The aim of the study was to reach consensus among experts on the possible applications of telemedicine in colorectal surgery. A group of 48 clinical practice recommendations (CPRs) was developed by a clinical guidance group based on coalescence of evidence and expert opinion. The Telemedicine in Colorectal Surgery Italian Working Group included 54 colorectal surgeons affiliated to the Italian Society of Colo-Rectal Surgery (SICCR) who were involved in the evaluation of the appropriateness of each CPR, based on published RAND/UCLA methodology, in two rounds. Stakeholders’ median age was 44.5 (IQR 36–60) years, and 44 (81%) were males. Agreement was obtained on the applicability of telemonitoring and telemedicine for multidisciplinary pre-operative evaluation. The panel voted against the use of telemedicine for a first consultation. 15/48 statements deemed uncertain on round 1 and were re-elaborated and assessed by 51/54 (94%) panelists on round 2. Consensus was achieved in all but one statement concerning the cost of a teleconsultation. There was strong agreement on the usefulness of teleconsultation during follow-up of patients with diverticular disease after an in-person visit. This e-consensus provides the boundaries of telemedicine in colorectal surgery in Italy. Standardization of infrastructures and costs remains to be better elucidated. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s13304-021-01139-8. The Coronavirus Disease 2019 (COVID-19) marked the start of a new era in many fields of medicine. Thousands of studies on COVID-19 epidemiology, diagnosis, treatment, control and impact on health resources have stormed the last year medical literature [1] . A recent survey of 1051 colorectal surgery divisions from 84 countries highlighted global changes in diagnostic and therapeutic colorectal cancer practices [2] . More than two thirds of respondents (71%) reported delays in endoscopy, radiology, surgery, histopathology, or prolonged chemoradiation therapy-to-surgery intervals. The worldwide suspended in-person elective clinical activities promoted a further increase in the use of internet and social media, yet well-known powerful tools to increase engagement and participation of patients with colorectal diseases [3] . Telemedicine (or telehealth) is the distribution of remote clinical services, including diagnosis, monitoring, and prescribing therapies by means of health-related services using information and communications technology [4] . Telemedicine in Colorectal Surgery Italian Working Group author names are listed in Appendix. In line with a recent consensus exercise defining the role of telemedicine in proctology [5] , the aim of the present study was to reach a consensus on its application in the colorectal field for screening purposes, diagnosis, follow-up, and surgical decision-making. A literature search was performed using PubMed and evidence-based medicine reviews between January 1990 and September 2020. The search strategy included the following combination of terms: (colorectal) and (telemedicine or telehealth or teleconsultation). After balancing clinical experience and common understanding of the evidence, group discussion led to shared judgments about recommendations for using telemedicine in colorectal practice. In the absence of data from Oxford level I-IV studies, the guided development group, composed of the steering committee and external advisors (Appendix), produced a final list of clinical practice recommendations (CPRs). The group was responsible for the selection of the different topics to be incorporated, and items were finalized after discussion through e-mails and teleconferences. Fifty-four experts (Telemedicine in Colorectal Surgery Italian Working Group, nominated by the Italian Society of Colorectal Surgery) on the basis of both previously published research and clinical experience in the field of colorectal practice, were invited to join the e-consensus. The consensus methodology was derived from the RAND/UCLA appropriateness method [6] , an established approach previously used in the coloproctology field [5, 7] . Forty-eight CPRs were presented electronically using an online platform ("Online Surveys," formerly Bristol Online Survey, developed by the University of Bristol) under 3 subheadings: "feasibility and pros/cons of telemedicine in colorectal surgery" (n = 14 statements), "clinical application of telemedicine in colorectal surgery" (n = 13 statements), and "legal and technical issues of a teleconsultation" (n = 21 statements). For each item, the consensus panelists were asked, "Does this recommendation lead to an expected health benefit (e.g., improved patient experience and functional capacity) that exceeds the expected negative consequences of its introduction (e.g., increased morbidity, anxiety, or denial of an investigation or treatment)?". The responses to each recommendation used a linear analog scale from 1 to 9 to assess views on the benefit-toharm ratio. Using this scale, a score of 1-3 indicated that they expected the harm of introducing the recommendation to greatly outweigh the expected benefits, and a score of 7-9 that the expected benefits to greatly outweigh the expected harm. A middle rating of 4-6 could mean either that the harm and benefits were considered approximately equal or that the panelist was unable to make a judgment for the recommendation. Responses were analyzed in accordance with the first phase of the RAND/UCLA guidance, with each recommendation classified as "appropriate," "uncertain," or "inappropriate," according to the panelists' median score and the level of disagreement. Indications with median scores in the range of 1-3 were classified as inappropriate, those in the range of 4-6 as uncertain, and those in the range of 7-9 as appropriate. "Disagreement" implied a lack of consensus because of polarization (defined as a > 17 rating of the indication in each extreme for a sample of 53-55 panelists) [6] . All indications rated "with disagreement," whatever the median, were classified as uncertain. A second round of consensus was conducted to reduce variation using the same methodology. Only statements rated "uncertain" (i.e., panel median of 4-6 or any median with disagreement) were reviewed and resubmitted for voting. Interrater agreement in each round of consensus was calculated by the Kappa statistic, which was interpreted according to the suggestions by Landis and Koch: Poor (Kappa, 0.01-0.20), slight (0.21-0.40), fair (0.41-0.60), moderate (0.61-0.80), and substantial (0.81-1.00) [8] . Fifty-four invited colorectal surgeons (male-female ratio, 4.4; median age, 44.5 [interquartile range limits, IQRL, 36-60]), members of the Italian Society of Colorectal Surgery (SICCR), agreed to join the first round of this e-consensus (response rate 100%). Overall agreement was poor (Kappa, 0.12; Suppl. Table 1 ). Eleven out of 14 (79%) proposed statements resulted appropriate. The percentage of agreement was ≥ 75% for 4 statements and 55-74% for 7 statements ( Table 1) . The statements yielding the highest level of agreement assessed the applicability of telemonitoring (i.e., decisionmaking parameters and findings sent by patients to the surgeon for a prompt reassessment). Two statements were deemed inappropriate. These concerned the exclusive use of the telemedicine during the pandemic and the possibility to perform a remote first consultation. One statement assessing the performance of postsurgical consultation remotely resulted uncertain. Four statements were uncertain, with level of agreement ranging between 35 and 43% ( Table 1 ). The uncertain statements explored the use of teleconsultation for diagnosis and decision-making in patients with oncological, diverticular and inflammatory bowel diseases (IBD). All the other statements resulted appropriate with agreement yielding 75% and above for 4 statements and 50-74% for 5 statements. The panel strongly agreed with the usefulness of the telemedicine for multidisciplinary pre-operative evaluation of colorectal cancer patients. Eighteen statements resulted appropriate, while 3 were uncertain ( Table 1) . Level of agreement was ≥ 75% for 12 (57%) statements. The highest concerned the need of a video support allowing to share photos/videos during the teleconsultation and the need of a "key-contact" as a facilitator whenever the patient is unable to use electronic platforms. The uncertain statement dealt with the cost of a teleconsultation as compared to a conventional visit, the use of social media as a tool for video calls, and the need of a phone call in the instance of technical problems during a teleconsultation. Fifty-one experts (response rate, 94%) took part to the second round. The median age was 43.5 years (IQRL 35.7-60) and ten (20%) were females. Levels of agreement were similar to round 1 (Suppl. Table 1 ). The fifteen statements resulting uncertain on round 1 were rephrased. Consensus was achieved in all but one statement (median, 4) concerning the cost of a teleconsultation, which should be 50% lower than a conventional visit ( Table 2) . Further two statements exploring the cost of a teleconsultation and its potential to replace a conventional visit, were deemed inappropriate. A total of 13 statements were found appropriate, with the highest agreement (86%) obtained by the statement regarding the usefulness of the teleconsultation during follow-up of patients with diverticular disease after a conventional visit. Besides its devastating sequalae, COVID-19 pandemic has led to several ground-breaking innovations to improve patient and provider safety. Telemedicine is certainly one of them. As expressed by Watson, the integration of telemedicine into everyday clinical practice is similar to the transition from open to laparoscopic surgery, which made surgeons 'pioneers in health care cultural change' [9] . According to our panel, telemedicine can ease the management of colorectal diseases and its usefulness is likely to continue beyond the pandemic, with the potential to reduce waiting times in health services. The panel voted against the use of telemedicine as first colorectal consultation or in the surgical decision-making process. Indeed, an outpatient evaluation was deemed appropriate to plan the correct surgical treatment according to the experts. In a previous consensus exercise defining the role of telemedicine in proctology [5] , the majority of respondents (35/47 [74%]) recommended an in-person assessment to avoid cancer misdiagnosis. Indeed, the study highlighted poor acceptability of telemedicine as first-line In a recent quality improvement study evaluating patients' satisfaction prior to endoscopy [10] , 138 patients underwent an advanced endoscopic pre-procedure consultation visits by three different modalities (telemedicine [26%], traditional in-person visits [21%], or a direct access procedure [52%]). The authors failed to demonstrate any statistically significant differences between these groups. However, patients with a de novo diagnosis of gastrointestinal cancer and attending a telemedicine visit had a greater satisfaction level in comparison to a direct access procedure. These results were consistent with the present study, where teleconsultation was considered appropriate for medical history collection, prehospitalization and interview preceding a conventional visit. Moreover, teleconsultation was not recommended for the diagnosis and management of diverticular disease, IBD, and oncological diseases, given the high risk of misdiagnosis. Conversely, it was recommended in the management of stoma patients, in line with the results of a previous randomized controlled trial [11] . The intervening period between two teleconsultations should be shorter than that between two conventional consultations, due to the fear of a misdiagnosis that might cause significant treatment delays. For the same reason, the panel considered teleconsultation appropriate for IBD, oncological and diverticular diseases only after performance of secondline imaging modalities, colonoscopy and dosage of fecal calprotectin. A recent survey including 374 cancer patients and 14 physicians pointed out that the majority of both patients (63.1%) and physicians (64.1%) preferred a complete inperson assessment, even if remote visits may prevent the risk of contagion [12] . Recently, Ruf et al. [13] showed the effectiveness of telehealth care through a combined setup of videoconferencing appointments attended by 88 IBD patients, with only 0.9% of visits requiring urgent medical evaluation and a non-attending rate of 2.6%. In particular, the authors demonstrated the time and cost-saving potential of telemedicine in remote/ rural areas. Further advantages were reported by Sellars et al. [14] , showing that video consultation saved 6.685 traveled miles, 148 h traveling time and £1767 cost as well as a carbon dioxide emission exceeding 250.000 charges of a smartphone. Interestingly, the panel strongly agreed on the potential of telemedicine to reduce distances between geographically distant areas. In line with previous recommendations [15] [16] [17] , telemedicine was felt strongly appropriate for multi-decisional team meetings. In particular, being the collaboration between specialists the cornerstone of cancer treatment, telemedicine can contribute overcoming some barriers that often limit its effectiveness (e.g., increased productivity, remote reporting, and reduced travel costs). Interestingly, agreement was not reached regarding the cost of a teleconsultation compared to an in-person assessment. In this context, none of the proposed statements were deemed appropriate. The lack of long-standing experience in telehealth care among the panelists may partly explain this finding. Our study has some limitations. The exact role of telemedicine in colorectal practice remains to be established. However, the agreed goal was to lay the foundation for understanding and preventing harm caused by its reckless use. Despite being selected upon their publication track record in the colorectal field, participants' overall experience with telemedicine was scarce at the time of consensus. Hence, judgments may have reflected a more skeptical view concerning the applicability of telemedicine to a specialty where objective examination is sacrosanct. The good balance of older and younger generations among panelists could have helped to mitigate the selection bias at the cost of low levels of agreement. The tragedy of the pandemic has prompted our recognition and understanding of telemedicine's importance. This e-consensus may support healthcare stakeholders in planning structural interventions for the future. It is advisable that all tertiary colorectal centers should have a teleconsultation system. Standardization of infrastructures and costs remain to be better elucidated.
