European Society of Coloproctology: Guidelines for diagnosis and treatment of cryptoglandular anal fistula.

AIM: The primary aim of the European Society of Coloproctology (ESCP) Guideline Development Group (GDG) was to produce high-quality, evidence-based guidelines for the management of cryptoglandular anal fistula with input from a multidisciplinary group and using transparent, reproducible methodology. METHODS: Previously published methodology in guideline development by the ESCP has been replicated in this project. The guideline development process followed the requirements of the AGREE-S tool kit. Six phases can be identified in the methodology. Phase one sets the scope of the guideline, which addresses the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula in adult patients presenting to secondary care. The target population for this guideline are healthcare practitioners in secondary care and patients interested in understanding the clinical evidence available for various surgical interventions for anal fistula. Phase two involved formulation of the GDG. The GDG consisted of 21 coloproctologists, three research fellows, a radiologist and a methodologist. Stakeholders were chosen for their clinical and academic involvement in the management of anal fistula as well as being representative of the geographical variation among the ESCP membership. Five patients were recruited from patient groups to review the draft guideline. These patients attended two virtual meetings to discuss the evidence and suggest amendments. In phase three, patient/population, intervention, comparison and outcomes questions were formulated by the GDG. The GDG ratified 250 questions and chose 45 for inclusion in the guideline. In phase four, critical and important outcomes were confirmed for inclusion. Important outcomes were pain and wound healing. Critical outcomes were fistula healing, fistula recurrence and incontinence. These outcomes formed part of the inclusion criteria for the literature search. In phase five, a literature search was performed of MEDLINE (Ovid), PubMed, Embase (Ovid) and the Cochrane Database of Systematic Reviews by eight teams of the GDG. Data were extracted and submitted for review by the GDG in a draft guideline. The most recent systematic reviews were prioritized for inclusion. Studies published since the most recent systematic review were included in our analysis by conducting a new meta-analysis using Review manager. In phase six, recommendations were formulated, using grading of recommendations, assessment, development, and evaluations, in three virtual meetings of the GDG. RESULTS: In seven sections covering the diagnostic and therapeutic management of perianal abscess and cryptoglandular anal fistula, there are 42 recommendations. CONCLUSION: This is an up-to-date international guideline on the management of cryptoglandular anal fistula using methodology prescribed by the AGREE enterprise.

Workflows and Outcomes in Patients With Suspected Large Vessel Occlusion Stroke Triaged in Urban and Nonurban Areas.

BACKGROUND: We aim to compare the outcome of patients from urban areas, where the referral center is able to perform thrombectomy, with patients from nonurban areas enrolled in the RACECAT trial (Direct Transfer to an Endovascular Center Compared to Transfer to the Closest Stroke Center in Acute Stroke Patients With Suspected Large Vessel Occlusion). METHODS: Patients with suspected large vessel occlusion stroke, as evaluated by a Rapid Arterial Occlusion Evaluation score of ≥5, from urban catchment areas of thrombectomy-capable centers during RACECAT trial enrollment period were included in the Stroke Code Registry of Catalonia. Primary outcome was disability at 90 days, as assessed by the shift analysis on the modified Rankin Scale score, in patients with an ischemic stroke. Secondary outcomes included mortality at 90 days, rate of thrombolysis and thrombectomy, time from onset to thrombolysis, and thrombectomy initiation. Propensity score matching was used to assemble a cohort of patients with similar characteristics. RESULTS: The analysis included 1369 patients from nonurban areas and 2502 patients from urban areas. We matched 920 patients with an ischemic stroke from urban areas and nonurban areas based on their propensity scores. Patients with ischemic stroke from nonurban areas had higher degrees of disability at 90 days (median [interquartle range] modified Rankin Scale score, 3 [2-5] versus 3 [1-5], common odds ratio, 1.25 [95% CI, 1.06-1.48]); the observed average effect was only significant in patients with large vessel stroke (common odds ratio, 1.36 [95% CI, 1.08-1.65]). Mortality rate was similar between groups(odds ratio, 1.02 [95% CI, 0.81-1.28]). Patients from nonurban areas had higher odds of receiving thrombolysis (odds ratio, 1.36 [95% CI, 1.16-1.67]), lower odds of receiving thrombectomy(odds ratio, 0.61 [95% CI, 0.51-0.75]), and longer time from stroke onset to thrombolysis (mean difference 38 minutes [95% CI, 25-52]) and thrombectomy(mean difference 66 minutes [95% CI, 37-95]). CONCLUSIONS: In Catalonia, Spain, patients with large vessel occlusion stroke triaged in nonurban areas had worse neurological outcomes than patients from urban areas, where the referral center was able to perform thrombectomy. Interventions aimed at improving organizational practices and the development of thrombectomy capabilities in centers located in remote areas should be pursued. REGISTRATION: URL: https://www.

Changes in the management of IBD patients since the onset of COVID-19 pandemic. A path toward the implementation of telemedicine in Spain?

BACKGROUND: COVID-19 pandemic increased medical services demand aside from interrupting daily clinical practice for other diseases such as inflammatory bowel disease (IBD). Here we present the results of a survey to gain the perception of IBD specialists in their patient-management using telemedicine in their daily practice. METHODS: This was an observational survey study among physicians focused on IBD (gastroenterologist, surgeons, and pediatricians) members of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU), the Spanish Association of Gastroenterology (AEG), and the Spanish Association of Coloproctology (AECP), regarding changes of management of IBD patients. RESULTS: We received a total of 269 responses to the survey (from May to June 2020). Before the pandemic, nearly all the respondents reported performing very frequently their visits face-to-face (n=251, 93.3%) while, during the pandemic, the telephone visits were the most frequent visits performed (n=138, 51.3%). Regarding communication difficulties, 157 (58.4%) respondents reported the impossibility of performing a proper examination as the most relevant issue. Also, 114 (42.4%) respondents considered remote visits more time-consuming than face-to-face visits. Most gastroenterologists (n=188, 83.2%) considered patients with active perianal disease in special need of face-to-face consultation and more than half of the surgeons (n=35, 50.7%) reported having performed an immediate postoperative follow-up remotely. CONCLUSIONS: Most IBD units have implemented remote visits during the pandemic, but most professionals found them more time-consuming and unsuitable for some disease profiles. Therefore, there is a need for the development of better telemedicine systems that can meet professionals' and patients' requirements.

Inflammatory Bowel Diseases Benefit from Enhanced Recovery After Surgery [ERAS] Protocol: A Systematic Review with Practical Implications.

BACKGROUND: Enhanced Recovery After Surgery [ERAS] is widely adopted in patients undergoing colorectal surgery, with demonstrated benefits. Few studies have assessed the feasibility, safety, and effectiveness of ERAS in patients with inflammatory bowel diseases [IBD]. The aim of this study was to investigate the current adoption and outcomes of ERAS in IBD. METHODS: This PRISMA-compliant systematic review of the literature included all articles reporting on adult patients with IBD who underwent colorectal surgery within an ERAS pathway. PubMed/MEDLINE, Cochrane Library, and Web of Science were searched. Endpoints included ERAS adoption, perioperative outcomes, and ERAS items more consistently reported, with associated evidence levels [EL] [PROSPERO CRD42021238653]. RESULTS: Out of 217 studies, 16 totalling 2347 patients were included. The median number of patients treated was 50.5. Malnutrition and anaemia optimisation were only included as ERAS items in six and four articles, respectively. Most of the studies included the following items: drinking clear fluids until 2 h before the surgery, fluid restriction, nausea prophylaxis, early feeding, and early mobilisation. Only two studies included postoperative stoma-team and IBD-team evaluation before discharge. Highest EL were observed for ileocaecal Crohn's disease resection [EL2]. Median in-hospital stay was 5.2 [2.9-10.7] days. Surgical site infections and anastomotic leaks ranged between 3.1-23.5% and 0-3.4%, respectively. Complications occurred in 5.7-48%, and mortality did not exceed 1%. CONCLUSIONS: Evidence on ERAS in IBD is lacking, but this group of patients might benefit from consistent adoption of the pathway. Future studies should define if IBD-specific ERAS pathways and selection criteria are needed.

Postoperative Complications in Hemorrhoidal Disease and Special Conditions.

BACKGROUND: Hemorrhoidal disease is still one of the most prevalent proctological diseases. Pain is the most common complication after surgery but bleeding, urinary retention and perianal infection are also frequent. There is also an important group of patients, such as those with inflammatory bowel disease, pregnancy or immunosuppression, who can present an increased rate or more severe complications. OBJECTIVE: To describe the complications following different surgical and instrumental techniques for hemorrhoids in a literature review. Special situations were reviewed to determine how they affect the management of the disease. METHODS: During August 2019, a narrative review of hemorrhoid surgery complications and special situations was performed using the Pubmed MESH DATABASE. CONCLUSION: Pain, urinary retention and bleeding remain the most frequent complications after surgery for hemorrhoids; however, special situations must be taken into account in order to choose the best technique to prevent more severe complications.

Management of colorectal anastomotic leakage: differences between salvage and anastomotic takedown.

BACKGROUND: The aim of this study was to evaluate and compare the morbidity associated with 2 strategies of treatment of colorectal anastomotic leakage: surgical drainage of anastomosis with loop ileostomy versus anastomotic takedown. METHODS: An observational study of patients operated on for ileocolic or colorectal anastomotic leakage between 2001 and 2009. Patients were classified into 2 groups: group 1, salvage of the anastomosis, and group 2, anastomotic takedown. Mortality and morbidity were assessed. Morbidity and mortality of bowel restoration were also evaluated. RESULTS: Thirty-nine patients were included into group 1 and 54 into group 2. Mortality was 15% for group 1 and 37% for group 2 (P = .022). The rate of patients suitable for stoma reversal was 91% for loop ileostomy and 38% for end stoma (P < .001). Morbidity was 18% after loop ileostomy closure and 71% after end stoma reversal (P = .021). Hospitalization was 10 days and 21 days, respectively (P = .009). There was no mortality. CONCLUSIONS: Salvage of anastomosis with loop ileostomy is an effective strategy to control peritoneal sepsis for colorectal anastomotic leakage.

Circadian rhythms in the efficacy of intravenous alteplase in patients with acute ischemic stroke and middle cerebral artery occlusion.

Circadian rhythm interactions of hemostatic factors can modify tissue plasminogen activator (tPA) effects. We assess the relationship of the time frame of intravenous tPA administration with the outcome of patients with acute ischemic stroke (AIS). We studied 135 consecutive patients with AIS and transcranial duplex documented middle cerebral artery (MCA) occlusion treated with intravenous tPA. Complete recanalization was defined as total improvement on thrombolysis in brain ischemia (TIBI) grades 2 h after tPA infusion. Clinical response was evaluated by the modified Rankin scale at 90 days. We determined plasminogen activator inhibitor-1 (PAI-1) levels in 33 patients with available plasma samples before treatment. Our results are follows: 92 (68.1%) patients were treated in the diurnal (9:00-21:00) and 43 (31.8%) in the nocturnal period (21:00-9:00). Complete recanalization was recorded in 52/135 (38.5%) patients. Both the rate of complete recanalization (45.6% vs. 23.2%; p = .01) and good clinical outcome (64.1% vs. 44.2%; p = .02) were significantly higher in the group of diurnal tPA administration compared with those treated in the nocturnal period. The adjusted odds ratio (OR) of diurnal tPA treatment for complete MCA recanalization was 2.37 (95% confidence interval [CI], 1.02-5.52; p = .045). Diurnal tPA infusion significantly improved the overall distribution of scores on the modified Rankin scale, as compared with nocturnal treatment (OR, 2.07; 95% CI, 1.16-4.64 by ordinal regression analysis). Low PAI-1 levels were associated with complete recanalization but did not significantly differ between the two time frames. In conclusion, diurnal administration of tPA is associated with complete MCA recanalization and better functional outcome at 90 days in patients with AIS.

Impact of surgical specialization on emergency colorectal surgery outcomes.

OBJECTIVE: To evaluate the impact of surgeon specialization on emergency colorectal resection in terms of mortality, morbidity, and type of operation performed. DESIGN: Observational study from January 1, 1993, through December 31, 2006. SETTING: Bellvitge University Hospital, Barcelona, Spain. PATIENTS: A total of 1046 patients underwent emergency colorectal resection. Patients were classified into 2 groups: those operated on by a colorectal surgeon (CS) and those operated on by a general surgeon (GS). MAIN OUTCOME MEASURES: Preoperative variables studied were sex, age, American Society of Anesthesiologists grade, associated medical disease, presentation, reason for surgery, and type of operation. Univariate relations between predictors and outcomes were estimated, and multivariate logistic regression analysis was used to assess the prognostic effect of the combination of the variables. RESULTS: Patients in the CS group underwent a significantly higher percentage of resection and primary anastomosis. The postoperative morbidity rate was 52.2% in the CS group and 60.5% in the GS group (P = .01). The anastomotic dehiscence rate was lower in the CS group (6.2%) than in the GS group (12.1%) (P = .01). Postoperative mortality decreased among patients in the CS group (17.9%) with respect to the patients in the GS group (28.3%) (P < .001). Being operated on by a CS was predictive in both the univariate and multivariate analyses for postoperative complications and mortality, and it was the only variable with predictive value for anastomotic dehiscence. CONCLUSIONS: Specialization in colorectal surgery has a significant influence on morbidity, mortality, and anastomotic dehiscence after emergency operations.

[Long-term results of emergency surgery for colon cancer compared with elective surgery]. / Resultados a largo plazo de la cirugía urgente y electiva del cáncer de colon. Estudio comparativo.

INTRODUCTION: Currently, the mechanisms that worsen the prognosis of complicated colon cancers are still not well known. Moreover, the possible effect of using sound oncological principles in emergency surgery on long-term prognosis has not been studied in detail. AIMS: The aim of the present study was to analyze the 5-year efficacy of curative oncological surgery for complicated colon cancer performed in an emergency setting in terms of tumor recurrence and survival compared with elective surgery of uncomplicated tumors. PATIENTS AND METHOD: We performed a prospective observational cohort study in patients who underwent emergency surgery for complicated colon cancer (group 1) and patients who underwent elective surgery (group 2). Exclusion criteria were tumors of less than 15 cm from the anal verge, palliative surgery, and distant metastases. RESULTS: During the study period, 646 patients underwent surgery: there were 165 (25.5%) emergency surgeries and 481 (74.5%) elective interventions. Surgery was considered curative in 456 (70.6%) patients: 102 (22.4%) emergency and 354 (77.6%) elective surgeries. Significant differences were found in disease stage between the 2 groups (P = 0.003). The postoperative mortality rate was 12.7% in group 1 and 3.4% in group 2 (P = 0.001). When patients were stratified by TNM stage, worse 5-year cancer-related and disease-free survival rates were observed in group 1 patients with stage II tumors. No differences were found in cancer-related survival rates in stage III patients (P = 0.178). There were no significant differences in overall survival, cancer-related survival or tumor recurrence rates when group 1 was compared with a subgroup of patients in group 2 with factors of poor prognosis. CONCLUSIONS: Complicated colon cancer presents in more advanced stages and had a worse overall long-term prognosis than uncomplicated tumour. These differences decrease when patients are subclassified by tumoral stage. Overall survival and cancer-related survival rates similar to those of elective surgery can be achieved in emergency surgery when curative oncological resection is performed.
