- Bezoar gástrico e intestinal: caso clínico e revisão da literaturaPublication . Andrade, CS; Lopes, S; Pinheiro, C; Figueiredo, P; Tomé, L; Pinho, A; Martinho, F; Sofia, C; Leitão, MOs bezoars gastrointestinais são achados relativamente raros, apresentando uma variação regional na sua distribuição relacionada com diferenças na ingestão de alimentos ricos em fibras. A sua verdadeira incidência é desconhecida. A sua ocorrência apresenta uma tendência crescente, em provável relação com a maior taxa de cirurgias gastroduodenais realizadas no último século, consideradas factores de risco para a sua formação. Os autores apresentam o caso de um doente com antecedentes de cirurgia gastroduodenal, com quadro clínico caracterizado por vómitos alimentares, dor e distensão abdominal, paragem de emissão de fezes, anorexia e perda ponderal. O estudo complementar levantou a suspeita da existência de dois bezoars, um gástrico e um intestinal, a qual foi confirmada por laparotomia.Gastrointestinal bezoars are relatively uncommon findings and its distribution has a regional variation that correlates with differences in fibre enriched alimentary products ingestion. Its true incidence is unknown but its occurrence shows a growing tendency, which is probably related with the higher number of gastroduodenal surgeries performed in the past century, considered to be risk factors for bezoar formation. The authors present the case of a patient with a past history of gastric and duodenal surgery, admitted with vomiting, abdominal pain and distension, anorexia and weight loss. The diagnostic workup brought about the possibility of the existence of two bezoars, one gastric and one intestinal, which were confirmed by surgery.
- Jejuno-jejunal invagination caused by epithelioid sarcoma: a case reportPublication . Bento, A; Baptista, H; Pinheiro, C; Martinho, FINTRODUCTION: Jejuno-jejunal invagination is a rare condition and is usually caused by a benign lesion. We describe the case of a patient with a jejunal epithelioid sarcoma. Epithelioid sarcoma is a rare histologic subtype of sarcoma and few cases have been published. CASE PRESENTATION: A 70-year-old Caucasian man presented with vomiting and anemia. A jejuno-jejunal invagination was diagnosed and the patient underwent surgery. An epithelioid sarcoma of the wall of the jejunum was found on the invaginated ansa. CONCLUSION: To the best of our knowledge, an epithelioid sarcoma has never been reported to arise at the wall of the proximal jejunum or to present with jejuno-jejunal invagination
- Management of gallbladder polypsPublication . Matos, AS; Baptista, HN; Pinheiro, C; Martinho, FOBJECTIVE: Appropriate treatment and timing hinge on whether the lesion is benign or malignant. Study: A five years retrospective descriptive analysis was performed. Location : Department of General Surgery in Hospitals of the University of Coimbra. Patients: We present a series of 93 consecutive patients who had elective surgery for known gallbladder polyps, treated from January 2003 to December 2007. METHODS: An analysis was performed using clinical and radiological files of patients electively treated for gallbladder polyp. Ninety-three consecutive patients were evaluated, treated and followed in a Department of General Surgery in a Central Hospital in that period. Biographic, clinical and radiological data were compiled. RESULTS: In 91 patients a benign lesion was found. Two (2.16%) patients had adenocarcinoma. Among benign polyps, 73 (78,5%) were cholesterol polyps, 14 (15%) were hyper-plastic and 2 (2.19%) were premalignant adenomas. Mean diameter of benign polyps, excluding adenomas, was 6 mm. In 40 (43%) patients, multiple lesions were found. The mean diameter in the subset of malignant and premalignant polyps was 18.8 mm, in all instances these were found to be single lesions; and mean age at presentation was 57,7 years. CONCLUSION: Cholecystectomy is the appropriate surgical treatment for gallbladder polyps, when removal is warranted. Patients benefitting from surgery are those who are symptomatic, whose polyps exceed 10 mm in diameter and , have shown to be enlarging, to be sessile or broad-based, to have long pedicles;and also have . infundibular polyps, coexisting gallstones or changes on the gallbladder wall appearance at ultrasonography
