Divertículo do apêndice vermiforme

The authors present three cases report of appendicular diverticulum with associated diverticulitis, one of them asymptomatic. The clinical distinction between acute apendicitis and apendical diverticulitis is very difficult, the later usually with earlier suppuration. The are no consensus regarding preventive surgery for apendical diverticulitis. It is possible that incidence of apendicular diverticulum depends on careful anatomopathological exams.

Carcinoma epidermóide "in situ" em divertículo de Zenker

The epidermoid carcinoma "in situ" in a Zenker's diverticulum is a rare disease. The goal of this work is to report one case of epidermoid carcinoma "in situ" in a Zenker's diverticulum of long lasting symptomatology, treated by conservative surgery. In ambulatorial attendance, this patient showed a good evolution and favorable prognosis.

Divertículo de Zenker: relato de três casos

Pharyngoesophageal diverticula are epithelial-lined pouches that protrude from the esophageal lumen. They were studied by Zenker in 1878,receiving the denomination of Zenker's diverticulum. They are false diverticula since they don't have all layers of the esophageal wall. Although they are most common esophageal diverticula . Their incidence is of 3% of the patient presenting dysphagia. Current , there are several therapeutic modalities, from dilatation of the esophagus to surgery with resection of the diverticulum. The report refers to three patients with Zenker's diverticulum who underwent conventional surgical treatment.

Hérnia de Littré causando obstrução intestinal

The authors describe a case of a 60-year-old male with a history of a mass and pain at the right inguinal and epigastric areas. He also reported symptoms of bowel obstruction. Physical examination revealed a mass at right inguinal area, which was not reducible or pulsatile. Surgical findings included hernial sac contents with loop of ileum with signs of ischemia and a Meckel's diverticulum. Histopathological examination showed herniation of the Meckel diverticulum -Littré hernia. The article discusses the history and the incidence of this rare form of hernia.

Perfuração de intestino delgado por doença diverticular jejunal

Small Intestine's diverticulosis is an uncommon pathology of intestine. It's more evident at jejune and can be complicated by intestinal perforation, obstruction or diverticulitis, increasing the mortality. We describe a forty years old female patient that arrived at emergency service complained of diffuse abdominal pain. There aren't signals of peritonitis and the radiological evaluation showed small intestine's distension. Surgical intervention was performed revealing multiples diverticulums at jejune and intestinal perforation. The aim of this article is present a case of Small Intestine's diverticulosis and its complications that had precise intervention resulting in a favorable resolution.

Divertículo de Zenker: tratamento endoscópico versus cirúrgico

OBJETIVO: Revisar a evidência da segurança e efetividade dos tratamentos endoscópico e cirúrgico do divertículo de Zenker. MÉTODOS: pesquisa no MEDLINE, LILACS e SciELO por "Zenker's diverticulum or pharyngoesophageal diverticulum", e seleção de estudos para avaliação da qualidade e extração dos dados para uma metanálise. RESULTADOS: a pesquisa não localizou nenhum ensaio clínico randomizado. Encontramos cinco estudos comparativos não randomizados com grupo controle, com um total de 630 pacientes, 339 no braço endoscópico e 291 no cirúrgico. Os valores para segurança foram uma mortalidade de 0,29% e morbidade 7% para o tratamento endoscópico, e mortalidade 0,34% e morbidade 5% para o tratamento cirúrgico. O valor para efetividade foi 84% e 85%, respectivamente. O efeito das abordagens endoscópica e cirúrgica para o tratamento do divertículo de Zenker foi comparável, a odds ratio para morbidade foi 1,24 (0,56-2,74), e a odds ratio para o sucesso foi 0,66 (0,41-1,05). CONCLUSÃO: os estudos sobre o tratamento do divertículo de Zenker têm baixo nível de evidência e não são capazes de definir qual o melhor tratamento em termos de segurança e efetividade.

Divertículo faringoesofagiano: avaliação dos resultados do tratamento

OBJETIVO: Avaliar a evolução pós-operatória de pacientes com divertículo faringoesofagiano submetidos aos tratamentos cirúrgico e endoscópico. MÉTODOS: Foram analisados de maneira retrospectiva 36 pacientes com divertículo faringo-esofagiano atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP. Os pacientes foram distribuídos em dois grupos, na dependência do tratamento: grupo 1 (n=24) - diverticulectomia associada á miotomia do cricofaríngeo, através de cervicotomia esquerda; grupo 2 (n=12) - diverticulostomia endoscópica usando grampeador linear. RESULTADOS: A mortalidade operatória foi nula em ambos os grupos. Complicações precoces: grupo 1 - dois pacientes desenvolveram fistula cervical e outros dois, rouquidão; grupo 2 - sem complicações. Complicações tardias: grupo 1 - sem complicações: grupo 2: recidiva da disfagia em quatro pacientes (p=0,01). O seguimento médio foi 33 meses para o grupo 1 e 28 meses para o grupo 2. CONCLUSÃO: Os dois procedimentos foram eficazes na remissão da disfagia. O tratamento cirúrgico apresentou superioridade em relação ao endoscópico, com resolução da disfagia com um único procedimento. O tratamento endoscópico deve ser reservado para os mais idosos e portadores de comorbidades.

Dilatação cística do úraco e uroperitônio em touros: relato de cinco casos

Descrevem-se os aspectos clínicos da dilatação cística do úraco e uroperitônio em cinco touros. Os animais apresentaram, em datas distintas, distensão abdominal e diminuição da ingestão de alimentos e água, até culminar com inapetência, cerca de duas semanas após o aparecimento dos primeiros sintomas. Ocorreu distensão abdominal bilateral progressiva, que, no início do processo, era discreta e restrita ao quadrante inferior do abdômen; com cerca de duas semanas de evolução, o abdômen assumiu forma arredondada semelhante à pera. Observou-se bruxismo, atonia ruminal e desidratação. A abdominocentese revelou a presença de líquido amarelado com concentração de ureia superior a 200mg/dL. A concentração de ureia no soro sanguíneo variou de 220 a 280mg/dL e a creatinina de 65 a 82mg/dL. A ligadura do divertículo do úraco próximo ao vértex da bexiga foi eficaz nos quatro touros operados

Morphological aspects of the capybara stomach (Hydrochaeris hydrochaeris): Gross and microscopic structure

The digestive system of the capybara has been investigated because of its coprofagia habits, important for their absorptive activity. These species present differences in terms of gastrointestinal morphological characters when compared with other rodents. Macroscopiclly, the stomach of the capybara is constituted of the following parts: cardiac, pyloric, body, fundic and gastric diverticulum. It presents two curvatures, one big and another small. Externally, the presence of gastric bands (tenias) is observed. With regards to the volumetric view, the gastric capacity varies from 850 to 2010 ml, with an average of 1498.57 ml. So, the stomach of this animal can be classified as a simple stomach, in the format of a curved sack and similar to an inverted letter 'J'. The gastric mucous membrane presents a surface filled by numerous tortuous gastric folds and longitudinally distributed along all its extension. The mucous tunic also possesses recesses located among the successive gastric folds, which were denoted as gastric parts with numerous openings described as gastric pits. In the cardiac part, a glandular epithelium with cardiac glands is noticed containing a lot of parietal and mucous neck cells. The fundic part, body and gastric diverticulum contain proper gastric glands with main, parietal and mucous neck cells. Finally, the pyloric part has pyloric glands with two cellular types, mucous neck and parietal cells.

A NEW GENUS AND SPECIES OF CAMAENID FROM THE AMAZON RAINFOREST, BRAZIL (PULMONATA, HELICOIDEA)

Olympus nimbus, new genus and species, is described for the Amazon Rainforest, collected at Neblina Peak, Amazonas, Brazil. The taxon is clearly related to the camaenid genus Solaropsis because of conchological and anatomical attributes. However, the new taxon differs from its allies mainly in its smaller size (about 15 mm), its tall spire (almost as tall as wide), its narrow umbilicus, in lacking a bursa copulatrix diverticulum and a clear penial epiphallus, and by its complex internal penial organization. This paper also discusses the state of current knowledge of the South American Camaenidae.

COMPARATIVE ANATOMICAL STUDY OF TWO SPECIES OF SEMELE FROM THAILAND (BIVALVIA: TELLINOIDEA)

An anatomical description of two semelids from Thailand is presented, based on samples from Kungkrabaen Bay, Gulf of Thailand. The species are Semele sinensis A. Adams, 1853, and S. carnicolor (Hanley, 1845), both with Indo-Pacific distributions. Morphology in these two species is typically tellinoidean, each with a long internal ligamental element (resilium), a distance between the inner fold of the mantle edge and the other two folds, long and branched gastric ducts to the digestive diverticula, and a stomach diverticulum located in the posterodorsal corner of the gastric chamber, projecting posteriorly. The main anatomical differentiation between the two species is in the character of the labial palps.

Comparative morphology of the gas bladder in driftwood catfishes (Siluriformes: Auchenipteridae)

The gross morphology of the gas bladder is described and illustrated for representatives of most species and all valid genera of the Auchenipteridae (Siluriformes). Although, a simple cordiform gas bladder is present in some species of the family, others are characterized by their distinctive gas-bladder shape and diverticula disposition. An acute posterior end of the gas bladder characterizes Centromochlus heckelii and C. macracanthus, and is variably present in specimens of Auchenipterus. Tocantinsia piresi and Asterophysus batrachus have distinctive gas bladders differing in number of diverticula (two or many). The two species of Trachycorystes are diagnosed based on their gas bladder morphology: T. menezesi has a simple cordiform bladder, whereas T. trachycorystes has a pair of lateral diverticulum and, usually, a well-developed terminal diverticulum. Species of Auchenipterichthys are characterized by having a secondary bladder with simple chamber. Short or elongate and divergent terminal diverticula are exclusive to most cis-andine species of Trachelyopterus. Tetranematichthys and trans-andine species of Trachelyopterus share a well-developed secondary chamber or terminal diverticula ventrally or dorsally connected to the posterior chambers. The small-sized species of Ageneiosus have well-developed gas bladders with a pair of posterior diverticula, whereas large-sized species have a reduced gas bladder with tunica externa varying from non-, partially, or completely ossified. Eight phylogenetic characters are proposed based on the morphology of the gas bladder and associated structures in species of Auchenipteridae, and the evolution of those characters in the family discussed.
