Análise radiológica das alterações gastrintestinais após cirurgia de Fobi-Capella

OBJETIVO: Estudar os achados radiológicos encontrados na seriografia digestiva alta no pós-operatório tardio de cirurgia de Fobi-Capella. MATERIAIS E MÉTODOS: Estudo radiológico de 41 pacientes realizado seis a nove meses após a cirurgia de Fobi-Capella. RESULTADOS: As alterações encontradas foram hérnia hiatal (17%), refluxo gastroesofágico (19,5%) e deslizamento do anel (4,8%). Os achados menos freqüentes foram fístula enterocutânea (2,4%), estenose da anastomose gastrojejunal (2,4%), bezoar (2,4%) e não-visualização do anel em decorrência da sua retirada por intolerância (2,4%). As alterações anatômicas da cirurgia foram claramente demonstradas. CONCLUSÃO: O estudo foi capaz de demonstrar as alterações anatômicas e as complicações da cirurgia de Fobi-Capella.

Perfuração gástrica por tricobezoar

Bezoars are uncommon foreign bodies found in the stomach and intestines. They are usually secundary to "strange" or "weird" alimentary habits. The contents may include hait; stones, vegetal fibers and others. Diagnosis is generally made due to complications, mainly parcial or complete obstruction of the segment affected. Bleeding and peiforation may also occur: This paper describes a case of a 14-years-old female patient, who presented herself to lhe Emergency Room and was diagnosed as having a gastric peiforation due to a trichobezoar that was 15 cm long and weighted 900g. A review of lhe literature and comments about diagnosis and management are presented.

Tricobezoar gástrico

Bezoar is a foreign body in the digestive tract originated from ingestion of varied substances, mainly vegetal hair or coats, staple fibers among others. We present a case of a 16-year-old female with trichotillomania history of approximately 5 months, diagnosed through clinical evidence of traumatic alopecia made by her dermatologist. Though asymptomatic the presence of tricobezoar was suspected and confirmed through digestive seriography and high digestive endoscopy. The patient was operated on for gastrotomy and removal of bezoar, with good postoperative follow-up, except for surgical wound infection.

Extração de fitobezoar gástrico por videolaparoscopia: considerações técnicas originais

Videolaparoscopic surgery has been used for treatment of almost all surgical abdominal diseases, mainly where there are no large ressections, or operative field is limited. In these situations, laparoscopic surgery has the advantages of less morbidity, quick recovery and good cosmetic results. Bezoars removal, or its mobilization, is probably included in these possible proceedings. Three non-laparotomic procedures were described: 1. endoscopic-laparoscopic; 2. videolaparoscopy and mobilization of intestinal bezoar to the cecum; 3. laparoscopy and gastrotomy for bezoar removal, through suprapubic incision or the umbilical punction. There have been only two publications describing the videolaparoscopic method for bezoar removal, and the methods applied can be complications or morbidity related. We describe one case where the applied technique is simple and easy to perform, time saving and probably less complications-related. This technique, with four trocars, utilized a plastic bag besides the stomach to be opened, followed by gastrotomy, bezoar removal and immediate introduction in the plastic bag, suture of gastrotomy and removal through the left subcostal trocar. This technique was feasible and easy to perform, with short operative time, and there were no intra or post-operative complications; the patient was discharged in the second post-operative day, and is without further problems after one year follow-up. We believe that this could be an adequate technique to perform laparoscopic gastric bezoar removal, and the rigid sequence of operative events allows a quick procedure, with minimal contamination. The videolaparoscopy seems to be an adequate access to surgical treatment of gastro-intestinal bezoars, with or without obstruction, and should be the ellected the procedure of choice to begin the surgical treatment, with convertion to laparotomy in case of any intra-operative adversity.

Úlcera gástrica terebrante e pancreatite aguda provocadas por tricobezoar

Bezoar is a foreing body whitin the digestive tract originated from ingestion of varied substances, mainly vegetal fiber or hair. We present a case of a 14-year-old girl with trichotillomania, gastric trichobezoar, gastric ulcer and acute pancreatitis. The patient was operated on for anterior gastrotomy and removal of trichobezoar, with good postoperative follow-up. We illustrate this case to emphasize the need for recognition of gastric ulcer with acute pancreatitis and surgical management.

Obstrução gastrointestinal por fitobezoar na cirurgia bariátrica

OBJETIVO: O objetivo do presente estudo foi avaliar o quadro clínico, a incidência, os fatores predisponentes e a evolução de pacientes com fitobezoar após Gastroplastia Vertical e Y de Roux. MÉTODO: No período de Novembro de 1997 à Janeiro de 2004, foram realizadas 512 operações para o tratamento da Obesidade mórbida, seguindo a técnica proposta por Fobi/Capella (Septação gástrica com reconstituição em Y de Roux Proximal). Em dez pacientes foram identificados fitobezoar. RESULTADOS: A incidência de fitobezoar, causando algum tipo de obstrução gastrointestinal, foi de 1,95% (10/512). Todos os casos de fitobezoar estavam relacionados ao fio de sutura inabsorvível do tipo prolene. Sete pacientes apresentaram quadro semioclusivo e de obstrução intestinal e foram tratados com laparotomia exploradora, ressecção da anastomose enteroenteral e confecção de nova enteroenteroanastomose. Nos três pacientes com bezoar situado na anastomose gastrojejunal, a secção do fio e a retirada do corpo estranho foram realizadas por endoscopia digestiva alta. CONCLUSÕES: A confecção de anastomose intestinal com fio inabsorvível predispõe a formação de bezoar em pós-operatório de gastroplastia.

Tricobezoar gástrico: relato de caso

Bezoars are foreign bodies impacted in the digestive tract resulting of their ingestion and accumulation, involving mainly the stomach. The most common types are phytobezoars, contaning vegetables, fiber and seed and the trichobezoar, made of hair. The present case is the description of a 25-year-old female with nonspecific dyspeptic symptoms associated to intestinal habit change. The diagnosis was suggested by Computerized Tomography in association with clinical history - initially omitted by the pacient - of trichophagia for 10 years. Treatment consisted of Anterior Gastrotomy and remotion of the bezoar.
