[Anti-reflux surgery in Norway].

BACKGROUND: The aim of this study was to investigate the incidence of gastro-oesophageal antireflux surgery in Norway from 1999 to 2003, in comparison with the 1990 to 1998 period. MATERIAL AND METHODS: Operation codes for laparoscopic and open antireflux surgery were compiled from the Norwegian Patient Registry for analysis of incidence rates, geographic variations, postoperative hospital stay and rates of readmission. RESULTS: The incidence rates of antireflux operation in 1999-2003 were 18.6 per 100,000 men and 10.2 per 100,000 women, a ten-fold increase compared to 1990. There were significant differences in operation rates between the five Norwegian health regions, highest in northern region. In 1999, 85% of the patients had a laparoscopic operation, compared with 89% in 2003. Postoperative hospital stay was significantly shorter after laparoscopic operations. The proportion of laparoscopic procedures varied between the regions (78%-93%). The total rate of readmission within 60 days was 7%. There was no significant difference between readmission rates for patients treated by laparoscopy (6%) compared to patients treated by laparotomy (9%). In one health region, a high proportion of the patients were day surgery cases. CONCLUSION: The incidence of antireflux operation increased strongly during the 1990s and varies significantly between the Norwegian health regions. Laparoscopy is the leading mode of surgery. Patients treated by open surgery have a significant longer postoperative hospital stay than patients treated by laparoscopy.

[Laparoscopic cholecystectomy].

Gallbladder stones are common, but most persons with stones are asymptomatic. The symptoms of gallbladder stones are usually characteristic. They are often associated with other types of abdominal symptoms, which are not affected by cholecystectomy. Day surgery laparoscopic cholecystectomy is increasingly popular. The operation may be associated with serious complications, but the risk is low. 85-90% of patients operated with cholecystectomy are asymptomatic after the operation.

[Outpatient laparoscopic fundoplication for gastroesophageal reflux disease].

BACKGROUND: Day-case laparoscopic fundoplication for gastro-oesophageal reflux disease was introduced in January 1997. MATERIAL AND METHODS: Inclusion criteria were ASA grade 1-2, living within 30 minutes by car from the hospital, or staying over in the patient hotel the first night, with company. Initially, only selected patients were offered day-case treatment; later it was adopted as routine. The patients underwent general intravenous anaesthesia with propofol and remifentanil and were given prophylaxis against postoperative pain and nausea. The surgical procedure was Nissen-Rossetti fundoplication or semifundoplication. RESULTS: 83 patients were included. Ten patients were admitted, 73 (88%) were discharged as planned 3-8 hours after the operation. Eight patients (10%) were readmitted; one of them underwent reoperation for necrosis of the gastric fundus. Eight patients visited the outpatient department without need for readmission. At seven-day follow-up, 55 discharged patients (75%) were satisfied with the day-case treatment, nine (12%) were indifferent, and nine (12%) were dissatisfied, mostly because of pain. If offered a similar operation in the future, 50 patients (68%) would have preferred and 11 (15%) would have accepted day-case treatment; 12 (16%) would not. INTERPRETATION: Outpatient laparoscopic fundoplication is safe and well tolerated by the majority of patients.

[Laparoscopic fundoplication for gastroesophageal reflux disease].

BACKGROUND: In 1995 we introduced laparoscopic technique as routine for fundoplication for gastro-esophageal reflux disease. MATERIAL AND METHODS: 222 patients were scheduled for laparoscopic fundoplication; the operation was completed laparoscopically in 219 patients. They all had an observation period of one year as a minimum; 205 patients returned a follow-up questionnaire. RESULTS: 12 patients had major complications, six of them have been reoperated. At follow-up, 95% reported excellent or good results, 3% had persisting reflux symptoms, 4% had moderate to severe dysphagia and 17% had moderate to severe gas bloat syndrome and flatulence problems which adversely affected an otherwise good outcome. Thus, 63% reported excellent, 23% good and 7% fair outcome, and 6% were moderately or very dissatisfied. Bloating and increased flatulence were the major reasons for dissatisfaction. INTERPRETATION: The risk of troublesome postoperative bloating and flatulence should be addressed thoroughly during the preoperative information, and especially in patients who have similar symptoms preoperatively.

[Laparoscopic treatment of splenic cysts].

Splenic cysts are uncommon. The symptoms are usually vague, but complications such as haemorrhage, rupture and infection may occur. The majority of splenic cysts are seen in children and young adults. Surgical treatment is recommended and splenic preservation is advantageous. We present two patients with splenic cysts successfully treated with laparoscopic resection of the cyst wall.

[Secretin stimulated magnetic resonance cholangiopancreatography in diseases of the biliary and pancreatic ducts].

BACKGROUND: MRCP has replaced ERCP as the diagnostic tool in diseases in the biliary and pancreatic ducts. Secretin increases the secretion to ducts, and this has been reported to improve MRCP image quality. MATERIAL AND METHODS: We report our experience with S-MRCP in our first 20 patients. Secretin was given intravenously and images were obtained every minute for 10 minutes. These images were compared with MRCP images taken before and after secretin stimulation. RESULTS: New information was yielded in 18 cases, i.e. information not observed in previous radiological examinations. INTERPRETATION: In diagnostics of dysfunction of the sphincter of Oddi, the method may be useful, given the functional aspect of the procedure where increased pressure in the ducts may lead to pain. It may further improve the diagnostics of pancreatic cancer versus pancreatitis, in pancreas divisum and sclerosing cholangitis. The method is also valuable for clarifying whether there is injury to the pancreatic duct after blunt abdominal trauma. Surgical common bile duct injuries may be better assessed than with any other method. In difficult pancreatic and biliary investigations, S-MRCP seems to be a useful and complication-free supplement to existing diagnostic methods.
