Ann Surg Oncol 2024; 31:4637-4653. [PMID: 38578553 PMCID: PMC11164799 DOI: 10.1245/s10434-024-15222-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 03/09/2024] [Indexed: 04/06/2024]
Abstract
BACKGROUND Pancreatoduodenectomy (PD) has a considerable surgical risk for complications and late metabolic morbidity. Parenchyma-sparing resection of benign tumors has the potential to cure patients associated with reduced procedure-related short- and long-term complications. MATERIALS AND METHODS Pubmed, Embase, and Cochrane libraries were searched for studies reporting surgery-related complications following PD and duodenum-preserving total (DPPHRt) or partial (DPPHRp) pancreatic head resection for benign tumors. A total of 38 cohort studies that included data from 1262 patients were analyzed. In total, 729 patients underwent DPPHR and 533 PD. RESULTS Concordance between preoperative diagnosis of benign tumors and final histopathology was 90.57% for DPPHR. Cystic and neuroendocrine neoplasms (PNETs) and periampullary tumors (PATs) were observed in 497, 89, and 31 patients, respectively. In total, 34 of 161 (21.1%) patients with intraepithelial papillar mucinous neoplasm exhibited severe dysplasia in the final histopathology. The meta-analysis, when comparing DPPHRt and PD, revealed in-hospital mortality of 1/362 (0.26%) and 8/547 (1.46%) patients, respectively [OR 0.48 (95% CI 0.15-1.58); p = 0.21], and frequency of reoperation of 3.26 % and 6.75%, respectively [OR 0.52 (95% CI 0.28-0.96); p = 0.04]. After a follow-up of 45.8 ± 26.6 months, 14/340 patients with intraductal papillary mucinous neoplasms/mucinous cystic neoplasms (IPMN/MCN, 4.11%) and 2/89 patients with PNET (2.24%) exhibited tumor recurrence. Local recurrence at the resection margin and reoccurrence of tumor growth in the remnant pancreas was comparable after DPPHR or PD [OR 0.94 (95% CI 0.178-5.34); p = 0.96]. CONCLUSIONS DPPHR for benign, premalignant neoplasms provides a cure for patients with low risk of tumor recurrence and significantly fewer early surgery-related complications compared with PD. DPPHR has the potential to replace PD for benign, premalignant cystic and neuroendocrine neoplasms.

Recurrent cholangitis in patients with a non-stenotic hepaticojejunostomy: incidence and risk factors. HPB (Oxford) 2024; 26:558-564. [PMID: 38245491 DOI: 10.1016/j.hpb.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 12/27/2023] [Accepted: 01/05/2024] [Indexed: 01/22/2024]
Abstract
BACKGROUND Cholangitis is a well-known complication after hepaticojejunostomy (HJ), which is mainly caused by a stenotic anastomosis. However, the rate of cholangitis in patients with a non-stenotic (i.e. patent) HJ is unknown. We aimed to evaluate the incidence and risk factors of recurrent cholangitis in patients with a non-stenotic HJ. METHODS This single-center retrospective cohort study included all consecutive patients who had undergone hepatobiliary or pancreatic (HPB) surgery requiring HJ (2015-2022). Primary outcome was recurrent non-stenotic cholangitis, risk factors for recurrent non-stenotic cholangitis were identified using logistic regression. RESULTS Overall, 835 patients with a HJ were included of whom 31/698 (4.4%) patients developed recurrent cholangitis with a non-stenotic HJ during a median follow-up of 34 months (IQR 22-50) and 98/796 (12.3%) patients developed a symptomatic HJ stenosis. These 31 patients experienced 205 cholangitis episodes, median 7.0 (IQR 3.8-8.8) per patient, and 71/205 (34.6%) cholangitis episodes required hospitalization. Male sex (aOR 3.17 (95% CI: 1.34-7.49)) and benign disease (aOR 2.97, 95% CI 1.40-6.33) were identified as risk factors for recurrent cholangitis in non-stenotic HJ in both univariate and multivariable analysis. CONCLUSION This study shows that 4% of patients developed recurrent cholangitis without an underlying HJ stenosis.

Real-time fluorescence imaging with indocyanine green during laparoscopic duodenum-preserving pancreatic head resection. Pancreatology 2024; 24:130-136. [PMID: 38016861 DOI: 10.1016/j.pan.2023.11.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 11/12/2023] [Accepted: 11/13/2023] [Indexed: 11/30/2023]
Abstract
BACKGROUND Laparoscopic duodenum-preserving pancreatic head resection (LDPPHR) is a surgical method used to treat benign and low-grade malignant pancreatic head tumors. This study aimed to determine the protective effect of common bile duct in LDPPHR using indocyanine green (ICG) fluorescence imaging. METHODS A retrospective analysis of 30 patients treated with LDPPHR at the Second Affiliated Hospital of Nanchang University between January 2015 and November 2022 was performed. Patients were divided into two groups based on ICG use: ICG and non-ICG. RESULTS Thirty patients received LDPPHR, 11 males and 19 females, and the age was 50.50 (M (IQR)) years (range: 19-76 years). LDPPHR was successfully performed in 27 (90 %) patients, LPD was performed in 1 (3 %) patient, and laparotomy conversion was performed in 2 (7 %) patients. One patient (3 %) died 21 days after surgery. The incidence of intraoperative bile duct injury in the ICG group was lower than that in the non-ICG group (10 % vs 60 %, P = 0.009), and the operation time in the ICG group was shorter than that in the non-ICG group (311.9 ± 14.97 vs 338.05 ± 18.75 min, P < 0.05). Postoperative pancreatic fistula occurred in 16 patients (53 %), including 10 with biochemical leakage (62.5 %), four with grade B (25 %), and two with grade C (12.5 %). Postoperative bile leakage occurred in four patients (13 %). CONCLUSIONS The ICG fluorescence imaging technology in LDPPHR helps protect the integrity of the common bile duct and reduce the occurrence of intraoperative bile duct injury, postoperative bile leakage, and bile duct stenosis.

Ann Gastroenterol Surg 2024; 8:8-20. [PMID: 38250689 PMCID: PMC10797825 DOI: 10.1002/ags3.12746] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 09/06/2023] [Accepted: 09/24/2023] [Indexed: 01/23/2024] Open
Abstract
In this review article, we focus on recent papers on organ-preserving pancreatectomy procedures published since 2010. When comparing central pancreatectomy (CP) and distal pancreatectomy (DP), most studies have concluded that the CP group exhibited significantly lower incidence of new-onset diabetes or diabetes exacerbation than the DP group postoperatively. However, because of increased incidence of morbidities such as pancreatic fistula, the surgeon faces a considerable trade-off between increased short-term morbidity and long-term preservation of endocrine function. When the outcomes of two types of spleen-preserving DP (Kimura and Warshaw procedures) are compared, most studies mentioned the low incidence of postoperative gastric varices and splenic infarction with the Kimura procedure. Although there are several reports regarding the effect of spleen preservation on prevention of postoperative infections, no report on the contribution of spleen preservation to the prevention of overwhelming post-splenectomy infection is seen. The advantages of duodenum-preserving pancreatic head resection (DPPHR) concerning endocrine and exocrine functions continue to be subjects of discussion, mainly due to the limited number of institutions that have adopted this approach; however, DPPHR should be presented as an option for patients due to its low incidence of postoperative cholangitis. Organ-preserving pancreatectomy requires meticulous surgical techniques, and postoperative complications may increase with this surgery compared with standard pancreatectomy, which may be influenced by the surgeon's skill and the surgical facility where the procedure is performed. Nonetheless, this technique has significant long-term advantages in terms of endocrine and exocrine functions and its wider adoption in the future is expected.

Abstract
BACKGROUND Pancreatic benign, cystic, and neuroendocrine neoplasms are increasingly detected and recommended for surgical treatment. In multiorgan resection pancreatoduodenectomy or parenchyma-sparing, local extirpation is a challenge for decision-making regarding surgery-related early and late postoperative morbidity. METHODS PubMed, Embase, and Cochrane Libraries were searched for studies reporting early surgery-related complications following pancreatoduodenectomy (PD) and duodenum-preserving total (DPPHRt) or partial (DPPHRp) pancreatic head resection for benign tumors. Thirty-four cohort studies comprising data from 1099 patients were analyzed. In total, 654 patients underwent DPPHR and 445 patients PD for benign tumors. This review and meta-analysis does not need ethical approval. RESULTS Comparing DPPHRt and PD, the need for blood transfusion (OR 0.20, 95% CI 0.10-0.41, p<0.01), re-intervention for serious surgery-related complications (OR 0.48, 95% CI 0.31-0.73, p<0.001), and re-operation for severe complications (OR 0.50, 95% CI 0.26-0.95, p=0.04) were significantly less frequent following DPPHRt. Pancreatic fistula B+C (19.0 to 15.3%, p=0.99) and biliary fistula (6.3 to 4.3%; p=0.33) were in the same range following PD and DPPHRt. In-hospital mortality after DPPHRt was one of 350 patients (0.28%) and after PD eight of 445 patients (1.79%) (OR 0.32, 95% CI 0.10-1.09, p=0.07). Following DPPHRp, there was no mortality among the 192 patients. CONCLUSION DPPHR for benign pancreatic tumors is associated with significantly fewer surgery-related, serious, and severe postoperative complications and lower in-hospital mortality compared to PD. Tailored use of DPPHRt or DPPHRp contributes to a reduction of surgery-related complications. DPPHR has the potential to replace PD for benign tumors and premalignant cystic and neuroendocrine neoplasms of the pancreatic head.

Abstract
ObjectivesIn this systemic review and network meta-analysis, we investigated pancreaticoduodenectomy (PD), pylorus-preserving pancreaticoduodenectomy (PPPD), and different modifications of duodenum-preserving pancreatic head resection (DPPHR) to evaluate the efficacy of different surgical procedures.MethodsA systemic search of six databases was conducted to identify studies comparing PD, PPPD, and DPPHR for treating pancreatic head benign and low-grade malignant lesions. Meta-analyses and network meta-analyses were performed to compare different surgical procedures.ResultsA total of 44 studies were enrolled in the final synthesis. Three categories of a total of 29 indexes were investigated. The DPPHR group had better working ability, physical status, less loss of body weight, and less postoperative discomfort than the Whipple group, while both groups had no differences in quality of life (QoL), pain scale scores, and other 11 indexes. Network meta-analysis of a single procedure found that DPPHR had a larger probability of best performance in seven of eight analyzed indexes than PD or PPPD.ConclusionDPPHR and PD/PPPD have equal effects on improving QoL and pain relief, while PD/PPPD has more severe symptoms and more complications after surgery. PD, PPPD, and DPPHR procedures exhibit different strengths in treating pancreatic head benign and low-grade malignant lesions.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier: CRD42022342427.

Abstract
Background Postoperative cholangitis is a late complication of pancreaticoduodenectomy (PD). This study aimed to elucidate the pathogenesis of post-PD cholangitis (PPDC) and explore its optimal treatment. Methods We retrospectively analyzed 210 patients who underwent PD at our institute between 2009 and 2018. Patients who underwent follow-up for less than 1 year or had cholangitis caused by cancer recurrence were excluded from the analysis. Diagnostic criteria for cholangitis and its severity were determined based on the classification of acute cholangitis provided by the 2018 Tokyo Guidelines (TG18). Results PPDC occurred in 19 (11%) of the 176 included patients. Of these 19 patients, nine experienced more than one episode of cholangitis (total episodes, 36). For 14 patients (74%), the first episode of PPDC occurred within two years after surgery. Based on the TG18, 21 episodes were mild and 15 episodes were moderate; none were severe. Blood culture test results were positive for 16 of 24 episodes. Most patients were hospitalized and treated with intravenous antibiotics (median, seven days). The blood test values improved promptly after treatment was started. Four patients with recurrent cholangitis underwent endoscopic examination, and three of them had anastomotic stenosis of the hepaticojejunostomy. The univariate and multivariate analyses did not indicate any significant predictive factors for PPDC development. Conclusion Mild and moderate PPDC occurred and improved with short-term antimicrobial treatment. Temporary reflux into the intrahepatic bile ducts may have been the cause of PPDC while anastomotic stenosis may be involved in recurrent cases.

Abstract
OBJECTIVE To assess metabolic dysfunctions and steatohepatosis after standard and local pancreatic resections for benign and premalignant neoplasms. SUMMARY OF BACKGROUND DATA Duodenopancreatectomy, hemipancreatectomy, and parenchyma-sparing, limited pancreatic resections are currently in use for nonmalignant tumors. METHODS Medline, Embase, and Cochrane libraries were searched for studies reporting measured data of metabolic functions following PD, pancreatic left resection (PLR), duodenum-sparing pancreatic head resection (DPPHR), pancreatic middle segment resection (PMSR), and tumor enucleation (TEN). Forty cohort studies comprising data of 2729 patients were eligible. RESULTS PD for benign tumor was associated in 46 of 327 patients (14.1%) with postoperative new onset of diabetes mellitus (pNODM) and in 109 of 243 patients (44.9%) with postoperative new onset of pancreatic exocrine insufficiency measured after a mean follow-up of 32 months. The meta-analysis displayed pNODM following PD in 32 of 204 patients (15.7%) and in 10 of 200 patients (5%) after DPPHR [P < 0.01; OR: 0.33; (95%-CI: 0.15-0.22)]. PEI was found in 77 of 174 patients following PD (44.3%) and in 7 of 104 patients (6.7%) following DPPHR (P < 0.01;OR: 0.15; 95%-CI: 0.07-0.32). pNODM following PLR was reported in 107 of 459 patients (23.3%) and following PMSR 23 of 412 patients (5.6%) (P < 0.01; OR: 0.20; 95%-CI: 0.12-0.32). Postoperative new onset of pancreatic exocrine insufficiency was found in 17% following PLR and in 8% following PMSR (P < 0.01). pNODM following PPPD and tumor enucleation was observed in 19.7% and 5.7% (P < 0.03) of patients, respectively. Following PD/PPPD, 145 of 608 patients (23.8%) developed a nonalcoholic fatty liver disease after a mean follow-up of 30.4 months. Steatohepatosis following DPPHR developed in 2 of 66 (3%) significantly lower than following PPPD (P < 0.01). CONCLUSION Standard pancreatic resections for benign tumor carry a considerable high risk for a new onset of diabetes, pancreatic exocrine insufficiency and following PD for steatohepatosis. Parenchyma-sparing, local resections are associated with low grade metabolic dysfunctions.

Abstract
Aim. To study the early postoperative outcomes of duodenum-preserving total pancreatic head resections in benign, premalignant tumors of the pancreatic head and chronic pancreatitis complicated by duodenal dystrophy in comparison with the results of pylorus-preserving pancreaticoduodenectomy. Materials and methods. From 2006 to 2019, 54 patients underwent duodenum-preserving total pancreatic head resection for chronic pancreatitis complicated by duodenal dystrophy, benign or premalignant tumors of the pancreatic head. At the same time, in 25 cases, the operation was performed in an isolated version, in 29 – with a resection of the duodenum. As a comparison group, we used data from 89 patients who underwent pyloruspreserving pancreaticoduodenectomy during the same period. Results. Compared to pancreaticoduodenectomy, duodenum-preserving total pancreatic head resection exhibits significantly longer times for surgery (420 and 310 minutes, respectively). There was no statistically significant difference in the volume of intraoperative blood loss. There are no differences between groups in hospital morbidity (the frequency of pancreatic fistulas, delayed gastric emptying, bile leakage and post-resection bleeding). The frequency of postoperative complications for Clavien-Dindo III and higher did not differ significantly in the groups. There is no hospital mortality after duodenum-preserving total pancreatic head resection; three patients died after pancreatoduodenectomy. Conclusion. Early postoperative outcomes following duodenum-preserving total pancreatic head resection and pylorus-preserving pancreaticoduodenectomy are comparable. However, to develop a full-fledged concept of surgical treatment of pancreatic head benign, premalignant neoplasms and chronic pancreatitis with duodenal dystrophy, it is necessary to analyze the long-term outcomes of treatment.

Arteriovenous malformation in the pancreatic head initially mimicking a hypervascular mass treated with duodenum-preserving pancreatic head resection: a case report. Surg Case Rep 2020; 6:301. [PMID: 33259015 PMCID: PMC7708544 DOI: 10.1186/s40792-020-01075-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Accepted: 11/18/2020] [Indexed: 01/08/2023] Open
Abstract
Background The mainstay treatment for arteriovenous malformation in the pancreatic head (Ph-AVM) is standard pancreatectomy, especially pancreaticoduodenectomy (PD), or interventional endovascular treatment. We report the first case of Ph-AVM treated with duodenum-preserving pancreatic head resection (DPPHR) performed to preserve the periampullary organs. Case presentation A 59-year-old man presenting with back pain underwent contrast-enhanced computed tomography followed by angiography of the anterior superior pancreaticoduodenal artery. He was diagnosed with Ph-AVM and indicated for DPPHR with preservation of the periampullary organs; Ph-AVM’s benign nature seldom requires lymph node dissection. During the operation, the right colon was mobilized and the omental bursa was released to expose the periampullary structures. The pancreas was transected just above the superior mesenteric vein. The inferior pancreaticoduodenal artery and papillary arteries branching from the posterior superior pancreaticoduodenal artery were carefully preserved to maintain the blood flow to the lower bile duct and papilla of Vater. The remnant pancreas was reconstructed with pancreaticogastrostomy using the modified Blumgart method. Pathological examination of the resected specimen revealed an irregular course of the arteries and veins concomitant with marked dilation throughout the pancreatic head. The patient was pathologically diagnosed with Ph-AVM. He developed hematemesis caused by a rupture of the pseudoaneurysm on postoperative day 20 and underwent coil embolization. A bilio-enteric fistula and stenosis of the common bile duct were found and treated by placement of an endoscopic biliary stent. At the 8-month follow-up, the Ph-AVM had not recurred. Conclusions Compared to PD, DPPHR confers the clinical benefit of preserving the periampullary organs, although further studies are needed to confirm this. Therefore, the choice of this procedure should be based on the surgical morbidities and long-term outcome of the patient.

Abstract
BACKGROUND /ObjectivesThe aim of this study was to clarify the oncological outcomes of patients with intraductal papillary mucinous neoplasm (IPMN) who underwent limited resection (LR). METHODS This retrospective study analyzed the data of 110 patients with IPMN. Patients with IPMN without a history of pancreatitis who had neither tumor infiltration nor regional lymph node swelling on imaging findings underwent LR. We assessed the oncological outcomes of LR for patients with IPMN by comparing the surgical outcomes of LR and standard resection. RESULTS LR was performed in 50 patients (45.5%), including duodenum-preserving pancreatic head resection (n = 31), middle-pancreatectomy (n = 12), spleen-preserving distal pancreatectomy (n = 3), total parenchymal pancreatectomy (n = 3), and partial resection (n = 1). In the LR group, 18 patients had postoperative complications of Clavien-Dindo classification ≥ IIIa. After histopathological examination, the presence of high-grade dysplasia (HGD) and invasive carcinoma (IC) were observed in nine and three patients, respectively, in the LR group, and eight and 22 patients, respectively, in the standard resection group. There was a significant difference in the histopathological diagnosis of IC between the two groups (p < 0.001). Finally, in the LR group, postoperative recurrences occurred in three patients, and the 5-, 10-, and 15-year disease-specific survival rates were all 97.0%. CONCLUSIONS For patients with IPMN judged to have no infiltrating lesions based on the detailed imaging examination, LR is acceptable and may be considered as an alternative to standard resection.

Abstract
BACKGROUND Cholangitis is a serious biliary complication following biliary-enteric anastomosis (BEA). However, the rate of cholangitis in the postoperative period and its associated risk factors are inconclusive. The objective of this systematic review and meta-analysis was to assess the onset and risk factors of cholangitis after biliary-enteric reconstruction in literature. METHODS MEDLINE, EMBASE, and Cochrane databases were searched systematically to identify studies reporting about cholangitis following biliary-enteric anastomosis. Meta-analyses were performed for risk factors using random effects model with odds ratio (OR) and 95% confidence interval (95 %CI) as effect measures. Study quality was assessed by the MINORS (methodological index for non-randomized studies) criteria. RESULTS 28 studies involving 6904 patients were included in the study. The pooled rate for postoperative cholangitis (POC) was 10% (95 %CI: 8 %-13%) with studies reporting about an early- and late-onset of cholangitis. Male sex (OR 2.08; 95 %CI: 1.33-3.24; P = 0.001), postoperative hepatolithiasis (OR 137.19; 95 %CI: 29.00-648.97; P < 0.001) and postoperative anastomotic stricture (OR 178.29; 95 %CI: 68.64-463.11; P < 0.001) were associated with a higher risk of a late-onset of POC with a pooled rate of 8% (95 %CI: 6 %-11%) after a median time interval of 12 months. The quality of the included studies was low to moderate. CONCLUSION Cholangitis is a frequent complication after BEA. Consensus definition and prospective trials are required to assess optimal therapeutic strategies. We proposed a standardized definition and grading of POC to enable comparisons between future studies.

Abstract
BACKGROUND Metabolic dysfunctions after pancreatoduodenectomy (PD) need to be considered when pancreatic head resection is likely to lead to long-term survival. METHODS Medline, Embase and Cochrane Library were searched for studies reporting measured data of metabolic function after PD and duodenum-sparing total pancreatic head resection (DPPHR). Data from 23 cohort studies comprising 1019 patients were eligible; 594 and 910 patients were involved in systematic review and meta-analysis, respectively. RESULTS The cumulative incidence of postoperative new onset of diabetes mellitus (pNODM) after PD for benign tumors was 46 of 321 patients (14%) measured after follow-up of in mean 36 months postoperatively. New onset of postoperative exocrine insufficiency (PEI) was exhibited by 91 of 209 patients (44%) after PD for benign tumors measured in mean 23 months postoperatively. The meta-analysis indicated pNODM after PD for benign tumor in 32 of 208 patients (15%) and in 10 of 178 patients (6%) after DPPHR (p = 0.007; OR 3.01; (95%CI:1.39-6.49)). PEI was exhibited by 80 of 178 patients (45%) after PD and by 6 of 88 patients (7%) after DPPHR (p < 0.001). GI hormones measured in 194 patients revealed postoperatively a significant impairment of integrated responses of gastrin, motilin, insulin, secretin, PP and GIP (p < 0.050-0.001) after PD. Fasting and stimulated levels of GLP-1 and glucagon levels displayed a significant increase (p < 0.020/p < 0.030). Following DPPHR, responses of gastrin, motilin, secretin and CCK displayed no change compared to preoperative levels. CONCLUSIONS After PD, duodenectomy, rather than pancreatic head resection is the main cause for long-term persisting, postoperative new onset of DM and PEI.

Abstract
BACKGROUND In 1972, Beger et al.1 first described duodenum-preserving pancreatic head resection (DPPHR) for patients with severe chronic pancreatitis. Then DPPHR also was proved capable of providing comparable long-term oncologic outcomes in the setting of benign or low-grade malignant tumors.2 As an organ-preserving procedure, DPPHR preserves the integrity of the digestive tract and improves the patient's quality of life compared with pancreaticoduodenectomy (PD),3 although DPPHR is more technically challenging, especially in protecting the bile duct and the pancreaticoduodenal vascular arch.4,5 The indocyanine green (ICG)-enhanced fluorescence imaging system in laparoscopic surgery can identify the biliary and vascular anatomy clearly to ensure a safe cholecystectomy and an adequate vascular supply for colectomy or nephrectomy.6 Nevertheless, to date, no report has described ICG-enhanced fluorescence in laparoscopic duodenum-preserving pancreatic head resection (LDPPHR). This article describes the technique of LDPPHR using a video of a real-time ICG fluorescence imaging system. METHODS A 29-year-old woman received a diagnosis of chronic pancreatitis and an inflammatory mass in the head of the pancreas. A computed tomography (CT) scan showed atrophy of the pancreas, dilation of the main pancreatic duct, and heterogeneous enhancement of the pancreatic head parenchyma (Fig. 1). Her other preoperative examination results were normal except for high blood sugar. To avoid an extended PD for this young patient, LDPPHR was performed. The patient was placed in supine position with her two legs apart. The observing trocar (10 mm) was located at the inferior umbilicus. Four trocars (two 5-mm trocars and two 12-mm trocars) were distributed symmetrically at the midclavicular line and anterior axillary line. Another 5-mm trocar located at the subxiphoid was used for traction of the stomach with a rubber band. Before the operation, ICG (5 mg) was injected intravenously from the elbow vein. The gastrocolic ligament was opened, and the hepatic flexure of the colon was taken down to explore the head of the pancreas without making a Kocher's maneuver. After hanging of the distal stomach with a rubber band, both the right gastroepiploic vein and Henle's trunk were dissected. The number 8a lymph node was dissected for intraoperative rapid frozen pathology. A post-pancreatic neck tunnel was built, and the pancreatic neck was transected with an ultrasonic scalpel. The main pancreatic duct was identified and transected with cold scissors. The superior mesenteric vein (SMV) was hung with another rubber band and retracted to the left. The uncinate process of the pancreas was retracted to the right, and subcapsular dissection was performed, with particular attention paid to protection of the anterior inferior pancreaticoduodenal artery (AIPDA), the posterior inferior pancreaticoduodenal artery (PIPDA), and their branches that go into the duodenum. Then the gastroduodenal artery (GDA) was identified, and the anterosuperior pancreatic duodenal artery (ASPDA) was dissected. The upper part of the pancreatic head was separated to expose the common bile duct (CBD) with the help of real-time ICG fluorescence imaging (Fig. 2). The pancreas was dissected from the left edge of the duodenum and the right and ventral edges of the CBD. The posterosuperior pancreatic duodenal artery (PSPDA) was identified at the dorsal edge of the CBD. The PSPDA and its branches going into the distal CBD as well as the ampulla of Vater were carefully preserved. The proximal side of the main and accessory pancreatic duct was identified and sutured. Pancreatic anastomosis was performed using the technique of Bing's anastomosis.7 Fig. 1 Enhanced computed tomography (CT) scan showing atrophy of the pancreas, dilatation of the main pancreatic duct, and heterogeneous enhancement of the pancreatic head parenchyma Fig. 2 The common bile duct was separated and exposed from the head to the tail by the assistance of the real-time indocyanine green (ICG)-enhanced fluorescence imaging system RESULTS: The operation time was 251 min, and the estimated blood loss was 150 ml. The postoperative course was uneventful, with a hospital stay of 13 days. From February 2019 to November 2019, LDPPHR was used by the authors to manage 24 cases, including chronic pancreatitis (6 cases), pancreatic intraductal papillary mucinous tumors (6 cases), pancreatic neuroendocrine tumors (4 cases), pancreatic solid pseudopapillary tumors (4 cases), serous cystadenoma (3 cases), and mucinous cystadenoma (1 case). CONCLUSIONS Indocyanine green-enhanced fluorescence in laparoscopic duodenum-preserving pancreatic head resection was safe and may offer a benefit for maintaining the integrity of the biliary system.

Abstract
BACKGROUND It is technical challenging to perform laparoscopic duodenum-preserving pancreatic head resection (LDPPHR). Only a few case reports and case series of LDPPHR are available in the literature. MATERIALS AND METHODS From February 2019 to November 2019, 24 cases of LDPPHR were carried out in the Department of Pancreas Surgery, West China Hospital, Sichuan University. Data were prospectively collected in terms of demographic characteristics (age, gender, BMI, and pathological diagnosis), intraoperative variables (operative time, estimated blood loss, transfusion, pancreatic texture, and diameter of main pancreatic duct), and post-operative variables (time for oral intake, post-operative hospital stay, and complications). RESULTS Nine male patients and fifteen female patients were included in this study. The median age of these patients was 43 years. All patients underwent duodenum-preserving total pancreatic head resection laparoscopically. The median operative time was 255 min. The median estimated blood loss was 200 ml. One patient required blood transfusion. The median post-operative hospital stay was 10 days. Three patients suffered from biliary fistula. Eleven patients (45.8%) suffered from pancreatic fistula; however, only one patient (4.2%) suffered from grade B pancreatic fistula. No patient suffered from grade C pancreatic fistula. One patient with chronic pancreatitis required re-operation for jejunal anastomotic bleeding on the first post-operative day. No patient suffered from gastroparesis, duodenal necrosis, or abdominal bleeding. The 30-day mortality was 0. CONCLUSION LDPPHR is safe and feasible. Real-time indocyanine green fluorescence imaging may help prevent bile duct injury and bile leakage.

Abstract
BACKGROUND Outcomes of proximal parenchymal pancreatectomy (PPP) as compared to pancreatoduodenectomy (PD) have not been reported. The aim of this study was to describe the short- and long-term outcomes of patients with low-grade pancreatic head lesions who underwent PPP or PD. METHODS Patients who underwent PPP or PD for low-grade lesions between 2009 and 2017 were included. Operative factors including postoperative complications and nutritional indicators during the first-year postoperatively were compared. RESULTS A total of 13 and 14 patients underwent PPP and PD respectively. The PPP group demonstrated significantly less intraoperative blood loss and shorter postoperative hospital stay than the PD group. No significant differences were noted in the incidence of postoperative complications between the two groups. Nutritional indices were significantly better in the PPP group at 3 months post-surgery, but these nutritional indices were not significantly different at 6 months and 1-year. None of 12 patients who underwent PPP and did not require biliary resection developed postoperative cholangitis. None of the 12 PPP patients without preoperative diabetes developed impaired glucose tolerance after surgery. DISCUSSION The complication rate of PPP is equivalent to that of PD. PPP demonstrated better short-term nutritional status than PD. Moreover, preservation of the total duodenum and bile duct may reduce the risk of developing postoperative diabetes and cholangitis.

[PMID: 31168245 PMCID: PMC6527627 DOI: 10.1007/s13193-019-00901-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2018] [Revised: 01/07/2019] [Accepted: 03/03/2019] [Indexed: 12/31/2022] Open
Abstract
Pancreatic exocrine insufficiency (PEI) is a common long-term complication after pancreaticoduodenectomy (PD) and is observed in 23-80% of patients. As the postoperative mortality after PD has substantially decreased, it warrants more attention on the diagnosis and treatment of functional long-term consequences after PD. These include PEI and endocrine insufficiency that can result in significant nutritional impairment and often adversely impacts quality of life (QOL) of the patient. A PubMed search was performed for articles using key words "pancreatic exocrine insufficiency"; "pancreaticoduodenectomy"; "quality of life after pancreaticoduodenectomy"; "stool elastase"; "direct, indirect tests for pancreatic exocrine insufficiency"; "pancreatic enzyme replacement therapy." Relevant studies were shortlisted and analyzed. This review summarizes relevant studies addressing PEI following PD. We also discuss functional changes after PD, risk factors and predictive factors for postoperative PEI, clinical symptoms, direct and indirect tests for estimation of PEI, pancreatic enzyme replacement therapy (PERT), and QOL after pancreatic resection for malignancy. It was found that significant PEI occurs in most patients following PD. Fecal elastase 1 is an easy indirect test and should be performed routinely in both symptomatic and asymptomatic patients after PD. PERT should be considered in every patient after PD with the aim to improve the QOL and perhaps even their long time survival.

Abstract
Pancreatoduodenectomy is the most common surgery for benign tumors of the pancreatic head and chronic pancreatitis. However, advanced resection and unsatisfactory quality of life in long-term period call into question the propriety of this procedure for benign tumors of the pancreatic head and chronic pancreatitis. Duodenum-sparing proximal pancreatectomy is the current approach. The review is devoted to the main techniques of duodenum-sparing pancreatectomy, outcomes of these procedures and their role in pancreatic surgery.

Abstract
BACKGROUND Parenchyma-sparing, local pancreatic head resection, but not pancreaticoduodenectomy (PD) preserves tissue and maintains the pancreatic metabolic functions. METHODS PubMed/Medline, Embase, and Cochrane library collections were systematically searched. Twenty-six cohort studies with 523 cumulative patients, who underwent duodenum-sparing pancreatic head resection (DPPHR), were retrieved. The meta-analysis was based on 14 controlled studies. RESULTS In total, 338 patients suffered cystic neoplasms and 59 PNETs, IPMN-174, MCN-43 and SPN-23 patients. Eighty-one patients (15.5%) histo-pathologically displayed a low-malignant tumor, of which 27 were carcinoma in-situ. Tumor recurrence was observed after a mean follow-up of 47.1 months in 11 patients. In-hospital and late mortality after DPPHR was 0.6% and 1.7%, respectively. The meta-analysis was based on 318 DPPHR compared to 404 PD patients. DPPHR was performed for premalignant neoplasm and PNET in 164 and 46 patients, and PD in 181 and 46 patients, respectively. Events of recurrence displayed no statistically significant difference between the DPPHR and PD groups. CONCLUSION DPPHR is associated with oncologically complete tumor resection for patients suffering premalignant IPMN, MCN, or SPN and for low-risk cancer.

Abstract
BACKGROUND The impact of pylorus preserving procedures (PP) on total pancreatectomy with islet autotransplantation (TPIAT) has not been examined. This study aimed to investigate the clinical impact of the PP on TPIAT. METHODS The Baylor Simmons Transplant Institute database was queried to identify seventy-three patients who underwent TPIAT from 2006 to 2014. All patients were investigated in postoperative complications, long-term nutritional status, and graft function. RESULTS Patients with PP did not face worse outcomes in terms of delayed gastric emptying and length of hospital stay. Also, nutritional status and metabolic outcome, such as body weight, serum albumin level, serum vitamin level, HbA1c level, graft survival rate and insulin independent rate, were similar between both groups. CONCLUSIONS Clinical results including the graft function indicated that patients undergoing TPIAT with PP did not amplify surgical complications such as delayed gastric emptying and showed no significant advantage of nutrition and metabolic outcome.

Abstract
BACKGROUND Parenchyma-sparing local extirpation of benign tumors of the pancreatic head provides the potential benefits of preservation of functional tissue and low postoperative morbidity. METHODS Medline/PubMed, Embase, and Cochrane library databases were surveyed for studies performing limited resection of the pancreatic head and resection of a segment of the duodenum and common bile duct or preservation of the duodenum and common bile duct (CBD). The systematic analysis included 27 cohort studies that reported on limited pancreatic head resections for benign tumors. In a subgroup analysis, 12 of the cohort studies were additionally evaluated to compare the postoperative morbidity after total head resection including duodenal segment resection (DPPHR-S) and total head resection conserving duodenum and CBD (DPPHR-T). RESULTS Three hundred thirty-nine of a total of 503 patients (67.4%) underwent total head resections. One hundred forty-seven patients (29.2%) of them underwent segmental resection of the duodenum and CBD (DPPHR-S) and 192 patients (38.2%) underwent preservation of duodenum and CBD. One hundred sixty-four patients experienced partial head resection (32.6%). The final histological diagnosis revealed in 338 of 503 patients (67.2%) cystic neoplasms, 53 patients (10.3%) neuroendocrine tumors, and 20 patients (4.0%) low-risk periampullary carcinomas. Severe postoperative complications occurred in 62 of 490 patients (12.7%), pancreatic fistula B + C in 40 of 295 patients (13.6%), resurgery was experienced in 2.7%, and delayed gastric emptying in 12.3%. The 90-day mortality was 0.4%. The subgroup analysis comparing 143 DPPHR-S patients with 95 DPPHR-T patients showed that the respective rates of procedure-related biliary complications were 0.7% (1 of 143 patients) versus 8.4% (8 of 95 patients) (p ≤ 0.0032), and rates of duodenal complications were 0 versus 6.3% (6 of 95 patients) (p ≤ 0.0037). DPPHR-S was associated with a higher rate of delay of gastric emptying compared to DPPHR-T (18.9 vs. 2.1%, p ≤ 0.0001). CONCLUSION Parenchyma-sparing, limited head resection for benign tumors preserves functional pancreatic and duodenal tissue and carries in terms of fistula B + C rate, resurgery, rehospitalization, and 90-day mortality a low risk of postoperative complications. A subgroup analysis exhibited after total pancreatic head resection that preserves the duodenum and CBD an association with a significant increase in procedure-related biliary and duodenal complications compared to total head resection combined with resection of the periampullary segment of the duodenum and resection of the intrapancreatic CBD.

Abstract
BACKGROUND Limited surgical procedures for benign cystic neoplasms and endocrine tumours of the pancreas have the potential advantage of pancreatic tissue sparing compared to standard oncological resections. METHODS Searching PubMed/MedLine, Embase and Cochrane Library identified 86 full papers: 25 reporting on enucleation (EN), 38 on central pancreatectomy (CP) and 23 on duodenum-preserving total/partial pancreatic head resection (DPPHRt/p). The results are based on analysis of data of 838, 912 and 431 patients for EN, CP and DPPHRt/s, respectively. RESULTS The indication for EN for cystic neoplasms and neuro-endocrine tumours to EN was 20.5 and 73 %; for CP 62.9 and 31 %; and for DPPHRt/p 69.6 and 10.2%, respectively. The estimated mean tumour sizes were in EN-group 2.4 cm, in CP-group 2.9 cm and in DPPHRt/p-group 3.1 cm (DPPHRt/p vs EN, p = 0.035). Postoperative severe complications developed after EN, CP and DPPHRt/p in 9.6, 16.8 and 11.5% of patients; pancreatic fistula in 36.7, 35.2 and 20.1%; and reoperation was required in 4.7, 6.5 and 1.8 %, respectively. Hospital mortality after EN was 0.95 %; after CP 0.72%; and after DPPHRt/p 0.49%. Compared to EN and CP, DPPHRt/p exhibited significant lower frequency of reoperation (p = 0.029, p < 0.001) and lower rate of fistula (p < 0.001; p = 0.001). CONCLUSION EN, CP and DPPHRt/p applied for benign tumours are associated with low surgery-related early postoperative morbidity, a very low hospital mortality and the advantages of conservation of pancreatic functions. However, the level of evidence for EN and CP compared to standard oncological resections appears presently low. There is a high level of evidence from prospective controlled trials regarding the significant maintenance of exocrine and endocrine pancreatic functions after DPPHRt/p compared to pancreato-duodenectomy.

Abstract
BACKGROUND Potential benefits of local extirpation of benign pancreatic head tumors are tissue conservation of pancreas, stomach, duodenum and common bile duct (CBD) and maintenance of pancreatic functions. METHODS Medline/PubMed, Embase and Cochrane Library databases were searched to identify studies applying duodenum-preserving total or partial pancreatic-head resection (DPPHRt/p) and reporting short- and long-term outcomes. Twenty-four studies, including 416 patients who underwent DPPHRt/p, were identified for systematic analysis. The meta-analysis was based on 10 prospective controlled and 4 retrospective controlled cohort studies, comparing 293 DPPHRt/p resections with 372 pancreato-duodenectomies (PD). RESULTS, SYSTEMATIC ANALYSIS Of 416 patients, 75.7% underwent total and 24.3% partial head resection, while 47.1% included segmentectomy of duodenum and CBD. The most common pathology was cystic neoplasm (65.8%) and endocrine tumors (13.4%). The frequencies of severe postoperative complications of 8.8%, pancreatic fistula of 19.2%, re-operation of 1.7% and hospital mortality of 0.48%, indicate a low level of early post-operative complications. META-ANALYSIS DPPHRt/p significantly preserved the level of exocrine (IV = -0.67, 95% CI -0.98 to -0.35, p = 0.0001) and endocrine (IV = 18.20, fixed, 95% CI -0.92 to 25.48, p = 0.0001) pancreatic functions compared to PD when the pre- and postoperative functional status in both groups are analyzed. There were no significant differences between DPPHRt/p and PD in frequency of pancreatic fistula, delayed gastric emptying or hospital mortality. CONCLUSION DPPHRt/p for benign neoplasms and neuro-endocrine tumors of the pancreatic head is associated with a low level of early-postoperative complications and a better conservation of exocrine and endocrine functions.

Abstract
BACKGROUND The recent evolution of limited local operative procedures for benign pancreatic lesions shifted surgical treatment options to the application of local techniques, although major resections of pancreatic head and left resection are still the standard. OBJECTIVES To evaluate the level of evidence of tumour enucleation (EN), pancreatic middle segment resection (PMSR) and duodenum preserving total/subtotal pancreatic head resection (DPPHRt/s), we focus based on present knowledge on indication to surgical treatment evaluating the questions, when and how to operate. RESULTS Tumour enucleation is recommended for all symptomatic neuro-endocrine tumours with size up to 2-3 cm and non-adherence to pancreatic main-ducts. EN has been applied predominantly in neuro-endocrine tumours and less frequently in cystic neoplasms. 20% of enucleation are performed as minimal invasive laparascopic procedure. Surgery related severe post-operative complications with the need of re-intervention are observed in about 11%, pancreatic fistula in 33%. The major advantage of EN are low procedure related early post-operative morbidity and a very low hospital mortality. PMSR is applied in two thirds for symptomatic cystic neoplasm and in one third for neuro-endocrine tumours. The high level of 33% pancreatic fistula and severe post-operative complications of 18% is related to management of proximal pancreatic stump. DPPHRt/s is used in 70% for symptomatic cystic neoplasms, for lesions with risk for malignancy and in less than 10% for neuro-endocrine tumours. DPPHRt with segment resection of peripapillary duodenum and intra-pancreatic common bile duct has been applied in one third of patients and in two thirds by complete preservation of duodenum and common bile duct. The level of evidence for EN and PMSR is low because of retrospective data evaluation and absence of RCT results. For DPPHR, 7 prospective, controlled studies underline the advantages compared to partial pancreaticoduodenectomy. CONCLUSION The application of tumour enucleation, pancreatic middle segment resection and duodenum preserving subtotal or total pancreatic head resection are associated with low level surgery related early post-operative complications and a very low hospital mortality. The major advantage of the limited procedures is preservation of exo- and endocrine pancreatic functions.

Abstract
OBJECTIVE This study aimed to compare the body composition, dietary intake and serum levels of vitamins and minerals, and exocrine pancreatic function in patients late after pancreaticoduodenectomy (PD) and healthy subjects. METHODS Fifteen patients (PD group) who had undergone PD over 1 year before the study and 15 health volunteers (control group) were included in the study. All volunteers underwent dietary intake evaluation, body composition, laboratory data, exocrine pancreatic function by elastase-1, and carbon (C )-labeled triglycerides in breath tests. The PD group subjects also underwent upper gastrointestinal endoscopy and small intestinal bacterial overgrowth analysis. RESULTS Nutrient intake was adequate, and there were no differences in body mass index and mineral serum levels between the groups. The PD group showed lower serum levels of retinol, α-tocopherol, and ascorbic acid. Small intestinal bacterial overgrowth occurred in 39% of the patients. Fecal elastase-1 was lower in the PD group. The PD group had a higher C peak time; the cumulative label C recovery in 7 hours was similar in both groups. CONCLUSIONS Fecal elastase-1 decreased, and the excretion of C in breath was similar to healthy controls. Although the data point toward an adaptation in the absorptive capacity of fats, A, C, and E hypovitaminosis indicate that some absorptive insufficiency persists late after PD.

Abstract
Cystic neoplasms of the pancreas are being detected and surgically treated increasingly more frequently. Intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN) are primary benign lesions; however, the 5-year risk for malignant transformation has been estimated to be 63 % and 15 %, respectively. Surgical extirpation of a benign cystic tumor of the pancreas is a cancer preventive measure. The duodenum-preserving total pancreatic head resection technique (DPPHRt) is being used more frequently for cystic neoplasms of the pancreatic head. The complete resection of the pancreatic head can be applied as a duodenum-preserving technique or with segmental resection of the peripapillary duodenum. Borderline lesions, carcinoma in situ or T1N0 cancer of the papilla and the peripapillary common bile duct are also considered to be indications for segmental resection of the peripapillary duodenum. A literature search for cystic neoplastic lesions and DPPHRt revealed the most frequent indications to be IPMN, MCN and SCA lesions and 28 % suffered from a cystic neoplasm with carcinoma in situ or a peripapillary malignoma. The hospital mortality rate was 0.52 %. Compared to the Whipple type resection the DPPHRt exhibits significant benefits with respect to a low risk for early postoperative complications and a low hospital mortality rate of < 1 %. Exocrine and endocrine pancreatic functions after DPPHR are not impaired compared to the Whipple type resection.

Abstract
Backgrounds/Aims With development of imaging techniques, pancreatic tumors are being diagnosed more frequently. Applying the standard surgical procedures for pancreatic head tumors, such as pancreaticoduodenectomy and pylorus-preserving pancreaticoduodenectomy may seem too extensive for benign or low-grade malignant pancreas head tumors. Duodenum-preserving pancreatic head resection (DPPHR) has been safely performed in patients with chronic pancreatitis. Recently, DPPHR has been used as a limited surgical procedure to remove benign or low-grade malignant pancreatic head lesions. This study is aimed to evaluate the results of DPPHR in benign or low-grade malignant tumors. Methods Between 2004 and 2012, six patients underwent DPPHR due to benign or low-grade malignant pancreas tumor. We performed this retrospective analysis based on the medical records. Results Five of six patients were diagnosed as intraductal papillary mucinous neoplasms. Remaining one patient was diagnosed as solid pseudopapillary neoplasm. The median age of patients was 60.3 (27-75) years, and the median follow-up period was 24 months. The operation time, blood loss and length of stay were 442.5 minutes, 680 ml and 19.2 days, respectively. There was no mortality. Five patients experienced complications including 1 delayed gastric empting, 2 bile duct strictures, 1 pancreatic fistula and 1 duodenal stricture. No recurrence or metastasis was found during follow-up. Conclusions In benign and low-grade malignant lesions of pancreatic head, DPPHR could be alternative to traditional surgery. For applying DPPHR in pancreas tumor, a thorough preoperative examination and utilization of frozen section for sufficient resection margin are required.

Abstract
BACKGROUND Angiodysplasia of the duodenum is a rare disorder, often requiring surgical resection. Technical difficulties have made the use of the minimally invasive approach uncommon. Herein, we present a subtotal pancreas-preserving duodenectomy using robotic assistance. METHODS The patient is a 60-y-old female with a long medical history including chronic gastrointestinal bleeding due to angiodysplasia with intermittent melena, and requiring multiples blood transfusions. A capsule endoscopy and double-balloon upper endoscopy showed angiectasis, which appeared to be limited to the third and fourth portion of the duodenum and the proximal loops of the jejunum. Despite multiple endoscopic cauterizations, the patient continued to require blood transfusion for several years. The patient underwent a robot-assisted subtotal pancreas-preserving duodenectomy. RESULTS The operation lasted 420 min with minimal blood loss. The postoperative course was uneventful. The pathology report showed multiple small bowel mucosal and submucosal distorted and dilated vasculature, consistent with angiodysplasia. At 2-mo follow-up, the patient was totally asymptomatic. A barium swallow study showed contrast passed antegrade through the duodenojejunostomy with no evidence of obstruction, stricture, or leakage. CONCLUSION The use of robotic assistance to perform a subtotal pancreas-preserving duodenectomy for the treatment of benign duodenal disease, such as angiodysplasia, is feasible and safe. The technical advantages include a high degree of freedom offered by the robotic instruments, as well as enhanced visualization, which allows for precise microdissection and microsuture, thereby preserving the benefits of minimally invasive surgery. The use of robotic technology allows for a wider range of indications for minimally invasive surgery.

Modified duodenum-preserving pancreas head resection for low-grade malignant lesion in the pancreatic head. Pancreatology 2012; 13:170-4. [PMID: 23561975 DOI: 10.1016/j.pan.2012.12.001] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2012] [Revised: 10/24/2012] [Accepted: 12/02/2012] [Indexed: 12/11/2022]
Abstract
BACKGROUND/OBJECTIVES Our institution has utilized a duodenum-preserving pancreas head resection (DPPHR) procedure for management of low-grade malignant lesions within the head of the pancreas, but this has resulted in a higher rate of postoperative complications, including pancreatic fistula and ischemic bile duct injury. To avoid these complications we recently modified DPPHR to resect all the parenchyma around the pancreatic head and to preserve the epicholedochal plexus around the bile duct. The goal of this study was to investigate outcomes with postoperative complications and disease control following this modified procedure. METHODS Twenty-one consecutive patients underwent DPPHR between 1994 and 2011. Patients were retrospectively classified into one of two groups: the conventional DPPHR group (cDPPHR) or the modified DPPHR group (mDPPHR). Perioperative factors and postoperative complications were compared between these two groups. RESULTS The median age of the 21 patients was 61 (23-77) years, and the median follow-up period was 51 months. Intra-operational blood loss was significantly smaller and duration of hospital stay was significantly shorter in the mDPPHR group than in the cDPPHR group, respectively. The rate of pancreatic fistula was markedly lower in the mDPPHR group (2/13; 15%) than in the cDPPHR group (7/8; 88%) (P = 0.0022). For neoplastic lesions, the surgical margin was negative in all cases, and local recurrence has not occurred in either group. CONCLUSIONS For selected patients, modified DPPHR may provide clinical benefits in terms of less complications associated with shorter hospital stay.

Abstract
BACKGROUND Cystic neoplasms of the pancreas are diagnosed frequently due to early use of abdominal imaging techniques. Intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and serous pseudopapillary neoplasia are considered pre-cancerous lesions because of frequent transformation to cancer. Complete surgical resection of the benign lesion is a pancreatic cancer preventive treatment. OBJECTIVES The application for a limited surgical resection for the benign lesions is increasingly used to reduce the surgical trauma with a short- and long-term benefit compared to major surgical procedures. Duodenum-preserving total pancreatic head resection introduced for inflammatory tumors in the pancreatic head transfers to the patient with a benign cystic lesion located in the pancreatic head, the advantages of a minimalized surgical treatment. PATIENTS Based on the experience of 17 patients treated for cystic neoplastic lesions with duodenum-preserving total pancreatic head resection, the surgical technique of total pancreatic head resection for adenoma, borderline tumors, and carcinoma in situ of cystic neoplasm is presented. A segmental resection of the peripapillary duodenum is recommended in case of suspected tissue ischemia of the peripapillary duodenum. In 305 patients, collected from the literature by PubMed search, in about 40% of the patients a segmental resection of the duodenum and 60% a duodenum and common bile duct-preserving total pancreatic head resection has been performed. RESULTS Hospital mortality of the 17 patients was 0%. In 305 patients collected, the hospital mortality was 0.65%, 13.2% experienced a delay of gastric emptying and a pancreatic fistula in 18.2%. Recurrence of the disease was 1.5%. Thirty-two of 175 patients had carcinoma in situ. CONCLUSION Duodenum-preserving total pancreatic head resection for benign cystic neoplastic lesions is a safe surgical procedure with low post-operative morbidity and mortality.

Abstract
PURPOSE: To evaluate the nutritional status of patients in the late postoperative period of pancreaticoduodenectomy (PD) and compare the long-term outcome according to pylorus-preserving (PPPD) or the standard technique (SPD) in which the pylorus is resected. METHODS: This prospective study was conducted twelve months prior or more in patients who had underwent PD (PD Group, n=15) and health volunteers (Control Group, n=15). At a post hoc analysis, the PD Group was divided in PPPD Subgroup (n=9) and SPD Subgroup (n=6), according to the PD techniques. Gastrointestinal complaints and nutritional status were evaluated, apart from a biochemical assessment; Student t-test or Mann-Whitney test were used. RESULTS: The patients recovered their body weight and the gastrointestinal complaints were uncommon. The PD Group showed higher energy and protein intake even though BMI was lower than in Control Group. There were no differences in laboratorial data, except for higher glycemia, serum alkaline phosfatase and C-reactive protein in PD Group. There was no difference in the various parameters evaluated when the Subgroups (PPPD and SPD) were compared. CONCLUSION: For long-term pancreaticoduodenectomy, the gastrointestinal symptoms are minimal and the patients had the clinical and nutritional status preserved, regardless of pylorus preservation.

Comparison of International Consensus Guidelines versus 18-FDG PET in detecting malignancy of intraductal papillary mucinous neoplasms of the pancreas. Ann Surg 2012; 254:971-6. [PMID: 22076067 DOI: 10.1097/sla.0b013e3182383137] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To assess the reliability of the International Consensus Guidelines (ICG) and 18-fluorodeoxyglucose positron emission tomography (PET) in distinguishing benign from malignant intraductal papillary mucinous neoplasms (IPMNs) of the pancreas. BACKGROUND Since 2006 the ICG have been used to choose immediate surgery or surveillance for IPMN patients, but their low specificity increases the number of benign IPMNs that undergo resective surgery. PET has proved highly sensitive and specific in detecting malignancy in cystic neoplasms of the pancreas, including IPMNs. METHODS Patients suspected with IPMNs of the pancreas seen at our Department from January 1989 to July 2010 were identified and classified as cases of main duct, mixed type and branch type IPMN. The indication for resection or surveillance was verified a posteriori for all patients according to the ICG. PET was considered positive for a Standardized Uptake Value ≥2.5. Surveillance included clinical examination, laboratory tests, CA 19-9 serum levels, and computed tomography and/or magnetic resonance and magnetic resonance cholangiopancreatography every 6 months for 2 years and yearly thereafter. Endoscopic ultrasound was rarely performed. PET was repeated in clinically or radiologically suspect cases, or if tumor markers increased. RESULTS Sixty-one main duct or mixed type and 101-branch type IPMNs were included in the study. A histological diagnosis was available for 81 of 162 patients, missing for 1 locally advanced IPMN, whereas 62 patients are under surveillance and it proved impossible to contact 18. Conservative surgery was performed in 16 of 68 patients with benign IPMNs. The sensitivity, specificity, positive and negative predictive value, and accuracy of the ICG in detecting malignancy were 93.2, 22.2, 59.4, 72.7, and 61.2, whereas for PET they were 83.3, 100, 100, 84.6, and 91.3. CONCLUSIONS PET is more accurate than the ICG in distinguishing benign from malignant (invasive and noninvasive) IPMNs. Prophylactic IPMN resection in young patients fit for surgery should be guided by the ICG, whereas PET should be performed in older patients, cases at increased surgical risk, or when the feasibility of parenchyma-sparing surgery demands a reliable preoperative exclusion of malignancy.
