Inadvertent spillage of gall stones is a rare yet important cause of delayed postcholecystectomy complications. Varied presentations and difficulty in diagnosis are the hallmarks, making it crucial to have a high index of suspicion to detect and intervene appropriately. Peritoneo-cutaneous fistulae from the retained stone can be completely excised in toto.

Esophagectomy followed by intrathoracic anastomosis is threatened by leakage which may prove all the more serious that mediastinal contamination is extensive. In the technique presented, the esogastric anastomosis is slipped under the upper mediastinal pleura which is kept intact, after the azygos vein has been ligated and divided. This pleural 'blanket' may act as an efficient barrier against ...

BACKGROUND The purpose of this study is to find the optimal planning settings for prostate SABR-VMAT for high-risk prostate cancer patients irradiated to prostate only (PO) or prostate and pelvic lymph nodes (PPLN). METHODS For 10 patients, plans using 6MV flattened, flattening-filter-free (FFF) 6MV (6 F) and FFF 10MV (10 F) photon beams with full and partial arc arrangements were generated a...

We consider the problem of aligned coloring of interval and chordal graphs. These problems have substantial applications to register allocation in compilers and have recently been proven NP-Hard. We provide the first constant approximations: a 4 3 -approximation for interval graphs and a 3 2 -approximation for chordal graphs. We extend our techniques to the problem of minimizing spillage in the...

Although the above-cited measurements were done in vitro, the results are applicable in vivo because the processes are based on simple laws of physics. They are also corroborated by clinical observations. Increased aPTT has been reported when samples were taken shortly after locking [6–8] . The low gentamicin concentration measured by Zhang et al. prior to the next treatment does not reflect th...
