RESUMO

BACKGROUND/AIM: Locally advanced pancreatic cancer (LAPC) of the pancreatic body involving the celiac axis requires specialized treatment, including a subtotal distal pancreatectomy (SDP) with resection of the celiac axis (Appleby procedure). This study aimed to examine the value of the Appleby procedure, in current individualized treatment approaches, and to define its possible therapeutic impact for patients with LAPC. PATIENTS AND METHODS: 20 consecutive patients who underwent SDP with resection of the celiac axis between January 2005 and December 2018 were identified from a prospectively collected database and were matched with 20 patients experiencing SDP without resection of the celiac axis. Both perioperative parameters, as well as the overall postoperative course, were evaluated. RESULTS: The rate of perioperative complications in both groups was comparable (p=0.744). The rate of severe type C postoperative pancreatic haemorrhages (PPH) was significantly lower in patients with resection of the celiac axis compared to those without (p=0.035). CONCLUSION: The Appleby procedure may be considered as a safe and feasible treatment option with favorably fewer postoperative severe bleeding complications. Besides surgical expertise, such procedures, however, require an experienced interventional radiologist and should thus only be performed in high-volume centers.

RESUMO

BACKGROUND: Neoadjuvant chemotherapy (NAC) is established in the treatment of ductal pancreatic adenocarcinoma for downsizing borderline-resectable pancreatic cancer (BRPC) and may affect nodal positivity and rates of R0 resection. This study aimed to identify the impact of NAC on postoperative histopathological parameters with a prognostic relevance. PATIENTS AND METHODS: A one-to-three matched-pair analysis, including an overall total of 132 patients (25% treated with NAC and subsequent resection and 75% undergoing upfront surgery) was performed. Influence of NAC on nodal positivity, lymphatic, vascular and perineural invasion, as well as resection stage and grading, was examined. Furthermore, perioperative complications, in-hospital stay, re-admission rates, mortality, as well as preoperative body mass index and American Association of Anesthesiologist classification scores, were evaluated. RESULTS: Patients treated with NAC significantly less frequently had lymphatic tissue invasion (lymph node invasion: 51.5% vs. 72.7%; p=0.032, and lymphatic vessel invasion 9.4% vs. 55.3%; p=0.0004), whereas vascular and perineural invasion, as well as grading and resection state were not significantly different. Carbohydrate antigen 19-9 regression in correlation with nodal positivity also did not differ, and both groups showed comparable perioperative complication rates. Occurrence and severity of postoperative pancreatic fistula (18.2% vs. 24.3%; p=0.034) were significantly lower in patients who had undergone NAC. CONCLUSION: NAC significantly affects postoperative histopathological tumour stage in BRPC and appears to be a safe treatment option without increased perioperative complications, re-admission, in-hospital stay, or mortality. Further studies are mandatory to underline the suitability of NAC for ductal pancreatic adenocarcinoma subgroups in order to guide clinicians in their daily decision-making comprehensively.

RESUMO

BACKGROUND: Recent studies have suggested acute pancreatitis as a separate pancreatic-specific complication following pancreaticoduodenectomy. However, data on necrotizing pancreatitis of the pancreatic remnant is limited. This study aimed to evaluate parameters of patients undergoing completion pancreatectomy (CP) after initial pancreaticoduodenectomy (PD) and compare those with or without necrosis of the pancreatic remanent. METHODS: Patients who underwent CP following PD between January 2005 and December 2017 were identified from a prospectively collected database. Perioperative parameters were recorded, and patients were divided into those with or without histological evidence of necrosis of the pancreatic remnant. RESULTS: Postoperative acute necrotizing pancreatitis (POANP) was histologically detected in 33 (41%) of 79 patients after CP. Serum CRP levels on POD 2 and the day of revision were significantly higher in the POANP group (p < 0.001 for each). POANP was reflected by higher APACHE II and SOFA scores after PD (P < 0.001 for each). Although patients with POANP had an earlier revision, length of ICU and total hospital stay was prolonged (p < 0.001 for each). POANP was associated with more major complications (Clavien-Dindo ≥ 3) and more often necessitated reoperations within 30 days (p < 0.001 for each). CONCLUSION: Patients requiring CP following PD for POANP have an increased risk of major complications, and longer hospital stay. CRP levels, APACHE II and SOFA score, seem to correlate with the severity and might predict POANP. Universally accepted definitions with a clinically validated grading system of severity for POAP and POANP are needed to facilitate appropriate treatment strategies and enable comparison of future studies.
