Abstract
Per-oral pancreatoscopy (POP) is a pancreas-preserving modality that allows for targeted pancreatic duct interventions, particularly in cases where standard techniques fail. POP specifically has an emerging role in the diagnosis, risk stratification, and disease extent determination of main duct intraductal papillary mucinous neoplasms (IPMNs). It has also been successfully used for laser ablation of IPMNs in poor surgical candidates, lithotripsy for complex stone disease, and laser stricturoplasty. As experience with POP increases beyond select referral center practices, further studies validating POP efficacy with long-term follow-up will help clarify when POP-guided intervention is most beneficial in relation to surgical intervention.

GASTROENTEROLOGIA Y HEPATOLOGIA 2024; 47:170-178. [PMID: 37301507 DOI: 10.1016/j.gastrohep.2023.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 05/19/2023] [Accepted: 06/01/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND AND STUDY AIMS The single-operator cholangiopancreatoscopy (SOCP) with the SpyGlass™ system is a endoscopy technique whose use has grown exponentially in recent years. The aims of this study were to evaluate the efficacy and safety of SOCP with SpyGlass™ and determine the factors related to the onset of adverse events (AEs). PATIENTS AND METHODS Retrospective study at a single tertiary institution with inclusion of all consecutive patients undergoing SOCP with SpyGlass™ from February-2009 to December-2021. No exclusion criteria were considered. A descriptive statistical analysis was performed. The factors associated with the existence of AE were analyzed using Chi-square and Student's t-test. RESULTS A total of 95 cases were included. The most common indications were biliary strictures (BS) evaluation (66.3%) or treatment of difficult common bile duct stones (27.4%). Technical and clinical success was attained in 98.9%. Single-session stone clearance was obtained in 84%. The AE rate was 7.4%. To detect malignancy in BS, optical diagnosis presents a sensitivity and specificity of 100% and 91.2%, respectively; while histology results were 36.4% and 100% respectively. A previous endoscopic sphincterotomy was associated with a lower rate of AEs (2.4% vs 41.7%; p<0.001). CONCLUSIONS SOCP with SpyGlass™ is a safe and effective technique to diagnose and treat pancreatobiliary pathology. The presence of sphincterotomy performed prior to the procedure could improve the technique's safety.

Abstract
Intraductal papillary mucinous neoplasm (IPMN) is a premalignant lesion of the pancreas that can occasionally manifest as recurrent acute pancreatitis. In this report, we discuss a unique case of a 49-year-old woman who presented with recurrent acute pancreatitis of an unknown cause for several years. Workup using peroral pancreatoscopy eventually showed main-duct IPMN with high-grade dysplasia as the obscure cause of recurrent acute pancreatitis. This case report highlights the clinical course of main-duct IPMN and the evolving role of peroral pancreatoscopy in patients with recurrent acute pancreatitis.

Abstract
Pancreatoscopy plays a significant role in the diagnosis and treatment of pancreatic diseases. However, the risk of pancreatoscopy is remarkably greater than that of other endoscopic procedures, such as gastroscopy and bronchoscopy, owing to its severe invasiveness. In comparison, virtual pancreatoscopy (VP) has shown notable advantages. However, because of the low resolution of current computed tomography (CT) technology and the small diameter of the pancreatic duct, VP has limited clinical use. In this study, an optimal path algorithm and super-resolution technique are investigated for the development of an open-source software platform for VP based on 3D Slicer. The proposed segmentation of the pancreatic duct from the abdominal CT images reached an average Dice coefficient of 0.85 with a standard deviation of 0.04. Owing to the excellent segmentation performance, a fly-through visualization of both the inside and outside of the duct was successfully reconstructed, thereby demonstrating the feasibility of VP. In addition, a quantitative analysis of the wall thickness and topology of the duct provides more insight into pancreatic diseases than a fly-through visualization. The entire VP system developed in this study is available at https://github.com/gaoyi/VirtualEndoscopy.git.

Peroral Pancreatoscopy with Videoscopy and Narrow-Band Imaging in Intraductal Papillary Mucinous Neoplasms with Dilatation of the Main Pancreatic Duct. Clin Endosc 2021; 55:270-278. [PMID: 34865339 PMCID: PMC8995986 DOI: 10.5946/ce.2021.083] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Accepted: 07/27/2021] [Indexed: 12/02/2022] Open
Abstract
Background/Aims Endoscopic evaluation of intraductal papillary mucinous neoplasms (IPMNs) is useful in determining whether the lesions are benign or malignant. This study aimed to examine the usefulness of peroral pancreatoscopy (POPS) in determining the prognosis of IPMNs.
Methods POPS with videoscopy was performed using the mother–baby scope technique. After surgery, computed tomography/magnetic resonance cholangiopancreatography or ultrasonography and blood tests were performed every 6 months during the follow-up.
Results A total of 39 patients with main pancreatic duct (MPD)–type IPMNs underwent POPS using a videoscope, and the protrusions in the MPD were observed in 36 patients. The sensitivity and specificity of cytology/biopsy performed at the time of POPS were 85% and 87.5%, respectively. Of 19 patients who underwent surgery, 18 (95%) patients had negative surgical margins and 1 (5%) patient had a positive margin.
Conclusions In IPMNs with dilatation of the MPD, POPS is considered effective if the lesions can be directly observed. The diagnosis of benign and malignant lesions is possible depending on the degree of lesion elevation. However, in some cases, slightly elevated lesions may increase in size during the follow-up or multiple lesions may be simultaneously present; therefore, careful follow-up is necessary.

Abstract
OBJECTIVES Per oral pancreatoscopy (POP) assists in the evaluation and treatment of select benign and neoplastic pancreatic disorders including main-duct intraductal papillary mucinous neoplasm (MD-IPMN). Although pancreatic duct stones are classically thought of as pathognomonic for chronic pancreatitis, its co-occurrence with MD-IPMN as identified via POP may help identify an alternative etiology for presumed idiopathic chronic pancreatitis. METHODS This was a multicenter retrospective case series of patients found to have pancreatic duct stones with concomitant MD-IPMN by POP. RESULTS Thirteen patients with presumed idiopathic chronic calcific pancreatitis were found on POP to have both pancreatic duct stones and MD-IPMN. All patients had a dilated pancreatic duct, and most (92.3%) were symptomatic. CONCLUSIONS Per-oral pancreatoscopy may identify MD-IPMN as an etiology for patients with presumed idiopathic chronic calcific pancreatitis and associated dilated pancreatic duct. Larger prospective studies are needed to validate these findings.

Abstract
BACKGROUND AND AIMS The role of per-oral pancreatoscopy (POP) in the evaluation of occult pancreatic duct (PD) lesions remains limited to case series. The aim of this study was to evaluate the ability of POP to differentiate malignant from benign diseases of the PD. METHODS Patients who underwent POP between 2000 and 2013 for the evaluation of indeterminate PD strictures, dilatations, or with suspected or known main duct intraductal papillary mucinous neoplasm were identified. Main outcome measurements were visual impression accuracy, POP tissue sampling, efficacy, and safety of POP. RESULTS During the study period, 79 patients who underwent POP for the evaluation of pancreatic stricture or dilatation were identified. Technical success was achieved in 78 (97%). In the PD neoplasia group (n = 33), the final diagnosis was based on index confirmatory POP-guided tissue sampling in 29 (88%). For the detection of PD neoplasia, POP visual impression had a sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 87%, 86%, 83%, 91%, and 87%, respectively. When combined with POP-guided tissue sampling, the values were 91%, 95%, 94%, 93%, and 94%, respectively. Of 102 POPs performed, adverse events were noted in 12 (12%) cases. CONCLUSIONS This study demonstrates a high technical success rate, visual impression accuracy, and tissue sampling capability of POP. Examinations were performed by endoscopists with expertise in pancreatoscopy interpretation, and the results may not be generalizable.

Abstract
Cholangioscopy was first performed in the 1970s. We now use the term cholangiopancreatoscopy (CP) to reflect the wider application of these miniature reusable dual-operator "mother-daughter" endoscope systems and now fully disposable and digital single-operator optical catheters for evaluating the biliary or pancreatic duct. Cholangioscopy is an established modality for the management of large biliary stones and for the diagnosis and exclusion of biliary tumors. Pancreatoscopy is increasingly being performed to treat difficult pancreatic duct stones and may be used to distinguish malignant from benign ductal pathology. This review covers available CP technologies, indications, technique, efficacy, and complications.

Abstract
AIM: To provide consensus statements on the use of per-oral cholangiopancreatoscopy (POCPS).
METHODS: A workgroup of experts in endoscopic retrograde cholangiopancreatography (ERCP), endosonography, and POCPS generated consensus statements summarizing the utility of POCPS in pancreaticobiliary disease. Recommendation grades used validated evidence ratings of publications from an extensive literature review.
RESULTS: Six consensus statements were generated: (1) POCPS is now an important additional tool during ERCP; (2) in patients with indeterminate biliary strictures, POCS and POCS-guided targeted biopsy are useful for establishing a definitive diagnosis; (3) POCS and POCS-guided lithotripsy are recommended for treatment of difficult common bile duct stones when standard techniques fail; (4) in patients with main duct intraductal papillary mucinous neoplasms (IPMN) POPS may be used to assess extent of tumor to assist surgical resection; (5) in difficult pancreatic ductal stones, POPS-guided lithotripsy may be useful in fragmentation and extraction of stones; and (6) additional indications for POCPS include selective guidewire placement, unexplained hemobilia, assessing intraductal biliary ablation therapy, and extracting migrated stents.
CONCLUSION: POCPS is important in association with ERCP, particularly for diagnosis of indeterminate biliary strictures and for intra-ductal lithotripsy when other techniques failed, and may be useful for pre-operative assessment of extent of main duct IPMN, for extraction of difficult pancreatic stones, and for unusual indications involving selective guidewire placement, assessing unexplained hemobilia or intraductal biliary ablation therapy, and extracting migrated stents.
