Pancreatic insulinoma: a surgical experience.

Background: Small size, high benignity rate, and sporadic nature make insulinomas suitable for laparoscopic resection. On the other hand, occult location or multicentricity mandate open surgery. This study was designed to analyze a series of patients who had pancreatic insulinomas and underwent initial treatment at our institution.

Maximal weight loss after banded and unbanded laparoscopic Roux-en-Y gastric bypass: a randomized controlled trial.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) leads to significant weight loss and correction of co-morbidities in most patients. Banded LRYGB was designed to enhance weight loss and avoid weight regain.

Methods: A randomized controlled pilot trial was designed to comparatively analyze the results and complications of banded (6.

[Laparoscopic surgery of pancreas].

Unlabelled: In pancreatic diseases, laparoscopic surgery is used to drain fluid collections in infected pancreatic necrosis, abscesses and pseudocysts, for cancer staging, to resect both benign and malignant tumors and for palliative procedures as well. In patients with intractable pain, percutaneous or surgical celiac plexus block can be performed, celiac ganglion alcoholization and torachoscopic splacnicectomy can be done. The laparoscopic approach for staging, allows us to identify very small peritoneal or hepatic metastasis, local invasion or deep hepatic metastasis.
