Endoscopic retrograde cholangiopancreatography (ERCP) performed in situations of altered anatomy has been described. Thus, in cases of Roux-en-Y gastric by-pass, several approaches have been documented for performing ERCP: by enteroscopy, guided by laparoscopic approach through the gastric remnant, and direct transgastric guided by endoscopic ultrasound through a stent between the reservoir or alimentary loop and the gastric remnant. However, there are clinical situations in which the anatomy is not altered, but there may be pancreatic lesions subsidiary to study by endoscopic ultrasound in situations where the endoscope cannot pass through the esophagus. Therefore, we present the clinical case of a patient with a pancreatic lesion subsidiary to study and a distal esophageal adenocarcinoma that prevented the passage of the endoscope.
RESUMO
The relationship of proton pump inhibitors (PPIs) with gastric cancer is not clear. However, more and more patients with gastroesophageal reflux disease (GERD) who are candidates for therapy with PPIs reject such treatment. This situation is largely caused by global access to information, especially on the internet, where some news has recently been published linking PPIs to the development of gastric cancer. For this reason, patients with GERD who are candidates for therapy with PPIs, before rejecting such treatment and opting for antireflux surgery, should be aware of the morbidity and mortality of the surgery and the current scientific evidence regarding the relationship between PPIs and gastric cancer.
RESUMO
We present the third case described to date of large cell neuroendocrine carcinoma located at the esophagogastric junction (LCNEC). Esophageal neuroendocrine tumours account for 0.03-0.05% of all malignant esophageal tumours. Within oesophageal NETs, LCNEC accounts for 1% of esophageal NETs. This tumour type is characterised by elevated levels of certain markers: synaptophysin, chromogranin A and CD56. In fact, 100% of patients will have chromogranin or synaptophysin, or at least one of these three markers. In turn, 78% will have lymphovascular invasion and 26% will have perineural invasion. Only 11% of patients will have stage I-II, which implies an aggressive course and worse prognosis.

Lymphoepithelioma-like gastric adenocarcinoma is characterised by a large reactive lymphoplasmacytic infiltrate in the stroma and islets of undifferentiated cells, which express intense and widespread Epstein-Barr virus (EBV). This tumour type has higher survival rates than other gastric cancers, a more proximal location and less lymphatic spread. Our aim is to describe the clinical and pathological characteristics of our series of lymphoepithelioma-like gastric adenocarcinoma. We selected patients who underwent surgery for gastric adenocarcinoma lymphoepithelioma-like variant from 2014 onwards. The results of the following variables were collected: age (years), sex, pre-diagnostic clinical time (months), gastric tumour location, endoscopic biopsy histology, surgical technique, in situ hybridisation for EBER region (Epstein-Barr virus-associated non-coding RNA), microsatellite instability, degree of differentiation, level of resection, tumour size (cm), TNM T value, lymphadenopathy/resected node ratio, overall survival (months) and vital status. Our experience in the lymphoepithelioma-like variant presents as an advanced gastric cancer, possibly related to long-standing prediagnostic symptoms. It behaves as a tumour with expansive local growth with little capacity for lymphatic or metastatic involvement, which could be explained by the prominent intratumoral lymphoid stroma that acts as an antimetastatic barrier.
RESUMO
Gastric schwannoma can be malignant in 13.8% of cases. The prognosis of malignant schwannoma is usually poor, characterized by a rapidly progressive disease course and a poor response to chemotherapy. Normally, the recurrence of schwannoma is due to involvement of the surgical resection margin. In turn, recurrence of malignant gastric schwannoma GS is approximately 50%, 25% locoregional and 25% with liver metastases. Even after a complete gastric resection with associated lymphadenectomy, schwannoma may present liver metastases during follow-up.

Streptococcus constellatus is a Gram-positive commensal bacterium of the oropharyngeal, gastrointestinal and urogenital flora. It can cause abscesses in different parts of the body, especially in immunocompromised patients. We present the clinical case of a 33-year-old female patient with a previous history of one anastomosis gastric bypass, among others. The patient was hospitalized two years after surgery for peritonitis secondary to a perforation in the biliopancreatic loop, underwent laparoscopic surgery and was hospitalised for two weeks. Fifteen days after being discharged from the hospital, she went to the emergency service for abdominal pain and fever. An abdominal and pelvic computerized tomography (CT) scan showed a multiloculated pelvic collection with thickened and hypercapillary walls.

Although morphology is the key to histological diagnosis, gastric mesenchymal tumors can share very similar growth and cellularity patterns, sometimes being indistinguishable. Therefore, immunohistochemical techniques are going to be crucial in the definitive diagnosis. The objective of this work is to perform an immunohistochemical differential diagnosis of gastric mesenchymal tumors.

Gastric neuroendocrine tumors (GNETs) account for less than 2% of gastric neoplasms and type 1 GNETs (GNETs-1), which are associated with chronic atrophic gastritis, account for 70-80% of all GNETs. Treatment of GNETs-1 is usually endoscopic, but surgery also has its indications. The aim of this study is to present five case reports of GNETs-1 treated with surgery and to analyze the surgical indications for this type of tumors.
RESUMO
We report the case of a 65-year-old male with hypertension, diabetes and hypercholesterolemia, who presented due to pyrosis and regurgitation. A CT scan incidentally identified esophageal compression at two sites because of vascular abnormalities, which was asymptomatic. The proximal compression was due to a Kommerell's diverticulum (Fig. 1) and the distal one due to aortic tortuosity (Fig. 2). Esophageal manometry revealed a distal obstructive pattern of mechanical origin, which was consistent with the observed aortic kink. The esophagogram (Fig. 3) showed a proximal filling defect and a bend in the distal third.

INTRODUCTION: Bariatric surgery improves sexual function in obese individuals, although the extent to which sexual satisfaction is improved following surgery is unknown. The aims of this study were 1) to describe sexual satisfaction in severely/morbidly obese men and women candidates for bariatric surgery; 2) to assess the effects of bariatric surgery on sexual satisfaction at 12-months follow-up; and 3) to assess whether weight changes at follow-up following bariatric surgery are associated with changes in sexual satisfaction. METHODS: We conducted a prospective observational study from February 2011 to June 2014. A total of 44 patients with severe/morbid obesity participated in the study. Sexual satisfaction was assessed (at baseline and 12-months follow-up) through the Index of Sexual Satisfaction (ISS) questionnaire. RESULTS: Of 44 patients who completed the ISS at baseline (mean age 40.3 [SD=9.4] years and BMI 46.9 [SD=6.2] kg/m2), 17 were lost to follow-up. The baseline ISS total scores were 32.0 (SD=20.1) in women and 24.4 (SD=16.0) in men (P>0.05). The proportion of sexually satisfied men and women at baseline was 62.5% and 46.4%, respectively (P=0.360). At follow-up, sexual satisfaction improved significantly in women (average difference 13.7 units; P=0.032) but not in men (average difference 3.6 units; P=0.717). The percentage of women with sexual satisfaction problems was reduced by 33% at follow-up (P=0.038). CONCLUSIONS: A relatively large percentage of severely/morbidly obese women and men present clinically significant sexual satisfaction problems before undergoing bariatric surgery. Sexual satisfaction improves significantly 12 months following bariatric surgery, particularly in women.

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.

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.

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.

Adenocarcinoma (ADC) of the anal canal is a rare disease comprising only 5% of all anorectal neoplasias and 1.5% of all gastrointestinal tumours. The World Health Organisation classifies anal ADC into 3 types: the first may arise from the mucosa of the transitional zone in the upper canal, the second from the anal glands (ducts) and the last can develop in the environment of a chronic anorectal fistula. Patients with ADC of the anal canal have high rates of pelvic failure, distant metastasis, and lower overall survival than patients with epidermoid carcinoma. Because of limited case reports about this neoplasia, management strategies have not been well established. Most authors of related studies recommend preoperative chemoradiotherapy (CRT) followed by radical surgery. The aim of the present study is to review clinicopathology features and management of anal canal ADC.

OBJECTIVE: The aim of this study was to evaluate short-term outcomes of performing intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy for right colon neoplasm. BACKGROUND: Despite advances in the laparoscopic approach in colorectal surgery and the clear benefit of this approach over open surgery, because of the technical difficulty in performing intracorporeal anastomosis (IA), some continue to perform it extracorporeally in right colon surgery. MATERIALS AND METHODS: This study was a prospective multicenter randomized trial with 2 parallel groups on which either IA or extracorporeal anastomosis was performed in laparoscopic right hemicolectomy for right colon neoplasm, carried out between January 2016 and December 2018. RESULTS: A total of 168 patients were randomized during the study period. At baseline, the 2 groups were comparable for age, sex, body mass index, surgical risk, and comorbidity. The median length of postoperative hospital stay was 7 days with no differences between the groups. About 70% of patients had an uneventful postoperative period without complications. The most common complications were paralytic ileus (20.63%; 33), surgical site infection (SSI) (10%; 16), and anastomotic leakage (6.25%; 10). The results show a lower level of SSI in the IA group (3.65% vs. 16.67%, P=0.008). Other complications do not show statistically significant differences between groups. Likewise, the incision for the extraction of the specimen was smaller in the IA group (P=0.000) and creation of the anastomosis intracorporeally decreased postoperative pain (P=0.000). CONCLUSIONS: In comparison to the extracorporeal technique, IA decreased postoperative pain, incision size, and SSI. Further studies will be needed to verify our findings.
