Stepwise organ-preserving management of incidental pT1 rectal adenocarcinoma: outcomes after completion transanal endoscopic microsurgery (TEM).
[BACKGROUND] Accurate in vivo assessment of rectal lesion invasion remains challenging despite advances in high-definition endoscopy and AI-assisted diagnostics. Some lesions resected endoscopically for presumed superficial pathology are ul…

Transanal endoscopic microsurgery (TEM) for rectal GI stromal tumour.
[BACKGROUND] Rectal gastrointestinal stromal tumours (GIST) are uncommon and technically challenging to treat due to the confined pelvic anatomy and proximity to the anal sphincter complex. The oncological goal of surgery is R0 resection, b…

Peritoneal opening during transanal endoscopic microsurgery: can preoperative positioning assessment improve intraoperative management?
[BACKGROUND] Peritoneal opening (PO) during transanal endoscopic microsurgery (TEM) can cause the pneumorectum to collapse and complicate the procedure. As indications expand to larger, more proximal rectal lesions, understanding the real-w…

Which prognostic factors for recurrence after transanal endoscopic microsurgery for early rectal cancer?
[BACKGROUND] Transanal endoscopic microsurgery (TEM) enables the local excision of rectal neoplasms with minimal invasiveness; however, the long-term oncologic safety for pTis and pT1 lesions, as well as the significance of traditional hist…

Diagnostic accuracy of 1,000 endorectal ultrasounds before transanal endoscopic microsurgery for rectal neoplastic lesions.
[INTRODUCTION] Endorectal ultrasound (EUS) is an essential tool for local staging of rectal neoplasia; however, its diagnostic accuracy in distinguishing non-invasive from invasive lesions before transanal endoscopic microsurgery (TEM) rema…
