Bronchopleural fistula is a severe complication with a high mortality rate that occurs after pulmonary resection. Several treatment options have been suggested; however, it is a challenge to treat this condition without recurrence or other complications. In this case report, we describe the successful performance of a pedicled latissimus dorsi myocutaneous flap transfer, with no recurrence or donor site morbidity.

Objective : Complete sellar floor reconstruction is critical to avoid postoperative cerebrospinal fluid (CSF) leakage during transsphenoidal surgery. Recently, the pedicled nasoseptal flap has undergone many modifications and eventually proved to be valuable and efficient. However, using these nasoseptal flaps in all patients who undergo transsphenoidal surgery, including those who had none or only minor CSF leakage, appears to be overly invasive and time-consuming. Methods : Patients undergoing endoscopic endonasal transsphenoidal tumor surgery within a 5 year-period were reviewed. Since 2009, we classified the intraoperative CSF leakage into grades from 0 to 3. Sellar floor reconstruction was tailored to each leak grade. We did not use any tissue grafts such as abdominal fat and did not include any procedures of CSF diversions such as lumbar drainage. Results : Among 200 cases in 188 patients (147 pituitary adenoma and 41 other pathologies), intraoperative CSF leakage was observed in 27.4% of 197 cases : 14.7% Grade 1, 4.6% Grade 2a, 3.0% Grade 2b, and 5.1% Grade 3. Postoperative CSF leakage was observed in none of the cases. Septal bone buttress was used for Grade 1 to 3 leakages instead of any other foreign materials. Pedicled nasoseptal flap was used for Grades 2b and 3 leakages. Unused septal bones and nasoseptal flaps were repositioned. Conclusion : Modified classification of intraoperative CSF leaks and tailored repair technique in a multilayered fashion using an en-bloc harvested septal bone and vascularized nasoseptal flaps is an effective and reliable method for the prevention of postoperative CSF leaks.

Background The umbilicus makes an important contribution to the natural appearance of the abdomen. To date, studies on its position in Korean women are lacking, and no standards have been established. The purpose of this study was to investigate the position of umbilicus in Korean women and to review changes in its position after ipsilateral pedicled rectus abdominis musculocutaneous (IP-RAM) flap. Methods This research consisted of two studies. In first study, 100 females who visited the emergency department with gastroenteritis between 2007 and 2011 were included. In second study, 40 women who underwent IP-RAM flap in the same period were included. Using abdominal computed tomography, we measured the distance between xiphoid process and umbilicus, represented by value a, and the distance between umbilicus and symphysis pubis, represented by value b. Thus, the location of the umbilicus was represented by the ratio a/b. The data were analyzed using Pearson correlation test and paired t-test. Results In study 1, the mean value of a/b was 1.07. Pearson correlation test revealed a significant correlation between age and a/b. In study 2, the mean value of a/b was 1.16 in preoperative measurements and 1.01 in postoperative measurements. The paired t-test showed a significant difference between preoperative and postoperative measurements, indicating cephalic migration of the umbilicus after surgery. Conclusions The natural position of the umbilicus showed caudal migration with aging. Additionally, in a comparison of preoperative and postoperative measurements in patients who underwent IP-RAM flap, cephalic migration of the umbilicus was observed after surgery.

Persistent bronchopleural fistula (BPF) still presents a troublesome therapeutic challenge and demands an aggressive approach when conventional measures fail. A 50-year-old man had a rigtlt pneumonectomy for far-advanced pulmonary tuberculosis with the development of postopneumonectomy empyema and BPF 1 month postoperatively in October 1 81. The condition was managed with BPF closure and the Clagett procedure, which failed with the recurrence of BPF and empyema, followed by a spontaneous open window at about 1 year port:operatively. The BPF, which had been aggravated to a large size, was managed by the closure and obliteration of the empyema cavity using a Pectoralis-skin pedicled flap 13 years postoper atively on Jul, 1994. The BPF was controlled by the procedure, and the patient, with improved respiratory symptom, was discharged 43 days postoperatively. We conclude that the use of myocutaneous flap Is an effective procedure for the closure of a large BPF. The surgical technique of the pedicled flap operation is described and the case is reported.

Background In cases of total knee arthroplasty (TKA) threatened by potential hardware exposure, flap-based reconstruction is indicated to provide durable coverage. Historically, muscle flaps were favored as they provide vascular tissue to an infected wound bed. However, data comparing the performance of muscle versus fasciocutaneous flaps are limited and reflect a lack of consensus regarding the optimal management of these wounds. The aim of this study was to compare the outcomes of muscle versus fasciocutaneous flaps following the salvage of compromised TKA. Methods A systematic search and meta-analysis were performed to identify patients with TKA who underwent either pedicled muscle or fasciocutaneous flap coverage of periprosthetic knee defects. Studies evaluating implant/limb salvage rates, ambulatory function, complications, and donor-site morbidity were included in the comparative analysis. Results A total of 18 articles, corresponding to 172 flaps (119 muscle flaps and 53 fasciocutaneous flaps) were reviewed. Rates of implant salvage (88.8% vs. 90.1%, P=0.05) and limb salvage (89.8% vs. 100%, P=0.14) were comparable in each cohort. While overall complication rates were similar (47.3% vs. 44%, P=0.78), the rates of persistent infection (16.4% vs. 0%, P=0.14) and recurrent infection (9.1% vs. 4%, P=0.94) tended to be higher in the muscle flap cohort. Notably, functional outcomes and ambulation rates were sparingly reported. Conclusions Rates of limb and prosthetic salvage were comparable following muscle or fasciocutaneous flap coverage of compromised TKA. The functional morbidity associated with muscle flap harvest, however, may support the use of fasciocutaneous flaps for coverage of these defects, particularly in young patients and/or high-performance athletes.

Pulmonary thromboembolism is often clinically silent and difficult to diagnose, and can be fatal to patients with belated treatment. This complication is seen in patients who underwent TRAM breast reconstruction. Multiple factors are involved in this disease such as the presence of malignancy itself, major surgery and therapy-related interventions. TRAM surgery is a lengthy procedure involving mastectomy, flap surgery and abdominoplasty. The purpose of this study is to evaluate the incidence and the correlation between presurgical risk factors(BMI and age) of symptomatic pulmonary thromboembolism after TRAM surgery and the incidence. From July 2001 to March 2005 a total of 384 pedicled TRAM reconstruction of breast was performed in 382 patients at Asan Medical Center. The average of Body mass index was $21.9kg/m^2$ and mean age of the patients was 37.9 years old. We diagnosed symptomatic pulmonary thromboembolism using ventilation/perfusion lung scan and pulmonary embolism computed tomography. Incidence of in-hospital symptomatic pulmonary thromboembolism was 1.3%. BMI and age showed no significant statistical relationship to pulmonary thromboembolism. But the incidence of symptomatic pulmonary thromboembolism in obese patients (BMI > 25) was 3.75%. According to the guideline of the 7th American College of Chest Physicians Consensus Conference on Antithrombotic and Thrombolytic Therapy, the incidence of 3.75% was classified as high risk group. The prevention of pulmonary thromboembolism should be considered in cases of obese patients with low molecular weight heparin(BMI > 25).

Background The evaluation of a breast after breast reconstruction depends on a surgeon's subjective criteria. We used computed tomography (CT) scans to obtain an objective evaluation of the postoperative results by measuring the breast volume of patients who had undergone breast reconstruction using pedicled transverse rectus abdominis myocutaneous (TRAM) flaps. This research will help in the objective postoperative evaluation of reconstructed breasts, and also in the preoperative flap size designs. Methods A total of 27 patients underwent breast reconstruction using pedicled TRAM flaps after mastectomy from September 2007 to July 2010. Of these, 10 patients who were followed up and underwent CT scans 2 or more times during the follow-up period were included in this study. We evaluated the change in breast volume over time using CT scans, and the interval breast volume change between CT scans. Results All of the 10 patients' reconstructed breasts showed a volume decrease over time. The breast volume changes in the intervals between CT scans were as follows: 5.65% decrease between the first CT and second CT scan, 2.3% decrease between the second CT and third CT scan, (statistically significant) and 1.89% decrease between the third CT and forth CT scan. (not statistically significant). Conclusions This research shows the possibility of objectively evaluating the postoperative breast volume changes. The findings will be helpful in designing the size of TRAM flaps to use on defects after mastectomy. Based on these results, we should also closely observe the reconstructed breast volume for at least 2 years.

Purpose: The transverse rectus abdominis musculocutaneous(TRAM) flap is the most commonly used autogenous tissue flap for breast reconstruction. Postoperatively, partial flap loss or fat necrosis are relatively common and it may result in a smaller breast volume with marked contour irregularities. These defects are not easy to reconstruct with local tissue rearrangement or with breast implants. The current authors present the results of 2 patients who underwent Latissimus dorsi(LD) flap reconstruction to correct partial flap or fat necrosis that developed after TRAM flap breast reconstruction. Method: Case1: A 50 - year - old woman with left breast cancer visited for breast reconstruction after radical mastectomy. Initially, breast reconstruction with pedicled TRAM was performed. Postoperatively partial flap necrosis was developed. Secondary breast reconstruction using LD flap was done. Case2: A 51 - year - old woman with left breast cancer visited for breast reconstruction after radical mastectomy. Initially, breast reconstruction with pedicled TRAM was performed. Postoperatively fat necrosis was developed. Secondary breast reconstruction using LD flap was done. Results: Secondary breast reconstruction using LD flap survived completely and produce successful reconstruction. There was no significant complication in both patients. Conclusion: LD flap provides sufficient, vascularized skin and soft tissue. The flap can be molded easily to replace deficient tissue in all areas of the breast. These attributes make it an ideal candidate for salvage of the partially failed TRAM flap breast reconstructio.

The buccal fat pad is specialized fat tissue located anterior to the masseter muscle and deep to the buccinator muscle. Possessing a central body and four processes it provides separation allowing gliding motion between muscles, protects the neurovascular bundles from injuries, and maintains facial convexity. Because of its many advantageous functions, the use of the buccal fat pad during oral and maxillofacial procedures is promoted for the reconstruction of defects secondary to tumor resection, and those defects resulting from oroantral fistula caused by dento-alveolar surgery or trauma. We used the pedicled buccal fat pad in the reconstruction of intraoral defects such as oroantral fistula, maxillary posterior bone loss, or defects resulting from tumor resection. Epithelization of the fat tissue began 1 week after the surgery and demonstrated stable healing without complications over a long-term period. Thus, we highly recommend the use of this procedure.

Latissimus dorsi myocutaneous flap is useful for the breast reconstruction, chest wall coverage, free flap transfer, and head and neck area reconstruction, especially in large defect. We have had some experience of 5-pedicled and 1-free latissimus dorsi myocutaneous flap in head and neck area and found many advantages and some problems. The conclusions were as follows : 1. Potentially large flap size enabled us agressive tumor resection and reconstruction. 2. Speedy and easy flap elevation and long vascular pedicles reduced operation time and flap failure. 3. Due to fewer complication and functional loss of doner site, pedicled latissimus dorsi flap was a good choice for large head and neck reconstruction. 4. Because of flap bulkness, thin and small defect was not appropriate for reconstruction.
