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 summarize our clinical experience and management of an anomalous proximal bile duct joining the cystic duct in laparoscopic cholecystectomy (LC).@*Methods@#A retrospective study was conducted on 8 patients who had an anomalous right anterior bile duct joining the cystic duct who were treated at the Hunan Provincial People's Hospital from March 2003 to January 2019.@*Results@#All the 8 patients were diagnosed to have gallstones cholecystitis on preoperative CT, MRI and abdominal ultrasound. There were no suggestions of an anomalous bile duct. A total of 6 patients underwent reoperation after LC due to abdominal pain and biliary peritonitis. These 6 patients were treated with drainage and T-tube insertion. In the other 2 patients, the anomalous bile duct opening which joined the cystic duct were detected during LC. There was one patient converted to open laparotomy with preservation of the cystic duct and underwent common bile duct T-tube drainage. The other patients continued with laparoscopic surgery. The cystic duct was partially resected with removal of gallbladder, followed by common bile duct drainage. The average follow-up period was 3.4 years and the results were satisfactory.@*Conclusions@#Biliary duct anomaly is the main cause of iatrogenic proximal bile duct injury during laparoscopic cholecystectomy. It is not uncommon to have the anomaly of insertion of right anterior segmental bile duct to the cystic duct. To avoid iatrogenic biliary tract injury, careful preoperative study of X-ray films, accurate identification of the intraoperative gallbladder triangle anatomical structures. Strict adherence to carry out the three-word procedure of " discrimination, cut, identify" will help to reduce the incidence of biliary tract complications in laparoscopic cholecystectomy.

ABSTRACT

Objective@#To summarized the experience in laparoscopic duodenum-preserving pancreatic head resection (LDPPHR).@*Methods@#The clinical data of four patients who underwent LDPPHR from February 2017 to June 2018 in Hunan Provincial People’s Hospital were retrospectively analyzed. The Clinical characteristics, operation time, intraoperative blood loss, biliary fistula rate, pancreatic fistula rate and follow-up data were analyzed.@*Results@#The four patients included one patient with a solid pseudopapillary tumor and three patients with a serous cystadenoma. Two patients underwent duodenum-preserving total pancreatic head resection, and two patients underwent duodenum-preserving subtotal pancreatic head resection. The operation time of the four patients was (525.8±121.8) minutes, and the blood loss (250.0±191.5) ml. Biliary duct drainage was carried out in 2 patients: one patient developed biochemical bile leakage, while another had no postoperative complication. The two patients without biliary drainage developed grade B pancreatic leakage, delayed bile leakage, abdominal bleeding and infection. All the three patients who developed postoperative complications were treated conservatively and they recovered well.@*Conclusions@#LDPPHR was designed to better preserve the integrity and function of digestive tract. However, the perioperative complications were high. This operation should only be carried out in large pancreatic centers. Routine biliary drainage is recommended to surgeons with little experience in this operation.

ABSTRACT

Objective To explore the expressions of cyclooxygenase-2 (COX-2), phosphatase and tensin homolog deleted on chromosome ten (PTEN) in hepatobiliary calculus associated with cholangiocarcinoma (HCWC) and their clinical significance. The relationship between the expressions of COX-2, PTEN and the onset and progression of HCWC was investigated to form an experimental base for the prevention and treatment of HCWC. Methods Thirty seven patients with tumor tissues of HCWC (group C), thirty patients with tissues of bile duct surrounding intrahepatic calculus (group B), and ten patients with normal tissues of bile duct from operations of hemangiomas of liver or liver trauma as the control (group A) were sampled and collected. A two-step immunohistochemistry (SP method) was employed to detect and statistically analyze the expressions of COX-2 and PTEN in each of the 3 groups. Results In groups A, B, C, the positive rate of the expression of COX-2 was 10%,33.3%, and 70.3%, respectively. The positive rates of expression of COX-2 in the carcinoma tissues of HCWC was significantly higher compared with the control group (P<0. 01). In groups A, B, C the positive rates of the expression of PTEN was 90. 0%, 80. 0%, and 35.0%, respectively. The positive rate of expression of PTEN in the carcinoma tissues of HCWC was significantly lower than the control group (P<0. 01). The expression of COX-2 was followed by a low expression of PTEN in the tissues of HCWC. Kendall's related analysis showed a strong negative correlation between the expression of COX-2 and PTEN in HCWC (r=-0. 323, P<0. 05). Conclusions A high expression of COX-2 was related to HCWC. There was a negative correlation between the expressions of COX-2 and PTEN in HCWC. A high expression of COX-2 and a low expression of PTEN suggested a high chance of HCWC in extrahepatic or lymphatic metastasis.

ABSTRACT

Objective To investigate the effect of c-myc ASODN on the proliferation and invasion of human bile duct carcinoma cell line QBC939. Methods QBC939 cells was conventionally cultured. C-myc ASODN was designed and transfected into QBC939 cell line. MTT assay and transwell experiment were used to study cell proliferation and invasion of QBC939 cells. Results MTT assay showed that cell survival rate in ASODN group was significantly lower than that in blank group(P < 0.05). Transwell experiment showed that the num-ber of cells penetrated in ASODN group was significantly lower than that in blank group(P<0.01). The cell survival rate and the number of cells penetrated in vechicle group had no difference with blank comparison group(P>0.05). Conclusions C- myc ASODN can inhibit the proliferation and invasion of QBC939 cells.

ABSTRACT

Objective To study the experience in prevention and treatment of iatrogenic bile duct trauma(IBDT). Methods A retrospective study was made on the clinical data of 118 patients with iatrogenic bile  duct trauma admitted to the Hunan Provincial People's Hospital from March 1990 to September 2000. Results 50.8% (60/118) of patients with IBDT resulted from the wrong identification of the anatomy of the Calot' Triangle during cholecystectomy. The clinical diagnosis of IBDT depended on the clinical findings, diagnostic abdominocentesis and image examination. The diagnostic rate of ultrasonography for IBDT was 93.2%(110/118). According to the injury site of bile duct, IBDT could be divided into 6 types, the most common type of  IBDT was resection of partical hepatic duct and part common bile duct(type Ⅲ) which occurred in 83.9% (99/118) of the patients. The cure rate of IBCT was 100%(118/118) in this series due to the choice of operation according to the trauma type. Conclusions The key of prevention to IBDT lies in abiding by the princible of “identifying-cut-recognazing” during cholecystectomy. The choice for surgical operative procedure should agree with the trauma type.

ABSTRACT

Objective To investigate the application of selective hepatopetal blood occlusion techniques in anatomic hepatectomy.Methods We retrospectively reviewed the clinical data of 259 patients with hepatolithiasis or liver tumor undergoing anatomic hepatectomy under selective hepatopetal blood occlusion from January 2006 to December 2009.Results Totally,183 cases with hepatolithiasis and 76 cases with liver tumor underwent anatomic hepatectomy under selective hepatopetal blood occlusion.The average intra-operation blood loss was 210 mL(120-1 600 mL);post-operation incidence of complications and the rate of residual stones was 10.9% and 4.2%,respectively.Thre was no operative death in this series.The intrahepatic recurrence and metastasis rate of liver tumor was 23.6% and the median recurrence was 16.3 months.Conclusions The use of a appropriate selective hepatopetal blood occlusion during anatomic hepatectomy for hepatolithiasis and liver tumors is an effective measure to reduce surgical complications and improve outcome.

ABSTRACT

Objective To study the operative procedure for stage III and IV hilar cholangiocarcinoma. Methods A crescent shape excision on the edges of multiple hepatic segments followed by a 'skirt edge′ form hepatoenterostomy to drain the multiple hepatic ducts was used to treat unresectable stage III,IV hilar cholangiocarcinoma, . Results (1)the mean survival time was 15.65 months;(2)the patient comfortable index was 81.5%;(4)there was no operative death in the series. Conclusions The 'skirt edge' form hepatoenterostomy is a feasible and effective palliative method for unresectable stage III,IV cholangiocarcinoma.
