RESUMO

BACKGROUND: The lateral intercostal artery perforator (LICAP) flap aims at replacing the excised breast lump with axillary tissue rich blood supply. The purpose of this study is to report the initial results of a modification LICAP flap technique in terms of intraoperative technical feasibility and short-term cosmetic outcomes in the early postoperative period. METHODS: Modified LICAP flap technique was performed on 36 female patients with pathologically proven BC located in the outer half of the breast in the period from June 1, 2021, to April 30, 2022. RESULTS: The LICAP flap modification enabled performing the procedure with the patient in supine position without repositioning. The majority of the patients (90%) had satisfactory early cosmetic results as reported by the patients and oncoplastic independent surgeon. CONCLUSION: Modified LICAP flap reconstruction is feasible to be performed with the patient in supine position without repositioning and it has satisfactory early cosmetic outcomes.

RESUMO

OBJECTIVE: To examine liver retransplantation (ReLT) over 35 years at a single center. BACKGROUND: Despite the durability of liver transplantation (LT), graft failure affects up to 40% of LT recipients. METHODS: All adult ReLTs from 1984 to 2021 were analyzed. Comparisons were made between ReLTs in the pre versus post-model for end-stage liver disease (MELD) eras and between ReLTs and primary-LTs in the modern era. Multivariate analysis was used for prognostic modeling. RESULTS: Six hundred fifty-four ReLTs were performed in 590 recipients. There were 372 pre-MELD ReLTs and 282 post-MELD ReLTs. Of the ReLT recipients, 89% had one previous LT, whereas 11% had ≥2. Primary nonfunction was the most common indication in the pre-MELD era (33%) versus recurrent disease (24%) in the post-MELD era. Post-MELD ReLT recipients were older (53 vs 48, P = 0.001), had higher MELD scores (35 vs 31, P = 0.01), and had more comorbidities. However, post-MELD ReLT patients had superior 1, 5, and 10-year survival compared with pre-MELD ReLT (75%, 60%, and 43% vs 53%, 43%, and 35%, respectively, P < 0.001) and lower in-hospital mortality and rejection rates. Notably, in the post-MELD era, the MELD score did not affect survival. We identified the following risk factors for early mortality (≤12 months after ReLT): coronary artery disease, obesity, ventilatory support, older recipient age, and longer pre-ReLT hospital stay. CONCLUSIONS: This represents the largest single-center ReLT report to date. Despite the increased acuity and complexity of ReLT patients, post-MELD era outcomes have improved. With careful patient selection, these results support the efficacy and survival benefit of ReLT in an acuity-based allocation environment.

RESUMO

Intestinal microbiota is thought to play an important role in hepatic ischemia/reperfusion injury (IRI) after liver transplantation (LT). Rifaximin, a nonabsorbable antibiotic used to treat encephalopathy, exhibits antibacterial activity within the gut. We report the first study examining the impact of pre-LT rifaximin use on reducing hepatic IRI and inflammatory cell infiltration after LT. This retrospective single-center study included adult LT recipients from January 2013 through June 2016. Patients were divided into 2 groups based on duration of rifaximin use before LT: rifaximin group (≥28 days) and control group (none or <28 days). Patients receiving other antibiotics within 28 days of LT and re-LTs were excluded. Outcomes and messenger RNA (mRNA) expression in the graft were compared by 1:1 propensity score-matching and multivariate analyses. On 1:1 matching (n = 39/group), rifaximin patients had lower postoperative serum transaminase levels and lower early allograft dysfunction (EAD; 10.3% versus 33.3%; P = 0.014). Of the matched patients, 8 patients (n = 4/group) had postreperfusion liver biopsies (approximately 2 hours after reperfusion) available for mRNA analysis. Hepatic expression of CD86 (macrophage marker) and cathepsin G (neutrophil marker) was significantly lower in rifaximin patients than controls (P < 0.05). The multivariate analysis included 458 patients. Rifaximin treatment <28 days was identified as an independent risk factor EAD in all patients and those with high Model for End-Stage Liver Disease (MELD) score (MELD ≥35; n = 230). In conclusion, the propensity score-matched and multivariate analyses suggest a therapeutic role of rifaximin in reducing EAD. Pre-LT rifaximin administration exerted a protective function against early liver injury, potentially by suppressing inflammatory cell activation in the graft.

RESUMO

BACKGROUND: Kidney delayed graft function (kDGF) remains a challenging problem following simultaneous liver and kidney transplantation (SLKT) with a reported incidence up to 40%. Given the scarcity of renal allografts, it is crucial to minimize the development of kDGF among SLKT recipients to improve patient and graft outcomes. We sought to assess the role of preoperative recipient and donor/graft factors on developing kDGF among recipients of SLKT. METHODS: A retrospective review of 194 patients who received SLKT in the period from January 2004 to March 2017 in a single center was performed to assess the effect of preoperative factors on the development of kDGF. RESULTS: Kidney delayed graft function was observed in 95 patients (49%). Multivariate analysis revealed that donor history of hypertension, cold static preservation of kidney grafts [versus using hypothermic pulsatile machine perfusion (HPMP)], donor final creatinine, physiologic MELD, and duration of delay of kidney transplantation after liver transplantation were significant independent predictors for kDGF. kDGF is associated with worse graft function and patient and graft survival. CONCLUSIONS: Kidney delayed graft function has detrimental effects on graft function and graft survival. Understanding the risks and combining careful perioperative patient management, proper recipient selection and donor matching, and graft preservation using HPMP would decrease kDGF among SLKT recipients.

RESUMO

Importance: Anastomotic biliary complications (ABCs) constitute the most common technical complications in liver transplant (LT). Given the ever-increasing acuity of LT, identification of factors contributing to ABCs is essential to minimize morbidity and optimize outcomes. A detailed analysis in a patient population undergoing high-acuity LT is lacking. Objective: To evaluate the rate of, risk factors for, and outcomes of ABCs and acuity level in LT recipients. Design, Setting, and Participants: This retrospective cohort study included adult LT recipients from January 1, 2013, through June 30, 2016, at a single large urban transplant center. Patients were followed up for at least 12 months after LT until June 30, 2017. Of 520 consecutive adult patients undergoing LT, 509 LTs in 503 patients were included. Data were analyzed from May 1 through September 13, 2017. Exposure: Liver transplant. Main Outcomes and Measures: Any complications occurring at the level of the biliary reconstruction. Results: Among the 503 transplant recipients undergoing 509 LTs included in the analysis (62.3% male; median age, 58 years [interquartile range {IQR}, 50-63 years), median follow-up was 24 months (IQR, 16-34 months). Overall patient and graft survival at 1 year were 91.1% and 90.3%, respectively. The median Model for End-stage Liver Disease (MELD) score was 35 (IQR, 15-40) for the entire cohort. T tubes were used in 199 LTs (39.1%) during initial bile duct reconstruction. Overall incidence of ABCs included 103 LTs (20.2%). Anastomotic leak occurred in 25 LTs (4.9%) and stricture, 77 (15.1%). Exit-site leak in T tubes occurred in 36 (7.1%) and T tube obstruction in 16 (3.1%). Seventeen patients with ABCs required surgical revision of bile duct reconstruction. Multivariate analysis revealed the following 7 independent risk factors for ABCs: recipient hepatic artery thrombosis (odds ratio [OR], 12.41; 95% CI, 2.37-64.87; P = .003), second LT (OR, 4.05; 95% CI, 1.13-14.50; P = .03), recipient hepatic artery stenosis (OR, 3.81; 95% CI, 1.30-11.17; P = .02), donor hypertension (OR, 2.79; 95% CI, 1.27-6.11; P = .01), recipients with hepatocellular carcinoma (OR, 2.66; 95% CI, 1.23-5.74; P = .01), donor death due to anoxia (OR, 2.61; 95% CI, 1.13-6.03; P = .03), and use of nonabsorbable suture material for biliary reconstruction (OR, 2.45; 95% CI, 1.09-5.54; P = .03). Conclusions and Relevance: This large, single-center series identified physiologic and anatomical independent risk factors contributing to ABCs after high-acuity LT. Careful consideration of these factors could guide perioperative management and mitigate potentially preventable ABCs.
