Abstract
INTRODUCTION Achalasia is a primary motor disorder of the oesophagus characterised by absence of peristalsis and insufficient lower oesophageal sphincter relaxation. With new advances and developments in achalasia management, there is an increasing demand for comprehensive evidence-based guidelines to assist clinicians in achalasia patient care. METHODS Guidelines were established by a working group of representatives from United European Gastroenterology, European Society of Neurogastroenterology and Motility, European Society of Gastrointestinal and Abdominal Radiology and the European Association of Endoscopic Surgery in accordance with the Appraisal of Guidelines for Research and Evaluation II instrument. A systematic review of the literature was performed, and the certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation methodology. Recommendations were voted upon using a nominal group technique. RESULTS These guidelines focus on the definition of achalasia, treatment aims, diagnostic tests, medical, endoscopic and surgical therapy, management of treatment failure, follow-up and oesophageal cancer risk. CONCLUSION These multidisciplinary guidelines provide a comprehensive evidence-based framework with recommendations on the diagnosis, treatment and follow-up of adult achalasia patients.

Abstract
BACKGROUND AND AIMS Intra-abdominal local recurrences of colorectal cancer can be difficult to localize and excise because they are not easily visible or palpable. MATERIALS AND METHODS We report on our experience using the computed tomography-guided harpoon technique to locate and resect these nodules in seven patients. RESULTS No complications were recorded during the procedures. Six nodes were malignant and all margins were tumor free. CONCLUSIONS Harpoon placement for intra-abdominal local recurrences of colorectal cancer is a feasible and useful technique that provides direct localization and complete excision of lesions.

Abstract
BACKGROUND The incidence of perineal hernia after abdominoperineal excision and extralevator abdominoperineal excision ranges from 1 to 26%. In this systematic review, we compared surgical options and postoperative outcomes of perineal hernia repair in this setting from 2012 to 2016 with findings in a review of publications 1944-2011. METHODS We searched the PubMed database using the keywords "hernia" AND "perineum" identified 392 papers published from 1946 to 2016. Two hundred and ninety-six papers published before 2012 were excluded and 96 were found to be potentially relevant. RESULTS Twenty-one studies with a total of 108 patients were included in the final analysis. Perineal hernia repair was performed using the perineal approach in 75 patients (69.44%), the laparoscopic approach in 25 patients (23.14%), the open abdominal approach in three patients (2.77%) and the laparoscopic perineal approach in three patients (2.77%) and the open abdominoperineal approach in two patients (1.8%). Non-absorbable mesh was used in 41 (37.96%) of cases, composite mesh in 20 (18.51%) and biological mesh in 19 (17.59%). Flap reconstruction was used in 25 patients (23.14%). First and second recurrences were observed in 26 (24.07%) and 7 (26.92%) cases, respectively. CONCLUSIONS Comparison of perineal hernia repair from 1944 to 2011 and from 2012 to 2016 showed that perineal and laparoscopic approaches are currently the most commonly used techniques. Primary defect closure was abandoned in favor of synthetic or composite mesh placement. Use of flap reconstruction spread rapidly and the recurrence rate was low. Randomized control trials and a larger sample size are needed to confirm these data and to develop a gold standard treatment for secondary hernia repair after abdominoperineal excision or extralevator abdominoperineal excision.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) offers better short-term results than open surgery for the treatment of immune thrombocytopenic purpura (ITP), but long-term follow-up is required to ensure its efficacy. The remission rate after splenectomy ranges from 49 to 86% and the factors that predict a successful response to surgical management have not been clearly defined. The goal of this study was to determine the preoperative factors that predict a successful outcome following LS. METHODS From February 1993 to December 2003, LS was consecutively performed in a series of 119 nonselected patients diagnosed with ITP (34 men and 85 women; mean age, 41 years), and clinical results were prospectively recorded. Postoperative follow-up was based on clinical records, follow-up data provided by the referring hematologist, and a phone interview with the patient and/or relative. Univariate and multivariate analyses were performed for clinical preoperative variables to identify predictive factors of success following LS. RESULTS Over a mean period of 33 months, 103 patients (84%) were available for follow-up with a remission rate of 89% (92 patients, 77 with complete remission with platelet count > 150,000). Eleven patients did not respond to surgery (platelet count < 50,000). Mortality during follow-up was 2.5% (two cases not related to hematological pathology and one case without response to splenectomy). Preoperative clinical variables evaluated to identify predictive factors of response to surgery were sex, age, treatment (corticoids alone or associated with Ig or chemotherapy), other immune pathology, duration of disease, and preoperative platelet count. In a subgroup of 52 patients, we also evaluated the type of autoantibodies and corticoid doses required to maintain a platelet count > 50,000. Multivariate analysis showed that none of the variables evaluated could be considered as predictive factors of response to LS due to the high standard error. CONCLUSION Long-term clinical results show that LS is a safe and effective therapy for ITP. However, a higher number of nonresponders is needed to determine which variables predict response to LS for ITP.

Abstract
BACKGROUND Several studies have shown that laparoscopic surgery (LS) minimizes surgical trauma and the immune function is better preserved. Another major advantage of LS is the lower incidence of septic complications. However, several in vitro studies have shown that CO(2) severely impairs macrophage physiology. In theory, this would reduce the ability to respond to peritoneal contamination. However, there is some controversy in view of the evidence of a better preserved peritoneal response to sepsis. This study analyzed the early response of the peritoneum to contamination in a CO(2) ambience. METHODS A total of 192 CD-1 mice were distributed in three groups: group 1, laparotomy (LAP, n = 64); group 2, CO(2) laparoscopy (CO(2)-LC, n = 64); and group 3, wall lift laparoscopy (WL-LC, n = 64). Mice in each group were randomized to receive 1 ml of Escherichia coli suspension (1 x 10(4) colony-forming units/ml) or saline. Peritoneal fluid was obtained at 1.5, 3, 6, and 12 h after surgery. Monocyte chemoattractant protein-1 (MCP-1), interleukin-6 (IL-6), and prostaglandin E(2) (PGE(2)) were measured. RESULTS MCP-1 levels were significantly greater and higher earlier in group 2 (CO(2)-LC) than in group 1 (LAP) (p < 0.007). Simultaneously, the increment in the traction group (WL-LC, group 3) was significantly higher (p < 0.002) than after laparotomy, with no differences in group 2 (CO(2)-LC). When a contamination was added to the laparotomy subgroup, there was a significant increase compared to the group without contamination (p < 0.5). MCP-1 modifications after contamination in the LAP group were statistically significant and appeared later than in the WL-LC (p < 0.002) and CO(2)-LC groups (p < 0.02). For IL-6, the three models presented a significant increase in the noncontaminated groups. This occurred significantly later in the LAP group. Simultaneously, the increase in IL-6 occurred earlier and was significantly higher in the WL-LC group compared to the LAP group (p < 0.003), without differences between CO(2)-LC and wall lift groups. Significant differences between contaminated and noncontaminated subgroups were only observed in the LC-CO(2) groups. When contaminated, the traction model sustained a higher and earlier rise in IL-6 levels compared to the LAP and LC-CO(2) groups (p < 0.001). For PGE(2), The three models showed a significant increase in PGE(2) levels in the noncontaminated groups. However, there were no significant differences between them. In the contaminated groups, there was no statistical difference between the groups. CONCLUSION Despite a transient impairment of the immediate peritoneal response to a septic challenge, the degree of injury with LS is lower than that with open surgery, and abdominal infection can therefore be better controlled.

Abstract
INTRODUCTION Sigmoid volvulus is responsible for 8% of all intestinal obstructions. The most frequent presentation is in the elderly, with it occurring exceptionally in young people. Surgical resection is mandatory to prevent recurrence. Laparoscopic maneuvers in the long and distended bowel are difficult, and not much experience with these procedures has been reported. MATERIALS AND METHODS, AND RESULTS A 21-year-old man with antecedents of constipation had two episodes of rectal prolapse, and one episode of acute volvulation treated with decompressive endoscopy. A laparoscopic exploration was performed for definitive treatment. Transanal intubation with a large-bore tube permitted deflation of the bowel. A deep Douglas's pouch was observed with a mobile sigmoid loop that intussuscepted the rectum. A proctosigmoidectomy including the 5 cm of the upper rectum was performed without incident. CONCLUSION Laparoscopic management of suboclusive colonic volvulus is feasible. Intraopertive transanal intubation permits deflation the loop and facilitates manipulation.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) has been demonstrated as an effective and safe treatment for hematological disorders requiring spleen removal, especially in cases of normal-sized spleens. However, although results are promising, long-term outcome data are lacking. We reviewed our clinical experience with LS in a series of 255 cases, with particular attention to the long-term outcome related to the disease process requiring LS. METHODS From February 1993 to October 2003, LS was attempted in 255 patients (100 males and 155 females with a mean age of 45 +/- 19 years) and clinical information was recorded in a prospective database. Indications for splenectomy included idiopathic thrombocytopenic purpura (ITP) (n = 115), HIV-ITP (n = 9), Evans syndrome (n = 6), autoimmune hemolytic anemia (AIHA) (n = 13), hereditary spherocytosis (HS) (n = 19), hematologic malignancy (n = 66), thrombotic thrombocytopenic purpura (n = 1), and others (n = 26). Long-term postoperative follow-up evaluation was obtained through clinical notes, follow-up visits by the referring hematologist, and by phone interviews both with patients and with the referring hematologist. RESULTS A total of 186 patients (73%) were available for a mean follow-up of 35 months (range, 1-104). Of the ITP patients, 87 (76%) were followed up, with a remission rate of 89% (complete remission in 75%). A similar remission rate was observed in ITP-HIV; in patients available for follow-up (78%), complete remission was achieved in 83%. In Evans, complete remission was achieved in all patients available for follow-up (67%). Clinical response for hemolytic disease ranged between 70% for AIHA and 100% for HS. In the malignant group, the late mortality rate was 22%. The mortality rate in the miscellaneous group was 5%. No cases of splenectomy-related sepsis occurred during follow-up. CONCLUSIONS LS offers advantages for all types of splenic diseases requiring surgery. It provides not only good clinical short-term outcome but also satisfactory long-term hematological results.

Abstract
BACKGROUND Initial experience with the laparoscopic repair of paraesophageal and type III mixed hiatal hernias showed that it is safe and feasible, with excellent immediate and short-term results. However, after a longer follow-up, a recurrence rate of < or =40% has been demonstrated. Data related to the outcome of paraesophageal hernia repair and the recurrence rate are still lacking. Quality-of-life scores may offer a better means of assessing the impact of surgical treatment on the overall health status of patients. Therefore, we performed prospective evaluation of anatomic and/or symptomatic recurrences after paraesophageal or large hiatal hernia repair. In addition, we investigated the correlation between recurrence and the patient's quality of life. METHODS All patients after who had undergone repair of paraesophageal of mixed hiatal hernia were identified prospectively from a database consisting of all patients who had had laparoscopic operations for gastroesophageal pathology at our hospital between February 1998 and December 2002. The preoperative symptoms were taken from patients' clinical files. In March 2003, all patients with > or =6 months of follow-up had a barium swallow and were examined for radiological and clinical signs of recurrence. Thereafter, the patients' quality of life after surgery was evaluated using three standard questionnaires (Short Form 36 [SF-36], Glasgow Dyspepsia Severity Score [GDSS], and Gastrointestinal Quality of Life Index [GIQLI]. RESULT During the study period, 46 patients had been operated on. The mean age was 63 years (range, 28-93). Thirty seven of them had a follow-up of > or =6 months. Eight patients (21%) had postoperative gastrointestinal symptoms. Barium swallow was performed in 30 patients (81%) and showed a recurrence in six of them (20%). According to SF-36 and GDSS, the patients' postoperative quality of life reached normal values and did not differ significantly from the standard values for the Spanish population of similar age and with similar comorbidities. Successfully operated patients reached a GIQLI value comparable to the standard population. However, symptomatic patients had significantly lower GIQLI scores than the asymptomatic or the Rx-recurrent group. CONCLUSION The laparoscopic treatment of large paraesophageal and mixed hiatal hernias is not only feasible and safe but also offers a good quality of life on a midterm basis. However, the anatomic and functional recurrence rate is high. The next step is to identify the subset of patients who are at risk of failure and to establish technical alternatives that would ensure the durability of the repair.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) is considerably more difficult to perform when the spleen is enlarged. The new technique of hand-assisted designed technique aimed to assist laparoscopic surgery allows the surgeon to insert his or her hand into the abdomen while maintaining the pneumoperitoneum, thus recovering the tactile sensation lost in conventional laparoscopic surgery. OBJECT In this study, we compared the immediate results of conventional LS and hand-assisted LS (HALS) in cases of splenomegaly. METHODS Between February 1993 and August 2001, 200 LS were attempted at two university hospitals. In 56 cases, splenomegaly (final spleen weight >700 g) was observed clinically or detected on radiological examination. We compared the first 36 patients operated on by conventional LS (group I) with the last consecutive 20 patients, who underwent HALS (group II). The study parameters were operative time, conversion rate, transfusion rate, morbidity and length of hospital stay. RESULTS The groups were comparable in terms of age (58 +/- 13 [ranges, l9-82] vs 58 +/- 16 years [range, 44-84] (ns), diagnosis, and spleen weight (1425 +/- 884 [range, 700-3400]) vs 1753 +/- 1124 g [range, 720-4500] (ns). HALS was associated with less morbidity (36% vs 10%) (ns), a shorter operative time (177 +/- 52 [range, 95-300]) vs 135 +/- 53 min [range, 85-270] (p <0.009), and a shorter hospital stay (6.3 +/- 3.3 [range, 3-14]) vs 4 +/- 1.2 [range, 2-7] days (p <0.05). CONCLUSION In cases of splenomegaly, HALS assisted laparoscopic surgery significantly facilitates the surgical maneuvers during LS while maintaining the advantages of a purely laparoscopic approach.

Abstract
BACKGROUND Hand-assisted laparoscopic surgery (HALS) represents a useful alternative to conventional laparoscopic surgery (LS). Its potential advantages--(a quicker, safer procedure and less need to convert to open surgery) are due to the recovery of tactile feedback. However, HALS requires the performance of a mini-laparotomy when surgery commences, and the wound is stretched and compressed throughout the procedure. In addition, it is associated with a more intense manipulation of the intraabdominal viscera. All of these factors increase the surgical trauma, it is not known whether HALS maintains the minimally invasive characteristics of conventional LS. Therefore, we set out to study the applicability, immediate clinical outcome, inflammatory response, and cost of HALS compared with conventional LS using colectomy as a model. METHODS We performed a prospective randomized trial comparing laparoscopic-assisted colectomy with HAL colectomy. The aims of the study were to assess (a) perioperative features, including time, advantages, and conversion; (b) the patient's immediate clinical response, including recovery of bowel sounds, refeeding time, postoperative pain, local and general morbidity, and hospital stay; (c) the effect on the inflammatory response, using interleukin-6 (ILG) and C-reactive protein (CRP) measurements; (d) oncological issues, including intraoperative cytology and features of the specimen; and (d) the relative costs of the two procedures. RESULTS A total of 54 patients were enrolled in the study, 27 laparoscopic and 27 HALS. The operative times were similar, but HALS was associated with a far lower conversion rate--7% vs 23%. Immediate clinical outcomes, oncological features, and costs were similar for the two procedures, but HALS was associated with a significantly greater increase in IL6 and CRP than the conventional laparoscopic procedure. CONCLUSION This comparative study shows that HALS simplifies difficult intraoperative situations, reducing the need for conversion. Although it is a more aggressive procedure, HALS preserves the features of a minimally invasive approach, maintains all of the oncological features of conventional laparoscopic surgery, and does not increase the cost. HALS should therefore be considered as a useful adjunct when difficult situations arise during conventional laparoscopic colectomy.

Abstract
Gallbladder stasis and gallstone formation are well-known complications of both fasting-associated total parenteral nutrition (TPN) and long-term treatment with octreotide. Additive noxious effects to hepatobiliary function may develop when both therapies are given together as treatment of enteric fistulae. The aim of this study was to assess the risk of gallstone formation during treatment with TPN and octreotide separately and in combination. We studied four groups of New Zealand rabbits (n = 32) during a 2-week intervention period: 14 chow-fed controls; 6 fasted and TPN-fed; 6 chow-fed and administered octreotide, and 6 fasted and treated with both TPN and octreotide. After treatment, the bile duct was cannulated and the gallbladder and liver tissue were obtained for histological analysis. Hepatic and gallbladder bile were retrieved for microscopic examination and measurement of biliary lipids, bilirubin, calcium, total protein, and cholesterol nucleation time. The chemical composition of gallstones was also analyzed. The results of the study suggest that simultaneous administration of these two therapies in rabbits has additive effects on gallbladder stasis and bile lithogenicity. The administration of both treatments can play an important role in the formation of calcium palmitate gallstones in these animals.

Abstract
Laparoscopic splenectomy (LS) is an alternative to open surgery. However, there is a theoretic risk of splenosis and abdominal cavity dissemination of splenic cells if the splenic capsule is broken, as seen by experimental evidence of tumoral cell mobilization by the pneumoperitoneum. We evaluated the features of splenosis after splenectomy operated via an open approach or under laparoscopic control in an experimental model in the rat. A total of 65 Sprague-Dawley rats were distributed in seven groups that included the open approach, CO2 pneumoperitoneum LS, or wall lift LS with or without a splenic graft. Splenic function was evaluated 90 day later through (1) scintigraphy with Tc-labeled heat-damaged erythrocytes; (2) determination of circulating "pitted" cells; and (3) analysis of the distribution of splenic pulp in the peritoneal cavity. Scintigraphy did not show viable residual tissue in any group after splenectomy; splenic activity in the splenic fossa was observed in 40% of the animals with grafts. Splenectomy increased the "pit" cell count, but it was reduced to normal values with a splenic graft. Necropsy showed normal splenic tissue in the splenic fossa in 100% of animals with a graft. Abdominal implants were observed significantly more frequent after CO2 LS than after the open surgery or a wall lift LS (80% vs. 20% vs. 30%; p < 0.05). In addition, trocar site implants were observed with CO2 LS (n = 3) or wall lift LS (n = 2), whereas there were no implants in the wound in the open group. We conclude that in an experimental rat model the pneumoperitoneum may facilitate abdominal splenosis after LS if the splenic capsule is ruptured or if splenic tissue spills compared with surgery without gas (open or laparoscopic).

Abstract
Hand-assisted laparoscopic surgery (HALS) permits recovery of the tactile sensation and facilitates manipulation of solid organs. Our preliminary experience in laparoscopic splenectomy (LS) shows its advantages, with a substantial reduction of operative time, while maintaining the advantages of a less aggressive surgical approach. The role of HALS in cases of splenomegaly or trauma seems to be clear. It can also be considered as an alternative to conventional conversion in cases of intraoperative complications or unclear anatomy. The role of HALS for normal-sized spleens is more controversial because there is a well-systematized, conventional LS technique available, which is followed by optimal clinical outcome LS in hands of a skilled surgeon.

Abstract
INTRODUCTION Laparoscopic splenectomy (LS) offers superior visualization and access to the spleen and avoids the major laparotomy incision necessary in open splenectomy (OS). This review summarizes the current knowledge of laparoscopic techniques for splenectomy from the perspective of surgeons whose combined experience now totals 340 cases. BACKGROUND AND DISCUSSION While LS has been applied across the spectrum of splenic diseases, it is most indicated in treatment of a benign hematologic condition with a normal or slightly enlarged spleen as seen in autoimmune thrombocytopenic purpura (ITP), autoimmune deficiency syndrome-related ITP, hemolytic anemia, or spherocytosis. Both anterior and lateral approaches have been used for LS. While benefits of the anterior approach include access to the splenic artery along the superior border of the pancreas within the lesser sac, thus securing vascular control early in the procedure, the lateral approach allows for improved exposure of and access to the splenic pedicle. Also, mechanics and sequence of dissection are enhanced and more intuitive to the surgeon using the lateral approach, and the tail of the pancreas is more easily identified. Potential perioperative complications of LS include hemorrhage, injury to the tail of the pancreas, and deep vein thrombosis. The most common criticisms facing LS are the potential for missed accessory spleens, longer operating time, and greater operating room costs compared to OS. However, while LS requires a longer operating time than OS, studies indicate shorter postoperative hospital stays for LS versus OS patients in comparable cases, which can, in turn, reduce the total hospital cost for the procedure. CONCLUSION Although LS continues to pose certain technical challenges--such as management of the massive spleen, specimen extraction, and identification of remotely located accessory spleens--its advantages over OS in terms of faster postoperative recovery, shorter hospital stay, and equivalent or lower perioperative morbidity are now well established. Indications for LS and more laparoscopic spleen-conserving surgery are likely to broaden.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) is widely accepted for treatment of benign diseases, but there are few reports of its use in cases of haematological malignancy. In addition, comparative studies with open operation are lacking. Malignant haematological diseases have specific clinical features-notably splenomegaly and impaired general health-which can impact on the immediate outcome after LS. The immediate outcome of LS comparing benign with malignant diagnoses has been analysed in a prospective series of 137 operations. PATIENTS AND METHODS Between February 1993 and April 2000, 137 patients with a wide range of splenic disorders received LS. Clinical data and immediate outcome were prospectively recorded,and age, diagnosis, operation time, perioperative transfusion requirement, spleen weight, conversion rate, accessory incision, hospital stay and complications were analysed. RESULTS The series included 100 benign cases and 37 suspected malignancies. In patients with malignant diseases the mean age was greater (37 years [3-85] vs 60 years [27-82], p<0.01), LS took longer (138 min [60-400] vs 161 min [75-300], p<0.05) and an accessory incision for spleen retrieval was required more frequently (18% vs 93%, p<0.01) because the spleen was larger (279 g [60-1640] vs 1210 g [248-3100], p <0.01). However, the rate of conversion to open operation (5% vs 14%), postoperative morbidity rate (13% vs 22%) and transfusion requirement (15% vs 26%) did not differ between benign and malignant cases. Hospital stay was longer in malignant cases (3.7 days [2-14] vs 5 days [2-14], p<0.05). CONCLUSION LS is a safe procedure in patients with malignant disease requiring splenectomy in spite of the longer operative time and the higher conversion rate.

Abstract
BACKGROUND The advantages of laparoscopic colorectal surgery for selected patients have been well established. However, the applicability of laparoscopic surgery in the whole population of patients with colorectal disease is not well known. METHODS A single-institution medical records review of 269 patients subjected to colorectal surgery was made. Of these, 206 open colorectal procedures were performed, and data were reviewed retrospectively. In addition, 63 patients were subjected to laparoscopy, and their data were recorded prospectively. An analysis of the existence of factors that contraindicate laparoscopic colorectal surgery was done. These factors were of two types: absolute (urgent intervention, severe cardiopulmonary disease, advanced liver cirrhosis, tumor invasion into adjacent organs, simultaneous major surgery) and relative (midrectal tumors, tumors in the transverse colon, bulky tumors, more than two previous infraumbilical operations, previous intestinal surgery, and previous peritonitis). RESULTS Factors that could contraindicate the laparoscopic approach were found in 118 patients (44%). The most common were urgent intervention (40%), midrectal tumors (19%), locally advanced cancer (13%), previous intestinal surgery (13%), and tumors >10 cm (6%). We considered 25% of the contraindications to be absolute and 19% relative. Taking these exclusion criteria into consideration when selecting patients for laparoscopic surgery, the conversion rate in our initial laparoscopic series (63 cases) was 13%. CONCLUSION The indication for laparoscopic surgery for patients with colorectal disease is superior to 60% (absolute 56%, relative 81%). When using appropriate selection criteria, the conversion rate may be maintained below 10%. Preoperative selection of patients with colorectal disease allows optimal use of the advantages of laparoscopic surgery.

Abstract
HYPOTHESIS Analysis of the type and characteristics of complications after laparoscopic splenectomy may permit the identification of clinical factors with predictive value for the development of complications. DESIGN Univariate and multivariate analysis of factors related to complications in a prospective series of laparoscopic splenectomies. SETTING A large tertiary referral university-teaching general hospital. PATIENTS One hundred twenty-two nonselected consecutive patients, in whom laparoscopic splenectomy was attempted between February 1993 and July 1999. INTERVENTION Laparoscopic splenectomy. MAIN OUTCOME MEASURES Immediate complications classified according to the Clavien score. Univariate and multivariate analyses were performed of complications related to age, sex, body mass index, and malignant nature of the hematologic disease; preoperative hematocrit and platelet count; operative time; operative position; need of accessory incision; transfusion status; learning curve; and existence of comorbid diseases. RESULTS One hundred thirteen laparoscopic splenectomies were completed (conversion rate, 7.4%). Twenty patients (18%) developed 23 complications. All were Clavien type I or II, without mortality. One complication was intraoperative (diaphragmatic perforation), and 22 were postoperative: 6 pulmonary (26%), 3 fever (13%), 8 hemorrhagic (35%) (5 episodes of postoperative bleeding and 3 abdominal wall hematomas), and 6 others (26%). Ten (43%) of the 23 were technically related. Univariate analysis showed that complications were only related to age (mean +/- SD, 55 +/- 15 vs 39 +/- 17 years; P<.008) or transfusion (50% vs 11%; P<.001). Multivariate analysis showed that the learning curve (P<.005; 95% confidence interval, 2.46), age (P<.001; 95% confidence interval, 1. 04), spleen weight (P<.009; 95% confidence interval, 1.00), and malignant neoplasm diagnosis (P<.007; 95% confidence interval, 3.82) were independent predictors of complications. CONCLUSIONS Laparoscopic splenectomy is feasible, and the incidence of severe complications is reduced. However, a high proportion of these complications are technique related. Laparoscopic splenectomy requires great technical care but offers major clinical advantages, even in less favorable situations, such as in patients with splenomegaly or with malignant neoplasms.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) is now regarded as the treatment of choice for autoimmune thrombopenia (ITP). However, there have been few reports describing the application of LS to other splenic diseases, such as malignant entities and conditions associated with splenomegaly. Hematological diseases have specific clinical features that can influence immediate outcome after LS. Although the long-term effects of LS are unknown, a risk of splenosis has been suggested. Therefore, we designed a study to analyze the impact of primary hematological disease on immediate and late outcome in a prospective series of LS patients. METHODS We performed a prospective analysis of 111 LS done between February 1993 and March 1999. The patients were classified by hematological indications into the following four groups: (a) group 1, low platelet count. This group was further subdivided into group 1A, idiopathic thrombocytopenic purpura (ITP) (n = 48) and group 1B, HIV-related ITP (n = 8); (b) group 2, anemia. This group was further subdivided into group 2A, autoimmune hemolytic anemia (n = 8), and group 2B, spherocytosis (n = 11); (c) group 3, malignancy (n = 28); and (d) group 4, others (n = 8). Immediate outcomes were recorded prospectively. Hematological status and late complications were reviewed after a mean follow-up of 24 +/- 18 months. RESULTS There were no significant differences between the groups in terms of conversion, transfusion requirements, and morbidity, although transfusion and morbidity were slightly higher in group 3. However, hospital stay was significantly longer in groups 3 and 4 than in groups 1 and 2. Long-term follow-up showed satisfactory hematological results in >/=75% of patients (group 1A, 82%; group 1B, 88%; group 2A, 88%; group 2B, 100%; group 3, 75%; group 4, 88%). Overall, late morbidity was 8.3% and mortality was 6.2%, mainly due to deaths in group 4 (six of 22 patients). CONCLUSION LS is a safe and reproducible procedure for most hematological indications, with a similar immediate outcome for benign diseases and a long-term hematological response comparable to the standard results that have been observed in open series.

Abstract
INTRODUCTION It has been observed that the metabolic response to surgical injury is less after laparoscopic surgery than after open surgery. However, the effect of laparoscopic surgery on surgical infection has not been given much attention in the surgical literature, even though it may decrease the incidence of infectious complications. The objective of this study was to assess the influence that laparoscopic surgery has on surgical infection and to highlight certain controversial aspects. METHODS A review of the literature was undertaken to examine the relationship between laparoscopic surgery and surgical infection. This was achieved primarily by using PubMed Medline as a source of material. RESULTS AND CONCLUSION Laparoscopic surgery is associated with better preservation of the immune system than open surgery. This results in a decreased incidence of infectious complications. Although carbon dioxide pneumoperitoneum affects the peritoneal response to injury, it seems to have no harmful effect in terms of intra-abdominal infection. Nevertheless, at laparoscopic operation the virulence of intestinal micro-organisms should be recognized and, while knowing the advantages of minimally invasive surgery, the surgeon should consider the complexity of this technique. Furthermore, maintenance of laparoscopic instruments should be governed by the same norms as those used in open surgery; recommendations offered by the manufacturers should be respected.

Abstract
UNLABELLED Endoscopic removal is the treatment of choice for colorectal polyps. However, this therapeutic option is limited by the size of the tumor, sessile implantation, or technical impossibility. These cases are ideal for laparoscopic treatment because of the anatomy of the colon is and because the risk of manipulating a malignant lesion is lower. However, there is the added difficulty of identifying the lesion. In other cases, unsuspected neoplastic invasion of an endoscopically removed polyp makes surgery necessary. AIM To evaluate the results of laparoscopic surgery in the treatment of colorectal polyps. MATERIAL AND METHODS Between December 1997 and November 1999, 270 endoscopic polypectomies were performed. In 15 patients, endoscopic removal was technically impossible or contraindicated. These patients were treated laparoscopically. One patient who was found to have an invasive carcinoma following polypectomy was also treated laparoscopically. The technical characteristics of the operation (duration, conversion, morbi-mortality, postoperative stay, size of the polyp and number of ganglions) were analyzed and compared with 43 other laparoscopic operations in the colon carried out for other reasons (n = 43). RESULTS In nine patients, surgery was indicated because of the size of the polyp, in three for technical reasons, in three for severe atypia and in one because of an invasive carcinoma following polypectomy. The operation was completed by laparoscopy in 15 patients (94%). Ten right hemicolectomies, five sigmoidectomies and one anterior resection assisted by hand port were carried out. The diameter of the lesions was 4.4 +/- 2.4 cm. Histological studies revealed carcinoma in situ in five, infiltrating carcinoma in two, non-malignant adenoma in six and lipoma in one. Comparison of the results of patients who underwent colectomy for polyps with those of the group who underwent surgery for other reasons revealed lower morbidity (24% vs. 22%) and need for conversion (7% vs. 16%), as well as a significant decrease in operating time (130 +/- 10 vs. 148 +/- 32 min, p < 0.05) and in postoperative stay (6.6 +/- 1.4 vs. 8.3 +/- 2.5 days, p < 0.02). CONCLUSION Laparoscopic colonic resection is particularly suitable in the treatment of colorectal polyps.

The diagnosis of achalasia is based on the patient's symptoms and on manometric studies although other diseases present similar symptomatology. To present an elderly woman clinically and manometrically diagnosed with achalasia of the cardia who was treated by dilatation. When the patient relapsed and was surgically treated she was found to have and esophageal adenocarcinoma. When considering a diagnosis of achalasia, alternative diagnoses (especially neoplasias) should be borne in mind, especially in unusual situations, such as rapid onset or in the elderly.

Abstract
OBJECTIVE Assessment of the perceived quality of care for inguinal hernia repair procedures. DESIGN A two-step descriptive study using specific questionnaires. SETTING A tertiary care University Hospital. SUBJECTS Random sample of patients diagnosed of inguinal hernia in 1996. Group A, patients seen at the outpatient clinic before admission; group B, patients seen for follow-up after the surgical procedure. INTERVENTIONS Two different questionnaires were used. MAIN OUTCOME MEASURES validity of the questionnaire was evaluated using Cronbach's alpha value. Scores were measured using the z value. RESULTS Total number of patients was 194. Both groups were comparable. The questionnaire was able to explain 66.3% of the variance. The Cronbach's alpha value was 0.90. Scores recorded were significantly different (P < 0.01) regarding the health care workers' attitude and hospital commodities' variables (rated as better than expected). Differences in scores for information supplied, overall results of the surgical procedure and food variables were not statistically significant. CONCLUSIONS (i) The study of several fields where the patient's expectations are higher or lower contributes to prioritizing efforts to improve quality in the Surgery Department. (ii) The differences seen strongly suggest the need for patient's satisfaction surveys to be specific by diagnosis/dimension and adapted to patients' expectations.

Abstract
Laparoscopic surgery in small-animal models provides insight into basic physiopathological aspects of laparoscopy. However, laparoscopic work in small animals entails precise skill and long operative times. We present an easy and shorter three-trocar procedure (two of 5 mm and one of 2 mm) for splenectomy in a rat model. Miniature instruments (2-mm forceps, 3-mm endoscope, and 5-mm endoapplier) were used. Forty laparoscopic splenectomies were attempted. The operative time was 30 +/- 4 minutes. There was no postoperative mortality, and scintigraphy ruled out the presence of residual splenic tissue. Laparoscopic splenectomy in a rat is feasible. When using experimental laparoscopic models for splenectomy, an easy technique is of great importance in order to avoid cumbersome manuevers that can cause rupture of the splenic capsule and cell spillage or postoperative bleeding. The development of surgical laparoscopic instruments with thinner devices (5-mm endoclip appliers and 2-mm ports and instruments) facilitates the procedure and permits a significantly shorter operative time.

Abstract
BACKGROUND Laparoscopic surgery has a lower incidence of surgical infection than open surgery. Differential factors that may modify the bacterial biology and explain this finding to some extent include CO(2) atmosphere, less desiccation of intraabdominal structures, fewer temperature changes, and a better preserved peritoneal and systemic immune response. Previous data suggest that the immune response and acute phase response are better preserved after laparoscopy. Therefore, we designed a study to evaluate the early peritoneal response to sepsis in an experimental peritonitis model comparing open surgery with CO(2) and abdominal wall lift laparoscopy. METHODS The study subjects comprised 360 mice distributed into the following four groups: group 1, n = 72 (controls); group 2, n = 96 (open surgery), 2-3 cm laparotomy, with abdominal cavity exposed to the air for 30 min; group 3, n = 96, CO(2) laparoscopy (5 mmHg pneumoperitoneum) for 30 min; group 4, n = 96, wall lift laparoscopy for 30 min. Intraabdominal contamination in the four groups was induced with 1 ml of E. coli suspension (1 x 10(4) CFU/ml) 10 min before abdomen closure. Peritoneal fluid and blood samples were obtained 1.5, 3, 24, and 72 h after surgery, and TNF, IL-1, and IL-6 were measured (via ELISA), as well as quantitative culture. RESULTS The number of CFU (colony-forming units) obtained in peritoneal fluid and positive blood culture rates were significantly lower in the laparoscopic groups than in the open group. IL-1 peritoneal levels were significantly lower after 24 h and 72 h in the laparoscopy groups. IL-6 levels decreased sharply in the laparoscopy groups at 24 h and 72 h. There were no differences between the two types of laparoscopy models (CO(2) and wall lift). CONCLUSIONS Peritoneal response to sepsis is better preserved after laparoscopy than after open surgery. CO(2) does not seem to influence bacterial growth. According to these findings, laparoscopy entails less local trauma and better preserved intraabdominal conditions.

Abstract
BACKGROUND Laparoscopic splenectomy (LS) is gaining acceptance as an alternative to open splenectomy (OS). However, splenomegaly presents an obstacle to LS, and massive splenomegaly has been considered a contraindication. Analyses comparing the procedure with the open approach are lacking. The purpose of this study was to analyze the effect of spleen size on operative and immediate clinical outcome in a series of 105 LS compared with a series of 81 cases surgically treated by an open approach. METHODS Between January 1990 and November 1998, 186 patients underwent a splenectomy for a wide range of splenic disorders. Of these patients, 105 were treated by laparoscopy (group I, LS; data prospectively recorded) and 81 were treated by an open approach (group II, OS analyzed retrospectively). Patients also were classified into three groups according to spleen weight: group A, <400 g; group B, 400-1000 g; and group C, >1000 g. Age, gender, operative time, perioperative transfusion, spleen weight, conversion rate, mode of spleen retrieval (bag or accessory incision), postoperative analgesia, length of stay, and morbidity were recorded in both main groups. RESULTS Operative time was significantly longer for LS than for OS. However, LS morbidity, mortality, and postoperative stay were all lower at similar spleen weights. Spleens weighing more than 3,200 g required conversion to open surgery in all cases. When LS outcome for hematologic malignant diagnosis was compared with LS outcome for a benign diagnosis, malignancy did not increase conversion rate, morbidity, and transfusion, even though malignant spleens were larger and accessory incisions were required more frequently. Postoperative hospital stay was significantly longer in malignant than in benign diagnosis (5 +/- 2.4 days vs. 4 +/- 2.3 days; p < 0. 05). CONCLUSIONS In patients with enlarged spleens, LS is feasible and followed by lower morbidity, transfusion rate, and shorter hospital stay than when the open approach is used. For the treatment of this subset of patients, who usually present with more severe hematologic diseases related to greater morbidity, LS presents potential advantages.

Abstract
BACKGROUND Several studies have shown the potential advantages laparoscopic splenectomy (LS) over open surgery. The aim of this study has been to evaluate the advantages of LS over open surgery in the treatment of autoimmune thrombocytopenia. PATIENTS AND METHODS 54 consecutive patients splenectomized for the treatment of idiopathic thrombocytopenic purpura (ITP) or HIV-related thrombocytopenia were analyzed. Operative features (operative time, conversion to open surgery, accessory spleens), immediate (stay, analgesia and blood transfusion requirements) and late postoperative features (platelet count), as well as splenectomy-related complications in both surgical procedures were compared. RESULTS Between February 1990 and February 1997, 54 splenctomies were performed for the treatment of autoimmune thrombocytopenia (ITP, n = 47, and HIV-related thrombocytopenia, n = 7). Eighteen were performed through an open approach, and 36 by laparoscopy. Both groups were comparable with regard to age, sex, platelet count, disease duration and body mass index. LS was completed in 34 cases (conversion to open surgery: 5.5%). The incidence of accessory spleens was 11% in the LS group and 5.5% in the open surgery group. Postoperative morbidity (16% vs 28%) and blood requirements (25% vs 33%) were lower after LS, but the differences did not reach statistical significance. Analgesia requirements (7 [SD 3] vs 11 [6]; p < 0.01) and postoperative stay (3.8 [2.6] vs 7.4 [3] days; p < 0.01) were significantly shorter after LS. Following splenectomy, the platelet counts became normal in 72% of patients submitted to LS and 78% of patients in the open surgery group. After 20 and 63 months mean follow-up, one patient in each group developed late complications. CONCLUSION As compared to open surgery, LS offers a better immediate clinical outcome, with similar long-term results.

Abstract
BACKGROUND This study was performed to prospectively assess the impact of the laparoscopic approach to the patterns of port site metastases (PSM) and recurrence rate (RR) of resected colon carcinomas as compared with conventional colectomies. METHODS All patients were included in a prospective randomized trial comparing laparoscopic-assisted colectomy (LAC) versus open colectomy (OC) for colon cancer. The randomization was stratified for localization of the lesion. Patients with metastasic disease at time of the surgery were excluded. Follow-up in the outpatient clinic was done every 3 months for a minimum of 12 months. Endpoints for the study were metastasis at port site and laparotomy incision as well as recurrence rate. RESULTS Of 91 segmental colectomies performed from November 1993 to January 1996, there were 44 LAC and 47 OC. Patient data were similar in both groups (age, sex, Dukes stage, type of operation). Mean follow-up was 21.4 months, with a range of 13 to 41 months. There were no wounds or PSM in those series. RR was similar for both groups. For LAC, it was five of 31 (16.1%); for OC, it was six of 40 (15%). CONCLUSIONS The laparoscopic approach has a recurrence rate similar to that for open procedures for colon cancer. However, additional follow-up of these patients is needed before we can determine whether or not the laparoscopic approach influences overall survival.

Abstract
OBJECTIVE To analyze the impact of spleen size on operative and immediate clinical outcome in a series of 74 laparoscopic splenectomies (LS). SUMMARY BACKGROUND DATA LS is gaining acceptance as an alternative to open splenectomy. However, splenomegaly hinders LS, and massive splenomegaly has been considered a contraindication. METHODS Between February 1993 and September 1997, 74 patients with a wide range of splenic disorders were treated by laparoscopy and prospectively recorded. They were classified into three groups according to spleen weight: group I, <400 g (n = 52); group II, 400 to 1000 g (n = 9); and group III, >1000 g (n = 13). Age, operative time, number of trocars required, need for perioperative transfusion, spleen weight, conversion rate, mode of spleen retrieval (bag or accessory incision), postoperative analgesia requirements, length of hospital stay, and morbidity rates were recorded. RESULTS LS was completed in 69 patients, and the conversion rate was thus 6.7%. Operative time was significantly longer in patients with larger spleens, and an accessory incision was more frequently required. However, there were no significant differences in transfusion rate, length of stay, severe morbidity, or conversion rate. CONCLUSIONS Preliminary evaluation of LS for patients with large spleens suggests that it requires a longer operative time, but it is feasible and may potentially offer the same advantages (shorter stay and faster recovery) as it does to those with smaller spleens.

Abstract
BACKGROUND Bile duct injury (BDI) is a severe complication of laparoscopic cholecystectomy (LC). There is general agreement about the increase of this complication after LC vs open cholecystectomy (OC), but comparative studies are scarce. The aim of this paper has been to compare the incidence and clinical features of BDI after LC vs open procedures. MATERIALS AND METHODS 3,051 OC, performed from June 1977 to December 1988 were retrospectively analyzed and compared with 1,630 LCs performed from June 91 to August 96, for which data were prospectively recorded. Age, sex, type of BDI, performance of intraoperative cholangiography (IOC), underlying biliary pathology, morbidity, mortality, and late morbidity were all analyzed. RESULTS BDI incidence was higher in group II (LC) (N: 16, 0.95%) than in group I, (OC, N: 19. 0.6%). BDI incidence was also higher in the group of patients in which it was necessary to convert to an open procedure (3/109, 2.7%, p < 0.05). BDIs were more frequently diagnosed intraoperatively in group I (OC, 18/19) than in group II (LC, 12/16). In both groups, BDI was more prevalent in cases operated by staff surgeons than residents, mainly in complicated gallbladder patients, with a bile duct of less than 7-mm diameter. Morbidity, postoperative stay, mortality, and late morbidity were similar after a BDI in both types of approach. CONCLUSIONS (1) BDI increases with LC. (2) BDI after LC carries a similar postoperative morbidity and mortality to those after OC. (3) Incidence of BDI in converted cases increases significantly and this constitutes a high-risk group.

Abstract
BACKGROUND Current treatment of malignant melanoma of the leg includes ilioinguinal lymphadenectomy (IIL). Standard open IIL (open IIL) includes sectioning of the inguinal ligament to gain access to the iliac nodes. Extraperitoneal laparoscopic IIL (lap IIL) is a feasible, less aggressive approach. It can be combined with standard superficial lymphadenectomy for treatment of malignant melanoma. DESIGN Comparative, prospective, nonrandomized series. SETTING Tertiary care center. PATIENTS Twelve consecutive, unselected patients with malignant melanoma treated with lap IIL (group 1) were compared with 10 consecutive, unselected patients with malignant melanoma on whom open IIL was performed (group 2). INTERVENTIONS Standard open IIL and laparoscopic extraperitoneal iliac lymphadenectomy (lap IIL) plus superficial groin lymphadenectomy. MAIN OUTCOME MEASURES Operative time, intraoperative complications, requirements of analgesia, total volume of lymphatic drainage, number of lymph nodes retrieved, immediate morbidity, hospital stay, and long-term morbidity were evaluated. RESULTS Operative time was significantly longer for the lap IIL group (group 1) than for the open IIL group (group 2) (177+/-44 vs 140+/-18 minutes, respectively; P<.05), but no patients in group 1 needed conversion to open surgery or developed related complications. Overall lymphatic drainage was significantly lower in group 1 than in group 2 (615+/-518 mL vs 1393+/-793 mL, repectively; P<.01). The number of doses of analgesics (13+/-8 vs 31+/-22, P<.03) and length of postoperative stay (7.3+/-3.3 vs 13+/-5 days, P<.006) were also significantly lower in the laparoscopic group. The overall number of lymph nodes retrieved was similar in both groups (10.2+/-4.6 vs 10+/-3, P=.9). One patient developed a groin hernia of 6 m after open IIL. CONCLUSIONS Laparoscopically assisted IIL offers a less aggressive approach than open IIL and entails less pain and a shorter hospital stay, as we observed in 2 groups with similar oncological results (mainly, a similar number of lymph nodes retrieved) who were treated with one procedure or the other. Further research should be done to confirm these preliminary advantages in a prospective randomized trial with long-term follow-up.

Abstract
The Iberian Peninsula-the southwestern point of Europe, between the Mediterranean Sea and the Atlantic Ocean-was visited and settled in ancient times by a variety of peoples. Phoenicians, Carthaginians, Celts, Greeks, Romans, Visigoths, and Arabs all left their mark on the peninsula, and their cultures blended together to found, among other things, a rich tradition in medicine and surgery. During the Renaissance, the fluid exchange of technical skills and knowledge with the rest of Europe and the emergence of universities ensured the development of a high level of medical expertise. Today, surgery in Spain is at the forefront of innovations in the field.

Abstract
Laparoscopic splenectomy (LS) has recently been gaining acceptance as an alternative to open splenectomy. However, several aspects, such as learning curve, residual splenic function, and management of large spleens, remain controversial. In this paper we present the analysis of technical details and immediate and late outcome of a consecutive series of 64 cases of splenic disorders approached by laparoscopy. Between Feb-1993 and April-1997, 64 patients with a wide range of splenic disorders were treated by laparoscopy, and prospectively recorded. Age, body mass index, operative time, number of trocars, perioperative transfusion, spleen weight, conversion rate, mode of spleen retrieval (bag or accessory incision), postoperative analgesia, stay and morbidity were analyzed. Late failures after LS were reevaluated with 99mTc-heat-damaged red blood cells scintigraphy and CT. LS was performed in 61 patients, and two cases with splenic cyst and one splenic artery aneurysm received a laparoscopic partial cystectomy and aneurysmectomy. LS was performed through an anterior approach in 12 patients and laterally in 49. Conversion rate was 6.5%. Accessory spleens were found in 7 patients (7/61, 11.5%). Morbidity was 16%. There was no correlation between the weight of the spleen, platelet count or obesity with operative time. A lateral approach was associated with a decrease in operative time (p < 0.002), postoperative stay (p < 0.001), transfusion (p < 0.04) and number of trocars (p < 0.001). Operative time was significantly longer in large spleens (> 1000 gr) (p < 0.001). However, there were no differences in transfusion rate, stay, morbidity or conversion rate. After a follow up of 12 m, 10 patients revealed a low platelet count. Scintigraphy showed residual splenic tissue in 3 (ITP). A wide range of splenic disorders can be treated by laparoscopy, including enlarged spleens. This technique should be continually audited, but initial results reflect the approach's safety and advantages provided that great technical care is taken and an exhaustive search for accessory spleens is conducted.

Abstract
Port-site metastasis has been an unexpected finding after laparoscopic surgery in gastrointestinal cancer patients. No clear explanation exists for this phenomenom. The aims of this study were to evaluate the dissemination pattern in an experimental model of hepatocarcinoma in the rat and summarize current knowledge about the risks and the results of experimental studies on cancer dissemination during laparoscopic surgery. NDA-induced hepatocarcinoma was obtained in Sprague-Dawley rats. Tumors were manipulated during laparoscopy (group 1, n = 11) or laparotomy (group 2, n = 12). A Medline review of all experimental studies about the risk of cancer dissemination during laparoscopic surgery was undertaken. Both models were associated with implants in parietal wounds [1/11 in group 1 (9%) vs. 1/12 in group 2 (8%), p = NS]. Analysis of the current literature confirms that laparoscopy is associated with abdominal cell mobilization, and cells can be recovered in trocars, filtered exhaust gas, and instruments. Postoperative immunosuppression, the biologic aggressiveness of the tumor, and the gas used for laparoscopy also influence tumoral growth. Port-site metastases are secondary to multiple factors, including the technical skill of the surgeon, the biologic properties of the tumors, and local environmental aspects. Undoubtedly, laparoscopy can help disseminate aggressive tumors and should be reserved for diagnostic and staging procedures or for treatment of low-grade malignant tumors. Therapeutic resection, especially of colon cancer, should be restricted to prospective and randomized trials until there are enough hard data to rule out the clinical importance of this potentially severe complication.

Abstract
OBJECTIVE To document the existence of residual splenic function after laparoscopic splenectomy in a series of 48 patients. DESIGN A noncomparative descriptive case series. SETTING A tertiary care center. PATIENTS A series of 9 patients without clinical improvement after laparoscopic splenectomy of 48 consecutive patients undergoing laparoscopic splenectomy for several hematologic disorders after a mean follow-up of 16 months (range, 1-40 months). INTERVENTIONS A computed tomographic scan and technetium Tc 99m sodium pertechnetate heat-damaged red blood cell scintigraphy were performed for patients with partial (platelet count <100x10(9)/L) or total (platelet count <50x10(9)/L) failure of improvement. MAIN OUTCOME MEASURE Evidence of residual splenic tissue by image diagnosis. RESULTS The condition of 9 of the 48 patients failed to improve after laparoscopic splenectomy. Six patients experienced a total failure of improvement and 3 experienced a partial failure of improvement (1 patient had human immunodeficiency virus-related thrombocytopenia and 8 had idiopathic thrombocytopenic purpura). Three patients had residual splenic function, which was revealed by scintigraphy. The results of a computed tomographic scan showed an accessory spleen in one patient and splenic implants in splenic fossa in another patient. CONCLUSION Laparoscopic splenectomy has a promising role in the management of hematologic diseases requiring splenectomy, but it requires exquisite care to avoid parenchymal rupture and cell spillage and to avoid leaving accessory spleens, which can lead to the failure of surgical treatment.

Abstract
BACKGROUND Mirizzi's syndrome (MS) is an unusual cause of obstructive jaundice. It can mimic bile duct cancer, and the role of laparoscopic surgery is not well defined. The aim of this paper is to report five cases and describe the pitfalls encountered in its diagnosis and treatment with a laparoscopic approach. METHODS From January 1992 to January 1996, five cases of MS out of 560 patients with gallstones prospectively treated and recorded were found (0.9%). RESULTS There were two men and three women, (mean age: 54 years [30-93]). In one case diagnosis of bile duct carcinoma was established but surgery revealed MS. Four cases were approached by laparoscopy, but all of them were converted: in two, due to a distorted anatomy, in a third due in the difficulty of visualizing the distal end of the bile duct, and in the last case due to the impossibility of retrieving the stones. All were treated with a cholecochorrhaphy over a T tube, except one, in which a hepaticojejunostomy was performed. Morbidity and mortality were nil, and they remain asymptomatic after a mean follow-up of 19 months (3-36). CONCLUSIONS MS constitutes an important laparoscopic challenge, both to clearance of duct stones and to the proper reconstruction of the biliary duct. A prudent policy is to perform a dissection trial and convert if local conditions are not clear for an experienced laparoscopic surgeon.

Abstract
Laparoscopic splenectomy is a feasible and safe technique in the hands of skilled laparoscopic surgeons. The special characteristics of the spleen, a fragile solid organ with a rich vascularization, pose a number of technical questions (patient position, organ mobilization and retrieval) which have been successfully resolved during the last few years and permit the advantages of laparoscopic surgery to become available to patients that need splenectomy.

Abstract
BACKGROUND The best approach to bile duct stones in high-risk patients is controversial. We showed in a randomized trial that open surgery had a morbi-mortality similar to that of endoscopic sphincterotomy alone (ES) and less late biliary complications. The aim of this study was to evaluate a minimally invasive approach to duct stones in high-risk patients compared with open surgery or ES alone. METHODS Sixty high-risk patients (mean age 80 years) suspected of duct stones were treated by ES + laparoscopic cholecystectomy (LC). High-risk factors were: age > 70 years, Goldman cardiac index > 13, chronic pulmonary disease, liver cirrhosis, neurologic deficit, and severe obesity. RESULTS ERCP success was 87%. Duct stones were found in 75%. LC succeeded in 92%. Post-LC stay was 4 days. Overall morbidity was 19% and mortality was 3%. Recurrent symptoms (mean follow-up: 9 months) was 3.6%. When compared with open surgery or ES alone, ES + LC had a similar morbi-mortality, but shorter postop stay (p < 0.001). Late symptoms appeared in 20% after ES alone vs 4% after open surgery or ES plus LC (p < 0.04). CONCLUSIONS Combined ES + LC is an effective alternative to open surgery or ES alone for treatment of duct stones in high-risk patients.
