RESUMEN
BACKGROUND: Robotic gastrectomy(RG)for gastric cancer(GC)has been covered by health insurance since 2018. In this study, we examined the results of RG for GC at our hospital during the initial period of its introduction. MATERIALS AND METHOD: From August 2022 to May 2023, we retrospectively examined the surgical outcomes and short-term postoperative outcomes of the first 9 patients who underwent RG for GC at our hospital. RESULTS: The median patient age was 77(67-82) years, gender was 4 males and 5 females, and distal gastrectomy was performed in all patients. The median operative time was 410(323-486)min, blood loss was 5(1-140)mL, postoperative hospital stay was less than 9 days in all patients, and there was no conversion to laparoscopic or open surgery. There were no postoperative complications of Clavien-Dindo Grade â ¡ or above. CONCLUSION: In this study, RG for GC was performed safely without intraoperative or postoperative complications.

Endoscopic resection is typically performed for early T1 stage colorectal cancer (T1 CRC). Additional surgery is subsequently recommended based on pathological findings; however, the current criteria may result in overtreatment. The present study aimed to re-examine the reported risk factors for lymph node (LN) metastasis in T1 CRC and develop a prediction model using a large multi-institutional dataset. In this retrospective study, the medical records of 1,185 patients with T1 CRC who underwent surgery between January 2008 and December 2020 were investigated. Slides pathologically re-assessable for additional risk factors were re-examined. A total of 251 patients with inadequate data were excluded, and 934 patients were randomly assigned at a ratio of 3:1 to the training and validation datasets. In the univariate analysis, left-sided CRC (P=0.003), deep submucosal invasion depth (P=0.005), poor histological grade (P=0.020), lymphatic invasion (P<0.001), venous invasion (P<0.001) and tumor budding grade 2/3 (P<0.001) were significant risk factors for LN metastasis. A nomogram predicting LN metastasis was developed using these variables, with an area under the received operating characteristic curve (AUC) of 0.786. The nomogram was validated using a validation set with an AUC of 0.721, indicating moderate accuracy. No LN metastases were observed in patients with <90 points using the nomogram; therefore, patients with a low nomogram score may avoid undergoing surgical resection. Prediction of LN metastasis using this developed nomogram may help identify patients who are at high-risk who require surgery.
RESUMEN
We report a case of colon metastasis from gastric cancer treated by laparoscopic-assisted segmental colectomy. An 81-year-old man was undergone distal gastrectomy, D2 dissection and Billroth â reconstruction for gastric cancer 3 years previously, with a final diagnosis of gastric cancer L, Post, Type 2, sig/por2, pT4a(SE), pN3b(30/56), H0, P0, M0, pStage â ¢C. Three years after gastrectomy, CT scan showed an elevated lesion in the transverse colon, which was suspected to be metastatic colorectal cancer on closer examination. As no metastatic lesions were found other than the tumor of transverse colon, we performed laparoscopic-assisted segmental colon resection. A small incision was placed in the umbilical region, and the transverse colon was extracted from the umbilical region after dissection of the adhesions by single-incision laparoscopic surgery. The transverse colon containing the mass lesion was partially resected extracorporeally and reconstructed with a functional end-to-end anastomosis. The postoperative pathological findings revealed tumor cells predominantly below the submucosal layer and partly showing the signet ring cell carcinoma, and the transvers colon tumor was diagnosed as a metastasis from gastric cancer. The postoperative course was uneventful and the patient was discharged 8 days after surgery, and is alive for 10 months after the segmental colon resection followed by chemotherapy.

We report a case of recurrent esophageal cancer with long-term survival treated by S-1 monotherapy. A 66-year-old man underwent subtotal esophagectomy, two-field lymphadenectomy after 2 courses of DCF chemotherapy for esophageal cancer 1 year earlier. The final diagnosis was esophageal cancer, Lt, CT-Type 2, ypT3, ypN0(0/62), M0, ypStage â ¢. At 6 months after esophagectomy, CT scan revealed mediastinal lymph node metastasis and pleural dissemination, and paclitaxel monotherapy was performed, but lymph node re-enlargement was observed on CT at 12 months after esophagectomy. Chemotherapy with S-1 monotherapy was performed, and 3 months after initiation of S-1 monotherapy, CT showed reduced lymph node metastases and pleural dissemination remained reduced. Adverse events were CTCAE v5.0 Grade 2 thrombocytopenia and diarrhoea, but no Grade 3 or higher adverse events were observed. Long-term survival was achieved with no disease progression for more than 2.5 years after initiation of S-1 monotherapy.

Here we report the case of a patient with advanced gastric cancer who presented with duodenal intramural metastasis based on the pathological results after surgery. The patient was 78-year-old female, who was referred to our department for further evaluation and treatment of upper abdominal pain. An upper gastrointestinal series demonstrated a tumor occupying the lesser curvature of the gastric body. Biopsy specimens from the tumor demonstrated moderately to poorly differentiated adenocarcinoma. A computed tomography scan showed thickening of the gastric wall and swelling of the regional lymph nodes. The patient underwent distal gastrectomy and D2 lymph node dissection for gastric cancer. A histopathological examination disclosed that the gastric tumor was poorly differentiated adenocarcinoma with severe lymphatic permeation and also demonstrated the other poorly differentiated adenocarcinoma occupying the part of the muscularis propria layer of the duodenum. The gastric tumor was not contiguous with the duodenal tumor, and the duodenal cancer cells had the same pathological characteristics as the primary gastric cancer cells; therefore, we diagnosed the duodenal tumor as an intramural metastasis from gastric cancer. The patient's disease was staged as pT4aN3bM1, Stage â £ according to the TNM classification. We report this rare case along with a discussion of the literature.

A 50-year-old man presented with fecaluria and was diagnosed with sigmoid colon cancer with a colovesical fistula. Total bladder resection was determined to be necessary for curative resection at the time of diagnosis. In anticipation of bladder preservation, 6 courses of mFOLFOX6 plus panitumumab were administered after transverse colostomy, resulting in marked tumor regression and a decision to proceed with surgery. The patient underwent robotic-assisted low anterior resection of the rectum and partial cystectomy, which yielded pathological radical treatment. We report a case of sigmoid colon cancer with a colovesical fistula complicated by bladder invasion, in which preoperative chemotherapy was effective and total cystectomy was avoided, allowing bladder preservation.

BACKGROUND: We analyzed the short-term outcomes and nutritional assessment of gastric cancer surgery patients who underwent exercise intervention after gastrectomy. MATERIALS AND METHOD: Gastric cancer patients who underwent gastrectomy at our department from January 2021 were included in the study. Postoperative exercise intervention(lower limb training) was performed in gastric cancer patients aged 75 years or older(group H: 7 patients)and compared retrospectively with gastric cancer patients younger than 75 years(group L: 10 patients)who did not receive exercise intervention. The rate of decrease in each index after 1 week was compared between the 2 groups. RESULTS: Postoperative complications(yes/no) were 3/4(42.8%)in group H and 2/8(20.0%)in group L(p=0.59); postoperative hospital stay was 11.5(10.8-21.3) days in group H and 11.0(9.0-14.0)days in group L(p=0.37). The percentage decrease in each index was as follows: for BMI in groups H/L: 2.9/5.6%(p=0.17), grip strength in groups H/L: 2.4/ï¼7.6%(p=0.07), skeletal muscle mass in groups H/L: ï¼2.3/7.0%(p=1.00), PNI in groups H/L: 26.6/18.1%(p=0.12). CONCLUSION: In this study, no significant differences were noted in postoperative complication rates or postoperative hospital stay between groups H and L.

Situs inversus totalis(SIT)is a rare congenital condition that causes complete transposition of thoracic and abdominal viscera. Due to associated anatomical abnormalities and low frequency, surgery for affected patients is considered to be difficult. A 72-year-old man was referred to our hospital with a chief complaint of narrow stools. The diagnosis was anal canal cancer(cT1bN0M0)accompanied by SIT. A trans-perineal minimally invasive surgical procedure with laparoscopic abdominoperineal resection(Tp-APR)was performed. When mobilizing the sigmoid colon, the surgeon changed their position in consideration of anatomical abnormalities. On the other hand, manipulation around the rectum was possible using the same technique as in patients with normal anatomy. The postoperative course was uneventful, and he had no recurrence 18 months after surgery. This is the first case that showed Tp-APR for anal canal cancer with SIT performed safely and feasibly. Preoperative simulation of associated abnormal anatomical structures is considered crucial for a case of SIT.

LESSONS LEARNED: The 3-year disease-free survival rate of the twice-daily regimen was not inferior to that of the conventional three-times-daily regimen, and the twice-daily regimen did not lead to an increase in adverse events. The effectiveness of the twice-daily regimen highlights an increased number of treatment options for patients. This will facilitate personalized medicine, particularly for elderly or frail patients who may experience more severe side effects from the combination therapy. BACKGROUND: Tegafur-uracil (UFT)/leucovorin calcium (LV) is an adjuvant chemotherapy treatment for colorectal cancer. We conducted a multicenter randomized trial to assess the noninferiority of a twice-daily compared with a three-times-daily UFT/LV regimen for stage II/III colorectal cancer in an adjuvant setting. METHODS: Patients were randomly assigned to group A (three doses of UFT [300 mg/m2 per day]/LV [75 mg per day]) or B (two doses of UFT [300 mg/m2 per day]/LV [50 mg per day]). The primary endpoint was 3-year disease-free survival. RESULTS: In total, 386 patients were enrolled between July 28, 2011, and September 27, 2013. The 3-year disease-free survival rates of group A (n = 194) and B (n = 192) were 79.4% and 81.4% (95% confidence interval, 72.6-84.4-74.5-85.9), respectively. The most common grade 3/4 adverse events in group A and B were diarrhea (3.9% vs. 7.3%), neutropenia (2.9% vs. 1.6%), increase in aspartate aminotransferase (4.0% vs. 3.9%), increase in alanine aminotransferase (6.2% vs. 6.8%), nausea (1.7% vs. 3.4%), and fatigue (1.1% vs. 2.3%). CONCLUSION: Group B outcomes were not inferior to group A outcomes, and adverse events did not increase.

This study reports a 66-year-old female presenting abdominal pain. Gastrointestinal endoscopy showed the presence of a type 3 tumor in the lesser curvature of the stomach, and biopsy revealed poorly differentiated adenocarcinoma. CT images displayed thickening of the stomach wall and enlarged paraaortic lymph nodes, left supraclavicular lymph nodes, and left iliac lymph nodes. FDG-PET/CT scan showed abnormal accumulation at the same site. The patient was diagnosed with unresectable highly advanced gastric cancer(cT4aN2H0P0M1[LYM], Stage â £). She was treated with combination chemotherapy of S-1 and CDDP(SP). Tumor markers normalized(CA19-9 11,158â20 U/mL)after 3 courses with a marked reduction of lesions. After 5 courses of chemotherapy, the tissue biopsy did not reveal any cancer and a complete response(CR) was achieved. Adverse events of diarrhea and loss of appetite were observed. Subsequently, chemotherapy was discontinued after 6 courses, and CR remained for the next 5 years. Thus, we experienced a rare case of unresectable advanced gastric cancer with distant lymph nodes metastasis, showing long-term recurrence-free survival after receiving 6 courses of SP chemotherapy.

A 75-year-old man underwent laparoscopic ileocecal and partial small bowel resections for the management of appendiceal cancer. The pathological diagnosis was cecal cancer(T4b[ileum, abdominal wall],N0[0/13], M0, pStage â ¡c). After 4 months of surgery, he suddenly experienced abdominal pain and vomiting and was presented to our emergency room. He was diagnosed with bowel obstruction following which, conservative treatment was initiated through a nasogastric ileus tube implantation; however, he did not show any improvement. Subsequently, he underwent experimental laparotomy on the 18th day of the disease. Intraabdominal examination revealed herniated small intestine through a mesenteric defect, which was closed following repositioning of the herniated small intestine. The postoperative course was good, and the patient was discharged on the 10th day after surgery. No recurrence of intestinal obstruction has been observed after 1 year and 6 months. Closure of the mesenteric defect, although not commonly performed in laparoscopic colorectal surgery, is worth considering because of the risk of developing an internal hernia requiring surgical treatment, as in our case.

A 67-year-old woman reporting lower abdominal pain and anemia was examined. Small intestinal tumor was diagnosed by small intestinal radiographic contrast study and small intestinal endoscopy, and we decided to perform a laparoscopic partial resection of the small bowel. Since she was obese patients(BMI 36.3, abdominal wall 6 cm)at high risk of postoperative incisional hernia, we devised a way to make the wound smaller. We judged thick abdominal wall make umbilical wound larger in single port surgery. We performed multi-port surgery by using one 15 mm trocar, and removed small intestinal tumor from 15 mm port incision. In addition, to prevent incisional hernia, we used a trocar with a wound closure assist function for securely closing the port wound in all layers. Histopathological diagnosis was neuroendocrine tumor. The patient is being followed up without recurrence and without incisional hernia. In partial small bowel resection of obese patient, the use of a 15 mm port to minimize wound site and the use of trocar with a wound closure assist function may lead to prevent incisional hernia.

A 59-year-old man visited our department because of cholecystectomy. Preoperative CT revealed a tumor shadow measuring 50 mm in front of the right iliopsoas muscle. MRI showed a low signal intensity on T1-weighted images and a slightly high signal intensity on the T2-weighted image. PET-CT showed accumulation of FDG(SUVmax 5.39)in the tumor but no other abnormal accumulations. We performed tumor resection for diagnostic purposes because malignancy could not be ruled out owing to the large size of the mass. Intraoperative findings showed a well-circumscribed margin of the tumor without invasion to other tissues. The retroperitoneum was incised circumferentially along the tumor under laparoscopic guidance, and the tumor was resected. Histopathological and immunostaining findings were consistent with leiomyosarcoma. In laparoscopic surgery, the surgical margin is observed in detail through the magnifying effect. Therefore, laparoscopic surgery can be a surgical option for tumors that may be completely excised based on preoperative findings.

The patient is 77-year-old man. He received open cholecystectomy and choledocholithotomy when he was 74 years old. Because postoperative diagnosis was small cell neuroendocrine carcinoma(NEC), the resection of gallbladder bed and hilus lymph nodes were performed. During the follow up period, the liver metastases and portal vein tumor thrombosis appeared. Therefore, chemotherapy was performed according to small cell lung cancer. In addition to chemotherapy, radiation therapy was performed for the purpose of local control. He is still alive about 3 years after the first operation. This case suggested the efficacy of multidisciplinary treatment including operation, chemotherapy, and radiation therapy in NEC of gallbladder patient with liver metastasis.

The patient was a 73-year-old man, diagnosed as advanced gastric cancer with para-aortic lymph nodes(PAN)metastasis. He was treated by 3 courses of neoadjuvant chemotherapy(NAC)with S-1 and oxaliplatin(SOX therapy). CT showed significant reduction of both primary tumor and metastatic lymph nodes. We performed distal gastrectomy with D2 plus PAN dissection. The histopathological findings showed no residual viable tumor cell. The pathological effect of chemotherapy was judged Grade 3(pCR)in both primary tumor and dissected lymph nodes. He is alive without recurrence 21 months after surgery.

We report a rare case of hepatic fibrolamellar hepatocellular carcinoma(FLC). A 25-year-old Vietnamese male experienced loss of appetite and abdominal pain. He was referred for further examination of a 20 cm tumor in the left lobe of the liver detected in mass screening ultrasonography. He tested negative for HBs-antigen and HCV-antibody. The serum PIVKA- â ¡ level was elevated. Liver function test findings were normal. The arterial phase of contrast enhanced abdominal CT revealed a 20×30 cm tumor that was well-enhanced, except for a central scar in the left lobe of liver. Enhanced MRI showed a high intensity tumor. T2-weighted MRI showed an iso-intensity tumor with a low-intensity central fibrous scar. Upon diagnosing the patient with FLC, we performed left hepatic trisegmentectomy. Pathological findings of the surgical specimen showed eosinophilic large neoplastic cells surrounded by fibrous stroma arranged in a lamellar fashion. This confirmed the diagnosis. FLC, which occurs in noncirrhotic livers of young patients, is a distinct clinicopathological variant of hepatocellular carcinoma. Hepatectomy for FLC should be accompanied with regional lymphadenectomy because of its association with lymph node metastasis. We also reviewed cases reported in Japan.

A 72-year-old woman was transferred to our hospital after being diagnosed with retroperitoneal and ovarian tumors. Abdominal computed tomography revealed a well-defined mass lesion measuring 35 mm on the dorsal side of the descending part of the duodenum that was surrounded by the head of the pancreas and inferior vena cava. In addition, a cystic mass measuring 90 mm was found in the pelvis. Hence, the patient was diagnosed synchronous retroperitoneal tumor and teratoma. Laparoscopic retroperitoneal tumor resection and right adnexectomy were performed. The pathological findings indicated that the retroperitoneal tumor was a diffuse large B-cell lymphoma and the pelvic tumor was a mature cystic teratoma of the ovary. On the basis of the computed tomography findings, we judged that the tumor had a poor tendency to infiltrate and could be peeled off and resected using laparoscopic surgery. In this rare case, the retroperitoneal tumor and mature teratocarcinoma were simultaneously resected laparoscopically.

We report a patient who had Castleman's disease with lymphadenopathy during the treatment of gastric cancer. In May 2017, a 63-year-old man underwent gastrointestinal endoscopy, which revealed a tumor on the posterior wall of the lower part of the stomach. Based on a biopsy, he was diagnosed with suspected adenocarcinoma, Group 4. In June 2017, he visited our hospital, and endoscopic submucosal dissection(ESD)was performed. The pathological diagnosis of the resected specimens was L, Less, 20×10 mm, Type 0-â ¡c, tub1, pT1a(M), UL(-), ly(-), v(-), pHM0, pVM0, pStage â A. He was referred to our department for the treatment of abdominal lymphadenopathy. His lymphadenopathy was localized in the gastric lesser curvature as an enlarged lymph node 15mm in size, based on the findings of contrast-enhanced CT. On FDG- PET/CT, we found a slight accumulation of SUVmax 2.4 in the early phase in the same lymph node. We could not confirm a diagnosis, and we performed laparoscopic dissection of the lymph node for diagnosis and treatment. The size of the specimen was 14×14mm, surface was smooth, and lymph node was elastic and soft. We found lymphoid follicles with atrophic germinal center using HE staining. We also found increased hyperplastic blood vessels around the germinal center, and he was diagnosed with hypervascular Castleman's disease.

A 66-year-old man underwent total gastrectomy for gastric cancer. S-1 was administered as adjuvant chemotherapy. Abdominal CT showed para-aortic lymph node recurrence 31 months after the surgery. There was no other recurrence according to PET-CT, and we performed para-aortic lymph nodes dissection 41 months after the surgery. Lymph node recurrence in the retrocrural space was observed 37 months after the 2nd surgery. We administered S-1 plus L-OHP chemotherapy. After 4 courses, CT revealed that he had achieved complete response, and he has remained disease-free for 79 months after lymph node dissection. Some patients with para-aortic lymph node recurrence after curative gastrectomy may benefit from treatment including chemotherapy and surgical dissection.
