ABSTRACT

OBJECTIVE: To retrospectively analyze the wound issues for obese renal transplant patients, as well as post-transplant outcomes including graft and patient survival, hypothesizing improvement over the standard approach. As the obese population has expanded, minimally invasive renal transplant techniques have attempted to improve the issues of complications related to wounds and hernias. The anterior rectus sheath approach, which facilitates a minimal incision, has been adopted at our center for all renal transplants, including obese patients. METHODS: Between January 1, 2011 and December 31, 2014, 166 renal transplants were performed at the Charleston Area Medical Center with the new approach adopted in November 2012. Of the extraperitoneal transplants, 71 adult patients were classified as morbid/severe (≥35) or obese (30-34.9) by body mass index. Demographics, perioperative results, and outcomes were retrospectively collected for the conventional (CON) and anterior rectus sheath (ARS) approaches until August 21, 2015. RESULTS: The ARS and CON groups comprised 40 of 71 (56%) and 31 of 71 (44%) patients, respectively. The majority of demographics and perioperative data indicated no significant statistical differences between procedures (P < .05). Wound complications, incision length, operative time, and glomerular filtration rate at 6 and 12 months were significantly different. Multivariate calculations indicated procedure as the only variable expected to affect wound healing in obese patients. CONCLUSION: For obese patients, the ARS approach was shown to be an effective option that reduced wound complications and operative times. This easily adopted approach provides the obese and morbidly obese with comparable overall graft outcomes and significant improvement on wound complications.

ABSTRACT

BACKGROUND: Prevention of wound complications is an important goal in surgery, and reduction of modifiable risks factors are an important step towards protecting patients from further complications. Renal transplantation has sought to be more inclusive giving access to transplantation to complex patient populations, many of which have an increased risk of complications specifically obese recipients. Surgical techniques continue to advance and may contribute to reducing complications. We hypothesized that the Anterior Rectus Sheath (ARS) Approach would provide an open transplant with minimal damage and less wound complications, including fluid collections such as lymphoceles, when compared to the conventional technique (CON) with equivalent graft function and survival. MATERIALS AND METHODS: The ARS approach was adopted at our center in November of 2012. Medical records for 44 patients that underwent kidney transplantation at our Center between May 1, 2012 and March 31, 2013 were reviewed with data collected up to August 2015. Two were excluded (2 intraperitoneal transplants), leaving 22 in the ARS group and 20 in the CON group. RESULTS: Demographics, data, and perioperative factors were found to be similar, but operative and post-operative findings indicated significant differences between the groups. Significant reductions of wound complications, including fluid collections, were observed and operative time, incision length, and drain usage were improved with the ARS technique. Secondary outcome assessing overall patient outcomes showed no significant difference. CONCLUSION: This retrospective review case series quantified that this easily adopted modification of the conventional transplant technique is a safe, effective, and swift approach to renal transplantation with favorable graft results and improved surgical outcomes with less post-operative wound complications.

ABSTRACT

Benefits of pulsatile machine perfusion (pumping) of standard criteria donor (SCD) kidneys are unclear. Our center is located 4½ hours from our Organ Procurement Organization. We evaluated outcomes of pumping SCD kidneys under such circumstances by conducting a retrospective examination of all SCD kidneys transplanted between January 2007 and March 2012, comparing kidneys pumped (28 [group 1]) versus standard cold storage (77 [group 2]). Group 1 had fewer delayed graft function (DGF, 3.57% vs. 23.38%, p = 0.02) and slow graft function (SGF, 7.14% vs. 24.68%; p = 0.047) and faster serum creatinine recovery curve (p < 0.001) than group 2. Having a kidney pumped decreases the incidence (odds ratio [OR], 0.059) of DGF, SGF, or primary nonfunction. Group 1 were quicker to reach an estimated glomerular filtration rate (eGFR) >30 ml/min (OR, 4.186; confidence interval [CI], [2.448-7.157]) or an eGFR >60 ml/min (OR, 2.669; CI [1.255-5.679]). Pumping the SCD kidneys in a geographically remote transplant center tended to be better than those preserved in cold storage. However, except recovery curve of serum creatinine during the first postoperative month, other parameters failed to reach statistical significance in the post hoc examination of the contemporary groups. Prospective paired kidney study is required to scrutinize this finding.

ABSTRACT

OBJECTIVE: To describe keys to successful programmatic implementation of laparoendoscopic single-site (LESS)-living donor nephrectomy (LDN) in a small-volume center. Laparoscopic LDN has become the standard of care. Technically challenging LESS-LDN has been limited to high-volume centers. However, approximately half of all U.S. transplant centers perform ≤15 LDNs/year, including our center. METHODS: A hand-assisted laparoscopy (HAL) device was used as the LESS platform at a periumbilical midline incision. We used an adhesive drape to cover the platform to prevent gas leakage. A 30° telescope and 3-4 instruments were inserted through its gel-cap. After careful dissection, the kidney was bagged into a recovery device with an external handle before its vessels were ligated with staples and was then removed immediately through the LESS wound. RESULTS: LESS-LDN was successful in all of 10 living donors without any multisite laparoscopic or open conversion and without any instruments inserted through extra wounds. No patient had perioperative complications or received transfusions. Median operative time was 271 minutes with a warm ischemia time (WIT) of 3.5 minutes. Hospital stay averaged 2 days with visual analog pain score 4 of 10 at discharge and 2 of 10 at 2 weeks. All recipients recuperated well with immediate graft function. CONCLUSION: Our LESS-LDN technique offers improved cosmesis, favorable perioperative outcomes, and versatile options for conversion, if necessary, making it a viable approach for small-volume centers.
