ABSTRACT
INTRODUCTION: The incidence of Pancreatic cancer is different in different parts of the world. It is a cancer with the worst prognosis of all malignancies. Pancreatic cancer is predominantly a disease of an older population. There are different environmental (modifiable) and non-modifiable risk factors associated with the development of pancreatic cancer. At present, surgical resection is the only potential cure for pancreatic cancer. However, as only 10-20% of the patients have resectable disease at the time of diagnosis. The morbidities associated with surgeries for pancreatic cancers remain high though the post-operative mortality has shown significant reduction in the past few decades. So far, no study has been conducted to investigate pancreatic cancer in Ethiopia. OBJECTIVES: To assess the clinico-pathologic profile, associated factors, surgical management and short-term outcome of patients with pancreatic cancer in Tikur Anbessa Specialized hospital. METHODS: A 5 years retrospective hospital-based cross-sectional study was conducted on 52 patients operated with the diagnosis of pancreatic cancer with either curative or palliative intents. The study period was from April 2016 to July 2021. The data collected includes demographic profile, associated risk factors and comorbidities, clinical presentations, biochemical parameters, pathologic features of the tumors as well as type of treatment offered and short term treatment outcome. The data was analyzed using SPSS version 25. RESULT: The mean and median age of patients was 54.1 and 54.5% respectively. Males constitute about 52% the patients. 21% of the patients have potential risk factors; whereas only 10 (19.2%) of the patients had medical comorbidities. Median duration of symptoms at diagnosis was 12 weeks. Abdominal pain (88.5%) was the most common presenting symptom followed by anorexia (80.8%) and significant weight loss (78.8%), while 71.2% of the patients have jaundice. On clinical evaluation, 69.2% were jaundiced, while 34.6% had a palpable gallbladder. More than two third of patients presented with advanced disease. 76.9% of the tumors are located in the head of pancreas. More than three quarters (77%) of the surgeries performed were palliative. Postoperative morbidity and mortality were 19.2% and 3.8% respectively. CONCLUSION: Age at first diagnosis of pancreatic cancer is relatively earlier in our setup. Most patients present with advanced condition, only amenable for palliative measures. The post-operative morbidity and mortality are more or less comparable with similar studies. The need for adjuvant therapy in pancreatic cancer should be emphasized.

BACKGROUND Adenocarcinomas and pancreatic neuroendocrine tumors (pNETs) display some similarities and differences. The aim of this study was to compare preoperative data and morphological parameters, and to assess postoperative complications after resection. MATERIAL AND METHODS Data of 162 patients who underwent distal pancreatic resection for neuroendocrine or adenocarcinoma tumor were retrospectively analyzed. After applying inclusion and exclusion criteria, 131 patients were included in the study. The preoperative data analyzed included age, sex, and ASA-PS (American Society of Anesthesiologists Physical Status) grade. The diameter of the pancreatic duct and the texture of the pancreas were analyzed. Postoperative data included grading (G1-G3), the presence of PanIN (pancreatic intraepithelial neoplasia), infiltration of structures, and postoperative complications. RESULTS Patients with adenocarcinoma were statistically older and had a higher ASA-PS class than patients with NET (P<0.001). Statistically significantly more patients with adenocarcinoma had a histopathological diagnosis of G3 (p<0.001). In patients with adenocarcinomas infiltration of structures occurred more frequently. Pancreatic duct diameter ≥3 mm was more common in patients with adenocarcinoma (P=0.045). Clinically significant pancreatic fistulas were more frequent in patients with neuroendocrine tumors (P=0.044). CONCLUSIONS Adenocarcinomas in the pancreatic body and tail are more aggressive, they cause more frequent infiltration of structures, and more often metastasize to lymph nodes compared to NETs. NETs tend to have softer pancreatic texture and higher incidence of clinically significant pancreatic fistulas, but postoperative complications of Clavien-Dindo grade ≥III occur at a similar rate in both groups.

Spleen-preserving distal pancreatectomy offers an alternative surgical approach to the traditional distal pancreatectomy combined with splenectomy for removing benign and low-grade malignant lesions in the distal pancreas, avoiding complications associated with splenectomy. This procedure can be accomplished either by resecting and ligating the splenic vessels (Warshaw technique) or by preserving them (Kimura technique). Currently, the widespread use of minimally invasive surgery has established laparoscopic and robotic approaches for spleen-preserving distal pancreatectomy as valid and safe options for treating such conditions. Our protocol aims to describe how the Warshaw and Kimura techniques of spleen-preserving distal pancreatectomy can be performed robotically. The first patient is a 36-year-old female with a neuroendocrine tumor (NET) in the pancreatic body who underwent a spleen-preserving distal pancreatectomy with the ligation of the splenic vessels (WT). The second patient is a 76-year-old male with chronic pancreatitis presenting with a dilated main pancreatic duct in the tail of the pancreas who underwent a spleen-preserving distal pancreatectomy with a vessel-preserving approach (KT).

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.

We present a combination of distal cholangiocarcinoma of the intrapancreatic common bile duct and intraductal papillary mucinous tumor associated with ductal adenocarcinoma of the pancreatic tail. This clinical case is unique. When analyzing the literature, we found no any case of similar primary multiple malignant tumor. Importantly, final diagnosis of simultaneous malignant pancreatobiliary neoplasia is possible only via intraoperative biopsy after adequate morphological dissection and research of resected organ complex including molecular genetic analysis due to identical histological and immunohistochemical picture of ductal neoplasia.

We demonstrate robot-assisted treatment of a patient with benign pancreatic insulinoma. A 31-year-old patient suffered from attacks of weakness, numbness of the fingertips and «turbidity of consciousness¼ for 2 years. These symptoms occurred on an empty stomach and regressed after eating. We found pancreatic insulinoma. The patient underwent robotic enucleation of pancreatic tumor. Surgery time was 145 min. Postoperative period proceeded without complications. Hyperglycemia up to 10.5 mmol/l on the first postoperative day was followed by normalization after 4 days. The patient was discharged in 6 days after surgery. Minimally invasive robotic enucleation of insulinoma minimizes surgical trauma and provides precise resection of tumor. The key aspect of safe enucleation is localization of tumor at a distance of at least 2 mm from the pancreatic duct.

BACKGROUND Minimally invasive pancreatectomy has become the standard practice for the management of benign and malignant pancreatic tumors. Techniques such as robotic and laparoscopic approaches are known to reduce morbidity by offering benefits such as less blood loss, reduced pain, shorter hospital stays, and quicker recovery times. The indication for repeated minimally invasive pancreatectomy for recurrent or de novo pancreatic neoplasm after primary pancreatic surgery remains debated. CASE REPORT A 50-year-old woman was admitted to our hospital with a diagnosis of an intraductal papillary mucinous neoplasm in the pancreatic head. In 2010, she underwent laparoscopic single-branch resection for a branch-type tumor in the pancreatic uncinate process. During a 5-year follow-up, a de novo intraductal papillary mucinous neoplasm was detected, showing gradual growth and the presence of a mural nodule over the next 7 years. The patient's CEA level was elevated to 7.0 ng/mL. Considering the tumor's progression and the appearance of a mural nodule, we recommended a robot-assisted Whipple procedure. The operation began with laparoscopic adhesiolysis. After detachment of the adhesions and remobilization of the duodenum using the Kocher maneuver, the operation continued with the Da Vinci surgical system. The postoperative period was uneventful, and the patient was discharged on postoperative day 20. Pathological examination revealed intraductal papillary mucinous carcinoma in situ with negative resection margins. CONCLUSIONS This case verifies the safety and feasibility of performing a robotic Whipple procedure for a newly diagnosed pancreatic neoplasm in patients who have previously undergone minimally invasive pancreatic surgery.

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.

Solid pseudopapillary neoplasm of the pancreas (SPNP) is a rare entity. In this study, we present a woman in her 20's who presented for evaluation of two separate pancreatic masses. On imaging and biopsy, the tail lesion was thought to be a neuroendocrine tumour and the body lesion was thought to be a metastatic lymph node. The patient was brought to the operating room and underwent a distal pancreatectomy and splenectomy. The patient had an uneventful postoperative course and was discharged home on postoperative day 4. Pathology confirmed both masses were consistent with the diagnosis of well-differentiated SPNP with no signs of malignancy including lymphovascular or perineural invasion, or lymph node involvement.

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.

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.

Aims/Background: Insulinoma is an extremely rare condition in pediatric patients. This study aims to examine the pathological and clinical characteristics of pediatric insulinoma. Methods: A retrospective, single-center study was conducted involving five pediatric patients diagnosed with insulinoma. The study involved evaluating the postoperative status of the patients during follow-up and analyzing their clinical manifestations, diagnostic work-up, pathological findings, and therapeutic approaches. Results: The study cohort comprised four males and one female, aged between 4 and 9 years. Common symptoms included dizziness and fatigue. The insulinomas were located in various parts of the pancreas: two in the head, one in the neck, one in the body, and one in the tail. After undergoing subtotal pancreatectomy, four patients experienced no side effects during a follow-up period of 41 to 153 months. One patient, who underwent an incomplete pancreatic resection, required ongoing postoperative treatment with 150 mg Creon due to pancreatic enzyme deficiency. Postoperative pathological results indicated that all cases were low-grade neuroendocrine tumours, classified as grade 1 (G1) or grade 2 (G2). Two cases exhibited capsule invasion, and one case showed microvascular invasion. Despite these invasions, no recurrences or metastases have been observed to date. Conclusion: Surgical resection is a viable treatment option for pediatric insulinoma, yielding a favorable prognosis. The presence of capsular and microvascular invasions does not seem to affect the overall prognosis in these cases.

Pancreatic ductal adenocarcinoma (PDAC) ranks among the 15 most prevalent cancers globally, characterized by aggressive growth and late-stage diagnosis. Advances in imaging and surgical techniques have redefined the classification of pancreatic PDAC into resectable, borderline resectable, and locally advanced pancreatic cancer. While surgery remains the most effective treatment, only 20% of patients are eligible at diagnosis, necessitating innovative strategies to improve outcomes. Therefore, traditional treatment paradigms, primarily surgical resection for eligible patients, are increasingly supplemented by neoadjuvant therapies (NAT), which include chemotherapy, radiotherapy, or a combination of both. By administering systemic therapy prior to surgery, NAT aims to reduce tumor size and increase the feasibility of complete surgical resection, thus enhancing overall survival rates and potentially allowing more patients to undergo curative surgeries. Recent advances in treatment protocols, such as FOLFIRINOX and gemcitabine-nab-paclitaxel, now integral to NAT strategies, have shown promising results in increasing the proportion of patients eligible for surgery by effectively reducing tumor size and addressing micrometastatic disease. Additionally, they offer improved response rates and survival benefits compared to traditional regimes. Despite these advancements, the role of NAT continues to evolve, necessitating ongoing research to optimize treatment regimens, minimize adverse effects, and identify patient populations that would benefit most from these approaches. Through a detailed analysis of current literature and recent clinical trials, this review highlights the transformative potential of NAT in managing PDAC, especially in patients with borderline resectable or locally advanced stages, promising a shift towards more personalized and effective management strategies for PDAC.

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.

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: Radical antegrade modular pancreato-splenectomy (RAMPS) has been largely described in left-sided pancreatic cancers.1.J Hepato-Biliary-Pancreat Sci 29:1156-1165 Its prognostic advantage is not clear, although a theoretical improvement in R0 resection rate has been shown.2.J Am Coll Surg 204:244-249 Furthermore, RAMPS is usually carried out without adrenal gland removal, the so-called anterior RAMPS, while extending the resection to the adrenal plane could impair perioperative outcomes.3.HPB 25:311-319 METHODS: A 40 mm pancreatic ductal adenocarcinoma (PDAC) was found in a 70-year-old patient. Tumor infiltrates the adrenal gland and a robotic posterior RAMPS was indicated. RESULTS: After sectioning the splenic vessels and the pancreatic neck, the dissection was directed vertically in a sagittal plane along the left border of the superior mesenteric artery to identify the left renal vein. Our dissection plane was then directed on a caudo-cranial axis, after identification of the left renal artery and below the adrenal gland. The resection was also delimitated medially by the left borders of the superior mesenteric artery and the aorta, and posteriorly by the renal parenchyma. Postoperative course was marked by a biochemical leak. The patient was discharged on postoperative day (POD) 5 and the drain removed at POD 18. Pathological examination confirmed a pT2N2 PDAC with negative margins, with 4/18 positive nodes. CONCLUSIONS: The robotic platform is routinely employed in pancreatic surgery. Thanks to its increased degree of movement, its dexterity, and the magnification, this approach can help surgeons with vascular identification and control, in performing extended lymphadenectomies, and finding the correct planes of dissection. All these elements are crucial in a well-performed posterior RAMPS.

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.

PURPOSE: We describe details and outcomes of a novel technique for optimizing the surgical field during robotic distal pancreatectomy (RDP) for distal pancreatic lesions, which has become common with potential advantages over laparoscopic surgery. METHODS: For suprapancreatic lymph node dissection and splenic artery ligation, we used the basic center position with a scope through the midline port. During manipulation of the perisplenic area, the left position was used by moving the scope to the left medial side. The left lateral position is optionally used by moving the scope to the left lateral port when scope access to the perisplenic area is difficult. In addition, early splenic artery clipping and short gastric artery dissection for inflow block were performed to minimize bleeding around the spleen. We evaluated retrospectively the surgical outcomes of our method using a scoring system that allocated one point for blood inflow control and one point for optimizing the surgical view in the left position. RESULTS: We analyzed 34 patients who underwent RDP or R-radical antegrade modular pancreatosplenectomy (RAMPS). The left position was applied in 14 patients, and the left lateral position was applied in 6. Based on the scoring system, only the 0-point group (n = 8) had four bleeding cases (50%) with splenic injury or blood pooling; the other 1-point or 2-point groups (n = 13, respectively) had no bleeding cases (p = 0.0046). CONCLUSION: Optimization of the surgical field using scope transition and inflow control ensured safe dissection during RDP.
