Background.Intestinalfailure impairs nutritional status and survival expectance. Though intestinal adaptation and enteral independence may be achieved, artificial nutrition is needed in about half of the patients. Aims. This study is aimed at assessing the causes of death, survivalrate, enteral independence in time, and factors affecting the clinical outcome in a group of patients with intestinal insufficiency. Patients. Sixty-eight patients with intestinal insufficiency, due to major intestinal resection in 60 cases (short bowel syndrome) (remnant intestine length 101–150 cm in 31 cases, 50–100 cm in 23 cases, <50 cm in 6 cases), and due to chronic idiopathic pseudo-obstruction in 8 cases, were enrolled and followed-up for (median) 36 months (25th and 75th percentile in 12 and 60 months, respectively). In 60 short bowel syndrome patients, the main conditions that led to intestinalfailure were ischemic bowel (28), major surgery complications or severe adhesions (17), radiation enteritis (10), Chron’s disease, intestinal tuberculosis, small bowel lymphoma and trauma (others). Methods. Seventeen variables age, underlying disorders, length of remnant bowel, type of surgery, hospital stay, type of nutrition (hospital and home) and its variations in time, causes of death, survivalrate and time were considered. Statistical analysis was carried out by Mann–Whitney U-test, Pearson χ2, Spearman correlation test, Kaplan–Meyer method and Cox’s proportion hazards regression model. Results. At the time of admission to the hospital, none of the patients had nutritional independence, 54 (79.4%) were on parenteral nutrition and 14 (20.6%) were on enteral nutrition. At the time of discharge, 23 (33.8%) patients showed enteral independence, 39 were on home parenteral nutrition, 3 on enteral nutrition + i.v. feeding, 1 on enteral nutrition, and 2 needed oral supplementation with hydroelectrolyte solutions only. After a median value of 36 months, 30 and 2 patients were on home parenteral nutrition and enteral nutrition + i.v. feeding, respectively, 2 on enteral nutrition, 2 on oral supplementation with hydroelectrolyte solutions, and 26 cases reached enteral independence. A significant relationship was detected between the length of remnant bowel and types of nutrition at both admission (r=0.38; P=0.001) and discharge (r=0.48; P=0.001), parenteral nutrition being more frequent in patients with very short bowel. Twenty-two patients (32.4%) died (4 from newly occurring malignancies), 40 (58.8%) survived, and 6 (8.8%) were lost to the follow-up. Eleven of 22 patients died from conditions related to intestinalfailure (8 cases) and/or home parenteral nutrition complications (3 cases). At 12, 24, 36, 48, 60 and 72 months, survivalrates were 95.4, 93.3, 88.1, 78.6, 78.6 and 65.5%, respectively, but it was significantly lower for patients with <50 cm of remnant bowel than those with longer residual intestine (P<0.05), and in patients who started home parenteral nutrition above the age of 45 years (P<0.02). Survivalrate was higher in patients with enteral independence than those with enteral dependence (P<0.05). Better survivalrates were registered in patients with chronic obstructive intestinal pseudo-obstruction and major surgery complications, whereas ischemic bowel and even more radiation enteritis were associated with a lower survival expectance. Conclusions. Actuarial survivalrate of patients with intestinalfailure quotes 88 and 78% at 3 and 5 years, respectively. It is influenced by the length of remnant intestine, age at the start of home parenteral nutrition, enteral independence and, to some extent at least, by the primary disorder. Enteral independence can be achieved in time by about 40% of the patients with intestinal insufficiency, but for home parenteral nutrition-dependent cases, intravenous feeding can be stopped in less than one out of five patients during a median 3-year period.

Abstract

Background.Intestinalfailure impairs nutritional status and survival expectance. Though intestinal adaptation and enteral independence may be achieved, artificial nutrition is needed in about half of the patients. Aims. This study is aimed at assessing the causes of death, survivalrate, enteral independence in time, and factors affecting the clinical outcome in a group of patients with intestinal insufficiency. Patients. Sixty-eight patients with intestinal insufficiency, due to major intestinal resection in 60 cases (short bowel syndrome) (remnant intestine length 101–150 cm in 31 cases, 50–100 cm in 23 cases, <50 cm in 6 cases), and due to chronic idiopathic pseudo-obstruction in 8 cases, were enrolled and followed-up for (median) 36 months (25th and 75th percentile in 12 and 60 months, respectively). In 60 short bowel syndrome patients, the main conditions that led to intestinalfailure were ischemic bowel (28), major surgery complications or severe adhesions (17), radiation enteritis (10), Chron’s disease, intestinal tuberculosis, small bowel lymphoma and trauma (others).
