A core set of quality performance indicators for HPB procedures: a global consensus for hepatectomy, pancreatectomy, and complex biliary surgery.

BACKGROUND: Surgery for hepatopancreaticobiliary (HPB) conditions is performed worldwide. This investigation aimed to develop a set of globally accepted procedural quality performance indicators (QPI) for HPB surgical procedures. METHODS: A systematic literature review generated a dataset of published QPI for hepatectomy, pancreatectomy, complex biliary surgery and cholecystectomy. Using a modified Delphi process, three rounds were conducted with working groups composed of self-nominating members of the International Hepatopancreaticobiliary Association (IHPBA). The final set of QPI was circulated to the full membership of the IHPBA for review. RESULTS: Seven "core" indicators were agreed for hepatectomy, pancreatectomy, and complex biliary surgery (availability of specific services on site, a specialised surgical team with at least two certified HPB surgeons, a satisfactory institutional case volume, synoptic pathology reporting, undertaking of unplanned reintervention procedures within 90 days, the incidence of post-procedure bile leak and Clavien-Dindo grade ≥III complications and 90-day post-procedural mortality). Three further procedure specific QPI were proposed for pancreatectomy, six for hepatectomy and complex biliary surgery. Nine procedure-specific QPIs were proposed for cholecystectomy. The final set of proposed indicators were reviewed and approved by 102 IHPBA members from 34 countries. CONCLUSIONS: This work presents a core set of internationally agreed QPI for HPB surgery.

Long-term Outcomes After Laparoscopic, Robotic, and Open Pancreatoduodenectomy for Distal Cholangiocarcinoma: An International Propensity Score-matched Cohort Study.

OBJECTIVE: This study aimed to compare surgical and oncological outcomes after minimally invasive pancreatoduodenectomy (MIPD) versus open pancreatoduodenectomy (OPD) for distal cholangiocarcinoma (dCCA). BACKGROUND: A dCCA might be a good indication for MIPD, as it is often diagnosed as primary resectable disease. However, multicenter series on MIPD for dCCA are lacking. METHODS: This is an international multicenter propensity score-matched cohort study including patients after MIPD or OPD for dCCA in 8 centers from 5 countries (2010-2021). Primary outcomes included overall survival (OS) and disease-free interval (DFI). Secondary outcomes included perioperative and postoperative complications and predictors for OS or DFI. Subgroup analyses included robotic pancreatoduodenectomy (RPD) and laparoscopic pancreatoduodenectomy (LPD). RESULTS: Overall, 478 patients after pancreatoduodenectomy for dCCA were included of which 97 after MIPD (37 RPD, 60 LPD) and 381 after OPD. MIPD was associated with less blood loss (300 vs 420 mL, P =0.025), longer operation time (453 vs 340 min; P <0.001), and less surgical site infections (7.8% vs 19.3%; P =0.042) compared with OPD. The median OS (30 vs 25 mo) and DFI (29 vs 18) for MIPD did not differ significantly between MIPD and OPD. Tumor stage (Hazard ratio: 2.939, P <0.001) and administration of adjuvant chemotherapy (Hazard ratio: 0.640, P =0.033) were individual predictors for OS. RPD was associated with a higher lymph node yield (18.0 vs 13.5; P =0.008) and less major morbidity (Clavien-Dindo 3b-5; 8.1% vs 32.1%; P =0.005) compared with LPD. DISCUSSION: Both surgical and oncological outcomes of MIPD for dCCA are acceptable as compared with OPD. Surgical outcomes seem to favor RPD as compared with LPD but more data are needed. Randomized controlled trials should be performed to confirm these findings.

Portal vein thrombosis following elective laparoscopic splenectomy: incidence and analysis of risk factors.

BACKGROUND: Minimally invasive splenectomy is now well established for a wide range of pathologies. Portal vein thrombosis (PVT) is increasingly being recognised as a complication of splenectomy. The aim was to determine the incidence and risk factors for PVT after laparoscopic splenectomy. METHODS: All cases of elective laparoscopic splenectomy performed from 1993 to 2020 were reviewed. Parameters recorded included demographics, diagnostic criterion and post-operative outcomes. Data were analysed using Minitab V18 with a p < 0.05 considered significant. RESULTS: 210 patients (103 female, 107 male) underwent laparoscopic splenectomy (14 to 85 years). A major proportion of cases were performed for ITP (n = 77, p = 0.012) followed by lymphoma (n = 28), indeterminate lesions (n = 21) and myelofibrosis (n = 19). Ten patients developed symptomatic portal vein thrombosis (4.8%). Patients presented most commonly with pain and fever and diagnosis was confirmed by computed tomography (CT) or ultrasonography (USS). There were 10 conversions (4.8%) to open and two postoperative deaths, one from PVT and one from pneumonia. The remaining nine patients were successfully treated with anticoagulation. Of 19 patients with myelofibrosis, six patients developed PVT (p = 0.0002). Patients who developed PVT had significantly greater specimen weights (1773 g vs 348 g, p < 0.001). Forty-three patients had a specimen weight of 1 kg or greater, and of these 9 developed portal vein thrombosis (21%), versus one with PVT of 155 with a specimen weight of less than 1 kg (p < 0.0001). Myelofibrosis (p = 0.0039), specimen weight (p < 0.001) and mean platelet count (p = 0.0049) were predictive of PVT. CONCLUSION: A high index of suspicion for this complication should be maintained and prompt treatment with anticoagulation. High-risk patients should be considered for prophylactic anticoagulation and routine imaging of the portal vein.

Large size and haemorrhage are not contraindications to laparoscopic resection of hepatocellular adenoma.

BACKGROUND: Hepatocellular adenoma (HCA) is a hepatocyte derived neoplastic lesion with an increasing incidence and a strong association with oestrogen therapy. Laparoscopic resection has proven safe for small, non-ruptured lesions whilst its use for large adenomas (≥10 cm) and cases of haemorrhage requires further investigation. METHODS: All patients undergoing liver resection for HCA at the Royal Brisbane Hospital between January 2003 and April 2018 were analysed. Ethics approval was obtained. RESULTS: Thirty-three laparoscopic and three open resections were performed in 35 patients, all female, with a median age of 35 years (range 14-75). Nine laparoscopic resections were performed for large adenomas (≥10 cm) and 17 laparoscopic resections were performed for adenomas of intermediate size (5-9.9 cm). Only one conversion to open surgery was required for an intermediate sized tumour. Haemorrhage, either intratumoural, intraparenchymal or free intraperitoneal was the indication for resection in six of the 33 laparoscopic cases. Median operative time was 143 and 266 min for laparoscopically resected intermediate and large lesions, respectively. The median length of stay was 5 days (range 4-9) and no major complications were observed in the laparoscopic group. ß-catenin mutation was seen in four of nine large adenomas whereas the inflammatory subtype constituted 11 of 17 intermediate sized lesions. CONCLUSION: Laparoscopic surgery has been demonstrated to be safe for the resection of HCA in this group of patients. Importantly, haemorrhage and/or large size were not barriers to laparoscopic resection.

Emergency Department management of Colles-type fractures: a prospective cohort study.

OBJECTIVE: To assess radiographic outcomes from ED reduction of Colles-type fractures. DESIGN: Prospective cohort. SETTING: One tertiary hospital in Western Australia. PARTICIPANTS: All patients (184) between ages 21-85 years, presenting to ED with Colles-type fractures between 1 April 2006 to 31 July 2008. Fractures were divided into two groups. Those with 15 degrees dorsal angulation were classified as 'displaced'. MAIN OUTCOME MEASURES: Radiographic analysis of the dorsal angle on post-reduction and 6 week post-fracture X-rays. A combined end-point of poor outcome, as defined by either poor radiological result and/or progression to surgery. RESULTS: In the group of patients with displaced fractures, 69 of 114 (61%) went on to have an operation or a poor radiographic outcome versus 8 of 48 (17%) in the group with minimally displaced fractures, an absolute difference of 44% (95% CI 30-57%). Patients who had a minimally displaced fracture with an adequate reduction went on to have a satisfactory 6 week X-ray in 37 of 43 cases (86%; 95% CI 75-96%). Patients who had a displaced fracture and an adequate reduction had a satisfactory 6 week X-ray in 42 of 86 cases (49%; 95% CI 38-59%). Patients who had a displaced fracture and an inadequate reduction had a satisfactory 6 week X-ray in only 3 of 22 cases (14%; 95% CI 0-28%). CONCLUSION: The study highlights the importance of the initial 'on arrival' and 'post-reduction' X-rays in the ED. Displaced fractures are more likely to go onto poor outcome, as are inadequately reduced fractures. Medical officers working in ED should be aware of the importance of measuring the dorsal angle. They should be referring patients with >15 degrees dorsal angulation to orthopaedics early. Reduction should not be accepted until the dorsal angle has been adequately corrected.
