PURPOSE: Although robotic liver resection (RLR) has gained popularity worldwide, limited liver resection remains the mainstay of RLR. This study aimed to investigate the effect of parameters, including liver transection depth (LTD), on surgical difficulty in limited RLR compared with limited laparoscopic liver resection (LLR). METHODS: This retrospective study included 105 patients who underwent limited RLR (n = 56) or LLR (n = 49) at our institution between January 2018 and December 2024. After comparing outcomes of RLR and LLR, multivariate analyses were performed to examine effect of LTD on surgical difficulty (defined as prolonged operative time). Moreover, outcomes stratified by LTD cut-off values were compared between the groups. RESULTS: Median LTD was similar between groups (RLR vs. LLR: 2.6 vs. 2.6 cm, P = 0.77). LTD was significantly correlated with operative time for both procedures (RLR, R² = 0.07, P = 0.042; LLR, R² = 0.08, P = 0.046). Multivariate analyses demonstrated that LLR (odds ratio, 6.9; P < 0.001) and LTD (odds ratio, 2.0; P = 0.004) were significant risk factors of surgical difficulty. Among patients with deeper LTD (> 2.5 cm), the RLR group had significantly shorter operative time (145 vs. 231 min, P < 0.001), less blood loss (nil vs. 100 mL, P = 0.006), and a higher rate of textbook outcomes (76.7% vs. 42.3%, P = 0.01). CONCLUSION: This study investigated impact of LTD on surgical outcomes in patients who underwent limited RLR compared to those who underwent limited LLR. LTD may be a useful parameter for estimating surgical difficulty in limited RLR. Moreover, robotic surgery may be favorable for deeper and limited liver resections.

Failure to rescue (FTR), defined as mortality after major postoperative complications, is a crucial indicator of surgical quality. Although mortality rates after hepatectomy have declined owing to improved surgical techniques and perioperative care, FTR remains a major concern. This review synthesizes the current evidence on the risk factors contributing to FTR after hepatectomy and explores multidisciplinary strategies to reduce its rate. Post-hepatectomy liver failure, hemorrhage, bile leakage, and sepsis commonly precede FTR. Risk factors for FTR are multifactorial and include patient-, procedure-, and system-related factors. Higher procedural volumes are associated with lower FTR rates, likely due to better infrastructure, experienced personnel, and access to rapid interventions. Strategies to reduce the FTR rate include preoperative optimization, intraoperative precision, and vigilant postoperative surveillance. System-level approaches, such as multidisciplinary rounds, standardized escalation protocols, and a robust institutional safety culture, are also pivotal. Future innovations, such as predictive analytics, artificial intelligence, and wearable monitoring devices, offer considerable potential for the early detection of complications. Centralization of complex liver surgeries to high-volume centers is recommended to enhance team preparedness. This review emphasizes the importance of adopting a comprehensive, proactive, and technologically integrated approach to reduce the FTR rate after hepatectomy and improve patient survival.

Background/Objectives: Although neoadjuvant chemotherapy (NAC) is not universally recommended for resectable pancreatic ductal adenocarcinoma (PDAC), NAC with gemcitabine plus S-1 (NAC-GS) has become a commonly used regimen for resectable PDAC in Japan. Furthermore, the impact of achieving textbook outcomes (TO) in patients receiving NAC-GS remains unclear. Methods: This retrospective study included 265 patients who were diagnosed with resectable PDAC at our institution between January 2009 and December 2023. Patients were categorized into two groups: the NAC-GS group (n = 81; 2019-2023) and the upfront surgery (UFS) group (n = 164; 2009-2018). After comparing the clinical outcomes between groups, multivariate analyses for survival were performed. Additionally, outcomes stratified by the achievement of the modified TO were analyzed in the NAC-GS group. Results: The completion rate of NAC-GS was 90.1%. Patients in the NAC-GS group exhibited significantly longer survival than those in the UFS group (2-year recurrence-free survival: 61.4% vs. 37.9%, p < 0.01; 2-year overall survival: 83.2% vs. 61.2%, p < 0.01). Multivariate analyses identified lymph node metastasis, NAC-GS induction, and completion of adjuvant chemotherapy as factors significantly associated with improved survival. Moreover, among patients who received NAC-GS, those who achieved modified TO demonstrated significantly longer survival than those who did not. Conclusions: This study demonstrated the clinical efficacy of NAC-GS in patients with resectable PDAC. Induction of NAC-GS was significantly associated with improved long-term outcomes. In multidisciplinary treatment strategies for PDAC, achieving a modified TO may lead to improved survival of patients undergoing NAC-GS.

Pancreatoduodenectomy (PD) after esophagectomy with gastric conduit reconstruction is technically challenging. Preserving the blood supply of the gastric conduit is crucial in performing PD after esophagectomy. We report the case of a 66-year-old man who underwent gastroduodenal artery-preserving PD after esophagectomy with gastric conduit reconstruction for intraductal papillary mucinous neoplasm. The patient developed pseudoaneurysm rupture postoperatively, but was successfully treated with interventional radiology. Precise assessment is important in developing a surgical strategy depending on the patient's specific anatomy and tumor characteristics. Moreover, special attention should be paid to avoid accidental injuries of the gastric conduit and gastric vessels during surgery.

Background/Objectives: Due to the increasing incidence of pancreatic and periampullary cancers with advancing age, coupled with the growing evidence supporting minimally invasive pancreatectomy, the demand for such procedures is rising. However, data on the feasibility of robotic pancreatectomy in octogenarian patients remain scant. This study aimed to investigate overall outcomes of robotic pancreatectomy and evaluate its safety and feasibility in octogenarian patients. Methods: A multicenter, retrospective study was conducted, including 380 patients who underwent robotic pancreatectomy at two high-volume centers in Japan from April 2020 to December 2024. Using prospectively collected data, we compared outcomes between younger patients (<80 years) and octogenarian patients (≥80 years). Multivariable logistic regression analyses were performed to assess the impact of age on postoperative outcomes. Results: Among the 380 patients, with a median age of 72 (interquartile range: 61-77) years, 213 underwent robotic pancreatoduodenectomy (RPD), and 167 underwent robotic distal pancreatectomy (RDP). Octogenarian patients were found to have more comorbidities and a higher incidence of malignant diseases. Octogenarians experienced significantly longer hospital stays post-RPD (22 [octogenarian; n = 36] vs. 14 [younger; n = 177] days, p < 0.001) and post-RDP (14 [n = 23] vs. 10.5 [n = 144] days, p = 0.02), yet their perioperative outcomes were comparable. Multivariable analyses indicated that age (≥80 years) was not a significant risk factor for major complications following robotic pancreatectomy (odds ratio, 1.33; 95% confidence interval, 0.59-2.84; p = 0.479). Conclusions: This multicenter study conducted at high-volume centers suggests that robotic pancreatectomy can be safely performed in carefully selected octogenarian patients.

BACKGROUND: The superior mesenteric artery (SMA) approach is crucial for the successful implementation of robot-assisted pancreatoduodenectomy (RPD). Herein, we present a novel technique, the mesenteric route SMA-first approach, for RPD. PATIENTS AND METHODS: A 20-year-old woman with a 50 mm intraductal papillary mucinous neoplasm underwent RPD. As the tumor was large and located close to the mesenteric vessels, we developed the mesenteric route SMA-first approach. RESULTS: Following the mesenteric Kocher maneuver, the mesenteric route SMA-first approach was applied. With appropriate retraction of the pancreatic head, dissection around the mesenteric vessels was performed and their branches were divided. The uncinate process dissection (PL, ph II) was performed via the mesenteric route. This approach facilitated dorsal dissection, particularly around the large tumor. After dissection of the hepatoduodenal ligament, the remaining pancreatic nerve plexus (PL ph I) was dissected. Finally, the pancreas was divided on the superior mesenteric vein, and the specimen was resected. Operative time was 390 min with minimal blood loss. CONCLUSIONS: The mesenteric route SMA-first approach enables uncinate process dissection via the mesenteric route. This technique may be a safe and feasible option for selected patients, such as nonobese individuals with a large pancreatic head tumor near major vessels.

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has the highest mortality rate among all cancers; hence, multidisciplinary treatment is essential for patients with PDAC. Although the resectability status, tumour marker, KRAS circulating tumour DNA (mutKRAS-ctDNA) mutations, and GATA binding 6 (GATA6) expression status are promising prognostic biomarkers, their effective integration before and after surgery remains unclear. METHODS: In this retrospective cohort study, patients with PDAC who had undergone radical resection were enrolled, and pre- and postoperative independent factors associated with poor prognosis were identified using Cox hazard modelling. Risk stratification systems were developed using the identified prognostic factors and investigated for the ability to predict prognosis. RESULTS: A total of 91 patients with PDAC were included (median follow-up duration, 28 months). Borderline resectable or locally advanced cancer at diagnosis, elevated carbohydrate antigen 19-9 (CA19-9) level, and mutKRAS-ctDNA-positive status were identified as independent preoperative factors associated with poor prognosis. The postoperative factors significantly associated with shorter overall survival were low GATA6 expression, elevated CA19-9 level, and mutKRAS-ctDNA-positive status. Finally, the preoperative and postoperative risk scoring systems developed using Cox modelling hazard ratio values could significantly stratify prognosis after curative resection for PDAC. CONCLUSION: A risk stratification system based on liquid biopsy, specialised for each phase (pre- and post-surgery), has been proven to be a useful, simple, and practical prognostic prediction clinical tool to determine the optimal multidisciplinary treatment protocol for PDAC.

BACKGROUND: Difficulty scoring systems (DSS) have been developed to quantify the surgical complexity of laparoscopic distal pancreatectomy (LDP). However, few studies have validated these systems in the context of robotic distal pancreatectomy (RDP). Moreover, the impact of body composition on RDP outcomes remains unexplored. This study aimed to investigate the risk factors of surgical difficulty in RDP, including body composition. METHODS: This retrospective study included 72 consecutive patients who underwent RDP at our institution between April 2021 and October 2024. Using a modified DSS for LDP, patients were divided into three difficulty index groups. The association between the difficulty index and outcomes was investigated. Multivariate analyses were performed to identify risk factors associated with surgical difficulty (prolonged operative time) in RDP. RESULTS: Patients were classified into three difficulty index groups: low (n = 28), intermediate (n = 25), and high (n = 19). Operative time was significantly associated with the surgical index (P = 0.01). Moreover, visceral fat area (VFA) was significantly correlated with operative time (r2 = 0.10, P = 0.008). The multivariate analyses found that VFA (≥ 100 cm2) (odds ratio [OR] 5.03, 95% confidence interval [CI] 1.32-22.4, P = 0.02), malignancy (OR 4.92, 95% CI 1.50-18.9, P = 0.01), and pancreatic resection on the portal vein (OR 4.14, 95% CI 1.24-15.9, P = 0.02) were significant risk factors associated with surgical difficulty. CONCLUSION: VFA could be a novel and useful factor for assessing the surgical difficulty associated with RDP.

BACKGROUND: Internationally, evidence supporting robotic liver resection (RLR) has gradually increased in recent years. However, a standardized protocol for RLR remains lacking. This study describes a surgical protocol and the initial outcomes of RLR in a high-volume center for robotic hepatopancreatobiliary surgery in Japan. METHODS: Patients were placed in the reverse Trendelenburg position, with a supine position for anterolateral tumors and left lateral position for posterosuperior tumors. Our standard RLR protocol involved a two-surgeon technique. Liver parenchymal transection was performed by an assistant using the clamp crush technique with a console, with or without a laparoscopic Cavitron ultrasonic surgical aspirator (CUSA). Surgical techniques, including the tips, tricks, and pitfalls of RLR, are also demonstrated. RESULTS: We performed 113 RLR at our institution for common primary diseases, including hepatocellular carcinoma (n = 52, 46.0%) and metastatic tumors (n = 48, 42.5%) between July 2022 and December 2024. The median operative time and estimated blood loss were 156 min (interquartile range [IQR], 121-209 min) and 20 mL (IQR, 0-100 mL), respectively. During liver parenchymal transection, a laparoscopic CUSA was used in 59 patients (52.2%), and a water-jet scalpel was used in 12 patients (10.6%). The incidence of mortality, major complications, and bile leakage was 0%, 6.2%, and 2.7%, respectively. The median hospital stay was 7 days (IQR, 6-9 days). CONCLUSIONS: We successfully introduced an RLR program using the two-surgeon technique. Safe implementation of RLR can be achieved upon completion of the training program and thorough understanding of the surgical protocols.

INTRODUCTION: Total pancreatectomy (TP) is a technically demanding procedure for patients with multifocal pancreatic diseases. Although the benefits of the superior mesenteric artery (SMA)-first approach for pancreatic cancer (PC) have been reported in pancreatic surgery, few studies have demonstrated surgical techniques of SMA-first approach in TP. METHODS: This report presents our novel SMA-first approach for PC in TP, including six steps. First, the resectability was confirmed (step 1). Next, SMA approach was applied (step 2). In this step, the anterior and left sides of the SMA were dissected, and the left renal vein was confirmed. Following retroperitoneal dissection (step 3), the pancreatic body and tail were completely mobilized (step 4). Subsequently, Whipple procedure was performed with lymphadenectomy around the right side of the SMA (step 5). Finally, hepaticojejunostomy and gastrojejunostomy were performed (step 6). Using SMA-first approach, en bloc resection with adequate lymphadenectomy around the SMA and retroperitoneal dissection was performed. CONCLUSION: The present study presents surgical techniques of TP using the SMA-first approach for PC. This unique approach may be useful to perform TP for PC to obtain negative resection margins.

Pancreatic metastasis of myxoid liposarcoma (MLS) after primary resection is extremely rare. Herein, we present a case of metachronous pancreatic metastasis of MLS that was successfully treated with robotic spleen-preserving distal pancreatectomy (SPDP) using the Warshaw technique. A 60-year-old woman underwent radical resection of a 25-cm MLS in the right thigh after receiving neoadjuvant radiotherapy. The patient developed a 6-cm solitary pancreatic metastasis of the MLS 2 years later. Because no other distant metastases were detected, robotic SPDP (Warshaw technique) was performed. The operative time was 140 min with minimal blood loss. Follow-up at 3 months showed no recurrence. To our knowledge, this is the first report of a case of metachronous pancreatic metastasis of MLS successfully treated with robotic SPDP. Curative resection using minimally invasive surgery should be performed for solitary pancreatic metastases from MLS.

BACKGROUND: Pancreatectomies combined with arterial resection can be indicated for pancreatic cancer. In a pancreatectomy with arterial resection, intraoperative confirmation of blood flow through reconstructed vessels is crucial. This study highlights the usefulness of SPY laser fluorescence imaging during a pancreatoduodenectomy with common hepatic artery resection (PD-CHAR). PATIENT AND METHODS: A 55-year-old man with borderline resectable pancreatic head cancer underwent a PD-CHAR. After confirming tumor resectability, reconstruction of the CHA to the proper hepatic artery was performed. Subsequently, the superior mesenteric vein was reconstructed. RESULTS: SPY laser fluorescence imaging demonstrated arterial blood perfusion to the liver through the reconstructed hepatic artery, followed by perfusion from the portal vein. The operation lasted 493 min, with an estimated blood loss of 400 mL. The postoperative course was uneventful with good arterial blood flow. CONCLUSION: The SPY Portable Handheld Imager could be valuable for visualizing blood flow in reconstructed vessels and assessing tissue perfusion during a pancreatectomy combined with vascular reconstruction.

AIM: Although hepatectomy is a complex surgical procedure, its incidence among older patients has increased due to global aging. However, few studies have focused on the association between age and failure to rescue (FTR) posthepatectomy. This study aimed to investigate the association between age and FTR and develop a risk model for FTR following hepatectomy. METHODS: We analyzed a total of 1371 consecutive patients who underwent primary hepatectomy between July 2003 and September 2022. The patients were divided into three groups according to their age: young-old (<65 years), pre-old (65-74 years), and old group (≥75 years). Additionally, the associations among age, FTR, and risk factors for FTR were investigated. Subsequently, a risk model was developed to predict the FTR. RESULTS: Of the 1371 patients, 373 (27.2%) experienced major complications, and FTR occurred in 15 patients. The older group showed a higher FTR rate (8.4%) than the young-old (1.3%) and pre-old (4.3%) groups (p = 0.03). Multivariate analyses indicated that older age (odds ratio [OR] 1.07; 95% confidence interval [CI] 1.00-1.15; p = 0.045) and American Society of Anesthesiologists Physical Status score ≥3 (OR 4.35; 95% CI 1.24-15.2; p = 0.02) were independent predictive factors for FTR. The risk model exhibited an accuracy with an area under the curve of 0.80 (95% CI 0.69-0.92). Calibration plots of the model revealed a concordance index of 0.73. CONCLUSIONS: This study identified an association between age, FTR, and risk factors for FTR posthepatectomy. Together, our risk model is a clinically relevant, internally validated, and useful tool for predicting FTR posthepatectomy.

BACKGROUND: The superior mesenteric artery (SMA)-first approach for pancreatic cancer (PC) is common surgical technique in pancreaticoduodenectomy. To date, few studies have reported SMA-first approach in robot-assisted pancreaticoduodenectomy (RPD). Herein, we present the anterior SMA-first approach for PC during RPD. PATIENT AND METHOD: A 75-year-old man with resectable PC underwent RPD after neoadjuvant chemotherapy. As pancreatic head tumor contacted with the superior mesenteric vein (SMV), the anterior SMA approach was applied. After the mesenteric Kocher maneuver, the jejunum was divided and the left side of the SMA was dissected. Subsequently, the anterior plane of the SMA was dissected. Following the division of branches from the mesenteric vessels, the SMA was taped, and the circumferential dissection around the SMA was performed to detach the pancreatic neck from the SMA completely. Finally, the dissection between the SMV and the tumor was performed under vascular control to remove the specimen. CONCLUSIONS: The anterior SMA-first approach can be optional in patients with PC undergoing RPD. This unique approach allows for the circumferential dissection around the SMA during RPD.

Background: A difficulty scoring system was developed to estimate the surgical outcomes of laparoscopic liver surgery (LLS); however, the effect of the liver transection area (LTA) on LLS outcomes have not been previously examined. Therefore, this study investigated the predictive significance of the LTA for LLS. Methods: This retrospective study included 106 patients who underwent LLS in our hospital between January 2012 and December 2023. The association of the LTA with the surgical difficulty level and operative time was investigated. Multivariate analyses were performed to identify factors predicting surgical difficulty in LLS. Results: The median LTA and operative time were 62.5 (IQR, 36.0-91.8) cm2 and 250 (IQR, 195-310) minutes, respectively. The LTA was significantly associated with surgical difficulty as evaluated using the IWATE Criteria. Moreover, the LTA significantly correlated with operative time (r2 = 0.19, p < 0.001). The multivariable analyses found that the LTA (≥59 cm2) (odds ratio [OR], 6.07; 95% confidence interval [CI], 2.38-16.6; p < 0.001) and the type of LLS (≥segmentectomy) (OR, 3.79; 95% CI, 1.35-11.4; p = 0.01) were significant factors associated with surgical difficulty. Conclusions: The LTA is a useful parameter that reflects the difficulty of LLS.

BACKGROUND: There are several reports on the safety and feasibility of pancreatoduodenectomy (PD) without reconstruction of the small remnant pancreas. However, a few studies have explored central pancreatectomy (CP) for non-reconstructed small remnant pancreases after PD. This study presents a case of CP without pancreatic reconstruction after PD. CASE PRESENTATION: A 58-year-old man with cerebral palsy underwent PD for distal cholangiocarcinoma. Three years postoperatively, a 12-mm tumor was detected in the remnant pancreatic body and diagnosed as a pancreatic neuroendocrine neoplasm. Surgical resection was performed, because the tumor was enlarged and chemotherapy resistant. The afferent loop with pancreatojejunostomy anastomosis was dissected, and CP, including pancreatojejunostomy anastomosis, was performed. Given the remnant pancreas was hard and atrophic, the pancreatic tail was transected using a stapler without reconstructing the small remnant pancreas. The patient experienced no postoperative complications including postoperative pancreatic fistula, and the endocrine function of the pancreas was preserved. CONCLUSIONS: We present a case of remnant pancreatic CP that did not require reconstruction after PD. Preservation of the small remnant pancreas without reconstruction during CP may be feasible to maintain endocrine function in select patients after PD.

A 20-year-old woman presented to our hospital with abdominal pain. Abdominal computed tomography revealed multiple masses in the upper jejunum, which were suspected as lipomas. Partial resection of the small intestine, including the masses, was performed on the same day due to intussusception secondary to the masses. Pathological examination revealed that the masses consisted of mucosa and edematous submucosa with multiple dilated blood vessels and lymphatic ducts without muscularis propria. The masses were diagnosed as multiple muco-submucosal elongated polyps (MSEP), a type of non-neoplastic polyp. MSEP was originally named colonic MSEP, but with the development of endoscopic techniques and imaging tests, similar polyps have been reported to occur not only in the colon but also in the entire intestinal tract. In this case, multiple MSEPs in the upper jejunum caused intussusception. As reported cases of multiple lesions causing intussusception are few, our case may help to clarify the pathogenesis of this disease.

BACKGROUND: A hematoma that gradually increases over a chronic course of months or longer is defined as a chronic expanding hematoma (CEH). CEHs often develop in the limbs and on body surfaces that are susceptible to external stimuli. CEHs in the intrathoracic or intraperitoneal organs are uncommon, with liver CEHs being particularly rare worldwide. CASE PRESENTATION: A 57-year-old woman was previously diagnosed with a giant cyst in the right liver lobe, with a longer axis of approximately 15 cm. Abdominal ultrasonography findings suggested a complex cyst, and she was referred to our hospital for further inspection. Although CEH was suspected, it was difficult to exclude malignant diseases such as intraductal papillary neoplasm of the bile duct and cystadenocarcinoma. There was a possibility of malignant disease and the exclusion of surrounding organs due to tumor growth. Therefore, a right hepatectomy was performed. Pathological examination revealed a pseudocyst containing a clot, which was consistent with CEH. CONCLUSIONS: CEH rarely occurs in the liver; however, it is necessary to consider CEH when a slow-growing hepatic mass that shows a mosaic pattern on magnetic resonance imaging is found.

We analyzed the clinicopathological characteristics of six patients with duodenal gastrointestinal stromal tumor (dGIST) resected in our hospital between 2005 and 2020. The patients (5 males, 1 female) were aged from 43 to 83 years old (mean: 63.7 years old). With respect to the preoperative diagnosis, one patient was diagnosed with dGIST by a biopsy, and five patients were diagnosed with suspected dGIST by esophagogastroduodenoscopy (EGD). The tumor locations were the third portion in four cases, second portion in one, and fourth portion in one. The pathological stages were I in four patients, II in one, and IIIB in one. All patients were discharged 12.8 days (10-15 days) postoperatively without complications, such as pancreatic fistula or suture deficiency. Regarding the prognosis, all patients are alive without recurrence. The wedge resection is a reasonable option for resection of dGIST and should be routinely considered if technically feasible.
