Frame stability in Ilizarov external fixators is mainly dependent on the tension of the transosseous wires, which are clamped to the ring by connection bolts. It was the purpose of this biomechanical study to investigate the holding capacity of a modified bolt design featuring a ruffled wire-bolt interface (TrueLok™) and its influence on wire stiffness in comparison with that of classic bolts f...

Current practice and future perspectives in surgery for rectal prolapse Chapter 2 Evaluation and surgical treatment of rectal prolapse: An international survey. 19 Chapter 3 Laparoscopic ventral rectopexy for rectal prolapse and symptomatic rectocele: an analysis of 245 consecutive patients. 43 Chapter 5 Laparoscopic resection rectopexy versus laparoscopic ventral rectopexy for complete rectal ...

BACKGROUND The influence of rectal contractions on urination was examined using multichannel urodynamic study. METHODS We reviewed a total of 246 consecutive urodynamic studies. Each study consisted of a uroflow measurement and multi-channel urodynamic study, evaluating total vesical pressure, abdominal (rectal) pressure, subtracted detrusor pressure and perianal electromyography. Rectal cont...

through the anal canal. Precisely how a complete rectal prolapse develops is not thoroughly understood. Possible etiologies include a defect of the pelvic floor, redundant rectosigmoid colon, deep Douglas pouch, gender (female), psychiatric problems and nulliparity. Pathogenesis may involve a sliding hernia or a circumferential intussusception. Treatment of rectal prolapse can involve a variety...

Observations support the theory that development of left- and right-sided colorectal cancers may involve different mechanisms. This study investigated different genes involved in oncogenesis of colon and rectal cancers and analysed their prognostic value. The study group comprised 35 colon and 42 rectal cancers. Rectal cancer patients had been treated with standardized surgery performed by an e...

Rectal prolapse is a distressing condition associated with incontinence. However, incarcerated rectal prolapse is a rather rare entity. We had a 75-year-old man with irreducible rectal prolapse who required recto-perineal sigmoidectomy (Altemeier’s procedure) after failure of initial conservative treatment. Histology showed rectal tubulo villous adenoma with moderate to severe dysplasia. This c...

The aim of this study is to present the technique and outcome of the management of a newborn child with rectal atresia. A girl born with rectal atresia was diagnosed during physical examination and confirmed with X-ray. The anatomic appearance of the external anus, and lower pelvis was normal. The rectal ending was located 2 cm cranial from the anus and the distance between the rectal endings w...

BACKGROUND The implementation of preoperative chemoradiation combined with total mesorectal excision has reduced local recurrence rates in rectal cancer. However, the use of both types of treatment in upper rectal cancer is controversial. OBJECTIVE The purpose of this work was to assess oncological results after radical resection of upper rectal cancers compared with sigmoid, middle, and lowe...

BACKGROUND Rectal cancer patients that show a pathological complete response (pCR) after neo-adjuvant chemo-radiotherapy, have better prognosis. To increase pCR rates several studies escalate the tumor irradiation dose. However, due to lacking tumor contrast on online imaging techniques, no direct tumor setup can be performed and large boost margins are needed to ensure tumor coverage. The purp...

BACKGROUND AND AIMS Although external anal sphincter dysfunction is the major cause of urge faecal incontinence, approximately 50% of such patients have evidence of rectal hypersensitivity and report exaggerated stool frequency and urgency. The contribution of rectosigmoid contractile activity to the pathophysiology of this condition is unclear, and thus the relations between symptoms, rectal s...
