Objectives. - To evaluate the educational interest of a workshop on diagnosis and repair of obstetric anal sphincter injuries (OASIS). To evaluate the theoretical and anatomical knowledge of OASIS repair by French residents in obstetrics and gynecology.

Materials and methods. - The workshop was composed of slides, video of repair and training using cadaveric sow’s anal sphincters. All subjects were tested with a questionnaire before and after the course.

Results. - Thirty residents participated. Classification of OASIS was known by 13.3% of the residents before the training versus 93.3% after the workshop (P < 0.001). Initially, only 6.7% correctly classified operative procedures of OASIS versus 86.7% after the workshop (P < 0.001). Per pre-test, 90% of residents did not know how to identify the internal anal sphincter (IAS) versus 3% at post-test (P < 0.001). Seventy percent of trainees correctly identified the external anal sphincter (EAS) at the beginning of training. Before the course, no resident knew the repair of the IAS and only one third knew the technical repair of the EAS. After the workshop, the theoretical knowledge of EAS and IAS repair were acquired by all (P < 0.001).

Conclusion. - Structured hands-on training improves significantly the knowledge of OASIS diagnosis and repair. (C) 2013 Elsevier Masson SAS. All rights reserved.
