Abstract
Locally advanced rectal cancer has traditionally been treated with multimodal therapy including neoadjuvant chemoradiotherapy followed by surgical resection. More recent data suggests that in appropriate patients, total neoadjuvant treatment (TNT) makes it possible to adopt a "watch and wait" approach. Advocates for watch and wait argue that patients with a complete or near-complete clinical response to TNT have comparable overall and disease-free survival to their counterparts who undergo surgical resection, and also have a better quality of life, fewer complications, and potentially avoid a stoma. The dogma of surgery as regional curative intent therapy has been challenged by similar recurrence rates among those treated with total mesorectal excision (TME) and those treated with watch and wait. Furthermore, those who develop local recurrence in the watch and wait groups are equally salvageable, either by surgery, brachytherapy, or chemotherapy. While watch and wait is not appropriate in all patients, this manuscript highlights the benefits and drawbacks of both therapeutic modalities.

Abstract
BACKGROUND Colectomies and proctectomies are commonly performed by both general surgeons (GS) and colorectal surgeons (CRS). The aim of our study was to examine the outcomes of elective colectomy, urgent colectomy, and elective proctectomy according to surgeon training. STUDY DESIGN Data were obtained from the Vizient database for adults who underwent elective colectomy, urgent colectomy, and elective proctectomy from 2020-2022. Operations performed in the setting of trauma and patients within the database's highest relative expected mortality risk group were excluded. Outcomes were compared according to surgeon's specialty: GS vs. CRS. The primary outcome was in-hospital mortality. The secondary outcome was in-hospital complication rate. Data were analyzed using multivariate logistic regression. RESULTS Of 149,516 elective colectomies, 75,711(50.6%) were performed by GS and 73,805(49.4%) by CRS. Compared to elective colectomies performed by CRS, elective colectomies performed by GS had higher rates of complications(4.9% vs. 3.9%, OR1.23, 95%CI 1.17-1.29,p<.01) and mortality(0.5% vs. 0.2%, OR2.06, 95%CI 1.72-2.47,p<.01). Of 71,718 urgent colectomies, 54,680(76.2%) were performed by GS, while 17,038(23.8%) were performed by CRS. Compared to urgent colectomies performed by CRS, urgent colectomies performed by GS were associated with higher rates of complications(12.1% vs. 10.4%, OR1.14, 95%CI 1.08-1.20,p<.01) and mortality (5.1% vs. 2.3%, OR2.08, 95%CI 1.93-2.23,p<.01). Of 43,749 elective proctectomies, 28,458(65.0%) were performed by CRS and 15,291(35.0%) by GS. Compared to proctectomies performed by CRS, those performed by GS were associated with higher rates of complications (5.3% vs. 4.4%, OR1.16, 95%CI 1.06-1.27,p<.01) and mortality(0.3% vs. 0.2%, OR1.49, 95%CI 1.02-2.20,p=.04). CONCLUSIONS In this nationwide study, colectomies and proctectomies performed by CRS were associated with improved outcomes compared to GS. Hospitals without a CRS on staff should consider prioritizing recruiting CRS specialists.

Abstract
BACKGROUND The use of laparoscopic total gastrectomy for gastric cancer remains controversial. Our objective was to compare outcomes of laparoscopic total gastrectomy (LTG) vs. open total gastrectomy (OTG) for gastric adenocarcinoma using a national cancer database. METHODS The National Cancer Database (2010-2014) was analyzed for total gastrectomy cases performed for gastric adenocarcinoma. Patient demographics and surgical outcomes were stratified by stage and compared based on laparoscopic vs. open surgical approach. Primary outcome measures included 30-day and 90-day mortality and Kaplan-Meier curves to estimate long-term survival. RESULTS There were 2584 cases analyzed, including 592 (22.9%) stage I, 710 (27.5%) stage II, and 1282 (49.6%) stage III cases. The distribution of LTG vs. OTG cases was 156 (26.4%) vs. 436 (73.6%) for stage I, 163 (23.0%) vs. 547 (77.0%) for stage II, and 241 (18.8%) vs. 1041 (81.2%) for stage III. For all stages analyzed, there was no difference between laparoscopic vs. open approach for adjusted 30-day mortality (stage I: adjusted odds ratio (AOR) 0.52, p = 0.75; stage II: AOR 1.36, p > 0.99; stage III: AOR 0.46, p = 0.29) or 90-day mortality (stage I: AOR 0.46, p = 0.99; stage II: AOR 1.17, p = 0.99; stage III: 0.57, p = 0.29). There was no difference between LTG vs. OTG 5-year Kaplan-Meier estimated survival curves for any stage (stage I: p = 0.20; stage II: p = 0.83; stage III: p = 0.46). When compared to OTG, LTG had a similar hazard ratio (HR) for mortality (HR 0.89 p = 0.20). CONCLUSIONS Laparoscopic total gastrectomy and OTG have comparable 30-day mortality, 90-day mortality, and long-term survival.

Abstract
BACKGROUND Laparoscopic ileostomy closure with intracorporeal anastomosis offers potential advantages over open reversal with extracorporeal anastomosis, including earlier return of bowel function and reduced postoperative pain. In this study, we aim to compare the outcome and cost of laparoscopic ileostomy reversal (utilizing either intracorporeal or extracorporeal anastomosis) with open ileostomy reversal. METHODS A retrospective review of sequential patients undergoing elective loop ileostomy reversal between 2013 and 2016 at a single, high-volume institution was performed. Patients were stratified on the basis of operative approach: open reversal, laparoscopic-assisted reversal with extracorporeal anastomosis (LE), and laparoscopic reversal with intracorporeal anastomosis (LI). Linear and logistic regressions were utilized to perform multivariate analysis and determine risk-adjusted outcomes. RESULTS Of 132 sequential cases of loop ileostomy reversal, 50 (38%) underwent open, 49 (37%) underwent LE, and 33 (22%) underwent LI. Demographic data and preoperative comorbidities were similar between the three cohorts. Median length of stay was significantly shorter for LI (52.1 h, p < 0.05) compared to open (69.0 h) and LE (69.6 h). After risk-adjusted analysis, length of stay was significant shorter in LI compared to LE (GM 0.78, 95% CI 0.64-0.93, p < 0.01) and open reversal (GM 0.78, 95% CI 0.66-0.93, p < 0.01). Risk-adjusted 30-day morbidity rates were similar for LI compared to LE (OR 0.43, 95% CI 0.081-2.33, p = 0.33) and open reversal (OR 0.53, 95% CI 0.09-3.125, p = 0.48). Median in-hospital direct cost was similar for LI ($6575.00), LE ($6722.50), and open reversal ($6181.00). CONCLUSION Laparoscopic ileostomy reversal with intracorporeal anastomosis was associated with shorter length of stay without increased overall direct cost. The technique of laparoscopic ileostomy reversal warrants continued study in a randomized clinical trial.

Abstract
The focused assessment with sonography for trauma (FAST) examination has become the standard of care for rapid evaluation of trauma patients. Extended FAST (eFAST) is the use of ultra-sonography for the detection of pneumothorax (PTX). The exact sensitivity and specificity of eFAST detecting traumatic PTX during practical “real-life” application is yet to be investigated. This is a retrospective review of all trauma patients with a diagnosis of PTX, who were treated at a large level 1 urban trauma center from March 2013 through July 2014. Charts were reviewed for results of imaging, which included eFAST, chest X-ray, and CT scan. The requirement of tube thoracostomy and mechanism of injury were also analyzed. A total of 369 patients with a diagnosis of PTX were identified. A total of 69 patients were excluded, as eFASTwas either not performed or not documented, leaving 300 patients identified with PTX. A total of 113 patients had clinically significant PTX (37.6%), requiring immediate tube thoracostomy placement. eFAST yielded a positive diagnosis of PTX in 19 patients (16.8%), and all were clinically significant, requiring tube thoracostomy. Chest X-ray detected clinically significant PTX in 105 patients (92.9%). The literature on the utility of eFAST for PTX in trauma is variable. Our data show that although specific for clinically significant traumatic PTX, it has poor sensitivity when performed by clinicians with variable levels of ultrasound training. We conclude that CT is still the gold standard in detecting PTX, and clinicians performing eFAST should have adequate training.

Abstract
We assessed characteristics associated with community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) carriage among residents of 22 nursing homes. Of MRSA-positive swabs, 25% (208/824) were positive for CA-MRSA. Median facility CA-MRSA percentage was 22% (range, 0%-44%). In multivariate models, carriage was associated with age less than 65 years (odds ratio, 1.2; P<.001) and Hispanic ethnicity (odds ratio, 1.2; P=.006). Interventions are needed to target CA-MRSA.

Abstract
BACKGROUND MRSA prevalence in nursing homes often exceeds that in hospitals, but reasons for this are not well understood. We sought to measure MRSA burden in a large number of nursing homes and identify facility characteristics associated with high MRSA burden. METHODS We performed nasal swabs of residents from 26 nursing homes to measure MRSA importation and point prevalence, and estimate transmission. Using nursing home administrative data, we identified facility characteristics associated with MRSA point prevalence and estimated transmission risk in multivariate models. RESULTS We obtained 1,649 admission and 2,111 point prevalence swabs. Mean MRSA point prevalence was 24%, significantly higher than mean MRSA admission prevalence, 16%, (paired t-test, p<0.001), with a mean estimated MRSA transmission risk of 16%.In multivariate models, higher MRSA point prevalence was associated with higher admission prevalence (p=0.005) and higher proportions of residents with indwelling devices (p=0.01). Higher estimated MRSA transmission risk was associated with higher proportions of residents with diabetes (p=0.01) and lower levels of social engagement (p=0.03). CONCLUSIONS MRSA importation was a strong predictor of MRSA prevalence, but MRSA burden and transmission were also associated with nursing homes caring for more residents with chronic illnesses or indwelling devices. Frequent social interaction among residents appeared to be protective of MRSA transmission, suggesting that residents healthy enough to engage in group activities do not incur substantial risks of MRSA from social contact. Identifying characteristics of nursing homes at risk for high MRSA burden and transmission may allow facilities to tailor infection control policies and interventions to mitigate MRSA spread.

Abstract
Increased use of thoracic CT (TCT) in diagnosis of blunt traumatic injury has identified many injuries previously undetected on screening chest x-ray (CXR), termed “occult injury.” The optimal management of occult rib fractures, pneumothoraces (PTX), hemothoraces (HTX), and pulmonary contusions is uncertain. Our objective was to determine the current management and clinical outcome of these occult blunt thoracic injuries. A retrospective review identified patients with blunt thoracic trauma who underwent both CXR and TCT over a 2-year period at a Level I urban trauma center. Patients with acute rib fractures, PTX, HTX, or pulmonary contusion on TCT were included. Patient groups analyzed included: 1) no injury (normal CXR, normal TCT, n = 1337); 2) occult injury (normal CXR, abnormal TCT, n = 205); and 3) overt injury (abnormal CXR, abnormal TCT, n = 227). Patients with overt injury required significantly more mechanical ventilation and had greater mortality than either occult or no injury patients. Occult and no injury patients had similar ventilator needs and mortality, but occult injury patients remained hospitalized longer. No patient with isolated occult thoracic injury required intubation or tube thoracostomy. Occult injuries, diagnosed by TCT only, have minimal clinical consequences but attract increased hospital resources.
