BACKGROUND AND AIMS: Aim of this study is to compare a specific kind of biopsy forceps to a traditional one in providing an adequate specimen of esophageal pemphigus vulgaris lesions that includes the basement membrane for definitive diagnosis.
PATIENTS AND METHODS: Prospective, randomized, blind, single-center study. We performed upper endoscopy with biopsy in 32 patients divided into two groups of 16 each: in group A with a commercially available standard biopsy forceps while in group B with a commercially available rocking biopsy forceps. Hundred-ninety-six biopsy specimens from both groups were blindly evaluated by the same pathologist.
RESULTS: In group A 18.8% of biopsy specimens were adequate (basement membrane included). In group B 87.5% of biopsy specimens were adequate. The presence of the entire thickness of the mucosa was significantly higher in group B compared to group A. All parameters typically taken into account by pathologist for diagnosis of esophageal pemphigus vulgaris were significantly improved in group B.
CONCLUSIONS: The biopsy forceps used in group B permits a rocking motion of the tip on contact with the mucosa, produces a deeper full-thickness mucosal sample up to the basement membrane and assists in the evaluation of histologic features of esophageal pemphigus vulgaris.
