Intestinal and Multivisceral Transplantation
Updated: Jan 24, 2008
Introduction
Total parenteral nutrition (TPN) is the treatment of choice for patients with intestinal failure. Intestinal and multivisceral transplantation provides an alternative for patients who have life-threatening complications of TPN. Recent improvements in surgical technique, the monitoring and diagnosis of rejection, and cytomegalovirus (CMV) prophylaxis and the development of improved immunosuppression have paved the way for significant improvements in patient and graft survival rates. This article reviews the current status of intestinal and multivisceral transplantation, with emphasis on the authors' experience at the University of Miami.
History of the Procedure
Carrel performed the first experimental intestinal transplantation in 1902.1 Half a century later, in 1959, Lillehei demonstrated successful intestinal autotransplantation after cold preservation.2 Experimental multivisceral transplantation (termed polysplanchnic transplantation) was pioneered by Starzl in 1960.3 The earliest attempts at clinical intestinal transplantation were unsuccessful because of what appeared to be insurmountable barriers: graft rejection and infectious complications.4,5
The first successful intestinal transplantations occurred in the late 1980s. Grant reported successful intestinal transplantation in pigs with cyclosporine use in 1988.6 Starzl reported the first clinical successful multivisceral transplantation in 1987.7 In 1988, Goulet and Deltz independently reported the first successful isolated intestine transplantations.6 Grant reported the first combined liver and intestine transplantation under cyclosporine-based immunosuppression in 1990.8 Starzl, Todo, and Tzakis pioneered intestinal transplantation with tacrolimus in the early 1990s.7,9,10,11,12 As a result, the number of centers performing the procedures increased.13,14
The intestinal and multivisceral transplantation program at the University of Miami was started in 1994. Through September 2007, 278 intestinal transplantations have been performed, including 247 primary intestinal transplantations (65 isolated intestine, 32 combined liver-intestine, and 150 multivisceral transplantations) and 31 retransplantations (11 isolated intestine, 2 combined liver-intestine, and 18 multivisceral transplantations).
Problem
Short bowel syndrome is often the result of extensive intestinal resection for multiple pathophysiologies, such as volvulus, trauma, tumor, and thrombosis. An inadequate absorptive surface results in an inadequate energy intake and malabsorption of vitamin B-12 and other vitamins. Calcium and magnesium deficiencies can lead to neurologic complications such as encephalopathy, tetany, and convulsions. Intestinal failure with hyperalimentation causes liver failure. Patient with long-term hyperalimentation usually have complications, including line sepsis, thrombosed veins, and liver dysfunction.
Frequency
No database reports the exact incidence of short bowel syndrome. However, the incidence is estimated to be 1.8-2 patients per one million general population.
Etiology
The causes of intestinal failure include the following:- Mesenteric thrombosis
- Necrotizing enterocolitis
- Gastroschisis
- Volvulus
- Desmoid tumor
- Intestinal atresia
- Trauma
- Hirschsprung disease
- Crohn disease
- Pseudoobstruction
- Microvillus inclusion disease
- Massive resection of the intestine
At the University of Miami, all patients with intestinal failure that necessitated transplantation had TPN-related complications, and most had concurrent TPN-induced liver failure. The causes of intestinal failure and the number of patients affected are as follows:
- Mesenteric thrombosis - 29
- Necrotizing enterocolitis - 32
- Gastroschisis - 36
- Volvulus - 21
- Desmoid tumor - 14
- Intestinal atresia - 17
- Trauma - 16
- Hirschsprung disease - 16
- Crohn disease - 7
- Pseudoobstruction - 13
- Megacystic microcolon -10
- Microvillus inclusion - 8
- Others - 30
- Retransplant - 31
Pathophysiology
Extensive resection of the small bowel can cause short bowel syndrome. Extensive loss of the intestinal mucosa surface results in an inadequate absorptive surface. An inadequate caloric intake and malabsorption of vitamins, including vitamin B-12, can result in severe malnutrition and neurological symptoms. Inadequate electrolyte absorption (eg, calcium, magnesium) also results in severe neurological complications, including encephalopathy, tetany, and convulsions.
Presentation
All patients who received intestinal or multivisceral transplants at the University of Miami had life-threatening TPN-related complications, such as sepsis, central vein thrombosis, and cholestatic TPN-induced liver failure.
The recipients of isolated intestinal transplants had short bowel syndrome with severe central vein thrombosis and line sepsis. Liver functions were preserved.
The recipients of liver and small bowel transplants had short bowel syndrome and cholestatic TPN-induced liver failure. Total bilirubin levels were usually higher than 20 mg/dL.
The recipients of multivisceral transplants had short bowel syndrome and cholestatic TPN-induced liver failure. In addition, they usually had a history of surgery, abdominal trauma, motility disorders, tumors, and other etiologies.
Indications
The role of TPN in short bowel syndrome is established, and long-term TPN is the treatment of choice for these patients because of its well-documented long-term safety.15 A subset of patients with short bowel syndrome cannot tolerate TPN because of frequent episodes of catheter-associated sepsis, catheter-associated vascular thrombosis, or TPN-induced cholestasis. This is the subset of patients who need intestinal or multivisceral transplantation.
Line infection is the most common cause of fever and chills for patients with TPN. Gram-positive bacteria are the common pathogens. TPN-induced liver failure is the most common cause of jaundice in TPN therapy. If liver failure progresses, intestinal transplantation or intestinal and liver transplantation is indicated. See Etiology for the causes of intestinal failure and the experience at the University of Miami.
Liver function test findings must be carefully evaluated for derangements that suggest the need for biopsy evaluation. If significant fibrosis, macrosteatosis, or cirrhosis is present on liver biopsy findings, then liver transplantation is necessary. Evaluation of renal function is critical because of the need for long-term use of tacrolimus postoperatively.
Relevant Anatomy
For isolated intestinal transplantation in patients with normal anatomy, the superior mesenteric artery (SMA) of the donor is procured with the aortic cuff. The portal vein is cut above the confluence of the superior mesenteric and splenic vein. If a right replaced hepatic artery from the SMA is present, the SMA is cut distal to the takeoff of the replaced hepatic artery. The SMA of the donor is anastomosed to the recipient SMA or the abdominal aorta. The portal vein of the donor is anastomosed to the portal vein or the inferior vena cava of the recipient.
For liver and intestinal or multivisceral transplantation, the celiac trunk and SMA are procured with the abdominal aorta and thoracic aorta. The inferior vena cava is procured from the iliac vein bifurcation to above the diaphragm. The anastomosis is performed between the donor abdominal aorta and the recipient abdominal aorta in an end-to-side fashion.
Contraindications
Transplantation is contraindicated if the recipient has active infection such as pneumonia, sepsis, or fungal infection. Because of the immunosuppressive medication used in the postoperative period, the infection must be controlled by antibiotics or antifungal therapy before transplantation.
