A diatom data-base of 255 species obtained from 14 oceanographic cruises (14801 entries of 647 sampling sites) together with the analysis of oceanic features were used to establish four local regions in the southern Gulf of Mexico. In addition, common species for each region were designated. This study is based on the application of cluster analysis and the species frequency data. Material for this undertaking consisted of water and net samples obtained between June 1979 and December 2002. Results show that the most frequent species (> 40%) were: Asterionellopsis glacialis, Bacteriastrum delicatulum, B. hyalinum, Chaetoceros affinis, C. coarctatus, C. compresus, C. curvisetus, C. danicus, C. decipiens, C. diversus, C. lorenzianus, C. pelagicus, C. peruvianus, Coscinodiscus radiatus, Cylindrotheca closterium, Guinardia flaccida, Hemiaulus hauckii, H. membranaceus, H. sinensis, Leptocylindrus danicus, Neocalyptrella robusta, Nitzschia bicapitata, Pleurosigma diverse-striatum, Proboscia alata, Pseudo-nitzschia pungens, Pseudosolenia calcar-avis, Rhizosolenia imbricata, R. setigera, Skeletonema costatum, Thalassionema bacillare, T frauenfeldii, T nitzschioides and Thalassiosira eccentrica. The species composition for each region and season are discussed. Itis concluded that sampling site assemblages are related to oceanographic conditions. A total list of species composition is given, forty-seven species taxa being new records for this area.

INTRODUCTION: We assessed the results of laparoscopic cholecystectomy in 176 patients over the age of 70 years. PATIENTS AND METHODS: The study included all patients older than 70 years of age who underwent laparoscopic surgery cholelithiasis during the previous ten years. Variables studied included age, sex, type of operation (programmed/emergency), comorbidity, anesthetic risk, intraoperative cholangiography, conversion to open surgery, number of trocars, reoperation, residual choledocholithiasis, postoperative hospital stay, morbidity and mortality. RESULTS: The study included 176 patients (23.29% men and 76.71% women). The mean age was 74.86 years. The mean hospital stay was 1.27 days, with 16.98% morbidity and 0.56% mortality. CONCLUSIONS: Laparoscopic cholecystectomy is a safe procedure in older patients. It results in faster recovery, a shorter postoperative stay and lower rates of morbidity and mortality than open bile duct surgery.

Objetivo: el objetivo de nuestro estudio es el de evaluar los resultadosobtenidos en 176 pacientes mayores de 70 años intervenidosmediante colecistectomía laparoscópica.Pacientes y métodos: se incluyen en el estudio todos los pacientesmayores de 70 años diagnosticados de colelitiasis intervenidospor laparoscopia en los diez últimos años. Analizamos los siguientesparámetros: edad, sexo, tipo de intervención(programada/urgente), comorbilidad, riesgo anestésico, colangiografíaintraoperatoria, conversión a cirugía abierta, número detrócares, reintervención, coledocolitiasis residual, estancia hospitalariapostoperatoria y morbimortalidad.Resultados: incluimos en el estudio un total de 176 pacientes,de los cuales el 23,29% son varones y 76,71%, tienen unaedad media de 74.86 años. En los resultados globales la estanciamedia hospitalaria es de 1,27 días, morbilidad 16,98% y mortalidadde 0,57%.Conclusiones: la colecistectomía laparoscópica es un procedimientoseguro en pacientes mayores, ofreciendo una más tempranarecuperación, menor estancia postoperatoria, y una menortasa de morbimortalidad que la cirugía biliar abierta
