Background:
Colorectal cancer (CRC) is the commonly diagnosed malignancy presenting either in obstruction or without obstruction. Bowel obstruction (BO) is usually a complication of advanced cancer, significantly reducing the quality of life. We aimed to study the outcomes of these obstructed colorectal cancers requiring emergency intervention and compare it with nonobstructed cancers.
Materials And Methods:
In our observational comparative study, patients were divided into groups on basis of their presentation and site of lesion: nonobstructing colon group/obstructing colon group nonobstructing rectum group/obstructing rectum group.
Results:
A total of 232 patients with known modes of presentation between 2015 and 2018 were included; 144 colonic, 88 rectal carcinomas with 71 being completely obstructive ones. Our study showed higher recurrence in obstructive groups with local recurrence being more common. The median interval for recurrence was early in obstructive group (p < 0.001*). The overall 5-year survival rates were better in Nonobstructing colon group, (p = -0.046* in OR vs NOR) (p = -0.031* in OC vs NOC). 5-year disease-free survival rates statistically insignificant (p = 0.203 in NOC and OC groups), (p = 0.307 in NOR and OR groups). Immediate post-op, complications except for SSI, there was no significant difference between the two groups. Our study showed higher proportion of R0 resection in NOC groups as compared with obstructive groups (p = 0.021* in in OC vs NOC and p = 0.037* in OR vs NOR) with better lymph node retrieval in NOC groups.
Conclusion:
On comparing outcome of patients who had completed multi-modal therapy in both groups, there was significantly better outcome for patients who have presented without obstruction.
