Analysis of the quality of surgical treatment of colorectal cancer, in 2008. A national study

Evaluation of quality parameters of rectal cancer surgery at the Coloproctology Unit of Hospital de Braga

“…Out of these patients, only one was submitted to urgent surgery; the others underwent elective surgery, in which the "sphincter sparing" resection could be performed, but due to the old age of the patients (mode of 80 years), with comorbidities associated with sphincter malfunctions, it was chosen to perform a definitive stoma in order to avoid the high risk of fecal incontinence. The rate of abominoperineal resections performed was 22.1% (n=33), which is within the limits described in literature, from 22 and 27% 41 , strongly influenced by the number of patients in the center. For tumors that are under the 8 cm from the anal margin, the described values range from 44.6 to 44.8% 41 .…”

For tumors that are under the 8 cm from the anal margin, the described values range from 44.6 to 44.8% 41 . This rate has been considered as one of the reliability criteria of the functional units [41][42][43] ; however, such criteria are being discussed 41,42 , since they depend on the percentage of RC located in the inferior 1/3 of the rectum that each unit presents; in this study, it was 27.5% of the cases.…”

“…In order to study the number of analyzed ganglia, the cohort value was established based on criteria of different surgeon associations, which recommend the analysis of at least 12 negative ganglia 41,46,47 . This way, it is possible to confirm with 90% accuracy that the patient is free of lymphatic invasion 38,48 .…”

Risk Factors for Anastomotic Leak After Colon Resection for Cancer

“…For this reason, the AL rates reported in retrospective studies based on national registers [15][16][17][18] from 50 hospitals, the AL rate was 5.6% after colonic resection. 23 However, urgent surgery cases were not included and the formation of a loop stoma was not an exclusion criteria, which justifies the lower AL found if compared to our study performed in the same national setting. In this study, 6 different variables were found to be independent risk factors for AL.…”
