Intra-operative assessment of axillary sentinel lymph nodes by frozen section-an observational study of 260 procedures.

Background: Sentinel lymph node biopsy (SLNB) has become the standard treatment for patients with invasive breast cancer. Intra-operative frozen section allows for the detection of nodal metastases, thereby allowing a simultaneous axillary lymph node dissection (ALND) for those patients with nodal metastases. We herein report the accuracy of frozen section in the detection of SLN metastases.

Laparoscopic intragastric approach for stromal tumours located at the posterior gastric wall.

Surgical resection is indicated for gastrointestinal stromal tumour (GIST). Laparoscopic resection with clear margins is effective in gastric GIST. However, GIST located in the posterior gastric wall with close proximity to the oesophagogastric junction poses special challenges.

Randomized trial comparing pantoprazole infusion, bolus and no treatment on gastric pH and recurrent bleeding in peptic ulcers.

Background: To study the effects of pantoprazole on gastric pH and recurrent bleeding after endoscopic treatment for bleeding peptic ulcers.

Methods: After endoscopic haemostasis, patients were randomly assigned to infusion group (pantoprazole 80 mg i.v.
