BACKGROUND: Pancreaticoduodenectomy is associated with an incidence of postoperative complications of approximately 41%. One of the most severe complications is a postoperative pancreatic fistula. The exact cause of postoperative fistula development is still unknown, but it appears to be multifactorial. Proper perfusion of pancreatic remnant is essential for the healing of pancreaticojejunostomy. To date, there is no method to reliably evaluate the vascular supply of the remnant. One of the methods for the assessment of organ perfusion is the indocyanine green fluorescence. This study aims to determine if indocyanine green fluorescence is a reliable method to measure the perfusion of the post-resection pancreatic remnant. The secondary outcome is to determine if intraoperative evaluation of the vascular supply of the post-resection remnant may predict the increased risk of postoperative pancreatic fistula development. METHODS: This study is designed as a prospective, observational study. All consecutive patients undergoing open or robotic pancreaticoduodenectomies at our department during the 1st May 2024-31st December 2026 period will be enrolled. The exclusion criteria are an allergy to indocyanine green and refusal by the patient. The adequacy of the vascular supply of the post-resection pancreatic remnant will be intraoperatively evaluated using a fluorescence detector. Patients will be divided into two groups: Those with high risk of pancreatic fistula development and those with low risk. The incidence of pancreatic fistulas in both groups is to be compared. Postoperative data including morbidity, mortality, hospital stay, intensive care unit stay and postoperative fistula development will be collected. DISCUSSION: If an intraoperative assessment of the perfusion of post-resection pancreatic remnant using indocyanine green is proven to be a suitable method to estimate the increased risk of the pancreatic fistula, the list of the existing known risk factors could be expanded. In the most high-risk patients the modification of the surgical procedure could be considered. TRIAL REGISTRATION: Number: NCT06198400 ClinicalTrials.Gov. Date 08.01.2024.

Hepatopancreatobiliary surgery belongs to one of the most complex fields of general surgery. An intricate and vital anatomy is accompanied by difficult distinctions of tumors from fibrosis and inflammation; the identification of precise tumor margins; or small, even disappearing, lesions on currently available imaging. The routine implementation of ultrasound use shifted the possibilities in the operating room, yet more precision is necessary to achieve negative resection margins. Modalities utilizing fluorescent-compatible dyes have proven their role in hepatopancreatobiliary surgery, although this is not yet a routine practice, as there are many limitations. Modalities, such as photoacoustic imaging or 3D holograms, are emerging but are mostly limited to preclinical settings. There is a need to identify and develop an ideal contrast agent capable of differentiating between malignant and benign tissue and to report on the prognostic benefits of implemented intraoperative imaging in order to navigate clinical translation. This review focuses on existing and developing imaging modalities for intraoperative use, tailored to the needs of hepatopancreatobiliary cancers. We will also cover the application of these imaging techniques to theranostics to achieve combined diagnostic and therapeutic potential.

Úvod: Neurinomy jsou skupinou dobře diferencovaných benigních tumorů vycházejících ze Schwannových buněk periferních nervů. Jejich výskyt v oblasti pánve je vzácný. Expandující neurinomy se mohou projevovat pestrou neurologickou symptomatologií nebo útlakem orgánů pánve. Kazuistika: Autoři prezentují případ 60leté pacientky s objemným symptomatickým hluboce uloženým neurinomem pánve. Nemocná podstoupila roboticky asistovanou operaci s kompletní exstirpací tumoru. Pooperační průběh byl nekomplikovaný s dimisí druhý pooperační den. Histologicky byla potvrzena diagnóza neurinomu. Pacientka je 11 měsíců od operace bez obtíží a bez neurologického deficitu. Závěr: Roboticky asistovaná operace umožňuje bezpečnou a efektivní chirurgickou léčbu ve špatně přístupných anatomických prostorech. Magnetická rezonance je obligatorní metodou při předoperačním zobrazení neurogenních nádorů. V případě průkazu neurinomu není histologická verifikace doporučována. Nutná je multidisciplinární spolupráce s dedikovaným týmem se zkušeností s miniinvazivní pánevní chirurgií.

Introduction: Schwannomas are a group of well differentiated benign tumors originating from the Schwann cells of the peripheral nervous system. Their localization in the pelvis is very rare. Schwannomas with expansive growth can cause wide neurologic symptoms or oppression of pelvic organs. Case report: The authors present a case study of a 60-year-old woman with a large, symptomatic deep pelvic schwannoma. The patient underwent robotic-assisted surgery resulting in complete tumor extirpation. The patient’s postoperative course was uneventful with a total of two hospitalization days. The diagnosis of a schwannoma was confirmed by histopathologic analysis. At 11-month follow-up surveillance the patient did not present any neurological deficit or other symptoms. Conclusion: Robotic-assisted surgery allows safe and effective surgical treatment in difficult-to-access anatomical areas. Magnetic resonance imaging is required for preoperative imaging of neurogenic tumors. Histological verification is not recommended in cases where evidence of a schwannoma is found. Multidisciplinary cooperation of a dedicated team experienced in minimally invasive pelvic surgery is necessary.
