Total quality management in laparoscopic cholecystectomy. Quality of care and quality perception in ambulatory laparoscopic cholecystectomy.

OBJECTIVE: Analysis of acceptance and perception of quality in patients undergoing ambulatory laparoscopic cholecystectomy. PATIENTS: 84 consecutive patients undergoing elective laparoscopic cholecystectomy within SVS (Servei Valencia de Salut) through a special plan for waiting lists. METHODS: A prospective analysis of related variables with quality perception evaluated by a specialized nurse with no interaction with the surgical team. RESULTS: Ambulatory acceptance, 80 percent; return to work or daily activities at 72 hours after surgery, 40 percent. Extra need of medical attention was as follows: emergency general practitioner 2.7 percent, emergency room attention in 1.3 percent, extra telephone interview with the surgeon 6.0 percent. Global estimation of the procedure was very good or good by 94.7 percent. CONCLUSIONS: High acceptance rate, high quality perception. Up to 20 percent of patients would change from ambulatory to traditional surgery, possibly due to cultural factors.

[Percutaneous electrogastrography in the perioperative period in laparoscopic and classical cholecystectomy and in laparoscopic nonadjustable gastric banding].

Percutaneous electrogastrography (EGG) is a non-invasive measuring method of gastric myoelectrical activity. We measured myoelectrical activity patients after laparoscopic cholecystectomy (16 patients), after laparotomic cholecystectomy (9 patients) and after gastric bandage (14 patients). We used a Microdigitrapper (Medtronic) and data were analysed with a spectral analysis and Fournier's transformation. We measured 24 hours and 5 hours before operation procedure and 24 and 48 hours after operation. After operative procedure we compared results with healthy voluntaries. Bradygastria was found in most frequent cases in early postoperative period. Physiologic conditions were renewed in laparoscopic operative procedure in first day, after laparotomic operation in second day after operation.

[Laparoscopic treatment of bile leakage from the Luschka duct after laparoscopic cholecystectomy].

The possible reasons for bile leakage following laparoscopic cholecystectomy are the injury of the common bile duct, the insufficient treatment of cystic duct (non competent or non closing, or spontaneously removing clip, stumpnecrosis due to electrocoagulation near to clipp, rupture adjacent to the clipp) or the opening of an aberrant bile duct. The latter often may occur in case of the anatomic variation described by Hubert von Luschka (1820-1875) a German anatomist as the duct named after Luschka. In a favorable case the accessory bile duct closes by itself, but occasionally developing biloma and/or biliary peritonitis need to be operated on. The authors write about the case of a 52 years old female patient, who underwent laparoscopic cholecystectomy, and 3 days later the complication was averted through the application of relaparoscopy with intracorporal suture. In connection with this case the authors acquaint the readers with the biography, the academic carrier of Hubert von Luschka, and the literature related to Luschka duct is surveyed.

Positive intraoperative cholangiography during laparoscopic cholecystectomy: is laparoscopic common bile duct exploration necessary?

The treatment of choledocholithiasis discovered incidentally during laparoscopic cholecystectomy is not yet standardized. Options include laparoscopic common bile duct exploration (LCBDE), postoperative endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy (ERCP-ES), and no intervention. We undertook a review of our case series to determine whether LCBDE is obligatory and which LCBDE method is unsuccessful. During the 6-year study period, 91 patients with choledocholithiasis were identified. Fifty-six patients (62%) underwent LCBDE. Thirteen (23%) of these 56 patients subsequently required ERCP. Balloon sweeping of the common bile duct failed in 10 of 21 patients (48% failure) compared to any other combination of techniques with a failure rate of 1/33 (3%; P < 0.001). Two patients did not undergo complete duct exploration because of technical problems. Thirty-five patients (38%) did not undergo LCBDE. Nine of these patients (26%) did not have ERCP-ES. None of the patients who underwent postoperative ERCP-ES required additional procedures or surgery. LCBDE can successfully treat common bile duct stones, with minimal to no morbidity, but is not mandatory for safely treating choledocholithiasis. Additionally, advanced techniques for clearing the common bile duct are more successful. Surgeons should be proficient at performing these techniques.

The physiology of laparoscopic surgery: pulmonary function after laparoscopic cholecystectomy.

Changes in pulmonary function were studied via standard spirometry in 30 patients after laparoscopic cholecystectomy (LC) and compared with those in nine patients after traditional open cholecystectomy (OC). Studies performed presurgery and the morning after surgery included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and forced expiratory flow (FEF25%-75%). Age (43.9 +/- 2.6 years for LC and 42.3 +/- 3.2 for OC), sex, reasons for cholecystectomy, and smoking history were similar in both groups. The mean FVC decreased 23% after LC (3.57 +/- 0.18 L presurgery, range 0.56-5.62, versus 2.68 +/- 0.17 postsurgery, range 0.65-5.14) and 35.2% after OC (mean 3.52 +/- 0.29 presurgery, range 2.38-4.99, versus 2.24 +/- 0.24, range 1.23-3.49 postsurgery). FEV1 showed similar changes, with LC decreasing pulmonary function by 24.3% (2.76 +/- 0.14 L presurgery versus 2.01 +/- 0.12 postsurgery) compared with a 36.2% reduction in FEV1 after OC (2.86 +/- 0.29 L presurgery versus 1.81 +/- 0.21 L postsurgery). Forced expiratory flow decreased by 24.3% after LC and 40% after OC. Laparoscopic cholecystectomy provides less decrement in pulmonary function than traditional open cholecystectomy.

Simultaneous laparoscopic cholecystectomy and laparoscopically assisted vaginal hysteroadnexectomy.

As a consequence of the wide applications of operative laparoscopy and thoracoscopy, simultaneous surgical procedures have been carried out endoscopically. We report a 51-year-old woman treated by simultaneous laparoscopic cholecystectomy and celioscopically assisted vaginal hysteroadnexectomy for hydropic calculous gallbladder, uterine myomas, and bilateral ovarian policystosis. These procedures were carried out using six abdominal trocar sites, and the gallbladder was removed through the colpotomic access. The patient had an uncomplicated postoperative course and was discharged on postoperative day 5. In our opinion, the multidisciplinary laparoscopic approach, with the original technical solutions, represents an effective, minimally invasive method of treatment that gives new perspective about the indications and the treatment of similar cases.

Hand-assisted laparoscopic splenectomy vs conventional laparoscopic splenectomy in cases of splenomegaly.

HYPOTHESIS: Laparoscopic splenectomy (LS) is the procedure of choice for elective splenectomy. Splenomegaly may preclude safe mobilization and hilar control using conventional laparoscopic techniques. Hand-assisted LS (HALS) may offer the same benefits of minimally invasive surgery for splenomegaly while allowing safe manipulation and splenic dissection. DESIGN: A retrospective review of patients with splenomegaly undergoing conventional LS or HALS was performed. SETTING: Tertiary care referral center. PATIENTS: Hand-assisted LS was performed at the start of the operation for patients with splenomegaly; splenomegaly was determined by palpation of the splenic tip extending to the midline or the iliac crest, or by a craniocaudal splenic length of greater than 22 cm. Splenomegaly was defined as a splenic weight of greater than 700 g after morcellation. MAIN OUTCOME MEASURES: Patient demographic characteristics, operative indications, splenic weight after morcellation, morbidity, mortality, and clinical outcomes were evaluated. RESULTS: Forty-five patients with splenomegaly were identified: 31 underwent standard LS and 14 underwent HALS. The HALS group had significantly larger spleens than the conventional LS group (mean weight, 1516 vs 1031 g; P =.02). Mean operative time (177 vs 186 minutes; P =.89), estimated blood loss (602 vs 376 mL; P =.17), and length of hospital stay (5.4 vs 4.2 days; P =.24) and complication rates (5 [36%] of 14 vs 5 [16%] of 31; P =.70) were similar between the HALS and the standard LS groups. No perioperative mortality occurred. CONCLUSIONS: Hand-assisted LS is a safe and efficacious procedure for these extremely difficult cases. Hand-assisted LS provides the benefits of a minimally invasive approach in cases of splenomegaly.

Prospective multicenter study of the quality of oncologic resections in patients undergoing laparoscopic colorectal surgery for cancer. The Laparoscopic Colorectal Surgery Study Group.

PURPOSE: Laparoscopic colorectal surgery for cancer is currently under discussion. Results of large, randomized studies will not be available for a number of years yet. This study analyses the results of such resections in consecutive patients operated on by unselected surgeons. METHODS: A prospective, observational, multicenter study was initiated on August 1, 1995, in the German-speaking countries of Europe. One year after initiation of the study, findings are presented with respect to the quality of oncologic resections. RESULTS: Of 500 operations, 231 (46 percent) were performed for cancer, 167 (33 percent) with a curative intent. The most common curative resections were as follows: 63 anterior rectum resections (38 percent), 51 sigmoid resections (30 percent), and 27 abdominoperineal resections (16 percent). Segmental resections were performed in 20 patients (12 percent). Intraoperative tumor spillage was reported in 2 percent. Mean number of lymph nodes harvested was 13 (confidence interval, 5-95 percent; range, 11.5-14.6) and positive lymph nodes harvested was 2.2 (confidence interval, 5-95 percent; range, 0.9-3.4). Significant differences were noted between participating centers in terms of number of lymph nodes resected (P < 0.0001). Distal and proximal resection margins were tumor-free in every case. Lateral margins were tumor free when examined. In the case of 63 curative anterior resections, the mean distal resection margin was 39 (confidence interval, 5-95 percent; range, 33-45) mm, and in 8 of these resections, it was less than 20 min. Mean blood loss was 344 (confidence interval, 5-95 percent; 292-396) ml, and 21 percent of patients received blood transfusion. CONCLUSIONS: These data document that the average quality of laparoscopic colorectal procedures for cancer is satisfactory but differs among surgeons.

Emergency laparoscopic splenectomy for "wandering" (pelvic) spleen: case report and review of the literature on laparoscopic approach to splenic diseases.

Wandering spleen (WS) is a rare condition where the spleen, free from its ligaments, is allowed to move inside the abdomen predisposing the patient to life-threatening complications due to torsion of the vascular pedicle; splenic infarction, portal hypertension, bleeding and acute abdomen may occur. WS is rarely suspected at presentation since symptoms are usually not specific and definitive diagnosis is usually reached only by imaging technologies such as color flow ultrasonography and angio-spiral computer tomography. A 42-year-old woman was referred to our institute from the Emergency and Accident ward, complaining of a sudden onset of sharp abdominal pain together with nausea and vomiting. At examination a large, painful mass was present on the left middle-lower abdominal quadrant. A pelvic spleen was revealed at abdominal ultrasonography (US) and confirmed by abdominal CT. Emergency laparoscopy was carried out. The spleen was barely attached to the peritoneum of the anterior abdominal wall, covered by the greater omentum, the small bowel, and the transverse colon. Once mobilization of the spleen was concluded, the vascular pedicle appeared torted and thrombosed and laparoscopic splenectomy was performed. The patient was discharged on the 4th postoperative day with no complications. To date, only 5 cases of laparoscopic approach to WS have been reported. A review of the literature confirms that the reduction of postoperative stay, wound complications, and overall morbidity and a faster return to normal activity make laparoscopy the "gold standard" approach to the spleen as for treatment of many hematological disorders or more unusual splenic diseases.

Early U.S. outcomes of laparoscopic gastric bypass versus laparoscopic adjustable silicone gastric banding for morbid obesity.

Laparoscopic gastric bypass (LGBP) is the gold standard operation for long-term weight control in the United States. Laparoscopic adjustable silicone gastric banding (LASGB) is the preferred operative method for morbid obesity worldwide. Limited data are available comparing the two procedure in the United States. This study compares weight loss, complications, and early outcome of comorbidity resolution in patients who underwent LGBP versus LASGB. A review of prospectively collected data was performed on 392 patients undergoing primary LGBP (n = 232) and LASGB (n = 160) procedures between February 2001 and July 2004. Differences in percentage excess weight lost (%EWL) at 3, 6, 12, 18, and 24 months postop, improvement or resolution of comorbidities, and complications across procedure types were evaluated. Mean initial body mass index between groups was not significantly different (LGBP 47.2 vs LASGB 47.1, p < 0.53). There were significant differences in age, gender, and self-reported sweet-eating behavior between operative groups. There was a significantly greater %EWL in patients who underwent LGBP compared to patients of the LASGB groups 3, 6, 12, and 18 months after surgery. There were no significant differences in resolution or improvement of comorbidities between the groups. Although LGBP patients experienced more complications compared to LASGB patients (5.6 vs 4.3%, respectively; p < 0.56), this did not reach statistical significance. Early after surgery, LGBP patients lose more weight than LASGB patients but have similar improvements in comorbidities. Further follow-up is needed to determine the relative long-term efficacy of these procedures.

Laparoscopic adjustable gastric band versus laparoscopic Roux-en-Y gastric bypass: ends justify the means?

BACKGROUND: In the United States, the most frequently performed bariatric procedure is the Roux-en-Y gastric bypass (RYGB). Worldwide, the most common operation performed is the laparoscopic adjustable gastric band (LAGB). The expanding use of LAGB is probably driven by the encouraging data on its safety and effectiveness, in contrast to the disappointing morbidity and mortality rates reported for RYGB. The aim of this study was to evaluate the results of LAGB versus RYGB at a single institution. METHODS: Between November 2000 and July 2004, 590 bariatric procedures were performed. Of these, 120 patients (20%) had laparoscopic RYGB and 470 patients (80%) had LAGB. A retrospective review was performed. RESULTS: In the LAGB group, 376 patients (80%) were female, and the mean age was 41 years (range, 17-65). In the RYGB group, 110 patients (91%) were female, and the mean age was 41 years (range, 20-61). Preoperative body mass index was 47 +/- 8 and 46 +/- 5, respectively (p = not significant). Operative time and hospitalization were significantly shorter in LAGB patients (p < 0.001). Complications and the need for reoperation were comparable in both groups. Weight loss at 12, 18, 24, and 36 months for LAGB and RYGB was 39 +/- 21 versus 65 +/- 13, 39 +/- 20 versus 62 +/- 17, 45 +/- 25 versus 67 +/- 8, and 55 +/- 20 versus 63 +/- 9, respectively. CONCLUSIONS: The current study demonstrates that LAGB is a simpler, less invasive, and safer procedure than RYGB. Although mean percentage excess body weight loss (%EBWL) in RYGB patients increased rapidly during the first postoperative year, it remained nearly unchanged at 3 years. In contrast, in LAGB patients weight loss was slower but steady, achieving satisfactory %EBWL at 3 years. Therefore, we believe that LAGB should be considered the initial approach since it is safer than RYGB and is very effective at achieving weight loss.

Laparoscopic management of malignant ovarian cysts: a 78-case national survey. Part 1: Pre-operative and laparoscopic evaluation.

This paper reports a retrospective multi-institutional French survey carried out in 1992 to determine the incidence of laparoscopic management of malignant ovarian cysts. Of 5307 ovarian lesions treated endoscopically, 78 were malignant (1.47%) including 60 borderline tumors and 18 ovarian cancers. In 33% of cases preoperative diagnosis indicated that the tumor was benign. Preoperative findings were suspicious in 59%. Laparoscopic treatment was puncture in 23% of cases, partial exeresis in 51% and total removal in 26%.

Participants' opinions of laparoscopic training devices after a basic laparoscopic training course.

BACKGROUND: Basic laparoscopic skills are initially best taught and practiced in an inanimate setting. Various devices are used to aid in this education of laparoscopic skills. These devices range from simple box trainers to sophisticated virtual reality trainers. This investigation tested the hypothesis that participants would prefer one trainer to another trainer. METHODS: Preclinical medical students volunteered for this study. All underwent a porcine laboratory. The students were then divided into 3 groups by method of training: group A--a virtual reality trainer (MIST-VR), group B--an inanimate box trainer (LTS 2000), and group C--both trainers. Each group participated in 10 laboratories with the assigned trainer(s). After completion of the laboratories, all students underwent a similar porcine laboratory. During this laboratory, opinions of each trainer and specific tasks were ascertained from each student. RESULTS: No statistical difference was seen between groups A and B when asked if their specific trainer helped their skills, was realistic, helped in the animal laboratory, and was interesting. When group C was asked the same questions about each trainer, no statistical difference was seen except that 47% thought the MIST-VR was not realistic as opposed to 0% who thought the LTS 2000 was not realistic (P <.003). The level of difficulty of each task correlated with how much the specific task helped in development of skills for both trainers (P <.0001). In group C, 89% of the participants thought the LTS 2000 helped more that the MIST-VR and 56% thought the LTS 2000 was more interesting than the MIST-VR. In addition, 83% of students in group C chose LTS 2000 when asked to pick only one trainer. CONCLUSIONS: While virtual reality trainers may have some advantages, most participants feel that inanimate box trainers help more, are more interesting, and should be chosen over virtual reality trainers if only one trainer is allowed. Further studies need to investigate if the opinions affect participants' utilization of these trainers.

Taste change after laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding.

BACKGROUND: Many patients have described changes in taste perception after weight loss surgery. Our hypothesis was that patients develop postoperative changes in taste that vary by bariatric procedure. METHODS: Patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic adjustable gastric banding (LAGB) completed a 23-question institutional review board-approved survey postoperatively regarding their degree and type of taste changes and food aversion and how these influenced their eating habits. RESULTS: A total of 127 patients participated. After removing the inadequately completed surveys, 82 LRYGB and 28 LAGB patients were included. Of these, 87% of LRYGB and 69% of LAGB patients believed taste is important to the enjoyment of food. More LRYGB patients (82%) than LAGB patients (46%) reported a change in the taste of food or beverages after surgery (P <.001). In addition, 92% of LAGB versus 59% of LRYGB patients characterized the change as a decrease in the intensity of taste (P <.05). Additionally, 68% of LRYGB and 67% of LAGB patients found certain foods repulsive and had developed aversions. Also, 66% of LRYGB and 70% of LAGB patients believed the taste changes were greater than expected preoperatively. Most patients (83% of LRYGB and 69% of LAGB patients) agreed that the loss of taste led to better weight loss. CONCLUSION: Although most LRYGB and many LAGB patients experienced taste changes and food repulsion postoperatively, procedural differences were found in these taste changes. Taste changes need to be investigated further as a possible mechanism of weight loss after bariatric surgery.

[Laparoscopic treatment of perforated duodenal ulcers. Results of a retrospective multicentric study. French Society of Laparoscopic Surgery].

STUDY AIM: The aim of this multicentric retrospective study was to report procedures, mortality and morbidity rate in a series of patients operated on for perforated duodenal ulcer with a laparoscopic approach. PATIENTS AND METHODS: Four-hundred and nineteen patients from 18 centers were included. The duration of the study was ten years (1990 to 1999). There were 299 men and 120 women aged from 19 to 98 years (mean: 48 years). The ASA scores were as follows: I (48.7%), II (31.3%), III (17.5%), IV (2.5%). The mean duration between the onset of perforation and the time of operation was 13.4 hours (range: 1-70). The surgical procedures were suture (76.7%), epiploplasty (9.9%), only irrigation of the abdominal cavity (2.7%). RESULTS: Conversion into laparotomy was performed in 10.6% of the patients. Mean operative time was 85 minutes. The morbidity and mortality rates were 13.4 and 1.4% respectively. Seventeen patients were reoperated because of fistula (n = 5), intra-abdominal abscess (n = 5), small bowel obstruction (n = 4), bleeding ulcer (n = 1), iatrogenic perforation of the gallbladder (n = 1) and small bowel (n = 1). Mean hospital stay was 8.5 days. All patients were discharged with a medical treatment of the peptic ulcer disease and in most of the cases, with antibiotics for Helicobacter pylori eradication. Six patients out of 96 with a medical history of chronic peptic ulcer underwent a vagotomy. CONCLUSION: Laparoscopic repair of perforated duodenal ulcer is a safe option providing low rates of morbidity, reoperation and mortality, and can be considered the treatment of choice.
