Introduction: Transanal endoscopic microsurgery (TEM) was developed as a less aggressive alternative treatment for rectal lesions (mainly adenomas and adenocarcinomas). However, its use for other rectal lesions has become more frequent, trying to reduce the morbidity associated with more invasive techniques. The aim of this study is to describe our experience in the use of TEM in other rectal lesions., Methods: Retrospective and descriptive study including patients operated with TEM (from June 2008 to December 2016) for the treatment of rectal lesions different from adenomas or adenocarcinomas., Results: Among the 138 patients treated by TEM in our department, 10 patients were operated on for rectal lesions other than adenomas or adenocarcinomas. Rectal lesions were 3neuroendocrine tumours, a neuroendocrine tumour metastasis, a rectal stenosis, a cloacogenic polyp, an endometrioma, a retrorrectal tumour, a presacral abscess and a lesion in the rectovaginal septum. Mean operative time was 72min and postoperative stay was 4.2 days. Only one patient needed a reoperation, due to rectal bleeding., Conclusions: TEM could be a useful tool for the treatment of rectal lesions different from adenomas or adenocarcinomas, potentially decreasing the morbidity associated with more aggressive surgical techniques., (Copyright © 2017 AEC.

The appearance of new barbed sutures is an advance in making knots and anastomosis, mainly in laparoscopic surgery, where the majority of the surgeons find themselves limited dealing with these sutures. Through this review we aim to evaluate both the use and the safety of the sutures in General and Laparoscopic Surgery. Barbed sutures seem to ease the procedures improving key aspects such as reproducibility and operative time., (Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction: Clinical evidence has a more significant role in medical specialties than in surgery. Rectal cancer (CR) is no exception. This paper explores what CR-related subjects are being investigated at the present time in a quantitative and qualitative way and analyzes this information to know what possible answers clinical research could give us in the future., Methods: The data collection was carried out in April 2014 and was based on 3 sources: 2 institutional clinical trials registries -American (clinicaltrials.gov) and European (EU Clinical Trials Register)- and a survey given to members of the Asociación Española de Coloproctología (AECP). The obtained studies were exported to a database designed especially for this review, which included a number of descriptive elements that would allow the cataloging of the different studies. The AECP survey results were analyzed separately., Results: There are currently 216 clinical trials ongoing related to CR. Two-thirds are primarily conducted by oncologists. Nearly a third are surgical. The research focuses on improving preoperative treatment: new drugs, new schemes of chemo-radiotherapy (usually induction or consolidation schemes) or optimization of radiotherapy and its effects. Surgical clinical trials are related to robotics, laparoscopy, stoma, low colorectal anastomosis, distal CR and local treatment., Conclusion: Most of the current clinical trials ongoing on CR are analyzing aspects of chemo-radiotherapy and its effects. A third focus on purely surgical issues., (Copyright © 2014 AEC. Published by Elsevier Espana. All rights reserved.)

Numerous articles and opinions have been published in the last few years on how the Internet is changing clinical practice. In this article we focus on describing 2 aspects that we believe are fundamental in the web 2.0 and Medicine-Surgery inter-relationship: a) web 2.0 conceptualisation and its differences with other pre-existing tools, and b) a description of some of the tools that from a medical-surgical view could be of major interest to the professionals, the patients, and interaction between both. The time has arrived to board train 2.0, where the channels of communication between the professionals, and between them and the patients, are improving disease situations daily, to improve learning through contact with other physicians and surgeons, at the same time providing an excellent resource for maintaining health and to know the disease and its treatment., (Copyright © 2012 AEC.

Introduction: The abdominal approach for the treatment of rectal tumours is associated with considerable morbidity. Transanal endoscopic microsurgery (TEM) is a technical alternative, and less invasive than radical surgery, and thus, with a lower associated morbidity. Also, with the correct selection of patients, TEM shows similar oncological results to radical surgery. The objective of this study is to review our results with TEM and discuss its indications in the treatment of rectal tumours., Patients and Method: An observational, retrospective study with prospective collection of data conducted from June 2008 to January 2011. TEM indications were: benign rectal tumours non-resectable using colonoscopy; early malignant rectal tumours (T(1)N(0)M(0)) with good prognostic factors: neoplastic tumours in more advanced stages in selected patients (high surgical risk, refused radical surgery or stoma and palliative care)., Results: A resection was performed using TEM on 52 patients (35 benign and 17 malignant tumours). The mean hospital stay was 4.9 days, with an associated morbidity of 15.3%. The R(0) resection in adenomas and carcinomas was 97.1% and 88.8% respectively. During a follow-up of 15 (3-31) months, one recurrence of an adenoma was observed which was re-operated on using TEM., Conclusions: TEM is a safe and effective procedure for the treatment of benign and selected early malignant rectal tumours, and is associated with a low morbidity. However, it is a therapeutic strategy based on a multidisciplinary team, basically with careful selection of patients, a validated technique and a strict follow-up protocol., (Copyright © 2011 AEC.

Hereditary nonpolyposis colorectal cancer or Lynch Syndrome, caused by germinal mutations in mismatch deoxyribonucleic acid (DNA) repair genes, is the most common form of hereditary colorectal cancer. The identification of these individuals is not easy and is based on clinical and molecular criteria. A review is presented on the genetics and diagnosis in Lynch Syndrome, as well as on its surgical management and prevention., (Copyright © 2010 AEC. Published by Elsevier Espana.

Introduction: Minimally invasive surgical techniques have extended to all the fields of surgery. Breast surgery can also benefit from these concepts because of their special characteristics, reduction of aggressiveness, avoiding or hiding scars. The aim of our work is to introduce a new surgical approach for the resection of a large volume of breast parenchyma, including complete subcutaneous mastectomy and reconstruction using a pure muscular latissimus dorsi flap, with or without prosthetic material, through a minimal cutaneous incision., Patients and Method: Retrospective analysis of our series of 5 cases using our surgical technique which allows us to establish proper indications. We analyse the technical details, complications and results., Results: Five patients were operated using this technique (1 giant hamartoma, 1 multicentred in situ carcinoma with Paget's disease, 1 multicentred infiltrating carcinoma and 2 malignant tumours arising in the external part of the breast). We performed oncological resections (2 partial resections and 3 complete subcutaneous mastectomies) including sentinel lymph node biopsy or total axillary lymphadenectomy. After a mean follow-up of 10 months no local relapses were found and the cosmetic results were excellent., Conclusions: Minimally invasive surgical techniques through a posterior axillary line vertical incision enable total or partial subcutaneous mastectomy and a breast reconstruction, using muscular flaps or prosthetic material, to be performed.

Esophageal duplication cyst is a rare congenital alteration. Most of these cysts are asymptomatic and are usually identified as an incidental finding. These lesions can develop complications (bleeding, infection, etc.) and even malignant degeneration. Consequently, the treatment of choice is surgical.

We present the case of a woman who underwent surgery for an ileal carcinoid tumor and who subsequently presented breast metastases. The rarity of this case is discussed and a literature review is presented.
