Introduction: In laparoscopic surgery, marking of tumor location has been gaining importance. Tattoo marking has been often used but the technique carries the risk of accidental peritoneal scattering or other organ injury. We have been involved in the development of a novel fluorescent clip for marking tumor sites and supposed that its usage would reduce risks related to other marking methods.
Case Presentation: A 52-year-old man was diagnosed with sigmoid colon cancer and polyp, and was scheduled for laparoscopic sigmoidectomy. On the day before operation, fluorescent clips (ZEOCLIP FS: Zeon Medical co, Ltd, Tokyo) were endoscopically placed around the tumor and polyp sites, 4 clips for each lesion attached every 90 degrees within the colonic lumen, respectively. During the operation, locations of the fluorescent clips were easily confirmed using a full-color fluorescent laparoscope, VISION SENSE (Medtronic Co., U.S.). Curative operation was performed accordingly with the preoperative pathological and radiological findings. The postoperative course was uneventful.
Discussion: Locations of intraluminally placed fluorescent clips were clearly and easily recognized through the serosal layer of the intestinal wall using a fluorescent laparoscope. Complications related to dye scattering or intestinal wall/other organ perforation were not observed suggesting that future incorporation of this tumor site marking technique into laparoscopic surgery might be beneficial.
Conclusion: The fluorescent marking clips were easily placed and recognized with a fluorescent laparoscope. This method is expected to be safe and risks of accidental puncture related to tattoo marking method can be reduced or almost eliminated.

Background: Liver malignancies present substantial challenges to surgeons due to the extensive hepatic resections required, frequently resulting in posthepatectomy liver failure. Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was designed to increase the resectable liver volume, yet it is associated with significant mortality and morbidity rates. Recently, minimally invasive techniques have been incorporated into ALPPS, with the potential to improve the procedure's safety profile whilst maintaining efficacy.

Pancreatic surgery is considered one of the most challenging interventions by many surgeons, mainly due to retroperitoneal location and proximity to key and delicate vascular structures. These factors make pancreatic resection a demanding procedure, with successful rates far from optimal and frequent postoperative complications. Surgical planning is essential to improve patient outcomes, and in this regard, many technological advances made in the last few years have proven to be extremely useful in medical fields.

Purpose: This article critically examines long-standing groin pain (LSGP) in physically active adults related to sports overload by analyzing terminology, pathophysiology, and treatment.
Method: This review is based on data from over 10,000 patients managed through a multidisciplinary algorithm. (LSGP) has been variably labeled, using terms that have led to inconsistencies in understanding its origin and management.

The synchronous occurrence of pancreatic neuroendocrine neoplasm (PNEN) and clear cell renal cell carcinoma (ccRCC) in one patient is extremely rare. Synchronous resection of both tumours is preferred over a two-stage procedure if possible. The robotic da Vinci Xi platform allows for multi-quadrant surgery with oncological outcomes comparable to those of laparoscopic or open surgery.

Technical difficulties are often encountered in a laparoscopic cholecystectomy where a tense/distended/ turgid gall bladder prevents the surgeon from grasping the gall bladder properly which therefore necessitates the decompression of the turgid gall bladder. However, even if intraoperative decompression is done, the spillage of remnant stones, bile or fluid from the gall bladder is a possibility which can lead to undue complications. This is where following the simple technique of using a gauze piece with a radio-opaque marker to occlude the decompression puncture site helps in performing a safe decompression thereby preventing bile, fluid or stone spillage.
