Endoscopic ultrasound performed by surgical approach in a patient with pancreatic lesion and stenosing esophageal adenocarcinoma.

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.

Pilot study: a detailed analysis of the timing of immuno-inflammatory indices in gastric cancer, and their assessment together with TNM as supplementary prognostic factors.

An analysis of the prognostic impact of up to 36 immuno-inflammatory indices at 3 different times during the diagnostic-therapeutic process for gastric cancer. The dependent variable was disease-free survival at 3 years. The independent factors obtained were combined with TNM to provide an improved prognostic model.

Proton pump inhibitors (PPIs) and cancer. What should patients with gastroesophageal reflux disease candidates for PPIs therapy who refuse to comply with treatment know?

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.

Lymphoepithelioma-like gastric adenocarcinoma. Descriptive case series.

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.

Surgical indication of type I gastric neuroendocrine 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.

Physical Therapy in Tension-Type Headache: A Systematic Review of Randomized Controlled Trials.

(1) Objective: The aim of this study is to synthesize the effects of physical therapy on pain, frequency, or duration management in the short, medium, and long term in adult patients diagnosed with Tension-type headache (TTH). (2) Background: Tension-type headache (TTH) is the most common headache with migraine and its pathophysiology and treatment has been discussed for years without reaching a consensus. (3) Methods: A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The review was registered in PROSPERO (CRD42020175020). The systematic search for clinical trials was performed in the databases PubMed, CINAHL, Cochrane Central Register of Controlled Trials, PEDro, Scopus, SciELO and Dialnet. Articles were selected according to the inclusion and exclusion criteria, regarding the effectiveness of physical therapy interventions on adult patients with TTH published in the last 11 years with a score ≥ 6 in the PEDro Scale (Physiotherapy Evidence Database). (4) Results: In total, 120 articles were identified, of which 15 randomized controlled trials were finally included in order to determine the inclusion criteria. Changes in pain intensity, headache frequency or headache duration of individual studies were described (5) Conclusions: This systematic review shows that there is no standardized physical therapy protocol for the approach to tension headache, although all the techniques studied to date address in one way or another the cranio-cervical-mandibular region. The approach to the cranio-cervical-mandibular region reports significant effects in terms of decreasing the intensity of pain and frequency of headache episodes in the short and medium term. More long-term longitudinal studies are needed.

Large cell neuroendocrine carcinoma at the esophagogastric junction. An extremely rare entity.

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.

Recurrence of gastric schwannoma.

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.

Intra-abdominal abscess caused by Streptococcus constellatus in an immunocompetent patient.

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.

Importance of immunohistochemistry in the differential diagnosis of gastric mesenchymal tumors.

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.

Dual esophageal compression secondary to two vascular abnormalities.

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.

Intracorporeal Versus Extracorporeal Anastomosis in Patients Undergoing Laparoscopic Right Hemicolectomy: A Multicenter Randomized Clinical Trial (The IVEA-study).

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.

Use of barbed suture for the closure of enterocolotomy after laparoscopic right hemicolectomy with intracorporeal anastomosis. A prospective descriptive study. / Uso de la sutura barbada para el cierre de la enterocolotomía tras hemicolectomía derecha con anastomosis intracorpórea. Estudio prospectivo descriptivo.

INTRODUCTION: Performing intracorporeal anastomoses and sutures is possibly the technique that requires the greatest skill in laparoscopic surgery. The appearance of the new barbed sutures in recent years has seemed to facilitate this surgical step. The aim of our study is to evaluate short-term results in patients with neoplasms of the right colon, after laparoscopic right hemicolectomy with intracorporeal anastomosis using barbed suture at the closure of the enterocolotomy. METHODS: This is a multicenter, prospective, descriptive study that includes patients who underwent laparoscopic right hemicolectomy for neoplastic colonic pathologies between June 2015 and December 2018. In all patients, the intracorporeal anastomosis was performed using the endocutter, and closure of the enterocolotomy was done with a double layer of barbed suture. RESULTS: A total of 80 patients were treated (47.5% women), with an average age of 70.6±9 (49-92) years. The average operative time was 99.5±38minutes Anastomotic dehiscence was observed in 2.5% of the sample, and 5 patients required re-operation (6.2%) as a result of 2leaks, 2obstructive symptoms and one peritoneal bleeding. Mean hospital stay was 7 (3-173) days. CONCLUSIONS: The use of barbed suture in laparoscopic right hemicolectomy with intracorporeal anastomosis seems to present a morbidity similar to series described in literature. Prospective, controlled and randomized studies with a larger number of patients would be necessary to confirm these findings.

Efecto de la densidad de siembra en el desarrollo vegetativo del aguaje (Mauritia flexuosa L.f.) en plantaciones forestales / Effect of sowing density on the vegetative development of aguaje (Mauritia flexuosa L.f.) in forest plantations

En este trabajo es estudiado el efecto de dos densidades de siembra de la palmera aguaje (Mauritia flexuosa L.f.) sobre su crecimiento en altura; cuantificamos la proporción de plantas según sexo y determinamos los requerimientos ecológicos de iluminación y forma de copa del aguaje. El estudio se desarrolló en dos subparcelas con diferente densidad de siembra que fueron monitoreadas por 6 años después de 6 años de haber sido plantadas. Los resultados muestran que los individuos presentan mayor altura promedio y por lo tanto mayor crecimiento a mayor densidad de siembra. Es así que a los 12 años de establecidas las plantaciones, los individuos tuvieron en promedio 15.28 m y 13.1 m de altura a densidades de siembra mayores y menores, respectivamente. La proporción de palmeras fértiles se fue incrementando con el tiempo, siendo por lo general mayor a bajas densidades e incrementando en el tiempo la presencia de plantas femeninas. Existe una marcada competencia entre las copas de las palmeras por requerimientos de luz en las categorías buena y aceptable, por lo que se recomienda continuar con la evaluación y analizar el comportamiento futuro de las palmeras.

In this work, the effect of two planting distances of Mauritia flexuosa on its height is studied, quantified the sex ratio and ecological requirements needed by the species, e.g. light and crown shape. We conducted this study in two plots, each one with a different planting distance, which were monitored throughout 6 years starting after 6 years of the establishment of the plantations. Increased planting distance in between individuals gave increased average height and thus increased growth. Individuals planted with higher vs lower distances grew in average 15.28 m and 13.1 m in height respectively. The proportion of fertile palms increased throughout time and was lower in plantations with higher palm densities. The presence of female individuals increased also with time. There was a strong competition among palm crowns related to light requirements in good and acceptable categories. We recommended to continue with the evaluation and future analysis of this species' behavior.

Sexual satisfaction following bariatric surgery: A prospective exploratory study. / Satisfacción sexual tras cirugía bariátrica: estudio observacional prospectivo.

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.

Transanal endoscopic microsurgery for the treatment of uncommon rectal lesions. / Microcirugía endoscópica transanal en el tratamiento de lesiones rectales atípicas.

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.
