The Impact of Increased Body Mass Index on Patient Outcomes and Complications in Microsurgical Lower Extremity Reconstruction.

BACKGROUND: Elevated body mass index (BMI) is a known perioperative risk factor for complications such as delayed wound healing and infection. However, there is a gap in understanding how elevated BMI impacts outcomes after posttraumatic lower extremity (LE) microvascular reconstruction. METHODS: A retrospective review was performed at a level 1 trauma center between 2007 and 2022 of patients who underwent posttraumatic microvascular LE reconstruction. Demographics, flap/wound details, complications, and outcomes were recorded. Patients were stratified into BMI Center for Disease Control categories. RESULTS: A total of 398 patients were included with an average BMI of 28.2 ± 5.8. Nearly half (45%) of LE defects were located in the distal third of the leg, 27.5% in the middle third, and 34.4% in the proximal third. Most reconstructions utilized muscle-containing flaps (74.4%) compared with fasciocutaneous flaps (16.8%). Surgical approaches included free flaps (47.6%) and local flaps (52.5%). Class III obese patients were significantly more likely to be nonambulatory than nonobese patients (OR: 4.10, 95% CI 1.10-15.2, p = 0.035). At final follow-up, 30.1% of patients with Class III obesity were ambulatory, requiring either wheelchairs (42.3%) or assistance devices (26.9%). There were no significant differences in complication rates based on obesity status (0.704). The average follow-up time for the entire cohort was 5.8 years. CONCLUSIONS: BMI is critical for patient care and surgical decision-making in LE reconstruction. Further research is warranted to optimize outcomes for higher BMI patients, thereby potentially reducing the burden of postoperative complications and enhancing overall patient recovery.

Mid-term outcomes of sartorius flap reconstruction in groin infection following vascular procedures or intravenous drug injections.

BACKGROUND: In this study, the early and mid-term outcomes of sartorius flap reconstruction after the development of a prior groin infection were investigated. METHODS: From January 2017 until June 2023, 44 patients from 2 centers in Italy underwent sartorius flap reconstruction after the development of a prior groin infection. Thirty-day outcome measures including major morbidity, amputation-free survival, and mortality were assessed. At 2-year follow-up, estimated outcomes of freedom from hemorrhagic complications, freedom from recurrent infection, freedom from reintervention, and amputation-free survival were analyzed using Kaplan-Meier curves. RESULTS: In 35 cases (79.5%) a previous vascular procedure was performed, whilst in the remaining 9 cases (20.5%) the patient was an intravenous drug abuser. Thirty-day mortality and major amputation rates were 4.5%, and 2.3%, respectively. Overall 30-day wound healing rate was 56.8% (25 cases). The overall median duration of follow-up was 12 months (IQR 4-24). Complete wound healing was obtained in 36 cases (81.8%) after a median period of 1 month (IQR 1-3). The 2-year Kaplan-Meier estimates of freedom from hemorrhagic complications, freedom from recurrent infection, freedom from reintervention, and amputation-free survival were 82.1%, 70%, 71.9%, and 97.7%, respectively. Multivariate analysis confirmed the association of female sex with recurrent infection (HR 3.4, P=.05). CONCLUSIONS: Sartorius flap reconstruction after the development of a prior groin infection following vascular procedures or intravenous drug injections yielded acceptable mid-term outcomes in terms of freedom from hemorrhagic complications, and freedom from recurrent infection. Female sex seemed to affect the rate of recurrent infection.

Postinflammatory Hyperpigmentation Following Mohs Micrographic Surgery: An Observational Study.

IMPORTANCE: Functional and cosmetic outcomes following Mohs micrographic surgery (MMS) are poorly studied in individuals with skin of color (SOC). Postinflammatory hyperpigmentation (PIH) may be long-lasting and highly distressing. SOC individuals are particularly susceptible to PIH following procedures.  Objective: To characterize factors that contribute to the development of PIH following MMS in SOC. DESIGN: This retrospective study included 72 SOC individuals with 83 cases of keratinocyte carcinoma treated with MMS between August 2020 and August 2021 at a single medical center in the Bronx, New York. RESULTS: Postinflammatory hyperpigmentation following Mohs micrographic surgery was more common in Fitzpatrick skin types (FST) IV to V (48.0%) compared to FST I to III (18.2%; P=0.006). Grafts and granulation resulted in higher rates of PIH compared to linear repairs and flaps (87.5% vs 30.7%; P=0.003). Cases with postoperative complications resulted in higher rates of PIH compared to cases without (81.8% vs 29.2%; P=0.001). In a subset analysis of linear repairs, polyglactin 910 as a subcutaneous suture produced a higher rate of PIH compared to poliglecaprone 25 (46.2% vs 7.1%; P=0.015).  Conclusions and Relevance: Individuals with SOC (FST IV to V) are more likely to develop PIH following MMS. Grafts and granulation lead to PIH more often than linear repairs and flaps. Postoperative complications significantly increase the risk of PIH. Surgeons should consider these risk factors during surgical planning in an effort to mitigate PIH in SOC individuals. Studies with larger sample sizes are indicated.  J Drugs Dermatol. 2024;23(5):316-321. doi:10.36849/JDD.8146.

Central toxic keratopathy leading to epithelial ingrowth following femtosecond LASIK.

We report a case of a woman in her 30s who underwent femtosecond LASIK (laser-assisted in situ keratomileusis) in both eyes to correct her simple myopic astigmatism. After the surgery, both eyes developed diffuse lamellar keratitis, and intensive topical steroids were initiated to control the same. Subsequently, central toxic keratopathy (CTK) developed bilaterally. Three weeks after the surgery, the right eye showed signs of progressive epithelial ingrowth involving the pupillary area. Surgical intervention in the form of flap relift followed by debridement of the epithelial cells and an alcohol interface wash were performed to treat the same. This is the first report of an epithelial ingrowth following CTK after femtosecond LASIK.

Postoperative Complications of Flap Procedures in Chest Wall Defect Reconstruction: A Two-Center Experience.

Background and Objectives: Chest wall defect reconstruction is a complex procedure aimed at restoring thoracic structural integrity after trauma, tumor removal, or congenital issues. In this study, postoperative complications were investigated to improve the care of patients with these critical conditions. Materials and Methods: A retrospective study of chest wall reconstructions from 2004 to 2023 was conducted at Klinikum Nürnberg and Evangelisches Waldkrankenhaus Spandau-Berlin. Data included patient demographics, comorbidities, defect etiology, surgery details, and complications using the Clavien-Dindo classification. Results: Among the 30 patients included in the study, a total of 35 complications occurred in 35 thoracic wall defect reconstructions. These complications were classified into 22 major and 13 minor cases. Major complications were more common in patients with cancer-related defects, and considerable variations were observed between free flap and pedicled flap surgeries. Notably, the use of the anterolateral thigh (ALT) flap with vastus lateralis muscle demonstrated promise, exhibiting fewer complications in select cases. The reconstruction of chest wall defects is associated with substantial complications regardless of the etiology of the defect and the particular surgical procedure used. Interestingly, there was a lower complication rate with free flap surgery than with pedicled flaps. Conclusions: The ALT flap with vastus lateralis muscle deserves further research in this field of reconstruction. Multidisciplinary approaches and informed patient discussions are crucial in this complex surgical field, emphasizing the need for ongoing research and technique refinement.

Retromesenteric omental flap as arterial coverage in pancreaticoduodenectomy: A novel technique to prevent postpancreatectomy hemorrhage.

BACKGROUND: Clinically relevant postpancreatectomy hemorrhage occurs in 10% to 15% of patients after pancreaticoduodenectomy, mainly in association with clinically relevant postoperative pancreatic fistula. Prevention of postpancreatectomy hemorrhage by arterial coverage with a round ligament plasty or an omental flap is controversial. This study assessed the impact of arterial coverage with an original retromesenteric omental flap on postpancreatectomy hemorrhage after pancreaticoduodenectomy. METHODS: This single-center retrospective study included 812 open pancreaticoduodenectomies (2012-2021) and compared 146 procedures with arterial coverage using retromesenteric omental flap to 666 pancreaticoduodenectomies without arterial coverage. The Fistula Risk Score was calculated. The primary endpoint was a 90-day clinically relevant postpancreatectomy hemorrhage rate according to the International Study Group of Pancreatic Surgery classification. RESULTS: There were more patients with a Fistula Risk Score ≥7 in the arterial coverage-retromesenteric omental flap group: 18 (12%) versus 48 (7%) (P < .01). Clinically relevant postpancreatectomy hemorrhage was less frequent in the arterial coverage- retromesenteric omental flap group than in the no arterial coverage group: 5 (3%) versus 66 (10%), respectively (P = .01). Clinically relevant postoperative pancreatic fistula occurred in 28 (19%) patients in the arterial coverage- retromesenteric omental flap group compared with 165 (25%) in the no arterial coverage group (P = .001). There were fewer reoperations for postpancreatectomy hemorrhage or postoperative pancreatic fistula in the arterial coverage- retromesenteric omental flap group: 1 (0.7%) versus 32 (5%) in the no arterial coverage group (P = .023). In multivariate analysis, arterial coverage with retromesenteric omental flap was an independent protective factor of clinically relevant postpancreatectomy hemorrhage (odds ratio 0.33; 95% confidence interval [0.12-0.92], P = .034) whereas postoperative pancreatic fistula of any grade (odds ratio = 10.1; 95% confidence interval: 5.1-20.3, P < .001) was predictive of this complication. CONCLUSION: Arterial coverage with retromesenteric omental flap can reduce rates of clinically relevant postpancreatectomy hemorrhage after pancreaticoduodenectomy. This easy and costless technique should be prospectively evaluated to confirm these results.

The Breast-Pectoralis Flap: A New Advance in Autologous Breast Reconstruction-A Preliminary Report on 20 Cases.

BACKGROUND: In the past, several publications have described breast reconstruction techniques that utilize the contralateral breast; however, interest diminished because of technical difficulty, scarring, and poor aesthetic results. OBJECTIVES: This study aimed to present a new breast reconstruction technique that uses a combination of the breast-pectoralis flap and the abdominal advancement flap. METHODS: This retrospective study analyzed the results and complications of 20 consecutive breast reconstructions with the breast-pectoralis flap technique. RESULTS: The authors present a series of 20 breast reconstructions that utilized the breast-pectoralis flap. Delayed breast reconstruction was performed in 13 cases (65%), breast reconstruction in 5 patients (25%) with Poland syndrome, sequela correction after a chest wall sarcoma in 1 patient (5%), and sequela correction after breast cystic lymphangioma resection in 1 patient (5%). One complication required surgical reintervention without long-term consequences. The outcomes were considered very good in 50% of the cases, good in 45%, and fair in 5%. CONCLUSIONS: The combination of the breast-pectoralis flap and the abdominal advancement flap is an interesting advance in breast reconstruction. Evaluation of the presented cases suggests wider indications for this technique.

Synchronous supraclavicular vascularized lymph node transfer and liposuction for gynecological cancer-related lower extremity lymphedema: A clinical comparative analysis of three different procedures.

OBJECTIVE: Gynecological cancer-related lower extremity lymphedema (GC-LEL), a chronic, progressive condition, lacks a standardized treatment. Currently, supraclavicular vascularized lymph node transfer (SC-VLNT) is a favored approach in the treatment of lymphedema, and there is a trend toward combination technology. This study conducts a comparative analysis of three techniques for treating GC-LEL with simultaneous SC-VLNT and liposuction. METHODS: A cohort of 35 patients with GC-LEL was examined, comprising 13 patients who underwent single lymph nodes flap with a skin paddle (SLNF+P), 12 who received single lymph nodes flap without a skin paddle (SLNF), and 10 who accepted dual lymph nodes flap without a skin paddle (DLNF). Patient demographics and outcomes were meticulously documented, covering intra- and postoperative variables. RESULTS: The median limb volume reduction were 56.4% (SLNF+P), 60.8% (SLNF), and 50.5% (DLNF) in stage II, and 54.0% (SLNF+P), 59.8% (SLNF), and 54.4% (DLNF) in stage III. DLNF group procedures entailed longer flap harvesting and transplantation times. The SLNF+P group, on average, had an 8-day postoperative hospitalization, longer than others. All patients noted subjective improvements in Lymphedema Quality of Life scores, with lymphoscintigraphy revealing enhanced lymphatic flow in 29 of the 35 cases. A notable decrease in cellulitis incidence was observed. Additionally, the occurrence of cellulitis decreased significantly, except for DLNF (Stage Ⅱ). The median follow-up time was 16 months (range, 12-36 months), with no reported severe postoperative complications. CONCLUSIONS: For advanced GC-LEL, SLNF combined with liposuction is a preferred treatment, offering fewer complications, shorter operative time, and hospitalization.

Medication-related osteonecrosis of the jaw: Evaluation of a therapeutic strategy in oral surgery.

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a severe adverse illness linked to antiresorptive therapies (ART), for which there is no therapeutic gold standard. Many factors can influence MRONJ evolution such as cancer type, treatment, comorbidities, and accumulated dose of ART. The aim of this study was to determine the influencing factors of MRONJ treatments success. METHODS: This retrospective study focused on patients treated for MRONJ in a French tertiary centre. Non-operative therapy was always applied, ART were suspended if appropriate, and surgery (MRONJ removal and musculo-mucosal flap reconstruction) was performed in the absence of contraindication. The evaluation criteria were bone and mucosal healing 3 months after surgery. RESULTS: 81 MRONJ were included; medical treatment alone was administered to 26 % while the remaining 74 % received additional surgery. Therapeutic success reached 86.7 % (52/60) for surgery compared to 42.9 % (9/21) for medical treatment alone (p < 0.001). Age (OR=1.08, p = 0.014) and the absence of infection (OR=5.32, p = 0.042) were in favour of success, while medical treatment alone (OR=0.03, p < 0.001) was highly unfavourable. CONCLUSION: MRONJ healing is influenced by age, non-infectious stages, and surgery. Additional surgery in MRONJ treatment should be advised if the health of the patient permits.

Direct Subscarpal Lipectomy Combined With Liposuction in Abdominoplasty: An Analysis of Safety and Efficacy in 200 Consecutive Patients.

BACKGROUND: Abdominoplasty procedures continue to evolve because combining techniques such as suction-assisted lipectomy or direct subscarpal lipectomy have proven to be powerful adjuncts to achieve optimal aesthetic results. However, concern has been expressed about combining techniques simultaneously given the potential to damage the vascularity of the abdominoplasty flap. OBJECTIVES: The aim of this study was to assess the safety and efficacy of simultaneous direct subscarpal lipectomy combined with liposuction in abdominoplasty patients. METHODS: A 4-year retrospective review of consecutive abdominoplasties (n = 200) performed by a single surgeon was conducted. Liposuction of the abdominal flap and flanks was performed in all patients. After raising the abdominoplasty flap, undermining was performed to just beyond the xyphoid, the lower rib margins superiorly, and the anterior axillary line laterally. Fat deep to Scarpa's fascia was then removed by direct tangential excision in all zones of the abdominal flap. RESULTS: The patients had a mean age of 42.19 years and BMI of 28.10 kg/m2; the mean follow-up time was 7 months. Seroma occurred in 13 patients (6.5%), superficial wound dehiscence treated with local wound care in 16 patients (8%), hypertrophic scarring in 16 patients (8%), partial umbilical necrosis in 1 patient (0.5%), and partial umbilical epidermolysis in 6 patients (3%). No patients experienced major or minor full-thickness tissue loss. No patients needed reoperation. CONCLUSIONS: Simultaneous direct excision of subscarpal fat with liposuction of the abdomen and flanks does not appear to subject any zone of the abdominoplasty flap to increased risks of vascular compromise. No flap necroses were observed. The technique described is safe and may provide superior abdominoplasty results.

Prophylactic Transversely Hemisected Sartorius Flap for High-Risk Groin Dissections in Vascular Surgery-A Case Series.

Groin wound dehiscence and infection are a common complication of femoral artery exposure. In patients with prosthetic conduits placed in the groin, these complications can lead to graft infection or anastomotic dehiscence with hemorrhage. Sartorius flaps can be useful in preventing graft infections or anastomotic breakdown in the setting of wound infections. Prophylactic sartorius flaps have been suggested to be a useful adjunct in patients who are at high risk for groin complications. Standard sartorius flaps can be difficult to perform and increase the operative time. We present our experience with a modified sartorius flap, a Transversely Hemisected Sartorius (THT), which avoids dissection to the anterior superior iliac spine. Patients who received femoral artery exposure and a modified prophylactic sartorius flap were included in this case series. The Penn Groin Assessment Scale (PGAS) was calculated for each patient and our primary outcome was the rate of deep space wound infections. Fifteen patients received a THT muscle flap. The average age of the cohort was 67.5 (35-86) years. Eight (50%) were male. The mean PGAS was 2.5 (0-6). Eight (50%) groins had a prosthetic conduit underlying the flap. Four (25%) patients had infrainguinal bypass, 3 (18.8%) for femoral-femoral bypass, and 1 (6.3%) patient received aortic-bifemoral bypass. Eight (50%) patients received sartorius flap after femoral artery exposure for thromboembolectomy, endarterectomy, or access complications. Six (37.5%) patients developed superficial surgical site infections however no deep space infections or prosthetic graft excisions resulted. This procedure was effective in preventing graft infections in all patients with high-risk features for groin infection in our retrospective case series. The segmental blood supply is maintained while providing good coverage of the femoral vessels with this rotational flap.

Validated Symptom Outcomes Following Septal Perforation Repair: Application of the NOSE-Perf Scale.

OBJECTIVE: The Nasal Obstruction Symptom Evaluation (NOSE)-Perf scale was developed and validated to measure symptoms associated with nasal septal perforations. This study reports the application of the NOSE-Perf scale to evaluate symptom change following septal perforation repair. METHODS: Patients with NOSE-Perf evaluations ≥6 months following attempted perforation closure from July 2018 to December 2021 utilizing bilateral nasal mucosal flaps with an interposition graft were eligible for study inclusion. Change in NOSE-Perf scores were noted. Patient demographics, perforation size, and concurrent functional procedures were analyzed for impact on symptom outcomes. RESULTS: One-hundred and seventeen patients met the study criteria. Seventy-nine (67.5%) of the patients were female and the mean (range) age at surgery was 47.3 (14-78) years. Repair failure was noted in 7 (6.0%) patients. Mean (SD) preoperative NOSE-Perf score was 25.3 (95% CI, 23.5-27.1) and postoperative score was 7.9 (95% CI, 6.5-9.3). Minimal clinically important difference (MCID) was estimated and greater than 91% of patients had improvement above this threshold. Patient age, perforation size, or concurrent functional procedures did not impact outcomes. Postoperative scores at short (2-4 months), intermediate (5-8 months), and long-term (≥9 months) time periods showed significant improvement (all p < 0.001) compared to preoperative NOSE-Perf scores. CONCLUSION: Significant reduction in nasal symptoms as measured by the NOSE-Perf scale is noted following bilateral mucosal flap repair. Although the nose does not completely normalize following repair, clinically important improvement was noted in at least 91% of patients. The NOSE-Perf scale is positioned to play a role in the standardization of septal perforation evaluation and outcomes assessment. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:3067-3072, 2024.

Single Surgeon Comparison of Midline Versus Overlapping Locoregional Flap Closure Following Spinal Instrumentation.

BACKGROUND: Two techniques for paraspinous muscle flap closure of spine surgeries have been described: one with tension-free mobilization of the muscle flaps approximated at the midline and one with perforators more aggressively dissected to allow for overlapping of the flaps. We seek to compare the surgical outcomes in patients who underwent either type of complex spinal closure as no investigation has yet evaluated a superior technique. METHODS: An institutional review board (IRB)-approved retrospective analysis was conducted on all patients who underwent spine surgery followed by locoregional muscle flap complex closure performed by a single plastic surgeon between January 2016 and July 2021. Patients were divided into 2 groups based on which closure method was employed. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed by multivariable logistic regression with Firth's correction. RESULTS: One hundred and 10 patients with similar baseline demographics were included. There were significantly more smokers (15% vs. 0%, P = 0.02) and a significantly greater rate of postoperative radiation (40% vs. 17%, P = 0.009) in the overlapping group. After controlling for smoking and postoperative radiation, the incidence of surgical site infection, skin necrosis, dehiscence, hematoma, and seroma did not differ between the groups. The procedure length per centimeter of closure was shorter in the midline approximation group, although this data fell just short of significance (3.2 vs. 3.8 minutes/cm, P = 0.08). CONCLUSIONS: The present study demonstrates that both the overlapping and midline approximation of muscle flaps are equally safe and effective strategies for locoregional closure of spinal wounds.

Reconstruction of Broad Lower Lip Defects Using Karapandzic-Type Flaps.

BACKGROUND: Reconstruction of lower lip defects is challenging because of the functional and aesthetic demands of the lower face. We review the functional and aesthetic outcomes of the Karapandzic-type flaps for reconstructing lower lip defects. METHODS: A retrospective review of patients who underwent repair using Karapandzic-type flaps. RESULTS: Fifty patients with lower lip defects ranging from 20% to 95% (mean 59.2% ± 20%) were included. Eighteen patients (36%) were repaired using a bilateral flap, and 32 (64%) were reconstructed using a unilateral flap design. All patients had preservation of oral competency and a satisfactory aesthetic result. No patient complained of microstomia. A complication rate of 8% was noted ( n = 4) with postoperative wound infection and small areas of dehiscence. There was no statistically significant difference in complication rates in patients older than 75 years, in patients with a history of head/neck radiation, or in defects greater than 70% of lower lip breadth. CONCLUSION: Karapandzic-type flaps are versatile and reliable for the reconstruction of a broad range of lower lip defects. This one-stage procedure can produce superior functional and aesthetic results as compared with other local and distant flaps with minimal risk of functional microstomia.

Improved rehabilitation efficiency after cranioplasty in patients with sunken skin flap syndrome: a case series.

PURPOSE: Sunken Skin Flap Syndrome (SSFS) is an uncommon, delayed complication after craniectomy characterized by a functional plateau or decline with variable neurologic symptoms, improving after cranioplasty. SSFS negatively impacts the rehabilitation course, with subjective reports of functional improvement after cranioplasty. However, no studies have assessed the impact of cranioplasty on functional recovery rate. This case series aims to analyze SSFS manifestations and management while awaiting cranioplasty. Also, to assess the role of cranioplasty on rehabilitation outcomes and recovery rate in SSFS patients. METHODS: Four patients were identified with SSFS in inpatient rehabilitation. Each patient had unique clinical manifestations, with multiple strategies used for symptomatic control. Patients spent an average of 23 days in rehabilitation with SSFS symptoms before cranioplasty. After cranioplasty, all patients had SSFS symptom resolution. Comparing change in functional independence measure (FIM) scores and FIM efficiency pre-and post-cranioplasty rehabilitation course, a mean improvement of 23 and 0.72 occurred after cranioplasty, respectively. CONCLUSION: A diagnosis of SSFS should be considered in craniectomy patients exhibiting functional decline or plateau with associated neurological symptoms. This study suggests that FIM and FIM efficiency increases in SSFS patients after cranioplasty, supporting prompt cranioplasty to improve functional outcomes and minimize rehabilitation delays.

Empiric flap coverage for the pneumonectomy stump: How protective is it? A single-institution cohort study.

OBJECTIVE: To evaluate the impact of empiric tissue flaps on bronchopleural fistula (BPF) rates after pneumonectomy. METHODS: Patients who underwent pneumonectomy between January 2001 and December 2019 were included. Primary end point was development of BPF. Secondary end points were impact of flap type on BPF rates, time to BPF development, and perioperative mortality. RESULTS: During the study period, 383 pneumonectomies were performed; 93 were extrapleural pneumonectomy. Most pneumonectomy cases had empiric flap coverage, with greater use in right-sided operations (right: 97%, 154/159; left: 80%, 179/224, P < .001). Empiric flaps harvested included intercostal, latissimus dorsi, serratus anterior, omentum, pectoralis major, pericardial fat/thymus, pericardium, and pleura. BPF occurred in 10.4% of the entire cohort but decreased to 6.6% when extrapleural pneumonectomy cases were excluded; 90% (36/40) of BPFs occurred on the right side (P < .001). Median time to develop BPF was 63 days, and 90-day mortality was greater in patients with BPF (12.5% BPF vs 7.4% non-BPF, P < .0001). Intercostal muscle had the lowest rate of BPF (4.5%), even in right-sided operations (8.7%). In contrast, larger muscle flaps such as latissimus dorsi (21%) and serratus anterior (33%) had greater rates of BPF, but the sample size was small in these cohorts. CONCLUSIONS: Empiric bronchial stump coverage should be performed in all right pneumonectomy cases due to greater risk of BPF. In our series, intercostal muscle flaps had low BPF rates, even in right-sided operations. Coverage of the left pneumonectomy stump is unnecessary due to low incidence of BPF in these cases.

Risk factors and consequences of wound complications following sartorius flap reconstruction.

OBJECTIVE: Groin wound complications are common following vascular surgery and can lead to significant patient morbidity. Sartorius muscle flap coverage may help to prevent vascular graft infection in the setting of wound dehiscence or infection. However, risk factors and consequences of wound complications following sartorius flap reconstruction remain incompletely investigated. METHODS: We retrospectively queried all patients who underwent sartorius flap reconstruction at a tertiary academic medical center. Data collected included patient demographics, medical comorbidities, surgical indication, index vascular procedure, and postoperative outcomes. The primary outcome was wound complication following sartorius flap procedure, which was defined as groin wound infection, dehiscence, or lymphocutaneous fistula. RESULTS: From 2012 to 2022, a total of 113 patients underwent sartorius flap reconstruction. Of these, 66 (58.4%) were performed after the development of a prior groin complication, and 47 (41.6%) were prophylactic. A total of 88 patients (77.9%) had a prosthetic bypass graft adjacent to the flap. Twenty-nine patients (25.7%) suffered a wound complication following sartorius flap reconstruction, including 14 (12.4%) with wound dehiscence, 13 (11.5%) with wound infection, and two (1.8%) with lymphocutaneous fistula. Patients with wound complications had a higher body mass index (28.8 vs 26.4 kg/m2; P =.03) and more frequently active smokers (86.2% vs 66.7%; P = .04). Additionally, patients with wound complications had a higher unplanned 30-day hospital readmission rates (72.4% vs 15.5%; P < .001), reintervention rates (75.9% vs 8.3%; P < .001), and re-do flap reconstruction rates (13.8% vs 2.4%; P = .02). On multivariable analysis, higher body mass index was independently associated with post-flap wound complications (adjusted odds ratio [aOR], 1.01; 95% confidence interval [CI], 1.001-1.03; P = .037). Consequently, wound complications were associated with both surgical reintervention (aOR, 35.4; 95% CI, 9.9-126.3; P < .001) and unplanned hospital readmission (aOR, 17.8; 95% CI, 5.9-54.1; P < .001). CONCLUSIONS: Sartorius flap reconstruction is an effective adjunct in facilitating wound healing of groin wounds. However, wound complications are common following sartorius flap reconstruction and may be associated with reintervention and unplanned hospital readmission. These data support the judicious and thoughtful utilization of sartorius flap procedures among high-risk patients.

Efficacy and safety of surgical excision and reconstruction combined with radiotherapy for huge keloids: A 13-year experience.

BACKGROUND: Surgical excision combined with radiotherapy is considered an effective treatment for keloids, while the efficacy and safety of this regimen for huge keloids in patients who need reconstruction after excision is still unclear. Therefore, this study aimed to evaluate the efficacy and safety of surgical excision and reconstruction combined with radiotherapy for huge keloids in a single center with 13 years of experience. METHODS: All consecutive patients with huge keloids who underwent surgical excision and reconstruction combined with radiotherapy were identified. Demographic information, prior interventions for keloids, parameters and complications, and recurrence rates were documented. RESULTS: Twenty-one patients (10 males; mean age, 43.19 ± 18.15 years) were included, 14 patients reconstructed with z-plasties, 5 with skin grafts, and 2 with skin flaps. During a mean follow-up of 75 months, one patient developed local necrosis without the need for revision surgery and two patients developed temporary hyperpigmentation. Two patients with the z-plasties suffered partial keloids recurrence, which was healed with corticosteroid injection. No wound infection, hematoma, telangiectasia, or new keloids at donor sites were observed. The overall appearance of reconstructed defects was aesthetically acceptable. CONCLUSION: Surgical excision and reconstruction combined with radiotherapy may be safe and effective for huge keloids.

New and Recurrent Ulcerations after Free Tissue Transfer with Partial Bony Resection in Chronic Foot Wounds within a Comorbid Population.

BACKGROUND: Chronic foot wounds often require bony resection; however, altering the tripod of the foot carries a risk of new ulcer development nearing 70%. Resulting defects often require free tissue transfer (FTT) reconstruction; outcomes data for various bony resection and FTT options may guide clinical decision-making regarding bone and soft-tissue management. The authors hypothesized that alteration of the bony tripod will increase risk of new lesion development after FTT reconstruction. METHODS: A single-center retrospective cohort analysis of patients undergoing FTT from 2011 through 2019 with bony resection and soft-tissue defects of the foot was performed. Data collected included demographics, comorbidities, wound locations, and FTT characteristics. Primary outcomes were recurrent lesion (RL) and new lesion (NL) development. Multivariate logistic regression and Cox hazards regression were used to produce adjusted odds ratios and hazard ratios. RESULTS: Sixty-four patients (mean age, 55.9 years) who underwent bony resection and FTT were included. Mean Charlson Comorbidity Index was 4.1 (SD 2.0), and median follow-up was 14.6 months (range, 7.5 to 34.6 months). Wounds developed after FTT in 42 (67.1%) (RL, 39.1%; NL, 40.6%). Median time to NL development was 3.7 months (range, 0.47 to 9.1 months). First-metatarsal defect (OR, 4.8; 95% CI, 1.5 to 15.7) and flap with cutaneous component (OR, 0.24; 95% CI, 0.07 to 0.8) increased and decreased odds of NL development, respectively. CONCLUSIONS: First-metatarsal defects significantly increase NL risk after FTT. The majority of ulcerations heal with minor procedures but require long-term follow-up. Soft-tissue reconstruction with FTT achieves success in the short term, but NL and RL occur at high rates in the months to years after initial healing. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.
