Tsib Txoj Kev Txheeb Xyuas Classic - Txheeb Xyuas Tus Kheej

1. Ob npaug -Click / Ob -Pop Sensation (Ob chav-Click / Poob- ntawm-Resistance Sign)

Txoj Cai:​

Lub caij nplooj ntoos hlav stylet yog compressed thaum tho lub anterior rectus sheath → thawj maj mam "nias" los yog tsis kam hloov. Thaum ua txhaum lub peritoneum, tsis kam poob qis → lub caij nplooj ntoos hlav deploys blunt stylet → thib ob audible / tactile "nias."

Tus nqi:​

Daim ntawv tam sim no ntawmtactile tawm tswv yim; ib lub hauv paus ntawm cov kws phais neeg paub txog cov leeg nqaij nco.

Kev txwv:​

Kev kawm siab heev. Fibrotic fascia (kev phais ua ntej), cov phab ntsa hauv plab plab (kev rog), los yog cov rog rog subperitoneal hloov qhov kev xav. Qhov tseem ceeb -txawm tias ob clicks tau hnov, nws tsuas paub tiasob txheej tau hla, tsis yoghais tias lub ntsis yog nyob rau hauv lub free peritoneal kab noj hniav. Lub koob tseem tuaj yeem tso rau hauv:

Omental folds

Adhesion bands

Ua ntej- cov roj peritoneal

📌 Xaus:​ Ob npaug -nias yog atsim nyog qhia, yeej tsis muaj kev lees paub txaus.

2. Aspiration (Negative Pressure) Test

Txheej txheem:​

Txuas ib 5 mL npliag koob txhaj rau Veress koob hub thiab maj mam sim aspiration.

Txhais lus:

Fresh arterial ntshav:Koob yuav nyob rau hauv epigastric artery / aortic ceg / iliac hlab ntsha → tshem tawm tam sim ntawd, thov compression, xaiv qhov chaw tshiab.

Ntshav venous:Muaj peev xwm nkag mus rau hauv IVC tributaries.

Cov ntsiab lus enteric / bile / zis:Visceral perforation (mob plab lossis zais zis).

Cov pov thawj:​

Hauv kev tshawb nrhiav yav tom ntej ntawm 100 tus neeg mob, qhov kev sim siab pom tau pom:

Qhov tshwj xeeb=100%

Negative Predictive Value (NPV)=100%

Ntawd yog: azoonrhiav (ntshav los yog cov ntsiab lus enteric) ntseeg tau tias qhov chaw tsis raug; atsis zoonrhiav (tsis muaj dab tsi aspirated) txhim khu kev cai tawm tag nrho vascular lossis visceral nkag-tab sis nws tsis tuaj yeem ua pov thawj qhov chaw intraperitoneal zoo.

📌 Lub luag haujlwm raug:​ A txoj cai- tawmtest-ibyuam kev detector, tsis atxoj hauj lwm locator.

3. Saline Drop / Hanging Drop Test

Txheej txheem:​

Qhib lub stopcock, tso ib tee ntsev ntawm lub hub (los yog muab ib tug saline - puv syringe yam tsis plunging). Maj mam nqa lub plab phab ntsa.

Qhov zoo:Poob yog "sucked" rau hauv lub hub → qhia tias tsis zoo siab los ntawm lub peritoneal kab noj hniav.

Tsis zoo:Tso tseg tseem nyob ruaj ruaj los yog refluxes.

Theoretical hauv paus:​

Cov kab noj hniav ib txwm tswj hwm qhov tsis zoo siab me ntsis rau cov huab cua, tshwj xeeb tshaj yog thaum kev tshoov siab.

Cov pov thawj:​

rhiab heev ≈50%, Tshwj xeeb =100%, NPV =94.7%

Txhais lus:

Tsotxav sab hauv→ sib haum nrog cov kab noj hniav, tab sis tsis muaj pov thawj (omentum lossis adhesion capsule kuj tuaj yeem cuam tshuam tsis zoo)

Tsotsis txav→ tsis kavKev tso kawm kom raug (adhesion lossis omental foob hla sab chaw nres nkoj thaiv kev sib kis)

📌 Clinical kev muaj tiag:Tseem tau qhia raws li tus qauv txheej txheem hauv ntau qhov kev cob qhia, tab sis nws yuav tsum tau txhais raws litxhawb nqa cov ntaub ntawv pov thawj, tsis yogpov tseg. Tsis txhob tso tseg ib tug zoo -loj koobnkaus xwbvim qhov poob tsis txav; yeej tsis pib insufflationnkaus xwbvim nws ua.

4. Txhaj-Rov qab (Inject-Aspirate) Test

Txheej txheem:​

Txhaj 2–3 mL ntawm saline los ntawm rab koob → sim rov qab - aspirate.

Txhaj tau yooj yim, tsis tuaj yeem nqus tau:Qhia kom dispersion rau hauv lub peritoneal kab noj hniav →sib haum nrogmuab tso rau qhov tseeb.

Full ntim aspirated rov qab:Qhia tias lub tswv yim yog nyob rau hauv aqhov chaw kaw(pre-peritoneal hnab ris los yog adhesion-encapsulated kab noj hniav) →qhia qhov chaw tsis raug.

Kev txwv:​

Cov kev tshawb fawb qhia tau tias muaj kev nkag siab tsawg rau kev tshawb nrhiav qhov chaw tsis raug. Txawm tias "txhaj tshuaj OK, tsis rov qab" tuaj yeem tshwm sim yog tias lub plab zom mov nyob ib puag ncig lub taub.

5. Initial Insufflation Pressure Monitoring - Tam sim no "Gold Standard"

Nov yog ib qho kev ntsuam xyuas uas ntseeg tau tshaj plaws:

Txuas lub koob Veress rau lub insufflator.

Teem flow rauqis (tsawg dua lossis sib npaug li 1 L / min).

Sau cov ntawv nyeem siab tshaj thawj 15-25 vib nas this (feem ntau 5 nyeem ntawm ~ 5-thib ob lub sijhawm).

Txhais lus:

Txhua qhov kev nyeem tsawg dua lossis sib npaug li 8-10 mmHg​ → >99% muaj feem yuav raug tso rau hauv lub cev; ua ntej-peritoneal insufflation yuav tsis zoo heev.

Sustained high pressure (>10-12 mmHg)nrog dej tsis zoo → qhia:

Ua ntej- txoj haujlwm peritoneal

Lub tswv yim cuam tshuam rau omentum / plob hau

Ib nrab luminal obstruction

Tsis tshua muaj siab tab sis tsis muaj mob plab + audible hissing ntawm caj dab→ tau koob retraction rau hauv cov ntaub so ntswg subcutaneous (thaum ntxov subcutaneous emphysema)

Cov pov thawj tseem ceeb (Teoh et al.):​

Thaum lubthawj tsib qhov kev nyeem ntawv sib law liag tau tag nrho<10 mmHg, tsis pom muaj tus kab mob ua ntej-peritoneal insufflation-ua qhov no yog ib qho pov thawj uas muaj zog tshaj plaws - raws li kev xeem tam sim no.

Txoj Kev Ua Zoo Tshaj Plaws: Multimodal Hla-Kev Tshawb Fawb (Tus Hla-Check Protocol)

Kev coj ua tiag tiag yogyeej tsis"xaiv koj qhov kev sim nyiam" tab sis theej ib txheej txheej:

Kauj Ruam 1 - Txiav tawm kev puas tsuaj:​

→ Aspiration test (kom tsis txhob nyob hauv nkoj / viscus)

Kauj Ruam 2 - Tsim kev ntseeg siab:​

→ Ob npaug - nyem tactile tawm tswv yim + saline drop test (txhawb, tsis txiav txim siab)

Kauj Ruam 3 - Kev txiav txim siab meej:​

→ Tsawg- ntws pib lub siab nkhaus (cov ntaub ntawv lub cev lub cev)

Txhua tus chij liab​ (blood on aspiration / pressure >10 mmHg tsis muaj kev cuam tshuam / tsis muaj peev xwm insufflate) →nres, thim rov qab, rov ntsuas dua, tsis txhob yuam insufflation.

Advanced Horizons: Mus rau "Lub Hom Phiaj Thib Peb Qhov Muag"

Cov technologies uas tshwm sim (txawm tias tseem tsis tau muaj tus qauv) muaj xws li:

Impedance / dielectric sensors​ nyob rau hauv lub koob taub (qhov txawv ntawm cov ntaub so ntswg los ntawm bio-impedance)

Ua ntej - scanning nrog ultrasoundrau daim ntawv qhia adhesions thiab xaiv qhov kev nkag siab zoo

Optical (fiber) Veress koob​ tso cai rau ib nrab- pom kev ncaj qha thaum kev nce qib

Cov no tseem tab tom tshawb nrhiav tab sis tseem muaj feem cuam tshuam hauvsiab - cov xwm txheej txaus ntshai: hnyav adhesions, cachexia heev, los yog keeb kwm ntawm omentopexy / extensive laparotomy.
