Randomized clinical trial of stapled hemorrhoidectomy vs open with Ligasure for prolapsed piles

Background The aim of the study was to compare the results in 95 patients randomly allocated to undergo either stapled or open hemorrhoidectomy using Ligasure.Methods Ninety-five patients with grade III and IV hemorrhoids were randomly allocated to undergo either stapled (50 patients) or open using Ligasure (45 patients). Stapled hemorrhoidectomy was performed with the use of a circular stapling device. Open hemorrhoidectomy was accomplished according to the Milligan-Morgan technique by using Ligasure. Postoperative pain was assessed by means of a visual analog scale (VAS). Recovery evaluation included return to pain-free defecation and normal activities. A 6-month clinical follow-up and an 18 (12-24) month median telephone follow-up were obtained in all patients.Results Operation time for open hemorrhoidectomy using Ligasure was shorter [median 13 (range 9.2-16.1) min vs 15 (range 8-17) minutes, p < 0.05]. Median range of VAS score in the stapled group were significantly lower [VAS score after 8 h: 3 (2-6) vs 5 (3-8), p < 0.01; VAS score after first defecation: 5 (3-8) vs 7 (3-9), p < 0.001. The stapled hemorrhoidectomy was associated with an increased incidence of intraoperative bleeding in 18 cases (36%) vs four cases (8.8%) of the Ligasure group. There were three cases (6%) from the stapled group with recurrence of the hemorrhoids and none from the open technique.Conclusions Hemorrhoidectomy with a circular stapler device is easy to perform, but one more line of clips must be added to the device to avoid intraoperative bleeding from the cut line. Hemorrhoidectomy performed using Ligasure is more painful postoperatively but is a more radical operation.     

Comparison of Monopolar Electrocoagulation, Bipolar Electrocoagulation, Ultracision, and Ligasure

Purpose Hemostasis is a fundamental principle of surgery. We compared the safety and efficacy of monopolar electrocoagulation (ME), bipolar electrocoagulation (BE), Ligasure (LS), a modern bipolar vessel sealing system, and Ultracision (UC), a system of ultrasound energy based shears. We also studied the healing process after their use. Methods We used each of the above methods to coagulate and divide the short gastric vessels of 16 white male New Zealand rabbits. The animals were killed after 3, 7, 14, or 21 days, and the coagulation sites and the adjacent gastric wall were examined histologically. Results LS and UC achieved complete hemostasis without any complications. Conversely, ME and BE often resulted in failed coagulation and perforation of the neighboring gastric wall from a side thermal injury. Histologically, LS demonstrated the mildest side thermal injury and the fastest healing process. We noted greater thermal injury and inflammatory response after UC than after LS on days 7 and 14; however, ME and BE caused the most severe lesions. Conclusions LS and UC are clearly the safest and most efficient methods of coagulation, whereas ME and BE could cause serious clinical and histological complications. We found histological evidence that UC causes a slightly greater inflammatory response than LS, and the clinical implications of this warrant further investigation.

Meta-analysis of stapled hemorrhoidopexy vs LigaSure hemorrhoidectomy

AIM: To compare outcome of stapled hemorrhoidopexy (SH) vs LigaSure hemorrhoidectomy (LH) by a meta-analysis of available randomized controlled trials (RCTs). METHODS: Databases, including PubMed, EMBASE, the Cochrane Library, and the Science Citation Index updated to December 2012, were searched. The main outcomes measured were operating time, early postoperative pain, postoperative urinary retention and bleeding, wound problems, gas or fecal incontinence, anal stenosis, length of hospital stay, residual skin tags, prolapse, and recurrence. The meta-analysis was performed using the free software Review Manager. Differences observed between the two groups were expressed as the odds ratio (OR) with 95%CI. A fixedeffects model was used to pool data when statistical heterogeneity was not present. If statistical heterogeneity was present (P < 0.05), a random-effects model was used. RESULTS: The initial search identified 10 publica-tions. After screening, five RCTs published as full articles were included in this meta-analysis. Among the five studies, all described a comparison of the patient baseline characteristics and showed that there was no statistically significant difference between the two groups. Although most of the analyzed outcomes were similar between the two operative techniques, the operating time for SH was significantly longer than for LH (P < 0.00001; OR= -6.39, 95%CI: -7.68 -5.10). The incidence of residual skin tags and prolapse was significantly lower in the LH group than in the SH group [2/111 (1.8%) vs 16/105 (15.2%); P = 0.0004; OR= 0.17, 95%CI: 0.06-0.45). The incidence of recurrence after the procedures was significantly lower in the LH group than in the SH group [2/173 (1.2%) vs 13/174 (7.5%); P = 0.003; OR= 0.21, 95%CI: 0.07-0.59]. CONCLUSION: Both SH and LH are probably equally valuable techniques in modern hemorrhoid surgery. However, LigaSure might have slightly favorable immediate postoperative results and technical advantages.
