BackgroundThis study compared the surgical and urinary functional outcomes in patients with muscle‐invasive bladder cancer (MIBC) who underwent robot‐assisted radical cystectomy (RARC) followed by intracorporeal ileal neobladder reconstruction (ICNB) to those in patients who underwent minimum incision endoscopic radical cystectomy (MIE‐RC) followed by extracorporeal ileal neobladder reconstruction (ECNB).Materials and MethodsThis study reviewed the clinical records of 153 consecutive MIBC patients who underwent neoadjuvant chemotherapy followed by radical cystectomy and ileal neobladder reconstruction.ResultsThe operative time in the ICNB group was significantly longer than that in the ECNB group. The median estimated blood loss was significantly less in the ICNB group than in the ECNB group. The neobladder capacity gradually increased in both groups. The maximum neobladder pressure and urethral closure pressure gradually improved in both groups.ConclusionOur initial experience with ICNB was favourable, with acceptable surgical and urinary functional outcomes.
Background:
Doege-Potter syndrome presents as solitary fibrous tumors and non-islet cell tumor hypoglycemia (NICTH). Here, we report a case of Doege-Potter syndrome in which retroperitoneal tumor resection was performed with continuous intraoperative blood glucose monitoring.
Case Presentation:
The patient was a 37-year-old healthy man with no relevant medical history. They were brought to the emergency room because of defecation difficulties and incontinence caused by hypoglycemia, and a tumor measuring 10 × 12 × 9 cm was found in the right kidney. High-molecular-weight insulin-like growth factor-II (IGF-II) was detected in the blood, indicating an IGF-II-producing tumor with NICTH. The patient underwent tumor resection, and the pathological results indicated a solitary fibrous tumor of retroperitoneal origin. Thus, retroperitoneal primary Doege-Potter syndrome was diagnosed. Continuous blood glucose monitoring was performed intraoperatively, and no hypoglycemic attacks occurred; insulin secretory abnormalities improved immediately after surgery. Previous studies suggest that IGF-II is metabolized in a few hours. Therefore, serum IGF-II levels were analyzed one week and one month postoperatively; the levels were within the normal range at both time points. Two years have passed since the surgery without recurrence.
Conclusions:
Doege-Potter syndrome of retroperitoneal primary origin is rare. Furthermore, continuous intraoperative blood glucose monitoring was performed during surgery; thus, we report blood glucose level trends for the first time. This case highlights that this type of surgery can be performed safely without special blood glucose adjustments and that insulin secretion resumes soon after surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
