Management of bowel obstruction in advanced and terminal cancer patients

Background: Bowel obstruction is a common and distressing outcomein patients with abdominal or pelvic cancer. Patients and methods: Patients may develop bowel obstructionat any time in their clinical history, with an incidence rangingfrom 5.5% to 42% in ovarian carcinoma and from 10% to 28.4%in colorectal cancer. The causes of the obstruction may be benignpostoperative adhesions, a focal malignant or benign deposit,relapse or diffuse carcinomatosis. The symptoms which are almostalways present are intestinal colic (reported in 72%–76%of patients), abdominal pain due to distension, hepatomegalyor tumor masses (in 92% of patients) and vomiting (68%–100%)of cases. Conclusion: While surgery must remain the primary treatmentfor malignant obstruction, it is now recognised that there isa group of patients with advanced disease or poor general conditionwho are unfit for surgery and require alternative managementto relieve distressing symptoms. A number of treatment optionsare now available for the patient with advanced cancer who developsintestinal obstruction. In this review of the literature, theindications for surgery will be examined, the use of nasogastrictube and percutaneous gastrostomy evaluated and the place ofdrugs for symptom control described. bowel obstruction, advanced and terminal cancer patients
