RESUMO
BACKGROUND AND OBJECTIVES: This study compares surgical and oncological outcomes in patients with Crohn's disease (CD)-related colorectal cancer (CRC) to those with sporadic CRC. METHODS: Patients treated between 1983 and 2013 were matched by stage, age, gender, American Society of Anesthesiologists (ASA), cancer site, and adjuvant chemotherapy. RESULTS: For stages I and II, 107 patients were matched (58.9% male, mean age 59 years, 59.8% with ASA score 3). Tumor sites included the right (17.7%), transverse (4.7%), left colon (15.9%), and rectum (61.7%). CD patients exhibited longer operative times, higher pT stages, and 2.60 times the odds of postoperative complications (p = 0.03). Overall and disease-free survival were similar. For stage III, 54 patients were matched (57.4% male, mean age 54 years, 46.3% with ASA score 3). The cancer site distribution was right (29.7%), transverse (3.7%), left colon (18.5%), and rectum (48.1%). CD patients had longer operative times, increased blood loss, more involved lymph nodes, higher pT- and pN-stages. The rates of postoperative complications were not different (p = 0.19). CD-related CRC patients had similar overall (p = 0.06), and local recurrence-free survival (p = 0.07). CONCLUSIONS: Despite facing worse perioperative and pathological characteristics, survival differences in stages I-III CD-related CRC compared with sporadic CRC patients were not significantly different.
RESUMO
BACKGROUND: Tissue harvesting at the time of surgery offers surgeons and scientists a unique opportunity to discover and better understand disease pathophysiology. Tissue biobanking presents challenges in patient consents, specimen collection, preparation, and storage, but the potential for scientific discovery justifies the effort. Although the number of tissue biobanks is increasing worldwide, information regarding necessary infrastructure, process flow, and management of expected obstacles is lacking. OBJECTIVE: To provide a framework and motivation for clinician scientists intending to start an intestinal tissue biobank under their direction. DATA SOURCES: The Carlino Family Inflammatory Bowel and Colorectal Diseases Biobank is housed at the Milton S. Hershey Medical Center. STUDY SELECTION: Review. INTERVENTION: Implementation of a surgical tissue biobank at a large tertiary care institution. MAIN OUTCOME MEASURES: Assess critical challenges and obstacles over the years as well as keys to the success of the program. RESULTS: Over 2 decades, the institutional biobank grew from an IBD biobank to one which now incorporates thousands of surgical specimens representing numerous colorectal diseases. This was done through a process of refinement focusing on patient recruitment and an efficient consenting and specimen management process. The biobank's success is further insured by institutional, external, and philanthropic support; scientific collaborations; and sharing of biological specimens with other groups of dedicated researchers. LIMITATIONS: This is a single-center experience in collecting surgically resected colorectal specimens. CONCLUSIONS: Surgical specimen biobanks are essential in studying disease cause using genomics, transcriptomics, and proteomic technologies. Therefore, surgeons, clinicians, and scientists should build biobanks at their institutions to promote further scientific discovery and improve specimen diversity.

INTRODUCTION: Colonic self-expanding metal stents (SEMS) can be used to relieve malignant and benign large bowel obstruction (LBO) as a bridge to surgery (BTS) and for palliation. Guidelines suggest the use of fluoroscopic guidance for deployment. This may be difficult to obtain after hours and in certain centers. We aimed to determine the outcomes of stenting under endoscopic guidance alone. METHODS: All patients who underwent SEMS insertion in our tertiary referral center between August 2010 and June 2021 were identified from a prospectively maintained database. Patient demographics (age/gender), disease characteristics (benign versus malignant/location/stage), stenting intent (BTS versus palliative), and outcomes (technical success/stoma/time from stenting to resection/death/study end) were analyzed. RESULTS: Fifty-three (n = 39, 73.6% male) patients underwent SEMS insertion. Indications included colorectal carcinoma (n = 48, 90.6%), diverticular stricture (n = 3), and gynecological malignancy (n = 2). In five (9.4%) patients (four BTS and one palliative), SEMSs deployment was not completed because of the inability to pass the guidewire. All underwent emergency surgery. In the BTS cohort (n = 29, median 70.4 [range 40.3-91.8] years), 10 patients underwent neoadjuvant chemoradiotherapy. The permanent stoma rate was 20.7% (n = 6). There was no 30- or 90-d mortality. In the palliative cohort (n = 24, median age 77.1 [range 54.4-91.9]), 16 (66.7%) were deceased at the study end. The median time from stenting to death was 5.2 (2.3-7.9) months. CONCLUSIONS: SEMS placed under endoscopic visualization alone, palliatively and as a BTS, had acceptable stoma, morbidity, and mortality rates. These results show that SEMS insertion can be safely performed without fluoroscopy.

PURPOSE: Previously considered a disease of old age, diverticular disease is increasingly prevalent in younger populations. Guidelines on surgical resection have shifted from recommending resection for all young onset patients to an individualized approach. Therefore, we aim to determine demographics and outcomes including radiographic and surgical recurrence rates in patients < 40 years old undergoing resection for diverticular disease. METHODS: A retrospective, single center study was performed. All patients ≤ 39 years undergoing operative intervention for left-sided diverticular disease between Jan 2010 and July 2017 were included. Recurrence was determined by individual review of imaging and operative reports. RESULTS: Overall, 147 (n = 107/72.8% male, mean age = 34.93 ± 4.12 years) patients were included. The majority were ASA 1 or 2 (n = 41/27.9% and n = 82/55.8%). The most common surgical indication was uncomplicated diverticulitis (n = 77, 52.4%) followed by perforation (n = 26/17.7%). The majority (n = 108/73.5%) of cases were elective. Seventy-nine (57.3%) of all cases were performed laparoscopically. Primary anastomosis without diversion was the most common surgical outcome (n = 108/73.5%). Median length of stay was 5 (4, 7) days. There was no mortality. There were three (2.0%) intraoperative and 38 (25.9%) postoperative complications. The most common complication was anastomotic leak (n = 6/4.1%). The majority (n = 5) of leaks occurred after elective surgery. Two neoplastic lesions (1.3% of cohort) were found (1 adenoma with low-grade dysplasia/1 polyp cancer). Over a mean follow-up of 96 (74, 123) months, only 2 (1.3%) patients experienced a surgical or radiological recurrence. CONCLUSION: Both neoplasia and recurrence after resection for diverticular disease in young onset patients are rare. Leaks after primary anastomosis even in the elective setting warrant careful consideration of a defunctioning ileostomy.

AIM: Diverting loop ileostomy reversal (DLI-R) is routinely performed from 2-6 months following ileal pouch-anal anastomosis (IPAA). The safety of delayed reversal after IPAA is not well-defined. The aim of this study was to determine if prolonged diversion is associated with adverse outcomes compared to routine closure. METHODS: Adult patients undergoing primary IPAA with DLI from 2000 to 2021 were included in this retrospective cohort study from our institutional database. Patients were stratified into tertiles based on timing of reversal: Routine (56-116 days), Delayed (117-180 days), or Prolonged (>6 months). Univariate analysis compared categorical variables between groups. Patients reversed at <8 weeks were excluded. RESULTS: In total, 2615 patients underwent DLI-R following IPAA (3-stage 61%, 2-stage 39%; mean age 39.9 years). DLI-R was performed as Routine, Delayed and Prolonged in 1908 (72.9%), 426 (16.4%) and 281 (10.8%), respectively. Overall, DLI-R related complications occurred in 12.4% (n = 324). The complication rate in the Routine group was 11% (n = 210), in the Delayed group was 12.2% (n = 52) and in the Prolonged group was 22.1% (n = 62). Reasons for prolonged diversion in the Prolonged group were complications at the time of IPAA in 207 (73.9%) or patient preference/scheduling in 73 (26.1%). DLI-R >6 months after IPAA due to complications had higher rates of overall complications following ileostomy reversal (OR 2.6, 95% CI 1.85-3.72, p < 0.001) whereas when DLI-R was delayed due to preference/scheduling outcomes were not different than the Routine group (p = 0.28). CONCLUSION: Prolonged time to ileostomy reversal after IPAA is probably safe without increased risk of complications when due to patient preference.

BACKGROUND: The laparoscopic approach for colon cancer has become widely accepted. However, its safety for T4 tumors, and particularly for T4b tumors when local invasion to adjacent structures occurs, remains controversial. This study aimed to compare short and long-term outcomes in patients undergoing laparoscopic vs. open resection for T4a and T4b colon cancers. METHODS: A prospectively maintained, single-institution database was queried to identify patients with pathological stage T4a and T4b colon adenocarcinomas electively operated on between 2000 and 2012. Patients were divided into two groups based on the use of laparoscopy. Patient characteristics, perioperative, and oncologic outcomes were compared. RESULTS: One hundred and nineteen patients [41 laparoscopic (L), 78 open surgeries (O)] met the inclusion criteria. No difference was observed in age, gender, BMI, ASA, and procedure between groups. Tumors treated by L were smaller than O (p = 0.003). No difference was observed in morbidity, mortality, reoperation, or readmission between the groups. Length of hospital stay was shorter in L than O (6 vs. 9 days, p = 0.005). Conversion to open was necessary in 22% of all T4 tumors laparoscopic cases. However, when tumors were subdivided by pT4 classification, conversion was necessary for 4 of 34 (12%) pT4a patients vs. 5 of 7 (71%) pT4b patients (p = 0.003). In the pT4b cohort (n = 37), more tumors were treated by the open approach (30 vs. 7). For pT4b tumors, the R0 resection rate was 94% (86% in L vs. 97% in O, p = 0.249). The use of laparoscopy did not impact overall survival, disease-free survival, cancer-specific survival, or tumor recurrence overall in all T4 or T4a and T4b tumors. CONCLUSIONS: Laparoscopic surgery can be safely performed in pT4 tumors with similar oncologic outcomes as compared to open surgery. However, for pT4b tumors, the conversion rate is very high. The open approach may be preferable.

PURPOSE: Endometriosis involving the colon and/or rectum (CRE) is operatively managed using various methods. We aimed to determine if a more limited excision is associated with 30-day complications, symptom improvement, and/or recurrence. METHODS: This is a retrospective review of consecutive cases of patients who underwent surgical management of CRE between 2010 and 2018. Primary outcomes were the associations between risk factors and symptom improvement, 30-day complications, and time to recurrence. Multivariable logistic regression assessed the independent risk factors. RESULTS: Of 2681 endometriosis cases, 142 [5.3% of total, mean age 35.4 (31.0; 39.0) years, 73.9% stage IV] underwent CRE excision (superficial partial = 66.9%, segmental = 27.5%, full thickness = 1.41%). Minor complications (14.8%) were associated with blood loss [150 (112; 288) vs. 100 (50.0; 200) mls, p = 0.046], Sigmoid involvement [45.5% vs. 12.2%, HR 5.89 (1.4; 22.5), p = 0.01], stoma formation [52.6% vs. 8.9%, HR 10.9 (3.65; 34.1), p < 0.001], and segmental resection [38.5% vs. 5.8%, HR 9.75 (3.54; 30.4), p < 0.001]. Superficial, partial-thickness resections were associated with decreased risk [(4.2% vs. 36.2%), HR 0.08 (0.02; 0.24), p < 0.001]. Factors associated with major complications (8.5%) were blood loss [250 (100; 400) vs. 100 (50.0; 200) mls, p = 0.03], open surgery [31.6% vs. 4.9%, HR 8.74 (2.36; 32.9), p = 0.001], stoma formation [42% vs. 3.3%, HR 20.3 (5.41; 90.0), p < 0.001], and segmental colectomy [28.2% vs. 0.9%, HR 34.6 (6.25; 876), p < 0.001]. Partial-thickness resection was associated with decreased risk ([.05% vs. 23.4%, HR 8.74 (2.36; 32.9), p < 0.001]. 19.1% experienced recurrence. Open surgery [5.2% vs. 21.3%, HR 0.14 (0.02; 1.05), p = 0.027] and superficial partial thickness excision [23.4% vs. 10.6%, HR 2.86 (1.08; 7.59), p = 0.027] were associated. Segmental resection was associated with decreased recurrence risk [7.6% vs. 23.5%, HR 0.27 (0.08; 0.91), p = 0.024]. CONCLUSION: Limiting resection to partial-thickness or full-thickness disc excision compared to bowel resection may improve complications but increase recurrence risk.

Peristomal skin complications (PSCs) are relatively common in ostomy patients, particularly in those with ileostomies. Non-healing irritation presents a clinical challenge and leads to pain and impaired quality of life for patients. METHODS: The cases of four ileostomy patients experiencing severe, challenging PSCs refractory to appliance changes, conventional dressings and barrier creams are discussed. FINDINGS: The cases of one male and one female patient with an end ileostomy post-subtotal colectomy for ulcerative colitis, one female with a defunctioning ileostomy post-anterior resection for sigmoid carcinoma and one male with an end ileostomy with a complex Crohn's surgical history are described. Two puffs of a 250 mcg metered dose beclometasone inhaler were applied to the affected skin once or twice daily. Treatment ranged from 6 to 21 days. Complete resolution was seen in all cases. CONCLUSION: Topical use of a beclometasone inhaler was effective for severe peri-ileostomy PSC secondary to four different aetiologies. Further studies are warranted to determine the effectiveness of this treatment in a larger patient cohort.

PURPOSE: Colorectal cancer patients are commonly considered a single entity in outcomes studies. This is particularly true for quality of life (QOL) studies. This study aims to compare oncologic and QOL outcomes between right colon, left colon, and rectal cancer in patients operated on in a single high-volume institution. METHODS: A prospectively maintained database was queried to identify patients with pathological stages I-III colorectal adenocarcinoma electively operated on with curative intent between 2000 and 2010. Patient characteristics, perioperative and oncologic outcomes, and QOL were compared according to cancer location. RESULTS: Two-thousand sixty-five (606 right colon cancer [RCC], 366 left colon cancer [LCC], and 1093 rectal cancer [RC]) patients met the inclusion criteria. LCC had better overall survival (OS) and disease-free survival (DFS) in the non-adjusted analysis (p < 0.001) and better OS in multivariate analysis adjusted by age, gender, ASA, chemotherapy, and pathological stage (p = 0.024). Although RCC had worse OS and DFS in non-adjusted survival analysis than LCC and RC, when adjusted for the factors above, RCC had better survival outcomes than RC, but not LCC. COX regression analysis showed age (p < 0.001), gender (p = 0.016), ASA (p < 0.001), pathological stage (p < 0.001), adjuvant chemotherapy (p = 0.043), and cancer location (p = 0.024) were independently associated with OS. Age (p < 0.001), gender (p = 0.030), ASA (p = 0.004), and pathological stage (p < 0.001) were independently associated with DFS. Patients with RC reported more sexual dysfunction and work restrictions than colon cancers (p = 0.015 and p < 0.001, respectively). CONCLUSION: In an adjusted multivariate analysis, colon cancers demonstrated better survival outcomes when compared to rectal cancers.

PURPOSE: Laparoscopic surgery for complicated Crohn's (CD) is often technically challenging. Previous studies are limited by the comparison of heterogeneous cohorts of patients undergoing laparoscopic vs open surgery. We aimed to compare perioperative and long-term outcomes of matched patients undergoing laparoscopic and open colonic and ileocolonic resection. Primary outcomes were operative time, blood loss, and complications. Long-term outcomes were subsequent intraabdominal CD surgery, incisional hernia repair, and stoma reversal rates. METHODS: Laparoscopic and open CD patients were 1:1 propensity score matched on age, body mass index, sex, indication, ASA grade, prior abdominal surgery, and postoperative Crohn's medication use based on the laparoscopic approach. RESULTS: A total of 906 patients underwent surgery for complex CD. After propensity matching, 386 were analyzed (193 open/193 lap, 51.3% male, mean age 33.9 + / - 12.6). Mean follow-up was 9.8 (range 7.9-12.1) years. Length of stay [(LOS) 6 (4, 8) vs 8 (5, 11) days, p < 0.001] and operative time [154 (110, 216) vs 176 (126, 239) min, p = 0.03] were shorter in the laparoscopic group. There was no difference in other complications or mortality. After adjusting for postoperative medications, no association was found between operative approach and subsequent intra-abdominal operation or incisional hernia repair. Laparoscopic patients were less likely to have postoperative sepsis [OR 0.40 (0.18, 0.91), p = 0.03]. CONCLUSION: In the setting of complicated Crohn's, in matched cohorts, laparoscopic surgery is associated with reduced operative times and LOS. Mortality, reoperation, and symptomatic hernia rates were equivalent to open surgery. Patients undergoing laparoscopic surgery are less likely to experience postoperative sepsis.

AIM: In low rectal cancers without sphincter involvement a permanent stoma can be avoided without compromising oncological safety. Functional outcomes following coloanal anastomosis (CAA) compared to abdominoperineal excision (APR) may be significantly different. This study examines all available comparative quality of life (QoL) data for patients undergoing CAA versus APR for low rectal cancer. METHODS: Published studies with comparative data on QoL outcomes following CAA versus APR for low rectal cancer were extracted from electronic databases. The study was registered with PROSPERO and adhered to PRISMA (Preferred Reporting Items in Systematic Reviews and Meta-analyses) guidelines. Data was combined using random-effects models. RESULTS: Seven comparative series examined QoL in 527 patients. There was no difference in the numbers receiving neoadjuvant radiotherapy in the APR and CAA groups (OR: 1.19, 95% CI: 0.78-1.81, p = 0.43). CAA was associated with higher mean scores for physical functioning(std mean diff -7.08, 95% CI: -11.92 to -2.25, p = 0.004) and body image (std. mean diff 11.11, 95% CI: 6.04-16.18, p < 0.0001). Male sexual problems were significantly increased in patients who had undergone APR compared to CAA (std. mean diff -16.20, 95% CI: -25.76 to -6.64, p = 0.0009). Patients who had an APR reported more fatigue, dyspnoea and appetite loss. Those who had a CAA reported higher scores for both constipation and diarrhoea. DISCUSSION: It is reasonable to offer a CAA to motivated patients where oncological outcomes will not be threatened. QoL outcomes appear to be superior when intestinal continuity is maintained, and permanent stoma avoided.

BACKGROUND: Right iliac fossa (RIF) pain is a common indication for laparoscopy to diagnose and treat appendicitis. When a macroscopically normal appendix is found, there is no standard consensus regarding excision. Some surgeons remove the appendix due to the risk of microscopic inflammation and to avoid a future, repeat laparoscopy for possible appendicitis. Alternatively, others leave the appendix in situ to avoid morbidity from a potentially unnecessary procedure. We aimed to evaluate the outcomes of patients with macroscopically normal appendices left in situ. METHODS: All emergency laparoscopies without appendicectomy between January 1st 2010- December 31st 2020 were identified from theatre records. All operative notes were individually evaluated and comments on the macroscopic appearance of the appendix and any intra-operative pathology were recorded. Only patients undergoing laparoscopy for suspected appendicitis with macroscopically normal appendices were included. RESULTS: A total of 120 patients [median age 21.68 (range 9-90.8) years] were included. The cohort was predominantly female (n=105, 87.5%). Forty-eight patients (40.0%) had a positive finding during index laparoscopy. During a median duration of 94.5 (range 8-131) months' follow-up, 16 patients (13.33%) underwent a repeat laparoscopy for recurrent RIF pain. Thirteen (10.8% of total cohort) subsequently underwent an appendicectomy. Histology confirmed acute appendicitis in six cases (4.17% of entire cohort). On subanalysis of smaller cohort, index laparoscopies with no positive findings (n=72), nine patients (12.5%) underwent appendicectomy with two (2.7%) appendices demonstrating appendicitis on histological examination. CONCLUSION: 87% of the total cohort with a normal appendix at laparoscopy for RIF pain did not undergo further laparoscopy. Less than 5% of the total cohort and 2.7% of subanalysis cohort had an appendicectomy for histologically-proven appendicitis within the follow-up period. From the evidence in this study, we conclude that leaving the appendix in situ unless macroscopically inflamed is a viable alternative to excision.

Total proctocolectomy and ileal pouch anal anastomosis (IPAA) is the gold standard surgical treatment for the majority (â¼90%) of ulcerative colitis (UC) patients. In cases of carefully selected Crohn's colitis patients without small bowel or perianal involvement an "intentional IPAA" may be a viable option for disease resection and restoration of intestinal continuity. More commonly, Crohn's is incidentally found either in the resection specimen or, more commonly, when inflammatory complications subsequently arise after pouch construction for UC or indeterminate colitis. These incidental Crohn's pouches may be diagnosed early or late period post-IPAA. Crohn's may manifest within the pouch, in the proximal small bowel, and/or distally in the rectal cuff or anus. Like intestinal Crohn's, Crohn's disease of the pouch may be of an inflammatory, fibrostenosing, or fistulizing phenotype. Treatment depends on the phenotype and includes medical treatment, most commonly in the form of tumor necrosis factor inhibitor medications; however, the newer small molecules offer a potential treatment for these patients. Surgery first entails treating the sequelae of Crohn's and is typically staged. In up to 60% of Crohn's pouches, particularly in fistulizing disease and/or recalcitrant perianal disease, the pouch fails and must be defunctioned or excised. In patients with Crohn's pouches in situ long term, outcomes including quality of life are comparable to patients who underwent IPAA for UC.
RESUMO
BACKGROUND: Minimum rest is mandated in high stake industries such as aviation. The current system of healthcare provision permits on-call surgeons to work in sleep deprived states when performing procedures. Fatigue has been demonstrated to negatively affect performance. This study aimed to explore measurements of sleep deprivation and their impact on simulated performance. METHODS: This was a single site study conducted between September 2019 and February 2020. Surgical trainee and consultants were conveniently sampled from a single site. All testing was done between 7 AM and 9 AM. Participants completed electroencephalogram testing using a modified Multiple Sleep Latency Test testing for objective sleep measurement, the Pittsburgh Sleep Quality Index, Chalder Fatigue Scale and Epworth Sleepiness Scale for subjective sleep measurement. The Psychomotor Vigilance Task and the SIMENDO simulated tasks were used for standardized performance assessment. RESULTS: Surgeons entered sleep in 6 min, on average pre-call. This significantly decreased to an average of 164 s post-call (P = 0.016). Pittsburgh Sleep Quality Index scoring was 5, indicating poor baseline sleep quality. There was higher self-reported fatigue and sleepiness in post-call states. Performance decrements were noted in cognitive performance reaction time and aspects of technical instrument proficiency. CONCLUSIONS: Surgeons are objectively sleep deprived pre-call according to internationally recognized guidelines. This sleep deprivation increases significantly in post-call states. Tasks with higher cognitive demands showed greater levels of diminished performance compared to those with lower cognitive demands. Current models of provision of surgical on-call are not conducive to optimizing sleep in surgeons. Prioritization of workload in post-call states, focusing on preserving individuals cognitive resources and utilizing lower cognitively demanding aspects of work is likely to have positive impacts on performance outcomes.

PURPOSE: The shift in the national focus and allocation of resources to the management of COVID19 has led to significant changes to surgical practice including the delay of elective surgery. The aim of this study was to explore the implications of such changes on surgeons. METHOD: Using a qualitative study design, semi-structured interviews were conducted with general surgery consultants and non-consultant hospital doctors from a major tertiary hospital in the Dublin region between March-May 2020. Data collection proceeded iteratively using a thematic analysis approach with quality controls such as memoing and collaborative analysis. RESULTS: Fourteen surgeons (8 male, 6 female) were interviewed. The majority (n = 11, 78.6%) were NCHDs. Significant themes determined included 'impacts' on a variety of constructs such as performance, self-reported fatigue and wellbeing. Training themes elucidated included the effects of the cancellation of elective admissions on reduced operative exposure for trainees. Senior surgical staff were particularly focused on increased complexity in patient management. New policy requirements such as personal protective equipment use and novel rotas have had implications for aspects of work engagement. The pandemic and subsequent national restrictions imposed has afforded opportunities for improved well-being but also resulted in greater solitude in surgeons. CONCLUSIONS: Rhetoric surrounding fatigue management and virus control dominates the conversation on the relationship between COVID-19 and surgery. Tipping the balance back to parity of fatigue management with service delivery in surgery will be key for sustainability of the surgical workforce.

BACKGROUND: The management of diverticulitis is compromised by difficulty in identifying patients who require surgery for recurrent or persistent disease. Here, we introduce the concept of multifocal diverticulitis (MFD), characterized by multiple episodes of diverticulitis occurring at different locations within the colon. AIMS: To compare clinical characteristics, success of surgical management, and colonic transcriptomes of MFD patients to patients with conventional unifocal diverticulitis (UFD). METHODS: This retrospective study included 404 patients with CT-confirmed diverticulitis episodes. Patients with diverticulitis seen in at least two different colonic locations were classified as the MFD group and compared to the UFD group based on number of episodes, sites of disease, family history, surgeries performed, and postoperative recurrence. RNA-seq was conducted on full-thickness colonic tissues of ten MFD and 11 UFD patients. RESULTS: Twenty-eight patients (6.9%) with MFD were identified. MFD patients had more diverticulitis episodes and were more likely to have positive family history, have right-sided disease, require surgery, and have recurrence after surgery. All MFD patients treated with segmental resection had recurrence, while recurrence was less common in patients undergoing more extensive surgery (P < 0.001). Using RNA-seq, we identified 69 genes that were differentially expressed between MFD and UFD patients. Significantly down-regulated genes were associated with immune response pathways. CONCLUSIONS: MFD appears to be a more severe subset of diverticulitis with a possible genetic component. Transcriptomic data suggest that MFD may be associated with alteration of the immune response.

AIM: Although commonly the first port of call for medical information, the internet provides unregulated information of variable quality. We aimed to evaluate commonly accessed web-based patient information on diverticulitis using validated and novel scoring systems. METHODS: The top internet search engines (Google/Bing/Yahoo) were queried using the keyword 'diverticulitis.' The first 20 websites from each were graded using the DISCERN and Journal of the American Medical Association (JAMA) benchmark criteria. A novel diverticulitis-specific score was devised and applied. RESULTS: Thirty-six unique websites were identified. The mean total DISCERN score for all websites was 39.92 ± 12.44 (range = 18-62). No website achieved the maximum DISCERN score of 75. The mean JAMA and diverticulitis scores were 2.5 ± 1.08 (maximum possible score = 4) and 11.08 ± 4.17 (19 points possible) respectively. Fourteen (35.9%) and 20 (51.2%) did not provide the date of last update and authorship respectively. Thirty-three (84.6%) mentioned surgery as a treatment option; however, the majority (69.7%) did not describe the surgery or the possibility of a stoma. All except two described disease symptoms. Only ten (25.64%) provided information on when to seek further medical advice or help. CONCLUSION: Web-based information on diverticulitis is of variable content and quality. The majority of top websites describe disease symptoms and aetiology; however, information to prompt seeking medical attention if required, descriptions of surgical procedures and the possibility of stoma creation are poorly described in the majority of websites. These findings should be highlighted to patients utilising the internet to obtain information on diverticulitis.

BACKGROUND: Diverticulitis (DD) and Crohn's disease (CD) have overlapping features including bowel structuring, inflammation, and infection. Tumor necrosis superfamily 15 (TNFSF15) is an immunoregulatory, anti-angiogenic gene. CD has been previously associated with a haplotype of five TNFSF15 single-nucleotide polymorphism alleles: rs3810936 (G allele), rs6478108 (A), rs6478109 (G), rs7848647 (G), and rs7869487 (A). We aimed to determine the TNFSF15 risk haplotype for DD versus controls with a subgroup analysis of youthful DD patients (aged ≤55 y) versus older controls (aged ≥55 y). METHODS: A total of 148 diverticulitis patients (90 aged ≤55 y) and 200 controls (87 aged ≥55 y) were genotyped using our custom-designed Illumina Veracode microarray chip. Genotypes from rs3810936, rs6478108, rs6478109, rs7848647, rs7869487 and two additional TNFSF15 single nucleotide polymorphisms, rs3810936 and rs11554257, were analyzed. PHASE version 2.1, R with HaploStats and the Broad Institute's Haploview program were used for statistics and imputed haplotype frequency. Permutation corrected for multiple comparisons. RESULTS: The CD GAGGA haplotype was significantly associated with diverticulitis (P = 0.03) in the all DD versus all controls comparison. A second haplotype, rs6478108 (A), rs6478109 (G), rs7869487 (A), and rs4263839 (G), was also associated with DD in this cohort (P = 0.025). A third haplotype rs6478108 (A), rs6478109 (G), rs7848647 (G) and rs7869487 (A), rs4263839 (G) was demonstrated in the DD < 55 versus controls >55 comparison (P = 0.045). CONCLUSIONS: Distinct but overlapping TNFSF15 haplotypes were demonstrated in diverticulitis patients versus healthy controls when compared with the known Crohn's risk haplotype suggesting similar but distinct genetic predispositions. This study strengthens the role for a genetic predisposition to diverticulitis that involves the TNFSF15 gene.

AIM: The definitive diagnosis of acute appendicitis (AA) requires histopathological examination. Various clinical diagnostic scoring systems attempt to reduce negative appendectomy rates. The most commonly used in Western Europe and the USA is the Alvarado score. The Raja Isteri Pengiran Anak Saleha appendicitis (RIPASA) score achieves better sensitivity and specificity in Asian and Middle Eastern populations. We aimed to determine the diagnostic accuracy of the RIPASA score in Irish patients with AA. METHODS: All patients who presented to our institution with right iliac fossa pain and clinically suspected AA between January 1 and December 31, 2015, were indentified from our hospital inpatient enquiry database and retrospectively studied. Operating theatre records and histology reports confirmed those who underwent a non-elective operative procedure and the presence or absence of AA. SPSS version 22 was used for statistical analysis. Standard deviation is provided where appropriate. RESULTS: Two hundred eight patients were included in the study (106/51% male, mean age 22.7 ± 9.2 years). One hundred thirty-five (64.9%) had histologically confirmed AA (mean symptom duration = 36.19 ± 15.90 h). At a score ≥7.5, the previously determined score most likely associated with AA in Eastern populations, the RIPASA scoring system demonstrated a sensitivity of 85.39%, specificity of 69.86%, positive predictive value of 84.06%, negative predictive value of 72.86% and diagnostic accuracy of 80% in our cohort. CONCLUSION: The RIPASA score is a useful tool to aid in the diagnosis of acute appendicitis in the Irish population. A score of ≥7.5 provides sensitivity and specificity exceeding that previously documented for the Alvarado score in Western populations. WHAT DOES THIS PAPER ADD TO THE LITERATURE?: This is the first study evaluating the utility of the RIPASA score in predicting acute appendicitis in a Western population. At a value of 7.5, a cut-off score suggestive of appendicitis in the Eastern population, RIPASA demonstrated a high-sensitivity, specificity, positive predictive value and diagnostic accuracy in our cohort and was more accurate than the commonly used Alvarado score.
