The importance of CA 72-4 and CA 19-9 dosing in gastric cancer.

Serological analysis of tumor markers has emerged as a non-invasive method for monitoring cancer patients, including tumor recurrence and response to treatment. Tumor markers have the potential to aid in both the diagnosis and prognosis of cancer, but their most important role currently lies in the monitoring of tumor progression. Tumor markers can also provide valuable information on treatment effectiveness, with changes in plasma values indicating tumor regression or progression.

Endoscopic Pilonidal Sinus Treatment Combined With Crystalized Phenol Application May Prevent Recurrence.

Background: No single treatment yet exists for pilonidal disease that has a short healing time, good cosmetic results, and a low rate of recurrence. Phenol crystal application and diathermy ablation through an endoscope have been used for the treatment of pilonidal disease, but this cohort is the first one to combine them.

Objective: The purpose of this study was to examine the safety, effectiveness, and short- and long-term outcomes of crystalized phenol treatment combined with endoscopic pilonidal sinus treatment for pilonidal disease.

Intraoperatively Testing the Anastomotic Integrity of Esophagojejunostomy Using Methylene Blue.

Background: Intraoperative testing of gastrointestinal anastomosis effectively ensures anastomotic integrity. This study investigated whether the routine use of methylene blue intraoperatively identified leaks to reduce the postoperative proportion of clinical leaks.

Methods: This study retrospectively analyzed consecutive total gastrectomies performed from January 2007 to December 2014 in a university hospital setting by a general surgical group that exclusively used the methylene blue test.

Tubulovillous adenoma in the common bile duct causing obstructive jaundice.

Villous adenomas are benign epithelial lesions with a malignant potential which can occur at any site in the gastrointestinal tract, usually in the rectum and colon, less frequently in the small bowel and very rarely in the biliary tract. Villous adenomas of the extrahepatic bile ducts are exceptional and only a few cases have been reported. Common bile duct (CBD) adenomas often present in a fashion similar to their malignant counterparts, and adenocarcinoma arising from a villous adenoma of the ampullary biliary epithelium is also extremely rare.
