I-pHmetry ihambelana nesilinganiso se-asidi (pH) yesilinganiso. Kwezokwelapha, i-pHmetry isetshenziselwa ukuxilonga nokuhlola ubukhulu besifo se-reflux se-gastroesophageal (GERD). Lokhu kubizwa ngokuthi yi-esophageal pHmetry.

I-GERD yisimo lapho okuqukethwe okune-asidi esiswini kunyukela phezulu, okubangela ukusha futhi kungalimaza ulwelwesi lwe-esophagus. Kuvame kakhulu ezinganeni nasezinganeni ezincane.

Isilinganiso se-pH esophageal siyenziwa:

• ukuqinisekisa ukutholakala kwesifo se-reflux se-gastroesophageal (GERD);
• ukubheka imbangela yezimpawu ze-reflux ze-atypical, njengokukhwehlela, ukushuba, umphimbo obuhlungu, njll.;
• Uma i-anti-reflux therapy yehluleka, ukulungisa kabusha ukwelashwa ngaphambi kokuhlinzwa kwe-anti-reflux.

Isivivinyo sifaka ukulinganisa i-pH yomphimbo ngesikhathi esithile (imvamisa esikhathini samahora ayi-18 kuye kwangama-24). Le pH ivamise ukuba phakathi kuka-5 no-7; ku-GERD, uketshezi olunesisu esine-asidi oluningi lunyusa isisu bese lwehlisa i-pH. I-acid reflux iqinisekiswa lapho i-pH esophageal ingaphansi kwe-4.

Ukukala i-intra-esophageal pH, a phenyo ezorekhoda i-pH amahora angama-24. Lokhu kuzokwenza ukuthi kunqume ubunzima be-reflux nezimpawu zayo (emini noma ebusuku, ukuxhumana nezimpawu ezizwakalayo, njll.).

Kudingeka ukuthi uzilile ukuhlolwa. Ukwelashwa nge-anti-reflux kufanele kumiswe ezinsukwini ezimbalwa ngaphambi kokuhlolwa, njengoba kuqondiswa ngudokotela.

Uphenyo lwethulwa ngekhala, kwesinye isikhathi ngemuva kwe-nasal anesthesia (lokhu akuyona into ehlelekile), futhi lududulwa ngomusa ngesisu. Ukwenza lula ukuqhubeka kwe-catheter, isiguli sizocelwa ukuthi sigwinye (isibonelo ngokuphuza amanzi ngotshani).

Uphenyo lunamathiselwe kuphiko lwekhala ngosimende futhi luxhunywe ebhokisini lokuqopha eligqokwe ebhande noma esikhwameni esincane. Isiguli singaya ekhaya amahora angama-24, silandele imisebenzi yabo ejwayelekile futhi sidle ngokujwayelekile. Ipayipi le-catheter alibuhlungu, kepha lingakhathaza kancane. Kuyacelwa ukuthi uqaphele izikhathi zokudla nezimpawu okungenzeka zizwakale. Kubalulekile ukuthi ungalitholi icala limanzi.

Udokotela uzohlaziya isilinganiso se-pH ukuqinisekisa ubukhona nobukhulu besifo se-reflux se-gastroesophageal (GERD). Ngokuya ngemiphumela, ukwelashwa okufanele kunganikezwa.

I-GERD ingelashwa ngemithi elwa ne-reflux. Kuningi, njenge-proton pump inhibitors noma ama-H2 blocker.
