Percutaneous cholecystostomy: a bridge to surgery or definite management of acute cholecystitis in high-risk patients?

OBJECTIVE: Cholecystectomy is the standard treatment for acute cholecystitis, but in high-risk patients with serious comorbidity and in patients of advanced age there is substantial morbidity and mortality associated with the intervention. In these selected patients, percutaneous cholecystostomy (PCS) is an alternative mode of management. The aim of the present study was to evaluate the outcome of PCS in selected patients with acute cholecystitis. MATERIAL AND METHODS: Thirty-five patients, representing 0.6% of all acute cholecystitis patients managed during the period 1994-2003, were subjected to PCS. Patients' charts were reviewed retrospectively for age, gender, comorbidity, hospital stay, procedure, complications and final outcome, including requirement of additional interventions. RESULTS: PCS was considered successful in 34/35 patients, 26 of whom responded within 3 days. Two patients required additional cholecystectomy 3 days and 20 months, respectively, after the PCS procedure. Two patients underwent endoscopic retrograde cholangiopancreatography (ERCP) and one patient underwent rotation lithotripsy. Four patients suffered recurrent biliary complaints after the acute episode of cholecystitis, while the only serious procedure-related complication was bile leakage from the gallbladder in one patient, which necessitated cholecystectomy. CONCLUSIONS: PCS is a comparatively safe and efficient procedure in the treatment of acute cholecystitis in high-risk patients with serious comorbidity and in elderly patients, contraindicating the general anaesthesia required for laparoscopic or open cholecystectomy.

Severity of pancreatitis-associated gut barrier dysfunction is reduced following treatment with the PAF inhibitor lexipafant.

The aim of the present study was to investigate the potential effect of treatment with a platelet-activating factor (PAF) antagonist, lexipafant (BB-882), on gut endothelial and epithelial barrier dysfunction and leukocyte recruitment in rats with acute pancreatitis. Severe acute pancreatitis was induced by the intraductal administration of 5% sodium taurodeoxycholate and pancreatitis-associated gut barrier dysfunction was characterized by increased exudation of radiolabelled albumin into the interstitium and alterations in bidirectional (over both the endothelial and epithelial barrier components) permeability of the intestine at the early stage of bile salt-induced acute pancreatitis. Levels of interleukin 1beta and 6, ileal and colonic myeloperoxidase (MPO) content, clearance of radiolabelled albumin from blood to the gut lumen or gut lumen to blood, and leakage of radiolabelled albumin to the ileum or colon were measured 3 and 12h after induction of acute pancreatitis. Treatment with lexipafant 30 min and 6h after pancreatitis reduced severity of pancreatitis-associated intestinal dysfunction, associated with a diminish in systemic concentrations of IL-1 and local leukocyte recruitment. The findings imply that PAF plays a critical role in the development of pancreatitis-associated gut barrier dysfunction and that PAF antagonist in some forms may represent potential candidates for future therapeutic intervention.

Laparoscopic extraperitoneal inguinal hernia repair versus open mesh repair: a prospective randomized controlled trial.

BACKGROUND: This study was designed to compare an open tension-free technique (Lichtenstein repair) with a laparoscopic totally extraperitoneal hernia repair (TEP). METHODS: One hundred sixty-eight men aged 30 to 65 years with primary or recurrent inguinal hernia were randomized to TEP or open mesh technique in the manner of Lichtenstein. Follow-up was after 1 and 6 weeks, and 1 year. RESULTS: Eighty-one patients were randomized to TEP, and 87 to open repair. For 1 patient in each group, the operation was converted to a different type of repair. No difference was seen in overall complications between the 2 groups. However, 1 patient in the TEP group underwent operation for small bowel obstruction after surgery. A higher frequency of postoperative hematomas was seen in the open group (P <.05). Patients in the TEP group consumed less analgesic after surgery (P <.001), returned to work earlier (P <.01), and had a shorter time to full recovery (P <.01). Two recurrences occurred in the TEP group 1 year after surgery. CONCLUSION: The TEP technique was associated with less postoperative pain, a shorter time to full recovery, and an earlier return to work compared with the open tension-free repair. No difference was seen in overall complications. However, 2 recurrences did occur after 1 year in the TEP group.
