ABSTRACT
Objective To investigate the clinical efficacy of pancreaticoduodenectomy (PD) and duodenumpreserving pancreatic head resection (DPPHR,including Beger,Frey and Berne procedures)for the treatment of chronic pancreatitis (CP) with mass in the head of the pancreas.Methods The clinical data of 48 patients with CP who were admitted to the Armed Police Corps Hospital of Hunan province(13) and the Third Xiangya Hospital of Central South University (35) between January 2007 and December 2013 were retrospectively analyzed.The operation methods were selected according to clinical symptoms,imaging findings and intraoperative pathological examinations.Twenty-three patients receiving PD (Whipple procedure or pylorus-preserving PD) were allocated into PD group and 25 receiving DPPHR (Beger,Frey and Berne procedures) were allocated into DPPHR group.The operation time,volume of intraoperative blood loss,rate of postoperative pain relief,changes of pancreatic endocrine and exocrine function,complications,duration of hospital stay and hospital expenses in the 2 groups were analyzed.Patients were followed up by telephone interview and outpatient examination up to September 2014.Measurement data with normal distribution were presented as (x) ± s.Comparison between groups was analyzed using the t test.Count data were analyzed using chi-square test or Fisher exact probability.Results Of the 23 patients in the PD group,15 patients received Whipple procedure and 8 patients received pylorus preserving PD.Of 25 patients in the DPPHR group,8 patients received Beger procedure,13 patients received Frey procedure and 4 patients received Berne procedure.The operation time and volume of intraoperative blood loss were (5.5 ± 0.4) hours,(372 ± 174) mL in the PD group,and (4.2 ± 0.6) hours,(272 ± 114) mL in the DPPHR group,showing significant differences between the 2 groups (t =8.712,2.375,P ＜ 0.05).Three patients had massive hemorrhage in the PD group and 2 patients receiving Beger procedure had massive hemorrhage due to portal vein injury,with no significant difference (x2=0.010,P ＞ 0.05).The intraoperative pathologic examinations of frozen section showed chronic inflammation in all pancreatic tissue samples with fibrous tissue proliferations.Overall pain relief rate was 95.7％ (22/23) in the PD group,including 20 complete remissions and 2 partial remissions,and overall pain relief rate was 92.0％ (23/25) in the PD group,including 18 complete remissions and 5 partial remissions,which were no different in overall pain relief rate (x2 =0.000,P ＞ 0.05).The morbidity of postoperative diabetes mellitus and dyspepsia with fatty diarrhea were 38.9％ (7/18) and 35.7％ (5/14) in the PD group,which were no different from 9.5％ (2/21) and 20.0％ (3/15) in the DPPHR group (x2=3.200,0.281,P ＞0.05).The incidence of postoperative complication was 30.4％ (7/23) in the PD group,including 1 case of intra-abdominal hemorrhage,pancreatic fistula and localized peritonitis,1 case of pancreatic fistula,2 cases of biliary fistula,3 cases of delayed gastric emptying.Patients with pancreatic fistula and biliary fistula recovered after 1-week sufficient drainage.The incidence of postoperative complication was 4.0％ (1/25) in the DPPHR group,including 1 case of pancreatic fistula,showing significant difference in incidence of postoperative complication (x2=4.274,P ＜ 0.05).The duration of postoperative stay and hospital expense were (12.4 ± 2.5) days and (57 751 ± 6 772) yuan in the PD group,which were significantly different from (8.2 ± 1.8) days and (49 109 ± 6 168)yuan in the DPPHR group (t =6.576,4.645,P ＜ 0.05).Forty-eight patients were followed up with a median time of 51.6 months (9.0-92.0 months).Of the 2 patients died,1 patient who underwent Frey procedure died 3 months after diagnosis of pancreatic cancer due to epigastric pain at postoperative month 6,the other died 2 years later due to cardiovascular disease.Among 48 patients with follow-up,1 received biliary-intestine drainage 6 months later and other patients had no recurrence or canceration.Conclusions DPPHR is safe and effective for chronic pancreatitis with mass in the head of the pancreas,having advantages such as shorter duration of operation,less intraoperative hemorrhage,faster postoperative recover,shorter duration of hospital stay and delayed hypofunction of pancreatic endocrine and exocrine function.But DPPHR cannot completely replace PD,It is necessary to master indications for all kinds of operations and choose proper operative approaches based on lesion characteristics.
ABSTRACT
Objective To investigate the clinical efficacy of treatment for chronic pancreatitis and mass in the head of the pancreas.Methods The clinical data of 19 patients with chronic pancreatitis with mass in the head of the pancreas who were admitted to the China-Japan Union Hospital of Jilin University from May 2008 to May 2013 were retrospectively analyzed,including 2 patients with gallstone.Methods of treatment were selected by in traoperative pathological results.All the patients were followed up by outpatient examination and telephone interview till January 2014.Results The operations of the 19 patients were successfully done,including 11 with pancreaticoduodenectomy,5 with exploratory laparotomy and 3 with the laparoscopic cholecystectomy and choledochojejunostomy.The operation time and intraoperative blood loss were (249± 140)minutes (50-390 minutes) and (320 ± 260)mL (50-900 mL).The postoperative mean time of recovery of gastrointestinal function and duration of postoperative hospital stay were 3.0 days (2.0-6.0 days) and 22.6 days (8.0-30.0 days) after the operation.The mean casein-IgG4 of 12 patients was higher (2.64 g/L) after operation.Five patients with operation-related complication were cured after symptomatic treatment,among 2 patients with leakage of the pancreatic fluid,2 with operative incision fat necrosis and liquefaction and 1 with bile leakage.No patients died perioperatively.Nineteen patients were followed up for 11.0 months to 36.0 months with the median time of 28.2 months.The pancreatic head mass of 8 patients with non-pancreaticoduodenectomy were reduced or disappeared by a computed tomography (CT) or magnetic resonance imaging (MRI) rescan,who were treated by the oral prednisone.No complications were detected in the other 11 patients with pancreaticoduodenectomy.Conclusion Method of surgery or medicine treatment for atypical mass in the head of the pancreas is selected according to the pathology results by effective communication with patients and family members,exploratory laparotomy and interpretative aspiration biopsy.
ABSTRACT
Objective To investigate the clinical efficacy of two types of duodenum-preserving pancreatic head resection (Beger procedure and Berne procedure) for chronic pancreatitis with mass in the head of the pancreas.Methods The clinical data of 46 patients with chronic pancreatitis and mass in the head of the pancreas who were admitted to the Affiliated Hospital of Guiyang Medical College from September 2008 to April 2012 were retrospectively analyzed.There were 24 patients received Beger procedure (Beger group),and 22 received Beme procedure (Berne group).The complications,life quality and pain after the operation were evaluated.Patients were followed up via phone call and out-patient examination till April 2013.The measurement data were analyzed using the Mann-Whitney U test,and the constituent ratios were compared using the chi-square test.Results The operation time and volume of blood loss were (377 ± 21) minutes and (746 ± 129) mL in the Beger group,and (323 ± 17) minutes and (577 ± 111)mL in the Berne group,with significant difference between the 2 groups (U=14.0,88.0,P ＜0.05).Four patients in the Beger group and 1 in the Berne group were complicated with pancreatic leakage,with no significant difference between the 2 groups (x2=0.714,P ＞ 0.05).The scores of life quality evaluation (physical condition,work capacity,cognitive ability,emotion,social competence and overall life quality) were 82 ± 14,74±24,90 ± 18,78±20,83 ± 18,73 ± 18 in the Beger group,and 79 ± 16,71 ±20,92 ±21,76 ± 18,80 ±21,70 ± 16 in the Berne group,with no significant difference between the 2 groups (U =177.5,183.5,187.5,178.0,189.5,192.0,P ＞ 0.05).The scores of symptom evaluation (fatigue,nausea and vomitting,pain,anorexia,dyspnea,sleep disorders,obstipation,diarrhea,financial worries) were 28 ± 16,24 ± 10,20±12,23 ± 14,4 ± 1,32 ± 12,6 ±2,18 ± 14,36± 18 in the Beger group,and 26 ± 18,26 ±20,22 ± 16,26 ± 16,3 ± 1,30 ± 10,5 ± 1,16 ± 12,38 ± 20 in the Berne group,with no significant difference between the 2 groups (U=194.5,215.5,182.5,180.5,213.0,199.0,195.0,184.5,181.5,P＞0.05).In the Beget group,19 patients did not have acute onset of pain,and 5 patients had acute onset of pain once a year; 6 patients were administered antalgesic occasionally.In the Berne group,20 patients did not have acute onset of pain,and 2 patients had acute onset of pain once a year; 4 patients were administered antalgesic occasionally,with no significant difference between the 2 groups (x2=0.485,0.041,P ＞ 0.05).All the patients were followed up,and the median time of follow-up was 36.3 months.No perforation of duodenum and steatorrhea was observed.No patient died perioperatively.Conclusion The clinical efficacy of the Berne procedure is similar to that of the Beger procedure,while the Berne procedure has advantages of easy manipulation and less operation time.
ABSTRACT
With continuous research of the formation mechanism of chronic pancreatitis with mass in the head of the pancreas and its relation with pancreatic cancer,and steady improvement of the operation safety,the number of operation for the chronic pancreatitis with mass in the head of the pancreas is increasing.On the other hand,with the improvement of the accuracy of preoperative diagnosis,Tru-cut intraoperative biopsy is increasingly applied to patients with negative results of preoperative ultrasonography biopsy,which is important for the surgical procedure selection.With the premise of effective treatment,continous improvement of treatment strategies to the chronic pancreatitis with mass in the head of the pancreas can maximize the benefit of patients.
