Reduction of postoperative abdominal adhesion and ileus by a bioresorbable membrane.

Background/aims: This study examines the efficacy of a bioresorbable sodium hyaluronate-carboxy-methylcellulose-based membrane (HA/CMC membrane) in reducing postoperative abdominal adhesion and ileus after intestinal resection. Also, this study attempts to identify the possible factors that influence effectiveness through qualitative analysis of an individual patient case.

Methodology: Bioresorable membranes were applied just prior to abdominal closure in 121 patients who underwent abdominal surgery.

Preoperative serum carcinoembryonic antigen level as a predictive factor of recurrence after curative resection of colorectal cancer.

Background: We evaluated the prognostic value of the preoperative serum carcinoembryonic antigen (CEA) level in patients with colorectal cancer (CRC).

Patients And Methods: The study group comprised 638 patients. The optimal cutoff value for the preoperative serum CEA level was determined.

Procedures of choice for resection of primary and recurrent liver metastases from colorectal cancer.

Although liver resection offers the only realistic chance of cure for patients with liver metastases from colorectal cancer, no consensus exists as to the procedure of choice for managing these tumors. Data from 193 patients who underwent hepatectomy for liver metastases from colorectal cancer and 26 of 193 patients who underwent repeat hepatectomy for recurrent metastases were collected. The suitability of resection was evaluated retrospectively based on known risk factors for recurrence and patterns of recurrence.
