D. {Reprinted from the Montreal Medical Journal, June, 1893.) '^v.. P"^ A SECOND SERIES OF CASES OF SKIN TRANS- PLANTATION BY THIERSCH'S METilOD.* By Jav.es Bell, M.D. Surgeon to the Montreal General Hjspital ; Associate Professor of Clinical SurKery MoQill University. In December, 1887, just five years ago, I read a paper be- fore this Society entitled, " The Treatment of Ulcers by the Transplantation of Large Pieces of Skin after Thier.^ck's Method" I then described the operation in considerable detail and gave full clinical reports of the first six cases on which I had operated, — (the patients were also presented for examina- tion) . To-night I venture to offer some further observations upon this operation, based upon th. reports of thirty-six cases operated upon in the hospital 'lince that time. These cases are taken from the hospital books, and this series includes only those in which an operation was definitely undertaken for the purpose of healing a wound or ulcer. Minor cases in which the area to be covered was estimated at less than two square inches, and all those cases in which skin was transplanted in the course of another operation, as in the removal of small can- cerous or lupoid ulcers from the face, webbed fingers, plastic operations, etc., are not included. Case 31 is an exception to the first part of this statement and was included here on account of the great age of the patient (71 years). The area to be covered for chronic ulcer in this case was about one and a half square inches. , Age — In age the patients range, as will be seen from the ♦ Read before the Montreal Medico-Chirurgioal Society, Dec. 23, 1892. mit^^ 8 ; appended tabulated statement, from 10 to 74 years, there being six patients under 30, five of whom were operated upon for ulceration due to burns, and one for ulcerations caused by a machinery accident, seven patients between 30 and 40, two of them due to burns, seven between 50 and 60, eight over 60, and three whose ages are not noted, bui all of whom were over 40 and operated upon for chronic ulcer. Lesions — Twenty-five patients were operated upon for chronic ulcers of the legs, in six of whom both legs were operated upon at the same time. Two were operated upon for acute ulceration of the arms following burns i.e., within a few months of the acci- dent ; one for extensive burns of the face, neck, hands and arms, three for chronic ulcers following burns, i.e., ulcers which for months or years ha I ceased to make any progress towards healing, and three for contracted keloid cicatrices following burns. These cicatrices were dissected away and skin transplanted. Ona was in the axilla binding the arm to the side, one in the poplitdal space flexing the leg to a right angle, and one in the lower part of the face and neck flexing the chin upon the breast and everting the lower lip. The first two of these were operated upon in two stages, that is, the scar first removed and the limb replaced in its normal position of exten- sion, and the skin transplanted some weeks later, when the deep irregular spaces had become filled up with granulation tissue. Of the two remaining cases, one was operated upon for destruction of skin, muscle and periosteum of tibia by machinery, and one was transplanted after removal of a large epithelioma- tous ulcer of the leg. Results — In thirty-three of the thirty-six cases here reported the ulcers were completely healed — that is, covered with a good, sound skin in three weeks after operation. The three cases, 28, 33 and 36, in the appended table in which healing was not completed in three weeks will be referred to individually later on. In th« criticisms which followed the reading of my first paper on this subject, the opinion was expressed that the skin thus re- produced would not last, but that the old areas of ulceration ^ ' 4 would soon be in the same condition as before operation. I could not then answer this objection from personal experience, but I can now say most emphatically that such is not the case. In proof of this statement I have here to-night the first patient on whom I operated in August, 1887. On three different occasions since the operation he has developed small ulcers upon the same leg, which absolutely refused to heal until they were scraped and skin grafted upon them. In every instance, moreover, the ulcer appeared, not upon the skin which had been transplanted and which remained perfectly normal, but just outside the border of the transplanted area. Three cases of this series (2, :^2 and 25) returned for operation a second time. In all three the ulceration had begun in the ol(f skin outside the originally transplanted area and at the time of operation in each case more than half of the originally trans- planted skin remained sound, while extensive ulceration had occurred outside its border. Cases 2 and 3 were first trans- planted from an amputated leg, the operation beginning in the first one hour and in the second two hours after the removal of the limb ; no result. Case 2 of my first series was a profes- sional beggar and returned to the hospital since I reported his case with ulceration of his leg, which, like the preceding cases, was much more extensive in the surrounding skin than in the previously transplanted area. He declined to have his leg operated upon a second time, as he depended upon this ulcer- ated condition to secure him his livelihood from a sympathetic public. Case 28 was that of a man aged 41 who came to hospital twenty-nine days after having been burnt with ignited varnish. His whole face, neck, forearms and hands were ex- tensively and in places deeply burnt. He was delirious and very ill (thought to be suffering from iodoform intoxication). One eye was destroyed and the other seriously damaged. On this account Dr. Buller was associated with me in the treatment of the case. Seven weeks after admission I proceeded to transplant skin, and in order to give Dr. Buller an opportunity to complete the treatment of the eye, I transplanted skin from the patient's thighs to his forearms and hands, while Dr. Buller transplanted ^— p 6 1 i a small area in the itnmediato vicinity of the eye. In three weeks the parts transplanted were completely covered with skin ; a normal result. As I had at the first operation pretty well denuded his emaciated thighs and calves, and the face and neck were still to be dealt with (with the exception of the limited area around the eye transplanted by Dr. Buller), 1 advised the patient to secure some person who would allow the skin to be taken from his thighs and transplanted to the patient's face. As he was a private patient and able to pay he adopted my suggestion, and four weeks later the face and neck were trans- planted with skin in this way. The young man from whom the skin had been taken was sent into the ward to allow of the healing of the thighs, when it was found that he was very ill and feverish. He had only been cursorily examined and had not been under observation at all before the operation. Further examination showed that he was in the second week of typhoid fever, from which he recovered after a very severe illness. My patient in the meantime became ill and feverish, and the skin which had been transplanted necrosed and separated within ten days, and considerable areas of ulceration again appeared upon the hands which had been perfectly healed. Some weeks later another man was secured and skin transplanted again. The final result, especially as far as the face was concerned, was not perfectly satisfactory, as the skin only took in places and a great deal of contraction followed. In this connection it is in- teresting to note that Herr Sick, first assistant in Schede's Klinik, Hamburg, records a case (Centralblat fur Chirurgie, No. 44, 1892), in which skin transplanted to the head of a ten-year-old girl from the thighs of two healthy young men, healed com- pletely, but in the course of three weeks it broke down and as completely disappeared. A second attempt to cover the defect with skin from a sister of the patient of about the same age was unsuccessful, and only at the third operation, when the skin was taken from the patient herself, was the operation successful. Case 35, operated upon two weeks ago and still in hospital, is that of a ten year old girl suffering from contraction of the chin upon the chest and great eversion of the lower lip by ..■!:. 6 cicatricial tissue, the result of a burn. Only a little more than half of the skin transplanted has taken in this case. The im- perfect results in these two cases I attribute to the great diffi- culty in dressing the wound in this situation (the face), so as to retain the strips of skin in position and maintain asepsis, — in fact the latter is impossible in the immediate neighborhood of the mouth and nostrils. Case 33, a feeble old man aged 65, with very weak circula- tion and suffering from asthmatic attacks, was operated upon November 18th, 1892. He had suffered from a chronic ulcer for thirty years, but about July last it became painful and began to grow hard about the edges. On admission to hospital the hard nodulea about the edges were examined microscopi- cally and pronounced to be epithetical cancer. The whole ulcer was dissected out, wide and deep, and skin immediately trans- planted. The area covered was 9J by 6 inches. The strips of skin have all taken, but granulation points crop out between the strips in places and show much les,s tendency to heal than in ordinary cases. In transplanting a surface so large and so uneven as this was after dissection, it was impossible to place the skin so accurately as not to leave some little spaces uncov- ered. These are the spaces which still show granulation between the strips of skin. On the whole nineteen-twentieths of the surface was covered with healthy skin at the end of three weeks, and this case only differs from the others in that there is apparently not the same tendency to rapid extension of normal epithelial growth from the edges of the transplanted strips. Case 34, a boy aged 13, met with an elevator accident on the 3rd of October last, whereby the skin, fascia, part of the tibialis anticus muscle, and a large portion of the periosteum, from the middle third of the antero-lateral surfaces of the tibia were torn off and stripped down to the ankle. These parts were replaced as well as possible, but their vitality had been des- troyed and sloughing followed. When the sloughs had been removed the leg was dressed carefully from time to time until the bared surface of the tibia was covered with granulations. Skin was then transplanted in the ordinary way on the 22nd of '• I November last. The dressing was removed on the eighteenth day after operation, when the wound, which measured 10} inches in its greatest length by 0} in its greatest breadth, and completely encircled the leg at its inferior extremity, was founJ to be completely healed. Case 36 may be briefly mentioned as a type. A young man aged 18 had both his legs burnt by falling into boiling soap in August, 1889. Healing progressed rapidly for a time and then became gradually slower and slower, until, for more than a year before admission, no progress whatever had been made, and an ulcer remained on the posterior surface of each leg about the junction of the middle and lower thirds. Thirteen days after operation the skin was found to have taken perfectly. I am enabled to present this patient for your inspection on this the sixteenth day after operation. With regard to the operation itself, it id sufficient to say that perfect asepsis, a broad-bladed and sharp razor, and ordinary manual dexterity, are the essen- tials to success. No preparation of the patient nor the part to be operated upon is necessary beyond the cleansing processes which are necessary in every operation. Several of the patients here reported were taken from the out-patient department with filthy clothing and skin, and foul- smelling ulcers, direct to the operating room (having of course had a bath and thorough cleansing of the parts to be operated upon). A single dressing of dry sublimated gauze, which is usually removed at the end of the third week, is the only after- treatment necessary. When this is removed the newly devel- oped skin is protected for a couple of weeks with a pad of gauze and a bandage. In those cases in which skin was transplanted to the face and a single dry dressing was impossible, the wound was kept moist with normal salt solution as recommended by ; Thiersch. This form of dressing is far more troublesome and less satisfactory than the dry dressing. All the cases here reported have been operated upon at a single operation, — that is the ulcer was scraped or dissected out and the skin applied immediately. In cases where it is necessary to dissect out a large area of skin (such as case 32) it would undoubtedly be 8 better to apply a gauze dressing for twenty-four or forty-eight hours to stop the oozing of blood, which is considerable, and transplant the skin at a second operation. Note. — Cases 82 and 85, which were not completely healed when the foregoing was written, have recovered perfectly, — the former in six weeks and the latter in five.
