Postpancreatectomy acute pancreatitis (PPAP) is an acute inflammation of the remnant pancreas in the early postoperative period caused by a variety of factors. With the progress of related research,PPAP has been confirmed as an independent risk factor for many severe complications such as postoperative pancreatic fistula. In some cases, it progresses to necrotizing PPAP, increasing the risk of mortality. Currently, the International Study Group for Pancreatic Surgery has standardized and graded PPAP as an independent complication, taking into account factors including serum amylase, radiological features, and clinical impact. This review summarizes how the concept of PPAP was proposed, as well as the latest progress in the research related to its etiology, prognosis, prevention, and treatment. However, given the large heterogeneity of relevant studies and the fact that they were mostly retrospective, in the future, it is necessary to place more emphasis on PPAP and elucidate the problems through more standardized studies to optimize strategies for the prevention and management of complications after pancreatic surgery.

A 50-year-old man with a 15-year history of elevated blood glucose and an approximately 2-year history of diarrhea was admitted to the Peking Union Medical College Hospital. The initial diagnosis was type 2 diabetes. After repeated pancreatitis and pancreatoduodenectomy, severe pancreatic endocrine and exocrine dysfunction including alternating high and low blood glucose and fat diarrhea occurred. Tests for type 1 diabetes-related antibodies were all negative, C-peptide levels were substantially reduced, fat-soluble vitamin levels were reduced, and there was no obvious insulin resistance. Therefore, a diagnosis of pancreatic diabetes was clear. The patient was given small doses of insulin and supplementary pancreatin and micronutrients. Diarrhea was relieved and blood glucose was controlled. The purpose of this article is to raise clinicians' awareness of the possibility of pancreatic diabetes after pancreatitis or pancreatic surgery. Timely intervention and monitoring may reduce the occurrence of complications.

OBJECTIVE: To investigate the safety of laparoscopic pancreaticoduodenectomy (LPD) in elderly patients and the related risk factors admitted to the intensive care unit (ICU) after LPD. METHODS: The perioperative data of patients who underwent LPD in Tianjin Medical University General Hospital from February 2017 to June 2023 were retrospectively collected, including basic data, preoperative laboratory indicators, intraoperative and postoperative indicators, pathological results (tumor size, lymph node dissection and pathological type), postoperative complications, ICU postoperative management and prognosis. The patients were divided into the elderly group (≥ 65 years) and the non-elderly group (< 65 years) according to age. Perioperative data between two groups were compared. Kaplan-Meier survival curve was drawn to analyze the survival rate of the elderly group and the non-elderly group, and the pancreatic head carcinoma group and other type of tumors group after LPD. Logistic regression was used to analyze the risk factors of ICU stay (length of ICU stay > 1 day) after LPD in elderly patients. The receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of this risk factor for ICU stay after LPD in elderly patients. RESULTS: A total of 160 patients were enrolled, including 57 cases in the elderly group (17 cases of vascular reconstruction) and 103 cases in the non-elderly group (40 cases of vascular reconstruction). All patients underwent R0 resection and were transferred to the comprehensive ICU for treatment. The follow-up time of patients with malignant tumors was 43 (6, 72) months. The elderly group had significantly longer surgery time, postoperative hospital stay and oral feeding time than the non-elderly group, and the incidence of delayed gastric emptying (DGE) was significantly higher than that in the non-elderly group. There were no significant differences in intraoperative blood transfusion rate, intraoperative blood loss, pathological results, short-term and severe postoperative complications, reoperation rate and 90-day mortality between the two groups. In patients with vascular resection reconstruction, the intraoperative blood loss in the elderly group was significantly higher than that in the non-elderly group, and the operation time and postoperative hospital stay were significantly longer. During ICU, the acute physiology and chronic health evaluation II [APACHE II: 12 (9, 14) vs. 8 (7, 10)], sequential organ failure assessment [SOFA: 6 (4, 8) vs. 3 (2, 5)] within 24 hours after admission to ICU were significantly increased in the elderly group (both P < 0.05), the time of mechanical ventilation [hours: 12 (10, 15) vs. 9 (5, 13)] and the length of ICU stay [days: 2 (1, 2) vs. 1 (1, 1)] were significantly increased in the elderly group (both P < 0.05), and the proportion of multi-disciplinary team (MDT) was also significantly increased in the elderly group (33.3% vs. 17.4%, P < 0.05), there were no significant differences in the levels of hemoglobin (Hb), albumin, and blood lactic acid between the two groups. Logistic regression analysis showed that the APACHE II score was an independent risk factor for ICU stay after LPD in elderly patients (β = 1.737, P = 0.028). ROC curve showed that the prediction performance was the best when the APACHE II score was 13, with the sensitivity of 72.41% and the specificity of 96.43%, and the area under the ROC curve (AUC) of 0.884. The Kaplan-Meier survival curve showed that there were no significant difference in median survival time (months: 24.1 vs. 24.7) and 5-year survival rate (19.01% vs. 19.02%) between the elderly group (52 cases) and the non-elderly group (92 cases) among the 144 patients with malignant tumors (both P > 0.05). The median survival time in the pancreatic head carcinoma group was significantly shorter than that in the other tumors group (63 cases; months: 20.2 vs. 40.1, P < 0.05), 5-year survival rate was significantly lower than that in the other tumors group (21.98% vs. 30.91%, P < 0.05). CONCLUSIONS LPD is a safe and feasible treatment for elderly patients. APACHE II score has a certain predictive value for ICU stay after LPD in elderly patients.

Pancreatic cancer was considered to be one of the contraindications of laparoscopic pancreaticoduodenectomy, but a large number of studies have shown that laparoscopic pancreaticoduodenectomy is safe and feasible for surgeons who have passed the learning curve in high-volume hospitals.Laparoscopic pancreaticoduodenectomy can provide high-resolution intraoperative exploration and unique operative perspective,which can help to reduce intraoperative and postoperative complications,dissect lymph nodes more thoroughly and reduce intraoperative metastasis of tumors,so as to promote the development of postoperative adjuvant therapy and improve patients' quality of life.However,due to the long learning curve and unclear survival outcome, the application of laparoscopic pancreaticoduodenectomy in patients with pancreatic cancer is still controversial.This article summarizes the existing literature and the experience of the author's team,exploring the value and controversy of laparoscopic pancreaticoduodenectomy in the treatment of pancreatic cancer.Further,suggestions are put forward on how to improve the laparoscopic pancreaticoduodenectomy in China.

Objective: To identify the risk factors of newly developed nonalcoholic fatty liver disease(NAFLD) after pancreaticoduodenectomy(PD). Methods: The clinical data of 130 patients who had undergone PD at Department of Hepatopancreatobiliary Surgery, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University from June 2018 to December 2020 were collected retrospectively. There were 74 males and 56 females, with age(M(IQR)) of 62(16) years (range: 22 to 84 years). Twenty-nine patients who developed NAFLD were divided into NAFLD group and 101 patients who did not suffer NAFLD were divided into no NAFLD group. Observation indications included:(1)preoperative demographics,intraoperative and postoperative characteristics; (2)the risk factors of newly developed NAFLD after PD. Count data were analyzed using χ² test or Fisher's exact test. Measurement data were analyzed by student t test or Mann-Whitney U test. Multivariate analysis was performed using Logistic regression model with a stepwise forward approach. Results: All 130 patients successfully underwent PD and 29 cases(22.3%) developed NAFLD in 6 months after PD. The results of univariate analysis showed that gender,diabetic mellitus,the level of triglyceride preoperatively,and pancreatic ductal adenocarcinoma were the related factors of the development of NAFLD after PD(t=-2.655, χ²=4.563,U=-2.192,χ²=7.044;all P<0.05).Multivariate analysis revealed that gender,body mass index and pancreatic ductal adenocarcinoma were independent risk factors for the development of NAFLD after PD(OR=2.849,1.214,4.165,all P<0.05). Conclusion: Gender, body mass index and pancreatic ductal adenocarcinoma were independent risk factors for the development of NAFLD after PD.

Pancreaticojejunostomy is the most common anastomosis following pancreaticoduodenectomy and middle pancreatectomy. The detailed surgical technics of pancreaticojejunostomy vary dramatically, but none of them can achieve zero fistula rate. In recent years,with the development of new surgical concept,application of new surgical technology, high-tech materials and instruments,the incidence of pancreatic fistula has decreased. At the same time,researches on investigating the risk factors of pancreaticojejunostomy are gradually deepening. Based on years of surgical experience on pancreaticojejunostomy and current literatures, this paper analyzes the factors affecting the effect of pancreaticojejunostomy, such as the patient's basic physical state,pancreatic texture and diameter of the pancreatic duct,pathology and course of the disease,surgical technology and perioperative management,and summarizes six technical principles for pancreaticojejunostomy to be shared with surgical comrades:appropriate tension,protection of blood supply,hermetic closure of pancreatic section,accurate connection of pancreatic duct and intestinal mucosa,individualization,learning and accumulation of experience.

OBJECTIVETo investigate the effect of utilizing octreotide during perioperative period on pancreatic fistula after pancreaticoduodenectomy (PD).

METHODSThree hundreds and six patients admitted from January 2010 to October 2014, who prepared to undergo pancreaticoduodenectomy (PD) were randomly divided into octreotide group (147 cases) and control group (159 cases). In octreotide group, octreotide was used in subcutaneous injection instantly after PD, each 8 hours until postoperative 10(th) day, and patients in control group were injected with the same volume of saline. Differences of pancreatic fistula (Grade A, Grade B, Grade C), hospitalization days and treatment cost were compared. χ(2) test, t-test and Fisher exact test were used to analyzed to the data, respectively.

RESULTSNo statistical significance (P>0.05) between two groups in the incidence of pancreatic fistula after PD (Grade A: 8.8% vs. 10.2%, Grade B: 2.7% vs. 4.4%, Grade C: 0.7% vs. 1.3%; χ(2)=0.197, 0.700, 0.288; P=0.657, 0.403, 0.591), the length of hospitalization((12.1±1.2)days vs. (13.0±1.2)days)(t=1.711, P=0.104) and treatment cost (79 700±6 700 vs. 77 600±5 200)(t=1.378, P=0.185). When accompanied with high risk factors, such as soft texture of pancreas, pancreatic duct size less than 3 mm, BMI≥25 kg/m(2) and diabetes, compared with control group, octreotide group had the lower incidence rate of pancreatic fistula and clinical correlative pancreatic fistula(all P<0.05) after PD.

CONCLUSIONSGenerally, octreotide makes no contribution to reduce the incidence of pancreatic fistula after PD. However, for patients who is accompanied with high risk factors, such as soft texture of pancreas, pancreatic duct size less than 3 mm, BMI≥25 kg/m(2) and diabetes, octreotide can effectively prevent pancreatic fistula after PD.

OBJECTIVETo develop and test a scoring system to predict the risks of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy(PD).

METHODSClinic data and postoperative complications of the 445 consecutive patients who underwent a PD procedure between January 2008 and April 2015 in Peking University First Hospital were retrospectively collected and analyzed.The patients were randomly selected to modelling and validation sets at a ratio of 3∶1, respectively.The patient data were subjected to univariate and multivariate analysis in the modelling set of patients.A score predictive of POPF was designed and tested in the validation set.

RESULTSPOPF occurred in 88 of 334 patients(26.4%) in the modelling set.The multivariate analysis showed that body mass index (BMI, P<0.01) and pancreatic duct width(P=0.001) are associated with POPF independently.A risk score to predict POPF was constructed based on these factors and successfully tested.The area under the receiver operating characteristic curve were 0.829(95% CI: 0.777-0.881) on the modelling set and 0.885(95% CI: 0.825-0.945) on the validation set, respectively.

CONCLUSIONSBMI and pancreatic duct width were associated with POPF after PD. The preoperative assessment of a patient's risk for POPF is feasible.The present risk score is a valid tool to predict POPF in patients undergoing PD, to make the selection on anastomosis types, and to take precautions against POPF.

Pancreaticoduodenectomy (PD) is the most effective treatment for patients with pancreatic head or periampullary lesions. Two major strategies exist: pylorus-preserving pancreaticoduodenectomy (PPPD) and pylorus-resecting pancreaticoduodenectomy (PRPD). However, it is yet unclear regarding the morbidity after PPPD and PRPD. This study analyzed the morbidity after PPPD and PRPD to determine the optimal surgical treatment of masses in the pancreatic head or periampullary region. A systematic search of databases identifying randomized controlled trials (RCTs) from the Cochrane Library, PubMed, EMBASE and Web of Science was performed. Outcome was compared by postoperative morbidity including overall morbidity, pancreatic fistulas, wound infections, postoperative bleeding, biliary leakage, ascites and delayed gastric emptying (DGE) rate between PPPD and PRPD. The DGE rate in the PRPD subgroups (conventional PD [CPD] and subtotal stomach-preserving PD [SSPPD], respectively) was also analyzed. The results showed that 9 RCTs including 722 participants were included for meta-analysis. Among these RCTs, 7 manuscripts described PRPD as CPD, and 2 manuscripts described PRPD as SSPPD. There were no significant differences in the overall morbidity, pancreatic fistulas, wound infections, postoperative bleeding, or biliary leakage between PPPD and PRPD. There was a lower rate of DGE with PRPD than that with PPPD (RR=2.15, P=0.03, 95% CI, 1.09-4.23). Further subgroup analysis indicated a comparable DGE rate for the CPD but a lower DGE rate for the SSPPD group than the PPPD group. However, the result did not indicate any difference between CPD and SSPPD regarding the DGE rate (P=0.92). It is suggested that PPPD is comparable to PRPD in overall morbidity, pancreatic fistulas, wound infections, postoperative bleeding and biliary leakage. The current data are not sufficient to draw a conclusion regarding which surgical procedure is associated with a lower postoperative DGE rate. Our conclusions were limited by the available data. Further evaluations of RCTs are needed.
