Summary

Tab af peritoneal integritet giver et nyt paradigme til at forstå og behandle kroniske bækkensmerter hos kvinder med milde former for endometriose og let kan afsløres ved hjælp af intraoperativ instillation af farvestof på tidspunktet for laparoskopi.

Abstract

Endometriose er en almindelig sygdom, der påvirker 40 til 70% af reproduktive-alderen kvinder med kroniske bækkensmerter (CPP) og / eller infertilitet. Formålet med denne undersøgelse var at demonstrere anvendelsen af ​​et blåt farvestof (methylenblåt) at farve peritoneale overflader under laparoskopi (L / S) til at detektere tabet af peritoneal integritet hos patienter med bækkensmerter og formodede endometriose. Fyrre kvinder med CPP og 5 kvinder uden smerte blev evalueret i denne pilotundersøgelse. I L / S, blev koncentreret farvestof sprøjtet på peritoneale overflader, derefter aspireret og skyllet med Lactated Ringers opløsning. Områder med lokaliseret farvestofoptagelse blev bedømt for tilstedeværelsen af ​​synlige endometriske læsioner. Områder med intens peritoneal farvning blev resektion og nogle fikseret i 2,5% bufret glutaraldehyd og undersøgt ved scanning (SEM) elektronmikroskopi. Blå farvestofoptagelse var mere almindelig hos kvinder med endometriose og kroniske bækkensmerter end kontrol (85% vs 40%). Resektion af det blå staivelafgrænsede områder afslørede endometriose ved SEM og tab af peritoneal celle-cellekontakt sammenlignet med normale, ikke-farvende peritoneum. Berørte peritoneum var forbundet med synlige endometriske implantater i de fleste, men ikke alle patienter. Subjektiv smertelindring blev rapporteret i 80% af deltagerne. Baseret på scanningselektronmikroskopi, konkluderer vi, at endometriske celler går langt ud over synlige implantater af endometriose og synes at forstyrre den underliggende mesothelium. Subtle læsioner af endometriose kan derfor forårsage bækkensmerter ved afbrydelse af peritoneal integritet, så menstruation eller ovulatoriske blod og tilhørende smerter faktorer adgang til de underliggende sensoriske nerver. Komplet resektion af berørte bughinde kan give en bedre langsigtet behandling for endometriose og CPP. Denne simple teknik synes at forbedre afsløring af subtile eller nær usynlig endometriose hos kvinder med CPP og minimal visuelle resultater ved L / S og kan tjene til at ophøje diagnostisk præcision for endometrioseved laparoskopi.

Protocol

1. Patient Selection Kvinder med kroniske bækkensmerter gennemgå en historie og fysisk eksamen. Lokalisering af smerte, timing med hensyn til menstruationscyklus, associerede symptomer, herunder irritabel tarm klager eller blære klager noteres og registreres. Kvinder, der gennemgår laparoskopi er tilladt til eventuel resektion af endometriose og brug af deres væv til forskning. 2. Laparoskopiske teknikker Laparoskopi udføres under anvende…

Representative Results

Et eksempel på subtil endometriose, der var næsten usynlige er vist i figur 1A. Før påføring af blåt farvestof en uregelmæssig område med stiplede peritoneum blev værdsat hjulpet af refleksion af laparoskopisk lys. I figur 1B, viser udseendet af dette samme område efter farvning samme uregelmæssigt mønster over blæren (figur 1 B). Når denne del af peritoneum blev resekteret (figur 1C) blev underkastet SEM, som viser overliggende endometris…

Discussion

Kronisk bækkensmerter hos kvinder er en bekostelig og dårligt forstået problem 1. Dysmenoré er den mest almindelige form for bækkensmerter påvirker 60% af kvinder 2 og 72% af unge 3. Endometriose er en inflammatorisk sygdom, der rammer 5% af normale kvinder, men er til stede i op til 70% af kvinder med bækkensmerter. Mens endometriose bidrager til kroniske bækkensmerter (CPP), en mekanisme, hvormed læsioner forårsager smerte fortsat usikkert 4. Paradoksalt nok er gra…
