The present study examined the psychometric characteristics of a “core-set” of six individual questions (on pain, function, symptom-specific well-being, work disability, social disability and satisfaction) for use in low back pain (LBP) outcome assessment. A questionnaire booklet was administered to 277 German-speaking LBP patients with a range of common(More)
Work and activity-specific fear-avoidance beliefs have been identified as important predictor variables in relation to the development of, and treatment outcome for, chronic low back pain. The objective of this study was to provide a cross-cultural German adaptation of the Fear-Avoidance Beliefs Questionnaire (FABQ) and to investigate its psychometric(More)
BACKGROUND Patient-oriented questionnaires are indispensable in the assessment of surgical outcome. The psychometric properties of a brief multidimensional instrument were examined in patients with inguinal hernia undergoing surgery. METHODS Fifty-one patients (mean(s.d.) age 50·6(17·4) years; 48 men) participated. The following questionnaire properties(More)
We report a rare case of synchronous bilateral and multifocal ductal carcinoma in situ (DCIS) in a 30-year-old patient operated on for gynecomastia following repeated injections of stanozolol, a non-aromatizable androgen. The familial medical history was negative for breast cancer and work-up of serum hormone levels was normal. The patient underwent a(More)
OBJECTIVE The aim of the present study was to investigate the outcomes of different treatment options for acute and chronic pilonidal disease in a single large cohort of patients. MATERIALS AND METHODS Four hundred and twenty-one consecutive patients (171 with chronic disease and 250 with acute abscess formation) who underwent surgery between 2003 and(More)
INTRODUCTION Long-term outcome data after total endoscopic preperitoneal hernia repair are scarce. This study reports the 10-year results after endoscopic total extraperitoneal hernia repair in terms of recurrence rates and various patient-orientated indicators of quality of life. METHODS Between July 1995 and April 2000, 107 consecutive patients(More)
BACKGROUND Tumors arising in the neck and body of the pancreas often invade the common hepatic artery and celiac axis (CA), necessitating distal pancreatectomy, splenectomy, and celiac axis resection (DPS-CAR). In these patients, the need for revascularization of the common hepatic artery (CHA) can be avoided on the basis of the pressure change in the CHA(More)
The variables identified as predictors of surgical outcome often differ depending on the specific outcome variable chosen to designate “success”. A short set of multidimensional core outcome measures was recently developed, in which each of the following domains was addressed with a single question and then combined in an index: pain, function,(More)
BACKGROUND Resection of the involved mesenteric-portal vein (MPV) is increasingly performed in pancreatoduodenectomy. The primary aim of this study is to assess the rate of R0 resection in transverse closure (TC) versus segmental resection with end-to-end (EE) closure and the secondary aims are to assess the short-term morbidity and long-term survival of TC(More)
BACKGROUND In the literature, there is a wide range of reported morbidity and mortality rates after acute paraesophageal hernia (PH) repair. MATERIALS AND METHODS Data were collected from all patients undergoing PH repair between December 2001 and October 2011. Outcome data were compared between the acute and elective groups. RESULTS Over the study(More)
