Abstract
The increased risk of colorectal cancer (CRC) in patients with inflammatory bowel disease (IBD) has been well documented in the literature. The present study aimed to assess the characteristics and outcomes of rectal cancer in patients with IBD. This study was a retrospective review of a prospectively maintained IRB-approved database at Cleveland Clinic Florida. Rectal cancer patients with or without IBD treated with curative surgery between 2016 and 2020 were compared for demographics, disease characteristics, and pathologic and oncologic outcomes. The primary outcomes were 3-year overall survival (OS) and disease-free survival (DFS). Secondary outcomes were clinicopathologic outcomes including disease stage, tumor histology and histologic features, and treatments received. 238 patients with rectal cancer were included, 15 (6.3%) of whom had IBD. IBD patients were significantly younger (52.9 vs 60.3 years, p = 0.033), presented more often with cT1-2 tumors (64.3% vs 30.4%, p = 0.008), and signet-ring cell pathology (14.3% vs 2%, p = 0.02). IBD patients received neoadjuvant chemoradiation less often (40% vs 72.6%, p = 0.029) and had shorter time between diagnosis and surgery (7.5 vs 25 weeks, p = 0.013) than did non-IBD patients. Both groups had similar OS (36 vs 34.7 months, p = 0.431) and DFS (36 vs 32.9 months, p = 0.121). IBD patients with rectal cancer tend to present at a younger age, with a less invasive disease, and signet-ring carcinomas, and receive neoadjuvant treatment less often than non-IBD patients. Based on low level of evidence, IBD and non-IBD rectal cancer patients might have similar survival.

Abstract
BACKGROUND Gracilis muscle interposition (GMI) has been associated with favorable outcomes in treating complex perianal fistulas. Outcomes of GMI may vary according to the fistula etiology, particularly between rectovaginal fistulas in women and rectourethral fistulas (RUF) in men. The aim of this study was to assess the outcome of GMI to treat RUF acquired after prostate cancer treatment. METHODS This retrospective cohort study included male patients treated with GMI for RUF acquired after prostate cancer treatment between January 2000 and December 2018 in the Department of Colorectal Surgery, Cleveland Clinic Florida. The primary outcome was the success of GMI, defined as complete healing of RUF without recurrence. Secondary outcomes were length of hospital stay and postoperative complications. RESULTS This study included 53 male patients with a median age of 68 (range, 46-85) years. Patients developed RUF after treatment of prostate cancer with radiation (52.8%), surgery (34%), or transurethral resection of the prostate (TURP) (13.2%). Median hospital stay was 5 (IQR, 4-7) days. Twenty (37.7%) patients experienced 25 complications, the most common being wound infection and dehiscence. Primary healing after GMI was achieved in 28 (52.8%) patients. Fifteen additional patients experienced successful healing of RUF after additional procedures, for a total success rate of 81.1%. Median time to complete healing was 8 (range, 4-56) weeks. The only significant factor associated with outcome of GMI was wound dehiscence (p = 0.008). CONCLUSIONS Although the initial success rate of GMI was approximately 53%, it increased to 81% after additional procedures. Complications after GMI were mostly minor, with wound complications being the most common. Perianal wound dehiscence was significantly associated with failure of healing of RUF after GMI.

Abstract
BACKGROUND T4 rectal cancer is a challenging condition owing to the highly invasive nature of the tumour that may compromise R0 resection. The present study aimed to assess the outcomes of laparoscopic versus robotic-assisted resection of non-metastatic T4 rectal adenocarcinoma. METHODS This was a retrospective propensity score-matched analysis using the National Cancer Database between 2010 and 2019. Patients with pathological T4 non-metastatic rectal adenocarcinoma who underwent laparoscopic or robotic-assisted resection were compared and a propensity score-matched analysis was performed in a 1:1 manner. The main outcome measures were conversion to open surgery, mortality, readmission, resection margins, and overall survival. RESULTS After propensity score matching, 235 patients were included in each group. There were 260 (55.3 per cent) men and 210 (44.7 per cent) women, with a mean (s.d.) age of 61 (13.2) years. Patients in the robotic group had a statistically significantly lower conversion rate (8.9 per cent versus 17.9 per cent; P = 0.006), shorter median duration of hospital stay (5 versus 6 days; P = 0.007), higher overall survival rate (56.2 per cent versus 43.4 per cent; P = 0.007), and a longer median survival (60.8 versus 43.2; P = 0.025). There were no significant differences between the two groups with regard to positive resection margins, examined lymph nodes, 30-day and 90-day mortality rates, and 30-day readmission rate. CONCLUSIONS Robotic resections of T4 rectal cancer were associated with a significantly lower conversion rate and shorter duration of hospital stay than laparoscopic resections. The two approaches were comparable with regard to positive resection margins, short-term mortality, and readmission.

Abstract
BACKGROUND Circumferential resection margin is an important prognosticator for total mesorectal excision outcome. We investigated the status of mesorectal fascia on magnetic resonance imaging compared with circumferential resection margin on pathology and factors associated with status change. METHODS This was a retrospective analysis of a prospective database of rectal cancer patients who underwent surgery. Mesorectal fascia status on magnetic resonance imaging done before neoadjuvant therapy and circumferential resection margin status on pathology were compared. The study outcomes were factors associated with a margin status conversion between magnetic resonance imaging and pathology, and predictors of involved circumferential resection margin. RESULTS In total, 244 patients (average follow-up of 25.4 months) were included. Eighty-one (33.2%) patients had potentially involved mesorectal fascia in magnetic resonance imaging and 12 (4.9%) had involved circumferential resection margin in pathology. A total of 2.8% of patients had a conversion of clear mesorectal fascia in magnetic resonance imaging to involved circumferential resection margin. Abdominoperineal resection was significantly associated with this status change (odds ratio: 25, 95% confidence interval: 2.4-255.8, P = .007). In total, 7.4% of patients with potentially involved mesorectal fascia had persistently involved circumferential resection margin. Lack of total neoadjuvant therapy was associated with higher, yet statistically insignificant, odds of persistently involved circumferential resection margin (odds ratio: 12, 95% confidence interval: 0.65-220.8, P = .09). The significant independent predictors of involved circumferential resection margin were body mass index (odds ratio: 1.2, P = .016) and abdominoperineal resection (odds ratio: 4.22, P = .04). CONCLUSION Change of clear mesorectal fascia in magnetic resonance imaging to an involved circumferential resection margin in pathology was recorded in 2.8% of patients; abdominoperineal resection might be associated with this change. Approximately 7% of patients had persistent involvement of circumferential resection margin as determined by pathology. Omission of total neoadjuvant therapy might be associated with persistent margin involvement.

Abstract
BACKGROUND The proposed difficulty scoring system (DSS) may aid in preoperative planning for laparoscopic total mesorectal excision (L-TME) for rectal cancer. METHODS Fifty-three patients [28 males; 59.0 (31.0-88.0) years of age] treated for rectal cancer at our institution from 2/2011-5/2018 were identified. "Difficult operation" (DO) was defined as the presence of ≥3 factors: operative time ≥320 min, estimated blood loss >250 ml, intraoperative complications, conversion to laparotomy, >2 stapler applications, incomplete TME quality, and/or subjective perceived difficulty. Univariate analysis and multivariate logistic regression model with backward elimination method were used to obtain a DSS which consists of two factors: sex (male = 1 and female = 0) and body mass index (BMI) (≥30 kg/m2 = 1, <30 kg/m2 = 0). RESULTS In univariate analysis, sex (p = 0.0217), BMI (p = 0.0026), American Society of Anesthesiologists (ASA) score (p = 0.0372), and magnetic resonance imaging transverse diameter (p = 0.0441) correlated to DO. Multivariate analysis revealed that sex and BMI were the most important risk factors for a DO [area under the receiver operating characteristic curve [AUC] = 0.7761, 95% CI = (0.6443-0.9080)]. Male patients with a BMI ≥ 30 kg/m2 were more likely to experience a DO (77.8%). The simplified DSS did not weaken the discriminating power compared to multivariate logistic regression model (AUC 0.7696 vs. 0.7761, p = 0.7387). L-TME with a DSS of 0, 1, and 2 had a DO rate of 10%, 33.3%, and 77.8%, respectively. CONCLUSIONS A simplified DSS may be used preoperatively in preparation for L-TME.

Abstract
Neutropenic colitis is a severe condition usually affecting immunocompromised patients. Its exact pathogenesis is not completely understood. The main elements in disease onset appear to be intestinal mucosal injury together with neutropenia and the weakened immune system of the afflicted patients. These initial conditions lead to intestinal edema, engorged vessels, and a disrupted mucosal surface, which becomes more vulnerable to bacterial intramural invasion. Chemotherapeutic agents can cause direct mucosal injury (mucositis) or can predispose to distension and necrosis, thereby altering intestinal motility. This article aims to review current concepts regarding neutropenic colitis’ pathogenesis, diagnosis, and management.

Abstract
Objective: This study aimed to investigate the long-term outcomes of patients who undergo redo sphincteroplasty (RS). Methods: Patients with fecal incontinence (FI) who underwent RS between November 1988 and December 2011 were retrospectively identified from a prospective database. A questionnaire and telephone survey assessed current Cleveland Clinic Fecal Incontinence Score (CCFFIS; best 0, worst 20) and Fecal Incontinence Quality of Life (FIQoL; best 4.1, worst 1) scale. Success was defined as no further continence surgery, no stoma and CCFFIS <9 at completion of follow-up. The Wilcoxon and Mann-Whitney U tests were used for comparing quantitative variables. Bivariate logistic regression analysis was done to identify predictive factors for success. Results: Fifty-six (66.7%) of 84 patients who underwent RS were available for evaluation at a median follow-up of 74 (range: 12–283) months. The mean CCFFIS decreased from 16.5 ± 3.7 to 11.9 ± 6.6 (P < 0.001) at last follow-up. Twelve patients (21.4%) underwent further continence surgery for failed sphincteroplasty, three (5.4%) of whom had a permanent stoma. Eighteen patients (32.1%) had a CCFFIS <9 at the completion of follow-up, and 16 (28.6%) had long-term success. Twenty-four patients evaluated for FIQoL had a mean value of 2.6 (range: 1.0–4.1). Postoperative CCFFIS was correlated with FIQoL (Spearman’s correlation coefficient = −0.854, P < 0.001). Logistic regression analysis did not reveal any significant predictive variables for success of RS. Conclusion: Based on our criteria for success, the long-term success rate for RS over a median of 74 months is poor.

Abstract
The consequences of slaughter on the formation of lipid metabolites and oxidative stability of fish muscle during long term frozen storage (-10 °C) were evaluated using farmed rainbow trout killed by asphyxia in air or percussion. The level of major adenine nucleotides and their related compounds was determined in order to check the stress level during slaughter. Plasma lipid metabolites were studied through the determination of eicosanoids and docosanoids such as prostaglandins, leukotrienes, thromboxanes, isoprostanes, resolvins, hydroxides, hydroperoxides, coming from eicosapentaenoic (EPA), arachidonic (ARA), and docosahexaenoic (DHA) acids. In addition, lipid oxidative stability of fillets was monitored. Results revealed that stress during slaughter can greatly influence oxidative stress and oxidative stability of rainbow trout fillets. In fact, asphyxia, which was the most stressful, induced a higher production of some lipid mediators such as hydroperoxides and EPA-derived prostaglandins, such as 12-HpHEPE/15-HpHEPE and PGD3/PGE3. As a consequence, fillets derived from asphyxiated fish were less stable in terms of oxidative stability and showed lower shelf-life.

Abstract
OBJECTIVES Immunoperoxidase staining of prostate tissues with antibodies to high molecular weight cytokeratin, which selectively labels basal cells, has recently been shown to be useful in the diagnosis of prostate cancer in academic centers. A growing sector in pathology is large independent laboratories, where little is known regarding practice patterns. The following study evaluated the use of high molecular weight cytokeratin in an independent laboratory specializing in prostate needle biopsies. METHODS In a 2-month period (July 1, 1994 to August 31, 1994), 4047 prostate needle biopsies were evaluated. RESULTS Without the use of ancillary studies, 2710 (67%) were diagnosed as benign, 978 (24.1%) were diagnosed as cancer, and 23 (0.6%) were diagnosed as high-grade prostate intraepithelial neoplasia. The remaining 336 atypical cases (8.3%) were further evaluated with antibodies to higher molecular weight keratin. Of the 336 cases, 253 (6.2% of total) were resolved as diagnostic for cancer, 68 (1.7% of total) were diagnosed as benign, and 15 (0.4% of total) remained atypical. The cost of performing high molecular weight cytokeratin was approximately $5.00 per case, which was not passed on to the patient. CONCLUSIONS The use of high molecular weight cytokeratin decreased the rate of an atypical prostate biopsy from 8.3% to 0.4% at a negligible cost to the pathologist and patient.
