Quality-of-life outcomes with laparoscopic vs open cholecystectomy.

BACKGROUND: Few studies have assessed the health outcomes of patients who underwent cholecystectomy. The goal of this study was to evaluate the health-related quality-of-life (HRQoL) improvement of patients undergoing laparoscopic versus open cholecystectomy. METHODS: A prospective observational study was performed of consecutive patients on waiting lists to undergo cholecystectomy for nonmalignant disease in six hospitals. Patients were asked to complete two questionnaires that measure (HRQoL)-the SF-36 and the Gastrointestinal Quality of Life Index (GIQLI)-before the intervention and 3 months later. RESULTS: Improvement after surgery, measured by the SF-36 and GIQLI, was similar for both surgical techniques. The SF-health transition item showed a perception of worse health, compared to 1 year previously, for those who underwent open surgery and complications were also higher. CONCLUSIONS: HRQoL improvement at 3 months was relevant and similar for both surgical techniques, although the health transition perception was worse for those who underwent open surgery.

Predictors of improvement in health-related quality of life in patients undergoing cholecystectomy.

BACKGROUND: Few studies have assessed health-related quality of life (HRQoL) among patients undergoing cholecystectomy. This study aimed to determine clinical variables that predict changes in HRQoL following cholecystectomy. METHODS: This was a prospective study of consecutive patients undergoing elective cholecystectomy for gallstones in six hospitals. Patients were asked to complete two questionnaires-the Short Form 36 (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI)-before and 3 months after cholecystectomy. Multivariate linear regression models were used to examine factors potentially contributing to changes in HRQoL. RESULTS: Patients with symptomatic cholelithiasis and low surgical risk experienced the highest HRQoL gains in several SF-36 and GIQLI domains, with significant improvements in physical function detected by both instruments, compared with asymptomatic individuals at high surgical risk. Patients with asymptomatic cholelithiasis or high surgical risk experienced least improvement. CONCLUSION: These data indicate that cholecystectomy is appropriate for patients with symptomatic cholelithiasis and low surgical risk. In terms of HRQoL, the risk to benefit ratio seems poor for patients with asymptomatic gallstones.

Development of explicit criteria for cholecystectomy.

OBJECTIVE: Consensus development techniques were used in the late 1980s to create explicit criteria for the appropriateness of cholecystectomy. New diagnostic and treatment techniques have been developed in the last decade, so an updated appropriateness of indications tool was developed for cholecystectomy in patients with non-malignant diseases. The validity and reliability of panel results using this tool were tested. METHODS: Criteria were developed using a modified Delphi panel judgement process. The level of agreement between the panelists (six gastroenterologists and six surgeons) was analysed and the ratings were compared with those of a second different panel using weighted kappa statistics. RESULTS: The results of the main panel were presented as a decision tree. Of the 210 scenarios evaluated by the main panel in the second round, 51% were found appropriate, 26% uncertain, and 23% inappropriate. Agreement was achieved in 54% of the scenarios and disagreement in 3%. Although the gastroenterologists tended to score fewer scenarios as appropriate, as a group they did not differ from the surgeons. Comparison of the ratings of the main panel with those of a second panel resulted in a weighted kappa statistic of 0.75. CONCLUSIONS: The parameters tested showed acceptable validity and reliability results for an evaluation tool. These results support the use of this algorithm as a screening tool for assessing the appropriateness of cholecystectomy.

Translation and validation of the gastrointestinal Quality of Life Index (GIQLI).

OBJECTIVE: To translate into Spanish and validate the GIQLI, a health related quality of life questionnaire for gastrointestinal diseases. PATIENTS AND METHODS: All patients with a diagnosis of cholelithiasis, on waiting list to undergo a cholecystectomy, from three public hospitals, were included in this study. All patients were requested to fulfill the GIQLI and the SF-36 before and three months after the intervention. The validity, reliability and responsiveness of the GIQLI were studied. RESULTS: 353 patients completed both questionnaires before and after the intervention. The GIQLI was able to discriminate among levels of severity, measured by the number of previous biliary colics, between those with less (total GIQLI score: 102.7) or more than 6 colics (89.2). GIQLI domains correlated with those of the SF-36 (Pearson correlation coefficient from 0.58 to 0.79). Internal consistency of its domains was good (Cronbach alpha from 0.70 to 0.86). Responsiveness, measured by the standardized response mean, of the GIQLI ranged between 0.45 to 0.82, better than the generic questionnaire SF-36 (0.20 a 0.56). CONCLUSIONS: GIQLI translation into Spanish provides with a new tool to measure quality of life on gastrointestinal diseases. Our results support the validity, reliability and responsiveness of the GIQLI Spanish version.

Magnetic resonance study of the pancreatic duct.

AIM: to prospectively determine the diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) in the evaluation of the normal and diseased pancreatic duct. METHODS: patients seen during a 6-month period with a diagnosis of biliary tract or pancreatic disease underwent endoscopic retrograde cholangiopancreatography (ERCP) after a previous MRCP. The pancreatic duct was evaluated with both techniques in 37 patients. RESULTS: the pancreatic duct appeared normal in ERCP in 27 patients, and also appeared normal in MRCP in 25 of these patients (specificity 93%). ERCP showed moderate-severe pancreatic duct dilation in 8 patients, in whom the same diagnosis was reached with MRCP (sensitivity 100%). The causes of dilation were chronic pancreatitis (2 patients), pancreatic cancer (3 patients) and ampullary tumor (2 patients); in 1 patient the findings with both techniques were suggestive of neoplasm of the head of the pancreas or focal chronic pancreatitis. Pancreas divisum was diagnosed in 2 patients by both methods, and the predominant dorsal duct as well as the ventral duct were visualized by MRCP. CONCLUSIONS: MRCP is an accurate technique for evaluating the normal or diseased pancreatic duct, and for determining the underlying disease.

[Percutaneous endoscopic feeding gastrostomy. Initial experience with 6 cases].

Over the past two years we have performed percutaneous endoscopic feeding gastrostomy (PEFG) in 5 patients, 4 males and 1 female, aged 42 to 89. All of them suffered from either incurable or severe illness which prevented their oral feeding. PEFG was performed following the method described by Gauderer and Ponsky or traction method. Only in one case it was difficult to perform and in another case a second PEFG was needed because of unintentional catheter extraction. PEFG allowed an adequate feeding in all of the patients until their death due to underlying disorder or to other causes during the follow-up period. The complications found included ascites infection in a patient with cirrhosis and pneumoperitoneum which resolved spontaneously in another case. No mortality was observed related to the procedure.

[Response to recombinant DNA antihepatitis B vaccine in mentally retarded patients with Down's syndrome. A controlled study].

To investigate the response of mentally retarded individuals (MR) with Down's syndrome (Down-MR) to recombinant hepatitis B vaccine, three doses (20 micrograms per dose) were administered on the usual schedule (months 0, 1 and 6) to two groups of MR with mean age of 14.6 years. The first group consisted of 32 MR-Down. The second group consisted of 35 MR other etiologies (non Down-MR). Both had the same sex distribution and similar ages and weight/height index. The post vaccination anti-HBs titers were measured on months 1, 2, 6 and 8. The results could be analysed in 63 MR. Eight months after vaccination, 100% of Down-MR and 91% of non Down-MR developed a response to the vaccine (anti-HBs greater than 10 IU/l). Both groups achieved high antibody titers (geometric mean 4.298 and 6.424, respectively). A significant inverse correlation of anti-HBs with age was found, but not with sex of with the weight-height index. It was concluded that Down-MR in young age have a normal response to recombinant hepatitis B vaccine at the usual dose and schedule. Therefore, the goal to suppress the reservoir of hepatitis B in Down-MR both in institutions for MR and in normal schools should be achieved.

[Hyperplastic gastropathy with acid hypersecretion. A case report].

The case of a 60-year-old male patient with hyperplastic hypersecretory gastropathy. The diagnosis was reached by means of the histologic study of a sample obtained by endoscopic macrobiopsy. Examination of the gastric secretions showed stimulate and basal hypersecretion; gastrinemia was normal and albumin levels were at the lower limit. Several observations are made concerning the acid secretion clinical aspects and treatment of this rare disorder.
