ABSTRACT
OBJECTIVES: Both pancreatic stenting and rectal nonsteroidal anti-inflammatory drugs (NSAIDs) prevent post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. The aim of the study was to compare post-ERCP pancreatitis (PEP) prophylaxis using pancreatic stents and/or rectal NSAIDs prospectively. METHODS: A total of 321 patients undergoing ERCP were studied. Each patient was randomly allocated to receive pancreatic stent placement (PS), 50 mg of rectal diclofenac (NSAID), or both (PS + NSAID) for PEP prophylaxis. The primary outcome was the occurrence rate of PEP, and secondary outcomes included the severity of PEP and serum pancreatic amylase and lipase levels on the day after ERCP. RESULTS: Five patients (PS: 2/101, NSAID: 1/106, PS + NSAID: 2/102) developed PEP, and the overall occurrence rate of PEP was 1.6% (5/309). The occurrence rates of PEP in the PS, NSAID, and PS + NSAID groups were statistically equivalent with an equivalent margin of 10%. The severity of PEP was mild in all 5 patients. Median serum pancreatic amylase and lipase levels in the NSAID group were significantly lower than those in the PS and PS + NSAID groups. CONCLUSIONS: Rectal administration of 50 mg of diclofenac may become a first-line therapy for PEP prophylaxis in our country.

BACKGROUND/AIMS: The aim of this study was to elucidate clinical indicators for the detection of advanced colorectal cancer (ACRC). METHODS: This was a retrospective study conducted at a tertiary hospital. This study included 333 patients older than 85 years who underwent colonoscopy from April 2006 to May 2010. The detection rate of ACRC was assessed. Then, we analyzed the association between the detection of ACRC and various background factors including mean corpuscular volume (MCV). We also analyzed the cumulative overall survival of patients with detected ACRC. RESULTS: ACRC was found in 37 patients, resulting in a detection rate of 15%. Multivariate logistic regression analysis revealed that a decreased MCV was an independent predictor for the detection of ACRC (OR 0.88, 95% CI 0.84-0.94), whereas symptoms such as abdominal pain, hematochezia, or anemia were not independent predictors. MCV was an independent predictor irrespective of the location of the tumor. The cumulative survival rates at 3 and 5 years after diagnosis were 78 and 58%, respectively, during a median observational period of 30.3 months. CONCLUSION: This study demonstrated the usefulness of MCV as an indicator of the necessity of colonoscopy for older patients.

We report an adult who underwent laparoscopic orchidopexy and transabdominal preperitoneal hernia repair. The patient was a 53-year-old man who was referred to our hospital for a bulge and pain in his left inguinal area. An abdominal CT scan revealed that the greater omentum was incarcerated in a left inguinal hernia. The patient underwent emergency laparoscopic surgery immediately. After reduction, he was diagnosed with bilateral cryptorchidism and inguinal hernia. After adequate mobilization, pneumoperitoneum was discontinued, and orchidopexy was performed with the Lichtenstein tension-free hernioplasty. One month later, the patient underwent elective laparoscopic orchidopexy with transabdominal preperitoneal hernia repair on his right side. The patient's postoperative course has been uneventful, with no evidence of hernia recurrence to date. This procedure is safe and may be an option for adult patients who desire testis preservation. This may be the first report of laparoscopic hernia repair with orchidopexy.

We report a case of gastric volvulus with a large Bochdalek hernia successfully treated with emergency endoscopic reduction followed by elective laparoscopic mesh repair. The patient was a 71-year-old woman with no history of trauma. She was referred to our hospital because of nausea and vomiting after eating. Thoracic and abdominal CT showed gastric volvulus and a large Bochdalek hernia. The patient underwent emergency endoscopic reduction and elective laparoscopic surgery. The defect (10 × 12 cm) was reinforced with a Dual Mesh (expanded polytetrafluoroethylene) and fixed to the diaphragm with nonabsorbable sutures. The postoperative course was uneventful, and no complications or recurrence was found at the 2-year follow-up. The endoscopic reduction and elective laparoscopic procedure was performed successfully and resulted in significant clinical improvement in this case.

PURPOSE: Biochemical modulation of 5-fluorouracil (5-FU) by leucovorin (LV) enhances antitumor activity. LV is thus often added to 5-FU-based regimens for the treatment of metastatic colorectal cancer (mCRC). A combination of S-1, oxaliplatin, and LV (SOL) was shown to be feasible, effective, and safe in a previous phase I trial. We therefore conducted a randomized phase II trial to evaluate efficacy and safety of SOL compared with mFOLFOX6. METHODS: Patients with mCRC and no prior chemotherapy were randomly assigned to receive either SOL or mFOLFOX6. SOL consisted of S-1 (40-60 mg bid) plus oral LV (25 mg bid) for 1 week and oxaliplatin (85 mg/m(2)) on day 1, repeated every 2 weeks. RESULTS: Among 107 patients enrolled from July 2008 through July 2009, 105 (56 in the SOL group and 49 in the mFOLFOX6 group) were eligible and evaluated. The median progression-free survival was 9.6 months in the SOL group and 6.9 months in the mFOLFOX6 group [hazard ratio (HR) 0.83, 95 % confidence interval (CI) 0.49-1.40]. The median overall survival was 29.9 and 25.9 months, respectively (HR 0.91, 95 % CI 0.55-1.49). The response rate was 55 % in both groups. Grade 3 or 4 adverse drug reactions were neutropenia (20 % with SOL vs 41 % with mFOLFOX6), sensory neuropathy (20 vs 2.0 %), anorexia (13 vs 7.8 %), fatigue (11 vs 5.9 %), and diarrhea (11 vs 3.9 %). CONCLUSIONS: SOL demonstrated promising efficacy and acceptable toxicity as first-line chemotherapy for mCRC. Further studies of SOL combined with molecular target agents are warranted.

OBJECTIVE: The aim of this study was to evaluate the feasibility and conferred protection against recurrence of preoperatively administered tegafur suppositories following the intravenous and oral administration of fluoropyrimidine in a multicenter randomized control trial. METHODS: Patients with clinical T3/4 colorectal cancer were randomly assigned to receive the preoperative administration of tegafur suppositories (group A) or no preoperative treatment (group B). The primary end points were disease-free survival (DFS) and overall survival (OS). RESULTS: The mean follow-up periods were 80.9 ± 31.0 months in group A and 64.5 ± 28.8 months in group B. The 5-year DFS rates were 89.3% in group A and 70.3% in group B (p = 0.045), whereas the 5-year OS rates were 91.4% in group A and 73.2% in group B (p = 0.051). Furthermore, a significant difference in the cumulative distant metastatic rate was observed (group A, 7.4% vs. group B, 23.4%; p = 0.03). However, no significant difference in the cumulative local recurrence rate was seen (group A, 4.6% vs. group B, 8.2%; p = 0.68). CONCLUSION: Despite a relatively small sample size, preoperative tegafur suppositories might protect recurrences and improve survival rates, mainly by preventing distant metastasis. These findings suggest the utility of tegafur suppositories as an alternative neoadjuvant treatment in modern chemotherapy for colorectal cancer.

PURPOSE: We reevaluated the serum p53 antibody (S-p53Ab) ELISA kit, which was approved as a tumor marker of colon cancer in the Japanese Health Insurance System in 2007. METHODS: S-p53Ab was measured as a tumor marker in 154 colorectal cancer patients, and the results were categorized by clinical and pathological variables. We then compared the positive frequency of S-p53Ab, carcinoembryonic antigen (CEA), and carbohydrate 19-9 (CA19-9). RESULTS: S-p53Ab was positive in 33.1% of the colorectal cancer patients. The positive rate was significantly higher in patients with lymph nodes metastasis (P = 0.025) and lymphatic invasion (P = 0.023). In patients with stage I colorectal cancer, the positive rate of S-p53Ab (23.7%) was significantly higher than that of CEA (5.3%) or CA19-9 (7.9%). CONCLUSION: The approved kit for S-p53Ab testing was found to be an effective tumor marker of colorectal cancer. The positive rate of S-p53Ab was significantly higher in patients with cancer involvement of the lymphoid tissues. The positive rate of S-p53Ab was higher than that of CEA and CA19-9 in patients with stage I colorectal cancer, suggesting that the S-p53Ab is a useful tumor marker for patients with early-stage disease.

Adult intussusception is rare and most often associated with cancer. We report a case of intussuscepted sigmoid colon into the rectum protruding from the anus of a 47-year-old woman. The cause of the intussusception was sigmoid colon cancer. We removed the intussuscepted part of the sigmoid colon as well as the rectum and regional lymph nodes. The patient recovered uneventfully and there has been no evidence of recurrence of the cancer.
