[Small bowel perforation caused by intestinal dissemination of pulmonary tuberculosis due to biological therapy].

Case review: The authors present a case of a 78-year-old female patient who previously, as a teenager, had been treated for pulmonary tuberculosis. The biological therapy for subsequent inflammatory bowel disease in 2015 caused a flare up of the respiratory symptoms after 60 years of being asymptomatic, and the patient also developed acute abdomen. She required emergency laparotomy and small intestine segment resection was performed due to perforated ileum.

[Dirofilaria in the abdominal cavity].

Number of cases of filariasis have been recently reported in the Hungarian medical literature, most of them caused by Dirofilaria repens . Dirofilaria repens is a mosquito-transmitted filarioid worm in the subcutaneous tissue of dogs and cats. Human infection manifests as either subcutaneous nodules or lung parenchymal disease, which may even be asymptomatic.

[Intraabdominal foreign body caused diagnostic difficulty].

The problem of retained foreign body in the abdominal cavity following surgery is permanent and almost impossible to solve for abdominal surgeons. We present the story of a 49-year-old woman operated on because of a cystic lesion formed around a swab which was left in the abdominal cavity during open cholecystectomy ten years ago. We did not realise the nature of the lesion before the operation or by examination during the operation.

[Pancreas head resection combined with resection of the superior mesenteric vein: extensive procedure for tumors of the pancreas head].

Surgical treatment for locally advanced cancer of the pancreas head with vascular invasion is controversial. It is regarded as a contraindication for resection by most surgeons, others perform resection involving the vessel. We performed pancreaticoduodenectomy with vascular resection in a 61 year old patient.
