Acute cholecystitis treated with urgent cholecystectomy achieves higher rate of critical view of safety when compared to interval cholecystectomy after tube cholecystostomy.

Background: There are few reported outcomes of treatment of acute cholecystitis incorporating current guidelines for gallbladder dissection techniques and use of percutaneous tube cholecystostomy (PCT). The authors hypothesize PCT allows regression of peritoneal inflammation, but infundibular inflammation is increased at interval cholecystectomy, resulting in greater requirement for advanced dissection techniques.

Methods: Between December 2009 and July 2023, 1222 patients were admitted with acute cholecystitis and ultimately underwent cholecystectomy.

Combined division of the splenic vessels and pancreatic parenchyma during laparoscopic distal pancreatectomy is a safe alternative to separate division: a single-institution retrospective study.

Background: Limited data exists regarding the safety and outcomes of combined division of the splenic vessels with the pancreatic parenchyma during laparoscopic distal pancreatectomy (LDP). This study aims to evaluate the combined division technique.

Methods: Patients who underwent LDP for pancreatic cancer from April 2011 to December 2022 were retrospectively reviewed and categorized into the following groups: combined (CV) versus separate (SV) division of the splenic vein; combined (CA) versus separate (SA) division of the splenic artery; and combined (CAV) versus separate (SAV) division of the splenic artery and vein, with or without the pancreatic parenchyma.

Morphological Analysis of a New Species of (Teleostei: Centrarchidae) from Lake Erie, PA, USA.

This previously undescribed species of is described from collections in Lake Erie. The species was first recognized by the tri-colored tail of juveniles. This tri-colored tail, the presence of bold parallel lines ventral to the lateral band, and scales in the inter-radial membranes of the dorsal fin distinguish it from .
