Colorectal liver metastases (CRLM) are the most common cause of disease-specific mortality in patients with colorectal cancer. Hepatic artery infusion (HAI) combined with systemic chemotherapy improves survival for these patients. The safety of colorectal resection at the time of HAI pump placement has not been well established. Patients with CRLM who underwent combined HAI pump placement and colorectal (primary) resection or HAI pump placement alone were evaluated for perioperative outcomes, pump-specific complications, infectious complications, and time to treatment initiation. These outcomes were compared using comparative statistics. Patients who underwent combined HAI pump placement and primary resection (n = 19) vs HAI pump placement alone (n = 13) had similar demographics and rates of combined hepatectomy. Combined HAI pump placement and primary resection group had similar operative time and blood loss (both p = NS), but longer length of stay (6 vs 4 days, p = 0.02) compared to pump placement alone. Overall postoperative complications (21% vs 8%) and pump-specific complications (16% vs 31%) were similar (both p = NS). Infection rates were not different between groups, nor was time to initiation of HAI therapy (19 vs 16 days p = NS), or systemic therapy (34 vs 35 days p = NS). Combining colorectal resection with HAI pump implantation is a safe surgical approach for management of unresectable CRLM. Postoperative complications, specifically infectious complications, were not increased, nor was there a delay to initiation of HAI or systemic chemotherapy. Investigation of long-term oncologic outcomes for HAI pump placement and primary tumor resection in patients with unresectable CRLM is ongoing.

To evaluate health care fragmentation in patients with stage II and III rectal cancers. Fragmentation of care among multiple hospitals may worsen outcomes for cancer patients. National Cancer Database was queried for adult patients who underwent radiation and surgery for locally advanced (stage II–III) rectal adenocarcinoma from 2006 to 2015. Fragmented care was defined as receiving radiation at a different hospital from surgery. Descriptive statistics characterized patients, and survival probability was plotted using the Kaplan-Meier method and a Cox proportional hazards model. A total of 37,081 patients underwent surgery and radiation for stage II–III rectal cancer from 2006 to 2015 (24,102 integrated care vs. 12,979 fragmented care). Patients who received fragmented care (hazard ratio [HR] 1.105; 95% CI 1.045–1.169) had a higher risk of mortality. Patients who received at least surgery (HR 0.84; 95% CI 0.77–0.92) at academic hospitals had a lower risk of mortality. Academic hospitals had a higher proportion of patients with fragmented care (38.0 vs. comprehensive community 32.8% vs. community 33.8%, p

PURPOSE: Previous studies have demonstrated improved outcomes at high-volume colorectal surgery centers, however the benefit for patients who live far from such centers has not been assessed relative to local, low-volume facilities. METHODS: The 2010–2015 National Cancer Database (NCDB) was queried for patients with stage I-III colon adenocarcinoma undergoing treatment at a single center. A ‘local, low-volume’ cohort was constructed of 12,768 patients in the bottom quartile of travel distance at the bottom quartile of institution surgical volume and a ‘travel, high-volume’ cohort of 11,349 patients in the top quartile of travel distance at the top quartile of institution surgical volume. RESULTS: In unadjusted analysis, patients in the travel cohort had improved rates of positive resection margins (3.7% vs. 5.5%, p

Preoperative assessment typically equates to evaluating and accepting the presenting condition of the patient (unless extreme) and commonly occurs only a few days before the planned surgery. While this timing enables a preoperative history and examination and mitigates unexpected findings on the day of surgery that may delay throughput, it does not allow for meaningful preoperative management of modifiable medical conditions. Evidence is limited regarding how best to balance efforts to mitigate modifiable risk factors versus the timing of surgery. Furthermore, while the concept of preoperative risk modification is not novel, evidence is lacking for successful and sustained implementation of such an interdisciplinary, collaborative program. A better understanding of perioperative care coordination and, specifically, implementing a preoperative preparation process can enhance the value of surgery and surgical population health. In this article, we describe the implementation of a collaborative preoperative clinic with the primary goal of improving patient outcomes.

As the use of minimally invasive techniques in colorectal surgery has become increasingly prevalent, concerns remain about the oncologic effectiveness and long-term outcomes of minimally invasive low anterior resection (MI-LAR) for the treatment of rectal cancer. The 2010–2015 National Cancer Database (NCDB) Participant Data Use File was queried for patients undergoing elective open LAR (OLAR) or MI-LAR for rectal adenocarcinoma. A 1:1 propensity match was performed on the basis of demographics, comorbidity, and tumor characteristics. Outcomes were compared between groups and Cox proportional hazard modeling was performed to identify independent predictors of mortality. A subset analysis was performed on high-volume academic centers. 35,809 patients undergoing LAR were identified of whom 18,265 (51.0%) underwent MI-LAR. After propensity matching, patients receiving MI-LAR were less likely to have a positive circumferential radial margin (CRM) (5.5% vs. 6.6%, p = 0.0094) or a positive distal margin (3.6% vs. 4.6%, p = 0.0022) and had decreased 90-day all-cause mortality (2.0% vs. 2.6%, p = 0.0238). MI-LAR resulted in decreased hospital length of stay (5 vs. 6 days, p

Due to conflicting study results on the effect of laterality on overall survival in primary colon cancers, we sought to examine the impact of left compared to right-sided primary tumors on overall survival for stage I–III colon cancer using the largest dataset to date. The 2006–2013 NCDB was queried for patients with single primary, stage I–III colon adenocarcinoma and grouped by stage and tumor location. For stage I–II tumors, 114,839 patients had resection (62% right:38% left). After adjustment, patients with right-sided tumors had superior survival ([HR right as reference]: 1.13, 95% CI 1.09–1.17, p

Background In 2017, our hospital was identified as a high outlier for postoperative Clostridium difficile infections (CDIs) in the American College of Surgeons NSQIP semi-annual report. The Department of Surgery initiated a CDI task force with representation from Surgery, Infectious Disease, Pharmacy, and Performance Services to analyze available data, identify opportunities for improvement, and implement strategies to reduce CDIs. Study Design Strategies to reduce CDIs were reviewed from the literature and the following multidisciplinary strategies were initiated: antimicrobial stewardship optimization of perioperative order sets to avoid cefoxitin and fluoroquinolone use was completed; penicillin allergy assessment and skin testing were implemented concomitantly; increased use of ultraviolet disinfectant strategies for terminal cleaning of CDI patient rooms; increased hand hygiene and personal protection equipment signage, as well as monitoring in high-risk CDI areas; improved diagnostic stewardship by an electronic best practice advisory to reduce inappropriate CDI testing; education through surgical grand rounds; and routine data feedback via NSQIP and National Healthcare Safety Network CDI reports. Results The observed rate of CDIs decreased from 1.27% in 2016 to 0.91% in 2017. Cefoxitin and fluoroquinolone use decreased. Clostridium difficile infection testing for patients on laxatives decreased. Terminal cleaning with ultraviolet light increased. Handwashing compliance increased. Data feedback to stakeholders was established. Conclusions Our multidisciplinary CDI reduction program has demonstrated significant reductions in CDIs. It is effective, straightforward to implement and monitor, and can be generalized to high-outlier institutions.

Controversy exists over the use of adjuvant chemotherapy for locally advanced (stages II–III) rectal cancer (LARC) patients who demonstrate pathologic complete response (pCR) following neoadjuvant chemoradiation. We conducted a retrospective analysis to determine whether adjuvant chemotherapy imparts survival benefit among this population. The National Cancer Database (NCDB) was queried to identify LARC patients with pCR following neoadjuvant chemoradiation. The cohort was stratified by receipt of adjuvant chemotherapy. Multiple imputation and a Cox proportional hazards model were employed to estimate the effect of adjuvant chemotherapy on overall survival. There were 24,418 patients identified in the NCDB with clinically staged II or III rectal cancer who received neoadjuvant chemoradiation. Of these, 5606 (23.0%) had pCR. Among patients with pCR, 1401 (25%) received adjuvant chemotherapy and 4205 (75%) did not. Patients who received adjuvant chemotherapy were slightly younger, more likely to have private insurance, and more likely to have clinically staged III disease, but did not differ significantly in comparison to patients who did not receive adjuvant chemotherapy with respect to race, sex, facility type, Charlson comorbidity score, histologic tumor grade, procedure type, length of stay, or rate of 30-day readmission following surgery. On adjusted analysis, receipt of adjuvant chemotherapy was associated with a lower risk of death at a given time compared to patients who did not receive adjuvant chemotherapy (HR 0.808; 95% CI 0.679–0.961; p = 0.016). Supporting existing NCCN guidelines, the findings from this study suggest that adjuvant chemotherapy improves survival for LARC with pCR following neoadjuvant chemoradiation.

Background Controversy exists regarding current National Comprehensive Cancer Network guidelines, which recommend local excision for rectal carcinoids ≤2 cm and radical resection for tumors >2 cm. Given the limited data examining optimal surgical approach for these lesions, we queried a national database to determine the impact of extent of resection on survival. Methods Patients undergoing treatment for clinical stage I and II rectal carcinoid (RC) were identified from the National Cancer Data Base (1998-2012). The association between extent of surgery, tumor size, and the likelihood of pathologic lymph node positivity was examined. Kaplan–Meier analysis was used to compare overall survival. Results In total, 1900 patients were identified, of whom 1644 (86.5%) were treated with local excision, and 256 (13.5%) were treated with radical resection. A significant majority of patients with tumors ≤2.0 cm (89.0%) and nearly half with tumors 2.1-4.0 cm (44.8%) or >4.0 cm (45.8%) underwent local excision. Nodal positivity was correlated with tumor size (7.1% positivity with ≤2.0 cm tumors, 31.3% with 2.1-4.0 cm tumors, and 50.0% with >4 cm tumors). However, 5-y survival was equivalent between surgical approaches for tumors ≤2 cm (93.0% versus 93.0%) and tumors 2.1-4.0 cm (76.0% versus 76.0%). Conclusions We demonstrate in early-stage RC that nearly half of intermediate and large tumors are being treated with local excision outside National Comprehensive Cancer Network guidelines. In addition, radical resection does not appear to be associated with improved overall survival for tumors of any size. These findings suggest that the preferred approach to early-stage RCs without aggressive biological characteristics is local excision due to the decreased morbidity and mortality versus radical resection.

Adjuvant chemotherapy after resection is the standard of care for stage III colon cancer, yet many patients omit chemotherapy. We aimed to describe the impact of delayed chemotherapy on overall survival across multiple time points.The 2006 to 2014 National Cancer Data Base (NCDB) was queried for patients with single primary stage III adenocarcinoma of the colon. Patients were grouped by receipt and timing of chemotherapy from resection date: chemotherapy omitted,6 weeks, 6 to 8 weeks, 8 to 12 weeks, 12 to 24 weeks, and24 weeks. Subgroup analyses were performed for those with comorbidities and those who had postoperative complications. Overall survival was compared using Cox proportional hazard modeling, adjusting for patient, tumor, and facility characteristics.In total, 72,057 patients were included; 20,807 omitted chemotherapy, 22,705 received it at6 weeks, 15,412 between 6 and 8 weeks, 9,049 between 8 and 12 weeks, 3,595 between 12 and 24 weeks, and 489 at24 weeks after resection. Compared with patients who omitted chemotherapy, patients who received chemotherapy at6 weeks (hazard ratio [HR] 0.44), 6 to 8 weeks (HR 0.45), 8 to 12 weeks (HR 0.52), 12 to 24 weeks (HR 0.61), and24 weeks (HR 0.68) had superior overall survival (p0.001). This survival benefit was preserved across subgroups (p0.001).After resection of stage III colon cancer, patients should receive adjuvant chemotherapy within 6 to 8 weeks for maximal benefit. However, chemotherapy should be offered to patients who are outside the optimal window, who have significant comorbidities, or who have had a complication more than 24 weeks from resection to improve the overall survival compared with omitting chemotherapy.

Background Our study compares 30-day vs. 90-day mortality following colorectal cancer surgery (CRS), and examines hospital performance ranking based on this assessment. Methods Mortality rates were compared between 30 vs. 90 days following CRS for patients with stage I-III colorectal cancers from the National Cancer Database (2004–2012). Risk-adjusted hierarchical regression models evaluated hospital performance based on mortality. Hospitals were ranked into top (10%), middle (80%), and lowest (10%) performance groups. Results Among 185,464 patients, 90-day mortality was nearly double the 30-day mortality (4.4% vs. 2.5%). Following risk adjustment 176 hospitals changed performance ranking: 39% in the top 30-day mortality group changed ranking to the middle group; 37% of hospitals in the lowest 30-day group changed ranking to the middle 90-day group. Conclusions Evaluation of hospital performance based on 30-day mortality is associated with misclassification for 15% of hospitals. Ninety-day mortality may be a better quality metric in oncologic CRS.

Aim To examine the overall survival differences of neoadjuvant therapy modalities: no therapy, chemotherapy alone, radiation alone, and chemoradiation in a large cohort of patients with locally advanced rectal cancer. Method Adults with clinical stage II and III rectal adenocarcinoma were selected from the National Cancer Database and grouped by type of neoadjuvant therapies received: no therapy, chemotherapy only, radiotherapy only, or chemoradiation. Multivariable regression methods were used to compare adjusted differences in perioperative outcomes and overall survival. Results Among 32978 patients included, 9714 (29.5%) received no neoadjuvant therapy, 890 (2.7%) chemotherapy only, 1170 (3.5%) radiotherapy only, and 21204 (64.3%) chemoradiation. Compared to no therapy, chemotherapy or radiotherapy alone was not associated with any adjusted differences in surgical margin positivity, permanent colostomy rate, or overall survival (all p > 0.05). With adjustment, neoadjuvant chemoradiation vs. no therapy was associated with a lower likelihood of surgical margin positivity (OR 0.74, p < 0.001), decreased rate of permanent colostomy (OR 0.77, p < 0.001), and overall survival (HR 0.79, p < 0.001). When compared to chemotherapy or radiotherapy alone, chemoradiation remain associated with improved overall survival (vs. chemotherapy alone: HR 0.83, p = 0.04; vs. radiotherapy alone: HR 0.83, p < 0.019). Conclusions Neoadjuvant chemoradiation, not chemotherapy or radiotherapy alone, is important for sphincter preservation, R0 resection, and survival for patients with locally advanced rectal cancer. Despite this finding, one-third of patients in the United States with locally advanced rectal cancer fail to receive stage-appropriate chemoradiation. This article is protected by copyright.

Healing of pilonidal cysts after initial excision remains a vexing problem for surgeons. While simple sinus can be managed with success, recurrence of the cyst after primary excision or sizeable sinus often requires a more complex repair; however, the morbidity and ultimate success of these procedures are unknown. A retrospective review from 2009 to 2014 of all consecutive patients undergoing surgical intervention for pilonidal cyst disease from a single institution was performed. Management of pilonidal disease after excision with flap coverage was examined. Patient demographics, co-morbidities, procedural data, and post-operative outcomes were analyzed. Twenty-one flap patients were identified. These included 15 V-Y fasciocutaneous repairs, 5 rotational flaps, and 1 Romberg flap closure. Mean BMI was 32, mean defect size was 8 cm, and the patients have had an average of 1.05 attempts prior to the excision and flap repair. The flap group demonstrated 14% recurrence rate, 33% reoperation rate, and 47% dehiscence rate. Mean time to healing was 36.4 days. Flap repairs for complex pilonidal cysts have high rates of recurrence, reoperation, and wound dehiscence. However, flap patients represent a more challenging repair with long operative times, blood loss, and large sinus size. Absence of the perfect approach to managing a complex sinus necessitates a thorough description of the problem and a discussion between the surgeon and the patient about the merits of each approach before a decision is made. Level of Evidence: Level IV, therapeutic study.

Hypoalbuminemia is associated with adverse surgical outcomes. A minimum threshold and the impact of incrementally decreasing albumin remain undefined for colorectal surgery patients. The 2011–2013 National Surgical Quality Improvement Program (NSQIP) dataset was queried for patients undergoing elective colorectal surgery. Multivariable regression analyses with restricted cubic splines (RCS) were used to examine the adjusted association between preoperative serum albumin level and the incidence of complications and to establish an optimal threshold. RCS allows for flexible evaluation in multivariable models without having to assume a specific relationship a priori. Sixteen thousand one hundred forty-five patients met study criteria. RCS analysis demonstrated an inflection point at serum albumin level of 3.9 mg/dL. Patients with preoperative albumin

Purpose/objectives To test effects of gain-framed versus loss-framed mailed brochures on increasing physical activity (PA) among colorectal cancer (CRC) survivors. . Design Randomized trial with repeated measures at baseline, 1 month, and 12 months postintervention. . Setting Mail recruitment from tumor registries. . Sample 148 inactive CRC survivors who had completed primary therapy. . Methods PA and constructs from the Theory of Planned Behavior (TPB) were assessed at baseline, 1 month, and 12 months. Participants were randomized to receive pamphlets describing PA benefits (gain framed) or disadvantages of not being physically active (loss framed). Baseline characteristics were compared using descriptive statistics. Repeated measures linear models were used to test PA changes. . Main research variables Minutes of PA and TPB constructs. . Findings Significant PA increases were observed in both study arms. Results did not differ by message frame. At one month, about 25% of previously inactive participants increased activity to national recommendations. Those who increased PA compared to those who did not had higher baseline scores on subjective norms, perceived behavioral control, and PA intentions. . Conclusions Independent of message framing, mailed brochures are highly effective in producing within-subject short- and long-term increases in PA. . Implications for nursing CRC survivors may increase short- and long-term levels of PA by receiving inexpensive print brochures.

The use of intensity-modulated radiation therapy (IMRT) in rectal cancer has steadily increased over traditional 3D conformal radiotherapy (3D-CRT) due to perceived benefit of delivering higher treatment doses while minimizing exposure to surrounding tissues. However, IMRT is technically challenging and costly, and its effects on rectal cancer outcomes remain unclear.Adults with clinical stage II and III rectal adenocarcinoma who underwent neoadjuvant chemoradiotherapy with 45-54 Gy of radiation and surgery were included from the 2006-2013 National Cancer Data Base. Patients were grouped based the modality of radiation received: IMRT or 3D-CRT. Multivariable regression modeling adjusting for demographic, clinical, and treatment characteristics was used to examine the impact of IMRT vs. 3D-CRT on pathologic downstaging, resection margin positivity, sphincter loss surgery, 30-day unplanned readmission and mortality after surgery, and overall survival.Among 7386 patients included, 3330 (45 %) received IMRT and 4056 (55 %) received 3D-CRT. While the mean radiation dose delivered was higher with IMRT (4735 vs. 4608 cGy, p 0.001), it was associated with higher risks of positive margins (adjusted odds ratio (OR) 1.57; p 0.001) and sphincter loss surgery (OR 1.32; p 0.001). There were no differences between IMRT and 3D-CRT in the likelihood of pathologic downstaging (OR 0.89, p = 0.051), unplanned readmission (OR 0.79; p = 0.07), or 30-day mortality (OR 0.61; p = 0.31) after surgery. Additionally, there were no differences in overall survival at 8 years (IMRT vs. 3D-CRT: 64 vs. 64 %; adjusted hazard ratio 1.06, p = 0.47).IMRT is associated with worse local tumor control without any long-term survival benefit for patients with locally advanced rectal cancer. Given the lack of significant advantage and the higher cost of IMRT, caution should be exercised when using IMRT instead of traditional 3D-CRT for rectal cancer.

To examine the impact of alvimopan on outcomes and costs in a rigorous enhanced recovery colorectal surgery protocol.Postoperative ileus remains a major source of morbidity and costs in colorectal surgery. Alvimopan has been shown to reduce incidence of postoperative ileus in enhanced recovery colorectal surgery; however, data are equivocal regarding its benefit in reducing length of stay and costs.Patients undergoing major elective enhanced recovery colorectal surgery were identified from a prospectively-collected database (2010-2013). Multivariable analyses were employed to compare outcomes and hospital costs among patients who had alvimopan versus no alvimopan by adjusting for demographic, clinical, and treatment characteristics.A total of 660 patients were included; 197 patients received alvimopan and 463 patients had no alvimopan. In unadjusted analysis, the alvimopan group had a faster return of bowel function, shorter length of stay, and lower rates of ileus, Foley re-insertion, and urinary tract infection (all P 0.01). After adjustment, alvimopan was associated with a faster return of bowel function by 0.6 day (P = 0.0006), and lower incidence of postoperative ileus (odds ratio 0.23, P = 0.0002). With adjustment, alvimopan was associated with a shorter length of stay by 1.6 days (P = 0.002), and a hospital cost savings of $1492 per patient (P = 0.01).Alvimopan administration as an element of enhanced recovery colorectal surgery is associated with faster return of bowel function, lower incidence of postoperative ileus, shorter hospitalization, and a significant cost savings. These results suggest that alvimopan is cost-effective in the setting of enhanced recovery colorectal surgery protocols, and should therefore be considered in these programs.

To examine survival of patients who underwent minimally invasive versus open low anterior resection (LAR) for rectal cancer.Utilization of laparoscopic and robotic LAR for rectal cancer has steadily increased. Short-term outcomes between these techniques and open surgery have shown equivalent results; however, survival outcomes are unknown.Adults from the National Cancer Data Base undergoing LAR for rectal adenocarcinoma were identified. Patients were stratified by intent-to-treat into open (OLAR) or minimally invasive LAR (MI-LAR). Multivariable modeling was used to compare short-term outcomes and survival between MI-LAR and OLAR and between laparoscopic (LLAR) and robotic LAR (RLAR).Among 14,033 patients included, 57.8% underwent OLAR and 42.2% MI-LAR. After adjustment, MI-LAR was associated with shorter length of stay (P 0.001), but similar rates of positive margins, 30-day readmission, 30-day mortality, and use of adjuvant therapies (all P 0.05). At 36 months, there was no difference in adjusted risk of mortality between MI-LAR and OLAR (hazard ratio [HR] 0.88, P = 0.089). In a subgroup analysis of LLAR versus RLAR, there were no differences in lymph node harvest, margin positivity, length of stay, readmission rate, 30-day mortality, or overall survival after adjustment (all P 0.05).Minimally invasive LAR for rectal cancer is associated with similar overall survival with the benefit of shorter hospitalization. Although the conversion rate is lower, robotic LAR is not associated with superior oncologic outcomes compared to laparoscopic LAR. Our findings support the ongoing adoption of minimally invasive techniques for rectal adenocarcinoma.

Controversy exists over whether resection of the primary tumor in stage IV colorectal cancer with inoperable metastases improves patient outcomes.The purpose of this study was to evaluate whether resection of the primary tumor without metastasectomy in patients with stage IV colorectal cancer is associated with improved overall survival compared with patients undergoing chemotherapy and/or radiation therapy alone.This was a retrospective review of a multi-institutional dataset.This study was conducted in all participating commission on cancer (CoC)-accredited facilities.The 2003-2006 National Cancer Data Base was reviewed to identify patients with stage IV adenocarcinoma of the colon or rectum who underwent palliative treatment without curative intent, either in the form of surgical resection of the primary tumor without metastasectomy consisting of a colectomy or rectal resection with or without chemotherapy and/or radiation or chemotherapy and/or radiation alone.Groups were compared for baseline characteristics. Overall survival was compared using Kaplan-Meier analysis before and after propensity matching with a 1:1 nearest-neighbor algorithm.Of the 1446 patients included in the analysis, 231 (16%) underwent surgical resection of the primary tumor without metastasectomy. Surgical resection was associated with a significant survival benefit on unadjusted analysis (median survival, 9.2 vs. 7.6 months; p0.01). After propensity matching to adjust for nonrandom treatment selection, surgical resection continued to be associated with a significant survival benefit (median survival, 9.2 vs. 7.3 months; p0.01).This study was limited by the potential for selection bias regarding which patients received surgical resection. There was also a lack of data regarding the indication for operation, specifically whether a patient was symptomatic or asymptomatic before resection. The inability to account for tumor size or grade among patients who did not receive surgical resection was another limitation.Surgical resection of the primary tumor without metastasectomy in patients with metastatic colorectal cancer is associated with improved survival as compared with chemotherapy/radiation therapy alone. Additional research is necessary to determine which patients may benefit from this intervention.

Improvements in diagnosis and treatment have resulted in significant improvement in survival rates for rectal cancer. This has led to increasing focus on post-treatment quality of life. One common sequela of treatment for rectal cancer is urinary dysfunction, defined as either difficulty voiding or incontinence. This consists of multiple clinical syndromes of distinct etiologies, most commonly dysfunction of the pelvic autonomic nerves or pelvic floor instability. This can vary in both duration and severity, with some patients experiencing transient and mild symptoms, while others experience prolonged functional impairment. A number of treatment options exist, including behavioral, pharmacologic, and surgical interventions. Because of the multifaceted nature of this process, optimal symptom relief requires careful evaluation of the severity and etiology of a patient’s complaints. Ultimately post-treatment urinary dysfunction can have a significant impact on quality of life, and it is important for clinicians to understand both the causes and management of this process.

Several reports suggest that the efficacy of adjuvant chemotherapy on survival diminishes over time for colon cancer; however, precise timing of its loss of benefit has not been established.This study aimed to determine the relationship between time to adjuvant chemotherapy and survival and to identify a threshold for increased risk of mortality.This was a retrospective study. Multivariable Cox proportional hazard modeling with restricted cubic splines was used to evaluate the adjusted association between time to adjuvant chemotherapy and overall survival and to establish an optimal threshold for the initiation of therapy.Data were collected from the National Cancer Data Base.Adults who received adjuvant chemotherapy following resection of stage II to III colon cancers were selected.The primary outcome measured was overall survival.A total of 7794 patients were included. After adjusting for clinical, tumor, and treatment characteristics, our model determined a critical threshold of chemotherapy initiation at 44 days from surgery, after which there was an increase in the overall mortality. At a median follow-up of 61 months, the risk of mortality was increased in those who received adjuvant chemotherapy after 44 days from surgery (adjusted HR, 1.14; 95% CI, 1.05-1.24; p = 0.002), but not in those who received chemotherapy before 44 days from surgery (p = 0.11). Each additional week of delay was associated with a 7% decrease in survival (HR, 1.07; 95% CI, 1.04-1.10; p0.001).This study was limited by selection bias and the inability to compare specific chemotherapy regimens.This study objectively determines the optimal timing of adjuvant chemotherapy for patients with resected colon cancer. Delay beyond 6 weeks is associated with compromised survival. These findings emphasize the importance of the timely initiation of therapy, and suggest that efforts to enhance recovery following surgery have the potential to improve survival by decreasing delay to adjuvant chemotherapy.

Primary perineal closure following abdominal perineal resection (APR) is reported to have a wound complication rate as high as 66%, whereas flap reconstruction reduces wound complications to 15% to 35%. A modified de-epithelialized V-Y fasciocutaneous flap aims to further improve results in this patient population.To study the breaking force of a simple interrupted suture in either skin or subcutaneous fat, various quantitative assessments were performed in a porcine flap model using uniaxial static tensile testing with an Instron tensiometer, with a single or triple row of 3 Vicryl sutures in both skin and fat.An outcomes analysis was performed in 24 patients who underwent modified V-Y flap reconstruction after APR. Primary outcome was wound complications including infection, dehiscence, seroma, hematoma, and pelvic fluid collections.Tensile strength of sutures anchored in skin was found to be up to 8 times stronger than sutures anchored in subcutaneous fat in a single row and 3 times as strong in 3 rows (breaking force, 500.2 N vs 263.7 N). In our patient cohort of 24 irradiated cancer patients, 10 (42%) had wound healing complications. Wound dehiscence of various degrees accounted for 80% of these complications. Five patients with wound complications (50%) had associated pelvic fluid collections (infection, 1; wound dehiscence, 4). Minor dehiscence was more likely to occur after suture removal and less likely to be associated with pelvic collections compared to patients with major dehiscence. Our study yields total complication rates lower than what is reported in the literature for anterolateral thigh or gracilis flap including much lower infection rates, and almost similar results to the commonly used vertical rectus myocutaneous muscle.Tension-free de-epithelialized V-Y flap use after APR effectively reconstructs the defect while eliminating an additional donor site. Benchtop studies suggest enhanced flap integrity yielded by layered closure. Wound complications can be managed with local care in their majority (90%). Staggering or delaying suture removal can decrease minor dehiscence. Based on analysis of our results, review of the literature and consideration of donor site morbidity, we believe that modified V-Y flap is the best approach for APR reconstruction in irradiated patients.

BACKGROUND Surgeons present patients with complex information at the perioperative appointment. Emotions likely play a role in surgical decision-making, and disgust is an emotion of revulsion at a stimulus that can lead to avoidance. OBJECTIVE The purpose of this study was to determine the impact of disgust on intention to undergo surgical resection for colorectal cancer and recall of perioperative instructions. DESIGN This was a cross-sectional observational study conducted online using hypothetical scenarios with nonpatient subjects. SETTINGS The study was conducted using Amazon's Mechanical Turk. PATIENTS Survey respondents were living in the United States. MAIN OUTCOME MEASURES Surgery intention and recall of perioperative instructions were measured. RESULTS A total of 319 participants met the inclusion criteria. Participants in the experimental condition, who were provided with detailed information and pictures about stoma care, had significantly lower surgery intentions (mean ± SD, 4.60 ± 1.15) compared with the control condition with no stoma prompt (mean ± SD, 5.14 ± 0.91; p = 0.05) and significantly lower recall for preoperative instructions (mean ± SD, 13.75 ± 2.38) compared with the control condition (mean ± SD, 14.36 ± 2.19; p = 0.03). Those within the experimental conditions also reported significantly higher state levels of disgust (mean ± SD, 4.08 ± 1.74) compared with a control condition (mean ± SD, 2.35 ± 1.38; p < 0.001). State-level disgust was found to fully mediate the relationship between condition and recall (b = -0.31) and to partially mediate the effect of condition on surgery intentions (b = 0.17). LIMITATIONS It is unknown whether these results will replicate with patients and the impact of competing emotions in clinical settings. CONCLUSIONS Intentions to undergo colorectal surgery and recall of preoperative instructions are diminished in patients who experience disgust when presented with stoma information. Surgeons and care teams must account for this as they perform perioperative counseling to minimize interference with recall of important perioperative information.

Recent studies have shown that hospital type impacts patient outcomes, but no studies have examined hospital differences in outcomes for patients undergoing minimally invasive surgery (MIS) for segmental colectomies. The 2010–2014 National Cancer Data Base was queried for patients undergoing segmental colectomy for non-metastatic colon adenocarcinoma. Descriptive statistics characterized MIS utilization by hospital type. Multivariable models were used to examine the effect of hospital type on outcomes after MIS. Survival probability was plotted using the Kaplan–Meier method. 80,922 patients underwent MIS segmental colectomy for colon cancer from 2010 to 2014. From 2010 to 2014, the number of MIS segmental colectomies increased by 157% at academic hospitals, 151% at comprehensive hospitals, and 153% at community hospitals. Compared to academic hospitals, community and comprehensive hospitals had greater adjusted odds of positive margins (Community OR 1.525, 95% Confidence Interval 1.233–1.885; Comprehensive OR 1.216, 95% CI 1.041–1.42), incomplete number of lymph nodes analyzed (

OBJECTIVE This study examines short-term outcomes and pathologic surrogates of oncologic results among patients undergoing robotic versus laparoscopic low anterior resection for rectal cancer. A total of 6403 patients met inclusion criteria. Although the robotic approach required significantly fewer conversions to open, surrogates for proper oncologic surgery were nearly identical between the 2 approaches. BACKGROUND Although laparoscopic low anterior resection (LLAR) has gained popularity as an acceptable approach, the robotic low anterior resection (RLAR) remains largely unproven. We compared short-term oncologic outcomes between rectal cancer patients undergoing either RLAR or LLAR. STUDY DESIGN All patients with rectal cancer in the National Cancer Data Base undergoing RLAR or LLAR from 2010 to 2011 were included. Predictors of RLAR were modeled with multivariable logistic regression. Groups were matched on propensity to undergo RLAR. Primary endpoints included lymph node retrieval and margin status, whereas secondary 30-day outcomes were mortality, hospital length of stay (LOS), and unplanned readmission rates. RESULTS A total of 6403 patients met inclusion criteria, of which 956 (14.9%) underwent RLAR. RLAR patients were more likely to be treated at academic centers, receive neoadjuvant therapy, and have higher T-stage and longer time to surgery (all P

Practice guidelines differ in their support of adjuvant chemotherapy use in patients who received preoperative chemoradiation for rectal cancer.The purpose of this study was to evaluate the impact of adjuvant chemotherapy among patients with locally advanced rectal cancer who received neoadjuvant chemoradiation and surgery.This was a retrospective study. Multivariable Cox proportional hazard modeling was used to evaluate the adjusted survival differences.Data were collected from the National Cancer Database.Adults with pathologic stage II and III rectal adenocarcinoma who received neoadjuvant chemoradiation and surgery were included.Overall survival was measured.Among 12,696 patients included, 4023 (32%) received adjuvant chemotherapy. The use of adjuvant chemotherapy increased over the study period from 23% to 36%. Although older age and black race were associated with a lower likelihood of receiving adjuvant chemotherapy, patients with higher education level and stage III disease were more likely to receive adjuvant chemotherapy (all p0.05). At 7 years, overall survival was improved among patients who received adjuvant chemotherapy (60% vs. 55%; p0.001). After risk adjustment, the use of adjuvant chemotherapy was associated with improved survival (HR = 0.81 (95% CI, 0.72-0.91); p0.001). In the subgroup of patients with stage II disease, survival was also improved among patients who received adjuvant chemotherapy (68% vs 58% at 7 y; p0.001; HR = 0.70 (95% CI, 0.57-0.87); p = 0.002). Among patients with stage III disease, the use of adjuvant chemotherapy was associated with a smaller but persistent survival benefit (56% vs 51% at 7 y; p = 0.017; HR = 0.85 (95% CI, 0.74-0.98); p = 0.026).The study was limited by its potential for selection bias and inability to compare specific chemotherapy regimens.The use of adjuvant chemotherapy among patients with rectal cancer who received preoperative chemoradiation conferred a survival benefit. This study emphasizes the importance of adjuvant chemotherapy in the management of rectal cancer and advocates for its increased use in the setting of neoadjuvant therapy.

BACKGROUND: Our study aims to identify the minimum number of lymph nodes (LN) associated with improved survival in patients who underwent NRT for stage II-III rectal cancer. METHODS: Adults with clinical stage II and III rectal adenocarcinoma in the National Cancer Data Base were stratified by NRT. Multivariable Cox regression modeling with restricted cubic splines was used to determine the minimum number of LNs associated with improved survival. RESULTS: Of 38,363 patients, 76% received NRT. After adjustment, a LNY≥12 was associated with improved survival among patients receiving NRT (HR 0.79, p < 0.0001) and those without NRT (HR 0.88, p = 0.04). Among patients receiving NRT, factors independently associated with LNY≥12 were younger age, private insurance, low comorbidity score, a recent year of diagnosis, higher T stage and grade, APR resection, and academic institution. CONCLUSIONS: A minimum LNY of 12 confers a survival benefit for rectal cancer patients regardless of receiving neoadjuvant radiation therapy.

Contemporary treatment of node-positive (N+) colon cancer consists of adjuvant chemotherapy; however, randomized data supporting this practice were derived from lesions T2 or greater. Minimal data exist regarding the use and need for adjuvant chemotherapy in T1N+ disease.The aim of this study was to determine treatment trends and the effects of adjuvant chemotherapy on T1N+ colon cancers by using the National Cancer Database.This was a retrospective study. Baseline demographics, tumor, and cancer treatment characteristics were compared. Groups were matched on the propensity to receive chemotherapy. Adjusted long-term survival stratified by chemotherapy use was compared by using the Kaplan-Meier method with the log-rank test. Predictors of not receiving chemotherapy were identified by using a multivariable logistic regression model.Data were collected from the National Cancer Database, which collects cancer data from over 1500 cancer centers.We identified patients from 1998 to 2006 with T1N+ disease, excluding those with metastatic disease or previous cancer. Patients were stratified based on whether or not they received chemotherapy.The primary outcome measure of this study was long-term survival.Three thousand one hundred thirty-seven patients had T1N+ disease; 70.6% (n = 2216) received chemotherapy, and utilization significantly increased from 1998 to 2011 (p0.001). Unadjusted analysis revealed that patients treated with chemotherapy were statistically younger and healthier, and had shorter postoperative lengths of stay (all p0.001). Unadjusted 5-year survival was higher in patients receiving chemotherapy (87.9% vs 63.0% in patients with no chemotherapy; p0.001) and this persisted after propensity matching with (83.4% and 63.0% in patients with or without chemotherapy; p0.001). Only age (OR, 0.29; p0.001) predicted not receiving chemotherapy.Limitations include potential selection bias as well as the inability to compare disease-free survival/recurrence.Adjuvant chemotherapy appears to significantly improve long-term survival in patients receiving chemotherapy in T1N+ disease. Thus, the use of chemotherapy in T1N+ disease is justified and provides a highly significant survival benefit.

Introduction The drive to improve outcomes and the inevitability of mandated public reporting necessitate uniform documentation and accurate databases. The reporting of wound classification in patients undergoing hepato-pancreatico-biliary (HPB) surgery and the impact of inconsistencies on quality metrics were investigated. Methods The 2005–2011 National Surgical Quality Improvement Program (NSQIP) participant use file was interrogated to identify patients undergoing HPB resections. The effect of wound classification on post-operative surgical site infection (SSI) rates was determined through logistic regression. The impact of variations in wound classification reporting on perceived outcomes was modelled by simulating observed-to-expected (O/E) ratios for SSI. Results In total, 27 376 patients were identified with significant heterogeneity in wound classification. In spite of clear guidelines prompting at least ‘clean-contaminated’ designation for HPB resections, 8% of all cases were coded as ‘clean’. Contaminated [adjusted odds ratio (AOR): 1.39, P = 0.001] and dirty (AOR: 1.42, P = 0.02] cases were associated with higher odds of SSI, whereas clean-contaminated were not ( P = 0.99). O/E ratios were highly sensitive to modest changes in wound classification. Conclusions Perceived performance is affected by heterogeneous reporting of wound classification. As institutions work to improve outcomes and prepare for public reporting, it is imperative that all adhere to consistent reporting practices to provide accurate and reproducible outcomes.

Die Behandlung lokal fortgeschrittener pelviner Tumoren bedarf in der Regel einer radikalen chirurgischen Resektion. Diese Resektion fuhrt zu erheblichen inneren und auseren Defekten im Bereich des kleinen Beckens. Die Verwendung kombinierter Lappenplastiken hat die vaginale und perineale Rekonstruktion revolutioniert. Derartige Lappenplastiken liefern ausreichend Substanz, um Hohlraume zu fullen, erganzen vaskularisiertes Gewebe in eine vorbestrahlte Umgebung und erleichtern den Wundverschluss. Die Autoren prasentieren einen modifizierten vertikalen Rectus-abdominis-Muskel-Haut (VRAM)-Lappen zur simultanen Rekonstruktion eines Perineum- und posterioren vaginalen Defekts nach radikaler pelviner und abdominoperinealer Resektion. Die Lappenplastik basiert auf zwei unterschiedlichen Perforatoren aus der inferioren epigastrischen Arterie und Vene.

Background Rectourethral fistulas are an uncommon, yet devastating occurrence after treatment for prostate cancer or trauma, and their surgical management has historically been nonstandardized. Anecdotally, irradiated rectourethral fistulas portend a worse prognosis. Objective To review outcomes after surgical treatment of rectourethral fistulas in radiated and nonirradiated patients to construct a logical surgical algorithm. Design and setting A retrospective review was undertaken of all patients presenting to Duke University with the diagnosis of rectourethral fistula from 1996 to 2012. Patients Thirty-seven patients presented with and were treated for rectourethral fistulas: 21 received radiation, and a rectourethral fistula from trauma or iatrogenic injury developed in 16. Main outcome measures The groups were compared regarding their functional outcomes, including healing, time to healing, continence, and recurrence. Results There were no significant differences in patient characteristics between groups. Patients who had irradiated rectourethral fistulas had a significantly higher rate of passage of urine through the rectum and wound infections, a higher rate of crystalloid infusion and blood transfusion requirements, and a longer time to ostomy reversal than nonirradiated patients. Patients who had irradiated rectourethral fistulas underwent more complex operative repairs, including gracilis interposition flaps (38%) and pelvic exenterations (19%), whereas nonirradiated patients most commonly underwent a York-Mason repair (50%). There were no statistically significant differences in rectourethral fistula healing or in postoperative and functional outcomes. Only 55% of irradiated patients had their ostomy reversed versus 91% in the nonirradiated group. Limitations This study was limited by the small sample size and the retrospective nature of the review. Conclusions Repair of rectourethral fistulas caused by radiation has a significantly higher wound infection rate and median time to healing, and lower overall stomal reversal rate than nonradiation-induced rectourethral fistulas. Patients who had irradiated rectourethral fistulas required significantly more complex operations, likely contributing to the higher morbidity, mortality, and lower fistula closure rate. We propose an algorithm for approaching rectourethral fistulas based on etiology.

While the use of laparoscopy has increased among patients undergoing colorectal surgery, there is ongoing debate regarding the oncologic equivalence of laparoscopy compared to open low anterior resection (LAR) for rectal cancer.The 2010-2011 NCDB was queried for patients undergoing LAR for rectal cancer. Subjects were grouped by laparoscopic (LLAR) versus open (OLAR) technique. Baseline characteristics were compared. Subjects were propensity matched, and outcomes were compared between groups.A total of 18,765 patients were identified (34.3% LLAR, 65.7% OLAR). After propensity matching, all baseline variables were highly similar except for carcinoembryonic antigen (CEA) level. Complete resection was more common in patients undergoing LLAR (91.6 vs. 88.9%, p 0.001), and statistically significant benefits were observed for gross, microscopic, and circumferential (1 mm) margins (all p 0.001). There was no difference in median number of lymph nodes obtained (15 vs. 15). Patients undergoing LLAR had shorter lengths of stay (5 vs. 6 days, p 0.001) without a corresponding increase in 30-day readmission rates (6 vs. 7%, p = 0.02).Laparoscopic LAR appears to result in equivalent short-term oncologic outcomes compared to the traditional open approach as measured via surrogate endpoints in the NCDB. While these results support the increasing use of laparoscopy in rectal surgery, further data are necessary to assess long-term outcomes.

Few studies have examined the current status of ureteral stent use or the indications for stenting, particularly in laparoscopic colorectal surgery. This study examines current national trends and predictors of ureteral stenting in patients undergoing major colorectal operations and the subsequent effects on perioperative outcomes.The 2005-2011 National Surgical Quality Improvement participant user files were used to identify patients undergoing laparoscopic segmental colectomy, low anterior resection, or proctectomy. Trends in stent use were assessed across procedure types. To estimate the predictors of stent utilization, a forward-stepwise logistic regression model was used. A 3:1 nearest neighbor propensity match with subsequent multivariable adjustment was then used to estimate the impact of stents.A total of 42,311 cases were identified, of which 1795 (4.2%) underwent ureteral stent placement. Predictors of stent utilization included diverticular disease, need for radical resection (versus segmental colectomy), recent radiotherapy, and more recent calendar year. After adjustment, ureteral stenting appeared to be associated with a small increase in median operative time (44 min) and a trivial increase in length of stay (5.4%, P0.001). However, there were no significant differences in morbidity or mortality.We describe the clinical predictors of ureteral stent usage in this patient population and report that while stenting adds to operative time, it is not associated with significantly increased morbidity or mortality after adjusting for diagnosis and comorbidities. Focused institutional studies are necessary in the future to address the utility of ureteral stents in the identification and possible prevention of iatrogenic injury.

Hand-assisted laparoscopic surgery (HALS) is often used in procedures too complex for completely minimally invasive approaches. However, there are concerns for whether this hybrid approach abrogates perioperative benefits of the completely minimally invasive technique. We queried the 2012–2013 National Surgery Quality Improvement Program for adults undergoing elective HALS or open colectomy (OC). After propensity matching, short-term outcomes were compared. Subset analysis was performed for segmental resections. Multivariate analysis was used to determine predictors of utilizing either approach. This query included 8791 patients (OC 2707, HALS 6084). Predictors of HALS included male sex (OR 1.17, p = 0.006), increasing BMI (OR 1.01, p = 0.02), benign indication (OR 1.48, p

We performed a study to understand common practices in surgical site hair removal and barriers to guideline compliance in surgical site hair removal. We found most health care providers in the United States do not remove hair outside of the operating room. Our findings reveal minimizing hair dispersal in the operating room, including improved and innovative ways for collecting clipped loose hair, is a significant area for improvement in surgical quality and health care–acquired infection prevention.

HAL colectomy is a technique perceived to provide the benefits of laparoscopic surgery while improving tactile feedback and operative time. Published data are largely limited to small, single-institution studies. The 2012-2013 National Surgical Quality Improvement Program Participant Data Use File was queried for patients undergoing elective SL or HAL colectomy. Patients underwent 1:1 propensity matching and had outcomes compared. An additional subgroup analysis was performed for patients undergoing segmental resections only. 13,949 patients were identified, of whom 6084 (43.6 %) underwent HAL colectomy. Patients undergoing HAL versus SL colectomy had higher rates of postoperative ileus (8.7 vs. 6.3 %, p

Interest in robotic technology is burgeoning within the field of colorectal surgery. However, benefits of robotic-assisted colectomy (RAC) compared with laparoscopic colectomy (LC) remain ambiguous.Patients who underwent minimally invasive colectomy during 2012-2013 were identified from the National Surgical Quality Improvement Program (NSQIP) database. Short-term perioperative outcomes were compared between 1:1 propensity-matched groups. A subset analysis was performed among patients who underwent segmental resections.Among the 15,976 patients included, 498 (3.1 %) colectomies were performed with robotic assistance. After matching for demographic, clinical, and treatment characteristics, there were no differences between RAC and LC in complications such as wound infection, urinary tract infection, cardiopulmonary or thromboembolic events, renal insufficiency, anastomotic leaks, transfusions, readmissions, or 30-day mortality (all p 0.05). However, operative time was markedly higher for RAC (196 vs. 166 min, p 0.001). Among segmental resections, operative time remained significantly longer for RAC (190 vs. 153 min, p 0.001) without differences in perioperative outcomes (all p 0.05).In this early experience, RAC resulted in similar perioperative outcomes when compared to LC but was associated with longer operative time. Given the focus on value-based healthcare, utilizing RAC in straightforward colectomies may not be financially justifiable at this stage of adoption.

Limited data exist regarding the effect of conversion from laparoscopic to open colectomy on perioperative and oncologic outcomes in colon cancer.The National Cancer Data Base was used to identify patients who underwent colectomy for non-metastatic colon cancer (2010-2012). Patients were stratified into three groups: laparoscopic/robotic-assisted colectomy (MIC), converted colectomy (CC), and open colectomy (OC). Multivariable modeling was applied to compare outcomes from CC and MIC to OC while adjusting for patient, clinical, and tumor characteristics.Of 104,400 patients, 40,328 (38.6 %) underwent MIC, 57,928 (55.5 %) OC, and 6144 (5.9 %) CC. After adjustment, the rate of positive surgical margins was not significantly different between CC and OC (p = 0.44). However, with adjustment, CC versus OC was associated with shorter hospital length of stay (4 % decrease, 95 % CI 2-5 %, p 0.0001) and lower odds of 30-day mortality (OR 0.77, 95 % CI 0.64-0.94, p = 0.0112). Adjusted overall survival was similar between CC and OC (p = 0.34).Conversion from laparoscopic to open colectomy was not associated with compromised oncologic outcomes, while maintaining improved short-term outcomes despite being attempted in only 45 % of patients. This data suggests that utilization of laparoscopic colectomy should be attempted for patients with colon cancer.

The realm of minimally invasive surgery now encompasses the majority of abdominal operations in the field of colorectal surgery. Diverticulitis, a common pathology seen in most colorectal practices, poses unique challenges to surgeons implementing laparoscopic surgery in their practices due to the presence of an inflammatory phlegmon and distorted anatomical planes, which increase the difficulty of the operation. Although the majority of colon resections for diverticulitis are still performed through a standard laparotomy incision, laparoscopic techniques are becoming increasingly common. A large body of literature now supports laparoscopic surgery to be safe and effective as well as to provide significant advantages over open surgery for diverticular disease. Here, we review the most current literature supporting laparoscopic surgery for elective and emergent treatment of diverticulitis.

Our objective was to review our 10-year experience of surgical resection for acute ischemic colitis (IC) and to assess the predictive value of previously reported risk-stratification methods. We retrospectively reviewed all adult patients at our institution undergoing colectomy for acute IC between 2000 and 2009. Descriptive statistics were calculated. Long-term survival was assessed using Kaplan–Meier methods and in-hospital mortality using multivariate logistic regression. Patients were risk-stratified based on previously reported methods, and discriminatory accuracy of predicting in-hospital mortality was evaluated by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. A total of 115 patients were included for analysis, of which 37 % (n = 43) died in-hospital. The median survival was 4.9 months for all patients and 43.6 months for patients surviving to discharge. Seventeen patients subsequently underwent end-ostomy reversal at our institution, with in-hospital mortality of 18 % (n = 3) and ICU admission for 35 % (n = 6). The discriminatory accuracy of risk stratification in predicting in-hospital mortality based on ROC AUC was 0.75. Acute IC continues to remain a very deadly disease. Patients who survive the initial acute IC insult can achieve long-term survival; however, we experienced high rates of death and complications following elective end-ostomy reversal. Risk stratification provides reasonable accuracy in predicting postoperative mortality.

The aim of this study was to evaluate the efficacy and morbidity of intraoperative radiation therapy (IORT) for advanced colorectal cancer.All patients undergoing IORT for locally advanced rectal cancer from 2001-2009 were reviewed for cancer recurrence, survival, and procedure-related morbidity. Cumulative event rates were estimated using the method of Kaplan and Meier.Twenty-nine patients with locally advanced (n = 8) or recurrent (n = 21) rectal cancers were treated with IORT and resection. Surgical interventions included low anterior resection, abdominoperineal resection, pelvic exenteration, and a variety of non-anatomic resections of pelvic recurrences. R(0) resections were achieved in 16 patients, while R(1) resections were achieved in 10, and margins were grossly positive in 3 patients. IORT was delivered to all patients over a median area of 48 (42-72) cm(2) at a median dose of 12 (12-15) Gy. Local and overall recurrence rates were 24 % (locally advanced group) and 45 % (recurrent group). Median disease-free and overall survival were 25 and 40 months respectively at a median follow-up of 26 (18-42) months. The short-term (≤30 days) complication rate was 45 %. Eight patients developed local wound complications, 5 of which required operative intervention. Four patients developed intra-abdominal abscesses requiring drainage. Long-term (30 days) complications were identified in 11 patients (38 %) and included long-term wound complications (n = 3), ureteral obstruction requiring stenting (n = 1), neurogenic bladder (n = 3), enteric fistulae (n = 2), small bowel obstruction (n = 1), and neuropathic pain (n = 1).Intraoperative brachytherapy is a viable IORT option during pelvic surgery for locally advanced or recurrent colorectal cancer but is associated with high postoperative morbidity. Whether intraoperative brachytherapy can improve local recurrence rates for locally advanced or recurrent colorectal cancer will require further prospective investigation.

The optimal timing of primary and metastatic tumor management in patients with synchronous hepatic colorectal metastases remains controversial. We aimed to compare perioperative outcomes of simultaneous colorectal/liver resection (SCLR) with isolated resections utilizing a national clinical database. NSQIP data from 2005 to 2009 were examined to construct risk-adjusted generalized linear models and to calculate group-specific predicted estimates. These were used to compare 30-day perioperative outcomes among patients undergoing SCLR with colorectal (CR) and liver resections (LR) only in patients with metastatic colorectal cancer. A total of 3,983 patients were identified, who underwent SCLR (192), LR (1,857), or CR (1,934). Rectal resection was performed in 45 (23.4 %) SCLR patients and 269 (13.9 %) CR patients (p
