ABSTRACT

BACKGROUND/AIMS: We applied a back light system (BLS) with a magnifying glass to improve the ability to assess the adequacy of specimen sampling using endosonography. We conducted this study to evaluate the efficacy of the BLS in sampling of specimens by endoscopic ultrasound-guided fine needle aspiration of solid pancreatic masses. METHODS: This was a prospective, randomized, crossover, single-center clinical trial. An endosonographer evaluated adequacy on gross visual inspection and identified whitish specimen sampling sites with and without the BLS according to a randomization sequence in the first and second passes with a 25-G needle. On cytological evaluation, the presence of well-defined pancreatic ductal epithelium was evaluated by a cytopathologist who was blinded to any clinical information. RESULTS: A total of 80 consecutive patients were eligible during the study period. Adequacy was observed for 52 specimens (65%) with the BLS and 54 (68%) without the BLS (p=0.88). In assessment of specimen adequacy on gross examination, only fair agreement was observed both with and without BLS (kappa score 0.40 and 0.29, respectively). CONCLUSIONS: The BLS did not influence the ability to identify specimen sampling sites or reliable assessment of specimen site adequacy using gross visual inspection.

ABSTRACT

A 76-year-old man with a history of total esophagectomy and retrosternal gastric tube reconstruction for esophageal cancer was transferred to our hospital because of consciousness disorder. It became an emergency operation on diagnosis of Stanford type A acute aortic dissection on enhanced CT. Because CT showed the retrosternal gastric tube ran along the right side of the body of the sternum through the back side of the manubrium, we opted for skin and the suprasternal incision on the left side from center. We could perform total aortic arch replacement without the damage of the gastric tube except that the right side of the operative view was slightly poor. We did not recognize digestive organ symptoms such as postoperative passage disorders nor mediastinitis. The patient was discharged from our hospital on postoperative day 24.
