Implant-based breast reconstruction (IBBR) remains the most common form of post-mastectomy reconstruction worldwide, offering patients a reliable and accessible option to restore breast contour. Advances in surgical technique, biomaterials, and implant technology have driven rapid evolution in the field, with the dual goals of improving aesthetic outcomes and minimizing patient morbidity. The prepectoral plane has been popularized due to the eliminated risk of animation deformity and reduced postoperative pain. Some concerns remain regarding mastectomy flap thickness and long-term oncologic and aesthetic outcomes. Concurrently, nipple-sparing mastectomy has improved aesthetic results and enabled surgeons to move beyond just restoring breast form and improve functional recovery as well, as demonstrated by surgical efforts aimed at restoring nipple-areolar complex (NAC) sensation. Adjunctive use of biologic matrices and synthetic meshes has broadened reconstructive options, while next-generation implants seek to further enhance outcomes. Balanced against these innovations are important oncologic and systemic safety concerns, including breast implant-related cancers and the ongoing debate over breast implant illness (BII). This review highlights eight current "hot topics" in implant-based breast reconstruction: (1) prepectoral reconstruction, (2) nipple-sparing mastectomy, (3) oncoplastic techniques, (4) nipple-areolar complex (NAC) neurotization, (5) biologic matrices and synthetic meshes, (6) next-generation implants, (7) optimizing aesthetic outcomes, and (8) implant-associated cancer and systemic concerns. Together, these areas define the current landscape of innovation, controversy, and future directions in implant-based reconstruction.

Chronic wounds, especially in diabetic patients, pose a significant clinical challenge due to impaired microvasculature and delayed healing. This study presents Exo-Q, a novel thermoresponsive hydrogel formed by co-gelation of engineered Q protein nanofibers with exosomes, a class of vesicular intercellular communication mediators. Exo-Q transitions from a gel to a viscoelastic solution at physiological temperature, enabling localized, topical delivery of exosomes with an initial burst release followed by sustained release. In a diabetic mouse wound model, Exo-Q effectively delivered human bone marrow multipotent stromal cell-derived exosomes directly to the wound bed, where they accumulated in endothelial cells of granulation tissue without detectable systemic distribution. Exosomes produced under stringent and replicable cell culture conditions consistently carried biomacromolecular cargo enriched for miRNAs with validated targets in angiogenesis-associated genes, indicative of their therapeutic potential. Topical application of Exo-Q resulted in extensive neovascularized granulation tissue, significantly accelerating wound closure to levels comparable to non-diabetic wounds. Importantly, the hydrogel's modular design maintained the functional integrity of Q protein nanofibers and exosomes, demonstrating compatibility with full-thickness human wounds. This platform allows for tailored customization to address critical stages of diabetic wound healing while ensuring efficacy at low dosages, potentially enabling patient-administered treatment. By leveraging advanced biomaterials, Exo-Q advances the therapeutic efficacy of exosome-based interventions for diabetic wounds, offering a localized, non-invasive solution to chronic, non-healing wounds. This innovative hydrogel platform represents a modular therapeutic strategy with significant potential for clinical applications in regenerative medicine.

Pancreatic ductal adenocarcinoma (PDAC) with extensive peripancreatic vessel involvement is classified as locally advanced pancreatic cancer (LAPC). For this group of patients, the current standard of care does not include considering a potentially curative oncologic resection. However, recent advances in multiagent chemotherapy and surgical techniques are challenging this paradigm. Moreover, the current determination of anatomic resectability is vague and unreliable. Here we propose a definition of local resectability, based on pre- and intra-operative assessment. This anatomic definition of resectability assumes careful patient selection based on tumor biology and patient condition. The pre-operative evaluation of vascular anatomy and tumor involvement is conducted using 3D-rendering of pancreas-protocol computed tomography. Identifying a disease-free arterial or venous segment above and below the tumor involvement ("suitable target") is the single critical factor that determines anatomic resectability. Intraoperative isolation of these target vessels confirms the feasibility of vascular reconstruction before resection. This approach, which focuses on identifying target vessels rather than circumferential involvement, offers a more straightforward and clinically relevant method for assessing surgical eligibility in LAPC patients at centers of excellence. In summary, reconstructability-based on surgical expertise and guided by tumor biology-now defines the modern paradigm of resectability in LAPC.

BACKGROUND:Congenital palatal fistula (CPF), most often associated with submucous cleft palate (SMCP), is a rare clinical entity. Surgical management is challenging owing to anatomical variation and risk of persistent velopharyngeal insufficiency (VPI). We reported outcomes from a case series of 27 patients with CPF associated with SMCP managed using a standardized institutional algorithm. METHODS:A retrospective review was conducted at CLAPP Hospital, Lahore, from 2015 to 2020. Patients with CPF associated with SMCP were included; acquired fistulae and syndromic cases were excluded. Fistulae were classified using the Pakistan Comprehensive Fistula Classification Scheme. SMCP was further stratified according to the CLAPP Classification and Treatment Algorithm, guiding surgical approach (midline incision, modified Langenbeck, or standard Langenbeck with/without adjunctive procedures). Outcomes included fistula recurrence and speech results. RESULTS:The cohort comprised 27 patients (mean age 9.9 years; range 1-23 years), and 52% were female. Two patients (7.4%) developed postoperative fistula recurrence. Preoperatively, 94% of patients had severe hypernasality (G3). Postoperatively, mean composite speech scores improved by 52.3% (14.9→7.1). Fourteen patients [14/17 (82.4%)] achieved G0/G1 (normal resonance). Younger patients (<12 years) showed greater improvement (90% to G0/G1) compared to older patients (71.4%). No middle-ear sequelae were observed. CONCLUSIONS:A tailored algorithmic approach for CPF associated with SMCP yielded low recurrence (7.4%) and substantial speech improvement. Younger patients demonstrated greater postoperative speech benefit, underscoring the importance of early diagnosis and repair.

BACKGROUND:Body contouring surgery (BCS) is a common postoperative trajectory for adults following bariatric surgery, yet research on its application to adolescents is lacking. This scoping review aimed to map the available literature on quality of life (QoL) and potential for BCS in adolescents after bariatric surgery. METHODS:This review followed the Joanna Briggs Institute (JBI) guidance for scoping reviews and is reported in accordance with the PRISMA extension for Scoping Reviews (PRISMA-ScR). Three electronic databases were queried for studies regarding QoL and BCS in adolescents following bariatric surgery within the last 20 years. A descriptive and thematic analysis was conducted. RESULTS:Twenty-three studies met inclusion criteria. A total of 19 (82.6%) evaluated QoL and 4 (17.4%) explored the role of BCS in adolescents following bariatric surgery. The most common method of data collection was prospective study (65.2%). Two themes were described: QoL after bariatric surgery, which expressed improvement in several domains within 6 months, and role for BCS, which showed high interest in addressing residual excess skin and appearance. Gaps in the literature were identified, including a need for studies exploring mediators of QoL, predictors of compliance, and outcomes of BCS. CONCLUSIONS:Studies describing residual symptoms and BCS in adolescents following bariatric surgery are lacking. BCS may complement bariatric surgery, but further research must be conducted to assess its safety in adolescents. By addressing the research gaps described in this review, physicians may have a better understanding of the needs of this population and how to counsel them.

BACKGROUND:Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition often requiring surgical intervention for definitive treatment. Previous studies evaluated post-surgical outcomes, but no standardization exists for collection and nomenclature for HS surgical outcomes. OBJECTIVE:To characterize and define surgical outcome terminology. METHODS:A modified Delphi protocol was used to reach consensus on data to collect and terms to describe outcomes following HS surgical procedures. A five-member steering committee created preliminary definitions and surveys which were distributed via Qualtrics to a group of international HS experts. A nine-point Likert scale was used and a score of at least 7 was needed for an item to reach agreement. RESULTS:Twenty-five dermatologists and general and plastic surgeons participated in the Delphi study. Following two rounds of surveys and feedback, the consensus terminology to describe outcomes included surgical site and regional persistence and progression. Consensus was also reached on key features to report as part of each outcome. LIMITATIONS/CONCLUSIONS:Limitations include narrow scope and small number of participants from limited geographical areas. CONCLUSION/CONCLUSIONS:Surgery persistence and progression definitions were agreed upon by a group of international HS experts. This consensus is a first step towards standardizing terminology and reporting for HS surgical outcomes.

Patients requiring breast reconstruction following radiation therapy or prior failed autologous breast reconstruction (ABR) or implant-based breast reconstruction (IBBR) represent a challenging cohort and often present with compromised vascularity, scarred anatomy, and subsequent increased rates of complications. In this review, we discuss microsurgical strategies designed to optimize donor tissue in these challenging clinical scenarios, including the use of stacked or bipedicled flaps, and the utility of intraoperative indocyanine green angiography. We also review approaches to alternate recipient vessel selection in the suboptimal chest, and we address specific strategies for the revision setting, like soft tissue support and hybrid reconstruction with ABR and IBBR. By synthesizing the current literature and expert experience, this narrative review provides a practical framework for microsurgeons managing complex breast reconstruction in higher-risk patients.

Prepectoral breast reconstruction offers esthetic and recovery advantages but may be more vulnerable to complications due to the absence of muscular coverage. This study examined the clinical course of patients with failed prepectoral implant reconstruction. All consecutive prepectoral reconstructions performed between March 2017 and July 2022 at a single tertiary center were reviewed. Of 239 reconstructions, 42 (17.5%) ultimately failed, most commonly due to infection (50%). Sixteen patients (38%) underwent definitive reconstruction with a median interval of 379 days (IQR 249) from initial surgery to final reconstruction. The most common secondary reconstruction modalities were implant-based reconstruction (31%) and free-tissue transfer (31%). On multivariate analysis, increasing age, higher body mass index (BMI), and prior radiation were independently associated with implant loss. Failure of salvage after prepectoral reconstruction remains a major challenge and often results in delayed or abandoned reconstruction, highlighting the need for careful patient selection.

BACKGROUND:Umbilicoplasty is a critical step in donor-site closure following abdominally based autologous breast reconstruction (ABR). While various incision designs and transposition techniques have been described, their impact on patient- and surgeon-assessed aesthetic outcomes remains poorly defined. METHODS:A systematic review was conducted following PRISMA guidelines. PubMed, Ovid EMBASE, and Cochrane Library were searched through August 1, 2025, for studies evaluating umbilicoplasty after ABR. Eligible studies included randomized controlled trials, cohort studies, and case series reporting surgical technique, aesthetic, and/or patient satisfaction outcomes. Data extraction included study characteristics, surgical techniques, patient- and surgeon-assessed aesthetic outcomes, and complications. Risk of bias was assessed using standardized tools. RESULTS:Eight studies comprising 362 patients met inclusion criteria. Umbilicoplasty techniques varied, including oval, U/inverted-U, and Mercedes/inverted Mercedes as well as a neo-umbilicoplasty approaches. Complication rates were low with hypertrophic scarring and umbilical stenosis being most common. Aesthetic outcomes were variably reported, with limited use of validated scales, but generally favored designs that avoid an uninterrupted oval. CONCLUSION/CONCLUSIONS:While reported complication rates are low, methodological limitations and underreporting preclude definitive conclusions about technique safety or superiority. Umbilicoplasty should be individualized, with careful attention to perfusion. Future studies should prioritize standardized reporting, validated outcome measures, and multicenter collaboration to strengthen the evidence base and guide best practices in abdominally based breast reconstruction.
