Introduction:
In 1994, Claudio Bassi reported a case of medical treatment for infected pancreatic necrosis (IPN); then since 1996 numerous articles of case series were published with treatment only with antibiotics with good outcomes.
Objectives:
To present our experience in the management of patients with IPN with antibiotics (without drainage).
Methods:
We retrospectively reviewed cases with a diagnosis of IPN from January 2018 to October 2020, focusing on those cases that were treated conservatively (hydro-electrolyte, nutritional support and antibiotics). The diagnosis was made by observing gas in the retroperitoneum by CT or by clinical deterioration of the patient with pancreatic necrosis without another focus. Fine needle aspiration was not performed.
Results:
We identified 25 patients with a diagnosis of IPN; eleven were treated conservatively. According to Atlanta, modified in 2012, 3 were classified severely and the rest moderately severe. All received antibiotics for at least 3 weeks. None required parenteral nutrition. The mean hospital stay was 38 days. Three patients were readmitted. 8 underwent cholecystectomy after having resolved the condition; the rest were already cholecystectomized. There were no deaths in this series.
Conclusions:
IPN can be treated conservatively without drainage with good results in selected cases.
Insights
Conservative antibiotic treatment for infected pancreatic necrosis (IPN) shows good outcomes in selected patients. This approach avoids invasive drainage procedures, simplifying management and improving patient recovery.
Area of Science:
- Gastroenterology
- Surgical Infections
- Pancreatic Diseases
Background:
- Infected pancreatic necrosis (IPN) management has evolved since initial case reports.
- Antibiotic-only treatment for IPN has demonstrated positive outcomes in prior case series.
- Conservative approaches are increasingly explored for IPN management.
Observation:
- This study reviewed 25 patients diagnosed with IPN between January 2018 and October 2020.
- Eleven patients received conservative management, including antibiotics, hydration, and nutritional support.
- Diagnosis relied on CT findings of retroperitoneal gas or clinical deterioration without other infection sources.
Findings:
- All eleven conservatively treated patients received antibiotics for over three weeks.
- No patients required parenteral nutrition, and the average hospital stay was 38 days.
- Three patients were readmitted, and eight underwent cholecystectomy post-recovery; no mortality was observed.
Implications:
- Selected cases of IPN can be effectively managed conservatively with antibiotics alone.
- Non-operative management of IPN may reduce the need for invasive drainage procedures.
- This strategy offers a viable alternative, potentially improving patient outcomes and resource utilization.

For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
