BackgroundSynchronous colon cancers, defined as two or more primary colon cancer detected simultaneously at the time of initial diagnosis, account for up to 5% of all colon cancer diagnoses. Management principles and outcomes remain largely undefined.MethodsA retrospective institutional review of patients undergoing curative intent resection for colon adenocarcinoma (Stages I–III) from 1995 to 2007 was performed. Hereditary causes or inflammatory bowel disease were excluded. Matching was performed and Kaplan–Meier analysis was used to compare overall survival.ResultsOf 2,387 patients, 100 (4.2%) had synchronous cancers. Patients with synchronous lesions tended to be older (median 77 vs. 72 years, P < 0.001) with more advanced tumors (41.0% vs. 31.4% Stage III, P = 0.04). After matching, there were no differences in demographics or tumor factors (all P > 0.05). Compared to solitary, synchronous cancers demonstrated an inferior 10‐year overall survival (53.9% vs. 36.5%, P = 0.009). Subset analysis of patients with synchronous cancers showed no difference in overall survival between those with extended versus segmental resections at 120‐months (P = 0.07).ConclusionSynchronous colon cancer is associated with decreased overall survival compared to patients with solitary tumors. Extended resection does not confer a survival benefit in these patients. Further research is needed to determine how to mitigate the poor outcomes. J. Surg.

Abstract Background Surgical performance, provider health, and patient safety can be compromised when workload demands exceed individual capability on the surgical team. The purpose of this study is to quantify and compare intraoperative workload among surgical team members. Methods Observations were conducted for an entire surgical day for 33 participating surgeons and their surgical team at one medical institution. Workload (mental, physical, case complexity, distractions, and case difficulty) was measured for each surgical team member using questions from validated questionnaires. Statistical analyses were performed with a mixed effects model. Results A total of 192 surgical team members participated in 78 operative cases, and 344 questionnaires were collected. Procedures with high surgeon mental and physical workload included endovascular and gastric surgeries, respectively. Ratings did not differ significantly among surgeons and residents, but scrub nurses physical demand ratings were 14–22 (out of 100) points lower than the surgeons, residents, and surgical assistants. Residents reported the highest mental workload, averaging 19–24 points higher than surgical assistants, scrub nurses, and circulating nurses. Mental and physical demands exceeded 50 points 28–45 % of the time for surgeons and residents. Workload did not differ between minimally invasive and open techniques. Conclusion The workload questionnaires are an effective tool for quantifying intraoperative workload across the surgical team to ensure mental and physical demands do not exceed thresholds where performance may decrease and injury risk increase. This tool has the potential to measure the safety of current procedures and drive design of workload interventions.

Abstract Background Treatment guidelines for stage II and III rectal cancer include neoadjuvant chemoradiotherapy, surgery and postoperative adjuvant chemotherapy. Although data support this recommendation in younger patients, it is unclear whether this benefit can be extrapolated to elderly patients (aged 75 years or older). Methods This was a retrospective review of patients aged at least 75 years with stage II or III rectal cancer who underwent surgery with curative intent from 1996 to 2013 at the Mayo Clinic. Kaplan–Meier analysis and log rank test were used to compare overall survival between therapy groups. Cox proportional hazards model was used to estimate the independent effect of treatment group on survival. Results A total of 160 elderly patients (median age 80 years) with stage II (66) and stage III (94) rectal cancer underwent surgical resection. Only 30·0 and 33·8 per cent received neoadjuvant or adjuvant therapy respectively. Among patients with stage II disease, there was no significant difference in 60-month survival between patients who received any additional therapy and those who had surgery alone (55 versus 38 per cent respectively; P = 0·184), whereas additional therapy improved survival in patients with stage III tumours (58 versus 30 per cent respectively; P = 0·007). Multivariable analysis found a survival benefit for additional therapy in elderly patients with stage III disease (hazard ratio 0·58, 95 per cent c.i. 0·34 to 0·98). Conclusion A multimodal approach in elderly patients with stage III rectal cancer improved oncological outcomes.

AbstractIntroductionCurrent National Comprehensive Cancer Network guidelines for Stages II and III rectal cancer recommend neoadjuvant chemoradiation followed by curative intent surgery and adjuvant chemotherapy. It is unclear whether therapies in addition to surgery are truly beneficial in elderly patients. Our aim was to compare the survival of patients over 80 with Stages II and III rectal cancer undergoing curative intent surgery with or without additional therapy.Materials and methodsThe National Cancer Data Base (NCDB 2006–2011) was queried for patients over 80 with Stages II and III rectal cancer. The primary outcome was overall survival. Patients were stratified based upon therapy group. Univariate group comparisons were made. Unadjusted Kaplan–Meier and multivariable Cox proportional hazards modeling survival analyses were performed.ResultsThe query yielded 3098 patients over 80 with Stage II (N = 1566) or Stage III (N = 1532) disease. Approximately, half of the patients received surgery only. Kaplan–Meier analysis showed improved survival for patients receiving neoadjuvant and/or adjuvant therapy in addition to surgery, but there was no significant difference between those that received guideline concordant care (GCC), neoadjuvant chemoradiation only, or post‐operative chemotherapy only. Cox proportional hazard modeling identified age >90 and margin positivity as independent risk factors for decreased overall survival.ConclusionAnalysis of NCDB data for Stages II and III rectal cancer in patients over 80 shows a survival benefit of adjuvant and/or neoadjuvant therapy over surgery alone. There does not appear to be a difference in survival between patients who received neoadjuvant chemoradiation, post‐resection adjuvant chemotherapy, or GCC.

AbstractBackgroundRib fractures are common after chest wall trauma. For patients with flail chest, surgical stabilization is a promising technique for reducing morbidity. Anatomical difficulties often lead to an inability to completely repair the flail chest; thus, the result is partial flail chest stabilization (PFS). We hypothesized that patients with PFS have outcomes similar to those undergoing complete flail chest stabilization (CFS).MethodsA prospectively collected database of all patients who underwent rib fracture stabilization procedures from August 2009 until February 2013 was reviewed. Abstracted data included procedural and complication data, extent of stabilization, and pulmonary function test results.ResultsOf 43 patients who underwent operative stabilization of flail chest, 23 (53 %) had CFS and 20 (47 %) underwent PFS. Anterior location of the fracture was the most common reason for PFS (45 %). Age, sex, operative time, pneumonia, intensive care unit and hospital length of stay, and narcotic use were the same in both groups. Total lung capacity was significantly improved in the CFS group at 3 months. No chest wall deformity was appreciated on follow‐up, and no patients underwent additional stabilization procedures following PFS.ConclusionDespite advances in surgical technique, not all fractures are amenable to repair. There was no difference in chest wall deformity, narcotic use, or clinically significant impairment in pulmonary function tests among patients who underwent PFS compared with CFS. Our data suggest that PFS is an acceptable strategy and that extending or creating additional incisions for CFS is unnecessary.
