Table of Contents
The online formats of SRGS include access to What You Should Know (WYSK): commentaries on articles published recently in top medical journals. These commentaries, written by practicing surgeons and other medical experts, focus on the strengths and weaknesses of the research, as well as on the articles' contributions in advancing the field of surgery.
Below is a sample of one of the commentaries published in the current edition of WYSK.

Commentary by: Gerald A. Isenberg, MD, FACS, FASCRS
A recent article presented at an ASA meeting explored the use of MRI in guiding surgical decisions for rectal cancer patients with lateral pelvic lymph node (LPLN) involvement. Subsequent discussion clarifies several important points.
Management of LPLN in rectal cancer presents two primary strategies:
Preoperative MRI may assist in tailoring the treatment approach to individual patients. While LPLND is standard in Japan, it is less common in Western settings. In this retrospective review, Peacock employs MRI criteria—short-axis size, malignant signal characteristics, and margin features—to aid in identifying LPLN positivity. The study compared outcomes between two groups with preoperative scans indicating possible LPLN involvement: those who underwent LPLND and those who did not.
Median follow-up was 20 months (considered short by this author). LPLND resulted in longer operative time, but blood loss and major complications were similar between groups. Lateral recurrence rates were nearly identical. As expected, patients meeting the MRI criteria were more likely to receive LPLND. The authors conclude that MRI can aid in the appropriate selection of patients for LPLND.
Unfortunately, the study does not provide a definitive answer regarding the necessity of LPLND. It does highlight the potential of MRI with a rectal cancer protocol as a decision-making aid for surgeons. Further studies should explore the specific indications for LPLND and identify training needs for surgeons who are less familiar with the procedure. Importantly, standard TME addresses most lymph node metastases due to its mesorectal focus.

Radmayr and colleagues advocate for clinical observation of retractile testes and recommend orchidopexy for undescended testes before 12 months of age. For non-palpable testes, they state that evaluation for disorders of sex development is indicated; if this is unrevealing, laparoscopic exploration should be pursued. The guidelines advise against hormonal therapy and include diagnostic and therapeutic algorithms.

Antala and Taylor provide a comprehensive update on biliary atresia, detailing its potential multifactorial etiology, including genetic predispositions, in utero injuries, viral infections, and aberrant immune responses. The authors emphasize the necessity of immediate Kasai portoenterostomy upon diagnostic confirmation, while acknowledging that progressive hepatic injury frequently occurs post-procedure despite establishment of biliary drainage.

Russell and coauthors, in their consensus statement, address key aspects of managing pediatric traumatic hemorrhagic shock, including: hemostatic resuscitation strategies utilizing blood products, prehospital care considerations (airway management, blood pressure targets, tourniquet application), the role of hemostatic adjuncts, and coagulation monitoring during resuscitation. The recommendations strongly support blood product-based resuscitation over crystalloid infusions, citing evidence of reduced mortality and decreased ventilator requirements. A 1:1 plasma-to-red blood cell (RBC) ratio and a high platelet-to-RBC ratio are advocated for resuscitating injured children.
