Comparative Study With Propensity Score Matching Analysis of Two Different Methods of Transection During Hemi-Right Hepatectomy: Ultracision Harmonic Scalpel Versus Cavitron Ultrasonic Surgical Aspirator.

Background: Several devices are available for liver parenchyma transection (LPT). The aim of this study was to compare the Ultracision Harmonic scalpel (UHS) with the Cavitron Ultrasonic Surgical Aspirator (CUSA) among patients who underwent hemi-right hepatectomies (RH) to homogenize transection areas.

Methods: From September 2012 to June 2015, 24 patients who underwent the UHS surgery approach were matched with 24 patients who underwent the CUSA transection procedure for RH using propensity score matching.

Management of large incisional hernias with loss of domain: A prospective series of patients prepared by progressive preoperative pneumoperitoneum.

Background: The surgical treatment of giant incisional hernias with loss of domain is challenging due to the possibility of intra-abdominal hypertension after the herniated content is returned to the peritoneal cavity. Progressive preoperative pneumoperitoneum has been described before repair of the hernia, although its efficacy has not been demonstrated clearly. Our aim was to evaluate the efficacy of preoperative progressive pneumoperitoneum in expanding the volume of the peritoneal cavity and the outcomes after surgical treatment of incisional hernias with loss of domain.

Toward a Preoperative Classification of Lymph Node Metastases in Patients with Small Intestinal Neuroendocrine Tumors in the Era of Intestinal-Sparing Surgery.

Introduction: In patients with small intestinal neuroendocrine tumors (siNETs), surgical resection of the primary tumor and associated mesenteric lymph nodes (LNs) is recommended, but is not well standardized and can be risky in patients with superior mesenteric vessel involvement.

Objective: We aimed to evaluate the correlation between the length of resected small bowel and the number of removed LNs, and to propose a preoperative morphological classification of siNET-associated LNs.

Methods: The records of patients operated on for siNETs at two expert centers between August 2005 and November 2013 were analyzed.

Hepatic abscess: Diagnosis and management.

Microbial contamination of the liver parenchyma leading to hepatic abscess (HA) can occur via the bile ducts or vessels (arterial or portal) or directly, by contiguity. Infection is usually bacterial, sometimes parasitic, or very rarely fungal. In the Western world, bacterial (pyogenic) HA is most prevalent; the mortality is high approaching 15%, due mostly to patient debilitation and persistence of the underlying cause.
