Variation in Size of the Gastric Antrum

Indications for Conservative Surgery in Gastric Ulcer

“…Most gastric ulcers occur at the junction of antral and fundic mucosa (Oi et al , 1959; Marks and Shay, 1959; Shrager et al , 1967), the level of which varies in different individuals (Dean and Mason, 1964; Capper et al , 1966). The coexistence of high gastric ulcers with a high antro‐fundic junction is supported by evidence that these ulcers are associated with a small parietal cell mass (Baron, 1963) and a large area of atrophic antral mucosa (Du Plessis, 1965; Capper et al , 1966). Thus a high ulcer is often accompanied by achlorhydria (Johnson, 1965; Vesely et al , 1968), while low gastric and duodenal ulcers commonly occur in patients with high gastric acid levels.…”

“…They have further shown that nearly all peptic ulcers occur at a point where the mucosal junction coincides with muscular areas subjected to intensified local strain and in‐creased mobility (Oi et al , 1969). Most gastric ulcers occur at the junction of antral and fundic mucosa (Oi et al , 1959; Marks and Shay, 1959; Shrager et al , 1967), the level of which varies in different individuals (Dean and Mason, 1964; Capper et al , 1966). The coexistence of high gastric ulcers with a high antro‐fundic junction is supported by evidence that these ulcers are associated with a small parietal cell mass (Baron, 1963) and a large area of atrophic antral mucosa (Du Plessis, 1965; Capper et al , 1966).…”

Alkaline areas in gastric mucosa after gastric surgery

“…In each case the gastric remnant was opened at operation and the pH of the mucosa was recorded during continuous histamine stimulation (Capper et al, 1962).…”

“…The variations in size of the alkaline area of the gastric mucosa in disorders such as gastric ulcer, duodenal ulcer, and combined gastric and duodenal ulcer have been reported previously (Capper, Laidlaw, Buckler, and Richards, 1962;Capper, Butler, Buckler, and Hallett, 1966). The areas were defined at operation using a pH monitoring system, and were confirmed histologically afterwards.…”

Precise antrectomy

“…The border has no fixed position but moves towards the cardia with increasing age, especially on the lesser curvature side [4]. In general, the antrum is large in patients with gastric ulcer [3], but there are important individual variations [3,5]. It is unclear whether the reduction of the fundic area caused by this movement of the border is accompanied by a corresponding increase in the functional pyloric mucosa, meaning the gastrin cell (G cell)-containing mucosa.…”
