Non-surgical acute cholecystitis: 2 cases of gallbladder rupture after internal endoscopic or percutaneous diversion

Gallbladder rupture is a rare but serious complication of acute cholecystitis. We describe two cases of acute cholecystitis in patients not candidate for surgery that underwent internal biliary drainage with endoscopic and percutaneous approach, respectively. Both experienced gallbladder rupture&nbsp; in the postoperative period. The complication occurred after percutaneous internal drainage was treated conservatively, whereas the latter occurred after the endoscopic maneuver required an external percutaneous approach. After a brief revision of the literature about the interventional management of acute cholecystitis, the Authors discuss the possible reasons of galbladder rupture.&nbsp;</p

From PVE to HVE to fully laparoscopic rescue ALPPS: a case report of multidisciplinary management of giant HCC

Different strategies have been used to induce preoperative liver hypertrophy and reduce the risk of postoperative liver failure. Those have included both radiological-interventional and surgical strategies, such as portal and hepatic vein embolization, 2-stage hepatectomy and associated liver partition with portal vein ligation for staged hepatectomy (ALPPS). Herein, we describe the case of a patient with a large right liver hepatocellular carcinoma not amenable to liver transplantation, with HBV-related chronic hepatitis and a small future liver remnant (FLR), who underwent a multistep approach to ensure a safe major laparoscopic resection with an adequate FLR

Laparoscopic Right Hemihepatectomy after Future Liver Remnant Modulation: A Single Surgeon’s Experience

Background: Laparoscopic right hemihepatectomy (L-RHH) is still considered a technically complex procedure, which should only be performed by experienced surgeons in specialized centers. Future liver remnant modulation (FLRM) strategies, including portal vein embolization (PVE), and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), might increase the surgical difficulty of L-RHH, due to the distortion of hepatic anatomy, periportal inflammation, and fibrosis. Therefore, this study aims to evaluate the safety and feasibility of L-RHH after FLRM, when compared with ex novo L-RHH. Methods: All consecutive right hemihepatectomies performed by a single surgeon in the period between October 2007 and March 2023 were retrospectively analyzed. The patient characteristics and perioperative outcomes of L-RHH after FLRM and ex novo L-RHH were compared. Results: A total of 59 patients were included in the analysis, of whom 33 underwent FLRM. Patients undergoing FLRM prior to L-RHH were most often male (93.9% vs. 42.3%, p 2 (45.5% vs. 9.5%, p = 0.006), and underwent a two-stage hepatectomy (45.5% vs. 3.8% p < 0.001). L-RHH after FLRM was associated with longer operative time (median 360 vs. 300 min, p = 0.008) and Pringle duration (31 vs. 24 min, p = 0.011). Intraoperative blood loss, unfavorable intraoperative incidents, and conversion rates were similar in both groups. There were no significant differences in length of hospital stay and 30-day overall and severe morbidity rates. Radical resection margin (R0) and textbook outcome rates were equal. One patient who underwent an extended RHH in the FLRM group deceased within 90 days of surgery, due to post-hepatectomy liver failure. Conclusion: L-RHH after FLRM is more technically complex than L-RHH ex novo, as objectified by longer operative time and Pringle duration. Nevertheless, this procedure appears safe and feasible in experienced hands

Prospective Assessment of Tumour Burden and Bone Disease in Plasma Cell Dyscrasias Using DW-MRI and Exploratory Bone Biomarkers

Novel biomarkers for tumour burden and bone disease are required to guide clinical management of plasma cell dyscrasias. Recently, bone turnover markers (BTMs) and Diffusion-Weighted Magnetic Resonance Imaging (DW-MRI) have been explored, although their role in the prospective assessment of multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) is unclear. Here, we conducted a pilot observational cohort feasibility study combining serum BTMs and DW-MRI in addition to standard clinical assessment. Fifty-five patients were recruited (14 MGUS, 15 smouldering MM, 14 new MM and 12 relapsed MM) and had DW-MRI and serum biomarkers (P1NP, CTX-1, ALP, DKK1, sclerostin, RANKL:OPG and BCMA) measured at baseline and 6-month follow-up. Serum sclerostin positively correlated with bone mineral density (r = 0.40&minus;0.54). At baseline, serum BCMA correlated with serum paraprotein (r = 0.42) and serum DKK1 correlated with serum free light chains (r = 0.67); the longitudinal change in both biomarkers differed between International Myeloma Working Group (IMWG)-defined responders and non-responders. Myeloma Response Assessment and Diagnosis System (MY-RADS) scoring of serial DW-MRI correlated with conventional IMWG response criteria for measuring longitudinal changes in tumour burden. Overall, our pilot study suggests candidate radiological and serum biomarkers of tumour burden and bone loss in MM/MGUS, which warrant further exploration in larger cohorts to validate the findings and to better understand their clinical utility
