Introduction: Stage pN+ is a factor which determines the strategy for treatment of T3 rectal cancer. The sensitivity of preoperative imaging examinations revealing N+ is not entirely satisfactory. Risk factors that are associated with pT3pN+ stage and that are detectable by preoperative examination have not been reliably identified.

[Transgastric and transrectal hybrid NOTES cholecystectomy--experimental study].

Introduction: Natural Orifice Transluminal Endoscopic Surgery (NOTES) is a dynamically developing branch of miniinvasive surgery, whose aim is a minimazing abdominal wall injury. Many experimental studies describe the wide spectrum of the NOTES techniques in the animal model. The NOTES experiment begun in the porcine model for acquiring experience at the Surgical Departement in the University Hospital in Hradec Králové.

[Numbers of lymph nodes in large intestinal resections for colorectal carcinoma].

Introduction: Precise evaluation of lymph nodes in the surgical specimen is crucial for the staging and subsequent decision about the adjuvant therapy in colorectal cancer. Prognosis of the patients can be assessed only in cases when at least 12 lymph nodes in the surgical specimen are examined.

Aim Of The Work: To evaluate the radicalism of resections for colorectal carcinoma after introducing laparoscopic approach.
