Project description:BackgroundPeriampullary diverticula (PAD) often detected during endoscopic retrograde cholangiopancreatography (ERCP), and ERCP remains the primary approach to treating bile duct stones, and papilla cannulation plays a critical role in the success of ERCP. PAD can reduce the cannulation success rate. Needle knife precut greatly promoted the clinical application of precut incision. However, this approach also increases the risk of various adverse events. The present study aimed to compare the perioperative outcomes of pancreatic duct guide wire-assisted needle knife precut and conventional needle knife precut for PAD with difficult cannulation.MethodsA total of 230 cases of PAD with difficult cannulation of the duodenal papilla diagnosed by ERCP between June 2009 and December 2021 were retrospectively reviewed. The exclusion criteria were set as follows: patients with ERCP history, coagulopathy prothrombin time two times longer or platelet (PLT) count ≤70×109/L, or an inability to tolerate endoscopy due to severe heart/lung diseases. Pancreatic duct guide wire-assisted needle knife precut (Group A) was performed in 135 cases, and conventional needle knife precut (Group B) was performed in 95 cases. All clinical data were analyzed retrospectively. SPSS20.0 statistical software was used for the t-test and analysis of variance. P<0.05 was considered statistically significant.ResultsThe operating time of the needle knife precut was significantly shorter in Group A (18.44±6.65 min) compared with Group B (32.05±13.15 min, P<0.01). Moreover, the success rate of the cannulation was markedly higher in Group A (100%, 135/135) compared with Group B (78.9%, 75/95). Intraoperative complications occurred in 15 (11.1%) and 26 (27.4%) cases in Groups A and B, respectively (P<0.01). Postoperative complications occurred in 10 (7.4%) and 17 (17.9%) cases in Groups A and B, respectively (P<0.01). Our results showed notable differences in the operating time, success rate of cannulation, intraoperative complication rates, and postoperative complication rates between the two approaches.ConclusionsPancreatic duct guide wire-assisted needle knife precut appeared to be a safe and effective modality for PAD with difficult cannulation in the duodenal papilla.

Project description:Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered gastrointestinal anatomy has been reported to be useful. However, selective biliary cannulation through the papilla is difficult in cases with surgically altered gastrointestinal anatomy. Herein, we report a successful biliary cannulation using a pancreatic duct (PD) stent in patients with Roux-en-Y anatomy. A 70-year-old man who underwent total gastrectomy with Roux-en-Y anatomy was admitted to our hospital with jaundice due to recurrence of gastric cancer. ERCP was performed for biliary drainage. We approached the papilla using a short-type single-balloon enteroscope (SIF-H290; Olympus Medical Systems). Because the papilla was positioned tangentially, it was difficult to adjust the catheter in the direction of the bile duct. As only a PD could be cannulated, we placed a guidewire in the PD. Although we attempted the double-guidewire technique using a guidewire placed in PD, selective biliary cannulation was difficult. Therefore, we placed a PD stent 5Fr-5cm (Geenen, Pancreatic Stent Sets, Cook Medical, Bloomington, IN, USA) to assist biliary cannulation. We inserted a catheter crossing the PD stent. With this, selective biliary cannulation was successful. We successfully performed selective biliary cannulation using the PD stent as we were able to fix the papilla, straighten the common channel and the axis of the bile duct, and not restrict scope movement by not using the PD guidewire placement method. This novel technique using a PD stent appears to be useful in patients with surgically altered gastrointestinal anatomy.

Project description:PURPOSE:To develop a methodology for cannulating porcine retinal venules using a robotic assistive arm after inducing a retinal vein occlusion using the photosensitizer rose bengal. METHODOLOGY:Retinal vein occlusions proximal to the first vascular branch point were induced following intravenous injection of rose bengal by exposure to 532nm laser light delivered by slit-lamp or endolaser probe. Retinal veins were cannulated by positioning a glass catheter tip using a robotically controlled micromanipulator above venules with an outer diameter of 80?m or more and performing a preset piercing maneuver, controlled robotically. The ability of a balanced salt (BSS) solution to remove an occlusion by repeat distention of the retinal vein was also assessed. RESULTS:Cannulation using the preset piercing program was successful in 9 of 9 eyes. Piercing using the micromanipulator under manual control was successful in only 24 of 52 attempts, with several attempts leading to double piercing. The best location for cannulation was directly proximal to the occlusion. Infusion of BSS did not result in the resolution of the occlusion. CONCLUSION:Cannulation of venules using a robotic microassistive arm can be achieved with consistency, provided the piercing is robotically driven. The model appears robust enough to allow testing of therapeutic strategies aimed at eliminating a retinal vein thrombus and its evolution over time.

Project description:BackgroundWe have optimized a technique for cannulation of mesenteric lymph duct (MLD) in mice. Mice have low rates of intestinal lymph production; the MLDs are smaller and associated with fragile vasculature. Previous protocols for lymph collection based on the open lymph fistula model were associated with low success rates in mice. Bariatric surgery procedures worsen success rates due to postoperative adhesions and GI rearrangement. We have used this procedure to collect mesenteric lymph from mice undergoing bile diversion from gall bladder to ileum (GB-IL).HypothesisWe hypothesize that peptide YY (PYY) levels in mesenteric lymph will increase following nutrient delivery in mice undergoing bile diversion from gall bladder to ileum (GB-IL).Methods and resultsWe observe that cannulation of the MLD using a needled-catheter maintains lymph vessel integrity, prevents excessive lymph leakage, and is less traumatic, leading to high success rates (>95%). PYY levels in mesenteric lymph after GB-IL were significantly higher post nutrient infusion. The procedure takes approximately 20 min; small rodent surgical experience and practice are required for success.ConclusionsIntestinal lymph can be collected from mice, including those undergoing bariatric surgical procedures with high success rates by cannulation of the mesenteric lymph duct.

Project description:ObjectivesWe demonstrate the feasibility and safety of robotics-assisted left atrial appendage clip exclusion in clinical practice.MethodsAnalysis of a single center robotics-assisted left atrial appendage clip exclusion experience using an epicardial linear clip device in patients with atrial fibrillation with high-risk of thromboembolic stroke and intolerance to oral anticoagulants.ResultsDuring the period from December 2017 to September 2020, we performed 42 robotics-assisted left atrial appendage clip exclusions in response to increased risk of bleeding in patients with atrial fibrillation and intolerance to oral anticoagulants. The average congestive heart failure, hypertension, age, diabetes, stroke, and vascular disease score was 5.2 ± 1.6 and hypertension, abnormal liver or kidney function, stroke, bleeding, labile international normalized ratio, elderly, drugs (aspirin, other antiplatelets, or anticoagulants) score was 4.5 ± 0.9. No patients died intraoperatively or within 30 days, or due to conversion to thoracotomy, intraoperative complications, or failure to apply the clip satisfactorily. The procedure was successfully completed despite pericardial adhesions in 2 patients with prior coronary bypass grafts and 3 with postpericarditis scars. Intraoperative transesophageal echocardiography was performed in 38 out of 42 patients; satisfactory exclusion with left atrial appendage stump <5 mm was confirmed in all. Average length of stay was 3.4 ± 3 days with 12 out of 42 patients discharged within 24 hours. Oral anticoagulants were discontinued in 41 out of 42 patients and no cases of 30-day stroke, myocardial ischemia, or new arrhythmias were observed. One case of hemothorax required thoracoscopy a day later. There was no reported thromboembolic stroke or transient ischemic attack at 12 months. One case of late lacunar stroke was due to in situ small intracranial vessel thrombosis without left atrial appendage thrombus on imaging.ConclusionsRobotics-assisted left atrial appendage clip exclusion is a safe and feasible minimally invasive method for left atrial appendage management in patients with atrial fibrillation with intolerance to oral anticoagulants and increased risk of thromboembolic stroke.
