Thoracoscopic esophagectomy in the prone position for esophageal cancer patients with pectus excavatum: a report of two cases.
Ontology highlight
ABSTRACT: Background
Pectus excavatum is a common thoracic deformity that can be encountered during thoracoscopic esophagectomy. Here, we report two cases of esophageal cancer complicated by pectus excavatum that were treated with thoracoscopic esophagectomy with the patients in the prone position.Case presentation
The first patient was a 64-year-old male diagnosed with esophageal cancer (cT3N0M0, Haller index 8.5) and underwent radical thoracoscopic esophagectomy in the prone position following neoadjuvant chemotherapy. The second patient was a 67-year-old male diagnosed with esophageal cancer (cT1bN0M0, Haller index 4.3), and the same procedure was performed in this patient. In cases of patients with a high Haller index, where securing the surgical field is difficult, preoperative computed tomography in the prone position can help surgeons to understand the mediastinal field of view and is safe.Conclusions
Radical thoracoscopic esophagectomy in the prone position may be a surgical option in patients with pectus excavatum.

Project description:An aberrant right subclavian artery (ARSA) with an associated nonrecurrent right inferior laryngeal nerve (NRILN) is a relatively rare anomaly that occurs at a frequency of 0.3 to 2.0% of the general population. NRILN has been mainly documented in the head and neck region; it has been rarely described in patients with esophageal cancer, especially those undergoing thoracoscopic surgery. Video-assisted thoracoscopic surgery for esophageal cancer (VATS-E) is becoming more widespread as a reliable minimally invasive surgical procedure associated with reduced perioperative complications.Herein, we report three cases of esophageal cancer with ARSA and NRILN which underwent successful VATS-E. Case 1, a 53-year-old male who had early stage esophageal cancer was performed VATS-E. Upper gastrointestinal (GI) series showed "Bayonet sign" (T1aN0M0, pStageIA in UICC). Case 2, a 75-year-old male who had advanced esophageal cancer was performed neoadjuvant chemotherapy and following VATS-E. This case had right thoracic duct and "Bayonet sign" on upper GI series (T1bN2M0, pStage IIIA in UICC). Case3, a 72-year-old male who had advanced esophageal cancer was performed neoadjuvant chemotherapy and following VATS-E (T3N2M0, pStageIIIB in UICC). All of these three cases were performed VATS-E and discharged without any complication.VATS-E in the prone position is a feasible procedure that can reduce the risk of complications with an enlarged and clear view, and knowledge of this type of anomaly is very important for surgeons who perform esophagectomy.

Project description:UnlabelledIntroductionBlunt cardiac rupture is an exceedingly rare injury.Case presentationWe report a case of blunt cardiac trauma in a 43-year-old Caucasian German mother with pectus excavatum who presented after a car accident in which she had been sitting in the front seat holding her two-year-old boy in her arms. The mother was awake and alert during the initial two hours after the accident but then proceeded to hemodynamically collapse. The child did not sustain any severe injuries. Intraoperatively, a combined one-cm laceration of the left atrium and right ventricle was found.ConclusionPatients with pectus excavatum have an increased risk for cardiac rupture after blunt chest trauma because of compression between the sternum and spine. Therefore, patients with pectus excavatum and blunt chest trauma should be admitted to a Level I Trauma Center with a high degree of suspicion.

Project description:ObjectivesThe Nuss procedure for pectus excavatum involves the risk of cardiac injury during the creation of the retrosternal tunnel and during bar introduction or removal across the tunnel. A modified novel real-time technique for the safe introduction of the Nuss bar across the crucial retrosternal tunnel blind spot during introduction and removal is described.MethodsIn 2012, we devised a technique for real-time endovision-guided introduction of the Nuss bar called pectus tunneloscopy. Between February 2012 and December 2012, 6 patients with pectus excavatum had their bar introduced across the tunnel using this technique.ResultsThis technique provided safe introduction and removal of the bar during the multiple times the bar is remodelled before final fixation.ConclusionsPectus tunneloscopy is a real-time endovision surgical technique, providing safe introduction of the bar across the crucial retrosternal tunnel blind spot.

Project description:BackgroundMajor intraoperative hemorrhage reportedly predicts unfavorable survival outcomes following surgical resection for esophageal carcinoma (EC). However, the factors predicting the amount of blood lost during thoracoscopic esophagectomy have yet to be sufficiently studied. We sought to identify risk factors for excessive blood loss during video-assisted thoracoscopic surgery (VATS) for EC.MethodsUsing simple and multiple linear regression models, we performed retrospective analyses of the associations between clinicopathological/surgical factors and estimated hemorrhagic volume in 168 consecutive patients who underwent VATS-type esophagectomy for EC.ResultsThe median blood loss amount was 225 mL (interquartile range, 126-380 mL). Abdominal laparotomy (p<0.001), thoracic duct resection (p=0.014), and division of the azygos arch (p<0.001) were significantly related to high volumes of blood loss. Body mass index and operative duration, as continuous variables, were also correlated positively with blood loss volume in simple linear regression. The multiple linear regression analysis identified prolonged operative duration (p<0.001), open laparotomy approach (p=0.003), azygos arch division (p=0.005), and high body mass index (p=0.014) as independent predictors of higher hemorrhage amounts during VATS esophagectomy.ConclusionAs well as body mass index, operation-related factors such as operative duration, open laparotomy, and division of the azygos arch were independently predictive of estimated blood loss during VATS esophagectomy for EC. Laparoscopic abdominal procedures and azygos arch preservation might be minimally invasive options that would potentially reduce intraoperative hemorrhage, although oncological radicality remains an important consideration.

Project description:BackgroundTotal pharyngolaryngoesophagectomy (TPLE) is associated with major complications and is extremely invasive. In 2011, our institution introduced thoracoscopic esophagectomy in the left hemi-prone position and laparoscopic reconstruction with a gastric tube in patients undergoing TPLE. Herein, we describe the use of this operative method in 26 patients, focusing on the technical aspects of the surgery.Materials and methodsFrom January 2011 to December 2018, 26 patients underwent minimally invasive TPLE with gastric tube reconstruction in our institute. The thoracoscopic procedure was performed with the patient in the semi-prone position. The patient was then moved to the supine position, and the laparoscopic procedure and pharyngolaryngectomy were started simultaneously. After pharyngolaryngectomy, microvascular anastomoses or free jejunal flap interposition were performed at the site of the gastric tube reconstruction. The data from these 26 patients were retrospectively analyzed.ResultsThe median age was 66 years, and 3.8% of the patients were female. The Union for International Cancer Control stages of esophageal cancer were 0 (n = 2), I (n = 4), II (n = 7), III (n = 8), and IV (n = 5). Eight patients had concomitant esophageal cancer and head and neck cancer. Reconstruction with only a narrow gastric tube was used in 16 patients, while free jejunal flap interposition was used in 10 patients. The surgical procedures resulted in minimal complications. Postoperative complications of Clavien-Dindo grade ≥1 included anastomotic leakage in two patients and pneumonia in one.ConclusionThoracoscopic esophagectomy in the left hemi-prone position and laparoscopic reconstruction with a gastric tube in patients undergoing TPLE was safe and effective. The complications were improved via the development of various procedures. Further improvement is necessary before this thoracoscopic approach is established as a standard procedure for TPLE.

Project description:BackgroundIt is unclear if amianthoid transformation (AT) of costal cartilage extracellular matrix (ECM) has an impact on the development of pectus excavatum (PE) and pectus carinatum (PC).MethodsAT foci were examined in intrasurgical biopsy specimens of costal cartilages of children (8-17 years old) with PE (n = 12) and PC (n = 12) and in age-matching autopsy control samples (n = 10) using histological and immunohistochemical staining, atomic force and nonlinear optical microscopy, transmission and scanning electron microscopy, morphometry and statistics.ResultsAT areas were identified in the costal cartilage ECM in children with normal chest, PE and PC. Each type of the AT areas ("canonical", "intertwined", "fine-fibred" and "intralacunary") had a unique morphological pattern of thickness and alignment of amianthoid fibers (AFs). AFs were formed via lateral aggregation of collagen type II fibrils in the intact ECM. Foci of the AT were observed significantly more frequently in the PE and PC groups. The AT areas had unique quantitative features in each study group.ConclusionAT is a structurally diverse form of ECM alteration present in healthy and pathological costal cartilage. PE and PC are associated with specific AT disorders.

Project description:We performed the technique of uniportal thoracoscopic McKeown esophagectomy. The incision was located in the fourth intercostal space on the right axillary midline. The right recurrent laryngeal nerve lymph nodes were dissected. Four hemlocks were applied to clamp the proximal and distal ends of the aortic arch. The esophagus was suspended with purse-string at the level of the azygos vein arch to assist the dissection of the left recurrent laryngeal nerve lymph nodes. A silk thread was drawn out from the incision in order to remove the subcarinal lymph nodes. A thoracic drainage tube was placed at the back of the incision at the end.

Project description:INTRODUCTION:Although the Nuss procedure provides excellent cosmetic results for the correction of pectus excavatum, the provision of analgesia following such procedures can be challenging. METHODS:The current study retrospectively reviews our experience over a 2.5 year period with thoracic epidural analgesia (TE), paravertebral blockade (PVB), and intravenous opioids delivered via patient-controlled analgesia (PCA) to provide postoperative analgesia. RESULTS:The study cohort included 30 patients (mean age = 15.6 ± 1.5 years), 15 of whom were treated with PCA, 8 with TE, and 7 with PVB. There were no significant differences in pain scores between the 3 groups at any time point during the first 3 postoperative days. Compared to PCA, the PVB group had lower opioid consumption over the first 24 hours of hospitalization by 1.7 mg/kg morphine equivalents (95% CI of difference: 0.1, 3.3; p=0.035); but had higher opioid consumption by 2.0 mg/kg morphine equivalents than the TE group (95% CI of difference: 0.3, 3.7; p=0.024). There were no differences in opioid consumption between PVB and PCA or between PVB and TE at 48 or 72 hours. The number of intraoperative hypotension episodes was significantly lower in the PCA group when compared to the PVB group (p=0.001), with no difference between the PVB and TE groups. CONCLUSIONS:The use of regional anesthesia should be considered a viable option for the relief of postoperative pain in pediatric patients following the Nuss procedure albeit with a higher incidence of intraoperative hemodynamic effects. A randomized, prospective, study powered to compare all 3 techniques against one another would be necessary to confirm the significance of these findings.

Project description:Pectus excavatum (PE) is one of the most frequently reported chest deformities. However, limited studies are available with regard to its CT scan findings in cats. In the present research computed tomographic images of the thoraxes of 14 cats diagnosed with PE has been reviewed. This is one of the first studies exploring the use of CT to characterise PE in animals. The aim of this study was to present characteristic CT features of PE in cats. The introduction of new criteria for better assessing thoracic wall deformity-a correction index (CI) and an asymmetry index (AI)-was also proposed. The study revealed a high variety of morphological features of PE in cats. It was demonstrated that among the 14 cats: cranial PE (an atypical location) occurred in seven cats while seven cats had typical (caudal) PE, long PE occurred in five cats, while short PE had nine cats. Of the 14 cats included in the study eight showed symmetric PE, and asymmetric PE was found insix. Thoracic asymmetry was found in six cats. Six cats had sternal torsion. Based on the Vertebral Index moderate or severe PE was revealed in 11 animals. In the group of cats studied the CI ranged from 12.20 to 32.11. The magnitude of AI did not exceed 10% in any of the cats studied. The study confirmed statistically significant differences in the CI values between groups of cats with different degrees of PE severity (p = 0.02). CT examination showed many PE features that have not been discussed so far. The main benefit of CT examination is its ability to reveal asymmetric PE, thoracic asymmetry and sternal torsion. CI and AI provided a clinically useful tool to quantify thoracic wall deformity in order to obtain comparable results between cats with PE.

Project description:BackgroundPectus excavatum is the most common chest wall deformity and is associated to various connective tissue, cardiopulmonary, and skeletal abnormalities. Several conditions and syndromes have been associated to pectus excavatum, although the overall health implications of the pectus excavatum phenotype are unclear. Therefore, in this study we aimed to examine the health implications of the pectus excavatum phenotype by assessing all comorbidities and previous medical conditions in a cohort of patients undergoing pectus excavatum surgery.MethodsThis single-centre retrospective prevalence study included 1,046 patients undergoing minimal invasive repair of pectus excavatum from 2001 to 2012. Hospital medical charts were assessed and comorbidities and previous medical conditions were registered systematically and categorized according to the affected organ system.ResultsIn our study population of 1,046 patients, we registered 623 conditions. The median age was 17 years and the majority of patients (56%) had no previous or present conditions. Notable prevalence of asthma (8.8%), allergies (12.3%), previous hernia surgery (5.2%), and psychiatric conditions (4.9%) were found.ConclusionsThe majority of patients undergoing pectus excavatum surgery have no comorbidities or previous medical conditions. It seems that this patient category is comparable to the background population in this regard and our findings do not support screening this patient category for associated conditions.
