Pre-operative interventional radiology: could it have a role before complex laparoscopic surgery?
2021
Bleedings occurring during a surgical intervention can be caused by haemostatic defects, but they are generally due to ineffective local haemostasis. Current coagulation systems may not be sufficient to achieve a good haemostasis, causing, at the same time, tissue dama-ge. Furthermore, the availability of such devices does not eliminate difficulties linked to the isolation of vessels, a crucial step of surgical procedures that require the removal of an organ or part of it, in case of inflammation or neoplasm. This difficulty is even more evident, and weighs more on operative times, when the surgeon engages with video-assisted surgery, where anatomical structures are difficult to detect and …

Impact of Acute Hemoglobin Falls in Heart Failure Patients: A Population Study
2020
Aims: This study assessed the impact of acute hemoglobin (Hb) falls in heart failure (HF) patients. Methods: HF patients with repeated Hb values over time were included. Falls in Hb greater than 30% were considered to represent an acute episode of anemia and the risk of hospitalization and all-cause mortality after the first episode was assessed. Results: In total, 45,437 HF patients (54.9% female, mean age 74.3 years) during a follow-up average of 2.9 years were analyzed. A total of 2892 (6.4%) patients had one episode of Hb falls, 139 (0.3%) had more than one episode, and 342 (0.8%) had concomitant acute kidney injury (AKI). Acute heart failure occurred in 4673 (10.3%) patients, represent…
The use of operative ultrasonography for the localization of renal calculi.
1987
The ultrasonically guided nephrotomy technique using B-scanning to identify the localization of stones and Doppler sonography to identify avascular parenchymal areas for nephrotomies allows for transparenchymal stone removal without the need for renal artery clamping and renal cooling. In 175 procedures the average blood loss was 1,350 ml and the rate of residual stones requiring a secondary intervention was 2.8%. Despite the advent of new noninvasive treatment modalities, this technique is still applied in 23% of staghorn stones.
Hemostasis in brain tumor surgery using the Aquamantys system
2014
Background: Adequate hemostasis in cranial and spinal tumor surgery is of paramount importance in neurosurgical practice. Generalized ooze bleeding from the surgical walls cavity, coming from neoplastic vessels or nervous tissue, may be problematic. Recent technical advances have dramatically reduced intraoperative complications related to blood loss. Several techniques are usually employed to control hemostasis in tumor surgery, including preoperative embolization, intraoperative hypotension, electrical coagulation, and local application of fibrin sealants or hemostatic matrix, which influence coagulation. Material/Methods: Our aim in this study was to evaluate the efficacy and the safety …
Rate of Post-Operative Pancreatic Fistula after Robotic-Assisted Pancreaticoduodenectomy with Pancreato-Jejunostomy versus Pancreato-Gastrostomy: A R…
2021
Background: Different techniques of pancreatic anastomosis have been described, with inconclusive results in terms of pancreatic fistula reduction. Studies comparing robotic pancreaticogastrostomy (PG) and pancreaticojejunostomy (PJ) are scarcely reported. Methods: The present study analyzes the outcomes of two case-matched groups of patients who underwent PG (n = 20) or PJ (n = 40) after pancreaticoduodenectomy. The primary aim was to compare the rate of post-operative pancreatic fistula. Results: Operative time (375 vs. 315 min, p = 0.34), estimated blood loss (270 vs. 295 mL, p = 0.44), and rate of clinically relevant post-operative pancreatic fistula (12.5% vs. 10%, p = 0.82) were simil…
Tangential Venous Resections during Robotic-Assisted Pancreaticoduodenectomy: the Results of a Case Series (with Video)
2020
Introduction: Despite the potential advantages in terms of microdissection and microsuturing capabilites, the robotic approach for borderline resectable pancreatic cancer is scarcely reported. Methods: We report our technique for a robotic-assisted pancreaticoduodenectomy with tangential Portal/ Superior Mesenteric Vein resection/reconstruction (RPD PV/SMV).We also compared the surgical outcomes of eight consecutive patients undergoing RPD PV/SMV with that of sixty patients who underwent robotic-assisted pancreaticoduodenectomy (RPD) in the same period of time. Results: A total of eight consecutive patients underwent RPD PV/SMV. We observed an increased estimated blood loss (550 vs 280 mL, …
Ultrasound as first line step in anaemia diagnostics
2019
This review covers the role of ultrasonography as an essential non-invasive diagnostic approach when facing patients with anemia, a common clinical problem. Abdomen ultrasound is well recognized as a first-line examination in the setting of blood loss, both acute and chronic. Less is clear about the additional opportunities, given by ultrasound in anemia, due to the many other possible causes.
 Here we provide information on the utility of ultrasound in different contexts and a practical guide for clinicians facing anemic patients
Laparoscopic minor pancreatic resections (enucleations/atypical resections). A long-term appraisal of a supposed mini-invasive approach
2012
A b s t r a c t Introduction: A few retrospective, small, often multicentric studies show encouraging results of laparoscopic minor pancreatic surgery, but do not allow for an evaluation of feasibility and effectiveness. Aim: Evaluation of the results of laparoscopic minor pancreatic resections (LMPR), including atypical resections and enucleations. Material and methods: The outcome of all consecutive patients undergoing LMPR in a tertiary care university hospi- tal specializing in the laparoscopic approach to solid organs (I.M.M., Paris - France) was retrospectively evaluated by the analysis of operating time, blood loss, conversion, morbidity, stay and late outcome. Results: Thirty-three …
Die endoskopische retroperitoneale Adrenalektomie
2008
Aim of study To determine prospectively in consecutive patients the value of endoscopic retroperitoneal adrenalectomy. Patients and methods Between March 1994 and March 1995, endoscopic adrenalectomy via a retroperitoneal approach was performed in eleven patients (three men, eight women; median age 61 [48-73] years), unilateral in nine, bilateral in two. The procedure was indicated if the adrenal tumour was thought to be benign and no larger than 5 cm in diameter (two adrenal and two central Cushing's syndromes; three incidentally detected adrenal adenomas, two phaeochromocytomas, two Conn adenomas). Results Twelve of the 13 procedures were successfully performed. In one case the primary in…
