Three Year Outcomes of Combined Hydrus Microstent With iTrack Canaloplasty

The goal of this study is to learn if combining minimally invasive glaucoma surgery (MIGS) procedures with different mechanisms of action increases the effectiveness of MIGS. The main question the study aims to answer is: Does combining viscodilation (a surgical technique, often used in glaucoma treatment, that involves using a high-viscosity, elastic gel to widen and open the Schlemm's canal, a main drainage channel in the eye) with the iTrack catheter, along with the Hydrus microstent, show better reduction in intraocular pressure than cataract surgery alone? Researchers will retrospectively review charts of patients who have open-angle glaucoma who have undergone combination Hydrus implantation and 360-degree iTrack canaloplasty with concomitant cataract surgery, who have at least 36 months of clinical follow-up data. Baseline demographic information and severity of glaucoma will be recorded, as will change from baseline yearly to three years in average optical coherence tomography (OCT) retina nerve fiber layer (RNFL) measurements and visual field (VF) pattern standard deviation. Safety outcomes and the percentage of eyes requiring secondary surgical intervention will be recorded at yearly time points.

Laparoscopic Versus Robot-assisted Left-sided Pancreatectomy for Benign and Pre-malignant Lesions (DIPLOMA-3)

The DIPLOMA-3 trial is an international, multicenter, patient-blinded randomized controlled trial comparing laparoscopic and robot-assisted left-sided pancreatectomy. Patients with an indication for elective left-sided pancreatecomy for benign or premalignant lesions in the body or tail of the pancreas and considered eligible will be randomized between laparoscopic and robot-assisted resection.

Robot-assisted Versus Open Lateral Pancreaticojejunostomy for the Treatment of Symptomatic Chronic Pancreatitis (PANACOTTA)

PANACOTTA is a multicenter randomized controlled trial including patients with symptomatic chronic pancreatitis and a dilated main pancreatic duct to either robot-assisted or open lateral pancreaticojejunostomy. The PANACOTTA trial will assess the post-operative quality of recovery following robot-assisted versus open lateral pancreaticojejunostomy.

Efficacy of the Entire Papilla Preservation Technique With and Without the Use of L-PRF as a Regenerative Material for the Treatment of Infrabony Defects

The goal of this clinical trial is to evaluate the efficacy of using L-PRF (leukocyte and platelet rich fibrin clot) as an autologous filling material in conjunction with the EPP (entire papilla preservation) technique for the treatment of interproximal intraosseous periodontal defects, compared to the same technique without L-PRF regarding clinical periodontal parameters and obtained radiographic parameters. It will also report possible postoperative complications and evaluate postoperative sensitivity. The main questions it aims to answer is: • What is the effectiveness of LPR-F in conjunction with a complete papilla preservation (EPP) technique for the treatment of intrabony periodontal defects in CESA (health care center) patients in terms of clinical and radiographic periodontal parameters compared to the use of the same technique without L-PRF? A non-randomized controlled clinical trial will be conducted on patients at CESA of the Universidad de los Andes. In 30 patients, 30 periodontal defects associated with a pocket with probing depths equal to or greater than 6 mm will be treated using the complete papilla preservation technique, either with L-PRF filling or without any filling material, assigned randomly to each intervention (15 participants in each group). Researchers will evaluate clinical and radiographic parameters at baseline and 6 months post-surgery. Patients will report their level of pain 24 hours and 7 days after surgery.
