RESUMO

The United Network for Organ Sharing database was examined for trends in the intestinal transplant (ITx) waitlist from 1993 to 2012, dividing into listings for isolated ITx versus liver-intestine transplant (L-ITx). Registrants added to the waitlist increased from 59/year in 1993 to 317/year in 2006, then declined to 124/year in 2012; Spline modeling showed a significant change in the trend in 2006, p < 0.001. The largest group of registrants, <1 year of age, determined the trend for the entire population; other pediatric age groups remained stable, adult registrants increased until 2012. The largest proportion of new registrants were for L-ITx, compared to isolated ITx; the change in the trend in 2006 for L-ITx was highly significant, p < 0.001, but not isolated ITx, p = 0.270. New registrants for L-ITx, <1 year of age, had the greatest increase and decrease. New registrants for isolated ITx remained constant in all pediatric age groups. Waitlist mortality increased to a peak around 2002, highest for L-ITx, in patients <1 year of age and adults. Deaths among all pediatric age groups awaiting L-ITx have decreased; adult L-ITx deaths have dropped less dramatically. Improved care of infants with intestinal failure has led to reduced referrals for L-ITx.

RESUMO

Organ transplantation carries a risk of disease transmission from donor to recipient, primarily infection or malignancy. Although donors are thoroughly screened, donor-related malignancies are reported to occur in 0.01% of solid organ transplants. Plasma cell neoplasm, to the best of our knowledge, has not been reported as a donor-transmitted malignancy in liver transplantation. We describe a liver transplant from a donor with unrecognized plasmacytoma requiring retransplantation. Three years after the first transplant a single peritoneal mass was detected on surveillance imaging and radically excised; HLA phenotyping confirmed the mass to be an isolated extra-medullary plasmacytoma of chimeric donor and recipient origin.

RESUMO

BACKGROUND: We evaluated the outcome of combined liver-lung transplantation (L-LTx) in cystic fibrosis (CF) patients with liver transplantation (LTx) for CF liver disease. METHODS: The United Network for Organ Sharing (UNOS) data were analyzed from October 1987 to August 2009. RESULTS: Of 294 patients (210 children), 265 (90.1%) received an LTx and 29, an L-LTx. Patient survival was: adult LTx, 80%, 74%, and 67% at 1, 3, and 5 years, and L-LTx, 72%, 61.4%, and 61.4% (P = .7); pediatric LTx, 85%, 82%, and 74% at 1, 3, and 5 years, and L-LTx, 83%, 83%, and 83% (P = .4). Pediatric patients had a slight survival advantage over adults for LTx (P = .08). Graft survival, not affected by immunosuppression regimens, was similar to patient survival. CONCLUSIONS: The outcome of L-LTx appears similar to LTx in CF providing support for the prospect of a combined transplant.

RESUMO

BACKGROUND: The pathophysiology of Crohn's disease (CD) is related to immune dysregulation making it unique among indications for intestinal transplants (ITx). We examined whether outcomes of ITx for CD are any worse than the overall ITx population. METHODS: United Network for Organ Sharing Standard Transplant Analysis and Research files were analyzed. Adult ITx recipients from 1987 to 2009 were included. RESULTS: Of 86 primary ITx for CD, 61 (70%) had isolated ITx and 25 (30%) had liver-ITx (L-ITx). The 1-, 3-, and 5-year patient survival for isolated ITx was 85%, 67%, and 54%; for L-ITx, 63%, 47%, and 41% (P = .04). The graft survival at 1, 3, and 5 years was 85%, 55%, and 45% for isolated ITx recipients and 63%, 47%, and 41% for L-ITx recipients (Wilcoxon's test, P = .04). Patient and graft survival was better in era 2 (January 2001 through August 2009) than in era 1 (October 1987 through December 2000). In the regression analysis of long-term outcome of adults undergoing ITx, recipient age > 40 years and hospitalization prior to transplantation were negative predictors of outcome. CONCLUSION: Patient and graft survival for CD patients is not inferior to other indications for ITx.

RESUMO

Outcomes of intestinal transplants (ITx; n = 977) for pediatric patients are examined using the United Network for Organ Sharing data from 1987 to 2009. Recipients were divided into four age groups: (1) <2 years of age (n = 569), (2) 2-6 years (n = 219), (3) 6-12 years (n = 121) and (4) 12-18 years (n = 68). Of 977 ITx, 287 (29.4%) were isolated ITx and 690 (70.6%) were liver and ITx (L-ITx). Patient survival for isolated ITx at 1, 3 and 5 years, 85.3%, 71.3% and 65.0%, respectively, was significantly better than L-ITx, 68.4%, 57.0% and 51.4%, respectively, (p = 0.0001); this was true for all age groups, except for patients <2 years of age. The difference in graft survival between isolated ITx and L-ITx was significant at 1 and 3 years (Wilcoxon test, p = 0.0012). After attrition analysis of graft survival of patients who survived past first year, 3 and 5 years, graft survival for L-ITx patient was significantly better than those for isolated ITx. Isolated ITx should be considered early before the onset of liver disease in children >2 with intestinal failure but is not advantageous in patients <2 years.

RESUMO

INTRODUCTION: Renal artery aneurysms (RAA) are extremely rare clinical entities with associated morbidities including hypertension and rupture. Although most RAA can be treated with in vivo repair or endovascular techniques, these may not be possible in patients with complex RAA beyond the renal artery bifurcation. We report a case of RAA in a patient with a solitary kidney that we treated successfully by extracorporeal repair and autotransplantation and the 2-years follow-up. CASE REPORT: A 64-year-old woman with a history of right nephrectomy for renal cell carcinoma presented with RAA found on routine computed tomography (CT). Preoperative workup demonstrated a 2.2 × 2.1 × 3-cm aneurysm in the distal left renal artery that was not amendable to in vivo or endovascular repair. The patient underwent a laparoscopic-assisted left nephrectomy, ex vivo renal artery aneurysm repair, and autotransplantation. She did well postoperatively and in clinic follow-up was found to have a creatinine of 1.2 mg/dL at the end of 2 years and stable blood pressure control. DISCUSSION: This patient with RAA in her solitary kidney was successfully treated with laparoscopic-assisted nephrectomy, ex vivo repair, and autotransplantation. Her creatinine was stable postoperatively despite absence of a second kidney.

RESUMO

We report the case of a successful multivisceral transplant in which both donor and recipient presented aberrant anatomy of the celiac-mesenteric axis requiring five separate arterial anastomoses to reconstruct the blood inflow to the graft.

RESUMO

BACKGROUND: Impalpable testis is a significant diagnostic and therapeutic challenge in adults, for both radiologist and surgeons, with few reports in literature addressing this problem in adults. Laparoscopy is a reliable and definitive procedure obviating the necessity of advance investigation and subsequent inguinal exploration in adults. AIMS: To study the utility of laparoscopy as combined diagnostic and therapeutic modality for undescended testis in adults. SETTINGS AND DESIGN: Prospective study from a single surgical unit of a large tertiary referral centre during August 2000 to January 2002. METHODS AND MATERIAL: Nine patients of unilateral undescended testis with average age 22.7 years (range 13-31 years) underwent diagnostic laparoscopy and orchidectomy subsequent to detailed clinical, ultrasound and examination under anaesthesia (EUA) procedure. All patients were operated with one 10 mm umbilical camera port, one suprapubic port and 1 lateral port. RESULTS: None of the patients had palpable testis or an inguinal cough impulse on clinical examination and during EUA. In only 3(33.3%) patients, the ultrasound could locate the testis situated at the deep ring. On laparoscopy all testes were identified, 4 were present at the deep ring, 3 were intra-abdominal and 2 had blind ending vas entering the deep ring. Mesh plug was inserted in the internal ring in these 2 patients, after dissecting the peritoneum. None of the patients had intra or post-operative complications and all were discharged on the next day. CONCLUSION: Laparoscopy is one of the most satisfactory methods for the diagnosis and management of non-palpable testis in adult cryptorchid patients.

RESUMO

OBJECTIVE: To study the incidence of antral varices (AV) and their fate in patients with portal hypertension so as to formulate a management policy. DESIGN: Prospective cohort study. SETTING: Single surgical unit specializing in portal hypertension management in a tertiary level centre. PARTICIPANTS: Three hundred and seventy-one patients [cirrhosis 170, non-cirrhotic portal fibrosis (NCPF) 53, extrahepatic portal venous obstruction (EHPVO) 148] with history of bleeding from oesophageal varices were inducted in the chronic sclerotherapy programme. INTERVENTIONS: Protocol-based endoscopic sclerotherapy and management of bleeding for oesophageal varices. OUTCOME MEASURES: Development or disappearance of AV, bleeding from AV. RESULTS: No patient had AV on index endoscopy. Thirteen (3.5%) patients developed AV, in cirrhosis 2.9%, EHPVO 4.1%, NCPF 3.8% (P = 0.86). AV developed after a mean of 15 months. Oesophageal varices took a longer number of sessions to obliterate in patients with AV (11.1 vs 5.98 sessions, P<0.0001). Only one patient bled, having coexistent oesophageal varices and gastropathy. AV disappeared spontaneously in seven patients, recurring in only one. Of seven persisting AV, none have bled over a mean follow-up of 30 months (SD 23.2). CONCLUSIONS: AV are seen in a small proportion of patients, and are distributed equally amongst the aetiologies of portal hypertension. They rarely bleed and may be ignored during sclerotherapy of oesophageal varices.
