Submucosal Fibrosis

Introduction: Gastric cancer is one of the highly malignant gastrointestinal cancers and the third leading cause of cancer death. In the last decade, early gastric cancer (EGC) has been reported by using narrow-band imaging (NBI) magnifying endoscopy. Advances in endoscopic techniques, such as endoscopic submucosal dissection (ESD), have enabled the en bloc resection of these EGC. Although ESD is performed for early gastric cancer, there are still many difficult problems in technique of this procedure. The difficulty of gastric ESD depends on the size and location of a tumor, presence of severe submucosal fibrosis, presence of ulceration... We report a case of our successful ESD by using Clutch cutter and IT knife 2 in treatment of EGC with severe submucosal fibrosis. Case presentation: A 62-year-old man felt an epigastric discomfort two months ago. The narrow-band imaging (NBI) magnifying endoscopy revealed a suspected early gastric cancer type 0 - IIa + IIc (Japanese classification of early gastrointestinal cancers) at the incisura angularis, the size of this lesion was 15 mm in diameter, and pathological result of endoscopic biopsy was a well-differentiated adenocarcinoma. ESD was performed and we found there was severe submucosal fibrosis which was dissected safer and faster by using Clutch cutter and IT knife 2. There were no complications such as severe bleeding and perforation. The size of resected specimen was 60 x 35 mm and the time of procedure was 150 minutes. After ESD, the pathological result was a well differentiated adenocarcinoma, pT1a, UL(-), LY(-), V(-), no cancer cell in vertical and horizontal margins. The healing time of ESD-induced ulcer was 5 weeks without local recurrence. Conclusion: Through this case, we aim to emphasize the importance of using Clutch cutter and IT knife 2 as a modified technique which makes ESD a safe procedure in treatment of EGC with severe submucosal fibrosis.

White Substance

A 75-year-old woman had a 5 mm slightly elevated yellowish lesion in her thoracic esophagus. Narrow-band imaging magnifying endoscopy (NBI-ME) revealed aggregations of a tiny white substance beneath each intrapapillary capillary loop with weaving, dilatation, and a different shape. In this case, an irregular caliber was absent. The biopsy specimen taken from the lesion showed cells with large nuclei and increased chromatin clumping in the basal layer. These cells were positive for p53. Endoscopic submucosal dissection was performed for the purpose of excisional biopsy. Finally, it was diagnosed as an esophageal xanthoma with a benign epithelial reactive inflammation. This is the first report of esophageal xanthoma showing the characteristic NBI-ME finding of esophageal xanthoma. Further studies are required to determine whether the characteristic finding of NBI-ME is generally found in esophageal xanthomas.
