High-resolution magnetic resonance imaging of the anorectal region without an endocoil
Abdominal Imaging, 1999 To evaluate the feasibility of a high-resolution magnetic resonance imaging (MRI) technique in detailed imaging of the anal sphincter and lower pelvic region without the use of an endoluminal coil.MRIs with an external phased array coil (T1- and T2-weighted turbo spin echo) were performed in 22 volunteers and 12 patients with an anal fistula, an anal ...

The Endocoil Stent for Malignant Biliary Obstruction
Gastrointestinal Endoscopy Clinics of North America, 1999The Endocoil (Instent, Inc., Eden Prairie, MN), first introduced in 1993, is a self-expandable nitinol stent made of a coil spring of nickel-titanium alloy. Advantages of the Endocoil in patients with malignant biliary obstruction were thought to include increased radial force with more rapid stricture dilation, inhibition of tumor ingrowth caused by ...

The Endocoil for Benign Biliary Obstruction
Gastrointestinal Endoscopy Clinics of North America, 1999This article evaluates the use of the Endocoil in patients with benign biliary obstruction. It contains detailed information regarding the practicalities of insertion and retrieval of the Endocoil stent and examines the evidence for its use in this group of patients. The author discusses complications and how to avoid them, and provides recommendations

TRUS and endocoil MRI in prostatic cancer
, 2002 Objective: Accurate staging of prostatic cancer is important for planning an optimal treatment, such as radical prostatectomy in clinical stage T2. About 40-50% of patients operated for cT2 disease show a pathological stage T3 disease. In a prospective study we analysed accuracy of TRUS and endocoil MRI in a group of patients before radical ...

Evaluation of dysfunction following reconstruction of an anorectal anomaly
Pediatric Surgery International, 2002 To evaluate the utility of anorectal manometry (ARM) and magnetic resonance imaging (MRI) with an endocoil in the assessment of dysfunction in children with repaired anorectal anomalies (ARA), 15 patients aged 1 to 15 years with repaired ARAs and chronic

Endoscopy, 1997 One of the major disadvantages of nitinol endocoil stents is said to be incomplete deployment leading to twisting and stent dysfunction. We report a patient with irresectable pancreatic head cancer where severe twisting of the nitinol stent occurred ...

The failure of external anal sphincter repair may relate to sphincter atrophy where muscle fibers are replaced by fat, seen on MRI due to the differing signals returned by fat and muscle tissue. Manometry, electrophysiology, and MRI with an endocoil were performed on 34 fecally incontinent patients with intact sphincters on endosonography.
