RESUMO

We herein report a case of refractory lymphatic ascites after uterine cancer surgery treated with bilateral inguinal lymphaticovenular anastomosis (LVA). LVA was performed four months after the uterine cancer surgery in a patient with refractory ascites that had developed one month after the gynecologic surgery. One year and eight months after LVA, there was no recurrence of ascites accumulation.

RESUMO

BACKGROUND: An artificial nerve conduit can interpose the peripheral nerve defect without donor site morbidity. However, treatment outcomes are often unsatisfactory. Human amniotic membrane (HAM) wrapping has been reported to promote peripheral nerve regeneration. We evaluated the effects of a combined application of fresh HAM wrapping and a polyglycolic acid tube filled with collagen (PGA-c) in a rat sciatic nerve 8-mm defect model. METHODS: The rats were divided into three groups: (1) the PGA-c group (n = 5), in which the gap was interposed with the PGA-c; (2) the PGA-c/HAM group (n = 5), in which the gap was interposed with the PGA-c bridge, then HAM (14 × 7 mm) was wrapped around it; and (3) the Sham group (n = 5). Walking-Track recovery, electromyographic recovery, and histological recovery of the regenerated nerve were evaluated at 12 weeks postoperatively. RESULTS: Compared to the PGA-c group, the PGA-c/HAM group showed significantly better recovery in terminal latency (3.4 ± 0.31 ms vs. 6.6 ± 0.72 ms, p < 0.001), compound muscle action potential (0.19 ± 0.025 mV vs. 0.072 ± 0.027 mV, p < 0.01), myelinated axon perimeter (15 ± 1.3 µm vs. 8.7 ± 0.63 µm, p < 0.01), and g-ratio (0.69 ± 0.0089 vs. 0.78 ± 0.014, p < 0.001). CONCLUSION: This combined application highly promotes peripheral nerve regeneration and may be more useful than PGA-c alone.

RESUMO

We herein report three cases of obturator nerve injury, which is rare in gynecological surgery. In all cases, it was difficult to suture both nerve ends without tension. Therefore, we used a PGA-collagen tube to interpose the nerve defect. After follow-ups of at least seven months, all three patients were able to adduct the hip joint and medial thigh sensations also improved. These results suggest the potential of a PGA-collagen tube in the treatment of obturator nerve injury.

RESUMO

Background: The scrotum functions to maintain spermatogenesis and hormonal production of Leydig cells by preventing the testicles from rising in temperature and protecting them from the outside world. The scrotum, along with the penis, is also an organ that symbolizes masculinity. Therefore, deformity or loss of the scrotum can be a major psychological problem. Various scrotal reconstruction techniques have been reported. In these papers, there is some discussion about the type of skin flap, but little discussion about the method of suturing the skin flap. We devised a way to reconstruct a scrotum to a natural size by suturing two skin flaps together to form a ball shape. Case Presentation. Case 1 was a patient with a missing scrotum due to Fournier's gangrene. Total resection of the scrotum, including the bilateral testes, was performed to save his life. Reconstructive surgery was performed 11 days after the initial surgery. Reconstruction was performed using bilateral gluteal fold flaps. Case 2 was a patient with a congenital defect of the scrotum. The testis on the right side exhibited cryptorchidism, and the scrotum was missing, and the testis on the left side was encased in a hypoplastic scrotum. Reconstruction was performed using an internal pudendal artery perforator flap. Conclusion: There are two types of scrotal defects: those with testes present and those with testes missing. This method can be used for both types of scrotal defects, and we were able to create a scrotum that satisfied each patient.

RESUMO

ABSTRACT: Percutaneous and transconjunctival approaches are commonly used for fractures of the orbit and orbital rim. However, it leaves visible scarring on the face. Although previous studies reported scarring from the percutaneous approach, few reported the degree of such scarring. The authors examined the degree of scarring associated with percutaneous approaches to fractures of the orbit and orbital rim in the Japanese population. The authors reviewed photographs of patients who were treated surgically for fractures of the orbital floor, medial orbital wall, or zygomatic bone via percutaneous approaches to examine the presence of scarring and deformation. In 36% of all patients, the observers were unable to determine the side on which the surgery was performed. Furthermore, the site of scarring was identified accurately in only 20.6% of the cases in which observers were able to identify the surgical side. The authors' study demonstrated that the subciliary approach left minimal scarring under the eyelashes. On the other hand, the medial canthal approach left depressed and wide scarring, whereas pigmentation was apparent in patients who underwent surgery via the lateral eyebrow approach. Similarly, pigmentation under the eyelashes and at the site of secondary incision was common after the subciliary approach.

RESUMO

The treatment of postaxial polydactyly requires excision of the medial fifth or lateral sixth toe, and separation of the adjacent fourth/fifth toes if the adjacent toes exhibit skin syndactyly. Morphological changes in the retained toes and reoperation are common problems after such surgery. This study examined the effects of preoperative classifications and selecting the medial fifth or lateral sixth toe for excision on the postoperative outcomes of surgery for postaxial polydactyly. From April 2006 to March 2019, surgery for postaxial polydactyly was performed on 55 feet in 49 patients. The patients' mean age at surgery was 28.8 months. Postoperative esthetic and bone alignment scores, the reoperation rate, and postoperative dysfunction were examined. The postoperative esthetic and bone alignment evaluations were performed by examining postoperative photograph and X-ray images using original scoring systems. The surgical procedure was chosen by the surgeon-in-charge during a preoperative conference after considering the toe growth and bone alignment. In the postoperative esthetic evaluation, excising the lateral sixth toe produced significantly better outcomes than excising the medial fifth toe. The morphological classification also indicated that excising the lateral sixth toe produced better outcomes, as it resulted in the bifurcated toes being clearly independent. Interestingly, the postoperative X-ray-based bone alignment score was not correlated with the esthetic score. The reoperation rate tended to be high after medial fifth toe excision. There were no postoperative functional complications. Lateral sixth toe excision for postaxial polydactyly of the foot produces good postoperative esthetic outcomes.

RESUMO

We herein report a case of intractable flexor tenosynovitis. The inflamed synovium was debrided twice because of suspected infectious tenosynovitis. However, it relapsed and caused a soft tissue defect. Reconstruction with a free temporoparietal fascia (TPF) flap was performed. Recurrence has not been detected in the six years after surgery.

RESUMO

A regrowing nail tip after nail avulsion may excessively curve and invaginate into the nail bed. This is treated as a type of ingrown toenail, and is known as distal nail embedding. In most cases, further growth restores the original shape evenly over the nail bed. However, it is often painful and such cases may require treatment. We report a surgical approach that we applied to six cases of distal nail embedding involving pain or deformity of nails caused by a nail tip invaginating into the nail bed and/or cessation of forward nail growth. As our method involves removing a portion of the embedded tip edge nail and inserting the removed nail into the remaining depressed portion, the nail can grow over the bulge. In all six patients in whom we applied this method, the pain and nail deformity resolved and there was no recurrence. We used autogenous nails, which can reduce the pressure imbalance on a nail bed, and this contributed to improving the morphology of nails and nail beds. In addition, the risk of a hypertrophied nail is reduced because half of the nail adheres to the nail bed. Special materials are unnecessary and this method can be conducted with simple outpatient department procedures. There were no cases of a fixed nail section detaching due to a bulge at the nail tip. The inserted nail was maintained in all cases for several months until the nail grew over the bulge.

RESUMO

Hepatocellular carcinoma accompanied by portal hypertension and hypersplenism is difficult to treat medically and surgically due to pancytopenia and the development of collateral circulation. In this study, we were able to safely and simultaneously perform a laparoscopically-assisted splenectomy and partial hepatectomy. The characteristics of this procedure include: (1) the shared use of a medial wound made through laparoscopically-assisted surgery; (2) improved safety for manipulating areas that were difficult to observe with a camera in a case of splenomegaly; (3) a preventive ligation of the splenic artery; (4) improved hemostatic function using LigaSure Impact; and (5) hemorrhage control through manual manipulations and the Pringle maneuver during liver parenchymal transection. The surgery was safely performed using the above points.

RESUMO

There is increasing evidence that cancers contain their own stem-like cells called cancer stem cells (CSCs). A small subset of cells, termed side population (SP), has been identified using flow cytometric analysis. The SP cells have the ability to exclude the DNA binding dye, Hoechst33342, and are highly enriched for stem cells in many kinds of normal tissues. Because CSCs are thought to be drug resistant, SP cells in cancers might contain CSCs. We initially examined the presence of SP cells in several human thyroid cancer cell lines. A small percentage of SP cells were found in ARO (0.25%), FRO (0.1%), NPA (0.06%), and WRO (0.02%) cells but not TPC1 cells. After sorting, the SP cells generated both SP and non-SP cells in culture. The clonogenic ability of SP cells was significantly higher than that of non-SP cells. Moreover, the SP prevalence was dependent on cell density in culture, suggesting that SP cells preferentially survived at lower cell density. Microarray experiment revealed differential gene expression profile between SP and non-SP cells, and several genes related to stemness were up-regulated. However, non-SP population also contained cells that were tumorigenic in nude mice, and non-SP cells generated a small number of SP cells. These results suggest that cancer stem-like cells are partly, but not exclusively, enriched in SP population. Clarifying the key tumorigenic population might contribute to the establishment of a novel therapy for thyroid cancer.
