Massive Gastric Juvenile Polyposis Associated With Intermittent Gastric Outlet Obstruction: A Case Report.

Juvenile polyposis syndrome is a condition distinguished by numerous hyperproliferative polyps that can affect the entire gastrointestinal tract, though they are uncommon in the stomach. We report a rare case of a 70-year-old woman with a three-year history of epigastric pain and severe bloating who was referred to our department for gastric outlet obstruction due to massive gastric juvenile polyps also causing gastroparesis. The patient was successfully treated with a total gastrectomy.

Acute esophageal necrosis: A systematic review and pooled analysis.

BACKGROUND: Acute esophageal necrosis (AEN) is a rare entity with multifactorial etiology, usually presenting with signs of upper gastrointestinal bleeding. AIM: To systematically review all available data on demographics, clinical features, outcomes and management of this medical condition. METHODS: A systematic literature search was performed with respect to the PRISMA statement (end-of-search date: October 24, 2018). Data on the study design, interventions, participants and outcomes were extracted by two independent reviewers. RESULTS: Seventy-nine studies were included in this review. Overall, 114 patients with AEN were identified, of whom 83 were males and 31 females. Mean patient age was 62.1 ± 16.1. The most common presenting symptoms were melena, hematemesis or other manifestations of gastric bleeding (85%). The lower esophagus was most commonly involved (92.9%). The most widely implemented treatment modality was conservative treatment (75.4%), while surgical or endoscopic intervention was required in 24.6% of the cases. Mean overall follow-up was 66.2 ± 101.8 d. Overall 29.9% of patients died either during the initial hospital stay or during the follow-up period. Gastrointestinal symptoms on presentation [Odds ratio 3.50 (1.09-11.30), P = 0.03] and need for surgical or endoscopic treatment [surgical: Odds ratio 1.25 (1.03-1.51), P = 0.02; endoscopic: Odds ratio 1.4 (1.17-1.66), P < 0.01] were associated with increased odds of complications. A sub-analysis separating early versus late cases (after 2006) revealed a significantly increased frequency of surgical or endoscopic intervention (9.7 % vs 30.1% respectively, P = 0.04). CONCLUSION: AEN is a rare condition with controversial pathogenesis and unclear optimal management. Although the frequency of surgical and endoscopic intervention has increased in recent years, outcomes have remained the same. Therefore, further research work is needed to better understand how to best treat this potentially lethal disease.

Acid and nonacid gastroesophageal reflux after single anastomosis gastric bypass. An objective assessment using 24-hour multichannel intraluminal impedance-pH metry.

BACKGROUND: Single anastomosis gastric bypass (SaGB) was introduced in 2001 as an alternative to "loop" gastric bypass. It was considered as a procedure that would eliminate alkaline reflux and associated esophagitis. OBJECTIVES: Existing evidence about the postoperative incidence of gastroesophageal reflux (GERD) after SaGB is based on studies using symptom questionnaires. The aim of our study was to evaluate GERD 12 months after SaGB by using 24-hour multichannel intraluminal impedance pH metry (24-h MIIpH). SETTING: Surgical department of a university hospital METHODS: Morbidly obese candidates for SaGB underwent 24-hour MIIpH prior and 12 months after their bariatric procedure. RESULTS: There were 11 patients included in this prospective study. Results of 24-hour MIIpH revealed that DeMeester score (40.48 versus 24.16, P = .339) had an increasing trend 12 months after SaGB. Acid reflux episodes decreased, whereas nonacid reflux episodes increased postoperatively, both in proximal and distal esophagus. Total median bolus clearance time and acid clearance time increased. De novo GERD developed in 2 patients (28.6%) and worsening of already existing GERD developed in all patients with preoperative evidence of GERD. CONCLUSION: The use of symptom questionnaires to assess postoperative GERD after SaGB may not accurately depict the real image. Twenty-four-hour MIIpH in 12 months after SaGB revealed an increase of total number of nonacid reflux episodes and a decrease of total number of acid reflux episodes, with longer duration of each acid reflux episode. Close postoperative follow-up with reflux testing and possibly endoscopy could eliminate the risk of complicated GERD.

Esophageal remnant cancer 35 years after acidic caustic injury: A case report.

INTRODUCTION: Esophageal squamous cell carcinoma has been described as a long-term consequence following ingestion of corrosive substances. PRESENTATION OF CASE: We report a rare case of a 62-year-old female patient with a history of acidic caustic injury 35 years ago, for which she had undergone near total esophagogastrectomy with right colon interposition. Recently, she presented with worsening dysphagia, weight loss, neck swelling and chest pain. After the diagnostic workup, an invasive squamous cell carcinoma of the esophagus was confirmed. To our knowledge, this is the first such report in the literature. DISCUSSION: The risk for esophageal carcinoma increases substantially after ingestion of caustic substances. It is notable that distinct patterns of carcinogenesis between acids and alkalis may be postulated, since the corresponding pathophysiological impact of each one differ significantly. Although such esophageal cancers tend to have good prognosis due to early detection, both the diagnostic and therapeutic strategy may be challenging due to the limited available data in this field. Surgical treatment does not seem to eliminate the risk of cancer, as evident upon the present case report. CONCLUSION: Optimal management of esophageal corrosive injuries remains a debatable issue in terms of choosing between conservative therapy and surgical intervention. For this reason, the need for long-term follow up regardless the ingested substance and the preferred therapeutic approach is highlighted.

"Normal Values of 24H Multichannel Intraluminal Impedance pH-Metry in a Greek Obese Population Based on Montreal Definition of Gerd".

BACKGROUND: Although several studies reporting normal values of 24h multichannel intraluminal impedance pH (MIIpH) have been published, none of them has ever studied obese individuals. The purpose of this study is to determine overall frequency and duration of reflux episodes (acid and non-acid, supine-upright, post and preprandial) in obese asymptomatic volunteers. METHODS: Obese volunteers were enlisted during their preoperative evaluation for bariatric surgery. Volunteers had no gastroesophageal reflux disease (GERD) symptoms and no evidence of esophageal mucosal injury on endoscopy. Participants underwent a 24h MIIpH. RESULTS: In this prospective observational study, data of 22 obese individuals were analyzed. Mean age was 41.9 years and mean BMI was 47.1 kg/m(2). Mean total reflux episodes was 55.6 and 95th percentile was 99.7. Mean percentage of total time with pH <4 was 2.59 % and 95th percentile was 8.57 %. Mean percentage of bolus exposure was 1.84 % with 95th percentile being 4.47 %. Postprandial acid reflux episodes were statistical significant more frequent in comparison to preprandial acid reflux episodes (19.41 vs. 15, p = 0.008). Mean acid clearance duration was 3.6 times higher than median bolus clearance duration (56.05 and 15.55 s, respectively, p = 0.868). CONCLUSION: Our study is the first to provide normal values of 24h MIIpH of asymptomatic obese. Normal values of 24h MIIpH of obese asymptomatic individuals differ from the reported normal values of non-obese healthy individuals; having more reflux episodes and equal or slightly higher median bolus exposure and acid clearance. Our results imply that new cut-off values should be employed in order to define GERD in obese individuals.

Cutaneous metastases from esophageal adenocarcinoma.

The aim of this study is to present 2 rare cases of cutaneous metastases originated from adenocarcinoma of the gastro-esophageal junction, thus, underline the need for early diagnosis and possible treatment of suspicious skin lesions among patients with esophageal malignancy. Metastatic cancer to the skin originated from internal malignancies, mostly lung cancer, breast cancer, and colorectal cancer, constitute 0.5 to 9% of all metastatic cancers. (5, 8, 15) Skin metastases, mainly from squamous cell carcinomas of the esophagus, are rarely reported. Cutaneous metastasis is a finding indicating progressiveness of the disease. (17) More precisely, median survival is estimated approximately 4.7 months. (2, 14) This study is a retrospective review of 2 cases of patients with adenocarcinoma of the esophagus and a review of the literature. Two patients aged 60 and 32 years old, respectively, underwent esophagectomy. Both pathologic reports disclosed adenocarcinoma of the gastro-esophageal junction staged T3 N2 M0 (stage IIIB). During follow-up time, the 2 patients were diagnosed with cutaneous metastases originated from the primary esophageal tumor 11 and 4 months after surgery, respectively. The first patient is alive 37 months after diagnosis, while the second one died 16 months after surgery. Cutaneous metastasis caused by esophageal adenocarcinoma is possible. Therefore, follow-up of patients who were diagnosed with esophageal malignancy and underwent esophagectomy is mandatory in order to reveal early surgical stages.

GERD-Related Questionnaires and Obese Population: Can They Really Reflect the Severity of the Disease and the Impact of GERD on Quality of Patients' Life?

INTRODUCTION: There is a strong association between obesity and gastroesophageal reflux disease (GERD). GERD-related questionnaires have been developed in order to objectify symptoms. However, none of them has been tested in obese population. PURPOSE: The purpose of this study is to evaluate if GERD score and GERD-Health-Related Quality of Life (HRQL) can reflect severity of the disease and screen obese patients for GERD preoperatively. GERD's impact on the quality of life of obese patients is being assessed with the use of EORTC-QLQ C30. PATIENTS-METHODS: Obese patients during their preoperative evaluation were recruited regardless of the presence of GERD symptoms. A targeted GERD symptom history was obtained. Patients completed GERD score, GERD-HRQL, and EORTC-QLQ C30, and then, a 24-h multichannel intraluminal impedance pHmetry (MIIpH) was conducted. RESULTS: Forty-seven consecutive obese patients with mean age 39.91 years and mean BMI 46.94 kg/m(2) were included in the study. GERD score and GERD-HRQL have a positive linear correlation with DeMeester score (p = 0.001 and p < 0.001, respectively). EORTC QLQ-C30 does not correlate with DeMeester score. CONCLUSIONS: GERD-related questionnaires could be used in obese population as preoperative screening tool for GERD. However, our results indicate that the quality of life of obese patients is not affected by the existence of GERD.
