Pancreaticobiliary Reflux in Patients Without Cholelithiasis

Pancreaticobiliary Reflux

Pancreaticobiliary reflux has been found in patients with cholelithiasis and gallbladder cancer associated with normal pancreaticobiliary union. However, the presence of pancreaticobiliary reflux has not been studied in patients without gallstones (healthy gallbladders). The authors believe that pancreaticobiliary reflux might be a normal phenomenon in patients with and without gallstones, although in patients with cholelithiasis it might constitute a pathological condition associated with dismotility of the biliary tree and the sphincter of Oddi.

Comparing Epidural Versus General Anesthesia for LESS Cholecystectomies

Cholelithiasis

This study is a prospective, comparative, controlled, blinded study that will enroll a total of 70 adults that will undergo elective laparoendoscopic single-site incision gallbladder removal. The objective of this study is to compare Epidural versus General Anesthesia for postoperative pain, length of hospital stay, outcomes, and cost of post-cholecystectomy patients.

Single Incision Laparoscopic Cholecystectomy Using a Flexible Endoscope and Ethicon Manually Articulating...

CholelithiasisPain

The aim of this study is to improve the technique of laparoscopic cholecystectomy by using a flexible endoscope passed through a single umbilical skin incision, as previously reported, now with the use of Manually Articulating Devices (Ethicon Endo-Surgery, Inc.) through the endoscope.

The Cholelithiasis in Adults With Short Bowel Syndrome

Short Bowel Syndrome

Short-term studies have shown that patients with short bowel syndrome (SBS) often develop cholestasis or cholelithiasis. In this retrospective cohort study, we aimed to define the incidence, risk factors, and clinical consequences of cholelithiasis in adults with SBS over an extended time period.

Accuracy of Surgeon-performed Ultrasound in Detecting Gallstones - a Validation Study

Gallstones

Aims: To prospectively investigate the accuracy of surgeon-performed ultrasound for the detection of gallstones. Methods: 179 adult patients, with an acute or elective referral for an abdominal ultrasound examination, were examined with a right upper quadrant ultrasound scan by a radiologist as well as surgeon. The surgeons had undergone a four-week long education in ultrasound before participating in the study. Ultrasound findings of the surgeon were compared to those of the radiologist, using radiologist-performed ultrasound as reference standard.

Risk of Umbilical Trocar-site Hernia After SILC Cholecystectomy Versus Conventional Cholecystectomy...

CholecystolithiasisIncisional Hernia

Background Laparoscopic cholecystectomy is a very common procedure. Postoperative pain, especially around the umbilical port is dominating the first postoperative week. Single Incision Laparoscopic cholecystectomy (SILC) has been proposed to diminish postoperative incisional pain and improve cosmetic results, but results are not convincing and the risk of formation of an umbilical trocar-site hernia is not properly investigated. This study aimed to investigate the risk of umbilical trocar-site hernia formation after SILC vs. conventional 4-port laparoscopic cholesystectomy. Methods This is a cohort registry study with prospective questionnaire and clinical follow-up on 239 patients having a SILC from 1/1 2009 to 1/6 2011 vs. 478 mathed patients having a conventional laparoscopic cholecystectomy (consecutively from one month before and after SILC. They are matched for age, gender, date of operation, and surgeons skills (database from intraoperatively registered data). Primary endpoint is umbilical trocar-site hernia formation (operation for a umbilical hernia or clinical hernia). The H0 hypothesis is that there is not difference between SILC and conventional. Exclusion criteria are: death, operation for acute cholecystitis. The included patients will be sent a questionnaire asking for operation for a hernia in the area, suspicion of a hernia, and perioperative data that we do not have in the database. Futhermore those patients who suspect a hernia will be invited to aclinical exam by a medic to state the diagnosis. Furthermore we patients are asked to report if they have chronic pain and/or discomfort.

Laparoscopic Versus Transabdominal Ultrasound in Morbidly Obese Patients

CholelithiasisUltrasonography1 more

The objective of this study is to prospectively compare laparoscopic ultrasound to transabdominal ultrasound for the detection of gallbladder pathology in obese patients presenting for laparoscopic gastric bypass. We hypothesize that laparoscopic ultrasound will be more sensitive and specific for cholelithiasis than transabdominal ultrasound in morbidly obese patients.
