IRANIAN JOURNAL OF MEDICAL SCIENCES 2015; 40:425-9. [PMID: 26379349 PMCID: PMC4567602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/06/2014] [Revised: 03/26/2014] [Accepted: 04/28/2014] [Indexed: 10/31/2022]
Abstract
BACKGROUND The natural orifice transluminal endoscopic surgery (NOTES) has become a commonly considered novel approach in the surgical field. The NOTES provide possibility of operation through the natural orifice and decreases the intentional puncture of the systemic organ and subsequent complications. Totally transanal laparo-endoscopic single-site proctoColectomy-Ileoanal J-Pouch (TLPC-J) is a novel method in minimally invasive surgery for total colectomy. The main goal of this study is to perform this new method on an animal model, to assess probable complication and to resolve probable issues by using patients that are candidate for total colectomy. METHOD Five dogs were prepared in lithotomy position. The TLPC-I procedure consists of endorectal technique with full thickness rectal dissection starting 1 cm orally from the dentate line above the peritoneal reflection and the proximal bowel was replaced into the abdominal cavity. Afterwards, the TriPort system was inserted in the anal canal and mesentrial resection of the total colon, mobilization of a distal ileal segment and intracorporeal suture of an ileal J-loop was accomplished by this system. An incision in the J-loop was conducted transanally. The J-pouch was created with an Endo-GIA® and sutured to the rectal wall. RESULTS All animals survived and passed stool with clear post operation situation. There was no infection in site of anastomosis. CONCLUSION The TLPC-I provides the possibility of surgery without abdominal wall incision and decreases post operation complication such as pain, abdominal wound infection and wound dehiscence. This technique increases the quality of life and surgeons can discharge the patients early.

Abstract
Laparoscopic access in low anterior rectal resection is widely adopted, performing an 'up-to-down' dissection. The aim of this study is to present and analyze the outcomes of a novel surgical 'down-to-up' total mesorectal excision technique that could obviate to the well-known issues of the standard treatment. 18 suitable patients underwent double endolaparoscopic pelvic access (DEPA) 'down-to-up' technique. DEPA TME was completed in all patients, with intact mesorectum. Mean operative time was 365 min (range 280-510 min). The morbidity rate was 22%, including three radiologically detected leakage (grade A) and one pelvic abscess, requiring only a conservative management. Mortality rate at 30 and 90 days was 0%. Resection margins were negative in all patients. A median of 11 nodes (range 5-19) was retrieved per specimen. Mean length of hospital stay was 9 days (range 7-19 days). Patients were followed for an average of 14 months (range 0-42 months), with no recurrence. Despite exiguous patient's sample in this pilot study, transanal endoscopic TME with laparoscopic assistance seems to be feasible and safe, and is a promising alternative to open and laparoscopic TME. However, a conspicuous functional and oncologic long-term evaluation is required, before the widespread adoption could be recommended.

Abstract
Single-incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES) have rapidly gained pace worldwide, potentially replacing conventional laparoscopic surgery (CLS) as the preferred colorectal surgery technique. Currently available data mainly consist of retrospective series analyzed in four meta-analyses. Despite conflicting results and lack of an objective comparison, SILS appears to offer cosmetic advantages over CLS. However, due to conflicting results and marked heterogeneity, present data fail to show significant differences in terms of operative time, postoperative morbidity profiles, port-site complications rates, oncological appropriateness, duration of hospitalization or cost when comparing SILS with conventional laparoscopy for colorectal procedures. The application of “pure” NOTES in humans remains limited to case reports because of unresolved issues concerning the ideal access site, distant organ reach, spatial orientation and viscera closure. Alternatively, minilaparoscopy-assisted natural orifice surgery techniques are being developed. The transanal “down-to-up” total mesorectum excision has been derived for transanal endoscopic microsurgery (TEM) and represents the most encouraging NOTES-derived technique. Preliminary experiences demonstrate good oncological and functional short-term outcomes. Large-scale randomized controlled trials are now mandatory to confirm the long-term SILS results and validate transanal TEM for the application of NOTES in humans.

Abstract
Flexible endoscopy is increasingly developing into a therapeutic instead of a purely diagnostic discipline. Improved visualization makes early lesions easily detectable and allows us to decide ad hoc on the required treatment. Deep enteroscopy allows the exploration of even the small bowel - for long a "white spot" for gastrointestinal endoscopy - and to perform direct treatment. Endoscopic submucosal dissection is a considerable step forward in oncologically correct endoscopic treatment of (early) malignant lesions. Though still technically challenging, it is increasingly facilitated by new manipulation techniques and tools that are being steadily optimized. Closure of wall defects and hemostasis could be improved significantly. Even the anatomy beyond the gastrointestinal wall is being explored by the therapeutic use of endoluminal ultrasound. Endosonographic-guided surgery is not only a suitable fallback solution if conventional endoscopic retrograde cholangiopancreatography fails, but even makes necrosectomy procedures, abscess drainage, and neurolysis feasible for the endoscopist. Newly developed endoscopic approaches aim at formerly distinctive surgical domains like gastroesophageal reflux disease, appendicitis, and cholecystitis. Combined endoscopic/laparoscopic interventional techniques could become the harbingers of natural orifice transluminal endoscopic surgery, whereas pure natural orifice transluminal endoscopic surgery is currently still in its beginnings.

On the suitability of Thiel cadavers for natural orifice transluminal endoscopic surgery (NOTES): surgical training, feasibility studies, and anatomical education. Surg Endosc 2014; 29:737-46. [PMID: 25060684 DOI: 10.1007/s00464-014-3734-0] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2013] [Accepted: 07/07/2014] [Indexed: 12/15/2022]
Abstract
BACKGROUND Surgical training in virtual, animal and cadaver models is essential for minimally invasive surgery. Thiel cadavers are suitable for laparoscopy, but there are few data about the use of embalmed (Tutsch method) and slightly embalmed (Thiel method) cadavers in procedures of Natural Orifice Transluminal Endoscopic Surgery (NOTES), which are usually developed and learned on swine models and fresh frozen cadavers. The aim of this study was thus to assess the use of these cadavers for NOTES approaches. METHODS The following surgical procedures were evaluated: transanal total mesorectal excision (four cadavers: one Tutsch, two Thiel, one fresh frozen), transanal ileorectal bypass (five cadavers: one Tutsch, three Thiel, one fresh frozen), and transvaginal appendectomy (two Tutsch cadaver). RESULTS The Thiel method ensured tissue flexibility and consistency suitable for performing the above surgical procedures with good results and without complications, with only a small increase in rigidity with respect to fresh specimens. Cadavers embalmed with higher formalin concentrations (Tutsch method) were more difficult to use, due to high tissue rigidity and resistance of the abdominal wall to pneumoperitoneum, although NOTES accesses were possible. CONCLUSIONS Thiel cadavers are suitable for transanal/transrectal and transvaginal NOTES approaches, for training surgical residents/specialists and also for surgical research. In minimally invasive surgery (and particularly in NOTES), integration between cadaver (fresh frozen and/or Thiel) and animal models would represent the gold standard, allowing guaranteed knowledge of and respect for human surgical anatomy and correct management of surgery on living subjects. NOTES approaches to human cadavers may also be proposed for the anatomical education of medical students.

Abstract
OBJECTIVE To assess the feasibility of robotic transrectal hybrid natural orifice translumenal endoscopic surgery (NOTES) nephrectomy and adrenalectomy. MATERIALS AND METHODS A male cadaver was used for the present investigation and placed in lithotomy position. An 8- and 12-mm port was inserted through the same periumbilical skin incision. An incision was then created in the rectum 1 cm above the pectinate line, and a submucosal tunnel was developed, through which a robotic 8-mm port was inserted under vision. The cadaver was then placed in the right side up, flank position. The laparoscope and the right robot instrument were introduced through the umbilicus while the left robot instrument was introduced through the rectal port aiding the peri-umbilical ports in kidney and adrenal dissection. After completion of the nephrectomy, the kidney was placed in a specimen bag and extracted intact through the rectum. Closure of the rectal incision was accomplished extracorporeally using 2 suture layers. RESULTS Robotic transrectal hybrid NOTES nephrectomy and adrenalectomy were completed successfully. The total operative time was 145 minutes, of which the access and robotic docking required 20 minutes. Kidney dissection and hilar control was achieved within 60 minutes. Right adrenalectomy, specimen extraction, and rectal closure was completed in 15, 30, and 20 minutes, respectively. CONCLUSION We report the first investigation of a robot-assisted transrectal hybrid NOTES nephrectomy and adrenalectomy in a cadaver model to assess the range of motion and articulation of the robotic platform. Additional investigations in live animal model are needed to evaluate the safety of the transrectal approach.

Abstract
BACKGROUND Randomized clinical trials (RCTs) have shown multiport laparoscopic surgery to be safe compared with open surgery in elective colonic disease. Single-incision laparoscopic surgery (SILS) represents the latest advance in laparoscopic surgery. The aim of this systematic review was to establish the safety and complication profile of colonic SILS. METHODS The search was performed in October 2011 using PubMed, MEDLINE, Embase and the Cochrane Central Register of Controlled Trials. Search terms were 'colorectal', 'colon', 'colectomy', 'rectal' and single incision/port/trocar/site/scar. Only pure single-incision laparoscopic colonic surgery for benign and malignant colonic disease was included. Primary outcomes were the early postoperative complication profiles of colonic SILS. Secondary outcomes were duration of operation, lymph node yields, conversion rate and duration of hospital stay. RESULTS Colonic SILS data were compared with data from a Cochrane review on the short-term outcomes of laparoscopic colonic surgery and four main RCTs on laparoscopic colonic surgery. Median operating times and time to first bowel motion for colonic SILS were comparable with those for laparoscopic colonic surgery. The median lymph node retrieval for malignant disease achieved with SILS was acceptable. Evidence for a reduction in postoperative pain with SILS was conflicting. There was no significant reduction in length of hospital stay with SILS. Most patients selected for colonic SILS had a low body mass index, non-bulky tumours and were operated on by experienced laparoscopic surgeons. There was significant heterogeneity in study group characteristics, indications for surgery, research methodology, operative techniques and follow-up time. CONCLUSION Colonic SILS should be restricted to highly selected patients; operations should be performed by experienced laparoscopic surgeons, with critical appraisal of clinical outcomes.
