Objective To evaluate the effect of recombinant human growth hormone(rhGH) on growth of human colonic cancer cells (COLO-320) in vitro. Methods Human COLO-320 cells in logarithm growing period were cultured for 24 h,48 h or 72 h with variant concentrations of rhGH,camptothecine (CPT) or rhGH combined CPT in calf serum(serum group) or calf serum-free (serum-free group). Light density of cells were determined by MTT method, so that cellular inhibition rate were calculated.Results No influence on cell growth or inhibition rate was observed from cultures with variant concentrations and different acting times of rhGH (P＞0.05). Inhibition rate of single CPT or CPT combined rhGH were much more increased than single rhGH used (P＜0.01) with no statistical significance (P＞0.05).Conclusion The results show that rhGH has neither direct COLO-320 cells stimulation nor any evidence of COLO-320 cells inhibition, and has no influence of CPT on COLO-320 cells inhibition in vitro.
Objective To investigate the effect of laparoscopy combined with choledochoscopy on common bile duct (CBD) stones with primary suture of the CBD. Methods Totally 523 patients of gallbladder stone companied with CBD stones or choledochectasia (diameter ≥0.8 cm) from September 1998 to December 2008 were retrospectively analyzed. Results The primary suture of the CBD incision was successfully performed in 487 patients. The CBD stones were completely removed during the operation in 400 patients. Nothing was found in 87 cases. In 10 cases conversion to open surgery were performed and in 26 cases the T tube drainage was put into the CBD in choledocholithotomy. Average operative time was 90 min and average bleeding volume was 50 ml. All patients took food at 24 h, returned general activity on 2-3 d and discharged on 5 d after operation. Postoperative biliary leakage occurred in 29 cases with drainage average volume of 35 ml/d and continued 1-6 d, which were cured by non-operation therapy. Conclusions The primary suture of the CBD during the laparosocopy combined with choledochosopy in choledocholithotomy is a safe and effective operation with less invasion, less pain and quicker recovery. CBD incision suture without T tube drainage can be done when CBD stones are cleared completely and no stenosis is found in extrahepatic bile duct.
ObjectiveTo further explore and discuss the value of laparoscopic appendectomy. MethodsThe clinical data of 200 patients underwent appendectomy in this hospital from April 2009 to December 2010 were collected. The operation time, postoperative hospital stay, cost of hospitalization, postoperative anal exhaust time, postoperative pain score, and surgical complications were compared between laparoscopic appendectomy and open appendectomy. ResultsThere were 8 cases conversion to the open approach in this series. The cost of laparoscopic appendectomy was higher than that of open appendectomy (Plt;0.05); the cases of chronic appendicitis, acute simple appendicitis, acute suppurative appendicitis within 36 h of onset treated by laparoscopic appendectomy had shorter operation time, shorter postoperative hospital stay, earlier postoperative anal exhaust time, and slighter postoperative pain than those treated by open appendectomy (Plt;0.05); the differences in postoperative hospital stay, postoperative anal exhaust time, postoperative pain of acute suppurative appendicitis more than 36 h of onset and acute gangrenous appendicitis treated by two types of surgery had no statistical significances (Pgt;0.05); the operation time of acute gangrenous appendicitis operated by laparoscopic surgery was longer than that by open appendectomy (Plt;0.05); incision infection rate of laparoscopic appendectomy was lower than that of open appendectomy (Plt;0.05). ConclusionsFor chronic appendicitis, acute simple appendicitis, and acute suppurative appendicitis within 36 h of onset, the outcome and advantages of laparoscopic appendectomy are outstanding, the value of application is clear; and for acute suppurative appendicitis more than 36 h of onset and acute gangrenous appendicitis, laparoscopic appendectomy is difficult and with high rate of conversion, no obvious advantages in recovery after surgery but an increase of medical costs, and the application value is not great.
目的 探讨成人先天性胆总管囊肿的诊治方法和手术技巧。方法 对2001年5月至2011年5月期间我院手术治疗的成人先天性胆总管囊肿38例的临床资料进行回顾性分析。结果 全部病例均行B超和磁共振（MRCP）检查确诊，均行手术治疗。其中7例行急诊囊肿外引流术。行择期手术者中24例行囊肿切除、胆肠吻合术，其中3例合并肝叶切除术； 行内引流术4例； 仅行胆囊切除术3例。囊肿剥除采用点状钳夹、电凝及推剥囊肿黏膜外纤维血管束的办法，不出血，无副损伤。无手术死亡病例，术后恢复顺利。38例患者中术后获随访28例（73.68％），失访10例； 随访时间 3～120个月，平均74个月。24例行囊肿切除者症状消失20例，偶感上腹痛、抗炎治疗后症状可缓解1例，3例失访；11例行内或外引流术者术后近期均有不同程度的胆管炎症状，其中6例于术后2～10 年再手术，另5例失放，6例再手术者中2例术中发现癌变，分别于再手术后2个月和10个月死亡，余4例临床症状消失；3例仅行胆囊切除术者，2例失访，1例仍有反复发作的畏寒、发热及右上腹痛。结论 B超和MRCP检查有助于明确诊断； 囊肿全切除、肝管空肠Roux-en-Y 吻合术应作为胆总管囊肿的首选术式，囊肿外引流术仅在合并严重感染、全身情况差的患者采用； 手术技巧的改进可为手术提供安全保障。
