Predictive factors for successful laparoscopic splenectomy in immune thrombocytopenic purpura: study of clinical and laboratory data.
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.

Immediate peritoneal response to bacterial contamination during laparoscopic surgery.
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.

Multimedia article. Laparoscopic treatment of chronic sigmoid volvulus in a young adult.
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.

Long-term outcome after laparoscopic splenectomy related to hematologic diagnosis.
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.

Mid term analysis of safety and quality of life after the laparoscopic repair of paraesophageal hiatal hernia.
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.

Hand-assisted laparoscopic splenectomy (HALS) in cases of splenomegaly: a comparison analysis with conventional laparoscopic splenectomy.
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.

Prospective randomized trial comparing conventional laparoscopic colectomy with hand-assisted laparoscopic colectomy: applicability, immediate clinical outcome, inflammatory response, and cost.
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.

Evaluation of risk of splenosis during laparoscopic splenectomy in rat model.
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).

Laparoscopic surgery of the spleen: state of the art.
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.

Hand-assisted laparoscopic splenectomy.
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.

Complications of laparoscopic splenectomy.
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.

Impact of hematological diagnosis on early and late outcome after laparoscopic splenectomy: an analysis of 111 cases.
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.

Laparoscopic surgery and surgical infection.
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.

Applicability of laparoscopic surgery for colorectal disease.
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.
