Abstract Background This study aimed to investigate the feasibility, effectiveness, and safety of pancreatic duct stenting in managing acute biliary pancreatitis (ABP) necessitating endoscopic retrograde cholangiopancreatography (ERCP). It further aimed to provide valuable insights for subsequent clinical diagnosis and treatment. Methods This research employs an observational retrospective case–control study design, encompassing patients with ABP who underwent ERCP at the hepatobiliary surgery department of the General Hospital of Ningxia Medical University between August 1, 2018, and December 31, 2020. A total of 229 cases were screened based on inclusion and exclusion criteria. Regardless of ABP severity, patients were categorized into the stent group (141) and the non-stent group (88). Changes in blood amylase (Amy), lipase (LIP), leukocyte count (WBC), total bilirubin (TBIL), alanine aminotransferase (ALT), hematocrit (HCT), and creatinine (CR) were compared between the two groups. Moreover, variables such as recovery time for oral feeding, hospitalization duration, hospitalization costs, local complications, systemic complications, and new organ failure were recorded to assess the therapeutic effect of pancreatic duct stenting. Results No significant differences were observed in gender, age, Acute Physiology and Chronic Health Evaluation (APACHE) II score, ABP severity grade, organ failure (OF), cholangitis, or biliary obstruction between the pancreatic stent and non-stent groups (P > 0.05). There was no significant difference in the incidence of complications related to acute pancreatitis between the two groups (P > 0.05). The median fasting and hospitalization times of patients in the stent group were significantly shorter than those in the non-stent group (P 0.05). There were no significant variations in white blood cell (WBC) count, TBIL, ALT, and creatinine (Cr) at admission, 72 h, and in the differences between the two groups (P > 0.05). The levels of Amy at admission and 72 h in the stent group were significantly higher than those in the non-stent group (P 0.05), the mean 72-h HCT in the stent group was 38.39% (95% confidence interval [CI] 37.82%–38.96%) was lower than that in the non-stent group (39.44%, 95% CI 38.70–40.17%) (P

There was no significant difference in the incidence of complications related to acute pancreatitis between the two groups (P > 0.05). The median fasting and hospitalization times of patients in the stent group were significantly shorter than those in the non-stent group (P < 0.05). No significant differences between the groups were observed in hospitalization costs and in-hospital mortality (P > 0.05). There were no significant variations in white blood cell (WBC) count, TBIL, ALT, and creatinine (Cr) at admission, 72 h, and in the differences between the two groups (P > 0.05). The levels of Amy at admission and 72 h in the stent group were significantly higher than those in the non-stent group (P < 0.05). The differences in LIP and HCT in the stent group were considerably higher than in the non-stent group (P < 0.05). Although no significant differences were observed in mean Amy and LIP between the two groups (P > 0.05), the mean 72-h HCT in the stent group was 38.39% (95% confidence interval [CI] 37.82%–38.96%) was lower than that in the non-stent group (39.44%, 95% CI 38.70–40.17%) (P < 0.05). Conclusion: In the stent group, feeding time and hospital stay were significantly shorter than those in the non-stent group. No significant differences were observed between the two groups in the incidence of complications and mortality. The HCT value decreased more rapidly in the stent group. Early pancreatic stent implantation demonstrated the potential to shorten the eating and hospitalization duration of patients with ABP, facilitating their prompt recovery.

Background and Aim Complications of endoscopic treatment are reported more and more often as a result of popularization of pancreatic endotherapy. Our study presents the results of treatment in patients with intraductal pancreatic stent fragmentation diagnosed during endotherapy of chronic pancreatitis. Methods Retrospective analysis of 2496 endoscopic retrograde cholangiopancreatography procedures which were carried out in 607 patients at the Gastrointestinal Endoscopy Unit of the University Clinical Center in Gdansk. Results In the course of pancreatic endotherapy, intraductal pancreatic stent fragmentation was stated during 33 of 2496 (0.013%) procedures in 33 of 607 (5.44%) patients with chronic pancreatitis. In 33 patients, there were 46 intraductal fragments of broken stents. Most patients were asymptomatic. In 31/33 patients, fragments of broken stents were removed from the pancreatic duct endoscopically. In the case of two patients, endoscopic management was ineffective and they were treated surgically. Altogether, 44/46 stent fragments were removed endoscopically. Most fragments of pancreatic stents were removed during the first endoscopic procedure. One fragment of a broken stent was retrieved with polypectomy snare and four with Dormia basket. The remaining fragments of broken pancreatic stents were removed with rat-tooth forceps. Conclusions Intraductal fragmentation of pancreatic stent is a rare complication of pancreatic endotherapy and it often has an asymptomatic course. Most fragments of broken pancreatic stents can be removed endoscopically from the pancreatic duct with an acceptable complication rate. [ABSTRACT FROM AUTHOR]

Background: To evaluate the management and outcomes of blunt pancreatic injuries based on the integrity of the major pancreatic duct (MPD).Methods: Between August 1996 and August 2015, 35 patients with blunt pancreatic injuries underwent endoscopic retrograde pancreatography (ERP). Medical charts were retrospectively reviewed for demography, ERP timing, imaging findings, management, and outcome.Results: Of the 35 patients, 21 were men and 14 were women, with ages ranging from 11 to 70 years. On the basis of the ERP findings, we propose a MPD injury classification as follows: class 1 indicates normal MPD; class 2, partial injury with intact MPD continuity; and class 3, complete injury with disrupted MPD continuity. Both classes 2 and 3 are subdivided into classes a, b, and c, which represent the pancreatic tail, body, and head, respectively. In this report, 14 cases belonged to class 1, 10 belonged to class 2, and 11 belonged to class 3. Of the 14 patients with class 1 injuries, 10 underwent nonsurgical treatment and 4 underwent pancreatic duct stenting. Of the 10 patients with class 2 injuries, 4 underwent nonsurgical treatment and 6 underwent pancreatic duct stenting. Two of the 11 patients with class 3 injuries underwent pancreatic duct stenting; one in the acute stage developed sepsis that led to death even after converting to distal pancreatectomy plus splenectomy. Of the 11 patients with class 3 injuries, spleen-preserving distal pancreatectomy was performed in 6, distal pancreatectomy plus splenectomy in 2, and Roux-en-Y pancreaticojejunostomy after central pancreatectomy in 2. The overall pancreatic-related morbidity rate was 60% and the mortality rate was 2.8%.Conclusion: Based on our experience, class 1 and 2 injuries could be treated by nonsurgical means and pancreatic duct stenting could be an adjunctive therapy in class 2b and 2c injuries. Operation is warranted in class 3 injuries. [ABSTRACT FROM AUTHOR]

For ampullary cancer, pancreaticoduodenectomy is considered to be the standard treatment. Endoscopic papillectomy (EP) has been utilized in cases of ampullary adenoma since the early 1980s. We aimed to provide a review concerning EP. We conducted a review of studies regarding EP for ampullary neoplasms. Since neither lymphatic permeation, vascular invasion, nor lymph node metastasis is observed in patients with ampullary cancer limited to the mucosa, EP of such tumors without ductal infiltration into the pancreatic/bile duct can be justified as radical treatment. For its application in patients with ampullary neoplasms, accurate pretreatment staging is indispensable. EUS, which can be carried out on an outpatient basis with a low risk of complications, is useful for differential diagnosis as well as detection of periampullary tumors. Although intraductal US of the bile duct tends to result in overestimation of tumor staging in cases of ampullary neoplasm, it can provide useful information for making therapeutic decisions, especially in cases appropriate for EP. While the technical success rate of EP is high, the complication rate and recurrence rate are not as low as a satisfactory level. Pancreatic duct stenting after EP is expected to contribute to prevention of post-EP pancreatitis. There is no consensus regarding the mode of resection current nor the need for addition of biliary/pancreatic sphincterotomy and biliary stenting. EP has been reported to be useful in selected patients with ampullary neoplasms. Data on further long-term follow up after EP are awaited. [ABSTRACT FROM AUTHOR]
