Análise de colecistectomias videolaparoscópicas no Hospital de Clínicas de Porto Alegre

OBJECTIVE: Laparoscopic cholecystectomy (LC) is the treatment of choice for cholelithiasis. Our objective was to assess the results of LC in comparison with previous data published in 1994.PATIENTS AND METHODS: From 1992 to 1999, 2,300 patients were submitted to surgery at the Hospital de Clínicas de Porto Alegre. The medical records of 1,540 of these patients were assessed retrospectively. The variables evaluated were preoperative diagnosis, duration of hospital stay and of surgery, intra- and postoperative complications, conversion rate to open surgery, and anatomicopathological examination of the gallbladder.RESULTS: The most common preoperative diagnosis was of symptomatic gallstones (92%); the average hospital stay was of 3.6 ± 6 days (median of 2 days); the average duration of surgery was of 89.5 ± 38 minutes; the most frequent intraoperative complications were gallbladder rupture (7.3%), calculi in peritoneum (0.8%), and iatrogenic bile duct injury (0.2%); and the postoperative complications reported were wound infection (1.3%), retained stones (0.6%), and biliary peritonitis (0.5%). The conversion rate to open procedure was of 2.5%, and reoperation was necessary in 1.8% of cases. There was only one death (0.06%).CONCLUSION: In comparison to data from a previous experience, there has been an improvement in LC results, but additional technical improvements can still be made. OBJETIVO: A colecistectomia videolaparoscópica (CVL) é o tratamento preferencial da colelitíase. O objetivo deste trabalho é avaliar os resultados da CVL comparando com a experiência inicial relatada em 1994.PACIENTES E MÉTODOS: De 1992 a 1999 foram operados 2.300 pacientes no Hospital de Clínicas de Porto Alegre. Deste total foram revisados retrospectivamente 1.540 prontuários. As variáveis analisadas foram a indicação cirúrgica, o tempo de internação hospitalar e cirúrgico, as complicações trans e pós-operatórias, a taxa de conversão para cirurgia aberta e o exame anatomopatológico da vesícula biliar.RESULTADOS: A principal indicação de cirurgia foi a colelitíase sintomática (92%). O tempo de internação hospitalar foi 3,6 ± 6 dias e a mediana de 2 dias e o tempo cirúrgico médio de 89,5 ± 38 minutos. As principais complicações intra-operatórias foram a perfuração da vesícula biliar (7,3%), a queda de cálculos na cavidade (0,8%) e lesão iatrogênica de via biliar (0,2%). No pós-operatório, as complicações mais freqüentes foram a infecção de ferida operatória (1,3%), a coledocolitíase residual (0,6%) e o coleperitônio (0,5%). A taxa de conversão foi de 2,5% e de reoperação de 1,8%. Houve apenas um óbito (0,06%).CONCLUSÕES: Em relação à experiência inicial, a CVL evoluiu muito, mas ainda pode ser aprimorada tecnicamente. &nbsp

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
