Enhanced Recovery After Pancreatic Surgery Does One Size Really Fit All? A Clinical Score to Predict the Failure of an Enhanced Recovery Protocol After Pancreaticoduodenectomy.

BACKGROUND: The inability to comply with enhanced recovery protocols (ERp) after pancreaticoduodenectomy (PD) is a real but understated issue. Our goal is to report our experience and a potential tool to predict ERp failure in order to better characterize this problem. METHODS: From January 1, 2014, to January 31, 2016, 205 consecutive patients underwent PD in our center and were managed according to an ERp. Failure to comply with postoperative protocol items was defined as any of: no active ambulation on postoperative day 1 (POD1); less than 4 h out of bed on POD2; removal of nasogastric tube and bladder catheter after POD1 and POD3, respectively; reintroduction of oral feeding after POD4; and continuation of intravenous infusions after POD4. Data were collected in a prospective database. RESULTS: Taking in consideration the number of failed items and the length of stay, we defined failure of the ERp as no compliance to two or more items. A total of 116 patients (56.6%) met this definition of failure. We created a predictive model consisting of age, BMI, operative time, and pancreatic stump consistency. These variables were independent predictors of failure (OR 1.03 [1.001-1.06] p = 0.01; OR 1.11 [1.01-1.22] p = 0.03; OR 1.004 [1.001-1.009] p = 0.02 and OR 2.89 [1.48-5.67] p = 0.002, respectively). Patient final score predicted the failure of the ERp with an area under the ROC curve of 0.747. CONCLUSIONS: It seems to be possible to predict ERp failure after PD. Patients at high risk of failure may benefit more from a specific ERp.

Thrombosis of the dorsal vein of the penis as first clinical presentation of pancreatic cancer metastatic to the penis.

INTRODUCTION: Though metastatic disease is a common presentation of pancreatic adenocarcinoma, localization to the penis is an extremely rare event despite its abundant vascularization. Primary cancers responsible for penile metastases usually occur in prostate and rectum and are often associated with disseminated malignancy and poor prognosis. CASE DESCRIPTION: A 66-year-old man was diagnosed with adenocarcinoma of the tail of the pancreas after the onset of thrombosis of the dorsal vein of the penis; pubis ultrasound and total body computed tomography scan were negative for metastases at other sites. The patient was submitted to distal pancreatectomy with splenectomy for a pT3 N1 G4 pancreatic ductal adenocarcinoma. Three weeks after discharge, the patient returned to the outpatient clinic complaining of a painful permanent turgidity of the penis shaft. Ultrasound revealed a complete replacement of the cavernosal bodies by multiple nodular masses and a penile biopsy confirmed metastases from the primary pancreatic cancer. The patient started chemotherapy with NAB-paclitaxel and gemcitabine, with excellent control of symptoms. However, the disease progressed to bone and liver and the patient died 9 months after surgery. CONCLUSIONS: Penile localization is an extremely rare event and a standard of care has not been elaborated. Treatments are palliative and mainly aimed at pain relief and can comprise chemotherapy, radiotherapy, and surgery. Identification of venous thrombosis as an early sign of involvement could potentially offer patients an earlier diagnosis and a better treatment option.

Parenchyma-sparing surgery for pancreatic endocrine tumors.

Enucleation (EN) and middle pancreatectomy (MP) have been proposed as a treatment for G1 and G2 pancreatic neuroendocrine tumors (PNET). The aim of this study is to analyze the outcomes of parenchyma-sparing surgery (PSS) for PNET in an Italian high-volume center. All patients with a histological diagnosis of PNET who underwent surgical resection in our center between January 2010 and January 2016 were included in the study. Demographic, perioperative, and discharge data were collected in a prospective database. Follow-up was considered until March 31, 2016. 99 patients were included. PSS was performed in 22 cases (22.2 %), 18 EN (82 %), and 4 MP (18 %). 89.8 % patients were staged with CT scan, 69.6 % with endoscopic ultrasonography, 48.4 % with MRI, and 47.4 % with 68Ga-PET. Pre-operative histological diagnosis was obtained in 68.6 %. Most of PSS tumors were G1 (n = 15; 68 %) and there were no G3. Nodal sampling was performed in every PSS. Only two patients showed nodal metastatic disease. The median post-operative length of stay was 7 days after PSS. Eleven (50 %) of these patients developed a complication; two (18.2 %) were major complications. Pancreatic fistula developed in ten patients (45.5 %); two (20 %) were type B. There were no type C fistula and no re-operations after PSS. Readmission rate was 9 %. All patients submitted to PSS are alive and free of recurrence. PSS is a safe technique for G1 and G2 PNETs, but it has to be conducted in experienced centers and an extensive nodal sampling and a long follow-up are required for the best oncologic outcome.

Morphohistological features of pancreatic stump are the main determinant of pancreatic fistula after pancreatoduodenectomy.

INTRODUCTION: Pancreatic surgery is challenging and associated with high morbidity, mainly represented by postoperative pancreatic fistula (POPF) and its further consequences. Identification of risk factors for POPF is essential for proper postoperative management. AIM OF THE STUDY: Evaluation of the role of morphological and histological features of pancreatic stump, other than main pancreatic duct diameter and glandular texture, in POPF occurrence after pancreaticoduodenectomy. PATIENTS AND METHODS: Between March 2011 and April 2013, we performed 145 consecutive pancreaticoduodenectomies. We intraoperatively recorded morphological features of pancreatic stump and collected data about postoperative morbidity. Our dedicated pathologist designed a score to quantify fibrosis and inflammation of pancreatic tissue. RESULTS: Overall morbidity was 59,3%. Mortality was 4,1%. POPF rate was 28,3%, while clinically significant POPF were 15,8%. Male sex (P = 0.009), BMI ≥ 25 (P = 0.002), prolonged surgery (P = 0.001), soft pancreatic texture (P < 0.001), small pancreatic duct (P < 0.001), pancreatic duct decentralization on stump anteroposterior axis, especially if close to the posterior margin (P = 0.031), large stump area (P = 0.001), and extended stump mobilization (P = 0.001) were related to higher POPF rate. Our fibrosis-and-inflammation score is strongly associated with POPF (P = 0.001). DISCUSSION AND CONCLUSIONS: Pancreatic stump features evaluation, including histology, can help the surgeon in fitting postoperative management to patient individual risk after pancreaticoduodenectomy.
