Colonic obstruction/perforation

Colonic obstruction refers to a blockage in the large intestine that prevents the normal passage of stool and gas. This obstruction can be caused by a variety of factors, including colorectal cancer, diverticulitis, volvulus (twisting of the colon), strictures (narrowing of the colon), or adhesions from previous surgeries. Symptoms of colonic obstruction include abdominal pain, bloating, constipation, and nausea, which may progress to vomiting and signs of dehydration if not addressed.

Diagnosis of colonic obstruction typically involves a combination of physical examination, imaging studies, and laboratory tests. Abdominal X-rays, CT scans, and sometimes MRI are used to visualize the obstruction, determine its location, and assess its cause. In some cases, a colonoscopy may be performed to directly view the colon and possibly relieve the obstruction if it is caused by a polyp or tumor.

Management of colonic obstruction depends on its severity and underlying cause. Treatment options may include conservative measures such as bowel rest, nasogastric tube insertion to decompress the stomach, and intravenous fluids. In cases where conservative treatment is ineffective or the obstruction is severe, surgical intervention may be required to remove the obstruction, repair any damaged areas, or address the underlying cause, such as removing a tumor or correcting a volvulus.

Colonic perforation is a serious complication where a hole forms in the wall of the colon, allowing intestinal contents to leak into the abdominal cavity. This can lead to peritonitis (inflammation of the abdominal lining) and sepsis, which are life-threatening conditions. Common causes of colonic perforation include diverticulitis, colorectal cancer, inflammatory bowel disease, and trauma.

Symptoms of colonic perforation may include sudden and severe abdominal pain, fever, rapid heartbeat, and signs of shock. Diagnosis typically involves physical examination, imaging studies such as abdominal X-rays or CT scans, and sometimes exploratory surgery to confirm the presence of perforation. Treatment usually requires urgent surgical intervention to repair the perforation and clean the abdominal cavity, along with antibiotics and supportive care to manage infection and inflammation.
