Prelamination of Vascularized Tensor Fascia Lata for Complex Abdominal Wall Reconstruction.

ABSTRACT: There are 2 to 5 million laparotomies performed in the United States annually. Of these, 250,000 to 350,000 will undergo a ventral hernia repair. Repairs are often complicated by recurrence and infection. These risks are significantly increased in previously infected repairs, with reported recurrence rates varying from 17% to 28% after repair of infected ventral hernias, double the rates reported for first-time uninfected repairs. We describe here a novel treatment strategy involving the creation then use of bilateral prelaminated permanent mesh-reinforced tensor fascia latae flaps for abdominal wall reconstruction in patients who have recurrent ventral hernias and had undergone previous repairs complicated by infection. Previous repairs included anterior components separation, thereby making subsequent fascial release techniques and achievement of a reinforced repair extremely unlikely. Three patients were treated by a single surgeon using this 2-stage technique. There have been no incidences of recurrence and no infections after 2 to 10 years. In these patients, the only conventional option would have been a bridged repair with absorbable mesh. Combining the advantages of permanent mesh and well-vascularized autologous tissue optimizes the repair's tensile strength while mitigating the chance of recurrent infection associated with the use of permanent mesh. We propose that this strategy may be an appropriate treatment option for patients with recurrent ventral hernias that have not responded to other conventional modalities of treatment.

Evidence-Based Gardening: Using Palliative Approaches to Cure Complex Wounds.

Complex wounds are commonly thought to require aggressive surgical intervention to achieve healing. However, optimal healing results can often be achieved when greater emphasis is placed on optimizing patient factors prior to any surgical intervention. A retrospective review was performed of pressure ulcers and complex wound cases treated over 5 years at the Yale New Haven Wound Center. Optimal healing including clinical resolution of osteomyelitis and improved scarring was achieved when patient factors, such as glucose control and nutrition, were optimized. Surgical intervention can be more effective and even avoided entirely with the appropriate focus on optimizing patient factors.

Can Nicotine Replacement Therapy Decrease Complications in Plastic Surgery?

Cigarette smoking has been well demonstrated to be associated with adverse outcomes and increased complications in surgical patients in the operative and postoperative periods. There is general agreement that smoking cessation decreases such risks; however, much debate still exists regarding the most effective modalities for risk mitigation, especially concerning modalities involving nicotine replacement in some form. This article reviews the discussion regarding smoking cessation therapies, in particular those involving nicotine replacement, in the context of mitigating risk in plastic surgery procedures. The recent rise in popularity of electronic cigarettes poses further challenges for clinicians in minimizing risk and optimizing outcomes for patients. Prospective studies including high-level evidence such as randomized controlled clinical trials will be required to help plastic surgeons develop guidelines that will enable optimization of patient safety and clinical outcomes.

An Algorithm for the Management of Residual Head and Neck Melanoma In Situ Using Topical Imiquimod: A Pilot Study.

INTRODUCTION: Melanoma in situ (MIS) is an early variant of melanoma in which the disease is limited to the epidermis. Standard therapy is currently surgical excision with at least 5-mm margins. In some instances, there are large or anatomically difficult lesions where complete excision will result in significant esthetic or functional impairment. Our experience has shown a 6-week course to be sufficient in certain patients compared with the suggested 12-week course. In this context, we propose a shortened duration of treatment of positive margins with topical imiquimod and propose an algorithm that results in the least amount of dysfunction for the patient. METHODS: Our inclusion criteria were patients undergoing excision of a lesion found to have postsurgical margins, which were positive for MIS. Patients applied 5% imiquimod 3 to 5 times per week for at least 6 weeks at the site of the positive margin(s). Duration and frequency of treatment were titrated based on response. A reexcision skin biopsy using 1-mm margins was performed after residual inflammation subsided. Our endpoints were recurrence and effectiveness with length of treatment. RESULTS: Sixteen patients met our criteria. All patients were found to have MIS in the margins after surgical excision. Twelve of those lesions were classified as MIS in the initial biopsy; the remaining 4 were either melanoma stage T1A or T1B. Mean follow-up time was 14.3 months, and 1 patient was lost to follow-up. We had 3 patients without response, and of these, 1 was found to have atypical squamous cell carcinoma and the other had a recurrence of MIS. Cure rate after use of topical imiquimod was 93.3% (14/15). DISCUSSION: The proposed algorithm for the treatment of residual disease in head and neck melanoma and MIS using topical imiquimod offers various advantages. This anatomical region is cosmetically sensitive, and the option of using 1 mm versus 5 mm reexcision margins after imiquimod treatment yields comparable cure rates with less tissue excised overall. Our algorithm demonstrates that 6 weeks of active inflammation provides comparable results with the traditional 12-week course. This decreased treatment time reduces patient discomfort and improves patient adherence.

Clinical Value of Single-photon Emission Computed Tomography Combined With Computed Tomography for Sentinel Lymph Node Identification in Melanoma.

INTRODUCTION: Melanoma is the deadliest form of skin cancer and has the ability to metastasize widely. Accurate diagnosis of sentinel lymph nodes (SLN) is crucial to its management. The gold standard for SLN identification is planar lymphoscintigraphy. Recently, single-photon emission computed tomography combined with computed tomography (SPECT/CT) has been used as a hybrid method to map lymphatic drainage networks. We aim to better characterize the utility of this tool in head and neck melanoma by evaluating its effectiveness in the preoperative setting for melanoma patients undergoing sentinel lymph node biopsy (SLNB). METHODS: We performed a retrospective chart review at the West Haven Veterans Affairs Hospital. Inclusion criteria were patients with melanoma with a thickness greater than 0.75 mm and SPECT/CT use before operative sentinel lymph node excision. Exclusion criteria included clinically palpable lymph nodes, evidence of distant metastatic disease, melanoma with a Breslow depth less than 0.75 mm, and melanoma in situ. Our primary endpoints were correlation with intraoperative findings and whether the test had any influence on the operative plan. RESULTS: Thirty-five patients between 2011 and 2017 met our criteria. SPECT/CT correlated with the sentinel node biopsy based on intraoperative lymphoscintigraphy in 30 (86%) of 35 cases, and there were no changes to the operative plan after SPECT/CT was performed. Sentinel lymph nodes were correctly identified in all 35 cases. CONCLUSIONS: The role of SPECT/CT in SLNB is uncertain. According to some studies, SPECT/CT can help decision making and change surgical approach in up to 35% of patients. However, other studies have reported questionable correlation with intraoperative findings and no added intraoperative value in over 50% of patients. We have demonstrated that preoperative SPECT/CT was consistent with intraoperative findings in 86.0% of cases but did not change the surgical approach for the SLNB. Surveillance over a period of 12 months did not reveal any signs of melanoma recurrence. A possible advantage of SPECT/CT is potentially decreasing costs by lowering operative time. However, financial cost in the literature suggests SPECT/CT is costlier than lymphoscintigraphy and therefore this must be weighed against any potential benefit. Overall, we did not find that SPECT/CT gives added value when compared with lymphoscintigraphy.

Intraductal tubulopapillary neoplasms of the pancreas and biliary tract: The black swan of hepatobiliary surgery.

Intraductal tubulopapillary neoplasms (ITPNs) of the pancreas and biliary tract are rare pre-malignant entities of the biliary tract and pancreas that are difficult to diagnose preoperatively. While there are imaging characteristics that can differentiate these lesions from more common entities like adenocarcinoma or intraductal papillary mucinous neoplasms (IPMN), ITPNs are not always distinctive. Herein we present two cases of ITPN, one of biliary and the other of pancreatic origin, which had a preoperative diagnosis of cholangiocarcinoma and IPMN, respectively. We discuss our findings in these cases, patient presentation and course, review the radiographic and pathologic findings, and propose a more effective approach to the preoperative workup and diagnosis of ITPN based on our review of the contemporary literature.

Safety of compression therapy for venous ulcer disease in the setting of congestive heart failure.

OBJECTIVES: Compression therapy is the mainstay of treatment for patients with venous ulcer disease. There exists a lack of certainty as to the safety of compression therapy in patients with congestive heart failure. METHODS: A retrospective review of 95 patients with the diagnosis of congestive heart failure (systolic, diastolic, or combined), who underwent compression therapy at the wound care center of a large teaching hospital between January 2013 and June 2019, was performed. Patient outcomes including mortality, weight gain, admission for heart failure decompensation, and requirement for diuretic dose increase were compared to the general congestive heart failure population as well as to the registry data. RESULTS: In the compression cohort, with a mean compression period of 310 days, seven patients (7.3%) were admitted for congestive heart failure exacerbation and six (6.3%) underwent diuretic dosage increase. Two patients (2.1%) died during the compression period. These endpoints were not significantly higher than within the general congestive heart failure population. CONCLUSIONS: Compression therapy appears safe amongst patients with stable congestive heart failure.
