Hand Sewn Anastomosis Skill Acquisition and In Vivo Transfer Using 3D-Printed Small Bowel Simulator.

Introduction: General surgery residents need to master the hand-sewn bowel anastomosis (HSBA) technique. However, practice opportunities outside of the operating room are rare, and commercial simulators are often costly. The objective of this study is to assess the efficacy of a new, affordable silicone small bowel simulator, made with a three-dimensional (3D) printed mold, as a training tool to learn this technique.

Oversized lotus petal flap for reconstruction of extensive perineal defects following abdomino perineal resection.

Introduction: Abdominoperineal resection (APR) of low rectal and anal tumors are performed for optimal oncological outcome but results in large defects in the perineum. Although vertical rectus abdominus (VRAM) flap is commonly employed for extensive perineal reconstruction, donor site morbidity remains problematic. The fascio-cutaneous "lotus petal" flap is an appealing option for reconstructing perineal defects as it may benefit from less donor site morbidity than other techniques.

Partial DIEP flap loss in a patient with history of abdominal liposuction.

Classically, history of prior abdominal liposuction has been considered a relative contraindication for breast reconstruction using deep inferior epigastric perforator (DIEP) flap. The rationale for this is based on the fact that liposuction can possibly damage perforating vessels, which could compromise flap survival. However, multiple recently published reports have shown that imaging using CT angiography or colour Duplex ultrasonography could be used to accurately assess the adequacy of the perforating vessels before DIEP flap harvest.

Malignant phyllodes tumors of the breast: A comprehensive literature review.

Malignant phyllodes tumors (MPT) have always been a great deal of controversy among fibroepithelial tumors of the breast. Genetics, histopathology, and tumor behavior on the cellular scale shape their extent of aggressiveness. Diagnosis is based on radiological and pathological findings.

Toothpick ingestion and migration into the liver through the colonic hepatic flexure: case presentation, management, and literature review.

The approach to toothpick ingestion and its complications should not be underestimated. The surgeon should be prepared for life-threatening situations such as major vascular involvement, as well as highly specialized and technically challenging procedures, when the hepatic hilum is involved for instance. Referral to tertiary centers is sometimes mandatory.
