Ectopic spleen in pelvis minor--a case report]

A case of ectopic spleen diagnosed as a left adnexal tumor in a 19 year old female was presented. Considering the rareness and lack of typical symptoms, diagnosis of this pathology still is very difficult, and establish most often intraoperatively. In every case of ascertainment irregular mass in minor pelvis one should differentiate it among: colonic diverticulosis, wandering kidney, coproliths, colon and mesentery tumors and ectopic spleen. We consider that ultrasonography plays the special role in these cases. In every case of stating the pathologic structure in minor pelvis it seems advisable not to content only with estimation of genital organs, but also locate such as: kidneys, liver, spleen. Such a procedure allows to state preoperative diagnosis more precisely.     

Atlanto-axial rotatory fixation: Improved demonstration using spiral CT

Atlanto-axial rotatory fixation (AARF) is an uncommon condition which is often missed at presentation because of its rarity and the relative subtlety of plain film X-ray findings, but early detection and appropriate management are vital for a cure. We describe three cases in which the use of spiral computed tomography scanning with 3D and sagittal reconstructions greatly aided diagnosis and management. The 3D images gave a more graphic picture of the overall alignment of the upper cervical spine and the skull base, while the sagittal reconstructions demonstrated the presence or absence of compensatory atlanto-occipital subluxation. The literature is briefly reviewed.     

Assessment of routine elimination of postoperative nasogastric decompression after Roux-en-Y gastric bypass

BACKGROUND: Anastomotic disruption after surgical intervention is an infrequent complication, but may lead to severe morbidity and mortality when it occurs. Of the various gastric procedures, the Roux-en-Y gastric bypass (RYGB) has one of the highest risks for anastomotic leakage. Consequently, a nasogastric tube (NGT) is frequently placed when these operations are performed. Most studies examining the outcomes for patients without postoperative NGTs have been relatively small with groups of patients undergoing a variety of operations. Assessing the incidence of anastomotic leaks by routine elimination of postoperative NGTs requires a large number of patients. In this study, we assessed the safety and efficacy of routine elimination of NGTs in a large cohort of patients undergoing a single operation. METHODS: We reviewed our experience with 1067 patients who underwent RYGB at the UCLA medical center. Fifty-six patients had NGTs routinely placed before the implementation of a standard protocol, which eliminated postoperative NGT decompression. The complication rate for the RYGB patient cohort with and without postoperative NGT was compared. RESULTS:We found no difference in the complication rates between the 2 groups (Fisher exact test; P =.21). CONCLUSIONS: Our findings suggest that routine placement of an NGT after RYGB is unnecessary.
