[Relaparotomy in secondary peritonitis Planned relaparotomy or relaparotomy on demand?]. / Relaparotomie bei sekundärer Peritonitis. Programmierte Relaparotomie oder Relaparotomie "on demand"?

Secondary peritonitis is associated with serious morbidity and a persistent high mortality in recent decades, this despite improvement in antibiotic, intensive care and surgical treatment. The available literature regarding the surgical treatment of secondary peritonitis was searched through Pubmed (1966- January 2005) as well as a hand search of references of retrieved articles. Definitions, pathophysiology and classification of secondary peritonitis are discussed, as well as the scientific rationale for the surgical treatment in secondary peritonitis. The historical development and the scientific foundation of present-day relaparotomy strategies in secondary peritonitis are evaluated, with an emphasis on two frequently applied surgical treatment strategies: planned relaparotomy and relaparotomy on demand. Criteria for relaparotomy after the initial laparotomy and potential areas for further research to reduce both morbidity and mortality are discussed. Furthermore, the care of patients with secondary peritonitis is evolving from a surgical entity to a more multidisciplinary challenge uniting surgeons, intensivists, radiologists and microbiologists. Research needs to be expanded into novel fields to further decrease morbidity and mortality.

[Diagnostic modalities in diagnosis of adult patients with acute abdominal pain]. / Aanvullende diagnostiek bij volwassenen met acute buikpijn.

In order to provide an accurate diagnosis and management strategy for adult patients with acute abdominal pain and peritoneal irritation, it is important to understand the value of various forms of diagnostics modalities. History, physical examination and laboratory results can generally differentiate between an acutely serious and a less serious abdominal problem. Patients with acute abdominal pain and no increase in either the leukocyte count or the concentration of C-reactive protein should be re-evaluated after 12 hours. If laboratory values are increased, then diagnostic imaging is necessary. For patients with diffuse abdominal pain and for patients with signs of shock or respiratory insufficiency, a CT-scan is the imaging method of choice. If symptoms are located in the left upper quadrant, an upright chest radiograph or a plain abdominal film are recommended. If symptoms are located in the right upper quadrant, ultrasonography will be preferred. If the diagnosis is still uncertain, a CT-scan will be performed. A CT-scan is indicated for lower abdominal pain in women with increased inflammatory parameters and in men aged 50 years or older with increased inflammatory parameters. If the cause of the abdominal pain is still unclear following a CT-scan, then diagnostic laparoscopy may be considered for fertile women of childbearing age and for men aged less than 50 years with signs of appendicitis.

Meta-analysis of relaparotomy for secondary peritonitis.

BACKGROUND: Planned relaparotomy and relaparotomy on demand are two frequently employed surgical treatment strategies for patients with abdominal sepsis. METHODS: The available literature was evaluated to compare the efficacy of both surgical treatment strategies. A systematic search for studies comparing planned and on-demand relaparotomy strategies in adult patients with secondary peritonitis was employed. Studies were reviewed independently for design features, inclusion and exclusion criteria, and outcomes. The primary outcome measure was in-hospital mortality. RESULTS: No randomized studies were found; eight observational studies with a total of 1266 patients (planned relaparotomy, 286; relaparotomy on demand, 980) met the inclusion criteria and were included in the meta-analysis. These eight studies were heterogeneous on clinical and statistical grounds (chi2= 40.7, d.f. = 7, P < 0.001). Using a random-effects approach, the combined odds ratio for in-hospital mortality was 0.70 (95 per cent confidence interval 0.27 to 1.80) in favour of the on-demand strategy. CONCLUSION: The combined results of observational studies show a statistically non-significant reduction in mortality for the on-demand relaparotomy strategy compared with the planned relaparotomy strategy when corrected for heterogeneity in a random-effects model. Owing to the non-randomized nature of the studies, the limited number of patients per study, and the heterogeneity between studies, the overall evidence generated by the eight studies was inconclusive.
