Patients undergoing elective colorectal resection can be managed without postoperative NG catheters, starting oral feeding on the first postoperative day. Albeit, no reduction in postoperative hospital stay or patients' well being could be detected, abolition of postoperative NG intubation with early oral feeding was a safe approach, with only 20% of patients requiring NG decompression because of repeated episodes of vomiting.

Our results support the clinical validity of preemptive analgesia, but the timing of intraperitoneal administration of local anesthetic is very important. Only application before creation of the pneumoperitoneum may preempt every neuronal central sensitization.

Preoperative dexamethasone reduces postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy, with no side-effects, and may be recommended for routine use.

No ideal localization technique is available; thus, the choice still depends on surgeon's preference and local availability of both specialists and instruments.
