ABSTRACT

BACKGROUND: Despite clinical and economic benefits, pain during outpatient hysteroscopy (OPH) remains a barrier to use. There is a lack of evidence to support routine use of one analgesic over another versus no analgesic. AIMS: To study the efficacy and safety of methoxyflurane analgesia during OPH. MATERIALS AND METHODS: A single-centre, randomised, double-blind, placebo-controlled experiment was performed; 90 patients were randomly assigned (1:1). Participants allocated to the treatment group (cases) received 3 mL of methoxyflurane through an inhaler. The control group received a placebo. The primary outcome was a mean difference in pain, via a change in Visual Analog Scale (VAS) score from baseline at diagnostic hysteroscopy. Secondary outcomes were a mean difference in VAS score with any subsequent operative procedures; a mean difference in VAS score at 15 min post-procedure; participant and clinician-reported adverse effects and events; and participant-reported procedure acceptability, adjuvant nitrous oxide (N2O2) use and a composite of 'distress'. RESULTS: During diagnostic hysteroscopy, there was a mean difference of 11.5 mm/100 (95% confidence interval (CI) 0.08-22.95), P = 0.05, with the lower score in the cases, compared with controls. During subsequent operative procedures, there was a mean difference of 15 mm/100 (95% CI 2.71-28.22), P = 0.02, with the lower pain score in the cases, compared with controls. There was no significant difference in pain 15 min post-procedure, participant- and clinician- reported adverse effects and events, procedure acceptability and the 'distress' composite. CONCLUSIONS: Methoxyflurane significantly reduced pain during OPH compared with placebo, for diagnostic as well as operative procedures. Furthermore, methoxyflurane was well tolerated, with no adverse events.

ABSTRACT

OBJECTIVE: To evaluate the rate of postoperative complications between conservative surgery and segmental resection in patients with rectal endometriosis. DESIGN: Single-center retrospective study. SETTING: University hospital. PATIENT(S): A total of 232 women undergoing surgery for deep endometriosis infiltrating the rectum up to 15 cm from the anus with at least involvement of the muscularis layer, stratified into two arms according to surgical technique. Subgroup analysis was performed in patients without previous therapeutic laparoscopy for endometriosis (n = 108). A propensity-score approach was used to correct for group differences. INTERVENTION(S): All patients underwent CO2-laser laparoscopic surgery: 61 underwent conservative surgery, and 171 had a segmental resection. MAIN OUTCOME MEASURE(S): Postoperative complication rate (Clavien-Dindo classification). RESULT(S): Clavien-Dindo type 1 and 2 complications did not differ between both groups. Clavien-Dindo type 3 complications were more frequent in the segmental resection group (1/61 [1.6%] conservative vs. 18/171 [10.5%] segmental), after propensity analysis only a trend was retained. In the subgroup analysis, no difference or trend was found (1/27 [3.7%] conservative vs. 5/81 [6.2%] segmental). A low rate of temporary diverting stoma was recorded: 24/232 (10.3%). CONCLUSION(S): A higher major complication (Clavien-Dindo ≥3) rate for segmental resections compared with conservative surgical treatment was shown in the overall population, although after correction for group differences this was attenuated to a trend only. However, in patients without previous therapeutic laparoscopy no significant difference or trend was found regardless of the surgical technique used. This not only suggests that redo/repeated surgery has a potentially increased morbidity, but also emphasizes the importance of a well executed primary surgery.
