Incidence of The Bowel, Bladder, and Sexual Dysfunction Following Surgery for Colorectal Malignancy

It was a cross-sectional study at Bir Hospital and the duration of the study was from December 2014 to December 2017. Here, all the patients who underwent LAR and APR following neoadjuvant chemoradiotherapy were included. And, all the patients with recurrence after surgery, lost to follow up, benign disease, who did not undergo neoadjuvant chemoradiotherapy, and who underwent trans-anal excision were excluded from the study. In our study, the independent variable will be the type of surgery done for colorectal malignant disease. And the dependent variables will be the postoperative complications in the form of immediate and delayed complications. Immediate could be infectious or non-infectious complications and delayed (long term) complications could be bowel, bladder, and sexual dysfunction respectively.

Data collection was done using structured Performa that included all the demographic parameters, examination findings which included the data regarding neoadjuvant chemoradiotherapy and type of surgery (LAR and APR) were included. The laboratory parameters were also included. All the operative and post-operative details were included regarding bowel, bladder, and sexual dysfunction. And validated tools were used to calculate and analyze data.

LARS Score Questionnaire: The aim of this questionnaire was to assess the bowel function using a validated questionnaire.6 The LARS consists of five questions and can be used to generate an overall score that translates into no LARS (score 0-20), minor LARS (21-29), and major LARS (30-42) respectively.

IPSS Questionnaire: Assessment of bladder dysfunction was assessed by the validated questionnaire of International Prostatic Symptoms Score (IPSS) for bladder dysfunction.8 For the evaluation of preoperative and postoperative bladder function, a urologic history and residual urine volume measurements by ultrasound were done.

Sexual Function Evaluation: In the early period after surgery sexual function was measured using the validated questionnaire - the International Index of Female Sexual Function (IFSF) for females and the International Index of Erectile Function (IIEF) for males. These tools helped to assess the impact of a specific treatment modality by evaluating different sexual function domains. Our study group was small, so we did not classify the groups into mild, moderate, and severe dysfunction groups. We did the overall long term assessment of the patients who came for the follow-up. These specific questionnaires were asked and the assessment was done for the overall dysfunctions.
