Purpose: The feasibility and potential advantages of laparoscopic diagnosis and repair of incarcerated obturator hernia (OH) is debated. The aim of this retrospective study was to compare short-term complications comparing laparoscopic to open repair of OH.
Methods: A total of 29 preoperatively diagnosed patients underwent surgery for a preoperatively diagnosed OH between January 2006 and July 2017. The patients were divided into a laparoscopic group (11 patients underwent laparoscopic repair; 8 without and 3 with intestinal resection) and an open group (18 patients who underwent open repair; 9 without and 9 with intestinal resection).The outcomes were compared between groups. A risk factor analysis for postoperative complications was performed.
Results: The incidence of postoperative complications was fewer in the laparoscopic group [9.0% vs. 61.1%; (p < 0.001)]. The bleeding amount [1.2 g vs. 40.4 g; (p = 0.087)] and postoperative length of stay [13.3 days vs. 17.1 days; (p = 0.072)] showed a tendency to be favorable in the laparoscopic group. Occult contralateral OH was detected in three patients (27.7%) in the laparoscopic group and one patient (5.5%) in the open group (p = 0.099). Open surgery and intestinal resection were independent risk factors for a postoperative complication. One patient in the open group developed an incarcerated OH on the contralateral side 1 year after the first surgery.
Conclusions: Laparoscopic repair for incarcerated obturator hernia demonstrated more favorable short-term outcomes compared with open repair in terms of a lower incidence of postoperative complications and it was potentially beneficial for detecting and repairing an occult OH on the contralateral side.

Is Intracranial Pressure Monitoring After Open Cranial Procedures Associated With Outcome?
J Surg Res
January 2025
Division of Trauma and Critical Care, Department of Surgery, Reading Hospital, West Reading, Pennsylvania. Electronic address:
Introduction: It is unclear if intracranial pressure monitoring (ICPM) after open cranial procedures (craniotomy or craniectomy) (OC) for traumatic brain injury is associated with mortality. We hypothesized that ICPM placed early after OC was associated with lower mortality compared to no ICPM or delayed ICPM placement.
Methods: Using 2020-2021 data from the American College of Surgeons Trauma Quality Improvement Program, patients ≥16 y from level 1 and 2 trauma centers who underwent OC were divided into two groups: ICPM placed within 72 h of OC (early) and no ICPM or ICPM placed after 72 h (none/delayed).
Reducing Surgical Site Infections With Silver Impregnated Dressings in Lower Extremity Bypass Patients.
J Surg Res
January 2025
Department of Surgery, Albany Medical Center, Albany, New York; Division of Vascular Surgery, Albany Medical Center, Albany, New York.
Introduction: Surgical site infection (SSI) after lower extremity (LE) bypass surgery is associated with longer length of stay, higher hospital cost, increased morbidity, and even graft loss. Silver impregnated dressings have been used by other surgical subspecialties to decrease SSI with reported success. The National Surgical Quality Improvement Program (NSQIP) published a national expected rate of 7.

Department of Obstetrics and Gynecology, University of Ulsan College of Medicine, Asan Medical Center, Seoul, Republic of Korea.
Objective: The aim of the study was to evaluate the hemostatic efficacy of the fibrin sealant patch (TachoSil) after loop electrosurgical excision (LEEP) and its influence on other complications and quality of life (QoL).
Materials And Methods: This single-blind, prospective, randomized study involved patients undergoing LEEP with or without TachoSil (1:1) between August 2014 and August 2015 in Asan Medical Center, Korea. Primary outcome measures were bleeding duration and the frequency of additional treatment owing to vaginal bleeding within 2 weeks after LEEP.

Background: Abelacimab is a fully human monoclonal antibody that binds to the inactive form of factor XI and blocks its activation. The safety of abelacimab as compared with a direct oral anticoagulant in patients with atrial fibrillation is unknown.
Methods: Patients with atrial fibrillation and a moderate-to-high risk of stroke were randomly assigned, in a 1:1:1 ratio, to receive subcutaneous injection of abelacimab (150 mg or 90 mg once monthly) administered in a blinded fashion or oral rivaroxaban (20 mg once daily) administered in an open-label fashion.
Does Resilience Change in Patients Undergoing Shoulder Surgery? A Retrospective Comparative Study Utilizing the Brief Resilience Scale.
Clin Orthop Relat Res
January 2025
Department of Orthopaedic Surgery, Mayo Clinic, Phoenix, AZ, USA.
Background: Resilience refers to the ability to adapt or recover from stress. There is increasing appreciation that it plays an important role in wholistic patient-centered care and may affect patient outcomes, including those of orthopaedic surgery. Despite being a focus of the current orthopaedic evidence, there is no strong understanding yet of whether resilience is a stable patient quality or a dynamic one that may be modified perioperatively to improve patient-reported outcome scores.
