PURPOSE: To verify the predictors of intravasation rate during hysteroscopy. METHODS: Prospective observational study (Canadian Task Force classification II-1). All cases (n=200 women; 22 to 86 years old) were treated in an operating room setting. Considering respective bag overfill to calculate water balance, we tested two multiple linear regression models: one for total intravasation (mL) and the other for absorption rate (mL.min -1). The predictors tested (independent variables) were energy (mono/bipolar), tube patency (with/without tubal ligation), hysterometry (cm), age≤50 years, body surface area (m 2 ), surgical complexity (with/without myomectomy) and duration (min). RESULTS: Mean intravasation was significantly higher when myomectomy was performed (442±616 versus 223±332 mL; p<0.01). In the proposed multiple linear regression models for total intravasation (adjusted R 2 =0.44; p<0.01), the only significant predictors were myomectomy and duration (p<0.01).In the proposed model for intravasation rate (R 2 =0.39; p<0.01), only myomectomy and hysterometry were significant predictors (p=0.02 and p<0.01, respectively). CONCLUSIONS: Not only myomectomy but also hysterometry were significant predictors of intravasation rate during operative hysteroscopy. ResumoOBJETIVO: Testar preditores do ritmo de intravasamento durante histeroscopia cirúrgica. MÉTODOS: Estudo prospectivo observacional (classificação: Canadian Task Force II-1) incluindo casos conduzidos em centro cirúrgico (n=200 mulheres; 22 a 86 anos de idade). Considerando os erros de aferição nas embalagens de solução de irrigação para calcular o balanço hídrico, nós testamos dois modelos de regressão linear múltipla: um para intravasamento total (mL) e outro para ritmo de intravasamento (mL.min -1 ). Os preditores testados (variáveis independentes) foram energia (mono/ bipolar), permeabilidade tubária (com/sem ligadura tubária), histerometria (cm), status ovariano (idade≤50 anos), área de superfície corporal (m 2 ), complexidade de cirurgia (com/sem miomectomia) e tempo de ressecção (min). RESULTADOS: O intravasamento médio foi significativamente maior quando miomectomia foi realizada (442±616 versus 223±332 mL, p<0,01). No modelo proposto para intravasamento total (R 2 ajustado=0,44; p<0,01), os únicos preditores significativos foram miomectomia e tempo de duração (p<0,01). No modelo proposto para a taxa de intravasamento (R 2 =0,39; p<0,01), somente miomectomia e histerometria foram preditores significativos (p=0,02 e p<0,01, respectivamente). CONCLUSÕES: Não só a miomectomia mas também a histerometria são preditores significativo da taxa de intravasamento durante histeroscopia cirúrgica.
Introduction. Early in the 2020 Coronavirus pandemic stay-at-home guidelines, there were public health orders that elective surgeries be deferred to prioritize hospital beds for critically ill COVID-19 patients. Besides, several reasons led to the postponement of consultations, diagnostic tests, and elective therapeutic procedures. As a result, some women with endometriosis faced chronification of their pain and decreased prospects for pregnancy. The aim of this study was to describe individual responses to minimally invasive complete excision of endometriosis through 40 days of follow-up of women whose endometriosis was considered severe enough to proceed with surgery during the fourth, fifth, and sixth months of constraints imposed by the pandemic. Preventive strategies and safety measures employed to protect patients and staff from acquiring or transmitting Coronavirus infection are presented. Case Presentation. This case series report enrolled 11 consecutive Brazilian women (ages 22 to 47 y) who underwent minimally invasive surgical treatment of endometriosis between June 26 and August 17, 2020. Cases of endometriosis requiring more urgent surgery were promptly identified and considered individually. The strict safety measures were well accepted by patients. No women developed any flu-like or COVID-19-related symptoms (cough, dyspnea, fever, or anosmia) in the 40 days of postoperative follow-up. One of the most praised measures reported by patients was the routine testing of the patient, the person who would accompany her in the hospital, and all medical staff and employees. Discussion. It is feasible to safely perform elective endometriosis surgery in selected cases during a pandemic.
