Patients and Methods

Between November 2010 and November 2016, 497 patients (age 55 ± 14 years) were submitted to laser haemorrhoidoplasty with a 1470 nm diode laser in the centre for minimally invasive proctology in Siegen District Hospital. All operated patients were included in the study. Perioperative clinical and technical data up to 6 weeks and follow-up data up to 6 months were analysed prospectively.

Results

The mean duration of operation was 14 min (± 5.2). A mean of 2.7 knots of 2.7 size were treated per patient. The mean postoperative pain was 2.5/10 (VAS). Long-term symptom relevance was 86%, and patient satisfaction 91%. Complications occurred in 49 patients (9.9%): bleeding 1.8%, infection 1%, urine retention 1.8%, oedema/thrombosis/prolapse 6.6%. 8.8% of patients suffered a relapse within 6 months. There were significant differences in pain on the day of the operation, and the parameters mucopexia, 3 treated segments and energy level > 500 J (p < 0.05). Complications were more common when mucopexia was performed, with 3 treated knots and energy consumed per patient > 500 J. The only significant difference was for energy level > 500 J (p < 0.05).

Conclusion

LHP is a safe, low pain and minimally invasive surgical procedure with long-term good patient acceptance and satisfaction and is suited for routine work. The energy applied should be reduced to a minimum. Complication rates are largely comparable with those of other minimally invasive conventional methods. Additional prospective studies must be performed, particularly in comparison to the Parks method, which gives similar functional results. With circular confluent findings, LHP cannot replace stapler hemorrhoidopexia.
