Achieving margin-negative resection is crucial in treatment of solid pseudopapillary neoplasm (SPN) of the pancreas, while preserving the spleen during distal pancreatectomy is highly desirable in pediatric cases. Laparoscopic Warshaw procedure (Lap-WT) is invaluable when tumor involvement in splenic vessels complicates preservation. However, the feasibility of Lap-WT in pediatric patients remains contentious. This study presents the clinical outcomes of three pediatric SPN cases who underwent Lap-WT. The median age was 10 years, with a median tumor size of 50 mm. Lap-WT demonstrated successful outcomes with a median operation time of 311 min and blood loss of 12 mL. No postoperative complications occurred, with a median length of hospital stay of 8 days. Long-term follow-up showed mild thrombocytopenia and increased spleen volume in two cases, perigastric varices in one, with no bleeding complications. No instances of tumor recurrence were observed. Lap-WT emerges as a feasible approach for pediatric SPN, ensuring spleen preservation without compromising oncological outcomes.

Esophageal duplication cysts are rare congenital noncancerous growths. Symptoms of this disease are reported to be asymptomatic in approximately 70% but include respiratory symptoms such as coughing and difficulty breathing. Minimally invasive removal of these cysts without esophagectomy is typically recommended. However, when the cyst is situated in the upper mediastinum, surgical excision becomes technically challenging. Here, we report a case of an obese female patient with esophageal duplication cyst in the upper mediastinum who underwent successfully robotic-assisted complete removal of the cyst. A 50-year-old woman presented to a local clinic with a persistent cough and hoarseness lasting 4 months. A computed tomography scan revealed a large cystic tumor in the upper mediastinum, causing displacement of the trachea. The resection of the cystic tumor was safely performed with robotic assistance. The use of robotic system for the removal of esophageal duplication cyst is technically safe and feasible.

In this era of endoscopic surgery, feedback from recorded surgical videos is useful and efficient; therefore, effective methods of obtaining this feedback are needed. We analyzed surgical videos using motion analysis software and verified the usefulness of visualizing and objectively evaluating surgical procedures. We measured the grasping and traction angles of the vascular sheath when using forceps and the trajectory of the forceps tip for the upper pulmonary vein during right upper lobectomy during video-assisted thoracoscopic surgery performed by three trainers and trainees. Compared with the trainers, the trainees exhibited insufficient traction of the vascular sheath, performed many slow and unnecessary manipulations, and sometimes performed sudden and fast movements. By visualizing the surgical procedures, the trainee will be better able to identify dangerous or futile movements. It may also make it easier to objectively recognize improvements in one's technique. Motion analysis software could allow for efficient surgical education and self-learning.

Thanatophoric dysplasia (TD) is a rare and severe type of skeletal dysplasia. Typical clinical findings include macrocephaly, shortening of the four limbs, underdeveloped lungs, and thoracic hypoplasia. Neonates with TD develop severe respiratory problems due to thoracic hypoplasia and require respiratory management for survival. Despite the resolution of respiratory problems, long-term survival cases are rare. Previous studies have reported that surgical procedures in patients with TD are limited to those necessary for survival, including tracheostomy, laminectomy, and ventricular shunt. A 1-year-old boy with TD was treated with laparoscopic herniorrhaphy. To the best of our knowledge, this is the first report of TD treated with laparoscopic procedure.

Laparoscopic fenestration is the preferred treatment for symptomatic splenic cysts because it is curative and spleen-sparing. We report a case of a 25-year-old female who underwent laparoscopic fenestration for a giant splenic cyst using a single-incision plus one-port approach. She presented to our hospital with repeated vomiting. Imaging showed a 23 × 18 cm splenic cyst with no solid components, strongly compressing the stomach to the right side. Laparoscopic fenestration was initiated through a 2.5-cm umbilical incision, and a 5-mm port was added in the left abdomen intraoperatively. The drain placement was deemed necessary to prevent abscess formation and post-operative bleeding because of a thick cyst component and unexpectedly thick wall. Splenic cysts are typically benign and commonly develop in young people, hence, organ preservation and cosmetic results are crucial. Laparoscopic fenestration using single-incision plus one-port is considered to be an appropriate procedure for giant splenic cysts with non-serous contents.
