RESUMO
We present the first assessment of the diet of the blackchin guitarfish Glaucostegus cemiculus (Geoffroy Saint-Hilaire, 1817) for West Africa using DNA metabarcoding on stomach contents of individuals captured in the Bijagós Archipelago, Guinea-Bissau. The diet was dominated by crustaceans, particularly caramote prawn Penaeus kerathurus (frequency of occurrence [FO] = 74%, numerical frequency [NF] = 54%) and fiddler crab Afruca tangeri (FO = 74%, NF = 12%). Bony fishes were present in 30% of the stomachs. We highlight the importance of conservation action for intertidal habitats and their associated benthic invertebrates for the survival of the critically endangered blackchin guitarfish.

BACKGROUND : During endoscopic submucosal dissection (ESD), the normal mucosa is cut under constant optical control. We studied whether a positive horizontal resection margin after a complete en bloc ESD predicts local recurrence. METHODS: In this European multicenter cohort study, patients with a complete en bloc colorectal ESD were selected from prospective registries. Cases were defined by a horizontal resection margin that was positive or indeterminate for dysplasia (HM1), whereas controls had a free resection margin (HM0). Low risk lesions with submucosal invasion (T1) and margins free of carcinoma were analyzed separately. The main outcome was local recurrence. RESULTS: From 928 consecutive ESDs (2011-2020), 354 patients (40â% female; mean age 67 years, median follow-up 23.6 months), with 308 noninvasive lesions and 46 T1 lesions, were included. The recurrence rate for noninvasive lesions was 1/212 (0.5â%; 95â%CI 0.02â%-2.6â%) for HM0 vs. 2/96 (2.1â%; 95â%CI 0.57â%-7.3â%) for HM1.âThe recurrence rate for T1 lesions was 1/38 (2.6â%; 95â%CI 0.14â%-13.5â%) for HM0 vs. 2/8 (25â%; 95â%CI 7.2â%-59.1â%) for HM1. CONCLUSION: A positive horizontal resection margin after an en bloc ESD for noninvasive lesions is associated with a marginal nonsignificant increase in the local recurrence rate, equal to an ESD with clear horizontal margins. This could not be confirmed for T1 lesions.

A 17-year-old male with no previous medical history presented with a 1-year history of rectal bleeding, mucus discharge and occasional rectal prolapse. Colonoscopy revealed several polypoidal growth masses in the distal rectum, formed by multiple sessile polyps with a glistening mucus-covered surface and fleshy, friable appearance, that coalesced forming large conglomerates. Given their complexity and large size, piecemeal endoscopic mucosal resection of the rectal lesions was performed and histopathological examination revealed ulcerated polypoid mucosa with mixed inflammatory cell infiltrate in the lamina propria and dilated cystic mucus-filled glands. Remarkably, bony trabeculae surrounded by osteoblastic cells were also seen. These findings were consistent with juvenile polyps with foci of osseous metaplasia. Osseous metaplasia has been described in a wide variety of tissue types, such as prostate, uterus, breasts, lungs and urinary tract, with respect to both neoplastic and non-neoplastic conditions. However, it is exceedingly rare in colonic polyps and, to the best of our knowledge, only 9 cases have been described in juvenile polyps.

A 60-year-old female was diagnosed with acute myeloid leukemia. After initial remission with chemotherapy, she relapsed and underwent allogeneic hematopoietic stem cell transplantation (HSCT). Two months later, she presented to emergency department with watery diarrhea, abdominal pain and fever. She also tested positive for SARS-CoV2 on nasopharyngeal swab by polymerase chain reaction (PCR) and both cytomegalovirus (CMV) and Epstein-Barr virus (EBV) were detected in peripheral blood. Flexible sigmoidoscopy showed diffuse edema, erythema and loss of vascular pattern with interspersed segments of mucosal denudation and exudate and bBiopsies revealed epithelial cell apoptosis, diffuse crypt atrophy and dropout, with ulceration and both CMV and EBV were detected in colon mucosa, consistent with acute severe gastrointestinal graft-versus-host disease complicated by CMV and EBV superinfection. Despite starting therapy with methylprednisolone, ganciclovir and rituximab,she presented unfavorable evolution and died after 5 weeks.

An asymptomatic 38-year-old male with no significant previous medical history performed routine laboratory studies that revealed iron-deficiency anemia. Esophagogastroduodenoscopy and colonoscopy were unremarkable and he undergone videocapsule endoscopy that revealed multiple small polyps along jejunum and ileum. Double-balloon enteroscopy confirmed the presence of scattered small whitish nodules and small polyps carpeting segments of jejunal mucosal and sometimes forming conglomerates with a nodular appearance. Histopathological examination showed lamina propria expansion by neoplastic follicles, predominantly composed by small lymphoid cells that, by immunohistochemistry, showed expression of CD20, CD10 and bcl-2. Computed tomography scan of abdomen and pelvis did not reveal systemic involvement, consistent with primary small bowel follicular lymphoma. Chemotherapy was started and, at reevaluation enteroscopy, although nodular jejunal segments persisted, biopsies did not show involvement by lymphoproliferative disease, which was interpreted as complete remission. Periodic clinical and biochemical evaluation and annual enteroscopic surveillance was maintained and, after three years, local recurrence of low-grade follicular lymphoma was detected. As previously, there was no evidence of systemic involvement and the decision was to maintain close surveillance. After one year, the patient remains asymptomatic and without evidence of disease progression. This case illustrates the essential role of balloon-assisted enteroscopy for diagnosis and surveillance of primary small bowel follicular lymphoma.

A 51-year-old male with previous medical history of dyslipidemia performed screening colonoscopy, which revealed a sessile polypoid lesion with a diameter of approximately 8 mm located at the proximal transverse colon, which was resected en bloc with a cold snare. Remarkably, histopathological examination revealed a proliferation of spindle cells in the lamina propria entrapping colonic crypts without evidence of nuclear pleomorphism, mitotic figures or necrosis. On immunohistochemistry, spindle cells were diffusely positive for glucose transporter-1 and negative for S100, DOG1, CD34 and smooth muscle actin. These features were consistent with a diagnosis of colonic perineurioma.

A 40-year-old male with no previous medical history presented to emergency department with a 2-week history of progressive dyspnea. He also described night sweats and weight loss (15 kg) during the last 3 months. Thoraco-abdominal computed tomography showed multiple bilateral lung nodules associated with supra-clavicular, hilar and peri-esophageal lymphadenopathies and gastric parietal thickening. These imaging features were suggestive of primary gastric cancer with lung and lymph node metastases. Therefore, he undergone upper digestive endoscopy that showed a large ulcerated protruding lesion at the greater curvature of the body suggestive of malignancy. Gastric biopsies of the lesion confirmed a solid neoplasia constituted by solid nests and sheets of highly pleomorphic, bizarre cells with cytotrophoblastic and syncytiotrophoblastic differentiation that, on immunohistochemistry, stained positive for ß-HCG, SALL-4 and glypican-3. CT-guided biopsy of lung nodules revealed malignant cells with similar histopathological and immunohistochemical features. Elevated serum alpha-fetoprotein and ß-HCG were also detected. Clinical and ultrasound examination were negative for testicular masses. These findings were consistent with a primary gastric choriocarcinoma presenting with lung and lymph node metastases (stage IV). Although chemotherapy was started, the patient evolved unfavorably and died after 9 months. Primary gastric choriocarcinoma is a rare and aggressive gastrointestinal malignancy. This case demonstrates its rapid growth rate and high metastatic potential that may lead to symptoms from secondary involvement of distant organs.

BACKGROUND AND AIM: Amyloidosis is a systemic disease characterized by extracellular deposition of amyloid protein, most commonly in the heart and kidney. Hepatic amyloidosis is a rare form of presentation that ranges from mild hepatomegaly and altered liver biochemical tests to acute liver failure. The aims of this study were to evaluate the prevalence of amyloidosis in patients undergoing liver biopsy and describe its main clinical characteristics and prognostic impact. METHODS: A retrospective analysis of all patients with a histological diagnosis of hepatic amyloidosis between January 2010 and December 2019 was performed. MAJOR RESULTS: A total of 7 patients were identified from a total of 1773 liver biopsy procedures (0.4%), with a female predominance (6/7) and median age of diagnosis of 62 years. The most common clinical manifestations included hepatomegaly (4/7), jaundice (2/7) and peripheral edema (2/7), whereas 3/7 patients were asymptomatic. Every patient presented abnormalities in liver biochemical tests, more commonly cholestasis (6/7), but also cytolysis (4/7) or hyperbilirubinemia (2/7). Abnormal imaging findings included hepatomegaly, steatosis or parenchymal heterogeneity. In most patients (5/7), other organs were involved, most commonly with nephrotic syndrome (3/7) and infiltrative cardiomyopathy (3/7). The most common type was AA amyloidosis (3/7) followed by AL amyloidosis (2/7). The 1-year mortality rate was 43% and the median survival was 24 months. CONCLUSIONS: We report a low prevalence (0.4%) of amyloidosis among patients undergoing liver biopsy. Although rare, hepatic amyloidosis is associated with a dismal prognosis and a high index of suspicion is crucial to achieve an early diagnosis. .

A 54-year-old male with previous history of chronic hepatitis C complained of postprandial epigastric discomfort and weight loss. Esophagogastroduodenoscopy revealed a large gastric ulcer on the lesser antral curvature, with biopsies showing granulation tissue and inflammatory activity without other significant changes. Despite therapy with double-dose proton pump inhibitor, the ulcer had not healed or diminished in size at reevaluation endoscopy eight weeks later. Biopsies were repeated and again only revealed granulation tissue and inflammation. The patient undergone partial gastrectomy where fibrotic adhesions to liver and peritoneum were noted. Remarkably, macroscopical analysis of the surgical specimen revealed an hepatic fragment adherent to the ulcer and histopathological examination was consistent with liver penetration. Liver penetration is a rare but important complication that must be considered in the differential diagnosis of medically refractory gastric ulcers, even in the absence of hepatic tissue in endoscopic biopsies.

A 77-year-old female with previous medical history of non-cirrhotic chronic hepatitis B and hepatocellular carcinoma treated with sequential partial hepatectomy followed by transarterial chemoembolization complained of pruritus and jaundice. Magnetic resonance cholangiopancreatography revealed a peri-hilar ill-defined stenosing lesion suggestive of malignancy. Endoscopic retrograde cholangiopancreatography with cholangioscopy confirmed a circumferential peri-hilar stenosis with fragile mucosa and tortuous dilated vessels and biopsies of this area were consistent cholangiocarcinoma. After 3 months, she presented with new-onset dyspnea and bilioptysis and abdominal computed tomography revealed a bronchial-biliary fistula. ERCP was performed to place a self-expandable metal stent in the biliary tract, which resulted in rapid clinical improvement. The patient has been followed for 2 years and remains globally stable with two episodes of worsening of bilioptysis secondary to stent obstruction by lithiasis that were easily resolved with Fogarty balloon-assisted extraction, with rapid improvement. This case demonstrates the long-term efficacy of endoscopic biliary drainage with self-expandable metallic stent for bronchial-biliary fistula in the setting of cholangiocarcinoma. .

BACKGROUND AND AIM: gastric inflammatory fibroid polyps constitute only 0.1 % of all gastric polyps. They are usually amenable to resection by snare polypectomy. However, on rare occasions, these lesions may require resection by endoscopic submucosal dissection. This study aimed to evaluate the effectiveness and safety of endoscopic submucosal dissection in the management of gastric inflammatory fibroid polyps not amenable to resection with snare polypectomy. METHODS: a retrospective observational study of all consecutive patients who underwent endoscopic submucosal dissection for gastric inflammatory fibroid polyps between January 2011 and December 2020 was performed. RESULTS: there were nine cases of gastric inflammatory fibroid polyps resected by endoscopic submucosal dissection. Most patients were female (7/9) with a mean age of 62.2 years. All gastric inflammatory fibroid polyps were described as solitary antral subepithelial lesions with a mean diameter of 16.7 mm, which appeared well-circumscribed and homogeneous lesions located at muscularis mucosa and submucosa without deeper invasion on endoscopic ultrasound. All lesions were successfully resected by en bloc and complete resection with free margins obtained in 8/9 specimens. Adverse events were reported in 2/9 cases including one intra-procedural bleeding successfully controlled with hemostatic clips and one aspiration pneumonia that evolved favorably. Mean follow-up duration was 33.7 months and no delayed complications or cases of recurrence were reported. CONCLUSIONS: endoscopic submucosal dissection appears safe and effective for the resection of gastric inflammatory fibroid polyps that present as large subepithelial lesions, if performed by experienced endoscopists after adequate characterization by endoscopic ultrasound, with high rates of technical success and low recurrence rates.

Gastrointestinal involvement occurs in approximately 4% of cases of systemic amyloidosis. The most common site of amyloid deposition is small bowel, followed by stomach, colorectum and esophagus. Although rare, gastrointestinal amyloidosis may be associated with severe complications including gastrointestinal bleeding or perforation and may be mistaken for malignancy.

Background: The role of preoperative upper digestive endoscopy has been discussed with controversy in bariatric surgery. This study aims to evaluate the prevalence of endoscopic findings in obese patients undergoing bariatric surgery and their clinical impact. Methods: A retrospective observational study of all patients who performed upper endoscopy before bariatric surgery between January 2019 and December 2021 was performed. A total of 612 patients were identified, mostly females (79.2%), with a mean age of 43.9 years. Abnormal endoscopic findings were identified in 474 (77.5%) patients, including erythematous gastropathy (59.2%), reflux esophagitis (13.6%), erosive gastritis (10.6%), and hiatal hernia (8.0%). Importantly, Barrettâ??s esophagus was also identified in four patients and gastric adenocarcinoma in one. All performed gastric biopsies that revealed H. pylori gastritis in 368 (60.1%). Taken together, abnormal endoscopic and histological findings influenced perioperative management of 403 (65.8%) patients, including preoperative medical therapy in 378 (61.8%), endoscopic treatment of mucosal lesions in 47 (7.7%), direct influence in surgical strategy in 27 (7.8%) and contraindication to bariatric surgery in 1 (0.2%). Conclusion: Preoperative upper endoscopy identifies a wide range of abnormal findings in obese patients, which often influence peri-operative management. Therefore, it must be considered in all patients prior to bariatric surgery.

Background: Colonoscopy is currently the gold-standard for the detection of colorectal lesions, but its accuracy in tumor localization is limited. This study aims to determine the accuracy of colonoscopy in localization of colorectal malignancy, identify possible influencing factors and evaluate the surgical consequences of an incorrect preoperative localization. Methods: A retrospective cross-sectional study of all patients with colorectal malignant lesions diagnosed by colonoscopy who underwent subsequent resection surgery between January 2019 and December 2020 was performed. Colonoscopy accuracy was evaluated in terms of correspondence between endoscopic and intra-operative tumor localization. Results: A total of 115 patients were included, mostly males (63.5%), with mean age of 68.7 years. There was concordance between endoscopic and intra-operative localization in 76 cases, which corresponds to an accuracy of 66.1%. Colonoscopy completeness (p=0.008) and adequate bowel preparation (p=0.023) were significantly associated with greater concordance between endoscopic and intra-operative tumor location. Of the 39 incorrectly localized lesions, 19 (48.7%) required changes in surgical management. Conclusion: Colonoscopy is often inaccurate for localizing malignant colorectal lesions, which may frequently result in intra-operative changes in surgical strategy. Colonoscopy completeness and adequate bowel preparation were significant predictors for a correct endoscopic localization, underscoring the importance of colonoscopy quality for this particular indication.

INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) is a technically demanding procedure with a high risk for adverse events (AEs). AIM: evaluate patient- and procedure-related risk factors for ERCP-related AEs and develop an online app to estimate risk of AEs. METHODS: retrospective study of 1,491 consecutive patients who underwent 1,991 ERCPs between 2012 and 2017 was conducted. AEs definition and severity were classified according to most recent ESGE guidelines. Each variable was tested for association with occurrence of overall AEs, post-ERCP pancreatitis (PEP) and cholangitis. For each outcome, 2 regression models were built, from which an online Shiny-based app was created. RESULTS: Overall AE rate was 15.3%; in 19 procedures, >1 AE occurred. Main post-ERCP AE was PEP (7.5%), followed by cholangitis (4.9%), bleeding (1.3%), perforation (1%), cardiopulmonary events (0.9%), and cholecystitis (0.3%). Seventy-eight percent of AEs were mild/moderate; of severe (n = 55) and fatal (n = 20) AEs, more than half were related to infection, cardiac/pulmonary AEs, and perforation. AE-related mortality rate was 1%. When testing precannulation, procedural covariates, and ERCP findings, AE occurrence was associated with age (odds ratio [OR] 0.991), previous PEP (OR 2.198), ERCP complexity grade III/IV (OR 1.924), standard bile duct cannulation (OR 0.501), sphincterotomy (OR 1.441), metal biliary stent placement (OR 2.014), periprocedural bleeding (OR 3.024), and biliary duct lithiasis (OR 0.673). CONCLUSION: Our app may allow an optimization of the patients' care, by helping in the process of decision-making, not only regarding patient or endoscopist's selection but also definition of an adequate and tailored surveillance plan after the procedure.

A 50-year-old female with ulcerative colitis (UC) (pancolitis) for 13 years was referred for a screening colonoscopy. At onset, she presented with severely active disease and required intravenous corticosteroids to induce remission. Since then, the disease has been in remission with oral mesalamine and azathioprine and she remains steroid-free, without new episodes of hospitalization. She was asymptomatic and had no other relevant medical history.

We report a unique case of acute esophageal necrosis in association with perforated acute cholecystitis and secondary Klebsiella pneumoniae bacteremia. An 83-year-old male with history of diabetes mellitus, dyslipidemia, ischemic cardiomyopathy and recent right hemicolectomy for colon adenocarcinoma presented to emergency department with acute epigastric pain and hematemesis. The patient appeared cachectic and dehydrated. He was afebrile and hemodynamically stable. Laboratory studies revealed anemia, leukocytosis, hyponatremia and hyperlactatemia. Esophagogastroduodenoscopy displayed characteristic features of acute esophageal necrosis. Abdominal computerized tomography revealed acute cholecystitis with perforation contained by the liver. Percutaneous cholecystostomy was performed. Fluid therapy, intravenous pantoprazole and bowel rest were started. Klebsiella pneumoniae was cultured in blood and bile and broad-spectrum antibiotic therapy was administered. The patient improved clinically and, three weeks later, esophagogastroduodenoscopy demonstrated nearly complete healing of esophageal mucosa. To our knowledge, this is the first case of acute esophageal necrosis in association with acute cholecystitis.
