Olympus reviewed the following literature article: "factors affecting the yield of endoscopic transpapillary bile duct biopsy for the diagnosis of pancreatic head cancer" by hirokazu kimura, et al.The study was aimed to identify factors associated with a positive outcome using transpapillary biliary biopsy (tbb) for pancreatic head cancer (phc).Total 130 cases that underwent tbb for investigation of distal biliary stricture were included [62 cases of phc, 36 cases of distal biliary cancer (dbc), and 32 cases of benign biliary stricture (bbs)], and the factors affecting the diagnostic efficiency of tbb were determined using univariate and multivariate logistic analyses.The study reported that endoscopic biliary forceps biopsy showed a carcinoma component in 31 (50%) of 62 phc cases, 33 (91.7%) of 36 dbc cases, and none of the bpm cases.The cancer-positive rate for dbc was significantly higher than that for phc (p < 0.01).No complications other than three (one case (1.61%) of 62 phc and two cases (5.56%) of 36 dbc) cases of post-ercp pancreatitis were reported.The study concluded with the suggestion that phc with a high level of serum bilirubin (>10 mg/dl) and a high circumferential proportion of bile duct invasion (>2/3 judging by mdct) was a good indication for biliary biopsy.The authors reported: post-ercp pancreatitis - (3) : mild and improved in 2 days.The adverse events were submitted as follows: (b)(6): fb-39q.(b)(6): clevercut/kd-vc411q-0725.(b)(6): fb-44u.Upon follow up with the author, he stated: in rare cases, malfunctions with biopsy forceps were already reported to the olympus staff at our hospital each time.For example, the forceps did not spread well, and the wire was broken.The author did not specify which biopsy forceps did not spread well.This article includes additional reports as follows: (b)(6): fb-39q is for the forceps that did not spread well.(b)(6): fb-44u- is for the forceps that did not spread well.(b)(6): clevercut/kd-vc411q-0725 is for the broken wire.This report is 6 of 6 for (b)(6): clevercut/kd-vc411q-0725 is for the broken wire.
