Ambulatory hernia surgery

Ambulatory hernia surgeryIn the United States ambulatory hernia surgery became a fact of life when Medicare, the federal programme that reimburses hospitals and physicians for medical care of the elderly, finally followed the lead of other third party payers and disallowed reimbursement for hospitalization of those over 65 years old undergoing elective inguinal hernioplasty.This dictate was less Draconian than it first appeared because nearly all groin hernioplasties were already being performed preferentially on a day-patient basis.This timely method of performing inguinal hernioplasty benefits everyone.It is safe, convenient, efficient, economical and very popular.Furthermore, the mere idea of ambulatory hernia surgery softens the emotional impact of the operation and thereby reduces disability by encouraging the patient to get on with his life.In the beginning, financial incentives were necessary to promote acceptance.However, it soon became obvious that the majority of the patients preferred not to be admitted as in-patients.Making ambulatory hernia surgery easy and unintrusive for the patient is primarily the responsibility of the surgeon.Of course, ambulatory units must be user-friendly, but in the end how the patient 'does', as measured by disability, morbidity, and chance of recurrence depends almost solely on the technical skills of the surgeon, the hernioplasty employed, the mode of anaesthesia and attention to minute details.These important matters for concern have been largely overlooked.They need addressing for they define good surgery.Ambulatory hernia surgery does not preclude general, spinal or epidural anaesthesia.However, the perfect anaesthesia for a primary, reducible inguinal hernia in the non-obese is local anaesthesia.In routine cases, the assistance of an anaesthetist is usually not necessary and only adds to the cost.Furthermore, local anaesthesia eliminates the need for costly preoperative testing.Informed patients actually prefer local to general anaesthesia and like to have the operation without missing their morning cup of coffee.Surgeons ought to like local anaesthesia because it shortens the time between cases and challenges their technical ability.Local anaesthesia is safe, and furthermore it allows immediate ambulation and early discharge from the ambulatory unit.Much has been written about the technique of administering the anaesthetic.However, the comfort of the patient has more to do with the surgeon's ability to operate gently and to dissect sharply than it has to do with his technical skills with a syringe and needle filled with local anaesthetic.The burning pain caused by the administration of the local anaesthetic can be eliminated by neutralizing the agent.This also greatly enhances the anaesthesia and reduces the quantity of anaesthetic required.The 8.4 per cent sodium bicarbonate solution from the operating room emergency tray may be used if vials of small quantity are not available.The pH of plain local anaesthetic is about 6.0, and simply drawing l m l of the sodium bicarbonate solution into a 10 ml syringe filled with 9 mi of plain local anaesthetic brings the pH to a comfortable value of about 7.5.The pH of local anaesthetic with adrenaline is about 4.0 and therefore 2.5 ml of the sodium bicarbonate solution are required.The selection of the hernioplasty is important.If other things are equal, the hernioplasty producing the least disability ought to be the procedure of choice.The hernioplasty with the reputation for the shortest convalescence is the Shouldice hernioplasty.In fact, it was E. E. Shouldice who, more than 45 years ago, pioneered short stay hernioplasty and thus paved the way for day hernia surgery.He held the view, long before other surgeons concurred, that patients could not wilfully hurt themselves.Acting accordingly, he discharged his patients after a couple of days and encouraged them to resume all physical activities as soon as their discomfort permitted.This attitude, coupled with a low chance of recurrence, brought many thousands of patients to his Toronto clinic.The hernioplasty developed at his hospital by co-workers Obney and Ryan actually complements this attitude.The Shouldice hernioplasty's good results have been confirmed by many and are attributable to the use of continuous sutures which distribute tension evenly, to the imbrication of the structurally important innermost aponeurotic-fascia1 layer resulting in a strong seam, and to a repair which is essentially tension freel-j.The operation is easy and is a joy to perform.What remains astounding is how many surgeons still disbelieve the good results and stubbornly adhere to techniques which do not match the Shouldice hernioplasty and are less well suited for day surgery.Most patients with bilateral hernias can have them repaired at the same time provided that the hernias are not too large and that the time for the awake patient on the uncomfortable operating room table is not too long.There is no advantage in separating the procedures and patients are disappointed at the thought of two separate periods of disability.Surprisingly, the disability from bilateral hernioplasties is not essentially different from that of unilateral hernioplasty.However, a prudent surgeon would delay repair of a second indirect hernia if for any reason the indirect sac of the first side had to be completely dissected from the cord.This occurs with sliding indirect inguinal hernia sacs.Morbidity prolongs convalescence and disappoints patients.However, the belief that 1228
