We conclude that the high rate of recurrence and intervention in the nonoperative group and the high proportion of these patients who did not receive adequate follow-up despite the relatively high rate (5.9%) of bowel malignancy support the operative management of an appendiceal inflammatory mass. Noninterventional management or a percutaneous intervention should be reserved as a bridge to surgery for patients with a large accompanying abscess or as treatment for patients with significant comorbidity. If nonoperative treatment is chosen, follow-up colonoscopy is mandatory to exclude malignancy.
BACKGROUND: Patients with a locally advanced rectal carcinoma benefit from preoperative chemoradiotherapy. MRI is considered the first choice imaging modality after preoperative chemoradiation, although its reliability for restaging is debatable. OBJECTIVE: The purpose of this study was to determine the accuracy of MRI in restaging locally advanced rectal cancer after preoperative chemoradiation. DESIGN: This was a retrospective study. SETTINGS: The study was conducted in a Dutch high-volume rectal cancer center. PATIENTS: A consecutive cohort of 48 patients with locally advanced rectal cancer treated with a curative intent was identified. MAIN OUTCOME MEASURES: Three readers independently evaluated the MRI both for primary staging and for restaging after preoperative chemoradiation and were blinded to results from the other readers as well as histological results. Interobserver variability was determined. Accuracy of the restaging MRI was assessed through the comparison of tumor characteristics on MRI with histopathologic outcomes. RESULTS: T stage was correctly predicted by the 3 readers in 47% to 68% and N stage in 68% to 70%. Overstaging was more common than understaging. Positive predictive values (PPV) among the 3 readers for T0 were 0%, and negative predictive values (NPVs) varied from 84% to 85%. For T1/2, PPVs and NPVs were 50% to 67% and 72% to 90%, and for T3/4 they were 54% to 62% and 33% to 78%. PPVs and NPVs for N0 stage were 81% to 95% and 58% to 73%. Tumor regression grade on MRI did not correspond with histopathologic tumor regression grade; PPVs for good response (tumor regression grade on MRI 1–2) were 48% to 61%, and NPVs were 42% to 58%. Interobserver agreement was fair to moderate for T stage, N stage, and tumor response (κ = 0.20–0.41) and fair to substantial for the relation with the mesorectal fascia (κ = 0.33–0.77). In none of the patients was the surgical plan changed after the restaging MRI. LIMITATIONS: This study was limited by its small sample size and retrospective nature. CONCLUSIONS: MRI has low accuracy for restaging locally advanced rectal cancer after preoperative chemoradiation, and the interobserver variability is significant.
Aim The Enhanced Recovery After Surgery (ERAS) programme is a multimodal approach to improve peri--operative care in colon surgery. The aim of this study was to report on the adherence to and outcomes of ERAS in the first years after implementation. Multivariate analysis showed that age, laparoscopic surgery, removal of nasogastric tube before extubation, mobilization within 24 h after surgery, starting nonsteroidal anti-inflammatory drugs at day 1 and removal of thoracic epidural analgesia at day 2 were independent predictors of LOS. MethodConclusion Strict adherence to the ERAS protocol was associated with reduced LOS and improved outcome in elective colon surgery for malignancy. These benefits were lost when protocol adherence was lower. Embedding the ERAS protocol into an organization and repetitive education are vital to sustain its beneficial effects on LOS and outcome.
Background Routine colonoscopy was traditionally recommended after acute diverticulitis to exclude coexistent malignancy. Improved CT imaging may make routine colonoscopy less required over time but most guidelines still recommend it. The aim of this review was to assess the role of colonoscopy in patients with CT‐proven acute diverticulitis. Methods PubMed and Embase were searched for studies reporting the prevalence of advanced colorectal neoplasia (ACN) or colorectal carcinoma in patients who underwent colonoscopy within 1 year after CT‐proven left‐sided acute diverticulitis. The prevalence was pooled using a random‐effects model and, if possible, compared with that among asymptomatic controls. Results Seventeen studies with 3296 patients were included. The pooled prevalence of ACN was 6·9 (95 per cent c.i. 5·0 to 9·4) per cent and that of colorectal carcinoma was 2·1 (1·5 to 3·1) per cent. Only two studies reported a comparison with asymptomatic controls, showing comparable risks (risk ratio 1·80, 95 per cent c.i. 0·66 to 4·96). In subgroup analysis of patients with uncomplicated acute diverticulitis, the prevalence of colorectal carcinoma was only 0·5 (0·2 to 1·2) per cent. Conclusion Routine colonoscopy may be omitted in patients with uncomplicated diverticulitis if CT imaging is otherwise clear. Patients with complicated disease or ongoing symptoms should undergo colonoscopy.
