ROGRESS in the management of wounds of coIon and rectum has IargeIy resuIted from experiences in miIitary surgery [r-4] and more recentIy from observations made in Iarge civiIian hospitaIs [f-9]. During WorId War II and the Korean conflict, the routine use of exteriorization or proxima1 coIostomy resuIted in a striking reduction in mortaIity, and this method has subsequentIy become popuIar in civilian practice. However, it has become evident that exteriorization or prox$maI coIostomy may not be necessary in the majority of civiIian injuries and may be associated with proIonged convaIescence and additiona complications
P the
MANAGEMENT
In an attempt to further evaIuate this probIem, an analysis was made of 138 patients with coIon and recta1 injuries treated on the TABLE
The preoperative compIete physica
management consisted of evaIuation of the patient, TABLE

AND
Loma Linda University surgica1 services from 1956 to 1962. There were twenty deaths in this totaI group, a mortaIity rate of 14.5 per cent. One hundred thirty-two patients of the 138 received operative treatment. The average age was 34.6 years, with extremes being a gir1, age three, and a man of ninety-four years. The mechanisms of trauma are outIined in TabIe I. The number of injuries with accompanying mortaIity for each anatomica segment of the coIon and rectum are Iisted in TabIe II. As has been frequently emphasized, recta1 injuries, particuIarIy those that are extraperitonea1, tend to be more serious than injuries elsewhere in the coIon. The transverse colon was the site most frequentIy injured. (Fig. I.) TweIve patients had three or more perforations, of whom three died.

Urography, sigmoidoscopy and abdominal paracentesis were utiIized when indicated. Preoperative antibiotics were frequently given. Operative management consisted in contro1 of hemorrhage, closure of perforation sites, repair of other injuries when present, and adequate drainage when indicated. Three genera1 methods were utiIized whichare summarized in TabIe III. (Fig. 2.) The first was primary closure in which the injured site was either debrided and closed or resected with primary anastomosis [g]. Seventy-six patients were in this primary cIosure group with a mortaIity rate of 6.6 per cent. Of these, sixtynine had the injury site debrided and closed, and seven had the site resected with primary anastomosis. Four of the seven primary resections were right coIectomies, one patient died. There were four deaths among the sixty-nine patients treated by debridement with cIosure. Forty-five of the injuries in this group were in the ascending or transverse coIon with three deaths; thirty-one injuries were in the Ieft coIon incIuding the rectum, with two deaths. The second surgical method was primary cIosure with exteriorization which was used in ten patients with one death [a. Six of the injuries occurred in the hepatic ffexure or transverse coIon with one death; four injuries were in the Ieft coIon. The third method was primary venting (coIostomy or cecostomy) utiIizing a staged 366

approach. Forty-six patients were treated in this way, eIeven deaths occurred, an operative mortaIity rate of 23.9 per cent. Of the forty-six patients, twenty-nine had a proximal vent, and five died; seventeen had exteriorization of the site of injury with six deaths. Thirteen injuries occurred in the ascending or transverse colon with three deaths, and thirty-three injuries were in the left colon including rectum with eight deaths. There were three deaths in the remaining six patients in whom no surgica1 procedure was performed. It wouId appear in review that the three deaths wouId have been prevented by prompt surgical intervention. Of the three survivors two had posterior extraperitonea recta1 perforations and the other had an intraperitoneal recta1 injury. This intraperitonea1 perforation which was of specia1 interest was caused by an enema tip one month prior to admission. A c&de-sac abscess had deveIoped, which spontaneousIy drained at sigmoidoscopy. The time interva1 from injury to treatment is significant. It has been noted by many authors that resuIts improve when surgica1 treatment is prompt, especiaIIy under six hours. Data reIated to a time interval is summarized in Table IV. TabIe v lists the associated trauma in the 132 operated cases. Forty-four patients had a

one death (IO per cent). The probIem of handling the exteriorized coIon is dificult [IO]. Of the ten cases exteriorized six had dehiscence of the closure with the formation of a coIostomy, thus converting them to a vent at the site of the injury. OnIy four were repIaced without having to open the coIon, one of which cIosure sites reperforated after it was repIaced and required another exteriorization with the patient eventuaIIy dying. Seventeen compIications occurred in the nine remaining patients. There were four intraperitonea1 Ieaks either at the site of cIosure of the injury or after a subsequent coIostomy cIosure (an incidence of 40 per cent Ieaks). One patient had a subphrenic and cuI-de-sac abscess which required drainage. EarIy smaI1 bowe1 obstruction occurred in two patients, which required operative decompression. Another patient had coIon obstruction due to tension of exteriorized coIon over the supporting rod. Nine miscelIaneous complications occurred. In the forty-six cases in which a primary vent was utiIized (TabIe x), eight patients (17.4 per cent) had an uneventfu1 recovery. EIeven deaths occurred (23.9 per cent mortaIity rate). Wound infection occurred in twenty-one cases. CoIostomy probIems deveIoped in ten patients (21.7 per cent) incIuding skin autodigestion, pericolostomy abscess and proIapse; three coIostomy cIosure Ieaks, smaI1 bowe1 obstruction, gangrene of coIostomy, and three coIostomy closure strictures. Other compIications incIuded four smaI1 bowe1 obstructions which required Iaparotomy, three patients with intraperitonea1 sepsis (subphrenic abscesses), and twenty-four misceIIaneous complications.

PROCEDURES
The one death in the primary cIosure with exteriorization group was due to dehiscence of the suture Iine when the coIon was repIaced. Of the eIeven deaths with primary venting procedures, nine were caused by massive injury or generaIized peritonitis and were not reIated to operative error. A fifty-three year oId man with a rectosigmoid foreign body perforation had a wound evisceration and died from cardiac arrest at surgery. A fifty-seven year old man had blunt trauma injury with Iaceration of the extraperitonea1 rectum treated by coIostomy and died of an unreIated aspiration probIem.
of CoIon Trauma jority of battIefieId coIon wounds requires an exteriorization approach, whereas a Iarge percentage of civilian coIon injuries may be accompanied by less IocaI tissue destruction and are adaptabIe to primary cIosure. It is of interest to note that there were four patients (5.3 per cent) who had a dehiscence of the primary suture Iine. Two of these died, but the other two were successfuIIy managed, one by a coIostomy and the other by right coIectomy. Wound infection proved to be a common compIication in primary cIosure. Of ten patients who had primary cIosures of their coIon perforation associated with exthere were four instances of teriorization, suture-Iine dehiscence. There were frequent complications associated with the coJostomy in the primary vent and exteriorization groups. SUMMARY
AND
CONCLUSIONS
This study is an anaIysis of the management of 138 cases of coIon and recta1 trauma. Primary cIosure was used in seventy-six instances with a mortaIity of 6.6 per cent; it is considered to be the treatment of choice when circumstances permit [7-91. When coIon wounds are accompanied by extensive IocaI tissue injury or massive feca1 peritonitis, primary venting procedures are recommended. AIthough selected wounds of the extraperitonea1 rectum may be treated by primary repair, the majority require proxima1 coIostomy and perinea1 drainage [IO-141. Extensive muItipIe organ trauma and associated diseases are serious factors in prognosis. REFERENCES

The effective routine use of exteriorization procedures during WorId War II and the Korean conff ict had a widespread inff uence in civilian practice. However, as the differences between military and civilian injuries have been evaIuated, it has become evident that a different approach shouId be considered in nonmiIitary hospitak.

DISCUSSION JACK FARRIS (Los AngeIes, CaIif.): I am certain that we are al1 grateful to Dr. Vannix and his associates for this presentation which caIIs our attention to the feasibiIity of definitiveIy treating coIon injuries by primary suture. Those who have done this type of cIinica1 investigation are aware, I am certain, of the enormous amount of effort that goes into the analysis of these data. As you wiI1 recaI1, there were 132 operations performed in 138 patients with twenty deaths, a mortaIity rate in the over-a11 group of about fourteen or 14.5 per cent. Of interest to us today is the group of seventysix patients who were treated by primary cIosure with a mortaIity rate of 6.6 per cent. I am certain that Dr. Vannix did not impIy the Iower mortaIity rate in the primary cIosure group was a direct resuIt of the method of treatment, but rather that this group of patients, nameIy, those without massive tissue injury, without sepsis, and those who have had a short time interva1 between injury and operation, are usuaIIy chosen for this particular modaIity. I have been interested recentIy in reviewing some of the pertinent literature on colon injuries since being given this assignment by Dr. Vannix and his coIIeagues; I was surprised to find numerous references in the Iiterature to the use of primary cIosure in the treatment of coIon injuries. As a matter of fact, OgiIvie in 1944 suggested primary suture particuIarIy for ceca1 wounds and wounds of the ascending colon. Those of us in the European theater during the war treated a11 coIon injuries by coIostomy di370
and Joergenson
version, aIthough we had a tacit agreement that most Iesions of the cecum and the ascending coIon, if at a11 suitabIe, shouId be treated by primary suture or by right coIectomy and iIeotransverse coIostomy rather than by iIeostomy. AIso, I was interested to see that Doctors Christianson, Ignatius and Mathewson had reported a number of patients who had been treated in civilian Iife by primary cIosure with no Ieaks and no deaths. Innes, in 1947, reported twenty-five injuries of the coIon in civiIian practice which were cIosed primarily with no Ieakage and IOO per cent recovery. About forty-seven years ago, a Captain Fraser, who was in the RoyaI Canadian MedicaI Corps, pubIished in Tbe British Medical Journal an extensive experience with 300 abdominaI injuries during WorId War I; he says, in summarizing his experience, that at first he folIowed a practice of a proximal coIostomy in combination with the operation of suture. “There are the obvious advantages that it increases the safety of the suture whiIe it obviates the passage of feca1 matter through the damaged gut. At this time we were suspicious regarding the viabiIity of the Iine of coIon suture, and we felt that coIotomy had a greater security. Later we recognized that the performance of proxima1 coIostomy was rareIy necessary, and we have, therefore, aImost abandoned its use. We now reinforce the suture line by an omenta1 graft. We beIieve that our results have improved since we have aItered our procedure.” This was about fifty years ago. So, I would compIiment the authors on a most carefu1 study of a reaIIy significant number of cases, and I am certain that I can summarize their beIiefs and emphasize that this particuIar maneuver shouId be used onIy in the ideal case, in a case in which there is minima1 tissue injury, when a short time has eIapsed, and where, perhaps, there is a skiIIfu1 surgeon. I wiI1 summarize by saying that, in short, there is a pIace for both methods of treatment, and that the two stage procedures in my opinion aIways wiI1 occupy an important pIace in the armamentarium of the general surgeon. I wouId Iike to close by CompIimenting Dr. Vannix on his beautiful presentation, his exceIIent sIides, and I think he Iends credence to the axiom that a good presentation for its background has lots of preparation. CARLETON MATHEWSON, JR. (San Francisco, Calif.): I hope you wiII forgive me for speaking again, but I, too, wouId like to extend my compliments to the authors and wouId Iike to emphasize the important difference between treating patients with injuries of this type in civiIian Iife and those in wartime. CertainIy, we who see these patients early and are abIe to keep them under constant observation are justified in doing primary cIosures
SurgicaI Management of the coIon. In wartime, however, the transportation probIems and rapid evacuation make it dangerous and, therefore, unjustified. My main reason, however, for speaking is to object to the faith that a great many people have in proxima1 colostomy. A proximal coIostomy does act as a vent and gets rid of gas and pressure, but rareIy gets rid of contamination. One, in treating a sigmoid perforation from a diverticuIitis, frequentIy wiI1 do a transverse coIostomy; often doing the transverse coIostomy on the right side of the colon in order to faciIitate subsequent Ieft coIectomy and re-establishment of continuity. In so doing, one Ieaves a tremendous reservoir of retained feca1 materia1 which continues to con-
of CoIon Trauma taminate the area of perforation. If one does choose to do a proxima1 coIostomy, it should be done in as cIose approximation to the injury as possibIe. DAVID B. HINSHAW (closing): We wouId Iike to thank Dr. Farris and Dr. Mathewson for their kind and thoughtfu1 comments. We wouId agree, strongIy so, that a surgeon shouId be famiIiar with a11 methods of dealing with this type of injury. It is cIear that each case must be individuaIized, and that no “ruIe of thumb” can be Iaid down for the treatment of coIon and recta1 injuries. We appreciate the opportunity to present this paper to the Association.
