[Intraoperative pancreas puncture cytology].

In the case of 10 to 15% of surgical patients with a pancreatic disorder an intraoperative diagnosis had to be made when a preoperative diagnosis had not yielded a definite result. Fine needle aspiration biopsy ( FNAB ) of the pancreas provided the basis for intraoperative differentiation of malignant and benign pancreatic processes. 244 pancreatic biopsies were carried out in 100 patients. It was possible to make a statement in 99% of the cases, with 65 malignant and 35 benign changes. In 83% the cytological diagnosis was correct; the method yielded incorrect-negative results in 7% of the cases. In 9% the presence of tumour cells was only suspected. There were no incorrect positive cancer diagnoses. FNAB caused no postoperative complications. Intraoperative bleeding after FBAB had to be stopped with a suture in one case. Transitory, asymptomatic hyperamylasemy must be expected in 25% of the patients after FNAB . This diagnostic technique is recommended in preference to the histological tissue removal methods because of its low risk factor. At least 2 biopsies of the suspect area with 2 smears are required, as a training in this diagnostic technique.

[Liver biopsy in surgery of the gallbladder].

Biopsy of the liver with the menghini needle was done as a routine diagnostic procedure during surgery in 581 cases. During earlier decades morphological changes of the liver could be demonstrated by that procedure in 80-100% of the patients. In contrast such changes could be found only in 55% of our cases; in 5,5% these changes were severe. From these numbers it should be concluded that liver biopsy during gall bladder surgery is not necessary as a routine procedure. If patients are selected for biopsy on the basis of history, ultrasonography, laboratory data and intraoperative microscopical liver findings this procedure is necessary only in 14% of the cases, complication rate being 0,09%. In this particularly selected group changes of the liver can be found in 90,4%, severe changes in 33% of the cases. Pathological changes of the liver are likely to occur in 65-91% of patients with complicated gall stone disease and/or accompanying diseases like diabetes, obesitas, alcoholism, or a history of hepatitis. In this particular group biopsy and histological examination during surgery seem to be indicated as it was the case before.

[Heterotopic pharyngeal hypophyseal adenoma].

Juvenile fibroma, carcinoma and sarcoma are the most frequent tumors of the nasopharynx. Ontogenetic tumors that originate from the base of the skull are found very rarely. The case reported deals with a heterotopic pharyngeal pituitary adenoma, that started growing from the epipharynx.

[Starch granulomas caused by glove powder].

Simultaneously with the introduction of new surgical gloves with heavily powdered outside surfaces, complications repeatedly occurred after laparotomies. Four patients were compelled to undergo a second operation, during which peritoneal fibrous adhesions and foreign body granulomas of omentum were found. After resection of the omentum, healing proceeded without disturbance. Five different types of surgical rubber gloves were examined by scanning electron microscopy. In addition, the effect was evaluated of different commonly applied preoperative rinsing procedures for gloved hands. The amount of powder found on the outside of regularly used gloves varied between 0.059 and 0.287 g. The effect on the proper healing process by starch powder deposits found on the outside of surgical gloves as well as upon optimal cleansing of the surgical teams' hands will be discussed.
