Lymphaticovenular Anastomosis as a Treatment for Neurogenic Bladder in Patients With Lower Extremity Lymphedema After Gynecologic Cancer Treatment.

Background And Objectives: Neurogenic bladder (NB), a complication of gynecological cancer treatment, entails significant symptoms such as loss of urinary urgency, incontinence, and renal dysfunction. To investigate whether lymphatic fluid stagnation at the pelvis causes NB, we investigated the effectiveness of lymphaticovenular anastomosis (LVA) for NB.

Methods: In this retrospective study between 2014 and April 2024, LVA was performed on 52 patients complaining of preoperative urinary dysfunction with lower extremity lymphedema following pelvic lymphadenectomy in gynecologic cancer treatment.

The Dynamic Lymphaticovenular Anastomosis for Breast Cancer-related Lymphedema without Compression: Salvaging Lymphedema Patients Who Lost Conservative Treatment Opportunity.

Unlabelled: In conservative treatment for breast cancer-related lymphedema (BCRL), compression therapy has a crucial role. However, some BCRL patients are unable to use compression, and then their lymphedema continues to worsen as they miss treatment opportunity. Although lymphaticovenular anastomosis (LVA) is an effective and minimally invasive surgical treatment for BCRL, compression therapy is still important to enhance lymphatic fluid flow in LVA.

Matching the perforating branch of the internal thoracic artery and the deep inferior epigastric artery for breast reconstruction using multi-detector row computed tomography.

Purpose: Matching the diameter of the deep inferior epigastric artery (DIEA) and perforating branch (PB) of the internal thoracic artery (ITA) is important for arterial anastomosis during breast reconstruction using the DIEA flap. An anatomic investigation of these arteries was performed using multidetector row computed tomography (MDCT).

Patients And Methods: Contrast-enhanced MDCT data of 50 women (aged 18-90 years) covering the neck to the groin were analyzed.

Real-time Indocyanine Green Videolymphography Navigation for Lymphaticovenular Anastomosis.

Indocyanine green (ICG) lymphography is a useful imaging modality for evaluation of lymphedema and detection of lymphatic vessels. It also allows us to ensure patency of the anastomosed vessels intraoperatively. However, strong light from the operating microscope usually disturbs ICG fluorescence imaging.

The dynamic-lymphaticovenular anastomosis method for breast cancer treatment-related lymphedema: Creation of functional lymphaticovenular anastomoses with use of preoperative dynamic ultrasonography.

Background: Lymphaticovenular anastomosis (LVA) is generally an effective procedure for breast cancer treatment-related upper extremity lymphedema (UEL). Clinical improvement is, however, limited by the degree of sclerosis of the lymphatic vessels. We have developed a method by which we use dynamic ultrasonography to depict vessels through which lymph can be propelled into the LVA under the power of the patient's natural hand movements.

End-to-end and end-to-side neurorrhaphy between thick donor nerves and thin recipient nerves: an axon regeneration study in a rat model.

During nerve reconstruction, nerves of different thicknesses are often sutured together using end-to-side neurorrhaphy and end-to-end neurorrhaphy techniques. In this study, the effect of the type of neurorrhaphy on the number and diameter of regenerated axon fibers was studied in a rat facial nerve repair model. An inflow-type end-to-side and end-to-end neurorrhaphy model with nerve stumps of different thicknesses (2:1 diameter ratio) was created in the facial nerve of 14 adult male Sprague-Dawley rats.

Single Lymphaticovenular Anastomosis for Early-Stage Lower Extremity Lymphedema Treated by the Superior-Edge-of-the-Knee Incision Method.

Background: Surgical treatment of lower extremity lymphedema (LEL) remains challenging. Application of the superior-edge-of-the-knee incision method for lymphaticovenular anastomosis (LVA) is reported to have a strong therapeutic effect in patients with LEL because lymph-to-venous flow at the anastomosis is enhanced by knee joint movement during normal walking. We investigated whether a single LVA created by this method is adequate for early LEL.

Sudden shrinkage of free rectus abdominis musculocutaneous flap 15 years after maxilla reconstruction.

A 60-year-old male displayed sudden shrinkage of a left free rectus abdominis musculocutaneous flap, which had been grafted to his left maxilla 15 years previously. No post-reconstructive irradiation had been performed, and no late occlusion of the vascular anastomosis, local infection, recurrence of the maxillary cancer, or body weight loss was observed. However, the shrinkage amounted to approximately 50%.

Localized Leg Volume Index: A New Method for Body Type-Corrected Evaluation of Localized Leg Lymphedematous Volume Change.

Background: Volume measurement is one of the most common evaluations for lower-extremity lymphedema. However, volume comparison between different patients with different physique may be inappropriate, and it is difficult to evaluate localized limb volume change using leg volume evaluation.

Methods: Localized leg volumes (Vk, k = 1-5) and localized leg volume indices (LEVIk) at 5 points (1, thigh; 2, knee; 3, lower leg; 4, ankle; 5, foot) of 106 legs of 53 examinees with no leg edema were calculated based on physical measurements, leg circumferences and lengths, and body mass index (BMI).

Facial reanimation using hypoglossal-facial neurorrhaphy with end-to-side coaptation between the jump interpositional nerve graft and hypoglossal nerve: Outcome and duration of preoperative paralysis.

Background: In this report, we described the use of hypoglossal-facial neurorrhaphy with end-to-side coaptation between the jump interpositional nerve graft and the hypoglossal nerve for facial reanimation and analyzed the relationship between the outcome of surgery and duration of preoperative paralysis.

Methods: We performed hypoglossal-facial neurorrhaphy with the jump interpositional nerve graft on nine men and 10 women with unilateral complete facial paralysis. The patients, with a mean age of 39.

Study of continuous irrigation negative-pressure treatment using an original ulceration model.

A continuous irrigation with intermittent aspiration (CIIA) method has previously been developed in the treatment of infected expander sites. For the purpose of treatment of infected wounds, a new intermittent negative pressure irrigation treatment (INPIT) has been developed that is a combination of CIIA with topical negative-pressure therapy. This study aims to investigate the efficacy of INPIT.

How to reconstruct a natural and deep umbilicus: three methods of umbilicoplasty for five types of umbilical deformities.

Unlabelled: Conventional methods of umbilicoplasty using V-Y advancement flap often result in unnatural wide or shallow umbilical depressions facing upward or downward. Moreover, although the umbilical deformities have many variations, no report has described the selection of an umbilicoplasty method for types of umbilical deformity. To resolve these problems, we devised 3 methods of umbilicoplasty.

Accumlation of lipoprostaglandin E1 at the anastomotic region after systemic application.

Lipoprostaglandin E1 (lipo-PGE1) has been found accumulating in injured vascular regions. This study examined the localization of lipo-PGE1 in the anastomotic region. The study was divided into three parts.

A modified technique for hepatic artery reconstruction in living donor liver transplantation.

Reconstruction of the hepatic artery (HA) is challenging, because there are technical difficulties. Especially, it is difficult to repair the posterior wall. In 2006, we reported an experimental study of the posterior wall first continuous suturing combined with the interrupted suturing and we also confirmed the safety of this procedure.

Aesthetic repair for syndactyly of the toes using a plantar rectangular flap.

Background: Use of a dorsal rectangular flap is the most common method of creating a deep interdigital space for syndactyly of the toes. However, the pigmented skin grafts exposed to the dorsal side are conspicuous. To resolve this problem, several methods have been reported.

Free flap failure in an anticardiolipin antibody-positive patient with neoplasm--a case report.

We present herein a case of massive arterial thrombosis of a free rectus abdominal musculocutaneous flap used for reconstructive surgery of gingival carcinoma that could not be rescued. A 54-year-old woman underwent the operation. She had experienced two miscarriages in her 20s, but medical history was otherwise uneventful.

Three-step orbitofacial reconstruction after extended total maxillectomy using free RAM flap and expanded cervicofacial flap with cartilage grafts.

Facial defect after an extended total maxillectomy is one of the most difficult deformities to reconstruct aesthetically, because the defect is not only large but also three-dimensional. Although free-flap reconstruction is useful, the patchwork-like scar, bad colour match and poor texture match are major problems. The contracture and displacement of the reconstructed eyelids and eye socket are also serious matters.

Surgical repair of transverse facial cleft: oblique vermilion-mucosa incision.

Various surgical techniques have been reported for the repair of the transverse facial cleft using a straight-line closure, Z- or W-plasty, local flaps, etc. However, several problems remain such as deviation, distortion and scars in the commissure and cheek. To resolve these problems, we studied the anatomy of the commissure again and devised the most reasonable method for repair of the transverse facial cleft.
