Project description:BackgroundBreast reconstruction using the latissimus dorsi (LD) flap is one of the most popular and common breast reconstruction techniques among Asian patients. There are increasing numbers of cases wherein breasts need to be reconstructed to moderate to large sizes among the Asian population. Most reconstructive surgeons use abdominal-based flaps-such as the deep inferior epigastric perforator and transverse rectus abdominis myocutaneous flap, or LD flap with an implant-to supplement the volume. Here, we compare the usefulness of the boomerang LD (bLD) flap-a technique developed by modifying the design of the conventional extended LD flap-with that of the LD flap with implant (LDi).MethodsThis was a prospective cohort study including patients with breast cancer aged between 25 and 60 years who underwent unilateral total or skin/nipple-sparing mastectomy, or postmastectomy. The exclusion criteria were advanced breast cancer (stages 3 and 4); a history of cognitive impairment affecting ability to complete the self-reported questionnaire; a history of neurologic or musculoskeletal disorder; and a history of alcohol or drug abuse. Statistical analysis was performed, and correlations between the two technique types were analyzed [including age, body mass index, preoperative breast volume, operation time, flap elevation time, admission duration, adjuvant treatment (radiotherapy, chemotherapy), drain indwelling duration, and drain total sum volume].ResultsIn total, 85 patients who underwent immediate breast construction through the LDi group (n=63) or bLD group (n=25) techniques after total mastectomy between January 2015 and June 2022 were analyzed (mean age: LDi group, 46±7.7 years; bLD group, 45.6±7.8 years). We observed that the flap weight, operative time, mean admission duration, and drain indwelling duration were statistically significantly different in the bLD group (P<0.05). Body mass index, preoperative breast volume, specimen weight, flap elevation time, and drain total time were comparable between groups.ConclusionsBreast reconstruction using the bLD flap was found to be a suitable alternative technique for patients who desire an autologous tissue transfer (rather than an implant) but are contraindicated for abdominal-based flaps and do not mind long postoperative scars.

Project description:Robot-assisted surgery is evolving to incorporate a higher number of minimally invasive techniques. There is a growing interest in robotic breast reconstruction that uses autologous tissue. Since a traditional latissimus dorsi (LD) flap leads to a long donor scar, which can be an unpleasant burden to patients, there have been many attempts to decrease the scar length using minimally invasive approaches. This study presents the case of a patient who underwent a robot-assisted nipple-sparing mastectomy followed by immediate breast reconstruction with an LD flap using a single-port robotic surgery system. With the assistance of a single-port robot, a simple docking process using a short and less visible incision is possible. Compared to multiport surgery systems, single-port robots can reduce the possibility of collision between robotic arms and provide a clear view of the medial border of the LD where the curvature of the back restricts the visual field. We recommend the use of single-port robots as a minimally invasive approach for harvesting LD flaps.

Project description:BACKGROUND:Using the Latissimus dorsi (LD) muscle flap is one of the popular surgical technique for breast reconstruction. However, usually, long postoperative scar was remained on donor site which does not have disease. The authors applied the endoscopy-assisted surgery to harvest the LD muscle flap for breast reconstruction. METHODS:From July 2018 to July 2019, five consecutive patients with breast cancer underwent partial mastectomy with endoscopy-assisted LD muscle flap reconstruction. The clinic-pathologic factors were analyzed and the cosmetic outcomes were assessed with breast shape, scarring of breast and back. A 4-6?cm of lateral incision (donor site scar) was designed and LD muscle was harvested under endoscopic surgery without gas inflation. And the harvested LD muscle was inserted for partial breast reconstruction after the cancer surgery was done. RESULTS:Mean operative time was 116.4?min (range, 92-134) and there was no major postoperative complication. The satisfactory degree of cosmetic outcomes were shown better in patient's survey than that of surgeon's. CONCLUSIONS:The endoscopy-assisted LD muscle flap harvesting would be useful technique to eliminate a large donor site incision in partial breast reconstruction.

Project description:Background:This study aimed to evaluate the volume reduction of latissimus dorsi muscle in patients who underwent immediate breast reconstruction using extended latissimus dorsi musculocutaneous (eLDMC) flap with implant after skin/nipple sparing mastectomy (SSM/NSM) and postoperative chemotherapy (POCTx). Methods:We retrospectively reviewed clinical records of 19 patients who underwent this surgery with POCTx, and checked chest computer tomography (CT) at 7-10 days after surgery and 6-14 months after the end of chemotherapy, from May 2015 to October 2016. The motor nerve to latissimus dorsi muscle was severed in all patient. One plastic surgeon intervened and the follow up period was at least 18 months. Author obtained the area of latissimus dorsi muscle using the Picture Archiving and Communication System (PACS) in the axial view of the chest CT and it was verified by the experienced radiologist. The statistical test was performed (P<0.05). Results:There was statistically decrease in latissimus dorsi muscle volume after the end of POCTx, range from 51.5-77.5%, average volume decrease was 62%, compared with latissimus dorsi muscle volume of the CT taken 7-10 days postoperatively (P<0.05). After a minimum follow-up period of 18 months, 14 of the 19 cases were satisfactory for both the surgeon and the patient. In 4 patients, breast volume was symmetrical when wearing bra, but the outline of the 90 cc implant was unfavorable. One patient had a smaller size of reconstructed breast than the other. Conclusions:The size of the implant should be determined considering that average latissimus dorsi muscle reduction is 62%. Especially, the size of the implant should be chosen carefully if latissimus dorsi muscle is thick or it occupies a large portion of the entire flap.

Project description:Background A novel endoscopic-assisted technique (NET) was created by our team for nipple-sparing mastectomy (NSM) and latissimus dorsi muscle flap (LDMF) reconstruction that enables the procedure to be conducted through a single axillary incision. The authors hypothesized that the NET has the advantages of the traditional ET (TET) and a reduced operation time. The purpose of this study is to compare the advantages and disadvantages of NET, TET and open surgery. Methods A retrospective cohort study was performed on patients who underwent LDMF reconstruction after NSM using open surgery, the TET, or the NET between January 2013 and June 2021. The following outcomes were compared: the operation time, size of the LDMF, the complication rate, hospital length of stay, hospital costs, aesthetic results (the BREAST-Q questionnaire), and quality of life (QoL). The BREAST-Q questionnaire and QoL were underwent preoperatively and 1, 3, and 12 months postoperatively. Results A total of 17 ETs (comprising 10 NETs and 7 TETs) and 28 open surgery procedures were identified and analyzed, the baseline characteristics were comparable in terms of age, body mass index (BMI), tumor location, cup size, and disease stage of the three groups. The mean operation time of the NET group (395.8±176.0 min) in the exploration stage was shorter than that of the TET group (531.6±69.6 min) and equivalent to that of the open surgery group (400.9±67.3 min). The overall postoperative complication rates of the ET and open surgery groups were 35.3% and 60.7%, respectively (P=0.09). The aesthetic results in relation to patients’ satisfaction with their breasts (P=0.001) and backs (P=0.001) were better in the ET group than the open surgery group beginning at 1 month postoperatively. The ET group had better psychosocial well-being beginning at 1 month postoperatively (P=0.002) and sexual well-being beginning at 3 months postoperatively (P<0.001) than the open surgery group. Conclusions LDMF reconstruction after NSM using the ET is associated with lower complication rates, good aesthetic results, and a better QoL than open surgery procedures. The NET is a promising approach, a more convenient procedure, and has a shorter surgery time than TET, however, this conclusion needs to be further validated by randomized clinical trial (RCT) research with a larger sample size.

Project description:OBJECTIVE:To study the value of 3D visualization technique in breast-preserving surgery for breast cancer with immediate breast reconstruction using laparoscopically harvested pedicled latissimus dorsi muscle flap. METHODS:From January, 2015 to May, 2016, 30 patients with breast cancer underwent breast-preserving surgery with immediate breast reconstruction using pedicled latissimus dorsi muscle flap. The CT data of the arterial phase and venous phase were collected preoperatively and imported into the self-developed medical image 3D visualization system for image segmentation and 3D reconstruction. The 3D models were imported into the simulation surgery platform for virtual surgery to prepare for subsequent surgeries. The cosmetic outcomes of the patients were evaluated 6 months after the surgery. Another 18 patients with breast cancer who underwent laparoscopic latissimus dorsi muscle breast reconstruction without using 3D visualization technique from January to December, 2014 served as the control group. The data of the operative time, intraoperative blood loss and postoperative appearance of the breasts were analyzed. RESULTS:The reconstructed 3D model clearly displayed the anatomical structures of the breast, armpit, latissimus dorsi muscle and vessels and their anatomical relationship in all the 30 cases. Immediate breast reconstruction was performed successfully in all the cases with median operation time of 226 min (range, 210 to 420 min), a median blood loss of 95 mL (range, 73 to 132 mL). Evaluation of the appearance of the breast showed excellent results in 22 cases, good appearance in 6 cases and acceptable appearance in 2 cases. In the control group, the median operation time was 283 min (range, 256 to 313 min) and the median blood loss was 107 mL (range, 79 to 147 mL) with excellent appearance of the breasts in 10 cases, good appearance in 4 cases and acceptable appearance in 4 cases. CONCLUSION:3D reconstruction technique can clearly display the morphology of the latissimus dorsi and the thoracic dorsal artery, allows calculation of the volume of the breast and the latissimus dorsi, and helps in defining the scope of resection of the latissimus dorsi to avoid injuries of the pedicled vessels. This technique also helps to shorten the operation time, reduce intraoperative bleeding, and improve the appearance of the reconstructed breast using pedicled latissimus dorsi muscle flap.

Project description:The latissimus dorsi flap (LDF) has gained popularity given its versatile nature and broad applicability in breast reconstruction. Its resurgence has been attributed to its ability to be enhanced using implant or high-volume fat grafting, rendering it a primary option for selected patients. The aim of this review is to tackle current indications and subjects of controversy regarding use of complete-autologous and implant-enhanced LDF in breast reconstruction. Also, a case-series showcasing the authors' experience with this versatile reconstructive option is presented. A search across Web of Science and PubMed MEDLINE from inception through January 3, 2023, was conducted. Articles reporting postoperative outcomes of autologous breast reconstruction with LDF were included. Regarding the case series, electronic medical records of patients who underwent total mastectomy and autologous breast reconstruction with LDF from January 2011 to December 2021 were retrospectively reviewed. Data on demographic and oncologic characteristics, and surgical characteristics and outcomes were extracted. Our review suggests that LDF is suitable for patients who lack alternative donor site, have a history of abdominoplasty or no access to microsurgery, smokers or obese. Latissimus dorsi (LD) harvesting has almost complete shoulder function recovery in the long-term. Thoracodorsal nerve division does not cause volume loss or animation deformity. Multisite multilayer fat grafting, beveling the edges of the skin paddle and fat, folding the LD muscle and plicating the paddle allow adequate projection and contour achievement. Our case-series included 234 reconstructions. Almost half of the patients had immediate fat transfer during reconstruction (51.3%). The rate of recipient site hematoma was 3.0%, seroma was 7.7%, wound disruption 32.1%, wound disruption events requiring unplanned procedures was 13.7%, and surgical site infection (SSI) was 12.4%. The LDF is reliable and safe for immediate or delayed breast reconstruction or salvage after reconstruction failure. Its versatility, reliable anatomy, easy dissection, and relative low complication rate have revived this modality as valuable opportunity for breast reconstruction in this era.

Project description:BackgroundFull-thickness burns of the anterior chest wall during childhood are a devastating problem that results in significant distortion of the developing breast. This deformed burnt breast represents a serious aesthetic problem, and can lead to functional impairment as well as severe emotional trauma for patients.MethodsPatients with postburn scarring affecting the lower pole of the breast were included. Only patients with small to medium-sized breasts were targeted. The lower breast pole was reconstructed using muscle-sparing latissimus dorsi flap. All patients had been subjectively assessed, including overall patient satisfaction regarding breast aesthetics, donor site morbidity, and functional deficits of latissimus dorsi muscle, 3 months postoperatively.ResultsSix patients (seven breasts) were included in this study. Muscle-sparing latissimus dorsi flap was used to reconstruct lower breast pole in all patients. A horizontally-oriented skin paddle was used in five patients, whereas a vertically oriented skin paddle was used in one patient. Average patient satisfaction was 9.1 (SD 0.6) for the reconstructed lower breast pole. For the donor site, average overall satisfaction was 9.1 (SD 0.8). Latissimus dorsi muscle function was objectively confirmed in 90% of cases after 3 months postoperatively. Patients had an average score of 3.9 (SD 0.4) for the activity score as well.ConclusionsThe muscle-sparing latissimus dorsi flap is a good reconstructive tool for lower breast pole in postburn breast reconstruction. It has a reliable versatile skin paddle that can resurface the whole lower breast pole, while avoiding many of the latissimus flap morbidities.

Project description:BackgroundWe conducted a prospective cohort study to evaluate effective techniques for breast reconstruction after partial mastectomy due to breast cancer. Determining the method of reconstruction is often difficult as it depends on the location of the cancer and the amount of tissue excised.. Here, we present a new technique, using the vertical latissimus dorsi (LD) flap, that can be used in all partial mastectomies and can almost conceal scarring. We also compared these results to those of the mini LD flap.MethodsWe analyzed the data of a total of 50 and 47 patients, who underwent breast reconstruction with the mini LD flap and the vertical LD flap, respectively. Immediately after tumor excision, breast reconstruction was initiated. The skin flap for vertical LD was designed in a planarian shape, such that it may be hidden as much as possible and minimize bulging during closure, and the LD muscle flap was designed with a sufficient distance in the inferior direction.ResultsOur finding showed that the vertical LD flap group required significantly less total operation time than the mini LD flap group. While the mini-LD flap resulted in a scar that was difficult to conceal, the donor site scar of the vertical LD flap could not be seen easily, and no scar was visible on the back.ConclusionsThe vertical LD flap is useful for partial breast reconstruction, in all breast regions requires a rather small volume of the flap. Moreover, recovery was relatively fast with high patient satisfaction.
