Title:Cholecystectomy and sphincterotomy in patients with mild acute biliary
pancreatitis in Sweden 1988 - 2003: a nationwide register study
Version: 1Date:23 November 2008
Reviewer: Raffaele Pezzilli
Reviewer's report:
Overview
The authors report the effect of cholecystectomy/sphincterotomy within 30 days
of index admission, on readmission rate, total cholecystectomy rate at one year,
and mortality at 90 days in the Swedish population. The data were extracted from
nationwide hospital discharge and death certificate register. The conclusions are
that after an attack of mild acute biliary pancreatitis, 55% of patients in this audit
had cholecystectomy within one year of index admission but only 20% within one
month. Cholecystectomy during index stay slightly prolonged this stay, but
drastically reduced readmissions for biliary indications. The data are similar to
those already reported in other European and American countries and they do
not add any useful information on this topic.
Major compulsory resision
The main criticism of this study has been underlined by the same authors: even if
the authors have used nation-wide and validated register data based upon
personal identification numbers unique for each citizen, which makes it possible
to follow individuals over time and to record diagnoses and procedures during
each hospital stay they have limited information on patients’ clinical status. They
are not able to apply the Atlanta severity classification method to assess the mild
acute biliary pancretitis: this represents a bias for a study like this that would
assess the effect of cholecystectomy on mild acute biliary pancreatitis.
Discretionary revisions
1. In the results section the authors should report the mean age and the
respective range of the patients studied (see Table 1).
2. The four different MBAP groups studied should be reported in the methods
section
Level of interest: An article of limited interest
Quality of written English: Not suitable for publication unless extensively edited
Statistical review: Yes, and I have assessed the statistics in my report.
