Donor-Site Morbidity After DIEAP Flap Breast Reconstruction-A 2-Year Postoperative Computed Tomography Comparison.

ABSTRACT: The study was undertaken to provide a more complete picture of donor-site morbidity following the deep inferior epigastric artery perforator (DIEAP) flap harvest in breast reconstruction. Most studies evaluating this subject have been performed using ultrasonography. Computed tomography (CT) might provide valuable information.

Methods

In 14 patients who were reconstructed with a DIEAP flap, donor-site morbidity was assessed by comparing routine preoperative CT abdomen with CT abdomen performed 2 years postoperatively. The anteroposterior diameter and transverse diameter (TD) of the rectus muscle were measured bilaterally within 4 standardized zones. Diastasis recti abdominis (DRA) was measured in the same zones. The abdominal wall was assessed for hernias, bulging, and seromas.

Results

The operated rectus muscle had a significantly increased anteroposterior diameter in 2 zones and decreased TD in 1 zone compared with preoperative measurements. Comparing the operated and nonoperated rectus muscles, the former had a significantly decreased TD in 1 zone. Supraumbilical DRA was significantly decreased with surgery, whereas infraumbilical DRA was significantly increased. No new hernias or bulging were found. Two patients had seroma formation in the abdominal wall.

Conclusions

Symmetry of the 2 hemiabdomens is well preserved after DIEAP flap harvest; however, significant changes to the rectus muscles and DRA were observed. Hernia formation does not seem to be a postoperative complication of importance. The study indicates that DIEAP flaps result in limited donor-site morbidity, which for most patients does not outweigh the benefits of free perforator flap breast reconstruction.

Project description:BackgroundThe predominant method for Manske type IIIB and IV thumb hypoplasia is pollicization. However, for those who are not willing to sacrifice the index finger, a method that could reconstruct a functionally capable and aesthetically acceptable thumb remains desirable. This study aimed to investigate and assess the functional and radiographic outcomes of utilizing a reversed vascularized second metatarsal composite flap for thumb reconstruction as a new alternative.MethodsFrom May 2014 to January 2017, 15 patients with Manske type IIIB or IV thumb hypoplasia who were admitted to the Department of Hand Surgery, Beijing Jishuitan Hospital were included in this study. An osteocutaneous flap containing a section of second metatarsal and its distal head was transferred in reversed position to reconstruct carpometacarpal joint. The donor site was reconstructed by a split half of the third metatarsal. Various functional reconstructions were commenced at second stage. The reconstructed thumbs were evaluated using the Kapandji score, pinch force, and the capacities of performing daily activities through a detailed questionnaire.ResultsAmong these 15 patients (seven type IIIB and eight type IV), there were ten boys and five girls with median age of 4.2 years (range: 2.0-7.0 years). There were seven right, three left, and five bilateral thumbs for whom only the right thumb received surgery. There were 14 metatarsal flaps survived (14/15). With an average follow-up of 19.2 months, the reconstructed thumbs had acceptable functional and aesthetic outcomes and the donor foot presented in decent appearance without signs of impaired function. All 15 children have improved the Kapandji score (from 0 to an average of 6.7), pinch force (from 0 to an average of 1.5 kg), with ability of grip and pen holding. X-ray indicated continuous bone growth. Patients and parents had good acceptance of the new thumb.ConclusionsReconstruction of an unstable hypoplastic thumb (Manske type IIIB and IV) with use of a vascularized metatarsal is an effective strategy. It offers an alternative solution for parents insisting on saving the thumb.

Project description:ImportanceParamedian forehead flaps are commonly used to reconstruct facial defects caused by skin cancers. Data are lacking on the complications from this procedure, postoperative outcomes, and association of cancer diagnosis with rate of deep venous thrombosis (DVT).ObjectivesThe primary objective was to determine complication rates after paramedian forehead flap reconstruction for defects resulting from resection of facial cancers; and the secondary objective was to determine patient factors and complications that are associated with readmission.Design, setting, and participantsRetrospective cohort study of patients who underwent paramedian forehead flap reconstruction for skin cancer reconstruction from January 1, 2007, through December 31, 2013. Data analysis took place between October 1, 2017, and June 1, 2018.Main outcomes and measuresComplication rates including DVT, emergency department visits, and hospital readmissions.ResultsA total of 2175 patient were included in this study; mean (SD) age, 70.3 (13.4) years; 1153 (53.5%) were men. Postoperative DVT occurred in 10 or fewer patients (≤0.5%); postoperative bleeding in 30 (1.4%), and postoperative infection in 63 (2.9%). Most patients went home on the day of surgery (89.6%; n = 1949), while 10.4% stayed one or more days in the hospital (n = 226). Overnight admission was associated with tobacco use (odds ratio [OR], 1.65; 95% CI, 1.11-2.44), hypothyroidism (OR, 1.93; 95% CI, 1.10-3.39), hypertension (OR, 1.82; 95% CI, 1.29-2.57), ear cartilage graft (OR, 2.20; 95% CI, 1.51-3.21), and adjacent tissue transfer (OR, 1.88; 95% CI, 1.33-2.67). Risk factors strongly associated with immediate return to the emergency department or readmission within 48 hours of surgery included postoperative bleeding (OR, 13.05; 95% CI, 4.24-40.16), neurologic disorder (OR, 4.11; 95% CI, 1.12-15.09), and alcohol use (OR, 7.70; 95% CI, 1.55-38.21).Conclusions and relevanceIn this study, the most common complication of paramedian forehead flap reconstruction was infection. Risk factors for readmission included development of postoperative bleeding, having a neurologic disorder, and alcohol use. Deep venous thrombosis was a rare complication. Because bleeding is a more common complication in this patient population, discretion should be used when deciding to administer anticoagulation medication to low- to medium-risk patients prior to surgery.Level of evidenceNA.

Project description:Autologous reconstruction techniques for breast reconstruction have significantly evolved in the last few decades in Europe. In the search of reducing the donor site morbidity, surgeons explored the possibilities to preserve the rectus muscle and its function, and a transition to deep inferior epigastric perforator (DIEP) flaps was started in the nineties. Throughout the years, and especially in the last decade, we have increasingly implemented aesthetic refinements for donor site handling in DIEP flap breast reconstruction. In our practice, autologous breast reconstruction provides an opportunity to effectively remodel the donor site, minimising functional morbidity, and maximising aesthetic satisfaction. To achieve this, careful patient selection, pre-operative preparation, meticulous intra-operative dissection, and a clear post-operative protocol are essential. The main goal in autologous breast reconstruction, and its biggest advantage, is to offer the patient a natural look and feel of the reconstructed breast. A second goal is to minimize the number of procedures needed to reach the desired breast shape, size, and volume. In most patients, the number of operations ranges between one and three. The third main goal is to minimize the donor site morbidity, both functionally and aesthetically. Functionally, this implies preserving as much of the rectus abdominis muscle as possible, limiting the fascia incision, preserving the motor branches to the muscle, ensuring an adequate fascial closure, and repairing the rectus diastasis is present. Aesthetically, we aim to have a low position of the scar, an aesthetically pleasing location of the umbilicus, and limited or no lateral skin excess or so called "dogears". In this clinical practice review article, we provide an overview of current autologous reconstruction methods, with a focus on minimising donor site morbidity and enhancing the aesthetic result of the donor site. We discuss key concepts in autologous reconstruction and provide surgical pearls for performing the procedure effectively with optimal reconstructive and aesthetic result.

Project description:ObjectiveChest computed tomography (CT) imaging is being increasingly used for potential lung donor assessment. However, the efficacy of CT imaging in this setting remains unknown. We hypothesize that chest CT imaging independently affects the decision-making process in donor lung utilization.MethodsWe conducted a retrospective cohort study of all adult donation after brain death donors managed through our local organ procurement organization from June 2011 to November 2016. An experienced thoracic radiologist independently reviewed donor chest CT and chest x-ray images in a blinded, standardized manner to determine the presence of structural lung disease (eg, emphysema, interstitial lung disease [ILD]) and acute abnormalities (eg, traumatic lung injury [TLI]). Distinct models of lung utilization were fit to groups with initial partial pressure of oxygen (iPaO2) ≤300 mm Hg (suboptimal) and iPaO2 >300 mm Hg (optimal).ResultsThe organ procurement organization managed 753 donors during the study period, with a lung utilization rate ([lung donors/all organ donors] × 100) of 36.5% (275 of 753). Four hundred forty-five (59.1%) donors received chest CT imaging, revealing emphysema (13.7%), ILD (2.5%), and TLI (7.2%). In univariate analysis, findings of TLI (odds ratio [OR], 2.23; 95% confidence interval [CI], 1.08-4.61) were positively associated with lung utilization, whereas findings of emphysema (OR, 0.18; CI, 0.08-0.40) were negatively associated with utilization. In multivariate analysis, CT findings of emphysema (OR, 0.21; CI 0.08-0.54) remained negatively associated with utilization. No potential donors with CT findings of ILD became lung donors. After controlling for chest x-ray findings, chest CT imaging findings of structural lung disease remained negatively associated with utilization (P = .0001). Lung utilization rate in the suboptimal and optimal iPaO2 populations was 35.1% and 41.4%, respectively, and CT findings of emphysema had a significant association with nonutilization in both groups.ConclusionsIn the evaluation of potential lung donors, chest CT imaging findings of structural lung disease, such as emphysema and ILD, have a significant negative association with lung utilization. Our findings suggest that chest CT imaging might be an important adjunct to conventional lung donor assessment criteria.

Project description:ObjectiveThis study aims to evaluate the effects of topical hyaluronic acid (HA), hypochlorous acid (HOCl), and flurbiprofen on postoperative morbidity of palatal donor sites after free gingival graft (FGG) surgery.Materials and methodsSixty patients requiring FGG were randomly assigned into four groups: control, HA gel (600 mg/100 g high molecular weight hyaluronic acid), HOCl spray (170-200 ppm, ph7.1), flurbiprofen spray (0.075gr flurbiprofen). Topical agents were applied for 14 days, according to groups. Patients were followed for 28 days. Palatal healing was assessed with the Laundry wound healing index (WHI). Complete epithelization (CE) was evaluated with photographs and H2O2 bubbling. Pain, burning sensation, chewing efficacy, and tissue color match (CM) were evaluated using a visual analog scale (VAS). Postoperative analgesic consumption and delayed bleeding (DB) were also recorded.ResultsHA provided better WHI values on the 7th, 14th, and 21st days compared to the other groups, respectively (p < 0.05). CE was formed on the 21st day in the HA group but on the 28th day in the other groups. HOCl and flurbiprofen groups were not different from the control group or each other in terms of WHI. HOCl had the lowest VAS scores of all time periods. DB was not observed in any group. Significantly fewer analgesics were taken in the topical agent-applied groups compared to the control group.ConclusionsHA exhibits a positive impact on the epithelization of palatal wound healing and color matching. HOCl and flurbiprofen provided less pain; however, they might have negative effects on palatal wound healing.Clinical relevanceAs a result of obtaining free gingival grafts from palatal tissue for mucogingival surgical procedures, secondary wound healing of the donor area occurs. This wound in the palatal region can cause discomfort and pain every time patients use their mouths. The use of HA can reduce postoperative complications by accelerating wound healing and reducing pain. The topical use of flurbiprofen and HOCl can reduce patients' pain.
