A Complete Pancreatico-Biliary Exploration Performed With A New Slim Linear Echoendoscope

Aims To compare the maneuverability and image quality of a newly developed slim linear echoendoscope with the slim standard in the evaluation of bilio-pancreatic diseases.

Methods Prospective, cross-sectional, observational study. All patients submitted to an EUS for the evaluation of bilio-pancreatic diseases were evaluated and those cases performed with the slim echoendoscopes were finally included in the study. The new slim EG-34J10 echoendoscope and the standard slim EG-3270UK echoendoscope [Pentax-Medical] were used in combination with the ARIETTA-V70 ultrasound console (Hitachi). Table shows the differences between both echoendoscopes. Maneuverability during esophageal intubation, passage through the pylorus, and access to the second portion of duodenum (D2) (scored from 0 to 3) were evaluated. The image quality was analyzed in the standard stations (esophagus, stomach and duodenum) (scored from 0 to 3). A descriptive analysis was performed, showing results as mean and standard deviation. Data were compared by Chi-square.

Results 537 EUS procedures were performed for the evaluation of bilio-pancreatic diseases, 128 (23.8 %) with the new EG-34J10, and 353 (65.7 %) with the EG-3270UK, which were finally included in the study. Mean age was 63 years (range 22-91, 272 women). A complete bilio-pancreatic exploration was possible in all cases (100 %). In terms of maneuverability, the new 34J10 presented a better esophageal intubation (2.9±0.2 vs 2.5±0.4; p < 0.05) and access to D2 (2.9±0.2 vs 2.4±0.4; p < 0.05), without differences in passage through the pylorus. On image quality, the 34J10 behaved better in duodenal stations (2.9±0.3 vs 2.7±0.4; p < 0.05), with no differences in esophageal nor gastric stations. There were no complications related to the procedure echoendoscopy in the study period.

Conclusions The new slim linear echoendoscope appears to have better maneuverability and improved image quality compared to the standard slim scope. A complete bilio-pancreatic examination can be performed safely and efficiently with both slim echendoscopes.
