Minilaparotomy cholecystectomy presents exposition difficulties, and laparoscopy requires expensive equipment and additional training. Laparotomy is more painful, causes trauma to the abdominal wall, and requires a longer convalescence; it is also less aesthetic. We present a new technique for minilaparotomy cholecystectomy, transcylindrical cholecystectomy (TC), based on the introduction of a 3.8- or 5.0-cm diameter cylinder (10.0 cm long). The cylinder serves the purpose of separating and isolating the hepatocystic triangle from the surrounding structures, thereby providing a stable surgical field and adequate vision of the hepatocystic triangle so the technique can be performed safely. Patients who have been diagnosed with symptomatic cholelithiasis, who are convalescent from biliary pancreatitis, or who have acute cholecystitis have been treated consecutively by TC. We have carried out the procedure on 116 occasions, 94 using the 3.8-cm cylinder and 28 with the 5.0-cm cylinder; both cylinders were used in 6 cases. The indications for using the 5.0-cm cylinder were mainly cholecystitis, pancreatitis, choledocholithiasis, and difficulty with the 3.8-cm cylinder. The result is a 4.5- or 7.0-cm incision. We had difficulty recognizing the anatomy in 11 dissections so we had to enlarge the incision. We have not had accidents related to placement of the cylinder, hemorrhage, or bile duct injuries. The median operating time was 43 minutes, and the mean postoperative stay was 1.8 days. Postoperative FVC and FEV, reductions were 21.7% and 27.4%, respectively. The technique has proved fast, safe, and practicable using conventional material. The cost of TC is $701 (US).
