152 DeLaware Srave Mepican JourxXar, CERTAIN ASPECTS OF SURGERY OF THE NEWBORN *« C. Kvererr Koop, M, D.,** Philadelphia, Pa, To those who interest. themselves primar- iy in the surgical problems of infaney and childhood, there seems to be no end to new ideas which ean be developed in the opera- tive and post-operative care of children, which lead to smoother con ralescenee, decreased morbidity, and lower mortality rates. In the field of pediatric surgery, however, the chal- lenge still lies in the surgical management ot those congenital anomalies which are in- compatible with life, but which are amenable to surgical correction. There are four such problems which might be included in this group without question. They are omphalocele, atresia of the esophagus with or without tracheoesophageal fistula, atresia of the bowel and imperforate anus. To this group I would also add meconium ileus and diaphragmatic hernia. Meconium ileus should be added because of the distres- sing mortality this problem carries with it about the country, and diaphragmatie hernia because its mortality, although not one hun- dred per cent, is so close to it as to be inelud- ed in this series. The management of omphalocele was mod- erately efficient as outlined by Ladd and Gross' some years ago, but an even superior method is that described more recently by Gross*, wherein the membranes of the ompha- locele are not dissected free, but rather are covered by skin which ean be loosened from surrounding structures and stretched over the surface of the membrancous covering of the abdominal viscera. We have made but one slight improvement on this technique. In large omphaloceles where disproportion be- tween the protruding viscera and available skin is great, it is possible to compress the abdominal viscera by rolling the membran- eous covering in much the same way that one would roll down the top of a paper bag after bringing the two sides together, and then to approximate the skin edges while holding the viscera, thus tightly compressed. Omphalo- celes extending from the xiphoid to the pubis, which otherwise might not. be correctible by * Read before the Medical Society of Delaware, Wil- mington, October 9, 1951. . ; ** Surgeon-in-Chief, Children's Hospital. JUNE, 1952 surgical means, can be closed in this fashion. In reference to problems of atresia of the bowel, recovery still seems to be proportional to the age of the patient, the surgical care exercised at the time of operation, and the exeelUcney of post-operative care. Meconium ileus, diagnosed early by the signs of vomiting, distention, viseid seeretion, and shadows resembling feces on X-Tay ¢xam- ination of the abdomen is beg successfully treated insofar as the obstructive problem is concerned by a variety of surgical approaches with a decreasing mortality. Whether one performs a temporary ileostomy or resects the affected portion of the bowel, the use of pahereatie enzymes and preserved duodenal Juice are of great help in establishing the passage of stools. In the treatment of diaphragmatic hernias, we have abandoned the abdominal approach and routinely operate transthoracieally.* Tn the thoracic approach it is possible to open the chest of a distressed infant in a matter of a minute or two, and to eviscerate. the ab- dominal organs from the thoracic cavity, at which moment the baby becomes a satisfac- tory patient from the poiut of view of cardiac and respiratory reserve. The collapsed lung ean expand, the heart is no longer compres- sed, and the mediastinum may sluit back to its normal position. The surgeon need then be inno hurry, but can at his leisure replaee the abdominal viscera into the peritoneal eay- ity through the diaphragmatie defect; the chest is then closed in the usual fashion alter suturing the diaphragm, and the infant re- turned to his erib with a chest wound which he seems much better able to handle than a arge abdominal wound behind which are more abdominal contents than the peritoneal cavity can eonveniently aceommodate. We have done fourteen diaphragmatic repairs by this technique with one death, and that in a child with premature ossification of the skull and subdural and epidural hematomas. Having thus disposed of four problems with little more than a word, I would like to turn our attention to the two remaining problems: atresia of the esophagus, and imperforate anus, and outline a method of management for each which we have found satisfactory and which in each instance seems to be sume- JUNE, 1952 what at variance with the usual techniques employed. In the management of atresia of the esopha- gus our earlier method of management was that. used by most, a retro-pleural approach through the posterior mediastinum, at which time the tracheoesophageal fistula was ligated and an end-to-end anastomosis carried out between the blind pouch above and the open esophagus below. On the day after this pro- cedure a gastrostomy was done, feedings were delayed for a period of five to ten days, and frequently post-operative dilatations of the esophageal anastomosis were necessary in order to permit the passage of food through the sutured esophagus. This method of man- agement had many faults. The operative pro- cedure was long, it was difficult to stay out of the pleural eavity, the hospitalization was prolonged, and economic loss to the family was great. There was always the risk of re- vurgitated gastrostomy feedings, the need of two operations, and the delayed nutrition of the patient. Finally, the problem of esopha- geal dilatations and the occasional necessity for surgical closure of the gastrostomy was time-consuming. In addition, the patients irequently developed edema post-operatively, which in those children who died, at times approached a generalized anasarea. Under this technique we felt that we had done all that we could to improve our management, and the mortality was over fifty per cent. At the present time, we have altered our method of earing for these children in this manner: instead of using a retro-pleural ap- proach, we operate transpleurally and reduce the operative time from a period of twa to five hours, to an average operating time of an hour and fifteen minutes. No gastrostomy is carried out following operation if we have reasonable assurance that the suture line is tight. On the morning of the second post- operative day the patient is fed glucose water and his formula is increased rapidly to some- thing similar to that given to most newborn infants. By this method, not only is anes- thesia and operating time decreased, but only one operation is necessary, hospitalization is shorter, the eeonomic loss to the family is less, nutrition is maintained, and surprisine- ly enough, esophageal dilatations do not ap- pear to be necessary as frequently as hereto- DELAWARE Strate Mipican Journal 153 fore, Edema is now seldom seen because we maintain these children on no salt) (except that contained in blood transfusions) for the first three post-operative days, and then limit Muids to approximately 60 ce lh/day. Iv one excludes patients with a seeond anomaly incompatible with life and patients with multiple congenital defects, whieh in themselves carry a high mortality, the mor- tality is surprisingly low. Out of 20 such patients we have had 15 survivals. our was- trostomies were done in this group and two patients needed dilatations of the esophagus. This method seems to us to be a rational ap- proach to the problem of atresia of the esopha- gus, not only in the hands of the pediatric surgeon, but also in the hands of the tharacie surgeon who only occasionally deals with such problems. The risks are less, the procedure easier, and the results better, The problems resulting from the improper management of imperforate anus have long been a burden to us. Beeause this is the most common of the congenital anomalies ineom- patible with life, a laree number of sureeons encounter the lesion and operation is earried out by many unfamiliav with the end results of this variety of surgery. Most patients with imperforate anus are divided into two types: Those in whom the blind rectal pouch ean he reached from below, and those in whom the distance between the anus and the eolon. ig too great to be bridged by a perineal opera- tion, in whom a colostomy seems the proced- ure of choice. This is a satisfactory: classifi- cation of patients, but the seleetion of oper- ative procedures for each is frequently un- Wise, First, and most dangerous, is the common attempt to bridge too wide a wap between anus and colon by the perineal approach, When such is done it is possible to bring colon mucosa to perineal skin for a suture line, hut this is done at the expense of nerve and blood supply to adjacent areas, Such suture lines, under great tension, do not hold, and there develops in a matter of days after operation a rectal canal surrounded by fat and muscle and Hned with eranulation tissue. This in turn hecomes a tight, relatively long stricture which ean make the patient a rectal eripple for the rest af his days. Not only are these strietures very difficult to correct but 154 DELAWARE Strate MepicaL JOURNAL frequently their correction leads to incontin- ence. If they are not corrected, obstructive megacolon may ensue. The second variety of mistake is made in those patients in whom a colostomy seems necessary. The colostomy is carried out in the sigmoid colon, thereby utilizing the re- dundant loop of colon which should be left free to provide bowel to construct pelvic colon, rectum, and anal canal at the time of definitive operation. These two errors can be eliminated by never attempting to bridge a gap between colon and anus which is greater than 1.5 em., and when a colostomy seems indicated, by placing it in the right side of the transverse colon in order to leave as much distal colon as possible for use at the time of definitive operation. We attempt to divide all of our imperforate anus cases into three groups as to operative procedure. First, patients with a blind gap of 1.5 em. or less are approached through the perineum, and an anus constructed which usually has some sphincter. Secondly, pa- tients who weigh less than four and a half pounds, or who present some other medical problem which contraindicates major surgery, have a colostomy performed im the right trans- verse colon. These two methods could be car- ried out satisfactorily in almost any commun- ity where surgery is practiced. At the Children’s Hospital of Philadel- phia, we have added a third category of oper- ation, believing that we have sufficiently good anesthesia, nursing, and house officer care to warrant such type of work. Those with a gap between anus and colon of more than 1.5 em. have a definitive operation car- ried out at the time of admission to the hos- pital. A combined abdomino-perineal type of approach is carried out with the abdomen be- ing opened first and the blind end of colon secured and exteriorized. The patient is draped in such a way that one leg is outside the drapes and in the operative field. A small seetion of skin and skin only is excised from ihe region of the anus, the external sphincter cleanly divided, and a small hemostat is in- serted into the perineal body. This aperture is gradually enlarged until it is possible to reach up into the true pelvis, and bring down through the perineal canal thus made the blind loop of colon and exteriorize it through JUNE, 1952 the newly formed anus. These children are taken care of once and for all, and the only thing that remains to be done to them is to have the excess colon trimmed off by a very minor procedure just before discharge from the hospital.® Patients of three days of age or less tole- rate this extensive surgery without difficulty. It is of interest to note, however, that if such an operation is not carried out in this very early neonatal period, it becomes one of the most shocking procedures one can undertake in pediatric surgery, and therefore, by exper- ienece we have learned that if this cannot be accomplished early, one should do a colostomy and then at a later date, after the age of three or four months, perform the definitive operation by the combined abdomino-perineal approach just described. When patients are eared for by the three techniques outlined there should be no rectal strictures. Tight anuses can be dilated in infancy, resulting in a cosmetically acceptable anus, and a well- functioning lower bowel. Such patients take longer to train for stool habit than normal babies, but they usually can be made into satisfactory citizens from the point of view of bowel function. I will not go into the many problems of fistulae between the colon and the urinary tract, which so frequently complicate this con- genital defect. They can be managed satis- factorily during the procedures outlined. We have operated on almost forty of these young- sters in the last four years with one death and one failure. Several premature babies have died from other congenital anomalies before surgery was undertaken. The smallest baby we successfuly treated weighed two pounds, twelve ounces. None are now rectal cripples nor need look forward to that exist- ence in the future. In the same period of time we have treated a large number of pa- tients secondarily who had previous surgery at the time of birth, surgery which was not carried out according to the principles here stated. We think that the proper manage- ment of such patients could eliminate the very serious problems we see of fecal incon- tinenee, megacolon and rectal stricture fol- lowing surgery of imperforate anus. We believe that much can yet be done to improve the technique of operative proced- June, 1952 ure and post-operative management of pa- tients with atresia of the esophagus and im- perforate anus. We realize that a low mor- tality rate in a small series of patients may be misleading and that we have had a par- ticularly good succession of patients in both categories. Tlowever, we do believe also that some of the improved mortality is due to careful attention to detail based upon correct- ible errors of the past, and suggest that the method of management outlined for each of DELAWARE State MepicaL JOURNAL 155 these conditions warrants trial in other ped- iatric installations. 1740 Bainbridge Street REFERENCES 1.
