“…Although an EUS-FNAB with a forward-viewing echoendoscope might be able to overcome scope intubation issues ( 11 ), it would be difficult to pinpoint the target lesion with the narrow scanning range (90°) of such an approach ( 3 ). The overtube and guidewire techniques ( 12 , 13 ) assist with scope intubation, although they are costly. We performed ultra-stiff guidewire-assisted scope intubation using a shallow oblique view (40°) echoendoscope under fluoroscopic and endoscopic guidance ( 3 ).…”

A Transanal Endoscopic Ultrasound-guided Fine-needle Aspiration Biopsy for an Intrapelvic Tumor Diagnosed as Recurrence of a Smooth Muscle Tumor of Uncertain Malignant Potential Following Uterine Morcellation

A transoral endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) is a well-established tissue-sampling method. However, performing a transanal EUS-FNAB remains challenging. Uterine morcellation has emerged as a minimally invasive approach for benign tumor treatment. However, uterine myomas are heterogeneous and include malignant and indeterminate malignant cells. We herein report a rare case of intrapelvic tumor diagnosed by a transanal EUS-FNAB as a recurrence of smooth muscle tumors of uncertain malignant potential following uterine morcellation. Physicians should be aware that a previous uterine myoma resected under morcellation has the possibility of intra-abdominal recurrence. A transanal EUS-FNAB is a practical option for making a pathological diagnosis.

We recently read with great interest a study by Zhang et al in the World Journal of Gastroenterology . In our practice, we focus specifically on examining appendiceal mucinous neoplasms (AMNs) with endoscopic ultrasound (EUS) using different scopes. AMNs are rare neoplastic lesions characterized by an accumulation of mucin inside a cystic dilatation of the appendix. Clinically, they can present as nonspecific acute appendicitis. AMNs can turn into a life-threatening condition, termed pseudomyxoma peritonei, in which the ruptured appendix causes accumulation of mucin in the abdomen. Therefore, accurate and rapid diagnosis of AMN is essential. EUS is able to confirm and stage AMNs; although, EUS examination was once limited to the rectal and anal regions due to the conventional oblique-view scopes. With the emergence of new forward-view linear echoendoscopes and instruments like EUS miniprobes and overtubes, the scope of examination is changing. Herein, we discuss the feasibility of using the curved linear array echoendoscopes to examine cecal and appendiceal orifice lesions.

“…2,3 In 2019, we reported a case of successful fine-needle aspiration (FNA) of a subepithelial lesion in the cecum using a CLA-EUS. 4 The potential use of CLA-EUS in the colon beyond the rectosigmoid area is significant because it can allow tissue sampling and enable EUS-guided interventions in the lower gastrointestinal (LGI) tract. Nonetheless, a standardized technique must be developed to ensure the safety and reproducibility of the procedure.…”

See YouTube Video on our YouTube Channel: https:// youtu.be/L8VDbHrmHWk PRELIMINARY RESULTS: A total of 13 female patients underwent colonoscopic ultrasound. All patients (100%, 13/13) were successfully scanned. Fine-needle aspiration was deemed necessary and successfully performed in 100% (5/5) of the patients. Tissue samples collected by fine-needle aspiration resulted in a diagnostic yield of 60%, and no adverse events resulted from this intervention.CONCLUSIONS: This study demonstrates the feasibility of performing colonoscopic ultrasound with a curvilinear array transducer. Fine-needle aspiration for subepithelial, colonic, and extracolonic lesions is feasible and safe in this setting with no adverse events reported in our study. FUTURE DIRECTIONS: Future research should be directed toward validating colonoscopic ultrasound with a curvilinear array transducer technique in prospective randomized trials. Studies evaluating the feasibility and safety of endoscopic ultrasound-guided interventions in the colon, such as abscess drainage and enteral anastomosis, should be considered.
