Objective To analyze the causes and the reoperation therapies after salvage limb surgery with prosthesis for bone tumors. Methods The retrospective analysis was performed on 85 patients undergoing the limb salvage operation with prosthetic replacement for tumors from January 1994 to December 2004. Ofthe patients, 21 (13 males and 8 females, aged 18-58 years) underwent reoperations for various reasons. All the diagnoses were pathologically confirmed(10 patients with osteosarcoma, 4 with chondrosarcoma, 5 with giant cell tumor of the bone, 2 with osteofibrosarcoma). The distal femur was involved in 9 patients, proximal tibia in 8, proximal femur in 2, proximal humerus in 1, and acetabulum in 1. According to the Enneking surgical grading system, there were 5 patients in ⅠB and 16 in ⅡB. The time between the first operation and the reoperation was 2 weeks to 20 years. The common reasons for the reoperation were tumor recurrence in 8 patients, prosthetic loosening in 5, no healing of the incision in4,joint dislocation in 3, and implant fracture in 1. The amputation and the prosthesis revision were respectively performed on 6 patients, extensive resection ofthe tumor on 3, the myo-skin flap translocation on 4, internal hemipelvectomy without reconstruction on 1, and open reduction on 1.Results The follow-up in18 patients for 1-5 years (average, 3 years and 4 months) revealed that 4 patients died of osteosarcoma with pulmonary metastasis. The other 14 patients had no tumor recurrence or loosening of the prosthesis, and the incisions healed well. The assessment on the joint function was performed on 13 of the 18 patients and the results were as follows: excellent in 2 patients, good in 5, fair in 4, and poor in 2, with a satisfaction rate of the reoperation with limb salvage of 84.6%and an excellent-good rate of 53.8%. Conclusion Tumor recurrence is the most common reason for the reoperation after the limb salvage with prosthesis for tumors, and loosening of the prosthesis is an important reason, too. By therules of the bone tumor limb savage, the limb salvage operations can also beperformed, which can achieve a satisfactory result of the limb function.
ObjectiveTo evaluate the clinical efficacy of tricuspid valve re-operation after left cardiac valve surgery. MethodsWe retrospectively analyzed the clinical data of 23 patients underwent tricuspid valve re-operation in the Affiliated Drum Tower Hospital of Medical School, Nanjing University from January 2009 to November 2014. There were 3 males and 20 females with a mean age 53.48±10.79 years ranging from 34 to 71 years. The average body mass index of the 23 patients was 21.77±2.42 kg/m2. We followed up all the patients in outpatient department or through telephone for 3 months to 5 years. ResultsAll surgeries were operated under cardiopulmonary bypass. There were 15 patients underwent operation through medisternal incision and 8 patients underwent operation through the fourth intercostal incision of right anterolateral side. The mean operation time was 284.35±56.16 minutes and the mean time of cardiopulmonary bypass was 138.61±46.91 minutes. One patient died postoperatively and 2 patients chose to discharge automatically after operation. The other 20 patients recovered and discharged uneventfully. We followed up the patients for 3 months to 5 years. One patient underwent permanent pacemaker therapy for atrioventricular block, 3 patients accepted pharmaceutical therapy for atrial arrhyttmia, 1 patient underwent re-operation for infectious endocarditis of left cardiac artificial valve. and the follow-up conditions of the rest patients were well. Besides, the follow-up data showed that there was a mild regurgitation in 3 patients underwent tricuspid valve plasty. ConclusionTricuspid valve re-operation after left cardiac valve surgery can take multiple surgical pathways and strategies. The clinical effect has been proved and the midterm follow-up condition is well, but we still need the long-term follow-up for the further effect.
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 investigate the clinical effects and safety differences of open surgery and laparoscopy primary lesion resection combined with D2 lymph node dissection in the treatment of elderly patients with advanced gastric cancer. Methods One hundred and forty elderly patients with advanced gastric cancer were chosen and randomly divided into two group including open operative group (70 patients) with primary lesion resection combined with D2 lymph node dissection by open operation and laparoscopic surgery group (70 patients) with primary lesion resection combined with D2 lymph node dissection by laparoscopy; and the operative time, intraoperative bleeding amount, the levels of PaCO2 in operation, liquid diet eating time, postoperative anal exhaust time, postoperative gastric tube indwelling time, postoperative ambulation time, the level of haemoglobin (Hb) after operation, the hospitalization time, the number of lymph node dissection, the survival rate with followed-up and postoperative complication incidence of both groups were compared. Results There was no significant difference in the operative time between 2 groups (P>0.05). The intraoperative bleeding amount, the level of PaCO2 in operation, liquid diet eating time, postoperative anal exhaust time, postoperative gastric tube indwelling time, postoperative ambulation time, the level of Hb after operation and the hospitalization time of laparoscopic surgery group were significantly better than open operative group (P<0.05). The level of PaCO2 in operation of laparoscopic surgery group was significantly higher than open operative group (P<0.05). There were no significant difference in the gastric lymph node dissection number and the peripheral lymph node dissection number of gastric artery between 2 groups (P>0.05). There were no significant difference in the survival rates between the 2 groups after 3-year followed-up (P>0.05). The complication incidence after operation of laparoscopic surgery group was significantly lower than open operative group (P<0.05). The quality of life scores of patients in laparoscopic surgery group were significantly higher than those in open operative group on 7 days and in 3 months after operation, and the difference were statistically significant (P<0.05). Conclusion Compared with open operation, primary lesion resection combined with D2 lymph node dissection by laparoscopy in the treatment of elderly patients with advanced gastric cancer can efficiently possess the advantages including minimally invasive, shorter recovery time and less postoperative complications.

Objective To investigate the relationship between surgical operation and hypophosphatemia, to observe the possible damage of hypophosphatemia and to assess the value of postoperative phosphate supplementation. Methods Sixty four male SD rats were randomly divided into 2 groups, Group Ⅰ, drinking a specially prepared solution to reduce their phosphate storage, Group Ⅱ, drinking water as a control. All received common bile duct ligation 3 weeks later. The serum biochemical data including phosphate level were obtained before and after operation. Then half of rats in each group were supplied with NaH2PO4 5-day survival rates were analyzed with statistic methods and their vital organs were observed under electron microscope. Results The phosphate level of each group was descended after operation. The group with phosphate shortage before operation (group Ⅰ) had a greatest fall of phosphate and average arterial pressure. The phosphate-supplied rats had a minor change of vital organs under electron microscope scan and higher 5-day survival rate compared to others in this group.Conclusion Abdominal surgery may induce postoperative hypophosphatemia, especially when the phosphate has been lacking before operation. Severe hypophosphatemia, superimposed on surgical trauma, enhances the damage to the body. Prompt supplement of phosphate will improve the prognosis of surgical operation.
ObjectiveTo investigate the short-term effectiveness of one-stage radical debridement and total hip arthroplasty (THA) in the treatment of active tuberculosis of the hip. MethodsBetween January 2006 and June 2011,one-stage radical debridement and THA were performed on 12 cases (12 hips) of active tuberculosis of the hip.There were 7 males and 5 females,aged 18-60 years (mean,46.3 years).The disease duration ranged from 6 to 24 months (mean,10.5 months).According to Babhulkar and Pande staging criteria,5 cases were at stage Ⅲ and 7 cases were at stage IV.One case had sinus,and 2 cases had previous pulmonary tuberculosis.Preoperative hip range of motion was (35.83±9.25)°; hip Harris score was 36.83±6.44.Erythrocyte sedimentation rate (ESR) was 45-90 mm/1 h (mean,62.4 mm/1h); C-reactive protein (CRP) was 19-50 mg/L (mean,33.6 mg/L).Perioperatively all the patients accepted the regular anti-tuberculous medication. ResultsThe results of histopathological examination and PCR detection were positive for tuberculosis bacillus.Postoperatively the incisions healed primarily.All the patients were followed up 25-60 months (mean,40.8 months).The ESR and CRP returned to normal level with no liver injury.Tuberculosis recurrence occurred in 1 patient at 4 months after operation,which was cured after revision.X-ray film showed no prosthesis shift,prosthesis loosening,or sinus tract.At 18-24 months after operation,the bilateral sides had the same bone density,which was similar to that at the final follow-up.Hip range of motion was significantly improved to (107.08±13.56)° (t=14.571,P=0.000).Hip Harris score was significantly increased to 88.00±10.78 (t=16.750,P=0.000). ConclusionA combination of one-stage radical debridement and THA is a safe method to treat active tuberculosis of the hip,which can relief symptoms and improve hip function,with low recurrence and satisfactory short-term effectiveness.
Objective To discuss the way and management of cardiopulmonary bypass （CPB） through intubation of femoral artery and femoral vein for completely video assisted cardiac operations, Methods CPB were set up through femoral artery and femoral vein in 85 patients on heart surgery by video assisted thoracotomy. Thirtyeight patients were diagnosed as atrial septal defect （ASD）, forty-three patients were diagnosed as ventricular septal defect （VSD）, and four patients were mitral valve stenosis and mitral incompetence （MS＋MI）,The video assisted thoracotomy was used to repair ASD, VSD and mitral valve replacement （MVR）. Results For all patients the durations of CPB and aortic cross-clamping time was 30-179 min（91.7±27.4 min）, 6-103 min（37.2±6. 1 min）. In one patient, the CPB was set up again for repairing of residual leak. The endothelium of femoral artery was lacerated during withdrawing the cannula in 2 patients. Conclusion The video assisted thoracic operation with CPB and by intubation of femoral artery and femoral vein to perform heart operation are feasible and safe. All patients are recovered well.
ObjectiveTo evaluate the role of triclosan-coated polyglactin 910 suture in reducing wound infections of emergency gastrointestinal surgeries. MethodsThis was a prospective, randomized, controlled, single center study. From May 2009 to August 2010, 412 patients underwent emergency gastrointestinal operations in our department, 198 of them were chose randomly as experimental group using triclosancoated polyglactin 910 suture for abdominal wall closure， 214 using traditional braiding suture were taken as control. The risk factors for wound healing were analyzed, and wound infection rate was compared between two groups. ResultsThere were no significant differences of gender, age, body mass index, combined diabetes, use of immunosuppressant, and glucocorticoid steroid, type of incision, intraoperative bleeding volume, and operation time between two groups (Pgt;0.05). Wound infection rate of experimental group 〔3.0% (6/198）〕 was significantly lower than that of control group 〔11.7% (25/214), Plt;0.001〕. Especially in subgroup of type Ⅲ incision and operative time more than 120 min, wound infection rate was significantly different between experimental group and control group 〔3.5%(5/141) versus 14.3%(22/154); 3.3%(2/60) versus 21.2%(11/52) respectively, Plt;0.001〕. ConclusionTriclosancoated polyglactin 910 suture can reduce wound infection rate of gastrointestinal emergency operations, especially with type Ⅲ incision and operation time ≥120 min.
In order to decrease the risk of operation, complete release of scar tissue and reduce the recurrence after operation, from February 1994 to March 1997, seventy-three cases of severe cicatricical adhesion on the submental-thoracic region were treated with release and resection of scar tissue, and delay skin graft. The grafted skin was survived completely after operation. The result from the release of scar tissue of the cervical region was good. The physiological angle of submental-thoracic angle was recovered. It was thought that two-stage operation for submental-thoracic cicatricial adhesion would decrease the risk of operation and be advantageous to the release of contracted soft tissue of anterior cervical region and reduce the recurrence of contracture. The interval between the two stages of the operation was 2 to 3 days, which did not increase the rate of infection of the wound. The shortcomings including increase of pain to patient and prolong the time in hospital.
