Enzymatic debridement in necrotizing pancreatitis

Area of Science:

• Gastroenterology
• Surgical Research
• Biochemistry

Background:

• Acute pancreatitis can lead to severe complications like multiple organ failure and pancreatic necrosis.
• The prognosis of acute pancreatitis is significantly influenced by the extent of pancreatic necrosis.
• Effective debridement of necrotic pancreatic tissue is crucial for improving patient outcomes.

Purpose of the Study:

• To investigate the efficacy of collagenase in the debridement of experimentally induced pancreatic necrosis.
• To compare the effects of different collagenase administration methods on pancreatic necrosis.
• To evaluate hematological and histopathological changes following collagenase treatment in a rat model.

Main Methods:

• A rat model of necrotizing pancreatitis was established.
• Four experimental groups were formed: control pancreatitis, and three groups receiving collagenase via different administration routes (loge irrigation, loge instillation, intraperitoneal injection).
• Hematological parameters (leukocyte, hemogram, urea, AST, glucose, calcium, LDH, amylase) and histopathological features (edema, necrosis, inflammation, hemorrhage, fat necrosis) were assessed.

Main Results:

• No significant differences were observed in leukocyte, hemogram, or urea levels across groups.
• Statistically significant differences in AST levels were noted between Group I and II.
• Significant differences in glucose, calcium, LDH, AST, and amylase levels, as well as edema, acinar necrosis, inflammatory cell infiltration, hemorrhage, and fat necrosis, were observed between various collagenase treatment groups and the control group (P < 0.05).

Conclusions:

• The collagenase preparation demonstrated effectiveness in debriding pancreatic necrosis in this experimental model.
• Specific administration routes of collagenase (loge irrigation and instillation) showed significant improvements in histopathological markers compared to controls.
• Collagenase holds potential as a therapeutic agent for managing pancreatic necrosis in acute pancreatitis.
