This operation consists in dissecting the posterior rec­tal wall throught the internal fistulous opening to a depth of 1 cm (Fig. 88,1). The suppurative cavity com­municating with the rectal opening, is curetted with a sharp spoon Fig. 88,2) and painted with 2% iodine tinc­ture. The rectal wiund and the remaining pirtion of the cavity are packed with a wick heavily coaked with oint ment. Should any doubt arise as to the subsequent func­tion of the sphincter, we recimmend that catgut suture be placed on the wound bottom (Fig. 88,3; see also Figs 75,1 and 75,2). The care of the wound is as usual. Packing is discontinued in 5 days. In those cases of incomplete internal fistula, when a deep cavity remains on the pos­terior rectal wall following dissection of a subsidiary suppurating cavity from the rectal side, we pack it daily during dressings by applying a narrow ointment-soaked wick rolled into a ball, which is tucked into this cavity with a finger (Fig. 88,4). Opium tincture is given for 7—9 days, and may be continue! for 4 days more when dressings are applied. During daily dressings the cavity in the rectum is washed, after removal of the wick, with an antibiotic solution by means of a syringe fitted with a thick blunt curved needle, and then again packed with an ointment wick.
