ABSTRACT
Background and Aims: Perianal fistula is a prevalent anorectal condition originating from an infectious crypt extending to the external opening. Multiple surgical methods exist for treating perianal fistulas; however, selecting the appropriate options is still controversial. Our study aims to evaluate seton replacement versus other surgical methods in treating perianal fistula. Methods: This study recruited 72 patients presenting with perianal discharge and diagnosed with perianal fistula through intra-sphincteric, trans-sphincteric, and supra-sphincteric examinations at Imam Reza and Besat Hospitals from July 2022 up to March 2023. Regarding case-control design, patients were divided into two groups: the first group (n = 36) underwent seton insertion, while the control group (n = 36) received alternative surgical methods. Follow-up was conducted for 1 month post-discharge, with monthly visits for 6 months. Patients were evaluated for fistula tract healing, seton loosening, and daily secretion rate (based on infected pads) during each visit. Finally, the two groups were compared in terms of improvement rates. Results: In the seton group, approximately 94.4% of patients showed improvement. However, the difference between the groups was insignificant (p = 0.494). Seton replacement was performed in 52% of patients, with the majority requiring replacement twice (61%). Improvement rates were highest among cases with two seton replacements, although the difference was not statistically significant (p = 0.073). Following seton replacement, the most common treatment methods were endoanal flap and fistulotomy, with observed improvement in 10 cases for each procedure. Conclusion: This study highlights that draining seton remains a primary choice for intermediate treatment due to its satisfactory improvement rate and lower requirement for replacement, especially up to two times.
ABSTRACT
Introduction: Angiomyolipoma (AML) is the most prevalent renal mesenchymal neoplasm that almost always involves kidneys. Case presentation: We present a rare condition of retroperitoneal extra-renal angiomyolipoma which relapsed after 4 years that caused acute abdominal pain. Discussion: The liver is the most common site of extrarenal angiomyolipoma. Abdominal pain is the most common complaint of extra-renal angiomyolipoma. Computed tomography angiography is the best way for angiomyolipoma diagnosis and surgery and post-surgery chemotherapy is the way for its treatment. Conclusion: extrarenal angiomyolipoma is an extremely rare condition that patients should be followed up for over 5 years by appropriate radiologic imaging.
ABSTRACT
INTRODUCTION: Chronic, large, and old incisional hernias often lead to surgical complications and major hindrances during emergent laparotomies. The most challenging stages of the laparotomy in such cases occur during opening and fascial closure. CASE PRESENTATION: This article explains the novel surgical technique employed for the complex abdominal closure upon concluding an emergent laparotomy on a 68-year-old female patient. This innovative technique is appropriate for patients with contaminated abdominal cavities and scant fascia who require abdominal operations in cases where biological mesh is not available or is not a viable option. CONCLUSION: This surgical technique can help surgeons restrict abdominal contents and organs (particularly the bowel loops) and prevent migration out of the abdominal cavity during the early post-operative stages, hence, reducing post-surgical complications. The discussed surgical technique ensures that the abdominal fascia defect is limited using skin flaps. This defect later develops into a small hernia sac within a few weeks. Patients then need to have a secondary delayed elective operation on this significantly smaller sized hernia for repair using synthetic mesh.
