Presentation Transcript

  1. Esofagul • Conduct musculo-membranos • Superior-marginea inf a cartilagiului tiroid (C6) • Inferior – cardia (T10, T11) • Pars • Cervicalis (5-8 cm) • Toracalis (16-20) • Abdominalis (2,5-3cm)

  2. Anatomie • 3 stramtori: • Cricofaringiana: m. cricofaringian si cricoid, rezistenta scazuta (Zenker) • Bronho-aortica: arcul aortic si bronhia principala stg (2 cm mai jos) • Diafragmatica: diafragmul

  3. Raporturi • Pars cervicalis: • traheea, tiroida, n. recurentstg (anterior) • Tesutconjunctiv, coloana (posterior) • Vaselegatului, n. recurent dr., a. subclaviedr (lateral) • Pars toracalis: • Traheea, bronhiastg, atriulstg, n X stg (anterior) • Coloana, aorta descendenta, n. X dr (posterior) • Pleura, n recurent, originea a carotidestg, (lateral) • Pars abdominalis: • Peritoneu, lob hepatic stg (anterior) • A. diafragmaticastg (posterior) • Fornixul gastric (lateral)

  4. Anatomie • Artere: • Tiroidiana inferioara, eso-traheala, bronsice, esofagiene • Vene: • Dreneaza in vena azygos (sup) si splenica (inf) • Limfatice: • Parajugulari, paratraheali, mediastinali post • Nervi: • Simpatic (ggl paravertebrali), parasimpatic (n X)

  5. Malformatii • Diafragmele membranoase (imperforatia) – rar • Atrezii – partiale sau complete (cordon dur fibros) • Brahiesofagul – esofag scurt • Disfagia lusoria – a. subclavie dr. ce isi are originea in aorta si comprima fata post a esofagului

  6. Traumatisme • Organ bine protejat • Plagi • Perforatii • Rupturi • Spontana • Corp strain • Hematomul

  7. Afectiuni inflamatorii • Esofagita peptica (actiunea coroziva a sucului gastric) • Esofagita coroziva • Acuta • Cronica (stenoza esofagiana postcaustica) • Tratament: • Urgenta (combaterea socului, neutralizarea causticului, antibioterapie) • Precoce (micsorarea tendintei formarii cicatricei – cortizon, vitamine) • Tardiv (se adreseaza stenozei)

  8. Corpii straini • Factori favorizanti: tahifagie, tulburari de sensibilitate, afectiuni psihice, edentatia • Involuntar/voluntar (detinuti) • Diferite forme (ascutiti, rotunzi etc) • Starea initiala e esofagului • Evolutia - spre perforatie • Tratament: • Nu se produce voma, impingere in stomac • Esofagoscopie (rigida/flexibila) sau chirurgical

  9. Tumori • Benigne: • Fibrom, polip, papilom, miom, angiom • evolutie lenta • Maligne: • Barbati 40-60 de ani • Ereditatea, fumat alcool, stenoze postcaustice • Carcinom scuamos, adenocarcinom, sarcom
