Is It Safe to Operate without Frozen Section Biopsies in Short-Segment Hirschsprung's Disease? An Overview of 60 Cases.

Background: Advancements in surgical management in a single-stage procedure made intraoperative frozen section biopsies critical for determining of level of resection to avoid the potential risk of leaving a retained aganglionic segment. However, in most low-income countries, due to the lack of this facility, the surgeon's intraoperative judgment is used for the determination of the resection level. Objective: This study aims to evaluate the accuracy of determining the level of bowel resection in short-segment Hirschsprung's disease based on macroscopic changes. Materials and methods: Intraoperative macroscopic evaluations were assessed using postoperative microscopic findings to determine whether the surgeons' intraoperative judgments were accurate in determining the level of bowel resection in 60 cases of operated short-segment Hirschsprung's disease. In addition, Pearson's correlation coefficient was used to determine whether the sensitivity and specificity of both methods were significantly correlated. Results: The microscopic results showed that the level of resection based on the macroscopic evaluation was performed in normally ganglionated segment in cases of short-segment Hirschsprung's disease. Conclusions: Macroscopic intraoperative assessment by an experienced surgeon is highly accurate method of determining the level of bowel resection in short-segment HSCR.

Acquired intra abdominal testis due to adhesions after necrotizing enterocolitis.

Undescendent testis happens usually due to the stagnation during testicular descends. Stagnation of a testicle in the abdomen may be the target of adhesions with intestinal segments. Our case report a very rare variant of acquired intra-abdominal cryptorchidism due to adhesions after necrotizing enterocolitis. Newborn baby after NEC has a significant risk of developing intraperitoneal adhesions. In this report we will describe a case of previously palpable testis in the inguinal canal at neonatal age which was pulled inside the abdomen at seventh month of age through adhesions between test and the segment of sigmoid colon after NEC.

Renal artery thrombosis as a long-term complication of COVID-19.

Coronavirus disease 2019 (COVID-19) has been extensively associated with microvascular and macrovascular thrombosis. Several reports have demonstrated a link between COVID-19 and pulmonary embolism, deep vein thrombosis, myocardial infarction, stroke, and aortic thrombosis. Renal artery thrombosis is of special interest because of its life-threatening consequences, such as acute kidney injury and renal infarction. We present a case of left renal artery thrombosis as a long-term complication of COVID-19. Moreover, we demonstrate the effectiveness of interventional radiology to regain vascularization of the affected kidney.
