Double Common Bile Duct with Ectopic Drainage into the Stomach Found in Asymptomatic.

The case of a patient with asymptomatic double common bile duct that was identified by chance is presented. A 41-year-old man underwent esophagogastroduodenoscopy(EGD) as part of a regular health checkup, during which he was found to have an elevated lesion in the lesser curvature of the upper gastric corpus with bile draining from its tip. Further examination led to a diagnosis of double common bile duct from the left intrahepatic bile duct to the opening into the stomach. Morphological abnormalities of the biliary tree are commonly encountered in everyday gastroenterological practice, but a double common bile duct with an ectopic opening into the stomach is comparatively rare. It is also associated with an increased risk of developing cancer of the stomach or bile duct, and as such is a biliary abnormality that must be treated with caution. This case is reported together with a discussion of the literature.

Successful Eradication Therapy for Helicobacter pylori-positive Atrophic Gastritis at the Sixth Attempt: A Case Report.

A 74-year-old woman undergoing outpatient follow-up for reflux esophagitis and atrophic gastritis tested positive for Helicobacter pylori and underwent primary eradication therapy with lansoprazole (LPZ) 30 mg, amoxicillin (AMPC) 750 mg, and clarithromycin (CAM) 200 mg twice daily for 1 week in August 2012. A urea breath test (UBT) after this treatment revealed that eradication had failed. Secondary eradication therapy was carried out with esomeprazole (EPZ) 20 mg, AMPC 750 mg, and metronidazole (MNZ) 250 mg twice daily for 1 week, but this also failed. The third attempt at eradication consisted of EPZ 20 mg, AMPC 750 mg, and sitafloxacin (STFX) 100 mg twice daily for 1 week, but this also ended in failure. A fourth attempt using rabeprazole (RPZ) 20 mg (4 times daily) with MNZ 250 mg and STFX 100 mg twice daily for 2 weeks also failed, as did a fifth attempt in April 2015 using vonoprazan (VPZ) 20 mg, AMPC 750 mg, and MNZ 250 mg twice daily for 1 week. Eradication was finally successful after the sixth attempt, in which the patient was treated with vonoprazan 20 mg, MNZ 250 mg, and STFX 100 mg twice daily for 2 weeks.

Fatal Hemorrhagic Gastrointestinal Angioectasia after Bone Marrow Transplantation for Dyskeratosis Congenita.

Dyskeratosis congenita (DC) is a rare inherited disease in which the telomere complex cannot be maintained. Shortened telomeres can cause a number of clinical conditions. We herein report a case of unrelated bone marrow transplantation due to aplastic anemia associated with DC. The patient died of uncontrollable refractory intestinal bleeding. Three cases of DC with life-threatening hemorrhaging after transplantation have been reported; however, the bleeding origin could not be determined. Our case is the only patient in which a gastrointestinal bleeding point, jejunal multiple angioectasia, was determined.

Successful Endoscopic Resection in a Case of Ectopic and Metachronous Quintuple Gastric Cancers.

A 71-year-old man was referred to us from another hospital for endoscopic treatment of a IIc lesion at the anterior wall of the lower body of the stomach. In November 2008, he underwent resection of this lesion with endoscopic submucosal dissection (ESD). Follow-up endoscopy revealed a IIc lesion in the posterior wall of the lower body of the stomach, and ESD was again performed in February 2009. At the same time, Helicobacter pylori was detected, and successful first-line eradication therapy was verified in May 2009. Subsequent follow-up endoscopy detected multiple ectopic and metachronous gastric cancers at three sites, all of which were endoscopically resected (quintuple gastric cancer). Although ectopic and metachronous recurrence of gastric cancer was detected immediately after H. pylori eradication, recurrence of gastric cancer has not been detected in the 5 years since eradication. Future directions include determining the time point at which the preventative effects of H. pylori eradication therapy appear against gastric cancer recurrence. We report our findings herein, along with a review of the related literature.
