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.

A comparison of robotic enhanced-view totally extraperitoneal approach versus trans-abdominal retro-muscular approach for midline ventral hernias.

BACKGROUND: The evolution of midline ventral hernia repair has progressed from the open Rives-Stoppa technique to minimally invasive robotic approaches, notably the trans-abdominal retromuscular (TARM) and enhanced-view Totally Extraperitoneal (eTEP) methods. This study compares these two robotic techniques in repairing medium-sized midline ventral hernias. METHODS: A retrospective comparative study of electronic medical records from 2015 to 2021 was conducted on patients undergoing robotic TARM or eTEP at NYU Langone Hospital-Long Island. Data on demographics, comorbid conditions, surgical history, intraoperative details, hernia characteristics, and postoperative outcomes were analyzed. RESULTS: Both eTEP and TARM groups exhibited comparable outcomes regarding operative duration, hernia defect size, and overall complications. However, notable differences were observed in patients' BMI, implanted mesh area, mesh composition, and fixation techniques across the groups. The TARM group required a longer hospital stay (median: 1 day) in contrast to the eTEP group (median: 0 days). Additionally, eTEP patients indicated reduced postoperative pain scores (median: 2) compared to TARM (median: 3), with both differences being statistically significant (p < 0.001). CONCLUSION: The robotic eTEP approach is associated with lower post-operative pain scores, decreased hospital length of stay, and larger areas of mesh implantation as compared to the TARM approach. Other variables are largely comparable between the two techniques. LEVEL OF EVIDENCE: Level III.

Trends in gastric surgery operative experience among general surgery residents in the United States: A nationwide retrospective analysis.

BACKGROUND: Gastric surgery is a crucial component of general surgery training. However, there is a paucity of high-quality data on operative volume and the diversity of surgical procedures that general surgery residents are exposed to. METHODS: We conducted a retrospective analysis of operative case logs of all general surgery residents graduating from the American College of Graduate Medical Education-accredited program from 2009 to 2022. Data on the mean number of gastric procedures, including the mean in each subcategory, were retrieved. A Mann-Kendall trend test was used to investigate trends in operative volume. RESULTS: Between 2009 and 2022, the mean overall logged gastric procedures rose significantly (τ = 0.722, P < .001) from 36.2 in 2009 to 49.2 in 2022 (35.9% increase). The most substantial growth was seen in laparoscopic gastric reduction for morbid obesity (mean 1.9 in 2017 to 19 in 2022; τ = 0.670, P = .009). A statistically significant increase was also seen in laparoscopic partial gastric resections, repair of gastric perforation, and "other major stomach procedures" (P < .05 for all comparisons). Open gastrostomy, open partial gastric resections, and open vagotomy all significantly decreased (P < .05 for all comparisons). There was no significant change in the volume of laparoscopic gastrectomy, total gastric resections, and non-laparoscopic gastric reductions for morbid obesity (P > .05 for all comparisons). CONCLUSION: There has been a substantial increase in the volume of gastric surgery during residency over the past 14 years, driven mainly by an increase in laparoscopic gastric reduction. However, there may still be a need for further gastric surgical training to ensure well-rounded general surgeons.

Predictors of Length of Hospital Stay After Reduction of Internal Hernia in Patients With a History of Roux-en-Y Gastric Bypass.

BACKGROUND: Postoperative internal hernias after Roux-en-Y gastric bypass (RYGB) have an incidence of 2%-9% and are a surgical emergency. Evidence on factors associated with length of stay (LOS) after emergent internal hernia reduction in RYGB patients is limited. METHODS: This is a retrospective review of patients who underwent internal hernia reduction after RYGB at our tertiary care center over a 5 year period from 2015 to 2020. Demographics, comorbidities, and intra- and postoperative hospital course were collected. Univariate and multivariate linear regressions were used to investigate factors associated with LOS. RESULTS: We identified 38 patients with internal hernia after RYGB. These patients with mean age 44.1 years were majority female (71.1%) and white race (60.5%). Of the 24 patients where the RYGB was done at our institution, the mean RYGB to IH interval was 43 months. Petersen's defect (57.8%) followed by jejuno-jejunal mesenteric defect (31.6%) were the most common locations for IH. Both Petersen's and jejuno-jejunal mesenteric hernias were found in 4 cases (10.5%). Revision of bypass and small bowel resection were required in 13.2% and 5.3% of cases, respectively. The median (interquartile range) length of stay (LOS) was 2 days. On the multivariate analysis, male sex (P = .019), conversion to exploratory laparotomy (P = .005), and resection of small bowel (P < .001) were independent risk factors for increased LOS. CONCLUSION: The most common location of IH after RYGB is Petersen's defect, followed by jejuno-jejunal mesenteric defect. LOS was significantly associated with male sex, exploratory laparotomy, and resection of small bowel.

Single-Incision Laparoscopic Cholecystectomy Using the Marionette Transumbilical Approach Is Safe and Efficient with Careful Patient Selection: A Comparative Analysis with Conventional Multiport Laparoscopic Cholecystectomy.

Objectives The "marionette technique" for transumbilical laparoscopic cholecystectomy (m-TLC) offers improved cosmesis and possibly shorter postoperative recovery for patient undergoing laparoscopic cholecystectomy versus the four-port conventional laparoscopic cholecystectomy (CLC). We compared the outcomes of m-TLC and CLC at a tertiary care facility in New York. Methods A retrospective chart review was conducted and data on patients who underwent m-TLC and CLC were retrieved. Hospital length of stay (LOS), operative time, and complications were compared between the two groups using linear and logistic regression, as appropriate. Results M-TLC group patients were significantly younger, predominantly females with lower body mass index. They were less likely to have previous abdominal surgery and more likely to have noninflammatory pathology ( p < 0.05 for all). Nonadjusted LOS (1 vs. 3 days, p -value < 0.0001) and operative time (50 vs. 56 minutes, p -value = 0.007) were significantly lower among patients who underwent m-TLC; however, there was no significant difference on multivariate analysis. In multivariate analysis, there was no difference in the overall complication rate (odds ratio: 1.63; 95% confidence interval 0.02-2.39). Conclusion With careful patient selection, m-TLC offers better cosmesis with comparable safety outcomes. Level of evidence Level III.

Nutcracker phenomenon secondary to superior mesenteric artery syndrome.

Superior mesenteric artery (SMA) syndrome, compression of the duodenum due to a decreased angle between the aorta and SMA, has a wide range of clinical presentations making it difficult to diagnose. Compression of the left renal vein is known as Nutcracker syndrome. We present the case of a 26-year-old male with a delayed diagnosis of SMA syndrome and Nutcracker phenomenon due to the patient's history of chronic pancreatitis. As a result of his obstruction and aspiration pneumonia, he was diagnosed with septic shock. The patient was treated for septic shock and maintained on an enteric diet with improvement in the body mass index and complete resolution of SMA syndrome symptoms.

Lateral hernia secondary to colorectal submucosal resection repaired by robotic-assisted approach: Case report.

INTRODUCTION AND IMPORTANCE: Lateral abdominal wall defects are a rare event and commonly result from iatrogenic causes and trauma. We report the first known case of flank hernia after endoscopic submucosal resection of a colonic polyp complicated by colonic perforation. CASE PRESENTATION: This is a case of a 50-year-old male who underwent endoscopic colonic resection complicated by perforation of the colon. Eight months later, he presented with an enlarging, asymptomatic left flank bulge. CT showed a large flank hernia which was successfully repaired using a robotic transabdominal preperitoneal (TAP) approach. CLINICAL DISCUSSION: The hypothesis is that the endoscopic resection with colonic perforation caused an iatrogenic injury to the abdominal wall creating a lateral abdominal hernia. Injury to abdominal wall musculature may take months to develop into a clinically apparent hernia. Flank hernias can be successfully repaired using a robotic minimally invasive approach. CONCLUSION: Flank bulge and hernias must be included or at least be considered as consequence of a potential complication from endoscopic colonic perforation. Surgeons and endoscopists must be aware of this potential complication and its latent presentation. This case stresses the importance of long-term outcomes monitoring, particularly with innovative procedures.
