Objective To explore the effect of minimally invasive and mini-incision surgery (MIS) in total hip arthroplasty (THA) on late osteonecrosis of femoral head (ONFH). Methods From March 2003, Eighteen patients (22 hips) with ONFH underwent MIS in THA. Their ages ranged from 24to 57 years, including 13 males and 5 females. The mean body mass index ranged from 17.1 to 30.1(24.6 on average). The Harris hip score was 46 points before operation. Modified posterior-lateral approach was adopted, and the MIS THA was performed by cementless prosthesis. As a comparison, 18 patients (22 hips) were performed by conventional THA at the same period. The data, including bleeding volume during operation, incision length, operative time, and postoperative function recovery, were compared. Results Follow-ups were done for 6 to 20 months (11 months on average). Dislocation occurred in one patient that underwent conventional THA 2 days after operation. No complication occurred in MIS THA group. The incision lengths ranged from 8.7 to 10.5 cm (9.3 cm on average) in MIS THA group, being statistically different (Plt;0.01). There was no significant difference in Harris scoring of the function between the two groups both before the operation and after the operation (Pgt;0.05). The operative time was almost the same, but the bleeding volume in MIS THA group was less (Plt;0.05). The function recovery was faster in MIS THA group.Conclusion The MIS THA is an alternative to the treatment of late ONFH. The advantages of MIS THA are fewer trauma, less bleeding volume, and faster recovery. The MIS THA should be performed by surgeons with rich experiences in THA and hospitals with necessary instruments.
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 explore an effective micro-traumatechnic with small incision for hallux valgus. Methods From August 2002 to June 2004, 136 cases (263 feet) with hallux valgus were treated with micro-trauma technic with small incision and postoperative external elastic fixation. Of all the cases, 7 were males and 129 werefemales. Their ages ranged from 19 to 84 years. According to Coughlin classification, there were 24 gentle cases, 63 medium cases, and 49 severe cases. All the feet were with some degree of pain and flatfoot. Symptom, sign and theresults of X-ray were evaluated. Results Wound healed at stage Ⅰ.All cases were followed up for 8 to 26 months, 19 months on average. Hallux valgus of the 263 feet were completely healed, feet pain disappeared, and no nonunion or osteonecrosis was observed. Xray examination indicated that 105 feet’s hallux valgus angle was less than 12°, inter metatarsal angle less than 9°, and remedy subluxation of the tibial sesamoid less than 50%. Evaluation on the result indicated that there were 84 cases of excellent result, 48 cases of good result, 3 cases of fair result, and 1 case of poor result. The rate of excellent and good was 97%. Conclusion With less injury, less pain, complete restoration, and fewer possibility of relapse, microtrauma technic with small incision is effective in treating hallux valgus.
目的探讨小切口胆总管末端结石的治疗。方法对110例胆总管末端结石患者采用小切口术中胆道镜、气囊导管等治疗的临床资料进行回顾性总结。结果术中采用胆道镜、气囊导管等清除末端结石86例（78.2%）。术后用胆道镜取出结石10例（9.1%），胆道镜联合内镜乳头括约肌切开技术清除结石14例（12.7%）。术中18例(16.4%）并发胆总管末端医源性损伤，其中1例术后并发消化道大出血死亡，其余病例经2~20年随访无远期并发症。结论胆总管末端结石采用小切口术中胆道镜、气囊导管等相结合能清除多数结石，难以取出的末端结石于术后经内镜处理为妥。
目的 总结840例小切口胆囊切除术的经验体会。方法 我院应用新器械行小切口胆囊切除术840例，男302例，女538例，年龄16～64岁； 胆囊结石832例，胆囊息肉8例。其手术指征与大切口胆囊切除术相同。术中应用小切口自动伸开架、深部送结器、小切口带灯拉钩、缝合胆囊肝床之外科扣锁钳、肝脏直角灯钩以及为防止在小切口内手术时遗失纱布而特制的气囊纱布； 同时，确保手术能在小切口内完成，术前进行了周密检查以排除肝、胆、胃之肿瘤，并于术前行动态胆囊底B超定位检查，以确定小切口之位置和了解手术难易。结果 840例中行择期手术737例，急诊手术103例； 手术历时平均30分钟； 住院时间3～4天。术后全部患者均获随访，其满意度为98.5%(827/840)。因照明障碍误伤右肝管1例，因胆囊颈结石嵌顿误伤胆总管1例。结论 应用小切口及自制手术器械行胆囊切除术，避免了LC及传统开腹术的一些弊端，效果确切，便于患者接受。
