ABSTRACT
Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine neoplasm of the skin that has a high propensity to metastasize. Abdominal metastases of MCC have been described previously though these are typically regional with nodal spread. We report the case of a 60-year-old man with a history of left upper extremity MCC who had resection, radiation therapy, and immunotherapy. He ultimately developed large bowel obstruction from metastatic intraperitoneal implants. A 6 cm mass at the descending colon was biopsied and proven to be metastatic MCC. The tumor eroded through the wall of the colon and perforated, requiring emergent colectomy for septic shock. Herein, we describe the first case of colonic perforation secondary to metastatic MCC. This case illustrates the importance of expedient and multifactorial management of patients with rapidly growing metastatic colonic tumors that are at risk for perforation.
ABSTRACT
Formal communication of end-of-life preferences is crucial among patients with metastatic cancer. Our objective is to describe the prevalence of advance directives (AD) and do-not-resuscitate (DNR) orders among stage IV cancer patients with acute care surgery consultations, and the associated outcomes. This is a single institution retrospective review over an eight-year period. Two hundred and three patients were identified; mean age was 55.3 ± 11.4 years and 48.8 per cent were male. Fifty (24.6%) patients underwent exploratory surgery. Nineteen (10.6%) patients had another type of surgery. Twenty-one (10.3%) patients had a DNR order, and none had an AD on-admission. Fifty-four (26.6%) patients had a DNR order placed and four (2%) patients completed an AD postadmission. DNR postadmission was associated with the highest mortality at 42.6 per cent compared with 14.3 per cent for DNR on-admission and 1.56 per cent for full-code patients (P < 0.001). Compared with patients that remained full-code and those with DNR on-admission, DNR postadmission was associated with longer length of stay (19.6 days; P < 0.001) and ICU length of stay (7.72 days; P < 0.001). The prevalence of AD and DNR orders among stage IV cancer patients is low. The higher in-hospital mortality of patients with DNR postadmission reflects the use of DNR orders during clinical decline.

Introduction. A patent urachus is a rare congenital or acquired pathology, which can lead to complications later in life. We describe a case of urachal cystitis as the etiology of small bowel obstruction in an adult without prior intra-abdominal surgery. Case Report. A 64-year-old male presented to the acute care surgery team with a 5-day history of right lower quadrant abdominal pain, distention, nausea, and vomiting. He had a two-month history of urinary retention and his past medical history was significant for benign prostate hyperplasia. On exam, he had evidence of small bowel obstruction. Computed tomography revealed high-grade small bowel obstruction secondary to presumed ruptured appendicitis. In the operating room, an infected urachal cyst was identified with adhesions to the proximal ileum. After lysis of adhesions and resection of the cyst, the patient was subsequently discharged without further issues. Conclusion. Although rare, urachal pathology should be considered in the differential diagnosis when evaluating a patient with small bowel obstruction without prior intraabdominal surgery, hernia, or malignancy.
