Laparoscopy is a safe and effective procedure for the treatment of acute SBO in selected patients. This approach requires surgeons to have a low threshold for conversion to laparotomy. Laparoscopic treatment appears to result in an earlier return of bowel function and a shorter postoperative length of stay, and it will likely have lower costs.

Laparoscopic Roux-en-Y gastric bypass (LGB) is one of the most popular surgeries for morbid obesity. Robotic use is also on the rise. Data concerning outcomes is limited, hence the need for more information. The first 100 robotic-assisted bypasses by one surgeon in one institution were studied. Data obtained from clinic notes and hospital records included all who underwent the procedure. There were 79 females and 21 males. Mean age and body mass index were 42 years and 48 kg/m2, respectively. Comorbidities included diabetes, 22 per cent; hypertension, 47 per cent, gastroesophageal reflux disease, 40 per cent; obstructive sleep apnea, 53 per cent; dyslipidemia, 17 per cent; and heart disease, 8 per cent. Prior surgeries included cesarean -section, 26 per cent; cholecystectomy, 17 per cent; hysterectomy, 3 per cent; hernia, 1 per cent, and other abdominal surgery, 27 per cent. Intraoperatively procedures included adhesiolysis, 22 per cent; cholecystectomy, 16 per cent; and herniorrhaphy, 3 per cent. Average time was 177.7 minutes. Mean stay was 1.51 days. Thirty-day mortality was 0. Emergency department re-evaluations included 13. Most were minor problems. There was one gastrojejunal leak. Early complications included leak, thrombosis, and bleeding requiring transfusion in four patients. There were four strictures. Overall follow up was greater than 90 per cent. Average weight loss was 21.2 per cent of excess body weight by Month 1, 33.8 per cent by Month 3, and 50.7 per cent by Month 6. Learning curves for time and major complications were 30 and 50 cases, respectively (P = 0.03, 0.04). Robotic use in bariatrics is possible in community hospitals. Although technologies are still in their infancy, complication rates and weight loss are comparable to nonrobotic procedures.

Ultrasound (US) has been reported as a useful aid to increase the sensitivity and specificity of the diagnosis of appendicitis. To determine the accuracy of US, we performed a prospective study of patients evaluated in the emergency department for acute appendicitis. US results of 125 consecutive patients over an 11-month period were correlated with operative and pathologic findings and clinical follow-up. The appendix was visualized as a noncompressible structure in 19 patients, and 18 had appendicitis (95%). Ten of the 12 patients with abnormal Doppler activity in the appendix had appendicitis (83%). Conversely, the appendix could not be visualized in 102 patients, and 100 did not have appendicitis (98%). One hundred five of the 113 patients (93%) with absent abnormal Doppler activity did not have appendicitis. Ninety-four of the 125 patients had neither visualization of the appendix nor abnormal activity, and 2 had appendicitis. The sensitivity of US for appendicitis was 90 per cent, and the specificity was 94 per cent. Visualization of the noncompressible appendix or abnormal Doppler activity strongly suggests appendicitis. More importantly, the absence of both of these ultrasonographic findings defines a patient subset that may be safely discharged from the emergency department without admission.
