Introduction:
This article describes a case series outlining the experience and results of the retroperitoneal minimally invasive pancreatic necrosectomy (MIPN) procedure performed by, or done under the supervision of, a single surgeon.
Methods:
All data of the patients who underwent MIPN from 2006 to 2008 were entered into a prospectively maintained, computerized database.
Results:
A total of 93 MIPN procedures were performed on 32 patients. All patients had severe acute pancreatitis. The median number of MIPN procedures per patient was 3. Only 6 patients needed intensive care unit (ICU) admission after MIPN. There were 15 complications, which included bleeding requiring transfusion (n = 3), bowel fistulae (n = 7), thromboembolic events (n = 2) and acute myocardial infarction (n = 3). Four patients died after the procedure (13%); 1 died of ongoing multiorgan failure in spite of the MIPN. Four patients developed pancreatic pseudocysts within the follow-up period of 2 years. Three of these patients required intervention.
Conclusion:
This case series demonstrates that MIPN can be performed with acceptable morbidity and mortality and with good end results. The ICU dependency after the procedure is minimal. As seen in this series, multiple MIPNs may be needed to eradicate the necrosis satisfactorily. and IAP.
Insights
Minimally invasive pancreatic necrosectomy (MIPN) offers good outcomes for severe acute pancreatitis. This case series shows acceptable morbidity and mortality, with minimal intensive care unit (ICU) dependency, though multiple procedures may be necessary.
Area of Science:
- Gastroenterology
- Surgical Innovation
Background:
- Severe acute pancreatitis necessitates effective treatment strategies.
- Minimally invasive pancreatic necrosectomy (MIPN) is an evolving surgical approach.
- This study focuses on a single surgeon's experience with retroperitoneal MIPN.
Purpose of the Study:
- To evaluate the outcomes of retroperitoneal minimally invasive pancreatic necrosectomy (MIPN).
- To assess the safety, efficacy, and complication rates of MIPN.
- To report on the long-term results of MIPN in patients with severe acute pancreatitis.
Main Methods:
- A case series of 32 patients undergoing retroperitoneal MIPN from 2006 to 2008.
- Data collected prospectively in a computerized database.
- Analysis of procedure count, complications, and outcomes.
Main Results:
- 93 MIPN procedures were performed on 32 patients with severe acute pancreatitis.
- Median of 3 MIPN procedures per patient.
- 15 complications occurred, including bleeding, bowel fistulae, and thromboembolic events. Mortality was 13% (4 patients).
- 4 patients developed pseudocysts requiring intervention within 2 years.
Conclusions:
- Retroperitoneal MIPN can be performed with acceptable morbidity and mortality.
- Good end results were achieved with MIPN.
- Multiple MIPN procedures may be required for satisfactory necrosis eradication.
