Successful surgical management of a combined abdominal and thoracic penetrating injury: a case report.

Penetrating rebar injuries are extremely rare occurrences, but they are very life-threatening, particularly when involving the thoracic and abdominal cavities. The surgical approach to these traumatic injuries depends upon the length and diameter of the rebar as well as the path of penetration into the abdominal and thoracic regions. Due to the highly uncommon occurrence of penetrating rebar injuries, there is very limited information and studies pertaining to this topic in the literature. In this case report, we present a 43-year-old male patient sustaining a rebar penetrating injury, with the entry site being the left flank and the exit site being the anterior left chest. Upon arrival, the patient was emergently taken to the operating room and underwent simultaneous exploratory laparotomy and a left thoracotomy. The operation was successful in removing the rebar and the patient survived.

Peritoneal mesothelioma causing small bowel obstruction in COVID-19 positive patient.

Mesothelioma is a disease process that can present in a variety of locations including the pleural, peritoneum and pericardium. Malignant peritoneal mesothelioma has been known to be a particularly aggressive type of tumor. We report a case of a patient who presented with a small bowel obstruction whose pathology revealed peritoneal malignant mesothelioma.

Incidental discovery of goblet cell carcinoid, a rare appendiceal malignancy case report.

Goblet cell carcinoid (GCC) tumor is a rare appendiceal carcinoma that has had several names throughout its history. Often found incidentally on pathology following an appendectomy, treatment includes a right hemicolectomy and possible adjuvant chemotherapy. Survival rate has been shown to be correlated with the histological features. Here, we report a 45-year-old African American male who presented with signs and symptoms consistent with acute appendicitis, but was ultimately diagnosed with GCC. After undergoing a right hemicolectomy, he continues to undergo long-term surveillance with his oncologist. Due to the rarity of this tumor, we describe the history of GCC and our recommendations for surgical and long-term management.

Pseudoaneurysm of the Abdominal Aorta at the Celiac Trunk After Penetrating Trauma.

We report the case of a 33-year-old man who had received multiple gunshot wounds to the abdomen; consequently, he was diagnosed with a traumatic dissection of the abdominal aorta at the level of the superior mesenteric artery (SMA) extending to just below the renal arteries with a posterior pseudoaneurysm of the aorta. He had wounds in the right upper quadrant and in the left lower back. He demonstrated signs of peritonitis for which he was taken to the operating room for exploratory laparotomy. A right common iliac to SMA bypass with a 7-mm ringed polytetrafluoroethylene (PTFE) graft was created. The celiac trunk was then ligated, and through the right groin sheath, a thoracic endograft stent (Cook Medical, Bloomington, IN) was inserted at the level of the thoracic aorta with resolution of the blood flow to the aorta, visceral and iliac arteries, as well as retrograde flow into the bypass graft. The literature on traumatic abdominal aortic pseudoaneurysm was reviewed, and based on that, we believe this report describes a unique case of a traumatic aortic pseudoaneurysm at the level of the celiac trunk, as well as our operative approach.

Surgical residents' interpretation of diagnostic radiologic imaging in the traumatically injured patient.

BACKGROUND: Senior surgical residents are of paramount importance in directing further therapeutic modalities based on their interpretation of critical diagnostic imaging. We propose that senior surgical residents are proficient with interpreting radiologic imaging studies in the trauma patient. METHODS: A prospective cohort study was performed comparing surgery resident interpretations of computed tomography (CT) scans of the head, maxillofacial bones, spine (cervical, thoracic, lumbar), chest, abdomen, pelvis, and chest X-rays versus final radiologists' reports at a Level II trauma center from September 2014 to May 2015. A Cohen κ coefficient and a statistical analysis of variance testing were used to make multiple comparisons of the data. RESULTS: There were 951 trauma alerts activated in the period stated. Of these, 860 met our age inclusion criteria (age, > 18 years). There were 204 images included with an overall accuracy of 81.3%. Residents were more than 70% successful interpreting seven of nine categories. They achieved an accuracy of 84.6%, 62.5%, and 75% in the cervical, thoracic, and lumbar spine categories, respectively. Forty-one of 50 CT scans of the head were interpreted correctly. Maxillofacial CT scans proved to be the weakest category, with only 50% read accurately. In regard to CT scans of the abdomen and pelvis, 80% proficiency was achieved. Abdominal x-rays were read correctly in all instances and chest x-rays 83.3%. On κ analysis, there was an overall moderate agreement between the two groups with K = 0.449, and an overall p less than 0.0005 (Table 1). A perfect agreement existed with abdominal x-rays. CONCLUSION: Senior surgical residents are capable of interpreting critical images obtained in the trauma setting. When discordance existed with attending radiologists' interpretation, it did not change the clinical outcome or result in any critically missed findings. LEVEL OF EVIDENCE: Therapeutic/Care Management study, Level IV.

Review of nutritional assessment and clinical outcomes in pediatric surgical patients: does preoperative nutritional assessment impact clinical outcomes?

INTRODUCTION: Malnourished adult patients who undergo surgical procedures tend to have worse clinical outcomes compared to well-nourished patients. In the pediatric surgical patient, nutritional assessment is considered a critical aspect of the initial evaluation, but a correlation between preoperative malnutrition and poor surgical outcomes is not clear. We hypothesized that an evidence-based review would reveal that measures of nutritional assessment in children would not correlate pre-operative malnutrition with poor surgical outcomes. MATERIALS AND METHODS: A search of major English language medical databases (Medline, Cochrane, SCOPUS) was conducted for the key words nutritional assessment, pediatric, children, surgery, and outcomes. All methods of nutritional assessment in pediatric surgery were evaluated for their relevance and relation to outcomes after surgery. The Oxford Center for Evidence Based Medicine (CEBM) classification for levels of evidence was used to develop grades of clinical recommendation for each variable studied. RESULTS: 35 articles were evaluated after an exhaustive literature search, of which six met inclusion criteria for this review. There is a paucity of high quality evidence correlating preoperative malnutrition in pediatric surgical patients with clinical outcomes. Factors contributing to the low level of evidence include a lack of high quality randomized controlled trials, a lack of consensus in study design and methods, and utilization of incongruous methods of nutritional assessment, including methods that may be unproven in the study population. CONCLUSION: Larger multi center randomized studies are needed to offer higher level of evidence to support nutritional intervention prior to major elective pediatric surgery.

Three cases of subcutaneous granuloma annulare of the penis: a rare presentation of a common disease.

OBJECTIVE: To describe three patients who presented to a single institution within four years of each other with isolated granuloma annulare of the penis. Granuloma annulare is an inflammatory disease of the dermis that can affect men of any age including childhood. Granuloma annulare of the penis is a remarkably uncommon presentation with only 12 cases previously reported. METHODS: A retrospective review of pathologic records was conducted confirming three cases of penile granuloma annulare diagnosed at our institution. RESULTS: The three cases are described in detail including the history, presentation, histological findings and treatment of each patient. The clinical variants, characteristic histology, classic clinical presentation, differential diagnosis and recurrence following surgery of granuloma annulare are reviewed. CONCLUSION: We describe three individuals from a single institution with isolated granuloma annulare of the penis suggesting this condition is more common than previously thought. Patients with penile granuloma annulare may present to practicing urologists and it is important to be familiar with this idiopathic subcutaneous disorder in order to avoid unnecessary aggressive surgery.
