    • Laparoscopia Diagnostica - Operativa• Sterilità• Dolore pelvico cronico, acuto• Gravidanza ectopica• Aderenze, endometriosi• Masse annessiali• Isterectomia (LAVH, TLH, LSH)• Miomi uterini• Patologia del pavimento pelvico• Oncologia ginecologica
    • Laparoscopia: accesso• Inserimento ago di Veres• Inserimento trocar secondo tecnica classica• Inserimento trocar secondo tecnica diretta• Open laparoscopy• Trocar ottico• Introduzione trocar accessori
    • Complicanze maggiori dovute all’accesso Garry R.

    • Diagnosi di Fattore tubarico di Sterilita’ Quale metodica?Quando?
    • Medicina basata sulla EVIDENZA• Two million articles per year in the biomedical literature• A physician should read 19 articles per day, 365 days per year, to keep up with her/his specialty Sackett DL, BMJ 1995
    • NICE guidelines www.nice.org.uk
    • NICE guidelinesMeta-analysis based on three studies with judgement oflaparoscopy without knowledge of HSG results gave pooledestimates of sensitivity and specificity for HSG as a test fortubal obstruction of 0.65 and 0.83 respectively. When HSGsuggests the presence of tubal obstruction this will beconfirmed by laparoscopy in only 38% of women.Thus, HSG isnot a reliable indicator of tubal occlusion. However, when HSGsuggests that the tubes are patent, this will be confirmed atlaparoscopy in 94% of women. Thus HSG is a reliableindicator of tubal patency.

    • Diagnosi di Fattore tubarico di Sterilita’ Quale metodica?A postal survey was conducted among gynecologistsand radiologists to find out the current practice inthe UK regarding the methods employed to assesstubal patency. In the responses from radiologists, aHSG was the investigation of choice for both lowrisk (61%) and high risk women (50%). In theresponses from gynecologists, in low risk themajority perfomred a HSG (58%) or HyCoSo(15ì4%), whereas in high risk most (84%) performeda laparoscopy Vvjayanthi S, Hum Fertil (Camb) 2004
    • Quando?
    • Quando? ? ? The specific definition of infertility is inability of a couple to conceive after 1 year of sexual intercourse without contraception. The initial diagnostic test for infertility should include a midulteal progesteron assay, a semen analysis and a test for tubal patency such as HSG. The ESHRE Capri Workshop Group: “Optimal use of infertility diagnostic tests and treatments”. Human Reproduction 15:723, 2000
    • Diagnosi di Fattore tubarico di Sterilita’ E’ necessaria la laparoscopia dopo HSG normale?When tubal patency has been demonstrated by HSG,laparoscopy is traditionally suggested as a mandatorystep to preclude the existence of peritubal adhesions andendometriosis. In women without a hystory suggestive oftubal disease and a normal HSG, we demonstrate thatthe probability of clinicallly relevant disease is very lowand laparosocpy does not seem to be justified or cost-effective. In these cases surgery has not been proven toimprove fecundity, and we suggest 3-6 cycles ofCOH/IUI, and if unsuccesful, IVF Fatum M, Hum Reprod 2002
    • STERILITA’ DA FATTORE TUBARICO La sterilità da fattore tubo-peritoneale (aderenze pelviche, occlusioni tubariche prossimali e distali, endometriosi) rappresenta il fattore eziologico nel 40% dei casi di sterilità femminile

    • “This finding suggest that the value of laparoscopic adhesiolysisdoes not lie in the adhesiolysis itself.Adhesions do not cause pain unless they are causing anobstruction.Diagnostic laparoscopy could be of benefit to patients byrevealing other causes of their pain.We recommend that clinicians consider abandoning laparoscopicadhesiolysis as a treatment” DJ Swank, Lancet 2003

    • Come prevenire le aderenze incorso di chirurgia annessiale?
    • In letteratura è disponibile un’ampiaserie di dati, sia sperimentali che clinici,ma a tutt’oggi non esiste un metodouniversalmente accettato per laprevenzione delle aderenze
    • For laparoscopy, the perceived postoperative de novo adhesion formation rate was 0%-25%, whereas the adhesion reformation rate was 26%-75%; for laparotomy, the rates were 26%- 75% and >75%, respectively.Sixty-five percent of the respondents were using at least onemethod for postoperative adhesion prevention duringlaparoscopy, and 68% during laparotomy.The most frequentlyused method during laparoscopy was Ringers lactate (77% ofthe respondents), followed by ferric hyaluronate gel (46% ofthe respondents), and 4% icodextrin (39% of respondents).During laparotomy, the most frequently used methods wereRingers lactate (28%), normal saline (20%), and 4%icodextrin (20%). Antibiotic prophylaxis was used by 87.5% ofrespondents. Muzii, JAAGL 2004
    • Crystalloid Solutions• Continuous irrigation is positive because: – prevents fibrin deposition and wash away fibrinous exudates – it can keep the tissues moist• Intraperitoneal solutions at the end of surgery: – active on all peritoneal surfaces, possibly preventing de novo – easy to use, reduced costs• However, doubts on the efficacy: – rate of absorption is 35 ml/hour – 300 ml are absorbed in 8.5 hours – the process of peritoneal healing and adhesion formation takes place during the first 5-7 days

    • AGENTI DI BARRIERA• 15 RCTs• LPTM = 9, LPS = 6• Aderenze pelviche 6, Miomectomia 5, Chirurgiaovarica 4, Endometriosi 2, Indicazioni varie 1• 13 studi: Interceed vs. controllo, 2 studi: Interceed vs.Gore-Tex, 1 studio: Gore-Tex vs. controllo, 1 studio:Seprafilm vs. controllo• In nessuno studio sono state valutate Gravidanze eRiduzione del dolore
    • AGENTI DI BARRIERA• L’uso dell’Interceed e’ associato ad una minore incidenzadi formazione di aderenze (sia ri-formazione cheformazione de novo) dopo chirugia laparoscopica elaparotomica• Il Gore-Tex e’ piu’ efficace di nessun trattamento o diInterceed• Evidenze limitate sull’efficacia del Seprafilm per laprevenzione di aderenze dopo miomectomia• Interceed efficace nel ridurre le aderenze, ma datiinsufficienti per raccomandarne l’uso per migliorare lepercentuali di gravidanza
    • AGENTI LIQUIDI / FLUIDI• Nessuno degli agenti liquidi o fluidi studiati hadeterminato un aumento delle percentuali di gravidanza.• Alcune evidenze sull’efficacia degli steroidi nel ridurrel’incidenza e la severita’ della formazione di aderenze.Destrano inefficace.• L’uso di routine di questi agenti non puo’ essereraccomandato sulla base delle evidenze disponibili.• L’evidenza sugli steroidi e’ ben lontana dall’essereperfetta, ma suggerisce l’efficacia. Dovrebbero esserecondotti studi addizionali.

    • CONCLUSIONI - AderenzeNonostante l’enorme mole di dati presenti inletteratura, non esiste oggi un approcciouniversalmente accettato. L’Interceed è ilmetodo sul quale oggi esistono più studi. Nuovimetodi di barriera in studio. L’approcciolaparoscopico, probabilmente, determina unariduzione delle aderenze “de novo”. Lariformazione delle aderenze dopo adesiolisisembra invece essere la norma più chel’eccezione, anche in laparoscopia.
    • CONCLUSIONILa corretta indicazione all’intervento chirurgicoè probabilmente il mezzo più efficace perprevenire le aderenze postoperatorie.L’accurata selezione delle pazienti e il rispettodelle indicazioni sono i punti-chiave per ottenerei migliori risultati in chirurgia laparoscopica delfattore tubo-peritoneale di sterilitàL’utilizzo di tecniche chirurgiche nel rispetto deitessuti è l’altro punto fondamentale.
