Laparoscopic instrumentation: Linear cutters, clip appliers, and staplers.

Some of the most common forms of instrumentation and technology used laparoscopically include linear cutters, clip appliers, and staplers. The clip applier was the instrument that finally allowed the surgeon to be able to perform laparoscopic cholecystectomies. Staplers were developed quickly thereafter for tacking tissue together or for applying mesh for hernia repairs. Linear cutters became much more useful when the laparoscopic procedures became more advanced, and their application continues to expand. This report reviews the technology regarding these instruments and discusses clip appliers, linear cutter-staplers, and hernia staplers, which are currently available on the market. However, it should be noted that there remains a lack of peer-reviewed literature regarding the efficiency, efficacy, and cost of these instruments compared with that of laparoscopic suturing and knot tying.

Diagnostic and therapeutic choledochoscopy.

Laparoscopic cholecystectomy and common bile duct exploration are common surgical procedures for the general surgeon. To successfully remove common bile duct stones, choledochoscopy is an important technique for efficient and effective management. The choledochoscope can be introduced intraoperatively through the cystic duct or directly into the common bile duct and it also can be inserted transhepatically through a T-tube tract and per orally using a therapeutic duodenoscope. All of these methods allow for many options for the surgeon to consider, and one must be familiar with each of these techniques to maximize care. Successful stone extraction with the choledochoscope can be achieved in 75% to 95% of the cases with a morbidity less than 5%. Using this technique, the surgeon can improve the cost benefit of bile duct exploration.
