RESUMO
BACKGROUND: Robotic distal gastrectomy (RDG) with Billroth I (BI) reconstruction is predominantly performed due to its physiological congruence and simplicity. The Intracorporeal Triangular Anastomotic Technique (INTACT) aims to reduce ischemic areas compared to the conventional Delta-shaped anastomosis using the unique characteristics of robotic surgery to standardize procedures, thereby ensuring safe, simple, and reliable reconstruction. This study aims to investigate the efficacy of the INTACT in RDG with BI reconstruction, focusing on its robotic precision in minimizing ischemic zones and improving surgical reliability. SURGICAL TECHNIQUE: The posterior duodenal wall is dissected before reconstruction, and the hepatoduodenal ligament is severed to facilitate passive duodenal manipulation. A quarter-circumference incision is created centrally on the anterior wall of the duodenal stump to avoid excessive tension during anastomosis and to ensure an adequate anastomotic diameter. A small opening is established on the greater curvature of the remaining stomach, and the posterior walls of the stomach and duodenum are joined using a Linear stapler in the first fire. A V-shape is created, and two EndoWrist instruments (robotic first and fourth arms) are utilized to grip and extend the anastomosis diameter, completing the anastomosis with a shared hole closure using the Linear stapler. The robotic arms' features improve the physiological integrity and stability of the BI reconstruction. RESULTS: A total of 81 patients underwent RDG with INTACT from September 2020 to January 2024. The median age was 72 years (range: 31-91), with 49 males and 32 females. The median blood loss was 0 ml (range: 0-200 ml), and the median postoperative hospital stay was 8 days (range: 6-20 days). No cases required reanastomosis during surgery, and no postoperative anastomotic leakage, surgery-related reoperations, or anastomotic strictures were reported. CONCLUSION: INTACT in RDG can be safely performed. The characteristics of the EndoWrist instruments helped in stabilizing the technique, making it a viable option in robotic-assisted surgeries.
RESUMO
BACKGROUND: As the prevalence of gastric cancer rises in aging populations, managing surgical risks and comorbidities in elderly patients presents a unique challenge. The Comprehensive Preoperative Assessment and Support (CPAS) program, through comprehensive preoperative assessments, aims to mitigate surgical stress and improve outcomes by enhancing patient awareness and preparation. This study investigates the efficacy of a CPAS program, incorporating frailty and sarcopenia evaluations, to improve short-term outcomes in elderly gastric cancer patients. METHODS: A retrospective analysis was conducted on 127 patients aged 75 or older who underwent surgery with CPAS between 2018 and August 2023, compared to 170 historical controls from 2012 to 2017. Propensity score matching balanced both groups based on age-adjusted Charlson Comorbidity Index and surgical details. The primary focus was on the impact of CPAS elements such as rehabilitation, nutrition, psychological support, oral frailty, and social support on short-term surgical outcomes. RESULTS: Among 83 matched pairs, the CPAS group, despite 40.4% of patients in the CPAS group and 21.2% in the control group had an ASA-PS score of 3 or higher (P < 0.001), demonstrated significantly reduced blood loss (100 ml vs. 190 ml, P = 0.026) and lower incidence of serious complications (19.3% vs. 33.7%, P = 0.034), especially in infections and respiratory issues. Sarcopenia was identified in 38.6% of CPAS patients who received tailored support. Additionally, the median postoperative hospital stay was notably shorter in the CPAS group (10 days vs. 15 days, P < 0.001), with no in-hospital deaths. These results suggest that personalized preoperative care effectively mitigates operative stress and postoperative complications. CONCLUSION: Implementing CPAS significantly enhances surgical safety and reduces complication rates in elderly gastric cancer patients, emphasizing the critical role of personalized preoperative care in surgical oncology for this demographic.

BACKGROUND: Occupational cholangiocarcinoma is associated with exposure to organic solvents, such as dichloromethane (DCM) and 1,2-dichloropropane (DCP). This report describes a case of occupational cholangiocarcinoma detected through regularly imaging following the discovery of elevated serum γ-glutamyl trans peptidase (γ-GTP) levels revealed during regular checkup. CASE PRESENTATION: A 43-year-old man who had been working in a printing company with 15 years of exposure to organic solvents presented to our hospital owing to abnormalities found during a routine checkup. Ultrasound (US) imaging revealed thickening of the gallbladder wall accompanied by gallstones, although in the blood tests, γ-GTP levels were within normal range. Given the high risk of cholangiocarcinoma development, the patient underwent regular monitoring with abdominal US and blood tests at a local doctor's office. At the age of 48, his serum γ-GTP level mildly elevated for the first time, prompting the initiation of semi-annual magnetic resonance cholangiopancreatography (MRCP). By the age of 50 years, dilation in B8 was detected, and one and a half years later, a tumor on the central side of the B8 dilation appeared. The patient was diagnosed with intrahepatic cholangiocarcinoma, which was treated with anterior sectionectomy. Pathological examination revealed an adenocarcinoma with a papillary glandular ductal structure at the root of the B8. In addition, biliary intraepithelial neoplasia (BilIN) and dysplasia have been identified around the tumor and periphery bile ducts and in noncancerous bile ducts. Postoperatively, the patient received 6 months of adjuvant chemotherapy with S-1monotherapy. Eight months after surgery, the patient remained under observation with no signs of recurrence. CONCLUSIONS: We report a case of occupational cholangiocarcinoma detected during a prolonged period of regular follow-up after exposure to DCM and DCP. Given the delayed carcinogenesis process, occupational cholangiocarcinomas manifest long after exposure to organic solvents, therefore, ongoing screening is extremely important. Vigilance is essential to avoid underdiagnosis, particularly for individuals who are at an increased risk of developing this form of cancer. Continuous monitoring is key to the early detection and effective management of occupational cholangiocarcinoma.
RESUMO
BACKGROUND: The increasing incidence of gastric cancer in the elderly underscores the need for an in-depth understanding of the challenges and risks associated with surgical interventions in this demographic. This study aims to investigate the risk factors and prognostic indicators for non-cancer-related mortality following curative surgery in elderly gastric cancer patients. METHODS: This retrospective analysis examined 684 patients with pathological Stage I-III gastric cancer who underwent curative resection between January 2012 and December 2021. The study focused on patients aged 70 years and above, evaluating various clinical and pathological variables. Univariate analysis was utilized to identify potential risk factors with to non-cancer-related mortality and to access prognostic outcomes. RESULTS: Out of the initial 684 patients, 244 elderly patients were included in the analysis, with 33 succumbing to non-cancer-related causes. Univariate analysis identified advanced age (≥ 80 years), low body mass index (BMI) (< 18.5), high Charlson Comorbidity Index (CCI), and the presence of overall surgical complications as significant potential risk factors for non-cancer related mortality. These factors also correlated with poorer overall survival and prognosis. The most common cause of non-cancer-related deaths were respiratory issues and heart failure. CONCLUSION: In elderly gastric cancer patients, managing advanced age, low BMI, high CCI, and minimizing postoperative complications are essential for reducing non-cancer-related mortality following curative surgery.

Malignant peripheral nerve sheath tumours (MPNSTs) are malignant tumours arising from a peripheral nerve or displaying nerve sheath differentiation. Most MPNSTs are found on the head, body trunk and extremities, whereas cases in the gastrointestinal are extremely rare. About half arise in neurofibromatosis type 1 patients and 10% arise post-irradiation. This is probably the first small bowel MPNST post-radiation therapy case reported. A 72-year-old female who received radiotherapy 30 years ago for cervical cancer was admitted with progressive abdominal pain and weight loss. Computed tomography revealed a mass with inhomogeneous enhancement in the lumen of the small intestine. Tumour excision was performed with ileocecal and sigmoid colon resection due to suspicion for peripheral tissue invasion. Histopathological examination revealed spindle-shaped cells with focal cartilage differentiation. Together with immunochemistry stain showing complete loss of H3K27me3, a final diagnosis of MPNST was made. The patient is presently under regular follow-ups, and has remained disease-free for 24 months.
RESUMO
Intrahepatic splenosis (IHS) is a rare disease that is considered to result from heterotopic autotransplantation or implantation of splenic tissue after splenic trauma or surgery. A 46-year-old man with a treatment history of a left lateral liver segmentectomy and splenectomy for a road traffic injury 30 years earlier presented to Sakai City Medical Center (Sakai, Japan) with acute abdominal pain in November 2019. Physical examination showed no significant signs, and serum data were normal. Computed tomography revealed a hypodense mass measuring 2.5x1.7 cm in segment 7 of the liver. Gadoxetic acid-enhanced magnetic resonance imaging showed early enhancement in the arterial phase and washout in the delayed phase. Therefore, laparoscopic surgery was performed with a preoperative diagnosis of hepatocellular carcinoma. Pathological examination of the tumor showed IHS. The postoperative course was uneventful, and the patient developed no new abnormal region in the liver during 2 years of follow-up. The present study presented a case of IHS assumed to be hepatocellular carcinoma. IHS should be considered as a differential diagnosis of a liver mass detected years after splenic trauma or surgery, even in cases with imaging patterns suggesting malignancy.
RESUMO
BACKGROUND: Surgeons are often faced with optimal resection extent and reconstructive method problems in laparoscopic gastrectomy for gastric cancer in the upper and middle body of the stomach. Indocyanine green (ICG) marking and Billroth I (B-I) reconstruction were used to solve these problems with the organ retraction technique. CASE PRESENTATION: A 51-year-old man with upper gastrointestinal endoscopy revealed a 0-IIc lesion in the posterior wall of the upper and middle gastric body 4 cm from the esophagogastric junction. Clinical T1bN0M0 (clinical stage IA) was the preoperative diagnosis. Laparoscopic distal gastrectomy (LDG) and D1 + lymphadenectomy was decided to be performed considering postoperative gastric function preservation. The ICG fluorescence method was used to determine the accurate tumor location since the determination was expected to be difficult to the extent of optimal resection with intraoperative findings. By mobilizing and rotating the stomach, the tumor in the posterior wall was fixed in the lesser curvature, and as large a residual stomach as possible was secured in gastrectomy. Finally, delta anastomosis was performed after increasing gastric and duodenal mobility sufficiently. Operation time was 234 min and intraoperative blood loss was 5 ml. The patient was allowed to be discharged on postoperative day 6 without complications. CONCLUSION: The indication for LDG and B-I reconstruction can be expanded to cases where laparoscopic total gastrectomy or LDG and Roux-en-Y reconstruction has been selected for early-stage gastric cancer in the upper gastric body by combining preoperative ICG markings and gastric rotation method dissection.

A 51-year-old woman presented to our hospital complaining of a lower abdominal mass and dysuria. She was diagnosed with advanced sigmoid colon cancer. The tumor was large, involving the bladder, and occupying the pelvic cavity. She received neoadjuvant chemotherapy with 4 courses of mFOLFOX6, in addition to panitumumab. The treatment resulted in a marked reduction of the tumor. A laparoscopic sigmoid colon resection, total cystectomy, neobladder reconstruction, complete uterine and bilateral adnexa resection and partial ileal resection were performed. The histopathological diagnosis was ypT4b(bladder), ypN0, ypStage â ¡c, all with negative surgical margins. Adjuvant chemotherapy was not administered owing to the patient's refusal. She remained recurrence-free for 3 years of postoperative follow up.

A 68-year-old man was referred to our hospital because of back pain during swallowing. Upper gastrointestinal endoscopy revealed a lower esophageal type 3 tumor. The patient was diagnosed with esophageal squamous cell carcinoma by the biopsy specimen. CT scan showed thoracic lower esophagus wall thickening, left paracardiac lymph node swelling, and a low-density area in the liver. Therefore, the patient was diagnosed with Stage â £b esophageal cancer. After introducing cisplatin plus 5-FU combination therapy, the liver metastasis disappeared. After 9 chemotherapy courses, the patient received radical chemoradiotherapy. After completing chemoradiotherapy, the patient was followed up without any treatment. After 3 years since the treatment initiation, the patient is surviving without any relapse.

We present a case of a 72-year-old man diagnosed with rectal cancer invading the urinary bladder/prostate. Preoperative chemoradiotherapy substantially reduced the tumor size. In collaboration with urologists, robot-assisted low anterior resection with total cystectomy was performed using the da Vinci Xi system. Depending on the surgical situation, the colorectal surgeon and urologist could smoothly and rapidly play the role of a console surgeon. Although the first robot-assisted multi-organ resection of our institution, the surgery was completed safely without any complications. Although the patient developed urinary tract infection postoperatively, he recovered and was discharged after postoperative 23 days. In conclusion, robot-assisted surgery would be useful in pelvic surgery involving multiple departments such as colorectal surgery, urology, and gynecology.

We report a hepatocellular carcinoma(HCC)case with lung metastasis that was successfully treated with transarterial chemoembolization(TACE)and percutaneous radiofrequency ablation(RFA). A man in his 60s took right robe liver resection for HCC after TACE for its rupture. Lung metastasis occurred at S1+2 and S6 in the left lung, and an adverse event interrupted standard molecular target therapies. Because extrahepatic metastasis had been seen only in these two locations for a long time, TACE was performed for both metastases. The feeders for both lesions were each intercostal artery, and controlling the drug inflow was necessary to avoid drug influx into the spinal cord branches when S6 metastasis was treated. The viable lesion remained in the S6 lesion, so RFA was added for both lung metastases. 100% tumor necrosis has been observed since the RFA.

We herein reported a case of advanced gastric cancer (GC) with para-aortic lymph node (PALN) metastases who successful achieved downstaging following systemic chemotherapy and underwent curative laparoscopic conversion surgery. A 74-year-old male patient diagnosed with advanced GC and PALN metastases [cT4N3M1(LYM), stage IVA] was administered chemotherapy and immunotherapy for 28 months. After 27 courses of nivolumab as third-line chemotherapy, PALN enlargement was resolved, for which conversion surgery was planned. Subsequently, laparoscopic distal D2 gastrectomy with sampling para-aortic lymphadenectomy was performed, after which a pathological diagnosis of type V moderately differentiated tubular adenocarcinoma with mucinous adenocarcinoma, stage ypT3 (SS), ly1c, and v0, was established. The pathological proximal and distal tumor margins were negative. One lymph node metastasis was observed (No. 6; 1/25). The sampled lymph nodes were negative (No. 16a1: 0/2). The therapeutic effect was categorized as Grade 1a. The postoperative course was uneventful, with the patient receiving nivolumab to control for potential PALN metastases. Postoperatively, no recurrence was observed over 11 months. Laparoscopic conversion gastrectomy was successfully performed in a patient with advanced GC that was originally unresectable, suggesting that minimally invasive surgery may be a good option for originally unresectable advanced GC that becomes resectable.
RESUMO
Diaphragmatic resection may be required beneath the diaphragm in some patients with liver tumors. Laparoscopic diaphragmatic resection is technically difficult to secure in the surgical field and in suturing. We report a case of successful laparoscopic hepatectomy with diaphragmatic resection. A 48-year-old man who underwent laparoscopic partial hepatectomy for liver metastasis of rectal cancer 20 months ago underwent surgery because of a new hepatic lesion that invaded the diaphragm. The patient was placed in the left hemilateral decubitus position. The liver and diaphragm attachment areas were encircled using hanging tape. Liver resection preceded diaphragmatic resection with the hanging tape in place. Two snake retractors were used to secure the surgical field for the inflow of CO2 into the pleural space after diaphragmatic resection. The defective part of the diaphragm was repaired using continuous or interrupted sutures. Both ends of the suture were tied with an absorbable suture clip without ligation. In laparoscopic liver resection with diaphragmatic resection, the range of diaphragmatic resection can be minimized by performing liver resection using the hanging method before diaphragmatic resection. The surgical field can be secured using snake retractors. Suturing with an absorbable suture clip is conveniently feasible.

RESUMO
Although the standard treatment for intramucosal esophageal cancer without lymph node metastasis is endoscopic submucosal dissection (ESD), we sometimes encounter patients who are not able to undergo a transoral endoscopic examination. Here, we report a surgical procedure consisting of transgastric retrograde ESD to treat early esophageal cancer (T1a-EP, N0, M0) because of a stricture after hypopharyngeal cancer surgery. This retrograde ESD procedure can be a safe and effective treatment option for early esophageal cancer. This is the first report of a surgical retrograde ESD method for esophageal cancer.

Lenvatinib is reported to have a stronger angiogenesis-inhibiting effect in hepatocellular carcinoma(HCC)than sorafenib, but in many cases dose reduction and withdrawal are required due to the occurrence of adverse events. We report 12 cases of using lenvatinib for advanced HCC in our hospital together with a case of rapid re-growth due to withdrawal of lenvatinib. In 2 cases, metastases of HCC were controlled and radically resected. All patients required lenvatinib withdrawal due to Grade 3 adverse event, except for 2 cases that started with dose reduction. There were 3 cases in which drug withdrawal was required for 2 weeks or more, and in 2 of them, rapid re-growth of tumor was observed during the drug withdrawal and the treatment could not be continued. Although the use of lenvatinib may results in tumor shrinkage, suggesting that prolonged drug withdrawal may make disease management difficult. It is important to manage adverse events and minimize days of drug withdrawal by reducing the dose and systematically discontinuing the drug.

Here, we report a case of ascending colon cancer successfully treated with laparoscopic right hemicolectomy in a 74- year-old man with a medical history of hemophilia A. He was admitted to our hospital because of bloody stool and diagnosed with type 2 ascending colon cancer based on colonoscopy findings. Preoperatively, blood transfusion and administration of recombinant factor â § products were performed. Surgery involved laparoscopic right hemicolectomy plus group 3 lymph node dissection. No complications, such as bleeding, occurred during hospitalization. The patient was discharged on postoperative day 8. There have been a few reports of laparoscopic surgery for patients with hemophilia. However, this case suggests that it can be safely performed with planned factor â § supplementation in the perioperative period.

PURPOSE: Pelvic exenteration (PE) for locally advanced or recurrent colorectal cancer is often used to secure negative resection margins. The aim of this study was to evaluate the feasibility of laparoscopic PE. MATERIALS AND METHODS: The clinical records of 24 patients (9, open; 15, laparoscopic) who underwent total or posterior PE for locally advanced or recurrent colorectal cancer between July 2012 and April 2016 at Osaka National Hospital were retrospectively reviewed. Operative factors were compared between the 2 groups. RESULTS: The R0 resection rate was 100% in the laparoscopic group and 89% in the open group. The operative time and the incidence of postoperative complications were not significantly different between the 2 groups. The laparoscopic group showed less intraoperative blood loss (P=0.019), a lower C-reactive protein elevation on postoperative day 7 (P=0.025), and a shorter postoperative hospital stay (P=0.0009). CONCLUSIONS: Laparoscopic PE is a safe and feasible procedure to reduce postoperative stress.

We report a case of recurrent pancreatic cancer in the remnant pancreas after pancreatoduodenectomy(PD)that was successfully treated by surgical resection. A woman in her 70s who was treated for multiple lung metastases of breast cancer was referred to our hospital because of obstructive jaundice. A low-density area in the pancreas head(19mm in diameter) and dilatation of the main pancreatic duct were observed on abdominal CT. She was diagnosed with pancreatic head cancer and underwent PD. Twenty months after PD, abdominal CT revealed a tumor in the pancreas tail, and she started receiving chemotherapy containing gemcitabine(GEM)for the diagnosis of recurrent pancreatic cancer in the remnant pancreas. Twelve months after the induction of chemotherapy, we performed surgical resection of the tumor(total pancreatectomy). The pathological diagnosis was moderately differentiated adenocarcinoma, which was similar to the primary lesion, and the tumor was confirmed as recurrence of pancreatic cancer. Although she died of multiple lung metastases of breast cancer 62 months after the total pancreatectomy, the recurrence of pancreatic cancer was not observed without adjuvant therapy during that time.

No large clinical trials have been conducted to prove the efficacy of peritoneal dissemination resection for colorectal cancer, and no evidence has shown the usefulness of resection for metachronous peritoneal dissemination. An elderly woman in her 70s underwent a laparoscopic transverse colectomy for transverse colon cancer in 2014, which was performed by another physician. The pathological diagnosis was tub2-por>muc, pT3, ly2, v0, pN2, and pStage â ¢b. The patient was followed up with capecitabine plus oxaliplatin(CapeOX)therapy as an adjuvant chemotherapy for 6 months. Three years postoperatively, the CEA level increased to 10 ng/mL, and CT showed a nodular shadow in front of the left prerenal fascia. After the diagnosis of peritoneal dissemination recurrence and 8 courses of capecitabine plus bevacizumab therapy, other metastases were not observed. She was referred to our hospital for surgery and underwent laparoscopic peritoneal dissection at 3 years and 6 months after the first operation. Only one apparent disseminated recurrent lesion, which was resectable, was observed. However, at 4 years and 9 months after the initial operation, CT showed a recurrence of Douglas pouch peritoneal dissemination without any other obvious metastasis. Laparoscopic low anterior resection of the rectum and hysterectomy were performed. Here, we encountered a case that could be radically resected for peritoneal dissemination twice after the colon cancer surgery.
