since co2 pneumoperitoneum is the dominant method of laparoscopic exposure due to facility and good view, its physiologic effects are most relevant to the surgeons. co2 pneumoperitoneum may affects hemodynamics by increased intra-abdominal pressure (iap) and the physiologic effects of absorbed co2. the adverse effects of both mechanisms relate directly to the duration of the pneumoperitoneum an...

OBJECT The thoracolumbar junction (T11-L2) poses an anatomical dilemma, given the presence of the lower rib cage and the diaphragm when performing anterolateral approaches. To circumvent dealing with the diaphragm, a minimally invasive lateral extracoelomic approach has been used to approach the thoracolumbar junction by mobilizing the diaphragm anteriorly. No anatomical studies have described ...

Abstract Background: Obesity is a chronic condition with high prevalence and multifaceted etiologies; it accompanied by an increased risk of morbidity mortality. Bariatric surgeries (weight loss surgeries) include variety procedures performed on people who have obesity. Skin redundancy common post-bariatric complication. Abdominoplasty or "tummy tuck" cosmetic surgery procedure used to make the...

abdominal wall hernias are common problems found in patients with cirrhosis because of persistently high intra-abdominal pressure. when abdominal hernias are neglected in such patients, they may become larger and could result in cosmetic problems and pressure effects that are also difficult to treat. we found a voluminous mass in the anterior abdominal wall of a 40-year-old patient with cirrhos...

Figure 1. Top, An abdominal CT scan with contrast enhancement demonstrates a liver abscess at the lateral segment of the left hepatic lobe, with a linear fish bone (arrow) visible within the abscess. Bottom, A non–contrast-enhanced CT scan in oblique coronal reformation demonstrated that the fish bone was retained in the liver without any sequelae. prolonged courses of oral artesunate to our pa...

Flank and lateral abdominal wall defects can be an extremely challenging phenomenon for surgeons to undertake. Their rarity and specific idiosyncrasies in regard to embryologic and anatomical characteristics must be taken into consideration when formulating an operative plan. We will discuss these cardinal points including technical recommendations by notable experts in the field to gain a bett...

This study provides a reference for the radiographic anatomy of the thoraco-abdominal cavity of female ostriches as a representative of ratites. One ostrich cadaver, 2 adult and 2 growing ostriches were used. Right lateral radiographs produced by a 6-frame technique and 2 dorsoventral radiographs produced by an adapted 3-frame technique were selected and schematic illustrations of these were la...

INTRODUCTION Even the half of patients undergoing laparoscopic adrenalectomy has history of previous abdominal surgeries. However, it is still uncertain if this fact has an impact on the operation itself as well as the postoperative course. AIM To analyze the effects of previous abdominal surgery on surgical outcomes in adrenal tumor patients subjected to laparoscopic adrenalectomy. MATERIA...

Heartbeat activity in tethered adult drosophilids was recorded using a linear optosensor chip and an IR-light beam. Recording from two to five sensor elements within 250 mum along the anterior heart, it was possible to analyze periodic reversals. In intact Drosophila melanogaster and D. hydei, longer anterograde pulse periods with lower pulse rates generally alternated with shorter retrograde p...

BACKGROUND Intra-abdominal desmoid tumors are usually slow growing and solitary, but multifocal desmoid tumors develop on rare occasions. Diagnosing desmoid tumors before histological examination of a surgical biopsy is often difficult. In particular, if a patient has a prior history of malignancy, it may be difficult to differentiate between these lesions and disease recurrence or metastasis. ...
