Overall, injury severity, severity of renal injury grade, hemodynamic instability, and transfusion requirements are predictive of nephrectomy after both blunt and penetrating trauma. Nephrectomy is more likely after penetrating injury.

Spinal anesthesia with supplemental epidural clonidine in combination with incision site subcutaneous bupivacaine was evaluated both intra- and postoperatively and compared with spinal anesthesia alone for lower lumbar spine procedures. Both epidural clonidine and subcutaneous incisional bupivacaine, added to spinal anesthesia for lumbar spine surgery, improves pain relief and reduces the need for postoperative opioids with their associated side effects.

Background: The purpose of our study was to assess the impact of distal margin length on outcome in patients with rectal cancer treated with neoadjuvant chemoradiation therapy (CRT) followed by radical resection. Methods: Fifty-three consecutive patients were evaluated. The selection criteria included: adenocarcinoma of the mid- or distal rectum, locally advanced stage, absence of distant metastases, and preoperative CRT followed by proctectomy with total mesorectal excision. The operations included low anterior resection in 33 patients (62%) and abdominoperineal resection in 20 (38%). The outcome measures were: tumor regression, complete pathologic response, length of distal resection margins, status of radial margins and recurrence rate. Results: Forty-eight patients (91%) had tumor regression, and 11 (21%) had a complete pathologic response. Distal resection margins were tumor-free in all patients, ranging in length from 0.1 to 7.4 cm (mean = 2.2). Follow-up (mean = 48.8 months) was current in 50 of 53 patients (94%). There was no locoregional recurrence. Conclusions: Distal resection margins shorter than 1–2 cm appear to be equivalent to longer margins in patients who undergo CRT followed by proctectomy with total mesorectal excision. These findings may lead to greater utilization of sphincter-saving procedures in rectal cancer.

CP has similar morbidity and mortality rates to traditional pancreatic resections and may offer a lower incidence of diabetes and exocrine insufficiency.

The high-resolution HMD offered significantly better image quality and allowed faster task performance than a lower resolution model of HMD, and both performed better than the overhead display. The high-resolution HMD was not significantly more comfortable than the low-resolution model, given its added weight. HMDs alone may only be of incremental benefit in improving performance in laparoscopic surgery.However, their greatest promise is in their combination with other advances in imaging and image manipulation technology, as they open the door to individualized image display.

SNM is a safe and effective therapy for the treatment of FI. Postoperative patient surveillance is important, as many patients require programming changes, and some will require a lead revision over time.

The difficulty of performing a relatively simple laparoscopic task with paradoxic image display was almost insurmountable. Left-right image inversion was not sufficient to correct the handicap. Inverted mirror-image projection significantly improved performance, which almost reached control levels. The availability of personal image-display devices may, in the future, allow image customization for task performance in suboptimal conditions during endoscopic surgery.
