No Differences in the Prevalence and Intensity of Chronic Postsurgical Pain Between Laparoscopic Hysterectomy and Abdominal Hysterectomy: A Prospective Study.

OBJECTIVE

To compare the prevalence and characteristics of chronic postsurgical pain (CPSP) between laparoscopic hysterectomy (LH) and abdominal hysterectomy (AH) groups 3, 6, and 12 months after surgery, and to assess the impact of pain on the activities of daily living (ADL) of patients.

METHODS

The demographic characteristics, intraoperative clinical factors, and postoperative pain score were collected prospectively in patients scheduled for elective LH or AH for benign disease at our institution from July 2014 to June 2015. Patients were interviewed by telephone and followed up for pain assessment 3, 6, and 12 months after surgery. The prevalence, intensity, and specific locations of pain, as well as analgesic administration and impact on the ADL, were included in the questionnaire.

RESULTS

The results from 406 patients (225 patients in the LH group and 181 patients in the AH group) were obtained. Three months after surgery, the prevalence of CPSP was 20.9% in the LH group and 20.4% in the AH group. At 6 months, the prevalence of pain declined to 11.6% in the LH group and 9.4% in the AH group. At 12 months after surgery, only 13 (5.8%) patients in the LH group and 11 (6.1%) patients in the AH group complained about persistent pain. The prevalence of CPSP, as well as the average numerical rating scale pain scores at rest and during movement, during 12 months after surgery were not significantly different between the groups. CPSP after hysterectomy exhibited a negative impact on the ADL.

CONCLUSION

The prevalence and intensity of CPSP were not significantly different between patients undergoing LH or AH within 12 months after surgery. A tendency towards a reduction in chronic pain over time was documented. Chronic post-hysterectomy pain exhibited a negative impact on the ADL.
