“…Akahoshi et al used the single-cannula-assisted technique mentioned above for the fine-needle aspiration of a descending colon schwannoma [ 4 ]. Trikudanathan et al reported a case of a schwannoma at the splenic flexure of the colon [ 30 ]. Schwannomas are hard in texture and often originate from the third and fourth layers of an ultrasound (muscularis propria) [ 31 ].…”

“…Due to the multiple physiologic curvatures in the sigmoid colon, advancing a linear-array ultrasound endoscope relying solely on endoscopic vision and ultrasound images is dangerous and prone to perforation. Reviewing all available cross-sectional images of the pelvis is critical to evaluating the left colon and excluding large diverticula before advancing a linear EUS scope [ 30 ]. Subsequently, a suitable echoendoscope is chosen or auxiliary equipment is used to complete the puncture.…”

Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/FNB) is very safe and has a high diagnostic rate for upper gastrointestinal lesions, especially pancreatic lesions, but its application in the lower gastrointestinal tract has rarely been reported. Due to the tortuous course of the colorectum, with the sigmoid colon particularly prone to perforation, most endoscopists are reluctant to perform lateral-sector endoscopic ultrasound scanning without a water-bag protection for the puncture. The ultrasonic endoscopy and flexible puncture needle techniques recently introduced into clinical practice have made ultrasound-guided puncture safer and more convenient. In addition, endoscopists have carefully tested various protective measures to improve the safety of the lower gastrointestinal puncture, substantially increasing its clinical feasibility. In this article, we review the iterations of endoscopic ultrasound equipment introduced in recent years and the many ingenious ideas proposed by endoscopists regarding lower gastrointestinal puncture.

“…EUS has been described in the assessment of splenic masses but utilization consisted of fine-needle aspiration [5,8]. Use of core biopsy needles for EUS-guided SB allows for acquisition of larger samples, and enables histological analysis and immunochemical staining [7].…”
