ABSTRACT
Objective:To discuss the procedure for correction of inverted nipple using tiny incision with primary breast ducts reserved.Methods:A total of 35 patients (63 sides) with primary inverted nipples from January 2006 to March 2019 were reviewed retrospectively. Tiny radial incisions were made on the areola around the base of the inverted nipple which had been pulled out. Without skin removed, shorten fiber bundles which caused nipple inverted were totally cut and released. While the primary breast ducts were preserved, purse-string suture was taken around the base of the nipple. The nipple protector was prepared by ourselves, and the nipple was pulled and suspended for 2-6 months.Results:Sixty-three sides of 35 patients with inverted nipples were successfully corrected by this minimally invasive surgery. There was no nipple necrosis. One patient developed mild swelling 3 weeks after operation, and the swelling subsided after symptomatic anti-inflammatory treatment. The average follow-up period was 39 months. After removing the nipple protector, 2 sides (2/63) had a certain degree of recurrence. The rest of the nipples had ideal shape, no obvious scar, good nipple feeling, and retained the possibility of lactation.Conclusions:The procedure for correction of inverted nipple using tiny incision with primary breast ducts reserved has advantages of minimal invasion, safety, less pain, while retaining the possibility of lactation in the future. The clinical effect is satisfactory. It is especially suitable for the correction of type Ⅰ and type Ⅱ inverted nipples.
ABSTRACT
Objective To evaluate the clinical effect of circumvertical mastopexy with internal shaping using inferior dermal-glandular flap for correction of breast ptosis.Methods From April 2010 to November 2017,33 cases of breast ptosis were treated in our department.The patients required nipple elevation of 3-6 cm and had unpleasing result after circumareolar mastopexy were treated with the technique of circumvertical lift with breast suspension and internal shaping with inferior dermal-glandular flap which pedicle was on the inframammary crease and tack technique for removing excessive skin precisely.Results 33 cases had their drainage tubes removed at the 2～3 days and suture removed at the 12～14 days postoperatively.All had primary healing of incision and no complications such as necrosis of NAC and dehiscence of incision occurred.Elastic bra was asked to wear for three to six months and then stable shape was achieved.Follow-up lasted for 6-60 months.All cases were satisfied with their new breast shape.Conclusions Circumvertical mastopexy with internal shaping using inferior dermal-glandular flap is a simple and effective method with relatively short scar and good shape for correction of the medium grade breast ptosis.
ABSTRACT
Background: Currently, many problems are still controversial on performing out of digestive tract operation through endoscopic submucosal tunnel. Aims: To evaluate the feasibility and safety of endoscopic mediastinal exploration via esophageal submucosal tunnel. Methods: Endoscopic mediastinal exploration was performed via esophageal submucosal tunnel in two healthy swine. A 5 cm submucosal tunnel was created with blunt dissection. The mucosal incision was closed by hemostatic clips, and penicillin was used prophylactically. Two weeks later, after reexamined by gastroscopy, the animals were sacrificed and the esophagus was obtained for macropathology and histopathology. The survival rate, wound healing and complications were observed. Results: The mediastinal organs such as aorta, trachea, and pericardium were identified clearly during exploration. All the animals survived with no obvious complications. Gastroscopy and histopathology showed good wound healing two weeks after operation. Taking autopsy as standard, the anatomical structures were accurately identified under endoscopy. Conclusions: Animal experiment revealed that mediastinal exploration via transesophageal endoscopic submucosal tunnel is feasible and relatively safe.
ABSTRACT
Hemorrhagic anaemia caused by chronic gastrointestinal bleeding is a common complication of BRBNS that has the greatest impact on the patient′s quality of life, even life-threatening. Traditional treatments cannot slow down the overall progress of the disease. The curative effect is limited and has certain limitations. Sirolimus can effectively treat vascular malformations of the soft tissues, and it can control gastrointestinal lesions to correct iron deficiency anemia caused by bleeding, improve quality of life, and can inhibit disease progression and improve prognosis. This new emerging medication may become one of the powerful treatments for BRBNS in the future.
ABSTRACT
Objective@#To investigate the clinical effect and safety of tramadol hydrochloride sustained-release tablets for subcutaneous venous malformation polidocanol sclerotherapy.@*Methods@#The experimentation was designed in block randomization. 106 patients with subcutaneous venous malformations from May 2016 to November 2017, which in line with the inclusion criteria, were randomly divided into experimental group and control group, with 53 cases in each group. Experimental group patients took 100 mg tramadol hydrochloride sustained-release tablet 1 hour before operation, while control group patients took nothing. Both group underwent polidocanol foam injection therapy guided by the color ultrasound, to observe the effect of operative analgesia, postoperative analgesia (VAS grade) and complications. The data was analyzed by SPSS 19.0 software. Comparison between two groups was done with independent sample t test and P<0.05 was considered statistically significant.@*Results@#The pain sensation(VAS grade) in surgery in experimental group(3.02±1.118)were significantly reduced than control group(6.30±1.514) (t=-12.701, P=0.000). 2 hours after operation the pain sensations decreased in both groups, but experimental group(0.23±0.577)were still better than which in control group(0.60±0.987)(t=-2.403, P=0.018). Three patients of experimental group(5.7%) felt mild nausea, and no other severe complications nor adverse effects occured.@*Conclusions@#Oral tramadol hydrochloride sustained-release tablets is one of safe, simple and effective way to achieve satisfactory preemptive analgesia for venous malformation polidocanol foam sclerotherapy.
ABSTRACT
Objective To study the pathological mechanism of aseptic necrosis of breast tissue after long-term breast augmentation injected with polyacrylamide hydrogel (PAHG).Methods We included patients who had no obvious clinical symptoms and underwent surgical removal of the PAHG in our hospital,excluding patients with a history of breast prosthesis implantation.Extracts were collected,and then underwent a careful gross observation and serial sections followed by HE,Mallory,and toluidine blue staining,to observe the histological structure of collagen fibers and inflammatory cells.Immunohistochemistry for CD31 and a-smooth muscle actin (a-SMA) antibody was used to further identify vascular endothelial cells and vascular smooth muscle cells,respectively.Analysis of the correlation between injection time and the incidence of different pathological changes were done.Results We included 22 females (mean age 39.14 years,range 22-55 years) who requested surgical removal of the PAHG.The mean duration of PAHG injection was 9.27 years (range 4-14 years).They had no clinical symptoms or only had induration,deformation and displacement.The basic pathological changes of local tissue included foreign body reaction and chronic inflammation,fibrosis and tissue necrosis;and half of the tissue had also histological changes,such as small vascular smooth muscle layer thickening,lumen stenosis,etc.No significant correlation was found between the pathological changes and the duration of the disease and the clinical symptoms.Conclusions Patients with PAHG injection for augmentation mammoplasty can histopathological changes of local tissues even without experiencing discomfort.The tissue necrosis in some patients may be caused by foreign body reaction and inflammatory reaction.It may also be due to local ischemia caused by small vascular smooth muscle hyperplasia,luminal stenosis etc.
ABSTRACT
Objective To explore a more efficient surgical method to cure axillary osmidrosis through a comparative study on results from two surgical treatments of axillary osmidrosis in the armpit area.Methods 72 patients were randomized into two groups,in which 36 patients (group A) with micro-incision simple liposuction and 36 patients (group B) with dissection and excision of subcutaneous tissue from axillary folds.The clinical outcomes in the two groups were comparatively analyzed,based on surgery time,effect,complications,scarring and recovery time.Results The total efficiency of axillary osmidrosis treatment was 100％ after 6-12 months clinical follow-up towards two groups.There was no significantly statistical difference on the effect of both groups.Micro-incision simple liposuction was obviously superior to dissection and excision of subcutaneous tissue from axillary folds based on surgery time,complications,recovery time,scarring and armpit hair survival rate.The two groups were significantly different (P＜0.05).Conclusions Minimally invasive simple liposuction,as a treatment for axillary osmidrosis is a method with more effectiveness and reliability.It is a more acceptable approach to patients in view of safety and convenience,smaller and invisible scarring,fewer complications,and less recovery time.
ABSTRACT
Objective To study arterial distribution of rectus abdominis musculocutaneous flap and to evaluate whether it can be divided into several units for reconstruction. Methods The arteries of the rectus abdominis musculocutaneous flap were studied on 60 sides of cadavers by dissection and angiography. Results The superior epigastric artery (SEA) and the inferior epigastric artery (IEA) continued in a longitudinal direction. Most of their branches took on a typical spiral configuration and communicated with each other within muscle above the level of umbilicus. Many perforating arteries penetrated through the anterior rectus sheath to get to the overlying skin, but the highest concentration of major perforators were in the paraumbilical area. The inferior epigastric artery was more significant than superior epigastric artery in supplying the skin of the musculocutaneous flap. Based on thefstudies of the vascular anatomy of muscles, we could classify arterial distribution into 3 types: type Ⅰ (SEA 26.5 %, IEA 34.6%) revealed a single main intramuscular artery: type Ⅱ (SEA 64.7 %, IEA 48.1%) had two major intramuscular branches; type Ⅲ (SEA 8.8%, IEA 17.3 %) revealed three intramuscular branches. Our anatomic studies showed that the superior and inferior epigastric artery bifurcated or divided into more than two main branches in the majority of cases (SEA 73.5%, IEA 65.4%). Conclusion The rectus abdominis musculocutaneous flap could often be divided into several regions for breast construction which is based on the distribution of each branch of the artery.
ABSTRACT
Objective To summarize clinical experience of reconstruction of breast suspensory structure in correction of mild-to-moderate breast ptosis.Methods Through a periareolar incision,the flabby deep layer of the superficial fascia beneath the upper breast gland was completely removed.Then the gland was lifted up to the normal position and the superior pole of the gland was fixed to the pectoral fascia at the second intercostal space.By using the dermal bra technique,an appropriate amount of skin was excised,and the dermis was fixed to the anterior surface of the breast gland. Or a monofilament polypropylene mesh was implanted and fixed to the anterior or posterior surface of the upper breast gland.Postoperatively,remarkable scar fibrosis reaction developed to form strong supporting structures just like natural ones.Glandular plication or implant augmentation was simultaneously employed to enhance the projection,if necessary.Results A total of 32 cases of mild-to-moderate breast ptosis was treated with this technique,including 10 cases of mastopexy only,20 cases of mastopexy with implant augmentation,and 2 cases of mastopexy using monofilament polypropylene mesh.The operation time was 90~150 min(mean,110 min).The intraoperative blood loss was 30~100 ml(mean,58 ml).No complications such as nipple or areola necrosis or sensory disturbance were found.Follow-up observations for 6~12 months(mean,11.3 months) showed a satisfactory rate of 90.6%(29/32).Conclusions Reconstruction of breast suspensory structure is a simple,safe,and effective method for correction of mild-to-moderate breast ptosis without hyperplasia of mammary glands.
ABSTRACT
Objective To evaluate the effect of intratumor injection of Pingyangmycin for the treatment of superficial hemangioma and venous malformation.Methods From May 2005 to March 2008,42 patients with superficial hemangioma or venous malformation,including 17 men and 25 women(aged 3 months to 51 years)were treated in our hospital by injecting pingyangmycin intratumorally.Among the patients,18 had hemangioma,20 had venous malformation,and 4 had the both.The injection consisted of a mixture of Pingyangmycin(8 mg),2% lidocaine(2 ml),normal saline(2 ml),and dexamethasone(2.5 mg).The volume of the tumor was evaluated before the injection.And then the mixture was injected intratumorally at a density of 0.5 mg/cm2(0.3 mg/cm2 for the patients with ulcers in the skin or mouth).For the patients who had residual tumor after the first injection,a second treatment was performed in 10 days to 3 weeks or longer.The maximum dosage of Pingyangmycin for a single injection was 8 mg,and the maximum total dosage was 70 mg.Results One year after the treatment,85.5%(47/55)of the patients were cured,and 12.7%(7/55)were improved.The total effective rate was 98.2%(54/55).Conclusions Injection of Pingyangmycin is an effective and safe method for superficial hemangioma and venous malformation with low blood flow.The maximum injection density is 0.5mg/cm2.
ABSTRACT
Objective To sum up the experience of copper needle embolization for huge subcutaneous cavernous hemangioma. Methods Eighteen cases of huge hemangioma, located at the face and neck (3 cases), the upper limbs (5 cases), or the lower limbs and buttocks (10 cases), respectively, were treated from 1996 to 2003. Needles made from copper wire 1~3 mm in diameter were inserted into the lesions, through the skin directly or under the guidance of color Doppler ultrasonography. The copper needles were left in place for 1 week, with or without 4~6 V direct current circulated for 5~10 min twice. Results The therapeutic outcomes included: the shrinking and sclerotization of the hemangioma with the disappearance of postural changes (18 cases), the decrease of circumference of the involved limb (13 cases), the change of the lesion skin from blue-purple to light or normal in color (4 cases), the subsidence or disappearance of swelling and heavy feeling of the involved limb (5 cases), and the regression of the lesion and the reduction of blood flow under color ultrasonography (14 cases). Conclusions Copper needle embolization is a simple, effective and relatively less invasive method for the treatment of huge subcutaneous cavernous hemangioma that is difficult to be resected. It at times may be the only applicable option for children.
