RESUMEN
BACKGROUND: Intravascular leiomyomatosis is a rare benign lesion with malignant potential. The cases are sporadic. Most patients have no clinical symptoms, and the preoperative diagnostic rate is low. Case 1 was misdiagnosed, passively managed during operation, recurred quickly, and underwent a secondary operation. We learned lessons from case 1 and treated the case 2 patient differently. The case 2 patient had a good prognosis. We hope the report will be helpful to other gynecologists. CASE SUMMARY: Case 1: a 49-year-old woman complained of dysmenorrhea. Traditional ultrasound showed adenomyosis and a solid mass 6 * 3 cm in the right appendix. After routine examination, the patient underwent transabdominal total hysterectomy + bilateral salpingectomy + IVL tumor resection, with both ovaries kept. No medication was used after operation. Routine ultrasound was performed every 3 months. The disease recurred, and the patient underwent a secondary surgery 9 months after the first time. So far, 25 months after the secondary surgery, there is no sign of recurrence. Case 2: a 41-year-old woman underwent a routine body examination, where a left adnexal mass 7 cm was found. The patient underwent contrast-enhanced ultrasonography and was diagnosed and prepared well preoperatively. The patient underwent transabdominal total hysterectomy + bilateral salpingectomy + IVL tumor resection. GnRH-a drugs were used after operation for 3 cycle. Now, there is no sign of recurrence after operation for 23 months. CONCLUSION: The incidence rate of IVL is low, and there are no typical clinical symptoms. It is easy to be ignored by gynecologists. Contrast-enhanced ultrasound is helpful to diagnose preoperatively and reduce misdiagnosis. Good preparation, full exploration of the pelvic and abdominal vessels, removal of lesions completely as much as possible, and anti-estrogen therapy after operation can reduce the recurrence of disease.
RESUMEN
Background: The association between a diverse array of environmental risk factors and the risk of endometriosis is contradictory. Objective: To summarize the evidence of associations between environmental risk factors and the risk of endometriosis. Methods: Databases such as PubMed, EMBASE, Web of Science, and ClinicalTrial.gov were systematically searched in June 2020. Meta-analyses of observational studies investigated any environmental exposure (non-genetic) and endometriosis risk. For each article, we estimated the summary effect size, 95% CIs, and the 95% prediction interval (PI). We also estimated the between-study heterogeneity expressed by I 2, evidence for small-study effects, and evidence of excess significance bias. Results: About 12 eligible articles (featuring 143,422 cases and 5,112,967 participants) yielded data on 40 unique environmental risk factors, including life styles (n = 16), reproductive factors (n = 3), early life factors (n = 4), and a range of other risk factors [e.g., phthalate metabolites, endocrine-disrupting chemicals, and body mass index (BMI)]. About 25 of these 40 associations (62.5%) were statistically significant (p < 0.05) under random-effects models. Evidence for an association was indicated for alcohol intake [relative risk (RR): 1.25; 95% CI: 1.11-1.41] and the exposure to endocrine disruptor chemicals (EDCs) (RR: 1.41; 95% CI: 1.23-1.60) while 15 associations presented only weak evidence. Conclusions: Our analyses showed that alcohol intake and exposure to endocrine-disrupting chemicals may be potential risk factors for endometriosis and supported by suggestive epidemiological evidence. However, it was evident that there was substantial heterogeneity and/or bias between the different studies featured in various meta-analyses included in this review; therefore, the outcomes of our analysis should be interpreted cautiously.
RESUMEN
BACKGROUND: The traditional definition of late postpartum hemorrhage is a massive uterine hemorrhage from 24 h after delivery to the puerperal period. Here, we report a case of late postpartum hemorrhage that occurred 3 mo after cesarean section and endangered the patient's life. The cause of the case we are reporting was poor incision healing. By reporting this case, we hope to make doctors aware that late postpartum hemorrhage due to poor incision healing may happen as late as 3 mo after cesarean section. CASE SUMMARY: A 31-year-old woman complained of acute, severe vaginal bleeding for 1 h; the patient had a history of cesarean section 3 mo prior. After receiving anti-inflammatory treatment, fluid supplementation, blood transfusion, oxytocin administration, and hemostatic treatment, the vaginal bleeding ceased, and the patient's clinical status improved. Unfortunately, she experienced recurrent massive vaginal bleeding, and uterine contractile agents did not decrease the persistent bleeding. To save the patient's life, she was admitted for emergency laparotomy. At exploratory laparotomy, dehiscence and necrosis of the previous cesarean section scar were noted; the dehiscence penetrated through the entire thickness of the uterine muscle wall and extended to the left uterine artery. Ultimately, we performed a total hysterectomy. CONCLUSION: Late postpartum hemorrhage due to poor incision healing after cesarean section may occur in the 3 mo after cesarean section or even later. Therefore, obstetricians-gynecologists should monitor for this potential complication in all patients post-cesarean section. Such hemorrhages can be severe enough to endanger the patient's life.
