RESUMO

PURPOSE: The aim of the study was to compare proportions of chronic postoperative inguinal pain (CPIP) and other surgical outcomes between transinguinal preperitoneal repair with modified Kugel patch (MK) and Lichtenstein repair (LR). METHODS: Two-hundred adult male patients with primary unilateral inguinal hernia were randomized into MK or LR groups. The primary endpoint was CPIP, pain at 6 months after surgery. Secondary outcomes included recurrence rate, incidence of postoperative complications, time until return to activities, inguinal pain and sensory disturbances assessed at 1 week, 1 month, 3, 6, and 12 months after the operation using an 11-point numerical rating scale (NRS). The study was an intention-to-treat analysis. RESULTS: In comparison of MK (n = 100) and LR (n = 100) with similar backgrounds, proportions of CPIP were similar (7.2 vs. 11.1%, p = 0.3452). Favorable outcomes for MK were duration of operation (32 vs. 40 min, p < 0.0001), NRS of foreign body sensation at 1 year (0 [0-1] vs. 0 [0-2], p = 0.0067), and NRS of numbness at 1 month (0 [0-1] vs. 0 [0-3], p = 0.0078) after the operation. CONCLUSIONS: In regard to CPIP, the short-term results of MK and LR were similar.

RESUMO

A 54-year-old woman underwent living donor liver transplantation (LDLT) for primary biliary cholangitis (PBC) three years earlier. She took cyclosporine A (CyA) 150 mg/day as immunosuppression for prevention of rejection and PBC recurrence. Routine upper gastrointestinal endoscopy showed chronic atrophic gastritis and hyperplastic polyp, and rapid urease test was positive. Anti-Helicobacter pylori (H. pylori) serum IgG was elevated to 51 U/ml. We performed H. pylori eradication therapy with amoxicillin, clarithromycin and lansoprazole measuring the blood CyA concentration every day. Although the blood CyA concentration reached a peak (the concentration 2 hours after the administration: 818 ng/ml) on the second day, she did not develop renal dysfunction or other obvious adverse effects. Five weeks after the treatment, we confirmed eradication of H. pylori with the urea breath test. We herein reported a case of successful eradication of H. pylori in a LDLT recipient on immunosuppressive therapy with CyA without adverse effects.

RESUMO

Biliary complications, such as stricture or obstruction, after living-donor liver transplantation (LDLT) remain major problems to be solved. Magnetic compression anastomosis (MCA) is a minimally invasive method of biliary anastomosis without surgery in patients with biliary stricture or obstruction. A 66-year-old woman had undergone LDLT for end-stage liver disease for primary biliary cholangitis 20 months previously at another hospital. Computerized tomography showed dilation of the intrahepatic bile duct (B2). Because B2 was invisible with the use of endoscopic retrograde cholangiopancreatography, percutaneous transhepatic biliary drainage (PTBD) was performed for treatment of cholangitis. The rendezvous technique failed because a guidewire could not pass through the biliary stricture. Therefore, we decided to perform MCA. A parent magnet was endoscopically placed distally in the common bile duct of the stricture, and a daughter magnet attached to a guidewire was inserted proximally through the fistula tract of the PTBD. Both magnets were positioned across the stricture, and the 2 magnets were pulled to each other by magnetic power, to sandwich the stricture. By 14 days after MCA, a fistula between B2 and the common bile duct was created. At 28 days after MCA, the magnets were removed distally and a 16-French tube was placed across the fistula. At 7 months after MCA, that tube was removed. In conclusion, when a conventional endoscopic or percutaneous approach including the rendezvous technique fails, MCA is a good technique for biliary stricture after LDLT.

RESUMO

BACKGROUND: Graft regeneration and functional recovery after reperfusion of transplanted graft are very important for successful living donor liver transplantation (LDLT). The aim of this study was to evaluate the significance of postoperative portal venous velocity (PVV) in short-term recovery of graft function in LDLT. PATIENTS AND METHODS: From February 2007 through December 2015, we performed 17 primary LDLTs, which were included in the present study. The patients ranged in age from 12 to 65 years (mean: 50 years), and 11 were female patients. Postoperatively, Doppler ultrasonography was performed daily to measure PVV (cm/s), and liver function parameters were measured daily. The change in PVV (ΔPVV) was defined as follows: ΔPVV = PVV on postoperative day (POD) 1 - PVV on POD 7. Maximal value of serum aspartate aminotransferase (ASTmax) and maximal value of serum alanine transaminase (ALTmax) at 24 hours after graft reperfusion were used as parameters of reperfusion injury. Correlation analyses were performed as follows: (1) correlation of ΔPVV and PVV on POD 1 (PVV-POD 1) with the values such as ASTmax, ALTmax, other liver function parameters on POD 7 and graft regeneration rate; (2) correlation of ASTmax and ALTmax with other liver function parameters on POD 7. RESULTS: ΔPVV significantly correlated with the values of serum total bilirubin (P < .01), prothrombin time (P < .01), and platelet count (P < .05), and PVV-POD 1 significantly correlated with the values of serum total bilirubin (P < .05) and prothrombin time (P < .05). CONCLUSION: ΔPVV and PVV-POD 1 may be useful parameters of short-term functional recovery of the transplant liver in LDLT.

RESUMO

Introduction Radiotherapy is not commonly used for the treatment of gastric cancer in Japan, where surgery is the standard local treatment. We report the results of chemoradiotherapy in patients with advanced or recurrent gastric cancer which was deemed difficult to treat surgically. Methods Twenty-one patients with gastric cancer (including sixteen with advanced/recurrent gastric cancer and five with poor general condition) underwent chemo-radiotherapy, for whom the therapeutic efficacy, toxicity and survival period were analysed. Results The tumour response to chemoradiotherapy was categorised as complete, partial, stable or progressive in 5, 9, 3, and 4 patients, respectively, with an overall response rate of 67%. No serious complications such as gastrointestinal perforation or bleeding occurred, and no cardiac, hepatic or renal dysfunction developed during the follow-up period. The mean survival time was 19.8 months (range, 3-51 months). One patient died of another disease, 18 died of primary cancer and the cause of death was unknown in 2 patients. Conclusions Chemoradiotherapy appears to be an effective treatment for localised gastric cancer without distant metastases, but further studies are needed to determine the indications for chemoradiotherapy and late adverse effects, as well as the chemotherapy regimens to be used.

RESUMO

PURPOSE: The aim of this study was to evaluate the outcome, with a special reference to recurrence and postoperative chronic pain, of the modified Kugel herniorrhaphy (MKH) using standardized dissection of the preperitoneal space. PATIENTS AND METHODS: Operative results were examined based on medical records and questionnaire surveys in 340 consecutive cases of MKH performed at a single institution. The operation was performed with an original 3-stage dissection of the preperitoneal space only via the internal inguinal ring. RESULTS: The mean follow-up period was 50.5 ± 24.3 months. The mean operating time was 42.2 ± 13.1 min, and by Nyhus classification, significant difference was observed between types IIIA and IIIB (39.5 ± 10.8 vs. 45.6 ± 15.6 min, P = 0.0279). Eight surgeons performed 10 or more operations, and no significant difference was found in their operating time. Thirty-one patients used additional analgesics postoperatively (9.1 %) and the length of postoperative stay was 1.2 ± 0.7 days. Seven patients (2.1 %) developed complications related to the hernia operation, but none of them required re-operation. The period required to return to normal daily activities was 3 ± 3.2 days. Questionnaire forms were returned from 77.7 % of all the patients, in which 12 patients reported chronic pain (4.7 %). Visual analog scale for patients with chronic pain scored 3.8 ± 2.4, with no patient indicating restrictions on daily life. Recurrence was observed in only one case (0.3 %). CONCLUSION: MKH using standardized dissection of the preperitoneal space is a highly reproducible procedure with acceptable rate of postoperative chronic pain and recurrence.

RESUMO

To date, only limited cases of Diego blood group disparity in liver transplantation have been reported, and no cases with a long-term clinical course have been documented. Herein, we report a case of Diego blood group disparity in liver transplantation with details of long-term follow-up. The recipient was a 47-year-old woman with primary biliary cirrhosis; her 18-year-old daughter was the donor. Both recipient and donor were of blood type O according to the ABO blood group system. Preoperative serological tests showed the presence of antibodies against the Di(a) antigen only in the recipient, and not in the donor. Thus, the Diego phenotype was Di(a+) in the donor and Di(a-) in the recipient. Living-related liver transplantation was performed in July 2009. Immediate graft function was obtained, and no signs of humoral or cellular rejection were observed during the postoperative period. Further, anti-Di(a) antibodies were not detected throughout the postoperative course. The patient is alive and shows no signs of humoral rejection 34 months after liver transplantation. Liver transplantation has been performed successfully in cases of Diego blood group disparity.

RESUMO

The etiology of achalasia is believed to be the neuropathy associated with chronic inflammation of the nerve plexus, but the cause of plexus inflammation is unknown. The purpose of this study was to evaluate the pathophysiology of achalasia by examining the muscularis externa of the esophagus. We used the muscularis externa of the esophagus of 62 patients with achalasia (median 44 years, male : female 32:30) who underwent surgical treatment (achalasia group) and of 10 patients (median 65.5 years, male : female 9:1) who underwent esophagectomy for thoracic esophageal cancer (control group) to perform immunohistochemical staining with S-100, CD43, c-kit (CD117), n-NOS, vasoactive intestinal polypeptide (VIP), and ubiquitin. The cell counts that were positive for S-100, n-NOS, VIP, and ubiquitin were significantly lower in the achalasia group compared with the control group (P < 0.001, P= 0.001, P < 0.001, and P= 0.001, respectively). There were no statistically significant differences with respect to CD43 and c-kit staining (P= 0.586 and P= 0.209, respectively). In conclusion, the pathophysiology of achalasia is therefore considered to be an impaired production of NO and VIP, which both affect interstitial cell of Cajal and smooth muscles, and this impairment is therefore considered to play a role in the pathophysiology of achalasia.

RESUMO

AIM: This study compares lymphatic mapping in early gastric cancer with ICG and infrared ray electronic endoscopy (IREE) to ICG alone. It examines the optimal method for intra-operative detection of metastases and shows long term follow up results. METHODS: 212 patients underwent the SN procedure with IREE and peritumoural ICG injection. Evaluated parameters were detection of sentinel nodes with IREE versus ICG alone, intra-operative detection rate of lymph node (LN) metastasis with node picking versus lymphatic basin dissection (LBD) and lymphatic drainage patterns. RESULTS: 34 patients had LN metastases. The SN identification rate and sensitivity for IREE versus ICG alone were 99.5 versus 85.8% and 97.0 versus 48.4% respectively. Intra-operative accuracy for detecting LN metastasis was 50% with node picking versus 92.3% with LBD. LN metastases were always in the SN basin. Lymphatic invasion and T-stage were risk factors for nodal metastases. Two patients showed recurrent disease. Both had a tumour with signet cell differentiation. One patient had a T3 tumour, the other patient had a tumour with a diameter of 85 mm. CONCLUSION: The SN procedure with IREE can detect the SN and is better than ICG alone. LBD of the SN basin is required for accurate intra-operative diagnosis of metastases. LBD dissection based on IREE is a safe method of nodal dissection in patients with T1 or limited T2 tumours.

RESUMO

BACKGROUND: The primary end points of this study were to determine the dose-limiting toxic effects (DLTs), maximum tolerated dose, and a recommended phase II dose of a synthetic serine protease inhibitor, nafamostat mesilate, in combination with full-dose gemcitabine in patients with unresectable locally advanced or metastatic pancreatic cancer. The secondary end point was to assess therapeutic response. PATIENTS AND METHODS: Patients with previously untreated pancreatic cancer received gemcitabine (1 000 mg/m(2) i.v. for 30 min) on days 1, 8, and 15, with nafamostat mesilate (continuous regional arterial infusion for 24 h through a port-catheter system) on days 1, 8, and 15; this regimen was repeated at 28-day intervals. The initial dose of nafamostat mesilate was 2.4 mg/kg and was escalated in increments of 1.2 mg/kg until a dose of 4.8 mg/kg was achieved. A standard '3+3' phase I dose-escalation design was used. Therapeutic response and clinical benefit response were assessed. RESULTS: Twelve patients were enrolled in this study. None of the patients experienced DLTs, and nafamostat mesilate was well tolerated at doses up to 4.8 mg/kg in combination with full-dose gemcitabine. This combination chemotherapy yielded a reduction of a high serum level of the tumor marker CA19-9. Pain was reduced in three of seven patients without oral morphine sulfate. Overall survival was 7.1 months for all patients. CONCLUSION: This phase I study was carried out safely. This combination chemotherapy showed beneficial improvement in health-related quality of life. The recommended phase II dose of nafamostat mesilate in combination with full-dose gemcitabine is 4.8 mg/kg.

RESUMO

Mitotic centromere-associated kinesin (MCAK) is a microtubule (MT) depolymerase necessary for ensuring proper kinetochore MT attachment during spindle formation. To determine MCAK expression status and its clinicopathological significance, real-time reverse transcriptase-polymerase chain reaction was used in 65 cases of gastric cancer. MCAK gene expression in cancer tissue was significantly higher than expression in non-malignant tissue (P<0.05). Elevated MCAK expression was significantly associated with lymphatic invasion (P=0.01) and lymph node metastasis (P=0.04). Furthermore, patients with high MCAK expression had a significantly poorer survival rate than those with low MCAK expression (P=0.008). Immunohistochemical study revealed that expression of MCAK was primarily observed in cancer cells. Additionally, a gastric cancer cell line (AZ521) that stably expressed MCAK was established and used to investigate the biological effects of the MCAK gene. In vitro results showed that cells transfected with MCAK had a high rate of proliferation (P<0.001) and increased migratory ability (P<0.001) compared to mock-transfected cells. This study demonstrated that elevated expression of MCAK may be associated with lymphatic invasion, lymph node metastasis, and poor prognosis. These characteristics may be due in part to the increased proliferative and migratory ability of cells expressing MCAK.

RESUMO

BACKGROUND: An aberrant left hepatic artery (ALHA) is occasionally encountered during esophagogastric surgery. However, at curative gastrectomy for gastric cancer, it is questionable as to whether the ALHA need to be divided in order to maximize lymph node clearance and the issue requires clarification. METHODS: We encountered 50 patients with an ALHA during curative gastrectomy for gastric cancer between 1997 and 2001. Data concerning operative feasibility, postoperative liver function and therapeutic value of nodal dissection were analyzed retrospectively. RESULTS: For 27 patients, we preserved the ALHA, and for the remaining 23 patients, we divided the ALHA at the origin of the left gastric artery (LGA). Serum levels of aspartate aminotransferase and alanine aminotransferase were statistically significant higher on postoperative day (POD) 1 (P=0.0008 and P=0.0007), and on POD 3 (P=0.001 and P=0.008), respectively, in the ALHA-divided group. Patients who underwent a total gastrectomy predominated in the ALHA-divided group, the total number of dissected lymph nodes being higher in the ALHA-divided group (P=0.018). However, the total numbers of dissected lymph nodes and metastatic lymph nodes around the LGA were similar in the 2 groups (P=0.447 and P=0.128), respectively. No significant differences were seen between the 2 groups in morbidity and mortality. The overall 5-year survival rates were also comparable. CONCLUSIONS: Although a prospective study is required, this study suggested that routine division of the ALHA may not always be required for curative gastrectomy.

RESUMO

BACKGROUND: The aim of this study was to validate a novel imaging system that uses ATX-S10Na(II) to detect sentinel nodes (SNs) in gastric cancer. The new technique was compared with the enhanced visualization method using indocyanine green (ICG). METHODS: Human gastric carcinoma cells were implanted orthotopically into 50 nude rats, which were divided into two groups. In the first group (n = 25), ATX-S10Na(II) was injected subserosally into the implanted site and visualized by a fluorescence spectrolaparoscope. In the second group (n = 25), ICG was similarly injected and observed through a near-infrared laparoscope. The presence of metastatic tumour cells was determined by reverse transcriptase-polymerase chain reaction specific for human beta-actin. RESULTS: ATX-S10Na(II) was clearly identified as a bright red colour, and was rapidly incorporated into the lymphatic system. Detection rates of SNs were 100 (95 per cent confidence interval (c.i.) 52 to 100) per cent (25 of 25) for ATX-S10Na(II) and 95 (95 per cent c.i. 40 to 100) per cent (21 of 22) for ICG. Sensitivity was 96 (95 per cent c.i. 45 to 100) and 81 (95 per cent c.i. 58 to 95) per cent respectively. CONCLUSION: These results support the validity of the ATX-S10Na(II)-guided approach in the detection of SNs in gastric cancer in vivo.

RESUMO

BACKGROUND: The usefulness of the anatomy-function-pathology (AFP) score was examined to evaluate its prediction of recurrence after laparoscopic fundoplication for erosive reflux esophagitis. METHODS: Of the patients undergoing laparoscopic fundoplication for erosive reflux esophagitis of Los Angeles classification grade A or higher from December 1994 to December 2004, 107 who underwent preoperative barium esophagogram, pH monitoring, and endoscopy were selected as subjects. The AFP score was calculated by A, F, and P factor grades of the AFP classification. By comparing patients with and without recurrence, the usefulness of the AFP score for predicting recurrence was examined. RESULTS: Reflux esophagitis recurred in seven patients. No significant difference in age, sex, or A or F factor was observed between the groups, whereas a significant difference was observed in the P factor (p = 0.008). On the other hand, the mean AFP score in the recurrence group was 16.9 +/- 5.3, whereas that in the nonrecurrence group was 8.9 +/- 5.3 (p = 0.0021). Among the patients with a score of 17 points or more (n = 23), recurrence was found in 6 patients (26%). On the other hand, among the patients with a score lower than 17 points (n = 84), recurrence was found in 1 patient, but not in the remaining 83 patients (1%). Sensitivity was thus 85.7% (95% confidence interval [CI], 42.1-99.6), and specificity was 83% (95% CI, 74.2-89.8). The positive predictive value was 26.1% (95% CI, 10.2-48.4), and the negative predictive value was 98.8% (95% CI, 93.5-99.9). Multiple logistic regression analysis was performed, and receiver operating characteristics curves were obtained. The area under the curve for the AFP score was 0.8457, whereas that for the P factor was 0.7907 (p = 0.0045), suggesting that the AFP score may more accurately predict recurrence than the P factor. CONCLUSION: The AFP score may be useful for predicting postoperative recurrence. If surgery is performed when the AFP score is lower than 17 points, the likelihood of postoperative recurrence is expected to be very low.

RESUMO

BACKGROUND: Reflux oesophagitis is commonly encountered in the surgical treatment of cancer of the upper third of the stomach. The aim of this study was to describe a novel surgical technique and evaluate the clinical outcome of high segmental gastrectomy for early-stage proximal gastric cancer. METHODS: Thirty consecutive patients with early gastric cancer located in the upper third of the stomach were included, of whom 12 underwent high segmental gastrectomy and 18 underwent proximal gastrectomy with jejunal interposition. The incidence of reflux oesophagitis and nutritional parameters were compared between the two groups at 1 year after operation. RESULTS: One patient had mild reflux symptoms and two had endoscopic evidence of oesophagitis 1 year after high segmental gastrectomy. Half of the patients who had proximal gastrectomy had reflux symptoms of varying severity and 14 had endoscopic evidence of oesophageal changes at 1 year after surgery. There were significant differences between groups in the incidence of reflux symptoms (P = 0.016) and endoscopically detected gastro-oesophagitis (P < 0.001). There were no adverse events in either group, and the survival rate after high segmental gastrectomy appeared favourable. CONCLUSION: Selected patients with early-stage proximal gastric cancer benefit from high segmental gastrectomy in terms of reduced reflex oesophagitis, without jeopardizing curability.

RESUMO

AIM: To assess the risk of gastric cancer in a Japanese patient population with the disease by stratification with histology, age, tumour location and the association with family history of gastric or non-gastric tumours. METHODS: A retrospective analysis of 1400 consecutive patients with gastric cancer and 13,467 age- and gender-matched controls from a pre-recorded database using conditional logistic regression models. RESULTS: Young patients (< or = 43 years of age) with gastric cancer of intestinal type had a strong association with family history of gastric cancer in first degree-relatives (OR=12.5). Moreover, when a history of gastric cancer was observed in both parents, there was an increased risk of gastric cancer intestinal type (OR=7.8), more commonly in the proximal and mid-stomach. In contrast, there was an increased risk of diffuse-type cancer when both parents suffered non-gastric cancers (OR=2.1). CONCLUSION: These data suggest that the degree of familial clustering differ in gastric cancer subgroups stratified by histology, age, and stomach location in this Japanese population.

RESUMO

BACKGROUND: The significance of laparoscopic Heller myotomy and Dor fundoplication (LHD) for the treatment of achalasia in relation to the severity of the lesion has not been sufficiently assessed. METHODS: Of patients who were diagnosed with achalasia from August 1994 to February 2004, 55 individuals who underwent LHD served as subjects. The therapeutic effects of LHD were assessed in terms of operation time, intraoperative complications, postoperative hospital stay, and symptom improvement in relation to morphologic type (spindle type, Sp; flask type, Fk; and sigmoid type, Sig). Degree of symptomatic improvement was classified into four grades: excellent, good, fair, and poor. RESULTS: Breakdown of morphologic type was as follows: Sp, n = 29; Fk, n = 18; and Sig, n = 8. Excluding one patient for whom conversion to open surgery was required, median average operation time for 54 patients was 160 min. As to intraoperative complications, esophageal mucosal perforation was seen in nine of the 55 patients (16%); however, conversion to open surgery could be avoided by suturing the affected area. Moreover, intraoperative bleeding of at least 100 g was seen in five of the 55 patients (9%), with one Fk patient requiring conversion to open surgery and transfusion. Median postoperative hospital stay was 8 days. Degree of dysphagia relief was excellent in 45 patients (83%), good in eight patients (15%), and fair in one patient (2%). Excellent improvement was obtained in 90%, 88%, and 50% in Sp, Fk, and Sig patients, respectively. Reflux esophagitis was seen in two patients, and was treated with a proton pump inhibitor. CONCLUSIONS: The results of the present study suggest that classification of morphologic type is a useful parameter in predicting postoperative outcome in achalasia. In order to achieve excellent symptomatic relief, surgery for achalasia should be recommended for but not limited to Sp and Fk types.

RESUMO

AIM: To prove the feasibility of hand-assisted laparoscopic and thoracoscopic surgery (HALTS) for radical esophagectomy with three-field lymphadenectomy to thoracic esophageal cancer. METHODS: Esophagectomy with three-field lymphadenectomy was performed using HALTS in 19 patients with thoracic esophageal cancer without distant metastasis. Five patients had chemo-radiotherapy prior to surgery. RESULTS: All operations were completed successfully without the need for open surgery. Mean surgical time was 476+/-58 min, and mean blood loss during surgery was 343+/-184 mL. All patients started tube feeding and were moved from the intensive care unit to the general surgery ward the day after surgery. Discharge occurred a median of 10 days after surgery. Fifteen patients could return to full time jobs from 8 to 62 days after surgery (median 22 days) and from 1 to 35 days after discharge (median 9 days). Other three could return to daily activities at home soon as well. No major complications occurred, except one anastomotic leak. In terms of lung function, %FEV(1) was not changed whereas %VC was reduced significantly 1 month after surgery. All but two recurrences have been healthy without a relapse for a mean of 289 days. CONCLUSIONS: These results suggest that HALTS may be a useful surgical technique to reduce the invasiveness of conventional radical esophagectomy with three-field lymphadenectomy for thoracic esophageal cancer.

RESUMO

The authors objective was to determine the toxicities and maximum tolerated dose of a dose-dense schedule of fixed-dose paclitaxel and escalating doses of cisplatin in patients with recurrent or unresectable carcinoma of the stomach. On days 1, 8, 15, 29, 36, and 43, patients received a fixed dose of paclitaxel (80 mg/m2 over 1 hour after a short premedication) followed by a 30-minute infusion of cisplatin at dose levels of 7, 15, 20, and 25 mg/m2. Six patients were treated at each dose level, except for the dose of 25 mg/m2 cisplatin. All the patients were assessed for toxicity and 17 patients (81%) were evaluated for response. The cisplatin dose could be escalated to 25 mg/m2. At the dose of 80 mg/m2 paclitaxel and 25 mg/m2 cisplatin, all 3 patients developed dose-limiting toxicity of the gastrointestinal tract. There were no treatment-related deaths. Leukopenia grades 3 or 4 was seen in 5 patients (11.1%), but infectious complications were not encountered. Other toxicities were mild and easily managed. Weekly paclitaxel at a dose of 80 mg/m2 infused over 1 hour, followed by an infusion of 20 mg/m2 cisplatin is recommended for further study in patients with recurrent or unresectable gastric cancer.
