Impact of Surgical Modalities on Long-term Survival Outcomes of Patients with Duodenal Gastrointestinal Stromal Tumor.

BACKGROUND: The optimal surgical modality for duodenal gastrointestinal stromal tumor (GIST) remains undefined. The purpose of this study was to evaluate long-term survival outcomes of patients who underwent radical resection (RR) or limited resection (LR) of duodenal GIST. METHODS: A total of 325 patients identified from the Surveillance, Epidemiology and End Results (SEER) database who underwent surgery for duodenal GIST between 1986 and 2016 were classified into a LR group and a RR group based on the type of surgery received. Propensity score matching (PSM) was performed to minimize the selection bias in comparisons. Disease-specific survival (DSS) and overall survival (OS) were observed, and factors affecting the survival outcome were analyzed. RESULTS: In the entire cohort, 105 patients (32.3%) underwent RR and 220 (67.7%) received LR. Both the 5-year OS and DSS in RR group were significantly better than those in LR group (71.0% vs. 54.1%, P = 0.014; 66.6% vs. 49.1%, P = 0.025). PSM resulted in 95 pairs of patients, with long-term outcomes being comparable between the two groups. After adjusting covariates in the propensity matched cohort, the type of surgery still showed no significant impact on OS (hazard ratio [HR] 1.160; 95% confidence interval [CI] 0.662-2.033) and DSS (HR 1.208; 95% CI 0.686-2.128). CONCLUSIONS: Surgical modalities do not seem to have a significant impact on long-term survival outcomes of patients with duodenal GIST and should mainly depend on the tumor size and location.

Proposal of a new T-stage classification system for ampullary carcinoma based on Surveillance, Epidemiology and End Result (SEER) database.

BACKGROUND: Tumor size is still considered a useful prognostic factor in currently available tumor-node-metastasis (TNM) classification staging systems for most solid tumors, but the significance of tumor size on the prognosis of ampullary carcinoma remains controversial. The aim of the current study was to propose a new T-stage classification system for ampullary carcinoma to address the impact of tumor size on the prognostic outcome. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified 1080 patients with ampullary carcinoma who underwent radical surgical resection between 2004 and 2015. Based on the results obtained from analysis of various clinicopathologic factors, a new T-stage classification system was proposed. RESULTS: Among the 1080 patients, 618 were men and 462 were women, with a median tumor size of 2.3 (range 0.1-12) cm. Using the 7th edition of the American Joint Committee on Cancer (AJCC) staging manual, we noticed significant differences in overall survival (OS) between T2 vs. T3 tumors (P < 0.001) and T3 vs. T4 tumors (P = 0.002), but failed to observe significant differences between T1 vs. T2 tumors (P = 0.498) in our pair-wise comparison. Using the newly developed T-stage classification system, we were able to differentiate significant differences in OS between T1 vs. T2 tumors (P = 0.032), T2 vs. T3 tumors (P < 0.001) and T3 vs. T4 tumor (P = 0.003) in all pair-wise comparisons. The c-index of the new staging system was 0.653 (95% CI: 0.629-0.677), showing a better discriminatory power than the 0.636 of the 7th AJCC staging system (95% CI: 0.612-0.660). CONCLUSIONS: The new T-stage classification system described herein can better differentiate prognostic outcomes after radical resection in patients with ampullary carcinoma by incorporating tumor size and depth of tumor infiltration.

Physicians' End of Life Discussions with Patients: Is There an Ethical Obligation to Discuss Aid in Dying?

Since Oregon implemented its Death with Dignity Act, many additional states have followed suit demonstrating a growing understanding and acceptance of aid in dying (AID) processes. Traditionally, the patient has been the one to request and seek this option out. However, as Death with Dignity acts continue to expand, it will impact the role of physicians and bring up questions over whether physicians have the ethical obligation to facilitate a conversation about AID with patients during end of life discussions. Patients have the right to make informed decisions about their health, which implies that physicians have an obligation to discuss with and inform patients of the options that will accomplish the patients' goals of care. We will argue that physicians have an ethical obligation to inform certain patients about AID (in qualifying states) during end of life care discussions. We will also address what this obligation encompasses and explore guidelines of when and how these conversations should occur and proceed. Earlier guidelines, presented by various palliative care and ethics experts, for proceeding with such conversations have mostly agreed that the discussion of hospice and end of life care with patients should be initiated early and that the individual goals of a patient during the remaining duration of life should be thoroughly examined before discussion of appropriate options. In discussing AID, physicians should never recommend but inform patients about the basics so that they can make an informed decision. If patients express further interest in AID, the physician should open up the dialogue to address the reasoning behind this decision versus other possible treatments to ensure that patients clearly comprehend the process and implications of their decision. Ultimately, any end of life choice should be made by patients with the full capacity to express what they envision for the remaining duration of life and to comprehend the advantages and disadvantages of all the possible options.

The Prognostic Value of a Pathologic Complete Response After Neoadjuvant Therapy for Digestive Cancer: Systematic Review and Meta-Analysis of 21 Studies.

BACKGROUND: Neoadjuvant therapy (NAT) before radical excision has become the preferred initial option for locally advanced digestive cancers such as esophageal cancer (EC), esophagogastric junction adenocarcinoma (EGJAC), gastric adenocarcinoma (GAC), rectal cancer (RC), and pancreatic cancer (PC). Although some patients reportedly achieve a pathologic complete response (pCR) after neoadjuvant therapy, the published data are inconsistent regarding whether pCR yields a survival benefit. The current meta-analysis was performed to assess the potential prognostic value of pCR after preoperative therapy for patients with digestive cancers. METHODS: An extensive electronic search in PubMed, Web of Science, and the Cochrane Library was performed for relevant articles, from which data relative to independent correlations of pCR with overall survival (OS) and disease-free survival (DFS) were extracted for analysis. A random-effects model was used to calculate the pooled hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs). RESULTS: The study identified 6780 patients who met the inclusion and exclusion criteria. The results showed that pCR was significantly correlated with better OS (HR, 0.50; 95% CI, 0.43-0.58; P < 0.001) and DFS (HR, 0.49; 95% CI, 0.40-0.60; P < 0.001) for the digestive cancer patients who achieved pCR than for those who did not achieve pCR. Subgroup analysis showed that the correlation of pCR with OS was significant in EC (HR, 0.57; 95% CI, 0.47-0.69; P < 0.001), EGJAC/GAC (HR, 0.38; 95% CI, 0.17-0.86; P = 0.02), RC (HR, 0.48; 95% CI, 0.28-0.81; P = 0.006), and PC (HR, 0.41; 95% CI, 0.17-0.97; P = 0.04). In addition, the survival benefit for pCR patients was of similar magnitude, irrespective of the type of study, type of NAT, or ethnicity. CONCLUSIONS: A pCR is correlated with favorable survival outcomes compared with a non-pCR for digestive cancer patients after NAT.

Investigation of Listeriosis-Related Knowledge, Attitudes, and Practices Among Medical Staff in Fangshan, Beijing, China.

The aim of this study was to gain insight into the knowledge of, attitude toward, and practical experience with listeriosis among medical staff. In two hospitals in Fangshan, Beijing, 410 medical staff members were randomly selected using a random sampling method. Each selected staff member was invited to participate in a standardized questionnaire interview. In total, 397 valid questionnaires were collected. With regard to the staff members' general knowledge of listeriosis, they answered 65.96% of the items correctly. The knowledge scores among obstetricians and gynecologists were higher than those of other clinical doctors (p < 0.05); however, obstetricians and gynecologists were less knowledgeable about which drugs are effective against listeriosis than the other doctors (p = 0.007). The percentage of participants with a positive attitude about preventing listeriosis was 96.47%, the percentage with practice formation was 52.39%. The medical staff's mean score for knowledge of listeriosis was 4.61 ± 1.83. The mean score for attitude toward listeriosis was 9.71 ± 1.31. There was a significant association between attitude and knowledge of listeriosis (r = 0.221, p < 0.001). Medical staff obtained a mean score of 2.10 ± 1.07 for the practice formation. There was a significant association between practice formation and knowledge of listeriosis (r = 0.502, p < 0.001). The mean knowledge-attitude-practice (KAP) score for listeriosis among medical staff was 16.41 ± 3.19. The KAP scores were significantly correlated with age (r = 0.129, p = 0.011), occupation (r = -0.103, p = 0.041), department (r = -0.168, p = 0.001), and professional title (r = 0.166, p = 0.001). To improve medical outcomes and foodborne disease surveillance, medical staff should receive more training on listeriosis and the content of the training should be adjusted.

Long-term outcomes of combined hepatocellular-cholangiocarcinoma after hepatectomy or liver transplantation: A systematic review and meta-analysis.

BACKGROUND: Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare primary liver malignancy. We conducted a systematic review and meta-analysis to assess the evidence available on the long-term outcomes of cHCC-CC patients after either hepatectomy or liver transplantation (LT). DATA SOURCES: Relevant studies published between January 2000 and January 2018 were identified by searching PubMed and Embase and reviewed systematically. Data were pooled using a random-effects model. RESULTS: A total of 42 observational studies involving 1691 patients (1390 for partial hepatectomy and 301 for LT) were included in the analysis. The median tumor recurrence and 5-year overall survival (OS) rates were 65% (range 38%-100%) and 29% (range 0-63%) after hepatectomy versus 54% (range 14%-93%) and 41% (range 16%-73%) after LT, respectively. Meta-analysis found no significant difference in OS and tumor recurrence between LT and hepatectomy groups. CONCLUSION: Hepatectomy rather than LT should be considered as the prior treatment option for cHCC-CC.

Survival after repeat hepatectomy for recurrent colorectal liver metastasis: A review and meta-analysis of prognostic factors.

BACKGROUND: Frequent recurrent hepatic metastasis after hepatic metastasectomy is a major obstacle in the treatment of colorectal liver metastasis (CRLM). We performed the present systematic review to evaluate the short- and long-term outcomes after repeat hepatectomy for recurrent CRLM and determine factors associated with survival in these patients. DATA SOURCES: An electronic search of PubMed database was undertaken to identify all relevant peer-reviewed papers published in English between January 2000 and July 2018. Hazard ratios (HR) with 95% confidence interval (95% CI) were calculated for prognostic factors of overall survival (OS). RESULTS: The search yielded 34 studies comprising 3039 patients, with a median overall morbidity of 23% (range 8%-71%), mortality of 0 (range 0-6%), and 5-year OS of 42% (range 17%-73%). Pooled analysis showed that primary T3/T4 stage tumor (HR = 1.94; 95% CI: 1.04-3.63), multiple tumors (HR = 1.49; 95% CI: 1.10-2.01), largest liver lesion ≥5 cm (HR = 1.89; 95% CI: 1.11-3.23) and positive surgical margin (HR = 1.80; 95% CI: 1.09-2.97) at initial hepatectomy, and high serum level of carcinoembryonic antigen (HR = 1.87; 95% CI: 1.27-2.74), disease-free interval ≤12 months (HR = 1.34; 95% CI: 1.10-1.62), multiple tumors (HR = 1.64; 95% CI: 1.32-2.02), largest liver lesion ≥5 cm (HR = 1.85; 95% CI: 1.34-2.56), positive surgical margin (HR = 2.25; 95% CI: 1.39-3.65), presence of bilobar disease (HR = 1.62; 95% CI: 1.19-2.20), and extrahepatic metastases (HR = 1.60; 95% CI: 1.23-2.09) at repeat hepatectomy were significantly associated with poor OS. CONCLUSIONS: Repeat hepatectomy is a safe and effective therapy for recurrent CRLM. Long-term outcome is predicted mainly by factors related to repeat hepatectomy.

Synthesis and Electrochemical Properties of Yb3+-Doped Li1.20Mn0.54Ni0.13Co0.13O2 Cathode Materials Obtained by Sol-Gel Method.

The Li1.20[Mn0.54Ni0.13Co0.13]0.80-xYbxO2 (x = 0, 0.01, 0.02, 0.03) cathode materials have been synthesized by using sol-gel method and characterized by means of XRD, SEM, ICP-OES analysis. The galvanostatic charge-discharge tests results showed the improved electrochemical properties were obtained through the Yb3+ doping modification. With the increase of Yb3+ doping content, the capacity retentions enhanced from 85.6% to 88.9% and then decrease to 86.5% after 100 cycles with x = 0.01, 0.02 and 0.03, respectively, while the un-doped sample delivered the capacity retention of 83.0%. Besides, the discharge capacity of Li1.20 [Mn0.54Ni0.13Co0.13]0.78Yb0.02O2 was about 23.1 mAh g-1 larger than that of un-doped sample at 5C high rate. The electrochemical impedance spectroscopy (EIS) and cyclic voltammetric results indicated that the Yb3+ doping modification could suppress the layered-spinel phase transformation during cycling and maintain a lower value of charge transfer impedance.

A pooled analysis of treatment and prognosis of hepatic angiosarcoma in adults.

BACKGROUND: Hepatic angiosarcoma is a rare malignant vascular tumor presenting unique treatment challenges. The aim of the present study was to determine the treatment and prognosis of this entity. DATA SOURCES: A systematic literature search was conducted using PubMed, Embase and Chinese Biomedical Literature database, to identify articles published from January 1980 to July 2017. Search terms were "hepatic angiosarcoma" and "liver angiosarcoma". Additional articles were retrieved through manual search of bibliographies of the relevant articles. Pooled individual data concerning the prognosis following various therapeutic modalities were analyzed. RESULTS: A total of 75 articles involving 186 patients were eligible for inclusion. The median overall survival (OS) was 8 months, with 1-, 3-, and 5-year OS rates of 36.6%, 22.3%, and 12.0%, respectively. The median OS after partial hepatectomy (n = 86), chemotherapy (n = 36), liver transplantation (n = 17), and supportive care (n = 46) were 15, 10, 5 and 1.3 months, respectively. Small tumor size (<10 cm) was the only significant favorable factor for OS after partial hepatectomy (P = 0.012). CONCLUSIONS: Despite the dismal prognosis, partial hepatectomy could prolong the survival of hepatic angiosarcoma patients, particularly those with tumors <10 cm. Chemotherapy could be an option for unresectable disease. Liver transplantation is not a recommendable option for the management of this malignancy.

An evidence-based approach to the surgical interventions for severe pancreatic fistula after pancreatoduodenectomy.

BACKGROUND AND OBJECTIVE: To assess the safety and therapeutic outcome of different surgical interventions for severe pancreatic fistula after pancreatoduodenectomy. METHODS: A systematic literature search was performed in PubMed database for relevant articles published between 1990 and March 2017. Descriptive statistics were performed and data are expressed as mean. RESULTS: Twenty-four studies involving 370 patients undergoing surgical interventions for severe pancreatic fistula after pancreatoduodenectomy were included. Rates of further relaparotomy, in-hospital mortality, and long-term endocrine insufficiency were reported for completion pancreatectomy (31.8%, 42% and 100% respectively), disconnection of anastomosis with preservation of a pancreatic remnant (25%, 21.3% and 17.8% respectively), internal or external wirsungostomy (10.4%, 14.9%, and 12.3% respectively), salvage pancreaticogastrostomy (12.5%, 0% and 25%, respectively), and simple peripancreatic drainage (30%, 47.9% and 12.5%, respectively). CONCLUSIONS: The pancreas-preserving strategy of disconnection of anastomosis with preservation of a pancreatic remnant, internal or external wirsungostomy, and salvage pancreatogastrostomy seems to be the preferred option for the treatment of severe pancreatic fistula after pancreatoduodenectomy. As completion pancreatectomy is a very aggressive treatment, it should only be reserved for specific instances in which organ-preserving resection is technically unfeasible.

Influence of cirrhosis on long-term prognosis after surgery in patients with combined hepatocellular-cholangiocarcinoma.

BACKGROUND: Little is known about the prognostic impact of cirrhosis on long-term survival of patients with combined hepatocellular-cholangiocarcinoma (cHCC-CC) after hepatic resection. The aim of this study was to elucidate the long-term outcome of hepatectomy in cHCC-CC patients with cirrhosis. METHODS: A total of 144 patients who underwent curative hepatectomy for cHCC-CC were divided into two groups: cirrhotic group (n = 91) and noncirrhotic group (n = 53). Long-term postoperative outcomes were compared between the two groups. RESULTS: Patients with cirrhosis had worse preoperative liver function, higher frequency of HBV infection, and smaller tumor size in comparison to those without cirrhosis. The 5-year overall survival rate in cirrhotic group was significantly lower than that in non-cirrhotic group (34.5% versus 54.1%, P = 0.032). The cancer recurrence-related death rate was similar between the two groups (46.2% versus 39.6%, P = 0.446), while the hepatic insufficiency-related death rate was higher in cirrhotic group (12.1% versus 1.9%, P = 0.033). Multivariate analysis indicated that cirrhosis was an independent prognostic factor of poor overall survival (hazard ratio 2.072, 95% confidence interval 1.041-4.123; P = 0.038). CONCLUSIONS: The presence of cirrhosis is significantly associated with poor prognosis in cHCC-CC patietns after surgical resection, possibly due to decreased liver function.

Isolated Roux-en-Y reconstruction versus conventional reconstruction after pancreaticoduodenectomy.

BACKGROUND: Pancreatic fistula (PF) is the major cause for morbidity and mortality following pancreaticoduodenectomy. The primary aim of this study was to compare the occurrence rate of postoperative PF between isolated Roux-en-Y reconstruction (RYR) and conventional reconstruction (CR) after pancreaticoduodenectomy. METHODS: Data of 43 patients who underwent RYC were compared with those of a pair-matched equal number of patients undergoing CR. We also performed a meta-analysis of comparative studies of the two procedures. RESULTS: The case-matched analysis showed no significant difference in PF occurrence between RYR and CR groups (23.3% versus 25.6%; P = 0.80). Meta-analysis of 1498 patients further confirmed this finding, showing a pooled odds ratio of 1.14 (95% confidence intervals, 0.82-1.58; P = 0.43). CONCLUSION: The use of RYR for pancreaticojejunostomy does not seem to decrease the occurrence rate of postoperative PF in patients undergoing pancreaticoduodenectomy.

Preoperative Antibiotic Prophylaxis Does Not Reduce the Risk of Postoperative Infectious Complications in Patients Undergoing Elective Hepatectomy.

BACKGROUND AND AIM: Postoperative infection is not uncommon after hepatectomy. This study assessed the effectiveness of preoperative antibiotic prophylaxis in elective hepatectomy in a randomized clinical trial setting. METHODS: A total of 120 patients who were scheduled to undergo elective hepatectomy were equally randomized to receive either intravenous cefuroxime 1.5 g (group A) or placebo (group B) within 30 min prior to skin incision. RESULTS: Overall, postoperative infection occurred in 26 (21.6 %) of the 120 patients. There was no statistically significant difference between groups A and B in the incidence of overall infection (23.3 vs. 20.0 %, P = 0.658), surgical site infection (13.3 vs. 15 %, P = 0.793), and remote site infection (13.3 vs. 11.7 %, P = 0.783). CONCLUSION: The use of preoperative antibiotic prophylaxis as a routine practice in patients undergoing elective hepatectomy is unnecessary because it does not reduce the risk of postoperative infectious complications.

Postoperative complications affect early recurrence of hepatocellular carcinoma after curative resection.

BACKGROUND: Postoperative recurrence remains the major cause of death after curative resection for hepatocellular carcinoma (HCC). This study was conducted to evaluate the impact of postoperative complications on HCC recurrence after curative resection. METHODS: The postoperative outcomes of 274 HCC patients who underwent curative resection were analysed retrospectively. RESULTS: Of the 247 HCC patients, 103 (37.6 %) patients developed postoperative complications. The occurrence of postoperative complications was found to be associated with a significantly higher tumor recurrence (76.2 % vs. 56.6 %, P = 0.002) and a lower 5-year overall survival rate (27.7 % vs. 42.1 %; P = 0.037) as compared with those without complications. Regarding the recurrence pattern, early recurrence (≤2 years) was more frequently seen in patients with complications than that in patients without complications (54.5 % vs.38.6 %; P = 0.011). Multivariate analysis indicated that postoperative complications occurrence was an independent risk factor for early recurrence (odds ratio [OR] 2.223; 95 % confidence intervals [95 % CI] 1.161-4.258, P = 0.016) and poor overall survival (OR 1.413; 95 % CI, 1.012-1.971, P = 0.042). CONCLUSIONS: The results of the present study indicate that the occurrence of postoperative complications is a predictive factor for HCC recurrence after curative hepatectomy, especially for early recurrence.

Prognosis after resection of hepatitis B virus-related hepatocellular carcinoma originating from non-cirrhotic liver.

BACKGROUND: Long-term prognosis after resection of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) originating from non-cirrhotic liver is not fully clarified. METHODS: A total of 183 patients who underwent curative hepatectomy for HCC without cirrhosis were classified into two groups: HBV infection group (n = 124) and non-HBV infection group (n = 59). Long-term postoperative outcomes were compared between the two groups. RESULTS: The 5-year postoperative overall survival (OS) and disease-free survival (DFS) were 42.6 and 39.0 %, respectively, in the HBV infection group versus 52.3 and 46.5 % in the non-HBV infection group (both p > 0.05). When patients were subdivided according to TNM stages, OS in stages II or III HCC patients was similar between the two groups. In contrast, OS and DFS were significantly worse in stage I patients with HBV infection than those in stage I patients without HBV infection (p = 0.041 and 0.038, respectively). Preoperative serum HBV DNA >4 log10 copies/mL and vascular invasion were independent factors associated with poor prognosis (p = 0.034 and 0.017, respectively) for patients with HBV infection. CONCLUSIONS: After hepatic resection for HCC in non-cirrhotic liver, patients with HBV infection with early-stage tumors had worse prognosis than patients without HBV infection, possibly due to the carcinogenetic potential of viral hepatitis in the remnant liver. Antiviral therapy should be considered after hepatectomy in patients with high HBV DNA levels.

Distal pancreatectomy with en bloc celiac axis resection for pancreatic body-tail cancer: Is it justified?

BACKGROUND: The aim of this study was to evaluate the safety and efficacy of distal pancreatectomy with en bloc celiac axis resection (DP-CAR) for pancreatic body-tail cancer. MATERIAL AND METHODS: The medical records of 12 patients who underwent DP-CAR for pancreatic body-tail cancer were retrospectively studied, together with a literature review of studies including at least 3 cases of DP-CAR. RESULTS: There were no deaths among our 12 cases. Postoperative morbidity developed in 9 cases and was successfully managed by non-surgical treatment. No patients developed ischemic complications. Median overall survival was 10 months. A total of 19 studies involving 203 patients who underwent DP-CAR were included in the literature review. The overall morbidity and mortality rates were 50.2% and 3.0%, respectively. The overall median survival after surgery ranged from 9.3 to 26 months. CONCLUSIONS: DP-CAR is a safe and effective treatment for patients with locally advanced pancreatic body-tail cancer.

Efficacy of surgical resection for pulmonary metastases from hepatocellular carcinoma.

BACKGROUND: The lung is one of the most common sites for extrahepatic metastasis from hepatocellular carcinoma (HCC). This study aimed to assess the efficacy of surgical resection for pulmonary metastases from HCC. MATERIAL AND METHODS: The medical records of 9 patients who underwent pulmonary metastasectomy from HCC at 2 institutions were retrospectively studied, together with a review of studies reporting the outcomes of at least 5 patients in the Chinese and English languages. RESULTS: There were no perioperative deaths or major complications. The 1-, 3-, and 5-year overall survival rate after surgery was 100%, 44.4%, and 33.3%, respectively. A total of 19 studies involving 443 patients who underwent pulmonary metastasectomy for metastasis of HCC were included in the literature review. The median mortality rate was 0% (range, 0-7.1%). The median survival ranged from 10.7 to 77 (median=33.2) months, and the 5-year overall survival rate ranged from 11.5% to 75% (median=36%). CONCLUSIONS: Surgical resection is a safe and effective treatment in selected patients with pulmonary metastases from HCC.

Pancreatic fistula after central pancreatectomy: case series and review of the literature.

BACKGROUND: Postoperative pancreatic fistula is one of the most common complications after pancreatectomy. This study aimed to assess the occurrence and severity of pancreatic fistula after central pancreatectomy. METHODS: The medical records of 13 patients who had undergone central pancreatectomy were retrospectively studied, together with a literature review of studies including at least five cases of central pancreatectomy. Pancreatic fistula was defined and graded according to the recommendations of the International Study Group on Pancreatic Fistula (ISGPF). RESULTS: No death was observed in the 13 patients. Pancreatic fistula developed in 7 patients and was successfully treated non-operatively. None of these patients required re-operation. A total of 40 studies involving 867 patients who underwent central pancreatectomy were reviewed. The overall pancreatic fistula rate of the patients was 33.4% (0-100%). Of 279 patients, 250 (89.6%) had grade A or B fistulae of ISGPF and were treated non-operatively, and the remaining 29 (10.4%) had grade C fistulae of ISGPF. In 194 patients, 15 (7.7%) were re-operated upon. Only one patient with grade C fistula of ISGPF died from multiple organ failure after re-operation. CONCLUSION: Despite the relatively high occurrence, most pancreatic fistulae after central pancreatectomy are recognized a grade A or B fistula of ISGPF, which can be treated conservatively or by mini-invasive approaches.
