BACKGROUND/AIMS The aim of this study was to evaluate the outcome of endoscopic dilation for benign anastomotic stricture after radical gastrectomy in gastric cancer patients. METHODS Gastric cancer patients who underwent endoscopic balloon dilation for benign anastomosis stricture after radical gastrectomy during a 6-year period were reviewed retrospectively. RESULTS Twenty-one patients de...

BACKGROUND To assess the short-term outcomes after endoscopic sphincterotomy (EST) plus endoscopic papillary balloon dilation (EPBD) versus EPBD alone and appropriate balloon dilation time in EPBD alone. MATERIALS AND METHODS A total of 413 patients with common bile duct stones (CBDSs) were included in the EST plus EPBD group and 84 were in the EPBD alone group. We retrospectively evaluated t...

A common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. Gastric injury has been observed in patients who ingested alkali. Gastric outlet obstruction (GOO) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion....

OBJECTIVES/HYPOTHESIS Although acquired nasopharyngeal stenosis (NPS) is frequently attributed to infectious and granulomatous processes, it can also occur secondary to external beam radiation therapy for head and neck cancer. NPS can be treated with local flaps, laser excision, nasal stenting, and combinations thereof. Unfortunately, the postoperative course is frequently complicated by scarri...

with a novel fine-gauge balloon catheter: one-step placement technique During endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), it is necessary to dilate the fistula [1]. Graded dilation with a 4-Fr cannula and 6and 7-Fr bougie dilators is relatively easily performed, and this stepwise procedure appears to be safe [2]. On the other hand, the use of a needle knife for fistula dilation ...

Here we investigated how a coating of intravascular balloon with paclitaxel (drug-coated balloon; DCB, Freeway™) impacted porcine peripheral artery vascular function and remodeling. Domestic swine (n = 54) underwent percutaneous overstretch balloon dilation of femoral and iliac arteries, controlled by angiography and optical coherence tomography (OCT). Paclitaxel tissue uptake was measured at 1...

BACKGROUND Experience of balloon dilation of peripheral pulmonary stenosis (PPS) in Williams syndrome (WS) is limited. METHODS AND RESULTS Catheterizations in all patients with WS undergoing therapy for PPS from 1984 to 1999 were reviewed. Criteria for successful dilation included an increase >50% in predilation diameter and a decrease >20% in ratio of right ventricular (RV) to aortic (Ao) sy...

BACKGROUND/AIMS We compared the long-term outcomes of balloon dilation versus botulinum toxin injection in Korean patients with primary achalasia and identified factors predicting remission. METHODS We included 73 patients with achalasia newly diagnosed between January 1988 and January 2011. We ultimately enrolled 37 of 55 patients with primary achalasia through telephone interviews, who were...

The proximal optimizing technique (POT) -proximal balloon edge dilation (PBED) sequence for side branch (SB) dilatation with cross-over single-stent implantation decreases both strut obstruction at the SB ostium and stent deformation main (MB).
