    ABSTRACT: Objectives: The aim of this study was to determine the prevalence of pancreatic exocrine insufficiency in patients with pancreatic or periampullary cancer, both before and after resection. Methods: Systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines). We included studies reporting on pancreatic exocrine insufficiency in patients with pancreatic or periampullary cancer. Data on patient demographics, type of pancreatic resection, diagnostic test, and occurrence of pancreatic exocrine insufficiency were extracted. Prevalence of pancreatic exocrine insufficiency was calculated before and after pancreatic resections and in patients with locally advanced pancreatic cancer. Results: Nine observational cohort studies with 693 patients were included. Median preoperative prevalence of pancreatic exocrine insufficiency was 44% (range, 42%-47%) before pancreatoduodenectomy, 20% (range, 16%-67%) before distal pancreatectomy, 63% before total pancreatectomy, and 25% to 50% in patients with locally advanced pancreatic cancer. The median prevalence of pancreatic exocrine insufficiency at least 6 months after pancreatoduodenectomy was 74% (range, 36%-100%) and 67% to 80% after distal pancreatectomy. Conclusion: Pancreatic exocrine insufficiency is diagnosed in approximately half of all patients scheduled to undergo resection for pancreatic or periampullary cancer. The prevalence increases markedly after resection. These data highlight the need of pancreatic enzyme suppletion in these patients.

    ABSTRACT: Background: Surgery is the intervention of choice for definitive diagnosis and treatment in women with pathological nipple discharge (PND). Ductoscopy has been reported to improve diagnosis, but as an interventional procedure it may also reduce the need for surgery. This study evaluated interventional ductoscopy in patients with PND. Methods: A prospective study on ductoscopy was conducted in consecutive patients with PND, but without a suspected malignancy on routine diagnostic evaluation. Intraductal lesions were removed by ductoscopic extraction. Surgery was undertaken if there were suspicious ductoscopic findings or at the patient's request. Therapeutic efficacy was determined by cannulation success, detection and removal rates, symptom resolution and avoided surgery. Results: Ductoscope introduction was successful in 71 (87 per cent) of 82 patients, with abnormalities visualized in 53 (65 per cent); these were mostly polypoid lesions (29 patients). The lesion was removed in 27 of 34 attempted ductoscopic extractions. Twenty-six (32 per cent) of the 82 patients underwent surgery, whereas surgery was avoided in 56 (68 per cent). After a median follow-up of 17 (range 3-45) months, 40 patients (49 per cent) no longer experienced symptoms of PND, 13 of 34 patients experienced an insufficient therapeutic effect after attempted ductoscopic extraction, and the outcome was unknown in two (2 per cent). Malignancy was diagnosed in four patients (5 per cent); two had been missed at ductoscopy and two at initial surgery after ductoscopy. Conclusion: Interventional ductoscopy is technically feasible and may help to avoid surgery in the majority of patients. As endoscopic removal of intraductal lesions is not always possible and malignancy can be the underlying cause of PND, ductoscopic instruments should be further optimized to allow definitive histological diagnosis.

    ABSTRACT: Background: Traditionally, nonparasitic hepatic cysts are marsupialized using laparotomy. In the last 2 decades, laparoscopic fenestration has become the preferred treatment for hepatic cysts. However, this technique is limited by 2-dimensional view and the limited mobility of straight laparoscopic instruments. These limitations may be overcome by the use of a robotic system. We describe laparoscopic fenestration of giant hepatic cysts using the da Vinci Si robotic system with the use of the Endowrist One Vessel Sealer. Methods: Our first patient is a 32-year-old female with a solitary hepatic cyst. The second patient is a 51-year-old female with polycystic liver disease. Results: We performed robot-assisted laparoscopic cyst fenestration with good clinical outcome. No intraoperative complications occurred and patients recovered rapidly. Conclusion: These data show that the da Vinci Si robotic system is eminently suited for the laparoscopic fenestration of large hepatic cysts and that this procedure is associated with rapid recovery.

    ABSTRACT: Background: Active efflux of irinotecan by ATP-binding cassette (ABC)-transporters, in particular ABCB1 and ABCG2, is a well-established drug resistance mechanism in vitro and in pre-clinical mouse models, but its relevance in colorectal cancer (CRC) patients is unknown. Therefore, we assessed the association between ABC-transporter expression and tumour response to irinotecan in patients with metastatic CRC. Methods: Tissue microarrays of a large cohort of metastatic CRC patients treated with irinotecan in a prospective study (CAIRO study; n=566) were analysed for expression of ABCB1 and ABCG2 by immunohistochemistry. Kaplan-Meier and Cox proportional hazard regression analyses were performed to assess the association of ABC transporter expression with irinotecan response. Gene expression profiles of 17 paired tumours were used to assess the concordance of ABCB1/ABCG2 expression in primary CRC and corresponding metastases. Results: The response to irinotecan was not significantly different between primary tumours with positive versus negative expression of ABCB1 (5.8 vs 5.7 months, p=0.696) or ABCG2 (5.7 vs 6.1 months, p=0.811). Multivariate analysis showed neither ABCB1 nor ABCG2 were independent predictors for progression free survival. There was a mediocre to poor concordance between ABC-transporter expression in paired tumours. Conclusion: In metastatic CRC, ABC-transporter expression in the primary tumour does not predict irinotecan response.

    ABSTRACT: An association between ABO blood type and the development of cancer, in particular, pancreatic cancer, has been reported in the literature. An association between blood type O and neuroendocrine tumors in multiple endocrine neoplasia type 1 (MEN1) patients was recently suggested. Therefore, blood type O was proposed as an additional factor to personalize screening criteria for neuroendocrine tumors in MEN1 patients. The aim of this study was to assess the association between blood type O and the occurrence of neuroendocrine tumors in the national Dutch MEN1 cohort. Cohort study using the Dutch National MEN1 database, which includes >90% of the Dutch MEN1 population. Demographic and clinical data were analyzed by blood type. Chi-square tests and Fisher exact tests were used to determine the association between blood type O and occurrence of neuroendocrine tumors. A cumulative incidence analysis (Gray's test) was performed to assess the equality of cumulative incidence of neuroendocrine tumors in blood type groups, taking death as a competing risk into account. ABO blood type of 200 of 322 MEN1 patients was known. Demographic and clinical characteristics were similar amongst blood type O and non-O type cohorts. The occurrence of neuroendocrine tumors of the lung, thymus, pancreas and the gastrointestinal tract was equally distributed across the blood type O and non-O type cohorts (Grays's test for equality; P = 0.72). Furthermore, we found no association between blood type O and the occurrence of metastatic disease or survival. An association between blood type O and the occurrence of neuroendocrine tumors in MEN1 patients was not confirmed. Addition of the blood type to screening and surveillance practice seems for this reason not of additional value for identifying MEN1 patients at risk for the development of neuroendocrine tumors, metastatic disease or a shortened survival.

    ABSTRACT: Background Pancreatic fistula is a potentially life-threatening complication after a pancreatic resection. The aim of this systematic review was to evaluate the role of matrix-bound sealants after a pancreatic resection in terms of preventing or ameliorating the course of a post-operative pancreatic fistula.MethodsA systematic search was performed in the literature from May 2005 to April 2015. Included were clinical studies using matrix-bound sealants after a pancreatic resection, reporting a post-operative pancreatic fistula (POPF) according to the International Study Group on Pancreatic Fistula classification, in which grade B and C fistulae were considered clinically relevant.ResultsTwo were studies on patients undergoing pancreatoduodenectomy (sealants n = 67, controls n = 27) and four studies on a distal pancreatectomy (sealants n = 258, controls n = 178). After a pancreatoduodenectomy, 13% of patients treated with sealants versus 11% of patients without sealants developed a POPF (P = 0.76), of which 4% versus 4% were clinically relevant (P = 0.87). After a distal pancreatectomy, 42% of patients treated with sealants versus 52% of patients without sealants developed a POPF (P = 0.03). Of these, 9% versus 12% were clinically relevant (P = 0.19).Conclusions The present data do not support the routine use of matrix-bound sealants after a pancreatic resection, as there was no effect on clinically relevant POPF. Larger, well-designed studies are needed to determine the efficacy of sealants in preventing POPF after a pancreatoduodenectomy.

    ABSTRACT: Early oral feeding is currently considered the optimal routine feeding strategy after pancreatoduodenectomy (PD). Some have suggested that patients with preoperative symptoms of gastric outlet obstruction (GOO) who undergo PD have such a high risk of developing delayed gastric emptying that these patients should rather receive routine postoperative tube feeding. The aim of this study was to determine whether clinical outcomes after PD in these patients differ between postoperative early oral feeding and routine tube feeding. We analyzed a consecutive multicenter cohort of patients with preoperative symptoms of GOO undergoing PD (2010-2013). Patients were categorized into two groups based on the applied postoperative feeding strategy (dependent on their center's routine strategy): early oral feeding or routine nasojejunal tube feeding. Of 497 patients undergoing PD, 83 (17%) suffered from preoperative symptoms of GOO. 49 patients received early oral feeding and 29 patients received routine tube feeding. Time to resumption of adequate oral intake (primary outcome; 14 vs. 12 days, p = 0.61) did not differ between these two feeding strategies. Furthermore, overall complications and length of stay were similar in both groups. Of the patients receiving early oral feeding, 24 (49%) ultimately required postoperative tube feeding. In patients with an uncomplicated postoperative course, early oral feeding was associated with shorter time to adequate oral intake (8 vs. 12 days, p = 0.008) and shorter hospital stay (9 vs. 13 days, p < 0.001). Also in patients with preoperative symptoms of GOO, early oral feeding can be considered the routine feeding strategy after PD. Copyright © 2015 IAP and EPC. Published by Elsevier B.V.

    ABSTRACT: The aim of this study was to investigate whether younger age at surgery is associated with the increased incidence of postoperative complications after prophylactic thyroidectomy in pediatric patients with multiple endocrine neoplasia (MEN) 2.The shift toward earlier thyroidectomy has resulted in significantly less medullary thyroid carcinoma (MTC)-related morbidity and mortality. However, very young pediatric patients might have a higher morbidity rate compared with older patients. Hardly any literature exists on complications in the very young.A retrospective single-center analysis was performed on the outcomes of MEN2 patients undergoing a prophylactic total thyroidectomy at the age of 17 or younger. Forty-one MEN2A and 3 MEN2B patients with thyroidectomy after January 1993 and at least 6 months of follow-up were included, subdivided in 9 patients younger than 3 years, 15 patients 3 to 6 years, and 20 patients older than 6 years. Postoperative hypocalcemia and other complications were registered.Twelve (27%) patients developed transient hypocalcemia and 9 (20%) patients suffered from permanent hypocalcemia, with a nonsignificant trend toward higher incidence with decreasing age. Three (7%) patients had other complications, of whom 2 were younger than 3 years.For patients younger than 3 years, the average length of stay (LOS) was 6.7 days, versus 1.7 and 3.5 days, respectively, for the older patient groups (P < 0.05). Patients with complications had a longer LOS compared with patients without (5.0 vs 2.0, P < 0.01).None of the patients had clinical signs of recurrent MTC after a mean follow-up of 10.5 years.Prophylactic thyroidectomy in very young children is associated with a higher rate of complications, causing a significant increased LOS. Irrespective age of surgery, MTC did not recur in any patient. In planning optimal timing of surgery, clinicians should take the risk of complications into account. We advise not to perform total thyroidectomy before the age of 3 for patients defined high risk by the American Thyroid Association guideline.

    ABSTRACT: Since the 1950s, preoperative medical preparation has been widely applied in patients with pheochromocytoma to improve intraoperative hemodynamic instability and postoperative complications. However, advancements in preoperative imaging, laparoscopic surgical techniques, and anesthesia have considerably improved management in patients with pheochromocytoma. In consequence, there is no validated consensus on current predictive factors for postoperative morbidity. The aim of this study was to determine perioperative factors which are predictive for postoperative morbidity in patients undergoing laparoscopic adrenalectomy for pheochromocytoma. It is a retrospective analysis of prospectively maintained databases in five medical centers from 2002 to 2013. Inclusion criteria were consecutive patients who underwent non-converted laparoscopic unilateral total adrenalectomy for pheochromocytoma. Two-hundred and twenty-five patients were included. All-cause and cardiovascular postoperative morbidity rates were 16 % (n = 36) and 4.8 % (n = 11), respectively. Preinduction blood pressure normalization after preoperative medical preparation had no impact on postoperative morbidity. However, past medical history of coronary artery disease (OR [CI95 %] = 3.39; [1.317-8.727]) and incidence of intraoperative hemodynamic instability episodes (both SBP ≥ 160 mmHg and MAP < 60 mmHg) (OR [CI95 %] = 3.092; [1.451-6.587]) remained independent predictors for postoperative all-cause morbidity. Similarly, past medical history of coronary artery disease (OR [CI95 %] = 14.41; [3.119-66.57]), female sex (OR [CI95 %] = 12.05; [1.807-80.31]), and incidence of intraoperative hemodynamic instability episodes (both SBP ≥ 200 mmHg and MAP < 60 mmHg) (OR [CI95 %] = 4.13; [1.009-16.90]) remained independent predictors for postoperative cardiovascular morbidity. This study identifies risk factors for cardiovascular and all-cause postoperative morbidity after laparoscopic adrenalectomy in current clinical setting. These data can help physicians to guide intra-operative blood pressure management and have to be taken into account in further studies.

    ABSTRACT: Primary hyperparathyroidism is a common endocrine disorder for which the primary treatment is surgery. For minimal invasive parathyroidectomy adequate pre-operative imaging is essential. Conventional imaging is often inconclusive. There are reports that (18)F-fluorocholine PET-CT might be a superior imaging modality, however evidence is still very scarce. This is the first report of a case with negative ultrasound and sestamibi SPECT-CT imaging that underwent successful minimal invasive surgery because of (18)F-fluorocholine PET-CT. A 57 year-old man presented to us with complaints of fatigue. Laboratory results showed a biochemical primary hyperparathyroidism and an additional DEXA-scan revealed osteopenia of the lumbar spine. Conventional imaging consisting of neck ultrasound and Tc-99m-sestamibi SPECT-CT was however unable to localize the pathological gland. Subsequent (18)F-fluorocholine PET-CT did clearly localize an adenoma dorsally of the left thyroid lobe which was removed at that exact location using minimal invasive parathyroidectomy. Histological examination confirmed the diagnosis adenoma and calcium levels remained normal at follow-up. There is clinical need for a superior imaging modality to detect pathological parathyroid glands to enable minimal invasive surgery. (18)F-Fluorocholine is widely available. (18)F-Fluorocholine PET-CT is a promising new imaging modality for localizing parathyroid adenomas and enabling minimal invasive parathyroidectomy when conventional imaging fails to do. Clinicians should consider its use as a second line modality for optimal patient care. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    ABSTRACT: 18F-fluorocholine PET-CT is a new imaging modality for the localization of pathological parathyroid glands in patients with primary hyperparathyroidism. The PET-CT is a combination scan that uses both the physiological information from the PET and the anatomical information from the CT. Uptake of the radio-isotope 18F-fluorocholine is increased in pathological parathyroid glands. 18F-fluorocholine PET-CT helps clinicians to localize the pathological parathyroid glands where conventional modalities fail to do so. This enables surgeons to carry out targeted minimal invasive surgery. It may also prevent the patient having to undergo a more extensive exploration, with its associated risks, and alleviate the necessity of taking medications with side effects. Although the literature on this subject is still scarce, preliminary results are promising. As any hospital with a PET-CT can perform the scan, we expect that its use in patients with hyperparathyroidism will increase over the next few years.

    ABSTRACT: Open transthoracic esophagectomy is the worldwide gold standard in the treatment of resectable esophageal cancer. Robot-assisted minimally invasive thoraco-laparoscopic esophagectomy (RAMIE) for esophageal cancer may be associated with reduced blood loss, shorter intensive care unit (ICU) stay, and less cardiopulmonary morbidity; however, long-term oncologic results have not been reported to date. Between June 2007 and September 2011, a total of 108 patients with potentially resectable esophageal cancer underwent RAMIE at the University Medical Centre Utrecht, with curative intent. All data were recorded prospectively. Median duration of the surgical procedure was 381 min (range 264-636). Pulmonary complications were most common and were observed in 36 patients (33 %). Median ICU stay was 1 day, and median overall postoperative hospital stay was 16 days. In-hospital mortality was 5 %. The majority of patients (78 %) presented with T3 and T4 disease, and 68 % of patients had nodal-positive disease (cN1-3). In 65 % of patients, neoadjuvant treatment (chemotherapy 57 %, chemoradiotherapy 7 %, radiotherapy 1 %) was administered, and in 103 (95 %) patients, a radical resection (R0) was achieved. The median number of lymph nodes was 26, median follow-up was 58 months, 5-year overall survival was 42 %, median disease-free survival was 21 months, and median overall survival was 29 months. Tumor recurrence occurred in 51 patients and was locoregional only in 6 (6 %) patients, systemic only in 31 (30 %) patients, and combined in 14 (14 %) patients. RAMIE was shown to be oncologically effective, with a high percentage of R0 radical resections and adequate lymphadenectomy. RAMIE provided good local control with a low percentage of local recurrence at long-term follow up.

    ABSTRACT: Assessment of the diagnostic value of ultrasound (US), single photon-emission computed tomography-computed tomography (SPECT-CT) and (18)F-fluorocholine (FCH) PET-CT for preoperative localization of hyper-functioning parathyroid(s) in order to create a more efficient diagnostic pathway and enable minimal invasive parathyroidectomy (MIP) in patients with biochemical proven non-familial primary hyperparathyroidism (pHPT). A single-institution retrospective study of 63 consecutive patients with a biochemical diagnosis of non-familial pHPT who received a Tc-99m-sestamibi SPECT-CT and neck ultrasound. Surgical findings were used in calculating the sensitivity and the positive predictive value (PPV) of both imaging modalities. Furthermore we present 5 cases who received additional FCH PET-CT. A total of 42 (66.7%) patients underwent MIP. The PPV and sensitivity of SPECT-CT, 93.0% and 80.3%, were significantly higher than those of US with 78.3% and 63.2%, respectively. Adding US to SPECT-CT for initial pre-operative localization did not significantly increase sensitivity but did significantly decrease PPV. Performance of US was significantly better when performed after SPECT-CT. (18)F-fluorocholine PET-CT localized the hyper-functioning parathyroid gland in 4/5 cases with discordant conventional imaging, enabling MIP. SPECT-CT is the imaging modality of choice for initial pre-operative localization of hyper-functioning parathyroid gland(s) in patients with biochemical pHPT. Ultrasound should be performed after SPECT-CT for confirmation of positive SPECT-CT findings and for pre-operative marking allowing MIP. In cases with negative or discordant imaging additional FCH PET-CT should be considered since this might enable the surgeon to perform MIP. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    ABSTRACT: Colon tumors contain a fraction of undifferentiated stem cell-like cancer cells with high tumorigenic potential. Little is known about the signals that maintain these stem-like cells. We investigated whether differentiated tumor cells provide support. We established undifferentiated colonosphere cultures from human colon tumors and used them to generate stably differentiated cell lines. Antibody arrays were used to identify secreted factors. Expression of genes involved in stemness, differentiation, and the epithelial to mesenchymal (EMT) transition was measured using reverse transcription quantitative PCR. Expression of KIT in human tumors was analyzed with gene expression arrays and by immunohistochemistry. Colonospheres were injected into the livers of CBy.Cg-Foxn1nu/J mice. After liver tumors had formed hypoxia was induced by vascular clamping. Differentiated cells from various tumors, or medium conditioned by them, increased the clonogenic capacity of colonospheres. Stem cell factor (SCF) was secreted by differentiated tumor cells and supported the clonogenic capacity of KIT(+) colonosphere cells. Differentiated tumor cells induced the EMT in colonosperes; this was prevented by inhibition of KIT or SCF. SCF prevented loss of clonogenic potential under differentiation-inducing conditions. Suppression of SCF or KIT signaling greatly reduced the expression of genes that regulate stemness and the EMT and inhibited clonogenicity and tumor initiation. Bioinformatic and immunohistochemical analyses revealed a correlation between expression of KIT- and hypoxia-related genes in colon tumors, which was highest in relapse-prone mesenchymal-type tumors. Hypoxia induced expression of KIT in cultured cells and in human colon tumor xenografts and this contributed to the clonogenic capacity of the tumor cells. Paracrine signaling from SCF to KIT, between differentiated tumor cells and undifferentiated stem-like tumor cells, helps maintain the stem-like features of tumor cells, predominantly under conditions of hypoxia.

    ABSTRACT: Cardiac and pulmonary complications account for a large part of postoperative mortality, especially in the growing number of elderly patients. This review studies the effect of laparoscopic surgery for colorectal cancer on short term non-surgical morbidity. A literature search was conducted to identify randomised trials on laparoscopic compared to open surgery for colorectal cancer with reported cardiac or pulmonary complications. The search retrieved 3302 articles; 18 studies were included with a total of 6153 patients. Reported median or mean age varied from 56 years to 72 years. The percentage of included patients with ASA-scores ≥3 ranged from 7% to 38%. Morbidity was poorly defined. Overall reported incidence of postoperative cardiac complications was low for both laparoscopic and open colorectal resection (median 2%). There was a trend towards fewer cardiac complications following laparoscopic surgery (OR 0.66, 95% CI 0.41-1.06, p = 0.08), and this effect was most marked for laparoscopic colectomy (OR 0.28, 95% CI 0.11-0.71, p = 0.007). Incidence of pulmonary complications ranged from 0 to 11% and no benefit was found for laparoscopic surgery, although a possible trend was seen in favour of laparoscopic colectomy (OR 0.78, 95% CI 0.53-1.13, p = 0.19). Overall morbidity rates varied from 11% to 69% with a median of 33%. Although morbidity was poorly defined, for laparoscopic colectomies, significantly less cardiac complications occurred compared with open surgery and a trend towards less pulmonary complications was observed. Subgroup analysis from two RCTs suggests that elderly patients benefit most from a laparoscopic approach based on overall morbidity rates. Copyright © 2015 Elsevier Ltd. All rights reserved.
