A new simplified one-port laparoscopic technique for peritoneal dialysis catheter placement

Suture passer combined with two-hole laparoscopic peritoneal dialysis catheterization in patients undergoing peritoneal dialysis

BACKGROUND

Laparoscopic techniques are being widely applied for peritoneal dialysis (PD) catheter (PDC) placement. The suture passer is a novel fixation tool that aims to reduce catheter migration. We compared the clinical value of the suture passer combined with two-hole laparoscopic PDC placement to open surgical placement by evaluating preoperative and postoperative conditions, as well as the onset of complications in both groups.

METHODS

A retrospective study was conducted including 169 patients who underwent PDC placement surgery from January 2021 to May 2023. Based on the method employed, patients were divided into two groups: the suture passer combined with a two-hole laparoscopy group (SLG) and the open surgical group (SG). Comprehensive patient information, including general data, preoperative and postoperative indicators, peritoneal function after surgery, and the incidence rate of complications, were collected and analyzed.

RESULTS

The SLG showed a statistically significant decrease in operative time, intraoperative blood loss, and 6-month postoperative drift rate compared to the SG (p < 0.05). No statistically significant differences were observed between the two groups in terms of sex, age, primary disease, hospitalization time, hospitalization costs, preoperative and postoperative examination indicators, peritonitis, and omental wrapping.

CONCLUSIONS

Suture passer combined with two-hole laparoscopic PDC placement, characterized by simplicity and facilitating secure catheter fixation, was deemed safe and effective for patients undergoing PD. It reduces the catheter migration rate and improved surgical comfort. Overall, this technique demonstrates favorable outcomes in clinical practice.

Modified laparoscopic placement of peritoneal dialysis catheter with intra-abdominal fixation

PURPOSE

Peritoneal dialysis (PD) is a commonly accepted method of treating end-stage renal disease (ESRD). Various laparoscopic techniques for the placement of PD catheter have been described. In this study, we developed a novel modified laparoscopic technique for PD catheter placement and evaluated the early results.

METHODS

A straight Tenckhoff PD catheter was placed employing the modified technique in 39 consecutive patients with ESRD from May 2013 to April 2016. The technique is laparoscopically guided intra-abdominal fixation of the PD catheter tip at one point by using suture passer hernia forceps. Individual information including sex, age, primary disease etiology, complications, surgical duration, morbidity, mortality and catheter survival was collected and analyzed.

RESULTS

The modified laparoscopic procedure was effectively performed in all patients with a mean operative time of 45 ± 7 min. No conversions from laparoscopy to open surgery of catheter placement occurred. There was one case showing early pericatheter leakage. There were no serious complications, such as bleeding, abdominal wall hernias, distal catheter cuff extrusion and infections of the exit site or tunnel during surgery or the postoperative duration. No mortality was observed in this group of patients. The 6-month follow-up study showed 100% catheter-related complication-free survival.

CONCLUSIONS

Our modified laparoscopic intra-abdominal fixation technique using suture passer hernia forceps is a simple and safe method for PD catheter placement and is effective in minimizing the risk of catheter migration.

Long-Term Outcomes of Single-Port Laparoscopic Placement of Peritoneal Dialysis Catheter

INTRODUCTION

Laparoscopic insertion of peritoneal dialysis (PD) catheter has become a preferred method compared to the traditional open technique for PD catheter insertion. We retrospectively report the outcome of 1-port laparoscopic placement PD catheters in our institution.

METHODS

A total of 263 patients with end-stage renal disease who underwent single-trocar laparoscopic PD catheter insertion during a recent 6-year period were reviewed. Laparoscopic technique involves introducing a PD catheter over a stiff guidewire into the abdominal cavity through a 10-mm laparoscopic port. Pertinent clinical variables, procedural complications, and follow-up outcome were analyzed.

RESULTS

There were 182 men and 81 women. The mean age was 56 years. Technical success was 95.8%. Catheter occlusion was the most common early complications (<6 months) that occurred in 4 (1.5%) patients. Late complications (> 6 months) including catheter occlusion, cuff extrusion, catheter leakage, catheter migration, infection, and hernia occurred in 5 patients (1.9%), 2 patients (0.8%), 3 patients (1.1%), 3 patients (1.1%), 6 patients (2.3%), and 4 patients (1.5), respectively. Mean follow-up time was 39 ± 18 months. Catheter survival rate at 1, 2, 3, 4, and 5 years was 96%, 94%, 90%, 85%, and 82%, respectively.

CONCLUSION

Laparoscopic PD catheter implantation via a single-trocar utilizing a stiff guidewire technique is feasible and safe. This method can result in low complication and high catheter survival rate.

Treatment of necrotizing acute pancreatitis with peritoneal lavage and dialysis by a new simplified technique insert catheters: One retrospective study

Peritoneal lavage and dialysis is an approach to treat necrotizing acute pancreatitis as it removes dialyzable toxins and reduces severe metabolic disturbances. Successful catheter implantation is important for delivering adequate peritoneal lavage and dialysis. The aim of the present study was to describe a new modified percutaneous technique for the placement of peritoneal dialysis catheters and assess the effectiveness and safety of peritoneal lavage and dialysis used for treatment of necrotizing acute pancreatitis. We conducted a retrospective data review of 35 patients of necrotizing acute pancreatitis from January 2010 to December 2014 in Jilin City Central Hospital and The First Affiliated Hospital of ZheJiang University. In total, 18 patients underwent peritoneal lavage and dialysis after inserting catheters by our new technique (group A), whereas 17 patients underwent ultrasound-guided percutaneous catheter drainage (group B). By analyzing the patients' data, the drainage days and mean number of hours between the debut of the symptoms and the hospital admission were lower in group A (P < 0.05, P < 0.05, respectively). The complication rate of 5.6 and 17.6%, respectively (P = 0.261), and a mortality rate of 16.7 and 5.9% for each group, respectively (P = 0.316). Likewise, hospitalization time was similar for the group A: 31 ± 25.3 days compared with 42.8 ± 29.4 days in the group B (P = 0.211). Peritoneal lavage and dialysis can be used in necrotizing acute pancreatitis, and our new modified percutaneous technique offers the same complication and mortality rate as ultrasound-guided drainage but with a shorter drainage days.
