One hundred and two patients with a pilonidal sinus treated by minor excision had a life-table of 5-year freedom from recurrence of 89% provided that they attended a dressing clinic until the wound healed. With failure to attend the clinic, the recurrence freedom fell to 57% (P less than 0.004). Age, sex, acute abscess, previous excision, presence of hairs and the number of midline pits and lateral abscesses did not significantly influence the result. The method supersedes more extensive procedures, but should be tested against even less traumatic techniques.
Hiatal herniation caused by contraction of the longitudinal muscle of the oesophagus has been prevented by disconnecting the local vagal nerve supply while preserving the vagal connections to more distant organs. A selective oesophageal vagotomy above the lung hilum may prove an effective adjunct to orthodox hiatal hernia repair in man.

From a study of the organization of a national clinical trial on the management of early cancer of the breast in women there appear to be overwhelming advantages in studying large numbers of patients. To this end centres abroad have been encouraged to join. All the evidence at present suggests that it is feasible to organize a study on this scale, that the documentation and follow-up are accurate, and that the enthusiasm of the participants can be successfully fostered and maintained.
