Appropriate timing for the removal of urinary catheters in gastrointestinal surgery with epidural anesthesia: a randomized controlled trial.

Purpose: The purpose of this randomized controlled trial was to evaluate whether early urinary catheter removal is feasible during epidural anesthesia during gastrointestinal surgery in male patients at high risk for urinary retention.

Methods: Male patients who underwent radical surgery for gastric or colon cancer were enrolled in this randomized controlled trial. Patients were randomized 1:1 into 2 groups: the early group, in which the urinary catheter was removed before removal of the epidural catheter on the second or third postoperative day, and the late group, in which the urinary catheter was removed after removal of the epidural catheter.

Radiological Cutoff Values for Diagnosis of Lymph Node Metastasis in Colorectal Cancer With Multilevel Analysis.

Background/aim: A cutoff value for lymph node diameter in colorectal cancer lymph node metastases has not been established. This prospective study aimed to investigate the direct association between swollen lymph nodes identified on preoperative computed tomography (CT) and pathological findings and proposed a cutoff value.

Patients And Methods: We enrolled patients scheduled to undergo curative surgery with lymph node dissection for colorectal adenocarcinoma who underwent preoperative contrast-enhanced CT and had swollen lymph nodes ≥7 mm in diameter.

Strangulated Bowel Obstruction Due to Hiatal Hernia After Laparoscopic Total Gastrectomy.

Laparoscopic total gastrectomy results in more internal hernias than open surgery. However, there are few reports of incarcerated hiatal hernia after laparoscopic total gastrectomy. Here, we report a case of a 79-year-old male who underwent urgent surgical intervention for a strangulated intestinal obstruction due to an incarcerated hernia through the esophageal hiatus following laparoscopic total gastrectomy.
