Ischaemic necrosis of lesser curve of stomach after proximal gastric vagotomy.
Of 483 patients treated by proximal gastric vagotomy (PGV) between 1972 and 1986 four (0.8%) developed lesser curve necrosis with perforation and one died of diffuse peritonitis. Gastroscopy 3-6 days after PGV in 26 patients between November 1985 and May 1987 showed that five had developed ischemic ulcers on the lesser curve (19%). One further patient developed lesser curve necrosis with perforation before endoscopy, giving a total of six lesser curve lesions after 26 vagotomies (23%). Endoscopy also showed that most patients had some gastric retention. Ulcers with maximal diameters of 0.4-2 cm were asymptomatic. One patient with a large ischaemic ulcer (3 cm) had an abrupt fall in haemoglobin concentration (from 148 to 73 g/l) as did two patients who developed lesser curve necrosis with perforation and peritonitis (143 to 93, and 159 to 71, respectively). We conclude that ischemic ulcers are relatively common after PGV, that small ulcers are asymptomatic and do not perforate, and that an upper GI bleeding after PGV strongly suggests that lesser curve necrosis has developed.
