We report on an endoscopic triple neurectomy in a female patient with vulvar carcinoma metastasized to the left groin with refractory neuropathic inguinodynia. Using a retroperitoneoscopic approach we resected the ilioinguinal, iliohypogastric, and genitofemoral nerves. The inguinodynia improved significantly; especially the reduced ability to walk was enhanced considerably. Endoscopic triple neurectomy could be a useful therapeutic option in refractory inguinal pain caused by local tumor manifestation.

Enlargement of the ilioinguinal nerve at the external inguinal ring is observed in 34% of patients undergoing primary open inguinal herniorrhaphy; in 88% of patients it occurs at the fascial edge where the hernia mushrooms with abdominal pressure. Compression neuropathy occurs near many anatomical nerve constriction sites and is associated with enlargement of the peripheral nerve accompanied by sensory changes.

To the best of our knowledge, the ropivacaine concentration required for ultrasound-guided ilioinguinal and iliohypogastric nerve block (INB) has not been reported. We designed this study to examine the 50% effective concentration (EC50) of ropivacaine for ultrasound-guided INB in children anesthetized with 2% sevoflurane.

Reported data suggest that 99% of transfemoral, transcatheter aortic valve implantations in the UK are performed under general anaesthesia. This before-and-after study is the first UK comparison of conscious sedation vs. general anaesthesia for this procedure. Patients who underwent general anaesthesia received tracheal intubation, positive pressure ventilation, radial arterial and central venous access and urinary catheterisation. Anaesthesia was maintained with propofol or sevoflurane. Patients who received conscious sedation had a fascia iliaca and ilioinguinal nerve block and low-dose remifentanil infusion, without invasive monitoring or urinary catheterisation. Recruitment took place between August 2012 and July 2015, with a 6-month crossover period between November 2013 and June 2014. A total of 88 patients were analysed, evenly divided between the two groups. Patients receiving conscious sedation had a shorter anaesthetic time (mean (SD) 121 (28) min vs. 145 (41) min; p < 0.001) and recovery room time (110 (50) min vs. 155 (48) min; p = 0.001), lower requirement for inotropes (4.6% vs 81.8%; OR (95% CI) 0.1 (0.002-0.050); p < 0.001) and a lower incidence of malignant dysrhythmia (0% vs 11.4%; p = 0.020). Conscious sedation appears a feasible alternative to general anaesthesia for this procedure and is associated with a reduced requirement for inotropic support and improved efficiency.

Triple neurectomy of the iliohypogastric (IHN), ilioinguinal (IIN), and genitofemoral (GFN) nerves is an available treatment option for chronic groin pain when conservative measures are ineffective. This research study attempted to define the variability of IHN, IIN, and GFN by categorizing variation and establishing a relationship to clinically significant landmarks.

The transversalis fascia plane block is a relatively new truncal block that targets the iliohypogastric and ilioinguinal nerves. It is gaining wider usage for its reliability to block these nerves as compared with the transversus abdominis plane block. The case presented here appears to be the first time that motor weakness has resulted from this block technique. It is suspected that central and proximal spread of local anesthetic toward the psoas muscle may have resulted in a partial lumbar plexus block.

Introduction: In this study we aimed to determine whether high-resolution ultrasound (US) can identify the iliohypogastric (IH), ilioinguinal (II), and genitofemoral (GF) nerves and their relations. Methods: This study, initially undertaken in cadavers, was followed by high-resolution ultrasound study in 30 healthy adult volunteers (180 nerves) by 2 musculoskeletal radiologists separately, using 2 different approaches (proximal-to-distal and distal-to-proximal). A 0-3 scale was used to assess nerve visibility. Location and course of the IH, II, and GF nerves and their relations to adjacent anatomical structures were analyzed. Results: Nerves and their terminal branches were visualized better with the distal-to-proximal approach (P<0.05). Visualization of the terminal branches was possible in up to 60% of volunteers. Discussion: High-resolution ultrasound (US) can identify the IH, II, and GF nerves at the level of the abdominal wall and the terminal branches in the majority of volunteers. © 2014 Wiley Periodicals, Inc.
