AbstractAbstract PDF
Delayed closure of an open abdomen (OA) is a clinically challenging task despite its various modalities. It is substantially more difficult when the duration of OA treatment is prolonged due to a patient’s condition. We introduced the management of a patient who had a delayed OA treatment spanning approximately 3 months due to severe abdominal contamination. The 64-year-old male patient had an injured pelvis pressed by a road roller. After visiting a trauma center, the patient initially underwent damage control surgery and OA management; however, early primary abdominal closure failed due to severe peritonitis. After negative pressure wound therapy for several months, an acellular dermal matrix graft followed by a skin graft were successfully used as treatments. A combination of acellular dermal matrix graft, negative pressure wound therapy, and skin graft techniques is a considerable management sequence for patients subjected to delayed OA treatment.

AbstractAbstract PDF
Purpose

Negative laparotomy in patients with abdominal penetrating injuries (APIs) is associated with deleterious outcomes and unnecessary expense; however, the indications for laparotomy in hemodynamically stable patients with ambiguous computed tomography (CT) findings remain unclear. This study aimed to identify the factors associated with negative laparotomy. findings

Methods

Data of patients who underwent laparotomy for APIs between 2011 and 2019 were retrospectively reviewed. Patients who presented with definite indications for laparotomy were excluded. The patients were dichotomized into negative and positive laparotomy groups, and the baseline characteristics, laboratory test results, and CT findings were compared between the groups.

Results

Of 55 patients with ambiguous CT findings, 38 and 17 patients were assigned to the negative and positive laparotomy groups, respectively. There was no significant difference between the groups with respect to the baseline characteristics or the nature of the ambiguous CT findings. However, the laboratory test results showed that there was a difference in the percentage of neutrophils between the groups (negative: 55.6% [range 47.4–66.1%] vs. positive: 79.8% [range 77.6–88.2%], p<0.001), although the total white blood cell count was not significantly different. The mean duration of hospital stay for the negative laparotomy group was 13.1 days, and seven patients (18.4%) experienced complications.

Conclusions

Diagnostic factors definitively indicative of laparotomy were not identified, although the percentage of neutrophils might be helpful. However, routine laparotomy in patients with peritoneal injuries could result in instances of negative laparotomy.

AbstractAbstract PDF

Non-operative management has been preferred in blunt spleen injury. Moreover children are more susceptible to post-splenectomy infection, spleen should be preserved if possible. However, splenectomy is inevitable to patients with severe splenic injury. Therefore splenic autotransplantation could be the last chance for preserving splenic function in these patients although efficacy has not proven. Here we reported four cases of children who were underwent splenic autotransplantation successfully after blunt trauma.

AbstractAbstract PDF
Purpose
Open pelvic bone fractures are relatively rare and are considered more severe than closed fractures. This study aimed to compare the clinical outcomes of open and closed severe pelvic bone fractures.
Methods
Patients with severe pelvic bone fractures (pelvic Abbreviated Injury Scale score, ≥4) admitted at a single level I trauma center between 2016 and 2020 were retrospectively analyzed. Patients aged <16 years and those with incomplete medical records were excluded from the study. The patients were divided into open and closed fracture groups, and their demographics, treatment, and clinical outcomes were compared before and after 1:2 propensity score matching.
Results
Of the 321 patients, 24 were in the open fracture group and 297 were in the closed fracture group. The open fracture group had more infections (37.5% vs. 5.7%, P<0.001) and longer stays in the intensive care unit (median 11 days, interquartile range [IQR] 6–30 days vs. median 5 days, IQR 2–13 days; P=0.005), but mortality did not show a statistically significant difference (20.8% vs. 15.5%, P=0.559) before matching. After 1:2 propensity score matching, the infection rate was significantly higher in the open fracture group (37.5% vs. 6.3%, P=0.002), whereas the length of intensive care unit stay (median 11 days, IQR 6–30 days vs. median 8 days, IQR 4–19 days; P=0.312) and mortality (20.8% vs. 27.1%, P=0.564) were not significantly different.
Conclusions
The open pelvic fracture group had more infections than the closed pelvic fracture group, but mortality was not significantly different. Aggressive treatment of pelvic bone fractures is important regardless of the fracture type, and efforts to reduce infection are important in open pelvic bone fractures.
