Incidence of necrotizing pancreatitis and factors related to mortality
Abstract:
Of 348 cases of acute pancreatitis presenting between 1980 and 1985, extensive retroperitoneal necrosis with bacterial or fungal superinfection developed in only 17 (4.8 percent). However, in 14 of the 17 patients (80 percent), multiple surgical interventions and intensive supportive therapy failed to control the process, and they died from complications. Deaths occurred after a prolonged in-hospital course characterized by sequential failure of organ systems. If the salvage of these patients is to be optimized, as in some reports, the timing of the first surgical procedure has to be very carefully made based on the clinical and laboratory findings, and most importantly, the results of computerized tomography. Exploration is probably best carried out through an extended subcostal incision, and a determined attempt must be made to remove all of the necrotic tissue. Little reliance can be placed on the possibility that significant amounts of residual necrotic tissue can be aspirated through sump catheters or evacuated by irrigations. We believe that the poor results in this series lend strong support to those who have already advocated much more universal application of the open abdomen technique in the management of these patients with widespread anterior pararenal space necrosis.
Insights
Extensive retroperitoneal necrosis in acute pancreatitis is rare but often fatal. Early, precise surgical intervention guided by imaging is crucial for patient survival.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Infectious Diseases
Background:
- Acute pancreatitis can lead to severe retroperitoneal necrosis.
- Superinfection of necrotic tissue significantly increases mortality.
- Previous management strategies have shown limited success.
Purpose of the Study:
- To evaluate the outcomes of patients with extensive retroperitoneal necrosis secondary to acute pancreatitis.
- To identify factors influencing survival in these critically ill patients.
- To assess the efficacy of surgical interventions and supportive care.
Main Methods:
- Retrospective analysis of 348 acute pancreatitis cases from 1980-1985.
- Identification of patients with extensive retroperitoneal necrosis and superinfection.
- Review of treatment modalities, including surgical interventions and supportive therapy.
- Correlation of clinical, laboratory, and imaging findings with patient outcomes.
Main Results:
- Only 4.8% of acute pancreatitis cases developed extensive retroperitoneal necrosis with superinfection.
- 80% of these patients (14 out of 17) died despite multiple surgeries and intensive care.
- Deaths resulted from prolonged hospital stays and sequential organ system failure.
- Computed tomography (CT) findings were critical for surgical timing and planning.
Conclusions:
- Extensive retroperitoneal necrosis with superinfection in acute pancreatitis carries a very high mortality rate.
- Careful timing of surgical exploration, guided by clinical, laboratory, and CT findings, is essential.
- Complete removal of necrotic tissue via open surgery is recommended over less invasive methods.
- The open abdomen technique may be beneficial for widespread necrosis in the anterior pararenal space.
