Discussion page at Re: Proper terming of "Abnormality of X (body structure)".

After reviewing HPO content that generated this issue: We will be looking to add these concepts as "Structural abnormality of X" for precision for HPO terms that refer to morphology. For those HPO concepts that group both functional and structural abnormalities, they will be left in that form, e.g. HPO - Abnormality of the gastrointestinal tract has subtypes "Abnormal gastrointestinal tract morphology" and "Functional abnormality of the gastrointestinal tract".

The analysis paper: Review of 48537004 |Bypass graft (procedure)| v0.2.0 is attached to this agenda. 

Previous discussion resulted in suggested edits to the following revised definitions:

• CONSTRUCTION OF BYPASS. Surgical creation of a passage to carry contents
  around a part of a structure in its normal route and back to a structure in its
  normal route.
• CONSTRUCTION OF BYPASS USING GRAFT. Surgical creation of a passage, using a
  biological or synthetic material, to carry contents around a part of a structure in its
  normal route and back to a structure in its normal route.
• CONSTRUCTION OF SHUNT. Surgical creation of a passage allowing contents to
  move from one structure to another, not following its normal route.
• CONSTRUCTION OF SHUNT USING GRAFT (SYN: INTERPOSITION SHUNT). Surgical
  creation of a passage using a biological or synthetic material, allowing contents to
  move from one structure to another, not following its normal route.
• INTERPOSITION GRAFT. A surgical reconstruction, using a biological or synthetic graft, of a
  structural defect to allow for a tension-free anastomosis.
• ANASTOMOSIS. Surgical procedure to create a connection between two tubular or hollow anatomic structures.

It was also proposed that the concepts 360021005 |Bypass - action (qualifier value)| and 424208002 |Shunt - action (qualifier value)| would be inactivated.  However, upon further testing, there were situations where the use of these two concepts were useful.  Alternative solutions are provided.

An analysis document "Endoscopy, endoscopic procedure and related procedures is attached for discussion.  The consistent distinction between and endoscopy and an endoscopic procedure is inconsistently represented as the initial distinction was made based on whether a procedure other than visualization was performed.  This is a difficult distinction to make as it is unknown when an endoscopy is performed whether an additional procedure will be added (such as a biopsy).  The proposal seeks to eliminate this false distinction as well as propose other modeling changes for this hierarchy.

An analysis document "Review of the replacement procedure hierarchy" is attached for discussion.  The issues related to the use of a single concept "Replacement - action" to model replacement procedures are discussed an alternative modeling constructs proposed.

Conversion procedures primarily in the orthopedic space have been historically represented as two separate concepts: i.e. "Conversion from X" and "Conversion to X".  This mimics the approach taken in OPCS4 adn was done ostensibly to prevent a large combinatorial explosion of terms that represented both aspects of a conversion procedure.  Recently SNOMED International has received requests for combined conversion procedures (e.g. Conversion from X to Y").  There are currently:

39 "conversion from" orthopedic concepts

44 "conversion to" orthopedic concepts

There are also conversion procedures related to laparoscopy where a procedure is converted from laparoscopic to open, as well as other procedures unrelated to the orthopedic domain.
