Background Postoperative ileus is a common condition after abdominal surgery. Many prokinetic drugs have been evaluated including osmotic laxatives. The data on colon-stimulating laxatives are scarce. This prospective, randomized, doubleblind trial investigates the effect of the colon-stimulating laxative bisacodyl on postoperative ileus in elective colorectal resections.

The PFN is an appropriate implant in cases of per-, inter- and subtrochanteric femur fractures. Anatomical resetting and correct implant positioning are the keys to successful osteosynthesis. The risk of implant failure is highest in the case of multi-fragmentary per- and intertrochanteric fractures in which medial strengthening has been degraded in patients aged over 80 years. The clinical results in elderly patients are unsatisfactory.

Stapled hemorrhoidectomy (circumferential mucosectomy) is a technique for the surgical management of third- to fourth-degree hemorrhoids. It is a quick, simple, and painless technique. Complications are endoluminal bleeding, anal stenoses, fistulas, and incontinence. This case report deals with a severe complication which has not been described yet. Our patient had anemic, retroperitoneal bleeding with consecutive evacuation of the hematoma through the stapler anastomosis and following several operations. Nevertheless, a temporary colostomy was not necessary. As mentioned in other publications describing complications after stapled hemorrhoidectomy, this new technique should be used carefully and by surgeons with experience.

Lung disease is the direct cause of death in more than 90% of cystic fibrosis (CF) patients. Proteinase-antiproteinase imbalances are common in CF and alpha-1-antitrypsin (AAT) deficiency. We investigated the hypothesis that the AAT deficiency alleles PiS and PiZ contribute to pulmonary prognosis in CF. Two hundred and sixty-nine CF patients from Southern Germany were included in this study. The serum concentrations of AAT and C-reactive protein (CRP) were determined by nephelometry, and patients were screened by polymerase chain reaction (PCR) and restriction enzyme digest for the common AAT deficiency alleles PiS and PiZ. The onset of chronic bacterial colonization by Pseudomonas aeruginosa (Pae) was correlated with the AAT phenotypes PiMM, PiMS and PiMZ. Only three out of nine CF patients (33%) diagnosed with either PiMS or PiMZ had developed chronic Pae lung infection earlier in their lives. The remaining six patients showing a PiMS or PiMZ phenotype showed a later onset of chronic Pae lung infection. Our results indicate that PiMS and PiMZ are not associated with worse pulmonary prognosis in CF. These data need to be confirmed in studies with a much larger number of cases.
