RESUMO

BACKGROUND: Subphrenic abscess caused by Clostridium perfringens is rare after hepatic resection. We herein report such a case after hepatic resection for hepatocellular carcinoma following treatment of emphysematous cholecystitis. CASE PRESENTATION: A 69-years-old man with chronic hepatitis B, was admitted to our hospital for right subcostal pain and loss of appetite. Computed tomography (CT) revealed emphysematous cholecystitis, for which percutaneous transhepatic gallbladder drainage was performed. Clostridium perfringens was identified from the culture of the bile. Imaging studies immediately demonstrated hepatocellular carcinoma with right lobe of the liver, for which the patients underwent hepatic resection and cholecystectomy concomitantly. After operation, the patient developed emphysematous subphrenic abscess on postoperative day 15, for which CT-guided percutaneous drainage was performed. Clostridium perfringens was identified from the culture of the abscess fluid. The patient was given Ciprofloxacin and Clindamycin and made a satisfactory recovery. The patient was discharged on POD 95 and remains well with no evidence of tumor recurrence as of 8 years after resection. CONCLUSION: We herein reported a subphrenic abscess due to Clostridium perfringens after hepatic resection for hepatocellular carcinoma following emphysematous cholecystitis.

RESUMO

BACKGROUND AND AIM: The relationship between gastroesophageal reflux disease (GERD) and sleep disturbance has recently been pointed out and is garnering substantial attention. Although there are reports that point out the effectiveness of medical treatment for sleep disturbance associated with GERD, examinations of the pathological condition, including reflux during sleep, are inadequate. In the present study, we evaluated the recumbent reflux in patients with GERD and sleep disturbance using multichannel intraluminal impedance pH (MII-pH), and attempted to suppress recumbent reflux by surgical treatment to examine the pathophysiology of patients with GERD and sleep disturbance. MATERIALS AND METHODS: Of the 47 patients with GERD-related diseases in whom laparoscopic fundoplication was performed at The Jikei University Hospital from January 2016 to June 2017, 31 patients (average age: 55.9 ± 13.8 years, male in 25), excluding 9 with surgical indications only for esophageal hiatal hernia and 7 without postoperative evaluation, were the subjects of this study. All surgical procedures were performed by the Toupet method. We used the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep disturbance, setting 5.5 as the cut-off value, based on the report by Doi et al., with any conditions beyond this value deemed sleep disturbance. The evaluation of gastroesophageal reflux was carried based on the MII-pH using the Sleuth, manufactured by Sandhill Corporation, with an automatic analysis carried out by computer. Furthermore, recumbent abnormal reflux was defined as recumbent all reflux (times) > 7. All evaluations were performed preoperatively and at 3 months after the operation. The data were expressed in medians and interquartile ranges, with p < 0.05 defined as statistically significant by the Mann-Whitney, Wilcoxon, or Chi-squared test. RESULTS: Although sleep disturbance was found in 19 cases (61%), 8 (42%) of which were actually confirmed as nighttime abnormal reflux, of whom 5 cases (63%) showed significant improvement in their sleep disturbance following the operation, with a PSQI score of lower than 5.5. Among these 5 cases, postoperative recumbent abnormal reflux was also significantly reduced as compared with the preoperative condition (17 vs. 2 times/day, p = 0.042). Furthermore, sleep disturbance improved and recumbent abnormal reflux also decreased in two cases, with sleep disturbance improved by controlling the nighttime reflux via surgery in a total of 7 cases (87.5%). Although the PSQI score was as high as 14 points before and after the operation in one case, the rate of recumbent abnormal reflux was remarkably reduced, with sleep disturbance and recumbent reflux considered irrelevant. Furthermore, regarding the frequency of recumbent acid/non-acid reflux, while non-acid reflux was significantly more frequent in the patients with recumbent reflux complications (9 vs. 1 time/day, p < 0.001), there was no marked difference in the frequency of acid reflux. CONCLUSIONS: Among cases with GERD and sleep disturbance, approximately one-third of them showed findings suggestive of the involvement of recumbent reflux in sleep disturbance, with reflux characterized by non-acid reflux.

RESUMO

BACKGROUND/AIM: The prognosis of pancreatic cancer remains poor with a high incidence of recurrence even after curative resection. The aim of this study was to investigate prognostic factors in patients with recurrent pancreatic cancer using the multicenter database. PATIENTS AND METHODS: The subjects were 196 patients with recurrent pancreatic cancer who underwent resection between 2008 and 2015. We retrospectively investigated the relation between clinicopathological characteristics of the patients and overall survival from recurrence using univariate and multivariate analyses. RESULTS: In univariate analysis, the positive lymphatic invasion (p=0.0240), time to recurrence from resection <1 year (p<0.0001), sites of recurrence except for local or lymph node (p=0.0273), liver recurrence (p=0.0389) and peritoneal recurrence (p<0.0001) were significantly associated with poor overall survival from recurrence. In multivariate analysis, time to recurrence from resection <1 year (p<0.0001) and peritoneal recurrence (p<0.0001) were independently associated with poor overall survival from recurrence. CONCLUSION: Time to recurrence from resection <1 year and peritoneal recurrence were significant independent predictors of poor overall survival from recurrence in patients with recurrent pancreatic cancer.

RESUMO

Background: Endoscopic biliary stenting (EBS) using a plastic stent is currently widely performed for preoperative biliary drainage for periampullary cancer. The aim of this study was to investigate the risk factors and surgical outcomes of stent dysfunction after EBS in patients who underwent pancreaticoduodenectomy (PD). Patients and Methods: The subjects were 85 patients who underwent PD after EBS using a plastic stent for malignant biliary obstruction between November 2008 and January 2019. We retrospectively investigated the relationship between perioperative patient characteristics and the incidence of stent dysfunction. Stent dysfunction was defined as insufficient biliary drainage and the presence of various symptoms, including high fever and abdominal pain, with elevated serum hepatobiliary enzyme levels or bilirubin level. Results: Stent dysfunction occurred in 38% of patients. In univariate analysis, serum total bilirubin before the initial EBS ≥15 mg/dL (P = .0244) and a stent diameter of 7 Fr (P = .0044) were significant predictors of stent dysfunction. In multivariate analysis, the only significant independent predictor of stent dysfunction was a stent diameter of 7 Fr (P = .0227). In the patients without stent dysfunction, duration from the initial EBS to the operation was significantly shorter than that in the patients with stent dysfunction (P = .0055). Operation time, intraoperative blood loss, postoperative pancreatic fistula, and bile leakage were comparable between the two groups. Conclusion: Seven French stent was the significant independent predictor of stent dysfunction after EBS in patients who underwent PD.

RESUMO

BACKGROUND/AIM: Zinc finger protein ZKSCAN3 (ZNF306) is a promising oncogene candidate in colon, bladder, breast, uterine cervical, and prostate cancers. The present study aimed to investigate ZKSCAN3 protein expression in gastric carcinoma patient tissues and to evaluate oncological outcomes in these patients. MATERIALS AND METHODS: ZKSCAN3 was detected using the anti-ZKSCAN3 rabbit polyclonal antibody. For immunohistochemical examination, we used paraffin-embedded specimens from 87 consecutive patients with gastric cancer who underwent gastrectomy. We investigated ZKSCAN3 expression in relation with patient prognosis and clinicopathological factors. RESULTS: ZKSCAN3 was detected in 28 (32.2%) tumour specimens, with significant association with lymphatic system invasion and distant metastasis. Patients with ZKSCAN3-positive tumours had worse overall survival (OS) than those with ZKSCAN3-negative tumours based on log-rank testing. Furthermore, multivariate analysis revealed that ZKSCAN3 was an independent prognostic parameter for OS (hazard ratio: 2.6379, p=0.0164). CONCLUSION: ZKSCAN3 is a potential novel prognostic factor in gastric cancer patients.

RESUMO

AIM: In colorectal cancer surgery, the efficacy of intestinal blood flow evaluation with the indocyanine green (ICG) fluorescence method using the VISERA ELITE2 system was investigated. PATIENTS AND METHODS: Participants in this study comprised 50 patients who underwent elective laparoscopic colorectal cancer surgery at the Department of Surgery, the Jikei Daisan Hospital. With the ICG fluorescence method, whether it was necessary to change the intestinal transection line for anastomosis was evaluated. RESULTS: For three cases of rectal cancer, the oral transection line determined from macroscopic observation was judged to offer insufficient blood flow according to the ICG fluorescence method. The transection line for anastomosis was changed according to fluorescence. None of these cases showed complications. CONCLUSION: The ICG fluorescence method may allow safe anastomosis in colorectal surgery for cancer.

RESUMO

PURPOSE: To compare the treatment results of needlescopic surgery with those of the conventional method for achalasia, using propensity score-matching. METHODS: Propensity score-matching was performed based on five factors: age, gender, body mass index, extended form, and maximum expansion diameter, to extract 28 cases each for a needlescopic group and a conventional group. RESULTS: There were no significant differences between the needlescopic group and the conventional group, in operative time (165 min vs. 170 min, p = 0.682), estimated blood loss (both ≒ 0 ml, p = 0.426), or post-operative hospital stay (4 vs. 4 days, p = 0.248). Although the follow-up period was significantly longer in the conventional group (6 vs. 105 months, respectively; p < 0.001), there was no difference in the post-operative symptom scores for difficulty in swallowing and chest pain or the degree of satisfaction (p = 0.563, p = 0.142, p = 0.342, respectively). Furthermore, there was no difference in the post-operative clearance rate, with both groups found to be favorable (p = 0.758, p = 0.790, p = 1.000, p = 1.000, respectively). CONCLUSIONS: The short-term results of needlescopic surgery for achalasia were good and equivalent to those of the conventional method.

RESUMO

PURPOSE: In rectal cancer surgery, an insufficient distal margin (DM) is associated with a high risk of local recurrence, whereas an excessive DM will cause low anterior resection syndrome, impairing quality of life. This study aimed to identify the factors that affect the distance between the colorectal resection site and the tumor to optimize achieving the correct DM. METHODS: The subjects of this study were 219 patients who underwent resection for primary rectal cancer in our department between January 2006 and July 2014. According to Japanese guidelines, DM (rDM) was based on the tumor location, but the pathological DM (pDM) was measured from surgical specimens. The patients were divided into two groups: the pDM-less-than-rDM group (pDM < rDM) and the pDM-greater-or-equal-to-rDM group (pDM ≥ DM). The factors associated with the DM in the two groups were compared. RESULTS: In the pDM < rDM group, the tumor distance from the anal verge was shorter (p = 0.001) and significantly more patients underwent laparotomy (p = 0.047). CONCLUSION: The DM tended to be shorter than that planned by the surgeon in patients with lower rectal cancers and those treated by laparotomy,; therefore, when performing rectal resection, care must be taken to ensure that the pDM is not shorter than the rDM.

RESUMO

BACKGROUND: To achieve safety of the operation, preoperative simulation became a routine practice for hepatobiliary and pancreatic (HBP) surgery. The use of intraoperative ultrasonography (IOUS) is essential in HBP surgery. There is a limitation in the use of IOUS in laparoscopic surgery (LS), for which a new intraoperative system is expected. We have developed an image-guided navigation system (IG-NS) for open HBP surgery since 2006, and we have applied our system to LS. The aim of this study is to evaluate the results of clinical application of IG-NS in LS. MATERIALS AND METHODS: Eight patients underwent LS using IG-NS; LS consisted of cholecystectomy and hepatectomy in four patients each. After registration, the 3D models were superimposed on the surgical field. We performed LS while observing the navigation image. Moreover, we developed a support system for operations. RESULTS: The average registration error was 8.8 mm for LS. Repeated registration was effective for organ deformation and improved the precision of IG-NS. By using various countermeasures, identification of the tumor's position and the setting of the resection line became easy. CONCLUSION: As IG-NS provided real-time detailed and intuitive information, this intraoperative assist system may be an effective tool in LS.

RESUMO

Fusobacterium nucleatum (F. nucleatum), which has been associated with colorectal carcinogenesis, can impair anti-tumour immunity, and actively invade colon epithelial cells. Considering the critical role of autophagy in host defence against microorganisms, we hypothesised that autophagic activity of tumour cells might influence the amount of F. nucleatum in colorectal cancer tissue. Using 724 rectal and colon cancer cases within the Nurses' Health Study and the Health Professionals Follow-up Study, we evaluated autophagic activity of tumour cells by immunohistochemical analyses of BECN1 (beclin 1), MAP1LC3 (LC3), and SQSTM1 (p62) expression. We measured the amount of F. nucleatum DNA in tumour tissue by quantitative polymerase chain reaction (PCR). We conducted multivariable ordinal logistic regression analyses to examine the association of tumour BECN1, MAP1LC3, and SQSTM1 expression with the amount of F. nucleatum, adjusting for potential confounders, including microsatellite instability status; CpG island methylator phenotype; long-interspersed nucleotide element-1 methylation; and KRAS, BRAF, and PIK3CA mutations. Compared with BECN1-low cases, BECN1-intermediate and BECN1-high cases were associated with lower amounts of F. nucleatum with odds ratios (for a unit increase in three ordinal categories of the amount of F. nucleatum) of 0.54 (95% confidence interval, 0.29-0.99) and 0.31 (95% confidence interval, 0.16-0.60), respectively (Ptrend < 0.001 across ordinal BECN1 categories). Tumour MAP1LC3 and SQSTM1 levels were not significantly associated with the amount of F. nucleatum (Ptrend > 0.06). Tumour BECN1, MAP1LC3, and SQSTM1 levels were not significantly associated with patient survival (Ptrend > 0.10). In conclusion, tumour BECN1 expression is inversely associated with the amount of F. nucleatum in colorectal cancer tissue, suggesting a possible role of autophagy in the elimination of invasive microorganisms. © 2019 Pathological Society of Great Britain and Ireland.

RESUMO

BACKGROUND/AIM: We aimed to assess surgical outcome and long-term survival after elective hepatic resection for hepatocellular carcinoma (HCC) and colorectal liver metastasis (CRLM) in patients aged 80 years or older. PATIENTS AND METHODS: This study included 100 patients aged 70 years or older, who underwent hepatic resection for HCC or CRLM between January 2000 and December 2012. Outcomes and clinicopathological data were compared between the elderly (aged 70-79 years; n=84) and extremely elderly groups (aged 80 years or older; n=16). RESULTS: Incidence of postoperative complications, in-hospital mortality, and postoperative OS in the extremely elderly group were comparable with those of the elderly group. In patients with HCC, the extremely elderly group was associated with shorter DFS (p=0.030) in univariate analysis, while multivariate analysis showed significant and independent factors of cancer recurrence. CONCLUSION: Hepatic resection for HCC and CRLM in patients aged 80 years and older may be safe and acceptable with appropriate selection. For HCC in patients aged 80 years and older, hepatic resection may be effective when negative surgical margins can be achieved.

RESUMO

INTRODUCTION: Reports on inguinal hernia repair after femoral arterial bypass are limited, and a recommended procedure has not been established. PRESENTATION OF CASE: Case 1. A 77-year-old man who had a history of femoro-femoral arterial bypass (FFB) for limb graft occlusion following endovascular aortic repair for abdominal aortic aneurysm presented with a left inguinal hernia. CT revealed an inguinal hernia and the FFB graft was identified in the subcutaneous plane. We selected mesh-plug repair under local infiltration anesthesia and his postoperative course was uneventful. Case 2. A 73-year-old man who had a history of FFB for occlusion the branch of the graft of endovascular stent for abdominal aortic aneurysm presented with a left inguinal hernia. CT revealed an inguinal hernia and the FFB graft was identified in the subcutaneous plane. We performed mesh-plug repair under general anesthesia and his postoperative course was uneventful. The patients are free of recurrence of the hernia or complication of the FFB graft as of 13 months and 30 months after the surgery, respectively. DISCUSSION: We herein report two cases of successful open mesh plug repair for inguinal hernia after FFB. CONCLUSION: The mesh plug repair is safe and useful for the treatment of inguinal hernia after FFB, for which preoperative CT is helpful for understanding precise anatomy which facilitates surgical planning.

RESUMO

INTRODUCTION: A preoperative scoring system to predict carcinoma in patients with gallbladder polyps (GBPs). METHODS: Preoperative parameters of patients with GBPs who underwent cholecystectomies were used to construct a scoring system to ascertain the risk of malignancy (reference group). The scoring system developed from this approach was applied to the validation group. RESULTS: In the reference group, 11.5% of patients had carcinomas, in whom the median age was 68 years and the polyp size was 16.9 mm. According to the univariate analysis, the significant factors for carcinoma were age ≥65 years, the presence of gallstones, polyp size ≥13 mm, solitary polyp, and sessile polyp. Age ≥65 years and polyp size ≥13 mm were significant factors according to the multivariate analysis. From these results, we developed a preoperative scoring system to predict carcinoma. The patients were divided into 1 of 2 groups: low-risk and high-risk and their malignancy rates were 4.1 and 61.1% respectively (p < 0.001). In the validation group, the malignancy rate was higher for those in the high-risk group (p = 0.016). CONCLUSIONS: The proposed preoperative scoring system based on simple clinical variables appears to be useful for predicting malignancy in patients with GBPs.

RESUMO

BACKGROUND: Calcifying fibrous tumor (CFT) is a rare benign soft tissue lesion. CASE PRESENTATION: A 30-year-old woman was admitted to our hospital with complaints of epigastralgia. A 15-mm submucosal tumor was identified in the greater curvature of the superior body of the stomach by upper gastrointestinal endoscopy. Endoscopic ultrasonography revealed a hypoechoic lesion with an acoustic shadow consistent with calcification. Computed tomography showed a gastric tumor with calcification. A gastrointestinal stromal tumor was diagnosed, and gastric wedge resection was performed by laparoscopy and endoscopy cooperative surgery. On pathological examination, the tumor was identified to be a CFT. Postoperative serum IgG4 levels were 26.0 mg/dl, which supported the diagnosis of probable immunoglobulin G (IgG) 4-related disease, according to the comprehensive diagnostic criteria of IgG4-related disease. The patient was discharged on postoperative day 7 and remains well with no evidence of tumor recurrence for 2 years after resection. CONCLUSION: We herein reported a patient with a gastric CFT suspected to be complicated with immunoglobulin G4-related disease that was successfully treated by laparoscopy and endoscopy cooperative surgery.

RESUMO

BACKGROUND: Chest pain reduces the quality of life of patients with achalasia. Although laparoscopic Heller-Dor surgery (LHD) is a standard surgical treatment for achalasia, its therapeutic efficacy for chest pain is not clear. The present study evaluated the therapeutic efficacy of LHD for chest pain and tried to identify factors associated with the relief of chest pain. METHODS: The study included 244 patients with preoperative chest pain who underwent LHD as the first surgical intervention. The questionnaire-based symptom frequency score was multiplied by the severity score, and the calculated metric was defined as the symptom score. The study population was stratified, by the change in the chest pain symptom score, into Complete Remission (CR), Partial Remission (PR), and No Remission (NR) groups, which were compared for patient background and surgical outcome. Multivariate analysis was also performed to determine factors associated with the relief of chest pain. RESULTS: As for preoperative clinicopathological conditions, the CR subgroup was older (p = 0.0169) with fewer previous balloon dilatations (p = 0.009). Although no difference was detected in the surgical outcome, the NR group had higher postoperative symptom scores for both difficulty in swallowing and vomiting and a lower score for patient satisfaction with surgery (p = 0.0141). Multivariate analysis detected two factors associated with CR: disease duration over 60 months and less than two previous balloon dilatations. CONCLUSIONS: LHD improved chest pain symptoms in 90% of patients with achalasia. The patients who achieved relief of chest pain were characterized by disease duration over 60 months and less than two previous balloon dilatations.

RESUMO

BACKGROUND/AIM: This study aimed to identify risk factors for recurrence of patients with stage III colorectal cancer by assessing clinicopathological features. PATIENTS AND METHODS: The study included 231 patients with stage III colorectal cancer who underwent curative resection between 2006 and 2012 at the Department of Surgery of the Jikei University Hospital, Tokyo, Japan. Clinicopathological data of the patients were retrospectively evaluated. RESULTS: The recurrence rate was 27.7% (64/231) in the study group. The univariate analysis for recurrence identified five risk factors: site of primary tumor (rectal cancer), surgical procedure (open surgery), preoperative serum CEA level (>5 ng/ml), preoperative serum CA19-9 level (>37 U/ml), and number of metastatic lymph nodes (over three metastases). The multivariate analysis for recurrence identified three risk factors: rectal cancer, preoperative serum CEA level >5.0 ng/ml 95%, and more than three metastatic lymph nodes. CONCLUSION: The risk factors for stage III colorectal cancer recurrence seem to be rectal cancer, preoperative serum CEA level >5.0 ng/ml, and more than three metastatic lymph nodes.

RESUMO

BACKGROUND/AIM: After primary resection of hepatocellular carcinoma (HCC), the impact of patient's characteristics at the initial hepatectomy, on long-term remnant liver function has not been reported. The aim of this study was to identify factors associated with the deterioration of remnant liver function among patients who developed recurrent HCC. PATIENTS AND METHODS: A total of 51 patients with intrahepatic recurrence after initial hepatic resection for HCC were included. We retrospectively investigated the relation between patient characteristics and the degree of deterioration of remnant liver function upon recurrence. RESULTS: In univariate analysis, significant predictors of deterioration of remnant liver function consisted of preoperative gastro-esophageal varices (p=0.0101), preoperative transcatheter arterial chemoembolization (p=0.0230) and hepatectomy beyond Makuuchi's criteria (p=0.0101). In multivariate analysis, the only significant independent predictor of deterioration of remnant liver function was hepatectomy beyond Makuuchi's criteria (p=0.0498). CONCLUSION: Hepatectomy beyond Makuuchi's criteria at the initial hepatectomy may predict deterioration of remnant liver function upon recurrence of HCC.

RESUMO

BACKGROUND: Benign anastomotic stricture after esophagectomy and reconstruction adversely affects oral intake and can increase the risk of aspiration pneumonia. Some patients experience relapse that requires frequent endoscopic dilatations. This study aimed to investigate whether the endoscopic appearance of anastomosis during the early postoperative period is associated with the complexity of subsequent anastomotic strictures. METHODS: Data of 213 patients who underwent esophagectomy with gastric tube reconstruction and early postoperative endoscopy between July 2008 and September 2018 were prospectively collected. Relationships among various risk factors, including the severity of mucosal degeneration of the anastomosis and complexity of anastomotic stricture, were studied using multivariate logistic regression analysis. RESULTS: Fifty-three patients (25%) developed anastomotic strictures at a median of 55 days after surgery, requiring a median of 5 endoscopic dilations. In multivariate analysis, severe mucosal degeneration was the only significant risk factor for any type of anastomotic stricture (P < 0.001). Twenty-seven patients (51%) developed refractory anastomotic strictures. In multivariate analysis, younger age (< 65 years) (P = 0.01), lack of neoadjuvant therapy (P = 0.02), severe mucosal degeneration (P = 0.03), and stricture development within 55 days (P = 0.01) were the risk factors for refractory stricture. The analysis of the risk factors for severe mucosal degeneration revealed that comorbidities and anastomotic techniques were independently correlated (P < 0.01). CONCLUSIONS: Early postoperative severe mucosal degeneration of esophagogastrostomy was the only predictor of strictures, regardless of their type. Mucosal degeneration, early postoperative stricture, younger age, and front surgery were associated with refractory anastomotic strictures.

RESUMO

BACKGROUND/AIM: To evaluate whether the serum levels of CEA or CA19-9 concentration is a useful predictor of survival in patients with metastatic colon cancer (mCC). PATIENTS AND METHODS: Between 2012 and 2015, 113 patients with mCC who underwent chemotherapy according to the Japanese Colorectal Cancer Treatment Guidelines at four Jikei University Hospitals were enrolled in this study. The two serum tumor makers, CEA and CA19-9 were measured before first-line chemotherapy and at four months thereafter. RESULTS: Serum CA19-9 concentration at four months after first-line chemotherapy (p=0.003, HR=3.761) and first-line chemotherapy including oxaliplatin (p=0.038, HR=0.312) were independent predictors of survival in patients with mCC. By excluding the transverse colon, only serum CA19-9 concentration at four months after first-line chemotherapy (p=0.005, HR=3.660) was identified as the predictor of survival. CONCLUSION: Serum CA19-9 concentration after first-line chemotherapy seems to be a useful predictor of survival in patients with mCC.
