Outcomes in Pancreas Transplantation With Exocrine Drainage Through a Duodenoduodenostomy Versus Duodenojejunostomy.

Until recently, pancreas transplantation has mostly been performed with exocrine drainage via duodenojejunostomy (DJ). Since 2012, DJ was substituted with duodenoduodenostomy (DD) in our hospital, allowing endoscopic access for biopsies. This study assessed safety profiles with DD versus DJ procedures and clinical outcomes with the DD technique in pancreas transplantation. DD patients (n = 117; 62 simultaneous pancreas-kidney [SPKDD ] and 55 pancreas transplantation alone [PTADD ] with median follow-up 2.2 years) were compared with DJ patients (n = 179; 167 SPKDJ and 12 PTADJ ) transplanted in the period 1998-2012 (pre-DD era). Postoperative bleeding and pancreas graft vein thrombosis requiring relaparotomy occurred in 17% and 9% of DD patients versus 10% (p = 0.077) and 6% (p = 0.21) in DJ patients, respectively. Pancreas graft rejection rates were still higher in PTADD patients versus SPKDD patients (p = 0.003). Hazard ratio (HR) for graft loss was 2.25 (95% CI 1.00, 5.05; p = 0.049) in PTADD versus SPKDD recipients. In conclusion, compared with the DJ procedure, the DD procedure did not reduce postoperative surgical complications requiring relaparatomy or improve clinical outcomes after pancreas transplantation despite serial pancreatic biopsies for rejection surveillance. It remains to be seen whether better rejection monitoring in DD patients translates into improved long-term pancreas graft survival.

Does antecolic reconstruction for duodenojejunostomy improve delayed gastric emptying after pylorus-preserving pancreaticoduodenectomy? A systematic review and meta-analysis.

AIM: To evaluate whether antecolic reconstruction for duodenojejunostomy (DJ) can decrease delayed gastric emptying (DGE) rate after pylorus-preserving pancreaticoduodenectomy (PPPD) through literature review and meta-analysis. METHODS: Articles published between January 1991 and April 2012 comparing antecolic and retrocolic reconstruction for DJ after PPPD were retrieved from the databases of MEDLINE (PubMed), EMBASE, OVID and Cochrane Library Central. The primary outcome of interest was DGE. Either fixed effects model or random effects model was used to assess the pooled effect based on the heterogeneity. RESULTS: Five articles were identified for inclusion: two randomized controlled trials and three non-randomized controlled trials. The meta-analysis revealed that antecolic reconstruction for DJ after PPPD was associated with a statistically significant decrease in the incidence of DGE [odds ratio (OR), 0.06; 95% CI, 0.02-0.17; P < 0.00001] and intra-operative blood loss [mean difference (MD), -317.68; 95% CI, -416.67 to -218.70; P < 0.00 001]. There was no significant difference between the groups of antecolic and retrocolic reconstruction in operative time (MD, 25.23; 95% CI, -14.37 to 64.83; P = 0.21), postoperative mortality, overall morbidity (OR, 0.54; 95% CI, 0.20-1.46; P = 0.22) and length of postoperative hospital stay (MD, -9.08; 95% CI, -21.28 to 3.11; P = 0.14). CONCLUSION: Antecolic reconstruction for DJ can decrease the DGE rate after PPPD.

Duodenoduodenostomy in pancreas transplantation.

Enteric drainage (ED) using duodenojejunostomy (DJ) is an established technique in pancreatic transplantation. Duodenoduodenostomy (DD), an alternative ED technique, may provide unique advantages over DJ. We compared our experience with these two types of ED through a retrospective review of all pancreas transplants performed at our institution from November 2007 to November 2009. The allograft duodenum was anastomosed to the recipient jejunum or duodenum. Duodenal drainage was performed by a stapled or hand-sewn technique. Patient demographics, operative times, major post-operative complications, and graft survival data were analyzed. Of 57 pancreas transplants, DJ was performed in 36 patients, stapled DD in 14 patients, and hand-sewn DD in seven patients. Two DD grafts (9.5%) thrombosed compared with no DJ grafts (p = NS). Enteric leak and small-bowel obstruction occurred in 3 of 36 DJ patients and in two DD patients (p = NS). Gastrointestinal bleeding occurred more frequently in stapled DD compared with DJ (4 vs. 0, p < 0.015). In conclusion, DD is technically feasible with no increase in operative time or enteric complications. GI bleeding rates appear to be higher following DD (stapled) technique. Potential complications of DD should be balanced against the benefits conferred by this technique.

[Enteral zond feeding in patients with insolvensy of duodenum stump].

The most effective method of insolvency duodenum stump treatment is an active drenage of stump--zone within enteral zond feeding. Using of Y-shaped enterostomia with compressive intestine anastomosis avows to fulfill feeding during a long period of time. It is not followed with new complication even in peritonitis case. The method allows to lower the death level in two times.

A life-saving but inadequately discussed procedure: tube duodenostomy. Known and unknown aspects.

OBJECTIVE: The most successful method of managing the difficult duodenum, including the stump leakage, has been the tube duodenostomy technique, but it has not gained wide acceptance and is rarely used. The purpose of this study is to describe the details of the procedure for indication, technical approach, and postoperative care. METHODS: During the period from 1998 to 2006, a tube duodenostomy was performed in 31 patients for possible insecure duodenal stump closure during gastric resection, postoperative duodenal stump leakage, duodenal leak after primary closure of duodenum for perforation or injury, or anostomotic leak after choledochoduodenostomy. All of the tube duodenostomies were performed through the open end of the duodenum. We also inserted a T-tube into the common bile duct in 19 of 31 patients (61.2 %) with tube duodenostomy. RESULTS: A tube duodenostomy was performed in the primary operation in 15 of 31 patients. None of those 15 patients required a second operation, and there were no leaks and no deaths. Among the larger group (31 patients), there was one (3.2 %) duodenal stump leak after tube duodenostomy, and it ceased spontaneously; one patient had a subhepatic collection after removal of the duodenostomy tube, and three patients had associated incisional infections. Two patients died; one after a myocardial infarction and the other from irreversible sepsis. The mean length of hospital stay was 26.9 days. CONCLUSIONS: We conclude that tube duodenostomy is a simple, effective, and safe method to prevent rupture of an insecure duodenal stump or to treat the leakage from the duodenal stump or primary repair on the duodenum.

[14-year experience with surgical treatment of chronic pancreatitis]. / 14-letnie doswiadczenia w chirurgicznym leczeniu przewleklego zapalenia trzustki.

The authors discuss their own 14-year experience with surgical treatment of the chronic pancreatitis. They treated 64 patients of a mean age of 43 years. An abdominal pain, persisting in all patients, constituted the main indication to surgery. Forty patients underwent pancreatic enterostomy with Puestow technique, 19 patients resections of various extension, and 5 patients underwent pancreatic duodenostomy. Mortality rate in pancreatic enterostomy and pancreatic duodenostomy was 2.5% whereas mortality rate in resections was 5.3%. Complications were noted in 27.5% and 36.8% of patients, respectively. Pain was completely abolished or markedly reduced in 90% of patients. Forty eight (77.4%) out of 62 patients were identified and followed up. According to commonly used criteria, positive late results were achieved in 56.2% of patients, moderate in 29.2%, and poor result in 14.6% of the treated patients.

Pancreaticoduodenectomy (Whipple resection) in the treatment of chronic pancreatitis.

The armamentarium of the pancreatic surgeon must include multiple operative techniques, to be adapted to the clinical and anatomical findings in the patient with chronic pancreatitis. Pancreaticoduodenectomy is an essential component of this armamentarium. Its indications and limitations require continued refinement. Pancreaticoduodenectomy (Whipple operation) provides excellent results in the relief of the pain of chronic pancreatitis. The incidence of reoperation for control of pain after this procedure is less than after drainage procedures. The postoperative mortality rate in recent report is less than 2%. Whereas resection of pancreatic tissue diminishes pancreatic function, the metabolic deficits are partially compensated by the better nutritional status resulting from pain relief and discontinuation of narcotics. In experienced hands, pancreaticoduodenectomy would appear to be the procedure of choice in patients with small pancreatic ducts. In selected patients, it appears to be a good procedure and, possibly, the operation of choice when the disease is predominantly present in the head of the pancreas and/or the uncinate process, especially when strictures involve the common bile duct and duodenum. The authors prefer the procedure when a hard, chronically-inflamed mass is present in the head of the pancreas. In our experience, if the suspicion of malignancy of the head of the pancreas persists at operation, pancreaticoduodenectomy is the procedure of choice. Before undertaking resection, the individual surgeon must assess his/her own experience; a low risk is essential. The continuing alcoholic is not a candidate for pancreaticoduodenectomy. Those who will not stop drinking should seldom be accepted for resection. The same limitation exists for the narcotic addict, but few such patients are encountered today. In the authors' experience, the operation is excellent for the relief of pain. It is the lifestyle of the continuing alcoholic that poses the more significant problem.
