Quest for the optimal technique of laparoscopic splenectomy - vessels first or hilar transection?

The aim of this study was to compare clinical and pathological results from these two techniques in patients undergoing rectal resections because of low rectal cancer.

Materials And Methods: Thirty-five patients undergoing TaTME were matched with 35 patients operated on using LaTME.

Defunctioning ileostomy reduces leakage rate in rectal cancer surgery - systematic review and meta-analysis.

Objectives: The role of a defunctioning ileostomy in every anterior rectal resection with total mesorectal excision (TME) is still controversial.

Methods: MEDLINE, Embase and Cochrane Library were searched for eligible studies.

More stapler firings increase the risk of perioperative morbidity after laparoscopic sleeve gastrectomy.

Introduction: Staple-line bleeding and leakage are the most common serious complications of laparoscopic sleeve gastrectomy. The relationship between multiple stapler firings and higher risk of postoperative complications is well defined in colorectal surgery but has not been addressed in bariatric procedures so far. Identification of new factors such as "the numbers of stapler firings used during laparoscopic sleeve gastrectomy (LSG)" as a predictor for complications can lead to optimization of the patient care at bariatric centers.

Material And Methods: The study enrolled 275 patients who underwent LTA.

Are we ready for the ERAS protocol in colorectal surgery?

Introduction: Modern perioperative care principles in elective colorectal surgery have already been established by international surgical authorities. Nevertheless, barriers to the introduction of routine evidence-based clinical care and changing dogmas still exist. One of the factors is the surgeon.

Therapeutic Effect of Low Doses of Acenocoumarol in the Course of Ischemia/Reperfusion-Induced Acute Pancreatitis in Rats.

Unlabelled: Intravascular activation of coagulation is observed in acute pancreatitis and is related to the severity of this inflammation. The aim of our study was to evaluate the impact of acenocoumarol therapy on the course of acute pancreatitis induced in male rats by pancreatic ischemia followed by reperfusion. Acenocoumarol at a dose of 50, 100, or 150 µg/kg/dose was administered intragastrically once a day, starting the first dose 24 h after the initiation of pancreatic reperfusion.

A Periampullary Duodenal Diverticula in Patient with Choledocholithiasis - Single Endoscopic Center Experience.

Unlabelled: The reported prevalence of periampullary duodenal diverticula varies between 9 and 32.8%. The aim of the study was to evaluate the prevalence of periampullary diverticula in the studied population and establish whether their presence influence the risk of choledocholithiasis and the risk of Endoscopic Retrograde Cholangio Pancreatography (ERCP) related complications.

Regardless the technique the most significant problem of pancreatic surgery is postoperative pancreatic fistula.

Severe Developmental B Lymphopoietic Defects in Foxp3-Deficient Mice are Refractory to Adoptive Regulatory T Cell Therapy.

The role of Foxp3-expressing regulatory T (T(reg)) cells in tolerance and autoimmunity is well-established. However, although of considerable clinical interest, the role of T(reg) cells in the regulation of hematopoietic homeostasis remains poorly understood. Thus, we analysed B and T lymphopoiesis in the scurfy (Sf) mouse model of T(reg) cell deficiency.

Aim of the present study was to discover what is the reason for these opposite confusing results and to determine the role of sensory nerves in this effect. Acute pancreatitis was induced in rats by cerulein.
