OGC SO37 - Pyloric drainage interventions for delayed gastric conduit emptying after oesophagectomy: A single centre analysis

Abstract Background Oesophagectomy in combination with perioperative multimodal therapy is the cornerstone of modern curative treatment for resectable oesophageal cancer. Delayed gastric emptying (DGE) is a common postoperative complication that results from the anatomical and physiological changes in the gastric conduit after an oesophageal resection. It is associated with an increased risk of pneumonia, anastomotic leak and prolonged hospital stay. Although several prophylactic pyloric drainage interventions have been postulated to mitigate the risk of DGE, the optimal modality remains debatable. This study aimed to define the incidence, evaluate prognostic factors, and characterise the management of DGE following oesophagectomy. Method Consecutive patients who underwent an oesophagectomy for oesophageal cancer between January 2022 and March 2024 were retrospectively identified from a hospital database. Pyloric drainage procedures consisted of expectant management, endoscopic/open pyloric Botox and pyloroplasty. Univariable and multivariable analyses were performed to define the incidence of DGE after each pyloric drainage modality, evaluate prognostic factors for DGE, and characterise the need for subsequent intervention in the management of DGE. Results The study cohort comprised 137 patients – mean age 66 years, male 78%. The incidence of DGE was 31%. Pyloroplasty had the lowest incidence of DGE (16%) followed by endoscopic botox (21%). Intra-operative pyloric drainage reduced the risk of DGE (p=0.03). The modality of prophylactic pyloric drainage used significantly influenced the risk of developing DGE (p=0.028). No significant differences were identified between patient demographics, operative approach, and oncological variables in the development of DGE. On multivariable analysis, pyloroplasty was associated with a reduced risk of DGE (OR 0.27, 95% CI 0.09 – 0.71). DGE did not influence overall survival. Conclusion DGE is a common postoperative complication which affects up to 39% of patients undergoing oesophagectomy. Patients who did not undergo a prophylactic pyloric drainage procedure during the index oesophagectomy were at an increased risk of developing DGE. Most patients with DGE (71%) require further intervention via endoscopy and botox injection. Pyloroplasty as a prophylactic drainage modality significantly reduced the risk of developing DGE compared to endoscopic botox. Further prospective randomised controlled trials are required to validate these findings.

The Association Between Preoperative Sarcopenia and Sarcopenic Obesity and the Occurrence of Postoperative Complications in Patients Undergoing Pancreaticoduodenectomy for Periampullary Malignancies-A Literature Review.

Sarcopenia and sarcopenic obesity, perceived as a reflection of cancer-induced cachexia, are often diagnosed in patients with periampullary malignancies. The pathophysiology of those conditions is multifactorial regarding the tumor microenvironment, immunological response, and the relationship to surrounding tissues. The PubMed and SCOPUS databases were systematically searched between November 2023 and December 2023. A total of 254 studies were primarily identified. Regarding the inclusion and exclusion criteria, 26 studies were finally included in the review. Evaluated papers disclosed that sarcopenia was significantly associated with a higher incidence of postoperative complications, including pancreatic fistula (POPF) type B and C, with the odds ratio (OR) ranging from 2.65 (95%CI 1.43-4.93, p = 0.002) to 4.30 (95%CI 1.15-16.01, p < 0.03). Sarcopenic patients also suffered more often from delayed gastric emptying (DGE) with an OR of 6.04 (95%CI 1.13-32.32, p = 0.036). Infectious complications, postoperative hemorrhage, and intra-abdominal abscesses occurred more often in sarcopenic patients. Surgical complications were also noted more frequently when sarcopenic obesity was present. Preoperative nutritional prehabilitation seems to reduce the risk of postoperative complications. However, more prospective studies are needed. Sarcopenia and sarcopenic obesity were associated with a higher incidence of multiple postoperative complications, including POPF (type B and C), DGE, hemorrhage, and infectious complications.

Primary delayed gastric emptying after pylorus-resecting pancreatoduodenectomy: A matched-pair comparison of Roux-en-Y vs. Billroth-II reconstruction

BackgroundAfter pylorus-resecting pancreatoduodenectomy (PrPD), delayed gastric emptying (DGE) might partially be attributed to biliary reflux. We investigated whether the incidence of primary DGE is reduced after Roux-en-Y instead of Billroth-II reconstruction. MethodsPatients undergoing PrPD from 2016 to 2019 at a high-volume center were identified. Excluding causes of secondary DGE, we matched patients with Roux-en-Y and Billroth-II reconstruction in a 1:2 ratio and compared primary DGE. ResultsIn 24 vs. 48 (Roux-en-Y vs. Billroth-II) patients, DGE (grade B/C) incidence (20.8 % vs. 18.8 %; p = 1.000), nasogastric tube requirement (median 2 vs. 2 days; p = 0.844) and time to solid food intake (7 vs. 7 days; P = 0.933) were comparable. Univariable logistic regression showed no association between DGE and Roux-en-Y reconstruction (OR 1.47; p = 0.524), in contrast to age (1.08; P = 0.030) and pancreatic biochemical leak (4.98; p = 0.007). ConclusionsPrimary DGE did not differ between Roux-en-Y and Billroth-II reconstruction after PrPD. Instead, age and postoperative pancreatic biochemical leak were associated with higher DGE risk.

Impact of marmara-yegen cuttıng gastrojejunostomy on delayed gastrıc emptyıng after pancreatoduodenectomy: ınıtıal results.

Delayed gastric emptying (DGE) is one of the most common reasons for morbidity after pancreatoduodenectomy. The technical characteristics of anastomosis that could be affected by surgeon may offer a relevant chance to improve postoperative DGE rates. We investigated the effect of a technical modification of gastrojejunostomy after the classical pancreaticoduodenectomy on DGE. A total of 161 patients underwent classical pancreaticoduodenectomy (with 20-40 percent antrectomy) due to pancreatic adenocarcinoma at the Department of General Surgery, Marmara University, School of Medicine Hospital, from February 2019 to May 2023, and those who met the inclusion criteria were enrolled. One hundred twenty patients had undergone classical end-to-side gastrojejunostomy (Classical GJ group), and 41 had undergone Marmara-Yegen cutting side-to-side gastrojejunostomy (M-Yc group). DGE was defined according to the International Working Group on Pancreatic Surgery, and postoperative DGE rates of both groups were compared. In addition, multivariate analysis was performed to identify possible independent predictive factors for DGE. The total incidence of DGE was 31% in the Classical GJ group and 17% in the (M-Yc group). Although there was no significant difference between the groups regarding DGE and DGE grades (p = 0.1), DGE was distinctly lower in the M-Yc GJ group. In multi-variant analysis, Clavien-Dindo grade 3a and above postoperative complication was determined as independent predictors for DGE. We tried to explain the mechanism of DGE in terms of anatomical configuration. The incidence and severity of DGE decreased in patients who underwent M-Yc GJ.

Delayed Gastric Emptying and Other Adverse Outcomes in Patients Undergoing Classic Whipple Versus Pylorus-Sparing Pancreatoduodenectomy.

Background and objective Pancreatoduodenectomy (PD), or the Whipple procedure, has many variants. There is a lack of data in the literature in terms of comparing various types of this procedure. This study aimed to comparethe classic Whipple procedure with the pylorus-sparing Transverso-Longmire technique, focusing on postoperative complications and delayed gastric emptying (DGE). Methodology We conducted a retrospective observational study including 97 adult patients who underwent either the classic Whipple procedure or the pylorus-sparing technique at Hospital Médica Sur from 2016 to 2021. Data on patient demographics, comorbidities, type of surgery, clinical presentation, and postoperative complications were collected. DGE was defined according to the International Study Group of Pancreatic Surgery(ISGPS) criteria. Results Among the 97 patients, 50.5% were men, and the median age of the cohort was 65 years. Almost all patients underwent surgery for malignancy (96.9%). The classic Whipple group had fewer cases of DGE (9.8% vs. 30.6%, p=0.01), shorter hospital stays (7 vs. 11 days, p=0.001), and lower readmission rates (13.1% vs. 33.3%, p=0.017). The pylorus-sparing PD was associated with a lower incidence of bile leak [odds ratio (OR)=0.62, 95% confidence interval (CI): 0.53-0.73]. However, this technique was associated with a higher incidence of DGE (OR=4, 95% CI: 1.34-12.1), overall hospital admission rates (OR=3.3, 95% CI: 1.2-9.2), and admissions that resulted in a surgical event (OR=1.9, 95% CI: 1.21-2.96). DGE was associated with the need for a second surgery (OR=10.5, 95% CI: 2.8-39.5) and hospital readmission (OR=10, 95% CI: 3.1-32.3). Conclusions While the pylorus-sparing technique is associated with reduced bile leaks, it results in a higher incidence of DGE, prolonged hospital stays, and increased readmissions. Clinicians opting for the pylorus-sparing technique should ensure careful patient selection and rigorous postoperative monitoring.

Intra-operative pyloric BOTOX injection versus pyloric surgery for prevention of delayed gastric emptying after esophagectomy.

Delayed gastric emptying (DGE) is a common complication after esophagectomy. BOTOX injections and pyloric surgeries (PS), including pyloroplasty (PP) and pyloromyotomy (PM), are performed intraoperatively as prophylaxis against DGE. This study compares the effects of pyloric BOTOX injection and PS for preventing DGE post-esophagectomy. We retrospectively reviewed Moffitt's IRB-approved database of 1364 esophagectomies, identifying 475 patients receiving BOTOX or PS during esophageal resection. PS was further divided into PP and PM. Demographics, clinical characteristics, and postoperative outcomes were compared using Chi-Square, Fisher's exact test, Wilcoxon rank-sum, and ANOVA. Propensity-score matching was performed between BOTOX and PP cohorts. 238 patients received BOTOX, 108 received PP, and 129 received PM. Most BOTOX patients underwent fully minimally invasive robotic Ivor-Lewis esophagectomy (81.1% vs 1.7%) while most PS patients underwent hybrid open/Robotic Ivor-Lewis esophagectomy (95.7% vs 13.0%). Anastomotic leak (p = 0.57) and pneumonia (p = 0.75) were comparable between groups. However, PS experienced lower DGE rates (15.9% vs 9.3%; p = 0.04) while BOTOX patients had less postoperative weight loss (9.7 vs 11.45kg; p = 0.02). After separating PP from PM, leak (p = 0.72) and pneumonia (p = 0.07) rates remained similar. However, PP patients had the lowest DGE incidence (1.9% vs 15.7% vs 15.9%; p = < 0.001) and the highest bile reflux rates (2.8% vs 0% vs 0.4%; p = 0.04). Between matched cohorts of 91 patients, PP had lower DGE rates (18.7% vs 1.1%; p = < 0.001) and less weight loss (9.8 vs 11.4kg; p = < 0.001). Other complications were comparable (all p > 0.05). BOTOX was consistently associated with shorter LOS compared to PS (all p = < 0.001). PP demonstrates lower rates of DGE in unmatched and matched analyses. Compared to BOTOX, PS is linked to reduced DGE rates. While BOTOX is associated with more favorable LOS, this may be attributable to difference in operative approach. PP improves DGE rates after esophagectomy without improving other postoperative complications.

Impact of Straight Stomach Reconstruction on Delayed Gastric Emptying and Nutritional Recovery After Pancreaticoduodenectomy.

The aim of this study was to evaluate the effectiveness of a modified reconstruction technique-anchored straight stomach reconstruction-in reducing the incidence of delayed gastric emptying (DGE) after pancreaticoduodenectomy (PD) and its impact on postoperative nutritional recovery. A case series analysis of 125 consecutive PD patients was conducted: 104 of them had undergone anchored straight stomach reconstruction (SSR group) and the remaining 21 without (Non-SSR group). The incidence of DGE and the change in postoperative nutritional status (body weight and serum albumin level during 12months post-surgery) were compared. The incidence of DGE in the SSR group (13%) was significantly lower than that in the Non-SSR group (33%) (P = .018); further the significant DGE (grade B or C) was only 5%. Comparison of nutritional status showed that SSR facilitated a prompt recovery of body weight and serum albumin level at 6months after PD. At 12months after surgery, body weight gain was significantly better in the SSR group than in the Non-SSR group (P = .006), and albumin level tended to be higher in the SSR group (P = .071). Straight stomach reconstruction is able to reduce DGE in patients after PD and also improves their postoperative nutritional recovery.

Utility of gastrostomy tube placement at the time of pancreaticoduodenectomy.

The aim of this study is to investigate the utility of gastrostomy tube (G-tube) placement in reducing delayed gastric emptying (DGE) among patients undergoing pancreaticoduodenectomy (PD). We retrospectively reviewed consecutive patients undergoing PD from 2015 to 2020 at our institution. Thirty-day patient outcomes including DGE, length of stay (LOS), reoperation rates, and morbidity were analyzed in patients with or without G-tube placement. 128 patients with resectable pancreatic head cancer (54 females, median age 68.50 [59.00-74.00]) underwent PD (66 had G-tube placement and 62 did not). There was no significant difference in the incidence of DGE (n = 17 vs. n = 17, p = 0.612), and LOS between the groups. Postoperative ileus (p = 0.007) was significantly lower while atrial fibrillation (p = 0.037) was higher among the G-tube group. Gastrostomy-related complications (p = 0.001) developed in ten patients: skin-related complications (n = 6), tube dislodgement (n = 3) and clogging (n = 1). Nine patients required reoperation during index admission (n = 4 vs. n = 5, p = 1.000). There was no difference in 30-day readmissions (n = 7 vs. n = 5, p = 0.471) and no difference in 30 or 90-day mortality. Gastrostomy tube placement during index PD did not affect the incidence of DGE. However, patients experienced significant morbidities due to G-tube-related complications. Placement of gastrostomy tubes at the index PD offers no clinical benefits.

Impact of posterior wall gastrojejunostomy versus anterior wall gastrojejunostomy in pancreaticoduodenectomy on delayed gastric emptying and enhanced recovery: a prospective study

Background Pancreaticoduodenectomy (Whipple operation) is considered the main surgical management for duodenal, pancreatic head, and lower end common bile duct neoplasm. Gastrojejunostomy orientation has a direct impact on enteral feeding and delayed gastric emptying (DGE). Aim The primary outcomes were reviewing the effect of changing the orientation of gastrojejunostomy either anterior wall vertical gastrojejunostomy versus posterior wall vertical gastrojejunostomy on DGE, early enteral feeding, leakage, and overall enhanced recovery with early start of chemotherapy. Patients and methods A prospective randomized trial 55 patients total number of patients after substraction of lost follow up was 50 patients and were divided into two group; group A: 27 patients underwent posterior wall gastrojejunostomy and group B: 23 patients underwent anterior wall gastrojejunostomy both techniques done in antecolic vertical manner. Results Operative time, postoperative bleeding, and leakage was not significantly different between the two groups. The total incidence of DGE was significantly lower in group A (posterior wall vertical) than group B (anterior wall vertical), regarding grades of DGE grade a was significantly lower in group A while the incidence in grades B and C was not significantly different regarding the number of patients. Ryle removal and starting oral intake was earlier and statistically significant in posterior wall vertical gastrojejunostomy when compared to anterior wall vertical gastrojejunostomy. Readmission, the actual use of prokinetics and need for nutritional support was higher in group B (anterior wall vertical gastrojejunostomy) than group A (posterior wall vertical gastrojejunostomy) but was not statistically significant. Conclusions Posterior wall vertical gastrojejunostomy has a better overall significant better outcome regarding early enteral feeding and DGE over anterior wall vertical gastrojejunostomy group also has better enhanced recovery and earlier time of starting chemotherapy. This topic should be evaluated in depth in a large-volume studies.

Stomach-partitioning versus conventional gastrojejunostomy for unresectable gastric cancer with gastric outlet obstruction: A propensity score matched cohort study

BackgroundStomach partitioning gastrojejunostomy (SPGJ) was introduced to deal with delayed gastric emptying (DGE). This study aimed to compare the short- and long-term outcomes of SPGJ versus conventional gastrojejunostomy (CGJ). MethodThis cohort study analyzed 108 patients who underwent gastrojejunostomy for unresectable gastric cancer: 70 patients underwent SPGJ, and 38 patients underwent CGJ between 2018 and 2022. Propensity score-matched (PSM) analysis was used to balance the baseline characteristics. ResultsAfter PSM, there were 26 patients in each group. SPGJ group had significantly lower incidence of DGE (3.8% vs. 34.6%), vomiting (3.8% vs. 42.3%), and prokinetics requirement (11.5% vs. 46.2%). SPGJ group had significantly shorter time to solid diet tolerance (4.1 days vs. 5.7 days) and postoperative hospital stay (7.7 days vs. 9.3 days). There was no significant difference in relapse reinterventions, gastric outlet obstruction (GOO) recurrence, conversion surgery, and survival outcomes. ConclusionsSGPJ was associated with lower rate of DGE, prokinetics requirement, and shorter time of solid diet tolerance compared to CGJ in the treatment of unresectable gastric cancer patients with GOO.

Delayed gastric emptying after pylorus-preserving pancreatoduodenectomy: Comparison between traditional open surgery and full-robotic approach with da Vinci Xi.

Delayed gastric emptying (DGE) is a frequent complication after pancreatoduodenectomy, especially after pylorus preservation (Pp). We evaluated the effect of a fully robotic approach with da Vinci Xi on DGE after PpPD. Open and robotic PDs were performed in 353 and 50 cases, respectively, from January 2009 to March 2022. We compared the clinical outcomes and incidence of clinically relevant DGE between robotic PpPD (R-PpPD) and open PpPD after one-to-one case-control matching. Each group consisted of 30 patients. Clinically relevant DGE was less common after R-PpPD (3/30 [10%] vs. 10/30 cases [33.3%], p=0.028). The median length of hospital stay (LoS) was significantly lower in the R-PpPD group (10 vs. 15days, p=0.013). The reduced tissue trauma by the minimally invasive robotic approach is associated with a lower incidence of DGE, reducing the LoS and encouraging PpPD performed using the fully robotic approach.

SP2.7 Is routine nasogastric tube placement following pancreatoduodenectomy really necessary?

Abstract Background Traditionally, pancreatoduodenectomy (PD) patients would leave theatre with a nasogastric tube (NGT) in situ. Recent evidence has suggested that the potential drawbacks of routine placement may outweigh the potential gains. This study aimed to compare the outcomes of PD patients who received a NGT intra-operatively to those did not. Methods Data taken from Recurrence After Whipple’s (RAW) study, a multicentre retrospective cohort study of outcomes of PD performed for pancreatic head malignancy (29 centres from 8 countries, n=1484). The following outcome measures were used: median length of stay (LoS), incidence of delayed gastric emptying (DGE), incidence of grade B/C DGE, and the provision of postoperative nutritional support. Analyses were performed using Fisher’s exact test and the Mann-Whitney U test. Results Out of 1484 patients who underwent PD for malignancy, 1098 (74.0%) had data on their NGT status. 91.6% of patients received an intra-operative NGT. The median length of time until tube removal was four days (range: 1-64, interquartile range: 3). in comparison to the group with no NG tube, median length of stay (both 14 days, p=0.9), as well as incidence of DGE (14.3% vs 7.6%, p=0.08) grade B/C DGE (8.3% vs 4.3%, p=0.2) were similar. Patients who did not receive a tube less often received postoperative nutritional support (any form, 30.4% vs 49.8%, p=0.0004). Conclusion Most patients underwent PD had NG placed intraoperatively. Had no affect length of stay or incidence of DGE. Patients who received a NGT more often received postoperative nutritional support. NGTs should only be placed when they are clinically indicated.

Risk factors of delayed gastric emptying in patients after pancreaticoduodenectomy: a comprehensive systematic review and meta-analysis.

Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy (PD) or pylorus-preserving pancreaticoduodenectomy (PPPD). However, its risk factors are still unclear. This meta-analysis aimed to identify the potential risk factors of DGE among patients undergoing PD or PPPD. We searched PubMed, EMBASE, Web of Science, Cochrane Library, Google Scholar, and ClinicalTrial.gov for studies that examined the clinical risk factors of DGE after PD or PPPD from inception through 31 July 2022. We pooled odds ratios (ORs) with 95% CIs using random-effects or fixed-effects models. We also performed heterogeneity, sensitivity, and publication bias analyses. The study included a total of 31 research studies, which involved 9205 patients. The pooled analysis indicated that out of 16 nonsurgical-related risk factors, three risk factors were found to be associated with an increased incidence of DGE. These risk factors were older age (OR 1.37, P =0.005), preoperative biliary drainage (OR 1.34, P =0.006), and soft pancreas texture (OR 1.23, P =0.04). On the other hand, patients with dilated pancreatic duct (OR 0.59, P =0.005) had a decreased risk of DGE. Among 12 operation-related risk factors, more blood loss (OR 1.33, P =0.01), postoperative pancreatic fistula (POPF) (OR 2.09, P <0.001), intra-abdominal collection (OR 3.58, P =0.001), and intra-abdominal abscess (OR 3.06, P <0.0001) were more likely to cause DGE. However, our data also revealed 20 factors did not support stimulative factors influencing DGE. Age, preoperative biliary drainage, pancreas texture, pancreatic duct size, blood loss, POPF, intra-abdominal collection, and intra-abdominal abscess are significantly associated with DGE. This meta-analysis may have utility in guiding clinical practice for improvements in screening patients with a high risk of DGE and selecting appropriate treatment measures.

The Effect of immunonutrition in patients undergoing pancreaticoduodenectomy: a systematic review and meta-analysis

BackgroundPancreaticoduodenectomy (PD) is a complex and traumatic abdominal surgery with a high risk of postoperative complications. Nutritional support, including immunonutrition (IMN) with added glutamine, arginine, and ω-3 polyunsaturated fatty acids, can improve patients’ prognosis by regulating postoperative inflammatory response. However, the effects of IMN on PD patients’ outcomes require further investigation.MethodsPMC, EMbase, web of science databases were used to search literatures related to IMN and PD. Data such as length of hospital stay, infectious complications, non-infectious complications, postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), mortality, systemic inflammatory response syndrome (SIRS) duration, IL-6, and C-reactive protein (CRP) were extracted, and meta-analyses were performed on these data to study their pooled results, heterogeneity, and publication bias.ResultsThis meta-analysis involved 10 studies and a total of 572 patients. The results showed that the use of IMN significantly reduced the length of hospital stay for PD patients (MD = -2.31; 95% CI = -4.43, -0.18; P = 0.03) with low heterogeneity. Additionally, the incidence of infectious complications was significantly reduced (MD = 0.42; 95% CI = 0.18, 1.00, P = 0.05), with low heterogeneity after excluding one study. However, there was no significant impact on non-infectious complications, the incidence of POPF and DGE, mortality rates, duration of SIRS, levels of IL-6 and CRP.ConclusionThe use of IMN has been shown to significantly shorten hospital stays and decrease the frequency of infectious complications in PD patients. Early implementation of IMN is recommended for those undergoing PD. However, further research is needed to fully assess the impact of IMN on PD patients through larger and higher-quality studies.

Delayed gastric emptying after aggressive surgery for retroperitoneal sarcoma - Incidence, characteristics, and risk factors.

Delayed gastric emptying (DGE) after aggressive resection of retroperitoneal sarcoma (RPS) has rarely been described. This study aimed to determine the incidence and characteristics of DGE after surgery for RPS and explore its potential risk factors. Patients with RPS who had undergone surgery between January 2010 and February 2021 were retrospectively analyzed. DGE was defined and graded according to the International Study Group of Pancreatic Surgery classification and classified as primary or secondary to other complications. Patients with clinically relevant DGE (crDGE, grade B+C) were compared to those with no or mild DGE (grade A). Multivariate logistic regression analysis of clinicopathological and surgical parameters was performed to identify risk factors for crDGE. Of the 239 patients studied, 69 (28.9%) had experienced DGE and 54 (22.6%) had experienced crDGE. Patients with primary and secondary DGE accounted approximately half and half. The most common concurrent complications included abdominal infection, postoperative pancreatic fistula, and abdominal bleeding. Patients with crDGE were more likely to have multifocal tumors and the liposarcoma subtype, with a larger tumor size, longer operating time, more resected organs, and a history of combined resection of the stomach, pancreas, small intestine, and/or colon. In multivariate analysis, the tumor size, operating time, and combined pancreatic resection were independent risk factors for crDGE. In conclusion, the current results indicated that approximately one-fourth of patients experienced DGE after aggressive surgery for RPS and that DGE was primary or secondary to other underlying conditions. A large tumor involving long, difficult surgery and combined pancreatic resection highly predicted the incidence of crDGE. The prevention and management of DGE remain challenging.

Perioperative risk factors for delayed gastric emptying after pancreaticoduodenectomy: a meta-analysis of the complications

Objective: To evaluate the correlation between the incidence of delayed gastric emptying (DGE) in pancreaticoduodenectomy (PD) and the perioperative possible risk factors. Methods: We searched PubMed, Embase, Cochrane Library, and Medline for studies describing complications related to PD from 2018 to 2022. Statistical analysis was performed using Stata/SE16.0 software. Results: In 6 retrospective studies, 1 systematic review, and 1 randomized controlled trial (RCT) experiment, 12,419 patients (2174 and 10,245 patients, respectively, in DGE and no delayed gastric emptying [NDGE] groups). The preoperative American Society of Anesthesiologists (ASA) score between DGE and NDGE groups (log odds ratio [OR] = 0.23, 95% credible interval [CI]: 0.11–0.35, P &lt; .01), operation time (mean diff. = 21.87, 95% CI: 15.96–27.78, P &lt; .01), estimated intraoperative blood loss (EIBL; mean diff. = 70.67, 95% CI: 17.75–123.58, P &lt; .05), postoperative pancreatic fistula (POPF) (log OR = 0.85, 95% CI: 0.24–1.46, P &lt; .05) were statistically significant. No significant differences in preoperative body mass index (BMI), preoperative biliary drainage, and pancreatic texture were observed (P &gt; .05). Conclusion: The incidence of DGE is significantly correlated with the operation time, preoperative ASA score, POPF, and EIBL,which suggests that the surgeon should thoroughly evaluate the patient through adequate preoperative examination before the operation. Finally, standardized practice and perfect technology are undoubtedly necessary to reduce complications.

Surgical Techniques of Gastrojejunostomy in Robotic Pancreatoduodenectomy: Robot-Sewn versus Stapled Gastrojejunostomy Anastomosis.

Delayed gastric emptying (DGE) is a major complication of pancreatoduodenectomy (PD). Several efforts have been made to decrease the incidence of DGE. However, the optimal anastomotic method for gastro/duodenojejunostomy (GJ) remains debatable. Moreover, few studies have reported the impact of GJ surgical techniques on outcomes following robotic pancreatoduodenectomy (RPD). This study aimed to investigate the surgical outcomes of robot-sewn and stapled GJ anastomoses in RPD. Forty patients who underwent RPD at the Okayama University Hospital between September 2020 and October 2022 were included. The outcomes between robot-sewn and stapled anastomoses were compared. The mean [standard deviation (SD)] operative and GJ time were 428 (63.5) and 34.0 (15.0) minutes, respectively. Postoperative outcomes included an overall incidence of DGE of 15.0%, and the mean postoperative hospital stays were 11.6 (5.3) days in length. The stapled group (n = 21) had significantly shorter GJ time than the robot-sewn group (n = 19) (22.7 min versus 46.5 min, p &lt; 0.001). Moreover, stapled GJ cases were significantly associated with a lower incidence of DGE (0% versus 21%, p = 0.01). Although not significant, the stapled group tended to have shorter postoperative hospital stays (9.9 days versus 13.5 days, p = 0.08). Our findings suggest that stapled GJ anastomosis might decrease anastomotic GJ time and incidence of DGE after RPD. Surgeons should select a suitable method for GJ anastomosis based on their experiences with RPD.

A new technique of duodenojejunostomy may reduce the rate of delayed gastric emptying after pylorus-preserving pancreatoduodenectomy: The growth factor technique (with video)

BackgroundDespite various technical modifications, delayed gastric emptying (DGE) is one of the most common complications after pancreatoduodenectomy. DGE results in longer hospital stay, higher cost, lower quality of life, and delay of adjuvant therapy. We have developed a modified duodenojejunostomy technique to reduce the incidence of DGE. Here we evaluate our 4-year experience with this technique. MethodsThis study evaluated consecutive patients who underwent pylorus-preserving pancreatoduodenectomy using the growth factor technique. It consists of performing a posterior seromuscular running suture with a zigzag stitch that stretches the jejunum and allows future growth of the anastomosis. This results in a longer jejunal opening. The angles at the edge of the duodenum are cut to accommodate the duodenal opening to the longer jejunum (the growth factor). The anterior seromuscular layer is then performed with interrupted sutures to accommodate the larger anastomosis. These patients were compared with a cohort of patients (n = 103) before the introduction of this new technique using propensity score matching. Results134 patients underwent pylorus-preserving pancreatoduodenectomy. Delayed gastric emptying occurred in only three patients (2.2%), one grade B and two grade C. Compared with the 103 patients in the control group with standard technique, the incidence of DGE was significantly higher (11.6%; P = 0.00318). The median hospital stay was also statistically longer in the control group (P = 0.048704). A similar trend was observed in the matched cohort; the proportion of patients who developed DGE was significantly (P = 0.005) lower in the growth factor technique group (2.1% vs. 12.9%). Hospital stay was significantly longer in the standard group (P = 0.008), and patients operated on with the standard technique resumed feeding later than those with the growth factor technique. ConclusionsThis study demonstrated that the new technique of duodenojejunostomy can reduce the incidence and severity of DGE and allow earlier hospital discharge. Comparative studies are still needed to confirm these preliminary results.

Efficacy and safety of adhesion barrier in living-donor liver transplantation with right liver graft to prevent delayed gastric emptying.

Delayed gastric emptying (DGE) is a common complication of liver transplantation. This study aimed to clarify the efficacy and safety of the application of an adhesion barrier for preventing DGE in living-donor liver transplantation. This retrospective study included 453 patients who underwent living-donor liver transplantation using a right lobe graft between January 2018 and August 2019, and the incidence of postoperative DGE and complications was compared between patients in whom adhesion barrier was used (n=179 patients) and those in whom adhesion barrier was not used (n=274 patients). We performed 1:1 propensity score matching between the 2 groups, and 179 patients were included in each group. DGE was defined according to the International Study Group for Pancreatic Surgery classification. The use of adhesion barrier was significantly associated with a lower overall incidence of postoperative DGE in liver transplantation (30.7 vs. 17.9%; p =0.002), including grades A (16.8 vs. 9.5%; p =0.03), B (7.3 vs. 3.4%; p =0.08), and C (6.6 vs. 5.5%; p =0.50). After propensity score matching, similar results were observed for the overall incidence of DGE (29.6 vs. 17.9%; p =0.009), including grades A (16.8 vs. 9.5%; p =0.04), B (6.7 vs. 3.4%; p =0.15), and C (6.1 vs. 5.0%; p =0.65). Univariate and multivariate analyses showed a significant correlation between the use of adhesion barrier and a low incidence of DGE. There were no statistically significant differences in postoperative complications between the 2 groups. The application of an adhesion barrier could be a safe and feasible method to reduce the incidence of postoperative DGE in living-donor liver transplantation.

Retrocolic gastrojejunostomy in pancreaticoduodenectomy reduces rates of delayed gastric emptying

Background: Delayed gastric emptying (DGE) is one of the most common postoperative complications in patients following pancreaticoduodenectomy (PD). This complication has been shown to effect 14-30% of patients postoperatively. Many randomized studies have shown no statistical difference between pylorus-sparing PD vs. classic PD. Additionally, the position of the anastomosis in classic PD, antecolic versus retrocolic, has also undergone randomized trials which have shown no difference in rates of DGE. The aim of this study was to report our incidence of DGE after a departmental change to a stapled retrocolic loop gastrojejunostomy as a result of high DGE with antecolic approach. The secondary aim was to identify risk factors for developing DGE on multivariate analysis.
