M Seguel, F Muñoz, M J Navarrete, E Paredes, E Howerth, N Gottdenker
Tissues of South American fur seal pups naturally infected with hookworms ( Uncinaria sp) were examined. Hookworm infection was found in nearly all pups examined (132/140, 94%), and hookworm enteritis with secondary bacteremia was considered the cause of death in 46 (35%) pups. Common findings in these pups included severe hemorrhagic enteritis and numerous (mean intensity = 761.8) hookworms in the jejunum. Hookworms were recovered from the abdominal cavity in 12 of 55 pups (22%) examined through peritoneal wash; these pups had an average of 1343...

Iatrogenic aortic dissection (AD) is quite a rare complication during percutaneous coronary intervention (PCI). The exact mechanism of iatrogenic AD during PCI is unknown. A standard of care in the management of iatrogenic AD is still lacking. We describe a case of an 83-year-old man, with an aortocoronary bypass graft, who underwent complex PCI with rotational atherectomy catheterization with a radial approach for a chronic right coronary artery stenosis, complicated by AD. According to our experience, retrograde dissection into the aorta during PCI can be sealed with a coronary stent that covers the coronary ostium and should be treated conservatively in most circumstances, unless complication like extension of dissection into other vessels or pericardial effusion or hemodynamic instability occurs...

BACKGROUND: Operative clips used to ligate vessels in abdominal operation usually are made of titanium. They remain in the body permanently and form metallic artifacts in computed tomography images, which impair accurate diagnosis. Although biodegradable magnesium instruments have been developed in other fields, the physical properties necessary for operative clips differ from those of other instruments. We developed a biodegradable magnesium-zinc-calcium alloy clip with good biologic compatibility and enough clamping capability as an operative clip...

BACKGROUND: The sealing and transection of mesenteric vessels is a crucial step in minimally invasive colorectal surgery. We examined the sealing quality of the ENSEAL(®) G2 Articulating Tissue Sealer in three different articulations in mesenteric vessels. METHODS: This was a prospective experimental study within a tertiary healthcare center, and 30 patients were recruited. Burst pressures for each specimen were measured as the primary outcome. Ten specimens at each of the three articulations were also histologically assessed for the quality of seal...

BACKGROUND: Nephron-sparing surgery in the form of partial nephrectomy is increasingly becoming the standard of care in patients with small renal tumours. Oncological outcomes for partial nephrectomy are equivalent to radical nephrectomy, however, clamping of the hilar vessels to allow resection of tumours during partial nephrectomy may cause ischaemic damage to the kidney and result in long-term renal impairment. AIM: We carried out a retrospective review of 43 patients undergoing laparoscopic partial nephrectomy (LPN) and assessed functional and oncological outcomes...

Subclavian artery (SCA) perforation is a rare complication while performing SCA intervention. In our present report, a 73-year-old female, with stenosis of the left SCA and situs inversus, presented with exercise-induced left arm weakness. The SCA stenosis was treated with direct stenting with a balloon-expansible Express LD 10×25 mm stent. However, it caused iatrogenic SCA perforation and hemothorax. The perforation was sealed by endovascular repair with operator-modified Endurant II graft stent, which complicated with occlusion of left common carotid artery...

The objectives of this study were to compare (1) the extent of thermal damage and (2) the time between the 5-mm LigaSure V (LS5) and 10-mm LigaSure Atlas (LS10) vessel sealing devices (VSD) when performing open ovariectomy in dogs. A prospective, randomised, clinical trial was performed in 40 client-owned sexually entire female dogs. In each dog, one ovary was randomly assigned to be surgically removed using LS5 and the contralateral using LS10. The depth of thermal spread, measured on histopathological preparations, was significantly larger for LS10 (LS10 1...

The human circulatory system comprises a complex network of blood vessels interconnecting biologically relevant organs and a heart driving blood recirculation throughout this system. Recreating this system in vitro would act as a bridge between organ-on-a-chip and "body-on-a-chip" and advance the development of in vitro models. Here, we present a microfluidic circulatory system integrated with an on-chip pressure sensor to closely mimic human systemic circulation in vitro. A cardiac-like on-chip pumping system is incorporated in the device...

BACKGROUND: Laparoscopic sleeve gastrectomy (SG) as a single-stage procedure for the treatment of morbid obesity is becoming increasingly popular. In undeveloped countries, the linear staples required to create the sleeve are not always available because of their high cost. As an alternative to the staples, the bipolar vessel sealer device could be used in bariatric surgery to divide and temporarily seal the stomach.

BACKGROUND: Newer generation devices have attempted to accommodate a wider range of aortoiliac anatomies offering endovascular aneurysm repair (EVAR) to more patients with abdominal aortic aneurysms (AAAs). We aim to examine the anatomic suitability for the ultra-low profile Ovation endograft in our AAA patients and to compare them with other contemporary devices. METHODS: 158 consecutive AAA patients treated with EVAR or open surgical repair (OSR) were tested for EVAR eligibility according to the most commonly used endografts' instructions for use...

Introduction: In the treatment of complex aneurysms, debranching is an extra-anatomical revascularization of visceral arteries followed by endograft coverage of the thoracoabdominal aorta. It eliminates the need for a thoracotomy and aortic clamping, but requires the performance of several technically demanding visceral anastomosis. In 2008, Lachat described visceral revascularization with the use of a sutureless distal anastomosis, performed by the telescoping of an endograft in the visceral branch, named VORTEC (Viabahn Open Revascularization TEChnique)...

INTRODUCTION: Laparoscopic hepatectomy is difficult because surgeons must perform the transection using many (four and more) energy devices and without direct manual maneuvers. Here we introduce hepatic transection by the classical method with a few (two or three) energy devices. MATERIALS AND SURGICAL TECHNIQUE: We performed laparoscopic hepatectomy for 40 patients with hepatic tumor and liver dysfunction. For parenchymal transection, we used bipolar radiofrequency coagulation forceps connected to a voltage-controlled electrosurgical generator and ultrasonic dissector...

Transumbilical laparoscopic assisted appendectomy combines laparoscopic single port dissection with open appendectomy after exteriorization of the appendix through the port site. Compared to the conventional three-port approach, this technique provides an alternative with excellent cosmetic outcome. We developed a safe and effective technique to perform an intracorporeal single port appendectomy, using the same laparoscope employed in the extracorporeal procedure. Retrospective review of 71 consecutively performed intracorporeal single port appendectomies and 30 conventional three-port appendectomies in children 6 to 17 years of age...

OBJECTIVE: The natural history of type II endoleak (T2EL) after endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA) remains elusive; as such, treatment guidelines are ill defined. The purpose of this study was to better delineate the natural history of T2EL after EVAR for rAAA in an effort to determine the need for reintervention and optimal surveillance. METHODS: A retrospective record review was conducted of all patients undergoing EVAR for rAAA in two large tertiary care academic vascular centers...
