Enucleation of a giant symptomatic gastric lipoma, a safe surgical approach

Gastric lipomas are rare, representing 2–3% of all benign tumours of the stomach. Most of these stomach neoplasms are small and detected incidentally during endoscopic or radiology evaluations. Computed tomography is highly specific imaging for lipoma diagnosis. Endoscopy and endoscopic ultrasound are other important diagnostic modalities to confirm the diagnosis. Identifying typical features can avoid biopsy or surgery in asymptomatic patients. In patients with larger lesions, usually more than 2 cm, clinical presentation may encompass haemorrhage, abdominal pain, pyloric obstruction and dyspepsia. As a result of its extreme low incidence, treatment is not standardized, though it is widely accepted that a symptomatic tumour mandates resection. Here, we present the case of a 60-year-old female presenting with abdominal pain and recurrent vomiting due to a giant gastric lipoma (80 × 35 × 35 mm). The patient underwent laparotomy and an enucleation was performed.

Analysis of risk factors and prevention strategies for functional delayed gastric emptying in 1243 patients with distal gastric cancer

Background Analysis of the risk factors associated with functional delayed gastric emptying after distal gastric cancer surgery to provide a basis for further reduction of the incidence of this complication. Methods Total of 1382 patients with distal gastric cancer from January 2016 to October 2018 were enrolled. Correlation analysis was performed in 53 patients with FDGE by logistic regression. Subgroup risk analysis was performed in 114 patients with preoperative pyloric obstruction. A Pearson Chi-square analysis was used to compare categorical variables between normal distribution groups. Meanwhile, a t test was used to compare continuous variables between groups. Odds ratio (OR) was used for comparison of the two groups, and it was summarized with its 95% confidence interval (CI) and p value using logistic regression. Result In multivariable analysis, age (OR 1.081, 95% CI, 1.047–1.117), BMI (OR 1.233, 95% CI, 1.116–1.363), preoperative pyloric obstruction (OR 3.831, 95% CI, 1.829–8.023), smaller volume of residual stomach (OR 1.838, 95% CI, 1.325–6.080), and anastomosis in greater curvature perpendicular (OR 3.385, 95% CI, 1.632–7.019) and in greater curvature parallel (OR 2.375, 95% CI, 0.963–5.861) were independent risk factors of FDGE. In the preoperative pyloric obstruction group, higher BMI (OR 1.309, 95% CI, 1.086–1.579) and preoperative obstruction time (OR 1.054, 95% CI, 1.003–1.108) were independent risk factors of FDGE and preoperative gastrointestinal decompression (OR 0.231, 95% CI, 0.068–0.785) was independent protective factor of FDGE. Conclusion Adequate gastrointestinal decompression should be performed before the operation to reduce the incidence of postoperative gastroparesis in patients with preoperative pyloric obstruction. We also could improve the surgical methods to reduce the occurrence of FDGE, such as controlling the size of the residual stomach, ensuring blood supply. Especially selecting an appropriate stapler and anastomosis during the anastomosis process, the occurrence of FDGE can be reduced.

Application of Nutritional Support in the Comprehensive Treatment of Gastric Cancer: A Case Report

Objective To relieve long-term malnutrition caused by a malignant tumor affecting the pylorus and to prolong the patient survival. Methods A patient presented with complete pyloric obstruction due to pyloric tumors, and achieved good therapeutic effects through nutritional support and effective chemotherapy. Results After about 40 days of treatment, all physiological indicators were improving. After chemotherapy, the pyloric tumor shrank and the complete obstruction was relieved. The patient was able to eat and drink normally. Conclusion Nutritional support, combined with chemotherapy, may effectively treat complete pyloric obstruction caused by advanced tumors.

Endoscopic Balloon Dilatation for Incomplete Pyloromyotomy – a case report.

Introduction: This is a report of immediate endoscopic balloon dilatation for incomplete pyloromyotomy in idiopathic hypertrophic pyloric stenosis. Case Report: A two month-old boy presented with 6 weeks of projectile vomiting, failure to thrive and severe physiologic disturbance. Following investigation and resuscitation he underwent laparoscopic pyloromyotomy. Recovery was delayed due to ongoing projectile vomiting. Contrast studies showed persisting proximal pyloric obstruction. On the third post-operative day, endoscopic balloon dilatation of the residual proximal pyloric stenosis was successful, with immediate tolerance of feeds. Discussion: We describe the presenting features of his case, the technical details of our management and a review of the relevant literature.

Patient-generated subjective global assessment versus nutritional risk screening 2002 for gastric cancer in Chinese patients

Aim: Patient-Generated Subjective Global Assessment (PG-SGA) and Nutritional Risk Screening 2002 (NRS2002) are used to evaluate patients’ nutritional status. Materials & methods: The data of 114 gastric cancer patients with pyloric obstruction treated between July 2016 and July 2017 were assessed retrospectively. Results: Based on clinical evaluation, 70.1% had malnutrition, with 61.4% at nutritional risk by NRS2002 and 66.7% by PG-SGA. The area under the receiver operating characteristic curve was 0.858 for PG-SGA and 0.706 for NRS2002. Sensitivity and specificity were 89 and 85% for PG-SGA and 78 and 76% for NRS2002. In both assessments, patients at risk showed more postoperative complications. Conclusion: PG-SGA was more suitable for evaluating the preoperative nutritional status of gastric cancer patients with pyloric obstruction, with higher diagnostic efficacy.

Pyloric stenosis as a manifestation of isolated gastric Crohn’s disease responding to intralesional steroid injection and balloon dilation: a case report

Background Crohn’s disease is a chronic inflammatory condition that can affect the gut from mouth to anus. Gastroduodenal involvement is seen in less than 5% of all patients with Crohn’s disease. Among those cases, isolated gastric Crohn’s disease is even rarer. Although most patients with isolated gastric involvement have nonspecific complaints, very few of them do develop features of pyloric obstruction. There is a paucity of data on specific management of gastric Crohn’s disease owing to its rarity and its frequent coexistence with colonic or ileal disease. We report a case of a patient who had pyloric stenosis as a manifestation of isolated gastric Crohn’s disease responding to intralesional steroid injection and balloon dilation. Case presentation A previously healthy woman presented with recurrent postprandial vomiting, epigastric discomfort, and unintentional weight loss over 6 months. She had no diarrhea or extraintestinal manifestations. Clinically, she was pale and dehydrated. Examination of systems was unremarkable except for mild epigastric tenderness. Her initial laboratory findings were normocytic normochromic anemia, high inflammatory markers, and hypokalemia. Esophagogastroduodenoscopy revealed an inflamed pyloric mucosa with features of pyloric obstruction. Furthermore, magnetic resonance enterography confirmed the pyloric stenosis. Histopathological examination of a biopsy from the pylorus revealed noncaseating granuloma with superficial ulceration. Tuberculosis and sarcoidosis were excluded by appropriate investigations, and a diagnosis of gastric Crohn’s disease was made. Following the initial resuscitation, intralesional steroid injection and controlled radial expansion balloon dilation of the pylorus were carried out. The patient was commenced on azathioprine as a maintenance treatment, which led to a successful dilation and remarkable symptom improvement. Conclusion Symptoms of pyloric obstruction as a manifestation of isolated gastric Crohn’s disease are extremely unusual in clinical practice, awareness of which would facilitate early appropriate investigations and treatment.
