A case is reported of a 55 year old male patient with primary hypertrophic pyloric stenosis who was subjected to distal gastrectomy. Adult hypertrophic pyloric stenosis is an uncommon condition which is usually misdiagnosed as carcinoma of the antrum. It is a benign disease resulting from hypertrophy of the circular fibres of the pyloric canal and is recognizable radiologically by narrowing and elongation of the pyloric canal and endoscopically by appearances resembling those of the cervix. This condition is probably congenital although aetiology has not been established. In the absence of symptoms, no clinical treatment is required. However, surgical intervention is advocated, when stenosis gives rise to symptoms, there is a suspicion of malignancy, or the ulceration due to the disease. Distal gastrectomy with gastroduodenostomy is the treatment of choice.

A rare case of branch retinal artery occlusion (BRAO) following a subtotal thyroidectomy for thyroid cancer in a 58-year-old woman is reported herein. Five days after her thyroidectomy, the patient complained of having had a reduction in visual acuity and visual field loss of the superior nasal side in her right eye since the operation. BRAO was diagnosed following the discovery by funduscopy of inferotemporal branch artery occlusion with retinal edema, hemorrhage, and periarterial sheathing in the right eye. Despite immediately puncturing the anterior camera and massaging the eyeball while administering intravenous anticoagulant therapy, the visual field disturbance remained unchanged. The most common causative factor of postoperative sudden BRAO is reported to be emboli. However, in our case, the most likely cause was the stretching and pressure exerted on the carotid artery with consequent atheromatous plaque formation at the time of thyroidectomy.
