Introduction

Due to improvements in endoscopic techniques, the opportunity to perform endoscopic submucosal dissection (ESD) for periampullary adenoma has gradually increased. However, it remains a challenging procedure even in high-volume centers. The duodenum’s anatomical characteristics, such as the fixed position to the retroperitoneum, tortuous lumen, thin duodenal wall, and rich Brunner’s glands in the submucosa, make ESD difficult. Additionally, exposure to bile or pancreatic fluid may increase the risk of delayed bleeding and perforation. In clinical practice, the incidence of perforation and bleeding is reportedly 13% to 50% and 20%, respectively.1

Biliary self-expandable metallic stent (SEMS), pancreatic stent deployment after endoscopic papillectomy,2 and endoscopic naso-pancreatic drain placement after ESD involving the papilla have been reported as preventive strategies for postprocedural adverse events.3 Here, we report a case in which simultaneous bile duct injury and duodenal perforation were successfully managed by placing a SEMS and naso-pancreatic drain.

Case

An asymptomatic 56-year-old male patient presented with a large periampullary lesion and was referred to our center for endoscopic treatment. Workup endoscopy revealed a 50-mm, flat, elevated lesion located in the second portion on the oral side of the papilla (Fig. 1). The preoperative diagnosis was an adenoma, and we adopted ESD for safety, to secure en bloc resection, and for accurate pathologic diagnosis.4 ESD was performed using a DualKnifeJ (Olympus, Tokyo, Japan) with the water pressure method5 with the patient under conscious sedation (Fig. 2A). Although this was technically challenging because of the narrow submucosal space to dissect due to rich Brunner’s glands, en bloc resection was achieved in 146 minutes (Fig. 2C). The resected tumor was 49 × 37 mm in size, with pathologic findings of low-grade tubular adenoma (Figs. 3 and 4). During the procedure, extensive bile juice leakage was observed (Fig. 2B); therefore, we carefully observed the wound using a side-viewing endoscopy. Consequently, the accidental bile duct disconnection with a retroperitoneal perforation on the dorsal side near the sphincter of Oddi was confirmed (Fig. 5A).Figure 1. Workup endoscopic images.

The transection surface of the bile duct was relatively large to place a naso-biliary drain tube. Subsequently, we deployed a fully covered SEMS for the bile duct in preference to suturing the wound and a naso-pancreatic drain for the pancreatic duct after the insertion of guidewires into the biliary and pancreatic ducts (Fig. 5B).6 The patient experienced mild peritonitis with retroperitoneal perforation after the procedure, and the volume of naso-pancreatic drainage was adequate at approximately 200 mL daily without suction. He was treated conservatively with the backup of surgery, the infusion of antibiotics, proton pump inhibitor (20 mg of omeprazole daily), octreotide, and fasting for 8 days. Follow-up esophagastroduodenoscopy on postoperative day 8 showed that the post-ESD ulcer had shrunk, and the perforation had completely closed. After confirming the absence of retroperitoneal leakage of contrast medium, the SEMS and naso-pancreatic drain were removed (Fig. 6). Finally, the patient was discharged without any subsequent adverse events after a 12-day postoperative hospitalization (Video 1, available online at www.videogie.org).Figure 6.

Conclusion

The endoscopic treatment of periampullary adenoma close to ampullary lesions remains challenging. Although bile duct injury during ESD is a rare adverse event of ESD, extreme caution is required, particularly when resecting lesions located on the oral side of the papilla. Therefore, surgical intervention can be avoided by completely isolating the perforated site and pancreatic juice using a naso-pancreatic drain and compressing the perforated site by deploying a fully covered SEMS.
