Prophylactic abdominal drainage for pancreatic surgery.

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Evidence-Based Medicine

Background:

• Prophylactic abdominal drainage after pancreatic surgery is common but its benefit in reducing postoperative complications remains controversial.
• This review is an update of a previous Cochrane Review examining the uncertain benefits of prophylactic abdominal drainage in pancreatic surgery.

Purpose of the Study:

• To assess the benefits and harms of routine abdominal drainage post-pancreatic surgery.
• To compare different types of surgical drains.
• To evaluate the optimal timing for drain removal.

Main Methods:

• Inclusion of all randomized controlled trials (RCTs) comparing abdominal drainage versus no drainage, different drain types, and drain removal schedules.
• Data extraction and risk of bias assessment by two independent reviewers.
• Meta-analyses using Review Manager 5 with random-effects models and GRADE assessment for evidence certainty.

Main Results:

• Low-certainty evidence suggests drain use may reduce 90-day mortality but shows little to no difference in 30-day mortality, wound infection, length of stay, or quality of life compared to no drainage.
• Moderate-certainty evidence indicates drain use likely results in little to no difference in overall morbidity.
• Evidence is very uncertain regarding active versus passive drains and the effects of early versus late drain removal on various outcomes, although early removal may reduce intra-abdominal infections, morbidity, and hospital stay in low-risk patients.

Conclusions:

• The effect of routine drain use on 30-day mortality and complications after pancreatic surgery remains unclear.
• Low-certainty evidence suggests routine drain use may reduce 90-day mortality.
• Early drain removal may offer benefits for specific outcomes in low-risk patients, but the evidence is highly uncertain.
