Validation and adaptation to Spanish of the quality-of-life questionnaire in patients with hemorrhoidal disease and anal fissure (HEMO-FISS-CdV).

Haemorrhoidal disease and anal fissure are the two most frequent entities within benign anal pathology, both of which have a negative impact on patients' quality of life. To date, there is no specific questionnaire in Spanish to assess the impact on quality of life in patients suffering from these conditions. The aim of our study is to validate in Spanish a questionnaire for this purpose, adapting it to our daily clinical practice. The HEMO-FISS-CdV is the Spanish version of the original HEMO-FISS-QoL by Abramowitz. The questionnaire consists of 23 items organised in 4 dimensions (physical, psychological, defecation and sexuality). The reliability of the new tool was assessed by determining internal consistency using Cronbach's alpha and Guttman's coefficient. It was also correlated with the quality of life questionnaire SF12 version 2. The Cronbach's alpha obtained for our questionnaire (HEMO-FISS-CdV) was 0.951 (ICC 95% +-0.016), with a range between 0.935 and 0.967. The Guttman two-half coefficient had a value of 0.910. Patients with internal haemorrhoids, anal fissure or both had higher values on the HEMO-FISS-CdV questionnaire than patients without internal haemorrhoids and these differences were significant (p<0.05). Both diseases have a negative impact on patients' quality of life. The HEMO-FISS-CdV questionnaire provides a tool in Spanish that easily and specifically assesses the impact of haemorrhoidal disease and anal fissure on quality of life.

Submucosal infiltrate of anisakis larvae. Rare cause of intestinal obstruction.

Patient aged 71 with a history of type 2 diabetes mellitus. He came to the emergency department for abdominal pain and vomiting. Laboratory tests showed an increase in acute phase reactants. Abdominal CT scan showed dilated jejunal loops, compatible with intestinal occlusion. Urgent intervention was performed, resecting the affected segment. The pathology report showed a prominent transmural inflammatory infiltrate and interstitial oedema, with moderate villous atrophy, identifying parasitic structures compatible with anisakis larvae (family Anisakidae). Given the mechanism of tissue invasion, the larvae are surrounded by a predominantly eosinophilic inflammatory infiltrate, organised as granulomas or abscesses.

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.

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.

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.

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.

Management of a hydatid cyst in a center with high prevalence. Descriptive series.

Hydatidosis is a zoonosis caused by the larval stage of the genus Echinococcus. Humans are an accidental intermediate host. The main organ affected is the liver (70%). The incidence increases in endemic regions such as North Africa, Eastern Europe and South America. We present a descriptive series of cases treated in our hospital in the last 5 years. Demographic variables, cyst characteristics, as well as preoperative and postoperative variables are collected.

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.

Results of the national registry of patients diagnosed with inflammatory bowel disease candidates for bariatric surgery (ReNacEIBar).

BACKGROUND: Our aim is to carry out a national registry of patients with inflammatory bowel disease (IBD) who underwent bariatric surgery, as well as evaluate the results and management of this type of patients in the usual clinical practice. METHODS: National multicentric observational retrospective study, including patients, previously diagnosed with IBD who underwent bariatric surgery from January 2000 to December 2022. RESULTS: Forty-one patients have been included: 43,9% previously diagnosed with ulcerative colitis, 57,3% Crohn's disease, and an indeterminate colitis (2,4%). The preoperative BMI was 45.8 ± 6,1 kg/m2. Among the bariatric surgeries, 31 (75,6%) sleeve gastrectomy, 1 (2,4%) gastric bypass and 9 (22%) one anastomosis gastric have been carried out. During the postoperative period, 9.8% complications have been recorded. BMI was 29,5 ± 4,7 kg/m2 and percent total weight lost was 33,9 ± 9,1% at 12 months. CONCLUSIONS: Bariatric surgery in patients with inflammatory bowel disease can be considered safe and effective.

Revisional One-Anastomosis Gastric Bypass (OAGB) After Intrathoracic Migration of Nissen Fundoplication.

According to the latest IFSO recommendations, bariatric and metabolic surgery is the recommended treatment for patients with a BMI above 35 kg/m2 (with or without associated pathology), achieving good results in terms of weight loss in the medium to long term, as well as improving a significant percentage of comorbidities in this type of patient (diabetes mellitus, arterial hypertension, dyslipidaemia, gastro-esophageal reflux disease (GERD)...). The incidence of GERD is higher in patients with obesity, with more severe symptoms. Over the years, Nissen fundoplication has been the gold standard treatment for patients with GERD who do not respond to medical treatment. However, in patients with obesity, gastric bypass is a valid option to consider. We present the case of a patient who had previously undergone anti-reflux surgery (laparoscopic Nissen) for GERD, with favorable evolution, who presented intrathoracic migration of the same after 8 years, with new onset of symptoms, and who was offered revision bariatric surgery. The video presents on the performance of OAGB in a patient who had previously undergone antireflux surgery, with intrathoracic Nissen. Performing this technique after a previous Nissen fundoplication (as well as migration of the Nissen) is a somewhat more complex procedure than primary surgery but can be performed safely with careful technique (there are often previous adhesions that hinder mobility and separation of the fundoplication) and provides good symptom control.

Bile reflux and marginal ulcers after one-anastomosis gastric bypass (OAGB). A narrative review.

One-anastomosis gastric bypass has now become the third most commonly performed bariatric technique worldwide. However, as a consequence of the configuration of this surgery, it can present some chronic complications (anastomotic mouth ulcers and biliary reflux) that physicians must come to better understand and assess. In this narrative review, we aimed to update our knowledge of both the diagnosis and treatment of these two complications in the context of bariatric surgeries. We concluded that a series of pre-, intra-, and postoperative preventive strategies should be considered by surgeons to help reduce the appearance of these complications.
