Background and Objectives: The use of laparoscopy in the trauma setting is gaining momentum, with more therapeutic procedures being performed. We evaluated the use of laparoscopic splenectomy among trauma patients with data from the National Trauma Database. We compared outcomes for trauma patients undergoing laparoscopic (LS) versus open splenectomy (OS)., Methods: From the National Trauma Database (2007 to 2015), we identified all patients who underwent a total splenectomy. Patients who had other abdominal operations were excluded. All patients were categorized into 1 of 2 groups: LS or OS. Outcomes of in-hospital mortality, postoperative length of stay, and incidence of major complications between the 2 groups were compared. Bivariate parametric and nonparametric analyses were performed. Patients were then matched on baseline demographic and injury characteristics by using propensity score matching techniques, and we compared differences by using regression analysis., Results: A total of 25,408 patients underwent OS and 113 patients underwent LS (0.44%). Patients were significantly different at baseline, with the LS group being less severely injured. Bivariate analysis revealed no difference in length of stay (9 vs 8 days, P = .62), incidence of major complications (10% vs 15%, P = .24), or mortality (6% vs 11%, P = .23). LS was performed in 29.2% of patients beyond 24 hours from presentation compared with 9.5% in the OS ( P < .001). Adjusted multivariate analysis showed no overall difference in outcomes., Conclusion: LS for trauma is increasingly being used at many centers throughout the United States. The procedure is safe, with outcomes similar to those of OS in selected trauma patients., Competing Interests: Conflicts of Interest: All authors declare no conflict of interest regarding the publication of this article.

The management of adhesive small bowel obstruction (ASBO) has evolved from "the sun should not rise and set on a small bowel obstruction", implying mandatory immediate surgical exploration to selective non-operative management. Not every patient with adhesive small bowel obstruction meets criteria for non-operative management and treating all comers the same way can lead to catastrophic outcomes. Water Soluble Contrast Medium (WSCM) has important diagnostic and therapeutic utility in the management of ASBO and should be employed ab initio. Laparoscopy has emerged as a reasonable and safe alternative to laparotomy for surgical management of ASBO in carefully selected patients and has distinct advantages., (Copyright © 2018 Elsevier Inc.

Background: The use of laparoscopy in trauma is, in general, limited for diagnostic purposes. We aim to evaluate the therapeutic role of laparoscopic surgery in trauma patients., Methods: We analyzed the National Trauma Data Bank (2007 to 2010) for all patients undergoing diagnostic laparoscopy. Patients undergoing a therapeutic laparoscopic surgical procedure were identified and tabulated. Mortality and hospital length of stay for patients with isolated abdominal injuries were compared between the open and laparoscopic groups., Results: Of a total of 2,539,818 trauma visits in the National Trauma Data Bank, 4,755 patients underwent a diagnostic laparoscopy at 467 trauma centers. Of these, 916 (19.3%) patients underwent a therapeutic laparoscopic intervention. Common laparoscopic operations included diaphragm repair, bowel repair or resection, and splenectomy. Patients undergoing laparoscopic surgery had a significantly shorter length of stay than the open group (5 vs 6 days; P < .001)., Conclusion: Therapeutic laparoscopic surgery for trauma is feasible and may provide better outcomes., (Copyright © 2015 Elsevier Inc.

Background and Objectives: Ureteral injury is an infrequent but potentially lethal complication of colectomy. We aimed to determine the incidence of intraoperative ureteral injury after laparoscopic and open colectomy and to determine the independent morbidity and mortality rates associated with ureteral injury., Methods: We analyzed data from the National Surgical Quality Improvement Program for the years 2005-2010. All patients undergoing colectomy for benign, neoplastic, or inflammatory conditions were selected. Patients undergoing laparoscopic colectomy versus open colectomy were matched on disease severity and clinical and demographic characteristics. Multivariate logistic regression analyses and coarsened exact matching were used to determine the independent difference in the incidence of ureteral injury between the 2 groups. Multivariate models were also used to determine the independent association between postoperative complications associated with ureteral injury., Results: Of a total of 94,526 colectomies, 33,092 (35%) were completed laparoscopically. Ureteral injury occurred in a total of 585 patients (0.6%). The crude incidence in the open group was higher than that in the laparoscopic group (0.66% versus 0.53%, P=.016). CEM produced 14 630 matching pairs. Matched analysis showed the likelihood of ureteral injury after laparoscopic colectomy to be 30% less than after open colectomy (odds ratio, 0.70; 95% confidence interval, 0.51-0.96). Patients with ureteral injury were independently more likely to have septic complications and have longer lengths of hospital stay than those without ureteral injury., Conclusion: Laparoscopic colectomy is associated with a lower incidence of intraoperative ureteral injury when compared with open procedures. Ureteral injury leads to significant postoperative morbidity even if identified and repaired during the colectomy.

Background: Esophageal diverticulum is rare in the United States. The mainstay treatment of symptomatic esophageal diverticulum is surgical correction. Much of the available information regarding esophageal diverticulum and its surgical management has been derived from small studies and institutional reviews. Our study objective was to investigate the demographics, perioperative conditions, and predictors of outcomes after surgical treatment of acquired esophageal diverticulum using a nationally representative database., Methods: A retrospective review using the Nationwide Inpatient Sample database from 2000-2009 was performed for patients with acquired esophageal diverticulum. The patients were stratified into Zenker's diverticulum (ZD) or non-Zenker's diverticulum (NZD) subgroups. The covariates retrieved included age, gender, ethnicity, insurance type, and Charlson comorbidity index. A multivariate analysis was performed to determine the predictors of postoperative morbidity. Discharge-level weights were applied., Results: Overall, a total of 4253 patients met our inclusion criteria, 3197 (75%) with ZD and 1056 (25%) with NZD. In the ZD group, the mean age was 73 ± 12.3 y, and most were men (55%) and white (67%). The mean length of stay was 5.82 ± 8.08 d, and the mortality rate was 1.2%. The most common complication was septicemia or sepsis (2.0%). The black patients had higher odds of postoperative morbidity than the white patients (odds ratio [OR] 2.29, 95% confidence interval [CI] 1.02-5.17). The risk of overall postoperative morbidity was 52% greater for women (OR 1.52, 95% CI 1.01-2.29). An increasing Charlson comorbidity index was an independent predictor of morbidity. In the NZD group, the mean age was 69 ± 13.9 y, and most were also men (51%) and white (63%). The mean length of stay was 8.13 ± 10.56 d, and the mortality rate was 1.6%. The most common complication was air leak (3.1%). The black and Hispanic patients had higher odds of postoperative morbidity than the white patients (OR 1.97, 95% CI 1.05-3.72 and OR 2.37, 95% CI 1.06-5.30, respectively). An increasing Charlson comorbidity index was an independent predictor of morbidity. Compared with laparoscopy, the risk of developing postoperative morbidity was higher with the thoracotomy procedure (OR 7.45, 95% CI 1.11-50.18)., Conclusions: Using a nationally representative database, our study found that female gender, black race, and the presence of comorbidities were associated with increased postoperative morbidity among patients with ZD. Among the patients with NZD, black and Hispanic patients had worse postoperative morbidity than the white patients, and the presence of comorbidities was associated with increased postoperative morbidity. Thoracotomy for the correction of NZD was associated with increased postoperative morbidity compared with the laparoscopic approach., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Background: Laparoscopy has become a commonly used method of performing colectomies, but the outcomes associated with laparoscopy in the emergency setting have not been well studied., Study Design: The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for patients with diverticulitis without hemorrhage who underwent a colectomy. Patient data retrieved included demographics and preoperative comorbidities. Each member of the cohort received either a primary anastomosis (PA) or a colostomy. Open and laparoscopic procedures were compared within these subgroups. Multivariate logistic regression analyses were performed to compare the risk-adjusted odds of postoperative morbidity and mortality for laparoscopic and open procedures. The risk-adjusted impact of preoperative comorbidities was also assessed., Results: A total of 11,981 patients in the database met the study criteria. The majority were female (53%) and Caucasian (82%), and the mean age was 58 (±13) years. Comorbidities of the cardiovascular, pulmonary, or renal systems were present in 47%, 5%, and 1% of the cohort, respectively. On bivariate analysis, patients undergoing laparoscopy experienced lower rates of complications with both PA (14% vs 26%, p < 0.001) and colostomy (30% vs 37%, p = 0.02). The laparoscopic approach was associated with decreased mortality rates for patients undergoing PA (0.24% vs 0.79%, p < 0.001). Multivariate analysis revealed that preoperative cardiovascular and pulmonary comorbidities were each associated with increased postoperative morbidity, and that the laparoscopic approach was associated with lower postoperative morbidity for patients undergoing PA. The reduced risk of death for patients undergoing laparoscopic PA (vs open approach) did not achieve statistical significance (odds ratio 0.68, p = 0.3). A small number of patients underwent laparoscopic colostomy (n = 237, 2.4%), and they did not have a significantly different risk of death., Conclusions: The laparoscopic approach is associated with lower complication rates compared with the open approach for the surgical treatment of diverticulitis with a primary anastomosis., (Copyright © 2013 American College of Surgeons.

Background: The literature reports the efficacy of the laparoscopic approach to paraesophageal hiatal hernia repair. However, its adoption as the preferred surgical approach and the risks associated with paraesophageal hiatal hernia repair have not been reviewed in a large database., Method: The Nationwide Inpatient Sample dataset was queried from 1998 to 2005 for patients who underwent repair of a complicated (the entire stomach moves into the chest cavity) versus uncomplicated (only the upper part of the stomach protrudes into the chest) paraesophageal hiatal hernia via the laparoscopic, open abdominal, or open thoracic approach. A multivariate analysis was performed controlling for demographics and comorbidities while looking for independent risk factors for mortality., Results: In total, 23,514 patients met the inclusion criteria. By surgical approach, 55% of patients underwent open abdominal, 35% laparoscopic, and 10% open thoracic repairs. Length of stay was significantly reduced for all patients after laparoscopic repair (P < .001). Age ≥60 years and nonwhite ethnicity were associated with significantly higher odds of death. Laparoscopic repair and obesity were associated with lower odds of death in the uncomplicated group., Conclusion: Laparoscopic repair of paraesophageal hiatal hernia is associated with a lower mortality in the uncomplicated group. However, older age and Hispanic ethnicity increased the odds of death.

Introduction: Laparoscopic adjustable gastric banding (LAGB) is a reversible method of surgical gastric restriction. Following LAGB, the adverse event most commonly necessitating subsequent reoperation is prolapse of the gastric corpus or fundus above the band. A review of the medical literature reveals no reports of nonpancreatic pseudocysts being associated with this adverse event. Nonpancreatic pseudocysts, encountered during revisional bariatric surgery should be considered a cause of irreducible gastric prolapse., Case Report: We report the case of a 41-year-old Caucasian female who underwent laparoscopic surgery to revise an adjustable gastric band and to repair an anterior gastric prolapse. Intraoperatively, 2 pseudocysts were found on the gastric fundus above the band in association with the gastric prolapse. The pseudocysts were resected, the gastric prolapse was reduced, and the band was left in place. The patient recovered uneventfully., Conclusion: Nonpancreatic pseudocysts may be associated with gastric prolapse in patients who have undergone LAGB. These pseudocysts can often be excised laparoscopically without violating the gastric lumen. This atypical presentation of gastric prolapse may pose a diagnostic and therapeutic challenge as these patients may.

Background: Laparoscopic appendectomy (LA) has gained acceptance in the treatment of uncomplicated appendicitis in the pediatric population. The role of LA versus open appendectomy (OA) in complicated (perforated) appendicitis has remained controversial., Methods: A 10-y review of the Nationwide Inpatient Sample (HCUP-NIS) and 3 y of non-overlapping data from the Kids' Inpatient Database (KID) (2000, 2003, and 2006) was performed on pediatric patients (age <18 y) with complicated appendicitis. Patients were classified based on gender, race, insurance status, and type of appendectomy performed. Multivariate regression was conducted adjusting for age, race, gender, and type of appendectomy, with mortality and length of hospital stay (LOS) as outcomes., Results: An estimated 72,787 patients met the inclusion criteria with a median age of 11 y. The majorities of the patients were male (59.9%), Caucasian (38.1%), and insured (89.7%). Twenty-nine percent underwent LA while 71% had OA. Proportion of LA increased from 9.9% in 1999 to 46.6% in 2007. On multivariate analysis, African-Americans were less likely to undergo LA compared with Caucasians (OR: 0.80, CI = 0.69-0.92, P = 0.002) despite an increased odds of undergoing LA over the last decade from 1998 to 2007 in the entire study population (OR 6.27, 95% CI 4.73-8.30, P = 0.000). Increasing age and gender were also associated with likelihood of receiving LA (OR: 1.08, CI = 1.06-1.10 and OR 1.25, 95% CI 1.18-1.31, P < 0.001)., Conclusions: LA is gradually gaining acceptance over the years as an alternative to OA for complicated appendicitis, However, minority difference still exists in choice of procedure. There is a need to further investigate this disparity as it may be related to access to skilled laparoscopic pediatric surgeons., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Background: Laparoscopic appendectomy (LA) has been an established treatment method for uncomplicated acute appendicitis. Controversy still exits regarding the superiority of either laparoscopic or open technique for the treatment of complicated appendicitis., Objective: To examine for benefits in postoperative morbidity comparing laparoscopic versus open appendectomy for complicated appendicitis., Methods: A retrospective analysis was performed using the American College of Surgeon's National Surgical Quality Improvement Project (ACS-NSQIP) dataset between 2005 and 2007. Inclusion criteria were patients undergoing either open or laparoscopic appendectomy, and had complicated appendicitis. Patients with negative appendectomies and age less than 18 y old were excluded. The primary outcome variable was postoperative complications. Multivariate analysis was performed adjusting for demographics and standard NSQIP comorbidities., Results: We identified 2,790 complicated appendicitis cases treated with laparoscopic or open appendectomy. The majority were male (56.6%), White (70.3%), and 39.1% were younger than 40 y of age. On unadjusted analyses, the mean length of stay was significantly shorter for LA cases (3.97 d) than OA cases (5.13 d) (P < 0.001). On multivariate analysis, superficial surgical site infection was 70% less likely to occur in LA (OR 0.304 P = 0.000), organ space infection was 2-fold more likely to occur in LA (OR 2.19 P = 0.003), and dehiscence was 78% less likely to occur in LA (OR 0.22 P = 0.015)., Conclusion: In cases of complicated appendicitis, laparoscopic appendectomy is superior in terms of superficial and deep wound infections; however, it is associated with an increased incidence of postoperative intra-abdominal abscess., (Copyright © 2010 Elsevier Inc.

Background: Appendectomy and colectomy are commonly performed surgical procedures. Despite evidence demonstrating advantages with the minimally invasive surgical (MIS) approach, open procedures occur with greater prevalence. Therefore, there is still controversy as to whether the MIS approach is safer or more cost effective., Methods: A retrospective analysis was performed using a large commercial payer database. The data included information on 7,532 appendectomies and 2,745 colectomies. Data on the distribution of patient demographic and comorbidity characteristics associated with the MIS and open approaches were reviewed. The corresponding complication rates and expenditures were analyzed. Summary statistics were compared using chi-square tests, and generalized linear models were constructed to estimate expenditures while controlling for patient characteristics., Results: The patients undergoing MIS and open colectomy showed no significant variations in age distribution or marginal age differences for appendectomy. Significantly more patients experienced an infection postoperatively, and procedure-specific complications were more common in the open group for both procedures (P\0.05). The postsurgical hospital stay was longer for the patients treated using the open techniques, differing an average of half a day for appendectomies and significantly more (4 days) for colectomy (P\0.05). Readmission rates differed little between the two approaches. Procedures performed through an MIS approach were associated with lower expenditures than for the open technique, with differences ranging from $700 for appendectomy patients (P\0.05) to $15,200 for colectomy patients (P\0.05)., Conclusions: Minimally invasive appendectomy and colectomy were associated with lower infection rates, fewer complications, shorter hospital stays, and lower expenditures than open surgery.

Background: Anastomotic and staple line leaks (ASL) occur after laparoscopic Roux-en-Y gastric bypass (LRYGB) with a reported incidence as high as 6%. Leaks are the second most common cause of post-LRYGB mortality after pulmonary embolism, and can be associated with significant morbidity. Prevention and early detection may limit both morbidity and mortality., Methods: A retrospective analysis of prospectively collected data was performed on all LRYGBs performed in a community hospital by a single surgeon from August 2001 to December 2005. All operations were performed using a linear-stapled anastomosis with buttressing material, handsewn otomy closures, stay sutures, intraoperative leak testing, and fibrin sealant., Results: 760 patients underwent LRYGB during the study period. Eighty-nine percent (n = 674) were female and 11% (n = 86) were male. Mean body mass index (BMI) was 50 kg/m2 (range 36-83 kg/m2). Mean age was 40 years (range 17-72 years). Two patients developed three gastric pouch staple line leaks (0.4%). There were no mortalities., Conclusion: Operative technique, including appropriate staple sizing, staple line reinforcement, handsewn otomy closures, placement of stay sutures, intraoperative leak testing, and placement of fibrin sealant contributed to a lower than expected incidence of ASL after LRYGB in this series.

A minimally invasive approach can be beneficial in a spleen-preserving distal pancreatectomy. This article reports a 71-year-old woman who presented to her internist with hypertension and persistent hypokalemia. A computed tomography scan to rule out a functional adrenal mass incidentally revealed a 4 cm x 3 cm x 2 cm serous cystadenoma of the distal pancreas and normal adrenal glands. The patient was referred to the general surgery service for resection of the distal pancreatic lesion. A laparoscopic spleen-preserving distal pancreatectomy was performed. The lesion was completely excised, and the pathology revealed serous cystadenoma with focal fibrosis and atrophic acini. The postoperative advantages of this approach were the early return of bowel function, minimal narcotic requirements, and early resumption of normal activities. This case illustrates the advantages of minimally invasive surgery in the performance of a spleen-preserving distal pancreatectomy.

Background: Telemedicine offers significant advantages in bringing consulting support to distant colleagues. There is a shortage of surgeons trained in performing advanced laparoscopic operations., Aim: Our aim was to evaluate the role of telementoring in the training of advanced laparoscopic surgical procedures., Methods: Student surgeons received a uniform training format to enhance their laparoscopic skills and intracorporeal suturing techniques and specific procedural training in laparoscopic colonic resections and Nissen fundoplication. Subsequently, operating rooms were equipped with three cameras. Telestrator (teleguidance device), instant replay (to critique errors), and CD-ROM programs (to provide information of reference) were used as intraoperative educational assistance tools. In phase I, four colonic resections were performed with the mentor in the operating room (group A) and four colonic resections were performed with the mentor on the hospital grounds, but not in the operating room (group B). The voice and video signals were received at the mentor's location, using coaxial cable. In phase II, two Nissen fundoplications were performed with the mentors in the operating room (group C) and two Nissen fundoplications were performed with the mentors positioned five miles away from the operating room (group D), using currently existing land lines at the T-1 level., Results: There were no differences in the performances of the surgeons and outcome of the operations between groups A & B and C & D. It was possible to tackle the intraoperative problems effectively., Conclusions: The telementoring concept is potentially a safe and cost-effective option for advanced training in laparoscopic operations. Further investigation is necessary before routine transcontinental patient applications are attempted.
