Total abdominal colectomy versus diverting loop ileostomy with colonic lavage for fulminant clostridium difficile colitis: an updated systematic review and meta-analysis of outcomes.

PURPOSE: Diverting Loop Ileostomy (DLI) with intraoperative colonic lavage has emerged as a potential alternative to Total Abdominal Colectomy (TAC) for treating Fulminant Clostridium Difficile Colitis (FCDC). This study aims to provide an updated review comparing DLI with TAC in managing FCDC. METHODS: A systematic literature search was conducted using PubMed, Scopus, and Embase to identify retrospective and prospective studies comparing DLI with TAC for fulminant CDC treatment. A meta-analysis was performed to evaluate postoperative mortality rates and complications using R Studio version 4.4.1, calculating odds ratios (ORs) with 95% confidence intervals via the Mantel-Haenszel method. Heterogeneity was assessed using the Cochrane Q test and I2 statistics. RESULTS: Our search yielded 228 relevant citations, of which 7 studies with a total of 7,048 patients were included. Of these, 1,728 underwent DLI. The mean age was 63.33 years in the DLI group and 65.74 years in the TAC group. Compared to TAC, DLI had significantly lower postoperative mortality (OR 0.75; 95% CI 0.62-0.90; P = 0.002; I2 = 34%). Trial sequential analysis for postoperative mortality rates showed the benefit of DLI with a sufficiently powered sample. The DLI group also had a significantly higher rate of ostomy reversal (OR 5.68; 95% CI 2.35-13.72; P < 0.001; I2 = 36%). Postoperative complications, such as thromboembolic events, surgical site infections, urinary tract infections, renal failure, and pneumonia, were not significantly different. CONCLUSION: DLI shows a lower postoperative mortality rate and higher ostomy reversal rate than TAC, suggesting it as a potential organ-preserving, minimally invasive alternative. Further high-quality studies and trials are needed to confirm these findings.

Receptor-Interacting Serine/Threonine-Protein Kinase-2 as a Potential Prognostic Factor in Colorectal Cancer.

Background and objectives: Receptor-interacting serine/threonine-protein kinase-2 (RIPK2) is an important mediator in different pathways in the immune and inflammatory response system. RIPK2 was also shown to play different roles in different cancer types; however, in colorectal cancer (CRC), its role is not well established. This study aims at identifying the role of RIPK2 in CRC progression and survival. Materials and methods: Data of patients and mRNA protein expression level of genes associated with CRC (RIPK2, tumor necrosis factor (TNF), TRAF1, TRAF7, KLF6, interlukin-6 (Il6), interlukin-8 (Il8), vascular-endothelial growth factor A (VEGFA), MKI67, TP53, nuclear factor-kappa B (NFKB), NFKB2, BCL2, XIAP, and RELA) were downloaded from the PrognoScan online public database. Patients were divided between low and high RIPK2 expression and different CRC characteristics were studied between the two groups. Survival curves were evaluated using a Kaplan-Meier estimator. The Pearson correlation was used to study the correlation between RIPK2 and the other factors. Statistical analysis was carried out using SPSS version 25.0. The Human Protein Atlas was also used for the relationship between RIPK2 expression in CRC tissues and survival. Differences were considered statistically significant at p < 0.05. Results: A total of 520 patients were downloaded from the PrognoScan database, and RIPK2 was found to correlate with MKI67, TRAF1, KLF6, TNF, Il6, Il8, VEGFA, NFKB2, BCL2, and RELA. High expression of RIPK2 was associated with high expression of VEGFA (p < 0.01) and increased mortality (p < 0.01). Conclusions: In this study, RIPK2 is shown to be a potential prognostic factor in CRC; however, more studies are needed to assess and verify its potential role as a prognostic marker and in targeted therapy.

Safety and Efficacy of Barbed Sutures Compared to Non-barbed Sutures in Bariatric Surgery: An Updated Systematic Review and Meta-analysis.

PURPOSE: Mastering intracorporeal suturing is challenging in the evolution from conventional to laparoscopic bariatric surgery. Among various techniques competing for superiority in overcoming this hurdle, we focus on exploring the potential of barbed sutures through a meta-analysis that compares outcomes to those of conventional non-barbed sutures in bariatric surgery. MATERIALS AND METHODS: We conducted a comprehensive search on PubMed, Scopus, and Embase to identify studies comparing barbed sutures with non-barbed sutures in bariatric surgeries, focusing on outcomes such as operative time, suturing time, postoperative complications, and hospital stay. The statistical analysis was carried out using RStudio version 4.3.2. Heterogeneity was assessed using the Cochrane Q test and I2 statistics. RESULTS: Incorporating data from 11 studies involving a total of 27,442 patients, including 3,516 in the barbed suture group across various bariatric surgeries, our analysis demonstrates a significant reduction in suturing time (mean difference -4.87; 95% CI -8.43 to -1.30; p < 0.01; I2 = 99%) associated with the use of barbed sutures. Specifically, in Roux-en-Y gastric bypass, we observed a significant decrease in operative time (mean difference -12.11; 95% CI -19.27 to -4.95; p < 0.01; I2 = 93%). Subgroup analyses and leave-one-out analyses consistently supported these findings. Furthermore, we found that the mean body mass index did not significantly predict the mean difference in operative time outcome. No significant differences emerged in hospital stay or postoperative complications, including leak, bleeding, stenosis, and bowel obstruction (p > 0.05). CONCLUSION: Our study findings address barbed sutures as a potential alternative for laparoscopic intracorporeal suturing in bariatric surgery.

Anastomotic metabolic and bariatric surgeries with same-day discharge: 30-day outcomes of a cohort from a high-volume center in Canada.

BACKGROUND: On the basis of our extensive experience in same-day discharge (SDD) sleeve gastrectomy, we extended this management strategy to anastomotic metabolic and bariatric surgeries (MBS). OBJECTIVES: To retrospectively analyze early outcomes (≤30 d) after anastomotic MBS with planned SDD (≤12 hr). SETTING: University Hospital, Canada; Public Practice. METHODS: SDD anastomotic MBS were proposed with strict preoperative criteria and included single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S), Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), and single-anastomosis sleeve ileal bypass (SASI). Enhanced recovery after bariatric surgery protocols and post-anesthesia care unit criteria were followed. Unplanned overnight stay, emergency department (ED) visit, readmission, morbidity-mortality, and reintervention rates were analyzed. RESULTS: Since 2021, 208 patients (191 female and 17 male) have undergone SDD anastomotic MBS, with 76% conversion procedures: 92 SADI-S, 72 RYGB, 35 OAGB, and 9 SASI (mean age = 41.4 yr and mean preoperative body mass index = 41.9 kg/m2). Unplanned overnight stays and ED visits were 4.8% and 4.3%, respectively. Readmission rate was 5.8% (5 SADI-S, 5 RYGB, 1 OAGB, and 1 SASI). Overall morbidity rate was 14.9%, including 3.9% major complications. Within 30 days postoperatively, there were 2 duodenal leaks, 1 intrabdominal collection, 1 common bile duct stenosis, and 1 acute appendicitis in the SADI-S group. There were 2 occlusions on the jejunojejunal anastomosis and 1 bleeding on the gastrojejunal anastomosis in the RYGB group. Five (2.4%) required reintervention with no mortality. CONCLUSIONS: We report low and acceptable rates of unplanned overnight stay, readmission, and reintervention. Early outcomes suggest that SDD anastomotic MBS seems safe and feasible with an experienced team, selective criteria, and appropriate postoperative follow-up.

Outcomes of Single Anastomosis Sleeve Ileal (SASI) Bypass as an Alternative Procedure in Treating Obesity: An Updated Systematic Review and Meta-Analysis.

PURPOSE: The Single Anastomosis Sleeve Ileal (SASI) bypass is a novel bariatric procedure that simplifies Santoro's procedure, balancing functional restriction and neuroendocrine modulation while preserving anatomy. We aim to conduct a single-arm meta-analysis of the SASI bypass to explore its moderate-term efficacy, as this might expand the available choices for surgeons to choose the best bariatric surgery that suits the patient's condition. MATERIALS AND METHODS: We conducted a comprehensive search on PubMed, Scopus, EMBASE, and Cochrane to identify studies for the SASI bypass surgery focusing on outcomes such as %EWL, %TWL, remission rate of comorbidities, and complications. The statistical analysis was carried out using RStudio version 4.3.2. Heterogeneity was assessed using the Cochrane Q test and I2 statistics. RESULTS: Our findings illuminate SASI's potency by undertaking a single-arm meta-analysis involving 1873 patients across 26 studies. At 12 months, we report a noteworthy % Excess Weight Loss (%EWL) (Mean 84.13; 95% CI 78.41-89.85; I2 = 95%), and % Total Weight Loss (%TWL) (Mean 35.17; 95% CI 32.30-38.04; I2 = 97%), highlighting SASI's efficacy on weight loss. Cumulative meta-analyses supported these findings. More weight loss was observed with a 250 cm common limb and a greater than 3 cm anastomosis. An 88.28% remission rate in type 2 diabetes mellitus (95% CI 79.74-95.03; I2 = 84%) at 12 months was observed. Beyond weight outcomes, SASI impacts comorbidities with a good safety profile. CONCLUSION: Our study positions the SASI bypass as a good alternative option. However, long-term efficacy is yet to be explored in the future.

Performance and oncologic safety of sentinel lymph node biopsy after neoadjuvant chemotherapy: Results from a tertiary care center in Lebanon.

BACKGROUND: The feasibility of sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NACT) in initially node-positive patients is still controversial. We aim to evaluate the oncologic outcomes of SLNB after NACT and further compare the results between those who were initially node-negative and node-positive. METHODS: This is a retrospective cohort that included patients diagnosed with invasive breast cancer and had surgical management between January 2010 and December 2016. Survival and recurrence data after 3-5 years were collected from patients' records. We divided patients into Group A who were initially node-negative and had SLNB ± axillary lymph node dissection (ALND) and Group B who were node-positive and had SLNB ± ALND. RESULTS: Among initially node-negative patients, 43 out of 63 patients did SLNB (Group A). However, among initially node-positive patients only 28 out of 123 patients did SLNB (Group B). Out of the 71 patients who did SLNB after NACT, 26 patients had positive SLNs with only 14 patients who further underwent ALND. The identification rate of SLNB was 100% in Group A and 96.4% in Group B. The survival curves by nodal status showed no significant difference between overall survival and recurrence-free survival at 5 years between patients in Group A versus Group. CONCLUSION: The results suggest that in properly selected patients, SLNB can be feasible after NACT. Our results resemble the reported literature on accuracy of SLNB after NACT and adds to the growing pool of data on this topic.

Global burden of metabolic diseases, 1990-2021.

BACKGROUND: Common metabolic diseases, such as type 2 diabetes mellitus (T2DM), hypertension, obesity, hypercholesterolemia, and metabolic dysfunction-associated steatotic liver disease (MASLD), have become a global health burden in the last three decades. The Global Burden of Disease, Injuries, and Risk Factors Study (GBD) data enables the first insights into the trends and burdens of these metabolic diseases from 1990 to 2021, highlighting regional, temporal and differences by sex. METHODS: Global estimates of disability-adjusted life years (DALYs) and deaths from GBD 2021 were analyzed for common metabolic diseases (T2DM, hypertension, obesity, hypercholesterolemia, and MASLD). Age-standardized DALYs (mortality) per 100,000 population and annual percentage change (APC) between 1990 and 2021 were estimated for trend analyses. Estimates are reported with uncertainty intervals (UI). RESULTS: In 2021, among five common metabolic diseases, hypertension had the greatest burden (226 million [95 % UI: 190-259] DALYs), whilst T2DM (75 million [95 % UI: 63-90] DALYs) conferred much greater disability than MASLD (3.67 million [95 % UI: 2.90-4.61]). The highest absolute burden continues to be found in the most populous countries of the world, particularly India, China, and the United States, whilst the highest relative burden was mostly concentrated in Oceania Island states. The burden of these metabolic diseases has continued to increase over the past three decades but has varied in the rate of increase (1.6-fold to 3-fold increase). The burden of T2DM (0.42 % [95 % UI: 0.34-0.51]) and obesity (0.26 % [95 % UI: 0.17-0.34]) has increased at an accelerated rate, while the rate of increase for the burden of hypertension (-0.30 % [95 % UI: -0.34 to -0.25]) and hypercholesterolemia (-0.33 % [95 % UI: -0.37 to -0.30]) is slowing. There is no significant change in MASLD over time (0.05 % [95 % UI: -0.06 to 0.17]). CONCLUSION: In the 21st century, common metabolic diseases are presenting a significant global health challenge. There is a concerning surge in DALYs and mortality associated with these conditions, underscoring the necessity for a coordinated global health initiative to stem the tide of these debilitating diseases and improve population health outcomes worldwide.

Robot-Assisted Heller Myotomy Versus Laparoscopic Heller Myotomy: A Systematic Review and Meta-Analysis.

Robot-assisted Heller myotomy (RAHM) is an increasingly popular alternative to the traditional laparoscopic Heller myotomy (LHM) in the surgical management of achalasia, with similar outcomes and potentially lower complication rates. We aimed to systematically review the literature by comparing the technical success, outcomes, and complications of RAHM and LHM. We searched PubMed, Medline, and Cochrane Central Register for articles published between 2001 and 2023. Data on technical success, clinical outcomes, length of hospital stay, esophageal perforation rate, and overall mortality were extracted. A total of 11 articles were included in the study, comparing a total of 3,543 RAHM and 15,434 LHM cases. The mean operative time was significantly higher in the RAHM procedure with a total mean difference of 23.95 (95% confidence interval (Cl) 17.09, 30.81; p < 0.00001; I2 = 99%). However, the RAHM was associated with a significantly shorter hospital stay, with a total mean difference of -0.24 (95% Cl = -0.40, -0.08; p < 0.00001; I2 = 81%). The volume of blood loss was significantly smaller in RAHM with a total mean difference of -61.11 (95% CI = -150.31, 28.09; p < 0.00001; I2 = 99%). Esophageal mucosal perforation was significantly lower in RAHM with an odds ratio of 0.36 (95% CI = 0.16, 0.82; p = 0.02; I2 = 22%). Both procedures were associated with similar rates of symptom relief. Although no mortality was recorded in patients who underwent RAHM as opposed to 16 cases in patients who underwent LHM, no statistically significant difference could be reached. Our results demonstrate that while both procedures yield comparable clinical outcomes, RAHM is associated with a lower overall complication rate, particularly a lower rate of esophageal mucosal perforation, shorter hospital stay, and possibly a lower mortality rate. This confirms that RAHM is a viable and justifiable alternative to the conventional LHM in the surgical management of achalasia.

Single Incision Versus Conventional Multiport Laparoscopic Sleeve Gastrectomy: Meta-Analysis and Systematic Review.

Laparoscopic sleeve gastrectomy (LSG) is the most widely performed bariatric surgery and has been associated with excellent outcomes and a significant reduction in obesity-related morbidity and mortality. Traditionally, this surgery is performed using five to seven trocars. However, LSG performed through a single trocar is emerging as a less invasive method of performing this surgery. This systematic review and meta-analysis compare the outcomes and complication rates of single-port versus multi-port LSG. We searched PubMed, Medline, Scopus, and the Cochrane Library for articles published from 2008 to 2023, in accordance with the PRISMA 2020 guidelines. Data on variables such as operative time, excess weight loss, intraoperative bleeding, postoperative leak, and incisional hernia rates were collected and analyzed using a random-effects model. Fourteen articles met the inclusion criteria and were included in the meta-analysis. No significant differences were found between the single-port LSG (SILSG) and conventional LSG (CLSG) groups in terms of operative time, rate, intraoperative complications, length of hospital stay, postoperative complications, and excess weight loss (EWL). Furthermore, single incision sleeve gastrectomy showed better satisfaction with the cosmetic score. SILSG is a viable alternative procedure, showing comparable outcomes to multiport conventional sleeve gastrectomy, in addition, to a better cosmetic satisfaction score.

Roux-en-Y Gastric Bypass Versus One Anastomosis Gastric Bypass as Revisional Surgery After Failed Sleeve Gastrectomy: A Systematic Review and Meta-analysis.

Purpose: This study aimed to assess the outcomes of revisional procedures, namely Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) following unsuccessful laparoscopic sleeve gastrectomy. Materials and Methods: This systematic review and meta-analysis included 817 patients (404 in OAGB group, 413 in RYGB group) from seven retrospective comparative studies. Data on sample size, demographics, perioperative complications, operative time, pre- and post-revisional body mass index, total weight loss, and global weight loss over follow-up were extracted. Results: The mean operative time was 98.2-201 minutes for RYGB versus 78.7-168 minutes for OAGB. Despite classical RYGB gastric bypass taking longer, mini gastric bypass resulted in greater weight loss than RYGB, with a mean difference of -5.84 (95% confidence interval [CI], -6.74 to -4.94; P<0.00001; I2=0%), greater total weight loss, and a higher diabetes remission rate (odds ratio [OR], 0.32; 95% CI, 0.14 to 0.71). However, OAGB was associated with a significantly higher incidence of postoperative gastroesophageal reflux than RYGB (52 vs. 31: OR, 0.40; 95% CI, 0.24 to 0.67; P=0.0005; I2=0%). Conclusion: OAGB was performed more quickly and boasted greater total weight loss and higher diabetes remission rates compared to RYGB after failed sleeve gastrectomy. However, OAGB also demonstrated a higher incidence of postoperative gastroesophageal reflux disease. Thus, careful patient selection is essential when considering OAGB. Trial Registration: PROSPERO Identifier: CRD42023474966.

Single Anastomosis Duodeno-Ileal Bypass (SADI) as a Second Step After Failed Sleeve Gastrectomy: Systematic Review and Meta-analysis.

Purpose: Our aim in this study is to assess single anastomosis duodeno-ileal bypass (SADI) as a salvage procedure following sleeve gastrectomy (SG), examining its technical feasibility, outcomes, and potential complications. Materials and Methods: A systematic review and meta-analysis were conducted, drawing data from PubMed, Medline, and the Cochrane library. The analysis encompassed 14 studies, involving 1,066 patients. We evaluated operative time, comorbidity resolution (hypertension, dyslipidemia, diabetes), post-operative diarrhea incidence, excess weight loss (EWL) at six, twelve, and twenty-four months, and post-operative leak rates. Results: SADI as a salvage procedure following SG yielded positive outcomes. Mean operative time was 125.98 minutes (95% CI 102.50-149.46, I2=99%). Importantly, SADI led to comorbidity resolution in a notable proportion of cases: hypertension in 48% (95% CI 38-57%, I2=44%), dyslipidemia in 55% (95% CI 40-69%, I2=30%), and diabetes in 63% (95% CI 53-72%, I2=30%) of patients. Post-operative diarrhea incidence was relatively low at 2% (95% CI 1-9%, I2=75%). In terms of weight loss, SADI patients exhibited substantial EWL: 47.73% (95% CI 37.86-57.61, I2=95%) at six months, 59.39% (95% CI 51.18-67.61, I2=95%) at twelve months, and 23.84% (95% CI 5.76-41.92, I2=100%). At twenty-four months. Furthermore, post-operative leak rate was relatively low, reported in only 1% (95% CI 0-5%, I2=80%) of cases. Conclusion: SADI as a salvage procedure post-SG demonstrates technical feasibility and marked effectiveness. It offers substantial comorbidity resolution, significant weight loss, and low post-operative complication rates, notably post-operative leaks. Further research should investigate the long-term impact of SADI on patient nutritional status to facilitate its broader adoption.

Robotic versus laparoscopic revisional bariatric surgeries: a systematic review and meta-analysis.

Purpose: In recent years, the need for revisional bariatric surgery (RBS) procedures has experienced a noteworthy surge to confront complexities and weight recidivism. Despite being a subject of controversy for many, the utilization of the Da Vinci robotic platform (Intuitive Surgical, Inc.) may present benefits in RBS. This study aimed to evaluate the outcomes of robotic RBS in comparison to Laparoscopic RBS. Methods: A meticulous and thorough analysis was ensured through a comprehensive exploration of the literature, which included PubMed, Medline, Scopus, and Cochrane. This exploration was conducted in adherence to the directives outlined in the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The Newcastle-Ottawa scale was used for quality assessment. Results: A total of 11 studies were included in this meta-analysis, comprising 55,889 in the laparoscopic group and 5,809 in the robotic group. No significant differences were observed in the leak, bleeding, operative time, or length of stay across both groups. However, the robotic group showed higher rates of conversion to open surgery (odds ratio [OR], 0.65; 95% confidence interval [CI], 0.53-0.79; p < 0.0001; I2 = 0%), reoperation (OR, 0.70; 95% CI, 0.57-0.87; p = 0.0009; I2 = 6%), and readmission (higher rate of readmission in the robotic group; OR, 0.76; 95% CI, 0.62-0.92; p = 0.005; I2 = 30%). Conclusion: Robotic-assisted bariatric surgery has no significant advantage over conventional laparoscopic surgery. Further research is warranted to explore and evaluate surgeons' methodology and proficiency differences.

Indirect ballistic injury to the liver resulting in retained bullet complicated with hepatic abscess: a case report.

Indirect and extraperitoneal penetrating liver injury is an extremely uncommon phenomenon. In this report, we highlight the case of an 18-year-old male patient that sustained a gunshot wound with an entry site through the right buttock and landed in the liver. He presented to us in sepsis due to developing a hepatic abscess at the site of the dislodged bullet that was confirmed with computed tomography. Interestingly, the ballistic missile did not cause any visceral injury due to its indirect and extraperitoneal trajectory. The patient underwent diagnostic laparoscopy, where the hepatic abscess was unroofed and evacuated. A free-floating bullet was found and extracted, and a small bile duct leak was repaired. The patient had an uneventful post-operative course and was duly discharged on an empiric course of antibiotics.

Management of ruptured hepatocellular carcinoma invading the gastrointestinal tract: A case report.

INTRODUCTION AND IMPORTANCE: Hepatocellular carcinoma (HCC) constitutes most of primary liver cancers. HCC invading the gastrointestinal tract (GIT) is considered a rare entity with limited reports in the literature. Management can either be palliative or curative such as transarterial chemoembolization (TACE) followed by definitive resection. Here, we present a case of direct HCC invasion of the GIT that was managed by surgical resection. CASE PRESENTATION: A 74-year-old male with a history of a liver mass, found to have HCC. Admitted for medical optimization prior to definitive resection, however his stay was complicated by hemorrhagic shock, with imaging findings of hemoperitoneum suggestive of spontaneous rupture of the mass. TACE was done to stabilize the patient prior to resection. Patient was taken immediately to the operating room for definitive resection. CLINICAL DISCUSSION: Most cases of direct HCC invasion into the GI tract present mainly with GI bleed. Some patients, present with abdominal pain without any warning signs of an occult GI bleed. Thus, absence of an occult GI bleeding does not exclude a GIT invasion. Management options are several, but in advanced stages, management is not limited to palliation. CONCLUSION: GIT invasion is a rare complication of HCC reported in scarcity in the literature. Most cases present with GI bleeding but with some rare cases, they present with more generalized symptoms like abdominal pain, weight loss or fatigue. Despite having a poor prognosis, complete surgical resection of the tumor may be a reassuring and life prolonging treatment option for these patients.

Primary squamous cell carcinoma of the colon: A rare case report.

INTRODUCTION AND IMPORTANCE: Squamous cell carcinoma (SCC) of the colon is an extremely rare pathologic entity, accounting for less than 1 % of all colorectal cancer cases. They tend to be very aggressive with poor outcomes and treatment strategies are still controversial due to the paucity of data available to guide management. CASE PRESENTATION: A case of a cecal mass with metastatic liver lesions. Initially diagnosed as an adenocarcinoma, the patient underwent resection with metastasectomy. Despite achieving negative surgical margins and undergoing adjuvant chemotherapy, the patient relapsed and presented with a new mass in the descending colon. The patient underwent resection with subsequent follow-up revealing distant metastasis. The patient passed away soon after. CLINICAL DISCUSSION: Primary colorectal SCC has similar presentation to adenocarcinoma of the colon. Unfortunately, it usually presents at a late stage. Diagnosis of colorectal SCC requires histologic confirmation of SCC plus exclusion of possible causes. Management is predominantly definitive radical resection followed by adjuvant chemotherapy and radiotherapy. Surgical margins should be at least 5 cm, preferably 10 cm. Lymph node yield greater than 20 was associated with improved survival. Studies assessing the prognosis of primary colorectal SCC following chemo-radiotherapy have not been done. CONCLUSION: Surgery remains the most vital important step in the management of colonic SCC. The role of chemotherapy and/or radiation remains questionable. Depending on the aggressiveness of this disease the need for further frequent.

The implications and management of complex biliary injuries at a tertiary hepatobiliary specialty center.

Injuries of the biliary tract and complex injuries involving vascular and parenchymal tissue can be detrimental despite the improved use of laparoscopy. Complex biliary injuries are variable depending on the type of injury as well as patient and surgeon factors. We present four cases of complex biliary injuries at our tertiary referral center with hepatobiliary expertise: biliary stenosis with obstruction, double duct system anatomy, combined right hepatic arterial transection and biliary duct injury, and a complete pedicle injury. Early identification and specialized repair of complex biliary injuries is essential to minimize patient morbidity. Notably, consulting a specialist intraoperatively in case of difficult dissection and visualization or a suspected injury and considering bail-out strategies such as a subtotal cholecystectomy or conversion are safe approaches to minimize complex biliary injuries. Earlier recognition and repair of complex biliary injuries improves outcomes when immediate intraoperative repair can be performed rather than delayed postoperatively.

Long-term results of endovenous laser ablation of saphenous vein reflux: Up to nine years of follow-up.

INTRODUCTION: Endovenous laser ablation (EVLA) has become the gold standard for the treatment of saphenous vein reflux. We report the long-term clinical and ultrasound results of EVLA. METHODS: This study is a retrospective review of patients who underwent EVLA of saphenous vein over four years. Clinical results were assessed using venous clinical severity score (VCSS), and ultrasound results were classified according to Bush classification. RESULTS: Over a median follow-up time of 4.4 years, 168 EVLA-treated patients showed a drop in VCSS from 4.38 to 1.39. Ultrasound results of 140 treated great saphenous veins showed that 64% had one or more cause of recurrence. The presence of neovascularization correlated well with the lack of improvement of VCSS. CONCLUSION: EVLA resulted in drop in VCSS from 4.38 to 1.39. Among 140 treated great saphenous veins, reflux in the anterior accessory saphenous vein was the primary cause (23.5%) of recurrence.
