Robotic Surgery for Pediatric Choledochal Cysts: An American Case Series and Literature Review.

INTRODUCTION: Choledochal cysts are rare congenital biliary cystic dilations. The US incidence rate varies between 5 and 15 cases per 1,000,000 people. In contrast, Asians, which are a large subset of the population of Hawaii, have an incidence of approximately one in every 1000 births. We report our experience with robot-assisted laparoscopic surgical management with biliary reconstruction of choledochal cysts which to date is the largest American case series to be reported. MATERIALS AND METHODS: From 2006 to 2021, patients diagnosed with a choledochal cyst(s) at a tertiary children's hospital were retrospectively reviewed. Perioperative analysis was performed. Complications were defined as immediate, early, or late. The data underwent simple descriptive statistics. RESULTS: Nineteen patients underwent choledochal cystectomy and hepaticoduodenostomy. Thirteen underwent a robotic approach while the rest were planned laparoscopic. Eighteen of 19 were female with 15/19 of Asian descent. The ages ranged from 5 mo to 21 y. Presenting diagnoses included jaundice, primary abdominal pain, pancreatitis, and cholangitis. Sixty eight percent had type 1 fusiform cysts while the rest were type 4a. Operative time and length of stay for robotic versus laparoscopic were 321 versus 267 min and 8.2 versus 17.3 d, respectively. For the robotic group, there was one immediate complication due to peritonitis. One-year follow-up revealed two patients requiring endoscopic retrograde cholangiopancreatography with dilation/stenting for an anastomotic stricture. There were no anastomotic leaks. CONCLUSIONS: Robot-assisted laparoscopic choledochal cystectomy with hepaticoduodenostomy is associated with overall good outcomes with the most common long-term complication being anastomotic stenosis.

Is Laparoscopy Underutilized for Sigmoid Volvulus?

PURPOSE: Minimally invasive surgery has become increasingly prevalent. However, the majority of colectomies for volvulus are still performed via an open technique. The purpose of this study is to determine whether there is a difference in outcomes between laparoscopic and open procedures for sigmoid volvulus. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program and colectomy-targeted procedure databases were queried from 2013 to 2018. Patients undergoing partial colectomy without ileal resection for the indication of volvulus were compared based on approach (planned laparoscopic vs. planned open). The 2 groups were propensity score matched for perioperative variables. A subgroup analysis was performed comparing unplanned laparoscopic conversion to open (CTO) with planned open procedures. The primary outcomes were overall morbidity, mortality, and length of stay. RESULTS: Total 2493 patients were identified. Four hundred ninety-two cases began laparoscopically (20%), of which 391 were completed laparoscopically (79%). Laparoscopic approach was associated with longer operative times (133 vs. 104 min, P <0.001). Laparoscopic approach was associated with decreased overall morbidity (OR: 0.71, 95% CI, 0.54 to 0.93) and decreased length of stay when >7 days (OR: 0.70, 95% CI, 0.52 to 0.94). On subgroup analysis, there was no difference in outcomes when comparing unplanned CTO to planned open approach. CONCLUSIONS: Laparoscopic approach is used in a fraction of cases for colonic volvulus. When utilized, the majority are completed without CTO. Laparoscopy is associated with fewer complications and shorter hospital stays. Even with unplanned conversion to open, there is no difference in outcomes compared against planned open procedures. Surgeons should consider the utilization of laparoscopy for colonic volvulus.

Same day discharge does not lead to worse outcomes in patients undergoing uncomplicated laparoscopic foregut surgery.

INTRODUCTION: With the advancement of minimally invasive surgical techniques surgeons have moved away from elective open foregut surgeries. Despite studies demonstrating the safety of same day discharge in appropriate patient populations, ambulatory surgery has yet to be established as the practice norm for patients undergoing uncomplicated laparoscopic foregut surgery. METHODS: The ACS-NSQIP database was queried from 2005 to 2018 for patients who had undergone elective and non-emergent laparoscopic Heller myotomy, fundoplication, and paraesophageal hernia repairs with and without mesh. The primary endpoints in this study included number and severity of complications as classified by the Clavien-Dindo Classification, readmission, and return to the operating room. RESULTS: 6893 patients who met inclusion criteria were identified, 696 (10.1%) of which were discharged on the day of surgery. Patients who were discharged on post-operative day one were matched at a 3:1 ratio producing 2088 comparisons. There was no difference in overall morbidity (p = 0.264), readmission (OR 0.849, 95% CI 0.522-1.419), or return to the operating room (OR 1.15, 95% CI 0.531-2.761) between the two groups. CONCLUSION: Same day discharge for patients without life threatening comorbidities undergoing elective minimally invasive Heller myotomy, Nissen and Toupet fundoplication, and paraesophageal hernia repairs is safe and feasible.

Role of Negative Pressure Wound Therapy When Performing Elective Open Colectomy.

Background: The impact of negative pressure wound therapy (NPWT) as an adjunct to colorectal surgery is largely unknown. The purpose of this study was to determine whether NPWT impacts wound complications during elective open colectomy. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and colectomy targeted procedure databases were queried from 2012-2018 for patients undergoing non-emergent planned open colectomies. Groups were propensity score matched for anastomosis type (ileo-colic, colo-colic, colo-rectal), age, body mass index (BMI), diabetes, smoking, steroid use, wound classification, American Society of Anesthesiologists (ASA) class, operative time, and wound layers closed. Wound complications were defined as superficial surgical site infection (SSI), deep incisional SSI, and dehiscence. Results: A total of 15,770 patients were identified; 92 underwent simultaneous NPWT (0.58%). Non-NPWT patients were matched at a 5:1 ratio, producing 460 comparisons. There was no difference in wound complications (8.26% non-NPWT vs. 6.52% NPWT; p = 0.574). In addition, there were no differences in wound complications when only including patients who had NPWT placed over closed skin (9.11% non-NPWT vs. 7.25% NPWT; p = 0.789). On multivariable analysis, NPWT was not associated with wound complications (odds ratio [OR] 0.79; 95% confidence interval [CI], 0.37-1.69). Conclusions: Negative pressure wound therapy does not reduce wound complications in open elective colectomies. Large randomized studies and more granular data are needed to ascertain if there is any benefit in select patient populations.

Time to weigh in on obesity and associated comorbidities in combat-wounded amputees.

BACKGROUND: The Joint Trauma System database estimates that about 1,200 individuals have sustained a combat-related amputation during the Global War on Terror. Previous retrospective studies have demonstrated that combat-related amputees develop obesity and cardiovascular disease, but the incidence of obesity and associated comorbidities in this population is unknown. The objectives of this study are to determine the prevalence of obesity in the military amputee population and to compare this with the general population. METHODS: This is a retrospective review of 978 patients who sustained a combat-related amputation from 2003 to 2014. Prevalence of obesity and comorbid conditions were determined. A multivariate logistic regression model was performed to identify risk factors for postamputation obesity. Kaplan-Meier curves were constructed using obesity as the event of interest. RESULTS: A total of 1,233 charts were reviewed with 978 patients included for analysis. The median age of injury was 24 years. Median follow-up time was 8.7 years, ranging from 0.5 years to 16.9 years. The average Injury Severity Score was 23.3. The average body mass index preinjury was 25.6 kg/m2, and the average most recent corrected body mass index was found to be 31.4 kg/m2. Prevalence of comorbidities was higher in the amputee population. Fifty percent of patients who progressed to obesity did so within 1.3 years. CONCLUSION: There is a notable prevalence of obesity that develops in the amputee population that is much higher than the general population. We determined that the amputee population is at risk, and these patients should be closely monitored for 1 to 2.5 years following injury. This study provides a targeted period for which monitoring and intervention can be implemented. LEVEL OF EVIDENCE: Retrospective, basic science, outcomes analysis, level III/IV.

Internet resources for podiatric medical students: a second update.

In this article, we present a selection of Internet resources covering subject areas found in standard medical education curricula. Basic sciences and clinical resource sites are explored. We also review Web sites that offer useful materials that can be downloaded to handheld devices such as palmtop computers, smartphones, and portable media players. We judged the sites based on their potential to enhance the learning process, provide practice questions or study guides for examinations, or aid in the preparation of manuscripts. Medical students, residents, educators, and practitioners of podiatric medicine and surgery who require a quick reference source to either the basic science foundations of podiatric medicine or the clinical side of basic medicine, may find this paper useful.
