Nineteen cats were randomly divided into two groups, 7 cats (group A) recieved about 200 times spotty injections of total of 2 ml of 94% alcohol in pancreatic parenchyma and 12 cats (group B) underwent intraductal alcohoh, partial obstruction of the main pancreatic duct (MPD) and intraparenchymal alcohol. Acute necrotizing pancreatitis occurred in all of the experimental cats after operation. 2 cats in group A (28.6%) died within 48 hours postoperatively. 4 cats in group B (33.3%) died, among them, 3 within 48 hours and 1 died after 2 weeks. Morphological and functional recovery of the exocrine pancreas were found in all the 5 survivals in group A, while 8 cats in group B developed chronic pancreatitis 15 weeks after the operation. The above results show that simple pancreatic necrosis can be recovered after eliminating the etiological factors and if these factors, whatever is primary or secondary still exist and continue to damage the pancreas, chronic pancreatitis may develop.
【摘要】 目的 探讨血浆胰蛋白酶原激活肽(trypsinogen activation peptide,TAP)水平与重症急性胰腺炎(severe acute pancreatitis,SAP)胰腺坏死的关系。方法 2008年6月1日—2008年12月31日,采用ELISA法测定本院的35例SAP患者血浆TAP水平,并与胰腺增强CT扫描结果作对比,分析血浆TAP水平与胰腺坏死的关系,以及SAP无胰腺坏死组与SAP胰腺坏死组血浆TAP水平的差异。结果 入院时血浆TAP水平预测胰腺坏死的最佳截值点是10.43 nmol/mL,其敏感性、特异性、阳性预测值、阴性预测值分别为75%、73.9%、60%、15%,阳性比为2.87,阴性比为0.338。入院第1天血浆TAP水平预测胰腺坏死的最佳截值点是6.91 μmol/L,其敏感性、特异性、阳性预测值、阴性预测值分别为90.9%、65.2%、55.6%、6.3%,阳性似然比为2.61,阴性似然比为0.001。SAP胰腺坏死组入院时、入院第一天血浆TAP水平高于SAP无胰腺坏死组(Plt;0.05)。结论 血浆TAP水平变化与SAP病情变化密切相关,病程早期检测血浆TAP水平有助于SAP患者胰腺坏死的预测
目的:探讨血清钙与胰腺坏死的关系.方法:四川大学华西医院中西医结合科2003年9月~2005年3月收治的200例急性胰腺炎患者,根据CT结果分为坏死组和非坏死组,根据所有患者测得的血清钙相应的真阳性率和假阳性率做出ROC曲线以预测胰腺坏死。结果:ROC曲线下面积为0.436。结论:血清钙高低不能预测胰腺坏死。
ObjectiveTo explore the safety and feasibility of retrolaparoscopy in treatment of severe acute pancreatitis complicated with infected pancreatic necrosis. MethodsClinical data of 20 patients with severe acute pancreatitis complicated with infectious pancreatic necrosis who received retrolaparoscopy treatment in our hospital from May 2017 to May 2022 were retrospectively collected. ResultsAmong the 20 patients, 18 patients underwent percutaneous catheter drainage, 1 pregnant patient with severe acute pancreatitis underwent laparotomy drainage in the first phase, and 1 patient underwent laparotomy drainage in the first phase from another hospital. All patients underwent successful retroperitoneal drainage, microscopic debridement and drainage were performed. The operation time was 68–106 minutes, (89.8±11.7) minutes; intraoperative bleeding was 100–300 mL, (171.3±61.0) mL; hospitalization was 28–62 d, with median time of 48 d. After the operation, the systemic poisoning symptoms of the patients were quickly relieved. One patient underwent twice retroperitoneoscopic debridement surgeries, and the remaining patients underwent only once retroperitoneoscopic debridement drainage surgery. There were no complications in 17 patients, but 1 patient was complicated by colonic fistula after surgery, 2 patients suffered from abdominal bleeding. After the operation, 20 patients were interviewed, and the follow-up time was 6–62 months, with the median of 31 months. During postoperative follow-up period, the patients’ symptoms completely disappeared and there was no recurrence. ConclusionThe retrolaparoscopic approach in treatment of severe acute pancreatitis complicated with infected pancreatic necrosis is safe and effective, and has few complications.
ObjectiveTo evaluate the clinical efficacy of surgical intervention combined with endoscopic ultrasound-guided transluminal drainage in the treatment of infected pancreatic necrosis (IPN). MethodsA retrospective, historical control study was conducted. A total of 98 patients with acute pancreatitis (AP) complicated with IPN who met the inclusion and exclusion criteria and were admitted to the Third People’s Hospital of Chengdu from June 2016 to January 2023 were selected as the research objects. The endoscopic ultrasound-guided transluminal drainage was carried out in our hospital in June 2020. In this study, patients treated before May 2020 were divided into the non-EUS group (52 cases), and patients treated after June 2020 were divided into the EUS group (46 cases). The baseline data, surgical intervention, length of hospital stay, length of intensive care unit (ICU) stay, infection time, incidence of multiple organ dysfunction syndrome (MODS), survival situation, short-term and long-term complications, and other indicators were compared between the two groups. ResultsThe number of percutaneous catheter drainage (PCD, 1.0 vs. 1.0), the number of PCD drainage tube (1.0 vs. 2.0), the number of retroperitoneal debridement drainage (1.0 vs. 2.0), the total length of hospital stay (42.0 d vs. 45.5 d), the length of ICU stay (11.0 d vs. 14.0 d), the length of infection time (10.5 d vs. 18.5 d), the incidences of MODS [43.5% (20/46) vs. 67.3% (35/52)] and residual infection [28.3% (13/46) vs.48.1% (25/52)] in the EUS group were shorter (or lower) than those in the non-EUS group (P<0.05); but there were no significant differences in the number of endoscopic pancreatic stent implantation, the number of laparotomy, the number of laparoscopic surgery, and the incidences of abdominal bleeding, gastrointestinal fistula, gastrointestinal obstruction, chronic pancreatic fistula, chronic pancreatitis and incisional hernia between the two groups (P>0.05). ConclusionFor patients with AP complicated with IPN, surgical intervention combined with endoscopic ultrasound-guided transluminal drainage can reduce the number of PCD and drainage tube, shorten the total length of hospital stay, the length of ICU stay and infection, as well as reduce the incidences of MODS and residual infection.
