Prospective cohort study on short-term outcomes of 3D-laparoscopic pancreaticoduodenectomy with stented pancreaticogastrostomy. Surg Endosc 2023; 37:1203-1212. [PMID: 36163561 DOI: 10.1007/s00464-022-09609-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 09/03/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND Minimally invasive pancreaticoduodenectomy, either laparoscopic or robotic, is a high-risk procedure with demanding learning curve. The aim of this prospective cohort study was to evaluate short-term clinical and oncologic outcomes of 3D-laparoscopic pancreaticoduodenectomy (3dLPD) with stented pancreaticogastrostomy (sPG) and Roux-en-Y gastroenterostomy (ryGES). METHODS Between March 2016 and July 2021, 347 consecutive patients underwent 3dLPD for confirmed or suspected pancreatic or periampullary tumors. Pancreatic duct diameter measured 3 mm or less in 221 (64%) and pancreatic texture was soft in 191 (55%) patients. Simultaneous resection of the superior mesenteric or portal vein was performed in 52 (15%) patients. RESULTS Postoperative complications were observed in 189 (54%) patients, with severe complications (Clavien-Dindo grade > 2) in 68 (20%) including 4 (1.2%) deaths. Clinically relevant pancreatic fistula (cPOPF) occurred in 88 (25%), hemorrhage in 25 (7%), and bile leakage in 10 (3%) patients. Clinical pancreatic fistula was strongly associated with soft pancreatic texture and small pancreatic duct diameter (p < 0.001) and managed by endoscopic trans-gastric drainage in 34 (38.6%) patients, reoperation in 12 (13.6%), and ICU admission in 11 (12.5%). The remaining 31 (35%) patients with cPOPF were managed without invasive intervention. Median length of hospital stay after surgery was 13 (range 5-112; IQR 8-18) days. In pancreatic adenocarcinoma (PDAC) the R0-resection rate was 66/186 (36%), R1-indirect 95/186 (51%), and R1-direct 25 (13%). Median number of locoregional lymph nodes retrieved in PDAC was 21 (IQR 15-28). R0-resection rate for malignancy other than PDAC was 78/86 (91%) with a median of 16 (IQR 12-22) locoregional lymph nodes retrieved. CONCLUSION 3dLPD with sPG and ryGES is associated with 1.2% mortality and 25% cPOPF. About two-third of patients with cPOPF were managed with some type of invasive intervention, whereas the intraoperatively placed drains sufficed in one-third of patients.

To compare the outcomes of pancreaticojejunostomy and pancreaticogastrostomy reconstruction after pancreaticoduodenectomy: A prospective observational study. Med J Armed Forces India 2023; 79:64-71. [PMID: 36605340 PMCID: PMC9807657 DOI: 10.1016/j.mjafi.2021.08.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Accepted: 08/17/2021] [Indexed: 02/07/2023] Open
Abstract
Background We have been in constant search of novel innovations to decrease the high morbidity after Pancreaticoduodenectomy (PD). Pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) are the two different methods of reconstruction after PD. However, the existing data is ambiguous in supporting either of them as the preferred technique of reconstruction. Methods This was a single-center prospective observational study that included 64 patients who underwent PD over two years. We compared PG with PJ as a method of reconstruction after PD. The primary objective was to assess whether PG decreases the rate of postoperative pancreatic fistula (POPF) rates or not. Secondary objectives comprised analysis of perioperative outcomes, 30-day and 90-day mortality. Results Pancreatic fistula was significantly lower in PG as compared to the PJ group (24% vs. 47%) with a p-value of 0.027. The incidence of clinically pertinent (grade B) fistula was only 3% in the PG group and 32% in the PJ group. PG group had a higher incidence of post pancreatectomy hemorrhage (PPH) and delayed gastric emptying (DGE). No statistically significant difference was seen between either group need for blood transfusion, re-exploration, re-admissions, ICU stay, or length of hospital stay, and 30-day and 90-day mortality. Pancreatic texture and high BMI were independent predictors for pancreatic fistula. Conclusion PG when compared to PJ for reconstruction after PD, decreases the rate of POPF significantly; however, it is associated with an elevated risk of DGE and PPH. There was no difference in 30-day and 90-day mortality between both the treatment groups.

Conversion to pancreaticogastrostomy for salvage of disrupted pancreaticojejunostomy following pancreaticoduodenectomy. Ann Surg Treat Res 2022; 103:217-226. [PMID: 36304194 PMCID: PMC9582620 DOI: 10.4174/astr.2022.103.4.217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 08/09/2022] [Accepted: 08/30/2022] [Indexed: 11/30/2022] Open
Abstract
Purpose This study aimed to report on a pancreas-preserving strategy consisting of the conversion to pancreaticogastrostomy (PG) for the salvage of disrupted pancreaticojejunostomy (PJ) following pancreaticoduodenectomy (PD). Methods This single-center retrospective study included 188 patients who underwent PD between March 2000 and June 2021. Conversion to PG was performed by placing the pancreatic stump with an internal stent in the stomach through the posterior gastrostomy and suturing the wound in 2 layers through the anterior gastrostomy. Results A total of 181 patients underwent PJ, while 7 underwent PG. Of all patients, 6 had International Study Group on Pancreatic Fistula grade C postoperative pancreatic fistulae (POPF; 3.3%) and 23 had grade B POPF (12.7%). Two of the 6 grade C patients underwent completion pancreatectomy and died of liver failure after common hepatic artery embolization due to pseudoaneurysm. Conversion to PG was performed in 4, all of whom survived and experienced no long-term pancreatic fistulae, remnant pancreatic atrophy, or newly developed diabetes after a median follow-up period of 11.5 months. Conclusion Conversion to PG for the salvage of disrupted PJ following PD is safe and effective in selected patients that can lower mortality rates while maintaining pancreatic function.

Abstract
We comment on a study titled “Feasibility and safety of "bridging" pancreaticogastrostomy for pancreatic trauma in Landrace pigs” in which ten pigs were randomized to either experimental “bridging” pancreaticogastrostomy (PG) or a control group with a routine mucosa-to-mucosa PG. At six months anastomoses had strictured and closed in both groups. The authors concluded that “bridging” PG is feasible and safe in damage control surgery during the early stage of pancreatic injury. In this letter we comment on the study design, specifically leaving a 2 cm gap between the pancreatic stump and the stomach and highlight the complexity of performing pancreatic anastomoses following trauma pancreaticoduodenectomy as to our experience in a high volume trauma centre. Our data emphasize that pancreatic anastomoses in trauma are complex procedures with significant postoperative morbidity and are best managed collaboratively by trauma and hepatopancreaticobiliary surgical teams with the required technical skills.

Clinicopathological features of gastric cancer after pancreaticoduodenectomy: reporting of three institutional cases and review of the global literature. Langenbecks Arch Surg 2022; 407:2259-2271. [PMID: 35522321 DOI: 10.1007/s00423-022-02524-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Accepted: 04/19/2022] [Indexed: 11/26/2022]
Abstract
PURPOSE Gastric cancer after pancreaticoduodenectomy was firstly reported in 1995, and the number of reports about this topic has increased in the past years. This review aimed to elucidate the clinicopathological features of this disease. METHODS Data for 32 cases were obtained using literature search, and three cases in our institution were added. RESULTS Twenty cases were reported from Japan, and fifteen cases were from the Western countries (Germany: 1 case, France: 2 cases, USA: 12 cases). In Japanese and the Western cases, the most dominant indication for pancreaticoduodenectomy was distal bile duct cancer and pancreatic ductal adenocarcinoma, respectively. The most frequently applied procedure of pancreaticoduodenectomy was pylorus-preserving pancreatoduodenectomy with pancreaticogastrostomy and pancreaticoduodenectomy with pancreaticojejunostomy, respectively. The median length of time interval from pancreaticoduodenectomy to GC detection tended to be shorter in the Japanese cases (61.5 months vs. 115 months). Of all cases, thirteen (37.1%) patients with gastric cancer showed no abdominal symptoms, and eight were diagnosed at regular gastroscopy. Surgical gastrectomy was performed in 30 patients, and among them, concomitant pancreatectomy was performed in six patients. Four patients received reanastomosis of remnant pancreas using pancreaticojejunostomy. Twenty-two (73.3%) patients had undifferentiated carcinomas, and stage 1, 2, 3, and 4 cancer was identified in 14, six, six, and four patients, respectively. All eight patients who had received routine gastroscopy were T1N0M0 stage 1. CONCLUSION Gastric cancers after pancreaticoduodenectomy including newly reported Japanese cases and our institutional cases were reviewed to make Japanese studies available to a broader scientific audience. Further investigation is necessary to elucidate the most important carcinogens among the various potential local and systemic factors.

Abstract
PURPOSE The optimal pancreaticogastrostomy (PG) method for reducing pancreatic fistula (PF) incidence remains unclear. This retrospective review aimed to evaluate the clinical impact of the "twin U-stitch method" and compared it with the conventional invagination method. METHODS Data of 183 consecutive patients who underwent PG after pancreaticoduodenectomy (PD) between January 2015 and November 2020 were evaluated. PF incidence was compared between patients who experienced twin U-stitch PG (twin U-stitch group) and those who experienced conventional invagination PG (conventional PG group). RESULTS The twin U-stitch and conventional PG methods were performed in 97 and 86 patients, respectively. The time required for twin U-stitch PG was shorter than conventional PG (9.3 min vs 20.0 min, P < 0.001). The twin U-stitch group showed a lower incidence of PF than the conventional PG group (8% vs. 19%, P = 0.038). Multivariate analysis confirmed that twin U-stitch PG was significantly correlated with a decreased risk of PF (odds ratio, 0.23; P = 0.006), independent of the texture of the pancreas. Subgroup analysis of patients with soft-textured pancreas showed that the median drain amylase levels in the twin U-stitch group on postoperative days (POD) 1 and 3 were significantly lower than those in the conventional PG group (POD 1: 1,335 vs. 5,991 U/L, P < 0.001; POD 3: 212 vs. 518, P = 0.001). CONCLUSION The twin U-stitch method was simple and preferable to the conventional method for preventing PF in patients with PD.

Double purse-string telescoped pancreaticogastrostomy is not superior in preventing pancreatic fistula development in high-risk anastomosis: a 6-year single-center case-control study. Langenbecks Arch Surg 2021; 407:1073-1081. [PMID: 34782930 DOI: 10.1007/s00423-021-02376-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2021] [Accepted: 11/03/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE The double purse-string telescoped pancreaticogastrostomy (PG) technique has been suggested as an alternative approach to reduce the risk of postoperative pancreatic fistula (POPF). Its efficacity in high-risk situations has not yet been explored. This study compared the incidence of clinically relevant POPF (CR-POPF) between patients with high-risk anastomosis undergoing PG and those undergoing pancreaticojejunostomy (PJ). METHODS From 2013 to 2019, 198 consecutive patients with high-risk anastomosis, an updated alternative fistula risk score > 20%, and who underwent pancreatoduodenectomy with the PJ (165) or PG (33) technique were included. Optimal mitigation strategy (external stenting/octreotide omission) was applied for all patients. The primary endpoint was the incidence of CR-POPF. RESULTS The mean ua-FRS was 33%. CR-POPF (grade B/C) was found in 42 patients (21%) and postoperative hemorrhage in 30 (15%); the mortality rate was 4%. CR-POPF rates were comparable between the PJ (19%) and PG (33%) groups (P = 0.062). The PG group had a higher rate of POPF grade C (24% vs. 10%; P = 0.036), longer operative time (P = 0.019), and a higher transfusion rate (P < 0.001), even after a matching process on ua-FRS. In the multivariate analysis, the type of anastomosis (P = 0.88), body mass index (P = 0.47), or main pancreatic duct diameter (P = 0.7) did not influence CR-POPF occurrence. CONCLUSIONS For patients with high-risk anastomosis, the double purse-string telescoped PG technique was not superior to the PJ technique for preventing CR-POPF.

Abstract
Background Pylorus-preserving pancreatoduodenectomy (PPPD) with pancreatogastrostomy is a standard surgical procedure for pancreatic head tumors, duodenal tumors and distal cholangiocarcinomas. Post-operative pancreatic fistulas (POPF) are a major complication causing relevant morbidity and mortality. Endoscopic vacuum therapy (EVT) has become a widely used method for the treatment of intestinal perforations and leakages. Here we report on a pilot single center series of 8 POPF cases specifically caused by dehiscences of the pancreatogastric anastomosis (PGD), successfully managed by EVT. Methods We included all patients with PGD after PPPD, who were treated with EVT between 07/2017 and 08/2020. For EVT a vacuum drainage film (EVT film) or open-pore polyurethane foam sponge (EVT sponge) was fixed to a 14Fr or 16Fr suction catheter and placed endoscopically within the PGD for intracavitary EVT with continuous suction between − 100 and − 150 mmHg. The EVT film/sponge was exchanged twice per week. EVT was discontinued when the PGD was sufficiently healed. Results PGD closure was achieved in 7 of 8 patients after a mean EVT time of 16 days (range 8–38) and 3 EVT film/sponge exchanges (range 1–9). One patient died on day 18 after PPPD from acute hemorrhagic shock, unlikely related to EVT, before effectiveness of EVT could be fully achieved. There were no adverse events directly attributable to EVT. Conclusions EVT could be an effective and safe addition to our therapeutic armamentarium in the management of POPF with PGD. Unless prospective comparative studies are available, EVT as minimally invasive therapeutic alternative should be considered individually by an interdisciplinary team involving endoscopists, surgeons and radiologists.

Abstract
Background To evaluate the outcomes of pancreaticogastrostomy and pancreaticojejunostomy after pancreatoduodenectomy with the help of a meta-analysis. Methods Randomized controlled trials comparing pancreaticogastrostomy and pancreaticojejunostomy were searched electronically using PubMed, The Cochrane Library, and EMBASE. Fixed and random-effects were used to measure pooled estimates. Research indicators included pancreatic fistula, delayed gastric emptying, postoperative hemorrhage, intraperitoneal fluid collection, wound infection, overall postoperative complications, reoperation, and mortality. Results Overall, 10 randomized controlled trials were included in this meta-analysis, with a total of 1629 patients. The overall incidences of pancreatic fistula and intra-abdominal collections were lower in the pancreaticogastrostomy group than in the pancreaticojejunostomy group (OR=0.73, 95% CI 0.55~0.96, p=0.02; OR=0.59, 95% CI 0.37~0.96, p=0.02, respectively). The incidence of B/C grade pancreatic fistula in the pancreaticogastrostomy group was lower than that in the pancreaticojejunostomy group, but no significant difference was observed (OR=0.61, 95%CI 0.34~1.09, p=0.09). Postoperative hemorrhage was more frequent in the pancreaticogastrostomy group than in the pancreaticojejunostomy group (OR=1.52; 95% CI 1.08~2.14, p=0.02). No significant differences in terms of delayed gastric emptying, wound infection, reoperation, overall postoperative complications, mortality, exocrine function, and hospital readmission were observed between groups. Conclusion This meta-analysis suggests that pancreaticogastrostomy reduces the incidence of postoperative pancreatic fistula and intraperitoneal fluid collection but increases the risk of postoperative hemorrhage compared with pancreaticojejunostomy.

Abstract
Traumatic injury to the main pancreatic duct requires surgical treatment, but optimal management strategies have not been established. In patients with isolated pancreatic injury, the pancreatic parenchyma must be preserved to maintain long-term quality of life. We herein report a case of traumatic pancreatic injury with main pancreatic duct injury in the head of the pancreas. Two years later, the patient underwent a side-to-side anastomosis between the distal pancreatic duct and the jejunum. Eleven years later, he presented with abdominal pain and severe gastrointestinal bleeding from the Roux limb. Emergency surgery was performed with resection of the Roux limb along with central pancreatectomy. We attempted to preserve both portions of the remaining pancreas, including the injured pancreas head. We considered the pancreatic fluid outflow tract from the distal pancreatic head and performed primary reconstruction with a double pancreaticogastrostomy to avoid recurrent gastrointestinal bleeding. The double pancreaticogastrostomy allowed preservation of the injured pancreatic head considering the distal pancreatic fluid outflow from the pancreatic head and required no anastomoses to the small intestine.

Abstract
INTRODUCTION Postoperative pancreatic fistula (POPF) represents the principal determinant of morbidity and mortality after pancreaticoduodenectomy. Since 1994 we have been performing pancreaticogastrostomy with duct-to-mucosa anastomosis (Wirsung-pancreaticogastric anastomosis [WPGA]), but postoperative morbidity, although limited, was still a concern. An original pancreas-transfixing suture technique, named "Blumgart's anastomosis" (BA), has shown efficacy at reducing fistula rates from pancreaticojejunostomy. Few cohort studies have shown that WPGA with pancreas-transfixing stitches may help reduce the rate of POPF. We designed a novel "Blumgart-type" modification of WPGA (B-WPGA) aiming at harnessing the full potential of the Blumgart design. METHODS A prospective development study was designed around the application of B-WPGA after pancreaticoduodenectomy for primary periampullary tumors. It focused on describing the early iterations of this technique and on assessing the rate of POPF and delayed post-pancreatectomy hemorrhage (DPH) (primary outcomes), along with other perioperative outcomes. Technically, after mobilizing the pancreatic remnant for a few centimeters, the Wirsung duct is cannulated. A lozenge of seromuscular layer is excised from the posterior gastric wall, matching the shape and size of the pancreas's cut surface. Two to four transparenchymal pancreatic-to-gastric submucosa U stitches with 4/0 Gore-Tex are positioned cranially and caudally to the Wirsung duct, respectively, mounted on soft clamps, and tied onto the gastric serosa only after duct-to-mucosa anastomosis. Postoperative follow-up was standardized by protocol and included a pancreatic enzyme check on the drain output. RESULTS From February 2018 to June 2019, in 15 continuous cases, B-WPGA was performed after pancreaticoduodenectomy. Indications for pancreaticoduodenectomy were mainly ampulla of Vater and pancreatic head adenocarcinomas. There was no operative mortality and no pancreatic anastomosis-related morbidity. Two events (13%) of transiently elevated amylase in the drain fluid, not matching the definition of POPF, were identified in patients with a soft pancreas on postoperative day 2. No DPHs were recorded after a minimum follow-up of 18.6 months. DISCUSSION/CONCLUSION The principles of BA may be safely applied to the WPGA model. B-WPGA allows (1) gentle compression and closure of the small secondary ducts in the pancreatic remnant; (2) partial invagination of the pancreatic body in the gastric wall, with the pancreatic cut surface protected by the gastric submucosa; and (3) prevention of parenchymal fractures, as the pancreaticogastric stitches are tied onto the gastric serosa. Despite the limited number of cases in this study, the absence of mortality and anastomosis-related complications supports further reproduction of this technical variant. Larger studies are necessary to determine its efficacy.

Abstract
BACKGROUND Pancreaticoduodenectomy (PD) plays an integral part in the management of pancreatic, periampullary and duodenal cancers, along with a few other pathologies of this region. Despite advances in surgery PD continues to have significant morbidity and noteworthy mortality. The aim of this study is to provide an in-depth report on the patient characteristics, indications and the outcomes of PD) in a tertiary cancer hospital in Pakistan. MATERIALS AND METHODS The study population included patients who underwent PD between January 1, 2014 and march 31, 2019, at Shaukat Khanum Memorial Cancer Hospital and Research Center (SKMCH&RC) in Pakistan. The data was retrospectively analyzed from the Hospital Information System (HIS), which is a prospectively maintained patient electronic database of SKMCH&RC. Patient characteristics, procedural details and post-operative outcomes according to internationally accepted definitions were reported. RESULTS A total of 161 patients underwent PD at our hospital in the study period at a median age of 53 years, ranging from 19 to 78 years. 62% of the patients were males while 37% were females. Jaundice was the most common presenting symptom (64.6%), followed by abdominal pain (26.7%). PD with pancreaticogastrostomy was performed in 110 patients (68.3%), while pancreaticojejunostomy was performed in the rest of the cohort. Surgical site infection (SSI) was observed in 64 patients (40%). The incidence of Pancreatic Fistula grade C based on the International Study Group on Pancreatic Fistula (ISGPF) definition was 7.45% (n = 12). The 30 days mortality rate was 3.1%. Median survival of the cohort was 21 ±1.13 months and disease-free survival was 16±2.62 months. CONCLUSION PD can be performed with acceptable morbidity and mortality in a resource constrained country, as long as it is undertaken in a high-volume center. This is in keeping with data published from other well-reputed international centers.

Abstract
PURPOSE To investigate the differences in nutritional status 1 year after pancreaticogastrostomy (PG) using vertical suturing (VS) vs. twin square horizontal mattress (HMS) suturing in patients undergoing pancreaticoduodenectomy (PD). METHODS The subjects of this study were 134 patients who underwent PD, followed by PG, which was closed by VS in 52 and by HMS in 82. We evaluated the peri- and postoperative factors, nutritional parameters, diameter of the remnant main pancreatic duct, and glucose intolerance 1 year postoperatively. RESULTS Forty-five (87%) patients from the VS group and 75 (91%) patients from the HMS group survived for more than 1 year. The incidences of intraabdominal abscess and pancreatic fistula were significantly lower in the HMS group than in the VS group (19.2% vs. 6.6% and19.2% vs. 2.6%, respectively). There were no significant changes in the total protein, serum albumin, and HbA1c levels 1 year postoperatively. The postoperative expansion ratio of the main pancreatic duct diameter was significantly smaller in the HMS group than in the VS group. The strongest risk factor for body weight loss 1 year postoperatively was a non-soft pancreas texture. CONCLUSION HMS was superior to VS for preventing early postoperative complications and did not affect pancreatic function.

Abstract
PURPOSE Delayed gastric emptying (DGE) is an important postoperative complication after pancreaticoduodenectomy (PD), and its incidence may be associated with the utilized surgical procedures. Compared with pancreaticojejunostomy (PJ) after PD, it may be speculated that pancreaticogastrostomy (PG) is a risk factor for DGE, because it needs an anastomosis of the remnant pancreas to the back wall of the stomach. This study aimed to compare PG and PJ with regard to the incidence of DGE after PD. METHODS We performed a prospective open-label randomized clinical trial (RCT) including patients undergoing elective pancreaticoduodenectomy, who were randomly assigned PG or PJ the day before surgery. The primary endpoint was incidence of DGE. RESULTS The study included 60 patients (30 PG, 30 PJ), of whom seven were deemed unresectable, one was enucleated, and one was switched from PJ to PG during surgery according to the surgeon's decision. Thus, modified intention-to-treat analyses were performed in 27 PG patients and 26 PJ patients. DGE occurred in three patients in the PG group and six patients in the PJ group, which did not constitute a significant between-group difference (P = 0.42). In the PG group, two cases were ISGPS grade A DGE and one was grade C. In the PJ group, one case was grade A, two grade B, and three grade C. The two groups also did not significantly differ in the incidence of other morbidities or postoperative hospital stay. CONCLUSIONS Post-PD DGE incidences were similar after PG and PJ.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains a major cause of morbidity following pancreaticoduodenectomy (PD). This network meta-analysis (NMA) compared techniques of pancreatic anastomosis following PD to determine the technique with the best outcome profile. METHODS A systematic literature search was performed on the Scopus, EMBASE, Medline and Cochrane databases to identify RCTs employing the international study group of pancreatic fistula (ISGPF) definition of POPF. The primary outcome was clinically relevant POPF. RESULTS Five techniques of pancreatic anastomosis following PD were directly compared in 15 RCTs comprising 2428 patients. Panreatojejunostomy (PJ) end-to-side invagination vs. PJ end-to-side duct-to-mucosa was the most frequent comparison (n = 7). Overall, 971 patients underwent PJ end-to-side duct-to-mucosa, 791 patients PJ end-to-side invagination, 505 patients pancreatogastrostomy (PG) end-to-side invagination, 98 patients PG end-to-side duct-to-mucosa, and 63 patients PJ end-to-side single layer. PG duct-to-mucosa was associated with the lowest rates of clinically relevant POPF, delayed gastric emptying, intra-abdominal abscess, all postoperative morbidity and postoperative mortality, the shortest operative time and postoperative hospital stay and the lowest volume of intra-operative blood loss. CONCLUSION Duct-to-mucosa pancreaticogastrostomy was associated with the lowest rates of clinically relevant POPF and had the best outcome profile among all techniques of pancreatico-anastomosis following PD.

Abstract
The aim of the present paper was to describe a new and easy technique for performing pancreaticogastrostomy (PG) through simple pancreatic invagination by a single binding suture without suturing the pancreatic parenchyma. The present study included all consecutive patients who underwent elective pancreaticoduodenectomy from 2007 to 2015. The intraoperative and postoperative outcomes after PG (PG group) were compared with those of patients who underwent pancreaticojejunostomy (PJ) (PJ group). Out of 270 patients, 88 PG and 182 PJ patients were assessed. The rate of clinically significant PF was similar between the PG and PJ groups (10.2% vs. 13.2%, respectively; p = 0.487), despite the risk of pancreatic fistula being higher in the PG group. There were no significant differences in the intraoperative and postoperative outcomes or mortality between the groups. This easy invagination technique for PG is simple, safe and reproducible with a low risk of postoperative pancreatic fistula.

Abstract
BACKGROUND Pancreatoduodenectomy (PD) is one of the most important operations in hepatobiliary and pancreatic surgery.
AIM To evaluate the advantages and disadvantages of pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG).
METHODS This meta-analysis was performed using Review Manager 5.3. All clinical randomized controlled trials, in which patients underwent PD with pancreatico-digestive tract reconstruction via PJ or PG, were included.
RESULTS The search of PubMed, Wanfang Data, EMBASE, and the Cochrane Library provided 125 citations. After further analysis, 11 trials were included from nine counties. In all, 909 patients underwent PG and 856 underwent PJ. Meta-analysis showed that pancreatic fistula (PF) was a significantly lower morbidity in the PG group than in the PJ group (odds ratio [OR] = 0.67, 95% confidence interval [CI]: 0.53-0.86, P = 0.002); however, grades B and C PF was not significantly different between the two groups (OR = 0.61, 95%CI: 0.34-1.09, P = 0.09). Postoperative hemorrhage showed a significantly lower morbidity in the PJ group than in the PG group (OR = 1.47, 95%CI: 1.05-2.06, P = 0.03). Delayed gastric emptying was not significantly different between the two groups (OR = 1.09, 95%CI: 0.83-1.41, P = 0.54).
CONCLUSION There is no difference in the incidence of grades B and C PF between the two groups. However, postoperative bleeding is significantly higher in PG than in PJ. Binding PJ or binding PG is a safe and secure technique according to our decades of experience.

Abstract
The advancement of pancreatic endotherapy has increased the availability of minimally invasive endoscopic pancreatic ductal drainage techniques. In this regard, familiarity with endoscopic ultrasound-guided pancreatic duct drainage (EUS-PDD) is critical for treatment of obstructed pancreatic ductal systems, especially in nonsurgical candidates and in patients desiring a minimally invasive approach. Two distinct forms of EUS-PDD exist, viz. rendezvous-assisted endoscopic retrograde pancreatography (rendezvous-assisted ERP) and anterograde EUS-PDD. Anterograde EUS-PDD refers to transmural anterograde passage of a pancreatic drainage catheter or stent directly into the main pancreatic duct, through either the gastric or enteral wall. Rendezvous-assisted ERP should be attempted after failed conventional ERP, and anterograde EUS-PDD should be considered if rendezvous-assisted ERP fails or is not technically feasible. Common clinical scenarios that fulfil these conditions are chronic pancreatitis with high-grade main pancreatic duct obstruction, surgically altered anatomy with ductal/anastomotic obstruction, pancreas divisum, and disconnected pancreatic duct syndrome. The focus of this review article is anterograde EUS-PDD and its indications, technique, and outcomes. It also provides a summary of our own experience with this procedure, and a video demonstration of the technique.

Abstract
BACKGROUND Pancreatico-enteric anastomosis after pancreaticoduodenectomy can be performed using either a pancreaticojejunostomy (PJ) or pancreaticogastrostomy (PG). Differences in surgical outcomes are still a matter of debate, and less is known about long-term functional outcomes. METHODS Twelve years after the conclusion of a comparative study evaluating the surgical outcomes of PJ and PG (Bassi et al., Ann Surg 2005), available patients underwent morphological and functional pancreatic assessment: pancreatic volume and duct diameter measured by MRI, impaired secretion after secretin, fecal fat, fecal elastase-1 (FE-1), serum vitamin D and endocrine function. Quality of life and symptom scores were evaluated with the EORTC QLQ-C30 questionnaire. RESULTS Only 34 patients were available for assessment. No differences were found in terms of BMI variation, endocrine function, quality of life or symptoms. Exocrine function was more severely impaired after PG than after PJ (fecal fats 26.6 ± 4.1 vs 18.2 ± 3.6 g/day; FE-1 121.4 ± 6.7 vs 170.2 ± 25.5 μg/g, vitamin D 18.1 ± 1.8 vs. 23.2 ± 3.1 ng/mL). MRI assessment identified a lower pancreatic volume (26 ± 3.1 vs. 36 ± 4.1 cm3) and a more dilated pancreatic duct (4.6 ± 0.92 vs. 2.4 ± 0.18 mm) in patients with PG compared to those with PJ. CONCLUSION Compared to PJ, PG is associated with a more severely impaired exocrine function long-term, but they result similar endocrine function and quality of life. In patients with a long life expectancy, this should be taken into account.

Abstract
BACKGROUND Patients who undergo pancreaticoduodenectomy (PD) have the pancreatic remnant (PR) anastomosed to the jejunum. In this study, all patients had the PR anastomosed to the stomach. Our aims are to evaluate postoperative outcomes of patients undergoing PD with pancreaticogastrostomy (PG). METHODS There was 453 patients who underwent PD with PG. Preoperative characteristics, intraoperative data, and postoperative outcomes were analyzed using univariate and multivariate models. RESULTS The patient cohort had a median age of 67 years and underwent resection for pancreatic (40.8%), ampullary (15.9%), duodenal (6.6%), distal bile duct (6.4%) cancers. Multivariate analysis revealed poor prognosis was related to age, tumor diameter, lymph node ratio, perineural invasion, and tumor differentiation in patients with periampullary adenocarcinoma. CONCLUSIONS This series of patients undergoing PD with PG shows that the operation can be performed safely with excellent outcomes for a variety of malignant and benign conditions.

Abstract
Pancreatic fistula is one of the most common and serious complications after digestive tract reconstruction.Grade A pancreatic fistula is defined as biochemical fistula only when the drainage fluid amylase level is elevated without affecting clinical decision-making.It is not a true pancreatic fistula, or a real surgical complication.Surgeons should pay more attention to the diagnosis and treatment of B and C pancreatic fistula, and it is more valuable to reduce the occurrence of B and C pancreatic fistula.Pancreatic fistula is not a purely surgical technical problem, but the quality of surgical reconstruction is very important.For pancreatic surgeons, the reconstruction of the pancreatic stump digestive tract after pancreaticoduodenectomy is accompanied by both opportunities and challenges.

Abstract
Stenosis of the pancreatico-enteric anastomosis following pancreatoduodenectomy (PD), a late post-operative complication that is seen mainly after PD for diseases with good prognosis, has been reported in less than 3% of cases in the literature. Most often asymptomatic, pancreatic-enteric anastomotic stenosis can lead to pancreatitis, pain or pancreatic insufficiency. Symptomatic stenosis is difficult to treat and its management is not standardized. Magnetic resonance cholangiopancreatography is the best investigation to confirm the diagnosis of stenosis. The Endoscopic UltraSonography (EUS) « rendezvous » technique, associating an endoscopic approach and EUS-guided puncture of the main pancreatic duct, has been available since 2010. Of note, however, the failure rate of the EUS series is as high as 25%, leading to repeat procedures. Surgical reconstruction of the anastomosis has been reported with good results in terms of morbidity. Surgical re-do of the pancreatico-enteric anastomosis for stenosis following PD carries a low risk of pancreatic fistula (around 5%) and an overall morbidity rate of around 20%.

Abstract
A 62-year-old man underwent endoscopic mucosal resection for early gastric cancer. The follow-up computed tomography revealed biliary dilatation. The tumor was located in the lower bile duct with biliary dilatation, and no evidence of metastasis in other organs was noted. The patient underwent subtotal stomach-preserving pancreatoduodenectomy with pancreaticogastrostomy and Billroth I anastomosis. At 13 months after the operation, gastrointestinal endoscopy revealed a tumor lesion in the pancreaticogastrostomy site. Computed tomography revealed that the lesion was low enhanced in the pancreaticogastrostomy site and there was no evidence of other distant metastasis. Partial pancreatectomy was performed. Pathological findings of the tumor in the stump of the pancreas revealed findings similar to that of primary biliary carcinoma. Apparently, the patient was diagnosed with recurrence of bile duct cancer via the pancreatic duct. The patient underwent adjuvant chemotherapy for one year subsequent to partial pancreatectomy as the second operation. For 40 months after the second operation, there has been no evidence of recurrence of cancer.

Abstract
Pancreatic fistula (PF) remains the Achilles' heel of pancreaticoduodenectomy (PD). Pancreaticogastrostomy (PG) appears to be associated with a lower risk of postoperative leak according to recent evidence. We started to fashion PG, especially in soft pancreas, modifying the original technique described by Bassi. At our institution, 105 PD procedures were carried out from January 2011 to December 2016; pancreatic-enteric continuity was restored by PG in 35 cases. Superior mesenteric/portal vein resection/reconstruction was necessary in three patients. A total of 34/35 patients underwent PG with an open anterior gastrostomy approach. Briefly, our double-layer PG anastomosis (illustrated by a video) starts with a posterior row of interrupted absorbable 4/0 monofilament sutures including the gastric serosa and the pancreatic capsule. It is essential to mobilize the left pancreas for 4-5 cm and to shape the posterior gastrostomy shorter than the pancreatic stump. After a wide anterior auxiliary gastrostomy the pancreas is invaginated into the stomach and an interrupted row of sutures between the posterior gastric wall (full-thickness) and the body of the pancreatic stump is fashioned. The anterior gastrostomy is closed with an absorbable running suture. Finally, a further layer of sutures is applied over the posterior suture line between the gastric serosa and the pancreatic capsule. The 90-day postoperative mortality was nihil. No biliary leakage was detected and the overall PF rate was 11.4% (4/35) according to the ISGPF study group. Only one patient suffered a grade B PF (in this case, PG was carried out only through a posterior gastrostomy), whereas three patients had a minor (grade A) PF. Our modified PG proved to be safe and easy to perform, while it carried excellent outcomes even in the setting of soft pancreas. Despite the limited number of cases, such modified PG appears promising, particularly for pancreatic remnants at higher risk of PF.

Abstract
AIM To evaluate the evolution, trends in surgical approaches and reconstruction techniques, and important lessons learned from performing 1000 consecutive pancreaticoduodenectomies (PDs) for periampullary tumors.
METHODS This is a retrospective review of the data of all patients who underwent PD for periampullary tumor during the period from January 1993 to April 2017. The data were categorized into three periods, including early period (1993-2002), middle period (2003-2012), and late period (2013-2017).
RESULTS The frequency showed PD was increasingly performed after the year 2000. With time, elderly, cirrhotic and obese patients, as well as patients with uncinate process carcinoma and borderline tumor were increasingly selected for PD. The median operative time and postoperative hospital stay decreased significantly over the periods. Hospital mortality declined significantly, from 6.6% to 3.1%. Postoperative complications significantly decreased, from 40% to 27.9%. There was significant decrease in postoperative pancreatic fistula in the second 10 years, from 15% to 12.7%. There was a significant improvement in median survival and overall survival among the periods.
CONCLUSION Surgical results of PD significantly improved, with mortality rate nearly reaching 3%. Pancreatic reconstruction following PD is still debatable. The survival rate was also improved but the rate of recurrence is still high, at 36.9%.

Abstract
OBJECTIVE To evaluate the clinically relevant POPF rate between Pancreatogastrostomy (PG) and pancreaticojejunostomy (PJ) after pancreaticoduodenectomy (PD). To evaluate the confounding factors affecting meta-analytic results. METHODS A systematic literature search of randomized clinical trials (RCTs) comparing PG to PJ with an International Study Group of Pancreatic Fistula (ISGPF) definition of postoperative pancreatic fistula (POPF). Risk difference (RD) and number needed to treat or harm (NNT and NNH) were used. Fixed and random-effect models were applied. Impact of confounding covariates on the meta-analytic results was evaluated using meta-regression analysis, reporting β coefficient ± standard error (SE). RESULTS Seven RCTs were identified involving 1184 patients: 603 PG and 581 PJ. RD in the fixed model of clinically relevant POPFs suggested that PG was superior to PJ (RD-0.07; 95% CI: -0.11 to -0.03) with an NNT of 14 (95% CI: 9 to 33). In random model, PG was not superior to PJ (RD-0.06; 95% CI: -0.13 to 0.01) with an NNT of 17 and a possibility of harm in some cases (NNH = 100). Meta-regression suggested that the increase in the proportion of "soft pancreas" in the PG arm corresponded to a more positive value of RD (β = 0.47 ± 0.19; P value: 0.045 ± 0.003). CONCLUSION A PG could be slightly superior to PJ in the prevention of clinically relevant POPF. The presence of high risk pancreatic remnant remains the main limitation of PG.

Abstract
OBJECTIVE The present study aimed to assess the safety of pancreatic anastomosis after pancreaticoduodenectomy (PD) and to compare the results of sutureless pancreatogastrostomy (PG) with those of single-layer duct-to-mucosa pancreatojejunostomy (PJ) after PD in patients with malignant disease of the pancreatic head and of the periampullary region. MATERIALS AND METHODS The study included 173 consecutive patients undergoing PD from May 2009 to December 2015 at a single surgical center. Single-layer duct-to-mucosa PJ was performed in 52 patients and sutureless PG in the remaining 123. The primary endpoint was the safety of the procedures, which was assessed as the occurrence of complications during hospitalization. Postoperative pancreatic fistula (POPF) was classified as grade A, B, or C according to the International Study Group of Pancreatic Fistula classification. RESULTS We found that the incidence of POPF was 11.52%. With regard to POPF, the present study showed no significant difference in the two groups (p=0.043). The incidence of Grade C POPF was significantly higher in the PJ group than in the PG group (p=0.001), which was been reflected in the form of a higher rate of postoperative hemorrhage (p=0.001), intra-abdominal abscess (p=0.012), and septic shock (p=0.012) events in the PJ group. CONCLUSION The evaluation of short-term outcomes demonstrates that suturelessPG is a feasible and safe technique, associated with lower life-threatening complications than single-layer duct-to-mucosa PJ. If long-term functional outcomes confirm similar results, sutureless PG could become a valid alternative for pancreatic anastomosis after PD in patients with soft pancreas and high morbidity.

Abstract
The altered anatomy in patients after bariatric surgery who have undergone a Roux-en-Y gastric bypass may pose a technical challenge for surgical removal of the pancreatic head. We treat patients with pancreas cancer with multimodality therapy in a neoadjuvant fashion followed by pancreaticoduodenectomy (PD). In patients with Roux-en-Y gastric bypass anatomy, the gastric remnant is preserved and used for pancreaticogastrostomy reconstruction and subsequently drained by the same jejunal limb used for the hepaticojejunostomy. This method of reconstruction takes advantage of the previous surgically altered anatomy and avoids the morbidity of a gastric remnant resection at the time of PD.

Abstract
Pancreaticoduodenectomy is considered the standard operation for periampullary tumors. Despite major advances in pancreatic surgery, pancreatic fistula is still an important cause of morbidity and mortality after pancreaticoduodenectomy. Meticulous surgical technique and proper reconstruction of the pancreas are essential to prevent pancreatic fistula. Pancreaticogastrostomy is a safe method for reconstruction of the pancreas after pancreaticoduodenectomy. Regardless of pancreatic texture or duct diameter, the reconstruction is performed by passing full-thickness sutures through both the anterior and posterior sides of the pancreas. In this study, we report 39 cases of reconstruction with pancreaticogastrostomy after pancreaticoduodenectomy without mortality or pancreatic fistula.

Pancreaticogastrostomy has advantages over pancreaticojejunostomy on pancreatic fistula after pancreaticoduodenectomy. A meta-analysis of randomized controlled trials. Int J Surg 2016; 36:18-24. [PMID: 27768898 DOI: 10.1016/j.ijsu.2016.10.020] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2016] [Revised: 10/12/2016] [Accepted: 10/14/2016] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To examine whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is the better reconstructive method to reduce postoperative complications, especially pancreatic fistula (PF), after pancreaticoduodenectomy (PD). BACKGROUND PF is a severe complication after PD. The best reconstructive method to reduce occurrence of PF is controversial. We carried out this meta-analysis to compare PG with PJ. METHODS A systematic review was conducted on PubMed, EMBASE, and Cochrane Library published up to October 2015 to identify studies comparing PG with PJ. Postoperative complications and mortality were evaluated. A meta-analysis was carried out by Review Manager 5.0. RESULTS 10 RCTs representing 1629 patients (826 PG, 803 PJ) were included. There was a significant difference in favor of PG over PJ (OR 0.72, 95% CI 0.56-0.92, P = 0.009, I2 = 10%). No significant differences were found in biliary fistula (OR 0.58, 95% CI 0.31-1.06, P = 0.08, I2 = 38%), DGE (OR 1.08, 95% CI 0.68-1.70, P = 0.75, I2 = 53%), overall morbidity (OR 0.97, 95% CI 0.77-1.23, P = 0.82, I2 = 28%), and mortality (OR 0.98, 95% CI 0.60-1.61, P = 0.94, I2 = 0%). CONCLUSIONS The meta-analysis showed a significant difference between PG and PJ on PF: PG was associated with significantly less PF when compared to PJ, indicating that PG is superior to PJ for reconstruction after PD.

A novel technique of inserting pancreaticogastrostomy with duct-to-mucosa anastomosis can potentially reduce postoperative pancreatic fistula. J Surg Res 2016; 209:79-85. [PMID: 28032574 DOI: 10.1016/j.jss.2016.09.052] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2016] [Revised: 09/02/2016] [Accepted: 09/27/2016] [Indexed: 12/19/2022]
Abstract
BACKGROUND We describe our novel technique of inserting pancreaticogastrostomy (IPG) after pancreaticoduodenectomy. In our technique, the seromuscular and mucosal layers of the posterior gastric wall are separated to create a mucosal pouch. A duct-to-mucosa anastomosis is performed through a small incision in the mucosal layer. An inner suture at the seromuscular-mucosal margin incorporating the pancreatic parenchyma and an outer suture on the exterior margin of the seromuscular layer to wrap the pouch around the pancreas are placed to complete the IPG. MATERIALS AND METHODS We examined the clinicopathological features and outcomes of 259 patients who underwent pancreaticoduodenectomy between January 2010 and April 2014. RESULTS One hundred forty-three (55.2%) patients underwent IPG, while 116 (44.8%) had conventional pancreaticojejunostomy. Most preoperative and intraoperative parameters were comparable. Overall morbidity in the IPG group was 28.7%. The rate of grade A postoperative pancreatic fistula (POPF) was 7.0%, and the rates of grade B and C POPF were 0.7% and 0.0%, respectively. The corresponding rates of grade A, B, and C fistulae were 5.2%, 8.6%, and 5.2%, respectively. CONCLUSIONS In selected patients, our novel technique can be performed safely and may reduce the rates of POPF.

Pancreaticojejunostomy is comparable to pancreaticogastrostomy after pancreaticoduodenectomy: an updated meta-analysis of randomized controlled trials. Langenbecks Arch Surg 2016; 401:427-37. [PMID: 27102322 DOI: 10.1007/s00423-016-1418-z] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2015] [Accepted: 03/30/2016] [Indexed: 12/12/2022]
Abstract
PURPOSE To perform an up-to-date meta-analysis of randomized controlled trials (RCTs) comparing pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) in order to determine the safer anastomotic technique. Compared to existing meta-analysis, new RCTs were evaluated and subgroup analyses of different anastomotic techniques were carried out. METHODS We conducted a bibliographic research using the National Library of Medicine's PubMed database from January 1990 to July 2015 of RCTs. Only RCTs, in English, that compared PG versus all types of PJ were selected. Data were independently extracted by two authors. We performed a quantitative systematic review following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. A random-effect model was applied. Statistical heterogeneity was assessed using the I (2) and χ (2) tests. Primary outcomes were rate of overall and clinically significant pancreatic fistula (POPF). RESULTS Ten RCTs were identified including 1629 patients, 826 undergoing PG and 803 undergoing PJ. RCTs showed significant heterogeneity regarding definitions of POPF, perioperative management, and characteristics of pancreatic gland. No significant differences were found in the rate of overall and clinically significant POPF, morbidity, mortality, reoperation, and intra-abdominal sepsis when PG was compared with all types PJ or when subgroup analysis (double-layer PG with or without anterior gastrotomy versus duct to mucosa PJ and single-layer PG versus single-layer end-to-end/end-to-side PJ) were analyzed. CONCLUSIONS PG is not superior to PJ in the prevention of POPF. Current RCTs have major methodological limitations with significant heterogeneity in regard to surgical techniques, definition of POPF/complications, and perioperative management.

Abstract
One of the most common symptoms presenting in patients with chronic pancreatitis is pancreatic-type pain. Obstruction of the main pancreatic duct in chronic pancreatitis can be treated by a multitude of therapeutic approaches, ranging from pharmacologic, endoscopic and radiologic treatments to surgical interventions. When the conservative treatment approaches fail to resolve symptomatic cases, however, endoscopic retrograde pancreatography with pancreatic duct drainage is the preferred second approach, despite its well-recognized drawbacks. When the conventional transpapillary approach fails to achieve the necessary drainage, the patients may benefit from application of the less invasive endoscopic ultrasound (EUS)-guided pancreatic duct interventions. Here, we describe the case of a 42-year-old man who presented with severe abdominal pain that had lasted for 3 mo. Computed tomography scanning showed evidence of chronic obstructive pancreatitis with pancreatic duct stricture at genu. After conventional endoscopic retrograde pancreaticography failed to eliminate the symptoms, EUS-guided pancreaticogastrostomy (PGS) was applied using a fully covered, self-expandable, 10-mm diameter metallic stent. The treatment resolved the case and the patient experienced no adverse events. EUS-guided PGS with a regular biliary fully covered, self-expandable metallic stent effectively and safely treated pancreatic-type pain in chronic pancreatitis.

Inadvertent ligation of the main pancreatic duct: an extremely rare complication of choledochal cyst excision. Indian J Surg 2015; 77:92-3. [PMID: 25972658 DOI: 10.1007/s12262-014-1168-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2014] [Accepted: 09/11/2014] [Indexed: 10/24/2022] Open
Abstract
Pancreatic ductal injury is rare during choledochal cyst excision. Most cases present in the immediate postoperative period with pancreatic fistula or acute pancreatitis are managed conservatively. But, inadvertent ligation of the main pancreatic duct with subsequent recurrent pancreatitis and upstream dilatation of the pancreatic duct requiring a pancreatic ductal drainage operation has not been reported in the English literature. A 23-year-old female patient presented with recurrent episodes of upper abdominal pain for about 16 months. She had a history of type-1 choledochal cyst excision 18 months back. She was evaluated with abdominal ultrasound and magnetic resonance cholangiopancreatography (MRCP). MRCP showed hugely dilated main pancreatic duct with normal hepaticojejunostomy anastomosis. There was no residual cyst. MRCP findings were suggestive of stricture of the main pancreatic duct due to previous surgery. Endoscopic pancreatic ductal decompression failed. The patient was treated successfully with pancreaticogastrostomy. Postoperative recovery was uneventful. The patient was well at 24-month follow-up.

A novel pancreaticogastrostomy method using only two transpancreatic sutures: early postoperative surgical results compared with conventional pancreaticojejunostomy. Ann Surg Treat Res 2015; 88:299-305.

Abstract
Purpose To evaluate the surgical outcomes of pancreaticogastrostomy (PG) using two transpancreatic sutures with a buttress method through an anterior gastrostomy (PGt), and compare these results with our previous experience with pancreaticojejunostomy (PJ) including the dunking and duct to mucosa methods after pancreaticoduodenectomy (PD). Methods In this study, 171 patients who had undergone PD between January 2005 and April 2013 were classified into three groups according to the method of the pancreaticoenteric anastomosis: dunking PJ (PJu group; n = 67, 39.1%), duct to mucosa PJ (PJm group; n = 41, 23.9%), and PGt (PGt group; n = 63, 36.8%). We retrospectively analyzed patient characteristics, perioperative outcomes, and surgical results. Results Both groups had comparable demographics and pathology, and there were no significant differences in operative time, estimated blood loss, or postoperative hospital stay. Within the two groups, morbidities occurred in 49 cases (10.7%), and were not significantly different between the two groups, excepting postoperative pancreatic fistula (POPF). The PGt group had a lower rate of POPF (18/63, 28.6%) than the PJu and PJm groups (21/67, 31.3% and 19/41, 46.3%; P = 0.048), especially in terms of grades B and C POPF (4/63 [6.3%] in the PGt group vs. 7/67 [10.4%] in the PJu group and 9/41 [22.0%] in the PJm group, P = 0.049). Conclusion The PGt method showed feasible outcomes for POPF and had advantages over dunking PJ and duct to mucosa PJ with respect to immediate postoperative results. PGt may be a promising technique for pancreaticoenteric anastomosis after PD.

Abstract
BACKGROUND The best reconstruction method for the pancreatic remnant after pancreaticoduodenectomy remains debatable. We aimed to investigate the perioperative outcomes of 2 popular reconstruction methods: pancreaticogastrostomy and pancreaticojejunostomy. DATA SOURCES Randomized controlled trials comparing pancreaticogastrostomy versus pancreaticojejunostomy were identified from literature databases (MEDLINE/PubMed, EMBASE, Web of Science, Cochrane Library). The meta-analysis included 8 studies: 607 patients who underwent pancreaticogastrostomy and 604 who underwent pancreaticojejunostomy. Postoperative pancreatic fistula and intra-abdominal fluid collection rates were significantly lower after pancreaticogastrostomy compared with pancreaticojejunostomy. No statistically significant differences were found in the incidence of delayed gastric emptying, biliary fistula, hemorrhage, reoperation, wound infection, overall morbidity, mortality, and length of hospital stay. CONCLUSIONS Our meta-analysis suggests that pancreaticogastrostomy not only reduces the rate of postoperative pancreatic fistula but also decreases its severity. Pancreaticogastrostomy is associated with a lower rate of intra-abdominal fluid collection. Our results suggest that pancreaticogastrostomy should be the preferred reconstruction method.

Abstract
With the advance of laparoscopic experiences and techniques, it is carefully regarded that laparoscopic pancreaticoduodenectomy (lap-PD) is feasible and safe in managing perimapullary pancreatic pathology. Especially, laparoscopic management of remnant pancreas can be a critical step toward completeness of minimally invasive PD. According to available published reports, there is a wide range of technical differences in choosing surgical options in managing remnant pancreas after lap-PD. For the evidence-based surgical approach, it would be ideal to test potential techniques by randomized controlled trials, but, currently, it is thought to be very difficult to expect those clinical trials to be successful because there are still a lack of expert surgeons with sound surgical techniques and experience. In addition, lap-PD is so complicated and technically demanding that many surgeons are still questioning whether this surgical approach could be standardized and popular like laparoscopic cholecystectomy. In general, surgical options are usually chosen based on following question: (1) Is it simple? (2) Is it easy and feasible? (3) Is it secure and safe? (4) Is there any supporting scientific evidence? It would be interesting to estimate which surgical technique would be appropriate in managing remnant pancreas under these considerations. It is hoped that a well standardized multicenter-based randomized control study would be successful to test this fundamental issues based on sound surgical techniques and scientific background.

Abstract
The pancreaticoduodenectomy (PD) procedure may lead to pancreatic exocrine and endocrine insufficiency. There are several types of reconstruction for this kind of operation. Pancreaticogastrostomy (PG) was introduced to reduce the rate of postoperative pancreatic fistula. Although some randomized control trials have shown no differences regarding pancreatic leakage between PG and pancreaticojejunostomy (PJ), recently some reports reveal benefits from the PG over the PJ. Some surgeons concern about the performing of the PG and inactivation of pancreatic enzymes being in contact with the gastric juice, and the detrimental results over the exocrine pancreatic function. The pancreatic exocrine function can be measured with direct and indirect tests. Direct tests have the highest sensitivity and specificity for detection of exocrine insufficiency but require tube placement. Among the tubeless indirect tests, the van de Kamer stool fat analysis remains the standard to diagnose fat malabsorption. The patient compliance and time consuming makes it not so suitable for its clinical use. Fecal immunoreactive elastase test is employed for screening of exocrine insufficiency, is not cumbersome, and has been used to study pancreatic function after resection. We analyze the FE1 levels in our patients after the PD with two types of reconstruction, PG and PJ, and we discuss some considerations about the pancreaticointestinal drainage method after pancreaticoduodenectomy.

Abstract
INTRODUCTION Fast track programmes have been introduced in pancreatic surgery, but the data are sparse. The aim of this prospective study was to analyse the feasibility of implementing fast track rehabilitation protocol in PD with pancreaticogastrostomy, using historical control for comparison. MATERIALS AND METHODS Between April 2012 and December 2012, twenty patients who underwent PD (with pancreaticogastrostomy) were managed by a fast-track rehabilitation protocol. These patients were compared with an equal number of historical controls treated according to the traditional protocol. RESULTS Patients in the fast track group were able to tolerate liquid (p = 0.0005) and solid diet (p = 0.0001) earlier, and they passed stools earlier (p = 0.02). Delayed gastric emptying (DGE) was significantly reduced in the fast track group (p = 0.02). There was no difference in the rates of pancreatic fistula (PF), post pancreatectomy haemorrhage (PPH) and mortality between the two groups. Length of hospital stay was reduced in the fast track group (median 14 vs 18.5, p = 0.007). CONCLUSION Fast track programme appears to be feasible in PD, even with pancreatico-gastric anastomosis. It is associated with early recovery, reduced DGE and reduced hospital stay.

Abstract
Techniques for reconstruction of pancreatic stump with gastrointestinal tract following pancreaticoduodenectomy are closely related to postoperative complications, mortality and quality of life. In order to reduce postoperative complications, particularly pancreatic fistula, many modifications and new surgical techniques have been proposed to replace the traditional pancreaticojejunostomy and pancreaticogastrostomy. The objective of this review, based on large prospective randomized trials and meta-analyses, is to evaluate the different techniques of enteric reconstruction of pancreatic stump following pancreaticoduodenectomy, including: invagination pancreaticojejunostomy, binding pancreaticojejunostomy, duct-to-mucosa pancreaticojejunostomy, Roux-en-Y pancreaticojejunostomy, and pancreaticogastrostomy, so as to provide a comprehensive comparison of these techniques and to assess of their roles and effectiveness.

Abstract
BACKGROUND It has long been debated whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is the better choice for reconstruction after pancreaticoduodenectomy. The purpose of this study is to evaluate the two techniques. METHODS Randomized controlled trials (RCTs) comparing PG with PJ published from January 1995 to January 2014 were searched electronically using PubMed, Medline, and Cochrane Library. Published data of these RCTs were analyzed using either fixed-effects model or random-effects model. RESULTS Seven RCTs were included in this meta-analysis, with a total of 1121 patients (562 in PG, 559 in PJ). The incidence of postoperative pancreatic fistula and intra-abdominal fluid collection were significantly lower in PG than in PJ (respectively: odds ratio = 0.53 [0.37, 0.74], P < 0.001; odds ratio = 0.48 [0.30, 0.76], P < 0.01), no significant difference could be found for delayed gastric emptying, hemorrhage, morbidity, reoperation rate, and mortality. CONCLUSIONS The evidence from RCTs suggests that PG technique is associated with a lower rate of postoperative pancreatic fistula and intra-abdominal fluid collection than PJ.

Abstract
Desmoid tumors (DTs) are nonmetastatic, locally aggressive neoplasms with a high rate of postoperative recurrence. Pancreatic DTs are especially rare; only a few cases have been reported to date. This paper describes a case of a sporadic cystic DT of the pancreas managed successfully with central pancreatectomy, with no signs of recurrence 40 mo after surgery. According to the literature, this is the first reported case in China of a pancreatic DT presenting as a solid cystic lesion, as well as the first pancreatic DT managed with central pancreatectomy and pancreaticogastrostomy. We report the case for its rarity and emphasize disease management by concerted application of clinical, pathological, radiological and immunohistochemical analyses.

Abstract
Over the last 2 decades there has been continuing development in endoscopic ultrasonography (EUS). EUS-guided pancreatic drainage is an evolving procedure that can be offered to patients who are high-risk surgical candidates and in whom the pancreatic duct cannot be accessed by endoscopic retrograde pancreatography. Although EUS-guided pancreatic drainage is a minimally invasive alternative option to surgery and interventional radiology, owing to its complexity and potential for fulminant complications it is recommended that these procedures be performed by highly skilled endoscopists. Additional data are needed to define risks and long-term outcomes more accurately via a dedicated prospective registry.

Abstract
Pancreaticoenteric anastomotic stricture can occur as a late complication of pancreatic head resection and is difficult to manage. The surgically altered anatomies of patients that have undergone pancreatic head resection make it difficult to perform pancreatic duct drainage using conventional endoscopes, and it is especially difficult to endoscopically identify stenotic pancreaticojejunal anastomoses. A 40-year-old woman was referred to our department for the treatment of symptomatic multiple pancreatic stones and anastomotic stricture after end-to-side pancreaticojejunostomy. Endoscopic ultrasound-guided pancreaticogastrostomy was performed in an attempt to avoid re-surgery. At 18 days after the initial procedure, a guidewire was successfully placed in the jejunum through the anastomotic stricture. The anastomotic stricture was dilated using a dilation balloon, and all of the stones were pushed into the jejunum using a retrieval balloon. No complications were experienced during the procedure. At 22 months after the stone removal, the main pancreatic duct displayed a decreased diameter, and no stone recurrence was detected.

Abstract
Abstract The purpose of this analysis was to evaluate the technological viability, basic safety and consequence of central pancreatectomy (CP) with pancreaticogastrostomy in properly chosen sufferers with noncancerous central pancreatic pathology. This research is centered on the infirmary charts of West China hospital. We recruited 20 individuals from 2007 to 2009 diagnosed with benign cancerous growth of pancreatic body and neck. They underwent pancreatic body and neck resection adhering to pancreaticogastrostomy. We carried out central pancreatectomy following pancreaticogastrostomy in 20 patients: 8 with serous cyst adenomas, 11 with mucinous cystadenomas, and 1 with neuroendocrine tumor. The position of all tumors was restricted to body and neck of the pancreas, measuring a mean ± standard deviation of 2.6±1.3cm. The mean post-operative hospital stay was 7 days (ranging from 6 to 16 days).There was no intraoperative additional complications. From a technical perspective, CP is a safe and sound, pancreas-preserving pancreatectomy for non-enucleable non-cancerous pancreatic pathology restricted to the pancreatic body.

Abstract
Pancreatic fistula is the most serious postoperative complication after pancreaticoduodenectomy, and it leads to intra-abdominal abscess, sepsis, hemorrhage and high mortality. To prevent pancreatic fistula, wrapping of skeletonized vessels and the anastomotic site of the pancreaticoenterostomy using the round ligament, greater omentum, or both has been evaluated. However, the round ligament and greater omentum have already been resected in patients who have previously undergone total gastrectomy, making them unavailable in pancreaticoduodenectomy. Therefore, we developed a procedure for wrapping the anastomotic site of the pancreaticojejunostomy using the jejunum, namely the 'jejunal scarf-covering method' as a novel technique to prevent pancreatic fistula following pancreaticoduodenectomy in patients who have previously undergone total gastrectomy.

Abstract
AIM: To investigate the safety and efficacy of modified pancreaticogastrostomy (PG) for digestive tract reconstruction after pancreaticoduodenectomy (PD).
METHODS: A total of 44 patients who underwent modified PG after PD at our hospital from March 2006 to July 2009 were retrospectively analyzed.
RESULTS: The mean operation time was 260 min (range: 200-420 min). The mean blood loss was 260 mL (range: 150-1600 mL). No mortality occurred postoperatively. The postoperative pancreatic leakage occurred in 2 patients (4.55%, 2/44), both of which were cured by conservative management. Delayed gastric emptying occurred in 5 patients (11.36%, 5/44). The bleeding of the pancreatic stump occurred in 1 patient (2.27%, 1/44). No surgical wound infection or abdominal infection occurred. The mean postoperative length of stay (LOS) was 15 days (range: 13-27 days). The postoperative follow-up, which lasted from 3 months to 3 years, was carried out in all patients, and no long-term complications were found.
CONCLUSION: Modified PG after PD is a safe and easy procedure for digestive tract reconstruction.
