[Boerhaave's syndrome: a review of our experience over the last 16 years]. / Síndrome de Boerhaave: revisión de nuestra experiencia en los últimos 16 años.

OBJECTIVE: Report our experience in the diagnosis and treatment of Boerhaave syndrome by retrospective study from 1997 to 2013. PATIENTS AND METHODS: A retrospective study was conducted covering the time frame of 1997 to 2013. RESULTS: There were a total of 5 men (71%) and 2 women (29%) and the mean age was 54 years (range: 33-80 years). Diagnosis was made through computed tomography scan in 5 cases (71%) and esophagogram in 2 cases (19%). Six patients (86%) had emergency surgery, whereas one case (14%) was managed conservatively. The surgical technique employed was primary suture and repair in 4 patients (67%) and esophageal resection and subsequent cervical esophagostomy in 2 patients (33%). CONCLUSIONS: Boerhaave's syndrome is a clinically rare entity with an elevated mortality rate. Therefore, a high degree of suspicion is necessary for making the diagnosis and providing early treatment that can result in improved outcome.

[Laparoscopic apendicectomy vs open approach for the treatment of acute appendicitis]. / Apendicectomía laparoscópica frente al abordaje abierto para el tratamiento de la apendicitis aguda.

BACKGROUND: There is no international consensus on the approach of choice for performing appendectomy. AIMS: To analyze and compare open and laparoscopic approaches in the surgical treatment of acute appendicitis. MATERIAL AND METHODS: A retrospective study was carried out on patients over 14-years-old operated on for suspected acute appendicitis between January 2007 and December 2009. Variables were: age, sex, body mass index, specialized surgeon or resident in training, progression duration, conversion rate, use of drains, abdominal cavity irrigation, macroscopic appearance of the appendix, onset time of anesthesia, ASA classification, postoperative hospital stay, resumption of intake of liquids, and complications. The patients were divided into two groups: laparoscopic approach (LA) and open approach (OA). RESULTS: A total of 533 patients were enrolled (290 LA and 243 OA). Onset time of anesthesia was 75 min (30-190 min) in LA vs 55 min (20-160 min) in OA (p<0,0001). COMPLICATIONS: intraabdominal abscesses in 17 LA cases vs 13 OA cases (p=0,79); surgical wound alterations in 16 LA cases vs 47 OA cases (p=0,0001); incisional hernias in 2 LA cases (1%) vs 10 OA cases (p=0,008). There were no statistically significant differences in postoperative hospital stay (3 days), resumption of intake of liquids (1 day) or readmission rate (8%). CONCLUSIONS: There are fewer surgical wound alterations and incisional hernias with the laparoscopic approach, but there is higher cost, lengthier surgery duration, and a longer learning curve. Our results cannot provide a clear indication for one approach or the other, and therefore each case must be evaluated on an individual basis.

Impact of the total number of harvested lymph nodes after colon cancer resections on survival in patients without involved lymph node.

BACKGROUND: The total number of harvested lymph nodes has been demonstrated to be of prognostic significance for colon cancer. Differences can occur in the total number of harvested lymph nodes between different specialists (surgeons and pathologists). OBJECTIVE: The aim of this study was to analyse if, in our centre, the number of analysed lymph nodes in patients with colon cancer that are classified as pN0 is also related to survival. MATERIAL AND METHODS: A retrospective study was designed, where 148 patients with colon adenocarcinoma (pN0 of TNM classification) who underwent elective surgery between 1 January 1995 and 31 December 2001, with curative intent were included. Three groups were created according to the number of analysed lymph nodes ( < 7, 7-14, > 14 lymph nodes). For survival analysis the Kaplan-Meier and CUSUM curves methods were used. RESULTS: The total number of analysed lymph nodes was 1,493 (mean 10.1 lymph nodes per patient). The rate of 5-years survival was 63.0% in the group with < 7 lymph nodes; 7-14 lymph nodes: 80.6% and those with > 14 lymph nodes: 91.8% (p < 0.01). Prognostic significance was also present for multivariate analysis. CONCLUSION: In our centre, harvesting a larger number of lymph nodes is related to improved rates of 5-years survival for patients with colon cancer staged as pN0. It seems reasonable to recommend obtaining as many lymph nodes as possible, and not to establish a minimum number of lymph nodes to be harvested.

Gallstone ileus: management options and results on a series of 40 patients.

INTRODUCTION: Controversy remains about the management of gallstone ileus. While some authors propose enterotomy, others defend the one-stage procedure (simultaneously fistula repair). The objective of the present study was to analyze management options and comparative study their results. MATERIAL AND METHODS: Retrospective and descriptive study with revision of clinical stories of patients with the diagnosis of gallstone ileus between 1987 and 2008. All the following variables were recorded: dates of hospital admission, surgery and discharge, age, sex, pathological antecedents, preoperative or intraoperative diagnosis, treatment, location of the fistula and location of the obstruction. End-result variables were: postoperative complications, mortality, complications during the follow-up and biliary complications. RESULTS: A total of 40 patients were included of 46,648 admissions. Age, comorbidity, and intraoperative diagnosis were related with poorer short- and long-outcomes. The percentage of postoperative complications was similar for groups with and without fistula repair. Mortality was higher in the group with fistula repair (15 vs. 25%). Biliary complications were more frequent in the group without fistula repair (11 vs. 0%). Sex, location of the fistula and location of the obstruction did not be related with the prognosis. CONCLUSION: One-stage procedure is related with higher mortality rate than enterotomy alone. Nevertheless, fistula repair reduces the number of biliary complications during the follow-up.

Íleo biliar: opciones terapéuticas y resultados en una serie de 40 casos / Gallstone ileus: management options and results on a series of 40 patients

Introducción: todavía existe gran controversia sobre el mejor tratamiento del íleo biliar. Algunos autores proponen la enterotomía aislada, mientras otros defienden la reparación de la fístula bilioentérica en el mismo acto quirúrgico. El objetivo del presente estudio fue analizar las opciones terapéuticas en estos pacientes y estudiar sus resultados. Material y métodos: estudio retrospectivo y descriptivo, con revisión de las historias clínicas de los pacientes diagnosticados de íleo biliar desde 1987 hasta 2008. Se recogieron las fechas de ingreso, de intervención y del alta, edad, sexo, antecedentes patológicos, diagnóstico preoperatorio o intraoperatorio, tratamiento, lugar de la fístula y lugar de la obstrucción. Como variables de resultado se utilizaron las complicaciones postoperatorias, mortalidad, complicaciones en el seguimiento y complicaciones biliares. Resultados: se incluyeron 40 pacientes sobre 46.648 ingresos. La edad, la comorbilidad y el diagnóstico intraoperatorio se relacionaron con peores resultados a corto y largo plazo. El porcentaje de complicaciones postoperatorias fue similar para el grupo con abordaje de la fístula y para el grupo con enterotomía aislada. La mortalidad fue superior en el grupo con abordaje de la fístula (15 frente a 25%). Las complicaciones biliares fueron más frecuentes en el grupo sin abordaje de la fístula biliar (11 frente a 0%). El sexo, lugar de la fístula o el lugar de la obstrucción no demostraron diferencias. Conclusión: la cirugía en un solo tiempo se relaciona con mayor mortalidad que la enterotomía aislada. No obstante, añadir la reparación de la fístula reduce el número de complicaciones biliares en el seguimiento(AU)
