RESUMO
BACKGROUND: Minimally invasive surgery has been used for both de novo insertion and salvage of peritoneal dialysis (PD) catheters. Advanced laparoscopic, basic laparoscopic, open, and image-guided techniques have evolved as the most popular techniques. The aim of this guideline was to develop evidence-based guidelines that support surgeons, patients, and other physicians in decisions on minimally invasive peritoneal dialysis access and the salvage of malfunctioning catheters in both adults and children. METHODS: A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons reviewed the literature since the prior guideline was published in 2014 and developed seven key questions in adults and four in children. After a systematic review of the literature, by the panel, evidence-based recommendations were formulated using the Grading of Recommendations Assessment, Development and Evaluation approach. Recommendations for future research were also proposed. RESULTS: After systematic review, data extraction, and evidence to decision meetings, the panel agreed on twelve recommendations for the peri-operative performance of laparoscopic peritoneal dialysis access surgery and management of catheter dysfunction. CONCLUSIONS: In the adult population, conditional recommendations were made in favor of: staged hernia repair followed by PD catheter insertion over simultaneous and traditional start over urgent start of PD when medically possible. Furthermore, the panel suggested advanced laparoscopic insertion techniques rather than basic laparoscopic techniques or open insertion. Conditional recommendations were made for either advanced laparoscopic or image-guided percutaneous insertion and for either nonoperative or operative salvage. A recommendation could not be made regarding concomitant clean-contaminated surgery in adults. In the pediatric population, conditional recommendations were made for either traditional or urgent start of PD, concomitant clean or clean-contaminated surgery and PD catheter placement rather than staged, and advanced laparoscopic placement rather than basic or open insertion.

BACKGROUND: Mesh reinforced cruroplasty during laparoscopic paraesophageal hernia repair remains controversial due to wide variation in surgical technique and mesh composition. This study aims to review outcomes and rates of recurrence following laparoscopic paraesophageal hernia repair (LPEHR) with mesh reinforced cruroplasty utilizing absorbable mesh at a single institution. METHODS: A retrospective review of all patients who underwent LPEHR with mesh was performed. Medical records were reviewed for patient reported, radiographic or endoscopic evidence of recurrence, defined as > 2 cm of vertical intrathoracic stomach. If no studies were available for review, patients were considered to have no recurrence. Outcomes and mesh-related complications were also reviewed. RESULTS: Between 10/2008 and 9/2021, 473 patients underwent LPEHR with absorbable mesh; 1.3% type 2 hernias, 86.0% type 3 hernias, 12.7% type 4 hernias. Three types of mesh were used: initially biologic mesh (n = 83), then heavyweight synthetic bioabsorbable mesh (n = 261), and finally lightweight synthetic bioabsorbable mesh (n = 111). There were no significant differences in age, ASA, BMI, gender, smoking status, chronic steroid use, preoperative acid suppression, hernia type, or recurrent hernia between groups. There were no significant differences in 30-day postoperative outcomes. Reflux Symptom Index, GERD-HRQL, and Dysphagia Scores at 1- and 2-year postoperative timepoints were not significantly different. The overall recurrence rate was 16.7%, with no significant differences in recurrence rates between biologic, heavyweight or lightweight biosynthetic absorbable mesh through 2 years after surgery. A shorter median time to recurrence (10 months, p = 0.016) was seen in the lightweight group. CONCLUSION: LPEHR with absorbable mesh reinforced cruroplasty is feasible and safe, with equivalent patient-reported outcomes, including dysphagia, up to 2-years postop regardless of mesh choice. No significant differences in recurrence rates between biologic, heavyweight, or lightweight synthetic bioabsorbable mesh were seen up to 2 years after LPEHR.

BACKGROUND: There is substantial media and patient interest in the safety of mesh for hernia repair. However, there is a lack of data regarding health-related quality of life (HRQOL) outcomes in patients who undergo inguinal hernia repair (IHR) with mesh. The purpose of this study is report short and long-term postoperative quality of life outcomes in patients following IHR with mesh. METHODS: We analyzed outcomes of 1720 patients who underwent IHR with mesh between 2008 and 2019 at a single institution from a prospectively maintained quality database. All surgeries were performed by four board-certified surgeons. HRQOL outcomes were measured using the Surgical Outcomes Measurement System (SOMS) and Carolinas Comfort Scale (CCS) surveys that were administered preoperatively, 3 weeks, 6 months, 1, 2, and 5 years postoperatively. Survey responses were summarized as mean with standard deviation or frequency with percentage. Postoperative SOMS scores were compared to preoperative scores using the two-tailed paired t test with a significance level of p < 0.05. RESULTS: One (0.1%) patient experienced a mesh infection postoperatively. In terms of complications, 159 (9.2%) developed a seroma, 31 (1.8%) a hematoma, and 36 (2.1%) patients experienced a recurrence. SOMS Pain Impact, SOMS Pain Quality, and SOMS Pain visual analog scale at 3 weeks, 6 months, 1 year, 2 years, and 5 years were all improved from preoperative (all p < 0.05). At 5 years postoperatively, only 3.9%, 3.2%, and 3.1% of patients reported severe or disabling sensation of mesh, pain, and movement limitations, respectively. CONCLUSION: Inguinal hernia repair with mesh results in a low rate of complications. A minority of patients had severe or disabling symptoms at 5-year follow-up and generally reported improvements in pain impact and quality in long-term follow-up.

INTRODUCTION: The esophagogastric junction (EGJ) is a complex anti-reflux barrier whose integrity relies on both the intrinsic lower esophageal sphincter (LES) and extrinsic crural diaphragm. During hiatal hernia repair, it is unclear whether the crural closure or the fundoplication is more important to restore the anti-reflux barrier. The objective of this study is to analyze changes in LES minimum diameter (Dmin) and distensibility index (DI) using the endoluminal functional lumen imaging probe (FLIP) during hiatal hernia repair. METHODS: Following implementation of a standardized operative FLIP protocol, all data were collected prospectively and entered into a quality database. This data were reviewed retrospectively for all patients undergoing hiatal hernia repair. FLIP measurements were collected prior to hernia dissection, after hernia reduction, after cruroplasty, and after fundoplication. Additionally, subjective assessment of the tightness of crural closure was rated by the primary surgeon on a scale of 1 to 5, 1 being the loosest and 5 being the tightest. RESULTS: Between August 2018 and February 2020, 97 hiatal hernia repairs were performed by a single surgeon. FLIP measurements collected using a 40-mL volume fill without pneumoperitoneum demonstrated a significant decrease in LES Dmin (13.84 ± 2.59 to 10.27 ± 2.09) and DI (6.81 ± 3.03 to 2.85 ± 1.23 mm2/mmHg) after crural closure (both p < 0.0001). Following fundoplication, there was a small, but also statistically significant, increase in both Dmin and DI (both p < 0.0001). Additionally, subjective assessment of crural tightness after cruroplasty correlated well with DI (r = - 0.466, p < 0.001) and all patients with a crural tightness rating ≥ 4.5 (N = 13) had a DI < 2.0 mm2/mmHg. CONCLUSION: Cruroplasty results in a significant decrease in LES distensibility and may be more important than fundoplication in restoring EGJ competency. Additionally, subjective estimation of crural tightness correlates well with objective FLIP evaluation, suggesting surgeon assessment of cruroplasty is reliable.

BACKGROUND: Simulation using virtual reality (VR) simulators is an important tool in surgical training. VR laparoscopic simulators can provide immediate objective performance assessment without observer evaluation. This study aims to explore the correlation between subjective observer evaluation and VR laparoscopic simulator performance metrics in a laparoscopic cholecystectomy (LC) simulation module. METHODS: A LC simulation module using a VR laparoscopic simulator was completed by PGY2-3 general surgery residents at a single institution. Simulation performance was recorded and evaluated by a trained evaluator using the validated Global Operative Assessment of Laparoscopic Skills (GOALS) form, the Objective Structured Assessment of Technical Skills (OSATS) form, and a LC-specific simulation assessment form (LC-SIM). Objective performance metrics were also obtained from the simulator system. Performance before the curriculum (pre-test) and after the curriculum (post-test) were compared. RESULTS: Fourteen residents were included in the study. There were significant improvements from pre-test to post-test on each component of GOALS, OSATS, and LC-SIM scores (all p values < 0.05). In terms of objective simulator metrics, significant improvements were noted in time to extract gallbladder (481 ± 221 vs 909 ± 366 min, p = 0.019), total number of movements (475 ± 264 vs 839 ± 324 min, p = 0.012), and total path length (955 ± 475 vs 1775 ± 632 cm, p = 0.012) from pre-test to post-test. While number of movements and total path lengths of both hands decreased, speed of right instrument also decreased from 4.1 + 2.7 to 3.0 ± 0.7 cm/sec (p = 0.007). Average speed of left instrument was associated with respect for tissue (r = 0.60, p < 0.05) and depth perception (r = 0.68, p < 0.05) on post-test evaluations. CONCLUSION: Our study demonstrated significant improvement in technical skills based on subjective evaluator assessment as well as objective simulator metrics after simulation. The few correlations identified between the subjective evaluator and the objective simulator assessments suggest the two evaluation modalities were measuring different aspects of the technical skills and should both be considered in the evaluation process.

BACKGROUND: Flexible endoscopy is a valuable tool for the gastrointestinal (GI) surgeon, creating a need for effective and efficient training curricula in therapeutic endoscopic techniques for trainees and practicing providers. Here, we present a simulation-based modular curriculum using an "into the fire" approach with hands-on pre- and post-testing to teach endoscopic stenting to practicing surgeons. METHODS: Three advanced flexible endoscopy courses were taught by expert surgical endoscopists from 2018 to 2019. The stenting module involved using self-expandable metal stents to manage simulated esophageal and gastroduodenal strictures on a non-tissue GI model. Based on the educational theories of inquiry-based learning, the simulation curriculum was designed with a series of pre-tests, didactics, mentored hands-on instructions, and post-tests. Assessments included a confidence survey, knowledge-based written test, and evaluation form specific to the hands-on performance of endoscopic stenting. RESULTS: Twenty-eight practicing surgeons with varying endoscopic experiences participated in the course. Most of the participants (67.9%) had completed over 100 upper endoscopic procedures and 57.1% were certified in Fundamentals of Endoscopic Surgery. After completing the modular curriculum, participant confidence survey scores improved from 11.4 ± 4.2 to 20.7 ± 4.0 (p < 0.001). Knowledge-based written test scores also improved from 7.1 ± 1.2 to 8.4 ± 0.9 (p < 0.001). In terms of technical performance, overall hands-on performance scores improved from 21.3 ± 2.7 to 28.9 ± 1.2 (p < 0.001) with significant improvement in each individual component of the assessment (all p values < 0.01) and the greatest improvement seen in equipment handling (88%) and flow of procedure (54%). CONCLUSION: Our modular simulation curriculum using an "into the fire" approach to teach endoscopic stenting is effective in improving learner knowledge, confidence, and hands-on performance of endoscopic stenting. This approach to simulation is effective, efficient, and adaptable to teaching practicing surgeons with varying levels of experience.

INTRODUCTION: This study aims to assess the effect of bariatric surgery on patient-reported outcomes of bowel and bladder function. We hypothesized that bariatric surgery does not worsen bowel and bladder function. METHODS AND PROCEDURES: A retrospective review was conducted of a prospectively maintained surgical quality database. We included patients who underwent primary bariatric surgery at a single institution between 2012 and 2020, excluding revisional procedures. Patient-reported outcomes were assessed using Surgical Outcomes Measurement System (SOMS) bowel and bladder function questionnaires at time of pre-operative consult and routine post-operative follow-up visits through 2 years. Data were analyzed using a statistical mixed effects model. RESULTS: 573 patients (80.6% female) were identified with completed SOMS questionnaire data on bowel and bladder function. Of these, 370 (64.6%) underwent gastric bypass, 190 (33.2%) underwent sleeve gastrectomy, and 13 (2.3%) underwent either gastric banding or duodenal switch. Compared to pre-operative baseline scores, patients reported a transient worsening of bowel function at 2-weeks post-op (p = 0.009). However, by 3-months post-op, bowel function improved and was significantly better than baseline (p = 0.006); this improvement was sustained at every point through 2-year follow-up (p = 0.026). Bladder function scores improved immediately at 2-weeks post-op (p = 0.026) and showed sustained improvement through 1-year follow-up. On subgroup analysis, sleeve patients showed greater improvement in bowel function than bypass patients at 1-year (p = 0.031). Multivariable analysis showed significant improvement in bowel function associated with greater total body weight loss (TBWL) (p = 0.002). CONCLUSIONS: Bariatric surgery does not worsen patient-reported bowel or bladder function. In fact, there is overall improvement from pre-operative scores for both bowel and bladder function by 3-months post-op which is sustained through 2-year and 1-year follow-up, respectively. Most encouragingly, a greater TBWL is significantly associated with improved bowel function after bariatric surgery.

Background. There are growing interests from practicing endoscopists to implement the functional lumen imaging probe (FLIP) impedance planimetry system. We present a simulation-based curriculum using an "into the fire" approach with hands-on pre- and post-tests to teach the use of this technology. Methods. The curriculum consists of a series of pre-tests, didactic content, mentored hands-on instructions, and post-tests. Pre- and post-testing included a knowledge-based written test, a confidence survey, and an assessment form specific to the hands-on performance of FLIP. Result. Twenty-two practicing physicians completed the curriculum. After course completion, participants had improved knowledge-based written test scores from 6.8±1.7 to 8.9±0.9 (P<0.001), confidence scores from 10.0±5.9 to 22.1±2.6 (P<0.001), and hands-on performance score from 11.4±3.4 to 23.1±2.0 (P<0.001) with significant improvement in all components of the hands-on skills. Conclusion. Our simulation curriculum is effective in improving confidence, knowledge, and technical proficiency when teaching the use of FLIP to practicing physicians.

INTRODUCTION: Peroral endoscopic myotomy (POEM) is a minimally invasive treatment for achalasia. Considerable evidence demonstrates a high incidence of gastroesophageal reflux disease (GERD) after POEM. The endoluminal functional lumen imaging probe (FLIP) uses impedance planimetry to obtain objective measurements of the gastroesophageal junction. This study aims to determine whether FLIP measurements collected at the time of POEM are associated with the development of reflux esophagitis postoperatively. METHODS: Patients who underwent POEM between 2012 and 2019 who subsequently had esophagogastroduodenoscopy (EGD) were included. Intraoperative FLIP measurements before and after myotomy, clinical data from EGD, and reflux specific quality of life questionnaires were collected. Comparisons between groups were made using the Wilcoxon rank-sum and Fisher's exact tests. Receiver operating characteristic (ROC) curves were used to determine optimal cutoffs of measurements to classify patients into those with high risk of postoperative esophagitis and those with lower risk. RESULTS: A total of 43 patients were included. Of those, 25 (58.1%) were found to have esophagitis on postoperative EGD: four patients (16%) with LA Grade A, five (20%) with LA Grade B, 11 (44%) with LA Grade C and two (8%) with LA grade D esophagitis. Patients with a final distensibility index ≥ 2.7 and a final cross-sectional area ≥ 83 were significantly more likely to develop esophagitis on postoperative EGD (p = 0.016 and p = 0.008, respectively). Gastroesophageal reflux disease health-related quality of life (GERD-HRQL) and reflux symptom index (RSI) scores were not significantly different in patients who developed esophagitis and those who did not. CONCLUSION: Reflux affects some patients after POEM. We show that FLIP measurements collected during POEM may help predict which patients are more likely to develop reflux esophagitis postoperatively. Subjective symptoms on quality of life questionnaires are not reliable in determining which patients are at risk for esophagitis.

BACKGROUND: Although peroral endoscopic myotomy (POEM) has emerged as a highly efficacious procedure in the treatment of a variety of esophageal motility disorders, currently no standard pathway for postprocedural care exists. Our study aims to report institutional outcomes in performing POEM as an outpatient procedure with same-day discharge. Additionally, we seek to determine factors associated with admission. METHODS: Demographic, perioperative, and postoperative outcome data of 115 patients who underwent POEM between June 2014 and January 2020 on a same-day discharge pathway were analyzed. Cohorts were compared using the t test, Wilcoxon rank-sum, or chi-square test. Multivariable logistic regression with a manual backward selection method was used to identify factors associated with admission. RESULTS: Fifty-five patients (48%) were successfully discharged same-day. The most common primary reasons for admission were delay in obtaining an esophagram (25%), intraoperative complication (13.3%), and pain (10%). There were no differences in 30-day ED visit rate (12.7% vs 15.0%, p = 0.725) or 30-day readmission rate (9.1% vs 16.7%, p = 0.373) between patients who were discharged same-day versus patients who were admitted. Patients discharged same-day had fewer intraoperative complications (1 vs 9, p = 0.017), shorter OR time (69 vs 100 min, p < 0.001), and earlier cessation of narcotic use (day 0 vs day 1, p = 0.001). On multivariable analysis, intraoperative complication (p = 0.048) was associated with overnight admission. CONCLUSION: Patients did not experience additional morbidity with same-day discharge after POEM. A delay in obtaining an esophagram was the most common reason that patients were admitted and those who suffered an intraoperative complication are more likely to require admission.

BACKGROUND: Outcomes of incisional hernia repair (IHR) include recurrence and quality of life (QOL). Operative approaches include laparoscopic, open, and robotic approaches. Data regarding comparative QOL outcomes among these repair types are unknown. Our study evaluates quality of life after three approaches to IHR. STUDY DESIGN: Patients undergoing open (OHR), laparoscopic (LIHR), and robotic extra-peritoneal (RIHR) at a single institution from 2009 to 2019 were reviewed from a prospectively managed quality database. Short-term QOL was compared among the three procedures using the Surgical Outcomes Measurement System (SOMS) and Carolinas Comfort Scale (CCS), objective pain scores and postoperative narcotic use. Data regarding length of stay (LOS), emergency department (ED) visits, readmission, reoperations and surgical site infection (SSI) were also collected. RESULTS: A total of 795 patients undergoing IHR were analyzed (418 open, 300 laparoscopic and 77 robotic). Patient were similar in age, gender and co-morbidities. LIHR patients had higher BMI and RIHR patients had larger hernia and mesh size. LOS was longer and rate of SSI was higher for OIHR compared to laparoscopic and RIHR. Patients undergoing LIHR reported increased narcotic use, Visual Analogue Scale (VAS) and CCS pain scores compared to open and robotic repair. Return to daily activity was 4 days shorter for robotic than open and laparoscopic repair; ED visits, readmissions, reoperations, and other QOL domains were similar. CONCLUSION: Our data suggests that short-term quality of life after robotic extra-peritoneal IHR is improved compared to open and laparoscopic repair. Additional follow up is required to determine differences in long-term QOL after IHR.

BACKGROUND: Anti-reflux mucosectomy (ARMS) is a new endoscopic procedure involving a hemi-circumferential endoscopic mucosal resection (EMR) around the gastroesophageal junction. We aim to compare perioperative and quality of life outcomes of patients with reflux who underwent ARMS to a comparable group who underwent laparoscopic Nissen fundoplication (NF). METHODS: A retrospective review of a prospectively maintained quality database was performed. All patients who underwent ARMS (n = 33) were matched with patients who underwent NF (n = 67). Clinical and quality of life (QOL) outcomes were collected preoperatively and up to two years postoperatively, measured by the Reflux Symptom Index (RSI), Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL), and Dysphagia Score. Outcomes were compared using the Wilcoxon rank-sum and Fisher's exact test. RESULTS: While 10 patients (30.3%) who underwent ARMS required additional laparoscopic anti-reflux operations, the ARMS group had shorter OR time (p<0.001), less estimated blood loss (p<0.001), shorter hospital stay (p<0.001), less pain at discharge (p = 0.007), earlier narcotic discontinuation (p<0.001), and earlier return to activities of daily living (p<0.001) compared to the NF group. There was no difference in 30-day complication rates, emergency room visits, or readmission rates between the groups. There was no difference between ARMS and NF groups in terms of GERD-HRQL, RSI, or Dysphagia scores at 3 weeks, 6 months, 1 year, or 2 years postoperatively. However, the ARMS group reported less symptoms of gas and bloating postoperatively at all time points (all p<0.05). Both groups reported increased dysphagia at 3 weeks postoperatively (p<0.01) but this did not persist at 6 months, 1 year, or 2 years. CONCLUSION: While ARMS had better perioperative outcomes compared to NF, reflux quality of life outcomes were comparable. ARMS can be an effective endoscopic intervention for GERD when performed on appropriately selected patients without limiting future laparoscopic anti-reflux interventions.

INTRODUCTION: The Endoluminal Functional Lumen Imaging Probe (Endoflip) can be used to provide objective measurements of the gastroesophageal junction during fundoplication, and recent publications have suggested that this device could improve surgical outcomes. However, the impact of operative variables has not been clearly reported. The aim of this study is to determine the effect of these variables on functional lumen imaging probe (FLIP) measurements. METHODS: Following implementation of a standardized operative FLIP protocol, all data were collected prospectively and entered into a quality database. This database was queried for patients undergoing hiatal hernia repair and fundoplication. The protocol utilized various balloon volumes (30 and 40 ml), patient positions (flat and reverse Trendelenburg) and amounts of insufflation (15 mmHg pneumoperitoneum and no pneumoperitoneum). RESULTS: Between August 2018 and February 2020, 97 fundoplications were performed by a single surgeon. Multivariable analysis without interactions demonstrated that a 40 ml volume fill resulted in significantly higher minimum diameter (Dmin), cross-sectional area (CSA), intra-balloon pressure (IBP) and distensibility index (DI) compared to a 30 ml volume fill (p < 0.001). While reverse Trendelenburg positioning resulted in a significantly higher Dmin, IBP and CSA compared to the flat position (all p < 0.05), there was little impact of positioning on DI. Lastly, pneumoperitoneum significantly increased IBP (p < 0.001) but did not affect Dmin (p = 0.697) or CSA (p = 0.757), which resulted in a significant decrease in DI (p < 0.001) when compared to measurements without pneumoperitoneum. Multivariable analysis allowing for interactions demonstrated significant two-way interactions between balloon volume and pneumoperitoneum (p = 0.047), as well as patient position and pneumoperitoneum (p < 0.001). CONCLUSION: Surgeons should consider balloon volume and the presence or absence of pneumoperitoneum when interpreting distensibility during or after fundoplication. Additionally, we suggest a formal standardized protocol for FLIP measurements to utilize a 40 ml volume fill in reverse Trendelenburg without pneumoperitoneum.

BACKGROUND: Postoperative urinary retention (POUR) is a complication of laparoscopic inguinal hernia repair (LIHR). Previous research has identified predictive factors of POUR, such as age and history of benign prostatic hyperplasia (BPH). There is currently limited work on preventative measures. We hypothesize dexamethasone, a steroid, reduces POUR rates following LIHR due to its mechanism. METHODS: Consecutive patients (n = 979) undergoing LIHR from 2009 to 2017 at a single institution were selected from a prospectively managed database. All procedures were performed by four general surgeons. Only male patients were selected, as the majority of POUR occurs in males. Patients were retroactively chart reviewed and divided into two groups, dexamethasone use (n = 623) and no dexamethasone use (n = 356). Perioperative factors were compared between groups with Chi-square and independent samples t tests. Univariable and multivariable logistic regression analysis was used to assess whether dexamethasone use was associated with POUR. A subgroup analysis was performed on the dexamethasone group to determine any dose-dependent effects. RESULTS: We found a significant difference in POUR between the dexamethasone group and no dexamethasone group (3.7% vs. 9.8%, p = 0.0001). Patients in the dexamethasone group had a shorter length of stay, and were less likely to have BPH or a Foley placed (all p < 0.05). Age and BMI were similar between groups. Multivariable analysis showed that the use of dexamethasone was associated with a reduced risk of POUR (OR 0.52, 95% CI 0.2-0.97, p = 0.0386), while controlling for factors such as age and BPH. A subgroup analysis examined the effect of dexamethasone per unit (mg) increase. There was no significant association between dexamethasone dose and POUR rates (OR 1.07, 95% CI 0.82-1.38, p = 0.6241). CONCLUSIONS: Patients who received dexamethasone showed a lower rate of POUR regardless of dose. These results suggest dexamethasone can be administered to reduce POUR in males undergoing LIHR.

BACKGROUND: It remains unclear whether use of self-fixating mesh during laparoscopic inguinal hernia repair (LIHR) impacts postoperative quality of life (QoL). We hypothesize patients receiving self-fixating mesh during totally extraperitoneal (TEP) LIHR will report less pain and improved QoL compared to those receiving non-fixating mesh. METHODS: An IRB-approved, single-blinded randomized controlled trial was conducted. Patients with primary, unilateral inguinal hernias were randomized to receive either non-fixating (control) or self-fixating mesh. Clinical visits were conducted 3 weeks and 1 year after LIHR. A validated Surgical Outcomes Measurement System (SOMS) instrument was used to assess patients' QoL preoperatively and postoperatively along with Carolinas Comfort Scale (CCS) at 3 weeks and 1 year after surgery. Comparisons between self-fixating and non-fixating mesh groups were made using Chi-square, Wilcoxon rank-sum or independent samples t tests. RESULTS: Two hundred and seventy patients were enrolled (137 non-fixating vs 133 self-fixating). Preoperatively, there was no difference in mean age, BMI, or median hernia duration between groups (57.9 vs 56.6 years, p = 0.550; 26.1 vs 26.8, p = 0.534; 3.0 vs 3.0 months, p = 0.846). Median operative times (34 vs 34 min, p = 0.545) and LOS were similar. More patients in the non-fixating group received tacks (43 vs 19, p = 0.001). Patients receiving non-fixating mesh recorded better mean SOMS scores for the first 3 days following surgery (Day 1: p = 0.005; Day 2: p = 0.002; Day 3: p = 0.024, Table 1) indicating less pain. No differences in pain were seen 3 weeks or 1 year postoperatively. There were zero recurrences found during clinical follow-up in either of the groups. CONCLUSIONS: Patients receiving self-fixating mesh report worse postoperative pain in the first 2-3 days than those receiving non-fixating mesh. The groups showed no differences across QoL metrics (SOMS and CCS) at 3 weeks or 1 year postoperatively. Self-fixating mesh does not appear to positively impact QoL after TEP LIHR.

BACKGROUND: Acute diverticulitis (AD) presents a unique diagnostic and therapeutic challenge for general surgeons. This collaborative project between EAES and SAGES aimed to summarize recent evidence and draw statements of recommendation to guide our members on comprehensive AD management. METHODS: Systematic reviews of the literature were conducted across six AD topics by an international steering group including experts from both societies. Topics encompassed the epidemiology, diagnosis, management of non-complicated and complicated AD as well as emergency and elective operative AD management. Consensus statements and recommendations were generated, and the quality of the evidence and recommendation strength rated with the GRADE system. Modified Delphi methodology was used to reach consensus among experts prior to surveying the EAES and SAGES membership on the recommendations and likelihood to impact their practice. Results were presented at both EAES and SAGES annual meetings with live re-voting carried out for recommendations with < 70% agreement. RESULTS: A total of 51 consensus statements and 41 recommendations across all six topics were agreed upon by the experts and submitted for members' online voting. Based on 1004 complete surveys and over 300 live votes at the SAGES and EAES Diverticulitis Consensus Conference (DCC), consensus was achieved for 97.6% (40/41) of recommendations with 92% (38/41) agreement on the likelihood that these recommendations would change practice if not already applied. Areas of persistent disagreement included the selective use of imaging to guide AD diagnosis, recommendations against antibiotics in non-complicated AD, and routine colonic evaluation after resolution of non-complicated diverticulitis. CONCLUSION: This joint EAES and SAGES consensus conference updates clinicians on the current evidence and provides a set of recommendations that can guide clinical AD management practice.

BACKGROUND: Obesity has been considered a relative contraindication to peritoneal dialysis (PD). Surprisingly, PD catheter dysfunction rates and longevity have not been studied in the growing obese ESRD population. The aim of this study was to determine the effect of patient weight on PD catheter survival in the three insertion technique categories of advanced laparoscopy (AL), basic laparoscopy (BL), and open. METHODS: We examine retrospectively collected data on 231 consecutive PD catheter insertions at the NorthShore University HealthSystem between 2004 and 2014. Three cohorts were created based on the catheter insertion technique: open, BL using selective adhesiolysis, and AL using rectus sheath tunnel, selective omentopexy, and adhesiolysis. Primary outcomes included catheter dysfunction and catheter dysfunction-free survival for each cohort by BMI: normal weight (18.5-24.9), overweight (25-29.9), obese (≥30). Nominal variables were compared using Chi-square test, continuous variables using ANOVA or Kruskal-Wallis tests, and catheter survival was assessed using the Kaplan-Meier method with log-rank test. Statistical significance was established at 0.05. RESULTS: For the three BMI categories, there were no statistically significant differences in patient demographics. There were no statistically significant differences in catheter dysfunction or peri-operative complications by BMI category among all patients. This was also true in the AL cohort. Among all patients, similar 2-year dysfunction-free catheter survival was noted for normal weight, overweight, and obese patients (log-rank p = 0.79). This was also true across all insertion techniques: open (log-rank p = 0.87), BL (log-rank p = 0.41), AL (log-rank p = 0.43). In the obese cohort, the 2-year dysfunction-free catheter survival was 91.1% in AL, 83.5% in BL, and 65.7% in open (log-rank p = 0.58). CONCLUSION: Obesity does not increase complications or shorten dysfunction-free PD catheter survival regardless of the operative technique used. Obesity should not be considered as a relative contraindication to PD catheter placement as it confers similar technique success to normal- and overweight individuals.

INTRODUCTION: Primary obesity surgery, endoluminal (POSE) is a promising procedure for weight loss surgery because it is outpatient, is incisionless and has short recovery time. We demonstrate the POSE procedure as a potential option for the bariatric patient. MATERIALS AND METHODS: Using an endoluminal camera, we videotaped one of our surgeons performing the POSE procedure. With rows of sutures in the fundus and antrum, the stomach's volume is reduced. RESULTS: We demonstrate a successful POSE procedure in its entirety. CONCLUSIONS: The POSE procedure is a promising option for the bariatric patient. Long-term studies are needed to show its efficacy.

BACKGROUND: It is unknown whether acid/reflux control prevents progression in Barrett's esophagus. In this study, we investigate whether medical or surgical control of reflux is associated with a decreased risk of progression to dysplasia/esophageal adenocarcinoma. METHODS: We retrospectively collected and analyzed data from a cohort of Barrett's esophagus patients participating in this single-center study comprised of all patients diagnosed with Barrett's esophagus at NorthShore University Health System hospitals and clinics over a 10-year period. Patients were followed in order to identify those progressing from Barrett's esophagus to low-grade dysplasia, high-grade dysplasia, and esophageal adenocarcinoma. We collected information from the patient's electronic medical records regarding demographic, endoscopic findings, histological findings, smoking/alcohol history, medication use including proton-pump inhibitors, and history of bariatric and antireflux surgery. Risk-adjusted modeling was performed using multivariable logistic regression. RESULTS: This study included 1,830 total Barrett's esophagus patients, 102 of which had their Barrett's esophagus progress to low-grade dysplasia, high-grade dysplasia, or esophageal adenocarcinoma (confirmed by biopsy) with an annual incidence rate of 1.1%. Mean follow-up period was 5.51 years (10,083 patient-years). Compared to the group that did not progress, the group that progressed was older (69.3 ± 13.7 vs. 63.9 ± 13.4 years. p < 0.001) and likely to be male (75 vs. 61%, p < 0.01). In the multivariable analysis, patients who had a history of antireflux surgery (n = 44) or proton-pump inhibitor use without surgery (n = 1,641) were found to progress at significantly lower rates than patients who did not have antireflux surgery or were not taking PPI's (OR 0.18, 95% CI 0.09-0.36). CONCLUSIONS: Reflux control was associated with decreased risk of progression to low-grade dysplasia, high-grade dysplasia, or esophageal adenocarcinoma. These results support the use of reflux control strategies such as proton-pump inhibitor therapy or surgery in patients with non-dysplastic Barrett's esophagus for the prevention of progression to dysplasia/adenocarcinoma.

INTRODUCTION: Barrett's esophagus (BE) is the most predictive risk factor for development of esophageal adenocarcinoma (EAC), a malignancy with the fastest increasing incidence in the US. The aim of this study was to investigate differences in exposures, demographics, and comorbidities between regressing and non-regressing patients. METHODS AND PROCEDURES: We retrospectively collected and analyzed data from a cohort of BE patients participating in a single-center study comprised of all patients diagnosed with BE over a 10-year period. We collected information from the patient's electronic medical records regarding demographic data, endoscopic findings, histological findings, exposures, and history of antireflux surgery. RESULTS: This study included 1,342 BE patients, 505 (37.6%) of which experienced regression. The regressed group was 52.3% male, while the non-regressing group was 68.3% male (p < 0.001). Mean age was 65.2 ± 12.8 and 62.0 ± 13.1 years for non-regressing and regressing patients, respectively (p < 0.001). No difference was seen in BMI between regressing and non-regressing groups (27.5 ± 5.7 vs. 27.7 ± 5.4, p = 0.52). No difference was seen between groups with respect to PPI use (93.5% non-regressing vs. 94.1% regressed patients, p = 0.70), but regressed patients were more likely to take vitamin D than non-regressing patients (34.1 vs. 42.1%, p = 0.003). Regressed patients had an average segment length of 1.48 cm (±1.58 cm), in contrast to those not regressing (3.58 ± 3.09 cm (p < 0.001)). Interestingly, one patient in the regression group progressed to dysplasia, while 101 of the non-regressing patients progressed to dysplasia/EAC, a result found to be independent of segment length on multivariate analysis (p < 0.001). CONCLUSIONS: Currently, several studies have shown risk factors that can predict progression of non-dysplastic BE, but few investigate predictors for regression. Our study reports several factors that can be used to predict patients who will regress from BE and those who likely will not, tools that will be useful in tailoring therapeutic and surveillance strategies.
