Fibrosing colonopathy is a disease that arises in people with cystic fibrosis treated with high doses of pancreatic enzyme supplements.[1][2] Symptoms are non-specific with abdominal pain, abdominal swelling, vomiting, and constipation.[1]

Fibrosing colonopathy
Other namesAbdominal pain, abdominal swelling, vomiting, constipation[1]
CausesHigh doses of pancreatic enzyme supplements[1]
Risk factorsYoung age, prior surgery of the intestines, certain medications including corticosteroids and H2 blockers[2]
Frequency>60 cases reported[2]

Risk factors include being young, prior surgery of the intestines, and the use of certain medications including corticosteroids and H2 blockers.[2] It may appear similar to distal intestinal obstruction syndrome or inflammatory colitis such as Crohn's disease.[1]

A maximum dose of 10,000 IU of lipase per kilogram per day is recommended for pancreatic enzyme supplementation to prevent this condition.[3] More than 60 cases have been described as of 1999.[2] The disease was suggested to be caused by methacrylic acid copolymer which is used as coating for delayed release of enzymes but there is no reliable evidence for that.[4]

Signs and symptoms

edit

Clinical symptoms of fibrosing colonopathy can be similar to those of intestinal obstruction and include constipation or diarrhea, abdominal pain, hematochezia,[5] vomiting, nausea, and poor weight gain.[6]

Causes

edit

The precise etiopathogenesis is still unknown. Young age (2–13 years), gastrointestinal history (DIOS, meconium ileus), abdominal surgery in the past, HDPE, and use of histamine H2-receptor blockers, corticosteroids, or recombinant human deoxyribonuclease (DNase) are risk factors.[7] Fibrosing colonopathy and cystic fibrosis have a strong correlation.[6]

Diagnosis

edit

The afflicted colon's histologic findings include thickening of the muscularis propria, submucosal fibrosis, a cobblestone-like appearance, and persistent mucosal inflammation.[8] With relative rectal sparing, imaging can demonstrate diffuse narrowing, shortening, and loss of haustration of the colonic lumen.[9]
