RESUMEN
Residual pancreatic endocrine function is important for maintaining metabolic status after pancreatectomy and is closely related to patient nutritional status and prognosis. In contrast to insulin secretion, the significance of glucagon secretion following pancreatectomy remains unclear. In this study, we assessed the changes in pancreatic glucagon secretion during pancreatectomy to determine their pathophysiological significance. We evaluated glucagon and insulin secretion using a liquid meal tolerance test before and after pancreatectomy in patients scheduled to undergo pancreaticoduodenectomy (PD) or distal pancreatectomy (DP). After pancreatectomy, fasting plasma glucagon levels were significantly decreased in both the PD (n = 10) and DP (n = 5) groups (PD: from 18.4 to 10.5 pg/mL, p = 0.037; DP: from 21.0 to 12.1 pg/mL, p = 0.043), whereas postprandial plasma glucagon levels were not changed. In the liquid meal tolerance test after pancreatectomy, 60-min plasma glucagon levels and the area under the curve (AUC) for 0-120 min of PD were significantly higher than those for DP (60-min plasma glucagon: PD 49.0 vs. DP 21.7 pg/mL, p = 0.040; AUC0-120min: PD 4,749 vs. DP 3,564 µg min/mL, p = 0.028). Postoperative plasma glucose, serum insulin, and serum C-peptide levels during the liquid meal tolerance test were not significantly different between the two groups. Although fasting plasma glucagon levels decreased, postprandial glucagon responses were maintained after both PD and DP. The difference in residual meal-stimulated glucagon response between PD and DP suggests that a relative excess of postprandial glucagon is involved in the postoperative nutritional status after PD through its impact on systemic metabolic status.

We report a case of unresectable advanced esophageal cancer with an esophageal fistula that was treated with pembrolizumab plus CDDP plus 5-FU therapy and the fistula was closed. A 73-year-old male was diagnosed with cervical-upper thoracic esophageal cancer and esophago-bronchial fistula on CT and esophagogastroduodenoscopy. He underwent chemotherapy containing pembrolizumab. The fistula was closed after 4 cycles and oral intake became possible. Six months have passed since the first visit and chemotherapy is ongoing. The prognosis of esophago-bronchial fistula is extremely poor, and there is no established treatment, including fistula closure. Chemotherapy containing immune checkpoint inhibitors could considered to be expected not only for local control but also for long-term survival.

BACKGROUND: Skeletal muscle loss is a hallmark of malignancies, including advanced gastric cancer (GC). Although programmed death (PD)-1 inhibitors, including nivolumab, have promising anti-cancer effects, there is limited information regarding markers that can predict these therapeutic effects, which include PD-ligand 1 (PD-L1) expression and the tumor mutation burden. Therefore, we evaluated whether the baseline psoas muscle mass index (PMI, a surrogate for skeletal muscle mass) could predict the response of GC to nivolumab treatment, based on progression-free survival (PFS), the objective response rate, and the disease control rate. METHODS: This retrospective study evaluated 31 Japanese patients who received nivolumab for advanced GC and underwent imaging analysis between November 2017 and November 2019. The computed tomography results were used to estimate the psoas major muscle mass. Sex-specific cut-off values were used for the PMI, with low PMI values defined as < 3.6 cm2/m2 for male patients and < 2.9 cm2/m2 for female patients. RESULTS: The median PFS interval was 2.3 months for the patients with stage IV GC. Nine patients (29%) had a low baseline PMI, and these patients had significantly shorter median PFS than the group with a non-low baseline PMI (0.5 months vs. 2.4 months, P = 0.004). CONCLUSIONS: As a surrogate marker for skeletal muscle loss, the PMI may be useful for predicting the response to nivolumab among patients with advanced GC.

BACKGROUND: The permissible liver resection rate for preventing posthepatectomy liver failure (PHLF) remains unclear. We aimed to develop a novel PHLF-predicting model and to strategize hepatectomy for hepatocellular carcinoma (HCC). METHODS: This retrospective study included 335 HCC patients who underwent anatomical hepatectomy at eight institutions between 2013 and 2017. Risk factors, including volume-associated liver-estimating parameters, for PHLF grade B-C were analyzed in a training set (n = 122) via multivariate analysis, and a PHLF prediction model was developed. The utility of the model was evaluated in a validation set (n = 213). RESULTS: Our model was based on the three independent risk factors for PHLF identified in the training set: volume-associated indocyanine green retention rate at 15 min, platelet count, and prothrombin time index (the VIPP score). The areas under the receiver operating characteristic curve of the VIPP scores for severe PHLF in the training and validation sets were 0.864 and 0.794, respectively. In both sets, the VIPP score stratified patients at risk for severe PHLF, with a score of 3 (specificity, 0.92) indicating higher risk. CONCLUSION: Our model facilitates the selection of the appropriate hepatectomy procedure by providing permissible liver resection rates based on VIPP scores.

BACKGROUND: Laparoscopic liver resection (LLR) has evolved as a safe and effective alternative to conventional open liver resection (OLR) for malignant lesions. However, LLR in cirrhotic patients remains challenging. This study analyzed the perioperative and oncological outcomes of LLR for hepatocellular carcinoma (HCC) with cirrhosis compared with OLR using propensity score matching. METHODS: A multicenter retrospective analysis of records of patients who underwent limited liver resection for HCC and were histologically diagnosed with liver cirrhosis between January 2009 and December 2017 in the eight institutions belonging to the Hiroshima Surgical study group of Clinical Oncology was performed. The patients were divided into two groups: the LLR and OLR groups. After propensity score matching, we compared clinicopathological features and outcomes. RESULTS: In total 256 patients with histological liver cirrhosis who underwent limited liver resection for HCC were included in this study; 58 patients had undergone LLR, and the remaining 198 patients OLR. The number of tumors was higher, tumor size was larger, and difficulty score was significantly higher in the OLR group before propensity matching. After the matching, the data of the well-matched 58 patients in each group were evaluated; the intraoperative blood loss was lower in the LLR group (p = 0.004), and incidence of the postoperative complications was significantly higher in the OLR group (p = 0.019). The duration of the postoperative hospital stay was significantly shorter in the LLR group (p < 0.001). There were no differences between two groups in overall survival and recurrent-free survival. CONCLUSIONS: LLR decreased the incidences of postoperative complications, shortened the duration of postoperative hospital stay. Thus, LLR is a safe and feasible procedure even in patients with cirrhosis.

AIM: We aimed to compare the prognostic abilities of two novel liver function-estimating models, Albumin-Bilirubin (ALBI) and Albumin-Indocyanine Green Evaluation (ALICE) grades, in patients with hepatocellular carcinoma. METHODS: Data of 1270 patients who underwent initial hepatectomy for hepatocellular carcinoma between 1986 and 2016 were retrospectively collected from a multi-institutional database. The prognostic impact of each system was analyzed according to the results of the area under the receiver operating characteristic curve, the Cox regression model and the linear trend χ2 -test. RESULTS: The ALBI and ALICE scores, which were obtained before grading status, were significantly correlated (correlation coefficient 0.930; P < 0.001). Both ALBI and ALICE grades stratified well in terms of overall survival, and were found to be independent prognostic factors on multivariate analysis (P < 0.05). The area under the receiver operating characteristic curves for 5-year survival in both groups were equivalent (0.602 vs. 0.614, P = 0.402); however, homogeneity, discriminatory ability, and the Akaike information criterion were superior for the ALICE grade than for the ALBI grade (73.8 vs. 65.7, 43.4 vs. 34.9, and 7204.1 vs. 7212.2, respectively). CONCLUSIONS: Both grading systems could estimate the liver function of patients with hepatocellular carcinoma. Regarding hepatectomy patients, the ALICE grade was a more suitable model than the ALBI grade.
RESUMEN
PURPOSE: The number of elderly patients with colorectal cancer (CRC) treated with surgery has gradually increased. The aim of this study was to evaluate the short-term outcomes in patients ≥80 years of age who underwent laparoscopic or open surgery for CRC using a propensity score-matched analysis to make uniform the patient background characteristics affecting the postoperative morbidity and mortality. METHODS: We compared the short-term outcomes of open vs. laparoscopic surgery in patients with CRC ≥80 years of age between 2010 and 2015. Fifty-two patients undergoing laparoscopic colectomy for CRC were matched to 52 patients undergoing open colectomy with respect to gender, age, body mass index, performance status, prognostic nutritional index, Charlson Comorbidity Index score, tumor-node-metastasis stage, and tumor location. The operative time, blood loss, length of hospital stay, and postoperative complications were investigated. RESULTS: Blood loss was less during laparoscopic surgery than during open surgery (40 vs. 140 ml, p < 0.001). In the laparoscopic surgery group, the hospital stay was shorter (11 vs. 14 days, p < 0.001) and the morbidity rate lower (21.2 vs. 40.4%) than in the open surgery group. The mortality for both groups was similar (0 vs. 1.9% for laparoscopic surgery vs. open surgery). CONCLUSION: Laparoscopic surgery in octogenarians with CRC is a safe, low-invasive alternative to open surgery with less blood loss and a shorter hospital stay.

BACKGROUND: Invasive micropapillary carcinoma (IMPC) is an aggressive variant of adenocarcinoma found in several organs. Recent studies showed that IMPC in colorectal cancer leads to poorer prognosis than conventional colorectal cancer; however, the influence of IMPC on outcomes remains unclear. The present study aimed to identify the clinicopathological characteristics of colorectal cancers with IMPCs, and to evaluate the prognostic significance of IMPCs per se. METHODS: We retrospectively analyzed data from 837 patients with colorectal cancer who underwent surgical treatment. We compared the clinicopathological characteristics and survival outcomes of colorectal cancer patients with IMPCs to those without. RESULTS: Among 837 patients, 130 (16%) had an IMPC component, including 0 (0%) of 18, 9 (4.2%) of 215, 34 (13%) of 254, 59 (24%) of 249 and 28 (27%) of 101 patients with TNM Stages 0, I, II, III and IV, respectively. The 3-year disease-free survival (DFS) rates were significantly worse for Stage III patients with IMPC than for those without (55.3% vs. 78.7% respectively, P < 0.001), but not in patients with other stages. Multivariate analyses of patients with Stage III colorectal cancer found IMPC to be associated with significantly worse DFS (P = 0.026), as were high CEA levels, tumor budding and TNM staging. IMPC was only significantly associated with tumor invasion (P = 0.045) and venous invasion (P = 0.045) in Stage III tumors. CONCLUSIONS: Identifying IMPC components in Stage III colorectal cancer is crucial, as their presence is significantly associated with poorer survival.

Anal metastasis of colorectal cancer is rare, and no standardized effective therapeutic strategy exists. We report a case of abdominoperineal resection for anal metastasis of rectal cancer. A 65-year-old man underwent laparoscopic low anterior resection for rectal cancer in August 2013. Histopathological examination revealed a moderately differentiated adenocarcinoma( tub2, pSS, ly3, v2, pN1, H0, P0, M0, Stage III a, Cur A). In February 2015, he complained of anal discomfort, and tumor markers were elevated. Enhanced CT revealed a 15-mm high-density solid tumor in the anal canal. The results of needle biopsy indicated a moderately differentiated adenocarcinoma. This tumor was suspected to be metastasis from rectal cancer, and we performed abdominoperineal resection. Histopathological examination revealed a moderately differentiated adenocarcinoma, which was the same histological type as the primary rectal cancer and was covered with normal anal epithelium. Collectively, the findings indicated anal metastasis from rectal cancer. The patient is alive without recurrence for 18 months after resection. Anal metastasis should be considered as a differential diagnosis in patients with anal discomfort who have a history of colon/rectal cancer. Abdominoperineal resection may be an effective treatment modality for this condition.

We report a case of a 64-year-old woman with Stage IV breast cancer who responded well to chemotherapy containing bevacizumab. She noticed a left breast tumor with acute progression and was diagnosed as having Stage IV, estrogen receptor( ER)(-), progesterone receptor(PgR)(-), human epidermal growth factor receptor 2(HER2)(-)breast cancer (T4cN3cM1[lymph nodes]). She received 5 courses of adriamycin(60mg/m / 2)plus cyclophosphamide(600mg/m2)(AC therapy)and 4 courses of weekly paclitaxel(PTX 90mg/m / 2)plus bevacizumab(AVA 10 mg/m2)as systemic therapy. Computed tomography(CT)and magnetic resonance imaging(MRI)revealed a complete response(CR). After local resection of the breast tumor and radiation to the breast and regional lymph nodes, capecitabine therapy was initiated. Currently, at 5 months after surgery, no new lesion has been detected.

In a group of 209 colorectal cancer patients with unresectable tumors, 10 patients underwent curative resection after combination chemotherapy at our hospital between 2006 and 2012. Of these 10 patients, 5 presented with peritoneal dissemination at the start of chemotherapy. With the exception of 1 patient with peritoneal recurrence, peritoneal dissemination and liver metastasis were observed in all patients at the time of diagnosis of colorectal cancer. Computed tomography (CT) and/ or positron emission tomography-CT examination revealed disappearance of peritoneal dissemination in response to chemotherapy, except in 1 patient with peritoneal recurrence. After combination chemotherapy, surgical resection of liver metastases and peritoneal dissemination was performed. Pathological and intraoperative findings indicated disappearance of peritoneal dissemination in 3 patients and P2 grade peritoneal dissemination in 1 patient. In the patient with peritoneal recurrence, 1 tumor was completely resected. Interestingly, none of the 3 patients that exhibited complete disappearance of peritoneal dissemination showed peritoneal recurrence, although 1 patient exhibited metastases in the lung and non-regional lymph nodes. In contrast, the patient with P2 grade peritoneal dissemination showed peritoneal recurrence and lung metastasis. All 5 patients survived (duration from diagnosis of colorectal cancer, 31-83 months). Herein, we report the use of combination chemotherapy to achieve the disappearance of peritoneal dissemination, changing unresectable colorectal cancer with peritoneal dissemination into resectable cancer.

INTRODUCTION AND IMPORTANCE: Median arcuate ligament syndrome (MALS) is a rare disease characterized by compression of the celiac artery (CA) by the median arcuate ligament (MAL). A small proportion of pancreaticoduodenal artery (PDA) aneurysms are caused by compression of the CA by the MAL. Here, we report a case of rupture of a PDA aneurysm associated with MALS that was treated with coil embolization followed by MAL resection. CASE PRESENTATION: A 49-year-old man lost consciousness due to hypovolemic shock in the hospital two days after appendectomy. Contrast-enhanced multi-detector row computed tomography (MD-CT) showed a retroperitoneal hematoma and extravasation from the pancreaticoduodenal arcade vessels, therefore emergency angiography was performed. An aneurysm was detected in the anterior inferior PDA and coil embolization was performed for the inferior PDA. Three months after embolization, MAL resection was performed to prevent rebleeding from the PDA. Six months have passed after the surgery, the patient had no CA restenosis or PDA aneurysms. CLINICAL DISCUSSION: MALS is a rare disease that results from the compression of the CA by the MAL. PDA aneurysms are associated with CA stenosis, and compression of the CA by the MAL is the most frequently reported cause of CA stenosis. There is no established treatment for CA stenosis after a PDA aneurysm rupture due to MALS. CONCLUSION: It is suggested that MAL resection may be effective in reducing shear stress in the pancreaticoduodenal arcade. Improving blood flow through the CA by MAL resection might reduce risk of PDA aneurysm recurrence.
RESUMEN
We here report a case of pancreatic duct rupture associated with high-grade pancreatic intraepithelial neoplasia treated by radical resection. A 71-year-old man presented to our hospital because of abdominal bloating. Diagnoses of early-stage pancreatic body cancer with pancreatic duct rupture, pancreatic ascites, and formation of a pseudocyst were made on the basis of blood tests, multidetector dynamic computed tomography, endoscopic ultrasonography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography. After achieving control of the ascites by placement of a pancreatic duct stent and aspiration of the pseudocyst, distal pancreatectomy with D2 lymph node dissection was performed. Intraoperative cytologic examination of the ascites was negative. The pathological diagnosis was high-grade pancreatic intraepithelial neoplasia in the pancreatic body. The branched pancreatic duct was occluded and dilated by acute inflammation around the pancreatic neoplasm, the inflammation being in the region of the dilated branched pancreatic duct and having caused its rupture. To the best of our knowledge, this is the first published report of pancreatic duct rupture associated with high-grade pancreatic intraepithelial neoplasia.

BACKGROUND: Liver resection for hepatocellular carcinoma beyond the Barcelona Clinic Liver Cancer criteria remains controversial. Strict candidate selection is crucial to achieve optimal results in this population. This study explored postoperative outcomes and developed a preoperative predictive formula to identify patients most likely to benefit from liver resection. METHODS: In total, 382 patients who underwent liver resection for hepatocellular carcinoma beyond the Barcelona Clinic Liver Cancer resection criteria between 2000 and 2017 were identified from a multicenter database with the Hiroshima Surgical study group of Clinical Oncology. An overall survival prediction model was developed, and patients were classified by risk status. RESULTS: The 5-year overall survival after curative resection was 50.0%. Overall survival multivariate analysis identified that a high a-fetoprotein level, macrovascular invasion, and high total tumor burden were independent prognostic risk factors; these factors were used to formulate risk scores. Patients were divided into low-, moderate-, and high-risk groups; the 5-year overall survival was 65.7%, 49.5%, and 17.0% (P < .001), and the 5-year recurrence-free survival was 31.3%, 26.2%, and 0%, respectively (P < .001). The model performance was good (C-index, 0.76). Both the early and extrahepatic recurrence increased with higher risk score. CONCLUSION: The prognosis of patients with hepatocellular carcinoma beyond the Barcelona Clinic Liver Cancer resection criteria depended on a high a-fetoprotein level, macrovascular invasion, and high total tumor burden, and risk scores based on these factors stratified the prognoses. Liver resection should be considered in patients with hepatocellular carcinoma beyond the Barcelona Clinic Liver Cancer criteria with a low or moderate-risk score.

Morgagni hernia is a rare form of diaphragmatic hernia. It is located at the anterior edge of the diaphragm and does not have an anterior rim. It is difficult to achieve a secure closure and maintain the tension of closure with laparoscopic surgery. We have performed laparoscopic resection of colorectal cancer and hernia repair simultaneously. An 89-year-old woman underwent laparoscopic hernia repair and ileocecal resection simultaneously. Regarding hernia repair, we considered that it would be difficult to use a mesh from the viewpoint of infection due to the colectomy. Therefore, we have done the extra-abdominal suture method. After laparoscopic ileocecal resection, a small incision was made in the epigastric region, and Morgagni hernia repair was performed with extra-abdominal sutures. She had no recurrence of either colon cancer or hernia for 22 months post-operatively. The extra-abdominal suture method can provide secure closure of the hernia orifice for Morgagni hernia.
RESUMEN
Distal gastrectomy (DG) with lymph node dissection is considered as the standard treatment for gastric cancer. Ischemic necrosis of the gastric remnant is a rare but serious complication of DG that requires careful consideration for early diagnosis and treatment to lower the associated mortality rate. A 71-year-old male presented to our hospital with hyperglycemia and was evaluated for suspected diabetes. The patient's medical history was otherwise unremarkable. Computed tomography (CT) revealed a thickening of the stomach wall, with follow-up esophagogastroduodenoscopy revealing type 3 gastric cancer in the greater curvature of the antrum. Biopsy specimen confirmed a pathological diagnosis of mucinous adenocarcinoma, with a clinical diagnosis of cT3N0M0, cStageIIB. An open DG with Billroth I reconstruction was performed, without incident. On postoperative day 1, the patient developed a high fever, abdominal pain, and elevated white blood cell count (12,200/µL). On postoperative day 2, his C-reactive protein level increased to >30 mg/dL. CT revealed an edematous thickening of the stomach wall, with poor mucosal enhancement of the remnant stomach and thinning of the anastomosis wall, with air nearby. Emergency surgery was performed for suspected leakage. Intraoperative findings showed no evidence of leakage. Intraoperative endoscopy revealed a necrotic gastric remnant, and we performed a total remnant gastrectomy with Roux-en Y reconstruction. The patient was discharged in a stable condition, 25 days after the first surgery. Although ischemic necrosis of the gastric remnant is a rare complication, its possibility should be carefully considered after DG, for early diagnosis and treatment.
RESUMEN
INTRODUCTION: A decompensated cirrhosis sometimes develops collateral circulation due to severe fibrosis. Rupture of this collateral circulation can induce a fatal situation. CASE PRESENTATION: A 59-year-old man with alcoholic cirrhosis was admitted to our emergency department with a chief complaint of impaired consciousness. The patient had hypotension upon arrival, and enhanced computed tomography (CT) revealed a massive hemoperitoneum. Imaging examinations, including interventional radiography, could not identify the source of bleeding preoperatively; therefore, emergency surgery was performed. Intraoperatively, a collapsed small vessel connecting liver segment 4 and the expanded umbilical vein as collateral circulation due to portal hypertension was detected as the source of bleeding. Ligating the stump of the small vessel and postoperative intensive care saved the patient's life. The patient was discharged from our hospital 14 days after the surgery. CLINICAL DISCUSSION: A rupture of the umbilical vein associated with cirrhosis is rare and causes a critical situation because of the fast blood flow in the collateral circulation caused by portal hypertension. Moreover, the amount of bleeding tends to increase since the abdominal cavity is a free space and patients with cirrhosis have coagulopathies, including thrombocytopenia and prolonged prothrombin time. Although a retrospective review of the enhanced CT image could identify the minute findings, arterial portography was insufficient to detect bleeding from the umbilical vein. Therefore, emergency exploratory laparotomy was required for the diagnosis and treatment. CONCLUSION: Rupture of the reopened umbilical vein can cause idiopathic spontaneous hemoperitoneum in patients with decompensated cirrhosis.
RESUMEN
INTRODUCTION: The number of elderly patients with colorectal cancer has gradually increased. Laparoscopic colorectal surgery is widely used to approach colorectal cancer. The aim of this study was to evaluate long-term outcomes in octogenarians who underwent laparoscopic colorectal surgery for colorectal cancer. METHODS: This study included 158 patients aged 80 or over who underwent surgery for colorectal cancer between 2010 and 2015. We compared long-term outcomes of a laparoscopic colorectal surgery group with those of an open colorectal surgery group by propensity score matching equalizing factors that could affect prognosis such as prognostic nutritional index and Charlson comorbidity index score. RESULTS: Forty-eight pairs were selected after propensity score matching. The cancer-specific 5-year survival rate was 97.1% in the laparoscopic colorectal surgery group and 87.6% in the open colorectal surgery group (P = .17). The overall 5-year survival rate was 77.3% in the laparoscopic colorectal surgery group and 73.9% in the open colorectal surgery group (P = .32). The 5-year recurrence-free survival rate was 95.1% in the laparoscopic colorectal surgery group and 85.4% in the open colorectal surgery group (P = .14). CONCLUSION: Laparoscopic colorectal surgery for octogenarians with colorectal cancer achieves similar oncological outcomes to open colorectal surgery and should be considered as a treatment option.

To decrease complications associated with the treatment of coeliac axis (CA) stenosis due to median arcuate ligament (MAL) syndrome in pancreaticoduodenectomy, we performed combined preoperative endovascular stenting and intraoperative MAL resection. This technique can secure the CA blood flow to the hepatic artery before surgery in one stage and prevent CA restenosis and stent dislocation because there is no extrinsic compression of the CA after MAL resection.

We herein report the first case of rectal stenosis that developed after internal hemorrhoid treatment with aluminum potassium sulfate and tannic acid (ALTA) therapy that was successfully treated by laparoscopic surgery. A 72-year-old man suffered from a fever and rectal stenosis after undergoing internal hemorrhoid treatment with a submucosal injection of ALTA at a previous clinic. Three months after ALTA therapy, he developed frequent mucous and bloody stools. Lower intestinal tract endoscopy revealed circumferential severe rectal stenosis. He was therefore referred to our hospital. The patient suffered from frequent stool build-up and difficulty defecating. We performed balloon-dilatation intervention. The stenosis was not improved at all. Five months after ALTA therapy, we performed laparoscopic low anterior resection with diverting ileostomy. Three months after the operation, ileostomy takedown was performed. The patient has experienced no rectal stenosis in the 2 years since his radical operation.
