AI Article Synopsis
- The Pringle maneuver is a surgery technique that helps control bleeding but can hurt the liver.
- Researchers wanted to see if two medicines, N-acetylcysteine (NAC) and methylprednisolone (MET), could help protect the liver during surgery.
- In their study, patients who got either NAC or MET showed better liver recovery after surgery when the Pringle maneuver lasted more than 70 minutes compared to those who got a placebo (no treatment).
Article Abstract
Background: The Pringle maneuver, which is performed during liver surgery to reduce blood loss, may result in liver ischemia/reperfusion injury resulting in metabolic, immunological, and microvascular changes, which may lead to hepatocellular damage. The aim of this study was the investigation of the effects of N-acetylcysteine (NAC) and methylprednisolone (MET) in the modulation of liver warm ischemia during hepatic resection.
Methods: Forty-eight patients were enrolled in a pilot double-blind, randomized clinical trial. The patients received either NAC, MET, or placebo. The primary endpoint was the reduction in postoperative alanine aminotransferase and bilirubin. The secondary endpoint was the difference in morbidity and mortality.
Results: All the 48 patients had liver resection with no mortality. Morbidity was observed in 8 (16 %) patients equally distributed among the groups. There was a significant favorable recovery of liver function tests in patients treated with NAC or MET compared with the placebo when the Pringle maneuver exceeded 70 min.
Conclusions: The administration of NAC or MET prior to the Pringle maneuver during hepatic resection is associated with lower postoperative aberration in liver function tests compared with placebo when the Pringle maneuver exceeded 70 min. Larger studies are required to validate our findings and to investigate the specific role of NAC and MET in liver surgery.

Hepatic pregnancy, an exceedingly rare subtype of abdominal ectopic pregnancy, remains clinically challenging due to its infrequency, diverse presentations, and diagnostic difficulties. We report the clinical course, diagnostic journey and treatment of a woman with a primary hepatic pregnancy. The patient presented with acute pain in the right hypochondrium and vomiting.

Background: Internal bleeding is a common and serious complication in trauma patients. The American Association for the Surgery of Trauma (AAST) and the World Society of Emergency Surgery (WSES) have developed comprehensive guidelines to standardize and optimize the care of these patients. In Germany, abdominal injuries are involved in around 20% of all polytraumas, often caused by falls or road traffic accidents.

Article Synopsis
- Laparoscopic liver resection (LLR) is challenging and requires skilled scopists, with this study being the first to evaluate their impact on surgical outcomes during the procedure.
- The study included patients who underwent LLR over five years and categorized scopists into experts (10+ surgeries) and beginners (<10 surgeries) to analyze the effects of their skills on perioperative outcomes.
- Results showed no baseline differences, but beginner scopists caused significantly longer interruptions during surgery due to errors, suggesting that their lack of experience can increase stress for surgeons and extend operation times.

Article Synopsis
- The study aimed to assess the safety and effectiveness of using the Pringle maneuver with a bulldog clamp during laparoscopic liver resection.
- 80 patients were randomly assigned to either the intraperitoneal (IPM) or extraperitoneal (EPM) Pringle maneuver groups, measuring various preoperative, intraoperative, and postoperative liver function indices.
- Results showed that IPM had a shorter blocking and operation time, lower inflammatory response, less liver function injury, and quicker recovery compared to EPM, making it a safe and effective technique.

Appropriate surgical techniques for controlling bleeding and preserving residual liver function are key to the success of laparoscopic liver resection. This study aims to evaluate the application effect of intraoperative ultrasound in the Pringle maneuver of laparoscopic liver resection. Between January 2022 and June 2023, 100 patients underwent laparoscopic liver resection and were randomly allocated to receive application of intraoperative ultrasound for Pringle maneuver (intraoperative ultrasound group, = 50) or conventional Pringle maneuver (conventional group, = 50).
