Delayed esophageal anastomotic complication and ramucirumab therapy: A case report.

Current NCCN guidelines for second-line therapy in recurrent or metastatic esophago-gastric cancers recommend the use of VEGF inhibitors such as ramucirumab. VEGF inhibitors have been shown to be associated with gastrointestinal perforation in clinical trials and late colorectal anastomotic leaks in a few case reports. Here, we present a case of late esophageal anastomotic leak in a patient receiving ramucirumab. Case information was obtained from our institution's electronic medical records. The patient was found to have T4N1M0, poorly differentiated invasive adenocarcinoma and subsequently received neoadjuvant chemoradiation followed by hybrid Ivor-Lewis esophagectomy 6 weeks later. He recovered well with no leak or perioperative complications. The patient had disease progression 9 months postoperatively on CT and PET imaging. Sixteen months after surgery he began paclitaxel and ramucirumab and 16 weeks after ramucirumab initiation, he was found to have an esophago-pulmonary fistula in the region of the anastomosis. Biopsies were negative for recurrence at the anastomosis. He died one week later from progressive pneumonia despite stenting. In conclusion, this is the only known report of delayed esophageal anastomotic complication associated with ramucirumab. VEGF inhibitor therapies such as bevacizumab have been associated with late (greater than 3 months postoperative) colorectal anastomotic complications including fistulas and leaks. Risk factors that have been associated are perioperative radiotherapy and history of early postoperative leak. These findings raise concern whether VEGF inhibitor therapy should be used in post-esophagectomy patients with recurrence if these rare but catastrophic events are likely to be terminal.

Modified Manouguian technique for aortic root enlargement: A case series.

BACKGROUND: Manouguian aortic root enlargement (ARE) has been a standard root enlargement procedure to assist in patients with a small annular size. We describe a modification to the Manouguian ARE similar to Yang et al. This approach could serve as an alternate technique for performing ARE; to date only case reports have defined this approach and no studies have evaluated its efficacy or safety. METHODS: A retrospective case series was performed on patients who underwent ARE for surgical aortic valve replacement via the modified Manouguian procedure at a single institution. Thirteen patients were identified between 2015 and 2021, and all surgeries were performed by a single operator. Data were collected via the Society of Thoracic Surgeons database and chart review. The primary outcome was difference in valve size after the procedure. RESULTS: The most common indication for surgery was aortic stenosis (12, 92%), with the most common etiology being degenerative calcification (7, 54%). Congenital bicuspid or unicuspid valves were identified in five (38%) patients. The majority (10, 77%) of patients received a mechanical valve. This procedure was successfully performed in all 13 of the patients. Additionally, 13 of the 13 patients (100%) were upsized to a satisfactory valve size based on preoperative echocardiography sizing. CONCLUSIONS: The modified Manouguian aortic enlargement technique can be safely and effectively used as an aortic enlargement procedure in a broad sample of patients.

The use of grape juice in the detection of esophageal leaks.

BACKGROUND: Esophagectomies and repair of esophageal perforations are operations used for a variety of clinical indications. Anastomotic leaks are a major post-operative complication after these procedures. At our institution, we routinely use grape juice to detect esophageal leaks in the post-operative setting in addition to other standard imaging modalities. We hypothesize that grape juice can provide similar diagnostic sensitivity and specificity to other modalities for leak detection. METHODS: A retrospective review of all patients who underwent an esophagectomy or repair of esophageal perforations from 2013-2019 by the thoracic surgery service at our institution was performed. All patients underwent a barium swallow study, CT imaging or upper endoscopy, as well as ingesting purple grape juice on post-operative day 5 or greater. Purple grape juice observed in the tube thoracostomy drainage system was identified as a positive esophageal leak. RESULTS: Sixty-four patients were included in the study period (25% female, 88% white, median age 62 years old). Sixty-three patients had both a barium swallow study and grape juice test, while one patient underwent CT imaging and grape juice study. Grape juice test sensitivity and specificity were found to be 80% and 98.3%, respectively. CONCLUSIONS: This pilot study demonstrates the effectiveness of using grape juice in detecting esophageal leaks after esophageal operations in patients with tube thoracostomies. Grape juice may be cheaper and potentially less morbid than other studies performed to detect esophageal leaks. Further research is needed to justify the increased use of grape juice in patients who undergo esophageal operations.

A Comparison of Sphenoid Sinus Osteoneogenesis in Aspirin-Exacerbated Respiratory Disease.

BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) is characterized by excessive leukotriene production, diffuse polyp burden and osteitic bone changes. These bony changes have not been previously characterized. OBJECTIVE: The aim of this radiographic study is to characterize the bony changes noted on computed tomography (CT) scans of the sphenoid sinus in patients with AERD compared to other diseased sinonasal inflammatory states and non-diseased controls. METHODS: A retrospective review of 43 patients with clinically confirmed AERD were included and compared to 22 non-diseased, 9 allergic fungal sinusitis, and 43 chronic rhinosinusitis controls (23 without polyps and 18 with polyps). Comparative measurements were performed using fine-cut CT scans. Sites of comparison were the intersinus septum, the left and right lateral sphenoid wall, the roof, and left and right floor of the sphenoid sinus. Standardized measurements were averaged by two separate rhinologists. RESULTS: Patients with AERD had an average statistically significant increase in bone thickness compared to healthy and diseased controls in nearly every site with the most pronounced changes in the intersinus septum (p < 0.05). CONCLUSION: Patients with AERD have significantly increased thickness of the sphenoid bone compared to control groups with the most pronounced difference in the intersinus septum. These findings may help clinicians increase suspicion for a diagnosis of AERD who clinically have diffuse nasal polyposis.

Nasopharyngeal Hyalinizing Clear Cell Carcinoma: A Case Report and Review of the Literature.

BACKGROUND: Hyalinizing clear cell carcinomas (HCCCs) are rare, low-grade, malignant tumors which most often arise from the minor salivary glands primarily in palate and tongue but can arise in any location with minor salivary glands including the nasopharynx. METHODS: A case report of primary nasopharyngeal HCCC is presented. Because of the rarity of this tumor and location, a literature search was conducted to determine the most common presenting symptoms, treatment strategies, and outcomes. RESULTS: A 48-year-old man underwent biopsy of a 4.5 cm mass of the right nasopharynx with pathology suggesting an intermediate grade mucoepidermoid carcinoma. After discussing management with the patient, an endoscopic resection was performed. Final pathology revealed an HCCC which was confirmed after negative Mastermind-like 2 (MAML2) and positive Ewing sarcoma breakpoint region 1 (ESWR1) gene rearrangements on fluorescence in situ hybridization (FISH) studies. Literature review of other nasopharyngeal HCCC cases shows diverse presentation and overall excellent prognosis through surgical and radiation therapy. CONCLUSION: HCCCs are rare, low-grade malignant tumors of the minor salivary glands and can present as a nasopharyngeal mass. Presenting symptoms are diverse but frequently involve otologic and sinonasal disturbances. HCCC is an indolent tumor with an excellent prognostic outcome when treated appropriately with surgical resection and adjuvant radiotherapy.
