SINGLE-ACCESS TRANSUMBILICAL LAPAROSCOPIC APPENDECTOMY USING CURVED REUSABLE INSTRUMENTS: AN INITIAL REPORT OF THREE CASES.

Introduction: The continuous evolution of laparoscopic surgery and the ambition of better cosmetic results raise the need for less invasive procedures. The umbilicus represents a natural scar and constitutes a well-healing site of access to the peritoneal cavity. Single-access Transumbilical Laparoscopy (SATL) is gaining popularity and can be an alternative surgical treatment for acute appendicitis.

PRIMARY RETROPERITONEAL EXTRA-ORGAN TUMORS (PRET) - SURGICAL TACTICS.

Introduction: Retroperitoneal tumors, in general, are rare tumors which histopathological characteristics and biological behavior can be considered as benign or malignant. They originate from various tissue elements located in the retroperitoneal space. They often cover Anatomical structures of varying importance - mainly retroperitoneal vessels and organs, which determines the type of surgery - radical or palliative.

Constraints on models of the Higgs boson with exotic spin and parity using decays to bottom-antibottom quarks in the full CDF data set.

A search for particles with the same mass and couplings as those of the standard model Higgs boson but different spin and parity quantum numbers is presented. We test two specific alternative Higgs boson hypotheses: a pseudoscalar Higgs boson with spin-parity J^{P}=0^{-} and a gravitonlike Higgs boson with J^{P}=2^{+}, assuming for both a mass of 125  GeV/c^{2}. We search for these exotic states produced in association with a vector boson and decaying into a bottom-antibottom quark pair.

Postoperative complications after Nissen fundoplication.

Anti-reflux laparoscopic operations replaced conventional surgery and are now widely available, because of the advantages of this type of surgery. One of the main reasons for the high complications rate in this type of operations is the lack of experience of the surgeons, although recently in the reports of most leading authors complications and increased mortality rate is due to the older patients undergoing this type of surgery. The main causes of death were gastrointestinal hemorrhage, necrosis with perforation of the esophagus or stomach, cardiac arrest, respiratory and inflammatory complications, and pulmonary thromboembolism.
