ABSTRACT
Objective To approach the surgical timing for the conjoined twins, location of the separation line for the joined liver, and the separation method.Methods The common bile ducts of the conjoined twins were considered as two vertical lines, and a vertical line running parallel to the two lines was set as the separation line for the joined liver.Local blood flow blocking method was then used to separate the joined liver.Results Among all the three cases of the conjoined twins, one case was with sternoxiphopagus and the other two with thoracoabdominalpagus.All the three cases of con-joined twins shared the common livers, but each case had respectively separated gallbladders and bile ducts.They underwent the surgical separation at the age of 28 d and 96 d and 89 d successfully.Their liver sections bled rarely by blocking the local blood flow.The liver function recovered successfully af-ter the operation.All the 6 sick children recovered and were discharged from our hospital.Conclusion Porvided the conjoined twins shared the joined liver with respectively separated common bile ducts, in most cases, the injuries of the important liver vascular as well as bile ducts could be avoided when the separation line for the joined liver was selected with the common bile ducts of the conjoined twins as the longitudinal coordinate.The local blood flow blocking method only blocked the local blood flow, in-terfering to the liver blood flow in the non-operating areas rarely, which was instrumental in the recovery of the liver function and increase of the survival rate of the conjoined twins after the operation.
ABSTRACT
Objective To evaluate the safety and efficacy of transumbilical single port laparoscopic cholecystectomy. Methods The clinical data of 16 patients who received transumbilical single port laparoscopic cholecystectomy at Xinqiao Hospital from January 2008 to May 2010 were retrospectively analysed. An incision with a length of 1.5 cm was made adjacent to the umbilicus, and then two 5 mm trocars and one 10 mm trocar were installed. After the establishment of pneumoperitoneum, a laparoscopic camera was placed via the 10 mm trocar,and laparoscopic instruments and a 5 mm ultrasonic scalpel were placed via the two 5 mm trocars, respectively.Cholecystectomy was performed in the same manner as for the conventional laparoscopic procedure. Results All the operations were successfully carried out. The operation time was 50-150 minutes. No drainage tube was inserted,and no complications such as bleeding or bile leakage were observed after the operation. Patients recovered well,and no scarring was observed around the umbilicus. Conclusions Transumbilical single-port laparoscopic cholecystectomy is safe and feasible, but it is more difficult than laparoscopic cholecystectomy in terms of manipulation.Transumbilical single-port laparoscopic cholecystectomy has the potential to replace laparoscopic cholecystectomy if the operative instruments are improved.
ABSTRACT
Objective To investigate the changes of CEA levels of blood, ascites and cancer tissue in nude mice with liver metastases from colon adenocarcinoma treated by 131I-labeled anti-CEA monoclonal antibody (McAb). Methods 131I-labeled anti-CEA McAb was injected through tail vein at 10min(early treatment group), 10d(middle treatment group) and 20d(late treatment group) after the liver metastases were established respectively. 131I-labeled anti-normal mice IgG was injected through tail vein after the liver metastatic model was estabished as a control group. Results The CEA levels of blood, ascites and cancer tissue in early treatment group were significantly decreased compared with the control group (P<0.01); but, there was no difference between the early treatment group and the late treament group (P>0.05). Conclusions The CEA levels of blood, ascites and cancer nodulus in nude mice with liver metastases from colon cancer could be lowered significantly when the 131I-labeled anti-CEA McAb is used early after the liver metastasis is established.
ABSTRACT
Objective To investigate the feasibility of combined laparoscopic resection of gallbladder and other viscera. Methods The clinical data of 69 cases of combined laparoscopic resection of gallbladder and other viscera from January 1999 to July 2004 were reviewed retrospectively. Results The laparoscopic operation was successful in 69cases,and no case was converted to laparotomy.The average operation time was(85.5?18.6)min,and the time of return of gastrointestinal function was(27.3?6.2)h. The average hospitalization time after operation was(3.9?0.8)d.There were no operative or postoperative complications , and the therapeutic results were satisfactory. Conclusions The combined laparoscopic resection of the gall bladder and other viscera is safe and feasible. It is possible to treat gallbladder diseases and associated lesions of abdominal viscera simultaneously. The lesions of several organs can be treated at one operation. This can significantly decrease patients′ pain and lower the cost of treatment, and is worthy of wide usage.
