Alvimopan (trade name Entereg) is a drug which behaves as a peripherally acting μ-opioid receptor antagonist.With the limited ability to cross the blood–brain barrier and reach the μ-opioid receptors of the central nervous system, the clinically undesirable effects of centrally acting opioid antagonists (like reversal of opioid-mediated analgesia) are avoided without affecting the intended ...
The distinction helps to narrow the possible causes and treatment. Common causes of small bowel obstruction include post-operative adhesions, hernias, intussusception, and intraabdominal tumors. Common causes of colonic obstruction include primary colon cancer, volvulus and post-operative adhesions. When the ileocecal valve is competent ...
Ileus, which refers to functional obstruction or aperistalsis of the intestine, is a physiologic response to abdominal surgery, including the Whipple procedure. [34] While post-operative ileus is typically self-limited, prolonged post-operative ileus occurs when patients develop nausea, abdominal distention, pain or intolerance of food by mouth ...
In December 2005, Wyeth and Progenics entered into an exclusive, worldwide agreement for the joint development and commercialization of methylnaltrexone for the treatment of opioid-induced side effects, including constipation and post-operative ileus (POI), a prolonged dysfunction of the gastrointestinal tract following surgery. Under the terms ...
In many cases, opioids used in general anaesthesia can cause postoperative ileus, even after non-abdominal surgery. Administration of a μ-opioid antagonist such as alvimopan immediately after surgery can help accelerate the timing of hospital discharge, but does not reduce the development of paralytic ileus. [65]
Paralytic ileus: short-term paralysis of the bowel; Perioperative mortality, any death occurring within 30 days after surgery; Shock; Sterile technique, aseptic post-operative care, antibiotics, use of the WHO Surgical Safety Checklist, and vigilant post-operative monitoring greatly reduce the risk of these complications. Planned surgery ...
From the gallbladder, bile enters the intestine in individual portions. In the absence of a gallbladder, bile enters the intestine constantly, but in small quantities. Thus, it may be insufficient for the digestion of fatty foods. Postcholecystectomy syndrome treatment depends on the identified violations that led to it.
Bloody diarrhea and leukocytosis in the postoperative period are essentially diagnostic of ischemic colitis. The complication can be prevented through careful selection of subjects that may require replanting inferior mesenteric artery (IMA) and completing the pre surgical procedure information with an instrumental evaluation during surgical ...
