Laparoscopic surgery induced interleukin-6 levels in serum and gut mucosa: implications of peritoneum integrity and gas factors.

Background: The peritoneum serves as an integral part of host immunity, and the homeostasis of intraperitoneal environment is held to be beneficial for patient recovery after abdominal surgery. How minimal invasive access to the abdomen by laparoscopy and incisions would alter the intraperitoneal immune response is not fully defined. This study examined the levels of IL-6 in serum and gut mucosa following laparoscopic surgery with reference to the peritoneum integrity and gas factors.

Laparoscopic colorectal resection: a safe option for elderly patients.

Background: Open colorectal surgery in the elderly has been associated with higher morbidity and mortality rates. The favorable short-term outcomes of laparosocopic colorectal resection might reduce the morbidity in elderly patients. This study compares results of elderly patients (aged 70 and above) who underwent laparoscopic colorectal resection with those having open surgery.
