Background: Functional results after low anterior resection for rectal cancer are an issue of increasing attention among colorectal surgeons and others interested in this subject. The aim of the study to compare the nocturnal bowel movement and frequency of bowel movement between TCP & SA groups after low anterior resection. This study also compare the urgency of bowel movement between two groups and the incontinence of flatus & loose stool between two groups. Methods: This prospective observational study was carried out in the Department of Surgery Bangabandhu Sheikh Mujib Medical University Shahbag, Dhaka, during 1st January 2016 to 30lh June 2017. For this purpose, a total of 40 patients with low rectal cancer undergoing low anterior or ultra-low anterior resection with TCP or straight anastomosis in the above mentioned hospital were both male & female patients and age group (18-75 years) were enrolled in this study. Data was expressed as mean with standard deviation (Mean±SD). Collected Data were statically analyzed applying student‘t’ test and chi-square test using SPSS-24. P value of <0.05 was considered statically significant. Results: The mean age was 45.9±13.29 years in group-I and 47.55±10.86 years in group-II. Male female ratio was 1.2:1 in TCP group and 1.5:1 in SA group. Anal tone on 3rd month 1(5.0%) in group-I and 10(50.0%) in group-II. Anal tone was significantly (p<0.05) improve in group I at 3rd month. Finger grip on 3rd month 18(90.0%) in group-I and 19(95.0%) in group-II. Finger grip was almost alike between two group, no statistical significant (p>0.05) was found between two groups. Conclusion: Most of the patients were in 5th and above decade and male predominant. Transverse coloplasty pouch anastomosis provided not only better functional results than straight anastomosis, but also improved quality of life, thus may be the better choice.
