Abstract
OBJECTIVE To determine the diagnostic accuracy of tissue impedance measurement interpretation (TIMI) for determining correct versus incorrect Veress needle placement in feline cadavers. STUDY DESIGN Prospective, randomized, blinded trial. STUDY POPULATION Cat cadavers (n = 24). METHODS Two laparoscopists (1 experienced, 1 novice), blinded to TIMI, placed reusable Veress needles in study subjects in a randomized order. A third individual interpreted impedance measurements as consistent with correct versus incorrect placement. Veress needle tip locations were marked by injecting contrasting colors of India ink. Tissue dissection was performed to localize ink. Sensitivity, specificity, accuracy, precision, and kappa statistics for TIMI for placements by the experienced and novice laparoscopist were determined. P < .05 was considered significant. RESULTS TIMI identified 36/38 correct and 2/10 incorrect placements. TIMI identified 2/2 bowel perforations but was unable to identify 8 inappropriate placements in the retroperitoneal fat pad. Impedance measurement interpretation had 94.7% sensitivity, 20% specificity, 79.2% accuracy, and 81% precision overall. Agreement between TIMI and Veress needle location was absent (kappa = -0.15, P = .01) for placements by the experienced laparoscopist and substantial (kappa = 0.78, P < .01) for the novice laparoscopist. CONCLUSIONS Failure of TIMI to identify placement in the retroperitoneal fat pad resulted in poor accuracy. Small cat size limited the number of appropriate placement sites, perhaps resulting in excessively dorsal placements. Use of TIMI may increase detection of clinically significant inappropriate Veress needle placements, like bowel perforations, and decrease installment phase complications. Further evaluation of Veress needle placement with and without TIMI is warranted.

Abstract
Laparoscopy has become a valuable tool for the gynaecologist in the diagnosis and treatment of a variety of gynecological disorders. Its quicker recovery time and other advantages has benefitted countless women. Laparoscopic procedures, however, have their own associated risks and complications, and the surgeon must become thoroughly familiar with these. This awareness will help reduce patient morbidity and mortality, and potentially avoid the stress and burden of litigation, which has been increasing in recent years. Complications of gynaecologic laparoscopy include entry-related problems, and injuries to bowel, urinary tract, blood vessels, and nerves. Although some of these complications have been well described, some have emerged recently in relation to new technology and techniques. In this chapter, we discuss some of the complications of endoscopic surgery, including their incidence, prevention, and medico-legal implications, and provide a brief overview of their management.

Abstract
BACKGROUND Body piercing has become increasingly popular throughout the world and may cause unanticipated complications during surgery. METHODS We describe the case of a 35-y-old woman with hepatocellular carcinoma who underwent a diagnostic laparoscopy for metastatic disease evaluation. RESULTS An early intestinal injury occurred upon abdominal entry and introduction of pneumoperitoneum. The injury was secondary to a single adhesion between the abdominal wall and small bowel caused by a previous umbilical piercing. CONCLUSIONS Umbilical piercing can lead to unanticipated intraoperative complications even if it is removed prior to surgery. Surgeons performing laparoscopy should be aware of potential pitfalls associated with these art forms.

Abstract
This report emphasizes the importance of performing meticulous closure on all trocar sites 10-mm and greater. Background: Nonbladed trocars are considered less traumatic to the abdominal wall due to the lack of fascial incision. It has been suggested that closure of the abdominal fascia may be unnecessary when such nonbladed trocars are used. Case Report: We report on 2 patients who were diagnosed with trocar-site hernias 2 days after laparoscopic appendectomy performed using 11-mm nonbladed trocars. Conclusion: Although rare, trocar-site hernias after laparoscopic surgery with nonbladed trocars remain a cause of postoperative morbidity and require prompt intervention. Therefore, this report underscores the significance of performing meticulous closure of all trocar sites that are ≥10mm.

Abstract
The Dutch Society for Endoscopic Surgery together with the Dutch Society of Obstetrics and Gynecology initiated a multidisciplinary working group to develop a guideline on minimally invasive surgery to formulate multidisciplinary agreements for minimally invasive surgery aiming towards better patient care and safety. The guideline development group consisted of general surgeons, gynecologists, an anesthesiologist, and urologist authorized by their scientific professional association. Two advisors in evidence-based guideline development supported the group. The guideline was developed using the "Appraisal of Guidelines for Research and Evaluation" instrument. Clinically important aspects were identified and discussed. The best available evidence on these aspects was gathered by systematic review. Recommendations for clinical practice were formulated based on the evidence and a consensus of expert opinion. The guideline was externally reviewed by members of the participating scientific associations and their feedback was integrated. Identified important topics were: laparoscopic entry techniques, intra-abdominal pressure, trocar use, electrosurgical techniques, prevention of trocar site herniation, patient positioning, anesthesiology, perioperative care, patient information, multidisciplinary user consultation, and complication registration. The text of each topic contains an introduction with an explanation of the problem and a summary of the current literature. Each topic was discussed, considerations were evaluated and recommendations were formulated. The development of a guideline on a multidisciplinary level facilitated a broad and rich discussion, which resulted in a very complete and implementable guideline.

Abstract
CONTEXT: Veress needle insertion (VNI) at sub-umbilical fold (SUF) midline is associated with serious intra-abdominal injuries. AIM: The aim of this study has been to evaluate the safety and efficacy of lower left intercostal space (LICS) for VNI. SETTINGS AND DESIGN: This prospective observational study was conducted in three parts in Surgery-II, Department of Surgery, GTBH-UCMS, Delhi. MATERIALS AND METHODS: In part one, skin fold thickness (SFT) was measured in 32 patients at SUF, LICS, right iliac fossa (RIF) and Palmer's point. As part two, in these patients, VNI was carried out from LICS under laparoscopic guidance. As part three, same technique of VNI was employed in 43 patients with suspected intra-abdominal adhesions undergoing laparoscopy for various reasons. Observations were made regarding ease of insertion, attempts needed for successful entry, loudness or clarity of give-way feeling of Veress needle, intra-abdominal bleeding at point of emergence of Veress needle, hemopneumothorax, bowel or vascular injury. STATISTICAL ANALYSIS USED: SFT was expressed as mean (SD), and one-way ANOVA followed by Tukey's test were employed to find the statistical significance. RESULTS: SFT at LICS was significantly less as compared to SUF and Palmer's point. VNI at LICS was easy to carry out; it could be successfully done in first attempt in all patients, and was associated with very clear and loud give-way feeling. There were no instances of intra-abdominal bleeding at point of emergence of Veress needle, hemopneumothorax, bowel or vascular injury. CONCLUSIONS: VNI at LICS as described here is safe and effective.

Abstract
Endometriosis is a highly enigmatic disease with multiple presentations ranging from infertility to severe pain, often causing significant morbidity. Video-assisted laparoscopy (VALS) has now replaced laparotomy as the gold standard for the diagnosis and management of endometriosis. While imaging has a role in the evaluation of some patients, histologic examination is needed for a definitive diagnosis. Laboratory evaluation currently has a minor role in the diagnosis of endometriosis, although studies are underway investigating serum markers, genetic studies, and endometrial sampling. A high index of suspicion is essential to accurately diagnose this complex condition, and a multidisciplinary approach is often indicated. The following review discusses laparoscopic diagnosis of endometriosis from the pre-operative evaluation of patients suspected of having endometriosis to surgical technique for safe and adequate laparoscopic diagnosis of the condition and postsurgical care.

Abstract
INTRODUCTION The use of laparoscopy as a diagnostic and therapeutic tool is being used increasingly in the emergency setting with many of these procedures being performed by trainees. While the incidence of iatrogenic injuries is reported to be low, we present six emergency or expedited cases in which the bladder was perforated by the suprapubic trocar. CASES Three cases were related to the management of appendicitis, two to negative diagnostic laparoscopies for lower abdominal pain and one to an ectopic pregnancy. Management of the bladder injuries varied from a urinary catheter alone to laparotomy with debridement of the abdominal wall due to sepsis and later reconstruction. Four of the six cases were performed by registrars. CONCLUSIONS Although the incidence of bladder injury is low, its importance is highlighted by the large number of laparoscopies being performed. In addition to catheterisation of the patient, care must be taken with the insertion of low suprapubic ports and consideration should be made regarding alternative sites. Adequate laparoscopic supervision and training in port site planning is required for surgical trainees.

Abstract
OBJECTIVE To determine patient preference for laparoscopic tubal occlusion or hysteroscopic tubal occlusion, two common sterilization interventions, and the acceptability of a postprocedure confirmation test for a hysteroscopic approach. PARTICIPANTS AND METHODS A total of 100 patients were offered two procedures. A description of each procedure was developed and read to each patient by a research nurse on site. Patients were then asked to respond to a questionnaire concerning options. Final informed consent, procedure review, and procedural date determination were provided by a physician upon completion of the questionnaire. Patients were not allowed to change their questionnaire responses after completion. No interviewer or physician input was allowed during the questionnaire. The study was completed in English or Spanish, as per patient request, by a bilingual/fluent speaker. Physicians completing informed consent were unaware of the questionnaire responses. Patients were not financially incentivized. RESULTS Of 100 participants, 93 (93%) preferred hysteroscopic sterilization to laparoscopy. The reasons were as follows: fear of general anesthesia (24/93 [26%]), fear of incision (25/93 [27%]), cost (32/93 [34%]), and time (12/93 [13%]) to return to routine activity. All 93 viewed "office-based location" as the main advantage over laparoscopy; 88/93 (94.6%) considered a confirmation test to be a benefit of the procedure. After informed consent was obtained, one additional patient switched from a laparoscopic decision to hysteroscopy (total = 94/100); 89/94 (95%) hysteroscopic decisions underwent hysteroscopic sterilization; 4/6 (67%) laparoscopic decisions proceeded to that surgery. The remainder (N = 7) cancelled due to lack of financial resources. CONCLUSION A nonincisional, office-based approach to sterilization has high patient acceptability. Patients viewed a confirmatory test for tubal occlusion as a benefit after sterilization.

Abstract
BACKGROUND The Veress needle (VN) technique for establishing pneumoperitoneum in laparoscopic surgery is widely used and yet is associated with slow insufflation rates and potentially life-threatening complications. Although these complications have been rarely reported, they represent a major source of morbidity and mortality from laparoscopic procedures and a major reason for conversion to open surgery. The open laparoscopy (OL) is an alternative to the VN technique, being relatively safer, even if considered cumbersome by many authors. Recently, the direct trocar insertion (DTI) technique of establishing pneumoperitoneum has been reported as an alternative to both techniques, but it is largely confined to gynecologic procedures. We report a case-series study where we evaluate the patients who underwent a DTI entry for laparoscopy during a recent 5-year period, focusing attention on feasibility, safety, and the benefits of DTI. METHODS This is a case series of 2175 different laparoscopic procedures (1456 [66.9%] scheduled cases and 719 [33%] emergencies). In 2091 (96.1%) of them (1425 [68.1%] scheduled cases and 666 [31.8%] emergencies), pneumoperitoneum was established with DTI, either in the umbilicus or in Palmer's point. RESULTS There were no injuries, either minor or major. Peritoneal access and the creation of a laparoscopic workplace were obtained quickly and efficiently by DTI. CONCLUSION Our results suggest that DTI is a fast, safe, and reliable alternative to traditional techniques for pneumoperitoneum establishment and should be regarded as a part of the surgical armamentarium of a trained laparoscopic surgeon.

Abstract
STUDY OBJECTIVE To establish whether time, pressure, or volume is the most reliable indicator of adequate pneumoperitoneum and, hence, the best parameter to use for safe trocar entry. DESIGN Prospective cohort study (Canadian Task Force classification II-2). SETTING Department of Endogynecology, Royal Hospital for Women, Sydney, Australia. PATIENTS One hundred thirty-three consecutive patients having gynecologic laparoscopy were recruited for the study. Of these, 100 patients were included in the analysis, and 33 were excluded. INTERVENTION Laparoscopic surgery. MEASUREMENTS AND MAIN RESULTS After umbilical Veress needle entry, pressure and volume were recorded every 20 seconds until insufflation pressure of 20 mm Hg was reached. Following trocar entry, the gas was then expelled with the patient lying flat. The depth of pneumoperitoneum was measured at intra-abdominal pressure of 5, 10, 15, and 20 mm Hg. Random effects models were used to predict the depth of pneumoperitoneum based on pressure, time, and volume. A comparison was made of the standard deviation of pneumoperitoneum distance produced at pressure of 20 mm Hg (8.56 ± 0.59) compared with that produced by a volume of 3 L (4.96 ± 1.13). Compared with volume, pressure was significantly more reliable in estimating depth of pneumoperitoneum (p < .001) because it exhibited the least variance. Further comparison was made of the standard deviation of pneumoperitoneum distance produced at pressure of 20 mm Hg (8.56 ± 0.59) compared with that produced at 3 minutes (7.82 ± 1.19). Compared with time, pressure was significantly more reliable in depth of pneumoperitoneum (p < .001) because it exhibited the least variance. These results demonstrate that, compared with volume and time, pressure is the most reliable predictor of pneumoperitoneum depth because it exhibits the least variance (p < .001). CONCLUSION Pressure is the most reliable predictor of pneumoperitoneum before trocar entry in laparoscopic surgery.

Abstract
BACKGROUND Laparoscopic surgery has gained popularity over open conventional surgery as it offers benefits to both patients and health care practitioners. Although the overall risk of complications during laparoscopic surgery is recognized to be lower than during laparotomy, inadvertent serious complications still occur. Creation of the pneumoperitoneum and placement of laparoscopic ports remain a critical first step during endoscopic surgery. It is estimated that up to 50% of laparoscopic complications are entry-related, and most injury-related litigations are trocar-related. We sought to evaluate the current practice of laparoscopic entry among Canadian general surgeons. METHODS We conducted a national survey to identify general surgeon preferences for laparoscopic entry. Specifically, we sought to survey surgeons using the membership database from the Canadian Association of General Surgeons (CAGS) with regards to entry methods, access instruments, port insertion sites and patient safety profiles. Laparoscopic cholecystectomy was used as a representative general surgical procedure. RESULTS The survey was completed by 248 of 1000 (24.8%) registered members of CAGS. Respondents included both community and academic surgeons, with and without formal laparoscopic fellowship training. The demographic profile of respondents was consistent nationally. A substantial proportion of general surgeons (> 80%) prefer the open primary entry technique, use the Hasson trocar and cannula and favour the periumbilical port site, irrespective of patient weight or history of peritoneal adhesions. One-third of surgeons surveyed use Veress needle insufflation in their surgical practices. More than 50% of respondents witnessed complications related to primary laparoscopic trocar insertion. CONCLUSION General surgeons in Canada use the open primary entry technique, with the Hasson trocar and cannula applied periumbilically to establish a pneumoperitoneum for laparoscopic surgery. This surgical approach is remarkably consistent nationally, although considerably variant across other surgical subspecialties. Peritoneal entry remains an important patient safety issue that requires ongoing evaluation and study to ensure translation into safe contemporary clinical practice.

Abstract
Ventral hernias, whether naturally occurring or the result of previous surgery, comprise one of the most common problems confronting general surgeons. As many as 25% of laparotomy incisions develop a hernia over long-term follow-up, which is a difficult problem with many treatment algorithms. Laparoscopic ventral hernia repair has improved over the last decade and has proven to be an effective treatment option. With fewer wound complications and low recurrence rates, it is a useful tool in the surgeon's armamentarium. Care should be taken regarding patient selection, operative technique, and mesh size to ensure adequate repair of the hernia, thereby preventing recurrence at a later date. The first attempt at a hernia repair has the highest chance of long-term success, so it is important that the surgeon take all the factors into mind before proceeding with operative repair.

Abstract
BACKGROUND AND OBJECTIVES To review the success and morbidity of laparoscopic major gynecologic surgery in patients with prior laparotomy bowel resection. METHODS Review of a prospective surgical database of all cases of laparoscopic major gynecologic surgery in patients with prior laparotomy bowel resection. No cases were excluded. Bowel diagnoses and procedures were total colectomy for inflammatory bowel disease (4), partial colectomy for colon cancer (6), partial small bowel resection for obstruction (1), and Whipple for pancreatic cancer (2). Two patients had 3 prior laparotomies, 8 patients had 2 prior laparotomies, and 3 patients had 1 prior laparotomy. All prior abdominal incisions were midline. Gynecologic diagnoses and procedures were laparoscopic cytoreduction for ovarian cancer (1), lsh/bso/staging for ovarian cancer (1), lavh/bso/lymphadenectomy for endometrial cancer (4), and lavh/bso, lsh/bso, or bso for large ovarian mass (7). Median patient age was 57 years, median BMI was 31kg/m(2), and all patients had medical comorbidities. RESULTS All 13 laparoscopic gynecologic surgeries were successful without trocar insertion injury, conversion to laparotomy, and without enterotomy. Abdominal adhesions were present in all cases. Median operative time was 2 hours, median blood loss was 100cc, and median hospital stay was 1 day. There were no postoperative complications. CONCLUSION Laparoscopic major gynecologic surgery in patients with prior laparotomy bowel resection is feasible for experienced laparoscopic surgeons.

Abstract
The umbilical ring easy kannula access appears to provide a safe portal of laparoscopic entry in pediatric patients with few complications. Background and Objectives: Standard techniques of laparoscopic access involve creating an abdominal wall defect and can result in complications. We describe the umbilical ring easy kannula access (UREKA) technique, evaluating safety and a decrease in complications related to port placement. Methods: UREKA is performed via a supra- or infraumbilical incision followed by circumferential dissection of the umbilical stalk. The umbilical skin is dissected free from the fascia, exposing the umbilical ring. Pneumoperitoneum is established either before or after placement of a dilating port through the open ring. We reviewed all laparoscopic procedures performed by one pediatric surgeon over 14 months using UREKA. Results: Ninety-four patients underwent laparoscopic surgery with initial port placement via UREKA. Appendectomy (n=57) was the most common procedure, followed by fundoplication (15) and cholecystectomy (10). No intestinal, solid organ, vascular, or bladder injuries related to port placement occurred. The only postoperative complication was a superficial wound infection in a 135-kg patient following cholecystectomy, treated successfully with oral antibiotics alone. Conclusion: The umbilical ring persists to some degree in all pediatric patients and provides a safe portal of entry for laparoscopic surgery. UREKA has few complications and is a straightforward, reproducible technique for gaining initial laparoscopic access.

Abstract
The aim of these recommendations of the French National College of Gynaecologists and Obstetricians was to focus the surgeon's attention on those aspects which could allow him/her to prevent, or at least limit, the incidence of these serious complications, in the absence of a previous laparotomy or specific risk factors (obesity, gauntness, large pelvic mass or pregnancy), four widely evaluated techniques can be used in a first line approach (Grade B): blind trans-umbilical technique following creation of pneumoperitoneum with a needle, open laparoscopy (Hasson technique), left upper quadrant entry (pneumoperitoneum and insertion of the first trocar) and direct trans-umbilical trocar with no prior pneumoperitoneum. The currently existing trials do not allow one or another of these techniques to be preferred. Radially expanding insertion systems and optical trocars cannot be recommended as a first-line approach, as a consequence of their currently insufficient degree of evaluation (Grade C). Trans-umbilical (blind or open) laparoscopic entry in a slim woman must be associated with care, as a result of the proximity of the large vessels (Grade B). If a blind trans-umbilical insertion technique is decided upon, one option can be to insufflate into the left upper quadrant (professional consensus). In the case of a previous midline laparotomy, whatever the technique used, initial entry is recommended at a distance from the scars (Grade B). It is recommended to carry out micro-laparoscopy in the LUQ, because this is the most completely evaluated technique for this indication (Grade C). One option is to use open laparoscopy at a distance from the existing scars (professional consensus). During pregnancy, the insertion position of the first laparoscopic trocar will need to be adapted according to the volume of the uterus (Grade B). Starting from 14WG, trans-umbilical Veress needle insufflation is contraindicated (Grade C). Two trocar insertion techniques are thus recommended: open laparoscopy (using the trans-umbilical or supra-umbilical routes, depending on the volume of the uterus) or micro-laparoscopy via the left upper quadrant (Grade C). After the second quarter of pregnancy, with laparoscopy the patient will need to be placed on a table inclined towards her left side, in order to minimize compression of the inferior vena cava (Grade B). In the case of laparoscopy during pregnancy, the insufflation pressure must be maintained at a maximum of 12mmHg (Grade B). After 24WG, if laparoscopy is performed, it is recommended to apply open laparoscopy, above the level of the umbilicus (professional consensus). Patients must be informed of the risks inherent to the insertion of trocars during laparoscopy (vascular, bowel or bladder injury) (Grade B). The more benign the pathology requiring an operation, the more detailed the supplied information must be, including that concerning rare but serious complications (Grade B).

Abstract
BACKGROUND AND OBJECTIVES Trocar insertion injury has a high morbidity, mortality, and cost. The purpose of this study was to compare standard trocar entry with our reduced-force closed trocar entry technique by measuring trocar insertion force using a mechanical force gauge. METHODS In the operating room, the force gauge was inserted into a sterile glove and connected to the proximal portion of the trocar to measure insertion force. Through one incision, we used a standard closed trocar entry, while through the other incision, we used our reduced-force closed trocar entry technique. After making the skin incision and before trocar entry, we spread and dilated the skin, subcutaneous tissue, fascia, and muscle with a hemostat. RESULTS Twenty-five patients entered the trial and none were excluded. Median trocar insertion force was 3.3lb (range, 1.6 to 5.4) with our reduced-force trocar entry technique versus 6.5lb (range, 2.0 to 14.0) with the standard trocar entry (P=.001). No complications occurred with the reduced-force trocar entry technique. CONCLUSION Our reduced-force trocar entry technique decreases trocar insertion force by 50%, requires no additional instruments or cost and is fast and safe. Reduced-entry force pressure may decrease the risk of trocar insertion injury.

Abstract
PURPOSE Different effects on cardiovascular and respiratory systems and liver are associated with pneumoperitoneum. This study aimed to determine the morphological changes in the abdominal anatomy as a result of increased intra-abdominal pressure due to pneumoperitoneum using MRI. METHODS Ten healthy female pigs were used in this study. MRI studies of the abdomen in supine position were made before the creation of pneumoperitoneum and 1 h after increasing the pressure to 14 mmHg. Changes in area, volume, and longitudinal and transverse length of the liver were measured. The diameters of the lumen of the abdominal aorta, the inferior vena cava and portal vein were observed in three positions along the abdominal cavity. The position of the diaphragm after the induction of pneumoperitoneum was also analyzed. RESULTS After induction of pneumoperitoneum, volume and transverse length of the liver was significantly increased, while peak area was decreased. Stenosis in the aortic lumen was observed (P < 0.05). Longitudinal and transverse diameters of the portal lumen were reduced, but significant differences were only found in the longitudinal diameter. Alterations in the diameter of the inferior vena cava lumen were obtained in three analyzed positions, but differences were significant only in two of them. A mean cranial displacement of the diaphragm equal to 25 mm was also observed. CONCLUSION Increasing abdominal pressure up to laparoscopic pressure (14 mmHg) provokes morphological changes in the liver, vascular structures and diaphragm. These changes could be related to functional alterations that different organs experience after the induction of pneumoperitoneum.

Abstract
OBJECTIVES To prospectively compare a novel type of valveless trocar that creates a curtain of pressurized carbon dioxide [CO(2)] gas (which maintains pneumoperitoneum at a lower gas flow rate) with standard trocars; to quantify the volume of CO(2) used; and to characterize CO(2) elimination during laparoscopic renal surgery. METHODS A total of 51 patients undergoing laparoscopic renal surgery by a single surgeon were prospectively evaluated using either the valveless trocar (n = 26) or standard trocars (n = 25). Patient demographics, operative time, volume of CO(2) gas consumed, CO(2) elimination, perioperative parameters, and postoperative complications were recorded and analyzed. RESULTS Both patient cohorts were comparable in their preoperative demographics, including body mass index, the number of patients with chronic obstructive pulmonary disease, and smoking history. Mean operative time was lower in the valveless trocar cohort (124.1 minutes) compared with the conventional trocar group (145.6 minutes), P = .047. Use of the valveless trocar was associated with a lower volume of intraoperative CO(2) consumed (120.0 ± 82.8 vs 300.6 ± 191.5; P < .001) and reduced CO(2) elimination compared with standard trocar use after the first 16 minutes of insufflation (P < .05). Minimal complications occurred, including 2 cases of subcutaneous emphysema in the valveless trocar group, and 1 case of respiratory acidosis in the conventional trocar group. CONCLUSIONS Use of a valveless trocar significantly reduced CO(2) consumption during transperitoneal laparoscopy. The valveless trocar also demonstrated significantly reduced CO(2) elimination and absorption when compared with the standard trocar.

Abstract
Laparoscopy is one of the most commonly performed procedures in the United States. Injury to a major retroperitoneal vessel occurs in 0.3% to 1.0% of procedures, most commonly during laparoscopic entry while placing the Veress needle or primary trocar. Fatal outcome can be related to massive gas embolism or exsanguination. Recommended treatment for gas embolism can range from supportive measures to external chest compression and insertion of a central line to withdraw gas from the right side of the heart. Recommended treatment of major vessel injury with massive hemorrhage consists of rapid laparotomy and control of hemorrhage using direct pressure until a surgeon experienced in vascular procedures arrives. When a major vessel injury occurs in a surgical facility distant from a medical center and without an available surgeon with vascular experience, based on the trauma literature, we recommend temporary control of blood loss using abdominal packing and closure (i.e., "damage control surgery") and judicious resuscitation (i.e., "damage control resuscitation") before transportation to a medical center.

Abstract
This study was carried out on apparently healthy adult non pregnant female Baladi goats to provide normal laparoscopic anatomy of the abdomen and to assess feasibility of laparoscopy for liver biopsy. Following preparation of animals, equipment and instruments, the primary port and laparoscope was placed on the umbilicus and 360° scan was performed for orientation and exploration of the abdominal cavity. Secondary ports were placed under direct laparoscopic observation to allow insertion of accessory instruments for tissue grasping, coagulation and severing. The obtained results cleared that ventral laparoscopic approach and tilting and rotating the animal during laparoscopic procedures provided better exposure of internal abdomen. Laparoscopy provided a comprehensive description of cranial and caudal abdominal regions. Laparoscopic liver biopsy required two secondary ports; one assisting port inserted in right subcostal area and one operating port inserted subxiphoid. The procedure was safe, practical and easily performed.

Abstract
OBJECTIVE To report our experience using Palmer's point entry in women undergoing gynecologic laparoscopic surgery. DESIGN Retrospective observational study. SETTING University teaching hospital, London, United Kingdom. PATIENT(S) We reviewed all patients who underwent laparoscopic gynecologic surgery under the care of the senior author between January 1, 2005, and December 31, 2008. INTERVENTION(S) Gynecologic laparoscopic surgery. MAIN OUTCOME MEASURE(S) Indications, incidence, success, and complications of using Palmer's entry. RESULT(S) Three hundred eighty-five patients underwent laparoscopic surgery. We used umbilical entry in 249 (64.6%) and Palmer's entry in 136 (35.4%). In almost three fourths of cases, the indications for using Palmer's point were previous laparotomy or the presence of large uterine fibroids. The next most common reasons for choosing Palmer's point were known documentation of intra-abdominal adhesions from prior laparoscopies, large ovarian cysts, and hernias or hernia repairs. Entry via Palmer's point was successful in all but two cases (98.5%), and there were no entry-related complications. CONCLUSION(S) Our experience shows that laparoscopic entry using the left upper quadrant is safe with a low failure rate. Because the vast majority of gynecologic laparoscopies are done using subumbilical entry, it seems that Palmer's entry is underused by many gynecologists, despite it being safer in patients at risk of underlying adhesions and more appropriate in the presence of a large pelvic mass or a nearby hernia.

Abstract
BACKGROUND Open or laparoscopic colorectal surgery comprises of many different types of procedures for various diseases. Depending upon the operation and modifiable and non-modifiable risk factors the intra- and postoperative morbidity and mortality rate vary. In general, surgical complications can be divided into intraoperative and postoperative complications and usually occur while the patient is still in the hospital. METHODS A literature search (1980-2009) was carried out, using MEDLINE, PubMed and the Cochrane library. RESULTS This review provides an overview how to identify and minimize intra- and postoperative complications. The improvement of different treatment strategies and technical inventions in the recent decade has been enormous. This is mainly attributable to the increase in the laparoscopic approach, which is now well accepted for many procedures. Training of the surgeon, hospital volume and learning curves are becoming increasingly more important to maximize patient safety, surgeon expertise and cost effectiveness. In addition, standardization of perioperative care is essential to minimize postoperative complications. CONCLUSION This review summarizes the main perioperative complications of colorectal surgery and influencable and non-influencable risk factors which are important to the general surgeon and the relevant specialist as well. In order to minimize or even avoid complications it is crucial to know these risk factors and strategies to prevent, treat or reduce intra- and postoperative complications.

Abstract
This article describes an exercise to investigate the utility of modeling and human factors analysis in understanding surgical processes and their vulnerabilities to medical error. A formal method to identify error vulnerabilities was developed and applied to a test case of Veress needle insertion during closed laparoscopy. A team of 2 surgeons, a medical assistant, and 3 engineers used hierarchical task analysis and Integrated DEFinition language 0 (IDEF0) modeling to create rich models of the processes used in initial port creation. Using terminology from a standardized human performance database, detailed task descriptions were written for 4 tasks executed in the process of inserting the Veress needle. Key terms from the descriptions were used to extract from the database generic errors that could occur. Task descriptions with potential errors were translated back into surgical terminology. Referring to the process models and task descriptions, the team used a modified failure modes and effects analysis (FMEA) to consider each potential error for its probability of occurrence, its consequences if it should occur and be undetected, and its probability of detection. The resulting likely and consequential errors were prioritized for intervention. A literature-based validation study confirmed the significance of the top error vulnerabilities identified using the method. Ongoing work includes design and evaluation of procedures to correct the identified vulnerabilities and improvements to the modeling and vulnerability identification methods.

Abstract
INTRODUCTION Laparoscopic trocars typically maintain pneumoperitoneum using trap door valves and silicone seals. However, valves and seals hinder passage of instruments, cause lens smudging, trap specimens and needles being removed from the abdominal cavity, and lose their seal with repeated instrument exchange. AIM The aim of the present study was to evaluate the feasibility of a newly designed valve-less trocar. METHODS The valve-less trocar system creates a curtain of forced gas to maintain pneumoperitoneum. A separate unit filters smoke and recirculates captured escaping gas. The valve-less trocar was trialed in consecutive laparoscopic renal procedures of a single surgeon. Perioperative parameters and outcomes were collected and analyzed. The system's safety, advantages, and disadvantages were evaluated. Insufflation gas usage, elimination, and absorption were also measured. RESULTS Twenty-five patients underwent laparoscopic renal procedures using the valve-less trocar system. The procedures included laparoscopic partial, radical, and donor nephrectomy. The mean patient age was 58.26 years. The mean operative time was 125 minutes and the mean drop in Hb for the cohort was 2.34 g/dL (range 0.4-5.4). Two patients developed subcutaneous emphysema and of the two patients, one developed clinically insignificant pneumomediastinum postoperatively. There were no postoperative complications. The surgeon noted that the use of a valve-less trocar decreased smudging of laparoscopes, expeditiously evacuated smoke during cauterization leading to improved visualization, maintained pneumoperitoneum even while suctioning, and resulted in easy extraction of specimens and needles. It was noted that insufflation gas consumption was low and CO(2) elimination was not impaired. CONCLUSION Use of a valve-less trocar is safe. Decreased laparoscope smudging may translate into decreased operative times and reduced gas consumption may equate to cost savings. Additionally, its use brings several advantages and convenience to the operating surgeon. However, the system should be compared with conventional trocars prospectively to demonstrate clinical and economic benefit.

Left upper quadrant laparoscopic placement: effects of insertion angle and body mass index on distance to posterior peritoneum by magnetic resonance imaging. Am J Obstet Gynecol 2009; 201:522.e1-5.

Abstract
OBJECTIVE To determine the ideal angle for insertion of laparoscopic instruments at Palmer's point. STUDY DESIGN Abdominal magnetic resonance images were reviewed for 75 women between ages 18 and 50 years old. The distance from the skin to the retroperitoneal structures were determined perpendicular to the spine and angled 45 degrees caudally. RESULTS When instruments are inserted perpendicular to the skin in the axial plane and peritoneum perpendicular to the spine, the distance from skin to posterior was 10.0 +/- 0.2 cm and to the aorta was 11.3 +/- 0.2 cm. If instruments are inserted at an angle 45 degrees caudally, this distance increased to 16.6 +/- 0.2 cm. CONCLUSION When inserting laparoscopic instruments at Palmer's point, insertion perpendicular to the skin in the axial plane and angled 45 degrees caudally in relation to the spine offers an increased margin of safety compared with insertion perpendicular to the spine, particularly in thin women.

Abstract
The aim of the study was to describe the morbidity and mortality of gynaecological laparoscopy in a pilot center of Cameroon. It was a monocentric retrospective study over a period of seven years. All files of patients who had laparoscopic surgery in the service were reviewed. Files with incomplete information were excluded. Complications were defined as an event that had modified the usual cause of the procedure or of the postoperative period. They were classified as surgical complications (during insertion of Veress needle and trocarts, intraoperative and postoperative complications) also reorganised as major and minor complications and anaesthetic complications. The rate of laparoconconversion was noted. The data of 609 patients was gathered and examined. Their mean age was 31.57 (19-63years). The mean parity and gestity was 0.77 and 1.82, respectively. The common findings in their past history were sexually transmitted infection (39.9%), criminal abortions (35.03%) and previous surgery (39.1%). Infertility was the main indication of the surgery (76.3%) followed by postmyomectomy adhesiolysis (15%). The main operative findings were adhesions (78.16%). The mortality rate is 0.16%. The surgical morbidity rate is 2.46% with 0.99% of complications during insertion of Veress needle and trocarts and 1.48% during surgery. Among these complications, 1.8% were minor complications and 0.66%, major ones. Five patients had complications due to anaesthesia (0.82%). Postoperative complications (8.3%) were of low gravity and were mainly digestive, infectious and moderate vaginal bleeding. The rate of laparoconversion was 2.46%, mainly due to difficulties during surgery. This study shows that operative gynaecologic laparoscopy is associated with acceptable mortality and morbidity rate in our milieu.

Abstract
Peritoneal access and creation of pneumoperitoneum are the key initial steps of laparoscopic surgery. This is commonly achieved by either introducing Veress needle or by gradual dissection of all the layers of the abdominal wall and then introducing a port under direct vision. The two techniques are extremely safe, but large outcome studies have found slightly increased complications with the Veress needle. Randomized trials do not support such finding and both techniques continue to have their enthusiasts. We hereby describe an open method of initial port placement, wherein the port is introduced through the umbilical cicatrix under direct vision.

Abstract
Abdominal wall bleeding may complicate any laparoscopic procedure. Piercing or laceration of vessels transversing the abdominal wall during trocar placement is generally the cause. Bleeding may occur at the very beginning of the surgery but, in some cases, it may go unrecognized for a while complicating the operation and the postoperative course. Planned and careful trocar placement can prevent most of these instances that otherwise can be readily managed avoiding severe morbidity.
