Abstract

In this prospective randomized study, our aim is to compare the short- and long-term results of harmonic scalpel hemorrhoidectomy (HSH) and stapler hemorrhoidopexy (SH) methods in the surgical treatment of Grade III and Grade IV hemorrhoidal disease. Ninety-nine consecutive patients diagnosed with Grade III or Grade IV internal hemorrhoidal disease were included in the study. Patients were randomized to HSH (n = 48) or SH (n = 51) treatments. Data on patient demographic and clinical characteristics, operative details, postoperative pain score on a visual analog scale, additional analgesic requirement, postoperative short- and long-term complications, and recurrence of hemorrhoidal disease were also recorded. Patients were regularly followed for a total period of 24 (6–36) months. The patient demographic and clinical characteristics were similar in the two groups. The operative time was significantly shorter in the HSH group compared with the SH group. Overall pain scores were not significantly different between the groups, although severe pain was significantly more common in the HSH group. Recurrence was significantly lower in the HSH group compared with the SH group. HSH and SH are both safe and effective methods for surgical treatment of Grade III and Grade IV hemorrhoidal disease. In our study, the HSH method was determined to be safer, easier, and faster to perform, and associated with fewer long-term recurrences than the SH method.

Abstract

To compare the efficacy and safety of both mechanical methods (clips) and electrosurgical instruments, harmonic scalpel (HS) and LigaSure (LS), for securing the cystic duct during laparoscopic cholecystectomy (LC). During the study period from October 2010 to October 2012, 458 patients with gallbladder stones underwent LC. A total of 38 patients were excluded from the study for different reasons. The gallbladder was excised laparoscopically through the traditional method. The gallbladder specimens of the patients were divided into three equal groups randomly, and the distal part of the cystic duct was sealed ex vivo using ligaclips (Group A), HS (Group B), and LS (Group C). The gallbladders were then connected to a pneumatic tourniquet device and we very gradually increased the pressure with air. The bursting pressure of the cystic duct (CDBP) was measured and differences between the three groups were calculated. The mean CDBP was 329.7 ± 38.8 mmHg in the ligaclip group, 358.0 ± 33.1 mmHg in the HS group, and 219.7 ± 41.2 mmHg in the LS group. A comparison of the mean CDBP between the groups indicated the superiority of HS over ligaclip and LS. CDBP was significantly higher in the ligaclips group compared with the LS group (p <0.001). HS and ligaclips were found to be safe sealers as their mean CDBP was found to be higher (>195 mmHg) than the maximum common bile duct pressure, whereas for LS the CDBP range was 150–297 mmHg, indicating that it is not safe for sealing. HS is a safe alternative to clips. In fact, it was even safer than clips. By contrast, LS is not safe for cystic duct sealing.
