INTRODUCTION: An IPAA is the preferred operative approach for restoration of intestinal continuity in patients with ulcerative colitis and familial adenomatous polyposis. As minimally invasive approaches have become more widely adopted, their use in IPAA has also become increasingly commonplace. Laparoscopy has the same limitations during the proctectomy portion as seen in operations for rectal cancer, including dissection in the mid-to-lower rectum attributed to angles created by bony confines of the deep pelvis and lack of visibility when constructing the anastomosis. Robotic surgery provides improved 3-dimensional and high-definition visualization of the pelvis and multiple degrees of freedom, which greatly enhance performance during the proctectomy and construction of the anastomosis. TECHNIQUE: In the setting of a previous subtotal colectomy, the ileostomy site is taken down and stapled across. A 15-mm balloon trocar is placed in the site to achieve insufflation, and the robotic ports are placed horizontally just above the umbilicus. The lateral mesenteric attachments are mobilized laparoscopically, then the J-pouch is constructed through the ostomy site. The J-pouch is placed back into the abdomen with the anvil in place, and the proctectomy is performed after docking the robot. The rectum is stapled with the robotic stapler and exteriorized from the ileostomy site, and the anastomosis is constructed under direct robotic visualization. RESULTS: In addition to the potential ergonomic advantages, the maneuverability and visualization in the pelvis during the proctectomy and construction of the anastomosis are reported by many surgeons to be improved as compared with laparoscopy, especially in male or obese patients. CONCLUSIONS: A robotic approach during the proctectomy and IPAA offers significant advantages to a laparoscopic approach, expanding our armamentarium of minimally invasive surgical techniques to IPAA.

Background: Palliative care has been increasingly recognized as an important part of cancer care but remains underutilized in patients with solid cancers. There is a current gap in knowledge regarding why palliative care is underutilized nationwide. Objective: To identify the factors associated with palliative care use among deceased patients with solid cancer tumors. Methods: Using the 2016 National Cancer Data Base, we identified deceased patients (2004-2013) with breast, colon, lung, melanoma, and prostate cancer. Data were described as percentages. Associations between palliative care use and patient, facility, and geographic characteristics were evaluated through multivariate logistic regression. Results: A total of 1 840 111 patients were analyzed; 9.6% received palliative care. Palliative care use was higher in the following patient groups: survival >24 months (17% vs 2%), male (54% vs 46%), higher Charlson-Deyo comorbidity score (16% vs 8%), treatment at designated cancer programs (74% vs 71%), lung cancer (76% vs 28%), higher grade cancer (53% vs 24%), and stage IV cancer (59% vs 13%). Patients who lived in communities with a greater percentage of high school degrees had higher odds of receiving palliative care; Central and Pacific regions of the United States had lower odds of palliative care use than the East Coast. Patients with colon, melanoma, or prostate cancer had lower odds of palliative care than patients with breast cancer, whereas those with lung cancer had higher odds. Conclusions: Palliative care use in solid cancer tumors is variable, with a preference for patients with lung cancer, younger age, known insurance status, and higher educational level.

Abstract Background The prognostic value of pathological lymph node status following neoadjuvant radiotherapy (ypN) remains unclear. This study was designed to determine whether ypN status predicted overall survival. Methods Patients with locally advanced rectal adenocarcinoma who underwent neoadjuvant long-course radiation between 2005 and 2014 were identified from the National Cancer Data Base, and divided into ypN0, ypN1 and ypN2 groups. The primary outcome was overall survival. Univariable and multivariable analyses were used to determine factors associated with overall survival. Results Of 12 271 patients, 3713 (30·3 per cent) were found to have residual nodal positivity. A majority of patients with ypN1 (1663 of 2562) and ypN2 (878 of 1151) disease had suspected lymph node-positive disease before neoadjuvant therapy, compared with 3959 of 8558 with ypN0 tumours (P < 0·001). Moreover, ypN1 and ypN2 were significantly associated with ypT3–4 disease (65·7 and 83·0 per cent respectively versus 39·4 per cent for ypN0; P < 0·001). In unadjusted analyses, survival differed significantly between ypN groups (P < 0·001). Five-year survival rates were 81·6, 71·3 and 55·0 per cent for patients with ypN0, ypN1 and ypN2 disease respectively. After adjustment for confounding variables, ypN1 and ypN2 remained independently associated with overall survival: hazard ratio (HR) 1·61 (95 per cent c.i. 1·46 to 1·77) and 2·63 (2·34 to 2·95) respectively (P < 0·001). Overall survival was significantly longer in patients with ypN1–2 combined with ypT0–2 status than among those with ypT3–4 tumours even with ypN0 status (P = 0·031). Clinical nodal status before neoadjuvant therapy was not significantly associated with overall survival (HR 1·05, 0·97 to 1·13; P = 0·259). Conclusion Both ypT and ypN status is of prognostic significance following neoadjuvant therapy for rectal cancer.

Purpose. Multimodal analgesia is an essential component of an enhanced recovery pathway (ERP). An ERP that includes the use of single-injection intrathecal analgesia (IA) has been shown to decrease morbidity and cost and shorten length of stay (LOS). Limited data exist on safety, feasibility, and the optimal IA regimen. Our objective was to characterize the efficacy, safety, and feasibility of IA within an ERP in a cohort of colorectal surgical patients. Methods. We performed a retrospective review of all consecutive patients aged ≥ 18 years who underwent open or minimally invasive colorectal surgery from October 2012 to December 2013. All patients were enrolled in an institutional ERP that included the use of single-injection IA. Demographics, anesthetic management, efficacy (pain scores and opiate consumption), postoperative ileus (POI), adverse effects, and LOS are reported. Results. 601 patients were identified. The majority received opioid-only IA (91%) rather than a multimodal regimen. Median LOS was 3 days. Overall rate of ileus was 16%. Median pain scores at 4, 8, 16, 24, and 48 hours were 3, 2, 3, 4, and 3, respectively. There was no difference in postoperative pain scores, LOS, or POI based on intrathecal medication or dose received. Overall, development of respiratory depression (0.2%) or pruritus (1.2%) was rare. One patient required blood patch for postdural headache. Conclusion. Intrathecal analgesia is safe, feasible, and efficacious in the setting of ERP for colorectal surgery. All regimens and doses achieved a short LOS, low pain scores, and a low incidence of POI. This trial is registered with Clinicaltrails.gov NCT03411109.

BACKGROUND: Clinical trials demonstrate that postresection chemotherapy conveys survival benefit to patients with stage III colon cancer. It is unclear whether this benefit can be extrapolated to the elderly, who are underenrolled in clinical trials. OBJECTIVE: The purpose of this study was to determine outcomes of selected octogenarians with stage III colon cancer with/without postresection adjuvant therapy. DESIGN: This was a retrospective cohort study (2006–2011) using unadjusted Kaplan–Meier and adjusted Cox proportional hazards analyses of overall survival. SETTING: The study was conducted with the National Cancer Database. PATIENTS: We included patients 80 to 89 years of age who were undergoing curative-intent surgery for stage III colon cancer and excluded patients who received neoadjuvant therapy, died within 6 weeks of surgery, or had high comorbidity. MAIN OUTCOME MEASURES: Overall survival was the main measure. RESULTS: A total of 8141 octogenarians were included; 3483 (42.8%) received postresection chemotherapy, and 4658 (57.2%) underwent surgery alone. Patients receiving chemotherapy were younger (82.0 vs 84.0 years; p < 0.001), healthier (73.1% vs 70.4% with no comorbidities; p = 0.009), and more likely to have N2 disease (40.4% vs 32.8%; p < 0.001). Overall survival was improved in patients receiving adjuvant chemotherapy (median = 61.7 vs 35.0 months; p < 0.001). Subgroup analysis of patients offered chemotherapy but refusing (n = 1315) demonstrated overall survival worse than those receiving adjuvant chemotherapy (median = 42.7 vs 61.7 months; p < 0.001). Multivariable analysis adjusting for potential confounders showed therapy with surgery alone to be independently associated with increased mortality hazard (HR = 1.83; p < 0.001), and the mortality hazard remained elevated in patients who voluntarily refused adjuvant therapy (HR = 1.45; p < 0.001). LIMITATIONS: The study was limited by its retrospective, nonrandomized design. CONCLUSIONS: In selected octogenarians with stage III colon cancer, postresection adjuvant chemotherapy was associated with superior overall survival. However, less than half of the octogenarians with stage III colon cancer in the National Cancer Database received it. The remaining majority, who were all fit and survived ≥6 weeks postsurgery, could have derived benefit from adjuvant chemotherapy. This represents a substantial opportunity for quality improvement in treating octogenarians with stage III colon cancer.

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