Dilation Time in Endoscopic Papillary Balloon Dilation for Common Bile Duct Stones.

ABSTRACT:

Background

To assess the short-term outcomes after endoscopic sphincterotomy (EST) plus endoscopic papillary balloon dilation (EPBD) versus EPBD alone and appropriate balloon dilation time in EPBD alone.

Materials and methods

A total of 413 patients with common bile duct stones (CBDSs) were included in the EST plus EPBD group and 84 were in the EPBD alone group. We retrospectively evaluated the safety and efficacy between EST plus EPBD and EPBD alone group. The patients in EPBD alone group were assigned to dilation time ?5 minutes group (n=35) and time <5 minutes group (n=49). Further, we preliminarily discussed the influence of balloon dilation time on the procedure-related complications.

Results

Compared with EST plus EPBD, the patients in EPBD alone group were younger [56.6 (range: 18 to 95) vs. 65.1 (24 to 92) y; P=0.006], had smaller diameter of the largest stone [10.4 (range: 3 to 20) vs. 12.3 (5 to 30) mm; P<0.001] and were lesser frequently performed with jaundice [22 (26.2%) vs. 189 (45.8%); P=0.001]. The mean duration of postoperative hospital stay in EPBD alone group was significantly shorter than EST plus EPBD group [6.3 (range: 1 to 18) vs. 9.2 (1 to 44) d; P<0.001]. The patients in EPBD alone group had higher risk of post endoscopic retrograde cholangiopancreatography pancreatitis than EST plus EPBD group [11 (13.1%) vs. 22 (5.3%); P=0.009]. Patients in the dilation time <5 minutes group had higher risk to suffer from postoperative pancreatitis than the EST plus EPBD group [9 (18.4%) vs. 22 (5.3%); P=0.002], while patients in the dilation time ?5 minutes group had less procedure-related hemorrhage than the EST plus EPBD group [0 vs. 36 (8.7%); P=0.047].

Conclusion

Long balloon dilation time in EPBD alone is safe and effective in treating CBDSs.

Project description:Male Sprague-Dawley rats weighing 250-300 g were purchased from Japan SLC Co. (Shizuoka, Japan). The animals were housed under a daily controlled 12-h light and 12-h dark cycle at 23 °C with free access to rat chow (Japan SLC Co.) and water for 1 week prior to the experiments. Rats were laparotomized under ether anesthesia in each experiment, and the common bile duct of each rat was ligated between the liver hilus and small intestine. Control animals underwent a sham operation with exposure but without ligation of the common bile duct. After the CBDL or sham operation, animals were allowed access to food and water ad libitum. Groups of three rats were sacrificed under ether anesthesia at 1, 3 and 12 hr after the CBDL or sham operation. At the time of sacrifice, the right lateral liver lobe was removed and flash-frozen in liquid nitrogen and stored at -80 °C. Total RNA isolated from frozen livers using TRIzol reagent (Invitrogen Co., Carlsbad, CA) was mixed to minimize variation among animals. Poly(A) RNA was purified using Oligotex-dT30 (Takara Shuzo Co., Ltd., Kyoto, Japan) in accordance with manufacturer’s instructions. Fluorescence-labeled probes were prepared by reverse transcription using a superscript II reverse transcriptase (Invitrogen Co.) and cyanine-3- and cyanine-5-dUTP (Perkin-Elmer Inc., Wellesley, MA). Poly(A) RNAs derived from rats that has undergone CBDL and from those that has undergone a sham operation were labeled with cyanine-3 and cyanine-5, respectively, and vise varsa. Fluorescence-labeled probes were purified using a MinElute PCR Products Purification Kit (Quiagen GmbH, Hilden, Germany) in accordance with manufacturer’s instructions. Each purified probe was suspended in hybridization buffer containing 1.6 mg/mL poly(A) (Roche Diagnostics, Basel, Switzerland) and yeast tRNA (Roche Diagnostics), 0.67 mg/mL herring sperm, 16% 20 x SSC and 0.3% SDS and applied to a cDNA microarray containing 1,800 rat genes on a slide glass (Asahi Technoglass Co., Tokyo, Japan). Three house-keeping genes (GAPDH, HPRT and b-actin) and rat unrelated traits (Lambda DNA) were also spotted on the slide as internal positive and negative controls, respectively. Hybridization was carried out twice to eliminate any dye bias. In one experiment, duplicate slides were hybridized with probes derived from CBDL and control rats that had been labeld with cyanine-3 and cyanine-5, respectively. In a replicate experiment, other duplicate slides were hybridized with probes derived from CBDL rats and control rats that had been labeled with cyanine-5 and cyanine-3, respectively (color swap). Then, the slides were cover-slipped and incubated in a sealed chamber (Asahi Technoglass Co.) for 16 hrs under a humidified (65 °C) condition. After being washed in low-stringency buffer (2 x SSC and 0.1% SDS), high-stringency buffer (0.2 x SSC and 0.1% SDS) and 0.2 x SSC and then rinsing with 99.5% ethanol, the slide was dried by centrifugation at low speed and used for scanning. Fluorescence was scanned by using a ScanArray 4000 (Packard BioChip Technologies, Billerica, MA) and quantified by using QuantArray Software (Packard BioChip Technologies, Billerica, MA).
