Endoscopic Management as a Viable Therapy for Pancreaticopleural and Pancreaticopericardial Fistulas.

Pancreatic fistulas are rare complications of chronic pancreatitis, typically caused when disruption of the pancreatic duct causes leakage of pancreatic fluid that erodes through neighboring organs and structures. Pancreatic fistulas to the pericardium and pleural spaces are extremely rare, and cases of multiple fistulas tracking from the pancreas have not been reported before. Management of these fluid collections is challenging with no consensus described in the current literature. We report a case of a patient with concurrent pancreaticopericardial and pancreaticopleural fistulas who improved with endoscopic management.

Management of microscopic colitis: challenges and solutions.

Microscopic colitis (MC) is a chronic inflammatory bowel disease characterized by nonbloody diarrhea in the setting of normal appearing colonic mucosa. MC has two main subtypes based on histopathologic features, collagenous colitis and lymphocytic colitis. Management of both subtypes is the same, with treatment goal of reducing the number of bowel movements and improving consistency. First-line treatment involves counseling the patient about decreasing their risk factors, like discontinuing smoking and avoiding medications with suspected association such as NSAIDs, proton pump inhibitor, ranitidine, and sertraline. Starting loperamide for immediate symptomatic relief is used as an adjunct to therapy with glucocorticoids. Budesonide is considered first-line treatment for MC given its favorable side effect profile and good efficacy, though relapse rates are high. Systemic glucocorticoids should be reserved to patients unable to take budesonide. In glucocorticoid refractory disease, medications that have been tried include cholestyramine, bismuth salicylate, antibiotics, probiotics, aminosalicylates, immunomodulators, and anti-tumor necrosis factor-alpha inhibitors. More research is needed for the creation of a systematic stepwise approach for relapsing and refractory disease.

Minimizing Radiation Exposure During ERCP by Avoiding Live or Continuous Fluoroscopy.

GOALS: The aim of this study was to assess the cumulative radiation exposure incurred by patients when using single-frame fluoroscopy. BACKGROUND: Single-frame fluoroscopy is a technique that can be used instead of pulsed fluoroscopy or continuous live fluoroscopy to minimize radiation exposure during endoscopic retrograde cholangiopancreatography (ERCP). STUDY: We retrospectively reviewed ERCPs performed at our academic medical center. We recorded fluoroscopy time (FT, minutes), total radiation dose (mGy), dose area product (DAP, Gy cm²), and effective dose (ED, mSv). ERCP degree of difficulty was graded based on procedure complexity level. RESULTS: There were 400 ERCP procedures performed on 210 patients, 32 ERCPs were unsuccessful. The mean FT for all procedures was 1.57 minutes (median, 1.2 min); the mean FT for complexity score 1 procedures (0.78 min) was significantly shorter than for all other procedures (P<0.0001). The mean total radiation dose delivered for all procedures was 23.02 mGy (median, 14.95 mGy). The total radiation dose for complexity score 1 procedures (13.15 mGy) was significantly lower than for all other complexity scores (P<0.0001). The mean total DAP was 3.62 Gy cm² and the mean ED was 0.94 mSv. Procedure complexity score 1 DAP (2.1 Gy cm²) and ED (0.55 mSv) were significantly lower than for all other procedures (P<0.0001 for both). There was no statistically significant difference in these parameters when comparing successful and unsuccessful procedures. CONCLUSIONS: Successful ERCP can be performed using single-frame fluoroscopy only. Our results demonstrate lower radiation exposure using this technique than what is reported in the literature.
