Trauma 20 Years Ago: Colon Injury

Through the 1970’s and 80’s, a colon injury was automatically managed by repair/resection coupled with a diverting colostomy. This technique became commonplace due to bad experiences with repair attempts during earlier decades.

During the late 70’s, a few trauma centers began dabbling in primary repair. At Wayne State University in Detroit, John Kirkpatrick had popularized an exteriorization technique. This involved repairing the colon and bringing the area of repair to the outside of the body. The area was watched for several days and if no breakdown was noted, it could be dropped back into the abdomen with a relatively minor procedure. 

After the success of exteriorization, some of the surgeons at Receiving began repairing colon injuries and leaving them in the abdomen. They retrospectively looked at their experience with this radical idea from 1980 to 1987. Injuries were predominantly penetrating. From 1980 to 1983, 29% of patients were managed in this way. During the final years, the use of this technique increased to 56%. 

Interestingly, Injury Severity Score in patients who did not get colostomy was higher, but the number of complications (leaks, intra-abdominal abscesses) was lower! Colostomy patients had 15 abscesses, while those without colostomy had 1 leak and only 5 abscesses.

This paper represents one of the first reports on colon injury management without colostomy, and set the stage for additional trials. It has led to the nearly routine use of this technique in current times.

Trauma 20 Years Ago: Seatbelt Injury

We take for granted that the so-called seatbelt sign is a harbinger of bad things in the abdomen. One of the first papers on this topic appeared in the February 1990 issue of the Journal of Trauma, entitled “Intra-abdominal Seatbelt Injury.”

The paper presents 8 cases who presented to the ED with a seatbelt sign after a motor vehicle crash. They found that serious injuries to the bowel and mesentery might be present without early symptoms or physical signs, and that CT scan and peritoneal lavage were not fully reliable in finding the injuries. Their conclusion was that the always wise “high index of suspicion” should be used in these patients.

Current day thinking has not changed much. During the last two decades, sentiment has swung from always operating based on these finding to being more selective. We recommend using good judgment. Seatbelt sign should always arouse a healthy suspicion for injury. A CT scan is now mandatory. If anything unusual is found (free fluid, bowel wall or mesenteric thickening or stranding) then a trip to the OR is indicated. Small bowel injuries may not become symptomatic for 12-72 hours, increasing the eventual complication rate if treatment is delayed.

Trauma Twenty Years Ago: January 1990

It’s always interesting to review the trauma literature of days gone by to see where we’ve been and how it impacts where we are today in trauma care. Here are a few articles from the Jan 1990 Journal of Trauma (Volume 30 Number 1) worth commenting on:

Efficacy of Liver Wound Healing by Secondary Intent. Dulchavsky et al, page 44-48. This paper compared wound healing using tensile strength in pigs and dogs. The authors compared primary operative closure, closure with an omental buttress, and healing by secondary intention. They found that the strength of secondary healing equaled or exceeded that in both types of operative repair by 6 weeks post-injury. This paper and several similar ones laid the groundwork for our understanding of solid organ healing and lend weight to the somewhat arbitrary guidelines of resuming full physical activity after 6 weeks.

Intestinal Injuries Missed by Computed Tomography. Sherck et al, page 1-7. The authors retrospectively looked at 10 CT scans done over a 9 year period that were done in patients who eventually were found to have an intestinal injury. The injury became apparent in 2 hours to 3 days after the traumatic event. Even when the authors knew that a bowel injury was present, they could definitively diagnose the problem on the initial CT in only 2. The authors concluded that CT could not reliably detect these injuries. Little has changed since this paper was published, even though the scan technology has improved greatly (1 or 2 slice scanners in 1990, 16-64 slices now). We have gotten better at detecting bowel injury with better resolutions, but the diagnosis still remains a clinical one.

Techniques of Splenic Preservation Using Fibrin Glue. Shoemaker et al, page 97-101. The senior author first described the use of fibrin glue in splenic injury in 1983, and continued to investigate it over the next 7 years. This paper was the largest human series at the time. The authors found that it limited blood loss and transfusions, although there was no actual control group. They found that it increased splenic salvage rates to 86% in operative cases, and repeat CT did not show rebleeding or abscess formation. This study added a new technique to the trauma surgeon’s armamentarium in dealing with solid organ injury. Although later studies did find a modest increase in abscess formation, the technique remains a viable alternative when operatively managing solid organ injury. Overall, it is not used as much now because nonoperative management has become quite refined, with a success rate of about 93%.
