The impact of surgical modality on self-reported body image, quality of life and survivorship after anterior resection for colorectal cancer – a mixed methods study

Background There is growing enthusiasm for robotic and transanal surgery as an alternative to open or laparoscopic surgery for colorectal cancer (CRC). We examined the impact of surgical modality on body image and quality of life (QOL) in patients receiving anterior resection for CRC. Methods We used a mixed-methods approach, consisting of a chart review and semistructured interviews with CRC patients, at least 8 months after surgery. We assessed cosmetic outcomes and QOL using validated questionnaires. Results Thirty patients were stratified into open (n = 8), laparoscopic (n = 12) and robotic (n = 10) groups. Mean body image scores were significantly higher (i.e., poorer body image) in patients receiving open surgery (mean difference [MD] +5.7 with laparoscopy, p < 0.001). Open surgery was more detrimental to physical function, including strenuous activities, prolonged ambulation and self-care (MD -11.6 with laparoscopy, p = 0.039). Patients receiving laparoscopic surgery reported superior role (MD +27.6 with open surgery, p = 0.002) and social function (MD +13.7 with open surgery, p = 0.042), including the ability to enjoy hobbies, family life and social activities. Surgical modality did not affect emotional and cognitive function or symptoms including genitourinary function, pain and defecation. Conclusion The negative impact of open surgery on body image and physical function warrants further educational interventions for patients. The protective effect of laparoscopy on role and function may be associated with "tumour factors" that are unaccounted for in the European Organization for Research and Treatment of Cancer questionnaires. Open surgery is detrimental to body image and physical function in patients receiving anterior resection for CRC. Prospective randomized studies are required to validate these findings.
