TI  - Wide disparities in attitudes and practices regarding Type II sphincter of Oddi 
      dysfunction: a survey of expert U.S. endoscopists.

AB  - BACKGROUND: Sphincter of Oddi manometry (SOM) is recommended in the evaluation of 
      suspected Type II sphincter of Oddi dysfunction (SOD2), though its utility is 
      uncertain. Little is known about the practice of expert endoscopists in the 
      United States regarding SOD2. METHODS: An anonymous electronic survey was 
      distributed to 128 expert biliary endoscopists identified from U.S. advanced 
      endoscopy training programs. RESULTS: The response rate was 46.1 % (59/128). Only 
      55.6 % received training in SOM, and 49.2 % currently perform SOM. For biliary 
      SOD2, 33.3 % routinely obtain SOM, 33.3 % perform empiric sphincterotomy, and 
      26.3 % perform single session endoscopic ultrasound/endoscopic retrograde 
      cholangiopancreatography (EUS/ERCP). In contrast, an equal number (35.1 %) favor 
      SOM or single session EUS/ERCP for suspected acute idiopathic recurrent 
      pancreatitis, while 19.3 % would perform empiric sphincterotomy. Those who 
      perform SOM believe it to be important in predicting response to treatment 
      compared with those who do not (71.8 % vs 23.1 %, P = 0.01). Yet only 51.7 % of 
      this group performs SOM for suspected SOD2. Most (78.6 %) believe that < 50 % of 
      patients report improvement in symptoms after sphincterotomy. Common reasons for 
      not obtaining SOM included unreliable results (50 %), and procedure-related risks 
      (39.3 %). Most (59.3 %) believe SOD2 is at least in part a functional disorder; 
      only 3.7 % felt SOD is a legitimate disorder of the sphincter of Oddi. 
      CONCLUSIONS: Our survey of U.S. expert endoscopists suggests that SOM is not 
      routinely performed for SOD2 and concerns regarding its associated risks and 
      validity persist. Most endoscopists believe SOD2 is at least in part a functional 
      disorder that will not respond to sphincterotomy in the majority of cases.
