BACKGROUND:

Gallbladder polyps are becoming a common finding in ultrasound. The management has to consider the potential risk of malignant lesions.

AIMS:

The aim of this study was to analyze the ultrasound findings in patients undergoing cholecystectomy due to gallbladder polyps and compare them for histopathological findings (HPs).

METHODS:

Patients with an ultrasonographic diagnosis of gallbladder polyp and who underwent cholecystectomy from 2007 to 2020 were included in the study.

RESULTS:

A total of 447 patients were included, of whom 58% were women. The mean age was 45±12 years. The mean size of polyps in US was 7.9±3.6 mm. Notably, 9% of polyps were greater than 10 mm, and single polyps were significantly larger than the multiple ones (p=0.003). Histopathological findings confirmed the presence of polyps in 88.4%, with a mean size of 4.8±3.4 mm. In all, 16 cases were neoplastic polyps (4.1%), 4 of them being malignancies, and all were single and larger than 10 mm. We found a significant correlation between ultrasound and histopathological findings polyp size determination (r=0.44; p<0.001). The Bland-Altman analysis obtained an overestimation of the US size of 3.26 mm. The receiver operating characteristic (ROC) curve analysis between both measures obtained an area under the receiver operating characteristic curve (AUC) of 0.77 (95%CI 0.74–0.81). Ultrasound polyps size larger than 10 mm had an odds ratio (OR) of 8.147 (95%CI 2.56–23.40) for the presence of adenoma and malignancy, with a likelihood ratio of 2.78.

CONCLUSIONS:

There is a positive correlation and appropriate diagnostic accuracy between ultrasound size of gallbladder polyps compared to histopathological records, with a trend to overestimate the size by about 3 mm. Neoplastic polyps are uncommon, and it correlates with size. Polyps larger than 10 mm were associated with adenoma and malignancy.

Background:

The pyogenic liver abscess has an incidence of 1.1/1,000 habitants. Mortality can reach 100%. The use of less invasive procedures diminish morbidity and hospital stay.

Aim:

Identify risk factors in patients who underwent percutaneous drainage guided by ultrasound as treatment.

Method:

Were analyzed 10 patients submitted to the method. Epidemiological characteristics, laboratory markers and imaging exams (ultrasound and CT) were evaluated.

Results:

The majority of the patients were men with mean age of 50 years old. Liver disease, alcoholism and biliary tract disease were the most common prodromes. Abdominal pain (90%), fever (70%) and jaundice (40%) were the most common clinical manifestations. Mortality of 20% was observed in this series. Hypoalbuminemia and days of hospitalization had a statistically significant positive association with death.

Conclusion:

The pyogenic liver abscess has subacute evolution which makes the diagnosis difficult. Image exams have high sensitivity in diagnosis, particularly computed tomography. Percutaneous drainage associated with antibiotic therapy is safe and effective therapeutic resource.

Background:

Laparoscopic cholecystectomy is widely used for cholelithiasis. Abdominal ultrasonography often precedes this operation and can prove diagnosis, as well as helps in showing possible complications during the perioperative period.

Aim:

Evaluate the description of variables of gallbladder and bile ducts present in reports of preoperative abdominal ultrasonography in cholelithiasis comparing with surgical findings.

Methods:

Were studied 91 patients who underwent elective laparoscopic cholecystectomy with previous abdominal ultrasonography. Variables such as identification and amount of gallstones involved were evaluated, both in preoperative ultrasonography and during surgery to evaluate sensitivity, specificity, concordance and positive and negative predictive values.

Results:

The reports did not mention diameter of vesicular light (98.9%), organ distension (62.6%), gallstone sizes (58.2%), wall thickness (41.8%) and evaluation of the common bile duct (39.6%). Ultrasound had high values for sensitivity, consistency and positive predictive value for identifying the presence/absence of gallstones: 98.8%, 96.7% and 97.8% respectively. As for the amount of stones, ultrasonography showed agreement in 82.7%, negative predictive value in 89.1% and specificity in 87.7%, with lower values for sensitivity (68.2%) and positive predictive value (65.2%).

Conclusions:

The ultrasound reports were flawed in standardization. Significant percentage of them did not have variables that could predict perioperative complications and surgical conversion.

INTRODUCTION

Acute pancreatitis is an inflammatory condition of the pancreas which can lead to morbidity. Formation of pancreatic pseudocyst is one of the well-known complication. While small pseudocyts are asymptomatic, large ones can become symptomatic and cause several complications including infection, rupture, bleeding, biliary complications and portal hypertension1,2.

Various interventions are available for the management of symptomatic pancreatic pseudocysts. Endoscopic ultrasound (EUS) guided cystogastrostomy is a choice for treatment of large pseudocyts, witch bulge into gastric lumen2,3. In this paper we present a case of large sized who was managed with argon plasma coagulation probe and without endoscopic ultrasonography.
