From the Research
Groove pancreatitis is a rare and clinically distinct form of chronic pancreatitis affecting the pancreaticoduodenal groove, comprising the head of the pancreas, duodenum, and the common bile duct, as described in the most recent and comprehensive review 1.
Definition and Prevalence
Groove pancreatitis (GP) is a rare form of chronic pancreatitis that specifically affects the "groove" area between the pancreatic head, duodenum, and common bile duct. It is more prevalent in individuals in their 4-5th decade of life and disproportionately affects men compared with women, with excessive alcohol consumption, tobacco smoking, pancreatic ductal stones, pancreatic divisum, annular pancreas, ectopic pancreas, duodenal wall thickening, and peptic ulcers being significant risk factors implicated in the development of GP 1.
Clinical Presentation
The usual presenting symptoms of GP include severe abdominal pain, nausea, vomiting, diarrhea, weight loss, and jaundice. Establishing a diagnosis of GP is often challenging due to significant clinical and radiological overlap with numerous benign and malignant conditions affecting the same anatomical location, which can lead to a delay in initiation of treatment, resulting in increasing morbidity, mortality, and complication rates 1.
Diagnosis and Management
Diagnosis involves imaging studies such as CT scans, MRI, or endoscopic ultrasound, which may show thickening of the duodenal wall and cystic changes in the groove area. Treatment initially focuses on conservative management, including alcohol cessation, pain control with medications, and nutritional support. In severe cases that don't respond to medical therapy, surgical intervention such as pancreaticoduodenectomy (Whipple procedure) may be necessary 1, 2.
Importance of Recognition
This condition is important to recognize because it can mimic pancreatic cancer, potentially leading to unnecessary radical surgery if misdiagnosed. Recent research in artificial intelligence (AI) has garnered immense interest in recent years, with the potential to become a vital tool in differentiating GP from pancreatic malignancies, thereby preventing a missed or delayed diagnosis 1.
Key Points
- GP is a rare form of chronic pancreatitis affecting the pancreaticoduodenal groove.
- It typically presents with symptoms of abdominal pain, weight loss, vomiting, and jaundice.
- Diagnosis involves imaging studies such as CT scans, MRI, or endoscopic ultrasound.
- Treatment initially focuses on conservative management, with surgical intervention in severe cases.
- Recognition of GP is crucial to avoid misdiagnosis and unnecessary radical surgery.
