“…These new methods include suck-ligate-unroof-biopsy (SLUB) 11, block biopsy via submucosal endoscopy with a mucosal flap method (SEMF) 12 13, mucosal cutting biopsy 14, and endoscopic partial resection with the unroofing technique (EPR-UT) 15. SLUB is a cap-based technique that involves suctioning the tissue into a cap and subsequently tightening a detachable loop to ligate the lesion.…”

“…However, a meta-analysis that examined the diagnostic yield and complication rates of EUS-FNA, TCB, and EUS-FNB for patients with gastrointestinal stromal tumors (GIST) demonstrated no significant differences between the techniques 10. To improve diagnosis of SELs, several new tissue acquisition methods have been proposed, including suck-ligate-unroof-biopsy (SLUB) 11, use of endoscopic submucosal dissection (ESD) technique 12 13 14, endoscopic partial resection with unroofing technique (EPR-UT) 15, and single-incision needle-knife (SINK) biopsy 16. When performing SINK, the overlying mucosa of a SEL is opened with a single linear incision using a standard needle knife and tissue samples are obtained by passing conventional biopsy forceps through the opening and deep into the lesion.…”

Background and study aims Single-incision needle-knife (SINK) biopsy is a diagnostic method for acquiring tissue samples for subepithelial lesions (SELs). A single linear incision is made in the overlying mucosa and tissue samples are obtained by passing conventional biopsy forceps through the opening and deep into the lesion. The aim of this study was to describe the efficacy and safety of this technique. Patients and methods Consecutive patients who underwent SINK biopsy for an upper gastrointestinal SEL between October 2013 and September 2015 were retrospectively reviewed. Results Forty-nine patients underwent 50 SINK biopsies. Sufficient sampling for a definite pathologic diagnosis was obtained in 42 (86 %) cases, with 91 % (40/44) having sufficient sample to perform immunohistochemistry when deemed clinically relevant. Of the 26 patients with prior non-diagnostic biopsies or FNA, a specific diagnosis was obtained in 85 % (22/26). There were no significant adverse events. Conclusions SINK biopsy is a safe and feasible strategy for obtaining a definitive tissue diagnosis with immunohistochemistry for SELs.

“…However, it might be more difficult to obtain tissue from a lesion located in extraluminal regions. 29,[33][34][35] Recently, new endoscopic resection techniques, including laparoscopic endoscopic cooperative surgery, 36 endoscopic full-thickness resection, and endoscopic submucosal tunnel dissection were developed. These techniques are safe and effective for small GISTs.…”

“…Recently, several diagnostic techniques, such as EUS‐guided fine‐needle aspiration (EUS‐FNA), EUS‐guided trucut biopsy (EUS‐TCB), and other biopsy techniques based on endoscopic mucosal resection or endoscopic submucosal dissection (ESD), have emerged as methods for samples of SELs to theoretically overcome the disadvantages of EUS . However, current studies demonstrated that EUS‐FNA had variable diagnostic yields of 38–82% because of inadequate tissue acquisition, whereas EUS‐TCB was limited by technical constraints such as angulation caused by the stiffness of the device .…”

Background and Aim The effect of real‐time analysis of needle‐based confocal laser endomicroscopy (nCLE) for gastric subepithelial lesions (SELs) on the diagnostic value is unclear. The study aimed to investigate the diagnostic efficacy of real‐time nCLE for gastric SELs and to assess the technical aspects and safety of real‐time nCLE. Methods Consecutive patients with gastric SELs ≥ 1 cm were prospectively investigated by endoscopic ultrasound (EUS), followed by nCLE. During EUS‐nCLE, real‐time nCLE diagnosis was made by an expert endoscopist. The procedure‐relative adverse events were assessed and recorded. One‐month washout period later, nCLE videos were reviewed off‐line by the same endoscopist. The nCLE diagnoses were compared with corresponding pathological results. Additionally, image quality and interobserver agreements for the criteria were evaluated by three experienced endomicroscopists. Results Except for one failing to be punctured, 60 patients completed EUS‐nCLE procedures successfully. Real‐time nCLE had high diagnostic accuracies of ≥ 88.3% for gastric SELs. There were no significant differences between real‐time and off‐line nCLE diagnoses for gastric SELs (P > 0.05). The overall accuracy of real‐time nCLE for diagnosis of gastric SELs was 86.7%. There were no procedure‐relative adverse events occurred. In addition, the mean image quality score was 3.6 (1 = poor and 5 = excellent). The interobserver agreement was “almost perfect” for ectopic pancreas and “substantial” for gastrointestinal stromal tumor, leiomyoma, and carcinoma. Conclusions Endoscopic ultrasound‐nCLE could provide in vivo real‐time diagnostic imaging with a high diagnostic accuracy. Meanwhile, real‐time nCLE was feasible and had a satisfactory safety profile.
