Introduction: Owing to the development of the laparoendoscopic single-site (LESS) procedure, transumbilical LESS nephroureterectomy (LESS-NU) has become a new approach for treating upper tract urothelial carcinoma.
Aim: The aim of this study is to introduce a modified LESS-NU procedure with bladder cuff excision for treating upper tract urothelial carcinoma (UTUC). We compared its clinical efficacy and postoperative outcomes in terms of follow-up time with traditional retroperitoneal laparoscopic nephroureterectomy (RL-NU).
Material And Methods: From May 2014 to May 2019, we performed nephroureterectomy on 42 patients using the retroperitoneal approach and a modified LESS approach. A retrospective analysis was conducted for the evaluation of the clinical and postoperative outcomes between the two groups.
Results: The study included 25 LESS-NU and 17 RL-NU patients. All the procedures were completed successfully. The LESS-NU group had a significantly shorter mean operative time than the RL-NU group (204.4 min, 236.18 min, p = 0.005). The differences in skin incision length (2.88 cm, 8.94 cm, p < 0.001) and oral analgesic dose (n = 1.12, n = 2.75, p < 0.001) between LESS-NU and RL-NU were statistically significant.
Conclusions: Modified LESS-NU is a feasible and safe procedure. Compared with the retroperitoneal laparoscopic approach, the single-site approach did not alter the patients' position. LESS-NU is a better procedure for treating UTUC than RL-NU in terms of cosmetic result and postoperative pain.

Background: Pancreatic cancer involving the pancreas neck and body often invades the retroperitoneal vessels, making its radical resection challenging. Multimodal treatment strategies, including neoadjuvant therapy, surgery, and postoperative adjuvant therapy, are contributing to a paradigm shift in the treatment of pancreatic cancer. This strategy is also promising in the treatment of pancreatic neck-body cancer.

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.

This case report describes a 66-year-old male diagnosed with a giant retroperitoneal lymphangioma, presenting with an abdominal mass confirmed via magnetic resonance imaging (MRI). Laparoscopic surgery was successfully performed to excise the mass, with histopathological examination confirming the diagnosis. The patient's postoperative recovery was uneventful, with no signs of recurrence or metastasis observed at the three-month follow-up.

: Retroperitoneal laparoscopic adrenalectomy (RLA) is one of two laparoscopic procedures used to treat benign and malignant adrenal diseases. Obesity in patients undergoing minimally invasive adrenal surgery is a frequently discussed topic. Our meta-analysis aimed to provide updated evidence by comparing intraoperative and perioperative outcomes on non-obese (NOb) and obese (Ob) patients who underwent RLA due to benign or malignant disease.

Background: Low-grade mucinous neoplasms typically originate from the appendix and are characterized by a lining of low-grade mucus-secreting columnar epithelial cells and smooth muscle. However, atypical origins can occur, as demonstrated in this case report.
Case Presentation: We present a case involving a 33-year-old male who, upon physical examination, was found to have an abdominal mass.
