  • Implanting Uncovered SelfExpandable Metal Stent Through Endoscope for Management of Distal Malignant Biliary Obstruction

    Objective To investigate the effect of implanting uncovered self-expandable metal stent for treatment of distal malignant biliary obstruction through endoscope. Methods The effect of therapy about implanting uncovered self-expandable metal stents to 16 patients who had unsectable malignant tumors companing with obstructive jaundice through endoscope was reviewed. Results Fifteen of the studied patients were implanted uncovered self-expandable metal stents successfully (94%), for their internal drainage were patent. At the seventh and fourteenth day after implantation, liver function and B-ultrasound were rechecked. Compared to the data before operation, total bilirubin, direct bilirubin and transaminase declined respectively (P<0.01). And the diameter of the total biliary duct became shorter (P<0.01). Six of them returned to the normal level in three weeks. Early adverse events (in seven days) included mild acute pancreatitis (one case) and acute cholangitis (one case). Mean survival and patency of drainage were 186.93 days (54 to 426 days) and 156 days (51 to 426 days) respectively. All of them, 3 cases occured obstruction of stents (20%). Conclusion Implantation of uncovered selfexpandable metal stent through endoscope is an ideal therapy for distal malignant biliary obstruction.

  • Efficacy of Endoscopic Bilateral Biliary Metal Stent Placement for Malignant Hilar Biliary Obstruction

    Objective To evaluate the safety and efficacy of simultaneous endoscopic bilateral placement of selfexpandable metal biliary stents in malignant hilar biliary obstruction. MethodFrom May 2007 to December 2010, a total of 24 patients with hilar malignancy of Bismuth type Ⅱ to Ⅳ underwent endoscopic retrograde cholangiopancreatography (ERCP) and bilateral metal stent placement. Technical success rate, functional success rate, ERCP related complications, stents’ patency time, and patient’ survival time were recorded and reviewed. Results Twentyone of 24 patients were followedup for average 39 months. Technical success rate was 100%, the average operation time was (36.2±13.9) min, the functional success rate was 95.45%. Mild cholangitis occurred in 2 cases and there was no ERCP related pancreatitis, bleeding, perforation, and death. Stents dysfunction occurred in 7 within followup period. Amonge them, plastic stents were inserted through the metallic stents in 4 cases, PTCD was required in 1 case, and conservative therapy was given in the other 2 cases. The median stent’ patency time and median patient’ survival time were 253 d (95% CI: 199.79-306.21) and 229 (95% CI : 154.53-303.47), respectively, with no significant differences between Bismuth classification types. ConclusionEndoscopic simultaneous bilateral biliary metal stent placement is technically feasible, safe, and effective to malignant hilar obstruction.

  • Fully covered self-expandable mental stent in treatment of biliary stricture after liver transplantation

    Objective To evaluate safety and long-term efficacy of fully covered self-expandable mental stent (FCSEMS) in treatment of biliary stricture after liver transplantation (LT). Methods From January 2010 to June 2018, the data of patients with the biliary stricture after the LT underwent the endoscopic retrograde cholangiagraphy (ERCP) at the First Hospital of Lanzhou University were collected retrospectively. The therapeutic effect of the FCSEMS was evaluated. Results A total of 21 patients with the biliary stricture after the LT were treated. The success rate of the stent placement was 100%. The FCSEMSs were used in 7 cases and the only multiple plastic stents (MPSs) were used in 14 cases. There were no significant differences in the gender, age, time of biliary stricture, frequency of ERCP, recurrence time of biliary stricture, cure time of biliary stricture, curative effect, recurrence of biliary stricture, and incidence of complications between the patients treated with the FCSEMS and the MPS (P>0.050), but the number of plastic stents in the patients treated with the FCSEMS was significantly less than that in the patients treated only with the plastic stents (P<0.050), while the duration of stent retention was longer than that in the patients treated only with the plastic stents (P<0.050). Six patients were cured, 1 was remitted, and 2 were relapsed by the FCSEMS. Eight were cured, 3 were remitted, 3 were ineffective, and 5 were relapsed by the MPS alone. Conclusions FCSEMS might be an safe effective alternative to plastic stent in treatment of biliary stricture after LT, resulting in a longer duration placement, less number of plastic stent use. It is necessary to further accumulate cases to validate cure rate and recurrence rate of biliary stricture.

  • Comparative study of emergency surgery versus self-expanding metal stent in treatment of malignant left-sided colonic obstruction

    ObjectiveTo compare the short- and long-term effects of emergency surgery (ES) and self-expanding metal stent (SEMS) in treatment of malignant left-sided colonic obstruction.MethodsThe patients with malignant left-sided colonic obstruction who met the inclusion and exclusion criteria in the Third Affiliated Hospital of Soochow University from October 2010 to October 2020 were retrospectively collected and divided into ES group (n=43) and SEMS group (n=22). The baseline data, surgical data, postoperative data, and prognosis (overall survival and relapse free survival) were compared, and the risk factors of tumor recurrence after surgery were further analyzed by Cox proportional hazards regression model. ResultsIn this study, 65 cases of malignant left-sided colonic obstruction were included, including 43 cases in the ES group and 22 cases in the SEMS group. There were no statistical differences in the baseline data of the two groups (P>0.05). There were no significant differences in the incidence of postoperative complications [13.6% (3/22) vs. 23.3% (10/43), P=0.555], recurrence rate [40.9% (9/22) vs. 37.2% (16/43), P=0.772], and rate of receiving postoperative chemotherapy [68.2% (15/22) vs. 48.8% (21/43), P=0.138] between the SEMS group and ES group. Compared with the ES group, although the median hospitalization time was longer (20 d vs. 12 d, P=0.001), and the median hospitalization cost was higher (65 033 yuan vs. 40 045 yuan, P=0.001), the stoma rate of the SEMS group was lower [36.4% (8/22) vs. 88.4% (38/43), P=0.001], and the minimally invasive (laparoscopic) rate was higher [36.4% (8/22) vs. 7.0% (3/43), P=0.008]. There were no significant differences in the 4-year cumulative overall survival (46.9% vs. 48.4%, P=0.333) and 4-year cumulative relapse free survival (36.2% vs. 44.8%, P=0.724) between the SEMS group and ES group, but the overall survival of the SEMS group was better than that of the ES group for the patients with stage Ⅲ–Ⅳ (χ2=4.644, P=0.047). Multivariate analysis of Cox proportional hazards regression model showed that increased TNM stage increased the risk of postoperative tumor recurrence of patients with malignant left-sided colonic obstruction [HR=2.092, 95%CI (1.261, 3.469), P=0.004]. ConclusionsShort- and long-term effects of ES and SEMS in treatment of malignant left-sided colonic obstruction are equivalent. Although SEMS mode has a longer hospital stay and higher hospitalization costs, stoma rate is lower and laparoscopic surgery rate is higher. Overall survival of SEMS mode in treatment malignant left-sided colonic obstruction patients with stage Ⅲ–Ⅳ is better.

  • Treatment strategy for the obstructive or perforated rectal cancer

    Colorectal cancer is one of the common malignant tumor in the world, and about 57.6% of colorectal cancer surgical cases in our country are rectal cancer patients, which occupies a major proportion. Some patients with rectal cancer may already have emergencies such as intestinal obstruction or limited perforation at the time of consultation, which require immediate relevant treatment measures. Currently, there are multiple surgical and endoscopic treatment strategies available for obstructive and perforated rectal cancer. Surgeons need to perform an accurate and comprehensive assessment of the disease, define the goals of the current treatment, and formulate an appropriate treatment plan based on the patient’s clinical and oncological status in order to optimize the patient’s oncological outcome while minimizing the risk of complications associated with emergency colorectal surgery.
