BACKGROUND: Low back pain may arise from disorders of the sacroiliac joint in up to 30% of patients. Radiofrequency ablation (RFA) of the nerves innervating the sacroiliac joint has been shown to be a safe and efficacious strategy. OBJECTIVES: We aimed to develop a new RFA technique to relieve low back pain secondary to sacroiliac joint disorders. STUDY DESIGN: Methodology development with validation through prospective observational non-randomized trial (PONRT)...

The treatment of failed back surgery syndrome (FBSS) can be equally challenging to surgeons, pain specialists, and primary care providers alike. The onset of FBSS occurs when surgery fails to treat the patient's lumbar spinal pain. Minimizing the likelihood of FBSS is dependent on determining a clear etiology of the patient's pain, recognizing those who are at high risk, and exhausting conservative measures before deciding to go into a revision surgery. The workup of FBSS includes a thorough history and physical examination, diagnostic imaging, and procedures...

OBJECTIVE: Low back pain, caused intervertebral disc degeneration has been treated by thermal annuloplasty procedure, which is a non-surgical treatement. The theoretical backgrounds of the annuloplasty are thermal destruct of nociceptor and denaturization of collagen fiber to induce contraction, to shrink annulus and thus enhancing stability. This study is about temperature and its distribution during thermal annuloplasty using 1414 nm Nd : YAG laser. METHODS: Thermal annuloplasty was performed on fresh human cadaveric lumbar spine with 20 intact intervertebral discs in a 37℃ circulating water bath using newly developed 1414 nm Nd : YAG laser...

A Caucasian man aged 28 years with a history of pancreatitis presented with fatigue, intermittent melaena and severe anaemia. Symptomatic treatment for anaemia was coupled with thorough investigation to localise the source of gastrointestinal haemorrhage. Two oesophagogastroduodenoscopies and colonoscopies failed to identify a cause. CT abdomen revealed splenomegaly secondary to splenic vein thrombosis with evidence of portal hypertension and small collateral vessels. A CT mesenteric angiogram revealed a splenic artery pseudoaneurysm as the likely source of bleeding...

BACKGROUND: One of the potential side effects with radiofrequency ablation (RFA) includes painful cutaneous dysesthesias and increased pain due to neuritis or neurogenic inflammation. This pain may require the prescription of opioids or non-opioid analgesics to control post-procedural pain and discomfort. OBJECTIVES: The goal of this study is to compare post-procedural pain scores and post-procedural oral analgesic use in patients receiving continuous thermal radiofrequency ablation versus patients receiving pulsed dose radiofrequency immediately followed by continuous thermal radiofrequency ablation for zygopophaseal joint disease...

As many as 62% low back pain patients can have sacroiliac joint (SIJ) pain. There is limited (to poor) evidence in regards to long-term pain relief with therapeutic intra-articular injections and/or conventional (heat or pulsed) radiofrequency ablations (RFAs) for SIJ pain. We report our pain-clinic experience with peripheral nerve field stimulation (PNFS) for two patients of intractable SIJ pain. They had reported absence of long-term pain relief (pain relief >50% for at least 2 weeks postinjection and at least 3 months post-RFA) with SIJ injections and SIJ RFAs...

Low back pain (LBP) is a major medical and economical problem, because of its high incidence. Indeed, 70-85% of adult people will suffer from this kind of pain once in their life. We will focus in this article on chronic LBP, which represent an annual prevalence of 30% and more specifically on mechanical pain, with our without radiation into the legs. In case of failure of traditional analgesia combining drugs and physical therapies, we can propose interventional pain relief. This involves a series of diagnostic blocks (medial branch blocks), followed by the treatment (radiofrequency ablation)...

PURPOSE: About 10-40% of chronic low back pain cases involve facet joints, which are commonly treated with lumbar medial branch (MB) radiofrequency neurotomy. Magnetic resonance imaging-guided focused ultrasound (MRgFUS), a non-invasive, non-ionising ablation modality used to treat tumours, neuropathic pain and painful bone metastasis can also be used to disrupt nerve conduction. This work's purpose was to study the feasibility and safety of direct MRgFUS ablation of the lumbar MB nerve in acute and subacute swine models...

OBJECTIVES: Hydrodiscectomy is a new technique used for percutaneous spinal discectomy that employs a high-intensity stream of water for herniated disc ablation and tissue aspiration. No previous clinical study has examined the effects of percutaneous hydrodiscectomy. The aim of this study is to evaluate the outcomes of hydrodiscectomy compared to open microdiscectomy regarding pain, function, satisfaction, complications and recurrence rates. METHODS: In this randomized clinical trial, patients referred to our tertiary hospital for lumbar back pain were recruited and included in the study if they had disc protrusion or small herniation in only one level, without neurological deficits and with no resolution after six weeks of conservative treatment...

UNLABELLED: The management of pain due to cancer is challenging and often requires invasive therapy in addition to medication management. Intrathecal drug delivery is a form of advanced therapy that delivers medication locally in the intrathecal space while reducing systemic side effects associated with high doses of opioids. Although risks associated with intrathecal drug delivery are low, some common complications include dislodgement, kinking, or fracture of the catheter, bleeding, neurological injury, infection, and cerebrospinal leaks...

BACKGROUND: MR-guided focused ultrasound (MRgFUS) might be a very safe and effective minimally invasive technique to treat facet joint pain caused by arthritis and other degenerative changes. However, there are still safety concerns for this treatment and challenges regarding MR imaging and temperature mapping due to susceptibility effects between the bone and soft tissue near the joint, which has resulted in poor MR image quality. The goal of this research was to evaluate multiple magnetic resonance imaging (MRI) pulse sequences for characterizing ablated lumbar facet joint lesions created by high-intensity focused ultrasound (FUS) and compare the findings to histological tissue assessment...

We report 2 cases of successful treatment of neck and back pain with bipolar radiofrequency ablation (RFA) of the cervical and lumbar facet joints in patients with an automatic implantable cardioverter defibrillator (AICD).Two patients with complex cardiac histories and AICD devices were treated with bipolar RFA of the facet joints. One presented with axial neck pain and the other with axial back pain. The histories and physical examinations were consistent with facetogenic pain. Diagnostic medial branch block resulted in more than 70% pain relief lasting for several days, allowing patients to perform routine daily activities without significant pain...

AIM: Radiofrequency ablation (RFA) is commonly used for the treatment of early hepatocellular carcinoma. However, it requires time to ablate sufficient areas, resulting in increased burden for the patients and operators. We introduce a novel and simple method to overcome this problem. METHODS: We placed the grounding pad on the back (Back group) instead of the thigh of the patient (Thigh group). To reveal the effect of this method, we randomly assigned the patients into the two groups and compared the outcome...

Fistula in ano is a very common presentation to colorectal clinic. Embarrassment due to the symptoms makes accurate estimations of incidence difficult. It is estimated that up to 40% of peri-anal abscess will be accompanied by or preceded by a fistula. Fistulae can be classified into simple fistulae that involve no or minimal sphincter muscle and complex, which involve significant amounts of the anal sphincter muscle, possibly with multiple tracts. For complex fistulae a seton suture is usually placed through the tract and out through the anus to form a loop allowing pockets of sepsis to drain internally and externally and a mature tract of fibrous tissue to develop...

Urine leak after nephron-sparing surgery is a difficult and morbid situation that may delay recovery and necessitate additional hospitalization and intervention. The use of cryoablation to treat a 34-year-old woman with persistent urine leak after robotic-assisted partial nephrectomy is described. Surgery was performed to treat ureteral duplication that resulted in recurrent urinary tract infections and back pain. Cryoablation was performed with computed tomography guidance, targeting urine extravasation observed after the administration of intravenous contrast medium...
