ABSTRACT
Heterotopic pancreas is a rare congenital abnormality. The most common location is the stomach, duodenum and proximal jejunum. Rare locations are represented by the ampulla of Vater, esophagus, ileum, Meckel diverticulum, biliary tract, mesentery and spleen. We present the case of a 49 year old patient investigated for obstructive jaundice and diagnosed with an ampullar heterotopy of pancreas parenchyma, initially considered to be a malignant tumor. A Whipple pancreatoduodenectomy was performed with good postoperative evolution, the serum levels of bilirubin being normal after the first postoperative week.

Robotic surgery has been increasingly adopted in various surgical fields, but the cost-effectiveness of this technology remains controversial due to its high cost and limited improvements in clinical outcomes. This study aims to explore the health economic implications of robotic pancreatic surgery, to investigate its impact on hospitalization costs and consumption of various medical resources. Data of patients who underwent pancreatic surgery at our institution were collected and divided into robotic and traditional groups. Statistical analyses of hospitalization costs, length of stay, costs across different service categories, and subgroup cost analyses based on age, BMI class, and procedure received were performed using t tests and linear regression. Although the total hospitalization cost for the robotic group was significantly higher than that for the traditional group, there was a notable reduction in the cost of medical consumables. The reduction was more prominent among elderly patients, obese patients, and those undergoing pancreaticoduodenectomy, which could be attributed to the technological advantages of the robotic surgery platform that largely facilitate blood control, tissue protection, and suturing. The study concluded that despite higher overall costs, robotic pancreatic surgery offers significant savings in medical consumables, particularly benefiting certain patient subgroups. The findings provide valuable insights into the economic viability of robotic surgery, supporting its adoption from a health economics perspective.

Postpancreatectomy hemorrhage (PPH) is an important risk factor for postoperative complications after laparoscopic pancreaticoduodenectomy (LPD). Recent studies have reported that the use of ligamentum teres hepatis (LTH) in LPD may reduce the risk of PPH. Therefore, this study aims to investigate whether wrapping the hepatic hilar artery with the LTH can reduce PPH after LPD. We reviewed the data of 131 patients who underwent LPD in our team from April 2018 to December 2023. The patients were divided into Groups A (60 patients) and B (71 patients) according to whether the hepatic portal artery was wrapped or not. The perioperative data of the two groups were compared to evaluate the effect of LTH wrapping the hepatic hilar artery on LPD. The platelet count of Group A was (225.25 ± 87.61) × 10^9/L, and that of Group B was (289.38 ± 127.35) × 10^9/L, with a statistically significant difference (p < 0.001). The operation time of group A [300.00 (270.00, 364.00)] minutes was shorter than that of group B [330.00 (300.00, 360.00)] minutes, p = 0.037. In addition, A set of postoperative hospital stay [12.00 (10.00, 15.00)] days shorter than group B [15.00 (12.00, 19.50)] days, p < 0.001. No PPH occurred in Group A, while 8 patients in Group B had PPH (7 cases of gastroduodenal artery hemorrhage and 1 case of proper hepatic artery hemorrhage), p = 0.019. The new technique of wrapping the hepatic hilar artery through the LTH can effectively reduce the occurrence of PPH after LPD.

PURPOSE: To reduce perioperative risks among patients with a preoperative diabetes mellitus (DM) a total pancreatectomy (TP) might be a alternative to pancreatoduodenectomy (PD). This study aimed to compare the postoperative quality of life (QoL) of patients with preoperative DM undergoing PD or TP. METHODS: A single-centre retrospective study was conducted, all consecutive patients with preoperative DM undergoing PD or TP between 2011 and 2023 were identified in a prospective database. The primary endpoint was QoL, prospectively assessed using EORTC QLQ-C30 questionnaires at 3, 6, and 12 months after surgery and then annually until death. Secondary endpoints were morbidity and mortality. RESULTS: Seventy-one patients were included, 17 after TP and 54 after PD. Insulin-dependent DM occurred in 21 (39%) of the PD patients. QoL was worse after TP, especially in terms of physical functioning (-31.7 points; 95% CI: -50.0 to -13.3; P < 0.001), role functioning (-41.3 points; 95% CI: -61.3 to -21.3; P < 0.001), emotional functioning (-27.5 points; 95% CI: -50.4 to -4.6; P = 0.019), fatigue symptoms (20 points; 95% CI: 2.7 to 37.4; P = 0.024) and pain symptoms (30.2 points; 95% CI: 4.1 to 56.3; P = 0.024). The rates of postoperative major complications (29% vs. 35%; P = 0.853) and mortality (11% vs. 7%; P = 0.857) were similar between TP and PD. CONCLUSION: Postoperative morbidity and mortality were comparable between PD and TP, however QoL is significantly lower after TP. Importantly, patients with preoperative DM have a 60% chance of remaining noninsulin-dependent after PD.

OBJECTIVE: Achieving textbook outcome (TO) implies a smooth recovery post-operation without specified composite complications. This study aimed to evaluate TO in laparoscopic pancreaticoduodenectomy (LPD) and identify independent risk factors associated with achieving TO. METHODS: We conducted a retrospective analysis of data from a randomized controlled trial on LPD at West China Hospital (ChiCTR1900026653). Patients were categorized into the TO and non-TO groups. Perioperative variables were compared between these groups. Multivariate logistic regression was utilized to identify the risk factors. RESULTS: A total of 200 consecutive patients undergoing LPD were included in this study. TO was achieved in 82.5% (n = 165) of the patients. Female patients (OR: 2.877, 95% CI: 1.219-6.790; P = 0.016) and those with a hard pancreatic texture (OR: 2.435, 95% CI: 1.018-5.827; P = 0.046) were associated with an increased likelihood of achieving TO. CONCLUSIONS: TO can be achieved in more than 80% of patients in a high-volume LPD center. Independent risk factors associated with achieving TO included gender (male) and pancreatic texture (soft).

With the development of robotic systems, robotic pancreatoduodenectomies (RPDs) have been increasingly performed. However, the number of cases required by surgeons with extensive laparoscopic pancreatoduodenectomy (LPD) experience to overcome the learning curve of RPD remains unclear. Therefore, we aimed to analyze and explore the impact of different phases of the learning curve of RPD on perioperative outcomes. Clinical data were prospectively collected and retrospectively analyzed for 100 consecutive patients who underwent RPD performed by a single surgeon. This surgeon had previous experience with LPD, having performed 127 LPDs with low morbidity. The learning curve for RPD was analyzed using the cumulative sum (CUSUM) method based on operation time, and perioperative outcomes were compared between the learning and proficiency phases. Between April 2020 and November 2022, one hundred patients (56 men, 44 women) were included in this study. Based on the CUSUM curve of operation time, the learning curve for RPD was divided into two phases: phase I was the learning phase (cases 1-33) and phase II was the proficiency phase (cases 34-100). The operation time during the proficiency phase was significantly shorter than that during the learning phase. In the learning phase of RPD, no significant increases were observed in estimated blood loss, conversion to laparotomy, severe complications, postoperative pancreatic hemorrhage, clinical pancreatic fistula, or other perioperative complications compared to the proficiency phases of either RPD or LPD. A surgeon with extensive prior experience in LPD can safely surmount the RPD learning curve without increasing morbidity in the learning phase. The proficiency was significantly improved after accumulating experience of 33 RPD cases.

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.

INTRODUCTION: The prevalence of overweight or obesity among patients undergoing pancreaticoduodenectomy is on the rise. The utilisation of robotic assistance has the potential to enhance the feasibility of performing minimally invasive pancreaticoduodenectomy in this particular group of patients who are at a higher risk. The objective of this meta-analysis is to assess the safety and effectiveness of robotic pancreaticoduodenectomy in individuals with overweight or obesity. METHODS AND ANALYSIS: This investigation will systematically search for randomised controlled trials (RCTs) and non-randomised comparative studies that compare robotic pancreaticoduodenectomy with open or laparoscopic pancreaticoduodenectomy in patients with overweight or obesity, using PubMed, Embase and the Cochrane Library databases. The methodological quality of studies will be evaluated using the Cochrane risk of bias tool for RCTs and the Newcastle-Ottawa Scale for observational studies. RevMan software (V.5.4.1) will be used for statistical analysis. The OR and weighted mean differences will be calculated separately for dichotomous and continuous data. The selection of a fixed-effects or random-effects model will depend on the level of heterogeneity observed among the included studies. ETHICS AND DISSEMINATION: This study will be conducted based on data in the published literature from publicly available databases. Therefore, ethics approval is not applicable. The results will be disseminated in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023462321.

BACKGROUND: The appropriate surgical approach for pancreatic ductal adenocarcinoma (PDAC) is determined by the tumor's relation to the porto-mesenteric axis. Although the extent and location of lymphadenectomy is dependent on the type of resection, a pancreatoduodenectomy (PD), distal pancreatectomy (DP), or total pancreatectomy (TP) are considered equivalent oncologic operations for pancreatic neck tumors. Therefore, we aimed to assess differences in histopathological and oncological outcomes for surgical approaches in the treatment of pancreatic neck tumors. METHODS: Patients with resected PDAC located in the pancreatic neck were identified from the National Cancer Database (2004-2020). Patients with metastatic disease were excluded. Furthermore, patients with 90-day mortality and R2-resections were excluded from the multivariable Cox-regression analysis. RESULTS: Among 846 patients, 58% underwent PD, 25% DP, and 17% TP with similar R0-resection rates (p = 0.722). Significant differences were observed in nodal positivity (PD:44%, DP:34%, TP:57%, p < 0.001) and mean-number of examined lymph nodes (PD:17.2 ± 10.4, DP:14.7 ± 10.5, TP:21.2 ± 11.0, p < 0.001). Furthermore, inadequate lymphadenectomy (< 12 nodes) was observed in 30%, 44%, and 19% of patients undergoing PD, DP, and TP, respectively (p < 0.001). Multivariable analysis yielded similar overall survival after DP (HR:0.83, 95%CI:0.63-1.11), while TP was associated with worse survival (HR:1.43, 95%CI:1.08-1.89) compared to PD. CONCLUSION: While R0-rates are similar amongst all approaches, DP is associated with inadequate lymphadenectomy which may result in understaging disease. However, this had no negative influence on survival. In the premise that an oncological resection of the pancreatic neck tumor is feasible with a partial pancreatectomy, no benefit is observed by performing a TP.

INTRODUCTION: Studies comparing laparoscopic pancreaticoduodenectomy (LPD) with open pancreaticoduodenectomy (OPD) for ampullary carcinoma (AC) are limited. This study aimed to compare short- and long-term outcomes between LPD and OPD for AC. METHODS: This study included patients with AC who underwent pancreaticoduodenectomy (PD) with curative intention at Ogaki Municipal Hospital from April 2008 to March 2023. RESULTS: Fifty-five patients underwent LPD (n = 26) or OPD (n = 29). There were no significant differences in the demographics between the two groups. The LPD group had a significantly longer operative time (268 vs. 225 min), less blood loss (125 vs. 450 mL), and shorter postoperative hospital stay (18 vs. 23 days) than the OPD group. There was no significant difference in the morbidity ratio. Fewer lymph nodes were harvested in the LPD group than OPD group (9.5 vs. 16.0), but there were no significant differences in lymph node metastasis or pathological stages. There were no significant differences in overall survival (OS) or recurrence-free survival (RFS). The 3- and 5-year OS rates in the LPD group and the OPD group were 63.0% and 54%, 64.8%, and 61.2%, respectively. The 3- and 5-year RFS rates were 57.4% and 57.4%, 58.1%, and 54.4%, respectively. CONCLUSIONS: LPD for AC had short- and long-term outcomes comparable with those of OPD. LPD could be considered the standard treatments for AC because of less blood loss and a shorter hospital stay.

In its 20th anniversary, laparoscopic pancreatoduodenectomy, while feasible and safe in the hands of experienced surgeons, has not seen the anticipated popularity observed in other digestive surgery procedures. The primary hurdle remains the absence of a clear advantage over traditional open surgery, paired with the procedures complexity and a consequent steep learning curve. In regions with limited pancreatic surgery services, conducting this procedure without adequate training can have serious repercussions. Given the advent of robotic platforms and the anticipation of prospective and randomized studies on this new technology, it is imperative to engage in comprehensive discussions, endorsed by surgical societies, on the value, application, and implementation strategies for various minimally invasive pancreatoduodenectomy techniques. Such dialogue is crucial for advancing the field and ensuring optimal patient outcomes.

The role and risks of pre-operative endoscopic procedures, such as endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound with fine needle aspiration (EUS/FNA), in patients undergoing robotic pancreaticoduodenectomy are not well-defined despite a broad consensus on the utility of these interventions for diagnostic and therapeutic purposes prior to major pancreatic operations. This study investigates the impact of such preoperative endoscopic interventions on perioperative outcomes in robotic pancreaticoduodenectomy. With Institutional Review Board (IRB) approval we retrospectively analyzed 772 patients who underwent robotic pancreatectomies between 2012 and 2023. Specifically, 430 of these patients underwent a robotic pancreaticoduodenectomy were prospectively evaluated: 93 (22%) patients underwent ERCP with EUS and FNA, 45 (10%) ERCP only, and 31 (7%) EUS and FNA, while 261 (61%) did not. Statistical analyses were performed using chi-square tests and Student's t-tests to compare perioperative outcomes between the two cohorts. Statistically significant differences were observed in patients who underwent a pre-operative endoscopic intervention and were more likely to have converted to an open operation (p = 0.04). The average number of harvested lymph nodes for patients who underwent preoperative endoscopic intervention was statistically significant compared to those who did not (p = 0.0001). All other perioperative variables were consistent across all cohorts. Patients who underwent endoscopic intervention before robotic pancreaticoduodenectomy were more likely to have an unplanned open operation. This study demonstrates the increased operative difficulties introduced by preoperative endoscopic interventions. Although there was no impact on overall patient outcomes, surgeons' experience can minimize the associated risks.

OBJECTIVE: This study aimed to compare the postoperative outcomes of < 75-year-old patients and ≥ 75-year-old patients who underwent pancreaticoduodenectomy (PD) for pancreatic head and periampullary region tumors. METHODS: Patients who underwent PD in our hospital between February 2019 and December 2023 were evaluated. Demographics, Eastern Cooperative Oncology Group Performance Status (ECOG-PS) scores, American Society of Anesthesiologists (ASA) scores, comorbidities, hospital stays, complications, and clinicopathological features were analyzed. Patients were divided into < 75 years (Group A) and ≥ 75 years (Group B) groups and compared. RESULTS: The median age of the entire cohort (n = 155) was 66 years (IQR = 16). There was a significant difference between Group A (n = 128) and Group B (n = 27) regarding the ECOG-PS and ASA scores. There was no significant difference between the groups regarding postoperative complications. The 30-day mortality rate was greater in Group B (p = 0.017). Group B had a cumulative median survival of 10 months, whereas Group A had a median survival of 28 months, with a statistically significant difference (p < 0.001). When age groups were stratified according to ECOG-PS, for ECOG-PS 2-3 Group A, survival was 15 months; for ECOG-PS 2-3 Group B, survival was eight months, and the difference was not statistically significant (p = 0.628). CONCLUSIONS: With the increasing aging population, patient selection for PD should not be based solely on age. This study demonstrated that PD is safe for patients older than 75 years. In older patients, performance status and the optimization of comorbidities should be considered when deciding on a candidate's suitability for surgery.

OBJECTIVE: The mini-fluid challenge (MFC), which assesses the change in stroke volume index (SVI) following the administration of 100 mL of crystalloids, and the short-time low positive end-expiratory pressure (PEEP) challenge (SLPC), which evaluates the temporary reduction in SVI due to a PEEP increment, are two functional hemodynamic tests used to predict fluid responsiveness in the operating room. However, SLPC has not been assessed in patients undergoing abdominal surgery, and there is no study comparing these two methods during laparotomy. Therefore, we aimed to compare the SLPC and MFC in patients undergoing open pancreaticoduodenectomy. PATIENTS AND METHODS: All patients received a standard hemodynamic management. The study protocol evaluated the percentage change in SVI following the application of an additional 5 cmH2O PEEP (SVIΔ%-SLPC) and the infusion of 100 mL crystalloid (SVIΔ%-MFC). Challenges that resulted in an increase of more than 15% in SVI after the 500 ml of fluid loading were classified as positive challenges (PC). Areas under the receiver operating characteristics curves (ROC AUCs) were used for the comparison of the methods. RESULTS: Thirty-three patients completed the study with 94 challenges. Fifty-five (58.5%) of them were PCs. The ROC AUC of SVIΔ%-MFC was observed to be significantly higher than that of SVIΔ%-SLPC (0.97 vs. 0.64, p < 0.001). The best cut-off value for SVIΔ%-MFC was 5.6%. If we had stopped the bolus fluid administration when SVIΔ%-MFC ≤ 5% was observed (lower limit of the gray zone), we would have postponed the fluid loading in 35 (89.7%) of 39 negative challenges. The amount of fluid deferred would have corresponded to up to 40% of the total fluid given. CONCLUSIONS: SVIΔ%-MFC predicts fluid responsiveness with high diagnostic performance and is better than SVIΔ%-SLPC in patients undergoing open pancreatoduodenectomy. Additionally, the use of SVIΔ%-MFC has the potential to defer up to 40% of the total fluid given. CLINICALTRIALS: gov: NCT05419570.

INTRODUCTION: High-grade pancreaticoduodenal injuries are highly morbid and may require complex surgical management. Pancreaticoduodenectomy (Whipple procedure) is sometimes utilized in the management of these injuries, but guidelines on its use are lacking. This paper aims to present our 14-year experience in management of high-grade pancreaticoduodenal injuries at our busy, urban trauma center. METHODS: A retrospective review was performed on patients (ages >15 years) presenting with high-grade (AAST-OIS Grades IV and V) injuries to the pancreas or duodenum at our Southeastern Level 1 trauma center. Inclusion criteria included high-grade injury and requirement of Whipple procedure based on surgeon discretion. Patients were divided into two groups: (1) those who underwent Whipple procedures during the index operation and (2) Whipple candidates. Whipple candidates included patients who received Whipples in a staged fashion or who would have benefited from the procedure but either died or were salvaged to another procedure. Demographics, injury patterns, management, and outcomes were compared. Primary outcome was survival to discharge. RESULTS: Of 66,272 trauma patients in this study period, 666 had pancreatic or duodenal injuries, and 20 met inclusion criteria. Of these, 6 had Whipples on the index procedure and 14 were Whipple candidates (among whom 7 had staged Whipples, 6 died before completing a Whipple, and 1 was salvaged). Median (IQR) age was 28 (22.75-40) years. Patients were 85 % male, 70 % Black. GSWs comprised 95 % of injuries. All patients had at least one concomitant injury, most commonly major vascular injury (75 %), colonic injury (65 %), and hepatic injury (60 %). In-hospital mortality among Whipple patients was 15 %. CONCLUSIONS: Complex pancreaticoduodenal injuries requiring pancreaticoduodenectomy are rare but life-threatening. In such patients, hemorrhage was the leading cause of death in the first 24 h. Approximately half underwent damage control surgery with staged Whipple Procedures. However, pancreaticoduodenectomy at the initial operation is feasible in highly selective patients, depending on the extent of injury, physiologic status, and resuscitation.

BACKGROUND: The incidence of a second de novo pancreatic ductal adenocarcinoma (PDAC) among patients with prior cancer has been reported to be 6%.1,2 however, as survival increases through improvements in systemic therapy, this incidence of a de novo PDAC after prior PDAC may become more prevalent.3-8 In this context, a structured and stepwise approach to a total pancreatectomy for a second de novo PDAC after a prior PDAC treated with a pancreaticoduodenectomy is detailed. PATIENTS: We present two similar cases. The first patient was a 71-year-old female with de novo body PDAC, and the second was a 50-year-old female with de novo tail PDAC. To rule out recurrence, immunohistochemical staining as well as the review of biopsies by two experienced pathologists were employed. Both patients had undergone a laparoscopic pancreatoduodenectomy for PDAC 4 and 3 years prior. Each patient received four cycles of neoadjuvant chemotherapy and underwent a safe laparoscopic total pancreatectomy. TECHNIQUE: Prior to surgery, three-dimensional anatomic and port site modeling is performed to optimize the understanding of the spatial relationship between the tumor, blood vessels, and adjacent organs involved. The port site modeling (including pneumoperitoneum simulation) focuses on the optimal port set-up for dissecting the biliopancreatic limb off the portal vein. Following complete mobilization of the biliopancreatic limb, the biliopancreatic limb is staple-divided between the hepatico- and pancreaticojejunostomy. Great care must be taken to avoid accidental staple injury to the hepatic artery or celiac trunk. The remainder of the dissection is akin to a standard distal pancreaticosplenectomy. CONCLUSION: Virtual pancreatectomy modeling facilitates an optimal set-up for the critical step of this case, i.e. dissection of the pancreaticojejunostomy off the portal vein. Early division of the biliopancreatic limb between hepatico- and pancreatojejunostomy is crucial to facilitating the remainder of the dissection. Laparoscopic total pancreatectomy for a de novo PDAC after laparoscopic pancreaticoduodenectomy may become more common as survival of patients with prior PDAC improves over time.

BACKGROUND: The optimal approach for the safe implementation and education of robotic pancreaticoduodenectomy (RPD) remains unclear. Prolonged operation time may cause surgeon fatigue and result in perioperative complications. To solve this issue, our department adopted task division by the console surgeon turnover between resection and reconstruction in 2022. METHODS: This study retrospectively investigated consecutive patients who underwent RPD from November 2009 (initial introduction of RPD) to December 2023. The analysis excluded patients who underwent concomitant resection of other organs. The cases performed by a single console surgeon (single approach) were compared with those performed by two or more console surgeons (multiple approach). RESULTS: This study analyzed 85 consecutive RPD cases, including 51 with the single approach and 34 with the multiple approach. The operation time was significantly shorter (832 vs. 618 min, p < 0.001), and the postoperative major complication was less frequent (45% vs. 12%, p = 0.003) in the multiple approach group, although less experienced surgeons performed the multiple approach (number of RPD experiences: 19 cases vs. 5 cases, p < 0.001). The console surgeon turnover between the resection and reconstruction resulted in a safe pancreatojejunostomy performed by the less experienced surgeon (number of pancreatic reconstruction experiences: 6.5 vs. 14 cases, p = 0.010). Surgeons who started RPD with a multiple approach observed a reduction in surgical time and a lower incidence of complications earlier than those who started with a single approach. CONCLUSION: Task division during the early introduction phase of RPD using the multiple approach demonstrated potential contributions to improved surgical outcomes and enhanced educational benefits.

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.
