Covered stent treatment for arterial complications after pancreatic surgery: risk assessment for recurrence and peri-stent implantation management. Eur Radiol 2023; 33:1779-1791. [PMID: 36149482 PMCID: PMC9510453 DOI: 10.1007/s00330-022-09134-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 07/07/2022] [Accepted: 08/29/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVES To explore the risk factors for recurrence of arterial complications after pancreatectomy during the period of covered stent implantation and to provide some opinions on peri-stent implantation management. METHODS Data on patients implanted with covered stents due to arterial complications after pancreatectomy between January 2017 and December 2021 were analyzed retrospectively. Technical success, clinical success, recurrence, and survival were evaluated to elucidate the practicability of covered stents. Wilson score, Random Forest, logistic regression, and Pearson's chi-square test with bootstrap aggregation were performed for determining the perioperative risk factors for recurrence. RESULTS Among all fifty-five patients, success stent implantation (technical success) was achieved 100%. Patients who were hemodynamically stabilized without further treatment for artery complications in situ (clinical success) accounted for 89.1%. Based on statistical analysis, pre-stent implantation pancreatic fistula was identified as a robust recurrence-related risk factor for preoperative assessment (p = 0.02, OR = 4.5, 95% CI [1.2, 16.9]; pbootstrap = 0.02). Post-stent implantation pancreatic fistula (p = 0.01, OR 4.5, 95% CI [1.4, 14.6]; pbootstrap < 0.05) and SMA branches or GDA stumps (p = 0.02, OR 3.4, 95% CI [1.1, 10.3]) were relevant to recurrence. The survival rate during hospitalization was 87.3%. All survivors were free from recurrence during the subsequent follow-up. Vasospasm and stent occlusion were observed as short-term and long-term complications, respectively. CONCLUSION A covered stent implantation is a feasible and effective treatment option for post-pancreatectomy arterial complications. Rigorous management of pancreatic fistula, timely detection of problems, sensible strategies during stent implantation, and reasonable anticoagulation therapy are necessary for a better prognosis. KEY POINTS • A covered stent is feasible for various artery-related complications after pancreatectomy and has an ideal therapeutic effect. • Pancreatic fistula during the perioperative period of the covered stent is an independent risk factor for recurrent arterial complications and SMA branches or GDA stumps are prone to be recurrent offending arteries. • Rigorous management of pancreatic fistula, timely detection of problems, sensible strategies during stent implantation, and reasonable anticoagulation therapy are necessary for a better prognosis.

Oncological outcomes of open, laparoscopic and robotic colectomy in patients with transverse colon cancer. Tech Coloproctol 2022; 26:821-830. [PMID: 35804251 DOI: 10.1007/s10151-022-02650-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 05/25/2022] [Indexed: 10/17/2022]
Abstract
BACKGROUND Literature concerning surgical management of transverse colon cancer is scarce, since many key trials excluded transverse colon cancer. The aim of this study was to evaluate clinical and oncological outcomes comparing open, laparoscopic and robotic transverse colon cancer resection. METHODS Consecutive patients who underwent elective surgery for transverse colon cancer between December 2005 and July 2021 were included. Data were kept in a prospective database approved by the institutional ethics committee. Primary outcome was overall and disease-free survival. Secondary outcomes included complications, operative time, length of stay and lymph node harvest. Statistical analysis was corrected for age and tumour localisation. RESULTS Two hundred and forty-six (38 robotic, 71 open and 137 laparoscopic resections) were recruited in this study. There were five conversions during laparoscopic procedures. Operative time was significantly shorter in robotic vs laparoscopic procedures (195 vs 238 min, p = 0.005) and length of stay was shorter in robotic vs laparoscopic and open group (7 vs 9 vs 15 days, p < 0.001). There was no difference in overall complications. R0 resections were similar. Lymph node harvest was highest in the robotic group vs. laparoscopic or open (32 vs. 29 vs. 21, p < 0.001). Overall survival was 97%, 85% and 60% (p < 0.001) and disease-free survival was 91%, 78% and 56% (p < 0.001) for the robotic, laparoscopic and open groups, respectively. CONCLUSIONS Minimally invasive surgery for transverse colon cancer is safe and offers good clinical and oncological outcomes. Robotic resection is associated with significantly shorter operating times, higher lymph node harvest, lower conversion rate and does not increase morbidity. Differences in disease-free and overall survival should be further explored in randomised controlled trials.

Efficacy of the slow firing method using a reinforced triple-row stapler for preventing postoperative pancreatic fistula during laparoscopic distal pancreatectomy. Surg Today 2021; 52:260-267. [PMID: 34322726 DOI: 10.1007/s00595-021-02344-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 05/07/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE Postoperative pancreatic fistula (POPF) remains the most clinically relevant complication of laparoscopic distal pancreatectomy (LDP). The present study evaluated the efficacy of the "slow firing method" using a reinforced triple-row stapler (Covidien, Tokyo, Japan) during LDP. METHODS This retrospective single-center study included 73 consecutive patients who underwent LDP using the slow firing method. A black cartridge was used in all patients. The primary endpoint was the rate of clinically relevant POPF (CR-POPF) after LDP. Secondary endpoints included perioperative outcomes and factors associated with CR-POPF as well as the correlation between the transection time and thickness of the pancreas. RESULTS Four patients (5.5%) developed CR-POPF (grade B). Overall morbidity rates, defined as grade ≥ II and ≥ III according to the Clavien-Dindo classification, were 21 and 11%, respectively. The median postoperative hospital stay was 10 days. Preoperative diabetes (13.6 vs. 0.2%, P = 0.044) and thickness of the pancreas ≥ 15 mm (13.8% vs. 0%, P = 0.006) were identified as independent risk factors for CR-POPF. The median transection time was 16 (8-29) min. CONCLUSION The slow firing method using a reinforced triple-row stapler for pancreatic transection is simple, safe, and effective for preventing CR-POPF after LDP.
