ABSTRACT
INTRODUCTION: This study aimed to evaluate the impact of achieving < 37.7% excess body-weight loss (EBWL) within 3 months of postlaparoscopic sleeve gastrectomy (LSG) on clinical outcomes and its correlation with adipocyte function. METHODS: Patients (n = 176) who underwent LSG between January 2019 and January 2023 were included. Weight loss and status of health markers were monitored postoperatively. The cohort was stratified based on EBWL < 37.7% at 3 months or not. Variables including neutrophil-to-lymphocyte ratio (NLR), insulin resistance, and comorbidities were analyzed. Omental visceral and subcutaneous adipose tissue samples were used to analyze the differences in adipocyte function by western blot. RESULTS: Patients with EBWL < 37.7% at 3 months post-LSG (suboptimal group) comprised less likelihood of achieving ≥ 50% EBWL than those who achieved ≥ 37.7% EBWL (optimal group) at 6 months (42.55% vs. 95.52% in optimal group, p < 0.001), 12 months (85.11% vs. 99.25% in optimal group, p < 0.001) and 24 months (77.14% vs. 94.74% in optimal group, p = 0.009) post-LSG. High BMI (OR = 1.222, 95% CI 1.138-1.312, p < 0.001), NLR ≥ 2.36 (OR = 2.915, 95% CI 1.257-6.670, p = 0.013), and female sex (OR = 3.243, 95% CI 1.306-8.051, p = 0.011) significantly predicted EBWL < 37.7% at 3 months post-LSG. Patients with NLR ≥ 2.36 had significantly lower adipose triglyceride lipase in omental fat (p = 0.025). CONCLUSION: EBWL < 37.7% at 3 months post-LSG is a strong predictor of subsequent suboptimal weight loss. High BMI, NLR ≥ 2.36, and female sex are risk factors in predicting EBWL < 37.7% at 3 months post-LSG. These findings may offer a reference to apply adjuvant weight loss medications to patients who are predisposed to suboptimal outcomes.

INTRODUCTION: Defining recurrent weight gain after metabolic bariatric surgery poses a significant challenge. Our study aimed to standardize recurrent weight gain measurements in patients undergoing laparoscopic sleeve gastrectomy (LSG) and ascertain its association with comorbidity progression. METHODS: We conducted a retrospective data analysis on 122 patients who underwent LSG, tracking their progress over 2-7 years. Data on weight, blood pressure measurements, and laboratory tests were collected, focusing on the postoperative period to identify nadir weight, total weight loss, and recurrent weight gain. RESULTS: Significant weight loss and comorbidity remission were noted, with diabetes, hypertension, and dyslipidemia showing substantial remission rates of 85.71%, 68.24%, and 85.37%, respectively. The median recurrent weight gain was 6.30 kg within 12 months of the nadir. Progression proportion of diabetes, hypertension, and dyslipidemia were 8.20%, 44.26%, and 40.98%, respectively. Hypertension progression was strongly associated with a recurrent weight gain ≥ 10 kg and ≥ 20% of maximum weight loss. Dyslipidemia progression was significantly correlated with recurrent weight gain ≥ 10 kg and ≥ 20% of maximum weight loss. Diabetes progression was significantly correlated with recurrent weight gain ≥ 10% of pre-surgery body weight and ≥ 25% of maximum weight loss. A ≥ 10% weight gain of maximum weight loss did not significantly impact the progression of these conditions. CONCLUSION: Recurrent weight gain ≥ 20% of maximum weight loss can be treated as a specific threshold indicating comorbidity progression post-LSG. Standardizing the measurement of recurrent weight gain can help healthcare providers to implement targeted management strategies to optimize long-term health outcomes.

BACKGROUND: Despite a significant 30% ten-year readmission rate for SBO patients, investigations into recurrent risk factors after non-operative management are scarce. The study aims to generate a risk factor scoring system, the 'Small Bowel Obstruction Recurrence Score' (SBORS), predicting 6-month recurrence of small bowel obstruction (SBO) after successful non-surgical management in patients who have history of intra-abdominal surgery. METHODS: We analyzed data from patients aged ≥ 18 with a history of intra-abdominal surgery and diagnosed with SBO (ICD-9 code: 560, 568) and were successful treated non-surgically between 2004 and 2008. Participants were divided into model-derivation (80%) and validation (20%) group. RESULTS: We analyzed 23,901 patients and developed the SBORS based on factors including the length of hospital stay > 4 days, previous operations > once, hemiplegia, extra-abdominal and intra-abdominal malignancy, esophagogastric surgery and intestino-colonic surgery. Scores > 2 indicated higher rates and risks of recurrence within 6 months (12.96% vs. 7.27%, OR 1.898, p < 0.001 in model-derivation group, 12.60% vs. 7.05%, OR 1.901, p < 0.001 in validation group) with a significantly increased risk of mortality and operative events for recurrent episodes. The SBORS model demonstrated good calibration and acceptable discrimination, with an area under curve values of 0.607 and 0.599 for the score generation and validation group, respectively. CONCLUSIONS: We established the effective 'SBORS' to predict 6-month SBO recurrence risk in patients who have history of intra-abdominal surgery and have been successfully managed non-surgically for the initial obstruction event. Those with scores > 2 face higher recurrence rates and operative risks after successful non-surgical management.

BACKGROUND: A long-acting κreceptor agonist parenteral analgesic may theoretically improve acute pain and reduce incidence of chronic postsurgical pain (CPSP) after laparoscopic cholecystectomy with minimal drug-related side effects of the traditional µreceptor opioids. METHODS: Eighty adult patients undergoing elective laparoscopic cholecystectomy were randomly assigned to receive single intramuscular injection of an extended-release sebacoyl dinalbuphine ester (SDE, Naldebain 150 mg; n = 40) or placebo (n = 40) after anesthesia induction. Standard multimodal analgesia (MMA) was administered for postoperative pain control. The primary endpoint was pain intensity within 7 days after surgery. The secondary endpoints were incidence CPSP at 3 months and adverse reactions up to 7 days after surgery. RESULTS: The highest visual analogue scale (VAS) and area under the curve of VAS 0 to 48 hours after operation were not different between the two groups and a similar proportion of patients requested rescue parenteral analgesics. Average pain intensities were also not different at 72 hours and 7 days after surgery. Incidence of CPSP was 22.5% and 13.1% in patients who received placebo and SDE treatment, respectively (P = .379). Significantly higher incidence of drug-related adverse events, including dizziness, nausea and injection site reactions, were recorded in the SDE group. CONCLUSION: A single dose of extended-release analgesic SDE given intraoperatively did not provide sufficient add-on effect for acute and chronic pain management after laparoscopic cholecystectomies in patients who received standard postoperative MMA. Intramuscular injection of 150 mg SDE in patients with average body mass causes adverse events that could have been overlooked. More clinical studies are warranted to determine the target populations who may benefit from SDE injections for improvement of acute and chronic postsurgical pain management.

BACKGROUND: The major treatment for perforated peptic ulcers (PPU) is surgery. It remains unclear which patient may not get benefit from surgery due to comorbidity. This study aimed to generate a scoring system by predicting mortality for patients with PPU who received non-operative management (NOM) and surgical treatment. METHOD: We extracted the admission data of adult (≥ 18 years) patients with PPU disease from the NHIRD database. We randomly divided patients into 80% model derivation and 20% validation cohorts. Multivariate analysis with a logistic regression model was applied to generate the scoring system, PPUMS. We then apply the scoring system to the validation group. RESULT: The PPUMS score ranged from 0 to 8 points, composite with age (< 45: 0 points, 45-65: 1 point, 65-80: 2 points, > 80: 3 points), and five comorbidities (congestive heart failure, severe liver disease, renal disease, history of malignancy, and obesity: 1 point each). The areas under ROC curve were 0.785 and 0.787 in the derivation and validation groups. The in-hospital mortality rates in the derivation group were 0.6% (0 points), 3.4% (1 point), 9.0% (2 points), 19.0% (3 points), 30.2% (4 points), and 45.9% when PPUMS > 4 point. Patients with PPUMS > 4 had a similar in-hospital mortality risk between the surgery group [laparotomy: odds ratio (OR) = 0.729, p = 0.320, laparoscopy: OR = 0.772, p = 0.697] and the non-surgery group. We identified similar results in the validation group. CONCLUSION: PPUMS scoring system effectively predicts in-hospital mortality for perforated peptic ulcer patients. It factors in age and specific comorbidities is highly predictive and well-calibrated with a reliable AUC of 0.785-0.787. Surgery, no matter laparotomy or laparoscope, significantly reduced mortality for scores < = 4. However, patients with a score > 4 did not show this difference, calling for tailored approaches to treatment based on risk assessment. Further prospective validation is suggested.

BACKGROUND/AIM: Colorectal cancer (CRC) is one of the most common malignancies and cause of cancer-related deaths worldwide. The combination of chemotherapeutics working with different mechanisms enhances the therapeutic effects and delays the development of resistance. This study investigated the anticancer effect of the combination of ribociclib (LEE011) and irinotecan (SN38) on CRC cells. MATERIALS AND METHODS: HT-29 and SW480 cells were treated with LEE011, SN38, or the combination of LEE011 and SN38. Cell viability and cell cycle distribution were analyzed. The expression of cell cycle- and apoptosis-related proteins was determined using western blot. RESULTS: The combination of LEE011 and SN38 elicited a synergistic antiproliferative effect on HT-29 (PIK3CAP449T mutation) cells, and an antagonistic antiproliferative effect on SW480 (KRASG12V mutation) cells. LEE011 inhibited retinoblastoma protein (Rb) phosphorylation and led to G1 arrest in HT-29 and SW480 cells. SN38 treatment caused a significant increase in the phosphorylation levels of Rb, cyclin B1, and CDC2 in SW480 cells and induced S phase arrest. Furthermore, SN38 treatment increased the phosphorylation levels of p53 and activated caspase-3 and caspase-8 in HT-29 and SW480 cells. LEE011-induced G1 arrest contributed to its synergistic antiproliferative effect with SN38 in HT-29 cells through the down-regulation of the phosphorylation of Rb. In addition, it elicited an antagonistic effect with SN38 in SW480 cells by changing the phosphorylation levels of Rb and activating caspase-8. CONCLUSION: The effects of the combination of LEE011 and conventional chemotherapy drugs on CRC depend on the chemotherapy drug and the specific gene mutation harbored by tumor cells.

A continuous increase in follicular lymphoma has been observed in Taiwan, Japan, and South Korea over the last few decades. This study aimed to evaluate the difference in incidence trends of follicular lymphoma in Taiwan, Japan, and South Korea between 2001 and 2019. The data for the Taiwanese populations was obtained from the Taiwan Cancer Registry Database, and those for the Japanese and Korean population were retrieved from the Japan National Cancer Registry and some additional reports, both of which included population-based cancer registry data, from Japan and Korea. Follicular lymphoma accounted for 4231 cases from 2002-2019 in Taiwan, 3744 cases from 2001-2008 and 49,731 cases from 2014-2019 in Japan; and 1365 cases from 2001-2012 and 1244 cases from 2011-2016 in South Korea. The annual percentage change for each time period was 3.49% (95% confidence interval: 2.75-4.24%) in Taiwan, 12.66% (95% confidence interval [CI]: 9.59-15.81%) and 4.95% (95% CI: 2.14-7.84%) in Japan, and 5.72% (95% CI: 2.79-8.73%) and 7.93% (95% CI: -1.63-18.42%) in South Korea. Our study confirms that the increasing trends of follicular lymphoma incidence in Taiwan and Japan have been remarkable in recent years, especially the rapid increase in Japan between 2014 and 2019; however, there was no significant in-crease from 2011 to 2015 in South Korea.
ABSTRACT
PURPOSE: µ-receptor opioids are associated with unwanted gastrointestinal side effects and respiratory depression. A long-acting non-µ-receptor parenteral opioid is not currently available for management of acute and chronic postsurgical pain (CPSP). This double-blind clinical trial tested an extended-release κ-receptor agonist, sebacoyl dinalbuphine ester (SDE, Naldebain®) for management of surgical pain after laparoscopic bariatric surgery. MATERIALS AND METHODS: Patients were randomly assigned to receive a single intramuscular injection of SDE (150 mg, n = 30) or vehicle solution (n = 30) at > 12 h before surgery. All patients received standard perioperative multimodal analgesia (MMA). The primary endpoint was the pain intensity in the beginning 7 days after operation. The secondary endpoints were adverse reactions up to 7 days and incidence of CPSP at 3 months after surgery. RESULTS: Compared with placebos, the area under curves of visual analog scale (VAS) for 0-48 h after operation were significantly reduced in SDE group (143.3 ± 65.4 and 105.9 ± 36.3, P = 0.025). There were significantly fewer patients in the SDE group who had moderate-to-severe pain (VAS ≥ 4) (16.7% vs 50%; P = 0.012) at postoperative 48 h. Pain intensities were similar between the two groups at 72 h and 7 days postoperatively. The incidence of CPSP at 3 months was not different. SDE did not increase drug-related systemic adverse events. CONCLUSION: In addition to the standard perioperative MMA, a single-dose injection of long-acting κ-receptor agonist SDE provides significantly better pain management for 48 h following laparoscopic bariatric surgery. A long-acting κ-receptor agonist opioid could improve in-hospital pain management and potentiate early discharge after operation without increasing drug-related systemic complications.

Surgery for acute mesenteric infarction (AMI) is associated with high mortality. This study aimed to generate a mortality prediction model to predict the 30-day mortality of surgery for AMI. We included patients ≥18 years who received bowel resection in treating AMI and randomly divided into the derivation and validation groups. After multivariable analysis, the 'Surgery for acute mesenteric infarction mortality score' (SAMIMS) system was generated and was including age >62-year-old (3 points), hemodialysis (2 points), congestive heart failure (1 point), peptic ulcer disease (1 point), diabetes (1 point), cerebrovascular disease (1 point), and severe liver disease (4 points). The 30-day-mortality rates in the derivation group were 4.4%, 13.4%, 24.5%, and 32.5% among very low (0 point), low (1−3 point(s)), intermediate (4−6 points), and high (7−13 points)-risk patients. Compared to the very-low-risk group, the low-risk (OR = 3.332), intermediate-risk (OR = 7.004), and high-risk groups (OR = 10.410, p < 0.001) exhibited higher odds of 30-day mortality. We identified similar results in the validation group. The areas under the ROC curve were 0.677 and 0.696 in the derivation and validation groups. Our prediction model, SAMIMS, allowed for the stratification of the patients' 30-day-mortality risk of surgery for acute mesenteric infarction.
ABSTRACT
PURPOSE: Weight reduction decreases gastroesophageal reflux disease (GERD), but laparoscopic sleeve gastrectomy (LSG) that damages the structure of the stomach may worsen GERD. We aimed to elucidate the factors associated with increased severity of erosive esophagitis (EE) at 1 year after LSG. MATERIALS AND METHODS: Data on patients who underwent LSG between February 2007 and March 2016 were reviewed. Endoscopic findings and anthropometric data before and after surgery were recorded. The severity of EE was assessed according to the Los Angeles classification; severe EE was defined as grade C or D esophagitis. RESULTS: Totally, 316 patients were enrolled. Before LSG, 96 patients (30.4%) had grade A or B EE. One year after LSG, 215 patients (68%) had EE, including 136 (43%) with grade A, 62 (19.6%) with grade B, and 17 (5.4%) with grade C or D EE. One-hundred and twenty-seven of 220 patients (57.7%) without EE before LSG developed de novo EE following LSG. The incidence of severe EE after LSG in patients without pre-operative EE, grade A EE, or grade B EE at baseline was 3.2%, 6.8%, and 50%, respectively. Independent factors for an increased severity of EE after LSG were male gender (OR = 2.55, 95% CI = 1.52-4.28) and post-operative hiatal hernia (OR = 3.17, 95% CI = 1.66-6.06). CONCLUSION: The prevalence and severity of EE increased after LSG. Male gender and post-operative hiatal hernia are independent factors for an increased severity of EE after LSG. The incidence of severe EE after LSG is low for patients without pre-operative EE or grade A EE at baseline.

Purpose: This study aims to identify the pre- and postoperative changes in the neutrophil-lymphocyte ratio (NLR) and its correlations to clinical characteristics in obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Method: Retrospectively, we included patients who has undergone LSG in our institution between January 2019 and April 2021. A total of 100 patients whose body mass index over 32.5 and received primary laparoscopic sleeve gastrectomy without infectious condition were included. Results: There was a significant decline in NLR (T0 vs. POM3 2.21 vs. 1.78, p = 0.005), neutrophil (T0 vs. POM3 5369 vs. 4050, p < 0.001) and lymphocyte count (T0 vs. POM3 2440: 2100, p < 0.001, respectively) at postoperative 3 months (POM3) compared to preoperative (T0) levels, but similar between POM3 and POM6. The declined counts (Neutrophile vs. Lymphocyte 1445.5/µl vs. 323.5/µl, p < 0.001) and percentage (Neutrophile vs. Lymphocyte 25.11% vs. 13.07%, p < 0.001) of neutrophile are higher than lymphocyte from T0 to POM3, but similar in POM3 and POM6. Preoperative NLR has a significant correlation with the preoperative body weight, preoperative insulin level, and excessive body weight loss (EBWL) at POM3. Preoperative NLR <2.36 had a sensitivity of 67.6% and a specificity of 62.5% in predicting successful weight loss (EBWL > 37.7%) at POM3 (AUC = 0.635, p = 0.032). Conclusion: There was a significant decline in NLR, neutrophil, and lymphocyte count from T0 to POM3, but similar between POM3 and POM6. The declined counts and percentage of neutrophile are higher than lymphocyte. Preoperative NLR shows the potential to be used as a prognostic biomarker for predicting successful weight loss at POM3 after LSG. Further studies could be designed to evaluate the value of prediction in successful outcome after LSG and figure out the relationship between the changes of neutrophil function and oncogenesis.
ABSTRACT
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a commonly performed bariatric surgery. Gastric stenosis and leaks are 2 major complications associated with LSG and revision surgery might be needed. Herein, we report our experience of intraoperative endoscopy (IOE) to evaluate stenosis and leaks during LSG. METHODS: LSG was performed by three surgeons. Patients who underwent LSG and IOE between January 2016 and March 2020 were enrolled and assigned to two groups: group 1 (1st-30th LSG case for each surgeon) and group 2 (> 30th LSG for each surgeon). Patients' anthropometric and biochemical data pre- and post-LSG, as well as IOE findings and follow-up esophagogastroduodenoscopy records were reviewed. RESULTS: In total, 352 patients were enrolled including 90 patients in group 1 and 262 patients in group 2. Three out of 352 patients (0.9%) were found to have stenosis by IOE, which was related to tightly gastropexy stitch or reinforcement stitch, all of which were in group 1. Stenosis was resolved after removal of the stitch during LSG. The incidence of gastric stenosis detected by IOE was 3.3% (3/90) and 0% (0/262) in group 1 and group 2, respectively (P = 0.003). No leakage was found in this study and no patient developed clinical or endoscopic stenosis after LSG. CONCLUSIONS: The existing evidence showed that IOE can help detect gastric stenosis during LSG, especially for novice surgeons, and the stenosis could be resolved during operation.

Some studies showed that when distant metastasis or locally advanced tumors were observed, the participation of 2 or more operating surgeons (combined surgery) in the operation could improve the prognosis of patients. The multispecialty operative team would perform combined surgery in colon cancer patients with some complications since 2015. The goal of this study is to confirm performing combined surgery would improve the outcomes of colon cancer patients. A retrospective observational study was conducted, which involved all colon cancer patients between November 2015 and December 2019 at one would-be medical center. Patients were divided into 3 cohorts: those with complicated cases and had combined surgery (C_2S), those with complicated cases and had surgery performed by a single surgeon (C_1S), and those with uncomplicated cases and had surgery performed by a single surgeon (NC_1S). Overall survival and disease-free survival were compared among the 3 groups. A total of 296 colon cancer patients during the study period. Among them, 35 were C_2S, 87 were C_1S, and 174 were NC_1S. Patients in the NC_1S group had significantly higher 12-, 24-, and 36-month OS rates compared to those in the C_1S group (P < .01). In contrast, there was no significant difference in overall survival among patients in the NC_1S and C_2S group (P =.15). The quality of surgery must be impact the prognosis, especially in the individual who was complicated case, the survival in patients who had surgery performed by multispecialty operative team would be improved.

BACKGROUND: Liver metastases from breast cancer are associated with poor prognosis, and treatment options are usually restricted to palliative systemic therapy. The impact of liver resection on metastasis remains controversial. The aim of this study is to investigate whether liver resection can offer better survival outcomes in cases of isolated liver metastases from breast cancer. METHODS: We conducted a nationwide cohort study using a claims dataset from Taiwan's National Health Insurance Research Database (NHIRD). We identified all patients with breast cancer (diagnostic code ICD-9: 174.x) from the Registry for Catastrophic Illness Patient Database (RCIPD) of the NHIRD who underwent mastectomy between January 1, 2000, and December 31, 2008. Patients with other malignancies (history, initially, or during follow-up), those with a history of metastasis prior to or at initial admission for mastectomy, and those without liver metastases were excluded. Patients with other metastases between mastectomy and liver metastasis and those who died at first admission for liver resection were also excluded. All patients were followed up until December 31, 2013, or withdraw from the database because of death. RESULTS: Data were analyzed for 1,116 patients who fulfilled the inclusion criteria (resection group: 89; non-resection group: 1,027). There were no differences in age, Charlson Comorbidity Index, or major coexisting diseases except renal disease between two groups. Kaplan-Meier analysis demonstrated that the liver resection group had significantly better overall survival (OS) than the non-resection group. (1-year: 96.6% vs. 52.3%, 2-year: 86.8% vs. 35.4%, 3-year: 72.3% vs. 25.2%, 5-year: 51.6% vs. 16.9%, respectively, p<0.001). Cox analysis revealed that the liver resection group exhibited a significant improvement in patient survival (hazard ratio [HR] = 0.321, 95% confidence interval [CI]: 0.234-0.440, p<0.001). CONCLUSION: These findings indicate that liver resection may offer better survival benefit in patients with breast cancer who develop new liver metastases post mastectomy.

Herein, we aimed to explore whether male patients with congenital collagen diseases had a higher risk of inguinal herniation than patients without these diseases. Data were retrospectively collected from the National Health Insurance Research Database of Taiwan. The study cohort included 1,801 male patients diagnosed with congenital collagen diseases based on the ICD-9 CM diagnostic codes; after propensity score matching, the control group comprised 6,493 men without congenital collagen diseases. The primary endpoint was inguinal hernia repair during the observation period. During a median follow-up period of 133.9 months, the risk of inguinal herniation in the collagen group was significantly higher than that in the control group (HR = 2.237, 95% CI 1.646-3.291, p < 0.001). This phenomenon was observed in patients younger than 18 years (HR: 3.040, 95% CI 1.819-5.083, p < 0.001) and in those aged 18-80 years (HR: 1.909, 95% CI 1.186-3.073, p < 0.001). Asian men with congenital collagen diseases are at a high risk of developing inguinal hernias, regardless of age. Detailed physical examination and patient education should be performed for these patients to prevent inguinal herniation.

PURPOSE: We aimed to evaluate the efficacy of the predictive tool, 6M50LSG scoring system, to identify suspected poor responders after laparoscopic sleeve gastrectomy (LSG). METHODS: The 6M50LSG scoring system has been applied since 2019. Suspected poor responders are defined by EBWL at 1 month < 19.5% or EBWL at 3 months < 37.7% based on the 6M50LSG scoring system. Our analysis included 109 suspected poor responders. Based on the date of LSG, the patients were separated into two groups: the 2016-2018 group (before group, BG, with regular care) and the 2019-2020 group (after group, AG, with upgrade medical nutrition therapy). RESULTS: At the end of the study, the AG group had a significantly higher proportion of adequate weight loss, which was defined as EBWL ≥ 50% at 6 months after LSG, than that in the BG group (18.92% in BG vs. 48.57% in AG, p = 0.003). The AG group demonstrated significantly more 3-months-TWL (BG: 15.22% vs. AG: 17.54%, p < 0.001) and 6-months-TWL (BG: 21.08% vs. AG: 25.65%, p < 0.001). In multivariate analyses and adjustments, the scoring system (AG) resulted in significantly higher chances of adequate weight loss in suspected poor responders (adjusted OR 3.392, 95% CI = 1.345-8.5564, p = 0.010). One year after LSG, suspected poor responders in AG had a significantly higher weight loss than those in BG (BG vs. AG: TWL 27.17% vs. 32.20%, p = 0.014) . CONCLUSION: This study confirmed that the 6M50LSG scoring system with upgraded medical nutrition therapy increased the proportion of suspected poor responders with adequate weight loss after LSG.

INTRODUCTION: Our study aims to identify that patients who received hernia repair previously did have higher risk of occurrence of newly developed inguinal hernia, named as a contralateral inguinal hernia (CIH), than patients who never received inguinal hernia surgery before. MATERIALS AND METHODS: We collected data from the National Health Insurance Research Database (NHIRD) of Taiwan retrospectively. In the study cohort, 64,089 Asian male adults who underwent primary unilateral inguinal hernia repair during 2003-2008 were included using ICD-9 diagnostic and surgical codes. Another 64,089 male adults without hernia repair history were included as control group via propensity score match. RESULTS: The median follow-up period is 93.53 months. After multivariate analysis, the risk of newly developed inguinal hernia in unilateral inguinal hernia (UIH) repair cohort was significantly higher (adjusted HR 6.364, 95% CI 6.012-6.737, P < 0.001) than the control group. In subgroup analysis, patients without mesh repair (adjusted HR 6.706, P < 0.001) and patients with mesh repair (adjusted HR 5.559, P < 0.001) both showed higher risk of developing newly developed inguinal hernia which needs repair. CONCLUSIONS: Asian men with UIH repair history had a higher risk of developing new inguinal hernia at the contralateral site, namely CIH, than the general population. The surgeon should inform the possibility of CIH after initial herniorrhaphy, therefore, monitoring the occurrence of CIH is necessary.

BACKGROUND: Organophosphate poisoning is a serious issue and it results in significant casualties in developing countries. Since agriculture remains an important and necessary sector of human society and organophosphate are commonly used in agriculture, it is difficult to prevent organophosphate poisoning. Gastrointestinal bleeding is not a common but life threatening symptom of organophosphate poisoning. We report a rare case of gastrointestine bleeding due to organophosphate poisoning. CASE PRESENTATION: A 78-year-old woman presented to our hospital approximately 12 h after ingesting a mouthful of organophosphate and benzodiazepines in a suicide attempt. Six weeks after successful medical treatment for respiratory failure, she developed recurring melena. Colonoscopy and esophagogastroduodenoscopy findings were negative for ulcers or bleeding. Enteroscopy revealed severe circumferential ulcers with luminal narrowing 10 cm proximal to the ileocecal valve. The patient underwent a 100-cm ileum resection after failed medical treatment and recovered uneventfully. The resected terminal ileum demonstrated severe inflammation and a sharp transitional zone between the healthy and injured mucosa approximately 50 cm proximal to the ileocecal valve. Pathological examination revealed an injured mucosa with inflammatory cell infiltration and structural damage. This case highlights a rare event of OP poisoning with late-onset lower gastrointestinal bleeding, which prolonged the patient's recovery course and parenteral alimentation period. CONCLUSION: We report a rare case of a patient with organophosphate poisoning, with late-onset lower GI tract bleeding, which raised clinical awareness regarding the organophosphate poisoning that induce intestinal symptoms.

Background: Post-stroke dementia may affect up to one-third of stroke survivors. Acupuncture as a complementary treatment for stroke has been shown to be beneficial for subsequent post-stroke rehabilitation. The purpose of this retrospective cohort study was to investigate the potential effect of acupuncture to protect stroke patients from dementia. Methods: We included 9,547 patients receiving ambulatory or hospital care for stroke and 9.547 non-stroke patients; patients were matched for sex, age, and Charlson Comorbidity Index. Each individual was traced for the subsequent development of dementia. Two thousand four hundred and forty-nine stroke patients received acupuncture treatment and 7,098 residue stroke patients without acupuncture treatment served as control groups. This is a 3-year follow-up cohorts study: the incidence and adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) of post- stroke dementia in the Cox proportional hazard regression. Results: During the 3-year follow-up, 1,403 patients with stroke (14.70%) and 427 patients without stroke (4.47%) developed dementia. The adjusted HRs of development of dementia among stroke patients were 3.64-times (range, 3.27-4.06), and the incidence of dementia was higher in male. Stroke patients receiving acupuncture treatment had a lower probability of dementia than those without acupuncture during the follow-up period, the adjusted HRs was 0.49 (95% CI, 0.42-0.58; p < 0.001). Conclusions: The association between stroke and dementia existed in both sexes, more prominent in male. Patients with stroke receiving acupuncture treatments showed decreased risk of dementia. Care must be taken evaluating these results because this study was limited to lack of information regarding lifestyles, stroke severities, and acupuncture methods that were used in treatments.
ABSTRACT
PURPOSE: This study assessed the benefits and efficacy of bariatric surgery (BS) in reducing the risk of cancer in Asians with morbid obesity. METHODS: Records for patients aged between 18 and 55 years whose diagnoses corresponded with the ICD-9 codes for obesity and BS were extracted from the National Health Insurance Research Database (NHIRD) in Taiwan between 2000 and 2015. The patients who underwent BS (BS group), those who did not undergo BS (NS group), and the general population (GP group) were propensity score matched. The outcome was newly diagnosed malignancy. Data were extracted from the Registry for Catastrophic Illness Patient Database (RCIPD) of the NHIRD. RESULTS: The BS group developed significantly less malignancy (1.18%) than the GP group (1.46%, p = 0.0364). There was no statistically significant difference in malignancy risk between the BS and GP groups (aHR =1.00, p = 0.9997). The NS group developed significantly higher malignancy (2.48%) than the GP group (1.97%, p < 0.0001). There was a significantly higher malignancy risk in the NS group (aHR =1.22, p < 0.0001) than in the GP group. In the subgroup analysis, the malignancy risks of the NS group were significantly higher in the subgroup of men aged between 18 and 35 years (aHR =1.37, p = 0.003) and women aged between 18 and 35 years (aHR = 1.62, p < 0.0001), and 35-55 years (aHR = 1.27, p < 0.0001). All the subgroup analyses between the BS and GP groups demonstrated no significant differences. CONCLUSIONS: Our study demonstrated that BS reduced the risk of malignancy in patients with morbid obesity, particularly in women and young men.
