“… 6 DDC are usually filled with clear fluid, but can contain bile, pancreatic fluid, or gallstones if they connect to the pancreaticobiliary ducts. 12 – 15 DDC can occur in any duodenal segment, but most commonly arise in the second or third parts of the duodenum. They usually arise on the mesenteric side.…”

“… 4 The most common complication is acute pancreatitis. 4 , 12 Other complications include: jaundice, biliary obstruction, cyst infection, intussusception, cholestasis, and hepatitis. 4 , 14 – 20 DDC may contain ectopic pancreatic or gastric tissue that can cause duodenal ulcers, gastrointestinal (GI) bleeding, or rarely duodenal perforation.…”

“…DDC are strongly suggested by characteristic radiologic imaging findings, but imaging findings are occasionally misleading. 12 , 18 Twin major goals of radiologic imaging are to determine that the lesion is fluid-filled and to locate the cyst attachment site. 13 Contrast radiographs reveal a submucosal or extrinsic mass or filling defect.…”

Analyze efficacy, safety of endoscopic therapy for duodenal duplication cysts (DDC) by comprehensively reviewing case reports.Tandem, independent, systematic, computerized, literature searches were performed via PubMed using medical subject headings or Keywords “cyst” and “duodenal” and “duplication”; or “cyst”, and “endoscopy” or “endoscopic”, and “therapy” or “decompression”; with reconciliation of generated references by two experts. Case report followed CARE guidelines.Literature review revealed 28 cases (mean = 1.3 ± 1.2 cases/report). Endoscopic therapy is increasingly reported recently (1984–1999: 3 cases, 2000–2015: 25 cases, P = 0.003, OR = 8.33, 95%-CI: 1.77–44.5). Fourteen (54%) of 26 patients were men (unknown-sex = 2). Mean age = 32.2 ± 18.3 years old. Procedure indications: acute pancreatitis-16, abdominal pain-8, jaundice-2, gastrointestinal (GI) obstruction-1, asymptomatic cyst-1. Mean maximal DDC dimension = 3.20 ± 1.53 cm (range, 1–6.5 cm). Endoscopic techniques included cyst puncture via needle knife papillotomy (NKP)/papillotome-18, snare resection of cyst-7, cystotome-2, and cyst needle aspiration/ligation-1. Endoscopic therapy was successful in all cases. Among 24 initially symptomatic patients, all remained asymptomatic post-therapy without relapses (mean follow-up = 36.5 ± 48.6 months, 3 others reported asymptomatic at follow-up of unknown duration; 1 initially asymptomatic patient remained asymptomatic 3 years post-therapy). Two complications occurred: mild intraprocedural duodenal bleeding related to NKP and treated locally endoscopically.A patient is reported who presented with vomiting, 15-kg-weight-loss, and profound dehydration for 1 month from extrinsic compression of duodenum by 14 × 6 cm DDC, underwent successful endosonographic cyst decompression with large fenestration of cyst and endoscopic aspiration of 1 L of fluid from cyst with rapid relief of symptoms. At endoscopy the DDC was intubated and visualized and random endoscopic mucosal biopsies were obtained to help exclude malignant or dysplastic DDC.Study limitations include retrospective literature review, potential reporting bias, limited patient number, variable follow-up.In conclusion, endoscopic therapy for DDC was efficacious in all 29 reported patients including current case, including patients presenting acutely with acute pancreatitis, or GI obstruction. Complications were rare and minor, suggesting that endoscopic therapy may be a useful alternative to surgery for nonmalignant DDC when performed by expert endoscopists.
