Background: The increase of quality of life, the improvement in the perioperative care programs, the use of the frailty index, and the surgical innovation has allowed to access of complex abdominal surgery for elderly patients like liver resection. Despite of this, in patients aged 70 or older there is a limitation for the implementation ERAS protocolos. The aim of this study is to evaluate the implementation ERAS protocol on elderly patients (≥70 years) undergoing liver resection., Methods: A prospective cohort study of patients who underwent liver resection from December 2017 to December 2019 with an ERAS program. We compare the outcomes in patients ≥70 years (G ≥ 70) versus <70 years (G < 70). The frailty was measured with the Physical Frailty Phenotype score., Results: A total of 101 patients were included. 32 of these (31.6%) were patients ≥70 years. 90% of the both groups had performed >70% of the ERAS. Oral diet tolerance and mobilization on the first postoperative day were quicker in <70 years group. The hospital stay was similar in both groups (3.07days/2.7days). Morbidity and mortality were similar; Clavien I-II(G ≥ 70:41% vs G < 70:30,5%) and Clavien ≥ III (G ≥ 70:6% vs G < 70:8.5%), like hospital readmissions. Mortality was <1%. ERAS protocol compliance was associated with a decrease in complications (ERAS < 70%:80% vs ERAS > 90%:20%; p = 0.02) and decrease in severity of complications in both study groups. Frailty was found in 6% of the elderly group; the only patient who died had a frailty index of 4., Conclusion: Implementation of ERAS protocol for elderly patients is possible, with major improvements in perioperative outcomes, without an increase in morbidity, mortality neither readmissions., (Copyright © 2021 AEC.

Complete liver mobilization for major resections sometimes causes liver tilting due to the release of the suspensory elements of the liver. Rarely this may take to a liver abnormal position with acute obstruction to venous flow at the suprahepatic level (Budd-Chiari syndrome). To avoid this complication, techniques such as post-operative stent implantation have been described. The case of a patient who underwent a complete mobilization of the liver for resection of the inferior venous cava and a right renal tumor, was reported. After that, an acute Budd-Chiari Syndrome was observed caused of the liver malposition, which was solved with the placement of two silicone prostheses in the liver cell., (Copyright © 2021 AEC.

Introduction: Obtaining tumor-free margins during breast conservative surgery (BCS) is essential to avoid local recurrence and frequently requires reoperation. Radiofrequency ablation (RFA) of surgical margins after lumpectomy seems to be a helpful tool to avoid reoperations, but evidence is insufficient. This study analyzes the efficacy and safety of RFA after BCS to obtain free surgical margins., Methods: Non-randomized experimental study performed in an intervention group of 40 patients assigned to receive RFA after lumpectomy and successive resection of surgical margins, and a historical control group of 40 patients treated with BCS alone. In the intervention group, the RFA effect on tumor cell viability in the surgical margins was analyzed. Also, reoperation rate, complications and cosmetic results were compared in both groups., Results: A total of 240 excised margins were analyzed after RFA, obtaining a high number of tumor-free margins. Compared to the control group, the reoperation rate decreased significantly (0% vs 12%; P=.02), without differences in terms of postoperative complications (10% vs 5%; P=.67) or cosmetic results (excellent or good 92.5% vs 95%; P=.3)., Conclusions: RFA after lumpectomy is a reliable, safe and successful procedure to obtain tumor-free surgical margins and to decrease the reoperation rate without affecting complications or compromising cosmetic results., (Copyright © 2020 AEC.

Objective: The aim of this study is to analyze the increasing need of radiological support in the diagnosis of acute appendicitis (AA), the clinical repercussions associated, and the parameters of diagnostic accuracy of ultrasound and computed tomography (CT) scan for AA., Material and Methods: Observational and analytical study. Cohort, patients operated on for suspected AA at a tertiary referral hospital. Pregnancy and <14 years were exclusion criteria., Study Group: January 2010-December 2011 (n1=419)., Control Group: set of patients aged 18 to 65 years old operated between October 2001-September 2003 (n2=237). Variables analyzed in both groups: 1) percentage of radiological support for diagnosis of acute appendicitis; 2) sensitivity and positive predictive value (PPV) of ultrasound and CT scan; 3) rate of surgical explorations with negative result or with diagnosis other than acute appendicitis., Statistical Analysis: SPSS software, χ(2) test, statistical significance accepted with P<.05, 95% confidence interval (95% CI) for the odds ratio (OR)., Results: Age, gender, percentage of atypical locations and gangrenous/perforated episodes were similar in both groups. The number of radiological examinations needed for diagnosis was significantly higher in the study group (78.8% vs. 30.4%, P<.0,000). Sensitivity was significantly superior for CT than for ultrasound scan (97% vs. 86%), but PPV was similar in both tests (92% vs. 94%). Surgical exploration percent values with diagnosis of acute appendicitis was significantly higher in the study group (94.5% vs. 88.6%; P<.006, OR 2.2; CI 95% 1.25-4)., Conclusions: CT and ultrasound scan are excellent diagnostic tools for acute appendicitis, and have contributed to a significant increase in surgical explorations with correct diagnosis., (Copyright © 2012 AEC.

Unlabelled: A study was made of the arterial complications documented in 400 transplants performed between 1997 and 2006. The patients were divided into two groups according to the type of treatment provided. Group I: invasive management (arterial treatment or re-transplant), and Group II: conservative or symptomatic management. The impact of management upon survival and biliary complications was analysed., Results: There were 18 arterial complications (4.5%): 10 early (7 thromboses and 3 stenoses) and 8 late (5 thromboses and 3 stenoses). Ninety percent of the early complications were subjected to invasive management (4 emergency thrombectomies, 1 re-transplant and 3 angioplasties), while 25% of the late complications were treated in the form of re-transplant and the remaining 75% were subjected to symptomatic treatment. Survival after 12 and 60 months was lower in Group II (57% and 42%) than in Group I (90% and 68%), although without reaching statistical significance. The overall biliary complications rate among the patients with arterial thrombosis was 50%. The rate was significantly lower in Group I than in Group II (10% versus 71%) (P<04)., Conclusions: Invasive management of the arterial complications of liver transplantation is associated with longer short-term survival and significantly fewer biliary complications. In our experience, patients benefit from an early diagnosis and aggressive management of complications of this kind., (Copyright 2009 AEC. Published by Elsevier Espana. All rights reserved.)

Recent advances in liver surgery have reduced post-hepatectomy mortality to less than 5% in most units specialized in hepato-pancreatic-biliary surgery. Possibly, the single most important factor contributing to these improved results has been the reduction in intraoperative bleeding during liver parenchymal transection. Liver transection is the most risky part of the intervention due to the risk of massive hemorrhage. Some technological advances and refinements to the surgical technique have contributed to making this critical phase of liver surgery safer. Among these advances, the most notable are detailed knowledge of the surgical anatomy of the liver, vascular control techniques and methods of liver parenchymal transection. The present review describes current transection techniques, as well as their advantages and disadvantages. Until there is solid evidence on the best method, the choice of technique and instrument for liver transection depends mainly on the surgeon's personal preference. Nevertheless, some factors can influence the choice of method, such as the surgeon's experience, anesthetic management, type of hepatectomy (central, peripheral), type of approach (open, laparoscopic), quality of the liver (normal, cirrhotic, steatotic) and the availability of the instruments in the center.

Objectives: To assess the incidence and type of biliary complications in liver transplantation after biliary reconstruction with or without a biliary tutor., Material and Method: A prospective, non-randomized study of 128 consecutive patients undergoing elective liver transplantation was performed. Retransplantations, emergency transplantations, hepaticojejunostomy and patients who died within 3 months of causes other than biliary complications were excluded. Group I (n = 64) underwent termino-terminal choledochocholedochostomy with a Kehr tube and group II (n = 64) underwent choledochocholedochostomy without Kehr tube. Complications, therapeutic procedures, reoperations and survival free of biliary complications were analyzed., Results: The overall rate of biliary complications was 15% (17% in group I and 14% in group II). Types of complication (overall and in groups I and II, respectively) consisted of fistulas 4% (6% vs. 3%), stenosis 8% (4% vs. 12%), and Kehr dysfunction 3%. The mean number of therapeutic procedures, including endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, trans-Kehr cholangiography and drainage of collections, was 2.1 vs. 2 per complicated patient. The overall reoperation rate was 5% (2% vs. 9%) (p < 0.05). One-year survival free of biliary complications was 85% vs. 82% (Log Rank = 0.5)., Conclusions: No statistically significant differences were found in complications after choledocho-choledocho anastomosis with or without a biliary tutor. However, the patient group that did not receive a biliary tutor required more complex procedures for treatment of complications, as well as a greater number of reoperations.

Introduction: Hepatocellular carcinoma is a frequent complication of cirrhosis. Liver transplantation is a valid therapeutic option for this disease providing that certain morphologic selection criteria (Milan criteria) are fulfilled., Objective: To evaluate the accuracy of pretransplantation imaging examinations in the detection and characterization of neoplastic lesions in cirrhotic candidates for liver transplantation., Patients and Method: We performed a retrospective study of 250 cirrhotic patients who underwent liver transplantation. The preoperative radiological diagnosis was compared with the definitive pathological diagnosis, allowing the diagnostic sensitivity of the different techniques, as well as the degree of agreement between pre- and postoperative tumoral staging, to be identified., Results: Analysis of 250 specimens from total hepatectomy identified 58 patients with hepatic tumors, with a total of 136 nodules. Fifty-three patients had hepatocarcinoma, nine of which were found incidentally. There were six radiological false positive diagnoses. Sixty-two percent of patients with hepatocarcinoma had multiple lesions. The most sensitive technique for the diagnosis of tumors smaller than 1 cm was magnetic resonance imaging. Agreement between pre- and postoperative staging was found in only 63.6% of cases; consequently, 43% of the patients who exceeded the Milan criteria (20% stage T3 and 23% stage T4a) underwent transplantation., Conclusions: Currently used imaging techniques lead to a substantial proportion of incorrect stagings in terms of the size and number of lesions in cirrhotic patients.

Endometriosis, defined as the presence of endometrial tissue outside the uterine cavity, is most frequently located in the pelvic organs. Hepatic endometriosis is extremely rare, and only 12 cases have previously been reported. A wide variety of symptoms have been described, from asymptomatic masses (incidental findings) to acute abdomen. The diagnostic method of choice is abdominal CT, which should always be used in the differential diagnosis of cystic liver masses. Because of the high percentage of malignant transformation, the first-line treatment is surgical resection with adequate safety margins. We report a case of in situ adenocarcinoma arising in a hepatic endometrioma, which was treated with right hepatectomy.
