What are the critical points of the proctological examination today? We can only detect the morphological aspects of the anus and the rectum but not their functionality. We can only detect the morphological aspects of the anus and the rectum but not their functionality. At present, a device does not exist that, already at the first visit, allows us to supect the presence of attendant diseases and also to predict postoperatory complications. At present, a device does not exist that, already at the first visit, allows us to supect the presence of attendant diseases and also to predict postoperatory complications. Guidelines do not exist that provide for the anorectal manometry in patients with minor diseases (mucosal rectal prolaps and/or haemorrhoids).

My own study: 218 patients Jan / Sept The rectal sensitivity thresholds are the same with MFA and anorectal manometry.The rectal sensitivity thresholds are the same with MFA and anorectal manometry. The RST alterated values, detected with the MFA during the first visit, could be an expression of attendant diseases and they could predict post- operatory complications.The RST alterated values, detected with the MFA during the first visit, could be an expression of attendant diseases and they could predict post- operatory complications. To demostrate that: 189 patients: 128 PMRE; 61 ODS

FSDDV MTV First aim. The correlation on the three parameters related to the measures detected with MFA and manometry, is very high (R= Pearsons correlation coefficient). By Biostatistic Unit of tha Genova University – Doctor Mariapia Sormani. Rectal sensitivity thresholds are the same if detected with MFA or anorectal manometry (R = 0,99 p<0,001).

Complication: the urgency (DU) Temporary (TU) Permanent (PU) Severe (SU) UD that resolves itself within three weeks without consequences that continues up to three months but also resolves itself without consequences that lasts more than three months and shows itself in an increase of the daily evacuations but the urgency decreases or disappears completely.

There is an important correlation between hypersensitivity and Permanent Urgency (p=0.02), between hypersensitivity and Severe Urgency (p=0.01) and not so important between hypersensitivity and Temporary Urgency (p=0.07).
