Spontaneous bladder rupture mimicking a jejuno-ileal perforation.

Spontaneous urinary bladder perforation is a very rare disease. The main cause of urinary perforation, indeed, is a damage to the urinary bladder wall by blunt or penetrating trauma. There are only few idiopathic spontaneous rupture of urinary bladder (ISRUB) cases reported in the literature. Pre-operative diagnosis is very difficult due to similar symptoms, laboratory and imaging findings of a gastrointestinal perforation that is usually excluded intraoperatively. Herein we report a case of a 91-year-old man presented to the emergency department with a spontaneous bladder perforation mimicking an ileal perforation.

Evaluation of the robotic approach concerning pitfalls in rectal surgery.

INTRODUCTION: The feasibility and advantages of robotic rectal surgery (RRS) in comparison to conventional open or laparoscopic rectal resections have been postulated in several reports. But well-known challenges and pitfalls of minimal invasive rectal surgery have not been evaluated by a prospective, multicenter setting so far. Aim of this study was to analyze the perioperative outcome of patients following RRS especially in regard to the pitfalls such as obesity, male patients and low tumors by a European multicenter setting. METHODS: This prospective study included 348 patients undergoing robotic surgery due to rectal cancer in six major European centers. Clinicopathological parameters, morbidity, perioperative recovery and short-term outcome were analyzed. RESULTS: A total of 283 restorative surgeries and 65 abdominoperineal resections were carried out. The conversion rate was 4.3%, mean blood loss was 191 ml, and mean operative time was 315 min. Postoperative complications with a Clavien-Dindo score >2 were observed in 13.5%. Obesity and low rectal tumors showed no significant higher rates of major complications or impaired oncological parameters. Male patients had significant higher rates of major complications and anastomotic leakage (p = 0.048 and p = 0.007, respectively). DISCUSSION: RRS is a promising tool for improvement of rectal resections. The well-known pitfalls of minimal-invasive rectal surgery like obesity and low tumors were sufficiently managed by RRS. However, RRS showed significantly higher rates of major complications and anastomotic leakage in male patients, which has to be evaluated by future randomized trials.

Integrated clinical-ultrasonographic diagnosis in acute appendicitis.

PURPOSE: Acute appendicitis is one of the commonest diseases encountered in the field of emergency surgery. If untreated, it can rapidly develop severe complications such as perforation and peritonitis. Surgeons therefore often choose early surgical treatment also when the diagnosis is only probable, facing the risk of performing an elevated amount of unnecessary appendectomies. The aim of this study is to analyse our experience with integrated clinical-ultrasonographic diagnosis in acute appendicitis. MATERIAL AND METHODS: From January 1999 to December 2006, 1447 patients underwent clinical examination, leucocyte count, evaluation of C-reactive protein level, and abdominal ultrasonography using graded compression technique and a high frequency probe. RESULTS: In 368 patients (25%) ultrasonographic diagnosis was acute appendicitis; 8 patients were operated on the basis of clinical evaluation only. Ultrasonography yielded false positive results in 7 cases. In 1079 patients (75%) diagnosis was negative for acute appendicitis; 173 of these patients (12%) received a different diagnosis. The remaining 906 patients underwent clinical follow-up until the symptoms disappeared; there were no complications. In our study, sensitivity of ultrasonography was 98%, specificity 99%, positive predictive value 98%, and negative predictive value 99%. Overall diagnostic accuracy was 99%. CONCLUSION: Integrated diagnosis of acute appendicitis based on clinical evaluation, laboratory tests and ultrasonography is safe and saves resources by preventing unnecessary operations.
