Endoscopical Dilation of Benign Esophageal Strictures

Dysphagia

Although balloon dilatation is the primary treatment for benign dysphagia, information about the optimal inflation time is lacking. The aim of the current pilot study was to compare 10 seconds inflation time, with 2 minutes inflation time, regarding the efficacy

Electrical Stimulation Over Acupuncture Points in Reduction of Rectal Discomfort Distension

Pain

Colonoscopy is a stressful and unpleasant procedure especially during the passage of the endoscope through angulations of colon. Electro-acupuncture is one of the alternative to reduce colorectal discomfort. However acupuncture is invasive. This present study explored the effectiveness of a non-invasive treatment modality, Transcutaneous Electrical Nerve Stimulation over Acupuncture points in reduction of colorectal discomfort during barostat-induced rectal distension.

Endoscopic Papillary Large Balloon Dilatation Versus Mechanical Lithotripsy for Large Stones

Common Bile Duct Stones

Endoscopic sphincterotomy (EST) combined with large balloon dilation (LBD) has been increasingly accepted as alternative method for removal of large bile duct stones. However, there were limited studies comparing the efficacy of EST in combined with LBD to EST with mechanical lithotripsy (ML). The purpose of this study to compare the efficacy and safety of combined EST- LBD versus EST-ML in the removal of very large bile duct stones.

Evaluation of the Metricath Gemini System, a Device Intended to Make Arterial Measurements and Perform...

Angioplasty

The purpose of the Metricath Gemini System is to pre-dilate the target treatment area, take arterial lumen measurements in a native section of artery or within the deployed stent and perform further dilation of the deployed stent if required. In this manner, the Metricath Gemini System can assist the Interventionalist by providing arterial measurements prior to stenting, performing pre-stenting angioplasty, taking within stent measurements to help determine if the stent is fully deployed, and by performing post-stenting dilations to further dilate the stent if required.

Addition of Buprenorphine to Paracervical Block for Pain Control During Osmotic Dilator Insertion...

Procedural PainBuprenorphine4 more

Cervical preparation with osmotic dilators is commonly used prior to dilation and evacuation (D&E) procedures to decrease the risk of complications. Women have described the pain of osmotic dilator insertion as moderate to severe yet there have been few studies aimed at addressing pain during and after osmotic dilator insertion. In addition to the discomfort during insertion, pain after osmotic dilator insertion peaks at 2 hours post-insertion with use of a lidocaine paracervical block. One randomized trial found that use of a paracervical block with 1% buffered lidocaine decreased pain with osmotic dilator insertion compared to a sham block. There are adjunct treatments to optimize analgesia with local anesthetics at a variety of anatomic locations. Buprenorphine, a partial mu-opioid receptor agonist, has been found to increase the quality of the anesthetic at the time of administration and increase the duration of nerve block analgesia at several anatomic sites, though has never been studied as an adjunct in a paracervical block. This has been used extensively in orthopedic surgery with significant prolongation of the local anesthetic effect by almost threefold in some studies. Primary Aim: To compare the mean pain score at the time of osmotic dilator insertion among women randomized to a 1% lidocaine and buprenorphine paracervical block compared to a 1% lidocaine paracervical block alone. Secondary Aim: To compare the mean pain score 2 hours after osmotic dilator insertion among women randomized to a lidocaine and buprenorphine paracervical block compared to a lidocaine paracervical block alone. The investigators hypothesize that in patients undergoing osmotic dilator insertion in preparation for dilation and evacuation, the addition of buprenorphine 0.15mg to a 1% lidocaine paracervical block will be associated with lower mean pain scores at time of osmotic dilator insertion compared to women who receive a 1% lidocaine paracervical block alone.
