Endoscopic sleeve gastroplasty and POSE—illustration of different techniques and suturing patterns. On the left, endoscopic sleeve gastroplasty (a, b, c) suturing the antrum. Graus Morales et al. implemented a Z-pattern (c) instead of a triangular pattern (a, b). The Z-shaped running suture with multiple closer stitches aims to reduce suture tension and increase its durability (84). On the right, the POSE targeting the fundus (d), new suturing patterns targeting the antrum have been proposed by Lopez-Nava et al. POSE-2 (16) or distal-POSE by Jirapinyo et al. (85) (e).
