RESUMO
BACKGROUND: Diabetes mellitus (DM) has a complex relationship with pancreatic cancer. This study examines the impact of preoperative DM, both recent-onset and pre-existing, on long-term outcomes following pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). METHODS: Data were extracted from the Recurrence After Whipple's (RAW) study, a multi-centre cohort of PD for pancreatic head malignancy (2012-2015). Recurrence and five-year survival rates of patients with DM were compared to those without, and subgroup analysis performed to compare patients with recent-onset DM (less than one year) to patients with established DM. RESULTS: Out of 758 patients included, 187 (24.7%) had DM, of whom, 47 of the 187 (25.1%) had recent-onset DM. There was no difference in the rate of postoperative pancreatic fistula (DM: 5.9% vs no DM 9.8%; p = 0.11), five-year survival (DM: 24.1% vs no DM: 22.9%; p = 0.77) or five-year recurrence (DM: 71.7% vs no DM: 67.4%; p = 0.32). There was also no difference between patients with recent-onset DM and patients with established DM in postoperative outcomes, recurrence, or survival. CONCLUSION: We found no difference in five-year recurrence and survival between diabetic patients and those without diabetes. Patients with pre-existing DM should be evaluated for PD on a comparable basis to non-diabetic patients.

BACKGROUND: Pancreatoduodenectomy (PD) is recommended in fit patients with a resectable ampullary adenocarcinoma (AA). We aimed to identify predictors of five-year recurrence/survival. METHODS: Data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD patients with a confirmed head of pancreas or periampullary malignancy (June 1st, 2012-May 31st, 2015). Patients with AA who developed recurrence/died within five-years were compared to those who did not. RESULTS: 394 patients were included and actual five-year survival was 54%. Recurrence affected 45% and the median time-to-recurrence was 14 months. Local only, local and distant, and distant only recurrence affected 34, 41 and 94 patients, respectively (site unknown: 7). Among those with recurrence, the most common sites were the liver (32%), local lymph nodes (14%) and lung/pleura (13%). Following multivariable tests, number of resected nodes, histological T stage > II, lymphatic invasion, perineural invasion (PNI), peripancreatic fat invasion (PPFI) and ≥1 positive resection margin correlated with increased recurrence and reduced survival. Furthermore, ≥1 positive margin, PPFI and PNI were all associated with reduced time-to-recurrence. CONCLUSIONS: This multicentre retrospective study of PD outcomes identified numerous histopathological predictors of AA recurrence. Patients with these high-risk features might benefit from adjuvant therapy.

Backgrounds/Aims: After pancreatoduodenectomy (PD), an early oral diet is recommended; however, the postoperative nutritional management of PD patients is known to be highly variable, with some centers still routinely providing parenteral nutrition (PN). Some patients who receive PN experience clinically significant complications, underscoring its judicious use. Using a large cohort, this study aimed to determine the proportion of PD patients who received postoperative nutritional support (NS), describe the nature of this support, and investigate whether receiving PN correlated with adverse perioperative outcomes. Methods: Data were extracted from the Recurrence After Whipple's study, a retrospective multicenter study of PD outcomes. Results: In total, 1,323 patients (89%) had data on their postoperative NS status available. Of these, 45% received postoperative NS, which was "enteral only," "parenteral only," and "enteral and parenteral" in 44%, 35%, and 21% of cases, respectively. Body mass index < 18.5 kg/m2 (p = 0.03), absence of preoperative biliary stenting (p = 0.009), and serum albumin < 36 g/L (p = 0.009) all correlated with receiving postoperative NS. Among those who did not develop a serious postoperative complication, i.e., those who had a relatively uneventful recovery, 20% received PN. Conclusions: A considerable number of patients who had an uneventful recovery received PN. PN is not without risk, and should be reserved for those who are unable to take an oral diet. PD patients should undergo pre- and postoperative assessment by nutrition professionals to ensure they are managed appropriately, and to optimize perioperative outcomes.
RESUMO
INTRODUCTION: Adjuvant chemotherapy (AC) can prolong overall survival (OS) after pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). However, fitness for AC may be influenced by postoperative recovery. We aimed to investigate if serious (Clavien-Dindo grade ≥ IIIa) postoperative complications affected AC rates, disease recurrence and OS. MATERIALS AND METHODS: Data were extracted from the Recurrence After Whipple's (RAW) study (n = 1484), a retrospective study of PD outcomes (29 centres from eight countries). Patients who died within 90-days of PD were excluded. The Kaplan-Meier method was used to compare OS in those receiving or not receiving AC, and those with and without serious postoperative complications. The groups were then compared using univariable and multivariable tests. RESULTS: Patients who commenced AC (vs no AC) had improved OS (median difference: (MD): 201 days), as did those who completed their planned course of AC (MD: 291 days, p < 0.0001). Those who commenced AC were younger (mean difference: 2.7 years, p = 0.0002), more often (preoperative) American Society of Anesthesiologists (ASA) grade I-II (74% vs 63%, p = 0.004) and had less often experienced a serious postoperative complication (10% vs 18%, p = 0.002). Patients who developed a serious postoperative complication were less often ASA grade I-II (52% vs 73%, p = 0.0004) and less often commenced AC (58% vs 74%, p = 0.002). CONCLUSION: In our multicentre study of PD outcomes, PDAC patients who received AC had improved OS, and those who experienced a serious postoperative complication commenced AC less frequently. Selected high-risk patients may benefit from targeted preoperative optimisation and/or neoadjuvant chemotherapy.

Backgrounds/Aims: Pancreatoduodenectomy (PD) is recommended in fit patients with a carcinoma (PDAC) of the pancreatic head, and a delayed resection may affect survival. This study aimed to correlate the time from staging to PD with long-term survival, and study the impact of preoperative investigations (if any) on the timing of surgery. Methods: Data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD outcomes. Only PDAC patients who underwent an upfront resection were included. Patients who received neoadjuvant chemo-/radiotherapy were excluded. Group A (PD within 28 days of most recent preoperative computed tomography [CT]) was compared to group B (> 28 days). Results: A total of 595 patents were included. Compared to group A (median CT-PD time: 12.5 days, interquartile range: 6-21), group B (49 days, 39-64.5) had similar one-year survival (73% vs. 75%, p = 0.6), five-year survival (23% vs. 21%, p = 0.6) and median time-todeath (17 vs. 18 months, p = 0.8). Staging laparoscopy (43 vs. 29.5 days, p = 0.009) and preoperative biliary stenting (39 vs. 20 days, p < 0.001) were associated with a delay to PD, but magnetic resonance imaging (32 vs. 32 days, p = 0.5), positron emission tomography (40 vs. 31 days, p > 0.99) and endoscopic ultrasonography (28 vs. 32 days, p > 0.99) were not. Conclusions: Although a treatment delay may give rise to patient anxiety, our findings would suggest this does not correlate with worse survival. A delay may be necessary to obtain further information and minimize the number of PD patients diagnosed with early disease recurrence.
RESUMO
BACKGROUND: Pancreatoduodenectomy (PD) is associated with significant postoperative morbidity. Surgeons should have a sound understanding of the potential complications for consenting and benchmarking purposes. Furthermore, preoperative identification of high-risk patients can guide patient selection and potentially allow for targeted prehabilitation and/or individualized treatment regimens. Using a large multicentre cohort, this study aimed to calculate the incidence of all PD complications and identify risk factors. METHOD: Data were extracted from the Recurrence After Whipple's (RAW) study, a retrospective cohort study of PD outcomes (29 centres from 8 countries, 2012-2015). The incidence and severity of all complications was recorded and potential risk factors for morbidity, major morbidity (Clavien-Dindo grade > IIIa), postoperative pancreatic fistula (POPF), post-pancreatectomy haemorrhage (PPH) and 90-day mortality were investigated. RESULTS: Among the 1348 included patients, overall morbidity, major morbidity, POPF, PPH and perioperative death affected 53 per cent (n = 720), 17 per cent (n = 228), 8 per cent (n = 108), 6 per cent (n = 84) and 4 per cent (n = 53), respectively. Following multivariable tests, a high BMI (P = 0.007), an ASA grade > II (P < 0.0001) and a classic Whipple approach (P = 0.005) were all associated with increased overall morbidity. In addition, ASA grade > II patients were at increased risk of major morbidity (P < 0.0001), and a raised BMI correlated with a greater risk of POPF (P = 0.001). CONCLUSION: In this multicentre study of PD outcomes, an ASA grade > II was a risk factor for major morbidity and a high BMI was a risk factor for POPF. Patients who are preoperatively identified to be high risk may benefit from targeted prehabilitation or individualized treatment regimens.

BACKGROUND: Improvements in bile duct injury repairs have been shown in centres with specialized surgeons. The aim of the present study was to demonstrate the temporal change in the pattern of referral, technical variation associated with repair and long-term outcome of bile duct injuries at a tertiary referral centre in Mexico City. METHODS: A retrospective case note review was performed. Patients were divided into two groups: group I (GI) 1990 to 2004 and group II (GII) 2005-2008, and appropriate statistical analysis undertaken. RESULTS: Over a 20-year period, 312 patients with iatrogenic bile duct injuries required surgical treatment (GI = 169, GII = 140 patients). All injuries were reconstructed using a Roux-en-Y hepaticojejunostomy. The proportion of patients who had undergone a laparoscopic cholecystectomy increased from 24% to 36% (P = 0.017) over the two time periods. In the second time period there was an increase in segment IV and V partial resections (P = 0.020), a reduction in the use of transanastomotic stents (42% to 2%, P = 0.001) and an increase in the proportion of patients requiring a neoconfluence (2% to 11%, P = 0.003). In the second time period, the number of patients requiring a hepatectomy during repair (2% to 1%, P = 0.001), a portoenterostomy (16% to 9%, P = 0.060) or a double-barrel hepatico-jejunostomy (5% to 1%, P = 0.045) significantly decreased. During follow-up, patients in the second time period had a reduction in the incidence of post-operative cholangitis (11% to 6%, P = 0.310) and the frequency of post-operative anastomotic stenoses (13% to 5%, P = 0.010). Mortality remained low throughout the series but was absent in the second group. CONCLUSIONS: Changes in technique and growing experience of the multidisciplinary team improved operative and long-term results of bile duct injury repair.

CONTEXT: High-intensity interval training (HIIT) has been widely used to prevent and treat cardiovascular risk factors in adolescents and adults; nevertheless, the available evidence in children is scarce. OBJECTIVE: To synthesize evidence regarding the effectiveness of HIIT interventions on improving cardiovascular risk factors and cardiorespiratory fitness (CRF) in children from 5 to 12 years old. DATA SOURCES: We searched 5 databases, Medline, Embase, SPORTDiscus, the Cochrane Library, and Web of Science. STUDY SELECTION: Randomized controlled trials (RCTs) evaluating the effectiveness of HIIT interventions on cardiometabolic risk factors and CRF in children were included. DATA EXTRACTION: Meta-analyses were conducted to determine the effect of HIIT on body composition, cardiometabolic and CRF variables in comparison with nontraining control groups. RESULTS: A total of 11 RCTs and 512 participants were included. The results of the meta-analysis revealed a significant improvement in peak oxygen uptake (standardized mean difference [SMD] = 0.70, 95% confidence interval [CI] = 0.28 to 1.12; P = 0.001], in total cholesterol [SMD = -1.09, 95% CI = -1.88 to -0.30; P = 0.007], in low-density lipoprotein cholesterol [SMD = -1.28, 95% CI = -2.34 to -0.23; P = 0.017] and triglycerides [SMD = -0.71, 95% CI = -1.15 to -0.28; P = 0.001) levels. LIMITATIONS: Because of the small number of available RCTs, it was not possible to conduct a subgroup analysis or a linear meta-regression analysis. CONCLUSIONS: HIIT is a feasible and time-efficient approach for improving CRF, total cholesterol, low-density lipoprotein cholesterol, and triglycerides levels in children.

BACKGROUND & AIMS: Mucin-producing neoplasms (MPNs) of the pancreas include mucinous cystic neoplasms (MCNs) and main-duct, branch-duct, and combined intraductal papillary mucinous neoplasms (IPMNs). MCNs and branch-duct IPMNs are frequently confused; it is unclear whether main-duct, combined, and branch-duct IPMNs are a different spectrum of the same disease. We evaluated their clinical and epidemiologic characteristics. METHODS: Patients who underwent resection for histologically confirmed MPNs were identified (N = 557); specimens were reviewed and eventually reclassified. RESULTS: One hundred sixty-eight patients (30%) had MCNs, 159 (28.5%) had branch-duct IPMNs, 149 (27%) had combined IPMNs, and 81 (14.5%) had main-duct IPMNs. Patients with MCNs were significantly younger and almost exclusively women; 44% of patients with main-duct or combined IPMNs and 57% of those with branch-duct IPMNs were women. MCNs were single lesions located in the distal pancreas (95%); 11% were invasive. IPMNs were more frequently found in the proximal pancreas; invasive cancer was found in 11%, 42%, and 48% of branch-duct, combined, and main-duct IPMNs, respectively (P = .001). Patients with invasive MCN and those with combined and main-duct IPMNs were older than those with noninvasive tumors. The 5-year disease-specific survival rate approached 100% for patients with noninvasive MPNs. The rates for those with invasive cancer were 58%, 56%, 51%, and 64% for invasive MCNs, branch-duct IPMNs, main-duct IPMNs, and combined IPMNs, respectively. CONCLUSIONS: MPNs comprise 3 different neoplasms: MCNs, branch-duct IPMNs, and main-duct IPMNs, including the combined type. These tumors have specific clinical, epidemiologic, and morphologic features that allow a reasonable degree of accuracy in preoperative diagnosis.

BACKGROUND: Bile duct injuries (BDI) have a wide array of presentation. Left partial injuries (Strasberg D) of the hepatic duct are the result of excessive traction, which dissects the hepatic hilum and provokes medial perforations without continuity loss. Right partial injuries (Strasberg A, B and C) are produced by direct damage to the hepatic duct or isolated injury to the right and accessory ducts. It is important to determine frequency, spectrum and treatment outcome of this BDI in the surgical scenario. METHODS: Patients with BDI who underwent surgical treatment in our hospital were reviewed, right and left partial injuries were selected. Demographic, clinical and therapeutic data were analyzed. RESULTS: In a 16-year period, 405 patients underwent surgical treatment of BDI. 31 (8%) were classified as a left partial injury (Strasberg D): 23 injuries at the common hepatic duct treated with a Hepatojejunostomy (HJ); four at the confluence level which received a HJ with neoconfluence construction; two partial injuries in the left hepatic duct underwent a selective left HJ; and two complete occlusions of the left hepatic duct, one treated with a partial hepatectomy and the last case underwent a partial HJ. Right partial injuries (Strasberg A, B or C) were identified in 21 cases (5%), their treatment was tailored according to the type of BDI (conservative, selective HJ, or hepatectomy). CONCLUSIONS: In our series the frequency of left and right partial BDI injuries was 8% and 5%, respectively. The spectrum of analyzed injuries included four subtypes for the left partial and eight for the right partial lesions. Most BDI in the two analyzed groups presented concomitant devascularization of the extra-hepatic ducts, therefore receiving surgical treatment rather than endoscopic treatment was done.

BACKGROUND: No previous systematic review has examined the effect of high-intensity interval training (HIIT) interventions on body composition, cardiometabolic risk factors and cardiorespiratory fitness (CRF) in healthy schoolchildren from 5 to 12 years old. METHODS: This study will be conducted by following the guideline of the preferred reporting items for systematic review and meta-analysis protocols. An electronic search in MEDLINE (via PubMed), EMBASE (via Scopus), SPORTDiscus, Cochrane Library and Web of Science databases of all dates from inception will be conducted. We will include randomized controlled trials aimed to assess the effectiveness of HIIT to improve cardiometabolic risk factors, body composition, and CRF in children. Two authors will perform the study selection and data collection; disagreements will be solved by a third reviewer. The methodological quality of studies will be assessed by the Cochrane Collaboration's tool for assessing risk of bias (RoB2). Data analysis and synthesis will be performed by Comprehensive Meta-analysis Software and StataSE software, version 15. CONCLUSION: The results should be disseminated through publication in a peer-reviewed journal. Since the data used in systematic reviews of this type will be extracted exclusively from published studies, approval form and ethics committee will not be required.

CONTEXT: Heterotopic pancreas is defined as ectopic pancreatic tissue without vascular or anatomic continuity with the normal pancreas. The spleen is a rare site of origin. This case report describes a patient with a malignant insulinoma which originated from an intrasplenic heterotopic pancreas. CASE REPORT: A 46-year-old man with three previous episodes of neuroglucopenic and adrenergic symptoms was referred to our hospital. A fasting test was performed and discontinued due to hypoglycemic symptoms. Preoperative studies failed to demonstrate any pancreatic lesions. However, a heterogeneous encapsulated tumor in the spleen was found on MRI. During surgery, only the splenic tumor was found, with neither vascular nor anatomical connections to the normal pancreas. Pathology reported a malignant insulinoma. Insulin and proinsulin were documented by immunohistochemistry. After one year of follow up, the patient is free of symptoms and no recurrent disease has been documented. DISCUSSION: Only seven cases of splenic heterotopic pancreas have been reported, six with cystic mucinous neoplasms. In addition, only one case of a malignant insulinoma arising from heterotopic pancreas has previously been described. This is the second case reported of an insulinoma arising from heterotopic pancreas and the first to originate from intrasplenic heterotopia.

BACKGROUND: Nodal metastasis is considered a major prognostic factor in patients with ampulla of Vater carcinoma (AVC). No study has investigated the significance of the ratio between metastatic and resected/examined lymph nodes (LNR) in patients with AVC. METHODS: Demographic, operative, and pathology data, including number of resected/evaluated nodes and LNR, were collected from patients who underwent pancreaticoduodenectomy with radical intent for invasive AVC from 1990 to 2005. Survival rates and recurrence patterns were evaluated and predictors were identified. RESULTS: In 90 evaluable patients (51 males, 39 females, median age 62.5 years), 5-year disease-specific survival (DSS) was 61%. The median number of resected/evaluated nodes was 16 (range: 5-47); 50% of the patients had nodal metastases. The 5-year DSS according to LNR was 75%, 49%, 38%, and 0% for LNR = 0, LNR >0 and < or =0.2, LNR >0.2, and < or =0.4, and LNR >0.4 (P = 0.002), respectively. The 5-year DSS was 81% in patients with >16 resected/evaluated nodes compared with 45% in those with < or =16 resected/evaluated nodes (P = 0.001). On multivariate analysis LNR and a number of resected/evaluated nodes >16 were significant predictors of survival; a number of resected/evaluated nodes >16 was also the only independent predictor of recurrence. CONCLUSIONS: After curative resection for AVC, LNR and a cutoff of 16 resected/evaluated nodes are powerful prognostic factors. LNR might represent a major parameter for patient stratification in adjuvant treatment trials.

In pancreatic cancer patients, survival and palliation of symptoms should be balanced with social and functional impairment, and for this reason, health-related quality of life measurements could play an important role in the decision-making process. The aim of this work was to evaluate the quality of life and survival in 92 patients with different stages of pancreatic adenocarcinoma who underwent surgical and/or medical interventions. Patients were evaluated with the Functional Assessment of Cancer Therapy questionnaires at diagnosis and follow-up (3 and 6 months). At diagnosis, 28 patients (30.5%) had localized disease (group 1) and underwent surgical resection, 34 (37%) had locally advanced (group 2), and 30 (32.5%) metastatic disease (Group 3). Improvement in quality of life was found in group 1, while in group 3, it decreased at follow-up (p=0.03). No changes in quality of life in group 2 were found. Chemotherapy/chemoradiation seems not to significantly modify quality of life in groups 2 and 3. Median survival time for the entire cohort was 9.8 months (range, 1-24). One-year survival was 74%, 30%, and 16% for groups 1, 2, and 3 respectively (p=0.001). Pancreatic cancer prognosis is still dismal. In addition to long-term survival benefits, surgery impacts favorably quality of life.

There are few reports of intrapancreatic accessory spleen. Most cases have been reported in Japan and some refer epithelial cysts within it. Most of these lesions are asymptomatic and may be misdiagnosed as a non-functioning neuroendocrine tumor due to their radiological characteristics and lack of symptomatology. We report a case of a 46 year old woman with an incidentally diagnosed intrapancreatic accessory spleen. Because of a history of weight loss and a severe acanthosis nigricans a hidden neoplasia was sought. A 2.5 x 1 cm lesion was found in the tail of the pancreas on computed tomography scan and later confirmed with endoscopic ultrasound. A non-diagnostic biopsy was undertaken. A distal pancreatectomy with splenectomy was performed and a final pathological diagnosis of intrapancreatic accessory spleen was given. The 99mTc-denatured RBC scan in addition to the octreotide scintigraphy have been proposed to differentiate it from other intrapancreatic tumors and avoid unnecessary surgery. Intrapancreatic accessory spleen should be considered as a differential diagnosis for pancreatic tumors.

Roux-en-Y hepatojejunostomy is the procedure of choice for biliary reconstruction after complex iatrogenic injury that is usually associated with vascular injuries and concomitant ischemia of the ducts. To avoid the ischemic component, our group routinely performs a high repair to assure an anastomosis in noninflamed, nonscarred, and nonischemic ducts. If the duct bifurcation is preserved, the Hepp-Couinaud approach for reconstruction is an excellent choice. Partial liver resection of segments IV and V allows adequate exposure of the bile duct at its bifurcation with an anterior approach of the ducts (therefore not jeopardizing the circulation), allowing a high quality anastomosis. Long-term results of bile duct reconstruction using this approach are described. Two hundred eighty-five bile duct reconstructions were done between 1989 and 2004 in a tertiary care university hospital. The first partial-segment IV resection was done in 1994; 94 cases have been reconstructed since then using this approach. All of them had a complex injury (Strasberg E1-E5), and although in many cases the bifurcation was preserved (E1-E3), a high bilioenteric anastomosis was done to facilitate the reconstruction. In 70 cases, the bifurcation was identified, and in the 24 in which the confluence was not preserved, the right and left ducts were found except in one case. In three patients, the right duct was found unsuitable for anastomosis, and a liver resection was done. In the remaining 21, an anastomosis was done using a stent (transhepatic, transanastomotic) through the right duct. According to Lillemoe's criteria, 86 cases had good results (91%). In four of the eight remaining patients, there was the need to operate again due to the presence of an obstruction and/or cholangitis. In the rest, radiological instrumentation was done. Four of these cases have developed secondary biliary cirrhosis, two of which have died while waiting for a liver transplant, four and six years after reconstruction. Partial segments IV and V resection allows adequate exposure of the confluence and the isolated left or right hepatic ducts. Anterior exposure of the ducts allows an anastomosis in well-preserved, nonischemic, nonscarred, or noninflamed ducts. Parenchyma removal also allows the free placement of the jejunal limb, without external compression and tension, obtaining a high quality anastomosis with excellent long-term results.

INTRODUCTION: T tubes can be placed in the bile ducts either open or laparoscopically for several reasons such as: extraction of stones, biliary reconstruction after liver transplant and in end-to-end anastomosis in iatrogenic injuries. Inadequate placement of the T tube, long term stay and technical difficulties that can affect the outcome, can lead to an injury that usually requires a biliodigestive reconstruction. METHODS: In a 15-year period (1990-2005) a total of 343 patients have been referred to our university hospital for biliary reconstruction. Files of those patients in which the injury was due to misplacement of a T tube or associated with a long-term stay were reviewed. We evaluated the type of injury, technique used for the reconstruction, longterm staying of the T tubes (1-6 months), hospital in stay, long term outcomes as well as associated comorbidities. RESULTS: In 42 cases a biliary injury related to a T tube was identified (13%). All the injuries were classified as Strasberg E, with demonstration of a fistula (internal or external); 18 to the duodenum, 5 to the jejunum-ileum and 3 to the colon. A hepatojejunostomy was done to all patients; the duodenum and small gut fistulas were closed and in the 3 cases with colonic injury a right hemicolectomy was performed. The postoperative evolution was adequate without major complications but with a longer hospital stay. In 39 of the 42 patients (92%), good postoperative results were obtained. Only one case required a new surgery (22 months after the first one), due to recidivant cholangitis. CONCLUSION: Inadequate placement of the T tubes and long-term stay can produce complex biliary injuries with associated comorbidities such as fistulas to the adjacent viscera. Placement of T tubes need a careful surgical technique and their indication must be carefully assessed.

Roux en Y hepatojejunostomy is the surgery of choice for bile duct repair. Anastomotical dysfunction after reconstruction has several etiopathologies. Besides technical factors, ischemia of the duct is responsible for late obstruction. Bile colonization with secondary stones and sludge can also be identified as a cause. An unusual cause of anastomotical dysfunction secondary to ascaris biliary infestation after biliary reconstruction is reported herein. The patient had intermittent cholangitis and eosinophilia. At operation, the worm was found obstructing the anastomosis.

INTRODUCTION: Few studies compare the direct impact of pancreatoduodenectomy (PD) on the patient's quality of life (QOL). The effect of PD in QOL, comparing the preoperative vs. postoperative status, was analyzed. METHOD: A prospective single-center study was performed. PD patients in a 2-year period were included. A general QOL instrument was applied preoperative, 1, 3, 6, and 12 months after surgery and compared with national norms. RESULTS: Thirty-seven patients were recruited. Twenty of 37 were female. Ampullary carcinoma 14/37, ductal adenocarcinoma in 9/37, and other malignant neoplasms 14/37 were diagnosed. Mortality was absent; 48.6% had complications, 13.5 % required reoperation. Three (median) and 4 (mode) questionnaires were answered per individual. 85 % answered the last questionnaire. 4/37 had cancer related death before a year. Median follow-up was 29 (3-72) months. QOL diminished a month after surgery, physical function (67 vs 40, p<0.0001) and emotional role (37 vs 17, p<0.032) did so significantly. Three months after surgery QOL improved yet not significantly. Six and 12 months postoperatively, physical role (9 vs 49, p=0.001), physical pain (51 vs 71, p=0.01), social function (52 vs 63, p=0.014), vitality (54 vs 64, p=0.018), and emotional role (41 vs 69, p=0.006) improved significantly. DISCUSSION: PD has a favorable impact in quality of life as demonstrated by the improvement of most parameters assessed in the postoperative period.
