Gallstone Ileus as an Occult Cause of Small Bowel Obstruction and Subsequent Large Bowel Obstruction: A Report of a Rare Case [Case Report]
Luckman, Matthew; Ha, Rebecca; Vu, Alexander H; Han, Jane; Golden, Adam; Victory, Jesse
Gallstone ileus, a rare cause of mechanical bowel obstruction, occurs due to the formation of a cholecystenteric fistula allowing gallstones to migrate into the gastrointestinal tract. The condition occurs mostly in elderly patients, particularly women, and carries a significant mortality risk due to delayed diagnosis. This case report discusses a 77-year-old female patient with a history of chronic medical conditions, who self-presented with periumbilical pain, nausea, and reduced bowel movements. Initial imaging revealed pneumobilia and small bowel obstruction, leading to a diagnosis of partial obstruction attributed to adhesions. Despite surgical intervention and temporary symptom relief, the patient's condition deteriorated due to a subsequent colonic obstruction. The case was complicated by delayed recognition of gallstone ileus, as imaging initially misinterpreted the obstructive mass as a "stool ball" rather than a gallstone. Following diagnostic laparoscopy and subsequent exploratory surgeries, the patient was found to have a gallstone impacted in the rectum, leading to colonic ischemia and perforation. This resulted in progressive renal failure, respiratory failure, and ultimately, the patient's death in hospice care. This case underscores the diagnostic challenges of gallstone ileus and highlights two key delays: misattribution of obstructive symptoms to adhesions and failure to recognize colonic obstruction due to gallstone ileus. Early use of contrast-enhanced imaging and a high index of suspicion are crucial for timely diagnosis. This case emphasizes the importance of thorough inspection of the small bowel and ileocecal region during laparoscopy and the need for careful evaluation of imaging findings to improve patient outcomes in gallstone ileus cases.

Increased Use of Prehospital Tourniquet and Patient Survival: Los Angeles Countywide Study
Henry, Reynold; Matsushima, Kazuhide; Ghafil, Cameron; Henry, Rachel N; Theeuwen, Hailey; Golden, Adam C; Abramson, Tiffany M; Inaba, Kenji
BACKGROUND:Recent trends in prehospital tourniquet use remain underreported. In addition, the impact of prehospital tourniquet use on patient survival has not been evaluated in a population-level study. We hypothesized that prehospital tourniquets were used more frequently in Los Angeles County and their use was associated with improved patient survival. STUDY DESIGN:This is a retrospective cohort study using a database maintained by the Los Angeles County Emergency Medical Services Agency. We included patients who sustained extremity vascular injuries between October 2015 and July 2019. Patients were divided into the following study groups: prehospital tourniquet and no-tourniquet group. Our primary end point was in-hospital mortality. The secondary outcomes included 4- and 24-hour transfusion requirements and delayed amputation. RESULTS:A total of 944 patients met our inclusion criteria. Of those, 97 patients (10.3%) had prehospital tourniquets placed. The rate of tourniquet use increased linearly throughout our study period (goodness of fit, p = 0.014). In multivariable analysis, prehospital tourniquet use was significantly associated with improved mortality (adjusted odds ratio 0.32; 95% CI, 0.16 to 0.85; p = 0.032). Similarly, transfusion requirements were significantly lower within 4 hours (regression coefficient -547.76; 95% CI, -762.73 to -283.49; p < 0.001) and 24 hours (regression coefficient -1,389.82; 95% CI, -1,824.88 to -920.97; p < 0.001). There was no significant difference in delayed amputation rates (adjusted odds ratio 1.07; 95% CI, 0.21 to 10.88; p < 0.097). CONCLUSIONS:Prehospital tourniquet use has been on the rise in Los Angeles County. Our results suggest that the use of prehospital tourniquets for extremity vascular injuries is associated with improved patient survival and decreased blood transfusion requirements, without an increase in delayed amputations.
