RESUMO
INTRODUCTION AND HYPOTHESIS: We aimed to clarify the frequency of cul-de-sac obliteration in patients undergoing POP surgery. METHODS: We retrospectively reviewed patients who underwent laparoscopic POP surgery at our hospital between April 2017 and September 2021. RESULTS: In total, 191 cases were included in the analysis. Ten patients (5.2%) had cul-de-sac obliteration. No difference in age (73 years vs. 72 years, P = 0.99), parity (2 vs. 2, P = 0.64), or body mass index (BMI) (25.7 kg/m2 vs. 24.7 kg/m2, P = 0.34) was observed between the cul-de-sac obliteration and normal groups. No significant differences were observed in the rate of previous abdominal surgery (50.0% vs. 32.6%, P = 0.46), rate of POP - quantification system (POP-Q) ≥ 2 posterior prolapse (40.0% vs. 46.4%, P = 0.98), and effect of defecation symptoms on the prolapse quality of life (p-QOL) score (vaginal bulge emptying bowels: 2.5 vs. 3.5, P = 0.15; empty bowel feeling: 3 vs. 3, P = 0.72, constipation: 3.5 vs. 3, P = 0.58; straining to open bowels: 3.5 vs. 3, P = 0.82; empty bowels with fingers: 1 vs. 1, P = 0.55) between the cul-de-sac obliteration and normal groups. Multivariate analysis of risk factors for the cul-de-sac obliteration was performed for age, number of births, previous abdominal surgery, and presence of rectocele; however no significant risk factors were extracted. CONCLUSION: Predicting cul-de-sac obliteration preoperatively in patients undergoing POP surgery based on age, number of previous surgeries, previous abdominal surgeries, rectocele, and defecation symptoms is difficult.
