На основании того, что можно отыскать в литературе, предполагаю, что имеется в виду техника наложения шва по Султану (с перекрыванием тканей), описанная вот в этой публикации (в бразильском журнале, кстати):

На эту работу довольно много ссылок вот такого типа:
In 1999, Sultan and coworkers reported improved results by suturing the IAS and EAS separately [4]. During reconstruction of anal atresia in pediatric surgery, both the EAS and IAS are divided along the dorsal midline for access to the rectum (posterior sagittal transsphincteric plastic) [8]. They are then sutured back again end-to-end, layer by layer, with good long-term results.

The intestinal structures were put in place and the linea alba was
closed with an interrupted inversed Sultan suture pattern
using double 2 USP polyglactin 910 (Polysorb®, Vétoquinol
S.A., Paris, France).
