Outcomes of the distal rectal cancer treatment depending on the type of sphincter-sparing surgery
The increase in mid-ampullary and lower ampullary rectal cancer with disappointing treatment results requires ongoing discussion, research, and improvement of the complex treatment.
We analyzed the results of complex treatment in 442 patients with stages II–III mid-ampullary and lower ampullary rectal cancer that underwent three types of sphincter-sparing surgeries, including low anterior resection (LAR), intersphincteric resection (ISR), and abdomino-anal resection of the rectum (AAR) at the second stage of complex treatment.
There was a significant difference between groups in terms of surgery type selection based on the distance from the tumor to the dentate line. When the tumor was located at a distance of 30 mm or less from the dentate line, LAR was performed in 16.4% of cases, whereas ISR and AAR were used in 96.58 and 58.09% of cases, respectively, which is statistically significant (P<0.001). Preventive stoma was used in 78.87% of LAR, 5.9% of ISR, and 6.62% of AAR, which had a significant difference (P<0.001). In the structure of postoperative complications, a group of typical complications (ІІІ–IV) was identified for the types of operations performed. Their frequency when performing LAR was 18.2%, ISR – 7.7%, and AAR – 8.1%, which was statistically significant (P=0.003). The frequency of local recurrences, depending on the type of surgery was not statistically significant (P>0.05), but had a direct correlation with the recurrence-free survival curves. Relapse-free and overall (3 years and 5 years) survival depending on the type of sphincter-preserving surgery did not have a significant difference according to the log-rank test.
The more types of surgical intervention surgeons have at their disposal, the more rational it is to select the one that will ensure the best treatment results.
