RESUMEN
BACKGROUND: This dual-center, randomized controlled trial aimed to compare 2 types of intra-abdominal drains after pancreatic resection and their effect on the development of pancreatic fistulae and postoperative complications. METHODS: Patients undergoing pancreatic resection were randomized to receive either a closed-suction drain or a closed, passive gravity drain. The primary endpoint was the rate of postoperative pancreatic fistula. A secondary endpoint was postoperative morbidity during follow-up of 3 months. The planned sample size was 223 patients. RESULTS: A total of 294 patients were assessed for eligibility, 223 of whom were randomly allocated. One patient was lost during follow-up, and 111 patients in each group were analyzed. The rate of postoperative pancreatic fistula (closed-suction 43.2%, passive 36.9%, Pâ¯=â¯.47) and overall morbidity (closed-suction 51.4%, passive 40.5%, Pâ¯=â¯.43) were not different between the groups. We did not find any differences between the groups in reoperation rate (Pâ¯=â¯.45), readmission rate (Pâ¯=â¯.27), hospital stay (Pâ¯=â¯.68), or postoperative hemorrhage (Pâ¯=â¯.11). We found a significantly lesser amount of drain fluid in the passive gravity drains between the second and fifth postoperative days and also on the day of drain removal compared with closed-suction drains. CONCLUSION: The type of drain (passive versus closed suction) had no influence on the rate of postoperative pancreatic fistulae. The closed-suction drains did not increase the rate of postoperative complications. We found that the passive gravity drains are more at risk for obstruction, whereas the closed-suction drains kept their patency for greater duration.

PURPOSE: Patients who develop complications consume a disproportionately large share of available resources in surgery; therefore the attention of healthcare funders focuses on the economic impact of complications. The main objective of this work was to assess the clinical and economic impact of postoperative complications in pancreatic surgery, and furthermore to assess risk factors for increased costs. METHODS: In all, 161 consecutive patients underwent pancreatic resection. The costs of the treatment were determined and analyzed. RESULTS: The overall morbidity rate was 53.4%, and the in-hospital mortality rate was 3.7%. The median of costs for all patients without complication was 3,963 Euro, whereas the median of costs for patients with at least one complication was significantly increased at 10,670 Euro (P < 0.001). In multivariate analysis American Society of Anesthesiologists ≥ 3 (P = 0.006), multivisceral resection (P < 0.001) and any complication (P < 0.001) were independently associated with increased costs. CONCLUSION: Postoperative complications are associated with an increase in mortality, length of hospital stay, and hospital costs. The treatment costs increase with the severity of the postoperative complications. Those factors that are known to increase the treatment costs in pancreatic resection should be considered when planning patients for surgery.
RESUMEN
AIM: To study all the aspects of drain management in pancreatic surgery. METHODS: We conducted a systematic review according to the PRISMA guidelines. We searched the Cochrane Central Registry of Controlled Trials, EMBASE, Web of Science, and PubMed (MEDLINE) for relevant articles on drain management in pancreatic surgery. The reference lists of relevant studies were screened to retrieve any further studies. We included all articles that reported clinical studies on human subjects with elective pancreatic resection and that compared various strategies of intra-abdominal drain management, such as drain vs no drain, selective drain use, early vs late drain extraction, and the use of different types of drains. RESULTS: A total of 19 studies concerned with drain management in pancreatic surgery involving 4194 patients were selected for this systematic review. We included studies analyzing the outcomes of pancreatic resection with and without intra-abdominal drains, studies comparing early vs late drain removal and studies analyzing different types of drains. The majority of the studies reporting equal or superior results for pancreatic resection without drains were retrospective and observational with significant selection bias. One recent randomized trial reported higher postoperative morbidity and mortality with routine omission of intra-abdominal drains. With respect to the timing of drain removal, all of the included studies reported superior results with early drain removal. Regarding the various types of drains, there is insufficient evidence to determine which type of drain is more suitable following pancreatic resection. CONCLUSION: The prophylactic use of drains remains controversial. When drains are used, early removal is recommended. Further trials comparing types of drains are ongoing.

BACKGROUND: The morbidity of pancreatic resection remains high, with pancreatic fistula being the most common cause. The important question is whether any postoperative treatment adjustment may prevent the development of clinically significant postoperative pancreatic fistulae. Recent studies have shown that intraabdominal drains and manipulation using them are of great importance. Although authors of a few retrospective reports have described good results of pancreatic resection without the use of intraabdominal drains, a recent prospective randomized trial showed that routine elimination of drains in pancreaticoduodenectomy is associated with poor outcome. An important issue arises as to which type of drain is most suitable for pancreatic resection. Two types of surgical drains exist: open drains and closed drains. Open drains are considered obsolete nowadays because of frequent retrograde infection. Closed drains include two types: passive gravity drains and closed-suction drains. Closed-suction drains are more effective, as they remove fluid from the abdominal cavity under light pressure. However, some surgeons believe that closed-suction drains represent a potential hazard to patients and that negative pressure might increase the risk of pancreatic fistulae. Nobody has yet specifically dealt with the question of which kind of drainage is most appropriate in pancreatic surgery. METHODS/DESIGN: The aim of the DRAins in PAncreatic surgery (DRAPA) trial is to compare the closed-suction drain versus the closed passive gravity drain in pancreatic resection. DRAPA is a dual-centre, prospective, randomized controlled trial. The primary endpoint is the rate of postoperative pancreatic fistula; the secondary endpoint is postoperative morbidity with follow-up of 3 months. DISCUSSION: No study to date has compared different types of drains in pancreatic surgery. This study is designed to answer the question whether any particular type of drain might lower the rate of postoperative pancreatic fistula or other complications. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01988519. Registered 13 November 2013.

Despite recent improvements in surgical technique, the morbidity of distal pancreatectomy remains high, with pancreatic fistula being the most significant postoperative complication. A systematic review of randomized controlled trials (RCTs) dealing with surgical techniques in distal pancreatectomy was carried out to summarize up-to-date knowledge on this topic. The Cochrane Central Registry of Controlled Trials, Embase, Web of Science, and Pubmed were searched for relevant articles published from 1990 to December 2013. Ten RCTs were identified and included in the systematic review, with a total of 1286 patients being randomized (samples ranging from 41 to 450). The reviewers were in agreement for application of the eligibility criteria for study selection. It was not possible to carry out meta-analysis of these studies because of the heterogeneity of surgical techniques and approaches, such as varying methods of pancreas transection, reinforcement of the stump with seromuscular patch or pancreaticoenteric anastomosis, sealing with fibrin sealants and pancreatic stent placement. Management of the pancreatic remnant after distal pancreatectomy is still a matter of debate. The results of this systematic review are possibly biased by methodological problems in some of the included studies. New well designed and carefully conducted RCTs must be performed to establish the optimal strategy for pancreatic remnant management after distal pancreatectomy.

BACKGROUND: Postoperative pancreatic fistula is the main cause of morbidity after pancreatic resection. This study aimed to quantify the clinical and economic consequences of pancreatic fistula in a medium-volume pancreatic surgery center. METHODS: Hospital records from patients who had undergone elective pancreatic resection in our department were identified. Pancreatic fistula was defined according to the International Study Group on Pancreatic Fistula (ISGPF). The consequences of pancreatic fistula were determined by treatment cost, hospital stay, and out-patient follow-up until the pancreatic fistula was completely healed. All costs of the treatment are calculated in Euros. The cost increase index was calculated for pancreatic fistula of grades A, B, and C as multiples of the total cost for the no fistula group. RESULTS: In 54 months, 102 patients underwent elective pancreatic resections. Forty patients (39.2%) developed pancreatic fistula, and 54 patients (52.9%) had one or more complications. The median length of hospital stay for the no fistula, grades A, B, and C fistula groups was 12.5, 14, 20, and 59 days, respectively. The hospital stay of patients with fistula of grades B and C was significantly longer than that of patients with no fistula (P<0.001). The median total cost of the treatment was 4952, 4679, 8239, and 30 820 Euros in the no fistula, grades A, B, and C fistula groups, respectively. CONCLUSIONS: The grading recommended by the ISGPF is useful for comparing the clinical severity of fistula and for analyzing the clinical and economic consequences of pancreatic fistula. Pancreatic fistula prolongs the hospital stay and increases the cost of treatment in proportion to the severity of the fistula.

BACKGROUND: Castleman disease is an uncommon lymphoproliferative disorder most frequently occurring in the mediastinum. Abdominal forms are less frequent, with pancreatic localization of the disease in particular being extremely rare. Only seventeen cases have been described in the world literature. METHOD: This report describes an interesting and unusual case of pancreatic Castleman disease treated with laparoscopic resection. RESULTS: A 48-year-old woman presented with epigastric pain. CT scan showed a well-encapsulated mass on the ventral border of the pancreas. Endosonography with fine needle aspiration biopsy was performed. Biopsy showed lymphoid elements and structures of a normal lymph node. The patient was treated with laparoscopic distal pancreatectomy. The pancreas was transected with a Ligasure device and the pancreatic stump was secured with a manual suture. One year after surgery the patient was complaint-free and showed no signs of recurrence of the disease. CONCLUSIONS: Laparoscopic distal pancreatectomy is a feasible and safe method for the treatment of lesions in the body and tail of the pancreas. Transection of the pancreas with a Ligasure device offers the advantages of low bleeding and low risk of pancreatic fistula.

BACKGROUND: Gastrointestinal stromal tumors (GISTs) may arise in any part of the gastrointestinal tract; extra-gastrointestinal locations are extremely rare. Only a few cases of extragastrointestinal stromal tumor arising from the pancreas were reported. None of the reports described a long-term follow-up of the patients. METHOD: This report describes an interesting and unusual case of GIST arising from the pancreas. RESULTS: A 74-year-old female presented with a palpable abdominal mass. CT scan showed a large mass 11 x 8 x 4 cm originating from the tail of the pancreas. Percutaneous biopsy revealed a GIST predominantly with spindle cells, but some parts also contained epitheloid cells. The patient was treated by distal pancreatic resection with splenectomy. Immunohistochemistry of the tumor showed a staining pattern characteristic of GIST. The patient has achieved a long-term survival of five years and six months without any sign of recurrence of the disease. CONCLUSION: This is the first reported case of an extra-gastrointestinal stromal tumor arising from the pancreas treated surgically, with a long-term survival.

The major postoperative complication after open and laparoscopic distal pancreatectomy is pancreatic fistula. Different operative techniques have been tested to minimize this unpleasant complication. We evaluated a new technique for pancreatic stump reinforcement with synthetic glue after laparoscopic distal pancreatectomy. Ten female domestic pigs were divided into 2 groups; in group A (n=5), the pancreas was transected using an EndoGIA stapler, whereas in group B (n=5), the pancreas was transected using a Ligasure device and the pancreatic stump was reinforced with a hydrogel sealant. The clinical postoperative course was uneventful in all the cases. No differences were observed in pancreatic remnant healing between the groups, and only minor microscopic alterations of the healing process were found in the groups. The technique using Ligasure transection reinforced by the hydrogel sealant seems to be comparable with the standard transection technique using the stapler.

BACKGROUND/AIMS: Metastatic renal cell carcinoma (RCC) is a malignant tumor characterized by great variation in the clinical course and unusual sites of metastases. Metastases to the pancreas are, in general, rare. METHODOLOGY: A retrospective chart review of patients treated a single institution. RESULTS: Single center experience in 10 patients with this rare presentation of metastatic RCC is presented. In most cases, the course after diagnosis of RCC pancreas metastases was relatively favorable, specifically in patients treated with surgical removal of the metastases. The median survival from the diagnosis of RCC pancreas metastases was 56 months. CONCLUSIONS: The course of disease in patients with RCC pancreas metastases is often indolent. Long-term survival may be obtained after surgery even with suboptimal systemic therapy. An active therapeutic approach is warranted in these patients.

BACKGROUND/AIMS: The prognosis of biliary tract carcinomas is poor, and therapeutic efforts are limited mostly only to palliation. The aim of this study was to retrospectively evaluate the effectiveness and tolerability of intraluminal high dose rate brachytherapy in the treatment of bile duct and gallbladder carcinomas. METHODOLOGY: Thirteen patients with bile duct and gallbladder carcinomas were treated by brachytherapy administered through high dose rate remote afterloading system. Five patients after Roux-en-Y hepaticojejunoanastomosis were treated by intraluminal brachytherapy inserted via a diahepatal drain, and 8 inoperable patients were treated by intraluminal brachytherapy via a percutaneous biliary drain. RESULTS: After intraluminal brachytherapy, a control of icterus was observed in all patients. The treatment was well tolerated and mean survival was 275 days. CONCLUSIONS: The addition of intraluminal brachytherapy may be beneficial to patients with carcinomas causing biliary obstruction in whom bile drainage can be established.
