Prevalence of chronic pain syndrome in patients who have undergone hallux valgus percutaneous surgery: a comparison of sciatic-femoral and ankle regional ultrasound-guided nerve blocks

Background Chronic pain syndrome (CPS) is a common complication after operative procedures, and only a few studies have focused on the evaluation of CPS in foot-forefoot surgery and specifically on HV percutaneous correction. The objective of this study was to compare postoperative pain levels and incidence of CPS in two groups of patients having undergone femoral-sciatic nerve block or ankle block regional anaesthesia before hallux valgus (HV) percutaneous surgery and the association between postoperative pain levels and risk factors between these patient groups. Methods A consecutive patient series was enrolled and evaluated prospectively at 7 days, 1, 3 and 6 months after surgery. The participants were divided into two groups according to the regional anaesthesia received, femoral-sciatic nerve block or ankle block, and their outcomes were compared. The parameters assessed were postoperative pain at rest and during movement by the numerical rating scale (NRS), patient satisfaction using the Visual Analogue Scale (VAS), quality of life and return to daily activities. Statistical analysis was performed. Results One hundred fifty-five patients were assessed, 127 females and 28 males. Pain at rest (p < 0.0001) and during movement (p < 0.0001) significantly decreased during the follow-ups; at 6 months, 13 patients suffered from CPS. Over time, satisfaction remained stable (p > 0.05), quality of life significantly increased and patients returned to daily activities and work (p < 0.0001). No significant impact of type of anaesthesia could be detected. ASA 3 (p = 0.043) was associated to higher pain during movement; BMI (p = 0.005) and lumbago (p = 0.004) to lower satisfaction. No operative-anaesthetic complications were recorded. Postoperative pain at rest and during movement improved over time independently of the regional block used, with low incidence of CPS at last follow-up. Among risk factors, only a higher ASA was associated to higher pain during movement, while higher BMI and lumbago to lower satisfaction. Conclusions Both ultrasound-guided sciatic-femoral and ankle blocks were safe and effective in reducing postoperative pain with low incidence of CPS at last follow-up.

A modern view on tubeless percutaneous nephrolithotomy

Urolithiasis ranks second among urological diseases, after inflammatory processes, and first among surgical interventions in urological hospitals. The problem of this disease treatment is a long-term rehabilitation and disablement, which entails a significant increase in costs and requires changes in the tactics of treatment of patients. Since its introduction until today, percutaneous nephrolithotomy (PCNL) is the standard treatment for nephrolithiasis with a stone size of more than 1.5–2.0 cm. In its standard version, PCNL ends with the placement of nephrostomy catheter through the formed parenchymal channel, but there are techniques of the surgery completion either without nephrostomy catheter with a JJ stent – tubeless PCNL, or without nephrostomy and JJ stent at all – totally tubeless PCNL. However, nowadays, the use of tubeless and totally tubeless techniques is one of the most controversial topics in percutaneous nephrolithotomy in terms of safety and efficacy in their application. Aim. To analyze the results and safety of percutaneous nephrolithotomy by means of tubeless and totally tubeless techniques based on scientific evidence. Analysis of the scientific literature shows that tubeless and totally tubeless PCNL techniques are a safe method of percutaneous surgery and their application reduces pain and analgesic requirements in the postoperative period, shortens the length of postoperative hospital stay, and enhances recovery after surgery in patients, therefore resulting in cost-saving treatment. Conclusions. Tubeless and totally tubeless PCNLs are recommended for widespread use in urological practice, but it is worth to mention that these techniques should be performed in selected patients and by an operating surgeon with significant experience in percutaneous surgery.

Percutaneous Chevron and Akin (PECA) Osteotomies for Severe Hallux Valgus Deformity With Mean 3-Year Follow-up

Background: Patients with severe hallux valgus deformity present technical and operative challenges with high rates of recurrence and residual deformity. The clinical and radiologic outcomes of percutaneous surgery for severe hallux valgus are not known. Methods: A retrospective review of consecutive patients with a hallux valgus angle (HVA) >40 degrees or intermetatarsal angle (IMA) >20 degrees who underwent third-generation percutaneous chevron and Akin osteotomy (PECA) for hallux valgus deformity correction. Results: Between December 2012 and August 2019, 59 feet in 50 patients underwent PECA. Preoperative and follow-up radiographic data were available for 53 feet (89.8%). Postoperative clinical patient-reported outcome measures and satisfaction results were available for 51 feet (86.4%). The mean clinical and radiographic follow-up was 3.1 years and the mean postoperative Manchester-Oxford Foot Questionnaire Index score was 15.1. There was a statistically significant improvement ( P < .001) in both IMA and HVA following surgery (IMA 17.5-5.1 degrees; HVA 44.1-11.5 degrees). All patients reported they were satisfied with their outcome, with 76.8% reporting they were highly satisfied. The hallux valgus recurrence rate was 7.5%. Conclusion: Percutaneous surgery for severe hallux valgus deformity can achieve a large deformity correction, patient satisfaction, and quality of life, with reasonable rates of residual deformity and low rates of recurrence. Level of Evidence: IV

Comparison of first-time microvascular decompression with percutaneous surgery for trigeminal neuralgia: long-term outcomes and prognostic factors

Objective Common surgical treatments for trigeminal neuralgia (TN) include microvascular decompression (MVD) and percutaneous procedures (glycerol rhizolysis; thermocoagulation; and balloon compression). Although the efficacy of each procedure has been documented, direct comparisons of their relative efficacies for TN are lacking. We aimed to directly compare long-term outcomes after first-time MVD with percutaneous surgery in primary (idiopathic and classical) TN and identify predictors of outcome. Methods We conducted a retrospective analysis of prospectively collected data on 185 patients undergoing MVD and 129 undergoing percutaneous surgery. Procedures were performed by one of two neurosurgeons in a single centre; an independent observer collected long-term follow-up data by interviews, using the same outcome measures for all procedures. Results MVD patients were younger than those undergoing percutaneous surgery (P <.001). MVD provided superior initial pain relief (P <.001): 87.0% had Barrow Neurological Institute class I or II pain scores after MVD compared with 67.2% after percutaneous surgery. The complication rate for percutaneous procedures was 35.7% and for MVDs was 24.9% (P =.04), including minor and transient complications. Kaplan-Meier analysis demonstrated that MVD provided longer pain relief than percutaneous procedures (P <.001); 25% of patients had recurrence at 96 months following MVD compared with 12 months after percutaneous surgery. Subgroup analysis showed that balloon compression provided more durable relief amongst percutaneous procedures. Multivariate analysis revealed that post-operative numbness and age were prognostic factors for percutaneous procedures (P =.03 and .01, respectively). Conclusions MVD provides better initial pain relief and longer durability of relief than percutaneous surgery, although carrying a small risk of major complications. Amongst percutaneous procedures, balloon compression gave the most durable relief from pain. Older age and post-operative numbness were predictors of good outcome from percutaneous surgery. These results can help clinicians to counsel patients with primary TN on neurosurgical treatment selection for pain relief.

A clinical example of percutaneous nephrolitolapaxy of complete staghorn kidney stone in patient with lumbar renal dystopia

Urinary stone disease (urolithiasis, UL) is one of the most prevalent diseases in the world affecting almost 3% of the population, mainly people of working age from 40 to 50 years, which determines the relevance of a comprehensive study of this disease. Meanwhile, few works devoted to the interrelation between UL and renal abnormalities have been published. The unusual nature of angioarchitectonics, location, shape, structure, number of kidneys and upper urinary tract make it difficult to perform both open and endoscopic surgery thus preconditioning the reduction of their effectiveness and increasing the number of complications. In recent years, the number of indications for open stone surgery has significantly decreased. Percutaneous surgery has become widely used in endourology, including treatment of abnormal kidneys. However, the issues of percutaneous nephrolitolapaxy (PCNL) in kidney abnormalities have not been completely resolved yet. The article presents a clinical case of successful percutaneous nephrolitolapaxy of complete coral-shaped kidney stone (Class 4) in a patient with lumbar renal dystopia.
