Obturator Hernia, 'The Little Old Lady Hernia'.

Obturator hernia is a rare type of abdominal hernia that classically presents in elderly women. We report the case of 78-year-old woman with progressive vomiting, obstipation, and abdominal pain. Contrast-enhanced computed tomography showed a left-sided obturator hernia, which was confirmed and treated at laparotomy. Demographics, symptoms, imaging findings, and management of obturator hernias is reviewed.

Jejunal Carcinoid Tumors Presenting as Small Bowel Obstruction.

Carcinoid tumors are the most common form of gut neuroendocrine tumors, however, they rarely present with small bowel obstruction. We present a case of a 65-year-old woman without prior abdominal operations who presented with symptoms of small bowel obstruction. Computed tomography (CT) showed multiple air fluid levels and a transition point in the left mesentery with two soft tissue densities at the same level. The patient was taken to the operating room for surgical exploration, which showed two intramural masses in the mid and distal jejunum, which surgical pathology showed to be stage IIIB carcinoid tumor.

Distance of the internal central venous catheter tip from the right atrium is positively correlated with central venous thrombosis.

Central venous catheters (CVCs) are associated with occlusive, infectious, and thrombotic complications. The aim of this study was to determine if internal CVC tip position was correlated with subsequent complications. This was an institutional review board approved single-center retrospective review of 169 consecutive patients who underwent placement of 203 semipermanent CVCs. Using post-placement chest X-rays, a de novo scale of internal catheter tip position was developed. Major complications were recorded. A logistic regression analysis was used to determine if catheter tip position predicted subsequent complications. There were 78 men and 91 women with a mean age of 48 ± 11 years. There were 21 catheter tips placed in the subclavian/innominate veins, 32 in the upper superior vena cava, 113 in the atriocaval junction, and 37 in the right atrium. There were 83 complications occurring in 61 (36.1 %) patients, including sepsis in 40 (23.7 %), venous thrombosis in 18 (10.7 %), catheter occlusion in 16 (9.5 %), internal catheter repositioning in 6 (3.6 %), pneumothorax in 2 (1.2 %), and death in 1 (0.6 %). An internal catheter tip position peripheral to the atriocaval junction resulted in a catheter that was more likely to undergo internal repositioning (p < 0.001) and venous thrombosis (p < 0.001). Patients with femoral catheters were more likely to develop sepsis (45 %) than patients whose catheters were inserted through the upper extremity veins (18 %) (p < 0.01). In conclusion, to reduce catheter-associated morbidity and potentially mortality, the internal catheter tip should be positioned at the atriocaval junction or within the right atrium and femoral insertion sites should be avoided whenever possible.

Acquired post-traumatic aortic coarctation presenting as new-onset congestive heart failure: treatment with endovascular repair.

Acquired coarctation of the thoracic aorta is a rare phenomenon in adults. The etiology is often idiopathic, but severe stenosis can develop from prior surgery, blunt thoracic aortic injuries, or severe atherosclerotic/atheroembolic disease. Common symptomatic presentations include refractory upper extremity hypertension and new-onset congestive heart failure. We present the case of a 52-year-old man who developed acquired thoracic aortic coarctation 30 years after a blunt trauma and deceleration injuries to the aorta requiring open surgical aortic repair. He presented with poorly controlled hypertension and new-onset heart failure and was treated surgically with endovascular repair.

Penetrating thoracic injury requiring emergency pneumonectomy supported with two ECMO runs: A testament to multidisciplinary critical care medicine.

Post-traumatic pneumonectomies are uncommon and, if necessary, carry significant mortality. The use of extracorporeal membrane oxygenation (ECMO) for lung injury in trauma patient has demonstrated efficacy with minimal bleeding complications. We report a case of a young man with a penetrating thoracic injury that required a pneumonectomy supported with two separate ECMO runs for pulmonary failure postoperatively.

Traumatic bilateral carotid artery dissection.

INTRODUCTION: Bilateral carotid artery dissection following blunt trauma is a rare but potentially lethal injury if not diagnosed early and treated. CASE REPORT: We report a collision patient who suffered bilateral asymptomatic carotid artery dissections. He also had multiple fractures of the pelvis and upper and lower extremities. The patient was managed acutely with aspirin. He underwent open reduction and internal fixation of fractures without complication and was discharged home on aspirin. DISCUSSION: Carotid artery dissections are increasingly being recognized in blunt trauma patients. Management options include systemic anticoagulation versus antiplatelet therapy. The need to acutely address the carotid artery injury must be balanced with the need for hemostasis with associated solid organ injury and/or future operative procedures. CONCLUSIONS: Carotid artery dissections should be screened for in patients with appropriate mechanism of injury. This case report details the successful management of a patient of bilateral carotid artery dissection and other major orthopedic injuries using aspirin.

Appendectomy Hospital Stay: No Difference in Obese Adult or Pediatric Patient Length of Stay Compared to Nonobese Patients.

Background: Studies of adult and pediatric patients undergoing appendectomy have reported variable outcomes and operative metrics related to the effect of obesity. The purpose of this study was to investigate the effect of obesity in adult and pediatric patients undergoing appendectomy at our institution. Methods: This single-center retrospective study evaluated the relationship between length of hospital stay for appendectomy and body mass index (BMI). Data obtained from the electronic medical record included age, sex, weight, height, BMI, the number of hours the patient experienced symptoms prior to presentation to the emergency room, the number of hours the patient was admitted prior to surgery, the number of hours of hospital admission after surgery, perforated appendix, preoperative comorbidities, and evidence of preoperative sepsis. Results: During the 3-year study period, 118 adults and 38 children who underwent appendectomy composed the study groups. Patients were stratified by obese and nonobese, with obesity defined as BMI ≥30.0 kg/m2. In adults, we found no significant difference between length of stay in obese (n=45) and nonobese (n=73) patients (79.6 ± 65.5 hours vs 101.6 ± 123.0 hours; P=0.21). In children, we found no significant difference between length of stay in obese (n=9) and nonobese (n=29) patients (92.9 ± 64.6 hours vs 109.0 ± 93.5 hours; P=0.54). Conclusion: Obesity did not affect length of stay in adults and children who underwent appendectomy in the present series.

Lazarus phenomenon in trauma.

Lazarus phenomenon embodies auto-resuscitation, aka the return of spontaneous circulation following termination of cardiopulmonary resuscitation. Limited or no literature exists that describes auto-resuscitation in trauma. In the current report, we describe a case of an older woman that presented with poly-traumatic injuries following a motor vehicle collision. The aggressive resuscitation efforts failed, and the patient witnessed a pulseless electrical activity; however, nine-minutes after cessation of resuscitation efforts, the patient experienced auto-resuscitation. In addition to the sequel of events following the presentation, the report highlights the management dilemma and ethical implications relating to the observation period for auto-resuscitation in cases of donation after circulatory death, where the urgency to harvest the organs to ensure maximum viability is in direct opposition to ensuring enough time has elapsed to rule out auto-resuscitation. Guidelines on an appropriate period for observation in auto-resuscitation patients queued for organ donation are warranted, keeping in lieu viability of organs following death.

Acute splenic rupture following laparoscopic pneumoperitoneum: A case report.

INTRODUCTION: Splenic rupture after laparoscopic surgery is a very rare complication. In this study, we report a case of a splenic laceration that occurred during a laparoscopic gastrostomy tube placement. The theorized mechanism in this case was acute disruption of a peri-splenic hematoma. CASE REPORT: A 64-year-old African-American male presented after a motor vehicle accident with multiple injuries and was admitted to a surgical intensive care unit, where he declined from ICU days 6 through 11. The patient underwent tracheostomy and laparoscopic gastrostomy tube placement given his significant neurologic deficits. Intraoperatively, the patient developed hypotension, leading to the discovery of hemoperitoneum and necessitating an emergent open splenectomy. CONCLUSION: Splenic rupture following laparoscopic procedures is a very rare phenomenon. In this case, we believe the splenic rupture was secondary to an acute disruption of a previously hemostatic splenic hematoma involving the abdominal wall during creation of capnoperitoneum.

Comparing Surgical Site Infection for Open and Endoscopic Component Separation.

In March 2016, we reported the SSI rate at LSU Health for all abdominal wall hernia repairs performed between 2011 and 2013. Among the 263 repairs, the infection rate averaged 6.8 per cent. Given the diversity of repairs, this global percentage lacks relevance, but looking at subsets provides meaningful insights. For example, SSI was 1.8 per cent among 55/263 laparoscopic repairs and 8.2 per cent among 206/263 open repairs. The infection rate of 26.3 per cent among the 19 open component separation cases was especially noteworthy and bothersome. Even though there was no mortality in any subset, the vast majority of the morbidity and costs involved repairs with open component separations. A meta-analysis published in 2016 revealed a likely SSI benefit for the endoscopic component separation technique (ECST) over the open CST. Since that report, we have focused our quality improvement efforts on this subset of challenging cases and have replaced CST with ECST. Our data now include results from 33 hernia repairs with either CST or ECST that were performed between November 2011 and April 2018. Twenty-four of 33 patients had CST with an SSI rate of 37.5 per cent (9 of 24). Nine of 33 had ECST with 0 per cent SSI (P value = 0.039). These results mirror the findings reported in the meta-analysis.

Prophylactic Antibiotics for Elective Laparoscopic Cholecystectomy.

Surgical site infections with elective laparoscopic cholecystectomy are less frequent and less severe, leading some to suggest that prophylactic antibiotics (PA) are no longer indicated. We compared the incidence of surgical site infections before and after an institutional practice change of withholding PA for elective laparoscopic cholecystectomy. Between May 7, 2013, and March 11, 2015, no PA were given to patients selected for elective cholecystectomy by two surgeons at a single center. The only patients excluded were those who received antibiotics before surgery for any reason. All others, including those at high risk for infection, were included. The incidence and severity of infections were compared with historical controls treated with prophylaxis by the same two surgeons from November 6, 2011, to January 13, 2013. There were 268 patients in the study group and 119 patients in the control group. Infection occurred in 3.0 per cent in the study group compared with 0.9 per cent in the controls (P = 0.29). All infections were mild except one. Based on these data, the routine use of PA for elective laparoscopic cholecystectomy is not supported.

Occult lawn mower projectile injury presenting with hemoptysis.

We present the case of a 72-year-old man with hemoptysis after a thoracic projectile injury, which occurred while mowing the lawn. Chest radiograph followed by a computed tomography angiogram revealed a metallic foreign body in the right middle lobe of the lung. The patient underwent a right anterolateral thoracotomy where the object was successfully retrieved. The patient had an uneventful postoperative recovery.

Impact of Prehospital Transportation on Survival in Skiers and Snowboarders with Traumatic Brain Injury.

INTRODUCTION: Prehospital helicopter use and its impact on outcomes in snowboarders and skiers incurring traumatic brain injury (TBI) is unknown. The present study investigates the association of helicopter transport with survival of snowboarders and skiers with TBI, in comparison with ground emergency medical services (EMS), by using data derived from the National Trauma Data Bank (2007-2014). METHODS: Primary and secondary endpoints were defined as in-hospital survival and absolute risk reduction based upon number needed to transport (treat) respectively. Multivariable regression models including traditional logit model, model fitted with generalized estimating equations, and those incorporating results from propensity score matching methods were used to investigate the association of helicopter transport with survival compared with ground EMS. RESULTS: Of the 1018 snowboarders and skiers who met the criteria, 360 (35.4%) were transported via helicopters whereas 658 (64.6%) via ground EMS with a mortality rate of 1.7% and 1.5%, respectively. Multivariable log-binomial models demonstrated association of prehospital helicopter transport with increased survival (odds ratio 8.58; 95% confidence interval 1.09-67.64; P = 0.041; absolute risk reduction: 10.06%). This finding persisted after propensity score matching (odds ratio 24.73; 95% confidence interval 5.74-152.55; P < 0.001). The corresponding absolute risk reduction implies that approximately 10 patients need to be transported via helicopter to save 1 life. CONCLUSIONS: Based on our robust statistical analysis of retrospective data, our findings suggest prehospital helicopter transport improved survival in patients incurring TBI after snowboard- or ski-related falls compared with those transported via ground EMS. Policies directed at using helicopter services at remote winter resorts or ski or snowboarding locations should be implemented.

Atraumatic splenic rupture and ileal volvulus following cocaine abuse.

We present the case of a 38-year-old male with an atraumatic splenic rupture, hemoperitoneum, and ileal volvulus following acute cocaine intoxication. Computed tomography showed a "whirl sign", a subcapsular splenic hematoma with suspected peripheral laceration, and diffuse hemoperitoneum. At laparotomy, the spleen was confirmed to be the source of bleeding and was removed. A nonreducible volvulus was found at the distal ileum, and this segment of small bowel was removed. The patient had an uneventful postoperative recovery.

Repair of Large Sliding Inguinal Hernias.

Sliding inguinal hernias are often unexpected intra-operative findings, and repair of which can be technically challenging. A number of repair techniques have been described. The author modified a technique based on an approach described by Bevan. The purpose of our study is to describe this modified Bevan technique for repair of sliding inguinal hernias and report its efficacy in a series of patients. We retrospectively reviewed all patients with open inguinal hernia repairs performed by a single surgeon from August 2007 to April 2013 for sliding indirect hernias using the modified Bevan technique. Patient records were reviewed for demographics, hernia characteristics, complications, admission status, length of stay, and complications. There were 25 patients eligible for our review (male = 25, mean age = 49 years). All sliding hernias were indirect, none were bilateral, and two were incarcerated. The sliding component involved the bladder and perivesical fat (n = 12), sigmoid colon (n = 10), and the cecum and appendix (n = 3). Eighteen patients were treated as outpatients; seven patients were admitted with a mean stay of 2.2 days. Complications included intra-operative bleeding (n = 1), subcutaneous wound hematoma (n = 1), scrotal seroma (n = 1), transient orchialgia (n = 1), and ileus (n = 1). All patients were seen postoperatively for short-term follow-up with no hernia recurrences. Thirteen patients were available for long-term follow-up (mean = 13.6 months); all had no hernia recurrences. The modification of Bevan's technique for repair of large sliding hernias worked well in our series.
