[Thyroid operation with routine frozen section--a self experience].

Fine needle aspiration biopsy (FNB) and frozen section (FS) may help to validate pre- and intraoperatively dignity of thyroid nodules, establishing the diagnosis of thyroid cancer. The role of frozen section is uncertain. Some authors suggest routine performance, some authors suggest selective use (in case of unclear FNB), some authors do not support the use of FS.

[Esophageal operations with thoracoscopy].

Between 01.07.1992 and 30.

[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.
