RESUMEN
BACKGROUND: Prophylactic surgery for familial adenomatous polyposis has evolved over several decades. Restorative proctocolectomy with IPAA provides an alternative to total abdominal colectomy with ileorectal anastomosis. We have previously shown that the rate of proctectomy and rectal cancer after total abdominal colectomy with ileorectal anastomosis in the "pre-pouch era" was 32% and 13%, respectively. OBJECTIVE: To determine the rate of proctectomy and rectal cancer among familial adenomatous polyposis patients and relative rectal sparing (fewer than 20 rectal polyps) selected for total abdominal colectomy with ileorectal anastomosis in the modern era. DESIGN: Retrospective cohort study. SETTING: Single tertiary care institution with a hereditary colorectal cancer registry. PATIENTS: Patients with familial adenomatous polyposis who underwent total abdominal colectomy with ileorectal anastomosis between 1993 and 2020. MAIN OUTCOME MEASURES: Incidence of proctectomy for any indication and rectal cancer. RESULTS: A total of 197 patients with a median age of 24 years (range, 10-67) were included. The median follow-up after total abdominal colectomy with ileorectal anastomosis was 13 years (interquartile range, 6-17). Sixteen patients (8%) underwent proctectomy. Indications included rectal cancer in 6 patients (3%; 2 stage I and 4 stage III), polyps with high-grade dysplasia in 4 (2%), progressive polyp burden in 3 (1.5%), defecatory dysfunction in 2 (1%), and anastomotic leak in 1 (0.5%). Among 30 patients (18%) with 20 or more rectal polyps at the time of total abdominal colectomy with ileorectal anastomosis, 8 patients (26%) underwent proctectomy and 3 patients developed rectal cancer (10%). Among 134 patients (82%) with fewer than 20 polyps, 8 patients (6%) underwent proctectomy and 3 patients developed rectal cancer (2%). Number of rectal polyps at the time of total abdominal colectomy with ileorectal anastomosis was associated with the likelihood of proctectomy (OR 1.1, p < 0.001) but not incident rectal cancer ( p = 0.3). LIMITATION: Retrospective data collection. CONCLUSIONS: Patients with familial adenomatous polyposis selected for total abdominal colectomy with ileorectal anastomosis by rectal polyp number have low rates of proctectomy and rectal cancer compared to historical controls. With appropriate selection criteria and surveillance, total abdominal colectomy with ileorectal anastomosis remains an important and safe treatment option for patients with familial adenomatous polyposis.

RIESGO DE PROCTECTOMA DESPUS DE ANASTOMOSIS ILEORRECTAL EN POLIPOSIS ADENOMATOSA FAMILIAR EN LA ERA MODERNA: ANTECEDENTES:La cirugía profiláctica para la poliposis adenomatosa familiar (PAF) ha evolucionado durante varias décadas. La proctocolectomía restauradora con anastomosis anal con bolsa ileal (IPAA) proporciona una alternativa a la colectomía abdominal total con anastomosis ileorrectal (TAC/IRA). Anteriormente hemos demostrado que la tasa de proctectomía y cáncer de recto después de TAC/IRA en la era "pre-bolsa" era del 32% y el 13%, respectivamente.OBJETIVO:Determinar la tasa de proctectomía y cáncer de recto entre pacientes con PAF y pacientes con preservación rectal relativa (<20 pólipos rectales) seleccionados para TAC/IRA en la era moderna.DISEÑO:Estudio de cohorte retrospectivo.ÁMBITO:Institución única de atención terciaria con un registro de cáncer colorrectal hereditario.PACIENTES:Pacientes con PAF que se sometieron a TAC/IRA entre 1993 y 2020.MEDIDAS DE RESULTADO PRINCIPALES:Incidencia de proctectomía por cualquier indicación y cáncer de recto.RESULTADOS:Se incluyeron 197 pacientes con una mediana de edad de 24 años (rango 10-67). La mediana de seguimiento tras TAC/IRA fue de 13 años (RIC 6-17). 16 pacientes (8%) fueron sometidos a proctectomía. Las indicaciones incluyeron cáncer de recto en 6 (3%) (2 en estadio I y 4 en estadio III); pólipos con displasia de alto grado en 4 (2%); carga progresiva de pólipos en 3 (1,5%), disfunción defecatoria en 2 (1%); y fuga anastomótica en 1 (0,5%). Entre 30 pacientes (18%) con ≥20 pólipos rectales en el momento de TAC/IRA, 8 pacientes (26%) se sometieron a proctectomía y 3 pacientes desarrollaron cáncer de recto (10%). Entre 134 pacientes (82%) con <20 pólipos, 8 pacientes (6%) se sometieron a proctectomía y 3 pacientes desarrollaron cáncer de recto (2%). El número de pólipos rectales en el momento de TAC/IRA se asoció con la probabilidad de proctectomía (OR 1,1, p <0,001), pero no con la incidencia de cáncer de recto (p = 0,3).LIMITACIÓN:Recopilación de datos retrospectivos.CONCLUSIÓN:Los pacientes con PAF seleccionados para TAC/IRA por el número de pólipos rectales tienen tasas bajas de proctectomía y cáncer de recto en comparación con los controles históricos. Con criterios de selección y vigilancia adecuados, TAC/IRA sigue siendo una opción de tratamiento importante y segura para los pacientes con PAF. (Pre-proofed version ).

BACKGROUND: Advanced endoscopic resection techniques are used to treat colorectal neoplasms that are not amenable to conventional colonoscopic resection. Literature regarding the predictors of the outcomes of advanced endoscopic resections, especially from a colorectal surgical unit, is limited. OBJECTIVE: To determine the predictors of short-term and long-term outcomes after advanced endoscopic resections. DESIGN: Retrospective case series. SETTINGS: Tertiary care center. PATIENTS: Patients who underwent advanced endoscopic resections for colorectal neoplasms from November 2011 to August 2022. INTERVENTIONS: Endoscopic mucosal resection, endoscopic submucosal dissection, hybrid endoscopic submucosal dissection, and combined endoscopic laparoscopic surgery. MAIN OUTCOME MEASURES: Predictors of en bloc and R0 resection, bleeding, and perforation were determined using univariable and multivariable logistic regression models. Cox regression models were used to determine the predictors of tumor recurrence. RESULTS: A total of 1213 colorectal lesions from 1047 patients were resected (median age 66 [interquartile range, 58-72] years, 484 women [46.2%], median BMI 28.6 [interquartile range, 24.8-32.6]). Most neoplasms were in the proximal colon (898; 74%). The median lesion size was 30 (interquartile range, 20-40; range, 0-120) mm. Nine hundred eleven lesions (75.1%) underwent previous interventions. The most common Paris and Kudo classifications were 0 to IIa flat elevation (444; 36.6%) and IIIs (301; 24.8%), respectively. En bloc and R0 resection rates were 56.6% and 54.3%, respectively. Smaller lesions, rectal location, and procedure type (endoscopic submucosal dissection) were associated with significantly higher en bloc and R0 resection rates. Bleeding and perforation rates were 5% and 6.6%, respectively. Increased age was a predictor for bleeding (OR 1.06; 95% CI, 1.03-1.09; p < 0.0001). Lesion size was a predictor for perforation (OR 1.02; 95% CI, 1.00-1.03; p = 0.03). The tumor recurrence rate was 6.6%. En bloc (HR 1.41; 95% CI, 1.05-1.93; p = 0.02) and R0 resection (HR 1.49; 95% CI, 1.11-2.06; p = 0.008) were associated with decreased recurrence risk. LIMITATIONS: Single-center, retrospective study. CONCLUSIONS: Outcomes of advanced endoscopic resections can be predicted by patient-related and lesion-related characteristics. See Video Abstract . PREDICTORES DE LA RESECCION R, EN BLOQUE Y LAS COMPLICACIONES POR RESECCIONES ENDOSCPICAS AVANZADAS EN CASOS DE NEOPLASIA COLORRECTAL RESULTADOS DE PROCEDIMIENTOS: ANTECEDENTES:Las técnicas avanzadas de resección endoscópica se utilizan para el tratamiento de neoplasias colorrectales que no son susceptibles de resección colonoscópica convencional. La literatura sobre los predictores de los resultados de las resecciones endoscópicas avanzadas, especialmente en una unidad de cirugía colorrectal, es limitada.OBJETIVO:Determinar los predictores de resultados a corto y largo plazo después de resecciones endoscópicas avanzadas.DISEÑO:Serie de casos retrospectivos.LUGAR:Centro de tercer nivel de atención.PACIENTES:Pacientes sometidos a resecciones endoscópicas avanzadas por neoplasias colorrectales desde noviembre de 2011 hasta agosto de 2022.INTERVENCIÓNES:Resección endoscópica de la mucosa, disección endoscópica submucosa (ESD), ESD híbrida, cirugía laparoscópica endoscópica combinada.PRINCIPALES MEDIDAS DE RESULTADO:Los predictores de resección en bloque y R0, sangrado y perforación se determinaron mediante modelos de regresión logística univariables y multivariables. Se utilizaron modelos de regresión de Cox para determinar los predictores de recurrencia del tumor.RESULTADOS:Se resecaron 1.213 lesiones colorrectales en 1.047 pacientes [edad media 66 (58-72) años, 484 (46,2%) mujeres, índice de masa corporal medio 28,6 (24,8-32,6) kg/m 2 ]. La mayoría de las neoplasias se encontraban en el colon proximal (898, 74%). El tamaño medio de la lesión fue de 30mm (RIC: 20-40, rango: 0-120). 911 (75,1%) lesiones tenían intervenciones previas. Las clasificaciones de París y Kudo más comunes fueron 0-IIa elevación plana (444, 36,6%) y III (301, 24,8%), respectivamente. Las tasas de resección en bloque y R0 fueron del 56,6% y 54,3%, respectivamente. Las lesiones más pequeñas, la ubicación rectal y el tipo de procedimiento (ESD) se asociaron con tasas de resección en bloque y R0 significativamente más altas. Las tasas de sangrado y perforación fueron del 5% y 6,6%, respectivamente. La edad avanzada [1,06 (1,03-1,09), p < 0,0001] fue un predictor de sangrado. El tamaño de la lesión [1,02 (1,00-1,03), p = 0,03] fue un predictor de perforación. La tasa de recurrencia del tumor fue del 6,6%. En bloque [HR 1,41 (IC 95% 1,05-1,93), p = 0,02] y la resección R0 [HR 1,49 (IC 95% 1,11-2,06), p = 0,008] se asociaron con un menor riesgo de recurrencia.LIMITACIONES:Estudio unicéntrico, retrospectivo.CONCLUSIONES:Los resultados de las resecciones endoscópicas avanzadas pueden predecirse según las características del paciente y de la lesión.

BACKGROUND: Colorectal cancer (CRC) is rising in young adults between ages 20 to 49 years. CRC screening is endorsed for average-risk individuals beginning at ages 45 to 49 years. Targeting screening for individuals <45 years may be warranted if risk factors for advanced neoplasia can be identified. AIM: To identify factors associated with advanced colorectal neoplasia in adults aged <45 years. METHOD: Individuals ages 18 to 44 years who underwent colonoscopy at Cleveland Clinic between 2011 and 2021 with ≥1 advanced neoplasm (AN) were included. Patients with inflammatory bowel disease or inherited CRC syndromes were excluded. Demographics, comorbidities, family history of CRC, and colonoscopy indication were obtained. Patients with a normal colonoscopy constituted the control group. A multivariable logistic regression model was used to investigate the relationship between clinical variables and the presence of advanced colorectal neoplasia. RESULTS: In all, 13,006 patients were included, of which 651 (5%) patients had AN: 404 (62%) with tubular adenoma ≥10 mm, 29 (4.5%) tubular adenoma with high-grade dysplasia, 210 (32%) tubulovillous adenomas, 27 (4%) traditional serrated adenomas, 82 (13%) sessile serrated lesions ≥10 mm, 7(2%) sessile serrated lesions with dysplasia, and 29 (4.4%) patients had a CRC. Factors associated with AN were older age (means 38.5 vs. 36.6 y), history of smoking, diabetes, non-White race, higher body mass index (29.9 vs. 28.5 kg/m2), and lower vitamin D (27.6 vs. 32.2 ng/dl), all P<0.001. In the reduced multivariable model, factors associated with AN included tobacco use (OR 2.026 (current vs. never, P<0.0001), age (OR increase by 1.06 per year, P<0.0001), male gender (OR 1.476, P<0.0001), family history of CRC (OR 3.91, P<0.0001), aspirin use (1.31, P=0.035), and diabetes (OR 2.106, P 0.001). CONCLUSION: Increasing age, male gender, exposure to tobacco, family history of CRC, diabetes, and aspirin use were independently associated with advanced neoplasia in adults younger than 45. Targeted early screening to young adults with these risk factors may be justified. Large collaborative prospective studies are needed to validate our findings.
RESUMEN
AIM: Ileorectal anastomosis (IRA) following total abdominal colectomy (TAC) allows for resortation of bowel continuity but prior studies have reported rates of anastomotic leak (AL) to be as high as 23%. We aimed to report rates of AL and complications in a large cohort of patients undergoing IRA. We hypothesized that AL rates were lower than previously reported and that selective use of diverting loop ileostomy (DLI) is associated with decreased AL rates. METHOD: Patients undergoing TAC or end-ileostomy reversal with IRA, with or without DLI, between 1980 and 2021 were identified from a prospectively maintained institutional database and retrospectively analysed. Redo IRA cases were excluded. Short-term (30-day) surgical outcomes were collected using our database. AL was defined using a combination of imaging and, in the case of return to the operating room, intraoperative findings. RESULTS: Of 823 patients in the study cohort, DLI was performed in 27% and performed more frequently for constipation and inflammatory bowel disease. The overall AL rate was 3% (1% and 4% in those with and without DLI, respectively) and diversion was found to be protective against leak (OR 0.28, 95% CI 0.08-0.94, p = 0.04). However, patients undergoing diversion had a higher overall rate of postoperative complications (51% vs. 36%, p < 0.001) including superficial wound infection, urinary tract infection, dehydration, blood transfusion and portomesenteric venous thrombosis (all p < 0.04). CONCLUSION: Our study represents the largest series of patients undergoing IRA reported to date and demonstrates an AL rate of 3%. While IRA appears to be a viable surgical option for diverse indications, our study underscores the importance of careful patient selection and thoughtful consideration of staging the anastomosis and temporary faecal diversion when necessary.

AIM: Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the treatment of choice for colorectal cancer (CRC) in inflammatory bowel disease. CRC may also be discovered incidentally at IPAA for other indications. We sought to determine whether incidentally found CRC at IPAA was associated with worse outcomes. METHODS: Our institutional pouch registry (1983-2021) was retrospectively reviewed. Patients with CRC at pathology after IPAA were divided into two groups: a preoperative diagnosis (PreD) group and an incidental diagnosis (InD) group. Their long-term outcomes (overall survival, disease-free survival and pouch survival) were compared. RESULTS: We included 164 patients: 53 (32%) InD and 111 (68%) PreD. There were no differences in cancer staging, differentiation and location. After a median follow-up of 11 (IQR 3-25) years for InD and 9 (IQR 3-20) years for the PreD group, deaths were 14 (26%) in the InD group and 18 (16%) in the PreD group. Pouch failures were five (9%) in the InD group and nine (8%) in the PreD group, of which two (5%) and four (4%) were cancer related. Ten-year overall survival was 94% for InD and 89% for PreD (P = 0.41), disease-free survival was 95% for InD and 90% for PreD (P = 0.685) and pouch survival was 89% for InD and 97% for PreD (P = 0.80). Pouch survival at 10 years was lower in rectal versus colon cancer (87% vs. 97%, P = 0.01). No difference was found in outcomes in handsewn versus stapled anastomoses. CONCLUSION: Inflammatory bowel disease patients with incidentally found CRC during IPAA appear to have similarly excellent oncological and pouch outcomes to patients with a preoperative cancer diagnosis.

AIM: Restorative proctocolectomy with transabdominal ileal pouch-anal anastomosis (abd-IPAA) has become the standard surgical treatment for medically refractory ulcerative colitis (UC). However, it requires a technically difficult distal anorectal dissection and anastomosis due to the bony confines of the deep pelvis. To address these challenges, the transanal IPAA approach (ta-IPAA) was developed. This novel approach may offer increased visibility and range of motion compared with abd-IPAA, although its postoperative benefits remain unclear. The aim of this work was to perform a systematic review and meta-analysis to compare and inform the frequency of postoperative outcomes between ta-IPAA and abd-IPAA for patients with UC. METHOD: Several databases were searched from inception until May 2022 for studies reporting postoperative outcomes of patients undergoing ta-IPAA. Reviewers, working independently and in duplicate, evaluated studies for inclusion and graded the risk of bias. Odds ratios (OR), mean differences (MD) and prevalence ratio (PR) and their corresponding 95% confidence intervals (CIs) were calculated using random-effects models. Sensitivity analysis was performed. RESULTS: Ten retrospective studies comprising 284 patients with ta-IPAA were included. Total mesorectal excision was performed in 61.8% of cases and close rectal dissection in 27.9%. There was no difference in the odds of Clavien-Dindo (CD) I-II complications, CD III-IV and anastomotic leak (OR 0.96, 95% CI 0.27-3.40; OR 1.18, 95% CI 0.65-2.16; OR 1.37, 95% CI 0.58-3.23; respectively) between ta-IPAA and abd-IPAA. The ta-IPAA pooled CD I-II complication rate was 18% (95% CI 5%-35%) and for CD III-IV 10% (95% CI 5%-17%), and the anastomotic leak rate was 6% (95% CI 2%-10%). There were no deaths reported. CONCLUSIONS: This meta-analysis compared the novel ta-IPAA procedure with abd-IPAA and found no difference in postoperative outcomes. While the need for randomized controlled trails and comparison of functional outcomes between both approaches remains, this evidence should assist colorectal surgeons to decide if ta-IPAA is a viable alternative.

BACKGROUND: Appendiceal orifice lesions are often managed operatively with limited or oncologic resections. The aim is to report the management of appendiceal orifice mucosal neoplasms using advanced endoscopic interventions. METHODS: Patients with appendiceal orifice mucosal neoplasms who underwent advanced endoscopic resections between 2011 and 2021 with either endoscopic mucosal resection (EMR), endoscopic mucosal dissection (ESD), hybrid ESD, or combined endoscopic laparoscopic surgery (CELS) were included from a prospectively collected dataset. Patient and lesion details and procedure outcomes are reported. RESULTS: Out of 1005 lesions resected with advanced endoscopic techniques, 41 patients (4%) underwent appendiceal orifice mucosal neoplasm resection, including 39% by hybrid ESD, 34% by ESD, 15% by EMR, and 12% by CELS. The median age was 65, and 54% were male. The median lesion size was 20 mm. The dissection was completed piecemeal in 49% of patients. Post-procedure, one patient had a complication within 30 days and was admitted with post-polypectomy abdominal pain treated with observation for 2 days with no intervention. Pathology revealed 49% sessile-serrated lesions, 24% tubular adenomas, and 15% tubulovillous adenomas. Patients were followed up for a median of 8 (0-48) months. One patient with a sessile-serrated lesion experienced a recurrence after EMR which was re-resected with EMR. CONCLUSION: Advanced endoscopic interventions for appendiceal orifice mucosal neoplasms can be performed with a low rate of complications and early recurrence. While conventionally lesions at the appendiceal orifice are often treated with surgical resection, advanced endoscopic interventions are an alternative approach with promising results which allow for cecal preservation.

PURPOSE: Limited data exist regarding the surgical outcomes of acute colonic pseudo-obstruction (ACPO), commonly referred to as Ogilvie syndrome, in modern clinical practice. The prevailing belief is that surgery should be avoided due to previously reported high mortality rates. We aimed to describe the surgical results of ACPO treated within our institution. METHODS: Our prospectively maintained colorectal surgery registry was queried for patients diagnosed with ACPO, who underwent surgery between 2009 and 2022. Postoperative complications were graded according to Clavien-Dindo (CD) classification. The primary outcome was postoperative mortality. RESULTS: A total of 32 patients who underwent surgery for ACPO were identified. Overall, nonoperative therapy was initially administered to 21 patients (65.6%). The surgeries performed included total abdominal colectomy (15, 43.1%), ascending colectomy with end ileostomy (8, 25%), transverse colostomy (5, 15.6%), ileostomy and transverse colostomy (3, 9.4%), and Hartmann's operation (1, 3.1%). Severe postoperative complications (CD grade 3 or 4) occurred in five patients (15.6%). No recurrence of ACPO was observed and no patient required reoperation. The average postoperative length of stay was 14.5 days, 30-day mortality was 6.3% (n = 2), and 90-day mortality was 15.6% (n = 5) due to complications of underlying comorbidities. CONCLUSIONS: Surgical treatment was effective for patients with ACPO refractory to medical therapy or presenting with acute complications. Although postoperative complications were frequent, both the 30- and 90-day mortality rates were lower than previously documented in the literature. Further investigations are warranted to determine the optimal surgical strategy, which may involve total or segmental colectomy, or diversion alone without resection.

ABTRACT: BACKGROUND: When constructing an ileal pouch-anal anastomosis (IPAA), the rectal cuff should ideally be 1-2 cm long to avoid subsequent complications. METHODS: We identified patients from our IBD center who underwent redo IPAA for a long rectal cuff. Long rectal cuff syndrome (LRCS) was defined as a symptomatic rectal cuff ≥ 4 cm. RESULTS: Forty patients met the inclusion criteria: 42.5% female, median age at redo surgery 42.5 years. The presentation was ulcerative proctitis in 77.5% of the cases and outlet obstruction in 22.5%. The index pouch was laparoscopically performed in 18 patients (45%). The median rectal cuff length was 6 cm. The pouch was repaired in 16 (40%) cases, whereas 24 (60%) required the creation of a neo-pouch. At the final pathology, the rectal cuff showed chronic active colitis in 38 (90%) cases. After a median follow-up of 34.5 (IQR 12-109) months, pouch failure occurred in 9 (22.5%) cases. The pouch survival rate was 78% at 3 years. Data on the quality of life were available for 11 (27.5%) patients at a median of 75 months after redo surgery. The median QoL score (0-1) was 0.7 (0.4-0.9). CONCLUSION: LRCS, a potentially avoidable complication, presents uniformly with symptoms of ulcerative proctitis or stricture. Redo IPAA was restorative for the majority.

Microsatellite instability is rare in rectal cancer and associated with younger age of onset and Lynch syndrome. All rectal cancers should be tested for microsatellite instability prior to treatment decisions. Patients with microsatellite instability are relatively resistant to chemotherapy. However, recent small studies have shown dramatic response with neoadjuvant immunotherapy. Patients with Lynch syndrome have a hereditary predisposition to cancer and thus an elevated risk of metachronous cancer. Therefore, while "watch and wait" is a well-established practice for sporadic rectal cancers that obtain a complete clinical response after chemoradiation, its safety in patients with Lynch syndrome has not yet been defined. The extent of surgery for patients with Lynch syndrome and rectal cancer is controversial and there is significant debate as to the relative advantages of a segmental proctectomy with postoperative endoscopic surveillance versus a therapeutic and prophylactic total proctocolectomy. Surgical decision making for the patient with Lynch syndrome and rectal cancer is complex and demands a multidisciplinary approach, taking into account both patient- and tumor-specific factors. Neoadjuvant immunotherapy show great promise in the treatment of these patients, and further maturation of data from prospective trials will likely change the current treatment paradigm. Patients with Lynch syndrome and rectal cancer who do not undergo total proctocolectomy require yearly surveillance colonoscopies and should consider chemoprophylaxis with aspirin.
RESUMEN
Desmoid disease, though technically a benign condition, is nevertheless a leading cause of morbidity and mortality in patients with familial adenomatous polyposis (FAP). Desmoid disease impacts approximately 30% of FAP patients, with several known risk factors. It runs the gamut in terms of severity-ranging from small, slow-growing asymptomatic lesions to large, focally destructive, life-threatening masses. Desmoids usually occur following surgery, and several patient risk factors have been established, including female sex, family history of desmoid disease, 3' APC mutation, and extraintestinal manifestations of FAP. Desmoid disease-directed therapy is individualized and impacted by desmoid stage, severity, postsurgical anatomy, and consequences of disease. Medical therapy consists of options in multiple classes of drugs: nonsteroidal anti-inflammatory drugs, hormonal therapy, tyrosine kinase inhibitors, and cytotoxic agents. Surgical excision is sometimes an option, but can be limited by common location of disease at the root of the small bowel mesentery. Palliative surgical treatments are often considered in management of desmoid disease. Intestinal transplantation for severe desmoid disease is an emerging and promising option, though long-term data on efficacy and survival is limited.
RESUMEN
BACKGROUND & AIMS: Patients with early-onset colorectal cancer (eoCRC) are managed according to guidelines that are not age-specific. A multidisciplinary international group (DIRECt), composed of 69 experts, was convened to develop the first evidence-based consensus recommendations for eoCRC. METHODS: After reviewing the published literature, a Delphi methodology was used to draft and respond to clinically relevant questions. Each statement underwent 3 rounds of voting and reached a consensus level of agreement of ≥80%. RESULTS: The DIRECt group produced 31 statements in 7 areas of interest: diagnosis, risk factors, genetics, pathology-oncology, endoscopy, therapy, and supportive care. There was strong consensus that all individuals younger than 50 should undergo CRC risk stratification and prompt symptom assessment. All newly diagnosed eoCRC patients should receive germline genetic testing, ideally before surgery. On the basis of current evidence, endoscopic, surgical, and oncologic treatment of eoCRC should not differ from later-onset CRC, except for individuals with pathogenic or likely pathogenic germline variants. The evidence on chemotherapy is not sufficient to recommend changes to established therapeutic protocols. Fertility preservation and sexual health are important to address in eoCRC survivors. The DIRECt group highlighted areas with knowledge gaps that should be prioritized in future research efforts, including age at first screening for the general population, use of fecal immunochemical tests, chemotherapy, endoscopic therapy, and post-treatment surveillance for eoCRC patients. CONCLUSIONS: The DIRECt group produced the first consensus recommendations on eoCRC. All statements should be considered together with the accompanying comments and literature reviews. We highlighted areas where research should be prioritized. These guidelines represent a useful tool for clinicians caring for patients with eoCRC.

BACKGROUND AND AIMS: The true rate of gastric cancer (GC) in juvenile polyposis syndrome (JPS) is unknown because of its rarity and ascertainment bias in published literature. To better assess this, we conducted a systematic review and meta-analysis. METHODS: MEDLINE, Embase, and Scopus databases were searched for the key words juvenile polyposis syndrome, juvenile polyps, stomach cancer, GC, SMAD4, BMPR1A, hamartomatous polyposis syndrome, hamartomas, and hereditary cancers for studies reporting upper GI manifestations in JPS. The primary outcome was the reported occurrence of GC in JPS. We then compared GC occurrence based on the presence or absence of pathogenic germline variants (PGVs) and in untested patients. RESULTS: Eleven studies including 637 patients were included. The pooled occurrence of GC was 3.5% (95% confidence interval [CI], 1.8-5.2; I2 = 12.3%) at a median age of 42.5 years (range, 15-57.6). The pooled occurrence of GC in patients with SMAD4 PGV was 10.1% (95% CI, 3.2-16.8%; I2 = 54.7%). GC was reported in only 1 BMPR1A PGV carrier and was not reported in patients without an identifiable PGV. In patients with prior germline testing, the risk of GC was higher in SMAD4 PGV carriers (odds ratio, 11.6; 95% CI, 4.6-29.4; I2 = 18.3%) compared with patients without SMAD4 PGV. In JPS patients with unknown status of germline testing, pooled occurrence of GC was 7.5% (95% CI, 0-15.5). There was an overall moderate risk of bias in the studies. CONCLUSIONS: GC is highest in SMAD4-associated JPS and was not reported in patients without identifiable PGVs. The value of GC surveillance in BMPR1A PGV carriers and JPS patients without an identifiable PGV is questionable. Germline testing should be performed in all JPS patients to inform GC risk discussion and utility of surveillance.

BACKGROUND AND AIMS: Lynch syndrome (LS) is the most common hereditary cause of colorectal cancer (CRC) and endometrial cancer (EC). Although colonoscopy reduces CRC in LS, the protection is variable. We assessed the prevalence and incidence of neoplasia in LS during surveillance colonoscopy in the United States and factors associated with advanced neoplasia. METHODS: Patients with LS undergoing ≥1 surveillance colonoscopy and with no personal history of invasive CRC or colorectal surgery were included. Prevalent and incident neoplasia was defined as occurring <6 months before and ≥6 months after germline diagnosis of LS, respectively. We assessed advanced adenoma (AA), CRC, and the impact of mismatch repair pathogenic variant (PV) and typical LS cancer history (personal history of EC and/or family history of EC/CRC) on outcome. RESULTS: A total of 132 patients (inclusive of 112 undergoing prevalent and incident surveillance) were included. The median examination interval and duration of prevalent and incident surveillance was .88 and 1.06 years and 3.1 and 4.6 years, respectively. Prevalent and incident AA were detected in 10.7% and 6.1% and invasive CRC in 0% and 2.3% of patients. All incident CRC occurred in MSH2 and MLH1 PV carriers and only 1 (.7%) while under surveillance in our center. AAs were detected in both LS cancer history cohorts and represented in all PVs. CONCLUSIONS: In a U.S. cohort of LS, advanced neoplasia rarely occurred over annual surveillance. CRC was diagnosed only in MSH2/MLH1 PV carriers. AAs occurred regardless of PV or LS cancer history. Prospective studies are warranted to confirm our findings.

BACKGROUND: The incidence of early-onset colorectal cancer (EOCRC) is rapidly increasing. Pathogenic germline variants (PGVs) are detected in 16% to 20% of patients who have EOCRC, highlighting a need for genetic counseling (GC) and multigene panel testing in these patients. We aimed to determine the rate of referral to GC and uptake and outcomes of germline testing in patients with EOCRC. METHODS: We conducted a retrospective cohort study of patients aged <50 years diagnosed with colorectal cancer (CRC) from 2010 to 2019 at Cleveland Clinic. Demographic data were extracted, including age, sex, self-reported race, and family history of CRC. The proportions of patients with GC referral and completion of GC and genetic testing were investigated, and genetic testing results were analyzed. Multivariable logistic regression analysis was conducted to identify factors independently associated with GC referral and uptake. RESULTS: A total of 791 patients with EOCRC (57% male and 43% female) were included; 62% were referred for GC, and of those who were referred, 79% completed a GC appointment and 77% underwent genetic testing. Of those who underwent testing, 21% had a PGV detected; 82% were in known CRC-associated genes, with those associated with Lynch syndrome and familial adenomatous polyposis the most common, and 11% were in other actionable genes. Referral to GC was positively associated with family history of CRC (odds ratio [OR], 2.11; 95% CI, 1.51-2.96) and more recent year of diagnosis (2010-2013 vs 2017-2019; OR, 5.36; 95% CI, 3.59-8.01) but negatively associated with older age at diagnosis (OR, 0.89; 95% CI, 0.86-0.92). CONCLUSIONS: Referral to GC for patients with EOCRC is increasing over time; however, even in recent years, almost 25% of patients were not referred for GC. We found that 1 in 5 patients with EOCRC carry actionable PGVs, highlighting the need for health systems to implement care pathways to optimize GC referral and testing in all patients with EOCRC.

BACKGROUND: Redo ileocolic resection for recurrent Crohn's disease is associated with increased technical complexity and higher complication rates compared to primary resection. Literature concerning redo surgery for recurrent Crohn's disease is scarce and it is controversial whether a redo is a risk factor for postoperative anastomotic leak. OBJECTIVE: This study aimed to hypothesized that redo ileocolic resection for Crohn's disease is an independent risk factor for anastomotic leak. DESIGN: Retrospective, case-control study from 1994 to 2019 with multivariate analysis and propensity score weighting. SETTING: Quaternary, IBD-referral center. PATIENTS: Adult patients aged >18 years were included in the study. INTERVENTIONS: Primary or redo ileocolic resection with an anastomosis, with or without diverting ileostomy. MAIN OUTCOME MEASURES: Thirty-day anastomotic leak rate. RESULTS: A total of 991 patients (56% primary and 44% redo ileocolic resections) were included. Patients who underwent redo resection were significantly older with more comorbidities, fewer medications, and less fistulizing disease compared to the primary group. On univariate analysis, patients who underwent redo resection had more overall complications (50.5% vs 36.2%, p < 0.001), and the cumulative number of prior ileocolic resections was significantly associated with increased risk for overall morbidity ( p < 0.001). There were 31 (3%) anastomotic leaks; leak rates did not differ between groups ( p = 0.60). Multivariable analysis indicated that extensive adhesiolysis ( p < 0.001), ileostomy omission ( p = 0.009), and intraoperative abscess/fistula ( p = 0.02) were independently associated with leaks but not redo resection ( p = 0.27). Patients with 0, 1, 2, or 3 of these risk factors had observed leak rates of 1.1%, 1.3%, 6.0%, and 11.6.% ( p = 0.03), respectively. LIMITATIONS: The limitations of this study were selection bias, referral bias, and single quaternary center. CONCLUSIONS: Compared to primary procedures, redo ileocolic resection for recurrent Crohn's disease is associated with increased overall morbidity but not anastomotic leak.

Los pacientes de reintervención eran significativamente mayores con más comorbilidades, menos medicamentos y menos enfermedad fistulizante en comparación con el grupo primario. En el análisis univariado, los pacientes reoperados tuvieron más complicaciones generales (50,5% frente a 36,2%, p < 0,001) y el número acumulado de resecciones ileocólicas previas se asoció significativamente con un mayor riesgo de morbilidad general ( p < 0,001). Hubo 31 (3%) fugas anastomóticas; las tasas de fuga no difirieron entre los grupos ( p = 0,6). El análisis multivariado indicó que la adhesiolisis extensa ( p < 0,001), la omisión de ileostomía ( p = 0,009) y el absceso/fístula intraoperatorios ( p = 0,02) se asociaron de forma independiente con fugas, pero no con nueva resección ( p = 0,27). Los pacientes con 0, 1, 2 o 3 de estos factores de riesgo observaron tasas de fuga del 1,1%, 1,3%, 6,0% y 11,6% ( p = 0,03), respectivamente.LIMITACIONES:Sesgo de selección, Sesgo de referencia, un centro de cuarto nivelCONCLUSIÓN:En comparación con los procedimientos primarios, la resección ileocólica para la enfermedad de Crohn recurrente se asocia con una mayor morbilidad general, pero no con una fuga anastomótica.

BACKGROUND: Total neoadjuvant therapy is an alternative to neoadjuvant chemoradiation alone for rectal cancer and has the benefits of more completion of planned therapy, increased downstaging, earlier treatment of micrometastases, and assessment of chemosensitivity; however, it may increase surgical complications, especially with increased radiation-to-surgery interval. OBJECTIVE: The study aimed to determine the impact of total neoadjuvant therapy on postoperative complications compared with neoadjuvant chemoradiation alone. DESIGN: Retrospective cohort study. SETTINGS: Single tertiary referral center. PATIENTS: The patient included was a stage II/III rectal cancer patient who underwent total neoadjuvant therapy or long-course neoadjuvant chemoradiation followed by surgical resection from 2018-2020. MAIN OUTCOME MEASURES: The main outcome measures included severe postoperative complications (Clavien-Dindo grade ≥3). RESULTS: Of 181 patients, 86 (47.5%) underwent total neoadjuvant therapy and 95 (52.5%) underwent neoadjuvant chemoradiation. There was no difference in severe postoperative complications or any complications. There was also no difference in the rate of complete total mesorectal excision or negative circumferential margin. Total neoadjuvant therapy had a mean operative time of 355.5 minutes and estimated blood loss of 263.6 mL compared with 326.7 minutes and 297.5 mL in the neoadjuvant chemoradiation group. Total neoadjuvant therapy patients had a lower mean lymph node yield than neoadjuvant chemoradiation patients. On multivariable analysis, total neoadjuvant therapy was associated with increased operative time (OR, 1.19; p < 0.001) and estimated blood loss (OR, 1.22; p < 0.001) and decreased lymph node yield (OR, 0.67; p < 0.001). There was no difference in severe complications or any complications. LIMITATIONS: Selection bias uncontrolled by modeling. CONCLUSIONS: We found no difference in risk of postoperative complications between patients who received total neoadjuvant therapy vs neoadjuvant chemoradiation. Total neoadjuvant therapy patients had longer operations and greater estimated blood loss. This may be a reflection of increased operative difficulty because of increased radiation-to-surgery interval and/or the effects of chemotherapy; however, the absolute differences were small and, therefore, should be interpreted cautiously.

IMPACTO DE LA TERAPIA NEOADYUVANTE TOTAL EN LOS RESULTADOS POSOPERATORIOS DESPUS DE UNA PROCTECTOMA POR CNCER DE RECTO: ANTECEDENTES:La terapia neoadyuvante total es una alternativa a la quimiorradiación neoadyuvante sola para el cáncer de recto y tiene los beneficios de una mayor finalización de la terapia planificada, mayor reducción del estadiage, tratamiento más temprano de las micrometástasis y evaluación de la quimiosensibilidad; sin embargo, puede aumentar las complicaciones quirúrgicas, especialmente con un mayor intervalo entre la radiación y la cirugía.OBJETIVO:Determinar el impacto de la terapia neoadyuvante total sobre las complicaciones posoperatorias en comparación con la quimiorradiación neoadyuvante sola.DISEÑO:Estudio de cohorte retrospectivo.ENTORNO CLINICO:Centro único de referencia terciario.PACIENTES:Paciente con cáncer de recto en estadio II/III que se sometieron a terapia neoadyuvante total o quimiorradiación neoadyuvante de larga duración seguida de resección quirúrgica entre 2018 y 2020.PRINCIPALES MEDIDAS DE RESULTADO:Complicaciones postoperatorias graves (grado de Clavien-Dindo ≥3).RESULTADOS:De 181 pacientes, 86 (47,5%) se sometieron a terapia neoadyuvante total y 95 (52,5%) se sometieron a quimiorradioterapia neoadyuvante. No hubo diferencia en las complicaciones postoperatorias graves o cualquier otra complicación. Tampoco hubo diferencia en la tasa de escisión mesorrectal total completa o margen circunferencial negativo. La terapia neoadyuvante total tuvo un tiempo operatorio promedio de 355,5 minutos y una pérdida de sangre estimada de 263,6 ml en comparación con 326,7 minutos y 297,5 ml en el grupo de quimiorradiación neoadyuvante. Los pacientes con terapia neoadyuvante total tuvieron una media de ganglios linfáticos más bajo en comparación con los pacientes con quimiorradioterapia neoadyuvante. En el análisis multivariable, la terapia neoadyuvante total se asoció con un mayor tiempo operatorio (OR = 1,19, p < 0,001) y pérdida de sangre estimada (OR = 1,22, p < 0,001) y menor cantidad los ganglios linfáticos (OR = 0,67, p < 0,001). No hubo diferencia en las complicaciones graves o cualquier complicación.LIMITACIONES:Sesgo de selección no controlado por modelado.CONCLUSIONES:No encontramos diferencias en el riesgo de complicaciones postoperatorias entre los pacientes que recibieron terapia neoadyuvante total versus quimiorradiación neoadyuvante. Los pacientes con terapia neoadyuvante total tuvieron operaciones más prolongadas y una mayor pérdida de sangre estimada. Esto puede ser un reflejo de una mayor dificultad quirúrgica como resultado de un mayor intervalo entre la radiación y la cirugía y/o los efectos de la quimioterapia; sin embargo, las diferencias absolutas fueron pequeñas y, por lo tanto, deben interpretarse con cautela.

BACKGROUND: Colorectal resections have relatively high rates of surgical site infections causing significant morbidity. Incisional negative pressure wound therapy was introduced to improve wound healing of closed surgical incisions and to prevent surgical site infections. OBJECTIVE: This randomized controlled trial aimed to investigate the effect of incisional NPWT on superficial surgical site infections in high-risk, open, reoperative colorectal surgery. DESIGN: This was a single-center randomized controlled trial conducted between July 2015-October 2020. Patients were randomly assigned to incisional negative pressure wound therapy or standard gauze dressing with a 1:1 ratio. A total of 298 patients were included. SETTINGS: This study was conducted at the colorectal surgery department of a tertiary-level hospital. PATIENTS: This study included patients older than 18 years who underwent elective reoperative open colorectal resections. Patients were excluded who had open surgery within the past 3 months, who had active surgical site infection, and who underwent laparoscopic procedures. MAIN OUTCOME MEASURES: The primary outcome was superficial surgical site infection within 30 days. Secondary outcomes were deep and organ-space surgical site infections within 7 days and 30 days, postoperative complications, and length of hospital stay. RESULTS: A total of 149 patients were included in each arm. The mean age was 51 years, and 49.5% were women. Demographics, preoperative comorbidities, and preoperative albumin levels were comparable between the groups. Overall, most surgeries were performed for IBD, and 77% of the patients had an ostomy fashioned during the surgery. No significant difference was found between the groups in 30-day superficial surgical site infection rate (14.1% in control versus 9.4% in incisional negative pressure wound therapy; p = 0.28). Deep and organ-space surgical site infections rates at 7 and 30 days were also comparable between the groups. Postoperative length of stay and complication rates (Clavien-Dindo grade) were also comparable between the groups. LIMITATIONS: The patient population included in the trial consisted of a selected group of high-risk patients. CONCLUSIONS: Incisional negative pressure wound therapy was not associated with reduced superficial surgical site infection or overall complication rates in patients undergoing high-risk reoperative colorectal resections.

Los pacientes fueron aleatorizados para recibir tratamiento para heridas incisionales con presión negativa o vendaje de gasa estándar en una proporción de 1:1. Se incluyeron un total de 298 pacientes.AJUSTE:Este estudio se realizó en el departamento de cirugía colorrectal de un hospital de tercer nivel.PACIENTES:Se incluyeron pacientes mayores de 18 años que se fueron sometidos a resecciones colorrectales abiertas, re operatorias y electivas. Se excluyeron aquellos pacientes que tuvieron cirugía abierta en los últimos 3 meses, con infección activa del sitio quirúrgico y que fueron sometidos a procedimientos laparoscópicos.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue infección superficial del sitio quirúrgico dentro de los 30 días. Los resultados secundarios fueron infecciones del sitio quirúrgico profundas y del espacio orgánico dentro de los 7 y 30 días, las complicaciones posoperatorias y la duración de la estancia hospitalaria.RESULTADOS:Se incluyeron un total de 149 pacientes en cada brazo. La edad media fue de 51 años y el 49,5% fueron mujeres. La demografía, las comorbilidades preoperatorias y los niveles de albúmina preoperatoria fueron comparables entre los grupos. En general, la mayoría de las cirugías fueron realizadas por enfermedad inflamatoria intestinal y al 77 % de los pacientes se les confecciono una ostomía durante la cirugía. No hubo diferencias significativas entre los grupos en la tasa de infección del sitio quirúrgico superficial a los 30 días (14,1 % en el control frente a 9,4 % en el tratamiento de herida incisional con presión negativa, p = 0,28). Las tasas de infecciones del sitio quirúrgico profundas y del espacio orgánico a los 7 y 30 días también fueron comparables entre los grupos. La duración de la estancia postoperatoria y las tasas de complicaciones (Clavien-Dindo Graduacion) también fueron comparables entre los grupos.LIMITACIONES:La población de pacientes incluida en el ensayo consistió en un grupo seleccionado de pacientes de alto riesgo.CONCLUSIONES:Video Resumen en http://links.lww.com/DCR/B956 .

BACKGROUND: Colonic polyposis of unknown etiology (CPUE) is defined as ≥10 cumulative colonic adenomas without a detectable germline pathogenic variant. Surveillance for patients with >100 adenomas is recommended, similar to patients with familial adenomatous polyposis. The utility of extra-colonic screening in patients with 10 to <100 adenomas is not well established. METHODS: All CPUE patients seen at our center between 2003 and 2022 were included. Patients were categorized based on the range of cumulative colorectal adenoma count: 10 to 19, 20 to 99, and ≥100. RESULTS: In all, 150 patients were identified of which 20(13.3%) had 10 to 19 cumulative adenomas, 79(52.7%) had 20 to 99 adenomas, and 51(34.0%) had ≥100 adenomas. Compared with patients with 10 to 19 and 20 to 99, patients with ≥100 adenomas were younger (mean 51 vs. 52 vs. 42 y, respectively). Of patients who underwent esophagogastroduodenoscopy, duodenal adenomas were found in 33.3%, 10.1%, and 38% in the 3 groups, respectively, P=0.002. Ampullary adenomas were significantly more common in the ≥100 adenoma group (14.8%, P=0.019) compared with 8.3% and 2.9% in the 10 to 19 and 20 to 99 groups, respectively. Thyroid nodules ≥1 cm were not detected in patients with 10 to 19 adenomas but were found in 23.3% and 14.3% of patients with 20 to 99 and ≥100 adenomas, respectively (P=0.254). CONCLUSION: In our cohort, duodenal and gastric adenomas occurred in CPUE patients with adenoma count 10 to ≥100 at a relatively high proportion. We recommend a baseline esophagogastroduodenoscopy in all patients with CPUE. While clinically significant thyroid nodules were not detected in patients with 10 to 19 adenomas, they occurred in about one-fifth of the patients with ≥20 adenomas, indicating that thyroid ultrasound is prudent.
RESUMEN
AIM: Due to their rarity, the management of colorectal gastrointestinal stromal tumours (CR GISTs) is still under debate. The aim of this study was to assess prognostic factors. METHOD: We performed a retrospective review of patients who underwent surgery with curative intent for CR GIST at our centre from 2002 to 2019. Factors associated with overall (OS) and recurrence-free survival (RFS) were analysed. RESULTS: Fifty-six patients were included [median age 63 years, 29 (52%) female, 30 (54%) Miettinen high-risk, 40 (71%) with rectal GIST]. Nineteen (34%) patients received perioperative (neoadjuvant and/or adjuvant) imatinib. All cases of colonic GIST had an R0 resection, compared with 28 (70%) of rectal GISTs. After a median follow-up of 97 months (interquartile range 48-155 months), 14 (25%) deaths and 14 (25%) recurrences occurred. In the high-risk cohort, factors associated with improved RFS were R0 resection (OR 0.19, 95% CI 0.1-0.5, p = 0.002) and perioperative imatinib (OR 0.33, 95% CI 0.42-0.97, p = 0.04). Patients who had received perioperative imatinib had longer RFS (60% vs. 11% at 5 years, p = 0.006) but not OS. In rectal GISTs, 5-year OS was 85% for R0 and 70% for R1 resections (p = 0.164) and 5-year RFS was 85% for R0 and 12% for R1 resection (p < 0.001). When stratifying patients by perioperative imatinib, there were no differences in OS or RFS in the R0 or R1 groups. CONCLUSION: Perioperative imatinib and R0 resection were associated with improved RFS in high-risk patients with CR GIST. In patients with rectal GIST, R1 resection was associated with worse RFS irrespective of perioperative imatinib treatment.
