Pancreatoduodenectomy with subtotal stomach-preserving and uncut Roux reconstruction.

BACKGROUND/PURPOSE: Pylorus-preserving pancreatoduodenectomy (PD) has become the therapy of choice for resectable tumors located in the head of the pancreas and periampullary region. In addition, a distal gastrectomy may still be required for tumors located in the dorsal part of the pancreatic head or when there is evidence of proximal duodenal invasion. This may lead to postoperative complications, including gastric dumping, marginal ulceration, and bile reflux gastritis. This study reports on the postoperative course following subtotal stomach-preserving PD with the uncut Roux reconstruction diverting biliary and pancreatic secretions from the gastric remnant. METHODS: A technique combining subtotal stomach-preserving PD with the uncut Roux reconstruction was applied in 10 patients. The postoperative clinical follow-up data are reviewed, and clinical criteria of biliary gastric reflux and gastritis were evaluated. RESULTS: The postoperative course was uneventful in 4 patients and complicated in 6 patients. Delayed gastric emptying occurred in 3 patients. No deaths occurred in the postoperative period. One patient suffered from occasional nausea with abdominal discomfort for which endoscopy and cholescintigraphy were performed. Endoscopy confirmed complete occlusion of the afferent jejunal limb and showed marginal ulceration within the gastrojejunal anastomosis. Cholescintigraphy showed signs of enterogastric reflux. The check-up endoscopy following typical antisecretory therapy revealed complete ulcer healing. Four patients died of tumor recurrence 6, 7, 8, and 12 months following surgery. CONCLUSION: This pilot study suggests that the uncut Roux reconstruction may represent a good alternative to gastrointestinal reconstruction following PD. Further studies including the determination of intragastric bile acid concentration and radionuclide isotope scanning in a larger number of patients are warranted.

Reduction of biliary complication rate using continuous suture and no biliary drainage for duct-to-duct anastomosis in whole-organ liver transplantation.

Biliary complications (BC) following orthotopic liver transplantation (OLT) are related to various factors including surgical technique and use of biliary drains for a duct-to-duct (DD) anastomosis. Herein we have reported the influence of changes in surgical technique on BC following OLT in our center. From February 2002 to February 2007, we performed 101 whole-organ OLT with a DD anastomosis in 99 adults, of whom we analyzed 84 subjects. We excluded recipients who died within 30 days of OLT without any evidence of BC and 1 patient with a biliary stricture secondary to a hepatic artery thrombosis. Until late 2004, a DD anastomosis with interrupted sutures over an external biliary drain (DD/BD) was performed in 35 patients (Group I). Subsequently, no biliary drain was used for the DD anastomosis (DD/non-BD), using a continuous suture in 49 patients (Group II). The DD anastomosis with interrupted sutures over a biliary drain was associated with a higher incidence of both total (31% vs 8%; P = .008) and late BC (>30 days; 20% vs 2%; P = .008) with a trend toward more leaks (17% vs 4%; P = .06). All biliary leaks in patients with DD/BD reconstruction occurred at the exit site of the biliary drain following its removal. No significant differences were observed when we compared the incidence of biliary strictures and the necessity for surgical intervention. One patient died due to a BC. Our results indicated that a DD anastomosis performed with a continuous suture technique and no external biliary drainage reduced the incidence of BC after whole-organ OLT.

Factors determining the contamination of bone tissue procured from cadaveric and multiorgan donors.

There is an increasing demand for bone allografts that are widely used in orthopedic reconstructive procedures. The bone tissue may be harvested from two sources: cadavers and multiorgan donors. Providing safe and valuable bone allografts is of paramount importance. Contamination of allografts during bone retrieval seems to be one of the most important problems since pathogenic microorganisms might be responsible for postoperative infections and complications in the healing process. The purpose of our study was to identify all factors contributing to bacteriological contamination of harvested bones. Therefore, we have considered factors such as harvesting environment, explantation techniques, storage and preparation of allografts, number of preceding procurements from the same donor, procurement duration, and time interval between death and tissue procurement. The microbiological evaluation of allografts has been performed by taking cultures from all collected bones. Our study revealed significantly greater contamination rates of bone allografts harvested from morgue than from multiorgan donors. According to this observation, we suggest that orthopedic surgeons should pay particular attention to obtain more bones of the highest quality, personally participating in multiorgan procurements.
