The Winchcombe meteorite, a unique and pristine witness from the outer solar system.

Direct links between carbonaceous chondrites and their parent bodies in the solar system are rare. The Winchcombe meteorite is the most accurately recorded carbonaceous chondrite fall. Its pre-atmospheric orbit and cosmic-ray exposure age confirm that it arrived on Earth shortly after ejection from a primitive asteroid.

Is rectal indomethacin effective in preventing of post-endoscopic retrograde cholangiopancreatography pancreatitis?

Aim: To investigate the effectiveness of rectally administered indomethacin in the prophylaxis of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis and hyperamylasaemia in a multicentre study.

Methods: A prospective, randomised, placebo-controlled multicentre study in five endoscopic units was conducted on 686 patients randomised to receive a suppository containing 100 mg indomethacin, or an inert placebo, 10-15 min before ERCP. Post-ERCP pancreatitis and hyperamylasaemia were evaluated 24 h following the procedure on the basis of clinical signs and laboratory parameters, and computed tomography/magnetic resonance imaging findings if required.

Intraabdominal abscess managed successfully via the laparoscopic approach.

A rare complication of laparoscopic fundoplication-an intraabdominal abscess located between the fundus and the caudate lobe of the liver-is described. A 41-year-old man had undergone a laparoscopic Nissen-Rossetti fundoplication for longstanding gastroesophageal reflux disease. On the 5th postoperative day, the patient's general condition became worse, and he developed intermittent-remittent fever (40 degrees C), an elevated white blood cell count (WBC), and an accelerated sedimentation rate.

[Result of Panzytrat 25000 therapy following total gastrectomy].

Thirteen patients who had undergone total gastrectomy because of gastric cancer in 11 cases and gastric lymphoma in 2 cases (6 female, 7 male) at the 3rd Department of Surgery, Semmelweis University, Medical School have been followed up. The length of follow up period varied between 7.5 months and six years.

Biliary tract complications in laparoscopic cholecystectomy. A multicenter study of 148 biliary tract injuries in 26,440 operations.

Background: The higher risk of biliary tract injury is considered the most significant disadvantage of laparoscopic cholecystectomy.

Methods: A national multicenter retrospective study was performed to determine the frequency, etiology, and treatment of biliary tract injuries between January 1, 1991, and December 31, 1994. Follow-up was by questionnaire.

Investigation of effect of lesser curvature seromyotomy of the stomach in animal experiments.

The effectiveness of seromyotomy of the lesser curvature of the stomach--the simplified version of proximal selective vagotomy--was investigated in eleven dogs. Decreased acid secretion was proved with congo red test and pH measuring by glass electrode. No significant damage to the motor function of the stomach was found with scintigraphy.

Complications of laparoscopic cholecystectomy in Hungary: a multicentre study of 13,833 patients.

Objective: To report our countrywide experience of laparoscopic cholecystectomy with particular reference to complications.

Design: National multicentre retrospective study.

Setting: 71 university departments and public hospitals in Hungary.

[Laparoscopic cholecystectomy causing injury to biliary tracts. Analysis of the results of 26,440 operations in Hungary].

The authors analyse the etiology, diagnosis, treatment and outcome of 148 biliary tract injuries in connection with 26,440 laparoscopic cholecystectomies performed in 89 domestic institutes between January 1st, 1991, and December 31st, 1994. There was no significant correlation between the amount of laparoscopic cholecystectomies performed in one institute and the incidence of biliary tract injuries and postoperative bile leakage (wide range of figures were found in different institutes), but in the second year of practice, the incidence of both complication decreased (there was statistically significant difference between the regression co-efficients). There was no significant correlation between the laparoscopic cholecystectomies performed and the rate of conversion, but the co-efficient of the regression curve showing the correlation of the absolute number of laparoscopic cholecystectomies and conversions significantly decreased in the second year of practice.

[Bile duct injuries in laparoscopic cholecystectomy. A computerized analysis of 148 lesions in 24,440 operations in 89 Hungarian institutes (publication by the Hungarian Society of Surgery)].

The authors analyse the etiology, diagnosis, symptoms, treatment and outcome of 148 biliary tract injuries in connection with 26,440 laparoscopic cholecystectomies performed in Hungary. In univariant analysis, the type of injury, the primary treatment modality did not affect the outcome of injury or the necessity of reoperation; in multivariant analysis, the outcome is significantly influenced adversely by the necessity of repeated interventions and higher age. Disturbances in the identification of anatomic structures lead significantly to more main bile duct injuries than lesions in the region of the cystic duct and cause more complete trans-sections than partial lesions.

Long-term clinical results of highly selective vagotomy performed between 1980 and 1990.

A retrospective analysis was conducted of 778 patients who underwent highly selective vagotomy between 1980 and 1990. Surgery was performed for duodenal ulcers without any complications in 485 (62.3%) patients; for duodenal ulcers with complications such as stenosis, bleeding, or perforation in 270 (34.

Unexpected gallbladder cancer and laparoscopic surgery.

Case histories of three patients who underwent laparoscopic cholecystectomy for unexpected gallbladder cancer are reviewed. Port-site recurrence was observed in two of them. In one patient whose abdominal wall recurrent tumor was excised, a new recurrence developed, but after the reexcision she is symptom-free 10 months after the last procedure.

[Laparoscopic cholecystectomy and cancer of the gallbladder].

Performing a series of 960 laparoscopic cholecystectomies we have removed 3 unsuspected gallbladder cancers. In one case we have observed the development of trocar site abdominal wall metastasis twice. After resection and reresection of the metastases the patient is symptom-free in the 14th month.

[The role of sonography in laparoscopic cholecystectomy].

Between January 1991. and December 1993. in the 3rd Surgical Department of Semmelweis Medical University 735 laparoscopic cholecystectomies were performed.

The role of invasive sonography in the differential diagnosis and treatment of intraabdominal fluid collections.

Sixty-nine ultrasound-guided interventions (23 punctures and 46 drainages) were performed on 51 patients with the suspicion of intraabdominal abscess or another type of fluid collection in a prospective-controlled study. Of the procedures, 58.8% were carried out following surgery, while in 41.

Surgical relations of Crohn's disease and the frequency of recurrence.

There is no disease that would have as many and variable complications as Crohn's disease. One of the most common complications is bowel obstruction which can be caused by the angulation of the bowel or by inflammation, or by formation of granulation tissue (32.3%).

Thoracoscopic lung resection by the help of Nd:YAG laser.

The Swedish surgeon Jacobaeus was the first to use a lighted cystoscope for the lysis of pleural adhesions /5/. The same author reported, in 1921, five cases of intrathoracic malignancies diagnosed by thoracoscopy /6/. After the appearance of video-assisted cholecystectomy and abdominal surgery, video-assisted thoracic surgery (VATS) also occupied a major share in thoracic surgery.

[The effect of lesser curve seromyotomy of the stomach in animal experiments].

The authors investigated the efficiency of the seromyotomy of the lesser curvature of the stomach in 11 dogs. Reduction of the acid production was verified by glass electrode pH measuring of the gastric mucosa. Scintigraphic examination showed that the operation did not damage the motor function (motility) of the stomach.

[Laparoscopic cholecystectomy].

Traditional cholecystectomy has been the standard surgical treatment of the gallstone disease for more than 100 years. The technical development led to a new surgical procedure and its rapid acceptance. This is laparoscopic cholecystectomy.

[Complications of Crohn disease, surgical indications, surgical solutions and recurrence].

There is not another disease, of which complications would be such frequent and various as of Crohn's disease. One of the most common complications is intestinal obstruction, caused by angulation and stricture, as a result of inflammatory granulomas. Fistulas between affected intestines and cavital organs or the abdominal wall can also often be observed.

[Etiology, symptomatology, diagnosis, differential diagnosis and management of Crohn disease].

The non specific, chronic, inflammatory, granulomatous Crohn's disease is not common in our country. Despite wide clinical and experimental experiences, its etiology hasn't been cleared yet. Its symptoms are especially various.

[Childhood accidents].

A survey of accidents in a period of one year in County Vas, Hungary was performed. The injury of children in the age-group of 0-14 was found in case 5841 i.e.
