Acute Pancreatitis with an Ongoing Pancreatic Duct Leak Complicated by Refractory Pleural Effusion: A Case Report

PREDICTION OF EXTERNAL PANCREATIC FISTULA DEVELOPMENT IN PATIENTS WITH ACUTE INFECTED NECROTISING PANCREATITIS

OBJECTIVE

The aim: To search for risk factors for the development of external pancreatic fistula (EPF) in patients with acute infected necrotizing pancreatitis.

PATIENTS AND METHODS

Materials and methods: A prospective single-center observational study was conducted with the participation of 160 adult patients with infected acute necrotizing pancreatitis (ANP) who required intervention at different stages of the disease. Depending on the amylase activity of the drainage secretions, the groups with and without diagnosed EPF were compared according to 15 demographic, clinical, laboratory and instrumental parameters of the disease. To identify predictors of the risk of developing EPF in ANP, a regression logistic analysis was performed and logistic regression models were built for each factor attribute.

RESULTS

Results: We did not find statistically significant differences in the indicators characterising patients on the first day of illness, as well as in the comparison of indicators characterising local complications of AP, the timing of AP infection, the incidence of sepsis and the level of PON in sepsis. When comparing the groups by the frequency of the type of microbial agent of infected APB, no statistically significant differences were found. Comparative pairwise analysis between the groups by morphological characteristics revealed statistical differences in the frequency of focal superficial and transmural PN (p < 0.001). Next, we performed a regression logistic analysis and built logistic regression models for each factor attribute, namely age, gender, BMI, BISAP score and Charlson comorbidity index, morphological characteristics of necrotizing pancreatitis. After univariate regression analysis, a statistically significant association between the depth of PN and the risk of developing PFN was found (OR 2.7 (1.4-5.2), p=0.001).

CONCLUSION

Conclusions: We found that the risk of developing an external pancreatic fistula was associated with the depth of pancreatic necrosis.

Black Pleural Effusion as a Complication of Acute Pancreatitis

Transient and reactive pleural effusion is a known consequence of acute pancreatitis. Usually, the pleural effusion is unilateral, transudate, straw-colored, and self-resolving. We report a rare case of massive left-sided black pleural effusion as a complication of acute pancreatitis with the background of chronic pancreatitis being secondary to alcohol abuse. The pleural effusion resulted in hypoxic respiratory failure. However, the patient had significant improvement after drainage of the pleural effusion and the appropriate management of sepsis with broad-spectrum antibiotics. The patient had a significant improvement and recovery with conservative management without the need for endoscopic therapy or surgical intervention.
