Risk of chyle leak after robotic versus video-assisted thoracoscopic esophagectomy.

BACKGROUND: We investigate the incidence and risk factors for post-operative outcomes including chyle leak following minimally invasive esophagectomy (MIE). METHODS: Patients undergoing MIE from May 2016 until August 2020 were prospectively followed. Outcomes of robotic and video-assisted thoracoscopic surgery (VATS) esophagectomy were analyzed. RESULTS: 347 esophagectomies were performed: 70 cases were done robotically by 2 surgeons and 277 by VATS by 14 surgeons. Patients had similar demographics, surgical technique, length of stay (LOS), and re-operation rates. Overall complication rates between robotic and VATS MIE were statistically similar (61% vs. 50%; p = 0.082). The majority of complications for either VATS (41.5%) or robotic-assisted minimally invasive esophagectomy (RAMIE) (51.4%) were grade II. Nineteen patients developed a chyle leak. Patients with a chyle leak were similar in age, gender, and hospital LOS (all p > 0.05), but were more likely to undergo a three-hole or robotic esophagectomy (both p < 0.05) as well as have higher rehabilitation requirements on discharge (26% vs. 10%; p = 0.05). Among the two surgeons who each performed > 20 robotic esophagectomies (n = 70), nine chyle leaks occurred. Rates varied by surgeon (7 vs. 2; p = 0.003). Lower leak rates occurred in the surgeon with more robotic esophagectomy experience (n = 47 vs. 23). Patients were similar in age, and gender (p > 0.05), but those with a chyle leak were more likely to undergo three-hole esophagectomies, prophylactic thoracic duction ligations, undergo the abdominal portion via laparotomy, and not have a prophylactic omental flap (all p < 0.05). CONCLUSION: Robotic and VATS esophagectomy have similar rates of re-operation, length of stay, discharge needs and complications. Differences in outcomes between VATS and Robotic esophagectomy appears to be related to surgeon experience with the robot but may also be associated with techniques such as anastomotic height, omental flap utilization and performance of laparoscopy.

Treatment of a chronic esophageal perforation after vertebral surgery with external vacuum therapy - a case report.

Esophageal perforations of any cause may escape early diagnosis and progress to lethal mediastinitis despite aggressive management. The treatment and outcome depends on the extent and chronicity of the injury. A CASE REPORT: We present a case of a late-diagnosed cervical esophageal rupture treated successfully with external vacuum therapy. A blunt trauma patient with cervical vertebral column fractures underwent fixation with a titanium bracket. A procedure-related esophageal perforation created an open fistulous communication to the skin. This was diagnosed with one month's delay. In diagnostic endoscopy the prosthesis was visible through a large esophageal defect. Evidence of mediastinitis was absent. The external wound was explored and a standard vacuum device was inserted. Nine weeks of continuous vacuum therapy achieved complete fistula closure and prevented infection. Mediastinitis was avoided and complete oral feeding was resumed. CONCLUSIONS: Different clinical presentations indicate surgical, endoscopic or conservative treatment. In this report, we provide the ground for discussion for the alternative application of the vacuum technology in a case where otherwise surgery would be the definite treatment.

Intrapericardial Hernia after Transdiaphragmatic Approach of Intrathoracic IVC.

Trauma and abdominal surgery that involves the diaphragm and pericardium rarely ends up in post-operative visceral herniation into the pericardial cavity. Urgent intervention is crucial to restore the cardiac output and prevent bowel strangulation. A case of a patient with intrapericardial hernia following nephrectomy for renal cell carcinoma and en block resection of an IVC neoplasmatic thrombus via transdiaphragmatic approach is presented.

Combining Minimally Invasive Techniques in Managing a Frail Patient with Postpneumonectomy Bronchopleural Fistula.

A postpneumonectomy bronchopleural fistula is a life-threatening complication requiring aggressive treatment and early repair. Reoperations are common due to initial treatment failure. Advanced bronchoscopic techniques are rapidly evolving, but permanent results are questionable. We report the minimally invasive management of a frail 79-year-old patient with postpneumonectomy fistula in respiratory failure due to repeated infections. Previous bronchoscopic closure attempts with fibrin failed. The multistep interdisciplinary management included airway surveillance by virtual bronchoscopy, percutaneous fibrin glue instillation under computed tomography, and awake thoracoscopic surgery to achieve temporary closure. This provided an acceptable long period of symptomatic and physical improvement. The bronchial stump failed again four months later, and the patient succumbed to pneumonia. Pneumonectomy has to be avoided unless strongly indicated. Complications are best managed with surgery for definite treatment. We emphasize our approach only when a patient declines surgery or is medically unfit as a temporary time-buying strategy in view of definite surgery in a high-volume center.

Pericardial Synovial Sarcoma: Case Report, Literature Review and Pooled Analysis.

BACKGROUND: Pericardial synovial sarcomas (PSS) are very rare tumors, with dismal prognosis and limited data. We describe the clinical features and identify prognostic factors of primary PSS. CASE REPORT: We describe the case of a 56-year-old male patient with PSS managed by the multidisciplinary team of thoracic oncology. The therapeutic plan comprised surgery, chemotherapy, stereotactic radiosurgery and targeted therapy, with excellent results. MATERIALS AND METHODS: Data from 37 cases reported in English during the past 20 years were gathered and analyzed. PSS was found to occur at a mean age of 36±17.082 (range=13-67) years. Survival analysis was performed on 20 cases with follow-up of at least 6 months. CONCLUSION: Only complete resection of the tumor seems to be an independent prognostic factor. To our knowledge, this is the first report on the safety and effectivity of pazopanib in PSS and may provide guidance for similar cases in the future.

Multiple Giant Coronary Artery Aneurysms Surgically Treated with Bypass Grafting: A Challenging Rarity.

Coronary artery aneurysms are encountered in daily cardiology practise but multiple giant-sized coronary artery aneurysms are extremely rare. We present an illustrative case of multiple giant aneurysms located throughout the coronary system (left main stem and all left, right, and circumflex branches) in a 57-year-old male with acute coronary syndrome. The case was managed successfully with on-pump quadruple coronary artery bypass grafting. To our knowledge, few cases of multiple giant aneurysms in all coronary vessels have been reported.

Atrial mass: a myxoma?

A middle-aged woman with a history of resected colorectal cancer and receiving chemotherapy presented with a right atrial mass and the provisional diagnosis of myxoma supported by echocardiography, computed tomography, and magnetic resonance imaging. Successful surgical removal revealed organized thrombus instead. Atrial thrombus may be mistaken for myxoma and long-term intracardiac indwelling catheters can be thrombogenic.

Novel technique in managing bronchobiliary fistula in adults: Endobronchial embolization using silicone spigots in 2 cases.

Bronchobiliary fistula (BBF) can complicate most hepatic pathologies. This is a challenging group of patients, especially when surgery is precluded. The bronchoscopic application of silicon spigots is a recognized technique for the treatment of massive hemoptysis and the management of patients with bronchopleural fistula following lung resection. Their role in the treatment of BBF has never been described. In this paper we report the successful embolization using silicon spigots in two patients with BBF secondary to malignant disease, when all surgical options were exhausted.

The expanded role of extracellular matrix patch in malignant and non-malignant chest wall reconstruction in thoracic surgery.

OBJECTIVES: The extracellular matrix (XCM Biologic Tissue Matrix) is a non-cross-linked 3D patch derived from porcine dermis. Once implanted, it is infiltrated by recipient's cells and becomes incorporated in the repair. Here, we report the first series of using this device for chest wall reconstruction. METHODS: The XCM Biologic Tissue Matrix was utilized to provide the restoration of chest wall defects. It was used either alone or in conjunction with the Synthes titanium system to provide additional support. The decision was made intraoperatively. RESULTS: Since April 2010, 21 (12 females) patients received the device. Average age at operation was 47 ± 17 years. Eleven (52%) patients had the patch inserted alone, while the remaining 10 received it in combination with another implantable medical device. The biological tissue matrix was used to reconstruct chest wall defects in cancer involving chest wall (n = 9), chest wall deformity (n = 6), chest wall hernia (n = 5) and chest wall repair following empyema drainage (n = 1). Complications were witnessed in 3 patients receiving the combined XCM and Synthes bar mechanisms; infection (n = 2) and bar displacement and infection (n = 1). CONCLUSIONS: The XCM patch can be safely used to provide the strength required for chest wall reconstruction and to replace previously infected reconstructions.
