Performing an EUS prior to ERCP in the setting of a positive intraoperative cholangiogram will identify and risk stratify patients for the presence of CBD stones and strictures.
This study is designed to be a United States multicenter prospective randomized controlled non-inferiority evaluation of transgastric and transvaginal Natural Orifice Translumenal Endoscopic Surgery (NOTES) cholecystectomy compared to laparoscopic cholecystectomy in elective surgery patients. Up to 200 patients will be enrolled to obtain 70 NOTES cholecystectomies (35 transgastric and 35 transvaginal) and 70 laparoscopic cholecystectomies on a randomized basis. In order to evaluate the hypothesis that NOTES cholecystectomy has equivalent safety and efficacy to laparoscopic cholecystectomy, clinical and administrative outcomes will be measured.
Participation in this research study does not involve any procedures. Health preference will be ascertained through standard techniques including time-tradeoff, standard gamble, and rating scale to assess risks regarding potential complications specific to NOTES (Natural Orifice Translumenal Endoscopic Surgery)gallbladder removal.

This study proposes to evaluate the ability to reduce the size and number of laparoscopic incisions required to perform gall bladder removal by using flexible endoscopic instruments introduced through the mouth, into the stomach and through the stomach wall.
Subjects were patients of the five surgeons with Surgical Associates of Mansfield (SAM) who underwent an elective or urgent laparoscopic cholecystectomy; or elective or urgent laparoscopic or open hernia repair (inguinal, ventral, or umbilical); and who otherwise met the inclusion criteria. I
The purpose is to find out if intraoperative acupuncture performed by needling PC 6 and LI4 point bilaterally, and Yin Tang point will help reduce the incidence postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when added to a prophylactic regimen consisting of ondansetron and dexamethasone. The hypothesis is that the addition of this acupuncture treatment to ondansetron and dexamethasone given for prophylaxis will help reduce the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when compared to patients receiving ondansetron and dexamethasone without acupuncture.
The goal of this study is to evaluate the utility and efficacy of an artificial intelligence (AI) model at identifying structures and phases of surgery compared to traditional white light assessment by trained surgeons. Surgeons will perform the procedure in their standard practice, while the AI model analyzes data from the laparoscopic camera. Surgeons will be asked to audibly state when they identify structures and enter different phases of the surgical procedure. The AI will not alter the surgeon's view or be visible to the surgeon, and the surgeon will perform the procedure in the exact same fashion as they typically do.
This is a prospective single arm, single center study estimating percentage of successful critical anatomy recognition in laparoscopic cholecystectomy surgeries using SPY fluorescence imaging and ICG, with each surgery also providing a white light 360 degree images. The primary objective is to determine the percentage of successful critical anatomy recognition using intra-operative SPY fluorescence imaging and ICG: and to describe complications associated with intra-operative decision making in patients undergoing laparoscopic cholecystectomy.
The study aims to evaluate the short-term clinical outcomes after complex robotic-assisted and laparoscopic cholecystectomies.
The purpose of this study is to determine compliance with the Prisma Health-Upstate Laparoscopic Cholecystectomy Perioperative Protocol.
We believe that subtotal cholecystectomy is a safe alternative to total cholecystectomy when the complicated gallbladder is encountered, resulting in decreased or equivalent risk of bile duct injury, major vascular injury, postoperative hemorrhage, infectious complications, and mortality. Additionally, we hope to further elucidate the expected outcomes of the varying subtypes of subtotal cholecystectomy in order to determine the safest approach, assuring the lowest need for secondary intervention, recurrent biliary disease, or need for a completion cholecystectomy.
This post-market clinical study is designed to evaluate the effectiveness of the Ultravision™ System when compared to the Airseal® iFS within an approved indication for use, namely laparoscopic cholosystectomy.
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.
This research is being done to examine which minimally invasive surgical approach is associated with the best outcomes when performing cholecystectomy surgery: laparoscopic or robotic? Laparoscopic and robotic approaches are similar surgical procedures using small incisions. The laparoscopic approach is largely used for the removal of the gallbladder (cholecystectomy). At UIC, the investigators perform the majority of the gallbladder surgeries through the robotic approach and only a few using the laparoscopic approach. The robotic surgical tools allows the surgeon the same freedom of movement as a human wrist, while using a 3D camera view. The laparoscopic and robotic surgical approaches both represent minimally invasive surgery approach and are associated with less pain, faster recovery and better cosmetic outcomes when compared to traditional open surgery. It is not currently known which approach is better.
Comparing the use of surgical robotics during a Cholecystectomy, comparing different platforms and approaches (multi port verses single port).
The objective of this study is to compare transversus abdominis plane (TAP) blocks to local wound infiltration (LWI) in terms of postoperative pain control in pediatric patients undergoing elective laparoscopic cholecystectomy. Our hypothesis is that TAP blocks will be superior to LWI for postoperative pain control resulting in decreased use of opioid / narcotic pain medication and decreased pain scored in the immediate 24-hour postoperative period. The rationale is that determining the effect of analgesia in this pediatric population is important to optimize clinical care.
Laparoscopic cholecystectomy is associated with considerable postoperative pain and surgeon-administered local anesthetic infiltration is the standard practice for achieving post-operative analgesia. However, recent studies have shown that pediatric patients continue to experience significant pain during the first 24 hours. The investigators plan to conduct a prospective, double-blinded, randomized study where patients will be designated into either a test group receiving an ultrasound-guided transversus abdominis plane (TAP) and rectus sheath (RS) blocks with ropivacaine and peri-portal sterile saline or the control group that will receive ultrasound-guided TAP block with sterile saline and peri-portal infiltration of ropivacaine. The anesthesia team and surgical team will both be blinded as well as the research personal in the postoperative period. Patients age 5-17 and American Society of Anesthesiology status I and II undergoing laparoscopic cholecystectomy will be included. The study hypothesis is that ultrasound-guided peripheral nerve blocks, specifically single shot transversus abdominis plane and rectus sheath blocks, are superior to local wound infiltration during laparoscopic cholecystectomy for decreasing postoperative pain and pain related behavior and facilitating functional recovery.
This is a prospective, double-blinded, randomized controlled study comparing the efficacy of trans-incisional rectus sheath block to laparoscopic guided rectus sheath block for pediatric single-incision laparoscopic cholecystectomy (SILC). umbilical hernia repair in children. Patients aged 10-21 years old undergoing SILC for cholelithiasis, cholecystitis, or biliary dyskinesia will be screened for study inclusion. Eligible patients and their parents/guardians will be approached and, if agreeable, consented for the study pre-operatively. Patients will be randomized to receive either trans-incisional rectus sheath block or intra-operative rectus sheath block under direct laparoscopic visualization. Both will be done by the attending pediatric surgeon. The patient, patient guardians, select research team members, and Post anesthesia care unit (PACU) staff will be blinded to the method of analgesic administration.
Essential to laparoscopic operations is adequate visualization. Unfortunately there is no grading system to assess the degree or quality of visualization. The primary objective of the project is to develop a laparoscopic visualization scoring system. We also intend to investigate the effects of neuromuscular blockade agents on visualization.
The goal of this study is to challenge the existing clinical practice of employing laparoscopic cholecystectomy as the treatment for gallbladder dyskinesia by comparing it to a regimen of active non-surgical therapy.
The objective of this study is to determine if IV acetaminophen administered intraoperatively can decrease the dose of narcotics required for adequate pain control and shorten recovery time in the PACU specifically in obese patients at risk for obstructive sleep apnea.
