Knife-assisted full-thickness resection guided by pocket detection method for detection and complete excision of deeply invasive rectal cancer

Year: 2024

Type: article

Abstract: A 61-year-old patient with concomitant esophageal (cT2N0M0) and pharyngeal (cT3N2M0) squamous cell cancers under systemic treatment (Charlson Comorbidity Index 4) was referred for a rectal lesion detected on a positron emission tomography scan. Endoscopy showed a sessile 25-mm proximal rectal lesion with a demarcated and slightly depressed central area (Paris 0-Is+IIc, Japan Narrow-Band Imaging Expert Team-3) on the posterior wall (Fig. 1A). Magnetic resonance imaging ruled out extramural vascular and nodal involvement and confirmed the extraperitoneal location of the lesion.
