Combined endoscopic and laparoscopic approach for palliative resection of metastatic melanoma of the stomach
BACKGROUND: Metastatic tumours of the stomach present a clinical dilemma for the surgeon. Palliative surgical resection can alleviate symptoms and prolong survival in selected patients. However, previous studies have used open methods of surgical resection with potentially high morbidity and mortality. We describe the use of laparoscopic wedge resection of the stomach for palliative resection of metastatic melanoma to highlight the benefits of this technique. CASE PRESENTATION: A 58 year old male was investigated for iron deficiency anaemia while under treatment for pulmonary metastatic malignant melanoma. An upper gastrointestinal endoscopy revealed a 5 cm diameter ulcer on the anterior wall of the stomach, biopsies from the ulcer confirmed metastatic melanoma. Laparoscopic wedge resection of the stomach lesion was performed without complication. CONCLUSION: Laparoscopic approach has many benefits and is useful for the palliative resection of rare tumours of the stomach in order to preserve the quality of life. Its use should be considered in selected patients

Does domperidone, a D2-antagonist alter gastric emptying rates and appetite sensations in healthy adults with high-fat meal? A block-randomised, single-blind placebo-controlled study
BACKGROUND: Accelerated gastric emptying (GE) may lead to reduced satiation, increased food intake and is associated with obesity and type 2 diabetes. Domperidone is a dopamine 2 (D(2)) receptor antagonist with claims of gastrointestinal tract pro-kinetic activity. In humans, domperidone is used as an anti-emetic and treatment for gastrointestinal bloating and discomfort.
AIM: To determine the effect of acute domperidone administration on GE rate and appetite sensations in healthy adults.
METHODS: A single-blind block randomised placebo-controlled crossover study assessed 13 healthy adults. Subjects ingested 10 mg domperidone or placebo 30 min before a high-fat (HF) test meal. GE rate was determined using the (13)CO(2) octanoic acid breath test. Breath samples and subjective appetite ratings were collected in the fasted and during the 360 min postprandial period.
RESULTS:Gastric emptying half-time was similar following placebo (254 ± 54 min) and 10 mg domperidone (236 ± 65 min). Domperidone did not change appetite sensations during the 360 min postprandial period (P > 0.05).
CONCLUSIONS: In healthy adults, acute administration of 10 mg domperidone did not change GE or appetite sensations following a HF test meal
