Colorectal cancer is a threat to human health, the disease rate of stage Ⅱ colorectal cancer is increasing. Some prognostic factors have been researched, and the number of harvested lymph nodes is a very important factor. Harvesting more lymph nodes will reduce the relapse rate and increase the survival rate. It remains controversial for the minimum number of lymph nodes, and UICC and AJCC recommended that the minimum number was 12. Some factors will influence the number of harvested lymph nodes,for ex-ample, the patient's situation, tumor itself, surgeon and pathologist's skills , and so on.

OBJECTIVETo investigate the therapeutic effect of primary reconstruction of skin avulsion injury with bilateral anterolateral thigh flaps combined with thorax umbilicus flap or latissimus dorsi flap.

METHODSFrom June 2005 to Aug. 2011, 4 cases with skin avulsion injury on both feet were treated. The bilateral anterolateral thigh flaps, including with anterolateral thigh cutaneous nerves, were transferred to cover the feet plantar. The thorax umbilicus flap or latissimus dorsi flap were used to cover the feet dorsum.

RESULTSAll the skin avulsion injury were reconstructed primarily. All the flaps survived completely with good cosmetic and functional results. The patients were followed up for 6 months to 2 years with good sensory recovery (two point discrimination: 14-18 mm).

CONCLUSIONThe skin avulsion injury on both feet can be primarily reconstructed by bilateral anterolateral thigh flaps combined with thorax umbilicus flap or latissimus dorsi flap.

OBJECTIVETo investigate the clinical effect of lateral superior genicular composite tissue flap for tissue defect.

METHODSThe axis line of flap is the lateral thigh vertical midline. The cutaneous branch is inserted 4 cm near the femoral lateral epicondylus. The anterior border is the elongation line along patellar lateral border. The posterior margin is the hinder margin of femoral biceps. The lower border is the horizontal line along the upper line of patella. The composite flaps were used in 18 cases with soft tissue defects in extremities, 11 cases with clacaneus tenden defects and 16 cases with bony nonunion. Results From Mar. 2002 to Sept. 2013, 45 cases were treated with the composite tissue flaps. The flaps size ranged from 6 cm x 3 cm to 17cm x 9 cm. All the flaps survived completely. Blood supply crisis happened in 2 cases, which was released by reanastomosis. The patients were followed up for 1 - 2. 5 years with satisfactory aesthetic and functional results. All the bone defect and nonunion were healed. Good healing was also achieved in donor sites. 8 months after operation, knee joint function is evaluated as good by hospital special surgery knee score (HSS).

CONCLUSIONLateral superior genicular compostie tissue flap can be used to reconstruct soft tissue defect, bone defect and tenden calcaneus defect in one stage.

Objectives To approach the method and clinical effect on tendo calcaneus and complex tissue defect with microsurgery repair.Methods Retrospective summary the methods of 356 cases with tendo calcaneus and complex tissueserious defect,which repaired by different microsurgery from June 1994 to March 201 1.Two type were divided on account of different degree of serious tendo calcaneus and complex tissue defect.Type A:the length of tendo calcaneus defect was less than 3 cm,and cutaneous deficiency is less than 3 cm × 20 cm.Direct suture (166 cases) or Abraham retrograde V-Y method (72 cases)was used to repair endo calcaneus defec,anfregional flap metastasis was used to repair cutaneous deficiency.Two hundred and thirtyeight cases were used by those methods,including of lateral heel flap repair(23 cases),medial plantar island flap(58 cases),instep island flap(40 cases),above medial malleolus flap(48 cases),above ateral malleolus flap (24 cases),sural nerve nutrient vessel flap (29 cases) gastrocnemius muscle flap (16 cases).Type B:the length of tendo calcaneus defect was more than 3 cm,and cutaneous deficiency was more than 3 cm × 20 cm.Direct suture could not repair tendo calcaneus,the complex tissue flap free grafting was used to primary repair tendo calcaneus and complex tissue defect.One hundred and erghteen cases were used by those methods,including of tensor fasciae latae flap free grafting (52 cases),lateral above knee complex tissue flap free grafting (26 cases),latissimus dorsi muscle fascia flap free grafting (24 cases),rectus abdominis muscle front sheath flap free grafting (16 cases).Three hundred and fifty-six cases were repaired by these methods,including 238 cases of regional flap transfer 118 cases of tissue flap free grafting.Results In 238 cases of regional flap transfer,two hundred and twenty-six cases were successful,and 12 cases were partly success,which were wound healing by change dressings.In 118 cases of tissue flap free grafting,one hundred and nine cases were successful,and blood vesse articulo were happened to 8 casess,which were success by operations research,and 1 case was failure which had to use another tissue flap.Follow-up visit was dane from 1.0 year to 4.5 years after operation (average 3.2 years).Functional assessment according to the Thermann ralted the results as excellent in 240 csaes,good in 86 cases,common in 22 cases and worse in 8 cases.The fineness rate was 91.6％.Conclusion Microsurgical repair is a good method to tendo calcaneus and complex tissue defect,different method and strategy selected actively by tissue defect degree of tendo calcaneus and complex tissue can achieve satisfactory functional rehabilitation purpose.

Objective To evaluate the efficacy of serum PCT level in deciding the development and progno-sis of sepsis and its conrrelation with APACHE Ⅱ scoring.Methods 56 patients of sepsis accepted intensive care treatment and were all given APACHE Ⅱ scoring within the first 24 h after admission to ICU.The PCT level at dif-ferent time(1 d,3 d,5 d-7 d,10 d after admission)was detected.All these patients were divided into survival group and death group based on the 28-day fatality.Results The PCT level declined gradually with the treatment and it decreased obviously from the third day in comparison with the original level before admission [survival group/death group:(2.98±0.48)μg/L/(4.98±0.66)μg/L vs(4.04±0.50)μg/L/(6.02±0.50)μg/L](P

Objective To compare the short-term results of laparoscopic-assisted with open surgery for primary rectal cancer in elderly patients. Methods The medical records of forty-nine elderly patients (≥70 years) with laparoscopic-assisted resection and fifty-five cases (≥70 years) with open surgery for rectal cancer were retrospectively reviewed. Results There were no thirty-day mortality in both groups. Operative procedure and operating time did not differ significantly in laparoscopic-assisted group (LAG) and open group (OG), and blood loss was significantly greater in OG (P =0.031). The rate of postoperative complications was lower (12.2 % vs 25.5 %) in LAG than that in OG, but the difference was not statistically significant (P = 0.088). The time to faltus (3.26 d vs. 4.49 d) and time to liquid diet (3.98 d vs.5.56 d) were significantly shorter in LAG than that in OG. Both the circumferential and distal margins were negative. The number of identified lymph nodes were similar for LAG and OG (mean 13.31 vs 13.13, P =0.886). Conclusion Laparoscopic-assisted rectal resection for elderly patients is safe and feasible, with less complications and blood loss, and rapid intestinal recovery compared with open surgery.

Objective To investigate the prognosis of local resection in patients with low rectal cancer, and assess surgical indications for this procedure. Methods One hundred and twenty-four patients with low rectal cancer from Jan 1975 to Dec 2006 were analyzed, the clinicopathologic features and surgical, outcome were examined as prognostic factors. Survival rate was estimated by Kaplan-Meier method and compared by Log-Rank test, prognostic factors were analyzed by multivariate COX proportional hazards model. Results The 5-year survival rate of 124 patients underwent local resection was 90.7 %(97/107), there were 4.8 %(6/124) patients with complications and 15.3 %(19/24) ones with local recurrence.The infiltration, vascular invasion, the size of tumor and the histological grade were significant prognostic factors of overall survival, but gender, age, the tumor site and the macroscopic type were not. Multivariate analysis indicated that the tumor infiltration were independent poor prognostic factor. Conclusion Local resection is suitable for Tis and T1 low rectal cancer, and those with high local recurrence factors should undergo radical resection. Strict follow-up and adjuvant therapy is necessary for local excision.

Objective To investigate the feasibility of laparoscopic radical resection for colorectal cancer in patients with respiratory dysfunction. Methods A total of 64 patients with colorectal cancer with respiratory dysfunction simultaneously admitted in our hospital. Following the principles of en-bloc resection, thirty-six patients underwent laparoscopic radical resection, and 28 underwent open resection. Results The time of postoperative oxygen inhalation was shorter in laparoscopic group than that in open resection group (3.5 d vs 4.6 d) (P<0.05), and independently expectorating was better in laparoscopic group than that jn open resection group (P <0.05). The time to endotracheal intubation removal (21.2 min vs 23.9 min) and oxygen saturation were no significant difference between laparoscopic group and open resection group. One case got lung infection in open resection group, both groups had no atelectasis, respiratory failure and urinary infections case. Conclusion Laparoscopic surgery is feasible for colorectal cancer in patients with respiratory dysfunction.

Objective To summarize the experience in nursing patients with gut leak after liver transplantation. Methods Two patients with recurrent gut leakafter liver transplantation underwent surgical repair. The nursing measures included strict observation of postoperative disease, observation of drainage fluid and abdominal signs, early nutritional support, good psychological nursing and health education. Results Gut leak occurred in the two cases again after liver transplantation.One case was treated with repair again and the other with end-stage ileotomy and ileostomy. The patients were discharged after medication and nursing care. Conclusions The close postoperative observation of the disease, observation of drainage fluid and abdominal signs can prompt the discovery of intestinal re-perforation.The early nutritional support plays an important role in the rehabilitation of patients with gut leak after liver transplantation.Mental care and health education can enhance patient's confidence in treatment.

Objective To analyze the application and effect of non-penetrating vascular and tubular tissue closure system in radical resection of adenocarcinoma of pancreatic head combined with venous resection and reconstruction.Methods A retrospective analysis was made on the clinical data of 78 patients with pancreatic head cancer who underwent radical resection of venous vessels from Feb 2014 to Feb 2018.According to the intraoperative venous resection and anastomosis,the patients were divided into vascular clip group (41 cases) and traditional suture group (37 cases).The preoperative data,intraoperative and postoperative recovery of the two groups were analyzed and compared.Results There were no perioperative deaths and no significant differences in perioperative complications between the two groups (P ＞ 0.05).The anastomotic time of the clip group was (18.6 ± 3.3) min,which was significantly shorter than that of the traditional suture group (39.7 ± 8.5) min,(P ＜ 0.05).There were no significant differences in operation time,intraoperative bleeding volume,ICU time,hospital stay and anastomotic stenosis between the two groups(P＞ 0.05).Conclusion It is safe and feasible to use vascular clip in venous vascular reconstruction in radical resection of carcinoma of the head of the pancreas combined with venous vascular resection.
