ObjectiveTo investigate the value of ultrasound knife in modified radical mastectomy for remaining pectoral nerve and intercostobrachial nerve. MethodsOne hundred and sixty patients with breast cancer were divided into ultrasound knife group and electroscalpe group and then performed modified radical mastectomy with pectoral nerve and intercostobrachial nerve remainning. the pectoralis major thickness and paresthesia of skin of inner upper arm and axillary fossa were detected on the different time after operation. Results①The age, body mass index, and mean opera-tion time had no significant differences between these two groups (P > 0.05).②On 6 months after operation, the thickness of bilateral pectoralis major was not significantly different in the ultrasound knife group (P > 0.05), which of injuried pectoralis major was significantly thinner than that of uninjuried pectoralis major in the electroscalpe group (P < 0.05).③The rates of paresthesia of skin on postoperative 3 months and 6 months in the ultrasound knife group were signifi-cantly lower than those in the electroscalpe group (P < 0.05). ConclusionCompared with monopolar electro diathermy, the use of ultrasonic harmonic scalpel in modified radical mastectomy could better protect pectoral nerve and intercosto-brachial nerve, and thus decrease nerve parafunctional rate.
Objective To compare the disadvantages and advantages of open thyroid surgery when using the harmonic scalpel (HS) vs conventional hemostasis (CH). Methods One hundred and fifty-one patients and 70 patients underwent thyroid surgery with HS or CH respectively. The tumor diameter, incisional length, the total operative time, thyroidectomy time, intraoperative bleeding volume, postoperative drainage volume and surgical complications were compared. The incisional length and the surgical complications in and after learning curve with harmonic scalpel were compared. Results There was no significant difference between the HS and CH group at baseline. Incisional length, total operative time, thyroidectomy time, intraoperative bleeding volume and postoperative drainage volume in HS group were significantly lower than those of CH group (P＜0.001); the surgical complications showed no significant difference between the HS and CH group (Pgt;0.05); the incisional length after learning curve was shorter than that in learning curve in HS group (P＜0.05); the surgical complications after learning curve were significantly lower than that in learning curve in HS group (P＜0.001). Conclusion HS provides significant advantages over conventional hemostasis in open thyroid surgery. However, it can’t be used in a blindly exclusive way but be combined with conventional knot tying appropriately.
ObjectivesTo systematically review the safety of harmonic scalpel and conventional resection in superficial parotidectomy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) or cohort studies of harmonic scalpel and conventional resection in superficial parotidectomy from the inception of the database to December, 2018. Two reviewers independently screened literatures, extracted data and assessed risk of bias of the included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 studies involving 671 post-cesarean section patients (361 patients in harmonic scalpel group and 310 patients in conventional resection group) were included. The results of meta-analysis showed that: compared with conventional resection, harmonic scalpel had shorter operative time (MD=−23.82, 95%CI −31.20 to −16.44, P<0.000 01), less postoperative drain output (MD=−26.25, 95%CI −38.95 to −13.55, P<0.000 1), less intraoperative blood loss (MD=−23.78, 95%CI −28.64 to −18.91, P<0.000 01), shorter duration of hospital stay (MD=−1.19, 95%CI −2.14 to −0.23, P=0.02), and lower temporary facial nerve palsy rate (OR=0.27, 95%CI 0.14 to 0.50, P<0.000 1). However, there was no significant difference in the incidence of parotid gland leakage between two groups (OR=0.42, 95%CI 0.16 to 1.06, P=0.07).ConclusionsThe current evidence demonstrates that, compared to conventional resection, harmonic scalpel resection is safer. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective To discuss the differences of the effects on open colorectal cancer operation between using ultracision harmonic scalpel (UHS) and monopolar electrosurgery. Methods Fifty-nine patients from April to December in 2007, suffering colorectal cancer in the same treatment group, underwent open radical operation, 29 by GEN300 UHS (UHS group) and 30 by monopolar electrosurgery as control group. There was no significant difference between two groups among the factors of age, gender, tumor location, Dukes staging, gross morphology and degree of histological differentiation (Pgt;0.05). Results Shorter incision was applied in UHS group than in the control group. The mean operation time of UHS group and control group were 126 and 119 min, respectively (Pgt;0.05). The mean operative blood loss was 50 (20-140) ml in UHS group and 90 (40-200) ml in control group (Pgt;0.05). There were no significant differences among factors of bowel function recovery, mean hospitalization and incidence of complications between two groups (Pgt;0.05). The mean time for postoperative drainage fluid changing from bloody to serous was 8 (2-20) h in UHS group, however, 48 (16-80) h in control group (Plt;0.05). Conclusion In open colorectal cancer operation, benefits of using UHS are shorter incision and minimally invasiveness.
Objective To investigate the effect and surgical skill of ultracision harmonic scalpel in curative gastrectomy for patients with gastric carcinoma. Methods From January 2007 to May 2008, the data of 152 patients who were treated by curative gastrectomy with ultracision harmonic scalpel were analyzed retrospectively. Results The mean operative time was (189.5±24.2) min. Compared with the conventional operation, the number of harvested lymph nodes (mean: 30.4±11.6) in patients treated with ultracision harmonic scalpel was increased. The application of ultracision harmonic scalpel could shorten the operation time, decrease the intraoperative blood loss and make the operation field clear. There were no postoperative complications, such as anastomotic leakage, lymphatic leakage and massive hemorrhage. And there was no death in this series. Conclusion The usage of ultracision harmonic scalpel which could improve the curative degree of lymphadenectomy is safe in curative gastrectomy for patients with gastric carcinoma.
Objective To compare the efficacy and complication between harmonic scalpel and traditional electric knife in open thyroidectomy. Methods A total of 160 thyroid disease patients who underwent open thyroidectomy in The Fifth Affiliated Hospital of Southern Medical University from February 2016 to January 2017, were collected and divided into harmonic scalpel group and traditional electric knife group randomly, each group enrolled 80 patients. The efficacy of thyroidectomy, postoperative pain, and complication between the 2 groups were compared and analyzed. Results Compared with the traditional electric knife group, the operation time, intraoperative blood loss, postoperative drainage volume, postoperative drainage time, length of incision, and hospital stay were all significantly lower in the harmonic scalpel group (P<0.05). The incidences hoarseness, wound bleeding, hypoparathyroidism, and total complication in the harmonic scalpel group were all lower than those of the traditional electric knife group (P<0.05). The pain scores after operation in the harmonic scalpel group were significant lower than corresponding pain scores of the traditional electric knife group (P<0.05). Conclusion The harmonic scalpel could effectively improve the efficacy of open thyroidectomy, reduce the pain degree and the incidence of complication in thyroid disease patients.
ObjectiveTo evaluate the feasibility of clipless laparoscopic cholecystectomy (LC) to patients with calculous cholecystitis in acute inflammation stage. Methods The clinical data of 169 patients with calculous cholecystitis in acute inflammation stage who underwent clipless LC from December 2008 to July 2010 were analyzed. ResultsAll patients were successfully operated by LC except one case who suffered from gallbladder perforation and a conversion to open surgery was performed. The operation time ranged from 25-70 min (mean 38 min). The blood loss ranged from 10-200 ml (mean 22 ml). Peritoneal drainage was done in 38 patients, and the drainage time ranged from 1-6 d (mean 1.8 d). The time to out-of-bed activity was at 2 h after operation and the hospitalization time was 3-7 d (mean 3.5 d). There was no complication such as bile duct injury, hemorrhage, billiary leakage, and intra-abdominal infection. ConclusionWith improvement of operator’s experiences and skills, the clipless LC becomes feasible and safe for patients with calculous cholecystitis in acute inflammation stage.
Objective To assess the feasibility and adequacy of Harmonic Scalpel in a totally laparoscopic total mesorectal excision (TME) and low,ultralow,colo-anal anastomoses for rectal cancer. Methods Excision of the mesorectum and low，ultralow site anastomoses were performed laparoscopically on 30 patients with low rectal cancer based on the concept of TME. Results All 30 TME were successfully completed by laparoscopic approach, and no one was converted to open procedures. A cholecystectomy and/or an ovariotomy were meanwhile performed laparoscopically for 3 patients with rectal cancer,and 1 patient with chronic cholesyctitis, gallstone,ovarian cyst and torsion of the ovary. The operation time was 155 min (115-320 min). Operative blood loss was 20 ml (5-80 ml).The time of bowel function returned and the time to resume postoperative diet was 1-2 days after the operation. Fourteen patients had postoperative analgesic requirement. Average hospital stay was 8 days (5-14 days) and there were no intraoperative and postoperative complications in all 30 patients.Conclusion Laparoscopic excision of the mesorectum and low,ultralow,coloanal anastomoses with Harmonic Scalpel for low rectal cancer is a perspective minimally invasive technique, which is feasible, safe, effective and has dramatic high rates of sphincter preservation with decreased postoperative pain, rapid recovery.
