Abstract
INTRODUCTION Intra-abdominal abscesses complicating Crohn's disease (CD) present an additional challenge as their presence can contraindicate immunosuppressive treatment whilst emergency surgery is associated with high stoma rate and complications. Treatment options include a conservative approach, percutaneous drainage, and surgical intervention. The current multicentre study audited the short-term outcomes of patients who underwent preoperative radiological drainage of intra-abdominal abscesses up to 6 weeks prior to surgery for ileocolonic CD. METHODS This is a retrospective, multicentre, observational study promoted by the Italian Society of Colorectal Surgery (SICCR), including all adults undergoing ileocolic resection for primary or recurrent CD from June 2018 to May 2019. The outcomes of patients who underwent radiological guided drainage prior to ileocolonic resection were compared to the patients who did not require preoperative drainage. Postoperative morbidity within 30 days of surgery was the primary endpoint. Postoperative length of hospital stay (LOS) and anastomotic leak rate were the secondary outcomes. RESULTS Amongst a group of 575 included patients who had an ileocolic resection for CD, there were 36 patients (6.2%) who underwent abscess drainage prior to surgery. Postoperative morbidity (44.4%) and anastomotic leak (11.1%) were significantly higher in the group of patients who underwent preoperative drainage. CONCLUSIONS Patients with Crohn's disease who require preoperative radiological guided drainage of intra-abdominal abscesses are at increased risk of postoperative morbidity and septic complications following ileocaecal or re-do ileocolic resection.

Abstract
Background and aims Diversion proctocolitis (DP) is a non‐specific mucosal inflammation arising in the defunctionalized colon and/or rectum following faecal diversion (colostomy, ileostomy). Differential diagnosis of DP from the underlying disease in patients with inflammatory bowel diseases (IBD) is often unclear. As a result, it might be difficult to undertake any specific treatment. We aimed to systematically review the literature evidence on DP in IBD patients. Methods For this qualitative systematic review, we searched PubMed, EMBASE and Scopus to identify all studies published until July 2021 including IBD patients affected by DP. Results Overall, 37 papers published between 1982 and 2021 were included. A total of 1.211 IBD patients were included: 613 UC (50.6%), 524 CD (43.3%), 66 IBD‐unclassified (IBD‐U) (5.4%), 8 unspecified patients (0.7%). Most patients with DP are asymptomatic, although inflammation is detectable in almost all patients with a rectal stump. Reduced short‐chain fatty acids and an altered microbiome, may trigger mucosal inflammation and have been proposed as causing factors. An increased risk of developing cancer on DP has been reported in patients with a history of previous dysplasia/cancer. Conclusions The etiopathogenesis of DP is still unknown. The efficacy of mesalamine, corticosteroids or short‐chain fatty acids has not been proven by randomized trials yet. Since the incidence of cancer of the rectal stump can reach 4.5 per 1.000 diverted patients‐year, IBD patients undergoing subtotal colectomy with end‐ileostomy should undergo close endoscopic surveillance, being eventually counseled for surgery with or without the restoration of the intestinal continuity.

Abstract
Background Stoma-reversal surgery is associated with high postoperative morbidity, including wound complications and surgical-site infections (SSIs). This study aims to assess whether the application of negative-pressure wound therapy (NPWT) can improve wound healing compared with conventional wound dressing. Methods This was a single-centre, superiority, open-label, parallel, individually randomized controlled trial. Patients undergoing stoma reversal were randomized (1 : 1) to receive NPWT or conventional wound dressing. The primary endpoint of the study was the rate of wound complications and SSIs after stoma closure. The secondary endpoints were postoperative wound pain, rate of wound healing after 30 days from stoma closure, and wound aesthetic satisfaction. Results Between June 2019 and January 2021, 50 patients were allocated to the NPWT group (all received NPWT, 49 were analysed); 50 patients were allocated to the conventional wound dressing group (48 received the treatment, 45 were analysed). No significant difference was found in wound-complication rate (10 per cent NPWT versus 16 per cent controls; odds ratio 0.61 (95 per cent c.i. 0.18 to 2.10), P = 0.542) and incisional SSI rate (8 per cent NPWT versus 7 per cent controls; odds ratio 1.24 (95 per cent c.i. 0.26 to 5.99), P = 1.000). The NPWT group showed less pain, higher aesthetic satisfaction (P < 0.0001), and a higher proportion of wound healing (92 versus 78 per cent; P = 0.081) compared with the control group. Conclusion NPWT does not reduce the incidence of SSI after stoma-reversal surgery compared with conventional wound dressing. However, NPWT improved the healing of uninfected wounds, reduced wound pain and led to better aesthetic outcomes. Registration number: NCT037812016 (clinicaltrials.gov).

Abstract
PURPOSE OF REVIEW In this study we present the evidence based management for patients hospitalized for UC with a special focus on the synergic approach of the two key actors of the inflammatory bowel disease multidisciplinary team (IBD-MDT): gastroenterologist and surgeon. RECENT FINDINGS Focused treatment by a specialized IBD-MDT and early involvement of the colorectal surgeon in the management of hospitalized ulcerative colitis patients is advocated. The colectomy rate has not changed over the years. Moreover delayed surgery after admission is burden by increase complication and mortality. Thus, it is pivotal to identify the patients who are likely to undergo surgery, by mean of predictors of outcome, and to not prolong ineffective medical treatment. The perfect timing based on clinical close monitoring is crucial. Up to 25% of patients with ulcerative colitis (UC) may require hospitalization. The aim of admission is to evaluate severity of the disease, exclude infections and establish proper treatment while monitoring the response. During admission, the patient has to be closely observed for the possible development of toxic megacolon or perforation, which should prompt emergency colectomy. Up to 30% of UC patients will fail to respond to initial intravenous corticosteroid. Non responder or partial responder to medical therapy should be evaluated for timely surgery or could be considered for rescue medical therapy.

Abstract
BACKGROUND while interest on early-onset colorectal cancer (age ≤49) is on the rise, studies on early-onset rectal cancer (EORC) are limited. The aim of this study was to compare predictors for disease progression/recurrence between sporadic EORC and late-onset RC patients (LORC). METHODS 163 EORC and 830 LORC operated between January 1st, 2010 and April 30th, 2021 at a tertiary center were included. Demographics, tumor characteristics, microsatellite status, gene mutations (KRAS, BRAF, NRAS, PI3Kca) and oncologic outcomes were compared. A Cox proportional hazards regression analysis was performed to ascertain the effect of variables on recurrence/progression and death. Recurrence/Progression free survival (R/PFS) and cancer specific survival (CSS) were analyzed by the Kaplan-Meier estimator. RESULTS Mean age of EORC was 42.16, (46% aged 45-49). A majority of EORC patients had a family history for CRC (p = 0.01) and underwent total neoadjuvant treatment (p = 0.01). EORC patients showed a higher rate of low-grade tumor differentiation (p < 0.0001), stage III-IV (p = 0.001), microsatellite instability (p = 0.02), locoregional nodal (p = 0.001) and distant metastases (p < 0.0001). Accordingly, more EORC patients underwent adjuvant treatment (p < 0.0001). Mutations were mostly reported among LORC cases (p = 0.04), whereas EORC patients showed a worse R/PFS (p = 0.02), even at stage I (p = 0.04). CSS did not differ (p = 0.11) across groups. Multivariate analysis indicated age of onset (p = 0.04) was an independent predictor for progression/recurrence. CONCLUSIONS Age of onset was shown to be an independent unfavorable predictor. Delayed diagnosis could explain this effect in the more advanced stages, while the worse outcomes in stage I may suggest a more aggressive disease behavior.

Abstract
Objectives Intraoperative fluorescence imaging is currently used in a variety of surgical fields for four main purposes: assessing tissue perfusion; identifying/localizing cancer; mapping lymphatic systems; and visualizing anatomy. To establish evidence-based guidance for research and practice, understanding the state of research on fluorescence imaging in different surgical fields is needed. We evaluated the evidence on fluorescence imaging for perfusion assessments using the Idea, Development, Exploration, Assessment, Long Term Study (IDEAL) framework, which was designed for describing the stages of innovation in surgery and other interventional procedures. Design Narrative literature review with analysis of IDEAL stage of each field of study. Setting All publications on intraoperative fluorescence imaging for perfusion assessments reported in PubMed through 2019 were identified for six surgical procedures: coronary artery bypass grafting (CABG), upper gastrointestinal (GI) surgery, colorectal surgery, solid organ transplantation, reconstructive surgery, and cerebral aneurysm surgery. Main outcome measures The IDEAL stage of research evidence was determined for each specialty field using a previously described approach. Results 196 articles (15 003 cases) were selected for analysis. Current status of research evidence was determined to be IDEAL Stage 2a for upper GI and transplantation surgery, IDEAL 2b for CABG, colorectal and cerebral aneurysm surgery, and IDEAL Stage 3 for reconstructive surgery. Using the technique resulted in a high (up to 50%) rate of revisions among surgical procedures, but its efficacy improving postoperative outcomes has not yet been demonstrated by randomized controlled trials in any discipline. Only one possible adverse reaction to intravenous indocyanine green was reported. Conclusions Using fluorescence imaging intraoperatively to assess perfusion is feasible and appears useful for surgical decision making across a range of disciplines. Identifying the IDEAL stage of current research knowledge aids in planning further studies to establish the potential for patient benefit.

Abstract
AIM Surgery is indicated in selected patients with inflammatory bowel disease (IBD). However, due to a negative perception, surgery may be delayed, leading to possible unfavourable outcomes. The aim of this work was to investigate patients' perceptions of surgery and the impact on reported outcomes. METHOD An international multilingual online survey was used to query IBD patients' experiences of surgery, information sources, expectations and concerns, quality of life (QoL) and feelings. RESULTS The survey was completed by 425 of 510 participants. Crohn's disease was more frequent (61%) than ulcerative colitis (36%). Most patients primarily learned about surgery from their gastroenterologist and were informed of the risks and benefits by the surgeon. In almost one-third of patients indication for surgery was not a shared decision between gastroenterologist and surgeon. Seventy per cent of patients naïve to surgery were not aware of any surgical options. The majority of patients (80%) perceived surgery as the last option after many medical treatments rather than an alternative therapeutic option (20%). Sixteen per cent of patients obtained their primary information from the Internet, while 82.4% used the Internet to obtain additional information. Fear of surgical complications was cited by 73% of patients, while relief from symptoms was indicated by 31%. Most patients coped with their stoma better than expected or as they expected. Negative feelings decreased after surgery, while a lasting improvement in positive feelings and QoL was reported. CONCLUSION Despite the negative perception of surgery and the delayed involvement of surgeons as a source of information and in the decision-making process, the majority of respondents experienced positive outcomes from surgery, including improvement QoL and acceptance of the stoma.

Abstract
Importance The incidence of early-onset colorectal cancer (younger than 50 years) is rising globally, the reasons for which are unclear. It appears to represent a unique disease process with different clinical, pathological, and molecular characteristics compared with late-onset colorectal cancer. Data on oncological outcomes are limited, and sensitivity to conventional neoadjuvant and adjuvant therapy regimens appear to be unknown. The purpose of this review is to summarize the available literature on early-onset colorectal cancer. Observations Within the next decade, it is estimated that 1 in 10 colon cancers and 1 in 4 rectal cancers will be diagnosed in adults younger than 50 years. Potential risk factors include a Westernized diet, obesity, antibiotic usage, and alterations in the gut microbiome. Although genetic predisposition plays a role, most cases are sporadic. The full spectrum of germline and somatic sequence variations implicated remains unknown. Younger patients typically present with descending colonic or rectal cancer, advanced disease stage, and unfavorable histopathological features. Despite being more likely to receive neoadjuvant and adjuvant therapy, patients with early-onset disease demonstrate comparable oncological outcomes with their older counterparts. Conclusions and Relevance The clinicopathological features, underlying molecular profiles, and drivers of early-onset colorectal cancer differ from those of late-onset disease. Standardized, age-specific preventive, screening, diagnostic, and therapeutic strategies are required to optimize outcomes.

Abstract
BACKGROUND Rectal cancer in adolescents and young adults (age ≤39) is increasing. Early diagnosis is a challenge in this subset of patients. OBJECTIVE This study aims to analyze the presentation pattern and outcomes of sporadic rectal cancer in adolescents and young adults. DESIGN This is a retrospective study. SETTING This study was conducted at 3 European tertiary centers. PATIENTS Data on adolescents and young adults operated on for sporadic rectal cancer (January 2008 through October 2019) were analyzed. To compare outcomes, adolescents and young adults were matched to a group of patients aged ≥40 operated on during the same period. MAIN OUTCOME MEASURES The primary outcomes measured were clinical presentation and long-term outcomes. RESULTS Sporadic rectal cancers occurred in 101 adolescents and young adults (2.4%; mean age, 33.5; range, 18-39); 51.5% were male, and a smoking habit was reported by 17.8% of patients. The rate of a family history for colorectal cancer was 25.7%, and of these patients, 24.7% were obese. Diagnosis based on symptoms was reported in 92.1% patients, and the mean time from first symptoms to diagnosis was 13.7 months. The most common symptom at diagnosis was rectal bleeding (68.8%), and 12% and 34% of the adolescents and young adults presented with locally advanced or metastatic disease at diagnosis. Consequently, 68.3% and 62.4% adolescents and young adults received neoadjuvant and adjuvant treatments. The rate of complete pathological response was 24.1%; whereas 38.6% patients had stage IV disease, and 93.1% were microsatellite stable. At a mean follow-up of 5 years, no difference in cancer-specific survival, but a lower disease-free survival was reported in adolescents and young adults (p < 0.0001) vs the matched group. Adolescents and young adults with stages I to II disease had shorter cancer-specific survival and disease-free survival (p = 0.006; p < 0.0001); with stage III disease, they had a shorter disease-free survival (p = 0.01). LIMITATIONS This study was limited by its observational, retrospective design. CONCLUSIONS The significantly delayed diagnosis in adolescents and young adults may have contributed to the advanced disease at presentation and lower disease-free survival, even at earlier stages, suggesting a higher metastatic potential than in older patients.

CNCER DE RECTO EN PACIENTES ADOLESCENTES Y ADULTOS JVENES CUADRO DE PRESENTACIN CLNICA Y COMPARACIN DE DESENLACES POR CASOS EMPAREJADOS ANTECEDENTES:El cáncer de recto en adolescentes y adultos jóvenes (edad ≤ 39) está aumentando. El diagnóstico temprano es un desafío en este subgrupo de pacientes.OBJETIVO:Analizar el cuadro de presentación y los desenlaces en adolescentes y adultos jóvenes con cáncer de recto esporádico.DISEÑO:Estudio retrospectivo.ÁMBITO:Tres centros europeos de tercer nivel.PACIENTES:Se analizaron los datos de adolescentes y adultos jóvenes operados de cáncer de recto esporádico (enero de 2008 - octubre de 2019). Para comparar los desenlaces se emparejó a adolescentes y adultos jóvenes con un grupo de pacientes mayores de 40 años operados en el mismo período de tiempo.PRINCIPALES VARIABLES ANALIZADAS:Cuadro clínico, resultados a largo plazo.RESULTADOS:Los cánceres de recto esporádicos en adolescentes y adultos jóvenes fueron 101 (2,4%, edad media: 33,5, rango 18-39). El 51,5% eran hombres, el 17,8% de los pacientes fumaba. El 25,7% tentía antecedentes familiares de cáncer colorrectal. El 24,7% eran obesos. El diagnóstico con base en los síntomas se informó en el 92,1% de los pacientes, el tiempo promedio desde los primeros síntomas hasta el diagnóstico fue de 13,7 meses. El síntoma más común en el momento del diagnóstico fue el sangrado rectal (68,8%). 12% y 34% de adolescentes y adultos jóvenes presentaron enfermedad localmente avanzada o metastásica en el momento del diagnóstico. Por lo tanto, el 68,3% y el 62,4% de adolescentes y adultos jóvenes recibieron neoadyuvancia y adyuvancia. La tasa de respuesta patológica completa fue del 24,1%; mientras que el 38,6% estaban en estadio IV. El 93,1% eran microsatelite estable. Con una media de seguimiento de 5 años, no se observaron diferencias en la sobrevida específica del cáncer, pero se informó una menor sobrevida libre de enfermedad en adolescentes y adultos jóvenes (p <0,0001) frente al grupo emparejado. Los adolescentes y adultos jóvenes en estadios I-II tuvieron una sobrevida específica por cáncer y una sobrevida libre de enfermedad más corta (p = 0,006; p <0,0001); el estadio III tuvo una sobrevida libre de enfermedad más baja (p = 0,01).LIMITACIONES:Diseño observacional y retrospectivo.CONCLUSIONES:El diagnóstico notablemente demorado en adolescentes y adultos jóvenes puede contribuir a la presentación de una enfermedad avanzada y a una menor sobrevida libre de enfermedad, incluso en estadios más tempranas, lo cual implica un mayor potencial metastásico en comparación con pacientes mayores.

Abstract
BACKGROUND in the literature on rectal cancer (RC) surgery many studies have focused on the quality of total mesorectal excision (TME) dissection, while there is a scarcity of comparative data on transection and anastomosis. No anastomosis has so far proved to be superior to any other. The aim of this study was to compare anastomotic leak (AL) rates between conventional laparoscopic double-stapled (DS), transanal total mesorectal excision (TaTME) and Transanal Transection and Single-Stapled anastomosis (TTSS) techniques. METHODS consecutive mid-low RC patients undergoing elective laparoscopic TME with stapled anastomosis and protective stoma, by either DS, TaTME or TTSS techniques were retrieved from a prospectively collected database. RESULTS 127 DS; 100 TaTME and 50 TTSS were included. Demographics, distance of the tumor from anal verge and neoadjuvant therapy were comparable. Operative time was longer in TaTME over DS and TTSS (p < 0.0001). More 90-days complications occurred in DS group vs TTSS (p = 0.029). The AL rate was 17.5% in DS, 6% in TaTME and 2% in TTSS group (p = 0.005). AL grade was: one B (2%) in TTSS; 2 grade B (2%) and 4 grade C (4%) in TaTME; 6 grade A (4.7%), 7 grade B (5.5%) and 9 grade C (7.1%) in DS group. Reintervention rate after AL was higher in DS group over TTSS (12.6% vs 2%; p = 0.003). The rate of stoma closure, pathology data and margin positivity did not differ. CONCLUSIONS TTSS strategy is feasible, safe and leads to very low AL rates after TME for RC.

Abstract
INTRODUCTION To explore the reported variability in the surgical management of ileocolonic Crohn' s disease and identify areas of standard practice, we present this study which aims to assess how different colorectal surgeons with a subspecialty interest in inflammatory bowel disease (IBD) surgery may act in different clinical scenarios of ileocolonic Crohn's disease. METHODS Anonymous videos demonstrating the small bowel walkthrough and anonymised patients' clinical data, imaging and pathological findings were distributed to the surgeons using an electronic tool. Surgeons answered on operative strategy, bowel resections, management of small bowel mesentery, type of anastomosis and use of stomas. RESULTS Eight small bowel walkthrough videos were registered and 12 assessors completed the survey with a questionnaire completion rate of 87.5%. There was 87.7% agreement in the need to perform an ileocolonic resection. However, the agreement for the need to perform associated surgical procedures such as strictureplasties or further bowel resections was only 57.4%. When an anastomosis was fashioned, the side to side configuration was the most commonly used. The preferred management of the mesentery was dissection close to the bowel. CONCLUSIONS The decision on the main procedure to be performed had a high agreement amongst the different assessors, but the treatment of multifocal disease was highly controversial, with low agreement on the need for associated procedures to treat internal fistulae and the use of strictureplasties. At the same time, there was significant heterogeneity in the decision on when to anastomose and when to fashion an ileostomy.

Abstract
Outcomes of inflammatory bowel disease (IBD) patients requiring surgery during the outbreak of Coronavirus disease 19 (COVID-19) are unknown. Aim of this study was to analyse the outcomes depending on the COVID-19 status of the centre. Patients undergoing surgery in six COVID-19 treatment and one COVID-free hospitals (five countries) during the first COVID-19 peak were included. Variables associated with risk of moderate-to-severe complications were identified using logistic regression analysis. A total of 91 patients with Crohn's disease (54, 59.3%) or ulcerative colitis (37, 40.7%), 66 (72.5%) had surgery in one of the COVID-19-treatment hospitals, while 25 (27.5%) in the COVID-19-free centre. More COVID-19-treatment patients required urgent surgery (48.4% vs. 24%, p = 0.035), did not discontinue biologic therapy (15.1% vs. 0%, p = 0.039), underwent surgery without a SARS-CoV-2 test (19.7% vs. 0%, p = 0.0033), and required intensive care admission (10.6% vs. 0%, p = 0.032). Three patients (4.6%) had a SARS-CoV-2 infection postoperatively. Postoperative complications were associated with the use of steroids at surgery (Odds ratio [OR] = 4.10, 95% CI 1.14-15.3, p = 0.03), presence of comorbidities (OR = 3.33, 95% CI 1.08-11, p = 0.035), and Crohn's disease (vs. ulcerative colitis, OR = 3.82, 95% CI 1.14-15.4, p = 0.028). IBD patients can undergo surgery regardless of the COVID-19 status of the referral centre. The risk of SARS-CoV-2 infection should be taken into account.

Abstract
AIM Many factors influence the postoperative length of stay (LOS) in Crohn's disease (CD). This study aims to identify the factors associated with a prolonged LOS after ileocolic resection (ICR) for CD and to develop a scoring system to predict the postoperative LOS in CD. METHOD Patient data were collected from St Marks Hospital, London, UK, and the Humanitas Clinical and Research Center Milan, Italy, for all patients who underwent an ICR for CD from 2005 to 2017. Logistic regression was used for multivariate analysis. The scoring system was developed from the logistic regression model. The performance of the scoring system was evaluated using the area under the receiver operating characteristic curve (AUROC). RESULTS A total of 628 surgeries were included in the analysis. Eighty eight surgeries were excluded due to missing data. The remaining 543 were divided into two cohorts for the development (n = 418) and validation (n = 125) of the scoring system. The regression model was statistically significant (p < 0.0001). The statistically significant independent variables included the time since diagnosis, American Society of Anesthesiologists (ASA) grade, perioperative use of steroids, surgical access, strictureplasty and platelet count. The AUROCs for the development and validation cohorts were 0.732 and 0.7, respectively (p < 0.0001). The cut-off score suggested by Youden's index was 50, with a sensitivity of 65.6% and a specificity of 73.3%. CONCLUSION The time since diagnosis, ASA grade, steroid use, surgical access, strictureplasty and platelet count were associated with a prolonged LOS and were used to develop a scoring system.

Abstract
A limited ileocaecal resection is the most frequently performed procedure for ileocaecal CD and different anastomotic configurations and techniques have been described. This manuscript audited the different anastomotic techniques used in a national study and evaluated their influence on postoperative outcomes following ileocaecal resection for primary CD. This is a retrospective, multicentre, observational study promoted by the Italian Society of Colorectal Surgery (SICCR), including all adults undergoing elective ileocaecal resection for primary CD from June 2018 May 2019. Postoperative morbidity within 30 days of surgery was the primary endpoint. Postoperative length of hospital stay (LOS) and anastomotic leak rate were the secondary outcomes. 427 patients were included. The side to side anastomosis was the chosen configuration in 380 patients (89%). The stapled anastomotic (n = 286; 67%), techniques were preferred to hand-sewn (n = 141; 33%). Postoperative morbidity was 20.3% and anastomotic leak 3.7%. Anastomotic leak was independent of the type of anastomosis performed, while was associated with an ASA grade ≥ 3, presence of perianal disease and ileocolonic localization of disease. Four predictors of LOS were identified after multivariate analysis. The laparoscopic approach was the only associated with a reduced LOS (p = 0.017), while age, ASA grade ≥ 3 or administration of preoperative TPN were associated with increased LOS. The side to side was the most commonly used anastomotic configuration for ileocolic reconstruction following primary CD resection. There was no difference in postoperative morbidity according to anastomotic technique and configuration. Anastomotic leak was associated with ASA grade ≥ 3, a penetrating phenotype of disease and ileo-colonic distribution of CD.

Abstract
BACKGROUND Surgery is considered a cornerstone of inflammatory bowel disease (IBD) treatment. In the last years, robotic surgery has seen an increase in adoption rates for both benign and malignant diseases. OBJECTIVE This work aims to review the current applications of robotic surgery in IBD. DISCUSSION AND CONCLUSION Minimally-invasive techniques have been applied to the treatment of IBD for more than 20 years. Investments in surgical digital and robotic platforms are increasingly arising, with an estimate of getting doubled within the next 5 years. Robotic surgery represents the newest technology available to reduce the impact of surgery on patients affected by IBD, and may theoretically be even more effective than other minimally-invasive techniques given the lower rate of conversion to open surgery as compared to laparoscopy according to many large retrospective series. Data on robotic surgery applied to IBD are still scarce and initial experiences in high-volume centers from retrospective series suggested that robotic surgery may achieve similar results when compared to laparoscopy. A new wave of robotics incorporating artificial intelligence is awaited to empower the capability of IBD surgeon in terms of intraoperative decision-making beyond technical skill enhancement.

Reduced duration of stay after elective colorectal surgery during the peak phase of COVID-19 pandemic: A positive effect of infection risk awareness? Surgery 2020; 170:558-562. [PMID: 33714617 PMCID: PMC7757347 DOI: 10.1016/j.surg.2020.12.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Revised: 12/04/2020] [Accepted: 12/14/2020] [Indexed: 01/23/2023]
Abstract
Background While elective surgery was shut down in most settings during the 2019 novel coronavirus pandemic, some referral centers were designated as surgery hubs. We sought to investigate how the pandemic scenario impacted the quality of a long-established enhanced recovery protocol colorectal surgery program in 2 referral centers, designated as colorectal surgery hubs, located in the epicentral Italian regions hardest hit by the pandemic. Methods We compared short-term outcomes of patients undergoing major colorectal surgery with a long-established enhanced recovery protocol during the coronavirus disease 2019 outbreak occurred in 2020 (group A) with the correspondent timeframe of 2019 (group B). Primary outcomes were morbidity and mortality, duration of stay, and readmission rate. Results One hundred and thirty-six patients underwent major colorectal surgery in group A and 173 in group B. Postoperative complications and readmission rate were comparable between the 2 groups. Oncologic case-log was predominant in group A compared with group B (73.5 vs 61%; P = .01). A significantly shorter overall duration of stay was found in group A (P < .001). Uncomplicated patients of group A had a shorter duration of stay when compared with uncomplicated patients of group B (P = .008). Conclusion Under special precautionary measures, major colorectal surgery can be undertaken on elective basis even during coronavirus disease 2019 pandemic with reasonable results. A reduction of duration of stay within a long-established enhanced recovery protocol colorectal surgery program was observed during the coronavirus disease 2019 pandemic occurred in 2020 in comparison with the correspondent timeframe of the previous year without compromising short-term outcomes. The pandemic uncovered the positive impact of patients’ commitment to reducing duration of stay as the empowered risk awareness likely promoted their compliance to the enhanced recovery protocol.

Abstract
Background Sphingosine-1-phosphate receptor 2 (S1PR2) mediates pleiotropic functions encompassing cell proliferation, survival, and migration, which become collectively de-regulated in cancer. Information on whether S1PR2 participates in colorectal carcinogenesis/cancer is scanty, and we set out to fill the gap. Methods We screened expression changes of S1PR2 in human CRC and matched normal mucosa specimens [N = 76]. We compared CRC arising in inflammation-driven and genetically engineered models in wild-type (S1PR2+/+) and S1PR2 deficient (S1PR2−/−) mice. We reconstituted S1PR2 expression in RKO cells and assessed their growth in xenografts. Functionally, we mimicked the ablation of S1PR2 in normal mucosa by treating S1PR2+/+ organoids with JTE013 and characterized intestinal epithelial stem cells isolated from S1PR2−/−Lgr5-EGFP- mice. Results S1PR2 expression was lost in 33% of CRC; in 55%, it was significantly decreased, only 12% retaining expression comparable to normal mucosa. Both colitis-induced and genetic Apc+/min mouse models of CRC showed a higher incidence in size and number of carcinomas and/or high-grade adenomas, with increased cell proliferation in S1PR2−/− mice compared to S1PR2+/+ controls. Loss of S1PR2 impaired mucosal regeneration, ultimately promoting the expansion of intestinal stem cells. Whereas its overexpression attenuated cell cycle progression, it reduced the phosphorylation of AKT and augmented the levels of PTEN. Conclusions In normal colonic crypts, S1PR2 gains expression along with intestinal epithelial cells differentiation, but not in intestinal stem cells, and contrasts intestinal tumorigenesis by promoting epithelial differentiation, preventing the expansion of stem cells and braking their malignant transformation. Targeting of S1PR2 may be of therapeutic benefit for CRC expressing high Lgr5. Graphical Abstract. Schematic drawing of the role of S1PR2 in normal mucosa and colorectal cancer. In the normal mucosa, S1PR2 is highly expressed by differentiated cells at the upper region of both colon and intestinal crypts (S1PR2 ON), but not by the undifferentiated stem cell at the base of the crypts (S1PR2 OFF), in which acts as a negative proliferative regulator promoting epithelial differentiation. Its loss leads to the expansion of stem cells and reduced levels of PTEN and Axin-2, two negative regulators respectively of PI3K/AKT and Wnt signaling that control β-catenin signaling. The translocation of β-catenin into the nucleus promotes the transcription of target genes involved in the proliferation and malignant transformation. Thereby, S1PR2 works in the intestine as a tumor suppressor ![]()
