Abstract: background: reflux esophagitis complicated by stenosis and shortening of the organ is a difficult disease to surgical treatment with frequent failure. the collis gastroplasty associated with a partial or total fundoplication can be employed in this situation. objective: to evaluate the technique of fundoplication with partial or total collis gastroplasty in dogs. methods: seven dogs underwent a collis-lind (group a) and four to collis-nissen (group b) after myotomy of the gastroesophageal junction; reflux was evaluated with measurements of ph and pressures in the esophagogastric transition with microtransducer. results: after myotomy reflux occurred freely in all animals. however, after collis-lind or collis-nissen procedures, it not ocurred spontaneously. the application of manual pressure on the stomach caused reflux in 28.5% of animals in group a. the assessment of pressures in the surgical specimen showed no difference in the area of high pressure in both groups. conclusion: the collis-lind and collis-nissen procedures prevent gastroesophageal reflux. the pressure measurements and the extension of the high pressure zone were similar in both groups.

Abstract: background: epiphrenic diverticulum is a rare condition in clinical practice usually presented by few symptoms such as dysphagia. before the advent of the videosurgery, it's surgical treatment was performed by a left thoracotomy or laparotomy and resection of the diverticulum, associated or not with myotomy in the esophagogastric junction. today, this procedure has been accomplished, by laparoscopy with very good results, leading to a better postoperative recuperation. methods: we present five patients with epiphrenic diverticulum that were treated by videolaparoscopy. three of them were females and their ages varied between 37 and 64 years old. all patients were submitted to an endoscopy and x-ray to confirm the diagnosis; three were submitted to a manometry that showed unspecific motility alterations. results: resection of the diverticulum was performed successfully by videolaparoscopy in all cases. one patient showed esophageal leakage after 8 days with normal control postoperative x-ray. the hospital length of stay varied between 7 and 21 days, and disphagya relief was achieved in all patients, with a follow-up between two to eleven years. conclusion: videolaparoscopic surgical repair for epiphrenic diverticulum, associated or not to myotomy of the esophagogastric junction, is the treatment of choice. it is associated with less pain and complications, with a shorter length of stay. this technique is safe and efficient for treatment of the epiphrenic diverticulum.

Abstract: OBJETIVO: Avaliar e comparar a qualidade de vida de pacientes esofagectomizados para tratamento de adenocarcinoma da jun o esofagogástrica e de carcinoma epidermoide. MéTODOS: estudo transversal no pós-operatório de doentes esofagectomizados por adenocarcinoma da jun o esofagogástrica (Adenoca) e carcinoma epidermóide (CEC), empregando o questionário SF-36 aplicado em 24 pacientes (10 por Adenoca e 14 por CEC), a partir do 5o mês de pós-operatório, incluindo os sintomas clínicos e a varia o de peso. RESULTADOS: A avalia o da QV mostrou melhor resultado de capacidade funcional (p=0,018) para o grupo Adenoca. Houve correla o entre os domínios "saúde mental" e "limita o por aspectos emocionais" (p=0,003) e entre "dor" e "limita o por aspectos físicos" (p=0,003) nos dois tipos histológicos. A perda de peso foi maior nos esofagectomizados por Adenoca (45,9Kg), sem diferen a significativa entre o IMC atual (p>0,66). A disfagia foi relatada por 83,3% dos pacientes, a anorexia por 58,3%, a dificuldade de mastiga o por 42%, a náuseas e os v mitos por 41,7% e a diarréia por 29,2%, sem correla o com a QV relatada (p>0,05). CONCLUS O: O escore mais alto para capacidade funcional indica que o paciente com Adenoca foi capaz de realizar todo tipo de atividade física, incluindo as mais vigorosas em um nível maior que o paciente com CEC. Alguns sintomas persistiram no pós-operatório, porém n o interferiram na qualidade de vida dos pacientes. OBJECTIVE: To evaluate and compare the quality of life (QOL) of patients undergoing esophagectomy for treatment of adenocarcinoma of the esophagogastric junction and squamous cell carcinoma. METHODS: We conducted a cross-sectional study in postoperative patients submitted to esophagectomy for adenocarcinoma of the esophagogastric junction (ACA) and squamous cell carcinoma (SCC), using the SF-36 questionnaire applied in 24 patients (10 ACAs and 14 SCCs), from the 5th months postoperatively, including clinical symptoms and weight change. RESULTS: The assessment of QOL showed the best functional capacity (p = 0.018) in the ACA group. There was a correlation between the fields "mental health" and "Role of Emotions" (p = 0.003) and between "pain" and "physical aspects limitation" (p = 0.003) in both histological types. Weight loss was greater in ACA (45.9 kg), with no significant difference between current BMI (p> 0.66). Dysphagia was reported by 83.3% of patients, anorexia by58.3%, chewing difficulty by 42%, nausea and vomiting by 41.7% and diarrhea by 29.2%, with no correlation with QOL reported (p> 0.05). CONCLUSION: The high

Abstract: purpose: steatorrhea is one of the most common complications in reconstruction after total gastrectomy. many reconstruction techniques after total gastrectomy have been developed in order to avoid these undesirable effects, but each one of them has some inconvenience. in this experiment, a modified rosanov technique that keeps duodenal transit, evaluation of fat absorption after gastrectomy was tested. methods: three groups of rats with the same characteristics were used. total gastrectomy was performed in two groups: one was operated on and transit was reestablished by the roux-en-y technique (group y), while the other was submitted to the modified rosanov technique (group r). following surgery, a handmade hyper fatty diet (11% of fat) was offered. a third group (control - group c) was not operated but was submitted to the same conditions of the other groups, and used for reference steatocrit values. the animals underwent laparotomy 14 days after surgery and had their feces collected from cecum to determine their steatocrit by analysis of their values. results: steatocrit values for groups r and c (mean 5.16% and 4.15% respectively) were similar (p > 0.1), while group y had significantly higher values (mean = 28.18%, p = 0.0001 - p < 0,05). this was attributed to the fact that group r animals had their duodenal transit patent, decreasing the complications expected in the roux-en-y reconstruction. conclusions: steatorrhea in the modified rosanov technique was similar to the control group, while roux-en-y reconstruction presented higher steatorrhea and fat malabsorption.

Abstract: background: the esophageal stenosis secondary to the ingestion of caustic products is frequent in brazil, mainly due to an attempt suicide. the barrett's esophagus is consequence of the chronic gastroesophageal reflux. the literature consulted showed that are a rare association. casuistic and methods: from 1981 to 2000 were admitted and treated in the "gastrocentro" state university of campinas, sp, brazil, 120 patients presenting caustic stenosis of the esophagus, and during the follow-up were found nine cases with barrett's esophagus associated (7,5%). the time of caustic ingestion varied from 4 years to 54 years (mean 29 years), and they were four males and five females, eight whites and one black, with the mean age of 57,7 years (43 to 72 years). results: all the cases presented dysphagia and the flexible upper endoscopy showed stenotic areas and caustic esophagitis sequels. three patients referred symptoms of gastroesophageal reflux, but hiatus hernia were found in only one case. the barrett's esophagus was found in the middle third of the esophagus above the stenotic areas in three cases, and in the distal third in six cases. the dysphagia was treated with periodic esophageal dilatations. two patients presenting severe symptoms of reflux were submitted to modified nissen fundoplication by videolaparoscopy, with good results. conclusions: the barrett's esophagus in these patients could be associated to the caustic ingestion, because it is not situated in the distal third of the esophagus, as commonly found in reflux esophagitis. its is very important the follow-up and biopsies of the barrett's esophagus, due to the possibility of malignancy.

Abstract: RACIONAL: A estenose esofágica secundária à ingest o de produtos cáusticos é freqüente no Brasil, principalmente como tentativa de suicídio. O es fago de Barrett surge como conseqüência do refluxo gastroesofágico cr nico. A literatura pesquisada mostrou que esta associa o é muito rara. CASUíSTICA E MéTODOS: De 1981 a 2000 foram admitidos e tratados no Gastrocentro-UNICAMP (Universidade Estadual de Campinas, SP.) 120 doentes com estenose cáustica do es fago e durante o seguimento destes, foram encontrados 9 casos associados com o es fago de Barrett (7,5%). O tempo de ingest o do cáustico variou de 4 a 54 anos (média de 29 anos) e eram quatro homens e cinco mulheres, oito brancos e um negro, com idade média de 57,7 anos (43 a 72 anos). RESULTADOS: Todos os casos apresentavam disfagia e a endoscopia digestiva alta flexível mostrou áreas de estenose e seqüelas de esofagite cáustica. Três pacientes referiram sintomas de refluxo gastroesofágico, mas hérnia de hiato foi encontrada em apenas um caso. O es fago de Barrett foi encontrado no ter o médio do es fago em três casos, acima das áreas de estenose, e nos demais, no ter o distal. A disfagia foi tratada com dilata es esofágicas periódicas. Dois pacientes apresentando sintomas de refluxo grave foram submetidos a fundoplicatura à Nissen modificado através de videolaparoscopia, com bons resultados. CONCLUS ES: O es fago de Barrett nesses doentes poderia estar associado com a ingest o de cáustico, porque nem sempre esteve associado à esofagite por refluxo. é muito importante o seguimento desses doentes e realiza o periódica de endoscopias digestivas com biopsias do es fago de Barrett, devido à possibilidade de maligniza o.
