Introduction: Primary appendiceal cancer with fistula formation is extremely rare. We report a case of a patient with appendiceal cancer invading the ileum who underwent successful laparoscopic ileocecal resection.
Presentation Of Case: A 76-year-old man who presented with fever and abdominal pain was diagnosed with acute appendicitis and received antibiotics at a local hospital. After a few days, he was referred to our hospital because of an abnormality found in the colonoscopy, which was an oozing ulcer in the terminal ileum. Laparoscopic ileocecal resection was performed with a preoperative diagnosis of ileal cancer. The tumor adhered to the right internal inguinal ring. We dissected the right spermatic cord involved in the tumor. The resected specimen revealed a fistula between the appendiceal orifice and ileac ulcer. Histopathological examination revealed a well differentiated tubular adenocarcinoma. We made the diagnosis of appendiceal cancer with an ileal fistula because the ileal ulcer was derived from the appendiceal site.
Discussion: Most cases of appendiceal cancer with a fistula undergo laparotomy, but in selected cases, laparoscopic resection should be considered a feasible, safe, and curative procedure. Our patient underwent laparoscopic ileocecal resection, whereby the tumor and other organs with invasion were resected successfully with a negative surgical margin.
Conclusion: This is the first case report of appendiceal cancer with an ileal fistula successfully treated with laparoscopic resection. Laparoscopic ileocecal resection can be applied for appendiceal cancers with a fistula by experienced surgeons with careful consideration.

A 54-year-old woman was referred to our hospital because of abnormal colonoscopic findings, including a submucosal protuberance at the appendiceal root. A biopsy showed no malignant findings. Computed tomography revealed a 20-mm cystic lesion with thick walls at the appendiceal root, suggestive of an appendiceal mucocele.

Blunt abdominal trauma causing intraperitoneal injury and/or bleeding can be life-threatening, requiring immediate intervention. Diagnosing these cases can be challenging, especially when pre-existing conditions are involved. Low-grade appendiceal mucinous neoplasm (LAMN) is a rare tumor of the appendix that can lead to pseudomyxoma peritonei.

First-bite syndrome (FBS) is manifested as acute and severe pain in the parotid region occurring at the first bite of a meal. While most cases of FBS arise after surgeries involving the deep lobe of the parotid gland, chemotherapy-induced FBS is extremely rare. Some adverse effects of oxaliplatin resemble FBS, suggesting it may be under-recognized.

Article Synopsis
- National guidelines recommend segmental colectomy for appendiceal neuroendocrine neoplasms larger than 2.0 cm due to risks of lymph node involvement, with conditional overall survival becoming an important prognostic tool.
- A study of 3,541 patients revealed that 16% had positive lymph nodes, and factors like size, depth of invasion, and lymphovascular involvement were correlated with metastasis.
- The findings suggest that more clinicopathologic factors should influence decisions on surgical treatment and surveillance for better survival rates, especially for patients with more aggressive histologies.

Introduction: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is increasingly performed in young patients with peritoneal surface malignancies. Important quality of life (QoL) questions arise; however, there is limited research on fertility experiences in young women with carcinomatosis or following CRS/HIPEC.
Methods: Retrospective review of a prospective database evaluating women less than 45 ys who underwent CRS/HIPEC at the University of Pittsburgh Medical Center from January 1998 to 2020.
