The use of circular staplers for the treatment of haemorrhoids is a new technique that makes for better correction of the physiopathology of the condition, affords greater patient comfort and reduces health-care expenditure. This technique, which was invented by A. Longo in 1993, pulls up the haemorrhoidal cushions into their anatomical position, reduces or avoids postoperative pain, sparing the sensitive fibres of the anal canal, avoids anal canal stenosis and is not complicated by faecal incontinence. The authors present their experience in 41 patients affected by symptomatic haemorrhoidal prolapse and treated with a mucosal rectal prolapsectomy using a circular stapler. Each patient was followed up for 6 months to assess the incidence of complications and the degree of patient satisfaction. The results were compared with those reported in the literature, obtained using the Milligan-Morgan procedure. The Longo technique, which can be performed in the one-day surgery setting, allows very good relief of postoperative pain, rapid functional recovery and an early return to work, with a saving in health-care expenditure as compared with conventional treatment.
