133. Choice of sedation in endoscopic retrograde cholangiopancreatography: is monitored anesthesia care as safe as general anesthesia? A systematic review and meta-analysis.

Abstract

Background Monitored anesthesia care (MAC) and general anesthesia (GA) are the 2 most common methods of sedation used for endoscopic retrograde cholangiopancreatography (ERCP). We performed a systematic review and meta-analysis to compare the overall safety between MAC vs. GA in ERCP. Methods We conducted a comprehensive search of electronic databases to identify studies reporting the use of MAC or GA as a choice of sedation for ERCP. The primary outcome was to compare the overall rate of sedation-related adverse events in MAC vs. GA groups. The secondary endpoint was to investigate the total duration of the procedure, recovery time, ERCP cannulation rates, and conversion rate of MAC to GA. The meta-analysis was performed using a Der Simonian and Laird random-effects model. Results A total of 21 studies reporting on 11,592 patients were included. The overall sedationrelated side-effects were similar in the GA (12.76%, 95% confidence interval [CI] 5.80-21.73; I2=95%) and MAC (12.08%, 95%CI 5.38-20.89; I2=99%) groups (P=0.956). Hypoxia, arrhythmias, hypotension, aspiration and other sedation-related side-effects were similar between the 2 groups. The mean duration of the procedure was longer in the MAC group, but the mean recovery time was shorter. Significant heterogeneity was noted in our meta-analysis. Conclusions In our meta-analysis, the overall sedation-related side-effects were similar between the MAC and GA groups. MAC could be used as a safer alternative to GA when performing ERCP. However, large multicenter randomized control trials are needed to further validate our findings. [ABSTRACT FROM AUTHOR]

134. Percutaneous balloon valvuloplasty compared with open surgical commissurotomy for mitral stenosis

Author

Abstract

Percutaneous balloon valvuloplasty appears to be as effective as open surgical commissurotomy for patients with mitral stenosis. Mitral stenosis is the gradual narrowing of the mitral valve of the heart. The traditional surgical treatment is open commissurotomy, which allows the operating doctor to visually inspect the valve being operated on. Balloon valvuloplasty is a closed procedure that uses balloons attached to a catheter to widen narrowed mitral valves. Two groups of 30 patients with mitral stenosis were operated on with one of the two techniques. The average mitral valve area of both groups before surgery was 0.9 square centimeters (cm2). After surgery, the balloon valvuloplasty group's average mitral valve area was 2.1 cm2, compared to 2.0 cm2 in the open commissurotomy group. After three years the balloon valvuloplasty group's average mitral area was greater than the open commissurotomy group's. Balloon valvuloplasty is half as expensive as open commissurotomy.

Abstract

Abstract Background In brain tissues from multiple sclerosis (MS) patients, clusters of activated HLA-DR-expressing microglia, also referred to as preactive lesions, are located throughout the normal-appearing white matter. The aim of this study was to gain more insight into the frequency, distribution and cellular architecture of preactive lesions using a large cohort of well-characterized MS brain samples. Methods Here, we document the frequency of preactive lesions and their association with distinct white matter lesions in a cohort of 21 MS patients. Immunohistochemistry was used to gain further insight into the cellular and molecular composition of preactive lesions. Results Preactive lesions were observed in a majority of MS patients (67%) irrespective of disease duration, gender or subtype of disease. Microglial clusters were predominantly observed in the vicinity of active demyelinating lesions and are not associated with T cell infiltrates, axonal alterations, activated astrocytes or blood–brain barrier disruption. Microglia in preactive lesions consistently express interleukin-10 and TNF-α, but not interleukin-4, whereas matrix metalloproteases-2 and −9 are virtually absent in microglial nodules. Interestingly, key subunits of the free-radical-generating enzyme NADPH oxidase-2 were abundantly expressed in microglial clusters. Conclusions The high frequency of preactive lesions suggests that it is unlikely that most of them will progress into full-blown demyelinating lesions. Preactive lesions are not associated with blood–brain barrier disruption, suggesting that an intrinsic trigger of innate immune activation, rather than extrinsic factors crossing a damaged blood–brain barrier, induces the formation of clusters of activated microglia.

138. Use of Endoscopic Ultrasound in a Diagnostic Dilemma: Metastatic Breast Cancer to the Stomach

Abstract

A 55-year-old woman presented with persistent nausea, vomiting, and weight loss previously attributed to Ménétrier’s disease. On further workup, she was found to have metastatic lobular breast carcinoma causing gastric outlet obstruction, diagnosed by endoscopic ultrasound with fine needle aspiration after previous gastric mucosal biopsies were unremarkable. In most reported cases of gastric metastasis from breast cancer, a diagnosis was established by mucosal biopsy. This case is an important reminder that mucosal biopsies can be negative in about 20% of patients with gastric metastasis, which may lead to a delay in diagnosis and treatment. Gastroenterologists should be diligent in taking deeper biopsies if there is a suspicion for gastric metastasis.

Abstract

A 71-year-old male presented to our institution with cholestatic hepatitis after having recently undergone upper endoscopy for treatment of gastrointestinal bleeding. Further investigation with endoscopic retrograde cholangiopancreatography revealed a hemostatic clip on the ampulla of Vater. After initial attempts at cannulation of the common bile duct were unsuccessful, biliary decompression was achieved by use of needle-knife fistulotomy. A common bile duct stent was placed and the liver function tests improved prior to discharge.
