BACKGROUND AND AIMS: The terminal ileum is the most frequent site of Crohn's Disease (CD) that necessitates surgery. Of the postoperative complications (POCs) associated with ileocaecal resection for CD, intra-abdominal septic complications (IASCs) include anastomotic leak, abscesses, and entero-cutaneous fistula. We aimed to identify predictors of IASCs and severe POCs (Clavien-Dindo ≥3) after primary ileocaecal resection for CD. METHODS: This is a retrospective single-centre cohort study including all consecutive primary ileocaecal resection for CD in a tertiary IBD centre between 2004 and 2021. RESULTS: A total of 853 patients underwent primary ileocaecal resection for CD. 307 (36.6 %) patients were receiving antibiotics, 253 (29.8 %), systemic steroids, and 178 (21.0 %) oral budesonide at surgery. At 90 days, 260 (30.8 %) patients developed POCs, 62 (7.3 %) severe POCs, and 56 (6.6 %) IASCs. At multivariate analysis, severe POCs were associated with lower preoperative albumin levels (OR1.58, 95 %CI 1.02-2.50, p = 0.040) and a history of cardiovascular diseases (OR2.36, 95 %CI 1.08-7.84, p = 0.030). IASCs were associated with lower preoperative albumin levels (OR1.81, 95 %CI 1.15-2.94, p = 0.011) and oral budesonide (OR2.07, 95 %CI 1.12-3.83, p = 0.021) with a dose-dependent effect. CONCLUSIONS: The independent association, dose-dependent effect, and biological plausibility of budesonide and IASCs suggest a robust causal effect. Oral budesonide should be carefully assessed before primary ileocaecal resection for CD.
RESUMEN
INTRODUCTION: The multiorgan procurement (MOP) represents a chance for the general surgery resident to learn the fundamental steps of open abdominal surgery. The objective of this study was to evaluate the impact of MOP on the residents' open surgical skills. METHODS: Residents' surgical skills were assessed during a 6-month transplant rotation (October 2020-March 2021) using a modified Objective Structured Assessment of Technical Skills with the global rating scale. The surgeries were self-assessed by residents and tutors based on 9 specific steps (SS) and 4 general skills (GS). Each item was rated from 1 (poor) to 5 (excellent) with a maximum score of 45 points for SS and 20 for GS. A crossed-effects linear regression analysis was performed both to evaluate any associations between GS/SS scores and some prespecified covariates, and to study differences in the assessments performed by residents and tutors. RESULTS: Residents actively participated in a total of 59 procurements. In general, there were no significant differences in SS/GS mean scorings between residents (n = 15) and tutors (n = 5). There was a significantly positive association between mean GS/SS scorings and the number of donor surgeries performed (at least 5). Comparing the evaluations of the tutors with the residents, this significance was retained only when scorings were assigned by the tutors. CONCLUSIONS: MOP was shown to improve basic open surgical skills among residents. Awareness of the utility of a clinical rotation in transplant surgery should be raised also on an institutional level.

BACKGROUND: The association between volume, complications and pathological outcomes is still under debate regarding colorectal cancer surgery. The aim of the study was to assess the association between centre volume and severe complications, mortality, less-than-radical oncologic surgery, and indications for neoadjuvant therapy. METHODS: Retrospective analysis of 16,883 colorectal cancer cases from 80 centres (2018-2021). Outcomes: 30-day mortality; Clavien-Dindo grade >2 complications; removal of ≥ 12 lymph nodes; non-radical resection; neoadjuvant therapy. Quartiles of hospital volumes were classified as LOW, MEDIUM, HIGH, and VERY HIGH. Independent predictors, both overall and for rectal cancer, were evaluated using logistic regression including age, gender, AJCC stage and cancer site. RESULTS: LOW-volume centres reported a higher rate of severe postoperative complications (OR 1.50, 95% c.i. 1.15-1.096, P = 0.003). The rate of ≥ 12 lymph nodes removed in LOW-volume (OR 0.68, 95% c.i. 0.56-0.85, P < 0.001) and MEDIUM-volume (OR 0.72, 95% c.i. 0.62-0.83, P < 0.001) centres was lower than in VERY HIGH-volume centres. Of the 4676 rectal cancer patients, the rate of ≥ 12 lymph nodes removed was lower in LOW-volume than in VERY HIGH-volume centres (OR 0.57, 95% c.i. 0.41-0.80, P = 0.001). A lower rate of neoadjuvant chemoradiation was associated with HIGH (OR 0.66, 95% c.i. 0.56-0.77, P < 0.001), MEDIUM (OR 0.75, 95% c.i. 0.60-0.92, P = 0.006), and LOW (OR 0.70, 95% c.i. 0.52-0.94, P = 0.019) volume centres (vs. VERY HIGH). CONCLUSION: Colorectal cancer surgery in low-volume centres is at higher risk of suboptimal management, poor postoperative outcomes, and less-than-adequate oncologic resections. Centralisation of rectal cancer cases should be taken into consideration to optimise the outcomes.

INTRODUCTION: As robotic surgery increases its reach, novel platforms are being released. We present the first 17 consecutive cases of alimentary tract surgery performed with the HugoTM RAS (Medtronic). METHODS: patients were selected to undergo surgery from February through April 2023. Exclusion criteria were age <16 years, BMI>60, ASA IV. RESULTS: 17 patients underwent ileocaecal resection for Chrons disease (2 M and 1 F) and pseudo-obstruction of the terminal ileum (1 M), cholecystectomy (3 M and 5 F), subtotal gastrectomy with D2 lymphadenectomy (1 F), sleeve gastrectomy (1 F), hiatal hernia repair with Nissen fundoplication (1 M), right hemicolectomy (1 M) and sigmoidectomy (1 M). No conversion to an open approach or any arm collisions requiring corrective actions were reported. CONCLUSIONS: Our preliminary experience with the HugoTM RAS point to safety and feasibility for a rather wide spectrum of surgical procedures of the alimentary tract.

Symptomatic Uncomplicated Diverticular Disease (SUDD) is a syndrome within the diverticular disease spectrum, characterized by local abdominal pain with bowel movement changes but without systemic inflammation. This narrative review reports current knowledge, delivers practical guidance, and reveals challenges for the clinical management of SUDD. A broad and common consensus on the definition of SUDD is still needed. However, it is mainly considered a chronic condition that impairs quality of life (QoL) and is characterized by persistent left lower quadrant abdominal pain with bowel movement changes (eg, diarrhea) and low-grade inflammation (eg, elevated calprotectin) but without systemic inflammation. Age, genetic predisposition, obesity, physical inactivity, low-fiber diet, and smoking are considered risk factors. The pathogenesis of SUDD is not entirely clarified. It seems to result from an interaction between fecal microbiota alterations, neuro-immune enteric interactions, and muscular system dysfunction associated with a low-grade and local inflammatory state. At diagnosis, it is essential to assess baseline clinical and Quality of Life (QoL) scores to evaluate treatment efficacy and, ideally, to enroll patients in cohort studies, clinical trials, or registries. SUDD treatments aim to improve symptoms and QoL, prevent recurrence, and avoid disease progression and complications. An overall healthy lifestyle - physical activity and a high-fiber diet, with a focus on whole grains, fruits, and vegetables - is encouraged. Probiotics could effectively reduce symptoms in patients with SUDD, but their utility is missing adequate evidence. Using Rifaximin plus fiber and Mesalazine offers potential in controlling symptoms in patients with SUDD and might prevent acute diverticulitis. Surgery could be considered in patients with medical treatment failure and persistently impaired QoL. Still, studies with well-defined diagnostic criteria for SUDD that evaluate the safety, QoL, effectiveness, and cost-effectiveness of these interventions using standard scores and comparable outcomes are needed.
RESUMEN
BACKGROUND: Anastomotic leak (AL) remains one of the most relevant complications after intestinal resection for Crohn's disease (CD). While surgery has always been considered the standard treatment for perianastomotic collection, percutaneous drainage (PD) has been proposed as a potential alternative. METHODS: Retrospective study in consecutive patients treated with either PD or surgery for AL after intestinal resection for CD between 2004 and 2022. AL was defined as a perianastomotic fluid collection confirmed by radiological findings. Patients with generalized peritonitis or clinical instability were excluded. PRIMARY AIM: To compare the success rate of PD vs. surgery. Secondary aims: To compare the outcomes at 90 days after the procedures; to identify the variables associated with the indication for PD. RESULTS: A total of 47 patients were included, of which 25 (53%) underwent PD and 22 (47%) surgery. The success rate was 84% in the PD and 95% in the surgery group (p = 0.20). There were no significant differences between the PD and surgery group in postoperative medical and surgical complications, discharge, readmission or reoperation rates at 90 days. PD was more likely to be performed in patients with later diagnosis of AL (OR 1.25, 95% CI 1.03-1.53, p = 0.027), undergoing ileo-colic anastomosis alone (OR 3.72, 95% CI 2.29-12.45, p = 0.034) and treated after 2016 (OR 6.36, 95% CI 1.04-39.03, p = 0.046). CONCLUSION: The present study suggests that PD is a safe and effective procedure to treat anastomotic leak and perianastomotic collection in CD patients. PD should be indicated in all eligible patients as an effective alternative to surgery.
RESUMEN
The pelvic anatomy poses great challenges to orthopedic surgeons. Sarcomas are often large in size and typically enclosed in the narrow confines of the pelvis with the close proximity of vital structures. The aim of this study is to report a systematic planned multidisciplinary surgical approach to treat pelvic sarcomas. Seventeen patients affected by bone and soft tissue sarcomas of the pelvis, treated using a planned multidisciplinary surgical approach, combining the expertise of orthopedic oncology and other surgeons (colleagues from urology, vascular surgery, abdominal surgery, gynecology and plastic surgery), were included. Seven patients were treated with hindquarter amputation; 10 patients underwent excision of the tumor. Reconstruction of bone defects was conducted in six patients with a custom-made 3D-printed pelvic prosthesis. Thirteen patients experienced at least one complication. Well-organized multidisciplinary collaborations between each subspecialty are the cornerstone for the management of patients affected by pelvic sarcomas, which should be conducted in specialized centers. A multidisciplinary surgical approach is of paramount importance in order to obtain the best successful surgical results and adequate margins for achieving acceptable outcomes.

BACKGROUND: Diabetes Mellitus (DM) may occur in IBD and influence the disease progression. AIM: To compare disease course and treatment outcomes in IBD patients with and without DM. METHODS: This is a systematic review with meta-analysis comparing patients with IBD plus DM with patients with IBD only. PRIMARY ENDPOINTS: need for surgery, IBD-related complications, hospitalizations, sepsis, mortality. Quality of life and costs were assessed. RESULTS: Five studies with 71,216 patients (49.1% with DM) were included. Risk for IBD-related complications (OR=1.12, I2 98% p = 0.77), mortality (OR=1.52, I2 98% p = 0.37) and IBD-related surgery (OR=1.20, I2 81% p = 0.26) did not differ. Risk of IBD-related hospitalizations (OR=2.52, I2 0% p < 0.00001) and sepsis (OR=1.56, I2 88% p = 0.0003) was higher in the IBD+DM group. Risk of pneumonia and urinary tract infections was higher in the IBD+DM group (OR=1.72 and OR=1.93), while risk of C. Difficile infection did not differ (OR=1.22 I2 88% p = 0.37). Mean Short Inflammatory Bowel Disease Questionnaire score was lower in the IBD+DM group (38.9 vs. 47, p = 0.03). Mean health care costs per year were $10,598.2 vs $3747.3 (p < 0.001). CONCLUSION: DM might negatively affect the course of IBD by increasing the risk of hospitalization and infections, but not IBD-related complications and mortality.

Importance: Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. Objective: To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. Design, Setting, and Participants: This retrospective, multicenter cohort study included all 17â¯938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. Exposures: Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. Main Outcomes and Measures: The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. Results: A total of 17â¯938 patients (10â¯007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10â¯142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95% CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95% CI, 1.15-1.53; P < .001), and stenotic lesions (OR, 1.15; 95% CI, 1.01-1.31; P = .03). Conclusions and Relevance: This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients.

Surgery for ileocolonic Crohn's disease can result in temporary or permanent stoma formation which can be associated with morbidity as parastomal and incisional hernias, readmissions due to obstruction or high stoma output, and have a negative impact on quality of life. We propose an international retrospective trainee-led study of the outcomes of temporary stomas in patients with Crohn's disease. We aim to evaluate both the short-term (6 month) and mid-term (18 month) outcomes of temporary stomas in patients with Crohn's Disease. Retrospective, multicentre, observational study including all patients who underwent elective or emergency surgery for ileal, colonic and ileocolonic Crohn's disease during a 4-year study period. Primary outcome is the proportion of patients who still have an ileostomy or colostomy 18 months after the initial surgery. Secondary outcomes: complications related to stoma formation and stoma reversal surgery; time interval between stoma formation and stoma reversal; risk factors for stoma formation and non-reversal of the stoma. We present the study protocol for a trainee-led, multicentre, observational study. Previous research has demonstrated significant heterogeneity surrounding the formation and the timing of reversal surgery in patients having a temporary ileostomy following colorectal cancer surgery, highlighting the need to address these same questions in Crohn's disease, which is the aim of our research.

BACKGROUND: The extent of resection in colonic Crohn's disease [cCD] is still a topic of debate, depending on the number of locations, the risk of recurrence and permanent stoma, and the role of medical therapy. METHODS: The Segmental COlecTomy for CroHn's disease [SCOTCH] international study is a retrospective analysis on six tertiary centre prospective databases, comprising all consecutive, unselected patients operated on between 2000 and 2019 with segmental colectomy [SC] or total colectomy [TC] for cCD. The primary aim was long-term surgical recurrence. Secondary aims were perioperative complications, stoma formation and predictors of recurrence. RESULTS: Among 687 patients, SC was performed in 285 [41.5%] and TC in 402 [58.5%]. Mean age at diagnosis and surgery, disease duration, and follow-up were 30â ±â 15.8, 40.4â ±â 15.4, 10.4â ±â 8.6 and 7.1â ±â 5.2 years respectively. Isolated cCD, inflammatory pattern, perianal CD, younger age, longer disease duration and preoperative maximal therapy were more frequent in TC, while SC presented more small bowel locations and perforating disease, required fewer 90-day re-admissions, and fewer temporary and definitive stomas. Morbidity and mortality were similar. The 15-year surgical recurrence was 44% in TC and 27% in SC [pâ =â 0.006]. In patients with one to three diseased segments, recurrence risk was related to the omission of biological therapy (hazard ratio [HR] 5.6), the number of segments [HR 2.5], perianal disease [HR 1.9] and paediatric diagnosis [HR 2.8]. CONCLUSION: When technically feasible, SC is safe and reduces temporary and permanent stoma. Young age, number of locations and perianal disease adversely affect, but postoperative biological therapy significantly reduces, the long-term surgical recurrence.

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.

BACKGROUND: Laparoscopic ileal pouch-anal anastomosis (IPAA) technique is not standardized. An irregular division of the rectum could result in poor functional outcomes and residual diseased mucosa. The aim of the study was to develop a new technique for performing the rectal transection via a laparoscopic approach, and to compare the outcomes of this technique with those of the open surgery IPAA. METHODS: This prospective study included all patients who underwent restorative proctectomy (following a previous subtotal colectomy) for ulcerative colitis in October 2017-November 2020. Rectal division was performed using a 30 mm open linear stapler which was applied laparoscopically across the distal rectum. Postoperative and functional outcomes, length of anal stump and completeness of mucosal removal were compared. Only the patients who had their ileostomy reversed by 31 December 2020 and, therefore, a minimum follow-up of 6 months from the ileostomy closure, were included in the analysis of the functional outcomes and quality of life. RESULTS: There were 207 patients (161 laparoscopic, 46 open). Median age was 43 (18-77) years and 85 patients (41.1%) were male. Major complications (9.3 vs. 8.7%, p = 0.89) including anastomotic leaks (3.7 vs 4.4%, p = 0.84) were similar after laparoscopic and open IPAA. Patients reported a comparable number of bowel movements during the day (6 vs. 7, p = 0.21) and at night (2 vs. 2, p = 0.66), and a similar rate of episodes of incontinence during the previous 6 months (3.7 vs. 4.3%, p = 0.75). The mean Cleveland Global Quality of Life score was also similar (0.79 vs. 0.74, p = 0.35). CONCLUSION: Our technique is safe and reproducible, and replicates the results of the open IPAA, while maintaining the advantages of minimally invasive surgery and avoiding any kind of anal manipulation which could result in poor long-term functional outcomes.

BACKGROUND: This study compared patients undergoing colorectal cancer surgery in 20 hospitals of northern Italy in 2019 versus 2020, in order to evaluate whether COVID-19-related delays of colorectal cancer screening resulted in more advanced cancers at diagnosis and worse clinical outcomes. METHOD: This was a retrospective multicentre cohort analysis of patients undergoing colorectal cancer surgery in March to December 2019 versus March to December 2020. Independent predictors of disease stage (oncological stage, associated symptoms, clinical T4 stage, metastasis) and outcome (surgical complications, palliative surgery, 30-day death) were evaluated using logistic regression. RESULTS: The sample consisted of 1755 patients operated in 2019, and 1481 in 2020 (both mean age 69.6 years). The proportion of cancers with symptoms, clinical T4 stage, liver and lung metastases in 2019 and 2020 were respectively: 80.8 versus 84.5 per cent; 6.2 versus 8.7 per cent; 10.2 versus 10.3 per cent; and 3.0 versus 4.4 per cent. The proportions of surgical complications, palliative surgery and death in 2019 and 2020 were, respectively: 34.4 versus 31.9 per cent; 5.0 versus 7.5 per cent; and 1.7 versus 2.4 per cent. Cancers in 2020 (versus 2019) were more likely to be symptomatic (odds ratio 1.36 (95 per cent c.i. 1.09 to 1.69)), clinical T4 stage (odds ratio 1.38 (95 per cent c.i. 1.03 to 1.85)) and have multiple liver metastases (odds ratio 2.21 (95 per cent c.i. 1.24 to 3.94)), but were not more likely to be associated with surgical complications (odds ratio 0.79 (95 per cent c.i. 0.68 to 0.93)). CONCLUSION: Colorectal cancer patients who had surgery between March and December 2020 had an increased risk of advanced disease in terms of associated symptoms, cancer location, clinical T4 stage and number of liver metastases.

Background: Hyperglycemia and obesity are associated with a worse prognosis in subjects with COVID-19 independently. Their interaction as well as the potential modulating effects of additional confounding factors is poorly known. Therefore, we aimed to identify and evaluate confounding factors affecting the prognostic value of obesity and hyperglycemia in relation to mortality and admission to the intensive care unit (ICU) due to COVID-19. Methods: Consecutive patients admitted in two Hospitals from Italy (Bologna and Rome) and three from Spain (Barcelona and Girona) as well as subjects from Primary Health Care centers. Mortality from COVID-19 and risk for ICU admission were evaluated using logistic regression analyses and machine learning (ML) algorithms. Results: As expected, among 3,065 consecutive patients, both obesity and hyperglycemia were independent predictors of ICU admission. A ML variable selection strategy confirmed these results and identified hyperglycemia, blood hemoglobin and serum bilirubin associated with increased mortality risk. In subjects with blood hemoglobin levels above the median, hyperglycemic and morbidly obese subjects had increased mortality risk than normoglycemic individuals or non-obese subjects. However, no differences were observed among individuals with hemoglobin levels below the median. This was particularly evident in men: those with severe hyperglycemia and hemoglobin concentrations above the median had 30 times increased mortality risk compared with men without hyperglycemia. Importantly, the protective effect of female sex was lost in subjects with increased hemoglobin levels. Conclusions: Blood hemoglobin substantially modulates the influence of hyperglycemia on increased mortality risk in patients with COVID-19. Monitoring hemoglobin concentrations seem of utmost importance in the clinical settings to help clinicians in the identification of patients at increased death risk.

BACKGROUND: The aim of the study was to evaluate perioperative outcomes and to evaluate factors influencing rative morbidity and adoption of minimally invasive technique in 1-team (1-T) versus two teams (2-T) management of synchronous colorectal liver metastases. METHODS: Within four referral centers, a group of 234 patients treated in 1-T centers was identified and compared with a group of 253 patients treated in 2-T. A nonparametric bootstrap process was applied to the original cohorts of 1-T group and 2-T group as a resampling method to obtain bootstrapped cohorts (155 patients per group). RESULTS: 33.5% of patients in 1-T boot group and 38.1% in the 2-T boot group were operated by laparoscopic approach. Multivariate analysis revealed that approach to primary tumor (laparoscopic or open) and intraoperative blood loss were independent prognostic factors for morbidity. Team approach did not show any significant correlation with incidence of postoperative complications nor with choice for laparoscopic approach. CONCLUSION: The optimization of team strategy for patients with SCRLM is not solely based on the adoption of a 1-T or 2-T approach, but should instead be based on the implementation of a standard protocol for management of these patients.
