RESUMEN

Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is an uncommon disorder that involves a set of symptoms that primarily includes postprandial pain at times associated with intestinal obstruction. Although a rare disease in the general population, SMA syndrome has a high probability of occurrence in patients who are severely malnourished or have certain debilitating conditions leading to a loss of retroperitoneal fat. Here, we present the case of a 16-year-old male with a one-year history of postprandial abdominal pain associated with nausea, multiple episodes of vomiting, and abdominal distension. Amid a delayed diagnosis and multiple hospital visits, the patient's condition further deteriorated. Thereafter, computed tomography of the abdomen confirmed this rare diagnosis. Because the patient could not be further managed conservatively, laparoscopic duodenojejunostomy was planned and done. This case report highlights the various challenges in diagnosing this disease and highlights the importance of an early diagnosis so that patients can be managed effectively and timely.

RESUMEN

Background: The selection of patients with MALS for surgical treatment depends upon the reliability of the symptom interpretation and the diagnostic work-up. We aimed to follow up the results of the laparoscopic decompression of the patients with MALS. Patients and Methods: In a single-center, 52 consecutive MALS patients were followed-up, prospectively, after transperitoneal laparoscopic decompression. MALS was diagnosed with a computed tomography angiography (CTA) verified stenosis, ≥50% of the celiac artery (CA), and with duplex ultrasound, a peak systolic velocity (PSV) ≥2.0 m/s. Postoperative, CTA, and duplex ultrasound were performed, and the patients were followed-up at 3, 6, 12 months, and yearly after that. Results: Mean age of the patients was 47 ±21 years, and 65% were females. The patients had a mean weight loss of 8.4 ±7.2 kg. Fifty-one patients had the laparoscopic operation with a mean operation time of 102 ± 28 minutes. Forty-seven patients (90%) achieved relief from the symptoms either completely (67%) or partially (23%) at 3-6 months of follow-up. Significant improvement in postoperative PSV was found compared to the preoperative values, p<0.001. Five patients (10%) with no immediate effect of the operation, but two of them became free from symptoms during the mean study follow-up of 2.4 ± 2 years. Five patients (10%) had operative complications, including one trocar injury to the liver, one pneumothorax, and three cases of bleeding from the branches of CA. Two patients died of cancer disease during the study period. Only two patients (4%) had symptoms relapse, both later treated successfully. Conclusion: Laparoscopic transperitoneal decompression provides most of the patients a persistent relief from MALS symptoms.

RESUMEN

The European Society for Neurogastroenterology and Motility's (ESNM) consensus document on functional dyspepsia (FD) has provided a critical review of the evidence for 36 statements highly relevant to the diagnosis and treatment of FD. We provide here our expert opinion on the North American, Australian and Asian assessments of the same topics discussed, and provide evidence where the ESNM consensus may deviate from those in the other continents. New and exciting data about the pathogenesis of FD are emerging including the possible central role of duodenal micro-inflammation (most notably eosinophilic duodenitis and intestinal mast cell disease), but this is a very dynamic field with several gaps remaining in our understanding that are summarized in this review. Identification of non-invasive biomarkers and testing of targeted therapies, including assessing the benefits of multidisciplinary teams in the management of FD, should be future priorities.

RESUMEN

INTRODUCTION: Median arcuate ligament or Dunbar syndrome is a rare vascular disorder causing celiac trunk stenosis or occlusion due to the extrinsic compression by the median arcuate ligament. A visceral aneurysm may develop as a complication. PATIENTS AND METHODS: We experienced an inferior pancreaticoduodenal artery aneurysm presentation in two female patients with the median arcuate syndrome previously diagnosed. One patient presented with postprandial abdominal pain and weight loss and the other one was asymptomatic. RESULTS: We described our experience with the both patients being successfully treated surgically. CONCLUSIONS: Awareness of possible repercussions of the celiac trunk stenosis to peripancreatic arteries should be elevated. Restoration of physiological blood flow by removing pathologic anatomy should be performed. Since there is no correlation between the size of a visceral aneurysm and the risk of rupture, having a high postrupture mortality, pancreaticoduodenal artery aneurysms should be treated even if asymptomatic. Surgical treatment remains the mainstay treatment of the Dunbar syndrome complicated by visceral aneurysms.

RESUMEN

BACKGROUND & AIMS: Functional dyspepsia (FD) is subdivided into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS) according to the Rome III consensus. In clinical practice, there is a major overlap between these subgroups. The Rome IV criteria included postprandially occurring symptoms in the PDS subgroup. We aimed to analyze the effects of the Rome IV criteria, compared with Rome III, on FD subgroups in patients recruited from secondary care. METHODS: Patients with FD (n = 224; mean age, 43 ± 1 y; 77% women) were recruited from secondary-care units in Belgium and filled out symptom questionnaires, allowing subdivision according to Rome III and Rome IV criteria and identification of postprandial symptoms. Symptom patterns and demographics were compared between the subgroups. Statistical analysis was performed using the t test and the Fisher exact test. RESULTS: According to the Rome III criteria, 25% of participants had PDS, 8% had EPS, and 67% had an overlap. Postprandial fullness, early satiation, and bloating were present in significantly more patients in the PDS and overlap groups than the EPS group (P < .0001). A higher proportion of patients in the overlap group showed symptoms such as postprandial epigastric pain and nausea than in the EPS group (both P ≤ .02). With the Rome IV criteria, the overlap group was reduced to 35%; 57% of patients were considered to have PDS and 8% to have EPS. Postprandial pain was significantly more prevalent in the PDS than in the EPS group (P ≤ .002), and postprandial nausea was significantly more prevalent in the PDS group than the overlap group (P = .007). CONCLUSIONS: Compared with Rome III criteria, the Rome IV criteria significantly reduces the overlap between PDS and EPS groups. Studies are needed to determine if Rome IV subgroups are associated differently with psychological comorbidities and treatment responses.

RESUMEN

Chronic mesenteric ischemia (CMI) is a condition defined by a state of attenuated blood circulation in the mesenteric vasculature affecting one or more abdominal viscera, and is more common in the female and elderly populations. Amongst the many causes, it occurs most frequently in connection with diffuse atherosclerosis. Its presentation is variable with symptoms such as weight loss, nausea, vomiting, diarrhea and/or constipation, with postprandial pain classically present in the majority of the cases; this, in addition to the chronic course of the disease, makes timely diagnosis a challenge. Physical examination may reveal signs of malnutrition and other findings usually linked with the underlying medical condition. It can have grave consequences if not managed promptly. In our case, an 81-year-old woman came in with loss of appetite, nausea, vomiting, diarrhea and/or constipation, and weight loss. Computed tomography angiography (CTA) of the abdomen/pelvis confirmed chronic occlusion of the mesenteric vessels. She was treated surgically. This discussion is based on chronic mesenteric ischemia and its nonspecific symptomatology, particularly its association with weight loss.

RESUMEN

Wilkie's syndrome, also commonly known as superior mesenteric artery (SMA) syndrome, is an infrequent and rare cause of small bowel obstruction. It is caused by extrinsic compression of the duodenal segment of the intestine between the aorta and SMA, causing significant post-prandial abdominal pain and vomiting. The literature suggests the incidence of 0.01% to 0.3%. We present here an atypical presentation of SMA syndrome in which a young patient presented to our tertiary set-up with unusually constant abdominal pain and weight loss requiring invasive interventions.

RESUMEN

Median arcuate ligament syndrome (MALS), also known as celiac artery compression syndrome (CACS), is a rare clinical entity that is characterized by extrinsic compression of the celiac artery by the median arcuate ligament of the diaphragm. It mostly presents as a triad of post-prandial abdominal pain, weight loss, and bruit in the epigastrium. Given its variable and atypical presentation, it is a diagnostic challenge for physicians. MALS is supposed to be a diagnosis of exclusion and, thus, many investigations need to be done before coining it as a definitive diagnosis. Herein, we present a case of a 17-year-old female patient, a known case of common variable immunodeficiency (CVID) who presented to our setup with progressive, excruciating epigastric pain and bilious vomiting after undergoing excision of CVID-associated gastric adenocarcinoma (CAGA). Multiple sets of tests were conducted to rule out possible cardiopulmonary, musculoskeletal, and abdominal etiology. The diagnosis was made on the basis of findings depicted on three-dimensional computed tomographic angiography (3D-CTA) and ultrasound Doppler studies of the celiac artery. She underwent laparoscopic dissection of the median arcuate ligament with a celiac plexus block, which yielded immediate relief in symptomatology and was later followed up with duplex scans and showed complete remission of symptoms.

RESUMEN

This case report describes an atypical and unique presentation of mesenteric arteries occlusive disease. The patient presented with typical symptoms of chronic mesenteric ischemia, as well as with an atypical new symptom; postprandial buttock and lower limbs pain. Pain followed the time curve of the postprandial abdominal discomfort, starting 30 min after meals and gradually resolving within 2 h. The patient had been tolerating the signs of chronic mesenteric ischemia quite well by adjusting the quantity of food per meal to relieve symptoms. Angiography showed that the celiac artery, the superior mesenteric artery, and distal aorta were occluded, leaving the inferior mesenteric artery as the only feeding vessel of all abdominal viscera and both the lower limbs. Since an English medical literature search returned only one marginally similar case, we consider this case of iliac arteries' "steal syndrome" from the inferior mesenteric artery unique.

RESUMEN

A 63 year old female presented to the emergency department with a several month history of intermittent right upper quadrant abdominal pain, early satiety with loss of appetite, and an unintentional weight loss of 8. She underwent a battery of tests that returned negative and subsequently sent for Computed tomographic angiography (CTA) of the abdomen revealing luminal stenosis of the proximal 1 cm of the celiac axis estimating 90% occlusion and a patent SMA and IMA with, typical for median arcuate ligament syndrome. The symptoms, diagnosis, and treatment options are discussed.
