RESUMO

Current guidelines recommend neoadjuvant (NAC) and/or adjuvant chemotherapy for locally advanced gastric cancers (LAGCs). However, the choice and duration of NAC regimen is standardized, rather than personalized to biologic response, despite the availability of several different classes of agents for the treatment of gastric cancer (GC). The current trial will use a tumor-informed ctDNA assay (Signatera™) and monitor response to NAC. Based on ctDNA kinetics, the treatment regimen is modified. This is a prospective single center, single-arm, open-label study in clinical stage IB-III GC. ctDNA is measured at baseline and repeated every 8 weeks. Imaging is performed at the same intervals. The primary end point is the feasibility of this approach, defined as percentage of patients completing gastrectomy.

RESUMO

BACKGROUND: BMI is a risk factor for recurrence and post-operative complications in both open and laparoscopic totally extraperitoneal approach (TEP) repair. Robotic surgery using the transabdominal preperitoneal approach (TAPP) is a safe and viable option for inguinal hernia repair (IHR). The objective of this study is to determine how difference in BMI influences rate of operative time, complications, and rate of recurrence in a robotic TAPP IHR. METHODS: We performed a retrospective review of patients who underwent robotic inguinal hernia repair between 2012 and 2019 at a Veterans Health Administration facility (N = 304). The operating time, outcomes, and overall morbidity and mortality for robotic IHR were compared between three different BMI Groups. These groups were divided into: "Underweight/Normal Weight" (BMI < 25) n = 102, "Pre-Obese" (BMI 25-29.9) n = 120, and "Obese" (BMI 30 +) n = 82. RESULTS: The average operating time of a bilateral IHR by BMI group was 83.5, 98.4, and 97.8 min for BMIs < 25, 25-29.9, and 30 +, respectively. Operating time was lower in the Underweight/Normal BMI group compared to the Pre-Obese group (p = 0.006) as well as the Obese group (p = 0.001). For unilateral repair, the average operation length by group was 65.2, 70.9, and 85.6 min for BMIs < 25, 25-29.9, and 30 +, respectively, demonstrating an increased time for Obese compared to Underweight/Normal BMI (p = 0.001) and for Obese compared to Pre-Obese (p = 0.01). Demographic/comorbidity variables were not significantly different, except for a higher percentage of white patients in the Underweight/Normal BMI group compared to the Pre-Obese and Obese groups (p = 0.02 and p = 0.0003). There was no significant difference in complications or recurrence. CONCLUSION: BMI has a significant impact on the operating time of both unilateral and bilateral robotic hernia repair. Despite this increased operative time, BMI group did not differ significantly in postoperative outcomes or in recurrence rates.

RESUMO

BACKGROUND: Hiatal Hernia Repairs (HHR) are performed by both general surgeons (GS) and thoracic surgeons (TS). However, there are limited literature with respect to outcomes of HHR based on specialty training. The objective of this study was to compare the utilization, perioperative outcomes, and cost for HHR performed by GS versus TS. METHODS: The Vizient database was used to identify patients who underwent elective laparoscopic HHR between October 2014 and June 2018. Patients were grouped according to surgeon's specialty (GS vs. TS). Patient demographics and outcomes including in-hospital mortality were compared between groups. RESULTS: During the study period 13,764 patients underwent HHR by either GS or TS. GS performed 9930 (72%) cases while TS performed 3834 (28%) cases. There was no significant difference between GS versus TS with regard to serious morbidity (1.28% vs. 1.30%, p = 0.97) or mortality (0.10% vs. 0.21%, p = 0.19). The mortality index was 0.24 for GS versus 0.45 for TS. Compared to TS, laparoscopic HHR performed by GS was associated with a shorter LOS (2.57 days vs. 2.72 days, p < 0.001) and lower mean hospital costs ($7139 vs. $8032, p < 0.0001). CONCLUSIONS: Within the context of academic centers, laparoscopic HHRs are mostly performed by GS with comparable outcome between general versus thoracic surgeons.

RESUMO

BACKGROUND: Laparoscopic sleeve gastrectomy has become the procedure of choice for the treatment of morbid obesity. Robotic sleeve gastrectomy is an alternative surgical option, but its utilization has been low. The aim of this study was to evaluate the contemporary outcomes of robotic sleeve gastrectomy (RSG) versus laparoscopic sleeve gastrectomy (LSG) using a national database from accredited bariatric centers. STUDY DESIGN: Using the 2015 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, clinical data for patients who underwent RSG or LSG were examined. Emergent and revisional cases were excluded. A multivariate logistic regression model was utilized to compare the outcomes between RSG and LSG. RESULTS: A total of 75,079 patients underwent sleeve gastrectomy with 70,298 (93.6%) LSG and 4781 (6.4%) RSG. Preoperative sleep apnea and hypoalbumenia were significantly higher in the RSG group (P < 0.01). Mean length of stay was similar between RSG and LSG (1.8 ± 2.0 vs. 1.7 ± 2.0 days, P = 0.17). Operative time was longer in the RSG group (102 ± 43 vs. 74 ± 36 min, P < 0.01). There was no significant difference in 30-day mortality between the RSG versus LSG group (0.02% vs. 0.01%, AOR 0.85; 95% CI 0.11-6.46, P = 0.88). However, RSG was associated with higher serious morbidity (1.1% vs. 0.8%, AOR 1.40; 95% CI 1.05-1.86, P < 0.01), higher leak rate (1.5% vs. 0.5%, AOR 3.14; 95% CI 2.65-4.42, P < 0.01), and higher surgical site infection rate (0.7% vs. 0.4%, AOR 1.55; 95% CI 1.08-2.23, P = 0.01). CONCLUSIONS: Robotic sleeve gastrectomy has longer operative time and is associated with higher postoperative morbidity including leak and surgical site infections. Laparoscopy should continue to be the surgical approach of choice for sleeve gastrectomy.

RESUMO

Obesity is linked to the development and progression of CKD, but whether bariatric surgery protects against CKD is poorly understood. We, therefore, examined whether bariatric surgery influences CKD risk. The study included 2144 adults who underwent bariatric surgery from March of 2006 to April of 2009 and participated in the Longitudinal Assessment of Bariatric Surgery-2 Study cohort. The primary outcome was CKD risk categories as assessed by the Kidney Disease Improving Global Outcomes (KDIGO) consortium criteria using a combination of eGFR and albuminuria. Patients were 79% women and 87% white, with a median age of 46 years old. Improvements were observed in CKD risk at 1 and 7 years after surgery in patients with moderate baseline CKD risk (63% and 53%, respectively), high baseline risk (78% and 56%, respectively), and very high baseline risk (59% and 23%, respectively). The proportion of patients whose CKD risk worsened was ≤10%; five patients developed ESRD. Sensitivity analyses using year 1 as baseline to minimize the effect of weight loss on serum creatinine and differing eGFR equations offered qualitatively similar results. Treatment with bariatric surgery associated with an improvement in CKD risk categories in a large proportion of patients for up to 7 years, especially in those with moderate and high baseline risk. These findings support consideration of CKD risk in evaluation for bariatric surgery and further study of bariatric surgery as a treatment for high-risk obese patients with CKD.

RESUMO

We sought to assess whether laparoscopic anti-reflux surgery (LARS) is associated with decreased rates of disease progression in patients with idiopathic pulmonary fibrosis (IPF).The study was a retrospective single-centre study of IPF patients with worsening symptoms and pulmonary function despite antacid treatment for abnormal acid gastro-oesophageal reflux. The period of exposure to LARS was September 1998 to December 2012. The primary end-point was a longitudinal change in forced vital capacity (FVC) % predicted in the pre- versus post-surgery periods.27 patients with progressive IPF underwent LARS. At time of surgery, the mean age was 65 years and mean FVC was 71.7% pred. Using a regression model, the estimated benefit of surgery in FVC % pred over 1 year was 5.7% (95% CI -0.9-12.2%, p=0.088) with estimated benefit in FVC of 0.22 L (95% CI -0.06-0.49 L, p=0.12). Mean DeMeester scores decreased from 42 to 4 (p<0.01). There were no deaths in the 90 days following surgery and 81.5% of participants were alive 2 years after surgery.Patients with IPF tolerated the LARS well. There were no statistically significant differences in rates of FVC decline pre- and post-LARS over 1 year; a possible trend toward stabilisation in observed FVC warrants prospective studies. The ongoing prospective randomised controlled trial will hopefully provide further insights regarding the safety and potential efficacy of LARS in IPF.

RESUMO

IMPORTANCE: The variability and durability of improvements in pain and physical function following Roux-en-Y gastric bypass (RYGB) or laparoscopic adjustable gastric banding (LAGB) are not well described. OBJECTIVES: To report changes in pain and physical function in the first 3 years following bariatric surgery, and to identify factors associated with improvement. DESIGN, SETTING, AND PARTICIPANTS: The Longitudinal Assessment of Bariatric Surgery-2 is an observational cohort study at 10 US hospitals. Adults with severe obesity undergoing bariatric surgery were recruited between February 2005 and February 2009. Research assessments were conducted prior to surgery and annually thereafter. Three-year follow-up through October 2012 is reported. EXPOSURES: Bariatric surgery as clinical care. MAIN OUTCOMES AND MEASURES: Primary outcomes were clinically meaningful presurgery to postsurgery improvements in pain and function using scores from the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) (ie, improvement of ≥5 points on the norm-based score [range, 0-100]) and 400-meter walk time (ie, improvement of ≥24 seconds) using established thresholds. The secondary outcome was clinically meaningful improvement using the Western Ontario McMaster Osteoarthritis Index (ie, improvement of ≥9.7 pain points and ≥9.3 function points on the transformed score [range, 0-100]). RESULTS: Of 2458 participants, 2221 completed baseline and follow-up assessments (1743 [78.5%] were women; median age was 47 years; median body mass index [BMI] was 45.9; 70.4% underwent RYGB; 25.0% underwent LAGB). At year 1, clinically meaningful improvements were shown in 57.6% (95% CI, 55.3%-59.9%) of participants for bodily pain, 76.5% (95% CI, 74.6%-78.5%) for physical function, and 59.5% (95% CI, 56.4%-62.7%) for walk time. Additionally, among participants with severe knee or disability (633), or hip pain or disability (500) at baseline, approximately three-fourths experienced joint-specific improvements in knee pain (77.1% [95% CI, 73.5%-80.7%]) and in hip function (79.2% [95% CI, 75.3%-83.1%]). Between year 1 and year 3, rates of improvement significantly decreased to 48.6% (95% CI, 46.0%-51.1%) for bodily pain and to 70.2% (95% CI, 67.8%-72.5%) for physical function, but improvement rates for walk time, knee and hip pain, and knee and hip function did not (P for all ≥.05). Younger age, male sex, higher income, lower BMI, and fewer depressive symptoms presurgery; no diabetes and no venous edema with ulcerations postsurgery (either no history or remission); and presurgery-to-postsurgery reductions in weight and depressive symptoms were associated with presurgery-to-postsurgery improvements in multiple outcomes at years 1, 2, and 3. CONCLUSIONS AND RELEVANCE: Among a cohort of participants with severe obesity undergoing bariatric surgery, a large percentage experienced improvement, compared with baseline, in pain, physical function, and walk time over 3 years, but the percentage with improvement in pain and physical function decreased between year 1 and year 3.

RESUMO

BACKGROUND: The US News & World Report (USNWR) annual ranking of the best hospitals for gastroenterology and gastrointestinal surgery offers direction to patients and healthcare providers, especially for recommendations on complex medical and surgical gastrointestinal (GI) conditions. The objective of this study was to examine the outcomes of complex GI cancer resections performed at USNWR top-ranked, compared to non-ranked, hospitals. STUDY DESIGN: Using the Vizient database, data for patients who underwent esophagectomy, gastrectomy, and pancreatectomy for malignancy between January and December 2018 were reviewed. Perioperative outcomes were analyzed according to USNWR rank status. Primary outcome was in-hospital mortality. Secondary outcomes include length of stay, mortality index (observed-to-expected mortality ratio), rate of serious complication, and cost. Secondary analysis was performed for outcomes of patients who developed serious complications. RESULTS: There were 3,054 complex GI cancer resections performed at 42 top-ranked hospitals vs 3,608 resections performed at 198 non-ranked hospitals. The mean annual case volume was 73 cases at top-ranked hospitals compared to 18 cases at non-ranked hospitals. Compared with non-ranked hospitals, top-ranked hospitals had lower in-hospital mortality (0.96% vs 2.26%, respectively, p < 0.001) and lower mortality index (0.71 vs 1.53, respectively). There were no significant differences in length of stay, rate of serious complications, or direct cost between groups. In patients who developed serious morbidity, top-ranked hospitals had a lower mortality compared with non-ranked hospitals (8.2% vs 16.8%, respectively, p < 0.01). CONCLUSIONS: Within the context of complex GI cancer resection, USNWR top-ranked hospitals performed a 4-fold higher case volume and were associated with improved outcomes. Patients with complex GI-related malignancies may benefit from seeking surgical care at high-volume regional USNWR top-ranked hospitals.

RESUMO

BACKGROUND: Transoral incisionless fundoplication (TIF) is an endoscopic alternative for the treatment of GERD. However, TIF does not address the hiatal hernia (HH). We present a novel approach with a laparoscopic HH repair followed by same-session TIF, coined concomitant transoral incisionless fundoplication (cTIF). The aim of this study was to assess the efficacy, safety, and feasibility of cTIF in a collaborative approach between Gastroenterology and surgery. STUDY DESIGN: Patients with confirmed GERD and >2 cm HH who underwent cTIF between 2018 and 2020 were included. Symptoms were assessed using the Reflux Disease Questionnaire, GERD Health-Related Quality of Life Index, and the Reflux Symptom Index pre and post cTIF. One-way ANOVA and paired samples t-test were used for statistical analysis. RESULTS: Sixty patients underwent cTIF (53% were men, mean age was 59.3 years) with 100% technical success. Mean ± SD HH measurement on endoscopy was 2.9 ± 1.5 cm. Scores on Reflux Disease Questionnaire for symptom frequency and symptom severity improved significantly from before to 6 months after cTIF (17.4 to 4.72; p < 0.01 and 16.7 to 4.56; p < 0.05, respectively). According to the GERD Health-Related Quality of Life Index, significant decreases were seen post cTIF in heartburn (23.26 to 7.37; p < 0.01) and regurgitation (14.26 to 0; p = 0.05). Reflux Symptom Index similarly decreased after cTIF (17.7 to 8.1 post cTIF; p < 0.01). Mean DeMeester score decreased from 43.7 to 4.9 and acid exposure time decreased from 12.7% to 1.28% post cTIF (p = 0.06). CONCLUSIONS: We present a novel multidisciplinary approach to GERD using a combined endoscopic and surgical approach with close collaboration between Gastroenterology and surgery. Our results suggest that cTIF is safe and effective in reducing reflux symptoms in a large spectrum of GERD patients.

RESUMO

PURPOSE: Proximal colon cancers are more likely to present with advanced stage than distal cancers; however, previous reports conflict regarding the independent prognostic significance of tumor location on survival. We examined survival by colon cancer subsite location by use of data from the California Cancer Registry. METHODS: An analysis of colon cancer cases from 1994 to 2004 was conducted, with follow-up through 2006. Colon subsite location was defined as proximal colon (cecum, ascending colon, hepatic flexure), transverse colon, descending colon (splenic flexure, descending colon), and sigmoid colon. Subsite-specific survival analyses were conducted with use of the Kaplan-Meier method and Cox proportional hazards ratios. RESULTS: A total of 82,926 colon cancer cases were identified, including 40,078 proximal (48%), 8,023 transverse (10%), 8,657 descending (10%), and 26,168 sigmoid cancers (32%). A larger proportion of sigmoid cancers (30.5%) presented as Stage I compared with proximal (18.5%), transverse (16.8%), or descending colon cancers (20.1%). Proximal cancers had the greater proportion with high tumor grade (27%), and had a greater mean number of lymph nodes examined. There were no differences in treatment rendered when each colon subsite was stratified by stage. After adjustment for stage, grade, treatment, lymph node examination, and other relevant clinical variables, sigmoid cancers had decreased colorectal cancer-specific mortality compared with proximal tumors (hazards ratio = 0.88; 95% confidence interval, 0.85-0.92). CONCLUSIONS: In this analysis, sigmoid colon cancers were observed to have earlier stage, lower tumor grade, and independently decreased colorectal cancer-specific mortality compared with proximal tumors.

RESUMO

BACKGROUND: Morbidly obese patients often have impaired respiratory mechanics leading to restrictive and obstructive lung diseases. Weight loss after bariatric surgery has been shown to improve or resolve many obesity-related comorbidities. However, few studies have examined long-term changes in pulmonary mechanics after bariatric surgery. We hypothesize that pulmonary function improves after surgically induced weight loss. METHODS: We examined the pulmonary function of 104 morbidly obese patients who underwent laparoscopic gastric bypass or gastric banding. Pulmonary studies, including forced expiratory volume in 1 s (FEV(1)), forced vital capacity (FVC), peak expiratory flow (PEF), and forced expiratory volume at midexpiratory phase (FEV(25-75%)) were measured preoperatively and at 3-month intervals. All results are expressed as a percentage of the baseline values. RESULTS: There were 80 females and 24 males with a mean age of 41 years. The mean body mass index was 48 kg/m(2). The mean percentage of excess body weight loss at 12 months was 54%. At 12 months postoperatively, restrictive pulmonary mechanics significantly improved as demonstrated by an increase in the FEV(1) to 112% of baseline value, increase in the FVC to 109% of baseline value, increase in the PEF to 115% of baseline value, and increase in the FEV(25-75%) to 130% of baseline value. Additionally, the percentage of patients with obstructive lung pattern (FEV(1)/FVC ratio less than 0.8) decreased from 9.6% preoperatively to 1.9% postoperatively (p=0.03). CONCLUSIONS: Weight loss after laparoscopic gastric bypass significantly improves restrictive and obstructive respiratory mechanics. The improvements were observed as early as 3 months postoperatively.

RESUMO

INTRODUCTION: Gastric cardia cancer with involvement of the esophagus may require an esophagogastrectomy to obtain negative tumor margins. Multiple studies have shown that minimally invasive esophagectomy is a safe approach for the treatment of esophageal cancer [1-3]. We describe the technique of a minimally invasive Ivor-Lewis esophagectomy in a 55-year-old patient with a gastric cardia tumor. METHODS: In the laparoscopic phase, diagnostic laparoscopy was negative for metastasis. The stomach and distal esophagus were mobilized. The stomach was divided distal to the tumor and a thin gastric conduit was created. The specimen was removed through an extended abdominal port. In the thoracoscopic phase, the esophagus was mobilized. To ensure adequate proximal margins the esophageal stump was divided 1 cm below the azygous vein. A gastroesophageal anastomosis was created using a circular stapler. RESULTS: Total operative time was 210 min (laparoscopic time, 135 min; thoracoscopic time, 75 min). There were no intraoperative complications. Tumor margins were negative and there were 44 lymph nodes harvested. On postoperative day 2 the patient was transferred to the surgical floor and started on enteral feeds. On postoperative day 4 the esophagram was negative for leaks or obstruction. Patient was started on an oral diet and discharged on postoperative day 5. Final pathology revealed a T3N1M0 (stage III) gastric cardia tumor. The patient underwent adjuvant chemoradiation therapy and at 15 months postoperatively the patient was recurrence free. CONCLUSION: We recently reported our experience with 104 minimally invasive esophagectomy procedures, of which seven patients had a diagnosis of gastric cardia cancer [4]. The mean number lymph nodes harvested was 23 ± 12. Minimally invasive Ivor-Lewis esophagogastrectomy for the treatment of gastric cardia cancer is technically feasible and safe for large gastric cardia tumors.

RESUMO

Studies have shown conflicting data with regard to the volume and outcome relationship for gastrectomy. Using the University HealthSystem Consortium national database, we examined the influence of the hospital's volume of gastrectomy on outcomes at academic centers between 2004 and 2008. Outcome measures, including length of stay, 30-day readmission, morbidity, and in-hospital mortality, were compared among high- (13 or greater), medium- (6 to 12), and low-volume (five or less) hospitals. There were 10 high- (n = 593 cases), 36 medium- (n = 1076 cases), and 75 low-volume (n = 500 cases) hospitals. There were no significant differences between high- and low-volume hospitals with regard to length of stay, overall complications, 30-day readmission rate, and in-hospital mortality (2.4 vs 4.4%, respectively, P = 0.06). Despite the small number of gastrectomies performed at the low-volume hospitals, these same hospitals performed a large number of other types of gastric surgery such as gastric bypass for the treatment of morbid obesity (102 cases/year). Within the context of academic medical centers, lower annual volume of gastrectomy for neoplasm is not a predictor of poor outcomes which may be explained by the gastric operative experience derived from other types of gastric surgery.

RESUMO

Abdominoperineal resection (APR) after pelvic radiation can be complicated by an increased rate of difficult to treat perineal wound complications. In an effort to improve postoperative morbidity after APR, myocutaneous flap reconstructions have been used. We review our recent experience with APR with vertical rectus abdominis myocutaneous flap reconstruction (VRAM) after preoperative pelvic radiation. A retrospective review of patients who underwent APR with VRAM reconstruction after pelvic radiation from December 2004 to July 2008 was conducted. Outcome measures included demographics, comorbidities, length of stay, wound complications, and morbidity and mortality. Fifteen patients with a mean age of 61 +/- 9 years underwent APR with VRAM reconstruction. Five patients also required posterior vaginectomy with the APR. Indications for APR were rectal cancer (n = 14, 93%) and anal canal cancer (n = 1, 7%). There were no intraoperative complications. Mean estimated blood loss was 635 +/- 446 mL and mean intraoperative blood transfusion requirements were 1 +/- 2 units. Mean length of hospital stay was 11 +/- 4 days. Six (40%) patients had minor perineal wound complications. One (7%) patient had a perineal wound infection requiring reoperation with washout and reapproximation. There was no 30-day or in-hospital mortality. All VRAM flaps remained viable through follow-up. APR with VRAM flap reconstruction after preoperative pelvic radiation can be performed safely with limited wound complications and no mortality.

RESUMO

BACKGROUND: Gastroesophageal reflux disease (GERD) is commonly associated with morbid obesity. Laparoscopic fundoplication is a standard surgical treatment for GERD, and laparoscopic gastric bypass has been shown to effectively resolve GERD symptoms in the morbidly obese. We sought to compare the in-hospital outcomes of morbidly obese patients who underwent laparoscopic fundoplication for the treatment of GERD versus laparoscopic gastric bypass for the treatment of morbid obesity and related conditions, including GERD, at U.S. academic medical centers. METHODS: Using the "International Classification of Diseases, 9th Revision" procedural and diagnoses codes for morbidly obese patients with GERD, we obtained data from the University HealthSystem Consortium database for all patients who underwent laparoscopic fundoplication or laparoscopic gastric bypass from October 2004 to December 2007 (n=27,264). The outcome measures included the patient demographics, length of stay, in-hospital overall complications, mortality, risk-adjusted mortality ratio (observed to expected mortality), and hospital costs. RESULTS: Compared with the patients who underwent laparoscopic gastric bypass, those who underwent laparoscopic fundoplication had a lower severity of illness score (P<.05). The overall in-hospital complications were significantly lower in the laparoscopic gastric bypass group (P<.05). The mean length of stay, observed mortality, risk-adjusted mortality, and hospital costs were comparable between the 2 treatment groups. CONCLUSION: Laparoscopic gastric bypass is as safe as laparoscopic fundoplication for the treatment of GERD in the morbidly obese. Hence, morbidly obese patients with GERD should be referred for bariatric surgery evaluation and offered laparoscopic gastric bypass as a surgical option.

RESUMO

BACKGROUND: Laparoscopic adjustable gastric banding is gaining popularity in the United States. Our objective was to examine the use and outcomes of laparoscopic adjustable gastric banding at academic medical centers. METHODS: Using the "International Classification of Diseases, Ninth Revision" diagnosis and procedure codes, data were obtained from the University Health System Consortium Clinical Database for all laparoscopic adjustable gastric banding and gastric bypass procedures performed from 2004 to 2007. Quartile trends in the use of all procedures were determined, and a comparison of in-hospital morbidity and mortality between laparoscopic adjustable gastric banding and laparoscopic gastric bypass was performed. RESULTS: A total of 31,333 bariatric surgery procedures were performed from 2004 to 2007. During this period, the use of laparoscopic adjustable gastric banding and gastric bypass procedures increased from 7% to 23% and 53% to 66%, respectively. A concurrent decrease occurred in the use of open gastric bypass procedures from 40% to 11%. Compared with laparoscopic gastric bypass, laparoscopic adjustable gastric banding was associated with a significantly shorter length of stay (1.3 versus 2.7 d, P<.01), lower morbidity (2.8% versus 7.5%, P<.01), lower 30-day readmission rate (.7% versus 2.5%, P<.01), lower in-hospital mortality (.02% versus .08%, P<.01), and lower hospital cost ($8689 versus 14,386, P<.01). CONCLUSION: From 2004 to 2007, significant growth occurred in the number of laparoscopic adjustable gastric banding (+329%) and laparoscopic gastric bypass (+125%) procedures, with a precipitous decrease in the number of open gastric bypass (-73%) procedures. The increasing popularity of the laparoscopic adjustable gastric band procedure could in part be related to the lower cost and lower morbidity compared with laparoscopic gastric bypass.

RESUMO

In patients undergoing bariatric surgery, the presence of metabolic syndrome (MetS) contributes to perioperative morbidity. We aimed to evaluate the utilization and outcome of severely obese patients with MetS who underwent laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB). Using the 2015 and 2016 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, data were obtained for patients with MetS undergoing LSG or LRYGB. There were 29,588 MetS patients (LSG: 58.7% vs LRYGB: 41.3%). There was no significant difference in 30-day mortality (0.1% for LSG vs 0.2% for LRYGB, adjusted odds ratio (AOR) 0.58, confidence interval (CI) 0.32-1.05, P = 0.07) or length of stay between groups (2 ± 2 for LSG vs 2.2 ± 2 days for LRYGB, P = 0.40). Compared with LRYGB, LSG was associated with significantly shorter operative time (78 ± 39 vs 122 ± 54 minutes, P < 0.01), lower overall morbidity (2.3% vs 4.4%, AOR 0.53, CI 0.46-0.60, P < 0.01), lower serious morbidity (1.5% vs 2.3%, AOR 0.64, CI 0.53-0.76, P < 0.01), lower 30-day reoperation (1.2% vs 2.3%, AOR 0.52, CI 0.43-0.63, P < 0.01), and lower 30-day readmission (4.2% vs 6.6%, AOR 0.62, CI 0.55-0.69, P < 0.01). In conclusion, LSG is the predominant operation being performed for severely obese patients with MetS, and its popularity may in part be related to its improved perioperative safety profile.

RESUMO

Importance: The US News & World Report (USNWR) annual ranking of the best hospitals for gastroenterology and gastrointestinal operations provides guidance and referral of care for medical and surgical gastrointestinal conditions. Objective: To investigate whether USNWR top-ranked hospitals for gastroenterology and gastrointestinal surgical procedures are associated with improvements in patient outcomes, compared with nonranked hospitals, in common advanced laparoscopic abdominal operations. Design, Setting, and Participants: This study used the Vizient database, which contains administrative, clinical, and financial inpatient information of index hospitalizations for US academic centers and their affiliated hospitals that are members of Vizient. Data were obtained on advanced laparoscopic abdominal operations performed from January 1, 2017, through December 31, 2017, at USNWR top-ranked hospitals (n = 16 296 operations) and nonranked hospitals (n = 35 573 operations). Abdominal operations included bariatric, colorectal, and hiatal hernia procedures. Operations on patients younger than 18 years, emergent cases, conversion cases, and patients with extreme severity of illness were excluded. Main Outcomes and Measures: Outcome measures included in-hospital mortality, mortality index (observed to expected mortality ratio), serious morbidity, length of stay, and cost. Results: A total of 51 869 advanced laparoscopic abdominal operations were performed at 351 academic health centers and their community affiliates. Of these procedures, 16 296 (31.4%) were performed at 41 top-ranked hospitals and 35 573 (68.6%) at 310 nonranked hospitals. The annual case volume at top-ranked hospitals was 397 compared with 114 at nonranked hospitals. Between top-ranked and nonranked hospitals, no significant differences were found in in-hospital mortality (0.04% vs 0.07%; P = .33) or serious morbidity (1.06% vs 1.02%; P = .75). Compared with nonranked hospitals, advanced laparoscopic abdominal operations performed at top-ranked hospitals had higher mean costs ($7128 [$4917] vs $7742 [$6787]; P < .01) and longer mean lengths of stay (2.38 [2.60] days vs 2.73 [3.31] days; P < .01). Conclusions and Relevance: Although, among academic centers, the annual volume of advanced laparoscopic abdominal operations was 3-fold higher for USNWR top-ranked hospitals compared with nonranked hospitals, the volume did not appear to be associated with improved patient outcomes.

RESUMO

BACKGROUND: Past research suggests self-harm/suicidality are more common among adults who have undergone bariatric surgery than the general population. OBJECTIVES: To compare prevalence of self-harm/suicidal ideation over time and identify presurgery risk factors for postsurgery self-harm/suicidal ideation. SETTING: The Longitudinal Assessment of Bariatric Surgery-2 is a cohort study with presurgery and annual postsurgery assessments conducted at 10 U.S. hospitals. METHODS: Adults with severe obesity undergoing bariatric surgery between March 2006 and April 2009 (n = 2458). Five-year follow-up is reported. Self-reported history of suicidality assessed retrospectively via the Suicide Behavior Questionnaire-Revised (SBQ-R) and self-reported self-harm/suicidal ideation assessed prospectively via the Beck Depression Inventory-Version 1 (BDI-1). RESULTS: The SBQ-R was completed by 1540 participants; 2217 completed the BDI-1 pre- and postsurgery. Over 75% of participants were female, with a median age of 46 years and body mass index of 45.9 kg/m2. Approximately one fourth of participants (395/1534) reported a presurgery history of suicidal thoughts or behavior (SBQ-R). The prevalence of self-harm/suicidal ideation (BDI-1) was 5.3% (95% confidence interval [CI], 3.7-6.8) presurgery and 3.8% (95% CI, 2.5-5.1) at year 1 postsurgery (P = .06). Prevalence increased over time postsurgery to 6.6% (95% CI, 4.6-8.6) at year 5 (P = .001) but was not significantly different than presurgery (P = .12). CONCLUSIONS: A large cohort of adults with severe obesity who underwent bariatric surgery had a prevalence of self-harm/suicidal ideation that may have decreased in the first postoperative year but increased over time to presurgery levels, suggesting screening for self-harm/suicidality is warranted throughout long-term postoperative care. Several risk factors were identified that may help with enhanced monitoring.

RESUMO

OBJECTIVES: To review the outcomes of 104 consecutive minimally invasive esophagectomy (MIE) procedures for the treatment of benign and malignant esophageal disease. SUMMARY BACKGROUND DATA: Although minimally invasive surgical approaches to esophagectomy have been reported since 1992, MIE is still considered investigational at most institutions. METHODS: This prospective study evaluates 104 MIE procedures performed between August 1998 and September 2007. Main outcome measures include operative techniques, operative times, blood loss, length of stay, conversion rates, morbidities, and mortalities. RESULTS: Indications for surgery were esophageal cancer (n = 80), Barrett esophagus with high-grade dysplasia (n = 6), recalcitrant stricture (n = 8), gastrointestinal stromal tumor (n = 3), and gastric cardia cancer (n = 7). Surgical approaches included thoracoscopic/laparoscopic esophagectomy with a cervical anastomosis (n = 47), minimally invasive Ivor Lewis esophagectomy (n = 51), laparoscopic hand-assisted blunt transhiatal esophagectomy (n = 5), and laparoscopic proximal gastrectomy (n = 1). There were 77 males. The mean age was 65 years. Three patients (2.9%) required conversion to a laparotomy. The median ICU and hospital stays were 2 and 8 days, respectively. Major complications occurred in 12.5% of patients and minor complications in 15.4% of patients. The incidence of leak was 9.6% and of anastomotic stricture was 26%. The 30-day mortality was 1.9% with an in-hospital mortality of 2.9%. The mean number of lymph nodes retrieved was 13.8. CONCLUSIONS: Minimally invasive esophagectomy is feasible with a low conversion rate, acceptable morbidity, and low mortality. Our preferred operative approach is the laparoscopic\thoracoscopic Ivor Lewis resection, which provides a tension-free intrathoracic anastomosis.
