Abstract
Background Perforated marginal ulcers (PMUs) are a feared long-term complication following pancreaticoduodenectomy (PD), which always require relaparotomy compared to marginal ulcers. Methods First, we performed a retrospective chart review for all patients who underwent PD from 2007-2016 to identify incidence and risk factors associated with PMUs. Second, we analyzed follow up gastroscopies in all patients undergoing PD from 2007-2011 to identify the overall incidence of marginal ulcers. Results A total of 725 patients underwent PD in the retrospective study period. 17 patients (2.3%) suffered from PMU at a median postoperative time of 13 months. These patients were significantly younger (median age: 49 vs. 62 years; P=0.02) and suffered most often from chronic pancreatitis (P<0.001). Smoking and alcohol consumption were significantly more common (P=0.01 and P=0.023). An elevated level of carcinoembryonic antigen and chronic pancreatitis were identified as independent risk factors. Overall, 373 patients were enrolled for prospective analysis. Marginal ulcers occurred in 5-5.9% over a postoperative period of 5 years. Conclusions Continuous treatment with proton-pump inhibitors for at least 5 years, immediate smoking cessation and follow-up gastroscopies are obligate for patients undergoing PD to avoid marginal ulcers and PMUs.

Abstract
Solid pseudopapillary neoplasm (SPN) is a rare tumor with malignant potential which is generally located in the tail of pancreas. The prevalence of SPN has increased with widespread use of cross sectional imaging. SPN is often misdiagnosed due to nonspecific clinical presentation and accurate diagnosis is essential for optimal management. Endoscopic ultrasound-FNA with immunohistochemistry can help in preoperative diagnosis. Surgery is the treatment of choice and a successful R0 resection is curative. Overall, SPN has a good prognosis. This review article focuses on pathogenesis, diagnosis and management of SPN.

Abstract
The aim of this article was to investigate and emphasize the clinical benefits of organ-preserving surgeries by comparing the pancreatic head resection with segmental duodenectomy (PHRSD), pylorus-preserving pancreatoduodenectomy (PPPD), and classic pancreatoduodenectomy (PD).A retrospective analysis of PHRSD (20 patients), PPPD (42 patients), and PD (92 patients) with benign lesions, low-grade malignancies, or early-stage carcinomas at the pancreatic head was performed since 2008. The intraoperative and postoperative courses and a long-term statuses were compared.The overall average age of the patients in 3 groups was 48.82 years old (range 12-76). The mean operative time and the blood loss were significantly less in the PHRSD and PPPD groups than that in the PD group (P < .05), but there were no differences between the PHRSD and PPPD groups. The possibilities of postoperative complications were equivalent in all 3 groups. During an average follow-up time of 61.1 months, there were no recurrence or distant metastasis happened. Patients in the PHRSD and PPPD groups had a better long-term nutritional status because they had less body weight loss (P < .01), and suffered less from long-term diarrhea (P < .001) than that in the PD group. However, the results in the PPPD group seemed to be better than that in the PHRSD group.PHRSD and PPPD are ideal procedures of organ-preserving pancreatectomy to fulfill the curative goals of benign lesions, low-grade malignancies, or early-stage carcinomas at the pancreatic head. It was proved to be operative safe and could bring patients with a better nutritional status and quality of life after surgery. However, PHRSD was more difficult with no better long-term benefits than PPPD, which asked a comprehensive consideration when made the surgical choice.

Abstract
BACKGROUND Pancreatic enzyme replacement therapy (PERT) is widely applied to patients with exocrine pancreatic insufficiency (EPI), but its effect and safety has not been quantified. Therefore we performed a meta-analysis to determine the efficacy and tolerance of PERT on patients with EPI. MATERIALS AND METHODS PubMed, Medline, Cochrane library database, Evidence-based medicine/clinical trials published before December 2016 were searched by two independent reviewers to identify prospective randomized controlled trials (RCTs). RESULTS Seven RCTs, randomizing a total of 282 patients, were filtrated and assessed qualitatively (Jadad score). PERT increased CFA (WMD: 26.56, 20.35 to 32.76, I2= 79.6%, P < 0.001) compared with baseline, and CFA (WMD: 17.97, 12.61 to 23.34, I2 = 76.7%, P < 0.001) vs. placebo. Meanwhile, CNA, SFE, SNE and SW were significantly improved in PERT compared with baseline and placebo, with no statistical differences in adverse events. Subgroup analysis indicated that standard forms of PERT displayed more effectiveness with significantly decreased heterogeneity, and large sample size also reduced the heterogeneity to some degree. CONCLUSIONS PERT is demonstrated to be effective and tolerable in patients with EPI, especially using standard administration of PERT. Larger and higher quality studies on EPI are demanded to long-term effect of standard PERT treatment.

Abstract
Surgical resection remains the only potentially curative therapy for pancreatic cancer, despite a high rate of systemic recurrence. Because of local invasion or distant spread, a minority of patients presenting with pancreatic cancer are candidates for surgery. Although perioperative mortality is low in high-volume settings, pancreatic surgery remains associated with considerable morbidity. Minimally invasive and robotic surgical techniques are increasingly used for pancreatic resection, although not always applicable to all patients. Strategies to extend the benefits of margin-negative surgical resection to more patients include surgery with vascular resection and reconstruction for locally invasive tumors, and resection after neoadjuvant therapy.

Abstract
BACKGROUND Pancreatic fistula (PF) remains the most serious complication after digestive surgery. It is difficult to prevent because of the inability to visualize the leakage of pancreatic juice during surgery or to evaluate the protease activity of leaked fluid, which is responsible for PF formation. METHODS The fluorescence intensities of a chymotrypsin probe (glutaryl-phenylalanine [corrected] hydroxymethyl rhodamine green with added trypsin) in pancreatic juice and in intestinal or abdominal fluids drained after pancreatic resection were evaluated. The chymotrypsin probe was sprayed on to filter papers that had been placed on the resected pancreatic stump in patients undergoing pancreaticoduodenectomy or central pancreatectomy. The ability of this technique to visualize the leakage of pancreatic juice and predict postoperative PF formation was assessed. RESULTS The fluorescence intensity of the chymotrypsin probe in 76 fluid samples correlated positively with amylase levels (r(s) = 0.678, P < 0.001). The fluorescence patterns of the pancreatic stump were classified grossly into the three types: duct (fluorescence signal visualized only on the stump of the main pancreatic duct, 16 patients), diffuse (ductal stump and surrounding pancreatic parenchyma, 7) and negative (no fluorescence signal, 7). Symptomatic PFs developed in 13 of 23 patients with duct- or diffuse-type fluorescence, but in none of the seven patients with negative-type fluorescence (P = 0.008). CONCLUSION The chymotrypsin probe enabled determination of the protease activity in drained pancreatic fluid samples and allowed real-time visualization of pancreatic juice leakage during surgery.

Abstract
Glucose homeostasis is significantly altered immediately after partial pancreatectomy. The present study examined the long-term consequences of a hemipancreatectomy in 10 patients with chronic pancreatitis and 10 patients with benign pancreatic and extrapancreatic tumors. A 240-minute oral glucose challenge was performed before and shortly after pancreatic surgery, as well as after a follow-up of 3.1 ± 0.5 years. Plasma concentrations of glucose, insulin, and C-peptide were determined; and indices of insulin sensitivity and insulin secretion were calculated. In both groups of patients, fasting and postchallenge glucose concentrations were significantly altered immediately after surgery, but returned to preoperative levels at the time of follow-up (P < .0001). Postchallenge insulin and C-peptide concentrations were reduced immediately after surgery (P < .0001), but were partly normalized at the time of follow-up (P < .0001). These changes were not accompanied by improvements in insulin sensitivity (Matsuda index). However, the oral disposition index revealed a significant recovery of β-cell function at the time of follow-up (P < .05). These findings demonstrate a capacity for recovery of glucose control after partial pancreatectomy and suggest that β-cell function can improve significantly over time even in adult humans.

Abstract
PURPOSE Delayed gastric emptying (DGE) is a leading cause of complication after pylorus-preserving pancreaticoduodenectomy (PPPD). Its incidence has been reported to range from 5 to 57%. We describe a modified reconstruction method, which resulted in a low rate of DGE. METHODS Between April 2003 and March 2008, we performed PPPD and reconstruction using an antecolic method in 118 consecutive patients. After PPPD, reconstruction was done using conventional Child procedure in 12 patients (PPPD group) and with the following modifications in the remaining 106 patients (PPPDR group): duodenojejunostomy was performed using the straight method and the jejunum was anastomosed with a 30° counterclockwise twist. We evaluated the incidence of DGE based on the grading system defined by the International Study Group of Pancreatic Surgery (ISGPS). RESULTS The PPPDR group had a lower incidence of DGE than the PPPD group (PPPD), occurring in 7 patients (7%) versus 4 patients (33%), respectively. However, the overall morbidity rates and postoperative hospital stays of the two groups did not differ significantly. CONCLUSIONS Straight stomach reconstruction with a twisted anastomosis could reduce the incidence of DGE after PPPD reconstruction.

Abstract
BACKGROUND Reflux esophagitis is a common complication following a distal gastrectomy. Increasingly, Roux-en-Y reconstruction has been used to prevent reflux esophagitis; however, marginal ulcer is a concern in patients with a Roux-en-Y reconstruction after distal gastrectomy. The effect of Roux-en-Y reconstruction on the development of reflux esophagitis and marginal ulcer after pancreaticoduodenectomy (PD) has not been studied. METHODS We retrospectively studied both reflux esophagitis and marginal ulcer after 371 PDs and analyzed the association with different methods of gastrointestinal reconstruction. RESULTS In a median follow-up time of 20 months, 40 (10.8%) of the 371 patients developed reflux esophagitis, 15 after 158 standard PD, and 25 after 213 pylorus-preserving pancreaticoduodenectomy (PPPD; P = 0.62). Cox regression model showed Roux-en-Y reconstruction was significantly inversely related to occurrence of reflux esophagitis in 158 patients after standard PD (P = 0.04) but not in 213 patients after PPPD (P = 0.24). Thirty-five of 371 studied patients developed marginal ulcer, 15 after standard PD and 20 after PPPD (P = 0.45). Multivariate analysis showed that Roux-en-Y reconstruction was the only significant predictor for marginal ulcer after PD (P = 0.02). CONCLUSIONS Our data support the use of Roux-en-Y reconstruction after standard PD but not after PPPD.

Abstract
BACKGROUND A high rate of mortality and morbidity has been associated with pancreaticoduodenectomy; the 5-year survival rate is 15% to 25% compared with 1% to 5% among those who did not have any cancer-directed treatment. Systemic rather than surgical complications cause the majority of perioperative deaths, so the anesthesiologist has a crucial role in the management of these patients. This work sought to evaluate an improved approach to perioperative pain management, postsurgical complications as well as outcomes. PATIENTS From 2002 to 2007, 40 patients underwent pancreaticoduodenectomy for pancreatic or periampullary cancer. The anesthesia protocol was standardized for postoperative pain control. Patients were randomly divided into two groups: 16 patients received an epidural analgesia with local anesthetics combined with opioids (T(9)-T(10); group A) and 24 had IV analgesia with morphine (group B). RESULTS Postoperative mortality was 2.5%. With regard to complications we observed 4 biliary fistulas, 2 pancreatic fistulas with spontaneous healing in one patient and death in the other as well as wound infections. Patients treated with epidural analgesia experienced better pain relief, compared with subjects receiving IV analgesia, which demonstrated a higher incidence of opioid-related adverse effects such as sedation and respiratory depression. CONCLUSION Adequate perioperative treatment included suitable nutritional support and pain management using loco-regional techniques, which seem to improve the surgical outcomes among pancreatic cancer patients.

Abstract
BACKGROUND Reinsertion of the distal common bile duct (CBD) into the pancreatic resection cavity during duodenum-preserving pancreatic head excision (DPPHE) may be an alternative option to Whipple resection or bilioenteric anastomosis when chronic pancreatitis is associated with CBD stenosis. METHODS Outcome in 82 patients with chronic pancreatitis who underwent DPPHE with CBD reinsertion was compared with that in 432 who had DPPHE without reinsertion and 50 who had a Whipple procedure or pylorus-preserving pancreatoduodenectomy (PPPD). RESULTS There were no deaths after DPPHE with CBD reinsertion, compared with four (0.9 per cent) after DPPHE without reinsertion and three (6 per cent) after classical resection. Overall morbidity rates were 30, 28.9 and 36 per cent respectively. Fifteen patients (18 per cent) who had DPPHE with CBD reinsertion developed a stricture at the reinsertion site, compared with a long-term stricture rate of 2.3 per cent (ten patients) after DPPHE without CBD reinsertion and 4 per cent (two patients) after PPPD/Whipple resection. CONCLUSION Although associated with a high incidence of anastomotic stricture, reinsertion of the CBD into the resection cavity as part of DPPHE can be used to preserve duodenal passage and offers an alternative to extended resection for chronic pancreatitis.

Abstract
OBJECTIVE Delayed gastric emptying (DGE) is the major morbidity after pylorus-preserving pancreaticoduodenectomy (PPPD). Gastroscintigraphy was used to characterize food distribution in the proximal and distal stomach during emptying. PATIENTS AND METHODS Between October 2000 and June 2003, 20 healthy volunteers and 23 PPPD patients underwent single-phase gastric emptying scintigraphy 14 days after surgery. Scintigraphic studies of the stomach were divided into proximal and distal regions, and the ratio of proximal to distal radiation counts (P/DR) was plotted. Momentary monitor-displayed images were compared to evaluate meal distribution during emptying. RESULTS There were 21 eligible patients, 12 without symptoms of DGE (sDGE-) and 9 with symptoms of DGE (sDGE+). In healthy volunteers the mean P/DR value was maintained at a level of > or = 2.5, and momentary images showed dilated proximal and constricted distal stomach throughout meal emptying. In both the solid and liquid phase tests, the average P/DR value for sDGE- patients was slightly lower than that for healthy volunteers, and momentary images showed early emptying of the solid meal. The mean P/DR value for sDGE+ patients was abnormally low and remained constant throughout the assessment. Momentary images showed significant dilatation of the distal stomach, with constant full size. The odds ratio for the change in P/DR per minute decreased after surgery, especially in sDGE+ patients, indicating a loss of contractility of the distal stomach. At the 6-month follow-up, the P/DR values exhibited a normal decreasing trend but were lower for sDGE+ patients than for healthy volunteers. CONCLUSIONS The P/DR curve provides new insight into normal and pathological gastric function. After surgery, temporary loss of contractility of the distal stomach causes symptoms of DGE.

Abstract
BACKGROUND Subtotal stomach preserving pancreaticoduodenectomy (SSPPD) is compared retrospectively with pylorus preserving pancreaticoduodenectomy (PPPD). METHODS During 2002-2005, 21 patients (13 female, 8 male) underwent SSPPD. The mean age was 64.3 (range 33-80). PPPD was performed for 12 patients after 1999. Days of hospital stay, operation time, operative blood loss, postoperative morbidity and mortality, days of nasogastric intubation, days until liquid diet, delayed gastric emptying, postoperative change of serum Albumin value, were compared between SSPPD and PPPD. Clinical characteristics (age, gender, benign, or malignant condition, presence of preoperative jaundice, preoperative value of serum Albumin) were analyzed in both procedures. RESULTS In comparison of clinical characteristics, all factors were similar between PPPD and SSPPD. There were also quite similar results in days of hospital stay, operation time, operative blood loss, postoperative morbidity and mortality. Days of nasogastric intubation, days until liquid diet in PPPD were significantly longer than those in SSPPD and the incidence of delayed gastric emptying in PPPD was significantly higher than that in SSPPD. Finally, PPPD and SSPPD postoperative change of serum Albumin value were statistically similar. CONCLUSIONS We consider SSPPD as one of the most favorable procedures in patients who undergo pancreaticoduodenectomy.

Abstract
The pylorus-preserving pancreatoduodenectomy (PPPD) has taken the place of the conventional Whipple pancreatoduodenectomy as the standard procedure for various periampullary disease. With recent advances in surgical techniques and improvements in perioperative management, the number of long-term survivors after PPPD is increasing. As a result, surgeons should pay more attention to the patients' postoperative gastrointestinal function, nutrition, and quality of life (QOL). Gastric stasis, which is a frequent complication during the early postoperative period after PPPD, prolongs the hospital stay and impairs the QOL in the intermediate term. Several possible pathogeneses for this gastric stasis have been postulated; however, the precise mechanism remains unclear. The gastric emptying function gradually recovers to the preoperative level by 6 months after PPPD. Pancreatic functions are likely to be maintained for at least 1 year after PPPD; however, in some cases, they tend to gradually deteriorate over time after the operation, depending on the type of pancreatic reconstruction or the preoperative condition of the pancreas. It is important to note that preoperative and postoperative pancreatic exocrine function strongly influence the postoperative outcome regarding such factors as pancreatic fistula, body weight maintenance, nutrition, and the QOL. The QOL, as assessed by questionnaire, normally returns to the preoperative level within 6 months after PPPD, and this correlates with the changes in gastrointestinal function and nutritional status. It still remains an unresolved question, however, whether the Billroth-I PPPD really leads to better long-term nutritional status, but worse early gastric emptying function, than the Billroth-II type of reconstruction.

Abstract
Pylorus-preserving pancreaticoduodenectomy (PPPD) is nowadays considered the treatment of choice for periampullary tumors, namely carcinoma of the head, neck, or uncinate process of the pancreas, the ampulla of Vater, distal common bile duct or carcinoma of the peri-Vaterian duodenum. Delayed gastric emptying (DGE) comprises one of the most troublesome complications of this procedure. A search of the literature using Pubmed/Medline was performed to identify clinical trials examining the incidence rate of DGE following standard Whipple pancreaticoduodenectomy (PD) vs PPPD. Additionally we performed a thorough in-depth analysis of the implicated pathomechanism underlying the occurrence of DGE after PPPD. In contrast to early studies, the majority of recently performed clinical trials demonstrated no significant association between the occurrence of DGE with either PD or PPPD. PD and PPPD procedures are equally effective operations regarding the postoperative occurrence of DGE. Further randomized trials are required to investigate the efficacy of a recently reported (but not yet tested in large-scale studies) modification, that is, PPPD with antecolic duodenojejunostomy.

Abstract
AIM: To clarify the innervation of the antro-pyloric region in humans from a clinico-anatomical perspective.
METHODS: The stomach, duodenum and surrounding structures were dissected in 10 cadavers, and immersed in a 10mg/L solution of alizarin red S in ethanol to stain the peripheral nerves. The distribution details were studied to confirm innervations in the above areas using a binocular microscope. Similarly, innervations in 10 Suncus murinus were examined using the method of whole-mount immunohistochemistry.
RESULTS: The innervation of the pyloric region in humans involved three routes: One arose from the anterior hepatic plexus via the route of the suprapyloric/supraduodenal branch of the right gastric artery; the second arose from the anterior and posterior gastric divisions, and the third originated from the posterior-lower region of the pyloric region, which passed via the infrapyloric artery or retroduodenal branches and was related to the gastroduodenal artery and right gastroepiploic artery. For Suncus murinus, results similar to those in humans were observed.
CONCLUSION: There are three routes of innervation of the pyloric region in humans, wherein the route of the right gastric artery is most important for preserving pyloric region innervation. Function will be preserved by more than 80% by preserving the artery in pylorus-preserving pancreaticoduodenectomy (PPPD). However, the route of the infrapyloric artery should not be disregarded. This route is related to several arteries (the right gastroepiploic and gastroduodenal arteries), and the preserving of these arteries is advantageous for preserving pyloric innervation in PPPD. Concurrently, the nerves of Latarjat also play an important role in maintaining innervation of the antro-pyloric region in PPPD. This is why pyloric function is not damaged in some patients when the right gastric artery is dissected or damaged in PPPD.

Abstract
Somatostatin inhibits gastroenteropancreatic exocrine secretion and is often used after pancreaticoduodenectomy to reduce pancreatic secretion to minimize tissue damage and pancreatic stump complications. Because our earlier clinical work saw a major increase in delayed gastric emptying (DGE) with somatostatin prophylaxis after pylorus-preserving pancreaticoduodenectomy (PPPD), this small-group study was designed to confirm or disprove that observation. From August 1997 to December 2000, a total of 23 post-PPPD patients were randomized to receive somatostatin prophylaxis [somatostain (+)] (n = 11) or not [somatostatin] (-) (n = 12). The incidence of DGE, scintographic solid-phase emptying results on day 14 postoperatively, and sequential fasting plasma motilin levels were compared, as motilin levels are related to both gastric motility and somatostatin levels. The somatostatin(+) group exhibited greatly increased patient complaints of DGE: 9 of 11 (82%) versus 3 of 12 (25%) in the somatostatin(-) group. Radiologic scintography showed somatostatin prophylaxis prolonged the half-time (T(1/2)) of solid-phase emptying: 144.5 +/- 51.4 minutes for somatostatin(+) versus 89.0 +/- 59.9 minutes for somatostatin(-) (p < 0.001). Comparing pre-PPPD and post-PPPD plasma motilin levels prior to somatostatin infusion, motilin decreased 80% in reaction to the surgery. For somatostatin(-) patients, motilin levels oscillated, or "rang," postoperatively, reaching a higher level on day 3, declined to a new record minimum on day 7, and by day 21 were 50% of the original and the slope of the recovery curve was increasing well. In somatostatin(+) patients the same ringing pattern was observed but decreased with motilin levels 30% to 70% lower than in the somatostatin(-) patients. By day 21 somatostatin(+) motilin levels were recovering but still only 20% original levels, and the slope of the recovery curve was not optimistic. On postoperative day 14 the plasma motilin levels (below approximately 6 bg/ml) correlated strongly with DGE for both groups. Despite the small sample size, the results indicated that (1) somatostatin prophylaxis significantly decreases fasting plasma motilin; (2) somatostatin prophylaxis produces lingering suppression of plasma motilin; (3) PPPD surgery itself significantly reduces fasting motilin levels with recovery to 50% normal at day 21; (4) the mechanism of somatostatin-induced DGE seems related to reduced fasting plasma motilin levels.

Abstract
OBJECTIVES Pylorus preserving pancreatoduodenectomy (PPPD) was introduced to achieve a better functional result compared with the conventional Kausch-Whipple procedure (PD). In PPPD, peripyloric and perigastric lymphatic tissue is not removed compared with PD. The aim of this prospective study was to identify the frequency of peripyloric and perigastric lymph node metastases in ductal adenocarcinoma of the pancreatic head (PC). METHODS Fifty specimens following Kausch-Whipple procedure including partial gastric resection for PC were analyzed for peripyloric and perigastric lymph node metastases by a standardized clearing technique. All lymph nodes of the specimens were counted, discriminating between those not removed ("group A") and those removed ("group B") in pylorus preserving resection of the pancreatic head. Additionally, the duodenal wall and paraduodenal tissue at a potential duodenal resection margin 2 cm distal of the pylorus were investigated histologically. RESULTS Three of the 50 specimens (6%) carried peripyloric lymph node metastases, whereas 32 of the 50 specimens (64%) contained lymph node metastases in total. Four of 362 group A and 90 of 748 group B lymph nodes showed metastatic spread of the carcinoma. The 4 lymph node metastases in group A could be identified exclusively in 88 peripyloric lymph nodes but in none of the 274 perigastric lymph nodes at the lesser or greater curvature. In 2 of the 3 patients with peripyloric lymph node metastases, these lymph nodes were the only lymph nodes with metastatic involvement in the entire specimen. In 1 specimen, a small tumor nest of less than 2 mm in diameter was detected at a distance of less than 1 mm to the pylorus, although pyloric involvement was not suspected intraoperatively. The potential PPPD resection margin of the duodenal wall was not infiltrated by intramural tumor spread in any specimen. CONCLUSION In a minority of 6%, PC metastasizes in peripyloric lymph nodes. Lymph nodes of the lesser and greater curvature of the stomach are not involved in patients with PC. Thus, we conclude by the data of this prospective study that the limited benefits of the extended lymph node dissection in a conventional Kausch-Whipple resection are far outweighed by the disadvantages construed by this procedure.

Abstract
Literature reports indicate that the incidence of delayed gastric emptying (DGE) is higher after pylorus-preserving pancreaticoduodenectomy (PPPD) than after conventional pancreaticoduodenectomy (CPD), but DGE is traditionally diagnosed from patient-reported subjective sensations. Our clinical radiological experience suggests higher rates for physiological DGE post-CPD. We therefore sought to quantify rates of subjective DGE (sDGE, based on patient complaint) verses objective DGE (oDGE, based on scintography) post-CPD and post-PPPD. Contractile motility of post-PPPD residual stomach was also studied. For 21 PPPD and 33 CPD patients between October 1997 and June 2000, sDGE and oDGE data were collected preoperatively, on postoperative day 14, and 6 months postoperatively, with cholescintography for pylorus ring competency on postoperative day 14. The incidence of sDGE was higher for PPPD (42%) than for CPD (15%) at 14 days, with zero sDGE for both at 6 months. The incidence oDGE was higher for CPD (91%) than for PPPD (76%) at 14 days, with a 6-month incidence of 4.7% in PPPD but approximately 33% for CPD. Solid-phase emptying in PPPD showed that residual stomach retained partial gastric emptying function at 14 days but not at 6 months. Cholescintography showed abnormal pylorus closure function in 2 of 21 PPPD patients but was not related to DGE. Literature reports of higher DGE incidence post-PPPD are true only for subjective symptoms. Radiological measurement of oDGE shows that both CPD and PPPD manifest approximately 80% incidence of DGE in the early postoperative period. At 6 months, approximately 33% of CPD show persistent oDGE. We concluded that (1) the concept of DGE should distinguish between subjective and objective symptoms; (2) loss of distal stomach mechanoreceptors in CPD reduces patients sensation of oDGE, producing "silent" DGE; (3) both CPD and PPPD have high and approximately equal rates oDGE; (4) the previously unnoticed silent oDGE in CPD may contribute to the higher rates of ulceration and related morbidity in association with CPD.

Abstract
Endocrine neoplasms only rarely occur at the ampulla of Vater, comprising mostly carcinoids and malignant carcinoids, as well as few cases of poorly differentiated endocrine carcinomas (small cell carcinomas). Only 105 cases are reported in the literature, most as single case reports. For many years, the neoplasms of the disseminated neuroendocrine cell system of the gastrointestinal tract have been subsumed as 'carcinoids'. Instead, in the latest World Health Organization (WHO) classification published in 2000, it is recommended to distinguish between (i) well-differentiated endocrine tumors (carcinoids); (ii) well-differentiated endocrine carcinomas (malignant carcinoids); and (iii) poorly differentiated endocrine carcinomas (small cell carcinomas). Patients with carcinoid tumors of the ampulla of Vater are very often free of clinical and laboratory findings that belong to the carcinoid syndrome. Approximately 26% of all patients with carcinoid tumor reported in the literature had neurofibromatosis. Besides endoscopic retrograde cholangiopancreatography, endosonography, computed tomography or magnetic resonance imaging may complete the staging approach of this tumor. The Kausch-Whipple procedure or pylorus-preserving pancreaticoduodenectomy is considered the treatment of choice for ampullary, well-differentiated carcinoids >2.0 cm and for ampullary neuroendocrine carcinomas. However, it should be considered that long-term survival of patients with ampullary carcinoids is also reported after local tumor excision (5-year survival rate of 90%). The dilemma is that the differentiation of neuroendocrine tumors cannot be assessed intraoperatively in most cases. Therefore, considering that the 5-year survival rate in patients with neuroendocrine carcinomas of the ampulla of Vater is very low without radical resection, neuroendocrine tumors of the ampulla of Vater without definite histological differentiation should undergo extended surgery.

Abstract
Patients undergoing pylorus-preserving pancreatoduodenenectomy (PPPD) have a risk of up to 50% for developing delayed gastric emptying (DGE) in the early postoperative course. From 1994 to August 2002, a total of 204 patients underwent PPPD for pancreatic or periampullary cancer (50%), chronic pancreatitis (42%), and other indications (8%). Retrocolic end-to-side duodenojejunostomy was performed below the mesocolon. DGE was defined by the inability to tolerate a regular diet after day 10 (DGE10) or day 14 (DGE14) postoperatively, as well as the need for a nasogastric tube at or beyond day 10 (DGE10GT). Postoperative morbidity was 38%, 30-day mortality was 2.9%, and median postoperative length of stay was 15 days. DGE occurred in 14.7% (DGE10), 5.9% (DGE14), and 6.4% (DGE10GT), respectively. After further exclusion of 21 patients (10.3%) with major complications and no possible oral intake (because of death, reoperation, or mechanical ventilation), the frequencies of DGE10, DGE14, and DGE10GT in the remaining group of 183 patients were 9%, 2%, and 2%, respectively. Multivariate analysis revealed postoperative complications (P<0.001), the presence of portalvenous hypertension (P<0.01), and tumors as indications for surgery (P<0.01) as independent risk factors for DGE10. The overall incidence of DGE was low after PPPD. In those patients experiencing DGE, however, other postoperative complications were the most important factor associated with its occurrence.

Abstract
Pancreatoduodenectomy (PD) has become a routine procedure. Recent series report perioperative mortality rates of 5% or less, moderate morbidity, and even improved long-term survival. Nevertheless, being one of the most complex abdominal operations, a certain number of surgical procedures (i.e., personal caseload) seems essential for acceptable results. The objectives of this retrospective study were to evaluate whether PD can be safely performed as a teaching operation, and if the personal caseload of the senior surgeon affects morbidity and mortality. A series of 128 consecutive PDs carried out at a large academic teaching hospital were analyzed. The 49 operations performed by 11 residents of the surgical department as teaching operations under supervision of an experienced (senior) surgeon (ES) were compared with operations performed by an ES (group 2, n = 79). Three patients died from non-procedure-related causes (two in group 1). Eleven patients of group 2 had to be reoperated, in contrast to three in group 1 (NS). The total number of complications and number of pancreatic fistulas were comparable in the two groups. Surgeons performing less than one PD per year had significantly more complications. Under direct supervision of an experienced surgeon PD can be performed safely as a teaching operation. A caseload of at least one resection per year seems necessary for consistently good results.

Abstract
A solid pseudopapillary neoplasm (SPN) is an extremely rare tumour of the pancreas that frequently occurs in young females and is mostly benign. SPN is a low-grade malignant tumour that may evolve years before symptoms start. However, the pathogenesis of this tumour remains unclear and there are no adequate reports of long-term results to evaluate the management and the long-term surgical control. We describe a new case of SPN with a 10-year follow-up, and review the world literature that accounts for approximately 322 cases. Moreover, a review of the current management and surgical tendencies in the treatment of SPN is considered. An SPN pancreatic tumour occurred in a 24-year-old female who complained of episodic mild abdominal pain sustained by a palpable epigastric mass. The tumour mass was detected by ultrasound and computer tomography and was localised at the tail of the pancreas adherent to the spleen. The preoperative diagnosis was uncertain and en-block distal pancreatectomy and splenectomy were performed. The size of the mass which weighed 300 g was 11 x 12 x 8 cm, and the tumour was strictly adherent and invaded the splenic hilum. Histologic examination confirmed a complete resection of the primary SPN that locally invaded spleen. The postoperative period was uneventful and after a 10-year follow-up the patient is free of symptoms. SPN should be considered in the differential diagnosis of large pancreatic masses, especially in young females. Radical resection, where technically feasible, should be considered the therapy of choice as it is a safe and effective control of the disease.

Abstract
OBJECTIVE To show that residual pancreatitis delays gastric emptying, the authors used surgical specimens and studied gastric stasis after pylorus-preserving pancreaticoduodenectomy (PPPD). SUMMARY BACKGROUND DATA Delayed gastric emptying is a leading cause of complications after PPPD, occurring in 30% of patients. The pathogenesis of delayed gastric emptying remains unclear. METHODS Surgical specimens of the pancreas from 25 patients undergoing PPPD and pancreaticogastrostomy were collected and examined by microscopy according to progressive pancreatic fibrosis and divided into three groups: no fibrosis, periductal fibrosis, and intralobular fibrosis. The authors then measured gastric output from the nasogastric tube, pancreatic output from the pancreatic tube, and the time until patients tolerated a solid diet. RESULTS Pancreatic juice output was significantly related to the degree of pathologic findings, and gastric output was inversely related to them. A significant prolongation of postoperative solid diet tolerance correlated with increased pancreatic fibrosis and gastric fluid production. CONCLUSIONS Pancreatic fibrosis and increased gastric fluid production correlate with delayed gastric emptying after PPPD with pancreaticogastrostomy.

Abstract
STUDY AIM To evaluate the influence of a pylorus-preserving on the morbidity and prognosis of patient with pancreaticoduodenectomy for adenocarcinoma of pancreas. PATIENTS AND METHODS Between 1985 and 1999, 183 patients were operated on for pancreatic adenocarcinoma. Among them, 63 patients (40 men, mean age 63 years, range 41-77 years) had curative resection and were included in this retrospective study. They were classified according to the type of resection. In the group I, the procedure included a pylorus-preserving pancreaticoduodenectomy (n = 35). In the group II, the procedure included polar inferior gastrectomy (n = 28). The prognosis was compared. Parameters for comparison were rate of local recurrence, rate of metastatic evolution and duration of survival. RESULTS The operative length and mortality rate (group I: 0%, group II: 3%), general (p = 0.37) and specific morbidity (p = 0.30), frequency of delayed gastric emptying were similar in the 2 groups (group I: 20%, group II: 35%, p = 0.88). The duration of naso-gastic aspiration was shorter in the group I (6 days vs 8, p = 0.01). The prognosis was the same in the 2 groups (metastasis: group I: 39%, group II: 56%, p = 0.12, local recurrence: group I: 58%, group II: 43%, p = 0.09, mean survival: group I: 18 months, group II: 19 months, p = 0.77). CONCLUSION These results suggest that pylorus preserving pancreatoduodenectomy could be performed for patients with adenocarcinoma of the head of the pancreas and does not compromise survival.

Abstract
BACKGROUND Pancreatic fistula (PF) and delayed gastric emptying (DGE) is a leading cause of morbidity after pylorus-preserving pancreaticoduodenectomy (PPPD), occurring in 20% to 40% of patients. METHODS Between August 1994 and March 2000, 30 consecutive patients underwent our modified PPPD and were evaluated on their incidence of PF and DGE. The major modification of our technique was an antecolic reconstruction and setting the transverse colon between pancreaticogastrostomy and duodenojejunostomy RESULTS Operative time and blood loss were, respectively, 5.2+/-0.93 hours and 730+/-330 mL. Hospital mortality was 0%. Postoperative morbidity was 23%. Delayed gastric emptying and pancreatic fistula were observed in 3 (10%) and 0 (0%) of 30 patients. Nasogastric suction was required for 7+/-2 days, and a solid diet could be tolerated on postoperative day 11+/-4. CONCLUSIONS The results show that our reconstruction can minimize DGE.

Abstract
Our purpose was to determine whether pylorus-preservation in the Imanaga (PpPDI) method minimizes postoperative impairment of gastrointestinal function. Nine patients who had undergone PpPDI (postoperative years: 5.7 +/- 2.6) and nine patients who had undergone conventional Imanaga pancreatoduodenectomy (PDI) (postoperative years: 6.8 +/- 2.0) were evaluated for symptoms, nutritional parameters, and physiologic function of the biliary tract and residual stomach using gastric emptying and hepatobiliary scintigraphy. The body weight recovered to 99.3% +/- 3.8% of pre-illness body weight in PpPDI, showing a significantly better recovery than in patients after the PDI procedure (91.0% +/- 6.4%, P < 0.05). The mean gastric emptying half-time (GET1/2) in the upright position after PDI was significantly shorter (42.3 min) than after PpPDI (80.8 min, P < 0.05). Mixture of food with bile was conserved better in the PpPDI group than in the PDI group. In the long term, the pylorus-preserving Imanaga-type procedure minimizes disruption of gastric function and asynchrony between ingested food and bile.

Abstract
BACKGROUND Delayed gastric emptying is one of the most frequent postoperative complications after Whipple resection. In the present study we evaluated the role of enteral nutrition in the development of delayed gastric emptying after Whipple resection. PATIENTS AND METHODS Between January 1996 and June 1998, 64 patients (30 female, 34 male) underwent a classic (n = 27) or pylorus-preserving (n = 37) Whipple resection. Two patients were excluded; 30 patients received enteral and 32 patients received no-enteral nutrition. RESULTS Delayed gastric emptying occurred significantly more in patients with enteral (17 of 30, 57%) than in patients with no-enteral nutrition (5 of 32, 16%) (P <0.01). Consequently, patients in the enteral nutrition group had a nasogastric tube for a significantly (P<0.01) longer period and had a significantly (P<0.01) longer hospital stay than patients in the no-enteral nutrition group. There were no differences in the frequency of occurrence of other postoperative complications between patients with enteral and no-enteral nutrition. CONCLUSION In patients undergoing a Whipple resection, enteral nutrition is associated with a higher frequency of delayed gastric emptying with no advantages regarding other postoperative complications and should therefore be restricted to specific indications.

Abstract
The past century has been nearly all of the growth in knowledge about the anatomy and pathophysiology associated with cancers of the pancreas and surrounding biliary structures. Through advances in imaging technology, endoscopic practice, improvement in surgical technique and perioperative care, anesthesia advances, and a better appreciation for the usefulness of adjuvant chemotherapy and radiation therapy, physicians can offer patients some hope for long-term survival and a better quality of life when they are faced with these devastating tumors. Although surgical intervention is the "last best hope" for these patients, advances in the nonoperative disciplines will be required for substantial further improvement in patient outcomes.

Abstract
OBJECTIVE To compare the short- and long-term results of pancreaticoduodenectomy with pylorus preservation (PPPD) or with antrectomy (Whipple procedure) in the treatment of selected patients with chronic pancreatitis. BACKGROUND PPPD may be preferred over Whipple because of its purported nutritional advantages and the reduced likelihood of postgastrectomy syndromes. METHODS A retrospective review was performed of 72 consecutive patients undergoing pancreaticoduodenectomy for chronic pancreatitis between 1991 and 1997. RESULTS PPPD was performed in 39 patients and Whipple in 33. The two patient populations had similar characteristics. Short-term complications included (PPPD vs. Whipple): pancreatic or biliary fistulas (5.1% vs. 15%), delayed gastric emptying (33% vs. 12%), cholangitis (2.6% vs. 6.1%), and death (0 vs. 3%). Delayed gastric emptying was not associated with other complications and resulted in longer hospital stays for PPPD than for Whipple patients (15 vs. 12 days). The duration of follow-up averaged 41 +/- 24 months. Long-term weight status was similar, with body-mass indices of 22.1 and 22.9 after PPPD and Whipple, respectively. Postoperative enzyme supplementation (63% vs. 77%) and new-onset diabetes (10% vs. 12%) did not differ significantly between the PPPD and Whipple groups. Dumping, bile gastritis, or peptic ulcer disease occurred in three patients after PPPD and in three after Whipple. Complete or partial pain relief was attained in 60% and 70% of patients after PPPD and Whipple, respectively. Multivariate analysis of preoperative variables revealed that site-specific pathology in the head of the pancreas was the only independent factor associated with successful pain relief after pancreatic resection. CONCLUSION PPPD results in higher frequencies of postoperative delayed gastric emptying compared with the Whipple procedure. Both operations achieve comparable long-term nutritional results, cause new insulin dependence in surprisingly few patients, and provide equivalent pain relief to 65% of selected patients. Patients with disproportionate pathology in the head of the pancreas have a higher likelihood of successful pain relief.

Abstract
BACKGROUND It has been proposed that adenomas of the papilla of Vater are precursors of adenocarcinomas. Duodenoscopy with ERCP and forceps biopsies have substantially improved the morphologic exploration of the major duodenal papilla. Yet there is little and contradictory information as to the diagnostic accuracy of endoscopic biopsies in tumors of the papilla. Moreover, after endoscopic sphincterotomy data on the diagnostic impact of endoscopic biopsies from the papilla are scarce and, in most cases, retrospectively obtained. Thus, the aim of the present prospective and histopathologically controlled study was to assess the diagnostic accuracy of endoscopic biopsies taken from tumors of the papilla before and after sphincterotomy. PATIENTS AND METHODS Forty patients with tumors of the papilla of Vater were included in the study. In each case, a comparison was made between endoscopic forceps biopsy diagnoses prior to and following sphincterotomy and the definitive histological diagnosis after surgical tumor resection. RESULTS Resected tumors were diagnosed histomorphologically as follows: 19 adenocarcinomas (47%), 6 tubular adenomas (15%), 7 villous adenomas (17%), 7 inflammatory non-neoplastic lesions (pseudotumors) (17%), and one adenomyoma (2%). Overall accuracy for preoperative histopathological diagnosis was 62% (25 of 40, 95% CI: 47%-76%) prior to sphincterotomy while it was 70% (28 of 40, 95% CI: 55%-81%) following the procedure. Regarding adenocarcinomas, sensitivity was found to be 21% (4 of 19, 95% CI: 8%-43%) prior to and 37% (7 of 19, 95% CI: 19%-58%) after sphincterotomy while specificity was 100% at both times. CONCLUSIONS Endoscopic forceps biopsies do not allow for reliable preoperative diagnosis of tumors of the papilla of Vater.

Abstract
BACKGROUND Pancreaticoduodenectomy, with either gastrectomy (Whipple procedure) or pylorus-preserving pancreaticoduodenectomy (PPPD), is a complex procedure. Technical diversity, variation and sampling bias exist among surgeons. Previous reports comparing these two procedures are retrospective and not randomized. These factors should be considered seriously and eliminated in comparisons between the two procedures. METHODS From August 1994 to August 1997, a prospective randomized comparison was conducted between the Whipple procedure and PPPD performed by the same surgeon with the same approach and same anastomotic fashion for periampullary cancer. After exclusion of seven patients, 31 patients were eligible for the study, 16 receiving PPPD and 15 a Whipple procedure. No significant difference in the age, sex distribution, tumour localization or staging was noted between the two groups. RESULTS One operative death after PPPD and no operative death after the Whipple procedure resulted in a 3 per cent mortality rate in the 31 patients. Median duration of the Whipple operation was 235 (range 195-305) min, with a median blood loss of 500 (range 230-3100) ml and a median blood transfusion of 0 (range 0-10) units. In the patients who had PPPD, median operating time was 230 (range 170-275) min, median blood loss was 350 (range 100-1200) ml and median blood transfusion was 0 (range 0-4) units. There were two minor leaks from the pancreaticojejunostomy after the Whipple procedure and no leakage after PPPD, resulting in 6 per cent minor leakage in 31 patients. These outcomes were not significantly different. Delayed gastric emptying was observed more frequently after PPPD (six of 16 patients) than after the Whipple procedure (one of 15 patients), with marginal significance (P = 0.08, two-sided Fisher's exact test). CONCLUSION In this prospective randomized study, both PPPD and the Whipple procedure were associated with low mortality and operative morbidity rates. There was no significant difference between PPPD and Whipple resection in terms of operative mortality and morbidity, operating time, blood loss and blood transfusion. PPPD was associated with more frequent delayed gastric emptying, although study of more patients is needed to confirm this.

Abstract
OBJECTIVE This single-institution experience retrospectively reviews the outcomes of patients undergoing reexploration for periampullary carcinoma at a high-volume center. SUMMARY BACKGROUND DATA Many patients are referred to tertiary centers with periampullary carcinoma after their tumors were deemed unresectable at previous laparotomy. In carefully selected patients, tumor resection is often possible; however, the perioperative results and long-term outcome have not been well defined. METHODS From November 1991 through December 1997, 78 patients who underwent previous exploratory laparotomy and/or palliative surgery for suspected periampullary carcinoma underwent reexploration. The operative outcome, resectability rate, pathology, and long-term survival rate were compared with 690 concurrent patients who had not undergone previous exploratory surgery. RESULTS Fifty-two of the 78 patients (67%) undergoing reexploration underwent successful resection by pancreaticoduodenectomy; the remaining 26 patients (34%) were deemed to have unresectable disease. Compared with the 690 patients who had not undergone recent related surgery, the patients in the reoperative group were similar with respect to gender, race, and resectability rate but were significantly younger. The distribution of periampullary cancers by site in the reoperative group undergoing pancreaticoduodenectomy (n = 52) was 60%, 19%, 15%, and 6% for pancreatic, ampullary, distal bile duct, and duodenal tumors, respectively. These figures were similar to the 65%, 14%, 16% and 5% for resectable periampullary cancers found in the primary surgery group (n = 460). Intraoperative blood loss and transfusion requirements did not differ between the two groups. However, the mean operative time was 7.4 hours in the reoperative group, significantly longer than in the control group. On pathologic examination, reoperative patients had smaller tumors, and the percentage of patients with positive lymph nodes in the resection specimen was significantly less. The incidence of positive margins was similar between the two groups. Postoperative lengths of stay, complication rates, and perioperative mortality rates were not higher in reoperative patients. The long-term survival rate was similar between the two resected groups, with a median survival of 24 months in the reoperative group and 20 months in those without previous exploration. CONCLUSIONS These data demonstrate that patients undergoing reoperation for periampullary carcinoma have similar resectability, perioperative morbidity and mortality, and long-term survival rates as patients undergoing initial exploration. The results suggest that selected patients considered to have unresectable disease at previous surgery should undergo restaging and reexploration at specialized high-volume centers.

Abstract
BACKGROUND An adenoma-carcinoma sequence also applies to adenomas of the major duodenal papilla. Therefore accurate preoperative diagnosis and tumor staging are essential to select the appropriate patients for adequate treatment. In a prospective, histopathologically controlled study of tumors of the main duodenal papilla, the preoperative diagnostic value of ultrasound (US) catheter probes applied during endoscopic retrograde cholangiopancreatography (ERCP) was investigated. METHODS Intraductal US was compared with conventional endoscopic ultrasonography (EUS) and computed tomography (CT). In 27 consecutive patients with benign polypoid tumors of the major duodenal papilla (n = 12) and carcinomas of the papilla (n = 15), respectively, the value of these imaging procedures in determining tumor visualization, tumor diagnosis and tumor staging according to the TNM classification was assessed. Every patient underwent surgical resection; histopathologic evaluation of resected specimens served as the reference standard. RESULTS Intraductal US was significantly superior to EUS and CT in terms of tumor visualization (100% vs 59.3% vs 29.6%, respectively). Sensitivity and specificity rates for intraductal US and EUS were 100% versus 62.5% and 75% versus 50%, respectively. Overall accuracy rate in tumor diagnosis for intraductal US (88.9%; 24 of 27) was significantly (p = 0.05) superior to EUS (56.3%; 9 of 16). The latter did not depict 4 adenomas and 7 carcinomas. Neither intraductal US nor EUS is suitable for detection of distant metastases. CONCLUSION Intraductal US appears to be the most effective imaging method in visualizing, diagnosing and staging tumors of the major duodenal papilla. Combining ERCP with catheter probe sonography offers a new diagnostic modality that has some potential advantages for local staging of small tumors of the main duodenal papilla. Consequently, minimally invasive techniques for resection of seemingly benign tumors of the papilla or, even more so, of small carcinomas should preferably be based on intraductal US.

Abstract
OBJECTIVE To study the recovery course of gastric emptying after Billroth I pylorus-preserving pancreatoduodenectomy (PPPD) and therapeutic effects of cisapride. METHODS To examine gastric emptying, acetaminophen was given, admixed in a pasty liquid meal, to 16 patients undergoing PPPD before surgery and at 1, 3, 6, 9, and 12 months after surgery. Cisapride was given orally to 10 patients before they received the acetaminophen regimen. Electrogastrography was performed at 2 weeks to 1 month after surgery in eight patients and at 6 to 12 months after surgery in seven patients. RESULTS Gastric emptying was delayed but returned to the preoperative level by 6 months after surgery. Pretreatment with cisapride accelerated gastric emptying during months 1 to 6 but not during months 6 to 12 after surgery. Electrogastrography frequently showed tachygastria 2 weeks to 1 month after surgery, but seldom 6 to 12 months after surgery. CONCLUSIONS After Billroth I PPPD, gastric emptying is delayed but recovers by 6 months after surgery. Tachygastria may play a part in the pathogenesis of delayed gastric emptying, but it can be treated with cisapride.

Abstract
This review analyses the current state of knowledge and understanding concerning the optimum treatment and therapeutic management of patients who suffer from pancreatic cancer. It outlines recent advances in scientific understanding and assesses their potential future value to clinicians in confronting this disease. Despite a significant expansion in scientific knowledge relating to factors underlying the early development of pancreatic carcinoma, the clinician continues to be restricted to a severely limited therapeutic armoury for this disease. Local therapies (surgery and radiation) are inevitably of limited value in the face of a disease that is normally encountered at a stage where metastasis is already highly developed. Despite such limitations, however, surgery performed in specialist units may be of value for 10-20% of patients, with a 5-year survival rate in such units of between 10 and 24%. This may be improved even further by appropriate use of adjuvant treatment. The advanced stage of the disease when normally encountered emphasizes the potential value of systemic treatment in this therapeutic area. Unfortunately systemic treatment (chemotherapy) has been found to be ineffective to date in significantly extending survival, with a low rate and duration of remission being identified in most trials. The challenge for both the health service and the pharmaceutical industry is to harness recent and future developments in scientific knowledge to the practical benefit of clinicians. Where cure is possible it should be vigorously pursued; where it is not, in this field above all others, clinicians have a duty of care. To achieve this it is necessary to abandon the therapeutic nihilism that has characterized the attitudes of clinicians towards this disease in the past. It is time that such nihilism was replaced by a recognition of the challenges and the opportunities available to clinicians in enhancing the quantity and quality of life available to patients. The dictum of 'curing whenever possible but caring always' should be the future therapeutic philosophy used to guide clinicians in this important and rapidly changing therapeutic area.

Abstract
The case of a 91-yr-old man who had a tumor of the pancreas head successfully resected is reported. He was admitted to our hospital because of obstructive jaundice, and then percutaneous transhepatic biliary drainage (PTBD) was performed. Cholangiography via PTBD tube showed marked stenosis of the bile duct in the head of the pancreas. Endoscopic retrograde pancreatography (ERP) showed obstruction of the main pancreatic duct in the head of the pancreas, and carcinoma in the head of the pancreas was diagnosed. Abdominal angiography showed stenosis of the celiac trunk caused by compression from the median arcuate ligament, but no tumor stain or encasement in the pancreas was detected. Because the patient had lived an extremely healthy life and had no serious concurrent disease before admission, laparotomy was performed. The tumor in the head of the pancreas was about 2 cm in diameter and restricted inside the pancreas. Pylorus-preserving pancreatoduodenectomy (PpPD) with regional lymph node dissection was performed. The tumor was 1.5 cm in its maximal diameter, and histopathologically was diagnosed as an invasive ductal carcinoma of the pancreas with moderately differentiated tubular adenocarcinoma. The patient had an uneventful postoperative course and now, 3 yr after surgery, he is doing very well and leading a normal daily life.
