[Anal pressures after stapler hemorrhoidectomy - a prospective analysis of 33 patients].

Purpose: Determination of the effects of staplerhemorrhoidectomy as a new method of surgery, type of staplers and way of anal retraction on anal pressures.

Patients And Methods: In 33 patients (mean age 56 ys.) with third degree hemorrhoids who underwent staplerhemorrhoidectomy in the Marienhospital Gelsenkirchen between 1998 and 1999, anal resting and squeezing pressures were measured before and after the operation.

[Cholecystectomy via a surgical tube in 800 patients].

800 gallbladders have been removed by means of an operation tube. The diameter of this operation tube is -depending on the situation -2,3 or 4 cm. The operation is practicable by one surgeon and one instrument sister.

[Therapy of acute esophageal varices hemorrhage. Animal-experiment and clinical results].

Next to the operative therapy of portal hypertension during non bleeding intervals using the various portacaval shunts, sclerotherapy is being chosen more and more especially in the acute phase. In this animal experiment the hemodynamics of vasopressin were compared to those of the derivative, TGLVP, with prolonged action. While both showed the same effect on the hemodynamics, the TGLVP treatment hardly changed the oxygen supply to the liver.

Endoscopic insertion of feeding tubes a new method for the management of upper digestive tract stenosis.

For patients requiring artificial feeding over a lengthy period, enteral alimentation via feeding tubes has proved to be the most practicable, and least harmful, method. The paper describes a new endoscopic method that facilitates the introduction of a feeding tube, even through stenoses of the upper digestive tract, or through areas of suture leakage after abdominal surgery. The method was successfully employed, without complications, in 13 patients; it was tolerated without serious inconvenience, and can be performed by the endoscopist and his assistant nurse.
