Materials And Methods: Patients who underwent biparametric MRI over a 12-month period from January 2022 to December 2022 and were diagnosed with PIRADS 3 lesion in the peripheral zone were included in the study. No patient received dynamic contrast enhancement.

Nail it! vision-based drift correction for accurate mixed reality surgical guidance.

Purpose: Mixed reality-guided surgery through head-mounted displays (HMDs) is gaining interest among surgeons. However, precise tracking of HMDs relative to the surgical environment is crucial for successful outcomes. Without fiducial markers, spatial tracking of the HMD suffers from millimeter- to centimeter-scale drift, resulting in misaligned visualization of registered overlays.

Clinical Performance Status and Technical Factors Affecting Outcomes from Percutaneous Transhepatic Biliary Interventions; A Multicentre, Prospective, Observational Cohort Study.

Purpose: The purpose of this study was to evaluate the predictive value of a 'Modified Karnofsky Scoring System' on outcomes and provide real-world data regarding the UK practice of biliary interventions.

Materials And Methods: A prospective multi-centred cohort study was performed. The pre-procedure modified Karnofsky score, the incidence of sepsis, complications, biochemical improvement and mortality were recorded out to 30 days post procedure.

Percutaneous caecostomy for the management of closed loop large bowel obstruction: A delayed complication of severe gallstone pancreatitis.

Colonic complications following pancreatitis are unusual events ranging from 1% to 15%. In a patient with a hostile abdomen and multiple previous laparotomies, surgical management of a closed-loop large-bowel obstruction risks significant morbidity and mortality for the patient, necessitating other strategies for management. Caecostomy in the management of large bowel obstruction is an often forgotten weapon in the general surgeons' armoury.

Orthotopic neobladder perforation: an unusual presentation of small bowel obstruction.

Orthotopic bladder reconstruction is becoming increasingly popular in patients who have undergone radical cystectomy. One of the rare complications is spontaneous rupture, which presents with various symptoms, but in particular, abdominal pain. We report a case of orthotopic bladder perforation in a patient who presented with the symptoms and signs of small bowel obstruction.

Balloon dilatation of benign rectal anastomotic strictures -- a review.

Background: The occurrence of anastomotic stricture at the level of the rectum gives rise to three broad therapeutic options, namely major pelvic and abdominal revisional surgery, faecal diversion (stoma), or local revision by transanal approaches (including endoscopic and fluoroscopic). This article updates the current evidence and focuses on the results of the balloon dilatation technique.

Methods: A Medline search was carried out using the search terms (dilatation OR dilatation) AND (stricture OR strictures OR stenosis OR stenotic) AND (rectum OR rectal).

Usage of prophylactic radiologically inserted gastrostomy in head and neck cancer patients.

Aim: To assess outcomes and usage rate of prophylactic radiologically inserted gastrostomy (RIG) in head and neck cancer (HNC) patients.

Materials And Methods: Outcome data of all HNC patients who underwent prophylactic RIG over a 22-month period (November 2007 to September 2009) in a tertiary referral centre were collected retrospectively. Thirty-day mortality, major and minor complication rates, and subsequent usage of the RIG were analysed.

Cytological sampling versus forceps biopsy during percutaneous transhepatic biliary drainage and analysis of factors predicting success.

Purpose: To assess the accuracy of cytological sampling and forceps biopsy in obstructing biliary lesions and to identify factors predictive of success.

Methods: Consecutive patients (n = 119) with suspected malignant inoperable obstructive jaundice treated with percutaneous transhepatic biliary drainage during 7 years were included (60 male; mean age 72.5 years).

Percutaneous transhepatic biliary drainage (PTBD) with or without stenting-complications, re-stent rate and a new risk stratification score.

Objectives: To review the success rate and number of complications in patients with obstructive jaundice treated with percutaneous transhepatic biliary drainage (PTBD), and to stratify the procedural risk of both PTBD and biliary stenting.

Subjects And Methods: 948 procedures performed in 704 consecutive patients with obstructive jaundice over a 7 year period were reviewed: 345 male; 359 females, mean age 70.1 years (range 48-96 years).

Chemotherapy plus percutaneous radiofrequency ablation in patients with inoperable colorectal liver metastases.

Aim: To access the efficacy of chemotherapy plus radiofrequency ablation (RFA) as one line of treatment in inoperable colorectal liver metastases.

Methods: Eligible patients were included in three Phase II studies. In the first study percutaneous RFA was used first followed by 6 cycles of 5-fluorouracil, leucovorin and irinotecan combination (FOLFIRI) (adjunctive chemotherapy trial).

Interventional radiology in the management of malignant biliary obstruction.

Malignant biliary obstruction is commonly due to pancreatic carcinoma, cholangiocarcinoma and metastatic disease which are often inoperable at presentation and carry a poor prognosis. Percutaneous biliary drainage and stenting provides a safe and effective method of palliation in such patients, thereby improving their quality of life. It may also be an adjunct to surgical management by improving hepatic and, indirectly, renal function before resection of the tumor.

Magnetic resonance imaging accuracy in assessing tumour down-staging following chemoradiation in rectal cancer.

Objective: Magnetic resonance imaging (MRI) is increasingly accepted as the radiological modality of choice staging rectal cancer but is subject to error. Neoadjuvant therapy is increasingly used in rectal cancer and MRI is used to stage response and occasionally plan surgery. We aim to assess the staging accuracy of MRI following chemoradiotherapy in rectal cancer.

Immediate and long-term CT appearances following radiofrequency ablation of renal tumours.

The incidence of renal cell carcinoma is increasing and image-guided radiofrequency ablation (RFA) is emerging as a safe and effective primary treatment. Therefore, it is essential for radiologists to appreciate the varied computed tomography (CT) imaging features following RFA. Prompt recognition of residual or recurrent tumour is crucial in facilitating timely re-treatment where necessary.

Long-term results of percutaneous radiofrequency ablation of unresectable colorectal hepatic metastases: final outcomes.

Introduction: Percutaneous radiofrequency ablation (PcRFA) provides alternative means of treating patients with unresectable colorectal liver metastases. We previously reported our initial experience in 30 patients treated with PcRFA. We present the final long-term results in these 30 patients.

Routine use of gastrograffin enema prior to the reversal of a loop ileostomy.

Background/aims: Anastomotic failure occurs in up to 10% of patients following anterior resection. Selective use of a loop ileostomy may reduce the septic consequences of anastomotic leak. The use of gastrograffin enema to confirm the anastomotic integrity prior to ileostomy closure is still controversial.

Computed tomography appearances of sclerosing encapsulating peritonitis.

Sclerosing encapsulating peritonitis (SEP) is a serious complication of peritoneal dialysis (PD) characterized by thickened peritoneal membranes, which lead to decreased ultra-filtration and intestinal obstruction. Its early clinical features are nonspecific, and it is often diagnosed late following laparotomy and peritoneal biopsy, when the patient develops small bowel obstruction, which can be a life-threatening complication. However, this is changing with increasing awareness of computed tomography (CT) findings in SEP.

Management of renal tumors by image-guided radiofrequency ablation: experience in 105 tumors.

Aims: In this article we present our experience with radiofrequency ablation (RFA) in the treatment of 105 renal tumors.

Materials And Methods: RFA was performed on 105 renal tumors in 97 patients, with a mean tumor size of 32 mm (11-68 mm). The mean patient age was 71.

Radiological recanalization of an occluded anterior resection anastomosis.

We present a case of occluded colorectal anastomosis following surgery for rectal tumor. Contrast enema and antegrade ileography confirmed occlusion by a thin membrane. This was thought amenable to needle puncture and placement of a temporary stent under fluoroscopy guidance, avoiding surgery and its associated morbidity.

Percutaneous radiofrequency ablation of colorectal hepatic metastases - initial experience. An adjunct technique to systemic chemotherapy for those with inoperable colorectal hepatic metastases.

Background And Aim: Most patients with hepatic metastases from colorectal carcinoma are unsuitable for resection. Radiofrequency ablation (RFA) has been applied to such lesions at laparotomy. This study aimed to evaluate the less invasive approach of percutaneous RFA.

Technical aspects and complications of laparoscopic banding for morbid obesity--a radiological perspective.

Morbid obesity is a significant clinical problem in the western world. Various surgical restrictive procedures have been described as an aid to weight reduction when conservative treatments fail. Adjustable laparoscopic gastric banding (LAPBAND) has been popularized as an effective, safe, minimally invasive, yet reversible technique for the treatment of morbid obesity.

Early experience with percutaneous radiofrequency ablation of small solid renal masses.

Objective: Incidental small renal-cell masses are often seen in elderly patients with significant comorbidity who are unfit to undergo major surgery. This study was conducted to determine the safety and efficacy of percutaneous imaging-guided radiofrequency ablation in the management of small solid renal masses, almost all of which are renal cell cancers.

Conclusion: Early experience suggests that radiofrequency ablation is a safe, well-tolerated, and minimally invasive therapy for patients with solid renal masses.

The role of Acucise endopyelotomy in the treatment of ureteropelvic junction obstruction.

Objective: Open surgical pyeloplasty has been the gold standard for the correction of ureteropelvic junction obstruction (UPJO). Endourological management of UPJO has gained increased acceptance, with reported success rates of 57-87%. It has been suggested that Acucise endopyelotomy (AE) should be the procedure of choice for patients with UPJO.

Testicular microlithiasis: prevalence and tumor risk in a population referred for scrotal sonography.
