Percutaneous Treatment of High-Output Chylothorax with Embolization or Needle Disruption Technique

Thoracoscopic ligation of the thoracic duct in a child with spontaneous chylothorax

We report a case of a 2-year old girl with a spontaneous chylothorax who presented with respiratory distress. The management of this condition, which included thoracic duct ligation using a thoracoscopic technique, is discussed, and we review the literature on chylothorax.

Surgical factors influence the outcome after Ivor-Lewis esophagectomy with intrathoracic anastomosis for adenocarcinoma of the esophagogastric junction: a consecutive series of 240 patients at an experienced center

BACKGROUND

Despite a considerable number of randomized studies, the surgical approach to locally advanced adenocarcinoma of the esophagogastric junction (AEG) I and II is still discussed controversially. Thus, we evaluated the surgical risk and outcome after an abdominothoracic esophagectomy (Ivor-Lewis) with intrathoracic anastomosis as standard procedure.

METHODS

Between 1998 and 2006, a total of 240 consecutive patients underwent standardized right thoracoabdominal esophagectomy with two-field lymphadenectomy and intrathoracic anastomosis (Ivor-Lewis operation) for AEG I (n = 206) or AEG II (n = 34). A total of 157 patients (65.4%) had neoadjuvant chemotherapy.

RESULTS

Postoperative morbidity occurred in 17.9% (43 of 240). Overall mortality was 3.8% (9 of 240). The majority of patients (4 of 9) died because of severe pulmonary complications (44.4%) irrespective of surgical complications. Neoadjuvant chemotherapy did not increase morbidity or mortality. The median overall survival was 51 months. Multivariate analysis including age >75 years, clinical response to chemotherapy, complications, R-category and N-category revealed R-category (P = .005; relative risk [RR] 0.32, 95% confidence interval [95% CI] 0.14-0.70) and complications (P < .001, RR 0.16, 95% CI 0.08-0.35) as independent prognostic factors for all patients. Complications was the only independent prognostic factor (P < .001, RR 0.09, 95% CI 0.08-0.35) for the R0 resected patients.

CONCLUSIONS

At an experienced center, Ivor-Lewis resection is a safe surgical procedure. Outcome of patients was significantly influenced by surgical factors such as complete resection and complications. Neoadjuvant chemotherapy did not lead to higher morbidity and mortality. The high mortality from non-surgery-related complications emphasizes the importance of careful preoperative evaluation of comorbidities and patient selection.

Thoracic duct embolization: a new treatment for massive leak after neck dissection

Chylothorax results from injury to the thoracic duct or one of its branches. It is an uncommon but possibly serious complication of thoracic or head and neck surgery. We report a case of thoracic duct transection complicating a total laryngectomy with bilateral selective neck dissection for subglottic squamous cell carcinoma. High-output Jackson Pratt drainage was noted, resulting in patient hypovolemia that was unresponsive to volume resuscitation. Treatment consisted of percutaneous embolization of the thoracic duct proximal to the transection that subsequently normalized chylous output.

Percutaneous radiological management of high-output chylothorax with CT-guided needle disruption

We present the study of a 58-year-old man who underwent percutaneous management of a high-output chylothorax following cardiac bypass graft surgery. The patient presented to a peripheral hospital 3 weeks postoperatively following cardiac bypass graft surgery with shortness of breath. A chest radiograph taken on arrival to the emergency department showed a large left-sided pleural effusion. Subsequent intercostal chest tube insertion drained a large amount of chylous fluid. The patient was treated conservatively with no improvement until undergoing a CT-guided needle disruption of lymphatics with good effect. This case is presented to show the minimally invasive treatment methods that are available in the management of high-output chylothorax.

Postoperative Imaging of Esophageal Cancer: What Chest Radiologists Need to Know

A variety of surgical procedures are used in the treatment of esophageal cancer. These procedures include transthoracic esophagectomy (Ivor Lewis procedure, McKeown procedure, left thoracoabdominal approach), transhiatal esophagectomy, and various forms of bypass surgery. Although meticulous surgical techniques and improved postoperative care have markedly reduced the complications associated with these techniques, esophageal resection is still associated with various intraoperative complications (hemorrhage, injury to the tracheobronchial tree, recurrent laryngeal nerve injury) and postoperative complications (anastomotic leak; mediastinitis; respiratory problems, including pleural effusion, pneumonia, and acute respiratory distress syndrome; cardiac and functional complications). Postoperative tumor recurrence is not uncommon in patients undergoing curative resection for esophageal cancer and can be categorized as either locoregional (locoregional lymph node metastases, anastomotic recurrence) or distant (hematogenous metastases, pleural or peritoneal seeding). Hematogenous metastases most commonly involve the liver, lungs, and bones, followed by the adrenal glands, brain, and kidneys. Hematogenous metastases may also involve multiple organs simultaneously. The sophisticated surgical procedures used in esophagectomy can result in anatomic changes and confound image interpretation. The radiologist must understand how these procedures can affect imaging data and be familiar with the appearances of postoperative anatomic changes, complications, and tumor recurrence to ensure accurate evaluation of affected patients.

Administration of Octreotide for Management of Postoperative High-Flow Chylothorax

Chylothorax is a rare complication of adult cardiothoracic surgery that can affect the postoperative course as it can lead to respiratory insufficiency, protein loss, fluid imbalance, and immunodeficiency. We report the case of a 51-year-old man who developed a persistent high-flow chylothorax after replacement of the descending thoracic aorta for an aneurysm. After a week of complete oral intake cessation and total parenteral nutrition, we started administration of octreotide, a somatostatin analog. It led to rapid cessation of chyle production, and the patient was discharged without further complications and chylothorax relapses.
