Bleeding as a complication of endoscopic sphincterotomy is influenced by several factors.
Dr Perini and colleagues from Canada undertook a study in order to compare rates of bleeding after sphincterotomy performed with two different electrosurgical current generators (Valleylab SSE2L and ERBE ICC200).
The research team analyzed a total of 6179 consecutive reports of ERCP.
The team compared the frequency of endoscopically and clinically evident bleeding after sphincterotomy when using the Valleylab SSE2L generator (from 02.94 – 11.97) and the ERBE ICC200 generator (from 12.97 – 09.00).
The researchers assessed relevant risk factors by univariate analysis and they included significant predictors in a multiple logistic regression model.
|Endoscopically observed bleeding occurred in 6% in the ValleyLab group and 1% in the ERBE group|
Surgeons performed a total of 2711 sphincterotomies in 2309 patients (1749 biliary, 962 pancreatic).
The researchers noted that endoscopically observed bleeding occurred in 68 patients (6%) in the ValleyLab group and 13 (1%) in the ERBE group.
The research team found that the ValleyLab generator was independently associated with an increase in endoscopically observed bleeding.
The researchers noted that there was no significant difference in clinically evident bleeding between the two groups.
Dr Perini concluded, "Use of the microprocessor-controlled ERBE electrosurgical generator for endoscopic sphincterotomy was associated with a significantly lower frequency of endoscopically observed bleeding but not clinically evident bleeding."
