Long term results after stapled anopexy for symptomatic haemorrhoidal prolapse

The prevalence of hemorrhoids in adults

INTRODUCTION

Exact data on the prevalence of hemorrhoids are rare. Therefore, we designed a study to investigate the prevalence of hemorrhoids and associated risk factors in an adult general population.

METHODS

Between 2008 and 2009, consecutive patients were included in a prospective study. They attended the Austrian national wide health care program for colorectal cancer screening at four medical institutions. A flexible colonoscopy and detailed examination were conducted in all patients. Hemorrhoids were defined according to a standardized grading system. Independent variables included baseline characteristics, sociodemographic data, and health status. Potential risk factors were calculated by univariate and multivariate analysis.

RESULTS

Of 976 participants, 380 patients (38.93%) suffered from hemorrhoids. In 277 patients (72.89%), hemorrhoids were classified as grade I, in 70 patients (18.42%) as grade II, in 31 patients (8.16%) as grade III, and in 2 patients (0.53%) as grade IV. One hundred seventy patients (44.74%) complained about symptoms associated with hemorrhoids, whereas 210 patients (55.26%) reported no symptoms. In the univariate and multivariate analysis, body mass index (BMI) had a significant effect on the occurrence of hemorrhoids with p = 0.0391 and p = 0.0282, respectively. Even when correcting for other potential risk factors, an increase in the BMI of one increased the risk of hemorrhoids by 3.5%.

CONCLUSION

Hemorrhoids occur frequently in the adult general population. Notably, a considerable number of people with hemorrhoids do not complain about symptoms. In addition, a high BMI can be regarded as an independent risk factor for hemorrhoids.

Haemorrhoids and quality of life

AIM

There are few studies into the quality of life of patients with haemorrhoids. The aim of this study was to assess the quality of life of patients with haemorrhoids in an adult general population.

METHOD

Participants, who attended the Austrian nationwide healthcare programme for colorectal cancer screening at four medical institutions, were enrolled prospectively between 2008 and 2009. A colonoscopy was performed in all patients. Haemorrhoids were classified according to an international grading system and defined as symptomatic in cases with bleeding, itching, soiling or pain. Quality of life was measured by the Short Form-12 Health Survey.

RESULTS

Of 976 participants, 380 patients (39%) had haemorrhoids. The median physical health score was 52.6 (range 20.6-61.3) in the symptomatic and 53.2 (range 16.2-61.3) in the asymptomatic group (P = 0.7993). The median mental health score showed also no significant difference between both groups [symptomatic group, 52.8 (range 12.4-62.6); asymptomatic group, 54.8 (range 18.7-67.2); P = 0.0738].

CONCLUSION

Haemorrhoids, irrespective of their degree, do not influence quality of life measured by the Short Form-12 Health Survey.
