ABSTRACT
Objective:To study the safety and efficacy of laparoscopic subtotal distal pancreatectomy using the arterial first approach in treatment of patients with pancreatic neck-body cancer after neoadjuvant chemotherapy.Methods:The clinical data of patients who underwent laparoscopic subtotal distal pancreatectomy after neoadjuvant chemotherapy at the Department of Pancreatic Surgery, Hunan Provincial People's Hospital from January 2019 to June 2021 were analyzed retrospectively. Seven patients were included in this study. There were 3 males and 4 females, aged 55(46, 67) years old. The clinical data analysed included chemotherapy, preoperative, intraoperative, postoperative and follow-up data. Follow up was done by outpatient visits, or contact using wechat or telephone.Results:Five borderline staged patients were treated with the AG chemotherapy regimen (gemcitabine+ albumin-bound paclitaxel), and two patients with locally advanced stage were treated with the mFOLFIRINOX chemotherapy regimen (oxaliplatin+ irinotecan+ calcium folate+ fluorouracil). All the 7 patients underwent portal vein/superior mesenteric vein resection and reconstruction using the superior mesenteric artery priority approach. The operation time was 400(350, 440) min, and the intraoperative blood loss was 300(150, 400) ml. Postoperative complications occurred in 2 patients with grade B pancreatic fistula and refractory ascites in 1 patient each. The postoperative hospital stay was 11(10, 14) days. All 7 patients underwent R 0 resection. During a follow-up period of 9 to 33 months, 5 patients were still alive without tumor, 1 patient survived with tumor, and 1 patient had died of recurrence. Conclusion:In selected cases, laparoscopic subtotal distal pancreatectomy for pancreatic neck-body cancer after neoadjuvant chemotherapy was safe and feasible.
ABSTRACT
Objective:To study the indications and clinical efficacy of video assisted small incision in treatment of infected pancreatic necrosis.Methods:A retrospective study was conducted on 27 patients with infected pancreatic necrosis treated by video assisted small incision at the Department of Pancreatic and Splenic Surgery, Hunan Provincial People's Hospital, from January 2018 to December 2019. The surgical approach, operation time, intraoperative blood loss, postoperative hospital stay and complications were analysed. Postoperative follow-up was carried out at outpatients’ clinic, and the patient's time to full recovery and long-term complications were studied.Results:The 27 patients successfully underwent the operations. There were 22 males and 5 females, aged (50.6±6.2) years. The treatment results were analyzed according to the different surgical approaches: the retroperitoneal approach group ( n=4); the omental sac approach group (n=14); the intercostal space approach group ( n=2); and the combined approach group ( n=7). The operation time was (85.3±31.6)min. The intraoperative blood loss was 65.0(45.2, 121.4)ml. The postoperative hospital stay was 23.0(12.5, 36.1)days. The incidence of complications (Clavien-Dindo grade Ⅲ and above) was 14.8%(4/27). There were 2 patients in this study who were admitted to the intensive care unit due to postoperative hemorrhage: 1 patient responded well to conservative treatment and the remaining patient required interventional treatment. Another patient because of poor results, underwent debridement by laparotomy 2 weeks after the operation. There was 1 patient who developed grade C pancreatic fistula which was cured by surgical treatment 6 months later. On follow-up, 2 patients developed colonic fistula 2 weeks after surgery and 2 patients gastric fistula 1 week and 3 weeks after surgery. These patients responded to conservative treatment. Conclusion:With proper case selection, video assisted small incision could safely and effectively be used to treat infected pancreatic necrosis.
ABSTRACT
Objective:To study the value of metastatic positivety in lymph nodes group 8a in deciding on extended lymph node dissection in pancreaticoduodenectomy(PD) for pancreatic head cancer.Methods:A retrospective study on 165 patients with pancreatic head cancer treated with PD at the Department of Pancreas and Spleen Surgery, Hepatobiliary Hospital of Hunan Provincial People's Hospital between January 2014 to June 2019 was performed. There were 101 males and 64 females with ages ranging from 38 to 75 (median 57) years. Patients who underwent standard lymph node dissection were included in the standard group ( n=88), and extended lymph node dissection in the extended group ( n=77). These patients were further divided into 4 subgroup. Subgroup A (standard PD in patients with negative nodes in group 8a, n=61), Subgroup B (extended PD in patients with negative nodes in group 8a, n=47), Subgroup C (standard PD in patients with positive nodes in group 8a, n=27), and Subgroup D (extended PD in patients with positive nodes in group 8a, n=30). The operation time, intraoperative blood loss, postoperative survival rates, complications were compared among the groups and subgroups. Results:The operation time and intraoperative blood loss of the standard group were (456.8±30.4) min and (264.28±101.14) ml, respectively, which were significantly lower than the extended group of (507.1±45.7) min and (388.9±155.3) ml (all P<0.05). The incidence of postoperative complications in the extended group (31.2%, 24/77) was significantly higher than that in the standard group (14.8%, 13/88) ( P<0.05). When compared with subgroup B, the cumulative survival rate of patients in subgroup A was not significantly different ( P>0.05). However, the cumulative survival rate of patients in subgroup C was significantly lower than that in subgroup D ( P<0.05). The cumulative survival rate of subgroup A was also significantly better than that of subgroup C ( P<0.05). There was no significant difference in the cumulative survival rates between group B and group D ( P>0.05). Conclusions:PD with extended lymph node dissection improved the survival rates in patients with cancer of the head of the pancreas with positive lymph nodes in group 8a. For these patients, extended lymph node dissection is recommended. With negative lymph nodes in group 8a, standard lymph node dissection is recommended.
ABSTRACT
Objective:To investigate the clinical efficacy of perihilar surgical techniques for diffuse hepatolithiasis.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 122 patients with diffuse hepatolithiasis who were admitted to Hunan Provincial People's Hospital from January 2010 to December 2015 were collected. There were 39 males and 83 females, aged from 21 to 82 years, with a median age of 51 years. After perihilar hepatectomy, the first, second and third divisions of hepatic ducts were opened longitudinally. Strictures in the bile ducts were relieved by stricturoplasty and internal bile duct anastomosis, and stones were removed by multiple methods under direct vision. After resection of severe atrophic liver segment along the plane of hepatic atrophy or bile duct stricture, T-tube or hepaticojejunos-tomy was used for internal drainage. Observation indicators: (1) surgical situations; (2) stricture relief and stone removal. (3) Follow-up. Follow-up was conducted by Wechat, telephone interview or outpatient examination. Patients were followed up once every 3 months in the postoperative 1 year through liver function and abdominal B-ultrasound examination. Subsequently, liver function and abdominal B-ultrasound were reexamined once a year. Magnetic resonance cholangiopancreato-graphy and computed tomography were performed when cholangitis or stone recurrence was suspected to analyze stone recurrence and patient survival. The follow-up was up to July 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers or percentages. Results:(1) Surgical situations: for the 122 patients, the operation time, hepatic portal occlusion time, volume of intraoperative blood loss, duration of postoperative hospital stay were (253±71)minutes, 15 minutes(range, 14?38 minutes), 200 mL(range, 100?1 100 mL), (12±5)days. Postoperative complications occurred to 40 of 122 patients. There were 9 cases of incision infection, 8 cases of bile leakage (5 cases of bile leakage at hepatic section, 3 cases of choledochojejunostomy leakage), 8 cases of septicemia, 7 cases of pleural effusion, 5 cases of abdominal abscess, 3 cases of liver failure, 1 case of biliary bleeding. Some patients had multiple complications. Among the 122 patients, 2 cases died after operation, including 1 case of postoperative liver failure and 1 case of disseminated intravascular coagulation caused by biliary-intestinal anastomotic leakage complicated with sepsis. Patients with bile leakage and abdominal abscess were improved after puncture and drainage under the guidance of B-ultrasound. Patients with cholangiojejunal anastomotic bleeding were embolized through the right hepatic artery. The other complications were improved after conservative treatment. (2) Stricture relief and stone removal: 85 of 88 patients with biliary stricture were relieved, with the stricture relief rate of 96.59%(85/88). Among the 122 patients, 103 cases had stones completely removed and 19 cases had residual stones. The immediate stone clearance rate was 84.43%(103/122). Of the 19 patients with residual stones, choledochoscopy was refused in 3 cases and choledochoscope lithotripsy was performed in 16 cases, of which 7 cases were removed and 9 cases were still residual stones. Of the 122 patients, 110 cases were finally removed stones, 12 cases were eventually residual stones, and the final stone clearance rate was 90.16%(110/122). (3) Follow-up: among the 122 patients, 120 cases including 110 cases with find stone removal and 10 cases with residual stones were followed up for (78±14)months. The 1-, 3, 5-year stone recurrence rates of 120 patients were 0.83%(1/120), 6.67%(8/120), 9.17%(11/120), respectively. The 1-, 3-, 5-year stone recurrence rates of 110 patients with final stone removal were 0, 5.45%(6/110), 5.45%(6/110), respectively. The number of cases with stone recurrence at postoperative 1-, 3- and 5-year of 10 patients with residual stones were 1, 2, 5 cases, respectively. Of 120 patients with follow-up, 1 case died of end-stage liver disease, and the other patients had good survival.Conclusion:Perihilar surgical techniques for diffuse hepatolithiasis is safe and effective.
ABSTRACT
Objective:To study and analyse the results of postoperative hemorrhage after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of patients who underwent LPD from May 2011 to December 2019 at Hunan Provincial People's Hospital were retrospectively analyzed. The clinical characteristics of patients, onset time of postoperative hemorrhage, location of postoperative hemorrhage, postoperative biliary fistula, pancreatic fistula, infection and other short-term complications, reoperation and mortality rates were analyzed.Results:Of 356 patients who underwent LPD in this study, there were 200 males and 156 females, aged (58.0±10.5) years. The postoperative complication rate was 33.1% (118/356), the reoperation rate was 6.5% (23/356), and the mortality rate was 2.5% (9/356). The most common complications were postoperative hemorrhage [15.2% (54/356)], pancreatic fistula [14.6%(52/356)] and abdominal infection [13.8%(49/356)]. The onset time of postoperative hemorrhage was usually in the 1st - 14th day, and the highest rate of postoperative hemorrhage was 3.9% (14/356) on the first day after surgery. The postoperative hemorrhage rate then showed a downward trend, but increased again on the 7th day. The extraluminal hemorrhage locations were relatively widely distributed, and the incidence of gastrointestinal anastomotic hemorrhage in patients with intraluminal hemorrhage was the highest [67.9%(19/28)]. Of the 9 patients who died, 7 were related to postoperative bleeding.Conclusions:LPD resulted in a high incidence of complications. Postoperative hemorrhage was a complication that had the greatest impact on short-term recovery of patients. It was also an important cause of reoperation and death. In addition to postoperative bleeding caused by pancreatic fistula, gastrointestinal anastomotic bleeding was also clinically important.
ABSTRACT
Objective@#To investigate the application value of real-time virtual sonography(RVS)in the diagnosis and treatment of complicated hepatolithiasis.@*Methods@#The retrospective and descriptive study was conducted. The clinical data of 10 patients with complicated hepatolithiasis who were admitted to Hunan Provincial People′s Hospital between October 2017 and March 2018 were collected. There were 3 males and 7 females, aged from 40 to 69 years, with an average age of 57 years. Patients received abdominal color Doppler ultrasound examination, magnetic resonance cholangiopancreatography, and upper abdominal spiral computed tomography (CT) thinly scanning + enhanced examination. Data of CT examination were imported into RVS. RVS was used to locate hepatolithiasis, relationship between stones and vessels, anatomy of bile ducts and vessels in hepatic hilus. Surgical methods included RVS-guided hilar cholangiotomy, biliary stricturoplasty, bilateral hepatojejunostomy, hepatic segmentectomy (lobectomy), and hepatolithotomy. Observation indicators: (1) surgical and postoperative situations; (2) typical case analysis; (3) follow-up. Follow-up using outpatient examination was performed to detect residual stones up to June 2019. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers.@*Results@#(1) Surgical and postoperative situations: 10 patients underwent RVS-guided surgeries successfully for complicated hepatolithiasis, with successful match in RVS (difference between CT images and ultrosound images <2 mm). No residual stone was identified by choledochoscope during operation. The operation time and volume of intraoperative blood loss were 285 minutes (range, 210-360 minutes) and 200 mL (range, 100-600 mL), respectively. No blood transfusion was needed during the operations. The duration of hospital stay was 20.5 days (range, 14.0-29.0 days). There was no perioperative death. One patient had postoperative biliary leakage and abdominal infection, and was cured after conservative treatment. (2) Typical case analysis: the tenth patient, female, 60 years old, was diagnosed with complicated hepatolithiasis, and was prepared to undergo hepatolithotomy+ quadrate lobectomy and hilar cholangioplasty+ bilateral hepatojejunostomy. Preoperative CT images and intraoperative color Doppler ultrasound images of the patient were fused and matched on the sagittal section of the portal vein and the cross section of the right branch of portal vein, and stones and important vessels were marked on the images. After accurate positioning, a curette was used to remove the stones. Removal of biliary stones through hepatic parenchyma and peripheral dilated bile ducts was conducted at the site where stones obviously existed. After the stones were removed, the intrahepatic bile duct and hilar bile duct merged. The left end of the bile duct split was confirmed by real-time ultrasound. After location of portal vein was determined by ultrasound, vascular plastic surgery was perfomed to avoid stenosis. (3) Follow-up: 10 patients were followed up for 6-12 months, with a median follow-up time of 8 months. One of 10 patients was suspected residual stones at the right peripheral hepatic anterior lobe by postoperative angiography at 2 months after surgery, and was not removed stones by choledochoscope. The patient had no recurrent symptoms after T-tube removal. The other 9 patients had no residual stones.@*Conclusion@#RVS applied in complicated hepatolithiasis is helpful for the precise intraoperative diagnosis, and the surgical treatment can be safe and effective.

The clinical data of 121 patients with chronic calcifying pancreatitis who were admitted to Hunan Provincial People′s Hospital from January 2015 to December 2019 were collected. There were 99 males and 22 females, aged from 10 to 78 years, with a median age of 43 years. The patients with type Ⅰ chronic calcifying pancreatitis underwent pancreaticoduodenectomy, duodenum-preserving pancreatic head total resection, or duodenum-preserving pancreatic head spoon-type resection respectively, and external drainage when combined with peripancreatic pseudocyst. Patients with type Ⅱ chronic calcifying pancreatitis underwent resection of pancreatic body and tail combined with splenectomy or dissection of pancreatic duct combined with pancreato-jejunum Roux-en-Y anastomosis. Patients with type Ⅲ chronic calcifying pancreatitis underwent pancreaticoduodenectomy or duodenum-preserving pancreatic head spoon-type resection, and external drainage when combined with peripancreatic pseudocyst. Patients with type Ⅳ chronic calcifying pancreatitis underwent basin-type internal drainage. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up using outpatient examination and telephone interview was performed to detect the recurrence of pain or chronic pancreatitis, the data of blood glucose, the morbidity of diabetes and diarrhea after surgery up to January 2020.

Two cases with postoperative grade A pancreatic fistula were cured after delaying the time of extubation. Four of the 49 patients with type Ⅲ pancreatic duct stone who underwent pancreaticoduodenectomy had the time to first anal flatus of (3.2±0.8)days, time to initial fluid diet intake of (4.1±1.2)days, and duration of hospital stay of (15.3±2.4)days, respectively. One case with postoperative grade A pancreatic fistula was cured after delaying the time of extubation without hemorrhage or biliary fistula. Forty-five of the 49 patients with type Ⅲ chronic calcifying pancreatitis who underwent duodenum-preserving pancreatic head spoon-type resection had the time to first anal flatus of (2.5±1.6)days, time to initial fluid diet intake of (2.8±0.9)days, and duration of hospital stay of (10.1±2.8)days, respectively. One case with postoperative anastomotic bleeding was cured after reoperation. One case with grade A pancreatic fistula was cured after delaying the time of extubation and 1 case with postoperative grade B pancreatic fistula was cured after puncture-duct-douch treatment. Sixteen patients with type Ⅳ chronic calcifying pancreatitis who underwent basin-type internal drainage had the time to first anal flatus of (2.6±0.7)days, time to initial fluid diet intake of (3.3±0.5)days, and duration of hospital stay of (10.4±3.0)days respectively. One case with intraperitoneal hemorrhage which represented as small amount of dark red liquid in the drainage tube of jejunum loop was cured after puncture-duct-douch treatment with noradrenaline sodium chloride solution. (3) Follow-up: Of the 121 patients, 113 (44 of type Ⅰ, 7 of type Ⅱ, 46 of type Ⅲ, 16 of type Ⅳ) were followed up for 3-58 months, with an average time of 34 months. During the follow-up, 13 patients (5 of type Ⅰ, 1 of type Ⅱ, 6 of type Ⅲ, 1 of type Ⅳ) had the recurrence of pain or pancreatitis, 55 patients (15 of type Ⅰ, 40 of type Ⅲ) with abdominal pain were improved significantly, and 45 patients (24 of type Ⅰ, 6 of type Ⅱ, 15 of type Ⅳ) did not have abdominal pain. Of the 37 patients (13 of type Ⅰ, 2 of type Ⅱ, 17 of type Ⅲ, 5 of type Ⅳ) with diabetes , 20 (6 of type Ⅰ, 2 of type Ⅱ, 12 of type Ⅲ) had blood glucose returned to normal and 17 (7 of type Ⅰ, 5 of type Ⅲ, 5 of type Ⅳ) needed controlling blood sugar with medicine. There were 5 patients (4 of type Ⅰ, 1 of type Ⅲ) diagnosed with diabetes and 3 patients (1 of type Ⅱ, 2 of type Ⅲ) with diarrhea postoperatively. Two patients of type Ⅲ chronic calcifying pancreatitis died, including 1 died of pancreatic cancer at 18 months after pancreaticoduodenectomy and 1 died of severe acute pancreatitis at 5 months after duodenum-preserving pancreatic head spoon-type resection.Conclusions:Chronic calcifying pancreatitis is a benign disease and should be treated to preserve functional tissues. Different surgical procedures should be adopted to treat different types of calcifying pancreatitis.

Objective To investigate the risk factors of postoperative hemorrhage after pancreatoduodenectomy (PD).Methods The retrospective case-control study was adopted.The clinical data of 857 patients with pancreatic diseases who were admitted to the First Affiliated Hospital of Hunan Normal University from January 2007 to December 2014 were collected.All the 857 patients underwent PD and digestive tract reconstruction using the Child method.The number of patients with postoperative hemorrhage,classification,bleeding sites,source and time of bleeding and method and effect of treatment after PD were observed.The correlations among the gender,age,concomitant diseases (diabetes and hypertension),malignancy degree of tumor,the preoperative levels of serum alanine transaminase (ALT),total bilirubin (TBil),albumin (Alb) and prothrombin time (PT),international normalized ratio (INR),operation time,volume of intraoperative blood loss,method of pancreatic and jejunal anastomosis and postoperative hemorrhage after PD were analyzed.The follow-up of outpatient examination and telephone interview was performed to observe postoperative recovery of patients for 2 months till February 2015.Univariate analysis and multivariate analysis were done using the chisquare test and Logistic regression model,respectively.Results Of 72 patients with postoperative hemorrhage,grade A,B and C hemorrhage were detected in 3,41 and 28 patients,respectively,and 41,29 and 2 patients had respectively enteral hemorrhage,parenteral hemorrhage and enteral and parenteral hemorrhage.After PD,38 patients had hemorrhage located at the gastrointestinal tract,9 at the common hepatic artery,proper hepatic artery and gastroduodenal artery (5 due to pseudoaneurysm),5 at the pancreatic section,3 at the jejunal mesenteric vessels,2 at the middle colic arterial branches,1 at the superior mesenteric artery,1 at the superior mesenteric vein and 13 at the ambiguous bleeding sites.The early and late stage hemorrhages (within postoperative hour 24 and after postoperative hour 24) were detected in 20 and 52 patients,respectively.Of 44 patients with grade A and B of hemorrhages,17 underwent conservative treatment,16 underwent reoperation,8 underwent hemostatic therapy under gastroscopy,3 underwent interventional treatment.All the 44 patients had good hemostasis effect.Of 28 patients with grade C of hemorrhage,interventional treatment,reoperation,hemostatic therapy under gastroscopy,conservative treatment,interventional treatment + reoperation and gastroscopy + interventional treatment were applied to 10,7,4,3,3 and 1 patients,respectively.Ten of 28 patients died and 18 had successful hemostasis.The gender and preoperative levels of ALT and TBil were related factors affecting postoperative hemorrhage after PD in the univariate analysis (x2 =4.516,7.585,7.209,P ＜ 0.05).Male,preoperative ALT ≥ 172 U/L and preoperative TBil ≥ 159 μmol/L were the independent risk factors affecting postoperative hemorrhage after PD in the multivariate analysis (HR =2.033,1.860,1.872,95％ confidence interval:1.237-3.341,1.135-3.047,1.060-3.307,P ＜ 0.05).Fifty of 62 patients were followed up for a median time of 2 months with a follow-up rate of 80.6％ (50/62),and no rehemorrhage was occurred.Conclusion Male,preoperative ALT≥172 U/L and preoperative TBil≥≥ 159 μmol/L are the independent risk factors affecting postoperative hemorrhage after PD.
ABSTRACT
Objective To investigate the efficacy of duodenum-preserving pancreatic head resection (DPPHR) for the treatment of chronic pancreatitis combined with type Ⅰ and Ⅲ pancreatic duct stones.Methods The clinical data of 55 patients with chronic pancreatitis and type Ⅰ and Ⅲ pancreatic duct stones who were admitted to the People's Hospital of Hunan Province from June 2008 to June 2013 were prospectively analyzed.All the patients were randomly divided into the pancreatoduodenectomy (PD) group (27 patients) and the DPPHR group (28 patients).There were 18 patients with chronic pancreatitis and type Ⅰ pancreatic duct stones and 9 patients with chronic pancreatitis and type Ⅲ pancreatic duct stones in the PD group.There were 16 patients with chronic pancreatitis and type Ⅰ pancreatic duct stones and 12 patients with chronic pancreatitis and type Ⅲ pancreatic duct stones in the DPPHR group.Patients in the PD group received PD + Child anastomosis + end-toside pancreato jejunal anastomosis + pancreatic stent placement + end-to-side cholangiojejunostomy.Patients in the DPPHR group received free of duodenum + pancreatic duct incision + resection of pancreas at 1 cm ahead of the pancreatic duct + extraction of the pancreatic duct stones + pancreaticoduodenal Roux-en-Y anastomosis.Patients were followed up via out-patient examination till December 2013.The measurement data were analyzed using the t test or Mann-Whitney U test,and the count data were analyzed using the chi-square test.Results During the operation,2 patients in the PD group were converted to the DPPHR group and 1 patient in the DPPHR group was converted to the PD group.No patient died during the perioperative period,and the symptoms including abdominal pain and diarrhea were alleviated at postoperative week 2.The operation time,blood loss,duration of postoperative hospital stay,total expenses and incidence of complications were (7.5 ± 1.6) hours,(460 ± 88) mL,(18.0 ± 3.5) days,(7.8 ± 2.1) × 104 yuan,19.2％ (5/26) in the PD group,and (4.0 ± 1.0) hours,(120 ± 36) mL,(9.5 ± 2.9) days,(3.9 ± 1.2) × 104 yuan,3.4％ (1/29) in the DPPHR group,there were no significant differences in the operation time,blood loss,duration of hospital stay,total expenses and incidence of complications between the 2 groups (t =9.358,11.365,6.325,8.647,x2 =3.976,P ＜ 0.05).Fifty-three patients were followed up,with the median time of 33 months (range,6 months to 5 years).No patient died during the follow-up.Twenty-four patients in the PD group were followed up,2 patients had slight abdominal pain,1 patient had severe abdominal pain due to pancreatic duct stenosis,and the symptom was alleviated after resection of partial pancreas ; the condition of 12 patients was improved among the 19 patients with diabetes.Twenty-nine patients in the DPPHR group were followed up,2 patients had slight pain; the condition of 16 patients were improved among the 22 patients with diabetes.Conclusion DPPHR is an ideal surgical procedure for patients with chronic pancreatitis and type Ⅰ and Ⅲ pancreatic duct stones.
