The use of 3.5-mm trocars is feasible in LC, and it both reduces incisional pain and improves the cosmetic result.

ERCP, even for diagnostic purposes, may be associated with very serious and even fatal complications. The use of the precut procedure for access should still be considered dangerous. Other means of investigating the bile ducts should be developed. If endoscopic ultrasonography and magnetic resonance cholangiography prove to have the same diagnostic value as ERCP, which must be considered the gold standard for visualizing the ducts today, they might replace ERCP as the primary investigation in patients with an intermediate or low risk of bile duct stones; this would reduce the numbers of patients exposed to the risks of ERCP.

Micro-LC in combination with a prophylactic multimodal analgesic regimen reduced postoperative pain for the first 3 h postoperatively. However, the micro-LC led to an unacceptable rate of conversion to LC (38%). The micro-LC instruments therefore need further technical development before this surgical technique can be used on a routine basis for laparoscopic cholecystectomy.
