Duodenal obstruction from chronic pancreatitis

Area of Science:

• Gastroenterology
• Surgical Oncology

Background:

• Chronic pancreatitis can lead to fibrosclerosis, causing constriction of pancreatic and bile ducts, as well as the duodenum.
• Duodenal obstruction is a potential complication of chronic pancreatitis, presenting with symptoms like vomiting and large aspirate volumes.

Purpose of the Study:

• To analyze the outcomes of surgical interventions for duodenal obstruction in patients with chronic pancreatitis.
• To determine the most effective surgical procedures for relieving duodenal obstruction in this patient population.

Main Methods:

• Retrospective analysis of 24 patients diagnosed with duodenal obstruction secondary to chronic pancreatitis.
• Diagnostic methods included barium meal and endoscopic examination.
• Surgical procedures included gastrojejunostomy, vagotomy, gastroduodenostomy, Finney pyloroplasty, duodenoplasty, and Whipple procedure.

Main Results:

• Various surgical procedures were employed, with gastrojejunostomy and vagotomy being common interventions.
• Eight patients underwent gastrojejunostomy, and another eight had gastrojejunostomy with vagotomy.
• The Whipple procedure was performed in four patients, primarily for suspected malignancy or small duct chronic pancreatitis.

Conclusions:

• Vagotomy combined with gastroenterostomy is recommended as the primary surgical approach for duodenal obstruction in chronic pancreatitis.
• Bypass surgery effectively alleviates obstruction of the common bile duct and pancreatic duct.
• The Whipple procedure is indicated for small duct chronic pancreatitis or when malignancy is suspected.
