Abstract

Intersphincteric resection (ISR) has become an increasingly popular optional surgical tool for the treatment of very low rectal cancer. The purpose of this study was to assess the long-term oncological and functional outcomes of intersphincteric resection for T2 and T3 rectal cancer situated below 4 cm from the anal verge. A total of 62 consecutive patients with very low rectal cancer who underwent ISR from 2001 to 2010 were classified into standard ISR for T2 lesions (Group I, n = 24) and extended ISR for T3 lesions (Group II, n = 38). The 5-year overall survival rates were 95.8 % for group I and 94.7 % for group II. The 5-year recurrence-free survival rates were 87.5 % for group I and 86.8 % for group II. Bowel functions were evaluated at the 12(th) and 24(th) months after ileostomy closure in both groups. The frequency of bowel evacuation was higher in patients who underwent extended ISR than in those who underwent standard ISR at the 12(th) month (p < 0.05). However, at the 24(th) month, the frequencies decreased in both groups, exhibiting no significant difference. In the comparison based on the Kirwan classification, group I showed better continence status than group II but no significant difference. The Wexner scores of both groups revealed that the average score was 7.33 ± 2.8 in group I and 8.18 ± 2.9 in group II at the 12(th) month, and at the 24(th) month, the average score was 5.21 ± 1.7 in group I and 5.82 ± 1.9 in group II. There were no statistically significant differences between the two groups. Extended ISR with quadrant resection of the upper external sphincter achieved good post-operative continence status, OS and RFS. Extended ISR can thus be an alternative to abdominoperineal resection for very low rectal cancer without compromising the chance of cure and improving quality of life.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 April 2016.
All research outputs
#6,556,928
of 7,571,218 outputs
Outputs from BMC Surgery
#242
of 332 outputs
Outputs of similar age
#224,807
of 267,997 outputs
Outputs of similar age from BMC Surgery
#21
of 27 outputs
Altmetric has tracked 7,571,218 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 332 research outputs from this source. They receive a mean Attention Score of 2.5. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 267,997 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
