Objective To explore the clinical significance on protection of parathyroid and recurrent laryngeal nerve （RLN） by meticulous capsular dissection and exposure of RLN in thyroid lobectomy. Methods Clinical data of 452 patients who underwent thyroid lobectomy by meticulous capsular dissection and exposure of RLN in our hospital from Jan. 2010 to Dec. 2012 were retrospectively analyzed. Results All of the 452 cases underwent thyroid lebectomy successfully without death， and the operative time was 45-110min （average 60 min）， the blood loss was 5-100mL （average 20mL）. The pathological results showed that there were thyroid adenoma in 193 cases， nodular goiter in 175 cases， Hashimoto thyroiditis in 38 cases， thyroid cancer in 46 cases. After operation， 4 cases suffered RLN injury， 1 of the 4 cases recovered after removal of drainage tube， and other 3 cases recovered during 0.5 to 3.0 months. In addition， 2 cases suffered laryngeal nerve injury whose symptoms disappearred within 1 week， 5 cases suffered parathyroid founctional damage without permanent hypocalcemia whose symptom had kept 1-5 days after treatment. Three cases were reoperated because of bleeding， including branch of anterior venous bleeding in 1 case， thyroid side arterial tube bleeding in 1 case， and thyroid stump bleeding in 1 case. Twenty one cases suffered hypothyroidism in 1 month after operation， and no recurrence happened during the followed up period. Conclusions Meticulous capsular dissection can effectively protect function of parathyroid and reduce the injury probability of RLN. Exposure of RLN is safe and feasible， which plays an important role in avoiding serious RLN injury.
Objective To estimate the clinical curative effect of replacement of inverttype artificial total scapula and shoulder joint prosthesis and reserving arm with rehabilitation of function in the treatment of malignant tumor in shoulder. Methods From February 2001 and November 2004, five youth patients with primary malignant shoulder tumors were treated operatively by resection of neoplasmsthoroughly, replacement of inverttype artificial total shoulder blade and joint prosthesis, the functional reconstruction. Of them, there were 4 males and 1 female, aging from 19 to 26 years with an average of 23.6 years. Two cases were diagnosed as having osteosarcoma, one as having chondrosarcoma, and 2 as having Ewing sarcoma. After operation, the upper limbs was immobilized for 3 weeks. The rehabilitation training including passive exercise and initiative exercise. Results The average operative time was 425 min (380 to 530 min), and the blood loss ranged from 1 250 ml to1 900 ml(1 540 ml on average). The follow-up ranged from 7 to52 onths,with an average of 24.6 months. Postoperative complication included 1 case of pneumothorax, one case of shoulder incision skin part necrosis and 1 case of clavicle stump raising and pierce skin with shallow infection. No complication of postoperative incision deeply infection, nerve damage and prosthesis exposure or dislocation occurred. According to the scoring system of JOA(Japan orthopaedics association), the average score was 65 (60 to 72). The flexion and extension function of elbow joint recovered to normal. Conclusion The replacement of inverttype artificial total scapula and shoulder joint prosthesis is an efficacious method for the treatment of malignant tumor in shoulder. There are advantages of numerous adaption, wide range of motion and goodstability. It can not only reserve arm but also rehabilitate function.

Conclusion Improved longterm resection effects on H-CC is possible.
Seven hundred and eighty three cases of rectal carcinoma were treated in this hospital Jan. 1986 to Dec. 1994. There were 552 cases(70.5%)in which the tumor located in the middle and lower portion of the rectum. Of this group, 201 cases were treated with the operations of preservation of sphincter ani. The operations included transabdomino-sacral resection(5 cases), transpubic resection(5 cases), Dixon’s operation(67 cases), perineal pull through anastomosis(44 cases), Welch’s operation(68 cases), and local resection(12 cases). The 3-year survival rate was 90.9%. We consider that anal sphincter preservation is rational in the treatment of rectal cancer of middle and lower segment, As often os the radical resection and maintenauce of normal defecation is concerned, it is suitable for rectal carcinomas in Duke’s A and B1 stages. Combined treatment is necessary to prevent the recurrence and increase the survival rate.
Objective To investigate the feasibility and indication of synchronous resection of colonic carcinoma and its hepatic metastasis. Methods Radical sigmoidectomy and right hemi-hepatectomy plus left lateral segment resection were performed at the same time in a 71-year-old patient with sigmoid carcinoma and multiple hepatic metastasis. Results The operation lasted for 5 hours and 10 minutes with 300ml blood lost during the procedure. The patient recovered smoothly and was discharged 2 weeks after operation. Follow-up showed no reoccurrence up to the day of this presentation(4 months).Conclusion The operation could be performed safely by experienced surgeon in good-equipment hospital.
【Abstract】 Objective To di scus s the resect ion of tumors of pelvic ring and i t s recons truct ion ofdefects. Meth ods From January 1999 to December 2006, 48 patients with tumors in pelvic ring were treated and defects were reconstructed. There were 32 males and 16 females, aged 14-72 years(mean 45.1 years), including 12 cases of benign tumor and 36 cases of mal ignant tumor. Fourteen cases had lesions in region Ⅰ , 11 cases in region Ⅱ , 12 cases in region Ⅲ , 3 cases in region Ⅳ and 8 cases had two or more regions. The selection of surgical method: benign tumor in wing of il ium or in sacro-il iac articulation was curettaged , mal ignant tumors were resected radically or boardly . Benign or mal ignant tumor in pubis, ischium or pubic symphysis was resected radically , defects were reconstructed with plastic plate or not. For tumor affecting aceta bulum , resection of tumor and replacement of the peri- pelvic prothetic or artificial hip joint replacement were performed to reconstructthe function of hip joint. Results Twelve patients with benign tumors were followed up 12-72 months and could walk well, only 1 case relapsed locally. Thirty-six patients with mal ignant tumor were followed up 6 - 72 months, the survival time was 6-12 months in 2 cases (5.6%), 12-24 months in 2 cases(5.6%), 24-36 mongths in 6 cases (16.7%), 36-72 months in 14 cases (38.8%), and more than 72 months in 12 cases (33.3%); 28 patients (77.8%) could walk normally, 6 (16.7%) could walk with the help of walking stick , 2(5.5%) needed wheel chair to move. Compl ications occurred in 6 cases( including 2 venous thrombus,1 anoxic encephalopathy, 2 wound delayed heal ing, and 1 dislocation after total hip joint replacement); the patients’ condition took a turn for the better. Conclusion Operation is a favorable way for the treatment of pelvic tumor. Selecting convenient operation methods to resect tumors or reconstruction defects according the position of the tumor will do good favor to good results,increase the survival time and improve qual ity of l ife.
OBJECTIVE To investigate the reconstructional method of posterior wall of vagina after the resection of rectum carcinoma. METHODS From August 1991 to March 1996, 10 patients with rectum carcinoma were adopted in this study, among them, there were 4 cases belong to B stage of Dukas, and 6 cases belong to C stage of Dukes. In operation, rectum carcinoma and posterior wall of vagina were resected, and concurrent reconstruction was finished by using pedicled muscular flap of uterus. RESULTS The effect of operation were satisfactory except one case who was failed because of insufficient blood supply of the flap. Followed-up for 3-6 months, the posterior wall of vagina healed in 7 cases, the width of vagina was 2-3 fingers and the depth was 5-6 cm. CONCLUSION Reconstruction of the posterior wall of vagina with pedicled muscular flap of uterus was available in clinic. For its simplicity and feasibility, it’s suitable for the resection of rectum carcinoma in which the posterior wall of vagina was infiltrated.
The influence on the wrist stability following ulnar head resection (Darrach s procedure)was studied. A series of X-ray films and arthrography of the wrist joint were taken before and after ulnar head re- section. The results showed that after ulnar head resection the radial deviation increased 3 degree(Plt;0.01). and the ulnar deviation 11.92 degree (Plt;0.001). The position of the lunate remained unchanged. Arthrography of the wrist joint demonstrated that 11 specimens had injury of the triangular fibrocartilage.The stability of the wrist joint would no doubt be certainly affected following the ulnar head resction.
ObjectiveTo exclusively compare the short-and long-term outcomes of hepatic resection (HR) patients with multifocal tumors meeting the Milan criteria between locating in same and different sections. MethodsA total of 219 consecutive HR patients with multifocal tumors meeting the Milan criteria were divided into group SS (n=97, same section) and group DS (n=122, different sections) according to their anatomical location (Couinaud's segmentation). ResultsThe 1-, 3-, and 5-year overall survival (OS) and recurrence-free survival (RFS) rates were significantly higher in the group SS than those in the group DS (P < 0.05). The subgroup analysis showed that patients with 2 tumors and those undergoing en bloc resection were associated with better OS and RFS (P < 0.05). ConclusionsFor HCC patients with multifocal tumors meeting the Milan criteria, those with tumors locating in same hepatic section may have better longterm survival and lower HCC recurrence rates than those locating in different sections after HR.
【Abstract】Objective To establish and assess the rat model of postoperative fatigue syndrome (POFS). Methods The rat model of POFS was developed by the partial resection of the liver. The behavioral changes prior and post to operation, the disorder of nutritive intake after operation, stress reaction (pathological changes of mucous membrane in small intestine) and the hepatic albumin gene expression were observed. Results Low body temperature, lower sensitivity and reactivity were found. The serum levels of the iron, total protein, albumin, globulin and so on as the indexes of nutrition obviously dropped. The injury of the mucous membrane resulted from the stress reaction after the resection of the liver. The gene expression of the albumin decreased in the model group.Conclusion The experimental rat model of POFS by partial resection of the liver can be used for the investigation of POFS.
