Natural orifice surgery has been used with increasing frequency in colon surgeries since the early 2000's. Our aim was to examine the patients retrospectively who underwent Natural Orifice Specimen Excision (NOSE) following laparoscopic colorectal resection. A total of 102 patients 2013 and 2018 were evaluated. The demographic characteristics, intra-operative and post-operative findings, pathology results, pain, incontinence, sexual dysfunction and cosmetic scores were examined. Mean age was 57.0 ± 14 and 52 of them (51%) were female. Specimen extraction was transanal in 72 (70%) (eventration technique in 10 patients) and transvaginal in the remaining 30 patients. The mean operating time was 272 ± 108 (median 240, range 120–540) minutes, and the mean blood loss was 92 ± 87 ml (median 54, range 5–400). The mean hospital stay was 7.0 ± 4.7 days (median 6, range 3–30). The main pain scores (visual analog score) on days 1-2-3 were 3.9 ± 2.0 (median 4, range 1–9), 3.1 ± 1.7 (median 3, range 0–8), 1.9 ± 1.5 (median 1.5, range 0–7), respectively. The mean cosmetic scores were 9.1 ± 1.5 (median 10, range 3–10). The median Wexner Incontinence score was 0 (0–9). Hospital mortality was 1% and unrelated with the NOSE. The 5-year overall survival and disease-free survival rates for cancer patients were 77.2–63.3%, respectively. NOSE has advantages in laparoscopic colorectal resections. It increases patient comfort and decreases incision related complications. Clinical trials: www.clinicaltrials.gov (NCT04394988). [ABSTRACT FROM AUTHOR]

Aim This study aimed to compare the surgical outcomes of laparoscopic hysterectomy (LH) and vaginally assisted natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy procedures in women with undescended-enlarged uteri. Materials and methods This cross-sectional study was conducted with 78 women who underwent LH (48 patients) or vNOTES hysterectomy (30 patients) for benign gynecological pathologies. The dimension of the uterus, operation time, intraoperative blood loss, the presence of peri-, postoperative complications, conversion to laparotomy, pre-, postoperative hemoglobin (Hb), and hematocrit (Hct) levels, postoperative hospital stay, total dose of postoperative analgesics, VAS scores at the postoperative 6th and 24th hours, and the final pathology reports were recorded. Results There was no significant difference between LH and vNOTES hysterectomy groups regarding age (47 vs. 47.5 years, p = 0.92), parity (2 vs. 2, p = 0.74), and BMI (30.8 vs. 28.2 kg/m2, p = 0.31). The patients in the vNOTES hysterectomy group had significantly shorter durations of surgery (45 vs. 160 min) and hospitalization (48 vs. 72 h) than the LH group (p

Aim This study aimed to compare the surgical outcomes of total laparoscopic hysterectomy (TLH) and vaginally assisted natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy procedures in obese patients. Materials and methods This cross-sectional study was conducted with 83 obese women (BMI > 30 kg/m2) who underwent TLH (35 patients) or vNOTES hysterectomy (48 patients) for benign gynecological indications. The duration of surgery, intra/postoperative complications, intra- and postoperative hemoglobin (Hb) and hematocrit (Hct) levels, hospital stay, Visual analogue scale (VAS) scores at the postoperative 6th and 24th hours of the patients were compared. Results There was no significant difference between TLH and vNOTES groups regarding age (49 vs. 52 years, p = 0.35), parity (2 vs. 3, p = 0.17), and uterine weight (290 vs. 230 g., p = 0.13) The median BMI was 31.6 kg/m2 (30–42.2 kg/m2) in the TLH group and 31.9 kg/m2 (30–54.6 kg/m2) in the vNOTES group (p = 0.31). The vNOTES hysterectomy group had significantly shorter durations of surgery (67.5 vs. 136 min) and postoperative hospitalization than the TLH group (p

Aim To compare the results of conventional laparoscopic (CL) and vaginal natural orifice transluminal endoscopic surgery (vNOTES) techniques for the treatment of benign adnexal pathologies. Materials and methods The study consisted of 114 patients who underwent CL or vNOTES for oophorectomy, ovarian cystectomy, or ectopic pregnancies. The medical and surgical data of the study population in terms of age, gravidity, parity, body mass index (BMI), duration of surgery, size of the mass, decrease in hemoglobin/hematocrit levels, the presence of complications, and visual analogue scale (VAS) pain scores at the 6th and 24th hours were analyzed. Results Both groups of patients (CL and vNOTES) had a similar mean age (42.22 ± 12.05 vs. 42.38 ± 13.06), mean BMI (27.51 ± 4.96 kg/m2 vs. 29.63 ± 7.86 kg/m2), and mean mass size (53.17 ± 24.41 vs. 48.93 ± 32.33) (the p-value was nonsignificant for all comparisons). According to the logistic regression propensity score match model, the duration of surgery was significantly shorter in the vNOTES group (48.33 ± 33.12 min) compared to the CL group (72.23 ± 43.63 min) (p = .04). Postoperative hospital stay was significantly shorter in the vNOTES group (38.4 ± 14.91 hours) compared to the CL group (48 ± 17.82 hours) (p = .03). Postoperative 6th- and 24th-hour VAS pain scores were significantly lower in the vNOTES group (p = .003 and .03, respectively). Conclusion As an alternative to CL, vNOTES seems to be a promising approach for the treatment of a variety of adnexal pathologies.

Vaginal natural orifice transluminal endoscopic surgery (vNOTES) has emerged as a minimally invasive approach. This study aimed to evaluate the feasibility and surgical outcomes of the vNOTES method and compare it with conventional laparoscopy (CL) in gynecological emergency cases. A retrospective study was conducted to compare vNOTES with CL regarding pre-/intra-/postoperative outcomes. The women who were operated on for emergency indications such as ectopic pregnancy, ovarian torsion, ovarian cyst rupture and acute abdominal pain were evaluated. Patients' age, gravidity, parity, medical/surgical history, height, weight, blood pressure, heart rate, pre-/postoperative hemoglobin and hematocrit levels, the quantity of aspirated hemoperitoneum, visual analog scale (VAS) pain scores six and 12 h postoperatively, duration of surgery and hospital stay were recorded. The study was conducted with 90 women. Sixty of them underwent CL, while 30 women had vNOTES. The vNOTES group had a significantly shorter duration of surgery −28.5 min (15–48 min) vs. 77 min (29–155 min), respectively, p <.001), shorter hospital stay − 32 h (11–125 h) vs. 38 h (12–201 h), respectively, p =.007), lower VAS scores after 6 h – 5 (4–7) vs. 6 (2–8), respectively, p <.001), and after 12 h − 2 (1–3) vs. 2 (1–5), respectively, p <.001) and a lower dose of postoperative analgesic administration − 2 (2–3) vs. 3 (1–5), respectively, p <.001) than the CL group. vNOTES surgeries can be considered an alternative technique to CL by providing shorter surgery duration, lower postoperative pain scores, shorter hospital stays and better cosmetic outcomes.

The patients in the vNOTES hysterectomy group had significantly shorter durations of surgery (45 vs. 160 min) and hospitalization (48 vs. 72 h) than the LH group (p < 0.001, p < 0.001, respectively). The 24th hour VAS score was lower (VAS score 2 vs. 3, p = 0.003) in favor of the vNOTES hysterectomy group. In matched group analysis, the 24th hour VAS score (2 vs. 3, p = 0.008), operation time (45 vs. 157, p < 0.001), and hospitalization (48 vs. 72, p < 0.001) were lower in the vNOTES hysterectomy group than the LH group. vNOTES hysterectomy provides favorable outcomes compared to conventional LH considering the shorter operation time, hospitalization, and lower 24th h VAS score.

The vNOTES hysterectomy group had significantly shorter durations of surgery (67.5 vs. 136 min) and postoperative hospitalization than the TLH group (p < 0.05 for all comparisons). Besides, the 6th-hour (6 vs. 7, p = 0.02) and 24th-hour (4 vs. 3, p < 0.001) VAS scores were significantly lower in the vNOTES hysterectomy group. The propensity-matched group analysis showed significantly lower 6th-hour and 24th-hour VAS scores and shorter duration of surgery (80 vs. 135 min, p < 0.001) in the vNOTES hysterectomy group than the TLH group. vNOTES is a feasible technique in obese women who require a hysterectomy and provides favorable outcomes considering the shorter duration of surgery and postoperative hospitalization and lower pain scores.

Background: The EndoLuminal Surgical System (ELS) is an emerging non-linear robotic system specifically designed for transanal surgery that allows for excision of colorectal neoplasia and luminal defect closure. Methods: An evaluation of ELS was conducted by a single surgeon in a preclinical setting at the EndoSurgical Center of Florida in Orlando, between October 1st, 2020 and December 31st, 2020, using porcine colon as a model. Mock lesions measured 2.5 to 3.5 cm were excised partial-thickness. Specimen quality and excision time was assessed and evaluated. Results: Twenty consecutive robotic transanal minimally invasive surgery (TAMIS) operations utilizing the ELS system were successfully performed without fragmentation. The mean and standard deviation procedure time for all 20 cases was 18.41 ± 14.15 min. The latter 10 cases were completed in substantially less time, suggesting that ELS requires at least 10 preclinical cases for a surgeon to become familiar with the technology. A second task, namely suture closure of the partial-thickness defect, was performed in 9 of the 20 cases. Mean time and standard deviation for this task measured 27.89 ± 10.07 min. There were no adverse events. Conclusions: ELS was successful in performing the tasks of partial-thickness disc excision and closure in a preclinical evaluation. Further study is necessary to determine its clinical applicability. [ABSTRACT FROM AUTHOR]

We aimed to describe the initial experience of mini-laparoscopic adrenalectomy combined with transgastric specimen extraction and to assess its safety and feasibility. We used only 5-mm trocars, three ports for left adrenalectomy and four for right. Intraoperative gastroscopy was performed for specimen extraction through the mouth via an endoscopic snare. The gastrotomy was closed intracorporeally. Demographic, perioperative and pathological data were analyzed. There were 16 patients (12 females) with the mean age of 46.5 ± 11.3 years and half of them had previous abdominal surgeries. The median operative time was 150 (45–432) min with a median blood loss of 88 (0–350) ml. The median oral intake time was 2 (1–4) days and the median length of hospital stay was 2 (2–5) days. There was no mortality and extraction-related complication. Histopathological median tumor length, width and depth were 3 cm, 2.15 cm, and 1.9 cm, respectively. The median specimen length, width and depth were 6.25 cm, 4 cm, and 2.2 cm, respectively. Mini-laparoscopic adrenalectomy combined with transgastric specimen extraction is a safe and feasible surgical technique. It provides a less invasive surgery and may also have some benefits on wound-related complications and cosmesis. [ABSTRACT FROM AUTHOR]

Background: Percutaneous endoscopic gastrostomy (PEG) tube placement is one of the most common methods for establishing durable enteral access. Early PEG dislodgement occurs in < 5% of cases but typically prompts urgent surgical intervention to reestablish the gastrocutaneous tract and prevent intra-abdominal sepsis. To date, there is a single case report in the literature where successful endoscopic "rescue" of an early dislodged PEG tube negated the need for operative intervention. Here, we report our experience with a series of endoscopic PEG rescues for early dislodged PEG tubes. Methods: A retrospective analysis of cases was reviewed from two institutions. Patients with early PEG dislodgements underwent PEG rescue using a gastroscope and standard Ponsky "Pull" PEG techniques through the original tract. Results: Eleven patients were identified from the database and underwent PEG rescue after early PEG dislodgement. Mean operative time was 68 min, and there were no complications related to PEG rescue. PEG rescue permitted safe re-establishment of the gastrostomy tract while avoiding laparoscopic or open surgical intervention in hemodynamically stable patients. All patients tolerated the procedure well and were able to resume use of the PEG tubes shortly after intervention. Conclusion: Endoscopic rescue represents a feasible noninvasive option for PEG tube replacement following early inadvertent PEG tube dislodgement in appropriate clinical settings.

Hysterectomy is one of the most frequent gynaecological procedures performed for various uterine pathologies. There are several approaches for conducting hysterectomies, including abdominal, vaginal, laparoscopic and robotic. Recently, natural orifices transluminal endoscopic surgery (NOTES) has emerged as an alternative approach for conducting hysterectomies. In this study, we aimed to compare the results of total laparoscopic hysterectomy (TLH) and vaginally assisted-NOTES (vNOTES) hysterectomy procedures for the treatment of benign gynaecological diseases. Ninety-nine patients, who underwent conventional TLH or vNOTES hysterectomies, were included in this study. The operation time, presence of per/postoperative complications, visual analogue scale (VAS) scores at postoperative sixth and 24th hours, and the duration of hospital stays were all analysed. The duration of surgery was significantly shorter in the vNOTES hysterectomy group (79.56 ± 32.54 min) compared to the TLH group (120.67 ± 38.35 min) (p: < .001). Also, postoperative hospital stays were significantly shorter in favour of the vNOTES hysterectomy group (44 ± 16.47 h) compared to the TLH group (57.86 ± 21.31 h) (p: .002). These results indicate that vNOTES hysterectomy can be a promising approach for treating a variety of different uterine pathologies and, furthermore, that it can be an alternative to TLH.Impact statementWhat is already known on this subject? A hysterectomy can be done in a variety of different ways, such as abdominal, laparoscopic, vaginal, and robotic. Even though the standard practice guidelines recommend that a vaginal hysterectomy (VH) should be the first choice of treatment, it can be challenging in cases of non-descendent and large uteruses. In such cases, NOTES hysterectomy can be an alternative option.What do the results of this study add? The study has shown that vNOTES is associated with a shorter operation and briefer postoperative hospitalisation time, in comparison to TLH.What are the implications of these findings for clinical practice and/or further research? This study speculates that vNOTES is an approach which may offer better outcomes than a conventional laparoscopy. Further randomised controlled trials with larger sample sizes, however, should be conducted in order to establish the place of vNOTES in hysterectomy surgeries. [ABSTRACT FROM AUTHOR]

Risk of gastric spillage during transgastric surgery is a potential complication of NOTES procedures. The aim of this study was to determine risk outcomes from gastric spillage in a rat survival model by measuring local and systemic inflammatory markers, adhesive disease, and morbidity.We performed a minilaparotomy with needle aspiration of 2 ml of gastric contents mixed with 2 ml of sterile saline (study group, SG) or 4 ml of sterile saline (control group, CG) injected into the peritoneal cavity of 60 male rats. Inflammatory markers (TNFα, IL-6, and IL-10) were analyzed at 1, 3, 6, and 24 h postoperatively by obtaining plasma levels and peritoneal washings. At necropsy, the peritoneal cavity was examined grossly for adhesions.Adhesions were seen more frequently in the SG versus the CG (100% vs. 33.3%, p

During transgastric natural orifice transluminal endoscopic surgery (NOTES), there is an iatrogenic perforation of the gastric wall with leakage of gastric contents into the peritoneal cavity. The aim of this study is to determine the effect of proton-pump inhibitors (PPI) and alterations of gastric pH on infection during transgastric surgery.Thirty 250-g male Sprague–Dawley rats were divided into a study group (SG, n = 15) and a control group (CG, n =15). SG were given 5 mg/kg pantoprazole for 3 days before procedure and another dose 1 h before. CG received saline at similar time points. A mini-laparotomy with gastrotomy was performed. Aspiration of 2.0 cc gastric contents was removed from the stomach and injected into the peritoneal cavity of both groups. Gastric pH and peritoneal pH levels were obtained. Gastric aspirate was sent for culture. White blood cell counts (WBC) were obtained on postoperative days 1, 7, and 14, and C-reactive protein (CRP) levels were obtained on postoperative day 1. At day 14, a necropsy was performed and aerobic and anaerobic cultures of the peritoneal cavity were obtained.There were no deaths in either group. The average gastric pH in the SG was 5.13 versus 3.26 (p = 0.03) in the CG. The average peritoneal pH was similar in both groups. The WBC in the SG was 4.5 vs. 3.5 (1,000 cells/mm) in the CG. There was no elevation in CRP levels in either group. Bacterial cultures were positive in 3/15 (20%) rats in the CG and in 9/15 (60%) in the SG (p = 0.008). Intra-abdominal abscesses were found in 2/15 (13%) rats in the CG and in 5/15 (33%) in the SG (p = 0.08).Pretreatment with a PPI resulted in a higher rate of peritoneal bacterial contamination and abscess formation. The acidic environment of the stomach appears to be protective against infection when intraperitoneal contamination occurs as a result of gastrotomy.

Here, we presented a case of laparoscopic colon cancer resection who developed vaginal recurrence after transvaginal specimen extraction. To our knowledge, this is the first case report on natural orifice specimen extraction-site cancer recurrence. A 59-year-old female underwent laparoscopic left hemicolectomy due to left-sided colon adenocarcinoma, and the specimen was removed through the vagina. She was admitted to the hospital with the complaint of vaginal discharge after 1 year. Tumoural infiltration on the posterior vaginal wall was diagnosed, and biopsy was reported as adenocarcinoma. The patient underwent laparoscopic low anterior resection, total abdominal hysterectomy, bilateral salpingooferectomy and en bloc resection of the posterior vaginal wall due to the local recurrence of colon cancer. She had no recurrence or metastasis within the 3rd year after primary tumour surgery. Recurrence at the specimen extraction site after natural orifice surgery should be considered among the complications. For this reason, incision-preserving methods should not be neglected.

Numerous studies have confirmed significant benefits of intracorporeal anastomosis (ICA) following colorectal procedures; however technical challenges have limited this approach following conventional laparoscopic surgery. The robotic Xi platform serves as an enabling technology and has resulted in a surge of reports for right-sided ICA, however, there are no reports involving more complex left-sided procedures such as diverticulitis. Furthermore, there are no reports of natural orifice-assisted techniques using robotic Xi in which the specimen can be removed and the anvil can be placed transrectally, thereby completely eliminating the need for an abdominal wall incision other than for port sites. We present a pilot study to investigate the safety, feasibility and short-term outcomes of robotic Natural orifice-assisted IntraCorporeal anastomosis with transrectal Extraction of specimen, called the robotic NICE procedure. Consecutive patients presenting for elective resection for diverticulitis with formation of a colorectal anastomosis were entered into an IRB database. All patients underwent the robotic NICE procedure. Demographic data, intraoperative data and outcomes data were assessed and analyzed. Ten patients (five males and five females) underwent resection. The mean age and BMI were 56 years (43–66) and 29 kg/m2 (21–35). All procedures were successfully completed including transrectal extraction of the specimen and formation of an ICA. The mean operative time was 198 min (146–338) and mean EBL was 35 ml (15–50). Mean time to first flatus was 16 h (10–22) and mean length of stay was 1.9 days (1.6–2.6). There were no intraoperative or postoperative complications. There was no unexpected ICU stay, reoperation or readmission. Colorectal left-sided resections such as for diverticulitis were safely accomplished using natural orifice-assisted extraction of the specimen as well as complete intracorporeal anastomosis in this pilot study. The NICE procedure resulted in early return of bowel function, short length of stay and low complication. The complete elimination of abdominal wall incision likely accounts for these findings and larger cohorts of patients are to be investigated to explore this promising approach afforded by robotic technology.

Background: Natural orifice specimen extraction (NOSE)surgery is gaining popularity among colorectal surgeons. The technical aspects of this new procedure are still debated and many variations have been presented in the last decade. Methods: We propose a new variation of transanal NOSE after robotic and laparoscopic LAR consisting of rectal eversion by using a special rod after laparoscopic TME. Eversion makes it possible to perform resection and placement of the anvil extracorporeally. We included a video demonstration of the technique. Clinical Patient Grading Assessment Scale was calculated 1 month after stoma closure and the Low Anterior Resection Syndrome (LARS)score was calculated preoperatively and 1 month after stoma closure. Results: Seven female patients with rectal cancer, all with normal BMI, underwent laparoscopic (n = 5) or robotic (n = 2) TME with rectal eversion. No intraoperative and postoperative complications were reported. One month after stoma closure, the median Clinical Patient Grading Assessment Scale was 5 (range 3–7), which means "a good deal better". The median LARS score was 14 (IQR 14–19,5) preoperatively and 19 (IQR 19–21,5) 1 month after stoma closure. Conclusions: This variation of NOSE surgery was safe and effective in our patient population. [ABSTRACT FROM AUTHOR]

Introduction: Natural orifice surgery has been increasingly used in colon surgery since the early 2000s. However, it is rarely used for total colectomy. In this study, we aimed to retrospectively compare natural orifice specimen extraction (NOSE) with transabdominal specimen extraction in patients undergoing laparoscopic total colectomy.Materials and Methods: Twenty-six patients who underwent laparoscopic total colectomy between 2013 and 2017 were enrolled and the patients were divided into two groups: NOSE (n = 13) and transabdominal group (n = 13). The patients' demographic characteristics, perioperative and postoperative outcomes, pathology results, visual analog scale scores, and cosmetic scores were compared.Results: There was no significant difference between the two groups in terms of demographic characteristics as well as perioperative and postoperative outcomes, including complications. Benign pathologies were more common in the NOSE group (85% versus 15%, P = .001). The pain scores of the postoperative first, second, and third days were significantly lower in the NOSE group 4.1 ± 2.1 versus 7.1 ± 1.3 (P = .005), 3.7 ± 2.2 versus 6.0 ± 1.5 (P = .003), and 2.2 ± 2.0 versus 4.1 ± 0.9 (P = .03), respectively. As expected, the mean cosmetic score was significantly better in the NOSE group (8.3 ± 1.5 versus 6.7 ± 1.8, P = .02).Conclusion: NOSE combined with laparoscopic total colectomy provided better patient comfort in benign diseases and small-sized malignant diseases.

Aim: In minimally invasive surgery, incisions made for specimen extraction or anvil placement affect morbidity. The aim of this study was to analyze and share the experience of a single surgeon in laparoscopic colorectal surgery, specimen extraction, and anvil placement. Material and Methods: Patients who underwent laparoscopic colorectal surgery were evaluated retrospectively. Patient characteristics, operative data, specimen extraction site, and anvil placement methods were assessed. Postoperative complications, length of hospital stay, and outpatient follow-up data were analyzed. Results: A total of 27 patients were included in the study. The group included 6 females and 21 males with a mean age of 64.1±11.6 years. Mean body mass index was 28.9±5.8. Surgery was performed due to colorectal cancer in 20 patients, familial adenomatous polyposis in 3 patients, villous adenoma in 3 patients, and ulcerative colitis in 1 patient. Mean length of hospital stay was 8.8±7 days and mean follow-up time was 13.4±7.7 months. Mean operative time was 188.9±47.1 minutes and total blood loss was 67.4±46.1 mL. Additional abdominal wall incisions were made for specimen extraction in 15 patients (56%). Natural orifice specimen extraction was performed in 10 patients (37%), while the ostomy site was used for specimen extraction in 2 patients (7%). In thirteen patients (48%) the additional abdominal wall incision was used for anvil placement. Of the remaining patients, the anvil was inserted through the transanal route in 3 patients (11%), ileostomy site in 2 patients (7%), and trocar site in 1 patient (4%). An anvil was not used for 8 patients (30%). Conclusion: Specimen extraction and anvil placement in laparoscopic colorectal surgery can be achieved using different techniques, and the use of natural orifices and ostomy sites during the procedure is beneficial. Further research into this subject is needed. [ABSTRACT FROM AUTHOR]

The aim of this study was to demonstrate the feasibility of laparoscopic restorative proctocolectomy (LRPC) without additional abdominal incisions. Two sisters with familial adenomatous polyposis were enrolled. The colon and rectum were mobilized entirely through the five abdominal trocars. The terminal ileum and distal rectum were transected with endoscopic staplers. The entire colorectal specimen was extracted transanally. A circular stapler anvil was introduced transanally. The J-pouch was created intracorporeally. The rectal stump was re-closed and a pouch-anal anastomosis was created using a circular stapler. We used a transanal tube for decompression of the pouch instead of a diverting ileostomy. The patients were discharged on the 10th and 12th days uneventfully. Both were doing well with their pouches after 18.5 and 12.1 months of follow-up. With the help of transanal specimen extraction and transanal tube decompression, additional abdominal incisions can be avoided following LRPC.

Objectives: To evaluate the feasibility and safety of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) in patients 70 years and over., Material and Methods: The study consisted of eleven patients aged 70 and over who underwent vNOTES for a variety of gynaecological indications at a tertiary referral hospital. The medical and surgical data were noted: age, parity, history of comorbidity, number and type of previous surgeries, body mass index (BMI), operating time, the requirement of intraoperative conversion, the presence of intra- or postoperative complication, estimated blood loss, pre-and postoperative hemoglobin levels, visual analog scale (VAS) pain scores at 6th, 12th and 24th hours, length of hospital stay, and the final pathology results., Results: vNOTES surgery was performed safely and successfully in eleven patients. There were no intra- and postoperative complications or instances of conversions to conventional laparoscopy or laparotomy. The mean age of patients was 75.91 ± 6.47 (range 70-93), and the mean BMI was 42.49 ± 8.77 kg/m2 (range 30.2-56). Seven cases of endometrioid adenocarcinoma, two cases of uterine leiomyoma, one case of complex atypical hyperplasia, and one case of postmenopausal uterine bleeding due to atrophic endometrium were diagnosed. All endometrial carcinomas were early stage; no adjuvant therapy was needed., Conclusions: vNOTES seems to be a safe and feasible approach for the treatment of gynecologic pathologies in elderly patients. This study suggests that vNOTES become a viable treatment option for existing minimally invasive procedures since it offers better surgical outcomes in various gynecologic surgeries.

Background: Minimally invasive thyroid and parathyroid resections are rarely performed. Promising new endoscopic transoral approaches to the anterior neck (transoral endoscopic thyroidectomy vestibular approach [TOETVA]) have been described with good results and few complications. This study evaluates a new device to allow the safe entrance of trocars in the subplatysmal space for TOETVA in a cadaver model.Methods: The technique was performed in 4 unilateral thyroidectomies in female cadavers. The technical steps consisted of a 10-mm incision made at the center of the oral vestibule followed by subplatysmal hydrodissection. The blunt dissector is a metallic stick with an olive at the end and promotes progressive gain in subplatysmal space enlarging the operative field. The instrument was inserted creating a space below the platysma to the anterior neck and the strap muscles. Three trocars were inserted in the vestibular area. The dissection begins by cutting the linea alba cervicalis. The isthmus was dissected and transected. Anatomical structures as the superior thyroid artery, parathyroid glands, and the recurrent laryngeal nerve could be safely identified with magnified vision.Results: Optimal operative field due to subplatysmal dissection by the device allowed for exposition of thyroid and parathyroid glands in all cases. Unilateral thyroidectomy was performed in a mean of 54 minutes with excellent aesthetic results.Conclusions: The new device is a promising feature to allow safe transoral thyroid surgery in a cadaver model. Further studies in clinical series are needed to evaluate the broad application of the device. [ABSTRACT FROM AUTHOR]

Lingual thyroglossal duct cysts are a rare and potentially difficult to manage tongue base lesion. We report a case of transoral robotic surgical excision of a lingual thyroglossal duct cyst, in an adult patient. A 68-year-old man presented with a large base of tongue mass, with appearance on ultrasound and computed tomography consistent with a lingual thyroglossal duct cyst. We describe the surgical technique for transoral robotic excision of the cyst. The cyst was completely excised, and the patient had a smooth recovery. There has been no recurrence of the cyst. Transoral robotic surgery has several advantages over the conventional surgical approaches in the treatment of lingual thyroglossal duct cysts, including superior visualisation, and the ability of the robotic surgical system to manoeuvre instruments in a confined space. This enables complete excision, preventing recurrence of the cyst whilst also avoiding a neck scar. [ABSTRACT FROM AUTHOR]

Study Objective: To demonstrate the utility of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for opportunistic bilateral salpingectomy for permanent sterilization after a failed attempt at bilateral tubal ligation at the time of previous cesarean section.Design: Stepwise demonstration with narrated video footage.Setting: There is evidence to support the statistically significant superiority of vNOTES compared with conventional laparoscopy (CL) in terms of patient satisfaction, postoperative pain, time to recovery, and cosmetic results in bilateral salpingectomies for permanent sterilization [1]. Limited studies demonstrate the ease and safety of access to the abdominal cavity in vNOTES while avoiding passage through the abdominal wall, port site complications (infection, hernia, etc.), and those associated with peritoneal adhesions during abdominal laparoscopy or laparotomy [2]. To the best of our knowledge, this would be the first published video of a vNOTES bilateral salpingectomy performed specifically in a patient whose previously attempted bilateral tubal ligation was unsuccessful owing to adhesive disease from 4 previous cesarean sections.Interventions: Institutional review board approval was not required. We describe a case of a 31-year-old female, with a history of 4 previous cesarean deliveries and a cholecystectomy, who desired permanent sterilization 3 months after the previous cesarean section. During previous cesarean section, bilateral adnexa were unable to be accessed owing to dense adhesions from previous surgeries. The patient was counseled on various forms of reversible contraceptive methods; however, she desired permanent sterilization with a surgical procedure. She was counseled on the various routes for opportunistic salpingectomy. Risks, benefits, and alternatives of each surgical approach were discussed. The patient consented for vNOTES opportunistic salpingectomy and possible CL. She was aware that she had significant adhesive disease at the time of previous cesarean section, so may potentially require a laparotomy for the procedure. However, she refused a laparotomy if the surgery was unable to be performed minimally invasively. (1) Demonstrate setup of transvaginal access platform for vNOTES bilateral salpingectomy. (2) Abdominal survey and appreciation of severe adhesive disease through posterior cul-de-sac. (3) Bilateral salpingectomy through single-site vaginal natural orifice surgery.Conclusion: vNOTES bilateral salpingectomy can be considered as a reasonable alternative to CL in patients with severe abdominal adhesive disease from previous surgeries.

Background: Applications for natural orifice translumenal endoscopic surgery (NOTES) to access the abdominal cavity have increased in recent years. Despite potential advantages of transanal and transcolonic NOTES for colorectal pathology, it has not been widely applied in the clinical setting. This study describes a series of nine patients for whom we performed transanal retrograde ("Down-to-Up") total mesorectal excision for rectal cancer. Materials And Methods: Under IRB approval, informed consent was obtained from each patient with rectal adenocarcinoma. Rectosigmoidectomy with total mesorectal excision was performed using low rectal translumenal access to the mesorectal fascia and subsequent dissection in a retrograde fashion. This was achieved using either a single port device or flexible colonoscope with endoscopic instrumentation and laparoscopic assistance. This was followed by transanal extraction of the specimen and hand-sewn anastomosis. Results: Mean operative time was 311 min. Mean hospital stay was 7.56 days. Complications occurred in two patients, and consisted of one anastomotic leakage with reoperation and one intraoperative conversion to open surgery because of impossibility to dissect the specimen. TME specimen integrity was adequate in six patients. Conclusion: This series suggests that a retrograde mesorectal dissection via a NOTES technique is feasible in patients with rectal adenocarcinoma. This technique may act as a complimentary part of operative treatment for rectal cancer alongside other minimally invasive strategies. Long-term follow up will be needed to assess oncological results.

We present two cases of natural orifice specimen extraction (NOSE) after laparoscopic total colectomy and ileorectal anastomosis (TC-IRA), and we also review all of the previously reported cases. Our aim was to focus on patient selection for NOSE after TC-IRA. The PubMed and Google Scholar databases were scanned. Demographic features, surgical indications, and techniques were analyzed. Basic calculations were used for statistical analysis. A total of 13 cases were detected in addition to our 2 cases. All of the specimens were removed through the natural orifices successfully. No case required a diverting ileostomy. No patients were converted to open surgery or to conventional laparoscopy. Complications were reported in three patients. Transanal extractions were performed in 12 cases (10 colonic inertia, 2 polyposis), and transvaginal extractions were performed in 3 cases (2 malignancy, 1 colonic inertia). Both transanal and transvaginal specimen extractions after laparoscopic TC-IRA can be preferred. However, transanal extraction seems to be feasible in cases of TC for benign disease with a limited mesenteric-omental resection. If the indication is a malignancy requiring a mesenteric-omental resection, a transvaginal route should be preferred for a voluminous specimen. [ABSTRACT FROM AUTHOR]

Within the last 10 years there have been significant advances in minimal-access surgery. Although no emerging technology has demonstrated improved outcomes or fewer complications than standard laparoscopy, the introduction of the robotic surgical platform has significantly lowered abdominal hysterectomy rates. While operative time and cost were higher in robotic-assisted procedures when the technology was first introduced, newer studies demonstrate equivalent or improved robotic surgical efficiency with increased experience. Single-port hysterectomy has not improved postoperative pain or subjective cosmetic results. Emerging platforms with flexible, articulating instruments may increase the uptake of single-port procedures including natural orifice transluminal endoscopic cases. [ABSTRACT FROM AUTHOR]

Objectives/hypothesis: To demonstrate that reconstructive transoral laser microsurgical (R-TLM) techniques can be used for the treatment of symptomatic laryngeal posterior glottic web-based stenosis (PGWS) in a large cohort of patients utilizing a postcricoid mucosal advancement flap (PCMAF).Study Design: Retrospective cohort review.Methods: A consecutive series of patients with PGWS who underwent R-TLM using a PCMAF were reviewed for outcomes. After laser excision of the PGWS scar and mobilization of fixed cricoarytenoid joints, a PCMAF was raised using microinstruments and a scanning free-beam CO2 laser. The flap was advanced and attached over the scar bed using a technique with multiple novel features that make it easy to adopt.Results: Fifty-two patients were treated. Of the cases, 42.3% had a tracheostomy at presentation with grade II to IV PGWS, and 46% of cases had grade III to IV PGWS. In all cases, R-TLM was the only treatment approach. No open reconstructions were performed. No airway stents were used. Patients without tracheostomy, regardless of the grade of stenosis, did not require a tracheostomy to undergo this operation. All tracheostomy patients were successfully decannulated. All patients without a tracheostomy had significant improvement of their respiratory symptoms on the Dyspnea Index (mean Δ = 14.75, P value <.01).Conclusions: RTLM using the PCMAF is a feasible, safe, and effective alternative to open approaches for airway reconstruction for PGWS. This novel transoral technique includes a much simpler endoscopic suturing alternative to knot tying among other new features. It is reproducible and reliable for laryngologists familiar with laryngeal microsurgery.Level Of Evidence: 4. Laryngoscope, 127:685-690, 2017. [ABSTRACT FROM AUTHOR]

The goal of this study was to establish face, content, and construct validity of NOViSE-the first force-feedback enabled virtual reality (VR) simulator for natural orifice transluminal endoscopic surgery (NOTES). Fourteen surgeons and surgical trainees performed 3 simulated hybrid transgastric cholecystectomies using a flexible endoscope on NOViSE. Four of them were classified as "NOTES experts" who had independently performed 10 or more simulated or human NOTES procedures. Seven participants were classified as "Novices" and 3 as "Gastroenterologists" with no or minimal NOTES experience. A standardized 5-point Likert-type scale questionnaire was administered to assess the face and content validity. NOViSE showed good overall face and content validity. In 14 out of 15 statements pertaining to face validity (graphical appearance, endoscope and tissue behavior, overall realism), ≥50% of responses were "agree" or "strongly agree." In terms of content validity, 85.7% of participants agreed or strongly agreed that NOViSE is a useful training tool for NOTES and 71.4% that they would recommend it to others. Construct validity was established by comparing a number of performance metrics such as task completion times, path lengths, applied forces, and so on. NOViSE demonstrated early signs of construct validity. Experts were faster and used a shorter endoscopic path length than novices in all but one task. The results indicate that NOViSE authentically recreates a transgastric hybrid cholecystectomy and sets promising foundations for the further development of a VR training curriculum for NOTES without compromising patient safety or requiring expensive animal facilities.

Here, we presented a case of laparoscopic colon cancer resection who developed vaginal recurrence after transvaginal specimen extraction. To our knowledge, this is the first case report on natural orifice specimen extraction-site cancer recurrence. A 59-year-old female underwent laparoscopic left hemicolectomy due to left-sided colon adenocarcinoma, and the specimen was removed through the vagina. She was admitted to the hospital with the complaint of vaginal discharge after 1 year. Tumoural infiltration on the posterior vaginal wall was diagnosed, and biopsy was reported as adenocarcinoma. The patient underwent laparoscopic low anterior resection, total abdominal hysterectomy, bilateral salpingooferectomy and en bloc resection of the posterior vaginal wall due to the local recurrence of colon cancer. She had no recurrence or metastasis within the 3rd year after primary tumour surgery. Recurrence at the specimen extraction site after natural orifice surgery should be considered among the complications. For this reason, incision-preserving methods should not be neglected.
