113 Clinical Trials for Various Conditions
This research study is testing whether the local anesthetic lidocaine is as effective as ropivacaine for post-operative pain control in continuous thoracic paravertebral nerve blocks. Ropivacaine and Lidocaine are FDA-approved drugs that has been successfully used in this hospital for post-operative pain control for the past few years, thus has become the standard drugs used for this nerve block. Lidocaine has numerous potential advantages over ropivacaine, such as faster onset of action, better safety profile and greater anti-inflammatory action. Catheters placed near both sides of a patient's spine for postoperative pain control are called thoracic paravertebral nerve blocks and are a part of routine care. Through those catheters, a "numbing" medication, or local anesthetic, to block the transmission of pain from the surgical incision to the spinal cord, thus reducing pain. The research part of the study is whether subjects will receive either the local anesthetic lidocaine or ropivacaine. The goal of this study is to determine whether the lidocaine controls pain better and facilitates a faster recovery after abdominal surgery than ropivacaine. In this research study, the investigators will compare patient-reported pain scores, any additional pain medication requirements for adequate pain control, time it takes for bowel function to return to normal following surgery, as well as the incidence of any side effects, such as numbness and weakness, subjects may experience between those receiving lidocaine versus those receiving ropivacaine. The investigators will screen 100 patients and enroll 60 subjects into this study.
Liberal intravenous fluid resuscitation during open abdominal surgery may predispose the patients to multiorgan dysfunction, prolong hospital stay and increase postoperative morbidity. The main aim of the study is to assess the safety and feasibility of restricted fluid regimen in open abdominal bowel surgery.
The purpose of this study is to evaluate the safety and efficacy of LB1148 in subjects undergoing planned bowel resection.
The purpose of this study is to establish preliminary evidence of the efficacy, safety, and tolerability of LB1148 for the treatment of post-operative ileus and intra-abdominal adhesions in subjects undergoing elective bowel resection.
The effects of coffee have been shown to act as a colonic stimulant. Caffeinated coffee stimulates colonic activity, most notably in the transverse/descending colon, in magnitude similar to a meal, 60% stronger than water, and 23% stronger than decaffeinated coffee. \[1\] Moreover, the consumption of both water and caffeine causes a decrease in the rectal sensory threshold for the desire to defecate, while anal sphincter pressure after caffeine intake is significantly higher than after water intake. This may result in an earlier desire to defecate. \[2\] Coffee has also been shown to have an effect on defecation by increasing rectal tone by 45% (measured with a barostat) thirty minutes after consumption. \[3\]
The purpose of this study is to evaluate the feasibility of using a realistic and anatomically accurate 3D printed simulation model for urologic bowel diversion patient education. Using a randomized two group design, we aim to determine whether the use of this model enhances patient knowledge, self-care skills, and confidence in ostomy care. We will also evaluate changes in quality of life (QOL) and patient satisfaction comparing patients exposed to the 3D model to those receiving standard of care. The secondary aim of the study is to examine the differences between groups on patient outcomes including hospital duration, mortality, emergency/urgent health care visits, readmissions, and infections. Participants will be educated using 3D model simulation as part of their preoperative education (experimental group) or have standard education without using the simulation model (comparator group). Both groups will complete quality of life (QOL), ostomy adjustment, and satisfaction with education surveys during their preoperative education visit and again during their routine follow-up visits (a) within 3 weeks after surgery, (b) between 5- 8 weeks after surgery, and (c) at approximately 3 months after surgery.
The purpose of this study is to evaluate whether a medical device/implant (InterStimTM) will help patients to have more normal bowel movements. The InterStimTM device is a neuromodulating device. Neuromodulation is a way of changing the activity of the nervous system by using electrical stimulation. InterStimTM is FDA approved to help people who have a hard time controlling their bowl movements. This is called fecal incontinence.The device is placed near a nerve root in the lower back. It works in a manner similar to a pacemaker by releasing electrical stimulation that triggers the S3 nerve root. When being placed, it is initially tested to make sure it will work using a temporary wire and then, if successful, the device is permanently implanted.
The purpose of the study is to evaluate the efficacy of Seprafilm in reducing the incidence of bowel obstruction and to evaluate the incidence of all serious adverse events (SAEs) associated with the use of Seprafilm occurring within 30 days postoperatively, and the incidence of abdominopelvic abscess within 6 months postoperatively.
Butyric acid has been shown to promote gut health and improve the microbiome in multiple adult studies. In preliminary studies in older children with inflammatory bowel disease, butyric acid was shown to be safe. However, it's suitability for infants and young children with congenital heart disease (CHD) has yet to be determined. This study will examine butyric acid supplementation in infants and children, ages 1 month to 3 years, with CHD who require cardiac surgery with cardiopulmonary bypass. Study goals include determining the safety and tolerability of butyric acid supplementation before cardiac surgery, and to identify changes in gut microbial communities, metabolic profile, and genetic markers intestinal function. Also, the study seeks to establish a reduction in inflammation (inflammatory signaling) after cardiopulmonary bypass (CPB) in participants receiving butyric acid.
This study aims to determine if improved risk stratification tools and interventions to mitigate malnutrition reduce postoperative risk in patients undergoing elective or emergent resection surgery for inflammatory bowel disease (IBD), and if adding immune modulation nutrition improves surgical outcomes. The primary objective is to assess whether preoperative malnutrition screening and intervention minimize postoperative complications. The secondary objective is to evaluate whether immune modulation nutrition in the peri-operative period decreases length of stay and major complications.
The long-term study objective is to develop optimized nutritional therapies for surgery and test them in clinical practice. This pilot study will test a microbiome-optimization diet in colorectal cancer surgery patients. The study hypothesizes that the Bacterial Intestinal Gut Modification Around Cancer Surgery (BIG MACS) Diet will provide participants with increased microbiota accessible carbohydrates (MACs) to support the microbiome and improve outcomes.
Study SYNB8802-CP-002 is designed to assess safety, tolerability, and oxalate lowering, in subjects with a history of gastric bypass surgery or short-bowel syndrome. In addition, this study will explore other PD effects relative to baseline as well as predictors of efficacy and tolerability.
This study will evaluate the safety and efficacy of Stomach Intestinal Pylorus Sparing (SIPS) as a primary bariatric surgery. In addition, we will evaluate the safety and efficacy of SIPS performed as a revisional surgery following sleeve gastrectomy (SG) in which adequate weight loss was not achieved.
Metabolic surgery is an emerging option to treat obesity-related metabolic diseases (e.g., type 2 diabetes) and prevent cardiovascular disease (CVD). Metabolic surgery can profoundly alter the gut microbiota; meanwhile, gut microbiota may affect surgical outcomes. Longitudinal studies that examined pre- to post-surgery changes in gut microbiota and its relation to cardiometabolic health after surgery are limited. Furthermore, few studies have included African Americans, a population with high rates of cardiometabolic diseases. The investigators aim to fill these research gaps by establishing a longitudinal, observational study of metabolic surgery patients and applying multi-omics to identify stool, blood, and/or tissue microbial features related to post-surgery cardiometabolic outcomes. In the current study, the investigators plan to enroll up to 300 patients who undergo metabolic surgery at Vanderbilt University Medical Center and follow them for up to 10 years after surgery. Fasting blood and stool samples will be collected at pre-surgery and 3-month, 1-year, 2-year, and 3-year post-surgery clinical visits. Tissue samples (e.g., biopsies of the liver and adipose and remnants of the stomach) will be collected during operation. Meanwhile, participants will complete a REDCap survey at baseline and 1-year, 2-year, and 3-year post-surgery. Participants' electronic medical records will be used to obtain additional information and facilitate long-term follow-up. The investigators will evaluate pre- to post-surgery changes in the fecal microbiome and fecal and blood levels of metabolites and proteins and the associations of microbiome, metabolites, and proteins with cardiometabolic improvements after surgery. This study will advance our understanding of the role of gut microbiota in metabolic surgery, which may translate into novel approaches to identify and treat obese patients for better cardiometabolic health.
The purpose of this study is to determine whether or not the total length of small intestine effects outcomes after bariatric surgery in a cohort of patients preoperatively and up to ten years postoperatively. Roux-en-Y gastric bypass and vertical sleeve gastrectomy will be the surgical groups in this study. We aim to determine if bowel length has a significant effect on long term weight loss or other nutritional deficiencies in this bariatric cohort.
This study will determine the ability of the device to draw a small amount of gas from an insufflated abdomen during laparoscopic surgery and accurately detect if gaseous content from the bowel is present.
Does mechanical bowel preparation (complete bowel cleansing)help the Surgeon with visualization of the operative field during laparoscopic pelvic reconstructive surgery?
Current management of elective bowel surgery typically involves performing a preoperative bowel preparation ("bowel prep") in many instances; however, this practice is not standardized at most institutions. Over the years, bowel preps have been used in an attempt to decrease the risk of complications associated with gastrointestinal surgery. However, there is limited adequate data to support this clinical management in the pediatric patient population. The investigator plans to perform a prospective, randomized study of our pediatric surgical patients who will undergo an elective bowel resection or ostomy closure to assess if a bowel prep prior to surgical intervention affects their postoperative course. The aim of this study is to evaluate for differences that may alter and improve future management.
Preoperative bowel preparation for surgical management of pelvic floor disorders is performed inconsistently, and includes no prep, the use of dietary changes or bowel altering interventions. Retrospective studies of emergency colonic surgery first demonstrated a low rate of infectious complications without a bowel prep. Recently, data supporting the routine use of mechanical cleansing for elective colorectal surgery has demonstrated the surgical outcomes are similar between patients that undergo a bowel preparation versus those that do not, indicating that the long held dogma of mechanical bowel preparation should be used selectively. Despite routine use, there is a paucity of literature addressing the approach to, and/or need for preoperative bowel management at the time of vaginal reconstructive or obliterative surgery. The majority of the pelvic floor disorder population is older, tending to have more bowel dysfunction (especially symptoms of constipation) than younger women. The aim of this study is to evaluate preoperative bowel management strategy as it relates to the total care of the vaginal surgery patients' intra-and post-operative bowel function and overall patient experience. Two commonly used pre-operative bowel prep strategies: no preoperative bowel prep versus clear fluids and 2-enema prep. The aim is to assess the value of bowel preparation or diet change in vaginal surgery, both from the physician's and patient's point of view. In this pilot study, subjects are randomized to either a clear liquid diet the day prior to surgery with 2 enemas and nothing by mouth (NPO) after midnight, or NPO after midnight without any dietary changes or enemas. Our aims are: \*Primary - To assess the surgeons' objective intraoperative evaluation of the effects of bowel preparation (adequate visualization, stooling during case, difficulty with bowel handling) \*Secondary - (1)To characterize the patients' experience and acceptance of preoperative bowel management regimen versus no preoperative bowel preparation(2) To characterize the patients' postoperative experience and determine if the preoperative bowel regimen affects time to first bowel movement/first normal stool as well as stool experience as recorded by bowel diary (3)Evaluate the incidence of complications between the two groups (4)Characterize other descriptive qualities of the patients' operative experience(duration of case, length of hospital stay)
"Fast-track" or "enhanced recovery" programs, which are the new standardized accelerated clinical pathways for post-operative care for colorectal surgeries, have three goals: to 1) quicken the return of bowel function (as evidenced by passage of flatus and stool), 2) decrease the length of hospital stays, and 3) decrease the rate of overall complications. Aside from several components, or interventions that can vary from institution to institution, these programs share three common modalities: early oral feeding, protocol pain management regimens less dependent on opioid use, and early mobilization (i.e. ambulation). Evidence-based practice has shown that the modalities individually contribute significantly to the program goals except for post-operative ambulation, which has not been shown to increase bowel function although it contributes to decreased pulmonary complications and early discharge of patients. Still, surgeons continue to advocate for early ambulation to aid in the return of bowel function despite the lack of clear evidence supporting this notion. The investigators propose a randomized, prospective clinical trial exploring the impact that post-operative ambulation has on the outcome of colorectal surgeries, particularly on the return of bowel function and the length of hospital stay. With the use of pedometers to measure physical activity, the investigators will subject patients to either the current traditional post-operative care or one with an aggressive ambulation regimen. Through the use of radiopaque markers, the investigators hope to correlate increased ambulation with increased gastrointestinal motility function to prove the impact of early ambulation on post-operative care.
The purpose of this study is to determine if the use of SurgiWrapTM: (1) prevents/lowers the incidence of Grade 2 or higher soft tissue attachments under the incision made during abdominal surgery, (2) reduces post-operative bowel obstruction.
The specific aim of this prospective, randomized controlled trial is to compare the effect of chewing gum on the return of bowel function in a group of patients undergoing spinal surgery with a group of matched controls that do not receive any chewing gum. A 24-hour reduction in time to passage of first flatus will be considered an important clinical difference. The research questions are: 1. Does providing chewing gum post-operatively hasten the return of bowel function? 2. Does providing chewing gum post-operatively reduced overall length of stay? 3. Does providing chewing gum post-operatively have any associated complications? 4. Does providing chewing gum post-operatively result in higher objective outcomes scores? The secondary aims are: 1. To compare hospital length of stay between the groups with a mean of ½ day considered clinically important. 2. To compare time until tolerating regular diet as defined as two consecutive meals with no complications with 24 hours considered statistically significant. 3. To compare incidence and nature of complications between the two groups. 4. To compare the time until completion of rehab milestones with 1 day being considered clinically important. 5. To compare the requirement for nutrition evaluations 6. To compare SF-12 scores as a marker of patient satisfaction with a difference of 10 points or more measured between the two groups upon discharge from hospital and at six-weeks after surgery.
The purpose of the study is to determine if the myoelectrical measurements made by the G-Tech Wireless Patch System correlate with clinical markers of postoperative recovery such as passage of flatus/bowel movement, oral tolerance of diet and discharge readiness. Subsequently the data will be studied to establish which information in the signals is important in determining when to feed patients and possibly discharge them..
The purpose of the study is to determine if the myoelectrical measurements made by the G-Tech Wireless Patch System correlate with clinical markers of postoperative recovery such as passage of flatus/bowel movement, oral tolerance of diet and discharge readiness. Subsequently the data will be studied to establish which information in the signals is important in determining when to feed patients and possibly discharge them. These pilot prospective, open clinical studies suggests that myoelectrical activity, measured on the abdominal surface with a noninvasive wireless patch system, carries predictive value in determining time to feeding and time to flatus following open abdominal surgery. Having such information in advance of clinical measures could facilitate timely interventions, be it early feeding or delaying feeding as dictated by the patient's unique recovery profile. The G-Tech Wireless Patch System would provide a unique insight into the process allowing for a tailored protocol that could improve patient satisfaction and optimize recovery. The system could also enable feedback on the impact to the overall gastrointestinal myoelectrical activity of medications, particularly opioids, used for pain management that are known to inhibit gastrointestinal function by disrupting the normal recovery patterns of colonic motility.23-25 While it remains to be seen, in addition to predicting time to flatus/bowel movement early on, the ability to continue monitoring the patient may allow one to predict onset of secondary complications, such as wound infections or anastomotic leaks, that are associated with ileus. Similarly, given the wireless noninvasive nature of the system the patients could be discharged home with the patches, whereby they would serve as a remote monitoring tool. This could be particularly useful in cases where the patients may have been discharged early and may be at a high risk for readmission. The system would then send updates/alerts to the care team for management and potentially avoid preventable readmissions.
The purpose of this study is to investigate whether the use of a preoperative antibiotic bowel regimen is associated with a reduced risk of deep organ/space surgical site infection in gynecologic oncology surgery.
This multicenter, randomized, double-blinded, placebo-controlled study will evaluate the effect of TU-100 on resolution of postoperative ileus (POI) in subjects undergoing open or laparoscopic bowel resection (BR).
The objective of this study is to compare the efficacy of naldemedine versus placebo and to assess its effect on the time to gastrointestinal (GI) recovery following surgeries that include bowel resection and bowel transection.
This study is designed as a prospective pilot study for longitudinal assessment of fecal microbiome related to medical and surgical weight loss. The investigators follow the standard of care for perioperative and intraoperative management of study participants. The only addition to the standard of care protocol will be collection of fecal samples at 3 time points. This will enable investigators to compare changes in and effects by microbiota after low-calorie diet versus after bariatric surgery .
This is a 3 arm Phase 3 study to evaluate the safety and efficacy of the addition of veliparib plus carboplatin versus the addition of carboplatin to standard neoadjuvant chemotherapy versus standard neoadjuvant chemotherapy in subjects with early stage TNBC.
This study is a biospecimen discovery project that will serve as a pilot for a comprehensive 'omics approach using fresh core biopsy tissue and blood samples for DNA and protein analysis, as well as paired tumor-normal exome DNA and RNA sequencing.
