RESUMO
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: 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.

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.

INTRODUCTION: Single-incision laparoscopic surgery (SILS) aims to minimize the surgical access trauma by reducing the number of abdominal incisions to a single site, potentially offering better cosmetic results and decreased postoperative pain. In this study, we compare the results of SILS ileocolic resection for Crohn's disease (CD) to conventional laparoscopy and open surgery using a propensity score-matched analysis in a retrospective national multicentre study. METHODS: All consecutive patients undergoing elective SILS ileocaecal or redo ileocolic resection for primary and recurrent CD from 1 June 2018 to 31 May 2019 were included. Patients were matched 1:1:1 with laparoscopy and open surgery according to perianal disease, recurrent disease, penetrating phenotype of CD, history of previous abdominal surgery, preoperative medical treatment with steroids and anti-TNF. Postoperative morbidity within 30 days of surgery was the primary endpoint. RESULTS: Fifty-eight patients were included in each group, for a total of 174 patients. The conversion rate for SILS and laparoscopy was 10.3% and 12%, respectively, with no difference in the incidence of postoperative complications (13.8% and 12%, p = 0.77), whilst open surgery demonstrated a worse morbidity profile, with a complication rate of 25.9% (p < 0.0001). Median length of hospital stay following SILS ileocolic resection was 5 days, significantly shorter compared to 7 days for laparoscopy and 9 for open surgery (p < 0.0001). CONCLUSIONS: SILS ileocolonic resection for CD demonstrated a comparable morbidity profile compared to laparoscopy in selected patients, with a reduced length of postoperative hospital stay.

AIM: Graciloplasty (GP) is indicated in the case of recurrent rectovaginal fistula (RVF) after failure of previous local treatments. The aim of this study was to assess risk factors for GP failure performed for RVF. METHODS: This is a retrospective study based on a prospective database on GP, coming from two expert centres. RESULTS: Sixty-one patients undergoing a first GP for RVF (n = 51) or ileal-vaginal fistula after ileal pouch anal anastomosis (n = 10), with a mean age of 42 years (range 24-72), were analysed. After a mean follow-up of 56 ± 48 months (range 1-183), failure of GP (considered as persistent stoma and/or clinical RVF) was noted in 24/61 patients (39%). The failure rate was 43% (13/30) in the case of Crohn's disease, 38% (3/8) in the case of ileal-vaginal fistula after ileal pouch anal anastomosis for ulcerative colitis, 30% (3/10) in the case of obstetrical RVF, 33% (1/3) in the case of post radiotherapy RVF and 40% (4/10) for other causes (not significant). Two risk factors for failure of GP were found on univariate analysis: (1) absence of postoperative antibiotic prophylaxis-only 3/24 (13%) patients with failure of GP received postoperative antibiotic prophylaxis versus 18/37 (49%) patients with success of GP (P = 0.0053); (2) postoperative perineal infection-11/23 (48%) with failure of GP developed postoperative perineal infection versus only 4/37 (10%) patients with success of GP (P = 0.0021). CONCLUSIONS: Failure of GP for RVF is observed in approximately 40% of the patients whatever the aetiology of the fistula. A reduced failure rate was associated with systematic postoperative antibiotic prophylaxis.

INTRODUCTION: Granular cellular tumors are unusual lesions that can occur in the gastrointestinal tract, where they localize most commonly to the esophagus followed by the colon. AREAS COVERED: We report a case of a young man with a sub-epithelial lesion of the ascending colon, removed by endoscopic submucosal dissection. Histological examination revealed a granular cellular tumor without features of malignancy. We present a systematic review of the English literature evaluating granular cellular tumors of lower gastrointestinal tract. EXPERT COMMENTARY: These tumors are usually asymptomatic and discovered incidentally during endoscopy performed for other reasons. Though their histological behavior is usually benign, 1-2% are malignant. Therefore, it is important that these lesions are excised and adequately pathologically characterized.

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.

PURPOSE: An oncologically effective total mesorectal excision (TME) still represents a technical challenge, especially in the presence of a low rectal cancer and anatomical restraints such as obesity or narrow pelvis. Recently, few reports have shown that transanal TME was feasible and associated with good outcomes. Nevertheless, a widespread employment of the technique has yet to happen due to the doubts about the reproducibility of the results outside a tertiary specialized center. METHODS: Between February 2014 and June 2015, patients with low rectal cancer underwent a transanal TME with laparoscopic assistance. The end points included the oncologic adequacy of the mesorectal excision and the perioperative outcomes. RESULTS: Eleven patients (9 male, median age 70.5 years) with proven low rectal cancer were enrolled in the study. The median distance of the tumor from the anal verge was 5 cm (2-7). Four patients (36.4 %) received preoperative chemoradiation. The median operative time was 360 min (275-445). Postoperative morbidity (36.4 %) included one (9.1 %) anastomotic leak requiring a reoperation. The median length of hospital stay was 8 days (3-28). The median distance from the circumferential and distal resection margins were, respectively, 5 (1-20) and 10 (5-20) mm, and the mean number of harvested lymph nodes was 21.7 (11-50). All cases had a complete or nearly complete mesorectal plane of surgery. CONCLUSIONS: Although technically challenging, the initial results suggest that transanal TME could be a feasible, oncologically safe, and reproducible operation. However, more robust studies are required to assess the short- and long-term outcomes.

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.

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.

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.
RESUMO
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.

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.
RESUMO
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: National data indicate that patients with T4N0 colon carcinoma have worse oncologic outcomes than other stage II cases. Our hypothesis was that optimized surgical resection and lymph node staging in a specialized center could eliminate discrepancies in oncologic outcomes within stage II colon carcinomas. METHODS: Patient characteristics and outcomes after oncologically radical colectomy for pT4N0 were compared to control groups of T1-2N1, T3N1, and T3N0 cases. Group comparisons were adjusted for age, American Society of Anesthesiologists score, tumor location, year of surgery, and duration of follow-up. Cases with at least 12 collected lymph nodes and uninvolved resection margins (R0) were analyzed separately. In addition, the T4a subgroup was compared to both T4b cases with involvement of bowel loops and with infiltration of other organs or structures. RESULTS: T4N0 patients had worse oncologic outcomes than T1-2N1 patients and were comparable to T3N1 patients, regardless of margins status or lymph node collection. When a T4b tumor infiltrated bowel, survival and recurrence rates were similar to T4a cases, while T4b tumors involving other organs were associated with increased recurrence rate and reduced survival. CONCLUSIONS: T4N0 colon carcinoma remains associated with poor oncologic outcomes, regardless of treatment in a specialized center. The biologic aggressiveness of T4N0 colon cancers and the different oncologic outcomes according to specific organ infiltration should be taken into consideration in the choice of adjuvant therapies.
