Scanning the aged to minimize missed injury: An EAST multicenter study.

BACKGROUND: Despite the high incidence of blunt trauma in older adults, there is a lack of evidence-based guidance for computed tomography (CT) imaging in this population. We aimed to identify an algorithm to guide use of a Pan-Scan (Head/C-spine/Torso) or a Selective Scan (Head/C-spine ± Torso). We hypothesized that a patient's initial history and exam could be used to guide imaging. METHODS: We prospectively studied blunt trauma patients aged 65+ at 18 Level I/II trauma centers. Patients presenting >24 h after injury or who died upon arrival were excluded. We collected history and physical elements and final injury diagnoses. Injury diagnoses were categorized into CT body regions of Head/C-spine or Torso (chest, abdomen/pelvis, and T/L spine). Using machine learning and regression modeling as well as a priori clinical algorithms based, we tested various decision rules against our dataset. Our priority was to identify a simple rule which could be applied at the bedside, maximizing sensitivity (Sens) and negative predictive value (NPV) to minimize missed injuries. RESULTS: We enrolled 5,498 patients with 3,082 injuries. Nearly half (47.1%, n = 2,587) had an injury within the defined CT body regions. No rule to guide a Pan-Scan could be identified with suitable Sens/NPV for clinical use. A clinical algorithm to identify patients for Pan-Scan, using a combination of physical exam findings and specific high-risk criteria, was identified and had a Sens of 0.94 and NPV of 0.86 This rule would have identified injuries in all but 90 patients (1.6%) and would theoretically spare 11.9% (655) of blunt trauma patients a torso CT. CONCLUSIONS: Our findings advocate for Head/Cspine CT in all geriatric patients with the addition of torso CT in the setting of positive clinical findings and high-risk criteria. Prospective validation of this rule could lead to streamlined diagnostic care of this growing trauma population. LEVEL OF EVIDENCE: Level 2, Diagnostic Tests or Criteria.

Recurrent Obturator Hernia: A Rare Entity.

Obturator hernias are rare with an incidence of less than 1% of all hernias and are most common in frail, elderly females. They are difficult to diagnose and even more difficult to repair. They often present with a small bowel obstruction from the incarcerated bowel. We report a case of a recurrent obturator hernia after a laparoscopic repair using a patch of omentum. The recurrence was repaired laparoscopically with a trans-abdominal preperitoneal repair (TAPP) with mesh. Given the rarity of the disease, there is scarce literature on the ideal method of repair, especially in patients with recurrence. However, with recent trends toward minimally invasive preperitoneal mesh hernia repairs for inguinal and ventral hernias, this type of repair should be strongly considered for patients with obturator hernias as well.

Evaluation of Gender Bias Through Autonomy During Laparoscopic Cholecystectomy at a Rural Community General Surgery Residency Program.

OBJECTIVE: Gender bias not only continues to exist in surgical specialties, but in the medical field overall. Despite females graduating from medical schools at the same rate as men, a discrepancy still exists in the number of females pursuing surgical specialties compared to their male counterparts. We hypothesized that surgical training occurring in smaller institutions with close-knit relationships between faculty and residents should decrease the likelihood of gender bias towards females, as measured by perceived autonomy during laparoscopic cholecystectomy. DESIGN: All 17 surgery residents at a community surgery residency program were asked to voluntarily and anonymously complete an investigator-created questionnaire after every laparoscopic cholecystectomy from October 2020 to May 2022. The questionnaire included details regarding overall resident operative experience, case complexity, patient diagnosis, resident autonomy throughout the case, and perceived autonomy compared to their peers. Each respondent estimated their percent autonomy from 0% to 100% during 5 distinct portions of the case, from which, a mean overall percent autonomy was calculated. RESULTS: A total of 233 questionnaires (98 female, 135 male) were completed during the study period, with 8 females and 9 males in the first study year and 7 females and 10 males in the second. Mean overall autonomy was statistically similar between males and females, 71% and 72% respectively (p = 0.967). Case difficulty was not statistically different between males and females (p = 0.445). There was a significant difference in autonomy of all residents with male and female attendings, 67.5% and 80.3%, respectively (p = 0.001), however this did not differ between male and female residents. Eighty-three percent of respondents felt that their level of autonomy was acceptable for their postgraduate year (PGY) level. Over 90 percent of respondents felt their autonomy was not affected by their gender. CONCLUSIONS: There was no significant difference in perceived autonomy between male and female residents during laparoscopic cholecystectomy at our small general surgery residency program. Gender bias did not appear to be a prohibiting factor in the amount of autonomy given to male and female residents.

Generalized Peritonitis Secondary to Perforated Uterine Pyometra.

Generalized peritonitis with sepsis is a common general surgery emergency. The most likely implicated structure for generalized peritonitis with pneumoperitoneum is the gastrointestinal tract with urgent explorative laparotomy being the most definitive treatment. In this particular case, perforated diverticulitis was suspected and upon an exploration of the abdomen, frank pus in the setting of normal colon was noted. Some common differential diagnoses for frank pus in the abdomen include viscus perforation, pancreatic necrosis, gangrenous cholecystitis, or penetrating abdominal trauma. Here, we report a rare occurrence of peritonitis secondary to uterine rupture from pyometra.

Actinomyces Infection Mimicking Esophageal Cancer.

Actinomycosis is a bacterial infection, which rarely affects the esophagus. Our patient presented with persistent acute blood loss anemia and epigastric pain despite previously negative upper endoscopy. He underwent repeat endoscopy a few months later showing what was thought to be malignant esophageal cancer at the gastroesophageal junction; however, the biopsy report revealed chronic inflammation with actinomycosis. This report will discuss the evaluation and management of actinomyces infections as it is important to distinguish infection from malignancy. It is crucial for physicians to be aware of the unusual presentation and ability to mimic malignancy to aid in proper diagnosis and management and therefore the prevention of unnecessary procedures including resection.
