Laparoscopy management for spontaneous bladder rupture: a case report.

We present a case of a 79-year-old man with lower abdominal pain and negative Blumberg sign. An indwelling bladder catheter was inserted for urinary retention due to a tight phimosis 2 months earlier. A contrast-enhanced computed tomography scan revealed a huge gastrectasia and small bowel distention due to a suspected adherent bridle. The clinical signs and the laboratory tests were highly suspicious for bowel obstruction and emergency surgery was indicated. Exploratory laparoscopy showed a bladder hole tamponade by an ileum loop. The perforation was sutured laparoscopically and the patient was discharged on the 14th postoperative day. In our case, emergency laparoscopic exploration was useful for the diagnosis and the treatment of spontaneous bladder rupture. We hope this case report can be useful to give these patients better outcomes. Notably we would like to emphasize that the presence of a urinary catheter can be a risk factor for intraperitoneal bladder rupture.

Gastric cancer: extent of lymph node dissection and requirements for a correct staging.

AIMS AND BACKGROUND: Lymphatic spread is an important prognostic factor in gastric cancer. The TNM classification requires at least 15 lymph nodes to stage and identify three prognostic groups according to the number of metastatic lymph nodes: N1 (1-6), N2 (7-15), N3 (> 15). The aim of this study was to investigate which type of lymph node dissection allows an accurate staging. METHODS: From 1996 to 2001, we treated 140 gastric cancer patients, 27 with D1 and 113 with D2 dissection. We evaluated lymph node count, status and ratio between metastatic and total number of excised lymph nodes, keeping 20% as the cutoff value. RESULTS: The mean number of lymph nodes was 18 and 33 respectively for D1 and D2 (P < 0.001), 41% of patients in D1 and 5% in D2 had less than 15 lymph nodes (P < 0.001). 59% in D1 and 73% in D2 (P = 0.145) had lymph node metastases, but this incidence decreased to 36% (P = 0.045) and 16% (P < 0.001) respectively for D1 and D2 when less than 15 lymph nodes were available. Considering the ratio between metastatic and total number of lymph nodes, 45% of D1 versus 3% of D2 (P < 0.001) in the N1 group exceeded 20%. CONCLUSIONS: D2 lymph node dissection is better than D1 in providing at least 15 lymph nodes required for a correct staging. We confirm the risk of a downstage when less than 15 lymph nodes are available.
