RESUMO
BACKGROUND: The concept of natural orifice transluminal endoscopic surgery (NOTES) has stimulated the development of various "incisionless" procedures. One of the most popular is the transanal approach for rectal lesions. The aims of this study were to report how we standardized NOTES technique for transanal mesorectal excision without abdominal assistance, discuss the difficulties and surgical outcomes of this technique and report its feasibility in a small group of selected patients. METHODS: Three consecutive female patients underwent transanal NOTES rectal resection without transabdominal laparoscopic assistance for rectal lesions. Functional results were assessed with the Fecal Incontinence Quality of Life scale and the Wexner score. RESULTS: The technical steps are described in details and complemented with a video. All procedures were completed without transabdominal laparoscopic help. The mesorectal plane was entirely dissected without any disruption, and distal and circumferential margins were tumor-free. No major complications were observed. Functional results show a significant impairment after surgery with improvement at 6 months to levels near those of the preoperative period. CONCLUSIONS: The performance and publication of NOTES procedures are subject to much discussion. Despite the small number of patients, this procedure appears feasible and can be accomplished maintaining fecal continence and respecting oncologic principles.

BACKGROUND: Abdominoperineal resection (APR) is not free of complications, in particular complications due to the occupation of the pelvis by the small bowel after surgery. A number of surgical techniques have been described to prevent the small bowel from entering and adhering to the pelvis (pelvic partition), but there is no agreement concerning their use. The aim of this study was to evaluate the feasibility, effectiveness and safety of using an absorbable synthetic prosthetic material for pelvic partitioning after APR. METHODS: A prospective non-randomised longitudinal pilot study was carried out on a series of 10 patients who underwent APR due to lower-third rectal cancer, in order to evaluate the feasibility, safety and efficacy of pelvic partitioning with an absorbable synthetic prosthetic material. RESULTS: In all the patients, it was possible to perform a radical resection and to install the prosthesis. After a mean follow-up of 9 months (range: 4-18 months), no abdominal or perineal complications were detected. One patient (10%) suffered chronic pelvic pain. CONCLUSIONS: Pelvic partition after APR of the rectum with an absorbable synthetic prosthesis is feasible, effective and safe.

INTRODUCTION: Neuromuscular blockade enables airway management, ventilation and surgical procedures. However there is no national consensus on its routine clinical use. The objective was to establish the degree of agreement among anaesthesiologists and general surgeons on the clinical use of neuromuscular blockade in order to make recommendations to improve its use during surgical procedures. METHODS: Multidisciplinary consensus study in Spain. Anaesthesiologists experts in neuromuscular blockade management (n=65) and general surgeons (n=36) were included. Delphi methodology was selected. A survey with 17 final questions developed by a dedicated scientific committee was designed. The experts answered the successive questions in two waves. The survey included questions on: type of surgery, type of patient, benefits/harm during and after surgery, impact of objective neuromuscular monitoring and use of reversal drugs, viability of a multidisciplinary and efficient approach to the whole surgical procedure, focussing on the level of neuromuscular blockade. RESULTS: Five recommendations were agreed: 1) deep neuromuscular blockade is very appropriate for abdominal surgery (degree of agreement 94.1%), 2) and in obese patients (76.2%); 3) deep neuromuscular blockade maintenance until end of surgery might be beneficial in terms of clinical aspects, such as as immobility or better surgical access (86.1 to 72.3%); 4) quantitative monitoring and reversal drugs availability is recommended (89.1%); finally 5) anaesthesiologists/surgeons joint protocols are recommended. CONCLUSIONS: Collaboration among anaesthesiologists and surgeons has enabled some general recommendations to be established on deep neuromuscular blockade use during abdominal surgery.

BACKGROUND: The increasing number of recipients on the waiting list for orthotopic liver transplantation (OLT) and the scarcity of donors contribute to recipient pretransplantation mortality. One important measure to increase the donor liver pool would be to accept the previously discarded donors who are more than 80 years old. METHODS: From November 1996 to May 1998, four liver grafts from octogenarian donors (89, 87, 82, and 85 years old, respectively) were used for OLT. Pretransplantation donor and recipient characteristics and the evolution of recipients after OLT were analyzed. RESULTS: The donors did not present cardiac arrest or hypotension, and only low doses of vasopressors were required in three of them. Intensive care unit stay of the donors was from 12 to 24 hr. Cold ischemia time was from 4 hr to 8 hr 40 min. Mild microsteatosis was present in three donors and associated macrosteatosis of < 10% in one of these. Macroscopic appearance and consistency were normal in all four grafts. Posttransplantation evolution and follow-up were uneventful. Three recipients were alive and well at 24, 16, and 7 months; the second of these died at 16 months of recurrent viral C cirrhosis after a first OLT. CONCLUSIONS: The liver donor pool can be increased if liver grafts are accepted without an age limit but in good condition (hemodynamic stability, short intensive care unit stay, good liver function, soft consistency, cold ischemia time <9 hr, and no severe steatosis). Octogenarian donors should be individually assessed in the absence of these ideal conditions.

Steatosis or fatty change is a common finding in donor liver biopsies during liver transplantation, and seems to be more frequent than in the general population. Fat can be stored in hepatocytes within macrovacuoles (macrosteatosis) or microvacuoles (microsteatosis), with different degrees of severity. Higher degrees of both macro and microsteatosis may increase the severity of the ischemia-reperfusion lesion producing an initial poor function in the recipient. Different pathogenic mechanisms have been investigated. However, only severe macrosteatotic (> 60%) grafts have been associated with primary non-function, and are universally rejected for transplantation. While donor livers with any severity of microsteatosis do not influence recipient survival and can be safely implanted, donor livers with moderate to severe macrosteatosis (30-60%) have a relative risk of primary non-function and should be considered for transplantation in the absence of other known risk factors. A protocol with a rational use of these steatotic livers is suggested.

In this study, we have analyzed a series of 88 patients who underwent total gastrectomy followed by two different reconstructive procedures, Roux-en-Y jejunal interposition (57%) and interposition of a jejunal limb between the oesophagus and the duodenum (38%) (Henley procedure). We examined diet, intestinal transit, symptoms of dumping syndrome and body weight curves. Patients with Roux-en-Y reconstruction presented post-prandial sweating more often (48%) than patients with the Henley procedure (21%). Forty percent patients with Roux-en-Y reconstruction suffered post-prandial nausea whereas this finding was not associated with patients after the Henley procedure. The reconstructive method has to be chosen considering the age and general condition of the patient, stage of the neoplasia and its curability. We currently favor Roux-en-Y esophagojejunostomy. However, in selected patients the Henley procedure may prove useful in order to prevent reflux and dumping symptoms.

The incidence of colorectal cancer is low in young patients. Because of the infrequent occurrence of this disease in those less than 40 years of age many of the published reports give conflicting results. The aim of this report is to study colorectal cancer in patients < or = 45 years old, a group rarely considered by other authors. We analyzed retrospectively the clinical features of our patients with special reference to the clinical data, personal and family history, site of lesion, and Duke's classification. Potential risk factors were analyzed for their effect on the survival of these patients. Finally, to evaluate the prognostic influence of potential risk factors and detect any interaction, a multivariate analysis was performed. We found 26 (17.2%) patients less than 45 years old with colorectal cancer. The clinical presentation, tumor site, and Duke's grade were similar in the young adult and in the general population but morbidity, mortality and postoperative complications were lower. There were no differences in resection or survival rates. Potential risk factors were no different from those of the general population.

OBJECTIVE: the aim of this study was to evaluate potential risk factors related to the development of primary liver graft dysfunction (PDF), including initial poor function (IPF) and primary nonfunction (PNF), and to describe a statistical predictive model for this complication. METHODS: to evaluate potential risk factors for the development of PDF (IPF and PNF), patients were classified into three groups on the basis of early postoperative graft function, and their medical charts were reviewed for donor, recipient and peroperative information. To evaluate the prognostic influence of potential risk factors, those that were statistically significant in the univariate analysis were subsequently studied by multivariate analysis using a Cox model. The study group comprised 214 liver transplants performed in 177 recipients. RESULTS: of the 214 liver transplants considered, 153 (71.5%) presented immediate graft function and 61 (28.5%) developed primary dysfunction. Initial poor function occurred in 43 (20.1%), while in 18 (8.4%) primary nonfunction of the liver was found. The severity of steatosis and preservation injury, recipient serum creatinine level, UNOS status, use of venovenous bypass, intraoperative coagulopathy and intraoperative bile output, reached statistical significance in the multivariate analysis and were predictors of PDF. CONCLUSIONS: the predictive model obtained is a useful tool to evaluate donors and recipients for liver transplantation, and for the early detection of primary dysfunction.

The Budd-Chiari syndrome or obstruction of the hepatic veins and/or suprahepatic inferior vena cava is a rare process, frequently associated with hypercoagulable states. There exist several clinical presentations, being most common the acute and subacute forms and rarely seen the fulminant and chronic forms (cirrhosis or fibrosis associated). We present here a female patient with Budd-Chiari syndrome produced by polycythemia, resolved by mesentericocaval interposition "H" shunt using internal jugular vein, after analyzing the current different modalities of medical-surgical treatment, specially portal system shunts and liver transplantation, related to presentation form.

INTRODUCTION: Pulmonary sequestration (PS) is an extremely rare malformation defined as a portion of lung tissue isolated from the pulmonary system. PSs are classified into intralobar type and intra-abdominal PS that represents only 2.5% of cases. There are 20 cases of PS reported in adults and only two were managed by laparoscopic approach. We report a case of intra-abdominal PS mimicking a gastroesophageal duplication cyst in an adult. Besides its rarity, this is the first intra-abdominal PS in an adult managed by an anterior laparoscopic approach. PRESENTATION OF CASE: A 60-year-old female patient had had epigastric and left upper quadrant pain for several days. Physical examination was normal. Image test were consistent with a gastroesophageal duplication. The patient was taken to the operating room for laparoscopic exploration and resection. The pathological diagnosis was extralobar pulmonary sequestration. DISCUSSION: Less than 20 cases of PS have been reported in adults and only two cases were managed by a lateral laparoscopic approach. In contrast to these reports, we used an anterior approach due to the GEJ suspected origin of the mass. CONCLUSION: Extralobar intra-abdominal PS is an extremely rare condition during adulthood but this diagnosis should be included in the differential diagnosis of a left-sided suprarenal mass. Due to the difficulty in achieving a definitive preoperative diagnosis, surgery is recommended. Laparoscopic resection is safe and effective but careful preoperative imaging studies are recommended in order to plan the most suitable approach.
RESUMO
BACKGROUND: To present the data of laparoscopy in liver surgery and to assess the real indications and outcomes of this kind of approach. METHODS: From February 2000 to March 2008, a prospective study was performed on 182 patients from 15 Spanish surgical centres. RESULTS: A total of 308 lesions was collected. The mean age was 57 years old, and 61.5% were female. Among patients with cystic lesions we found: 45 simple cysts, 19 policystic diseases, 12 hydatidic cysts and 2 cystoadenomas. Among solid lesions (n = 104), we found 34 patients with benign pathology (12 focal nodular hyperplasia, 10 adenomas, 7 haemangyomas and 5 other lesions) and 70 with malignant pathology (38 metastases, 29 hepatocellular carcinomas, 2 cholangiocarcinomas and 1 lymphoma). The global rate of conversion was 8.8%. The global morbidity rate was 14.8%, and 5 of them required re-intervention. CONCLUSIONS: Nowadays there are strong criteria for patients being submitted to laparoscopy procedures based both on type and location features. The postoperative morbidity rate is low, also for hepatocellular carcinoma in cirrhotic liver. In case of malignant pathology, we think the use of ultrasonography is mandatory to obtain a free margin, which implies a long-term survival rate.

Introducción. El bloqueo neuromuscular facilita la manipulación de la vía aérea, la ventilación y procedimientos quirúrgicos, pero no hay un consenso a nivel nacional que facilite la práctica clínica habitual. El objetivo fue conocer el grado de acuerdo entre anestesiólogos y cirujanos sobre el uso clínico del bloqueo neuromuscular, para establecer recomendaciones de mejora de su empleo durante un procedimiento anestésico-quirúrgico. Métodos. Estudio de consenso multidisciplinar en España, que incluyó anestesiólogos expertos en bloqueo neuromuscular (n=65) y cirujanos generales (n=36). Se utilizó metodología Delphi. Cuestionario con 17 preguntas consensuado por un comité científico, al que respondieron los expertos en dos olas. El cuestionario incluyó preguntas sobre: tipo de cirugía, tipo de paciente, beneficios/perjuicios durante y después de la cirugía, repercusión de la monitorización objetiva y del uso de fármacos reversores, la viabilidad de abordaje multidisciplinar y eficiente del procedimiento quirúrgico, enfocado en el grado de bloqueo neuromuscular. Resultados. Se establecieron cinco recomendaciones: 1) el bloqueo neuromuscular profundo es muy adecuado en cirugía abdominal (grado de acuerdo 94,1%), y 2) en pacientes con obesidad (76,2%); 3) el mantenimiento del bloqueo neuromuscular profundo hasta el final de la cirugía puede ser beneficioso en aspectos clínicos, como inmovilidad del paciente o mejor acceso quirúrgico (86,1 y 72,3%); 4) la monitorización cuantitativa y la disponibilidad de reversores del bloqueo neuromuscular es recomendable (89,1%); 5) se recomiendan protocolos de actuación conjuntos entre anestesiólogos y cirujanos. Conclusiones. La colaboración entre anestesiólogos y cirujanos generales, ha permitido establecer una serie de recomendaciones genéricas sobre el uso de bloqueo neuromuscular profundo en cirugía abdominal (AU)

INTRODUCTION: Experience in laparoscopic liver surgery is limited, and multicenter studies with large series are required for a critical evaluation of this type of surgery. OBJECTIVE: To analyze the results of the National Registry of Laparoscopic Liver Surgery. Indications, technical features, conversion rates, morbidity, and mortality were analyzed. PATIENTS AND METHOD: Seventy-four patients from 10 centers who underwent surgery between February 2000 and April 2005 were included. There were 58 women and 16 men, with a mean age of 55 years. More than one lesion was present in 16 patients. Consequently, 74 patients with 156 lesions were treated. RESULTS: Forty-six patients had cystic lesions (26 simple cysts, 13 polycystic disease, five hydatid cysts and two cystic adenomas). Surgical treatment consisted of 37 fenestrations, five cystopericystectomies, two atypical resections, one segmentectomy and one bisegmentectomy of segments II-III. In 28 patients the lesions were solid (four adenomas, six focal nodular hyperplasias, three hemangiomas, four hepatocarcinomas, five colorectal metastases, two lung metastases, one breast metastasis, one malignant melanoma metastasis, one pancreatic vipoma metastasis, and one lymphoma). Ten bisegmentectomies of segments II-III, 17 atypical resections and one segmentectomy of segment III were performed. Other surgery was associated in 23 patients. The mean operating time was 160.5 minutes and the conversion rate was 8%. The mean length of hospital stay was 5.6 days and was less than 5 days in 78% of the patients. Analgesia was administered for less than 48 hours in 55%. Morbidity was observed in eight patients (10.8%). Reoperations were performed in three patients. There was no mortality in this series. CONCLUSIONS: Laparoscopic hepatic resection is safe and feasible in selected patients. Large, controlled series are required to determine long-term outcomes. The national registry provides a good basis for evaluating laparoscopic liver surgery in Spain.

Introducción. La experiencia en cirugía hepática por laparoscopia es limitada; para realizar una valoración crítica son necesarias series amplias y multicéntricas. Objetivo. Analizar los resultados del registro nacional de cirugía hepática por vía laparoscópica. Valorar las indicaciones, los aspectos técnicos, el índice de conversión y la morbimortalidad. Pacientes y método. Se incluye a 74 pacientes de 10 centros de febrero de 2000 a abril de 2005. Cincuenta y ocho mujeres y 16 varones, con una edad media de 55 años. Dieciséis pacientes presentaban más de una lesión, por lo que se trató a 74 pacientes con 156 lesiones. Resultados. Cuarenta y seis pacientes presentaban lesiones quísticas (26 quistes simples, 13 enfermedad poliquística, 5 quistes hidatídicos y 2 cistoadenomas). Se practicaron 37 fenestraciones, 5 quistoperiquistectomías, 2 resecciones limitadas, 1 segmentectomía y 1 bisegmentectomía II-III. En 28 pacientes las lesiones eran sólidas (4 adenomas, 6 hiperplasias nodulares focales, 3 hemangiomas, 4 hepatocarcinomas, 5 metástasis colorrectales, 2 metástasis de pulmón, 1 metástasis de mama, 1 metástasis de melanoma maligno, 1 metástasis de vipoma pancreático y 1 linfoma). Se realizaron 10 bisegmentectomias II-III, 17 resecciones limitadas y 1 segmentectomía del segmento III. En 23 casos se asoció otra cirugía. El tiempo quirúrgico medio fue de 160,5 min y el índice de conversión, del 8%. La estancia media fue de 5,6 días, y el 78% de los pacientes estuvo menos de 5 días. En el 55% la analgesia se administró menos de 48 h. La morbilidad fue de 8 casos (11%). Tres casos fueron reintervenidos. No existió mortalidad en la serie. Conclusiones. La resección hepática laparoscópica es factible y segura en casos seleccionados. Se hace necesario disponer de series amplias y controladas para conocer los resultados a largo plazo. El registro nacional es una buena alternativa para valorar la cirugía hepática realizada por vía laparoscópica en España (AU)

Los colangiocarcinomas hiliares son neoplasias poco frecuentes que, por su localización anatómica, plantean importantes dificultades técnicas en la resección quirúrgica. La supervivencia a largo plazo sólo se consigue en los casos resecados, por lo que es importante la identificación de los pacientes que presentan factores de riesgo, así como el diagnóstico precoz y la valoración de la resecabilidad por un cirujano experimentado en cirugía hepatobiliar. En este trabajo se pretende dar una visión de conjunto del colangiocarcinoma hiliar, que abarca los factores de riesgo, el diagnóstico (las pruebas de laboratorio, las técnicas de diagnóstico por imagen, la anatomía patológica) y las distintas modalidades de tratamiento, especialmente la resección quirúrgica. Se comparan las tasas de resecabilidad y la supervivencia a largo plazo tras la resección con intención curativa en las series más relevantes de la bibliografía. Asimismo, se exponen las modalidades de tratamiento paliativo quirúrgico y radiológico en los casos irresecables y las terapias adyuvantes utilizadas por los diferentes autores (AU)
