Neuropathic painful complications due to endopelvic nerve lesions after robot-assisted laparoscopic prostatectomy: Three case reports

Research output: Contribution to journalArticle

Abstract

RATIONALE: Robot-assisted laparoscopic prostatectomy (RALP) is the most frequent strategy used for the surgical remedy of patients with localized prostate cancer. Although there is awareness about potential patient positioning nerve injuries, iatrogenic nerve lesions are less described in the literature. Here, we report 3 cases of patients who presented with neuropathic painful complications due to RALP-associated nerve lesions. PATIENT CONCERNS: A 62-year-old patient (case 1), a 72-year-old male (case 2), and a 57-year-old patient (case 3) presented at the clinic with symptoms of neuropathic pain after RALP surgery. DIAGNOSIS: Patients were diagnosed with a potential injury of different branches of the pudendal nerve (cases 1 and 2), and left obturator nerve (case 3). INTERVENTIONS: Patients underwent multimodal pharmacologic treatment through pregabalin, weak opioids, strong opioid, paracetamol, and adjuvants. In cases 2 and 3, a multidisciplinary approach was needed. As the patients responded to conservative treatment, invasive approaches were not necessary. OUTCOMES: After treatment, the patients of case 1 showed pain relief after 4 days, paresthesia resolved in 15 days, whereas the anal crushing sensation lasted for approximately 1 month. In case 2, after 4 weeks of treatment, the patient experienced a considerable decrement in pain intensity with complete response after 4 months. In case 3, pain relief was achieved after 2 days, motor symptoms recovery after 2 weeks, and neuropathic features resolved completely after 5 weeks although the obturator sign resolved within 2 months. LESSONS: The RALP-associated neurologic injuries may occur even when performed by highly experienced surgeons. A better understanding of the potential iatrogenic nerve lesions can surely allow an improvement in the surgical technique. A multidisciplinary approach and early multimodal pain strategy are mandatory for managing these complications.
