Opinions concerning pre-implantation genetic diagnosis and sex selection among gynecologist-obstetricians in Brazil.

OBJECTIVE: The aim of this study was to assess a sample of obstetrician-gynecologists on their technical knowledge of PGD as well as their views of PGD and sex selection (SS). STUDY DESIGN: Cross-sectional observational study, carried out during a Congress on Gynecology and Obstetrics. A self-report questionnaire was offered to all professionals registered to attend the Congress and answers of 723 physicians were analyzed. RESULTS: Of the participants, 436 (60.3%) were female and 287 (39.7%) were male; 517 (71.5%) had children. Regarding knowledge of PGD techniques, 63.2% had heard something about PGD and/or preconception SS. Concerning SS, physicians believed that SS is always the couple's choice (36.4%), should be the couple's choice only in specific situations (42.6%), or did not agree that SS should be a couple's choice (17.4%). A majority of the respondents were in favor of PGD and believed that pre-embryos with 6-8 cells are human life in potency. CONCLUSIONS: In spite of a small percentage of gynecologists-obstetricians in Brazil had knowledge of PGD techniques, many of them recognized it to be a method to prevent genetic diseases and agreed with its use. The SS appears to be highly accepted for use in specific situations.

Reservatorio ileal pelvico. Detalhes de tecnica operatoria e avaliaçao das complicaçoes / Pelvic ileal pouch - operative techniques details and evaluation of complications

Colectomia total, proctomucosectomia e reservatorio ileal em forma de "S", anastomosado ao canal anal, foram empregados como tratamentocirurgico da retocolite ulcerativa ou da polipose familiar em 14 pacientes. A incidencia de complicaçoes no pos-operatorio precoce e tardio foi analisada em pacientes do Grupo I (reservatorio grande, ramo ileal eferente longo e coto retal grande) e do Grupo II (reservatorio pequeno, ramo ileal eferente curto e coto retal pequeno). Sepse pelvica, estenose ileo-anal e ileite do reservatorio foram ascomplicaçoes mais frequentes. A sepse pelvica ocorreu em cinco pacientes do Grupo I e foi ausente no Grupo II; a estenose ileo-anal foi observada em tres pacientesdo Grupo I e em um paciente do Grupo II; a ileite do reservatorio foi vista em dois pacientes do Grupo II. Embora a necessidade de reoperaçoes e a mortalidade nao tenham sido relacionadas a tecnica operatoria, tres casos - os quais ou foram reoperados ou morreram (dois pacientes) - pertenciam ao Grupo I. Em conclusao, uma menor incidencia de complicaçoes pos-operatorias e esperada quando o reservatorio e construido em menor tamanho, com ramo ileal eferente mais curto e coto retal menor
