ABSTRACT
Objective To observe the clinical effect of percutaneous transhepatic one-step biliary fistulation (PTOBF) and percutaneous transhepatic cholangioscopy (PTCS) in the treatment of hepatolithiasis with hepatobiliary surgery history,and to explore the clinical application value of PTOBF.Methods This is retrospective analysis of 68 patients with hepatolithiasis who were admitted to hepatobiliary surgery in the First Affiliated Hospital of Guangzhou Medical University from November 2009 to October 2017.Among these cases,35 patients in the observation group (group PTOBF) were treated with PTOBF,and 33 patients in the control group (group PTCS) received PTCS treatment.The final clearance rate,the postoperative complications rate,the hospitalization time,the operation times within the course of treatment,the recurrence rate and the residual stenosis rate of the two groups were compared.Results Compared with group PTCS,the clearance rate was significantly higher in group PTOBF(82.9％ vs 54.6％,P＜0.05),while the postoperative complications rate between the two groups are similar (14.3 ％ vs 30.3 ％,P＞ 0.05);Besides,the hospitalization time(12.3±5.3 d vs 17.4±7.0 d,P＜0.05),the operation times within the course of treatment (2.2±1.3 vs 2.8±1.0,P＜0.05) and the recurrence rate(17.4％ vs 39.4％,P＜0.05) of group PTOBF were obviously lower.Conclusions PTOBF is a safe and feasible treatment for hepatolithiasis with hepatobiliary surgery history.Compared with PTCS,it has the advantages of short hospitalization time,fewer operations and better recovery.
ABSTRACT
Objective To evaluate the clinical value of percutaneous transhepaticcholangioscopic lithotomy (PTCSL)combined with rigid cholangioscopy in treatment of recurrent hepatolithiasis. Methods Retrospective analysisof therapeutic result of 54 patientswith postoperative recurrent hepatolithiasisduring January 2012 to January 2015. Twenty eight cases were recruited as the observation group (PTCSL group). Twenty six cases were recruited as the control group (Laparotomy group). Following parameters were observed, operation time, intraoperative blood loss, clearance of stones and postoperative hospital stay. Results The operation time, intraoperative blood loss , clearanceof stones , and the postoperative hospital stay of the PTCSL group werebetter than that of the laparotomy group (P<0.05). The number of patients with postoperative pain of the PTCSL group was significantly lower than in the laparotomygroup (P<0.05). There were no significant differences in other complication rates. There was no difference in terms of stone recurrence , incidence of cholangitis and intrahepatic biliary strictures recurrence ratebetween two groups in follow-up period. Conclusions PTCSL combined with rigid choledochoscopywas a safe and effectivemethod with minimal invasion formanagement of the postoperative recurrent hepatolithiasis. It could got a better resultsin the short-term outcomes.
ABSTRACT
With the developments of digital medicine, Gd-EOB-DTPA enhanced magnetic resonance imaging, molecular imaging and optical/acoustic multi-modality imaging, the hepatopancreatobiliary surgery have entered the era of precise diagnosis and treatment.Bidimensional pattern of disease diagnosis and treatment is developing toward three-dimensional pattern, which make the diagnosis and treatment more comprehensive and clear.Morphological imaging is gradually developing towards molecular imaging.Ultimately, the goal of truly precise diagnosis and accurate treatment will be achieved.
ABSTRACT
Objective To explore the effect of LPLD (laparoscopic peritoneal lavage and drainage ) on SAP (severe acute pancreatitis), and to compare its effect with that of non- LPLD (conservative medical management). Methods We collected data from 87 consecutive patients with SAP, from January 2009 to May 2014, including LPLD group (n = 46) and non-LPLD group (n = 41). LPLD was performed in the 1st and 2nd week after the disease onset in LPDP group and other treatment in LPDP group was the same as that in non-LPLD group. Data were comparatively analyzed in two groups about the length of hospital stay, ICU stay, cure rate, incidence of complications and in-hospital mortality. Results In LPLD group, hospital stay, and ICU stay were shorter while cure rate was higher than those in non-LPLD group , and the difference was statistically significant (P 0.05). Conclusion Compared with non-LPLD, LPLD is effective in short outcome, which is a promising treatment for SAP.
ABSTRACT
<p><b>OBJECTIVE</b>To study the value of three-dimensional (3D) visualization, 3D printing and 3D laparoscopy (3-3D techniques) in the diagnosis and surgical treatment of hepatic tumors.</p><p><b>METHODS</b>From November 2013 to January 2015, 22 patients with hepatic tumors admitted in our department underwent abdominal thin-slice CT scanning. The CT images were imported into Medical Image three Dimensional Visualization System (MI-3DVS) for 3D reconstruction. Standard Template Library (STL) files were exported for 3D printing. The hepatic vascular classification and predicted liver resection were performed with the aid of MI-3DVS system. The 3D models were then printed and virtual liver resections were executed accordingly. Based on these preoperative surgical planning data, we performed anatomical hepatectomy using 3D laparoscopy, and the intraoperative blood loss, volume of virtual and actual liver resection and postoperative hospital stay were recorded.</p><p><b>RESULTS</b>According to Michels's classifications, 19 patients had type I, 2 had type II, and 1 had type VIII hepatic arteries; based on Cheng classifications, the portal vein was classified into type I in 17 cases, type II in 2 cases, and type III in 2 cases, and type IV in 1 case; according to Nakamura classifications, the right hemiliver hepatic vein was classified into type I in 10 cases, type II in 7 cases, and type III in 5 cases. In the virtual operations, the mean volume of liver resected was 490 ± 228 ml and the mean remnant liver volume was 885 ± 139 ml, with a remnant to functional liver volume ratio of (71 ± 11)%. The 3D printed models stereoscopically displayed the location of the liver tumors and adjacent liver vascular structure clearly. Laparoscopic hepatectomy was performed successfully in 20 patients guided by the 3-3D techniques, and the other 2 patients required convertion to open hepatectomy. The mean operation time was 186 ± 92 min, the intraoperative blood loss was 284 ± 286 ml, the mean actual liver resection volume was 491 ± 192 ml, and the mean postoperative hospital stay of the patients was 8.6 ± 3.7 days.</p><p><b>CONCLUSIONS</b>The 3-3D technique can facilitate the evaluation of preoperative risk and critical anatomical structures and navigate the surgical procedure in real time in anatomical hepatectomy for hepatic tumors.</p>
