简要总结
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.
详细描述
Pudendal and inferior cluneal neuralgias are responsible for chronic pelvic perineal pain. The compression of both of the nerves are thought to be associated in approximately 25% of the pudendal neuralgias. The failure of the isolated pudendal decompression led in the early 2000s to the identification of an entrapment syndrome of the posterior femoral cutaneous nerve and its inferior cluneal branche around the ischial tuberosity. This subsequent neuralgia affects the posterior part of the perineum, lower buttock, and the posterior part of the thigh, without any associated neuro-vegetative symptoms, unlike in pudendal neuralgia. In case of failure of the medical treatment, the open trans-gluteal decompression was proposed as a gold standard. However, this technique remains invasive and requires a long recovery. In a previous study, the investigators demonstrated the feasibility of double decompression via a minimally invasive robot-assisted laparoscopic approach, and described a 4-step technique.

结局指标
主要结局
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)
时间窗: Pré-operatively, 2 days, 4 months, 1 year after surgery
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)

- Report all complications during the follow-up(2 days, 4 months, 1 year after surgery)
- Evaluate the effect of the surgical technique on depression(Pré-operatively, 2 days, 4 months, 1 year after surgery)
- Evaluate the effect of the surgical technique on post-traumatic stress syndrome(Pré-operatively, 2 days, 4 months, 1 year after surgery)
- Evaluate the impact on quality of life(Pré-operatively, 2 days, 4 months, 1 year after surgery)
- 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)
