empyema and pneumonia rates for RH patients were 26.8% and 19.5%, respectively. RH in trauma is associated with high rates of empyema and pneumonia. VATS can be performed with high success rates, although optimal timing is unknown. Approximately, 25% of patients require at least two procedures to effectively clear RH or subsequent pleural space infections and 20.4% require thoracotomy.

Emergency department thoracotomy (EDT) must be rapid and well-executed. Currently there are no defined benchmarks for EDT procedural milestones. We hypothesized that trauma video review (TVR) can be used to define the 'normative EDT' and generate procedural benchmarks. As a secondary aim, we hypothesized that data collected by TVR would have less missingness and bias than data collected by review of the Electronic Medical Record (EMR). We used continuously recording video to review all EDTs performed at our centre during the study period. Using skin incision as start time, we defined four procedural milestones for EDT: 1. Decompression of the right chest (tube thoracostomy, finger thoracostomy, or clamshell thoracotomy with transverse sternotomy performed in conjunction with left anterolateral thoracotomy) 2. Retractor deployment 3. Pericardiotomy 4. Aortic Cross-clamp. EDTs with any milestone time ≥ 75 th percentile of time or during which a milestone was omitted were identified as outliers. We compared rates of missingness in data collected by TVR and EMR using McNemar's test. 44 EDTs were included from the study period. Patients had a median age of 30 [IQR 25-44] and were predominantly African-American (95%) males (93%) with penetrating trauma (95%). From skin incision, median times in minutes to milestones were as follows: right chest decompression: 2.11 [IQR 0.68-2.83], retractor deployment 1.35 [IQR 0.96-1.85], pericardiotomy 2.35 [IQR 1.85-3.75], aortic cross-clamp 3.71 [IQR 2.83-5.77]. In total, 28/44 (64%) of EDTs were either high outliers for one or more benchmarks or had milestones that were omitted. For all milestones, rates of missingness for TVR data were lower than EMR data (p < 0.001). Video review can be used to define normative times for the procedural milestones of EDT. Steps exceeding the 75 th percentile of time were common, with over half of EDTs having at least one milestone as an outlier. Data quality is higher using TVR compared to EMR collection. Future work should seek to determine if minimizing procedural technical outliers improves patient outcomes. Copyright © 2018 Elsevier Ltd. All rights reserved.

Double jeopardy revisited: clinical decision making in unstable patients with, thoraco-abdominal stab wounds and, potential injuries in multiple body cavities.

In the setting of the hypovolaemic patient with a thoraco-abdominal stab wound and potential injuries in both the chest and abdomen, deciding which cavity to explore first may be difficult.Opening the incorrect body cavity can delay control of tamponade or haemorrhage and exacerbate hypothermia and fluid shifts. This situation has been described as one of double jeopardy. All stab victims from July 2007 to July 2009 requiring a thoracotomy and laparotomy at the same operation were identified from a database. Demographics, site and nature of injuries, admission observations and investigations as well as operative sequence were recorded. Correct sequencing was defined as first opening the cavity with most lethal injury. Incorrect sequencing was defined as opening a cavity and finding either no injury or an injury of less severity than a simultaneous injury in the unopened cavity. The primary outcome was survival or death. Sixteen stab victims underwent thoracotomy and laparotomy during the same operation. All were male with an age range of 18–40 (mean/median 27). Median systolic blood pressure on presentation was 90 mm Hg. (quartile range 80–90 mm Hg). Median base excess was 6.5 (quartile range 12 to 2.2). All the deaths were the result of cardiac injuries. Incorrect sequencing occurred in four patients (25%). In this group there were four negative abdominal explorations prior to thoracotomy with two deaths. There was one death in the correct sequencing group. Incorrect sequencing in stab victims who require both thoracotomy and laparotomy at the same sitting is associated with a high mortality. This is especially true when the abdomen is incorrectly entered first whilst the life threatening pathology is in the chest. Clinical signs may be confusing, leading to incorrect sequencing of exploration. The common causes for confusion include failure to appreciate that cardiac tamponade does not present with bleeding and difficulty in assessing peritonism in an unstable patient with multiple stab wounds. In the setting of the unstable patient with stab wounds and suspected dual cavity injuries the chest should be opened first followed by the abdomen. 2010 Elsevier Ltd. All rights reserved.

Randomised controlled pilot study to investigate the effectiveness of thoracic epidural and paravertebral blockade in reducing chronic post-thoracotomy pain: TOPIC feasibility study protocol.

Open chest surgery (thoracotomy) is considered the most painful of surgical procedures. Forceful wound retraction, costochondral dislocation, posterior costovertebral ligament disruption, intercostal nerve trauma and wound movement during respiration combine to produce an acute, severe postoperative pain insult and persistent chronic pain many months after surgery is common. Three recent systematic reviews conclude that unilateral continuous paravertebral blockade (PVB) provides analgesia at least equivalent to thoracic epidural blockade (TEB) in the postoperative period, has a lower failure rate, and symptom relief that lasted months. Crucially, PVB may reduce the development of subsequent chronic pain by intercostal nerve protection or decreased nociceptive input. The overall aim is to determine in patients who undergo thoracotomy whether perioperative PVB results in reducing chronic post-thoracotomy pain (CPTP) compared with TEB. This pilot study will evaluate feasibility of a substantive trial. TOPIC is a randomised controlled trial comparing the effectiveness of TEB and PVB in reducing CPTP. This is a pilot study to evaluate feasibility of a substantive trial and study processes in 2 adult thoracic centres, Heart of England NHS Foundation Trust (HEFT) and University Hospital of South Manchester NHS Foundation Trust (UHSM). The primary objective is to establish the number of patients randomised as a proportion of those eligible. Secondary objectives include evaluation of study processes. Analyses of feasibility and patient-reported outcomes will primarily take the form of simple descriptive statistics and where appropriate, point estimates of effects sizes and associated 95% CIs. The study has obtained ethical approval from NHS Research Ethics Committee (REC number 14/EM/1280). Dissemination plan includes: informing patients and health professionals; engaging multidisciplinary professionals to support a proposal of a definitive trial and submission for a full HTA application dependent on the success of the study.

Transcatheter aortic valve implantation (TAVI) and minimally invasive aortic valve replacement (mini-thoracotomy, mini-sternotomy, MIAVR) have become an appealing alternative to conventional surgical (SAVR) treatment of severe aortic stenosis (AS) in high-risk patients. Aim of the study was to evaluate the quality of life (QoL) in patients with AS and treated with transfemoral TAVI, SAVR, mini-thoracotomy and mini-sternotomy. One hundred and seventy-three patients with symptomatic AS were enrolled in 2011-2013. TAVI group consisted of 39 patients (22.5%), mini-sternotomy was performed in 44 patients (25.5%), mini-thoracotomy in 50 (29%), and AVR in 40 patients (23%). QoL was assessed perioperatively, 12 and 24 months after aortic valve replacement (AVR) by Minnesota Living with Heart Failure Questionnaire (MLHFQ) and EQ-5D-3L. Median follow-up was 583.5 (IQR: 298-736) days. Improvement of health status after procedure in comparison with pre-operative period was significantly more often reported after TAVI in perioperative period (90.3%; P = 0.004) and 12 months after procedure (100%, P = 0.02). Global MLHFQ, physical and emotional dimension score at 30-day from AVR presented significant improvement after TAVI in comparison with surgical methods (respectively: 8.3(±8.6), P = 0.003; 4.1(±5.9), P = 0.01; 1.5(±2.6), P = 0.005). Total MLHFQ score was significantly lower (better outcome) in TAVI patients 1 year after procedure (4.8(±6.8), P = 0.004), no differences in somatic and emotional component were found. No differences were found in MLHFQ score 24 months after AVR. Data from EQ-D5-3L questionnaire demonstrated significant improvement of QoL at 30-day follow-up after TAVI in comparison with surgical methods (1.2(±1.7), P = 0.0008). TAVI improves QoL in perioperative and 12 months observation in comparison with mini-thoracotomy, mini-sternotomy and SAVR. Improvement in QoL was obtained in both generic and disease specific questionnaires. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Chambers, Elise; Yager, Joel; Apfeldorf, William; Camps-Romero, Eduardo

2007-01-01

A 20-year-old man presented to an emergency department with dramatic, sudden-onset, tearing chest pain. He also claimed to have been previously diagnosed with Ehler-Danlos syndrome and a previous Type I aortic dissection (intimal tear of ascending aorta), rapidly increasing his treating physician's suspicion of an emergent aortic dissection. The patient was quickly transferred to a large university hospital, where he underwent a median sternotomy and thoracotomy, with no aortic pathology found on operation and biopsy. After the patient's postoperative recovery, he was treated at a mental health facility, where he remained ambivalent about his psychiatric condition and did not respond well to treatment. This case report describes a unique case of factitious disorder that led to a serious operative intervention and subsequent psychiatric care and assesses factors that might have contributed to his hospital course.

Hémothorax spontané révélant une vascularite de Wegener chez une femme enceinte

L’hémothorax spontané demeure une pathologie rare. Ses étiologies sont multiples mais restent parfois inconnues. Chez certains patients, la thoracotomie peut être le seul recours pour déterminer son origine. Les vascularites n’ont pas été rapporté comme cause habituelle des hémothorax spontanés. La grossesse ne semble pas avoir d’effet causal, ni aggravant des hémothorax spontanés, ni des vascularites. Nous rapportons une observation assez particulière d’une jeune patiente, présentant au cours de sa grossesse un hémothorax spontané secondaire à une vasularite de type Wegener, diagnostiquée par la biopsie pleurale faite au cours d’une thoracotomie exploratrice et confirmée par le dosage des ANCA.

To identify the characteristic features of pneumothorax patients treated surgically. The retrospective study was conducted at Gazi Yasargil Education and Research Hospital Thoracic Surgery Clinic, Diyarbakir, Turkey and comprised records of pneumothorax patients from January 2004 to December 2014. They were divided into two groups as spontaneous and traumatic. Patients who had not undergone any surgical intervention were excluded. Mean age, gender distribution, location of the disease, type of pneumothorax, and treatment method were noted. Among patients with spontaneous pneumothorax, age and months distribution, smoking habits, pneumothorax size, and treatment method were assessed. The effect of gender, location, comorbid disease, smoking, subgroup of disease, and pneumothorax size on surgical procedures were also investigated. The mean age of the 672 patients in the study was 34.5±6.17 years. There were 611(91%) men and 61(9%) women. Disease was on the right side in 360(53.6%) patients, on the left side in 308(45.8%), and bilateral in 4(0.59%). Besides, 523(77.8%) patients had spontaneous, and 149(22.7%) had traumatic pneumothorax. Overall, 561(83.5%) patients had been treated with tube thoracostomy, whereas 111(16.5%) were treated with thoracotomy/thoracoscopic surgery. The presence of comorbid diseases, being primary, and being total or subtotal according to partial were found to create predisposition to thoracotomy/ thoracoscopic surgery (p<0.05 each). In the case of pneumothorax being total, the presence of comorbid diseases, and the increase in pneumothorax size, thoracotomy or thoracoscopic surgery is preferred.

Background The goal of this study was to detect the predictors of chronic pain at 6 months after thoracic surgery from a comprehensive evaluation of demographic, psychosocial, and surgical factors. Methods Thoracic surgery patients were enrolled 1 week before surgery and followed-up 6 months post-surgery in this prospective, observational study. Comprehensive psychosocial measurements were assessed before surgery. The presence and severity of pain was assessed at 3 and 6 months after surgery. One-hundred seven patients were assessed during the first 3 days after surgery and 99 (30 thoracotomy and 69 video-assisted thoracoscopic surgery, thoracoscopy) patients completed the 6 months follow-up. Patients with vs without chronic pain related to thoracic surgery at 6 months were compared. Results Both incidence (p = 0.37) and severity (p = 0.97) of surgery-related chronic pain at 6 months were similar after thoracotomy (33%, 95% confidence interval [CI]: 17% to 53%, 3.3 ± 2.1) and thoracoscopy (25%, 95% CI: 15% to 36%, 3.3 ± 1.7). Both frequentist and Bayesian multivariate models revealed that severity of acute pain (numerical rating scale, 0–10) is the measure associated with chronic pain related to thoracic surgery. Psychosocial factors and quantitative sensory testing were not predictive. Conclusions There was no difference in the incidence and severity of chronic pain at 6 months in patients undergoing thoracotomy versus thoracoscopy. Unlike other post-surgical pain conditions, none of the pre-operative psychosocial measurements were associated with chronic pain after thoracic surgery. PMID:28248713

Penetrating chest injuries are the most frequent causes of serious demage and death in wounded indivisuals. In reports from the last wars where wounds caused by high velocity projectiles predominated, thoracotomies were perfomed in about 15% of the wounded individuals, mostly encompassing injuries of the heart and great vessels, accomanied by massive bleeding that could not be resolved by chest tube insertion. This retrospective analysis was performed on the medical records of 477 patients tretaed for isolated penetrating chest injuries in Department of Thoracic Surgery Clinical Center of the University in Sarajevo between april 1992 - june 1995. We analised the ways of their menagement with special view on pleural drainage, indication for this method and results of treatment. 398 (83,4%) wounded individuals have been treated with pleural tube inserting as definitive mesaure and for the urgent thoracotomy there were 79 (16,6%) patients left. Average hospital treatment in wounded drained patients was 7,68 days. With shrapnels there were 357 (74,84%) wounded individuals, and with bullet 120 (25,16%) wounded individuals. The complications of plaural tube inserting were - empyema in 34 (7,13%) patients and there were no other complications. Chest tube inserting as definitive mesaure was used in 398 (83,44%) patients. Chest tube inserting as preoperative measure (urgent thoracotomy) was used in 79 (16,56%) patients. There were 460 (96,44%) healed patients. Death occurred in 17 (3,56%) patients.

Introduction The indications for videothoracoscopy are very broad and include the treatment of mediastinal tumours. Aim To present our experience of using the minimally invasive technique in treating benign neurogenic tumours. Material and methods Twenty-two patients were treated due to tumours of the posterior mediastinum from 2003 to 2012. The size of the tumours ranged from 2 cm to 25 cm. Tumours up to the size of 6 cm were treated using videothoracoscopy (VT), bigger ones through thoracotomy. Results The videothoracoscopy technique was used in 17 patients, thoracotomy in 5. In 2 cases conversion was required due to adhesions in the pleural cavity preventing VT treatment. Complications related to the procedure were not observed. The average time of hospital stay after VT treatment was 4 days, while after thoracotomy it was 6 days. Histologically, tumours of benign nature were found in all cases. Schwannoma was diagnosed in 15 patients, ganglioneuroma in 3 patients, neurofibroma in 3 patients, and chemodectoma in 1 patient. None of the 3 cases of neurofibroma was associated with Recklinghausen's disease. At a mean follow-up of 60 months no recurrence of the tumour was found. Conclusions In the case of tumours up to 6 cm the best surgical technique is videothoracoscopy. In the case of large tumours the best access is the open technique. The minimally invasive technique allows one to shorten the patient's treatment time, reduce postoperative pain and obtain a good cosmetic effect of the treatment. PMID:25337152

2017-12-01

Our objective is to show the effect that standardization of surgical trays has on the number of instruments sterilized and on cost. We reviewed our most commonly used surgical trays with the 3 general thoracic surgeons in our division and agreed upon the least number of surgical instruments needed for mediastinoscopy, video-assisted thoracoscopic surgery, robotic thoracic surgery, and thoracotomy. We removed 59 of 79 instruments (75%) from the mediastinoscopy tray, 45 of 73 (62%) from the video-assisted thoracoscopic surgery tray, 51 of 84 (61%) from the robotic tray, and 50 of 113 (44%) from the thoracotomy tray. From January 2016 to December 2016, the estimated savings by procedure were video-assisted thoracoscopic surgery (n = 398) $21,890, robotic tray (n = 231) $19,400, thoracotomy (n = 163) $15,648, and mediastinoscopy (n = 162) $12,474. Estimated total savings were $69,412. The weight of the trays was reduced 70%, and the nonsteamed sterilization rate (opened trays that needed to be reprocessed) decreased from 2% to 0%. None of the surgeons requested any of the removed instruments. Standardization of thoracic surgical trays is possible despite having multiple thoracic surgeons. This process of lean (the removal of nonvalue steps or equipment) reduces the number of instruments cleaned and carried and reduces cost. It may also reduce the incidence of "wet loads" that require the resterilization of instruments. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Myocardial damage is an independent predictor of adverse outcome following cardiac surgery and myocardial protection is one of the key factors to achieve successful outcomes. Cardioplegia with Custodiol is currently the most used cardioplegia during minimally invasive cardiac surgery (MICS). Different randomized controlled trials compared blood and Custodiol cardioplegia in the context of traditional cardiac surgery. No data are available for MICS. The aim of this study was to compare the efficacy of cold blood versus Custodiol cardioplegia during MICS. We retrospectively evaluated 90 patients undergoing MICS through a right mini-thoracotomy in a three-year period. Myocardial protection was performed using cold blood (44 patients, CBC group) or Custodiol (46 patients, Custodiol group) cardioplegia, based on surgeon preference and complexity of surgery. The primary outcomes were post-operative cardiac troponin I (cTnI) and creatine kinase MB (CKMB) serum release and the incidence of Low Cardiac Output Syndrome (LCOS). Aortic cross-clamp and cardiopulmonary bypass times were higher in the Custodiol group. No difference was observed in myocardial injury enzyme release (peak cTnI value was 18±46 ng/ml in CBC and 21±37 ng/ml in Custodiol; p=0.245). No differences were observed for mortality, LCOS, atrial or ventricular arrhythmias onset, transfusions, mechanical ventilation time duration, intensive care unit and total hospital stay. Custodiol and cold blood cardioplegic solutions seem to assure similar myocardial protection in patients undergoing cardiac surgery through a right mini-thoracotomy approach.

Thoracoscopy: medical versus surgical—in the management of pleural diseases

PubMed Central

2015-01-01

Diseases of the pleura continue to affect a large population of patients worldwide and in the United States. Pleural fluid analysis and accompanying imaging of the pleura including chest X-rays, chest computed tomography (CT) scan and chest ultrasonography are among the first steps in the management of pleural effusions. When further diagnostic or therapeutic work up is necessary, open thoracotomy and thoracoscopy come to mind. However, given the significant morbidity and mortality associated with open thoracotomy, and the advances in medicine and medical instruments, thoracoscopy has now become a routine procedure in the management of the disease of the chest including pleura. Debates about surgical vs. medical thoracoscopy (MT) are ongoing. In the following pages we review the literature and discuss the similarities and differences between the two procedures, as well as their indications, contraindications, complications and efficacy in the management of pleural diseases.

BACKGROUND: Problems in the management of thoracic trauma have stimulated the search for an alternative to underwater seals for drainage of the pleural cavity. A chest drainage bag incorporating a one way flutter valve has been compared with underwater seal drains in a randomised clinical trial. METHODS: During June-December 1989 119 patients undergoing elective thoracotomy were randomised to receive postoperative chest drainage by drainage bags (56 patients, 87 drains) or by underwater seal drains (63 patients, 98 drains). Daily drainage volumes, the requirement for pleural suction, mobility, and complications were recorded prospectively. RESULTS: There was no significant difference between the two groups in the mean volume drained, the requirements for pleural suction, or the occurrence of complications. Patients with drainage bags were fully mobile 23 hours (95% confidence interval 0-47 hours) earlier than the others. CONCLUSIONS: When used after elective thoracotomy drainage bags are safe and effective and permit earlier mobility than underwater seal drains. PMID:1496507

To describe a case of a focal right ventricular rupture following removal of a rib-associated telangiectatic osteosarcoma (TOS) in a dog. A 2-year-old spayed female mixed-breed dog, weighing 20 kg, was presented in compensated hypovolemic shock due to active bleeding into the thoracic cavity. The dog was stabilized with appropriate fluid administration. Subsequent computed tomographic examination revealed a large mineralized mass originating from the body of a rib and displacing the heart. Two days after surgical removal of this mass, focal right ventricular rupture occurred and the dog died. The mass was later identified as a TOS. Although hemothorax secondary to TOS has been described previously, this report describes for the first time, spontaneous focal right ventricular rupture as a rare complication of thoracotomy and rib resection for the removal of a rib-associated, intrathoracic TOS.

Background After thoracic surgery, adhesions between the pleura can cause substantial complications. This study investigated the effectiveness of a novel membrane utilizing surface water induction technology to prevent adhesions. Methods Eight beagles were divided into an experimental group (five males) and a control group (three females). The experimental group underwent thoracotomy on both the left and right sides of the chest. Both sides received the membrane, and the membrane on one side was glued to the pleura using tissue adhesive. The control group underwent thoracotomy only on the left side. Two weeks postoperatively, all dogs were sacrificed and adhesions were evaluated macroscopically and microscopically. Results Severe adhesion was seen between the parietal and visceral pleura in all control dogs, whereas the experimental group showed minor adhesion in only one dog on one side. Conclusions Our novel anti-adhesive membrane appeared highly effective in preventing postthoracotomy pleural adhesions. PMID:28654705

An L-shaped incision combining an upper half mid-sternotomy and a left antero-lateral thoracotomy at the fourth intercostal space has been proposed by several authors for extensive aneurysms involving the aortic arch and the proximal thoracic descending aorta. This approach usually requires the division of the left internal thoracic artery at its mid position, thus making it unusable for coronary artery bypass. We herein report a modified surgical approach for simultaneous extensive arch and proximal thoracic descending aorta replacement and coronary artery bypass using the left internal thoracic artery combining a left antero-lateral thoracotomy at the sixth intercostal space and upper mid-sternotomy. The visualization of the whole diseased aorta down to the level below the hilum of the left lung was good, and the integrity of the left internal thoracic artery graft was preserved by early heparin administration before sternotomy.

The catamenial pneumothorax (CP) is defined as recurrent pneumothorax occurring from the day before menstruations until 72 hours after their beginning, but remains a diagnostic and therapeutic problem. We herein report the cases of two young women who presented several episodes of pneumothorax. The first patient (28 years old) underwent 18 recurrent pneumothorax before the diagnosis of CP. The video-assisted mini-thoracotomy found many diaphragmatic perforations, which were sutured after resection and biopsy. The latter patient underwent four pneumothorax before diagnosis of CP. A video-assisted mini-thoracotomy associated with pleurectomy and pleural freshening was then performed. CP is a rare entity of spontaneous pneumothorax often associated with thoracic endometriosis. The difficulty remains in diagnosis (diagnostic delay before the start of appropriate care), as well as in the treatment. Overall, CP requires a multidisciplinary approach combining pulmonology, thoracic surgery and gynecology. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Background: Minimally invasive surgery (MIS) for trauma in pediatric cases remains controversial. Recent studies have shown the validity of using minimally invasive techniques to decrease the rate of negative and nontherapeutic laparotomy and thoracotomy. The purpose of this study was to evaluate the diagnostic accuracy and therapeutic options of MIS in pediatric trauma at a level I pediatric trauma center. Methods: We reviewed cases of patients aged 15 years and younger who had undergone laparoscopy or thoracoscopy for trauma in our institution over the past 20 years. Each case was evaluated for mechanism of injury, computed tomographic (CT) scan findings, operative management, and patient outcomes. Results: There were 23 patients in the study (16 boys and 7 girls). Twenty-one had undergone diagnostic laparoscopy and 2 had had diagnostic thoracoscopy. In 16, there were positive findings in diagnostic laparoscopy. Laparoscopic therapeutic interventions were performed in 6 patients; the remaining 10 required conversion to laparotomy. Both patients who underwent diagnostic thoracoscopy had positive findings. One had a thoracoscopic repair, and the other underwent conversion to thoracotomy. There were 5 negative diagnostic laparoscopies. There was no mortality among the 23 patients. Conclusions: The use of laparoscopy and thoracoscopy in pediatric trauma helps to reduce unnecessary laparotomy and thoracotomy. Some injuries can be repaired by a minimally invasive approach. When conversion is necessary, the use of these techniques can guide the placement and size of surgical incisions. The goal is to shift the paradigm in favor of using MIS in the treatment of pediatric trauma as the first-choice modality in stable patients. PMID:26877626

Some treatment modalities may cause losses in patients' life comfort because of the treatment process. Our aim is to determine the effects of thoracic surgery operations on patients' quality of life. This is a multicenter and prospective study. A hundred patients, who had undergone posterolateral thoracotomy (PLT) and/or lateral thoracotomy (LT), were included in the study. A quality of life questionnaire (SF-36) was used to determine the changes in life comfort. SF-36 was performed before the operation, on the first month, third month, sixth month and twelfth month after the operation. Seventy-two percent (n = 72) of the patients were male. PLT was performed in 66% (n = 66) of the patients, and LT was performed in 34% (n = 34) of the patients. The types of resections in patients were pneumonectomy in four patients, lobectomy in 59 patients and wedge resection in 11 patients. No resection was performed in 26 patients. Thoracotomy caused deteriorations in physical function (PF), physical role (RP), bodily pain (BP), health, vitality and social function scores. The deteriorations observed in the third month improved in the sixth and twelfth months. The PF, RP, BP and MH scores of the patients with lung resection were much more worsened compared with the patients who did not undergo lung resection. Thoracic surgery operations caused substantial dissatisfaction in life comfort especially in the third month postoperatively. The worsening in physical function, physical role, pain and mental health is much more in patients with resection compared with the patients who did not undergo resection. © 2014 John Wiley & Sons Ltd.

Lobectomy for non-small cell lung cancer (NSCLC) can be performed either through open thoracotomy or video-assisted thoracoscopic surgery (VATS). To improve the understanding of current attitudes of the thoracic community toward VATS lobectomy, the Collaborative Research Group conducted the Cross-sectional Survey on Lobectomy Approach (X-SOLA) study. We surveyed a large cohort of lobectomy-performing thoracic surgeons to examine their adoption of VATS lobectomy and their opinions of this technique vs conventional open thoracotomy. Participants included thoracic surgeons identified through an international index search from the Web of Science and the cardiothoracic surgery network. A confidential questionnaire was e-mailed in June 2012. Nonresponders were given two reminder e-mails at monthly intervals. The questionnaire, completed by 838 thoracic surgeons within a 3-month period, identified 416 surgeons who only performed lobectomy through open thoracotomy and 422 surgeons who performed VATS or robotic VATS. Of those who performed VATS, 95% agreed with the definition of "true" VATS lobectomy according to the Cancer and Leukemia Group B trial. Ninety-two percent of surgeons who did not perform VATS lobectomy responded that they were willing to learn this technique, but were hindered by limited resources, exposure, and mentoring. Both groups agreed there was a need for VATS lobectomy training in thoracic residency programs and in standardized workshops. X-SOLA represents the largest cross-sectional report within the thoracic community to date, demonstrating the penetration of VATS lobectomy for NSCLC internationally. From our study, we were able to identify a number of obstacles to broaden the adoption of this minimally invasive technique.

Pulmonary nodules smaller than 1 cm can be difficult to identify during minimally invasive resection, necessitating conversion to thoracotomy. We hypothesized that localizing nodules with electromagnetic navigation bronchoscopy and marking them with methylene blue would allow minimally invasive resection and reduce conversion to thoracotomy. We retrospectively identified all patients who underwent electromagnetic navigation bronchoscopy followed by minimally invasive resection of a pulmonary nodule from 2011 to 2014. Lung nodules smaller than 10 mm and nodules smaller than 20 mm that were also located more than 10 mm from the pleural surface were localized and marked with methylene blue. Immediately after marking, all patients underwent resection. Seventy patients underwent electromagnetic navigation bronchoscopy marking followed by minimally invasive resection. The majority of patients (68/70, 97%) had one nodule localized; 2 patients (2/70, 3%) had two nodules localized. The median nodule size was 8 mm (range, 4-17 mm; interquartile range, 5 mm). The median distance from the pleural surface was 6 mm (range, 1-19 mm; interquartile range, 6 mm). There were no conversions to thoracotomy. Nodule marking was successful in 70 of 72 attempts (97.2%); two nodules were identified by palpation. The nodules were most commonly metastases from other sites (31/70, 44.3%). There were no adverse events related to electromagnetic navigation bronchoscopy-guided marking or wedge resection, and minimal adverse events after resections that were more extensive. Localizing and marking small pulmonary nodules using electromagnetic navigation bronchoscopy is safe and effective for nodule identification before minimally invasive resection.

Background Tumors may induce systemic immune dysfunction, which can be aggravated by surgery and anesthesia/analgesia. Data on the effect of flurbiprofen preemptive analgesia on immune dysfunction is limited. The aim of this study was to investigate the effect of flurbiprofen preemptive analgesia on lymphocytes and natural killer (NK) cells in patients undergoing thoracotomy and thoracoscopy radical esophagectomy, and to explore the analgesic methods suitable for tumor patients. Methods This was a randomized controlled pilot study of 89 patients with esophageal cancer treated with surgery at the Henan Cancer Hospital between January 1, 2015 and December 31, 2016. The patients were divided into three groups: group 1, thoracotomy; group 2, thoracoscopy and laparoscopic surgery; and group 3, flurbiprofen, thoracoscopy, and laparoscopic surgery. CD3+, CD19+, NK, CD4+, and CD8+ cells in whole blood were measured by flow cytometry 30 minutes before surgery (T0), at the end of the thoracic section of the procedure (T1), and at the end of the operation (T2). Results There were no significant differences in CD3+, CD19+, CD8+, NK, and CD4+ cells between the three groups or regarding the time points during the procedure (all P > 0.05). Thoracotomy and thoracoscopy surgery resulted in similar immunological outcomes. Conclusion Flurbiprofen ester preemptive analgesia did not suppress the immune function in patients and could be a safe analgesic method for patients with esophageal cancer undergoing surgery.

2015-01-01

Postthoracotomy pain syndrome (PTPS) is a frequent cause of chronic postoperative pain. Pregabalin might reduce the incidence of chronic postoperative pain. The goal of this study was to evaluate the impact of perioperative pregabalin on the occurrence of PTPS, defined as any surgical site pain 3 months after surgery. We conducted a randomized, placebo-controlled, double-blind trial in patients undergoing elective thoracotomy. Patients received either pregabalin 150 mg orally twice a day initiated 1 hour before thoracotomy and continued until 4 days after thoracotomy (10 doses total) or a placebo using the same protocol. All patients received preincision thoracic epidural analgesia. Postthoracotomy pain syndrome was evaluated using the Brief Pain Inventory questionnaire through a telephone interview. Secondary outcomes included evaluation of neuropathic characteristics through the Leeds Assessment of Neuropathic Symptoms and Signs questionnaire, analgesic use 3 months after surgery, and evaluation of acute postoperative pain and opioid consumption. One hundred fourteen patients were randomized, and 99 patients completed the study (placebo, n = 49; pregabalin, n = 50). Postthoracotomy pain syndrome occurred in 49 (49.5%) of 99 patients and more frequently in the pregabalin group (31/50 [62%] vs 18/49 [37%] in the placebo group, P = 0.01). However, among patients with PTPS, those in the pregabalin group required significantly less analgesics, reported less moderate to severe average pain, and presented significantly less neuropathic characteristics than patients in the placebo group 3 months after surgery. Pregabalin did not reduce the incidence of PTPS in this study. Future research on PTPS should focus on the impact of regional analgesia on central sensitization.

Importance The value of robotically assisted surgery for mitral valve disease is questioned because the high cost of care associated with robotic technology may outweigh its clinical benefits. Objective To investigate conditions under which benefits of robotic surgery mitigate high technology costs. Design Clinical cohort study comparing costs of robotic vs. three contemporaneous conventional surgical approaches for degenerative mitral disease. Surgery was performed from 2006–2011, and comparisons were based on intent-to-treat, with propensity-matching used to reduce selection bias. Setting Large multi-specialty academic medical center. Participants 1,290 patients aged 57±11 years, 27% women, underwent mitral repair for regurgitation from posterior leaflet prolapse. Robotic surgery was used in 473, complete sternotomy in 227, partial sternotomy in 349, and anterolateral thoracotomy in 241. Three propensity-matched groups were formed based on demographics, symptoms, cardiac and noncardiac comorbidities, valve pathophysiology, and echocardiographic measurements: robotic vs. sternotomy (n=198 pairs) vs. partial sternotomy (n=293 pairs) vs. thoracotomy (n=224 pairs). Interventions Mitral valve repair. Main Outcome Measures Cost of care, expressed as robotic capital investment, maintenance, and direct technical hospital cost, and benefit of care, based on differences in recovery time. Results Median cost of care for robotically assisted surgery exceeded the cost of alternative approaches by 27% (−5%, 68%), 32% (−6%, 70%), and 21% (−2%, 54%) (median [15th, 85th percentiles]) for complete sternotomy, partial sternotomy, and anterolateral thoracotomy, respectively. Higher operative costs were partially offset by lower postoperative costs and earlier return to work: median 35 days for robotic surgery, 49 for complete sternotomy, 56 for partial sternotomy, and 42 for anterolateral thoracotomy. Resulting net differences in cost of robotic surgery vs. the three alternatives were 16% (−15%, 55%), 16% (−19%, 51%), and 15% (−7%, 49%), respectively. Beyond a volume threshold of 55–100 robotic cases per year, confidence limits for the cost of robotic surgery broadly overlapped those of conventional approaches. Conclusions In exchange for higher procedural costs, robotically assisted mitral valve surgery offers the clinical benefit of least invasive surgery, lowest postoperative cost, and fastest return to work. The value of robotically assisted surgery comparable to conventional approaches can only be realized in high-volume centers. PMID:24848944

A large animal model is required for the assessment of minimally invasive, tissue-engineering-based approaches to thoracic spine fusion, with relevance to deformity correction surgery for human adolescent idiopathic scoliosis. Here, we develop a novel open mini-thoracotomy approach in an ovine model of thoracic interbody fusion that allows the assessment of various fusion constructs, with a focus on novel, tissue-engineering-based interventions. The open mini-thoracotomy surgical approach was developed through a series of mock surgeries, and then applied in a live sheep study. Customized scaffolds were manufactured to conform with intervertebral disc space clearances that were required of the study. Six male Merino sheep aged 4-6 years and weighing 35-45 kg underwent the procedure mentioned earlier and were alloted a survival timeline of 6 months. Each sheep underwent a three-level discectomy (T6/7, T8/9, and T10/11) with a randomly allocated implantation of a different graft substitute at each of the following three levels: (1) polycaprolactone (PCL)-based scaffold plus 0.54 μg recombinant human bone morphogenetic protein-2 (rhBMP-2); (2) PCL-based scaffold alone; or (3) autograft. The sheep were closely monitored postoperatively for signs of pain (i.e., gait abnormalities/teeth gnawing/social isolation). Fusion assessments were conducted postsacrifice using computed tomography and hard-tissue histology. All scientific work was undertaken in accordance with the study protocol that was approved by the Institute's committee on animal research. All six sheep were successfully operated on and reached the allotted survival timeline, thereby demonstrating the feasibility of the surgical procedure and postoperative care. There were no significant complications and during the postoperative period, the animals did not exhibit marked signs of distress according to the previously described assessment criteria. Computed tomographic scanning demonstrated higher fusion grades in the rhBMP-2 plus PCL-based scaffold group in comparison to either PCL-based scaffold alone or autograft. These results were supported by a histological evaluation of the respective groups. This novel open mini-thoracotomy surgical approach to the ovine thoracic spine represents a safe surgical method that can reproducibly form the platform for research into various spine-tissue-engineered constructs and their fusion-promoting properties.

Recent literature has questioned the efficacy of routine detailed preoperative cardiac ischemia testing and preoperative cardiac intervention before noncardiac surgical procedures. We performed a retrospective review of patients undergoing thoracotomy (n = 294) between January of 1999 and January of 2005. The median age was 62 years. Detailed preoperative cardiac testing was performed on 184 patients (63%) and went beyond a thorough history, physical examination, and electrocardiogram to include at least one of the following: dobutamine stress echo (n = 116), nuclear stress test (n = 66), treadmill test (n = 8), and coronary angiogram (n = 40). Evidence for coronary disease was detected in 43% of tests (99/230) performed. Revascularization was performed in 10% of all patients (4/40) who underwent coronary angiography. Postoperative myocardial infarction occurred in 7 patients (2.4%) with 4 myocardial infarction-related mortalities. No significant difference was found in the incidence of myocardial infarction in patients with (n = 184) or without (n = 110) detailed preoperative cardiac testing (3.3% vs 0.9%, P = .29). Of the 4 patients (1.4%) who underwent revascularization to treat coronary lesions identified during prethoracotomy workup, 2 had a myocardial infarction, 1 of which was caused by thrombosis of a coronary stent. In the subset of patients who underwent lobectomy (n = 149), detailed cardiac testing was performed on 107 patients (72%). The incidence of myocardial infarction was similar in tested and untested patients (2.8% vs 2.4% respectively, P = 1.0). Selective use of detailed preoperative cardiac testing refines risk stratification and identifies patients for corrective cardiac interventions; however, it did not prove fully protective against myocardial infarction after thoracotomy in our study.

Patients undergoing minimally invasive cardiac surgery have the potential for significant pain from the thoracotomy site. We report the successful use of pectoral nerve block types I and II (Pecs I and II) as rescue analgesia in a patient undergoing minimally invasive mitral valve repair. In this case, a 78-year-old man, with no history of chronic pain, underwent mitral valve repair via right anterior thoracotomy for severe mitral regurgitation. After extubation, he complained of 10/10 pain at the incision site that was minimally responsive to intravenous opioids. He required supplemental oxygen because of poor pulmonary mechanics, with shallow breathing and splinting due to pain, and subsequent intensive care unit readmission. Ultrasound-guided Pecs I and II blocks were performed on the right side with 30 mL of 0.2% ropivacaine with 1:400,000 epinephrine. The blocks resulted in near-complete chest wall analgesia and improved pulmonary mechanics for approximately 24 hours. After the single-injection blocks regressed, a second set of blocks was performed with 266 mg of liposomal bupivacaine mixed with bupivacaine. This second set of blocks provided extended analgesia for an additional 48 hours. The patient was weaned rapidly from supplemental oxygen after the blocks because of improved analgesia. Pectoral nerve blocks have been described in the setting of breast surgery to provide chest wall analgesia. We report the first successful use of Pecs blocks to provide effective chest wall analgesia for a patient undergoing minimally invasive cardiac surgery with thoracotomy. We believe that these blocks may provide an important nonopioid option for the management of pain during recovery from minimally invasive cardiac surgery.

The study aim was to determine the safety and benefits of minimally invasive mitral valve surgery without aortic cross-clamping for mitral valve surgery after previous cardiac surgery. Between January 2006 and August 2008, a total of 90 consecutive patients (38 females, 52 males; mean age 66 +/- 9 years) underwent minimally invasive mitral valve surgery after having undergone previous cardiac surgery. Of these patients, 80 (89%) underwent mitral valve replacement and 10 (11%) mitral valve repair utilizing a small (5 cm) right lateral thoracotomy along the 4th or 5th intercostal space under fibrillatory arrest (mean temperature 28 +/- 2 degrees C). The predicted mortality, calculated using the Society of Thoracic Surgeons (STS) algorithm, was compared to the observed mortality. The mean ejection fraction was 45 +/- 13%, mean NYHA class 3 +/- 1, while 66 patients (73%) had previous coronary artery bypass grafting and 37 (41%) had previous valve surgery. Twenty-six patients (29%) underwent non-elective surgery. Cardiopulmonary bypass was instituted through axillary (n = 19), femoral (n = 70) or direct use aortic (n = 1) cannulation. Operative mortality was 2% (2/90), lower than the STS-predicted mortality of 7%. Three patients (3%) developed acute renal failure postoperatively, one patient (1%) required new-onset hemodialysis, and one (1%) developed postoperative stroke. No patients developed postoperative myocardial infarction. The mean postoperative packed red blood cell transfusion requirement at 48 h was 2 +/- 3 units. Minimally invasive right thoracotomy without aortic cross-clamping is an excellent alternative to conventional redo-sternotomy for reoperative mitral valve surgery. The present study confirmed that this technique is safe and effective in reducing operative mortality in high-risk patients undergoing reoperative cardiac surgery.

Video-assisted thoracoscopic surgery (VATS) lobectomy has recently become the recommended approach for stage I non-small cell lung cancer. However, these guidelines are not based on any large randomized control trial. Our study used propensity scores and a sensitivity analysis to compare VATS lobectomy with open thoracotomy. From 2005 to 2012, 24,811 patients (95.1%) were operated on by open thoracotomy and 1,278 (4.9%) by VATS. The end points were 30-day postoperative death, postoperative complications, hospital stay, overall survival, and disease-free survival. Two propensity scores analyses were performed: matching and inverse probability of treatment weighting, and one sensitivity analysis to unmask potential hidden bias. A subgroup analysis was performed to compare "high-risk" with "low-risk" patients. Results are reported by odds ratios or hazard ratios and their 95% confidence intervals. Postoperative death was not significantly reduced by VATS whatever the analysis. Concerning postoperative complications, VATS significantly decreased the occurrence of atelectasis and pneumopathy with both analysis methods, but there were no differences in the occurrence of other postoperative complications. VATS did not provide a benefit for high-risk patients. The VATS approach decreased the hospital length of stay from 2.4 days (95% confidence interval, -1.7 to -3 days) to -4.68 days (95% confidence interval, -8.5 to 0.9 days). Overall survival and disease-free survival were not influenced by the surgical approach. The sensitivity analysis showed potential biases. The results must be interpreted carefully because of the differences observed according to the propensity scores method used. A multicenter randomized controlled trial is necessary to limit the biases. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Surgical resection with curative intent is till the mainstay of treatment for resectable esophageal cancer. Minimal invasive oesophagectomy has the potential to lower morbidity and mortality. In all likelihood, thoracoscopic oesophagectomy in semiprone position gives all the benefits of prone position and can be converted to thoracotomy without change in patient position if needed. The aim of this study is to analyze the feasibility of thoracoscopic oesophagectomy in semiprone position. This is a retrospective analysis of the data of thoracoscopic oesophgeactomy in semiprone position at Kaizen Hospital, a tertiary care center for gastroenterology during the period of December 2011 to December 2012. All surgeries were performed under general anesthesia with a single-lumen endotracheal tube. Esophageal mobilization was done by thoracoscopic approach in a semiprone position and an end-to-end hand-sewn cervical anastomosis was done. Abdominal part was performed by laparoscopic method in 3 patients and by laparotomy in rest of the patients. Total of 12 patients were included in this study. There was 1 conversion to thoracotomy and 1 surgical mortality. Mean operating time for the thoracoscopic part was 103 minutes, mean estimated blood loss for the thoracoscopic part was 110 mL, mean maximum end-tidal CO2 38.5 mm Hg, mean lymph nodes retrieved 14, and all patients had R0 resection. The median intensive care unit stay was 1 day and hospital stay was 8 days. Thoracoscopic part of thoracolaparoscopic oesophagectomy in semiprone position is a feasible option. It gives all advantages of prone position and thoracotomy is possible without change in patient position. However, further large-scale studies are required.

The relationship between high volume and improved outcomes has been described for a host of elective high-impact, low-frequency procedures, but there are little data to support such a relationship in high-impact low-frequency procedures in trauma. Using emergency department thoracotomy (EDT) as a model, we hypothesized that patients presenting to centers with higher institutional volumes of EDT would have improved survival referent to those presenting to lower volume institutions. We queried the Pennsylvania Trauma Outcomes Study (PTOS) registry from 2007-2015 for all EDTs performed at level I and II centers identified by ICD-9 procedure codes and a location stamp indicating the emergency department. We examined patient-level risk factors for survival in univariate regression and multivariable regression models. Centers were divided into tertiles of mean annual EDT volume and the association between mean annual EDT volume and patient survival was examined using logistic regression after controlling for patient factors. 1,399 emergency department thoracotomies were performed at 28 centers. Overall survival was 6.8%. After controlling for patient age, mechanism of injury, signs of life, and injury severity, patients presenting to centers in the highest tertile of volume had significantly higher odds of survival compared to patients presenting to centers in the lowest tertile of volume (OR 4.56, 95% CI 1.43-14.50). Patients presenting to centers with higher mean annual volume of EDTs have improved survival compared to those presenting to institutions with lower mean annual EDT volume. Efforts to understand the etiology of this finding may lead to interventions to improve outcomes at lower volume centers. Level 3: Retrospective cohort study.

Epicardial implantable cardioverter-defibrillator (ICD) placement in infants, children, and patients with complex cardiac anatomy requires an open surgical thoracotomy and is associated with increased pain, longer length of stay, and higher cost. The purpose of this study was to compare an open surgical epicardial placement approach with percutaneous pericardial placement of an ICD lead system in an infant piglet model. Animals underwent either epicardial placement by direct suture fixation through a left thoracotomy or minimally invasive pericardial placement with thoracoscopic visualization. Initial lead testing and defibrillation threshold testing (DFT) were performed. After the 2-week survival period, repeat lead testing and DFT were performed before euthanasia. Minimally invasive placement was performed in 8 piglets and open surgical placement in 7 piglets without procedural morbidity or mortality. The mean initial DFT value was 10.5 J (range 3-28 J) in the minimally invasive group and 10.0 J (range 5-35 J) in the open surgical group (P = .90). After the survival period, the mean DFT value was 12.0 J (range 3-20 J) in the minimally invasive group and 12.3 J (range 3-35 J) in the open surgical group (P = .95). All lead and shock impedances, R-wave amplitudes, and ventricular pacing thresholds remained stable throughout the survival period. Compared with open surgical epicardial ICD lead placement, minimally invasive pericardial placement demonstrates an equivalent ability to effectively defibrillate the heart and has demonstrated similar lead stability. With continued technical development and operator experience, the minimally invasive method may provide a viable alternative to epicardial ICD lead placement in infants, children, and adults at risk of sudden cardiac death.

Following an analysis of current treatment strategies for spontaneous pneumothorax and their surrounding controversies, the paper reports the Authors' personal experience. From 1 January 1984 to 31 December 1989 a total of 76 cases of spontaneous pneumothorax were treated, of which 3 were bilateral. The M:F ratio was 9:1 and the age of patients ranged between 16 and 77 years (mean age 39.2); 22 cases were relapses (27.8%). Conservative therapy was used in 12 cases (15.1%); pleural drainage was introduced in 54 cases (68.3%) for a mean of 7.5 days. Fourteen thoracotomies were performed in 13 patients (10.4%): bullectomy was performed 10 times with stapler, whereas pleurodesis was obtained in 9 cases using pleural abrasion and in 5 cases using apical pleurectomy plus pleural abrasion. Axillary thoracotomy at the 5th space was most commonly used. No major complications were observed during the postoperative period and, in spite of the minimum follow-up of 3 months, no cases of relapse were observed in operated patients.

To observe the curative effects of platelet-rich plasma (PRP) combined with negative-pressure wound therapy (NPWT) on patients with sternal osteomyelitis and sinus tract after thoracotomy. Sixty-two patients with sternal osteomyelitis and sinus tract after thoracotomy, hospitalized from March 2011 to June 2015, were retrospectively analyzed. Based on whether receiving PRP or not, patients were divided into two groups, group NPWT ( 22 patients hospitalized from March 2011 to December 2012) and combination treatment group (CT, 40 patients hospitalized from January 2013 to June 2015). After debridement, patients in group NPWT were treated with continuous NPWT (negative pressure values from -15.96 to -13.30 kPa), while those in group CT were treated with PRP gel (blood platelet counts in PRP ranged from 1 450×10(9)/L to 1 800×10(9)/L, with 10-15 mL in each dosage) made on the surgery day to fill the sinus tract and wound, followed by NPWT. Negative pressure materials were changed every 5 days until 20 days after surgery in patients of both groups. PRP gel was replenished before changing of negative pressure materials in patients of group CT. The sinus tract sealing time, wound healing time, number of patients who had secondary repair surgery, number of patients who had recurrence of sinus tract within three months after wound healing, and length of hospital stay were recorded. Data were processed with t test, Fisher's exact test, and chi-square test. The sinus tract sealing time, wound healing time, and length of hospital stay in patients of group CT were (16±8), (27±13), and (43±13) d respectively, which were all significantly shorter than those in group NPWT [(29±14), (41±17), and (60±20) d, with t values from 3.88 to 4.67, P values below 0.01]. The number of patients who had secondary repair surgery in group CT was less than that in group NPWT (P<0.01). There was no statistically significant difference in the number of patients who had recurrence of sinus tract between two groups (P>0.05). Compared with NPWT only, PRP combined with NPWT has great curative effects on patients with sternal osteomyelitis and sinus tract after thoracotomy, for it shortens sinus tract sealing time, wound healing time, and length of hospital stay, and avoids the secondary repair surgery. This method is simple and safe with little injury.

Penetrating injuries to the chest present a frequent and challenging problem, but the majority of these injuries can be managed non-\\operatively. The aim of this study was to describe the incidence of penetrating chest trauma and the ultimate techniques used for operative management, as well as the diagnosis, complications, morbidity and mortality. A retrospective 9-year review of patients who underwent an operative procedure following penetrating chest trauma was performed. The mechanism of injury, gender, age, physiological and outcome parameters, including injury severity score (ISS), chest abbreviated injury scale (AIS) score, lung injury scale score, concomitant injuries, time from admission to operating room, transfusion requirement, indications for thoracotomy, intra-operative findings, operative procedures, length of hospital stay (LOS) and rate of mortality were recorded. A total of 1123 patients who were admitted with penetrating thoracic trauma were investigated. Of these, 158 patients (93 stabbings, 65 gunshots) underwent a thoracotomy within 24 h after the penetrating trauma. There were 146 (92.4%) male and 12 (7.6%) female patients, and their mean age was 25.72 9.33 (range, 15–54) years. The mean LOS was 10.65 8.30 (range, 5–65) days. Patients admitted after a gunshot had a significantly longer LOS than those admitted with a stab wound (gunshot, 13.53 9.92 days; stab wound, 8.76 6.42 days, p < 0.001). Patients who died had a significantly lower systolic blood pressure (SBP) on presentation in the emergency room (42.94 36.702 mm Hg) compared with those who survived (83.96 27.842 mm Hg, p = 0.001). The overall mortality rate was 10.8% (n = 17). Mortality for patients with stab wounds was 8/93 (8.6%) compared with 9/65 (13.8%) for patients with gunshot wounds (p = 0.29). Concomitant abdominal injuries (p = 0.01), diaphragmatic injury (p = 0.01), ISS (p = 0.001), chest AIS score (p < 0.05), ongoing output (p = 0.001), blood transfusion volume (p < 0.01) and SBP (p = 0.001) were associated with mortality. Penetrating injuries to the chest requiring a thoracotomy are uncommon, and lung-sparing techniques have become the most frequently used procedures for lung injuries. The presence of associated abdominal injuries increased the mortality five-fold. Factors that affected mortality were ISS, chest AIS score, SBP, ongoing chest output, blood transfusion volume, diaphragmatic injury and associated abdominal injury.

Respiratory foreign body aspiration (FBA) is a common global health problem requiring prompt recognition and early treatment to prevent potentially fatal complications. The majority of FBAs are due to organic objects and treatment is usually via either endoscopic or surgical extraction. FBA of a straight hairpin has been described as a unique entity in the literature, occurring most commonly in females, particularly during adolescence. In the process of inserting hairpins, the pins will typically be between the teeth with the head tilted backwards, while tying their hair with both hands. This position increases the risk of aspiration, particularly if there is any sudden coughing or laughing. To our knowledge, this is the first case report of a 35-mm straight metallic hairpin foreign body that has been successfully retrieved by a radiological snare system under fluoroscopic guidance. This was achieved with the use of a split endotracheal tube, and therefore avoided the need for a thoracotomy in an adolescent female patient.

Hospital de Urgencias. Córdoba. patients with blunt and penetrating chest trauma by stab wound, who need chest tube insertion and treated by only one surgeon, were evaluated from July 10 to December 31st 2000. Previously to the thoracostomy with 24 french tube in 5th intercostal space, at the affected side, a digital exploration of pleural cavity was done, attempting to find intrathoracic injuries. in a six months period, 36 thoracostomy tubes were placed, due thoracic trauma (11 blunt trauma and 25 penetrating, by stab wound). Three patients had positive findings in the digital exploration, which forced to do another diagnostic or therapeutic procedures. digital thoracotomy is not considered a formal procedure, but as a part of a technique, in which, the previous exploration with the finger before chest tube insertion, allows to reach a diagnosis of the pleural space situation, to confirm suspicions, to modify a conduct, and to avoid greater morbidity to patients.

General anesthesia combined with epidural anesthesia for thoracotomy due to spontaneous pneumothorax was given to a pregnant woman at 21st week of gestation. She was premedicated intravenously with famotidine 20 mg and metoclopramide 10 mg. Mepivacaine 1% was administered through a thoracic epidural catheter. General anesthesia was induced by thiamylal 225 mg, vecuronium 8 mg and fentanyl 100 mcg, and maintained by sevoflurane, vecuronium and fentanyl. Endobronchial intubation with a 35Fr Bronchocath double-lumen tube was successful and one-lung ventilation was commenced to maintain the end-expiratory CO2 pressure at 30 to 35 mmHg with Sp(O2) remaining 100%. Ephedrine 16mg (in 4mg increments) was required to maintain systolic blood pressure above 100 mmHg. After the surgery, ropivacaine 0.2% was administered through the catheter. There were no clinical signs of fetal distress during the perioperative period. Postoperative pregnancy and delivery were uneventful. We succeeded in the anesthetic management by avoiding hypoxia, hypercapnia, hypocapnia and hypotension during the surgery.

To highlight the importance of preventing visceral injury due to prominent anterior implants at the spinal column. A 52-year-old man with cord compression was treated with a T9/10 discectomy and instrumented fusion via a right thoracotomy and trans-pleural approach. Postoperatively, he had improved lower limb numbness. However, after a bout of coughing, there was sudden increase in chest drain output, hemodynamic instability and massive fluid collection in the right chest cavity. Emergency re-exploration of the thoracotomy was performed and a 6 cm laceration of the right postero-medial diaphragm was identified as the bleeding source and was found to be in close proximity with the locking nut of the anterior implants. The laceration was repaired and a soft synthetic patch was used to cover the implants. Postoperatively, the hemothorax resolved and the patient recovered from the neurological deficit. Prevention of diaphragmatic injury can be performed using lower profile and less sharp-edged implants. Implant coverage with a soft synthetic material is necessary if unable to perform direct repair of the parietal pleura over the implants.

Post-traumatic retained hemothorax is a major risk factor for empyema thoracis leading to prolonged hospitalization, entrapped lung and a need for decortication. VATS (Video Assisted Thoracoscopy) for retained hemothorax shortens the duration of chest tube drainage and length of stay. From December 2004 to July 2009, 110 consecutive patients underwent VATS for retained or clotted hemothoraces at the Department of Thoracic Surgery, Jinnah Postgraduate Medical Centre, Karachi. Majority of the patients were males (n = 91; 82.7%). Sixty-five patients (59.1%) underwent VATS within 6 days and 45 patients (40.9%) between 7 - 14 days of injury. In 8 patients (7.3%) VATS was abandoned for thoracotomy. Post VATS full lung expansion was achieved in 87 patients (79.0) with complete evacuation of hemothorax. Chest tubes were removed within the first week in 100 patients (90.9%). In hemodynamically stable patients, VATS is a safe, reliable and effective technique for the evacuation of retained hemothorax. Early intervention within 6 days of injury avoids the need for a thoracotomy and is associated with a better short and long-term outcome.

Right-sided congestive heart failure (CHF) developed secondary to severe pulmonary hypertension (PH) in an 8-year-old cat with a left-to-right shunting patent ductus arteriosus (PDA). Vascular reactivity was tested prior to shunt ligation by treatment with oxygen and sildenafil. This treatment was associated with a significant decrease in pulmonary artery pressure as assessed by echocardiography. Subsequently surgical shunt ligation was planned. During thoracotomy, digital occlusion of the PDA was performed for 10 min with simultaneous catheter measurement of right ventricular pressure, which did not increase. Permanent shunt ligation resulted in a complete and sustained clinical recovery. A lung biopsy sample obtained during thoracotomy demonstrated histopathological arterial changes typical of PH. Cats can develop clinically severe PH and right-sided CHF secondary to a left-to-right PDA even at an advanced age. Assuming there is evidence of pulmonary reactivity, PDA occlusion might be tolerated and can potentially produce long-term clinical benefits. Copyright © 2014 Elsevier B.V. All rights reserved.

Exsanguination following trauma is potentially preventable. Extremity tourniquets have been successfully implemented in military and civilian prehospital care. Prehospital control of bleeding from the torso and junctional area's remains challenging but offers a great potential to improve survival rates. This review aims to provide an overview of potential treatment options in both clinical as preclinical state of research on truncal and junctional bleeding. Since many options have been developed for application in the military primarily, translation to the civilian situation is discussed. Medline (via Pubmed) and Embase were searched to identify known and potential prehospital treatment options. Search terms were|: haemorrhage/hemorrhage, exsanguination, junctional, truncal, intra-abdominal, intrathoracic, intervention, haemostasis/hemostasis, prehospital, en route, junctional tourniquet, REBOA, resuscitative thoracotomy, emergency thoracotomy, pelvic binder, pelvic sheet, circumferential. Treatment options were listed per anatomical site: axilla, groin, thorax, abdomen and pelvis Also, the available evidence was graded in (pre) clinical stadia of research. Identified treatment options were wound clamps, injectable haemostatic sponges, pelvic circumferential stabilizers, resuscitative thoracotomy, resuscitative endovascular balloon occlusion of the aorta (REBOA), intra-abdominal gas insufflation, intra-abdominal self-expanding foam, junctional and truncal tourniquets. A total of 70 papers on these aforementioned options was retrieved. No clinical reports on injectable haemostatic sponges, intra-abdominal insufflation or self-expanding foam injections and one type of junctional tourniquets were available. Options to stop truncal and junctional traumatic haemorrhage in the prehospital arena are evolving and may offer a potentially great survival advantage. Because of differences in injury pattern, time to definitive care, different prehospital scenario's and level of proficiency of care providers; successful translation of various military applications to the civilian situation has to be awaited. Overall, the level of evidence on the retrieved adjuncts is extremely low.

 Minimally invasive left ventricular assist device (LVAD) implantation may reduce peri-/postoperative complications and risks associated with resternotomies. In this study, we describe our first results using a minimally invasive LVAD implantation technique (lateral thoracotomy [LT] group). These results were compared with LVAD implantations done via full median sternotomy (STX group).  HVAD (HeartWare, Framingham, Massachusetts, United States) implantations in 70 patients (LT group n  = 22, 52 ± 15 years old; STX group n  = 48, 59 ± 11 years old) were retrospectively analyzed. Minimally invasive access via left thoracotomy was feasible in 22 patients. Peri- and postoperative analyses of survival and adverse events were performed.  No survival differences were observed between the LT and STX group ( p  = 0.43). LT patients without temporary right ventricular assist device (tRVAD) showed a significantly better survival rate compared to LT patients with concomitant tRVAD implantation ( p  = 0.02), which could not be demonstrated in the STX group ( p  = 0.11). Two LT and four STX patients were successfully bridged to heart transplantation and three STX patients were successfully weaned with subsequent LVAD explantations. LVAD-related infections ( n  = 4 LT group vs n  = 20 STX group, p  = 0.04) were less likely in the LT group. No wound dehiscence occurred in the LT group, whereas five were observed in the STX group ( p  = 0.17). The amount of perioperative blood transfusions (within the first 7 postoperative days) did not differ in both study groups ( p  = 0.48).  The minimally invasive approach is a viable alternative with the possibility to reduce complications and should be particularly considered for bridge-to-transplant patients.

There are no guidelines regarding the surgical approach for spontaneous pneumothorax. It has been reported, however, that the risk of recurrence following video-assisted thoracic surgery is higher than that following open thoracotomy (OT). The objective of this study was to determine whether this higher risk of recurrence following video-assisted thoracic surgery could be attributable to differences in intraoperative parenchymal resection and the pleurodesis technique. Data for 7647 patients operated on for primary or secondary spontaneous pneumothorax between 1 January 2005 and 31 December 2012 were extracted from Epithor®, the French national database. The type of pleurodesis and parenchymal resection was collected. Outcomes were (i) bleeding, defined as postoperative pleural bleeding; (ii) pulmonary and pleural complications, defined as atelectasis, pneumonia, empyema, prolonged ventilation, acute respiratory distress syndrome and prolonged air leaks; (iii) in-hospital length of stay and (iv) recurrence, defined as chest drainage or surgery for a second pneumothorax. Of note, 6643 patients underwent videothoracoscopy and 1004 patients underwent OT. When compared with the thoracotomy group, the videothoracoscopy group was associated with more parenchymal resections (62.4 vs 80%, P = 0.01), fewer mechanical pleurodesis procedures (93 vs 77.5%, P < 10(-3)), fewer postoperative respiratory complications (12 vs 8.2%, P = 0.01), fewer cases of postoperative pleural bleeding (2.3 vs 1.4%, P = 0.04) and shorter hospital lengths of stay (16 vs 9 days, P = 0.01). The recurrence rate was 1.8% (n = 18) in the thoracotomy group versus 3.8% (n = 254) in the videothoracoscopy group (P = 0.01). The median time between surgery and recurrence was 3 months (range: 1-76 months). In the surgical management of spontaneous pneumothorax, videothoracoscopy is associated with a higher rate of recurrence than OT. This difference might be attributable to differences in the pleurodesis technique rather than differences in the parenchymal resection. © The Author 2015.

Following thoracotomy, patients frequently receive routine respiratory physiotherapy which may include incentive spirometry, a breathing technique characterised by deep breathing performed through a device offering visual feedback. This type of physiotherapy is recommended and considered important in the care of thoracic surgery patients, but high quality evidence for specific interventions such as incentive spirometry remains lacking. 180 patients undergoing thoracotomy and lung resection participated in a prospective single-blind randomised controlled trial. All patients received postoperative breathing exercises, airway clearance and early mobilisation; the control group performed thoracic expansion exercises and the intervention group performed incentive spirometry. No difference was observed between the intervention and control groups in the mean drop in forced expiratory volume in 1 s on postoperative day 4 (40% vs 41%, 95% CI -5.3% to 4.2%, p=0.817), the frequency of postoperative pulmonary complications (PPC) (12.5% vs 15%, 95% CI -7.9% to 12.9%, p=0.803) or in any other secondary outcome measure. A high-risk subgroup (defined by ≥2 independent risk factors; age ≥75 years, American Society of Anaesthesiologists score ≥3, chronic obstructive pulmonary disease (COPD), smoking status, body mass index ≥30) also demonstrated no difference in outcomes, although a larger difference in the frequency of PPC was observed (14% vs 23%) with 95% CIs indicating possible benefit of intervention (-7.4% to 2.6%). Incentive spirometry did not improve overall recovery of lung function, frequency of PPC or length of stay. For patients at higher risk for the development of PPC, in particular those with COPD or current/recent ex-smokers, there were larger observed actual differences in the frequency of PPC in favour of the intervention, indicating that investigations regarding the physiotherapy management of these patients need to be developed further.

The aim of this study is to describe implantation techniques and lead performance for biventricular pacing, dual-chamber implantable cardioverter defibrillators (ICDs). A dual-chamber ICD with biventricular pacing was implanted in 87 patients with congestive heart failure (ejection fraction: 0.21 +/- 0.09), prolonged QRS duration (161 +/- 22 msec), and an indication for ICD therapy. Left ventricular pacing was achieved with a thoracotomy approach (n = 21) or a nonthoracotomy approach (n = 66). With a thoracotomy, biventricular devices were implanted successfully in all patients. During follow-up (17 +/- 11 months), 9 patients died (43%), 2 underwent transplantation, and 2 required left ventricular lead revision. At last follow-up, biventricular sensing and capture threshold were 11 +/- 5 mV and 1.5 +/- 0.8 V, respectively. For nonthoracotomy procedures, two types of coronary sinus (CS) leads were implanted: an over-the-wire lead (n = 45) and a shaped lead (n = 21). The rate of successful implantation (overall: 89%) (over-the-wire 93% vs shaped 81%; P = 0.1) and durations for CS lead placement (66 +/- 50 vs 58 +/- 34 min, P = 0.6) and the procedure (133 +/- 58 vs 129 +/- 33 min, P = 0.8) were not different between the two CS leads. During follow-up (11 +/- 9 months), 9 patients died (14%), and the shaped CS lead dislodged in 3 patients (3 shaped vs 0 over-the-wire, P = 0.01). At last follow-up, biventricular sensing and capture threshold were 10 +/- 4 mV and 1.8 +/- 0.7 V, respectively, and there was no difference between over-the-wire and shaped leads. By multivariate analysis, mortality was associated with absence of spironolactone therapy but not procedural features. Nonthoracotomy CS lead implantation is feasible, with a success rate of about 90% and few adverse events. For the remaining 10%, a thoracotomy approach can be completed safely in these ill patients without increased risk for death.

CT-guided fine-needle biopsy of focal lung lesions as the method for reducing the number of invasive diagnostic procedures

Summary Background: CT-guided fine-needle biopsy (FNB) of focal lung lesions is one of the possibilities of obtaining histopathological diagnosis in pulmonary diseases. Its place in the algorithm is determined by the invasiveness. In case of no diagnosis after bronchoscopy or endobronchial ultrasonography (EBUS) guided biopsy, CT-guided FNB can become an alternative for more invasive procedures, such as open lung biopsy – thoracotomy. Material/Methods: Since January 2009 until February 2010, we performed 37 CT-guided FNB in 34 patients aged 31 to 76 (mean age 60.9). Among them, there were 16 women and 18 men. All patients underwent a standard chest CT with contrast medium injection. They were diagnosed with focal lesions and they were rejected from surgery as the primary method of treatment. During biopsy, the patient was positioned prone or supine, depending on the location of lesions. After performing a scout image and initial slices, we marked the level of biopsy, using a metal marker. Next, the biopsy needle was introduced under local anesthesia. When the obtained position of the needle in the lesion was correct, the specimen was taken. After needle removal, the patient was controlled for the presence of complications (i.e. pneumothorax). Biopsy time ranged from 10 to 50 minutes. Results: In 94.6% of biopsies, the specimens for histopathological and cytological examinations were obtained. In 22 (64.7%) patients, histopathological diagnoses (in 14 cases this was the non-small cell cancer and in 8, inflammatory lesions) were established which allowed us to resign from invasive thoracotomy and to introduce an appropriate treatment. In the remaining 12 patients, no diagnosis was established. Complications in the form of a minor pneumothorax occurred in 2 patients. Conclusions: Fine-needle biopsy of the focal lung lesions is an affective and a relatively safe method, which can replace the more invasive diagnostic thoracotomy in the majority of patients.

Thoracotomy results in severe postoperative pain potentially leading to chronic pain. We investigated the potential benefits of intravenous parecoxib on postoperative analgesia combined with thoracic epidural analgesia (TEA). Eighty-six patients undergoing thoracic surgery were randomized into two groups. Patient-controlled epidural analgesia (PCEA) was used until chest tubes were removed. Patients received parecoxib (group P) or placebo (group C) intravenously just 0.5 h before the operation and every 12 h after operation for 3 days. The intensity of pain was measured by using a visual analogue scale (VAS) and recorded at 2, 4, 8, 24, 48, 72 h after operation. The valid number of PCA, the side effects and the overall satisfaction to analgesic therapy in 72 h were recorded. Venous blood samples were taken before operation, the 1(st) and 3(rd) day after operation for plasma cortisol, adrenocorticotropic hormone (ACTH), interleukin-6 and tumor necrosis factor-α level. The occurrence of residual pain was recorded using telephone questionnaire 2 and 12 months after surgery. Postoperative pain scores at rest and on coughing were significantly lower with the less valid count of PCA and greater patient satisfaction in group P (P<0.01). Adverse effect and the days fit for discharge were comparable between two groups. The cortisol levels in placebo group were higher than parecoxib group at T2. The level of ACTH both decreased in two groups after operation but it was significantly lower in group P than that in group C. There were no changes in plasma IL-6 and TNF-α levels before and after analgesia at T1 and T2 (P>0.05). The occurrence of residual pain were 25% and 51.2% separately in group P and C 3 months postoperatively (P<0.05). Intravenous parecoxib in multimodal analgesia improves postoperative analgesia provided by TEA, relieves stress response after thoracotomy, and may restrain the development of chronic pain.

Video-assisted thoracic surgery (VATS) is currently performed to diagnose and treat solitary pulmonary nodules (SPN). However, the intra-operative identification of deep nodules can be challenging with VATS as the lung is difficult to palpate. The aim of the study was to report the utility and the results of pre-operative computed tomography (CT)-guided hook wire localization of SPN. All records of the patients undergoing CT-guided hook wire localization prior to VATS resection for SPN between 2002 and 2013 were reviewed. The efficacy in localizing the nodule, hook wire complications, necessity to convert VATS to thoracotomy and the histology of SPN are reported. One hundred eighty-one patients (90 females, mean age 63 y, range 28-82 y) underwent 187 pulmonary resections after CT-guided hook wire localization. The mean SPN diameter was 10.3 mm (range: 4-29 mm). The mean distance of the lesion from the pleural surface was 11.6 mm (range: 0-45 mm). The mean time interval from hook wire insertion to VATS resection was 224 min (range 54-622 min). Hook wire complications included pneumothorax requiring chest tube drainage in 4 patients (2.1%) and mild parenchymal haemorrhage in 11 (5.9%) patients. Migration of the hook wire occurred in 7 patients (3.7%) although it did not affect the success of VATS resection (nodule location guided by the lung puncture site). Three patients underwent additional wedge resection by VATS during the same procedure because no lesion was identified in the surgical specimen. Conversion thoracotomy was required in 13 patients (7 %) for centrally localized lesions (6 patients) and pleural adhesions (7 patients). The mean operative time was 60 min (range 18-135 min). Pathological examination revealed a malignant lesion in 107 patients (59 %). The diagnostic yield was 98.3 %. VATS resection for SPN after CT-guided hook wire localization for SPN is safe and allows for proper diagnosis with a low thoracotomy conversion rate.

To evaluate if the pre-emptive administration of ketamine would potentiate the effect of intravenous morphine analgesia in the management of post-thoracotomy pain. This was a unicentre, double-blind, placebo-controlled, parallel-group, prospective study. Patients were randomly assigned to receive 1 mg/kg ketamine (ketamine group) or an equivalent dose of normal saline (placebo group) before thoracotomy in 1:1 ratio. All patients received postoperatively intravenous morphine administration as additional analgesic regimen. Primary end-point was the pain relief measured with Visual Analogue Scale at rest. The secondary end-points were the reduction of inflammatory response expressed by plasma C-reactive protein levels, the morphine consumption and the rate of side effects. The measurements were carried out 6, 12, 24, 36 and 48 hours postoperatively. A total of 75 patients were randomized of whom 38 were allocated to ketamine group and 37 to placebo group. Baseline characteristics were comparable. Ketamine compared with placebo group showed a significant reduction of pain scores (P = 0.01), C-reactive protein (P < 0.001) and morphine consumption (P < 0.001). No acute psychological side effects related to the use of ketamine were registered. The administration of ketamine before surgery may be an effective adjunct to intravenous morphine analgesia in acute post-thoracotomy pain management. In ketamine group, satisfaction of pain relief was significantly higher with a significant reduction of inflammatory response and morphine consumption compared with placebo group. Our results, if confirmed by larger studies, may be of clinical relevance in situations where epidural analgesia or other analgesic procedures different from systemic opioid analgesia are unavailable or contraindicated. © The Author 2015.

2007-11-01

Vocal cord paralysis is one of the frequently encountered complications after aortic surgery. However, reports of vocal cord paralysis after aortic surgery have been limited. In a retrospective cohort study of vocal cord paralysis after aortic surgery at a general hospital, we sought factors related to its development after aortic surgery to the descending thoracic aorta via left posterolateral thoracotomy. We reviewed data for a total of 69 patients who, between 1989 and 1995, underwent aortic surgery to the descending thoracic aorta. We assessed factors associated with the development of vocal cord paralysis and postoperative complications. Postoperative vocal cord paralysis appeared in 19 patients. Multiple logistic regression analysis revealed two risk factors for vocal cord paralysis: chronic dilatation of the aorta at the left subclavian artery (odds ratio = 8.67) and anastomosis proximal to the left subclavian artery (odds ratio = 17.7). The duration of mechanical ventilation was significantly prolonged for patients with vocal cord paralysis. Certain surgical factors associated with left subclavian artery increase the risk of vocal cord paralysis after surgery on the descending thoracic aorta. Vocal cord paralysis after aortic surgery did not increase aspiration pneumonia but was associated with pulmonary complications.

Damage-control and emergency surgical procedures in trauma have the potential to save lives. They may occasionally not be performed due to clinician inexperience or lack of comfort and knowledge. Canadian Armed Forces (CAF) non-surgeon Medical Officers (MOs) participated in a live tissue training exercise. They received tele-mentoring assistance using a secure video-conferencing application on a smartphone/tablet platform. Feasibility of tele-mentored surgery was studied by measuring their effectiveness at completing a set series of tasks in this pilot study. Additionally, their comfort and willingness to perform studied procedures was gauged using pre- and post-study surveys. With no pre-procedural teaching, participants were able to complete surgical airway, chest tube insertion and resuscitative thoracotomy with 100% effectiveness with no noted complications. Comfort level and willingness to perform these procedures were improved with tele-mentoring. Participants felt that tele-mentored surgery would benefit their performance of resuscitative thoracotomy most. The use of tele-mentored surgery to assist non-surgeon clinicians in the performance of damage-control and emergency surgical procedures is feasible. More study is required to validate its effectiveness. Copyright © 2018 Elsevier Inc. All rights reserved.

Sternal approximation for bilateral anterolateral transsternal thoracotomy for lung transplantation.

The traditional incision for bilateral sequential lung transplantation is the bilateral anterolateral transsternal thoracotomy with approximation of the sternal fragments with interrupted stainless steel wire loops; this technique may be associated with an unacceptable incidence of postoperative sternal disruption causing chronic pain and deformity. Approximation of the sternal ends was achieved with peristernal cables that passed behind the sternum two intercostal spaces above and below the sternal division, which were then passed through metal sleeves in front of the sternum, the cables tensioned, and the sleeves then crimped. Forty-seven patients underwent sternal closure with this method, and satisfactory bone union occurred in all patients. Six patients underwent removal of the peristernal cables: 1 for infection (with satisfactory bone union after the removal of the cables), 3 for cosmetic reasons, 1 during the performance of a median sternotomy for an aortic valve replacement, and 1 in a patient who requested removal before commencing participation in football. This technique of peristernal cable approximation of sternal ends has successfully eliminated the problem of sternal disruption associated with this incision and is a useful alternative for preventing this complication after bilateral lung transplantation.

When retained hemothorax occurs, video-assisted thoracoscopy or thoracotomy is performed, but recently, tissue plasminogen activator (tPA) has been used. This study evaluated intrapleural tPA use for retained traumatic hemothoraces. A retrospective review was conducted of trauma patients treated with intrapleural tPA for retained hemothorax. Data included demographics, past medical and surgical histories, injury details, treatment details, and outcomes. Seven patients (median age = 47 years, male = 6, blunt trauma = 6) met study criteria. All patients received a chest tube. Six patients later received computed tomography-guided drains for tPA infusion. Number of tPA treatments per patient varied from 1 to 5. Median total tPA dosage was 24 mg. Median time from injury to chest tube placement was 11 days and from chest tube placement to first tPA treatment was 4 days. No patients required a video-assisted thoracoscopy; however, 1 patient required thoracotomy. There were no deaths or bleeding complications attributed to intrapleural tPA. Although future studies are needed to identify optimum treatment guidelines, intrapleural tPA appears to be a safe and efficacious treatment option. Copyright © 2014 Elsevier Inc.

Treatment of haemothorax.

PubMed

Boersma, Wim G; Stigt, Jos A; Smit, Hans J M

2010-11-01

Haemothorax is a problem commonly encountered in medical practice and is most frequently related to open or closed chest trauma or to invasive procedures of the chest. Spontaneous haemothorax is less common and can have various causes, such as the use of anticoagulants, neoplasia, and rupture of pleural adhesions. Identification by radiography and thoracentesis is indicated and treatment of the underlying trauma should start immediately. After insertion of a large chest tube, antibiotic prophylaxis in trauma patients should be administered for 24 h. Further treatment depends on the haemodynamic stability of the patient, the volume of evacuated blood and the occurrence of persistent blood loss. Surgical exploration by VATS or thoracotomy is necessary if >1.500 ml of blood has accumulated and/or an ongoing production of >200 ml of blood per hour is observed. If the haemorrhage is less severe, careful investigation into the underlying cause must be performed and blood should be evacuated by tube thoracostomy. If clotted blood retained in spite of tube thoracostomy, intrapleural fibrinolytic therapy can be applied to breakdown clots and adhesions. If conservative treatment is insufficient, a surgical approach with VATS or thoracotomy is indicated to prevent subsequent complications. Copyright © 2010 Elsevier Ltd. All rights reserved.

Rounded atelectasis is an uncommon but increasingly recognized benign form of peripheral lung collapse. The three patients described here had pleural-based lung masses considered initially to represent carcinoma. On computed tomography, a characteristics appearance of eight major and five minor signs of rounded atelectasis of the lung were found. In conjunction with other radiologic evaluations, these allowed the patients to be confidently managed without exploratory thoracotomy.

Although elderly patients with thoracic disease were considered to be poor candidates for thoracotomy before, recent advances in preoperative and postoperative care as well as surgical techniques have improved outcomes of thoracotomies in this patient group. The aim of this study was to investigate surgical risk factors and results in elderly patients (aged > or =70 years) with thoracic empyema. Seventy-one elderly patients with empyema thoracis were enrolled and evaluated from July 2000 to April 2003. The following characteristics and clinical data were analysed: age, sex, aetiology of empyema, comorbid diseases, preoperative conditions, postoperative days of intubation, length of hospital stay after surgery, complications and mortality. Surgical intervention, including total pneumonolysis and evacuation of the pleura empyema cavity, was carried out in all patients. Possible influent risk factors on the outcome were analysed. The sample group included 54 men and 17 women with an average age of 76.8 years. The causes of empyema included parapneumonic effusion (n = 43), lung abscess (n = 8), necrotizing pneumonitis (n = 8), malignancy (n = 5), cirrhosis (n = 2), oesophageal perforation (n = 2), post-traumatic empyema (n = 2) and post-thoracotomy complication (n = 1). The 30-day mortality rate was 11.3% and the in-hospital mortality rate was 18.3% (13 of 71). Mean follow up was 9.4 months and mean duration of postoperative hospitalization was 35.8 days. Analysis of risk factors showed that patients with necrotizing pneumonitis or abscess had the highest mortality rate (10 of 18, 62.6%). The second highest risk factor was preoperative intubation or ventilator-dependency (8 of 18, 44.4%). This study presents the clinical features and outcomes of 71 elderly patients with empyema thoracis who underwent surgical treatment. The 30-day surgical mortality rate was 11.3%. Significant risk factors in elderly patients with empyema thoracis were necrotizing pneumonitis, abscess and preoperative intubation/ventilation. This study also suggested that surgical treatment of empyema thoracic in elderly patients is recommended after failed conservative treatment because of the acceptably postoperative complication and mortality rate.

A chest-trauma management system, tagged as the "Pécs model" in a tertiary referral center is described with extensive references to the state of the art in thoracic trauma. Chest drainage has utmost importance in primary therapy as well as in surgical decision making (diagnosis). Thoracotomy is a general surgical competence, just as damage control is. Definitive treatment and management of sequelae, however, requires competence in thoracic surgery. Multidisciplinarity is underscored.

We sought to determine factors influencing survival and resource utilization in patients undergoing surgical resection of congenital lung malformations (CLM). Additionally, we used propensity score-matched analysis (PSMA) to compare these outcomes for thoracoscopic versus open surgical approaches. Kids' Inpatient Database (1997-2009) was used to identify congenital pulmonary airway malformation (CPAM) and pulmonary sequestration (PS) patients undergoing resection. Open and thoracoscopic CPAM resections were compared using PSMA. 1547 cases comprised the cohort. In-hospital survival was 97%. Mortality was higher in small vs. large hospitals, p<0.005. Survival, pneumothorax (PTX), and thoracoscopic procedure rates were higher, while transfusion rates and length of stay (LOS) were lower, in children ≥3 vs. <3months (p<0.001). Multivariate analysis demonstrated longer LOS for older patients and Medicaid patients (all p<0.005). Total charges (TC) were higher for Western U.S., older children, and Medicaid patients (p<0.02). PSMA for thoracoscopy vs. thoracotomy in CPAM patients showed no difference in outcomes. CLM resections have high associated survival. Children <3months of age had higher rates of thoracotomy, transfusion, and mortality. Socioeconomic status, age, and region were independent indicators for resource utilization. Extent of resection was an independent prognostic indicator for in-hospital survival. On PSMA, thoracoscopic resection does not affect outcomes. Copyright © 2016. Published by Elsevier Inc.

Inferior vena cava (IVC) injuries are associated with significant morbidity and mortality. To identify clinical factors associated with mortality in patients undergoing operative intervention for penetrating IVC injuries, a retrospective review of 98 patients was performed, excluding blunt injuries (n = 20) and deaths before surgery (n = 16). The overall mortality was 58 per cent. Nonsurvivors more commonly presented with hypotension (50% vs 23%, P = 0.03) and underwent resuscitative thoracotomy more frequently (42% vs 4%, P = 0.01). Retrohepatic injuries were more common among nonsurvivors (P = 0.04). There was no difference in the use of ligation (7% vs 17%, P = 0.29) or the massive transfusion protocol (35% vs 25%, P = 0.41). On multivariate analysis, after controlling for mechanism of injury, admission hypotension, Glasgow Coma Scale score , preoperative cumulative fluids, resuscitative thoracotomy , absence of spontaneous tamponade, and location of IVC injury, the only independent predictor of mortality was the absence of spontaneous tamponade at the time of laparotomy (odds ratio = 5.4, 95% confidence interval: 1.11-25.95; P = 0.04). Penetrating IVC injuries continue to be associated with a high mortality, particularly among patients with free intraabdominal hemorrhage at laparotomy. Large multicenter studies are required to define the optimal resuscitative and operative management techniques in these severely injured patients.

Limited data exist regarding indications for resuscitative emergency thoracotomy (ETR) in the pediatric population. We attempt to define the presenting hemodynamic parameters that predict survival for pediatric patients undergoing ETR. We reviewed all pediatric patients (age <18years), entered into the National Trauma Data Bank from 2007 to 2010, who underwent ETR within one hour of ED arrival. Mechanism of injury and hemodynamics were analyzed using Chi squared and Wilcoxon tests. 316 children (70 blunt, 240 penetrating) underwent ETR, 31% (98/316) survived to discharge. Less than 5% of patients survived when presenting SBP was ≤50mmHg or heart rate was ≤70bpm. For blunt injuries there were no survivors with a pulse ≤80bpm or SBP ≤60mmHg. When survivors were compared to nonsurvivors, blood pressure, pulse, and injury type were statistically significant when treated as independent variables and in a logistic regression model. When ETR was performed for SBP ≤50mmHg or for heart rate ≤70bpm less than 5% of patients survived. There were no survivors of blunt trauma when SBP was ≤60mmHg or pulse was ≤80bpm. This review suggests that ETR may have limited benefit in these patients. Copyright © 2014 Elsevier Inc. All rights reserved.

We describe two new resected cases of primary pulmonary hemangiopericytoma and the review of cases published in the period 1954-2002. The first patient has a large pulmonary mass of the right apex revealed by scapular pain. The right upper lobectomy with free margins reveals hemangiopericytoma. Pelvic and pulmonary metastases appear two years after surgery, treated by two series of chemotherapy without clinical response. After acute nephrotoxicity controlled by hemodialysis, the patient dies with distant metastases three years and an half after thoracotomy. The second patient develops dry cough and thoracic pain with discovery of a cavitary mass in the right pulmonary field. Fine needle aspiration cytology suggests a mesenchymatous lesion. Three months after extended pneumonectomy, the intrathoracic tumour relapses and regresses partially under chemotherapy. Femoral and brain metastases are irradiated. The patient dies 22 months after thoracotomy. Histology and immunohistochemistry of both tumours closely related to solitary fibrous tumour confirm malignant hemangiopericytoma. Primary pulmonary hemangiopericytoma is rare and may be benign or malignant. Radical resection is the best treatment. Chemotherapy and radiotherapy may improve the prognosis. Compared with lung cancer, the tumour is a slow growing mass, often voluminous, with delayed symptoms, very few lymph node dissemination, rare brain metastasis, more frequent cutaneous or retroperitoneal dissemination, often after long-term and requiring indeed a 10 to 20 years follow-up.

To report the successful surgical management (open mitral commissurotomy, OMC) of mitral stenosis (MS), incorporating heart-beating cardiopulmonary bypass (CPB), in a 1-year-old dog. Clinical case. One-year-old Cairn Terrier with MS. Diagnosis of MS was confirmed by means of 2-dimensional, continuous-wave and color-flow Doppler echocardiography. Surgery was performed through a left intercostal thoracotomy. CPB was initiated and the heart was kept beating. The fused commissures of the mitral valve were incised to free the cusps of the valve. Left intercostal thoracotomy allowed easy observation of the mitral orifice during heart-beating OMC. Persistent bleeding from the atriotomy site required a second surgical procedure after which the dog had an uneventful recovery. Echocardiography at 2 weeks and 1 year postoperatively indicated substantial improvement in left ventricular filling (pressure half-time=187 ms before surgery, 105 ms [2 weeks] and 110 ms [1 year] after surgery). Enlargement of the left atrium resolved; however, moderate mitral valve regurgitation was still present. MS can be successfully treated by OMC, facilitated by use of CPB. Substantial improvement in cardiac function was evident by ultrasound and Doppler examination postoperatively. OMC under heart-beating CPB should be considered for the treatment of MS in the dog.

The purpose of this study was to review ventilation and postoperative analgesic technics in 137 dogs and 13 cats with congenital or acquired heart disease. The animals were referred to the Department of Veterinary Clinical Sciences at The Ohio State University, U.S.A, for the following surgical interventions: correction of patent ductus arteriosus (PDA-ligation, 28%), cardiac catheterization with angiogram and angioplasty (22%), pacemaker implantation (18%), exploratory lateral thoracotomy (8.7%), correction of right aortic arch ring anomaly (3.3%), correction of subvalvular aortic stenosis (2.7%), correction of PDA with coil in patients with mitral regurgitation and congestive heart failure (2%), pericardectomy and removal of heart base tumor (2%), and palliative surgery for ventricular septal defect (VSD, 0.7%). Controlled ventilation was used in all animals during thoracotomy. Anesthesia was maintained over 2.3 +/- 1.3 hours by using either isoflurane, halothane, propofol, or diazepam-ketamine in 64%, 32%, 2%, and 0.7% of animals, respectively. Postoperative analgesia was necessary in 20% of animals and was provided by using different technics over several hours. The technics and respective percentages of animals in which they were used, were: intravenous buprenorphine (3.3%), intercostal nerve blocks (8.7%), epidural morphine (4%), and interpleural regional analgesia (4%).

Report of a rare case: occult hemothorax due to blunt trauma without obvious injury to other organs

PubMed Central

2013-01-01

Traumatic hemothorax commonly occurs accompanied by organ damage, such as rib fractures, lung injury and diaphragm rupture. Our reported patient was a 61-year-old man who fell down from a stepladder about 1 meter in height, resulting in a heavy blow to the left abdomen. He consulted a clinic because of left chest pain the next day and was transported to the emergency center of our hospital on diagnosis of hemothorax with hemorrhagic shock. On computed tomography scanning with contrast medium, left hemothorax without rib fracture, diaphragm rupture or obvious organ injury was evident. We found only bleeding to the thoracic space from a branch of the left inferior phrenic artery without involvement of the abdomen. The patient underwent percutaneous angiography and embolization for hemostasis, and subsequently thoracotomy in order to check the active bleeding and remove the hematoma to improve respiratory. As thoracotomy findings, we found damage of a branch of the left inferior phrenic artery to the thoracic space without diaphragm rupture, and sutured the lesion. Such active intervention followed by surgical procedures was effective and should be considered for rare occurrences like the present case. We must consider not only traumatic diaphragm rupture, but also vascular damage by pressure trauma as etiological factors for hemothorax. PMID:24176006

Treatments for esophageal cancer: a review.

PubMed

Kato, Hiroyuki; Nakajima, Masanobu

2013-06-01

Esophageal cancer is the eighth most common form of cancer worldwide. The treatments for esophageal cancer depend on its etiology. For mucosal cancer, endoscopic mucosal resection and endoscopic submucosal dissection are standard, while for locally advanced cancer, esophagectomy remains the mainstay. The three most common techniques for thoracic esophagectomy are the transhiatal approach, the Ivor Lewis esophagectomy (right thoracotomy and laparotomy), and the McKeown technique (right thoracotomy followed by laparotomy and neck incision with cervical anastomosis). Surgery for carcinoma of the cervical esophagus requires an extensive procedure with laryngectomy in many cases. When the tumor is more advanced, neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy is added. The theoretical advantages of adding chemotherapy to the treatment of esophageal cancer are potential tumor down-staging prior to surgery, as well as targeting micrometastases and, thus, decreasing the risk of distant metastasis. Cisplatin- and 5-fluorouracil-based regimes are used worldwide. Chemoradiotherapy is the standard for unresectable esophageal cancer and could also be considered as an option for resectable tumors. For patients who are medically or technically inoperable, concurrent chemoradiotherapy should be the standard of care. Although neoadjuvant chemoradiotherapy followed by surgery or salvage surgery after definitive chemoradiotherapy is a practical treatment; judicious patient selection is crucial. It is important to have a thorough understanding of these therapeutic modalities to assist in this endeavor.

Thoracic endometriosis is a rare entity characterized by presence of endometrial tissue in pleura, lung parenchyma or airways. Most frequent manifestations are catamenial pneumothorax, hemothorax, hemoptysis and pulmonary nodules. We report here a rare case of a woman with thoracic endometriosis who developed iterative pneumothorax and pneumopericardium on bilateral bullous pulmonary dystrophy. She was a 37-year-old woman without any tobacco exposure and with previous history of pleural tuberculosis treated 5 years earlier. She was first referred to our centre for right pleuro-pneumothorax and hemorrhagic ascites. Pleural fluid examinations did not show any tuberculosis relapse, the evolution was favorable after thoracic drainage and there was no parenchymal lung abnormality on CT scan after surgery. Celioscopic peritoneal examination revealed stage IV peritoneal endometriosis. One year later, she was admitted for left catamenial pneumothorax. Thoracic CT scan showed apparition of large subpleural bulla. She underwent thoracotomy for bulla resection and left partial pleurectomy. Two years later, she was hospitalized for right pneumothorax and compressive pneumopericardium. Surgical lung biopsies confirmed pleuropulmonary endometriosis. Thoracotomy was performed for talcage pleurodesis and diaphragmatic leakages sutures. Lung bulla are rare in thoracic endometriosis, mechanism of their formation remains unknown. Pericardial involvement is rare in endometriosis; we report here a unique case of pneumopericardium. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

Fellowship trainees in acute care surgery require experience in the management of complex and operative trauma cases. Trauma center staffing usually follows standard 12-hour or 24-hour shifts, with resident and fellow trainees following a similar schedule. Although trauma admissions can be generally unpredictable, we analyzed temporal trends of trauma patient arrival times to determine the best time frame to maximize trainee experience during each day. We reviewed 10 years (2007-2016) of trauma registry data for blunt and penetrating trauma activations. Hourly volumetric trends were observed, and three specific events were chosen for detailed analysis: (1) trauma activation with Injury Severity Score (ISS) greater than 15, (2) laparotomy for trauma, and (3) thoracotomy for trauma. A retrospective shift log was created, which included day (7:00 AM to 7:00 PM), night (7:00 PM to 7:00 AM), and swing (noon to midnight) shifts. A swing shift was chosen because it captures the peak volume for all three events. Means and 95% confidence intervals were calculated, and comparisons were made between shifts using the Wilcoxon matched-pairs signed rank test with Bonferroni correction, and p less than 0.05 considered significant. During the 10-year study period, 28,287 patients were treated at our trauma center. This included the evaluation and management of 7,874 patients with ISS greater than 15, performance of 1,766 laparotomies, and 392 thoracotomies for trauma. Swing shift was superior to both day and night shifts for ISS greater than 15 (p < 0.001). Both swing and night shifts were superior to day shift for laparotomies (p < 0.001). Swing shift was superior to both day shift (p < 0.001) and night shift (p = 0.031). Shifts with the highest yield of ISS greater than 15, laparotomies, and thoracotomies include night and swing shifts on Fridays and Saturdays. Projected experience of acute care surgery fellows in managing complex trauma patients increases with the integration of swing shifts into the schedule. Daily trauma volume follows a temporal pattern which, when used correctly, can increase trainee exposure to complex and operative trauma cases. We encourage other centers to analyze their volume and adjust trainee schedules accordingly to maximize their educational experience. Therapeutic study, level IV.

Does adding ketamine to morphine patient-controlled analgesia safely improve post-thoracotomy pain?

PubMed

Mathews, Timothy J; Churchhouse, Antonia M D; Housden, Tessa; Dunning, Joel

2012-02-01

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'is the addition of ketamine to morphine patient-controlled analgesia (PCA) following thoracic surgery superior to morphine alone'. Altogether 201 papers were found using the reported search, of which nine represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. This consisted of one systematic review of PCA morphine with ketamine (PCA-MK) trials, one meta-analysis of PCA-MK trials, four randomized controlled trials of PCA-MK, one meta-analysis of trials using a variety of peri-operative ketamine regimes and two cohort studies of PCA-MK. Main outcomes measured included pain score rated on visual analogue scale, morphine consumption and incidence of psychotomimetic side effects/hallucination. Two papers reported the measurements of respiratory function. This evidence shows that adding ketamine to morphine PCA is safe, with a reported incidence of hallucination requiring intervention of 2.9%, and a meta-analysis finding an incidence of all central nervous system side effects of 18% compared with 15% with morphine alone, P = 0.31, RR 1.27 with 95% CI (0.8-2.01). All randomized controlled trials of its use following thoracic surgery found no hallucination or psychological side effect. All five studies in thoracic surgery (n = 243) found reduced morphine requirements with PCA-MK. Pain scores were significantly lower in PCA-MK patients in thoracic surgery papers, with one paper additionally reporting increased patient satisfaction. However, no significant improvement was found in a meta-analysis of five papers studying PCA-MK in a variety of surgical settings. Both papers reporting respiratory outcomes found improved oxygen saturations and PaCO(2) levels in PCA-MK patients following thoracic surgery. We conclude that adding low-dose ketamine to morphine PCA is safe and post-thoracotomy may provide better pain control than PCA with morphine alone (PCA-MO), with reduced morphine consumption and possible improvement in respiratory function. These studies thus support the routine use of PCA-MK instead of PCA-MO to improve post-thoracotomy pain control.

Aortic occlusion is a potentially valuable tool for early resuscitation in patients nearing extremis or in arrest from severe hemorrhage. The American Association for the Surgery of Trauma's Aortic Occlusion in Resuscitation for Trauma and Acute Care Surgery registry identified trauma patients without penetrating thoracic injury undergoing aortic occlusion at the level of the descending thoracic aorta (resuscitative thoracotomy [RT] or zone 1 resuscitative endovascular balloon occlusion of the aorta [REBOA]) in the emergency department (ED). Survival outcomes relative to the timing of CPR need and admission hemodynamic status were examined. Two hundred and eighty-five patients were included: 81.8% were males, with injury due to penetrating mechanisms in 41.4%; median age was 35.0 years (interquartile range 29 years) and median Injury Severity Score was 34.0 (interquartile range 18). Resuscitative thoracotomy was used in 71%, and zone 1 REBOA in 29%. Overall survival beyond the ED was 50% (RT 44%, REBOA 63%; p = 0.004) and survival to discharge was 5% (RT 2.5%, REBOA 9.6%; p = 0.023). Discharge Glasgow Coma Scale score was 15 in 85% of survivors. Prehospital CPR was required in 60% of patients with a survival beyond the ED of 37% and survival to discharge of 3% (all p > 0.05). Patients who did not require any CPR before had a survival beyond the ED of 70% (RT 48%, REBOA 93%; p < 0.001) and survival to discharge of 13% (RT 3.4%, REBOA 22.2%, p = 0.048). If aortic occlusion patients did not require CPR but presented with hypotension (systolic blood pressure <90 mmHg; 9% [65% RT; 35% REBOA]), they achieved survival beyond the ED in 65% (p = 0.009) and survival to discharge of 15% (RT 0%, REBOA 44%; p = 0.008). Overall, REBOA can confer a survival benefit over RT, particularly in patients not requiring CPR. Considerable additional study is required to definitively recommend REBOA for specific subsets of injured patients. Copyright © 2018 American College of Surgeons. Published by Elsevier Inc.

Mycotic pseudoaneurysm of the pulmonary artery that ruptures during necrotizing pneumonia is a rare entity that is often fatal. Traditionally it has been treated with open thoracotomy and resection of both the aneurysm and the lobe in which the aneurysm is located. In this report, we describe the radiological findings and transcatheter coil embolization of a mycotic pulmonary pseudoaneurysm in a 6-month-old female infant. We also describe the subsequent morphologic changes observed on follow-up computed tomography after 9 months of embolization.

A successful retrieval of a detached segment of a CVP catheter by percutaneous right transfemoral venous route, using a Dotter intravascular retriever basket, is reported. The procedure was monitored under fluoroscopy. Only local anaesthesia, which was infiltrated around the puncture site, was given to the patient. No significant complication was encountered. Successful retrieval of the detached catheter fragment by percutaneous means obviates the need for thoracotomy.

Etoricoxib - preemptive and postoperative analgesia (EPPA) in patients with laparotomy or thoracotomy - design and protocols

PubMed Central

2010-01-01

Background and Objective Our objective was to report on the design and essentials of the Etoricoxib protocol- Preemptive and Postoperative Analgesia (EPPA) Trial, investigating whether preemptive analgesia with cox-2 inhibitors is more efficacious than placebo in patients who receive either laparotomy or thoracotomy. Design and Methods The study is a 2 × 2 factorial armed, double blinded, bicentric, randomised placebo-controlled trial comparing (a) etoricoxib and (b) placebo in a pre- and postoperative setting. The total observation period is 6 months. According to a power analysis, 120 patients scheduled for abdominal or thoracic surgery will randomly be allocated to either the preemptive or the postoperative treatment group. These two groups are each divided into two arms. Preemptive group patients receive etoricoxib prior to surgery and either etoricoxib again or placebo postoperatively. Postoperative group patients receive placebo prior to surgery and either placebo again or etoricoxib after surgery (2 × 2 factorial study design). The Main Outcome Measure is the cumulative use of morphine within the first 48 hours after surgery (measured by patient controlled analgesia PCA). Secondary outcome parameters include a broad range of tests including sensoric perception and genetic polymorphisms. Discussion The results of this study will provide information on the analgesic effectiveness of etoricoxib in preemptive analgesia and will give hints on possible preventive effects of persistent pain.

Control group patients (n=102) received standard medical/nursing care, and experimental group patients (n=106) added to the standard clinical pathway a daily physiotherapy program focused on respiratory exercises until discharge. Analyzed outcomes were the frequency of postoperative pulmonary complications (PPCs) more amenable to physiotherapy (pneumonia, atelectasis and respiratory insufficiency) and length of hospital stay (LOS). Both groups were comparable regarding preoperative and surgical characteristics. Incidence of PPCs was 20.6% in control and 6.6% in experimental group (P=.003). Median (IQR) LOS in control group was 14 (7) days (Huber M estimator 14.21) and 12 (6) days (Huber M estimator 12.81) in experimental. Logistic regression model identified the evaluated physiotherapy program (P=.017; EXP [B] 95% CI 0.081-0.780) and % FEV1 (P=.042; EXP [B] 95% CI 0.941-0.999) as protective factors for the development of PPCs in patients undergoing lobectomy. Implementing a postoperative intensive physiotherapy program focused on respiratory exercises reduces the risk of PPCs and resultant LOS on patients undergoing lobectomy. Copyright © 2016 SEPAR.

Acute ipsilateral shoulder pain (ISP) is a common complaint in patients after thoracotomy. The incidence ranges from 21% to 97%. Unfortunately, clinical studies did not put enough focus on ISP post thoracic surgery. This study was designed to compare the effectiveness of suprascapular nerve block (SNB) and phrenic nerve infiltration (PNI) for controlling ISP. One hundred and thirty-five lung cancer patients (135) scheduled for open-lung surgery were randomly allocated into three equal groups; control group: received thoracic epidural with general anesthesia, suprascapular group: (SNB) one hour before the operation with 10 ml bupivacaine plus thoracic epidural with general anesthesia and phrenic nerve group: (PNI) was performed by the operating surgeon with 10 ml bupivacaine plus thoracic epidural with general anesthesia. The visual analogue score (VAS) of ISP, rescue of ketorolac for break through shoulder pain, peak expiratory flow rate (PEFR) and arterial blood gases were measured every 6 h postoperatively for 48 h. The VAS, rescue doses of ketorolc and PEFR were significantly lower in the phrenic nerve group (P-value <0.05). There was no statistically significant difference between the three groups postoperatively as regards arterial blood gases (P-value >0.05). PNI is more effective than SNB for ISP.

Transmediastinal gunshot wounds are associated with a high mortality and frequently require operative intervention. The purpose of this study was to identify the diagnostic and therapeutic challenges of these injuries in a mature trauma system with decreasing prehospital time intervals. Patients admitted to a large urban Level 1 trauma centre between 1/2006 and 12/2010 sustaining a firearm injury to the torso were identified. Transmediastinal gunshot wounds were defined as missile tracts traversing the mediastinum identified on CT images, operative notes or autopsy reports. Overall, 133 patients met study criteria. A total of 116 patients (87.2%) were haemodynamically unstable or had no vital signs on arrival to the Emergency Department. Ninety-seven (83.6%) of these patients required a resuscitative thoracotomy resulting in 8 survivors (6.0%). There were 17 haemodynamically stable patients (12.8%) identified, 14 of whom underwent CT scan evaluation. Six patients subsequently required operative intervention. Only 11 patients (8.3%) in the study population were successfully managed nonoperatively. The overall mortality was 78.9%, and for those who reached the hospital with vital signs, the mortality was 24.3%. Transmediastinal gunshot wounds encountered in a mature trauma centre are highly lethal injuries requiring resuscitative thoracotomy in most instances. Changing perspectives in these injuries may reflect the effects of an evolving prehospital care. Copyright © 2012 Elsevier Ltd. All rights reserved.

Thorascopic resection of an apical paraspinal schwannoma using the da Vinci surgical system.

2014-01-01

Posterior mediastinal neurogenic tumors have traditionally been resected via an open posterolateral thoracotomy. Video-assisted thorascopic surgery has emerged as an alternative technique allowing for improved morbidity with decreased blood loss, less postoperative pain, and a shorter recovery period, among others. The da Vinci surgical system, as first described for urologic procedures, has recently been reported for lung lobectomy. This technique provides the advantages of instrumentation with 6 degrees of freedom, stable operating arms, and improved visualization with the three-dimensional high-definition camera. We describe the technique for thorascopic resection of an apical paraspinal schwannoma of the T1 nerve root with the da Vinci surgical system. This technique used a specialized intraoperative neuromonitoring probe for free-running electromyography (EMG) and triggered EMG. We demonstrate successful resection of a posterior paraspinal schwannoma with the da Vinci surgical system while preserving neurologic function. The patient displayed stable intraoperative monitoring of the T1 nerve root and full intrinsic hand strength postoperatively. The technique described in this article introduces robotic system accuracy and precludes the need for an open thoracotomy. In addition, this approach demonstrates the ability of the da Vinci surgical system to safely dissect tumors from their neural attachments and is applicable to other such lesions of similar size and location.

Although surgical outcomes of total arch replacement have improved, the strategy for extended arch aneurysms remains controversial. We have applied the L-incision approach (combination of left anterior thoracotomy and upper half-median sternotomy) for total arch replacement for single-stage repair of extensive arch aneurysms. We retrospectively reviewed the operative outcomes of patients who underwent total arch or extended total arch replacement for degenerative aneurysms from 1999 to 2010. Operations were performed via median sternotomy in 47 patients (M group) and the L-incision approach was used in 38 patients (L group). Through the L-incision approach, we were able to complete distal anastomosis below the pulmonary hilus. The L-incision approach has advantages of reducing selective antegrade cerebral perfusion and lower body circulatory arrest times compared with the M group. Recurrent laryngeal nerve palsy and renal dysfunction were less frequent in the L group than those in the M group. Respiratory dysfunction and wound infection were similar between the groups. Hospital mortalities were 5.3% in the L group and 6.4% in the M group. The L-incision approach has similar or better postoperative outcomes compared with the median sternotomy approach. This approach could be useful for single-stage extended total arch replacement with relatively low risk.

Liposarcoma is the single most common soft tissue sarcoma. Because mediastinal liposarcomas often grow rapidly and frequently recur locally despite adjuvant chemotherapy and radiotherapy, they require complete excision. Therefore, the feasibility of achieving complete surgical excision must be carefully considered. We here report a case of a huge mediastinal liposarcoma resected via clamshell thoracotomy. A 64-year-old man presented with dyspnea on effort. Cardiomegaly had been diagnosed 6 years previously, but had been left untreated. A computed tomography scan showed a huge (36 cm diameter) anterior mediastinal tumor expanding into the pleural cavities bilaterally. The tumor comprised mostly fatty tissue but contained two solid areas. Echo-guided needle biopsies were performed and a diagnosis of an atypical lipomatous tumor was established by pathological examination of the biopsy samples. Surgical resection was performed via a clamshell incision, enabling en bloc resection of this huge tumor. Although there was no invasion of surrounding organs, the left brachiocephalic vein was resected because it was circumferentially surrounded by tumor and could not be preserved. The tumor weighed 3500 g. Pathologic examination of the resected tumor resulted in a diagnosis of a biphasic tumor comprising dedifferentiated liposarcoma and non-adipocytic sarcoma with necrotic areas. The patient remains free of recurrent tumor 20 months postoperatively. Clamshell incision provides an excellent surgical field and can be performed safely in patients with huge mediastinal liposarcomas.

Patients who suffer a cardiac arrest from trauma rarely survive, even with aggressive resuscitation attempts, including an emergency department thoracotomy. Emergency Preservation and Resuscitation (EPR) was developed to utilize hypothermia to buy time to obtain hemostasis before irreversible organ damage occurs. Large animal studies have demonstrated that cooling to tympanic membrane temperature 10°C during exsanguination cardiac arrest can allow up to 2 hours of circulatory arrest and repair of simulated injuries with normal neurologic recovery. The Emergency Preservation and Resuscitation for Cardiac Arrest from Trauma trial has been developed to test the feasibility and safety of initiating EPR. Select surgeons will be trained in the EPR technique. If a trained surgeon is available, the subject will undergo EPR. If not, the subject will be followed as a control subject. For this feasibility study, 10 EPR and 10 control subjects will be enrolled. Study participants will be those with penetrating trauma who remain pulseless despite an emergency department thoracotomy. Emergency Preservation and Resuscitation will be initiated via an intra-aortic flush of a large volume of ice-cold saline solution. Following surgical hemostasis, delayed resuscitation will be accomplished with cardiopulmonary bypass. The primary outcome will be survival to hospital discharge without significant neurologic deficits. Secondary outcomes include long-term survival and functional outcome. Once data from these 20 subjects are reviewed, revisions to the inclusion criteria and/or the EPR technique may then be tested in a second set of EPR and control subjects.

Uniportal video-assisted thoracoscopic surgery: safety, efficacy and learning curve during the first 250 cases in Quebec, Canada.

Video-assisted thoracoscopic surgery (VATS) using a single incision (uniportal) may result in better pain control, earlier mobilization and shorter hospital stays. Here, we review the safety and efficiency of our initial experience with uniportal VATS and evaluate our learning curve. We conducted a retrospective review of uniportal VATS using a prospectively maintained departmental database and analyzed patients who had undergone a lung anatomic resection separately from patients who underwent other resections. To assess the learning curve, we compared the first 10 months of the study period with the second 10 months. From January 2014 to August 2015, 250 patients underwent intended uniportal VATS, including 180 lung anatomic resections (72%) and 70 other resections (28%). Lung anatomic resection was successfully completed using uniportal VATS in 153 patients (85%), which comprised all the anatomic segmentectomies (29 patients), 80% (4 of 5) of the pneumonectomies and 82% (120 of 146) of the lobectomies attempted. The majority of lung anatomic resections that required conversion to thoracotomy occurred in the first half of our study period. Seventy patients underwent other uniportal VATS resections. Wedge resections were the most common of these procedures (25 patients, 35.7%). Although 24 of the 70 patients (34%) required the placement of additional ports, none required conversion to thoracotomy. Uniportal VATS was safe and feasible for both standard and complex pulmonary resections. However, when used for pulmonary anatomic resections, uniportal VATS entails a steep learning curve.

To test the effects of pressure-controlled (PCV) and volume-controlled (VCV) ventilation during one-lung ventilation (OLV) for thoracic surgery on right ventricular (RV) function. A prospective, randomized, double-blind, controlled, crossover study. A single university hospital. Fourteen pairs of consecutive patients scheduled for elective thoracotomy. Patients were assigned randomly to ventilate the dependent lung with PCV or VCV mode, each in a randomized crossover order using tidal volume of 6 mL/kg, I: E ratio 1: 2.5, positive end-expiratory pressure (PEEP) of 5 cm H2O and respiratory rate adjusted to maintain normocapnia. Intraoperative changes in RV function (systolic and early diastolic tricuspid annular velocity (TAV), end-systolic volume (ESV), end-diastolic volume (EDV) and fractional area changes (FAC)), airway pressures, compliance and oxygenation index were recorded. The use of PCV during OLV resulted in faster systolic (10.1±2.39 vs. 5.8±1.67 cm/s, respectively), diastolic TAV (9.2±1.99 vs. 4.6±1.42 cm/s, respectively) (p<0.001) and compliance and lower ESV, EDV and airway pressures (p<0.05) than during the use of VCV. Oxygenation indices were similar during the use of VCV and PCV. The use of PCV offers more improved RV function than the use of VCV during OLV for open thoracotomy. These results apply specifically to younger patients with good ventricular and pulmonary functions. © 2014 Elsevier Inc. All rights reserved.

Video-assisted thoracic surgery appears to be technically difficult for segmentectomy. Conversely, robotic surgery could facilitate the performance of segmentectomy. The aim of this study was to compare the early results of video- and robot-assisted segmentectomies. Data were collected prospectively on videothoracoscopy from 2010 and on robotic procedures from 2013. Fifty-one patients who were candidates for minimally invasive segmentectomy were included in the study. Perioperative outcomes of video-assisted and robotic segmentectomies were compared. The minimally invasive segmentectomies included 32 video- and 16 robot-assisted procedures; 3 segmentectomies (2 video-assisted and 1 robot-assisted) were converted to lobectomies. Four conversions to thoracotomy were necessary for anatomical reason or arterial injury, with no uncontrolled bleeding in the robotic arm. There were 7 benign or infectious lesions, 9 pre-invasive lesions, 25 lung cancers, and 10 metastatic diseases. Patient characteristics, type of segment, conversion to thoracotomy, conversion to lobectomy, operative time, postoperative complications, chest tube duration, postoperative stay, and histology were similar in the video and robot groups. Estimated blood loss was significantly higher in the video group (100 vs. 50 mL, p = 0.028). The morbidity rate of minimally invasive segmentectomy was low. The short-term results of video-assisted and robot-assisted segmentectomies were similar, and more data are required to show any advantages between the two techniques. Long-term oncologic outcomes are necessary to evaluate these new surgical practices. © The Author(s) 2016.

Acute rupture of the descending thoracic aorta: repair with use of endovascular stent-grafts.

To describe the use of endovascular stent-grafts to treat acute ruptures of the descending thoracic aorta as an alternative to surgery in high-risk patients. From July 1992 to August 1996, 95 patients underwent stent-grafting of the descending thoracic aorta for a variety of lesions. Of these, 11 patients with acute (< or = 7 days) rupture from aneurysms (n = 8) or trauma (n = 3) underwent repair with use of endovascular stent-grafts. Rupture was confirmed with preoperative imaging studies and occurred in the mediastinum (n = 9), the pleural space (n = 1), or the lung (n = 1). All patients were considered high surgical risk due to generalized cardiopulmonary disease and/or previous thoracotomies. Stent-grafts were constructed from Z stents covered with polyester fabric and delivered through a catheter under fluoroscopic control from a remote access site. Stent-graft deployment was successful in all patients. There were no complications of perigraft leak, stent migration, paraplegia, or intraoperative death. Two patients died in the follow-up period: one of ventricular perforation during unrelated thoracic surgery for tumor resection (day 1) and one of cardiac arrest (day 28). All others are alive (mean follow-up, 15.1 months). For acute rupture of the thoracic aorta, endovascular stent-graft repair is technically feasible and may be a therapeutic alternative to a surgical interposition graft in patients considered high risk for conventional thoracotomy. Long-term studies are necessary to determine the role of stent-grafts in preventing future aortic rupture.

The purpose of this study was to evaluate the efficacy of our subcostal closure technique in prevention of postthoracotomy pain syndrome. From July 2012 to March 2015, 29 patients in whom a lobectomy was indicated underwent a thoracotomy. The thoracotomy wounds were closed using a subcostal closure technique (subcostal closure group) and outcomes were compared with 31 patients who underwent video-assisted thoracoscopic surgery (thoracoscopy group). The duration of oral opioid consumption was evaluated from medical records, and postoperative pain was evaluated by telephone interview conducted by a trained nurse practitioner who was unaware of the patient's group. Pain scores were higher in the thoracoscopy group compared to the subcostal closure group, reaching statistical significance (Numeric Rating Scale 0.55 ± 0.948 in the subcostal closure group vs. 1.84 ± 1.614 in the thoracoscopy group; p < 0.001, Clinical Pain Scale 0.24 ± 0.435 in the subcostal closure group vs. 0.81 ± 0.703 in the thoracoscopy group; p < 0.001). The number of patients who consumed oral opioids for longer than 2 months after the operation was significantly greater in the thoracoscopy group than the subcostal closure group (6.9% in the subcostal closure group vs. 32.3% in the thoracoscopy group; p = 0.022). The subcostal closure technique is useful to prevent postthoracotomy pain syndrome. © The Author(s) 2016.

The association between thymic tumors and other intrathoracic or extrathoracic neoplasms is relatively rare; the synchronous occurrence of thymoma and bronchoalveolar carcinoma of the lung has never been described so far. A huge B3 cystic thymoma was found at thoracotomy to be associated with stage IV bronchoalveolar carcinoma (intraparenchymal and pleural metastases). The thymic tumor was completely resected; lung cancer was biopsied only for diagnosis and staging purposes. After an uneventful postoperative course the patient underwent chemotherapy; she is still alive and well one year after surgery.

The present paper describes experimental and clinical studies of a new method "Apicoaortic-PA" cannulation for mitral valve surgery. Our experimental study showed that this method was more rapid and more physiological for cardiopulmonary bypass. We used this technique in 55 cases of isolated mitral valve surgery with successful results. Our general philosophy of surgical approach to the mitral valve diseases is also discussed. We advocate the utilization of the "Apicoaortic Pulmonary Artery" cannulation method for clinical use in isolated mitral valve surgery through the left thoracotomy.

Management of pyothorax.

PubMed

Holmberg, D L

1979-05-01

Pyothorax is a serious disease process which requires both medical and surgical intervention. Late recognition, management problems, and likely recurrence make successful treatment difficult and often frustrating. Aims of therapy should be to avoid undue stress to the patient, to relieve respiratory distress by thoracocentesis, to eliminate infectious agents with antimicrobials, to remove pleural exudate, and to provide supportive care. Close monitoring of the patient is necessary to prevent iatrogenic complications such as pneumothorax, hemothorax, hypothermia, or hypoproteinemia. Exploratory thoracotomy for removal of granulomatous material and fibroelastic pleural "peels" is occasionally necessary to resolve compressive cardiopulmonary lesions.

Mitral regurgitant indexes were measured by roentgen videodensitometry in anesthetized dogs without thoracotomy before, during and after extrasystolic potentiation of ventricular contraction while the atria and ventricles were driven in normal temporal sequence simultaneously or in such a way as to induce atrial fibrillation. Small amounts of mitral reflux were observed with simultaneous atrial and ventricular driving and with atrial fibrillation in the control measurements before initiation of extrasystolic potentiation. Reflux became negligible during extrasystolic potentiation and increased beyond control levels after termination of extrasystolic potentiation.

Our experience with 17 patients with spinal cord injuries (SCI) acquired in the Lebanon War, 1982, is described. The SCI were due to gunshot wounds in 12 patients and to other causes in 5. Two laparotomies and one thoracotomy were performed. Corticosteroids were not seen to influence recovery, nor was laminectomy, which was performed in three cases. Complications such as pressure sores, hydronephrosis, ileus and deep vein thrombosis were rare or did not occur. Three high quadriplegics died. Based on our experience, we recommend conservative treatment and rehabilitation in acute SCI.

We present an unusual case of right lower lobe intralobar pulmonary sequestration in a previously healthy and physical active 27-year-old U.S. Marine, who presented with new onset hemoptysis after doing push-ups. Diagnosis was obtained by chest X-ray and contrast computed tomography scan. Preoperatively the patient underwent fluoroscopy-guided embolization of the aberrant systemic artery supplying the sequestration. The segmental resection of the sequestration was then successfully performed through a muscle-sparing thoracotomy. Reprint & Copyright © 2014 Association of Military Surgeons of the U.S.

Beneficial effects of glutamine on wound healing are well known. Parenchymal injuries in the lung cause air leakage that resolves with wound healing. We aimed to determine the effect of glutamine on the healing of lung injuries. Wistar albino female rats were randomized in three groups. One group (control, n = 7) received intraperitoneal injection of 0.9% sodium chloride (1.5 ml /day), while other group (GLN, n = 7) received glutamine (1.5 g/kg/day), beginning two days prior to the operation for total four days. After thoracotomy, a lung parenchymal lesion was made with a scalpel in the right upper lobe. Only thoracotomy was performed to sham group (n = 4). Air leakage was observed in the isolated lungs of control group, but not GLN and sham groups, at 5 cm H(2)O of positive airway pressure (p < 0.001). The threshold of positive airway pressure for air leakage was 4.85 +/- 0.37 and 19.42 +/- 4.54 cm H(2)O for control and GLN groups, respectively (p < 0.001). For measurement of collagen content in the healing parenchyma, digital images were processed to calculate the stained area percentage (SAP). SAP for immature collagen, a marker for wound healing, was 0.36 +/- 0.18% and 1.48 +/- 0.83% (p = 0.02) in control and GLN groups, respectively, but no significant difference was noted in SAP for mature collagen. The grade of inflammation was not significantly different between control and GLN groups. We conclude that glutamine enhances lung parenchymal healing by increasing immature collagen secretion.

This study reports the challenges faced by French military surgeons in the management of thoracic injury during the latest Afghanistan war. From January 2009 to April 2013, all of the civilian, French and Coalition casualties admitted to French NATO Combat Support Hospital situated on Kabul were prospectively recorded in the French Military Health Service Registry (OPEX(®)). Only penetrating and blunt thoracic trauma patients were retrospectively included. Eighty-nine casualties were included who were mainly civilian (61%) and men (94%) with a mean age of 27.9 years old. Surgeons dealt with polytraumas (78%), severe injuries (mean Injury Severity Score=39.2) and penetrating wounds (96%) due to explosion in 37%, gunshot in 53% and stabbing in 9%. Most of casualties were first observed or drained (n=56). In this non-operative group more than 40% of casualties needed further actions. In the operative group, Damage Control Thoracotomy (n=22) was performed to stop ongoing bleeding and air leakage and Emergency Department Thoracotomy (n=11) for agonal patient. Casualties suffered from hemothorax (60%), pneumothorax (39%), diaphragmatic (37%), lung (35%), heart or great vessels (20%) injuries. The main actions were diaphragmatic sutures (n=25), lung resections (wedge n=6, lobectomy n=4) and haemostasis (intercostal artery ligation n=3, heart injury repairs n=5, great vessels injury repairs n=5). Overall mortality was 11%. The rate of subsequent surgery was 34%. The analysis of the OPEX(®) registry reflects the thoracic surgical challenges of general (visceral) surgeons serving in combat environment during the latest Afghanistan War.

To investigate the value of preoperative barium contrast examination for the diagnosis and operative planning in gastric cancer. Clinical data of 229 gastric cancer patients were analyzed retrospectively. Lesions were divided into three parts: the cardiac, the body, and the antrum. The diagnostic accuracy of localization and the extent of tumor between gastroscopy alone and gastroscopy plus barium contrast were compared with the results of surgical findings. The diagnostic accuracy of localization and the extent of tumor for gastroscopy in the cardiac, the body and the antrum cancers were 100% and 78.4%, 94.6% and 86.5%, 98.1% and 84.6%, respectively, while for gastroscopy plus barium contrast were 100% and 84.8%, 100% and 91.9%, 99.0% and 90.4%, respectively. The diagnostic accuracy of both the localization and the extent of tumor were not significantly different between gastroscopy alone and gastroscopy plus barium contrast (P>0.05). Diagnostic accuracy of the length of esophagus infiltrated by cardiac cancer in gastroscopy was 60.6%, while in gastroscopy plus barium contrast was 90.9%, which was significantly different (P<0.05). Gastroscopy plus barium contrast was more accurate in predicting the possibility of thoracotomy in cardiac cancer infiltrating the lower esophagus. It is necessary to perform preoperative barium contrast examination in cardiac cancer patients, so as to identify whether the lower esophagus is infiltrated and to measure the length of lesion, which can provide evidences for making a decision of thoracotomy. For gastric body and antrum cancer, there is no indication for barium contrast examination if gastroscopy findings are satisfied.

This review was conducted to compare the contributions of chest X-ray (CXR) and computed tomography (CT) towards detecting intrathoracic damage in patients with penetrating war injuries to the chest and to determine whether identification of additional injuries by chest CT will have an impact on the choice of therapeutic interventions and clinical outcomes. We reviewed records of 449 patients (374 men, mean age 29.3 ± 14.8 years) who were admitted to our hospital with penetrating war injuries to the chest over a 7-year period. Collected data included mechanisms of injury, associated injuries, results of CXRs and chest CTs, methods of management, in-hospital stays, complications and mortalities. Immediate screening CXRs were obtained in all patients not requiring emergent thoracotomies, of which 91.4% showed positive signs of injury. Chest CTs were performed at the discretion of the physicians in 49.4% of patients, and CXR-positive findings were confirmed in all cases, while revealing additional injuries in 11% of patients. Chest CT findings led to additional closed chest drainage in 5.6% of patients but had no impact on treatment strategy in 94.4% of scanned patients. Follow-up CXRs showed new positive findings in 22 patients, leading to additional closed chest drainage in 3 patients and delayed open thoracotomies in 7 other patients. CXRs continue as the primary diagnostic modality in the assessment of patients with penetrating war injuries to the chest. Chest CTs can be omitted in most patients, thus reducing CT imaging case-load substantially, while most clinically significant chest injuries remain sufficiently recognized.

Despite the many recent advances in thoracic surgery, the management of patients with recurrent, nonmalignant tracheoesophageal fistulas remains problematic, controversial, and challenging. Between 1998 and 2008, we treated 8 patients with RTEF. Closure of the original tracheoesophageal fistula had been attempted once in 5 patients, twice in 2 patients, and 4 times in 1 patient, all in different institutions. Four cases necessitated right posterolateral thoracotomy and cervical exposure, 2 cases cervical and abdominal incision, and 1 case right posterolateral thoracotomy, with abdominal and cervical exposure. With the exception of the 2 patients whose excluded esophagus was used to substitute for the trachea membranous wall, the damaged tracheal segment was removed. In general, a pedicled mediastinal pleural flap was pulled into the neck to increase the safety of the tracheal anastomosis formed with the trachea, and (or) to separate the suture lines of the two organs. A single intervention was sufficient for all 8 patients: no reoperation was necessary, and there was no perioperative mortality. Transient reflux, abdominal distention, and dyspnea in response to forced physical exertion occurred in 1 case each. Only 1 patient subsequently takes medication regularly for reflux disease. Separation initiated from the tracheal bifurcation, a pedicled mediastinal pleural flap pulled into the neck, a tracheal anastomosis sewn onto the cricoid cartilage with avoidance of its posterolateral elbow, a shaped Dumon stent (Novatech, Plan de Grasse, France) with an individually fenestrated tracheostomy cannula, and endoscopy-assisted, transhiatal vagal-preserving esophageal exclusion all served as successful elements of our surgical procedures. 2010 The Society of Thoracic Surgeons.

Minimally invasive left thoracotomy (MILT) and off-pump implantation strategies have been anecdotally reported for implantation of the HeartWare ventricular assist device (HVAD). We analyzed our experience with off-pump MILT implantation techniques and compared early in-hospital outcomes with conventional on-pump sternotomy (CS) implantation strategy. Between January 2013 and February 2014, 51 patients underwent HVAD implantation and were included in this study. Thirty-three patients had CS, whereas 18 patients underwent off-pump MILT. To compare outcomes of these techniques, a multivariate analysis using propensity score modeling was performed after adjusting for age, INTERMACS, Kormos and Leitz-Miller (LM) scores. Mean age at implant was 57 (range 18 to 69) years, and overall in-hospital mortality was 8%. Univariate analysis revealed a statistically significant reduction in days on inotropes (p = 0.04), and a trend toward reduced intra-operative blood product administration (p = 0.08) in the MILT group. There was no difference in intensive-care-unit length of stay (p = 0.5), total length of stay (p = 0.76), post-operative blood product administration (p = 0.34) and total time on mechanical ventilation (p = 0.32). After adjusting for age, INTERMACS profile and Kormos and LM scores, no statistically significant differences were observed between the MILT and CS groups. An off-pump MILT implantation strategy can be utilized as a safe surgical approach for patients undergoing HVAD implantation. Further large collaborative studies are needed to identify advantages of the MILT approach. Published by Elsevier Inc.

As ventricular-assist devices (VADs) are increasingly employed in heart failure management, a leading cause of mortality, new literature is consistently published on less-invasive implantation techniques. Although early perioperative outcomes have been shown to be favorable with minimally invasive left thoracotomy (LT) approaches compared with conventional sternotomy (CS), studies comparing long-term outcomes are lacking. We set out to evaluate long-term follow up between LT and CS approach. In a single center, retrospective review, data on patients with similar demographic profiles were collected. HeartWare (HVAD) implantation was performed by either CS or LT. Analysis was performed on perioperative adverse outcomes, and 6 month postoperative adverse events. Primary objectives of the study included comparative outcomes of morbidity and mortality between both groups at 180 days postimplantation. Eighty-one (n = 81) bridge to transplant (BTT) patients underwent CS or LT HVAD implantation. Perioperative transfusion (p = 0.04) favored the LT cohort compared with CS, with a median of 6 units and 8 units transfused for each group, respectively. No survival difference was observed between both groups at 6 months postimplantation (p = 0.52). Clinical outcomes at an average of 6 month follow up showed no difference in adverse events, including common postoperative VAD complications such as infection and right heart failure. Miniaturization of LVAD size and improvement in technology has allowed expansion of interest in alternative surgical approaches for HVAD implantation. For BTT patients, no difference in early outcome was observed 6 months after implantation using a left LT versus CS technique.

We report an initial experience with the new and potentially advantageous technique of videothoracoscopy in the treatment of pneumothorax. A series of 18 consecutive patients (14 male, 4 female) presenting with spontaneous pneumothorax over a 4-month period underwent surgical treatment by this method. The indication for surgery was recurrent pneumothorax in nine patients and persistent air leak in the remainder (median duration 15 days, range 5-28 days). Stapled apical bullectomy with apical parietal pleurectomy was performed in 14 patients, bullectomy alone was performed in one patient and pleurectomy alone in three patients. Additional talc pleurodesis was carried out in three of these patients. Median duration of operation was 53.5 min (range 35-120 min). The median postoperative drainage was 300 ml in 24 h (range 50-580 ml). The median duration of intercostal drainage was 48 h (range 24-384 h) and of postoperative hospital stay 4 days (range 3-18 days). The mean postoperative analgesic requirement was 1.3 mg morphine/h. Three complications required reoperation. In two patients a large air leak persisted after operation; one proceeded to thoracotomy for suturing of the air leak and in the other this was accomplished by videothoracoscopy. A further patient re-presented at 2 weeks with recurrent pneumothorax which was treated at thoracotomy. At a median follow-up of 68.5 days (range 10-124 days) this is the only recurrence. These complications were caused by errors in surgical technique early in our series. This initial experience of videothoracoscopic pleurectomy suggests it is an effective, well-tolerated treatment of spontaneous pneumothorax. PMID:8379623

Background Pediatric chest injuries were infrequent in our practice, but the outbreak of the Syrian crisis resulted in an increase in number and a change in the pattern of thoracic trauma incidents. We compared our experience of pediatric chest injuries before and during the crisis. Methods We reviewed the records of 256 children aged 12.8 ± 5 years who were admitted to our hospital with the diagnosis of chest trauma over a 12-year period. Collected data included mechanism of injury, associated injuries, method of management, length of hospital stay, complications, and mortality. Results The incidence of pediatric chest injuries increased significantly following the outbreak of the crisis, and penetrating injuries prevailed, mainly due to shrapnel, bullets, and stab wounds. Forty percent of patients with blunt injuries and 20% of those with penetrating injuries were managed conservatively, whereas urgent thoracotomies were indicated in 10%, mostly in patients with penetrating injuries. Associated injuries were more frequent in patients with blunt injuries and resulted in a longer hospital stay and an increased mortality rate. The overall mortality rate was 7.8% and it was higher in children younger than 7 years of age and in patients who had been subjected to blunt injuries. Conclusions There has been a recent substantial upsurge in the incidence of pediatric thoracic trauma, with a predominance of penetrating injuries. Most patients could be managed nonoperatively, but a small subset required an open thoracotomy. The presence of associated injuries constitutes the main determinant of prognosis in this group of patients.

Transthoracic device closure (TTDC) and surgical repair with right infra-axillary thoracotomy (SRRIAT) are two main alternative minimally invasive approaches for restrictive perimembranous ventricular septal defect (VSD); however, few studies have compared them with each other in terms of effectiveness and cost. Patients with perimembranous VSD undergoing TTDC or SRRIAT from January 2012 to July 2013 were reviewed in a comparative investigation between the two procedures. Success from the procedures was achieved in 30 TTDC (30/33, 91%) and 96 SRRIAT patients (100%). Operation duration in the TTDC group was significantly shorter than that of the SRRIAT group (115.8 ± 43.8 vs 175.6 ± 41.3 min, P < 0.01). The total perioperative drainage, use of red blood cells, mechanical ventilation time, stay in the intensive care unit and hospital stay for the TTDC group were significantly less than those in the SRRIAT group. No deaths or complete atrioventricular block occurred in either group. One SRRIAT patient accepted a second surgery for residual shunt. TTDC costs slightly more than SRRIAT (40270.6 ± 2741.3 renmingbi [RMB] vs 32964.5 ± 8221.6 RMB, P < 0.01). Both TTDC and SRRIAT showed excellent outcomes and cosmetic appearance for suitable VSD candidates. Although its costs were higher, TTDC had the advantages over SRRIAT of a short operation duration and intensive care unit stay and fewer days in the hospital. © The Author 2014.

Recent evidence points to an association between experimental pain measures obtained preoperatively and acute postoperative pain (POP). We hypothesized that pain temporal summation (TS) might be an additional predictor for POP insofar as it represents the neuroplastic changes that occur in the central nervous system following surgery. Therefore, a wide range of psychophysical tests (TS to heat and mechanical repetitive stimuli, pain threshold, and suprathreshold pain estimation) and personality tests (pain catastrophizing and anxiety levels) were administered prior to thoracotomy in 84 patients. POP ratings were evaluated on the 2nd and 5th days after surgery at rest (spontaneous pain) and in response to activity (provoked pain). Linear regression models revealed that among all assessed variables, enhanced TS and higher pain scores for mechanical stimulation were significantly associated with greater provoked POP intensity (overall r2 = 0.225, P = .008). Patients who did not demonstrate TS to both modalities reported lower scores of provoked POP as compared with patients who demonstrated TS in response to at least 1 modality (F = 4.59 P = .013). Despite the moderate association between pain catastrophizing and rest POP, none of the variables predicted the spontaneous POP intensity. These findings suggest that individual susceptibility toward a greater summation response may characterize patients who are potentially vulnerable to augmented POP. This study proposed the role of pain temporal summation assessed preoperatively as a significant psychophysical predictor for acute postoperative pain intensity. The individual profile of enhanced pain summation is associated with the greater likelihood of higher postoperative pain scores.

Is VATS lobectomy standard of care for operable non-small cell lung cancer?

PubMed

Vannucci, Fernando; Gonzalez-Rivas, Diego

2016-10-01

Video-Assisted Thoracic Surgery (VATS) for treatment of lung cancer is being increasingly applied worldwide in the last few years. Since its introduction, many publications have been providing strong evidences that this minimally invasive approach is feasible, safe and oncologically efficient; offering to patients several advantages over traditional open thoracotomy, particularly for early-stage disease (I and II). The application of VATS for locally advanced disease treatment has also been largely described, but probably requires a further level of experience, which is more likely to be found in reference centers, with skilled experts. Although a large multi-institutional prospective randomized-controlled trial is the best way to confirm the superiority of one technique over another, such study comparing VATS versus open lobectomy for lung cancer is unlikely to ever come out. And in this scenario, retrospective data remains as the most reliable source of scientific information. Based on a literature review, the main objective of this article is to discuss to what extent VATS lobectomy can be considered the gold standard in the surgical treatment of lung cancer, taking into account the most important comparison aspects between the minimally invasive approach and open thoracotomy technique. This review addresses questions regarding lymph node dissection, oncologic efficacy, extended resections beyond standard lobectomy, post-operative complications/pain/quality of life, survival rates and the present limits of indication (and contraindication) for VATS, in order to define the real role of this technique on the surgical treatment of lung cancer in a minimally invasive, but safe and effective manner.

This study was designed to compare the long-term clinical outcomes and costs between video-assisted thoracic surgery (VATS) and posterolateral thoracotomy (PT) in neonates and infants. This study enrolled 302 patients with isolated patent ductus arteriosus (PDA) from January 2002 to 2007 and followed them up until April 2010. A total of 134 patients underwent total VATS (VATS group), and 168 underwent PDA closure through PT (PT group). The two groups were compared according to clinical outcomes and costs. The demographics and preoperative clinical characteristics of the patients were similar in the two groups. No cardiac deaths occurred, and the closure rate was 100% successful in both groups. The operating, recovery, and pleural fluid drainage times were significantly shorter in the VATS group than in the PT group. Statistically significant differences in length of incision, postoperative temperature, and acute procedure-related complications were observed between the two groups. The cost was $1,150.3 ± $221.2 for the VATS group and $2415.8 ± $345.2 for the PT group (P < 0.05). No cardiac deaths or newly occurring arrhythmias were detected in either group during the follow-up period. Statistically significant differences in the rate of residual shunt and scoliosis were observed between the two groups. The left ventricular end-diastolic diameter and the pulmonary artery diameter could be restored to normal in the VATS group but not in the PT group. The study confirmed that VATS offers a minimally traumatic, safe, and effective technique for PDA interruption in neonates and infants.

In the absence of thromboprophylaxis, coronary artery bypass graft surgery (CABG), intrathoracic surgery (thoracotomy or video-assisted thoracoscopy), abdominal aortic surgery and infrainguinal vascular surgery are high-risk surgeries for the development of venous thromboembolic events (VTE). The incidence of VTE following surgery of the intrathoracic aorta, carotid endarterectomy or mediastinoscopy is unknown. Data from the litterature are lacking to draw evidence-based recommandations for venous thromboprophylaxis after these three types of surgeries, and the following guidelines are but experts'opinions (Grade D recommendations). Thromboprophylaxis is recommended after CABG (Grade D), with either subcutaneous (SC) low molecular weight heparin (LMWH) or SC or intravenous (i.v.) unfractioned heparin (UH) (PTT target = 1.1-1.5 time control value) (both grade D). This may be combined with the use of intermittent pneumatic compression device (Grade B). After valve surgery. The anticoagulation recommended to prevent valve thrombosis is sufficient in order to prevent VTE. We recommend thromboprophylaxis with either LMWH or low dose UH to prevent VTE after aortic or lower limbs infrainguinal vascular surgery (both grade B and D). Vitamine K antagonists (VKA) are not recommended in this indication (Grade D). We recommend thromprophylaxis following intrathoracic surgery via thoracotomy or videoassisted thoracoscopy (grade C). Either subcutaneous LMWH or subcutaneous or i.v. low dose UH may be used (Grade C). Efficacy of intermittent pneumatic compression device has been demonstrated in a study (grade C). VKA are not recommended (grade D). No further recommendation regarding the duration of thromboprophylaxis after these three types of surgeries can be made.

To elucidate the mechanism of arrhythmia in healed myocardial infarction (HMI), the changes of action potential duration (APD), transient outward potassium current (Ito), delayed rectifier potassium current (IK) and inward rectifier potassium current (IK1) of left ventricular myocytes in non-infarcted zone of HMI were investigated. Rabbits were randomly assigned into two groups: HMI group, in which animals were subjected to thoracotomy and ligation of the circumflex coronary and sham-operated group, in which rabbits underwent thoracotomy but no conorary ligation. 3 months after the operation, the whole myocyte patch clamp technique was used to record APD, Ito, IK, and IK1 of ventricular myocytes in non-infarcted zone. Our results showed that the membrane capacitance was larger in HMI group than in sham-operated group. Action potential duration was significantly lengthened in HMI group and early afterdepolarization (EAD) appeared in HMI group. The densities of Ito, I(K, tail), and IK1 were reduced significantly in HMI group, from 6.72 +/- 0.42 pA/pF, 1.54 +/- 0.13 pA/pF and 25.6 +/- 2.6 pA/pF in sham-operated group to 4.03 +/- 0.33 pA/pF, 1.14 +/- 0.11 pA/pF and 17.6 +/- 2.3 pA/pF, respectively. It is concluded that the reduced densities of Ito, I(K, tail) and IK1 in ventricular myocytes of non-infarcted zone in HMI were responsible for the prolongation of APD and the presentation of EAD which played important roles in the development of malignant arrhythmia in HMI.

Endometriosis of the lung: report of a case and literature review

PubMed Central

2013-01-01

This paper reports a case of endometriosis of the lung in a 29-year-old woman with long-term periodic catamenial hemoptysis. A chest computed tomography image obtained during menstruation revealed a radiographic opaque lesion in the lingular segment of the left superior lobe. During bronchoscopy, bleeding in the mucosa of the distal bronchus of the lingular segment of the left superior lobe was observed. Histopathology subsequent to an exploratory thoracotomy confirmed the diagnosis of endometriosis of the left lung. The 2-year follow-up after lingular lobectomy of the left superior lobe showed no recurrence or complications. PMID:23634803

Lower esophageal fistula is a rare complication after upper digestive tract surgery, but it is associated with high morbi-mortality. There is no consensus on therapeutic care, however when reoperation is necessary, a pedicled inter-costal flap from the thoracotomy can be easily harvested to patch a large defect or buttress a direct suture, saving -digestive reconstruction. This technique should be mastered by thoracic and general surgeons. We present here two cases of lower esophagus fistulas cured thanks to this intercostal flap, in which we avoided fistula recurrence with maintenance of digestive continuity.

The authors present the case of a 38-year-old female who presented with an ingested oesophageal foreign body (lamb bone) following consumption of a casserole. The bone was initially not seen on plain x-ray but CT imaging revealed a 21×20 mm pyramid shaped bone distending the proximal oesophageal mucosa and lodged only 2 mm from the aortic arch. Cardiothoracic surgery services were available on standby to perform an emergency thoracotomy in the event of any haemorrhage. However, the bone was removed successfully with rigid oesophagoscopy and the patient made a full recovery. PMID:22689831

Spontaneous haemothorax is a subcategory of haemothorax that occurs in the absence of trauma or other causes. It is a rare emergency that can progress rapidly with massive blood loss leading to haemorrhagic shock and death. We describe a patient with massive spontaneous haemothorax caused by the disruption of an oesophageal artery from the middle segment of descending thoracic aorta. We sutured the bleeding artery in an emergency thoracotomy after the failure of interventional procedure. © The Author 2017.

Various etiologies of spontaneous hemothorax have been reported, though the cause remains unidentified in some patients despite an exploratory thoracotomy. We report on an 89-year-old man with spontaneous hemothorax resolved by partial resection of the lung using complete video-assisted thoracoscopic surgery. The histopathologic findings revealed a ruptured micro-venous hemangioma located just below the bleeding visceral pleura. To the best of our knowledge, this is the first report of spontaneous hemothorax caused by a pulmonary micro-venous hemangioma. Copyright © 2015 The Society of Thoracic Surgeons.

The overall advantages of thoracoscopy over thoracotomy in terms of patient recovery have been fairly well established. The use of robotics, however, is a newer and less proven modality in the realm of thoracic surgery. Robotics offers distinct advantages and disadvantages in comparison with video-assisted thoracoscopic surgery. Robotic technology is now used for a variety of complex cardiac, urologic, and gynecologic procedures including mitral valve repair and microsurgical treatment of male infertility. This article addresses the potential benefits and limitations of using the robotic platform for the performance of a variety of thoracic operations. Copyright © 2014 Elsevier Inc.

Objective: To analyze the clinical features of one case of spontaneous hemothorax caused by primary pleural chondrosarcoma and therefore to improve the understanding of this disease. Methods: The clinical features of a case with primary pleural chondrosarcoma were analyzed retrospectively and the related literatures were reviewed.The literature review was carried out with "primary pleural, chondrosarcoma" in Chinese and English respectively, as the search terms in Wanfang Data, CNKI and PubMed database from January 1980 to October 2015. A total of 6 articales, 1 in Chinese and 5 in English, were reviewed. Results: A 29 year-old male patient was admitted to the hospital because of fever, chest tightness, shortness of breath for 20 days. CT scan of the chest showed a mass near the right posterior fourth rib and right pleural effusion.Routine examination of the pleural effusion confirmed the presence of hemothorax. Thoracotomy was performed and revealed hemothorax in the right thorax, and a mass near the pleural apex. The tumor was removed by surgery and pleural decortication was also performed. Pathology study confirmed the diagnosis of high-differentiated chondrosarcoma. The patient was followed and there was no recurrence until now. A total of 6 case reports were retrieved from Wanfang Data, CNKI and PubMed. Five cases had complete data, including 2 males and 3 females(age from 28 to70), and another (a 78-year old male) without adequate data. Conclusions: Primary pleural chondrosarcoma is a rare disease, and hemothorax as the first manifestation is even rare. It is easily to be misdiagnosed due to nonspecific clinical symptoms.The final diagnosis depends ultimately on pathological biopsy. Thoracotomy is the most effective method for treatment of primary pleural chondrosarcoma.

American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) grades IV and V complex hepatic injuries are highly lethal. Our objectives were to review experience and identify predictors of outcome and to evaluate the role of angioembolization in decreasing mortality. This was a retrospective 8-year study of all patients sustaining AAST-OIS grades IV and V hepatic injuries managed operatively. Statistical analysis was performed using univariate and multivariate logistic regression. The main outcome measure was survival. The study included 103 patients, with a mean Revised Trauma Score of 5.61 +/- 2.55 and a mean Injury Severity Score of 33 +/- 9.5. Mechanism of injury was penetrating in 80 (79%) and blunt in 23 (21%). Emergency department thoracotomy was performed in 21 (25%). AAST grade IV injuries occurred in 51 (47%) and grade V injuries occurred in 52 (53%). Mean estimated blood loss was 9,414 mL. Overall survival was 43%. Adjusted overall survival rate after emergency department thoracotomy patients were excluded was 58%. Results stratified to AAST-OIS injury grade were as follows: grade IV, 32 of 51 (63%); grade V, 12 of 52 (23%); grade IV versus grade V (p < 0.001) odds ratio, 2.06; 95% confidence interval, 2.72 (1.40-3.04). Logistic regression analysis identified as independent predictors of outcome Revised Trauma Score (adjusted p < 0.0002), angioembolization (adjusted p < 0.0177), direct approach to hepatic veins (adjusted p < 0.0096), and packing (adjusted p < 0.0013). Improvements in mortality can be achieved with an appropriate operative approach. Angioembolization as an adjunct procedure decreases mortality in AAST-OIS grades IV and V hepatic injuries.

Bronchopulmonary malformations (BPM) are rare conditions, which typically arise below the carina and can result in significant morbidity (infection and/or hemorrhage) and mortality (respiratory failure). All children with BPM surgically treated from 2001-2014 at a tertiary care children's hospital were identified. Patient demographics, surgical indications, procedure type, estimated blood loss, pathology, perioperative complications, length of stay, and outcomes were analyzed. A total of 41 BPM patients underwent surgery with 98% overall survival (one abdominal BPM expired) but 100% for thoracic lesions. Resections were performed thoracoscopically (37%), thoracoscopy converted to open (22%), and via thoracotomy (37%). Poor visualization (67%) or inability to tolerate single lung ventilation (33%) led to conversions. No conversions resulted from hemorrhage or received blood transfusions. Patients with prenatally diagnosed BPM were more likely to undergo thoracoscopic surgery (odds ratio [OR], 18.2) versus nonprenatally diagnosed, P = 0.002. Open/converted patients had longer chest tube days (6.2) versus thoracoscopic (2.9), P = 0.048. Additionally, respiratory distress was a more common indication in patients aged <4 mo (OR, 28.0) versus ≥4 mo and <6 kg (OR, 40.5) versus ≥6 kg, P < 0.001. Open resections were more common in patients aged <4 mo (OR, 26.3) versus ≥4 mo, P = 0.002. Operative time was shorter and estimated blood loss (mL/kg) was greater for <6 versus ≥6 kg, P < 0.05. BPM resections have high overall survival. Chest tube days are shorter among thoracoscopic patients, but conversion to thoracotomy can avoid hemorrhage and need for transfusion. Size and respiratory distress limit use of thoracoscopy in young infants with BPM. Copyright © 2015 Elsevier Inc. All rights reserved.

Minimally invasive surgery of pulmonary nodules allows suboptimal palpation of the lung compared to open thoracotomy. The objective of this study was to assess endoscopic pleural dye marking using radial endobronchial ultrasound (r-EBUS) and virtual bronchoscopy to localize small peripheral lung nodules immediately before minimally invasive resection. The endoscopic procedure was performed without fluoroscopy, under general anesthesia in the operating room immediately before minimally invasive surgery. Then, 1 mL of methylene blue (0.5%) was instilled into the guide sheath, wedged in the subpleural space. Wedge resection or segmentectomy were guided by visualization of the dye on the pleural surface. Contribution of dye marking to the surgical procedure was rated by the surgeon. Twenty-five nodules, including 6 ground glass opacities, were resected in 22 patients by video-assisted thoracoscopic wedge resection (n = 11) or robotic-assisted thoracoscopic surgery (10 segmentectomies and 1 wedge resection). The median greatest diameter of nodules was 8 mm. No conversion to open thoracotomy was needed. The endoscopic procedure added an average 10 min to surgical resection. The dye was visible on the pleural surface in 24 cases. Histological diagnosis and free margin resection were obtained in all cases. Median skin-to-skin operating time was 90 min for robotic segmentectomy and 40 min for video-assisted wedge resection. The same operative precision was considered impossible by the surgeon without dye marking in 21 cases. Dye marking using r-EBUS and virtual bronchoscopy can be easily and safely performed to localize small pulmonary nodules immediately before minimally invasive resection. © 2018 S. Karger AG, Basel.

Gastrobronchial fistula (GBF) is a serious complication following bariatric surgery, whose treatment by thoracotomy and/or laparotomy involves a high morbidity rate. We present the outcomes of endoscopic management for GBF as a helpful technique for its healing process. This is a multicenter retrospective study of 15 patients who underwent gastric bypass (n = 10) and sleeve gastrectomy (n = 5) and presented GBF postoperatively (mean of 6.7 months). Ten patients developed lung abscess and were treated by antibiotic therapy (n = 10) and thoracotomy (n = 3). Abdominal reoperation was performed in nine patients for abscess drainage (n = 9) and/or ring removal (n = 4) and/or nutritional access (n = 6). The source of the GBF was at the angle of His (n = 14). Furthermore, 14 patients presented a narrowing of the gastric pouch treated by 20 or 30 mm aggressive balloon dilation (n = 11), stricturotomy or septoplasty (n = 10) and/or stent (n = 7). Fibrin glue was used in one patient. We performed, on average, 4.5 endoscopic sessions per patient. Endotherapy led to a 93.3% (14 out of 15) success rate in GBF closure with an average healing time of 4.4 months (range, 1-10 months), being shorter in the stent group (2.5 × 9.5 months). There was no recurrence during the average 27.3-month follow-up. A patient persisted with GBF, despite the fibrin glue application, and decided to discontinue it. GBF is a highly morbid complication, which usually arises late in the postoperative period. Endotherapy through different strategies is a highly effective therapeutic option and should be implemented early in order to shorten leakage healing time.

Historically, patients with penetrating cardiac injuries have enjoyed the best survival after emergency department thoracotomy (EDT), but further examination of these series reveals a preponderance of cardiac stab wound (SW) survivors with only sporadic cardiac gunshot wound (GSW) survivors. Our primary study objective was to determine which patients requiring EDT for penetrating cardiac or great vessel (CGV) injury are salvageable. All patients who underwent EDT for penetrating CGV injuries in two urban, level I trauma centers during 2000 to 2007 were retrospectively reviewed. Demographics, injury (mechanism, anatomic injury), prehospital care, and physiology (signs of life [SOL], vital signs, and cardiac rhythm) were analyzed with respect to hospital survival. The study population (n = 283) comprised young (mean age, 27.1 years +/- 10.1 years) men (96.1%) injured by gunshot (GSW, 88.3%) or SWs (11.7%). Patients were compared by injury mechanism and number of CGV wounds with respect to survival (SW, 24.2%; GSW, 2.8%; p < 0.001; single, 9.5%; multiple, 1.4%; p = 0.003). Three predictors-injury mechanism, ED SOL, and number of CGV wounds-were then analyzed alone and in combination with respect to hospital survival. Only one patient (0.8%) with multiple CGV GSW survived EDT. When the cumulative impact of penetrating injury mechanism, ED SOL, and number of CGV wounds was analyzed together, we established that those sustaining multiple CGV GSWs (regardless of ED SOL) were nearly unsalvageable. These results indicate that when multiple CGV GSWs are encountered after EDT, further resuscitative efforts may be terminated without limiting the opportunity for survival.

Electrochemical treatment of lung cancer

A pilot study of electrochemical treatment (ECT) as a therapy for 386 patients with nonsmall cell lung cancer was undertaken. There were 103 stage 2 cases, 89 stage 3a cases, 122 stage 3b cases, and 72 stage 4 cases. Two ECT methods were used. For peripherally located lung cancer, platinum electrodes were inserted transcutaneously into the tumor under x-ray or CT guidance. For central type lung cancer or for those inoperable during thoracotomy, electrodes were inserted intraoperatively directly into the cancer. Voltage was 6--8 V, current was 40--100 mA, and electric charge was 100 coulombs per cm of tumor diameter.more » The number of electrodes was determined from the size of cancer mass, because the diameter of effective area around each electrode is approximately 3 cm. The short-term (6 months after ECT) results of the 386 lung cancer cases were: complete response (CR), 25.6% (99/386); partial response (PR), 46.4% (179/386); no change (NC), 15.3% (59/386); and progressive disease (PD), 12.7% (49/386). The total effective rate (CR + PR) was 72% (278/386). The 1, 3, and 5 year overall survival rates were 86.3% (333/386), 58.8% (227/386), and 29.5% (114/386), respectively. The main complication was traumatic pneumothorax, with an incidence rate of 14.8% (57/386). These clinical results show that ECT is simple, safe, effective, and minimally traumatic. ECT provides an alternative method for treating lung cancers that are conventionally inoperable, that are not responsive to chemotherapy or radiotherapy, or that cannot be resected after thoracotomy. Long-term survival rates suggest that ECT warrants further investigation.« less

Sudden generalized lung atelectasis during thoracotomy following thoracic lavage in 3 dogs.

To describe sudden onset of generalized pulmonary atelectasis following thoracic lavage in 3 dogs. Thoracic lavage was performed following ligation of a patent ductus arteriosus in case 1, prior to closure of a large traumatic full thickness wound in the chest wall in case 2, and during investigation of an idiopathic spontaneous pneumothorax in case 3. In each case anesthesia and surgery were uneventful until thoracic lavage was performed, after which sudden generalized pulmonary atelectasis was observed. The atelectasis was visualized and was associated with oxyhemoglobin desaturation, decreased end-tidal carbon dioxide partial pressure (ETCO(2)), and a marked increase in the peak inspiratory pressure (PIP) required to achieve visible lung inflation. Occlusion of the endotracheal tube and cervical trachea was directly eliminated as the cause of atelectasis in cases 1 and 2, and indirectly eliminated in case 3. Improvement in pulmonary function occurred in all cases in response to increased PIP ± positive end expiratory pressure (PEEP). Generalized atelectasis should be considered a possible complication of thoracic lavage performed during thoracotomy. In the cases presented here, it is suspected that pre-existing reduction in lung volume (due to inadequate ventilation, surgical compression, absorption atelectasis) was exacerbated by the addition of the lavage fluid to the thoracic cavity. This pre-existing lung collapse is believed to have resulted in reduction of lung volume and that further reduction below the critical closing volume occurred following instillation of saline into the thorax resulting in the subsequent development of generalized atelectasis. The performance of regular arterial blood gas analyses and different ventilation protocols may have prevented the marked atelectasis that was observed in these cases. © Veterinary Emergency and Critical Care Society 2012.

Surgical and medical procedures, mainly those associated with nerve injuries, may lead to chronic persistent pain. Currently, one cannot predict which patients undergoing such procedures are 'at risk' to develop chronic pain. We hypothesized that the endogenous analgesia system is key to determining the pattern of handling noxious events, and therefore testing diffuse noxious inhibitory control (DNIC) will predict susceptibility to develop chronic post-thoracotomy pain (CPTP). Pre-operative psychophysical tests, including DNIC assessment (pain reduction during exposure to another noxious stimulus at remote body area), were conducted in 62 patients, who were followed 29.0+/-16.9 weeks after thoracotomy. Logistic regression revealed that pre-operatively assessed DNIC efficiency and acute post-operative pain intensity were two independent predictors for CPTP. Efficient DNIC predicted lower risk of CPTP, with OR 0.52 (0.33-0.77 95% CI, p=0.0024), i.e., a 10-point numerical pain scale (NPS) reduction halves the chance to develop chronic pain. Higher acute pain intensity indicated OR of 1.80 (1.28-2.77, p=0.0024) predicting nearly a double chance to develop chronic pain for each 10-point increase. The other psychophysical measures, pain thresholds and supra-threshold pain magnitudes, did not predict CPTP. For prediction of acute post-operative pain intensity, DNIC efficiency was not found significant. Effectiveness of the endogenous analgesia system obtained at a pain-free state, therefore, seems to reflect the individual's ability to tackle noxious events, identifying patients 'at risk' to develop post-intervention chronic pain. Applying this diagnostic approach before procedures that might generate pain may allow individually tailored pain prevention and management, which may substantially reduce suffering.

Background Right anterior mini-thoracotomy (MIAVR) is a promising technique for aortic valve replacement. We aimed at comparing its outcomes with those obtained in a propensity-matched group of patients undergoing sternotomy at our two high-volume centers. Methods Main clinical and operative data of patients undergoing aortic valve replacement between January 2010 and May 2016 were retrospectively collected. A total of 678 patients were treated with a standard full sternotomy approach, while MIAVR was performed in 502. Propensity score matching identified 363 patients per each group. Results In-hospital mortality was not significantly different between the propensity-matched groups (1.7% in MIAVR patients vs. 2.2% in conventional sternotomy patients; P=0.79). No significant difference in the incidence of major post-operative complications was observed. Post-operative ventilation times (median 7, range 5–12 hours in MIAVR patients vs. median 7, range 5–12 in conventional sternotomy patients; P=0.72) were not significantly different between the two groups. Cardiopulmonary bypass time (61.0±21.0 vs. 65.9±24.7 min in conventional sternotomy group; P<0.01) and aortic cross-clamping time (48.3±16.7 vs. 53.2±19.6 min in full sternotomy group; P<0.01) were shorter in MIAVR group. EuroSCORE (OR 1.52, 95% CI, 1.12–2.06; P<0.01) was found to be the only independent predictor of intra-hospital mortality in the whole propensity-matched population. Conclusions Our experience shows that mini-access isolated aortic valve surgery is a reproducible, safe and effective procedure with similar outcomes and no longer operative times compared to conventional sternotomy.

To compare the differences of injuries and recovery between video-assisted thoracoscopic surgery (VATS) and mini-thoracotomy (MT) in patients with clinical early stage non-small cell lung cancer (NSCLC) after lobectomy. From March 2004 to December 2006, 47 consecutive patients with early stage NSCLC with a diameter of tumor less than 6 cm were recruited and randomized to VATS group and MT group. Incision length, duration of operation and intraoperative blood loss were recorded. Postoperative pain was assessed using a visual analogue scale before operation and daily for the first 7 days after operation. The serum levels of interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured by cytometric bead array before operation and at 4, 24, and 48 h after operation. Karnofsky performance status (KPS) was assessed before operation and daily for the first 7 days after operation. Incision length was (6.0 +/- 0. 9) cm in the VATS group and (12.5 +/- 1.5) cm in the MT group. There was no significant difference in duration of operation and intraoperative blood loss between the VATS group and the MT group. Postoperative pain was significantly less in the VATS group in the 5th to 7th day postoperatively (P < 0.05). There was no significant difference of serum concentrations of IL-6 and IL-10 between the VATS group and the MT group at 4, 24, and 48 h after operation. KPS score was significantly higher in the VATS group on 2nd to 7th day postoperatively (P < 0.05). Compared with MT, VATS for lobectomy has less postoperative pain, faster recovery, but can't reduce postoperative release of cytokines.

Pancreaticoduodenectomy (Whipple's procedure) is a formidable procedure when undertaken for severe pancreaticoduodenal injury. The purposes of this study were to review our experience with this procedure for trauma; to classify injury grades for both pancreatic and duodenal injuries in patients undergoing pancreaticoduodenectomy according to the American Association for the Surgery of Trauma-Organ Injury Scale for pancreatic and duodenal injury; and to validate existing indications for performance of this procedure. We performed a retrospective 126-month study (May 1992 to December 2002) of all patients admitted with proven complex pancreaticoduodenal injuries requiring pancreaticoduodenectomy. Eighteen patients were included; mean age was 32 +/- 12 years (SD), mean Revised Trauma Score was 6.84 +/- 2.13 (SD), and mean Injury Severity Score was 27 +/- 8 (SD). There were 17 penetrating injuries (94%) and 1 blunt injury (6%). One of 18 patients had an emergency department thoracotomy and died (100% mortality); 5 of the remaining 17 patients required operating room thoracotomies, and only 1 survived (80% mortality). There was 1 AAST-OIS pancreas grade IV injury, and there were 17 pancreas grade V injuries and 18 AAST-OIS duodenum grade V injuries. Indications for pancreaticoduodenectomy were: massive uncontrollable retropancreatic hemorrhage, 13 patients (72%); massive unreconstructable injury to the head of the pancreas/main pancreatic duct and intrapancreatic portion/distal common bile duct, 18 patients (100%); and massive unreconstructable injury, 18 patients (100%). Mean estimated blood loss was 6,888 +/- 7,866 mL, and overall survival was 67% (12 of 18 patients). Complex pancreaticoduodenal injuries requiring pancreaticoduodenectomy (Whipple's procedure) are uncommon but highly lethal; virtually all are classified as AAST-OIS grade V for both pancreas and duodenum. Current indications for performance of pancreaticoduodenectomy are valid and should be strictly applied during procedure selection.

Measuring patient-reported outcomes (PROs) has become increasingly important for assessing quality of care and guiding patient management. However, PROs have yet to be integrated with traditional clinical outcomes (such as length of hospital stay), to evaluate perioperative care. This study aimed to use longitudinal PRO assessments to define the postoperative symptom recovery trajectory in patients undergoing thoracic surgery for lung cancer. Newly diagnosed patients (N = 60) with stage I or II non-small cell lung cancer who underwent either standard open thoracotomy or video-assisted thoracoscopic surgery lobectomy reported multiple symptoms from before surgery to 3 months after surgery, using the MD Anderson Symptom Inventory. We conducted Kaplan-Meier analyses to determine when symptoms returned to presurgical levels and to mild-severity levels during recovery. The most-severe postoperative symptoms were fatigue, pain, shortness of breath, disturbed sleep, and drowsiness. The median time to return to mild symptom severity for these 5 symptoms was shorter than the time to return to baseline severity, with fatigue taking longer. Recovery from pain occurred more quickly for patients who underwent lobectomy versus thoracotomy (8 vs 18 days, respectively; P = .022). Patients who had poor preoperative performance status or comorbidities reported higher postoperative pain (all P < .05). Assessing symptoms from the patient's perspective throughout the postoperative recovery period is an effective strategy for evaluating perioperative care. This study demonstrates that the MD Anderson Symptom Inventory is a sensitive tool for detecting symptomatic recovery, with an expected relationship among surgery type, preoperative performance status, and comorbid conditions.

Intraoperative bleeding control by uniportal video-assisted thoracoscopic surgery†.

Owing to advances in video-assisted thoracic surgery (VATS), the majority of pulmonary resections can currently be performed by VATS in a safe manner with a low level of morbidity and mortality. The majority of the complications that occur during VATS can be minimized with correct preoperative planning of the case as well as careful pulmonary dissection. Coordination of the whole surgical team is essential when confronting an emergency such as major bleeding. This is particularly important during the VATS learning curve, where the occurrence of intraoperative complications, particularly significant bleeding, usually ends in a conversion to open surgery. However, conversion should not be considered as a failure of the VATS approach, but as a resource to maintain the patient's safety. The correct assessment of any bleeding is of paramount importance during major thoracoscopic procedures. Inadequate management of the source of bleeding may result in major vessel injury and massive bleeding. If bleeding occurs, a sponge stick should be readily available to apply pressure immediately to control the haemorrhage. It is always important to remain calm and not to panic. With the bleeding temporarily controlled, a decision must be made promptly as to whether a thoracotomy is needed or if the bleeding can be solved through the VATS approach. This will depend primarily on the surgeon's experience. The operative vision provided with high-definition cameras, specially designed or adapted instruments and the new sealants are factors that facilitate the surgeon's control. After experience has been acquired with conventional or uniportal VATS, the rate of complications diminishes and the majority of bleeding events are controlled without the need for conversion to thoracotomy. © The Author 2015.

Pulmonary blastoma is an uncommon lung malignancy, usually presenting itself as a large chest mass causing pain, hemoptysis, cough and dyspnea; however, it is asymptomatic in up to 40% of patients. We present the case and suggestive images of a 37-year-old non-smoking lady with a monophasic pulmonary blastoma located in the lower lobe of the left lung who underwent a left posterolateral thoracotomy with lower lobectomy, hilar and mediastinal node dissection, followed by chemo and radiation therapy. After 36 mo, there is no disease progression and the patient is in good health, clinically stable and without significant chest pain. PMID:25493248

The patient of this report underwent a right thoracotomy to extract the projectile as well as a wedge resection of the injured lung parenchyma. This case demonstrates that even supposedly safe riot control munition fired at close range, at the torso, can provoke serious injury. Therefore a thorough investigation and close clinical supervision are justified. PMID:19555511

Pulmonary tuberculosis has become a rare indication for surgical intervention in all industrial nations. Over a period of 10 years we overview 193 patients who were suffering this disease and underwent thoracotomy. Main indication (79.8 %) was pulmonary nodules, of unknown origin. In this cases wedge resection was performed. Expanded resectional techniques were necessary in cases of cavernes, superinfected bronchiectasis, bronchial stenosis, hemoptysis and destroyed lungs due to tuberculosis. Considering the heterogenous groups of patients, the perioperative morbidity (21.8 %) and mortality (0.5 %) has to be regarded in comparison to the data found in the literature.

The fissureless lobectomy or anterior fissureless technique is a novel surgical technique, which avoids dissection of the lung parenchyma over the pulmonary artery during lobectomy by open thoracotomy approach or direct vision thoracoscopic surgery. This technique is indicated for fused lobes. We present two cases where thoracoscopic pulmonary segmentectomy was performed using the fissureless technique simulated by three-dimensional (3D) pulmonary models. The 3D model and rapid prototyping provided an accurate anatomical understanding of the operative field in both cases. We believe that the construction of these models is useful for thoracoscopic and other complicated surgeries of the chest. PMID:24633132

A 25-year-old man presented with a 2-month history of dysphagia and past history of pulmonary and intestinal tuberculosis. A barium swallow showed a point of constriction 42 mm above the gastroesophageal junction. Computed tomography revealed large opacities in bilateral lung fields, encroaching more on the esophagus. The lesion progressively compressed the esophagus as it moved inferiorly. A right posterolateral thoracotomy was performed for sub-anatomical resection of the mass. A biopsy revealed homogenous whirling hyalinized collagen fibers, highly suggestive of pulmonary hyalinizing granuloma, with no evidence of malignancy. Pulmonary hyalinizing granuloma should be considered in the differential diagnosis of longstanding dysphagia.

The present report provides a detailed description of the surgical methods for primary spontaneous pneumothorax (PSP) treatment, from open surgery (thoracotomy) to minimally invasive procedures (video-assisted thoracoscopic surgery – VATS). It describes the methods of preventing pneumothorax recurrence, including partial or complete resection of the parietal pleura and chemical pleurodesis with VATS. The pros and cons of each method are presented. The paper also discusses new techniques for diagnosing pneumothorax, such as fluorescein-enhanced autofluorescence thoracoscopy (FEAT) and infrared thoracoscopy. Finally, the authors propose their own algorithm for the treatment of PSP. PMID:28096830

Liposarcoma is the second most common soft tissue sarcoma after malignant fibrous histiocytoma in adults. It is frequently found in the extremities and retroperitoneum; rarely it can be seen in the chest wall. We report a rare case of giant liposarcoma originating from the chest wall representing a transformation of a relapsing lipoma in the same region. We performed chest wall resection, reconstruction with latissimus dorsi muscle transposition via posterolateral thoracotomy. The patient received 4 series of adjuvant chemotherapy after the postoperative diagnosis of dedifferentiated liposarcoma. The patient had no postoperative complication and has remained disease-free for 30 months.

Late clotted haemothorax after blunt chest trauma.

PubMed Central

Sinha, P; Sarkar, P

1998-01-01

A clotted haemothorax can develop any time after blunt chest trauma. Two cases are described in which late clotted haemothoraces developed which were treated by limited thoracotomy and evacuation of clots. Late clotted haemothorax may occur even in the absence of any abnormal initial clinical findings. Early detection and treatment is important to avoid the complications of fibrothorax and empyema with permanent pulmonary dysfunction. After blunt chest trauma patients should be advised to return to the accident and emergency department for assessment on development of any new chest symptom. Under these circumstances a chest x ray is mandatory to exclude a haemothorax. Images Figure 1 PMID:9639184

Spontaneous massive haemothorax is rare. We describe a healthy 44 year old woman who experience sudden onset chest pain while sleeping. Chest radiograph revealed massive right pleural effusion. Progressive dyspnoea, cold sweating, and tachycardia developed later. A tube thoracostomy was performed immediately and massive haemothorax was noted. An emergency thoracotomy was performed because of unstable vital signs. Disruption of the right third intercostal vein with continuous bleeding was observed, and suture ligation of the vein was performed. The total blood loss was about 4000 ml. The patient recovered uneventfully, and her condition at follow up visits to the outpatient department was satisfactory. PMID:16921070

Swallowed button batteries (BB) which remain lodged in the oesophagus are at risk of serious complications, particularly in young children. The authors report a 3-year-old child, who rapidly developed an oesophageal perforation, following the ingestion of a 20-mm lithium BB which was initially mistaken for a coin. A thoracotomy and T-tube management of the perforation led to a positive outcome. BBs (20 mm) in children should be removed quickly and close observation is required as the damage initiated by the battery can lead to a significant injury within a few hours.

Parosteal lipoma derived from the rib is extremely rare and is usually resected through open thoracotomy despite its benign nature. A 33-year-old man who had no symptoms was referred to our hospital for treatment of a 30-mm chest wall mass that has slightly increased in size during 2 years of follow-up. En bloc resection of the tumor with parts of the 3rd and 4th ribs was performed through a complete thoracoscopic approach using orthopedic electric micro drill. This was the first report on a case of parosteal lipoma of the rib that was resected by a complete thoracoscopic procedure.

The management of oesophageal atresia and tracheo-oesophageal atresia (OATOF) is very challenging. While in developed countries survival of patients with this condition has improved, the outcome in many developing countries has been poor. Primary repair through a thoracotomy (or video-assisted thoracoscopic surgery where available) is the gold standard treatment of OATOF. However, in our setting where patients typically present late and with minimum support resources such as Neonatal Intensive Care Unit and total parenteral nutrition; staged repair may be the only hope of survival of these patients and this communication highlights the essential steps of this mode of treatment.

2015-01-01

Tuberculosis (TB) is well known as a diagnostic chameleon and can resemble malignancy. In thorax TB can be manifested as pulmonary infiltrates and/or mediastinal lymphadenopathy. In low incident countries with high incidence of lung cancer and varying clinical presentations, TB often gets misdiagnosed with the result of delayed treatment start and unnecessary diagnostic procedures. Our case report presents two patients, who were referred to the Thorax diagnostic centre at the Department of Respiratory Medicine, Odense University Hospital, with presumptive diagnosis of neoplasm and had proved lung TB with no evidence of malignancy instead. In the first case diagnosis was confirmed after thoracotomy, in the second case after bronchoscopy. PMID:26744652

Esophageal cancer surgery is traditionally performed by a number of open surgical approaches. Open approaches require thoracotomy and laparotomy. Developments in instrumentation and optics have allowed the use of minimally invasive approaches to esophageal cancer, which had been traditionally managed by open operation. Minimally invasive surgery (MIS) avoids thoracotomy and laparotomy and results in quicker return to normal functions and less morbidity. In this prospective study, we compared the immediate surgical and oncologic outcomes of patients who have undergone MIS with those who have had open surgery. From November 1, 2003 to March 30, 2006, 62 cases of carcinoma esophagus were operated in Surgical unit 3 (MIS unit) in the institute. Out of the 62 patients, 34 (54.8%) underwent minimally invasive esophagectomy (MIE), and the remaining 28 patients (45.2%) underwent open surgery. Both operations were done by the same team of surgeons. The groups were compared in terms of perioperative outcomes, morbidity, mortality, and adequacy of oncologic excision. The average duration for MIS was 312.35 min (60-480 min), which was more than that of open group surgery whose average duration was 261.96 min (60-360 min). This difference was found to be not significant (P < 0.110). The average blood loss was 275.74 mL (200-500 mL) in minimally invasive group compared with 312.50 (200-500 mL) in open group (P-value 0.33). Four patients (11.76%) in MIS group had been converted to open surgery. Average duration of hospitalization was 11.9 (4-24) days in MIS group compared with 12.19 (5-24) days in open group (P-value 0.282). Nine (26.47%) patients in MIS group had developed major or minor morbidity. Similarly, eight (28.57%) patients in open group had morbidity. One patient each expired in each group. The morbidity and mortality rates were not statistically significant. There were four leaks (11.76%) in MIS group and three leaks (10.71%) in open group (P-value 0.85). Regarding the extent of nodal clearance, an average number of 9.5 (0-19) nodes were removed in MIS group compared with an average of 7.26 (0-12) nodes in open group (P-value 0.05). Better visibility and magnification enabled more number of lymph nodes to be removed in MIS group. MIE is oncologically safe compared with open surgery. It has almost similar postoperative course, morbidity pattern, and duration of hospital stay as open surgery. Increased duration of procedure compared with open surgery is a disadvantage of MIS, especially in the early part of learning curve. © 2011 Copyright the Authors.

Local anaesthetics and regional anaesthesia for preventing chronic pain after surgery

PubMed Central

Andreae, Michael H; Andreae, Doerthe A

2014-01-01

Background Regional anaesthesia may reduce the rate of persistent (chronic) pain after surgery, a frequent and debilitating condition. Objectives To compare local anaesthetics and regional anaesthesia versus conventional analgesia for the prevention of persistent pain six or 12 months after surgery. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 4), PubMed (1966 to April 2012), EMBASE (1966 to May 2012) and CINAHL (1966 to May 2012) without any language restriction. We used a combination of free text search and controlled vocabulary search. The results were limited to randomized controlled clinical trials (RCTs). We conducted a handsearch in reference lists of included trials, review articles and conference abstracts. Selection criteria We included RCTs comparing local anaesthetics or regional anaesthesia versus conventional analgesia with a pain outcome at six or 12 months after surgery. Data collection and analysis Two authors independently assessed trial quality and extracted data, including information on adverse events. We contacted study authors for additional information. Results are presented as pooled odds ratios (OR) with 95% confidence intervals (CI), based on random-effects models (inverse variance method). We grouped studies according to surgical interventions. We employed the Chi2 test and calculated the I2 statistic to investigate study heterogeneity. Main results We identified 23 RCTs studying local anaesthetics or regional anaesthesia for the prevention of persistent (chronic) pain after surgery. Data from a total of 1090 patients with outcomes at six months and of 441 patients with outcomes at 12 months were presented. No study included children. We pooled data from 250 participants after thoracotomy, with outcomes at six months. Data favoured regional anaesthesia for the prevention of chronic pain at six months after thoracotomy with an OR of 0.33 (95% CI 0.20 to 0.56). We pooled two studies on paravertebral block for breast cancer surgery; the pooled data of 89 participants with outcomes at five to six months favoured paravertebral block with an OR of 0.37 (95% CI 0.14 to 0.94).The methodological quality of the included studies was intermediate. Adverse effects were not studied systematically and were reported sparsely. Clinical heterogeneity, attrition and sparse outcome data hampered the assessment of effects, especially at 12 months. Authors’ conclusions Epidural anaesthesia may reduce the risk of developing chronic pain after thoracotomy in about one patient out of every four patients treated. Paravertebral block may reduce the risk of chronic pain after breast cancer surgery in about one out of every five women treated. Our conclusions are significantly weakened by performance bias, shortcomings in allocation concealment, considerable attrition and incomplete outcome data. We caution that our evidence synthesis is based on only a few, small studies. More studies with high methodological quality, addressing various types of surgery and different age groups, including children, are needed. PMID:23076930

[Surgical treatment of thoracic disc herniation].

Hrabálek, L; Kalita, O; Langová, K

2010-08-01

The aim of this study was to compare the efficiency of different surgical approaches to thoracic disc herniation, and to show the role of segmental fusion and selection of an appropriate microsurgical decompression technique for the successful outcome of surgery. A group of 27 patients, 10 men and 17 women, between 31 and 70 years (average age, 49.33 years) were included in this prospective study. They underwent surgery for thoracic degeneration disc disease in the period from June 1994 to August 2008. In all patients, the severity of myelopathy was assessed using the grading Frankel system and JOA score, axial and radicular pain intensity was evaluated with VAS and ODI rating systems. The diagnosis was established on the basis of thoracic spine radiography, thoracic spine MRI and a CT scan of the segment. A total of 30 thoracic segments, in the range of Th4/Th5 to Th12/L1, were indicated for surgery. Localisation of the hernia was medial at 19 segments, mediolateral at three and lateral at eight segments. Soft disc herniation was found in 17 cases and hard disc protrusion at the remaining 13 segments. Surgery for significant myelopathy was carried out in 23 patients and for pain in four patients. According to the surgical procedure used, the patients were allocated to two groups: group A comprised 10 patients treated without disc replacement through a laminectomy or a costotransversectomy exposure, and group B consisted of 17 patients undergo- ing intersomatic fusion via a thoracotomy. Clinical and radiographic examinations were made at regular intervals for at least 1 year of follow-up. The results of clinical assessment, including JOA scores, JOA Recovery Rate, VAS scores at rest and after exercise and ODI, were statistically analysed for each group and compared. There was a statistically significant difference in JOA evaluation of myelopathy between the groups in group A, the mean JOA score declined from 7.9 to 7.0, i.e., -0.9 point, while in group B it increased from 6.71 to 9.12, i.e., +2.41 points. The mean JOA Recovery Rate did not reach a plus value in group A, while in group B it improved by 55 %. JOA Recovery Rate: Of the seven patients in group A evaluated for myelopathy, a fair result was in one, unchanged in two and worse in four patients. Of the 16 patients evaluated for myelopathy in group B, the results were excellent in four, good in six, fair in four and unchanged in two patients. Frankel grade function: In group A, one patient improved by one grade, two remained unchanged, two deteriorated by one grade and two by two grades. In group B, five patients improved by one grade, two patients by two grades and two patients by three grades. Eight patients remained unchanged and no patient deteriorated. The post-operative pain intensity, as assessed by the mean VAS score, was lower at rest and after exercise in both groups; the score was better in group B, but the difference was not statistically significant. The ODI was evaluated only in group B its mean value improved from 41.4% to 26.1%, i.e., by 15.3%. Between 7 to 15 % of the patients have asymptomatic thoracic disc herniation, while symptomatic herniation is very rare and accounts for only 0.25 % to 0.57 % of herniated discs in the whole spine. Severe or progressive myelopathy is a clear indication for surgical intervention in thoracic disc herniation, but the role of surgery in pain control is controversial. There are five approaches for thoracic disc herniation. Transpleural anterolateral thoracotomy has an advantage over the other methods because it permits the treatment of all types of herniation, whether localised centrally, laterally or contralaterally, i.e., soft, calcified or sequestered intradural disc herniation. The results of treatment will depend on the outcome of surgical spinal cord decompression and the degree of spinal stabilisation achieved. The surgical procedure via thoracotomy with intersomatic fusion resulted in a statistically more significant improvement of myelopathy than the posterior approach without disc replacement, and it provided greater pain relief. The authors recommend to treat thoracic disc herniation by discectomy via a thoracotomy and by intersomatic fusion.

We diagnosed the patient with primary neuroendocrine cell carcinoma and squamous cell carcinoma of the esophagus. Following 2 courses of CDDP+5-FU+ADM combination neoadjuvant chemotherapy, the primary tumor had reduced in size. Thereafter, we performed subtotal esophagectomy by right thoracotomy, retrosternal gastric tube reconstruction, and 2-field lymph node dissection. Computed tomography scan 3 months after the surgery revealed lung metastasis. He received CPT-11+CDDP chemotherapy, and the disease was diagnosed as cCR. At present, he is alive without any evidence of recurrence 12 months after the surgery.

Upside-down stomach syndrome is a rare type of a large paraoesophageal hiatal hernia, which requires an immediate surgical treatment in case of incarceration. The authors present a case report of a 53-year-old male patient with gastric volvulus related to the upside-down stomach syndrome. Surgical treatment was complicated by an injury to distal oesophagus, which was successfully treated using a self-expandable metallic stent among other methods. Despite the complicated postoperative course with a necessity of reoperation, insertion of an oesophageal stent, thoracotomy for a mediastinal abscess and secondary healing of the laparotomy, the patient was discharged in a good condition with healed oesophageal perforation and laparotomy after 52 days.

Actinomyces meyeri is an uncommon cause of actinomycosis. We present a patient with pneumonia and empyema due to A. meyeri. The patient underwent open thoracotomy with decortication and was discharged home on a twelve-month course of oral penicillin. Review of the English literature revealed thirty-two cases of infection due to A. meyeri. The majority of patients were male, and a significant number had poor dental hygiene and a history of alcoholism. More than other Actinomyces species, A. meyeri causes pulmonary infection and has a predilection for dissemination. Prognosis is favorable with prolonged penicillin therapy combined with surgical debridement, if needed. Copyright © 2012 The British Infection Association. Published by Elsevier Ltd.

We describe a two-stage surgical approach in a patient with cardiac dysfunction and hemodynamic compromise resulting from a massive and compressive mediastinal bronchogenic cyst. To drain this cyst, video-assisted mediastinoscopy was performed as an emergency procedure, which immediately improved the patient's cardiac function. Five days later and under video thoracoscopy, resection of the cyst margins was impossible because the cyst was tightly adherent to the left atrium. We performed deroofing of this cyst through a right thoracotomy. The patient had an uncomplicated postoperative recovery, and no recurrence was observed at the long-term follow-up visit.

2014-01-01

A 23-year-old male underwent a left internal jugular vein catheterization during extended surgery for treatment of multiple fractures due to a traffic accident. Although the catheterization was performed under ultrasound (US) guidance, iatrogenic perforation of the central vein and pleura occurred. The catheter was removed, and the perforated site was addressed under thoracoscopy rather than an open thoracotomy. This case suggests that using US does not completely guarantee a complication-free outcome, and that catheter placement should be carefully confirmed. In addition, this case suggests that thoracoscopy may be an ideal method of resolving a perforation of the central vein and pleura. PMID:24851167

Mitral repair and the robot: a revolutionary tool or marketing ploy?

2018-03-01

In this review, we discuss the current evidence supporting each minimally invasive mitral repair approach and their associated controversies. Current evidence demonstrates that minimally invasive mitral repair techniques yield similar mitral repair results to conventional sternotomy with the benefits of shorter hospital stay, quicker recovery, better cosmesis and improved patient satisfaction. Despite this, broad adoption of minimally invasive mitral repair is still not achieved. Two main approaches of minimally invasive mitral repair exist: endoscopic mini-thoracotomy and robotic-assisted approaches. Both minimally invasive approaches share many commonalities; however, most centres are strongly polarized to one approach over another creating controversy and debate about the most effective minimally invasive approach.

A solitary papilloma versus the usual multiple lesions of papillomatosis is extremely rare. Even more infrequent is a solitary papilloma of the trachea in an adult patient. In the present report, a case of a solitary papilloma in the distal trachea is presented. After two unsuccessful sessions of laser ablation, resection of the lower one-third of the trachea was performed through a right posterolateral thoracotomy. Postoperative histology results disclosed a malignant degeneration into squamous cell carcinoma. The patient had an excellent outcome after resection of the affected portion of the trachea. There was no evidence of recurrence after 20 months of follow-up. PMID:18949108

Massive haemothorax is a relatively rare complication of thoracocentesis or the placement of tube thoracostomy. It is principally caused by intercostal vessel injury. The therapeutic approach consists in pleural drainage and sometimes thoracotomy for haemostasis. We describe a frail 72 year old patient, who developed a massive haemothorax occurring after a tube thoracostomy placing, persisting despite second pleural drainage, and complicated by deep haemodynamic shock. He was considered to have a very high risk of mortality if surgery was undertaken. Haemorrhage was totally stopped after intercostal instillation of lidocaïne-adrenaline. This case report suggests a role for pleural vasoconstrictor injection as initial treatment in case of persistent pleural haemorrhage caused by intercostal vessel injury.

A 51-year-old man was referred to our institution for patent ductus arteriosus (PDA) complicated by left ventricular dysfunction and pulmonary hypertension. Surgical closure of a PDA is usually carried out via a small posterior thoracotomy. However, thoracoscopic procedures are probably not appropriate in adults because of the frequency of calcification and the greater risk of rupture while ligating the ductus. To minimize surgical trauma, we used hybrid endovascular stent grafting combined with revascularization of the left subclavian artery, which enabled us to eliminate shunt flow to the pulmonary artery. At 11-month follow-up, the patient was asymptomatic and showed no complications. © Georg Thieme Verlag KG Stuttgart · New York.

Penetrating cardiac injury by wire thrown from a lawn mower.

Rubio, P A; Reul, G J

1979-01-01

The first successful surgically treated case of penetrating heart injury, specifically the right ventricle, caused by a fragment of coat hanger wire thrown by a lawn mower, is reported. Though traumatic heart injuries are rare, this case represents accurate surgical management and judgment, especially in the preoperative phase which resulted in early operating and excellent postoperative results. It is our feeling that if the patient can be transferred safely to the operating room the mortality rate is considerably lowered; however, emergency room thoracotomy, which will undoubtedly result in a greater survival rate from these spectacular injuries, should be performed in the emergency center if cardiac activity ceases or the patient's condition deteriorates considerably.

As an OR staff nurse at Cook County Hospital, some of my most challenging and rewarding nursing experiences have come from caring for emergency open-chest trauma patients. From the moment we receive a call that an open-chest patient is on the way, everyone assigned is in a high state of tension. Every decision takes on exaggerated importance. The circulating nurse, by virtue of his or her position during an emergency, is the "hub of the wheel" of activity. He or she is privy to all facets of care that are being administered to the patient. The nursing challenge of the emergency open-chest trauma is great, but it is not an impossible task.

Ga-PSMA-11 PET/CT was performed in a 74-year-old man because of biochemical recurrence of prostate cancer following radiation therapy of the prostate gland 24 months earlier. Besides focal nuclide accumulation in the prostate gland suggestive of local recurrence, PET scan revealed no further pathologic uptake. However, CT showed multiple pulmonic nodules suggestive of metastases. Thoracotomy and pathologic examination revealed the nodules to be prostate cancer metastasis. Furthermore, immunohistochemical staining with PSMA antibodies demonstrated a virtual lack of PSMA expression. This case demonstrates the possibility of PSMA-negative metastases of prostate cancer an important pitfall that should be known to physicians interpreting PSMA PET.

Patients with solid tumors frequently undergo surgical procedures and develop procedure-related infections. We sought to describe the current microbiologic spectrum of infections at various sites following common surgical procedures. This was a retrospective review of microbiologic data between January 2011 and February 2012. The sites studied were those associated with breast cancer surgery, thoracotomy, craniotomy, percutaneous endoscopic gastrostomy (PEG) tube insertion, and abdominal/pelvic surgery. Only patients with solid tumors were included. A total of 368 surgical site infections (SSIs) were identified (68 breast cancer related; 91 thoracotomy related; 45 craniotomy related; 75 PEG-tube insertion related; and 89 abdominal/pelvic surgery related). Of these, 58% were monomicrobial and 42% were polymicrobial. Overall, 85% of the 215 monomicrobial infections were caused by Gram-positive organisms and 13% by Gram-negative bacilli (GNB). Staphylococcus aureus was the predominant pathogen in monomicrobial infections (150 of 215, 70%). Sixty (40%) of these staphylococcal isolates were methicillin resistant (MRSA), and 65% had a vancomycin minimal inhibitory concentration (MIC) ≥1.0 µg/ml. Pseudomonas aeruginosa was the predominant GNB pathogen (19 of 27, 70%). Staphylococci were also the predominant pathogens in polymicrobial infections, while P. aeruginosa and Escherichia coli were the predominant GNB. Overall, 35% of isolates from polymicrobial infections were GNB. Cephalosporins (e.g., cefazolin) or amoxicillin/clavulanate was used most often for surgical prophylaxis, and 47% of organisms from monomicrobial infections (MRSA, P. aeruginosa) were resistant to them. A similar resistance pattern was observed in polymicrobial infections. Staphylococcus species were isolated most often from the sites studied. Polymicrobial infections (42%) and GNB monomicrobial infections (13%) were relatively frequent causes of SSIs. Many of these infections were caused by organisms that are resistant to agents commonly used for surgical prophylaxis. Additionally, 65% of staphylococcal isolates had a vancomycin MIC ≥1.0 µg/ml, suggesting the need for alternative therapeutic agents.

Open cervical parathyroidectomy is the standard of care for the treatment of primary hyperparathyroidism (PHP). However, in patients with a history of keloid or hypertrophic scar formation, the cosmetic result may sometimes be unsatisfactory. Furthermore, in the presence of mediastinal glands, a more morbid approach is sometimes necessary, involving a sternal split or thoracotomy. Robotic parathyroidectomy, either transaxillary or transthoracic, could be an alternative in both settings. Between 2008 and 2013, 14 patients with PHP and a well-localized single adenoma underwent robotic transaxillary cervical (TAC) (n = 8) or transthoracic mediastinal (TTM) (n = 6) parathyroidectomy at an academic tertiary medical center and their outcomes were analyzed. All 14 operations were completed successfully as planned. For TAC and TTM parathyroidectomies, mean operative time was 184 and 168 min, respectively. With the exception of one TTM patient, intraoperative PTH determination indicated a >50 % drop in all patients 10 min after excision and no patients presented with recurrent disease on follow-up. Average length of hospital stay was 1 day after TAC parathyroidectomy and 2.2 days after TTM. On a visual analog pain scale (0-10), average pain scores after TAC were 6/10 on postoperative day 1 and 1/10 on day 14, compared to 7.7/10 and 1.5/10, respectively, after TTM. Complications included development of seroma in 1 patient in the TAC group and pericardial and pleural effusion in 1 patient in the TTM cohort. This initial study shows that robotic TAC and TTM parathyroidectomy are feasible in selected PHP patients with preoperatively well-localized disease. Although the TAC approach offers a potential cosmetic benefit in patients with a history of keloid or hypertrophic scar formation, a more generalized use cannot be recommended based on current evidence. The robotic TTM approach presents a minimally invasive alternative to resections previously performed through thoracotomy and sternotomy.

The feasibility of a randomized controlled trial of esophagectomy for esophageal cancer - the ROMIO (Randomized Oesophagectomy: Minimally Invasive or Open) study: protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background There is a need for evidence of the clinical effectiveness of minimally invasive surgery for the treatment of esophageal cancer, but randomized controlled trials in surgery are often difficult to conduct. The ROMIO (Randomized Open or Minimally Invasive Oesophagectomy) study will establish the feasibility of a main trial which will examine the clinical and cost-effectiveness of minimally invasive and open surgical procedures for the treatment of esophageal cancer. Methods/Design A pilot randomized controlled trial (RCT), in two centers (University Hospitals Bristol NHS Foundation Trust and Plymouth Hospitals NHS Trust) will examine numbers of incident and eligible patients who consent to participate in the ROMIO study. Interventions will include esophagectomy by: (1) open gastric mobilization and right thoracotomy, (2) laparoscopic gastric mobilization and right thoracotomy, and (3) totally minimally invasive surgery (in the Bristol center only). The primary outcomes of the feasibility study will be measures of recruitment, successful development of methods to monitor quality of surgery and fidelity to a surgical protocol, and development of a core outcome set to evaluate esophageal cancer surgery. The study will test patient-reported outcomes measures to assess recovery, methods to blind participants, assessments of surgical morbidity, and methods to capture cost and resource use. ROMIO will integrate methods to monitor and improve recruitment using audio recordings of consultations between recruiting surgeons, nurses, and patients to provide feedback for recruiting staff. Discussion The ROMIO study aims to establish efficient methods to undertake a main trial of minimally invasive surgery versus open surgery for esophageal cancer. Trial registration The pilot trial has Current Controlled Trials registration number ISRCTN59036820(25/02/2013) at http://www.controlled-trials.com; the ROMIO trial record at that site gives a link to the original version of the study protocol.

To describe perioperative management of calves that underwent left lateral thoracotomy, aortic cross-clamping, partial left heart bypass and implantation of a left ventricular assist device. A total of 43 healthy castrated male calves, weighing 121 +/- 24 kg. Diazepam (mean +/- SD, 0.26 +/- 0.07 mg/kg), ketamine (5.9 +/- 2.17 mg/kg) and isoflurane were used in the anesthetic management of calves undergoing implantation of a left ventricular assist device in the descending thoracic aorta. Other adjunctive agents administered were fentanyl (11 +/- 5.4 microg/kg), lidocaine (4.9 +/- 3.19 mg/kg), bupivacaine (0.75%) and butorphanol (0.49 +/- 0.13 mg/kg). None of the calves regurgitated at induction or during intubation. A tube was used to drain the rumen and prevent bloat during the procedure. Partial left heart bypass was used to perfuse the caudal half of the body during the period of aortic cross clamp and device implantation. Initial mean systemic blood pressure was 96 +/- 25 mm Hg, and pressures measured in the auricular artery increased during aortic cross-clamping and bypass. Vasoconstrictor therapy was required to treat caudal arterial hypotension during the procedure in 9 calves. Mean systemic arterial pressures returned to baseline values by the end of the anesthetic period. Initial mean pulmonary arterial pressures (PAP) were 22 +/- 3 mm Hg. A significant but transient increase in pulmonary arterial pressure occurred after both heparin and protamine administration. The described anesthetic protocol was effective for thoracotomy and implantation of an intra-aortic left ventricular assist device in normal calves. Partial left ventricular bypass was a useful adjunct during the period of aortic cross clamp. The doses of heparin and protamine administered were effective. Responsibility to monitor oxygenation of the cranial half of the animal continues during the bypass period as hypoxemia due to pulmonary dysfunction will not be detected by the perfusionist.

Complex hepatic injuries grades IV-V are highly lethal. The objective of this study is to assess the multidisciplinary approach for their management and to evaluate if survival could be improved with this approach. Prospective 54-month study of all patients sustaining hepatic injuries grades IV-V managed operatively at a Level I Trauma Center. survival. univariate and stepwise logistic regression. Seventy-five patients sustained penetrating (47/63%) and blunt (28/37%) injuries. Seven (9%) patients underwent emergency department thoracotomy with a mortality of 100%. Out of the 75 patients, 52 (69%) sustained grade IV, and 23 (31%) grade V. The estimated blood loss was 3,539+/-3,040 ml. The overall survival was 69%, adjusted survival excluding patients requiring emergency department thoracotomy was 76%. Survival stratified to injury grade: grade IV 42/52-81%, grade V 10/23-43%. Mortality grade IV versus V injuries (p < 0.002; RR 2.94; 95% CI 1.52-5.70). Risk factors for mortality: packed red blood cells transfused in operating room (p=0.024), estimated blood loss (p < 0.001), dysryhthmia (p < 0.0001), acidosis (p = 0.051), hypothermia (p = 0.04). The benefit of angiography and angioembolization indicated: 12% mortality (2/17) among those that received it versus a 36% mortality (21/58) among those that did not (p = 0.074; RR 0.32; 95% CI 0.08-1.25). Stepwise logistic regression identified as significant independent predictors of outcome: estimated blood loss (p= 0.0017; RR 1.24; 95% CI 1.08-1.41) and number of packed red blood cells transfused in the operating room (p = 0.0358; RR 1.16; 95% CI 1.01-1.34). The multidisciplinary approach to the management of these severe grades of injuries appears to improve survival in these highly lethal injuries. A prospective multi-institutional study is needed to validate this approach.

Age is an important risk factor for morbidity after lung resection. This study was performed to identify specific risk factors for complications after lung resection in octogenarians. A prospective database containing patients aged 80 years or older, who underwent lung resection at a single institution between January 2000 and June 2009, was reviewed. Preoperative, histopathologic, perioperative, and outcome variables were assessed. Morbidity was measured as a patient having any perioperative event as defined by the Society of Thoracic Surgeons General Thoracic Surgery Database. A multivariable risk model for morbidity was developed using a panel of established preoperative and operative variables. Survival was calculated using the Kaplan-Meier method. During the study period, 193 patients aged 80 years or older (median age 82 years) underwent lung resection: wedge resection in 77, segmentectomy in 13, lobectomy in 96, bilobectomy in four, and pneumonectomy in three. Resection was accomplished via thoracoscopy in 149 patients (77%). Operative mortality was 3.6% (seven patients) and morbidity was 46% (89 patients). A total of 181 (94%) patients were discharged directly home. Postoperative events included atrial arrhythmia in 38 patients (20%), prolonged air leak in 24 patients (12%), postoperative transfusion in 22 patients (11%), delirium in 16 patients (8%), need for bronchoscopy in 14 patients (7%), and pneumonia in 10 patients (5%). Significant predictors of morbidity by multivariable analysis included resection greater than wedge (odds ratio 2.98, p=0.006), thoracotomy as operative approach (odds ratio 2.6, p=0.03), and % predicted forced expiratory volume in 1s (odds ratio 1.28 for each 10% decrement, p=0.01). Octogenarians can undergo lung resection with low mortality. Extent of resection, use of a thoracotomy, and impaired lung function increase the risk of complications. Careful evaluation is necessary to select the most appropriate approach in octogenarians being considered for lung resection. Copyright © 2010 European Association for Cardio-Thoracic Surgery.

The hybrid SPIDER-graft consists of a proximal descending aortic stent graft and a conventional six branched Dacron graft for open abdominal aortic repair. Technical feasibility with regard to avoiding thoracotomy and extracorporeal circulation (ECC) during thoraco-abdominal aortic hybrid repair and peri-procedural safety of this novel device are unknown. This was a feasibility and safety study in domestic pigs (75-85 kg). The abdominal aorta including iliac bifurcation, left renal artery, and visceral arteries were exposed via retroperitoneal access. The right iliac branch was first temporarily anastomosed end to side to the distal aorta via partial clamping. During inflow reduction and infra-coeliac cross-clamping, the coeliac trunk (CT) was divided and the proximal stent graft portion of the SPIDER-graft was deployed into the descending aorta via the CT ostium. Retrograde visceral and antegrade aorto-iliac blood flow was maintained via the iliac side branch. The visceral, renal, and iliac arteries were sequentially anastomosed, finally replacing the first iliac end to side anastomosis. Technical success, blood flow, periods of ischaemia, and peri-procedural complications were evaluated after intra-operative completion angiography and post-operative computed tomography angiography. Six animals underwent successful thoracic stent graft deployment and distal open reconstruction without peri-operative death. The median thoracic graft implantation time was 4.5 min, and the median ischaemia times before reperfusion were 10 min for the CT, 8 min for the superior mesenteric artery, 13 min for the right renal artery, and 22 min for the left renal artery. Angiography demonstrated appropriate graft implantation and blood flow measurements confirmed sufficient blood flow through all side branches. In this translational pig model, thoraco-abdominal hybrid repair using the novel SPIDER-graft was successful in avoiding thoracotomy and ECC. Technical feasibility and safety appear promising, but need to be reassessed in humans. Copyright © 2017. Published by Elsevier Ltd.

Prolonged air leak increases costs and worsens outcomes after pulmonary resection. We aimed to develop a clinical prediction tool for prolonged air leak using pretreatment and intraoperative variables. Patients who underwent pulmonary resection for lung cancer/nodules (from January 2009 to June 2014) were stratified by prolonged parenchymal air leak (>5 days). Using backward stepwise logistic regression with bootstrap resampling for internal validation, candidate variables were identified and a nomogram risk calculator was developed. A total of 2317 patients underwent pulmonary resection for lung cancer/nodules. Prolonged air leak (8.6%, n = 200) was associated with significantly longer hospital stay (median 10 vs 4 days; P < .001). Final model variables associated with increased risk included low percent forced expiratory volume in 1 second, smoking history, bilobectomy, higher annual surgeon caseload, previous chest surgery, Zubrod score >2, and interaction terms for right-sided thoracotomy and wedge resection by thoracotomy. Wedge resection, higher body mass index, and unmeasured percent forced expiratory volume in 1 second were protective. Derived nomogram discriminatory accuracy was 76% (95% confidence interval [CI], 0.72-0.79) and facilitated patient stratification into low-, intermediate- and high-risk groups with monotonic increase in observed prolonged air leaks (2.0%, 8.9%, and 19.2%, respectively; P < .001). Patients at intermediate and high risk were 4.80 times (95% CI, 2.86-8.07) and 11.86 times (95% CI, 7.21-19.52) more likely to have prolonged air leak compared with patients at low risk. Using readily available candidate variables, our nomogram predicts increasing risk of prolonged air leak with good discriminatory ability. Risk stratification can support surgical decision making, and help initiate proactive, patient-specific surgical management. Copyright © 2016 The American Association for Thoracic Surgery.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a less invasive method of proximal aortic occlusion compared with resuscitative thoracotomy with aortic cross-clamping (RTACC). This study compared time to aortic occlusion with REBOA and RTACC, both including and excluding time required for common femoral artery (CFA) cannulation. This was a retrospective, single-institution review of REBOA or RTACC performed between February 2013 and January 2016. Time of skin incision to aortic cross-clamp for RTACC, time required for CFA cannulation by percutaneous and open methods, and time from guide-wire insertion to balloon inflation at Zone 1 for REBOA, were obtained from videographic recordings. Eighteen RTACC and 21 REBOAs were performed. Median (Q1, Q3) time from skin incision to aortic cross-clamping was 317 seconds (227, 551 seconds). Median (Q1, Q3) time from start of arterial access to Zone 1 balloon occlusion was 474 seconds (431, 572 seconds) (vs. RTACC, p = 0.01). All REBOA procedures were performed with the same device. The median time to complete CFA cannulation was 247 seconds (range, 164-343 seconds), with no difference between percutaneous or open procedures (p = 0.07). The median (Q1, Q3) time to aortic occlusion in REBOA once arterial access had been established was 245 seconds (179, 295.5 seconds), which was significantly shorter than RTACC (p = 0.003). Once CFA access is achieved, time to aortic occlusion is faster with REBOA. Time to aortic occlusion is less than the time required to cannulate the CFA either by percutaneous or open approaches, emphasizing the importance of accurate and expedient CFA access. Resuscitative endovascular balloon occlusion of the aorta may represent a feasible alternative to thoracotomy for aortic occlusion. Time to aortic occlusion will likely decrease with the advent of newer REBOA technology. The rate-limiting portion of REBOA continues to be obtaining CFA access. Therapeutic, level V.

There is clinical equipoise regarding post-operative management of patients with patent ductus arteriosus (PDA) without insertion of a chest drain. This study evaluated post operative outcomes of chest closure with or without a drain following Patent Ductus Arteriosus ligation among childen at Uganda Heart Instritute (UHI). This was an open label randomized controlled trial of 62 children 12 years of age and below diagnosed with patent ductus arteriosus at Mulago National Teaching and Referral Hospital, Uganda. Participants were randomized in the ratio of 1:1 with surgical ligation of patent ductus arteriosus to either thoracotomy closure with a chest tube or without a chest tube. All participants received standard care and were monitored hourly for 24 hours then until hospital discharge. The combined primary endpoint consisted of significant pleural space accumulation of fluid or air, higher oxygen need or infection of the surgical site. Analysis was conducted by multivariable logistic regression analysis at 5 % significance level. We enrolled 62 participants, 46 (74 %) of whom were females. Their median age was 12 months (IQR: 8-36). Participants in the no-drain arm significantly had less post-operative complications compared to the drain arm (Unadjusted odds ratio [uOR]: 0.21, 95 % CI: 0.06-0.73, p = 0.015). This "protective effect" remained without statistical significance in the multivariable regression model (Adjusted odds ratio [aOR]: 0.07, 95 % CI: 0.00-2.50, p = 0.144). Children aged below 6 years with patent ductus arterious can safely and effectively have thoracotomy closure without using a drain in uncomplicated surgical ligation of the PDA. Chest drain was associated with post-operative complications. The trial was registered in the Pan African Clinical Trials registry on 1st/July/2012, retrospectively registered.

The authors report a case of a 25-year-old woman with a polytrauma, caused by a free fall of 12 metres in suicidal intention. Following endotracheal intubation and mechanical ventilation by an emergency physician at the scene, the patient was delivered to the emergency room of an university hospital. An ultrasonic check of the abdomen revealed free fluid in the abdominal cavity, and a rupture of liver and spleen was suspected. Since breath sounds over the right lung were diminished, a chest tube was inserted immediately in the fifth intercostal space in the anterior axillary line. About 300 millilitres of blood were drained by the tube. Shortly thereafter, a laparotomy was performed, where spleen and liver rupture were confirmed and treated. After 60 minutes, the patient developed severe hypotension coupled with ventricular tachycardia and fibrillation, and resuscitation measures had to be initiated. Since breath sounds over the right lung were missing, a tension pneumothorax was suspected and a thoracotomy performed immediately. While huge amounts of air and blood were emerging from the thoracic cavity, a rupture of the right mainstem bronchus as well as of the right pulmonary artery and vena subclavia was identified. The chest tube was found dislocated into the subcutaneous tissue. Despite of open heart compression, application of adrenaline and noradrenaline and substitution of packed red blood cells and of crystalloid and colloid solutions, all resuscitation measures failed so that the patient died shortly after on the operation table. This case illustrates first the difficulties of an adequate thoracic trauma management, particularly, when clinical symptoms are discrete, second the problems of the insertion and control of a chest tube, and third risks associated with wrong position or secondary dislocation which may include - as in our case - "masking" of severe injury patterns and delay of life-saving measures such as an immediate thoracotomy. In order to improve prognosis of patients with poly-/thoracic trauma, establishment of spiral-CT in emergency centres, routine bronchoscopy and safe handling of chest tubes may be helpful.

Erector spinae plane (ESP) block in the management of post thoracotomy pain syndrome: A case series.

2017-10-01

Post thoracotomy pain syndrome (PTPS) remains a common complication of thoracic surgery with significant impact on patients' quality of life. Management usually involves a multidisciplinary approach that includes oral and topical analgesics, performing appropriate interventional techniques, and coordinating additional care such as physiotherapy, psychotherapy and rehabilitation. A variety of interventional procedures have been described to treat PTPS that is inadequately managed with systemic or topical analgesics. Most of these procedures are technically complex and are associated with risks and complications due to the proximity of the targets to neuraxial structures and pleura. The ultrasound-guided erector spinae plane (ESP) block is a novel technique for thoracic analgesia that promises to be a relatively simple and safe alternative to more complex and invasive techniques of neural blockade. We have explored the application of the ESP block in the management of PTPS and report our preliminary experience to illustrate its therapeutic potential. The ESP block was performed in a pain clinic setting in a cohort of 7 patients with PTPS following thoracic surgery with lobectomy or pneumonectomy for lung cancer. The blocks were performed with ultrasound guidance by injecting 20-30mL of ropivacaine, with or without steroid, into a fascial plane between the deep surface of erector spinae muscle and the transverse processes of the thoracic vertebrae. This paraspinal tissue plane is distant from the pleura and the neuraxis, thus minimizing the risk of complications associated with injury to these structures. The patients were followed up by telephone one week after each block and reviewed in the clinic 4-6 weeks later to evaluate the analgesic response as well as the need for further injections and modification to the overall analgesic plan. All the patients had excellent immediate pain relief following each ESP block, and 4 out of the 7 patients experienced prolonged analgesic benefit lasting 2 weeks or more. The ESP blocks were combined with optimization of multimodal analgesia, resulting in significant improvement in the pain experience in all patients. No complications related to the blocks were seen. The results observed in this case series indicate that the ESP block may be a valuable therapeutic option in the management of PTPS. Its immediate analgesic efficacy provides patients with temporary symptomatic relief while other aspects of chronic pain management are optimized, and it may also often confer prolonged analgesia. The relative simplicity and safety of the ESP block offer advantages over other interventional procedures for thoracic pain; there are few contraindications, the risk of serious complications (apart from local anesthetic systemic toxicity) is minimal, and it can be performed in an outpatient clinic setting. This, combined with the immediate and profound analgesia that follows the block, makes it an attractive option in the management of intractable chronic thoracic pain. The ESP block may also be applied to management of acute pain management following thoracotomy or thoracic trauma (e.g. rib fractures), with similar analgesic benefits expected. Further studies to validate our observations are warranted. Copyright © 2017 Scandinavian Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.

Right ventricular failure (RVF) is an unfortunate complication that continues to limit outcomes following durable left ventricular assist device (LVAD) implantation. Despite several 'RVF risk scores' having been proposed, preoperative prediction of post-LVAD RVF remains a guesstimate at best. Current strategies for institution of temporary RVAD support are invasive, necessitate additional re-thoracotomy, restrict postoperative mobilization, and/or entail prolonged retention of prosthetic material in-situ. The authors propose a novel surgical strategy comprising simultaneous implantation of a permanent LVAD and percutaneous TandemHeart® plus ProtekDuo® to provide temporary RVAD support and preempt RVF in patients with impaired RV function.

(Video Assisted) thoracoscopic surgery: Getting started

2007-01-01

Thoracoscopic surgery without or with video assistance (VATS) is simpler and easier to learn as it seems to be. Potential benefits of the procedure in rural surgical environment are outlined while basic requirements and limitations are listed. Thoracoscopy kit, thoracotomy tray at hand, patient monitoring, proper drainage system, pain control and access to chest physiotherapy are the basic requirements. Having headlight, bronchoscope, Ligasure and mechanical staplers offer clear advantages but they are not indispensable. Exploration and evacuation of pleural space, pleurodesis, surgery for Stage I and II thoracic empyema are evidenced fields of VATS procedures. Some of the cases can be performed under controlled local anesthesia. Acute chest trauma cannot be recommended for VATS treatment. Lung cancer is out of the scope of rural surgery. PMID:19789679

A 75-year-old male who underwent an Ivor Lewis esophagectomy due to a distal adenocarcinoma had a leak at the gastroplasty on the 5th day after surgery, which required two surgeries and a primary suture. He was transferred to our hospital due to a poor outcome and endoscopy revealed a 2.5cm gap perianastomotically on the gastroplasty wall, for which a stent was placed. Due to hemodynamic impairment, a thoracotomy procedure was performed, which revealed stent protrusion into the cavity. The patient underwent an esophagogastric anastomosis resection, cervical esophagostomy and gastrostomy. Sepsis was resolved postoperatively and the patient had a protracted stay in the PACU due to poor respiratory dynamics following a prolonged intubation.

Rib fracture repair: indications, technical issues, and future directions.

2009-01-01

Rib fracture repair has been performed at selected centers around the world for more than 50 years; however, the operative indications have not been established and are considered controversial. The outcome of a strictly nonoperative approach may not be optimal. Potential indications for rib fracture repair include flail chest, painful, movable rib fractures refractory to conventional pain management, chest wall deformity/defect, rib fracture nonunion, and during thoracotomy for other traumatic indication. Rib fracture repair is technically challenging secondary to the human rib's relatively thin cortex and its tendency to fracture obliquely. Nonetheless, several effective repair systems have been developed. Future directions for progress on this important surgical problem include the development of minimally invasive techniques and the conduct of multicenter, randomized trials.

Mediastinal tuberculous lymphadenitis presenting as an esophageal intramural tumor: A very rare but important cause for dysphagia

Dysphagia associated with esophageal mechanical obstruction is usually related to malignant esophageal diseases. Benign lesions are rarely a cause for this type of dysphagia, and usually occur either as an intramural tumor or as an extrinsic compression. Mediastinal tuberculous lymphadenitis is rare in adults, and even more rarely causes dysphagia. We report two cases of dysphagia in adult patients caused by mediastinal tuberculous lymphadenitis, presenting radiologically and endoscopically as an esophageal submucosal tumor. Based on the clinical and imaging diagnosis, the patients underwent a right thoracotomy, and excision of the mass attached to and compressing the esophagus. Pathological examination of the specimens showed a chronic granulomatous inflammation with caseous necrosis, which was consistent with tuberculous lymphadenitis. PMID:18023110

Diving goitres can descend the cervical region expanding directly into the thoracic cavity. In most cases, diving goitres extend into the anterosuperior compartment, but they may also extend behind the trachea. We herein present a case of a male patient with retrotracheal goitre and history of left thyroid lobectomy and median sternotomy for thoracic aortic aneurysm repair with graft placement. After detailed preoperative evaluation, the patient underwent surgical resection of the mass through a combined approach; the existing cervical incision and a right posterolateral mini-thoracotomy. The postoperative course of the patient was uncomplicated. One year after surgery, the patient is asymptomatic and disease-free. (Folia Morphol 2018; 77, 1: 166-169).

Massive spontaneous hemothorax following combined thrombolytic and anticoagulant therapy for pulmonary embolism(PE) is a rare event that is little documented in the literature. Here, we describe a rare case of spontaneous hemothorax in a 23-year-old woman with underlying systemic lupus erythematosus following combined administration of tissue plasminogen activator and low-molecular-weight heparin for massive PE. This report of our successful treatment of this case by video-assisted thoracoscopic thoracotomy demonstrates that although the occurrence is rare, massive hemothorax following anticoagulant and/or thrombolytic therapy for PE should be suspected if patients experience chest pain, dyspnea, or signs of anemia, and follow-up physical examination and hemogram should be performed to facilitate diagnosis of this life-threatening complication.

Alveolar proteinosis is a rare chronic lung disease, especially in children, characterized by abnormal accumulation of lipoproteins and derived surfactant in the intra-alveolar space that generates a severe reduction of gas exchange. Idiopathic presentation form constitutes over 90% of cases, a phenomenon associated with production of autoimmune antibodies directed at the receptor for granulocyte-macrophage colony-stimulating factor. A case of a girl of 5 years of age treated because of atypical pneumonia with unfavorable evolution due to persistent hypoxemia is presented. The diagnosis is obtained through pathologic examination of lung biopsy by thoracotomy, as treatment is carried out by 17bronchopulmonary bronchoscopy lavages and the patient evidences marked clinical improvement.

Sarris, M; Georgoulis, J; Gatos, M; Dariotis, A

This is a case report of a successful repair of congenital diaphragmatic hernia in a 48 years old male that contained the transverse colon which was strangulated and ruptured in the left thoracic cavity. It was approached in two stages. First through a laparotomy the proximal part of the transverse colon was divided. The side going to the hernial sac was sutured and the proximal stump was anastomosed to the descending colon. In a second stage, two days later, through a felt thoracotomy the strangulated and ruptured colon was resected and the distal stump of the transverse colon was sutured and the hernia repaired.

Malignant disease is present in the pericardium of 1.5% to 20.6% of patients dying of malignant diseases as was examined postmortem. We present a case of a 57-year-old man with a history of Hodgkin's disease and a sarcoma of gluteus who presented with tachypnea, generalized weakness, and anasarca for 7 days. The echocardiogram revealed the presence of a significant pericardial thickening and localized pericardial effusion resulting from a tricuspid stenosis. A right anterior thoracotomy was performed, and a pericardiectomy (4 x 4 cm) was done. The histologic examination of the pericardium revealed the presence of a metastatic dissemination from a sarcoma. The cause for the clinical presentation and the treatment of malignant pericardial disease are discussed.

Clinico-Radiological Diagnosis of Isolated Congenital Esophageal Stenosis in a Preterm Neonate

A 2-day-old preterm female neonate weighing 1.6 kg and having excessive frothing from mouth was investigated for suspected esophageal atresia and tracheoesophageal fistula. X-ray findings of an unusually low-ending upper pouch (up to T8 level) and the absence of gas in abdomen lead to suspicion of an unusual variety of esophageal atresia. Hence unlike the usual management of pure esophageal atresia, in terms of esophagostomy and gastrostomy in neonatal period, right thoracotomy was performed allowing successful primary anastomosis. A high index of suspicion on the basis of radiological picture led to early diagnosis of a rare anomaly like congenital esophageal stenosis and successful management of this low birth weight baby.

Robotic surgery for lung resections—total port approach: advantages and disadvantages

PubMed Central

Ramadan, Omar I.; Cerfolio, Robert J.

2017-01-01

Minimally invasive thoracic surgery, when compared with open thoracotomy, has been shown to have improved perioperative outcomes as well as comparable long-term survival. Robotic surgery represents a powerful advancement of minimally invasive surgery, with vastly improved visualization and instrument maneuverability, and is increasingly popular for thoracic surgery. However, there remains debate over the best robotic approaches for lung resection, with several different techniques evidenced and described in the literature. We delineate our method for total port approach with four robotic arms and discuss how its advantages outweigh its disadvantages. We conclude that it is preferred to other robotic approaches, such as the robotic assisted approach, due to its enhanced visualization, improved instrument range of motion, and reduced potential for injury.

Regional anaesthesia may reduce the rate of persistent postoperative pain (PPP), a frequent and debilitating condition. This review was originally published in 2012 and updated in 2017. To compare local anaesthetics and regional anaesthesia versus conventional analgesia for the prevention of PPP beyond three months in adults and children undergoing elective surgery. We searched CENTRAL, MEDLINE, and Embase to December 2016 without any language restriction. We used a combination of free text search and controlled vocabulary search. We limited results to randomized controlled trials (RCTs). We updated this search in December 2017, but these results have not yet been incorporated in the review. We conducted a handsearch in reference lists of included studies, review articles and conference abstracts. We searched the PROSPERO systematic review registry for related systematic reviews. We included RCTs comparing local or regional anaesthesia versus conventional analgesia with a pain outcome beyond three months after elective, non-orthopaedic surgery. At least two review authors independently assessed trial quality and extracted data and adverse events. We contacted study authors for additional information. We presented outcomes as pooled odds ratios (OR) with 95% confidence intervals (95% CI), based on random-effects models (inverse variance method). We analysed studies separately by surgical intervention, but pooled outcomes reported at different follow-up intervals. We compared our results to Bayesian and classical (frequentist) models. We investigated heterogeneity. We assessed the quality of evidence with GRADE. In this updated review, we identified 40 new RCTs and seven ongoing studies. In total, we included 63 RCTs in the review, but we were only able to synthesize data on regional anaesthesia for the prevention of PPP beyond three months after surgery from 39 studies, enrolling a total of 3027 participants in our inclusive analysis.Evidence synthesis of seven RCTs favoured epidural anaesthesia for thoracotomy, suggesting the odds of having PPP three to 18 months following an epidural for thoracotomy were 0.52 compared to not having an epidural (OR 0.52 (95% CI 0.32 to 0.84, 499 participants, moderate-quality evidence). Simlarly, evidence synthesis of 18 RCTs favoured regional anaesthesia for the prevention of persistent pain three to 12 months after breast cancer surgery with an OR of 0.43 (95% CI 0.28 to 0.68, 1297 participants, low-quality evidence). Pooling data at three to 8 months after surgery from four RCTs favoured regional anaesthesia after caesarean section with an OR of 0.46, (95% CI 0.28 to 0.78; 551 participants, moderate-quality evidence). Evidence synthesis of three RCTs investigating continuous infusion with local anaesthetic for the prevention of PPP three to 55 months after iliac crest bone graft harvesting (ICBG) was inconclusive (OR 0.20, 95% CI 0.04 to 1.09; 123 participants, low-quality evidence). However, evidence synthesis of two RCTs also favoured the infusion of intravenous local anaesthetics for the prevention of PPP three to six months after breast cancer surgery with an OR of 0.24 (95% CI 0.08 to 0.69, 97 participants, moderate-quality evidence).We did not synthesize evidence for the surgical subgroups of limb amputation, hernia repair, cardiac surgery and laparotomy. We could not pool evidence for adverse effects because the included studies did not examine them systematically, and reported them sparsely. Clinical heterogeneity, attrition and sparse outcome data hampered evidence synthesis. High risk of bias from missing data and lack of blinding across a number of included studies reduced our confidence in the findings. Thus results must be interpreted with caution. We conclude that there is moderate-quality evidence that regional anaesthesia may reduce the risk of developing PPP after three to 18 months after thoracotomy and three to 12 months after caesarean section. There is low-quality evidence that regional anaesthesia may reduce the risk of developing PPP three to 12 months after breast cancer surgery. There is moderate evidence that intravenous infusion of local anaesthetics may reduce the risk of developing PPP three to six months after breast cancer surgery.Our conclusions are considerably weakened by the small size and number of studies, by performance bias, null bias, attrition and missing data. Larger, high-quality studies, including children, are needed. We caution that except for breast surgery, our evidence synthesis is based on only a few small studies. On a cautionary note, we cannot extend our conclusions to other surgical interventions or regional anaesthesia techniques, for example we cannot conclude that paravertebral block reduces the risk of PPP after thoracotomy. There are seven ongoing studies and 12 studies awaiting classification that may change the conclusions of the current review once they are published and incorporated.

A case of an ectopic lobe of the liver connected to a normal diaphragm is described. A 9-year-old, castrated male cat underwent thoracotomy for a pulmonary mass. The removed mass was attached to the diaphragm that histologically was ectopic liver. The ectopic liver had no connection with the main liver. Because the occurrence of ectopic supradiaphragmatic hepatic tissue is a possibility, this should be considered as a differential diagnosis for caudal pulmonary or caudal mediastinal masses in a cat. This report describes, to the authors' knowledge, the first case of ectopic hepatic tissue attached to the diaphragm of a cat. The authors also characterize the asymptomatic clinical presentation and radiographic findings of this cat and suggest further imaging with computed tomography in unusual case presentations.

A case of unilateral nearly total hypoperfusion of the left lung in a 13-month-old girl is presented. The combination of the lung hypoperfusion and accumulation of the Tc-99m MDP and Ga-67 citrate in the same area suggested the preoperative diagnosis of mediastinal neuroblastoma. Explorative thoracotomy revealed the presence of a neuroblastoma compressing the left lung pedicle. The described scintigraphic appearance in the pediatric age group is suggested as typical of mediastinal neuroblastoma. This pathology should be included in the following gamuts in nuclear medicine: unilateral decrease or absent lung perfusion, unilateral diffuse chest uptake of Ga-67 citrate, and unilateral pulmonarymore » uptake in bone scintigraphy.« less

This article reviews the present state of the art of resuscitation of dogs and cats. The purpose of resuscitation is to revive animals so that the vital functions resume together with a normal brain function. Resuscitation must be started as soon as the cardiopulmonary arrest has been confirmed. Adequate ventilation and effective circulation to the most vital body organs, the heart and the brain, have the highest priority. They can be achieved by endotracheal intubation, artificial ventilation with 100% oxygen and rhythmic compression of the closed chest or direct cardiac massage following thoracotomy. Medical therapy is an important part of resuscitation. In the absence of a central venous route, deep endotracheal administration is the preferred method of administration. Most medications can be administered through the endotracheal tube in this fashion.

From full thoracotomy to uniportal video-assisted thoracic surgery: lessons learned

Over the last two decades, conventional video-assisted thoracic surgery (VATS) has established itself as the preferred approach for almost all thoracic surgical procedures. The procedure provides a safe and easy approach with undisputed patient benefit at a cost acceptable to the healthcare system all over the world, in large hospitals as well as underprivileged rural areas. VATS has effectively addressed the patients' right to less scarring, trauma (both of access and intrathoracic manipulation), medication, pain, hospitalization, and early return home and work. These improvements have been further stressed by the introduction of uniportal VATS (uniVATS). Single port surgery is a very exciting new modality in the field of minimal access surgery which aims at further reducing scars of standard vats and towards an hypothetical prospective of scarless surgery.

Hemangioma is the most common primary tumor of the spine. Pregnancy is a risk factor increasing the possibility of disclosure or exacerbation of symptoms of spinal hemangioma. This paper presents a case of 32-year-old woman with hemangioma of Th6 vertebrae, which was revealed by paresis of the lower limbs and sphincters dysfunction at 34 weeks gestation. Pregnancy has ended with a cesarean section. Then posterolateral thoracotomy and removal of hemangioma were performed. Spinal cord was decompressed and stabilization of the spine with metal implants was carried out. Histological examination discovered cavernous hemangioma weaving. The patient is followed up in the outpatient clinic. Despite the improvement of neurological status--enhancement of the sensory function and development of bladder and rectal sphincter automatism--she did not regain the ability to walk alone.

Disruptive technology in the treatment of thoracic trauma.

Smith, R Stephen

2013-12-01

The care of patients with thoracic injuries has undergone monumental change over the past 25 years. Advances in technology have driven improvements in care, with obvious benefits to patients. In many instances, new or "disruptive" technologies have unexpectedly displaced previously established standards for the diagnosis and treatment of these potentially devastating injuries. Examples of disruptive technology include the use of ultrasound technology for the diagnosis of cardiac tamponade and pneumothorax; thoracoscopic techniques instead of thoracotomy, pulmonary tractotomy, and stapled lung resection; endovascular repair of thoracic aortic injury; operative fixation of flail chest; and the enhanced availability of extracorporeal lung support for severe respiratory failure. Surgeons must be prepared to recognize the benefits, and limits, of novel technologies and incorporate these methods into day-to-day treatment protocols. Copyright © 2013 Elsevier Inc.

We reported a case of patent ductus arteriosus (PDA) with congenital anomaly of coronary arteries as abnormal origin of right coronary artery (RCA) and left coronary artery (LCA) from a single ostium of the right coronary sinus. A 21-year-old man referred to our institution for evaluation of cardiac murmur. He has suffered from palpitation and atypical chest pain for three months. On physical examination, a continuous murmur was heard in the second left parasternal space. Transthoracic echocardiography showed normal left and right ventricular size and systolic function (LVEF = 55%). Main pulmonary artery (PA) and left pulmonary artery (LPA) branch were considerably dilated. Considering normal coronary flow, lack of clinical evidence of myocardial ischemia and echocardiography findings, patient underwent surgical closure of PDA via left thoracotomy and after five days discharged uneventfully.

An 88-year-old woman was diagnosed with aortic stenosis and an aortic annulus that was too narrow to perform transcatheter aortic valve implantation. Surgery was performed through a 7-cm right mini-thoracotomy at the fourth intercostal space. A 19-mm aortic valve bioprosthesis was implanted after root enlargement. The fourth intercostal space was a suitable site for aortic root enlargement because of the shorter skin-to-root distance and the detailed exposure of the aortic valve after cutting the aortic wall. This study concluded that minimally-invasive aortic valve replacement following root enlargement can be an option for the treatment of elderly patients with aortic stenosis accompanied by an annulus that is too small to perform transcatheter aortic valve implantation.

Although sensitive human chorionic gonadotropin assays and advances in chemotherapy have assumed primary importance in the management of gestational trophoblastic neoplasia, surgery remains important in the overall care of these patients. Management of molar pregnancies consists of surgical evacuation and subsequent monitoring. Hysterectomy decreases the risk of post-molar trophoblastic disease in appropriate patients and, when incorporated to primary management of gestational trophoblastic neoplasia, can decrease the chemotherapy requirements of patients with low-risk disease. In patients with high-risk disease, surgical intervention is frequently required to control complications of disease or as therapy to stabilize patients during chemotherapy. Hysterectomy, thoracotomy, or other extirpative procedures may be integrated into the management of patients with chemorefractory disease. Interventional procedures are useful adjuncts to control bleeding from metastases.

The bronchial biliary fistula surgery is a major one, always going with a higher rate of complication especially in case of bile duct obstruction. The aim of this study is to find out the contribution of endoscopic sphincterotomy while reporting the results of surgical treatment of bronchial biliary fistulae by exclusive thoracotomy. This was a retrospective study, which took place in the Department of Thoracic Surgery, University Hospital Hassan II, from January 2009 to March 2016. The parameters studied in connection with the bronchial biliary fistula of hydatid origin were: age, sex, origin, history of surgery especially for hepatic hydatid cyst, term of bilyptysie, imaging results, preoperative cholangiography indications, surgical treatment modalities and patients trends. A sample of 12 patients was included (6 men and 6 women) with an average age of 44 years old, with a gap spanning between 17 and 81 years. Seven patients had at least a history of hepatic hydatid surgery. The biliptysie was the main symptom in 8 patients. A biological cholestasis syndrome was found in 6 patients. The thoracoabdominal CT scan performed on all patients comes out with results in 100% of cases. Four patients received endoscopic retrograde cholangiography that allowed them to release the bile duct completely by sphincterotomy with extraction of hydatid membrane in one patient and with development of a biliary stent in another patient. The incision was a low posterolateral thoracotomy in 10 patients that went under surgery. It has allowed to deal in one-time liver and lung injuries combined with diaphragmatic breach repair. Inside the group of patients that went under surgery, the postoperative results were simple in 8 cases. We have noted an overall mortality rate of 18.2%. Bronchial biliary fistula surgery complications remains considerable despite the progress of diagnostic imaging. Preoperative endoscopic sphincterotomy is a milestone in the handling of this surgery. It may even be suggested as exclusive therapy in inoperable patients with significant biliptisy. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

This review aims to answer the most common questions in routine surgical practice during the first 48 h of blunt chest trauma (BCT) management. Two authors identified relevant manuscripts published since January 1994 to January 2014. Using preferred reporting items for systematic reviews and meta-analyses statement, they focused on the surgical management of BCT, excluded both child and vascular injuries and selected 80 studies. Tension pneumothorax should be promptly diagnosed and treated by needle decompression closely followed with chest tube insertion (Grade D). All traumatic pneumothoraces are considered for chest tube insertion. However, observation is possible for selected patients with small unilateral pneumothoraces without respiratory disease or need for positive pressure ventilation (Grade C). Symptomatic traumatic haemothoraces or haemothoraces >500 ml should be treated by chest tube insertion (Grade D). Occult pneumothoraces and occult haemothoraces are managed by observation with daily chest X-rays (Grades B and C). Periprocedural antibiotics are used to prevent chest-tube-related infectious complications (Grade B). No sign of life at the initial assessment and cardiopulmonary resuscitation duration >10 min are considered as contraindications of Emergency Department Thoracotomy (Grade C). Damage Control Thoracotomy is performed for either massive air leakage or refractive shock or ongoing bleeding enhanced by chest tube output >1500 ml initially or >200 ml/h for 3 h (Grade D). In the case of haemodynamically stable patients, early video-assisted thoracic surgery is performed for retained haemothoraces (Grade B). Fixation of flail chest can be considered if mechanical ventilation for 48 h is probably required (Grade B). Fixation of sternal fractures is performed for displaced fractures with overlap or comminution, intractable pain or respiratory insufficiency (Grade D). Lung herniation, traumatic diaphragmatic rupture and pericardial rupture are life-threatening situations requiring prompt diagnosis and surgical advice. (Grades C and D). Tracheobronchial repair is mandatory in cases of tracheal tear >2 cm, oesophageal prolapse, mediastinitis or massive air leakage (Grade C). These evidence-based surgical indications for BCT management should support protocols for chest trauma management. © The Author 2014.

Minimally invasive and video assisted mitral valve surgery has been used widely since beginning of 20 th . Different reduced surgical approaches allowed replacing or repairing a mitral valve sparing sternal incision. Nevertheless the most used strategy has been in the last years the right mini thoracotomy and the extra thoracic cardiopulmonary bypass (CPB). The main goal is avoiding sternal approach for mitral valve procedures and improve postoperative course of the patients. Some postoperative complication likes blood loss, need for transfusion, prolonged intubation and infection has been reduced using this alternative technique. A special advantages has been reported in elderly or high risk patients and in redo cases. Several cardiac centres using videoscopy and a revolutionary set up for CPB management and aortic occlusion have adopted the approach. The team approach, including surgeon, anaesthesiologist, nurse, cardiologist and perfusionist, is crucial for a safe and effective realization of this surgical strategy. The proper use of catheters and Seldinger skilfulness, and the guidance of trans-esophageal echocardiography (TEE) during the procedure are two milestones of this technique. A careful and progressive learning curve is required for all the components of the team. In fact some peculiarity likes modified surgical instruments, 3D and Full HD video assisted view, percutaneous canulation for CPB and myocardial protection, etc., make this procedure challenging for all members of the operative room (OR) team. Our favourite set-up include right mini thoracotomy in the IV intercostal space, femoral vein and arterial canulation and an additional venous cannula in the superior vena cava for the drainage of the upper part of the body. Aortic occlusion is achieved usually using an endo-aortic clamp positioned by means of continuous and careful TEE guidance. A mitral valve procedure is realized by direct or video guided view; using adapted and shaft instruments or special atrial retractors all standard techniques are used in this setting. The literature reports and our published results showed the technique is safe, easy to replicate and allows an excellent rate of valve repair even in more complex patients.

Prognostic information known preoperatively allows stratification of patients to surgery; induction therapy and surgery; or definitive chemoradiotherapy and may prevent a futile thoracotomy. Attention has focussed on the standard uptake value (SUV) of the primary tumour but less has been described regarding the 18F-fluoro-2-deoxy-D-glucose (18F-FDG) avidity of mediastinal nodes. We aimed, in a group of surgically resected cN0-1 but pN2 tumours, to compare the survival of patients with and without 18F-FDG avid mediastinal nodes. Retrospective review of a surgical database identified cN0-1 non-small-cell lung cancer (NSCLC) patients with pN2 disease after resection. Survival of non-FDG avid N2 versus FDG avid N2 groups was compared after stratification according to variables found on univariate analysis to affect survival. From January 1993 to December 2006, 42 patients were identified; 27 (64%) had non-FDG avid N2 disease. Five-year and median survival were better in the non-FDG avid N2 disease group, 25% versus 0% and 30 (16-44) versus 13 (10-16) months, respectively (p=0.02). After 1998, the difference in survival was 41% versus 0% and 35 (14-56) versus 12 (16-18) months, respectively (p=0.02). After resection, patients with non-FDG avid N2 disease have better survival than patients with FDG avid N2 disease. Exploratory thoracotomy alone (after frozen section analysis) cannot be advocated in patients with non-FDG avid N2 disease as survival after resection appears at least equivalent to alternate therapeutic approaches in this group. This assertion may be tempered if right pneumonectomy is required or R0 resection is unachievable. Mediastinal nodal avidity may improve stratification in future studies of long-term survival in NSCLC. Crown Copyright © 2010. Published by Elsevier B.V. All rights reserved.

Utility of blind forceps biopsy of the main carina and upper-lobe carina in patients with non-small cell lung cancer.

2001-02-01

Preoperative detection of non-small cell lung cancer (NSCLC) metastasis to the main carina and upper-lobe carina can alter the operative approach, preclude further staging procedures, and save many patients from thoracotomy. This study assessed whether bronchoscopic forceps biopsy of the normal-appearing main carina and upper-lobe carina (blind biopsy) ipsilateral to the primary NSCLC lesion improved the accuracy of cancer staging and helped guide the management of these patients. A prospective study of 52 patients was carried out at the SSK Süreyyapasa Center for Chest Disease and Cardiothoracic Surgery. Over a 6-month period, we bronchoscopically evaluated 52 consecutive NSCLC patients who were radiologically classified as operable. At least five blind forceps biopsy specimens were obtained from the main carina and/or upper-lobe carina during each patient's initial fiberoptic bronchoscopic examination. Biopsy specimens were collected from the main carina and upper-lobe carina in 51 and 17 patients, respectively. Initially, all patients were staged and evaluated for operability in standard fashion, without histologic assessment of the blind biopsy specimens. We then restaged the disease and reassessed the patients' operability in light of the biopsy findings. Metastasis was histologically diagnosed in seven patients (13.7%) who underwent main carina biopsy and in four patients (23.5%) who underwent upper-lobe carina biopsy. Cancer-positive blind biopsy results changed the status of 25% (6 of 24) of patients from operable to inoperable, and changed the surgical approach in 11.1% (2 of 18) of patients who ultimately did undergo surgery. We found no statistical relationship between metastasis to either carina and tumor type, stage of disease, visibility of the tumor on fiberoptic bronchoscopy, primary tumor location, T status, or N status (p > 0.05). A blind forceps biopsy of the main carina and upper-lobe carina ipsilateral to the lesion site should be done routinely at initial bronchoscopic examination of all radiologically operable patients with suspected lung cancer. This type of screening can save a significant number of NSCLC patients from inappropriate or unnecessary thoracotomy and further staging procedures with their associated morbidity and risk.

Studies reporting on penetrating thoracic trauma in the pediatric population have been limited by small numbers and implied differences with the adult population. Our objectives were to report on a large cohort of pediatric patients presenting with penetrating thoracic trauma and to determine age-related impacts on management and outcome through comparison with an adult cohort. A Level I trauma center registry was queried between 2006 and 2012. All patients presenting with penetrating thoracic trauma were identified. Patient demographics, injury mechanism, injury severity, admission physiology, and outcome were recorded. Patients were compared, and outcomes were analyzed based on age at presentation, with patients 17 years or younger defining our pediatric cohort. A total of 1,423 patients with penetrating thoracic trauma were admitted during the study period. Two hundred twenty patients (15.5%) were pediatric, with 205 being adolescents (13-17 years) and 15 being children (≤ 12 years). In terms of management for the pediatric population, tube thoracostomy alone was needed in 32.7% (72 of 220), whereas operative thoracic exploration was performed in 20.0% (44 of 220). Overall mortality was 13.6% (30 of 220). There was no significant difference between the pediatric and adult population with regard to injury mechanism or severity, need for therapeutic intervention, operative approach, use of emergency department thoracotomy, or outcome. Stepwise logistic regression failed to identify age as a predictor for the need for either therapeutic intervention or mortality between the two age groups as a whole. However, subgroup analysis revealed that being 12 years or younger (odds ratio, 3.84; 95% confidence interval, 1.29-11.4) was an independent predictor of mortality. Management of traumatic penetrating thoracic injuries in terms of the need for therapeutic intervention and operative approach was similar between the adult and pediatric populations. Mortality from penetrating thoracic trauma can be predicted based on injury severity, the use of emergency department thoracotomy, and admission physiology for adolescents and adults. Children may be at increased risk for poor outcome independent of injury severity. Epidemiologic study, level III.

Is thoracoscopic patent ductus arteriosus closure superior to conventional surgery?

2015-10-01

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether thoracoscopic patent ductus arteriosus (PDA) closure is superior to conventional surgery. Altogether 821 papers were found using the reported search, 11 of which represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Eleven studies included in the analysis consisted of two prospective and three retrospective, non-randomized studies and six case series. Four included studies focused only on preterm infants, three studies enrolled neonates and the other four analysed all age groups from neonates to older children or young adults. There were no differences in mortality between video-assisted thoracoscopic surgery (VATS) and conventional surgery. Two studies suggested that VATS offers shorter operative times. Two papers observed shorter hospital stay, although the other two noted no significant difference. A large prospective trial found VATS to be associated with a lower number of postoperative complications in neonates and infants, whereas other studies suggested no significant differences in short-term postoperative complications. There is little evidence to suggest better musculoskeletal status and cosmesis in neonates following VATS. Conversion from thoracoscopy to thoracotomy described in six papers was seldom and it did not lead to any additional complications. All observational studies confirmed that both techniques are free from major adverse cardiovascular complications and these two techniques can be safely used in all patients qualified for surgical PDA closure. Two studies compared cost-effectiveness between the two techniques; one of them described VATS as significantly more cost-efficient, whereas the other study observed no difference. However, it should be noted that data were provided from different countries and time periods. The results presented suggest that there are no significant differences in early clinical outcomes between VATS and thoracotomy in all age groups. However, where differences have been shown, such as pain, postoperative complications, length of hospital and ICU stay and cost, these favour the VATS approach. © The Author 2015.

1999-04-01

In open lung surgery the surgical access is encircled by the ribs, which should result in a high glove perforation rate compared with other surgical specialities. Prospectively the surgeon, first and second assistant and the scrub nurse wore double standard latex gloves during 100 thoracotomies. Parameters recorded were: procedure performed, number of perforations, localization of perforation, the seniority of the surgeon, manoeuvre performed at the moment of perforation, immediate cause of perforation, operation time, performance of rib resection during thoracotomy and time of occurrence of the first three perforations. One thousand, six hundred and seventy-three gloves (902 outer, 771 inner) were tested. In 78 operations perforations occurred. There were 150 outer glove perforations (8.9%, 0-8, mean 1.23), 19 inner glove perforations (1.13%, 0-2, mean 0.19). Cutaneous blood exposure was prevented in 78% of all operations and in 87% of all perforations. The perforation rate for the surgeon, the scrub nurse, the first and the second assistant were 61.2, 40.4, 9.7 and 3.1% of all operations, respectively. Rib resection and a duration of more than 2 h resulted in a significant rise of glove perforation rate (P<0.05). The personal experience of the surgeon and the type of operation did not correlate with glove perforation. The immediate cause leading to perforation was named in only 17 cases (13.7%) and comprised contact with bone (seven), a needle stitch (seven) and a production flaw (three). Leaks were localized mostly on the first finger (18%),second finger, (39%) palm and dorsum of the hand (16%). The average occurrence of all first perforations was 38.7 min (range 3-190) after the beginning of surgery, the second after 63.2 min (range 10-195). Fifty-four first perforations (50.5%) were found during the first 30 min of the operation. The reported perforation rate of 78% lies in the highest range of reported perforation rates in different surgical specialities. Double gloving effectively prevented cutaneous blood exposure and thus should become a routine for the thoracic surgeon to prevent transmission of infectious diseases from the patient to the surgeon.

Transthoracic repair of Morgagni's hernia: a 20-year experience from open to video-assisted approach.

Foramen of Morgagni's hernia is an uncommon congenital diaphragmatic hernia. Repair is mostly performed through laparotomy. We prefer the transthoracic approach, which allows better and safer control during thoracic dissection, although it is considered more painful and related to greater morbidity. In recent years we introduced the transxiphoid hand-assisted videothoracoscopic approach, which combines the advantages of the thoracic route with a mini-invasive procedure facilitated by one hand inside the chest. A retrospective review was performed over a 20-year period (1985-2005). Twenty-two patients who had a foramen of Morgagni's hernia repaired were identified and relevant data were collected. Average age was 57 +/- 10 years and one half of the patients were asymptomatic. Chest roentgenograms, chest computerized tomography, and barium enema were used as diagnostic utilities. Posterolateral thoracotomy was performed in 17 (15 right-sided) patients, whereas in 5 (all right-sided) the defect was repaired by transxiphoid hand-assisted videothoracoscopy. Operative time, pain scored by visual analog scale, hospital stay, and cosmetic results by acceptance score were reviewed for every patient. Hernial sac was present in all cases and contained only omentum (n = 13), omentum plus transverse colon (n = 7), omentum plus transverse colon and small bowel (n = 2). In 6 patients (2 videothoracoscopy) we repaired the large defects with polypropylene mesh. Videothoracoscopy achieved significant good results compared to thoracotomy in operative time (85 +/- 7.9 versus 110 +/- 11.3 min, p < 0.01), 24-h visual analog scale (3.5 +/- 1.1 versus 6.7 +/- 3.9, p < 0.01), hospital stay (2.6 +/- 0.5 versus 6.4 +/- 1.2 days, p < 0.01), and acceptance score (4.3 +/- 0.5 versus 3.1 +/- 0.8, p < 0.05). Postoperative course was always uneventful. Patients were followed for an average period of 58.6 +/- 14.7 and 109.7 +/- 43.5 months, respectively: no recurrences were found in any group. We believe that the transthoracic approach is a safe and effective method for repairing Morgagni's hernia. The videothoracoscopic approach is a promising alternative and it may be facilitated by introducing a hand inside the chest.

Intrathoracic and venous pressure relationships during responses to changes in body position

Avasthey, P.; Wood, E. H.

1974-01-01

Simultaneous end-expiratory pressures, referred to midthoracic level, in the superior and abdominal venae cavae, pericardial space, and right and left heart, were recorded without thoracotomy in three anesthetized dogs during sudden changes from supine to vertical head-up or head-down body positions. Intrathoracic and dependent great vein pressures referred to midchest level (sixth thoracic vertebra) decreased and showed simple hydrostatic gradients in either vertical position. However, a discontinuity in the large vein hydrostatic gradient occurred just distal to the superior margin of the thorax in either body position and was resumed again above this level. It is concluded that, just as the cerebrospinal fluid and intraperitoneal pressures minimize the effects of gravitational and inertial forces on the cerebral and visceral circulations, the pericardial and pleural pressures have a similar role for the heart proper.

Pulmonary embolism from gunshot missiles.

Bernini, C O; Junqueira, A R; Horita, L T; Birolini, D; Branco, P D; de Oliveira, M R

1983-05-01

In patients having missile wounds, the most bizarre trajectories and lodgment sites have been reported. Entry of the missile into the blood stream and subsequent embolization is quite an uncommon event. Isolated reports published in the literature date back to the beginning of the century. This article was undertaken to present two instances of pulmonary embolism due to gunshot missiles. Most investigators agree that the missile should be removed when located in the pulmonary artery and its branches because of the high risk of severe complications, such as pulmonary infarction, secondary thrombosis, infection, erosion of the arterial wall and local hemorrhage. In such instances, a thoracotomy is recommended. The alternative treatment in the instances reported herein, conceived and successfully performed by us, was embolectomy through percutaneous cardiovascular catheterization. As a novel procedure, the method has proved effective and liable to minimal risk.

THE MANAGEMENT OF CHYLOTHORAX

PubMed Central

Connolly, John E.; Smith, John W.

1959-01-01

Chylothorax is readily diagnosed from the characteristic qualities of the effusion. Treatment should initially be conservative, consisting of multiple aspirations followed, if necessary, by suction drainage. Approximately half of the patients will not respond to these measures, and direct ligation and division of the duct is necessary for cure. This operation is most readily carried out through the right chest, the thoracic duct being ligated just above the diaphragm. In cases in which the duct is surrounded by tumor, radiotherapy to the mediastinum is often successful in controlling the reaccumulation of chyle, but irradiation is generally not recommended until after a tissue diagnosis has been made by thoracotomy. Nutritional problems are often concomitants of chylothorax. ImagesFigure 1 (Case 1).Figure 2 (Case 1).Figure 3 (Case 2).Figure 4 (Case 2).Figure 5 (Case 3).Figure 6 (Case 3). PMID:13671361

The story of … a lead.

The totally transvenous implantable defibrillator lead, conceived by Mirowski and Mower 45 years ago, is irrevocably related to the wide acceptance of this therapy. It paved the way for the era for non-thoracotomy implantation. This paper covers the most important details of the evolution--over this 45-year period--of the original (ENDOTAK) transvenous ICD lead and subsequent iterations. Over that time period, there have been over 800 000 patients implanted with this family of leads. The 'story' addresses the multiple problems encountered, technological improvements in materials, design, and testing to overcome them. And, the need for continued close collaboration between physicians and industry focused on reliability and longevity of this critical component of these life-saving systems.

Spontaneous Hemothorax, A Rare Face of Vertebral Osteochondroma.

PubMed

Sainte, Sarah; Decaluwé, Herbert; Vanbrabant, Peter

2017-06-01

Osteochondroma is the most common benign tumor of the bone. It is usually asymptomatic, but complications may result from mechanical injury to adjacent anatomic structures, such as the diaphragm and lung, when located intrathoracically. We report the unusual occurrence of a large hemothorax and lacerated right diaphragm in a 41-year-old woman caused by vertebral osteochondroma affecting the eleventh thoracic vertebra. Thoracoscopic exploration with resection of the osteochondroma and repair of the diaphragm was performed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous hemothorax is a potential life-threatening condition when the initial diagnosis is postponed and hemodynamic instability and hypovolemic shock occurs. Osteochondroma as a cause of spontaneous hemothorax is uncommon but may require urgent surgical intervention with video-assisted thoracoscopic surgery of thoracotomy to control the hemorrhage and prevent recurrence.

Systematic review of published studies on safety and efficacy of thoracoscopic and robot-assisted lobectomy for lung cancer.

PubMed

Nakamura, Hiroshige

2014-01-01

The safety and efficacy of thoracoscopic and robot-assisted lobectomies for primary lung cancer were reviewed in the literature. Thoracoscopic surgery is less invasive compared to thoracotomy, and it has been reported to be superior with regard to the outcome. In addition, the operability of a surgical robot (da Vinci) is favorable and supplements the disadvantages of conventional endoscopic surgery. Robot-assisted lobectomy has been reported to be comparable to thoracoscopic surgery with regard to the safety and efficacy based on analysis of perioperative results and superior with regard to the operability and length of the learning curve. However, a high cost and a long operative time are of concern. Since robot-assisted surgery has been performed only in early cases, the continuation of a comparative investigation may be necessary.

Pulmonary blastoma with diverse mesenchymal proliferation

Chaudhuri, M. Ray; Eastham, W. N.; Fredriksz, P. A.

1972-01-01

Pulmonary blastomas are extremely rare subpleural tumours consisting of relatively well-differentiated branched tubular glands which resemble fetal lung tissue embedded in a malignant mesodermal stroma. The previous 13 established cases reported up to June 1969 are now supplemented by a fourteenth. The patient was a 32-year-old man who developed acute pain in the right chest followed by a haemorrhagic pleural effusion. At thoracotomy a yellowish-white necrotic and vascular tumour was located lying loosely in the fissure between the upper and the middle lobes. The histological appearance of the tumour was unusual in that the mesodermal element was very variable and in different areas simulated fibrosarcoma, leiomyosarcoma, lipomyxosarcoma, and malignant haemangiopericytoma. This diversity of mesodermal proliferation is best explained on the basis that the tumour has originated in an embryonic or pleuripotential type of mesenchyme, the site of which is probably in the periphery of the lung.

Giant mediastinal haemangiopericytoma: an uncommon case.

Agrawal, D; Lahiri, T K; Lakhotia, S; Singh, Deepak

2014-01-01

Haemangiopericytoma is a rare soft tissue tumour characterised by tightly packed tumour cells situated around thin walled endothelial lined vascular channels, ranging from capillary sized vessels to large gaping sinusoidal spaces. The tumour cells are surrounded by reticulin and are negative for muscle, nerve and epithelial markers. The diagnosis of extra-pulmonary intra-thoracic, extra-pleural mediastinal mass is difficult. It constitutes only 6% of all primary tumours and cysts of the mediastinum. We report the rare occurrence of primary intra-thoracic, extra-pulmonary mediastinal haemangiopericytoma of mesenchymal origin with perivascular localisation. The patient underwent right postero-lateral thoracotomy and post-operatively received chemotherapy with adriamycin (60 mg/m2) on day 1 and ifosfamide (1.5 g/m2) on day 1 to 3. Thirty-seven months after the operation, the patient has been well with evidence of a single recurrence in the left lower lobe.

2016-01-01

Endobronchial lipomas are rare benign tumors whose symptoms are usually confused with recurrent infections or even asthma diagnosis, and mostly caused by endobronquial obstructive component which also conditions severity. We report a case of a 60-year-old man with a right-lower lobe upper-segment endobronchial myxoid tumor with uncertain diagnosis. We performed a single incision video-assisted anatomical segmentectomy and wedge bronchoplasty with handsewn closure to achieve complete resection and definitive diagnosis. During the postoperative air leak was not observed and there was no complication, with low pain scores and complete recovery. Final pathological exam showed endobronchial lipoma. Single-incision (SI) anatomical segmentectomies are lung-sparing resections for benign or low-grade malignancies with diagnostic and therapeutic value, and the need for a wedge bronchoplasty is not a necessary indication for conversion to multiport or open thoracotomy.

Background: Importance of repairing a diaphragmatic tear due to a missile injury cannot be overemphasized. Even a small diaphragmatic rent should be repaired because of morbidity and mortality caused by subsequent herniation and strangulation. Methods: Fifty-three cases with diaphragmatic injuries caused by penetrating missiles were studied from January 1997 to January 2007. All the patients were primarily explored either for thoracic or abdominal penetrating trauma; the diaphragmatic injury was an associated incidental intraoperative finding. Thoracotomy was performed in 18 patients, Laprotomy in 33 patients and in two patients combined thorocoabdominal approach was utilised for managing associated visceral injuries. Results: Overall mortality was 37.7%. Mortality was dependent on associated injuries of thoracic and abdominal viscera. Most patients died due to associated injuries and septicaemia. None of the patients had any sequelae of diaphragmatic repair. Conclusion: Immediate repair of diaphragmatic injury is of paramount importance to prevent subsequent complications of herniation and strangulation. PMID:21475506

Benign metastasizing leiomyomas in the lungs: a case study

Benign metastasizing leiomyoma (BML) is a rare disease that occurs in middle-aged women with a history of uterine myomas. The most common location of BML is the lungs. We report the case of a 44-year-old obese woman (BMI 45.5) who underwent surgery to remove uterine leiomyomata and then continued to take a drug containing the hormone estradiol for a period of 15 years. Computed tomography chest examinations revealed multiple size nodules of varying size in both lungs. Videothoracoscopy and right thoracotomy was performed, and a few nodules were enucleated from each lobe of the right lung. Postoperative histopathological examination revealed benign metastasizing leiomyoma staining positive for estrogen and progesterone receptors (ER+, PR+). Because of the hormonally dependent cell proliferation, the previously used hormonal drug was discontinued. Treatment with a gonadotropin-releasing hormone analog was included, yielding radiological stabilization of the lung lesions. PMID:27212984

Traumatic hemothorax is usually associated with obvious organ injuries, such as rib fractures, pulmonary injuries, and other mediastinal injuries. We present a rare case in which a 42-year- old Korean man who fell off of a roof, approximately 3 meters in height, resulting in a life-threatening hemothorax without obvious injuries to the thoracic organs. Chest CT showed a large amount of hemothorax in the right side of the thoracic cavity, and an active bleeding, presumably from the posterior intercostal or the phrenic artery, with a focal aneurysmal change. The emergency thoracotomy was performed to bring the active bleeding under control. The operative findings showed there were only the inferior pulmonary ligament tears, and the active bleeding from it. The postoperative course was uneventful and the patient was discharged without any complications. We should consider the inferior pulmonary ligamental injury as one of causes for traumatic hemothorax.

Esophageal duplication cysts are rare congenital abnormalities of the foregut and may be associated with other conditions. Association of esophageal duplication with Gastro-Esophageal Reflux Disease (GERD) has not been reported in children. We are reporting a case of a 16 months baby who had antenatal diagnosis of diaphragmatic hernia. Postnatal CTchest, however, suggested a distal esophageal duplication cyst and a contrast esophagogram showed grade-IV GER. A thoracoscopy in another hospital excluded esophageal duplication at that time. Later, he presented with hematemesis in our department and was re-evaluated. Repeat CTconfirmed a persistent 2.5 x 1.3 cm cyst in distal esophagus. Upper GI endoscopy suggested grade-II esophagitis with a wide patent gastro-esophageal junction. The child was treated with left thoracotomy, excision of the duplication cyst and thoracic fundoplication. He had an uneventful post-operative recovery and is doing well at 6 months follow-up.

Cancer of the hypopharynx and cervical esophagus involve problems such as removal of the cervical region, resection of the esophagus and also esophageal reconstruction. A standard surgical procedure has not been established. In our clinic, surgery is performed by two teams; one for head and neck and the other for the digestive tract. Since 1963, we have performed 22 operations on patients with such cancers; resection of the cancer and reconstruction of the alimentary tract were performed in sixteen 16 patients and palliative operations in six. As procedures of reconstructive surgery, antesternal pharyngogastrostomy was performed in ten patients, and antesternal esophagogastrostomy in one. Six of these reconstructions were carried out with oral insertion of a stapler. In this paper, we present the surgical techniques and some of the problems involved in total esophagectomy without thoracotomy, i.e., blunt dissection of the esophagus and antesternal pharyngogastrostomy, particularly pharyngogastrostomy, using a stapler inserted orally.

Diseases causing blood accumulation in the pleural space (or haemothorax) are usually very demanding for diagnosis and require a multidisciplinar therapeutical approach in emergency. So, their treatment should always be immediate and should aim to restore the optimal patient's haemodynamic conditions and to find the site of bleeding. Chylothorax, a lymphatic effusion in the pleural space, is also a very important pathology, as it effects the nutritional and immunological state of the patient causing pleural involvement and respiratory insufficiency. Stabilisation of vital parameters with adequate systemic therapies (blood perfusions, fluids and pro-coagulation factors, TPN) preceeds surgery, which can be the placement of a thoracic drain or emergency thorascopy and/or thoracotomy. The Authors report the casistic of the latest three years for diagnosis and treatment of haemothorax and chylothorax stressing the advantages of a minimal invasive approach for evacuation and identification of the origin of bleeding and haemorrhage and/or lymphatic effusion control.

Effect of gravitational and inertial forces on vertical distribution of pulmonary blood flow

Chevalier, P. A.; Reed, J. H., Jr.; Vandenberg, R. A.; Wood, E. H.

1978-01-01

Vertical distribution of pulmonary blood flow (VDPBF) was studied, using radioactive microsphere emboli, in dogs without thoracotomy in the right decubitus position during exposure to lateral accelerations of 1, 2, 4, and 6 G. At all levels of force environment studied, an inverse linear relationship was observed between vertical height in the thorax and pulmonary blood flow (ml/min/ml lung tissue) with a decrease in flow to the most dependent region of the lung despite large increases in intravascular pressures at this site. Changes in blood flow were smallest at the mid-lung level, the hydrostatic 'balance point' for vascular and pleural pressures. These force environment-dependent changes in VDPBF are not readily explainable by the Starling resistor analog. Gravity-dependent regional differences in pleural and associated interstitial pressures, plus possible changes in vascular tone resulting from inadequate aeration of blood in the most dependent regions of the lung, probably also affect VDPBF.

Abscess of the residual lobe after lobectomy is a rare but potentially lethal complication. Between January 1975 and December 2006, 1,460 patients underwent elective pulmonary lobectomy for non-small-cell lung cancer at our institution. Abscess of the residual lung parenchyma occurred in 5 (0.3%) cases (4 bilobectomies and 1 lobectomy). Postoperative chest radiography showed incomplete expansion and consolidation of residual lung parenchyma. Flexible bronchoscopy revealed persistent bronchial occlusion from purulent secretions and/or bronchial collapse. Computed tomography in 3 patients demonstrated lung abscess foci. Surgical treatment included completion right pneumonectomy in 3 patients and a middle lobectomy in one. Complications after repeat thoracotomy comprised contralateral pneumonia and sepsis in 1 patient. Residual lobar abscess after lobectomy should be suspected in patients presenting with fever, leukocytosis, bronchial obstruction and lung consolidation despite antibiotic therapy, physiotherapy and bronchoscopy. Computed tomography is mandatory for early diagnosis. Surgical resection of the affected lobe is recommended.

Vertebral haemangiomas are benign lesions and often asymptomatic. They are more common in the thoracic spine where they may become symptomatic with varying presentations. We present two teenage girls who presented with progressive, nontraumatic paraparesis with no background history of chronic cough or underlying medical illness. The radiologic investigations were suggestive of vertebral haemangiomas of the thoracic spine. They had surgery: transthoracic approach with corpectomy and fusion with iliac crest autograft. The posterior stabilisation in the first patient was with Rush nails and circlage wire and only circlage wire in the second patient. The first patient's post-operative recovery was complicated by graft extrusion necessitating re-opening thoracotomy and graft replacement. They are, however, both ambulant at discharge and have remained so 13 and 15 months post-surgery. We have presented two cases with rewarding outcomes in the face of 'adaptive' instrumentation due to limited resources.

Video-assisted thoracic surgery repair of subclavian artery injury following central venous catheterization: a new approach

OBJECTIVES Iatrogenic subclavian artery puncture following central venous catheterization is a rare but potentially fatal complication. There are very few reports in the literature on this condition. We propose the use of video-assisted thoracic surgery (VATS) in the management of these injuries. METHODS The technique of VATS to manage subclavian artery injury was described. We presented the first reported case of successful repair of subclavian artery injury using VATS. RESULTS Using a two-incisional approach for VATS, the haemothorax was rapidly evacuated and the subclavian artery injury was successfully repaired using pledgetted sutures under direct thoracoscopic visualization. The patient had an uneventful postoperative recovery. CONCLUSIONS VATS can be successfully applied to repair subclavian artery injury. The advantages include rapid intrathoracic access, excellent thoracoscopic visualization of the thoracic inlet, and avoidance of the morbidity associated with open thoracotomy. PMID:23518293

Novel avulsion pattern of the left principal bronchus with involvement of the carina and caudal thoracic trachea in a cat.

Schmierer, Philipp A; Schwarz, Andrea; Bass, Danielle A; Knell, Sebastian Christoph

2014-08-01

A 2-year-old, 4.5 kg, neutered male domestic shorthair cat was presented to the emergency service with dyspnoea, anorexia and apathetic behaviour. Thoracic radiographs showed typical signs for a thoracic trauma and a tracheal lesion in the region of the carina, consistent with pseudoairway formation. Computed tomography (CT) was performed in the conscious cat to avoid aggravation of air leakage associated with ventilation. The additional CT findings were consistent with a novel pattern of a traumatic avulsion of the left principal bronchus expanding into the carina and caudal thoracic trachea. Despite the complex avulsion pattern, successful treatment was achieved surgically by performing an end-to-end anastomosis via a fifth right intercostal lateral thoracotomy. The cat was ventilated with a feeding tube and jet ventilation throughout. The cat showed excellent recovery 6 months after surgery. © ISFM and AAFP 2013.

A 13-year-old girl, who did not receive any treatment for few hours following Road Traffic Injury (RTI), reported to the Casualty Department and found to have patent airway with clinically normal C spine, air-hunger (RR 42/minute), trachea deviated to left, distended neck veins and absent breath sounds on the right side. The chest X-ray she carried, done immediately after the injury, showed right sided tension pneumothorax. She was put on oxygen at 11 L/minute and an Intercostal chest tube drainage (ICD) was inserted on right side. Her oxygen saturation (40%) failed to improve. ICD bag showed continuous bubbling and air entry remained absent on the right side. An urgent right thoracotomy was done which revealed right main bronchus tear; the tear was repaired using interrupted Prolene ® sutures. Patient recovered well and was discharged 10 days later in a stable condition.

1999-03-01

A 4-mo-old female white lion (Panthera leo) cub was presented with a 2-wk history of persistent postprandial regurgitation, mild dyspnea, and poor weight gain. The cub was weak and thin but otherwise alert. Survey and contrast radiography revealed a large dilated esophagus cranial to the heart base, with an esophageal filling defect present at the level of the fourth thoracic vertebra. A vascular ring anomaly was tentatively diagnosed. Exploratory thoracotomy revealed a double aortic arch and a persistent left vena cava. The left aortic arch was ligated and divided, and recovery was uneventful. A single episode of regurgitation occurred within the first postoperative month, and the cub gained 5.5 kg in weight during the same time period. Neither double aortic arch nor persistent left vena cava has been reported in a nondomestic felid.

To define the risk factors of complications which are followed by re-operations in patients with cardiac and pericardial wounds and to prevent these complications. Retrospective and prospective analysis of 1072 victims with cardiac and pericardial injuries for 35 years was performed. Overall mortality was 17.2%. 98 patients died during surgery. Postoperative bleeding was observed in 38 (3.9%) cases. In 28 cases re-operations were performed for bleeding-related complications. Indications for re-thoracotomy were one-time drainage from pleural cavity over 500 ml or bleeding rate over 100 ml per hour for 4 hours. Prevention of postoperative bleeding in case of cardiac and pericardial wounds was developed on basis of analysis of these observations. Risk factors of complications requiring re-operation are cardiomyopathy of different etiology, technical and tactical errors during primary intervention and hypocoagulation with massive blood loss. Prevention of these complications includes careful heart wound closure, comprehensive intraoperative control, correction of hemostatic system.

In lung cancer patients where a malignant pleural effusion is found at operation could resection ever still be justified?

PubMed

Fiorelli, Alfonso; Santini, Mario

2013-08-01

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether surgery could ever be justified in non-small cell lung cancer patients with an unexpected malignant pleural effusion at surgery. Eight papers were chosen to answer the question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated. Study limitations included a lack of retrospective studies, the heterogeneous patient population and various treatments applied. Three papers found that surgery--compared to exploratory thoracotomy--was associated with a survival advantage in cases of minimal pleural disease. One paper showed that the median survival time of 58.8 months in patients with pleural effusion was better than that of patients with more extensive pleural dissemination as pleural nodule (10 months; P=0.0001) or pleural nodule with effusion (19.3 months; P=0.019). Another study showed that pleural effusion patients with N0-1 status had a median survival time more than 5 years longer than patients with similar or more extensive pleural dissemination but with N2-N3 status. A further study showed a better 5-year survival time in patients with pleural effusion, than in patients with pleural nodule (22.9% vs 8.9%, respectively; P=0.45). In two papers, surgery vs exploratory thoracotomy had better survival in cases of N0 status and of complete tumour resection independently of pleural dissemination. Different strategies were employed to obtain freedom from macroscopic residual tumour, including pneumonectomy, lobar resection or, to a lesser extent, pleurectomy in patients having pleural dissemination. Only one paper reported a worse median survival time after pneumonectomy than for more limited resections (12.8 vs 24.1 months, respectively; P=0.0018). In the remaining papers, no comparison between the different resections was made. In all studies except one, surgery was a component of multimodal treatment. Intrapleural chemotherapy was largely applied with systemic adjuvant chemotherapy and/or radiotherapy. The study period and/or year of publication of most papers was 10 years or more, this may explain the different chemotherapy regimens used in the various studies. No current guidelines support surgery over conservative therapy and the identified studies in this review are not strong enough to change this recommendation.

The aim was to investigate whether 2 weeks of inspiratory muscle training (IMT) could preserve respiratory muscle strength in high-risk patients referred for pulmonary resection on the suspicion of or confirmed lung cancer. Secondarily, we investigated the effect of the intervention on the incidence of postoperative pulmonary complications. The study was a single-centre, parallel-group, randomized trial with assessor blinding and intention-to-treat analysis. The intervention group (IG, n = 34) underwent 2 weeks of postoperative IMT twice daily with 2 × 30 breaths on a target intensity of 30% of maximal inspiratory pressure, in addition to standard postoperative physiotherapy. Standard physiotherapy in the control group (CG, n = 34) consisted of breathing exercises, coughing techniques and early mobilization. We measured respiratory muscle strength (maximal inspiratory/expiratory pressure, MIP/MEP), functional performance (6-min walk test), spirometry and peripheral oxygen saturation (SpO2), assessed the day before surgery and again 3-5 days and 2 weeks postoperatively. Postoperative pulmonary complications were evaluated 2 weeks after surgery. The mean age was 70 ± 8 years and 57.5% were males. Thoracotomy was performed in 48.5% (n = 33) of cases. No effect of the intervention was found regarding MIP, MEP, lung volumes or functional performance at any time point. The overall incidence of pneumonia was 13% (n = 9), with no significant difference between groups [IG 6% (n = 2), CG 21% (n = 7), P = 0.14]. An improved SpO2 was found in the IG on the third and fourth postoperative days (Day 3: IG 93.8 ± 3.4 vs CG 91.9 ± 4.1%, P = 0.058; Day 4: IG 93.5 ± 3.5 vs CG 91 ± 3.9%, P = 0.02). We found no association between surgical procedure (thoracotomy versus thoracoscopy) and respiratory muscle strength, which was recovered in both groups 2 weeks after surgery. Two weeks of additional postoperative IMT, compared with standard physiotherapy alone, did not preserve respiratory muscle strength but improved oxygenation in high-risk patients after lung cancer surgery. Respiratory muscle strength recovered in both groups 2 weeks after surgery. NCT01793155. © The Author 2015.

Psychological distress associated with cancer treatment is an emerging issue in the management of cancer patients. The aim of this study was to identify the prevalence of postoperative anxiety and depression after surgical treatment for lung cancer, and to assess the risk factors associated with these phenomena. Patients who underwent curative surgical resection for primary lung cancer were included in this study. Patients with complex treatment histories (recurrent or metastatic lung cancer or neoadjuvant treatment) and those taking psychiatric medication were excluded. We prospectively evaluated the degrees of pre- and postoperative anxiety and depression using a Hospital Anxiety Depression Scale questionnaire. The relationships between clinical and patient factors and anxiety and depression after surgical treatment for lung cancer were assessed. A total of 278 patients were enrolled. The mean age was 62 years. Thoracoscopic resection was performed in 246 patients (89%). The prevalence rates of preoperative anxiety and depression were 8% (n = 22) and 12% (n = 32), and changed to 9% (n = 26) and 19% (n = 54) postoperatively (P = 0.37 and <0.001, respectively). Gender, age, marital status, advanced clinical stage, alcohol abuse, smoking status, length of hospital stay, pulmonary function and preoperative comorbidities were not associated with postoperative anxiety and depression. Multivariate analysis revealed that thoracotomy was a risk factor for postoperative anxiety after adjusting for preoperative anxiety (odds ratio [OR] = 4.5, P = 0.002). Thoracotomy (OR = 3.4, P = 0.009), postoperative dyspnoea (OR = 4.8, P < 0.001), severe pain (OR = 3.9, P = 0.001) and diabetes mellitus (OR = 3.0, P = 0.012) were identified as risk factors for postoperative depression after adjusting for preoperative depression. Twenty-four patients were referred to mental health professionals and provided with supportive psychotherapy or pharmacological intervention. Of these, 14 patients (56%) were diagnosed with an adjustment disorder. Postoperative psychological distress and, in particular, depression increased after surgical treatment for lung cancer. Postoperative anxiety and depression were aggravated by residual symptoms after surgery. Careful psychological evaluation and appropriate management are required to improve patients' quality of life after lung cancer surgery. © The Author 2015.

Injuries to the gastroesophageal (GE) junction are infrequently encountered because of the high mortality of associated injuries. Consequently, there is a paucity of literature on the patient demographics and treatment options. The aim of this study was to examine the epidemiology, surgical management, and outcomes of these rare injuries. Patients presenting to LAC + USC Medical Center (January 2008 to August 2016) with traumatic esophageal or gastric injury (DRG International Classification of Diseases-9th Rev.-Clinical Modification and 10th Rev. codes) were extracted from the trauma registry. Patient charts were reviewed, and all patients who sustained an injury to the GE junction were enrolled. Patient demographics, injury characteristics, procedures, and outcomes were analyzed. Of the 238 patients who sustained an injury to the esophagus or stomach during the study period, 28 (12%) were found to have a GE junction injury. Mean age was 26 years (range, 14-57 years), 89% male. Mechanism of injury was penetrating in 96% (n = 27), the majority of which were gunshot wounds (n = 22, 81%). Most patients (n = 18, 64%) were taken directly to the operating room. Ten (36%) underwent computed tomography scan before going to the operating room, all demonstrating a GE junction injury. All patients underwent repair via laparotomy. One (4%) also required thoracotomy to facilitate delayed reconstruction. GE junction injuries were typically managed with primary repair (n = 22, 79%). Associated injuries were frequent (n = 26, 93%), and injury severity was high (mean Injury Severity Score, 25 [9-75]). Mortality was 25% (n = 7), and all patients required intensive care unit admission. Most did not require total parenteral nutrition (n = 25, 89%) or a surgically placed feeding tube (n = 26, 93%). Of the 13 patients who presented for clinical follow-up, all but one (n = 12, 92%) were eating independently by the first clinic visit. GE junction injuries are uncommon and occur almost exclusively after penetrating trauma. Patients are severely injured with a high mortality rate and frequently have associated intracavitary injuries. Most can be fixed through the abdomen alone and do not require thoracotomy for repair. Despite the severity of injuries, the majority of survivors are eating independently by the first clinic visit. Epidemiological, level V.

Pneumonectomy is a proven treatment for lung diseases. We sought to present a comparison between video-assisted thoracic surgery pneumonectomy (VATS-P) and conventional thoracotomy pneumonectomy (CP) on perioperative outcomes and short-term measures of convalescence. A retrospective cohort study was performed to assess perioperative outcomes among patients underwent VATS-P and CP. A total of 32 patients undergoing VATS-P were matched 2:1 about comorbidity, surgical indication, tumour size and lesion location to a previous cohort of 64 patients who underwent CP. Demographic and perioperative data were obtained. Statistical analysis was performed. Mean patient age was 55.4 years for both groups, with equal sex distribution. Pneumonectomy for malignant and benign lesion patients was evaluated individually. For malignant tumour patients, median tumour size was 3.9 cm for both groups. There was no difference between VATS-P and CP cases in transfusion rates (2% vs. 10%, P=0.50), dissected lymph node numbers (11.9 vs. 14.2, P=0.26), dissected lymph node stations (5.0 vs. 4.9, P=0.75), estimated blood loss (226.0 vs. 261.3 mL, P=0.40), complication rate (20.0% vs. 22.5%, P=0.82), postoperative drainage time (5.9 vs. 6.2, P=0.50) or length of hospital stay (7.5 vs. 8.1, P=0.50). Operation time in VATS-P was higher than conventional groups (187.5 vs. 146.3 min, P=0.00) but the mean pain score was significantly less. For benign patients, over 1,000 mL blood losing (1,033.3 vs. 1,233.3 mL, P=0.78) and 180 minutes (186.6 vs. 105.8, P=0.73) OR time was found in both groups. The Length of stay (7.6 vs. 6.3 d, P=0.57), transfusion rates (66.7% vs. 33.3%), complications rates (zero in both group) and length of drainage (6.7 vs. 6.7 d, P=1.0) between two groups are identical. Complete video-assisted thoracic surgery (VATS) pneumonectomy is feasible and safe technique and can be recommended as a surgical treatment for lung cancer patients. However, long-term benefits need to be evaluated by further studies and large sample tests.

A 58-year-old woman was admitted with acute heart failure. She had a long history of resistant hypertension, with an unremarkable work up for secondary causes in the past. Her brachial blood pressure was 210/70 mm Hg, with ankle blood pressure of 100/70 mm Hg. CT angiogram revealed marked narrowing of the descending thoracic aorta between the left subclavian artery and the diaphragm, consistent with middle aortic syndrome (MAS). She was initially managed with diuretics and antihypertensives. Subsequently thoracotomy revealed a severely hypoplastic segment of the descending aorta. The diseased segment was resected and aortic reconstruction performed. Histopathology showed fragmentation of the medial elastic fibres and fibrosis of the medial and intimal layers. These findings along with gross aortic hypoplasia and absence of features of Takayasu's arteritis, suggest that our patient had congenital MAS. The patient has done well since her surgery. We believe this is the first case of congenital MAS reported in the sixth decade of life. 2016 BMJ Publishing Group Ltd.

Improving Operating Room Efficiency via Reduction and Standardization of Video-Assisted Thoracoscopic Surgery Instrumentation.

Friend, Tynan H; Paula, Ashley; Klemm, Jason; Rosa, Mark; Levine, Wilton

2018-05-28

Being the economic powerhouses of most large medical centers, operating rooms (ORs) require the highest levels of teamwork, communication, and efficiency in order to optimize patient safety and reduce hospital waste. A major component of OR waste comes from unused surgical instrumentation; instruments that are frequently prepared for procedures but are never touched by the surgical team still require a full reprocessing cycle at the conclusion of the case. Based on our own previous successes in the perioperative domain, in this work we detail an initiative that reduces surgical instrumentation waste of video-assisted thoracoscopic surgery (VATS) procedures by placing thoracotomy conversion instrumentation in a standby location and designing a specific instrument kit to be used solely for VATS cases. Our estimates suggest that this initiative will reduce at least 91,800 pounds of unnecessary surgical instrumentation from cycling through our ORs and reprocessing department annually, resulting in increased OR team communication without sacrificing the highest standard of patient safety.

Despite the lethality of injuries to the heart, optimizing factors that impact mortality for victims that do survive to reach the hospital is critical. From 2003 to 2012, prehospital data, injury characteristics, and clinical patient factors were analyzed for victims with penetrating cardiac injuries (PCIs) at an urban, level I trauma center. Over the 10-year study, 80 PCI patients survived to reach the hospital. Of the 21 factors analyzed, prehospital cardiopulmonary resuscitation (odds ratio [OR] = 30), scene time greater than 10 minutes (OR = 58), resuscitative thoracotomy (OR = 19), and massive left hemothorax (OR = 15) had the greatest impact on mortality. Cardiac tamponade physiology demonstrated a "protective" effect for survivors to the hospital (OR = .08). Trauma surgeons can improve mortality after PCI by minimizing time to the operating room for early control of hemorrhage. In PCI patients, tamponade may provide a physiologic advantage (lower mortality) compared to exsanguination. Copyright © 2016 Elsevier Inc. All rights reserved.

A 56-years-old woman was referred to our unit for partially treated acromegaly. She had a high level of insulin growth factor. She did not complain of any pulmonary symptoms and was a non-smoker. Physical examination revealed clinical features of acromegaly. She had a 13 mm pituitary adenoma and was proposed for surgical intervention. Her chest X-ray showed a right paracardiac tumor. Computed tomography scan revealed a large right-sided fowler tumor. Pituitary surgery was cancelled and lobectomy after biopsy with lymph nodes excision was performed through thoracotomy. Histological study of the tumor revealed a medium differentiated epidermoid carcinoma with positive lymph nodes and extension to pleura. She was referred to chemotherapy protocol. Association between carcinoma and acromegaly has previously been reported. Most common tumors are colorectal and thyroid neoplasia. As we see in this case report, we need to consider other carcinomas in acromegalic patients like pulmonary carcinoma, despite their rarity in women. PMID:22891085

Dr. Diego Gonzalez Rivas’ trip to the Philippines in November 2015

PubMed Central

2016-01-01

Video-assisted thoracoscopic surgery (VATS) was introduced in the Philippines in 1992. Initially, multiport VATS was utilized for lung resections in 2012. In 2015, after attending a couple of Asian uniportal VATS workshops, where one of the lecturers/surgeons was Dr. Diego Gonzalez-Rivas, Filipino surgeons were able to do uniportal VATS for a lobectomy in 2015. In November 2015, Dr. Rivas went to the Philippines to give lectures and conduct a VATS pre-congress workshop during the 25th Clinical Congress of the Association of Thoracic and Cardiovascular Surgeons of Asia (ATCSA). He then went to the Lung Center of the Philippines (LCP) where he delivered a lecture and performed a uniportal VATS lobectomy on a 64-year-old male patient who had Adenocarcinoma of the left lower lobe. Anesthetic and surgical techniques are described. Uniportal VATS is a safe procedure and oncologic results are comparable with resections done using open thoracotomy. The patients’ quality of life is better because of significantly less pain after the procedure. PMID:29078509

Over the last years the ingestion of disk batteries has become frequent in children with serious consequences. The severity of injuries is related to the growing use of new lithium batteries that may cause catastrophic damages when lodged in the oesophagus. The notes of three consecutive children with lithium batteries lodged in the oesophagus, admitted to our Institute from 2010 to 2014, were reviewed. Clinical presentation, management, and outcome were considered. The first child, a 22-month-old girl, died of a sudden exsanguination due to an aorto-oesophageal fistula. The second case, a 5-year-old boy, had an exploratory thoracotomy to exclude aortic lesion before battery removal, and a spontaneous oesophageal perforation. The third child, a 18-month-old boy, fully recovered after suffering ulcerative oesophageal burns. Lithium battery lodged in the oesophagus is a paediatric emergency requiring a multidisciplinary approach that can be implemented in a tertiary children's hospital.

A newborn female was transferred to our hospital presenting with severe respiratory distress. She underwent tracheal intubation and nasogastric tubing. Investigations revealed a congenital extrahepatic portosystemic shunt (CEPS) type 1, biliary atresia, heterotaxia, polysplenia, malrotation and a double aortic arch (DAA). She underwent the Kasai portoenterostomy and the Ladd procedure when she was 29 days old. On postoperative day 20, she developed sudden hematemesis with bright red blood. Endoscopy showed massive bleeding from an esophageal ulcer, and endoscopic therapy was performed successfully. During left thoracotomy, an aortoesophageal fistula (AEF) was detected and repaired by direct suturing. The postoperative course was uneventful. CEPS type 1 is commonly associated with other congenital malformations; however, there have been no previous reports of an association between CEPS and DAA. Nasogastric tube insertion in a patient with DAA can result in catastrophic AEF. The treatment strategy should be carefully considered in patients with CEPS type 1 and multiple congenital fetal anomalies.

From January 1983 to December 1989, we performed esophagojejunostomy on 379 patients who underwent total gastrectomy for gastric cancer. A mechanical EEA stapler or conventional manual suturing was used. The clinical outcomes of 199 patients in whom stapling was used (stapler group) and 180 patients in whom manual suturing was done (manual group) were compared. Two of the 199 patients in the stapler group and 3 of the 180 patients in the manual group died of causes directly related to the anastomosis. In the stapler group, 16 stapled anastomoses were formed supradiaphragmatically, and manual suturing was done for 6 patients. The highly placed anastomosis was formed without left thoracotomy or with median sternotomy in 8 of the 16 patients in whom the stapling device was used and in 1 of the 6 patients in whom manual suturing was used. The incidence of anastomotic leakage and stenosis did not differ between the groups. Thus, the mechanical stapler facilitated the construction of a rapid, reliable esophagojejunostomic anastomosis.

Minimally invasive techniques are becoming increasingly popular in thoracic surgery. Although median sternotomy is the traditional approach for thymectomy, video-assisted thoracoscopic surgery (VATS) approaches now predominate. This study reports a case series of the novel uniportal subxiphoid-VATS approach to extended thymectomy. Over the period of study (October 2014-January 2017) 17 patients underwent uniportal subxiphoid-VATS extended thymectomy for a thymic nodule at the Shanghai Pulmonary Centre. Ten patients were female, and the mean age of the cohort was 55 years. The mean size of nodule was 23.6 mm. The mean operative duration was 2.5 hours, with one conversion to thoracotomy for bleeding. The mean operative blood loss was 115 mL. The median length of hospital stay was 4 days. There were no episodes of phrenic nerve palsies. The 30-day survival was 100%. Uniportal subxiphoid-VATS is a feasible and safe surgical approach to extended thymectomy in selected patients, with good post-operative outcomes.

Lung suppurative diseases in children are usually responsive to medical treatment or percutaneous drainage. Rarely, pulmonary resection is required for lung abscess in childhood, particularly in presence of co-morbidities. In these cases, a lobectomy is usually performed through an open thoracotomy, with a reported incidence of bronco-pleural fistula up to 9.1% of pediatric series. This consequence is mainly due to the inflammatory condition; however the lack of knowledge of pediatric and thoracic surgeons with this rare condition in childhood can also play a role. In adults with lung cancer, the buttressing of bronchial stump with the additional support of an intercostal muscle (ICM) flap has proved to prevent this complication, as well as to reduce post-operative pain. We report the first pediatric experience of ICM flap used in 2 immunocompetent children requiring lobectomy for suppurative lung conditions. Our preliminary experience confirms the feasibility of protecting the bronchial stump after lobectomy in children, especially in conditions at risk for bronco-pleural fistula development.

Orthotopic implantation of cancer allows metastasis to occur. The most patient-like metastatic orthotopic models are developed with surgical orthotopic implantation using intact tissue in order to preserve the natural tissue structure of the tumor which contains both cancer cells and stroma. In the present study, we performed a simple thoracotomy by making an intercostal incision between the fourth and fifth ribs on the left side of the chest of nude mice. Lung tumor fragments expressing red fluorescent protein were then implanted on the left lung. It was possible to monitor tumor formation in the lung non-invasively by spectral imaging using the Maestro system with a liquid tunable filter. The model described here has high tumorigenicity in the lung (100%) and a low mortality rate (5%). This imageable nude mouse model using surgical orthotopic implantation of lung cancer will be useful for all types of longitudinal studies.

The association of a right aortic arch with an ipsilateral patent ductus arteriosus is rare, especially when there are no other intracardiac anomalies. We report three female patients aged 26, 35 and 9 years with this combination in whom previous attempts at surgical closure by thoracotomy and sternotomy were unsuccessful and who subsequently underwent successful percutaneous closure of the defects using Amplatzer devices. In two patients, although angiography demonstrated the presence of type-A patent ductus arteriosus, it was not possible to determine the minimum diameter accurately and it was necessary to measure it using a sizing balloon. An Amplatzer duct occluder was used in two patients and an Amplatzer muscular ventricular septal defect occluder, in the other. In all patients, full closure was confirmed in the catheterization laboratory and the patients were discharged on the same day with no complications. Percutaneous closure of a right patent ductus arteriosus associated with a right aortic arch is feasible, safe and effective.

Bronchial blood flow was determined in five adult anaesthetised sheep by the video dilution technique. This is a new fluoroscopic technique for measuring blood flow that requires only arterial catheterisation. Catheters were placed into the broncho-oesophageal artery and ascending aorta from the femoral arteries for contrast injections and subsequent videotape recording. The technique yields bronchial blood flow as a percentage of cardiac output. The average bronchial artery blood flow was 0.6% (SD 0.20%) of cardiac output. In one sheep histamine (90 micrograms) injected directly into the bronchial artery increased bronchial blood flow by a factor of 6 and histamine (90 micrograms) plus methacholine (4.5 micrograms) augmented flow by a factor of 7.5 while leaving cardiac output unchanged. This study confirms the high degree of reactivity of the bronchial circulation and demonstrates the feasibility of using the video dilution technique to investigate the determinants of total bronchial artery blood flow in a stable animal model avoiding thoracotomy.

Pectoral implantation of transvenous non-thoracotomy internal cardioverter defibrillators (ICD) has resulted in very few complications whether placed subpectorally or subcutaneously. We report the case of a 68 year old man with a subpectorally implanted MINI-plus (Cardiac Pacemakers, Incorporated, St. Paul, Mn.) transvenous ICD who developed nearly instantaneous severe ipsilateral shoulder pain and immobilization. The symptoms progressed despite aggressive physical therapy. We elected to remove the device from the pectoral site and place it in a traditional abdominal position due to the severity, duration and refractoriness of his symptoms. This procedure utilized the chronic Endotak DSP (Model 0125, Cardiac Pacemakers, Incorporated) transvenous lead, a compatible Endotak DSP lead extender (Model 6952, Cardiac Pacemakers, Incorporated) and the above described ICD. Immediate relief of symptoms was accomplished by relocation of the device to an abdominal site. This intervention should be reserved for patients with severely debilitating symptoms. Prospective comparison of subpectoral and subcutaneous surgical approaches with respect to patient comfort and acceptance and complications may be warranted.

Can Sericin Prove Useful as a Pleurodesis Agent or Tissue Glue?

Background  Sericin is a natural, gum-like, macromolecule protein, synthesized from silkworms for the formation of cocoon shells. The aim of the present study is to describe the effects of sericin when used for pleurodesis and/or as tissue glue. Methods  Adult, male, 12-week-old Wistar albino rats, weighing 257 to 395 g were used in the present study ( n  = 12). The animals were randomly divided into two equal groups as the sericin and the control group. After intramuscular administration of the anesthetic agent, the rats were intubated and mechanically ventilated. A left thoracotomy was performed and 30 mg sericin powder was instilled into the thoraxes of the sericin group. The remaining rats were allocated to a sham thoracotomy group. The animals were housed in individual cages, fed ad-libitum, and sacrificed 8 days after. After sacrifice, the left hemithoraxes were removed en bloc and underwent histopathologic examination. Results  Masson trichrome staining was applied on the visceral pleura sections of all the animals. Each animal specimen ( n  = 6, 100%) in the control group showed minimal collagen deposition, while only one rat (16.67%) in the sericin group had minimal collagen deposition. However, in the sericin group, five animals (83.33%) showed dense collagen deposition, fibroblastic activity, and fibrosis. According to the test method, independent t -test, developing fibroblastic activity and fibrosis are statistically significant between the two groups ( p  < 0.01). There were no foreign-body reactions and no evidence of biological glue on the specimens in the sericin group. The rats in the sericin group had lower inflammatory reactions compared with those in the control group. Emphysema was observed in two rats (33.33%) in the sericin group and in four rats (66.67%) in the control group. Therefore, sericin was found to be associated with an increase in fibroblastic activity and fibrosis in visceral pleura without exerting any adverse effect on the lung parenchyma. Conclusion  Sericin is a new and researchable protein for chest diseases and thoracic surgery. To develop an effect of dense collagen deposition, fibroblastic activity, and fibrosis in the visceral pleura, without significant adverse effects, is remarkable. Therefore, sericin may be useful as a pleurodesis agent or natural biological glue in the future. Sericin treatment can add value to the disciplines of pulmonology and thoracic surgery.

Objective Diabetic complications and lipid peroxidation are known to have a close association. Lipid peroxidation commonly occurs at sites exposed to ischaemia, but distant organs and tissues also get damaged during ischaemia/reperfusion (I/R). Some of these targets are vital organs, such as the lung, liver, and kidney; the lung is the most frequently affected. The aim of our study was to investigate the effects of dexmedetomidine on I/R damage in lung tissue and on the oxidant/anti-oxidant system in diabetic rats. Material and methods Diabetes was induced with streptozotocin (55 mg/kg) in 18 Wistar Albino rats, which were then randomly divided into three groups (diabetes control (DC), diabetes plus ischaemia-reperfusion (DIR), and diabetes plus dexmedetomidine-ischaemia/reperfusion (DIRD)) after the effects of diabetes were clearly evident. The rats underwent a left thoracotomy and then ischaemia was produced in the myocardium muscle by a left anterior descending artery ligation for 30 min in the DIR and DIRD groups. I/R was performed for 120 min. The DIRD group received a single intraperitoneal dose of dexmedetomidine (100 µg/kg); the DIR group received no dexmedetomidine. Group DC was evaluated as the diabetic control group and also included six rats (C group) in which diabetes was not induced. These mice underwent only left thoracotomy and were closed without undergoing myocardial ischaemia. Histopathological changes, activities of catalase (CAT) and glutathione-S-transferase anti-oxidant enzymes, and malondialdehyde (MDA) levels were evaluated in the lung tissues of all rats. Results Neutrophil infiltration/aggregation was higher in the DIR group than in the C, DC, and DIRD groups (p=0.001, p=0.013, and p=0.042, respectively). The lung injury score was significantly higher in the DIR group than in the C and DC groups (p<0.0001 and p=0.024, respectively). The levels of MDA were significantly higher in the DIR group than in the C and DIRD groups. CAT activity was significantly higher in the DIR group than in the DIRD and C groups. Conclusion Our results confirm that dexmedetomidine has protective effects against the lung damage resulting from I/R in diabetic rats. Future studies conducted to evaluate the effects of the use of dexmedetomidine on damage to various organs following different I/R durations may help understanding possible protective effects of dexmedetomidine and underlying mechanisms in tissue damage related to I/R injury.

Because of the prevalence of methamphetamine abuse worldwide, it is not uncommon for subjects in law enforcement encounters to be methamphetamine-intoxicated. Methamphetamine has been present in arrest-related death cases in which an electronic control device (ECD) was used. The primary purpose of this study was to determine the cardiac effects of an ECD in a methamphetamine intoxication model. Sixteen anesthetized Dorset sheep (26-78 kg) received 0.0 mg/kg (control animals, n = 4), 0.5 mg/kg (n = 4), 1.0 mg/kg (n = 4), or 1.5 mg/kg (n = 4) of methamphetamine hydrochloride as a slow intravenous (IV) bolus during continuous cardiac monitoring. The animals received the following exposures in sequence from a TASER X26 ECD beginning at 30 minutes after the administration of the drug: 1) 5-second continuous exposure, 2) 15-second intermittent exposure, 3) 30-second intermittent exposure, and 4) 40-second intermittent exposure. Darts were inserted at the sternal notch and the cardiac apex, to a depth of 9 mm. Cardiac motion was determined by thoracotomy (smaller animals, < or = 32 kg) or echocardiography (larger animals, > 68 kg). Data were analyzed using descriptive statistics and chi-square tests. Animals given methamphetamine demonstrated signs of methamphetamine toxicity with tachycardia, hypertension, and atrial and ventricular ectopy in the 30-minute period immediately after administration of the drug. Smaller animals (n = 8, < or = 32 kg, mean = 29.4 kg) had supraventricular dysrhythmias immediately after the ECD exposures. Larger animals (n = 8, > 68 kg, mean = 72.4) had only sinus tachycardia after the exposures. One of the smaller animals had frequent episodes of ventricular ectopy after two exposures, including runs of delayed onset, nonsustained six- to eight-beat unifocal and multifocal ventricular tachycardia that spontaneously resolved. This animal had significant ectopy prior to the exposures as well. Thoracotomy performed on three smaller animals demonstrated cardiac capture during ECD exposure consistent with previous animal studies. In the larger animals, none of the methamphetamine-intoxicated animals demonstrated cardiac capture. Two control sheep showed evidence of capture similar to the smaller animals. No ventricular fibrillation occurred after the exposure in any animal. In smaller animals (32 kg or less), ECD exposure exacerbated atrial and ventricular irritability induced by methamphetamine intoxication, but this effect was not seen in larger, adult-sized animals. There were no episodes of ventricular fibrillation after exposure associated with ECD exposure in methamphetamine-intoxicated sheep.

Kinesiology taping (KT) is a rehabilitative technique performed by the cutaneous application of a special elastic tape. We tested the safety and efficacy of KT in reducing postoperative chest pain after lung lobectomy. One-hundred and seventeen consecutive patients, both genders, age 18-85, undergoing lobectomy for lung cancer between January 2013 and July 2015 were initially considered. Lobectomies were performed by the same surgical team, with thoracotomy or video-assisted thoracoscopic surgery (VATS) access. Exclusion criteria (n = 25 patients) were: previous KT exposure, recent trauma, pre-existing chest pain, lack of informed consent, >24-h postoperative intensive care unit treatment. After surgery, the 92 eligible patients were randomized to KT experimental group (n = 46) or placebo control group (n = 46). Standard postoperative analgesia was administered in both groups (paracetamol/non-steroidal anti-inflammatory drugs, epidural analgesia including opioids), with supplemental analgesia boluses at patient request. On postoperative day 1 in addition, in experimental group patients a specialized physiotherapist applied KT, with standardized tape length, tension and shape, over three defined skin areas: at the chest access site pain trigger point; over the ipsilateral deltoid/trapezius; lower anterior chest. In control group, usual dressing tape mimicking KT was applied over the same areas, as placebo. Thoracic pain severity score [visual analogue scale (VAS) ranging 0-10] was self-assessed by all patients on postoperative days 1, 2, 5, 8, 9 and 30. The KT group and the control group had similar demographics, lung cancer clinico-pathological features and thoracotomy/VATS ratio. Postoperatively, the two groups also resulted similar in supplemental analgesia, complication rate, mean duration of chest drainage and length of stay. There were no adverse events with KT application. After tape application, KT patients reported overall less thoracic pain than the control group, the difference being significant on postoperative day 5 [median VAS, 2 (interquartile range, 1-3) vs 3 (2-5), P < 0.01] and day 8 [median VAS, 1 (0-2) vs 2 (1-3), P < 0.05]. Moreover, on postoperative day 30 persistence of chest pain (VAS ≥3) was reported less frequently by the KT group than by the control group (7 vs 24%; P = 0.03). KT after lung lobectomy is a safe and effective auxiliary technique for chest pain control. ISRCTN37253470. © The Author 2016.

2008-08-01

Thoracic surgeons participating in this survey seemed to have clearly indicated their perception of VATS major lung resections, in particular VATS lobectomy. 1. The acronym VATS as a short form of "video-assisted thoracic surgery" was the preferred terminology. 2. According to the respondents, the need or use of rib spreading served as the defining characteristic of "open" thoracic surgery. 3. It was most commonly suggested that VATS lobectomy is performed by means of two or three port incisions with the addition of a minithoracotomy or access incision. 4. Rib spreading (shearing) was not deemed acceptable as part of a strictly defined VATS procedure. 5. Although there was no general consensus, respondents suggested that the preferred approach for visualization in a VATS procedure was only through the video monitor. 6. Although minimally invasive procedures for lung resection are still mainly being used for diagnostic and minor therapeutic purposes, young surgeons seemed to be more likely to recommend VATS lung surgery for major pulmonary resections than their more senior colleagues. 7. The survey confirmed that the use of the standard posterolateral thoracotomy is still widespread. Almost 40% of the surgeons claimed to use the standard posterolateral thoracotomy for more than 50% of their cases and less than 30% use it for less than 5% of cases. 8. The major reasons to perform VATS lobectomy were perceived to be reduced pain and decreased hospitalization. 9. Approximately 60% of the surgeons claimed to perform VATS lobectomy in less than 5% of their lobectomy cases. Younger consultants reported using VATS lobectomy in up to 50% of their lobectomy cases. There was the suggestion that lack of resources could justify the minor impact of VATS lobectomy in the thoracic surgical practice in middle- to low-income countries. 10. The currently available scientific evidence on safety and effectiveness, and technologic advancements were emphasized as the two factors having a major impact on the development of minimally invasive thoracic surgical practice. 11. Any lack of popularity of VATS lobectomy was presumed to be caused by several equally important factors. Resistance to change by more senior surgeons ranked highly among younger surgeons, however, as an explanation for the slow adoption of this technique. Senior surgeons. however, seemed to focus their attention on the steep learning curve of VATS lobectomy. In addition, surgeons from middle- to low-income countries recognized certain financial and logistic difficulties as major determinants of the lack of popularity of VATS lobectomy. 12. Most surgeons thought that robotic thoracic surgery represented an evolution of VATS. Nevertheless, almost 30% did not think current robotic methods meet the criteria for minimally invasive surgery. More than 90% of the participants stated that they did not perform robotic thoracic surgery. This was reportedly because of costs. but also because of the fact that robotic approaches have not yet demonstrated a distinct advantage over nonrobotic VATS procedures. 13. It was suggested that in every unit or department there should be at least one surgeon with a specific interest and capability in VATS lobectomy. The younger surgeons. however, seemed to envisage more widespread competency being optimal. 14. Most suggested that training in VATS lobectomy be done in a stepwise fashion starting from the classical open technique. Older surgeons wanted to see this as an extracurricular activity following completion of the current training curriculum rather than included in the traditional training program. In the opinion of the thoracic surgeons taking part in this survey, pulmonary resections not performed according to these standards could not be called VATS procedures but should be included within the MITS category at large, along with other diagnostic and therapeutic interventions. In addition, the survey confirmed that the time-honored muscle-dividing thoracotomy is still widely used. The opportunity for a progressive move toward the routine use of less invasive approaches for major pulmonary resections, however, is already well within sight. Given the results of the ESTS survey supporting a stepwise teaching process leading to VATS lobectomy, hybrid and minimally invasive open lung resections (discussed elsewhere in this issue) collectively defined as MITS may serve as starting point in this process to expand the appropriate use of VATS lobectomy in the modern thoracic surgical practice.

We previously reported that cancer cells may be detected through pleural lavage cytology (PLC). In this study, we sought to re-examine the prognostic significance of the PLC status based on an extended dataset with an additional follow-up period. Pleural lavage following thoracotomy was cytologically examined in 1,317 consecutive patients who were diagnosed with NSCLC between 1987 and 2004 at the Thoracic Surgery Units of Kobe University Graduate School of Medicine and Hyogo Cancer Center. Among the investigated patients, 46 exhibited positive cytological findings. The prognosis of these patients was significantly worse compared to that of patients without positive PLC. Of the 844 pathological stage I patients, 18 had a positive PLC status and their prognosis was significantly worse compared to that of patients with stage I disease without positive PLC. In conclusion, positive PLC findings were associated with a poor prognosis and this finding was significant for patients with stage I disease. These results suggest the need for PLC status evaluation during staging and treatment planning in patients with NSCLC.

Intraoperative pneumothorax is a rare complication with a high risk of cardiorespiratory arrest by gas tamponade especially on a single lung. We report the case of a female patient aged 53 years who benefited from a left pneumonectomy on pulmonary tuberculosis sequelae. The patient presented early postoperative anemia with a left hemothorax requiring an emergency thoracotomy. In perioperative, the patient had a gas tamponade following a pneumothorax of the remaining lung, and the fate has been avoided by an exsufflation. Intraoperative pneumothorax can occur due to lesions of the tracheobronchial airway, of the brachial plexus, the placement of a central venous catheter or barotrauma. The diagnosis of pneumothorax during unipulmonary ventilation is posed by the sudden onset of hypoxia associated with increased airway pressures and hypercapnia. The immediate life-saving procedure involves fine needle exsufflation before the placement of a chest tube. Prevention involves reducing the risk of barotrauma by infusing patients with low flow volumes and the proper use of positive airway pressure, knowing that despite protective ventilation, barotraumas risk still exists.

Plication of a nonfunctional hemidiaphragm usually restores altered ventilatory mechanics. This study compared two techniques in performing diaphragmatic plication: video-assisted thoracoscopy (group A) and thoracotomy (group B). Twenty dogs with induced paralysis of the right hemidiaphragm were randomly assigned to one of the two groups. Evaluations were performed before and after plication of the respiratory frequency (f) and lung area (LA) of the affected side. Operative time, time to resumption of walking, ingestion of fluids and solid food, pain intensity, and postoperative complications were measured. Group A had less pain after the surgery (P < 0.0001), earlier fluid ingestion (P < 0.05), and earlier resumption of walking (P < 0.019). Four weeks after the procedure, LA was similar in both groups, while a significant decrease in f was recorded in group A (P < 0.02). The remaining evaluated variables showed no differences. Both approaches were effective. Pain recorded in the postoperative period was less and recovery was faster in group A. Complications and surgical times were similar. The video-assisted thoracoscopy is a safe and efficient option for performing diaphragmatic plication in dogs.

2010-01-01

The Paracor HeartNet, a ventricular constraint device for the treatment of heart failure (HF), is implanted through a left lateral thoracotomy. It envelopes the heart like a mesh "bag." This method of application raises the question of whether adhesions with the pericardium allow the safe implantation of a left ventricular assist device (LVAD) if HF worsens. A male patient who had undergone implantation of the Paracor HeartNet 42 months earlier presented with advanced HF for cardiac transplantation. The patient's condition deteriorated, and because no suitable organ for transplantation was available, implantation of an LVAD became necessary. Surgery was performed via a median sternotomy without complications. No severe adhesions were found. This is the first report on "how to do" LVAD implantation after Paracor HeartNet implantation with images and information about cutting the constraint. Because the Paracor HeartNet is "wrapped" around the heart, concerns persist that severe adhesions with the pericardium might occur. In this case, LVAD implantation after therapy with the Paracor HeartNet was without complications, and the expected massive adhesions were absent.

Thoracic trauma is a challenging situation with potential severe chest wall and intrathoracic organ injuries. We present a case of emergent surgery in a 23-year-old man with hemorrhagic shock due to massive lung and chest wall injury after thoracic trauma in a water slide. We performed a SI-VATS approach in order to define intrathoracic and chest wall injuries, and once checked the extension of the chest wall injury, we added a middle size thoracotomy just over the affected area in order to stabilize rib fractures with Judet plates, that had caused massive laceration in left lower lobe (LLL) and injured the pericardium causing myocardical tear. After checking bronchial and vascular viability of LLL we suggested a lung parenchyma preserving technique with PTFE protected pulmonary primary suture in order to avoid a lobectomy. Chest tubes were removed on 3 rd postoperative day and patient was discharged on 14 th postoperative day. He has already recovered his normal activity 6 months after surgery.

A fistula formation between the esophagus and an aberrant right subclavian artery is a rare but fatal complication that has been mostly described in the setting of prolonged nasogastric intubation and foreign body erosion. We report a case of a young morbidly obese patient who underwent sleeve gastrectomy that was complicated by a postoperative leak at the level of the gastroesophageal junction. A covered esophageal stent was placed endoscopically to treat the leak. The patient developed massive upper gastrointestinal bleeding secondary to the erosion of the stent into an aberrant retroesophageal right subclavian artery twelve days after stent placement. She was ultimately treated by endovascular stenting of the aberrant right subclavian artery followed by thoracotomy and esophageal repair over a T-tube. This case report highlights the multidisciplinary approach needed to diagnose and manage such a devastating complication. It also emphasizes the need for imaging studies prior to stent deployment to delineate the vascular anatomy and rule out the possibility of such an anomaly in view of the growing popularity of esophageal stents, especially in the setting of a leak.

Patients referred for aortic valve replacement are often elderly and may have increased surgical risk associated with ascending aortic calcification, left ventricular dysfunction, presence of coronary artery disease, previous surgery, and/or presence of several co-morbidities. Some of these patients may not be considered candidates for conventional surgery because of their high risk profile. While transcatheter aortic valve replacement constitutes a widely accepted alternative, some patients may not be eligible for this modality due to anatomic factors. Apico-Aortic Conduit (AAC) insertion (aortic valve bypass surgery) constitutes a possible option in those patients. Apico-Aortic Conduit is not a new technique, as it has been used for decades in both pediatric and adult populations. However, there is a resurging interest in this technique due to the expanding scope of elderly patients being considered for the treatment of aortic stenosis. Herein, we describe our surgical technique and provide a systematic review of recent publications on AAC insertion, reporting that there is continued use and several modifications of this technique, such as performing it through a small thoracotomy without the use of the cardiopulmonary bypass.

Peripheral pulmonary nodules are preferably removed by minimally invasive techniques, such as video-assisted thoracoscopic (VATS) surgery. These nodules should be marked preoperatively for better intraoperative detection and removal. Twenty-two cases with a single pulmonary nodule requiring surgical removal for histologic examination were included in a prospective study. Guided by computed tomography, nodules were marked preoperatively using a laser marker system and fixed with a spiral wire. The marked nodules were removed by VATS surgery immediately after the marking. The marking wire was placed in all 22 patients without any complications. The marked nodule was completely removed by VATS surgery in 19 patients. Conversion to thoracotomy was necessary in 3 patients, twice because of thoracoscopy-related problems and once because of a marking failure. The average times for the marking procedure and operation were 24 minutes and 32 minutes, respectively. This new method of computed tomography-guided nodule marking with a spiral wire and subsequent VATS surgery is very efficient in terms of localization and stable fixation of subpleural pulmonary nodules.

Robotic-Assisted Thoracic Surgery for Early-Stage Lung Cancer: A Review.

PubMed

Brooks, Paula

2015-07-01

This review evaluates the benefits and disadvantages associated with the use of robotic-assisted technology in performing lobectomies in patients with early-stage lung cancer. The author conducted a literature search of Ovid®, MEDLINE®, PubMed®, and CINAHL® for articles published from 2005 to 2013. Search criteria included key terms such as robot, robotic, robotic-assisted lobectomy, and lung cancer. Of 922 articles, the author included a total of 12 research-based published studies in the analysis and incorporated the findings into an evidence table. Results showed that robotic-assisted lobectomies are feasible safe procedures for patients with stage 1A or 1B lung cancer; however, there is a steep learning curve and long-term randomized studies evaluating robotic-assisted lobectomy and conventional posterolateral thoracotomy or video-assisted thoracic lobectomy are needed. For patient safety, perioperative nurses should be aware of the length of time and experience required to perform these procedures, the costs, techniques, benefits, and disadvantages.

To evaluate intraventricular systolic dyssynchrony in rats with post-infarction heart failure by quantitative tissue velocity imaging combining synchronous electrocardiograph. A total of 60 male SD rats were randomly assigned to 3 groups: a 4 week post-operative group and an 8 week post-operation group (each n=25, with anterior descending branch of the left coronary artery ligated), and a sham operation group (n=10, with thoracotomy and open pericardium, but no ligation of the artery). The time to peak systolic velocity of regional myocardial in the rats was measured and the index of the left intraventricular dyssynchrony was calculated. All indexes of the heart function became lower as the heart failure worsened except the left ventricle index in the post-operative groups. All indexes of the dyssynchrony got longer in the post-operative groups (P<0.05), while the changes in the sham operation group were not significantly different (P>0.05). Quantitative tissue velocity imaging combining synchronous electrocardiograph can analyse the intraventricular systolic dyssynchrony accurately.

Multiple organ metastases from colorectal carcinoma may be considered incurable, but long survival after both liver and lung resection for metastases has been reported. A retrospective analysis of 48 patients who underwent lung resection for metastatic colorectal cancer between 1992 and 1999 was undertaken. Twenty-seven patients had lung metastasis alone, 15 had previous partial hepatectomy, and six had previous resection of local or lymph node recurrence. The relationship of clinical variables to survival was assessed. Survival was calculated from the time of first pulmonary resection. Five-year survival rates after resection of lung metastasis were 73 per cent in patients without preceding recurrence, 50 per cent following previous partial hepatectomy and zero after resection of previous local recurrence. Independent prognostic variables that significantly affected survival after thoracotomy were primary tumour histology and type of preceding recurrence. There was no significant difference in survival after lung resection between patients who had sequential liver and lung resection versus those who had lung resection alone. Sequential lung resection after partial hepatectomy for metastatic colorectal cancer may lead to long-term survival.

This retrospective analysis reviews the clinical experience of a major urban referral hospital with diffuse malignant pleural mesothelioma during the 14-year period from 1973 through 1986. Seventy-five cases of definite or equivocal mesothelioma were identified. There were four cases of primary malignant peritoneal mesothelioma, seven cases of benign fibrous mesothelioma, and 64 cases of diffuse malignant pleural mesothelioma. In 43 cases (67%) of diffuse malignant pleural mesothelioma, there was historic evidence of asbestos exposure. In 21 cases (33%), there was no known history of asbestos exposure. An increase in annual incidence of diffuse malignant pleural mesothelioma was observed over themore » study period, from three cases in 1973 to ten cases in 1986. Despite greater awareness of this disease, the diagnosis remains a difficult one to establish given the nonspecific symptoms, signs and radiographic appearance, variable histologic appearance, and poor diagnostic sensitivity and specificity of thoracentesis and closed pleural biopsy. Thoracotomy, thoracoscopy, and CT-guided needle biopsies gave higher yields and are the diagnostic measures of choice when diffuse malignant pleural mesothelioma is suspected.« less

Group A beta-haemolytic streptococcal acute chest event in a child with sickle cell anaemia.

PubMed

Suara, R O

2001-06-01

Acute chest syndrome is a major cause of death and hospitalisation in children with sickle cell anaemia. It is often initiated by an infection, particularly pneumonia. Microbial agents previously not associated with acute chest syndrome are becoming increasingly important. Group A beta-haemolytic Streptococcus (GABHS) is thought to be an uncommon cause of pneumonia in children with sickle cell anaemia. We report a 15-year-old African-American girl who presented with an acute chest event characterised by fever, cough, chest pain, shortness of breath, right upper abdominal quadrant pain, jaundice and otitis media. Chest radiograph showed multi-lobar pneumonia with left pleural effusion. Group A beta-haemolytic Streptococcus was isolated from culture of pleural and middle ear fluids. She responded to therapy that included antibiotics, exchange blood transfusion, oxygen, thoracotomy chest tube drainage and decortication. In a child with sickle cell anaemia presenting with fever and an acute chest event, pneumonia should be considered and GABHS recognised as a possible aetiological agent. In addition, a chest X-ray should be obtained and antibiotics against agents causing community-acquired pneumonia instituted.

One-hundred-sixty-nine lung cancers have occurred to date among 10,040 cigarette smoking men who participated in the New York Lung Cancer Detection Program. Almost 40% of the cases, 65, were still Stage I when their disease was diagnosed; 62 had thoracotomy and resection, and in 57, mediastinal node dissection confirmed that the mediastinum was free of metastases ("true pathologic" Stage I). Fifty-four of the 62 (87%) are still alive at this time, while only 15 of 104 (14%) of those with Stage II and III lung cancers are alive. Only two patients of the 62 in Stage I who were treated by resection died of lung cancer, both with T2 tumors. Two others are alive with metastases, one died postoperatively, and five died of other causes without evidence of lung cancer. The estimated probability of survival for true Stage I lung cancer is over 90% at five years, and close to 40% of all lung cancers can be detected in this favorable stage by present radiologic and cytologic screening techniques.

Applications of laser in ischemic heart disease in China

NASA Astrophysics Data System (ADS)

Chen, Mingzhe; Zhang, Yongzhen

1999-09-01

Current data demonstrate that laser coronary angioplasty is most useful in complex lesions not well suited for percutaneous transluminal coronary angioplasty (PTCA). It is not `stand-alone' procedure, and should be considered an adjunct to PTCA or stenting. To date, there are not data supporting reduction of restenosis. Direct myocardial revascularization (DMR), either transmyocardial revascularization (TMR) or percutaneous (catheter-based) myocardial revascularization (PMR), uses laser to create channels between ischemic myocardium and left ventricular cavity. Candidates include patients with chronic, severe, refractory angina and those unable to undergo angioplasty or bypass surgery because conduits or acceptable target vessels are lacking. Although the mechanisms of action of DMR have not yet been clearly elucidated, but several theories have been proposed, including channel patency, angiogenesis, and denervation. TMR, typically requiring open thoracotomy, is effective for improving myocardial perfusion and reducing angina. Pilot studies demonstrate that clinical application of PMR is feasible and safe and effective for decreasing angina. Late sequelae also remain to be determined. An ongoing randomized clinical trial is comparing PMR with conventional medical therapy in patients with severe, refractory angina and disease unamenable to angioplasty or bypass surgery.

A 22-year-old soldier was shot in the left chest by a bullet from close range. He was found to have a left haemothorax and remained shocked despite aggressive resuscitation. Due to difficult terrain and night time movement restrictions, there were limitations to the transfer of patient. So he was attended at a peripheral hospital. At emergency thoracotomy, three segmental arteries to left upper lobe were ligated and haemostasis was secured. The level of transection of left lower lobe bronchus was identified to be below the origin of the apical segmental bronchus. The lower lobe bronchus was successfully re-attached and followed up with a daily bronchoscopic clearance of distal airway. The patient made a full recovery. Anastomosis of left lower lobe bronchus after traumatic transection is a viable option for preserving an amputated lobe, in trauma settings, provided haemostatic control has been adequately achieved.

Laparoscopic transhiatal esophagectomy, indicated for benign and malignant esophageal diseases, is a complex operation, often associated with a high rate of morbidity and mortality. During the past decade this technique has became well accepted among specialized surgeons for the treatment of esophageal cancer, avoiding thoracotomy and reducing open access complications. The aim of the present study was to retrospectively analyze patients with esophageal cancer who underwent laparoscopic transhiatal esophagectomy. From November 1993 to August 2006, 78 patients underwent laparoscopic transhiatal esophagectomy. There were 68 cases of esophageal cancer (57 males and 21 females, age range = 28-73 years) with a predominant rate of squamous cell carcinoma (60.2%). The conversion rate was 6.4%. The mean operative time was 153 min with a 12.8% rate of cervical leak and a postoperative (30-day) mortality rate of 5.1%. The four-year survival rate was 19% as determined within a subgroup of 21 patients whose followup during the period was possible. Laparoscopic transhiatal esophagectomy is a safe alternative for experienced professionals. This access can improve mortality, hospital stay, and other outcomes when compared with open methods.

Early pain and persistent parietal disorders remains a major unresolved problem in thoracic surgery. Thoracotomy and the use of multiple ports in most Video Assisted Thoracic Surgery (VATS) procedures are the major cause of this persistent pain. For the last decade, a few publications describing the use of either single incision VATS and cervical thoracic approaches have been reported without significant results in comparison with current used techniques. Intercostals compression during surgery and early after by intercostals chest tube placement, are probably the major cause of postoperative pain. Flexible endoscope is currently used in several surgeries and will take more and more importance in our daily use in thoracic surgery. Instrument flexibility allows its use through minimally invasive approaches and offers a very interesting intra-thoracic navigation. We describe here the first use in France of a flexible endoscope in thoracic surgery through a single cervical incision to perform simultaneous exploration and biopsies of the mediastinum and right pleura using the original approach of Cervical Incision Thoracic Endoscopic Surgery (CITES).

2014-11-01

Reduction in working hours, streamlined training schemes and increasing use of endovascular techniques has meant a reduction in operative experience for newer vascular surgical trainees, especially those exposures which are not routinely performed such as thoracoabdominal, thoracotomy and retroperitoneal aortic, for example. This paper describes an Advanced Anatomy of Exposure course which was designed and convened at the Clinical Training & Evaluation Centre in Western Australia and uses fresh frozen cadavers. Feedback was obtained from the participants who attended over three courses by questionnaire. Feedback was strongly positive for the course meeting both its learning outcomes and personal learning objectives, and in addition, making a significant contribution to specialty skills. Most participants thought the fresh frozen cadaveric model significantly improved the learning objectives for training. The fresh frozen cadaver is an excellent teaching model highly representative of the living open surgical scenario where advanced trainees and newly qualified consultants can improve their operative confidence and consequently patient safety in vascular surgery. An efficient fresh frozen cadaver teaching programme can benefit many health professionals simultaneously maximizing the use of donated human tissue. © 2013 Royal Australasian College of Surgeons.

Robotic-Assisted Videothoracoscopic Surgery of the Lung.

2015-07-01

Despite initial concerns about the general safety of videothoracoscopic surgery, minimally invasive videothoracoscopic surgical procedures have advantages over traditional open thoracic surgery via thoracotomy. Robotic-assisted minimally invasive surgery has expanded to almost every surgical specialty, including thoracic surgery. Adding a robotic-assisted surgical system to a videothoracoscopic surgical procedure corrects several shortcomings of videothoracoscopic surgical cameras and instruments. We performed a literature search on robotic-assisted pulmonary resections and compared the published robotic series data with our experience at the H. Lee Moffitt Cancer Center & Research Institute. All perioperative outcomes, such as intraoperative data, postoperative complications, chest tube duration, hospital length of stay (LOS), and in-hospital mortality rates were noted. Our literature search found 23 series from multiple surgical centers. We divided the literature into 2 groups based on the year published (2005-2010 and 2011-2014). Operative times from earlier studies ranged from 150 to 240 minutes compared with 90 to 242 minutes for later studies. Conversion rates (to open lung resection) from the earlier studies ranged from 0% to 19% compared with 0% to 11% in the later studies. Mortality rates for the earlier studies ranged from 0% to 5% compared with 0% to 2% for the later studies. Since 2010, our group has performed more than 600 robotic-assisted thoracic surgical procedures, including more than 200 robotic-assisted pulmonary lobectomies, which we also divided into 2 groups. Our median skin-to-skin operative time improved from 179 minutes for our early group (n = 104) to 172 minutes for our later group (n = 104). The overall conversion rate was 9.6% and the emergent conversion rate (for bleeding) was 5% for our robotic-assisted lobectomies. The most common postoperative complications in our cohort were prolonged air leak (> 7 days; 16.8%) and atrial fibrillation (12%). Hospital LOS for the early series ranged from 3 to 11 days compared with 2 to 6 days for the later series. Median hospital LOS decreased from 6 to 4 days. Our mortality rate was 1.4%; 3 in-hospital deaths occurred in the early 40 cases. Mediastinal lymph node (LN) dissection and detection of occult mediastinal LN metastases were improved during robotic-assisted lobectomy for non-small-cell lung cancer, as demonstrated by an overall 30% upstaging rate, including a 19% nodal upstaging rate, in our cohort. Robotic-assisted videothoracoscopic pulmonary lobectomy appears to be as safe as conventional videothoracoscopic surgical lobectomy, which has decreased perioperative complications and a shorter hospital LOS than open lobectomy. Both mediastinal LN dissection and the early detection of occult mediastinal LN metastatic disease were improved by robotic-assisted videothoracoscopic surgical compared with conventional videothoracoscopic surgical or open thoracotomy.

We performed this observational prospective study to evaluate the results of the application of a diagnostic and therapeutic algorithm for complicated parapneumonic pleural effusion (CPPE) and pleural parapneumonic empyema (PPE). From 2001 to 2007, 210 patients with CPPE and PPE were confirmed through thoracocentesis and treated with pleural drainage tubes (PD), fibrinolytic treatment or surgical intervention (videothoracoscopy and posterolateral thoracotomy). Patients were divided into 3 groups: I (PD); II (PD and fibrinolytic treatment); IIIa (surgery after PD and fibrinolysis), and IIIb (direct surgery). The statistical study was done by variance analysis (ANOVA), χ2 and Fisher exact test. The presence of alcohol or drug consumption, smoking and chronic obstructive pulmonary disease (COPD) were strongly associated with a great necessity for surgical treatment. The IIIa group was associated with increased drainage time, length of stay and complications. No mortality was observed. The selective use of PD and intrapleural fibrinolysis makes surgery unnecessary in more than 75% of cases. The selective use of PD and fibrinolysis avoids surgery in more than 75% of cases. However, patients who require surgery have more complications, longer hospital stay, and more days on PD and they are more likely to require admittance to the Intensive Care Unit.

Lung Middle Lobe Laceration Needing Lobectomy as Complication of Nuss Bar Removal.

2018-01-01

Minimally invasive procedure for the treatment of pectus excavatum as described by Nuss has been used from 1987. The bar initially introduced blindly is now introduced under thoracoscopic control to increase safety of the procedure. It is usually removed two to three years after its insertion in a one-day procedure. Complications of the bar removal are rare but potentially serious. We report the case of a serious complication which occurred immediately after the Nuss bar removal. A 15-year-old boy underwent a Nuss procedure for a severe pectus excavatum without relevant complication. The bar has been removed two years after its insertion in a minimally invasive procedure. Unfortunately, he developed in the immediate postoperative period a hemopneumothorax due to a right middle lobe laceration which required a middle lobectomy by thoracotomy for hemostasis. Lesions of intrathoracic organs are a rare but potentially serious complication of the removal of the Nuss bar. We now propose to perform this procedure under thoracoscopic control to avoid it. In our experience, adhesions between the bar and the pleura are always present, and those with potential risk for bleeding or inducing intrathoracic organ lesions are suppressed prior to the bar removal.

Patients with congestive heart failure who are supported with a left ventricular assist device (LVAD) may experience right ventricular dysfunction or failure that requires support with a right ventricular assist device (RVAD). To determine the feasibility of using a clinically available axial flow ventricular assist device as an RVAD, we implanted Jarvik 2000 pumps in the left ventricle and right atrium of two Corriente crossbred calves (approximately 100 kg each) by way of a left thoracotomy and then analyzed the hemodynamic effects in the mechanically fibrillated heart at various LVAD and RVAD speeds. Right atrial implantation of the device required no modification of either the device or the surgical technique used for left ventricular implantation. Satisfactory biventricular support was achieved during fibrillation as evidenced by an increase in mean aortic pressure from 34 mm Hg with the pumps off to 78 mm Hg with the pumps generating a flow rate of 4.8 L/min. These results indicate that the Jarvik 2000 pump, which can provide chronic circulatory support and can be powered by external batteries, is a feasible option for right ventricular support after LVAD implantation and is capable of completely supporting the circulation in patients with global heart failure.

Real-time 3D transesophageal echocardiography-guided closure of a complicated patent ductus arteriosus in a dog.

2017-06-01

Advanced imaging modalities are becoming more widely available in veterinary cardiology, including the use of transesophageal echocardiography (TEE) during occlusion of patent ductus arteriosus (PDA) in dogs. The dog in this report had a complex history of attempted ligation and a large PDA that initially precluded device placement thereby limiting the options for PDA closure. Following a second thoracotomy and partial ligation, the morphology of the PDA was altered and device occlusion was an option. Angiographic assessment of the PDA was limited by the presence of hemoclips, and the direction of ductal flow related to the change in anatomy following ligature placement. Intra-operative TEE, in particular real-time three-dimensional imaging, was pivotal for assessing the PDA morphology, monitoring during the procedure, selecting the device size, and confirming device placement. The TEE images increased operator confidence that the size and location of the device were appropriate before release despite the unusual position. This report highlights the benefit of intra-operative TEE, in particular real-time three-dimensional imaging, for successful PDA occlusion in a complicated case. Copyright © 2017 Elsevier B.V.

To report the surgical treatment of a pulmonary emphysematous cyst concurrent with primary pulmonary bronchoalveolar papillary carcinoma in a dog. Clinical case report. 12-year-old 6.4 kg spayed female Shih Tzu dog. The dog presented for surgical treatment of pulmonary emphysema. Radiography revealed that more than half of the left caudal lung lobe was enlarged and hyperlucent and computed tomography (CT) confirmed the presence of an emphysematous space. Thoracoscopic lung lobectomy was attempted but was converted to an intercostal thoracotomy due to poor visualization and pleural adhesions. A left caudal total lung lobectomy was performed using a self-cutting endoscopic stapler. The dog recovered uneventfully and a postoperative histopathologic diagnosis of pulmonary cystic bronchoalveolar papillary carcinoma was made. Re-evaluation using a CT scan with contrast study on postoperative days 27 and 177 revealed no evidence of residual, metastatic, or recurrent lesions. The dog has been doing well since surgery during the 11 month follow-up period. This case report suggests a potential relationship between pulmonary emphysematous diseases and primary lung tumors in dogs. © 2016 The American College of Veterinary Surgeons.

Survival after heart and coronary-artery penetration by an air-rifle projectile.

Gunshot injuries of the heart are extremely rare thoracic traumas in Europe during peacetime. Concomitant lesions of the coronary arteries occur in less than 5%. This case reports on a 26-year-old man who was shot with an air rifle at short range. On admission the patient showed signs of pericardial tamponade. Emergency thoracotomy was performed and a frontal cardiac lesion was found in the distal third of the anterior descending branch of the left coronary artery. The bullet crossed the cavum of the left ventricle and remained in the posterior wall in the subepicardial layer adjacent to the posterior descending coronary branch. Under the conditions of extracorporeal circulation we removed the bullet, repaired both ventricle walls using patches in sandwich technique, and bypassed the coronary lesion by single aortocoronary venous graft. No signs of myocardial infarction could be detected by ECG. The follow-up after 3 years shows no cardiac problems and normal stress tolerance. This case report proves that even air rifle shots, which in general are considered to be harmless, may result in life-threatening injuries. For the severity of the injury are decisive the kinetic energy at the muzzle as well as configuration and type of the bullet.

Ventricular, but not atrial, M2-muscarinic receptors increase in the canine pacing-overdrive model of heart failure.

To investigate the effects of heart failure induced by chronic rapid ventricular pacing (six weeks) on canine atrial and ventricular muscarinic receptors. Dogs (n = 4) were fitted with a bipolar pacing electrode connected to a Medtronic pacemaker set at 240 stimuli/min. Pacing was maintained for six weeks. Tissue samples obtained from the left atrium and ventral wall of the left ventricle were frozen at -70 degrees C. Control tissue was obtained from normal dogs (n = 6) following anesthesia and thoracotomy. M2-muscarinic receptors were characterized and quantified in tissue micropunches using the hydrophilic ligand [3H] N-methyl-scopolamine (NMS). Cardiac tissue bound [3H] NMS with the specificity of an M2 subtype. Tachycardia-induced heart failure did not affect atrial muscarinic receptors but signify left ventricular myocytes (control 160.0 +/- 10.0 fmol/mg protein versus heart failure 245.0 +/- 25.0 fmol/mg protein; P < 0.01). Canine ventricular muscarinic receptors display a specificity for the M2 subtype. In contrast to previous work, tachycardia-induced heart failure was accompanied by an increase (+ 53%) in ventricular, but not atrial, M2 receptors compared with normal dogs.

The Mitra-Spacer (Cardiosolutions, Bridgewater, MA, USA) is designed to treat mitral regurgitation by introducing a dynamic spacer that constantly adapts to the changing haemodynamic conditions during the cardiac cycle. We aimed to evaluate the performance and safety of this device in the chronic ovine model. Eight sheep were enrolled in this study. Through a left thoracotomy, the Mitra-Spacer was inserted via the transapical approach and advanced into the left atrium (LA) under imaging guidance. Device performance and safety were evaluated up to 90 days using fluoroscopy, echocardiography and histopathology. The volume within the balloon spacer shifted during the cardiac cycle in all cases. Seven animals survived up to 90 days for terminal imaging and tissue harvest. Echocardiography showed no change in left ventricle (LV) ejection fraction from baseline to 90 days. There were no observations of changes in LV diastolic function, pulmonary vein inflow, or tricuspid valve function. Histological analysis demonstrated no significant injury to the mitral apparatus. In the healthy ovine model, Mitra-Spacer implantation was feasible and safe. At 90 days, no evidence of structural damage to the mitral apparatus or deterioration of cardiac performance was demonstrated.

This retrospective study was carried out to evaluate the indications for and outcomes of the hemiclamshell (HCS) approach (longitudinal partial sternotomy with antero-lateral thoracotomy) in patients undergoing mass resection in thoracic surgery. All patients (50) who underwent a HCS procedure in our department, between July 1996 and July 2005, were studied retrospectively, analyzing the indications, morbidity and outcome (pain, neurological or shoulder defects, mortality) at one month and one year. The main indications were apical tumours (38%), tumours of the cervicothoracic junction (46%) and chest wall (10%), and 'bulky' tumours (6%). One-month mortality was 6%. Two patients suffered from a chylothorax and one from phrenic paralysis. The postoperative analgesic requirements were similar to those after other thoracic surgery approaches. Twelve percent of patients suffered pain at one month and 6% at one year. Shoulder dysfunction was observed in 10% of patients at one month and 6% at one year. In conclusion, the HCS surgical approach was associated with an uncomplicated postoperative course. This anterior approach is suitable for apical tumours, tumours of the cervicothoracic junction and 'bulky' lung tumours, providing good access for control of the large vessels and radical mediastinal clearance.

Cystic echinococcosis: late rupture and complication of a stable pulmonary cyst.

2011-01-01

Cystic echinococcosis is observed worldwide. Traditional management includes an invasive surgical approach with adjunctive chemotherapy. It has been suggested that observation alone may be appropriate in asymptomatic individuals with stable cysts. A case involving a 38-year-old Peruvian man with an asymptomatic bronchogenic cyst (suspected to be due to echinococcus, but never definitely diagnosed) is presented. The cyst was first noted in 1998, and was followed for 10 years during which time he remained asymptomatic with minimal radiographic change. One year later, in 2009, he presented with acute rupture of the cyst causing empyema. The patient required thoracotomy, decortication and resection of the ruptured cyst. Final pathology showed Echinococcus organisms. The patient responded well to treatment with albendazole and praziquantel, and became completely asymptomatic within six months. The present case demonstrates that echinococcal cysts may be at risk of spontaneous rupture, even after many years of clinical stability, thus supporting the case for resection of asymptomatic cysts suspected of being echinococcal at the time of diagnosis. In addition, the case illustrates that medical therapy with albendazole and praziquantel, in conjunction with surgical drainage, can be successful in the treatment of echinococcal empyema.

We aimed to evaluate the effectiveness of intervention by a perioperative multidisciplinary support team for radical esophagectomy for esophageal cancer. We retrospectively reviewed 85 consecutive patients with esophageal cancer who underwent radical esophagectomy via right thoracotomy or thoracoscopic surgery with gastric tube reconstruction. Twenty-one patients were enrolled in the non-intervention group (group N) from May 2011 to September 2012, 31 patients in the perioperative rehabilitation group (group R) from October 2012 to April 2014, and 33 patients in the multidisciplinary support team group (group S) from May 2014 to September 2015. Morbidity rates were 38, 45.2, and 42.4% for groups N, R, and S, respectively. Although there were no significant differences in the incidence of pneumonia among the groups, the durations of fever and C-reactive protein positivity were shorter in group S. Moreover, postoperative oral intake commenced earlier [5.9 (5-8) days] and postoperative hospital stay was shorter [19.6 (13-29) days] for group S. The intervention by a perioperative multidisciplinary support team for radical esophagectomy was effective in preventing the progression and prolongation of pneumonia as well as earlier ambulation, oral feeding, and shortening of postoperative hospitalization.

Myocardial infarction is the most common cause of congestive heart failure. The objective of this work is to evaluate, in experimental animals, morphological and histological effects of the implantation of autologous platelet-rich plasma in infarcted heart sheep. Twenty-four ewes were used, they were surgically infarcted through left thoracotomy and two coronary arteries were ligated (first and second diagonal). After coronary artery ligation three sheep died of ventricular fibrillation. Three weeks after coronary ligation, sheep were reoperated through median sternotomy. Normal saline solution was injected in the infarcted zone in 6 of them (control group) whereas platelet gel was injected in 15 of them. All sheep were euthanized at 9 weeks of evolution of the second surgery. Noteworthy is the formation of new vessels in hematoxylin-eosin-stained sections and factor viii in plasma rich in growth-factors (PRGF)-treated hearts. Injection of platelet growth factors, PRGF, in previously infarcted sheep hearts promotes mitogenesis and angiogenesis. The use of autologous PRGF is simple and safe, causing no toxicity or immune-inflammatory reactions. Copyright © 2012 Instituto Nacional de Cardiología Ignacio Chávez.

Minimally invasive myotomy for the treatment of esophageal achalasia: evolution of the surgical procedure and the therapeutic algorithm.

PubMed

Bresadola, Vittorio; Feo, Carlo V

2012-04-01

Achalasia is a rare disease of the esophagus, characterized by the absence of peristalsis in the esophageal body and incomplete relaxation of the lower esophageal sphincter, which may be hypertensive. The cause of this disease is unknown; therefore, the aim of the therapy is to improve esophageal emptying by eliminating the outflow resistance caused by the lower esophageal sphincter. This goal can be accomplished either by pneumatic dilatation or surgical myotomy, which are the only long-term effective therapies for achalasia. Historically, pneumatic dilatation was preferred over surgical myotomy because of the morbidity associated with a thoracotomy or a laparotomy. However, with the development of minimally invasive techniques, the surgical approach has gained widespread acceptance among patients and gastroenterologists and, consequently, the role of surgery has changed. The aim of this study was to review the changes occurred in the surgical treatment of achalasia over the last 2 decades; specifically, the development of minimally invasive techniques with the evolution from a thoracoscopic approach without an antireflux procedure to a laparoscopic myotomy with a partial fundoplication, the changes in the length of the myotomy, and the modification of the therapeutic algorithm.

Purpose: solitary fibrous tumors (SFT) represent a heterogeneous group of primary pleural neoplasms with a low incidence rate and of which the biological origin, which consists of mesenchymal cells, is uncertain. Methods: The authors present herewith a retrospective analysis of 22 patients with SFTs who were diagnosed and surgically treated between the years 2000–2015. The preoperative tumors were successfully verified morphologically by transthoracic core needle biopsy under CT control in 27.3% of patients. Surgical approaches were either posterolateral thoracotomy or videothoracoscopy. The follow-up median was 45 months (range 1–188 months). Results: Twenty tumors were surgically removed radically, two tumors were found to be unresectable due to the considerable tumor size. From histological point of view 81.8% of tumors were SFT with low malignant potential, 18.2% of tumors with high malignant potential. Despite the radical extirpation of the SFT, it relapsed in two patients. Conclusion: The gold standard of SFT treatment is radical surgical removal; however, patients at risk of recurrence require additional follow-ups. The results of adjuvant therapy in recurrent and malignant forms of SFTs are the subject of discussion and further study. PMID:28049955

Surgical treatment of mitral stenosis (MS) usually consists of open mitral commissurotomy (MC) or percutaneous balloon MC, which require a cardiopulmonary bypass or transseptal approach, respectively. We describe here the first surgical management of congenital MS in a dog using a less invasive procedure, a surgical closed MC under direct echo guidance. A 5-year-old female Cairn terrier was referred for ascites, weakness, and marked exercise intolerance for 2 months, which was refractory to medical treatment. Diagnosis of severe MS associated with atrial fibrillation (AF) was confirmed by echo-Doppler examination and electrocardiography. Poor response to medical treatment suggested a corrective procedure on the valve was indicated. However, due to the cost and high mortality rate associated with cardiopulmonary bypass, a hybrid MC was recommended. A standard left intercostal thoracotomy was performed and three balloon valvuloplasty catheters of differing diameters were sequentially inserted through the left atrium under direct echo guidance. Transesophageal echocardiography revealed a 62% reduction in the pressure half-time compared to the pre-procedure. Thirteen months after surgery the dog is still doing well with resolution of ascites and a marked improvement of most echo-Doppler variables. Copyright © 2011 Elsevier B.V. All rights reserved.

[Diagnosis and Treatment of Hemothorax].

Most cases of hemothorax are related to blunt trauma, procedures, neoplasm such as schwanommas of von-Recklinghausen disease and soft-tissue tumors, and vascular ruptures. Spontaneous pneumothorax is also a caused of spontaneous hemothorax. Hemothorax may result in respiratory distress, respiratory failure, retained clot, fibrothorax, empyema and extended hospitalization. We should attempt to clear the chest cavity as early in the hospital course as the patient's physiology will allow. The management of hemothorax has been a complex problem since it was 1st described over 200 years ago. Traditionally, lrage hemothorax is treated primarily by closed thoracic drainage by inserting a large-caliber chest tube in stable patients. In hemodynamically unstable patients with more than 1,000 ml of blood drainage from the initial thoracotomy or ongoing blood losses of more than 100 to 200 ml/h, an early surgical approach with ongoing resuscitation is needed. Video-assisted thoracoscopic surgery (VATS), minimally invasive surgery, grows and finds new applications for the patients with hemothorax as both diagnostic and therapeutic interventions recently. VATS is an accurate, safe, and reliable operative therapy in the 5-day post event window, but there is a decreasing success rate after this time period.

Accidental entrapment of an endo-bronchial blocker tip by a surgical stapler during selective ventilation for lung lobectomy in a dog.

To describe the use of an endobronchial blocker (EBB) and to perform selective ventilation during pulmonary lobe resection via thoracotomy in a dog and report its accidental stapling in the resection site. Clinical case report. One female dog with a suspected abscess or neoplasia of the right caudal pulmonary lobe. One-lung ventilation was performed using a wire-guided EBB to seal the contaminated parenchyma and facilitate surgical access. The affected lung parenchyma was resected and the resection site was closed with staples. Lobar resection was performed successfully, but the loop of the EBB guide wire was inadvertently entrapped in the staple line of the lobectomy. Staples were removed to release the wire loop, and the resulting air leak caused loss of ventilation control until the parenchyma was re-sealed. We recommend removing the wire guide associate with the EBB after successful lung separation to avoid accidents that could have life-threatening consequences if not recognized. One-lung ventilation is useful to isolate healthy parenchyma from diseased parenchyma during lobectomy. Anesthesiologists and surgeons need to be aware of the potential complications associated with use of EBB.

This syndrome complex includes congenital bicuspid aortic valve, Seller's grade II aortic regurgitation, juxta- subclavian coarctation, stenosis of ostium of left subclavian artery and ruptured sinus of Valsalva aneurysm without any evidence of infective endocarditis. This type of constellation is extremely rare. Neither coarctation of aorta with left subclavian artery stenosis nor the rupture of sinus Valsalva had a favorable pathology for percutaneus intervention. Taking account into morbidity associated with repeated surgery and anesthesia patient underwent a single stage surgical repair of both the defects by two surgical incisions. The approaches include median sternotomy for rupture of sinus of Valsalva and lateral thoracotomy for coarctation with left subclavian artery stenosis. The surgery was uneventful. After three months follow up echocardiography showed mild residual gradient across the repaired coarctation segment, mild aortic regurgitation and no residual left to right shunt. This patient is under follow up. This is an extremely rare case of single stage successful repair of coarctation and rupture of sinus of Valsalva associated with congenital bicuspid aortic valve.

Primary spontaneous pneumothorax (PSP) affects young healthy people with a significant recurrence rate. Recent advances in treatment have been variably implemented in clinical practice. This statement reviews the latest developments and concepts to improve clinical management and stimulate further research.The European Respiratory Society's Scientific Committee established a multidisciplinary team of pulmonologists and surgeons to produce a comprehensive review of available scientific evidence.Smoking remains the main risk factor of PSP. Routine smoking cessation is advised. More prospective data are required to better define the PSP population and incidence of recurrence. In first episodes of PSP, treatment approach is driven by symptoms rather than PSP size. The role of bullae rupture as the cause of air leakage remains unclear, implying that any treatment of PSP recurrence includes pleurodesis. Talc poudrage pleurodesis by thoracoscopy is safe, provided calibrated talc is available. Video-assisted thoracic surgery is preferred to thoracotomy as a surgical approach.In first episodes of PSP, aspiration is required only in symptomatic patients. After a persistent or recurrent PSP, definitive treatment including pleurodesis is undertaken. Future randomised controlled trials comparing different strategies are required. Copyright ©ERS 2015.

Quality of Life after Open or Minimally Invasive Esophagectomy in Patients With Esophageal Cancer-A Systematic Review.

Although esophageal cancer is rare in the United States, 5-year survival and quality of life (QoL) are poor following esophageal cancer surgery. Although esophageal cancer has been surgically treated with esophagectomy through thoracotomy, an open procedure, minimally invasive surgical procedures have been recently introduced to decrease the risk of complications and improve QoL after surgery. The current study is a systematic review of the published literature to assess differences in QoL after traditional (open) or minimally invasive esophagectomy. We hypothesized that QoL is consistently better in patients treated with minimally invasive surgery than in those treated with a more traditional and invasive approach. Although global health, social function, and emotional function improved more commonly after minimally invasive surgery compared with open surgery, physical function and role function, as well as symptoms including choking, dysphagia, eating problems, and trouble swallowing saliva, declined for both surgery types. Cognitive function was equivocal across both groups. The potential small benefits in global and mental health status among those who experience minimally invasive surgery should be considered with caution given the possibility of publication and selection bias.

Background and aim: This study has been conducted to determine the clinical presentations and surgical outcome of patients with OA admitted in a tertiary level hospital in Bangladesh. A prospective analysis was conducted for 32 patients with confirmed OA between July 2007 and June 2015. Of them surgical correction was done in 25 cases. The other 7, in whom surgery could not be done, were excluded from the study. Of the 25 cases, that had been operated, 15 were full term and 52% were more than 48 hours old. Type-C OA with TOF was the commonest type (96%). 24 cases were operated through Right Thoracotomy. Of them 52% were done by Single Lung (left) ventilation. 'Division of the fistula' with 'end to end anastomosis' was done in all of them. Only 1 patient had a Gastric pull up surgery. Of the 25 cases, 16 survived (64%). In follow up all the patients were found thriving and showed no problem in swallowing. Our study which shows 64% survival is a great achievement for us but not satisfactory in international standard. However, the experience and encouragement that we are gathering, will guide us to achieve better result in near future.

A successful cephalosomatic anastomosis ("head transplant") requires, among others, the ability to control long-term immune rejection and avoidance of ischemic events during the head transference phase. We developed a bicephalic model of head transplantation to study these aspects. The thoracic aorta and superior vena cava of a donor rat were anastomosed with the carotid artery and extracorporeal veins of a recipient rat by vascular grafts. Before thoracotomy in the donor rat, the axillary artery and vein of the donor were connected to the carotid and the extracranial vein of the third rat through a silicone tube. The silicone tube was passed through a peristaltic pump to ensure donor brain tissue blood supply. There is no ischemia reperfusion injury in donor brain tissue analyzed by electroencephalogram. Postoperative donor has pain reflex and corneal reflex. Peristaltic pump application can guarantee the blood supply of donor brain tissue per unit time, while the application of temperature change device to the silicone tube can protect the brain tissue hypothermia, postoperative experimental data show that there is no brain tissue ischemia during the whole operation. The application of vascular grafting can also provide the possibility of long-term survival of the model. © 2017 John Wiley & Sons Ltd.

Superior outcomes after video-assisted thoracoscopic surgery (VATS) pulmonary lobectomy have been demonstrated, compared with thoracotomy, for patients affected by early-stage non-small cell lung cancer (NSCLC). However, in an era of rising health care costs and controlled resources, the overall medical cost of surgical procedures is measured by the hospitals' marketing offices. Several factors such as surgical technique, conversion rate, length of stay, post-operative complications occurrence and mainly the introduction of new surgical technologies (disposables and devices) could influence the cost-effectiveness of VATS procedures. However, increased operating room costs are counteracted by shorter hospital stay and reduced ward bed stays providing further resources for other patients. Thus, choosing a surgical approach and assessing whether a specific technique is cost-effective is mandatory for a modern thoracic surgeon to justify its expenses. This review tries to reach a conclusion by comparing all recent studies reporting a cost analysis for VATS lobectomy, especially for new technologies used for VATS lobectomy. Nevertheless, no sufficient evidences are published to assess VATS new technologies sustainability and further cost analyses are necessary before VATS lobectomy expense is deemed justified.

Oncologic considerations in the elderly.

Kamel, Mohamed K; Port, Jeffrey L

2018-02-01

Elderly patients presenting with thoracic malignancies tend to be largely undertreated because of a presumption that this group will incur a high treatment-associated morbidity and mortality. The current review highlights the current practice and recent updates in the surgical management of thoracic malignancies, mainly lung cancer, in the elderly population. Lung resections appears to be relatively safe in the elderly patients presenting with lung cancer. Whenever possible, a lobectomy should be offered to patients with a good performance status who present with early stage disease. However, a limited resection may offer a valuable comparable alternative in patients with advanced comorbidities and borderline pulmonary functions. The use of minimally invasive approaches, namely video-assisted thoracoscopic surgery and robotic surgery are associated with lower morbidity and improved perioperative outcomes compared with the traditional thoracotomy approach and are ideal for the aged. In elderly patients presenting with advanced staged lung cancer, major lung resections following induction therapy, although feasible, should be discussed in a multispecialty tumor board committee. There is growing evidence from the literature that surgical resection is relatively safe in the elderly population. Age by itself should not preclude patients from having curative resection. Resections can be tailored to performance status of the patient.

The benefit and safety of off-pump coronary artery bypass surgery in patients with unstable angina was assessed retrospectively. From February 1996 to October 2001, 5,306 patients underwent multivessel off-pump coronary artery bypass, of whom 920 (17%) had unstable angina. In these 920 patients, ejection fractions ranged from 15% to 70%, 203 (22%) had an ejection fraction of 20%-35%, and 11 (1%) had an ejection fraction < 20%. Triple-vessel disease was present in 625 patients. Preoperative intraaortic balloon pump support was used in 28 patients. Operative approaches included mid sternotomy (86%), lower partial sternotomy (9%), and left anterior thoracotomy (2%). The number of grafts ranged from 1 to 5 with a mean of 2.43 +/- 0.86, and 92.3% of patients received a left internal mammary artery graft. Twenty-two patients need intraoperative intraaortic balloon pumping. Ten patients (1%) suffered perioperative myocardial infarction. The mean hospital stay was 7.8 +/- 4.3 days. Hospital mortality was 2/920 (0.22%). Intraaortic balloon pumping was helpful in these cases of unstable angina refractory to medical therapy. Off-pump coronary artery surgery was found to be safe and beneficial in these patients.

Robotic-assisted endoscopic single-vessel small thoracotomy allows clinicians to perform coronary artery bypass grafting surgery in a minimally invasive manner using the da Vinci Surgical System. Not all patients are suitable for this technique, and the lack of an appropriate method for patient eligibility avoids completion of the procedure robotically. The objective of this study was to develop a patient eligibility method based on the anatomy of the chest of the patient. Preoperative computed tomography thorax scans of 110 patients were analyzed. Two-dimensional measurements taken on the axial images were used with the goal of finding a relation between the anatomy of the patient and the completion of the procedure robotically. Patients with a distance from the left anterior descending coronary artery to the anterior chest wall of smaller than 15 mm have a 20% probability of requiring conversion of the procedure to open surgery. This probability increases if the chest of the patient is very elliptical, having an anterior-posterior dimension of less than 45% of the transverse dimension. The smaller the distance is from the left anterior descending artery to the anterior chest wall, the lower the chances are of completing the procedure robotically.

A 3-mo-old male white Bengal tiger (Panthera tigris) presented with the chief complaint of regurgitation of solid food since weaning at 2 mo of age. Compared with its littermates, the tiger was in poor body condition and weighed only 10.3 kg when its littermates were estimated at 20-25 kg. Thoracic radiographs showed a megaesophagus cranial to the heart base. A contrast esophagram more clearly outlined the megaesophagus, and fluoroscopy demonstrated normal motility of the caudal esophagus. Endoscopic examination revealed a structure coursing dorsally from right to left over the esophagus and a constrictive band on the left of the esophagus at the heart base. Nonselective angiography confirmed the presence of a persistent right aortic arch, as well as an aberrant left subclavian artery. A left fourth intercostal thoracotomy was performed, and the ligamentum arteriosum was double ligated and divided. The left subclavian artery did not cause significant compromise of the esophagus and was not manipulated at surgery. The tiger recovered well from anesthesia and surgery. Solid food was slowly introduced over a 2-mo period without any regurgitation. The cub gained weight rapidly after surgery.

The response of the 2,3-diphosphoglycerate (DPG) levels in the blood and brain tissue to a craniocerebral trauma of varying severity was studied in anaesthetized rats. A trauma producing cerebral contusion was followed within two hours by a highly significant rise in DPG concentration in the blood as compared with the control animals or only mildly traumatized rats. The DPG levels in the brain tissue showed no significant differences. Similar changes in DPG concentration were observed in the blood of patients with craniocerebral injuries. The DPG-mediated increased release of oxygen to the tissues represents a compensatory mechanism and is pathognomic for craniocerebral trauma. Patients undergoing surgery with extracorporeal circulation lack this mechanism for counteracting hypoxaemia; already during thoracotomy the DPG concentration in the blood fell significantly and did not reach its original level until 72 hours after the operation. In stored, ACD stabilized, blood the DPG concentration gradually decreases. Estimations carried out over 28 days showed a continuous statistically significant loss of DPG. After 24 hours the DPG levels in stored blood had already dropped to the lower limits of normal - a fact that has to be taken into account in massive blood transfusions.

Current Status and Future Prospects for Esophageal Cancer Treatment

PubMed Central

Kuwano, Hiroyuki

2016-01-01

The local control effect of esophagectomy with three-field lymph node dissection (3FLD) is reaching its limit pending technical advancement. Minimally invasive esophagectomy (MIE) by thoracotomy is slowly gaining acceptance due to advantages in short-term outcomes. Although the evidence is slowly increasing, MIE is still controversial. Also, the results of treatment by surgery alone are limiting, and multimodality therapy, which includes surgical and non-surgical treatment options including chemotherapy, radiotherapy, and endoscopic treatment, has become the mainstream therapy. Esophagectomy after neoadjuvant chemotherapy (NAC) is the standard treatment for clinical stages II/III (except for T4) esophageal cancer, whereas chemoradiotherapy (CRT) is regarded as the standard treatment for patients who wish to preserve their esophagus, those who refuse surgery, and those with inoperable disease. CRT is also usually selected for clinical stage IV esophageal cancer. On the other hand, with the spread of CRT, salvage esophagectomy has traditionally been recognized as a feasible option; however, many clinicians oppose the use of surgery due to the associated unfavorable morbidity and mortality profile. In the future, the improvement of each treatment result and the establishment of individual strategies are important although esophageal cancer has many treatment options. PMID:28003586

Operative videothoracoscopy in the surgical treatment of penetrating firearms wounds of the chest.

1998-09-01

We prospectively analyzed our experience with operative videothoracoscopy (OVT) performed in a field military hospital in cases of penetrating firearms wounds of the thorax (PFAWT) sustained in Chechnya. From February to April 1996, we treated 206 wounded patients, of whom 37 (18.0%) had sustained chest injuries. PFAWT were present in 23 soldiers, accounting for 62.2% of all chest injuries. Twelve injuries were confined to the thorax, eight patients had associated injuries, and three soldiers had thoracoabdominal injuries. Nineteen patients had pleural drainage performed during medical evacuation. The thoracic injuries were right-sided (17), involved bullets or shell splinters (23); were through and through (16), represented solitary wounds (19), and were associated with internal organ injuries (21). Fifteen patients had indications for OVT when they were delivered from the battle-field 1.5 to 22 hours after injury. All patients manifested signs of hemorrhagic shock and hemodynamic instability. Indications for OVT were ongoing intrapleural bleeding (6), clotted hemothorax (6), or marked air leakage (3) preventing lung inflation with the OP-02 apparatus (field modification). OVT revealed 12 lung wounds, nine of which were multiple wounds, pleural bleeding in 6 patients, clotted hemothorax in 11 patients, and foreign bodies in 5 patients. Two patients underwent thoracotomy, one for suspicion of heart injury and the second because we could not adequately visualize and control bleeding revealed at OVT to be from the intercostal artery in the left costovertebral angle. Eight of 23 patients had no indication for operative videothoracoscopy and were managed with continued pleural aspiration and drug therapy. Wedge resection of the lung using an Endo-GIA-30 stapler was necessary in two patients because of parenchymal destruction and bleeding. Evacuation of clotted blood by fragmentation and aspiration was satisfactory in all cases. Satisfactory manual suturing of selected lung injuries was obtained largely with intracorporeal knot tying. The duration of the procedures ranged from 40 to 90 minutes. No morbidity nor mortality was encountered in patients undergoing OVT. Postoperative pain was minimized by using OVT placement of catheters in the chest wall soft tissue with local administration of 2% Trimecain. Patients were able to stand in 10 to 12 hours and to walk by the end of the first postoperative day. All patients who underwent OVT were evacuated without drains by the third or fourth postoperative day, all tolerating sitting and standing positions. We conclude that early OVT in the military field hospital for continued bleeding, clotted hemothorax, and continued major air leakage has several advantages in military patients with PFAWT: early definition and management of organ injury; identification and control of bleeding in most instances; earlier and more accurate assessment for thoracotomy; vigorous lavage and removal of projectiles such as bone fragments and evacuation of clotted hemothorax; early debridement with suture closure of the thoracic wall canal; and minimal postoperative pain with dramatically reduced suppurative sequelae and bronchopleural fistulae.

Gunshot wounds are rare events in European countries, but stab and impalement injuries occur more frequently and are often spectacular. The aim of the study was to describe several types of penetrating abdomino-thoracic injuries as well as the appropriate surgical interventions, including complex wound management. The representative case series includes four patients with abdomino-thoracic penetrating trauma (two impalements and two stabbings), who were treated in a surgical university hospital (tertiary) centre during a 12-month period. 1. A man was impaled on a steel pipe, which entered the body above the right kidney and behind the liver through the mediastinum via the right thorax, passing the heart and aortic arch up to the left clavicle. The rod was removed via sternotomy and median laparotomy. Only the left subclavian vein required repair. Postoperatively, a residual lesion of the left brachial plexus caused temporary pneumonia. 2. A leg of a collapsing chair drilled into a woman's left foramen obturatorium and exited the body at the right anterior iliac spine. At a regional hospital, the chair leg was removed and the canal caused by gluteal penetration was excised. Exploratory laparotomy revealed peritonitis resulting from a perforated ileum. The injury was repaired with segmental resection and anastomosis. Postoperative right inguinal wound necrosis necessitated excision and vacuum-assisted closure sealing. The patient has residual paresthesia in her left leg resulting from a sacral plexus lesion. 3. During an altercation, a man was stabbed twice in the right thorax. The right pulmonary lobe, the diaphragm, and the liver dome between segment VIII and V were injured. The patient also had a large scalp avulsion at the left and right parietooccipital site and transection of the biceps muscle at the middle third of the right humerus. The chest injuries, approached via right subcostal incision and right anterior thoracotomy were managed with liver packing (two towels, removed after 2 days), suture of the diaphragm, and pleural drainage. 4. A man was stabbed in the left thorax, resulting in pneumothorax and lesions of the diaphragm and left third of the transversal colon, and the neck, resulting in lesions of the pharynx and internal jugular vein. These injuries were approached with left thoracic drainage and suture of the colon and diaphragm lesions. Subsequent right thoracotomy was required to treat right pleural empyema caused by bronchopneumonia as a consequence of blunt thoracic trauma. In addition, the patient required relaparotomy to drain an abscess within the Douglas space and Billroth II gastric resection to control recurrent Forrest-Ia bleeding. Penetrating abdomino-thoracic injuries demand immediate life-saving measures, transfer to a trauma centre, appropriate resuscitative care, prompt diagnosis, and surgical intervention by an interdisciplinary team of abdominal, vascular, and cardiac surgeons. If these measures are provided, outcomes are maximized, mortality is minimized, and permanent damage can be avoided.

Evaluation of the aesthetics of physical methods of euthanasia of anesthetized rats.

Dissection of living brain tissue for in vitro experiments requires the use of a rapid euthanasia method. However, the method must not subject animals to unnecessary pain and must be aesthetically acceptable to experimenters. The purposes of the current study were to assess the aesthetics of 6 euthanasia methods, measure the procedure duration, and evaluate brain for pathology after each procedure. We digitally recorded euthanasia of isoflurane-anesthetized rats by 6 physical methods: anesthetic overdose, cardiac exsanguination, decapitation, closed intrathoracic transection of the great vessels and heart, thoracic percussion, and thoracotomy with rupture of great vessels. Volunteer researchers and animal caretakers watched the video and completed an associated questionnaire. Anesthetic overdose and cardiac exsanguinations were rated most aesthetically pleasing, although these procedures took the longest to complete. In contrast, decapitation and thoracic percussion were the least aesthetically pleasing, but these methods were the quickest. No demographic factor was identified that could predict whether a given euthanasia procedure would be favored for aesthetic reasons, and participants provided a wide variety of rationales for the aesthetic ratings they assigned. Although all of these euthanasia methods meet the criteria of approved methods of euthanasia of anesthetized rats as defined by the AVMA, aesthetic features and the scientific need for rapid euthanasia are both considerations in selecting a method.

Effects of Nitroglycerin on Regional Myocardial Blood Flow in Coronary Artery Disease

Horwitz, Lawrence D.; Gorlin, Richard; Taylor, Warren J.; Kemp, Harvey G.

1971-01-01

Regional myocardial blood flow before and after sublingual nitroglycerin was measured in 10 patients with coronary artery disease. During thoracotomy, 133Xe was injected directly into the subepicardium in diseased regions of the anterior left ventricular wall, and washout rates were recorded with a scintillation counter. All disappearance curves were closely approximated by two exponential decays analyzed as two parallel flow systems by the compartmental method. The appearance of a double exponential decay pattern in diseased regions suggests that the slow phase was associated with collateral blood flow, although nonhomogeneous myocardium-to-blood partition coefficients for xenon cannot be excluded. Nitroglycerin increased the rapid phase flow in 9 of 10 patients and the slow flow in 7 of 10 patients. Average flow increased in 9 of the 10 patients (P < 0.01). Mean rapid phase flow in the control state was 110 ml/100 g per min and after nitroglycerin increased to 132 ml/100 g per min (P < 0.01); slow phase flow increased from 12 ml/100 g per min to 15 ml/100 g per min (P < 0.05). It is concluded that, under these conditions, nitroglycerin improves perfusion in regions of diseased myocardium in patients with coronary artery disease. PMID:4999635

The da Vinci Surgical System has been used in only a few cases for treating mediastinal tumors in Japan. Recently, we used the da Vinci Surgical System for various types of anterior and middle mediastinal tumors in clinical practice. We report our early experience using the da Vinci Surgical System. Seven patients gave written informed consent to undergo robotic surgery for mediastinal tumor dissection using the da Vinci Surgical System. We evaluated the safety and feasibility of this system for the surgical treatment of mediastinal tumors. Two specialists in thoracic surgery who are certified to use the da Vinci S Surgical System and another specialist acted as an assistant performed the tumor dissection. We were able to access difficult-to-reach areas, such as the mediastinum, safely. All the resected tumors were classified as benign tumors histologically. The average da Vinci setting time was 14.0 min, the average working time was 55.7 min, and the average overall operating time was 125.9 min. The learning curve for the da Vinci setup and manipulation time was short. Robotic surgery enables mediastinal tumor dissection in certain cases more safely and easily than conventional video-assisted thoracoscopic surgery and less invasively than open thoracotomy.

To summarize our initial experience in robot-assisted thoracoscopic lobectomy. Methods Five patients underwent lobectomy using da Vinci S HD Surgical System (Intuitive Surgical, Sunnyvale, California). During the operation, we respectively made four ports over chest wall for positioning robotic endoscope, left and right robotic arms and auxiliary instruments without retracting ribs. The procedure followed sequential anatomy as complete video-assisted thoracoscopic surgery lobectomy did, and lymph node dissection followed international standard. All patients successfully underwent complete robot-assisted thoracoscopic lobectomy. Neither additional incisions nor emergent conversion to a thoracotomy happened. Frozen dissection during lobectomy showed non-small-cell lung cancer in four patients, who afterwards underwent systemic lymph node dissection, while the case left was with tuberculoma and didn't undergo lymph node dissection. Recurrent air leak occurred in one case, so chest tube was kept for drainage, and one week later, the patient was extubated due to improvement. All other patients recovered well postoperatively without obvious postoperative complications. Robot-assisted thoracoscopic surgery is feasible with good operability, clear visual field, reliable action and its supriority of trouble free; exquisite operative skills are required to ensure a stable and safe operation; robot-assisted surgery is efficiency and patients recover well postoperatively.

Dirofilaria, visceral larva migrans, and tropical pulmonary eosinophilia.

PubMed

Chitkara, R K; Sarinas, P S

Helminthic infections are prevalent worldwide. The intestinal ascarid, Toxocara, the animal filarial parasite, Dirofilaria, and the human filarial parasite, Wuchereria or Brugia, produce an array of pulmonary disease in humans. Infections are common in temperate, tropical, and subtropical regions of the world. Pulmonary dirofilariasis is essentially an asymptomatic disease. Most cases are diagnosed accidentally after thoracotomy for a solitary pulmonary nodule presumed to be lung cancer. Clinical manifestations of toxocariasis or visceral larva migrans (VLM) are the result of allergic and inflammatory responses of the host, and manifest with airway reactivity, acute pneumonia, and persistent eosinophilia. VLM is a self-limited disease and specific treatment is rarely necessary. In acute cases, a short course of steroids reduces morbidity and mortality but preventive measures are more important in curbing toxocara infection. Tropical pulmonary eosinophilia (TPE) is the result of immunologic hyperresponsiveness to the human filarial antigen and eosinophils play a crucial role in its pathogenesis. Airway hyperreactivity, extreme eosinophilia, and pulmonary physiologic impairment are the characteristic features. Treatment of TPE with diethylcarbamazine results in dramatic amelioration of symptoms. However, low grade inflammation persists in a significant number of patients and can lead to chronic interstitial lung disease. Mass treatment of patients in certain endemic areas has been effective in eliminating TPE.

Thoracoscopic esophagomyotomy for achalasia: maximum gain, minimal pain.

Maher, J W

1997-10-01

Achalasia can be effectively treated by either hydrostatic balloon dilatation or transthoracic modified Heller myotomy. The purpose of this study was to determine whether thoracoscopic methods could be used to achieve surgical results equal to the transthoracic approach with less pain. Twenty-one patients (10 men, 11 women; median age 42 years) had the diagnosis of achalasia confirmed by manometry, radiography, and endoscopy. All had dysphagia; five had weight loss. Median duration of symptoms was 12 months (range: 1 to 360 months). Eleven patients had undergone previous unsuccessful hydrostatic dilatation. Mean esophageal diameter was 5.5 +/- 2.2 cm. All patients underwent attempted modified Heller myotomy through a left thoracoscopic approach. Three patients required conversion to thoracotomy. The myotomy was extended < 1 cm past the squamocolumnar junction. There was one intraoperative perforation and no postoperative complications. All patients were begun on a regular diet on the first postoperative morning. Median length of stay was 2 days, Median follow-up was 22 months (range: 1 to 52 months). Sixteen patients (80%) had excellent relief of their dysphagia. Two patients (10%) had good relief, and two patients had only a fair result, although even they claim to be much improved. Thoracoscopic Heller myotomy reproduces the superior results of open esophagomyotomy with a reduced hospitalization and reduced incisional pain and disability.

Birt-Hogg-Dubé syndrome: a literature review and case study of a Chinese woman presenting a novel FLCN mutation.

The Birt-Hogg-Dubé (BHD) syndrome is a very rare autosomal dominant form of genodermatosis caused by germline mutations in the folliculin (FLCN) gene, which is mapped to the p11.2 region in chromosome 17. BHD commonly presents cutaneous fibrofolliculomas, pulmonary cysts, renal cell carcinoma, and recurrent pneumothoraxes. The disease is easily ignored or misdiagnosed as pneumothorax, pulmonary lymphangiomyomatosis (LAM), or emphysema. Follow-up and guidelines for managing recurrent pneumothoraxes in these patients are lacking. We reported the case of a 56-year-old Chinese woman who presented skin lesions, multiple lung bubblae, recurrent pneumothoraxes, thyroid nodules, and pulmonary inflammatory pseudotumors (PITs). The patient had a family history of pneumothoraxes and renal tumor. The BHD diagnosis was confirmed by genetic testing, which revealed a novel FLCN mutation in exon 14. Furthermore, the patient underwent a bullectomy because of recurrent pneumothorax 6 years ago. To our knowledge, the novel mutation in exon 14 and the manifestation of PIT in the present case have never been reported for BHD. The patient underwent a bullectomy previously with no relapse at the last follow-up before the preparation of this report, thereby suggesting that thoracotomy with bullectomy may be a possible therapeutic approach for some BHD patients with recurrent pneumothorax.

In this study, the therapeutic use of pacing pulmonary artery catheters in association with minimally invasive cardiac surgery was evaluated. A retrospective study. A single institutional university hospital. Two hundred twenty-four consecutive patients undergoing minimally invasive cardiac surgery through a small (5-cm) right anterolateral thoracotomy using fibrillatory arrest without aortic cross-clamping. Two hundred eighteen patients underwent mitral valve surgery (97%) alone or in combination with other procedures. Six patients underwent other cardiac operations. In all patients, the pacing pulmonary artery catheter was used intraoperatively to induce ventricular fibrillation during the cooling period, and in the postoperative period it also was used in 37 (17%) patients who needed to be paced, mainly for bradyarrhythmias (51%). There were no complications related to the insertion of the catheters. Six (3%) patients experienced a loss of pacing capture, and 2 (1%) experienced another complication requiring the surgical removal of the catheter. Seven (3%) patients needed postoperative implantation of a permanent pacemaker. In combination with minimally invasive cardiac surgery, pacing pulmonary artery catheters were therapeutically useful to induce ventricular fibrillatory arrest intraoperatively and for obtaining pacing capability in the postoperative period. Their use was associated with a low number of complications. Copyright 2010 Elsevier Inc. All rights reserved.

Single paracostal approach to thoracic duct and cisterna chyli: experimental study and case series.

Staiger, Benjamin A; Stanley, Bryden J; McAnulty, Jonathan F

2011-10-01

To-determine the feasibility of a single paracostal abdominal approach for thoracic duct ligation (TDL) and cisterna chyli ablation (CCA) in dogs with chylothorax. Observational study and prospective case series. Normal dogs (n = 5) and dogs with chylothorax (n = 8). A single paracostal approach with transdiaphragmatic extension for TDL and CCA was developed experimentally (n = 5) and used in 8 clinical cases with subtotal pericardectomy (SPE) performed in 4 dogs. Surgery time, complications, hospitalization time, outcome, and follow-up of clinical cases were recorded. Exposure of relevant anatomy was excellent; vital lymphatic staining facilitated identification of lymphatic structures. In clinical cases, mean surgery time for TDL + CCA was 136 minutes. Mean hospitalization time was 3.1 days. Seven of 8 cases survived, with 1 dog dying of heart failure shortly after discharge. One dog required a second (left) paracostal approach to ligate 2 more lymphatic vessels. On follow-up (median, 7 months; range, 2-20 months), there was complete resolution of chylothorax in 6 dogs. A single paracostal approach provides excellent exposure of cisterna chyli, caudal thoracic duct, and intestinal lymphatics. This approach eliminates the need for repositioning during combined TDL + CCA procedures and avoids an intercostal thoracotomy. © Copyright 2011 by The American College of Veterinary Surgeons.

Major lung resection using minimally invasive techniques - video-assisted thoracoscopic surgery (VATS) - was first described 20 years ago. However, its development has been slow in many countries because the value of this approach has been questioned. Different techniques and definitions of VATS are used and this can be confusing for physicians and surgeons. The benefit of minimally invasive thoracic surgery was not always apparent, while many surgeons pointed to suboptimal operative outcomes. Recently, technological advances (radiology, full HD monitor and new stapler devices) have improved VATS outcomes. The objectives of this review are to emphasize the accepted definition of VATS resection, outline the different techniques developed and their results including morbidity and mortality compared to conventional approaches. Minimally invasive thoracic surgery has not been proven to give superior survival (level one evidence) compared to thoracotomy. A slight advantage has been demonstrated for short-term outcomes. VATS is not a surgical revolution but rather an evolution of surgery. It should be considered together with the new medical environment including stereotactic radiotherapy and radiofrequency. VATS seems to be more accurate in the treatment of small lung lesions diagnosed with screening CT scan. In the academic field, VATS allows easier teaching and diffusion of techniques.

Background: COPD is an inflammatory disorder characterised by chronic airflow limitation, but the extent to which airway inflammation is related to functional abnormalities is still uncertain. The interaction between inflammatory cells and airway smooth muscle may have a crucial role. Methods: To investigate the microlocalisation of inflammatory cells within the airway smooth muscle in COPD, surgical specimens obtained from 26 subjects undergoing thoracotomy (eight smokers with COPD, 10 smokers with normal lung function, and eight non-smoking controls) were examined. Immunohistochemical analysis was used to quantify the number of neutrophils, macrophages, mast cells, CD4+ and CD8+ cells localised within the smooth muscle of peripheral airways. Results: Smokers with COPD had an increased number of neutrophils and CD8+ cells in the airway smooth muscle compared with non-smokers. Smokers with normal lung function also had a neutrophilic infiltration in the airway smooth muscle, but to a lesser extent. When all the subjects were analysed as one group, neutrophilic infiltration was inversely related to forced expiratory volume in 1 second (% predicted). Conclusions: Microlocalisation of neutrophils and CD8+ cells in the airway smooth muscle in smokers with COPD suggests a possible role for these cells in the pathogenesis of smoking induced airflow limitation.

To study the effect of coronary sinus (CS) occlusion on normal hearts and hearts with structural disease. We included 32 dogs, divided into 4 groups: (1) CS ligation (CSL): subjected to CSL; (2) control group: no intervention; (3) MI-CSL group: subjected to myocardial infarction (MI) induction followed by CSL after 1 week; and (4) MI-control group: subjected to MI induction, then open thoracotomy after 1 week without CSL. Electrocardiography, echocardiography, histopathology, and immunohistochemistry were done before and after CSL. In CSL group, there were no significant electrocardiographic or echocardiographic changes after CSL, although there was interstitial oedema that decreased after 1 week with the appearance of Thebesian vessels and positive staining for vascular endothelial growth factor. In MI-CSL group, there was significant increase in left ventricular (LV) end-systolic diameter (P = 02), decrease in LV fractional shortening (P = 0.0001), and LV ejection fraction (P = 0.002) in comparison with MI-control group, associated with severe myocardial degeneration. Acute CS occlusion could be compensated in normal hearts, but may be detrimental in the presence of structural heart disease. Published on behalf of the European Society of Cardiology.

Chest physiotherapy with positive expiratory pressure breathing after abdominal and thoracic surgery: a systematic review.

PubMed

Orman, J; Westerdahl, E

2010-03-01

A variety of chest physiotherapy techniques are used following abdominal and thoracic surgery to prevent or reduce post-operative complications. Breathing techniques with a positive expiratory pressure (PEP) are used to increase airway pressure and improve pulmonary function. No systematic review of the effects of PEP in surgery patients has been performed previously. The purpose of this systematic review was to determine the effect of PEP breathing after an open upper abdominal or thoracic surgery. A literature search of randomised-controlled trials (RCT) was performed in five databases. The trials included were systematically reviewed by two independent observers and critically assessed for methodological quality. We selected six RCT evaluating the PEP technique performed with a mechanical device in spontaneously breathing adult patients after abdominal or thoracic surgery via thoracotomy. The methodological quality score varied between 4 and 6 on the Physiotherapy Evidence Database score. The studies were published between 1979 and 1993. Only one of the included trials showed any positive effects of PEP compared to other breathing techniques. Today, there is scarce scientific evidence that PEP treatment is better than other physiotherapy breathing techniques in patients undergoing abdominal or thoracic surgery. There is a lack of studies investigating the effect of PEP over placebo or no physiotherapy treatment.

In a retrospective study, the authors analyzed the surgical approach to the intrathoracic goiter to avoid sternotomy or thoracotomy. We selected 70 intrathoracic cases of multinodular goiter out of 988 cases of thyroidectomy and compared them with cervical goiter cases. Surgical technique, results, and postsurgical complications were assessed. The analyzed cases presented the retrosternal goiter (n = 53; 75.7%), the retrotracheal goiter (n = 9; 12.8%), and the retroesophageal goiter (n = 8; 11.4%). Complaining of chest pressure or discomfort was specific for intrathoracic cases (50%; 35 of 70). All goiters except one were removed via cervical incision. The surgeons used head reclination and isthmus dissection when removing sizable goiters. Mean weight of goiters was 180 g. The recurrent laryngeal nerve was more often temporarily damaged in intrathoracic cases in comparison with cervical cases (4.3% vs. 2.8%, P  = .04), but the difference in permanent injury was less significant ( P  = .09). The incidence of temporary hypoparathyroidism was significantly higher in intrathoracic cases ( P  = .01). In cases of multinodular goiter the goiters of various extensions can be successfully removed via the cervical incision in most of the cases even if they occupy the retrosternal, retrotracheal, or retroesophageal position. The transthoracic approaches and sternotomy might be justified in malignant cases. 4.

Background. The management and outcomes of occult hemopneumothorax in blunt trauma patients who required mechanical ventilation are not well studied. We aimed to study patients with occult hemopneumothorax on mechanical ventilation who could be carefully managed without tube thoracostomy. Methods. Chest trauma patients with occult hemopneumothorax who were on mechanical ventilation were prospectively evaluated. The presence of hemopneumothorax was confirmed by CT scanning. Hospital length of stay, complications, and outcome were recorded. Results. A total of 56 chest trauma patients with occult hemopneumothorax who were on ventilatory support were included with a mean age of 36 ± 13 years. Hemopneumothorax was managed conservatively in 72% cases and 28% underwent tube thoracostomy as indicated. 29% of patients developed pneumonia, 16% had Acute Respiratory Distress Syndrome (ARDS), and 7% died. Thickness of hemothorax, duration of mechanical ventilation, and development of ARDS were significantly associated with tube thoracostomy in comparison to no-chest tube group. Conclusions. The majority of occult hemopneumothorax can be carefully managed without tube thoracostomy in patients who required positive pressure ventilation. Tube thoracotomy could be restricted to those who had evidence of increase in the size of the hemothorax or pneumothorax on follow-up chest radiographs or developed respiratory compromise.

Abstract Postoperative chylothorax is a rare but well-known complication of general thoracic surgery. Medical treatment of chylothorax was reported in the past, but there is still considerable controversy on the appropriate management strategies. Two patients with esophageal cancer underwent esophagectomy, 2-field lymph node dissection, and resection of thoracic duct together with ileocolic reconstruction via the retrosternal route at our hospital. Chylothorax developed on the 32nd postoperative day (POD) in 1 patient and the 12th POD in the other, manifesting as a change in the character of thoracic drainage to turbid white. Both were immediately started on octreotide (300 μg/ day) and etilefrine (120 mg/day). When the amount of pleural effusion decreased to <50 mL/day, we performed pleurodesis with Picibanil (OK432). Thereafter, the patients gradually made satisfactory progress and resumed oral food intake, and the thoracotomy tubes were eventually removed. They have remained recurrence-free at the time of writing. In this report, we demonstrated the clinical efficacy of etilefrine for the management of postesophagectomy chylothorax. New medical treatment options for this condition are now broad and the usefulness of combined therapy consisting of a sclerosing agent, etilefrine, and octreotide is underscored, regardless of the status of the thoracic duct.

(1) There is lack of epidemiological data on penetrating trauma in European countries. (2) In Finland most acts of violence are performed under the influence of alcohol. The aim of this study was to determine the incidence and types of injury, treatment and survival of patients with penetrating injuries to the thorax and abdomen. This study includes two trauma centers with combined catchment area of approximately 720,000 patients. Patients were identified from patient records using ICD-10 codes. Patients were predominantly young males and they were stab victims. The average yearly incidence for penetrating trauma was 0.9/100,000 inhabitants. Thirteen percent of patients admitted gave a negative toxicology screen or breathalyzer test for alcohol. Twenty two percent of wounds were self-inflicted. Fifty five percent of patients received a chest tube and 30 patients (23%) underwent emergent thoracotomy after sustaining critical injury to the thorax. A considerable proportion (12%) of the study group also later died due to alcohol and/or violence, highlighting the psychosocial co-morbidity among penetrating trauma victims. Chest tube insertion is a skill to be mastered by any on-call physician. This simple procedure can be potentially life-saving. There is also a call for assessment of psychosocial well-being among penetrating trauma victims.

Background: Although right parasternal approach (RPA) decreases the incidence of mediastinal infection, this approach is associated with lung hernia and flail chest. Our RPA employs thoracotomy with bending rib cartilages and wound closure performed by repositioning the ribs with underlying sheet reinforcement. Methods: We evaluated 16 patients who underwent aortic valve replacement via the RPA from January 2010 to August 2013. We compared outcomes of 15 male patients had the RPA with 30 male patients had full median sternotomy. Results: One patient with a history of radical breast cancer treatment underwent RPA with concomitant right coronary artery bypass grafting. No hospital deaths occurred. Four patients developed hospital-associated morbidity (re-exploration for bleeding, prolonged ventilation, cardiac tamponade, and perioperative myocardial infarction). There were no conversions to full median sternotomy, mediastinal infections, and lung hernias. Preoperative computed tomography showed that the distance from the right sternal border to the aortic root was significantly associated with operation times. With RPA, there was no significant difference in outcomes, despite significantly longer operation times compared with full median sternotomy. Conclusion: Our RPA provides satisfactory outcomes without lung hernia, especially in patients unsuitable for sternotomy. Preoperative computed tomography is useful for identifying appropriate candidates for the RPA. PMID:25167927

Posterior reversible encephalopathy syndrome following a thoracic discectomy-induced dural leak: case report.

PubMed

Shields, Lisa B E; Johnson, John R; Shields, Christopher B

2016-11-01

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome characterized by headaches, altered mental status, seizures, and visual disturbances. Classic MRI findings include white matter changes of the parieto-occipital regions. This syndrome has been encountered in myriad medical illnesses, including hypertension, preeclampsia/eclampsia, and immunosuppressive conditions. While the pathogenesis of the disorder is unclear, vasoconstriction and hypoperfusion leading to brain ischemia and vasogenic edema have been implicated as potential mechanisms. The authors present, to the best of their knowledge, the first case of PRES following a thoracic spinal surgery-induced dural leak noted on resection of the fifth rib during a thoracotomy for a T4-5 discectomy. Brain MRI revealed large areas of increased FLAIR and T2 hyperintensity in the superior posterior frontal lobes, superior and medial parietal lobes, and bilateral occipital lobes. Following repair of the CSF leak, the patient's symptoms resolved. Spinal surgeons should be alert to the potentially life-threatening condition of PRES, especially in a hypertensive patient who experiences surgery-induced dural leakage. The development of a severe positional headache with neurological signs is a red flag that suggests the presence of PRES. Prompt attention to the diagnosis and treatment of this condition by repairing the dural leak via surgery or expeditious blood patch increases the likelihood of a favorable outcome.

Despite significant advances in the treatment of thoracic infections, complex lung abscess remains a problem in modern thoracic surgery. We describe the novel application of vacuum-assisted closure for the treatment of a lung abscess. The technical details and preliminary results are reported. After the initial failed conservative treatment of an abscess, minimally invasive surgical intervention was performed with vacuum-assisted closure. The vacuum sponges were inserted in the abscess cavity at the most proximal point to the pleural surface. The intercostal space of the chest wall above the entering place was secured by a soft tissue retractor. The level of suction was initially set to 100 mm Hg, with a maximum suction of 125 mm Hg. The sponge was changed once on the 3rd postoperative day. The abscess cavity was rapidly cleaned and decreased in size. The mini-thoracotomy could be closed on the 9th postoperative day. Closure of the cavity was simple, without any short- or long-term treatment failure. This technique reduced the trauma associated with the procedure. The patient was discharged on the 11th postoperative day. Vacuum-assisted closure systems should be considered for widespread use as an alternative option for the treatment of complicated pulmonary abscess in elderly, debilitated, immunocompromised patients after failed conservative treatment.

Differentiation of Lung Cancer, Empyema, and Abscess Through the Investigation of a Dry Cough.

Urso, Brittany; Michaels, Scott

An acute dry cough results commonly from bronchitis or pneumonia. When a patient presents with signs of infection, respiratory crackles, and a positive chest radiograph, the diagnosis of pneumonia is more common. Antibiotic failure in a patient being treated for community-acquired pneumonia requires further investigation through chest computed tomography. If a lung mass is found on chest computed tomography, lung empyema, abscess, and cancer need to be included on the differential and managed aggressively. This report describes a 55-year-old Caucasian male, with a history of obesity, recovered alcoholism, hypercholesterolemia, and hypertension, presenting with an acute dry cough in the primary care setting. The patient developed signs of infection and was found to have a lung mass on chest computed tomography. Treatment with piperacillin-tazobactam and chest tube placement did not resolve the mass, so treatment with thoracotomy and lobectomy was required. It was determined through surgical investigation that the patient, despite having no risk factors, developed a lung abscess. Lung abscesses rarely form in healthy middle-aged individuals making it an unlikely cause of the patient's presenting symptom, dry cough. The patient cleared his infection with proper management and only suffered minor complications of mild pneumoperitoneum and pneumothorax during his hospitalization.

The mortality and morbidity of chronic obstructive pulmonary disease are high. However, no radical therapy has been developed to date. The purpose of this study was to evaluate whether fetal mouse lung tissue can grow and differentiate in the emphysematous lung. Fetal lung tissue from green fluorescent protein C57BL/6 mice at 16 days' gestation was used as donor material. Twelve-month-old pallid mice were used as recipients. Donor lungs were cut into small pieces and implanted into the recipient left lung by performing thoracotomy under anesthesia. The recipient mice were sacrificed at day 7, 14, and 28 after implantation and used for histological examination. Well-developed spontaneous pulmonary emphysema was seen in 12-month-old pallid mice. Smooth and continuous connection between implanted fetal lung tissue and recipient lung was recognized. Air space expansion and donor tissue differentiation were observed over time. We could clearly distinguish the border zones between injected tissue and native tissue by the green fluorescence of grafts. Fetal mouse lung fragments survived and differentiated in the emphysematous lung of pallid mice. Implantation of fetal lung tissue in pallid mice might lead to further lung regeneration research from the perspective of respiratory and exercise function. J. Med.

Eleven patients with dysphagia caused by severe esophageal stricture (length 2 to 10 cm) resulting from reflux esophagitis were treated with fibroendoscopic dilation (Eder-Puestow) and Roux-en-Y partial gastrectomy with vagotomy during 10 years (1979 to 1988). There was no operative mortality, but complications developed in three patients: One patient had a mediastinal abscess demanding thoracotomy as a result of esophageal perforation after dilatation; one had postoperative pneumonia; and one patient had ileus. After a mean follow-up of 4 years (range 1 to 10 years) esophagitis healed in all cases, as judged by endoscopy. Eight patients were asymptomatic, but three had slight transient dysphagia. Postoperatively one to eight dilations (average three to four) were needed to relieve dysphagia in the first postoperative year, but later the stricture healed in every case. Postoperative pH measurement was performed in six latest patients and showed complete absence of reflux in all cases. It is concluded that Roux-en-Y partial gastrectomy with vagotomy and endoscopic dilation is an effective, simple, and safe procedure in the management of severe peptic esophageal (acid or alkaline esophagitis) stricture. However, occasional postoperative dilations at the outpatient clinic are often needed in severe cases in the first postoperative year.

Summary Background We performed this observational prospective study to evaluate the results of the application of a diagnostic and therapeutic algorithm for complicated parapneumonic pleural effusion (CPPE) and pleural parapneumonic empyema (PPE). Material/Methods From 2001 to 2007, 210 patients with CPPE and PPE were confirmed through thoracocentesis and treated with pleural drainage tubes (PD), fibrinolytic treatment or surgical intervention (videothoracoscopy and posterolateral thoracotomy). Patients were divided into 3 groups: I (PD); II (PD and fibrinolytic treatment); IIIa (surgery after PD and fibrinolysis), and IIIb (direct surgery). The statistical study was done by variance analysis (ANOVA), χ 2 and Fisher exact test. Results The presence of alcohol or drug consumption, smoking and chronic obstructive pulmonary disease (COPD) were strongly associated with a great necessity for surgical treatment. The IIIa group was associated with increased drainage time, length of stay and complications. No mortality was observed. The selective use of PD and intrapleural fibrinolysis makes surgery unnecessary in more than 75% of cases. Conclusions The selective use of PD and fibrinolysis avoids surgery in more than 75% of cases. However, patients who require surgery have more complications, longer hospital stay, and more days on PD and they are more likely to require admittance to the Intensive Care Unit. PMID:22739734

House paints, the industrial products of toxic chemicals are known to be linked with severe respiratory disturbances especially in inadequately ventilated places. In this study, we aimed to report a biopsy-proven case of extrinsic allergic alveolitis (EAA) who presented with nonspecific respiratory symptoms 1 month after having her whole house interior painted. At CT scanning, we observed the ground glass opacities and the micronodular pattern typical for EAA and also a solid, consolidative lung area, highly suggestive of malignancy. The case initially was misinterpreted as a malignant tumor both radiologically and cytologically at CT-guided transthoracic fine needle aspiration biopsy. The final pathologic diagnosis was given as EAA on frozen section performed during thoracotomy operation. The patient received short-term steroid treatment and has been doing well for the last 7 months after her operation. As a conclusion, when assessing a cytologic material from a patient who has got a solid lung mass and also a history of chemical dye exposure, consolidative mass formation which is a rare form of EAA should always be kept in mind. Another final point is that the appropriate ventilation should be achieved if the exposure with the house paint chemicals is inevitable. Copyright © 2011 Wiley Periodicals, Inc.

Missile cardiovascular injuries have taken an epidemic proportion in Kashmir valley since the eruption of militancy in 1990. Present study was undertaken to analyse the pattern, presentation and management of missile cardiovascular injuries. Three hundred and eighty-six patients with missile cardiovascular injuries since Jan 1996 to Oct 2008 were studied retrospectively. All patients of cardiovascular injuries due to causes other than missiles were excluded from the study. All patients of missile cardiac injuries were treated by primary cardiorrhaphy. Right ventricle was the most commonly affected chamber. Left anterior thoracotomy was most common approach used. Most of the patients of missile vascular group were treated by reverse saphenous vein graft or end-to-end anastomosis. Most common complication was wound infection (20.83%) followed by graft occlusion (1.94%) in missile vascular group. Amputation rate was 4.66%. Amputation rate was higher in patients with delay of >6 hours and associated fractures. Missile cardiac injuries should be operated early without wasting time for investigations. Clinical status at arrival, time interval till management, nature of injury and associated injuries, tell upon the mortality. Missile vascular injury needs prompt resuscitation and revascularization at the earliest. Time interval till revascularization and associated fractures has a bearing on mortality and morbidity.

The treatment of long-gap esophageal atresia remains an issue for pediatric surgeons. Many techniques for treating long-gap esophageal atresia have been proposed, but the optimal method has not been established. The thoracoscopic esophageal elongation technique has recently been developed. We previously reported a case in which two-stage thoracoscopic repair was performed using internal esophageal traction without esophageal tearing, and we retrospectively reviewed the outcomes of this procedure in this study. Five patients underwent thoracoscopic treatment involving internal esophageal traction for esophageal atresia involving a long gap or vascular ring over a 5-year period. Between November 2010 and November 2015, 5 patients were treated with thoracoscopic traction. All of these patients successfully underwent thoracoscopic-delayed primary anastomosis. Conversion to open thoracotomy was not required in any case. The postoperative complications experienced by the patients included minor anastomotic leakage in 2 cases, anastomotic stenosis in 1 case, gastroesophageal reflux (GER) in 4 cases, and a hiatal hernia in 1 case. None of the patients died. Two-stage thoracoscopic repair for esophageal atresia involving a long gap or vascular ring is a safe and feasible procedure; however, we must develop methods for treating minor anastomotic complications and GER due to esophageal traction in future.

The purpose of this study was to examine the longitudinal effect of gradual coronary occlusion on regional myocardial metabolism of 15-p-123I-iodophenylpentadecanoic acid [( 123I]IPPA). Adult dogs were imaged using [123I]IPPA and planar gamma imaging. A thoracotomy was performed and an ameroid constrictor of appropriate size permanently positioned on the left anterior descending coronary artery. The dogs were imaged after injection of 3-5 mCi [123I]IPPA at various times over a 2-week period. With imaging on days 7 and 14, the dogs were paced at a rate of 185. Time-activity curves were generated and t1/2 values calculated using monoexponential curve fitting. Results indicate a significant increase in t1/2 between control and 14 days after surgery in the apical wall (29 +/- 7 to 53 +/- 18 min; P less than 0.05). Although there was also an increased t1/2 in the lateral wall, this was not significant (27 +/- 8 to 78 +/- 99 min; P greater than 0.05). There was no significant change in t1/2 in the septal wall (27 +/- 9 to 33 +/- 8 min; P greater than 0.05). We conclude that [123I]IPPA is a useful indicator of developing myocardial ischemia.

Development of a simple algorithm to guide the effective management of traumatic cardiac arrest.

Major trauma is the leading worldwide cause of death in young adults. The mortality from traumatic cardiac arrest remains high but survival with good neurological outcome from cardiopulmonary arrest following major trauma has been regularly reported. Rapid, effective intervention is required to address potential reversible causes of traumatic cardiac arrest if the victim is to survive. Current ILCOR guidelines do not contain a standard algorithm for management of traumatic cardiac arrest. We present a simple algorithm to manage the major trauma patient in actual or imminent cardiac arrest. We reviewed the published English language literature on traumatic cardiac arrest and major trauma management. A treatment algorithm was developed based on this and the experience of treatment of more than a thousand traumatic cardiac arrests by a physician - paramedic pre-hospital trauma service. The algorithm addresses the need treat potential reversible causes of traumatic cardiac arrest. This includes immediate resuscitative thoracotomy in cases of penetrating chest trauma, airway management, optimising oxygenation, correction of hypovolaemia and chest decompression to exclude tension pneumothorax. The requirement to rapidly address a number of potentially reversible pathologies in a short time period lends the management of traumatic cardiac arrest to a simple treatment algorithm. A standardised approach may prevent delay in diagnosis and treatment and improve current poor survival rates. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

There is an on-going discussion regarding the recurrence rate after surgery for primary spontaneous pneumothorax by video assisted thoracic surgery (VATS) or by thoracotomy access. This study aimed to describe the recurrence rate, and to identify a possible learning curve, following surgery for primary spontaneous pneumothorax by VATS. All patients who underwent surgery for primary spontaneous pneumothorax by VATS at Karolinska University Hospital 2004-2013 were reviewed. Preoperative and operative characteristics were obtained from medical records. Patients were followed-up through telephone interviews or questionnaires and by review of medical records. The primary outcome of interest was time to recurrence of pneumothorax requiring intervention. Outcomes were compared between patients operated during 2004-June 2010 and July 2010-2013. 219 patients who underwent 234 consecutive procedures were included. The mean follow-up times were 6.3 and 2.9 years in the early and late period, respectively. The postoperative recurrence rate in the early period was 16% (11%-25%), 18% (12%-27%), and 18% (12%-27%), at 1, 3 and 5 years, compared to 1.7% (0.4%-6.8%), 7.6% (3.7%-15%), and 9.8% (4.8%-19%) at 1, 3 and 5 years, in the late period (p = 0.016). We found that the recurrence rate after thoracoscopic surgery for primary spontaneous pneumothorax decreased significantly during the study period. Our results strongly suggest that thoracoscopic surgery for pneumothorax involve a substantial learning curve.

Spirometry: predicting risk and outcome.

PubMed

Brunelli, Alessandro; Rocco, Gaetano

Predicted postoperative FEV1 is certainly the most widely used parameter in preoperative risk stratification [54] and the measure recommend by BTS and ACCP functional guidelines as a first step in the screening of patients for lung resection surgery. Nevertheless, recent evidences have demonstrated that ppoFEV1 is not a reliable predictor of postoperative cardiopulmonary complications in patients with preoperative impaired pulmonary function. This may be because of the fact that the resection of a portion of lung in patients with obstructive disease determines only a minimal loss, or even an improvement, in overall respiratory function and exercise tolerance. This lung volume reduction effect takes place very early, since the first postoperative days, balancing what ever negative physiologic effects a thoracotomy and lung resection may entail. In addition to its poor predictive role in COPD patients, ppoFEV1 largely underestimate the actual loss in the very first days after operation, when most of the complications develop. The rationale to use a parameter which is poorly correlated with the pulmonary function at the moment the complications occur seems unwarranted. At the very best, ppoFEV1 appears a weak surrogate of the immediate postoperative FEV1. The FEV1 measured on the first postoperative day may be 30% less than predicted. Corrective equations have been published to correct this discrepancy with the aim to improve risk stratification.

Retrograde gastroesophageal intussusception after peroral endoscopic myotomy in a patient with achalasia cardia: A case report.

Retrograde gastroesophageal intussusception (RGEI) is a relatively rare gastrointestinal (GI) disorder in which a portion of the stomach wall invaginates into the esophagus. More recently, peroral endoscopic myotomy (POEM) has emerged as an endoscopic alternative to surgical myotomy for achalasia, and, to the best of our knowledge, our case is the first RGEI after POEM to be reported. A 22-year-old male was presented with a history of vomiting, intractable retching and hematemesis for 3 days. He had a history of achalasia and underwent POEM 3 years ago caused by symptoms of severe dysphagia to solid and liquid. Initially, the patient was diagnosed with a blood-filled esophagus, and the mid esophagus was occluded with a ball-like mass, however, the final diagnosis of RGEI was made by thoracotomy. A therapeutic strategy of conservative treatment and left transthoracic surgery were applied. The surgery and post operative course were uneventful, and he remained asymptomatic 1 year after operation. POEM is a reliable and minimally invasive endoscopic method for esophageal achalasia. Early recognition and severity of RGEI are essential to decrease the unwanted complications. Upper GI series, esophagogastroduodenoscopy and computed tomography scan are helpful for diagnostic purposes of RGEI. Conservative treatment, endoscopic intervention, and surgery are the mainstay of treatments for RGEI. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

Cardiac resynchronization via left ventricular or biventricular pacing is an option for selected patients with ventricular systolic dysfunction and widened QRS complex. Stimulation through a coronary vein is the technique of choice for left ventricular pacing, but this approach results in a failure rate of approximately 8%. We describe our initial experience with minimally invasive surgical implantation of left ventricular epicardial leads using video-assisted thoracoscopy. A total of 14 patients with congestive heart failure, NYHA functional class 3.2 (0.6) and mean ejection fraction 22.9 (6.8)% were included in this study. Left bundle branch block, QRS complex >140 ms and abnormal septal motion were observed in all cases. Epicardial leads were implanted on the left ventricular free wall under general anesthesia using video-assisted thoracoscopic surgery. Lead implantation was successful in 13 patients. Conversion to a small thoracotomy was necessary in one patient. All patients were extubated in the operating room. None of the patients died during their hospital stay. Follow-up showed reversal of ventricular asynchrony and significant improvement in ejection fraction and functional class. Minimally invasive surgery for ventricular resynchronization using video-assisted thoracoscopy in selected patients is a safe procedure that makes it possible to choose the best site for lead implantation and provides adequate short- and medium-term stimulation.

To identify breed disposition, postoperative complications, and outcome in dogs with lung lobe torsion. Retrospective study. 22 client-owned dogs. Information on signalment; history; clinical findings; results of clinicopathologic testing, diagnostic imaging, and pleural fluid analysis; surgical treatment; intra- and postoperative complications; histologic findings; and outcome were obtained from medical records. All 22 dogs had pleural effusion; dyspnea was the most common reason for examination. Fifteen dogs were large deep-chested breeds; 5 were toy breeds. Afghan Hounds were overrepresented, compared with the hospital population. One dog was euthanatized without treatment; the remaining dogs underwent exploratory thoracotomy and lung lobectomy. Eleven dogs recovered from surgery without complications, but 3 of these later died of thoracic disease. Four dogs survived to discharge but had clinically important complications within 2 months, including chylothorax, mediastinal mesothelioma, gastric dilatation, and a second lung lobe torsion. Six dogs died or were euthanatized within 2 weeks after surgery because of acute respiratory distress syndrome, pneumonia, septic shock, pneumothorax, or chylothorax. Chylothorax was diagnosed in 8 of the 22 dogs, including 4 Afghan Hounds. Results suggest that lung lobe torsion is rare in dogs and develops most frequently in large deep-chested dogs, particularly Afghan Hounds. Other predisposing causes were not identified, but an association with chylothorax was evident, especially in Afghan Hounds. Prognosis for dogs with lung lobe torsion was fair to guarded.

Safe pulmonary vessel sealing device plays a crucial role in anatomic lung resection. In 2014, we reported high rates of massive bleeding complications during transumbilical lobectomy in a canine model due to difficulty in managing the pulmonary vessel with an endostapler. In this animal survival series, we aimed to evaluate the outcome of pulmonary vessel sealing with an electrocautery device to simplify the transumbilical thoracic surgery. Under general anesthesia, a 3-cm longitudinal incision was made over the umbilicus. Under video guidance, a bronchoscope was inserted through the incision for exploration. The diaphragmatic wound was created with an electrocautery knife and used as the entrance into the thoracic cavity. Using the transumbilical technique, anatomic lobectomy was performed with electrosurgical devices and endoscopic vascular staplers in 15 canines. Transumbilical endoscopic anatomic lobectomy was successfully completed in 12 of the 15 animals. Intraoperative bleeding developed in three animals during pulmonary hilum dissection, where one animal was killed due to hemodynamic instability and the other two animals required thoracotomy to complete the operation. There were five delayed bleeding and surgical mortality cases caused by inadequate vessel sealing by electrosurgical devices. Postmortem examination confirmed correct transumbilical lobectomy in the twelve animals that survived the operations. Transumbilical anatomic lobectomy is technically feasible in a canine model; however, the electrosurgical devices were not effective in sealing the pulmonary vessel in the current canine model.

Objective To share our experience highlighting the additional use of cardiopulmonary bypass (CPB) in cases other than the conventional ischemic, congenital and valvular heart diseases. Methodology All patients undergoing non-traditional cardiac surgery utilizing the cardiopulmonary bypass during a period from 1999 to 2009 reviewed. Their preoperative presentation, operative strategy and immediate postoperative status were assessed. Results A total of six such cases were identified including three female and three male patients. Two patients presented with road traffic accident having aortic transection along with other injuries. They underwent repair utilizing partial cardiopulmonary bypass. One patient presented with large PDA aneurysm and symptoms related to its pressure effect on respiratory system. He underwent repair under hypothermic circulatory arrest. These three patients were done via left thoracotomy. Three patients underwent deep hypothermic circulatory arrest, one for removal of thrombus from right atrium after complicated liver abscess, one patient required vascular graft interposition in left internal carotid artery for aneurysm extending into cranium and the third one underwent resection of vascular tumor of posterior cranial fossa. One patient required exploration for bleeding. One patient died after prolonged hospitalization. Rest of the patient had unremarkable postoperative course and were discharged home. Conclusion Our short experience highlights the extended use of cardiopulmonary bypass in a multidisciplinary hospital, facilitating to perform complex, technically challenging non cardiac procedures which otherwise may not be possible.

To assess functional capacity in the preoperative phase of pulmonary surgery by comparing predicted and obtained values for the six-minute walk test (6MWT) in patients with and without postoperative pulmonary complication (PPC) METHOD: Twenty-one patients in the preoperative phase of open thoracotomy were evaluated using the 6MWT, followed by monitoring of the postoperative evolution of each participant who underwent the routine treatment. Participants were then divided into two groups: the group with PPC and the group without PPC. The results were also compared with the predicted values using reference equations for the 6MWT RESULTS: Over half (57.14%) of patients developed PPC. The 6MWT was associated with the odds for PPC (odds ratio=22, p=0.01); the group without PPC in the postoperative period walked 422.38 (SD=72.18) meters during the 6MWT, while the group with PPC walked an average of 340.89 (SD=100.93) meters (p=0.02). The distance traveled by the group without PPC was 80% of the predicted value, whereas the group with PPC averaged less than 70% (p=0.03), with more appropriate predicted values for the reference equations The 6MWT is an easy, safe, and feasible test for routine preoperative evaluation in pulmonary surgery and may indicate patients with a higher chance of developing PPC.

A compact device which evacuates blood from a hemothorax and facilitates rapid autotransfusion was evaluated in dogs. Experimental hemothorax was established surgically by incising the internal mammary artery through a thoracotomy with the animals under general anesthesia. Postoperatively the blood was drained by one of two methods. In the Heimlich valve group (n = 5), blood was drained by a chest tube through a one-way flutter valve into a collapsible plastic bag. In the Sorenson group (n = 5), blood was drained by a chest tube into the Sorenson Autotransfusion System. Blood from these two groups was then autotransfused. In the control group (n = 5), the drained blood was not autotransfused. Results showed no statistical difference between the two autotransfusion groups in the volume of blood collected, circulating fibrinogen levels, platelet counts, stroma-free hemoglobin levels, prothrombin time, or 51Cr-labeled RBC survival. There was a significant drop in the circulating platelet count, which returned to normal by 24 hours, in both groups of dogs which were autotransfused. We conclude that autotransfusion of blood collected by a compact device which utilizes a Heimlich valve and requires no suction is similar to using the Sorenson Autotransfusion System. It may be safe to use the Heimlich valve to collect blood for autotransfusion in clinical situations, where its qualities of simplicity, portability and a minimum requirement for storage space are desirable.

The aim of this study was to examine the baroreflex sensitivity (BRS), which involves the autonomic nervous system, in a goat with a chronically implanted undulation pump ventricular assist device (UPVAD). The UPVAD involved transforming the rotation of a brushless DC motor into an undulating motion by a disc attached via a special linking mechanism, and a jellyfish valve in the outflow cannula to prevent diastolic backflow. The pump was implanted into the thoracic cavity of a goat by a left thoracotomy, and the inflow and outflow cannulae were sutured to the apex of the left ventricle and to the descending aorta, respectively. The driving cable was wired percutaneously to an external controller. Electrocardiogram and hemodynamic waveforms were recorded at a sampling frequency of 1 kHz. BRS was determined when awake by the slope of the linear regression of R-R interval against mean arterial pressure changes, which were induced by the administration of methoxamine hydrochloride, both with continuous driving of the UPVAD as well as without assistance. BRS values during the UPVAD support and without assistance were 1.60 +/- 0.30 msec/mm Hg and 0.98 +/- 0.22 msec/mm Hg (n = 5, P < 0.05), respectively. BRS was significantly improved during left ventricular assistance. Therefore, UPVAD support might decrease sympathetic nerve activity and increase parasympathetic nerve activity to improve both microcirculation and organ function.

Cardiovascular injuries after trauma present with high mortality. The aim of the study was to present our experience in cardiac and great vessel injuries after chest trauma. During the 10-year period, 104 patients with cardiac (n=94) and great vessel (n=10) injuries presented to our hospital. The demographic data, mechanism of injury, location of injury, other associated injuries, timing of surgical intervention, surgical approach, and clinical outcome were reviewed. Eighty-eight (84.6%) males presented after chest trauma. The mean age of the patients was 32.5±8.2 years (range: 12-76). Penetrating injuries (62.5%) were the most common cause of trauma. Computed tomography was performed in most cases and echocardiography was used in some stable cases. Cardiac injuries mostly included the right ventricle (58.5%). Great vessel injuries involved the subclavian vein in 6, innominate vein in 1, vena cava in 1, and descending aorta in 2 patients. Early operations after admission to the emergency were performed in 75.9% of the patients. Thoracotomy was performed in 89.5% of the patients. Operative mortality was significantly high in penetrating injuries (p=0.01). Clinicians should suspect cardiac and great vessel trauma in every patient presenting to the emergency unit after chest trauma. Computed tomography and echocardiography are beneficial in the management of chest trauma. Operative timing depends on hemodynamic status, and a multidisciplinary team approach improves the patient's prognosis.

Cardiovascular causes of airway compression.

PubMed

Kussman, Barry D; Geva, Tal; McGowan, Francis X

2004-01-01

Compression of the paediatric airway is a relatively common and often unrecognized complication of congenital cardiac and aortic arch anomalies. Airway obstruction may be the result of an anomalous relationship between the tracheobronchial tree and vascular structures (producing a vascular ring) or the result of extrinsic compression caused by dilated pulmonary arteries, left atrial enlargement, massive cardiomegaly, or intraluminal bronchial obstruction. A high index of suspicion of mechanical airway compression should be maintained in infants and children with recurrent respiratory difficulties, stridor, wheezing, dysphagia, or apnoea unexplained by other causes. Prompt diagnosis is required to avoid death and minimize airway damage. In addition to plain chest radiography and echocardiography, diagnostic investigations may consist of barium oesophagography, magnetic resonance imaging (MRI), computed tomography, cardiac catheterization and bronchoscopy. The most important recent advance is MRI, which can produce high quality three-dimensional reconstruction of all anatomic elements allowing for precise anatomic delineation and improved surgical planning. Anaesthetic technique will depend on the type of vascular ring and the presence of any congenital heart disease or intrinsic lesions of the tracheobronchial tree. Vascular rings may be repaired through a conventional posterolateral thoracotomy, or utilizing video-assisted thoracoscopic surgery (VATS) or robotic endoscopic surgery. Persistent airway obstruction following surgical repair may be due to residual compression, secondary airway wall instability (malacia), or intrinsic lesions of the airway. Simultaneous repair of cardiac defects and vascular tracheobronchial compression carries a higher risk of morbidity and mortality.

Limited (wedge) resection of pulmonary lesions is frequently performed as a diagnostic/therapeutic procedure. Some lesions may be difficult to locate thoracoscopically with conversion to open thoracotomy or incomplete resection being potential limitations to this approach. Multiple methods have been described to aid video-assisted thoracoscopic surgical (VATS) wedge resection of pulmonary nodules, including hookwire localization, percutaneous tattoo, or intraoperative ultrasound. We report on our experience using electromagnetic navigation bronchoscopic dye marking of small subpleural lesions to aid VATS wedge resection. A retrospective cohort study of consecutive patients undergoing VATS wedge resection of peripheral lesions. Preoperative bronchoscopy with electromagnetic navigation was utilized to guide a 25 G needle to within/adjacent to the target lesion with injection of 1 mL of methylene blue or indigo carmine under fluoroscopic vision. Six patients underwent bronchoscopic marking of peripheral pulmonary lesions, navigation deemed successful in all patients, with no procedural complications. Surgery was performed within 24 hours of bronchoscopic marking. Pleural staining by dye was visible thoracoscopically in all 6 lesions either adjacent to or overlying the lesion. All lesions were fully excised with wedge resection. Pathologic examination confirmed accuracy of dye staining. Electromagnetic navigation bronchoscopic dye marking of peripheral lesions is feasible, without complications commonly associated with percutaneous marking procedures. Further experience is required but early findings suggest that this method may have utility in aiding minimally invasive resection of small subpleural lesions.

Epidural technique for postoperative pain: gold standard no more?

PubMed

Rawal, Narinder

2012-01-01

Epidural analgesia is a well-established technique that has commonly been regarded as the gold standard in postoperative pain management. However, newer, evidence-based outcome data show that the benefits of epidural analgesia are not as significant as previously believed. There are some benefits in a decrease in the incidence of cardiovascular and pulmonary complications, but these benefits are probably limited to high-risk patients undergoing major abdominal or thoracic surgery who receive thoracic epidural analgesia with local anaesthetic drugs only. There is increasing evidence that less invasive regional analgesic techniques are as effective as epidural analgesia. These include paravertebral block for thoracotomy, femoral block for total hip and knee arthroplasty, wound catheter infusions for cesarean delivery, and local infiltration analgesia techniques for lower limb joint arthroplasty. Wound infiltration techniques and their modifications are simple and safe alternatives for a variety of other surgical procedures. Although pain relief associated with epidural analgesia can be outstanding, clinicians expect more from this invasive, high-cost, labour-intensive technique. The number of indications for the use of epidural analgesia seems to be decreasing for a variety of reasons. The decision about whether to continue using epidural techniques should be guided by regular institutional audits and careful risk-benefit assessment rather than by tradition. For routine postoperative analgesia, epidural analgesia may no longer be considered the gold standard.

Traumatic cardiac arrest studies have reported improved survival rates recently, ranging from 1.7-7.5%. This population-based nationwide study aims to describe the epidemiology, interventions and outcomes, and determine predictors of survival from out-of-hospital traumatic cardiac arrest (OHTCA) in Qatar. An observational retrospective population-based study was conducted on OHTCA patients in Qatar, from January 2010 to December 2015. Traumatic cardiac arrest was redefined to include out-of-hospital traumatic cardiac arrest (OHTCA) and in-hospital traumatic cardiac arrest (IHTCA). A total of 410 OHTCA patients were included in the 6-year study period. The mean annual crude incidence rate of OHTCA was 4.0 per 100,000 population, in Qatar. OHTCA mostly occurred in males with a median age of 33. There was a preponderance of blunt injuries (94.3%) and head injuries (66.3%). Overall, the survival rate was 2.4%. Shockable rhythm, prehospital external hemorrhage control, in-hospital blood transfusion, and surgery were associated with higher odds of survival. Adrenaline (Epinephrine) lowered the odds of survival. The incidence of OHTCA was less than expected, with a low rate of survival. Thoracotomy was not associated with improved survival while Adrenaline administration lowered survival in OHTCA patients with majority blunt injuries. Interventions to enable early prehospital control of hemorrhage, blood transfusion, thoracostomy and surgery improved survival. Copyright © 2017 Elsevier B.V. All rights reserved.

Measurements of myocardial flow vs. extraction of rubidium under varying physiological conditions

The relationship between myocardial rubidium extraction (E) and flow (F) are well described by the single capillary model E = (1-exp(-PS/F)) with a permeability surface product PS = 0.87 cc/min/gm. Some effects of alkalosis and acidosis have been reported. Here the authors investigate the effects of dipyridamole, norepinephrine-atropine, exsanguination, pacing, ouabain and calcium on extraction using Rb-82 PET and Rb-86 acute studies with microspheres in dogs. Thoracotomies were performed for left atrial microsphere infusion. Anesthesia was by N/sub 2/O and methoxyflurane. The degree of exsanguination, drug levels administered and pacing rates were sufficient to produce flow modifications. Extraction was calculatedmore » by dividing FE from Rb observations by F from microsphere data. These results of extraction vs. flow do not show a significant dependence on the method used for flow modification. There was less than a 20% change in FE after an infusion of 0.04 mg/kg ouabain over 5 minutes in 3 replicate studies each on 4 dogs. An important finding not previously explained in flow vs. extraction studies is the occurrence of extraction values greater than 1.0 which is possible only if the distribution opportunities of small cations are greater than that of microspheres. This is equivalent to the well known hematocrit effect in small channels.« less

The history of thoracic surgical instruments and instrumentation.

Hagopian, E J; Mann, C; Galibert, L A; Steichen, F M

2000-02-01

Thoracic surgical practice has evolved from the innovations of its pioneers. Beginning with the stethoscope discovered by Laënnec with his system of auscultation, to the tools we use in the dissection and control of the hilum of the lung for resection, our practice of thoracic surgery has been entwined with the development of instruments and instrumentation. The development of strategies to prevent death from the open pneumothorax began with manual control of the mediastinum and progressed through differential pressure to, finally, the technique of intubation and the methods of positive-pressure and insufflation anesthesia. The instruments we place in our hands are not enough to define our art. Entry into the chest would not be possible without the use of rib retractors, rib shears, and even periosteal elevators. Finally, to the present day of minimally invasive techniques and the application of thoracoscopy for therapeutic purposes, we find the efforts of our predecessors well developed. For the progression from the fear of the open pneumothorax to the present-day state of the ease of thoracotomy for lung resection we are indebted to those who gave so much of their time and, for some, their lives to death from tuberculosis, to allow the advancement of our practice of surgery. These great people should be remembered not only for their acceptance of novel ideas but also, more importantly, for their lack of fear of testing them.

We define focal pulmonary lesion (FPL) as an intra-parenchymatous pulmonary lesion that is well circumscribed and completely surrounded by healthy lung. It is considered that the profitability of the fine needle aspiration puncture (FNAP) in FPL < or = 2 cm is better than that of the fibrobronchoscopy (FBC). To analyze the diagnostic profitability of the FNAP in the malignant FPL and study if it varies according to site, size and histology. We analyzed all the FBCs of our Unit between 01/2000 and 12/2001 in patients with solitary FLP < or = 6 cm with a definitive diagnosis of malignancy. The diagnostic profitability by size, site and histology was analyzed with Pearson's chi(2) statistics. 124 patients. Mean FBC per patient was 1.3. A total of 101 cases (82%) were diagnosed with FBC, 15 by thoracotomy and 8 by FNAP. Global diagnostic profitability of the FBC was 0.82 and the transbronchial biopsy 0.76. There are no diagnostic profitability differences by size (< or = 2 cm vs > 2 cm) (0.81 vs 0.82 p = 0.96), site (peripheral vs central) (0.79 vs 0.85 p = 0.41) and histology (epidermoid vs adenocarcinoma) (0.89 vs 0.75 p = 0.21). Profitability of the FBC in malignant FPL in our hospital is elevated without differences by size, site or histology. In our site, the initial diagnostic approach of the FLP is done with FBC.

Robotic lobectomy and segmentectomy for lung cancer: results and operating technique

PubMed Central

2015-01-01

Video-assisted thoracic surgery (VATS) is a minimally invasive approach with several advantages over open thoracotomy for the surgery of lung cancer but also some limitations like rigid instruments and suboptimal vision. Robot technology is an evolution of manual videothoracoscopy introduced to overcome these limitations maintaining the advantages related to low invasiveness. More intuitive movements, greater flexibility and high definition three-dimensional vision are advantages of the robotic approach. Different studies demonstrate that robotic lobectomy and segmentectomy are feasible and safe with long term outcome similar to that of open/VATS approaches, however no randomised comparison are available and benefits in terms of quality of life (QOL) and pain need to be demonstrated yet. Several different robotic techniques are currently employed and differ for number of robotic arms (three versus four), the use of CO2 insufflation, timing of utility incision and the port positioning. The four arms robotic approach with anterior utility incision is the technique described by the authors. Indications to perform robotic lung resections may be more extensive than those of traditional videothoracoscpic approach and includes patients with locally advanced disease after chemotherapy or those requiring anatomical segmentectomy. Learning curve of vats and robotic lung resection is similar. High capital and running costs are the most important disadvantages. Entry of competitor companies should drive down costs.

Necrotizing fasciitis (NF) of odontogenic origin affecting the head and neck region is a rare but serious clinical condition, which, if diagnosed late, can lead to a fatal outcome. The early diagnosis of necrotizing fasciitis can be difficult. Delay in diagnosis leads to increase in the area of necrosis with a resulting increase in cosmetic deformity and life-threatening complication. In this study, we present two cases of elderly patients with aggressive NF affecting the neck and anterior mediastinum, which were of odontogenic origin. In the two patients selected necrotic skin and soft tissue were removed and wide exposure was achieved with debridement of the neck at the level of the affected layer of superficial cervical fascia. Saline solution was used as irrigation to treat the patients with acute necrotizing fasciitis. Difficulties in managing this condition with NF extent to deep anterior mediastinum is related to clavicle osteotomy or thoracotomy need with high surgical risks. In our technique, by gentle suction in anterior mediastinum, necrotic tissue resection was possible without any osteotomy need. Suctioning resection technique associated with hyperbaric, metabolic rebalance, and amino acid support in association with three types antibiotic therapy are fundamental points for correct therapy strategy, leading to full recovery and healing of NF patients even if in very unfavorable conditions. Multidisciplinary approach is paramount for proper treatment of this disease.

Intrapleural bupivacaine administration is said to produce good analgesia for the pain induced by a subcostal incision. However, reports of its efficacy after thoracotomy are conflicting. The goal of this study was to compare the analgesia produced by intrapleural administration of bupivacaine after oesophagectomy using a thoraco-abdominal incision with that obtained from intrapleural saline. After informed consent and institutional approval were obtained, 20 patients were randomly assigned to two groups of 10 patients each. Subjects received intrapleurally 10 ml of either 0.25% bupivacaine with 1:200,000 adrenaline or normal saline, every 8 h, beginning on the first post-operative day and lasting for 4 days. Pain was evaluated using a visual-analogue scale 2 h after the first daily treatment at rest and during physiotherapy. Pain scores were significantly lower in the bupivacaine group than in the saline group. Additionally, PaO2 was significantly higher in the bupivacaine group than in the saline group on Day 1 (P less than 0.05). The plasma bupivacaine concentration never reached the level of toxicity. Plasma bupivacaine concentrations on Day 1 after the first intrapleural bupivacaine injection were less than 350 ng ml-1; on Day 4 after the last injection they were less than 1300 ng ml-1. In conclusion, intrapleural administration of bupivacaine produces effective analgesia after oesophagectomy performed with a thoracoabdominal incision. The technique is easy to perform and is safe.

Common historical findings in 26 cats with pyothorax were dyspnea (85%), lethargy (65%), and anorexia (62%), common clinical findings were dyspnea (89%), tachypnea (73%), fever (39%), and hypothermia (27%). Frequent laboratory abnormalities were leukocytosis (68%) with a left shift (100%), anemia (65%), hypoalbuminemia (91%), hyperglobulinemia (86%), hyperbilirubinemia (60%) as well as azotemia (52%). The thoracic effusion was purulent in all cats, the thoracic fluid evaluation (n = 19) met the criteria for an inflammatory exudate (protein 32-63 g/l, median 44; cell count 54.4-390 x 10(9)/l, median 100). Cytological analysis revealed bacteria in 21 of 24 cats. From 16 cats 13 different genera were isolated, 5 cultures were without bacterial growth. In 12.5% of the cats a single population of bacteria was identified, and in 87.5% a mixture of 2-4 different bacterial species were cultured. Obligate anaerobic bacteria were the most common isolates (70%) followed by facultative anaerob (22.5%) and aerob growing (7.5%) bacteria. Bacterial culture most often yielded Fusobacteria spp., Prevotella spp., Pasteurella spp., Porphyromonas spp. and Bacteroides spp. Three cats were euthanized at the day of presentation. A thoracic lavage was performed in 22 cats; mechanical complications with the chest tubes occured in 4 cats. Thoracotomy was performed in 2 cats. Of the 23 treated cats 17 survived (74%).

Background Foreign body aspiration refers to the inhalation of an object into the respiratory system and is a serious and potentially fatal event. A distinct group of patients has recently been recognized among Muslim nations. These patients include women who wear headscarves and place the safety pin in their mouth prior to securing the veils, leading to accidental foreign body aspiration. The aim of this study was to analyze the main presentation, diagnosis, treatment, and outcome of patients with scarf pin aspiration. Methods This prospective study involved patients with a history of scarf pin aspiration admitted to a single center during an 18-month period. Their main presentation, diagnosis, treatment, and outcome were analyzed. Results In total, 27 patients were included. The needle was extracted by flexible bronchoscopy in 12 (44.4%) patients, rigid bronchoscopy in 13 (48.1%), and thoracotomy in 2 (74%). One patient died during rigid bronchoscopy. All remaining 26 patients were satisfied with the postsurgical outcome at a mean follow-up of 1 week. Conclusions Scarf pin aspiration differs from other types of foreign body aspiration considering the specific population affected, and its management algorithm may thus differ from that of other foreign bodies. The left main bronchus is the most common site of pin impaction. Rigid bronchoscopy is the most commonly performed procedure for successful retrieval. PMID:28627978

To characterize the postmortem pulmonary disease and analyze the effectiveness of antemortem diagnosis, we examined the clinical records and autopsy material from 54 patients who died of the acquired immunodeficiency syndrome. At autopsy, all patients had pulmonary disease. One or more specific diagnoses were made in 53, including opportunistic infection, nonopportunistic infection, and Kaposi's sarcoma. Multiple postmortem pulmonary diagnoses were established in 37. Respiratory failure was the most common cause of death. Of the 97 pulmonary disorders discovered at autopsy, only 31 were diagnosed before death. The frequency with which infections were diagnosed during life varied according to the organism, and was significantly higher for Pneumocystis carinii than for cytomegalovirus or bacterial agents. Pulmonary Kaposi's sarcoma was diagnosed in only 7% of patients with autopsy documentation. The yield of diagnostic procedures also varied according to the disease present. Sputum culture was relatively effective in detecting Cryptococcus neoformans and Mycobacterium avium-intracellulare, fiber-optic bronchoscopy was extremely useful for diagnosing P Carinii, and one or more diagnoses were provided in 4 of 7 patients who underwent thoracotomy, but significant disease including cytomegalovirus infection and pulmonary Kaposi's sarcoma was frequently missed. Although the spectrum of lung disease found at autopsy is similar to that observed during life, the frequency of some pathologic processes including cytomegalovirus infection and Kaposi's sarcoma may be underrepresented in antemortem series.

diagnostic standard is a pleural biopsy with subsequent histologic examination of the tissue demonstrating invasion by the tumor. The diagnostic tissue is obtained through thoracoscopy or open thoracotomy, both being highly invasive procedures. Thoracocenthesis, or removal of effusion fluid from the pleural space, is a far less invasive procedure that can provide material for cytological examination. However, it is insufficient to definitively confirm or exclude the diagnosis of malignant mesothelioma, since tissue invasion cannot be determined. In this study, we present a computerized method to detect and classify malignant mesothelioma based on the nuclear chromatin distribution from digital images of mesothelial cells in effusion cytology specimens. Our method aims at determining whether a set of nuclei belonging to a patient, obtained from effusion fluid images using image segmentation, is benign or malignant, and has a potential to eliminate the need for tissue biopsy. This method is performed by quantifying chromatin morphology of cells using the optimal transportation (Kantorovich-Wasserstein) metric in combination with the modified Fisher discriminant analysis, a k-nearest neighborhood classification, and a simple voting strategy. Our results show that we can classify the data of 10 different human cases with 100% accuracy after blind cross validation. We conclude that nuclear structure alone contains enough information to classify the malignant mesothelioma. We also conclude that the distribution of chromatin seems to be a discriminating feature between nuclei of benign and malignant mesothelioma cells.

We developed "EVAHEART": a compact centrifugal blood pump system as an implantable left ventricular assist device for long-term circulatory support. The 55 x 64 mm pump is made from pure titanium, and weighs 370 g. The entire blood-contacting surface is covered with an anti-thrombogenic coating of diamond like carbon (DLC) or 2-methacryloyloxyethyl phosphorylcholine (MPC) to improve blood compatibility. Flows exceeding 12 L/min against 100 mmHg pressure at 2600 rpm was measured. A low-temperature mechanical seal with recirculating cooling system is used to seal the shaft. EVAHEART demonstrated an acceptably low hemolysis rate with normalized index of hemolysis of 0.005 +/- 0.002 g/100L. We evaluated the pump in long-term in-vivo experiments with seven calves. Via left thoracotomy, we conducted left ventricular apex-descending aorta bypass, placing the pump in the left thoracic cavity. Pump flow rates was maintained at 5-9 L/min, pump power consumption remained stable at 9-10 W in all cases, plasma free Hb levels were less than 15 mg/dl, and the seal system showed good seal capability throughout the experiments. The calves were sacrificed on schedule on postoperative day 200, 222, 142, 90, 151, 155, and 133. No thrombi formed on the blood contacting surface with either the DLC or MPC coating, and no major organ thromboembolisms occurred except for a few small renal infarcts. EVAHEART centrifugal blood pump demonstrated excellent performance in long-term in-vivo experiments.

To present the results of a new experimental device developed to facilitate the transapical access in endovascular treatment of structural heart diseases. It aims to reduce the risk of bleeding and complications in this type of access and demonstrate the device as a safe, fast and effective alternative. CorPoint is composed of three parts: introducer, base with coiled spring, and closing capsule. By rotating movements, the spring is introduced into the myocardium and progressively approaches the base to the surface of the heart. Guidewires and catheters are inserted through the hollow central part and, at the end of the procedure, the capsule is screwed over the base, therefore stopping any bleeding. The device was implanted in 15 pigs, weighing 60 kg each, through an anterolateral thoracotomy, while catheters were introduced and guided by fluoroscopy. All animals had minimal bleeding; introducers with diameter up to 22 Fr were used and various catheters and guidewires were easily handled. After finishing the procedure, the closing capsule was attached and no bleeding was observed at the site. This new device has proved effective, fast and secure for the transapical access. This shows great potential for use, especially by ensuring an easier and direct access to the mitral and aortic valves; the shortest distance to be traveled by catheters; access to the ascending and descending aorta; decreased bleeding complications; decreased surgical time; and the possibility of allowing the technique to evolve and become totally percutaneous.

To compare the long-term results of total and partial fundoplication on esophagus myotomy. From January 1978 to October 1998, 64 patients with achalasia or diffuse esophageal spasm underwent esophagomyotomy and antireflux operation via left thoracotomy. Twenty-one patients underwent Nissen total fundoplication (Nissen group) and 43 patients underwent Belsey Marker IV partial fundoplication (Belsey group). Clinical, radiologic, radionuclide transit, manometric, 24-hour pH monitoring and endoscopic assessments were performed before and after the operation. There was no operative death and major complications for either group. At over 6 years follow-up and compared to Belsey group, patients in Nissen group revealed a higher frequency of dysphagia (P = 0.025) and more radionuclide material retention (P = 0.044). Both operative procedures reduced the lower esophageal sphincter pressure gradient. However, in Nissen group, the esophageal diameter observed on radiology was significantly increased from 3.9 cm preoperatively to 5.5 cm postoperatively (P = 0.012), while it kept the same for Belsey group (from 5.4 to 5.3 cm, P = 0.695). Reoperation in order to relieve the recurrent dysphagia and esophageal obstruction was performed on 8 patients in Nissen group and 1 in Belsey group (P < 0.01). When treating achalasia or diffuse esophageal spasm by esophageal myotomy and an antireflux operation, a total fundoplication is not appropriate, whereas a partial fundoplication provides proper antireflux effect without significant esophageal emptying difficulty.

Epiphrenic esophageal diverticulum is a rare condition that is often associated with a concomitant esophageal motor disorder. Some patients have the chief complaints of swallowing difficulty and gastroesophageal reflux; traditionally, such diverticula have been resected via right thoracotomy. Here, we describe a case with huge multiple epiphrenic diverticula with motility disorder, which were successfully resected using a video-assisted thoracic and laparoscopic procedure. A 63-year-old man was admitted due to dysphagia, heartburn, and vomiting. An esophagogram demonstrated an S-shaped lower esophagus with multiple epiphrenic diverticula (75 × 55 mm and 30 × 30 mm) and obstruction by the lower esophageal sphincter (LES). Esophageal manometry showed normal peristaltic contractions in the esophageal body, whereas the LES pressure was high (98.6 mmHg). The pressure vector volume of LES was 23,972 mmHg 2  cm. Based on these findings, we diagnosed huge multiple epiphrenic diverticula with a hypertensive lower esophageal sphincter and judged that resection might be required. We performed lower esophagectomy with gastric conduit reconstruction using a video-assisted thoracic and hand-assisted laparoscopic procedure. The postoperative course was uneventful, and the esophagogram demonstrated good passage, with no leakage, stenosis, or diverticula. The most common causes of mid-esophageal and epiphrenic diverticula are motility disorders of the esophageal body; appropriate treatment should be considered based on the morphological and motility findings.

Trauma is the leading cause of mortality in children over one year of age in industrialized countries. In this retrospective study we reviewed all chest trauma in pediatric patients admitted to Mansoura University Emergency Hospital from January 1997 to January 2007. Our hospital received 472 patients under the age of 18. Male patients were 374 with a mean age of 9.2±4.9 years. Causes were penetrating trauma (2.1%) and blunt trauma (97.9%). The trauma was pedestrian injuries (38.3%), motor vehicle (28.1%), motorcycle crash (19.9%), falling from height (6.7%), animal trauma (2.9%), and sports injury (1.2%). Type of injury was pulmonary contusions (27.1%) and lacerations (6.9%), rib fractures (23.9%), flail chest (2.5%), hemothorax (18%), hemopneumothorax (11.8%), pneumothorax (23.7%), surgical emphysema (6.1%), tracheobronchial injury (5.3%), and diaphragm injury (2.1%). Associated lesions were head injuries (38.9%), bone fractures (33.5%), and abdominal injuries (16.7%). Management was conservative (29.9%), tube thoracostomy (58.1%), and thoracotomy (12.1%). Mortality rate was 7.2% and multiple trauma was the main cause of death (82.3%) (P<.001). We concluded that blunt trauma is the most common cause of pediatric chest trauma and often due to pedestrian injuries. Rib fractures and pulmonary contusions are the most frequent injuries. Delay in diagnosis and multiple trauma are associated with high incidence of mortality. Copyright © 2011 SEPAR. Published by Elsevier España, S.L. All rights reserved.

The feasibility and clinical application of single-hole video-assisted thoracoscope in pulmonary peripheral tumors was examined. From March, 2011 to March, 2015, we retrospectively analyzed the clinical data obtained from 32 patients with pulmonary peripheral tumor that received single-hole thoracoscopic surgery. We completed the surgery via a 1.5-cm incision on the seventh or eighth rib in midaxillary line as the observation hole, and a 4.0-5.0-cm incision in the lateral margin of pectoralis major in the fourth or fifth rib in midaxillary line as the operation hole. All the patients had completed the tumor-reductive surgery under single-hole thoracoscope successfully. None required second operation hole or needed a transfer to thoracotomy. Operation time was 40-100 min with an average of 65.78±15.87 min. Intraoperative blood loss was 20-100 ml, with an average of 47.19±26.91 ml. Post-operative chest drainage time was 3-6 days, with an average of 4.22±0.87 days. Hospitalization time after operation was 5-7 days, with an average hospitalization time of 5.97±0.82 days. No patient received a second surgery for pulmonary leak or bleeding and no patient had any complication. All the cases recovered without any problem. In conclusion, for patients with pulmonary peripheral tumor, single-hole video-assisted thoracoscope could further reduce their surgical trauma. The operation was safe and feasible and worthy of wide application.

Wound healing in cardiac surgery has become a major problem due to the impaired risk profile of many patients. The aim of this study was to prove the influence of autologous platelet gel (APG) on wound healing in a special group of high-risk patients undergoing coronary surgery. We performed a prospective, double-blind study in 44 patients with a special risk constellation relating to wound complications (obesity, diabetes, smoker, New York Heart Association (NYHA) III-IV and peripheral vascular disease). The study group was treated with APG, prepared using the Magellan platelet separator, the control group underwent conventional wound treatment. The incidence of major and minor wound complications at the thoracotomy, as well as in the area of saphenous vein harvesting, was not pronounced in either of the groups. Blood loss and pain sensations did not differ significantly either. Stay in the intensive care unit (ICU) and the in-hospital mortality were also comparable. The duration of the entire operation and the time until removing the chest-tubes were prolonged in the study group. Despite promising results in other fields of surgery, APG shows no beneficial effect in high-risk patients undergoing cardiac surgery. Probably, it depends on different types of microcirculation in atherosclerotic patients, which are quite different from those of other surgical areas. This factor may offset the existing beneficial platelet effects which could be observed, for example, in maxillo-facial surgery.

Video-assisted thoracic surgery is gradually replacing conventional open thoracotomy as the method of choice for the treatment of early-stage non-small cell lung cancers, and thoracic surgical trainees must learn and master this technique. Simulation-based training could help trainees overcome the first part of the learning curve, but no virtual-reality simulators for thoracoscopy are commercially available. This study aimed to investigate whether training on a laparoscopic simulator enables trainees to perform a thoracoscopic lobectomy. Twenty-eight surgical residents were randomized to either virtual-reality training on a nephrectomy module or traditional black-box simulator training. After a retention period they performed a thoracoscopic lobectomy on a porcine model and their performance was scored using a previously validated assessment tool. The groups did not differ in age or gender. All participants were able to complete the lobectomy. The performance of the black-box group was significantly faster during the test scenario than the virtual-reality group: 26.6 min (SD 6.7 min) versus 32.7 min (SD 7.5 min). No difference existed between the two groups when comparing bleeding and anatomical and non-anatomical errors. Simulation-based training and targeted instructions enabled the trainees to perform a simulated thoracoscopic lobectomy. Traditional black-box training was more effective than virtual-reality laparoscopy training. Thus, a dedicated simulator for thoracoscopy should be available before establishing systematic virtual-reality training programs for trainees in thoracic surgery.

Lung volume reduction surgery (LVRS) can be performed in patients with severe emphysematous disease. However, LVRS in pediatric patients has not yet been reported. Here, we report our experience with 2 cases of pediatric LVRS. The first patient was a preterm infant girl with severe bronchopulmonary dysplasia, pulmonary hypertension, and hypothyroidism. The emphysematous portion of the right lung was removed via sternotomy and right hemiclamshell incision. The patient was discharged on full-time home ventilator support for 3 months after the surgery. Since then, her respiratory function has improved continuously. She no longer needs oxygen supplementation or ventilator care. Her T-cannula was removed recently. The second patient was also a preterm infant girl with bronchopulmonary dysplasia. She was born with pulmonary hypertension and multiple congenital anomalies, including an atrial septal defect. Despite receiving the best supportive care, she could not be taken off the mechanical ventilator because of severe hypercapnia. We performed LVRS on the right lung via thoracotomy. She was successfully weaned off the mechanical ventilator 1 month after the surgery. She was discharged without severe complications at 3 months after the operation. At present, she is growing well with the help of intermittent home ventilator support. She can now tolerate an oral diet. Our experience shows that LVRS can be considered as a treatment option for pediatric patients with severe emphysematous lung. It is especially helpful for discontinuing prolonged mechanical ventilator care for patients with respiratory failure. Copyright © 2018 by the American Academy of Pediatrics.

To test the feasibility of a thoracoscopically assisted, off-pump, transcatheter ventricular reconstruction (TCVR) approach in an ovine model of left ventricular (LV) anteroapical aneurysm. Myocardial infarction (MI) was induced by coil occlusion of the middle left anterior descending artery and diagonals. Two months after MI creation, TCVR was performed via a minimal thoracotomy in eight sheep. Under endoscopic and fluoroscopic guidance, trans-interventricular septal puncture was performed from the LV epicardial scar. A guidewire was externalised via a snare placed in the right ventricle from the external jugular vein. An internal anchor was inserted over the wire and positioned on the right ventricular septum and an external anchor was deployed on the LV anterior epicardium. Serial pairs of anchors were placed and plicated together to exclude the scar completely. Immediately after TCVR, echocardiography showed LV end-systolic volume decreased from pre-procedure 58.8±16.6 ml to 25.1±7.6 ml (p<0.01) and the ejection fraction increased from 32.0±7.3% to 52.0±7.5% (p<0.01). LV twist significantly improved (3.83±2.21 vs. pre-procedure -0.41±0.94, p=0.01) and the global peak-systolic longitudinal strain increased from -5.64% to -10.77% (p<0.05). TCVR using minimally invasive access techniques on the off-pump beating heart is feasible and resulted in significant improvement in LV performance.
