A Large Retroperitoneal Lipoma Manifesting with a Femoral Hernia: A Case Report
2024A Case presentation of a 39-year-old female presented to our clinic with a soft, reducible mass in the femoral region, below and lateral to the pubic tubercle (imitating a femoral hernia). A magnetic resonance imaging (MRI) abdomen and a computerized tomography (CT) showed a sizable retroperitoneal lipomatous lobulated soft tissue lesion, measuring 10 cm × 10.8 cm × 24.5 cm.

2024Lymphatic Chyle Duct Injury and Identification During Laparoscopic Sleeve Gastrectomy Preventing Postoperative Chylous Ascites
2024A case presentation of intraoperative detection of an iatrogenic chyle duct injury during laparoscopic sleeve gastrectomy. The chyle duct injury was identified and managed by ligature, preventing postoperative chylous ascites.
View PublicationCan Incidental Gastric GISTs During Bariatric Surgeries Change the Primary Plan of Surgery? A Single Team Experience and a Systematic Review of Literature
2024As bariatric surgeries (BS) increase, more incidental findings are liable to be discovered. Incidental gastric gastrointestinal stromal tumors (GISTs) during BS can be found in around 0.7% of the cases. In this article, we have performed a systematic review of the literature and added our data to those of the review to review a conceptual treatment strategy to both improve patient outcomes and decrease the risk of overall cancer. With the rise of new bariatric techniques, we have proposed a new classification to BS to enhance our description of the treatment strategy.
View PublicationShould Incidentally Discovered Meckel’s Diverticulum During Bariatric Procedures Be Resected? Raising a Hypothesis for Future Research
2024The incidental discovery of Meckel’s diverticulum (MD) during bariatric surgeries has not been thoroughly studied due to the low prevalence of MD (approximately 2%) [1]. However, recent reports in the literature have highlighted the occurrence of MD during or after bariatric procedures (BS), raising questions about the necessity of resecting MD during BS. This article aims to draw attention to this concern within the IFSO and the obesity surgery community, urging further research and debate to establish evidence-based consensus.

A rare presentation of perforated Meckel’s diverticulum in a Litter’s hernia: A case report
2024A 46-year-old male patient with a history of appendectomy presented with fever and severe abdominal pain near the umbilicus. An umbilical hernia was felt as tense, tender, and irreducible. Computerized Tomography (CT) scans of the abdomen showed a loculated collection related to the umbilicus, and oral contrast was seen to extravasate into the collection. Surgical exploration revealed a perforated Meckel's diverticulum in an umbilical Littre's hernia.

View PublicationGIST in perforated Meckel's diverticulum
2023Although rare, Complicated Meckel's diverticulum (MD) is responsible for a variety of uncommon abdominal surgical emergency presentations. Because of these unique presentations, Meckel's diverticulum is a distinctive, peculiar astoundment in surgical practice. In this article, We reviewed previously published cases with both Gastrointestinal Stromal Tumors (GISTs) and MD to define the nature of both pathologies and their relation, the character, presentation, and timing of diagnosis of this rare coincidence. We illustrated this relation with a case of a perforated Meckel's diverticulum associated with multiple intestinal Gastrointestinal Stromal Tumors (GISTs) in a 58-year-old male presenting with features of acute appendicitis operated through a McBurney's incision.
View PublicationEvaluation of Laparoscopy Virtual Reality Training on the Improvement of Trainees’ Surgical Skills
2021Based on the three stages of evaluation, the virtual simulation with LapSim can help in teaching basic skills in the early stages of training and provide a good simulation for procedural operation for resident and fellowship training. The virtual simulation demonstrated significant results in most parameters; reducing operating time, improvement of tissue handling, instrument coordination, and reducing the incidence of complications resulting in an improvement in patient safety.
