Introduction: In the literature, data on the effects of gender and age on the pressure data of anorectal manometry differ. Possible reasons are investigation of only small numbers of healthy people and comparison of only 2 groups with large age differences. In addition, data about the influence of gender or age on anorectal sensation are sparse. Therefore, the aim of the present study was to determine the influence of gender and age on anorectal manometry in a large healthy female and male cohort spanning a great age range. Methods: Anorectal manometry was performed in 72 women and 74 men with a median age of 64 years in both groups (ranges: women 22–90 years; men 23–88 years). We determined mean anal resting and squeeze pressure as well as minimal rectal balloon volume for perception and for urge/desire to defecate. The Mann-Whitney U test was used to analyze for gender differences, regression analysis to search for age influences. Results: Squeeze pressure (p = 0.007) and perception threshold (p < 0.001) are significantly lower in females, while the mean resting pressure and urge threshold are similar in females and males. Mean resting pressure (women p < 0.0001; men p = 0.03) and mean squeeze pressure decrease (women p < 0.0001; men p = 0.004) with age. An age-related increase in sensory thresholds (= decreased rectal sensitivity) is only seen in females (perception threshold p = 0.01; urge threshold p = 0.04). Conclusion: Most of the parameters measured by anorectal manometry (anal canal pressure, sensory thresholds) are influenced by gender and age. Therefore, the results of anorectal manometry must be interpreted in relation to sex- and age-adapted normal values.

ZusammenfassungDie Leitlinie Komplikationen der Leberzirrhose der Deutschen Gesellschaft für Gastroenterologie, Verdauungs- und Stoffwechselkrankheiten (DGVS) ersetzt die Leitlinie aus dem Jahr 2011. Sie basiert auf den Empfehlungen der Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF) für eine evidenzbasierte Konsensus-Leitlinie der Entwicklungsstufe S2k und wurde interdisziplinär unter Beteiligung aller relevanten Fachgesellschaften und der Patientenvertretung erstellt. Neben den in der Vorgängerversion behandelten Kapiteln Aszites, spontan bakterielle Peritonitis, hepatorenales Syndrom, hepatischer Hydrothorax und hepatopulmonales Syndrom wurden die Kapitel Diagnostik und Therapie der Hepatischen Enzephalopathie neu aufgenommen.

Damage control strategy in patients with generalized peritonitis due to perforated diverticulitis leads to a significantly reduced stoma rate after the initial hospital stay without an increased risk of postoperative morbidity.
