RESUMO

The small bowel is an uncommon site for cancer metastasis. Despite this, cases have reported the duodenum as a metastatic site from local organs. However, duodenal involvement from more distant organs, such as the ovaries, has rarely been reported. Herein, we present a case of a 68-year-old female who developed duodenal metastatic disease from a primary ovarian serous adenocarcinoma. The goal of this report is to encourage clinicians to keep a broad differential in patients complaining of abdominal pain, especially in those with a history of primary ovarian malignancy.

RESUMO

With current life expectancies exceeding 78 years on average, to be confronted with the discovery of a rare cancer often found in advanced stages is a startling devastation. Angiosarcoma of the intestine is a rare and aggressive tumor that is not often considered in the differential diagnosis of intestinal obstruction. Once found and accurately diagnosed, it is a bewildering race against time as its median survival time is 150 days from diagnosis. This case report details a rare small intestinal angiosarcoma with its host surpassing current epidemiological standards of survival time despite only being eligible for chemotherapy.

RESUMO

Cytomegalovirus (CMV) is an aggressive virus responsible for a considerable amount of case fatalities. In the overwhelming majority of cases, this affects only the immunocompromised. Herein, we present a 76-year-old immunocompetent female who presented with gastrointestinal bleeding found to have rectal ulceration secondary to CMV infection. This manuscript aims to raise awareness of a rare cause of rectal bleeding. Hopefully, as such, our case will also prevent long-standing inflammation from persisting in patients with CMV and prevent it from contributing to cardiovascular pathology as seen in our patient.

RESUMO

A colonic perineurioma is often considered a benign cousin to a colonic polyp. However, in the submucosal type of perineurioma, it is important to rule out the malignant gastrointestinal stromal tumor (GIST). Alternatively, in the BRAF-positive serrated types of perineuriomas, surveillance is equivalent to intervals designated to serrated polyps due to a similar malignant potential. These versions serve as reminders that colonic perineuriomas are not to be disregarded.

RESUMO

Xanthomas within the gastrointestinal tract occur secondary to a mucosal insult. When enough cells accumulate, their appearance can range from small nodules studding the intestinal mucosa to bandlike infiltrations to pseudotumor-like masses within the intestine with fibrosis and inflammation resembling malignancy. When large enough, they can produce symptoms of obstruction such as vomiting, abdominal pain, distention, and dysmotility. This case demonstrates the epidemiology, clinical presentation, diagnosis, and treatment of duodenal xanthomas.

RESUMO

Background and study aims The use of lumen apposing metal stents (LAMS) during EUS-guided transmural drainage (EUS-TD) of pancreatic walled-off necrosis (WON) has gained popularity. Data supporting their use in WON over plastic stents (PS), however, remain scarce. The aim of this study was to compare the clinical efficacy of LAMS (Axios, Boston Scientific) with PS in WON. Patients and methods This was a multicenter, retrospective study involving 14 centers. Consecutive patients who underwent EUS-TD of WON (2012 - 2016) were included. The primary end point was clinical success defined as WON size ≤ 3 cm within a 6-month period without need for percutaneous drainage (PCD) or surgery. Results A total of 189 patients (mean age 55.2 ±â€Š15.6 years, 34.9 % female) were included (102 LAMS and 87 PS). Technical success rates were similar: 100 % in LAMS and 98.9 % in PS ( P  = 0.28). Clinical success was attained in 80.4 % of LAMS and 57.5 % of PS ( P  = 0.001). Rate of PCD was similar (13.7 % LAMS vs. 16.3 % PS, P  = 0.62), while PS was associated with a greater need for surgery (16.1 % PS vs. 5.6 % LAMS, P  = 0.02). Adverse events (AEs) were observed in 9.8 % of LAMS and 10.3 % of PS ( P  = 0.90) and were rated as severe in 2.0 % and 6.9 %, respectively ( P  = 0.93). After excluding patients with < 6 months follow-up, the rate of WON recurrence following initial clinical success was greater with PS (22.9 % PS vs. 5.6 % LAMS, P  = 0.04). Conclusions When compared to PS, LAMS in WON is associated with higher clinical success, shorter procedure time, lower need for surgery, and lower rate of recurrence.

RESUMO

Background and study aims Accurate diagnosis and classification of pancreatic cysts (PCs) remains a challenge. The aims of this study were to: (1) evaluate the safety and technical success of a novel microforceps for EUS-guided through-the-needle biopsy (TTNB) of PCs; and (2) assess its diagnostic yield for mucinous PCs when compared to FNA cyst fluid analysis and cytology. Patients and methods This was a multicenter retrospective analysis of 47 patients who underwent EUS-FNA and TTNB for PCs between January 2014 and June 2017. Technical success was defined as acquisition of a specimen adequate for cytologic or histological evaluation. Cyst fluid carcinoembryonic antigen (CEA) was used to initially categorize cysts as non-mucinous (CEA < 192 ng/mL) or mucinous (CEA ≥ 192 ng/mL). Final diagnosis was based on identifiable mucinous pancreatic cystic epithelium on cytology, microforceps histology and/or surgical histology when available. Results Forty-seven patients with PCs (mean size 30.7 mm) were included. TTNB was successfully performed in 46 of 47 (97.9 %). Technical success was significantly lower with FNA (48.9 %) compared to TTNB (85.1 %) ( P  < .001). For cysts with insufficient amount of fluid for CEA (n = 19) or CEA < 192 ng/mL, the cumulative incremental diagnostic yield of a mucinous PC was significantly higher with TTNB vs. FNA (52.6 % vs 18.4 %; P  = .004). TTNB alone (34.4 %) diagnosed more mucinous PCs than either CEA ≥ 192 ng/mL alone (6.3 %) or when combined with FNA cytology (9.4 %). One episode of self-limited bleeding (2.1 %) and one of pancreatitis (2.1 %) occurred. Conclusions EUS-TTNB is safe and effective for evaluating PCs. TTNB may help increase the diagnostic yield of mucinous PCs.

RESUMO

Henoch-Schonlein purpura (HSP) is an immune-mediated vasculitis. HSP presents with purple spots on the skin (purpura), arthralgia, digestive problems, and kidney injury. HSP is most commonly seen in children, and rarely presents in adults. The pathogenesis involves the deposition of immune complexes in small to medium size blood vessels which leads to necrosis and inflammation. Most patients recover after symptomatic treatment, while more severe cases are treated with steroids. We report a 28-year-old female patient who presented with two episodes of hematemesis, worsening abdominal pain, and bloody diarrhea. Physical examination showed erythematous, palpable, purpuric rashes on her thighs and lower legs. Contrast-enhanced computed tomography (CT) scan showed thickening of the duodenal wall, and upper endoscopy revealed mild gastric erythema and diffuse erythematous, hemorrhagic, friable mucosa with superficial, thick, adherent white exudate seen in the second portion of the duodenum, consistent with the diagnosis of HSP. We report on the clinical presentation of our patient, and review adult-onset HSP.

RESUMO

BACKGROUND AND STUDY AIMS: Laparoscopic sleeve gastrectomy (LSG) is gaining popularity in treating morbid obesity. Prior studies showed a 3.5% risk of gastric sleeve stenosis (GSS). There is no consensus on how to treat these patients, and the role of endoscopic therapy has been addressed in only a few studies. We aim to assess the efficacy and safety of endoscopic stenting in the management of GSS following LSG. PATIENTS AND METHODS: Retrospective data were reviewed from July 2009 to November 2013. Patients were referred for endoscopic therapy for symptoms or imaging findings suggestive of gastric leak or narrowing following LSG. Endoscopic therapy included the use of fully covered self-expanding esophageal metal stents (FCSEMS) in addition to over-the-scope clip system (OTSC) when necessary. RESULTS: All 27 patients were females with mean age of 40 years; six patients were excluded from the study. Major symptom was nausea and vomiting in 57% of the patients. Five of 21 patients had concomitant leaks. All 21 patients underwent FCSEMS placement, and four out of five patients (80%) with concomitant leak had OTSC. The success rate in both groups for resolution of stricture and leak was 100%, and no surgical intervention was required. There were no immediate or delayed complications of endoscopic therapy. Median follow-up of 6 months was available for 20/21 patients. Among patients with gastric leak, 80% had resolution of their symptoms compared with 93% of patients with GSS. CONCLUSIONS: Endoscopic therapy for LSG-related GSS or leaks with FCSEMS is highly effective and safe.

RESUMO

Oesophageal ulcers are a rare cause of upper Gastrointestinal Bleeding (GIB). In patients with Acquired Immune Deficiency Syndrome (AIDS), oesophageal diseases including oesophageal ulcers are very common. Idiopathic Oesophageal Ulcers (IOU) comprises a subgroup of oesophageal ulcers with no identifiable cause. IOU mainly present as odynophagia, retrosternal chest pain, decreased oral intake, and weight loss. Upper GIB is a rare presentation. In the era of Highly Active Anti Retroviral Therapy (HAART), with improvement in CD4 count, this entity is almost forgotten.

RESUMO

Gastric volvulus has been reported in all age groups; however, it is typically diagnosed in the elderly. Organo-axial volvulus is the most common type, followed by the mesentero-axial and the combined types. Depending on the etiology, gastric volvulus can also be classified as primary (idiopathic) or secondary. Treatment of acute gastric volvulus involves laparoscopic or endoscopic procedures/maneuvers, depending on the severity of symptoms and surgical eligibility of the patient. Chronic gastric volvulus is typically managed conservatively, although laparoscopic or endoscopic interventions can also be employed depending on the severity of presentation.

RESUMO

Liver injury in the setting of human immunodeficiency virus (HIV) infection is more commonly attributed to viral hepatitis or highly active antiretroviral treatment (HAART) toxicity. The severity of liver injury is an important cause of morbidity and mortality. The emergence of autoimmune diseases, particularly autoimmune hepatitis (AIH) in the setting of HIV infection, is rare. Previous reports indicate that elevated liver enzymes are a common denominator amongst these patients. We present two patients with HIV infection, on HAART, with virological suppression. Both patients presented with elevated liver enzymes, and following liver biopsies, were diagnosed with AIH. The clinical course of these patients underscore the therapeutic value of corticosteroids, and in some cases, addition of immunosuppression for AIH treatment.

RESUMO

The use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) appears to be a safe and feasible means of confirming or excluding malignancy in the adrenal glands. EUS-FNA with biopsy of suspicious masses in either adrenal gland allows for assessment of these lesions while keeping complications relatively rare. The main advantages of EUS-FNA are that it can be done as an outpatient procedure, with good results, minimal morbidity, and a short hospital stay. Nevertheless, EUS-FNA of adrenal masses should be indicated only in selected cases, in which there is potential to either decrease unnecessary treatment or guide therapy in cancer patients by aiding in either staging of malignancy or treatment of recurrence.v.

RESUMO

BACKGROUND: Due to the large number of Roux-en-Y gastric bypass surgeries performed over the last decade, reversal of the bypass to normal anatomy has been increasingly reported. SETTING: University affiliated Teaching Hospital, United States. OBJECTIVES: The aim of this systematic review was to summarize the literature data regarding the indications, technical considerations, and outcomes of gastric bypass reversal. METHODS: PubMed/MEDLINE search was conducted for articles reporting reversal of gastric bypass to normal anatomy. Patients' demographic characteristics, primary reason for reversal, reversal technique, and postreversal events were retrieved and categorized from each eligible paper. RESULTS: Thirty-five articles encompassing a total of 100 patients were eligible. Malnutrition was the most common indication for reversal (12.3%), followed by severe dumping syndrome (9.4%), postprandial hypoglycemia (8.5%), and excessive weight loss (8.5%). Techniques for gastrogastrostomy were available in 42 patients, with the hand-sewn technique as the most common (67.4%) followed by the linear stapler (23.2%) and the end-to-end anastomosis stapler used in 3 patients (6.9%). The reversal technique was performed endoscopically and described in 3 studies (3 patients). Techniques for handling the Roux limb were described in 56 patients (56%); the limb was reconnected in 32 patients (57.2%) and resected in 24 patients (42.8%). Weight regain was the most prevalent postreversal event (28.8%), followed by severe gastroesophageal reflux diseases (10.2%) and persistent abdominal pain (6.8%). There was no reported mortality. CONCLUSION: Gastric bypass reversal is indicated for excessive weight loss, dumping syndrome, and postprandial hypoglycemia. The procedure is well tolerated and feasible when performed laparoscopically and has no reported mortality.
