[Endoscopic papillotomy with a needle knife].

The authors describe their experience with the use of a knife needle in endoscopic papillotomy. They use this method when it is not possible to reach the derivation of the bile duct by means of a classical papillotomy, or for opening a stenotic papilla. They made a total of 68 operations, 89.7% of which were successful in the first place, the total success rate being 98.53%. No serious complications were recorded. The authors recommend the method provided its is used by an experienced endoscopist.

[Surgical endoscopy--analysis of 6 years' activity].

Fibroscopy of the digestive system which in the majority of developed countries is quite common is in our country still not available in an adequate extent. The authors evaluate their experience in a surgical department covering a six-year period. A total of 4436 fibroscopic examinations were made incl. 3821 gastroscopies 615 ERCP and examinations of the papilla Vateri. They describe their experience with urgent endoscopy on account of haemorrhage into the GIT, pancreatitis or cholangitis. They emphasize the advantages of a maximal extension of endoscopic methods and their advantages, as compared with classical examination methods.

[Laparoscopic cholecystectomy without cholangiography].

The results assembled in a group of 260 patients subjected to laparoscopic cholecystectomy without i.v. cholangiography (0.38% residual stones, entirely successful perioperative endoscopic treatment, no biliary lesion) confirm that a low incidence of residual cholelithiasis, elimination of revision on account of concrements in the bile duct and absence of biliary lesions can be achieved without obligatory preoperative cholangiography even in a non-selected clinical group. When therapeutic "splitting" is used, peroperative selective cholangiography is not necessary.

[Emergency endoscopic papillotomy].

The authors describe their experience with urgent endoscopic procedures of the papilla Vater. They consider septic cholangitis and acute pancreatitis indications for endoscopic papillotomy. The authors made a total of 27 operations, incl. 22 on account of pancreatitis and five on account of cholangitis. One female patient with necrotizing pancreatitis caused by a protracted sepsis and multiorgan failure, died. Otherwise there were no serious complications; after the majority of operations a steep drop of pathological laboratory values was recorded. One of the most important factors for successful endoscopic intervention is in the authors' opinion rapid action. With regard to the favourable initial results the authors recommend a detailed multi-centre prospective randomized study.

[Laparoscopic cholecystectomy: early results in the initial non-selected group of 50 surgical patients].

Early results of an initial non-selected group of 50 laparoscopic cholecystectomies (mean hospitalization 3.5 days, 6% conversions, no serious complications, no revisions, morbidity due to minor complications 6.3% and saved costs of postoperative hospital treatment 44.6%) confirm that this operation is feasible, safe, preferred by patients and well tolerated economical definitive treatment of cholecystolithiasis. On these grounds it is becoming a method of first choice. The safety of patients is ensured by steady care of the surgeon and his adequate training according to generally accepted principles.

[Peroperative endoscopic papillosphincterotomy].

The authors describe their experience with combinations of endoscopic and surgical procedures when dealing with stenoses of the papilla Vateri. They give a detailed account of the endoscopic phase of surgical intervention. In their opinion the most important thing is exclusion of duodenotomy which should reduce the risk of a duodenal fistula. Another important advantage is more rapid convalescence and a shorter hospitalization period as well as a shorter time required for the intervention. Next the authors discuss possible complications described in the literature and their relationship to endoscopic papillotomy. The authors evaluate contemporary possibilities of endoscopic treatment and emphasize the necessity to extend the use of endoscopic methods in everyday surgical practice.

[Endoscopic bipolar coagulation of acute gastroduodenal hemorrhage].

The authors describe one possible way of endoscopic haemostasis, i.e. by bipolar coagulation. First they give an account of the principle of the method and technique of coagulation. Then they demonstrate on their own group of patients with haemorrhage into the gastroduodenum a 71% effectiveness of haemostasis by this method. In another 10% a temporary effect was achieved with the possibility of effective supplementation of the blood volume and thus an improved prognosis of surgery. In case of failure, in particular haemorrhage according to Forest Ia, they warn against any delay of surgery.

[Hemostatsis during liver resection using the Leister Hot-Jet coagulator].

The authors present their own experience with the use of a hot-jet coagulator in resections of the liver. The principle is based on contact-free transmission of thermal energy by means of a current of hot air to achieve haemostasis and tissue coagulation. They mention the use of the apparatus in animal experiments and in resections of the liver in nine patients. They recommend the procedure as one possibility of haemostasis where conventional methods do not affect haemostasis.
