Flexible endoscopy is enough diagnostic prior to loop ileostomy reversal.

PURPOSE: This study investigates whether contrast enema (CE) and flexible endoscopy (FE) should be performed routinely after low anterior resection (LAR) before ileostomy reversal. Additionally, the impact of previous anastomotic leakage (AL) on diagnostic test accuracy (DTA) was assessed. METHODS: This is a retrospective analysis of prospectively collected tertiary care data of two centers. Consecutive rectal cancer patients undergoing LAR with loop ileostomy formation were included. Before ileostomy reversal, all patients were assessed by CE and FE. DTA of FE and CE for asymptomatic AL in patients who had previously suffered from clinically relevant AL (group 1) compared with those without apparent AL after LAR (group 0) were assessed separately. RESULTS: Two hundred ninety-three patients were included in the analysis, 86 in group 1 and 207 in group 0. Overall sensitivity for detection of asymptomatic AL was 76% (FE) and 60% (CE). Specificity was 100% for both tests. DTA of FE was equal or superior to CE in all subgroups. Prevalence of asymptomatic AL at the time of testing was 1.4% in group 0 and 25.6% in group 1. CONCLUSION: Flexible endoscopy is the more accurate diagnostic test for the detection of asymptomatic anastomotic leaks prior to ileostomy reversal. Contrast enema showed no gain of information. In the group without complications after the initial rectal resection, 104 must be tested to find one leak prior to reversal. In those patients, routine diagnostic testing additional to digital rectal examination may be questioned.

[Quality of documentation of intraoperative and postoperative complications : improvement of documentation for a nationwide quality assurance program and comparison with routine data]. / Dokumentationsqualität intra- und postoperativer Komplikationen : Verbesserung der Dokumentation für die verpflichtende Qualitätssicherung und Vergleich mit DRG-Routinedaten.

INTRODUCTION: Complications after cholecystectomy are continuously documented in a nationwide database in Germany. Recent studies demonstrated a lack of reliability of these data. The aim of the study was to evaluate the impact of a control algorithm on documentation quality and the use of routine diagnosis coding as an additional validation instrument. METHODS: Completeness and correctness of the documentation of complications after cholecystectomy was compared over a time interval of 12 months before and after implementation of an algorithm for faster and more accurate documentation. Furthermore, the coding of all diagnoses was screened to identify intraoperative and postoperative complications. RESULTS AND DISCUSSION: The sensitivity of the documentation for complications improved from 46 % to 70 % (p = 0.05, specificity 98 % in both time intervals). A prolonged time interval of more than 6 weeks between patient discharge and documentation was associated with inferior data quality (incorrect documentation in 1.5 % versus 15 %, p < 0.05). The rate of case documentation within the 6 weeks after hospital discharge was clearly improved after implementation of the control algorithm. Sensitivity and specificity of screening for complications by evaluating routine diagnoses coding were 70 % and 85 %, respectively. The quality of documentation was improved by implementation of a simple memory algorithm.

Intensified neoadjuvant chemoradiotherapy in locally advanced rectal cancer -- impact on long-term quality of life.

AIMS: In spite of advances in rectal cancer surgery and the use of preoperative 5-fluorouracil-(5-FU) based chemoradiotherapy (CRT) in stage II and III disease distant metastases still occur in about 35-40% of the patients. Intensified preoperative CRT (ICRT) using other drugs in conjunction with 5-FU has been investigated in order to improve the pathological complete remission (pCR) rate and thereby prognosis of patients with locally advanced rectal cancer. However, acute toxicity, especially diarrhea, was reported to be high and no improvement in pCR rates has been observed in randomized trials. Long-term results of these trials are pending. In the present analysis we investigated the impact of ICRT on health related quality of life and long term toxicity. METHODS: The present study included 119 patients with locally advanced rectal cancer who underwent neoadjuvant CRT followed by surgery within controlled clinical trials. Patients received ICRT (n = 83) or standard CRT (n = 36). Evaluation of HRQoL was performed using EORTC QLQ-C30 and QLQ-CR29 questionnaires. RESULTS: The overall rating of global health status/QLQ scale of the EORTC QLQ-C30 questionnaire was identical in both patient groups but patients in the CRT group showed better results in four out of nine function scales. Concerning symptom scales, patients in the CRT arm exhibited significantly less diarrhea (p = 0.028) and less disorders with taste (0.042). CONCLUSIONS: This data suggests that higher gastrointestinal acute toxicity caused by ICRT might lead to a higher risk of long-term deterioration of "gastrointestinal QoL". Future results of randomized trials investigating ICRT versus CRT should be discussed in the light of long-term QoL data.

[Passive electrostimulation therapy of the anal sphincter is inferior to active biofeedback training]. / Die passive Elektrostimulationstherapie des Analsphinkters ist dem aktiven Biofeedbacktraining unterlegen.

Anal incontinence can be treated by conservative therapy if a significant anatomical sphincter defect has been excluded. We compared electrostimulation therapy with biofeedback training in a prospective study. Results showed that up to two thirds of all patients can be treated successfully, whereby the results of biofeedback were better than those of electrostimulation.
