ABSTRACT

BACKGROUND/AIM: Although minimally invasive distal pancreatectomy (MIDP) has become a treatment option for benign and malignant pancreatic tumors, the safety and efficacy of reinforced staplers in MIDP remain controversial. The present study was performed to evaluate the safety of reinforced staplers in MIDP and identify the risk factors for postoperative pancreatic fistula (POPF) after MIDP with reinforced staplers. PATIENTS AND METHODS: In total, 92 consecutive patients who underwent MIDP at NHO Kyushu Medical Center from July 2016 to August 2023 were enrolled in this retrospective study. In all patients, a reinforced black cartridge triple-row stapler (Covidien Japan, Tokyo, Japan) was used during MIDP. The primary endpoint was the incidence of clinically relevant POPF. The risk factors for POPF were evaluated using multivariate analysis. RESULTS: Among the 92 patients, 74 underwent laparoscopic distal pancreatectomy and 18 underwent robot-assisted distal pancreatectomy. Clinically relevant POPF occurred in seven (7.6%) of 92 patients. The rate of severe complications (Clavien-Dindo grade ≥III) was 10.8%, and the mortality rate was 0%. The median postoperative hospital stay was 14 days. Multivariate logistic regression analysis showed that the independent risk factor for clinically relevant POPF after MIDP with a reinforced stapler was a body mass index of ≥22.6 kg/m2 (p=0.050, odds ratio=7.60). CONCLUSION: This study confirmed the safety and efficacy of reinforced staplers for preventing POPF after MIDP. A high body mass index was the only risk factor for clinically relevant POPF after MIDP with a reinforced stapler.

ABSTRACT

OBJECTIVE: Surgical transgastric pancreatic necrosectomy (STGN) has the potential to overcome the shortcomings (ie, repeat interventions, prolonged hospitalization) of the step-up approach for infected necrotizing pancreatitis. We aimed to determine the outcomes of STGN for infected necrotizing pancreatitis. MATERIALS AND METHODS: This observational cohort study included adult patients who underwent STGN for infected necrosis at two centers from 2008 to 2022. Patients with a procedure for pancreatic necrosis before STGN were excluded. Primary outcomes included mortality, length of hospital and intensive care unit (ICU) stay, new-onset organ failure, repeat interventions, pancreatic fistulas, readmissions, and time to episode closure. RESULTS: Forty-three patients underwent STGN at a median of 48 days (interquartile range [IQR] 32-70) after disease onset. Mortality rate was 7% (n = 3). After STGN, the median length of hospital was 8 days (IQR 6-17), 23 patients (53.5%) required ICU admission (2 days [IQR 1-7]), and new-onset organ failure occurred in 8 patients (18.6%). Three patients (7%) required a reintervention, 1 (2.3%) developed a pancreatic fistula, and 11 (25.6%) were readmitted. The median time to episode closure was 11 days (IQR 6-22). CONCLUSIONS: STGN allows for treatment of retrogastric infected necrosis in one procedure and with rapid episode resolution. With these advantages and few pancreatic fistulas, direct STGN challenges the step-up approach.

ABSTRACT

BACKGROUND: The advancement of laparoscopic technology has broadened the application of laparoscopic pancreaticoduodenectomy (LPD) for treating pancreatic head and ampullary tumors. Despite its benefits, postoperative pancreatic fistula (POPF) and postpancreatectomy hemorrhage (PPH) remain significant complications. Ligamentum teres hepatis wrapping around the gastroduodenal artery (GDA) stump show limitations in reducing POPF and PPH. METHODS: This study retrospectively analyzed patients undergoing LPD from January 2016 to October 2023, We compared the effectiveness of the two-parts wrapping (the ligamentum teres hepatis wrapping of the gastroduodenal artery stump and the omentum flap wrapping of the pancreatojejunal anastomosis) and ligamentum teres hepatis wrapping around the gastroduodenal artery (GDA) in reducing postoperative pancreatic fistula (POPF) and postpancreatectomy hemorrhage (PPH), using propensity score matching for the analysis. RESULTS: A total of 172 patients were analyzed, showing that the two-parts wrapping group significantly reduced the rates of overall and severe complications, POPF, and PPH compared to ligamentum teres hepatis wrapping around the GDA group. Specifically, the study found lower rates of grade B/C POPF and no instances of PPH in the two-parts wrapping group, alongside shorter postoperative hospital stays and drainage removal times. These benefits were particularly notable in patients with soft pancreatic textures and pancreatic duct diameters of < 3 mm. CONCLUSION: The two-parts wrapping technique significantly reduce the risks of POPF and PPH in LPD, offering a promising approach for patients with soft pancreas and pancreatic duct diameter of < 3 mm.

ABSTRACT

This systematic review and meta-analysis aimed to compare perioperative and oncologic outcomes in patients with pancreatic ductal adenocarcinoma (PDAC) treated with robotic-assisted surgery versus open laparotomy. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Randomized controlled trials (RCTs) and cohort studies up to June 15, 2024, were identified using PubMed, EMBASE, and Google Scholar. Additionally, reference lists of included studies, relevant review articles, and clinical guidelines were manually searched. The primary outcomes evaluated were length of stay, 90-day mortality, postoperative pancreatic fistula (POPF), and Post-pancreatectomy haemorrhage (PPH). Secondary outcomes included estimated blood loss, reoperation rate, lymph node yield, and operative time. The final analysis included 10 retrospective cohort studies involving 23,272 patients (2,179 robotic-assisted and 21,093 open surgery). There were no significant differences between the two procedures in terms of postoperative pancreatic fistula, Post-pancreatectomy haemorrhage, lymph node yield, and operative time. However, patients undergoing robotic-assisted surgery had shorter lengths of stay, lower 90-day mortality, and less estimated blood loss compared to those undergoing open surgery. The reoperation rate was higher for the robotic-assisted group. Robotic-assisted surgery for pancreatic ductal adenocarcinoma is safe and feasible. Compared to open surgery, it offers better perioperative and short-term oncologic outcomes, but with a higher risk of reoperation.

ABSTRACT

PURPOSE: We retrospectively analyzed pancreatectomy patients and examined the occurrence rate and timing of postoperative complications (time-to-complication; TTC) and their impact on the length of postoperative hospital stay (POHS) to clarify their characteristics, provide appropriate postoperative management, and improve short-term outcomes in the future. METHODS: A total of 227 patients, composed of 118 pancreaticoduodenectomy (PD) and 109 distal pancreatectomy (DP) cases, were analyzed. We examined the frequency of occurrence, TTC, and POHS of each type of postoperative complication, and these were analyzed for each surgical procedure. Complications of the Clavien-Dindo (CD) classification Grade II or higher were considered clinically significant. RESULTS: Clinically significant complications were observed in 70.3% and 36.7% of the patients with PD and DP, respectively. Complications occurred at a median of 10 days in patients with PD and 6 days in patients with DP. Postoperative pancreatic fistula (POPF) occurred approximately 7 days postoperatively in both groups. For the POHS, in cases without significant postoperative complications (CD ≤ I), it was approximately 22 days for PD and 11 days for DP. In contrast, when any complications occurred, POHS increased to 30 days for PD and 19 days for DP (each with additional 8 days), respectively. In particular, POPF prolonged the hospital stay by approximately 11 days for both procedures. CONCLUSION: Each postoperative complication after pancreatectomy has its own characteristics in terms of the frequency of occurrence, TTC, and impact on POHS. A correct understanding of these factors will enable timely therapeutic intervention and improve short-term outcomes after pancreatectomy.

ABSTRACT

AIM: The aim of our study was to investigate the clinical results of omental flap application during pancreaticojejunostomy (PJ) anastomosis in pancreatoduodenectomy (PD) surgeries. METHODS: The data of patients who underwent pancreaticoduodenectomy in our hospital were evaluated retrospectively. The patients were divided into two groups; patients with an omental flap (Group 1) and those without an omental flap (Group 2). The demographic and other characteristics of the groups and the incidence of postoperative pancreatic fistula (POPF) development were compared. RESULTS: One hundred patients were included (39 females, 61 males) Group 1 consisted of 20 patients with omental flaps and Group 2 consisted of 80 patients without omental flaps. While no clinically significant (Grade B and C) leaks were observed in Group 1, both biochemical and clinically significant leak rates were lower in Group 1 compared to 4 patients (5%) in Group 2. There was no statistically significant difference compared with Group 2 (p > 0.05). CONCLUSIONS: Although not statistically significant in this study, postoperative complication rates and the incidence of POPF tended to decrease in patients who underwent omental flaps.

ABSTRACT

BACKGROUND: Clinically relevant postoperative pancreatic fistula (CR-POPF) is a significant complication after pancreaticoduodenectomy. CR-POPF is associated with various adverse outcomes, including high mortality rates. Identifying complication predictors for CR-POPF, such as preoperative CT scan features, including pancreatic attenuation index (PAI) and pancreatic duct diameter (PDD), is critical. This systematic review and meta-analysis consolidate existing literature to assess the impact of these variables on CR-POPF risk. METHODS: Our comprehensive search, conducted in May 2023, covered PubMed, Scopus, Embase, and Web of Science databases. Inclusion criteria encompassed peer-reviewed cohort studies on pancreaticoduodenectomy, focusing on preoperative CT scan data. Case reports, case series, and studies reporting distal pancreatectomy were excluded. The quality assessment of included articles was done using New-Castle Ottawa Scale for cohort studies. Statistical analysis was carried out using Review Manager 5. This study was registered at the International Prospective Register of Systematic Reviews database (PROSPERO) on 12 May 2023 (registration number: CRD42023414139). RESULTS: We conducted a detailed analysis of 38 studies with 7393 participants. The overall incidence of CR-POPF was 24%. Multiple linear regression analyses revealed that PDD and pancreatic parenchymal thickness were significantly associated with CR-POPF. CONCLUSION: Our systematic review and meta-analysis shed light on CT scan findings for predicting CR-POPF after Whipple surgery. Age, PDD, and pancreatic parenchymal thickness significantly correlate with CR-POPF.

ABSTRACT

PURPOSE: Post-operative pancreatic fistula (POPF) remains the main complication after distal pancreatectomy (DP). The aim of this study is to evaluate the potential benefit of different durations of progressive stapler closure on POPF rate and severity after DP. METHODS: Patients who underwent DP between 2016 and 2023 were retrospectively enrolled and divided into two groups according to the duration of the stapler closure: those who underwent a progressive compression for < 10 min and those for ≥ 10 min. RESULTS: Among 155 DPs, 83 (53.5%) patients underwent pre-firing compression for < 10 min and 72 (46.5%) for ≥ 10 min. As a whole, 101 (65.1%) developed POPF. A lower incidence rate was found in case of ≥ 10 min compression (34-47.2%) compared to < 10 min compression (67- 80.7%) (p = 0.001). When only clinically relevant (CR) POPFs were considered, a prolonged pre-firing compression led to a lower rate (15-20.8%) than the < 10 min cohort (32-38.6%; p = 0.02). At the multivariate analysis, a compression time of at least 10 min was confirmed as a protective factor for both POPF (OR: 5.47, 95% CI: 2.16-13.87; p = 0.04) and CR-POPF (OR: 2.5, 95% CI: 1.19-5.45; p = 0.04) development. In case of a thick pancreatic gland, a prolonged pancreatic compression for at least 10 min was significantly associated to a lower rate of CR-POPF compared to < 10 min (p = 0.04). CONCLUSION: A prolonged pre-firing pancreatic compression for at least 10 min seems to significantly reduce the risk of CR-POPF development. Moreover, significant advantages are documented in case of a thick pancreatic gland.

ABSTRACT

Bevezetés: A posztoperatív pancreasfistula mind proximalis, mind distalis pancreatectomia után a legjelentosebb sebészi szövodménynek számít. A szakirodalomban nincs egyértelmuen ajánlott, megbízható módszer ezen probléma kiküszöbölésére, emiatt történnek újítások szerte a világon. Jelen közleményünkben a technikai innovációinkról számolunk be. Anyag és módszerek: 2013. január 1-jétol 2023. november 30-ig terjedo idoszakban 205 Whipple-mutétet végeztünk nyitottan, mely során a pancreatojejunalis anastomosist az általunk módosított dohányzacskó-öltéses módszerrel készítettük el. 2019. január 1. és 2023. november 30. között pedig 30 betegnél történt nyitott distalis pancreatectomia, amikor a pancreascsonkot az általunk kifejlesztett technikával, szabad rectus fascia-peritoneum grafttal fedtük, majd azt cirkuláris öltéssel rögzítettük. Közleményünkben ezen két módszerrel elért eredményeket ismertetjük. Eredmények: a demográfiai adatok megfeleltek a betegségnél szokásosnak. A posztoperatív ápolási ido és a transzfúzió igény terén észlelt különbségek tükrözték a kétféle beavatkozás eltéro invazivitását. A releváns pancreasfistula kialakulási rátája kedvezo képet mutatott, Whipple-mutét után 7,3% volt, míg distalis pancreatectomát követoen nem fejlodött ki. A reoperációs és a halálozási arányok megfeleltek az elvártaknak és korreláltak a mutétek kiterjedtségével. Következtetés: pancreas resectiók utáni komplikációk csökkentésére tett törekvéseink során a módosított dohányzacskó-öltéses pancreatojejunostomia és a pancreascsonk fedésére kidolgozott módszerünk egyaránt kedvezo eredményekkel járt.

ABSTRACT

BACKGROUND: Postoperative pancreatic fistula (POPF) is one of the most feared and common complications following pancreatoduodenectomies. This study aims to evaluate the performance of different scales in predicting POPF using magnetic resonance imaging (MRI), including estimation of the pancreatic duct diameter, pancreatic texture, main duct index, relation to the portal vein, and intra-abdominal fat thickness. MATERIALS AND METHODS: A retrospective diagnostic test study was designed. Between January 2017 and December 2021, 133 pancreatoduodenectomies were performed at our institution. The performance for predicting overall POPF and clinically relevant POPF (CR-POPF) was evaluated using a receiver operating characteristic (ROC) curve. RESULTS: A total of 96 patients were included in the study, of whom 26 patients experienced overall POPF, and 8 patients had CR-POPF. When analyzing the predictive value of each of the different scores applied, the Birmingham score showed the highest performance for predicting overall POPF and CR-POPF with an AUC (area under the curve) of 0.815 (95 % CI 0.725-0.906) and 0.813 (0.679-0.947), respectively. CONCLUSION: The Birmingham scale demonstrated the highest predictive performance for POPF. It is a simple scale with only two variables that can be obtained preoperatively using MRI. Based on these results, we recommend its use in patients undergoing pancreatoduodenectomy.

ABSTRACT

BACKGROUND: No single technique of remnant pancreas reconstruction after pancreaticoduodenectomy (PD) has been demonstrated to be superior to the others in the prevention of post-operative pancreatic fistula (POPF), and the accumulation of surgical experience is closely related to the quality of this anastomosis. The aim of the current study was to evaluate the feasibility and patient outcomes of a simplified technique involving a single-layer continuous pancreaticojejunostomy (PJA) with Falciform ligament reinforcement that can be used with all types of pancreases. METHODS: A single-centre and single-surgeon study was performed. One hundred consecutive patients undergoing pancreatic resection with subsequent PJA using a novel technique performed by a single surgeon were included in the study. Patient demographics, pre-operative treatments, risk factors for POPF, and post-operative morbidity and mortality and long-term patient outcome were prospectively recorded and reported. RESULTS: From March 2018 to March 2022, 59 male and 41 female patients were included. 91 patients underwent PD for malignancy with 32 receiving neoadjuvant treatment. 59 patients were classified as intermediate/high risk for POPF according to validated fistula prediction models. There were 12 POPF Type B and 2 POPF Type C. The overall morbidity rate was 16% with no 90-day mortality. 3 patients underwent reoperation. The median length of hospitalisation was 12.6 days and 82% of eligible patients commenced and completed adjuvant chemotherapy. CONCLUSION: Single-layer continuous dunking PJA with Falciform ligament reinforcement is a simplified and feasible method for PJA with a low associated complication rate.

ABSTRACT

BACKGROUND: Pancreatic fistula (PF) is one of the most serious postoperative complications of gastrectomy. Misidentification of the boundary between the pancreas and the dissected fat is a primary concern. In this study, we focused on differences in the appearance of the pancreas and the dissected fat in actual surgical images and statistically analyzed the relationship between the pancreas and the dissected fat. METHODS: We analyzed data from 109 gastric cancer patients who underwent curative gastrectomy between November 2018 and March 2023. Intraoperative images were taken from videos of lymph node dissections of Nos.6 and 8a regions, and the mean gray value of the areas was measured using ImageJ software for analysis. The visceral fat area (VFA) was evaluated by preoperative axial CT at the umbilical level using Ziostation software. RESULTS: A significant correlation was observed between the fat/pancreas gray value ratio in the No.8a lymph node region and the drain/serum amylase ratio (P < 0.001). The fat/pancreas gray value ratio in the No.6 lymph node region correlated with VFA (P < 0.001). The VFA and drain/serum amylase ratio were significantly higher in the group with intra-abdominal complications (P = 0.004). CONCLUSIONS: We revealed significant relationships between the fat/pancreas gray value ratio with drain/serum amylase and VFA. Detecting differences in gray values between the pancreas and the dissected fat may lead to a decrease in the drain/serum amylase ratio and PF.

ABSTRACT

BACKGROUND: Postoperative pancreatic fistulas remain a driver of major complications after partial pancreatectomy. It is unclear whether coverage of the anastomosis or pancreatic remnant can reduce the incidence of postoperative pancreatic fistulas. The aim of this study was to evaluate the effect of autologous or artificial coverage of the pancreatic remnant or anastomosis on outcomes after partial pancreatectomy. METHODS: A systematic literature search was performed using MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL) up to March 2024. All RCTs analysing a coverage method in patients undergoing partial pancreatoduodenectomy or distal pancreatectomy were included. The primary outcome was postoperative pancreatic fistula development. Subgroup analyses for pancreatoduodenectomy or distal pancreatectomy and artificial or autologous coverage were conducted. RESULTS: A total of 18 RCTs with 2326 patients were included. In the overall analysis, coverage decreased the incidence of postoperative pancreatic fistulas by 29% (OR 0.71, 95% c.i. 0.54 to 0.93, P < 0.01). This decrease was also seen in the 12 RCTs covering the remnant after distal pancreatectomy (OR 0.69, 95% c.i. 0.51 to 0.94, P < 0.02) and the 4 RCTs applying autologous coverage after pancreatoduodenectomy and distal pancreatectomy (OR 0.53, 95% c.i. 0.29 to 0.96, P < 0.04). Other subgroup analyses (artificial coverage or pancreatoduodenectomy) showed no statistically significant differences. The secondary endpoints of mortality, reoperations, and re-interventions were each affected positively by the use of coverage techniques. The certainty of evidence was very low to moderate. CONCLUSION: The implementation of coverage, whether artificial or autologous, is beneficial after partial pancreatectomy, especially in patients undergoing distal pancreatectomy with autologous coverage.

ABSTRACT

BACKGROUND: Postoperative pancreatic fistulas (POPFs) occur after 20% to 30% of laparoscopic distal pancreatectomies. This study aimed to evaluate the clinical efficacy of laparoscopic distal pancreatectomy using triple-row staplers in preventing POPFs. METHODS: Between April 2016 and May 2023, 59 patients underwent complete laparoscopic distal pancreatectomies. There were more females (n=34, 57.6%) than males (n=25, 42.4%). The median age of the patients was 68.9 years. The patients were divided into slow-compression (n=19) and no-compression (n=40) groups and examined for pancreatic leakage. Both groups were examined with respect to age, sex, body mass index (BMI), pancreatic thickness at the pancreatic dissection site, pancreatic texture, diagnosis, operative time, blood loss, presence of POPF, date of drain removal, and length of hospital stay. In addition, risk factors for POPF were examined in a multivariate analysis. RESULTS: Grade B POPFs were found in 9 patients (15.3%). Using univariate analysis, the operative time, blood loss, postoperative pancreatic fluid leakage, day of drain removal, and hospital stay were shorter in the no-compression group than in the slow-compression group. Using multivariate analysis, the absence of POPFs was significantly more frequent in the no-compression group (odds ratio, 5.69; 95% CI, 1.241-26.109; P =0.025). The no-compression pancreatic dissection method was a simple method for reducing POPF incidence. CONCLUSIONS: The method of quickly dissecting the pancreas without compression yielded better results than the method of slowly dissecting the pancreas with slow compression. This quick dissection without compression was a simple and safe method that minimized postoperative pancreatic fluid leakage, shortened the operative time and length of hospital stay, and reduced medical costs. Therefore, this method might be a clinically successful option.

ABSTRACT

BACKGROUND: Clinically relevant postpancreatectomy hemorrhage occurs in 10% to 15% of patients after pancreaticoduodenectomy, mainly in association with clinically relevant postoperative pancreatic fistula. Prevention of postpancreatectomy hemorrhage by arterial coverage with a round ligament plasty or an omental flap is controversial. This study assessed the impact of arterial coverage with an original retromesenteric omental flap on postpancreatectomy hemorrhage after pancreaticoduodenectomy. METHODS: This single-center retrospective study included 812 open pancreaticoduodenectomies (2012-2021) and compared 146 procedures with arterial coverage using retromesenteric omental flap to 666 pancreaticoduodenectomies without arterial coverage. The Fistula Risk Score was calculated. The primary endpoint was a 90-day clinically relevant postpancreatectomy hemorrhage rate according to the International Study Group of Pancreatic Surgery classification. RESULTS: There were more patients with a Fistula Risk Score ≥7 in the arterial coverage-retromesenteric omental flap group: 18 (12%) versus 48 (7%) (P < .01). Clinically relevant postpancreatectomy hemorrhage was less frequent in the arterial coverage- retromesenteric omental flap group than in the no arterial coverage group: 5 (3%) versus 66 (10%), respectively (P = .01). Clinically relevant postoperative pancreatic fistula occurred in 28 (19%) patients in the arterial coverage- retromesenteric omental flap group compared with 165 (25%) in the no arterial coverage group (P = .001). There were fewer reoperations for postpancreatectomy hemorrhage or postoperative pancreatic fistula in the arterial coverage- retromesenteric omental flap group: 1 (0.7%) versus 32 (5%) in the no arterial coverage group (P = .023). In multivariate analysis, arterial coverage with retromesenteric omental flap was an independent protective factor of clinically relevant postpancreatectomy hemorrhage (odds ratio 0.33; 95% confidence interval [0.12-0.92], P = .034) whereas postoperative pancreatic fistula of any grade (odds ratio = 10.1; 95% confidence interval: 5.1-20.3, P < .001) was predictive of this complication. CONCLUSION: Arterial coverage with retromesenteric omental flap can reduce rates of clinically relevant postpancreatectomy hemorrhage after pancreaticoduodenectomy. This easy and costless technique should be prospectively evaluated to confirm these results.

ABSTRACT

BACKGROUND: The method of transecting the pancreatic parenchyma during pancreatic resection may influence the rate of complications, including pancreatic fistula and bleeding. The objective of this study was to compare the transection of the pancreatic parenchyma during pancreatoduodenectomy with monopolar electrocautery versus scalpel in terms of postoperative complications. METHODS: A retrospective analysis of patients with open pancreatoduodenectomy from the German DGAV StuDoQ|Pancreas registry (January 2013 to December 2021) was performed. Transection of the pancreatic parenchyma with a scalpel versus monopolar electrocautery was compared regarding postoperative pancreatic fistula B/C, post-pancreatectomy hemorrhage B/C, and major complications (Clavien-Dindo classification ≥3) rates. Multivariable analysis with adjustment for potential confounders and surgical center cluster effect was performed. RESULTS: Overall, 6,752 patients were included in the study. In 4,072 (60.3%), transection was performed with a scalpel and, in 2,680 (39.7%), with electrocautery. Transection with electrocautery was associated with higher postoperative pancreatic fistula B/C (15.4% vs 12.8%; P = .003), post-pancreatectomy hemorrhage B/C (11% vs 7.4%; P < .001), and major complications (33.4% vs 29.6%; P = .001) rates. In the multivariable analysis, after adjustment for potential confounders and surgical center, the association of the transection method with postoperative pancreatic fistula B/C (odds ratio = 1.01; 95% CI, 0.79-1.2; P = .962), post-pancreatectomy hemorrhage B/C (odds ratio = 1.23; 95% CI, 0.94-1.6; P = .127), and major complications (odds ratio = 1.09; 95% CI, 0.93-1.27; P = .297) was not significant. CONCLUSION: The study found no significant association between transection of the pancreatic parenchyma during open pancreatoduodenectomy with a scalpel compared with monopolar electrocautery regarding pancreatic fistula, postoperative bleeding, or overall major complication rates.
