Abstract
BACKGROUND The purpose of this study was to examine the natural history and growth rate of pancreatic serous cystadenomas (SCAs) to determine which factors lead to resection for these benign neoplasms. METHODS We reviewed retrospectively a prospectively maintained database, identifying patients diagnosed with SCAs of the pancreas. The diagnosis was made via a combination of classic imaging features with or without cyst aspiration results consistent with SCA. To determine growth rates, gamma regression models were used and the average was modeled using the log function. RESULTS A prospectively maintained database of 1,241 pancreatic cystic neoplasms was queried from 1998 to 2010. A total of 219 patients (18%) were diagnosed with SCA, 194 in the surveillance group and 25 in the resection group. Twenty patients underwent resection after initial imaging principally for presence of symptoms and indeterminate diagnosis, and 5 underwent resection after surveillance for development of symptoms and/or rapid rate of growth. Rate of growth increased at a steady state over time, with an estimated doubling time of 12 years (95% confidence interval, 7.8-21.5). CONCLUSION This study shows that growth patterns are similar for SCAs of the pancreas regardless of initial size. When doubling time is faster than 12 years, resection should be considered.

Abstract
OBJECTIVES Splenectomy is often performed during distal pancreatectomy for malignancy, yet little data exist demonstrating splenic involvement in distal pancreatic pathology. METHODS We retrospectively reviewed 81 distal pancreatectomies performed for suspected or known pancreatic malignancies from 6/1/05 to 7/6/11. Exclusion criteria included metastatic disease, previous splenic preserving distal pancreatectomy, or planned en-bloc resection, leaving 47 cases. Data collected included spleen, hilar lymph node, or splenic vessel involvement by malignancy as confirmed by final pathology report. This was correlated with preoperative computed tomography (CT). RESULTS Final pathology showed adenocarcinoma in 10 (21%) patients. Three patients with adenocarcinoma had invasion of the spleen, splenic vessels or nodes on pathology. The first involved the splenic flexure, necessitating en-bloc colon resection. The second had splenic artery involvement as identified by CT, but no malignancy within the spleen. The third had direct extension to one of 11 peri-splenic nodes with significant inflammatory reaction noted intraoperatively. CONCLUSIONS Splenectomy is not mandated for all distal pancreatic tumors, and the spleen can be preserved in an overwhelming majority of cases. Pre- and intraoperative factors can adequately identify the necessity of splenectomy, and the approach should be tailored to individual patients.

Abstract
Background In recent years, many advances in pancreatic surgery have been achieved. Nevertheless, the rate of pancreatic fistula following pancreatic tail resection does not differ between various techniques, still reaching up to 30% in prospective multicentric studies. Taking into account contradictory results concerning the usefulness of covering resection margins after distal pancreatectomy, we sought to perform a systematic, retrospective analysis of patients that underwent distal pancreatectomy at our center. Methods We retrospectively analysed the data of 74 patients that underwent distal pancreatectomy between 2001 and 2011 at the community hospital in Neuss. Demographic factors, indications, postoperative complications, surgical or interventional revisions, and length of hospital stay were registered to compare the outcome of patients undergoing distal pancreatectomy with coverage of the resection margins vs. patients undergoing distal pancreatectomy without coverage of the resection margins. Differences between groups were calculated using Fisher’s exact and Mann–Whitney U test. Results Main indications for pancreatic surgery were insulinoma (n=18, 24%), ductal adenocarcinoma (n=9, 12%), non-single-insulinoma-pancreatogenic-hypoglycemia-syndrome (NSIPHS) (n=8, 11%), and pancreatic cysts with pancreatitis (n=8, 11%). In 39 of 74 (53%) patients no postoperative complications were noted. In detail we found that 23/42 (55%) patients with coverage vs. 16/32 (50%) without coverage of the resection margins had no postoperative complications. The most common complications were pancreatic fistulas in eleven patients (15%), and postoperative bleeding in nine patients (12%). Pancreatic fistulas occurred in patients without coverage of the resection margins in 7/32 (22%) vs. 4/42 (1011%) with coverage are of the resection margins, yet without reaching statistical significance. Postoperative bleeding ensued with equal frequency in both groups (12% with coverage versus 13% without coverage of the resection margins). The reoperation rate was 8%. The hospital stay for patients without coverage was 13 days (5–60) vs. 17 days (8–60) for patients with coverage. Conclusions The results show no significant difference in the fistula rate after covering of the resection margin after distal pancreatectomy, which contributes to the picture of an unsolved problem.

Abstract
Minimally invasive surgical approaches for pancreatic resection have been established as feasible and safe. Whereas widespread application of laparoscopic distal pancreatectomy is in progress, the utilization of laparoscopic pancreaticoduodenectomy is still localized to a few centers because of the added complexity and advanced laparoscopic skills required. Comparative studies have demonstrated the typical advantages of minimally invasive approaches for pancreatic resection, namely, less blood loss and shorter hospital stay. Robotic assistance for laparoscopic approaches is gaining interest, but the true value added is still undefined. Significant discussion revolves around the appropriateness of minimally invasive approaches in pancreatic cancer. Although limited data and only short-term follow-up engender ongoing skepticism, the technical feasibility, existing reports in pancreatic cancer, and the lack of negative outcomes in other gastrointestinal cancers spark ongoing clinical evaluation. Minimally invasive surgical approaches have significant potential to improve the outcomes of pancreatic resection especially in pancreatic cancer patients in whom an optimal recovery is important for adjuvant treatment options. Larger experiences are forthcoming, and controlled trials are eagerly awaited; however, the feasibility of such is questionable because of the low incidence of resectable pancreatic cancer and the small number of centers performing minimally invasive pancreatectomy for malignancy.

Abstract
OBJECTIVE The aim of this systematic review is to determine the potential advantages of robotic distal pancreatectomy (RDP). STUDY SELECTION Both randomized and non-randomized studies. DATA EXTRACTION Two investigators independently selected studies for inclusion by article abstraction and full text reviewing. DATA SYNTHESIS Five non-RCTs were included in the review. The feasibility of RDP (95.4%) and spleen-preserving rate is between 50% and 100%. Mean OT varied between 298 min and 398 min with only completely robotic procedures, whereas mean OT was 293 in "laparoscopic/robotic" technique. Postoperative length of hospital stay ranged from 7 days to 13.7 days. The 30-day postoperative overall morbidity resulted between 0 and 18% of patients. CONCLUSIONS RDP is an emergent technology for which there are not yet sufficient data to draw definitive conclusions with respect to conventional or laparoscopic surgery. The mean duration of RDP is longer with Da Vinci robot, but hospital stay is shorter even if it is influenced by hospital protocols. We cannot make any conclusions comparing the outcomes to laparoscopic or open procedures here, since none of these studies are randomized, and we all know that most of these surgeons selected the easier cases for robotic procedures. For these reasons randomized controlled trials are recommended to better evaluate RDP cost-effectiveness.

Abstract
BACKGROUND Splenic preservation during a distal pancreatectomy (SPDP) may be performed with splenic vessel ligation, known as Warshaw's Technique (WT) or splenic vessel preservation (SVP). The consensus on which approach is best is divided. A systematic review of evidence in the literature was undertaken with the aim of analysing the merits and disadvantages of both WT and SVP. METHODS A systematic search of medical literature from 1985-2011 was undertaken to identify all comparative studies and case series on SPDP. Non-English papers, series with < 5 patients, technical reports and reviews were excluded. The remaining articles were reviewed considering the study design, surgical technique, outcomes and complications. RESULTS In 23 relevant studies, 356 patients underwent WT and 572 underwent SVP. In WT patients, the mean operating time (160 versus 215 min, P < 0.001), mean estimated blood loss (301 versus 390 ml, P < 0.001) and length of stay (8 versus 11 days, P < 0.001) was significantly less than the SVP patients, respectively. Considering complications, splenic infarction and splenectomy occurred more frequently in WT patients (P < 0.05). DISCUSSION WT is technically easier to perform than SVP but has a higher incidence of subsequent splenectomies. Surgeons should be able to perform both procedures and tailor the technique according to the patient.

Abstract
Pancreatic surgery is a complicated procedure leaving postoperative patients with an altered gastrointestinal (GI) anatomy and a potential for further surgical complications such as leaks and fistulas. Beyond surgical complications, these patients are prone to delayed gastric emptying, fat malabsorption, and hyperglycemia, with early satiety and poor appetite further compromising nutrition status. Many of these patients are malnourished prior to this major surgical procedure, and significant weight loss is common postoperatively. Does this affect their outcome? There seems to be a lack of consensus in this patient population regarding how to optimize nutrition and limit potential deleterious effects of this surgery. It is important to first understand the underlying disease condition and the effects to the gland, different forms of surgery with subsequent GI alterations, and common surgical and digestive complications. Once this is reviewed, existing nutrition support literature will be explored in attempts to determine the best nutrition management in this patient population.

Abstract
BACKGROUND Because of improvement in surgical technique and endocrine and exocrine insufficiency management, total pancreatectomy is being frequently performed, especially for benign or low-potential malignant diseases. The laparoscopic approach is rarely performed. SUBJECTS AND METHODS Our aim is to report two cases operated by the assisted laparoscopic approach and to describe a standardized surgical technique. RESULTS Two patients underwent laparoscopic total pancreatectomy with assisted minilaparotomy or the hand-assisted technique for degenerated intraductal papillary mucinous neoplasms (IPMNs) and neuroendocrine tumors with operative times of 270 and 360 minutes, estimated blood loss of 200 and 300 mL, and a hospital stay of 12 and 18 days, respectively. One patient was re-operated on postoperative Day 10 for bleeding from the hepaticojejunostomy probably related to an inadequate dose of antiproton inhibitors, necessitating refection of the anastomosis with an uneventful course. Pathological examination revealed degenerated IPMNs (T3N1R0) and well-differentiated neuroendocrine tumors (T2NOR0) with complete resection. After 6-10 months of follow-up, the diabetes is well controlled with insignificant episodes of hypoglycemia in 1 patient without any evidence of tumor relapse. CONCLUSIONS In selected patients laparoscopic total pancreatectomy appears safe and had many advantages over the open and other laparoscopic pancreatic resection approaches, including first laparoscopic abdominal exploration and no pancreatic anastomosis. Oncological rules can be respected, but further larger studies are needed before drawing conclusions.

Abstract
OBJECTIVE To evaluate the role of an absorbable fibrin sealant patch (TachoSil) in reducing postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP). BACKGROUND POPF remains the main complication after DP. METHODS This was a prospective, open, randomized, study in which patients undergoing elective DP were randomized to standard surgical suturing or stapling with or without TachoSil. The primary end point was the incidence of POPF according to International Study Group on Pancreatic Fistula criteria. Amylase level in drainage fluid, number of days until removal of drain, and duration of hospital stay were secondary end points. RESULTS A total of 275 patients were enrolled at 19 centers over a 2-year period (TachoSil, n = 145; standard, n = 130). Twenty percent of procedures were laparoscopic and 21% were spleen-preserving resections. The incidence of POPF was not significantly different between groups (TachoSil, 62%; standard 68%; P = 0.267). Grade A fistula rate was similar in both groups (TachoSil 54%; standard 55%), whereas the grade B + C fistula rate was 8% with TachoSil versus 14% without (P = 0.139). Amylase drainage level on postoperative day 1 was significantly reduced with TachoSil (P = 0.025). Median number of days until drainage removal and length of hospital stay were similar in both groups (7 and 10 days, respectively). CONCLUSIONS The POPF rate was higher than expected when International Study Group on Pancreatic Fistula criteria were strictly applied, although the majority were biochemical fistulas. TachoSil had no significant effect on the rate of POPF, although there was a significant reduction of amylase level in drainage fluid on postoperative day 1.

Abstract
INTRODUCTION Laparoscopic left-sided pancreatectomy (LLP) is an accepted technique for the treatment of benign and pre-malignant lesions of the left side of the pancreas, but there is still controversy on its use for malignant ones. OBJECTIVE To evaluate our results in LLP as a routine technique for primary lesions of the left pancreas. PATIENTS AND METHODS We performed LLP in 15 patients for primary lesions of the pancreas from November 2007 to November 2011. An intra-abdominal drainage was left in all cases, and the recommendations of the International Study Group for Pancreatic Fistula were followed. RESULTS The mean age of the patients was 64±13 years. Six radical spleno-pancreatectomies, 3 corporo-caudal with preservation of the spleen, and 6 pure distal (4 with preservation of the spleen). There was one conversion. The mean surgical time was 230±69 minutes. The mean post-operative stay was 8.1±7.6 days. At 90 days, complications were detected in 4 patients; 3 grade II and one grade V according to the modified classification of Clavien. There was one grade B pancreatic fistula. The diagnosis was a malignant neoplasm in 53% of cases. The number of resected lymph nodes in the cases where a radical resection was planned due to cancer was 21.7±11.5, there being negative margins in all cases. CONCLUSIONS LLP may be considered as a suitable technique for the treatment of primary pancreatic lesions, including malignant ones, provided that it is performed by groups with experience in pancreatic surgery and highly trained in laparoscopic surgery.

Abstract
Intraductal papillary mucinous neoplasm (IPMN) is a cystic tumor of the pancreas. The etiology is unknown, but increasing evidence suggests the involvement of several tumorigenesis pathways, including an association with hereditary syndromes. IPMN occurs more commonly in men, with the mean age at diagnosis between 64 and 67 years old. At the time of diagnosis, it may be benign, with or without dysplasia, or frankly malignant with an invasive carcinoma. Tumors arising from the main pancreatic duct are termed main-duct IPMNs, those involving the branch ducts, branch-duct IPMNs. In general, small branch-duct IPMNs are benign, particularly in asymptomatic patients, and can be safely followed. In contrast, main-duct tumors should be surgically resected and examined carefully for an invasive component. In the absence of invasion, patient's survival is excellent, from 94 to 100%. For patients with an IPMN-associated invasive carcinoma, the prognosis overall is better than those with a de novo pancreatic ductal adenocarcinoma, with a 5-year survival of 40% to 60% in some series. However, no survival advantage can be demonstrated if the invasive component in an IPMN patient is that of the conventional tubular type (versus mucinous carcinoma). Several histomorphologic variants are recognized, although the clinical significance of this "subtyping" is not well defined.

Abstract
OBJECTIVES Currently, laparoscopic distal pancreatectomy (LDP) is regarded as a safe and effective surgical approach for lesions in the body and tail of the pancreas. This review compares outcomes of the laparoscopic technique with those of open distal pancreatectomy (ODP) and assesses the efficacy, safety and feasibility of each type of procedure. METHODS Comparative studies published between January 1996 and April 2012 were included. Studies were selected based on specific inclusion and exclusion criteria. Evaluated endpoints were operative outcomes, postoperative recovery and postoperative complications. RESULTS Fifteen non-randomized comparative studies that recruited a total of 1456 patients were analysed. Rates of conversion from LDP to open surgery ranged from 0% to 30%. Patients undergoing LDP had less intraoperative blood loss [weighted mean difference (WMD) -263.36.59 ml, 95% confidence interval (CI) -330.48 to -196.23 ml], fewer blood transfusions [odds ratio (OR) 0.28, 95% CI 0.11-0.76], shorter hospital stay (WMD -4.98 days, 95% CI -7.04 to -2.92 days), a higher rate of splenic preservation (OR 2.98, 95% CI 2.18-3.91), earlier oral intake (WMD -2.63 days, 95% CI -4.23 to 1.03 days) and fewer surgical site infections (OR 0.37, 95% CI 0.18-0.75). However, there were no differences between the two approaches with regard to operation time, time to first flatus and the occurrence of pancreatic fistula and other postoperative complications. CONCLUSIONS Laparoscopic resection results in improved operative and postoperative outcomes compared with open surgery according to the results of the present meta-analyses. It may be a safe and feasible option for patients with lesions in the body and tail of the pancreas. However, randomized controlled trials should be undertaken to confirm the relevance of these early findings.

Abstract
The laparoscopic approach for benign and malignant lesions in the tail of the pancreas is becoming a more widely used approach. Multiple prospective studies have shown the feasibility and safety of laparoscopic distal pancreatectomy in single-center and multi-center settings. Laparoscopic distal pancreatectomy is a challenging procedure, because the pancreas is surrounded by critical structures and located in the retroperitoneum. Pancreatic fistula remains a common complication in the laparoscopic approach. Distal pancreatic aggressive tumors may not be appropriate for the laparoscopic approach due to the lack of oncologic safety studies.

Abstract
Pancreatic surgery represents one of the most challenging areas in digestive surgery. In recent years, an increasing number of laparoscopic pancreatic procedures have been performed and laparoscopic distal pancreatectomy (LDP) has gained world-wide acceptance because it does not require anastomosis or other reconstruction. To date, English literature reports more than 300 papers focusing on LDP, but only 6% included more than 30 patients. Literature review confirms that LDP is a feasible and safe procedure in patients with benign or low grade malignancies. Decreased blood loss and morbidity, early recovery and shorter hospital stay may be the main advantages. Several concerns still exist for laparoscopic pancreatic adenocarcinoma excision. The individual surgeon determines the technical conduction of LDP, with or without spleen preservation; currently robotic pancreatic surgery has gained diffusion. Additional researches are necessary to determine the best technique to improve the procedure results.

Abstract
BACKGROUND Advanced and delicate laparoscopic techniques are usually required for safe and successful laparoscopic spleen-preserving distal pancreatectomy. The unique characteristics of robotic surgical system are thought to be useful for this minimally invasive procedure. METHODS From September 2007 to May 2011, patients who underwent robot-assisted, spleen-preserving, distal pancreatectomy for benign and borderline malignant tumors of the pancreas were retrospectively reviewed. Perioperative clinicopathologic surgical outcomes were evaluated. RESULTS Twenty-two patients were attempted for robot-assisted, spleen-preserving, distal pancreatectomy, and in 21 patients (95.5 %), the spleen was saved either by splenic vessels conservation (SVC; n = 17, 81 %) or by splenic vessels sacrifice (SVS; n = 4, 19 %). Seven patients were male and 15 were female with a mean age of 43.2 ± 15.2 years. Pathologic diagnosis included MCT in five patients, SCT in five, SPT in four, IPMT in three, NET in three, and other benign conditions in two. The mean operation time was 398.9 ± 166.3 min, but it gradually decreased as experiences were accumulated (Rsq = 0.223, p = 0.023). Intraoperative blood loss was 361.3 ± 360.1 ml, and intraoperative transfusion was required in four patients (18.1 %). A soft diet was given for 1.2 ± 0.4 days, and the length of hospital stay was 7.0 ± 2.4 days postoperatively. Clinically relevant pancreatic fistula was noted in two patients (9.1 %) but was successfully managed conservatively. Most patients (87.5 %) showed patency in conserved both splenic vessels, and only two patients (12.5 %) had partially or completely obliterated in splenic veins in the SVC-SpDP group. Partially impaired splenic perfusion was observed in one patient in the SVS-SpDP group. The perfusion defect area decreased without any clinical symptom after 4 months. CONCLUSIONS The robotic surgical system is thought to be beneficial for improving the spleen-preservation rate in laparoscopic distal pancreatectomy. Robot-assisted approach can be chosen for patients who require spleen-preserving distal pancreatectomy.

Abstract
PURPOSE OF REVIEW Pancreatic resection remains among the most formidable and complex of abdominal surgical operations. Nonetheless, recent observations have continued to provide incremental improvement in both our evidence for treatment regimens and the technology, resulting in better outcomes. RECENT FINDINGS Neoadjuvant regimens appear to have promise, at least in local control and perhaps in long-term survival. More extensive operations focusing on perineural invasion along with minimally invasive laparoscopic and robotic techniques are attracting increasing attention. The effectiveness of major vascular resection remains controversial. Concentration of patients in centers of expertise has contributed to improved outcomes. SUMMARY Improved management of pancreatic resections for cancer with more extensive and less-invasive surgical techniques has increased the number of patients who are candidates for effective surgical treatment.

Revisiting vascular patency after spleen-preserving laparoscopic distal pancreatectomy with conservation of splenic vessels. Surg Endosc 2012; 26:1765-71. [PMID: 22223114 PMCID: PMC3351607 DOI: 10.1007/s00464-011-2108-0] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2011] [Accepted: 11/26/2011] [Indexed: 12/11/2022]
Abstract
Background We evaluated vascular patency and potential changes in preserved spleens after laparoscopic spleen-preserving distal pancreatectomy (SPDP) with conservation of both splenic vessels. Methods We retrospectively analyzed the patency of conserved splenic vessels in patients who underwent laparoscopic or robotic splenic vessel-conserving SPDP from January 2006 to August 2010. The patency of the conserved splenic vessels was evaluated by abdominal computed tomography and classified into three grades according to the degree of severity. Results Among 30 patients with splenic vessel-conserving laparoscopic SPDP, 29 patients with complete follow-up data were included in this study. During the follow-up period (median: 13.2 months), grades 1 and 2 splenic arterial obliteration were observed in one patient each. A total of five patients (17.2%) showed grade 1 or 2 obliteration in conserved splenic veins. Most patients (82.8%) had patent conserved splenic vein. Four patients (13.8%) eventually developed collateral venous vessels around gastric fundus and reserved spleen, but no spleen infarction was found, and none presented clinical relevant symptoms, such as variceal bleeding. There was no statistical difference in vascular patency between the laparoscopic and robotic groups (P > 0.05). Conclusions Most patients showed intact vascular patency in conserved splenic vessels and no secondary changes in the preserved spleen after laparoscopic splenic vessel-conserving SPDP.

Serous cyst adenoma of the pancreas: appraisal of active surgical strategy before it causes problems. Surg Endosc 2011; 26:1560-5. [PMID: 22179458 PMCID: PMC3351602 DOI: 10.1007/s00464-011-2070-x] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2011] [Accepted: 11/09/2011] [Indexed: 01/13/2023]
Abstract
Background Patients who are diagnosed with symptomatic or ambiguous serous cyst adenoma (SCA) need surgery. The purpose of this study is to suggest a potential management plan based on analysis of surgically treated SCAs. Methods Between August 1995 and December 2010, 38 patients with SCA were surgically treated. Data were analyzed retrospectively. Results Among 38 patients, 28 were female and ten were male. Mean age was 49.6 ± 14.1 years, and five patients (13.2%) were older than 65 years. Among the five patients, two were more than 70 years old. Seventeen patients (44.7%) were symptomatic, and the rest (21, 55.3%) were incidentally found to have SCA. Twenty-seven patients underwent open pancreatectomy, and 11 patients received laparoscopic distal pancreatectomy. Mean tumor size was 4.4 ± 2.8 cm. Most asymptomatic patients of SCA had a left-sided pancreatic tumor and distal pancreatectomy with or without splenectomy were frequently performed with short operative time and less blood transfusion (P < 0.05). Minimally invasive surgery was mostly applied to left-sided tumors less than 5 cm in size (11/19 vs. 0/6, P = 0.029). Combined resection of the right colon was performed in two patients (5.3%) due to severe adhesion associated with large tumors. Significant association was noted between age and tumor size in asymptomatic patients (correlation coefficient = 0.541, R2 = 0.293, P = 0.014). Postoperative pancreatic fistula was observed in five patients (13.2%, grade B) but could be managed conservatively. No mortality was found. Conclusion Before SCA causes symptoms or grows larger than 5 cm, an active surgical approach, such as minimally invasive surgery, needs to be considered.

Abstract
Remnant closure after distal pancreatectomy remains a surgical challenge and is still associated with a fistula rate of about 30%. Despite numerous technical modifications including the use of stapling devices, artificial patches and glue components, no important progress has been made concerning this topic within the last decade. Although tissue texture, co-morbidities and the type of resection may influence fistula rate, substantial improvement can probably be reached by further technical modifications. In addition to the avoidance of fistula development, the recognition and management of this complication is essential to achieve good postoperative outcome. The present review summarizes the currently available data on technical approaches, incidence and risk factors for failure of remnant closure, fistula-associated complications and management as well as the future perspectives in this field of surgery.
