Relationship between pancreatic parenchyma loss and early postoperative hyperglycemia in patients with benign pancreatic diseases

Objective To evaluate the relationship between pancreatic parenchyma loss and early postoperative hyperglycemia in patients with benign pancreatic diseases. Methods A total of 171 patients with benign pancreatic tumors or chronic pancreatitis, whose preoperative fasting blood glucose (FBG) was normal and who underwent partial pancreatectomy were reviewed. The pancreatic volume was measured by CT imaging before and after the operation. According to their different pancreatic resection volume (PRV), 171 patients were divided into five groups: < 30%, 30%–39%, 40%–49%, 50%–59%, and ≥ 60%. The correlation between the PRV and postoperative FBG was investigated. According to the postoperative FBG value, the patients were divided into a hyperglycemia group (HG) and nonhyperglycemia group (non-HG) to explore the best cutoff value of the PRV between the two groups. Results There were significant differences in the postoperative FBG among the five groups (PRV < 30%, 30%–39%, 40%–49%, 50%–59%, and ≥ 60%). The PRV was positively correlated with postoperative FBG in the benign tumor group and chronic pancreatitis group (R = 0.727 and 0.651, respectively). ROC curve analysis showed that the best cutoff value of the PRV between the HG (n = 84) and non-HG (n = 87) was 39.95% with an AUC = 0.898; the sensitivity was 89.29%, and the specificity was 82.76%. Conclusion There was a linear positive correlation between the postoperative FBG level and PRV. Patients with a PRV ≥ 40% are more likely to develop early postoperative hyperglycemia.

Acinar cell cystadenoma of the pancreatic head

Acinar cell cystadenoma is one of the rarest benign pancreatic tumors. A clinical case of acinar cell cystadenoma of the pancreatic head in a 67-year-old patient is presented. The tumor was detected during a routine examination. The patient was undergoing surgery, enucleation of the neoplasm was performed. With a planned histologic examination and immunohistochemical analysis the diagnosis was confirmed. Surgical tactics depend on the location, size of the tumor and position to the adjacent structures. Given the benign nature of tumor, preference should be given to organpreserving interventions.

Laparoscopic interventions in the pancreas: an 11-year experience of a specialized center

Introduction:Due to anatomical and functional specifics of the pancreas, its surgery emerged somewhat later than that of other areas of abdominal surgery, i.e. in the last 25 to 30 years of the last century. Minimally invasive laparoscopic interventions on the pancreas are still used insufficiently.Aim: To evaluate an 11-year experience of various laparoscopic interventions in the pancreas accumulated by one surgical team.Materials and methods:From November 2007 to May 2018, 371 patients (153 male and 218 female) underwent various laparoscopic pancreatic procedures for cancers of the biliopancreatoduodenal zone (n = 260), benign pancreatic tumors (n = 37), and chronic pancreatitis (n = 74). We performed 245 laparoscopic pancreaticoduodenal resections, 52 laparoscopic distal resections (LDR), 35 laparoscopic Frey procedures (FP), 18 laparoscopic total duodenopancreatectomies, 8 laparoscopic longitudinal pancreaticojejunostomies (LLPJ), 8 laparoscopic cystoenterostomies (LCE), 3 enucleations, and 2 Beger procedures (BP).Results:Laparoscopic gastropancreatoduodenal resection was performed in 197 (80.4%) cases and pylorus preserving pancreatoduodenal resection in 48 (19.6%) cases. The duration of the procedures was 412 ± 101 minutes, with blood loss volume of 220 ± 152 ml, and postoperative hospital stay of 19 ± 9 days. LDR was done laparoscopically in 50 (96.2%) patients; its duration was 228 ± 74 minutes, blood loss 40 ± 50 ml, and postoperative hospital stay 8 ± 5 days. FP, LLPJ, BP, and LCE were performed laparoscopically in 53 (93%) cases. FP lasted for 436 ± 95, LLPJ for 406 ± 82, BP for 585 ± 134, and LCE for 327 ± 90 minutes. The respective volumes of blood loos were 227 ± 217 mL in FP, 150 ± 156 mL in LLPJ, 175 ± 106 mL in BP, and 60 ± 90 mL in LCE. The postoperative hospital stay lasted for 8 ± 4 days after FP, 9 ± 7 days after LLPJ, 4.5 ± 0.7 days after BP, and 10 ± 9 days after LCE.Conclusion:Laparoscopic surgery of the pancreas is associated with minimal blood loss, absence of wound infection, and more rapid patient activation and rehabilitation. Compliance with the necessary requirements to implementation of laparoscopic technologies in high-volume centers should improve surgical results.

Laparoscopic Enucleation of Benign Pancreatic Tumors

Benign pancreatic tumor enucleations have been performed since 1996. Endocrine tumors (ET) are rare yet they represent about 2/3 of the laparoscopic enucleations, a topic still in debate. Preoperative imaging routinely comprises a CT scan but endoscopic ultrasound is mandatory for localizing the tumor and guided biopsy-aspiration. Trocars have to be positioned to avoid “fencing” with the instruments. A Kocher maneuver may be necessary for accessing deep or posterior tumors. Bipolar electrocautery and harmonic scalpel ensure better hemostasis than the monopolar cautery hook. The raw surface can be covered with hemostatics or fibrin glue. The mean operating time is 2 hours. Forced conversions, due mainly to hemorrhage or insufficient exposure, are rare (9%). Pancreatic fistula, the main postoperative complication, affects up to one third of the patients and does not depend on the choice of dissection instruments, management of the remaining cavity or somatostatin use. A risk factor is the location of the tumor at less than 2mm from the main pancreatic duct. Necrotic pancreatitis, pancreatic pseudocyst and duodenal fistula contribute to a surgical morbidity of 60%. Although safe and technically feasible enucleation still has to be considered a low mortality but high morbidity procedure.
