In order to observe the morphological feature and blood supply of the pedicled trapezius myocutaneous flap, dissection was carried out on 114 sides of 54 cadavers. It was demostrated that trapezius muscle had multiple sources for its blood supply, including (1) dorsal scapular artery; (2)transvers cervical artery; (3) occipital artery and (4)spinal perforating artery. The dorsal scapular artery may originate from the same stem with the transvers cervical artery (68.4%), or originate seperatly (31.6%). Thirteen patients had radical resection for malignant tumour of head and neck, and were combined with pedicled trapezius myocutaneous flap, in which 6 with upper trapezius myocutaneous flap and 7 with lower trapezius myocutaneous flap. The results were fairly good. the advantages and disadvantages of the lower and upper trapezius myocutaneous flaps as well as the pectorlis major myocutaneous flap were discussed.
Objective To evaluate the effect of the combined method of l iposuction and semicircular periareolar incision glandular organ partial resection in the treatment of gynecomastia. Methods From June 2004 to June 2006, 40 patients, aged 11-41 years old, were treated, with no-nodule (n=10), nodule (n=22) and female-breast-l ike with nodules (n=8). Three patients were unilateral and 37 ones were bilateral. The levels of serum prolactin, luteinizing hormone, foll icle stimulating hormone, estradiol, testosterone and cortisol were normal in 38 patients, while in the other 2 patients, the levels ofserum prolactin, luteinizing hormone, foll icle stimulating hormone and estradiol were higher than normal, and the testosterone level was lower. Li posuction alone was performed in 10 no-nodule patients (lei po-type), and combined l i posuction and semicircular periareolar incision glandular organ partial resection were conducted in the other 30 patients (lei po-glandular type). Results Except for 2 cases in which hematoma and a small amount of effusion were found on the first and second day postoperatively and then obtained heal ing by first intention right after hematoma removal in time, all the other patients’ incisions obtained heal ing by first intention. Ni pple numbness occurred in 3 cases on the first day postoperatively and no special treatment was conducted. There was still nipple hypesthesia in these 3 cases after 6-month follow-up. There were no compl ications such as hematoma, effusion, nipple and mammary areola necrosis, and nipple hypesthesia in other patients. All the 40 patients were followed up for 6-24 months (13 months on average). They were satisfied with their chest figures and no recurrence was observed. Conclusion The combined method of l iposuction and semicircular periareolar incision glandular organ partial resection in the treatment of gynecomastia has many advantages, such as safe, micro-scars, natural and beautiful male breast figures as well as high patients’ satisfaction.
Objective To explore the impact of the severity of low anterior resection syndrome (LARS) on the quality of life in patients with rectal cancer. Methods Literatures published from January 2012 to August 2020 in the Cochrane Library, PubMed, Embase, CNKI, WanFang and other databases were searched according to the search terms. Study screened, data extracted, and quality evaluated were conducted by three reviewers independently, and the RevMan 5.4 software was used for meta-analysis. Results Seven studies, involving 1 616 patients were included. Meta-analysis results showed that the functional scores (including overall health status, physiological functioning, role functioning, emotional functioning, cognitive functioning, and social functioning) of patients with major LARS were lower than those of patients with no/minor LARS (P<0.001). Except for appetite loss, the symptom score (including fatigue, nausea and vomiting, pain), shortness of breath, insomnia, constipation, diarrhea, and financial difficulties of patients with major LARS were higher than those of patients with no/minor LARS (P<0.01). Conclusion Major LARS has a greater impact on the quality of life of patients after surgery than no/minor LARS.
Objective To summarize the application and progress of common autologous organ transplantation (AOT) techniques. Method A literature review and summary of previous and recent studies on common AOT was performed, including autologous liver transplantation, autologous kidney transplantation and intestinal autotransplantation techniques. Results AOT solved the issues of bleeding that cannot be controlled by in vivo resection of lesions, difficulties in vascular reconstruction, and the inability to radically resect lesions, and extended the indications for treatment of partially diseased conditions. Conclusions The AOT technique has an ameliorating effect on the tight donor situation in China, providing more potential donors. And the application of the AOT technique effectively avoids the usage of postoperative immunosuppressive drugs and the progression of lesions due to waiting for allogeneic organ transplantation. However, the clinical benefit in malignant tumors remains to be further investigated.
ObjectiveTo explore the effectiveness of the usage of artificial bone of tricalcium phophate in sellar floor reconstruction after transsphenoidal microsurgery for pituitary adeoma. MethodsBetween January and December 2014, 85 patients with pituitary adema underwent transsphenoidal microsurgery, and the clinical data were retrospectively analyzed. "Sandiwich" was used for sellar floor reconstruction in 46 cases (control group), and "sandiwich" combined with the artificial bone of tricalcium phophate in 39 cases (trial group). There was no significant difference in gender, age, disease duration, size of tumor, invasiveness, and the degree of damage to the sellar floor between 2 groups (P>0.05). ResultsTotal removal and subtotal removal of tumors were achieved in 39 cases and 7 cases of the control group, and in 33 cases and 6 cases of the trial group, showing no significant difference between 2 groups (Z=-1.303, P=0.193). Cerebrospinal leakage occurred in 8 cases of the control group and in 10 cases of the trial group during operation, showing no significant difference (Z=-1.748, P=0.080). The case number of cerebrospinal leakage in the control group (4 cases) was significantly more than that in the trial group (0) after operation (P=0.020). The time of gauze removal in the trial group (3 days) was significant shorter than that in the control group[(4.3±1.6) days] (t=2.236, P=0.033). The patients were followed up 3-14 months in the control group and 5-13 months in the trial group. No cerebrospinal leakage occurred during follow-up. ConclusionSellar floor reconstruction with artificial bone of tricalcium phophate is safe, and it can reduce cerebrospinal leakage and shorten the time of gauze removal.
The effect of proximal subtotal or total gastrectomy by choosing abdominal median incision plus left 7-9 ribs resection in 32 cases of upper gastric cancer had been studied. There was 1 case of residual tumor cells at the esophageal margin, 1 case of hydrothorax and hydrops of costal bed, no costal chondritis, pneumothorax and fistula formation. We consider that it is better to choose abdominal median incision plus left ribs resection in patients with upper gastric cancer in which subphrenic esophageal invasion is under 2cm of length and the function of heart or lung is severely damaged.
Objective To explore the effect of ex-vivo liver resection and autologous liver transplantation (ERAT) combined with complicated hepatic venous reconstruction for end stage hepatic alveolar echinococcosis (AE). Method Theclinical data of one case with hepatic AE who treated in Organ Transplantation Center of Sichuan Provincial People’s Hospital in December 2017 was analyzed retrospectively. Results Pre-operative examination and intraoperative exploration revealed the hepatic vein (HV) and retrohepatic inferior vena cava (RHIVC) were invaded widely. We successfully initiated operation through vivo and ex-vivo hepatic AE resection, portal vein reconstruction, right/short/right inferior HV reconstruction into a wide mouth outflow with the assist of autogenous saphenous vein, and then piggyback autologous liver transplantation by wide mouth outflow-artificial inferior vena cava anastomosis (side to side). The operative time was 16 hours, and blood loss was 1 000 mL approximately. The patient was admitted routine treatment after hepatectomy. The inject low-molecular-weight heparin sodium was admitted for anticoagulant therapy 24 hours after operation. This patient recovered smoothly without bile leakage, bleeding, infection and liver failure, and so on. The patient was discharged uneventfully 14 days after operation, and there was no special situation during the6 months follow-up period. Conclusions ERAT is an ideal surgical method for end stage hepatic AE. Hepatic parenchymal transection and individual duct reconstruction, especially hepatic outflow reconstruction, are the key steps for ERAT.
ObjectiveTo understand the biological behavior of primary squamous cell carcinoma of thyroid (PSCCT), and provide references for its clinical diagnosis and treatment.MethodThe latest domestic and foreign reports of PSCCT were collected and analyzed.ResultsIn the diagnosis of PSCCT, the possibility of metastasis of squamous cell carcinoma to thyroid should be excluded. It often presented with hoarseness, local obstruction, and the median survival time was about 12 months. The treatment mainly relies on complete surgical resection.ConclusionPrimary squamous cell carcinoma of thyroid is a rare disease with rapid disease progression, poor overall prognosis and limited therapeutic options.
Three-dimensional (3D) visualization technology can well characterize lung nodules, accurately locate lung nodules, accurately identify lung anatomical structures, shorten operation time, reduce intraoperative and postoperative complications, and make thoracoscopic precise lung resection safer and more efficient. However, the mastery of 3D reconstruction technology in some hospitals still needs to be improved. Due to the time and economic cost of 3D printing, the development of this technology is restricted. With the application and improvement of 3D visualization technology in more centers in the future, the development of precise lung resection will be more extensive. This article reviewed the progress on 3D visualization technology in thoracoscopic precise lung resection.
From 1972 to 1990,121 cases of bone tumor were treated by segmental resection of tumor and followed by artifical joint re- placement. All of the prostheses were designed and manufactured by our hospital. One hundred and two cases were followed up for an average of 7.4 years and the curative rate with the affected limbs preserved was 85.28%. The indication, the advantages and disadvantages, the material and the type of artifical joints, and the assessment of functional reconstruction following operation were discussed.
