The effect of colorectal surgery in female sexual function, body image, self-esteem and general health: a prospective study.

OBJECTIVE: To evaluate women's sexual function, self-esteem, body image, and health-related quality of life after colorectal surgery. SUMMARY BACKGROUND DATA: Current literature lacks prospective studies that evaluate female sexuality/quality of life after colorectal surgery using validated instruments. METHODS: Sexual function, self-esteem, body image, and general health of female patients undergoing colorectal surgery were evaluated preoperatively, at 6 and 12 months after surgery, using the Female Sexual Function Index, Rosenberg Self-Esteem scale, Body Image scale and SF-36, respectively. RESULTS: Ninety-three women with a mean age of 43.0 +/- 11.6 years old were enrolled in the study. Fifty-seven (61.3%) patients underwent pelvic and 36 (38.7%) underwent abdominal procedures. There was a significant deterioration in overall sexual function at 6 months after surgery, with a partial recovery at 12 months (P = 0.02). Self-esteem did not change significantly after surgery. Body image improved, with slight changes at 6 months and significant improvement at 12 months, compared with baseline (P = 0.05). Similarly, mental status improved over time with significant improvement at 12 months, with values superior than baseline (P = 0.007). Physical recovery was significantly better than baseline in the first 6 months after surgery with no significant further improvement between 6 and 12 months. Overall, there were no differences between patients who had abdominal procedures and those who underwent pelvic dissection, except that patients from the former group had faster physical recovery than patients in the latter (P = 0.031). When asked about the importance of discussing sexual issues, 81.4% of the woman stated it to be extremely or somewhat important. CONCLUSION: Surgical treatment of colorectal diseases leads to improvement in global quality of life. There is, however, a significant decline in sexual function postoperatively. Preoperative counseling is desired by most of the patients.

The efficacy of a nerve stimulator (Cavermap) to enhance autonomic nerve identification and confirm nerve preservation during total mesorectal excision.

PURPOSE: Sexual dysfunction after total mesorectal excision may be caused by injury to the autonomic nerves. During surgery, nerve identification is not always achieved, and, to date, there has been no method to objectively confirm nerve preservation. The aim of this study was to assess the efficacy of a nerve-stimulating device (CaverMap) to assist in the intraoperative identification of the autonomic nerves during total mesorectal excision, and objectively confirm nerve preservation after proctectomy is completed. PATIENTS AND METHODS: Sexually active consecutive male patients undergoing total mesorectal excision were prospectively enrolled in this study. During pelvic dissection, the surgeon attempted to localize the hypogastric and cavernous nerves. CaverMap was used to confirm these findings and to facilitate the identification in cases of uncertainty. At the completion of proctectomy, the nerves were restimulated to ensure preservation. Factors that could affect the surgeon's ability to localize the nerves and CaverMap to confirm this were evaluated. RESULTS: Twenty-nine male patients with a median age of 58 years were enrolled in this study. An attempt to visualize the hypogastric nerves during dissection was made in 26 patients; the surgeon was able to identify the nerves in 19 (73 percent) patients. CaverMap successfully identified the nerves in six of the seven remaining patients, and failed to identify them in only one case. An attempt to localize the cavernous nerves during dissection was made in 13 patients, of which localization was successful in 8 (61.5 percent) patients. CaverMap improved the identification rate in four of the remaining five patients. After proctectomy, CaverMap successfully confirmed the preservation of both hypogastric and cavernous nerves in 27 of 29 (93 percent) patients. A history of previous surgery statistically correlated with failure to identify the hypogastric nerves by the surgeon (P = 0.005). There were no adverse events related to use of the device. CONCLUSION: CaverMap may be a useful tool to facilitate identification of the pelvic autonomic nerves during total mesorectal excision and to objectively confirm nerve preservation.
