    ABSTRACT: Patient benefits from natural orifice transluminal endoscopic surgery (NOTES) are of interest in acute-care surgery. This review provides an overview of the historical development of NOTES procedures, and addresses their current uses and limitations for intra-abdominal emergency conditions. A PubMed search was carried out for articles describing NOTES approaches for appendicectomy, percutaneous gastrostomy, hollow viscus perforation and pancreatic necrosectomy. Pertinent articles were reviewed and data on available outcomes synthesized. Emergency conditions in surgery tax the patient's cardiovascular and respiratory systems, and fluid and electrolyte balance. The operative intervention itself leads to an inflammatory response and blood loss, thus adding to the physiological stress. NOTES provides a minimally invasive alternative access to the peritoneal cavity, avoiding abdominal wall incisions. A clear advantage to the patient is evident with the implementation of an endoscopic approach to deal with inadvertently displaced percutaneous endoscopic gastrostomy tubes and perforated gastroduodenal ulcer. The NOTES approach appears less invasive for patients with infected pancreatic necrosis, in whom it allows surgical debridement and avoidance of open necrosectomy. Transvaginal appendicectomy is the second most frequently performed NOTES procedure after cholecystectomy. The NOTES concept has provided a change in perspective for intramural and transmural endoscopic approaches to iatrogenic perforations during endoscopy. NOTES approaches have been implemented in clinical practice over the past decade. Selected techniques offer reduced invasiveness for patients with intra-abdominal emergencies, and may improve outcomes. Steady future development and adoption of NOTES are likely to follow as technology improves and surgeons become comfortable with the approaches.

    ABSTRACT: Staging peritoneoscopy is typically done by laparoscopy in the operating room. Natural orifice transluminal endoscopic surgery peritoneoscopy is an appealing alternative to the current approach. Transcolonic submucosal endoscopy with mucosal flap (SEMF) may provide natural orifice transluminal endoscopic surgery peritoneoscopy. The aim was to verify the feasibility and safety of transcolonic peritoneoscopy with SEMF (TCPS) in a porcine survival model. Survival study. Animal research unit. Seven target beads were placed in the peritoneal cavity by laparoscopy in each of 6 animals, and TCPS was performed to identify and touch beads to simulate biopsy. Animals were euthanized after 1 week, at which time, laparotomy was performed and the SEMF site was resected for histological analysis. The number of beads identified and touched during peritoneoscopy, rate of successful completion of TCPS, procedure time, mortality equivalent 1 week after TCPS, adverse event rate, histological assessment of SEMF site. All 7 beads in all 6 pigs were identified and touched during TCPS. The success rate of TCP was 100%. No major adverse events occurred during the procedure. The median procedure times for the creation of a submucosal tunnel, peritoneoscopy, closure of mucosal incision, and entire procedure were 19.5, 17, 9.5, and 45 minutes, respectively. All pigs survived until euthanasia, and there was no evidence of peritonitis or severe infection. Animal study, single endoscopist, small sample size. Results of this study indicate that TCPS is feasible and safe in a porcine survival model.

    ABSTRACT: Aim: Patients prefer minimally invasive procedures with fast recovery, minimal pain and good cosmesis. Single-port cholecystectomy may decrease the need for narcotic pain medication and thus shorten recovery. Outcome-based evidence for this procedure is still being assembled. Methods: Single-port cholecystectomy patients were matched based on age and gender with control patients undergoing four-port cholecystectomy during the same time. The primary endpoint was in hospital use of narcotic pain medication, measured by morphine equivalents. Secondary endpoints were operative time and length of stay. Statistical analysis was done by Student's t-test. Results: Fifty patients (36 women, 14 men) underwent single port cholecystectomy between 11/2009-7/2012 and 50 patients underwent traditional cholecystectomy during the same time period. All patients were matched within 10 years of age. Morbidity was 4% for the single port group, 0% for the traditional cholecystectomy. There were no conversions to open cholecystectomy. The single-port group required a median of 29.0 mg (range, 8.7-180 mg) morphine equivalents of pain medication and the control group required a median of 33.2 mg (range, 0-185.7 mg) morphine equivalents (P=0.04). Single port cholecystectomy operative times were longer (median, 85 vs. 77 minutes, P=0.03). Conclusion: In this small study, there is a statistically significant difference in narcotic use during the initial hospital stay was measured between the two groups. After the initial ten cases, the operative time for single-port cholecystectomy approximated the standard four-port cholecystectomy. Prospective randomized controlled trials are necessary to investigate differences in outcomes between the two approaches.

    ABSTRACT: BACKGROUND: Traditional metrics of postoperative outcomes (morbidity and mortality) are not useful to compare minimally invasive procedures with each other. Patient reported outcomes, such as quality of life (QOL) scores, offer an alternative approach. Compared with a large body of data in cancer treatment, the responsiveness of these instruments for minimally invasive surgery is not well described. To better define expected differences, we analyzed the reported QOL outcomes in randomized, controlled trials (RCTs) comparing single and four-port laparoscopic cholecystectomy. METHODS: Searching Medline, Embase, Psychinfo, Scopus, and the Cochrane Library (1946 to Jan 2012), two independent reviewers identified RCTs comparing single with four-port cholecystectomy in adult patients using perioperative QOL assessments. The quality of the studies was assessed regarding trial design and QOL reporting. RevMan was used for mathematical analysis of the pooled outcome data using a random-effects model. Standardized mean difference estimation was utilized when pooling studies reporting different QOL tools. Statistical heterogeneity was assessed using χ(2) and I(2). RESULTS: Of 743 citations, 37 RCTs were identified. Five studies with a total of 502 patients compared single with four-port cholecystectomy on QOL and were included. Pooled analysis was performed using preoperative and 1-month postoperative outcomes. At 1 month postoperatively, the reported effect size of perioperative QOL changes was up to 5 points (~1/2 SD) on the global SF 12 score. The largest difference in change of perioperative physical functioning was 9.9 points (~1 SD). No difference between the treatments was demonstrated. CONCLUSIONS: Reporting of QOL may improve the comparison of minimally invasive surgical procedures. This systematic review reports clinically important changes and did not demonstrate a difference between treatments at 1 month postoperatively. The optimal timing and trial design for QOL tools in this setting needs to be defined further.

    ABSTRACT: BACKGROUND: Ulcer perforation carries up to a 30 % 1-year mortality rate. Intervention-related adverse events are among statistically significant predictors of 1-year mortality. A natural orifice transluminal endoscopic surgical (NOTES) approach may be less invasive and may decrease procedure-related adverse events by diminishing the so-called second hit, thus leading to decreased morbidity and mortality. We sought to assess the feasibility of an endoscopic transluminal omental plug technique in patients with perforated gastroduodenal ulcers under laparoscopic guidance. METHODS: Patients with suspected acute gastroduodenal ulcer perforations were offered participation in this prospective pilot study. Closure of the perforation was attempted using the NOTES omental plug technique. Demographic, clinical, endoscopic, and radiographic data were abstracted, as were data for morbidity, mortality, and pilot data regarding quality of life (QOL). RESULTS: From February 2010 through February 2012, a total of 17 patients presented to a tertiary care center with clinically suspected perforated ulcer. Of seven patients (mean age 79 years, range 64-89 years) who consented to the study, three underwent the study procedure. All patients had multiple comorbidities. Two patients presented with 4-6 mm perforated peptic ulcers and underwent successful laparoscopic-assisted NOTES omental and falciform ligament patch closure, respectively. Postoperative radiographic contrast studies showed no leak, and patients were discharged home on postoperative days 3 and 4. The third patient had undergone enterocutaneous fistula repair with herniorrhaphy 6 weeks before. Although a transluminal endoscopic approach was feasible, the omentum was under too much tension to be secured. This procedure was converted to an open omental patch repair. For all but one patient who provided consent, obtaining QOL data was feasible. CONCLUSIONS: Initial results from a laparoscopic-assisted NOTES approach for closure of perforated peptic ulcers appear promising and enable swift recovery in selected patients. This is especially important in elderly and/or immunocompromised patients. Technical details and patient selection criteria continue to evolve.

    ABSTRACT: Endoscopic perforations are surgically repaired by using an omentum patch. Omentum substitutes may have broader applications particularly in certain sites (eg, esophagus). Evaluate a self-expandable foam matrix plug as a synthetic omentum substitute for repairing iatrogenic gastric perforations in a 4-week survival pig model. Experimental pilot study. Laboratory. A laparoscopic plug repair of a 1-cm, full-thickness, gastric perforation was carried out by using either a polyurethane foam matrix plug (FMP, 8 animals) or an omentum plug (OP, 6 animals, control group). Follow-up endoscopy was carried out at 1 and 4 weeks. At necropsy, the perforation site was evaluated for adhesions and histology by using hematoxylin and eosin analysis. A portion of the implant was sent for bacterial and fungal culture. All procedures were technically simple and successful. Thirteen animals thrived well for 4 weeks. One animal from the FMP group died 3 days postoperatively from diffuse peritonitis because of a misplaced plug. All remaining FMPs were intact at 4 weeks and colonized with mixed bacteria, except one animal presenting with FMP migration after 1 week. Histologically, the FMP group had more prominent inflammation and suppuration as compared with the OP group, all limited to its adjacent tissue. Animal study. The FMP offered a technically simple and feasible option for repairing iatrogenic gastric perforations. With effective sealing, the clinical outcome is similar to that of an omentum patch repair. Migration and inadequate sealing is a concern, which can lead to peritonitis and sepsis. Further development is needed to improve FMP performance.

    ABSTRACT: Pancreatic and esophageal cancers are both gastrointestinal malignancies with relatively low long term survival. In part, the aggressiveness of these tumors is related to local and distant metastatic potential, subsequently affecting prognosis and treatment modalities. Currently, the mainstay of staging involves in-depth radiographic imaging with surgery offered for potentially curative tumors. As a result, staging becomes a key determinant in the role of surgical resection. As minimally invasive approaches continue to gain popularity, the idea of natural orifice surgery has been raised as a possible adjunct to staging neoplasias. Currently, the insertion of a perioral endoscope to gain access to the peritoneal cavity via a transgastric incision has been investigated, with demonstration of feasibility and efficacy in several animal studies and limited clinical studies. Similar techniques have been employed to gain access to the thoracic cavity via a transesophageal incision in early animal studies. This article aims to outline the advantages and limitations of natural orifice endoscopic surgery, and review the use of endoscopic techniques to assess the intraperitoneal cavity via a transgastric incision for determining local and widespread metastases with reference to pancreatic carcinoma. The method of transesophageal staging for esophageal carcinoma will also be discussed.

    ABSTRACT: Lymphadenectomy is a surgical technique for staging and treating cancer. Laparoscopic lymphadenectomy for obese patients is challenging. Laparoscopic ultrasound-assisted liposuction (UAL) has been successful in porcine models. The current study aimed to evaluate whether UAL facilitates pelvic laparoscopic lymphadenectomy in obese subjects. The UAL technique was evaluated in two human cadavers and in six obese Ossabaw pigs. Both a standard and a prototype ultrasonic probe with a wider contact surface were tested. Pelvic lymphadenectomy comparing UAL with standard monopolar cautery was performed using obese Ossabaw pigs. The animals were survived for 2 weeks. Descriptive data regarding intra- and postoperative outcomes were recorded, including histologic analysis of dissected tissue after 2 weeks. Cytologic analysis of aspirated fluid coming from UAL also was recorded. The UAL procedure was safely performed for all the cadavers and animals. Lymph node exposure and clean exposure of surrounding structures were dramatic compared with monopolar assisted dissection. One animal was excluded from further analysis due to ultrasonic device malfunction (a broken footswitch cord). In general, UAL notably debulks adipose tissue with dramatic field exposure. Postoperative adhesions were present in all animals undergoing either monopolar or UAL dissection. Histology showed areas of foreign body reaction from mild to severe, with no predominance of either extreme seen with monopolar or UAL dissection. Cytologic analysis of collected pooled oil emulsion did not contain lymph node tissue. The UAL approach permits pelvic lymphadenectomy in the obese animal and cadaver model, with excellent exposure of lymph nodes and surrounding pelvic anatomy. The use of a new ultrasonic prototype probe with a wider contact surface allowed dissection with less mechanical and thermal penetration of tissue. Further studies are needed to assess oncologic safety (cancer cell dissemination), postoperative healing, and adhesion formation.

    ABSTRACT: Esophageal myotomy using submucosal endoscopy with mucosal safety flap (SEMF) has been proposed as a new treatment of achalasia. In this technique, a partial-thickness myotomy (PTM) preserving the longitudinal outer esophageal muscular layer is advocated, which is different from the usual full-thickness myotomy (FTM) performed surgically. The aim of this study was to compare endoscopic FTM and PTM and analyze the outcomes of each method after a 4 week survival period. Twenty-four pigs were randomly assigned into group A (FTM, 12 animals) and group B (PTM) to undergo endoscopic myotomy. Lower esophageal sphincter (LES) pressure was assessed using pull-through manometry. For statistical analysis we compared the average esophageal sphincter pressure values at baseline, after 2 weeks, and after 4 weeks between groups A and B. The P value was set as <0.05 for significance. Eighteen animals were included for statistical analysis. Mean (SD) LES pressures were similar between groups A and B (nine animals each) at baseline [group A = 23 (10.4) mmHg; group B = 20.7 (8.7) mmHg; P = 0.79], after 2 weeks [group A = 19 (7.7) mmHg; group B = 21.8 (8.4) mmHg; P = 0.79], and after 4 weeks [group A = 22.6 (10.2) mmHg; group B = 20.7 (9) mmHg; P = 0.82]. LES pressures were significantly reduced in three animals after 4 weeks: one animal (1%) in group A and two animals (2.5%) in group B. An extended myotomy (3 cm below the cardia) was achieved in three animals and was responsible for the significant drop in LES pressure seen in the two animals from group B. Esophageal myotomy using SEMF is a feasible yet challenging procedure in pigs. Full-thickness myotomy does not seem to be superior to partial-thickness myotomy as demonstrated by pull-through manometry. Endoscopic esophageal myotomy results are greatly influenced by obtaining adequate myotomy extension into the gastric cardia.

    ABSTRACT: Perforation accounts for 70% of deaths attributed to peptic ulcers. Laparoscopic repair is effective but infrequently used. Our aim was to assess how many patients with perforated peptic ulcer could be candidates for a transluminal endoscopic omental patch closure. This retrospective study reviewed patients with perforated peptic ulcer from 2005 to 2010. Demographics, ulcer characteristics, operative procedure, and outcomes were recorded. Candidates for endoscopic transluminal repair were defined as those having undergone omental patch closure of an ulcer of appropriate size and no contraindications to laparoscopy or endoscopy. In the retrospective review, a total of 104 patients were identified; 62% female, mean age = 68 years, mean ASA of 3, and 63% medication-related ulcers. Fifty-nine (63%) had an omental patch (80% open), and 35 (37%) had other procedures. Ten patients had nonoperative management. Thirty-day mortality was 14% and 1 year mortality was 35%. Forty-nine patients (52%) were considered potential candidates for transluminal repair. Sixty-three percent of our patients sustained a medication-related perforation with 1 year mortality of 35%. The majority of patients were treated using open omental patch repair. Transluminal endoscopic repair may provide an additional situation for a minimally invasive approach for a number of these patients.

    ABSTRACT: Prior surveys evaluating women's perceptions of transvaginal surgery both support and refute the acceptability of transvaginal access. Most surveys employed mainly quantitative analysis, limiting the insight into the women's perspective. In this mixed-methods study, we include qualitative and quantitative methodology to assess women's perceptions of transvaginal procedures. Women seen at the outpatient clinics of a tertiary-care center were asked to complete a survey. Demographics and preferences for appendectomy, cholecystectomy, and tubal ligation were elicited, along with open-ended questions about concerns or benefits of transvaginal access. Multivariate logistic regression models were constructed to examine the impact of age, education, parity, and prior transvaginal procedures on preferences. For the qualitative evaluation, content analysis by independent investigators identified themes, issues, and concerns raised in the comments. The completed survey tool was returned by 409 women (grouped mean age 53 years, mean number of 2 children, 82% ≥ some college education, and 56% with previous transvaginal procedure). The transvaginal approach was acceptable for tubal ligation to 59%, for appendectomy to 43%, and for cholecystectomy to 41% of the women. The most frequently mentioned factors that would make women prefer a vaginal approach were decreased invasiveness (14.4%), recovery time (13.9%), scarring (13.7%), pain (6%), and surgical entry location relative to organ removed (4.4%). The most frequently mentioned concerns about the vaginal approach were the possibility of complications/safety (14.7%), pain (9%), infection (5.6%), and recovery time (4.9%). A number of women voiced technical concerns about the vaginal approach. As in prior studies, scarring and pain were important issues to be considered, but recovery time and increased invasiveness were also in the "top five" list. The surveyed women appeared to actively participate in evaluating the technical components of the procedures.

    ABSTRACT: Early surgical involvement in the management of a patient at high risk for recurrent bleeding, despite endoscopic intervention, is often optimal to assure continuity of care. Close collaboration of the surgical team with gastroenterologic endoscopy teams greatly benefits the patient. A detailed description of the location of the bleeding process is of great help for the surgeon as surgical decision making will be influenced by the distance from the gastroesophageal junction or pylorus, location on the anterior or posterior wall, greater or lesser curvature or incisura, and the size of the process.

    ABSTRACT: Laparoscopy, which is a minimally invasive surgery, is associated with decreased peritoneal adhesions and inflammatory response compared with laparotomy. To evaluate whether natural orifice transluminal endoscopic surgery (NOTES) leads to an attenuated peritoneal response compared with laparoscopy. Pooled histologic analysis from 2 randomized porcine trials. Laboratory. Histologic analysis of swine undergoing diagnostic laparoscopy, diagnostic NOTES peritoneoscopy, NOTES with transgastric mesh placement, or diagnostic endoscopy (no gastrotomy) followed by laparoscopic mesh placement. The presence and grade of inflammation in necropsy specimens of lung, liver, and spleen as reviewed by a blinded veterinary pathologist. Four NOTES mesh animals exhibited mesh infections at necropsy. Tissue from 48 swine were available for analysis. Pulmonary inflammation, liver fibrosis, and spleen capsulitis were the primary findings. No difference was seen in the incidence of each finding among groups. The severity of the pulmonary inflammation in the laparoscopy group was significantly higher than in the NOTES groups. The NOTES mesh group exhibited significantly more severe liver fibrosis and spleen capsulitis. There was no difference between clinical behavior, serum white blood cell count, or peritoneal white blood cell count among groups in either study. Intra-abdominal pressures during NOTES were lower than during laparoscopy. Pooled analysis of 2 separate studies. More severe pulmonary inflammation was found in animals undergoing longer laparoscopic procedures with higher intra-abdominal pressures. Intraperitoneal inflammation was most significant with transgastric mesh placement, likely caused by infections.
