Comparative study of the prevalence of organ injury in placenta accreta spectrum disorder between posterior colpotomy and conventional peripartum hysterectomies at a single referral center in southern Thailand.

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.

Successful multidisciplinary team management of placenta accreta spectrum disorder: A referral center model in a middle-income country.

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.

Effect of time interval between surgery and the initiation of adjuvant therapy on the oncologic outcomes of early-stage endometrial cancer.

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.

Comparative outcomes between transvaginal endoscopic hysterectomy and total laparoscopic hysterectomy in patients with benign uterine disease: A single-center, retrospective, cohort, interrupted time-series study.

OBJECTIVES: To compare the surgical outcomes of total laparoscopic hysterectomy (TLH) and transvaginal endoscopic hysterectomy (TVEH) for benign uterine diseases. METHODS: This retrospective, cohort, interrupted time-series study included patients who underwent TLH between January 2013 and September 2016 and TVEH between October 2016 and June 2020. Median difference regression was used to compare the hospital length of stay (LOS) and operative time between the groups. Risk difference regression was used to analyze the proportion of patients who developed postoperative fever or vaginal stump infection. RESULTS: Of the total 171 patients enrolled, 101 and 70 underwent TVEH and TLH, respectively. The mean ages of patients in the TVEH and TLH groups were 46.49 and 46.17 years, respectively. No conversion was observed. Ureteric injury occurred in one patient in the TVEH group, whereas there was no organ injury in any of the patients in the TLH group. Compared with those in the TLH group, patients in the TVEH group had a significantly shorter median operative time, shorter hospital LOS, lower morphine use, and lower postoperative febrile morbidity rates. However, no significant difference was observed in the rate of vaginal stump infection between the groups. CONCLUSION: Given the shorter operative time, shorter hospital LOS, less febrile morbidity, and lower morphine use in patients with TVEH than in those with TLH, TVEH should be considered as an alternative hysterectomy procedure for benign uterine diseases.

Appendiceal tumors in patients undergoing primary surgery for mucinous ovarian tumors in a tertiary hospital, in Southern Thailand.

OBJECTIVE: To evaluate the prevalence of appendiceal tumors in patients diagnosed with mucinous ovarian tumors and to determine factors associated with coexisting appendiceal tumors. MATERIALS AND METHODS: Retrospective review of all patients who were diagnosed with mucinous ovarian tumors and underwent an appendectomy during surgery between January 2002 and June 2017 was performed. Univariate and multivariate logistic regression analyses were used to identify risk factors for coexisting appendiceal tumors. RESULTS: A total of 303 patients with mucinous ovarian tumors who underwent appendectomy were identified, including 77 (25.4%) mucinous cystadenoma and 226 (74.6%) mucinous borderline tumor or carcinoma. Twenty-one (6.9%) had coexisting appendiceal tumors including 8 that were primary appendiceal mucinous adenocarcinomas, 6 low-grade appendiceal mucinous neoplasms, 6 secondary appendiceal metastasis from the ovary, and one hyperplastic polyp. None of mucinous cystadenoma had coexisting appendiceal tumors. Multivariate analysis revealed advanced age ≥50 years, previous rupture of ovarian tumors, abdominal extension of tumors, and grossly abnormal appendix were independent factors for coexisting appendiceal tumors. CONCLUSION: Prevalence of coexisting appendiceal tumors in mucinous ovarian tumors was not uncommon. The risk factors were grossly abnormal appendix, abdominal extension of tumor, previous rupture of ovarian tumors, and advanced age.

Intraoperative blood volume loss according to gestational age at delivery among pregnant women with placenta accreta spectrum (PAS): an 11-year experience in Songklanagarind Hospital.

A retrospective study was conducted to evaluate the intraoperative blood volume loss in pregnant women with PAS according to gestational age at delivery. A total of 116 women were enrolled, 39 (33.6%) had an intraoperative massive blood loss (>5000 ml). The massive haemorrhage group had statistically significantly higher percentages of increta and percreta type than the non-massive haemorrhage group (94.9 vs. 67.5%, p < .001). Multiple linear regression analysis showed a decreasing trend of intraoperative blood loss after 34 weeks' gestation with the nadir period between 35 and 36+6 weeks' gestation, especially from 36-36+6 weeks' gestation which was statistically significant, p <.05. The perinatal morbidities from 36-36+6 weeks were not statistically significantly different from 37 weeks' gestation. Therefore, we recommend that pregnant women with PAS and stable clinical symptoms should be scheduled for caesarean hysterectomy from 36-36+6 weeks' gestation.Impact statementWhat is already known on this subject? Massive obstetric haemorrhage from PAS disorders is the main concern for caesarean hysterectomy among these patients as it leads to secondary complications including coagulopathy, multisystem organ failure, and death.What do the results of this study add? The amount of intraoperative blood loss in pregnant women who underwent caesarean hysterectomy due to PAS, was lowest from 36-36+6 weeks' gestation.What are the implications of these findings for clinical practice and/or further research? We recommend that pregnant women with PAS and stable clinical symptoms should be scheduled for caesarean hysterectomy from 36-36+6 weeks' gestation.

Validation of the Functional Assessment of Cancer Therapy with Cervical Cancer Subscale (FACT-CX) for Quality of Life in Thai Patients Prior to Chemoradiotherapy.

OBJECTIVE: Cervical cancer is the second most common cancer in Thailand. For cervical cancer, there is no cancer specific quality of life questionnaire. This study aims to develop and validate Thai FACT-CX. METHODS: The cross-sectional study included all women aged ≥18 years with stage IB2-IIIB who planned to undergo chemoradiotherapy. Those who did not understand Thai language, had other cancers (except for skin cancer), were diagnosed with impaired cognition and/or overt psychosis, and major depression were excluded. The FACT-CX comprises 42 items with 5 domains and a score range of 0-168. The WHOQOL-BREF comprises 26 items with 4 domains and a score range of 26-130. The participants were interviewed about demographic and clinical data. Both questionnaires were self-completed.  Factor analysis was used to compare our data with the previous structure. The reliability used Cronbach's alpha. Spearman's correlation determined relationship between the domains of the modified FACT-CX and WHOQOL-BREF. Both questionnaires were compared with socioeconomic and clinical variables using the Ranksum test and Kruskal-Wallis test. P-value > 0.05 considered significant. RESULTS: The 245 participants included. Expletory factor analysis revealed an accumulative variance of 0.42 with 4 factors. The internal consistency was 0.84, 0.81, 0.78, 0.77 and 0.90 for perception of self, suffering symptoms, family support, life resilience and total questions. There was correlation between the domains of the modified FACT-CX and WHOQOL-BREF.  Both the modified FACT-CX and WHOQOL-BREF could identify differences between the groups of patients. CONCLUSION: Finally, the Thai modified FACT-CX was found to be reliable and valid for measuring quality of life among untreated cervical cancer patients.

Adjunctive therapy of intravenous colistin to intravenous tigecycline for adult patients with non-bacteremic post-surgical intra-abdominal infection due to carbapenem-resistant Acinetobacter baumannii.

Post-surgical intra-abdominal infections (IAIs) due to carbapenem-resistant Acinetobacter baumannii (CRAB) are difficult to treat due to suboptimal peritoneal penetrations of several antimicrobial agents. Tigecycline has favorable outcomes of treating IAIs due to multidrug-resistant organisms but occurrence of breakthrough bacteremia has been observed because this agent has low serum level. Colistin has in vitro activity against CRAB but data on treatment of IAIs is limited due to poor peritoneal penetration. The purpose of this retrospective study is to explore the outcomes of adjunctive intravenous (IV) colistin to IV tigecycline in the treatment of IAIs caused by CRAB. Of 28 patients with non-bacteremic post-surgical IAIs due to CRAB, 14 patients received IV tigecycline alone and 14 patients received IV tigecycline with IV colistin. The 14-day, 30-day, in-hospital mortality rates, the rate of breakthrough bacteremia and the rate of bacterial eradication were not significantly different. The adjunctive therapy of IV colistin was associated with significantly higher rates of renal complications (10/14) than those receiving IV tigecycline alone (3/14) (P value = 0.023). In addition, the patients receiving adjunctive IV colistin had significantly more unfavorable non-clinical outcomes including longer length of hospital stay (P value = 0.049) and higher antimicrobial cost (P value = 0.008) and non-antimicrobial costs (P value = 0.037). In this study, adjunctive IV colistin to conventional IV tigecycline in the treatment of non-bacteremic post-surgical IAIs caused by CRAB did not yield clinical benefit but caused higher renal complication and unfavorable non-clinical outcomes.

Diagnostic Performance and Agreement of Preoperative, Intraoperative Evaluations, and Final Pathology for Lymphadenectomy and Lymph Node Involvement in Endometrial Cancer

Objective: To determine the accuracy of clinical parameters examined by preoperative and intraoperative evaluations compared with final histological results in patients with endometrial cancer, and to evaluate the application of preoperative investigations, intraoperative evaluations, and final histological results in predicting lymph node involvement Material and Method: The medical records of the patients diagnosed with endometrial cancer who had surgical staging between January 1, 2006 and December 31, 2012 at Songklanagarind Hospital were retrospectively reviewed. The agreement of clinical parameters identified through preoperative investigations and intraoperative evaluations with the final histology findings were calculated using kappa statistics. The diagnostic performance of preoperative investigations, intraoperative evaluations, and final histological results to predict lymph node involvement were calculated in terms of sensitivity, specificity, positive predictive value, and negative predictive value. Results: Preoperative investigations showed a slight to fair agreement whereas intraoperative evaluations had a fair to moderate agreement in detecting clinical parameters compared with the final histological results. Endocervical curettage and endometrial biopsy exhibited the highest sensitivity, pelvic ultrasonography the highest specificity, and intraoperative evaluations had a high-level sensitivity and specificity Conclusion: Preoperative investigations have role as an adjunctive evaluation, whereas intraoperative gross assessment remains the most accurate and useful method of detecting patients for lymphadenectomy.

Management and clinical outcomes of endometrial hyperplasia during a 13-year period in Songklanagarind Hospital.

BACKGROUND: Endometrial hyperplasia has long been considered a precursor of endometrial cancer but there is no consensus regarding its management. OBJECTIVE: To identify management practices and evaluate outcomes of treatments for women diagnosed with endometrial hyperplasia (EH). MATERIAL AND METHOD: The medical records of endometrial hyperplasia at Songklanagarind Hospital between January 2000 and December 2012 were retrospectively reviewed. RESULTS: Two hundred ninety seven patients were diagnosed with endometrial hyperplasia during the study period. Four patients who did not come for treatment and could not be contacted were excluded Therefore, 293 patients were included in the study. Simple hyperplasia (SH) was the most common diagnosis accounting for 79.2% of all cases, followed by complex hyperplasia (CH) 13.0%, complex atypical hyperplasia (CAH) 5.8%, and simple atypical hyperplasia (SAH) 2.0%. Seventy-eight percent (18/23) of the patients with atypical endometrial hyperplasia were treated by hysterectomy compared with 9.6% (26/270) of patients without atypia. Of the patients diagnosed with atypical EH, 30.4% (7/23) were associated with endometrial carcinoma. Overall, 6% (12/201) of the women who had initial non-hysterectomy management and had additional tissue taken to assess response, had persistent disease, and 1% (2/201) had progressive disease. Eleven patients (5.9%), who had an initial complete regression during the non-hysterectomy management, experienced a recurrence to EH and 2.1% (4/187) were found to have recurrence to endometrial cancer CONCLUSION: The majority of patients with atypical hyperplasia were managed by initial hysterectomy. The high risk of concomitant endometrial cancer supports this choice of treatment. In the non-atypical EH, the initial non-hysterectomy management was common but EH recurrence and progression to endometrial cancer after the initial regression occurs often. Therefore, long-term follow-up should be advised.
