Background Totally extraperitoneal (TEP) repair is a recommended procedure for inguinal hernia repair in European hernia guidelines. However, technical challenges have limited its uptake in Japan, where transabdominal preperitoneal (TAPP) repair is more common. We evaluated the association of preoperative subcutaneous fat area (preSFA) with surgical outcomes and identified factors associated with the difficulty of TEP repair.Methods Clinical data from 62 patients undergoing TEP repair were collected retrospectively. Using the median for the preoperative subcutaneous fat index (preSFI; 45.9 cm

Background: The short- and long-term results from several reports suggest that laparoscopic surgery (LAP) for elderly patients is expected to reduce the risk of complications due to its minimal invasiveness, However, little is known about the effect of LAP on long-term prognosis aside from cancer. Patients and Methods: Eighty-five cases over 80 years old with colorectal cancer whose primary lesions were resected consecutively were enrolled. Risk factors for complications were searched using categorized clinicopathological factors. The factors for death unrelated to cancer were analyzed in patients by excluding cancer-related death. Results: Incidence of all complications, those of Clavien–Dindo grade 2 or more, and surgical site infection were significantly lower in LAP-treated patients (p=0.0343, p=0.0015 and p=0.0015, respectively). By multivariate analysis, LAP (odds ratio=0.19, 95% confidence intervaI=0.05-0.75, p=0.0177) and no pulmonary dysfunction (odds ratio=0.24, 95% confidence intervaI=0.06-0.96, p=0.0441) were significantly associated with reduced risk of complications of Clavien–Dindo grade 2 or more. LAP, no pulmonary dysfunction and Eastern Cooperative Oncology Group performance status of 0 or 1 were also significantly associated with reduced risk for death from non cancer-related causes. Additionally, LAP was significantly associated with improved survival excluding cancer-related death in patients with pulmonary dysfunction (p=0.0020) or with poor performance status (p=0.0412). Conclusion: These results suggest that fewer complications and non cancer-related deaths were achieved in very elderly patients with colorectal cancer when treated by LAP.

The patient was a 72-year-old man with a chief complaint of abdominal pain. We performed laparoscopic left hemicolectomy of the colon after descending colon cancer ileus stenting, and postoperative pathology was pT4aN0M0, pStage Ⅱb. In 1.5 years postoperatively, 2 liver metastases and 1 lymph node metastasis were found, and each was resected. Chemotherapy was initiated for multiple lung metastases. Genetic testing was positive for BRAF V600E mutation, and the patient received 8 mFOLFOXIRI plus bevacizumab therapy courses. After 15 5-FU plus LV plus bevacizumab courses, the patient had a brain infarction and lung metastasis reincreased. Chemotherapy was changed to encorafenib plus binimetinib plus cetuximab. On day 2, visual impairment was observed, and serous retinal detachment CTCAE Grade 2 was diagnosed. On day 7, the symptoms improved and one-step dose reduction was resumed. On day 2 of re-treatment, serous retinal detachment recurred and treatment was discontinued. On day 4 of re-treatment, the symptoms improved, another dose reduction was performed, and treatment was resumed. Since subjective MEK inhibitor-induced ocular symptoms are often minor, conducting an interview and early ophthalmologic diagnosis is recommended.

Introduction Because splenic metastasis from colorectal cancer is usually a result of metastasis from widely disseminated disease, cases with resectable isolated splenic metastasis are uncommon. Case presentation We report here a case of synchronous isolated splenic metastasis from cecal cancer that was treated with sequential laparoscopic splenectomy after short-term observation following laparoscopic ileocecal resection. Both postoperative courses were uneventful, allowing the patient to be discharged early. Two years have passed, without recurrence, since the second operation. Conclusions There are very few case reports on synchronous isolated splenic metastasis from colorectal cancer. Sequential laparoscopic resection might contribute to obtaining an uneventful postoperative course, especially in elderly patients such as ours.

We report 4 cases of liver metastasis from renal cell carcinoma(RCC). Case 1: 72 years old, female. Pancreatic metastasis was resected 7 years after resection of left RCC, and hepatic posterior sectionectomy was performed for multiple liver metastases 2 years later. After that, multi-organ metastasis appeared and she died of the primary disease. Case 2: 72 years old, male. Liver metastasis and right RCC appeared 16 years after resection of left RCC, and hepatic posterior sectionectomy and partial resection of right kidney were performed. Nine months later, liver metastasis recurred and hepatic partial resection was performed. Case 3: 55 years old, male. After surgery for right RCC with tumor thrombus in the right atrium, multiple lung and liver metastases appeared, and hepatic central bisectionectomy was performed after chemotherapy. Case 4: 60 years old, male. Multiple pancreatic and lung metastases appeared 10 years after resection of left RCC, and most of them shrank or disappeared with chemotherapy. But increasing metastases appeared in the tail of pancreas and the right lobe of liver 16 months later, and hepatic subsegmentectomy and distal pancreatectomy were performed. Multidisciplinary treatment such as aggressive chemotherapy and excision is expected to improve the prognosis for liver metastasis from RCC.

We investigated the significance of transitions in the neutrophil-to-lymphocyte ratio(NLR)before and after TACE for HCC could be a predictor of prognosis. The subjects were 108 patients with the first TACE performed from January 2010 to December 2019. NLR was calculated before and 1 month after TACE, and the relationship with therapeutic effect and prognosis was examined. When the transition of NLR before and after TACE was classified into 3 groups with a cut-off value of 5.0, group A(less than 5.0 after TACE): 52 cases(48.1%), group B(5.0 or more after TACE): 33 cases(30.6%)and C group(5.0 or more before and after TACE): 23 cases(21.3%). Median survival time were 25.0 months in group A, 18.5 months in group B, and 12.7 months in group C(p=0.0005). In multivariate analysis, treatment effect, NLR transition, AFP value, and serum albumin level were prognostic factors for HCC after TACE. Changes in NLR before and after TACE may help predict more detailed prognosis.

The patient was a 65-year-old man for whom a right hemicolectomy was performed for transverse colon cancer and multiple lymph node metastases. Peritoneal dissemination was observed throughout the abdominal cavity, and curative resection was not possible. Postoperative diagnosis: pT4bN2M1c(P3), Stage Ⅳc, and mutant RAS status. Therapy consisting of mFOLFOX6 plus bevacizumab was started 1 month after surgery, and up to 25 courses were completed. FOLFIRI plus bevacizumab therapy was performed up to 13 courses as the second-line therapy. Regorafenib 80 mg/day was started as the third-line therapy and the dose was gradually increased. It was performed up to 14 courses for about 13 months, without major adverse events, to keep the disease stable or slow its progression. Although up to 5 courses of FTD/TPI plus bevacizumab therapy were delivered as the fourth-line therapy, he died of disease progression. Regorafenib, which has been approved as a salvage line for metastatic colorectal cancer, features many adverse events, and there are few cases in which the approved dose can be administered. In our case, starting at a low dose resulted in fewer adverse events, adequate disease control, and long-term administration.

We hereby report a case of advanced and recurrent colon cancer with long-term survival after 7 repeated surgical resections. A 73-year-old woman initially underwent right hemicolectomy and partial hepatectomy for an ascending colon cancer with synchronous liver metastasis. Pathological diagnosis of the tumors were moderately differentiated adenocarcinoma and metastasis to the liver compatibly. Final clinical stage was diagnosed as fT3N2M1(H1), fStage Ⅳ. But she was interrupted oxaliplatin-based adjuvant chemotherapy after 6 courses of CAPOX because of adverse drug reaction. One year after first operation, partial resection of right lung was performed for lung metastasis. Two years after first operation, 2nd resection of liver was performed for 2 liver metastatic lesions. Three years after first operation, 3rd partial liver resection, 2nd and 3rd partial lung resections were performed for metachronous metastases during 1 year. After 3 years recurrence free period, she complained of an induration of right neck and diagnosed as neck and supra clavicular lymph nodes metastases. Lymph nodes resection was performed. After the last operation, she has no sign of cancer recurrence for 1 year and 7 months, eventually she has been alive for 7 years and 7 months after the initial operation.

Incidence of infusion related reaction (IR) is more common with cetuximab (Cmab) than with panitumumab (Pmab). Although little is known about rechallenge IR with monoclonal antibodies, we experienced a successful rechallenge to Cmab after IR to Pmab. A 67-year-old female patient was scheduled for chemotherapy with mFOLFOX6 plus Pmab against unresectable advanced rectal cancer in the hope of tumor shrinkage. On the first administration of Pmab, she complained of dyspnea with shortness of breath and wheezing, even after premedication with steroids and antihistamines. Her reaction was judged as Grade 2 IR to Pmab. For the next course, we tried Cmab. No IRs were observed. Since then, she has undergone seven further courses of treatment, followed by surgical resection. The patient benefited from administration of Cmab after experiencing IR to Pmab, suggesting this treatment to be an option for patients of this type who experience IR to Pmab.

The efficacy of laparoscopic surgery for elderly patients aged over 80 years who have colorectal cancer was investigated concerning complications. Sixty-five patients over 80 years old who underwent colorectal cancer resection until January 2018 were enrolled. Factors that led to complication were analyzed retrospectively. Thirty-three men and 32 women were included, with a median age of 83 years. Forty-eight cases were located at the colon; and 17, at the rectum. The median operating time was 164 minutes, including 39 cases treated with the laparoscopic approach. Postoperative complications were observed in 28 cases(43.1%), of which 15(23.1%)had a Clavien-Dindo(CD)classification of Grade BⅡ. These cases had significantly prolonged postoperative hospital stay. Complications included 10 cases of incisional surgical site infection(SSI), 9 cases of ileus, 6 cases of melena, 2 cases of urinary infection, 2 cases of urinary disorder, and 1 case of postoperative death. Open surgery was the only significant factor associated with the incidence of CD classification of BⅡ(p=0.0330). Among the complications, the incisional SSI was reduced by laparoscopic surgery(p=0.0050). The number of laparoscopic surgeries reduced the incidence of CD classification BⅡ of complications in elderly patients aged over 80 years who had with colorectal cancer resection. The use of incisional SSI also decreased with the use of laparoscopic surgery. Laparoscopic surgery for colorectal cancer in elderly patients may lead to reduced complication rates.

BACKGROUND/AIM Pancreaticoduodenectomy (PD) treatment outcomes in elderly patients have been reported to be acceptable, but the eligibility criteria are not clear. To elucidate the importance of PD in octogenarians in particular, we set five eligibility criteria for elderly patients based on preoperative cardiac and pulmonary function, nutritional status, daily activity status, and psychological independence status for the first time and evaluated prospectively whether the validity of patient selection was adaptable. PATIENTS AND METHODS The study population consisted of 222 patients with pancreaticobiliary cancer aged over 70 years. The patients were divided into two groups: 192 patients as septuagenarians and 30 as octogenarians. Postoperative morbidity and long-term outcome were compared between the two groups, and prognostic factors relating to survival time were identified. RESULTS Octogenarians had a significantly higher frequency of two or more comorbidities (p

Pancreaticoduodenectomy(PD)treatment outcomes in elderly patients have been reported to be acceptable, but the eligibility criteria are not clear. To elucidate the importance of PD in octogenarians, we set beforehand the eligibility criteria in the elderly and evaluated whether the validity of the patient selection was adaptable.The study population consisted of 244 patients aged70 years who hadpancreaticobiliary cancer. The patients were divided into 2 groups as follows: 32 patients in the octogenarian group and 212 patients in the septuagenarian group. The eligibility criteria were as follows: (1)cardiac function as ejection fraction of at least 40%, measured using Doppler echocardiography; (2)pulmonary function as forcedexpiratory volume in 1 second(FEV1.0%)of at least 50%on spirography; (3) nutritional status as serum albumin level of at least 3.0 g/dL; (4)daily activity status as Karnofsky performance status of at least 80%; and(5)psychological independence status as the capability of self-determination with respect to surgery. Postoperative morbidity and long-term outcome were comparedbetween the 2 groups, andprognostic factors relating to survival time were identified.The patients in the octogenarian group showed a significantly higher incidence rates of 2 or more comorbidities(p0.0001)andd elirium(p=0.024). The difference in mortality rate between the 2 groups was not significant. No significant difference in overall survival rate was found between the 2 groups(p=0.197). The independent prognostic factors relating to survival duration were intraoperative blood loss(p=0.0008)andd uration of surgery(p= 0.0091).The eligibility criteria for PD in elderly patients are also satisfactorily applicable to octogenarian patients. These criteria may be helpful when uncertainties arise regarding the selection of PD.

A 77-year-old woman with back and epigastric pains was diagnosed with pancreatic head cancer according to the result of contrast computed tomography, which showed a 25mm irregular low-density area at the pancreatic head infiltrating nearly half of the superior mesenteric plexus. There were no findings of lymph node metastasis or distant metastasis. The pretreatment diagnosis was borderline resectable(BR)pancreatic head cancer, cT3, N0, M0, cStage ⅡA. The patient was treated with gemcitabine plus nab-paclitaxel therapy. She developed Grade 3 neutropenia, and the dose was adjusted in order to continue chemotherapy. The size of the tumor had reduced to 15mm after 6 courses of the therapy, and the infiltration into the superior mesenteric plexus had also reduced. Therefore, the patient underwent subtotal stomach-preserving pancreatoduodenectomy and D2 lymph node dissection. The histopathological findings were invasive ductal carcinoma with R0 radical resection. The efficacy of preoperative adjuvant chemotherapy for BR pancreatic cancer has not been established yet, but improving the R0 resection rate with preoperative chemotherapy may contribute to an improvement in the outcome of pancreatic cancer.

Background and Aim: The recommendedind ication of transcatheter arterial chemoembolization(TACE)for hepatocellular carcinoma(HCC)is Barcelona Clinic Liver Cancer(BCLC)stage B HCC. But there are some cases in which we do not perform TACE because of liver damage with malnutrition in stage B. So we examined whether branched-chain amino acid (BCAA)improve nutritional status and perform TACE to contribute the prolongation of HCC survival.This study included8 8 patients treatedfor liver cirrhosis with HCC. All patients initially receivedBCAA granules. In patients with unchangedor decreasedAlb levels, BCAA granules were discontinuedandBCAA enrichednutrient was started. TACE for HCC were performedin those with an improvedChild -Pugh score.TACE were performedfollowing the aggressive intervention with BCAA nutritional education in 66 of 88(75%)patients. Finally, overall survival time was significantly extended in TACE group(p0.0001).Timely aggressive nutritional intervention in BCLC stage B HCC, early partial replacement with BCAA enrichednutrient before TACE may consequently contribute to improvement of the treatment outcome of HCC.

The patient was 55-year-old woman, undergoing Hartmann operation by the sigmoid colon diverticulum perforation, 2 years later visited our hospital with abdominal pain. Although lower endoscopy and histological examination could not be performed due to stoma stenosis, we diagnosed cecal carcinoma, liver metastasis, distant lymph node metastasis from CT and PET-CT, CapeOX plus Bmabtherapy and IRIS plus Bmabtherapy were performed. After that, repeated intestinal obstruction due to exacerbated stoma stenosis, metastatic lesion increased in CT examination, furthermore the patient had hope of stoma closure, we decided to resect the primacy tumor, performed subtotal colonectomy and stoma closure. Pathological diagnosis revealed RAS wild type. After surgery, Pmabplus CPT-11 therapy was performed and the metastatic lesion was temporarily shrunk but re-exacerbated, the patient died 2 years 2 months after the first treatment started, 7 months after the primary tumor resection. In the treatment of colorectal cancer, when metastatic lesion is unresectable, chemotherapy is often carried out except when the primary tumor is symptomatic. In our case, although the primary tumor was asymptomatic, an intestinal obstruction due to stoma stenosis was developed and it was necessary to examine whether to use anti-EGFR antibody drugs, therefore we performed operation.

To diagnose postoperative pancreatic fistula(POPF)after pancreaticoduodenectomy(PD)during early post operative days, we evaluatedwhether a change in drain amylase value(DAV), WBC value, or CRP value predicted clinically significant POPF. One hundred thirty patients underwent substomach preserving PD(SSPPD)from 2005 to 2016 in our institution andwe examinedDAV, WBC, andCRP values at POD 1, 3, and 5. Seventy-five patients(57.7%)were equivalent to ISGPF grade A at POD 3.We analyzedthese 75 cases by following 5 factors(DAV at POD 31,500 U/L, DAV at POD 51,000 U/L,WBC value at POD 5≤9,000/mL, DAV of POD 5 decreased to 1/3 from DAV of POD 3, CRP value not improved≥50%from POD 3 to 5) andwere concernedwith the crisis of the grade B/C POPF at final diagnosis after POD 5. In conclusion, DAV of POD 5 decreased to 1/3 from DAV of POD 3, andthe CRP value having not improved(≥50%from POD 3 to 5)were significant risk factors for POPF grade B andC by Cox proportional hazard models.

BACKGROUND In decompensated liver cirrhosis, hypoalbuminemia still persists even after they have been treated with branched-chain amino acid (BCAA) granules. We prospectively evaluated whether BCAA enriched nutrient switched from BCAA granules would increase the serum albumin level, and consequently extend the survival time after hepatocellular carcinoma (HCC) treatment. METHODS This study included 77 patients treated for liver cirrhosis with HCC. After the nutritional assessment, all patients initially received BCAA granules. In patients with unchanged or decreased serum albumin levels, BCAA granules were discontinued and BCAA enriched nutrient was started. Transcatheter arterial chemembolization (TACE) for HCC were performed in those with an improved Child-Pugh score. RESULTS TACE were performed following the aggressive intervention with BCAA nutritional education in 54 of 77 (70.1%) patients. Finally, survival time was significantly extended in the TACE group (P

In general, transcatheter arterial chemoembolization(TACE)can obtain a high therapeutic effect on hypervascular tumors, but the definition of"hypervascular"is unclear. In this study, stainedtumor images on enhancedcomputedtomography( CT)were assessedaccord ing to CT-attenuation value. We investigatedwhether it is possible to estimate the treatment effect(TE)of TACE for hepatocellular carcinomas(HCCs).We studied 50 patients with unresectable HCCs who underwent TACE. A total of 141 tumors were diagnosed as HCC on enhanced CT. We measured andcalculatedthe ratios of CT-attenuation values of HCCs in the arterial phase to normal enhancedliver parenchyma in the portal phase(CT value ratio). We then evaluatedTE on each target nodule by enhancedCT, to examine the correlation between TE andthe CT value ratio.The CT-attenuation values were 119(range 61-180)hounsfieldunits(HU)for HCC and8 3(49-141)HU for liver parenchyma, andthe CT value ratio was 1.47(0.7-2.6). TE was positively correlatedwith the CT value ratio(p=0.0005). The cut-off value that suggestedfavorable results for TACE was 1.7 by receiver operating characteristic(ROC)analysis.The CT value ratio is useful for recognition of hypervascular tumors. We obtained favorable results in cases with a CT value ratio of 1.7 or more.

An 82-year-old woman presented to our hospital with a complaint of frequent vomiting. She was admitted for intensive examination and treatment. Abdominal computed tomography revealed that her stomach was severely expanded, and the wall of the ascending colon was thickened throughout its circumference. Upper gastrointestinal endoscopy uncovered severe stenosis in the pylorus and an elevated lesion resembling a submucosal tumor on the posterior wall of the pylorus. Biopsies of the lesion revealed that it was of Group 1. On colonoscopy, type 2 cancer was found in the ascending colon throughout the circumference, and the biopsies revealed that it was of Group 5. Upper gastrointestinal endoscopy was repeated, and the same result was obtained. The possibility of malignancy could not be excluded; therefore, distal gastrectomy and right colectomy were performed. In terms of histopathology, both resected specimens displayed poorly differentiated adenocarcinoma; however, immunohistochemical studies revealed differences in staining at the two sites. The case was diagnosed as synchronous double cancer involving gastric cancer resembling a submucosal tumor with stenosis in the pylorus and ascending colon cancer. Gastric cancer resembling a submucosal tumor is usually difficult to diagnose on biopsy. If the endoscopic findings reveal an elevated lesion resembling a submucosal tumor with stenosis, then the possibility of carcinoma should be considered, and the most suitable treatment should be selected.
