Insights
Postoperative pancreatic fistula (POPF) Type C is linked to severe complications and mortality. Soft pancreatic consistency and high drain lipase activity on postoperative day 3 predict POPF Type C development.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Clinical Research
Background:
- The International Study Group of Pancreatic Fistula (ISGPF) classification aids POPF incidence and severity comparison.
- The ISGPF classification lacks post hoc guidance for individual POPF treatment.
- This study investigates POPF Types A-C's association with secondary surgical morbidity and mortality.
Purpose of the Study:
- To determine the impact of POPF Types A-C on secondary surgical morbidity and mortality.
- To identify predictors for the development of POPF Type C.
Main Methods:
- Analysis of 483 patients undergoing pancreatic resections between 3/2001-12/2007.
- Prospective data collection and classification of POPF according to ISGPF criteria.
- Statistical analysis of POPF association with surgical complications and mortality.
Main Results:
- POPF patients experienced significantly more vascular complications than non-POPF patients.
- POPF Type C was associated with significant surgical complications (17 vascular) and mortality (5/29).
- Soft pancreatic consistency (OR 8.5) and high drain lipase activity on postoperative day 3 (OR 4.4) predicted POPF Type C.
Conclusions:
- POPF Type C correlates with severe vascular complications, delayed gastric emptying, and pleural effusions.
- Soft pancreatic consistency and elevated postoperative day 3 drain lipase activity are early predictors of POPF Type C.
- Understanding these predictors can guide early intervention for POPF Type C.
Background:
The International Study Group of Pancreatic Fistula (ISGPF) classification allows comparison of incidence and severity of postoperative pancreatic fistula (POPF). Its post hoc character, however, does not provide a guideline for the treatment of POPF in individual patient. We therefore studied the association of POPF type A-C on secondary surgical morbidity and mortality in patients undergoing pancreatic resection.
Patients And Methods:
Between 3/2001-12/2007, 483 patients underwent pancreatic resections. POPF were classified according to the ISGPF classification. All patient data were entered in a clinical data management system prospectively.
Results:
Patients who developed POPF had significantly more vascular but not other surgical complications than patients without POPF. Patients with POPF A had no vascular or surgical complications. Twenty one of the 29 patients with POPF C had surgical complications (17 vascular complications). Mortality attributed to surgical complications after POPF C was 5/29. A soft pancreatic consistency (OR 8.5; p < 0.008) and a high drain lipase activity on postoperative day 3 (OR 4.4; p = 0,065) were predictors for the development of POPF C.
Discussion:
POPF C is associated with vascular complications like erosion bleeding and other surgical complications like delayed gastric emptying or pleural effusions. A soft pancreatic consistency and a high drain lipase activity on postoperative day 3 are early predictors for the development of POPF C.
