Purpose:
Massive fecal impaction leading to surgical catastrophes has rarely been reported. We present 2 such patients to remind physicians that neglected accumulation of fecal matter in the rectum may lead to ischemia and perforation of the colon and rectum.
Methods:
Report of 2 patients and a MEDLINE search of the literature.
Results:
In the 1st case massive fecal impaction produced an abdominal compartment syndrome and rectal necrosis. In the 2nd patient fecal impaction resulted in colonic obstruction and ischemia. In both, an operation was life-saving.
Conclusion:
Neglected fecal impaction may lead to a megarectum causing an abdominal compartment syndrome and colorectal obstruction, perforation or necrosis. Measures to prevent fecal impaction are of paramount importance and prompt manual disimpaction before the above complications develop is mandatory. Appropriate operative treatment may be life-saving.
Insights
Massive fecal impaction can cause severe rectal and colon complications, including ischemia and perforation. Prompt intervention is crucial to prevent surgical emergencies and save lives.
Area of Science:
- Gastroenterology
- Colorectal Surgery
Background:
- Massive fecal impaction is a rare but serious condition.
- It can lead to life-threatening surgical complications.
Observation:
- Two cases of massive fecal impaction are presented.
- One patient developed abdominal compartment syndrome and rectal necrosis.
- The other patient experienced colonic obstruction and ischemia.
Findings:
- Neglected fecal impaction can result in a megarectum.
- This can lead to abdominal compartment syndrome and colorectal emergencies.
- Surgical intervention was life-saving in both reported cases.
Implications:
- Physicians must be aware of the potential for severe outcomes from fecal impaction.
- Preventive measures and prompt manual disimpaction are essential.
- Timely surgical treatment can be life-saving for patients with complications.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
