    ABSTRACT: Background: Current guidelines recommend extended-duration thromboprophylaxis for all abdominal oncologic resections. However, other high-risk patients may benefit from extended thromboprophylaxis. Objective: The purpose of this study was to identify risk factors for postdischarge venothromboembolism after colorectal procedures. Design: This was a retrospective cohort study. Data sources: The New York Statewide Planning and Research Cooperative System database (2005-2013) was the data source for this study. Study selection: Colon and rectal resections were evaluated. Cases with in-hospital mortality or length of stay ≥30 days were excluded. Main outcome measures: Postdischarge venothromboembolism was defined at 30-days after the procedure requiring representation to the emergency department or hospital admission with a new diagnosis of venothromboembolism using International Classification of Diseases, Ninth Revision, codes. Factors associated with postdischarge venothromboembolism were then evaluated using a hierarchical bivariate analysis. A hierarchical mixed-effects model was created using a manual stepwise approach assessing variables meeting p < 0.1 on bivariate analysis. Results: Among 128,163 patients, postdischarge venothromboembolism occurred in 0.7% (n = 789) of the population. Multiple factors were associated with postdischarge venothromboembolism on bivariate analysis. On multivariable analysis, benign conditions requiring operative intervention remained at high risk, with ulcerative colitis imparting an 93% increased odds when compared with other resections (OR, 1.93 (95% CI: 1.30-2.86); p = 0.001). Advanced malignancies (stages III and IV) were associated with increased postdischarge venothromboembolism risk, whereas stage I and II malignancies were not. The only protective factor was a laparoscopic procedure (OR, 0.80 (95% CI: 0.67-0.95); p = 0.010). There was no significant difference in procedure type after controlling for primary diagnosis. Limitations: This was a retrospective analysis of administrative data with inherent limitations. Only patients who presented with postdischarge venothromboembolism to a hospital within New York State were captured. Conclusions: This study identifies risk factors for postdischarge venothromboembolism and suggests that ulcerative colitis increases risk for postdischarge venothromboembolism whereas Crohn's disease does not. Ulcerative colitis postdischarge venothromboembolism rates exceeded even those of malignancy, suggesting that a future study is necessary to determine the efficacy of extended duration thromboprophylaxis in high-risk benign conditions, such as ulcerative colitis.

    ABSTRACT: BACKGROUND: The potential advantages of robot-assisted laparoscopy are being increasingly investigated, although data on its efficacy in benign colorectal surgery are scarce. OBJECTIVE: We compared the early postoperative outcome in robot-assisted IPAA with open surgery procedures. DESIGN: This was an observational study based on prospectively collected data obtained from chart reviews. SETTING: The single-center data set covers patients operated on from January 13, 2004, to September 16, 2014, at a specialist center. PATIENTS: Patients with ulcerative colitis undergoing IPAA surgery were included. MAIN OUTCOME MEASURES: Study end points included the duration of operation, admission length, complications (Clavien-Dindo), reoperations, and readmissions. RESULTS: Eighty-one robot-assisted and 170 open IPAA procedures were performed. The duration of operation was significantly longer for robot-assisted laparoscopic procedures (mean difference, 154 minutes; CI, 140–170). During a mean follow-up of 102 days, no significant differences in the distribution of complications were found (Spearman p = 0.12; p = 0.07), and no postoperative deaths occurred in either group. Postoperative admission length was shorter following robot-assisted procedures (mean difference, –1.9; CI, –3.5 to –0.3), whereas 40% of patients were readmitted, compared with 26% of patients who had open surgery (OR, 1.9; CI, 1.1–3.4). Pouch failure occurred in 3 patients (1 following robot-assisted laparoscopy; 2 following open surgery). On multivariate regression analyses, robot-assisted laparoscopy was associated with a significantly longer duration of operation (mean difference, 159 minutes; CI, 144–174), and more readmissions for any cause (OR, 2; CI, 1.1–3.7). LIMITATIONS: This was a nonrandomized, single-center observational study. CONCLUSION: In this implementation phase, robot-assisted IPAA surgery offers acceptable short-term outcomes. The limitations of this observational study call for randomized controlled trials with long-term follow-up and exploration of functional results.

    ABSTRACT: Background: The best management for diverticulitis with abscess formation remains unknown. Objective: The purpose of this study was to determine the natural course and outcomes of patients with medically treated diverticular abscess. Design: We conducted a retrospective review of all patients at our institution with diverticular abscess confirmed by CT from 2004 to 2014. Settings: This study was conducted in a tertiary referral hospital. Patients: A total of 1194 patients were treated for acute diverticulitis in 10 years; 210 patients with CT-documented diverticular abscess were analyzed (140 men (66.7%) and 70 women (33.3%); median age 45 years; range, 23-84 years). Main outcome measures: Overall recurrence and disease complication rates, as well as the need for subsequent operation after initial successful nonsurgical management, were measured, along with analysis of the whole cohort and the subgroup of patients with percutaneous drainage for diverticular abscess. Results: During the initial presentation, 25 patients failed nonoperative management and required an urgent operation. A total of 185 patients were initially successfully managed without surgery and were discharged from the hospital. Of these, recurrent diverticulitis developed in 112 (60.5%) after an average time interval of 5.3 months (range, 0.8-20.0 months); 47 patients (42%) experienced more than 1 episode. The modified Hinchey stage at time of recurrence (compared with index stay) increased in 51 patients (45.6%). Seventy one (63%) of 112 recurrences showed local disease complications (recurrent abscess, fistula, stricture, or peritonitis). Fistula formation (colovesicular/colovaginal/colocutaneous) and recurrent abscess were the 2 most frequent complications. Twenty nine (26%) of 112 recurrences required an urgent operation; overall, 66 (59%) of 112 patients eventually underwent surgery at our institution. The original abscess size in patients who later developed recurrences was significantly larger than in patients who did not develop recurrence (5.3 vs 3.2 cm; p < 0.001). Paradoxically, larger abscesses also had a higher chance of successful CT-guided drainage (average size, 6.5 cm; range, 1.1-14 cm), yet CT-guided drainage did not change the overall outcome. Of 65 (31.0%) of 210 patients with CT-guided drainage, 45 (73.8%) of 61 after initial success experienced a recurrence. Furthermore, local disease complications at the time of recurrence were noted in 32 of 61 patients (52.5% of all CT-guided drainage, 71.1% of post-CT-guided drainage recurrences), and 13 (29.2%) of 45 patients with recurrence after successful CT-guided drainage subsequently required an urgent operation. Limitations: The study was limited by its retrospective noncomparative design. Conclusions: Diverticular abscesses represent complicated diverticulitis and are associated with a high risk of recurrences and disease complications. Recurrences (contrary to other series) were often more severe than the index presentation. The successful CT-guided drainage of a diverticular abscess does not appear to lower the risks of future recurrence or complication rates and frequently is only a bridge to surgery. After initial successful nonoperative management, patients with diverticular abscess should be offered interval elective colectomy (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A216).

    ABSTRACT: Background: Although right-sided diverticulitis is perceived to have a higher incidence among Asians and infrequently requires surgical management in comparison with sigmoid diverticulitis, it is unknown whether differences in outcomes are due to ethnic disparity or disease pathophysiology. Objective: The aim of this study was to determine the surgical outcomes for Asian and non-Asian patients with diverticulitis who underwent colectomy. Design: Patients identifiable by ethnicity in the Nationwide Inpatient Sample with diverticulitis and colectomy between 2004 and 2010 were included. Univariate comparisons were made between Asian and non-Asian patients by using t tests for continuous variables and χ tests for categorical variables. Propensity score matching analysis was performed to compare Asian patients with otherwise similar non-Asian patients. Patients: Included were 58,142 non-Asian and 335 Asian patients with diverticulitis who underwent a colectomy. Main outcome measures: The primary outcomes were in-hospital mortality, hospital length of stay, and total costs. Results: Asian patients were younger (56.1 vs 59.2 years, p < 0.0001), were more likely to undergo a right colectomy (22.7% vs 4.1%, p < 0.0001), and were more likely to have emergent/urgent surgery than the non-Asian patients (67.1% vs 49.8%, p < 0.0001). Without controlling for patient/disease factors, there were statistically significant differences in mortality (non-Asian 2.2% vs Asian 4.2%; p = 0.014), length of stay (non-Asian 8.9 vs Asian 9.8 days; p = 0.0166), and costs (non-Asian $18,783 vs Asian $21,901; p = 0.001). Propensity score matching comparing 333 non-Asian patients with 333 similar Asian patients showed that, whereas differences in cost and length of stay became insignificant, the difference in mortality remained statistically significant. Limitations: The ethnicity variable was not uniformly collected by all states within the Nationwide Inpatient Sample database. Conclusions: Among patients undergoing a colectomy for diverticulitis, a higher mortality was observed in Asian patients and right-sided disease. Future longitudinal studies comparing the natural history and outcomes of management between right- and left-sided diverticulitis are necessary to investigate whether a true ethnic disparity exists.

    ABSTRACT: Background: Anastomotic leaks after restorative resections for rectal cancer may lead to worse long-term outcomes. Objective: The purpose of this study was to evaluate the best current evidence assessing anastomotic leaks in rectal cancer resections with curative intent and their impact on survival and cancer recurrence. Data sources: A meta-analysis was performed using MEDLINE, EMBASE, and Cochrane search engines for relevant studies published between January 1982 and January 2015. Study selection: Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology was used to screen and select relevant studies for the review using key words "colorectal surgery; colorectal neoplasm; rectal neoplasm" and "anastomotic leak." Intervention: Anastomotic leak groups were compared with nonanastomotic leak groups. Main outcome measures: ORs were calculated from binary data for local recurrence, distant recurrence, and cancer-specific mortality. A random-effects model was then used to calculate pooled ORs with 95% CIs. Results: Eleven studies with 13,655 patients met the inclusion criteria. This included 5 prospective cohort and 6 retrospective cohort studies. Median follow-up was 60 months. Higher cancer-specific mortality was noted in the leak group with an OR of 1.30 (95% CI, 1.04-1.62; p < 0.05). Local recurrences were more likely in rectal cancer resections complicated by anastomotic leaks (OR = 1.61 (95% CI, 1.25-2.09); p < 0.001). Distant recurrence was not more likely in the anastomotic leak group (OR = 1.07 (95% CI, 0.87-1.33); p = 0.52). Limitations: All 11 studies are level 3 evidence cohort studies. Additional sensitivity analyses were performed to minimize cross-study heterogeneity. Conclusions: Anastomotic leaks after restorative resections for rectal cancer adversely impact cancer-specific mortality and local recurrence.

    ABSTRACT: Background: Management of rectal cancer has become multidisciplinary and is driven by the stage of the disease, with increased focus on restaging rectal cancer after neoadjuvant therapy. Objective: The purpose of this study was to assess the relative impact of restaging after preoperative chemoradiation with FDG-PET scan, CT, and MRI in the management of patients with rectal cancer. Design: This was a retrospective study from a single institution. Settings: This study was conducted at a tertiary cancer center. Patients: A total of 199 patients met the inclusion criteria: patients with rectal adenocarcinoma; staged with positron emission tomography, CT, and MRI; T2 to T4, N0 to N2, M0 to M1; treated with neoadjuvant chemoradiation 50.4 Gy and infusional 5-fluorouracil; and restaged 4 weeks after chemoradiation before surgery between 2003 and 2013. Main outcome measures: Comparisons of the tumor stage among different imaging modalities before and after neoadjuvant chemoradiation were performed. The impact of restaging on the management plan was assessed. Results: The stage at presentation was T2, 8.04%; T3, 65.33%; T4, 26.63%; N0, 17.09%; N1, 47.74%; N2, 34.67%; M0, 81.91%; and M1, 18.09%. Changes in disease stage postneoadjuvant chemoradiation were observed in 99 patients (50%). The management plans of 29 patients (15%) were changed. The impact of each restaging modality on management for all of the patients was positron emission tomography, 11%; CT, 4%; and MRI, 4%. In patients with metastatic disease at primary staging, the relative impact of each restaging modality in changing management was positron emission tomography, 32%; CT, 18%; and MRI, 6%. Limitations: This study was limited by its single-center and retrospective design. Operations were performed 4 weeks after restaging. Conclusions: Changes in the extent of disease after long-course chemoradiotherapy result in changes of management in a significant percentage of patients. Positron emission tomography has the most significant impact in the change of management overall, and its use in restaging advanced rectal cancer should be further explored.

    ABSTRACT: Background: Larger tumor size and lymph node involvement are traditionally associated with increased colon cancer-specific mortality. Objective: We sought to determine whether patients with very small tumors associated with lymph node involvement are at paradoxically increased risk of colon cancer-specific mortality in comparison with those who have larger tumors and lymph node involvement. Design: This is a retrospective cohort study using the Surveillance, Epidemiology, and End Results database. Setting: Geographic areas included in one of the 18 Surveillance, Epidemiology, and End Results registries were used. Patients: We identified 99,594 patients with nonmetastatic colon adenocarcinoma treated with surgery between 1988 and 2001. Main outcome measures: The primary predictor variables were regional lymph node involvement and primary tumor size by longest dimension, grouped into the following predetermined strata: <5 mm, 5 to 19 mm, 20 to 39 mm, 40 to 59 mm, ≥ 60 mm. We used competing risks regression to determine differences in the risk of colon cancer-specific mortality between strata after controlling for T stage, tumor grade, age, year of diagnosis, race, and number of dissected lymph nodes. Results: Median follow-up among censored patients was 12.9 years. We found a significant interaction between lymph node involvement and tumor size (p < 0.05). Among those with node-negative disease, colon cancer-specific mortality increased monotonically with tumor size. In contrast, among those with node-positive disease, patients with the smallest tumors (<5 mm) were at increased risk of 10-year colon cancer-specific mortality compared with those with tumors sized 5 to 19 mm, 20 to 39 mm, 40 to 59 mm, and ≥60 mm (53.3% vs 30.1%, 37.5%, 39.2%, and 39.7%; adjusted hazard ratios, 1.63-2.24; p < 0.05 in all cases). Limitations: The main limitations are the retrospective design and information available in the study database. Conclusion: In the setting of lymph node involvement, very small tumor size may predict for increased colon cancer-specific mortality compared with larger tumors. Smaller tumors associated with lymph node involvement may represent more aggressive malignancies with a distinct biology that merits further investigation.

    ABSTRACT: Background: Regarding anoplasty for anal stenosis, it is not clear to what extent the final anal caliber should be targeted. Objective: The aim of this study was to investigate the results of diamond-flap anoplasty performed in a calibrated manner for the treatment of severe anal stenosis due to a previous hemorrhoidectomy. Design and setting: Prospectively prepared standard forms were evaluated retrospectively. Patients and interventions: Anoplasty with unilateral or bilateral diamond flaps was performed for moderate or severe anal stenosis, targeting a final anal caliber of 25 to 26 mm. The demographic characteristics, causes of anal stenosis, number of previous surgeries, anal stenosis staging (Milsom and Mazier), anal calibers (millimeter), the Cleveland Clinic Incontinence Score, and the modified obstructed defecation syndrome Longo score were recorded on pre-prepared standard forms, as well as postoperative complications and the time of return to work. Results: From January 2011 to July 2013, 18 patients (12 males, 67%) with a median age of 39 years (range, 27-70) were treated. All of the patients had a history of previous hemorrhoidectomy. The number of previous corrective interventions was 2.1 ± 1.8 (range, 0-4), and 2 patients had a history of failed anoplasty. Five patients (28%) had moderate anal stenosis and 13 (72%) had severe anal stenosis. Preoperative, intraoperative, and 12-month postoperative anal calibration values were 9 ± 3 mm (range, 5-15), 25 ± 0.75 mm (range, 24-26), and 25 ± 1 mm (range, 23-27) (p < 0.0001, for immediate postoperative and 12-month postoperative anal calibers compared with the intraoperative). Preoperative and 12-month postoperative Cleveland Clinic Incontinence Scores were 0.83 ± 1.15 (range, 0-4) and 0.39 ± 0.70 (range, 0-2) (p = 1.0). The clinical success rate was 88.9%. No severe postoperative complications were observed. Limitations: This study was limited because it was a single-armed, retrospective analysis of prospectively designed data. Conclusion: Diamond-flap anoplasty performed in a standardized and calibrated manner is a highly successful method for the treatment of anal stenosis caused by previous hemorrhoidectomy.

    ABSTRACT: Background: The benefits of adjuvant chemotherapy in the treatment of colorectal cancer are well established. Chemotherapy-induced diarrhea is a common adverse effect of these regimens. The occurrence of chemotherapy-induced diarrhea not only directly affects patient health but may also compromise treatment efficacy because of consequent dosing alterations or discontinuation. Objective: This study aimed to investigate the effect of diverting loop ileostomy during chemotherapy on the occurrence and consequences of chemotherapy-induced diarrhea. Design: This was a retrospective evaluation of a prospective surgical database. Settings: This was a single-institution retrospective study. Patients: All patients receiving curative adjuvant chemotherapy after anterior resection for colorectal cancer at Auckland Hospital from 2002 to 2013 were retrospectively evaluated. Main outcome measures: Patient-, perioperative-, and chemotherapy-related variables were collected. Chemotherapy-induced diarrhea occurrence was graded according to National Cancer Institute Common Terminology Criteria for Adverse Events. Logistic regression analysis was performed to identify independent predictors for chemotherapy-induced diarrhea occurrence, treatment modifications, and hospital admission. Results: A total of 109 identified patients received 691 chemotherapy cycles; 84% of patients with a diverting ileostomy experienced chemotherapy-induced diarrhea compared with 47% in those who were not defunctioned (p < 0.01). On logistic regression analysis, the presence of a diverting ileostomy during chemotherapy was an independent predictor of chemotherapy-induced diarrhea grade 3 or higher (OR, 13.6 (95% CI: 1.2-150.9); p = 0.02), the need for a dosing reduction (OR, 4.0 (95% CI: 1.3-12.4); p = 0.02), and the need for any modification in the chemotherapy regimen (OR, 3.4 (95% CI: 1.2-9.6); p = 0.02). Limitations: This study is limited by its retrospective design, potentially limiting the accuracy of chemotherapy-induced diarrhea grade reporting. Conclusions: The presence of an ileostomy during adjuvant chemotherapy is a predictor of severe chemotherapy-induced diarrhea and the need for modifications in the chemotherapy regimen. This may have important consequences for long-term survival. Prospective investigation is needed to further assess the impact of diverting ileostomy on the delivery of chemotherapy and oncologic outcomes.

    ABSTRACT: BACKGROUND: Total mesorectal excision has long been the standard of care for patients with rectal cancer. However, in select patients, local excision is an appropriate alternative option. The role of adjuvant radiation therapy in patients treated with local excision is controversial and evidence is lacking. OBJECTIVE: The purpose of this study was to report oncological outcomes of patients with rectal cancer treated with local excision and adjuvant radiation. DESIGN: This study was a retrospective chart review. SETTINGS: The study was conducted at the BC Cancer Agency, a tertiary referral hospital. PATIENTS: A total of 93 patients with node-negative rectal cancer treated with local excision and adjuvant radiotherapy between 2001 and 2010 were included in the study. MAIN OUTCOME MEASURES: Patient and tumor characteristics are reported. Five-year local control, progression-free survival, and overall survival were analyzed using Kaplan-Meier methods. RESULTS: Five-year overall survival, local control, and progression-free survival for patients treated with local excision and adjuvant radiotherapy were 78.5%, 86.1%, and 83.8%. In T1 disease, local control was 92.5%. LIMITATIONS: Referral bias, selection bias, lack of uniform surveillance, and retrospective analysis are the study limitations. CONCLUSIONS: Local excision with adjuvant radiotherapy provides a good level of local control in T1 disease and remains a good treatment option for patients who are either medically not suitable for a more radical surgical approach or who refuse this procedure. Local excision and radiotherapy should not be advocated in T2/T3 disease; however, it can provide a good alternative in those patients who are not fit enough for a more radical operation.

    ABSTRACT: BACKGROUND: Prolonged intestinal paralysis can be a problem after gastrointestinal surgery. Several systematic reviews and meta-analyses have suggested the efficacy of gum chewing for the prevention of postoperative ileus. OBJECTIVE: The purpose of this study was to examine the efficacy of gum chewing for the recovery of bowel function after surgery for left-sided colorectal cancer and to determine the physiological mechanism underlying the effect of gum chewing on bowel function. DESIGN: This was a single-center, placebo-controlled, parallel-group, prospective randomized trial. SETTINGS: The study was conducted at a general hospital in Japan. PATIENTS: Forty-eight patients with left-sided colorectal cancer were included. INTERVENTIONS: The patients were randomly assigned to a gum group (N = 25) and a control group (N = 23). Four patients in the gum group and 1 in the control group were subsequently excluded because of difficulties in continuing the trial, resulting in the analysis of 21 and 22 patients in the respective groups. Patients in the gum group chewed commercial gum 3 times a day for ≥5 minutes each time from postoperative day 1 to the first day of food intake. MAIN OUTCOME MEASURES: The time to first flatus and first bowel movement after the operation were recorded, and the colonic transit time was measured. Gut hormones (gastrin, des-acyl ghrelin, motilin, and serotonin) were measured preoperatively, perioperatively, and on postoperative days 1, 3, 5, 7, and 10. RESULTS: Gum chewing did not significantly shorten the time to the first flatus (53 ± 2 vs 49 ± 26 hours; p = 0.481; gum vs control group), time to first bowel movement (94 ± 44 vs 109 ± 34 hours; p = 0.234), or the colonic transit time (88 ± 28 vs 88 ± 21 hours; p = 0.968). However, gum chewing significantly increased the serum levels of des-acyl ghrelin and gastrin. LIMITATIONS: The main limitation was a greater rate of complications than anticipated, which limited the significance of the findings. CONCLUSIONS: Gum chewing changed the serum levels of des-acyl ghrelin and gastrin, but we were unable to demonstrate an effect on the recovery of bowel function.

    ABSTRACT: BACKGROUND: Malignant infiltration of the pubic bone traditionally is considered inoperable. Consequently, there is little published on surgical approaches to resection of the anterior pelvic bone. En bloc partial or complete pubic bone excision can be performed depending on the degree of involvement. OBJECTIVE: This article describes our surgical approach of pelvic exenteration with en bloc composite pubic bone excision. DESIGN: The surgical technique describes 2 distinct aspects of the surgery, first, a perineal as opposed to abdominal transection of the urethra, and, second, varying extents of en bloc pubic bone excision. SETTINGS: This study was conducted at a tertiary care hospital. MAIN OUTCOME MEASURES: Pelvic tumors infiltrating the pubic bone require radical en bloc composite bone resection to achieve an R0 margin that should translate to longer-term survival versus nonoperative treatments. RESULTS: Results of our study are currently under review. CONCLUSIONS: As the magnitude of pelvic exenteration surgery continues to evolve for all compartments of the pelvis, malignant infiltration of the anterior pelvic bone should not be considered a contraindication to surgery.
