 EUS-FNA is now considered to be the usual method of sampling; however, the diagnostic yield is low: 38 to 82 . Moreover, EUS-FNA often provides insufficient specimens which may not allow for immunohistochemistry that is often essential for diagnosis . Thus EUS-CNB has been assessed for the purpose of obtaining a core sample which allows for histological assessment. Published data reveals a diagnostic though not histologic yield using EUS-CNB of 75 In 2011, the SINK technique for sampling was presented with a reported diagnostic accuracy of 92.8 8. The technique utilizes a conventional needle-knife connected to an electrosurgical unit. A 6 to 12-mm mucosal incision is made over the lesion. Then conventional biopsy forceps are introduced to obtain 3-5 samples. Subsequently, the incision is closed with 2 to 3 endoclips.
