Filter by:The purpose of this study is to evaluate whether a fluorescent die and a special infrared camera can assist with the identification of the important structures during laparoscopic cholecystectomy. This finding may assist surgeons to perform laparoscopic cholecystectomy in less time and in a safer fashion than standard laparoscopic cholecystectomy.
Opioids are the corner stone in the treatment of post operative pain. Because of the several side effects of opiods, non-steroidal anti-inflammatory drugs are usually added postoperatively to decrease the total requirements of opioids. However, non steroidal anti-inflammatory drugs have side effects of their own. Vitamin C, with virtually no side effects when used on short-term basis, has been shown to have promising analgesic effects in chronic pain and acute pain relief following orthopedic surgeries. The investigators propose to assess the role of a prophylactic single dose (2g) of vitamin C in reducing the intensity of pain and the consumption of opioids in patients undergoing laparoscopic cholecystectomy at AUB-MC. All eligible patients undergoing laparoscopic cholecystectomy at AUB-MC will be included in the study. Patients will be randomized into two groups to receive either single dose oral vitamin C (2g) (Study Group) or identically looking placebo capsules (Control Group). Both the patients and the investigation team will be blinded to the type of intervention. Intraoperative anesthesia management will be similar for both groups. Postoperative pain control will be achieved with patient controlled analgesia via a patient controlled morphine pump in both groups. At several time intervals and up to 24 hours postoperatively, the pain scores, morphine consumptions, nausea/vomiting scores, sedation scales, itching scales, and patient satisfaction scales will be obtained for all patients. Also, the peak vitamin C concentration will be determined for each patient. Patients demographics will be obtained and compared between both groups. The differences in pain scores, morphine consumptions, nausea/vomiting scores, and sedation, itching, and patient satisfaction scales will be compared between the two groups with the Student-t test, the analysis of variance, the Fisher exact test, and the Kruskal-Wallis test. The peak vitamin C plasma concentration will be correlated with the pain scores in each group using regression analysis. This study will provide relevant information on whether a single dose (2g) of vitamin C can reduce morphine requirements and non steroidal anti-inflammatory drugs need and thus eliminating their side effects in patients undergoing laparoscopic cholecystectomy.
Hypothesis: Natural orifice transgastric cholecystectomy with laparoscopic assist will be feasible and have comparable complication rates as standard lap cholecystectomy. Patient benefits will include less pain and scaring.
The investigators would like to conduct a prospective, randomized non-inferiority study to compare clinical outcome between endoscopic ultrasound (EUS) guided gallbladder drainage and percutaneous transhepatic gallbladder drainage (PTGBD) in high risk acute cholecystitis patients.
The aim of this work is to evaluate which of the two types of operation (traditional/open and laparoscopic) has more impact on patients who were operated electively due to their chronic calculous cholecystitis.
Assess whether postoperative antibiotics after cholecystectomy for acute lithiasic cholecystitis little or moderately severe, is effective and therefore justified. The main objective is to compare the occurrence of postoperative infectious complications including surgical site infections (SSI) and remote infections after early cholecystectomy (performed within 5 days after onset of symptoms) for acute lithiasic cholecystitis (ALC) little or moderately serious (without organ dysfunction) with and without postoperative antibiotics. The secondary objectives are: - Rates of infectious complications according to duration of preoperative antibiotic - Influence of surgical drainage after surgery for occurrence of postoperative infectious complications - Analysis of the nature of infectious complications (surgical site infections, remote surgical site infections) - Comparison of germs found in the bile during the postoperative infectious complications - Duration of hospitalization - Readmission rate for surgical site infections - Rate of reoperation for surgical site infection - Overall mortality rate at 30 days - Mortality rates specific to 30 days
Transvaginal hybrid procedures especially the transvaginal hybrid cholecystectomy are of interest as an available NOTES-Procedure for the clinical routine. Few authors have demonstrated the feasibility and safety in a selected patient collective. The aim of this prospective data collection is to evaluate the feasibility in the clinical routine in a non select patient collective. Therefore all patients giving the informed consent to the transvaginal hybrid cholecystectomy will be included and assessed concerning feasibility to perform the transvaginal approach and complete the operation transvaginally.
In the developmental stage of laparoscopic cholecystectomy it was considered 'unsafe' or 'technically difficult' to perform laparoscopic cholecystectomy for acute cholecystitis. With increasing experience in laparoscopic surgery, a number of centers have reported on the use of laparoscopic cholecystectomy for acute cholecystitis, suggesting that it is technically feasible but at the expense of a high conversion rate, which can be up to 35 per cent and common bile duct lesions. The HARMONIC SCALPEL® (H) is the leading ultrasonic cutting and coagulating surgical device, offering surgeons important benefits including: minimal lateral thermal tissue damage, minimal charring and desiccation. H technology reduces the need for ligatures with simultaneous cutting and coagulation: moreover there is not electricity to or through the patient H has a greater precision near vital structures and it produces minimal smoke with improved visibility in the surgical field. In retrospective series LC performed with H was demonstrated feasible and effective with minimal operating time and blood loss: it was reported also a low conversion rate (3.9%). However there are not prospective randomized controlled trials showing the advantages of H compared to MD (the commonly used electrical scalpel) in LC. Aim of this RCT is to demonstrate that H can reduce conversion rate compared to MD in LC for AC.
The role of teleradiology has far reaching implications for the health of remote and underserved populations. The ability to coordinate radiographic evaluation and diagnosis from a distance has the potential to raise the standard of patient care throughout the world. Perhaps the safest and most cost effective mode of teleradiology today is telesonography. The current project attempts to determine the extent that telesonography improves the standard of care within a rural government-run primary clinic within the Dominican Republic. The work reported herein is intended to compare the use of telesonography to the current standard of sonographic examination (referral to government hospital 60km from target clinic). The study was conducted by randomly assigning 100 patients with clinical indications for sonographic examination into experimental and control groups. Following a 60-day implementation period, the following research questions will be addressed: 1) To what extent does the use of asynchronous telesonography increase the percentage of definitive diagnoses based on the total number of scans (definitive diagnoses / total number of scans)? 2) To what extent does the use of asynchronous telesonography increase the continuity of care for patients? 3) To what extent does the elapsed time between scanning and final radiological interpretation decrease with the use of asynchronous telesonography? This study will also look at the history of telemedicine / telesonography and its dissemination into the mainstream practice of medicine, explore training protocols that may be used to assist others to establish new telesonography programs in a developing nations, and discuss both advances and persistent barriers to the implementation of telesonography programs. Hypothesis: The use of a store-and-forward telesonography system in this setting will increase the speed and number of final diagnoses per scan received by the target clinic and will increase the continuity of care by increasing the number and speed of follow-up appointments to the target clinic.
This is a pilot study to investigate the ability of fluorodeoxyglucose-positron emission tomography (FDG-PET) and Positron emission tomography-computed tomography (PET/CT) as a direct method of detecting infection and/or inflammation of the gallbladder.
