Effect of Povidone-iodine Washing of Gastrointestinal Mucosa or Taking Proton Pump Inhibitors on Bacteremia after Endoscopic Ultrasonography-guided Fine Needle Aspiration

Incidence of Bacteremia Consequent to Different Endoscopic Procedures in Dogs: A Preliminary Study

Endoscopic procedures are widely used in veterinary medicine, and their role in producing transient bacteremia is debatable. The growing issue of antibiotic resistance requires the correct use of antibiotics, avoiding their administration when not strictly necessary. Studies highlighting post-endoscopy bacteremia in veterinary medicine are extremely rare and often involve very few animals. This study describes the results from 74 owned dogs, brought to the Veterinary Teaching Hospital of the Department of Veterinary Medical Science of the University of Bologna, for the purpose of undergoing an endoscopic procedure. Two blood samples were taken from each dog, one before and one after the procedure, in order to assess the incidence of bacteremia linked to endoscopic procedures. Eight dogs were tested positive at the second blood culture with an Incidence Risk (IR) of 10.8%. No statistical differences were found by comparing positive and negative blood cultures with respect to sex, age, weight and anesthesia duration. In addition, no difference was found between airway and digestive tract procedures. The present findings showed that the probability of developing bacteremia after an endoscopic procedure was quite low, and additional studies confirming this are certainly recommended as well as the evaluation of categories of patients potentially considered at risk.

Endoscopic removal of symptomatic gastric heterotopic pancreas: a report of nine cases

AIMS

The aim of this study was to evaluate the efficacy and safety of endoscopic removal of symptomatic gastric heterotopic pancreas (HP).

PATIENTS AND METHODS

From January 2010 to December 2011, 9 patients with suspected symptomatic HP were enrolled in the study. Endoscopic ultrasonography was performed to clarify the HP tissue location and to choose the endoscopic resection method. Endoscopic mucosal resection or endoscopic submucosal dissection was performed to remove the HP tissue. Symptoms in the enrolled patients were assessed before and after endoscopic removal of the HP tissue. Tumor pathology and complications were recorded after the treatment. A standard follow-up was scheduled at 1 week and 2 months after treatment.

RESULTS

Removal of suspected HP with endoscopic mucosal resection or endoscopic submucosal dissection was successful in all 9 cases. Abdominal pain, leukocytosis, and bleeding occurred in 6 patients, 2 patients, and 1 patient, respectively, after treatment and were relieved by symptomatic treatment. There were no other unpredictable complications. The symptoms related to HP, including epigastric pain, bloating, and postprandial fullness, were relieved significantly after the treatment. During follow-up, there was no recurrence of HP in any patient.

CONCLUSIONS

Endoscopic removal appears to be a safe and effective method to treat gastric lesions suspected to be HP with symptoms. The symptoms, such as epigastric pain, bloating, and postprandial fullness were well resolved after endoscopic treatment.

Combined EUS-Guided Abdominal Cavity Drainage and Cystogastrostomy for the Ruptured Pancreatic Pseudocyst

Background. Endoscopic-Ultrasonography- (EUS-) guided puncture and drainage of pancreatic pseudocyst is currently one of the most widely accepted nonsurgical treatments. To date, this technique has only been used for pancreatic pseudocysts adhesive to the gastric wall. This study introduces the technique of EUS-guided pseudocyst drainage and additional EUS-guided peritoneal drainage for the ruptured pseudocyst. Methods. Transmural puncture and drainage of the cyst were performed with a 19 G needle, cystotome, and 10 Fr endoprosthesis. Intraperitoneal drainage was performed with a nasobiliary catheter when rupture of pseudocyst occurred. The entire procedure was guided by the echoendoscope. Results. A total of 21 patients, 8 men and 13 women, with a mean age of 36 years, were included in this prospective study. All of the pseudocysts were successfully drained by EUS. Peritoneal drainage was uneventfully performed in 4 patients. There were no severe complications. Complete pseudocyst resolution was established in all patients. Conclusion. The technique of EUS-guided transmural puncture and drainage, when combined with abdominal cavity drainage by a nasobiliary catheter, allows successful endoscopic management of pancreatic pseudocysts without adherence to gastric wall.
