改良带蒂胸大肌皮瓣修复头颈部晚期恶性肿瘤术后复杂缺损的临床应用

背景与目的：带蒂胸大肌皮瓣因为具有多种优点一直是头颈部组织缺损修复应用的经典组织瓣。当今,随着显微技术普及和提高,游离组织瓣逐步取代了带蒂组织瓣。然而,临床上并非所有病例均适宜接受游离组织瓣修复手术,邻近带蒂组织瓣更安全可靠。拟通过改进胸大肌皮瓣的制备及修复方法,探讨改良带蒂胸大肌皮瓣在修复头颈部晚期恶性肿瘤术后复杂缺损时的应用。方法：在皮瓣设计方案及制备方法等多方面改进胸大肌皮瓣,修复头颈部晚期恶性肿瘤术后复杂缺损患者51例。结果：51例改良胸大肌皮瓣全部存活,缺损区修复后外形和供区外形情况满意,缺损区功能得到良好的恢复,供区术后功能损伤最小化。结论：胸大肌皮瓣在设计及制备方法等多方面的改良,提高了对头颈部恶性肿瘤术后复杂缺损修复的范围及修复的距离,减少皮瓣坏死的概率,术后供区和受区外形、功能效果满意,目前仍然是头颈部恶性肿瘤术后缺损的重要修复手段之一。     

A novel technique of raising a pectoralis major myocutaneous flap through the skin paddle incision alone

A good reconstruction should not only be functionally and aesthetically sound at the recipient site but also cause least possible cosmetic aberration of the donor site. The pectoralis major myocutaneous (PMMC) flap continues to be one of the most commonly used flap for head and neck reconstruction in this part of the world. Conventionally, once the skin paddle over the pectoralis major muscle is marked, a line is drawn joining the outer edge of the skin flap extending to the apex of the anterior axillary skin fold or midclavicular point to expose the underlying pectoralis major muscle and harvest the flap. We intend to suggest a novel technique, in which the pectoralis major muscle is exposed by raising the skin around the skin paddle incision alone without making any further extension.     

Clinical significance of pectoralis muscle strength in elderly patients with idiopathic pulmonary fibrosis

Introduction:Investigations of muscle dysfunction in patients with idiopathic pulmonary fibrosis (IPF) are limited to peripheral muscles. However, decreased thoracic muscle mass is known and deterioration of chest wall muscle strength is not clear.Objective:The aims of the present study were to evaluate pectoralis muscle strength located on the chest wall and to investigate the relationship of spirometric measurements and respiratory muscle strength with pectoralis muscle strength.Methods:Elderly patient with IPF (mean disease duration 7.47±7.04 years) and the age-and sex-matched healthy volunteers were recruited in this cross-sectional study. The pulmonary function test was performed by a portable spirometer for spirometric variables and a gas analyzer for diffusing capacity for carbon monoxide (DL_CO). Maximal inspiratory (MIP) and expiratory pressure (MEP) were measured with mouth pressure device. Modified Medical Research Council Dyspnea Scale (MMRC) was used to determined dyspnea severity. The pectoralis muscle strength was assessed isometrically during shoulder joint horizontal adduction movement with a handheld dynamometer.Results:A total of 17 patients with IPF (9 males, mean age 69.06±3.94 years) and 19 healthy controls (10 males, mean age 70.95 ±4.99 years) were included. Patients with IPF had lower pectoralis muscle strength than healthy controls (p<0.001). Significant relationships were found between pectoralis muscle strength and MIP (r=0.79, p<0.001), MEP (r=0.81, p<0.001), FEV₁% (r=0.54, p=0.02), FVC% (r=0.68, p<0.003) and DL_CO (r=0.61, p=0.009). With multiple linear regression analysis, pectoralis muscle strength was the only independent predictor of FVC% (adjusted R²=0.37, p<0.05).Conclusion:In patients with IPF, pectoralis muscle strength decreases and is associated with pulmonary function. In particular pectoralis muscle strength is likely to have an important impact on FVC%. Therefore, we consider that this test should be included routinely in chest diseases and rehabilitation clinics. The trial was registered U.S. National Library of Medicine clinical trial registry (https://clinicaltrials.gov, Trial ID: {"type":"clinical-trial","attrs":{"text":"NCT04803617","term_id":"NCT04803617"}}NCT04803617)     

The preservation of minor pectoralis muscle in axillary dissection for breast cancer: functional and cosmetic evaluation.

We have evaluated, in two groups of 50 patients each submitted to axillary dissection for breast cancer (10 mastectomies and 90 conservative procedures), the advantage of the preservation of the minor pectoralis muscle. This muscle was preserved in one group and removed in the other. Whereas in the immediate postoperative period complications (shoulder pain, functional impairment, quantity or duration of serum drainage from the axilla) were the same in the two groups, at longer follow-up (more than 6 months after surgery) the patients whose pectoralis minor muscle was preserved showed a reduction in the incidence of partial atrophy and fibrosis of the pectoralis major muscle. Patients treated with conservation of the pectoralis minor muscle showed this atrophy in 6% of cases vs 54% observed in the other patients. This fact may be related to disruption of the pectoral nerves, which are in close contact with the pectoralis minor during their course from the brachial plexus to the pectoralis major muscle.

Local recurrence in the pectoralis muscles following modified radical mastectomy for carcinoma

Local recurrence following treatment of carcinoma of the breast is usually associated with systemic metastases. However, there are some cases in which local disease is the only manifestation of recurrence, and long-term survival can be achieved in these patients with aggressive treatment. Ten cases of apparent isolated metastasis in the pectoralis muscle following modified radical mastectomy are presented and good results were obtained in some cases utilizing surgery or x-ray therapy or a combination. It is worth noting that reconstruction would not have interfered with the detection of these recurrences, if the implant had been placed under the muscle.     

Abnormal muscles that may affect axillary lymphadenectomy: surgical anatomy

Purpose The present study aimed at summarizing and presenting the anomalous muscles that a surgeon might encounter during axillary lymphadenectomy (AL). Methods For this purpose, both the anatomical and surgical literature was reviewed and an anatomical study on 107 cadavers was carried out. Furthermore, based on the anatomical features of the anomalous muscles that came up during our study and taking into consideration the landmarks of the AL, we further analyzed the complications that may arise from each of these muscles, along with their preoperative and intraoperative recognition and management. Results The literature review revealed that there are three supernumerary muscles that may affect the AL, namely the Langer’s axillary arch, the pectoralis quartus and the chondroepitrochlearis muscles, as well as the aplasia of the lower part of the pectoralis major muscle. Eight out of the 107 (7.48%) cadavers that we dissected had such an abnormal muscle in the axilla. Specifically, the axillary arch was found unilaterally in five cadavers (4.67%) and the pectoralis quartus muscle was present unilaterally in three cadavers (2.8%). One cadaver had both an axillary arch and a pectoralis quartus muscle in the right side. The abdominal and almost the whole sternocostal portion of the pectoralis major as well the pectoralis minor muscle were absent in one cadaver (0.93%). The chondroepitrochlearis muscle was not found in any of the cadavers that we dissected. Conclusions The present study offers the necessary preoperative knowledge for recognizing these muscles during AL, avoiding thus the complications that may arise from them.

Resection of the thoracic wall in oncology

Based on our experience with 12 patients who underwent wide anterior chest wall resection in our institute, we attempt to define the indication of the different techniques for reconstruction by musculo-cutaneous flaps according to the extent of resection and location in the chest wall. The pectoralis major flaps are simple and important in the reconstruction of sternal defects; especially when dense retrosternal fibrosis has already developed after radiotherapy. The latissimus dorsi flaps are reliable and thick and suitable for coverage of major tissue loss. A new technique is also described for reconstruction of major anterolateral chest wall defects as well as sternal defects by a latissimus dorsi osteo-muscular flap. The external oblique musculo-cutaneous flaps are used to cover defects in the lateral chest wall below the 5th rib. Pedicled omental flaps are complementary flaps and can be used when muscle flaps are insufficient to replace significant tissue loss. Respiratory problems arising from paradoxical chest wall movement are temporary and may be encountered in the immediate post-operative period. Because of the development of fibrosis and of a better adaptation of the patient, this condition is well tolerated during the month following operation.     

Transpectoral anterior approach to the axilla for lymph node dissection in association with mastectomy preserving both pectoral muscles and their neurovascular bundles

In Patey's mastectomy, which is still the most common operation for breast cancer, axillary node dissection (AND) is performed through the base of the axilla after retracting the pectoralis major muscle and excising the pectoralis minor muscle (some surgeons preserve the latter). This has the disadvantage of inadequate exposure of the axilla and the risk of damage to the neurovascular bundles supplying the pectoral muscles, which in the long run may lead to atrophy of these muscles. A transpectoral anterior approach to the axilla for AND in association with mastectomy was attempted in 115 cases to obviate the above-mentioned disadvantages. The approach included: 1) splitting of the pectoralis major between the clavicular and sternal fibers; 2) mobilization and swinging of the pectoralis minor into different directions by means of a sling to facilitate AND at selected levels. The major advantages of this approach were: 1) total preservation of both pectoral muscles with their neurovascular bundles maintained the normal anatomy and function of the shoulder; 2) the axilla was directly approached through the anterior wall instead of through the base; in this way the axillary contents were exposed almost at surface level; 3) the dissection plane could be limited to anterior to and below the axillary vein and the risk of postoperative lymphedema could thus be minimized; 4) change of position of the ipsilateral arm was not necessary; 5) the duration of surgery was reduced. Monoblock ablation of significant and suspected tissues, maintaining the normal anatomy and function of the shoulder, could be easily accomplished with this approach.     

Modification of muscle-preserving radical mastectomy.

A technical improvement of the muscle-preserving radical mastectomy for breast cancer is presented. In this procedure, the Sulcus interpectoralis, located between clavicular and sternocostal parts of the pectoralis major muscle, is split bluntly and spread apart. Then, the pectoralis minor muscle is severed near its attachment to the coracoid process and an axillary dissection is thereby easily and thoroughly accomplished. The effectiveness of lymph node dissection by this method was ascertained when the number of the lymph nodes removed by this procedure was compared with that removed by the conventional muscle preserving mastectomy (Madden's operation) and the radical mastectomy. Ninety-three patients treated by this operation have shown a satisfactory cosmetic appearance and a good prognosis when compared with patients treated by the standard radical mastectomy.     

A case of locally recurrent breast cancer in which phlebothrombosis of the right leg after hormonal therapy using a high dose of toremifene citrate

A 72-year-old female had undergone mastectomy at the age of 67 for right breast cancer (T2a, n1 alpha, positive for ER). In the surgery the pectoralis muscle was preserved. For adjuvant therapy, 20 mg/day of tamoxifen was orally administered for 5 years. Six years after surgery, relapse was detected in the right major pectoralis muscle. Irradiation at this site and oral administration of 120 mg/day of toremifene citrate were started. The patient had a medical history of diabetes, and the control of her blood sugar was poor. About 2 months after oral administration of toremifene citrate was started, flares with blebs and swelling were observed in the right lower leg, suggesting acute phlebothrombosis of the right lower limb. The symptoms were ameliorated by intravenous administration of heparin and an antibiotic. In administering a high dose of toremifene citrate to patients with complications, careful follow-up is needed.     

Prospective evaluation of pectoralis muscle invasion of breast cancer by MR imaging

BACKGROUND: Assessment of pectoralis muscle invasion is important for treatment planning for breast cancer. We evaluated the usefulness of breast magnetic resonance (MR) imaging for the detection of tumor invasion of the pectoralis muscle in breast cancer patients. MATERIALS AND METHODS: A total of 306 breast MR examinations were performed preoperatively. Three-dimensional gradient echo sequences, at a section thickness of 1.5 or 2 mm were obtained with administration of gadolinium-DTPA. All patients underwent surgery. RESULTS: In 33 breasts, disruption of the fat plane between tumor and muscle was noted. Seven of 33 cases showed muscle enhancement contiguous to enhanced tumors. Pathology reports indicated that 5 of 7 of the tumors involved muscle invasion. Of the 2 false positive cases, one showed muscle enhancement because of a previous biopsy, and the other was incorrectly interpreted as showing muscle enhancement. Of the 26 breasts which did not demonstrate muscle enhancement, none were found at surgery to have tumor involvement. CONCLUSION: Enhancement of the pectoralis muscle correlates well with muscle invasion, but there are a few potential pitfalls. Disruption of the fat plane between tumor and muscle, without muscle enhancement, might not indicate tumor involvement of the pectoralis muscle.
