RESUMEN
AIM: Minimally invasive surgery has been increasingly adopted for locally advanced colon cancer. However, evidence comparing robotic (RRC) versus laparoscopic right colectomy (LRC) for nonmetastatic pT4 cancers is lacking. METHODS: This was a multicentre propensity score-matched (PSM) study of a cohort of consecutive patients with pT4 right colon cancer treated with RRC or LRC. The two surgical approaches were compared in terms of R0, number of lymph nodes harvested, intra- and postoperative complication rates, overall (OS), and disease-free survival (DFS). RESULTS: Among a total of 200 patients, 39 RRC were compared with 78 PS-matched LRC patients. The R0 rate was similar between RRC and LRC (92.3% vs. 96.2%, respectively; p = 0.399), as was the odds of retrieving 12 or more lymph nodes (97.4% vs. 96.2%; p = 1). No significant difference was noted for the mean operating time (192.9 min vs. 198.3 min; p = 0.750). However, RRC was associated with fewer conversions to laparotomy (5.1% vs. 20.5%; p = 0.032), less blood loss (36.9 vs. 95.2 mL; p < 0.0001), fewer postoperative complications (17.9% vs. 41%; p = 0.013), a shorter time to flatus (2 vs. 2.8 days; p = 0.009), and a shorter hospital stay (6.4 vs. 9.5 days; p < 0.0001) compared with LRC. These results were confirmed even when converted procedures were excluded from the analysis. The 1-, 3- and 5-year OS (p = 0.757) and DFS (p = 0.321) did not significantly differ between RRC and LRC. CONCLUSION: Adequate oncological outcomes are observed for RRC and LRC performed for pT4 right colon cancer. However, RRC is associated with lower conversion rates and improved short-term postoperative outcomes.

AIM: Recent evidence challenges the current standard of offering surgery to patients with ileocaecal Crohn's disease (CD) only when they present complications of the disease. The aim of this study was to compare short-term results of patients who underwent primary ileocaecal resection for either inflammatory (luminal disease, earlier in the disease course) or complicated phenotypes, hypothesizing that the latter would be associated with worse postoperative outcomes. METHOD: A retrospective, multicentre comparative analysis was performed including patients operated on for primary ileocaecal CD at 12 referral centres. Patients were divided into two groups according to indication of surgery for inflammatory (ICD) or complicated (CCD) phenotype. Short-term results were compared. RESULTS: A total of 2013 patients were included, with 291 (14.5%) in the ICD group. No differences were found between the groups in time from diagnosis to surgery. CCD patients had higher rates of low body mass index, anaemia (40.9% vs. 27%, p < 0.001) and low albumin (11.3% vs. 2.6%, p < 0.001). CCD patients had longer operations, lower rates of laparoscopic approach (84.3% vs. 93.1%, p = 0.001) and higher conversion rates (9.3% vs. 1.9%, p < 0.001). CCD patients had a longer hospital stay and higher postoperative complication rates (26.1% vs. 21.3%, p = 0.083). Anastomotic leakage and reoperations were also more frequent in this group. More patients in the CCD group required an extended bowel resection (14.1% vs. 8.3%, p: 0.017). In multivariate analysis, CCD was associated with prolonged surgery (OR 3.44, p = 0.001) and the requirement for multiple intraoperative procedures (OR 8.39, p = 0.030). CONCLUSION: Indication for surgery in patients who present with an inflammatory phenotype of CD was associated with better outcomes compared with patients operated on for complications of the disease. There was no difference between groups in time from diagnosis to surgery.

BACKGROUND: Recently, positive circumferential resection margin has been found to be an indicator of advanced disease with a high risk of distant recurrence rather than local recurrence. OBJECTIVE: The study aimed to analyze the prognostic impact of the circumferential resection margin on long-term oncological outcomes in patients with rectal cancer. DESIGN: This was a multicenter, propensity score-matched (2:1) analysis comparing the positive and negative circumferential resection margins. SETTINGS: The study was conducted at 5 high-volume centers in Spain. PATIENTS: Patients who underwent total mesorectal excision with curative intent for middle-low rectal cancer between 2006 and 2014 were included. MAIN OUTCOME MEASURES: The main outcomes were local recurrence, distant recurrence, overall survival, and disease-free survival. RESULTS: The unmatched initial cohort consisted of 1599 patients, of whom 4.9% had a positive circumferential resection margin. After matching, 234 patients were included (156 with a negative circumferential margin and 78 with a positive circumferential margin). The median follow-up period was 52.5 (22.0-69.5) months. Local recurrence was significantly higher in patients with a positive circumferential margin (33.3% vs 11.5%; p < 0.001). Distant recurrence was similar in both groups (46.2% vs 42.3%; p = 0.651). There were no statistically significant differences in 5-year overall survival (48.6% vs 43.6%; p = 0.14). Disease-free survival was lower in patients with a positive circumferential margin (36.1% vs 52.3%; p = 0.026). LIMITATIONS: This study was limited by its retrospective design. The different neoadjuvant treatment options were not included in the propensity score. CONCLUSIONS: The positive circumferential resection margin was associated with a higher local recurrence rate and worse disease-free survival in comparison with the negative circumferential resection margin. However, the positive circumferential resection margin was not a prognostic indicator of distant recurrence and overall survival. See Video Abstract at http://links.lww.com/DCR/B950 . VALOR PRONSTICO DEL MARGEN DE RESECCIN CIRCUNFERENCIAL DESPUS DE LA CIRUGA CURATIVA PARA EL CNCER DE RECTO UN ANLISIS MULTICNTRICO EMPAREJADO POR PUNTAJE DE PROPENSIN: ANTECEDENTES:En los últimos años, se ha encontrado que el margen de resección circunferencial positivo es un indicador de enfermedad avanzada con alto riesgo de recurrencia a distancia más que de recurrencia local.OBJETIVO:El objetivo fue analizar el impacto pronóstico del margen de resección circunferencial sobre la recidiva local, a distancia y las tasas de supervivencia en pacientes con cáncer de recto.DISEÑO:Este fue un análisis multicéntrico emparejado por puntaje de propensión 2: 1 que comparó el margen de resección circunferencial positivo y negativo.AJUSTES:El estudio se realizó en 5 centros Españoles de alto volumen.PACIENTES:Se incluyeron pacientes sometidos a escisión total de mesorrecto con intención curativa por cáncer de recto medio-bajo entre 2006-2014. Las características clínicas e histológicas se utilizaron para el emparejamiento.PRINCIPALES MEDIDAS DE RESULTADO:Los resultadoes principales fueron la recurrencia local, la recurrencia a distancia, la supervivencia global y libre de enfermedad.RESULTADOS:La cohorte inicial no emparejada consistió en 1599 pacientes; El 4,9% tuvo un margen de resección circunferencial positivo. Tras el emparejamiento se incluyeron 234 pacientes (156 con margen circunferencial negativo y 78 con margen circunferencial positivo). La mediana del período de seguimiento fue de 52,5 meses (22,0-69,5). La recurrencia local fue significativamente mayor en pacientes con margen circunferencial positivo, 33,3% vs 11,5% [HR 3,2; IC 95%: 1,83-5,43; p < 0,001]. La recidiva a distancia fue similar en ambos grupos (46,2 % frente a 42,3 %) [HR 1,09, IC 95 %: 0,78-1,90; p = 0,651]. No hubo diferencias significativas en la supervivencia global a 5 años (48,6 % frente a 43,6 %) [HR 1,09, IC 95 %: 0,92-1,78; p = 0,14]; La supervivencia libre de enfermedad fue menor en pacientes con margen circunferencial positivo, 36,1% vs 52,3% [HR 1,5; IC 95%: 1,05-2,06; p = 0,026].LIMITACIONES:Este estudio estuvo limitado por el diseño retrospectivo. Las diferentes opciones de tratamientos neoadyuvantes no se han incluido en la puntuación de propensión.CONCLUSIONES:El margen de resección circunferencial positivo se asocia con una mayor tasa de recurrencia local y peor supervivencia libre de enfermedad en comparación con el margen de resección circunferencial negativo. Sin embargo, el margen de resección circunferencial positivo no fue un indicador pronóstico de recidiva a distancia ni de supervivencia global.

BACKGROUND: This study aimed to compare the short- and long-term outcomes of robotic (RRC-IA) versus laparoscopic (LRC-IA) right colectomy with intracorporeal anastomosis using a propensity score matching (PSM) analysis based on a large European multicentric cohort of patients with nonmetastatic right colon cancer. METHODS: Elective curative-intent RRC-IA and LRC-IA performed between 2014 and 2020 were selected from the MERCY Study Group database. The two PSM-groups were compared for operative and postoperative outcomes, and survival rates. RESULTS: Initially, 596 patients were selected, including 194 RRC-IA and 402 LRC-IA patients. After PSM, 298 patients (149 per group) were compared. There was no statistically significant difference between RRC-IA and LRC-IA in terms of operative time, intraoperative complication rate, conversion to open surgery, postoperative morbidity (19.5% in RRC-IA vs. 26.8% in LRC-IA; p = 0.17), or 5-yr survival (80.5% for RRC-IA and 74.7% for LRC-IA; p = 0.94). R0 resection was obtained in all patients, and > 12 lymph nodes were harvested in 92.3% of patients, without group-related differences. RRC-IA procedures were associated with a significantly higher use of indocyanine green fluorescence than LRC-IA (36.9% vs. 14.1%; OR: 3.56; 95%CI 2.02-6.29; p < 0.0001). CONCLUSION: Within the limitation of the present analyses, there is no statistically significant difference between RRC-IA and LRC-IA performed for right colon cancer in terms of short- and long-term outcomes.

AIM: Operation time (OT) is a key operational factor influencing surgical outcomes. The present study aimed to analyse whether OT impacts on short-term outcomes of minimally-invasive right colectomies by assessing the role of surgical approach (robotic [RRC] or laparoscopic right colectomy [LRC]), and type of ileocolic anastomosis (i.e., intracorporal [IA] or extra-corporal anastomosis [EA]). METHODS: This was a retrospective analysis of the Minimally-invasivE surgery for oncological Right ColectomY (MERCY) Study Group database, which included adult patients with nonmetastatic right colon adenocarcinoma operated on by oncological RRC or LRC between January 2014 and December 2020. Univariate and multivariate analyses were used. RESULTS: The study sample was composed of 1549 patients who were divided into three groups according to the OT quartiles: (1) First quartile, <135 min (n = 386); (2) Second and third quartiles, 135-199 min (n = 731); and (3) Fourth quartile ≥200 min (n = 432). The majority (62.7%) were LRC-EA, followed by LRC-IA (24.3%), RRC-IA (11.1%), and RRC-EA (1.9%). Independent predictors of an OT ≥ 200 min included male gender, age, obesity, diabetes, use of indocyanine green fluorescence, and IA confection. An OT ≥ 200 min was significantly associated with an increased risk of postoperative noninfective complications (AOR: 1.56; 95% CI: 1.15-2.13; p = 0.004), whereas the surgical approach and the type of anastomosis had no impact on postoperative morbidity. CONCLUSION: Prolonged OT is independently associated with increased odds of postoperative noninfective complications in oncological minimally-invasive right colectomy.

AIM: Surgical site infections (SSIs) are common after colonic surgery. SSIs can cause relevant morbidity and increase costs of care. Preoperative oral antibiotics can reduce the incidence of SSIs after resection of the colon, but the role of mechanical bowel preparation (MBP) is debated. This study aims to assess the impact of a combined regimen of oral antibiotics and MBP on SSIs after colonic surgery. METHODS: An international, multicentre, pragmatic, adaptive, parallel-group, randomized controlled trial will be conducted across Europe. Adult patients scheduled to undergo elective colonic resection will be assessed for inclusion. Patients will be randomized into one of two treatment arms: (1) preoperative oral antibiotics without MBP (control); (2) preoperative oral antibiotics with MBP (experimental). All patients will receive intravenous antibiotics at anaesthetic induction. The primary aim will be 30-day SSI, assessed by a blinded nurse. Additional end-points include safety, morbidity and mortality, satisfaction with the preparation, time to return of bowel function, time to complete recovery and time to discharge, long-term results. Analyses will be performed with a modified intention-to-treat approach. Interim analyses are planned. DISCUSSION: This will be the first randomized clinical trial to assess the efficacy and safety of preoperative oral antibiotics plus MBP versus preoperative oral antibiotics only, before colonic surgery. The knowledge obtained could help to establish the ideal preparation for patients scheduled to undergo resection of the colon. Full protocol NCT04161599.

OBJECTIVE: to assess the epidemiology and features of de novo surgical diseases in patients admitted with COVID-19, and their impact on patients and healthcare system. SUMMARY BACKGROUND DATA: Gastrointestinal involvement has been described in COVID-19; however, no clear figures of incidence, epidemiology and economic impact exist for de-novo surgical diseases in hospitalized patients. METHODS: This is a prospective study including all patients admitted with confirmed SARS-CoV-2 rT-PCR, between 1 March and 15 May 2020 at two Tertiary Hospitals. Patients with known surgical disease at admission were excluded. Sub-analyses were performed with a consecutive group of COVID-19 patients admitted during the study period, who did not require surgical consultation. RESULTS: Ten out of 3089 COVID-19 positive patients (0.32%) required surgical consultation. Among those admitted in intensive care unit (ICU) incidence was 1.9%. Mortality was 40% in patients requiring immediate surgery and 20% in those suitable for conservative management. The overall median length of stay (LOS) of patients admitted to ICU was longer in those requiring surgical consultation compared with those who did not (51.5 vs 25 days, p = 0.0042). Patients requiring surgical consultation and treatment for de-novo surgical disease had longer median ICU-LOS (31.5 vs 12 days, p = 0.0004). A median of two post-surgical complications were registered for each patient undergoing surgery. Complication-associated costs were as high as 38,962 USD per patient. CONCLUSIONS: Incidence of de-novo surgical diseases is low in COVID-19, but it is associated with significant morbidity and mortality. Future studies should elucidate the mechanism underlying the condition and identify strategies to prevent the need for surgery.

BACKGROUND: Povidone iodine (PVI) is a widely used antiseptic solution among surgeons. A meta-analysis based on randomized controlled trials (RCTs) was conducted to establish whether application of PVI before wound closure could reduce surgical site infection (SSI) rates. METHODS: Systematic review of MEDLINE/PubMed, Scopus, CINAHL, and Web of Science databases from inception to September 2017, with no language restrictions. Only RCTs were retrieved. The primary outcome was the SSI rate. Meta-analysis was complemented with trial sequential analysis (TSA). RESULTS: A total of 7601 patients collected from 16 RCTs were analyzed. A reduction in overall SSI rate was found (RR 0.64, 95% CI 0.48-0.85, P = 0.002, I2 = 65%), which was attributed to patients undergoing elective operations (n = 2358) and mixed elective/urgent operations (n = 2019). When RCTs of uncertain quality (n = 9) were excluded, the use of PVI before wound closure (n = 4322 patients) was not associated with a significant reduction of SSI (RR 0.81, 95% CI 0.55-1.20, P = 0.29, I2 = 51%) and was only significant in clean wounds (RR 0.25, 95% CI 0.09-0.70, P = 0.008, I2 = 0%). For the primary outcome, the TSA calculation using a relative risk reduction of 19% and an 11% proportion of control event rate (CER) with 51% of I2, the accrued information size (n = 4322) was 32.8% of the estimated optimal information size (n = 13,148). CONCLUSIONS: There is no conclusive evidence for a strong recommendation of topical PVI before wound closure to prevent SSI.

BACKGROUND: Total mesorectal excision (TME) is the standard surgery for low/mid locally advanced rectal cancer. The aim of this study was to compare three minimally invasive surgical approaches for TME with primary anastomosis (laparoscopic TME, robotic TME, and transanal TME). METHODS: Records of patients undergoing laparoscopic TME, robotic TME, or transanal TME between 2013 and 2022 according to standardized techniques in expert centres contributing to the European MRI and Rectal Cancer Surgery III (EuMaRCS-III) database were analysed. Propensity score matching was applied to compare the three groups with respect to the complication rate (primary outcome), conversion rate, postoperative recovery, and survival. RESULTS: A total of 468 patients (mean(s.d.) age of 64.1(11) years) were included; 190 (40.6%) patients underwent laparoscopic TME, 141 (30.1%) patients underwent robotic TME, and 137 (29.3%) patients underwent transanal TME. Comparative analyses after propensity score matching demonstrated a higher rate of postoperative complications for laparoscopic TME compared with both robotic TME (OR 1.80, 95% c.i. 1.11-2.91) and transanal TME (OR 2.87, 95% c.i. 1.72-4.80). Robotic TME was associated with a lower rate of grade A anastomotic leakage (2%) compared with both laparoscopic TME (8.8%) and transanal TME (8.1%) (P = 0.031). Robotic TME (1.4%) and transanal TME (0.7%) were both associated with a lower conversion rate to open surgery compared with laparoscopic TME (8.8%) (P < 0.001). Time to flatus and duration of hospital stay were shorter for patients treated with transanal TME (P = 0.003 and 0.001 respectively). There were no differences in operating time, intraoperative complications, blood loss, mortality, readmission, R0 resection, or survival. CONCLUSION: In this multicentre, retrospective, propensity score-matched, cohort study of patients with locally advanced rectal cancer, newer minimally invasive approaches (robotic TME and transanal TME) demonstrated improved outcomes compared with laparoscopic TME.

Background: The risk of conversion to open surgery is inevitably present during any minimally invasive colorectal surgical procedure. Conversions have been associated with adverse postoperative and oncologic outcomes. No previous study has evaluated the specific causes and consequences of conversion during a minimally invasive right colectomy (MIS-RC). Materials and Methods: We analyzed the Minimally invasivE surgery for oncologic Right ColectomY (MERCY) study database including patients who underwent laparoscopic or robotic RC because of colon cancer between 2014 and 2020. Descriptive analyses were performed to determine the different reasons for conversion. Uni- and multivariate logistic regressions were run to identify potential variables associated with this outcome. Cox regression analyses were used to evaluate the impact of conversion on tumor recurrence. Results: Over a total of 1574 MIS-RC, 120 (7.6%) were converted to open surgery. The main reasons for conversion were procedural difficulties related to adherences from previous abdominal surgical procedures (39.2%), or owing to large tumor size or infiltration of adjacent structures (26.7%). Only 16.7% of the conversions were caused by intraoperative medical or surgical complications. Converted patients required longer operative times and developed more postoperative complications, both overall (39.2% versus 27.5%; P = .006) and severe ones (13.3% versus 8.3%; P = .061). Male gender (odds ratio [OR] = 1.89 [95% confidence interval: 1.31-2.71]), obesity (OR = 1.99 [1.4-2.83]), prior abdominal surgery (OR = 1.68 [1.19-2.37]), and pT4 cancers (OR = 4.04 [2.86-5.69]) were independently associated with conversion. Conversion to open surgery was not significantly associated with tumor recurrence (hazard ratios = 1.395 [0.724-2.687]). Conclusions: Although conversion to open surgery during MIS-RC for cancer is associated with worsened postoperative outcomes, it seems not to impact on the oncologic prognosis.

Intracorporeal anastomoses (IA) are increasingly being used in colorectal surgery. Some data suggest that these might confer benefits compared with extracorporeal anastomoses (EA). The aim of this study is to compare the short-term complications associated with IA versus EA for minimally invasive right colectomy. This is a single-centre, retrospective study on a prospective database. Patients who underwent minimally invasive right colectomy for cancer between January 2017 and December 2019 were assessed for inclusion. The primary outcome was global 30-day morbidity. Overall, 189 patients were included, of whom 102 had IA. Global morbidity and medical complications were higher in patients with EA (23.5% vs. 40.2%, p = 0.014; 5.9% vs. 14.9%, p = 0.039, respectively). None of the patients with IA had non-infectious surgical wound complications, compared to 4.6% in the EA group (p = 0.029). No differences were found in anastomotic leakage (9.8% vs. 10.3%, p = 0.55). At multivariable analysis, EA was an independent risk factor for both surgical (OR = 3.71 95% CI: 1.06-12.91, p = 0.04) and overall complications (OR = 3.58 95% CI: 1.06-12.12, p = 0.04). IA lowers the risk for global, medical, and surgical complications with minimum risk for wound complications, without increasing the risk of AL.
RESUMEN
BACKGROUND: The effectiveness of surgical treatment for splenic flexure carcinomas (SFCs) in emergency settings remains unexplored. This study aims to compare the perioperative and long-term outcomes of different alternatives for emergency SFC resection. METHOD: This multicenter retrospective study was based on the SFC Study Group database. For the present analysis, SFC patients were selected if they had received emergency surgical resection with curative intent between 2000 and 2018. Extended right colectomy (ERC), left colectomy (LC), and segmental left colectomy (SLC) were evaluated and compared. RESULTS: The study sample was composed of 90 SFC patients who underwent emergency ERC (n = 55, 61.1%), LC (n = 18, 20%), or SLC (n = 17, 18.9%). Bowel obstruction was the most frequent indication for surgery (n = 75, 83.3%), and an open approach was chosen in 81.1% of the patients. A higher incidence of postoperative complications was observed in the ERC group (70.9%) than in the LC (44.4%) and SLC groups (47.1%), with a significant procedure-related difference for severe postoperative complications (Dindo-Clavien ≥ III; adjusted odds ratio for ERC vs. LC:7.23; 95% CI 1.51-34.66; p = 0.013). Anastomotic leakage occurred in 8 (11.2%) patients, with no differences between the groups (p = 0.902). R0 resection was achieved in 98.9% of the procedures, and ≥ 12 lymph nodes were retrieved in 92.2% of patients. Overall and disease-free survival rates at 5 years were similar between the groups and were significantly associated with stage pT4 and the presence of synchronous metastases. CONCLUSION: In the emergency setting, ERC and open surgery are the most frequently performed procedures. ERC is associated with increased odds of severe postoperative complications when compared to more conservative SFC resections. Nonetheless, all the alternatives seem to provide similar pathologic and long-term outcomes, supporting the oncological safety of more conservative resections for emergency SFCs.

BACKGROUND/AIM: The European MRI and Rectal Cancer Surgery (EuMaRCS) score was proposed to identify preoperatively difficult laparoscopic total mesorectal excision (L-TME) for locally advanced rectal cancer (LARC). This study aimed to test EuMaRCS's validity. PATIENTS AND METHODS: Data were retrieved from a European multicenter database, including patients with mid/low LARC, treated with neoadjuvant chemoradiation therapy and L-TME with primary anastomosis. The EuMaRCS score was calculated on: BMI>30 (3 points), interspinous distance<96.4 mm (2 points), ymrT stage≥T3b (4 points), and male sex (1 point). RESULTS: The sample was composed of 141 patients, of whom 23 (16.3%) had a difficult L-TME. The EuMaRCS score demonstrated high accuracy in predicting difficult surgery (AROC: 0.806, 95%CI=0.72-0.88), with a cut-off >3 being associated with the best balance in sensitivity (82.6%) and specificity (66.1%). CONCLUSION: The EuMaRCS score represents a validated tool to predict preoperatively difficult L-TME in LARC patients.

Background: Surgical site infections (SSIs) remains a concern for surgeons because of the negative impact on outcomes and health care costs. Our purpose was to assess whether topical antibiotics before primary incision closure reduced the rate of SSIs. Methods: Systematic review of MEDLINE/PubMed, Scopus, CINAHL, and Web of Science databases from inception to January 2017. Only randomized controlled trials (RCTs) were retrieved. The primary outcome was the SSI rate. Meta-analysis was complemented with trial sequential analysis (TSA). Results: Thirty-five RCTs (10,870 patients) were included. Only ß-lactams and aminoglycosides were used. A substantial reduction of the incidence of SSIs with the application of antibiotic agents before incision closure (risk ratio [RR] 0.49, 95% confidence interval [CI] 0.37-0.64) was found, which remained in the analysis of 12 RCTs after removal of studies of uncertain quality. The use of ß-lactams was effective to reduce SSI in elective surgery only (RR 0.33, 95% CI 0.13-0.85). In clean-contaminated fields and as an irrigation solution, ß-lactams did not reduce the risk of SSI. Aminoglycosides were not effective (RR 0.74, 95% CI 0.49-1.10). After TSA, the evidence accumulated was far below the optimal information size. The heterogeneity of studies was high and methodological quality of most RCTs included in the meta-analysis was uncertain. Conclusions: Results of this meta-analysis show the data present in the literature are not sufficiently robust and, therefore, the use of topical ß-lactams or aminoglycosides before incision closure to reduce SSI cannot be recommended or excluded.

INTRODUCTION: The treatment of anal fistula with the OTSC® (over-the-scope-clip) proctology device involves the placement of an elastic alloy clip called Nitinol on the internal fistula opening to achieve fistula healing. The aim of this study was to analyze preliminary results of this technique in a case series. METHODS: This was a retrospective analysis of patients who underwent OTSC® clip placement for fistula-in-ano treatment between June 2015 and March 2017 at a specialized colorectal unit. Patients with simple and complex fistulae, either previously treated or not, were included in the study. Both cryptoglandular and stable Crohn's disease fistulae were considered for this approach. Technique failure was determined by the re-appearance of anorectal suppuration or in clip-related complications. RESULTS: Ten patients were treated surgically for anal fistula with a median age of 54 years (range: 41-70years). The etiology of the fistulae was mainly cryptoglandular. Three patients had simple fistulae, whereas seven had complex disease. 80% of the patients had already undergone previous fistula surgery. No events occurred during the procedure. The success rate for healing was 60%, with a median follow-up of 15months (range: 6-26months). Three patients developed suppuration relapse and one patient required clip extraction due to invalidating anal pain. No fecal incontinence was recorded after the procedure. CONCLUSIONS: The treatment of anal fistulae with the OTSC® device is a safe sphincter-saving technique in the short term.

INTRODUCCIÓN: El tratamiento de la fístula anal con el dispositivo OTSC(R)(over-the-scope-clip) consiste en la inserción de un clip de una aleación elástica denominado Nitinol que ejerce una presión constante sobre el orificio fistuloso interno y facilita el cierre de la fístula. El objetivo de este estudio es analizar los resultados a corto plazo de esta técnica en una serie de casos. MÉTODOS: Análisis retrospectivo de una serie de casos intervenidos de cierre de fístula anal entre junio de 2015 y marzo de 2017 tratados en una unidad especializada con el dispositivo OTSC®. Se incluyeron pacientes con fístulas anales simples y complejas, tratadas previamente o sin tratamientos previos, de origen criptoglandular o por enfermedad de Crohn estable. Se consideró fracaso de la técnica a la supuración anal o complicaciones relacionadas con la inserción del clip. RESULTADOS: Se intervino a 10 pacientes con fístula anal con una mediana de edad de 54 años (rango: 41-70 años). Nueve fístulas fueron de origen criptoglandular y una por enfermedad de Crohn controlada. Tres pacientes presentaron fístulas simples y siete, complejas. El 80% de los pacientes habían presentado cirugías anales previas. La tasa de curación de la fístula fue del 60% con un seguimiento mediano de 15 meses (rango: 6-26 meses). Tres pacientes presentaron recidiva clínica y un paciente requirió extracción del clip por dolor invalidante. No hubo aparición de incontinencia fecal. CONCLUSIONES: El tratamiento de la fístula anal con el dispositivo OTSC(R) es una técnica conservadora de esfínteres segura con resultados satisfactorios a corto plazo
