Purpose: To describe preoperative anatomical features of Stage 5 retinopathy of prematurity with results of surgery and patient-related and surgery-related factors affecting postoperative success.
Methods: Forty eyes of 33 infants who underwent vitrectomy with lensectomy or lens-sparing vitrectomy for Stage 5 retinopathy of prematurity were enrolled. Stage 5 cases were divided into different groups according to their preoperative anatomical features as follows: A: for eyes with ophthalmoscopically observable total retinal detachment; B: for eyes with total leucocoria associated with funnel retinal detachment; and C: for eyes with very shallow anterior chamber and corneal opacity. Only A and B eyes underwent surgery. The effect of the presence of vascular dilation and tortuosity, preoperative treatment status, surgically induced posterior hyaloid detachment, and sparing the lens on anatomical and functional results was evaluated.
Results: Thirty-five percentage of the eyes were in Group A and 65% were in Group B. The mean follow-up was 30.6 months (12-68). Anatomical success was 55.5% for Group A and 15.4% for Group B (P: 0.047), and functional success was 33.3% for Group A and 7.7% for Group B at the third year (P: 0.125). The presence of vascular dilation and tortuosity and postoperative vitreous hemorrhage were found to have negative effects; preoperative treatment and surgical induction of posterior hyaloid detachment were found to have positive effects on anatomical and functional results.
Conclusion: Surgery for ophthalmoscopically observable retinopathy of prematurity-associated retinal detachment resulted in better anatomical and functional outcomes, and the results are even better in eyes with preoperative treatment, lens-sparing vitrectomy, and surgically induced posterior hyaloid detachment.

Introduction And Importance: Debulking surgery is the main approach for recurrent adult granulosa cell tumors (AGCTs), but the effectiveness of laparoscopic extensive cytoreduction in advanced cases and its impact on quality of life (QoL) remains unclear.
Case Presentation: A 34-year-old woman, who had a right adnexectomy for AGCT in 2020, was referred with an 8-month history of a large left ovarian cyst and amenorrhea. Preoperative evaluations indicated a recurrence 18 months post-diagnosis.

Introduction: Giant inguinoscrotal hernias (GIH), defined as hernias extending below the inner thigh midpoint in a standing position, are rare and often seen in resource-limited settings due to delayed medical care. These hernias pose surgical challenges, particularly in low- and middle-income countries (LMICs), where standardized management protocols are lacking, and risks such as cardiorespiratory compromise are significant.
Case Presentation: A 55-year-old male presented with a large, irreducible right inguinoscrotal hernia of 1.
Impact of Caudate Lobe Resection on Overall Survival and Liver Disease-Free Survival in Colorectal Liver Metastases: A Pilot Study.

Department of Radiology, Afyonkarahisar Health Sciences University, Türkiye.
Background/Aims: The objective of this study was to evaluate the impact of the resected caudate lobe on survival, particularly in the context of anatomical resection of liver metastases in colorectal cancers without metastases in the caudate lobe. Materials and Methods: Patient data were extracted from the dataset titled "Preoperative CT and Survival Data for Patients Undergoing Resection of Colorectal Liver Metastases (CRLM)." The analysis specifically concentrated on individuals who underwent complete cau- date lobe resection in the absence of radiological signs of metastasis within the caudate lobe itself.

Anastomotic leakage (AL) is a significant complication following rectal cancer surgery, adversely affecting both quality of life and oncological outcomes. Recent advancements in artificial intelligence (AI), particularly machine learning and deep learning, offer promising avenues for predicting and preventing AL. These technologies can analyze extensive clinical datasets to identify preoperative and perioperative risk factors such as malnutrition, body composition, and radiological features.

The cystic artery is a critical anatomical landmark in both laparoscopic and open cholecystectomy. This report presents a unique case involving two rare anatomical variations: double cystic arteries, along with a superficial branch originating from the superior mesenteric artery (SMA) - a previously unreported combination with significant clinical and surgical implications. Unlike earlier studies, this research provides detailed anatomical and embryological insights supported by high-quality imaging and illustrations to guide surgeons in recognizing and managing this novel variation.
