Objective Knowledge of retroperitoneal anatomy is particularly important in order to facilitate the surgical procedure and reduce the number of complications. The objective of this video is to demonstrate pelvic neuroanatomical structures and their relationships in the pelvic side wall and the presacral space in a laparoscopic cadaveric dissection. Design Case report (anatomical study). Setting Medical Training Center (AdventHealth Nicholson Center, Orlando, FL, USA). The authors have no conflicts of interest to declare. Interventions The dissection started by the mobilization of the iliac vessels from the pelvic sidewall in order to identify the obturator nerve. The peritoneum of the ovarian fossa was opened, and the ureter was dissected up to the level of the uterine artery. The hypogastric nerve was identified. The close relationship between the ovarian fossa and the obturator nerve could be demonstrated. The deep dissection of the obturator fossa allowed for the identification of the lumbosacral trunk, S1, sciatic nerve, S2, S3, S4, and splanchnic nerves. Then, the ischial spine and the sacrospinous ligament were identified. The pudendal nerve and vessels could be observed passing below the sacrospinous ligament, entering the pudendal canal (Alcock's canal). The presacral space was dissected and the hypogastric fascia was opened. S1 to S4 were identified coming from the sacral foramens. The laparoscopic dissection using the cadaveric model allowed for the development of the entire retroperitoneal anatomy, focusing on the dissection of the pelvic innervation. Anatomical relationships among ureter, hypogastric nerve, uterosacral ligament, splanchnic nerves, inferior hypogastric plexus, and the organs (bowel, vagina, uterus, and bladder) could be demonstrated. Conclusion A laparoscopic cadaveric dissection can be used as a resource to demonstrate and educate surgeons about neurological retroperitoneal structures and their relationships.

OBJETIVO: comparar a efetividade da sonda e Foley com o uso de misoprostol vaginal para o preparo cervical e indução do parto. MÉTODOS: ensaio clínico randomizado, não cego, realizado entre Janeiro de 2006 a Janeiro de 2008. Foram incluídas 160 gestantes com indicação de indução do parto, divididas em dois grupos: 80 para uso da sonda de Foley e 80 para misoprostol vaginal. Os critérios de inclusão foram: idade gestacional a partir de 37 semanas, feto único, vivo, cefálico e índice de Bishop igual ou menor que 4. Foram excluídas pacientes com cicatriz uterina, ruptura das membranas, peso fetal estimado maior que 4000 g, placenta prévia, corioamnionite e condições que impunham o término imediato da gestação. Os testes estatísticos utilizados foram Mann-Whitney, χ2 de Pearson ou exato de Fischer, sendo considerado significativo se menor que 0,005. RESULTADOS: o misoprostol desencadeou mais vezes o parto de forma espontânea (50,0 versus 15,0% para Foley p

To compare the effectiveness of the Foley balloon with vaginal misoprostol for cervical ripening and labor induction.Randomized clinical trial, not blind, conducted from January 2006 to January 2008. A total of 160 pregnant women with indication for induction of labor were included and divided into two groups, 80 for Foley and 80 for vaginal misoprostol. Inclusion criteria were: gestational age of 37 weeks or more, a live single fetus with cephalic presentation and a Bishop score of four or less. We excluded patients with a uterine scar, ruptured membranes, estimated fetal weight greater than 4000 g, placenta previa, chorioamnionitis and conditions that imposed the immediate termination of pregnancy. Statistical tests employed were Mann-Whitney, χ² test or Fisher's exact test, and p value was significant if less than 0.005.Misoprostol triggered more frequently spontaneous delivery (50.0 versus 15.0% for Foley, p0.001) and required less use of oxytocin (41.2 versus 76.2%), and this group presented more tachysystole (21.2 versus 5.0%). The Foley catheter caused more discomfort to the patient (28.7 versus 1.2%). There were no differences in the time required for development of the Bishop score (20.69 versus 21.36 hours), for triggering delivery (36.42 versus 29.57 hours) or in rates of cesarean delivery (51.2 versus 42.5%). There were no significant differences in perinatal performance, with similar rates of abnormal cardiotocography (20.0 versus 21.2%), presence of meconium (13.7 versus 17.5%) and need for neonatal intensive care unit (3.7 versus 6.2%).The use of the Foley catheter was as effective as misoprostol for cervical ripening, but less effective in triggering spontaneous labor. Our results support the recommendation of its use for cervical ripening, especially in patients with cesarean scar.

Uterine leiomyomas are characterized as a benign disease and are observed in 2 to 3% of all normal pregnancies. Out of these, about 10% may present complications during pregnancy. We present a case of a pregnant patient sought emergency obstetric care at the 17th week, complaining of severe pain, presenting with painful abdominal palpation and sudden positive decompression. Ultrasonography revealed a myoma nodule measuring 9.1 x 7.7 cm; the patient was hospitalized and medicated, being also submitted to laparotomy and myomectomy due to worsening of her condition. Prenatal care revealed no further abnormalities, with resolution of gestation at 39 weeks. The newborn weighed 3,315 g, with Apgar scores of 9 and 10. In such cases, clinical treatment should always be attempted and surgery should be considered only in selected cases, mainly in the impossibility of conservative treatment or when the patient's clinical features require immediate intervention. In this case, myomectomy was effective against maternal-fetal obstetric complications.

CONTEXT AND OBJECTIVE: The incidence of scar endometrioma ranges from 0.03 to 3.5%. Certain factors relating to knowledge of the clinical history of the disease make correct diagnosis and treatment difficult. The aim here was to identify the clinical pattern of the disease and show surgical results. The literature on this topic was reviewed. DESIGN AND SETTING: Retrospective descriptive study at Hospital Municipal Maternidade - Escola Dr. Mário de Moraes Altenfelder Silva. METHODS: Data from the medical records of patients with preoperative diagnoses of scar endometrioma who underwent operations between 2001 and 2007 were surveyed and reviewed. The postoperative diagnosis came from histopathological analysis. The main information surveyed was age, obstetric antecedents, symptoms, tumor location, size and palpation, duration of complaint, diagnosis and treatment. All patients underwent tumor excision with a safety margin. RESULTS: There were 33 patients, of mean age 30.1 ± 5.0 years (range: 18-41 years). The total incidence was 0.11%: 0.29% in cesarean sections and 0.01% in vaginal deliveries. Twenty-nine tumors (87.9%) were located in cesarean scars, two (6.0%) in episiotomy scars and two (6.0%) in the umbilical region. The main symptom was localized cyclical pain (66.7%), of mean duration 30.5 months (± 23). Surgical treatment was successful in all cases. CONCLUSION: This is an uncommon disease. The most important diagnostic characteristic is coincidence of painful symptoms with menstruation. Patients undergoing cesarean section are at greatest risk: relative risk of 27.37 (P < 0.01). The surgical treatment of choice is excision of the endometrioma with a safety margin. CONTEXTO E OBJETIVO: A incidência de endometrioma de cicatriz varia de 0,03 a 3,5%. Alguns fatores relacionados ao conhecimento da história clínica da doença dificultam o diagnóstico e o tratamento corretos. O objetivo é traçar o padrão clínico da doença e avaliar resultados cirúrgicos. Foi revisada a literatura sobre o assunto. TIPO DE ESTUDO E LOCAL: Estudo descritivo e retrospectivo realizado no Hospital Municipal Maternidade - Escola Dr. Mário de Moraes Altenfelder Silva. MÉTODOS: Foi realizado levantamento e revisão de dados dos prontuários médicos das pacientes com diagnóstico pré-operatório de endometrioma de cicatriz, operadas entre 2001 e 2007. O diagnóstico pós-operatório foi feito por exame histopatológico. As principais informações levantadas foram: idade, antecedentes obstétricos, sintomatologia, localização, tamanho e palpação do tumor, duração da queixa, diagnóstico, tratamento. Todas as pacientes foram submetidas a exerese da massa tumoral com margem de segurança. RESULTADOS: Foram encontrados 33 pacientes com média de idade 30,1 (± 5,0), variando de 18 a 41 anos. A incidência total foi de 0,11%, nas cesarianas foi de 0,29% e nos partos vaginais, 0,01%. Localização do tumor: 29 casos em cicatriz de cesária (87,9%), dois em região umbilical (6,0%) e dois em cicatriz de episiotomia (6,0%). A principal sintomatologia foi dor cíclica localizada (66,7%), com duração média de 30,5 meses (± 23). O tratamento cirúrgico foi realizado com sucesso em todas as pacientes. CONCLUSÃO: Trata-se de uma doença incomum. O dado de maior importância diagnóstica foi: coincidência da sintomatologia dolorosa com a menstruação. Pacientes submetidas a cesariana têm maior risco (risco relativo = 27,37 e P < 0,01). O tratamento cirúrgico de escolha é exerese do endometrioma com margem de segurança.

OBJETIVO: apresentar uma técnica cirúrgica para pacientes submetidas ao parto cesáreo e que evoluem com hemorragia refratária ao uso de medicamentos. MÉTODOS: o critério de seleção das pacientes era falha do tratamento farmacológico no controle da hemorragia pós-parto e o desejo da paciente em preservar o útero. As pacientes foram submetidas ao parto cesáreo e evoluíram com hemorragia pós-parto imediata refratária ao uso de ocitocina, ergometrina e misoprostol. Aplicamos a técnica de sutura descrita por B-Lynch sem modificações. Com fio cromado catgut-2 ou poliglactina-1, transfixamos o útero em seis pontos, conforme padronização. Após compressão manual do útero realizada pelo assistente, o fio é tracionado pelas suas extremidades pelo cirurgião e é aplicado um nó duplo seguido de dois nós simples, para em seguida realizar-se a histerorrafia. RESULTADOS: utilizamos o fio cromado catgut-2 agulhado em três casos e poliglactina-1 agulhado em um. Nos quatro casos houve parada imediata do sangramento vaginal após aplicação da sutura. Não houve qualquer complicação durante a realização do procedimento e nem no puerpério imediato e tardio das quatro pacientes. CONCLUSÕES: esta técnica representa uma alternativa cirúrgica para o manejo da hemorragia pós-parto. Com sua aplicação relativamente fácil, rápida e segura, pode representar uma redução da morbimortalidade materna em nosso país. PURPOSE: to present a surgical technique for patients submitted to caesarean section, which evolves to medicine refractory hemorrhage. METHODS: a case report study, of which the including criteria were failure in the pharmacological treatment to control post-partum hemorrhage, and the patients' request to preserve their uterus. Four patients submitted to caesarean section which evolved to immediate post-partum hemorrhage, refractory to the use of ocytocin, ergometrine and misoprostol, were treated with the suture technique described by B-Lynch, without modification. The uterus was transfixed in six points according to the standard procedure, with chrome catgut-2 or polyglactine-1thread. After the assistant's manual compression of the uterus, the thread was pulled by its extremities by the surgeon, and a double knot followed by two simple knots were applied before performing the hysterorraphy. RESULTS: needled chrome catgut-2 thread was used in three cases and needled poluglactine-1 in one case. In the four cases there was immediate discontinuity of the vaginal bleeding, after the suture. The four patients did not present any complication during the procedure or along the immediate and late puerperal period. CONCLUSION: this technique represents a surgical alternative to deal with post-partum hemorrhage and may represent a reduction in the maternal morbidity and mortality in our country.
