Filter by:Gallstones in the common bile duct (CBD) may be asymptomatic but may lead to complications such as acute cholangitis or acute pancreatitis. EST is widely used for the treatment of bile duct gallstones. Despite its efficacy and improvements over time, EST is still associated with complications such as hemorrhage, perforation, pancreatitis, and permanent loss of function of the sphincter of Oddi (SO). Permanent loss of SO function can cause duodenobiliary reflux, bacterial colonization of the biliary tract, gallstone recurrence, cholangitis, and liver abscess. Endoscopic papillary balloon dilation (EPBD) was first proposed in 1983 and it is now recognized as an alternative technique for the removal of CBD gallstones. The small balloon (diameter <8 mm) is less invasive, reduces the occurrence of adverse effects, and preserves the SO function, but it has limitations in the presence of CBD gallstones ≥10 mm in diameter. EST combined with endoscopic papillary large-balloon dilation (EPLBD) has been introduced for patients with large gallstone, but EPLBD widens the distal common bile duct and still may cause SO function damage, partially or completely. Repairing the ampulla of Vater and SO may reduce the long-term complication rates, especially gallstone recurrence. Unfortunately, no efficient strategy has been proposed. The present pilot study aimed to examine the feasibility and efficiency of an innovative strategy named endoclip papilloplasty to repair the damaged ampulla and recover SO function. The advantage of this device is that it can be rotated clockwise or counterclockwise by turning the handle until the correct position is achieved. Another advantage is if the clip is not in desired position, it may be re-opened and repositioned. Once satisfying clip positioning is achieved, the clip can be firmly attached to the tissue by pulling the slider back until tactile resistance is felt in the handle.Briefly, the operator assessed the patulous biliary opening and ductal axis, positioned and adjusted eachendoclip in order to close the patulous opening
Extended day surgery or 23 h surgery (23-hour surgery) is a surgical model where patients arrive to the hospital from home at the day of surgery, are operated and recover in a 23 h surgery unit. 23H surgery units are usually situated near postoperative recovery unit. THe 23 H surgical model was implemented in Kuopio University Hospital 2015 and between May 2017-May 2018 patients were recruited in the present prospective follow up cohort study. Patients were informed and they gave their informed consent. The patients were contacted two weeks after the study and details of their recovery were asked.
Laparoscopic cholecystectomy is currently the standard procedure for removing the gallbladder. This procedure usually requires the insertion of four trocars into the abdomen for passage of laparoscopic instruments; each trocar requires a small incision, which results in postoperative pain and scarring. There has recently been a tremendous surge in interest within the surgical community to further reduce the pain, invasiveness, and cosmesis of laparoscopic surgery. To achieve this goal, surgeons are either reducing the number of trocars placed through the abdominal wall or eliminating them completely The goal of this project is to evaluate the feasibility of performing transvaginal cholecystectomy while obtaining safe access under laparoscopic visualization. This has the potential to decrease postoperative pain, improve cosmesis, and lead to a shorter recovery following cholecystectomy.
The purpose of the present study was to evaluate the success of routine use of intraoperative cholangiography (IOC ) and to examine the factors that are hindering the performance of intraoperative c-arm cholangiography.
1. determine the most important factors which is responsible for the outcome post bile and gallstones spillage during laparoscopic cholecystectomy 2. the management of complications of bile and gallstones spillage
Objective. To measure the pressures of the common bile duct in patients with and without cholelithiasis and relating them to the presence of pancreatobiliary reflux. Summary Background Data. The reflux of pancreatic enzymes into the epithelium of the bile duct and mainly of the gallbladder is an abnormal phenomenon that plays a role in the lithogenesis and carcinogenesis of this epithelium. It has been suggested that the cause of this reflux is the dysfunction of the sphincter of Oddi. Because the pressure of the common bile duct depends on the pressures of the sphincter of Oddi, this dysfunction would be reflected in an increase in the pressure of the common bile duct in patients with cholelithiasis. Methods. A prospective case-control study was designed. The universe was constituted by a convenience sample in which all patients undergoing gastrectomy for gastric cancer during 30 months in our institution were included. The primary outcome measure was to establish differences between common bile duct pressures in patients with and without cholelithiasis. Results. Common bile duct pressures in patients with gallstones showed a significant elevation (Mean 16.9 mmHg) compared to those of patients without gallstones (Mean 3.3 mm Hg) (p<0.0001). These pressures correlated with the values of amylase and lipase in gallbladder bile; higher levels of these enzymes were found in patients with gallstones compared to patients without gallstones (p<0.0001). Conclusions. Common bile duct pressures in patients with cholelithiasis were significantly elevated above the parameters previously considered normal.
The objective of this clinical trial is to visualize the bile ducts by injecting a contrast that is only visible with infrared light. For this, we administrate an intravenous low dose of ICG before a cholecystectomy. During the intervention the tissue will be exposed to infrared light to visualize the bile ducts. This technique aims to increase safety in surgery to avoid damaging bile or vascular structures during gallbladder interventions.
Determine differences between lithogenic and non-lithogenic bile composition.
In this prospective study, the investigators assessed the utility of intermittent saline irrigation in reducing the recurrent rate of choledocholithiasis after the endoscopic extraction for common bile duct stones, and it does not increase the rate of procedure-related complications.
The objective of the trial was to explore the effect of different infusion volume on perioperative bladder and blood volume in patients undergoing daytime surgery assisted by bladder and vascular ultrasound and transthoracic echocardiography.
