Laparoscopic Transumbilical Cholecystectomy Without Visible Abdominal Scars

Introduction  We present a novel surgical technique for cholecystectomy utilizing three laparoscopic ports placed through the umbilicus. This new method is natural orifice transumbilical surgery (NOTUS) and describes a laparoscopic operation that can be performed with all incisions placed within the umbilicus obviating visible abdominal scars. Objectives  To develop a novel laparoscopic surgical technique for cholecystectomy utilizing only transumbilical incisions. Summary Background Data  Natural orifice translumenal endoscopic surgery (NOTES) has become an exciting area of surgical development. Significant limitations to this surgical concept, however, are lack of surgical expertise and appropriate flexible instrumentation. An alternative and competing technology to NOTES is NOTUS. Methods  We describe a patient in whom a laparoscopic surgical technique for cholecystectomy utilized incisions all placed entirely within the umbilicus. This new technique is called NOTUS and describes a laparoscopic operation that can be performed without visible abdominal scar. Results  The operative time was 70 min. There were no intraoperative complications. The patient did well postoperatively and was discharged on the same operative day. There were no postoperative complications at 2 months follow-up. Conclusion  Cholecystectomy performed through laparoscopic incisions placed within the umbilicus was technically feasible and safe in our patient. Development of advanced flexible instrumentation and visualization platforms may facilitate this new operative approach. Further advantages of NOTUS cholecystectomy compared to conventional laparoscopic cholecystectomy will ultimately require a randomized clinical trial.     

Totally NOTES (T-NOTES) transvaginal cholecystectomy using two endoscopes: preliminary report

Background

Clinical applications of transvaginal Natural Orifice Transluminal Endoscopic Surgery (NOTES) are still limited in the literature, mostly case reports performed by hybrid procedures with laparoscopic assistance. Avoiding complications from incisions is the main goal for natural orifice surgery. This study reports on a technique developed at our institution that uses two endoscopes inserted into the vagina to perform a Totally NOTES (T-NOTES) transvaginal cholecystectomy, and describes preliminary results.

Methods

IRB approval was obtained at the institution for transvaginal NOTES clinical trials, and informed consent was obtained. The technique of T-NOTES transvaginal cholecystectomy was clinically applied in four female patients with symptomatic cholelithiasis, and data were prospectively documented. Transvaginal NOTES access was obtained by direct vaginal incision, and two endoscopes were simultaneously introduced in the abdominal cavity. Dissection was accomplished with available endoscopic instruments. Ligation of cystic duct and artery was performed using endoscopic clips. Vaginal closure was achieved using the direct-vision sutured technique.

Results

The technique was successfully performed in the four patients. Insufflation and spatial orientation was of good quality. Mean operative time was 210 min. There were no complications during the 30-day follow-up. Postoperative course was uneventful, and patients were released from the hospital on the first postoperative day.

Conclusion

Tranvaginal T-NOTES using two endoscopes provides a feasible method for natural orifice cholecystectomy using available technology. Large-series studies are needed to evaluate the results with respect to safety of the approach.     

New minimally invasive approaches for cholecystectomy: Review of literature

Laparoscopic cholecystectomy is the most commonlyperformed abdominal intervention in Western countries. In an attempt to reduce the invasiveness of the procedure, surgeons have developed single-incision laparoscopic cholecystectomy(SILC), minilaparoscopic cholecystectomy(MLC) and natural orifice transluminal endoscopic surgery(NOTES). The aim of this review was to determine the role of these new minimally invasive approaches for elective laparoscopic cholecystectomy in the treatment of gallstone related disease. Current literature remains insufficient for the correct assessment of emerging techniques for laparoscopic cholecystectomy. None of these procedures has demonstrated clear benefits over conventional laparoscopic cholecystectomy. SILC cannot be currently recommended as it can be associated with an increased risk of bile duct injury and incisional hernia incidence. NOTES cholecystectomy is still experimental, although hybrid transvaginal cholecystectomy is gaining popularity in clinical practice. As it is standardized and almost identical to the standard laparoscopic technique, MLC could lead to limited benefits without exposing patients to increased postoperative complications, being therefore adoptable for routine elective cholecystectomy. Technical challenges of SILC and NOTES cholecystectomy could be addressed with the evolution of new surgical tools that need to catch up with the innovative minds of surgeons. Regardless the place of these approaches in the future, robotization may be necessary to impose them as standard treatment.     

Evaluation for transvaginal and transgastric NOTES cholecystectomy in human and animal natural orifice translumenal endoscopic surgery

Background/purpose  Natural orifice translumenal endoscopic surgery (NOTES) is a novel concept using an endoscope via a translumenal access for abdominal surgery. This study was designed to evaluate the feasibility and technical aspects of NOTES cholecystectomy from our experience on humans and animals. Methods  NOTES cholecystectomies were performed in 12 animal experiments, including 8 pigs (6 by transgastric and 2 by transvaginal accesses) and 4 dogs (4 transvaginal accesses), and a human female cadaver. Results  The entire gallbladder could be removed under direct vision in all experiments. The average time was 60 min by transgastric and 40 min by transvaginal in animals. It was 87 min for human transvaginal cholecystectomy. In all animal and human procedures, there was no major complication concerning the operation. Discussion  The transvaginal route may be the easiest route for abdominal NOTES. Percutaneous endoscopic gastrostomy (PEG) allowed the safe performance of a controlled gastric perforation and shortened the time. The hybrid method allowed performance of a safe procedure and shortened the time. Conclusions  Transvaginal and transgastric NOTES cholecystectomy is technically feasible and safe in both humans and animals. New instrumentation needs to be developed to perform a pure NOTES cholecystectomy without transabdominal assistance.     

NOTES: transvaginal for cancer diagnostic staging: preliminary clinical application

Laparoscopy is now a reliable method for staging gastrointestinal cancer, orienting the therapy, and avoiding unnecessary laparotomy. Natural orifice transluminal endoscopic surgery (NOTES) is an emerging concept with potential advantages for patient recovery. The first case of clinical diagnostic application of transvaginal NOTES for diagnostic cancer staging is presented. Informed consent and Institutional Commission approval were obtained for transvaginal clinical trials. On February 28, 2007, a patient with elective surgical indication for diagnostic cancer staging was submitted to transvaginal NOTES procedure, and intra- and postoperative parameters were documented. In a 50-year-old female patient presenting with ascitis, diffuse abdominal pain, and weight loss for 2 months, diagnosis of peritoneal carcinomatosis was suspected, which was also found when a CT scan was performed. Transvaginal NOTES was used for diagnostic staging of the patient, using a colonoscope introduced into the abdomen through a small incision in the vagina. Biopsies of liver, diaphragm, ovaries, and peritoneum were successfully performed. Operative time was 105 min, vaginal access and closure was obtained in 15 min. Abdominal inventory was reliable, and all 16 biopsies taken were positive for ovarian adenocarcinoma. The patient was dismissed 48 hours after the procedure without complications. Recent literature and experience of the study group suggest possibilities for preliminary clinical applications by transvaginal natural orifice surgery for diagnostic purposes.

Natural orifice surgery applied for colorectal diseases

Clinical natural orifice surgery has been applied to abdominal surgery in recent years, mostly using transvaginal and transgastric access. Rectal and transcolonic natural orifice transluminal endoscopic surgery (NOTES) were tested in animal and cadaver models by a few research groups. Despite the potential advantages of transcolonic NOTES for colorectal diseases, it has not yet been clinically applied. The first successful series of human applications of transcolonic NOTES in the literature from the NOTES Research Group in Brazil provide new possibilities in the field in new transrectal procedures for rectal cancer and benign disease. Successful first human reports on Transcolonic NOTES potentially brings new frontiers and applications for minimally invasive surgery. The treatment of colorectal diseases through flexible Perirectal NOTES Access is a promising new approach alongside existing laparoscopic and open surgery to improve patient care.     

Transvaginal laparoscopically assisted endoscopic cholecystectomy: preliminary clinical results for a series of 43 cases in China

Background  

Transvaginal cholecystectomy has been performed successfully at several research institutions worldwide using natural orifice transluminal endoscopic surgery (NOTES) techniques. However, it is a growing new surgical concept in China. Several technical challenges hinder the safe clinical application of NOTES. This study investigated transvaginal endoscopic cholecystectomy performed with the assistance of a single umbilical trocar and achieved helpful initial clinical experience.     

NOTES – Cholezystektomie ohne sichtbare Narben

The use of natural orifices for operations in the abdominal cavity (natural orifice transluminal endoscopic surgery, or NOTES) could be a conclusive development in the field of minimally invasive surgery. Early in the 1990s we had experiences with posterior colpotomy for removal of specimens in laparoscopic surgery. This is why we use the transvaginal approach in NOTES and combine it with a trocar hidden in the umbilicus. With this technique we could perform cholecystectomy without a visible scar. The operation could become routine also because of the use of our well-known rigid optics and instruments. From June 2007 until April 2008 we operated on 57 patients using this method. All operations finished successfully, and the mean operation time was 54 min. There was one complication. An abscess in the Douglas room had to be evacuated laparoscopically. All other postoperative courses were uneventful. After a minimum follow-up of 3 months, none of the patients had symptoms in the vagina or during sexual intercourse.

Laparoscopic assisted transvaginal cholecystectomy: Single centre preliminary experience

BackgroundNatural Orifice Transluminal Endoscopic Surgery (NOTES) is a new approach that allows abdominal surgery to be performed through a natural orifice such as the oral cavity, vagina or rectum. We present our preliminary experience of laparoscopic assisted transvaginal cholecystectomy (LATC).MethodsWomen affected by cholelithiasis, age below 65 years, BMI under 30, ASA I or II, previous full-term pregnancies, and without previous abdominal surgery underwent LATC. Patients' biographic data, operative time, intraoperative and postoperative complications were collected.ResultsWe performed 21 LATCs. Median operative time was 58 min. There were no intraoperative complications. The postoperative course was uneventful in all patients. At 1 year there were no complications and no impaired sexual activity.ConclusionsThe results of NOTES are promising, but currently only hybrid NOTES can be safely performed. LATC seems to guarantee better cosmetic results, less postoperative pain, faster mobilization and shorter hospitalization than laparoscopic cholecystectomy.     

NOTES transvaginal cholecystectomy: preliminary clinical application

Background Natural orifice translumenal endoscopic surgery (NOTES) is an emerging concept in the recent literature that could lead to potential benefits in clinical applications. Restricted to animal experiments, however, human procedures have not yet been published. Because of the technical and ethical challenges involved in perforation and closure of a healthy organ—as is also seen in operating via the transgastric route—and because of the lack of understanding of the physiopathology and infection risk with these approaches, they have not been applied in the clinical setting. Thus the present study, based on previous animal experiments, describes preliminary clinical application in four cases of transvaginal NOTES cholecystectomy, and discusses safety, feasibility, and potential benefits of the method. Methods Preliminary acute and survival animal experiments developed by the NOTES Research Group at our institution solved such technical problems for transvaginal NOTES as spatial orientation, insufflation, and instrumentation, making possible the introduction of NOTES as a clinical application. The trials were approved by ethics committee of our institution, and informed consent was obtained from all patients. Since 13 March 2007, four female patients with elective surgical indication for cholecystectomy have undergone transvaginal NOTES cholecystectomy. All intraoperative and postoperative parameters were documented. Vaginal access was achieved under direct vision with conventional instruments, and a 2-channel colonoscope was inserted into the abdominal cavity. After endoscopic insufflation to achieve pneumoperitoneum with CO₂, instruments were inserted through and alongside a colonoscope, allowing successful NOTES cholecystectomy in all patients, with vaginal extraction of the gallbladder. The vaginal wound was closed by direct vision using conventional instruments. Results The procedure was successful in all patients, with operative time of 45–115 min. Patients experienced low need for postoperative analgesia. Free oral intake was permitted 2 h after the procedure. There were no postoperative complications, and patients were discharged, according to the study protocol, 48 h after the procedure. Conclusions Preliminary results showed the feasibility and safety of the transvaginal NOTES method in this small initial study population. The technique, developed in our institution, and not transgastric NOTES, may be the preferred approach to serve as the basis for clinical studies.     

Transvaginal endoscopic partial gastrectomy in porcine models: the role of an extra endoscope for gastric control

Background  Transvaginal natural orifice translumenal endoscopic surgery (NOTES) gastrectomy is technically challenging, because wide perigastric dissection under appropriate tissue triangulation is unfeasible with current endoscopic instruments alone. The aim of this study was to investigate the feasibility of transvaginal NOTES gastrectomy with the use of an extra endoscope as a retracting device of the stomach. Methods  This acute in vivo feasibility study was performed under the approval of the Institutional Animal Care and Use Committee (IACUC). Four female 40-kg pigs received general anesthesia and underwent transvaginal endoscopic partial gastrectomy. Under laparoscopic guidance, the uterus was fixed anteriorly and transvaginal access was established in a standard fashion. The perigastric ligaments were dissected with needle knife/insulation-tipped electrosurgical knife (IT) via transvaginally placed double-channel endoscope. This step was assisted with the second, CO₂-insufflating endoscope advanced in the stomach (i.e., so-called endoscopic gastric control). A linear stapling device with a flexible shaft was then passed transvaginally, and the anterior gastric wall was partially resected. The specimen was isolated and retrieved through the vagina. Concluding endoscopy was carried out to confirm the absence of mucosal damage due to endoscopic gastric control. This was further confirmed at necropsy immediately after sacrifice. Results  All animals underwent successful transvaginal NOTES gastrectomy. Endoscopic gastric control greatly facilitated perigastric dissection by providing appropriate tissue countertraction on the ligaments. Use of transabdominal (laparoscopic) graspers was thus minimized. There were no intraoperative complications directly related to use of the primary (transvaginal) endoscope or the additional (gastric) endoscope. Distention of downstream bowel after gastric insufflation was minimal with CO₂. No major injuries were noted on gastric mucosa at postmortem investigations. Conclusions  Transvaginal NOTES partial gastrectomy is feasible in porcine models. Use of an extra endoscope to retract the stomach is effective to minimize transabdominal assistance. Further studies on human subjects are necessary to establish this as a safe and attractive ancillary technique in NOTES.     

Hybrid transvaginal cholecystectomy, NOTES, and minilaparoscopy: analysis of a prospective clinical series

Introduction  Natural orifice transluminal endoscopic surgery (NOTES) makes it possible to perform intraperitoneal surgical procedures with a minimal number of access points in the abdominal wall. It is not yet possible to perform these interventions without the help of abdominal wall entryways, so these procedures are hybrids, a fusion of minilaparoscopy and transluminal endoscopic surgery. In this paper we present a prospective clinical series of 15 patients who underwent transvaginal hybrid cholecystectomy for cholelithiasis. Methods  This was a prospective clinical series of 15 consecutive female patients, nonrandomly chosen and without a control group, who underwent a fusion transvaginal NOTES and minilaparoscopy procedure with two entryways for cholelithiasis. One was umbilical and measured 5 mm in diameter, and the other was in the right upper quadrant and measured 3 mm in diameter. Results  The scheduled surgical intervention was performed on the 15 patients in whom it had been indicated. There were no intraoperative complications. One patient had mild hematuria that resolved in less than 12 h; there were no other complications after average follow-up of 124 days. Nine patients were discharged in 24 h, and two were discharged less than 12 h after the procedure. Discussion  Hybrid transvaginal cholecystectomy is a good surgical model for minimally invasive surgery, a combination of NOTES and minilaparoscopy. It can be performed in surgical settings where laparoscopy is practised regularly, using the instruments normally used for endoscopy and laparoscopic surgery. Owing to the reproducibility of the intervention and the ease of vaginal closure, hybrid transvaginal cholecystectomy will permit further development of NOTES in the future.     

NOTES über den transvaginalen Zugang

NOTES (?natural orifice transluminal endoscopic surgery“) has the potential to optimize minimally invasive surgery. In gynecology there is extensive experience with the transvaginal approach to the abdominal cavity. It is easy to perform, closure is safe and there is little risk of infection. Hence, this is the approach most suitable for NOTES. By means of rigid laparoscopic instruments cholecystectomy can be routinely performed. Such operations could be performed in 149 patients in our hospital and the NOTES register of the DGAV has data on more than 900 transvaginal operations.     

Pure natural orifice transluminal endoscopic surgery (NOTES) cholecystectomy

Enthusiasm for natural orifice transluminal endoscopic surgery (NOTES) has been partly tempered by the reality that most NOTES procedures to date have been laparoscopically assisted. After safely performing transvaginal cholecystectomy in an IACUC-approved porcine model, the authors embarked on an institution review board (IRB)-approved protocol for ultimate performance of pure NOTES cholecystectomy in humans. They describe their experience performing a true NOTES transvaginal cholecystectomy after safely accomplishing three laparoscopically assisted or hybrid procedures in humans. One of the patients was a 35-year-old woman presenting with symptoms of biliary colic. Ultrasound confirmed gallstones, and her liver enzymes were normal. Pneumoperitoneum to 15 mmHg was obtained via a transvaginal trocar placed through a colpotomy made under direct vision. A double-channel endoscope then was advanced into the abdomen. To overcome the retracting limitations of currently available endoscopes, the authors used an extra-long 5-mm articulating retractor placed into the abdomen via a separate colpotomy made under direct vision using the flexible endoscope in a retroflexed position. Endoscopically placed clips were used for control of both the cystic duct and the artery. These techniques obviated the need for any transabdominally placed instruments or needles. This patient was the first to undergo a completely NOTES cholecystectomy at the authors’ institution, and to their knowledge, in the United States. She was discharged on the day of surgery and at this writing has not experienced any complication after 1 month of follow-up evaluation. Performance of NOTES transvaginal cholecystectomy without aid of laparoscopic or needleoscopic instruments is feasible and safe for humans. Additional experience with this technique are required before studies comparing it with standard laparoscopy and hybrid techniques are appropriate.     

Hybrid transvaginal nephrectomy

This case study reports one case of transvaginal natural orifice transluminal endoscopic surgery (NOTES) in a 23-yr-old woman with right flank pain and recurrent urinary tract infection due to a nonfunctional right kidney. She underwent nephrectomy by transvaginal NOTES using the endoscope by vaginal access and two additional 5-mm trocars in the abdomen. Total procedure time was 170 min and estimated blood loss was 350 cc. The patient had an uneventful postoperative course and was discharged 12h after the procedure.     

Surgery without scars: report of transluminal cholecystectomy in a human being

HYPOTHESIS: Natural orifice transluminal endoscopic surgery (NOTES) provides the potential for performance of incisionless operations. This would break the physical barrier between bodily trauma and surgery, representing an epical revolution in surgery. Our group at IRCAD-EITS (Institut de Recherche contre les Cancers de l'Appareil Digestif [Institute of Digestive Cancer Research]-European Institute of TeleSurgery) has been actively involved in the development of NOTES since 2004 with a dedicated project created to develop feasibility and survival studies and new endoscopic technology. DESIGN: NOTES cholecystectomy in a woman via a transvaginal approach. SETTING: University hospital. Patient The patient was a 30-year-old woman with symptomatic cholelithiasis. INTERVENTION: The procedure was carried out by a multidisciplinary team using a standard double-channel flexible videogastroscope and standard endoscopic instruments. The placement of a 2-mm needle port, mandatory to insufflate carbon dioxide and to monitor the pneumoperitoneum, was helpful for further retraction of the gallbladder. At no stage of the procedure was there need for laparoscopic assistance. All of the principles of cholecystectomy were strictly adhered to. RESULTS: The postoperative course was uneventful. The patient had no postoperative pain and no scars, and was discharged on the second postoperative day. CONCLUSIONS: Transluminal surgery is feasible and safe. NOTES, a radical shift in the practice and philosophy of interventional treatment, is becoming established and is enormously advantageous to the patient. With its invisible mending and tremendous potential, NOTES might be the next surgical evolution.     

NOTES cholecystectomy: matched-pair analysis comparing the transvaginal hybrid and conventional laparoscopic techniques in a series of 216 patients

Background  

Natural orifice transluminal endoscopic surgery (NOTES) is currently a very important topic for both gastroenterologists and surgeons. We have developed a technique of transvaginal hybrid NOTES cholecystectomy (TVC) that leaves no visible scar and is applicable to daily use. This technique is compared to the conventional laparoscopic cholecystectomy (CLC) in a matched-pair analysis.
