ABSTRACT
Objective:To investigate the application value of laparoscopic duodenum-preserving pancreatic head resection (LDPPHR).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 25 patients undergoing LDPPHR in the Second Hospital of Hebei Medical University from November 2016 to November 2020 were collected. There were 7 males and 18 females, aged from 14 to 66 years, with a median age of 29 years. All the 25 patients underwent LDPPHR. Observation indicators: (1) surgical situations; (2) postoperative histopathological examination; (3) follow-up. Follow-up was conducted using outpatient examination or telephone interview to detect the recovery of patients up to March 2021. Measurement data with skewed distribution were represented as M (range) and count data were descripted as absolute numbers. Results:(1) Surgical situations: all the 25 patients underwent LDPPHR successfully, including 23 cases undergoing total pancreatic head resection and 2 cases undergoing subtotal pancreatic head resection. The operation time and volume of intraoperative blood loss of 25 patients were 310 minutes (range, 207 to 540 minutes) and 200 mL (range, 50 to 800 mL), respectively. Of the 25 patients, 1 case was infused with 4 U of red blood cells and 400 mL of plasma, 1 case was infused with 500 mL of plasma, 1 case was infused with 600 mL of plasma and the remaining 22 cases were not infused with red blood cells or plasma. Of the 25 patients, 3 cases with pancreatic fistula of class B were discharged after drainage, 4 cases had biliary fistula including 2 cases undergoing symptoms disappeared after implantation of common bile duct stent by endoscopic retrograde cholangiopancreatography, 1 case recovering well with drainage, 1 case with postoperative perihepatic effusion undergoing symptoms disappeared after the treatment of drainage and common bile duct stent implantation, and the remaining 18 cases had no complications. The duration of postoperative hospital stay was 17 days (range, 9 to 27 days) of the 25 patients. (2) Postoperative histopathological examination: the tumor volume of the 25 patients was 6.0 cm×5.0 cm×2.0 cm (range, 1.0 cm×2.0 cm×1.5 cm to 10.0 cm×9.0 cm×8.0 cm). Results of the postoperative histopathological examination showed that there were 12 cases with pancreatic solid pseudopaillary neoplasm, 4 cases with intraductal papillary mucinous neoplasm, 3 cases with serous cystadenoma, 2 cases with mucinous cystadenoma, 1 case with neuroendocrine neoplasm, 1 case with pancreatic true cyst, 1 case with cholesterol crystals combined with calcification in the center of pancreatic nodules and 1 case with cavernous hemangioma of pancreas. (3) Follow-up: all the 25 patients were followed up for 4 months to 48 months, with a median follow-up time of 27 months. During the follow-up, 1 case of the 25 patients with postoperative diabetes controlled blood glucose in the normal range after regular injection of insulin, 1 case with fatty diarrhea had symptoms improved after oral supplement of pancreatic enzyme preparation, 1 case with preoperative intermittent dizziness, weakness of both lower limbs and hypoglycemia had the level of blood glucose returned to normal without any special treatment after operation, and the remaining 23 cases had no metabolic complications. None of the 25 patients had tumor malignant transformation, recurrence or death. No long-term complications such as delayed gastric emptying, bile duct stones or stricture occurred to the 25 patients.Conclusion:LDPPHR is safe and feasible for the treatment of benign or low-grade malignant tumors of the pancreatic head, with the advantage of preserving the integrity of digestive tract.

ABSTRACT
Objective To study the feasibility of laparoscopic pancreaticoduodenectomy ( LPD) in the treatment of pancreatic head cancer, and to analyze the short-term postoperative outcomes. Methods The clinical data of 57 patients with pancreatic head cancer who underwent laparoscopic pancreaticoduode-nectomy from April 2015 to November 2017 in the Second Hospital of Hebei Medical University were retro-spectively analyzed. Results Of the 57 patients, conversion to open surgery was required in 2 patients, and major venous resection and reconstruction were performed in 9 patients, including 8 end-to-end anastomosis, and 1 synthetic graft interposition. Total pancreatectomy was carried out in 4 patients. For the remaining 53 patients, pancreaticojejunal mucosal anastomoses were carried out in 50 patients, and sleeve pancreaticojeju-nostomy in 3 patients. The mean operative time and operative blood loss were 497 (240～720) min and 435 (50～3 000 ) ml, respectively. The mean postoperative hospital stay was 17. 7 ( 6. 0 ～59. 0 ) days. Postoperative complications were detected in 26. 3% (15/57) of patients, which included delayed gastric emptying (DGE) in 4 patients, Grade B pancreatic fistula (PF) in 4 patients, biliary fistula ( BF) in 2 patients, postpancreatectomy hemorrhage ( PPH) in 2 patients, intraabdominal infection in 1 patient and pulmonary infection in 2 patients. All the patients with DGE recovered with conservative treatment and they were discharged home. Reoperation was only required in the two patients with PPH. One patient died after the operation. The postoperative pathological results revealed pancreatic duct adenocarcinoma in 53 patients, adenosscale carcinoma in 1 patient and neuroendocrine carcinoma in 3 patients. The maximum and minimum tumor sizes were 7. 0 cm×5. 0 cm×3. 5 cm and 2. 5 cm×1. 5 ×1. 0 cm, respectively. The mean lymph nodes harvest and positive lymph node retrieval were 14(1～60) and 0. 7(0～3), respectively. Negative resection margins were obtained in 84. 2% (48/57) of patients. This study was censored on December 31, 2017. The follow-up for these patients ranged between 1 to 32 months. Mortality occurred in 21 patients, including 1 patient with a ruptured aneurysm 2 months after operation, 2 patients with GI bleeding 2 and 9 months respectively after operation, 1 patient with severe pulmonary infection and 17 patients with cancer recurrence with survival varying from 2 to 21 months. 35 patients were still alive. Conclusion Laparoscopic pancreaticoduodenectomy is a safe and feasible procedure for pancreatic head cancer.
ABSTRACT
Objective To explore the value of endoscopic retrograde cholangiopancreatography (ERCP) in patients with choledocholithiasis after Billroth Ⅱ gastrointestinal anastomosis.Methods A retrospective cohort study was conducted to retrospective review the data of 189 patients with choledocholithiasis treated by ERCP from December 2015 to November 2017 in Department of Hepatobiliary Surgery,Second Hospital of Hebei Medical University.According to the history of Billroth Ⅱ gastrointestinal anastomosis,the patients who have not undergone digestive surgery were divided into the normal group(n =167) and patients who have undergone digestive surgery were divided into reconstruction group (n =22).The operation time,the success rate of stone extraction,complications,the hospitalization time,total hospitalization expenses were compared between the two groups.Measurement data with normal distribution were represented as (Mean ± SD) and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range).Comparisons of count data were analyzed using the x2 test or Fisher exact probability.Results The operation time of the normal group was (40.18 ± 11.80) min,and the success rate of ERCP was 97.60％ (163/167),the operation time of reconstruction group was(61.81 ± 13.21) min,and the success rate of ERCP was 81.82％ (18/22),There were significant differences between the two groups (t =0.105,x2 =10.400,P ＜ 0.05).The complications,the hospitalization time and the total hospitalization expense of the normal group were 16.17％ (27/167),(3.47 ± 1.55) d,(20 620.69 ± 3 117.88) yuan,the reconstruction group were 18.18％ (4/22),(4.18 ± 2.08) d,(22 426.41 ±5 916.30) yuan,with no statistically significant difference (x2 =0.000,t =4.204),t =10.828,P ＞ 0.05).Conclusions ERCP is safe and feasible for patients with choledocholithiasis after Billroth Ⅱ gastrointestinal anastomosis.It also has a high success rate of stone removal and small trauma,which is worthy of promotion.
