he was on parenteral nutrition (PN) through chemoport. Over the next 2 years, he had seven episodes of line sepsis, two of which were potentially life threatening. Over 4 years, he lost 36 kg, had poor quality of life, loss of self-esteem, and developed suicidal tendencies. He was evaluated (Table 1) and found suitable for an isolated intestinal transplant. The donor was a 21-year-old man who had head injury in a road accident in the same city. He was hemodynamically stable with normal hematology, serology, and biochemistry except raised sodium of 162 mmol/L. The small intestinal graft was accepted after confirmation of negative T and B cell lymphocytic crossmatch and correction of sodium and retrieved in the standard fashion. In the recipient, adhesiolysis was performed; the distal ileal remnant and the proximal half of the colon were resected. Under thymoglobulin (ATG) induction, intestinal graft was implanted with inflow from infra-renal aorta and outflow into portal vein using vascular conduits, resulting in uniform reperfusion. Bowel continuity was established by jejunojejunal and ileocolic two-layer anastomoses, leaving a 20-cm “chimney ileostomy”. He was given enteral feeds at 2 weeks and oral diet at 3 weeks after transplant when PN was stopped. He had two episodes of rejection in the first 6 weeks, which responded to ATG and steroids, respectively. After discharge, he developed chylous ascites, and required three re-admissions for intercurrent problems, all of which settled on conservative management. He is well 10 months after the transplant.

Abstract Intestinal transplant is a therapeutic challenge not just surgically but also logistically because of the multidisciplinary expertise and resources required. A large proportion of patients who undergo massive bowel resection and develop intestinal failure have poor outcome, because of inability to sustain long-term parenteral nutrition and limited availability of intestinal and multi-visceral transplantation facilities.

with expertise in intestinal transplantation, standardization of perioperative management protocols, and sensitization of surgeons performing massive resection about intestinal transplant, and of organ retrieval centers about suitable intestine donors are essential for future success in this field.

Introduction Long-term parenteral nutrition (PN) and intestinal transplant (ITx) are the cornerstones of management of intestinal failure. The latter develops when inadequate physical or functional length of small bowel fails to adapt enough to maintain electrolyte, nutrient, and fluid balance without PN. Intestinal failure in adults usually results from short gut syndrome because of repeated/massive resections in Crohn’s disease, superior mesenteric artery, or venous thrombosis or trauma, whereas in children, intestinal atresia, gastroschisis, Crohn’s disease, or microvillus involution disease [1] are the main causes. Short bowel syndrome may manifest as massive diarrhea, high stoma output, electrolyte abnormalities, fat and vitamin B 12 malabsorption, gastric hypersecretion, hyperbilirubinemia, or hepatic steatosis [2]. Altough PN has been the first line of therapy for such patients, it is expensive, cumbersome, and commonly associated with potentially life-threatening complications, such as catheter-related sepsis and/or venous thrombosis, stenosis or occlusion, metabolic derangements, and liver dysfunction, especially in the long-term. The intestine is capable of significant adaptation as a result of villous hypertrophy leading to increased absorptive surface. This may lead to a complete or partial independence from PN in patients with more than 50 cm of small bowel, especially those with a preserved ileocecal valve [3, 4]. In those who fail to adapt and cannot maintain on PN, ITx is the next logical step. Although the results of ITx have recently improved, the requisite expertise and experience in the complex perioperative management of these chronically sick and malnourished patients remains restricted to only a few centers worldwide. We hereby report India’s first successful deceased donor isolated intestinal transplant.

Case report A 27-year-old previously healthy male, a software engineer by profession, presented in December 2009 with continuous, nonradiating, severe, central abdominal pain, tachycardia, generalized abdominal tenderness, absent bowel sounds, progressive abdominal distension, and leukocytosis. A CT scan of the abdomen revealed a distended small and large intestine and pneumatosis intestinalis. Laparotomy revealed extensive small intestine gangrene due to superior mesenteric vein

thrombosis for which he underwent resection of the entire small intestine except the first 12 cm of jejunum and last 16 cm of terminal ileum, with primary jejuno-ileal anastomosis. He recovered well and was discharged on peripheral PN and limited oral liquids. He did not thrive well with peripheral PN, lost 36 kg (74 kg to 38 kg), and stopped going to work. A chemoport was inserted and central PN was given, with which he gained about 5 kg, but soon he had three episodes of central line-related sepsis necessitating chemoport removal. He came to us a year after his initial bowel resection, with history of line sepsis, poor tolerance to oral diet, and significant weight loss. He was counseled, evaluated and listed for an isolated small bowel transplant. A fresh chemoport was dedicated for PN and the peripherally inserted central catheter (PICC) line was used for blood sampling and medications. He developed familial intentional ataxia, which resolved with trace element supplementation. Over the next 3 years, he had several periods of absence (total, 20 months) from work due to PN, which improved with institution of weekend PN. He was hospitalized 11 times, had a poor social life, and developed feelings of low self-esteem and suicidal tendencies for which he needed professional help. He also had four further episodes of line sepsis, with the last one being 4 months before the transplant, requiring chemoport removal. His home PN regimen consisted of 4–5 L/week of Kabiven® (each liter containing 900 kcal, 100 kcal protein, 800 kcal nonprotein calories, 100 g carbohydrates, and 40 g 20 % fat; Fresenius Kabi AG, Hamburg, Germany) which he took from Friday to Sunday nights. Additionally, he needed 500 to 1,500 mL intravenous (IV) fluid every day to achieve normal hydration. He also received calcium, magnesium, vitamins D3, E, B complex, and B12, folic acid daily, and Inj Celecel® (trace elements include: chromium chloride, copper, manganese, zinc, and selenium; Claris Lifesciences Limited, Ahmadabad, India) twice a week. He was monitored with complete blood count, liver and kidney function tests, and cultures at clinic visits every 15 days.

The operation The operative and postoperative protocols were adapted from those successfully used by the last author (AK) for over 500 cases of bowel transplant at UPMC [5]. The donor was a blood group-matched 21-year-old, 70-kg, lean man who had head injury in a road traffic accident at another hospital in the city. He had been in the ICU for 80 hours, and there was no history of cardiac respiratory arrest. His hematological, liver and kidney function tests were normal and hepatitis and HIV serology were negative. His peak serum sodium was 162 mmol/L 8 hours prior to organ retrieval, which was brought down to 152 at the time of retrieval. The T and B cell flow-cytometry lymphocytic crossmatch were negative.

Prior to organ recovery, the donor was given IV meropenem, fluconazole, teicoplanin, metronidazole, and bowel decontamination with colistimethate, amphotericin, and tobramycin via a nasogastric tube. The graft was perfused with 8 L of UW (University of Wisconsin, Belzer UW®, Bridge to Life Ltd, Columbia, SC, USA) solution through the aorta. The entire

small bowel from proximal jejunum to distal ileum was retrieved based on the superior mesenteric vein (SMV), up to just beyond the SMV-splenic vein junction and superior mesenteric artery (SMA). The ends of the bowel graft were stapled (Proximate GIA TLC 75 Ethicon Endosurgery LLC, Somerville, NJ, USA). The graft was “triple bagged”

and transported in cold UW solution at 4 deg C (Fig. 1a). Meanwhile, upon inspection and approval of the graft quality by the donor surgeon, recipient surgery was begun. Dense adhesions in the abdominal cavity were lysed. The remnant small bowel and proximal half of colon were mobilized off the retroperitoneum, inferior vena cava (IVC) and aorta, and resected to make space for the intestinal graft. The infra-renal aorta was exposed 5 cm below the origin of the right renal artery and a 5-cm long and 8-mm wide donor iliac artery conduit was anastomosed end-to-side to it (Fig. 1b). Since the SMV was thrombosed, portal vein (PV) was exposed in the hepato-duodenal ligament and a 6-cm long and 1.5 cm wide venous conduit (cryopreserved external iliac vein) was anastomosed end-to-side to it. Immunosuppression induction was done with anti-thymocyte globulin (ATG) 5 mg/kg and methylprednisolone (MP) 15 mg/kg intravenously. The intestinal graft was orientated appropriately, and implanted by anastomosing the graft SMA to the aortic conduit and the graft portal vein to the recipient PV conduit (Fig. 1c). The cold and warm ischemia times were 256 and 28 minutes, respectively. On reperfusion, the graft ‘pinked up’ immediately (Fig. 1d). Both ends of graft bowel were oversewn using interrupted silk sutures. Proximal bowel continuity was established by a graft-recipient side-to-side, double-layered jejunojejunostomy (inner continuous PDS and outer interrupted silk sutures). Distally, a side-to-side, double-layered ileo-

transverse colic anastomosis (inner continuous PDS and outer interrupted silk sutures) was done leaving 20 cm of the graft distal ileum, which was fashioned into a ‘chimney ileostomy’ (Fig. 1e). A nasojejunal (NJ) tube (Freka® Trelumina, Fresenius Kabi AG, Hamburg, Germany) was kept beyond the proximal bowel anastomosis.

Postoperative course Postoperatively, the patient was managed in an isolation room in the intensive care unit (ICU) for 6 days following which he was shifted to the ward. Both the ICU and ward rooms were positive pressure isolation rooms equipped with high efficiency particulate air filter and UV radiation. His monitoring protocol is outlined in Table 2. He was extubated 14 hours after the surgery and administered IV antibacterials, antifungals, antivirals and NJ gut decontamination. He was ambulated on postoperative day (POD) 4. PN (Kabiven) was given at 85 mL/hours in addition to calcium, magnesium, phosphate and trace element supplementation. NJ feeding was started on POD 15 and slowly increased over 10 days. PN was commensurately reduced from POD 15 and was stopped by POD 25. Oral feeding was started with liquids, followed by semi-solids and then normal diet from POD 22 onwards. By POD 30, he was completely on oral diet, with occasional need to supplement fluid intake of 500–1,000 mL every day.
