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.
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.
目的 探讨超声刀在肝包虫全囊切除术中的应用。方法 回顾性分析11例接受超声刀肝包虫手术患者的治疗及效果。结果 9例患者行全囊切除，其中1例因包虫与胆管相通，在进行全囊切除后，缝扎胆管，同时行T管引流； 1例因包虫与膈肌粘连无法分离，给予外囊大部切除术； 1例因包虫与膈肌粘连无法分离，给予外囊大部切除术； 1例10岁患者为肝顶部包虫，手术行内囊切除及外囊大部切除后，出现残腔感染，经穿刺引流后，证实为漏胆，经引流后痊愈出院。9例全囊切除患者术中均未输血，术后未出现并发症。结论 在肝包虫全囊切除术中应用超声刀是安全、有效的。
目的 探讨超声刀（ultrasonic harmonic scalpel，UHS）在消化道恶性肿瘤开腹手术中的应用价值。方法 回顾性分析2009年10月至2011年10月期间广西壮族自治区人民医院普通外科-小儿外科收治并由同一手术者进行消化道恶性肿瘤开腹手术的186例患者的临床资料，根据接受手术的种类（UHS开腹手术或传统电刀开腹手术）将其分为UHS组（86例）和传统电刀组（100例），比较2组患者的手术切口长度、手术时间、术中出血量、术后3d引流量、术后住院时间以及住院总费用。结果 UHS组手术切口长度、手术时间、术中出血量以及术后住院时间均短于（少于）传统电刀组（P＜0.05）；术后3d引流量和住院总费用2组间比较差异均无统计学意义（P＞0.05）。结论 将UHS应用于消化道恶性肿瘤开腹手术可获得较好的效果，能提高手术操作的效率，具有很好的应用前景。
【Abstract】ObjectiveTo study the application of ultrasonically activated scalpel in laparoscopic intestinal adhesion release.MethodsIntestinal adhesion release with ultrasonically activated scalpel under laparoscope was performed in 29 patients suffered from intestinal adhesive obstruction after gynecological operation. ResultsAll operations were successfully performed, and none of them converted into open surgery. Intestinal disruption occurred durring operation in 2 patients with extensive intestinal denseadhesion which were mended successfully under laparoscope. The operative duration was 30-150 min (mean 45 min). Postoperative complications such as bowel leakage, bleeding, abdominal infection were not experienced. Postoperative hospital stay was 3-7 days (mean 4 days). No case had relapse symptom such as abdominal distention or pain after 1-24 months of followup. ConclusionCompared with electric scalpel, ultrasonically activated scalpel can improve the operative safety, lessen tissue damage, shorten operative time, and reduce the chance of relapse in laparoscopic operation in gynecology.
ObjectiveTo summarize the use of harmonic scalpel to harvest bilateral internal mammary artery in coronary artery bypass grafting (CABG). MethodsThe clinical data of 54 patients of bilateral skeletonized internal mammary artery harvesting for CABG in our hospital from January 2016 to May 2020 were analyzed retrospectively. There were 51 males and 3 females with a mean age of 62.37±9.56 years. ResultsAll patients went through the procedure unevently and discharged from hospital. The number of grafts was 4.07±0.85 per patient, the operation time was 267.21±47.00 min, mechanical ventilation time was 342.43±132.17 min and hospital stay was 12.21±4.43 d. ConclusionIt is safe and effective to use harmonic scalpel to harvest skeletonized bilateral internal mammary artery in CABG.
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 evaluate the clinical outcomes of harmonic scalpel in subxiphoid and subcostal arch approach for resection of anterior mediastinal lesion. Methods We retrospectively analyzed the clinical data of 217 patients with anterior mediastinal lesion at the Department of Thoracic Surgery of Tangdu Hospital of the Fourth Military Medical University from June 2015 to June 2017, among whom 162 underwent thoracoscopic surgery via subxiphoid and subcostal arch approach with harmonic scalpel (a harmonic scalpel group, 95 males and 67 females at an average age of 46.2±18.7 years ranging from 22 to 72 years) and 55 with Ligasure (a Ligasure group, 29 males and 26 females at an average age of 47.7±12.9 years ranging from 31 to 68 years). Operation time, intraoperative blood loss, intraoperative conversion rate, postoperative hospital stay, patients satisfaction score, patients pain score and postoperative complications were compared between both groups. Results All operations were accomplished successfully, and there was no death or conversion to thoracotomy. There was a statistical difference in operation time (58.6±34.8 min vs. 72.8±32.6 min, P=0.01), and intraoperative blood loss (36.2±18.7 ml vs. 41.9±12.9 ml, P=0.04). There was no statistical difference between the two groups in length of hospital stay (4.2±2.6 d vs. 4.5±1.9 d, P=0.36), pain score at postoperative day 1, 3 and 30 (8.3±0.9 vs. 8.5±0.6, P=0.13; 6.4±1.5 vs. 6.9±1.1, P=0.19; 1.3±0.7 vs. 1.4±0.9, P=0.40), patients’ satisfaction score (8.6±1.2 vs. 8.4±1.7, P=0.34), or incidence of postoperative complications (5.6% vs. 9.1%, P=0.35). Conclusion Harmonic scalpel plays an important role in resection of anterior mediastinal lesion via subxiphoid and subcostal arch approach. All tissues are separated and blood vessels are dissected only by the harmonic scalpel, so it is very important for us to handle the harmonic scalpel skillfully.
