• 1 other identifier: CERU_2024-034

Brief Summary

The objective of our study is to evaluate the efficacy of the laparoscopic robot-assited approach after 1 year of follow-up, on pain experience, and anxiety, depression, post-traumatic stress syndrome and quality of life.

Conditions

Pudendal Neuralgia

Keywords

pudendal; inferior cluneal; robot; surgery; decompression; neurolysis; laparoscopy

Outcome Measures

Primary Outcomes (1)

• Evaluate the efficacy of the surgical technique on pain experience related to pudendal and inferior cluneal chronic entrapment neuralgias, using a composite criteria (Numeric pain scale, time seated, PGIC score)

  Numeric pain scale (0 "no pain" to 10 "maximal pain"), time seated (\> 30 min,\> 60min or unlimited) Patients' Global Impression of Change (PGIC) scale (1 "very hightly improved" to 7 "very hightly worsened") are combined to create a composite criteria (significant improvement to complete improvement)

  Pré-operatively, 2 days, 4 months, 1 year after surgery

Secondary Outcomes (6)

• Report all complications during the follow-up

  2 days, 4 months, 1 year, 2 years, 3 years, 4 years and 5 years after surgery

• Evaluate the effect of the surgical technique on anxiety

  Pré-operatively, 2 days, 4 months, 1 year, 2 years, 3 years, 4 years and 5 years after surgery

• Evaluate the effect of the surgical technique on depression

  Pré-operatively, 2 days, 4 months, 1 year, 2 years, 3 years, 4 years and 5 years after surgery

• Evaluate the effect of the surgical technique on post-traumatic stress syndrome

  Pré-operatively, 2 days, 4 months, 1 year, 2 years, 3 years, 4 years and 5 years after surgery

• Evaluate the impact on quality of life

  Pré-operatively, 2 days, 4 months, 1 year, 2 years, 3 years, 4 years and 5 years after surgery

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

This cohort study is a pilot study to evaluate decompression of pudendal and inferior cluneal nerves using robot-assisted laparoscopy for entrapment neuralgias

You may qualify if:

• Patients over 18 years old
• Patients presenting a pudendal and inferior cluneal entrapment neuralgia with 5 positive"Nantes criteria", and failure of the medical treatment
• Patient having given consent after reading the information note

You may not qualify if:

• Absence of any "Nantes criteria",
• Patient non suitable for surgery/general anesthesia
