RESUMO

BACKGROUND: The enhanced view totally extraperitoneal (eTEP) approach is becoming increasingly more widely accepted as a promising technique in the treatment of ventral hernia. However, evidence is still lacking regarding the perioperative, postoperative and long-term outcomes of this technique. The aim of this meta-analysis is to summarize the current available evidence regarding the perioperative and short-term outcomes of ventral hernia repair using eTEP. STUDY DESIGN: A systematic search was performed of PubMed, EMBASE, Cochrane Library and Web of Science electronic databases to identify studies on the laparoscopic or robotic-enhanced view totally extraperitoneal (eTEP) approach for the treatment of ventral hernia. A pooled meta-analysis was performed. The primary end point was focused on short-term outcomes regarding perioperative characteristics and postoperative parameters. RESULTS: A total of 13 studies were identified involving 918 patients. Minimally invasive eTEP resulted in a rate of surgical site infection of 0% [95% CI 0.0-1.0%], a rate of seroma of 5% [95% CI 2.0-8.0%] and a rate of major complications (Clavien-Dindo III-IV) of 1% [95% CI 0.0-3.0%]. The rate of intraoperative complications was 2% [95% CI 0.0-4.0%] with a conversion rate of 1.0% [95% CI 0.0-3.0%]. Mean hospital length of stay was 1.77 days [95% CI 1.21-2.24]. After a median follow-up of 6.6 months (1-24), the rate of recurrence was 1% [95% CI 0.0-1.0%]. CONCLUSION: Minimally invasive eTEP is a safe and effective approach for ventral hernia repair, with low reported intraoperative complications and good outcomes.

RESUMO

PURPOSE: To determine the long-term outcomes of locally advanced rectal cancer (LARC) treated with neoadjuvant chemoradiation (CRT) and surgery, and to analyze the management and survival once distant failure has developed. METHODS: Data from LARC patients treated from 2000 to 2010 were retrospectively reviewed. CRT protocols were based on fluoropirimidines ± oxaliplatin. Follow-up consisted of physical examination, carcinoembryonic antigen levels, and chest-abdominal-pelvic CT scan. RESULTS: The study included 228 patients with a mean age of 59 years. Forty-eight (21.1 %) patients had distant recurrence and 6 patients (2.6 %) had local recurrence. Median follow-up was 49 months. The 5- and 10-year actuarial disease free survival was 75.3 and 65.0 %, respectively. The 5- and 10-year actuarial overall survival (OS) was 89.6 and 71.2 %, respectively. Patients were classified as having liver (14 patients) or lung (27 patients) relapse according to the organ firstly metastasized. The variables significantly associated by univariate Cox analysis to survival were the achievement of an R0 metastases resection and the Köhne risk index, while the metastatic site showed a statistical trend. By multivariate Cox analysis, the only variable associated with survival was a R0 resection (HR = 16.3, p\0.001). Median OS for patients undergoing a R0 resection was 73 months (95 % CI 67.8-78.2) compared to 25 months (95 % CI 5.47-44.5) in those non-operated patients (p\0.001). CONCLUSIONS: Combined treatment for LARC obtains a 5-year OS rounding 90 %. Follow-up based on thoracic abdominal CT scan allows an early diagnosis of metastatic lesions. Surgical resection of metastases, regardless of their location, greatly increases the patient's survival rate

RESUMO

BACKGROUND: The role of liver biopsy in the evaluation of a candidate for living liver donation is controversial. Some authors suggest doing it routinely, but others do it only in selected cases. The aim of this work was to evaluate the usefulness of protocol liver biopsy in the evaluation of candidates for living liver donation. METHODS: Ninety potential candidates for living liver donation were evaluated. In 46 cases donation was contraindicated without the need of liver biopsy. In the remaining 44 candidates, liver biopsy was done on a protocol basis. The usefulness of protocol biopsy was compared with the use of biopsy according to the recommendations of the Vancouver Forum. RESULTS: Fifteen of the 44 biopsies were indicated according to the recommendations of the Vancouver Forum. Twelve of them were normal, and 3 had liver steatosis or steatohepatitis. Of the 29 biopsies done per protocol, 28 were normal and 1 showed liver steatosis. Donation was contraindicated according to liver biopsy findings in 3 of the 15 patients with liver biopsy done according to the Vancouver Forum recommendations and in none of the 29 patients with biopsy done per protocol (P = .034). CONCLUSIONS: Protocol liver biopsy has a limited utility in the evaluation of the candidates for living liver donation.

RESUMO

A retrospective cohort multicenter study was conducted to analyze the risk factors for tumor recurrence after liver transplantation (LT) in cirrhotic patients found to have an intrahepatic cholangiocarcinoma (iCCA) on pathology examination. We also aimed to ascertain whether there existed a subgroup of patients with single tumors ≤2 cm ("very early") in which results after LT can be acceptable. Twenty-nine patients comprised the study group, eight of whom had a "very early" iCCA (four of them incidentals). The risk of tumor recurrence was significantly associated with larger tumor size as well as larger tumor volume, microscopic vascular invasion and poor degree of differentiation. None of the patients in the "very early" iCCA subgroup presented tumor recurrence compared to 36.4% of those with single tumors >2 cm or multinodular tumors, p = 0.02. The 1-, 3- and 5-year actuarial survival of those in the "very early" iCCA subgroup was 100%, 73% and 73%, respectively. The present is the first multicenter attempt to ascertain the risk factors for tumor recurrence in cirrhotic patients found to have an iCCA on pathology examination. Cirrhotic patients with iCCA ≤2 cm achieved excellent 5-year survival, and validation of these findings by other groups may change the current exclusion of such patients from transplant programs.

RESUMO

OBJECTIVE: To evaluate the outcome of patients with hepatocellular-cholangiocarcinoma (HCC-CC) or intrahepatic cholangiocarcinoma (I-CC) on pathological examination after liver transplantation for HCC. BACKGROUND: Information on the outcome of cirrhotic patients undergoing a transplant for HCC and with a diagnosis of HCC-CC or I-CC by pathological study is limited. METHODS: Multicenter, retrospective, matched cohort 1:2 study. STUDY GROUP: 42 patients undergoing a transplant for HCC and with a diagnosis of HCC-CC or I-CC by pathological study; and control group: 84 patients with a diagnosis of HCC. I-CC subgroup: 27 patients compared with 54 controls; HCC-CC subgroup: 15 patients compared with 30 controls. Patients were also divided according to the preoperative tumor size and number: uninodular tumors 2 cm or smaller and multinodular or uninodular tumors 2 cm or larger. Median follow-up: 51 (range, 3-142) months. RESULTS: The 1-, 3-, and 5-year actuarial survival rate differed between the study and control groups (83%, 70%, and 60% vs 99%, 94%, and 89%, respectively; P < 0.001). Differences were found in 1-, 3-, and 5-year actuarial survival rates between the I-CC subgroup and their controls (78%, 66%, and 51% vs 100%, 98%, and 93%; P < 0.001), but no differences were observed between the HCC-CC subgroup and their controls (93%, 78%, and 78% vs 97%, 86%, and 86%; P = 0.9). Patients with uninodular tumors 2 cm or smaller in the study and control groups had similar 1-, 3-, and 5-year survival rate (92%, 83%, 62% vs 100%, 80%, 80%; P = 0.4). In contrast, patients in the study group with multinodular or uninodular tumors larger than 2 cm had worse 1-, 3-, and 5-year survival rates than their controls (80%, 66%, and 61% vs 99%, 96%, and 90%; P < 0.001). CONCLUSIONS: Patients with HCC-CC have similar survival to patients undergoing a transplant for HCC. Preoperative diagnosis of HCC-CC should not prompt the exclusion of these patients from transplant option.

RESUMO

INTRODUCTION: Complete portal vein thrombosis (PVT) may complicate orthotopic liver transplantation (OLT), increasing its technical difficulty and the transfusion requirements and as well as affecting survival in some cases. Transjugular intrahepatic portosystemic shunt (TIPS) prevents total portal vein occlusion in patients with partial PVT. OBJECTIVE: We aimed to assess the efficacy and safety of TIPS to prevent total portal vein occlusion among patients listed for OLT. PATIENTS AND METHODS: We analyzed the clinical records of 15 consecutive patients with partial PVT who underwent TIPS before OLT. The control group consisted of 8 transplanted patients without TIPS but partial PVT diagnosed before OLT. Portal vein patency at surgery, ischemia time, and transfusion requirements during OLT, and survival thereafter were compared between both groups. The main complications were also compared: mortality after TIPS (from TIPS placement to OLT), intraoperative technical complications, and technical complications during the 6 months after OLT. RESULTS: Clinical characteristics at the time of OLT were similar between the groups. No relevant complications were observed after TIPS; all patients underwent transplantation. One- and 5-year actuarial survival rates were similar in both groups (92% and 85% in TIPS-group versus 100 and 75% in the control group, respectively). No differences in transfusion requirement, duration of ischemia, and frequency of technical complications during and after OLT were observed between the groups. The portal vein was patent at surgery in all TIPS patients and 4 of 8 (50%) in the control group (P = .008). CONCLUSION: TIPS may prevent PVT in liver transplantation candidates with partial PVT.

RESUMO

The use of the laparoscopic approach in managing early liver transplant complications has been shown to be safe and feasible in various settings with the advantages of shorter recovery period, decreased postoperative pain, and rapid functional recovery. The laparoscopic approach has been used to resolve postoperative complications in kidney and pancreas recipients and less often in orthotopic liver transplantation (OLT) recipients, most of them in the late period (> 1 month posttransplantation). We herein describe our experience with the laparoscopic management of early complications after liver transplantation. From May 2009 to May 2011, we successfully treated three patients with early abdominal complications after OLT using a laparoscopic approach. Three patients-two with intraabdominal bleedings and one with a small bowel obstruction were treated successfully, thereby avoiding risks of a relaparotomy. In addition to these benefits, the laparoscopic approach causes less tissue injury and consequently evokes a minor innate immune response.

RESUMO

BACKGROUND: Occasionally, patients with hepatocellular carcinoma (HCC) who receive radioembolization with palliative intent are downstaged for radical treatments. The aim of this study was to describe and analyze the overall survival (OS) in these patients compared with patients of the same baseline stage (UNOS T3), who were not eligible for radical treatment after radioembolization. METHODS: Between September 2003 and August 2010, 118 patients with HCC received radioembolization with yttrium-90 ((90)Y) resin microspheres. Of these, 21 patients with UNOS T3 stage were retrospectively identified and included in this analysis. RESULTS: In total, 6 of 21 patients were downstaged and treated radically between 2 and 35 months post-radioembolization. Three patients were resected, 2 received liver transplantation and 1 was ablated and then resected. Patients treated radically were significantly younger (62 vs. 73 years, p = 0.006) and had higher tumor volume (583 mL vs. 137 mL, p = 0.001) than patients who did not achieve radical treatment. There were no differences between the groups in number of lesions, BCLC stage, previous cirrhosis, activity administered per tumor volume, or median levels of alpha-fetoprotein or total bilirubin. Across the whole series, the median OS was 27.0 months (95% CI 5.0-48.9), varying significantly between those treated radically (OS not reached after a median follow-up of 41.5 months since radical therapy) and those who received palliative treatment only (22.0 months; 95% CI 15.0-30.9). CONCLUSIONS: Radical therapy following tumor downstaging with radioembolization provides the possibility of long-term survival in a select subgroup (UNOS T3 stage) with otherwise limited options.

RESUMO

INTRODUCTION: The aim of this study was to investigate the applicability of living donor liver transplantation in a program of adult liver transplantation. PATIENTS AND METHODS: We studied the outcomes of the evaluation of 71 potential donor candidates for 53 adult candidates to liver transplantation. RESULTS: Ten of the potential donor candidates did not complete their evaluation. Among the remaining 61 potential donors, 29 (47.5%) were considered to be suitable donors. Only 17 (24% of the 71 initial candidates) underwent donation. The main causes for unsuitability for liver donation were a small remnant liver and vascular anatomic variants. CONCLUSION: Fewer than 25% of potential liver donors became effective donors leading us to conclude that adult living donor liver transplantation has a low applicability.

RESUMO

Diffuse thrombosis of the entire portal system (PVT) and cavernomatous transformation of the portal vein (CTPV) represents a demanding challenge in liver transplantation. We present the case of a patient with nodular regenerative hyperplasia and recurrent episodes of type B hepatic encephalopathy concomitant with PVT as well as CTPV, successfully treated with orthotopic liver transplantation. The portal inflow to the graft was carried out through the confluence of 2 thin paracholedochal varicose veins, obtaining good early graft function and recovery of the encephalopatic episodes. This alternative should be kept in mind as an option to assure hepatopetal splanchnic flow in those cases of diffuse thrombosis and cavernomatous transformation of portal vein.

RESUMO

BACKGROUND: intraductal papillary mucinous neoplasm (IPMN) shows a series of lesions which evolve from benign lesions -adenoma- to invasive carcinoma. AIM: To analyze the clinical and pathological results of 15 patients diagnosed of IPMN, and surgically treated according to the guidelines of International Consensus Conference. MATERIAL AND METHODS: A retrospective analysis of 15 patients surgically treated between March 1993 and September 2009, according to the International Consensus recommendation. Demographic, diagnostic tools, surgical report, pathologic database and actuarial survival were analyzed with a follow-up from one and a half month through nine years. RESULTS: 6 Patients underwent pancreaticoduodenectomies, 4 total pancreatectomies, 2 body or central pancreatectomies, 2 partial pancreatectomies (enucleation) and 1 distal pancreatectomy. A morbidity of 46 and 0% hospital mortality were assessed, with a median length hospital stay of 10 days. In five cases, the IPMN was combined type (both main and branch pancreatic ducts involved) in four main duct-type and branch duct-type in the another six as well. Several atypia (IPMN carcinoma in situ) was observed in 2 patients and invasive carcinoma with negative lymph nodes was identified in 3 patients. A patient without invasive carcinoma died at 66 months of follow-up for pancreas adenocarcinoma. The actuarial survival up to recurrence or death was 105,133 months with a range of follow-up from 1 month and a half until 9 years. CONCLUSIONS: IPMN main duct or mixed type warrants complete resection due to its incidence of invasive carcinoma or precursor lesions of malignancy as well. Due to its multifocal pattern, patients should be followed in long-term surveillance. The management of asymptomatic IPMN type branch less than 3 cm is controversial.

Se registróuna morbilidad del 40%, sin mortalidad operatoria, con unaestancia media de 10 días. En 5 casos la NPMI fue de tipo mixto,en 4 afectaba al conducto pancreático y en los 6 restantes a ramasaccesorias. Dos pacientes presentaron carcinoma in situ y 3carcinoma invasivo con ganglios negativos. Un paciente, sin carcinomainvasivo, falleció a los 66 meses por adenocarcinoma depáncreas. La supervivencia actuarial hasta recidiva o muerte fuede 105,133 meses; con un rango de seguimiento entre mes y medioy 9 años.Conclusiones: la NPMI tipo ductal y mixto exige la reseccióncompleta debido a la elevada incidencia de carcinoma invasivo ode lesiones precursoras de malignidad. Por su carácter multifocallos enfermos deben ser revisados a largo plazo. Existen controversiasen las NPMI tipo accesorio asintomáticas y menores de 3 cm(AU)

RESUMO

RESUMO

Introducción: El carcinoma tubular de mama (CTM) representaun subtipo de carcinoma infiltrante, bien diferenciado,poco frecuente, de diagnóstico diferencial en ocasiones difícil.Material y métodos: Estudio retrospectivo de 38 casos queanaliza algunas de sus características clínicas y biológicas, asícomo del tratamiento utilizado.Resultados: Edad media de 51,5 años, el motivo diagnósticomás común fue la presencia de una tumoración palpable(50%), y otro 50% resultado de un chequeo mamario. En trescasos se presentó un carcinoma bilateral (uno de ellos sincrónico).Tamaño tumoral medio de 1,4 cm; el 81,8% fueron pT1.Afectación ganglionar axilar en el 13,1% de los casos (todosCTM mixtos). Se observó alto índice de tumores RE positivos,bajo índice proliferativo (Ki67) y muy baja expresión de p53 yc-erbB2. En el 79% de los casos se practicó cirugía conservadoracon vaciamiento axilar. La supervivencia a 10 años fuedel 97,4%.Conclusiones: Carcinoma poco frecuente, cuyo hallazgoes cada vez más resultado de estudios de screening. Se presentacomo una imagen estelar que obliga al diagnóstico diferencialcon algunas lesiones benignas.Su habitual pequeño tamaño y buena diferenciación histológica,permiten el tratamiento conservador en la mayoría delos casos, siendo excepcional la afectación ganglionar axilar.Dado su buen pronóstico, se discute la utilidad/necesidadde tratamiento adyuvante e incluso la cirugía axilar en los detamaño < 1 cm, especialmente en las formas puras(AU)


Introduction: Tubular carcinoma (TC) is a rare and well-differentiatedhistological variant of all breast cancer. The diagnosisof TC is some occasions difficult.Material and methods: We conducted a retrospectivestudy that analyzes 38 cases of TC (it supposes 1,6% of BreastCancer treated in our Breast Unit).The clinical and biological features and the treatment areanalyzed.Results: The medium average age was of 51,5 years. Themore frequent consultation was the presence of a palpablebreast mass followed by the screening. In three patients weobserved a bilateral cancer (1 out of 3 were synchronous tumour).The size half size tumour was of 1,4 cm and 81,8% theywere tumours pT1. Metastatic axillary disease was observed in13,1% of cases. We found a high rate of tumours was with positivehormonal receivers, low KI-67) and very low expressionof p53 and c-erb-2. The 79% of patient were treated with breastconservation therapy. With a median follow-up of 10 yearsthe survival was 97,4%.Discusion: TC is a rare breast cancer that can be discoveredin screening. TC can appear in mammography as a spiculatedabnormality and therefore it can be difficult to distinguishfrom radial scar or sclerosing adenosis. TC usually presents asa small tumour that can be treated with conservative surgery.Maxillary nodal metastases are uncommon. Because it is goodprognosis, adjuvant postoperative treatment and even any axillarysurgical procedure are controversial in TC(AU)
