Identifying patients at risk for high-grade intra-abdominal hypertension following trauma laparotomy

427 Background: Penile preserving surgery for penile cancer is associated with a higher risk of local recurrence (LR). This study developed a predictive model for LR following glansectomy and split skin graft reconstruction . Methods: Retrospective review performed of 177 patients undergoing glansectomy over a 10 year period. The clinicopathological features, LR patterns and cancer-specific survival (CSS) were recorded. Univariate and multivariate logistic regression was used to identify prognostic indicators for LR. The hazard ratio (HR) for LR was estimated using a KM analysis and based on these data we designed a postoperative model for the prediction of LR. Results: The median follow-up period following surgery was 41.4 (1.9-155) months. In total, 9.3 % of the patients developed a LR. Univariate, but not multivariate logistic regression identified perineural invasion (PNI), carcinoma in situ and high grade disease, but not basaloid variant, T stage, lymphovascular invasion and positive resection margins on the specimen to be predictors of LR. A risk model was designed using PNI, CIS and high grade disease in the resected specimen. KM analysis and log rank test revealed no significant differences in LR-free survival between patients with 0 vs 1 or 2 vs 3 risk factors whereas the chance of having local recurrence with 2 risk factors was significantly higher (HR = 5,75; 95% CI 1,43 to 23,15) than with 1 risk factor. A risk stratification model based on a cut-off score of > 1 out of 3 risk factors discriminated well between patients with a high vs low chance of recurrence in a Kaplan-Meier analysis (HR 9.18, 95% CI 3.29 to 25.65 P < 0.001). Indeed, ROC-curve analysis showed an optimal cut-off point of > 1 risk factors with an AUC of 0.77 (P < 0.001, specificity 63%, specificity of 85%) for prediction of LR. Conclusions: Although,LR after glansectomy does not affect the CSS, patients at risk of local recurrence can be identified when > 1 of the factors PNI, CIS and high grade are found on histopathological analysis of the glans. These findings can define the frequency of follow-up and -if validated on pre-op biopsy- potentially be helpful in planning the margins of surgical resection in patients with penile SCC.

Abstract Background Roux-en-Y gastric bypass (RYGB) is the favored bariatric option in patients with gastroesophageal reflux and Barrett’s esophagus because it prevents reflux. Weight loss and decreased reflux following RYGB could theoretically minimize the risk of progression to cancer. We aimed to demonstrate the management of high grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) developing in patients after RYGB. Methods A prospectively maintained database was searched to identify cases of HGD and cancer in RYGB patients. Charts were reviewed for past history, endoscopic findings, endoscopic therapy, and pathology findings. Results There were five cases where HGD/EAC developed several years after RYGB. The prior bariatric surgery precluded curative esophagectomy, illustrating the management challenges. All but one of the patients were uniquely and successfully managed with endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). Conclusions RYGB patients are still at risk of developing esophageal cancer. Patients at risk should be screened prior to RYGB and those with Barret’s esophagus need to undergo rigorous endoscopic surveillance following surgery. If detected early, EMR and ESD are invaluable in managing those who progress.
