Studies to date show contrasting conclusions when comparing intracorporeal and extracorporeal anastomoses for minimally invasive right colectomy. Large multi-center prospective studies comparing perioperative outcomes between these two techniques are needed. The purpose of this study was to compare intracorporeal and extracorporeal anastomoses outcomes for robotic assisted and laparoscopic right colectomy. Multi-center, prospective, observational study of patients with malignant or benign disease scheduled for laparoscopic or robotic-assisted right colectomy. Outcomes included conversion rate, gastrointestinal recovery, and complication rates. There were 280 patients: 156 in the robotic assisted and laparoscopic intracorporeal anastomosis (IA) group and 124 in the robotic assisted and laparoscopic extracorporeal anastomosis (EA) group. The EA group was older (mean age 67 vs. 65 years, p = 0.05) and had fewer white (81% vs. 90%, p = 0.05) and Hispanic (2% vs. 12%, p = 0.003) patients. The EA group had more patients with comorbidities (82% vs. 72%, p = 0.04) while there was no significant difference in individual comorbidities between groups. IA was associated with fewer conversions to open and hand-assisted laparoscopic approaches (p = 0.007), shorter extraction site incision length (4.9 vs. 6.2 cm; p ≤ 0.0001), and longer operative time (156.9 vs. 118.2 min). Postoperatively, patients with IA had shorter time to first flatus, (1.5 vs. 1.8 days; p ≤ 0.0001), time to first bowel movement (1.6 vs. 2.0 days; p = 0.0005), time to resume soft/regular diet (29.0 vs. 37.5 h; p = 0.0014), and shorter length of hospital stay (median, 3 vs. 4 days; p ≤ 0.0001). Postoperative complication rates were comparable between groups. In this prospective, multi-center study of minimally invasive right colectomy across 20 institutions, IA was associated with significant improvements in conversion rates, return of bowel function, and shorter hospital stay, as well as significantly longer operative times compared to EA. These data validate current efforts to increase training and adoption of the IA technique for minimally invasive right colectomy.

For years, the conventional laparoscopically assisted colon resection has been the most accepted approach worldwide for all pathologies in the right colon, left colon, and rectum. The necessity of an abdominal incision to retrieve the specimen is accompanied by a significant number of complications, such as infection, incisional hernia, pain, longer hospital stay, and more discomfort for the patient.

Objective:To assess readiness of general surgery graduate trainees entering accredited surgical subspecialty fellowships in North America. Methods:A multidomain, global assessment survey designed by the Fellowship Council research committee was electronically sent to all subspecialty program directors. Respondents spanned minimally invasive surgery, bariatric, colorectal, hepatobiliary, and thoracic specialties. There were 46 quantitative questions distributed across 5 domains and 1 or more reflective qualitative questions/domains. Results:There was a 63% response rate (n = 91/145). Of respondent program directors, 21% felt that new fellows arrived unprepared for the operating room, 38% demonstrated lack of patient ownership, 30% could not independently perform a laparoscopic cholecystectomy, and 66% were deemed unable to operate for 30 unsupervised minutes of a major procedure. With regard to laparoscopic skills, 30% could not atraumatically manipulate tissue, 26% could not recognize anatomical planes, and 56% could not suture. Furthermore, 28% of fellows were not familiar with therapeutic options and 24% were unable to recognize early signs of complications. Finally, it was felt that the majority of new fellows were unable to conceive, design, and conduct research/academic projects. Thematic clustering of qualitative data revealed deficits in domains of operative autonomy, progressive responsibility, longitudinal follow-up, and scholarly focus after general surgery education.

This prospective study focused on patients with rectal cancer who underwent transanal specimen extraction after laparoscopic anterior resection with total mesorectal excision and specifically aims to investigate whether the transanal approach can be accepted as a safe and effective method for extracting the malignant specimen from the peritoneal cavity.

BACKGROUND:This study was designed to compare laparoscopic peritoneal lavage and drainage (LLD) with laparoscopic Hartmann's procedure (LHP) in the management of perforated diverticulitis and to investigate a safer and more effective laparoscopic method for managing acute perforated diverticulitis with generalized peritonitis.METHODS:A consecutive series of patients who underwent emergent LHP or LLD for perforated diverticulitis were identified from a prospectively designed database. All procedure-related information was collected and analyzed. P < 5 % was considered statistically significant in this study.RESULTS:A total of 88 patients underwent emergent laparoscopic procedures (47 LLD and 41 LHP) between 1995 and 2010 for acute perforated diverticulitis. Diagnostic laparoscopy classified 74 (84.1 %) patients as Hinchey III or IV perforated diverticulitis. OT for LHP was 182 ± 54.7 min, and EBL was 210 ± 170.5 ml. Six LHP (14.6 %) were converted to open Hartmann's for various reasons. Moreover the rates of LHP-associated postoperative mortality and morbidity were 2.4 and 17.1 %, respectively. For LLD, the operating time was 99.7 ± 39.8 min, and blood loss was 34.4 ± 21.2 ml. Three patients (6.4 %) were reoperated for the worsening of septic symptoms during post-LLD course. Moreover, the patients with LHP had significantly longer hospital stay than the ones with LLD did (16.3 ± 10.1 vs. 6.7 ± 2.2 days, P < 0.01). In the long-term follow-up, the rate of colostomy closure for LHP is 72.2 %, and 21 of 47 patients who underwent LLD had elective sigmoidectomy for the source control with the rate of 44.7 %.CONCLUSIONS:Both LHP and LLD can be performed safely and effectively for managing severe diverticulitis with generalized peritonitis. Compared with LHP, LLD does not remove the pathogenic source; however, the clinical application of this damage control operation to our patients showed significantly better short- and long-term clinical outcomes for managing perforated diverticulitis with various Hinchey classifications.

Background. Management of the open abdomen (OA) is challenging for surgeons and requires experienced medical teamwork. The need for improvements in temporary abdominal closure methods has led to the development of a negative-pressure therapy (NPT; ABThera OA NPT, KCI USA, Inc, San Antonio, TX). Method. The authors present a 19-patient case series documenting their use of NPT for OA management in nontraumatic surgery. All received NPT until the fascia was considered ready for closure. Results. Of 19 patients, 17 (89.5%) achieved fascial closure with a Kaplan-Meier (KM) median time to closure of 6 days. Mean hospital and intensive care unit stays were 32.1 and 26.6 days, respectively. During their hospitalization, 5 patients (26.3%) died, with a KM median time to mortality of 53 days. Conclusion. These findings demonstrate effective use of NPT for managing the OA in critically ill patients, and this has led the authors to use it in their general surgery practice.

Minimally invasive techniques have revolutionized the art of surgical practice. The laparoscopic approach to cholecystectomy has become the gold standard and is the most common laparoscopic general surgery procedure worldwide. In an effort to further enhance the advantages of laparoscopic surgery even less-invasive methods have been attempted, including smaller and fewer incisions. The objective of this study was to describe our results with over 15 years of needlescopic cholecystectomies. At the Texas Endosurgery Institute, 434 operations were done by a single surgeon from 1995 to 2010. Eighty-six percent of subjects were female, and the average age of all subjects was 41.9 years (range 14-82). The average operating time was 59.3 minutes (range 30-200). The 200-minute operation required laparoscopic CBD exploration, accounting for the extended time. Average estimated intraoperative blood loss (EBL) was <15 cc (range 0-50 cc). Two percent of cases required conversion to standard 5-mm cholecystectomy and were completed without incident. All patients are followed up at two weeks and then at six months. Since 1995, only one patient presented with a hernia at the umbilical site. Otherwise, no wound, bile duct, bile leak, bleeding, or thermal injury complications have been identified.

Background Natural orifice transluminal endoscopic surgery (NOTES) is the anticipated progression of minimally invasive surgery. As it approaches, surgeons will need to develop the fundamental skills and spatial orientation needed to perform safely in this new field. The Natural Orifice Surgery Consortium for Assessment and Research has established several fundamental challenges to the safe introduction of NOTES. Our institutional experience with laparoscopic-assisted endoluminal surgery is reviewed to display the techniques and efficacy of procedures that address many of these challenges and may provide a safe transition for the general surgeon to NOTES or as an alternative to pure NOTES. Methods A retrospective review of all laparoscopic-assisted endoluminal surgeries from 1991 to 2007 was performed. Patients had been referred to the institution and selected after either unsuccessful attempts from traditional endoscopic resection of pathology by a gastroenterologist or being deemed an unfavorable candidate for traditional endoscopic resection. All procedures involved establishment of pneumoperitoneum, placement of trochar ports under laparoscopic visualization, balloon ports in gastric cases combined with endoscopy, intraluminal insufflation, coordinated resection of intraluminal pathology using both the endoscopic and laparoscopic instruments, and closure of the intraluminal port sites with intracorporeal suturing. Results A total of 175 procedures were performed from 1991 to 2007 using these techniques. These procedures varied and included laparoscopic monitored colonoscopic polypectomy, resection of gastric polyps, intraluminal cystgastrostomy, gastric ulcer resection, and foreign body removal. The average age was 55 years (range 38 to 75 y), length of operation 95 minutes (range 60 to 137 min), hospital stay 3.5 days, and 5 complications (2.8%). Of the total procedures, 18 (10.2%) patients were found to have malignancy on frozen section and preceded with a formal resection. There are no cancer recurrences to date with a mean follow up of 74 months (6 to 196 mo). Conclusions Our institutional experience with these procedures seems to be a natural transition to developing skills for NOTES procedures and displays a safe and effective approach to a wide range of intraluminal pathology. The general surgeon in practice can use this union of laparoscopy and endoscopy using current instruments and technology for safe transition into the emerging field of NOTES, or even as an alternative to pure NOTES. Mastery of intraoperative endoscopy and intraluminal surgery will be essential to this transition.

Introduction Intraluminal surgery began with the advent of endoscopy. Endoscopic endoluminal surgery has limitations; and its failure results in conventional open or laparoscopic interventions with increased morbidity. Laparoscopy-assisted intraluminal surgery is a novel alternative to open or laparoscopic surgery for a failed endoscopic endoluminal technique, minimizing the associated complications. Endoscopic resection of early gastric and duodenal cancers is restricted by the limited view of the endoscope, insufficient number of instrument channels, and inability to have adequate margins of resection without risking perforation. These cancers potentially can be treated by laparoscopy-assisted intraluminal surgery without resorting to major gastric or duodenal resection. This procedure is relatively easy to perform and oncologically effective. We present the experience of the Texas Endosurgery Institute (TEI) in treating early gastric and duodenal cancers, including large malignant polyps and carcinoid tumors, with laparoscopy-assisted endoluminal surgery. Materials and methods The data for all patients with early gastric and duodenal cancers who underwent laparoscopy-assisted endoluminal surgery at TEI between 1996 and 2007 were prospectively recorded. All of the patients had been referred by the endoscopist as noncandidates for endoscopic resection. We prospectively collected data on preoperative diagnosis, operating time, estimated blood loss, postoperative complications, histopathology, and recurrence rate. All patients underwent endoluminal port placement under direct visualization after a pneumoperitoneum was established. Operations were performed in conjunction with upper endoscopy for assistance with port placement under endoluminal visualization, insufflation, and specimen retrieval. After the intraluminal portion of the operation was completed, the endoluminal port sites were closed with laparoscopic intracorporeal suturing. Results From 1996 to 2007, a total of 12 patients underwent laparoscopic endoluminal surgery. All cases were completed successfully, including 5 resections of early gastric cancer (stage I), 3 wedge resections of carcinoid tumor, 2 resections of duodenal adenocarcinoma, and 2 resections of a malignant polyp at the gastroesophagic junction; all the cases were completed with disease-free margins. No recurrence of the original pathology have been reported, and the complications were minimal. Conclusion Laparoscopic intraluminal surgery for early gastric and duodenal cancer is a feasible alternative to open conventional therapies; and it is associated with a lower incidence of incisional hernia formation and a lower infection rate.

BACKGROUND:The treatment of perforated diverticulitis is changing form the current standard of laparotomy with resection, Hartmann procedure, and colostomy to a minimally invasive technique. In patients with complicated acute diverticulitis and peritonitis without gross fecal contamination, laparoscopic peritoneal lavage, inspection of the colon, and intraoperative drain placement of the peritoneal cavity appears to alleviate morbidity and improve the outcome. In this article, we report our experience of a laparoscopic peritoneal lavage technique with delayed definitive resection when necessary.METHOD AND MATERIALS:Records of patients who underwent intraoperative peritoneal lavage for purulent diverticulitis at the Texas Endosurgery Institute from April 1991 to September 2006 were retrospectively reviewed.RESULTS:Forty patients were included in the study, with a male/female ratio of 26:14. The average age was 60 years. Many had associated co-morbidities. The average operating time was 62 minutes. There were no conversions to an open procedure. Apart from mild postoperative paralytic ileus in six patients and chest infections in two, there were no significant peroperative or postoperative complications. Just over 50% underwent elective interval laparoscopic sigmoid colectomy. During the mean follow-up of 96 months, none of the other patients required further surgical intervention.CONCLUSION:Laparoscopic lavage of the peritoneal cavity and drainage is a safe alternative to the current standard of treatment for the management of perforated diverticulitis with or without gross fecal contamination. It is associated with a decrease in the overall cost of treatment; the use of a colostomy is avoided; patient improvement is immediate; and there is a reduction in mortality and morbidity as definitive laparoscopic resection can be performed in a nonemergent fashion. Perhaps the most important benefit, other than avoiding a colostomy, is the association of fewer wound complications such as dehiscence, wound infection, and the high risk of hernia formation. Laparoscopic lavage and drainage should be considered in all patients in whom medical and/or percutaneous treatment is not feasible. It carries minimal morbidity and should be considered the standard of care.

BACKGROUND:Frequently, critically ill patients suffer from intraabdominal pathology, such as sepsis or ischemia, either as a cause of a critical illness or as a complication from another illness requiring an intensive care unit (ICU) admission. These complications are associated with high rates of morbidity and mortality (between 50% to 100%). The diagnosis of these problems can be difficult in these very ill patients because it may require transport of unstable patients to additional departments outside the ICU setting. One option in the diagnosis of these difficult patients is bedside laparoscopy, as it avoids patient transport, is very accurate, and maintains ICU monitoring.METHODS:From 1991 to 2003, 13 patients underwent bedside diagnostic laparoscopy in the ICU to diagnose intraabdominal pathology in critically ill patients. All the procedures were done at the bedside in the ICU with the patient under local anesthesia and intravenous sedation.RESULTS:Mean procedure time was 36 minutes (range, 17 to 55). Mean patient age was 75.5 years (range, 56 to 86). There were 8 males and 5 females. Forty-six percent of the patients were diagnosed with mesenteric necrosis and died within 48 hours with no further testing or procedures. One patient with massive fecal contamination died the same day. Thirty percent of patients had a normal intraabdominal examination; of these, 2 died of unrelated illnesses and 2 survived their nonabdominal illness. Fifteen percent were diagnosed with acute acalculous cholecystitis as a complication of their ICU illness, which resolved satisfactorily. No intraoperative complications occurred with the ICU procedure.CONCLUSION:Bedside diagnostic laparoscopy in the ICU is feasible, safe, and accurate in the assessment of possible intraabdominal problems in properly selected, critically ill patients.

OBJECTIVES:Needlescopic cholecystectomy (NC) is a refinement of laparoscopic cholecystectomy (LC) using 2-mm instruments compared with the standard 5-mm and 10-mm ports. We review our experience with needlescopic cholecystectomy.METHODS:From 1994 to 2004, 303 patients underwent NC. All patients were operated on using 2-mm instruments and one 10-mm trocar for the laparoscope. The characteristics of patients, total operation time, complications, postoperative pain, and hospital course were documented.RESULTS:Patients' average age was 41.86 years; 262 were female and 41 were male. Mean BMI was 25.7. Mean length of surgery was 59.33 minutes. Intraoperative cholangiography was performed in all cases. Mean blood loss was 14.88 mL. One intraoperative complication occurred. Mean hospital stay was 22.68 hours. Postoperative pain was measured on a 0-10 pain scale; on day 0 it was 4.4 and on the first day it was 1.7. Analgesic doses required were 0 doses in 6.89%, 1 in 20.68%, 2 in 24.13%, 3 in 34.48%, 4 in 13.79%, and > 4 doses was not required. No postoperative complications occurred. At 3-month follow-up, patient satisfaction was 100%, and in 99% of patients scars were imperceptible.CONCLUSIONS:NC is safe and feasible without increased operative risk, with better cosmetic results, less pain, and good acceptance among patients.
