RESUMEN

Introduction: Basidiobolomycosis is a rare fungal infection caused by an environmental saprophyte, Basidiobolus ranarum. It usually presents as a chronic subcutaneous infection; however, few cases of gastrointestinal involvement have been reported. The exact transmission route of gastrointestinal cases is not clear, and diagnosis always requires a high index of suspicion because it tends to mimic other inflammatory and neoplastic conditions. Case Report. A 31-year-old immunocompetent woman presented with abdominal pain and an advanced colon mass. She was completely well until about 1.5 years ago, when she underwent bariatric surgery. One year after surgery, chronic abdominal pain developed. A colonoscopy showed an ulcerative lesion in the descending colon, and the biopsy was in favor of ulcerative colitis. Despite immunosuppressive treatment, there was no improvement, and with worsening symptoms, more investigations revealed advanced colon mass with entrapment of the stomach and pancreas. Colonic mucosa biopsy and trucut biopsy of the mass showed just necrosis and acute inflammation; thus, she underwent exploratory laparotomy with colectomy, partial gastrectomy, distal pancreatectomy, and left nephrectomy. On pathologic examination, there was granulomatous inflammation plus the Splendore-Hoeppli phenomenon around fungal hyphae, which was diagnostic for gastrointestinal basidiobolomycosis. Previous pathology slides were reviewed and revealed a tiny focus of basidiobolomycosis. After 6 months of treatment with itraconazole, she is relatively well without any clinical or radiologic abnormalities. Conclusion: Our case highlights the significance of suspicion for basidiobolomycosis in ulcerative and necrotic lesions with increased eosinophils, especially in the presence of abdominal mass and systemic eosinophilia.

RESUMEN

BACKGROUND: Situs inversus totalis is a rare congenital anomaly characterized by a mirror-image orientation of abdominal, and in some cases, thoracic organs. Here, we report our situs inversus totalis transplantation experience and further review liver transplantations in adult recipients and donors with situs inversus totalis. CASE PRESENTATION: We describe three cases with situs inversus totalis. The first case was liver transplantation in a recipient (a 61-year-old Iranian man) with situs inversus totalis, the second was a liver transplantation from a donor (a 52-year-old Iranian woman) with situs inversus totalis, and finally, for the first time, a simultaneous pancreas and kidney transplantation in a recipient (a 26-year-old Iranian man) with situs inversus totalis. In patient one, hepatectomy could be performed according to the standard method and on the basis of preoperative studies. Hepatic vein and arterial anastomosis were performed as in every other patient without situs inversus totalis. To prevent biliary complications, a Roux-en-Y hepaticojejunostomy was performed. In patient two, implantation time, suprahepatic vein, portal vein, arterial, and biliary reconstruction could be done as in any other case without situs inversus totalis. Plication of the right-sided diaphragm and fixation of the falciform ligament was done for our patient. In patient three, systemic drainage was preferred to portal flow for establishing the outflow drainage of the pancreas compared with otherwise normal patients. CONCLUSION: Although situs inversus totalis is a rare condition, our reported techniques are suitable, considering advantages such as easier accessibility, more acceptable placement of the implanted organs regarding vascular variations, and the appropriate location of the allograft in the proximity of other organs.

RESUMEN

Intestinal failure (IF) remains as a life-threatening medical condition worldwide, but the disparity on the type and quality of medical care available, together with the different limitations to access among individual countries or regions, turned IF assessment and therapy into a difficult matter, which becomes a major hazard for the developing world. This article aims to provide an update regarding definitions used, the current general worldwide data, the developments, achievements, and the different access alternatives in Latin-America, Middle East, and Asia to exemplify what can be done to help patients with IF.

RESUMEN

Aim: The purpose of this retrospective single-center study was to determine the frequency of sarcopenia and its association with mortality and other morbidities in children with chronic liver disease who had undergone liver transplantation. Background: Sarcopenia, a muscle-wasting syndrome, is common in patients with advanced liver disease and is associated with increased morbidity and mortality. While sarcopenia in adults has been extensively studied, there is little information in this regard about children and adolescents with chronic liver diseases. Methods: The study included 108 children and adolescents who had undergone liver transplantation. Sarcopenia was measured using skeletal muscle index at the third lumbar vertebral level and assessed using abdominal computed tomography imaging. Results: The frequency of sarcopenia in the studied population was found to be 45.7%. Patients with sarcopenia were more likely to be male (P<0.0001), older (P<0.0001), and had lower height-for-age z-scores (P=0.012). Genetic/metabolic diseases were the most common underlying cause of sarcopenia in children. Except for a higher rate of transplant rejection in the sarcopenia group (P=0.035), there was no significant difference in mortality rates (P=0.688) or post-LT complications between the two groups. One year after LT, computed tomography-derived body composition parameters revealed no significant differences between children who survived and those who did not. Conclusion: Our findings indicated a high frequency of sarcopenia in children with chronic liver disease, implying that more research is needed to better understand its impact on clinical outcomes in this population.

RESUMEN

OBJECTIVES: The recurrence of underlying diseases remains a major cause of graft failure after liver transplant. This study aimed to identify factors associated with the recurrence of underlying diseases and investigate the incidence of these factors and recurrence at the main liver transplant center in Iran. MATERIALS AND METHODS: We included adult liver transplant recipients followed at Shiraz Transplant Center between 2011 and 2018 with a confirmed diagnosis of recurrence of underlying disease in our study. We reviewed medical records and extracted data on demographic characteristics, clinical and paraclinical features, medication use, and current status. We used a systematic random sampling method to select a control group of 95 transplant recipients who did not have recurrence. Of 3022 total transplant recipients, 76 recipients experienced a recurrence of their underlying disease. RESULTS: Model for End-Stage Liver Disease score, underlying disease, recipient blood group, donor sex, donor blood group, and rejection frequency were significantly different between study groups with and without recurrence of underlying diseases. Liver transplant recipients with recurrence had lower mean Model for End-Stage Liver Disease score. Recipients with recurrence also had higher rate of drug consumption (eg, prednisolone, tacrolimus, mycophenolate mofetil, sirolimus). Regression analysis showed that donor sex and rejection frequency had an effect on disease recurrence. Death occurred more frequently in liver transplant recipients with recurrence than in the control group (39.5% vs 26.3%), butthe difference was not significant. CONCLUSIONS: Donor sex and acute rejection frequency are independent factors predictive of the recurrence of underlying disease. Modifying risk factors can help minimize the recurrence of underlying diseases after liver transplant.

RESUMEN

OBJECTIVES: Identification of chronic rejection risk factors in liver transplant recipients is critical for early detection and prevention of further graft loss. We investigated characteristics of liver transplant recipients who had experienced chronic rejection and the associated risk factors versus patients without chronic rejection. MATERIALS AND METHODS: Data from 3022 adult liver transplant recipients between 2011 and 2018 were analyzed; of these, 80 patients had experienced chronic rejection. The control group included 98 randomly selected liver transplant recipients who did not have chronic rejection. RESULTS: The age of the recipients and the donors was significantly lower in the group with chronic rejection versus the group without chronic rejection.The results indicated that chronic rejection was significantly associated with the sex of the recipients (hazard ratio 3.2, 95% CI 1.77-6.08; P < .001) and with the sex concordance between the recipients and donors (hazard ratio 2.93, 95% CI 1.67-5.13; P < .001, respectively). Also, in the group without chronic rejection, there were no male donors; however, the group with chronic rejection had mostly male donors (P <.001). Cold ischemia time was longer in patients with chronic rejection versus that shown in the control group (P = .031), and there was a significant difference between the 2 groups in acute rejection frequency (P < .001). CONCLUSIONS: Recipient sex and sex concordance were independent risk factors for chronic rejection. Most transplantrecipients with chronic rejection responded to medicaltreatment, and the rate of graftloss was low among our recipients.

RESUMEN

BACKGROUND: Hepatic artery thrombosis (HAT) is one of the critical conditions after an orthotopic liver transplant (OLT) and leads to severe problems if not corrected promptly. However, multiple treatments have been proposed for HAT, in which surgical revascularization with either auto-hepatic conduit interposition (AHCI) or revision of the anastomosis is more familiar indeed indicated for some patients and in specific situations. In this study, we want to evaluate the success and outcomes of treating early HAT (E-HAT), which defines HAT within 30 days after OLT with either of the surgical revascularization techniques. METHOD: In this retrospective study, we collected information from the medical records of patients who underwent either of the surgical revascularization procedures for E-HAT after OLT. Patients who needed early retransplantation (RT) or died without surgical intervention for E-HAT were excluded. Demographic data, OLT surgery information, and data regarding E-HAT were gathered. The study outcomes were secondary management for E-HAT in case of improper inflow, biliary complications (BC), RT, and death. RESULTS: A total of 37 adult patients with E-HAT after OLT included in this study. These E-HATs were diagnosed within a mean of 4.6 ± 3.6 days after OLT. Two patients had their HA revised for the initial management of E-HAT; however, it changed to AHCI intraoperatively and finally needed RT. Two and nine patients from the AHCI and revision groups had re-thrombosis (12.5% vs. 47.3%, respectively, p = 0.03). RT was used to manage rethrombosis in all patients of AHCI and two patients of the revision group (22.2%). In comparison to the AHCI, revision group had statistically insignificant higher rates of BC (47.4% vs. 31.2%); however, RT for nonvascular etiologies (12.5% vs. 5.3%) and death (12.5% vs. 10.5%) were nonsignificantly higher in AHCI group. All patients with more than one HA exploration who were in the revision group had BC; however, 28.5% of patients with just one HA exploration experienced BC (p < 0.001). CONCLUSION: Arterial conduit interposition seems a better approach for the initial management of E-HAT in comparison to revision of the HA anastomosis due to the lower risk of re-thrombosis and the number of HA explorations; indeed, BC, RT, and death remain because they are somewhat related to the ischemic event of E-HAT than to a surgical treatment itself.

RESUMEN

It is well known that vitamin D plays a pivotal role in immune system modulation; however, its role in liver transplantation (LT) has not yet been well elucidated. This study aimed to assess the association between vitamin D status and LT outcomes. This retrospective cohort study was conducted on 335 registered cirrhotic patients with end-stage liver disease (ESLD) who underwent LT during 2019-2021 and had measurement of serum vitamin D before LT. The association of vitamin D levels before LT with the odds of acute cellular rejection (ACR) and risk mortality was assessed by applying logistic and cox regression, respectively. The mean MELD-Na and serum level of vitamin D were 20.39 ± 9.36 and 21.52 ± 15.28 ng/ml, respectively. In the final adjusted model, there was a significant association between vitamin D deficiency in the pre-transplant period and odds of ACR (odds ratio [OR] 2.69; 95% confidence interval [CI] 1.50-4.68). Although in the crude model, vitamin D deficiency in the pre-transplant period was significantly associated with an increased risk of mortality after two years of follow-up (Hazard ratio (HR) = 2.64, 95% CI 1.42-4.33), after adjustment for potential confounders, the association of vitamin D status and mortality became non-significant (HR = 1.46, 95% CI 0.71-3.00). The present study provides evidence that pre-transplant serum vitamin D levels may be a predictor for ACR in patients with cirrhosis undergoing LT.

RESUMEN

INTRODUCTION: Simultaneous pancreas kidney (SPK) transplantation is an invaluable procedure to enhance the quality of life of insulin-dependent patients with advanced renal disease. The creation of vascular anastomoses of the donor's pancreas vessels to the recipient's, is of utmost importance to predict the graft outcome and surgical complications. In the study we introduce a novel technique for arterial reconstruction during SPK transplantation. METHODS: Conventionally, during the SPK transplantation, a so-called Y-graft is anastomosed between donor's superior mesenteric and splenic artery to the recipient's right iliac artery. In the study we adopted a new technique by preparing an extra extension using the donor's carotid artery, to be anastomosed to the Y-graft and the iliac artery. In this non-blinded randomized clinical trial we compared the surgical complications and early outcomes between the 2 groups of patients with the traditional and new arterial reconstruction techniques during 3 months after transplantation. RESULTS: Thirty adult patients were included in the study. The incidence of pancreatitis, vascular thrombosis and surgical site infection was lower in the new Y-graft and extension technique, which was not statistically significant. However, the calculated Cohen's d index showed the medium effect of new Y-graft and extension technique on complication after SPK transplantations. CONCLUSION: The post-operative complications tend to be lower in the novel arterial reconstruction technique, however a study on a larger patient group is encouraged to confirm our primary results. TRIAL REGISTRATION: The study was registered at the Iranian Registry of Clinical Trials on 12/05/2022; IRCT 20210625051701N2; ( http://www.irct.ir/ ).

RESUMEN

BackgroundImmunocompromised patients have lower seroconversion rate in response to COVID-19 vaccination. The aim of this study is to evaluate the humoral immune response with short-term clinical outcomes in solid organ transplant recipients vaccinated with SARS-CoV-2 vaccine (BBIBP-CorV; Sinopharm).MethodsThis prospective cohort was conducted from March to December 2021 in Abu Ali Sina hospital, Iran. All transplant recipients, older than 18 years were recruited. The patients received two doses of Sinopharm vaccine 4 weeks apart. Immunogenicity was evaluated through assessment of antibodies against the receptor-binding domain (RBD) of SARS-CoV-2 after the first and second dose of vaccine. The patients were followed up for 6 months after vaccination.ResultsOut of 921 transplant patients, 115 (12.5%) and 239 (26%) had acceptable anti S-RBD immunoglobulin G (IgG) levels after the first and second dose, respectively. Eighty patients (8.68%) got infected with COVID-19 which led to 45 (4.9%) of patients being hospitalized. None of the patients died during follow-up period. Twenty-four (10.9%) liver transplant recipients developed liver enzyme elevation, and increased serum creatinine was observed in 86 (13.5%) kidney transplant patients. Two patients experienced biopsy-proven rejection without any graft loss.ConclusionOur study revealed that humoral response rate of solid organ transplant recipients to Sinopharm vaccine was low.

RESUMEN

BACKGROUND: Hepatic steatosis is an increasing complication in liver transplant recipients. Currently, there is no pharmacologic therapy for treatment of hepatic steatosis after liver transplantation. The aim of this study was to determine the association between use of angiotensin receptor blockers (ARB) and hepatic steatosis in liver transplant recipients. METHODS: We conducted a case-control analysis on data from Shiraz Liver Transplant Registry. Liver transplant recipients with and without hepatic steatosis were compared for risk factors including use of ARB. RESULTS: A total of 103 liver transplant recipients were included in the study. Thirty five patients treated with ARB and 68 patients (66%) did not receive these medications. In univariate analysis, ARB use (P = 0.002), serum triglyceride (P = 0.006), weight after liver transplantation (P = 0.011) and etiology of liver disease (P = 0.008) were associated with hepatic steatosis after liver transplantation. In multivariate regression analysis, ARB use was associated with lower likelihood of hepatic steatosis in liver transplant recipients (OR = 0.303, 95% CI: 0.117-0.784; P = 0.014). Mean duration of ARB use (P = 0.024) and mean cumulative daily dose of ARB (P = 0.015) were significantly lower in patients with hepatic steatosis. CONCLUSION: Our study showed that ARB use was associated with reduced incidence of hepatic steatosis in liver transplant recipients.

RESUMEN

BACKGROUND: Children receive transplants at a younger age, and the period of immunosuppression therapy may extend over decades. However, immunosuppression seems to be responsible for long-term mortality and morbidity. Pediatric liver transplant recipients can benefit from achieving immune tolerance and the opportunity of freedom from lifelong immunosuppression. This study aimed to investigate the frequency of prope tolerance among pediatric liver transplant recipients and the characteristics of these patients. METHODS: In this retrospective cohort study of pediatric liver transplant recipients, the medical records of transplant recipients treated at Shiraz Organ Transplant Center between 1994 and 2017 were reviewed. Prope tolerance was defined as normal laboratory values and stable clinical status on low-dose monotherapy. Children treated with low-dose monotherapy were categorized as the prope tolerant group. We compared the characteristics of prope tolerant recipients on low-dose monotherapy with patients on standard immunosuppression, i.e. full-dose tacrolimus plus steroids and mycophenolate mofetil. The data were analyzed with the t-test, chi-squared test, and a Cox proportional hazard model at a 5% significance level in SPSS software version 16. RESULTS: A total of 585 children with a mean age of 8.32 ± 5.23 years were enrolled. 341 patients were categorized as prope tolerant and 244 comprised the full immunosuppression regimen group. Mean age at transplantation and rejection frequency were lower in the prope tolerant group (p < 0.001, p < 0.001). Based on the underlying diseases, metabolic/genetic, biliary tract, and cryptogenic liver diseases were significantly more prevalent in the prope tolerant group (p < 0.001). However, autoimmune liver disease was found to be more prevalent in the full immunosuppression regimen group. Also, those who received living organs (p = 0.001) and recipients of organs from female donors had a greater likelihood of achieving prope tolerant. According to the multiple Cox regression results, age at transplantation (p = 0.022), rejection frequency (p < 0.001), and autoimmune liver diseases (p = 0.028) had a prognostic effect on prope tolerance. CONCLUSION: Factors as underlying disease, age at transplantation, and rejection frequency were factors that were predictive of prope tolerance in this sample of children. However, the risk of rejection should be considered during the tapering period.

RESUMEN

BACKGROUND: For the first time, we aimed to determine the epidemiology and associated factors of obesity and hypertension among children of military families in our region. METHODS: In this multi-centered study, children between the ages of 5 to 12 years old, entered the study. Data on baseline and clinical characteristics, history of disease and anthropometric measurements, were collected. RESULTS: Among 504 children, 44.2% were males. Mean (SD) age of participants was 7.9 ± 1.9 years. Overall, 5% were obese and 9.9% were overweight. In total, 16.3% had elevated BP, 12.5% had stage one and 0.2% had stage two hypertension. Age (beta = 0.306, OR = 1.35, 95% CI:1.14-1.61), obesity/overweight (OR = 5.58, 95% CI:2.59-12.0), history of hypertension in mother (OR = 43.24, 95% CI:5.99-312.11), low birth weight (OR = 7.96, 95% CI:2.59-12.0), physical activity (OR = 0.27, 95% CI:0.10-0.72), and consumption of fast food more than once a week (OR = 3.36, 95% CI:1.82-6.19), were associated with risk of hypertension. Furthermore, age (beta = 0.346, OR = 1.41, 95% CI:1.21-1.64), history of childhood obesity in the father (OR = 3.78, 95% CI: 1.77-8.06) and mother (OR = 2.44, 95% CI:1.07-5.56), and physical activity (OR = 0.27, 95% CI:0.11-0.66), were associated with obesity. CONCLUSION: Age, obesity/overweight, history of hypertension in the mother, birth weight, physical activity, and consumption of fast food, were associated with risk of hypertension. Moreover, age, history of childhood obesity in parents, and physical activity, were associated with obesity. Furthermore, we found that school-age children in military families have higher rates of hypertension and overweight compared to other reports from our region.

RESUMEN

INTRODUCTION: Fungal co-infections are considered an important complication in hospitalized patients with SARS-CoV-2 that can be attributed to disease aggravation, increased mortality, and poor outcomes. This study was conducted to determine the species distribution and antifungal susceptibility patterns of Candida isolates from hospitalized COVID-19 patients in Shiraz, Iran, in addition to associated risk factors and outcomes of co-infections with Candida species. MATERIALS AND METHODS: In this single-center study, a total of 106 hospitalized COVID-19 patients were evaluated for clinical characteristics and outcomes. Species identification was performed by ITS1-5.8S-ITS2 gene sequencing. Antifungal susceptibility testing to fluconazole, itraconazole, voriconazole, posaconazole, caspofungin, amphotericin B, and nystatin was determined according to the M27-A3/S4 CLSI protocol. RESULTS: Candida species were recovered from 48% (51/106) of hospitalized COVID-19 patients. Statistical analysis showed that patients who had heart failure, bacterial co-infection, and were receiving empirical antifungal therapy had a higher risk of developing Candida co-infection. In total, 71 Candida isolates were recovered, of which C. albicans (69%) was the most prevalent isolate. The majority of the Candida isolates were susceptible to all classes of tested antifungal drugs. DISCUSSION: Our results elucidate a high rate of Candida co-infections among hospitalized COVID-19 patients. Comorbidities such as heart failure, HTN, COPD, bacterial infections as well as therapeutic interventions including catheterization, mechanical ventilation, and ICU admission increased the risk of Candida spp. isolation from the bloodstream, respiratory tract and urine samples, which led to a higher in-hospital mortality rate. Additionally, obtained data clarified that empirical antifungal therapy was not as successful as anticipated.

RESUMEN

OBJECTIVES: Coronavirus disease 2019 has resulted in significant morbidities and mortalities in nearly all parts ofthe world. There remain major concerns about management, timing, and safety of liver transplant in patients who have recovered from COVID-19. We aimed to study the clinical course and outcomes of patients with liver cirrhosis who recovered from COVID-19 and underwent liver transplant from deceased donors. MATERIALS AND METHODS: A retrospective study was conducted on liver transplant recipients who underwent liver transplant from April 1, 2020, to January 30, 2021. We evaluated all recipients of liver transplantfrom deceased donors during this period in the COVID-19 pandemic. RESULTS: There were 14 patients with decompensated liver cirrhosis who had recovered from COVID-19 as documented by reverse transcription-polymerase chain reaction test for SARS-CoV-2. Mean duration from COVID-19 to transplant surgery was 56.14 ± 29.96 days. Mortality occurred in 3 patients, and of whom 2 had been hospitalized and received medications for COVID-19 before transplant. Five patients had positive reverse transcription-polymerase chain reaction results for SARS-CoV-2 after liver transplant. CONCLUSIONS: This is a large reported series of patients with liver cirrhosis who have received liver transplant after recovery from COVID-19. We provided evidence that liver transplant from deceased donors should be considered in patients recovered from COVID-19, especially in those with deterioration of clinical status.

RESUMEN

Passenger lymphocyte syndrome (PLS) is a well-described phenomenon causing immune hemolytic anemia, mostly in non-ABO identical transplantations. The syndrome occurs when donor lymphocytes produce antibodies against the recipient's red blood cells. Although the syndrome is usually self-limited, further management with blood transfusions, immunosuppression, or plasmapheresis might be needed. A 23-year-old female with AB+ blood group underwent small intestine transplantation from a deceased donor with O+ blood group. She received rituximab, thymoglobin, and methylprednisolone as immunosuppressive induction. In the 9th postoperation day, she developed hemolysis which was primarily managed with blood transfusions and finally ceased by plasmapheresis and intravenous immunoglobulin. Few cases of PLS have been previously described in intestinal transplantation recipients. Correct diagnosis and management prevents severe hemolysis outcomes. Previous cases have been successfully treated with a combination of immune suppression, plasma exchange, and transfusions.

RESUMEN

BACKGROUND & AIMS: Delirium is a prevalent complication of liver transplantation (LT). It may enhance the risk of morbidity and mortality. Taurine is considered to have antioxidant and neuroprotective activities. The aim of this study was to evaluate taurine supplementation effect on post-LT delirium. METHODS: Patients older than 18 years old who had received LT in Abu-Ali Sina transplantation center in Shiraz, Iran from September 2020 to June 2021, were enrolled in this double-blinded randomized clinical trial. Exclusion criteria was known hypersensitivity to taurine, pregnancy or breast-feeding and death within 72 h post-LT. Patients were randomly divided into two groups, each received 2 g/day placebo or taurine from the first day post-LT for 30 days. Delirium was assessed using Confusion Assessment Method-Intensive Care Unit (CAM-ICU). Mortality and rejection rates and length of Intensive Transplantation Unit (ITU) and hospital stays were evaluated within one month after transplantation. RESULTS: Two hundred and seven patients were divided into two groups. Twenty-eight and 23 patients were excluded due to their refuse to participate in the study and death within 72 h post-LT, respectively. Delirium rate within the first month was 23.08% and was significantly lower in taurine group (9.46%) compared with placebo (35.36%, P = 0.012). Length of ITU stay was significantly higher among delirious patients (P = 0.015) in this analysis. CONCLUSION: we reached to the result that taurine can prevent post-LT delirium, dramatically. Placebo receiving and longer stay in ITU were the only independent risk factors in this trial. REGISTRATION NUMBER OF CLINICAL TRIAL: The study was registered at the Iranian Registry of Clinical Trials (IRCT20200312046755N1; http://www.irct.ir/).

RESUMEN

BACKGROUND: Many regions of the world, especially middle- and low-income countries, lack facilities for home parenteral nutrition and thus cannot follow existing guidelines for intestinal transplantation. Herein, we report our experiences with treatment protocols, intraoperative management, and early postoperative outcomes among patients undergoing either isolated intestinal transplantation or multivisceral transplantation in our center. METHODS: During a 1-year period from March 2019 to March 2020, a total of 9 intestinal transplantations including 6 isolated intestinal transplantations and 3 multivisceral transplantations were performed in our center. We reported on donor selection strategies, surgical treatment, anesthesiology care and protocols for total parenteral nutrition, immunosuppression regimen, and pathology evaluation. RESULTS: Mean (standard deviation) age of patients was 37.5 ± 12.5 years. The majority of patients were females (7/9). The median (interquartile range) waiting time for patients from diagnosis to transplantation was 79 (34, 164) days. Our 7-day survey of the amount of fluid therapy after transplantation revealed that the greatest need for fluid therapy was seen on the second postoperative day. After transplantation, 2 patients showed a total of 3 episodes of severe rejection, 1 of which was antibody-mediated. The 1-year survival was 66.6% and the 2-year survival was 44.5% in our study population. The median (interquartile range) time to death was 157 (26.5, 382) days. The most common cause of death was sepsis in our series (3/5). CONCLUSION: Acceptable outcomes can be obtained with intestinal transplantation in countries without home parenteral nutrition by application of specific treatment protocols.

RESUMEN

PURPOSE OF REVIEW: The surgical management of enteroatmospheric fistula (EAF) in patients with intestinal failure represents a major challenge for a surgical team and requires proficiency in sepsis management, nutritional support and prehabilitation, beside expertise in visceral and abdominal wall surgery. This review provides an update on the current recommendations and evidence. RECENT FINDINGS: Reconstructive surgery should be performed at a minimum of 6-12 months after last laparotomy. Isolation techniques and new occlusion devices may accelerate spontaneous EAF closure in selected cases. Chyme reinfusion supports enteral and parenteral nutrition. Stapler anastomosis and failure to close the fascia increase the risk of EAF recurrence. Posterior component separation, intraoperative fascial tension and biological meshes may be used to accommodate fascial closure. SUMMARY: Timing of reconstructive surgery and previous optimal conservative treatment is vital for favorable outcomes. Wound conditions, nutritional support and general patient status should be optimal before attempting a definitive fistula takedown. Single stage procedures with autologous gut reconstruction and abdominal wall reconstruction can be complex but well tolerated.
