RESUMO
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.

BACKGROUND: Robotic pancreaticoduodenectomy (RPD) is technically demanding, and 20-50 cases are required to surpass the learning curve. This study aimed to show our experience of 76 cases from the introduction of RPD and report the changes in surgical results owing to the accumulation of cases and optimization of surgical techniques. METHODS: A total of 76 patients who underwent RPD between November 2009 and May 2023 at the Fujita Health University Hospital were divided into three groups: competency (n = 23, Nov 2009-Mar 2020), proficiency (n = 31, Apr 2020-Jun 2022), and mastery (n = 22, Jul 2022-May 2023) phases. In the mastery phase, for the education of new surgeons and maintenance of surgical quality, optimization of the procedure, including hanging maneuver with or without stapling transection of the retropancreatic tissue was implemented. The surgical outcomes were compared between the groups. RESULTS: The mean operation time decreased over time despite of the participation of newly started operators in mastery phase [competency: 921.5 min (IQR 775-996 min) vs. proficiency: 802.8 min (IQR 715-887 min) vs. mastery: 609.2 min (IQR 514-699 min), p < 0.001]. Additionally, Clavien-Dindo ≥ grade IIIa complications decreased from 52.2% in competency phase to 35.5% and 9.1% in proficiency and mastery phases, respectively (p = 0.005). CONCLUSION: Operation time and major complications decreased along the learning curve from the introduction of RPD. In addition, optimization of the procedure, including hanging maneuver of the retropancreatic tissue seemed to be effective in reducing operation time and educating new RPD surgeons.

BACKGROUNDS: Pancreatojejunostomy is a technically demanding procedure during robotic pancreaticoduodenectomy (RPD). Modified Blumgart anastomosis (mBA) is a common method for the pancreatojejunostomy; however, the technical details for robotic mBA are not well established. During RPD, we performed a mBA for the pancreatojejunostomy using thread manipulation with gauze and an additional assist port. METHODS: Patients who underwent robotic pancreatoduodenectomy at Fujita Health University from November 2009 to May 2023 were retrospectively investigated, and technical details for the robotic-modified Blumgart anastomosis were demonstrated. RESULTS: Among 78 patients who underwent RPD during the study period, 33 underwent robotic mBA. Postoperative pancreatic fistula (POPF) occurred in six patients (18%). None of the patients suffered POPF Grade C according to the international study group of pancreatic surgery definition. The anastomotic time for mBA was 80 min (54-125 min). CONCLUSION: Robotic mBA resulted in reasonable outcomes. We propose that mBA could be used as one of the standard methods for robotic pancreatojejunosotomy.

INTRODUCTION: Although tumor size (TS) is known to affect surgical outcomes in laparoscopic liver resection (LLR), its impact on laparoscopic major hepatectomy (L-MH) is not well studied. The objectives of this study were to investigate the impact of TS on the perioperative outcomes of L-MH and to elucidate the optimal TS cutoff for stratifying the difficulty of L-MH. METHODS: This was a post-hoc analysis of 3008 patients who underwent L-MH at 48 international centers. A total 1396 patients met study criteria and were included. The impact of TS cutoffs was investigated by stratifying TS at each 10-mm interval. The optimal cutoffs were determined taking into consideration the number of endpoints which showed a statistically significant split around the cut-points of interest and the magnitude of relative risk after correction for multiple risk factors. RESULTS: We identified 2 optimal TS cutoffs, 50 mm and 100 mm, which segregated L-MH into 3 groups. An increasing TS across these 3 groups (≤ 50 mm, 51-100 mm, > 100 mm), was significantly associated with a higher open conversion rate (11.2%, 14.7%, 23.0%, P < 0.001), longer operating time (median, 340 min, 346 min, 365 min, P = 0.025), increased blood loss (median, 300 ml, ml, 400 ml, P = 0.002) and higher rate of intraoperative blood transfusion (13.1%, 15.9%, 27.6%, P < 0.001). Postoperative outcomes such as overall morbidity, major morbidity, and length of stay were comparable across the three groups. CONCLUSION: Increasing TS was associated with poorer intraoperative but not postoperative outcomes after L-MH. We determined 2 TS cutoffs (50 mm and 10 mm) which could optimally stratify the surgical difficulty of L-MH.

Many studies conducted previously have reported that due to lockdowns or stay-at-home orders associated with the COVID-19 pandemic in April 2020 residential power consumption has increased in countries, particularly in cities worldwide. This study compared the power consumption of 1,339 detached houses in Japan over the past three years as well as a year after the pandemic and analyzed living behavioral changes in the 12 months after the pandemic using a questionnaire survey of occupants. As of March 2021, which is after 12 months of the beginning of the pandemic, it was confirmed that the way of life had returned to almost normal, and as a factor in increasing consumption, working from home would remain the only behavioral change that may take root in Japanese society.
RESUMO
PURPOSE: Anatomic isolated liver segmentectomy 8 (ILSeg8) for malignancies remains technically challenging. The feasibility, safety, and oncologic validity of laparoscopic ILSeg8 are undefined, and thus were evaluated in comparison with the open approach. METHODS: This study enrolled 35 open and 29 laparoscopic ILSeg8 cases of hepatocellular carcinoma (n = 47), metastatic liver tumors (n = 16), and intrahepatic cholangiocarcinoma (n = 1) at our institution. The surgical techniques were based on the pre-hepatectomy extrahepatic Glissonian pedicle control, followed by cranial-to-caudal parenchymal dissection from the hepatic vein root side. The short- and long-term outcomes after ILSeg8 were retrospectively evaluated and compared between the open and laparoscopic approaches using 1:1 propensity score matching (PSM). RESULTS: Both before and after PSM, the laparoscopic ILSeg8 group had significantly less blood loss, lower postoperative serum bilirubin level, and a shorter postoperative hospital stay than the open group. The overall survival rates were comparable between the laparoscopic and open groups before (P = 0.017) and after (P = 0.043) PSM, with the similar recurrence-free survival rates between the groups. In a multivariable analysis of the cohort before PSM (n = 64), the laparoscopic approach was identified to be an independent factor for favorable overall survival (hazard ratio = 0.20, P = 0.039). CONCLUSION: Laparoscopic ILSeg8 using the extrahepatic Glissonian approach and hepatic vein root at first parenchymal dissection was feasible, safe, and oncologically acceptable. In ILSeg8 for malignancy, the laparoscopic approach potentially confers short-term advantages over the open approach with comparable long-term outcomes in select patients.

We examined the methods for recovering residual anticancer drugs in medical settings to prevent health hazards caused by exposure to anticancer drugs. Presently, the lactose hydrate recovery rates(Lac, an alternative sample for an anticancer drug)were determined using 2 drug recovery methods that are based on a procedure manual(procedure manual method) and smart remote support(remote support method). Using the procedure manual method, 5 healthcare workers recovered Lac after receiving a detailed face-to-face methodological explanation. Using the remote support method, 3 healthcare workers recovered Lac regarded by an instructor waiting at a remote site without using a procedure manual. As a result, the Lac recovery rates were>80% for both methods; however, they showed the need for improvement. Eventually, the issues found presently will be resolved to improve the working environments of healthcare workers, caregivers, and medical service providers.

BACKGROUND: Cigarette smoking harms nearly every organ, including the heart and lungs. A comprehensive assessment of both cardiac and respiratory function is necessary for evaluating the direct effects of tobacco on the heart. However, few previous studies examining the effects of cigarette smoking on cardiac function included an assessment of lung function. This cross-sectional study investigated the influence of cigarette smoking on cardiac function, independent of respiratory function. METHODS: We retrospectively reviewed the medical records of 184 consecutive cases that underwent both spirometry and transthoracic echocardiography around the same time (within 1 month) in one hospital from April 2019 to March 2020. Participants were classified into three groups based on lifetime smoking exposure (pack-years): non-smoker (n = 49), low exposure (1-20 pack-years, n = 40), and high exposure (≥ 20 pack years, n = 95). Multiple linear regression analysis was used to assess the relationship among cigarette smoking, and cardiac and respiratory functions. The relationship between selected dependent variables and lifetime pack-years was assessed in two models with multiple linear regression analysis. Model 1 was adjusted for age and male sex; and Model 2 was adjusted for Model 1 plus forced expiratory volume percentage in 1 s and forced vital capacity percentage. RESULTS: Compared with the non-smokers, the participants with high smoking exposure had lower left ventricular (LV) systolic function and larger LV size. Multiple linear regression analysis revealed a negative association of cumulative lifetime pack-years with LV and right ventricular (RV) systolic functions, even after adjustment for age, sex, and spirometric parameters (forced expiratory volume percentage in 1 s and forced vital capacity percentage). Meanwhile, there was no significant association of smoking exposure with LV diastolic function (E/e' and E/A) and RV diastolic function (e't and e't/a't). CONCLUSIONS: Cumulative smoking exposure was associated with a negative effect on biventricular systolic function in patients with relatively preserved cardiac function, independent of respiratory function.

Japan is an aging society, and the incidence of diseases related to aging, such as pneumonia, heart failure, vertebral compression fracture (VCF), is increasing. Prolonged hospital stays are becoming a serious social problem, leading to elevated medical expenses. Thus, shortening the period of hospitalization is important. This study aimed to reveal determinants associated with prolonged hospital stays for patients with VCF. Our institution is the primary hospital in a rural area in the Kanto region of Japan. Altogether, 110 patients with a VCF, aged 65 years or older, including 79 women, were divided into two groups according to the average hospital stay period of 28 days: the long-stay group (mean stay 40.0 ± 11.6 days, n = 39) and the short-stay group (mean stay 20.6 ± 4.4 days, n = 71). Notably, the short-stay group included 55 women. Multivariate logistic regression analyses in male showed no variates significantly associated with prolonged hospitalization. By contrast, multivariate logistic regression analyses in female showed requiring emergency transportation to hospital was significantly associated with prolonged hospitalization [odds ratio 7.69, 95% confidence interval 1.13-52.29, P = 0.04]. In conclusion, this study implies that patients with better levels of activities of daily living are able to walk alone sooner and are easily discharged. Furthermore, the patient requiring emergency transportation might be in a poor social living environment, such as living alone. These results may give us a good opportunity to re-consider fundamental problems surrounding the elderly.

A 61-year-old woman was admitted to our hospital with progressive dyspnea on exertion. Chest X-rays and computed tomography (CT) showed elevation of the left diaphragm and atelectasis of the left lung. Eventration of the diaphragm was performed. The redundant diaphragm was plicated with vertical mattress sutures and reinforced by the suturing of the remnant diaphragm to the diaphragm near to the chest wall. During the thoracoscopic procedures, thoracoscopic examination from a small part of the resected diaphragm was conducted simultaneously to ensure safety and avoid damage to intra-abdominal organs. After plication, dyspnea on exertion was resolved and the patient was discharged on the 9th post-operative day.

Ubiquitin-dependent proteolysis is an important mechanism that suppresses the beta-catenin transcription factor in cells without Wnt stimulation. A critical step in this regulatory pathway is to create a SCF(beta-TrCP) E3 ubiquitin ligase binding site for beta-catenin. Here we show that the SCF(beta-TrCP) binding site created by phosphorylation of beta-catenin is highly vulnerable to protein phosphatase 2A (PP2A) and must be protected by the adenomatous polyposis coli (APC) tumor suppressor protein. Specifically, phosphorylated beta-catenin associated with the wild-type APC protein is recruited to the SCF(beta-TrCP) complex, ubiquitin conjugated, and degraded. A mutation in APC that deprives this protective function exposes the N-terminal phosphorylated serine/threonine residues of beta-catenin to PP2A. Dephosphorylation at these residues by PP2A eliminates the SCF(beta-TrCP) recognition site and blocks beta-catenin ubiquitin conjugation. Thus, by acting to protect the E3 ligase binding site, APC ensures the ubiquitin conjugation of phosphorylated beta-catenin.

Non-occlusive mesenteric ischemia (NOMI), leading to intestinal gangrene without a demonstrable occlusion in the mesenteric artery, is a rare condition with extremely high mortality. We report a case of NOMI diagnosed preoperatively by computed tomography and treated successfully with surgery, assisted by indocyanine green (ICG) fluorescence in the HyperEye Medical System (HEMS), a new device that can simultaneously detect color and near-infrared rays under room light. This allowed for precise intraoperative evaluation of the mesenteric and bowel circulation. Although the necrotic bowel wall of the distal ileum and the segmental ischemia of the jejunum were visible, the jejunum was finally preserved because perfusion of ICG fluorescence was confirmed. The patient, an 84-year-old man, had an uneventful postoperative course and is alive without critical illness 8 months after surgery. We report this case to demonstrate the potential effectiveness of HEMS during surgery for NOMI.

(1) Background: With the increasing demand for repeat hepatectomy, preventing perihepatic adhesion formation following initial hepatectomy is crucial. Adhesion-preventative barriers, like the new spray-type AdSprayTM (Terumo Corporation, Tokyo, Japan), have been proposed to reduce adhesion risk. However, data on their safety in minimally invasive hepatectomy (MIH) remain scarce. This is the first prospective study to evaluate the safety and feasibility of AdSprayTM in MIH. (2) Methods: A total of 124 patients who underwent MIH with AdSprayTM and 20 controls were analyzed. Subgroup analysis according to the AdSpray™ application area was conducted. Major complications were assessed using the Clavien-Dindo classification. Moreover, intraperitoneal pressure during AdSpray™ application was monitored in 20 cases. (3) Results: Major complications occurred in 6.4% of the patients, which was comparable to that in open hepatectomy. Intraperitoneal pressure remained stable below 12 mmHg during AdSpray™ application without any complications. No significant difference in complication rates was observed among subgroups. However, a potential increase in intra-abdominal abscess formation was suspected with AdSpray™ application to the resected liver surfaces. (4) Conclusions: AdSpray™ can be safely used in MIH; however, further research is needed to confirm the appropriacy of using AdSpray™, particularly over resected liver surfaces. Overall, AdSpray™ is a promising tool for enhancing the safety of MIH.
RESUMO
Accurate minimally invasive anatomic liver (sub)segmentectomy (MIAS) is technically demanding and not yet standardized, and its surgical outcomes are undefined. To study the impact of the minimally invasive approach on perioperative outcomes of anatomic liver (sub)segmentectomy (AS), we retrospectively studied and compared perioperative outcomes of 99 open AS (OAS) and 112 MIAS (laparoscopic 77, robotic 35) cases using the extrahepatic Glissonean approach, based on the 1:1 propensity score matched analyses. After matching (71:71), MIAS was superior to OAS in terms of blood loss (p < 0.0001), maximum postoperative serum total bilirubin (p < 0.0001), C-reactive protein (p = 0.034) levels, R0 resection rate (p = 0.021), bile leak (p = 0.049), and length of hospital stay (p < 0.0001). The matched robotic and laparoscopic AS groups (30:30) had comparable outcomes in terms of operative time, blood loss, transfusion, open conversion, postoperative morbidity and mortality, R0 resection, and hospital stay, although the rate of Pringle maneuver application (p = 0.0002) and the postoperative aspartate aminotransferase level (p = 0.002) were higher in the robotic group. Comparing the matched posterosuperior (sub)segmentectomy cases or unmatched repeat hepatectomy cases between MIAS and OAS, we observed significantly less blood loss and shorter hospital stays in MIAS. Robotic AS yielded comparable outcomes with laparoscopic AS in the posterosuperior (sub)segmentectomy and repeat hepatectomy settings, despite the worse tumor and procedural backgrounds in robotic AS. In conclusion, various types of MIAS standardized by the extrahepatic Glissonean approach were feasible and safe with more favorable perioperative outcomes than those of OAS. Although robotic AS had almost comparable outcomes with laparoscopic AS, robotics may serve to decrease the surgical difficulty of MIAS in selected patients undergoing posterosuperior (sub)segmentectomy and repeat hepatectomy.
RESUMO
Situs inversus complicates diagnosis and treatment due to the mirrored organ placement in relation to normal anatomy. This report describes a 78-year-old female patient with situs inversus totalis who underwent laparoscopic cholecystectomy and laparoscopic common bile duct exploration for cholecystolithiasis and choledocholithiasis. Utilizing the "French mirror technique" for port placement, the surgeon adeptly mirrored standard maneuvers with a 2-mm needle forceps in the left hand and a 5-mm forceps in the right in a reversed anatomical setting. This technique maintained familiar hand movements, despite the patient's unique anatomy. The surgeon applied transcystic ductal bile duct exploration, using choledochoscopy for duct exploration and a basket catheter for stone removal. Laparoscopic cholecystectomy and common bile duct exploration through the transcystic ductal route are viable and effective for patients with situs inversus.

Pancreatic tumor enucleation is a procedure that can preserve pancreatic function and is sometimes performed using a minimally invasive approach. Recently, a single-port robotic platform called da Vinci SP has been developed. However, the technical details of pancreatic tumor enucleation using da Vinci SP have not been reported to date. We report a male patient in his 70s who underwent robotic SP pancreatic tumor enucleation for a pancreatic neuroendocrine tumor. The dissection between the tumor and pancreatic parenchyma was performed using the double bipolar technique. The operative time was 139 min, and the estimated blood loss was 4 mL. The patient had an uneventful recovery and was discharged on the sixth day after the surgery. Robotic SP pancreatic tumor enucleation appears to be a feasible procedure with lower invasiveness and better cosmesis.

Robotic distal pancreatectomy (RDP) has emerged as a minimally invasive approach to left-sided pancreatic tumors. This study aimed to evaluate the efficacy of the robot-assisted approach (RAA) using a laparoscopic articulating vessel-sealing device (LAVSD) during RDP by comparing it with the pure-robotic approach (PRA). Among 62 patients who underwent RDP between April 2020 and December 2023 at Fujita Health University, 22 underwent RAA (the RAA group). In RAA, console surgeons mainly prepared the surgical fields, and assistant surgeons actively dissected the adipose and connective tissues using LAVSD. The surgical outcomes of these patients were compared with those of 40 consecutive patients who underwent RDP with PRA. In total, 28 males and 34 females with a median age of 71 years were analyzed. The console surgeon's prior experience of performing RDP was similar between the groups (RAA; median, 6 [range, 0-36], PRA; median, 5.5 [range, 0-34] cases). The operation time was significantly shorter in the TST group (median, 300.5 [range, 202-557] vs. 363.5 [range, 230-556] min, p = 0.015). Major complications (Clavien-Dindo ≥ grade 3a) occurred less frequently in the RAA group (4.6% vs. 25.0%, p = 0.028). Although the median postoperative hospital stay was slightly shorter in the RAA group (median, 12 [range, 8-38] vs. 14.5 [8-44] days, p = 0.095), no statistically significant difference was observed. Compared with PRA, RAA using LAVSD is found to be safe and feasible in introducing RDP for operators with little experience.

BACKGROUND/PURPOSE: Surgical outcomes and utility of robotic liver resection (RLR) are undefined. METHODS: We retrospectively studied perioperative and long-term outcomes of the single-center 120 RLRs including non-anatomic (NAR, n = 58) and anatomic (AR, n = 62) resections. To evaluate the feasibility and safety of RLR, perioperative outcomes of RLR (n = 103) were compared to those of open (OLR, n = 495) or laparoscopic (LLR, n = 451) resection in liver-only resections without reconstruction, using 1:1 propensity score matching (PSM). The changing trends from the earlier to the later RLR cases were assessed. Long-term outcomes were compared between RLR and LLR. RESULTS: Various types of RLR with different surgical difficulties were performed, with mostly comparable postoperative morbidity between AR and NAR, or among AR subtypes. In segmentectomy and sectionectomy cases, perioperative outcomes significantly improved in the later period. In comparison between PSM-selected OLR and RLR cases (87:87), RLR had significantly longer operative time, less blood loss, and shorter hospital stay. PSM-selected LLR and RLR cases (91:91) showed comparable perioperative outcomes. Overall and recurrence-free survivals after RLR for newly diagnosed hepatocellular carcinoma and colorectal metastasis were comparable to those after LLR. CONCLUSIONS: RLR is applicable to various types of liver resection with acceptable perioperative and long-term outcomes in select patients.
