Multicentre evaluation of case volume in minimally invasive hepatectomy.

BACKGROUND: Surgical outcomes may be associated with hospital volume and the influence of volume on minimally invasive liver surgery (MILS) is not known. METHODS: Patients entered into the prospective registry of the Italian Group of MILS from 2014 to 2018 were considered. Only centres with an accrual period of at least 12 months and stable MILS activity during the enrolment period were included. Case volume was defined by the mean number of minimally invasive liver resections performed per month (MILS/month). RESULTS: A total of 2225 MILS operations were undertaken by 46 centres; nine centres performed more than two MILS/month (1376 patients) and 37 centres carried out two or fewer MILS/month (849 patients). The proportion of resections of anterolateral segments decreased with case volume, whereas that of major hepatectomies increased. Left lateral sectionectomies and resections of anterolateral segments had similar outcome in the two groups. Resections of posterosuperior segments and major hepatectomies had higher overall and severe morbidity rates in centres performing two or fewer MILS/month than in those undertaking a larger number (posterosuperior segments resections: overall morbidity 30·4 versus 18·7 per cent respectively, and severe morbidity 9·9 versus 4·0 per cent; left hepatectomy: 46 versus 22 per cent, and 19 versus 5 per cent; right hepatectomy: 42 versus 34 per cent, and 25 versus 15 per cent). CONCLUSION: A volume-outcome association existed for minimally invasive hepatectomy. Complex and major resections may be best managed in high-volume centres.

ANTECEDENTES: Los resultados quirúrgicos pueden estar relacionados con el volumen de casos del hospital, pero no se conoce la influencia en la cirugía mínimamente invasiva del hígado (minimally­invasive liver surgery, MILS). MÉTODOS: Se incluyeron los pacientes registrados en el registro prospectivo del grupo italiano de MILS desde 2014 a 2018. Solo se consideraron centros con extensión de ≥ 12 meses y actividad estable de MILS durante el periodo de reclutamiento. El volumen de casos se definió como el número de MILS efectuado por mes. RESULTADOS: Se llevaron a cabo un total de 2.225 MILS en 46 centros, 9 de ellos con > 2 MILS/mes (n = 1.376 pacientes) y 37 centros con ≤ 2 MILS/mes (n = 849). La proporción de resecciones de segmentos anterolaterales disminuyó con el volumen de casos, mientras que la proporción de hepatectomías mayores aumentó. Los resultados para ambos grupos fueron similares en las seccionectomías lateral izquierda y en las resecciones del segmento anterolateral. Las resecciones del segmento posterosuperior y las hepatectomías mayores presentaron tasas más altas de morbilidad global y morbilidad grave en centros que realizaban ≤ 2 MILS/mes que en los que realizaban > 2 MILS/mes (resecciones del segmento posterosuperior, morbilidad global 30,4 versus 18,7%, morbilidad grave 9,9 versus 4,0%; hepatectomía izquierda, 46,2 versus 22,0%, 19,2 versus 5,5%; hepatectomía derecha, 41,7 versus 33,8%, 25,0 versus 14.9%). CONCLUSIÓN: Se observó una asociación volumen­resultado para la resección hepática mínimamente invasiva. Las resecciones complejas y mayores se pueden manejar mejor en centros de gran volumen.

Risk-adjusted benchmarks in laparoscopic liver surgery in a national cohort.

BACKGROUND: This study aimed to assess the best achievable outcomes in laparoscopic liver resection (LLR) after risk adjustment based on surgical technical difficulty using a national registry. METHODS: LLRs registered in the Italian Group of Minimally Invasive Liver Surgery registry from November 2014 to March 2018 were considered. Benchmarks were calculated according to the Achievable Benchmark of Care (ABC™). LLRs at each centre were divided into three clusters (groups I, II and III) based on the Kawaguchi classification. ABCs for overall and major morbidity were calculated in each cluster. Multivariable analysis was used to identify independent risk factors for overall and major morbidity. Significant variables were used in further risk adjustment. RESULTS: A total of 1752 of 2263 patients fulfilled the inclusion criteria: 1096 (62·6 per cent) in group I, 435 (24·8 per cent) in group II and 221 (12·6 per cent) in group III. The ABCs for overall morbidity (7·8, 14·2 and 26·4 per cent for grades I, II and II respectively) and major morbidity (1·4, 2·2 and 5·7 per cent) increased with the difficulty of LLR. Multivariable analysis showed an increased risk of overall morbidity associated with multiple LLRs (odds ratio (OR) 1·35), simultaneous intestinal resection (OR 3·76) and cirrhosis (OR 1·83), and an increased risk of major morbidity with intestinal resection (OR 4·61). ABCs for overall and major morbidity were 14·4 and 3·2 per cent respectively for multiple LLRs, 30 and 11·1 per cent for intestinal resection, and 14·9 and 4·8 per cent for cirrhosis. CONCLUSION: Overall morbidity benchmarks for LLR ranged from 7·8 to 26·4 per cent, and those for major morbidity from 1·4 to 5·7 per cent, depending on complexity. Benchmark values should be adjusted according to multiple LLRs or simultaneous intestinal resection and cirrhosis.

ANTECEDENTES: Este estudio tuvo como objetivo evaluar los mejores resultados que se pueden conseguir en la resección hepática laparoscópica (laparoscopic liver resection, LLR) después del ajuste por riesgos basado en la dificultad de la técnica quirúrgica utilizando un registro nacional. MÉTODOS: Se consideraron las LLRs incluidas en el Registro del Grupo Italiano de Cirugía Hepática Mínimamente Invasiva desde 11/2014 a 03/2018. Los resultados de referencia (benchmarks) se calcularon de acuerdo con el Achievable Benchmark of Care (ABC™). Las LLRs de cada uno de los centros se dividieron en 3 grupos (Grupo I, II y III) en base a la clasificación de Kawaguchi. Se calculó el ABC de la morbilidad global y de la morbilidad mayor para cada grupo. Se realizó un análisis multivariable para identificar los factores independientes de riesgos para la morbilidad global y morbilidad mayor. Se utilizaron variables significativas para realizar ajustes de riesgo adicionales. RESULTADOS: Un total de 1.752 pacientes de los 2.263 cumplían los criterios de inclusión, de los cuales 1.096 (62,6%) se incluyeron en el Grupo I, 435 (24,8%) en el Grupo II y 221 (12,6%) en el Grupo III. El ABC de la morbilidad global (7,8%, 14,2%, 26,4%) y de la morbilidad mayor (1,4%, 2,2%, 5,7%) aumentó del Grupo I al Grupo III. El análisis multivariable mostró un incremento del riesgo para la morbilidad global asociada con múltiples LLRs (razón de oportunidades, odds ratio, OR 1,349), resección intestinal simultánea (OR 3,760) y cirrosis (OR 1,825), y para la morbilidad mayor con la resección intestinal (OR 4,606). Los ABC de la morbilidad global y morbilidad mayor fueron 14,4% y 3,2% para las LLR múltiples, 30% y 11% para la resección intestinal, y 14,9% y 4,8% para la cirrosis, respectivamente. CONCLUSIÓN: Los resultados de referencia (benchmark) para la morbilidad global y morbilidad mayor en la LLR variaron entre un 8% y un 26% y entre un 1,4% y un 5,7%, dependiendo de la complejidad. Los valores de referencia deberían ajustarse de acuerdo con la práctica de LLRs múltiples o resección intestinal simultánea y cirrosis.

Should ALPPS be Used for Liver Resection in Intermediate-Stage HCC?

BACKGROUND: Extended liver resections in patients with hepatocellular carcinoma (HCC) are problematic due to hepatitis, fibrosis, and cirrhosis. Associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) has been promoted as a novel method to induce hypertrophy for patients with extensive colorectal liver metastases, but outcomes in HCC have not been well investigated. METHODS: All patients registered in the international ALPPS Registry ( www.alpps.org ) from 2010 to 2015 were studied. Hypertrophy of the future liver remnant, perioperative morbidity and mortality, age, overall survival, and other parameters were compared between patients with HCC and patients with colorectal liver metastases (CRLM). RESULTS: The study compared 35 patients with HCC and 225 patients with CRLM. The majority of patients undergoing ALPPS for HCC fall into the intermediate-stage category of the Barcelona clinic algorithm. In this study, hypertrophy was rapid and extensive for the HCC patients, albeit lower than for the CRLM patients (47 vs. 76 %; p < 0.002). Hypertrophy showed a linear negative correlation with the degrees of fibrosis. The 90-day mortality for ALPPS used to treat HCC was almost fivefold higher than for CRLM (31 vs. 7 %; p < 0.001). Multivariate analysis showed that patients older than 61 years had a significantly reduced overall survival (p < 0.004). CONCLUSION: The ALPPS approach induces a considerable hypertrophic response in HCC patients and allows resection of intermediate-stage HCC, albeit at the cost of a 31 % perioperative mortality rate. The use of ALPPS for HCC remains prohibitive for most patients and should be performed only for a highly selected patient population younger than 60 years with low-grade fibrosis.

Surgical site and early urinary tract infections in 1000 kidney transplants with antimicrobial perioperative prophylaxis.

Surgical site infections (SSIs) and early urinary tract infections (UTIs) are well recognized postoperative kidney transplant complications. These complications seldom lead to graft loss, although they may result in significant morbidity with prolonged hospitalization. Thus, perioperative antibiotic prophylaxis (PAP) has traditionally been used in this setting. Between April 1988 and December 2012, we identified 1000 kidney transplant recipients (33 from living donors) who underwent prophylaxis with ceftriaxone before the surgical procedure. A retrospective analysis was conducted to evaluate both the incidence rate and outcome of SSIs and UTIs. Recipients who developed SSIs were also assessed to identify risk factors and potential correlations with different immunosuppressive regimens. A total of 20 SSIs (2%) and 93 UTIs (9.3%) were observed. The most significant risk factor for SSIs was urine leak (15.38%; odds ratio [OR], 12.3; P < .0001) followed by sirolimus-based maintenance immunosuppression therapy (5%; OR, 2.97; P = .04) and induction therapy with either antithymocyte globulin or basiliximab (3.18%; OR, 3.45; P = .01). Sex was identified as the only risk factor for UTI (female vs male, 17.1% vs 4.6%; P < .0001). We believe universal ceftriaxone-based prophylaxis is useful for preventing SSIs and UTIs, considering its effectiveness and safety profile.

Analysis of 80 dual-kidney transplantations: a multicenter experience.

INTRODUCTION: The use of kidneys from expanded criteria donors (ECD) is an attractive strategy to enlarge the pool of organs available for transplantation. Considering the fact that ECD organs have a reduced nephron mass, they are preferentially allocated for dual-kidney transplantation (DKT). Authors have reported excellent results of DKT when pretransplant ECD organs are evaluated for histological scores. The aim of this study was to evaluate DKT donor and recipient characteristics for comparison with DKT posttransplant outcomes versus those of recipients of single-kidney transplantations from expanded criteria (edSKT) and ideal donors (idSKT). We analyzed the potential prognostic factors involved in DKT among a population derived from three transplant centers. MATERIALS AND METHODS: Between 2001 and 2007, DKT (n = 80) were performed based upon the ECD kidney allocation assessed by biopsy. RESULTS: The average donor ages for the DKT, edSKT, and idSKT groups were 68.8 ± 7.8, 65.3 ± 7.2, and 40.1 ± 13.8 years, respectively (P < .001). The number of human leukocyte antigen mismatches was greater in the DKT group (3.1 ± 1.2, P < .05). Patient and graft 5-year survival rates were similar among DKT, edSKT, and idSKT recipients, namely, 97.5% versus 95.8% versus 96.9% and 93.7% versus 87.4% versus 86.9%, respectively. Mean serum creatinine values at discharge were lower in the DKT and idSKT recipients (1.5 ± 0.9 and 1.6 ± 0.7 mg/dL; P < .05) compared with the edSKT group (1.9 ± 0.7 mg/dL). Correlations between supposed prognostic factors and survival among the DKT group noted worse outcomes in reoperation cases (P < .05). CONCLUSION: We confirmed that DKT produced successful outcomes. An accurate surgical procedure is particularly important to try to avoid reoperations. In our experience, the use of a biopsy as an absolute criterion to allocate ECD kidneys may be too protective.

Impact of alcohol consumption on winter sports-related injuries.

INTRODUCTION: This study was carried out to evaluate data about trauma-related winter sports, including risk factors such as high speed, gender, age, alcohol consumption, details about the accident and snow conditions. METHODS: A retrospective review was conducted to determine the injury patterns and crash circumstances in holiday skiers and snowboarders. The data recorded were obtained from the database of the Pre-Hospital Emergency Registry of six skiing areas in the Dolomite mountains during the winter seasons November 2004-May 2009, injury data for major traumas from Ski Patrol Injury reports (helicopter, ambulance or ski slopes' patrol reports), and intrahospital Emergency Department data. Alcohol concentration in blood was detected in 200 individuals suffering from major trauma. RESULTS: A total of 4550 injured patients, predominantly male (69%), mean age 22 years (range 16-72), were included in the observational analysis. Knee, wrist and shoulder injuries were frequently associated with major thoracic, abdominal or head traumas (64% of cases). Suboptimal technical level, high speed, low concentration, snow or weather conditions, faulty equipment and protective devices were among the various causes of accidents. The analysis revealed that high alcohol blood concentration was present in 43% of 200 patients. CONCLUSIONS: Even though the major causes of accidents were excessive speed, excessive fatigue, technical errors and bad weather conditions, alcohol abuse was often discovered. Random sampling and a non-systematic detection of alcohol blood levels likely led to an underestimation of alcohol consumption-related injuries. It is recommended that investigations into alcoholic intoxication in injured skiers should be carried out on a large scale.

[Living donor nephrectomy: open versus laparoscopic technique].

The living donor nephrectomy has to be safe and effective, allowing a good graft function in the recipient. In the past, donor nephrectomy was performed only by open technique; more recently this nephrectomy has also been performed by laparoscopic technique. The best technique has not been established in literature. The purpose of this study is to report the results of open and laparoscopic nephrectomy in living donors. MATERIALS AND METHODS. From January 1992 to August 2008, 37 living donor nephrectomies were performed. 23 nephrectomies were achieved by laparoscopic procedure (LDN) and 14 by open technique (ODN). The 2 groups were comparable regarding both donor and recipient characteristics. RESULTS. All laparoscopic nephrectomies were successfully performed without conversion to open procedure. No donor deaths were reported in either groups. 3 complications (13%) in the LDN group and 1 (7.1%) in the ODN group (p=0.6) were observed. Mean operative time was higher in the LDN group (p<0.036). Mean warm and cold ischemia time, resumption of oral intake and hospital stay were shorter in the LDN group (p<0.04)( p<0.03) (p<0.0001), whereas the return to normal occupational life was similar (p<0.52). We had no significant differences in the surgical complication rates, graft and patient survival. CONCLUSIONS. Our experience suggests that both procedures can be used safely and efficiently, and assure a good renal function in the recipient. Laparoscopic nephrectomy, although more difficult, provides post-operative advantages. However, laparoscopic procedure must be performed by experienced centres only to prevent serious complications in the donor.

Multicenter study on double kidney transplantation.

BACKGROUND: Marginal organs not suitable for single kidney transplantation are considered for double kidney transplantation (DKT). Herein we have reviewed short and long-term outcomes of DKT over a 7-year experience. PATIENTS AND METHODS: Between 2001 and 2007, 80 DKT were performed in the transplant centers of Bologna, Parma, and Modena, Italy. Recipient mean age was 61+/-5 years. The main indications were glomerular nephropathy (n=33) and hypertensive nephroangiosclerosis (n=14). Mean HLA A, B, and DR mismatches were 3.1+/-1.2. Donor mean age was 69+/-8 years and mean creatinine clearance was 75+/-27 mL/min. Almost all kidneys were perfused with Celsior solution. Mean cold ischemia time was 17+/-4 hours and mean warm ischemia time was 41+/-17 minutes. Mean biopsy score was 4.4. Immunosuppression was based on tacrolimus (n=52) or cyclosporine (n=26). RESULTS: Fifty (62.5%) patients displayed good postoperative renal function. Thirty (37.5%) experienced acute tubular necrosis and required postoperative dialysis treatment; 8 acute rejections occurred. Urinary complications were 13.7% with 8/11 requiring surgical revision. There were 6 surgical reexplorations: intestinal perforation (n=2), bleeding (n=3), and lymphocele (n=1). Two patients lost both grafts due to vascular and infectious complications at 7 or 58 days after transplantation. Two patients underwent intraoperative transplantectomy due to massive vascular thrombosis. Four (5%) patients underwent transplantectomy of a single graft due to vascular complications (n=2), bleeding (n=1), or infectious complications (n=1). Graft and patient survivals were 95% and 100% versus 93% and 97% at 3 versus 36 months, respectively. CONCLUSIONS: DKT is a safe approach for organ shortage. The score used in this study is useful to determine whether a kidney should be refused or accepted.

[Endourological management of ureteral stenosis and vesicoureteral reflux after renal transplantation].

INTRODUCTION AND OBJECTIVES. Ureteral stenosis and vesicocoureteral reflux after renal transplantation represent a key concern because of their incidence and the associated morbidity. Prompt diagnosis and minimally invasive treatment are mandatory in immunosuppressed patients with single kidney. The aim of this study is to evaluate the success rate of the endourological techniques in the management of such complications. MATERIALS AND METHODS. Between January 1996 and December 2006, 647 kidney transplants were performed. Urinary tract continuity was re-established by ureteroneocystostomy according to Gregoir-Lich technique. We observed 13 cases of ureteral stenosis (2%) and 11 cases of symptomatic vesicoureteric reflux (1.7%). The endourogical procedure was performed in 13 patients: 5 cases of II-III grade vesicoureteric reflux, 4 early ureteral stenosis and 4 late ureteral stenosis. Patients with vesicoureteric reflux underwent endoscopic injection of macroplastique in 4 cases and Durasphere in 1. Early ureteral stenoses were treated using balloon dilation in 2 cases, balloon dilation and laser endoureterotomy in 3, ureteral stent placement in the other. Recipients with late stenosis underwent laser incision and balloon dilation in 2 cases, balloon dilation in 1 and a laser incision only in the last case. Combined antegrade and retrograde endoscopic approach was performed in 7 patients, whereas retrograde access in 1. RESULTS. Endourologic treatment was successful in 9 cases (69.2%); 2 patients required open reconstructive surgery due to endourological technique failure (early ureteropelvic junction stricture, late ureterovesical anastomotic stricture). Vesicoureteric reflux was corrected in 3 patients (60%), 2 patients underwent uretero-ureterostomy for recurrent reflux. No technique-related morbidity was observed. With a mean follow- up of 81.6 months, 8 patients show normal renal function, 5 patients have returned to haemodialysis (4 for chronic rejection, 1 for carcinoma in the graft). CONCLUSIONS. Considering their low morbidity and the satisfactory success rate, we claim that endourological procedures should be considered the preferred treatment for ureteral stenosis and vesicoureteric reflux in selected patients.

Laparoscopic donor nephrectomy: short learning curve.

INTRODUCTION: The learning curve of laparoscopic donor nephrectomy (LDN) may represent a great technical challenge at centers with low volume of living donors. The number of LDNs required to overcome the learning curve is still unclear. Here we report the modality of approach to LDN at a low-volume living donor transplant center. MATERIALS AND METHODS: We reviewed the records of two groups of donors operated by two different surgeons between January 2002 and October 2005. We compared donor hospital stay, operative time, presence of multiple renal arteries, blood loss, operative details, and complications. RESULTS: The first six operations (group A) were performed by a well-trained laparoscopic surgeon (A.P.) with a consolidated experience in the LDN procedure, attended by our training surgeon (R.D.V.) who conducted the other six cases (group B). No conversion to an open procedure was necessary and there were no major minor complications. Mean operative time was 267.5 (+/-55.9) minutes in group A and 300 (+/-43.4) minutes in group B (P = .28). Mean warm ischemia time was 125 (+/-61.6) seconds in group A and 189.2 (+/-18.6) seconds in group B (P = .035). Mean hospital stay was 5.3 days in group A and 5.6 days in group B. CONCLUSIONS: LDN can be performed safely and efficiently in transplant centers with initial experience. A collaborative approach to this difficult procedure with a surgeon skilled in donor nephrectomy minimizes the risk to the donor and reduces the learning curve.

Kidney transplantation from elderly donors: a prospective randomized study comparing celsior and UW solutions.

AIM: The aim of present study was to assess the effect of Celsior as compared with University of Wisconsin (UW) solution on immediate and long-term function of kidney transplants harvested from elderly donors. METHODS: A prospective multicenter randomized study was designed to evaluate the efficacy of Celsior versus UW solution for the clinical preservation of the kidney. Fifty renal transplants were performed from donors over 60 years old. Twenty-five kidneys were stored in Celsior and 25 in UW solution. The groups were comparable with regard to donor and recipient characteristics. Renal function outcomes were compared by evaluating delayed graft function rates, daily urinary output, as well as the evolution of mean serum creatinine at 1, 3, 5, 7, and 15 days. RESULTS: The warm ischemia time was 42.4 +/- 11 minutes among Celsior vs 46.9 +/- 17.9 minutes in the UW cohort (P = NS). The cold ischemia time was 18 +/- 4.5 hours in Celsior and 19 +/- 6.5 hours in UW (P = NS). Delayed graft function occurred in 48% of the Celsior group and in 52% of the UW group (P = NS). Mean serum creatinine levels and mean daily urinary output were also similar. One- and 5-year graft survivals of kidneys preserved with Celsior were 91.8% and 79.3% compared with 96% and 87.4% for UW without any significant statistical difference. CONCLUSIONS: Our data show that the preservation of kidneys from elderly donors in Celsior solution is equivalent to that of UW solution.

Acute diverticulitis with colon perforation in renal transplantation.

INTRODUCTION: Acute diverticulitis with colon perforation is a serious condition in transplant recipients. The aim of this study was to analyze our experience with colon perforations among 875 renal transplant recipients between January 1986 and September 2004. METHODS: Patients were analyzed by age, gender, steroid dosage, time interval from the transplantation, delay between symptoms and surgery, clinical presentation, surgical procedure, graft and patient outcomes. RESULTS: We identified 8 patients with colon perforation. The incidence of perforation was 0.9%. Mean age at the the time of perforation was 58.5 years. Fever, abdominal pain, localized or diffuse signs of peritonitis, and leukocytosis were present in 7 patients (87.5%). Three patients (37.5%) were on steroid-free immunosuppression, whereas in 2 cases (25%) the steroid dosage was >20 mg/d. The mean interval between transplantation and perforation was 4.1 years. Two episodes (25%) occurred within 1 month following transplantation and the other 6 (75%) between 1 and 15 years. The interval between the onset of symptoms and surgery was longer than 48 hours in 1 patient (12.5%). In 5 cases (62.5%), a Hartmann procedure was performed; in 2 patients (25%), a resection with primary anastomosis was preferred. The last patient had a direct suture of the colon. Mortality rate was 12.5%. At a median follow-up of 6.1 years, 6 patients (75%) are alive with 5 functioning grafts. CONCLUSIONS: Colon perforations in renal transplant recipients remain a challenging surgical problem. An aggressive diagnostic attitude and an immediate surgical treatment may contribute to significantly decrease the incidence and the mortality of this complication.

Percutaneous renal artery embolization of nonfunctioning allograft: preliminary experience.

Percutaneous renal artery embolization has been introduced as an alternative to nephrectomy for patients with a nonfunctioning allograft and Graft Intolerance Syndrome. The symptoms resulting from this syndrome include fever, local pain, hypertension, and hematuria. From April 2003 to October 2003, 5 patients were treated with this technique. The intraparenchymal renal arteries were embolized by injection of calibrated tris-acryl gelatin microspheres of increasing size (from 100-330 to 700-900 microm) and completed with the insertion of 5-mm-8-mm steel coils in the renal artery. The procedure was well tolerated in all cases; no major complications occurred. In 3 patients, the symptoms disappeared immediately. In 1 patient, it was necessary to perform a second embolization due to collateral circulation developing from a lumbar artery; this further procedure resolved the symptoms. In the last case, the patient underwent nephrectomy because of septic fever. In conclusion, patients with this syndrome refractory to medical treatment may be treated by the effective and minimally invasive procedures of percutaneous allograft artery embolization with no significant short-term or late complications.

The role of cholecystectomy in renal transplantation.

INTRODUCTION: We reviewed our clinical experience to assess the role of cholecystectomy transplant candidates pre- and posttransplantation. METHODS: Between April 1986 and December 2003, 57 (6.8%) candidates among 839 kidney transplants were found during routine pretransplant screening to show gallstones. RESULTS: Thirty nine (68.4%) symptomatic patients underwent cholecystectomy before transplantation. Among 18 (31.6%) asymptomatic patients monitored after transplantation, the 7 (39%) who developed biliary tract symptoms underwent laparoscopy or minilaparocholecystectomy without postoperative morbidity, mortality, or graft loss. CONCLUSIONS: Symptomatic gallstones have to be treated using the laparoscopic cholecystectomy or minilaparotomy technique. In asymptomatic cholelithiasis prophylactic cholecystectomy is only reserved for patients with biliary "intrinsic" risk factors. An early diagnosis and prompt surgical treatment yields good results.

Embolization of a ruptured pseudoaneurysm with massive hemorrhage following pancreas transplantation: a case report.

Pseudoaneurysm associated with an arterioenteric fistula is rare, but its clinical manifestations may represent a dramatic event that involves diagnostic and therapeutic problems. We report a case of an arterioduodenal fistula related to a ruptured pseudoaneurysm after simultaneous pancreas-kidney transplantation (SPK) with massive gastrointestinal hemorrhage treated by embolization of the Y graft. A 51-year-old man with type I diabetes and end-stage renal disease underwent SPK. No rejection episodes were documented; the patient was discharged with normal pancreatic and renal function. Two months later the patient was readmitted for an episode of massive lower digestive bleeding and hypotension. The Y-graft was embolized in order to obtain a prompt arrest of the bleeding. The procedure was successful and the patient progressively recovered. Once the hypovolemia was completely corrected, the graft was removed. An arterioenteric fistula between donor mesenteric artery and duodenum was confirmed. Few reports exist in the literature regarding the development of a pseudoaneurysm after pancreas transplantation. To our best knowledge only one case of pseudoaneurysm rupture into donor duodenum has been recently published. In our case angiography recognized the site of the pseudoaneurysm and its rupture into donor duodenum. Embolization of the Y-graft appeared the most rapid, simple, and safe approach to obtain the prompt arrest of the massive bleeding. Embolization of the Y-graft may represent a valid option in the presence of life-threatening hemorrhage.

Outcome of isolated small bowel and pancreas transplants retrieved from multiorgan donor: the in vivo technique.

Even when considering the possibility of organ rejection and the complications of immunosuppression, the risks associated with total parenteral nutrition therapy are life-threatening. Therefore, for patients with end-stage bowel disease small bowel transplantation (SBTx) is the only therapeutic option. The preferred method to procure these organs is debated, especially when, graft retrieval is associated with concurrent abdominal organ procurement of the pancreas, which shares part of the vascular inflow and outflow with the small bowel. While many surgeons procure the graft using the en bloc method, dissecting tissue at the back table, our preference is to use an in vivo technique, which results in shorter cold ischemia times and less bleeding during reperfusion of the pancreas/small bowel as well as decreased ascites production during the postoperative period and less edema and capsular bleeding of the pancreatic grafts. This article presents an analysis of 19 multiorgan cadaveric procurements using the in vivo technique with a focus on the quality of pancreas/small bowel postreperfusion properties during the first 5 to 6 postoperative months.
