Introduction: Patients undergoing radical cystectomy with urinary diversions (UD) are at increased risk of bone fractures compared to the general population. Although a loss of bone mineral density (BMD) has been described in patients with UD, we still do not know with certainty why these patients follow this tendency., Objective: We performed a systematic review of the available literature to analyze the prevalence of osteoporosis and bone alterations in patients with ileal UD and the possible associated risk factors., Evidence Acquisition: We systematically searched PubMed® and Cochrane Library for original articles published before December 2022 according to PRISMA guidelines., Evidence Synthesis: A total of 394 publications were identified. We selected 12 studies that met the inclusion criteria with 496 patients included. Six of the twelve studies showed decreased BMD values. Prevalence of osteoporosis was specified in three articles, with values ranging ​​from 0% to 36%. Risk factors such as age, sex, body mass index, metabolic acidosis and renal function appear to have an impact on bone tissue reduction, while type of UD, follow-up, 25-hydroxyvitamin D and parathormone had less evidence or contradictory data. The heterogeneity of the studies analyzed could led to interpretation bias., Conclusions: UD are associated with multiple risk factors for osteoporosis and bone fractures. Identifying patients at highest risk and establishing diagnostic protocols in routine clinical practice are essential to reduce the risk of fractures and the resulting complications., (Copyright © 2023 AEU.

Introduction and Objective: Metabolic acidosis (MA) is a well-known complication in patients with ileal urinary diversions. It is common in the early postoperative stages and decreases over time. Our objective is to investigate the prevalence of MA after more than one year of follow-up, identify the associated risk factors, and analyze its secondary metabolic consequences., Materials and Methods: We conducted an observational study between January 2018 and September 2022 following the STROBE guidelines. MA was defined as a serum bicarbonate level ​​<22mEq/L. Finally, we analyzed 133 patients with a mean follow-up of 55.24 ± 42.36 months., Results: MA was observed in 16 (12%) patients. Patients with and without MA were comparable in age, sex, and follow-up time. The group with MA presented a higher rate of anemia (68,75% vs 19,65%, p < 0.001) and renal failure (100% vs 45,29%, p < 0.001), statistically significant higher levels of serum creatinine, chloride, potassium, parathyroid hormone, and phosphorus but lower serum values ​​of hemoglobin, renal glomerular filtration rate, total cholesterol, vitamin D, calcium, and albumin (all p < 0.05). Renal glomerular filtration rate was the only independent risk factor related to the development of MA (OR 0.914; 95% CI 0.878-0.95; p < 0.0001), proving a close correlation with venous bicarbonate values ​​(r = 0.387, p < 0.001)., Conclusions: MA is a little prevalent disorder in ileal urinary diversions more than one year after radical cystectomy is performed but it has secondary consequences on hematologic, renal, protein, lipid, and bone metabolism. We recommend to a close follow-up in patients with renal failure for early diagnosis and treatment., (Copyright © 2023 AEU. Published by Elsevier España, S.L.U. All rights reserved.)

Urine contact with the mucosa of the urinary diversion (UD) after radical cystectomy (RC) produces different ion exchanges that favor the development of metabolic acidosis (MA). This phenomenon is a frequent cause of hospital readmission and short/long-term complications. We performed a systematic review of MA in RCs with ileal UD, analyzing its prevalence, diagnosis, risk factors and treatment. We systematically searched Pubmed® and Cochrane Library for original articles published before May 2022 according to PRISMA guidelines. A total of 421 articles were identified. We selected 25 studies that met the inclusion criteria involving 5811 patients. Obtaining precise data on the prevalence of MA is difficult, largely due to the heterogeneity of the diagnostic criteria used given the diversity of studies analyzed. Development of MA is multifactorial. In the early period, MA is more prevalent in patients with UD with longer ileal segments, better urinary continence, and impaired renal function. Age and diabetes are risk factors associated with MA in later periods. MA is the most common cause of second or more hospital readmissions. Prophylaxis with oral bicarbonate for three months in patients at risk could improve these results. Although MA after ileal UD is a well-known condition, this review highlights the need to implement homogeneous criteria for the diagnosis, follow-up, and treatment, in addition to protocolizing prevention/prophylaxis strategies in patients at risk., (Copyright © 2022.

Introduction: The doctorate is the third cycle of official university studies, which, through the defense of the doctoral thesis leads to the acquisition of the title of doctor or PhD from the Anglo-Saxon countries. Royal Decree law 99/2011 regulates doctoral programs, with a wide margin on quality requirements. The objective of this study is to find out if there is this variation in the requirements of the doctorate programs of the different departments of surgery of the Spanish public universities and to establish a quality scale., Methods: Cross-sectional observational study from 2/22/2021 to 3/3/2021, through a survey sent electronically to the professors of the departments of surgery., Results: Thirty-five departments of surgery were consulted, obtaining a response in 29 of them (82.9%). The observed variation regarding requirements has been basically in the quality of the research project, in fact in 25 (86.2%) there are no regulations on this. When it is presented in the form of a compendium of articles, these are required to be original in 15 (51.7%). Regarding the position as author, the doctoral student must be the preferred author, at least in 2 articles in 14 (48.4%) of the programs. In 14 departments (48.4%) there are no regulations on the position of the articles and quartiles of journals. When scoring the different programs according to their requirements, the variability is high, ranging between 2 and 19 points. Funding for the development of the doctorate is meager., Conclusions: There is a wide variability in the requirement of doctoral programs. Homogeneous levels of demand must be defined to promote and protect higher-level doctorates., (Copyright © 2021 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.)

At present, in daily practice, the Departments of Surgery in most hospitals in Spain are organized into "Specialized Surgical Units", including specific structure, human resources, organization, teaching and research in the different subspecialties included in General and Digestive Surgery (GDS). Furthermore, there are also several specialized "fellowship-like", training programs in the different subspecialties already working in some of these "Specialized Surgical Units", although not officially financed. However, until now there was no model for accreditation or recognition of these Units or fellowship programs. The AEC has designed a regulation for the accreditation of Specialized Surgical Units in GDS, that will also serve as a model to define subspecialty training in these areas. The accreditation process, and with it, the process of quality improvement, includes different quality indicators, including unit structure, process quality, and result indicators., (Copyright © 2021 AEC.

Introduction: The Law for the Regulation of Health Professions (LOPS) indicates that health professionals will carry out continuous training throughout their professional life, and will regularly prove their professional competence. The objective of the study was to carry out a national survey to find out the opinion of Spanish surgeons and thus be able to prepare a recertification project by the Spanish Association of Surgeons (AEC)., Methods: Cross-sectional observational study carried out in June-July 2020, through a survey sent to the members of the AEC., Results: The survey had a total of 1230 visits and an overall completion rate of 784 responses (67.3%). 69.6% were unaware of the LOPS forecasts and 83.4% were unaware of similar initiatives in other specialties and 95.5% agreed to demand adequate information. 71.4% believed it necessary but only 57% believed that it should be mandatory. 82.9% would agree that it should be regulated through an objective and predictable official procedure., Conclusions: The concept of re-accreditation is not well known in our specialty and in view of the results obtained, adequate and reliable information seems necessary. Therefore, it would be pertinent to propose by the AEC a specific project to assess activities and skills., (Copyright © 2020 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.)

Purpose: Combined endoscopic and laparoscopic surgery (CELS) has emerged as a promising method for managing complex benign lesions that would otherwise require major colonic resection. The aim of this study was to describe the different techniques and to evaluate the safety of CELS, assess its outcomes in a technique that is scarcely widespread in our environment., Method: Observational retrospective study, short-term outcomes of patients undergoing CELS for benign colon polyps from October 2018 to June 2020 were evaluated. Postoperative outcomes, length of hospital stay and pathological findings were evaluated., Results: Seventeen consecutive patients underwent CELS during the study period. The median size of the lesion was 3.5 cm (range 2.5 - 6.5 cm), the most frequent location was the cecum (10 from 17). Most patients treated with CELS underwent an endoscopic-assisted laparoscopic wedge resection (11 from 17). In four patients this resection was combined with another CELS technique, and two patients underwent an endoscopic-assisted laparoscopic segment resection. The success rate of CELS in our series was in 14 from 17 (82,4%). The median operative time was 85 min (range 50-225 min). The median hospital stay was 2 days (range 1-15 days). One patient experienced an organ/space surgical site infection which did not require further intervention. Four lesions were shown to be malignant by postoperative pathology study., Conclusion: CELS is a safe and multidisciplinar technique that requires collaboration between gastroenterologists and surgeons. It can be considered as an alternative to colonic resection for complex benign colonic polyps., (Copyright © 2020 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction: A trimodal prehabilitation protocol was designed with the aim to evaluate whether it contributes to reducing postoperative morbidity, to evaluate the effect of prehabilitation on overall hospital stay, and to analyze the evolution of functional capacity before and after surgery., Methods: A single-center observational study of patients with colorectal cancer who underwent surgery with curative intent after a trimodal prehabilitation protocol. We collected data for postoperative morbidity according to the Comprehensive Complication Index and hospital stay, which were compared with a historical matrix. Functional capacity data were also collected before and after the application of the prehabilitation protocol., Results: Compared to the historical population, the overall Comprehensive Complication Index was reduced from 13.2 to 11.5, which was statistically significant. Analyzed by morbidity type, all decreased in percentage, although without achieving significance (surgical site infection from 11.7% to 8.4%, nosocomial infection 15.8 to 10% and medical morbidity 8.6% to 4.2%). The overall hospital stay went from 6 to 4 days, and the decrease in the percentage of patients who prepared at home was statistically significant in both cases., Conclusions: Trimodal prehabilitation can contribute to lowering the postoperative morbidity and overall hospital stay of patients undergoing colorectal cancer surgery., (Copyright © 2020 AEC.

Introduction: Physicians, especially surgeons, are significatively affected by burnout. Duty-hour violation, as well as discrimination, abuse and sexual harassment may contribute to burnout. A study about this topic has been published in residents from United States, demonstrating a high incidence of burnout. Our objective is to know which is the situation in Spain and to compare it with United States., Methods: Cross-sectional observational study carried out in January-February 2020, based on the responses to a validated survey administered to General Surgery residents in Spain., Results: There are 931 General Surgery Residents. 739 have entered in the survey and 452 (61.2%) eventually responded to it. In any occasion during the training period, 55.1% reported discrimination based on their gender, 8.8% reported racial discrimination, 73.9% reported verbal/psychological abuse, 7.1% reported physical abuse and 16.4% reported sexual harassment. Attending surgeons are the most frequent source of sexual harassment and physical and verbal abuse, whereas patients are the most frequent cause of gender discrimination. Burnout symptoms were reported by 47.6% of residents and 4.6% reported suicidal thoughts. 98% of residents reported duty-hour violations and 47% of them do not have the day off after to be on call. Both of these issues are burnout predictive factors., Conclusions: Mistreatment (discrimination, abuse and harassment) occurs among General Surgery residents during their training period in our country. Every kind of mistreatment is more frequent in Spain than in the United States, with the exception of racial discrimination. It is associated with exceeding weekly duty-hour. It is necessary to know these problems and to avoid them in order to improve work environment of General Surgery training period., (Copyright © 2020 AEC. Publicado por Elsevier España, S.L.U.

Introduction: Frailty is associated with greater postoperative morbidity and mortality. Individualized multidisciplinary management of these patients can improve the quality of care. The objectives of this study are to determine the percentage of frail patients with colorectal cancer in our population, and to describe the morbidity and mortality associated with surgery and the evolution of palliative treatment., Methods: A prospective, observational study of patients with surgical colorectal cancer (February 1, 2018-April 30, 2019). Frail patients were screened and classified according to degrees of frailty. Therapeutic decision-making (surgery or palliative treatment) was determined by the degree of fragility and explicit will of the patient. Postoperative comorbidities were analyzed (according to Clavien-Dindo and Comprehensive Complication Index), as were mortality and oncological follow-up., Results: The study included 193 patients with surgical colorectal cancer, with a mean age of 74 years (44-92). Screening identified 46 frail patients (24%), with a mean age of 80 years (57-92). Twenty-two patients were optimized and underwent surgery (48%), with a mean age of 78 years (57-89). Relevant adverse effect rate was 27.7% (4 grade iva adverse effects, one ivb and one v, according to Clavien-Dindo). Comprehensive Complication Index was 17.5. Palliative treatment was administered in 24 patients (52%), with a mean age of 82 years (59-92). Mean follow-up was 7.8 months. There were 2 deaths due to disease progression (8.3%), 5 re-consultations due to complications of colorectal cancer (20.1%)., Conclusions: The multidisciplinary and individualized management of frail patients with colorectal cancer is key to improve the quality of care in the treatment of this patient group., (Copyright © 2020 AEC.

Our main goal is to describe how to start and develop a multicenter, prospective, randomized, controlled trial. The first step is to have an idea that will become the hypothesis and a main objective. A bibliographic search should be done to check for clinical interest and originality. Moreover, the study must be feasible and should be finished within 4 years. In order to start the multicenter study, a protocol should be written (in accordance with the SPIRIT guidelines Standard Protocol items: Recommendations for Interventional Trials), including the design type, sample size and participating hospitals. Randomization is key to the design and, therefore, the CONSORT (Consolidated Standards of Reporting Trials) guidelines must be followed. However, if the study cannot be randomized, the TREND (Transparent Reporting of Evaluations with Non-Randomized Designs) guidelines are recommended. When the protocol is approved by the Ethics Committee for Clinical Investigation of the hospital, we ought to create visibility. It is suggested to register the trial on ClincalTrials.gov and submit its publication to indexed magazines. Financial resources are necessary to execute the study and maintain an online database. This allows the registry to be updated and accessible to all the participants in the study. What is more, randomization can be done immediately. And last, but not least, is motivation. Multicentricity equals to participation of all the chosen medical centers. Updating and motivating them by sending a newsletter every 1-3 months keeps participants engaged in the study., (Copyright © 2019 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.)

Objective: This study determines the quality of life and the anorectal function of these patients., Method: Observational study of two cohorts comparing patients undergoing rectal tumor surgery using TaETM or conventional ETM after a minimum of six months of intestinal transit reconstruction. EORTC-30, EORTC-29 quality of life questionnaires and the anorectal function assessment questionnaire (LARS score) are applied. General variables are also collected., Results: 31 patients between 2011 and 2014: 15 ETM group and 16 TaETM. We do not find statistically significant differences in quality of life questionnaires or in anorectal function. Statistically significant general variables: longer surgical time in the TaETM group. Nosocomial infection and minor suture failure in the TaETM group., Conclusion: The performance of TaETM achieves the same results in terms of quality of life and anorectal function as conventional ETM., (Copyright: © 2018 Permanyer.)

Introduction: The association of preoperative chemoradiotherapy and transanal endoscopic surgery in T2 and superficial T3 rectal cancers presents promising results in selected patients. The main objective is to evaluate the long-term loco-regional and systemic recurrence and, as secondary objectives, to provide results of postoperative morbidity and the correlation between complete clinical and pathological response., Methods: This is a retrospective observational study including a consecutive series of patients with T2-T3 superficial rectal cancer, N0, M0 who refused radical surgery (2008-2016). The treatment consisted of preoperative chemotherapy (5-fluorouracil or capecitabine) combined with radiotherapy (50, 4Gy) and transanal endoscopic surgery after 8weeks. Preoperative, surgical, pathological and long-term oncologic results were analyzed., Results: Twenty-four patients were included in the study. Two of them required rescue radical surgery for unfavorable pathological results. A local recurrence (4.5%) was observed and 2patients presented systemic recurrence (9%), with a median follow-up of 45 months. A complete clinical tumor response was achieved in 12 patients (50%), and complete pathological tumor response in 9 patients (37.5%). Postoperative complications were observed in 5 patients (20.8%), and they were mild except one. There was no postoperative mortality., Conclusions: In this stage of rectal cancer, our results seem to support this strategy, mainly when a complete pathological response is achieved. The complete clinical tumor response does not coincide with the pathological tumor response. Randomized prospective studies should be performed to standardize this treatment., (Copyright © 2017 AEC.

Introduction: The surgical electronic logbook (surgical e-logbook) aims to: simplify registration of the training activities of surgical residents, and to obtain reliable and detailed reports about these activities for resident evaluation., Methods: The surgical e-logbook is a unique and shared database. Residents prospectively record their activities in 3 areas: surgical, scientific and teaching. We can access activity reports that are constantly updated., Results: Study period using the surgical e-logbook: Between June 2011 and May 2013. Number of surgeries reported: 4,255. Number of surgical procedures reported: 11,907. Number of surgeries per resident per year reported: 250. Number of surgical procedures per resident per year reported: 700. Surgical activity as a primary surgeon during the first year of residency is primarily in emergency surgery (68,01%) and by laparotomy (97,73%), while during the fifth year of residency 51,27% is performed in elective surgery and laparoscopy is used in 23,10% of cases. During this period, residents participated in a total of 11 scientific publications, 75 conference presentations and 69 continuing education activities., Conclusions: The surgical e-logbook is a useful tool that simplifies the recording and analysis of data about surgical and scientific activities of the residents. It is a step forward in the evaluation of the training of surgical residents, however, is only an intermediate step towards the development of a larger Spanish registry., (Copyright © 2014 AEC.

The royal decree RD 639/2014 has been published, regulating among others, the core curriculum, and specific areas of training (SAT). It is of great interest for the specialty of General and Digestive Surgery (GS and DS). The aim is to expose and clarify the main provisions and reflect on their implications for the practical application of the core curriculum and SAT in the specialty of General and Digestive Surgery, to promote initiatives and regulations. This RD will be a milestone in our specialty that will test the strength of the specialty, if it does not finally culminate in its degradation against the emergence of new surgical specialties. A new stage begins in which the Spanish Association of Surgeons should be involved to define the conceptual basis of GS and DS in the XXI century, and the creation of new SAT to continue to maintain the "essence of our specialty"., (Copyright © 2014 AEC.

Background: Adhesions are the most important cause of intestinal obstruction. Approximately 25% of surgical admissions for acute abdominal conditions are due to intestinal obstruction. Better diagnostic and treatment methods of intestinal obstruction could potentially reduce mortality rate to 5-10%. Gastrografin(®) could contribute to this achieve this., Aim: To present a protocol to treat adhesion intestinal obstruction with Gastrografin(®) that is safe, and allows shorter hospital stays and shorter time between admission and surgery., Material and Methods: All patients with adhesion intestinal obstruction without symptoms of strangulation were treated with Gastrografin(®), intravenous fluids and nasogastric tube. Those in whom contrast reach the colon in 8, 12 or 24hours were considered to have partial obstruction, and were fed orally. If Gastrografin(®) failed in the following 24hours, a laparotomy was performed., Results: Out of a total of 211 episodes (164 patients), 170 episodes received contrast and in 142 cases Gastrografin(®) reached the colon (104 episodes at 8h, 11 at 12h, and 27 at 24h). A laparotomy was required in 28 patients because of failed treatment, and in another 5 for other causes., Conclusions: A management protocol for adhesion intestinal obstruction with Gastrografin(®) is safe, reduces morbidity and mortality, and leads to a shorter hospital stay., (Copyright © 2012 AEC.

The training of residents in abdominal wall surgery is a fundamental aspect of surgical training, representing globally 20% of its activity. In this paper, we analyze the current state of resident training in this kind of surgery in Spain, taking into account the broad spectrum it covers: general services, specific functional units, ambulatory surgery programs. To do this, based on the specifications of the specialty program, specific data were used from several different sources of direct information and a review of the results obtained by residents in hernia surgery. In general, our residents agree with their training and the recorded results are in line with objectives outlined in the program. However, it would be important to structure their teaching schedules, a rotation period in any specific unit and their involvement in outpatient surgery programs., (Copyright © 2011 AEC.

Rectal prolapse repair techniques using laparoscopic abdominal surgery are the treatments of choice. However, in patients with increased morbidity, perineal surgical techniques are indicated. Transanal endoscopic surgery is presented as a possible alternative option in groups with increased experience in it., (Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.)

Introduction: There are no quantified data on the real activity carried out by residents during the 5 years of training in the specialty of general and digestive surgery (GGS) in Spain. There are also limited data on programs in other surgical specialities, and in other countries. The aim of the study is to estimate the mean overall surgical activity by specific skill areas and by the level of complexity of the Spanish program in the specialty of GGS., Patients and Method: A prospective, observational, multicentre study was performed on the activity of GGS residents in Spain using the Resident Computerised Logbook of the Spanish Surgeons Association (LIR-AEC). Each of the residents registered their own activity supervised by their tutor. The sample period was 6 months. The medians of the annual activity and the period of residency were calculated from the results., Results: Surgical activity: during the residency, it was estimated that that they attended 1,325 operations, 654 (49%) as lead surgeon. Health care activity: the mean number of times on-call was 5.2±1.8 per month. Activity in outpatient clinics was 548 first visits, and almost double for second visits. Scientific activity: the total number of courses and conferences attended was 34. The estimated mean number of presentations at conferences was 14, with 3 publications., Conclusions: LIR-AEC is a suitable tool to verify activity in the Spanish GGS Program. These results may be useful for comparing with training programs in other countries and in other surgical specialties., (Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.)

Introduction: The introduction of the Spanish Association of Surgeons resident's electronic book (AEC-E-Book), has meant that we can perform particular and overall assessments of each resident. The objective of this article has been to find out the mean health care, scientific and surgical activities according to the speciality program., Material and Method: A register of the activities of residents in the AEC-E-Book. The overall activity per year and per rotation has been measured. The relationships of assisted interventions performed and their level of complexity have been analysed. The mean scientific and health care activities and the mean on-call periods per month., Results: A total of 8 residents have registered their activity in the AEC-E-Book since the year 2004. They assisted in a mean of 1514 operations, of which 922 were performed as surgeon (62%). They assisted in 185 laparoscopic interventions, of which they performed 72 (39%). As surgeon, 864 (94%) of the 922 procedures 64% were level 1, 75% level 2, and 53% were level 3. They were on-call a mean of 5.75 times per month. They attended a total of 21 courses and congresses during residency. They took part in 24 presentations and posters, as well as in 6 journal publications during residence., Conclusions: The AEC-E-Book enables the activity of the resident to be continually assessed. We have been able to find out the mean activities carried out by each resident during a particular rotation and year, thus being able to know exactly if they have fulfilled the defined minimums.

Introduction: The local exeresis adenocarcinoma of the rectum T(2)N(0)M(0) (ADC-T2), using transanal endoscopic microsurgery (TEM), has the benefit of achieving lower morbidity with a better quality of life. However, local occurrence of the local exeresis is greater than 20%, which is unacceptable these days., Patients and Methods: Prospective, observational follow up study. The tumours committee agreed that those ADC-T2 patients could have the following treatments: total mesorectal excision (TME), simple TEM, TEM with postoperative chemo- and radiotherapy (Ct-Rt), preoperative Ct-Rt with subsequent TEM and radical surgical rescue (TME) within at least 4 weeks., Results: Of the 146 patients operated on using TEM, 75 had adenocarcinomas, 59 adenomas, 6 scarring wounds, 5 carcinoids and 1 GIST. Of the adenocarcinomas 22 were ADC-T2. Follow up: median of 16 months (range, 3-32 months). The overall local recurrence was 18% (4/22). According to the treatment strategy the local occurrence was: TEM as the only procedure, 20% (2/10). Radical surgical rescue was performed on 3 patients after TEM, with no local or systemic recurrences. TEM with Qt-Rt after surgery was performed on 6 patients, with a local recurrence of 33% (2/6). Ct-Rt and subsequent TEM in 3 patients, with no local or systemic recurrences., Conclusions: Treatment of ADC-T2 using simple TEM is not effective. The combination of Ct-Rt after TEM, does not improve the results of TME. It is possible to rescue those patients without changing the overall survival. Preoperative Ct-Rt and TEM appears to be the approach that obtains a clinical and histological response, although a response is needed by clinical trials.

Introduction: Mechanical preparation of the colon (MPC) in colorectal surgery has been a dogma that has been questioned over the last few years. The objective of this study is to demonstrate that morbidity in scheduled colorectal surgery is the same or lower without MPC., Material and Method: Patients subjected to scheduled left colon and rectal surgery with primary anastomosis randomised into two groups. The "Preparation" group (MPC) received MPC and the "non-preparation" group (No-MPC) had only cleaning enemas. The variables collected were: demographic, oncological, nutritional, risk prediction models and morbidity-mortality., Results: Of the 193 patients included: 69 received MPC and 71 did not; 89 patients with colocolic anastomosis (MPC, 38; no MPC, 51) and 50 colorectal (MPC, 31; no MPC, 19). Statistically significant differences were seen in the overall analysis in favour of "no preparation" as regards morbidity (43.55 % with MPC and 27% with No MPC) and nosocomial infection (27.5% and 11.4%). There was 11.6% wound infections in the MPC compared to 5.7% in the no MPC, which was not statistically significant. The only mortalities were in the MPC group 2/69 (2.9% of patients). As regards the location of the anastomosis, in the colocolics the differences were more pronounced, with statistically significant differences in the morbidity, anastomosis dehiscence, and nosocomial infection variables. The effect of no MPC was not so evident in colorectal anastomosis., Conclusions: Our results suggest that there is no benefit in MPC before surgery in colocolic anastomosis. No-MPC is not associated with a higher morbidity in wound infection or anastomotic dehiscence. In colorectal anastomosis the differences are not so evident, therefore a much bigger series needs to be studied.

On 8 may 2007, the Official Bulletin (BOE) published the new Specialist Training Program. The Post-Graduate Training Section of the Spanish Surgeons Association (AEC), conscious of the importance of this situation, has carried out a reflective analysis of this Program and proposes a series of objectives. The new plan coordinates a training program that sets out three general objectives as regards, knowledge, skills and attitudes that the resident must assimilate and develop, it strictly defines the final product, without substantially changing the previous program and emphasises two fundamental aspects: training in minimally invasive surgery and research training, although the inclusion of previously unpublished new rotations and the continuation of the current assessment model. The logic in the definition of general surgery as "a major discipline paradigm" should lead to important structural changes. Aspects such as regulating work and training times, European Directives, lack of professional motivation and changes in the vocational spectrum of new residents, will make the optimisation of the results difficult a priori. The year 2017 will be the time to judge the results after five groups of surgeon graduates have been trained by this program.

Transanal endoscopic microsurgery (TEM) uses specific equipment that allows resection of large rectal adenomas and incipient malignancies in the rectal ampulla. TEM aims to provide an alternative to conventional abdominal surgery (low anterior resection or abdominoperineal amputations), which carries not inconsiderable morbidity and mortality. Application of the technique of endoanal excision is limited by the height and extension of the lesions. In this review, the authors present their own experience with this technique and that described in the literature. The protocol for selecting candidates for TEM, their preoperative preparation, equipment, characteristics of the surgical technique, postoperative complications, and follow-up are described. The collaboration of a multidisciplinary team is essential when developing this technique. TEM-associated morbidity is low and mortality is practically nil. TEM is the technique of choice in large rectal adenomas and malignant rectal tumors in stages pT1 localized in the rectal ampulla. The frequency of recurrence is similar to that in abdominal surgery. The technique does not cause complications of urinary or sexual dysfunction and fecal incontinence is minimal. In more advances stages of rectal cancer, the results of better patient selection and future studies on the possible application of neoadjuvant therapy associated with TEM are required.

Introduction: Because of the developments that have occurred in surgery in the last few years, updates are required not only in the content of resident physicians' training but also in evaluation of the knowledge acquired. The present article aims to present our experience of an integral evaluation model. This model is based on evaluation of theoretical knowledge and surgical skills., Material and Method: The training program for resident physicians (medico interno residente [MIR]) has four main branches: clinical work, continuing training, research (doctorate) and evaluation of the activity performed (computerized activity record). This record allows the theoretical knowledge and skills acquired to be evaluated at the end of each rotation. Through 6-monthly evaluations, each resident's activity can be quantified over time and compared with that of other residents., Results: The system was introduced in July 2004. Each resident was given his or her own database. All the activities performed were then introduced into the database. The results of overall activity and that of each resident are presented., Conclusions: The method used allows residents' integral progress to be followed-up and a completely objective evaluation to be made at the end of each year and at the end of the residency period. Widespread use of this system, or a similar system, would enable comparisons with other centers to be made under similar premises. This system could also help to unify criteria and identify deviations in training.
