Remains of the day: Biliary complications related to single-port laparoscopic cholecystectomy  

PubMed Central

AIM: To assesse the rate of bile duct injuries (BDI) and overall biliary complications during single-port laparoscopic cholecystectomy (SPLC) compared to conventional laparoscopic cholecystectomy (CLC). METHODS: SPLC has recently been proposed as an innovative surgical approach for gallbladder surgery. So far, its safety with respect to bile duct injuries has not been specifically evaluated. A systematic review of the literature published between January 1990 and November 2012 was performed. Randomized controlled trials (RCT) comparing SPLC versus CLC reporting BDI rate and overall biliary complications were included. The quality of RCT was assessed using the Jadad score. Analysis was made by performing a meta-analysis, using Review Manager 5.2. This study was based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. A retrospective study including all retrospective reports on SPLC was also performed alongside. RESULTS: From 496 publications, 11 RCT including 898 patients were selected for meta-analysis. No studies were rated as high quality (Jadad score ? 4). Operative indications included benign gallbladder disease operated in an elective setting in all studies, excluding all emergency cases and acute cholecystitis. The median follow-up was 1 mo (range 0.03-18 mo). The incidence of BDI was 0.4% for SPLC and 0% for CLC; the difference was not statistically different (P = 0.36). The incidence of overall biliary complication was 1.6% for SPLC and 0.5% for CLC, the difference did not reached statistically significance (P = 0.21, 95%CI: 0.66-15). Sixty non-randomized trials including 3599 patients were also analysed. The incidence of BDI reported then was 0.7%. CONCLUSION: The safety of SPLC cannot be assumed, based on the current evidence. Hence, this new technology cannot be recommended as standard technique for laparoscopic cholecystectomy. PMID:24574757

Compressive hematoma due to pseudoaneurysm of the right hepatic artery: a rare cause of obstructive jaundice after single-port cholecystectomy.  

PubMed

Single-port laparoscopic cholecystectomy is considered as a form of natural orifice surgery with better esthetic outcomes than traditional laparoscopic cholecystectomy. It is a technically demanding procedure, and no adequately powered trial has assessed the safety of this technique. Vascular injuries are less common than bile duct injuries during this procedure, but they can be rapidly fatal. The development of a right hepatic artery pseudoaneurysm is a rare but serious complication associated with single-port laparoscopic cholecystectomy. Two weeks following a single-port laparoscopic cholecystectomy for angiocholitis, a 40-year-old male patient presented with obstructive jaundice and persistent abdominal pain. The diagnosis of compressive hematoma due to a ruptured right hepatic artery pseudoaneurysm was confirmed by computed tomography scan and angiography. It was successfully treated by selective embolization of the right hepatic artery. In our experience, endovascular management was a noninvasive and effective treatment of ruptured pseudoaneurysms.

Single port laparoscopic right hemicolectomy for ileocolic intussusception  

PubMed Central

A 36-year-old male was admitted with right lower abdominal pain and diarrhea for more than 3 mo. Colonoscopy and a barium enema study revealed a submucosal tumor over the cecum, but computed tomography showed an ileal lipoma. There was no definitive diagnosis preoperatively, but ileocolic intussusception was noted during surgery. Single port laparoscopic radical right hemicolectomy was performed because intra-operative reduction failed. The histological diagnosis of the resected tumor was lipoma. Single port laparoscopic surgery has recently been proven to be safe and feasible. There are advantages compared with conventional laparoscopic surgery, such as smaller incision wounds, fewer port site complications, and easier conversion. However, there are some drawbacks which need to be overcome, such as difficulties in triangulation and instrument clashing. If there are no contraindications to laparoscopy, single port laparoscopic surgery can be performed safely and should be considered for diagnosis and treatment of intussusception in adults. Here, we report the first case of ileocolic intussusception successfully treated by single port laparoscopic surgery. PMID:23538552

Appraisal of laparoscopic cholecystectomy.  

PubMed Central

This paper reports the experience of three general surgeons performing 304 laparoscopic cholecystectomies in three private hospitals between October 1989 and November 1990. Laparoscopic cholecystectomy boasts two major advantages over the conventional procedure: the remarkable reduction in postoperative pain and economic benefit, largely due to the patient's early return to work. Revealing a complication rate of 2% and no deaths, this study has shown that this procedure can offer patients these advantages with a medical risk no greater than that accompanying conventional cholecystectomy. Patient safety must be paramount, and it is the responsibility of the surgical community to ensure that all surgeons receive the highest quality training and that the technique is applied appropriately.

Ruptured Spleen Following Laparoscopic Cholecystectomy  

PubMed Central

Background: Laparoscopic cholecystectomy is generally a safe and well-accepted procedure. However, in a small percentage of patients, it is associated with complications, such as bleeding and injury to the bile duct and other viscera. Splenic injury as a result of laparoscopic surgery has been reported only in the context of direct trauma, for example due to retraction in hand-assisted urologic surgery. To date, there have been no reported cases of patients requiring splenectomy following laparoscopic cholecystectomy. We report an unusual case of ruptured spleen presenting less than 28 days following “uncomplicated” laparoscopic cholecystectomy. Results: A 52-year-old female presented to our Accident and Emergency department 3 weeks following “uncomplicated” laparoscopic cholecystectomy, complaining of severe left upper quadrant pain radiating to the left shoulder tip. Clinical examination revealed a patient in hypovolemic shock, with localized left upper quadrant peritonism. Abdominal computed tomography supported a diagnosis of splenic rupture, and the patient required an emergency splenectomy. Discussion: Splenic injury rarely complicates laparoscopic cholecystectomy. We postulate that either congenital or posttraumatic adhesions of the parietal peritoneum to the spleen may have caused the capsule to tear away from the spleen when the pneumoperitoneum was established, resulting in subcapsular hematoma and subsequent rupture in this patient. Videoscopic assessment of the spleen at the end of laparoscopic cholecystectomy might be a worthwhile exercise to aid early recognition and management in such cases. PMID:17651581

Single-Port Laparoscopic Surgery for Inflammatory Bowel Disease  

PubMed Central

Background. Single Port Laparoscopic Surgery (SPLS) is being increasingly employed in colorectal surgery for benign and malignant diseases. The particular role for SPLS in inflammatory bowel disease (IBD) has not been determined yet. In this review article we summarize technical aspects and short term results of SPLS resections in patients with Crohn's disease or ulcerative colitis. Methods. A systematic review of the literature until January 2012 was performed. Publications were assessed for operative techniques, equipment, surgical results, hospital stay, and readmissions. Results. 34 articles, published between 2010 and 2012, were identified reporting on 301 patients with IBD that underwent surgical treatment in SPLS technique. Surgical procedures included ileocolic resections, sigmoid resections, colectomies with end ileostomy or ileorectal anastomosis, and restorative proctocolectomies with ileum-pouch reconstruction. There was a wide variety in the surgical technique and the employed equipment. The overall complication profile was similar to reports on standard laparoscopic surgery in IBD. Conclusions. In experienced hands, single port laparoscopic surgery appears to be feasible and safe for the surgical treatment of selected patients with IBD. However, evidence from prospective randomized trials is required in order to clarify whether there is a further benefit apart from the avoidance of additional trocar incisions. PMID:22619710

Laparoscopic single port surgery nephrectomy in a child – initial experience  

PubMed Central

The aim of the stucdy was to present technical aspects and possible intraoperative complications based on the first single port surgery (SPS) laparoscopic nephrectomy performed in our center. The SPS laparoscopic nephrectomy of the right kidney was performed using a transperitoneal access in a 4-year-old child due to a small nonfunctional kidney complicated by hypertension. The intraoperative course was complicated by rupture of the gall bladder wall after grasper removal without leakage of its contents into the peritoneal cavity. No postoperative complications occurred. The SPS nephrectomy appears to be an advantageous method in children which offers a good cosmetic effect. Other benefits require confirmation in further studies. Fixation of the gall bladder is a very helpful but risky maneuver. PMID:23362432

Single Incision Laparoscopic Total Gastrectomy and D2 Lymph Node Dissection for Gastric Cancer Using a Four-Access Single Port: The First Experience  

PubMed Central

Single incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES) have been developed to reduce the invasiveness of laparoscopic surgery. SILS has been frequently applied in various clinical settings, such as cholecystectomy, colectomy, and sleeve gastrectomy. So far, there have been four reports on single incision laparoscopic distal gastrectomy and one report on single incision laparoscopic total gastrectomy with D1 lymph node dissection for gastric cancer. In this report, we present our single incision laparoscopic total gastrectomy with D2 lymph node dissection technique using a four-hole single port (OctoPort) in a patient with gastric cancer.

Initial experience of single port laparoscopic totally extraperitoneal hernia repair: nearly-scarless inguinal hernia repair  

PubMed Central

Purpose In the early 1990's laparoscopic hernioplasty gained popularity worldwide. Thereafter, laparoscopic surgeons have attempted to improve cosmesis using single port surgery. This study aims to introduce and assess the safety and feasibility of single port laparoscopic total extraperitoneal (TEP) hernia repair with a nearly-scarless umbilical incision. Methods Sixty three single port laparoscopic TEP hernia repairs were performed in sixty patients from June 2010 to March 2011 at Incheon St. Mary's Hospital, with the use of a glove single-port device and standard laparoscopic instruments. Demographic and clinical data, intraoperative findings, and postoperative course were reviewed. Results Of the 63 hernias treated, 31 were right inguinal hernias, 26 were left inguinal hernias and 3 were both inguinal hernias. There was one conversion to conventional three port laparoscopic transabdominal preperitoneal hernioplasty. Mean operative time was 62 minutes (range, 32 to 150 minutes). There were no intraoperative complications. Postoperative complications occurred in two cases (wound seroma and urinary retension) and were successfully treated conservatively. Mean hospital stay was 2.15 days. Conclusion Single port laparoscopic TEP hernia repair is safe and feasible. Umbilical incision provides an excellent cosmetic outcome. Prospective randomized studies comparing single port and conventional three port laparoscopic TEP repairs with short-term outcome and long-term recurrence rate are needed for confirmation.

Contraindications and complications of laparoscopic cholecystectomy.  

PubMed

Laparoscopic cholecystectomy is a commonly performed procedure for the removal of symptomatic gallstones. Compared with open cholecystectomy, laparoscopic cholecystectomy is associated with less postoperative pain, earlier discharge from the hospital and a more rapid recovery. However, there are specific contraindications to the procedure, including empyema of the gallbladder, gangrenous cholecystitis, coagulopathy, portal hypertension and peritonitis. Complications from laparoscopic cholecystectomy include common duct injury, bleeding, bile leakage and wound infection. An understanding of these issues allows the family physician to more appropriately select patients for laparoscopic removal of the gallbladder. PMID:7977000

Laparoscopic Cholecystectomy in Cirrhotic Patients  

PubMed Central

Background and Objectives: Gallstones are twice as common in cirrhotic patients as in the general population. Although laparoscopic cholecystectomy (LC) has become the gold standard for symptomatic gallstones, cirrhosis has been considered an absolute or relative contraindication. Many authors have reported on the safety of LC in cirrhotic patients. We reviewed our patients retrospectively and assessed the safety of LC in cirrhotic patients at a tertiary care hospital in Pakistan. Methods: From January 2003 to December 2005, a retrospective study was conducted at SU IV, Liaquat University of Medical & Health Sciences Jamshoro. All the cirrhotic patients with Child-Pugh class A and B cirrhosis undergoing LC were included in the study. Cirrhosis was diagnosed based on clinical, biochemical, ultrasonography, and intraoperative findings of the nodular liver and histopathological study. Results: Of 250 patients undergoing laparoscopic cholecystectomy, 20 (12.5%) were cirrhotic. Of these 20, 12 (60%) were Childs group A and 8 (40%) were group B. Thirty percent were hepatitis B positive, and 70% were hepatitis C positive. Preoperative diagnosis of cirrhosis was possible in 80% of cases, and 20% were diagnosed during surgery. Morbidity rate was 15% and mortality rate was 0%. Two patients developed postoperative ascites, and mean hospital stay was 2.8±0.1 days. Of the 20 cases, 2 (10%) were converted to open cholecystectomy. The mean operation time was 70.2±32.54 minutes. Conclusion: Laparoscopic cholecystectomy is an effective and safe treatment for symptomatic gallstone disease in select patients with Child-Pugh A and B cirrhosis. The advantages over open cholecystectomy are the lower morbidity rate and reduced hospital stay. PMID:20202403

Laparoscopic vaginal vault closure with conventional straight instruments in single-port access total laparoscopic hysterectomy  

PubMed Central

Objective Laparoscopic vaginal vault closure with conventional straight instruments is the final barrier to single-port access total laparoscopic hysterectomy (SPA-TLH). The aim of this study is to find out the safer, easier, simpler, faster, and even cheaper way to overcome it. Methods Vaginal vault suturing techniques of 152 consecutive single-port access total laparoscopic hysterectomy cases performed by the author in Gangnam CHA Hospital, CHA University from October 1, 2003 to June 30, 2012, were retrospectively analysed with medical records and DVDs. Results Of 152 patients who were attempted SPA-TLH, 119 patients (78%) were finished their operations without conversion to multi-port laparoscopy or laparotomy. Of women with successful SPA-TLH, 8 cases (7%) were closed their vaginal vaults vaginally (median, 20 minutes; range, 15-44 minutes), and 111 cases (93%) laparoscopically (median, 44 minutes; range, 13-56 minutes). Laparoscopic vault closure techniques were continuous suture (4 cases, 3%; median, 36 minutes; range, 30-45 minutes), interrupted sutures using knot-pusher (7 cases, 6%; median, 52 minutes; range, 48-56 minutes) Endo Stitch suture (2 cases, 2%; median, 32 minutes; range, 13-50 minutes), continuous vault closure using percutaneous sling sutures (PCSS) (92 cases, 77%; median, 40 minutes; range, 19-56 minutes), and continuous vault closure without PCSS (6 cases, 5%; median, 23 minutes; range, 16-31 minutes). Conclusion Laparoscopic vault closure using PCSS in SPA-TLH only with conventional straight instruments is the best way to overcome the barrier and the short-cut to shorten the learning curve to date.

Is cirrhosis a contraindication to laparoscopic cholecystectomy?  

PubMed

Laparoscopic cholecystectomy is the gold standard treatment for the vast majority of patients with symptomatic cholelithiasis. Although cirrhotic patients are twice as likely to develop gallstones as compared with noncirrhotic patients, cirrhosis has historically been considered a relative, if not absolute, contraindication to laparoscopic cholecystectomy. More recently a number of authors have reported on the safety of laparoscopic cholecystectomy in cirrhotic patients. We reviewed our patients retrospectively and assessed the safety of laparoscopic cholecystectomy in cirrhotic patients as compared with noncirrhotics at a large liver transplant center. A retrospective longitudinal cohort study was conducted of all laparoscopic cholecystectomies performed by our surgical group between August 2002 and April 2011. Of 63 patients undergoing laparoscopic cholecystectomy, 32 (51%) were cirrhotic. Of the 30 for whom a Child score could be calculated, 11 (34%) were Child A, 14 (44%) were Child B, and five (16%) were Child C. The morbidity rate was 33 per cent and mortality rate was 2 per cent. Length of stay, conversion rates, 30-day readmission rates, and morbidity and mortality rates were not significantly different between the cirrhotic and noncirrhotic groups. There was a trend toward higher complication rates in Child C cirrhotics. Our results indicate that laparoscopic cholecystectomy can be performed with acceptable morbidity and mortality in carefully selected cirrhotic patients. PMID:25569066

Single-Port Access Laparoscopic Hysterectomy: A New Dimension of Minimally Invasive Surgery  

PubMed Central

The fundamental idea is to have all of the laparoscopic working ports entering the abdominal wall through the same incision. Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus and reduces morbidity of minimally invasive surgery. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. This review summarizes the history of SPAL hysterectomy (single-port access laparoscopy), and emphasizes nomenclature, surgical technique, instrumentation, and perioperative outcomes. Specific gynecological applications of single-port hysterectomy to date are summarized. Using the PubMed database, the English-language literature was reviewed for the past 40 years. Keyword searches included scarless, scar free, single-port/trocar/incision, single-port access laparoscopic hysterectomy. Within the bibliography of selected references, additional sources were retrieved. The purpose of the present article was to review the development and current status of SPAL hysterectomy and highlight important advances associated with this innovative approach. PMID:22442528

Laparoscopic female sterilisation by a single port through monitor--a better alternative.  

PubMed

Female sterilisation by tubal occlusion method by laparocator is most widely used and accepted technique of all family planning measures all over the world. After the development of laparoscopic surgery in all faculties of surgery by monitor, now laparoscopic female sterilisation has been developed to do under monitor control by two ports--one for laparoscope and second for ring applicator. But the technique has been modified using single port with monitor through laparocator in which camera is fitted on the eye piece of laparocator (the same laparocator which is commonly used in camps without monitor since a long time in India). In this study over a period of about 2 years, a total 2011 cases were operated upon. In this study, I used camera and monitor through a single port by laparocator to visualise as well as to apply ring on fallopian tubes. The result is excellent and is a better alternative to conventional laparoscopic sterilisation and double puncture technique through camera--which give two scars and an extra assistant is required. However, there was no failure and the strain on surgeon's eye was minimum. Single port is much easier, safe, equally effective and better acceptable method. PMID:22187798

Single port laparoscopic long-term tube gastrostomy in Göttingen minipigs.  

PubMed

Oral dosing by gavage is often used to test compounds in minipigs. This method is also used for certain nutritional studies that require exact dosing. This procedure may be stressful for the animal and requires the assistance of more than one technician. We investigated whether a gastrostomy tube could be placed and maintained in Göttingen minipigs using a single port laparoscopic technique. As part of another study, laparoscopic gastrostomy tube placement was performed in 12 Göttingen minipigs (32?±?2?kg) under general anesthesia. The procedure involved single port laparoscopic visualization of the stomach and placement of a locking pigtail catheter into the fundus region of the stomach. The minipigs were followed for three weeks after surgery and macroscopic and microscopic tissue reactions were evaluated at necropsy. All catheters were successfully placed and were easy to use. At necropsy it was evident that the catheter had entered the stomach in the fundus region in 11/12 of the animals. In one animal the catheter had entered the antrum region. None of the animals developed leakage or clinically detectable reactions to the gastrostomy tube. Histopathologically, only discrete changes were observed. Single port laparoscopic tube gastrostomy with a locking pigtail catheter is safe, simple and reliable and is an appropriate alternative to, for example, percutaneous endoscopic gastrostomy, when long-term enteral delivery of pharmacological or nutritional compounds is needed. The use of the gastrostomy tube was easy and, based on subjective assessment, feeding was minimally stressful to the animals. PMID:25480656

Transumbilical single port laparoscopic appendectomy using basic equipment: a comparison with the three ports method  

PubMed Central

Purpose Single port laparoscopic surgery is a rapidly evolving laparoscopic surgical approach. We report a comparison of transumbilical single port laparoscopic appendectomy (TUSPLA) and conventional laparoscopic appendectomy (CLA) in a Korean military hospital. Methods This single-center retrospective study of 63 patients who received laparoscopic appendectomy was conducted between May 2011 and October 2011. Nineteen patients received TUSPLA and 44 patients received CLA. Clinical outcomes such as operation time, hospital stay, postoperative pain, diet, and postoperative complication were reviewed. Results There were no statistically significant differences between TUSPLA and CLA patients, respectively, in operation time (58.9 minutes vs. 52.3 minutes, P = 0.262), duration of hospitalization (10.2 days vs. 10.6 days, P = 0.782), mean visual analogue scale score (2.6 vs. 2.5, P = 0.894), and return to diet (1.6 days vs. 1.7 days, P = 0.776). There were two cases (10.5%) of short-term complications in the TUSPLA group and four cases (9.1%) of short-term complications in the CLA group. All patients were fully recovered at discharge. Conclusion TUSPLA is a feasible alternative for CLA. When a glove port is used, no special instruments are needed. Thus, it can be performed in a hospital equipped with basic laparoscopic surgical instruments. PMID:23091793

Single-port laparoscopic cryptorchidectomy in dogs and cats: 25 cases (2009-2014).  

PubMed

Objective-To describe the operative technique for single-port laparoscopic cryptorchidectomy (SPLC) in dogs and cats and evaluate clinical outcome for patients that underwent the procedure. Design-Retrospective case series. Animals-25 client-owned dogs (n = 22) and cats (3). Procedures-Dogs and cats that underwent SPLC with 3 commercially available single-port devices between 2009 and 2014 were retrospectively identified through a multi-institutional medical records review. Surgery was performed via a single-port device placed through a 1.5- to 3.0-cm abdominal incision either at the region of the umbilicus or caudal to the right 13th rib. The cryptorchidectomy was performed with graspers, a bipolar vessel sealing device, and a 30° telescope. Results-SPLC was performed with a single-incision laparoscopic surgery port (n = 15), a multitrocar wound-retractor access system (8), or a metal resterilizable single-port access device (2). Median age was 365 days (range, 166 to 3,285 days). Median body weight was 18.9 kg (41.6 lb; range, 1.3 to 70 kg [2.9 to 154 lb]). Median surgical time was 38 minutes (range, 15 to 70 minutes). Thirty-two testes were removed (12 left, 6 right, and 7 bilateral). Four patients had 1 additional abdominal surgical procedure performed concurrently during SPLC. No intraoperative or postoperative complications were encountered. Conclusions and Clinical Relevance-Results suggested that SPLC can be performed in a wide range of dogs and cats with cryptorchidism and can be combined with other elective laparoscopic surgical procedures. The SPLC technique was associated with a low morbidity rate and provided a potentially less invasive alternative to traditional open and multiport laparoscopic techniques. PMID:25406705

Ureteral Obstruction Swine Model through Laparoscopy and Single Port for Training on Laparoscopic Pyeloplasty  

PubMed Central

This study aims firstly to assess the most adequate surgical approach for the creation of an ureteropelvic juntion obstruction (UPJO) animal model, and secondly to validate this model for laparoscopic pyeloplasty training among urologists. Thirty six Large White pigs (28.29±5.48 Kg) were used. The left ureteropelvic junction was occluded by means of an endoclip. According to the surgical approach for model creation, pigs were randomized into: laparoscopic conventional surgery (LAP) or single port surgery (LSP). Each group was further divided into transperitoneal (+T) or retroperitoneal (+R) approach. Time needed for access, surgical field preparation, wound closure, and total surgical times were registered. Social behavior, tenderness to the touch and wound inflammation were evaluated in the early postoperative period. After ten days, all animals underwent an Anderson-Hynes pyeloplasty carried out by 9 urologists, who subsequently assessed the model by means of a subjective validation questionnaire. Total operative time was significantly greater in LSP+R (p=0.001). Tenderness to the touch was significantly increased in both retroperitoneal approaches, (p=0.0001). Surgeons rated the UPJO porcine model for training on laparoscopic pyeloplasty with high or very high scores, all above 4 on a 1-5 point Likert scale. Our UPJO animal model is useful for laparoscopic pyeloplasty training. The model created by retroperitoneal single port approach presented the best score in the subjective evaluation, whereas, as a whole, transabdominal laparoscopic approach was preferred.

Overview of single-port laparoscopic surgery for colorectal cancers: Past, present, and the future  

PubMed Central

Single-port laparoscopic surgery (SPLS) is implemented through a tailored minimal single incision through which a number of laparoscopic instruments access. Introduction of operation-customized port system, utilization of a camera without a separate external light, and instruments with different lengths has brought the favorable environment for SPLS. However, performing SPLS still creates several hardships compared to multiport laparoscopic surgery; a single-port system inevitably leads to clashing of surgical instruments due to crowding. To overcome such difficulties, investigators has developed novel concepts and maneuvers, including the concept of inverse triangulation and the maneuvers of pivoting, spreading out dissection, hanging suture, and transluminal traction. The final destination of SPLS is expected to be a completely seamless operation, maximizing the minimal invasiveness. Specimen extraction through the umbilicus can undermine cosmesis by inducing a larger incision. Therefore, hybrid laparoscopic technique, which combined laparoscopic surgical technique with natural orifice specimen extraction (NOSE) - i.e., transvaginal or transanal route-, has been developed. SPLS and NOSE seemed to be the best combination in pursuit of minimal invasiveness. In the near future, robotic SPLS with natural orifice transluminal endoscopic surgery’s way of specimen extraction seems to be pursued. It is expected to provide a completely or nearly complete seamless operation regardless of location of the lesion in the abdomen. PMID:24574772

Single port laparoscopic appendectomy in children using glove port and conventional rigid instruments  

PubMed Central

Purpose To further improve the advantages of minimally invasive surgery, single port laparoscopic techniques continue to be developed. We report our initial experience with single port laparoscopic appendectomy (SPLA) in children and compare its outcomes to those of conventional laparoscopic appendectomy (CLA). Methods Clinical data were prospectively collected for SPLA cases performed at Chung-Ang University Hospital by a single surgeon between March 2011 and December 2011, including operative time, perioperative complications, conversion rate, and length of hospital stay. Each case of SPLA was performed using conventional laparoscopic instruments through Glove port placed into the single umbilical incision. To compare outcomes, a retrospective review was performed for those patients who underwent CLA between March 2010 and December 2010. Results Thirty-one patients underwent SPLA and 114 patients underwent CLA. Mean age (10.5 years vs. 11.1 years, P = 0.43), weight (48.2 kg vs. 42.9 kg, P = 0.27), and operation time (41.8 minutes vs. 37.9 minutes, P = 0.190) were comparable between both groups. Mean hospital stay was longer for CLA group (2.6 days vs. 3.7 days, P = 0.013). There was no conversion to conventional laparoscopic surgery in SPLA group. In CLA group, there were nine complications (7.9%) with 3 cases of postoperative ileuses and 6 cases wound problems. There was one complication (3.2%) of umbilical surgical site infection in SPLA group (P = 0.325). Conclusion The results of this study demonstrated that SPLA using conventional laparoscopic instruments is technically feasible and safe in children. SPLA using conventional laparoscopic instruments might be popularized by eliminating the need for specially designed instruments. PMID:24761405

Background Laparoscopic surgery has become the preferred approach for many procedures because of reduced post-operative pain, better recovery, shorter hospital stay and improved cosmesis. Single incision laparoscopic surgery is one of the many recent variants where either standard ports or a specially designed single multi-channel port is introduced through a single skin incision. While the cosmetic advantage of this is obvious, the evidence base for claims of reduced morbidity and better post-operative recovery is weak. This study aims to compare the effectiveness of single port/incision laparoscopic appendicectomy with standard three-port laparoscopic appendicectomy in adult patients at six weeks post-surgery. We also wish to assess the feasibility of a multicentre randomised controlled trial comparing single port/incision laparoscopic surgery with standard three-port laparoscopic surgery for other surgical techniques. Methods and design Patients diagnosed with suspected appendicitis and requiring surgical treatment will be randomised to receive either standard three-port or single incision laparoscopic surgery. Data will be collected from clinical notes, operation notes and patient reported questionnaires. The following outcomes will be considered: 1. Effectiveness of the surgical procedure in terms of: •patient reported outcomes •clinical outcomes •resource use 2. Feasibility of conducting a randomised controlled trial (RCT) in the emergency surgical setting by quantifying: •patient eligibility •randomisation acceptability •feasibility of blinding participants to the intervention received •completion rates of case report forms and patient reported questionnaires Trial registration ISRCTN66443895 (assigned 10 March 2011, first patient randomised 09 January 2011) PMID:23111090

[Conversions and reinterventions in laparoscopic cholecystectomy].  

PubMed

From the introduction of the laparoscopy in our clinic, more and more of the cholecystectomies, reaching over 50% are done by this technique. Based upon the accumulation of an already important experience, the paper tries to analyze the situations in which, during or after laparoscopic cholecystectomy, intraoperative conversions (deliberate or of necessity) or reinterventions were necessary. We present a global view of the number of these cases and also (an in detail) analysis of the causes the imposed such decisions and of the solutions adopted. The percentages of 5.55 conversions and 1.49 reinterventions seem reasonable and acceptable in comparison with the initial results published by some experience surgeons in the field of laparoscopic surgery.

Laparoscopic cholecystectomy using 2-mm instruments.  

PubMed

Today, laparoscopic cholecystectomy is the method of choice for treatment of symptomatic gallbladder disorders. It minimizes effects of the operation that are independent of the gallbladder, such as trauma to the abdominal wall and other soft tissue. The surgical wounds were even smaller when 2-mm trocars were used. Laparoscopic cholecystectomy using 2-mm instruments was performed in a consecutive series of 14 patients with symptomatic gallstones. The procedure was completed in 12 cases, with conversion to open surgery in two cases. Intraoperative cholangiography was always performed. The postoperative course was always uneventful. The cosmetic effect was highly satisfactory. The procedure using 2-mm instruments could be indicated in selected patients with uncomplicated gallstone disease. PMID:9820716

Is a Drain Required after Laparoscopic Cholecystectomy?  

PubMed Central

Objective: Whether drains should be routinely used after laparoscopic cholecystectomy is still debated. We aimed to retrospectively evaluate the benefits of drain use after laparoscopic cholecystectomy for non-acute and non-inflamed gallbladders. Materials and Methods: Two hundred and fifty patients (mean age, 47±13.8 years; 200 females and 50 males) who underwent laparoscopic cholecystectomy for cholestasis were included in the study. The medical files of the patients were examined retrospectively to obtain data on patient demographics, cholecystitis attacks, complications during the operation, whether a drain was placed in the biliary tract during the operation, etc. The volume of the fluid collection detected in the subhepatic area by ultrasonography on the first postoperative day was recorded. Results: Drains were placed in 51 patients (20.4%). The mean duration of drain placement was 3.1±1.9 (range 1–16) days. Fluid collection was detected in the gallbladder area in 67 patients (26.8%). The mean volume of collected fluid was 8.8±5.2 mL. There were no significant effects of age, gender, and previous cholecystitis attacks on the presence or volume of the fluid collection (P>0.05 for all). With regard to the relationship between fluid collection and drains, 52 of 199 (26.1%) patients without drains had postoperative fluid collection, compared to 15 of 51 (29.4%) patients with drains (P>0.05). Conclusion: In conclusion, there is no relationship between the presence of a drain after laparoscopic cholecystectomy and the presence of postoperative fluid collection. Thus, in patients without complications, it is not necessary to place a drain to prevent fluid collection.

Prospective Observational Study of Single-Site Multiport Per-umbilical Laparoscopic Endosurgery versus Conventional Multiport Laparoscopic Cholecystectomy: Critical Appraisal of a Unique Umbilical Approach  

PubMed Central

Purpose. This prospective observational study compares an innovative approach of Single-Site Multi-Port Per-umbilical Laparoscopic Endo-surgery (SSMPPLE) cholecystectomy with the gold standard—Conventional Multi-port Laparoscopic Cholecystectomy (CMLC)—to assess the feasibility and efficacy of the former. Methods. In all, 646 patients were studied. SSMPPLE cholecystectomy utilized three ports inserted through three independent mini-incisions at the umbilicus. Only the day-to-day rigid laparoscopic instruments were used in all cases. The SSMPPLE cholecystectomy group had 320 patients and the CMLC group had 326 patients. The outcomes were statistically compared. Results. SSMPPLE cholecystectomy had average operative time of 43.8?min and blood loss of 9.4?mL. Their duration of hospitalization was 1.3 days (range, 1–5). Six patients (1.9%) of this group were converted to CMLC. Eleven patients had controlled gallbladder perforations at dissection. The Visual Analogue Scores for pain on postoperative days 0 and 7, the operative time, and the scar grades were significantly better for SSMPPLE than CMLC. However, umbilical sepsis and seroma outcomes were similar. We had no bile-duct injuries or port-site hernias in this study. Conclusion. SSMPPLE cholecystectomy approach complies with the principles of laparoscopic triangulation; it seems feasible and safe method of minimally invasive cholecystectomy. Overall, it has a potential to emerge as an economically viable alternative to single-port surgery. PMID:24876955

One, two, or three ports in laparoscopic cholecystectomy?  

PubMed

Abstract Single-port laparoscopic cholecystectomy (LC) has been compared with 3- or 4-port LC. To our knowledge, there are no studies comparing the 3-, 2-, and 1-port techniques. Patients were randomized into 3 groups: LC 1-port using SILS, LC 2-port using a laparoscope with a working channel, and LC 3-port using the standard ports. Pain was evaluated at recovery, 4 hours, 24 hours, day 5, and day 8, using an analog visual scale. Homogenous groups in their demographic characteristics; all confirmed gallbladder lithiasis. At recovery, there was less pain in group 1 (P = 0.002); at 4 hours pain was similar in all groups (P = 0.899); at 24 hours there was less pain in groups 2 and 3 (P = 0.031); and at days 5 and 8 there was marginal (P = 0.053) and significant (P = 0.003) relevance. In terms of pain perception, LC performed through 1 port does not offer advantages when compared with 2 or 3 ports. More clinical trials are needed to confirm these data. PMID:25437581

Right liver necrosis: complication of laparoscopic cholecystectomy.  

PubMed

Although bile duct injuries are common among the complications of laparoscopic cholecystectomy, hepatic vascular injuries are not well described. Between January 1990 to December 1999, 83 patients with bile duct injuries have been referred to our clinic. Two of them had liver necrosis due to hepatic arterial occlusion. These two women had laparoscopic cholecystectomy for symptomatic cholelithiasis in district hospitals 4 and 15 days prior to their referral to our clinic. Serum aspartate aminotransferase and alanine aminotransferase levels were found to be 30 to 40-fold higher than normal levels. Ultrasonography, computed tomography and Doppler sonography showed necrosis in the right liver lobe and no flow in the right hepatic artery. Patients were also complicated with liver abscess and biliary peritonitis, respectively. Emergency right hepatectomy was performed in both cases and one of them needed Roux-Y-hepaticojejunostomy (to the left hepatic duct). One patient died of peritonitis in the postoperative period. The other one has no problem in her third postoperative year. The earliest and the simplest method for diagnosis or ruling out hepatic arterial occlusion is detecting the blood biochemistry and Doppler ultrasonography. In some cases emergency hepatectomy can be necessary. Postoperative complications should be expected higher than elective cases. PMID:11813609

A Comparative Study of Single-Port Laparoscopic Surgery Versus Robotic-Assisted Laparoscopic Surgery for Rectal Cancer.  

PubMed

Introduction. Conventional laparoscopic surgery is the treatment of choice for many abdominal procedures. To further reduce surgical trauma, new minimal invasive procedures such as single-port laparoscopic surgery (SPLS) and robotic assisted laparoscopic surgery (RALS) have emerged. The aim of this study was to compare the early results of SPLS versus RALS in the treatment of rectal cancer. Methods. We performed a retrospective analysis of prospectively collected data on patients who had undergone SPLS (n = 36) or RALS (n = 56) in the period between 2010 and 2012. Operative and short-term oncological outcomes were compared. Results. The RALS group had fewer patients with low rectal cancer and more patients with mid-rectal tumors (P = .017) and also a higher rate of intraoperative complications (14.3% vs 0%, P = .021). The rate of postoperative complications did not differ (P = .62). There were no differences in circumferential resection margins, distal resection margins, or completeness of the mesorectal fascia. The RALS group had a larger number of median harvested lymph nodes (27 vs 13, P = .001). The SPLS group had fewer late complications (P = .025). There were no locoregional recurrences in either of the groups. There was no difference in median follow-up time between groups (P = .58). Conclusion. Both SPLS and RALS may have a role in rectal surgery. The short-term oncological outcomes were similar, although RALS harvested more lymph nodes than the SPLS procedure. However, SPLS seems to be safer with regard to intraoperative and late postoperative complications. PMID:25377216

Relevance of day care laparoscopic cholecystectomy in a developing nation.  

PubMed

Feasibility, safety and success of day care laparoscopic cholecystectomy (DCLC) has been well established in advanced countries. The information on (DCLC) is not available from developing nations. All patients of gallstone disease undergoing laparoscopic cholecystectomy under the care of the two participating surgeons at the post graduate Institute of Medical Education & Research were considered for day care laparoscopic cholecystectomy. The selection criteria were: elective cases only, patients less than 70 years, American Society of Anesthesiologists (ASA) grade I and Grade II, living within 20 Kilometers of the hospital, availability of a responsible adult carer at home, access to a telephone and a means of transportation to hospital if needed. Clinical and operative data were recorded prospectively. All patients were discharged 6 to 8 hours after surgery with the advice to contact the surgical team over phone whenever necessary or on the day after discharge. Out of the total 236 laparoscopic cholecystectomy performed over a period of 26 months, 106 patients (44.9%) underwent laparoscopic cholecystectomy as day care procedure. Five patients (4.8%) were admitted after surgery. Four patients were admitted because of conversion and one patient was admitted because of suspected myocardial infarction. Hundred and one patients (95.2%) were discharged on the same day. There was no major morbidity and patient's acceptance was high. Day care laparoscopic cholecystectomy is feasible, safe, and acceptable to patients. PMID:16225056

Sclerosing encapsulating peritonitis: complication of laparoscopic cholecystectomy.  

PubMed

Sclerosing encapsulating peritonitis (SEP) is a rare cause of intestinal obstruction. It is difficult to make a definite preoperative diagnosis, and most cases are diagnosed at the time of laparotomy. It is usually of unknown origin, although, at times, it may be seen secondary to a variety of conditions. Spillage of bile and gallstones at laparoscopic cholecystectomy is an unusual cause of SEP and has not been reported in literature, to date. Contrast-enhanced computed tomography of the abdomen revealed small-bowel loops congregated to the center of the abdomen encased by a soft-tissue density mantle with loculated fluid in the interloop bowel location. Excision of the sac and adhesiolysis was done in our patient for recurrent episodes of intestinal obstruction, who recovered well in the postoperative period. PMID:20374014

Unusual consequences of 'incomplete' laparoscopic cholecystectomy.  

PubMed

In recent years, laparoscopic cholecystectomy (LC) has become the standard surgical practice for the treatment of cholecystolithiasis. As a recognized technical difficulty, it may be associated with the mechanical injury of the gallbladder and/or spilling some of the gallstones into the abdominal cavity. The actual incidence of the latter complication is ~10%. The removal of lost stones from the abdominal cavity is rather elaborate if not infeasible. There is little information about the behaviour of retained gallstones in the free abdominal cavity. Publications report on subsequent intraperitoneal abscesses and fistulas or on the extreme localization of the impacted gallstones. This paper presents two cases with late complications of the abandoned gallstones or gallbladder. Case 1: A 56-year-old female patient underwent an LC 7 years ago. She was recently admitted with a chronic septic condition and suspected autoimmune disease. Preoperative examinations indicated hepatic abscess. Surgery showed gallstones impacted in the gallbladder bed. Case 2: A 59-year-old male patient underwent an LC a year before his admission. His operation was followed by the development of a septic condition and a subphrenic abscess was identified. During his reoperation, a remnant gallbladder containing bile stones was found and removed. Special attention should be paid to careful revision of residual stones during LC. PMID:24129251

A 79-year-old man, with history of recent laparoscopic cholecystectomy, came to our attention for persistent hiccup, dysphonia, and dysphagia. Noninvasive imaging studies showed a nodular lesion in the right hepatic lobe with transdiaphragmatic infiltration and increased tracer uptake on positron emission tomography. Suspecting a malignant lesion and given the difficulty of performing a percutaneous transthoracic biopsy, the patient underwent surgery. Histological analysis of surgical specimen showed biliary gallstones surrounded by exudative inflammation, resulting from gallbladder rupture and gallstones spillage as a complication of the previous surgical intervention. This case highlights the importance of considering such rare complication after laparoscopic cholecystectomy. PMID:23691420

Gastro cutaneous fistula after laparoscopic cholecystectomy: A case report.  

PubMed

A young lady presented with a nonhealing epigastric sinus after 2 years of laparoscopic cholecystectomy performed outside. Upper gastrointestinal (GI) endoscopy and contrast study confirmed its communication with the stomach. At relaparoscopy, the fistula was identified, dissected, and stapled with endo-GIA stapler. Patient made an uneventful postoperative recovery and she is well after 20 months of surgery. It may be concluded that laparoscopic cholecystectomy can lead to the development of gastrocutaneous fistula that can be managed by relaparoscopy and stapling the tract with endo-GIA devices.

A ‘critical view’ on a classical pitfall in laparoscopic cholecystectomy!  

PubMed Central

INTRODUCTION Laparoscopic cholecystectomy is the most common laparoscopic surgery performed by general surgeons. Although being a routine procedure, classical pitfalls shall be regarded, as misperception of intraoperative anatomy is one of the leading causes of bile duct injuries. The “critical view of safety” in laparoscopic cholecystectomy serves the unequivocal identification of the cystic duct before transection. The aim of this manuscript is to discuss classical pitfalls and bile duct injury avoiding strategies in laparoscopic cholecystectomy, by presenting an interesting case report. PRESENTATION OF CASE A 71-year-old patient, who previously suffered from a biliary pancreatitis underwent laparoscopic cholecystectomy after ERCP with stone extraction. The intraoperative situs showed a shrunken gallbladder. After placement of four trocars, the gall bladder was grasped in the usual way at the fundus and pulled in the right upper abdomen. Following the dissection of the triangle of Calot, a “critical view of safety” was established. As dissection continued, it however soon became clear that instead of the cystic duct, the common bile duct had been dissected. In order to create an overview, the gallbladder was thereafter mobilized fundus first and further preparation resumed carefully to expose the cystic duct and the common bile duct. Consecutively the operation could be completed in the usual way. DISCUSSION Despite permanent increase in learning curves and new approaches in laparoscopic techniques, bile duct injuries still remain twice as frequent as in the conventional open approach. In the case presented, transection of the common bile duct was prevented through critical examination of the present anatomy. The “critical view of safety” certainly offers not a full protection to avoid biliary lesions, but may lead to a significant risk minimization when consistently implemented. CONCLUSION A sufficient mobilization of the gallbladder from its bed is essential in performing a critical view in laparoscopic cholecystectomy. PMID:25437680

Critical View of Safety During Laparoscopic Cholecystectomy  

PubMed Central

Background and Objectives: Laparoscopic cholecystectomy has a 0.3% to 0.5% morbidity rate due to major biliary injuries. The majority of surgeons have routinely performed the so-called “infundibular” technique for gallbladder hilar dissection since the introduction of laparoscopy in the early nineties. The “critical view of safety” approach has only been recently discussed in controlled studies. It is characterized by a blunt dissection of the upper part of Calot's space, which does not usually contain arterial or biliary anomalies and is therefore ideal for a safe dissection, even in less experienced hands. Materials and Methods: We applied and compared the critical view of safety triangle approach with the infundibular approach in a retrospective cohort study. We divided 174 patients into 2 groups, with a similar case-mix (cholelithiasis, chronic cholecystitis, and acute cholecystitis). Results of operations performed by a young surgeon using critical view of safety dissection were compared to results of the infundibular approach performed by an experienced surgeon. Outcome values and operative times were examined with univariate analysis (Student t test). Results: No difference occurred in terms of morbidity (even though comparison for biliary injuries is inconclusive because of insufficient power) and outcome; significant differences were found in operative time, favoring the critical view of safety approach in every stage of gallbladder disease, with minor significance for acute cases. Conclusion: We suggest this technique as the gold standard for resident teaching, because it has a similar rate of biliary and hemorrhagic complications but has a shorter operative time, builds self-confidence, and is a simple standardized method both for complicated and uncomplicated gallbladder lithiasis.

Late reoperation for retained gallstone after laparoscopic cholecystectomy.  

PubMed

Complications due to retained gallstones after a laparoscopic cholecystectomy occur in 1.7 per 1000 cases. Significant delay to definitive diagnosis and treatment is common due to late presentation and nonspecific symptoms. Despite the low frequency, complications due to retained gallstones may be serious, including abscess and fistula formation. In the present case, we discuss the removal of abdominal wall and peritoneal stones 8 months after the original laparoscopic cholecystectomy. The case illustrates that complications may arise months to years after the original procedure and requires a high degree of clinical suspicion for expeditious diagnosis. Ultrasound is a sensitive and specific test to identify retained stones. Laparoscopic retrieval is recommended upon identification of intraperitoneal stones within this timeline. PMID:24487171

Factors Influencing the Successful Completion of Laparoscopic Cholecystectomy  

PubMed Central

Objective: To analyze the preoperative factors contributing to the decision to convert laparoscopic to open cholecystectomy. Methods: Retrospective identification of 324 consecutive patients undergoing laparoscopic cholecystectomy, with univariate and multivariate analysis of the following parameters: age, gender, obesity, previous abdominal surgery, presentation with acute cholecystitis, pancreatitis or obstructive jaundice, gallbladder wall thickening, gallbladder or common bile duct stones. Results: Thirty-nine patients (12%) underwent conversion to open cholecystectomy. Patients aged over 65 years were four times more likely to require conversion than patients under 50 years of age. Under 50 years of age, males had equal conversion rates to females, and above this age there was a non-significant increased conversion rate in males. Obese patients had higher conversion rates than non-obese patients (23% versus 9%, P < 0.003). Thirty-eight percent of patients with choledocholithiasis required conversion. Age, acute cholecystitis and choledocholithiasis independently predicted conversion. A patient aged less than fifty years with neither acute cholecystitis nor choledocholithiasis had a conversion rate of just 2%, while almost 60% of those over 65 years of age with acute cholecystitis or choledocholithiasis required conversion. Conclusion: The parameters of age, acute cholecystitis and choledocholithiasis must be considered in the clinical decision making process when planning laparoscopic cholecystectomy. PMID:20202401

Endoscopic management of biliary leaks after laparoscopic cholecystectomy.

Laparoscopic cholecystectomy has become the procedure of choice for management of symptomatic cholelithiasis. Although it has distinct advantages over open cholecystectomy, bile leak is more common. Endoscopic retrograde cholangiopancreatography is the diagnostic and therapeutic modality of choice for management of postcholecystectomy bile leaks and has a high success rate with the placement of plastic biliary stents. Repeat endoscopic retrograde cholangiopancreatography with placement of multiple plastic stents, a covered metal stent, or possibly cyanoacrylate therapy may be effective in refractory cases. This review will discuss the indications, efficacy, and complications of endoscopic therapy. PMID:24296422

Use of CO2 laser flexible waveguides during laparoscopic cholecystectomy  

NASA Astrophysics Data System (ADS)

Laparoscopic cholecystectomy has revolutionized the management of symptomatic cholelithiasis and cholecystitis. Although electrosurgery devices are used by a majority of surgeons, laser technology is a valued addition to the armamentarium of the skilled laser laparoscopist. A variety of fiberoptic capable wavelengths have been applied successfully during this procedure. Use of the CO2 laser for this purpose has lagged due to difficulties encountered with free-beam and rigid waveguide dissections via the laparoscope. Recent developments in flexible waveguide technology have the potential to expand the role of the CO2 laser for laparoscopic cholecystectomy and other procedures. Twelve laparoscopic cholecystectomies were performed using Luxar (Bothell, WA) flexible microwaveguides of various configurations. In each case, dissection of the gallbladder from the gallbladder bed was accomplished with acceptable speed and hemostasis. There were no complications. Shortcomings include coupling and positioning with an articulated arm and occasional clogging of some waveguide tips with debris. Modifications of this technology are suggested. Flexible waveguides make the CO2 laser a practical alternative for surgical laparoscopy.

Band ligation of the perforated gall bladder during laparoscopic cholecystectomy.  

PubMed

Perforation of the gall bladder is a frequent complication during laparoscopic cholecystectomy. Grasping the perforated part of the gall bladder, clip application, or endoscopic loop application are possible solutions to prevent spillage. We propose laparoscopic rubber band application to close the perforated part of the gall bladder as an easy and safe method. We performed rubber band application after iatrogenic perforation of the gall bladder during laparoscopic cholecystectomy in 5 patients. Two-millimeter-wide multiple rubber rings, cut from a 14-Fr Foley catheter, are loaded on a grasper. When a perforation occurred during the dissection of the gall bladder, the hole is grasped with this instrument and 1 of the rings is placed on the gall bladder by the aid of a dissector. Thus, the grasper remained available for traction of the Hartmann's pouch during further dissection of the gall bladder. The rubber bands were placed successfully in all cases. Two perforations occurred in 1 case, and 2 bands were placed with ease. Bile leakage or gall stone spillage did not occur. Operation time was not prolonged. Rubber band ligation of perforation of the gall bladder is a simple, safe, inexpensive, and effective method to prevent spillage of the bile or gallstones in laparoscopic surgery. PMID:18097314

Laparoscopic Cholecystectomy in a Patient with Previous Pneumonectomy: A Case Report and Discussion of Anaesthetic Considerations  

PubMed Central

Increasing numbers of patients require cholecystectomy after previous pneumonectomy, but there are little data to guide anaesthetic management. A laparoscopic approach is associated with less postoperative respiratory compromise than open cholecystectomy but may be relatively contraindicated due to the undesirable effects of pneumoperitoneum on respiratory function. We describe the case of a 72-year-old patient who successfully underwent elective laparoscopic cholecystectomy 23 years after left pneumonectomy. An understanding of the combined physiological consequences of pneumonectomy and pneumoperitoneum facilitated the provision of safe and uneventful anaesthesia. We propose that laparoscopic cholecystectomy is feasible and safe to perform in patients with a single lung. PMID:25431680

Laparoscopic cholecystectomy in a patient with erythropoietic protoporphyria.  

PubMed

Erythropoietic protoporphyria (EPP) is an inherited defect in haem synthesis causing dangerous phototoxic reactions following exposure to wavelengths of light around 400nm. It can cause catastrophic post-operative complications following open surgery, in which environment various safety measures are now routinely employed. The dangers at laparoscopy have never been discussed in the literature, and nor have any specific precautions been recommended. We describe a 35 year old woman with gallstones undergoing prophylactic laparoscopic cholecystectomy to prevent future cholestasis precipitating porphyric liver failure. A pre-operative trial of the cutaneous effects of the laparoscopic light source was performed to assess the potential risk of use within the peritoneal cavity. The procedure was uneventful and the patient suffered no adverse reaction. We suggest that a trial of the effects of the laparoscopic light source on the skin of EPP patients provides valid reassurance regarding the safety of the laparoscopy for short surgical procedures.

Recurrent Asystolic Cardiac Arrest and Laparoscopic Cholecystectomy: A Case Report and Review of the Literature  

PubMed Central

Laparoscopic surgery has become a durable alternative for both gynecologic and general surgical procedures, but reported complications are increasing. We describe the case of a 70-year-old male undergoing routine laparoscopic cholecystectomy for gallstone pancreatitis who developed asystolic cardiac arrest intraoperatively. A review of the literature revealed 2 cases of asystolic cardiac arrest during laparoscopy: one was during laparoscopic cholecystectomy and one was during diagnostic laparoscopy for gynecologic evaluation.

Antibiotic Prophylaxis in Laparoscopic Cholecystectomy: A Randomized Controlled Trial  

PubMed Central

Background Recent meta-analyses concluded that antibiotic prophylaxis is not warranted in low-risk laparoscopic cholecystectomy. However, most trials in the meta-analyses had a relatively small sample size and were statistically underpowered. In addition, many of the trials mentioned potential cost savings owing to the elimination of prophylactic antibiotics. However, no trial has statistically estimated the cost effectiveness. To evaluate the results of meta-analyses, we conducted a randomized controlled trial on the role of prophylactic antibiotics in low-risk laparoscopic cholecystectomy with an adequate sample size. Methods From March 2007 to May 2013, at the Department of Surgery, Kansai Medical University, patients who were scheduled for elective laparoscopic cholecystectomy were randomly assigned to one of two arms: those who were and were not administered prophylactic antibiotics. The primary endpoint was the occurrence of postoperative infections and secondary endpoints were postoperative hospital stay and medical costs. Findings During the study period, 518 patients were assigned to the Antibiotics group and 519 to the No antibiotics group. Occurrences of surgical site infections, distant infections and overall infections were significantly lower in the Antibiotics group than in the No antibiotics group (0.8 vs. 3.7%, p?=?0.001, OR: 0.205 (95%CI: 0.069 to 0.606); 0.4 vs. 3.1%, p?=?0.0004, OR: 0.122 (95%CI: 0.028 to 0.533); 1.2 vs. 6.7%; p<0.0001, OR: 0.162 (95%CI: 0.068 to 0.389), respectively). The postoperative hospital stay was significantly shorter in the Antibiotics group (mean, SD: 3.69±1.56 vs. 4.07±3.00; p?=?0.01) and the postoperative medical costs were significantly lower in the Antibiotics group (mean, SD: $766±341 vs. 832±670; p?=?0.047). Multivariable analysis showed that independent risk factors for postoperative infectious complications were no prophylactic antibiotics (p<0.0001) and age 65 or older (p?=?0.006). Conclusions Perioperative administration of prophylactic antibiotics should be recommended in laparoscopic cholecystectomy to prevent postoperative infectious complications and to reduce medical costs.

Diagnosis of incidental gallbladder cancer after laparoscopic cholecystectomy: our experience  

PubMed Central

Background Gallbladder carcinoma is a rare high malignancy neoplasm. The incidence of intra or post-operative incidental gallbladder carcinoma diagnosis is estimated between 0,2 and 2,8%. Primary aim of our study is to evaluate incidental gallbladder carcinoma's incidence in our experience. Methods We retrospectively reviewed our Surgery Division's experience about the totality of laparoscopic cholecystectomies with post-operative histological evidence of incidental gallbladder cancer. We evaluated patients' characteristics, surgical related variables, histological response, surgivcal radicalization characteristics and surgical outcome. Results In the considered sample we observed 7 accidental gallbladder adenocarcinomas in post-operative histological examination. Pathological results were:1 pT1b N0 (G1), 2 pT2 N0 (G2), 2 pT2 N1 (G3b), 2 pT3 N1 (G3b) (Table 1). In 5 cases we performed neoplasm radicalization surgery with standard procedure revision. Two patients died before radicalization. Median global survival was 34 months. Conclusion With the increase of laparoscopic cholecystectomies both elective and urgent performed in our centre we observed also an increase of incidentally diagnosed gallbladder neoplasms. Early diagnosis, meticulous peri-operative study and accurate surgical strategy are essential factors to obtain good results in incidental gallbladder cancer. PMID:24268097

Early visceral pain predicts chronic pain after laparoscopic cholecystectomy.  

PubMed

Chronic pain after laparoscopic cholecystectomy is related to postoperative pain during the first postoperative week, but it is unknown which components of the early pain response is important. In this prospective study, 100 consecutive patients were examined preoperatively, 1week postoperatively, and 3, 6, and 12months postoperatively for pain, psychological factors, and signs of hypersensitivity. Overall pain, incisional pain (somatic pain component), deep abdominal pain (visceral pain component), and shoulder pain (referred pain component) were registered on a 100-mm visual analogue scale during the first postoperative week. Nine patients developed chronic unexplained pain 12months postoperatively. In a multivariate analysis model, cumulated visceral pain during the first week and number of preoperative biliary pain attacks were identified as independent risk factors for unexplained chronic pain 12months postoperatively. There were no consistent signs of hypersensitivity in the referred pain area either pre- or postoperatively. There were no significant associations to any other variables examined. The risk of chronic pain after laparoscopic cholecystectomy is relatively low, but significantly related to the visceral pain response during the first postoperative week. PMID:25250720

Preoperative administration of intramuscular dezocine reduces postoperative pain for laparoscopic cholecystectomy  

PubMed Central

Postoperative pain is the most common complaint after laparoscopic cholecystectomy. This study was carried out to evaluate whether preoperative administration of intramuscular dezocine can provide postoperative analgesia and reduce postoperative opioid consumption in patients undergoing laparoscopic cholecystectomy. Patients (ASA I or II) scheduled for laparoscopic cholecystectomy were randomly assigned into intramuscular dezocine group (group 1) or intramuscular normal saline group (group 2). Dezocine and equal volume normal saline were administered intramuscularly 10 min before the induction of anesthesia. After operation, the severity of postoperative pain, postoperative fentanyl requirement, incidence and severity of side-effects were assessed. Postoperative pain and postoperative patient-controlled fentanyl consumption were reduced significantly in group 1 compared with group 2. The incidence and severity of side effects were similar between the two groups. Preoperative single-dose administration of intramuscular dezocine 0.1 mg/kg was effective in reducing postoperative pain and postoperative patient-controlled fentanyl requirement in patients undergoing laparoscopic cholecystectomy.

Intraoperative cholangiography during laparoscopic cholecystectomy. Routine vs selective policy.  

PubMed

An audit of routine intraoperative cholangiography in a consecutive series of 496 patients undergoing laparoscopic cholecystectomy has been performed. Cannulation of the cystic duct was possible in 483 patients (97%). The use of portable, digitized C-arm fluorocholangiography was vastly superior to the employment of a mobile x-ray machine and static films in terms of reduced time to carry out the procedure and total abolition of unsatisfactory radiological exposure of the biliary tract. Repeat of the procedure was necessary in 22% of cases when the mobile x-ray equipment was used. Aside from the detection of unsuspected stones in 18 patients (3.9%), routine intraoperative cholangiography identified four patients (0.8%) whose management would undoubtedly have been disadvantaged if intraoperative cholangiography had not been performed.

An "all 5-mm ports" selective approach to laparoscopic cholecystectomy, appendectomy, and anti-reflux surgery.  

PubMed

Laparoscopic appendectomy, cholecystectomy, or anti-reflux procedures are conventionally performed with the use of one and often two 10/12-mm ports. While needlescopic or micropuncture laparoscopic procedures reduce postoperative pain, they invariably involve the use of one 10/12-mm port and the instruments applied have their ergo-dynamic shortcomings. Between September 2002 and March 2003, we have attempted an "all 5-mm ports" approach in 49 laparoscopic procedures, which included 18 of 59 laparoscopic cholecystectomies (31%), 26 diagnostic laparoscopies for suspected appendicitis (of which we proceeded to a laparoscopic appendectomy in 17 patients), and in the last 5 of 9 laparoscopic Nissen fundoplications. Conversion of one of the 5-mm ports to a 10-mm port was required in 5 of the 18 (28%) laparoscopic cholecystectomies and in 6 of the 17 (35%) laparoscopic appendectomies to facilitate organ retrieval in patients with large gallstones (>5 mm in diameter) and in obese patients with fatty mesoappendix. There were no conversions to open surgery. No significant differences in the operating time between the laparoscopic procedures performed by the all 5-mm ports approach or the conventional approach were observed. No intraoperative or postoperative complications occurred in this series. The "all 5-mm ports" approach to laparoscopic cholecystectomy and appendectomy in selected patients and to laparoscopic fundoplication appears feasible and safe. A randomised comparison between this approach and the conventional laparoscopic approach to elective cholecystectomy and fundoplication in which two of the ports employed are of the 10-mm diameter is warranted.

Growing use of laparoscopic cholecystectomy in the national Veterans Affairs Surgical Risk Study: effects on volume, patient selection, and selected outcomes.  

PubMed Central

OBJECTIVE: To study the introduction of laparoscopic cholecystectomy to the 43 tertiary-care university-affiliated Veterans Administration medical centers (VAMCs) participating in the National Veterans Affairs Surgical Risk Study from October 1991 through December 1993. SUMMARY BACKGROUND DATA: Previous studies in the private sector have documented growth in the number of cholecystectomies and falling clinical thresholds for cholecystectomy with the introduction of laparoscopic cholecystectomy. METHODS: The following were analyzed for changes over time: measures of patient preoperative risk, complexity of surgery, severity of biliary disease, numbers of procedures, postoperative length of stay, and 30-day postoperative mortality and general complication rates. RESULTS: The number of cholecystectomies performed laparoscopically increased, but the total number of cholecystectomies performed remained stable over time. The proportion of patients with acute cholecystitis, emergent cholecystectomies, and technically complex cholecystectomies did not change or increased slightly over time. Adjusted odds for postoperative general complications were lower for laparoscopic than for open cholecystectomy, but 30-day postoperative mortality and general complication rates for all cholecystectomies remained constant over time. Postoperative length of stay for all cholecystectomies fell significantly. Implementation rates of laparoscopic cholecystectomy varied widely between hospitals. Laparoscopic cholecystectomy was adopted more slowly and used in a lower percentage of cholecystectomies than in non-VA settings. CONCLUSIONS: In contrast to non-VA studies showing increases in overall cholecystectomy volume since the introduction of laparoscopic cholecystectomy, these VAMCs implemented laparoscopic cholecystectomy without growth in cholecystectomies or a change in the clinical threshold for cholecystectomy. Laparoscopic cholecystectomy was associated with better outcomes, but its introduction in the setting of stable cholecystectomy volume and biliary disease case mix did not change postoperative mortality and complication rates. The stable cholecystectomy volume and biliary disease case mix, slower adoption, and lower use of laparoscopic cholecystectomy contrast with previous reports and may result from differences in patients and organization and financing of VA versus non-VA settings.

Effects of laparoscopic cholecystectomy on lung function: A systematic review  

PubMed Central

AIM: To present and integrate findings of studies investigating the effects of laparoscopic cholecystectomy on various aspects of lung function. METHODS: We extensively reviewed literature of the past 24 years concerning the effects of laparoscopic cholecystectomy in comparison to the open procedure on many aspects of lung function including spirometric values, arterial blood gases, respiratory muscle performance and aspects of breathing control, by critically analyzing physiopathologic interpretations and clinically important conclusions. A total of thirty-four articles were used to extract information for the meta-analysis concerning the impact of the laparoscopic procedure on lung function and respiratory physiopathology. The quality of the literature reviewed was evaluated by the number of their citations and the total impact factor of the corresponding journals. A fixed and random effect meta-analysis was used to estimate the pooled standardized mean difference of studied parameters for laparoscopic (LC) and open (OC) procedures. A crude comparison of the two methods using all available information was performed testing the postoperative values expressed as percentages of the preoperative ones using the Mann-Whitney two-sample test. RESULTS: Most of the relevant studies have investigated and compared changes in spirometric parameters.The median percentage and interquartile range (IQR) of preoperative values in forced vital capacity (FVC), forced expiratory volume in 1 s and forced expiratory flow (FEF) at 25%-75% of FVC (FEF25%-75%) expressed as percentage of their preoperative values 24 h after LC and OC were respectively as follows: [77.6 (73.0, 80.0) L vs 55.4 (50.0, 64.0) L, P < 0.001; 76.0 (72.3, 81.0) L vs 52.5 (50.0, 56.7) L, P < 0.001; and 78.8 (68.8, 80.9) L/s vs 60.0 (36.1, 66.1) L/s, P = 0.005]. Concerning arterial blood gases, partial pressure of oxygen [PaO2 (kPa)] at 24 or 48 h after surgical treatment showed reductions that were significantly greater in OC compared with LC [LC median 1.0, IQR (0.6, 1.3); OC median 2.4, IQR (1.2, 2.6), P = 0.019]. Fewer studies have investigated the effect of LC on respiratory muscle performance showing less impact of this surgical method on maximal respiratory pressures (P < 0.01); and changes in the control of breathing after LC evidenced by increase in mean inspiratory impedance (P < 0.001) and minimal reduction of duty cycle (P = 0.01) compared with preoperative data. CONCLUSION: Laparoscopic cholecystectomy seems to be associated with less postoperative derangement of lung function compared to the open procedure. PMID:25516676

Contemporary experience with cholecystectomy: establishing 'benchmarks' two decades after the introduction of laparoscopic cholecystectomy.  

PubMed

With quality and public reporting of increasing importance, benchmarks are anticipated to grow in relevance. We studied cholecystectomy in a practice in an urban tertiary care hospital. A total of 1083 cholecystectomies were performed in 2008 and 2009. Laparoscopic cholecystectomy was performed in 97.8 per cent of patients with a 2.2 per cent conversion rate. A planned open procedure was performed in only 2.2 per cent of patients. Approximately half of procedures were urgent and performed during an acute hospitalization. Most patients (74%) were female and most patients were overweight or obese (64.8%). Ages into the tenth decade of life were represented. Comorbidities included hypertension, 28.7 per cent; coronary disease, 15.6 per cent; diabetes mellitus, 13.4 per cent; gastroesophageal reflux disease, 10.7 per cent; and asthma, 5.5 per cent. Of female patients, 98 (12.2%) were postpartum and five (0.6%) were pregnant. Of 137 patients without gallstones, 59.1 per cent had biliary dyskinesia and 27 per cent had acalculous cholecystitis. Preoperative magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP) were performed in most patients with suspected choledocholithiasis. Intraoperative cholangiograms were performed in 6.9 per cent of patients, 3.3 per cent for abnormal liver function studies. Postoperative ERCP was used in most patients with positive intraoperative cholangiograms. All-cause mortality was 0.8 per cent and attributable mortality was 0.2 per cent. Complications occurred in 7.5 per cent of patients, including retained common bile duct stones in 1.1 per cent, bile duct leak in 0.3 per cent, and common bile duct injury in 0.1 per cent.

Comparative Changes in Tissue Oxygenation Between Laparoscopic and Open Cholecystectomy  

PubMed Central

Background Previous studies examined the effect of laparoscopic cholecystectomy (LC) versus open cholecystectomy (OC) on physiological variables of the respiratory system. In this study we compared changes in arterial blood gases-related parameters between LC and OC to assess their comparative influence on gas exchange. Methods We studied 28 patients, operated under identical anesthetic protocol (LC: 18 patients, OC: 10 patients). Measurements were made on the morning before surgery (BS), the second (AS2) and the eighth (AS8) postoperative day. Studied parameters, including alveolar-arterial difference in PO2 ((A-a)DO2) and oxygen content (Oct in vol%), were statistically compared. Results On AS2 a greater increase was found in ((A-a)DO2) for the OC compared to LC (4.673 ± 0.966 kPa versus 3.773 ± 1.357 kPa, respectively). Between BS and AS2, Oct in vol% decreased from 17.55 ± 1.90 to 15.69 ± 1.88 in the LC and from 16.99 ± 2.37 to 14.62 ± 2.23 in the OC, whilst a reduction (P = 0.093) between AS2 and AS8 was also found for the open method. Besides, on AS2, SaO2% decrease was greater in OC compared to LC (P = 0.096). Conclusions On AS2, the greater increase in OC-((A-a)DO2) associated with Oct in vol% and SaO2% findings also in OC group suggest that LC might be associated with lower risk for impaired tissue oxygenation.

Single incision laparoscopic cholecystectomy (SILS) for a patient with situs inversus totalis.  

PubMed

Laparoscopic surgery has become the gold standard for the surgical treatment of benign disorders of bile ducts, for example, symptomatic cholelithiasis. Nowadays, laparoscopic surgery is becoming less invasive by means of the advanced technologic capabilities. In this article, the authors present a 65-year-old patient with situs inversus totalis who was examined because of abdominal pain and dyspeptic symptoms. Ultrasonography and tomography revealed cholecystitis with gallstones (calculous cholecystitis), besides, it was observed that the liver and the gall bladder were on the left side and the heart, the stomach and the spleen were located on the right side of the patient. The patient was performed single incision laparoscopic cholecystectomy. The patient was discharged on the postoperative day 1. In the present article, the authors described how easily the single incision laparoscopic cholecystectomy could resolve the technical difficulties encountered in the patients with situs inversus totalis during the conventional laparoscopic surgery.

Laparoscopic Cholecystectomy Under Epidural Anesthesia: A Feasibility Study  

PubMed Central

Background: Laparoscopic cholecystectomy (LC) is normally performed under general anesthesia. But of late this operation has been tried under regional anesthesia successfully without any added complications like epidural anesthesia. Aims: The aim of the study was to study the feasibility of performing LC under epidural anesthesia in normal patients so that the benefits could be extended to those high-risk patients having symptomatic gallstone disease and compromised cardio-pulmonary status where general anesthesia is contraindicated. Materials and Methods: In all, 20 patients with the American Society of Anesthesiologist's class I or II were enrolled in the study. The level of epidural block and satisfaction score, both for the patient and the surgeon, were noted in the study. Results: The LC was performed successfully under epidural anesthesia in all but two patients who had severe shoulder pain in spite of giving adequate analgesia and were converted to general anesthesia. Conclusions: The LC can be performed safely under epidural anesthesia with understanding between patient and surgeon. However, careful assessment of complications in the patients should be done to make the procedure safer. PMID:25535604

Early endoscopic retrograde cholangiopancreatography after laparoscopic cholecystectomy can strain the occurrence of trocar site hernia  

PubMed Central

This study reports a 69-year-old, obese, female patient presenting with a biliary leakage after laparoscopic cholecystectomy for cholelithiasis. Closure of the umbilical trocar site had been neglected during the laparoscopic cholecystectomy. Early, on postoperative day five, endoscopic retrograde cholangiopancreatography (ERCP) requirement after laparoscopic cholecystectomy resolved the biliary leakage problem but resulted with a more complicated clinical picture with an intestinal obstruction and severe abdominal pain. Computed tomography revealed a strangulated hernia from the umbilical trocar site. Increased abdominal pressure during ERCP had strained the weak umbilical trocar site. Emergency surgical intervention through the umbilicus revealed an ischemic small bowel segment which was treated with resection and anastomosis. This report demonstrates that negligence of trocar site closure can result in very early herniation, particularly if an endoscopic intervention is required in the early postoperative period.

Triple, double- and single-incision laparoscopic cholecystectomy: a prospective study  

PubMed Central

Purpose: Advances in laparoscopic techniques have enabled complicated intra-abdominal surgical procedures to be made with less trauma and a better cosmetic appearance. The techniques have been developed by decreasing the number of incisions in conventional laparoscopic procedures in order to increase patient satisfaction. The aim of this study was to compare the results of cholecystectomies made with 3, 2 or a single incision. Method: A total of 95 cholecystectomy patients from Elbistan State Hospital and Suleyman Demirel University Hospital between 2011 and 2013 were prospectively evaluated. The patients were separated into 3 groups as triple incision laparoscopic cholecystectomy (TILC), double incision laparoscopic cholecystectomy (DILC) and single incision laparoscopic cholecystectomy (SILC). Patients were evaluated in respect of demographic characteristics, operation time, success rate, analgesia requirement, length of hospital stay and patient satisfaction. Results: Successful procedures were completed in 40 TILC, 40 DILC and 15 SILC cases. Transfer to open cholecystectomy was not required in any case. The mean duration of operation was 71 mins (range, 55-120 mins) for SILC cases, 45 mins (range, 32-125 mins) for DILC cases and 42 mins (range, 29-96 mins) for TILC cases. The mean time for the SILC cases was statistically significantly longer than the other two groups (p < 0.000). Conclusions: At a comparable level with DILC and TILC, single incision laparosccopic cholecystectomy is a method which can be used without incurring any extra costs or requiring additional instrumentation or training and which has good cosmetic results and a low requirement for analgesia.

Immediate Postoperative Pain: An Atypical Presentation of Dropped Gallstones after Laparoscopic Cholecystectomy  

PubMed Central

Cholecystectomy is one of the most commonly performed surgical procedures in the United States. A common complication is dropped gallstones, and the diversity of their presentation poses a substantial diagnostic challenge. We report the case of a 58-year-old man presenting with chronic right upper quadrant hours status post cholecystectomy. Imaging demonstrated retained gallstones in the perihepatic space and symptoms remitted following their removal via laparoscopic operation. Gallstones are lost in roughly 1 in 40 cholecystectomies and are usually asymptomatic. The most common presentations are months or years status post cholecystectomy due to fistula, abscess, or sinus tract formation. We report this case hoping to bring light to a rare presentation for dropped gallstones and provide advice on the management of this common complication of cholecystectomy. PMID:25649178

Three-port laparoscopic cholecystectomy in a brazilian Amazon woman with situs inversus totalis: surgical approach.  

PubMed

Situs inversus totalis (SIT) is an uncommon anomaly characterized by transposition of organs to the opposite side of the body in a mirror image of normal. We report on an adult woman, born and resident in Brazilian Amazonia, presenting acute pain located at the left hypochondrium and epigastrium. During clinical and radiological evaluation, the patient was found to have SIT and multiple stones cholelithiasis. Laparoscopic cholecystectomy was safely performed with the three-port technique in a reverse fashion. In conclusion, this case confirms that three-port laparoscopic cholecystectomy is a safe and feasible surgical approach to treat cholelithiasis even in rare and challenging conditions like SIT.

[Intraoperative ERCP for therapy of common bile duct stones during laparoscopic cholecystectomy].  

PubMed

The data of 166 patients that underwent laparoscopic cholecystectomy between November 1989 and December 1997 are given. In all cases intraoperative ERC and extraction of bile duct stones within the laparoscopic surgery were performed. The results show that by intraoperative simultaneous ERC bile duct stones can be removed with a success rate of 98.8% and a mortality rate of 0%. Intraoperative ERC is a secure and economic kind of treatment, especially the patient profits from this minimal invasive procedure. PMID:10327582

Meta-Analysis of Drainage Versus No Drainage After Laparoscopic Cholecystectomy  

PubMed Central

Background and Objectives: Routine drainage after laparoscopic cholecystectomy is still controversial. This meta-analysis was performed to assess the role of drains in reducing complications in laparoscopic cholecystectomy. Methods: An electronic search of Medline, Science Citation Index Expanded, Scopus, and the Cochrane Library database from January 1990 to June 2013 was performed to identify randomized clinical trials that compare prophylactic drainage with no drainage in laparoscopic cholecystectomy. The odds ratio for qualitative variables and standardized mean difference for continuous variables were calculated. Results: Twelve randomized controlled trials were included in the meta-analysis, involving 1939 patients randomized to a drain (960) versus no drain (979). The morbidity rate was lower in the no drain group (odds ratio, 1.97; 95% confidence interval, 1.26 to 3.10; P = .003). The wound infection rate was lower in the no drain group (odds ratio, 2.35; 95% confidence interval, 1.22 to 4.51; P = .01). Abdominal pain 24 hours after surgery was less severe in the no drain group (standardized mean difference, 2.30; 95% confidence interval, 1.27 to 3.34; P < .0001). No significant difference was present with respect to the presence and quantity of subhepatic fluid collection, shoulder tip pain, parenteral ketorolac consumption, nausea, vomiting, and hospital stay. Conclusion: This study was unable to prove that drains were useful in reducing complications in laparoscopic cholecystectomy. PMID:25516708

Imaging in laparoscopic cholecystectomy--what a radiologist needs to know.  

PubMed

Laparoscopic cholecystectomy is the gold standard treatment option for cholelithiasis. In order to properly assess for the complications related to the procedure, an understanding of the normal biliary anatomy, its variants and the normal postoperative imaging is essential. Radiologist must be aware of benefits and limitations of multiple imaging modalities in characterizing the complications of this procedure as each of these modalities have a critical role in evaluating a symptomatic post-cholecystectomy patient. The purpose of this article is describe the multi-modality imaging of normal biliary anatomy and its variants, as well as to illustrate the imaging features of biliary, vascular, cystic duct, infectious as well as miscellaneous complications of laparoscopic cholecystectomy. We focus on the information that the radiologist needs to know about the radiographic manifestations of potential complications of this procedure. PMID:24657107

Management of bile duct stones in the era of laparoscopic cholecystectomy.  

PubMed

The development of laparoscopic cholecystectomy has transformed many aspects of gallstone disease management, particularly the care of patients with known or suspected bile duct stones. New obstacles to operative access to the bile duct have stressed the importance of accurate clinical prediction and detection of bile duct stones and led to increased reliance on nonsurgical approaches, especially pre- or postoperative endoscopic retrograde cholangiopancreatography and sphincterotomy, as well as spurring the development of new techniques such as laparoscopic common bile duct exploration. This work reviews the key features and rational usage of the endoscopic, laparoscopic and open surgical procedures, as well as other adjunct techniques, employed in the treatment of bile duct stones, emphasizing current options in the approach to this problem in the perilaparoscopic cholecystectomy setting. Management of bile duct stones in other special clinical circumstances and the potential future role of emerging technologies are also discussed. PMID:9571375

Major Bile Duct Injuries Associated With Laparoscopic Cholecystectomy  

PubMed Central

Objective To assess the quality of life (QOL) of patients after surgical reconstruction of a major bile duct injury from laparoscopic cholecystectomy (LC). Summary Background Data The incidence of bile duct injuries has increased dramatically since the introduction and widespread use of LC. Previous reports show that at long-term follow-up, most patients surgically repaired will have a successful outcome as measured by standard clinical parameters. However, there is a general impression that these patients have an impaired QOL. Data addressing QOL of these patients are limited. Methods A standard QOL questionnaire was sent to 89 patients after successful surgical repair of a major bile duct injury from a LC treated at the Johns Hopkins Hospital between 1990 and 2000. The instrument consisted of 30 items on a visual analog scale categorized into physical (15 items), psychological (10 items), and social (5 items) domains. The same questionnaire was sent to age- and sex-matched healthy controls (n = 100) and to patients who underwent uncomplicated LC (n = 100). An additional portion of the questionnaire inquired about outcome measures and legal action undertaken by patients. Results Overall QOL scores for bile duct injury patients in the three domains (physical, psychological, and social) were 76%, 77%, and 75%, respectively. QOL scores were comparable to those of patients undergoing uncomplicated LC and healthy controls in the physical and social domains but were significantly different in the psychological domain. Presenting symptoms, prior repair, level of injury, number of stents, length of postoperative stenting, and length of follow-up did not influence QOL scores. Repaired patients reported similar rates of abdominal pain, change in bowel habits, use of pain medications, and recent symptoms of fever or chills as LC controls. Thirty-one percent of responding bile duct injury patients reported having sought legal recourse for their injury. All QOL domain scores were significantly lower in the patients who pursued a lawsuit versus those who did not. Conclusions This study provides formal data evaluating QOL after surgical repair of major bile duct injuries from LC. Although there was a significant difference in the QOL as evaluated from a psychological dimension, bile duct injury patients reported QOL scores in the physical and social domains comparable to those of control patients. The decreased QOL assessment in the psychological dimension may be attributable to the prolonged, complicated, and unexpected nature of these injuries. The presence of a lawsuit appears to be associated with a poorer QOL assessment. PMID:12035047

Operative Outcome and Patient Satisfaction in Early and Delayed Laparoscopic Cholecystectomy for Acute Cholecystitis  

PubMed Central

Introduction. Early laparoscopic cholecystectomy is usually associated with reduced hospital stay, sick leave, and health care expenditures. Early diagnosis and treatment of acute cholecystitis reduce both mortality and morbidity and the accurate diagnosis requires specific diagnostic criteria of clinical data and imaging studies. Objectives. To compare early versus delayed laparoscopic cholecystectomy regarding the operative outcome and patient satisfaction. Patients and Methods. Patients with acute cholecystitis were divided into two groups, early (A) and delayed (B) cholecystectomy. Diagnosis of acute cholecystitis was confirmed by clinical examination, laboratory data, and ultrasound study. The primary end point was operative and postoperative outcome and the secondary was patient's satisfaction. Results. The number of readmissions in delayed treatment group B was three times in 10% of patients, twice in 23.3%, and once in 66.7% while the number of readmissions was once only in patients in group A and the mean total hospital stays were higher in group B than in group A. The overall patient's satisfaction was 92.66 ± 6.8 in group A compared with 75.34 ± 12.85 in group B. Conclusion. Early laparoscopic cholecystectomy resulted in significant reduction in length of hospital stay and accepted rate of operative complications and conversion rates when compared with delayed techniques.

Retroperitoneal Abscess Formation as a Result of Spilled Gallstones during Laparoscopic Cholecystectomy: An Unusual Case Report  

PubMed Central

One of the complications of laparoscopic cholecystectomy for gallstone disease that seems to exceed that of the traditional open method is the gallbladder perforation and gallstone spillage. Its incidence can occur in up to 40% of patients, and in most cases its course is uneventful. However in few cases an abdominal abscess can develop, which may lead to significant morbidity. Rarely an abscess formation due to spilled and lost gallstones may occur in the retroperitoneal space. We herein report the case of a female patient who presented with clinical symptoms of sepsis six months following laparoscopic cholecystectomy. Imaging investigations revealed the presence of a retroperitoneal abscess due to retained gallstones. Due to patient's decision to refuse abscess's surgical drainage, she underwent CT-guided drainage. The 24-month followup of the patient has been uneventful, and the patient remains in good general condition. PMID:23227410

Evaluation of the role of prophylactic antibiotics in elective laparoscopic cholecystectomy: a prospective randomized trial.  

PubMed

At present the use of prophylactic antibiotics in elective laparoscopic cholecystectomy is controversial. This prospective study was carried out to define the role of prophylactic antibiotics in elective laparoscopic cholecystectomy to prevent postoperative infection. Ninety three patients were randomly placed in two groups. Group A comprised of 40 while group B consisted of 53 patients. Patients in Group A received 1.5 grams of second generation cephalosporin (cefuroxime sodium) diluted in 100ml of normal saline, at the time of induction of anesthesia. Group B patients received an equal volume of normal saline only. A sample of gall bladder bile was collected by direct gall bladder puncture intra-operatively for aerobic and anaerobic culture. Age, sex, weight of the patient, American Society of Anesthesiologists classification grade, presence of diabetes mellitus, episodes of colic 30 days preceding surgery, intra-operative gall bladder rupture, stone and / or bile spillage, results of bile culture, gall bladder histology, length of hospital stay, and number of septic complications were recorded and analyzed. In group A, one patient (2.5%) had post operative wound infection and in group B, two patients (3.8%) had post operative infection which was statistically similar (p>0.1). There was no difference between the two groups in terms of demographic, intra operative and post operative denominators. Therefore the study concluded that prophylactic antibiotics did not have a significant role to play in prevention of postoperative wound infection in elective laparoscopic cholecystectomy.

Robotic Single-Port Hernia Surgery  

PubMed Central

Background and Objectives: Since the introduction of single-incision laparoscopic surgery in 2009, an increasing number of surgical procedures including hernia repair are being performed using this technique. However, its large-scale adoption awaits results of prospective randomized controlled studies confirming its potential benefits. Parallel with single-port surgery development, the issue of the chronic lack of good camera assistants is being addressed by the robotic Freehand® camera controller, which has the potential to replace camera assistants in a large percentage of routine laparoscopic surgery. Although the robotic Freehand has been used in certain operations in urology and gynecology, there have been no published reports in robotic (single-port) hernia surgery. Methods: This study reports the first case and a series of 16 patients who underwent robotic single-port total extraperitoneal inguinal hernia repair compared to 16 consecutive cases of conventional single-port inguinal hernia repair. Patients were matched for age, sex, body mass index, American Society of Anesthesiologists classification, and types of hernia. Results: Although operation time was comparable in both, the time wasted for scope cleaning was 8.5 minutes for conventional compared to 1.5 minutes for robotic surgery. Conclusion: Robotic single-port inguinal hernia repair is feasible and efficient. This represents a further milestone in laparoscopic surgery. PMID:21985715

Intraperitoneal Bupivacaine Effect on Postoperative Nausea and Vomiting Following Laparoscopic Cholecystectomy  

PubMed Central

Background: Postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy (LC) has multifactorial etiology. Pain and use of opioids are among the important factors. Objectives: The present study aimed to evaluate the efficacy of intrapritoneal (IP) injection of bupivacaine on PONV. Patients and Methods: This was a double-blind randomized clinical trial, conducted on 66 patients aged 20-60, ASA I or II, candidates for LC. Patients were randomly assigned to two groups. Bupivacaine group received 20 mL bupivacaine 0.25% in the gallbladder bed, before and after cholecystectomy and the control group did not. The incidence of nausea and postoperative pain intensity was measured with Visual analogue scale (VAS) at 1, 2, 3 and 4 hours after operation, at rest and when coughing and changing positions. Nausea and vomiting occurrence were assessed at the same times. Results: There were no demographic data differences between groups. No differences were found between the two groups, in terms of incidence of nausea and vomiting. Furthermore, both groups were similar with respect to opioid consumption, during four hours post-operation. Conclusions: Intraperitoneal bupivacaine administration at the beginning and end of laparoscopic cholecystectomy reduced only visceral and shoulder pains at the 4th postoperative hour, but had no effect on reducing neither PONV, nor opioid demand, during the first four postoperative hours.

Two procedures at the same robotic session: robot-assisted laparoscopic radical prostatectomy and cholecystectomy.  

PubMed

A 66-year old male patient with right upper abdominal pain was diagnosed with cholelithiasis on abdominal ultrasound and elective laparoscopic cholecystectomy was recommended. His serum prostate-specific antigen was 21.3 ng/mL and underwent a 12-core transrectal ultrasound-guided prostate biopsy, which showed prostatic adenocarcinoma (Gleason score 4+4). Owing to the presence of concomitant cholelithiasis, we performed robot-assisted laparoscopic radical prostatectomy and robot-assisted laparoscopic cholecystectomy at the same session. Console time was 257 minutes. Intraoperative blood loss was 50 mL. Patient was fit to be discharged on postoperative day 2. Surgical specimen pathology showed a bilateral prostatic adenocarcinoma of Gleason score 4+3, with unilateral extracapsular extension and negative surgical margins. Currently, he is full continent with a serum prostate-specific antigen of 0.04 ng/mL on his first-month follow-up evaluation. Combined robotic approach seems to have many benefits including shorter hospital stay, decreased cost, decreased anesthesia risk, and better cosmetic results. PMID:21304371

Enlargement of umbilical incision in standard laparoscopic cholecystectomy is frequently necessary: An argument for the single incision approach?  

PubMed

Abstract Objective: Cosmetic result after cholecystectomy is up for debate. The aim of this study was to investigate the incidence and extent of enlargement of initial skin and fascia incision in standard laparoscopic cholecystectomy and to detect predictive factors for such an enlargement. Material and methods: The size of the umbilical incision was measured before and after standard laparoscopic gallbladder removal in 391 patients from August 2009 to October 2012. Predisposing factors for the need of enlargement of the umbilical incision were analysed. Results: Additional enlargement of the umbilical incision for gallbladder removal was required in 35.8% of the patients at skin level, and in 40.4% at fascia level. The median enlargement of the umbilical skin incision was 11 mm, from 25 mm to 36 mm. Gallbladder weight, total stone weight, maximum diameter of largest stone and shorter initial length of incision were independent predisposing factors for enlargement of the incision. Conclusions: In standard laparoscopic cholecystectomy the umbilical incision frequently requires secondary enlargement, especially if a large stone mass is involved. Therefore, the cosmetic result after laparoscopic cholecystectomy depends on more than only the technique used for access and the surgical technique for cholecystectomy should be chosen individually for each patient according to the stone mass.

Intestinal obstruction from midgut volvulus after laparoscopic cholecystectomy. A report of an unusual complication.  

PubMed

Congenital midgut malrotation, a rare anatomic anomaly that can lead to duodenal or small bowel obstruction, rarely is recognized beyond the first year of life. We report a case of unrecognized congenital midgut malrotation that resulted in midgut volvulus, causing intestinal obstruction and requiring emergent reoperation after laparoscopic cholecystectomy. This unusual complication, first reported in 1994, involved a 56-year-old man and resulted in cecal infarction recognized and treated on the second postoperative day. This second case describes a less acute postoperative course, with multiple bouts of partial bowel obstruction leading to two readmissions and finally resulting in a reexploration and definitive treatment on the 19th postoperative day.

Peritoneal chronic inflammatory mass formation due to gallstones lost during laparoscopic cholecystectomy.  

PubMed

We here describe the radiologic findings of peritoneal chronic abscess formation due to gallstones lost within the peritoneum during laparoscopic cholecystectomy (LC). A radiologic workup 7 months after LC revealed a soft-tissue mass with contrast enhancement, harboring internal necrosis and punctate calcium located in the Morrison's pouch. The mass exhibited restricted water molecule diffusion, absence of fat deposition, and increased F-18 fluorodeoxy-D-glucose uptake, thus mimicking a malignant tumor. The biopsy revealed an inflammatory granuloma. Another patient with similar findings was treated with percutaneous abscess drainage. Thus, radiologists should be aware of this disease condition and its imaging findings. PMID:24852678

Automatic PSO-Based Deformable Structures Markerless Tracking in Laparoscopic Cholecystectomy  

NASA Astrophysics Data System (ADS)

An automatic and markerless tracking method of deformable structures (digestive organs) during laparoscopic cholecystectomy intervention that uses the (PSO) behavour and the preoperative a priori knowledge is presented. The associated shape to the global best particles of the population determines a coarse representation of the targeted organ (the gallbladder) in monocular laparoscopic colored images. The swarm behavour is directed by a new fitness function to be optimized to improve the detection and tracking performance. The function is defined by a linear combination of two terms, namely, the human a priori knowledge term (H) and the particle's density term (D). Under the limits of standard (PSO) characteristics, experimental results on both synthetic and real data show the effectiveness and robustness of our method. Indeed, it outperforms existing methods without need of explicit initialization (such as active contours, deformable models and Gradient Vector Flow) on accuracy and convergence rate.

Initial experience with laparoscopic-assisted transvaginal cholecystectomy: a hybrid approach to natural orifice surgery.  

PubMed

Minimally invasive surgery is designed to provide a friendlier surgical therapy, in terms of faster recovery times, improved cosmetic results, and reduced postoperative pain. In recent years, a new genre for exploring the abdominal cavity without incisions has been developed. Incisionless surgery is considered the next frontier in minimally invasive surgery. The idea is to use natural orifices as the entry point to the abdomen, by using an endoscope through a transgastric, transvaginal, transvesical, or transcolonic access; hence, it is called as natural orifice transluminal endoscopic surgery (NOTES). We report our first case of laparoscopic-assisted transvaginal cholecystectomy. We support that NOTES can provide benefits in terms of reduced pain, faster recovery, and better cosmetic results compared with conventional laparoscopic surgery. PMID:20187522

Haemodynamic and end tidal CO? changes during laparoscopic cholecystectomy under general anaesthesia.  

PubMed

A prospective observational study was done on 50 patients to investigate the haemodynamic and end tidal CO? (EtCO?) changes in healthy patients without cardiopulmonary pathology during elective laparoscopic cholecystectomy in head up position under standard protocol of general anaesthesia. During surgery, intra abdominal pressure was maintained at 15 mmHg by a CO? insufflator and minute ventilation was controlled with a constant tidal volume and fixed respiratory rate. Haemodynamic parameters, EtCO?, SpO? and ECG were recorded before and after induction and positioning of the patients and at 5 minutes interval for the first 30 minutes, then 10 minutes interval for the rest of the period. Highly significant increase (p<0.001) in pulse rate, systolic, diastolic and mean arterial pressure occurred at 30 minutes after insufflations and positioning of the patient. A very highly significant (p<0.001) increase in EtCO? from the base line was at 40 minutes after insufflations and positioning of the patients. There was no change in SpO? and ECG. This study supports the significant physiological changes in terms of haemodynamic and EtCO? during laparoscopic cholecystectomy and recommends the meticulous monitoring of these parameters during the surgery and balance the benefit of laparoscopy against the intra operative risk.

Imaging of the common bile duct in patients undergoing laparoscopic cholecystectomy.  

PubMed Central

Options for managing the common bile duct during laparoscopic cholecystectomy include routine peroperative cholangiography and selected preoperative endoscopic retrograde cholangiopancreatography (ERCP). The use of these methods was reviewed in 350 patients with symptomatic gall stones referred for laparoscopic cholecystectomy. Unit A (n = 114) performed routine cystic duct cholangiography but undertook preoperative ERCP in patients at very high risk of duct stones only; unit B (n = 236) performed selected preoperative ERCP on the basis of known risk factors for duct stones. The detection rate for common bile duct stones was similar for units A and B (16% v 20%). In unit A, five of seven patients who had preoperative ERCP had duct stones. Operative cholangiography was technically successful in 90% of patients and duct stones were confidently identified in 13, one of whom went on to immediate open duct exploration. Postoperative ERCP identified duct stones in only four patients, indicating spontaneous passage in eight. In unit B, preoperative ERCP was undertaken in 76 of 236 (32%) patients and duct stones were identified in 47 (20%). Duct clearance was successful in 42 (18%) but failed in five (2%), necessitating elective open duct exploration. Both protocols for imaging the common bile duct worked well and yielded satisfactory short term results. PMID:8063230

The influence of Kinesio Taping on the effects of physiotherapy in patients after laparoscopic cholecystectomy.  

PubMed

Physiotherapy in patients after laparoscopic cholecystectomy (CHL) is impeded by postoperative pain which causes a decline in patients' activity, reduces respiratory muscles' function, and affects patients' ability to look after themselves. The objective of this work was to assess the influence of Kinesio Taping (KT) on pain level and the increase in effort tolerance in patients after CHL. The research included 63 patients after CHL. Test group and control group included randomly selected volunteers. Control group consisted of 32 patients (26 females, 6 males), test group consisted of 31 patients (22 females, 9 males). Both groups were subjected to complex physiotherapy, and control group had additional KT applications. Before surgery, during and after physiotherapy, patients were given the following tests: 100-meter walk tests, subjective pain perception assessment, and pain relief medicines intake level assessment. The level of statistical significance for all tests was established at P < 0.05. Statistical analysis showed a significant decrease in the time required to cover a 100-meter distance and a decrease in pain perception presented by significantly lower painkillers' intake in the test group in comparison with the control group. The improvement in clinical condition observed in the research indicates the efficiency of KT as a method complementing physiotherapy in patients after laparoscopic cholecystectomy. PMID:22645478

The improvement in clinical condition observed in the research indicates the efficiency of KT as a method complementing physiotherapy in patients after laparoscopic cholecystectomy. PMID:22645478

Laparoscopic cholecystectomy for acalculous cholecystitis in a neutropenic patient after chemotherapy for acute lymphoblastic leukemia  

PubMed Central

Acute acalculous cholecystitis (ACC) is most frequently reported in critically ill patients following sepsis, extensive injury or surgery. It is rather uncommon as a chemotherapy-induced complication, which is usually life-threatening in neutropenic patients subjected to myelosuppressive therapy. A 23-year-old patient with acute lymphoblastic leukemia was subjected to myelosuppressive chemotherapy (cyclophosphamide, cytarabine, pegaspargase). After the first chemotherapy cycle the patient was neutropenic and feverish; she presented with vomiting and pain in the right epigastrium. Ultrasound demonstrated an acalculous gallbladder with wall thickening up to 14 mm. The ACC was diagnosed. Medical therapy included a broad spectrum antibiotic regimen and granulocyte-colony stimulating factors. On the second day after ACC diagnosis the patient's general condition worsened. Laparoscopic cholecystectomy was performed. The resected gallbladder showed no signs of bacterial or leukemic infiltrates. The postoperative course was uneventful. In the management of neutropenic patients with ACC surgical treatment is as important as pharmacological therapy. PMID:25337176

[Cholelithiasis. Laparoscopic treatment with intracorporeal lithotripsy followed by cholecystostomy or cholecystectomy. Personal technique].  

PubMed

From November 1988 to February 1990 157 patients with gallbladder stones have been treated by a laparoscopic surgical procedure. They are 28 males and 129 females from 13 to 81 years old, 18 have had a cholecystostomy after intracorporeal lithotripsy (Lus Ultrasonic Olympus). They were placed on bile acids during 3 months. The average follow up time is 11 months. The mortality is zero and 2 mild complications occurred medically cured. 3 patients have a recurrent stone 6 month after surgery. 139 patients have had a cholecystectomy 89 after the same lithotripsy procedure seen above, 50 without prior lithotripsy. In 3 cases the laparoscopic procedure was abandoned, twice because of a sever bleeding, one for too compact surrounding adhesions. The mean follow up is 9 months. 123 were drained 1 day 16 had no drain. The mortality is zero. 2 patients without drainage developed a sub hepatic and douglas pouch abscess. They were cured by a lavage drainage laparoscopically made. 1 patient with drainage had a 7 days bile leak which disappeared spontaneously. The 136 others have had a short stay in the hospital (2-4 days) a painless post operative time. They could go back to work and sport within 1 week. They have minimal scars and no danger of incisional herniae. The magnification of the optical system enables the dissection of the cystic duct and artery easier and safer than it is by mini laparotomy mostly in obese people. At the beginning of our experience only the patients with frequent biliary colics have been selected for the laparoscopic procedure.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2149091

Effect of Transversus Abdominis Plane Block on Cost of Laparoscopic Cholecystectomy Anesthesia  

PubMed Central

Background Use of transversus abdominis plane (TAP) block for postoperative analgesia is continuously increasing. However, few studies have investigated intraoperative effects of TAP block. We aimed to study the effects of TAP block in terms of cost-effectiveness and consumption of inhalation agents. Material/Methods Forty patients undergoing laparoscopic cholecystectomy were enrolled in this study. Patients were randomly divided into 2 groups: Group 1 (n=20) patients received TAP block and Group 2 (n=20) patients did not receive TAP block. Standard anesthesia induction was used in all patients. For the maintenance of anesthesia, fractional inspired oxygen (FIO2) of 50% in air with desflurane was used with a fresh gas flow of 4 L/min. All patients were monitored with electrocardiography and for peripheral oxygen saturation (SpO2), end-tidal carbon dioxide (ET), heart rate (HR), noninvasive mean blood pressure (MBP), and bispectral index (BIS). Bilateral TAP blocks were performed under ultrasound guidance to Group 1 patients. The BIS value was maintained at between 40 and 50 during the surgery. The Dion formula was used to calculate consumption of desflurane for each patient. Results There was no difference between the groups with respect to demographic characteristics of the patients. Duration of anesthesia, surgery time, and dosage of fentanyl were similar in the 2 groups. However, the cost and consumption of desflurane was significantly lower in Group 1. Conclusions Total anesthesia consumption was lower and the cost-effectiveness of anesthesia was better in TAP block patients with general anesthesia than in non-TAP block patients undergoing laparoscopic cholecystectomy.

Elevated plasma visfatin levels correlate with conversion of laparoscopic cholecystectomy to open surgery in acute cholecystitis.  

PubMed

Visfatin correlates with inflammation and its levels in peripheral blood are associated with some inflammatory diseases. This study aimed to assess the relationship between plasma visfatin levels and conversion of laparoscopic cholecystectomy to open surgery in acute cholecystitis. One hundred and forty-six acute cholecystitis patients and 146 sex- and age-matched healthy controls were recruited and their plasma visfatin levels were determined using an enzyme immunoassay. 17 patients (11.6%) underwent conversion. Plasma visfatin levels were statistically significantly elevated in all patients (97.2±41.8ng/mL), those with (161.4±71.3ng/mL) or without conversion (88.7±26.9ng/mL), compared to controls (40.3±13.3ng/mL, all P<0.001). A linear regression analysis showed that plasma visfatin levels were positively associated with plasma C-reactive protein levels (t=0.510, P<0.001). A logistic-regression analysis showed that age [odds ratio (OR) 1.160, 95% confidence interval (CI) 1.011-1.332, P=0.035] and plasma visfatin levels (OR 1.035, 95% CI 1.005-1.066, P=0.022) appeared to be the independent predictors of conversion. A receiver operating characteristic curve analysis found that plasma visfatin levels predicted conversion with high area under curve (AUC) (AUC, 850; 95% CI, 0.781-0.903). The AUC of the visfatin concentration was similar to that of age (AUC, 0.738; 95% CI, 0.659-0.807) (P=0.188). Visfatin improved the AUC of age to 0.914 (95% CI, 0.856-0.954) (P=0.011) using a combined logistic-regression model. Thus, high plasma levels of visfatin are associated with systemic inflammation, and may independently predict conversion of laparoscopic cholecystectomy to open surgery in acute cholecystitis.

Laparoscopic cholecystectomy for severe acute cholecystitis in a patient with situs inversus totalis and posterior cystic artery.  

PubMed

Situs inversus totalis is an inherited condition characterized by a mirror-image transposition of thoracic and abdominal organs. It often coexists with other anatomical variations. Transposition of the organs imposes special demands on the diagnostic and surgical skills of the surgeon. We report a case of a 34-year-old female patient presented with left upper quadrant pain, signs of acute abdomen, and unknown situs inversus totalis. Severe acute cholecystitis was diagnosed, and an uneventful laparoscopic cholecystectomy was performed. A posterior cystic artery was identified and ligated. Laparoscopic cholecystectomy is feasible in patients with severe acute calculus cholecystitis and situs inversus totalis; however, the surgeon should be alert of possible anatomic variations.

To Study the Levels of C - Reactive Protein and Total Leucocyte Count in Patients Operated of Open and Laparoscopic Cholecystectomy  

PubMed Central

Background: The recovery from laparoscopic cholecystectomy (LC) is rapid and most of the patients are discharged on the 1st post-operative day. There is an increased concentration of certain serum proteins, known as acute-phase reactive proteins (APRP) during the post-operative period depends on the degree of tissue damage and the inflammatory reaction. There is a direct positive correlation between the concentrations of APRP, especially C-reactive protein (CRP), and the severity of inflammation. This study was done to study the levels of C - reactive protein and Total Leucocyte Count in patients operated either by Open Cholecystectomy (OC) and Laparoscopic Cholecystectomy (LC). Materials and Methods: This prospective study was conducted on 50 patients after approval from the Institutional Ethics Committee. Twenty five patients underwent open cholecystectomy and the other 25 had laparoscopic cholecystectomy. The pre and post operative concentrations of serum C-reactive protein (CRP) and total leukocyte count (TLC) were compared in both the groups. Results: There were no differences in the preoperative serum CRP and TLC concentrations – in both the groups. Serum CRP rose significantly following OC compared to that of patients who underwent LC (10.52 ± 1.96 mg% vs. 8.88 ± 1.23 mg %). There were also significant differences in the post-operative TLC ( 9.49 ± 1.05 m/mm3 for the OC group vs. 8.57 ± 1.31 m/mm3 for the LC group), and the post-operative hospital stay (5.5 ±1.5 days vs. 1.9 ± 0.9 days). There was no correlation between serum CRP concentrations and the other post-operative parameters. Conclusion: The study provided the biochemical evidence supporting the clinical observation that LC is far less traumatic to the patient than OC. PMID:25121022

Dissection by Ultrasonic Energy Versus Monopolar Electrosurgical Energy in Laparoscopic Cholecystectomy  

PubMed Central

Introduction: Laparoscopic cholecystectomy is the gold standard for management of symptomatic gallstones. Electrocautery remains the main energy form used during laparoscopic dissection. However, due to its risks, search is continuous for safer and more efficient forms of energy. This review assesses the effects of dissection using ultrasonic energy compared with monopolar electrocautery during laparoscopic cholecystectomy. Methods: A literature search of the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE, and EMBASE was performed. Studies included were trials that prospectively randomized adult patients with symptomatic gallstone disease to either ultrasonic or monopolar electrocautery dissection during laparoscopic cholecystectomy. Data were collected regarding the characteristics and methodological quality of each trial. Outcome measures included operating time, gallbladder perforation rate, bleeding, bile leak, conversion rate, length of hospital stay and sick leave, postoperative pain and nausea scores, and influence on systemic immune and inflammatory responses. For metaanalysis, the statistical package RevMan version 4.2 was used. For continuous data, Weighted Mean Difference (WMD) was calculated with 95% confidence interval (CI) using the fixed effects model. For Categorical data, the Odds Ratio (OR) was calculated with 95% confidence interval using fixed effects model. Results: Seven trials were included in this review, with a total number of 695 patients randomized to 2 dissection methods: 340 in the electrocautery group and 355 in the ultrasonic group. No mortality was recorded in any of the trials. With ultrasonic dissection, operating time is significantly shorter in elective surgery (WMD ?8.19, 95% CI ?10.36 to ?6.02, P>0.0001), acute cholecystitis (WMD ?17, 95% CI ?28.68 to ?5.32, P=0.004), complicated cases (WMD ?15, 95% CI ?28.15 to ?1.85, P=0.03), or if surgery was performed by trainee surgeons who had performed >10 procedures (P=0.043). Gallbladder perforation risk with bile leak or stone loss is lower (OR 0.27, 95% CI 0.17 to 0.42, P>0.0001 and OR 0.13, 95% CI 0.04 to 0.47, P=0.002 respectively), particularly in the subgroup of complicated cases (OR 0.24 95% CI 0.09 to 0.61, P=0.003). Mean durations of hospital stay and sick leave were shorter with ultrasonic dissection (WMD ?0.3, 95% CI ?0.51 to ?0.09, P=0.005 and WMD ?3.8, 95% CI ?6.21 to ?1.39, P=0.002 respectively), with a smaller mean number of patients who stayed overnight in the hospital (OR 0.18, 95% CI 0.03 to 0.89, P=0.04). Postoperative abdominal pain scores at 1, 4, and 24 hours were significantly lower with ultrasonic dissection as were postoperative nausea scores at 2, 4, and 24 hours. Conclusion: Based on a few trials with relatively small patient samples, this review does not attempt to advocate the use of a single-dissection technology but rather to elucidate results that could be used in future trials and analyses. It demonstrates, with statistical significance, a shorter operating time, hospital stay and sick leave, lower gallbladder perforation risk especially in complicated cases, and lower pain and nausea scores at different postoperative time points. However, many of these potential benefits are subjective, and prone to selection, and expectation bias because most included trials are unblinded. Also the clinical significance of these statistical results has yet to be proved. The main disadvantages are the difficulty in Harmonic scalpel handling, and cost. Appropriate training programs may be implemented to overcome the first disadvantage. Cost remains the main universal issue with current ultrasonic devices, which outweighs the potential clinical benefits (if any), indicating the need for further cost-benefit analysis. PMID:20412640

A risk score to predict the difficulty of elective laparoscopic cholecystectomy  

PubMed Central

Introduction Several preoperative scoring systems have been proposed to predict the difficulty of laparoscopic cholecystectomy in order to optimize the results of surgical treatment by either selection of patients for the procedure or providing an adequately experienced surgical team for a given patient. Nevertheless, none of them has achieved significant penetration into everyday practice. Aim To propose and validate a novel risk score based on the patient's history, physical examination and abdominal ultrasonography parameters. Material and methods The risk score was defined by the presence of the following risk factors: male sex, biliary colic within the last 3 weeks prior to surgery, history of acute cholecystitis treated conservatively, previous upper abdominal surgery, right upper quadrant pain, rigidity in right upper abdomen and ultrasonographic parameters – thickening of the gallbladder wall ? 4 mm, hydropic gallbladder (diameter exceeding 4.5 cm) and shrunken gallbladder. One point was allocated for each risk factor, except for previous upper abdominal surgery, which scored two. Difficulty of the surgery was assessed by operating time (OT) and the postoperative subjective evaluation score (PSES). Results Five hundred and eighty-six consecutive patients were enrolled in the prospective observational study. A significant linear correlation was observed between the risk score and measures of difficulty employed. Five levels of difficulty were defined (score 0, 1, 2, 3, ? 4) with significant differences in OT, PSES and conversion rates (p < 0.001). Conclusions The suggested risk score is designed as a simple and reliable predictive model, possibly effective to overcome the negative effect of the individual proficiency gain curve and/or to select ‘easy’ cases for day surgery, single incision laparoscopic surgery or natural orifice translumenal endoscopic surgery procedures.

Perioperative changes in oxygen saturation after ambulatory laparoscopic cholecystectomy: a retrospective analysis.  

PubMed

In the ambulatory surgical setting, patients may present with grossly abnormal oxygen saturation (Spo2) readings that, along with other disease pathology, make referral to an inpatient facility a straightforward decision. Patients presenting with unexplained slightly abnormal Spo2 readings might make evaluation as an appropriate candidate for the ambulatory setting more problematic. Little guidance is provided for these scenarios in current consensus documents, and minimal data exist regarding preoperative baseline Spo2 readings as a predictor for postoperative Spo2 readings after undergoing general anesthesia and surgery in the ambulatory care setting. A retrospective analysis was performed of all laparoscopic cholecystectomies performed at a freestanding ambulatory surgery center during 2011 (n = 56). Multiple linear regression analysis was performed to establish predictors for variability in baseline Spo2. Wilcoxon tests were used to compare preoperative baseline Spo2 readings with readings taken at discharge. Increased patient age was the only statistically significant predictor of lower baseline Spo2 levels, although no statistically significant decrease in Spo2 was found at discharge in patients above 60 years old. Males, patients who smoke, and patients whose body mass index exceeded 30 kg/m2 all demonstrated statistically significant decreases in Spo2 values at discharge home (Z = -1.947, -1.807, -1.75, P < .05).

Hemodynamic and respiratory changes during laparoscopic cholecystectomy with high and reduced intraabdominal pressure.  

PubMed

Laparoscopic cholecystectomy (lapchole) is a safe procedure. Most of the complications are operation related. The complications related to increased intraabdominal pressure (IAP) are well recognized, but not emphasized enough. The changes in physiological parameters at different IAPs were studied to evaluate the usefulness of reduced IAP in minimizing these changes. Thirty consecutive patients consisting of 16 ASA III, 2 ASA IV, and the rest ASA I and II, underwent lapchole under high and reduced IAP. The mean arterial pressure (MAP), heart rate (HR), arterial oxygen saturation (SaO2), airway pressure (AWP), and end-tidal carbon dioxide (ETCO2) were recorded before insufflating carbon dioxide (T1), with IAP of 14 mm Hg (T2) and IAP of 6 mm Hg or less (T3). At T2, MAP increased by 41.15%, AWP by 44.3%, and ETCO2 by 20.5% as compared to T1 (p < 0.001). HR and SaO2 showed no significant changes. At T3 there was an increase in MAP by 24.94%, in AWP by 10%, and ETCO2 by 10.6% with no significant changes in HR and SaO2. Thus, operating under reduced IAP may be beneficial to the patients with decreased cardiopulmonary reserve, especially while undergoing long surgical procedures. PMID:8743363

[Anesthetic management of laparoscopic cholecystectomy for a patient with Churg-Strauss syndrome: a case report].  

PubMed

Churg-Strauss syndrome (CSS) is an uncommon disease characterized by bronchial asthma, eosinophilia and systemic vasculitis. Many patients with CSS are suffering from cardiovascular disorders, neurological disorders and/or renal disorders which are associated with systemic vasculitis. Cardiac diseases are considered as the main cause of the death in patients with CSS. Steroid administration is the standard pharmacological therapy for CSS. There are very few clinical reports concerning anesthetic management for the patients with CSS. We suppose that precise perioperative managements are required for the patients with CSS, including the appropriate control of bronchial asthma and the careful treatments of disorders in cardiovascular system, neurological system and/or kidney. In addition, we believe that the steroid cover should be considered during the perioperative period of the patients with CSS. Here, we describe an anesthetic management of a 28-year-old man with CSS undergoing laparoscopic cholecystectomy. General anesthesia was induced with midazolam and fentanyl. Rocuronium was administered to facilitate tracheal intubation. After tracheal intubation, anesthesia was maintained with sevoflurane and remifentanil. Prior to the surgery, 100 mg of hydrocortisone was administered for the steroid cover. The surgery was uneventful. The patient emerged from general anesthesia smoothly, and was extubated safely.

Can single incision laproscopic cholecystectomy replace the traditional four port laproscopic approach: a review.  

PubMed

The major aim of surgeons has always been a minimalist approach towards surgery, thereby reducing the complications associated with the surgery. The gold standard treatment for cholelithiasis with cholecystitis is currently the four port laparoscopic cholecystectomy (4 PLC). Recently, a newer technique has been introduced which uses a single port, rather than the four ports, for the removal of the gall bladder laparoscopically; it is known as Single Incision Laparoscopic Cholecystectomy (SILC). This is a comparatively minimal approach towards surgery. Therefore the purpose of this review is to compare the advantages and the disadvantages of SILC versus 4PLC, and hence, to give an idea of whether SILC is ready to replace the traditional approach as the new treatment of choice.

Comparison of hemodynamic and metabolic stress responses caused by endotracheal tube and Proseal laryngeal mask airway in laparoscopic cholecystectomy  

PubMed Central

Background: We aimed to compare hemodynamic and endocrine alterations caused by stress response due to Proseal laryngeal mask airway and endotracheal tube usage in laparoscopic cholecystectomy. Materials and Methods: Sixty-three ASA I-II patients scheduled for elective laparoscopic cholecystectomy were included in the study. Patients were randomly allocated into two groups of endotracheal tube and Proseal laryngeal mask airway. Standard general anaesthesia was performed in both groups with the same drugs in induction and maintenance of anaesthesia. After anaesthesia induction and 20 minutes after CO2 insufflations, venous blood samples were obtained for measuring adrenalin, noradrenalin, dopamine and cortisol levels. Hemodynamic and respiratory parameters were recorded at the 1st, 5th, 15th, 30th and 45th minutes after the insertion of airway devices. Results: No statistically significant differences in age, body mass index, gender, ASA physical status, and operation time were found between the groups (p > 0.05). Changes in hemodynamic and respiratory parameters were not statistically significant when compared between and within groups (p > 0.05). Although no statistically significant differences were observed between and within groups when adrenalin, noradrenalin and dopamine values were compared, serum cortisol levels after CO2 insufflation in PLMA group were significantly lower than the ETT group (p = 0.024). When serum cortisol levels were compared within groups, cortisol levels 20 minutes after CO2 insufflation were significantly higher (46.1 (9.5-175.7) and 27.0 (8.3-119.4) in the ETT and PLMA groups, respectively) than cortisol levels after anaesthesia induction (11.3 (2.8-92.5) and 16.6 (4.4-45.4) in the ETT and PLMA groups, respectively) in both groups (p = 0.001). Conclusion: PLMA usage is a suitable, effective and safe alternative to ETT in laparoscopic cholecystectomy patients with lower metabolic stress. PMID:23264788

Monopolar electrocautery versus ultrasonic dissection of the gallbladder from the gallbladder bed in laparoscopic cholecystectomy: a randomized controlled trial  

PubMed Central

Background Ultrasonic dissection has been suggested as an alternative to monopolar electrocautery in laparoscopic cholecystectomy because it generates less tissue damage and may have a lower incidence of gallbladder perforation. We compared the 2 methods to determine the incidence of gallbladder perforation and its intraoperative consequences. Methods We conducted a prospective randomized controlled trial between July 2008 and December 2009 involving adult patients with symptomatic gall stone disease who were eligible for laparoscopic cholecystectomy. Patients were randomly assigned before administration of anesthesia to electrocautery or ultrasonic dissection. Both groups were compared for incidence of gallbladder perforation during dissection, bile leak, stones spillage, lens cleaning, duration of surgery and estimation of risk of gall-bladder in the presence of complicating factors. Results We included 60 adult patients in our study. The groups were comparable with respect to demographic characteristics, symptomatology, comorbidities, previous abdominal surgeries, preoperative ultrasonography findings and intraoperative complications. The overall incidence of gallbladder perforation was 28.3% (40.0% in the electrocautery v. 16.7% in the ultrasonic dissection group, p = 0.045). Bile leak occurred in 40.0% of patients in the electrocautery group and 16.7% of patients in ultrasonic group (p = 0.045). Lens cleaning time (p = 0.015) and duration of surgery (p = 0.001) were longer in the electrocautery than the ultrasonic dissection group. There was no statistical difference in stone spillage between the groups (p = 0.62). Conclusion Ultrasonic dissection is safe and effective, and it improves the operative course of laparoscopic cholecystectomy by reducing the incidence of gallbladder perforation. PMID:22854110

Methods of safe laparoscopic cholecystectomy for left-sided (sinistroposition) gallbladder: A report of two cases and a review of safe techniques?  

PubMed Central

INTRODUCTION Left-sided gallbladder is a rare anatomical variation. Usually it is discovered intra-operatively and is accompanied by anatomic variations that can prove quite challenging during laparoscopy. PRESENTATION OF CASE From a total of almost 3000 laparoscopic cholecystectomies performed in our institution, two cases of left sided gallbladder were unexpectantly identified intraoperatively. There were no indications for the ectopy preoperatively. In both cases modifications of the standard laparoscopic technique were mandatory. They were performed safely with no post-operative complications. Modifications consisted of transposition of the subxiphoid entry port and alteration in the direction of traction of the rest of the graspers. A review of the literature for methods of safe laparoscopic cholecystectomy was conducted. DISCUSSION The surgeon must be aware of the anatomic variances in the rare occasion of a left sided gallbladder, since preoperative diagnosis is very difficult. CONCLUSION Knowledge of potential hazards and modifications of laparoscopic technique is mandatory in order to avoid complications. PMID:25262322

Background. The laparoscopic cholecystectomy is a perfectly codified surgical procedure. The development of recent innovative and experimental surgical techniques Natural Orifice transluminal endoscopic surger (N.O.T.E.S.) which reduces the abdominal wall trauma leads us to develop a combined procedure of a standard dissection using miniaturised instruments already existing on the market (3 and 5?mm wide) and a gall bladder removal through a short gastrotomy Natural Orifice Specimen Extraction (N.O.S.E.). Methods. Our objective was to evaluate the safety, the feasibility, and the reproducibility of our new approach. After reviewing existing products on the market and a feasibility study, we put in place a protocol in our structure for patients on whom the procedure was performed. We carried out a gall bladder removal by a short gastrotomy, located on the anterior gastric wall, which then reduced the abdominal wall trauma and allowed them to resume normal physical activity quickly without risk of trocar site hernia. Results. We performed the procedure described in this paper on 63 patients, between April 2008 and July 2009. There were 14 men and 49 women with an average age of 46.8 years (ranging from 28 to 77) and an average BMI of 27.2. 30 patients had at least one gallstone larger than 10?mm. There was no postoperative gastric or abdominal wall complication and a fast recovery for all the patients in our study. Conclusions. This procedure is feasible, reproducible, with good results and minimal abdominal wall trauma. It is also safer than N.O.T.E.S. and endoscopic clipping and recovery, allowing normal physical activity, fast and, without risk of incisional hernia. PMID:22091353

Laparoscopic Cholecystectomy Under Spinal Anaesthesia vs. General Anaesthesia: A Prospective Randomised Study  

PubMed Central

Introduction: Laparoscopic cholecystectomy (LC) is conventionally performed under general anaesthesia (GA) in our institution. There are multiple studies which have found spinal anaesthesia as a safe alternative. We have conducted this study of LC, performed under spinal anesthesia to assess its safety and feasibility in comparison with GA. Materials and Methods: Fifty patients with symptomatic gallstone disease and American Society of Anesthesiologists status I or II were randomised to have LC under spinal (n = 25) or general (n = 25) anesthesia. Intraoperative vitals, postoperative pain, complications, recovery, and surgeon satisfaction were compared between the 2 groups. Results: In the SA group six patients (24%) complained of shoulder pain, two patients required conversion to GA (8%) as the pain did not subside with Fentanyl. None of the patients in the SA group had immediate postoperative pain at operated site. Only two (8%) patients had pain score of 4 at the operative site within eight hours requiring rescue analgesic. One patient had nausea but no vomiting (4%). All the patients (100%) in the GA group had pain at operated site immediately after surgery and their pain score ranged from 4-7, all patients received rescue analgesic before shifting to the ward. In the first 24h tramadol required as rescue in the GA group was 82±24 mg which was significantly higher than the SA group requiring only 30±33.16 mg. Although, the GA group had more patients experiencing postoperative nausea & vomiting it was not statistically significant. Conclusion: SA as the sole anaesthesia technique is feasible, safe and cost effective for elective LC. PMID:25302232

[Postoperative analgesia--a comparative study in laparoscopic cholecystectomy and lower abdominal laparotomy].  

PubMed

From September 1992 through February 1993 27 randomly chosen female patients were evaluated for differences in postoperative pain intensity (as determined by visual-analogue-scale (VAS)) and analgesic requirements via patient-controlled-analgesia (PCA), either after open lower-abdominal-laparotomy (n = 16, group 1) or after minimal-invasive-cholecystectomy (n = 11, group 2). The type of anaesthesia has been standardized, either as balanced or total intravenous anaesthesia. There were no statistically significant differences between the groups regarding to age, height, weight, intraoperative anaesthetic drug consumption, or duration of anaesthesia and surgery (205.6 vs 185.5 minutes; 139.1 vs 105.0 minutes). All patients could be extubated while still in the operation theatre. The 10-hour study period started after transfer to the recovery room. Heart- and respiratory-rate, systolic/diastolic blood pressure, endtidal pCO2, oxygen-saturation via pulsoxymetry (SaO2), and demands from PCA-pump were recorded, furthermore pain scores were determined every hour. The VAS-scores showed no significant differences between the two groups. The pain level as a whole was low, with the scores ranging from a maximum of 23.4 mm (group 1 after the first hour) to a minimum of 1.8 min (group 2 after 5, 8 an 10 hours). The overall analgesic requirements differed significantly (37.7 vs 17.3 mg piritramid, p < .01). There was a difference throughout the whole study period, although statistically significant only at the 1., 2. (p < .05), 5. and 6.-8. hour (p < .01). This study showed that pain scores were similar after laparoscopic upper or open lower abdominal surgery, both requiring adequate analgesic therapy.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8259728

Comparisons of Prediction Models of Quality of Life after Laparoscopic Cholecystectomy: A Longitudinal Prospective Study  

PubMed Central

Background Few studies of laparoscopic cholecystectomy (LC) outcome have used longitudinal data for more than two years. Moreover, no studies have considered group differences in factors other than outcome such as age and nonsurgical treatment. Additionally, almost all published articles agree that the essential issue of the internal validity (reproducibility) of the artificial neural network (ANN), support vector machine (SVM), Gaussian process regression (GPR) and multiple linear regression (MLR) models has not been adequately addressed. This study proposed to validate the use of these models for predicting quality of life (QOL) after LC and to compare the predictive capability of ANNs with that of SVM, GPR and MLR. Methodology/Principal Findings A total of 400 LC patients completed the SF-36 and the Gastrointestinal Quality of Life Index at baseline and at 2 years postoperatively. The criteria for evaluating the accuracy of the system models were mean square error (MSE) and mean absolute percentage error (MAPE). A global sensitivity analysis was also performed to assess the relative significance of input parameters in the system model and to rank the variables in order of importance. Compared to SVM, GPR and MLR models, the ANN model generally had smaller MSE and MAPE values in the training data set and test data set. Most ANN models had MAPE values ranging from 4.20% to 8.60%, and most had high prediction accuracy. The global sensitivity analysis also showed that preoperative functional status was the best parameter for predicting QOL after LC. Conclusions/Significance Compared with SVM, GPR and MLR models, the ANN model in this study was more accurate in predicting patient-reported QOL and had higher overall performance indices. Further studies of this model may consider the effect of a more detailed database that includes complications and clinical examination findings as well as more detailed outcome data. PMID:23284677

The Effect of Single-Dose Administration of Dexamethasone on Postoperative Pain in Patients Undergoing Laparoscopic Cholecystectomy  

PubMed Central

Background: Postoperative pain is considered as a reason of patient’s delay in discharge and disability aggravation. Therefore, multimodal approaches have been suggested in order to mitigate pain and decrease postoperative side effects. Objectives: The aim of this study was to evaluate analgesic effect of a single dose injection of dexamethasone on reducing postoperative pain in laparoscopic cholecystectomy. Patients and Methods: In this double-blind, prospective study, 122 patients aged 18-60 years old, whom were selected for laparoscopic cholecystectomy, were classified into two case and control groups, and 61 patients were included in each group. The case (D) group underwent general anesthesia and a single- dose intravenous injection of dexamethasone. The Control (C) group received general anesthesia and intravenous injection of normal saline. Total dose of consumed meperidine and pain intensity during first 24 hours were evaluated in both groups. Results: No significant difference existed between two groups regarding age, sex, weight and operation time. Pain intensity in group D was significantly less than group C (P < 0.01) after two, six and 12 hoursof surgery. No significant difference existed in pain intensity between two groups at the beginning of and 24 hours after the surgery (P > 0.05). Meperidine consumption in group D was significantly less than group C (P < 0.05). Conclusions: Findings of present study showed that single dose of intravenous dexamethasone, led to less pain intensity and amounts of meperidine consumption, in comparison with placebo.

Four-channel single incision laparoscopic cholecystectomy using a snake retractor: comparison between 3- and 4-channel SILC 4-channel single incision cholecystectomy  

PubMed Central

Purpose Single incision laparoscopic cholecystectomy (SILC) is a widely used method of performing cholecystectomy. A common technique used in SILC is a 3-channel method. However, exposure of Calot's triangle is limited in conventional 3-channel SILC. Therefore, we herein report the adequacy and feasibility of 4-channel SILC using a snake retractor. Methods Four hundred and fifteen SILC cases were performed between April 2010 and February 2013. We performed 326 SILC cases between April 2010 and September 2012 using the 3-channel method. We introduced a snake retractor for liver traction in October 2012, and 89 cases of 4-channel SILC using snake retractor have been performed since. Results Thirty patients (9.2%) in the 3-channel SILC group, and 23 patients (25.8%) in the 4-channel SILC group, were treated with percutaneous transhepatic gallbladder drainage insertion because of acute inflammation of the gallbladder (GB) before operation (P < 0.001). The mean operating time was 53.0 ± 25.8 minutes in the 3-channel SILC group and 51.9 ± 18.6 minutes in the 4-channel SILC group (P = 0.709). In the 3-channel SILC group, mean hospital stay was 3.0 ± 3.3 days whereas it was 2.6 ± 0.9 days in the 4-channel SILC group (P = 0.043). There were a total 9 cases (2.1%) of additional port usages, 6 cases (1.8%) in the 3-channel SILC group and 3 cases (3.4%) in the 4-channel SILC group (P = 0.411), due to cystic artery bleeding and bile leakage from gallbladder bed, but there were no open conversions. Conclusion Benign diseases of the GB can be operated on using SILC with the 4-channel method using a snake retractor. PMID:25114887

Results of treatment of patients with gallstone disease and ductal calculi by single-stage laparoscopic cholecystectomy and bile duct exploration  

PubMed Central

Introduction Choledocholithiasis is the most common cause of obstructive jaundice. Common bile duct stones are observed in 10–14% of patients diagnosed with gall bladder stones. In the case of gall bladder and common bile duct stones the procedure involves not only performing cholecystectomy but also removing the stones from bile ducts. Aim To compare the results of the treatment of patients with gallstone disease and ductal calculi by one-stage laparoscopic cholecystectomy and common bile duct exploration with two other methods: one-stage open cholecystectomy and common bile duct exploration, and a two-stage procedure involving endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy. Material and methods Between 2004 and 2011 three groups of 100 patients were treated for obstructive jaundice caused by choledocholithiasis. The first group of 42 patients underwent ERCP followed by laparoscopic cholecystectomy. The second group of 23 patients underwent open cholecystectomy and common bile duct exploration, whereas the third group of 35 patients underwent laparoscopic cholecystectomy with common bile duct exploration. The data were analysed prospectively. The methods were compared according to complete execution, bile duct clearance and complication rate. Complications were analysed according to Clavien’s Classification of Surgical Complications. The results were compared using the ANOVA statistical test and Student’s t-test in Statistica. Value of p was calculated statistically. A p-value less than 0.05 (p < 0.05) signified that groups differed statistically, whereas a p-value more than 0.05 (p > 0.05) suggested no statistically significant differences between the groups. Results The procedure could not be performed in 11.9% of patients in the first group and in 14.3% of patients in the third group. Residual stones were found in 13.5% of the patients in the first group, in 4.3% of the patients in the second group and in 6.7% of the patients in the third group. According to Clavien’s classification of complications grade II and III, we can assign the range in the first group at 21.6% for grade II and 0% for grade III, in the second group at 21.4% and 3.6% and in the third group at 6.7% and 3.3% respectively. Conclusions The use of all three methods of treatment gives similar results. One-stage laparoscopic cholecystectomy with common bile duct exploration is after all the least invasive, safer and more effective procedure. PMID:25097684

Modified technique of laparoendoscopic rendezvous ERCP during laparoscopic cholecystectomy for concomitant gallstone and common bile ductal stone.  

PubMed

Laparoendoscopic rendezvous ERCP and laparoscopic cholecystectomy (LC+ERCP/LERV) is considered an optimal approach for concomitant gallstone and common bile duct stone, but this procedure could be failed due to some technical challenges. We describe a modified technique which was adopted in 32 consecutive cases and yielded good results. A Dormia basket is inserted through cystic duct to enter duodenum and grasp the guide wire which is introduced with sphincterotome through endoscope. After pulling the basket catheter and guide wire into bile duct, the selective bile duct cannulation could be achieved by advancing sphinterotome over guide wire. An atraumatic clamp is also used to temporarily occlude proximal jejunum preventing diffuse bowel distention by air insufflation. The procedure was successfully performed in 31 cases(96.8%) , the mean operative time and endoscopic time were 82.6±19.6 min and 26.5±5.99min, respectively. This modified technique is safe, feasible and associated with short operative time. PMID:25436338

Paradoxical carbon dioxide embolism during laparoscopic cholecystectomy as a cause of cardiac arrest and neurologic sequelae: a case report  

PubMed Central

An 81-year-old male patient was scheduled for a laparoscopic cholecystectomy due to acute cholecystitis. About 50 minutes into the operation, the arterial blood pressure suddenly decreased and ventricular fibrillation appeared on the electrocardiography. The patient received cardiopulmonary resuscitation and recovered a normal vital sign. We suspected a carbon dioxide embolism as the middle hepatic vein had been injured during the surgery. We performed a transesophageal echocardiography and were able to confirm the presence of multiple gas bubbles in all of the cardiac chambers. After the operation, the patient presented a stable hemodynamic state, but showed weaknesses in the left arm and leg. There were no acute lesions except for a chronic cerebral cortical atrophy and chronic microvascular encephalopathy on the postoperative brain-computed tomography, 3D angiography and magnetic resonance image. Fortunately, three days after the operation, the patient's hemiparesis had entirely subsided and he was discharged without any neurologic sequelae.

Dexmedetomidine decreases requirement of thiopentone sodium and pentazocine followed with improved recovery in patients undergoing laparoscopic cholecystectomy  

PubMed Central

Background: Pain relief remains the most fundamental and consequential aspect of surgery for patients throughout perioperative period. Dexmedetomidine has created an interest in ?2-adrenoceptor agonists in the management of pain and hence the aim of this study was to evaluate the effectiveness of the drug in hilly population of North India. Materials and Methods: Patients, irrespective of gender, were randomly allocated to two groups, control and test, each having 30 patients. Test group received an infusion of dexmedetomidine at a rate of 0.5 ?g/kg/h 30 min before induction and 0.6 ?g/kg/h after inducing anesthesia. Control patients received a volume-matched infusion of normal saline as placebo. Approximately 2 min before induction, analgesia was provided in the form of pentazocine, 0.5 mg/kg in control and 0.3 mg/kg in the test group. Induction was performed by 2 mg/kg thiopentone sodium supplemented with intravenous boluses of 25 mg thiopentone sodium every 15 s until loss of eyelid reflex (determined every 15 s). Induction dose of thiopentone sodium and total pentazocine dose were recorded. Recovery was assessed on the clinical recovery score (CRS) scale. Results: Infusion of dexmedetomidine decreased the induction dose of thiopentone approximately by 33% and of pentazocine dose by approximately 39% in patients undergoing laparoscopic cholecystectomy. Moreover, incidence of pain was also decreased significantly. Improved CRS from 4.33 to 6.87 was noticed immediately post-operatively in dexmedetomidine group of patients. Conclusion: Infusion of dexmedetomidine during the laparoscopic cholecystectomy decreases the requirement of thiopentone sodium and pentazocine and leads to early recovery of patients. PMID:24803759

The evaluation of efficacy and safety of paravertebral block for perioperative analgesia in patients undergoing laparoscopic cholecystectomy  

PubMed Central

Background: Paravertebral block is a popular regional anesthetic technique used for perioperative analgesia in multiple surgical procedures. There are very few randomized trials of its use in laparoscopic cholecystectomy in medical literature. This study was aimed at assessing its efficacy and opioid-sparing potential in this surgery. Methods: Fifty patients were included in this prospective randomized study and allocated to two groups: Group A (25 patients) receiving general anesthesia alone and Group B (25 patients) receiving nerve-stimulator–guided bilateral thoracic Paravertebral Block (PVB) at T6 level with 0.3 ml/kg of 0.25% bupivacaine prior to induction of general anesthesia. Intraoperative analgesia was supplemented with fentanyl (0.5 ?g/kg) based on hemodynamic and clinical parameters. Postoperatively, patients in both the groups received Patient-Controlled Analgesia (PCA) morphine for the first 24 hours. The efficacy of PVB was assessed by comparing intraoperative fentanyl requirements, postoperative VAS scores at rest, and on coughing and PCA morphine consumption between the two groups. Results: Intraoperative supplemental fentanyl was significantly less in Group B compared to Group A (17.6 ?g and 38.6 ?g, respectively, P =0.001). PCA morphine requirement was significantly low in the PVB group at 2, 6, 12, and 24 hours postoperatively compared to that in Group A (4.4 mg vs 6.9 mg, 7.6 mg vs 14.2 mg, 11.6 mg vs 20.0 mg, 16.8 mg vs 27.2 mg, respectively; P <0.0001 at all intervals). Conclusion: Pre-induction PVB resulted in improved analgesia for 24 hours following laparoscopic cholecystectomy in this study, along with a significant reduction in perioperative opioid consumption and opioid-related side effects.

To drain or not to drain elective uncomplicated laparoscopic cholecystectomy? A systematic review and meta-analysis.  

PubMed

Laparoscopic cholecystectomy (LC) has largely replaced conventional cholecystectomy in the past decade. However, there are still limited data about the value of prophylactic sub-hepatic drainage for elective uncomplicated LC. We carried out a systematic review of the literature in order to perform a meta-analysis about this issue. An unrestricted search in MEDLINE, EMBASE and Cochrane Library up to 31 December 2013 was performed. Overall, seven high-methodological quality randomized controlled trials (RCTs) were included in the meta-analysis, resulting in 1310 patients totally. The incidence of abdominal collections, wound infection and overall mortality according to the presence or absence of the sub-hepatic drainage were meta-analyzed. Sub-hepatic drainage showed an increase in the abdominal collection rate in patients who underwent elective uncomplicated LC (OR 1.56, 95% CI 1.00-2.43) if compared to patients without drainage. A non-significant correlation was found in overall mortality and infection rates. The meta-analysis shows that the presence of the sub-hepatic drainage does not reduce the incidence of abdominal collection after uncomplicated LC, whereas it does not influence wound infection and mortality rates, postoperative pain and hospital stay.

Knowledge and practices of general surgeons and residents regarding spilled gallstones lost during laparoscopic cholecystectomy: a cross sectional survey  

PubMed Central

Background Gall bladder perforation, gallstone spillage and loss are commonly reported from Laparoscopic Cholecystectomy (LC). Though rare, lost gallstones can cause a variety of complications presenting variably from within 1 month to 20 years postoperatively. Our objective was to investigate knowledge and practices of surgeons and surgical residents regarding spilled gallstones lost during laparoscopic cholecystectomy. Methods An observational, cross-sectional survey, using a questionnaire based on 13 self-answered close-ended questions, was conducted at 6 different post-graduate centers in Karachi, Pakistan. Results Of the 82 participants, 23 (28%) were consultant surgeons while 59 (72%) were general surgery residents. 86% of participants were aware that stones lost during LC can cause complications. Out of the 18 reported complications presented, only 20% participants identified more than 8 complications for which they can consider lost gallstones causal. 28% of participants weren’t aware about the expected postoperative duration for presentation of complications. Only 15% of our participants expected complications beyond 5 years of the procedure. 72% of participants will not convert to open cholecystectomy to retrieve lost gallstones. While 88% of participants agreed that lost gallstones should be documented in operative notes, only 70% reported that it’s actually done in practice. 55% of participants agreed to have possibility of lost gallstones as part of the informed consent but in practice it’s included according to only 31% of participants. 68% of participants believe that patients should be informed if gallstones are lost but in actual practice only 41% participants inform patients when gallstones are lost during procedure. Conclusions We conclude that there is a dearth of awareness regarding diversity of complications from lost gallstones and about their variable postoperative duration of presentation. The practices involving lost gallstones management, documentation and patient information were found to vary widely. Proper awareness is imperative as it may compel surgeons to undertake all possible measures to retrieve spilled gallstones and progress towards better and standardized practices in managing lost gallstones.

Delayed Laparoscopic Cholecystectomy Is Safe and Effective for Acute Severe Calculous Cholecystitis in Patients with Advanced Cirrhosis: A Single Center Experience  

PubMed Central

Acute calculous cholecystitis is a common disease in cirrhotic patients. Laparoscopic cholecystectomy can resolve this problem but is performed based on the premise that the local inflammation must been controlled. An Initial ultrasound guided percutaneous transhepatic cholecystostomy may reduce the local inflammation and provide advantages in subsequent surgery. In this paper, we detailed our experience of treating acute severe calculous cholecystitis in patients with advanced cirrhosis by delayed laparoscopic cholecystectomy plus initiated ultrasound guided percutaneous transhepatic cholecystostomy and provided the analysis of the treatment effect. We hope this paper can provided a kind of standard procedure for this special disease; however, further prospective comparative randomized trials are needed to assess this treatment in cirrhotic patients with acute cholecystitis.

Paravertebral block using bupivacaine with/without fentanyl on postoperative pain after laparoscopic cholecystectomy: A double-blind, randomized, control trial  

PubMed Central

Background: Postoperative pain is one of the most common complaints after elective laparoscopic cholecystectomy. The present study was aimed to evaluate the effect of paravertebral block using bupivacaine with/without fentanyl on postoperative pain and complications after laparoscopic cholecystectomy. Materials and Methods: This study was done on 90 patients scheduled to undergo elective laparoscopic cholecystectomy. Patients were assessed in two groups: The case group received bupivacaine and fentanyl, and the control group received bupivacaine and normal saline. Primary outcomes were severity of postoperative pain at rest and during coughing. Secondary outcomes were postoperative cumulative morphine consumption and the incidence of side-effects. Results: Pain score at rest before surgery, after recovery, hour-1 and hour-6 was not significantly different between the groups. But in hour-24 cases, the pain score during coughing was significantly higher than controls. Severity of pain at rest in time points was not different between groups. The frequencies (%) of moderate pain at mentioned times in case and control groups were 64, 31, 16, 9, 0 versus 67, 16, 7, 4, and 0, respectively. Pain score during coughing was lower in controls at hour-24 in comparison with cases, but in other time points was not significant. The control group significantly received more total dose of morphine in comparison with cases group. Nausea, vomiting and hypotension were similar in groups, but pruritus was significantly different between the groups. Conclusion: Adding fentanyl to bupivacaine in paravertebral block did not significantly improve the postoperative pain and complications after laparoscopic cholecystectomy. However, further studies are needed to be done. PMID:25250301

A comparison between volume-controlled ventilation and pressure-controlled ventilation in providing better oxygenation in obese patients undergoing laparoscopic cholecystectomy  

PubMed Central

Background: The maintenance of oxygenation is a commonly encountered problem in obese patients undergoing laparoscopic cholecystectomy. There is no specific guideline on the ventilation modes for this group of patients. Although several studies have been performed to determine the optimal ventilatory settings in these patients, the answer is yet to be found. The aim of this study was to evaluate the efficacy of pressure-controlled ventilation (PCV) in comparison with volume-controlled ventilation (VCV) for maintaining oxygenation during laparoscopic cholecystectomy in obese patients. Methods: One hundred and two adult patients of ASA physical status I and II, Body Mass Index of 30–40 kg/m2, scheduled for laparoscopic cholecystectomy were included in this prospective randomized open-label parallel group study. To start with, all patients received VCV. Fifteen minutes after creation of pneumoperitoneum, they were randomized to receive either VCV (Group V) or PCV (Group P). The ventilatory parameters were adjusted accordingly to maintain the end-tidal CO2 between 35 and 40 mmHg. Respiratory rate, tidal volume, minute ventilation and peak airway pressure were noted. Arterial blood gas analyses were done 15 min after creation of pneumoperitoneum and at 20-min intervals thereafter till the end of the surgery. All data were analysed statistically. Results: Patients in Group P showed a statistically significant (P < 0.05) higher level of PaO2 and lower value of PAO2–PaO2 than those in Group V. Conclusion: PCV is a more effective mode of ventilation in comparison with VCV regarding oxygenation in obese patients undergoing laparoscopic cholecystectomy. PMID:22923828

Migration of Clips after Laparoscopic Cholecystectomy; A Case Report and Literature Review  

PubMed Central

Postcholecystectomy clip migration is rare and can lead to complications such as clip-related biliary stones. Most of such incidents have been reported as case reports. This study reviews a case of postcholecystectomy clip migration. It can occur at any time but typically occur at a median of 2 years after cholecystectomy. Clinical presentations are similar to those with primary or secondary choledocholithiasis. Most cases can be managed successfully with ERCP.

Laparoscopic cholecystectomy in situs inversus totalis with “inferior” cystic artery: A case report  

PubMed Central

A 76-year-old man with known situs inversus totalis presented with left-sided discomfort. Abdominal ultrasonography and CT scan confirmed the diagnosis of a gallstone, as well as, situs inversus; the liver and gallbladder on the left side and the spleen on the right. The biliary system was thought to be left-right reversal, mirror image in the view of drip infusion cholangiogram and MRI. Laparoscopic cholecy stectomy was safely performed, despite of unexpected aberrant cystic artery running inferior to cystic duct of situs inversus. Laparoscopic surgeon should be careful for view of reversed relationships and also existence of other anomalies. PMID:16127760

"Hook and roll technique" using an articulating hook cautery to provide a critical view during single-incision laparoscopic cholecystectomy.  

PubMed

We describe a new simple and easy technique called the "Hook and roll technique" (HRT) that uses an articulating hook cautery to provide a critical view during single incision laparoscopic cholecystectomy (SILC). A 2-cm incision is made at the umbilicus to insert three 5-mm trocars or a multichannel port. After dissection of the serosa of the dorsal and ventral sides of the gall bladder, including Calot's triangle, the angled tip of the hook cautery is inserted between the cystic artery and duct with its tip placed dorsally. The tip is then rotated in a clockwise manner to avoid bile duct injury, allowing the connective tissue between them to be hooked, coagulated and cut. This procedure is repeated several times, followed by dissection between the cystic artery and the liver bed to achieve a critical view. From December 2008 to May 2011, 121 patients underwent SILC using HRT in our hospital without any serious complications. This technique is suitable for SILC, as it is consists of simple procedures that can be performed safely and easily, even by left hand in a cross-over approach, and it allows complete dissection of Calot's triangle to achieve a critical view without using any dissector under dangerous in-line viewing.

Ambulatory laparoscopic cholecystectomy: An audit of day case vs overnight surgery at a community hospital in Japan  

PubMed Central

AIM: To evaluate the applicability and safety of ambulatory laparoscopic cholecystectomy (LC) and to compare day case and overnight stay LC. METHODS: Data were collected retrospectively and consecutively for day case and overnight stay LC patients from July 1, 2009 to April 30, 2011. Outcomes were analyzed for patient demographics, operation time, blood loss during operation and frequency and reasons for unexpected or prolonged hospitalization in each group. RESULTS: There was no hospital mortality and no patient was readmitted with serious morbidity after discharge. 50 patients received a day case LC and 19 had an overnight stay LC. There was a significant difference in age between both groups (P < 0.02). There were no significant differences between the day case LC performed (n = 41) and failed (n = 9) groups and between the day case LC performed and the one night stay LC (n = 12) groups. There was a significant difference in age between the one night stay and more nights stay LC groups (P < 0.05). Thus, elderly patients showed a tendency to like to stay in hospital rather than being a day case. The proportion of unexpected or prolonged hospitalization was not significantly different between the day case and overnight stay LC groups, when the patient’s request was excluded. CONCLUSION: Day case LC can be performed with a low rate of complications. In overnight stay patients, there are many who could be performed safely as a day case. Moreover, we need to take special care to treat elderly patients. PMID:23493831

Error traps and vasculo-biliary injury in laparoscopic and open cholecystectomy.  

PubMed

Many biliary misidentification injuries occur due to error traps-methods that work well in most circumstances but which are apt to under certain conditions. We have identified four such traps from an extensive experience in repair of biliary injuries. The most common cause of misidentification results from the "infundibular technique" error trap. This problem is usually associated with severe inflammation which hides the cystic duct and obliterates the triangle of Calot making the common hepatic duct appear to be part to the gallbladder wall. Another error trap -- the "fundus-down" cholecystectomy has been associated with injuries in which the vascular component of the injury has been even more serious than the biliary one ie, "vasculo-biliary injuries" These vasulo-biliary injuries result in hepatic infarction requiring liver resection, possibly including transplantation. As opposed to the infundibular technique error trap the fundus down error trap usually occurs at open cholecystectomy after conversion. The two other error traps are due to failure to perceive the presence of an aberrant right hepatic duct on cholangiography and injury to the common bile duct in the case of a "parallel union" cystic duct. Knowledge of these error traps and their avoidance can help to reduce the incidence of biliary injuries. PMID:18535766

Intraoperative management of a carbon dioxide embolus in the setting of laparoscopic cholecystectomy for a patient with primary biliary cirrhosis: A case report  

PubMed Central

INTRODUCTION Carbon dioxide (CO2) embolism is a rare complication of laparoscopic cholecystectomy of which both surgeons and anesthesiologists must be aware. This paper presents a case of a CO2 embolus that occurred in a patient with primary biliary cirrhosis (PBC) and discusses the possible correlation between these two events. PRESENTATION OF CASE Our patient with PBC presented with symptomatic biliary dyskinesia and was determined to be a good candidate for laparoscopic cholecystectomy. During this routine surgery a CO2 embolus entered through the altered hepatic parenchyma and progressed to the heart leading to acute hemodynamic collapse. Rapid detection and management aided in the subsequent dissolution of the embolus and recovery of the patient. DISCUSSION In patients with PBC, pathological changes that have taken place in the liver may increase the risk of CO2 embolism. Hepatic alterations that have been previously described include increased angiogenesis and vasodilation. Prior to the operation, the most appropriate method of monitoring should be determined for patients with known liver disease. CONCLUSION Both the surgical and anesthesia team must keep in mind the potential for CO2 embolism during laparoscopic surgery. It is imperative that the medical staff be aware of the risks, signs, and subsequent management so this rare, but potentially fatal event can be managed appropriately. PMID:25462045

Single-port live donor nephrectomy using a novel Curved Radius R2 Surgical System in an in vivo model.  

PubMed

Abstract Objective: Single-port laparoscopic donor nephrectomy provides low morbidity and satisfactory cosmetic results for patients. The aim of this animal study was to establish a surgical technique of single-site (LESS) living donor nephrectomy using novel curved r2 CURVE manipulators specially designed for single-port access. Material and methods: A total of six LESS nephrectomies were performed in three female pigs. r2 CURVE-instruments (Tuebingen Scientific Medical GmbH) were used providing a curved rotatable shaft, endless tip rotation, as well as 90° tip deflection. A 10 mm 30° extra long laparoscope, r2-curved Grasper, Maryland dissector and bipolar scissors were used for mobilization and dissection. Results: All LESS nephrectomies were performed successfully. Average operative time was 80 min (range, 42-149 min). No technical problems were observed. Insertion and extraction of the instruments through the single-port were easy to conduct. The diameter of the used single-port was sufficient for safe manual organ harvesting. Potential conflict between the laparoscope and the instrument handles was avoided by using an extra long laparoscope. Conclusions: The new curved and deflectable instruments showed that single-port nephrectomy using the R2 manipulators is feasible. Single-port laparoscopic nephrectomy might be more patient-friendly and improve the willingness of potential donors to donate live organs. PMID:25363462

Traumatic pseudoaneurysm of the hepatic artery after percutaneous liver biopsy and laparoscopic cholecystectomy in a patient with biliary cirrhosis: a case report  

PubMed Central

Hemobilia is a rare but recognizable complication of percutaneous transhepatic diagnostic or therapeutic procedures. The diagnosis is sometimes difficult because of the time lag between the procedure and the first symptoms, which can be intermittent. A 35-year-old woman had hemobilia after percutaneous Tru-cut biopsy of the liver followed by laparoscopic cholecystectomy. The diagnosis of hemobilia was made on clinical grounds, and a pseudoaneurysm of the right hepatic artery was detected on selective angiography. The patient was successfully treated with arterial embolization during angiography. PMID:9711166

Operative stress response is reduced after laparoscopic compared to open cholecystectomy: the relationship with postoperative pain and ileus.  

PubMed

Our objective was to determine the least invasive surgical procedure; to do this we compared postoperative pain, duration of ileus, and level of neurohormonal stress response after laparoscopic cholecystectomy (LC) and open cholecystectomy (OC). Postoperative recovery of patients was faster after LC than OC but comparison of the neurohormonal stress response after laparoscopic and open surgical procedures revealed conflicting results. Forty-one consecutive patients with noncomplicated gallstones were randomized for LC (N = 25) and OC (N = 16). The stress level was evaluated in patients before surgery by the Hamilton anxiety scale. Postoperative pain was assessed by a visual analogic scale (VAS) pain score and by the amount of analgesic drugs (propacetamol) administered, while the duration of ileus was determined by the delay between surgery and the time to first passage of flatus as well by the colonic transit time (CTT) measured by radiopaque markers. Plasma concentrations of anti-diuretic hormone (ADH), adrenocorticotropic hormone (ACTH), beta-endorphin (BE), neurotensin (NT), and aldosterone (Ald) were measured before and during surgery as well as 2 and 5 hr after the surgery (D0) and on the day following surgery (D1). Urinary cortisol (uCOR) and urinary catecholamine metabolites were assessed before surgery, during D0, and on D1. Patient characteristics, the duration of surgery, and the doses of anesthetic drugs were not different in LC and OC. In LC patients the VAS pain score and the doses of postoperative antalgics were lower (P < 0.05), the time to first passage of flatus was shorter (P < 0.001), and the CTT tended to be shorter (54 +/- 12 hr vs 81 +/- 17) compared to OC patients. Patients who required the highest doses of postoperative antalgics had the longest delay to first passage of flatus (P < 0.01). During surgery, all neurohormonal parameters increased compared to the preoperative period (P < 0.05), and only plasma NT concentrations were lower during LC than OC (P < 0.05). During the postoperative period, ACTH, BE, Aid, catecholamines, and uCOR concentrations were lower in LC than in OC (P < 0.05). Concentrations of hormonal parameters were higher when the duration of surgery increased (P < 0.05). A greater need for propacetamol to relieve pain was associated with a greater increase in BE, ACTH, and urinary catecholamine levels (P < 0.05-P < 0.005). When the time to first passage of flatus was delayed, levels of BE, ACTH, and catecholamines and NT concentrations were increased (P < 0.05-P < 0.005). In conclusion, LC is less invasive because this surgical procedure induces a shorter neurohormonal stress response than OC, even if the peroperative response is not different. Postoperative pain levels and the duration of ileus are associated with BE, ACTH, and catecholamine levels and NT concentrations, suggesting the importance of hormones in postoperative functional recovery.

Cost-effectiveness of elective laparoscopic cholecystectomy versus observation in older patients presenting with mild biliary disease.  

PubMed

Our objective was to determine the probability threshold for recurrent symptoms at which elective cholecystectomy compared to observation in older patients with symptomatic cholelithiasis is the more effective and cost-effective option. We built a decision model of elective cholecystectomy versus observation in patients >65 presenting with initial episodes of symptomatic cholelithiasis that did not require initial hospitalization or cholecystectomy. Probabilities for subsequent hospitalization, emergency cholecystectomy, and perioperative complications were based on previously published probabilities from a 5 % national sample of Medicare patients. Costs were estimated from Medicare reimbursements and from the Healthcare Cost and Utilization Project. Utilities (quality-adjusted life years, QALYs) were obtained from established literature estimates. Elective cholecystectomy compared to observation in all patients was associated with lower effectiveness (-0.10 QALYs) and had an increased cost of $3,422.83 per patient at 2-year follow-up. Elective cholecystectomy became the more effective option when the likelihood for continued symptoms exceeded 45.3 %. Elective cholecystectomy was both more effective and less costly when the probability for continued symptoms exceeded 82.7 %. An individualized shared decision-making strategy based on these data can increase elective cholecystectomy rates in patients at high risk for recurrent symptoms and minimize unnecessary cholecystectomy for patients unlikely to benefit.

Acute cholecystitis in high risk surgical patients: percutaneous cholecystostomy versus laparoscopic cholecystectomy (CHOCOLATE trial): Study protocol for a randomized controlled trial  

PubMed Central

Background Laparoscopic cholecystectomy in acute calculous cholecystitis in high risk patients can lead to significant morbidity and mortality. Percutaneous cholecystostomy may be an alternative treatment option but the current literature does not provide the surgical community with evidence based advice. Methods/Design The CHOCOLATE trial is a randomised controlled, parallel-group, superiority multicenter trial. High risk patients, defined as APACHE-II score 7-14, with acute calculous cholecystitis will be randomised to laparoscopic cholecystectomy or percutaneous cholecystostomy. During a two year period 284 patients will be enrolled from 30 high volume teaching hospitals. The primary endpoint is a composite endpoint of major complications within three months following randomization and need for re-intervention and mortality during the follow-up period of one year. Secondary endpoints include all other complications, duration of hospital admission, difficulty of procedures and total costs. Discussion The CHOCOLATE trial is designed to provide the surgical community with an evidence based guideline in the treatment of acute calculous cholecystitis in high risk patients.

Effects of low dose dexmedetomidine infusion on haemodynamic stress response, sedation and post-operative analgesia requirement in patients undergoing laparoscopic cholecystectomy  

PubMed Central

Background and Aim: Dexmedetomidine is a ?2 agonist with sedative, sympatholytic and analgesic properties and hence, it can be a very useful adjuvant in anaesthesia as stress response buster, sedative and analgesic. We aimed primarily to evaluate the effects of low dose dexmedetomidine infusion on haemodynamic response to critical incidences such as laryngoscopy, endotracheal intubation, creation of pneumoperitoneum and extubation in patients undergoing laparoscopic cholecystectomy. The secondary aims were to observe the effects on extubation time, sedation levels, post-operative analgesia requirements and occurrence of adverse effects. Methods: Sixty patients of American Society of Anaesthesiologists(ASA) physical grades I and II undergoing laparoscopic cholecystectomy were randomly allocated into three groups of 20 patients each. Group NS patients received normal saline, Group Dex 0.2 and Group Dex 0.4 patients received dexmedetomidine infusion at 0.2 mcg/kg/h and 0.4 mcg/kg/h respectively, starting 15 min before induction and continued till end of surgery. Parameters noted were pulse rate, mean arterial pressure, oxygen saturation, post-operative sedation and analgesia requirements. SPSS 15.0 version software was used for statistical analysis. ANOVA test for continuous variables, post-hoc test for intergroup comparison, and Chi-square test for discrete values were applied. Results: In Group NS significant haemodynamic stress response was seen following laryngoscopy, tracheal intubation, creation of pneumoperitoneum and extubation. In dexmedetomidine groups, the haemodynamic response was significantly attenuated. The results, however, were statistically better in Dex 0.4 group compared with Dex 0.2 group. Post-operative 24 hour analgesic requirements were much less in dexmedetomidine groups. No significant side effects were noted. Conclusion: Low dose dexmedetomidine infusion in the dose of 0.4 mcg/kg/h effectively attenuates haemodynamic stress response during laparoscopic surgery with reduction in post-operative analgesic requirements.

Laparoscopic cholecystectomy for melanoma metastatic to the gallbladder: is it an adequate surgical procedure? Report of a case and review of the literature  

PubMed Central

Background Only 2% to 4% of patients with melanoma will be diagnosed with gastrointestinal metastasis during the course of their disease. The most common sites of gastrointestinal metastases from melanoma include the small bowel (35%–67%), colon (9%–15%) and stomach (5%–7%), with a median survival of 6–10 months after surgery, and 18% survival at five years. Metastatic melanoma to the gallbladder is extremely rare and it is associated with a very poor prognosis. Case presentation We report a case of a 54-year old man presented to observation with diagnosis of 6.1 mm thick, Clark's level IV, ulcerated melanoma of the trunk, developing in the course of the disease metastatic involvement of the gallbladder as first site of recurrence, treated by laparoscopic cholecystectomy. To date only few cases of patients with metastatic melanoma of the gallbladder treated by this surgical procedure have been reported in literature. Conclusion Gallbladder metastasis represents a rare event as a first site of recurrence. It must be considered a possible expression of systemic disease also despite radiological absence of other metastatic lesions. Laparoscopic approach has a possible therapeutic role, but open surgery has also a concomitant diagnostic purpose because gives the possibility of manual exploration of abdominal cavity, useful particularly to reveal bowel metastatic lesions, not easily identifiable by preoperative imaging examinations.

Robotic single-site combined cholecystectomy and hysterectomy: Advantages and limits  

PubMed Central

INTRODUCTION Robotic single-site surgery (RSS) represents the latest innovation for clinical use of single incision surgery. Several applications have been reported in urology, general surgery and gynecology with potential application in benign cases as well as in oncology. PRESENTATION OF CASE To further explore potential applications of RSS, we present the first case reported in the literature of combined cholecystectomy and total hysterectomy using the da Vinci Si single-port platform (Intuitive Surgical Inc., Sunnyvale, CA). DISCUSSION A critical description of the procedure with potential advantages and limitations of the current platform for combined surgical procedure is provided. CONCLUSION Robotics may facilitate the widespread diffusion of single incision surgery, overcoming current laparoscopic and LESS limitations. However, the available robotic platform still has technical features that will limit its uptake amongst surgeons and further technological development is needed for a wider diffusion of single incision surgery.

Symptomatic cholecystolithiasis after cholecystectomy  

PubMed Central

A 43-year-old woman was admitted to the gastroenterology department with colicky pain in the upper abdomen. Four years earlier, she had undergone a laparoscopic cholecystectomy because of cholecystitis. She recognised her current complaints from that previous episode. An endoscopic retrograde cholangiopancreatography showed a cavity with a diameter of 2?cm which contained multiple concrements near the liver hilus. An elective surgical exploration was performed. Near the clip of the previous cholecystectomy a bulging of the biliary tract with its own duct was visualised and resected. Histological examination of this “neo” gallbladder showed that the bulging was consistent with the formation of a reservoir secondary to bile leakage, probably caused by a small peroperative lesion of the common bile duct during the previous cholecystectomy. In conclusion, our patient presented with colicky pain caused by concrements inside a ‘neo’ gallbladder. PMID:23362056

Surgical robot system for single-port surgery with novel joint mechanism.  

PubMed

Single-port surgery is a new surgical method performed by inserting several surgical tools and a laparoscope through an umbilical incision. Compared with conventional laparoscopic surgery, the smaller incision in this procedure produces a lower amount of trauma, which leads to shorter hospitalization. However, with the current laparoscopic tools and surgical robots, the surgeon must overcome several difficulties, such as a limited range of motion and collisions between the surgical instruments and the laparoscope. This paper proposes a new surgical robot system for single-port surgery that uses a novel joint mechanism. The proposed joint mechanism is suitable for surgical instruments with multiple degrees of freedom (DOF). Thus, it can prevent hysteresis of the joint and achieve more accurate motion with a large force. A 6-DOF surgical instrument with this joint mechanism can avoid collisions between surgical tools or arms and approach the surgical target more easily than a conventional straight surgical tool. The external arm with 2-DOF passive joints can extend the workspace of the system during surgery. Preliminary tests and validations were performed with a prototype of the system. PMID:23358948

A Modified Technique Reduced Operative Time of Laparoendoscopic Rendezvous Endoscopic Retrograde Cholangiopancreatography Combined with Laparoscopic Cholecystectomy for Concomitant Gallstone and Common Bile Ductal Stone  

PubMed Central

Laparoendoscopic rendezvous (LERV) endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC+ERCP/LERV) are considered an optimal approach for concomitant gallstones and common bile duct stones. The rendezvous technique is essential for the success of procedure. We applied two different LERV techniques, traditional technique and modified technique, in 60 consecutive cases from January 2011 to November 2012. 32 cases who underwent modified technique (group 1) from February 2012 to November 2012 were retrospectively compared to 28 cases (group 2) who underwent traditional technique from January 2011 to January 2012. There was no significant difference between two groups with respect to preoperative demographic features. Although the difference was not statistically significant, the procedure was successfully performed in 31 cases (96.9%) in group 1 and 24 cases (86.2%) in group 2. The mean operative time and time of endoscopic part were 82.6?±?19.6?min and 26.5?±?5.99?min in group 1 which were significantly shorter than those in group 2 (118.0?±?23.1?min and 58.7?±?13.3?min, resp.). There was no postoperative pancreatitis and mortality in both groups. The mean hospital stay, blood loss, incidence of complications, and residual stone were of no difference in both groups. This study proved that this modified technique can effectively reduce the operative time and time of endoscopic part of LC+ERCP/LERV compared with traditional technique. PMID:25024701

The effects of intraperitoneal local anesthetic on analgesic requirements and endocrine response after laparoscopic cholecystectomy: a randomized double-blind controlled study.  

PubMed

This randomized double-blind placebo-controlled study was designed to evaluate the effects on postoperative pain of the local anesthetic, 0.5% bupivacaine with epinephrine, sprayed hepatodiaphragmatically under the surgeon's direct view during laparoscopic cholecystectomy. Metabolic endocrine responses to surgery (glucose and cortisol) and nonsteroidal anti-inflammatory drug requirements were investigated, as well as the presence of nausea, vomiting, and sweating. Local anesthetics or placebo solutions were given as follows. Immediately following the creation of a pneumoperitoneum, surgeons sprayed the first 20 mL of solution (S1), and an additional 20 mL of solution (S2) was sprayed at the end of the operation. Patients were classified into three groups (14 patients per group). Group A received 20 mL of saline during both S1 and S2, group B received 20 mL of saline during S1 and 20 mL of bupivacaine during S2, and group C received 20 mL of bupivacaine during both S1 and S2. The degree of postoperative pain was assessed using the visual analogue scale (VAS) and the verbal rating scale (VRS) on arrival in the recovery room and subsequently at time intervals of 4 h, 8 h, 12 h, and 24 h. The results of this study indicate a significant decrease of postoperative pain in patients treated with local anesthetic. VAS and VRS pain scores, as well as respiratory rate and analgesic requirements, were significantly lower in group C. The postoperative plasma cortisol level in group C was significantly lower than in groups A and B. PMID:7881144

Comparison between lornoxicam quick-release and parecoxib for post-operative analgesia after laparoscopic cholecystectomy: A prospective randomized, placebo-controlled trial  

PubMed Central

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are valuable for post-operative pain as they reduce the use of opioids. Cyclooxygenase-2 inhibitors and traditional NSAIDs can be used. This is a prospective, randomized, placebo-controlled trial to study the efficacy and the safety of the oral administration of lornoxicam quick release tablets versus intravenously administered parecoxib for the management of pain after laparoscopic cholecystectomy (LC). Materials and Methods: One hundred and eight patients, American Society of Anesthesiologists I-II, were randomized to either group A (n = 36): Lornoxicam quick-release 8 mg PO, group B (n = 36): Parecoxib 40 mg intravenous (IV) or group C (n = 36) placebo, for post-operative analgesia, 30 min before the operation and 12 and 24 h post-operatively. All patients received a standard dose of meperidine 1 mg/kg intramuscularly before the incision and post-operatively as rescue analgesia, when visual analog scale (VAS) pain score was <4. Pain at rest and on movement was assessed at 20 min, 3, 6, 12, 18 and 24 h post-operatively. Total meperidine administration and adverse events were also recorded. Results: There were significantly lower VAS pain scores at 20 min, 3, 6, 12 and 18 h at rest or with movement in the lornoxicam quick release and parecoxib groups compared with the placebo group. The number of patients requiring rescue analgesia (meperidine) was significantly higher in the placebo group (P = 0.001). The average dose of meperidine administered was significantly higher in the placebo group, both at 20 min (P = 0.013/0.007) and 24 h (P = 0.037/0.023) post-operatively. VAS scores and meperidine requirements were similar in patients who received lornoxicam or parecoxib. Conclusions: Parecoxib 40 mg IV and lornoxicam quick-release 8 mg PO every 12 h are equivalent adjuvant analgesics with a greater efficacy than placebo for post-operative analgesia in patients undergoing LC.

During July 1992 to February 1993 we performed 14 such procedures. Ages ranged from 46-83 years (mean, 68). In all cases the indication for surgery was neoplasm of the colon. 8 of the tumors were located in the right colon and 6 in the sigmoid. Procedures performed were laparoscopic-assisted right hemicolectomy with a biofragmentable anastomotic ring or laparoscopic-assisted sigmoidectomy with end-to-end anastomosis. In 1 operation we combined laparoscopic cholecystectomy with laparoscopic right hemicolectomy. Operation time varied from 90-130 min (mean, 100 min). In our opinion the procedure is as radical as standard laparotomy with the number of lymph nodes per specimen ranging from 4-10 (mean, 7); the surgical margins were free of tumor in all cases. There was less pain in the postoperative period than with the standard procedure and the average time from operation to discharge was 7 days (range, 5-9). Complications included 1 fatality due to postoperative myocardial infarction, and 1 case of duodenal perforation which was sutured during the operation. We conclude that laparoscopic-assisted right hemicolectomy and laparoscopic sigmoidectomy are feasible for carcinoma, and that recovery is quicker and with less pain. However, we need a larger series and long-term follow-up to conclude whether the laparoscopic assisted technic is an adequate operation in cases of cancer. PMID:8144081

Cholecystectomy in octogenarians: be careful.  

PubMed

Cholecystectomy is the standard treatment for symptomatic gallstone or acute cholecystitis, and a growing number of elderly patients are undergoing resection. The aim of this study is to evaluate the clinical outcome of cholecystectomy in elderly patients. We retrospectively reviewed the medical records of 337 patients with symptomatic gallstone or acute cholecystitis who underwent cholecystectomies between January 2011 and June 2013. Perioperative data were compared between octogenarians and younger patients. A subgroup undergoing cholecystectomy for acute cholecystitis (n = 146, 43.3 %) was further analyzed. The octogenarian group included 34 patients (10.1 %), while the younger patient group included 303 patients (89.9 %). The octogenarian group was associated with higher rates of comorbidities and acute cholecystitis. The octogenarian group had significantly low laparoscopic completed rates, high postoperative complication rates, and longer postoperative hospital stays. Among the acute cholecystitis group, 24 patients (16.4 %) were octogenarians and 122 patients (83.6 %) were younger patients. No significant difference was found in the morbidity and postoperative hospital stay between the two groups. Only one patient (0.3 %), an octogenarian, died of pneumonia. Cholecystectomy for symptomatic gallstone or acute cholecystitis can be safely performed even in octogenarians. However, care should be taken because they have comorbidities and limited functional reserves. PMID:25266894

Single-Port Thoracic Surgery: A New Direction  

PubMed Central

Single-port video-assisted thoracic surgery (VATS) has slowly established itself as an alternate surgical approach for the treatment of an increasingly wide range of thoracic conditions. The potential benefits of fewer surgical incisions, better cosmesis, and less postoperative pain and paraesthesia have led to the technique’s popularity worldwide. The limited single small incision through which the surgeon has to operate poses challenges that are slowly being addressed by improvements in instrument design. Of note, instruments and video-camera systems that are narrower and angulated have made single-port VATS major lung resection easier to perform and learn. In the future, we may see the development of subcostal or embryonic natural orifice translumenal endoscopic surgery access, evolution in anaesthesia strategies, and cross-discipline imaging-assisted lesion localization for single-port VATS procedures.

Laparoendoscopic single-site cholecystectomy in a pregnant patient  

PubMed Central

Feasibility and safety of laparoscopic cholecystectomy during pregnancy for patients with symptomatic or complicated gallstone disease is well established. Laparoendoscopic single-site cholecystectomy (LESS-chole) is a new modality in which the entire surgery is undertaken via a transumbilical incision. We describe a 33-year-old patient who underwent a LESS-chole in the 20th week of pregnancy for gallstone disease complicated by episodes of obstructive jaundice and acute pancreatitis. This is the first reported case of LESS-chole performed using conventional laparoscopic instruments. The technical aspects as well as the various perioperative measures utilized to undertake this procedure safely are outlined. PMID:24250067

The voice of Holland: Dutch public and patient's opinion favours single-port laparoscopy  

PubMed Central

INTRODUCTION: Single-port laparoscopy is prospected as the future of minimal invasive surgery. It is hypothesised to cause less post operative pain, with a shorter hospitalisation period and improved cosmetic results. Population- and patient-based opinion is important for the adaptation of new techniques. This study aimed to assess the opinion and perception of a healthy population and a patient population on single-port laparoscopy compared with conventional laparoscopy. MATERIALS AND METHODS: An anonymous 33-item questionnaire, describing conventional and single-port laparoscopy, was given to 101 patients and 104 healthy volunteers. The survey participants (median age 44 years; range 17-82 years) were asked questions about their personal situation and their expectations and perceptions of the two different surgical techniques; conventional multi-port laparoscopy and single-port laparoscopy. RESULTS: A total of 72% of the participants had never heard of single-port laparoscopy before. The most important concern in both groups was the risk of surgical complications. When complication risks remain similar, 80% prefers single-port laparoscopy to conventional laparoscopy. When the risk of complications increases from 1% to 10%, 43% of all participants prefer single-port laparoscopy. A total of 70% of the participants are prepared to receive treatment in another hospital if single-port surgery is not performed in their hometown hospital. The preference for single-port approach was higher in the female population. CONCLUSION: Although cure and safety remain the main concerns, the population and patients group have a favourable perception of single-port surgery. The impact of public opinion and patient perception towards innovative techniques is undeniable. If the safety of the two different procedures is similar, this study shows a positive attitude of both participant groups in favour of single-port laparoscopy. However, solid scientific proof for the safety and feasibility of this new surgical technique needs to be obtained before this procedure can be implemented into everyday practice. PMID:25013327

Laparoscopically guided bilateral pelvic lymphadenectomy  

NASA Astrophysics Data System (ADS)

Pelvic node dissection has gained widespread acceptance as the final staging procedure in patients with normal acid phospatase and bone scan free of metastatic disease prior to definitive therapy for cure. However, the procedure has had a high morbidity (20-34%) and a major economic impact on the patient due to lengthy hospitalization and recuperative time. The development of laparoscopic biopsy techniques suggests that the need for open surgical lymphadenectomy may be reduced by a laparoscopically performed lymphadenectomy. The goal of this report is to investigate the possibility of laparoscopic pelvic lymphadenectomy in an animal model. Our interest in laparoscopy is based on the ability of this technique to permit tissue removal without the need for major incisions. In laparoscopic cholecystectomy and laparoscopic appendectomy, the surgical procedure is essentially unaltered. The diseased organ is removed and there is no need for a large abdominal incision.

Early Outcomes of Single-Port Video-Assisted Thoracic Surgery for Primary Spontaneous Pneumothorax  

PubMed Central

Background Recently, single-port video-assisted thoracic surgery (VATS) has been proposed as an alternative to the conventional three-port VATS for primary spontaneous pneumothorax (PSP). The aim of this study is to evaluate the early outcomes of the single-port VATS for PSP. Methods VATS was performed for PSP in 52 patients from March 2012 to March 2013. We reviewed the medical records of these 52 patients, retrospectively. Nineteen patients underwent the conventional three-port VATS (three-port group) and 33 patients underwent the single-port VATS (single-port group). Both groups were compared according to the operation time, number of wedge resections, amount of chest tube drainage during the first 24 hours after surgery, length of chest tube drainage, length of hospital stay, postoperative pain score, and postoperative paresthesia. Results There was no difference in patient characteristics between the two groups. There was no difference in the number of wedge resections, operation time, or amount of drainage between the two groups. The mean lengths of chest tube drainage and hospital stay were shorter in the single-port group than in the three-port group. Further, there was less postoperative pain and paresthesia in the single-port group than in the three-port group. These differences were statistically significant. The mean size of the surgical wound was 2.10 cm (range, 1.6 to 3.0 cm) in the single-port group. Conclusion Single-port VATS for PSP had many advantages in terms of the lengths of chest tube drainage and hospital stay, postoperative pain, and paresthesia. Single-port VATS is a feasible technique for PSP as an alternative to the conventional three-port VATS in well-selected patients. PMID:25207248

[Optimization of cholecystectomy method in patients with professional diseases of respiratory organs].  

PubMed

Results of cholecystectomy performance were analyzed in 99 patients with a biliary calculous disease, the course of which have become complicated by cholecystitis occurrence, in 49 of them professional diseases of respiratory organs, including silicosis, antracosis, were registered. Estimating results of laparoscopic and open cholecystectomy, we have established, that carboperitoneum in laparoscopic cholecystectomy impacts negatively the course of early postoperative period, what manifests with hemodynamic and respiratory disorders. The level of fibronectin and endotelin--1 in the blood plasm directly depends on the respiratory disorders severity and may be applied as a test for respiratory dysfunction. The method of cholecystectomy in patients, suffering professional diseases of respiratory organs, must be selected, depending on severity of functional disorders of respiratory organs. PMID:25417283

Laparoscopic infrared imaging.  

PubMed

A system was developed to determine the potential role of infrared imaging as a tool for localizing anatomic structures and assessing tissue viability during laparoscopic surgical procedures. A camera system sensitive to emitted energy in the midinfrared range (3-5 micron) was incorporated into a two-channel visible laparoscope. Laparoscopic cholecystectomy, dissection of the ureter, and assessment of bowel perfusion were performed in a porcine model with the aid of this infrared imaging system. Inexperienced laparoscopists were asked to localize and differentiate structures before dissection using the visible system and then using the infrared system. Assessment of bowel perfusion was also conducted using each system. Infrared imaging proved to be useful in differentiating between blood vessels and other anatomic structures. Differentiation of the cystic duct and arteries and transperitoneal localization of the ureter were successful in all instances using the infrared system when use of the visible system had failed. This system also permitted assessment of bowel perfusion during laparoscopic occlusion of mesenteric vessels. These initial studies demonstrate that infrared imaging may improve the differentiation and localization of anatomic structures and allow assessment of physiologic parameters such as perfusion not previously attainable with visible laparoscopic techniques. It may thus potentially be a powerful adjunct to laparoscopic surgery. PMID:9373300

Towards scar-free surgery: An analysis of the increasing complexity from laparoscopic surgery to NOTES  

PubMed Central

Background NOTES is an emerging technique for performing surgical procedures, such as cholecystectomy. Debate about its real benefit over the traditional laparoscopic technique is on-going. There have been several clinical studies comparing NOTES to conventional laparoscopic surgery. However, no work has been done to compare these techniques from a Human Factors perspective. This study presents a systematic analysis describing and comparing different existing NOTES methods to laparoscopic cholecystectomy. Methods Videos of endoscopic/laparoscopic views from fifteen live cholecystectomies were analyzed to conduct a detailed task analysis of the NOTES technique. A hierarchical task analysis of laparoscopic cholecystectomy and several hybrid transvaginal NOTES cholecystectomies was performed and validated by expert surgeons. To identify similarities and differences between these techniques, their hierarchical decomposition trees were compared. Finally, a timeline analysis was conducted to compare the steps and substeps. Results At least three variations of the NOTES technique were used for cholecystectomy. Differences between the observed techniques at the substep level of hierarchy and on the instruments being used were found. The timeline analysis showed an increase in time to perform some surgical steps and substeps in NOTES compared to laparoscopic cholecystectomy. Conclusion As pure NOTES is extremely difficult given the current state of development in instrumentation design, most surgeons utilize different hybrid methods – combination of endoscopic and laparoscopic instruments/optics. Results of our hierarchical task analysis yielded an identification of three different hybrid methods to perform cholecystectomy with significant variability amongst them. The varying degrees to which laparoscopic instruments are utilized to assist in NOTES methods appear to introduce different technical issues and additional tasks leading to an increase in the surgical time. The NOTES continuum of invasiveness is proposed here as a classification scheme for these methods, which was used to construct a clear roadmap for training and technology development. PMID:24902811

Combined Laparoscopic Treatment of Polycystic Ovary Disease and Gallstones  

PubMed

Laparoscopic surgery has largely replaced laparotomy in the management of both polycystic ovary disease (PCOD) and gallstones. The number of patients with a combination of these disorders has increased. From 1991 to 1996, 908 patients underwent laparoscopic cholecystectomy. In 29 women of reproductive age (18-41 yrs) with PCOD and gallstones, we performed combined laparoscopic cholecystectomy and various procedures on the ovaries (15 wedge resections, 8 multiple ovariotomies by thermocoagulation incisions, 5 electrosurgical coagulations of the ovaries). All operations were performed by the usual approach for laparoscopic cholecystectomy, and in only four women did we place a supplemental cannula. The diagnosis of PCOD was established preoperatively in 22 women, but in 6 it was an incidental finding during laparoscopic inspection of abdominal cavity. We suggest that one-stage laparoscopic cholecystectomy and procedures on the ovaries may be performed with single-puncture technique. Performing the procedures simultaneously has the advantages of minor surgical trauma, much less adhesion formation, and ability to treat hormonal disorders and infertility. For best results in women with combined PCOD and gallstones, the joint participation of abdominal surgeon and gynecologist is preferred. PMID:9074124

Laparoscopic use of laser and monopolar electrocautery  

NASA Astrophysics Data System (ADS)

Most general surgeons are familiar with monopolar electrocautery, but few are equally comfortable with laser dissection and coagulation. At courses across the country, surgeons are being introduced to laparoscopy and laser use in one and two day courses, and are certified from that day forward as laser laparoscopists. Some surgeons are told that laser and electrosurgery may be equally acceptable techniques for performance of laparoscopic surgery, but that a surgeon may double his patient volume by advertising 'laser laparoscopic cholecystectomy.' The sale of certain lasers has skyrocketed on the basis of such hype. The only surprise is that laparoscopic cholecystectomy complications occurring in this country seem to be more closely related to the laparoscopic access and visualization than to the choice of laser of electrocautery as the preferred instrument for thermal dissection. The purpose of this article is to: 1) Discuss the physics and tissue effects of electrosurgery and laser; 2) compare the design and safety of electrosurgical and laser delivery systems; and 3) present available data comparing laser and electrocautery application in laparoscopic cholecystectomy.

Laparoscopic cholecystostomy for acute acalculous cholecystitis.  

PubMed

Acute acalculous cholecystitis (AAC) can occur in up to 18% of severely injured patients. Diagnosis is made by positive ultrasound findings of gallbladder sludge, hydrox, and wall thickening. There may also be recent-onset jaundice, positive ultrasound induced Murphy's sign, and unexplained sepsis. Mortality can be as high as 50%. Laparoscopic confirmation was obtained in six ICU trauma patients when omentum was drawn up over a distended gallbladder. Laparoscopic cholecystectomy (LC) was done by first directly decompressing the gallbladder through the fundus. This trocar was replaced by a 16 French Foley catheter passed through an Endoloop into the gallbladder and secured by tightening the loop around a cuff of gallbladder. Sepsis resolved in all cases. Only one required subsequent laparoscopic cholecystectomy. LC has a low morbidity and may be life saving during the early stages of AAC. It is not indicated in gangrene or perforation of the gallbladder. PMID:8662413

Single-Port Parastomal Hernia Repair by Using 3-D Textile Implants  

PubMed Central

Background: Parastomal hernias (PSHs) are a frequent complication and remain a surgical challenge. We present a new option for single-port PSH repair with equilateral stoma relocation using preshaped, prosthetic 3-dimensional implants and flat mesh insertion in intraperitoneal onlay placement for additional augmentation of the abdominal wall. Methods: We describe our novel technique in detail and performed an analysis of prospectively collected data from patients who underwent single-port PSH repair, focusing on feasibility, conversions, and complications. Results: From September 2013 to January 2014, 9 patients with symptomatic PSHs were included. Two conversions to reduced-port laparoscopy using a second 3-mm trocar were required because of difficult adhesiolysis, dissection, and reduction of the hernia sac content. No major intra- or postoperative complications or reoperations were encountered. One patient incurred a peristomal wound healing defect that could be treated conservatively. Conclusion: We found that single-port PSH repair using preshaped, elastic 3-dimensional devices and additional flat mesh repair of the abdominal wall is feasible, safe, and beneficial, relating to optimal coverage of unstable stoma edges with wide overlap to all sides and simultaneous augmentation of the midline in the IPOM technique. The stoma relocation enables prolapse treatment and prevention. The features of a modular and rotatable multichannel port system offer benefits in clear dissection ongoing from a single port. Long-term follow-up data on an adequate number of patients are awaited to examine efficacy. PMID:25392655

Single-port video-assisted thoracoscopic surgery for lung cancer  

PubMed Central

In 2004, novel results using pulmonary wedge resection executed through single-port video-assisted thoracoscopic surgery (VATS) was first described. Since that time, single-port VATS has been advocated for the treatment of a spectrum of thoracic diseases, especially lung cancer. Lung cancer remains one of the top three cancer-related deaths in Taiwan, and surgical resection remains the “gold standard” for early-stage lung cancer. Anatomical resections (including pneumonectomy, lobectomy, and segmentectomy) remain the primary types of lung cancer surgery, regardless of whether conventional open thoracotomy, or 4/3/2-ports VATS are used. In the past three years, several pioneers have reported their early experiences with single-port VATS lobectomy, segmentectomy, and pneumonectomy for lung cancer. Our goal was to appraise their findings and review the role of single-port VATS in the treatment of lung cancer. In addition, the current concept of mini-invasive surgery involves not only smaller resections (requiring only a few incisions), but also sub-lobar resection as segmentectomy. Therefore, our review will also address these issues. PMID:24455171

Ventriculoperitoneal shunt and the need to remove a gallbladder: Time to definitely overcome the feeling that laparoscopic surgery is contraindicated  

PubMed Central

Since Baskin et al. reported the first documented case of failure of a laparoscopically-induced ventriculoperitoneal shunt (VP) in 1998, the cerebrospinal fluid shunt has been generally considered a relative contraindication to laparoscopy. Although the literature is limited there is a small body of evidence indicating that it is safe to perform laparoscopic surgery on these patients with routine anaesthetic monitoring. In this study we report the case of a laparoscopic cholecystectomy in the presence of a ventriculoperitoneal shunt. A review of the literature suggests that laparoscopic cholecystectomy can be safely performed in patients with a ventriculoperitoneal shunt. The only related contraindication should be if a catheter has recently been placed.

Demonstration of nasopharyngeal surgery with a single port operator controlled flexible endoscope system.  

PubMed

Introduction. Nasopharyngeal surgery is commonly performed with a rigid endoscope using a transnasal or transoral approach. Here, we demonstrate a flexible single port computer assisted endoscopic system enabling easy transoral access to the nasopharynx. Methods. Transoral nasopharyngeal surgery was performed in human cadavers (n=8) using the Flex(®) System (Medrobotics, Raynham, USA). Learning curves were evaluated based on the time necessary for reaching the Eustachian tube. Mock surgical procedures were performed with compatible flexible instruments. Results. Nasopharyngeal surgery is feasible with the Flex(®) System with a non-traumatic approach. The inbuilt HD digital camera enables high-quality visualization of the nasopharynx. The design of the flexible compatible tools adequately meets the requirements for surgical procedures in the nasopharynx. Conclusion. The single port operator controlled flexible endoscope system is a feasible way to approach the nasopharynx for surgical manipulation. Further clinical studies as well as development of supplemental tools are in progress. Head Neck, 2014. PMID:25351394

Urological applications of single-site laparoscopic surgery  

PubMed Central

Single-port, single-incision laparoscopy is part of the natural development of minimally invasive surgery. Refinement and modification of laparoscopic instrumentation has resulted in a substantial increase in the use of laparoendoscopic single-site surgery (LESS) in urology over the past 2 years. Since the initial report of single-port nephrectomy in 2007, the majority of laparoscopic procedures in urology have been described with a single-site approach. This includes surgery on the adrenal, ureter, bladder, prostate, and testis, for both benign and malignant conditions. In this review, we describe the current clinical applications and results of LESS in Urological Surgery. To date this evidence comes from small case series in centres of excellence, with good results. Further well-designed prospective trials are awaited to validate these findings. PMID:21197251

Risk Factors for Perioperative Anxiety in Laparoscopic Surgery  

PubMed Central

Background and Objectives: Our aim is to investigate the anxiety status of the patient before elective cholecystectomy and to analyze the relation between the level of anxiety for a given operation type (laparoscopic and open cholecystectomy) and the corresponding demographic and social data. Methods: A total of 333 patients undergoing cholecystectomy due to cholelithiasis were included in the study; 218 patients (66.1%) received laparoscopic cholecystectomy and 115 patients (33.9%) were treated with open cholecystectomy. The Beck Anxiety Inventory was given to all patients to be completed. We evaluated levels of anxiety in 3 groups as follows: 0 to 15, low to mild anxiety; 16 to 25, moderate anxiety; 26 to 63, severe anxiety. The following patient information remained confidential and was recorded: age and sex, associated disease, civil status, educational status, having open/laparoscopic cholecystectomy, previous knowledge of the operation, job status, economic status, health insurance, and having a child in need of care. Results: The following criteria were determined: the most determinant factors in differentiating between the score groups were having a low level of education, being of the female sex, being single, and having laparoscopic operation; the factors of being a homemaker and over the age of 25 years were determined to have significant effects. Conclusions: When analyzing the results that may appear during the intraoperative and postoperative period, understanding preoperative anxiety, analyzing the risk factors in depth, and taking the necessary precautions are all considerations that need to be the primary objectives of operators who are involved with laparoscopic, endoscopic, and robotic surgery.

Discussion about the necessity of intraoperative cholangiography restarted when laparoscopic cholecystectomy was established. The value of cholangiography was examined in a prospectively randomized study of one hundred patients. We could show that the routinely performed intraoperative cholangiography represents a careful, secure and sensitive method for the detection of common bile duct stones. As it is not very time consuming nor linked to high costs we believe it to be unrenouncible. It allows a detailed anatomic presentation and may be combined with ERCP for definitive treatment of bile duct stones. PMID:9206908

Getting started with robotics in general surgery with cholecystectomy: the Canadian experience  

PubMed Central

Background The value of robotics in general surgery may be for advanced minimally invasive procedures. Unlike other specialties, formal fellowship training opportunities for robotic general surgery are few. As a result, most surgeons currently develop robotic skills in practice. Our goal was to determine whether robotic cholecystectomy is a safe and effective bridge to advanced robotics in general surgery. Methods Before performing advanced robotic procedures, 2 surgeons completed the Intuitive Surgical da Vinci training course and agreed to work together on all procedures. Clinical surgery began with da Vinci cholecystectomy with a plan to begin advanced procedures after at least 10 cholecystectomies. We performed a retrospective review of our pilot series of robotic cholecystectomies and compared them with contemporaneous laparoscopic controls. The primary outcome was safety, and the secondary outcome was learning curve. Results There were 16 procedures in the robotics arm and 20 in the laparoscopic arm. Two complications (da Vinci port-site hernia, transient elevation of liver enzymes) occurred in the robotic arm, whereas only 1 laparoscopic patient (slow to awaken from anesthetic) experienced a complication. None was significant. The mean time required to perform robotic cholecystectomy was significantly longer than laparoscopic surgery (91 v. 41 min, p < 0.001). The mean time to clear the operating room was significantly longer for robotic procedures (14 v. 11 min, p = 0.015). We observed a trend showing longer mean anesthesia time for robotic procedures (23 v. 15 min). Regarding learning curve, the mean operative time needed for the first 3 robotic procedures was longer than for the last 3 (101 v. 80 min); however, this difference was not significant. Since this experience, the team has confidently gone on to perform robotic biliary, pancreatic, gastresophageal, intestinal and colorectal operations. Conclusion Robotic cholecystectomy can be performed reliably; however, owing to the significant increase in operating room resources, it cannot be justified for routine use. Our experience, however, demonstrates that robotic cholecystectomy is one means by which general surgeons may gain confidence in performing advanced robotic procedures. PMID:19865571

Two-Trocar Cholecystectomy by Strategic Laparoscopy for Improved Cosmesis (SLIC)  

PubMed Central

Background and Objectives: Until the advent of single-incision laparoscopic surgery, few advances were aimed at improving cosmesis with laparoscopic cholecystectomy. Criticisms of the single-incision laparoscopic surgery technique include a larger incision and increased incidence of wound-related complications. We present our initial experience with a novel technique aimed at performing strategic laparoscopy for improved cosmesis (SLIC) for cholecystectomy. Methods: Twenty-five patients with biliary symptoms were selected for SLIC cholecystectomy. Access to the abdomen was obtained with a 5-mm optical trocar in the left upper quadrant and a 5-mm trocar in the umbilicus. Retraction was performed by a transabdominal suture in the dome of the gallbladder and a needlescopic grasper. Age, American Society of Anesthesiologists score, body mass index, operative time, length of stay, pathology results, and short-term complications at follow-up were prospectively recorded. Results: The 25 female patients had a mean age of 34.3 years and mean body mass index of 24 kg/m2. American Society of Anesthesiologists scores ranged from 1 to 3. The mean operative time was 51.3 minutes. Pathology revealed chronic cholecystitis in all patients. All procedures were performed on an outpatient basis. The only complication was one ultrasonography-documented deep vein thrombosis. All 25 planned SLIC cholecystectomies were successfully completed. Conclusions: SLIC cholecystectomy is feasible and safe. This technique decreases the cumulative incision length, as well as the number of incisions, leading to very desirable cosmetic results in patients with a favorable body habitus and surgical history.

The laparoscopic learning curve.  

PubMed

To characterize the learning curve for laparoscopic cholecystectomy, we compared the first 47 cases (group A), which were performed by two senior attending surgeons who assisted each other when the procedure was introduced into clinical practice (1990-1991), with the first 46 cases (group R) performed by two surgical chief residents who were assisted by members of the teaching faculty in 1992-1993. The patient groups were comparable in terms of age, sex, and anesthetic class, but pathologically proven acute cholecystitis was more common in group R (33% vs. 9%; p < 0.005). To analyze operative procedures and outcomes, we compared operative time, frequency of successful operative cholangiography (attempted in all cases), frequency of conversion to open cholecystectomy, major complication rate, and days of postoperative stay for all patients and for those without complications. Of these parameters, only operative time for nonacute cases differed significantly between the groups (144 min for group A vs. 114 min for group R; p < 0.05). Complications in group A included one ductal injury and one case of postoperative pancreatitis; group R had one ductal injury and two cases of postoperative bleeding. We conclude that (a) the learning curve has similar structure for senior surgeons and resident trainees; and (b) the resident learning curve is not hazardous when teaching assistants are trained in the procedure, which has implications for safe instruction and proctoring of residents and staff.

Minireview on laparoscopic hepatobiliary and pancreatic surgery  

PubMed Central

The first laparoscopic cholecystectomy was performed in the mid-1980s. Since then, laparoscopic surgery has continued to gain prominence in numerous fields, and has, in some fields, replaced open surgery as the preferred operative technique. The role of laparoscopy in staging cancer is controversial, with regards to gallbladder carcinoma, pancreatic carcinoma, hepatocellular carcinoma and liver metastasis from colorectal carcinoma, laparoscopy in conjunction with intraoperative ultrasound has prevented nontherapeutic operations, and facilitated therapeutic operations. Laparoscopic cholecystectomy is the preferred option in the management of gallbladder disease. Meta-analyses comparing laparoscopic to open distal pancreatectomy show that laparoscopic pancreatectomy is safe and efficacious in the management of benign and malignant disease, and have better patient outcomes. A pancreaticoduodenectomy is a more complex operation and the laparoscopic technique is not feasible for this operation at this time. Robotic assisted pancreaticoduodenectomy has been tried with limited success at this time, but with continuing advancement in this field, this operation would eventually be feasible. Liver resection remains to be the best management for hepatocellular carcinoma, cholangiocarcinoma and colorectal liver metastases. Systematic reviews and meta-analyses have shown that laparoscopic liver resections result in patients with equal or less blood loss and shorter hospital stays, as compared to open surgery. With improving equipment and technique, and the incorporation of robotic surgery, minimally invasive liver resection operative times will improve and be more efficacious. With the incorporation of robotic surgery into hepatobiliary surgery, donor hepatectomies have also been completed with success. The management of benign and malignant disease with minimally invasive hepatobiliary and pancreatic surgery is safe and efficacious. PMID:24634709

Incidental cholecystojejunal fistula treated with successful laparoscopic management  

PubMed Central

Internal biliary fistula (IBF) is occurred spontaneously due to the biliary disease in most cases. Bilioenteric, biliobiliary, bronchobiliary, and vasculobiliary type of IBF have been reported in the literature. We herein describe our experience with an incidental cholecystojejunal fistula, a very rare type of bilioenteric fistula in laparoscopic cholecystectomy. A 61-year-old woman with several years' history of intermittent right upper abdominal pain was admitted to Soonchunhyang University Cheonan Hospital. Abdominal CT scan showed the pneumobilia in gallbladder with common bile duct dilatation. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy were done. On operative findings, there was a cholecystojejunal fistula. We performed laparoscopic cholecystectomy and fistulectomy with jejunal partial resection. To our knowledge, this is the first report on incidental cholecystojejunal fistula uncombined with any other disease and was treated with laparoscopic procedure. PMID:25368855

Single incision laparoscopic hepatectomy: Advances in laparoscopic liver surgery  

PubMed Central

BACKGROUND: Laparoscopic liver surgery is now an established practice in many institutions. It is a safe and feasible approach in experienced hands. Single incision laparoscopic surgery (SILS) has been performed for cholecystectomies, nephrectomies, splenectomies and obesity surgery. However, the use of SILS in liver surgery has been rarely reported. We report our initial experience in seven patients on single incision laparoscopic hepatectomy (SILH). PATIENTS AND METHODS: From October 2010 to September 2012, seven patients underwent single-incision laparoscopic liver surgery. The abdomen was approached through a 25 mm periumbilical incision. No supplemental ports were required. The liver was transected using a combination of LigaSure™ (Covidien-Valleylab. Boulder. USA), Harmonic Scalpel and Ligaclips (Ethicon Endo-Surgery, Inc.). RESULTS: Liver resection was successfully completed for the seven patients. The procedures consisted of two partial resections of segment three, two partial resections of segment five and three partial resections of segment six. The mean operative time was 98.3 min (range: 60-150 min) and the mean estimated blood loss was 57 ml (range: 25-150 ml). The postoperative courses were uneventful and the mean hospital stay was 5.1 days (range: 1-13 days). Pathology identified three benign and four malignant liver tumours with clear margins. CONCLUSION: SILH is a technically feasible and safe approach for wedge resections of the liver without oncological compromise and with favourable cosmetic results. This surgical technique requires relatively advanced laparoscopic skills. Further studies are needed to determine the potential advantages of this technique, apart from the better cosmetic result, compared to the conventional laparoscopic approach. PMID:24501503

Evaluation of Patient Satisfaction Using the EORTC IN-PATSAT32 Questionnaire and Surgical Outcome in Single-Port Surgery for Benign Adnexal Disease: Observational Comparison with Traditional Laparoscopy  

PubMed Central

Laparoscopic surgery has been demonstrated as a valid approach in almost all gynaecologic procedures including malignant diseases. Benefits of the minimally invasive approach over traditional open surgery have been well demonstrated in terms of minimal perioperative morbidity and reduced postoperative pain and hospital stay duration, with consequent quick postoperative recovery (Medeiros et al. (2009)). Single-port surgery resurfaced in gynaecology surgery in recent years and renewed interest among other surgeons and within the industry to develop this field (Podolsky et al. (2009)). Patient satisfaction is emerging as an increasingly important measure of quality which represents a complex entity that is dependent on patient demographics, comorbidities, disease, and, to a large extent, patient expectations (Tomlinson and Ko (2006)). It can be broadly thought to refer to all relevant experiences and processes associated with health care delivery (Jackson et al. (2001)). In this study we aim to compare single-port surgery (SPS) with conventional laparoscopy in terms of patient satisfaction using the EORTC IN-PATSAT32 questionnaire. We also evaluate the main surgical outcomes of both minimally invasive approaches. PMID:24371418

Stress analysis of single port (ISB) jumper connectors for 2-, 3-, and 4-in. sizes  

SciTech Connect

Jumper connectors are used in the Hanford site for remotely connecting jumper pipe lines in the radioactive zones. The jumper pipes are used for transporting radioactive fluids and hazardous chemicals. This report evaluates the adequacy and the integrity of the 2-, 3-, and 4-in. single-port integral seal block (ISB) jumper connector assemblies, as well as the three-way 2-in. configuration. The evaluation considers limiting forces from the piping to the nozzle. A stress evaluation of the jumper components (hook, hook pin, operating screw, nozzle and nozzle flange, and block) under operational (pressure, thermal, dead weight, and axial torquing of the jumper) and seismic loading is addressed in the report.

Single incision laparoscopic splenectomy, technical aspects and feasibility considerations  

PubMed Central

Minimally invasive techniques have been introduced to reduce morbidity related to standard laparoscopic procedures. One such approach is laparoendoscopic single-site surgery. The aim of the study was to present our initial clinical experience of using this technique for elective splenectomy. We carried out single access laparoscopic splenectomy (SALS) for an 8 cm cystic lesion of the spleen, involving the hilum, on a 38-year-old woman. The procedure was performed with a single-port device (4-channel) via a 2.5-cm umbilical incision. A flexible 5-mm optic and straight laparoscopic instruments were used. The operative time was 75 min. There was no blood loss. No complications were observed. The postoperative period was uneventful. Although substantial development of the instruments and skills is needed, this SALS technique appears to be feasible and safe. Nevertheless, further experience and observations are necessary.

Review. Laparoscopic appendicectomy: current status.  

PubMed Central

Laparoscopic appendicectomy (LA), has failed to gain unequivocal acceptance by the general surgical community as an alternative to open appendicectomy (OA). This is because the early postoperative recovery leading to quicker hospital discharge, which led to the worldwide acceptance of laparoscopic cholecystectomy, has not been universally seen with LA. Moreover, in the majority of the published series of LAs, there seems to be a trend towards an increased incidence of intra-abdominal abscesses. However, laparoscopy is superior to the 'watch and wait' policy where the diagnosis of appendicitis is questionable. Furthermore, since a large incision can be avoided by using the LA technique in obese patients, the incidence of postoperative morbidity can be reduced considerably. Nevertheless, before endorsing routine and widespread use of LA, it is essential that this technique is critically evaluated in well-designed, controlled, randomised trials, showing clearly the major benefits to the patient in terms of quicker hospital discharge, reduced postoperative pain, decreased wound infection and early return to full activities. Laparoscopic appendicectomy will never replace all open appendicectomies, but should become an alternative in certain groups of patients. PMID:9422862

Routine histopathology of gallbladder after elective cholecystectomy for gallstones: waste of resources or a justified act?  

PubMed Central

Background Selective approach for sending cholecystectomy specimens for histopathology results in missing discrete pathologies such as premalignant benign lesions such as porcelain gallbladder, carcinoma-in-situ, and early carcinomas. To avoid such blunders therefore, every cholecystectomy specimen should be routinely examined histologically. Unfortunately, the practice of discarding gallbladder specimen is standard in most tertiary care hospitals of Pakistan including the primary investigators’ own institution. This study was conducted to assess the feasibility or otherwise of performing histopathology in every specimen of gallbladder. Methods This cohort study included 220 patients with gallstones for cholecystectomy. All cases with known secondaries from gallbladder, local invasion from other viscera, traumatic rupture of gallbladder, gross malignancy of gallbladder found during surgery was excluded from the study. Laparoscopic cholecystectomy was performed in majority of cases except in those cases where anatomical distortion and dense adhesions prevented laparoscopy. All gallbladder specimens were sent for histopathology, irrespective of their gross appearance. Results Over a period of two years, 220 patients with symptomatic gallstones were admitted for cholecystectomy. Most of the patients were females (88%). Ninety two per cent patients presented with upper abdominal pain of varying duration. All specimens were sent for histopathology. Two hundred and three of the specimens showed evidence chronic cholecystitis, 7 acute cholecystitis with mucocele, 3 acute cholecystitis with empyema and one chronic cholecystitis associated with poly. Six gallbladders (2.8%) showed adenocarcinoma of varying differentiation along with cholelithiasis. Conclusion The histopathological spectrum of gallbladder is extremely variable. Incidental diagnosis of carcinoma gall bladder is not rare; if the protocol of routine histopathology of all gallbladder specimens is not followed, subclinical malignancies would fail to be identified with disastrous results. We strongly recommend routine histopathology of all cholecystectomy specimens. PMID:23834815

Quick Cooling and Filling Through a Single Port for Cryogenic Transfer Operations  

NASA Technical Reports Server (NTRS)

Improved technology for the efficient transfer of cryogens is needed for future on-orbit fueling and remote Lunar/Mars operations. The cooling and filling of a liquid nitrogen (LN2) test vessel through a single port were investigated in a series of experiments. A new 'in-space' transfer tube design concept was used to demonstrate the ability to quickly cool and load cryogens through a single feed-through connection. Three different fill tube configurations with three different diameters were tested. The tubes providing the quickest cooldown time and the quickest fill time for the test article tank were determined. The results demonstrated a clear trade-off between cooling time and filling time for the optimum tube design. This experimental study is intended to improve technology for future flight tank designs by reducing fill system size, complexity, heat leak rate, and operations time. These results may be applied to Space Shuttle Power Reactant Storage and Distribution (PRSD) System upgrades and other future applications. Further study and experimental analysis for optimization of the fill tube design are in progress.

Analysis and design of negative resistance oscillators using surface transverse wave-based single port resonators.  

PubMed

This practically oriented paper presents the fundamentals for analysis, optimization, and design of negative resistance oscillators (NRO) stabilized with surface transverse wave (STW)-based single-port resonators (SPR). Data on a variety of high-Q, low-loss SPR devices in the 900- to 2000-MHz range, suitable for NRO applications, are presented, and a simple method for SPR parameter extraction through Pi-circuit measurements is outlined. Negative resistance analysis, based on S-parameter data of the active device, is performed on a tuned-base, grounded collector transistor NRO, known for its good stability and tuning at microwave frequencies. By adding a SPR in the emitter network, the static transducer capacitance is absorbed by the circuit and is used to generate negative resistance only over the narrow bandwidth of the acoustic device, eliminating the risk of spurious oscillations. The analysis allows exact prediction of the oscillation frequency, tuning range, loaded Q, and excess gain. Simulation and experimental data on a 915-MHz fixed-frequency NRO and a wide tuning range, voltage-controlled STW oscillator, built and tested experimentally, are presented. Practical design aspects including the choice of transistor, negative feedback circuits, load coupling, and operation at the highest phase slope for minimum phase noise are discussed. PMID:12699155

Design and Coordination Kinematics of an Insertable Robotic Effectors Platform for Single-Port Access Surgery  

PubMed Central

Single port access surgery (SPAS) presents surgeons with added challenges that require new surgical tools and surgical assistance systems with unique capabilities. To address these challenges, we designed and constructed a new insertable robotic end-effectors platform (IREP) for SPAS. The IREP can be inserted through a Ø15 mm trocar into the abdomen and it uses 21 actuated joints for controlling two dexterous arms and a stereo-vision module. Each dexterous arm has a hybrid mechanical architecture comprised of a two-segment continuum robot, a parallelogram mechanism for improved dual-arm triangulation, and a distal wrist for improved dexterity during suturing. The IREP is unique because of the combination of continuum arms with active and passive segments with rigid parallel kinematics mechanisms. This paper presents the clinical motivation, design considerations, kinematics, statics, and mechanical design of the IREP. The kinematics of coordination between the parallelogram mechanisms and the continuum arms is presented using the pseudo-rigid-body model of the beam representing the passive segment of each snake arm. Kinematic and static simulations and preliminary experiment results are presented in support of our design choices. PMID:23963105

Uniportal video assisted thoracoscopic lobectomy: going directly from open surgery to a single port approach  

PubMed Central

Uniportal video-assisted thoracoscopy (VATS) has gaining a special place in the thoracic surgery scenario; nowadays even major pulmonary resections can be performed through this approach. We hereby review our initial experience with uniportal VAT lobectomy, performed passing directly from the open approach to a single port approach. We attempted 26 lobectomies through VATS with a single incision of about 5 cm and 22 of them were completed: eight left lower lobectomies, six right upper lobectomies, five left upper lobectomies and three right lower lobectomies. At pathological staging all but four patients were stage I; three patients were T2N1M0 and one had a micrometastasis in a lymph node of station 7 (T1N2M0—Stage IIIA) and they all underwent adjuvant chemotherapy. No perioperative mortality was observed. One patient had a myocardial infarction in the first postoperative day requiring placement of four stents and another one required thoracentesis after drainage removal. The mean time for drainage removal was 3 days and the length of hospitalization was 4.2±1.1. Pain as measured by the visual analogical scale (VAS) scale was graded as 4.9, 2.6 and 0.5 during the first postoperative day, at discharge and after 1 month respectively. PMID:25379203

Stump stone 6?years after cholecystectomy: A possibility  

PubMed Central

Calculi in the cystic duct remnant are one of the causes of postcholecystectomy syndrome. A 36-year-old woman presented thrice to the casualty department with right upper quadrant pain at an interval of 2?months every time. Ultrasound and CT scan of the abdomen was normal except for echoes in the gallbladder region may be clips. She was treated conservatively and discharged the first two times. The second time, the MR cholangiopancreatography was normal. She had undergone endoscopic retrograde cholangiopancreatography with sphincterotomy with stent in situ outside elsewhere before presenting to us for the third time, which was removed after 6-weeks. The third time, she was taken up for laparoscopic stump exploration, which revealed a stone, which was the cause of her pain. To conclude, stump stone can be a possibility of post cholecystectomy syndrome even after 6?years, and surgeons should be aware of it. PMID:23378549

Isolated right posterior bile duct injury following cholecystectomy: report of two cases.  

PubMed

Anatomic variations of the right biliary system are one of the most common risk factors for sectoral bile duct injury (BDI) during cholecystectomy. Isolated right posterior BDI may in particular be a challenge for both diagnosis and management. Herein we describe two cases of isolated right posterior sectoral BDI that took place during laparoscopic cholecystectomy. Despite effective external biliary drainage from the liver hilum in both cases, there was a persistent biliary leak observed which was not visible on endoscopic retrograde cholangiogram. Careful evaluation of images from both endoscopic and magnetic resonance cholangiograms revealed the diagnosis of an isolated right posterior sectoral BDI. These were treated with a delayed bisegmental (segments 6 and 7) liver resection and a Roux-en-Y hepaticojejunostomy respectively with good outcomes at 24 and 4 mo of follow-up. This paper discusses strategies for prevention of such injuries along with the diagnostic and therapeutic challenges it offers. PMID:24106416

Laparoscopic colectomy.  

PubMed Central

Fifty-one laparoscopic colectomies were attempted at two institutions. The clinical results and methods are presented. Seven cases (14%) were converted to facilitated procedures, and four cases (8%) were converted to "open." Cases of cancer, diverticulitis, endometriosis, regional enteritis, villous adenomas, and sessile polyps were operated. Right, transverse, left, low anterior, and abdominoperineal colectomies were performed. Colotomies and wedge resections were also performed. Laparoscopic suturing was required in five cases of incomplete anastomosis by circular stapler (18%). Suturing was required in all right, transverse colectomies and colotomies. Operative time averaged 2.3 hours. Hospitalization averaged 4.6 days. Four patients had complications (8%), and one 95-year-old died of pneumonia (2%). Laparoscopic colectomies can be performed safely, but require two-handed laparoscopic coordination, as well as suturing and knot-tying skills. Images FIG. 2. FIG. 3. PMID:1466626

The First Experiences of Robotic Single-Site Cholecystectomy in Asia: A Potential Way to Expand Minimally-Invasive Single-Site Surgery?  

PubMed Central

Purpose Herein, we firstly present the robotic single-site cholecystectomy (RSSC) as performed in Asia and evaluate whether it could overcome the limitations of conventional laparoscopic single-site cholecystectomy. Materials and Methods From October 2013 to November 2013, RSSC for benign gallbladder (GB) disease was firstly performed consecutively in five patients. We evaluated these early experiences of RSSC and compared factors including clinicopathologic factors and operative outcomes with our initial cases of single-fulcrum laparoscopic cholecystectomy (SFLC). Results Four female patients and one male patient underwent RSSC. Neither open conversion nor bile duct injury or bile spillage was noted during surgery. In comparisons with SFLC, patient-related factors in terms of age, sex, Body Mass Index, diagnosis, and American Society of Anesthesiologist score showed no significant differences between two groups. There were no significant differences in the operative outcomes regarding intraoperative blood loss, bile spillage during operation, postoperative pain scale values, postoperative complications, and hospital stay between the two groups (p<0.05). Actual dissection time (p=0.003) and total operation time (p=0.001) were significantly longer in RSSC than in SFLC. There were no drain insertion or open conversion cases in either group. Conclusion RSSC provides a comfortable environment and improved ergonomics to laparoscopic single-site cholecystectomy; however, this technique needs to be modified to allow for more effective intracorporeal movement. As experience and technical innovations continue, RSSC will soon be alternative procedure for well-selected benign GB disease. PMID:25510764

New trends in colorectal surgery: Single port and natural orifice techniques  

PubMed Central

Single-incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES) have rapidly gained pace worldwide, potentially replacing conventional laparoscopic surgery (CLS) as the preferred colorectal surgery technique. Currently available data mainly consist of retrospective series analyzed in four meta-analyses. Despite conflicting results and lack of an objective comparison, SILS appears to offer cosmetic advantages over CLS. However, due to conflicting results and marked heterogeneity, present data fail to show significant differences in terms of operative time, postoperative morbidity profiles, port-site complications rates, oncological appropriateness, duration of hospitalization or cost when comparing SILS with conventional laparoscopy for colorectal procedures. The application of “pure” NOTES in humans remains limited to case reports because of unresolved issues concerning the ideal access site, distant organ reach, spatial orientation and viscera closure. Alternatively, minilaparoscopy-assisted natural orifice surgery techniques are being developed. The transanal “down-to-up” total mesorectum excision has been derived for transanal endoscopic microsurgery (TEM) and represents the most encouraging NOTES-derived technique. Preliminary experiences demonstrate good oncological and functional short-term outcomes. Large-scale randomized controlled trials are now mandatory to confirm the long-term SILS results and validate transanal TEM for the application of NOTES in humans. PMID:25561780

Use of stapling devices for safe cholecystectomy in acute cholecystitis.  

PubMed

Abstract Many techniques are described for the ligation of a difficult cystic duct (CD). The aim of this study is to assess the effectiveness and safety of stapling of a difficult CD in acute cholecystitis using Endo-GIA. From January 2008 to June 2012, 1441 patients with cholelithiasis underwent laparoscopic cholecystectomy (LC) at the Department of General Surgery, Haydarpasa Numune Education and Research Hospital. Of these, 19 (0.62%) were identified as having a difficult CD and were ligated using an Endo-GIA stapler. All patients were successfully treated with a laparoscopic approach. The length of hospital stay was 3.4 days. There were umbilical wound infections in 4 patients (21%). The length of follow-up ranged from 1.0 to 50.4 months. In conclusion, Endo-GIA is a safe and easy treatment method for patients with a dilated and difficult CD. The cystic artery should be isolated and ligated if possible before firing the Endo-GIA stapler. If isolation and stapling are not possible, fibrin sealant can be applied to avoid bleeding. The vascular Endo-GIA can be applied in a large CD, but for acute cholecystitis with an edematous CD, the Endo-GIA roticulator 4.8 or 3.5 stapler is preferred. PMID:25216423

Laparoscopic Colorectal Surgery: An Update (with Special Reference to Indian Scenario)  

PubMed Central

Laparoscopic cholecystectomy, being already declared as gold standard technique, laparoscopic surgery has advanced far and wide, touching almost every corner of the abdomen. This advancement has gradually expanded to colorectal surgery which is done for malignant diseases as well. However, laparoscopic colorectal surgery has not been accepted as quickly as was laparoscopic cholecystectomy. This is because of its steep learning curve, concerns with oncological outcomes, lack of randomized control trials (RCTs) and initial reports on high port site recurrences which occurred after curative resections. But all these initial concerns have been overcome by doing a series of RCTs globally, in the past decade, that revealed that laparoscopic colorectal surgery for malignant disease offered short term benefits without compromising on oncological principles of radicality of resection, tumour resection margins and completeness of lymph node harvesting as compared to those of open surgery. Favourable post-operative results with respect to less blood loss, less pain, lesser surgical site infections, lesser requirement of analgesics, early return of bowel function and shorter hospital stay in patients who underwent laparoscopic colorectal resections were obtained in studies done on individual series, including those done in India and more recently, in large trials. An update on recent studies done on laparoscopic colorectal surgery by reviewing many RCTs and individual series, including our experiences, was made, to support the advantages of this procedure which were obtained when it was carried out by skilled hands.

Laparoscopic Resection for Rectal Cancer: What Is the Evidence?  

PubMed Central

Laparoscopic colectomy for colon cancer is a well-established procedure supported by several well-conducted large-scale randomised controlled trials. Patients could now be conferred the benefits of the minimally invasive approach while retaining comparable oncologic outcomes to the open approach. However, the benefits of laparoscopic proctectomy for rectal cancer remained controversial. While the laparoscopic approach is more technically demanding, results from randomised controlled trials regarding long term oncologic outcomes are only beginning to be reported. The impacts of bladder and sexual functions following proctectomy are considerable and are important contributing factors to the patients' quality of life in the long-term. These issues present a delicate dilemma to the surgeon in his choice of operative approach in tackling rectal cancer. This is compounded further by the rapid proliferation of various laparoscopic techniques including the hand assisted, robotic assisted, and single port laparoscopy. This review article aims to draw on the significant studies which have been conducted to highlight the short- and long-term outcomes and evidence for laparoscopic resection for rectal cancer.

Laparoscopic ultrasound for the diagnosis of choledocholithiasis: quick, safe, and effective.  

PubMed

Visualization of the common bile duct during laparoscopic cholecystectomy is frequently required to confirm or exclude choledocholithiasis. Although on-table cholangiogram (OTC) is the traditional imaging technique, laparoscopic ultrasound (LUS) is increasingly deployed for this purpose. We are reporting a 31-month experience with an LUS, starting from the initial set up of the equipment. We retrospectively studied 70 patients who underwent LUS during their laparoscopic cholecystectomy operation over a period of 31 months. Data about preoperative investigation, intraoperative findings, and postoperative outcome were retrospectively collected and analyzed. LUS was found to be quick, safe, and effective in the intraoperative diagnosis of the common bile duct stones. It does not add significantly to the operative time and is inherently safer than intraoperative cholangiogram owing to the fact that it does not involve ionizing radiation. It is also more convenient, as there is no need to wear protective lead to avoid the side effects of ionizing radiation. PMID:24710230

Laparoscopic surgery: A pioneer's point of view.  

PubMed

For a surgeon who performed some of the first laparoscopic cholecystectomies, laparoscopic surgery is undoubtedly the main revolution in the last decade of this century. It is impossible not to be fascinated by the extraordinary changes introduced in our profession in less than 10 years. However, looking back in history, one realizes that laparoscopy is but one of those leaps forward that have always punctuated the evolution of our profession. Since the last century we have witnessed the advent of painless surgery, infectionless surgery, reconstructive surgery, microsurgery, surgery under extracorporeal circulation, organ replacement, and so on. We are in the time of scarless surgery, with no lengthy postoperative handicap. Maybe tomorrow will see surgery performed by remote-controlled robots and surgery at the molecule level. The laparoscopic revolution is particularly important because for the first time surgery no longer involves any physical contact between the surgeon's hand and the patient. Let us hope that this will not lead to total absence of a human relationship in the surgical operation. To avoid this possibility we must remain resolutely involved in the development of laparoscopic surgery; we must keep our minds open to the future advances of science and technology and integrate them in our operative procedures.

[Laparoscopic splenectomy].  

PubMed

From 1995 to 1998, 14 patients have been treated with laparoscopic splenectomy. Seven patients had immune thrombocytopenic purpura (ITP), six hereditary spherocytosis and one chronic myelomonocytic leukaemia with trombocytopenia. 12 of the patients had normal or nearly normal sized spleen. Median duration of surgery was 156 minutes and the median postoperative hospital stay four days. All operations were completed laparoscopically. Three patients had postoperative fever without any sign of infection, one developed urinary retention and one was readmitted with pneumonia. The patient with chronic myelomonocytic leukaemia died 15 days postoperatively from an intracerebral bleeding. Two patients suffer from relapse of trombocytopenia, one is treated with steroids. Laparoscopic splenectomy can be performed safely in patients with normal sized spleen with all the advantages of minimal access surgery. However, problems related to identification of accessory spleens and splenectomy in patients with splenomegali, should be further evaluated. PMID:10327847

Laparoscopic Hysterectomy  

PubMed

Retrospective analysis of 200 laparoscopic hysterectomies performed from June 1991 to July 31, 1995, showed the main indications to be symptomatic uterine fibroids, advanced endometriosis, chronic pelvic inflammatory disease, and endometrial hyperplasia with atypia. Some women had more than one indication, and pathology reports contained more than one diagnosis. Three cases were converted to abdominal procedures. Operating room time was under 2 hours in general, and blood loss was around 120 ml. Most of the initial cases were performed with endostapling. This technique was changed in favor of bipolar and unipolar coagulation and suturing. Laparoscopic hysterectomy is a safe, superior technique that should be an integral part of gynecologic practice.

Laparoscopic oophorectomy.  

PubMed

Laparoscopic oophorectomy is one of the most controversial and challenging areas of endoscopic surgery. Judicious preoperative evaluation along with careful patient selection can reduce the risk of operating on an unsuspected ovarian malignancy. Appropriate patient consent and planning should be obtained before the procedure, in case an ovarian neoplasia should be encountered. Although endoscopic pelvic biopsy, treatment and staging has been reported recently, the standard of care still appears to be by a laparoscopy. The removal of benign cystic teratomas of all sizes can be handled laparoscopically with the assistance of a retrieval bag or pouch. Reports of endoscopic treatment of ovarian remnant syndrome, androgen insensitivity syndrome, and even prophylactic oophorectomy are appearing in the literature. They have major benefits to patients including reduced cost, decreased hospitalization and time away from work, and with similar or lower complication rates compared with other modes of treatment. Pelviscopy or operative laparoscopy is gaining in popularity and acceptance as our experience and training improves. PMID:7578970

Integrated image monitoring system using head-mounted display for gasless single-port clampless partial nephrectomy.  

PubMed

A novel head-mounted display (HMD) offers a higher quality of endoscopic imagery in front of the eyes regardless of head position. We present an application of the HMD system as a personal integrated multi-image monitoring system in gasless single-port clampless partial nephrectomy (PN). Our HMD system displayed multiple forms of information as integrated, sharp, high-contrast images both seamlessly and synchronously using a four-split screen. The surgeon wearing an HMD display could continuously and simultaneously monitor the endoscopic, three-dimensional (3D) video and intraoperative ultrasound images. In addition, the operator can rotate the 3D video image using fingertip movements on the finger tracking system. All two clampless partial nephrectomies were safely completed within the operative time, blood loss was within usual limits and there were no complications. The integrated image HMD system might facilitate maneuverability and safety in minimally invasive clampless PN. PMID:25562006

Robotic assisted Roux-en-Y hepaticojejunostomy in a post-cholecystectomy type E2 bile duct injury  

PubMed Central

Roux-en-Y hepaticojejunostomy anastomosis is the treatment of choice for common hepatic duct injury type E2. It has been performed laparoscopically with the advancement of laparoscopic skill. Recently, a telemanipulative robotic surgical system was introduced, providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field. We present a case of 36-year-old female patient who had undergone elective cholecystectomy 2 mo ago for gall stones and had a common bile duct injury during surgery. As the stricture was old and complete it could not be tackled endoscopically. We did a laparoscopic assisted adhesiolysis followed by robotic Roux-en-Y hepaticojejunostomy. No intraoperative complications or technical problems were encountered. Postoperative period was uneventful and she was discharged on the 4th postoperative day. At follow-up, she is doing well without evidence of jaundice or cholangitis. This is the first reported case of robotic hepaticojejunostomy following common bile duct injury. The hybrid technique gives the patient benefit of laparoscopic adhesiolysis and robotic suturing. PMID:25684934

Cholecystectomy and colorectal cancer in China.  

PubMed

Colorectal cancer is a major public health problem in China: 79,800 new cases are estimated to occur each year, which ranks it among the five most common tumours in China. Although the association between cholecystectomy and colorectal cancer has been studied elsewhere, few studies have been conducted in the Chinese population, characterized by a lower fat intake, and low colorectal cancer incidence. We conducted this hospital-based case-control study to explore this association. The study included a total of 503 incident cases with pathologically diagnosed colorectal cancer in Drum Tower Hospital at Nanjing in China from 1965 to 1986, and 2188 healthy controls who had annual routine physical examinations at the same hospital. Diagnosis of cholelithiasis was confirmed by ultrasonography or X-ray cholecystography, and the information on cholecystectomy was obtained by checking medical charts for both cases and controls. The prevalence of cholelithiases was 5.8% for cases and 6.1% for controls (P > 0.05). Eight cases (1.6%) and 18 controls (0.8%) had a history of previous cholecystectomy. The period between cases' cholecystectomy and diagnosis of colorectal cancer ranged from 2.5 to 23 years, and the mean interval was 8.9 years. The crude odds ratio for patients having previous cholecystectomy is 1.95 (95% CI: 0.84-4.51) compared with controls. The odds ratio for female patients with previous cholecystectomy was 2.79 (95% CI: 1.03-7.59). When subsites were analysed, a significant association between right colon cancer and cholecystectomy was noted: the odds ratio was 6.2 (95% CI: 2.24-16.9), and that for females was even higher 8.61 (95% CI: 2.44-3.04) with statistical significance.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8130937

Laparoscopic applications of laser-activated tissue glues  

NASA Astrophysics Data System (ADS)

The rapid growth of laparoscopic cholecystectomy and other laparoscopic procedures has created the need for simple, secure techniques for laparoscopic closure without sutures. While laser tissue welding offers one solution to this problem, concerns about adequacy of weld strength and watertightness remain. Tissue solders are proteinaceous materials which are placed on coapted tissue edges of the tissue to be closed or sealed. Laser energy is then applied to fix the glue in place completing the closure. Closure of the choledochotomy following a laparoscopic common duct exploration is one potential application of this technique. Canine longitudinal choledochotomies 5 mm in length were sealed using several laser glues and using the 808 nm diode laser. Saline was then infused until rupture of the closure and peak bursting strength recorded. Fibrinogen glue provided moderately good adhesion but poor burst strength. Handling characteristics were variable. A viscosity adjusted fibrinogen preparation produced good adherence with mean weld strength 264 +/- 7 mm Hg. The clinical endpoint for welding was a whitening and drying of the tissue. New laser solders can provide a watertight choledochotomy closure of adequate immediate strength. This would allow reliable, technically feasible common bile duct exploration via a laparoscopic approach.

The authors report their experience of 6 cases of appendicectomy using a laparoscopic route of which 5 were performed under local anesthesia and 1 under general anesthesia. The results indicate that this new technique is easy to perform and as rapid and safe as the traditional operation. The possibility of using local anesthesia, the lack of complications when operating on obese patients, the lower incidence of wound infections and rapid postoperative mobilisation all argue in favour of this alternative approach to conventional open surgery.

Plasma scalpel SUPR-M was used in operative treatment of calculous cholecystitis. Two variants of cholecystectomy with plasma scalpel have been worked out in experiment. It was determined, that the influence of plasma spurt is innocuous for hepatic tissues, it helps to achieve complete demucosation of the mucous membrane of the gall bladder in atypical variants of cholecystectomy, prevents bleeding and bile leakage from the bladder bead in typical cholecytectomy. In clinics the operation procedures were carried out in 176 patients, in 20 of them cholecystectomy was performed atypically, leaving gall bladder wall, adjacent to hepatic surface, in place. In postoperative period were no complications connected with the use of plasma scalpel as well as there were no lethal outcomes. Long-term follow-up of the patients for 5 years showed favourable clinical effect. PMID:9499131

Mouret, Dubois, and Perissat: The Laparoscopic Breakthrough in Europe (1987-1988)  

PubMed Central

In the late 1980s, laparoscopy was essentially a gynecologist's tool. One of the French private surgeons, Phillipe Mouret of Lyon, shared his surgery practice with a gynecologist and thus had access to both laparoscopic equipment and to patients requiring laparoscopy. In March of 1987, Mouret carried out his first cholecystectomy by means of electronic laparoscopy. Although he never published anything about this experience, the news on his technique reached Francois Dubois of Paris. Although having no prior laparoscopic experience, Dubois acted immediately. He borrowed the instruments from gynecologists, performed his first animal experiments and, in April 1988, carried out the first laparoscopic cholecystectomy (LC) in Paris. Inspired by Dubois, Jacques Perissat of Bordeaux, introduced endoscopie cholecystectomy in his clinic and presented this technique at a SAGES meeting in Louisville in April 1989. Very soon, news of the French work in LC soon swept beyond the country's borders. Dubois and Perissat spoke enthusiastically about their work at the meetings and were largely responsible for establishing what is today called the French technique. PMID:10444020

Management of acute cholecystitis in critically ill patients: contemporary role for cholecystostomy and subsequent cholecystectomy.  

PubMed

The diagnosis of acute cholecystitis in critically ill patients carries a high mortality rate. Although decompression and drainage of the gallbladder through a cholecystostomy tube may be used as a temporary treatment of acute cholecystitis in this population, there is still some debate about the management of the tube and the subsequent need for a cholecystectomy. This series evaluates the clinical course and outcomes of critically ill patients who underwent the insertion of cholecystostomy tubes for the initial treatment of acute cholecystitis. This is a retrospective review of critically ill patients admitted to the hospital intensive care unit who were diagnosed with acute cholecystitis and underwent a cholecystostomy tube as a temporary treatment for the disease. Patients were identified through the Greenville Hospital System electronic medical records coding database. Medical records were reviewed for demographic data, diagnoses, imaging, complications, and outcomes. From January 2002 through June 2008, 50 patients were identified for the study. The mean age was 72 +/- 11 years, and the majority (66%) were men. The following comorbidities were found: severe cardiovascular disease (40 patients), respiratory failure (30 patients), and multisystem organ dysfunction (30 patients). The mean intensive care unit length of stay (LOS) was 16 +/- 9 days, and the mean hospital LOS was 28 +/- 27 days. At 30 days, the morbidity associated with the cholecystostomy tube itself was 4 per cent, but overall in-hospital morbidity and mortality rates were 62 and 50 per cent, respectively. Of the 25 patients who survived longer than 30 days, 12 retained their cholecystostomy tubes until they underwent cholecystectomy (four open, seven laparoscopic). All of the remaining 13 patients had their cholecystostomy tubes removed, and eight developed recurrent cholecystitis. Of these patients with recurrent of cholecystitis, five had cholecystectomy or repeat cholecystostomy, but the remaining three patients died. Although this is a small patient population, these data suggest that, in critically ill patients, cholecystostomy tubes should remain in place until the patient is deemed medically suitable to undergo cholecystectomy. Removal of the cholecystostomy tube without subsequent cholecystectomy is associated with a high incidence of recurrent cholecystitis and devastating consequences. PMID:20698375

Incidence of Port-Site Incisional Hernia After Single-Incision Laparoscopic Surgery  

PubMed Central

Background and Objectives: Single-incision laparoscopic surgery is gaining popularity among minimally invasive surgeons and is now being applied to a broad number of surgical procedures. Although this technique uses only 1 port, the diameter of the incision is larger than in standard laparoscopic surgery. The long-term incidence of port-site hernias after single-incision laparoscopic surgery has yet to be determined. Methods: All patients who underwent a single-incision laparoscopic surgical procedure from May 2008 through May 2009 were included in the study. Single-incision laparoscopic surgical operations were performed either by a multiport technique or with a 3-trocar single-incision laparoscopic surgery port. The patients were seen at 30 to 36 months' follow-up, at which time they were examined for any evidence of port-site incisional hernia. Patients found to have hernias on clinical examination underwent repairs with mesh. Results: A total of 211 patients met the criteria for inclusion in the study. The types of operations included were cholecystectomy, appendectomy, sleeve gastrectomy, gastric banding, Nissen fundoplication, colectomy, and gastrojejunostomy. We found a port-site hernia rate of 2.9% at 30 to 36 months' follow-up. Conclusion: Port-site incisional hernia after single-incision laparoscopic surgical procedures remains a major setback for patients. The true incidence remains largely unknown because most patients are asymptomatic and therefore do not seek surgical aid. PMID:24960483

Enhanced visualization of the bile duct via parallel white light and indocyanine green fluorescence laparoscopic imaging  

NASA Astrophysics Data System (ADS)

Despite best efforts, bile duct injury during laparoscopic cholecystectomy is a major potential complication. Precise detection method of extrahepatic bile duct during laparoscopic procedures would minimize the risk of injury. Towards this goal, we have developed a compact imaging instrumentation designed to enable simultaneous acquisition of conventional white color and NIR fluorescence endoscopic/laparoscopic imaging using ICG as contrast agent. The capabilities of this system, which offers optimized sensitivity and functionality, are demonstrated for the detection of the bile duct in an animal model. This design could also provide a low-cost real-time surgical navigation capability to enhance the efficacy of a variety of other image-guided minimally invasive procedures.

Low COST surgery setting for one-operational port laparoscopic hysterectomy surgery with ordinary laparoscopic instruments: preliminary results  

PubMed Central

Background Hysterectomy dates back to 120BC and is the second most commonly performed gynecological surgery in the world. Cosmetic demands and the necessity of rapid return to work have contributed to the minimally invasive laparoscopic approach for hysterectomy. The majority of reports describe the use of three or four incisions to perform the surgery (two or three for manipulation and one for optics). Methods This work describes our experience with using only two ports for 11 patients who underwent video-laparoscopic hysterectomy surgery. One port was used for the optical system, and the second was used for manipulation. Early and late surgery complications, as well as the time to return to work and daily activities, were assessed. Results The mean age of the patients was 41.4 years old (range 16 to 52 years) and the mean uterine weight was 133.54 g, ranging from 35 g and 291 g. The operative time ranged from 30 to 60 minutes (average 46.4 minutes) and the hospital stay ranged between 24 and 48 hrs. No intraoperative complications occurred, and no early or late postoperative complications were recorded. Patients reported minimal pain during the first 24–48 hrs in the hospital. Patients returned to their daily activities within seven days after surgery. Clinical care follow-up continued until the 40th postoperative day. Conclusion The laparoscopic hysterectomy technique with a single port for manipulation is a feasible procedure when the uterine weight is not greater than 400 mg with little postoperative pain. The patients had an early return-to-work and daily activities and a better cosmetic outcome. These preliminary data led us to make the one-operative port laparoscopic hysterectomy the procedure of choice for patients with a low uterine weight. PMID:24088385

Laparoscopic nephrectomy in children for benign conditions: indications and outcome  

PubMed Central

Aim: To analyze the indications and outcome of laparoscopic nephrectomy for benign non-functioning kidneys in children. Materials and Methods: The data of all patients operated over a 10 year period was retrospectively analyzed. Results: There were 56 children, aged 4 months to 12 years with a male: female ratio of 2.3:1. The most common presentation in boys and girls was urinary tract infection (UTI) (61.5% and 47.05% respectively). Incontinence due to ectopic ureter was a close second in girls (41.17%). The most common underlying conditions were vesico-ureteric reflux (42.85%) and multicystic dysplastic kidney (23.2%). There were 6 nephrectomies, 4 heminephroureterectomies and the remaining nephroureterectomies. All children tolerated the surgery well. One patient underwent a concomitant cholecystectomy. The post-operative problems encountered were UTI (1), urine retention (1), pyonephrosis in the opposite kidney and development of contra-lateral reflux (1). All others had resolution of pre-operative symptoms with good cosmesis. Conclusions: As per available literature, this appears to be the largest Indian series of pediatric laparoscopic nephrectomies for benign non-functioning kidneys. Laparoscopic approach gives excellent results provided pre-operative investigations rule out other causes for the symptoms with which the patient presents. Often it is not the kidney but the dilated dysplastic ureter which is the seat of stasis and infection or pain and therefore should be completely removed. PMID:24604980

From November 1988 to February 1990 157 patients with gallbladder stones haven been treated by a laparoscopic surgical procedure. They are 28 males and 129 females from 13 to 81 years old. 18 have had a cholecystostomy after intracorporeal lithotripsy (Lus Ultrasonic Olympus). They were placed on bue acids during 3 months. The average follow up time is 11 months. The mortality is zero and 2 mild complications occurred medically cured. 3 patients have a recurrent stone 6 months after surgery. 139 patients have had a cholecystectomy 89 after the same lithotripsy procedure seen above, 50 without prior lithotripsy. In 3 cases the laparoscopic procedure was abandoned, twice because of a sever bleeding, one for too compact surrounding adhesions. The mean follow up is 9 months. 123 were drained 1 day 16 had no drain. The mortality is zero. 2 patients without drainage developed a sub hepatic and douglas pouch abscess. They were cured by a lavage drainage laparoscopically made. 1 patient with drainages had a 7 days bile leak, which disappeared spontaneously. The 136 others have had a short stay in the hospital (2-4 days) a painless post operative time. They could go back to work and sport within 1 week. They have minimal scars and no danger of incisional herriae. The magnification of the optical system enables the dissection of the cystic duct and artery easier and safer than it is by mini laparotomy mostly in obese people. At the beginning of our experience only the patients with frequent biliary colics have been selected for the laparoscopic procedure. At that time 13 patients with subacute cholecystitis and 9 patients with stones in the commun bile duct have had a laparoscopic cholecystectomy associated with an endoscopic sphincterotomy in the last cases without complications.

New three-dimensional head-mounted display system, TMDU-S-3D system, for minimally invasive surgery application: procedures for gasless single-port radical nephrectomy.  

PubMed

We present an application of a new three-dimensional head-mounted display system that combines a high-definition three-dimensional organic electroluminescent head-mounted display with a high-definition three-dimensional endoscope to minimally invasive surgery, using gasless single-port radical nephrectomy procedures as a model. This system presents the surgeon with a higher quality of magnified three-dimensional imagery in front of the eyes regardless of head position, and simultaneously allows direct vision by moving the angle of sight downward. It is also significantly less expensive than the current robotic surgery system. While carrying out gasless single-port radical nephrectomy, the system provided the surgeon with excellent three-dimensional imagery of the operative field, direct vision of the outside and inside of the patient, and depth perception and tactile feedback through the devices. All four nephrectomies were safely completed within the operative time, blood loss was within usual limits and there were no complications. The display was light enough to comfortably be worn for a long operative time. Our experiences show that the three-dimensional head-mounted display system might facilitate maneuverability and safety in minimally invasive procedures, without prohibitive cost, and thus might mitigate the drawbacks of other three-dimensional vision systems. Because of the potential benefits that this system offers, it deserves further refinements of its role in various minimally invasive surgeries. PMID:22587397

It is to our knowledge the first time ever a mechanical experiment has been performed under laparoscopic conditions on the human, which enables determining corresponding constitutive model equations. As most important results, the feasibility of laparoscopic tissue aspiration has been demonstrated and, based on an ad hoc parameter for the tissue stiffness, the liver and the stomach gave significantly different responses. Furthermore, the determined constitutive behavior for one healthy human liver was in line with results obtained from tissue aspiration during open surgery. Eventually, laparoscopic tissue aspiration might qualify as minimally invasive testing method for tactile feedback systems. The presented results are preliminary and more research is required.

Laparoscopic splenectomy in patients with hereditary spherocytosis: report on 12 consecutive cases.  

PubMed

Hereditary spherocytosis is an inherited hemolytic anemia caused by a deficiency in erythrocyte membrane proteins. Removal of the spleen may reduce the intra-splenic hemolytic process of the disease and, therefore, may correct the anemia. Furthermore, it seems to decrease the levels of serum bilirubin, thus reducing the formation of gallbladder stones. Indications and timing of splenectomy, however, are still debated. Twelve patients with severe hereditary spherocytosis operated on with laparoscopic splenectomy were retrospectively reviewed. Median age at diagnosis was 13.8 years (range 8-25 years). Male to female ratio was 5/7. Indications for laparoscopic removal of the spleen included anemia unresponsive to iron supplementation in eight patients (66.6 %) with increase need for red cells transfusions, and jaundice with symptoms related to cholelitiasis in four patients (33.3 %). Laparoscopic splenectomy was associated in four cases to laparoscopic cholecystectomy. Mean operative time was 50 min (range 40-75 min) with no conversion to open surgery. Mean hospital stay ranged from 3 to 7 days. In a 16-month follow-up, no complications were recorded and a persistent correction of anemia was observed. With the advent of laparoscopic surgery, splenectomy has been performed by this mini-invasive approach in referral centers. Laparoscopic splenectomy is an effective technique, when performed in patients with hereditary spherocytosis. Low complication rate and persistent correction of the hematologic disorders can be expected after the laparoscopic splenectomy, provided that a proper technique is performed and an experienced surgical team is available.

Cholecystectomy and NAFLD: does gallbladder removal have metabolic consequences?  

PubMed

Pathogenesis of nonalcoholic fatty liver (NAFLD) disease and gallbladder (GB) disease secondary to cholesterol gallstones is complex, yet both conditions share similar associated risk factors, most of them related to the metabolic syndrome. Cholecystectomy, the best treatment for GB disease, is one of the most performed abdominal surgeries worldwide. In this issue of the American Journal of Gastroenterology, Ruhl and Everhart, using data from the Third United States National Health and Nutrition Examination Survey (1988-1994), show that NAFLD is associated with cholecystectomy (odds ratio (OR)=2.4; 1.8-3.3), but not with gallstones (OR=1.1; 0.84-1.4). This finding suggests that cholecystectomy may itself represent a risk factor for NAFLD, which is in line with the recently undisclosed role of the GB and bile acids in systemic metabolic regulation. Thus, cholecystectomy may not be innocuous and may have a major impact on public health by contributing to NAFLD development. PMID:23735917

Laparoscopic surgery and muscle relaxants: is deep block helpful?  

PubMed

It has been hypothesized that providing deep neuromuscular block (a posttetanic count of 1 or more, but a train-of-four [TOF] count of zero) when compared with moderate block (TOF counts of 1-3) for laparoscopic surgery would allow for the use of lower inflation pressures while optimizing surgical space and enhancing patient safety. We conducted a literature search on 6 different medical databases using 3 search strategies in each database in an attempt to find data substantiating this proposition. In addition, we studied the reference lists of the articles retrieved in the search and of other relevant articles known to the authors. There is some evidence that maintaining low inflation pressures during intra-abdominal laparoscopic surgery may reduce postoperative pain. Unfortunately most of the studies that come to these conclusions give few if any details as to the anesthetic protocol or the management of neuromuscular block. Performing laparoscopic surgery under low versus standard pressure pneumoperitoneum is associated with no difference in outcome with respect to surgical morbidity, conversion to open cholecystectomy, hemodynamic effects, length of hospital stay, or patient satisfaction. There is a limit to what deep neuromuscular block can achieve. Attempts to perform laparoscopic cholecystectomy at an inflation pressure of 8 mm Hg are associated with a 40% failure rate even at posttetanic counts of 1 or less. Well-designed studies that ask the question "is deep block superior to moderate block vis-à-vis surgical operating conditions" are essentially nonexistent. Without exception, all the peer-reviewed studies we uncovered which state that they investigated this issue have such serious flaws in their protocols that the authors' conclusions are suspect. However, there is evidence that abdominal compliance was not increased by a significant amount when deep block was established when compared with moderate neuromuscular block. Maintenance of deep block for the duration of the pneumoperitoneum presents a problem for clinicians who do not have access to sugammadex. Reversal of block with neostigmine at a time when no response to TOF stimulation can be elicited is slow and incomplete and increases the potential for postoperative residual neuromuscular block. The obligatory addition of sugammadex to any anesthetic protocol based on the continuous maintenance of deep block is not without associated caveats. First, monitoring of neuromuscular function is still essential and second, antagonism of deep block necessitates doses of sugammadex of ?4.0 mg/kg. Thus, maintenance of deep block has substantial economic repercussions. There are little objective data to support the proposition that deep neuromuscular block (when compared with less intense block; TOF counts of 1-3) contributes to better patient outcome or improves surgical operating conditions.

[Nephrectomy - pro laparoscopic].  

PubMed

Laparoscopic radical nephrectomy (LRN) is considered as a standard of care for T2 renal masses and T1 tumors not treatable by nephron-sparing surgery. It can be performed transperitoneally, retroperitoneoscopic or hand-assisted. However, the morbidity after laparoscopic nephrectomy has been shown to be lower than the open procedure and patients seem to benefit from early mobilization, less pain medication, shorter hospital stays and an earlier return to normal daily activities. Furthermore, the extent of perioperative activation of the systemic stress response appears to be less during laparoscopic procedures. This has been shown to have evidently beneficial clinical impact on patient's recovery; however, its importance for the oncologic prognosis is somewhat unclear. In addition, the progression-free and overall tumor-specific survival rates for laparoscopic nephrectomy are equivalent to those for open surgery. The experiences with robot-assistance for laparoscopic nephrectomy reported so far show no significant advantages over traditional laparoscopic nephrectomy. However, the problem of high costs of acquisition and operation of robots still remains unsolved. For the future, prospective studies are needed in order to compare the functional and oncological outcomes and cost-effectiveness of different methods of radical nephrectomy. PMID:22526177

Laparoscopic treatment of a hepatic subcapsular abscess secondary to gallbladder perforation: case report.  

PubMed

We present a rare case of type II Niemeier gallbladder perforation(GBP) developed as a complication of acute calculous cholecystitis. A 76-year-old man was admitted to our surgical unit with the presumptive diagnosis of acute cholecystitis. CT scan revealed a subcapsular collection developed on the visceral surface of the right hepatic lobe. It was communicating through a thin hypodense band with the cystic duct, distal to an impacted stone. Through laparoscopy the collection was confirmed to be a subcapsular liver abscess secondary to GBP.The cholecystectomy and the abscess cavity treatment were completely handled via laparoscopic approach. The paper demonstrates that laparoscopic approach can be a safe and feasible method in order to treat both the cause and the complication in this situation. Early diagnosis and appropriate minimally invasive approach are the key to manage this rarity. PMID:24524484

Laparoscopic surgery in endometriosis.  

PubMed

Endometriosis (the presence of endometrial glands and stroma outside of the uterine cavity) is a common gynecologic problem affecting 10% of women in the general population, 40% of women with infertility and 60% of women with chronic pelvic pain. Laparoscopy has revolutionized management of women with endometriosis. Diagnosis of endometriosis depends on visualization of endometriotic lesions and histologic confirmation. Endometriotic implants have a multitude of appearances: powder burns, red, blue-black, yellow, white, clear vesicular and peritoneal windows. Diagnostic laparoscopy is often combined with operative procedures to treat manifestations and symptoms of endometriosis. This often includes removal or laser vaporization of endometriotic implants, lysis of adhesions, restoration of normal anatomy and removal or fulguration of ovarian endometriomas (conservative surgery). Severe incapacitating endometriosis, recurrent endometriosis following conservative surgery and symptomatic endometriosis in women not desiring more children is often treated by laparoscopic unilateral or bilateral salpingo-oophorectomy or laparoscopically-assisted vaginal hysterectomy with bilateral salpingo-oophorectomy (radical surgery). Endometriosis affecting the appendix, ureters, bladder wall and rectosigmoid colon could be treated with laparoscopic appendectomy, excision of endometriotic implants or laparoscopic colectomy and anastomosis, respectively. Hydrodis-section and use of CO2 super pulsed laser aid in removal of adherent endometriotic implants without damage to normal underlying structures. Robotic-assisted laparoscopic surgery promises to provide advantages in the management of women with severe endometriosis secondary to 3-dimensional visualization, decreasing surgeon's fatigue and hand tremors and improving surgical precision.

Laparoscopic surgery in weightlessness  

NASA Technical Reports Server (NTRS)

BACKGROUND: Performing a surgical procedure in weightlessness has been shown not to be any more difficult than in a 1g environment if the requirements for the restraint of the patient, operator, and surgical hardware are observed. The feasibility of performing a laparoscopic surgical procedure in weightlessness, however, has been questionable. Concerns have included the impaired visualization from the lack of gravitational retraction of the bowel and from floating debris such as blood. METHODS: In this project, laparoscopic surgery was performed on a porcine animal model in the weightlessness of parabolic flight. RESULTS: Visualization was unaffected due to the tethering of the bowel by the elastic mesentery and the strong tendency for debris and blood to adhere to the abdominal wall due to surface tension forces. CONCLUSIONS: There are advantages to performing a laparoscopic instead of an open surgical procedure in a weightless environment. These will become important as the laparoscopic support hardware is miniaturized from its present form, as laparoscopic technology becomes more advanced, and as more surgically capable crew medical officers are present in future long-duration space-exploration missions.

Laparoscopic donor nephrectomy.  

PubMed

Living donor nephrectomy has been developed and promoted as a method to address the shortfall in kidneys available for transplantation. The classical method to procure a kidney from a living donor is the open donor nephrectomy performed through a flank lumbotomy incision. However, this classical method has negative short- and long-term side effects for the donor. These disincentives are a drawback for possible donors to donate a kidney. Therefore, transplant surgeons were stimulated to develop new and less invasive techniques. In this review several new open and laparoscopic techniques are described. Compared with open donor nephrectomy, laparoscopic donor nephrectomy has shown superior results in terms of postoperative pain, cosmetics, convalescence, and return to normal daily activities. No significant differences exist between the two approaches in terms of complication rates, cost-effectiveness and graft function. Nowadays, laparoscopic donor nephrectomy has become the preferred method for procuring kidney grafts of living donors in many centres. PMID:20508268

[Relaparoscopy as an alternative to laparotomy for laparoscopic complications].  

PubMed

In the field of visceral surgery, complications requiring reintervention following laparoscopy are currently most likely to be approached with conventional laparotomy. However, relaparoscopy has the theoretical advantage of maintaining the reduced morbidity allowed by the first procedure. Essential to the success of relaparoscopy is a clear understanding of the various specific complications. Should the surgeon decide on relaparoscopy, then prompt action is of central importance. Following laparoscopic cholecystectomy, it is fundamentally technically possible through renewed laparoscopy to treat not only subhepatic abscesses but also smaller lesions of the bile duct, for example from the gall bladder fossa. Revision of complications following fundoplication is technically very demanding and should be performed only by those most experienced in the techniques of laparoscopy. In contrast to interventional drainage, relaparoscopy of abscesses following laparoscopic appendectomy has the theoretical advantage of allowing recognition and treatment of the causes, for example in the case of appendicular stump insufficiency. Relapses very shortly after endoscopic surgery of inguinal herniae result from erroneous technique and may be corrected endoscopically in most cases. Complications following colon surgery have so far been dealt with using open surgery for technical reasons and also for patient safety. Given the uncertainty in the literature, patient safety must be paramount, when deciding on which technique is best to employ, particularly in cases of haemorrhage. PMID:17036247

Intraoperative ultrasound as an educational guide for laparoscopic biliary surgery  

PubMed Central

AIM: To analyze the efficacy of routine intraoperative ultrasound (IOUS) as a guide for understanding biliary tract anatomy, to avoid bile duct injury (BDI) after laparoscopic cholecystectomy (LC), as well as any burden during the learning period. METHODS: A retrospective analysis was performed using 644 consecutive patients who underwent LC from 1991 to 2006. An educational program with the use of IOUS as an operative guide has been used in 276 cases since 1998. RESULTS: IOUS was highly feasible even in patients with high-grade cholecystitis. No BDI was observed after the introduction of the educational program, despite 72% of operations being performed by inexperienced surgeons. Incidences of other morbidity, mortality, and late complications were comparable before and after the introduction of routine IOUS. However, the operation time was significantly extended after the educational program began (P < 0.001), and the grade of laparoscopic cholecystitis (P = 0.002), use of IOUS (P = 0.01), and the experience of the surgeons (P = 0.05) were significant factors for extending the length of operation. CONCLUSION: IOUS during LC was found to be a highly feasible modality, which provided accurate, real-time information about the biliary structures. The educational program using IOUS is expected to minimize the incidence of BDI following LC, especially when performed by less-skilled surgeons. PMID:18416464

STATIN USE AND THE RISK OF CHOLECYSTECTOMY IN WOMEN  

PubMed Central

Background Statins can reduce biliary cholesterol secretion independently of their ability to inhibit cholesterol synthesis. They also prevent formation of gallstones in animal studies, although the effect of statins on human gallstone disease has been controversial. Methods We examined the relationship between use of statins and the risk of cholecystectomy in a cohort of U.S. women. As part of the prospective Nurses’ Health Study, participants biennially reported history of gallstone disease and whether they had undergone cholecystectomy. Women also reported lifetime use of statins retrospectively in 2000. We conducted a retrospective analysis of statin using data collected in 2000, to define use from 1994 forward, and a prospective analysis for general lipid-lowering drugs from 1994 to 2004. Results In the statin analysis we ascertained 2,479 cases of cholecystectomy during 305,197 person-years of follow-up. The multivariate relative risk for current statin users, compared with nonusers, was 0.82 (95% confidence interval, 0.70 to 0.96). In the analysis of general cholesterol-lowering drugs, we ascertained 3,420 cases of cholecystectomy during 511,411 person-years of follow-up. Compared with nonusers, the multivariate relative risk for current users of general cholesterol-lowering drugs, mostly statins in this cohort, was 0.88 (95% confidence interval, 0.79 to 0.98). Conclusions Statin use appears to reduce the risk of cholecystectomy in women. PMID:19208351

Single-incision versus conventional laparoscopic appendectomy in 688 patients: a retrospective comparative analysis  

PubMed Central

Background Laparoscopic surgery has become the standard for treating appendicitis. The cosmetic benefits of using single-incision laparoscopy are well known, but its duration, complications and time to recovery have not been well documented. We compared 2 laparoscopic approaches for treating appendicitis and evaluated postoperative pain, complications and time to full recovery. Methods We retrospectively reviewed the cases of consecutive patients with appendicitis and compared those who underwent conventional laparoscopic appendectomy (CLA) performed using 3 incisions and those who underwent single-incision laparoscopic appendectomy (SILA). During SILA, the single port was prepared to increase visibility of the operative site. Results Our analysis included 688 consecutive patients: 618 who underwent CLA and 70 who underwent SILA. Postsurgical complications occurred more frequently in the CLA than the SILA group (18.1% v. 7.1%, p = 0.018). Patients who underwent SILA returned to oral feeding sooner than those who underwent CLA (median 12 h v. 22 h, p < 0.001). These between-group differences remained significant after controlling for other factors. Direct comparison of only nonperforated cases, which was determined by pathological examination, revealed that SILA was significantly longer than CLA (60 min v. 50 min, p < 0.001). Patients who underwent SILA had longer in-hospital stays than those who underwent CLA (72 v. 55 h, p < 0.001); however, they had significantly fewer complications (3.0% v. 14.4%, p = 0.006). Conclusion In addition to its cosmetic advantages, SILA led to rapid recovery and no increase in postsurgical pain or complications. PMID:24869622

Metastatic renal cell carcinoma--an unexpected finding after laparoscopic cholecystectomy.  

PubMed

Tumours metastasising to the gallbladder from other sites are rare; we aim to present a case of this unusual site of metastasis and give an overview of the current literature surrounding it. A case of renal cell carcinoma (RCC) with gallbladder metastasis is presented, along with a brief summary of the literature. A 55-year-old female presented with symptoms due to a large right RCC. Staging investigations were negative for metastasis and she underwent curative resection. She presented 8 years later with cholecystitis, and histological examination of the gallbladder specimen identified metastatic renal cell carcinoma which was not identified on preoperative imaging. RCC metastases to the gallbladder are unusual, but probably more common than recognised. They're frequently not identified preoperatively, and prognosis is similar to isolated metastases to other organs. PMID:25228426

From the lumen to the laparoscope.  

PubMed

Throughout the ages, the issues that have defined the management of disease processes have been particularly exemplified in the gastrointestinal tract. The use of gas lamps and candles with reflectors by Bozzini, Segalas, Cruise, and Fisher (19th century) allowed for some ingress into both the upper and lower gastrointestinal tract. Von Mikulicz, Leiter, Nitze, Kelling, and Jacobaeus contributed to the development of rigid instruments that could be used endoscopically or laparoscopically. Endoscopic efforts were amplified and extended by Rosenheim, Sternberg, Wolf, and, finally, Schindler, who not only introduced novel lens systems but also for the most part overcame the problems of flexibility and illumination. Bernheim, Ruddock, Veress, and Palmer made significant technical and clinical contributions to abdominal cavity exploration. The subsequent application of Hopkins and Kapany's work on optics, and the development by Hirschowitz and Curtiss of the flexible fiber optic endoscope, enabled the design of instruments that would allow the appropriate illumination and vision of both the farthest reaches of the bowel as well as the interior of the abdomen. Thus, the same endoscopic instruments coupled with a surgical interest in diagnostic laparotomy allowed for the evolution of minimally invasive surgery along a similar timescale. The cycle whereby diagnostic laparotomy in the early part of the century was supplanted by endoscopy and laparoscopy has now attained full circle whereby laparoscopy has evolved from a diagnostic procedure into one with major therapeutic applications and is perceived as the state-of-the-art technique for a wide variety of operations, including appendectomy, cholecystectomy, hernia repair, fundoplication, splenectomy, colectomy, and gastrointestinal anastomoses.

ICG-loaded microbubbles for multimodal billiary imaging in cholecystectomy  

NASA Astrophysics Data System (ADS)

A dual-mode imaging technique has been developed for intraoperative imaging of bile ducts and real-time identification of iatrogenic injuries in cholecystectomy. The technique is based on ultrasound (US) and fluorescence (FL) imaging of a dual-mode microbubble (MB) agent comprising a poly (lactic-co-glycolic acid) (PLGA) shell and a core of Indocyanine Green. During cholecystectomy, a clinical US probe is used to localize the bile duct structure after bolus injection of dual-mode MBs. As the surrounding adipose tissue is removed and the Calot's triangle is exposed, FL imaging is used to identify the MB distribution and to determine the potential bile duct injury. The contrast-enhanced bile duct imaging technique has been demonstrated in both a surgical simulation model and an ex vivo porcine tissue model under two surgical scenarios. The first scenario simulates the correct procedure where the cystic duct is clipped. The second scenario simulates the incorrect procedure where the common bile duct is clipped, leading to consequent bile duct injury. Benchtop experiments in both the phantom and the ex vivo models show that the dual-mode imaging technique is able to identify the potential bile duct injury during cholecystectomy. A phantom system has also been established for future device calibration and surgical training in image-guided cholecystectomy. Further in vivo animal validation tests are necessary before the technique can be implemented in a clinical setting.

Laparoscopic robotic total gastrectomy  

PubMed Central

Minimally invasive gastrectomy has become the standard of care in many centers in Asia but remains unpopular in Europe. The aim of this article is to present the technique of laparoscopic robot-assisted total gastrectomy. The presented case involved a 66-year-old female patient with an advanced gastric cancer on the lesser curvature of the stomach. The laparoscopic part of the procedure involved opening the lesser sac, mobilization of the greater curvature and transection of the duodenum. A robot was used for the D2 lymphadenectomy and creation of the anastomosis. In summary, we have found that during a total gastrectomy for advanced gastric cancer a successful oncological resection can be achieved using a minimally invasive approach. We have also found that by combining conventional laparoscopy with robotic assistance we could overcome the technical difficulties with regards to lymph node dissection and anastomosis.

Laparoscopic specimen retrieval bags.  

PubMed

Specimen retrieval bags have long been used in laparoscopic gynecologic surgery for contained removal of adnexal cysts and masses. More recently, the concerns regarding spread of malignant cells during mechanical morcellation of myoma have led to an additional use of specimen retrieval bags for contained "in-bag" morcellation. This review will discuss the indications for use retrieval bags in gynecologic endoscopy, and describe the different specimen bags available to date. PMID:25368466

Laparoscopic Radical Trachelectomy  

PubMed Central

Introduction: The standard treatment for patients with early-stage cervical cancer has been radical hysterectomy. However, for women interested in future fertility, radical trachelectomy is now considered a safe and feasible option. The use of minimally invasive surgical techniques to perform this procedure has recently been reported. Case Description: We report the first case of a laparoscopic radical trachelectomy performed in a developing country. The patient is a nulligravid, 30-y-old female with stage IB1 adenocarcinoma of the cervix who desired future fertility. She underwent a laparoscopic radical trachelectomy and bilateral pelvic lymph node dissection. The operative time was 340 min, and the estimated blood loss was 100mL. There were no intraoperative or postoperative complications. The final pathology showed no evidence of residual disease, and all pelvic lymph nodes were negative. At 20 mo of follow-up, the patient is having regular menses but has not yet attempted to become pregnant. There is no evidence of recurrence. Conclusion: Laparoscopic radical trachelectomy with pelvic lymphadenectomy in a young woman who desires future fertility may also be an alternative technique in the treatment of early cervical cancer in developing countries.

Adequacy of laparoscopic oophorectomy.  

PubMed

Ovarian remnant syndrome occurs infrequently after oophorectomy, yet when present it can contribute greatly to pelvic discomfort. The syndrome may be difficult to diagnose, identify surgically, and treat without intraoperative or postoperative complications developing. Recently, laparoscopic oophorectomy has been performed with increasing frequency. We assessed the outcome after laparoscopic removal of both ovaries or the sole remaining ovary in 27 premenopausal women. No intraoperative or postoperative complications were identified, and no patients have experienced symptoms consistent with ovarian remnant syndrome. All women had a marked rise in serum follicle-stimulating hormone (FSH) levels (81 to 72+/-5 mIU/ml), and luteinizing hormone (LH) levels (8+/-1 to 37+/-3 mIU/ml) after oophorectomy, and all but one had FSH levels 40 mIU/ml or above. Thirteen women had gonadotropin levels measured after 4 weeks of hormone replacement therapy; all had reductions in FSH levels, but 10 had elevations of their LH levels. These findings indicate that ovarian remnant syndrome occurs infrequently after laparoscopic oophorectomy. In addition, the data suggest a different, nonovarian regulation of gonadotropin secretion.

Laparoscopic inguinal hernia repair.  

PubMed

Between March 1991 and May 1994, 444 laparoscopic inguinal hernia repairs were undertaken in 375 patients: 386 transperitoneal and 58 extraperitoneal. During a follow-up period of 20.5 months (range 1-38) there have been three recurrences at 6, 7 and 12 months, all direct and all after transperitoneal repair. A total of 52 patients were treated as a day case (< 6 h), 317 patients spent less than 24 h in hospital and four patients were discharged on the second postoperative day. Operating time for transperitoneal hernia repair was 27 min (range 10-68) and extraperitoneal repair, 29 min (range 11-48). Short-term complications occurred in 18 patients: six haematomas, four seromas, one urinary retention and seven suffered persistent groin pain. Six patients have had neuralgia, three have had mesh removed and three further patients had individual clips removed from within the inguinal canal. There have been two adhesive small bowel obstructions. The first occurred 2 months after laparoscopic surgery and required laparotomy; the second occurred 2 years after surgery and had laparoscopic division of an adhesive band to a pelvic staple. There was one infected lymphocoele treated percutaneously. PMID:7741670

Totally laparoscopic gallbladder-preserving surgery: A minimally invasive and favorable approach for cholelithiasis  

PubMed Central

The aim of the present study was to investigate the effectiveness of laparoscopic gallbladder-preserving surgery (L-GPS) for cholelithiasis and the feasibility and value of totally laparoscopic GPS (TL-GPS). A total of 517 patients underwent L-GPS, including 365 cases of laparoscopy-assisted GPS (LA-GPS), 143 cases of TL-GPS (preservation rate, 98.3%) and nine conversions to laparoscopic cholecystectomy. The surgeries were all performed by one medical team and the mean operating time was 72 min. All macroscopic calculi were removed through endoscopy. The number of calculi observed in the patients was between one and several dozen; diameters ranged between 0.1 and 2.5 cm. Only three cases of incisional infection were noted in the LA-GPS group and long-term follow-up showed a low recurrence rate of 1.2%. L-GPS is, therefore, an excellent approach to cure cholelithiasis and TL-GPS is a feasible and effective option that could avoid incisional complications. PMID:25574204

Gallstones, cholecystectomy, and risk of digestive system cancers.  

PubMed

Gallstones and cholecystectomy may be related to digestive system cancer through inflammation, altered bile flux, and changes in metabolic hormone levels. Although gallstones are recognized causes of gallbladder cancer, associations with other cancers of the digestive system are poorly established. We used the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database (1992-2005), which includes 17 cancer registries that cover approximately 26% of the US population, to identify first primary cancers (n = 236,850) occurring in persons aged ?66 years and 100,000 cancer-free population-based controls frequency-matched by calendar year, age, and gender. Odds ratios and 95% confidence intervals were calculated using logistic regression analysis, adjusting for the matching factors. Gallstones and cholecystectomy were associated with increased risk of noncardia gastric cancer (odds ratio (OR) = 1.21 (95% confidence interval (CI): 1.11, 1.32) and OR = 1.26 (95% CI: 1.13, 1.40), respectively), small-intestine carcinoid (OR = 1.27 (95% CI: 1.01, 1.60) and OR = 1.78 (95% CI: 1.41, 2.25)), liver cancer (OR = 2.35 (95% CI: 2.18, 2.54) and OR = 1.26 (95% CI: 1.12, 1.41)), and pancreatic cancer (OR = 1.24 (95% CI: 1.16, 1.31) and OR = 1.23 (95% CI: 1.15, 1.33)). Colorectal cancer risk associated with gallstones and cholecystectomy decreased with increasing distance from the common bile duct (P-trend < 0.001). Hence, gallstones and cholecystectomy are associated with the risk of cancers occurring throughout the digestive tract. PMID:24470530

Use of rigid tubal ligation scope: Serendipity in laparoscopic common bile duct exploration  

PubMed Central

AIM: To assess the feasibility, safety of rigid tubal ligation scope in laparoscopic common bile duct (CBD) exploration. MATERIALS AND METHODS: Rigid nephroscope was used for laparoscopic CBD exploration until one day we tried the same with the rigid tubal ligation scope, which was passed easily into CBD both proximally and distally visualising the interior of the duct for presence of stone that were removed using endoscopic retrograde cholangiopancreaticography (ERCP) basket. This serendipity led us to use this scope for numerous patients from then on. A total of 62 patients, including male and female, underwent laparoscopic CBD exploration after choledochotomy with rigid tubal ligation scope between March 2007 and December 2012 followed by cholecystectomy. All the patients had both cholelithiasis and choledocholithiasis with minimum duct diameter of 12 mm. A total of 48 patients were given T-tube through choledochotomy and closed, and the remaining 14 patients had primary closure of choledochotomy. RESULTS: There were no intra-operative complications in any of the patients like CBD injury or portal vein injury. Post-operatively graded clamping of T-tube was done and was removed after 15 days in the patients who were given T-tube. None had retained the stone after T-tube cholangiography, which was done before removing the tube. Mean duration of follow up was 6 months. No patients had any complaints during the follow up. CONCLUSION: Laparoscopic CBD exploration is also feasible with rigid tubal ligation scope. With experienced surgeons, CBD injury is very minimal and stone clearance can be achieved in almost all patients. This rigid tubal ligation scope can be an alternative to other rigid and flexible scopes. PMID:24761081

Presacral tumors are particularly rare in the adult. Schwannomas are neurogenic neoplasms, rarely occurring in the retroperitoneum and the pelvis. Presented herein are the cases of 2 female patients with chronic pelvic pain who were discovered to have presacral schwannomas and were managed laparoscopically. Laparoscopy is a safe and efficient option in approaching benign pelvic tumors and might offer the advantage of better visualization of structures due to the magnification of laparoscopic view, especially in narrow anatomic spaces.

Techniques in laparoscopic donor nephrectomy.  

PubMed

What's known on the subject? and What does the study add? Innovations in laparoscopic surgery have provided transplant surgeons with a range of techniques as well as a vast array of minimally invasive instruments. Whilst randomized control trials have compared open and laparoscopic donor nephrectomy, there is a paucity of high quality data comparing different laparoscopic approaches. This article summarizes the main techniques of laparoscopic donor nephrectomy currently in use and reviews the evidence available for each. In addition, controversial aspects of donor nephrectomy are examined, including the technological advances applicable to this operation. Increasing numbers of living donor kidney transplants are being performed worldwide, and the majority of donor operations are now laparoscopic. Transperitoneal 'pure' and hand-assisted laparoscopic donor nephrectomy are the two most commonly performed procedures, although retroperitoneal approaches are advocated by some centres. Controversy persists with respect to the technical aspects of donor nephrectomy, including both the approach and the method of ligation of the hilar vessels. More recently, robot-assisted, laparo-endoscopic single site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) -assisted donor nephrectomy have also been performed, further increasing the number of options available, but creating uncertainty as to the ideal approach.

Prophylactic cholecystectomy or expectant management for silent gallstones. A decision analysis to assess survival.  

PubMed

Decision analysis was done to compare the consequences of prophylactic cholecystectomy with expectant management for silent gallstone disease. Probability values were derived from a study of the natural history of silent gallstone disease, published cholecystectomy mortality rates, and life tables. The two strategies were compared by calculating cumulative numbers of person-years lost for hypothetical cohorts of men and women. Prophylactic cholecystectomy slightly decreases survival. A 30-year-old man choosing prophylactic cholecystectomy instead of expectant management would lose, on average, 4 days of life; a 50-year-old man would lose 18 days. Consideration of monetary costs and discounting further disfavors prophylactic cholecystectomy. Sensitivity analysis shows that differences between the two strategies remain small over a broad range of probability values, both for men and women. PMID:6881778

Laparoscopic port closure.  

PubMed

Formation of a post-operative trocar site hernia (TSH) is a serious complication of laparoscopic surgery with an incidence of 1.5%-1.8%, and may necessitate emergent surgical correction in the case of bowel strangulation. Many contributing factors increase the risk of this complication, and various surgical devices have been developed to help prevent post-operative TSH formation. Bladeless trocars with radially expanding technology have been shown to decrease the incidence of post-operative TSH. Various port site closure devices are also available on the market, which assist in closing the fascia, thus decreasing the risk of this complication. In this article, we will review the use of these devices and their potential to reduce post-operative TSH formation. PMID:24700212

Laparoscopic partial splenic resection.  

PubMed

Twenty domestic pigs with an average weight of 30 kg were subjected to laparoscopic partial splenic resection with the aim of determining the feasibility, reliability, and safety of this procedure. Unlike the human spleen, the pig spleen is perpendicular to the body's long axis, and it is long and slender. The parenchyma was severed through the middle third, where the organ is thickest. An 18-mm trocar with a 60-mm Endopath linear cutter was used for the resection. The tissue was removed with a 33-mm trocar. The operation was successfully concluded in all animals. No capsule tears occurred as a result of applying the stapler. Optimal hemostasis was achieved on the resected edges in all animals. Although these findings cannot be extended to human surgery without reservations, we suggest that diagnostic partial resection and minor cyst resections are ideal initial indications for this minimally invasive approach.

Laparoscopic ventral hernia repair.  

PubMed

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.

Focal fatty change of the segment IV of the liver has been attributed to local systemic venous inflow replacing the portal venous supply, which could develop or be accentuated after gastrectomy. However, focal fatty change due to aberrant pancreaticoduodenal vein that developed after cholecystectomy has never been reported. We report a 30-year-old man with such a rare lesion, which was initially misdiagnosed as a hepatocellular carcinoma, but was confirmed on computed tomography during selective gastroduodenal arteriography. The lesion disappeared 12 mo later without any intervention. PMID:25551000

[Laparoscopic surgery in day surgery].  

PubMed

Since ten years laparoscopic techniques have been employed as alternatives of many established open procedures in gynecologic, abdominal and finally urologic surgery. Laparoscopic techniques show significant advantages compared to open surgery, such as less hospitalization, reduced need of analgesic drugs, quick return to daily activities and far a better cosmetic results. Laparoscopic surgery has been advocated for urologic, uro-gynecologic and andrologic diseases. Since 1983 one-day surgery was proposed for only a few gynecologic and abdominal procedures and only recently for laparoscopic renal biopsy and abdominal testis evaluation. In these preliminary experiences the conditions for a correct management of laparoscopic one-day surgery have been clearly pointed out: 1. correct surgical indication; 2. through knowledge of surgical technique; 3. duration of the procedure less than 90 minutes; 4. correct anesthesia. Technique of anesthesia must be adapted to the surgical procedure required, its duration and the physical features of the patient. General anesthesia is usually preferred for either longer and more complex procedures or when a higher abdominal insufflation pressure is needed. Spinal or local anesthesia are preferred for simpler procedures or when only one trocar is required. At date only few urologic procedures seem to be suitable to one-day laparoscopic surgery. 1) Varicocele: although laparoscopic varicocelectomy in one-day surgery has never been reported previously, it can be performed in a short time, only 3 trocars are needed and insufflation pressure can be maintained within 15 mm Hg. 2) Renal biopsy and marsupialization of renal cysts. These are usually managed percutaneously but in some particular indications procedures under direct vision should be preferable. Both are short-lasting and only superficial general anesthesia is required; as surgical access is retroperitoneal only two trocars are sufficient; at date only renal biopsies have previously been reported. 3) Diagnostic procedures on abdominal testis. The procedure is brief only superficial general anesthesia is needed and only one trocar is required. Conclusions. One-day laparoscopic surgery will require in the future a more and more strict cooperation between urologists and anesthetists in order to tailor the correct anesthesiological and laparoscopic technique to the procedure required and the features of the patient.

[Laparoscopic and general surgery guided by open interventional magnetic resonance].  

PubMed

Interventional magnetic resonance (IMR) machines have produced unique opportunity for image-guided surgery. The open configuration design and fast pulse sequence allow virtual real time intraoperative scanning to monitor the progress of a procedure, with new images produced every 1.5 sec. This may give greater appreciation of anatomy, especially deep to the 2-dimensional laparoscopic image, and hence increase safety, reduce procedure magnitude and increase confidence in tumour resection surgery. The aim of this paper was to investigate the feasibility of performing IMR-image-guided general surgery, especially in neoplastic and laparoscopic field, reporting a single center -- St. Mary's Hospital (London, UK) -- experience. Procedures were carried out in a Signa 0.5 T General Elettric SP10 Interventional MR (General Electric Medical Systems, Milwaukee, WI, USA) with magnet-compatible instruments (titanium alloy instruments, plastic retractors and ultrasonic driven scalpel) and under general anesthesia. There were performed 10 excision biopsies of palpable benign breast tumors (on female patients), 3 excisions of skin sarcoma (dermatofibrosarcoma protuberans), 1 right hemicolectomy and 2 laparoscopic cholecystectomies. The breast lesions were localized with pre- and postcontrast (intravenous gadolinium DPTA) sagittal and axial fast multiplanar spoiled gradient recalled conventional Signa sequences; preoperative real time fast gradient recalled sequences were also obtained using the flashpoint tracking device. During right hemicolectomy intraoperative single shot fast spin echo (SSFSE) and fast spoiled gradient recalled (FSPGR) imaging of right colon were performed after installation of 150 cc of water or 1% gadolinium solution, respectively, through a Foley catheter; imaging was also obtained in an attempt to identify mesenteric lymph nodes intraoperatively. Concerning laparoscopic procedures, magnetic devices (insufflator, light source) were positioned outside scan room, the tubing and light head being passed through penetration panels. Intraoperative MR-cholangiography was performed using fast spin echo (SSFSE) techniques with minimal intensity projection 3-dimensional reconstruction. About skin sarcomas, 2 of them were skin recurrences of previously surgically treated sarcomas (all of them received preoperative biopsy) and the extent of the lesion was then determined using short tau inversion recovery (STIR) sequence. The skin was closed in each case without need for any plastic reconstruction. The breast lesions were visualized with both Signa and real-time imaging and all enhanced with contrast: 2 (20%) were visualized only after contrast enhancement; intraoperative real time imaging clearly demonstrated a resection margin in all cases. Maximum dimensions of breast specimens (range 8-50 mm, median 24.5 mm) were not significantly different from those measured by Signa (p>0.17, Student's paired t-test) or real time images (p>0.4): also there was no significant difference in lesion size between Signa and real time images (p>0.25). All postprocedure scans clearly demonstrated complete excision. The extent of the tumor at MR imaging was greater in each case than suggested by clinical examination. Adequate resection margins were planned using STIR sequences. Histological examination confirmed clear surgical margins of at least 1 cm in each case. During right hemicolectomy, both intraoperative SSFSE and FSPGR contrast imaging revealed the lesion and details of the colonic surface; imaging of the lymph node draining right colon was only partially successful, due to movement artifact. Concerning laparoscopic procedures, both FSE and SSFSE techniques produced reasonable images of the gallbladder and intrahepatic ducts, but the FSE imaging was of poor quality due to respiration artifact; however, SSFSE allowed visualization of the gallbladder and part of the common bile duct. About skin sarcomas, the extent of the tumor at MR imaging was greater in each case than suggested by clinical examination and in each case the com

Fibroids, Infertility and Laparoscopic Myomectomy  

PubMed Central

Objective: To review the literature and summarize the available evidence about the relationship of fibroids with infertility and to review the role of laparoscopic myomectomy in infertility. Materials and Methods: Medline, PubMed, and Cochrane Databases were searched for articles published between 1980 and 2010. Results: Fertility outcomes are decreased in women with submucosal fibroids, and myomectomy is of value. Subserosal fibroids do not affect fertility outcomes, and removal may not confer benefit. Intramural fibroids appear to decrease fertility, but the results of therapy are unclear. Although pregnancy rates for women with leiomyomata, managed endoscopically, are similar to those after laparotomy, there is a risk of uterine rupture. The risk is essentially unknown. Finally, the risk of recurrence seems higher after laparoscopic myomectomy compared to laparotomy. Conclusions: Laparoscopic myomectomy, when performed by an experienced surgeon, can be considered a safe technique, with an extremely low failure rate and good results in terms of the outcome of pregnancy.

The effect of cholecystectomy on bile salt metabolism  

PubMed Central

Isotopic bile salt studies have been performed in 13 cholecystectomy patients and 10 matched controls using labelled taurocholate and deoxycholic acid. Cholecystectomy subjects have reduced pools of both primary bile salts, cholate and chenodeoxycholate, while the deoxycholate pool remains normal in size. As a result of these changes, the total bile salt pool is reduced to almost half its normal size and deoxycholate becomes the predominant bile salt. The half-life of taurocholate is reduced but, because its pool size is diminished, the daily synthesis of taurocholate remains normal. There is accelerated transfer of 14C from taurocholate-24-14C to its metabolites in bile, especially deoxycholate conjugates. In four subjects studied pre- and postoperatively similar changes occurred in all the above parameters. All these data can be explained by the fact that the bile salt pool circulates during fasting as well as during digestion. The consequences of this are (1) increased exposure of bile salts to intestinal bacteria and hence increased bacterial degradation; (2) continuous passage of the bile salt pool through the liver, and therefore continuous and presumably enhanced feedback inhibition of hepatic bile salt synthesis. The reservoir function of the gallbladder influences the size, kinetics, metabolism, and composition of the bile salt pool. We suggest that no study of bile salt metabolism is complete without some assessment of gallbladder status. PMID:4758655

Laparoscopic live-donor nephrectomy.  

PubMed

Laparoscopic nephrectomy with ablative intent has been performed clinically. The current study aimed to determine whether a physiologically and anatomically intact kidney suitable for transplantation could be harvested laparoscopically. Three weeks after an ablative laparoscopic right nephrectomy, 15 pigs were divided into two groups: the study group (n = 10) underwent a laparoscopic live-donor left nephrectomy of the solitary kidney and conventional autotransplantation; the control group (n = 5) underwent an open live-donor left nephrectomy of the solitary kidney and conventional autotransplantation. All study kidneys underwent laparoscopic in situ hypothermic perfusion. The mean length of the left renal artery and vein were similar in the study and control groups: 3.1 cm and 3.4 cm, respectively, in the study group compared with 2.5 cm and 3.8 cm, respectively, in the control group (P = 0.5). No intraoperative renal vascular injuries or postoperative ureteral complications were noted in either group. Renal histopathologic examination immediately after live-donor nephrectomy and at 1 month post-transplant showed similar findings in the two groups. The mean serum creatinine at 7 and 30 days postoperatively was not significantly different: 2.1 mg/dL and 1.6 mg/dL, respectively, in the study group and 1.7 mg/dL, and 1.4 mg/dL, respectively, in the control group (P = 0.4). We conclude that laparoscopic live-donor nephrectomy can be performed safely and reproducibly in the porcine model. PMID:8061673

Laparoscopic reversal of Hartmann's procedure.  

PubMed

Reestablishing continuity after a Hartmann's procedure is considered a major surgical procedure with high morbidity/mortality. The aim of this study was to assess the short-/long-term outcome of laparoscopic restoration of bowel continuity after HP. A prospectively collected database of colorectal laparoscopic procedures (>800) performed between June 2005 and June 2013 was used to identify 20 consecutive patients who had undergone laparoscopic reversal of Hartmann's procedure (LHR). Median age was 65.4. Ten patients (50 %) had undergone surgery for perforated diverticulitis, 3 (15 %) for cancer, and 7 (35 %) for other reasons (volvulus, posttraumatic perforation, and sigmoid perforation from foreign body). Previous HP had been performed laparoscopically in only 3 patients. Median operative time was 162.5 min. All the procedures were completed laparoscopically. Intraoperative complication rate was nil. Post-operative mortality and morbidity were respectively 0 and 10 % (1 pneumonia, 1 bowel obstruction from post-anastomotic stenosis which required resection and redo of the anastomosis). Median time to first flatus was 3 days, to normal diet 5 days. Median hospital stay was 9 days without readmissions. We followed up the patients for a median of 44 months: when asked, all 20 (100 %) said they would undergo the operation (LHR) again; 3 (15 %) had been re-operated of laparoscopic mesh repair for incisional hernia. When performed by experienced surgeons, LHR is a feasible, safe, reproducible operation, which allows early return of bowel function, early discharge and fast return to work for the patient. It has a low morbidity rate. PMID:25262377

Design and Validation of an Augmented Reality System for Laparoscopic Surgery in a Real Environment  

PubMed Central

Purpose. This work presents the protocol carried out in the development and validation of an augmented reality system which was installed in an operating theatre to help surgeons with trocar placement during laparoscopic surgery. The purpose of this validation is to demonstrate the improvements that this system can provide to the field of medicine, particularly surgery. Method. Two experiments that were noninvasive for both the patient and the surgeon were designed. In one of these experiments the augmented reality system was used, the other one was the control experiment, and the system was not used. The type of operation selected for all cases was a cholecystectomy due to the low degree of complexity and complications before, during, and after the surgery. The technique used in the placement of trocars was the French technique, but the results can be extrapolated to any other technique and operation. Results and Conclusion. Four clinicians and ninety-six measurements obtained of twenty-four patients (randomly assigned in each experiment) were involved in these experiments. The final results show an improvement in accuracy and variability of 33% and 63%, respectively, in comparison to traditional methods, demonstrating that the use of an augmented reality system offers advantages for trocar placement in laparoscopic surgery.

Laparoscopic Surgery for Rectal Cancer  

PubMed Central

Laparoscopic surgery for rectal cancer is much more challenging than that for colon cancer because of the confined space within the pelvis. Further, because of the tumor's location in the pelvis, maintenance of resection margins is of greater concern. Nonrandomized studies by groups experienced in laparoscopic surgery have shown both that it produces short-term outcomes equivalent to those for open surgery and that it can be performed safely from an oncologic perspective. Nonsurgical complications appear to be fewer, but conversion to open surgery may become a real issue. This review summarizes these findings by addressing technical considerations, early outcomes, late outcomes, costs, and complications. PMID:21373245

Laparoscopic ultrasound and gastric cancer  

NASA Astrophysics Data System (ADS)

The management of gastrointestinal malignancies continues to evolve with the latest available therapeutic and diagnostic modalities. There are currently two driving forces in the management of these cancers: the benefits of minimally invasive surgery so thoroughly demonstrated by laparoscopic surgery, and the shift toward neoadjuvant chemotherapy for upper gastrointestinal cancers. In order to match the appropriate treatment to the disease, accurate staging is imperative. No technological advances have combined these two needs as much as laparascopic ultrasound to evaluate the liver and peritoneal cavity. We present a concise review of the latest application of laparoscopic ultrasound in management of gastrointestinal malignancy.

Painless Obstructive Jaundice Secondary to a Common Bile Duct Abscess: A Delayed Sequela of Cholecystectomy  

PubMed Central

Complications related to cholecystectomy are well described. Most occur in the early postoperative period and are recognised either at the time of, or shortly after surgery. Clinical sequelae occurring years following cholecystectomy are rare and infrequently reported. In addition, most delayed complications are related to the continuing presence or new formation of gallstones. In this paper we present a unique case of an abscess of the common bile duct wall, presenting with painless obstructive jaundice more than 30 years following an open cholecystectomy, without the presence of gallstones. The clinical presentation, investigations, and treatment are discussed with a review of other relevant reported cases in the literature. PMID:20052383

Ergonomic evaluation of laparoendoscopic single-site surgery ports in a validated laparoscopic training model.  

PubMed

Although laparoendoscopic single-site surgery (LESS) is feasible among expert laparoscopic surgeons, it poses many technical challenges not seen in conventional laparoscopy (CL). Recent technological advancements in single-incision instrumentation have created more interest and widespread usage of LESS. However, neither LESS nor its novel instrumentation have been thoroughly studied or evaluated using human factors and ergonomics techniques. Consequently, the aim of this study was to compare the physical performance of LESS to CL using a standardized task. Wrist and elbow angular movements, range of motion and physical discomfort were assessed for 24 novice participants. There were no significant differences for physical comfort/discomfort ratings or elbow and wrist flexion/extension range of motion between CL and LESS. However, wrist radial/ulnar range of motion was significantly greater in LESS compared to CL (p < 0.05). Additionally, wrist radial/ ulnar range of motion was significantly greater using the SILS Port compared to the GelPOINT (p < 0.05). Although further investigation is needed, LESS resulted in greater wrist deviation and range of motion due to the close proximity of the instruments, restrictive nature of the single-port devices, and the need to achieve adequate instrument triangulation and visualization.

Emergency cholecystectomy and hepatic arterial repair in a patient presenting with haemobilia and massive gastrointestinal haemorrhage due to a spontaneous cystic artery gallbladder fistula masquerading as a pseudoaneurysm  

PubMed Central

Background Haemobilia usually occurs secondary to accidental or iatrogenic hepatobiliary trauma. It can occasionally present with cataclysmal upper gastrointestinal haemorrhage posing as a life threatening emergency. Haemobilia can very rarely be a complication of acute cholecystitis. Here we report a case of haemobilia manifesting as massive gastrointestinal haemorrhage in a patient without any prior history of biliary surgery or intervention and present a brief review of literature. Case presentation A 22 year old male admitted with history suggestive of acute cholecystitis subsequently developed waxing waning jaundice and recurrent episodes of upper gastrointestinal bleed. Endoscopy showed an ulcer in the first part of duodenum with a clot, no active bleed was visible. Angiography was suggestive of a ruptured pseudoaneurysm in the vicinity of the right hepatic artery probably originating from the cystic artery. Coil embolization was tried but the coil dislodged into the right branch of hepatic artery distal to the site of pseudoaneurysm. Review of angiographic video in light of operative findings demonstrated a fistulous communication between cystic artery and gallbladder as the cause, a simultaneous cholecystoduodenal fistula was also noted. Retrograde cholecystectomy, closure of cholecystoduodenal fistula and right hepatic arteriotomy with retrieval of the endo-coil and hepatic arterial repair was performed. Conclusion Fistula between the cystic artery and gallbladder has been commonly reported to occur after laparoscopic cholecystectomy. Spontaneous fistulous communication, i.e. in the absence of any prior trauma or intervention, between cystic artery and gallbladder is rare with very few reports in literature. Aetiopathogenesis of the disease, in the context of current literature is reviewed. The diagnostic dilemma posed by the confounding finding of an ulcer in the duodenum, the iconic video angiographic depiction as also the therapeutic challenge of a failed embolization with consequent microcoil migration and primary hepatic arterial repair in the emergency situation is discussed.

Characterization of a near-infrared laparoscopic hyperspectral imaging system for minimally invasive surgery.  

PubMed

We developed and characterized a new imaging platform for minimally invasive surgical venues, specifically a system to help guide laparoscopic surgeons to visualize biliary anatomy. This platform is a novel combination of a near-infrared hyperspectral imaging system coupled with a conventional surgical laparoscope. Intraoperative tissues are illuminated by optical fibers arranged in a ring around a center-mounted relay lens collecting back-reflected light from tissues to the hyperspectral imaging system. The system consists of a focal plane array (FPA) and a liquid crystal tunable filter, which is continuously tunable in the near-infrared spectral range of 650-1100 nm with the capability of passing light with a mean bandwidth of 6.95 nm, and the FPA is a high-sensitivity back-illuminated, deep depleted charge-coupled device. Placing a standard resolution target 5.1 cm from the distal end of the laparoscope, a typical intraoperative working distance, produced a 7.6-cm-diameter field of view with an optimal spatial resolution of 0.24 mm. In addition, the system's spatial and spectral resolution and its wavelength tuning accuracy are characterized. The spectroscopic images are formatted into a three-dimensional hyperspectral image cube and processed using principle component analysis. The processed images provide contrast based on measured spectra associated with chemically different anatomical structures helping identify the main molecular chromophores inherent to each tissue. The principal component images were found to image swine gallbladder and biliary structures from surrounding tissues, in real time, during cholecystectomy surgery. Furthermore, it is shown that surgeons can interrogate selected image subregions for their molecular composition identifying biliary anatomy during surgery and before any invasive action is undertaken.

[Laparoscopic colo-rectal surgery].  

PubMed

Laparoscopic colorectal surgery was less invasive for patients although it was difficult to perform complete resection of colon combined with regional lymph node. The skillful manner of the laparoscopic surgery was required for the surgical team. The laparoscopic equipments, in order to perform curative dissection of mesenterium and intermediate lymph node, such as Ultrasonic-aspiration surgical unit (USU) or Harmonic scalpel laparoscopic coagulation shears (LCS), were useful for safer dissection of D2 regional lymph node. Meticulous manner of grasping forceps and special dissectors was made sufficient lymph node dissection. The reconstruction of extracorporeal anastomotic technique by hand or valtrac (biofragmentable anastomosis ring) were safer manner for anastomosis after resection of the right side colon. Reconstruction by double stapling technique of linear stapler and circular stapler was admired for anastomosis for left side colonic and rectal surgery. We had safely performed locar resection in 3, partial resection with Do dissection in 2, with D1 dissection in 14, with D2 dissection in 21 and right and left hemicolectomy in 1 each. PMID:8965357

Radionuclide evaluation of bile leakage and the use of subhepatic drains after cholecystectomy.  

PubMed

Our study addresses the question of efficacy of drainage after cholecystectomy by evaluation of the leakage of radiolabeled bile. Based on our data, drains placed at the time of surgery do not appear to reliably remove bile or to decrease morbidity. Our study reveals that bile leakage after cholecystectomy is frequent, cannot be accurately predicted at operation, is not related to the experience of the operating surgeons, and does not necessarily correlate with morbidity. The shorter postoperative hospital stay in the group of patients with subhepatic bile leakage compared with the group without evidence of leakage after cholecystectomy is not statistically significant. However, this trend does suggest that there is no increase in morbidity associated with bile leakage per se. A large, clinically significant bile leak can easily be treated by modern interventional radiologic techniques if drainage is indicated. A larger, double-blind study is necessary to further evaluate the issues surrounding bile leakage and drainage after cholecystectomy. PMID:3946761

Buprenorphine versus morphine for patient-controlled analgesia after cholecystectomy.  

PubMed

Buprenorphine is an opioid agonist-antagonist that has emerged as an option for postoperative analgesia. We compared the postoperative hospital course of patients undergoing open cholecystectomy who received buprenorphine hydrochloride with those who received morphine sulfate. Patients in both groups administered the analgesic using a patient-controlled analgesia infusion device. Comparison of the two groups demonstrated no difference with respect to clinical indicators of intestinal motility, visual analog pain scores and hospitalization period. Postoperative nausea occurred more frequently in the buprenorphine group, but the difference was not significant. We concluded that the patient-controlled analgesia device is a valuable tool for comparing different analgesics. Both analgesics tested provide adequate analgesia with a similar postoperative course.

Pure laparoscopic hepatectomy as repeat surgery and repeat hepatectomy  

PubMed Central

AIM: To assess clinical outcomes of laparoscopic hepatectomy (LH) in patients with a history of upper abdominal surgery and repeat hepatectomy. METHODS: This study compared the perioperative courses of patients receiving LH at our institution that had or had not previously undergone upper abdominal surgery. Of the 80 patients who underwent LH, 22 had prior abdominal surgeries, including hepatectomy (n = 12), pancreatectomy (n = 3), cholecystectomy and common bile duct excision (n = 1), splenectomy (n = 1), total gastrectomy (n = 1), colectomy with the involvement of transverse colon (n = 3), and extended hysterectomy with extensive lymph-node dissection up to the upper abdomen (n = 1). Clinical indicators including operating time, blood loss, hospital stay, and morbidity were compared among the groups. RESULTS: Eighteen of the 22 patients who had undergone previous surgery had severe adhesions in the area around the liver. However, there were no conversions to laparotomy in this group. In the 58 patients without a history of upper abdominal surgery, the median operative time was 301 min and blood loss was 150 mL. In patients with upper abdominal surgical history or repeat hepatectomy, the operative times were 351 and 301 min, and blood loss was 100 and 50 mL, respectively. The median postoperative stay was 17, 13 and 12 d for patients with no history of upper abdominal surgery, patients with a history, and patients with repeat hepatectomy, respectively. There were five cases with complications in the group with no surgical history, compared to only one case in the group with a prior history. There were no statistically significant differences in the perioperative results between the groups with and without upper abdominal surgical history, or with repeat hepatectomy. CONCLUSION: LH is feasible and safe in patients with a history of upper abdominal surgery or repeat hepatectomy. PMID:25624731

Laparoscopic approach to retrorectal cyst.  

PubMed

Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomograghy (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space. PMID:19030218

Laparoscopic pancreatectomy: Indications and outcomes  

PubMed Central

The application of minimally invasive approaches to pancreatic resection for benign and malignant diseases has been growing in the last two decades. Studies have demonstrated that laparoscopic distal pancreatectomy (LDP) is feasible and safe, and many of them show that compared to open distal pancreatectomy, LDP has decreased blood loss and length of hospital stay, and equivalent post-operative complication rates and short-term oncologic outcomes. LDP is becoming the procedure of choice for benign or small low-grade malignant lesions in the distal pancreas. Minimally invasive pancreaticoduodenectomy (MIPD) has not yet been widely adopted. There is no clear evidence in favor of MIPD over open pancreaticoduodenectomy in operative time, blood loss, length of stay or rate of complications. Robotic surgery has recently been applied to pancreatectomy, and many of the advantages of laparoscopy over open surgery have been observed in robotic surgery. Laparoscopic enucleation is considered safe for patients with small, benign or low-grade malignant lesions of the pancreas that is amenable to parenchyma-preserving procedure. As surgeons’ experience with advanced laparoscopic and robotic skills has been growing around the world, new innovations and breakthrough in minimally invasive pancreatic procedures will evolve.

Understanding and optimizing laparoscopic videosystems.  

PubMed

As tactile feedback and degree of freedom for instrument movement are restricted in laparoscopic surgery, the video image plays the most crucial role in giving the surgeon information about the performance of the operation. The development of small, reliable, high-resolution imaging systems is essential for the surgeon's acquisition detailed information about the tissues being manipulated. Image quality depends on each component of the laparoscopic imaging unit. In this context, it is crucial for the surgeon to have an understanding of how the video signal is formed, transmitted, and displayed. Moreover, the surgeon also needs to have an idea about the basic principles and specifications of the surgical video systems (i.e. charge-coupled device (CCD) camera, monitors, and digitizers). This knowledge is essential for choosing pieces of equipment and knowing how to assemble them into a functional operating suite. The aim of this review is to provide the surgeon with the basics of video signaling, and to familiarize him or her with the technical principles of the surgical video systems. An insight into the future of laparoscopic video systems also is made, and practical tips for improving image quality and troubleshooting are given throughout the article. PMID:11443427

D-light for laparoscopic fluorescence diagnosis  

NASA Astrophysics Data System (ADS)

To evaluate the role of ALA induced fluorescence diagnosis in laparoscopic surgery, we induced peritoneal carcinosis in rats by multilocular intraabdominal tumorcell implantation (CC531). The animals were photosensitized by intraabdominal ALA lavage. Laparoscopy was performed with both, conventional white and then blue light (D-Light, KARL STORZ Germany) excitation. Laparoscopy with conventional white light showed peritoneal carcinoma foci from 0.1 to 2 cm in diameter. All macroscopically visible tumors (n equals 142) were fluorescence positive after laparoscopic blue light excitation. In addition, 30 laparoscopic not visible (white light) tumors showed fluorescence and were histologically confirmed as colon carcinoma metastases. We conclude that only ALA induced laparoscopic fluorescence detection after blue light excitation is the adequate method to detect the entire extent of the intraabdominal tumor spread. Fluorescence laparoscopy is essential for laparoscopic staging of colorectal cancer because of a higher rate of cancer foci detection.

Laparoscopic Appendectomy and Minilaparoscopic Approach: A Retrospective Review After 8-Years' Experience  

PubMed Central

Background: This is a presentation of our 8-year experience in laparoscopic appendectomy, showing complications and results to determine the advantages and efficacy of laparoscopy. Methods: We used this technique from December 1990 to December 1998 on 282 consecutive and non-selected patients (169 females and 113 males) with an average age of 24 years (range 5-86 years). All patients were suffering from sub-acute appendicitis or chronic appendicopathies, except for 84 (29.7%) cases of acute appendicitis and 25 (8.9%) cases of gangrenous appendicitis with peritonitis. All patients with suspected appendicitis were evaluated with a laparoscopic exploration. Results: In 39 patients (13.9%), appendectomy was performed along with 19 enucleated or endocoagulated ovarian cysts, 8 adhesiolyses, 6 transperitoneal hernioplasties (4 right and 2 left), 2 cholecystectomies, 2 excisions of a Meckel diverticulum, 1 aspiration and suture of a right tubal pregnancy and 1 electrodesiccation of pelvic endometriosis. Thirty-five patients (12.5%) revealed the presence of a gynecological-type pathology. We performed 2 (0.7%) conversions to open exploration and experienced 6 (2.1%) complications, of which only 1 (0.35%) was a major complication: a delayed hemoperitoneum (1 liter), re-operated elsewhere, the cause of which was not identified. We performed 4 (1.4%) relaparoscopies for retrocecal abscess (three patients with primary gangrenous appendicitis and peritonitis presenting with an abscess in the right iliac fossa and in one patient with widespread intestinal adhesions with primary acute appendicitis). No patient with a diagnosis of a normal appendix developed an intraperitoneal abscess. Mortality was non-existent. The postoperative course, which was subjectively better than in cases operated in the traditional way, was, on an average, 2 days (range 1-18 days) for appendectomies carried out with the traditional laparoscopic technique and 1 day for appendectomies carried out with the minilaparoscopic technique (6 patients). Conclusion: We believe that the laparoscopic technique can handle any type of clinical situation, as it can cure several pathologies during the same session with minimal trauma and maximum benefit for the patient.

Cholecystectomy and Diagnosis-Related Groups (DRGs): patient classification and hospital reimbursement in 11 European countries  

PubMed Central

Background: As part of the EuroDRG project, researchers from eleven countries (i.e. Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Sweden, and Spain) compared how their Diagnosis-Related Groups (DRG) systems deal with cholecystectomy patients. The study aims to assist surgeons and national authorities to optimize their DRG systems. Methods: National or regional databases were used to identify hospital cases with a procedure of cholecystectomy. DRG classification algorithms and indicators of resource consumption were compared for those DRGs that individually contained at least 1% of cases. Six standardised case vignettes were defined, and quasi prices according to national DRG-based hospital payment systems were ascertained and compared to an index case. Results: European DRG systems vary widely: they classify cholecystectomy patients according to different sets of variables into diverging numbers of DRGs (between two DRGs in Austria and Poland to nine DRGs in England). The most complex DRG is valued at four times more resource intensive than the index case in Ireland but only 1.3 times more resource intensive than the index case in Austria. Conclusion: Large variations in the classification of cholecystectomy patients raise concerns whether all systems rely on the most appropriate classification variables. Surgeons, hospital managers and national DRG authorities should consider how other countries’ DRG systems classify cholecystectomy patients in order to optimize their DRG systems and to ensure fair and appropriate reimbursement.

Indocyanine-green-loaded microballoons for biliary imaging in cholecystectomy  

PubMed Central

Abstract. We encapsulate indocyanine green (ICG) in poly[(D,L-lactide-co-glycolide)-co-PEG] diblock (PLGA-PEG) microballoons for real-time fluorescence and hyperspectral imaging of biliary anatomy. ICG-loaded microballoons show superior fluorescence characteristics and slower degradation in comparison with pure ICG. The use of ICG-loaded microballoons in biliary imaging is demonstrated in both biliary-simulating phantoms and an ex vivo tissue model. The biliary-simulating phantoms are prepared by embedding ICG-loaded microballoons in agar gel and imaged by a fluorescence imaging module in a Da Vinci surgical robot. The ex vivo model consists of liver, gallbladder, common bile duct, and part of the duodenum freshly dissected from a domestic swine. After ICG-loaded microballoons are injected into the gallbladder, the biliary structure is imaged by both hyperspectral and fluorescence imaging modalities. Advanced spectral analysis and image processing algorithms are developed to classify the tissue types and identify the biliary anatomy. While fluorescence imaging provides dynamic information of movement and flow in the surgical region of interest, data from hyperspectral imaging allow for rapid identification of the bile duct and safe exclusion of any contaminant fluorescence from tissue not part of the biliary anatomy. Our experiments demonstrate the technical feasibility of using ICG-loaded microballoons for biliary imaging in cholecystectomy. PMID:23214186

Bowel function and irritable bowel symptoms after hysterectomy and cholecystectomy--a population based study.  

PubMed Central

Because unsubstantiated beliefs link hysterectomy and cholecystectomy with bowel function, this study examined all the women who had had these operations in a defined population (79 and 37 respectively, out of 1058) with respect to bowel habits, irritable bowel syndrome symptoms, and whole gut transit time calculated from records of three defecations. Compared with unoperated controls, women after hysterectomy were more likely to consider themselves constipated; they also strained more and admitted more often to bloating and feelings of incomplete evacuation. Their stools tended to be lumpier and, in women over 50 years, transit time was longer. When women treated by cholecystectomy were compared with women having newly discovered, asymptomatic gall stones, they more often described defecation as urgent but had no other detectable differences. In conclusion symptomatic constipation is frequent in women after hysterectomy; after cholecystectomy, bowel habit is not consistently changed but the rectum seems to be more irritable. PMID:8174964

A radionuclide study on the effectiveness of drainage after elective cholecystectomy.  

PubMed Central

Passive drainage after elective cholecystectomy was studied in six patients. Their erythrocytes were labeled in vitro with technetium-99mTc and injected via the drain after operation. After one hour, we were able to recover labeled erythrocytes and free pertechnetate from peripheral blood. After 24 hours, a large part of the injected erythrocytes had been evacuated via the drain. In eight patients subjected to cholecystectomy, 99mTc-HIDA was injected intravenously after the operation. In four cases, in which the gallbladder bed was raw, the activity ratio discharge/blood rapidly reached extremely high values. In the other four cases, in which the liver surface had not been denuded, the ratio was much lower. Passive drainage is a useful device for evacuation intra-abdominal bile or hemolysed blood after cholecystectomy, especially when the gallbladder bed has been denuded. Images Fig. 1a. Fig. 1b.

Ursodeoxycholic acid exerts no beneficial effect in patients with symptomatic gallstones awaiting cholecystectomy.  

PubMed

Ursodeoxycholic acid (UDCA) and impaired gallbladder motility purportedly reduce biliary pain and acute cholecystitis in patients with gallstones. However, the effect of UDCA in this setting has not been studied prospectively. This issue is important, as in several countries (including the Netherlands) scheduling problems result in long waiting periods for elective cholecystectomy. We conducted a randomized, double-blind, placebo-controlled trial on effects of UDCA in 177 highly symptomatic patients with gallstones scheduled for cholecystectomy. Patients were stratified for colic number in the preceding year (<3: 32 patients; > or =3: 145 patients). Baseline postprandial gallbladder motility was measured by ultrasound in 126 consenting patients. Twenty-three patients (26%) receiving UDCA and 29 (33%) receiving placebo remained colic-free during the waiting period (89 +/- 4; median [range]: 75[4-365] days) before cholecystectomy (P = .3). Number of colics, non-severe biliary pain, and analgesics intake were comparable. A low number of prior colics was associated with a higher likelihood of remaining colic-free (59% vs. 23%, P < .001), without effects on the risk of complications. In patients evaluated for gallbladder motility, 57% were weak and 43% were strong contractors (minimal gallbladder volume > respectively < or = 6 mL). Likelihood to remain colic-free was comparable in strong and weak contractors (31% vs. 33%). In weak contractors, UDCA decreased likelihood to remain colic-free (21% vs. 47%, P = .02). In the placebo group, 3 preoperative and 2 post-cholecystectomy complications occurred. In contrast, all 4 complications in the UDCA group occurred after cholecystectomy. In conclusion, UDCA does not reduce biliary symptoms in highly symptomatic patients. Early cholecystectomy is warranted in patients with symptomatic gallstones. PMID:16729326

Laparoscopic approach to Meckel's diverticulum  

PubMed Central

AIM: To retrospective review the laparoscopic management of Meckel Diverticulum (MD) in two Italian Pediatric Surgery Centers. METHODS: Between January 2002 and December 2012, 19 trans-umbilical laparoscopic-assisted (TULA) procedures were performed for suspected MD. The children were hospitalized for gastrointestinal bleeding and/or recurrent abdominal pain. Median age at diagnosis was 5.4 years (range 6 mo-15 years). The study included 15 boys and 4 girls. All patients underwent clinical examination, routine laboratory tests, abdominal ultrasound and technetium-99m pertechnetate scan, and patients with bleeding underwent gastrointestinal endoscopy. The abdominal exploration was performed with a 10 mm operative laparoscope. Pneumoperitoneum was established based on the body weight. Systematic overview of the peritoneal cavity allowed the ileum to be grasped with an atraumatic instrument. The complete exploration and surgical treatment of MD were performed extracorporeally, after intestinal exteriorization through the umbilicus. All patients’ demographics, main clinical features, diagnostic investigations, operative time, histopathology reports, conversion rate, hospital stay and complications were registered and analyzed. RESULTS: MD was identified in 17 patients, while 1 had an ileal duplication and 1 a jejunal hemangioma. Fifteen patients had painless intestinal bleeding, while 4 had recurrent abdominal pain and exhibited cyst like structures in an ultrasound study. Eleven patients had a positive technetium-99m pertechnetate scan. In the patients with bleeding, gastrointestinal endoscopy did not name the source of hemorrhage. All patients were subjected to a TULA surgical procedure. An intestinal resection/anastomosis was performed in 14 patients, while 4 had a wedge resection of the diverticulum and 1 underwent stapling diverticulectomy. All surgical procedures were performed without conversion to open laparotomy. Mean operative time was 75 min (range 40-115 min). No major surgical complications were recorded. The median hospital stay was 5-7 d (range 4-13 d). All patients are asymptomatic at a median follow up of 4, 5 years (range 10 mo-10 years). CONCLUSION: Trans-umbilical laparoscopic-assisted Meckel’s diverticulectomy is safe and effective in the treatment of MD, with excellent results. PMID:25009390

Laparoscopic repair of complicated umbilical hernia with Strattice Laparoscopic™ reconstructive tissue matrix  

PubMed Central

INTRODUCTION Complex hernias continue to present a challenge. Surgical techniques for repair are carefully considered to reduce risk for complications. Laparoscopic repairs improve postoperative infection rates, and placement of biologic mesh decreases mesh infection rates. However, laparoscopic repairs using biologic mesh is generally challenging due to difficulty with maneuverability. PRESENTATION OF CASE We present a case of a complex ventral hernia that was laparoscopically repaired using a new FDA cleared laparoscopic biologic graft. The patient had multiple comorbidities, including obesity, hepatitis C, endocarditis secondary to IV drug use, tobacco smoking, bilateral inguinal hernia, and recurrent umbilical hernia. The recurrent hernia was larger, irreducible, and discolored compared to original defect. The patient underwent laparoscopic repair with primary closure and reinforcement with Strattice™ Tissue Matrix Laparoscopic (LifeCell Corporation, Branchburg, NJ). At nine months postoperative, the patient had no evidence of recurrence, infection, or chronic pain, demonstrating early success from the surgical management. DISCUSSION Presence of multiple comorbidities and incarcerated recurrent hernia increase risk for complications during and/or after hernia repair. Considering these factors, laparoscopic repair with Strattice Laparoscopic and defect closure was a reasonable technique for repair. CONCLUSION Laparoscopic suture repair reinforced with biologic dermal tissue matrix was successfully performed during a complex hernia repair. PMID:25437666

Laparoscopic Heminephrectomy of a Horseshoe Kidney  

PubMed Central

Minimally invasive surgery has revolutionized surgery for urologic disorders, and laparoscopic procedures have become widely available for several different ablative and reconstructive operations. Laparoscopic heminephrectomy in patients with horseshoe kidney can be a technically challenging procedure due to aberrant vessels, functional parenchyma in the isthmus, and abnormal location. We report the management of a case of symptomatic nonfunctioning left moiety of a horseshoe kidney with emphasis on its surgical technique combined with a review of the literature. Laparoscopic heminephrectomy is a feasible option in the surgical management of benign and malignant conditions of the horseshoe kidney and can be performed safely using a transperitoneal or a retroperitoneal approach.

Low-pressure pneumoperitoneum during laparoscopic donor nephrectomy to optimize live donors' comfort.  

PubMed

Nowadays, laparoscopic donor nephrectomy (LDN) has become the gold standard to procure live donor kidneys. As the relationship between donor and recipient loosens, it becomes of even greater importance to optimize safety and comfort of the surgical procedure. Low-pressure pneumoperitoneum has been shown to reduce pain scores after laparoscopic cholecystectomy. Live kidney donors may also benefit from the use of low pressure during LDN. To evaluate feasibility and efficacy to reduce post-operative pain, we performed a randomized blinded study. Twenty donors were randomly assigned to standard (14 mmHg) or low (7 mmHg) pressure during LDN. One conversion from low to standard pressure was indicated by protocol due to lack of progression. Intention-to-treat analysis showed that low pressure resulted in a significantly longer skin-to-skin time (149 ± 86 vs. 111 ± 19 min), higher urine output during pneumoperitoneum (23 ± 35 vs. 11 ± 20 mL/h), lower cumulative overall pain score after 72 h (9.4 ± 3.2 vs. 13.5 ± 4.5), lower deep intra-abdominal pain score (11 ± 3.3 vs. 7.5 ± 3.1), and a lower cumulative overall referred pain score (1.8 ± 1.9 vs. 4.2 ± 3). Donor serum creatinine levels, complications, and quality of life dimensions were not significantly different. Our data show that low-pressure pneumoperitoneum during LDN is feasible and may contribute to increase live donors' comfort during the early post-operative phase. PMID:23795745

Serum cystatin C is a sensitive early marker for changes in the glomerular filtration rate in patients undergoing laparoscopic surgery  

PubMed Central

OBJECTIVE: Pneumoperitoneum during laparoscopy results in transient oliguria and decreased glomerular filtration and renal blood flow. The presence of oliguria and elevated serum creatinine is suggestive of acute renal injury. Serum cystatin C has been described as a new marker for the detection of this type of injury. In this study, our aim was to compare the glomerular filtration rate estimated using cystatin C levels with the rate estimated using serum creatinine in patients with normal renal function who were undergoing laparoscopic surgery. METHODS: In total, 41 patients undergoing laparoscopic cholecystectomy or hiatoplasty were recruited for the study. Blood samples were collected at three time intervals: first, before intubation (T1); second, 30 minutes after the establishment of pneumoperitoneum (T2); and third, 30 minutes after deflation of the pneumoperitoneum (T3). These blood samples were then analyzed for serum cystatin C, creatinine, and vasopressin. The Larsson formula was used to calculate the glomerular filtration rate based on the serum cystatin C levels, and the Cockcroft-Gault formula was used to calculate the glomerular filtration rate according to the serum creatinine levels. RESULTS: Serum cystatin C levels increased during the study (T1?=?T2T3; p<0.05). The calculated eGlomerular filtration rate-Larsson decreased, whereas the eGlomerular filtration rate-Cockcroft-Gault increased. There was no correlation between cystatin C and serum creatinine. Additionally, Pearson's analysis showed a better correlation between serum cystatin C and the eGlomerular filtration rate than between serum creatinine and the eGlomerular filtration rate. CONCLUSION: This study demonstrates that serum cystatin C is a more sensitive indicator of changes in the glomerular filtration rate than serum creatinine is in patients with normal renal function who are undergoing laparoscopic procedures.

Laparoscopic Liver Mobilization: Tricks of the Trade to Avoid Complications  

PubMed Central

Laparoscopic liver resection is gaining popularity because of the availability of new laparoscopic instruments and advanced techniques. Laparoscopic liver mobilization is not only necessary for pure laparoscopic liver resection but also for laparoscopy-assisted hepatectomy. Laparoscopy-assisted hepatectomy significantly reduces the length of the laparotomy incision, and it is a good educational transition to the more advanced laparoscopic liver resection. Laparoscopic liver mobilization is a simple and easy procedure if surgeons know what challenges to expect. Here, the technique of liver mobilization is summarized, along with those challenges.

Perineal robot-assisted laparoscopic radical prostatectomy (P-RALP): feasibility study in the cadaver model.  

PubMed

Objective: To evaluate the feasibility of perineal robot-assisted laparoscopic radical prostatectomy (P-RALP) in the cadaver model. Methods: The prostate was assessed by ultrasound and cystoscopy in lithotomy. After incision and subcutaneous dissection, a single-port device was placed and the robot was docked. The rectourethralis muscle was divided and the levator ani fibers were split. The Denonvilliers' fascia was incised and the posterior prostate and seminal vesicles were dissected. The apex was dissected and the urethra was transected. The anterior and lateral planes were dissected and the prostate pedicles were clipped. The prostate was freed from the bladder neck and the vesicourethral anastomosis was performed. The robot was undocked and the wound was sutured in layers. Cystoscopy confirmed integrity of the anastomosis. The specimen was sent for histopathology exam. Results: Nerve-sparing P-RALP was successfully completed in 3 cadavers. Median time for setting was 23 min. Time for posterior dissection was 15 min. Dissection of the apex and section of the urethra took 9 min. Time for antero-lateral dissection was 14 min. Time for bladder neck dissection was 7 min. Vesicourethral anastomosis took 8 min. Total operative time was 89 min. The prostate capsule was grossly intact and histopathology exam was negative for prostatic tissue in all distal urethral sections and in two out of three bladder neck sections. Conclusions: P-RALP is feasible in the cadaver. Future studies should evaluate the feasibility of lymph node dissection through the same incision, clinical feasibility, and prospective comparisons with standard techniques. PMID:25083743

Cholecystectomy after breast reconstruction with a pedicled autologous tram flap. Types of surgical access.  

PubMed

The number of breast reconstruction procedures has been increasing in recent years. One of the suggested treatment methods is breast reconstruction with a pedicled skin and muscle TRAM flap (transverse rectus abdominis muscle - TRAM). Surgical incisions performed during a cholecystectomy procedure may be located in the areas significant for flap survival. The aim of this paper is to present anatomical changes in abdominal walls secondary to pedicled skin and muscle (TRAM) flap breast reconstruction, which influence the planned access in cholecystectomy procedures. The authors present 2 cases of cholecystectomy performed due to cholelithiasis in female patients with a history of TRAM flap breast reconstruction procedures. The first patient underwent a traditional method of surgery 14 days after the reconstruction due to acute cholecystitis. The second patient underwent a laparoscopy due to cholelithiasis 7 years after the TRAM procedure. In both cases an abdominal ultrasound scan was performed prior to the operation, and surgical access was determined following consultation with a plastic surgeon. The patient who had undergone traditional cholecystectomy developed an infection of the postoperative wound. The wound was treated with antibiotics, vacuum therapy and skin grafting. After 7 weeks complete postoperative wound healing and correct healing of the TRAM flap were achieved. The patient who had undergone laparoscopy was discharged home on the second postoperative day without any complications. In order to plan a safe surgical access, it is necessary to know the changes in the anatomy of abdominal walls following a pedicled TRAM flap breast reconstruction procedure. PMID:25337177

Pure Laparoscopic and Robot-Assisted Laparoscopic Reconstructive Surgery in Congenital Megaureter: A Single Institution Experience  

PubMed Central

To report our experience of pure laparoscopic and robot-assisted laparoscopic reconstructive surgery in congenital megaureter, seven patients (one bilateral) with symptomatic congenital megaureter underwent pure laparoscopic or robot-assisted laparoscopic surgery. The megaureter was exposed at the level of the blood vessel and was isolated to the bladder narrow area. Extreme ureter trim and submucosal tunnel encapsulation or papillary implantations and anti-reflux ureter bladder anastomosis were performed intraperitoneally by pure laparoscopic or robot-assisted laparoscopic surgery. The clinical data of seven patients after operation were analyzed, including the operation time, intraoperative complications, intraoperative bleeding volumes, postoperative complications, postoperative hospitalization time and pathological results. All of the patients were followed. The operation was successfully performed in seven patients. The mean operation times for pure laparoscopic surgery and robotic-assistant laparoscopic surgery were 175 (range: 150–220) and 187 (range: 170–205) min, respectively, and the mean operative blood loss volumes were 20 (range: 10–30) and 28.75 (range: 15–20) ml, respectively. There were no intraoperative complications. The postoperative drainage time was 5 (range: 4–6) and 5.75 (range: 5–6) d, respectively, and the indwelling catheter time was 6.33 (range: 4–8) d and 7 (range: 7–7) d, respectively. The postoperative hospitalization time was 7.67 (range: 7–8) d and 8 (range: 7–10) d, respectively. There was no obvious pain, no secondary bleeding and no urine leakage after the operation. Postoperative pathology reports revealed chronic urothelial mucosa inflammation. The follow-up results confirmed that all patients were relieved of their symptoms. Both pure laparoscopic and robot-assisted laparoscopic surgery using different anti-reflux ureter bladder anastomoses are safe and effective approaches in the minimally invasive treatment of congenital megaureter.

Laparoscopic intracorporeal distal rectal transection with the CONTOUR(®) device.  

PubMed

Laparoscopic rectal resection is considered technically more demanding than laparoscopic colectomy. Rectal transection is a challenging part of laparoscopic low anterior rectal resection and restorative proctocolectomy. We describe our technique for laparoscopic rectal transection with a curved cutter, a device initially designed for open surgery, combined with the use of a ring-mounted sterile drape that allows maintenance of sufficient intra-abdominal gas pressure in a series of 34 patients.

Risk of Primary Liver Cancer Associated with Gallstones and Cholecystectomy: A Meta-Analysis  

PubMed Central

Background Recent epidemiological evidence points to an association between gallstones or cholecystectomy and the incidence risk of liver cancer, but the results are inconsistent. We present a meta-analysis of observational studies to explore this association. Methods We identified studies by a literature search of PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and relevant conference proceedings up to March 2014. A random-effects model was used to generate pooled multivariable adjusted odds ratios (ORs) and 95% confidence intervals (CIs). Between-study heterogeneity was assessed using Cochran’s Q statistic and the I2. Results Fifteen studies (five case-control and 10 cohort studies) were included in this analysis. There were 4,487,662 subjects in total, 17,945 diagnoses of liver cancer, 328,420 exposed to gallstones, and 884,507 exposed to cholecystectomy. Pooled results indicated a significant increased risk of liver cancer in patients with a history of gallstones (OR?=?2.54; 95% CI, 1.71–3.79; n?=?11 studies), as well as cholecystectomy (OR?=?1.62; 95% CI, 1.29–2.02; n?=?12 studies), but there was considerable heterogeneity among these studies. The effects estimates did not vary markedly when stratified by gender, study design, study region, and study quality. The multivariate meta-regression analysis suggested that study region and study quality appeared to explain the heterogeneity observed in the cholecystectomy analysis. Conclusions Our results suggest that individuals with a history of gallstones and cholecystectomy may have an increased risk of liver cancer. PMID:25290940

Comparison of Surgical Skills in Laparoscopic and Robotic Tasks Between Experienced Surgeons and Novices in Laparoscopic Surgery: An Experimental Study  

PubMed Central

Purpose Robotic surgery is known to provide an improved technical ability as compared to laparoscopic surgery. We aimed to compare the efficiency of surgical skills by performing the same experimental tasks using both laparoscopic and robotic systems in an attempt to determine if a robotic system has an advantage over laparoscopic system. Methods Twenty participants without any robotic experience, 10 laparoscopic novices (LN: medical students) and 10 laparoscopically-experienced surgeons (LE: surgical trainees and fellows), performed 3 laparoscopic and robotic training-box-based tasks. This entire set of tasks was performed twice. Results Compared with LN, LEs showed significantly better performances in all laparoscopic tasks and in robotic task 3 during the 2 trials. Within the LN group, better performances were shown in all robotic tasks compared with the same laparoscopic tasks. However, in the LE group, compared with the same laparoscopic tasks, significantly better performance was seen only in robotic task 1. When we compared the 2 sets of trials, in the second trial, LN showed better performances in laparoscopic task 2 and robotic task 3; LE showed significantly better performance only in robotic task 3. Conclusion Robotic surgery had better performance than laparoscopic surgery in all tasks during the two trials. However, these results were more noticeable for LN. These results suggest that robotic surgery can be easily learned without laparoscopic experience because of its technical advantages. However, further experimental trials are needed to investigate the advantages of robotic surgery in more detail. PMID:24851216

Menopausal hormone therapy and risk of cholecystectomy: a prospective study based on the French E3N cohort  

PubMed Central

Background: Studies in the United States and the United Kingdom have reported an increased risk of cholecystectomy among women exposed to menopausal hormone therapy, but with substantial heterogeneity between types of hormone treatments. We evaluated the risk of cholecystectomy associated with different regimens of menopausal hormone therapy in a large prospective cohort study. Methods: Between 1992 and 2008, 70 928 menopausal women from the French E3N study cohort were sent questionnaires assessing their use of menopausal hormone therapy, medical history and lifestyle characteristics. The primary outcome was cholecystectomy. We analyzed the risk of cholecystectomy associated with use of menopausal hormone therapy using Cox proportional models, with age as time-scale. Results: During follow-up, 45 984 (64.8%) of the participants were exposed to menopausal hormone therapy, and 2819 cholecystectomies were recorded. The use of menopausal hormone therapy was associated with an increased risk of cholecystectomy (adjusted hazard ratio [HR] 1.10, 95% confidence interval [CI] 1.01–1.20) compared with women who were not exposed to menopausal hormone therapy. The association was restricted to unopposed oral estrogen therapy (adjusted HR 1.38, 95% CI 1.14–1.67). Over 5 years, about 1 cholecystectomy in excess would be expected in every 150 women using oral estrogen therapy without progestogens, compared with women not exposed to menopausal hormone therapy. Interpretation: The risk of cholecystectomy was increased among women exposed to oral estrogen menopausal hormone therapy, especially oral regimens without a progestagen. Complicated gallstone disease should be added to the list of potential adverse events to be considered when balancing the benefits and risks associated with menopausal hormone therapy. PMID:23509128

Laparoscopic Management of Complex Crohn's Disease  

PubMed Central

Background: Although the technical feasibility of laparoscopic management of Crohn's disease has been described, it remains of limited perceived usefulness in the management of surgically complex Crohn's. Successful management of such disease by using minimal access techniques is described. Patients and Methods: Seventeen patients underwent laparoscopically assisted procedures to address clinically complex disease. Goals of the laparoscopic phase included mobilization of pertinent structures, localization of disease, and precise selection of incision location. Clinical situations encountered included fistulas, multiple-or long-segment disease, abscesses, and reoperative management. Results: Conversion to completely open procedures was not necessary in any case. Operative time was longer in complex Crohn's disease than in concurrently managed patients who underwent laparoscopic ileal/cecal resection for limited disease (244±18 vs 127±5 minutes, P<0.05). Management of long-segment or multi-segment disease was associated with the longest operative times (292±36 minutes). Length of hospitalization was also longer than after management of limited ileal disease (7.1±1.4 vs 4.5±0.4 days). Major complications occurred in 18%. Conclusions: Laparoscopic techniques can be applied to complex Crohn's disease with effective disease management. In patients who may require multiple procedures, maintenance of abdominal wall integrity should be of significant value. PMID:12856841

Laparoscopic Resection of Retroperitoneal Neural Tumors  

PubMed Central

Purpose Retroperitoneal neural tumor (RNT) is rarely excised laparoscopically, and the laparoscopic management of RNT remains controversial. We herein report 4 cases of laparoscopic excision of RNT that resulted in diverse clinical outcomes. Patients and Methods Between August 2005 and January 2011, we performed laparoscopic excision of RNT in 4 patients. The mean tumor size was 4.5 cm. The mean operative time was 297 minutes and the mean amount of blood loss was 55 ml. The surgeries were uneventful, with no operative complications or evidence of intra-abdominal bleeding. However, 2 patients required reoperation for delayed hemorrhage and urinoma formation, respectively. Results The postoperative pathological diagnoses were schwannoma in 3 patients and ganglioneuroblastoma in 1 patient. All patients were well with no signs of peripheral neuropathy or radiculopathy, and CT and/or 18F-FDG PET/CT performed during follow-up indicated no evidence of disease. Conclusions Obtaining extensive preoperative knowledge of the source neural and vascular anatomy of the tumor is important for the surgical planning of laparoscopic resection of RNT. When a great deal of care is taken to divide the tumor and the source nerves and vital vessels, safe execution of RNT can be achieved for minimal postoperative mortality and morbidity. PMID:24917756

Total Laparoscopic Hysterectomy for Large Uterus  

PubMed Central

Aim: In this review, we assessed the feasibility of total laparoscopic hysterectomy (TLH) in cases of very large uteri weighing more than 500 grams. We have analyzed whether it is possible for an experienced laparoscopic surgeon to perform efficient total laparoscopic hysterectomy for large myomatous uteri regardless of the size, number and location of the myomas. Design: Retrospective review (Canadian Task Force Classification II-1) Setting: Dedicated high volume Gynecological laparoscopy centre. Patients: 173 women with symptomatic myomas who underwent total laparoscopic hysterectomy at our center. There were no exclusion criteria based on the size number or location of myomas. Intervention: TLH and modifications of performing the surgery by ligating the uterine arteries prior, myomectomy followed by hysterectomy, direct morcellation after uterine artery ligation. Results: 72% of patients had previous normal vaginal delivery and 28% had previous cesarean section. Average clinical size of the uterus was 18 weeks (10, 32). The average weight of the specimen was 700 grams (500, 2240). The average duration of surgery was 107 min (40, 300) and the average blood loss was 228 ml (10, 3200). Conclusion: Total laparoscopic hysterectomy is a technically feasible procedure. It can be performed by experienced surgeons for large uteri regardless of the size, number or location of the myomas.

Bimanual haptic workstation for laparoscopic surgery simulation.  

PubMed

Realistic laparoscopic surgical simulators will require real-time graphic imaging and tactile feedback. Our research objective is to develop a cost-effective haptic workstation for the simulation of laparoscopic procedures for training and treatment planning. The physical station consists of a custom-built frame into which laparoscopic trocars and surgical tools may be attached/inserted and which are continuously adjustable to various positions and orientations to simulate multiple laparoscopic surgical approaches. Instruments inserted through the trocars are attached to end effectors of two haptic devices and interfaced to a high speed PC with fast graphics capability. The haptic device transduces 3D motion of the two manually operated surgical instruments into slave maneuvers in virtual space. The slave instrument tips probe the simulated organ. Simulations currently in progress include: 1) Surface-only renderings, deformation, and haptic interactions with elements in the gall gladder surgical field; 2) Voxel-based simulations of the bulk manipulation of tissue; 3) laparoscopic herniorrhaphy. This system provides force feed-forward from the grasped tools to the contact tissue in virtual space, with deformation of the tissue by the virtual probe, and force feedback from the deformed tissue to the operator's hands.

Visual search behaviour during laparoscopic cadaveric procedures  

NASA Astrophysics Data System (ADS)

Laparoscopic surgery provides a very complex example of medical image interpretation. The task entails: visually examining a display that portrays the laparoscopic procedure from a varying viewpoint; eye-hand coordination; complex 3D interpretation of the 2D display imagery; efficient and safe usage of appropriate surgical tools, as well as other factors. Training in laparoscopic surgery typically entails practice using surgical simulators. Another approach is to use cadavers. Viewing previously recorded laparoscopic operations is also a viable additional approach and to examine this a study was undertaken to determine what differences exist between where surgeons look during actual operations and where they look when simply viewing the same pre-recorded operations. It was hypothesised that there would be differences related to the different experimental conditions; however the relative nature of such differences was unknown. The visual search behaviour of two experienced surgeons was recorded as they performed three types of laparoscopic operations on a cadaver. The operations were also digitally recorded. Subsequently they viewed the recording of their operations, again whilst their eye movements were monitored. Differences were found in various eye movement parameters when the two surgeons performed the operations and where they looked when they simply watched the recordings of the operations. It is argued that this reflects the different perceptual motor skills pertinent to the different situations. The relevance of this for surgical training is explored.

Complications of diverticular disease: surgical laparoscopic treatment  

PubMed Central

Surgical treatment of complicated colonic diverticular disease is still debatable. The aim of our study was to evaluate the outcome of laparoscopic colon resection in patients with diverticulitis and with complications like colon-vescical fistula, peridiverticular abscess, perforation or stricture. All patients underwent laparoscopic colectomy within 8 years period. Main data recorded were age, sex, return of bowel function, operation time, duration of hospital stay, ASA score, body mass index (BMI), early and late complications. During the study period, 33 colon resections were performed for diverticulitis and complications of diverticulitis. We performed 5 associated procedures. We had 2 postoperative complications; 1 of these required a redo operation with laparotomy for anastomotic leak and 3 patients required conversion from laparoscopic to open colectomy. The most common reasons for conversion were related to the inflammatory process with a severe adhesion syndrome. Mean operative time was 229 minutes, and average postoperative hospital stay was 9,8 days. Laparoscopic surgery for complications of diverticular disease is safe, effective and feasible. Laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis in our institution. PMID:24979103

Fluidic lens laparoscopic zoom camera for minimally invasive surgery  

NASA Astrophysics Data System (ADS)

This work reports a miniaturized laparoscopic zoom camera that can significantly improve vision for minimally invasive surgery (MIS), also known as laparoscopic surgery. The laparoscopic zoom camera contains bioinspired fluidic lenses that can change curvature and focal length in a manner similar to the crystalline lenses in human eyes. The traditional laparoscope is long, rigid, and made of fixed glass lenses with a fixed field of view. The constricted vision of a laparoscope is often an inconvenience and plays a role in many surgical injuries. To further advance MIS technology, we developed a new type of laparoscopic camera that has a total length of less than 17 mm, greater than 4× optical zoom, and 100 times higher sensitivity than today's laparoscope allowing it to work under illumination as low as 300 lux. All these unique features are enabled by the technology of bioinspired fluidic lenses having a dynamic range over 100 diopters and being convertible between a convex and concave shape.

Recurrence of uterine tissue residues after laparoscopic hysterectomy or myomectomy.  

PubMed Central

Objective: To report a new complication after laparoscopic surgery i.e recurrence of endometrium and leiomyoma fragments from uterine tissue residues after laparoscopic hysterectomy or laparoscopic myomectomy. Methods: This study was carried out on three patients with the recurrence of endometrium or leiomyoma fragments from tissue residues after laparoscopic hysterectomy or laparoscopic myomectomy in the First Affiliated Hospital, Yangtze University, China. We also explored the possible reasons and corresponding preventative strategies. Results: Small residues of endometrium and leiomyoma fragments could implant into normal tissue anywhere in the peritoneal cavity after laparoscopic myomectomy or laparoscopic hysterectomy. Conclusion: These cases emphasize the importance of removing every single fragment to prevent the recurrence of endometrium and leiomyoma from tissue residues. PMID:25225541

Laparoscopic resection of a retroperitoneal pelvic schwannoma  

PubMed Central

Schwannomas are rarely located in the pelvis. A 54-year-old woman was found incidentally to have a tumor in the abdomen. Abdominal computed tomography and magnetic resonance imaging revealed a well-defined, heterogeneous tumor, 5 cm in diameter, in the pelvic cavity. With a diagnosis of a mesenteric tumor, a laparoscopic procedure was performed. Intra-operatively, an elastic tumor was identified in the pelvis adjacent to the right internal iliac vein and ureter. The tumor was dissected free from adjacent structures using Liga-Sure and blunt maneuvers. A complete laparoscopic excision was performed. Histopathological examination revealed a benign schwannoma. The patient had an uneventful post-operative course, and was discharged on the fourth post-operative day. Laparoscopic treatment is useful and feasible for retroperitoneal pelvic schwannoma, with minimal invasiveness and an early post-operative recovery. Thus, this procedure may be the first-choice surgical procedure for retroperitoneal pelvic schwannomas. PMID:24876325

[Robotics-assisted laparoscopic colorectal resection].  

PubMed

The value of laparoscopic surgery for rectal cancer is still controversially discussed. Robotics offers the opportunity to leave the limitations of conventional laparoscopy behind us. The three-dimensional visualization and the superior dexterity by wristed instruments should be particularly helpful in complex laparoscopic procedures in confined spaces such as the small pelvis. Colorectal resections using the Da Vinci® system are well established and becoming increasingly more standard procedures. Nerve-sparing total mesorectal excision in patients with rectal cancer, total mesocolic excision in patients with right-sided colon cancer and rectopexy in patients with pelvic floor insufficiency are the most promising indications. The prospective randomized ROLARR study has been evaluating the application of the Da Vinci® system in laparoscopic rectal cancer surgery since 2011. Besides the currently available clinical data the perioperative and intraoperative logistics and strategy will be presented in detail. PMID:23942962

Diagnostic laparoscopic biopsy for intraabdominal tumors.  

PubMed

Improvements in imaging technology have resulted in an increase in the incidental detection of intraabdominal tumors. Diagnostic computed tomography (CT)- and ultrasound (US)-guided biopsy, while minimally invasive, often provides specimens that are insufficient for histological evaluation. Moreover, it can be difficult to perform because the location and size of the tumor. In such cases, laparoscopic biopsy is useful because it is less invasive than laparotomy, but more reliable than imaging-guided biopsy, to obtain a sufficient specimen, regardless of the location and size of the tumor. We report a series of seven patients who underwent laparoscopic biopsy of intraabdominal tumors of unknown origin. There were no cases of conversion to laparotomy and all patients were able to resume oral intake on postoperative day 1. There were no intraoperative or postoperative complications. Thus, laparoscopic biopsy for a tumor of unknown origin is useful and minimally invasive. PMID:25212568

Circumstance of endoscopic and laparoscopic treatments for gastric cancer in Japan: A review of epidemiological studies using a national administrative database  

PubMed Central

Currently, endoscopic submucosal dissection (ESD) and laparoscopic gastrectomy (LG) have become widely accepted and increasingly play important roles in the treatment of gastric cancer. Data from an administrative database associated with the diagnosis procedure combination (DPC) system have revealed some circumstances of ESD and LG in Japan. Some studies demonstrated that medical costs or length of stay of patients receiving ESD for gastric cancer had become significantly reduced while length of hospitalization and costs were significantly increased in older patients. With respect to LG, some recent reports have shown that this has been a cost-beneficial treatment for patients compared with open gastrectomy while simultaneous LG and cholecystectomy is a safe procedure for patients with both gastric cancer and gallbladder stones. These epidemiological studies using the administrative database in the DPC system closely reflect clinical circumstances of endoscopic and surgical treatment for gastric cancer in Japan. However, DPC database does not contain detailed clinical data such as histological types and lesion size of gastric cancer. The link between the DPC database and another detailed clinical database may be vital for future research into endoscopic and laparoscopic treatments for gastric cancer. PMID:25685268

We define ovarian retention pathology as the complications (cystic, degenerative, adhesions, endometriosis, pain, etc.) attributed to ovaries deliberately retained at the time of hysterectomy. We established a protocol for laparoscopy in these women. During 14 laparoscopic procedures for ovarian retention pathology, only one intraoperative complication occurred, a small bowel injury requiring minilaparotomy. One woman required repeat surgery for ovarian remnant syndrome. Published experience with laparotomy suggests that significant injuries to or resections of bowel, bladder, or ureters can occur, but the limited experience with laparoscopic surgery has not shown significant complications.

Laparoscopic repair of ventral / incisional hernias  

PubMed Central

Despite its significant prevalence, there is little in the way of evidence-based guidelines regarding the timing and method of repair of incisional hernias. To add to the above is the formidable rate of recurrence that has been seen with conventional tissue repairs of these hernias. With introduction of different prosthetic materials and laparoscopic technique, it was hoped that an improvement in the recurrence and complication rates would be realized. The increasing application of the laparoscopic technique across the world indicates that these goals might indeed be achieved. PMID:21187995

Oncologic implications of laparoscopic and open surgery.  

PubMed

Although instrumental manipulation and mechanical tumor cell spillage seem to play the major role in port-site metastases from laparoscopic cancer surgery, minimally invasive procedures are used more and more in the resection of malignancies. However, port-site metastases also have been reported after resection of colon cancer in International Union Against Cancer (UICC) stage I [2, 14]. Therefore, changes in the peritoneal environment during laparoscopy also might influence intra- and extraperitoneal tumor growth during laparoscopy and pneumoperitoneum. Different results of experimental studies presented at the Third International Conference for Laparoscopic Surgery are analyzed and discussed. PMID:11928024

Laparoscopic Hysterectomy with Automatic Stapling Devices  

PubMed Central

Purpose: To evaluate outcomes including operating time, blood loss, length of stay (LOS), return to work and complications of laparoscopic hysterectomy performed with automatic stapling devices. Methods: Between 6/11/91 and 11/23/95, 127 laparoscopic hysterectomies were performed with automatic stapling devices. On an average, 6 firings with the stapler were done per case. Postoperative telephone survey and retrospective review of records were done. Results: Data averages for operating time, blood loss, LOS and return to work, respectively, were 90 minutes, 190 cc's, 1.1 day and 2 weeks. Significant complications included delayed postoperative bleeding in 4 patients, all of which occurred within the first 35 cases. One was controlled laparoscopically and 3 others required exploratory laparotomies. Since certain precautionary measures as described were taken, hemorrhagic complications were eliminated. Conclusions: Laparoscopic hysterectomy can be performed safely and effectively with automatic stapling devices in properly selected patients. A potential hazard inherent with this technique includes intraoperative and postoperative bleeding from the staple lines, the incidence of which can be minimized by taking certain precautionary measures such as the use of white cartridges only and bipolar desiccation of staple lines when indicated.

Laparoscopic surgery for colorectal cancer in China: an overview  

PubMed Central

Since its introduction into China in 2001, laparoscopic techniques have been extensively used for the surgical management of colorectal cancer during the last two decades in China. Like all the pioneers of the technique, Chinese gastrointestinal surgeons claim that laparoscopic surgery for colorectal cancer led to faster recovery, shorter hospital stay and more rapid return to daily activities respect to open surgery while offering the same functional and oncological results. There has been booming interest in laparoscopic surgery for colorectal cancer since 2006 in China. The last decade has witnessed national growth in the application of laparoscopic surgery for colorectal cancer and yielded a significant amount of scientific data to support its clinical merits and advantages. However, few prospective randomized controlled trials have investigated the benefits of laparoscopic surgery for colorectal cancer in China. In this article, we make an overview of the current data and state of the art of laparoscopic surgery for colorectal cancer in China. PMID:25663960

Results of Laparoscopic Versus Open Abdominal and Incisional Hernia Repair  

PubMed Central

Background: Incisional hernia is a frequent complication of abdominal surgery. The object of this study was to confirm the safety, efficacy, and feasibility of laparoscopic treatment of abdominal wall defects. Methods: Fifty consecutive laparoscopic abdominal and incisional hernia repairs from September 2001 to May 2003 were compared with 50 open anterior repairs. Results: The 2 groups were not different for age, body mass index, or American Society of Anaesthesiologists scores. Mean operative time was 59 minutes for the laparoscopic group, 164.5 minutes for the open group. Mean hernia diameter was 10.6 cm for the laparoscopic group, 10.5 cm for the open group. Mean length of stay was 2.1 days for the laparoscopic group, 8.1 days for the open group. Complications occurred in 16% of the laparoscopic and 50% of open group. Median follow-up was 9.0 months for the laparoscopic group, 24.5 months for the open group. Recurrence rates were 2% for laparoscopic group and 0% for the open group. Conclusion: Results for laparoscopic abdominal and incisional hernia repair seem to be superior to results for open repair in terms of operative time, length of stay, wound infection, major complications, and overall hospital reimbursement.

We present a case of parasitic myoma complaining of abdominal pain, constipation, dyspareunia and dysmenorrhea 4 years after laparoscopic myomectomy. We performed laparoscopic myomectomy for multiple parasitic myomas. Three myomas were very firmly attached to bowel and mesentery. Parasitic myoma after laparoscopic surgery is very rare condition there are almost 35 cases in the literature. It is related with variable symptoms or can be asymptomatic. Laparoscopic surgeons should be aware of this situation, and further investigation should be made in case of suspicion. Surgery for parasitic myomas can be difficult in case of bowel and mesentery involvement and patient should be informed about the extensive surgery. PMID:25336821

Laparoscopic Surgery for Kidney Orthotopic Transplant in the Pig Model  

PubMed Central

Background and Objectives: Laparoscopic surgery has rapidly expanded in surgical practice with well-accepted benefits of minimal incision, less analgesia, better cosmetics, and quick recovery. The surgical technique for kidney transplantation has remained unchanged since the first successful kidney transplant in the 1950s. Over the past decade, there were only a few case reports of kidney transplantation by laparoscopic or robotic surgery. Therefore, the aim of this study is to develop a laparoscopic technique for kidney transplantation at the region of the native kidney. Methods: After initial development of the laparoscopic technique for kidney transplant in cadaveric pigs, 5 live pigs (Sus scrofa, weighing 45–50 kg) underwent laparoscopic kidney transplant under general anesthesia. First, laparoscopic donor nephrectomy was performed, and then the kidney was perfused and preserved with cold Ross solution. The orthotopic auto-transplant was subsequently performed using the laparoscopic technique. The blood flow of the kidney graft was assessed using Doppler ultrasonography, and urine output was monitored. Results: The laparoscopic kidney transplant was successful in 4 live pigs. Immediate urine output was observed in 3 pigs. The blood flow in the kidney was adequate, as determined using Doppler ultrasonography. Conclusion: It has been shown that laparoscopic kidney orthotopic transplant is feasible and safe in the pig model. Immediate kidney graft function can be achieved. A further study will be considered to identify the potential surgical morbidity and mortality after recovery in a pig model before translating the technique to clinical human kidney transplantation.

During the period of 13 months, the authors have operated on seven patients with perforated gastroduodenal ulcers. All surgeries were completely performed by the laparoscopic method. The laparoscopic suture of perforated ulcers was performed with lavage and only in one case it involved omentoplasty. The healing process was free of any complications in all patients. The advantage of laparoscopic operations of perforated ulcers resides in fast convalescence and in the fast restoration of working abilities. This method is appropriate in cases when the surgeon performing laparoscopic surgeries has sufficient experience in coincidence with the treatment of perforated ulcers. PMID:9721467

Comparison of open and laparoscopic live donor nephrectomy.  

PubMed Central

OBJECTIVE: This study compares an initial group of patients undergoing laparoscopic live donor nephrectomy to a group of patients undergoing open donor nephrectomy to assess the efficacy, morbidity, and patient recovery after the laparoscopic technique. SUMMARY BACKGROUND DATA: Recent data have shown the technical feasibility of harvesting live renal allografts using a laparoscopic approach. However, comparison of donor recovery, morbidity, and short-term graft function to open donor nephrectomy has not been performed previously. METHODS: An initial series of patients undergoing laparoscopic live donor nephrectomy were compared to historic control subjects undergoing open donor nephrectomy. The groups were matched for age, gender, race, and comorbidity. Graft function, intraoperative variables, and clinical outcome of the two groups were compared. RESULTS: Laparoscopic donor nephrectomy was attempted in 70 patients and completed successfully in 94% of cases. Graft survival was 97% versus 98% (p = 0.6191), and immediate graft function occurred in 97% versus 100% in the laparoscopic and open groups, respectively (p = 0.4961). Blood loss, length of stay, parenteral narcotic requirements, resumption of diet, and return to normal activity were significantly less in the laparoscopic group. Mean warm ischemia time was 3 minutes after laparoscopic harvest. Morbidity was 14% in the laparoscopic group and 35% in the open group. There was no mortality in either group. CONCLUSIONS: Laparoscopic live donor nephrectomy can be performed with morbidity and mortality comparable to open donor nephrectomy, with substantial improvements in patient recovery after the laparoscopic approach. Initial graft survival and function rates are equal to those of open donor nephrectomy, but longer follow-up is necessary to confirm these observations. PMID:9351716

Laparoscopic resection of a giant exophytic liver haemangioma with the laparoscopic Habib 4× radiofrequency device.  

PubMed

Haemangiomas are the most common solitary benign neoplasm of the liver with an incidence ranging from 5% to 20%. Although usually small and asymptomatic, they may reach considerable proportions and rarely give rise to life-threatening complications. Surgical intervention is required for incapacitating symptoms, established complications, and diagnostic uncertainty. The resection of haemangiomas demands meticulous surgical technique, owing to their high vascularity and the concomitant risk of intra-operative haemorrhage. Laparoscopic resection of giant haemangiomas is even more challenging, and has only been reported twice. We here report the case of a giant 10 cm liver haemangioma which was successfully resected laparoscopically using the laparoscopic HabibTM 4×, a bipolar radiofrequency device, without clamping major vessels and with minimal blood loss. Transfusion of blood or blood products was not required. The patient had an uneventful recovery and was asymptomatic at 7-mo follow-up. PMID:23293733

Laparoscopic hernia repair--the best option?  

PubMed

For 100 years the Bassini-type repair for inguinal hernia was the standard method. The Lichtenstein "tension free" mesh repair replaced it on the grounds of much lower recurrence rates, < 5% vs approximately 15%. However, open procedures all have significant long-term discomfort rates of up to 53%. Laparoscopic repair has become a genuine option in the last 15 years and offers low recurrence (< 1%) and minimal long-term discomfort. However, it has not been widely taken up. There is a common misconception that it takes longer to perform, has more complications and is much more expensive. None of these caveats stand up under objective scrutiny. It is time that laparoscopic repair became the method of choice for most elective inguinal hernia repairs. PMID:18557141

Single Incision Laparoscopic Ventral Hernia Repair  

PubMed Central

Background and Objectives: Laparoscopic ventral hernia repair (LVH) requires several skin incisions for trocar placement. We have developed a single incision approach to LVH repair. The technique was introduced in clinical practice to any consenting patients who were candidates for a standard multi-port laparoscopic hernia repair. A consecutive series of patients was then followed to evaluate feasibility. Methods: Over an 8-month period, 14 patients (9 females, 5 males) underwent LVH repair by an academic surgeon. One of 2 access methods was used in each patient through a single 1.5-cm to 2-cm skin incision. One technique utilized two 5-mm ports with a temporarily placed 11-mm port for mesh insertion. The second technique utilized the SILS port (Covidien, Norwalk, CT). Standard or roticulating laparoscopic instruments were used with both techniques. Results: Range (mean) BMI: 23 to 59 (38), Age: 26 to 73 years (53), Duration: 37 to 87 minutes (57), Defect size: 1cm to 8cm (2), 3 with Swiss-cheese defect hernias. The procedure was successfully performed in all patients. No conversions to a multiple-port approach or to an open procedure were necessary. There were no mortalities, major complications, or recurrences during the mean follow-up period of 4 weeks. Conclusion: Single incision ventral hernia repair is technically feasible, effective, and reproducible. The technique is easy to master, and safe for any patient who is a candidate for laparoscopic ventral hernia repair. Further data collection with long-term follow-up will be needed to ensure equivalent outcomes. There will be demand for this approach by patients for cosmetic reasons, and it may serve as a bridge to natural orifice techniques. PMID:21902968

Postoperative ascites is a very rare complication of laparoscopic surgery. Significant iatrogenic injuries to the bowel, the urinary tract, and the lymphatic system should be excluded promptly to avoid devastating results for the patient. In some cases, in spite of investigating patients extensively, no definitive causative factor for the accumulation of fluid can be identified. In such cases, idiopathic allergic or inflammatory reaction of the peritoneum may be responsible for the development of ascites.

Laparoscopic fundoplication for gastroesophageal reflux disease.  

PubMed

Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of gastric contents into the esophagus leads to troublesome symptoms and/or complications. Heartburn is the cardinal symptom, often associated with regurgitation. In patients with endoscopy-negative heartburn refractory to proton pump inhibitor (PPI) therapy and when the diagnosis of GERD is in question, direct reflux testing by impedance-pH monitoring is warranted. Laparoscopic fundoplication is the standard surgical treatment for GERD. It is highly effective in curing GERD with a 80% success rate at 20-year follow-up. The Nissen fundoplication, consisting of a total (360°) wrap, is the most commonly performed antireflux operation. To reduce postoperative dysphagia and gas bloating, partial fundoplications are also used, including the posterior (Toupet) fundoplication, and the anterior (Dor) fundoplication. Currently, there is consensus to advise laparoscopic fundoplication in PPI-responsive GERD only for those patients who develop untoward side-effects or complications from PPI therapy. PPI resistance is the real challenge in GERD. There is consensus that carefully selected GERD patients refractory to PPI therapy are eligible for laparoscopic fundoplication, provided that objective evidence of reflux as the cause of ongoing symptoms has been obtained. For this purpose, impedance-pH monitoring is regarded as the diagnostic gold standard. PMID:25339814

Laparoscopic Repair of Incidentally Found Spigelian Hernia  

PubMed Central

Background and Objectives: A Spigelian hernia is a rare type of hernia that occurs through a defect in the anterior abdominal wall adjacent to the linea semilunaris. Estimation of its incidence has been reported as 0.12% of all abdominal wall hernias. Traditionally, the method of repair has been an open approach. Herein, we discuss a series of laparoscopic repairs. Methods: Case series and review of the literature. Cases: Three patients are presented. All were evaluated and taken to surgery initially for a different disease process, and all were incidentally found to have a spigelian hernia. These patients underwent laparoscopic repair of their hernias; 2 were repaired intraperitoneally and one was repaired totally extraperitoneally. Two patients initially underwent a mesh repair, while the third had an attempted primary repair. Conclusions: There is evidence that supports the use of laparoscopy for both diagnosis and repair of spigelian hernias. There are also reports of successful repairs both primarily and with mesh. In our experience with the preceding 3 patients, we found that laparoscopic repair of incidentally discovered spigelian hernias is a viable option, and we also found that implantation of mesh, when possible, resulted in satisfactory results and no recurrence.

Multiresolution foveated laparoscope with high resolvability.  

PubMed

A key limitation of the state-of-the-art laparoscopes for minimally invasive surgery is the tradeoff between the field of view and spatial resolution in a single-view camera system. As such, surgical procedures are usually performed at a zoomed-in view, which limits the surgeon's ability to see much outside the immediate focus of interest and causes a situational awareness challenge. We proposed a multiresolution foveated laparoscope (MRFL) aiming to address this limitation. The MRFL is able to simultaneously capture wide-angle overview and high-resolution images in real time; it can scan and engage the high-resolution images to any subregion of the entire surgical field in analogy to the fovea of human eye. The MRFL is able to render equivalently 10 million pixel resolution with a low data bandwidth requirement. The system has a large working distance (WD) from 80 to 180 mm. The spatial resolvability is about 45 ?m in the object space at an 80 mm WD, while the resolvability of a conventional laparoscope is about 250 ?m at a typically 50 mm surgical distance.

Iatrogenic diaphragmatic hernia due to laparoscopic gastric banding  

Microsoft Academic Search

A patient developed a huge diaphragmatic hernia following laparoscopic gastric banding. Almost the entire stomach was incarcerated within the left chest. Segmental necrosis of the greater curvature of the stomach necessitated partial gastrectomy. The postoperative course was uneventful. The etiology, diagnosis and treatment of this previously undescribed complication of laparoscopic gastric banding are addressed in relation to the present case.

Effect of laparoscopic abdominal surgery on splanchnic circulation: Historical developments  

PubMed Central

With the developments in medical technology and increased surgical experience, advanced laparoscopic surgical procedures are performed successfully. Laparoscopic abdominal surgery is one of the best examples of advanced laparoscopic surgery (LS). Today, laparoscopic abdominal surgery in general surgery clinics is the basis of all abdominal surgical interventions. Laparoscopic abdominal surgery is associated with systemic and splanchnic hemodynamic alterations. Inadequate splanchnic perfusion in critically ill patients is associated with increased morbidity and mortality. The underlying pathophysiological mechanisms are still not well understood. With experience and with an increase in the number and diversity of the resulting data, the pathophysiology of laparoscopic abdominal surgery is now better understood. The normal physiology and pathophysiology of local and systemic effects of laparoscopic abdominal surgery is extremely important for safe and effective LS. Future research projects should focus on the interplay between the physiological regulatory mechanisms in the splanchnic circulation (SC), organs, and diseases. In this review, we discuss the effects of laparoscopic abdominal surgery on the SC. PMID:25561784
