[Use of the EEA stapler in surgery of the rectum and rectosigmoid junction].

The application of mechanic sewing apparatus has obtained significant position in surgery of gastrointestinal tract. The EEA stapler (ILS Proximate) is improved, suitable and useful instrument for the performance of anastomosis after resection, and technically is equivalent to the normal suture techniques. It is especially convenient for the creation of low rectal anastomoses, thus definitive anus preter can be avoided. In 10 cases of rectal carcinoma, anterior resections and stapled anastomoses (3 were below 7 cm from anal border) were applied. In spite of insufficient number of surgically treated cases, surgical treatment was without technical problems and without postoperative dehiscence. Especially at low anastomoses, the importance of satisfactory suture techniques, adequate vascularization, avoidance of tissue tension, adequate selection and regulation of instruments are emphasized.

[Angiogenesis of gynecologic tumors studied with color Doppler].

Angiogenesis is obligatory event in solid tumors growth. Weak muscular layer in the newly formed tumoral vessels results in decreased resistance to blood flow and characteristic Doppler signal. The number and arrangement of the blood vessels differ between benign and malignant lesions as well. Parameters mentioned above enable a precise ultrasound differential diagnosis between benign and malignant tumors. Malignant uterine tumors are better perfused and have lower resistance to blood flow than benign ones. Benign lesions with secondary changes (necrosis) may have lowered resistance indices. The finding of pathological perfusion makes the diagnosis of endometrial carcinoma also very accurate. High sensitivity of the transvaginal color Doppler in detecting newly formed blood vessels in an early stages of ovarian cancer may establish this technique as a screening method for this still very high lethality disease.

[Comparison of open and laparoscopic appendectomy].

The first laparoscopic appendectomy was performed by Senn in 1982. Since then, the dilemmas about the validity of this operation in relation to open operation have persisted. Many authors presented the technique modifications and results that are very different. The retrospective results, cost, duration of hospital stay and postoperative recovery analyses for fifty patients in each group were done in this study. Laparoscopic operations were done by "two-handed" technique and in different ways of appendix and mesoappendix closing and cutting. Endoscopic linear cutters were used in the second part of the study. When comparing parameters, laparoscopic operation in relation to open operation is equally safe; quicker; with less postoperative pain; with less wound infections rate; with shorter hospital stay; with less staff time involved; with faster recovery and return to work; more expensive; with better cosmetic effect. In conclusion, laparoscopic appendectomy is better, although more expensive, than open operation, so it should be recommended.
