P-315 To study the efficacy of Transvaginal ultrasound-guided Embryo Transfer over Transabdominal ultrasound-guided Embryo Transfer in transfers with poor visibility due to obesity or marked retroversion

Abstract Study question Why is Transvaginal guided embryo transfer,understudied and underutilised in difficult cases of transfers with compromised visibility uterine canal Transabdominal ultrasound ? Summary answer In patients poor using TAUS due Obesity, retroveted uterus,PID,pelvic adhesions, endometriosis, TVUS-ET gives significantly higher clinical Pregnancy rates. What known already TAUS-ET most popular method Embryo transfer worldwide. Despite the benefits , this procedure also presents some important drawbacks. Firstly, TAUS-guided ET requires an assistant to operate transducer while physician performs procedure. Moreover, patient needs fill her urinary bladder enable visualization canal, which causes discomfort sometimes cramping during ET, turn can negatively impact implantation rates.TVUS main technique used all other gynecological investigations. Because high frequency close proximity target area, TVUS transducers provide better resolution uterocervical angle improved overall image quality. design, size, duration This retrospective study was conducted compare efficacy TVUS-guided conventional transfers, who underwent treatment at Triveni IVF, Darbhanga, India between November 2020 December 2022. It based on data extracted from records women Nov 2021.Data matching number Dec 2021 2022 were for comparison. Participants/materials, setting, methods All ICSI FET transfers. Inclusion criteria: (1) included 25–35 years age visualisation TAUS-Mock previous cycle (2) BMI ≥ 30; (3) Retroverted uterus any underlying pathology 4)All pts had good ovarian reserve; (4) unexplained infertility >3 years. Exclusion severe male factor infertility, intrauterine endometrioma or PCOS (5) multiple failure (>3 trials). Main results role chance Total 123 cycles,61 by (Group 1) 62 2) included. Our showed Clinical rate group as compared group, (43.3% vs. 36.1 % p = 0.0045). VAS (visual analog scale) pain less comparison (17% vs 64% 0.0001), abdominal (11% 69 0.0001). CPR it has organs allowing proper catheter tip especially obesity marked retroversion.TVUS superior because easily analyze cause endocervical crypts, anteverted uterus, cervical tortuosity. Another advantage requiring emptied contrast TAUS. Full both time consuming cramps leading increased anxiety.As regards cramps, there extremely statistical significance two groups our study. Limitations, reasons caution wide benefits,TVUS-ET not been widely adopted, account difficulty manipulating vaginal simultaneously very constricted area.Other comfortable approaches that may assist physicians such inner be pushed embryologist holds TVS-probe outer place. Wider implications findings The suggested studied sample. presented deserves consideration wider use since offer visualization, excellent comfort procedure, only one operator.
