Endoscopic closure techniques have been introduced for the repair of duodenal wall perforations that occur during endoscopic retrograde cholangiopancreatography (ERCP). We report a case of successful repair of a large duodenal wall perforation by using double endoscopic band ligation (EBL) and an endoclip. Lateral duodenal wall perforation occurred during ERCP in a 93-year-old woman with acute calculous cholangitis. We switched to a forward endoscope that had a transparent band apparatus. A 2.0-cm oval-shaped perforation was found at the lateral duodenal wall. We repaired the perforation by sequentially performing double EBL and endoclipping. The first EBL was performed at the proximal edge of the perforation orifice, and two-thirds of the perforation were repaired. The second EBL, which also included the contents covered under the first EBL, repaired the defect almost completely. Finally, to account for the possible presence of a residual perforation, an endoclip was applied at the distal end of the perforation. The detection and closure of the perforation were completed within 10 minutes. We suggest that double EBL is an effective method for closure.

Branch duct intraductal papillary mucinous neoplasms of the pancreas (BD-IPMN) without malignant features rarely developed into invasive cancer. However, invasive cancer is aggressive once an invasive change occurs. We report three cases of invasive cancers which developed in patients with BD-IPMN and they showed grave clinical courses. All patients were diagnosed with BD-IPMN < 3 cm without malignant features on imaging. Invasive cancer was detected at 2.5 years, 3.0 years, and 4.0 years after BD-IPMN detection in each patient. The intervals of invasive cancer and the last follow-up were 9 months, 3 years, and 1.5 years in the three patients, respectively. All patients were diagnosed with locally advanced pancreas invasive cancers and were treated with palliative chemotherapy or conservative management. The patients died at 3 months, 9 months, and 10 months after the diagnosis of invasive cancers, respectively. We report three cases of invasive cancer developed in BD-IPMN patients and followed fatal courses.

Peptic ulcer bleeding is treated using endoscopic hemostasis using clips or bands. Pancreas divisum (PD), a congenital anomaly of the pancreas, usually has no clinical symptoms; however, pancreatitis may occur if there are disturbances in the drainage of pancreatic secretions. We report an unusual case of PD accompanied by acute pancreatitis, following endoscopic band ligation for duodenal ulcer bleeding. A 48-year-old woman was admitted to our hospital due to melena. An upper endoscopy revealed a small ulcer with oozing adjacent minor papilla. An endoscopic band ligation was performed on this lesion. Acute pancreatitis developed suddenly 6 hours after the band ligation and improved dramatically after removal of the band. Magnetic resonance cholangiopancreatography was performed, revealing complete PD. Endoscopic band ligation is known as the effective method for peptic ulcer bleeding; however, it should be used carefully in duodenal ulcer bleeding near the minor duodenal papilla due to the possibility of PD.

A nasal-type extranodal natural killer/T-cell lymphoma is considered an aggressive form of non-Hodgkin's lymphoma, with approximately half of all patients relapsing during the follow-up period, and most relapses occurring within the first 2 years of remission. Here we report an unusual case of a 42-year-old man who experienced recurrence in single pleura after 8 years of remission.
