A prophylactic ureteral localization stent (PULSe) placed by urologists aids in intraoperative localization and detection of suspected ureteral injury during complex colorectal surgery (CRS) cases. We evaluated the incidence and management of urologic-induced complications secondary to PULSe placement during CRS cases at a single center.
We performed a retrospective review of all patients who underwent cystoscopy and PULSe placement at the time of CRS over a 12-month period. Bilateral 5 French ×70-cm TigerTail® (Bard Medical Division, Covington, GA) PULSe devices were placed without assistance of routine fluoroscopy.
Ninety-nine patients (mean age, 58.1 years; range, 17–88 years) underwent bilateral PULSe placement, with a male:female ratio of 44:55 and a mean body mass index of 26.8 (17.0–38.6) kg/m2. Mean pre- and postprocedural creatinine levels were 0.91 and 1.01 mg/dL, respectively. Twenty-two of 99 (22%) cases utilized a guidewire to aid in placement of PULSe. Four Clavien grade IIIb complications occurred: mucosal edema, reflex anuria, ureteral perforation, and ureteral obstruction secondary to significant clot burden. Three of the grade IIIb complications were managed endoscopically with double-J stent placement. The ureteral perforation case required percutaneous nephrostomy tube placement. Subgroup analysis of the four grade IIIb complications revealed a mean age of 62.3 years, body mass index of 26.98 kg/m2, and pre- and postprocedural creatinine levels of 0.95 and 4.83 mg/dL, respectively. Only one of the four grade IIIb complications utilized a guidewire prior to PULSe placement.
The incidence of Clavien grade III urologic-induced complications during PULSe placement is approximately 2% (4/188). Mandatory adoption of fluoroscopy and guidewires may be required to minimize complications of PULSe placement.
Obesity is a common disease affecting young adults and adolescents worldwide. This study aims to delineate the role of laparoscopic sleeve gastrectomy (LSG) in weight loss and associated comorbidities to adolescents and young adults.
This study is a retrospective analysis of a prospective cohort of all young adults 16–22 years old who underwent LSG for morbid obesity and were followed up for 24 months. Demographic data, weight loss, and the status of several comorbidities, such as diabetes mellitus, hypertension, and dyslipidemia, were assessed at postoperative Months 1, 3, 6, 12, 18, and 24.
Overall, at baseline and after 24 months of close follow-up of 37 adolescents and young adults who had undergone LSG, the body mass index of the patients was 46.93 ± 6.07 kg/m2 versus 26.2 ± 3.6 kg/m2 (
LSG represents a safe and attractive treatment strategy for morbidly obese adolescents and young adults with comorbidities. In this study group excellent resolution of excess weight and comorbid conditions is achieved 2 years after LSG.
Several studies have demonstrated that laparoscopic colonic resection has significant benefits in comparison with open approaches in patients with benign and malignant disease. The proportion of colonic and rectal resections conducted laparoscopically in Austria is not currently known; the aim of this study was to evaluate the current status of laparoscopic colonic surgery in Austria.
A questionnaire was distributed to all general surgical departments in Austria. In collaboration with IMAS, an Austrian market research institute, an online survey was used to identify laparoscopic and open colorectal resections performed in 2013. The results were compared with data from the National Hospital Morbidity Database (NHMD), in which administrative in-patient data were also collected from all general surgical departments in Austria in 2013.
Fifty-three of 99 surgical departments in Austria responded (53.5%); 4335 colonic and rectal resections were carried out in the participating departments, representing 50.5% of all NHMD-recorded colorectal resections (
The proportion of colorectal resections that are carried out laparoscopically is low (26.1%). Technical challenges and a learning curve with a significant number of cases may be reasons for the slow adoption of laparoscopic colonic surgery.
Published studies on laparoscopic surgery for transverse colon cancer are scarce. More studies are necessary to evaluate the feasibility, safety, and long-term oncologic outcomes of laparoscopic surgery for transverse colon cancer.
From April 1996 to December 2010, 102 consecutive patients with stage II or III disease who had undergone curative resection for transverse colon cancer were enrolled. Seventy-nine patients underwent laparoscopy-assisted colectomy (LAC), whereas 23 patients underwent conventional open colectomy (OC). Short- and long-term outcomes of the two groups were compared.
The OC group had a larger tumor size (7.6 ± 3.4 cm versus 5.2 ± 2.3 cm,
Laparoscopic surgery for transverse colon cancer has better short-term outcomes compared with open surgery, with acceptable long-term outcomes. As in colorectal cancer of other sites, laparoscopic surgery can be a feasible alternative to conventional surgery for transverse colon cancer.
Studies comparing the prognostic results between laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) in cervical cancer reported contradictory results. We aimed to evaluate the prognostic and safety roles of LRH by pooling studies in a meta-analysis.
Original articles were searched in PubMed, EMBASE, and the Cochrane Library. The survival results (5-year disease-free survival [DFS], 5-year overall survival [OS], and recurrence rate [RR]), safety parameters (intra-, peri-, and postoperative complication rates and postoperative bowel or bladder recovery days), efficiency parameters (pelvic/para-aortic lymph nodes removed), and other parameters (operative time, estimated blood loss, and hospital of stay) between the two approaches were reviewed.
For the 2922 cases identified, DFS, OS, and RR did not differ in balanced prognostic factors, including lymph node metastasis, Stage IIB or above, non–squamous cancer histology, grade G3, lymphovascular space invasion, tumor size ≥4 cm, and positive parametrial and vaginal margin rates. Meanwhile, LRH was associated with higher complication rates and a shorter time to the recovery of bowel or bladder function than for ARH. The number of removed pelvic or para-aortic lymph nodes did not significantly differ. Other parameters showed LRH was associated with a longer operative time, less blood loss, and a shorter length of hospital stay. The survival and prognostic results did not differ in balanced prognostic factors.
LRH is safe and has lower operative complication rates than ARH.
Technologic advances and superior survival with mechanical circulatory support (MCS) have led to an expanding population that develops intraabdominal conditions requiring intervention. Whether laparoscopy can be performed without detrimental effects on hemodynamics and device function is not well described.
Effects of laparoscopy performed on MCS were retrospectively assessed. Intraoperative hemodynamics and device function were compared with the same time interval 24 hours prior to surgery using intrapatient paired
Twelve patients with ventricular assist devices or total artificial hearts underwent laparoscopy from 2012 to 2014. Median follow-up was 116 days. Operations included cholecystectomy, diagnostic laparoscopy, gastrojejunostomy, and gastrostomy. There were no differences between preoperative and intraoperative mean arterial pressure, heart rate, and inotrope or vasopressor requirements (
Laparoscopy can be performed on MCS with low morbidity and mortality and minimal perturbations in hemodynamics and device function.
Hem-o-Lok® clips (HOLCs) (Weck® Surgical Instruments, Teleflex Medical, Durham, NC) are widely used for controlling the lateral pedicles in laparoscopic radical prostatectomy, but intravesical HOLC migrations have been reported in more and more studies. This study aimed to summarize clinical presentations, management, and outcomes of these patients.
Six patients with intravesical HOLC migration were retrospectively identified from 750 consecutive patients who underwent robot-assisted laparoscopic prostatectomy between 2005 and 2014 performed by a single surgeon. The PubMed database was also searched for Hem-o-Lok clip migration after laparoscopic prostatectomy.
The incidence of intravesical HOLC migration in this study was 0.8% (6/750). In total, 22 patients were reported, including six from the current series. Three types of migrations were classified: Type I migration resulted in obstructive lower urinary tract symptoms 2–8 months after prostatectomy, whereas Type II migration led to stone formation, gross hematuria, or bladder spasm; in Type III migration, patients had spontaneous expulsion of the HOLC weeks after surgery.
Although the incidence of intravesical HOLC migration is relatively low, Type I migration with long-term sequelae remains a concern. The use of HOLCs adjacent to anastomosis should be minimized, and any loose clip must be retrieved to reduce complications.
The manual dexterity of a surgeon is known to be related with surgical proficiency. Recently, as an objective measurement of surgical skills, inanimate methods using several types of simulators have been introduced. Using these simulators, we aimed to investigate the impact of manual dexterity on laparoscopic and robotic surgical proficiency.
Fellow surgeons, surgical residents, and medical students (
Manual dexterity was not a significant factor for performance time during laparoscopic suturing, which was more influenced by participants' surgical experiences. In robotic suturing, the performance score was impacted significantly by manual dexterity in terms of ambidexterity rather than dexterity speed. For an easy robotic suturing task, the gap of proficiency between the lower and higher ambidexterity groups was decreased successively with each of the three sessions. However, that gap in cases with a difficult task was maintained consistently throughout all three sessions.
The degree of ambidexterity was an initial predictor for proficiency with simulated robotic suture. However, this relation could be lessened through a few sessions of training, although for a more difficult task further repetitions would be needed.
The purpose of this report is to describe a tension-free repair we have used successfully in 12 patients with large hiatal defects. It is based on the creation of a web-shoelace pattern of polypropylene (Prolene®; Ethicon, Somerville, NJ) suture of the crura that functions as a barrier, with the advantages of being stronger and more economical than a mesh without the potential complications that may follow mesh repair or suture repair of a large hiatus hernia without mesh. Despite a success rate of 85%–95% reported in large series with a mid- and long-term follow-up evaluation, significant complications have been associated with hiatus hernia repair. Some of these complications include a slipped Nissen repair with intrathoracic wrap migration and hiatal hernia recurrence, resulting from inadequate closure of the crura, fundoplication disruption, or dehiscence of the hiatoplasty.
From June 2013 to June 2014, we have used this technique on 12 patients (6 women and 6 men). Only patients with a large hiatus hernia of >4 cm were enrolled in this study. All patients underwent laparoscopic Nissen fundoplication and hiatoplasty using our technique. They were all severely symptomatic with dysphagia, retrosternal pain, gastroesophageal reflux disease, and respiratory symptoms at night.
Of the 12 patients who underwent this type of repair, all of them have reported good to excellent functional and symptomatic outcomes with minimal morbidity, no deaths, and no recurrence.
It is our belief that when a correct repair of the hiatus is not achieved with three stitches, adding more sutures will not lead to a tension-free repair, and this hiatoplasty will have an increased risk of dehiscence. It is for this reason that we recommend using our technique instead of using simple nonabsorbable sutures or a prosthetic mesh.
Nissen fundoplication is the current gold standard for surgical management of gastroesophageal reflux disease; however, a magnetic antireflux device is now an alternative surgical procedure. The early literature shows good reflux control with minimal complications, and therefore placement of these devices is growing in popularity. As more of these devices are placed, there will be cases in which they will need to be removed. A laparoscopic method for removing the device is presented here.
We present a case of a 42-year-old female with history of gastroesophageal reflux who underwent a laparoscopic placement of a magnetic lower esophageal sphincter augmentation device and repair of a small hiatal hernia. She had a complicated postoperative course before presenting to our institution with a 2-year history of persistent dysphagia and requesting the device be removed. Laparoscopic removal of the device was performed.
After laparoscopic removal of the patient's magnetic lower esophageal sphincter augmentation device, she had subjective improvement in her dysphagia but is now being medically managed for gastroesophageal reflux and for delayed gastric emptying.
Laparoscopic removal of magnetic lower esophageal sphincter augmentation devices will sometimes be necessary and may be challenging if the surgeon encounters significant scar tissue around the gastroesophageal junction. Postoperative complications are similar to those encountered with foregut surgeries and include postoperative delayed gastric emptying.
Surgically altered anatomy complicates endoscopic procedures of the pancreaticobiliary tree. Biliary strictures have been managed using percutaneous transhepatic techniques.
In recent years device-assisted enteroscopy (e.g., double balloon enteroscope [DBE]) has been used to gain access to the common bile duct. The length of the scope and its narrow, 2.8-mm working channel limit the use of standard endoscopic retrograde cholangiopancreatography (ERCP) devices. Therefore, shorter enteroscopes for ERCP have been developed. A fully covered self-expandable metallic stent (fcSEMS) cannot be used through the narrow channel. In conventional anatomy, benign biliary strictures have been treated using fcSEMS, requiring fewer endoscopies compared with multiple plastic stenting.
Here we report the first case of fcSEMS deployment through the working channel of a novel, long DBE with a 3.2-mm working channel, and 2 cases with the conventional narrow-channel DBE, using the rendezvous technique, with fcSEMS insertion on a wire running along the enteroscope.
These new techniques, here used on benign biliary strictures, are described in detail.
Elective cholecystectomy is a high-volume, simple procedure, well suited for the development of a pediatric robotic surgery program. Surgical robot software, by “reversing” the surgeon's hands, simplifies single-site cholecystectomy through a single incision at the umbilicus.
Data were reviewed on the first nine children who had robotic cholecystectomy, with the Da Vinci® Surgical System (Intuitive Surgical Inc., Sunnyvale, CA) device, at our institution. All cases were performed by a single surgeon, proctored by an experienced robotic general surgeon.
There were 9 patients: the first 4 patients had robotic multiport cholecystectomy, and the last 5 had robotic single-site cholecystectomy. Eight were girls. They were 10–18 years of age (median, 14 years). Diagnoses were biliary dyskinesia (
Robotic cholecystectomy is safe and efficacious and is a suitable introductory procedure for pediatric surgeons considering a robotic surgery program. Single-site robotic cholecystectomy is a cosmetically attractive option but takes longer than multiport robotic cholecystectomy.
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
Our results suggest that LP with VC is an easy and safe technique, and it is recommended for beginners in laparoscopic surgery.
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.
Different approaches of dealing with mucosal injury during pyloromyotomy for hypertrophic pyloric stenosis have been described. There is, however, no consensus on the best technique to use. We conducted a survey among International Pediatric Endosurgery Group (IPEG) members on their experience of mucosal injuries during pyloromyotomy, the way in which these were handled, any modification in subsequent postoperative care, and impact on outcome.
A confidential survey was sent to IPEG members querying demographic data, number of pyloromyotomies performed, operative approach, incidence of mucosal injury, intraoperative management, and postoperative consequences. Statistical analysis was performed to determine factors associated with complications and outcome.
In total, 231 mucosa injuries were included in the study. Of these, 93% were noticed intraoperatively. Cases were nearly equally distributed between laparoscopic (49%) and open (51%) procedures, and the risk of mucosal injuries was no different between the two. Most surgeons addressed mucosal perforation with primary mucosal repair (70%), whereas a minority (27%) performed full-thickness closure, rotation, and repyloromyotomy in a different quadrant. Common alterations in management included delay in feeding (84%), longer hospital stay (30%), and contrast study before feeding (12%). The vast majority of patients had no adverse sequelae after a mucosal injury (96%), but three patients underwent re-operation. No correlations were found between repair method and complications.
Mucosal injuries that are noticed and addressed intraoperatively resulted in few complications, regardless of the repair method. Among the queried surgeons, primary mucosal repair is the current standard of care. Primary mucosal repair is equivalent to full-thickness closure in terms of complications and outcome.
Gastrojejunostomy (GJ) tubes are an option for durable enteral access for critically ill infants with congenital cardiac disease who struggle with obtaining adequate nutrition.
Infants weighing less than 10 kg with cardiac disease who received placement of a laparoscopic GJ tube from November 2011 to January 2015 were reviewed. The operative technique used an umbilical port for the camera and a single stab incision for the gastric access site. After insufflation to 5–8 mm Hg, the stomach was suspended to the abdominal wall, after which a dilator was maneuvered into a postpyloric position using laparoscopic visualization and fluoroscopy, and a glidewire was passed into the duodenum. The GJ tube was then fluoroscopically threaded over the glidewire; final position was confirmed by contrast injection.
There were 32 laparoscopic GJ tube placement operations performed; 7 (21.9%) of these tubes were standard single-unit GJ tubes, and 25 (78.1%) were low-profile gastrostomy tubes modified with a nasojejunal feeding tube threaded through the feeding port. Median patient age was 3.5 months (range, 0.75–11 months), with a median weight of 4.2 kg (range, 2.4–7.4 kg). Congenital defects were varied, including hypoplastic left heart syndrome and pulmonary vein stenosis. Median operative time was 62 minutes for isolated GJ placement (range, 35–114 minutes). There were three postoperative complications, resulting in a 30-day complication rate of 9.4%. Thirty-day mortality was 9.4% with no mortality related to the operation.
Laparoscopic GJ tube placement may be performed safely in infants with cardiac disease and allows these patients to receive adequate nutrition despite intolerance of gastric feeding.
Three-dimensional (3D) imaging has been shown to enhance depth perception and facilitate operations in training box studies and in adult laparoscopy. However, there are no data on 3D vision in small working spaces, which are common pediatric surgery. Therefore, this study examined the impact of monoscopic versus stereoscopic visualization in large versus small working spaces in individuals with varying surgical expertise.
Twenty-four individuals with varying surgical expertise (experts, surgical residents, and surgical novices) were involved in the study. Participants were asked to perform four tasks in large (24- × 30- × 50-cm) and small (9- × 11- × 18-cm) training boxes, using two-dimensional and 3D imaging. Sixteen standardized procedures were performed by each participant. Primary outcome measure was performance time. Secondary outcome parameters included the number of errors and subjective depth perception.
Surgical novices showed a shorter performance time and lesser total number of errors in large and small training boxes using 3D imaging. Residents achieved a significantly shorter performance time in the large and lesser number of errors in the small box. With 3D vision experts performed laparoscopic suturing in the small box and target touching in both boxes significantly faster. The overall performance time and total number of errors of experts were not different in the two boxes. Subjective depth perception with 3D vision in the small box in all groups and in the small box in surgical novices was significantly better.
We identified several advantages of 3D vision in individuals with varying surgical expertise. However, the benefits were rather experienced by surgical novices and residents than by experts. Differences in performance time and number of errors were similar in the large and small simulator boxes.
Laparoscopic gastrostomy is a widely used interventional procedure in pediatric surgery. We report comparative data for two endosurgical methods for the fixation of the stomach against the abdominal wall, using the U-stitches technique and the Saf-T-Pexy® (Halyard Health Inc., Alpharetta, GA) system.
Within the period from January 2012 to June 2014 we performed 24 operations involving laparoscopic placement of a gastrostomy tube using U-stitches (Group I) and 24 operations using the Saf-T-Pexy system (Group II). The two groups of patients were compared in terms of demographics and intraoperative and postoperative results.
No statistical difference (
Use of the Saf-T-Pexy system is a simple and efficient method for gastropexy involving placement of gastrostomy tubes that significantly reduces the number of postoperative complications.
