OAC/OAF should be managed promptly by creating a barrier between oral cavity and maxillary sinus to prevent maxillary sinusitis. Treatment modalities to repair the oro-antral defects include local or free soft tissue flaps, with or without autografts or alloplastic materials.

2019年4月6日 · The aim of this study is to evaluate the appropriateness of OAC in CRC screening and polyp surveillance by comparing to procedures requested by gastroenterologists or non-open access colonoscopy. As secondary outcomes, we compared the quality of bowel preparation and adenoma detection rate (ADR) between OAC and NOAC.

Aims: The aim of this study is to evaluate the appropriateness of OAC in CRC screening and polyp surveillance by comparing to procedures ordered by gastroenterologists (NOAC). As secondary outcomes, we compared the quality of bowel preparation and adenoma detection rate (ADR) between OAC and NOAC.

2016年8月1日 · OAC is a method to allow patients to undergo endoscopy without prior evaluation by a gastroenterologist. We conducted a cross-sectional study to evaluate the indications and outcomes among patients scheduled for OAC or traditional colonoscopy at …

2021年2月8日 · The GP may prescribe an open-access colonoscopy (OAC) whereby the colonoscopy is performed without a prior office visit with a gastroenterologist . OAC theoretically should facilitate access to an endoscopic procedure bypassing unnecessary visit, reducing the costs, and increase the number of subjects who undergo screening colonoscopy .

2024年7月12日 · Polyps in the colon and rectum (together called colorectal polyps) are common in people over age 50. They are usually noncancerous, but certain characteristics can increase the likelihood of a polyp becoming cancerous. The risk of a …

In this study, we analyzed inflammatory cells in nasal polyp tissue of 65 CRSwNP patients after FESS surgery and determined aspirin hypersensitivity and contributing factors. OAC was performed 2 months after surgery to confirm AERD.

A high proportion of GIB caused by colonic polyps and colorectal cancer among OAC patients indicates that OACs treatment may facilitate cancer diagnosis. The low proportion of ischemic colitis among those on OACs suggests that OACs provide a …

OAC and GOJ-AC are often found in advanced stages as polypoid/fungating, ulcerated or diffusely invasive lesions leading to strictures. Early stage cancers may be found during endoscopic surveillance and appear as slightly elevated, flat …

2022年8月1日 · The oro-antral communication (OAC) is a pathological opening between the maxillary sinus and the oral cavity. When it does not close spontaneously or if it is not treated, it remains permeable and epithelializes to develop into an oro-antral fistula (OAF) and can cause maxillary sinusitis.
