Developments in the technique of sphincter of Oddi manometry and investigation of sphincter of Oddi dysfunction [PDF]
, 1999 MDThe hazardous technique of endoscopic manometry precludes the investigation of "normal volunteers" required to advance our knowledge of the physiology and pathophysiology of the sphincter of Oddi, a suitable animal model is required. Large and small

Automatic localisation of innervation zones: a simulation study of the external anal sphincter [PDF]
, 2009 Traumas of the innervation zone (IZ) of the external anal sphincter (EAS), e.g. during delivery, can promote the development of faecal incontinence. Recently developed probes allow high-resolution detection of EMG signals from the EAS.

A novel animal model of long-term sustainable anal sphincter dysfunction [PDF]
, 2013 Background: Although intersphincteric resection can avoid the need for permanent colostomy in patients with lower rectal cancer, it sometimes causes anal sphincter dysfunction, thus resulting in a lifelong, debilitating disorder due to incontinence of ...
