China Oncology 2001;0(03):-
Background and purpose:In all treatments of retroperitoneal tumors,surgical operation is still the only effective method which might cure the tumors.However,the patients were always in advanced stages when they were clinically diagnosed.The inferior cava of the patients always have been invaded by tumors,which is considered to be a relative surgical contraindication.This study was to explore the surgical method in treatment of retroperitoneal tumors with major blood vessels invasion,and in order to raise the resection rate and survival rate. Methods :Retrospective analysis of twelve cases which implicate major vessels and have parallel artificial vascular reconstruction during operations of retroperitoneal tumor from January 2003 to June 2007. Results :Twelve cases of retroperitoneal tumor and implicated major vessels were integrally resected,corresponding important vascular reconstructions were done,no short-term postoperative deaths. Conclusions :Retroperitoneal tumor involving abdominal important vessels is not a contraindication of radical surgical.Integrated resection of retroperitoneal tumor and implicated major vessels and corresponding important vascular reconstruction are safe,and can improve the resection rate and reduce the relapse rate,extend the survival time.

Objective To introduce the clinical application and method of endoscopic harvesting the sural nerve in the carbon dioxide gas cavity. Methods 7 cases with peripheral nerve defect were involved, including 5 men and 2 women. The length of nerve defects ranged from 5 to 8 cm, all the nerve defects were repaired by autogenous sural nerve grafting. The sural nerve were removed from 9 calves in 7 cases. Along the course of the sural nerve in the proximal calf, a transverse 1.0 to 1.5 cm incision was done for endoscope approach, another transverse 0.5 to 1.0 cm incision was done lateral to the sural nerve for operation approach. Using abdominoscope system, the sural nerves were cut and removed smoothly in the cavities which were maintained the gas pressure 10 to 15 mm Hg with carbon dioxide insufflation. All the peripheral nerve defects of 7 cases were repaired as cable graft with harvested sural nerve. Results The length of nerve graft harvested from 30 to 42 cm in 9 calves. It took about 30 minutes to harvest the nerve in each side. There was no abvious injuries found by pathologic inspection. No carbonemia and air embolism occurred on patients during operating time, no complications of hypodermic pneumatosis and hematoma occurred on all cases. All patients followed up from 6 to 10 months, the function recovery of the nerves was good. The muscle power was obtained 2 to 4 grade, the sensation was obtained S3 to S4 grade. The function recovered as fast as the traditional operation of sural nerve transfer. Conclusion The method of endoscopic harvesting the sural nerve in the carbon dioxide gas cavity with minimal incision is easy to perform. Compared with the long longitudinal incision and multiple stair-step incision, the method can get less invasive and traumatic, and good aesthetic results. This technique deserves the doctor application in clinical work.

OBJECTIVETo study the classification and individualized treatment of the terminal phalanx of thumb duplication.
METHODSFrom Apr. 2003 to Dec. 2012, 76 patients with 77 involved thumbs duplication at the level which is distal to the interphalangeal joint were retrospectively studied. Based on the morphology (the nail width and the thumb circumference) and the deviation of the thumb, we classified the terminal phalanx of thumb duplication into 5 types as Type A (no bony connection called floating thumb), Type B(asymmetry and no deviation), Type C(asymmetry and deviation), Type D (symmetry and no deviation) and Type E(symmetry and deviation). Different surgical procedures were selected according to different types. Simple excision of the smaller thumb was adopted for Type A case. Removement of the smaller thumb (usually the radial) and of the collateral ligament of the interphalangeal joint were selected for Type B. Removement of the smaller thumb (usually the radial) and reconstruction of the collateral ligament of the interphalangeal joint, as well as corrective osteotomies at the neck of the proximal phalanx were performed for Type C. The modified Bilhaut-Cloquet procedure with reconstruction of the collateral ligament of the interphalangeal joint were adopted in Type D. The classical Bilhaut-Cloquet procedure, or the modified Bilhaut-Cloquet procedure with reconstruction of the collateral ligament of the interphalangeal joint and corrective osteotomies at the neck of the proximal phalanx were performed in Type E. The results were assessed by an evaluation form for thumb duplication by the Japanese Society for Surgery of the Hand.
RESULTSAccording to our new classification standard, there were 3 cases with Type A duplicated thumbs, 36 with Type B, 13 with Type C, 15 with Type D, 10 with Type E. All the 76 patients underwent the individualized surgical treatment. The patients were followed up for 6-60 months. According to the evaluation form, excellent results were achieved in 66 thumbs, good in 9 thumbs and fair in 2 thumbs.
CONCLUSIONSThe new classification could comprehensively describe the clinical features of the terminal phalanx of congenital thumb duplication. Individualized therapy, including basic and repeated surgical procedure could be adopted for each type with satisfactory results.
