RESUMO
PURPOSE: To determine whether frequent measurement of tumor markers triggers early detection of colorectal cancer recurrence. METHODS: Of 1,651 consecutive patients undergoing colorectal cancer surgery between 2010 and 2016, 1,050 were included. CEA and CA 19-9 were considered to be postoperative tumor markers and were measured every 3 months for 3 years, and then every 6 months for 2 years. Sensitivity analysis of elevated CEA and CA19-9 levels and multivariate analysis of factors associated with elevated CEA and CA19-9 levels were performed. The proportion of triggers for detecting recurrence was determined. RESULTS: The median follow-up period was 5.3 years. After applying the exclusion criteria, 1,050 patients were analyzed, 176 (16.8%) of whom were found to have recurrence. After excluding patients with persistently elevated CEA and CA19-9 levels before and after surgery from the 176 patients, 71 (43.6%) of 163 patients had elevated CEA levels and 35 (20.2%) of 173 patients had elevated CA19-9 levels. Sensitivity/positive predictive values for elevated CEA and CA19-9 levels at recurrence were 43.6%/32.3% and 20.2%/32.4%, respectively. Lymph node metastasis was a factor associated with both elevated CEA and CA19-9 levels at recurrence. Of the 176 patients, computed tomography triggered the detection of recurrence in 137 (78%) and elevated tumor marker levels in 13 (7%); the diagnostic lead interval in the latter 13 patients was 1.7 months. CONCLUSION: Tumor marker measurements in surveillance after radical colorectal cancer resection contribute little to early detection, and frequent measurements are unnecessary for stage I patients with low risk of recurrence.

PURPOSE: To clarify how often postoperative surveillance colonoscopy should be undertaken based on the risk factors for the development of metachronous cancer (MC) and advanced adenoma (AA) after surgery for colorectal cancer. METHODS: We collected data of consecutive patients who underwent curative resection for primary colorectal cancer between 2005 and 2012, with preoperative colonoscopy and surveillance colonoscopy at 1 year after surgery (406 patients, mean age: 69 years, 59% male). The detection rates of AA (with villous features, > 10 mm or high-grade dysplasia) and MC by surveillance colonoscopy were the primary outcomes. RESULTS: At 5 years, colonoscopy was performed as postoperative surveillance an average of 3.2 times. AA and MC were detected in 57 (14.0%) and 18 patients (4.4%), respectively. Both lesions were more common in the right colon (n = 43) than in the left colon (n = 28). The detection rate did not differ to a statistically significant extent according to the number of colonoscopies performed for surveillance (p = 0.21). However, after left-sided colectomy, both types of lesions were more commonly detected in those who received ≥ 3 colonoscopies than in those with one or two colonoscopies (p = 0.04). CONCLUSION: A remaining right colon after left-sided colectomy was associated with a higher risk of developing AA and MC. Physicians should consider performing surveillance colonoscopy more frequently if the right colon remains after surgery.

A 67-year-old man presented with abdominal distention and vomiting.Computed tomography revealed bowel obstruction due to a cecal tumor.We performed laparoscopic ileocecal resection after decompression with an ileus tube. Intraoperative findings included multiple disseminated nodules on the mesenterium surrounding the cecal tumor.The histopathologic diagnosis was poorly differentiated adenocarcinoma, which consisted of glandular proliferation of atypical epithelial cells and dispersed infiltration of goblet cells. Immunohistochemistry showed positively stained neuroendocrine markers, such as CD56, chromogranin, and synaptophysin.The patient was diagnosed with goblet cell carcinoid of the appendix and treated with combination chemotherapy of bevacizumab, fluorouracil, folinic acid, and oxaliplatin.He remained free from progression for over 1 and half years with this treatment.Subsequent chemotherapy was ineffective, and he passed away.There is no established chemotherapy regimen for goblet cell carcinoid, which has the aspects of both adenocarcinoma and neuroendocrine tumors.However, the present case suggested the efficacy of the mFOLFOX6 regimen in combination with bevacizumab for appendiceal goblet cell carcinoid.

A 74-year-old man visited his local clinic complaining of abdominal pain that persisted for three days. He was diagnosed with diffuse peritonitis and was transported to our hospital. Contrast computed tomography(CT)showed gastric perforation and a tumor in the sigmoid colon with left obturator lymph node metastasis. He was diagnosed with diffuse peritonitis resulting from gastric perforation and performed emergent surgery. As the size of the gastric perforation was large, we performed distal gastrectomy and transverse colostomy. He was discharged without any complications, and a total of 6 courses of SOX with a bevacizumab regimen were administered postoperatively. CT following chemotherapy showed shrinkage of the lesion. He was admitted again for sigmoidectomy with left lateral lymph node resection and discharged from the hospital on postoperative day 8. We administered 2 courses of SOX regimen after the surgery. He remains alive with no recurrence 27months after the first surgery.

BACKGROUND: Repeat hepatectomy is often required for hepatocellular carcinoma and metastatic tumors. However, this procedure is technically challenging, so laparoscopic repeat hepatectomy (LRH) has not been widely adopted. The aim of this study was to evaluate the feasibility and efficacy of LRH compared with open repeat hepatectomy (ORH) and laparoscopic primary hepatectomy (LPH). METHODS: We introduced laparoscopic hepatectomy at our institution in April 2014. We performed 127 LPH (LPH group) and 33 LRH procedures (LRH group) from April 2014 to April 2017; 37 patients underwent ORH from January 2010 to April 2017 (ORH group). This study retrospectively compared the patient characteristics and short-term outcomes of the LRH and ORH groups as well as the LRH and LPH groups. RESULTS: There were no conversions to open surgery in the LRH group. In comparing the LRH and ORH groups, there were no significant differences in patient characteristics except for the type of approach to the previous hepatectomy (p = 0.004) and indocyanine green retention rate at 15 min (median 12.5 vs. 8.75%, p = 0.026). The LRH group had less blood loss (median 30 mL vs. 652 mL; p < 0.001), less intraoperative transfusion (6.1 vs. 32.4%; p = 0.006), and shorter postoperative hospital stays (median 6.5 days vs. 9.0 days; p < 0.001). There were no differences with regard to operation time, severe postoperative complications, and mortality. In comparing the LRH and LPH groups, there was a significant difference only in past history of abdominal surgery (100 vs. 61.4%; p < 0.001). In the short-term outcomes, the postoperative hospital stay was significantly shorter in the LRH group (median 6.5 days vs. 7 days; p = 0.033), and the other results were comparable between the two groups. CONCLUSIONS: LRH is feasible and useful for repeat hepatectomy, achieving good short-term outcomes.

PURPOSE: In Japan, transabdominal preperitoneal (TAPP) inguinal hernia repair is performed by firmly pulling the peritoneum inwards to lift it from the underlying deep layer of subperitoneal fascia. It decreases the postoperative pain and discomfort in the inguinal area. The aim of this study was to evaluate the feasibility of the sandwich approach, which is a new technique for creating a preperitoneal space. METHODS: The operation was performed via the sandwich approach. We made sure to protect the preperitoneal fascia areolar layer when making the preperitoneal space. RESULTS: We performed TAPP in 745 patients (876 hernias) treated between October 2006 and April 2015 at Himeji Medical Center and Kurashiki Central Hospital. Before October 2010, we did not use the sandwich approach, and recurrence was observed in three patients. From October 2010, we always used the sandwich approach and never experienced any cases of recurrence. Clavien-Dindo classification Grade 3 or higher postoperative complications occurred in 6 patients (0.8%) between October 2006 and April 2015. Mesh-related ileus was the most frequently observed morbidity. There were no cases of vas differentia or spermatic vessel injury, postoperative chronic pain, or urinary retention. CONCLUSION: The sandwich approach is feasible as another standard dissective procedure for TAPP.

A 72-year-old woman was admitted to our hospital because of muscle weakness and was diagnosed as having polymyositis. Whole-body evaluation revealed advanced transverse colon cancer, and we therefore considered it likely that the patient had paraneoplastic myositis. We performed a curative surgical resection for colon cancer, after which her serum creatine phosphokinase(CPK)level greatly decreased. Steroid therapy was administered postoperatively. However, her CPK levels remained persistently high, even after steroid pulse therapy, and we considered that this was due to steroid-resistance myositis. We administered chemotherapy for colon cancer using 5-fluorouracil plus Leucovorin(5-FU/LV), after which the CPK levels gradually decreased. There have been few previous reports of polymyositis associated with colon cancer and a standard treatment for paraneoplastic myositis has not been established. Most clinicians believe that treatment of the primary tumor may contribute to an improvement of myositis, and in our case, tumor resection and chemotherapy were effective.

We report a 37-year-old woman who complained of chest discomfort as of August 2004, and was found to have advanced esophageal cancer in the upper thoracic area in December 2004.S he was diagnosed as Stage IVa (T4N1M0) because chest computed tomography (CT) indicated trachea invasion and lymph node metastasis. We diagnosed it to be a case of unresectable esophageal cancer, and she underwent chemoradiation therapy. CT showed regression of the main tumor and metastatic lymph nodes when the CRT course was completed. The main tumor disappeared macroscopically. We again considered an operation, but the CRT was so effective that the patient wished to continue CRT and underwent three courses. Endoscopy showed disappearance of the main tumor and Lugol's solution. Following this, 10 courses of the treatment with CDDP alone (CDDP 10 mg/weekly) were continued until the appearance of renal dysfunction. S-1 (100 mg/body/day)was started in September 2005. The treatment is currently ongoing, and no recurrence or metastases had occurred as of March 2009.

BACKGROUND: The efficacy of S-1 plus oxaliplatin (SOX) as postoperative adjuvant chemotherapy for colon cancer has not been established. This randomized phase III study was designed to verify the superiority of SOX over tegafur-uracil and leucovorin (UFT/LV) in patients with high-risk stage III colon cancer (any T, N2, or positive nodes around the origin of the feeding arteries). PATIENTS AND METHODS: Patients who underwent curative resection for pathologically confirmed high-risk stage III colon cancer were randomly assigned to receive either UFT/LV (300 mg/m2 of UFT and 75 mg/day of LV on days 1-28, every 35 days, 5 cycles) or SOX (100 mg/m2 of oxaliplatin on day 1 and 80 mg/m2 of S-1 on days 1-14, every 21 days, 8 cycles). The primary endpoint was disease-free survival (DFS). RESULTS: A total of 478 patients in the UFT/LV group and 477 patients in the SOX group were included in the primary analysis. The 3-year DFS was 60.6% (95% confidence interval [CI], 56.0%-64.9%) in the UFT/LV group and 62.7% (95% CI, 58.1%-66.9%) in the SOX group. The stratified hazard ratio for DFS was 0.90 (95% CI, 0.74-1.09; stratified log-rank test, P = .2780). In the N2b subgroup, the 3-year DFS was 46.0% (95% CI, 37.5%-54.0%) in the UFT/LV group and 54.7% (95% CI, 45.7%-62.7%) in the SOX group (hazard ratio, 0.76; 95% CI, 0.55-1.05). CONCLUSION: As postoperative adjuvant chemotherapy, SOX was not superior to UFT/LV in terms of DFS in patients with high-risk stage III colon cancer.

The patient was a 54-year-old male. In July 2004, he underwent resection of the pancreatic body tail region to treat pancreatic body tail cancer. On histopathological examination, the stump of the extirpated specimen was positive for tumor cells. After surgery, 10 courses of therapy with gemcitabine hydrochloride(GEM, 1, 000 mg/m(2), 3-week administration followed by 1-week discontinuation)were performed, and follow-up was continued. In February 2006, local relapse was detected. Chemotherapy with GEM was administered for 1 year and 9 months. However, in November 2007, an increase in the recurrent lesion size and right lung metastasis were noted. The regimen was switched to combination therapy with S-1 and GEM(S-1 60 mg/m(2) day, continuous administration on days 1 to 14 and 2-week discontinuation; and GEM 1, 000 mg/ m(2), administered on days 8 and 15). After the end of the 11th course, PET-CT revealed the disappearance of FDG accumulation in the recurrent and metastatic lesion sites. During the treatment period, there were no grade 3 or higher adverse reactions. The patient is being treated at the outpatient clinic (as of January 2009).

BACKGROUND: Obesity is generally reported to increase the risk of surgical complications. There have been few reports of laparoscopic hepatectomy (LH) in obese patients. The purpose of this study was to compare the safety and efficacy of (1) LH versus open hepatectomy (OH) in obese patients and (2) LH in obese patients versus LH in non-obese patients. METHODS: We introduced LH at our institution in April 2014. LH was performed in 63 obese patients and 108 non-obese patients from April 2014 to May 2017. OH was performed in 79 obese patients from January 2010 to May 2017. This study retrospectively compared the short-term outcomes of the LH obese group with those of the OH obese group and the LH non-obese group. RESULTS: In patient characteristics, the LH obese group included a significantly higher percentage of patients with liver cirrhosis than the OH obese group. The LH obese group had fewer patients with a history of abdominal surgery but more with liver cirrhosis than the LH non-obese group. For short-term outcomes, the LH obese group had significantly less blood loss, fewer intraoperative transfusions, fewer positive surgical margins, and shorter postoperative hospital stays than the OH obese group. In contrast, only operation time was significantly different (longer) in the LH obese group than in the LH non-obese group. There were no significant differences in morbidity or mortality between the LH obese group and either the OH obese or the LH non-obese groups. CONCLUSION: LH in obese patients is safe and effective.

PURPOSES: Seroma is a postoperative complication following laparoscopic transabdominal preperitoneal repair (TAPP) for inguinal hernioplasty. Seroma naturally resolves in most cases, but it can lead to an increased amount of visits to the outpatient clinic and can result in anxiety of the patient. Local inflammation of the inguinal area is etiology of seroma formation. Strangulated hernia involves severe inguinal pain and can lead to severe inflammation and subsequent seroma. There have been no reports demonstrating the links of seroma and strangulated hernia. This study aimed to retrospectively evaluate the risk of seroma after TAPP and to identify the association between strangulated hernia and seroma. METHODS: We treated 300 inguinal hernias by TAPP between 2013 and 2016 at Kurashiki Central Hospital. We used the Chi-square test. Factors significant in each association were further examined using multiple subsequent logistic regressions. RESULTS: A total of 222 hernias were eligible for analysis. The incidence of seroma was 11% (n=25). There were nine cases of strangulated hernias, and three (33%) resulted in seroma. The ratio of strangulated hernia of seroma group is significantly high (p<0.03). Multiple subsequent logistic regressions showed that strangulated hernia was associated with a significantly increased risk for seroma formation (p = 0.023; OR 6.564; 95% CI 1.29-33.3). CONCLUSION: This study shows that strangulated hernia can be a risk factor in seroma formation. This risk should be incorporated into a management plan of TAPP for strangulated hernia, with careful consideration of patients' concerns.
RESUMO
INTRODUCTION: Postoperative chronic pain is an important outcome of hernia surgery. In laparoscopic hernia surgery, either fixation outside the trapezoid of disaster or no fixation is recommended to avoid postoperative pain. To avoid recurrence are transabdominal preperitoneal (TAPP) hernia repair, the myopectineal orifice must be covered with mesh during TAPP, but lifting or shrinking of the mesh can lead to recurrence. The aim of this study was to evaluate the feasibility of a novel technique for mesh fixation to prevent the mesh from lifting off. METHODS: After the preperitoneal space was created during TAPP, the anatomy of the lateral cutaneous nerve of the thigh or the femoral branch of the genitofemoral nerve within the trapezoid of disaster was checked. The mesh was tacked at the trapezoid of disaster without nerve injury, and the mesh was fixed with circumferential tacking. We call this procedure secure tacking against recurrence (STAR). We treated 391 adult patients (478 hernias) with TAPP repair; novel tacking was used in some patients (STAR group, 236 hernias). The results of the STAR group were retrospectively compared with those of patients in whom we did not use this novel tacking (conventional group, 242 hernias). RESULTS: There was no postoperative chronic pain in either group. There were no cases of hernia recurrence in the STAR group, but there were four cases of hernia recurrence in the conventional group (0% vs 1.7%, P = 0.047). These four recurrences consisted of indirect hernia and mesh lifting on the lateral side. CONCLUSION: The STAR procedure is feasible and safety as a standard procedure for securing the mesh during TAPP.

BACKGROUND: This trial was designed to verify the superiority of 6 months of postoperative adjuvant chemotherapy with SOX (S-1 with oxaliplatin) with UFT (tegafur and uracil) with LV (leucovorin) in terms of disease-free survival in patients with high-risk stage III colon cancer. We report the results of a planned safety analysis. PATIENTS AND METHODS: Patients who underwent curative resection for high-risk stage III colon cancer (any T, N2, or positive nodes around the origin of the feeding arteries) were randomly assigned to receive either UFT/LV (300-600 mg/d UFT with 75 mg/d LV on days 1-28, every 35 days, for 5 cycles) or SOX (100 mg/m2 of oxaliplatin on day 1 with 80-120 mg/d S-1 on days 1-14, every 21 days, for 8 cycles). Treatment status and safety were evaluated. RESULTS: A total of 966 patients were enrolled, and 932 patients were included in safety analyses. The planned 6-month protocol treatment was received by 76.9% of the patients in the UFT/LV group and 65.8% of those in the SOX group. The overall incidence of any Grade adverse events (AEs) were 91.3% in the UFT/LV group and 98.7% in the SOX group, and those of Grade ≥ 3 AEs were 16.1% and 36.1%, respectively. As for Grade ≥ 3 AEs, leukopenia, neutropenia, thrombocytopenia, and sensory neuropathy were more common in the SOX group. The incidence of Grade ≥ 3 sensory peripheral neuropathy was 4.6% in the SOX group. CONCLUSION: The completion rate of adjuvant SOX and its incidence of AEs were acceptable in patients with colon cancer.

In February, 19 9 8, a 48-year-old female patient underwent an operation for breast cancer. In November 2003, abdominal MRI revealed metastatic lesions in S 3 and S 5 of the liver, and chemotherapy (trastuzumab+weekly paclitaxel) was started, after which the metastatic lesions quickly reduced in size. No lesions could be detected by April 2004, and she was diagnosed as a complete response (CR). She now visits our hospital as an outpatient without any evidence of recurrence or any side effects of chemotherapy for 8 years and 8 months after surgery. For advanced breast cancer, there is no standard criteria regarding the time when to stop chemotherapy after obtaining a CR. This time, we experienced a case of liver metastasis of breast cancer responding to a regimen of trastuzumab plus weekly paclitaxel chemotherapy maintaining CR for a long period. We discuss the timing of the termination of chemotherapy in such a case in light of our experience and the literature.

A 73-year-old woman underwent chemotherapy, radiotherapy, and hormonal therapies for right advanced breast cancer (T4, N3, M1, Stage IV) in 1993. She obtained a complete response in pathological evaluation (pCR) in 1998. For adjuvant therapies, she had been treated with hormonal therapies for five years until 2003. After the interruption of hormonal therapies, the serum levels of tumor markers had been elevated, and she had a right axillary local recurrence and a right ovarian metastasis detected by a FDG-PET/CT in February 2006. The right axillary local recurrence lesion was then resected, and she has since been treated with hormonal therapy of aromatase inhibitor (AI). The serum levels of tumor markers have been remarkably reduced, and FDG-PET/CT has showed the disappearance of the right axillary local recurrence, and the decrease of FDG accumulation of the right ovarian metastases in February 2007. We present a case of non-operated advanced breast cancer with local recurrence surviving successfully long term when treated with AI.

The patient was a 61-year-old man who suffered from advanced gastric cancer, and a distal gastrectomy was performed (T3N2P1CY1, Stage IV). He was treated with chemotherapy of TS-1 alone (100 mg/day, days 1-28 with two weeks rest). Six months later he complained of lumbago and appetite loss, then was admitted to the hospital with obstructive jaundice. Total bilirubin (T-Bil) was increased to 11.3 mg/dl. CT scan examination revealed peritoneal dissemination with much ascites and dilatation of intrahepatic bile ducts. Endoscopic drainage was tried, but was discontinued due to stenosis of gastroduodenal anastomosis. Ultimately, T-Bil was elevated to 25.2 mg/dl, and he could not sleep comfortably because of a severe itch and an irritating feeling. Weekly paclitaxel therapy was started (70 mg/m(2), day 1, 8, 15, once a week for 3 weeks followed by a week rest as one cycle). One month after the first infusion therapy, the obstructive jaundice was notably improved and the ascites disappeared completely, so he was discharged. For about one year, he was treated with this chemotherapy as an outpatient. The toxic events were anemia (grade 3) and alopecia (grade 1).

The patient was a 63-year-old man who suffered from advanced pancreatic cancer (T 4 N 3 M 0, Stage IVb). Palliative operation was performed for obstructive jaundice. He was treated with chemotherapy of gemcitabine (GEM) alone as first-line, and combined chemotherapy of GEM and S-1 as second-line. Both therapies were effective for this patient. Tumor marker (CA 19-9) decreased after chemotherapies (first-line: 5,692 U/mL to 70 U/mL, second-line: 4,877 U/mL to 562 U/mL). No toxic events were observed due to these therapies, so he was treated as an outpatient for about 2 years. It was considered that he had a good quality of life.

AIM: To evaluate a laparoscopic approach to gallbladder lesions including polyps, wall-thickening lesions, and suspected T1 and T2 gallbladder cancer (GBC). METHODS: We performed 50 cases of laparoscopic whole-layer cholecystectomy (LCWL) and 13 cases of laparoscopic gallbladder bed resection (LCGB) for those gallbladder lesions from April 2010 to November 2016. We analyzed the short-term and long-term results of our laparoscopic approach. RESULTS: The median operation time was 108 min for LCWL and 211 min for LCGB. The median blood loss was minimal for LCWL and 28 ml for LCGB. No severe morbidity occurred in either procedure. Nine patients who underwent LCWL and 7 who underwent LCGB were postoperatively diagnosed with GBC. One of these patients had undergone LCGB for pathologically diagnosed T2 GBC after LCWL. All of the final surgical margins were negative. Three of these 15 patients underwent additional open surgery. The mean follow-up period was 26 mo, and only one patient developed recurrence. CONCLUSION: LCWL and LCGB are safe and useful procedures that allow complete resection of highly suspected or early-stage cancer and achieve good short-term and long-term results.

INTRODUCTION: Laparoscopic liver resection (LLR) has been widely performed throughout the world. Although prospective registry studies to clarify the safety of LLR have been feasible, no prior multicenter prospective study has addressed this issue. We have conducted a multicenter prospective cohort study to reveal the current status of LLR in Japan. METHODS: From April 2015 to March 2016, candidates for LLR were preoperatively enrolled at 12 institutions. The primary end-point was surgical safety, which was evaluated based on surgical factors and on short-term and midterm outcomes. RESULTS: A total of 102 patients were enrolled. Planned laparoscopic procedures included 96 pure laparoscopies, 1 hand-assisted laparoscopy, and 5 hybrid techniques. Non-anatomical partial resection or left lateral sectionectomy were performed in almost all cases. The median duration of surgery was 221 min. The median blood loss was 80.5 mL. Conversion was required for four patients (3.9%). The 90-day postoperative morbidities with grades more severe than II in the Clavien-Dindo classification were observed in six patients (5.9%). The median postoperative hospital stay was 9.5 days. No cases involved reoperation or mortality. CONCLUSION: Minor resection of LLR has been performed safely. To ensure the safe dissemination of LLR, including for major resection, a larger multicenter prospective study is required.
