Objective To investigate and evaluate prevention and treatment of seroma by transposition of tissue flaps and Arista hemostatic powder after regional lymph node resection in patients with malignant tumors. Methods Twelve patients (6 males, 6 females; aged 31-81 years, with metastatic tumors underwent prevention and treatment of seroma with the tissue flaps and Arista hemostatic powder spray after regional lymph node resection. The metastatic tumors involved the axilla in 1 patient with breast carcinoma, the iliac and inguinal regions in 2 patients with carcinomas of theuterine cervix and the rectum, and the inguinal region in 9 patients, including4 patients with malignant fibrous histiocytoma（3 in the thigh, 1 in the leg）,2 patients with squamous carcinomas in the leg, 1 patient with synovial sarcomain the knee, 1 patient with epithelioid sarcoma in the leg, and 1 patient with malignant melanoma in the foot. As for the lymph node removal therapy. 1 patientunderwent axillary lymph node removal, 2 palients underwent lymph node removal in theiliac and inguinal regions, and 9 patients underwent lymph node removal inthe inguinal region. Meanwhile, of the 12 patients, 6 patients underwent transpostion of sartourius flaps with Arista hemostatic powder, 3 patients underwent transposition of the rectus abdominis myocutaneous flaps (including 2 patients treatedwith Arista spray befor the wound closure and 1 patient treated by transposition of local skin flaps with Arista spray used again),and 3 patients underwent only the suturing of the wounds combined with Arista. At the same time, of the 12 patients,only 4 patient underwent the transplantation of artificial blood vessels. Results The follow-up for 2-10 months after operation revealed that 10 patients, who had received the transposition of tissue flaps and the spray of Arista hemostatic powder, had the first intention of the incision heal with seroma cured. Nine patients were given a preventive use of Arista hemostaticpowder and therefore no seroma developed. The combined use of the transpositionof tissue flaps and Arista hemostatic powder spray achieved a success rate of 100% in the prevention or treatment of seroma. However, 1 patient developed microcirculation disturbance 24 hours after operation and underwent disarticulation of the hip; 1 patient developed pelvic cavity hydrops and died 10 months after operation. Conclusion The combined use of transposition of tissue flaps and Arista hemostatic powder spray can effectively prevent or treat seroma after regional lymph node removal in a patient with malignant tumor.
To evaluate the efficacy and the surgical procedures of submandibular sialoadenectomy by a modified retroauricular approach. Methods Between October 2008 and April 2009, 8 patients with benign submandibular gland disorders underwent removal of benign submandibular gland lesions using a retroauricular approach. There were 4 males and 4 females with an average age of 38.5 years (range, 32-54 years), including 3 pleomorphic adenoma and 5 chronic sialadenitis with sialol ithiasis. The disease duration was from 2 months to 5 years. The anterior facial vein and the facial artery were reserved only by the l igation of branching vessels in the submandibular gland. Results Submandibular sialoadenectomy were successfully performed in 8 cases. The operative time was 45-75 minutes (mean, 60 minutes). All incisions obtained heal ing by first intention. No nerve paralysis occurred, including marginal mandibular branch of the facial nerve, the l ingual nerve, and hypoglossal nerve. One patient had poor blood circulation of flap due to excessive traction during operation, but it returned normal after 24 hours without special treatment. Other flaps had good blood circulation. All patients were followed up 1-6 months (mean, 3 months). The incision scars were hidden with satisfactory appearance. Conclusion The modified retroauricular approach has some advantages such as simple operation, better cosmetic outcome, and no compl ication.
Objective
To understand status of technical realization, present development, faced problems, and application prospects of reduced-port laparoscopic surgery for rectal cancer, and to analyze safety and feasibility so as to provide theoretical and practical basis for clinical application and promotion.
Method
By searching the databases such as Medline, Embase, and Wanfang, etc., the relevant literatures about reduced-port laparoscopic surgery for rectal cancer were collected and reviewed.
Results
At present, the most common reduced-port laparoscopic surgery was the 1-port laparoscopic surgery, 2-port laparoscopic surgery, and 3-port laparoscopic surgery. The 1-port laparoscopic surgery had the effects of minimal invasiveness and cosmesis, but it was difficult to perform. The 2-port laparoscopic surgery for rectal cancer preserved as far as possible the effect of minimal invasiveness, the difficulty of procedure was reduced greatly, which was easy to be learnt and promoted. The experience of the 3-port laparoscopic surgery for rectal cancer contributed to the technical development of the 1-port laparoscopic surgery, with no need for the assisted incision for intraoperative specimen. The reduced-port laparoscopic surgery for rectal cancer was technically feasible and safe, which possessed the equal or better short-term outcomes as compared with the conventional 5-port laparoscopic or open surgery beside the radical resection for rectal cancer. However, the stringent technique for the laparoscopic surgery was necessary and it needed to overcome the learning curve.
Conclusions
Reduced-port laparoscopic surgery has some obvious advantages in minimal invasiveness, cosmesis, and enhanced recovery. More large-sample, multi-center, randomized controlled trials are eager to further confirm safety, effectiveness, and feasibility of reduced-port laparoscopic surgery for rectal cancer.
ObjectivesTo systematically review the safety of harmonic scalpel and conventional resection in superficial parotidectomy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) or cohort studies of harmonic scalpel and conventional resection in superficial parotidectomy from the inception of the database to December, 2018. Two reviewers independently screened literatures, extracted data and assessed risk of bias of the included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 studies involving 671 post-cesarean section patients (361 patients in harmonic scalpel group and 310 patients in conventional resection group) were included. The results of meta-analysis showed that: compared with conventional resection, harmonic scalpel had shorter operative time (MD=?23.82, 95%CI ?31.20 to ?16.44, P<0.000 01), less postoperative drain output (MD=?26.25, 95%CI ?38.95 to ?13.55, P<0.000 1), less intraoperative blood loss (MD=?23.78, 95%CI ?28.64 to ?18.91, P<0.000 01), shorter duration of hospital stay (MD=?1.19, 95%CI ?2.14 to ?0.23, P=0.02), and lower temporary facial nerve palsy rate (OR=0.27, 95%CI 0.14 to 0.50, P<0.000 1). However, there was no significant difference in the incidence of parotid gland leakage between two groups (OR=0.42, 95%CI 0.16 to 1.06, P=0.07).ConclusionsThe current evidence demonstrates that, compared to conventional resection, harmonic scalpel resection is safer. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Objective
To analyze clinical value of early enteral nutrition following radical resection of gastric cancer.
Methods
Seventy-six patients with gastric cancer underwent radical resection from May 1, 2016 to July 1, 2016 in the West China Hospital of Sichuan University were included according to the inclusion criteria and exclusion criteria, then were randomly divided into observation group (36 cases) and control group (40 cases). The patients in the observation group received the enteral nutrition on day 2 following the surgery, in the control group received the conventional management. The gastrointestinal recovery and the adverse reaction were compared in these two groups. The preoperative and postoperative laboratory indicators and the body weight of the patients in both groups were analyzed.
Results
① The general data such as age, gender, and body weight had no significant differences in these two groups (P>0.05). ② The first anus exhaust time and the first defecation time of the observation group were significantly shorter than those of the control group (P<0.05). ③ The adverse reaction rate of the observation group was significantly lower than that of the control group (P<0.05). ④ On admission, the serum albumin, urea nitrogen, creatinine, and lymphocyte count had no significant differences in these two groups (P>0.05). On day 5 after the operation, the serum albumin of the observation group was significantly higher than that of the control group (P<0.05). ⑤ The body weight had no significant difference in these two groups before the operation (P>0.05), which in the observation group was significantly heavier than that of the control group on day 30 after the operation (P<0.05).
Conclusion
Preliminary results of limited cases in this study show that early enteral nutrition following radical resection of gastric cancer is safe and effective, it could promote gastrointestinal function resumption and effectively improve nutritional status.
Objective Both stapled transanal rectal resection (STARR) and vaginal bridge repair are new operative techniques for treatment of rectocele transanal and transvaginal, respectively. In this study we observe the clinical outcomes for STARR as compared with vaginal bridge repair procedure. Methods The clinical data of 31 patients with obstructive defecation syndrome from January 2007 to May 2009 were retrospectively analyzed. The patients were divided into 2 groups according to different operative approach: STARR group (n=18) and bridge repair suture group (n=13). The clinical outcomes observed were operative time, blood loss, length of stay, cost of hospitalization, complication and the improvement of obstructed defecation syndrome. Results There was no difference in the age and severity in the patients of two groups. Evaluation of the clinical outcomes showed 16 (88.9%) patients in the STARR group and 6 (46.2%) in the bridge repair suture group reported improvement in symptoms (P=0.017). STARR had a shorter operative time (24.6 min vs. 33.2 min， Plt;0.01), less estimated blood loss (3.9 ml vs. 16.2 ml， Plt;0.01), more costly (10 743 yuan vs. 3 543 yuan, Plt;0.01) and a higher anal incontinenc rate but reversible. The length of stay was similar (average 6 d). Conclusion The stapled transanal rectal resection procedure is more superior to the vaginal bridge repair suture for improvement of obstructed defecation syndrome from rectocele, however, it has a higher cost and some patient with reversible slight anal incontinence after surgery.
ObjectiveTo study the risk factors affecting anterior resection syndrome of rectal cancer.
MethodsSixty-seven patients with low rectal cancer who performed anus preserving operation in Second Artillery General Hospital from August 2013 to October 2014 were screened out based on inclusion and exclusion criteria. Forty-two cases received low anterior resection (LAR), 25 cases received intersphincter resection (ISR). Patients were followed-up for 1 year. The severity of anterior resection syndrome was evaluated by using score system for anterior resection syndrome. The patients' age, gender, body mass index (BMI), TNM stage, surgical mode, surgical approach, anastomotic height, prophylactic colostomy, adjuvant chemotherapy, and radiotherapy were used as research indicators, and to evaluate the impact to anterior resection syndrome.
ResultsThe single factor analysis showed that the surgical mode, preventive stoma, radiotherapy, anastomotic height, and age were related to the severity of anterior resection syndrome (P < 0.05). Logistic regression showed that the surgical mode (OR=4.506, 95% CI: 1.220, 16.640, P=0.024) and radiotherapy (OR=14. 688, 95% CI: 3.200, 67.429, P=0.001) were related to the severity of anterior resection syndrome.
ConclusionSurgical mode and radiotherapy are the independent risk factors of anterior resection syndrome.
ObjectiveTo explore the surgical technique and clinical effect of endoscopic assisted transaxillary breast tumor resection in the treatment of benign and malignant breast tumors. MethodsThe clinical data of 18 patients received endoscopic breast tumor resection from September 2020 to December 2021 in the Department of Breast Surgery, West China Hospital, Sichuan University, were retrospectively analyzed to evaluate the feasibility, tumor safety and postoperative cosmetic effect. There were 7 patients with benign breast tumors (a benign breast tumor group) and 11 patients with early breast cancer (a malignant breast tumor group). Breast-Q and Scar-Q questionnaires were used to evaluate postoperative quality of life and satisfaction of patients. ResultsEndoscopic breast tumor resection was performed successfully in 18 female patients, among whom 12 patients received day surgery. The mean age of benign and malignant breast tumor groups was 29.6±11.6 years and 46.7±14.3 years, the mean tumor size in pathological examination was 3.3±2.1 cm and 2.0±0.8 cm, and the operative time was 138.9±57.0 min and 177.3±46.3 min, respectively. One patient had positive resection margin and underwent intraoperative extended resection in the malignant breast tumor group. All the patients were successfully followed up, and the mean follow-up time of benign and malignant breast tumor groups was 6.8±4.0 months and 8.7±4.9 months, respectively. No complications or tumor recurrence occurred. The scores of psychosocial status, sexual well-being, chest wall status and breast satisfaction decreased one month after surgery and basically recovered to the preoperative level in one year, and the score of scar appearance increased to 64.6±5.9 points one year postoperatively. ConclusionEndoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.
ObjectiveTo explore the effect of clinical nursing pathway on rehabilitation indicators in patients who had undergone transurethral resection of prostate (TURP).
MethodsA total of 241 patients underwent TURP between July 2010 and March 2014 were randomly divided into path group (121 cases) and control group (120 cases). The nursing results of the two groups were observed.
ResultsThe complication rate of bladder spasm, secondary hemorrhage, urethral stricture in path group were lower than those in the control group with significant differences (P<0.05).
ConclusionThe performance of clinical nursing pathway on TURP patients may reduce the complications rate, and promote the health economics indicators and quality of care.
ObjectiveTo investigate the relationship between metastatic lymph node ratio (MLNR) and prognosis of patients after radical resection of distal gastric cancer.MethodsWe retrospectively analyzed the clinicopathological data of 408 patients undergoing radical resection of distal gastric cancer (D2 or D2+ lymph node dissection) in Department of Gastrointestinal Surgery in the Affiliated Hospital of Southwest Medical University, from January 2010 to January 2014. Then we explored the influence of MLNR on the prognosis after radical resection of distal gastric cancer.ResultsWithout distinguishing pTNM staging, the overall survival situation of patient with MLNR≥0.15 and patient with MLNR<0.15 was statistically significant (χ2=3.775, P=0.046); when patients with staging of pTNM Ⅰ, there was no statistically significant MLNR could be calculated; when patients with staging of pTNM Ⅱ, the overall survival situation of patient with MLNR≥0.14 and patient with MLNR<0.14 was statistically significant (χ2=3.110, P=0.029); when patients with staging of pTNM Ⅲ, the overall survival situation of patient with MLNR≥0.10 and patient with MLNR<0.10 was statistically significant (χ2=1.631, P=0.004). Multivariate analysis showed that depth of invasion (pT stage) and MLNR were independent prognostic factors for prognosis of patients after radical resection of distal gastric cancer (P<0.05).ConclusionMLNR is a good prognostic indicator for patients with distal gastric cancer after radical resection.
