Post-sleeve stenosis may be avoided by the judicious use of peroperative endos­copy. Nimeri et al. [10] demonstrated that with this strategy the incidence of stenosis may drop from 3.2 to 0%. Possible mechanisms resulting in better out­comes—as mentioned by the authors—included the ability to detect and remove ill placed sutures covering the staple line, or to address stapling errors such as staples placed too close to the incisura, Of note, Nimeri et al. mentioned that short steno­sis created by stapling flaws may be addressed by an immediate short seromyot­omy, a technique that will be described later. In one Italian study, it appeared that oversewing the staple line was accompanied by a significant increase of stenosis rate, while it did not improve bleeding and fistula prevalence [10]. This experience has recently been duplicated [9].
