Objective To investigate the significance and surgical skill for lymphadenectomy around common hepatic artery in gastric cancer. Methods Two hundred and fifty-seven cases with undergoing lymphadenectomy around common hepatic artery in gastric cancer between January 2001 and December 2006 were retrospectively reviewed. Experiences and understanding of dealing with this procedure in curative gastrectomy for gastric cancer were concluded. Results The number of dissected No.8 lymph node was 2.2±1.7, and the positive rate of No.8 lymph node was 30.35%. There were no lymphadenectomy related complications, such as anastomotic leakage, lymphatic fistula and postoperative hemorrhage in this series. Dissection around common hepatic artery lymph nodes along artery intrathecal space, division and ligation of left gastric vein at its root, and sufficient exposure of anatomic structures were important to dissection lymph nodes around the common hepatic artery. The exposure of anatomic structures included liberation of common hepatic artery by traction with the band, and the exposure of posterior side of pancreas by Kocher incision.Conclusion Being familiar with the anatomy around common hepatic artery, careful dissection, and attention to the surgical skill of lymphadenectomy are very important to improve the effectiveness of lymphadenectomy around common hepatic artery in gastric cancer.
Objective To investigate the effect and surgical skill of ultracision harmonic scalpel in curative gastrectomy for patients with gastric carcinoma. Methods From January 2007 to May 2008, the data of 152 patients who were treated by curative gastrectomy with ultracision harmonic scalpel were analyzed retrospectively. Results The mean operative time was (189.5±24.2) min. Compared with the conventional operation, the number of harvested lymph nodes (mean: 30.4±11.6) in patients treated with ultracision harmonic scalpel was increased. The application of ultracision harmonic scalpel could shorten the operation time, decrease the intraoperative blood loss and make the operation field clear. There were no postoperative complications, such as anastomotic leakage, lymphatic leakage and massive hemorrhage. And there was no death in this series. Conclusion The usage of ultracision harmonic scalpel which could improve the curative degree of lymphadenectomy is safe in curative gastrectomy for patients with gastric carcinoma.

Abstract: Objective To evaluate the longterm results of surgical treatment of tetralogy of Fallot (TOF) in adults and discuss the perioperative treatment skills. Methods From January 2000 to March 2008, 149 patients older than 14 years with tetralogy of Fallot received surgical treatment in Changhai Hospital. Among the patients, there were 78 males and 71 females with ages ranged from 14 years to 53 years and the average age was 26.3 years. Twenty patients had previous pulmonary arterial shunts before radical treatment. A total of 129 patients underwent primary radical treatment. Thirtyeight patients received a right ventricular outflow tract patch, 107 patients had transannular patch, and 4 patients had homograft aorta with valves. Results Hospital mortality was 4.0%(6/149). Four patients died of low cardiac output syndrome (LCOS), and multiple organ failure, and 2 patients died of acute renal failure. The postoperative complications included pleural effusion in 11 patients, pulmonary edema in 10 patients, severe LCOS in 9 patients, severe cardiac arrhythmia in 7 patients, reoperation for excessive bleeding in 7 patients, reintubation in 6 patients, and residual ventricular septal defect (VSD) in 5 patients (two of them had reoperation for residual VSD repair and 2 received transcatheter closure of VSD). One hundred and thirtyfour patients were followed up for 3 to 102 months (47.2±28.6 months) with a followup rate of 93.7%(134/143). Late death occurred in 2 patients, one of whom died of secondary infective endocarditis and the other had a sudden death 29 months after operation. During the followup, one patient had residual VSD (2 mm), but had a normal life. The peak systolic right ventricletopulmonary artery pressure gradient exceeded 40 mmHg in 4 patients. Two patients had severe pulmonary regurgitation. A total of 132 patients survived and had an improved life. One hundred and twentyone patients had class Ⅰ heart function (NYHA), and 11 patients in class Ⅱ. Conclusion The pathophysiologic conditions of the patients with tetralogy of Fallot in adults are very complicated due to longterm right ventricle outlet stricture and chronic hypoxia. Preoperative evaluations and postoperative treatment of complications are necessary. The systemicpulmonary arterial shunts should be performed when hypotrophy of the pulmonary arteries or left ventricles exists. Repair of tetralogy of Fallot in adults has acceptable morbidity and mortality rates with goodlongterm outcomes.
OBJECTIVE This paper is aimed to observe the long-term result of reconstruction of wrist joint by replacing distal end of radius with vascularized fibular head in patient of giant tumor. METHODS From July 1978 to November 1993, 12 cases of giant tumor of distal end of radius were treated by this procedure and followed up for 6 months to 15 years, and the movement range of wrist, grip strength, and pain were evaluated. RESULTS The painful wrist released in 11 cases, only one case still existed mild pain and felt discomfortable. The average range of movement of wrist joint was 34.05 degree in volar flexion, 52.80 degree in dorsal extension, 26.25 degree in ulnar deviation, and 19.75 degree in radial deviation, and average grip strength was 44.6 kg. Compared with the contralateral side, there were accounted for 46.2%, 72.7%, 76.1%, 80.6%, and 76.7% respectively. CONCLUSION Replacement of distal end of radius with fibular head to reconstruct wrist joint can restore function of carpal joint, which is proved to be a safe and effective method.
The authom analysed the predisposing factors for macular pucker(MP) after retinal dotachment surgery.Thirteen clinlcal risk factors correlated with the development of MP were identified, As the incidence related to various factors was compared with reported in the literature,the most significant 3 risk factors of MP were: the obvious hemorrhage accumulated in maeular area, the macular hole treated with diathernly,and the patient lay on one's back for approximately 2 weeks during postoperative retard absorption of subretinal fluid in the eyes with preoperative PVR,This suggested that the direct or indirect damage of maeular area was the major cause of development of MP. （Chin J Ocul Fundus Dis,1993,9:8-10）

ObjectiveTo evaluate clinical curative effect of sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess. MethodsOne hundred and twenty hospitalized patients diagnosed as horseshoe-shaped perianal abscess were analyzed by prospective, random, single-blind, parallel-group design method, and were randomly divided into two groups, one group of sphincter preservation method of improved minimally invasive surgery (observation group), another group of traditional method of hanging line drainage and multiple incisions of radian shape (control group). The cure rate, long-term recurrence, postoperative pain score within 9 d, hospitalization time, incision healing time, scar area after healing, postoperative anal function score and perioperative and long-term complications were compared in these two groups. ResultsAll the operations were successfully completed in these two groups. There were 56 cases of primary healing in the observation group and 55 cases of primary healing in the control group. Compared with the control group, the postoperative pain score on day 2-4 or on day 7-9 was lower (P < 0.05), the incision healing time was shorter (P < 0.05), and the postoperative anal function score was lower (P < 0.05) in the observation group. There was no incision infection and hemorrhoea in these two groups. The hospitalization time, scar area after healing, incidence rate of urinary retention, hepatic and renal dysfunction, and the total white blood cells > 10.0×109/L had no significant differences between these two groups (P > 0.05). There was no long-term recurrence, anal stenosis, and anal incontinence during following-up of 6 months in these two groups. ConclusionPreliminary research results show that sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess has a reliable clinical curative effect, fast healing, and less postoperative complications.
Objective To discuss the methods and results of the surgical treatment of apical muscular ventricular septal defects （VSD） , in order to improve the surgical outcome of this disease. Methods The clinical data of 29 patients with apical muscular VSD of Fuwai hospital through Jan. 1999 to July 2004 were analyzed retrospectively. The apical VSDwere repaired via 4 different approaches： right atrium, apical right ventriculotomy, apical left ventriculotomy and the incision of the outflow tract of right ventricle combined with apical left ventriculotomy. The operative outcomes between different approaches were analyzed and compared. Results There were 2 perioperative deaths （6. 9%）. One patient repaired via apical left ventriculotomy died of low cardiac output syndrome, the other died intraoperatively from endocardial fibroelastosis, which was confirmed by myocardial biopsy. There were residual VSD in 4 （13. 8%） patients, who were repaired via the right atrium, which did not necessitate reoperation. Other patients were discharged uneventfully. Follow up was completed {n 11 patients and extended 2 to 34 months, none of the 6 survivors had apical ventricular aneurysms. Conclusions The operative outcome of patients with apical VSD is satisfactory although the incidence of residual VSD is higher. The intraoperative transesophageal echocardiography （TEE） should be performed routinely. Surgical approach should be chosen on the actual site of the VSD at operation. Try to repair the VSD via the right atrium as possible, via the apical right ventrieulotomy if needed and try to avoid left ventriculotomy.
Objective To summarize the experience in diagnosis and treatment of primary retroperitoneal tumor (PRT). Methods Clinical data of 69 patients with PRT from June 1998 to June 2008 were analyzed retrospectively. Results Bellyache, abdominal distention, and abdominal mass were common symptoms in the patients with PRT. Ultrasound, CT, and MRI examination were effective. The major histopathological classification was soft tissue tumor, germinoma, lymphatic hematopoietic system tumors, and other rare tumors. Complete resection of tumors was performed in 42 cases, combined organs resection in 10 cases, partial resection of tumors in 11 cases, and only biopsy in 6 cases. There were 10 cases of intraoperative vessel and organ injury, which were treated by repair or vessels suturing and combined organ resection. Postoperative complications occurred in 8 cases, which were cured by conservative treatment. One patient died of hemorrhage acute stress ulcer combined multiple organ failure. The survival rates of 1, 3, and 5 years in patients underwent complete resection of tumors were 71%, 64%, and 46%, respectively. Of 11 patients underwent partial resection of tumors, 8 cases died within one year, and 3 cases died within 3 years after operation. All malignant tumor patients treated by biopsy died within one year after operation.Conclusion Synthetically using imaging examination may diagnose definitely, and to resect tumors as much as possible will improve patients’ survival.
