Background And Aims: Colorectal cancer is one of the leading causes of cancer death. We analyzed the value of standardized, risk-independent postoperative surveillance.

Materials And Methods: Between 1995 and 2001, 564 patients with colorectal cancer underwent standardized oncologic resection.

Background: By application of a newly developed device for invasive pressure measurements, we have investigated band adjustments monitored by in vivo intraband pressures. With access to the port of the gastric banding device, pressures can be recorded inside the band system at rest and during bolus application with different adjustments of the band.

Methods: 25 patients (mean age 38.

Background: Gallstone ileus is a rare disease and accounts for about 1-3% of mechanic ileus of the small bowel, but for 25% of all small bowel obstructions in patients older than 65 years. Concomitant cardiorespiratory diseases or diabetes are frequent in older patients and responsible for the high mortality rate. The aim of the present study was to evaluate and discuss different surgical approaches and to analyze the clinical outcome.

Background: We report the experience of a single institution with the minimally invasive resection of mediastinal masses using the da Vinci robotic surgical system.

Methods: From August 2001 to June 2003, 14 patients (5 men and 9 women aged from 21 to 77 years) with mediastinal masses were operated on minimally invasively with the da Vinci robotic system. This consisted of 9 thymectomies (6 thymomas, 2 nonatrophic thymic glands, 1 thymic cyst), 3 resections of paravertebral neurinomas, 1 ectopic mediastinal parathyroidectomy, and 1 resection of a lymphangioma.

Background: Obesity is an important risk factor for perioperative complications including the development of ventral hernias.

Methods: This retrospective study comprises patients who underwent abdominal hernia repair simultaneously with or following implantation of a Swedish Adjustable Gastric Band(R) (SAGB).

Results: 9 out of 415 patients (2.

Background: Individual band-filling on demand of the morbidly obese patient is a major advantage of adjustable gastric banding. An increasing number of patients results in an enormous amount of outpatient follow-up visits, which inspired us to compare a stepwise band-filling strategy with a single bolus injection 4 weeks after the operative procedure.

Methods: 40 consecutive patients were prospectively randomized in 2 groups.

Background: This paper reports the outcome of surgical revision for complications following laparoscopic placement of an adjustable silicone gastric band (AGB) to treat morbid obesity.

Methods: Seventy-three (19.1 per cent) of 382 patients who underwent laparoscopic AGB placement between January 1996 and March 2001 presented with complications within 6 years after operation.

Background: Laparoscopic silicone adjustable gastric banding (SAGB) has gained popularity for the surgical treatment of morbid obesity. The implantable gastric stimulator (IGS) system represents a novel surgical alternative. We aimed to assess the feasibility of robotic-assisted laparoscopic bariatric operations and to critically elucidate the technical and financial advantages and patient outcome.

Massive bleeding from an appendiceal stump is a rare but occasionally seen severe complication. The bleeding may drain into the abdominal cavity, the retroperitoneum, or the digestive tract. Gastrointestinal hemorrhage may occur early or even years after appendectomy.

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.

Background: The advantages of laparoscopy over open surgery are well known. The aim of this study was to compare our results with Swedish adjustable gastric banding (SAGB) with other laparoscopically performed bariatric procedures (gastric bypass, LapBand, vertical banded gastroplasty).

Methods: Between January 1996 and December 2001, 454 patients (381 women, 73 men) underwent laparoscopic SAGB.

Hypothesis: Preoperative chemoradiation for patients with stage II and III midrectal and low rectal cancer may improve survival and decrease local recurrence rate. We evaluated the long-term impact of neoadjuvant chemoradiation on anal sphincter function.

Design: Prospective analysis.

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: Early or late pouch dilatations account for a moderate complication rate after restrictive bariatric operations. Various strategies were developed to prevent or treat pouch dilatations.

Methods: A case of necrosis of gastric wall in a concentric dilated pouch following laparoscopic adjustable gastric banding is reported as a severe complication of a conservative treatment attempt.
