Ferrer-Fàbrega J, Fernández-Cruz L. Exocrine drainage in pancreas transplantation: Complications and management. World J Transplant 2020; 10:392-403. [PMID: 33437672 PMCID: PMC7769732 DOI: 10.5500/wjt.v10.i12.392] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 11/23/2020] [Accepted: 12/08/2020] [Indexed: 02/06/2023] Open
Abstract
The aim of this minireview is to compare various pancreas transplantation exocrine drainage techniques i.e., bladder vs enteric. Both techniques have different difficulties and complications. Numerous comparisons have been made in the literature between exocrine drainage techniques throughout the history of pancreas transplantation, detailing complications and their impact on graft and patient survival. Specific emphasis has been made on the early postoperative management of these complications and the related surgical infections and their consequences. In light of the results, a number of bladder-drained pancreas grafts required conversion to enteric drainage. As a result of technical improvements, outcomes of the varied enteric exocrine drainage techniques (duodenojejunostomy, duodenoduodenostomy or gastric drainage) have also been discussed i.e., assessing specific risks vs benefits. Pancreatic exocrine secretions can be drained to the urinary or intestinal tracts. Until the late 1990s the bladder drainage technique was used in the majority of transplant centers due to ease of monitoring urine amylase and lipase levels for evaluation of possible rejection. Moreover, bladder drainage was associated at that time with fewer surgical complications, which in contrast to enteric drainage, could be managed with conservative therapies. Nowadays, the most commonly used technique for proper driving of exocrine pancreatic secretions is enteric drainage due to the high rate of urological and metabolic complications associated with bladder drainage. Of note, 10% to 40% of bladder-drained pancreata eventually required enteric conversion at no detriment to overall graft survival. Various surgical techniques were originally described using the small bowel for enteric anastomosis with Roux-en-Y loop or a direct side-to-side anastomosis. Despite the improvements in surgery, enteric drainage complication rates ranging from 2%-20% have been reported. Treatment depends on the presence of any associated complications and the condition of the patient. Intra-abdominal infection represents a potentially very serious problem. Up to 30% of deep wound infections are associated with an anastomotic leak. They can lead not only to high rates of graft loss, but also to substantial mortality. New modifications of established techniques are being developed, such as gastric or duodenal exocrine drainage. Duodenoduodenostomy is an interesting option, in which the pancreas is placed behind the right colon and is oriented cephalad. The main concern of this technique is the challenge of repairing the native duodenum when allograft pancreatectomy is necessary. Identification and prevention of technical failure remains the main objective for pancreas transplantation surgeons. In conclusion, despite numerous techniques to minimize exocrine pancreatic drainage complications e.g., leakage and infection, no universal technique has been standardized. A prospective study/registry analysis may resolve this.

Adler JT, Zaborek N, Redfield RR, Kaufman DB, Odorico JS, Sollinger HW. Enteric conversion after bladder-drained pancreas transplantation is not associated with worse allograft survival. Am J Transplant 2019; 19:2543-2549. [PMID: 30838785 DOI: 10.1111/ajt.15341] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Revised: 02/24/2019] [Accepted: 02/26/2019] [Indexed: 01/25/2023]
Abstract
In the early experience of pancreas transplantation, bladder drainage was favored, but it often caused urologic, metabolic, and infectious complications that necessitated conversion to enteric drainage. Long-term graft survival after enteric conversion and the impact of time interval from transplantation to enteric conversion on graft survival is poorly understood. We studied all bladder-drained first-time pancreas transplantations performed at the University of Wisconsin from 1985 to 2000. Time to conversion was estimated with the Kaplan-Meier technique, whereas risk factors associated with conversion were estimated via a time-varying Cox proportional hazards model. Of 386 bladder-drained pancreata, 162 (41.9%) eventually required enteric conversion, 29 (17.9%) within the first year. Median time to conversion varied by indication: 0.68 years for surgical, 3.1 years for urologic, and 2.7 years for metabolic disorders. In a time-varying Cox model adjusting for donor and recipient factors, enteric conversion did not affect the risk of pancreas graft loss (hazard ratio [HR] 0.86, P = .26). Kidney survival was not associated with enteric conversion. When necessary due to symptoms or complications, enteric conversion of bladder-drained pancreata is safe and does not affect overall graft survival. This relationship appears to be true no matter when the conversion is performed.

Abstract
Since the inception of pancreas transplant as a treatment for type 1 diabetes mellitus, there has been considerable debate about the best way to manage exocrine secretions and monitor patients for graft rejection. For patients who undergo bladder exocrine drainage of a pancreatic allograft, a bladder-to-enteric drainage conversion can serve as a rescue procedure in case of anastomotic leaks or other complications. However, this procedure is associated with its own complications, including a rarely described enterovesical fistula. Here we report on a 45-year-old man who underwent a simultaneous kidney and pancreas transplant with bladder drainage to the latter. He developed a pancreatic allograft duodenal leak (duodenal-vesical anastomosis) requiring a bladder-to-enteric drainage conversion. The patient returned 2 weeks after discharge with an enterovesical fistula. He was treated nonsurgically with intravenous antibiotics, bowel rest, and parenteral nutrition, and the fistula successfully closed in approximately 2 weeks. Overall, enterovesical fistula formation is a rare but treatable complication that can occur after a bladder-to-enteric drainage conversion of a pancreatic transplant allograft. It can be managed nonsurgically, which is preferable in these immunocompromised patients.

Abstract
Since the first pancreas transplants in the early 1960s, whole-organ pancreas transplantation, either alone or combined with kidney transplantation, has become commonplace in many countries around the world. Whole-organ pancreas transplantation is available in the UK, with ~200 transplants currently carried out per year. Patient survival and pancreas graft outcome rates are now similar to other solid organ transplant programmes, with high rates of long-term insulin independence. In the present review, we will discuss whole-pancreas transplantation as a treatment for diabetes, focusing on indications for transplantation, the nature of the procedure performed, graft survival rates and the consequences of pancreas transplantation on metabolic variables and the progression of diabetes-related complications.

Abstract
BACKGROUND Pancreas transplant (PT) is an established treatment for patients with diabetes mellitus. Diagnosis of rejection has continued to be problematic. In 2007, a new technique of PT with gastric exocrine (P-G) drainage was first performed at our institution. This technique facilitates access to pancreas allograft. The purpose of this study was to compare our experience with PT using P-G technique and the technique of portal enteric (P-E) with venting jejunostomy. STUDY DESIGN Thirty patients who underwent PT between 2007 and 2009 (G-I) and 30 consecutive patients before this time (G-II) were studied. In both groups arterial and venous anastomosis was similar to standard P-E technique. In G-I, the end of allograft jejunum was anastomosed to the anterior aspect of the stomach. In the G-II, allograft duodenum was anastomosed to the Roux-en-Y and end of Roux-en-Y was brought out as venting jejunostomy. RESULTS Donor and recipient demographic data, number of antigen matches, and immunosuppressant were similar in both groups. All patients achieved euglycemia. In G-I, 3 patients underwent pancreatectomy, 2 owing to vessel thrombosis and 1 owing to chronic rejection. Two patients died with functioning pancreatic allografts. In G-II, 1 pancreas was removed owing to vessel thrombosis. Seven patients with cytomegalovirus and 4 patients with rejection in G-I were diagnosed with endoscopy of allograft duodenum. One-year patient and graft survivals were similar. CONCLUSIONS This technique has proven to be safe with good patient and allograft survival. Access to donor duodenum and pancreas allograft via endoscopy is unique to this technique and provides the added advantage of life-long easy access to allograft.

Abstract
PURPOSE Bladder drainage (BD) of pancreatic transplants is associated with a unique set of complications. We intended to analyze the incidence, indications, complications and long-term results of enteric conversion procedures (EC). METHODS Using a prospective database, 32 EC patients out of 433 simultaneous pancreas-kidney-transplant (SPK) recipients were identified. Graft and patient survival rates were compared with those after primary enteric drainage (ED). RESULTS The mean SPK-EC interval was 5.0 yr, and the mean patient follow-up was 13.8 yr. Indications for EC were genitourinary symptoms (62.5%), duodenal complications (15.6%), graft pancreatitis (12.5%), pyelonephritis (6.3%), and metabolic acidosis (3.1%). All patients reported significant long-term resolution of symptoms. Surgical complications, reoperations, early graft loss, and 30-d mortality occurred in 31.3%, 25.0%, 6.3%, and 3.1% of cases, respectively. Pancreatic graft and patient survival rates at 1, 5, and 10 yr after SPK were comparable between EC patients and ED patients at the same institution. CONCLUSION For the treatment of symptoms associated with BD, EC results in excellent long-term graft function and significant resolution of symptoms even years after SPK. Postoperative morbidity after EC including early reoperation and graft loss, however, has to be considered.

Abstract
BACKGROUND Although there is a tendency to perform enteric drainage of pancreas transplants in simultaneous pancreas-kidney (SPK) transplantation, bladder drainage is still preferable in pancreas transplantation alone (PTA) or after a previous kidney transplantation (PAK). Our hypothesis was that enteric conversion of a bladder drained pancreas is an effective and safe procedure. We studied the complication rate and physiological effects of enteric conversion in patients with primary bladder-drained SPK transplantation. PATIENTS We performed 51 enteric conversions in bladder-drained SPK transplant recipients. As we observed a low complication rate, with time enteric conversions were also performed for less strict and severe indications. RESULTS The main indications for conversion were urological problems, metabolic complications and reflux-pancreatitis. The median transplantation-conversion interval was 12 months (range 2-40 months). Post-operative complications consisted of seven urinary tract infections, two low-grade superficial wound infections, one minor bleeding, one phlebitis and one paralytic ileus. In two patients, a relaparotomy was necessary. No graft rejection following enteric conversion was found. Long-term renal and pancreatic function were not affected by the enteric conversion. Three-year patient, kidney and pancreas survival rates after enteric conversion were 93, 97 and 93%, respectively (censored data). CONCLUSION Enteric conversion after pancreas transplantation is an effective and safe procedure. Therefore, we suggest a policy of a two-step approach of primary bladder drainage followed by an enteric conversion of the pancreas in a selected group of SPK patients.

Abstract
The method of exocrine diversion in pancreas allograft continues to be controversial due to the advantages versus disadvantages of bladder versus enteric techniques. Bladder drainage (BD) exposes the patient to urological and metabolic problems that may require conversion to enteric drainage (ED). The purpose of this study was to review our initial experience of conversion from BD to ED for patients who underwent pancreas transplantation originally with bladder diversion. Among 114 pancreas transplantation performed with BD, from January 1996 to April 2003, 60 were simultaneous pancreas-kidney transplantation (SPKT), 35 were pancreas transplantation alone (PA), and 19 were pancreas after kidney transplantations (PAK). Twenty-three (20.2%) cases were excluded due to early death of the patient or the graft, yielding an analyses of 91 patients. Enteric conversion (EC) was performed in 14 (15.4%) patients with a mean follow-up of 15.7 months (range, 3-51 months) after transplantation including 8 (8.8%) SPKT, 4 (4.4%) PAK, and 2 (2.2%) PA. No surgical morbidity or mortality was observed related to EC. All patients had complete resolution of the initial problem with preservation of pancreatic function. EC represents an easy, safe procedure with low morbidity and mortality rates, representing the option of choice for patients with persistent urological or metabolic disturbances.

Abstract
We review our experience with enteric conversion of previously bladder-drained pancreas transplants (PTx) using a short perioperative course of octreotide (OCT). Between July 1994 and December 2001, 45 consecutive primary bladder-drained PTx were performed. Immunosuppression consisted of a combination of tacrolimus, mycophenolate mofetil and steroids after induction with monoclonal or polyclonal antibodies. A total of 16 patients underwent enteric conversion at an average of 3 months after the initial transplant. Each patient received OCT perioperatively. We report no technical complications with the exception of one superficial wound infection and good early and late PTx survival rates. Perioperative treatment with octreotide is well tolerated and may reduce technical complications while performing enteric conversion of previously bladder-drained PTx.

Abstract
UNLABELLED The majority of simultaneous kidney-pancreas (SPK) transplants are being performed with portal-enteric drainage, which does not allow easy access to the donor pancreas. By adding a temporary venting jejunostomy (TVJ) we have been able to closely monitor patients for bleeding, anastomotic leak and rejection. METHODS Retrospective chart review of 29 patients undergoing SPK with PE drainage from December 1996 to December 2001. RESULTS Median follow-up was 32 months. Patient, kidney and pancreas graft survival were 93%, 90% and 93%, respectively. The most common early complications were wound infections and bleeding. No patient suffered vessel thrombosis. The most common late (greater than 3 months post-transplant) complication was gastro-intestinal bleeding. Adequate tissue was obtained for biopsy in 100% of patients with suspected pancreatic rejection. The TVJ allowed one patient to undergo donor pancreas ERCP that demonstrated the site of a pancreatic duct leak. Duodenal stump leak and anastomotic bleeding were diagnosed in one patient each via the TVJ. The median time to takedown of the TVJ was 14 months. CONCLUSION TVJ allows patients an easy method of graft surveillance, is well tolerated, and has an acceptable complication rate. The TVJ allows access to diagnose anastomotic leak, cauterize bleeding mucosa, perform ERCP and biopsy the pancreas allograft.

Abstract
PURPOSE Bladder drainage of pancreatic exocrine secretions during pancreas transplantation can lead to significant urological complications. Our experience with cystoenteric conversion (CEC) is reviewed with respect to safety and efficacy. Select patients underwent concurrent reduction cystoplasty. MATERIALS AND METHODS A total of 255 pancreas transplantations were performed at the University of Washington between 1990 and 2001, of which 236 were bladder drained and 33 required enteric conversion of bladder drainage. An additional patient from an outside institution required conversion. These cases were reviewed retrospectively. Of the patients 21 with large capacity (greater than 500 ml) bladders underwent concurrent reduction cystoplasty. RESULTS Mean age of the 20 male and 14 female patients was 44 years (range 33 to 60) and mean interval between transplantation and CEC was 4.3 years (0.6 to 9). The most frequent indication for CEC was recurrent urinary tract infections (15 of 34 cases, 44%). Mean followup after CEC was 2.5 years (range 0.3 to 6.5). Six complications requiring reoperation were seen in 5 of the 34 patients (15%), one of which led to death (3%). Normal pancreatic graft function persisted in 30 of the 34 cases (88%). After reduction cystoplasty mean bladder capacity in all 34 cases decreased from 900 to 465 ml intraoperatively (p <0.0001) and from 650 to 362 ml in 9 according to urodynamics (p <0.015). Of the patients 30 (88%) experienced resolution of symptoms, while 3 (9%) experienced improvement and 1 (3%) continued to have recurrent infections. CONCLUSIONS Although we advocate maximal conservative treatment of the urological complications of pancreas transplantation, CEC offers safe and effective management of these complications, and can easily be combined with reduction cystoplasty in select cases to optimize postoperative voiding function.

Abstract
OBJECTIVE To evaluate portal-enteric (PE) pancreas and kidney transplantation with venting jejunostomy (VJ) for its efficacy, safety, and reproducibility. SUMMARY BACKGROUND DATA Simultaneous pancreas and kidney transplantation for patients with long-standing insulin-dependent diabetes mellitus that progresses to renal failure has revolutionized their treatment and quality of life. A current clinical focus is to refine the technical aspects of this procedure. Simultaneous pancreas and kidney transplantation with PE anastomosis with VJ appears to offer several advantages over bladder drainage. VJ allows initial decompression of the enteric anastomosis, monitoring of pancreatic function by ostomy amylase, and simple access for endoscopic evaluation and biopsy of the allograft. METHODS Simultaneous pancreas and kidney transplantation with VJ was performed in 21 patients from December 1996 to October 2000 at Willis Knighton/LSU Regional Transplant Center. All patients had long-standing insulin-dependent diabetes mellitus and subsequent renal failure. They were evaluated at the time of surgery by a multidisciplinary transplant team and monitored for numerous factors, including length of hospital stay, immunosuppressive regimen, and ischemia times. All patients had intermittent visual and biochemical evaluation of pancreatic secretions monitored by means of the VJ. RESULTS Of the 21 patients, 10 were women and 11 were men. Four patients were black and 17 were white. The mean age at transplantation was 38 years; average human leukocyte antigen (HLA) match was one; and average cold ischemia time was 12 hours. The median hospital stay was 16 days. Four episodes of postoperative bleeding requiring exploration occurred in four patients. Postoperative wound infections developed in four patients. There were 12 episodes of rejection in nine patients. All patients with suspected acute pancreatic rejection underwent endoscopy by means of the VJ and duodenal biopsy for evaluation. Two patients lost pancreatic function subsequent to kidney failure, one secondary to noncompliance and the other as a result of hemolytic-uremic syndrome. Patient, kidney, and pancreatic survival rates were 100%, 90%, and 90%, respectively. The mean follow-up period was 25 (range 2-48) months. CONCLUSION The authors believe that PE pancreatic drainage with VJ is a more physiologic method to perform pancreatic transplantation than bladder drainage. PE drainage allows rapid diagnosis of acute rejection and anastomotic leak and provides a simple way to monitor ostomy amylase and transplant duodenal bleeding. This technique is safe and has minimal associated complications.

Abstract
AIMS This review examines the status of vascularized pancreas transplantation as a treatment for Type 1 diabetes mellitus (DM). METHODS The world literature, with a particular emphasis on data from the International Pancreas Transplant Registry (IPTR), is reviewed and interpreted particularly for clinical indications and outcome. RESULTS Over 9000 cases of vascularized pancreas transplant (VPT) have been registered, with insulin dependence approaching 82% at 1 year with 94% patient survival. The majority of transplants are simultaneous pancreas and kidney (SPK) transplants, with far fewer pancreas after kidney (PAK) or pancreas transplants alone (PTA). The success rates differ between the procedures but are generally improving as technical advances, improvements in immunosupression and greater experience are gained. The most obvious advantage is an improved quality of life (QoL) but there are risks associated with the procedure and with the immunosuppression. There is some evidence coming to light of a very slow beneficial effect on microvascular complications. CONCLUSIONS VPT is an attractive option to offer Type 1 DM patients who need or already have a renal allograft. Patients have to decide between the increased surgical risk and the risks of long-term immunosuppression and the benefits of improved QoL. In the absense of end-stage renal failure (ESRF) there is no justification for PTA, except where the diabetes itself poses a greater risk to life than the transplantation procedure.

Abstract
BACKGROUND Although bladder drainage of the pancreas remains the most common site for drainage of exocrine secretions, enteric drainage is becoming more common in the United States. The most common cause of morbidity after pancreas transplantation is infection, particularly recurrent urinary tract infection. METHODS We examined the incidence of infectious complications for enteric-drained (ED) versus bladder-drained (BD) simultaneous pancreas-kidney transplants (PTx) to determine the incidence of post-transplant infection. The patient cohort included simultaneous pancreas-kidney PTx recipients from June 1995 through August 1997 using a similar induction protocol with antithymocyte globulin, mycophenolate mofetil, prednisone, and Neoral. During this time period, 48 BD PTx and 78 ED PTx were performed. Demographic data including age of transplant, gender, race, and duration of initial hospital stay were similar. However, mean follow-up for the BD PTx was 1.9 years vs. 0.9 years for ED PTx. Rejection, infection, and graft and patient survival rates were estimated by the method of Kaplan and Meier. RESULTS For the entire cohort, 1-year patient survival was 98%, kidney survival 94%, and pancreas survival 93%. There was no difference in survival between ED or BD PTx. At 6 months, kidney transplant rejection had occurred in 38% of BD PTx vs. 30% of ED PTx. Steroid resistant rejection was similar (BD 19%, ED 17%). Postoperative pancreatic leak occurred in 12% BD PTx and 5% ED PTx (P=0.06). There was no significant difference in time to first infection or first abdominal infection between groups. Opportunistic infections were much less likely to occur in ED recipients by 1 year (12% vs. 31%, P=0.002). Both cytomegalovirus infection rates (BD 21% vs. ED 8%, P=0.04) and fungal infection rates (BD 17% vs. ED 4%, P=0.04) were lower in ED PTx. The rate of first urinary tract infection was dramatically decreased with ED. At 1 year, only 20% of ED PTx developed a urinary tract infection vs. 63% of BD PTx (P=0.0001). CONCLUSION Enteric drainage of the pancreas is more physiologic, has similar results to bladder drainage, but has less infectious complications, particularly urinary tract infections.
