Emphysematous changes in pneumoperitoneum and tension pneumothorax following robot-assisted bronchoscopy: a case report.

Pneumoperitoneum is most commonly caused by perforation of a hollow viscus but can also result as an extension of pneumothorax and/or pneumomediastinum. We present a case of pneumoperitoneum preceded by intraprocedural hemoptysis and tension pneumothorax that developed during transbronchial needle aspiration using robot-assisted flexible bronchoscopy. After stabilization and management of the pneumothorax, diagnostic laparoscopy was performed and revealed no evidence of diaphragmatic or intra-abdominal perforation but showed diffuse emphysematous changes in the gastrohepatic ligament, small and large bowel mesentery, and preperitoneal space. These findings suggest the implication of subserosal and preperitoneal emphysema as the pathophysiological mechanism of pneumoperitoneum and pneumothorax complicating bronchoscopy procedures.

An inguinal hernia 'hard to stomach'.

Inguinal hernias containing the stomach are extremely rare, and have never been described in females. We are reporting the case of a 79 year old female who presented in septic shock with a left inguinal hernia containing the stomach, resulting in gastric perforation and loss of abdominal domain. She underwent emergency exploratory laparotomy with manual reduction of the hernia, wedge resection of the perforated gastric segment, abdominal washout, and closure of the abdominal fascia using biological mesh. She had a complicated but successful postoperative course, and was discharged to a rehabilitation center three weeks after hospital admission.

Malignant Transformation of Nonhealing Ulcer-Basal Cell Carcinoma.

We discuss the rare case of a 72-year-old female with a history of a nonhealing lower extremity ulcer that was biopsied, revealing malignant transformation to basal cell carcinoma (BCC). Although BCC is the most common malignancy worldwide, malignant transformation of nonhealing wounds is more often associated with squamous cell carcinoma. Current literature estimates the rate of BCC arising from venous stasis ulcer to occur between 1.5 and 15%. When diagnosed early, BCC can have cure rates of up to 95%. However, metastatic BCC has a median survival of roughly 8 months. We believe it is important to raise awareness of this rare, but often curable, clinical diagnosis to improve long-term outcomes.

Noninfectious aortitis: A case report.

INTRODUCTION: Noninfectious aortitis has been increasingly reported worldwide with a growing prevalence in western medicine. Attributed to our increasingly diverse population, western surgeons must be vigilant to promptly differentiate these cases from its more common infectious counterpart in order to ensure subsequent appropriate management of these patients. METHODS: We present a case report of a 71-year-old Indo-Caribbean male who presented with nonspecific abdominal and back pain, found to have aortitis of a noninfectious etiology.Results and conclusion: While our patient's process was ultimately managed without surgical intervention, the varied clinical presentation along with the lack of specific laboratory markers pose a challenge for surgeons to appropriately diagnose and manage aortitis. Appropriate diagnostic imaging, the utilization of a multidisciplinary team, and close patient monitoring are key components for effective management of this increasingly prevalent disease process.

Early hemodynamic characteristics of eversion and patch carotid endarterectomies.

OBJECTIVE: Carotid endarterectomy (CEA) is currently the gold standard in the operative management of carotid artery stenosis. While eversion and patch CEAs vary greatly in technique, various studies have determined equivalence with regard to clinical outcomes. However, the hemodynamic differences following each procedure are not known. This study aimed to investigate any early hemodynamic differences between eversion and patch CEAs. METHODS: All CEAs performed at our institution from March 2012 to June 2018 were aggregated in a retrospective database by querying the 35301 CPT code from the electronic medical record system. Variables collected included gender, age, laterality of CEA, type of procedure, and pre- and post-operative duplex ultrasound (DUS) date and quantitative findings. Exclusion criteria included any procedure with incomplete data, a post-operative DUS > 90 days following the procedure, CEAs with concomitant bypass(es), isolated external carotid artery (ECA) endarterectomies, and re-do CEAs. RESULTS: One hundred and seventy-one CEAs were performed in 161 unique patients. There were 101 males and 60 females, with an average age of 69.7 (38-96; ± 9.36). 63 CEAs were excluded from analysis: 51 due to incomplete data, eight with a > 90 day post-operative DUS, 2 isolated ECA endarterectomies, 1 CEA with a carotid-subclavian bypass, and 1 re-do CEA secondary to an infected patch. Twenty-seven eversion and 81 patch CEAs were included in analysis. There was no difference in procedure laterality or gender between the two cohorts (p > 0.05); however, patients who received an eversion CEA were older on average (73.3 vs 67.5; p = 0.002). Pre-operative peak systolic velocities (PSV) of the proximal internal carotid artery (ICA), distal ICA, and distal common artery (CCA) were all similar (p > 0.05). Post-operative DUS was performed at 17.0 and 12.9 days in the eversion and patch CEA cohorts, respectively (p = 0.12). Post-operative PSV and change in PSV were similar for all three aforementioned segments (p > 0.05). CONCLUSION: Although eversion and patch CEAs vary greatly in technique and post-procedure anatomy, there was no significant difference in post-operative PSV or change in PSV at or around the carotid bifurcation.

A unique surgical emergency: ileosigmoid knotting.

Ileosigmoid knot (ISK) is a rare cause of bowel obstruction that leads to gangrenous bowel necrosis. In this condition, the ileum and sigmoid colon wrap around each other, causing a knot and strangulation of both structures. ISK is extremely rare in North America; most cases are reported in Asia and Africa. Furthermore, ISK typically presents in adults in their fourth decade or older. Here we present the rare case of an ISK in a 14-year-old male.
