Data management and statistical analysis were done using SPSS vs. 25 (IBM,
Armonk, NY). Quantitative data were assessed for normality using the Shapiro–
Wilk test and direct data visualization methods. Then, quantitative data were
summarized as mean and SD or medians and ranges. Categorical data were
summarized as numbers and percentages. Longo score and anorectal manometry
were compared at different times using repeated-measures analysis of variance.
Post hoc analyses were done using the Bonferroni method. Quality of life aspects
were compared pre- and postprocedure using paired t-test. McNemar test was
used to compare laxative use at different times. All statistical tests were two-sided.
P values less than 0.05 were considered significant.
Results
Preoperatively, 25 patients showed obstructed defecation symptoms.
Postoperatively, 23 (92%) patients have significant improvement in Obstructed
Defecation Syndrome (ODS) score; however, 40% of them are still depending
on laxatives. The remaining two patients (8%) with ODS have no significant
improvement in ODS score. Regarding anorectal manometry after surgery, mean
squeeze pressure showed significant increase, whereas all rectal sensation
showed significant decrease. Patient Assessment of Constipation Quality of Life
questionnaire score, total physical discomfort score, total psychosocial discomfort
score, and total worries and concerns score were significantly lower postoperatively,
whereas the total satisfaction score was significantly higher postoperatively. No
recurrences were found. |
