Infective abdominal aortic aneurysm (IAAA) is relatively rare, but a case which is caused by Haemophilus influenzae type B is very rare. We experienced one IAAA case due to H. influenzae type B. The patient was 69-year-old man presenting with severe abdominal and back pain and elevated C-reactive protein (CRP), as inflammatory marker. The patient was found to have saccular aneurysm infrarenal aorta on computed tomography scanning. First, we started to treat him with antibiotic agent and second, we operated him at day 8 after admission with expanded polytetrafluoroethylene graft. Revascularization was made in situ reconstruction. As the result of culture with aneurysm wall, we found that the cause of this aneurysm was the infection of H. influenzae type B. As far as we know, this bacterium is scarcely reported as the cause of infective aortic aneurysms. We reported this IAAA case with the review of the English literature.

Uterus-like mass composed of a cavity lined by mucosa resembling endometrium and surrounding smooth muscle layer simulating myometrium is an extremely rare disease entity of which the histogenesis is presently unknown. A 39-year-old, gravida 2, para 2, woman presented with sudden onset of lower abdominal pain and was found to have left adnexal mass with unusual image diagnostic appearance. The adnexal mass arising from the left ovarian ligament was excised by laparoendoscopic single-site surgery. Histopathological diagnosis was uterus-like mass of ovarian ligament. © 2011 The Authors.

Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant hereditary disorder that develops multiple tumors arising from various endocrine organs, including the parathyroid gland, endocrine pancreas and pituitary gland. Although mesenchymal tumors can be an integral part of the syndrome, parasitic peritoneal myomas have never been described in an MEN1 patient. Seven years after laparoscopic-assisted myomectomy, parasitic peritoneal myomas were diagnosed in a 31-year-old woman with situs inversus totalis and previous history of parathyroid adenoma. Subsequently, MEN1 was clinically diagnosed by identification of endocrine pancreatic, adrenal and pituitary tumors. Genetic analysis revealed a heterozygous germline mutation in the splice donor sequence of intron 6 of the MEN1 gene. Although rare, parasitic peritoneal myomas could potentially be associated with MEN1 syndrome. © 2013 The Authors. Source

Objective Uterine artery pseudoaneurysm is a rare potentially life-threatening complication after myomectomy. Its clinical characteristics and management, and the outcomes of subsequent pregnancy, are not well understood. The purpose of this study was to clarify these important issues. Study design Retrospective analysis of a case series of uterine artery pseudoaneurysm detected after laparoscopic-assisted myomectomy (LAM) in a single center over a 13-year period. During the early postoperative course, gray scale ultrasonographic evaluation was carried out routinely by searching for an anechoic or hypoechoic well-defined cystic structure in the post-myomectomy scar. In suspicious cases, further evaluation was performed by color Doppler flow analysis and three-dimensional computerized tomographic angiography. After finally confirming the diagnosis by digital subtraction angiography, uterine artery pseudoaneurysm was conservatively managed by angiographic intervention. In cases achieving successful conception, cesarean delivery was chosen and the uterine scar was evaluated. Results Uterine artery pseudoaneurysm was diagnosed in 9 out of 854 cases of LAM. One case was undiagnosed until massive uterine hemorrhage occurred in the late postoperative period, while the other eight cases were diagnosed in the early postoperative course without hemorrhagic complication. Eight cases were managed by uterine artery embolization, but spontaneous resolution of pseudoaneurysm was observed in one case during a difficult prolonged attempt to superselect the offending branch of the uterine artery. Postembolization course was uneventful, except in a 41-year-old woman who developed oligomenorrhea. Among five women desiring preserved fertility, three women including one after spontaneous miscarriage achieved live birth by cesarean section. One woman experienced spontaneous miscarriage and one did not become pregnant by fertility treatment. In a case with elective cesarean delivery, severe early postpartum hemorrhage occurred from the placental bed and was conservatively managed by emergency uterine artery embolization. Conclusion The development of uterine artery pseudoaneurysm after myomectomy may be more common than previously considered, and should be carefully monitored to avoid potentially life-threatening hemorrhage and loss of fertility. Although spontaneous resolution may occur, conservative management by angiographic intervention could be a feasible management option for future fertility preservation, once a diagnosis has been made. © 2014 Elsevier Ltd.

Objective: To evaluate the safety and feasibility of gasless transumbilical laparoendoscopic single-site (LESS) surgery for the management of adnexal masses in pediatric and adolescent girls aged 19 years or younger.Study design: Retrospective study of 28 pediatric and adolescent girls each undergoing gasless LESS surgery and gasless multiport laparoscopic surgery for adnexal masses. In each case, laparoscopic surgery was performed by the abdominal-wall lift method under endotracheal general anesthesia. The two groups were compared for their patient demographics and surgical outcome measures.Results: In the LESS surgery group, median age of the patients including three pre-menarcheal girls was 17.5 years. The most common symptom was abdominal pain. Median tumor diameter in the LESS surgery group was 7.4 cm. There were no statistical differences in clinical features between LESS surgery and multiport laparoscopic surgery groups. In the LESS surgery group, adnexal masses were managed by unilateral cystectomy (n = 20), unilateral salpingo-oophorectomy (n = 5), bilateral cystectomy (n = 2), and unilateral salpingectomy (n = 1). Emergency LESS surgery was performed for seven cases due to adnexal torsion and one case due to cyst rupture. Preservation of affected ovary was not achieved in three emergency cases with adnexal torsion due to severe necrosis, and in one case each of recurrent mucinous cystadenoma and huge mucinous cystadenoma. In 24 adnexal masses from 22 girls who received adnexal cystectomy by LESS surgery, LESS-assisted extracorporeal cystectomy, was possible in 14 masses while intracorporeal cystectomy was required in other 10. In a case of dermoid cyst managed by LESS-assisted extracorporeal cystectomy, additional hemostasis was required by intracorporeal suturing due to laceration of utero-ovarian ligament. Median-excised tissue weight in the LESS surgery group was 111 g. Significant differences between LESS surgery and multiport laparoscopic surgery groups were not noted in surgical outcomes and pathological diagnosis, except for significantly lower C-reactive protein value on postoperative day 3 in the LESS surgery group.Conclusion: Gasless LESS surgery for pediatric and adolescent adnexal masses is a safe and feasible alternative to multiport laparoscopic surgery. © 2014 Elsevier Ireland Ltd.
