    SummaryPigtail catheter for drainage of pleural effusion has gained popularity. Complication related to the insertion of these small-bore catheter is low. In this report, we highlight two cases with devastating necrotizing fasciitis of chest wall following pigtail catheter insertion

    BackgroundThe present study aimed to evaluate the performance of transtracheal thoracic exploration and pericardial window creation in a canine survival model.MethodsTransthoracic exploration was performed in 14 dogs. Under general anesthesia, after an incision in the right lateral wall of the middle–lower portion of the trachea was made, a 9-mm metal tube was advanced into the thoracic cavity. For thoracic cavity exploration and pericardial window creation, a flexible bronchoscope was introduced through the metal tube into the thoracic cavity. After thoracoscopy, a Dumon stent (Novatech, Grasse, France) was used to cover the tracheal incision site and facilitate healing. Animals were evaluated by endoscopy 1 and 2 weeks later. Animals were humanely killed, and necropsy was performed 2 weeks after the transtracheal natural orifice transluminal endoscopic surgery.ResultsFourteen dogs underwent transtracheal thoracic exploration lasting for an average of 110 minutes (range, 80–150), with 3 perioperative deaths. At 2 weeks after pericardial window creation, endoscopy revealed normal healing of the tracheal incision sites in all 11 surviving animals. Necropsy on the 11 animals at 2 weeks showed 9 adhesions around the pericardial window and 5 adhesions around the tracheal incision region. No mediastinitis or abscesses could be identified.ConclusionsTranstracheal thoracic exploration is technically feasible. Increasing surgical experience together with improvement in endoscopic techniques will further facilitate the development of natural orifice transluminal endoscopic surgery for thoracic diseases

    <p>Abstract</p> <p>Background</p> <p>Although the outcomes of caustic ingestion differ between children and adults, it is unclear whether such outcomes differ among adults as a function of their age. This retrospective study was performed to ascertain whether the clinical outcomes of caustic ingestion differ significantly between elderly and non-elderly adults.</p> <p>Methods</p> <p>Medical records of patients hospitalized for caustic ingestion between June 1999 and July 2009 were reviewed retrospectively. Three hundred eighty nine patients between the ages of 17 and 107 years were divided into two groups: non-elderly (< 65 years) and elderly (≥ 65 years). Mucosal damage was graded using esophagogastroduodenoscopy (EGD). Parameters examined in this study included gender, intent of ingestion, substance ingested, systemic and gastrointestinal complications, psychological and systemic comorbidities, severity of mucosal injury, and time to expiration.</p> <p>Results</p> <p>The incidence of psychological comorbidities was higher for the non-elderly group. By contrast, the incidence of systemic comorbidities, the grade of severity of mucosal damage, and the incidence of systemic complications were higher for the elderly group. The percentages of ICU admissions and deaths in the ICU were higher and the cumulative survival rate was lower for the elderly group. Elderly subjects, those with systemic complications had the greatest mortality risk due to caustic ingestion.</p> <p>Conclusions</p> <p>Caustic ingestion by subjects ≥65 years of age is associated with poorer clinical outcomes as compared to subjects < 65 years of age; elderly subjects with systemic complications have the poorest clinical outcomes. The severity of gastrointestinal tract injury appears to have no impact on the survival of elderly subjects.</p

    Background: The last few years have seen the emergence of minimally invasive mediastinal parathyroidectomy. Here, we report our single-center experience with this procedure. Materials and Methods: Between December 2002 and September 2017, we performed minimally invasive mediastinal parathyroidectomy in 12 patients with primary (n = 4) or secondary (n = 8) hyperparathyroidism (median age: 54.5 years; interquartile range: 50.5 − 62.75 years). The following variables were retrospectively collected from clinical records: demographic characteristics, results of imaging studies, surgical approach, complications, and final pathological diagnosis. Results: Technetium-99 m sestamibi examinations were performed for preoperative localization of the ectopic parathyroid glands in 11 patients (91.67%). All cases successfully underwent minimally invasive mediastinal parathyroidectomy, without the necessity to convert to open surgery. The most commonly used minimally invasive approach was video-assisted thoracoscopic surgery (n = 10; 83.33%) followed by mediastinoscopy (n = 2; 16.67%). The anatomical locations of the ectopic glands were as follows: intrathymic in six patients (50%), within the aortopulmonary window in 1 patient (8%), and in other intrathoracic sites in five patients (42%). Parathyroid adenomas and parathyroid hyperplasias were diagnosed in 5 (42%) and seven patients (58%), respectively. There were no perioperative deaths, and the median length of hospital stay was 5.5 days. Conclusion: Minimally invasive removal of mediastinal ectopic parathyroid glands is safe and feasible if their anatomical position is accurately determined. Surgical approaches depend on gland location and the surgeon's preference

    Feasibility of transumbilical anatomic “Lung” segmentectomy in a canine model

    Summary: Background: Transumbilical approach has been shown to be feasible to perform lung wedge resection and anatomic lobectomy. This study uses a canine model to assess the feasibility of transumbilical segmentectomy. Methods: Transumbilical segmentectomy was performed in 10 beagle dogs using a 3-cm umbilical incision combined with a 2.5-cm diaphragmatic incision. We evaluated the surgical outcomes, operative complications, physiologic changes, hemodynamic changes, and inflammatory changes of the procedures. Results: Transumbilical segmentectomy was successfully completed in eight of ten animals. There was one mortality complication related to lung injury causing hemodynamic collapse. Another animal required conventional thoracotomy to complete the surgery due to limited working space. There were no notable events in the postoperative period for all eight dogs that completed the segmentectomy via the transumbilical approach. Conclusion: This animal study demonstrates that the pulmonary segmentectomy can be performed with current standard endoscopic instruments via a single transumbilical incision.We believe that advancing surgical innovation and good collaboration between multi-disciplinary research teams will further establish clearer roles for transumbilical segmentectomy in thoracic surgery.
