Comparison of ۳-port with standard ۴-port laparoscopic cholecystectomy: A clinical trial

Introduction: Since the laparoscopic cholecystectomy was introduced first in ۱۹۹۰, the ۴-port laparoscopic cholecystectomy was the gold standard. The ۴-port (lateral) is used to hold gallbladder fundus and observe Calot's triangle. It is discussed that the ۴-port technique is not required in many patients. Therefore, this study aimed to make a comparison between ۳-port and ۴-port laparoscopic cholecystectomy methods in the treatment of gallstone disease. Methods: A double-blind clinical trial was performed on patients admitted to Imam Reza Hospital, Birjand, Iran. The patients with gallstone disease (n=۶۰) were randomly assigned into the case (۳-port) and control (۴-port) groups using balanced block randomization and underwent ۳- or ۴-port laparoscopic cholecystectomy. Postoperative pain was measured by a visual analog scale four h after surgery. The amount of pain-killer, duration of surgery, as well as length of stay and scars were measured in this study. Data were analyzed statistically in SPSS software (version ۱۸) through the Chi-square test and t-test. A p-value less than ۰.۰۵ was considered statistically significant. Results: The groups were compared in terms of demographic characteristics. There were ۲۴ females (۸۰%) and ۶ males (۲۰%) in the control group and ۲۵ females (۸۳.۴%) and ۵ males (۱۶.۷%) in the case group (P=۰.۷۳۹). Moreover, the mean ages of the control and case groups were ۵۹.۸۲۳±۷.۸ and ۶۱.۱۰±۴.۷, respectively, and there was no significant difference between the groups in this regard (P=۰.۳۴۸). Furthermore, length of operation (P=۰.۰۰۱) and analgesic consumption (P=۰.۰۰۱) in the ۳-port laparoscopic cholecystectomy group were lower than those in the ۴-port group; however, the hospital stay (P=۰.۸۹۶) was the same in both groups. Conclusions: The ۳-port laparoscopic cholecystectomy is a safe, reliable, and cost-effective method in patients who underwent laparoscopic cholecystectomy.
