Laparoscopic pancreatic surgery (LapPS) for management of benign pancreatic tumors has still not been defined. This paper evaluates the feasibility and outcome of LapPS in patients with endocrine pancreatic tumors (EPTs) and cystic neoplasms of the pancreas (CyNP). Eighteen patients with benign pancreatic tumors underwent LapPS between January 1998 and May 2001. The indications were 10 EPTs (6 sporadic insulinomas, 1 multiple insulinoma of multiple endocrine neoplasia type 1, 2 nonfunctioning tumors, 1 VIPoma) and 8 CyNPs (3 serous cystadenomas, 5 mucinous cystic neoplasms). The laparoscopic procedure was performed using four ports with patients in the half-lateral position. Laparoscopic ultrasonography (LapUS) was used in all cases. Laparoscopic enucleation (LapE) was planned in five patients and performed in four (one conversion for tumor not found during laparoscopy). Laparoscopic pancreatic resection (LapPR) with spleen salvage was planned in 13 patients and performed in 12 (one conversion for metastatic VIPoma), with splenic vessel preservation in 11 patients and short gastric vessel preservation in 1. The average operating time was 3.5 hours after enucleation, 4.0 hours after distal pancreatectomy, and 5.0 hours after subtotal pancreatectomy. Pancreatic fistula was observed in two patients after LapE and in three patients after LapPR. Splenectomy for splenic abscess was performed 1 week after surgery in a patient with short gastric vessel splenic preservation. The average hospital stay was 5 days. We concluded that LapPS is a safe method for removing EPTs and CyNPs, although the incidence of pancreatic fistulas remains high. In selected patients LapPS offers significant benefit to patients: reduced trauma to the abdominal wall, short hospital stay, and a quick postoperative recovery.

Pain is a highly prevalent symptom in patients with cancer. Despite therapeutic advances and well-accepted treatment guidelines, a percentage of patients with pain are under-treated. Currently, it has been recognized that several barriers in pain management still exist and, in addition, there are new challenges surrounding complex subtypes of pain, such as breakthrough and neuropathic pain, requiring further reviews and recommendations. This is an update of the guide our society previously published and represents the continued commitment of SEOM to move forward and improve supportive care of cancer patients.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are the principal risk factor associated to end-stage liver diseases in the world. A study was carried out on end-stage liver disease cases admitted to an important hepatology unit in Medellin, the second largest city in Colombia. From 131 patients recruited in this prospective study, 71% of cases were diagnosed as cirrhosis, 12.2% as HCC, and 16.8% as cirrhosis and HCC. Regarding the risk factors of these patients, alcohol consumption was the most frequent (37.4%), followed by viral etiology (17.6%). Blood and/or hepatic tissue samples from patients with serological markers for HCV or HBV infection were characterized; on the basis of the phylogenetic analysis of HCV 5′ UTR and HBV S gene, isolates belonged to HCV/1 and HBV/F3, respectively. These results confirm the presence of strains associated with poor clinical outcome, in patients with liver disease in Colombia; additionally, HBV basal core promoter double mutant was identified in HCC cases. Here we show the first study of cirrhosis and/or HCC in Colombian and HBV and HCV molecular characterization of these patients. Viral aetiology was not the main risk factor in this cohort but alcohol consumption.
