RESUMO
Wilkie's syndrome, also known as Superior mesenteric artery (SMA) syndrome, is characterized by intestinal obstruction due to aortomesenteric duodenal compression caused by the reduction of the normal angle between (38-65º) to <25º or to a distance <8mm. The clinical presentation is usually non-specific (dyspepsia, postprandial abdominal pain) but sometimes presented as an acute intestinal obstruction syndrome (nausea, vomiting, gastric dilatation and abdominal distention). In this study, we report the case of a 22-year-old patient with a BMI of 16.5 who presented to the emergency room with acute intestinal obstruction caused by SAMS. He presented with massive gastric dilation that caused ischaemic necrosis of the gastric mucosa with subsequent perforation. It should be noted that only one case associated with Wilkie syndrome has been described in the literature. Therefore, given the rare incidence of complications associated with this syndrome and the favourable prognosis with conservative management, surgery is usually the last line of treatment. However, we must not forget that when necrosis appears, it is often extensive and requires urgent surgical treatment in most cases.
RESUMO
Melanoma is a cancer that frequently metastasises to the small bowel, but most cases are asymptomatic and are diagnosed postmortem. Therefore, CT and PET CT cannot detect all lesions and conventional endoscopic study only detects 10-20% of lesions. In this study, we present the case of a 68-year-old patient with a history of cutaneous melanoma and a diagnosis of intestinal melanoma. Thanks to capsule endoscopy, two lesions compatible with cutaneous melanoma metastasis to the small bowel were detected, allowing a much more effective surgical planning. Capsule endoscopy is an innovative technique that improves preoperative diagnosis, as it is able to detect bowel segments that cannot be inspected by conventional endoscopy. It also has a better resolution than conventional CT, improving sensitivity in the detection of lesions.

INTRODUCTION: Satisfactory outcomes in a series of liver transplantations (LT) with octogenarian liver grafts have been reported, as well as several cases of LT using nonagenarian liver grafts with short follow-up. METHODS: From October 2013 to December 2019, we performed 426 LT. Six LTs used nonagenarian livers (case group) and 49 used octogenarian livers (control group). A comparative analysis was performed between groups. Median donor age was significantly higher in the nonagenarian group than in the octogenarian group (90.6 years versus 83.4 years; (P < .001). There was a significant difference in LT indications (P = .026) between the groups, but not in perioperative recipient variables, morbidity, or mortality. The 1-, 3-, and 5-year patient survival rates were 67.7% in the recipients of nonagenarian livers and 85.7%, 78.0%, and 74.4%, respectively, in the recipients of octogenarian livers (P = .631). The 1-, 3-, and 5-year graft survival rates were 66.7% in the recipients of nonagenarian livers and 81.3%, 73.8%, and 70.3%, respectively, in the recipients of octogenarian livers (P = .745). CONCLUSIONS: The results of LT with nonagenarian liver grafts are not significantly different from those obtained with octogenarian donors, taking into consideration the small sample size and careful selection of donors and adequate donor-recipient matching.

Intraductal papillary neoplasm of the bile duct (IPNB) or biliary papillomatosis (BP) is a premalignant entity with high risk of malignant transformation. When the disease extends widely from the intrahepatic to the extrahepatic biliary tree, liver transplantation (LT) is the only option available. We present the case of a 43-year-old male who was admitted in our hospital with an acute cholangitis. He was diagnosed of diffuse biliary and pancreatic papillomatosis. Firstly, we performed a cephalic pancreaticoduodenectomy, then we completed a total pancreatectomy, and finally, after confirming the absence of foci of carcinoma infiltration or lymph nodes involvement, a LT was performed. Foci of carcinoma infiltration or lymph nodes involvement in the liver were not found. After a two-year follow-up the patient developed liver recurrence and the biopsy showed a biliary adenocarcinoma. In 2010, Vibert et al. published a series of three cases concluding that in the absence of invasive carcinoma and positive lymph nodes, LT can be performed with success. The present case is the first to describe recurrence of the disease after LT in the absence of invasive carcinoma and positive lymph nodes in the literature. When the disease affects widely the entire biliary duct, small micro-invasive foci may not be detected. Nevertheless, although we know that it is a recurrent entity, the pathogenesis is unknown, and we do not know if it is possible that papillomatosis recurs over the new liver.

Primary hyperoxaluria (PH) is a metabolic liver disease with an autosomal recessive inheritance that results in oxalate overproduction that cannot be metabolized by the liver. Urinary excretion of oxalate results in lithiasis and nephrocalcinosis leading to a progressive loss of renal function that often requires renal replacement therapy despite medical treatment. Type 1 PH is the most common form and is due to a deficiency in the alanine-glycolate aminotransferase enzyme found in hepatic peroxisomes. Therefore, a liver-kidney simultaneous transplant (LKST) is the definitive treatment for end-stage renal disease (ESRD) patients. However, some studies suggest that the morbidity and mortality rates are greater when this procedure is performed instead of only a kidney transplant (IKT). Herein, we report five patients with PH and a mean glomerular filtration rate of 20.2 ± 1.3 ml/min/1.73 m2 who received a LKST between 1999 and 2015 at the Hospital Universitario 12 de Octubre. Recurrence and liver or kidney graft loss was not observed during the postoperative period and only one case of late acute rejection without graft loss was diagnosed. The recipient survival rate was 100% with a median follow up of 84 months. As LKST is a curative and safe procedure with a low mortality and high survival rate, it must be considered as the treatment of choice in adults with HP and ESRD.

INTRODUCTION: Controversy exists in the literature as to the best technique for pancreaticoduodenectomy (PD), whether pyloric preservation (PP-CPD) or Whipple's technique (with antrectomy [W-CPD]), the former being associated with a higher frequency of delayed gastric emptying (DGE). METHODS: Retrospective and comparative study between PP-CPD technique (n = 124 patients) and W-CPD technique (n = 126 patients), in patients who were operated for tumors of the pancreatic head and periampullary region between the period 2012 and 2023. RESULTS: Surgical time was longer, although not significant, with the W-CPD technique. Pancreatic and peripancreatic tumor invasion (p = 0.031) and number of lymph nodes resected (p < 0.0001) reached statistical significance in W-CPD, although there was no significant difference between the groups in terms of lymph node tumor invasion. Regarding postoperative morbimortality (medical complications, postoperative pancreatic fistula [POPF], hemorrhage, RVG, re-interventions, in-hospital mortality, Clavien-Dindo complications), ICU and hospital stay, no statistically significant differences were observed between the groups. During follow-up, no significant differences were observed between the groups for morbidity and mortality at 90 days and survival at 1, 3 and 5 years. Binary logistic regression analysis for DGE showed that binary relevant POPF grade B/C was a significant risk factor for DGE. CONCLUSIONS: Postoperative morbidity and mortality and long-term survival were not significantly different with PP-CPD and W-CPD, but POPF grade B/C was a risk factor for DGE grade C.

INTRODUCTION: The standard treatment for intrahepatic cholangiocarcinoma (iCCA) and mixed hepatocellular-cholangiocarcinoma (HCC-CC) is surgical resection, nevertheless, recent studies show adequate survival rates in selected patients with iCCA or HCC-CC undergoing liver transplantation (LT). METHODS: A retrospective cohort study was design including all patients undergoing LT at our center between January, 2006 and December, 2019 with incidentally diagnosed iCCA or HCC-CC after pathological examination of the explanted liver (n = 13). RESULTS: There were no iCCA or HCC-CC recurrences during the follow-up, and hence, there were no tumor related deaths. Global and disease-free survival were the same. The 1, 3 and 5-years patient survival were 92.3%, 76.9% and 76.9%, respectively. Survival rates in the "early-stage tumor group" at 1, 3 and 5 years were 100%, 83.3% and 83.3%, respectively, with no significant differences as compared to the "advanced-stage tumors group". No statistically significant differences in terms of 5-year survival were found when comparing tumor histology (85.7% for iCCA and 66.7% for HCC-CC). CONCLUSIONS: These results suggest that LT could be an option in patients with chronic liver disease who develop an iCCA or HCC-CC, even in highly selected advanced tumors, but we must be cautious when analyzing these results because of the small sample size of the series and its retrospective nature.

BACKGROUND: The shortage of liver grafts and subsequent waitlist mortality led us to expand the donor pool using liver grafts from older donors. AIM: To determine the incidence, outcomes, and risk factors for biliary complications (BC) in liver transplantation (LT) using liver grafts from donors aged > 70 years. METHODS: Between January 1994 and December 31, 2019, 297 LTs were performed using donors older than 70 years. After excluding 47 LT for several reasons, we divided 250 LTs into two groups, namely post-LT BC (n = 21) and without BC (n = 229). This retrospective case-control study compared both groups. RESULTS: Choledocho-choledochostomy without T-tube was the most frequent technique (76.2% in the BC group vs 92.6% in the non-BC group). Twenty-one patients (8.4%) developed BC (13 anastomotic strictures, 7 biliary leakages, and 1 non-anastomotic biliary stricture). Nine patients underwent percutaneous balloon dilation and nine required a Roux-en-Y hepaticojejunostomy because of dilation failure. The incidence of post-LT complications (graft dysfunction, rejection, renal failure, and non-BC reoperations) was similar in both groups. There were no significant differences in the patient and graft survival between the groups. Moreover, only three deaths were attributed to BC. While female donors were protective factors for BC, donor cardiac arrest was a risk factor. CONCLUSION: The incidence of BC was relatively low on using liver grafts > 70 years. It could be managed in most cases by percutaneous dilation or Roux-en-Y hepaticojejunostomy, without significant differences in the patient or graft survival between the groups.
RESUMO
INTRODUCTION: Current literature supports the claim that performing a cephalic pancreaticoduodenectomy (CPD) as treatment for pancreatic cancer (PC) is associated with an increase in median survival, both in octogenarian (≥80 years) patients as well as younger patients. METHODS: This is a retrospective and comparative trial, comparing results for CPD performed on 30 patients ≥80 years with PC and 159 patients <80 years. RESULTS: The patients in the octogenarian group showed a significantly higher rate of preoperative cardiovascular morbidity and a more aggressive tumoral behaviour, including more significant preoperative anemia, jaundice and levels of CA 19-9, higher vascular and neural invasion, and a lower rate of R0 resection despite using the same surgical technique. There were no significant differences in terms of postoperative complications. Postoperative mortality was similar in both groups (3.3% in octogenarians vs 3.1% in patients <80 years). Mortality during follow-up was mainly due to tumour recurrence, cardiovascular complications and COVID-19 in 2 elderly patients. Actuarial survival at 1, 3 and 5 years was significantly larger for patients <80 years old, as compared to octogenarians (85.9%, 61.1% and 39.2% versus 72.7%, 28.9% and 9.6%, respectively; P = 0.001). The presence of a pancreatic fistula and not using external Wirsung stenting were significantly associated with 90-day postoperative mortality after a CPD. CONCLUSIONS: Morbidity and mortality post-CPD is similar in octogenarians and patients younger than 80, although long-term survival is shorter due to more aggressive tumours and comorbidities associated with older age.

INTRODUCTION: There is controversy regarding the ideal pancreaticojejunostomy technique after pancreaticoduodenectomy. Many authors consider the external Wirsung stenting technique to be associated with a low incidence of fistula, morbidity and mortality. We analyse our experience with this technique. PATIENTS AND METHODS: A retrospective analysis of the morbidity and mortality of a series of 80 consecutive patients who had been treated surgically over a 6.5-year period for pancreatic head or periampullary tumors, performing pancreaticoduodenectomy and pancreaticojejunostomy with external Wirsung duct stenting. RESULTS: Mean patient age was 68.3 ± 9 years, and the resectability rate was 78%. The texture of the pancreas was soft in 51.2% of patients and hard in 48.8%. Pylorus-preserving resection was performed in 43.8%. Adenocarcinoma was the most frequent tumor (68.8%), and R0 was confirmed in 70% of patients. Biochemical fistula was observed in 11.2%, pancreatic fistula grade B in 12.5% and C in 2.5%, whereas the abdominal reoperation rate was 10%. Median postoperative hospital stay was 16 days, and postoperative and 90-day mortality was 2.5%. Delayed gastric emptying was observed in 36.3% of patients, de novo diabetes in 12.5%, and exocrine insufficiency in 3. Patient survival rates after 1, 3 and 5 years were 80.2%, 53.6% and 19.2%, respectively. CONCLUSIONS: Although our low rates of postoperative complications and mortality using external Wirsung duct stenting coincides with other more numerous recent series, it is necessary to perform a comparative analysis with other techniques, including more cases, to choose the best reconstruction technique after pancreaticoduodenectomy.

AIM: To increase the number of available grafts. METHODS: This is a single-center comparative analysis performed between April 1986 and May 2016. Two hundred and twelve liver transplantation (LT) were performed with donors ≥ 70 years old (study group). Then, we selected the first cases that were performed with donors < 70 years old immediately after the ones that were performed with donors ≥ 70 years old (control group). RESULTS: Graft and patient survivals were similar between both groups without increasing the risk of complications, especially primary non-function, vascular complications and biliary complications. We identified 5 risk factors as independent predictors of graft survival: recipient hepatitis C virus (HCV)-positivity [hazard ratio (HR) = 2.35; 95% conï¬dence interval (CI): 1.55-3.56; P = 0.00]; recipient age (HR = 1.04; 95%CI: 1.02-1.06; P = 0.00); donor age X model for end-stage liver disease (D-MELD) (HR = 1.00; 95%CI: 1.00-1.00; P = 0.00); donor value of serum glutamic-pyruvic transaminase (HR = 1.00; 95%CI: 1.00-1.00; P = 0.00); and donor value of serum sodium (HR = 0.96; 95%CI: 0.94-0.99; P = 0.00). After combining D-MELD and recipient age we obtained a new scoring system that we called DR-MELD (donor age X recipient age X MELD). Graft survival significantly decreased in patients with a DR-MELD score ≥ 75000, especially in HCV patients (77% vs 63% at 5 years in HCV-negative patients, P = 0.00; and 61% vs 25% at 5 years in HCV-positive patients; P = 0.00). CONCLUSION: A DR-MELD ≥ 75000 must be avoided in order to obtain the best results in LT with donors ≥ 70 years old.

Stenosis of the pancreaticodigestive anastomosis (pancreaticogastrostomy and pancreaticojejunostomy) is a very rare complication that usually develops several years after pancreaticoduodenectomy (PD). Only a few cases have been previously reported. We have reviewed the literature and present 2 more cases of pancreaticojejunostomy stenosis that started with episodes of recurrent acute pancreatitis 6 years and 1 year after PD, respectively. Diagnosis was based on symptoms of pancreatitis (12-15 episodes between 5 and 20 months after PD) and CT and MRI scans. Both patients were treated by resection of the pancreaticojejunostomy stenosis, including a 1-cm slice of pancreatic parenchyma in contact with the jejunum, followed by a new well-vascularized two-layer end-to-side PJ with external drainage of the Wirsung duct. Catheter drainage was exteriorized through a jejunal limb using the Witzel technique. Postsurgical course was uneventful in both cases, and after a follow-up period of 3 and 2.5 years, respectively, the patients remain asymptomatic but with endocrine and exocrine insufficiency. Resection of the PJ and construction of a new PJ with external stent drainage of the Wirsung duct is our preferred surgical option in the rare cases of PJ stenosis after a Whipple procedure.

INTRODUCTION: Simultaneous pancreas-kidney transplantation (SPKT) constitutes the therapy of choice for diabetes type1 or type2 associated with end-stage renal disease, because is the only proven method to restore normo-glicemic control in the diabetic patient. METHODS: Retrospective and descriptive study of a series of 175 patients who underwent SPKT from March 1995 to April 2016. We analyze donor and recipient characteristics, perioperative variables and immunosuppression, post-transplant morbi-mortality, patient and graft survival, and risk factors related with patient and graft survival. RESULTS: Median age of the donors was 28years and mean age of recipients was 38.8±7.3years, being 103 males and 72 females. Enteric drainage of the exocrine pancreas was performed in 113 patients and bladder drainage in 62. Regarding post-transplant complications, the overall rate of infections was 70.3%; graft pancreatitis 26.3%; intraabdominal bleeding 17.7%; graft thrombosis 12.6%; and overall pancreas graft rejection 10.9%. The causes of mortality were mainly cardiovascular and infectious complications. Patient survival at 1, 3 and 5-year were 95.4%, 93% and 92.4%, respectively, and pancreas graft survival at 1, 3 and 5-year were 81.6%, 77.9% y 72.3%, respectively. CONCLUSIONS: In our 20-year experience of simultaneous pancreas-kidney transplantation, the morbidity rate, and 5-year patient and pancreas graft survivals were similar to those previously reported from the international pancreas transplant registries.
