Background: Although the first laparoscopic Nissen fundoplication was performed almost two decades ago, division of the short gastric vessels is still controversially discussed. The aim of this prospectively randomized trial was to evaluate the clinical and functional outcome following laparoscopic Nissen fundoplication with division versus saving of the short gastric vessels during short- and long-term follow-up.

Methods: Forty-one consecutive patients (30 men, 11 women) with gastroesophageal reflux disease were allocated to undergo Nissen fundoplication without division (group 1, n = 19) or with division (group 2, n = 22) of short gastric vessels.

Background: Impaired esophageal clearance is important in the pathogenesis of gastroesophageal reflux disease (GERD). It is unknown whether esophageal clearance improves following antireflux surgery. The aim of this study was to investigate the effect of laparoscopic Nissen fundoplication (NF), laparoscopic partial posterior (Toupet) fundoplication (PPF) or medical therapy on esophageal clearance.

Principles: The recently introduced robotic surgical systems were developed to overcome the limitations of conventional minimally invasive surgery. We analyse the impact of the da Vinci robotic system on general surgery.

Methods: The da Vinci operating robot is a telemanipulation system consisting of a surgical arm cart, a master console and a conventional monitor cart.

Background: From 1996, the entire number of fundoplications performed in Austria increased dramatically, favoring the laparoscopic technique. Despite good results, some patients experience failure of antireflux surgery and therefore require redo surgery if medical therapy fails to control symptoms. The aim of the study was to describe the refundoplication policy in Austria with evaluation of the postoperative results.

Background: Robotic surgical systems are most effective for operations in areas that are small and difficult to reach. Ideal indications for this new technology have yet to be established. The esophagus possesses attributes that are interesting for general thoracic robotic surgeons.

We report the first robotic resection of an ectopic mediastinal thyroid adenoma in a 72-year-old woman. This intervention was part of staged management for excessive bilateral cervical goiter with intrathoracic dispersion. The robotic resection was found to be feasible and safe.

Introduction: In patients with gastroesophageal reflux disease (GERD) it is still controversial as to which type of antireflux procedure-the Nissen or the partial posterior fundoplication-offers the lower rate of side effects in the long term.

Patients And Methods: In this follow-up study the Nissen fundoplication was performed only in GERD patients with normal oesophageal peristalsis. The partial posterior fundoplication was preserved for patients with weak peristalsis.

Introduction: Gastroesophageal reflux disease (GERD) is the most common foregut disease, with a great impact on quality of life and with intestinal, respiratory and cardiac symptoms and implications of carcinogenesis of the oesophagus. Medical therapy often fails, due to the complex pathophysiology of GERD. Surgery can cure the disease, since it is able to restore the anti-reflux barrier.

Purpose: Bilateral parathyroid exploration is still the standard therapeutic procedure for primary and recurrent hyperparathyroidism (HPTH). Since a unilateral surgical strategy that reduces surgical complications should not increase the risk of missing enlarged parathyroid glands, reliable preoperative imaging is the first requirement for this approach. This study was conducted to assess the accuracy of preoperative (99m)TcO(4)-(201)T1 pinhole subtraction single photon emission computed tomography (SPECT) compared with sonography.

Objectives: The da Vinci surgical robotic system was purchased at our institution in June 2001. The aim of this trial was to evaluate the applicability of the da Vinci operation robot for general thoracic procedures.

Methods: The da Vinci surgical system consists of a console connected to a surgical arm cart, a manipulator unit with two instrument arms and a central arm to guide the endoscope.

Background: An imaging-guided unilateral surgical approach in patients with primary hyperparathyroidism (HPTH) requires reliable preoperative localization procedures. Using present imaging techniques, 60% to 80% of patients with primary HPTH can be treated successfully with limited surgery. Thus, further improvement of diagnostic accuracy is required.

Background: Successful minimally invasive or imaging-guided operations in patients with primary, recurrent, and persistent hyperparathyroidism are based on the reliability of preoperative parathyroid localization studies. The CT-MIBI image fusion promises a higher diagnostic accuracy than current imaging procedures. The aim of our study was to assess its reliability in correctly detecting enlarged parathyroid glands.

Gastroesophageal reflux disease (GERD) is caused by a mechanically defective lower esophageal sphincter (LES) and may be worsened by impaired esophageal peristalsis. The aim of this study was to evaluate the efficacy of medical treatment depending on the function of the LES and esophageal peristalsis. We studied 128 GERD patients with mild esophagitis.

Percutaneous radio-frequency ablation (RFA) of liver tumors has been reported to be an effective approach. Skin implant metastases have been described after RFA of hepatocellular carcinoma. A 56-year-old man underwent resection of the transverse colon for an adenocarcinoma (pT3N2M0) following by adjuvant chemotherapy.

Background: This pilot study evaluated the role of the DaVinci operation robot for laparoscopic antireflux surgery.

Patients And Methods: A robot-assisted laparoscopic Toupet-fundoplication was performed on nine consecutive patients with severe gastroesophageal reflux disease using the DaVinci robot system. The operative procedure was performed in the same way as for the conventional laparoscopic procedure.

Background: Treatment strategies for idiopathic thrombocytopenic purpura (ITP) are still uncertain and its management is primarily empirical. The aim of this study was to investigate the role of splenectomy in the therapy of ITP and to evaluate whether medical or surgical treatment is superior.

Methods: Ninety-two patients with ITP were included in the study.

Background: Adjustable gastric banding and esophagogastric banding may affect the function of the lower esophageal sphincter (LES) and esophageal motility in the long-term. Both methods were evaluated in a prospective randomized trial.

Materials And Methods: Group 1 comprised 28 patients who underwent laparoscopic adjustable gastric banding and Group 2 consisted of 24 patients in whom adjustable esophagogastric banding was performed.

Barrett's esophagus is the most serious form of gastroesophageal reflux disease. It may develop due to uncontrolled chronic duodenogastroesophageal reflux and represents a premalignant abnormality. The question of the development of Barrett's esophagus and the progression to adenocarcinoma of the esophagus is addressed by comparison of the data available in the literature.

Background: Antireflux surgery (ARS) is a well established treatment for GERD (gastroesophageal reflux disease). The present study gives an overview of experience in Austria regarding the frequency of open and laparoscopic ARS and how Austrian departments meet the requirements for surgery.

Methods: A questionnaire was sent to 115 surgical departments in Austria to evaluate in how many institutions antireflux surgery (open and/or laparoscopically) was performed since 1990, and which pre- and postoperative tests were obligatory, optional, or not performed.

Background: Patients with gastroesophageal reflux disease (GERD) have alterations of gut neuropeptides, such as neurotensin (N) and motilin (M), which are resolved following antireflux surgery. Obesity is associated with GERD. Since the adjustable gastric band prevents gastroesophageal reflux in morbidly obese patients, this study was performed to investigate plasma levels of N and M before and after adjustable gastric banding (AGB).
