Function and Quality of Life After Transanal Excision of Rectal Polyps and Cancers

Purpose The purpose of this study was to determine the functional outcomes and health-related quality of life of patients after transanal excision of rectal cancers or polyps and to assess the relationship between functional outcomes and health-related quality of life. Methods All patients having a transanal excision at the Mount Sinai Hospital from 1989 to 2002 were included if the indication for surgery was a benign or malignant neoplasm. Physician charts were reviewed, and patients and their physicians were contacted to obtain follow-up information. Continence was assessed by using the Continence Score described by Jorge and Wexner and the Fecal Incontinence Quality of Life instrument by Rockwood and Lowry. Results Eighty-two patients fit the inclusion criteria (42 males; mean age, 71 ± 13.7 years). Of these, 29 had villous adenomas, 2 had carcinoids, and 1 had a hyperplastic polyp. Fifty had cancers, including 34 with T1, 14 with T2, and 2 with T3 cancers. Seven patients had a low anterior resection or abdominoperineal resection within two months of transanal excision because of advanced features of cancer. Five patients had salvage abdominoperineal resections or low anterior resections for local recurrences. Five patients died of rectal cancer (including 3 who had salvage surgery) and an additional seven patients died of other causes. Functional results were assessed in 58 of 61 eligible patients. The mean Continence Score postoperatively was 3.5 ± 3.9 compared with 2.4 ± 3.7 preoperatively (P = 0.03). The mean Fecal Incontinence Quality of Life scores after surgery in all patients were 3.9 ± 0.3, 3.6 ± 0.6, 3.7 ± 0.3, 3.7 ± 0.6 in the domains of lifestyle, coping, depression, and embarrassment, respectively, after surgery, indicating high quality of life. Using Spearman’s correlation, we found that the continence scores after surgery correlated well with the Fecal Incontinence Quality of Life scores. In the domains of lifestyle (Spearman’s correlation = −0.69), coping and behavior (Spearman’s correlation = −0.7), and embarrassment (Spearman’s correlation = −0.61) but did not correlate well with the domain of depression (Spearman’s correlation = −0.17). Conclusions Although functional results are worsened in a minority of patients after transanal excision, quality of life is high in the majority of patients.
