Introduction: Lymphatic dissemination of a (non-cervical) esophageal tumor to the neck is generally considered as distant metastasis. The aim of this study was to determine the additional value of external ultrasonography (US) to detect lymphatic metastasis to the neck after normal CT scan (CT) with or without normal PET scan (PET)., Methods: Between January 2003 and December 2005, 306 patients were analyzed for esophageal cancer in our department. A total of 233 patients underwent both CT and external US of the neck. PET was performed in 109 of these patients as part of a prospective cohort study. Fine needle aspiration (FNA) was only performed if external US reported suspected lymph nodes. FNA was defined as gold standard., Results: In 176 patients (76%), CT did not identify any suspected nodes, but external US disagreed in 36 of them. In 9 of these patients, FNA confirmed metastasis, resulting in an additional value of external US after normal CT scanning of 5% (9/176). In 74 patients (68%), CT and PET did not identify any suspected nodes, but external US disagreed in 11 of them. In 3 of these patients, FNA confirmed metastasis, resulting in an additional value of external US after normal CT and PET of 4% (3/74)., Conclusion: Considering its minimal invasiveness and wide availability in combination with the importance of the potential therapeutic consequences, we conclude that external US of the neck should be part of the routine diagnostic work-up in patients with esophageal cancer, even after normal CT and PET scanning., (Copyright (c) 2009 S.

Background/aims: Current guidelines for staging oesophageal cancer recommend a series of preoperative investigations. There is no consensus on the recommended order for these investigations or whether all investigations are necessary in all patients. Our aim was to determine an efficient strategy for pre-treatment staging of patients with oesophageal cancer., Methods: We retrospectively compared 15 staging strategies, based on all possible orders of all possible subsets of three staging modalities (computed tomography, endoscopic ultrasonography and external ultrasonography of the neck). We assumed that if distant metastases or local irresectability were found and confirmed, no further investigations would be performed. Main outcome was the minimal number of investigations needed to detect all patients with incurable disease., Results: Using all three investigations in all 412 patients would lead to performance of 1,236 investigations. Both strategies starting with computed tomography or endoscopic ultrasonography and ending with external ultrasonography were most efficient, using a total of 1,112 investigations., Conclusion: The use of a conditional staging strategy with a specific order of imaging can reduce the number of tests necessary to identify incurable patients with oesophageal cancer by 10%. In our opinion, this is not enough to recommend implementation of a logistically more complex diagnostic system., (Copyright 2009 S. Karger AG, Basel.)

Background: Chyle leakage from the chest after extended esophagectomy originating from the abdomen is a rare complication with various clinical presentations and treatments., Methods: Two cases of chylothorax originating from the abdomen are discussed and the literature concerning diagnosis, management and outcome is reviewed., Results and Conclusion: Initially conservative measures should be installed; however, prolonged conservative treatment should be avoided. Reoperation gives an opportunity to identify the leak. If the leakage originates from the abdomen, compartimentalization is the essential step to solve the problem.
