RESUMEN

Functional dyspepsia (FD) is a prevalent chronic digestive disorder that significantly impacts patients' quality of life. Sleep disturbance (SD) is common among FD patients, yet the relationship between SD and FD remains poorly characterized. This systematic review explores the bidirectional relationship between FD and SD, investigating underlying mechanisms and implications for management. A rigorous and comprehensive systematic search was conducted across PubMed, PubMed Central (PMC), Google Scholar, Cochrane Library, and ScienceDirect using select keywords related to SD and FD. Only studies published in English from the past 10 years that met inclusion and exclusion criteria were included. Quality assessment tools specific to study types were employed to minimize bias. After applying inclusion and exclusion criteria and quality assessments, the review encompassed 30 studies. The key findings reveal that FD is frequently associated with SD, with a significant proportion of FD patients reporting poor sleep quality. The mechanisms linking SD and FD are complex, involving the circadian rhythm, visceral hypersensitivity, immune responses, and psychological factors. Nonpharmacological treatments like cognitive behavioral therapy (CBT), acupuncture, and pharmacological neuromodulators have shown promise in managing FD and SD, offering hope for improved patient outcomes. SD and FD share a significant bidirectional relationship, influenced by a complex interplay of physiological, psychological, and lifestyle factors. Addressing SD in FD patients may improve overall symptom management. Further research is crucial, as it should focus on isolating specific SD causes and their direct impacts on FD and other functional gastrointestinal disorders (FGIDs), opening up new avenues for understanding and treatment.

RESUMEN

Intraperitoneal focal fat infarction (IFFI) is a rare condition characterized by infarction of fatty tissue within the abdominal cavity. Lesser omental infarction, a relatively rare type of IFFI, occurs when there is an infarction of fat within the lesser omentum. Patients typically present with acute abdominal pain that can mimic more serious conditions. This case report highlights the clinical presentation, diagnostic challenges, and management strategies for patients presenting to the emergency department with lesser omental infarction. A 63-year-old female presented to the emergency department with a chief complaint of epigastric abdominal pain that had been persisting for approximately a week and a half. The pain, which initially seemed like a sore muscle, became increasingly sharp and intermittent, with tenderness upon palpation of the epigastric area. Computed tomography (CT) imaging revealed an omental infarct in the lesser sac with focal inflammation in the fat of the lesser omentum. Through conservative management with analgesics and anti-inflammatory medication, the patient experienced resolution of her symptoms within a few days and had a follow-up with the gastrointestinal team several weeks later. Lesser omental infarction typically results from compromised blood flow due to torsion or thrombosis, leading to ischemia and necrosis of the fatty tissue. CT imaging is crucial for its diagnosis and reveals fat-density lesions with surrounding inflammatory changes. Conservative management is typically effective, though in rare cases, surgical intervention may be necessary when significant vital signs and electrolyte derangements occur.

RESUMEN

A hiatal hernia occurs when the contents of the abdominal cavity, most often the stomach, protrude into the chest cavity through the esophageal hiatus. The hiatus is an elliptical-shaped outlet, typically formed by parts of the right diaphragmatic crus surrounding the distal esophagus. This ailment can transpire due to either the broadening of the specific diaphragmatic opening or a shortening in the overall length of the esophagus, leading to herniation of the stomach into the thoracic region. Raised pressure in the abdominal region may also be one of the culprits. Patients with a hiatal hernia usually remain asymptomatic, but patients might have difficulty swallowing both liquids and solids in the advanced stages of the disease. The disease is rarely accompanied by reflux of gastric acid into the esophagus due to decreased activity of the lower esophageal sphincter, leading to increased complaints of epigastric pain and ulceration near the gastroesophageal junction. Long-standing cases can increase the risk of developing Barrett's esophagus with dysplasia, which may advance to esophageal carcinoma in later stages. Advanced age and obesity are significant risk factors for hiatal hernia. Obese individuals, in particular, experience higher intra-abdominal pressure, which significantly raises the likelihood of developing a hiatal hernia. The hernia may be diagnosed through an upper gastrointestinal endoscopy or radiologically through a chest X-ray in the posterior-anterior view, defining the border of the esophagus. Hence, this facilitates a more seamless and precise diagnosis. Surgical fundoplication treatment improves the patient's condition better than solitary medical management. Overall, addressing the condition surgically often yields more favorable outcomes and enhances the patient's quality of life. Hiatal hernia usually presents with no or minimal clinical manifestations. Thus, this case report highlights the importance of comprehensive clinical management of such cases.

RESUMEN

Endoscopic biliary stenting is a well-established intervention for the treatment of biliary, hepatic, and pancreatic disorders. The common indications include strictures, neoplasms, stones, infections, and bile leaks. Stents can be occluded, predisposing patients to ascending cholangitis and biliary sepsis. Distal stent migration is another known complication of endoscopic stenting and is usually spontaneous. Bowel perforation, abscesses, bleeding, and pancreatitis are rare complications of distal stent migration and are usually limited to the duodenum. Herein, we describe an extremely rare case of bilio-cecal stent migration presenting as rectal bleeding.

RESUMEN

OBJECTIVE: The objective of this study is to compare the psychosocial characteristics of functional dyspepsia (FD) with its subgroups, epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS), against a healthy control group, and to investigate the quality of life (QoL). METHODS: All of the subjects were 210 adults, 131 patients with FD were diagnosed by gastroenterologist and 79 adults with no observable symptoms of FD were selected as the normal control group. Demographic factors were investigated. The Korean-Beck Depression Inventory-II, Korean-Beck Anxiety Inventory, Korean-Childhood Trauma Questionnaire, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale, and WHO Quality of Life Assessment Instrument Brief Form were used to assess psychological factors. A one-way analysis of variance was used to compare differences among the groups. Further, a stepwise regression analysis was conducted to determine factors affecting the QoL of the FD group. RESULTS: Between-group differences in demographic characteristics were not significant. Depression (F=37.166, p<0.001), anxiety (F=30.261, p<0.001), and childhood trauma (F=6.591, p<0.01) were all significantly higher in FD group compared to the normal control. Among FD subgroups, EPS exhibited higher levels of both depression and anxiety than PDS. Social support (F=17.673, p<0.001) and resilience (F=8.425, p<0.001) were significantly lower in FD group than in other groups, and the values were higher in PDS than in EPS. Resilience (ß=0.328, p<0.001) was the most important explanatory variable. The explained variance was 46.6%. CONCLUSION: Significantly more symptoms of depression, anxiety, childhood trauma was observed for both FD sub-group. These groups also had less social support, resilience, and QoL than the control groups.

RESUMEN

Background: We describe a rare case of giant adrenal calcification as the main cause of sudden onset epigastric pain in a 57-year-old female patient. Case description: Computed tomography (CT) of the whole abdomen in this patient showed calcified foci measuring approximately 7.8 × 5.4 × 7.1 cm in the hepatorenal recess, and no enhancement effect was seen. Secondary causes of adrenal calcification in this patient were ruled out, and a rare diagnosis of a primary giant adrenal calcification was made. Subsequently, the right adrenal gland and calcified mass were completely resected. The calcification did not recur during 6 months of follow up. Conclusions: Although other cases of adrenal calcification of unknown origin have been reported, cases of giant idiopathic adrenal calcification are rare. In this case, huge calcification of the right adrenal gland caused abdominal pain, which disappeared after the mass was excised. The etiology, pathogenesis, clinical symptoms, and prognosis of idiopathic adrenal calcification are still unclear. Additional case reports are needed to gain a better understanding of the diagnosis and treatment of this condition.

RESUMEN

Pancreatitis can produce several complications such as pseudocyst, which can happen in acute and chronic pancreatitides. Pseudocysts are typically found in the abdomen but can rarely extend into the mediastinum. Atypical symptoms such as dyspnea, dysphagia, coughing, vomiting, abdominal or chest pain, and hemoptysis are usually the notable complaints. CT scan, MRI, and endoscopic ultrasound are valuable diagnostic modalities. Drainage and surgical removal of the pseudocyst are the treatment options. Herein, we outline the case of a young female with episodic chest and epigastric discomfort, dysphagia, and weight loss. Previously, she was incorrectly diagnosed with gastroesophageal reflux disease and peptic ulcer. A mediastinal pseudocyst secondary to chronic pancreatitis was found to be the cause. The patient underwent surgical removal of the pseudocyst and a pancreaticojejunostomy. Significant improvement was noticed at follow-up. This article highlights the possibility of such unusual conditions and the importance of a proper assessment while treating patients with epigastric pain.

RESUMEN

Gastrointestinal duplication is an infrequent congenital disorder characterized by the presence of a muscular layer covered by mucosa. Gastric duplication cysts account for approximately 2%-9% of all gastrointestinal duplication cysts. The typical clinical presentation often includes symptoms such as epigastric pain, vomiting, and the presence of a palpable abdominal mass. However, these symptoms can overlap with more common conditions. Diagnostic confirmation usually necessitates additional imaging studies, and surgical intervention is the recommended treatment approach. In this case report, we present the case of a 9-year-old girl who presented with chronic abdominal pain and vomiting. Following a comprehensive evaluation, including a CT scan and various diagnostic tests, a diagnosis of gastric duplication cyst was established. The patient subsequently underwent a laparotomy procedure, during which the cyst was completely excised. Follow-up visits indicated an uneventful recovery, with complete resolution of all symptoms. The aim of this work is to report on the clinico-radiological aspects of gastric duplication cysts and their surgical treatment.

RESUMEN

Testicular cancer is among the most common solid tumors in young men. Gastrointestinal tract (GIT) metastasis of testicular cancer has been rarely reported. In addition, metastasis occurs most commonly through retroperitoneal lymph nodes. Manifestations like abdominal pain and obstruction can be present if metastasis to GIT was considered. We report here a case of a 34-year-old male who was admitted to our GIT unit complaining of episodic epigastric pain. Computed Tomogram (CT) scan demonstrated a soft tissue like lesion involving the lumen of duodenum. Moreover, the patient had a right radical orchiectomy 18 months prior to the presentation due to a stage IA non-seminomatous germ cell tumor with no lymphovascular invasion and free surgical margins. Esophagogastroduodenoscopy (EGD) revealed a malignant appearing duodenal lesion and biopsy showed that it was compatible with germ cell tumor. Metastatic embryonal carcinoma to duodenum was diagnosed and confirmed by immunohistochemical stains. Then, the patient's situation was discussed and decided to be on a plan of four cycles of chemotherapy regimens. Testicular malignancy metastasis to GIT is uncommon, but it's important to know that there is a contact between GIT and testicular lymphatic drainage through para-aortic lymph nodes. So, even if it's rare to occur, it's still possible, and we should always be concerned about it. Mostly, diagnosis of testicular tumors begins with evaluating tumor markers such as alpha-fetoprotein (AFP), beta-subunit of human chorionic gonadotropin (B-hCG), and lactate dehydrogenase (LDH). But in contrast, all of these markers were within the normal range of their values in our case. Suspicion for metastasis and GIT involvement must be raised when dealing with a young male who had a history of testicular tumor such as embryonal carcinoma which was reported here in our case. That is very essential for avoiding potential complications and saving time in order to start management.

RESUMEN

Hypobicarbonatemia with an elevated anion gap on a metabolic panel is frequently the initial marker of a life-threatening condition such as diabetic ketoacidosis in a patient with epigastric pain. The two commonly used means of measuring bicarbonate levels are direct measurement from a metabolic panel and calculated measurement from arterial blood gas. In this case report, we would like to highlight a potentially serious deficiency in one of these two means and how it may lead to a dangerous misdiagnosis and subsequent mismanagement. We also shine a light on potential measures to counteract or prevent this undesirable outcome.

RESUMEN

Key Clinical Message: When seeing patients who present with atypical lymphocytes and abdominal pain without accompanying symptoms of pharyngitis or lymphadenopathy, acalculous cholecystitis caused by CMV infection should be considered as a differential diagnosis. Abstract: A teenage man presented with a fever and epigastric pain. The patient tested positive for cytomegalovirus IgG and IgM. Abdominal ultrasonography and contrast-enhanced CT revealed hepatosplenomegaly and gallbladder wall thickening. MRI did not identify gallstones or tumorous lesions. He was diagnosed with infectious mononucleosis and acalculous cholecystitis caused by cytomegalovirus.

RESUMEN

Gastrointestinal amyloidosis is a rare condition commonly found in the setting of systemic AL amyloidosis. Amyloid can deposit throughout the gastrointestinal tract and the resulting symptoms vary depending on the site of deposition. Gastrointestinal (GI) manifestations can range from weight loss or abdominal pain, to more serious complications like gastrointestinal bleeding, malabsorption, dysmotility, and obstruction. This case describes a patient with known history of IgG lambda AL amyloidosis, presenting with epigastric pain and unintentional weight loss found to have gastroduodenal amyloidosis. The definitive diagnosis of GI amyloidosis requires endoscopic biopsy with Congo red staining and visualization under polarized light microscopy. There are currently no specific guidelines for the management of GI amyloidosis. Generally, the goal is to treat the underlying cause of the amyloidosis along with symptom management. Our patient is being treated with cyclophosphamide, bortezomib, and dexamethasone (CyBorD) and started on hemodialysis due to progression of renal disease.

RESUMEN

BACKGROUND: Glutaric aciduria type II (GA II), also known as multiple acyl-CoA dehydrogenase deficiency (MADD), is a rare autosomal recessive metabolic disorder with varied manifestations and onset ages. CASE REPORT: This study presents a distinctive case of a 10-year-old girl who experienced episodic, intermittent vomiting and epigastric pain, particularly aggravated by high-fat and sweet foods. Despite inconclusive physical examinations and routine laboratory tests, and an initial suspicion of cyclic vomiting syndrome, the persistence of recurrent symptoms and metabolic abnormalities (metabolic acidosis and hypoglycemia) during her third hospital admission necessitated further investigation. Advanced diagnostic tests, including urinary organic acid analysis and genetic testing, identified heterozygous pathogenic variants in the ETFDH gene, confirming a diagnosis of GA IIc. The patient showed a positive response to a custom low-protein, low-fat diet supplemented with carnitine and riboflavin. SIGNIFICANCE: This case emphasizes the diagnostic challenges associated with recurrent, nonspecific gastrointestinal symptoms in pediatric patients, particularly in differentiating between common gastrointestinal disorders and rare metabolic disorders like GA II. It highlights the importance of considering a broad differential diagnosis to enhance understanding and guide future medical approaches in similar cases.

RESUMEN

Peripheral T cell lymphoma (PTCL) is a rare form of non-Hodgkin lymphoma characterized by the origin of mature T-cells. PTCL demonstrates atypical clinical features and involves both nodal and extra-nodal sites. The diagnosis and treatment of PTCL can prove to be challenging, as it is often detected at advanced stages and is resistant to conventional chemotherapy treatments. The present report describes a 55-year-old male patient who presented with acute pancreatitis, and imaging suggested a soft tissue mass in the pancreatic head indicating pancreatic adenocarcinoma. Further investigation through ultrasound-guided biopsy led to the diagnosis of pancreatic PTCL not otherwise specified.

RESUMEN

Myocardial infarction (MI) is the main cause of morbidity and mortality globally. This occurs due to occlusion of the coronary artery resulting in ischemia of the cardiac muscles. Typical symptoms include chest pain and discomfort. However, there are atypical symptoms including, but not limited to epigastric pain, nausea, and syncope. Such atypical symptoms upon presentation to the emergency department make it rather easy to overlook a potential MI. We present a case of a 70-year-old woman who had a delayed presentation to the emergency department with epigastric pain, nausea, and syncope. A nongated CT scan of the chest was utilized to rule out an aortic dissection. Interestingly, an unsuspected finding of a right coronary artery occlusion was detected instead. The patient underwent coronary artery stenting and was discharged a week later with a beta-blocker, dual antiplatelet therapy, a diuretic, and an anti-reflux medication. Overall, this case report emphasizes the importance of recognizing other atypical presentations in relation to MI. Additionally, this highlights the importance of the clinician's role in assessing the heart and coronary arteries when evaluating CT scans.

RESUMEN

The rare Dunbar syndrome or medial arcuate ligament syndrome (MALS) is defined as compression of the celiac trunk and/or ganglion by the medial arcuate ligament. It is often diagnosed after patients have suffered for a long time and is characterized by intermittent food-related pain, nausea, and unexplained weight loss. After exclusion of other causes of the above symptoms by gastroscopy, colonoscopy, CT, or MRI, the gold standard for diagnosis is dynamic color-coded duplex sonography, which may be supplemented by CT or MR angiography. The treatment of choice is a laparoscopic division of the arcuate ligament at the celiac trunk, although percutaneous transluminal angioplasty (PTA) with stent implantation may be performed in cases of postoperative persistence of symptoms or recurrent stenosis. Since symptoms persist postoperatively in up to 50% of cases, strict indication and complete diagnosis in designated centers are of great importance for successful treatment.

RESUMEN

BACKGROUND AND AIMS: Gastritis is a common histological diagnosis, although the prevalence is decreasing in developed populations, alongside decreasing prevalence of H. pylori infection. We sought to determine the prevalence of the etiology of gastritis in a Swedish population sample and to analyze any associations with symptoms, an area of clinical uncertainty. METHODS: Longitudinal population-based study based in Östhammar, Sweden. A randomly sampled adult population completed a validated gastrointestinal symptom questionnaire (Abdominal Symptom Questionnaire, ASQ) in 2011 (N = 1175). Participants < 80 years of age and who were eligible were invited to undergo esophagogastroduodenoscopy (EGD) (N = 947); 402 accepted and 368 underwent EGD with antral and body biopsies (average 54.1 years, range 20-79 years; 47.8% male) with H. pylori serology. RESULTS: Gastritis was found in 40.2% (148/368; 95% CI 35.2-45.2%). By rank, the most common histological subtype was reactive (68/148; 45.9%), then H. pylori (44/148; 29.7%), chronic non-H. pylori (29/148; 19.6%), and autoimmune (4/148; 2.7%). Gastritis was significantly associated with older age and H. pylori status (p < 0.01). Gastritis subjects were divided into three histological categories: chronic inactive inflammation, autoimmune gastritis, and active inflammation; there was no difference in the presence of upper gastrointestinal symptoms when categories were compared to cases with no pathological changes. Functional dyspepsia or gastroesophageal reflux were reported in 25.7% (38/148) of those with gastritis (any type or location) versus 34.1% (75/220) with no pathological changes (p = 0.32). Epigastric pain was more common in chronic H. pylori negative gastritis in the gastric body (OR = 3.22, 95% CI 1.08-9.62). CONCLUSION: Gastritis is common in the population with a prevalence of 40% and is usually asymptomatic. Chronic body gastritis may be associated with epigastric pain, but independent validation is required to confirm these findings. Clinicians should not generally ascribe symptoms to histological gastritis.

RESUMEN

Gastritis has recently been reported to be associated with nivolumab, and the clinical characteristics of nivolumab induced gastritis remain unclear. To explore the clinical characteristics of nivolumab induced gastritis, and to provide reference for the classification and treatment guidelines of immune checkpoint inhibitors -related gastritis. Case reports, case series, and clinical studies of nivolumab induced gastritis were retrospectively analyzed by searching the database from the establishment of the database until September 30, 2023. Forty-seven were included, with a median age of 57 years (range 16, 93). The median time of symptom onset was 6 months (range 0.5,36) and 6.5 cycles (range 2, 62). Nausea (29 cases, 61.7%), vomiting (29 cases, 61.7%), and epigastric pain (28 cases, 59.6%) were the most common complaints. Esophagogastroduodenoscopy mainly showed erythema (28 cases, 59.6%). Gastric mucosa biopsy showed epithelial inflammatory cell infiltration (22 cases, 46.8%) and apoptosis (15 cases, 31.9%). Most patients' symptoms and gastric mucosa improved or recovered after receiving systemic steroid and proton pump inhibitor therapy regardless of whether nivolumab was discontinued. Two patients died from gastritis related events. Gastritis should be considered as the cause of unexplained epigastric symptoms in the administration of nivolumab. Understanding the clinical features of nivolumab induced gastritis is very important for accurate diagnosis and timely management of these patients.
