Objective To study the role of ultracision harmonic scalpel and skin flap in axillary fossa external fixation in operation of breast cancer. Methods One hundred and sixty-six patients with breast cancer were included in this study between May 2009 and November 2009. Combined group (n=51) applied ultracision harmonic scalpel combined with skin flap external fixation. External fixation group （n=52） used the skill of skin flap external fixation. Routine group included 63 patients. Operative time, accidental injury during operation， volume of bleed and drainage, time of drainage, detection amount of lymph node, and complications such like subcutaneous fluidity were observed and recorded. Results The operative time and detection amount of lymph node were not different among three groups （Pgt;0.05）. The volume of bleed in combined group was less than that in other groups （Plt;0.05）. The volume of drainage and the time of drainage were decreased or shorten by turns from routine group, external fixation group to combined group （Plt;0.05）. The incidence rate of subcutaneous fluidity in combined group was lower than that in routine group （Plt;0.05）. Conclusions Using ultracision harmonic scalpel in operation of breast cancer can remarkably reduce the volume of bleed and drain postoperatively. Ultracision harmonic scalpel combined with skin flap external fixation is safety and can reduce the incidence rate of subcutaneous fluidity, thus can be applied widely in breast cancer operation.
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.
Objective To study the application of ultracision harmonic scalpel in laparoscopic radical gastrectomy. Methods Ten patients with gastric cancer were given laparoscopic-assisted radical gastrectomy by using ultracision harmonic scalpel. Results All operations were successfully performed with ultracision harmonic scalpel, and none of which converted into open surgery. The operation time was 300-492 min, mean (385±64) min. The blood loss was 100-500 ml, mean (401±70) ml. The number of harvested lymph nodes was 21-43, mean 31±6. The time for gastrointestinal function recovery was 3-6 d, mean (4.2±1.0) d. The time of patients’ taking out-of-bed activity was 3-７ d, mean (4.5±1.3) d. The time of taking liquid food was 4-６ d, mean (5.0±0.9) d. No case had relapse or metastasis after 4-20 months (mean 12.6 months) of follow-up. Conclusions Laparoscopic radical gastrectomy by using ultracision harmonic scalpel is safe and feasible. Ultracision harmonic scalpel has the advantage of minimal invasion, less bleeding and shorter operation time, which is a very important equipment and useful for laparoscopic gastrointestinal surgery.
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.
ObjectiveTo discuss the influence of ultracision versus electrotome on the immune function and stress reaction in patients after rectal cancer Miles operation. MethodA retrospective analysis was performed on 82 rectal cancer patients who received Miles operation between February 2007 and August 2012. Among them, 45 accepted ultracision, and 37 received electrotome operation. We compared the two groups in terms of abdominal and perineum surgery time, blood loss volume, drainage volume within 72 hours after operation, and analyzed the CD3+, CD4+, CD8+, CD4+/CD8+ ratio by flow cytometry before and after operation. In addition, we tested the white blood cell count, percentage of granulocyte, C-reaction protein (CRP), and interleukin (IL)-6 three days after operation. ResultsThere was no obvious difference in CD3+, CD4+, CD8+, CD4+/CD8+ ratio between the two groups. However, the incidence of blood loss volume, abdominal operation time, perineum operation time, drainage volume within 72 hours after operation, white blood cell count, percentage of granulocyte, CRP, IL-6 in the ultracision group was dramatically lower compared with the electrotome group (P<0.05). ConclusionsThere is no significant difference in the influence on the immune function between the two kinds of operation methods, but ultracision can achieve faster recovery and smaller stress reaction after operation. It is worthy of clinical popularization.
