From the borders edge to the brink of death: A case of a traumatic pancreatic injury and Whipple procedure in the Rio Grande Valley.

The traumatic pancreatoduodenectomy, also known as the traumatic Whipple, is a specialized surgical procedure often reserved for extreme cases in which an individual suffers traumatic injuries to the pancreas, duodenum, or periampullary structures. Traditionally, a Whipple procedure is a complex surgery involving the removal of the head of the pancreas, duodenum, and a portion of both the bile duct and stomach, for the management of pancreatic head cancer. In underserved communities where limited access to healthcare is coupled with a higher incidence of trauma, the lack of specialized and supportive care for patients suffering from pancreatic injuries may lead to an increased morbidity and mortality rate. This case report aims to provide a detailed analysis of a patient who underwent a traumatic pancreatoduodenectomy in a medically underserved region in South Texas, while discussing the rarity of the procedure, its incidence and mortality rates, as well as the subsequent outcomes faced by individuals in this patient population.

Using NSQIP Data to Reduce Institutional Postoperative Pneumonia Rates in Non-ICU Patients: A Plan-Do-Study-Act Approach.

BACKGROUND: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) is a program designed to measure and improve surgical care quality. In 2015, the study institution formed a multidisciplinary team to address the poor adult postoperative pneumonia performance (worst decile). STUDY DESIGN: The study institution is a 450+ bed tertiary care center that performs 12,000+ surgical procedures annually. From January 2016 to December 2019, the institution abstracted surgical cases and assigned postoperative pneumonia as a complication per the NSQIP operations manual. Using a plan-do-study-act approach, a multidisciplinary postoperative pneumonia prevention team implemented initiatives regarding incentive spirometry education, anesthetic optimization, early mobility, and oral care. The team measured the initiatives' success by analyzing semiannual reports (SAR) provided by the ACS NSQIP and regional adjusted percentile rankings provided by the Georgia Surgical Quality Collaborative (GSQC). RESULTS: The 2015 SAR postoperative pneumonia rate was 4.20% (odds ratio [OR] 3.86, confidence interval [CI] 2.92-5.11). After project initiation, the postoperative pneumonia rates decreased for all NSQIP cases, from 2.51% (OR 2.67, CI 1.89-3.77) in 2016 to 2.08% (OR 2.61, CI 1.82-3.74) in 2017, to 0.85% (OR 1.10, CI 0.69-1.75) in 2018, and then increased slightly to 1.14% (OR 1.27, CI 0.84-1.92) in 2019. The institution's adjusted percentile regional rank of participating regional ACS NSQIP hospitals' postoperative pneumonia rate improved from 14/14 (July 2015-June 2016) to 6/14 (July 2018-June 2019). CONCLUSIONS: The multidisciplinary postoperative pneumonia prevention team successfully decreased the postoperative pneumonia rate, therefore improving surgical patients' outcomes. Furthermore, this quality improvement project also saved valuable revenue for the hospital.

A chemokine/chemokine receptor signature potentially predicts clinical outcome in colorectal cancer patients.

BACKGROUND: Differential expression of chemokines/chemokine receptors in colorectal cancer (CRC) may enable molecular characterization of patients' tumors for predicting clinical outcome. OBJECTIVE: To evaluate the prognostic ability of these molecules in a CRC cohort and the CRC TCGA-dataset. METHODS: Chemokine (CXCL-12α, CXCL-12ß, IL-17A, CXCL-8, GM-CSF) and chemokine receptor (CXCR-4, CXCR-7) transcripts were analyzed by RT-qPCR in 76 CRC specimens (normal: 27, tumor: 49; clinical cohort). RNA-Seq data was analyzed from the TCGA-dataset (n= 375). Transcript levels were correlated with outcome; analyses: univariate, multivariable, Kaplan-Meier. RESULTS: In the clinical cohort, chemokine/chemokine receptor levels were elevated 3-10-fold in CRC specimens (P⩽ 0.004) and were higher in patients who developed metastasis (P= 0.03 - < 0.0001). CXCR-4, CXCR-7, CXCL-12α, CXCL-8, IL-17 and GM-CSF levels predicted metastasis (P⩽ 0.0421) and/or overall survival (OS; P⩽ 0.0373). The CXCR-4+CXCR-7+CXCL-12 marker (CXCR-4/7+CXCL-12 (α/b) signature) stratified patients into risk for metastasis (P= 0.0014; OR, 2.72) and OS (P= 0.0442; OR, 2.7); sensitivity: 86.67%, specificity: 97.06%. In the TCGA-dataset, the CXCR-4/7+CXCL-12 signature predicted metastasis (P= 0.011; OR, 2.72) and OS (P= 0.0006; OR: 4.04). In both datasets, the signature was an independent predictor of clinical outcome. CONCLUSIONS: Results of 451 specimens from both cohorts reveal that the CXCR-4/7+CXCL-12 signature potentially predicts outcome in CRC patients and may allow earlier intervention.

Financial Analysis of Free Lung Cancer Screening Program Shows Profitability Using Broader NCCN Guidelines.

BACKGROUND: Lung cancer screening with low-dose computed tomography (LDCT) chest scans in high-risk populations has been established as an effective measure of preventive medicine by the National Lung Screening Trial. However, the sustainability of funding a program is still controversial. We present a 2.5-year profitability analysis of our screening program by using the broader National Comprehensive Cancer Network criteria. METHODS: Retrospective chart review was performed on the initial 2.5-year data set of a free LDCT chest scan program that targeted the underserved Southeastern United States. Patients were selected by the National Comprehensive Cancer Network high-risk criteria, screening twice as many patients compared with Centers for Medicare and Medicaid Services criteria. LDCT scans were performed during the off-service hours of our positron emission tomography CT scanner. Analysis of fiscal years 2015 to 2017 was done to evaluate indirect cost, direct cost, and adjusted net margin per case after factoring downstream revenue from positive scans and other findings. RESULTS: A total of 705 scans were performed with 418 patients referred for subsequent procedures or specialist evaluations. The mean overhead cost over total cost was 42.3%. The adjusted net margin per case was -$212 in the first year but turned positive to $177 in the third fiscal year. The total break-even point of adjusted net margin was between 6% and 7% of indirect cost as a function of charges. Of the 60 new patients introduced to the hospital system, a gross margin per case of $211 was found. CONCLUSIONS: Free lung cancer screening can demonstrate profitability from downstream revenue with a lag time of 2 years.

Ileostomy creation in colorectal cancer surgery: risk of acute kidney injury and chronic kidney disease.

BACKGROUND: Ileostomy creation is associated with postoperative dehydration and readmission; however, the effect on renal function is unknown. Our goal was to characterize the impact of ileostomy creation on acute and chronic renal function. MATERIALS AND METHODS: A retrospective cohort study with patients undergoing colorectal cancer surgery at a tertiary referral institution (2005-2011). The relationship between ileostomy creation and acute kidney injury (AKI)-related readmission, severe chronic kidney disease (CKD) at 12 mo (glomerular filtration rate <30 mL/min/1.73 m2), and onset of severe CKD over time was evaluated using multivariable logistic and Cox regression and adjusted using propensity score stratification. RESULTS: Among 619 patients, 84 (13%) had ileostomy. AKI-related readmission and severe CKD at 12 mo were more common among ileostomy patients (17% versus 2%, P < 0.01 and 13.3% versus 5%, P = 0.02, respectively). After propensity score adjustment, ileostomy was a significant predictor of AKI-related readmissions (odds ratio: 10.3; 95% confidence interval [CI], 3.9-27.2), severe CKD at 12 mo (odds ratio: 4.1; 95% CI, 1.4-11.9), and onset of severe CKD over time (hazard ratio: 4.2; 95% CI, 2.3-6.6). CONCLUSIONS: Ileostomy creation is associated with increased risk of AKI-related readmissions and development of severe CKD. Future studies must focus on strategies to minimize kidney injury when ileostomy is a necessary component of colorectal cancer surgery and revisiting current indications for ileostomy creation.

Patterns of Care for Colorectal Liver Metastasis Within an Integrated Health System: Secular Trends and Outcomes.

BACKGROUND: Utilization of evidence-based treatments for patients with colorectal liver metastasis (CRC-LM) outside high-volume centers is not well-characterized. We sought to describe trends in treatment and outcomes, and identify predictors of therapy within a nationwide integrated health system. METHODS: Observational cohort study of patients with CRC-LM treated within the Veterans Affairs (VA) health system (1998-2012). Secular trends and outcomes were compared on the basis of treatment type. Multivariate regression was used to identify predictors of no treatment (chemotherapy or surgery). RESULTS: Among 3270 patients, 57.3 % received treatment (chemotherapy and/or surgery) during the study period. The proportion receiving treatment doubled (38 % in 1998 vs. 68 % in 2012; trend test, p < 0.001), primarily driven by increased use of chemotherapy (26 vs. 57 %; trend test, p < 0.001). Among patients having surgery (16 %), the proportion having ablation (10 vs. 61.9 %; trend test, p < 0.001) and multimodality therapy (15 vs. 67 %; trend test, p < 0.001) increased significantly over time. Older patients [65-75 years: odds ratio (OR) 1.65, 95 % confidence interval (CI) 1.39-1.97; >75 years: OR 3.84, 95 % CI 3.13-4.69] and those with high comorbidity index (Charlson ≥3: OR 1.47, 95 % CI 1.16-1.85) were more likely to be untreated. Overall survival was significantly different based on treatment strategy (log-rank p < 0.001). CONCLUSIONS: The proportion of CRC-LM patients receiving treatment within the largest integrated health system in the US (VA health system) has increased substantially over time; however, one in three patients still does not receive any treatment. Future initiatives should focus on increasing treatment among older patients as well as on evaluating reasons leading to the no-treatment approach and increased use of ablation procedures.

Racial disparities in the use of laparoscopic surgery to treat colonic diverticulitis Are not fully explained by socioeconomics or disease complexity.

BACKGROUND: Several studies have demonstrated favorable outcomes for laparoscopic surgery over open surgery for the treatment of diverticular disease. This study was designed to analyze the relationship between race, socioeconomic status and the use of laparoscopy to address diverticulitis. METHODS: A retrospective analysis of 53,054 diverticulitis admissions was performed using data from the 2009-2013 National Inpatient Sample (NIS). The primary outcome was the use of laparoscopic versus open colectomy. Bivariate analysis and multivariable logistic regression were used to determine the raw and adjusted odds by race, insurance status, and median household income. RESULTS: Overall, 41.6% of colectomies involved the use of laparoscopy. Black patients were 19% less likely than White patients to undergo laparoscopic surgery. Hispanic patients were no more or less likely to undergo laparoscopic colectomy. Lacking private insurance was a strong predictor of undergoing open surgery. Lower income patients were 33% less likely to receive minimally invasive colectomies. CONCLUSIONS: These results demonstrate disparities in surgical treatment. Further research is warranted to understand and ameliorate treatment differences which can contribute to outcome disparities.

Ninety-day readmission after colorectal cancer surgery in a Veterans Affairs cohort.

BACKGROUND: Readmissions following colorectal surgery are common. However, there are limited data examining unplanned readmissions (URs) after colorectal cancer (CRC) surgery. The goal of this study was to identify reasons and predictors of UR, and to examine their clinical impact on CRC patients. METHODS: A retrospective cohort study using a prospective CRC surgery database of patients treated at a VA tertiary referral center was performed (2005-2011). Ninety-day URs were recorded and classified based on reason for readmission. Clinical impact of UR was measured using a validated classification for postoperative complications. Multivariate logistic regression analyses were performed to identify predictors of UR. RESULTS: 487 patients were included; 104 (21%) required UR. Although the majority of UR were due to surgical reasons (n = 72, 69%), medical complications contributed to 25% of all readmission events. Nearly half of UR (n = 44, 40%) had significant clinical implications requiring invasive interventions, intensive care unit stays, or led to death. After multivariate logistic regression, the following independent predictors of UR were identified: African-American race (odds ratio [OR] 0.47 [0.27-0.88]), ostomy creation (OR 2.50 [1.33-4.70]), and any postoperative complication (OR 4.36 [2.48-7.68]). CONCLUSIONS: Ninety-day URs following colorectal cancer surgery are common, and represent serious events associated with worse outcomes. In addition to postoperative complications, surgical details that can be anticipated (i.e., ileostomy creation) and medical events unrelated to surgery, both contribute as important and potentially preventable reasons for UR. Future studies should focus on developing and examining interventions focused at improving the process of perioperative care for this high-risk population.

Sphincter preservation rates after radical resection for rectal cancer in the United States veteran population: opportunity for improvement in early disease.

BACKGROUND: Sphincter preservation (SP) is an important goal of rectal cancer surgery. We hypothesized that SP rates among veteran patients have increased and are comparable to national rates, and that a subset of patients with early disease still undergo non-SP procedures. METHODS: Patients with nonmetastatic primary rectal adenocarcinoma who underwent curative-intent rectal resection were identified from the Veterans Affairs Central Cancer Registry (VACCR) database (1995-2010). SP trends over time were described and compared to the Surveillance, Epidemiology, and End-Results (SEER) population. Subset analysis was performed in patients with nonirradiated, pathologic stage 0-I rectal cancers, a population that may qualify for novel SP strategies. RESULTS: Of 5,145 study patients, 3,509 (68 %) underwent SP surgery. The VACCR SP rate increased from 59.9 % in 1995-1999 to 79.3 % in 2005-2010, when it exceeded that of SEER (76.9 %, p = 0.023). On multivariate analysis, recent time period was independently associated with higher likelihood of SP (odds ratio [OR] 2.64, p < 0.001). Preoperative radiotherapy (OR 0.51, p < 0.001) and higher pathologic stage (OR 0.37, stage III, p < 0.001) were negative predictors. In patients with nonirradiated pathologic stage 0-I cancers, SP rates also increased, but 25 % of these patients underwent non-SP procedures. Within this subset, patients with clinical stage 0 and I disease still had significant rates of abdominoperineal resection (7.7 and 17.0 %, respectively). CONCLUSIONS: SP rates among veterans have increased and surpass national rates. However, an unacceptable proportion of patients with stage 0-I rectal cancers still undergo non-SP procedures. Multimodal treatment with local excision may further improve SP rates in this subset of patients.

Postoperative transitional care needs in the elderly: an outcome of recovery associated with worse long-term survival.

OBJECTIVE: To characterize transitional care needs (TCNs) after colorectal cancer (CRC) surgery and examine their association with age and impact on overall survival (OS). BACKGROUND: TCNs after cancer surgery represent additional burden for patients and are associated with higher short-term mortality. They are not well-characterized in CRC patients, particularly in the context of a growing elderly population, and their effect on long-term survival is unknown. METHODS: A retrospective cohort study of CRC patients (N = 486) having curative surgery at a tertiary referral center (2002-2011) was conducted. Outcomes included TCNs (home health or nonhome destination at discharge) and OS. Patients were compared on the basis of age: young (<65 years), old (65-74 years), and oldest (≥75 years). Multivariate logistic regression models were used to examine the association of age with TCNs, and OS was compared on the basis of TCNs and stage, using the Kaplan-Meier method. RESULTS: TCNs were required by 130 patients (27%). The oldest patients had highest TCNs (49%) compared with the other age groups (P < 0.01), with rehabilitation services as their primary TCNs (80%). After multivariate analysis, patients 75 years or older had significantly increased TCN risk (odds ratio, 4.7; 95% confidence interval, 2.6-8.5). TCN was associated with worse OS for patients with early- and advanced stage CRC (P < 0.001). CONCLUSIONS: TCNs after CRC surgery are common and significantly increased in patients 75 years or older, represent an outcome of postoperative recovery, and are associated with worse long-term survival. Preoperative identification of higher risk populations should be used for patient counseling, advanced preoperative planning, and to implement strategies targeted at minimizing TCNs.

The effect of a regional hepatopancreaticobiliary surgical program on clinical volume, quality of cancer care, and outcomes in the Veterans Affairs system.

IMPORTANCE: Malignant neoplasms of the hepatopancreaticobiliary (HPB) system constitute a significant public health problem worldwide. Treatment coordination for these tumors is challenging and can result in substandard care. Referral centers for HPB disease have been used as a strategy to improve postoperative outcomes, but their effect on accomplishing regionalization of care and improving quality of cancer care is not well known. OBJECTIVE: To evaluate the effect of implementing a multidisciplinary HPB surgical program (HPB-SP) on regionalization of care, the quality of cancer care, and surgical outcomes within an integrated health care system. DESIGN, SETTING, AND PARTICIPANTS: We designed a retrospective cohort study in a tertiary referral Veterans Affairs (VA) medical center within an 8-state designated VA health care region from November 23, 2005, through December 31, 2013. We compared patients with HPB tumors undergoing evaluation by the surgical oncology service before and after implementation of the HPB-SP on November 1, 2008. EXPOSURES: Implementation of the HPB-SP to improve access to specialized, multidisciplinary cancer care for veterans across the region. MAIN OUTCOMES AND MEASURES: Clinical and surgical volume, proportion of patients undergoing a comprehensive multidisciplinary evaluation, and postoperative adverse events included as a composite outcome defined by occurrence of postoperative mortality, severe complications, and/or reoperation. RESULTS: We identified 516 patients referred to the surgical oncology service. Establishment of the HPB-SP resulted in significant increases in regional referrals (17.3% vs 44.4%; P < .001), median monthly clinic visits (5 vs 20; P < .001), and median number of HPB surgical procedures (3 vs 9; P = .003) per quarter. Multidisciplinary assessment increased from 52.6% to 70.0% (P < .001). When we compared patients with hepatocellular carcinoma before (n = 55) and after (n = 131) implementation, more patients received any treatment (35 [63.6%] vs 109 [83.2%]; P = .004) with increased use of liver resection (0 vs 20 [15.3%]; P = .002), percutaneous ablation (0 vs 15 [11.5%]; P = .009), and oncosurgical strategies (0 vs 16 [12.2%]; P = .007) after implementation. Among patients with colorectal liver metastases (29 before vs 76 after implementation), a significant shift occurred from use of ablations (5 [17.2%] vs 3 [3.9]%; P = .02) to resections (6 [20.7%] vs 40 [52.6%]; P = .003), and use of perioperative chemotherapy increased (5 of 11 [45.5%] vs 33 of 43 [76.7%]; P = .01). The HPB-SP was associated with lower odds of postoperative adverse events, even after adjusting for important covariates (odds ratio, 0.29 [95% CI, 0.12-0.68]; P = .005), and a high rate of margin-negative liver (94.6%) and pancreatic (90.0%) resections. CONCLUSIONS AND RELEVANCE: The development of an HPB-SP led to regionalization of care and improved quality of cancer care and surgical outcomes. Establishment of regional programs within the VA system can help improve the quality of care for patients presenting with complex cancers requiring subspecialized care.

Implementation of a regional virtual tumor board: a prospective study evaluating feasibility and provider acceptance.

BACKGROUND: Tumor board (TB) conferences facilitate multidisciplinary cancer care and are associated with overall improved outcomes. Because of shortages of the oncology workforce and limited access to TB conferences, multidisciplinary care is not available at every institution. This pilot study assessed the feasibility and acceptance of using telemedicine to implement a virtual TB (VTB) program within a regional healthcare network. MATERIALS AND METHODS: The VTB program was implemented through videoconference technology and electronic medical records between the Houston (TX) Veterans Affairs Medical Center (VAMC) (referral center) and the New Orleans (LA) VAMC (referring center). Feasibility was assessed as the proportion of completed VTB encounters, rate of technological failures/mishaps, and presentation duration. Validated surveys for confidence and satisfaction were administered to 36 TB participants to assess acceptance (1-5 point Likert scale). Secondary outcomes included preliminary data on VTB utilization and its effectiveness in providing access to quality cancer care within the region. RESULTS: Ninety TB case presentations occurred during the study period, of which 14 (15%) were VTB cases. Although one VTB encounter had a technical mishap during presentation, all scheduled encounters were completed (100% completion rate). Case presentations took longer for VTB than for regular TB cases (p=0.0004). However, VTB was highly accepted with mean scores for satisfaction and confidence of 4.6. Utilization rate of VTB was 75%, and its effectiveness was equivalent to that observed for non-VTB cases. CONCLUSIONS: Implementation of VTB is feasible and highly accepted by its participants. Future studies should focus on widespread implementation and validating the effectiveness of this model.

Laparoscopic versus robotic rectal resection for rectal cancer in a veteran population.

BACKGROUND: Robotic rectal cancer resection remains controversial. We compared the safety and efficacy of laparoscopic vs robotic rectal cancer resection in a high-risk Veterans Health Administration population. METHODS: Patients who underwent minimally invasive rectal cancer resection were identified from an institutional colorectal cancer database. Baseline characteristics and outcomes were compared between robotic and laparoscopic groups. RESULTS: The robotic group (n = 13) did not differ significantly from the laparoscopic group (n = 59) with respect to baseline characteristics except for a higher rate of previous abdominal surgery. Robotic patients had significantly lower tumors, more advanced disease, a higher rate of preoperative chemoradiation, and were more likely to undergo abdominoperineal resection. Robotic rectal resection was associated with longer operative time. There were no differences in blood loss, conversion rates, postoperative morbidity, lymph nodes harvested, margin positivity, or specimen quality between groups. CONCLUSIONS: The robotic approach for rectal cancer resection is safe with similar postoperative and oncologic outcomes compared with laparoscopy.

Postoperative mortality and need for transitional care following liver resection for metastatic disease in elderly patients: a population-level analysis of 4026 patients.

OBJECTIVES: The goal of this study was to characterize the association of age with postoperative mortality and need for transitional care following hepatectomy for liver metastases. METHODS: A retrospective cohort study using the Nationwide Inpatient Sample (2005-2008) was performed. Patients undergoing hepatectomy for liver metastases were categorized by age as: Young (aged <65 years); Old (aged 65-74 years), and Oldest (aged ≥75 years). Multivariate logistic regression analyses were performed to identify predictors of in-hospital mortality and need for transitional care (non-home discharge). RESULTS: A total of 4026 patients were identified; 36.6% (n = 1475) were elderly (aged ≥65 years). Rates of in-hospital mortality and non-home discharge increased with advancing age group [1.3% vs. 2.2% vs. 3.3% (P = 0.005) and 2.1% vs. 6.1% vs. 18.3% (P < 0.001), respectively]. Independent predictors of in-hospital mortality were age within the Oldest category [odds ratio (OR) 2.21, 95% confidence interval (CI) 1.19-4.12] and a Deyo Comorbidity Index score of ≥3 (OR 6.95, 95% CI 3.55-13.60). Independent predictors for need for transitional care were age within the Old group (OR 2.44, 95% CI 1.66-3.58), age within the Oldest group (OR 8.48, 95% CI 5.87-12.24), a Deyo score of 1 (OR 2.00, 95% CI 1.40-2.85), a Deyo score of 2 (OR 4.70, 95% CI 2.93-7.56), a Deyo score of ≥3 (OR 6.41, 95% CI 3.67-11.20), and female gender (OR 1.56, 95% CI 1.15-2.11). CONCLUSIONS: Although increasing age was associated with higher risk for in-hospital mortality, the absolute risk was low and within accepted ranges, and comorbidity was the primary driver of mortality. Conversely, need for transitional care was significantly more common in elderly patients. Therefore, liver resection for metastases is safe in well-selected elderly patients, although consideration should be made for potential transitional care needs.

Hand-assisted laparoscopy leads to efficient colorectal cancer surgery.

BACKGROUND: Laparoscopic-assisted (LA) colorectal resections have improved short-term outcomes compared with open resections. Lack of tactile feedback, though, has led to lengthy operations and high conversion rates with attendant adverse effects on patients. Hand-assisted laparoscopy (HAL), in contrast, provides tactile feedback while still being minimally invasive. We hypothesize that HAL compared with LA for colorectal cancer resections will be associated with lower conversion rates and decreased operative times, without compromising the advantages of laparoscopy. MATERIALS AND METHODS: We performed a retrospective case-matched study of patients undergoing LA or HAL colorectal cancer resections from 2002 to 2010, using a prospectively maintained colorectal cancer database at a Veterans Affairs Medical Center. Short-term outcomes analyzed (using the Wilcoxon signed rank and McNemar's tests) included operative and perioperative variables and surrogate markers of adequacy of oncologic care. RESULTS: Forty-seven LA patients were matched 1:1 by age and resection with 47 HAL patients. Patients in the HAL group had significantly lower blood loss (100 versus 150 cc, P = 0.04), operative times (206 versus 252 min, P = 0.002), and conversion rates (6% versus 38%, P < 0.0005). They also spent fewer days in the intensive care unit (0 versus 1, P = 0.004) and had quicker return of flatus (3 versus 4 d, P = 0.03). HAL resulted in more lymph nodes resected (21 versus 15, P = 0.03) and a more adequate lymph node harvest (98% versus 77%, P = 0.01). CONCLUSIONS: HAL is associated with improved operative efficiency, conversion rates, and lymphadenectomy as compared with LA colorectal cancer resections. HAL should be considered in the management of colorectal cancer patients.

A stepwise approach to transanal endoscopic microsurgery for rectal cancer using a single-incision laparoscopic port.

BACKGROUND: Radical rectal resection with total mesorectal excision is the current standard of care for the operative treatment of rectal cancer. Local excision is an acceptable alternative in selected patients with early disease (T(is)0-T(1)) and low-risk features, in whom radical resection may be associated with unacceptably high morbidity. With recent data demonstrating favorable results in well-selected patients, the role of local excision for rectal cancer is expanding.1 (,) 2 Transanal endoscopic microsurgery (TEM), which requires the use of an operating anoscope, has been used for the local excision of mid-upper rectal tumors. We describe an alternative approach to TEM for rectal cancer. METHODS: We present a stepwise technique for TEM using a single-incision laparoscopic (SILS) port. The patient is a 64 year-old male with a right anterolateral rectal polyp 7 cm from the anal verge, which on snare polypectomy demonstrated in-situ carcinoma with positive margins. Endoscopic ultrasound demonstrated uT(1) disease with no lymphadenopathy. He opted for local excision and underwent TEM. Our stepwise approach includes: (1) delineation of excision margins, (2) full thickness incision of the rectal wall, (3) circumferential dissection, and full thickness excision, and (4) suture repair. RESULTS: The procedure was performed without intraoperative or postoperative complications. Final pathology revealed in-situ carcinoma with widely negative margins. At 1- and 3-week follow-up visits, the patient was pain free with normal bowel activity and no rectal bleeding or genitourinary dysfunction. DISCUSSION: TEM using a SILS port is an effective technique for the local excision of mid-upper rectal cancer in well-selected patients.

Clinical outcomes of oncologic gastrointestinal resections in patients with cirrhosis.

BACKGROUND: Cirrhosis is a risk factor for postoperative morbidity and mortality after general surgical procedures. However, the impact of cirrhosis on outcomes of surgical resection for gastrointestinal (GI) malignancies has not been described. The authors' objective was to characterize early postoperative and transitional outcomes in cirrhotic patients undergoing GI cancer surgery. METHODS: Query of the National Inpatient Sample Database (2005-2008) identified 106,729 patients who underwent resection for GI malignancy; 1479 (1.4%) had cirrhosis. The association of cirrhosis with postoperative outcomes was examined. The primary outcome measure was in-hospital mortality. Secondary outcomes included length-of-stay (LOS) and discharge to long-term care facility (LTCF). RESULTS: Cirrhotic patients had higher risk of in-hospital mortality (8.9% vs 2.8%, P < .001), longer LOS (11.5 ± 0.26 vs 10.0 ± 0.03 days, P < .001), and higher rate of discharge to LTCF (19.0% vs 15.7%, P < .001). Mortality was highest in patients with moderate to severe liver dysfunction (21.5% vs 6.5%, P < .001). On multivariate analysis, cirrhosis was an independent predictor of in-hospital mortality (odds ratio [OR], 3.0; 95% confidence interval [CI] 2.5-3.7) and nonhome discharge (OR, 1.7; 95% CI, 1.4-2.0). In cirrhotic patients, moderate to severe liver dysfunction was the only independent predictor of in-hospital mortality (OR, 4.03; 95% CI, 2.7-5.9), but did not predict discharge disposition. CONCLUSIONS: Resection of GI malignancy in cirrhotics is associated with poor early postoperative and transitional outcomes, with severity of liver disease being the primary determinant of postoperative mortality. These data suggest that GI cancer operations can be performed safely in well-selected cirrhotic patients with mild liver dysfunction.

Minimally invasive surgery in colon cancer patients leads to improved short-term outcomes and excellent oncologic results.

BACKGROUND: Minimally invasive surgery (MIS) techniques are beneficial compared with open techniques. There is a paucity of data of the potential advantages of MIS in colon cancer surgery for veterans. Therefore, we hypothesize that use of MIS in colon cancer resections in a Veterans Affairs Medical Center will lead to improved short-term outcomes without compromising oncologic outcomes. METHODS: A retrospective analysis of a prospectively maintained database was performed. We compared surgical, short-term, and oncologic outcomes in MIS versus open surgery. RESULTS: MIS patients had significantly less blood loss, surgical time, days to return of bowel function, and hospital and intensive care unit stays. Also, they had a greater and more adequate lymphadenectomy, and were less likely to experience a postoperative complication. Survival analyses showed no difference in overall and disease-free survival. CONCLUSIONS: The use of MIS in colon cancer leads to improved short-term outcomes and similar oncologic outcomes when compared with open surgery.

A multidisciplinary cancer center maximizes surgeons' impact.

BACKGROUND: Colorectal cancer patients require care across different disciplines. Integration of multidisciplinary care is critical to accomplish excellent oncologic results. We hypothesized that the establishment of a dedicated colorectal cancer center (CRCC) around specialty-trained surgeons will lead to increased multidisciplinary management and improved outcomes in colorectal cancer patients. METHODS: We analyzed data from three periods: a baseline group, a period after the recruitment of specialty-trained surgeons, and a period after the creation of a dedicated multidisciplinary cancer center. Data analyzed included surrogate markers of surgical oncologic care, multidisciplinary integration, and oncologic outcomes. RESULTS: Recruitment of specialized surgeons led to improvements in surgical oncologic care; the establishment of the CRCC resulted in further improvements in surgical oncologic care and multidisciplinary integration. CONCLUSION: Our study suggests that although the recruitment of specialty-trained surgeons in a high volume center leads to improvement in surgical oncologic care, it is the establishment of a multidisciplinary center around the surgeons that leads to integrated care and improvements in oncologic outcomes.
