Modified pancreaticoduodenectomy: experience with 81 cases, Wahab modification

Area of Science:

• Gastroenterology
• Surgical Oncology
• Hepatobiliary Surgery

Background:

• Pancreaticoduodenectomy is a standard treatment for periampullary tumors.
• Despite surgical advancements, high morbidity rates persist.
• Technical modifications aim to reduce complications associated with this procedure.

Purpose of the Study:

• To introduce and evaluate a modified pancreaticoduodenectomy technique.
• To decrease the incidence of morbidity and mortality in patients undergoing pancreaticoduodenectomy.
• To assess the safety and efficacy of the modified surgical approach.

Main Methods:

• A modified pancreaticoduodenectomy was performed on 81 patients between 1994-2000.
• The study included patients with various periampullary tumors, including pancreatic, ampullary, bile duct, and duodenal carcinomas.
• Data on operative time, blood loss, complications, and postoperative stay were collected.

Main Results:

• The modified procedure resulted in a hospital mortality rate of 3.7% and an overall morbidity rate of 32%.
• Common complications included delayed gastric emptying (8.9%), wound infection (6.4%), and pancreatic fistulae (3.8%).
• Mean operative time was 3.7 hours with an average blood loss of 733 mL; mean hospital stay was 9.4 days.

Conclusions:

• The modified pancreaticoduodenectomy simplifies the procedure, reduces operative time, and minimizes blood transfusion requirements.
• This technique leads to a lower incidence of complications such as biliary gastritis, cholangitis, and peptic ulcers.
• The modified approach offers a safer and more effective treatment option for periampullary tumors, with reduced morbidity and shorter hospital stays.
