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.
Objective To investigate the impact of laparoscopic versus. open hepatic resection for liver cancer on clinical rehabilitation and humoral immune function in patients organism. Methods Forty-four patients of laparoscopic and open left-lateral sectionectomy from January 2010 to June 2012 were selected， including 22 patients of laparoscopy group and 22 patients of conventional laparotomy group. The levels of IgG， IgA， IgM， C3， C4， C reactive protein （CRP）， IL-2， IL-6， and TNF-α in peripheral blood of patients on the last day before operation， first day and 5th day after operation were determinated by using ELISA assay. At the same time， the operative time， intraoperative bleeding， hospitalization time， and complications after operation between two groups were compared. Results The postoperative analgesic using time， first time eating， and hospitalization time in laparoscopic group were （1.9±0.8） days， （2.2±0.5） days， and （6.3±1.3） days， respectively， they were shorter than that in conventional laparotomy group （P＜0.05）. The operative time， intraoperative bleeding， complication rate， and mortality in two groups were not significant differences（P＞0.05） . Compared with before operation， the levels of C3， C4， IgA， IgG， IgM， and IL-2 on the first day after oper-ation in two groups were obviusly reduced， the levels of CRP， IL-6， and TNF-α on the first day after operation in two groups were significantly increased. The levels of C3， C4， lgA， IgG， lgM， and IL-2 on the first day after operation in conventional laparotomy group were significantly decreased than that in laparoscopic group （P＜0.05）. On the 5th day after operation， the levels of C3， C4， lgA， IgG， lgM， and IL-2 of laparoscopy group increased， the levels of CRP， IL-6，and TNF-α were reduced，that were no difference compared with before operation. Compared with before operation，the levels of C3， C4， lgA， IgG， lgM， and IL-2 of conventional laparotomy group were still at a low level state， and the levels of CRP， IL-6， and TNF-α were still at a high level state on the 5th day after operation. Conclusions Laparoscopic resection of liver cancer after operation， the patients’ recovery are quickly， and the impact on humoral immune function of laparoscopic radical resection for liver cancer patients is significantly less than that conventional laparotomy.
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 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.
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.
Objective To evaluate the methods of the pedicle screw-rod fixationsystem combined with allograft bone or polymethylmethacrylate (PMMA) for the reconstruction of pelvic girdle after the complete resections of primary malignantbone tumor and the metastatic lesion of ilium. Methods From July 1999 to July2004, 16 patients with iliac malignant bone tumor were treated with the techniques of the complete resection and reconstruction. There were 9 males and 7 females at the age of 16 to 80 years. The 10 patients with primary malignant bone tumor included 4 cases of chondrosarcomas, 3 cases of osteosarcomas, 2 cases of Ewing sarcomas, and 1 case of malignant giant cell tumor of bone. The 6 patients with the metastatic lesion consisted of 2 cases of breast carcinoma, 1 case of lung carcinoma, 1 case of kidney carcinoma, 1 case of thyroid carcinoma and 1 case of prostate carcinoma. A solitary skeletal metastatic lesion was demonstrated in all metastases. There were 2 cases of stage ⅠA and 8 cases of stage ⅡB in primary malignant bone tumor according to the Enneking classification. The pedicle screwrod fixationsystem combined with allograft bone was used to reconstruct the pelvic girdle in primary malignant tumor. The patients with metastases underwent the pedicle screwrod system fixation with PMMA or without PMMA. The postoperative complication of reconstruction, local recurrence and bone healing were investigated. The postoperative function was analyzed according to the method reported by Enneking. Results The average followup was 35.6 months (5 to 65 months). Of all patients, 2had suspected deep infection, 2 had internal fixation loosening and 1 had nonunion of allograft bone. The mean healing time of the osteotomy site was 5.8 months (4.2 to 8.4 months). No immune rejection was seen. There were 2 patients with local recurrences, 3 patients with pulmonary metastases and 2 deaths due to metastases. The average functional score was 24.8(82.7%) in 8 survival. The functional results also were classified as excellent in 4, good in 3 and fair in 1. The median survival was 11.8 months (4.6 to 48.5 months) in metastases. Four patientshad lived for 1 year or longer after surgical intervention. The internal fixation loosening occurred in 2 patients, new destruction in 3 patients and no infectionoccurred. All patients immediately alleviated the pain and could walk with or without support after operation. At follow-up after 1 year, the average functional score was 21.7(72.3%). The functional results also were classified as excellent in 2 and good in 2. Conclusion Because of less complication and good function, the pedicle screwrod fixation system combined with allograft bone orPMMA are advisable for the reconstructions of pelvic stability after the complete iliac resections of primary malignant bone tumor and the metastatic lesion.
Objective To improve the curative resection rate of hilar cholangiocarcinoma (H-CC).Methods Lileratures about surgical treatment of H-CC were collected and reviewed. Results The crucial points are as follow: ①Early diagnosis; ②Recognition of the invasion to liver; ③Rational resection of the tumor with associated vessels; ④Reduction of postoperative complications. Conclusion Improved longterm resection effects on H-CC is possible.
Objective To investigate and evaluate the clinical features, diagnostic methods, surgical management and postoperative adjuvant therapy of thymic carcinoma so as to improve the treatment outcome. Methods Forty-three patients of thymic carcinoma , surgically intervened and pathologically confirmed in Peking Union Medical College Hospital through June 1961 to June 2004, were retrospectively analysed. Complete resection of the tumor was performed in 15 patients, partial or incomplete expiration in 23 , exploratory thoracotomy and biopsy in 5. Results All tumors were found inencapsulated and invading the surroundings,including pericardium, superior vena cava, left or right innominate vein, rnediastinal pleura, phrenic nerve and lung. In this series there was no perioperative death. Eight patients died within the first year postoperatively, 4 died within the second year postoperatively, 2 and 1 patients died in the 5th and 8th year postoperatively respectively. Through half to 18 years follow-up, according to the life table method, the 1,3,5 and 8 year survival rate were 68.29%, 56. 67%, 41.56% and 27. 71% respectively. Conclusions Thymic carcinoma is different from malignant thymoma in clinical manifestations, radiological features, pathological characteristics and prognosis, hence it is very important for thoracic surgeons to pay more attention to those differentiation. Chest CT is an effective method for diagnosis of thymic carcinoma. It is emphasized on that aggressive radical resection of the tumor with involved tissue or organs, even removal of superior vena cava and subsequent reconstruction of vessel, will effectively extend long-term survival. Postoperative radiotherapy and combination adjuvant chemotherapy, especially based on cisplatin, play a significant role in improvement of prognosis.
ObjectiveTo investigate the systemic stress responses after laparoscopic resection in colorectal cancer patients.MethodsSixty patients were randomized into the laparoscopic resection group (30 cases) and open resection group (30 cases) from October 2001 to September 2002 in our hospital.Analgesic dosages, recovery time of intestinal peristalsis, postoperative temperatures, C reactive protein(CRP), IL6 and white blood cell (WBC) counts were recorded after operation. ResultsThe changes of postoperative temperatures and WBC counts showed no significant difference between two groups.But in the laparoscopic resection group, the recovery time of intestinal peristalsis, postoperative analgesic dosages, CRP and IL6 significantly decreased (P＜0.01,P＜0.05).ConclusionCompared with traditional open resection, laparoscopic resection of colorectal cancer can diminish the systemic stress responses and decrease the injury to patients.
ObjectiveTo compare and evaluate the application of two types of chest drainage in patients who had undergone the lung lobe resection.
MethodWe retrospective analyzed the clinical data of 240 patients who underwent left lobe resection. The patients were divided into a single conventional drainage group with single chest drainage tube (normal group) and a single conventional drainage tube combined with drainage of disposable surgical negative pressure drainage ball (NPBD) (combination group). There were 140 patients including 86 males and 54 females at mean age of 48.76± 4.92 years in the normal group. There were 100 patients including 58 males and 42 females at mean age of 48.37± 4.56 years in the combination group. We compared the outcomes between the two groups.
ResultThe postoperative pathological results revealed there were 12 patients with tuberculosis (TB), 87 patients with squamous carcinoma, and 41 patients with adenocarcinoma in the normal group; 5 patients with TB, 66 patients with squamous carcinoma, and 29 patients with adenocarcinoma in the combination group. There were statistical differences in postoperative hospital stay (11.35± 2.78 d vs. 9.33± 2.46 d), chest drainage tube indwelling time (6.75± 2.10 d vs. 8.28± 2.10 d), total volume of chest drainage (1 176.07± 384.62 ml vs. 926.50± 22.35 ml) with P values less than 0.001 between the normal group and the combination group. No statistical difference was found between the two groups in complications (P>0.05).
ConclusionSingle conventional drainage tube combined with drainage of disposable surgical negative pressure drainage ball (NPBD) has more advantages than single conventional chest drainage tube drainage, and is worth to be applied popularly in clinic.
