    ABSTRACT: Age, superobesity, and cardiopulmonary comorbidities define patients as high risk for bariatric surgery. We evaluated the outcomes following bariatric surgery in extremely high-risk patients. Among 3240 patients who underwent laparoscopic bariatric surgery at a single academic center from January 2006 through June 2012, extremely high-risk patients were identified using the following criteria: age ≥65 years, body mass index (BMI) ≥50 kg/m(2), and presence of at least two of six cardiopulmonary comorbidities, including hypertension, ischemic heart disease, congestive heart failure, chronic obstructive pulmonary disease, obstructive sleep apnea, and history of venous thromboembolism. Perioperative and intermediate-term outcomes were assessed. Forty-four extremely high-risk patients underwent laparoscopic Roux-en-Y gastric bypass (n=23), adjustable gastric banding (n=11), or sleeve gastrectomy (n=10). Patients had a mean age of 67.9±2.7 years, a mean BMI of 54.8±5.5 kg/m(2), and a median of two (range, two to five) cardiopulmonary comorbidities. There was no conversion to laparotomy. Thirteen (29.5%) 30-day postoperative complications occurred; only six were major complications. Thirty-day postoperative re-admission, re-operation, and mortality rates were 15.9%, 2.3%, and 0%, respectively. Within a mean follow-up time of 24.0±18.4 months, late morbidity and mortality rates were 18.2% and 2.3%, respectively. The mean percentage total weight and excess weight losses after at least 1 year of follow-up were 26.7±12.0% and 44.1±20.6%, respectively. Laparoscopic bariatric surgery is safe and can be performed with acceptable perioperative outcomes in extremely high-risk patients. Advanced age, BMI, and severe cardiopulmonary comorbidities should not exclude patients from consideration for bariatric surgery.

    ABSTRACT: The importance of port closure after laparoscopic surgeries is emphasized by the extensive number of techniques being described for the same. Even so, the search for a simple, time-saving, and effective technique still continues. One commonly overlooked factor is the obliquity of laparoscopic ports, which makes direct visualization of the rectus fascia through the skin incision difficult. Also, our patients, mostly of Indian ethnicity, tend to have relatively thick subcutaneous fat that again acts as a constraint during port closure. We have described a simple and effective method of laparoscopic port closure using Moynihan's aneurysm needle and a skin hook. This technique is particularly advantageous in the above-mentioned scenarios. We have been successfully using this technique in our institution for the past 6 years, and we have not encountered any case of port-site hernia. Our technique does not require expensive instruments or the need for visualization via a camera.

    ABSTRACT: As medical and surgical interventions to support premature infants have evolved, the need for long-term vascular access in extremely low birth weight infants has increased. The classic approach to Broviac(®) (C.R. Bard, Covington, GA) catheter placement in very small neonates has been through an open surgical cutdown technique. Ultrasound guidance has emerged as a potentially beneficial method for obtaining central venous access in children and is being applied to smaller and smaller infants. This case series reports the feasibility of using ultrasound-guided percutaneous vein access to obtain a long-term central venous line in three extremely low birth weight infants who all weighed less than 850 g at the time of line placement.

    ABSTRACT: Total proctocolectomy (TPC) and ileal pouch anal anastomosis (IPAA) have become the standard of care for patients with ulcerative colitis refractory to medical management. The purpose of our study is to show our single-site approach and to identify maneuvers that improve efficiency. We retrospectively reviewed patients who underwent single-site three-stage TPC-IPAA for ulcerative colitis at our institution. Primary outcomes included operative time, conversion from single site to standard laparoscopy, time to oral intake and stoma function, postoperative complications, and length of stay. The GelPOINT™ Advanced Access Platform (Applied Medical, Santa Margarita, CA) was used. Eight patients were identified who had undergone single-site surgery with the GelPOINT platform. Six of the 8 patients underwent the first stage, total abdominal colectomy (TAC), and all 8 underwent the second stage (proctectomy/IPAA). The mean operating time for TAC was 242 ± 32 minutes. The mean time until tolerance of clear diet was 1.2 ± 0.4 days, and time until tolerance of regular diet was 3.3 ± 1.2 days. The mean time to stoma function was 1.5 ± 0.55 days, and that for postoperative opioid use was 4.0 ± 1.3 days. The median length of stay was 5 days (range, 3-10 days). There was one postoperative complication. The mean operating time for the proctectomy/IPAA was 283 ± 50 minutes. The mean time until tolerance of clear diet was 1.0 ± 0.5 days, and time until tolerance of regular diet was 3.3 ± 1.1 days. The mean time to stoma function was 1.6 days ± 0.52 days, and that for postoperative opioid use was 3.3 ± 1.4 days. Median length of stay was 4 days (range, 3-9 days). There was one postoperative complication. Technical adaptations that included extracorporeal mesenteric division, rectal eversion, and rotation of the GelPOINT device served to improve the ease and efficiency of the procedure. Single-site TPC-IPAA is both feasible and safe. Incorporation of adapted technical maneuvers can increase efficiency.

    ABSTRACT: Morcellation of a bulky uterus after total laparoscopic hysterectomy (TLH) is a challenge for those dealing with advanced laparoscopic surgery. However, there are no laparoscopic standardized procedures available to date. We developed a laparoscopic cold knife technique with the aim of demonstrating a simple and reproducible method of sectioning and vaginal retrieval of the bulky uterus. From June 2012 to June 2014, patients who underwent TLH for benign indication, with a uterus size over 12 gestational weeks, were prospectively admitted into the clinical study. Before specimen vaginal retrieval, uterine section was achieved by Chardonnens' cold knife with the aim of obtaining two uterus halves sectioned longitudinally and held together only by the posterior cervical wall. We performed the procedure in a containment system to avoid myometrial spillage into the abdomen. Twenty-nine women with a bulky uterus were treated by TLH and the cold knife section technique. The uterine size ranged from 240 to 850 g (median, 460 g), and the average morcellation operative time was 11.3 minutes. All procedures were completed successfully without complications. Our data suggest that the cold knife uterine section technique after TLH is a feasible, simple, and reproducible method of bulky uterus morcellation, even if further research is advisable to fully evaluate the advantages of this procedure.

    ABSTRACT: Reliable closure and infection prevention are the main barriers for implementation of pure transgastric peritoneoscopy. The primary aim of this study was to assess healing of over the scope clip (OTSC) closed gastrotomies. Pure transgastric peritoneoscopy was performed in 7 pigs. The pigs were randomized to 14 or 28 postoperative days (POD) of follow-up. Decontamination of the access route was performed before instrumentation. A full necropsy was performed. Closure was evaluated with histopathological examination of excised gastrorrhaphies. Three pigs were allowed 14 POD of follow-up, and 4 pigs were allowed 28 POD of follow-up. Survival was achieved in 6 of the 7 animals; 1 pig was euthanized due to diffuse peritonitis. Based on our definition, full-thickness healing had only been achieved in a single pig allowed 28 POD. With respect to clinical relevancy, full-thickness healing was deemed achieved in 4 of 6 pigs completing follow-up and in all pigs allowed and surviving 28 POD. Access required repeated punctures and the use of several endoscopic instruments. Full-thickness healing of the gastrotomy was only found in a single case when adhering to the per protocol definition. Endoscopic ultrasonography-guided access was difficult. It lacks reproducibility and needs refinement. Despite a combined decontamination regimen, infectious complications still occurred.

    ABSTRACT: Diagnostic and therapeutic laparoscopy is a known approach in managing patients with penetrating abdominal trauma (PAT). However, multiple controversies exist on indications, contraindications, and its appropriateness. The aim of this study was to evaluate the appropriateness of diagnostic and therapeutic laparoscopy in patients with PAT at Dr George Mukhari Academic Hospital, Pretoria, South Africa. This was a retrospective, observational study. All patients with PAT managed by diagnostic and therapeutic laparoscopy during 2012-2013 were included. Recorded indications and contraindications, the mechanism of injury, the anatomical location of injury, intraoperative findings, reasons for conversion, and adverse outcomes (complications, reoperations and mortality) were analyzed in every case. One hundred fourteen patients were included. Stab injuries were sustained by 81 (71%) patients, and 33 (29%) patients sustained gunshot wounds (GSW) to the abdomen. The conversion rate was 7%. The operation was completed laparoscopically in 106 patients: 79 with stab wounds (74.5%) and 27 with GSW (25.5%). Laparoscopy was diagnostic for 44 patients (41.5%) and therapeutic for 62 patients (58.5%). In total, 13 patients (12%) required re-intervention, and 2 patients died (1.9%). The complications were not specific to the laparoscopic approach. No missed injuries were reported in the study. Diagnostic and therapeutic laparoscopy in patients with PAT is an appropriate management in hemodynamically stable patients or those responsive to initial resuscitation. The location of injuries is not a limiting factor, although it affects placement of ports. The conversion is not a complication but rather the correct way of completing the operation in an appropriate situation. It should be considered in patients with extensive intraabdominal bleeding suggesting the possibility of major vessel injury, a significant deterioration of the patient, and the complexity of injuries requiring a prolonged laparoscopic procedure.

    ABSTRACT: A small percentage of patients fitted with a gastric band still experience "failure." Here, the authors demonstrate the safety and feasibility of band preserving-laparoscopic gastric plication (BP-LGP), which was designed to improve weight loss and decrease gastric band adjustment frequency and thereby improve patient quality of life. All 6 patients involved in this study had a gastric band in place for more than 1 year; the median interval from gastric banding to BP-LGP was 31.7 months (range, 19.7-49.9 months). Five (83.3%) patients were female. Preoperative median body mass index (BMI) at gastric banding was 35.4 kg/m(2) (range, 31.9-43.9 kg/m(2)), median nadir BMI with the gastric band was 25.7 kg/m(2) (range, 20.9-31.0 kg/m(2)), and percentage excess BMI loss (%EBMIL) ranged from 24.3% to 123.6%. Indications for BP-LGP were as follows: chronic gastric prolapse in 2 patients (33.3%), pouch-esophageal dilatation in 3 (50.0%), and insufficient weight loss in 4 (66.6%), which included 2 patients with weight loss failure (%EBMIL of <30%). The 6 patients consecutively underwent surgery from May 2014 to January 2015. No conversion to open surgery was necessary, and no perioperative complication or mortality occurred. Mean operative time was 190 minutes. All patients showed weight loss after revision and showed resolution of troublesome signs and symptoms. Median follow-up after revision was 7.3 months (range, 5.7-10.1 months), median BMI at last follow-up was 27.6 kg/m(2) (range, 22.7-34.0 kg/m(2)), and median %EBMIL was 75.7% (range, 21.0%-103.6%). Median fill volume before revision was 6.1 mL (range, 2.7-11.0 mL), and median fill volume after revision was 0.3 mL (range, 0.0-5.3 mL). Three patients (50%) had an empty band at last follow-up. This novel method of bariatric revision (modified BP-LGP) might have a role as a salvage procedure in patients with impending gastric band failure.

    ABSTRACT: The aim of this study was to evaluate the effect of the percutaneous internal ring suturing (PIRS) technique on testicular vascularization when used for inguinal hernia repair in children. In this prospective study, 49 boys older than 1 year who had been diagnosed with unilateral inguinal hernia were evaluated. Hernias were repaired using the laparoscopic PIRS technique. The testes of each patient were examined using Doppler ultrasound at the preoperative, early postoperative, and late postoperative periods. Peak systolic velocity (PSV), end diastolic velocity (EDV), and resistivity index (RI) of the intratesticular centripetal and testicular capsular arteries were determined. PSV, EDV, and RI of the centripetal and capsular arteries were similar between preoperative, early postoperative, and late postoperative periods, with no statistically significant differences detected. Testicular vascularization was not affected by hernia repair using the PIRS technique in our study. We therefore conclude that PIRS is a safe technique for inguinal hernia repair with respect to testicular vascularization.

    ABSTRACT: Laparoscopic pyloromyotomy (LP) is a well-established approach for treating hypertrophic pyloric stenosis. Although grasping the pylorus with forceps is important in LP, it requires a high level of surgical skill. To make this approach easier, in 2008 we introduced the method of Dozier and Kim, in which a vascular clamp (VC) is used for grasping the pylorus (LP with VC). Here, we retrospectively compared results between traditional LP (TLP) and LP with VC. Forty-three patients underwent LP with VC, whereas 194 patients underwent TLP. Two ports in the umbilicus and the left flank are common in both procedures. Instead of a right flank port, however, in LP with VC, we directly insert a VC to grasp the pylorus. Patients' characteristics were not different between the two groups. There was only one wound infection and no major complication associated with LP with VC, whereas there were three major complications in TLP. Our hospital is a pediatric teaching institution in Japan where many surgeons perform their first LP. Twenty-eight surgeons performed their first LP in our hospital in the past 17 years, and LP with VC was the first LP for nine. The operative time for surgeons' first LP was significantly shorter with LP with VC than with TLP, based on Welch's t test (42.8 versus 54.4 minutes; P = .048). Our results suggest that LP with VC is an easy and safe technique, and it is recommended for beginners in laparoscopic surgery.

    ABSTRACT: Although the cuff of tracheal tubes can reduce airflow leakage and prevent aspiration, excessive intracuff pressure can cause tracheal mucosal injury. Robot-assisted laparoscopic surgery (RALS) can increase intracuff pressure by the Trendelenburg position and pneumoperitoneum. The aim of our current study was to investigate the effect of tracheal cuff shape on the intracuff pressure increase by comparing two different-shaped cuffs during RALS. Ninety-eight patients undergoing RALS were allocated randomly into two groups (tapered-shaped cuff [TSC] and cylindrical-shaped cuff [CSC] groups). The intracuff pressure was measured at nine specific time points: after intubation, immediately after surgical preparation (Trendelenburg position with CO2 insufflation), at 5, 10, 15, 30, 60, and 90 minutes after surgical preparation, and at the end of surgery. Postintubation airway symptoms were measured by assessing sore throat, hoarseness, and excessive cough 1 hour after postanesthesia care unit admission. Intracuff pressure significantly increased during surgery in both groups. The trend of intracuff pressure change decreased in the TSC group compared with the CSC group, although no statistically significant changes were found (P=.450). Also, there were no statistically significant differences in the postintubation airway symptom between the two groups. The TSC tube has a tendency to decrease intracuff pressure change compared with the CSC tube during RALS. However, neither of them was beneficial in preventing intraoperative intracuff pressure increase during RALS.

    ABSTRACT: Detailed preoperative delineation of biliary tract anatomy plays a pivotal role in guiding surgeons completing laparoscopic cholecystectomy (LC) smoothly. Hereby, we retrospectively investigated the potential impact of preoperative magnetic resonance cholangiopancreatography (MRCP) on LC. In this study, clinical data of LC patients who received conventional preoperative examinations from January 2008 to December 2010 (Ctrl group, n=300) versus conventional examinations plus extra preoperative MRCP assessment between January 2011 and December 2013 (MRCP group, n=300) were randomly retrieved. The ratios of conversion to open cholecystectomy and various postoperative morbidities were respectively analyzed. In total, the incidences of operation conversion, postoperative remnant cystic duct stone, and choledocholithiasis in the MRCP group were 12 (4.0%), 1 (0.3%), and 2 (0.7%), respectively, all evidently lower than those in the Ctrl group: 41 (13.7%), 7 (2.3%), and 9 (3.0%). In addition, the MRCP group also presented with fewer cases of bile duct injury and incidental gallbladder carcinoma compared with the Ctrl group (1 versus 5 and 1 versus 2, respectively), although none of the variances was statistically significant. Our results demonstrated that preoperative MRCP had a robust safeguarding effect on LC and deserves further promotion.

    ABSTRACT: To validate the eoSim(®) (eoSurgical Ltd., Edinburgh, Scotland, United Kingdom) simulator for pediatric laparoscopy. Participants were stratified according to their pediatric laparoscopy expertise. Three tasks were tested on the Pediatric Laparoscopic Surgery (PLS) and adapted eoSim simulators. Skill assessment was undertaken using motion analysis software for eoSim tasks and an existing validated scoring system for PLS tasks. Content validity was determined using Likert scale graded feedback responses. Construct validity was evaluated by investigating the respective abilities of the eoSim and PLS assessment tools to differentiate levels of experience. Concurrent validity was investigated by assessing the relationship between PLS and eoSim task completion times. In total, 28 participants (8 experts, 7 intermediates, and 13 novices) were recruited. Content validity results were comparable or more favorable for the eoSim. Construct validity for motion analysis parameters was established for instrument path length (objects transfer, P = .025; suturing, P = .012), speed (suturing, P = .034), acceleration (suturing, P = .048), and smoothness (suturing, P < .001). For all tasks, there were significant differences between level of experience groups for eoSim task completion times and PLS scores (P = .038 to < .001). Significant relationships were found between eoSim and PLS task completion times for the precision cutting and suturing tasks (ρ = 0.298 and ρ = 0.435, respectively). This study demonstrates validity of the adapted eoSim simulator for training in pediatric laparoscopy. Future work should focus on implementing and evaluating the proficiency-based training curriculum that is proposed using construct validity-derived metrics.

    ABSTRACT: An upper gastrointestinal (UGI) series is a standard preoperative test for patients being evaluated for gastrostomy tube placement. We have recently begun to question the value of the radiation-exposing series in patients who tolerate gastric feeds. A retrospective review was conducted in patients who underwent laparoscopic gastrostomy tube placement between 2000 and 2012. Demographics, indication for gastrostomy tube, comorbidities, preoperative imaging, and nutrition were analyzed. Patients with foregut pathology and those who underwent prior gastrointestinal surgery were excluded. Among 695 patients who underwent laparoscopic gastrostomy tube placement, the most common indications were failure to thrive (53%), neurologic disorder (25%), and dysphagia (12%). A UGI series was obtained for 420 patients (60%). Of these, 96 were found to have abnormalities (reflux, aspiration, anatomic). However, only 2 of these patients (0.3%) had a change in management, with 1 patient undergoing the Ladd procedure and 1 having negative diagnostic laparoscopy for suspected malrotation. In the subset analysis of 256 patients tolerating goal gastric feeds, 161 (63%) had a preoperative UGI series with only 2 patients (1.2%) having a resultant change in operative management: 1 undergoing the Ladd procedure and 1 having negative diagnostic laparoscopy. Of the 275 patients who did not have a preoperative UGI series, 1 patient (0.4%) was found to have malrotation postoperatively after two coins became lodged in the duodenum. This patient subsequently underwent an elective Ladd procedure. We found minimal impact of an UGI series during evaluation for gastrostomy alone. These studies may be able to be reserved for those with clear clinical indications.

    ABSTRACT: Recently a retrospective study has been published describing a significant correlation of immediate postoperative leukocytosis (IPLC) and a favorable pathological Gleason score (pGS) in patients undergoing robotic-assisted radical prostatectomy (RARP). The aim of the present study was to prospectively validate these results on an external dataset. In total, 346 patients undergoing RARP as first-line therapy for localized prostate cancer were included. Clinical and histopathological parameters, criteria of IPLC, and pGS were recorded prospectively. Potential association between IPLC and pGS was evaluated by univariate and multivariate analyses. IPLC was found in 77.2% (n = 267) of all patients with a median leukocyte blood count (LBC) of 12.5 × 10(9)/L (interquartile range, 10.2-15 × 10(9)/L). Of these, in 255 patients IPLC was found within the range of 10-20 × 10(9)/L, whereas an IPLC of >20 × 10(9)/L was found in only 12 patients. Of the patients, 49.1%, 40.5%, and 10.4% presented with a pGS6, pGS7, and pGS8-10 tumor, respectively. There was neither a univariate nor a multivariate correlation between IPLC and pGS. Furthermore, no significant correlation could be detected between IPLC and other clinical, intraoperative, or histopathological criteria. In 175 (66%) patients with IPLC normal LBC levels were measured on postoperative Day 4. IPLC was not associated with more favorable tumor biology (lower pGS, better tumor stage) and not influenced by patient conditions (age, body mass index, American Society of Anesthesiologists score, smoking) or intraoperative parameters (blood loss, operating time, surgeon). In addition, there was no significant correlation with serious complications (Clavien-Dindo Grade 3a/b) within a period of 90 days.

    ABSTRACT: Although the minimally invasive endoscopic Stretta procedure is being increasingly used as an alternative strategy to manage gastroesophageal reflux disease (GERD), the benefits of this procedure have to be further evaluated in clinical settings. This prospective observational study assessed the short-term and midterm outcomes associated with laparoscopic Toupet fundoplication (LTF) and the Stretta procedure. From January 2011 to January 2012, we allocated 80 patients to LTF and 85 to the Stretta procedure. Primary outcome measures, including symptom scores of heartburn, regurgitation, chest pain, belching, hiccup, cough, and asthma, as well as proton pump inhibitor (PPI) use, were analyzed at midterm follow-up (1-3 years). Of the 165 patients, 125 patients following LTF (n=65) or the Stretta procedure (n=60) completed the designated 3-year follow-up and were included in the final analysis. At the end of the 3-year follow-up, the symptom scores were all significantly decreased compared with the corresponding values before the two procedures in both groups (P<.05). After LTF and the Stretta procedure, 47/65 (72.3%) and 41/60 (68.3%) patients, respectively, achieved complete PPI therapy independence (72.3% versus 68.3%, P=.627). Comparing with LTF, however, the Stretta procedure had less effect on improving typical symptoms of heartburn, regurgitation, and chest pain and reducing the rate of re-operation (11.8% versus 0%, P=.006). LTF and the Stretta procedure were equally effective in controlling GERD symptoms and reducing PPI use. However, LTF can achieve more improvement on typical symptoms and has a lower rate of re-operation.

    ABSTRACT: The diagnosis of side-branch intraductal papillary mucinous neoplasms (IMPNs) is increasingly more common, but their appropriate management is still evolving. We recently began performing laparoscopic hand-assisted enucleation or duodenal-sparing pancreatic head resection for these lesions with vigilant postoperative imaging. Seventeen patients with pancreatic cystic lesions were included in this single-center retrospective review from January 1, 2008 to March 30, 2013. Indication for surgical intervention was growth in size of the cyst, symptoms, cyst size >3 cm, and/or presence of a mural nodule. Twelve patients underwent laparoscopic hand-assisted enucleation, and 5 patients underwent laparoscopic hand-assisted pancreatic head resection. The mean age of patients was 64 years old. The most common presenting symptom was abdominal pain. The indication for surgical intervention was growth in the cyst or symptoms in the majority of patients. Fourteen lesions were in the head/uncinate, two were in the pancreatic body, and one was in the tail. Final pathology was consistent with side-branch IPMN in 13 patients (1 with focal adenocarcinoma). Three patients had serous cysts, and 1 had a mucinous cyst. Three patients developed pancreatic leaks, which were controlled with intraoperative placed drains, whereas 1 patient required additional drain placement. Median time from surgery to latest follow-up imaging is over 2 years. No patients have developed recurrent cysts or adenocarcinoma. Duodenal-sparing pancreatic head resection or pancreatic enucleation for patients with presumed side-branch IPMN is a safe and efficacious option, in terms of both operative outcomes and postoperative recurrence risk.

    ABSTRACT: Treatment of severe reflux after laparoscopic sleeve gastrectomy (LSG) may require conversion to Roux-en-Y gastric bypass (RYGB). We conducted a pilot study to evaluate the feasibility and effectiveness of performing laparoscopic anterior fundoplication with posterior crura approximation (LAF/pCA), in selected patients, to correct the reflux without conversion to RYGB. From October 2012 to April 2013, 6 patients with confirmed severe de novo reflux after LSG were treated with LAF/pCA. All patients were females with a mean age of 41.5±14.2 years. All patients had lost weight after initial LSG. The percentage excess body mass index (BMI) loss (%EBL) was 61.2±33.2%. The mean time from the initial LSG to LAF/pCA was 33.2±12.5 months. Four patients had reduction of gastric fundus size. One patient required resleeving. Reflux resolved immediately in all patients with a follow-up of 18.5±2.7 months. All patients continued to lose weight, with %EBL reaching 75.5±22.9% and a mean BMI of 32±7.3 kg/m(2). LAF/pCA with reduction of gastric fundus size, when needed, may be considered an alternative option to correct severe reflux after LSG in selected patients.

    ABSTRACT: Distal obstruction of ventriculoperitoneal (VP) shunts is a major problem in the treatment of hydrocephalus. To avoid this complication, we describe a simple method using the falciform ligament to place and hold the distal catheter in the right subdiaphragmatic space, preventing catheter migration and distal obstruction. We retrospectively collected data of all VP shunt insertion and revision for adults with idiopathic normal-pressure hydrocephalus between November 2011 and September 2013. All of these were done using the "falciform technique," with the distal catheter portion performed laparoscopically. No exclusion criteria were applied. A neurosurgeon and a laparoscopic surgeon were involved in each case. The falciform ligament was used to tether the distal catheter above the liver, with the distal tip of the catheter reaching the hepatic flexure to allow for drainage directly into the right paracolic gutter. Baseline, operative, and postoperative data were collected and analyzed. In total, 58 patients underwent a shunt procedure during the period of study. The majority (74%) underwent new VP shunt placement, and 26% underwent revision and replacement for catheter obstruction. The female to male ratio was 1.14:1. Mean age was 67.3±17.5 years. Revisions due to distal catheter obstruction were subsequent to previous surgery placement. Median follow-up was 329 days. Three patients (5%) had proximal catheter obstruction requiring shunt revision. None of the patients (0%) was found to have distal obstruction at the end of the study period at the most recent follow-up. The faparoscopic falciform technique significantly reduces the rate of distal VP shunt obstruction in adults with idiopathic normal-pressure hydrocephalus. Continued follow-up is needed to confirm long-term patency of the catheter.
