Minimally Invasive Surgery for Necrotizing Pancreatitis: A Case Report

Surgical Science 2024年第9期15卷 514-521页

Introduction: Necrotizing pancreatitis management is complex and varies significantly among clinicians. Minimally invasive approaches like transgastric necrosectomy via laparoscopy are emerging as effective treatment options. This case report underscores the technique’s efficacy, clinical outcomes, and role in reducing complications. Clinical Observation: A 59-year-old male with a history of smoking and alcoholism presented with severe abdominal pain, nausea, and vomiting. Over the following weeks, he developed symptoms including asthenia, weight loss, and melena. Diagnostic workup revealed severe anemia and Balthazar E necrotizing pancreatitis, with significant intra-abdominal fluid collections and signs of infection. After initial conservative management, the patient underwent transgastric necrosectomy via laparoscopy due to deteriorating clinical status. The procedure involved removing necrotic tissue and performing a cystogastroanastomosis and jejunostomy. Postoperative care included fasting, parenteral nutrition, broad-spectrum antibiotics, and enzymatic replacement. The patient recovered well, with reduced necrotic tissue on follow-up imaging, and was discharged twelve days post-surgery [1]. Conclusion: Transgastric necrosectomy by laparoscopy is a valuable first-line surgical option for patients with symptomatic necrotizing pancreatitis, particularly in cases without prior interventions. This minimally invasive technique helps reduce major complications and mortality, offering a less invasive alternative to traditional open necrosectomy. The multidisciplinary approach and careful postoperative management were crucial to the patient’s favorable outcome. The case highlights the potential of transgastric necrosectomy as an effective treatment strategy in managing complex pancreatitis cases, including those with associated duodenal perforation [2].

Background: Duodenoscope-related multidrug-resistant organism(MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography(ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. Methods: This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score(1 to 10) on performance rating of the single-use duodenoscope, and adverse event(AE) rate. Results: A total of 66 patients(26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47(71.2%) grade 3 and 19(28.8%) grade 4. The technical success rate was 98.5%(65/66). Procedural duration was 64(interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66(1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients(6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis(PEP), 1 cholangitis and 1 ***: Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.

Increased CO2 Levels during the First Half of Incubation at High Altitude Modifies Embryonic Development of Fertile Leghorn Breeder Eggs

引用

Food and Nutrition Sciences 2024年第7期15卷 524-547页

The exchange of oxygen (O2) and carbon dioxide (CO2) within an incubator has a significant impact on embryonic development (ED) and hatching processes. This study examines the influence of non-ventilation (NV) conditions during the first ten days of incubation at high altitudes on Leghorn hens hatching eggs. Five hundred four hatching eggs were equally divided into three treatment groups and placed in twelve incubators (R = 4). The first group was subjected to standard ventilated conditions (V) during the setting phase. The ventilation inlet holes of the remaining incubators in the NV treatments were closed with either micropore (M) or polypropylene (P) tape, referred to as NVM and NVP groups, respectively. These two different airtight settings were intended to allow for a gradual rise in CO2 naturally generated by the embryos. Results indicate that carbon dioxide concentration gradually increased during the first half of incubation, reaching 1.42% in the NVM group and 1.20% in the NVP group, while the V condition group remained at 0.15%. From 10 days of incubation onwards, normal V conditions were restored in all incubators. The highest hatchability of fertile eggs (HFE) was shown by the NVP group (55.7%), followed by the V (52.6%) and NVM (38.6%) groups. The NVP group showed a greater yolk-free body mass (YFBM) from 10 days of incubation until the hatch basket transfer. NV conditions during the first 10 days of incubation at high altitude produced higher YFBM with gradually decreasing yolk sac mass. In comparison to the NVM and V conditions, the particular NVP condition showed a beneficial impact on the quality of hatched chicks. Sustaining NVP condition (1.2% of CO2) throughout the first half of incubation at high altitude generated the optimal environment in the incubator ensuring the best hatchability results. This study highlights how important it is for hatchery managers to recognize the influence of low O2 and high levels of CO2 on the development trajectori
