Background: The aim of this study was to assess the impact of inferior mesenteric artery (IMA) root nodal dissection before high ligation of the artery on survival in patients with sigmoid colon or rectal cancer. Methods: Data on 1188 consecutive patients who underwent resection for sigmoid colon or rectal cancer, with high ligation of the IMA, were identified from a prospective database (April 1965 to December 1999). Survival of patients with involvement of nodes along the IMA proximal to the origin of the left colic artery (root nodes, station 253) through the bifurcation of the superior rectal artery (trunk nodes, station 252) was determined. Results: Twenty patients (1·7 per cent) had metastatic involvement of station 253 lymph nodes and 99 (8·3 per cent) had metastases to station 252. The 5- and 10-year survival rates of patients with metastases to station 253 were 40 and 21 per cent, and those for patients with metastases to station 252 were 50 and 35 per cent, respectively. Conclusion: High ligation of the IMA allows curative resection and long-term survival in patients with cancer of the sigmoid colon or rectum and nodal metastases at the origin of the IMA.

Visualized Sclerotherapy of Varicose Veins

DERMATOLOGIC SURGERY, Issue 2010
MAMORU KIKUCHI MD
BACKGROUND The spread and movement of sclerosant after injection during sclerotherapy is difficult to monitor. OBJECTIVE To develop a new visualization method that allows monitoring of sclerosant dosage and flow during sclerotherapy. METHODS We used a photodynamic eye (PDE) to perform indocyanine green (ICG) imaging. ICG produces strong fluorescence detectable using PDE and allows monitoring of sclerosant spread through blood vessels in real time. We performed visualized sclerotherapy on 50 limbs, comprising high ligation and sclerotherapy (35 limbs), stripping and sclerotherapy (10 limbs), and sclerotherapy alone (5 limbs). RESULTS In all cases, fluorescence imaging of the injected sclerosant was possible. No complications resulted from combining ICG and polidocanol in any of the patients, all of whom received follow-up evaluations at 1 week, 1 month, and 3 months after treatment. CONCLUSIONS Our new method not only avoids the risk of radiation exposure, but also allows for simple observation of sclerosant range of access, determination of the dosage for each lesion, and accurate administration of therapy to target lesions. This method will contribute to further advances in sclerotherapy, given that it allows administration of sclerosant and visual confirmation of optimal injection dosage, speed, and movement of sclerosant after injection. The authors have indicated no significant interest with commercial supporters. [source]

Surgical Excision of Pedunculated Supernumerary Digits Prevents Traumatic Amputation Neuromas

PEDIATRIC DERMATOLOGY, Issue 2 2003
Geoffrey E. Leber
The first group consisted of three patients who had among them five traumatic amputation neuromas. In each case these lesions resulted from primary suture ligation of accessory digits in infancy. Secondary surgical excision of the vestigial digit with high ligation and retraction of the accompanying nerve tissue was required in all cases. The second group consisted of six patients who had 12 pedunculated supernumerary digits. Primary surgical excision of these digits was performed with high transection and retraction of the accompanying accessory digital nerve. All patients in this group had excellent cosmetic results with no postoperative neuroma formation. Adult family members who had undergone suture ligation of similar supernumerary digits in infancy accompanied seven of the nine patients in this series. On careful examination, each of these family members had signs and symptoms attributable to traumatic amputation neuromas. We feel identification and high transection of the accessory digital nerve is essential in the treatment of pedunculated supernumerary digits. This treatment prevents traumatic amputation neuromas and yields a better cosmetic result than the traditional method of suture ligation in infancy. [source]

Polyorchidism: a three-case report and review of the literature

ANDROLOGIA, Issue 1 2010
M. Savas
Summary The presence of more than two testes confirmed by histology is called polyorchidism. Polyorchidism is an extremely rare congenital anomaly with a few more than 100 cases reported in the literature. The majority of reported cases are asymptomatic patients, others present with cryptorchidism, hydrocele, varicocele, epididymitis, infertility, testicular malignancy and testicular torsion. Over a 2-year period, we encountered three patients who were found to have polyorchidism; two men presented with cryptorchidism and one with chronic scrotal pain. Physical examination of the first and the third patient revealed normal testes in the scrotal sac, the other scrotal sac was empty and small solid mass (atrophic left testes) was palpated in the inguinal canal. Ultrasonographic examination of the scrotum and inguinal region confirmed the findings of the physical examination. Ultrasonographic examination of the second patient revealed supernumerary testes within the scrotum. Orchiectomy was made on the first and third patients' supernumerary testes and ipsilateral inguinal high ligation was applied for herniorrhaphy. A conservative approach was preferred for the second patient, maybe preserving a potentially functional supernumerary testis to improve the capacity for spermatogenesis. The risk of malignancy justifies the removal of an atrophic and ectopic testis in polyorchidism. However, it would appear safe to preserve a viable intrascrotal supernumerary testis found incidentally at surgery, provided that the patient is followed-up in the long term. [source]

Sperm ultramorphology as a pathophysiological indicator of spermatogenesis in males suffering from varicocele

ANDROLOGIA, Issue 3 2000
M. Reichart
Summary. Varicocele of spermatic veins is considered to be one of the major causes of male infertility associated with reduction of sperm quality. The pathophysiology of this condition is not yet completely understood. The aim of this study was to shed light on the pathophysiology of varicocele by identifying semen parameters, especially sperm ultramorphology, which improve following high ligation of the spermatic vein. Seventy-five males with diagnosed varicocele were included in this study. Semen parameters were assessed prospectively using light microscopy, semen biochemistry and sperm quantitative ultramorphological analysis, before high ligation and 3,9 months after high ligation. The control group consisted of twenty-five untreated varicocele patients who underwent two semen examinations within 3,9 months. No statistical difference in any of the examined variables was found between the two examinations in the control group. The treated patients exhibited a significant improvement in sperm density, progressive motility, percentage of normally formed spermatozoa, agenesis of sperm acrosome, chromatin condensation and incidence of amorphous heads compared with the pretreatment condition (P,0.01). In contradiction, no significant improvement was observed following treatment in any of the sperm tail subcellular organelles. It is concluded that varicocele may cause deleterious alterations in early spermatid head differentiation during spermiogenesis and that varicocele patients with a high incidence of sperm acrosome and nucleus malformations are appropriate candidates for varicocele correction.
