RESUMO
OBJECTIVE: To compare the prevalence of adjacent organ injury in placenta accreta spectrum disorder (PAS) between the posterior colpotomy approach and conventional peripartum hysterectomy. METHODS: This retrospective study analyzed the data of pregnant women diagnosed with PAS who underwent peripartum hysterectomy at Songklanagarind Hospital between January 2006 and December 2021. The patients were divided into two groups: posterior colpotomy and conventional approaches. The characteristics and surgical and obstetric outcomes were compared. Univariate and multivariate logistic regression was used to identify factors and risk of organ injury. RESULTS: Among 174 patients, 64 underwent conventional peripartum hysterectomy, and 110 underwent the posterior colpotomy approach. The overall incidence of adjacent organ injury was 17.82%. Organ injury prevalence was lower in the posterior colpotomy group (10%) than in the conventional group (31.25%), with no difference in operative time. Multivariate analysis showed that posterior colpotomy reduced adjacent organ injury (odds ratio [OR] 0.18, 95% confidence interval [CI] 0.06-0.54, P = 0.002). Placenta percreta was associated with increased injury risk (OR 6.83, 95% CI 2.53-18.44, P < 0.002). Subgroup analysis showed that the posterior approach reduced bladder injury in placenta increta (OR 0.14, 95% CI 0.04-0.57, P = 0.003) and percreta (OR 0.19, 95% CI 0.05-0.77, P = 0.017). CONCLUSION: Compared with conventional peripartum hysterectomy, the posterior colpotomy approach in patients with PAS reduced the risk of adjacent organ injury, particularly for placenta increta and percreta. This technique should be considered in PAS cases, but further investigations with a prospective study design are needed.
RESUMO
OBJECTIVE: The aim of the study was to evaluate the outcomes of placenta accreta spectrum (PAS) disorder managed by a multidisciplinary care team (MCT) compared with a conventional care team (CCT) in a PAS referral center in Thailand. METHODS: This retrospective single-center cohort study analyzed PAS management outcomes in the PSU PAS Center between January 2010 and December 2022. The incidence of hemorrhage ≥3500 mL and the composite maternal and neonatal outcomes of PAS were compared before and after the introduction of an MCT in 2016. RESULTS: Of 227 PAS cases, 219 (96.5%) had pathological confirmation. There were 52 (22.9%) cases of placenta accreta, 119 (52.4%) cases of placenta increta, and 56 (24.7%) cases of placenta percreta. The incidence of estimated blood loss (EBL) ≥3500 mL decreased from 61.8% to 34.3% (P < 0.001) after the establishment of the MCT. The median EBL decreased from 4000 (IQR: 2600,7250) mL to 2250 (1300, 4750) mL (P < 0.001). EBL reduction was statistically significant in the accreta and increta groups (P < 0.001). Red blood cell transfusions decreased from five (3, 9) to two (1, 6) units (P < 0.001) per patient. The length of maternal hospital stays and ICU admissions were statistically shorter when PAS was managed by an MCT (P < 0.001). The length of newborn hospital and ICU stays decreased significantly (P < 0.001). CONCLUSION: The incidence of massive postpartum hemorrhage and a composite of maternal and neonatal morbidities in pregnant women with PAS disorder improved significantly after the establishment of an MCT to manage PAS in a middle-income country setting.

OBJECTIVE: To identify the impact of time interval between surgery and initial adjuvant radiotherapy on oncologic outcomes in early-stage endometrial cancer. METHODS: This retrospective cohort study included patients with stage I/II endometrial cancer who underwent surgical staging and adjuvant therapy at Songklanagarind Hospital from January 1, 2007, to December 31, 2017. Patients were categorized into two groups: TI <6 weeks and TI ≥6 weeks. The effects of TI and clinicopathological factors on recurrence-free survival (RFS) and overall survival (OS) were analyzed using Cox proportional-hazards regression. RESULTS: In total, 177 patients were enrolled, with 52% receiving adjuvant radiotherapy at <6 weeks (overall median TI 5.7 weeks). The recurrence and death rates were 13% and 10.2%, respectively. The median follow-up time was 46.6 months. The overall 3-year RFS and OS rates were 88.2% and 85.2%, respectively. The TI significantly affected the 3-year RFS (94.4% vs 81.2%; P = 0.008) and 3-year OS (95.5% vs 83.2%; P = 0.012) in patients with TI <6 and ≥6 weeks, respectively. In multivariate analysis, the depth of myometrial invasion (MI), presence of lymphovascular space invasion, and TI were independent prognostic factors for both RFS and OS. Delaying the TI (≥6 weeks) was significantly associated with a worse RFS (hazard ratio [HR] 3.70; 95% confidence interval [CI]: 1.34-10.22; P = 0.012) and an inferior OS (HR 3.80; 95% CI: 1.23-11.69; P = 0.02). CONCLUSION: A delay in the TI between surgery and the initiation of adjuvant radiotherapy of ≥6 weeks negatively affected the oncologic outcomes in early-stage endometrial cancer.
