Groove pancreatitis (GP) is a rare condition affecting the pancreatic groove region within the dorsal-cranial part of the pancreatic head, duodenum, and common bile duct. As a rare form of chronic pancreatitis, GP poses a diagnostic and therapeutic challenge for clinicians. GP is frequently misdiagnosed or not considered; thus, the diagnosis is often delayed by weeks or months. The treatment of GP is complicated and often requires surgical intervention, especially pancreatoduodenectomy.
A 66-year-old man with a history of long-term drinking was admitted to the gastroenterology department of our hospital, complaining of vomiting and acid reflux. Upper gastrointestinal endoscopy showed luminal stenosis in the desce
GP often involves the descending and horizontal parts of the duodenum and causes duodenal stenosis, impaired duodenal motility, and gastric emptying due to fibrosis.
Core Tip: Groove pancreatitis (GP) is an uncommon form of chronic pancreatitis affecting the pancreatic groove region. In this case study, upper gastrointestinal endoscopy showed duodenal stenosis and abdominal computed tomography showed probable local pancreatitis. The symptoms of intestinal obstruction were not relieved with conservative therapy. Exploratory laparoscopy revealed a hard mass with scarring in the horizontal part of the duodenum and stenosis. Duodenojejunostomy was performed and routine pathologic examination of the mass biopsy showed extensive proliferation of fibrous tissue, indicating GP. Despite surgical therapy, the patient presented with anastomotic obstruction postoperatively and took a long time to recover.
