Management of gastric injuries

Gastric Injury at Laparoscopy for Gynecologic Indications: A Systematic Review

OBJECTIVE

This systematic review aims to identify causes of increased risk for and location and mechanism of gastric injury at laparoscopy for gynecologic indications and determine optimal management.

DATA SOURCES

A prospectively registered systematic review (PROSPERO: CRD42021237999) was undertaken and performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Databases searched included Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Medline, Embase, Web of Science, SCOPUS, and Google Scholar from 1960 to 2021.

METHODS OF STUDY SELECTION

All study types were included involving female patients of any age with gastric injury at laparoscopy for gynecologic indication.

TABULATION, INTEGRATION, AND RESULTS

A total of 6294 articles were screened, from which 67 studies were selected for a full-text review. Twenty-eight articles were included, which contained 42 cases drawn from 7 observational studies, 4 case series, and 17 case reports. Of these, 93% (39/42) were at the time of laparoscopic entry, with Veress entry technique used in 79% of these cases (31/39). Eighteen cases reported an entry point, with 77% (14/18) occurring at the periumbilical entry point and 11% (2/18) occurring at Palmer's point. Of the cases with reported etiology for gastric distention or displacement, 64% (9/14) were owing to anesthetic cause. The most common sites of gastric injury were on the anterior stomach wall (n = 8) and the greater curvature (n = 5). Among patients with reported management (32/42), a similar proportion were managed conservatively (11) when compared with repair through laparotomy (13) or laparoscopy (8). All injuries were detected intraoperatively with no reported short-term sequelae.

CONCLUSION

This systematic review of the literature reveals that gastric injury at laparoscopy for gynecologic indications is a rare complication predominantly occurring during laparoscopic entry, most commonly at the periumbilical entry point. When detected intraoperatively, conservative management, laparoscopic, or open repair in the appropriate patient has been performed with no short-term sequelae. The limitations of this review include paucity of cases, detail, and timeline of publications.

Contrast study after gastric repair: a review of incidence, outcomes and risk factors at an adult level 1 trauma center

PURPOSE

The role of contrast study after traumatic gastric repair, continues to be controversial. To that end, we aim to review the incidence, outcomes, and risk factors of patients undergoing contrast study after traumatic gastric repair.

METHODS

This was a retrospective review of all trauma patients admitted to a level 1 trauma center that sustained gastric injuries with subsequent repair between 2011 and 2018. Demographics, surgical interventions, complications, and clinical outcomes were evaluated. Statistical analysis included Chi-square/Fisher exact univariate analysis and multivariate logistic regression analysis with a 5% significance level.

RESULTS

A total of 233 patients received a gastric repair, of whom 49 (21%) had a contrast study performed. Out of 49 patients with a contrast study, one was found to have a gastric leak. Mean time to contrast study was 6.3 ± 2.7 days. There was no statistically significant difference in post-operative complications between non-contrast and contrast study groups. Multivariate logistic regression analysis demonstrated a lack of statistical significance in clinical risk factors that would lead to obtaining a contrast study.

CONCLUSION

Gastric leak after repair is rare and there is no statistically significant difference in clinical outcomes when comparing patients who underwent contrast study to those who did not. Routine contrast study after traumatic gastric repair may not be necessary and further evidence is warranted to determine the risk factors for a selective contrast study.

Gastric Injury Increases Infections in Trauma Patients

Some physicians feel gastric injury is not a significant contributing factor to the adverse outcome of trauma patients, but rather a marker of epigastric injury. We hypothesized the addition of a gastric injury to multiple injured trauma patients would increase infection rate. We conducted a retrospective study comparing 450 consecutive patients with full-thickness gastric injury with 983 patients without gastric injury during the same time period. Infection rate in patients with gastric injury was 44 per cent (200 of 455) and significantly higher than 36 per cent (357 of 983) seen without gastric injury (P = 0.006). Logistic regression revealed gastric injury was an independent risk factor for infection controlling for age, Injury Severity Scale, gender, mechanism of injury, shock, and associated injuries (P = 0.047). Requiring a transfusion, Injury Severity Scale, colon injury, age, pancreas injury, and emergency department shock were also independent risk factors for developing an infection. The addition of a gastric injury to a trauma patient appears to increase the risk for infection.

Factors affecting prognosis in patients with gastric trauma

Morbidity and mortality after gastric injury is usually the result of associated injuries. The authors conducted a retrospective study of 544 consecutive patients with gastric trauma requiring emergency surgery. Blunt injuries had the highest mortality and length of stay. The mortality of a proximal stomach injury was 43 per cent (9 of 21) and was significantly higher than the 19 per cent mortality seen in patients with more distal injuries (P < 0.01). The majority of gastric injuries were closed primarily (492 of 544 or 90%). The patients requiring more than a primary repair had a higher mortality (22 of 52 or 42% vs. 87 of 492 or 18%; P < 0.001), required more blood (16+/-16 U vs. 6+/-11 U; P < 0.001), had an increased rate of surgical site infections (17 of 52 or 33% vs. 75 of 492 or 15%; P = 0.001), and had an increased length of stay (20+/-30 days vs. 13+/-18 days; P = 0.024). There were 22 patients with an isolated gastric injury, and all of these patients survived. Patients with an associated arterial injury had the highest mortality (49%) and highest incidence of shock (64%). Patients with colon and gastric injuries had the highest (48 of 176 or 52%) surgical site infection rate. Isolated gastric injury is rare, but is associated with low morbidity and mortality. The mechanism of injury, location of injury, and type of repair used all affect patient outcomes with gastric injury.

Analysis of 162 Colon Injuries in Patients with Penetrating Abdominal Trauma: Concomitant Stomach Injury Results in a Higher Rate of Infection

BACKGROUND

Fecal contamination from colon injury has been thought to be the most significant factor for the development of surgical site infection (SSI) after trauma. However, there are increasing data to suggest that other factors may play a role in the development of postinjury infection in patients after colon injury. The purpose of this study was to determine the impact of gastric wounding on the development of SSI and nonsurgical site infection (NSSI) in patients with colon injury.

METHODS

Post hoc analysis was performed on data prospectively collected for 317 patients presenting with penetrating hollow viscus injury. One hundred sixty-two patients with colon injury were subdivided into one of three groups: patients with isolated colon wounds (C), patients with colon and stomach wounds with or without other organ injury (C+S), and patients with colon and other organ injury but no stomach injury (C-S) and assessed for the development of SSI and NSSI. Infection rates were also determined for patients who sustained isolated gastric injury (S) and gastric injury in combination with other injuries other than colon (S-C). Penetrating Abdominal Trauma Index, operative times, and transfusion were assessed. Discrete variables were analyzed by Cochran-Mantel-Haenszel chi2 test and Fisher's exact test. Risk factor analysis was performed by multivariate logistic regression.

RESULTS

C+S patients had a higher rate of SSI infection (31%) than C patients (3.6%) (p=0.008) and C-S patients (13%) (p=0.021). Similarly, the incidence of NSSI was also significantly greater in the C+S group (37%) compared with the C patients (7.5%) (p=0.07) and the C-S patients (17%) (p=0.019). There was no difference in the rate of SSI or NSSI between the C and C-S groups (p=0.3 and p=0.24, respectively). The rate of SSI was significantly greater in the C+S patients when compared with the S-C patients (31% vs. 10%, p=0.008), but there was no statistical difference in the rate of NSSI in the C+S group and the S-C group (37% vs. 24%, p=0.15).

CONCLUSION

The addition of a gastric injury to a colon injury has a synergistic effect on the rate of postoperative infection.

Impact of stomach and colon injuries on intra-abdominal abscess and the synergistic effect of hemorrhage and associated injury

BACKGROUND

Colon wounds are recognized to be highly associated with intra-abdominal abscess (IAA) after penetrating trauma, whereas gastric wounds are thought to contribute minimally to abscess because of the bactericidal effect of low pH. This study evaluated the impact of stomach or colon wounds, the contribution of other risk factors, and associated abdominal injuries on IAA.

METHODS

Patients with penetrating colon or stomach wounds during a 10-year period were reviewed and stratified by age, Injury Severity Score, transfusions, and associated abdominal injuries. Early deaths (<48 hours) from hemorrhage were excluded. Outcomes analyzed were IAA and death.

RESULTS

A total of 812 patients were identified. There were 32 late deaths (4%), of which 28% were attributable to IAA and multiple organ failure. IAA rates for isolated stomach or colon wounds were 0 and 4.2%, respectively. The presence of associated injuries increased IAA rates to 7.5 and 8.8%, respectively. Independent predictors of IAA determined by multivariate analysis included age, transfusions, gunshot wounds, and associated injuries to the liver, pancreas, and kidney.

CONCLUSION

Gastric injuries are equivalent to colon wounds in their contribution to IAA. Contamination from either organ without associated injury is minimally associated with IAA, but injury to both appears synergistic. The immunosuppressive effects of age and hemorrhage, in addition to significant associated injury, enhance the development of IAA.
