Yr Athro Simon Emery o Fwrdd Iechyd Abertawe Bro Morgannwg oedd yn cadeirio'r grŵp ac roedd yr aelodau’n cynnwys clinigwyr ac academyddion o'r meysydd wro-gynaecoleg, llawdriniaethau'r colon a'r rhefr, gofal sylfaenol, gofal iechyd annibynnol, ffisiotherapi, rheoli ymataliaeth a phoen. Dewisodd cynrychiolwyr y cleifion beidio ag ymuno â'r grŵp ond rwyf wedi cyfarfod â chynrychiolwyr o Grŵp Goroeswyr Triniaethau Rhwyll Cymru a chafodd yr wybodaeth yr oeddynt hwy am ei rhannu â mi ei hanfon ymlaen at y grŵp i’w hystyried.
The group was chaired by Professor Simon Emery from Abertawe Bro Morgannwg Health Board and was made up of clinicians and academics in the area of uro-gynaecology, colorectal surgery, primary care, independent healthcare, physiotherapy, continence and pain management.  Patient representatives chose not to join the group but I have met with representatives of the Welsh Mesh Survivors Group and information they chose to share with me was forwarded for full consideration by the group.
