High values on MELD are associated with EV and thrombocytopenia, with varices which need prophylactic therapy. As a result of their low sensitivity and specificity, it is suggested to maintain the recommendation of upper gastrointestinal endoscopy for all patients with cirhosis.
Background: Pancreatic pseudocyst endoscopic drainage
has been described as a good treatment option,
with morbidity and mortality rates that are lower
than surgery. The aim of our study is to describe the
efficacy of different forms of endoscopic drainage
and estimate pseudocyst recurrence rate after short
follow up period.
Patients and Methods: We studied 30 patients with
pancreatic pseudocyst that presented some indication
for treatment: persistent abdominal pain, infection
or cholestasis. Clinical evaluation was performed
with a pain scale, 0 meaning absence of pain
and 4 meaning continuous pain. Pseudocysts were
first evaluated by abdominal CT scan, and after
endoscopic retrograde pancreatography the patients
were treated by transpapillary or transmural (cystduodenostomy
or cystgastrostomy) drainage. Pseudocyst
resolution was documented by serial CT
scans.
Results: 25/30 patients could be treated. Drainage
was successful in 21 (70% in an ‘intention to treat’
basis). After a mean follow-up of 42±35.82 weeks,
there was only 1 (4.2%) recurrence. A total of 6 complications
occurred in 37 procedures (16.2%), and all
but 2 were managed clinically and/or endoscopically:
there was no mortality related to the procedure.
Patients submitted to combined drainage
needed more procedures than the other groups.
There was no difference in the efficacy when we
compared the three different drainage methods.
Conclusions: We concluded that pancreatic pseudocyst
endoscopic drainage is possible in most
patients, with high success rate and low morbidity.
Helicobacter pylori (HP) infection is endemic worldwide. The proposed treatment is expensive and there are few reports regarding reinfection rates in Brazil. The aim of this study was to compare the eradication rates obtained with two therapeutic options and to evaluate reinfection one year after treatment. This was a prospective randomized trial with 55 patients. Thirty-nine patients had active duodenal ulcer (DU) and 16 non-ulcer dyspepsia (NUD), and all tested positive for HP. Diagnosis was based on at least two positive tests: ultrarapid urease test, histology and/or culture. Patients were randomized to two groups: group OMC treated with 40 mg omeprazole (once a day), 500 mg metronidazole and 250 mg clarithromycin (twice daily) for 7 days, or group NA treated with 300 mg nizatidine (once a day) and 1000 mg amoxicillin (twice daily) for 14 days. Those patients in whom HP was eradicated were followed up for one year to evaluate reinfection. Twenty-five patients were randomized for OMC and 30 for NA. HP eradication occurred in 20/25 patients (80%) treated with OMC and 13/30 (43%) treated with NA (P = 0.01). After reallocation because of initial treatment failure, the overall eradication rate was 44/51 patients (86%). After an average follow-up of one year, we evaluated 34 patients (23 with DU and 11 with NUD). Reinfection occurred in 3/34 patients (7.6%). We conclude that OMC is effective for HP eradication, and that NA should not be used. Reinfection occurs in 7.6% of the patients in the first year after eradication.
According to the WHO, 16-18 million people in Central and South America are infected by Trypanosoma cruzi. Chagasic achalasia affects between 7.1% and 10.6% of the population. The aim of this study was to evaluate the effects of Botox injections in the clinical response and esophageal function of patients with dysphagia due to chagasic achalasia. In total, 24 symptomatic patients with chagasic achalasia were randomly chosen to receive Botulinum Toxin (BT) or saline injected by endoscopy in the lower esophageal sphincter (LES). Patients were monitored with a clinical score of dysphagia and an objective assessment (esophagograms, scintillography, manometry, and nutritional assessment) for a period of 6 months. Clinical improvement of dysphagia was statistically significant (P < 0.001) in patients receiving BT when compared with the placebo. There was no significant difference in the placebo group regarding clinical score, LES basal pressure and esophageal emptying time. Esophageal emptying time in the toxin group was significantly lower than in the placebo (P=0.04) after 90 days. There were non-significant increases in esophageal emptying of 25.36% and 17.39%, respectively, at 90 and 180 days, in the BT group (P=0.266). Gender, age, and baseline LES pressure did not influence the response to BT. Our data strongly suggests that intrasphincteric injection of BT in LES is clinically effective in the treatment of chagasic achalasia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
