Investigating factors associated to dysphagia and need for percutaneous endoscopic gastrostomy in patients with head and neck cancer receiving radiation therapy.

In this study we sought to investigate factors associated to dysphagia and subsequent need for percutaneous gastrostomy (PEG) usage, in patients with head and neck cancer receiving radiation therapy. The records of 123 patients with non-metastatic, stage I-IV head and neck cancer who were submitted to radiation therapy were retrospectively reviewed. Logistic regression models were used to investigate for associations between the outcomes of interest (grade ≥2 dysphagia and need for [PEG] usage) and potential predictive factors.

Role of minimally invasive surgery in the treatment of gallbladder metastatic melanoma. A review of the literature and a case report.

Background: Primary and secondary gallbladder melanomas are rare, and only 58 cases have been reported in scientific literature to date. This paper aimed to explore the role of minimally invasive surgery in the management of gallbladder metastatic melanomas.

Case: Herein, we present the case of a 68-year-old man with metastatic gallbladder melanoma who was treated with laparoscopic cholecystectomy.

Infarcted ligamentum teres hepatis lipoma mimicking acute abdomen in a female patient: a case report and mini-review of the literature.

Lipomas of the ligamentum teres hepatis are extremely uncommon. There have been only a few cases reported in the literature, including lipomas of the falciform ligament of the liver. Here we report a case of torsion and infarction of a lipoma of the ligamentum teres hepatis in a 43-year-old female patient, who presented with acute epigastric pain, nausea and vomiting.

Metastatic spread of cutaneous melanoma to the sigmoid colon: a rare but important consideration.

Background: Cutaneous melanoma is known for its aggressive tendency for metastasis, most commonly to lymph nodes, lung, liver, and brain.

Case Report: We present the case of an 80-year-old male, with a history of cutaneous melanoma, found to have biopsy-proven metastatic melanoma deposits in the sigmoid colon. This rare case was initially thought to be a walled-off perforation secondary to diverticulitis.
