Right colectomy: value of the totally laparoscopic approach.

UNLABELLED: The role of laparoscopy for right colectomy remains controversial - largely because of a lack of standardization of the operative procedure, including a diversity of techniques including laparoscopy-assisted cases with extra-corporeal anastomosis and totally laparoscopic procedures with intra-corporeal anastomosis. METHODS: The charts of all patients who underwent right colectomy by a totally laparoscopic approach in our service since 2004 were reviewed and pre-, intra-, and postoperative data were collected. RESULTS: Eighty-two patients underwent totally laparoscopic right colectomy; of these, 32 had a BMI greater than 20 kg/m2 (39%). The mean operative duration was 113 minutes. In most cases, the operative specimen was extracted through a supra-pubic Pfannenstiel incision measuring 4-6 cm in length. Three cases were converted to a laparoscopy-assisted technique (in order to control the ileo-cecal vascular pedicle because of extensive nodal invasion in two cases, and to evaluate a hepatic flexure polyp in the third case). Overall morbidity was 29.3% and parietal morbidity was only 9.8%; there was no difference in morbidity between obese patients (BMI>30 kg/m2) and non-obese patients (BMI<30 kg/m2). The mean duration of hospitalization was 9 days and two patients developed ventral hernia in the extraction incision in long-term follow-up. CONCLUSION: These satisfactory results show that the totally laparoscopic approach to right colectomy is technically feasible and safe, even in obese patients. In addition, the very low rate of parietal complications is an argument in favor of this approach.

Management of acute diverticulitis in a tertiary care institution.

BACKGROUND: Diverticular disease of the left colon is a common disease, mainly in the population over 50 years of age. The surgical management of acute diverticulitis is remains controversial, especially in severe forms. OBJECTIVE: This study aimed to evaluate the results of laparoscopic surgery for diverticular disease in a tertiary care institution with a specialist interest in minimally invasive surgery. DESIGN: All patients who had elective laparoscopic sigmoidectomy for diverticulitis within eight years at University Hospital of Luxembourg were selected from a retrospective database to evaluate laparoscopic benefit in moderate and severe disease. RESULTS: A total of 155 patients were divided in two groups: Moderate Acute Diverticulitis (MAD) and Severe Acute Diverticulitis (SAD) respectively. The short-term outcomes, after laparoscopic sigmoidectomy, were evaluated. There were not important differences between two groups. CONCLUSIONS: The laparoscopic management of diverticular disease after moderate and severe crisis gives same benefits and short-term outcomes are similar. Elective Laparoscopic surgery is actually the standard of care for moderate and severe diverticular disease in our institution.

Transjugular Intrahepatic Portosystemic Shunt and Laparoscopic Colorectal Resection: the ideal minimally-invasive management for the treatment of colorectal cancer in severe cirrhotic patients. A case report and literature review.

Surgical interventions on gastrointestinal tract are often not well tolerated by patients with cirrhosis and severe portal hypertension, impairing their prognosis if suffering from malignant disease. Combining the benefits of two minimally invasive techniques such as Transjugular intrahepatic portosystemic shunt (TIPS) and Laparoscopic Colorectal Resection (LCR), the complications related to surgical intervention might be reduced and thus, it allows patients with liver disease, to undergo a curative intervention. One patient with cirrhosis and portal hypertension diagnosed with a rectal cancer underwent a meticulous preoperative preparation through placement of TIPS before laparoscopic surgery. TIPS placement was performed without intraprocedure complications. The patient was successfully operated by laparoscopic technique 36 days after TIPS placement without intraoperative bleeding or postoperative complications. Our experience, despite being based on one case, allows us to conclude that decompression of portal system by TIPS, already used in open surgery, may be applicable as a preoperative laparoscopic procedure with equally satisfactory results.

Influence of obesity-susceptibility loci (MC4R and INSIG2) on the outcome of weight loss and amelioration of co-morbidity in obese patients treated by a gastric-bypass.

BACKGROUND: Genome-wide association and linkage studies have identified multiple susceptibility loci for obesity. OBJECTIVE: We hypothesized that such loci may affect weight loss and comorbidity amelioration outcomes following a gastric-bypass. DESIGN: A total of 200 obese patients who underwent a gastric bypass surgery were genotyped for single-nucleotide polymorphisms (SNPs) in insulin induced gene 2 (INSIG2) and melanocortin 4 receptor (MC4R) obesity genes. RESULTS: After a follow-up of 18 month, the patients (192) data of weight excess loss (72%) and co-morbidities (Hypertension -62- and Diabetes -39-) were analyzed and compared. 26 Patients with SNP were found (9 MC4R and 17 INSIG2). No significant differences in weight excess loss and amelioration of comorbidities were revealed. CONCLUSIONS: The data suggest no influence of weight excess loss and amelioration of co-morbidities after gastric-bypass by genetic susceptibility.

Laparoscopic liver sectionectomy 2 and 3 (LLS 2 and 3): towards the "gold standard".

BACKGROUND: The purpose of this article is to define the state of the art in laparoscopic liver sectionectomy 2 and 3 (LLS 2 and 3) in order to advance the good option towards the "gold standard". METHODS: Based on a large review of the literature as well as on our personal experience the authors define clearly: the feasibility and the effectiveness of LLS 2 and 3. RESULTS: In this review the conversion rate was <4%, the histological positive margins was <0.8%, and the mortality was inferior to 0.8%. CONCLUSION: The LLS 2 and 3 seem equivalent or perhaps better option compared with the same intervention performed by laparotomy and can be proposed as primary with a grade C recommendation.

Laparoscopic Roux-en-Y gastric bypass versus laparoscopic vertical banded gastroplasty: results of a 2-year follow-up study.

BACKGROUND: The world's epidemic of obesity is responsible for the development of bariatric surgery in recent decades. The number of gastrointestinal surgeries performed annually for severe obesity (BMI > 40 kg/m2) in the United States has increased from about 16,000 in the early 1990s to about 103,000 in 2003. The surgical techniques can be classified as restrictive, malabsorptive, or mixed procedures. This article presents the results for 2 years of bariatric surgery in the authors' minimally invasive center and analyzes the results of the most used surgical techniques with regard to eating habits. METHODS: Between January 2002 and January 2004, the authors attempted operations for morbid obesity in 110 consecutive patients adequately selected by a multidisciplinary obesity unit. This represented 43% of all consultations for morbidly obese patients. The patients were classified as sweet eaters or non-sweet eaters. All sweet eaters underwent gastric bypass. The procedures included 70 Roux-en-Y gastric bypasses, 39 Mason's vertical banded gastroplasties, and 1 combination of vertical gastroplasty with an antireflux procedure. Revision procedures were excluded. RESULTS: The mean age of the patients was 41.36 years (range, 23-67 years), and 72.3% were female. The mean preoperative body mass index was 44.78 kg/m2 (range, 34.75-70.16 kg/m2). The mean operating time was longer for gastric bypass than for the Mason procedure. Three patients required conversion to an open procedure (2.7%). The two operative techniques had the same efficacy in weight reduction. Early complications developed in 11 patients (10%), and late complications occurred in 9 patients (8.1%). The postoperative length of hospital stay averaged 4.4 days (range, 1-47 days; median, 4 days), and was longer in the gastric bypass group. The mortality rate was zero. Data were available 2 years after surgery for 101 of the 110 patients (91%). Most comorbid conditions resolved by 1 year after surgery regardless of the type of operation used. CONCLUSION: With zero mortality and low morbidity, bariatric surgery performed for adequately selected patients is the most effective therapeutic intervention for weight loss and subsequent amelioration or resolution of comorbidities. The patient's eating habits before surgery play an important role in the choice of the operative technique used.

Laparoscopic gastrectomy for gastric adenocarcinoma. Long-term results.

BACKGROUND: The objective of our paper is to report on the long-term results of patients with gastric cancer treated by mini-invasive surgery with "intention-to-treat" laparoscopy. PATIENTS AND METHODS: Between June 1993 and January 2006, 130 patients comprising 94 men and 36 women with gastric adenocarcinoma were prospectively selected by two surgical teams in three hospitals based on a prior agreement (CHU Charleroi, Belgium, Centre Hospitalier de Luxembourg and Zumárraga Hospital, Spain). Patients with adenocarcinoma of the cardia were excluded. Mean age of patients was 68 years (range, 37-85 years). RESULTS: Post-operative mortality within 60 days of operation was 6 patients; 109 patients were therefore properly followed up for an average of 49 months (range, 2-153 months).Average survival time for 10 non-resected patients was 4.5 months. Average survival rate for all 14 palliatively resected patients was 6.9 months. Actuarial 5-year survival rate for R0-type surgery was 35%. Global actuarial 5-year survival rate after resective surgery was 31%. CONCLUSIONS: Laparoscopic gastrectomy with any kind of lymphadenectomy is a major but safe operation with acceptable mortality and morbility rates in patients with advanced gastric cancer, usually in poor general condition. Laparoscopic gastrectomy for locally advanced cancers is equivalent to laparotomy as far as long-term oncological results are concerned.

Present state of the Mini-Invasive Surgery (MIS) in esophageal and gastric cancer.

The purpose of this review is to stress the role of the Mini-Invasive Surgery (MIS) in the treatment of the esophagogastric malignant illnesses, supporting ourselves on the most relevant publications of the literature as well as on our own experience in this subject. In short, although no randomised prospective study has proven the MIS advantages in relation to the traditional surgery in the esophagectomy due to cancer, some authors preferently indicate this approach to selected and informed enough patients, who present the following: - High grade dysplasia, preferently choosing from laparoscopic transhiatal esophagectomy (LTE). - Carcinoma in situ, preferently choosing the LTE vs thoracoscopy. - Esophageal tumour locally advanced, in resectable patients with contraindication for a thoracotomy or, in initially non-resectable patients with tumoral reduction after neo-adjuvant chemo-radiotherapy. The arguments given by the authors are the postoperative spectacular improvement in relation to the comfort and quality of life and, the absence of oncological negative effects in the long-term followup. Concerning gastric cancer, the MIS, as exeresis surgical tool in the so-called <> gastric forms, is such a definite and oncological approach as the traditional approach, and superior to this as far as quality of life is concerned. When the MIS is used for treating locally advanced forms of gastric cancer, it is as safe as the laparotomic way and it seems to obtain the same oncological outcomes in the long-term.

Long-term results of laparoscopic extended surgery in advanced gastric cancer: a series of 101 patients.

BACKGROUND/AIMS: The objective of our paper is to report on the remote results of patients with gastric cancer treated by mini-invasive surgery as a surgical tool with the "intention to treat with laparoscopy". METHODOLOGY: Between June 1993 and January 2004, 101 patients comprising 72 men and 29 women with gastric adenocarcinoma were prospectively selected by two hospitals based on prior agreement (the CHU Charleroi, Belgium, and Zumárraga Hospital, the Basque Country, Spain). Patients with adenocarcinoma of the cardia were excluded. Average age of the patients was 67 (37-83). RESULTS: Postoperative mortality within 60 days of operation was of 5 patients; 87 patients were therefore properly followed-up for an average of 41 months (7-129). Average survival time for 10 non-resected patients was 4.5 months. Average survival rate of the 10 palliatively resected patients was 7.1 months. Actuarial 5-year survival rate RO-type surgery was 34%. The global actuarial 5-year survival rate after resective surgery was 29%. CONCLUSIONS: Laparoscopic gastrectomy with any kind of lymphadenectomy is a heavy but safe operation, and produces acceptable mortality and morbidity rates in patients with advanced gastric cancer in a general poor condition. Laparoscopic gastrectomies for locally advanced cancers are equivalent to those reported by laparotomy as far as long-term oncological results are concerned.

[Laparoscopic surgery of gastric cancer]. / Cirugía laparoscópica del cáncer gástrico.

INTRODUCTION: The present state of minimally invasive surgery in gastric cancer is reviewed and its technical aspects are detailed. PATIENTS AND METHOD: The authors provide their personal experience in a non-randomized prospective study, in two different settings (the CHU Charleroi, Belgium and the Hospital of Zumárraga, the Basque Country, Spain) carried out between June 1993 and January 2004. In this study involving 101 patients with gastric adenocarcinoma, the mini-invasive laparoscopic approach was employed as a surgical tool with the "aim of treatment by laparoscopy". The average age of the patients was 67 years (37-83). RESULTS: Postoperativemortality after 60 days was 5 patients; 87 patients were subjected to an oncological follow-up averaging 41 months (7-129). The average of survival observed in the 10 non-resected patients was 4.5 months. The average of survival observed in the 10 patients subjected to a palliative resection was 7.1 months. The actuarial survival after 5 years observed following type RO exeresis was 34%. The 5-years actuarial survival of the resected patients was 29%. CONCLUSIONS: Laparoscopic gastrectomy associated with any type of lymphadenectomy is a significant but safe intervention, with acceptable rates of morbidity and mortality in patients with advanced gastric cancer, who frequently present a bad general status. The long term oncological results are similar to those obtained via laparotomy. More prospective studies are needed that evaluate the results of this approach, both its short-term benefits and the long range oncological result.

Laparoscopic liver resection of benign liver tumors.

OBJECTIVE: The objective of this study was to assess the feasibility, safety, and outcome of laparoscopic liver resection for benign liver tumors in a multicenter setting. BACKGROUND: Despite restrictive, tailored indications for resection in benign liver tumors, an increasing number of articles have been published concerning laparoscopic liver resection of these tumors. METHODS: A retrospective study was performed in 18 surgical centres in Europe regarding their experience with laparoscopic resection of benign liver tumors. Detailed standardized questionnaires were used that focused on patient's characteristics, clinical data, type and characteristics of the tumor, technical details of the operation, and early and late clinical outcome. RESULTS: From March 1992 to September 2000, 87 patients suffering from benign liver tumor were included in this study: 48 patients with focal nodular hyperplasia (55%), 17 patients with liver cell adenoma (21%), 13 patients with hemangioma (15%), 3 patients with hamartoma (3%), 3 patients with hydatid liver cysts (3%), 2 patients with adult polycystic liver disease (APLD) (2%), and 1 patient with liver cystadenoma (1%). The mean size of the tumor was 6 cm, and 95% of the tumors were located in the left liver lobe or in the anterior segments of the right liver. Liver procedures included 38 wedge resections, 25 segmentectomies, 21 bisegmentectomies (including 20 left lateral segmentectomies), and 3 major hepatectomies. There were 9 conversions to an open approach (10%) due to bleeding in 45% of the patients. Five patients (6%) received autologous blood transfusion. There was no postoperative mortality, and the postoperative complication rate was low (5%). The mean postoperative hospital stay was 5 days (range, 2-13 days). At a mean follow-up of 13 months (median, 10 months; range, 2-58 months), all patients are alive without disease recurrence, except for the 2 patients with APLD. CONCLUSIONS: Laparoscopic resection of benign liver tumors is feasible and safe for selected patients with small tumors located in the left lateral segments or in the anterior segments of the right liver. Despite the use of a laparoscopic approach, selective indications for resection of benign liver tumors should remain unchanged. When performed by expert liver and laparoscopic surgeons in selected patients and tumors, laparoscopic resection of benign liver tumor is a promising technique.

Is there a place for laparoscopy in management of postcholecystectomy biliary injuries?

Despite its minimal invasiveness, laparoscopic cholecystectomy (LC) carries unquestionably higher morbidity and mortality rates when compared with the open counterpart (OC). Among the iatrogenic injuries, biliary tract lesions are the most clinically relevant because of their potential for patient's disability and long-term sequelae. No universal agreement exists for classifying these lesions, but numerous authors have advocated a distinction between bile leaks and bile injuries. Even if not entirely correct, bile leaks refer to fistulas from minor ducts in continuity with the major ductal system or from accessory ducts (as the duct of Luschka). Biliary injuries are major complications consisting of leaks, strictures, transection, or ligation of major bile ducts. While bile leaks are typically treated by percutaneous and/or endoscopic drainage and stenting, biliary injuries often require a combined radiology-assisted and endoscopic approach or even conventional surgery. The role of laparoscopy in the management algorithm of biliary lesions is still anecdotal. To date, a total of 25 cases of laparoscopic drainage of post-cholecystectomy bilomas have been reported in the literature, whereas there is no mention of laparoscopic primary repair of biliary injuries detected at or after cholecystectomy. The main reasons depend on the excellent results achieved by the ancillary techniques; the emergency settings that accompany more complex biliary lesions; the technical challenges posed by the presence of inflammation, collections, and obscured anatomy; and the potential for malpractice litigation. However, a sound laparoscopic technique and a strict adherence to basic surgical tenets are crucial in order to avoid the incidence of iatrogenic biliary injuries and reduce their still unknown impact on long-term patient disability.

Laparoscopic cholecystectomy for acute cholecystitis in geriatric patients.

Although acute cholecystitis (AC) in many centers is routinely treated by laparoscopic cholecystectomy (LC), the outcome of LC for AC in geriatric patients (75 years or more) remains almost unstudied. All 32 geriatric patients undergoing a cholecystectomy for histologically proven AC in a teaching hospital during a six-year period were studied retrospectively. Median preoperative duration of symptoms was eight days and median preoperative hospital stay was six days. Preoperative ERCP was performed in 22 patients with successful sphincterotomy and common bile duct (CBD) stone retrieval in 11 patients. Overall twelve patients (37%) had CBD stones and 14 patients (44%) had gangrenous cholecystitis at operation. Twenty-seven patients underwent a LC with a conversion rate of 26%, a complication rate of 41% and a mortality rate of 3.7%. Five patients were judged unstable for a laparoscopic approach and underwent a straight open cholecystectomy. Although the latter were at higher risk (higher APACHE II scores), their outcome except for longer intensive care unit stays, was not different from laparoscopically treated patients. Lack of superiority of laparoscopic over open cholecystectomy in the present study seemed due to clinical characteristics of AC in geriatric patients which may lead to late diagnosis and treatment. Preoperative ERCP by further delaying surgery may contribute to loose any potential benefit of an early laparoscopic procedure. The place of preoperative ERCP and the timing of LC in geriatric patients with AC therefore may need to be redefined.

Utility of flow cytometry immunophenotyping for the diagnosis and classification of lymphoma in community hospital clinical needle aspiration/biopsies.

CONTEXT: Flow cytometry immunophenotyping (FC) of needle aspiration/biopsy (NAB) samples has been reported to be useful for the diagnosis and classification of lymphoma in university and cancer center-based settings. Nevertheless, there is no agreement on the utility of these methods. OBJECTIVE: To further define the utility of adjunctive FC of clinical NAB for the diagnosis and classification of lymphoma, and to determine if this approach is practicable in a routine clinical practice setting. SETTING: A community-based hospital. METHODS: Clinical NABs were submitted for adjunctive FC between June 1996 and September 1999 if initial smears were suspicious for lymphoma. Smears and cell block or needle core tissues were routinely processed and paraffin-section immunostains were performed if indicated. The final diagnosis was determined by correlating clinical and pathologic data, and the revised European-American classification criteria were used to subtype lymphomas. RESULTS: Needle aspiration/biopsies from 60 different patients were submitted for FC. Final diagnoses were lymphoma (n = 38), other neoplasm (n = 15), benign (n = 6), or insufficient (n = 1). For 38 lymphomas (20 primary, 18 recurrent), patients ranged in age from 32 to 86 years (mean, 62 years); samples were obtained from the retroperitoneum (n = 11), lymph node (n = 9), abdomen (n = 8), mediastinum (n = 6), or other site (n = 4); and lymphoma subtypes were indolent B-cell (n = 20; 2 small lymphocytic, 14 follicle center, 4 not subtyped), aggressive B-cell (n = 14; 3 mantle cell, 10 large cell, 1 not subtyped), B-cell not further specified (n = 2), or Hodgkin disease (n = 2). For the diagnosis of these lymphomas, FC was necessary in 20 cases, useful in 14 cases, not useful in 2 cases, and misleading in 2 cases. Thirty-two of 36 lymphoma patients with follow-up data received antitumor therapy based on the results of NAB plus FC. CONCLUSIONS: Adjunctive FC of NABs is potentially practicable in a community hospital, is necessary or useful for the diagnosis and subtyping of most B-cell lymphomas, and can help direct lymphoma therapy. Repeated NAB or surgical biopsy is necessary for diagnosis or treatment in some cases.

The current role of laparoscopic surgery in the treatment of benign gastroduodenal diseases.

BACKGROUND/AIMS: The impressive breakthrough in laparoscopic surgery has urged several authors to adopt such an approach in the treatment of both benign and malignant gastric diseases, even though laparoscopic gastric resection has not yet met with widespread enthusiasm. The current work is aimed at illustrating the feasibility and assessing the efficacy of laparoscopic (LGRs) and laparoscopic-assisted (LAGRs) gastric resections in the treatment of non-malignant gastric conditions. METHODOLOGY: As of April 1997, we performed LGRs or LAGRs on a total of 24 patients (M:F = 15:9; mean age: 43 years; range: 19-65 years), among whom 8 presented with chronic gastric ulcer, 4 had benign pyloric stenosis, 8 were affected with recurrent duodenal ulcers no longer amenable to treatment, and 4 with persistent symptomatic biliary reflux. Pre-operatively, all patients underwent blood tests, upper GI endoscopy coupled with biopsy, and barium swallow. Post-operatively, all patients were administered saline solution and water dextrane for the first 5 days; antibiotics (cefuroxim 4 g i.v. daily) and analgesics (paracetamol 6 g i.v. daily) for the first 48 hours. A hydrosoluble swallow was scheduled for the 5th post-operative day. RESULTS: The surgical procedure consisted of a Billroth II distal gastrectomy in 13 cases and total duodenal diversion with Roux-en-Y gastrojejunostomy in 11. Among such patients, 18 underwent a totally laparoscopic procedure, whereas 6 had laparoscopic-assisted gastrectomy, with the use of a Dexterity device in 1 case. The mean duration of the procedure was 150 min (range: 120-200), and blood losses were not remarkable. No intra-operative complication ever occurred. Post-operatively, we observed one case of retrogastric collection and incisional hernia in 1 patient who underwent a laparoscopic-assisted procedure. The abscess was drained percutaneously and hernia conventionally repaired 5 months post-gastrectomy. Post-operative hospital stay was 7 days on the average (range: 5-25). One patient was lost to follow-up. In the remaining cases, no major functional sequelae were observed at a mean follow-up of 19 months (range: 2-41), apart from 2 cases of transient diarrhea. CONCLUSIONS: Laparoscopic surgery appears to be an invaluable tool for the treatment of gastric diseases and LGRs are a valid option in experienced hands and in selected centers, allowing patients to benefit from a less cumbersome hospital stay and fewer functional sequelae. The economic impact of such a practice, however, needs better clarification.

Laparoscopic gastric reduction surgery. Preliminary results of a randomized, prospective trial of laparoscopic vs open vertical banded gastroplasty.

BACKGROUND: The purpose of the current study was to present the preliminary results of a randomized prospective trial comparing laparoscopic and open vertical banded gastroplasty (Mason's procedure). METHODS: From April 1995 to April 1996, 68 patients (9 men and 59 women, mean age, 36 years; ranges, 17-60 years) affected from morbid obesity (mean body weight, 123 kg; range, 89-188 kg; mean body mass index (BMI), 43 kg/m2; range, 37-66 kg/m2) were enrolled in a prospective trial and randomly assigned to a laparoscopic (group A) or open (group B) Mason's gastroplasty. There was no statistically significant difference between the two groups in terms of patient epidemiologic data. The significance level among the data was assessed by means of Fisher's exact test. RESULTS: The success of laparoscopic gastroplasty was 88.2% (30/34). The intervention was significantly longer in the laparoscopic group (150 min vs. 60 min; p = 0.001). No mortality was recorded in the overall population. Intraoperative complications included only one case of gastric bleeding in group A (2.9% vs. 0%; p value not significant [NS]). Early major complications ranged as high as 6.6% and 7.8%, respectively, in groups A and B (p = NS), and included one case of peritonitis and one case of pneumonia in group A, and two cases of peritonitis and one pulmonary embolism in group B. Early minor postoperative complications consisted of wound infections only, observed in one group A patient (3.3%) and four group B patients (10. 8%, p = 0.04). At longer follow-up, incisional hernias occurred in 15.8% (6/38) of patients surgically treated with a conventional approach compared with none among those successfully surgically treated with laparoscopic access (p = 0.04). No statistically significant difference was observed between the two groups regarding the efficacy of the procedure, in terms of decrease in percentage of excess body weight, mean body weight, or mean BMI. CONCLUSIONS: The preliminary results of current study show that the laparoscopic Mason procedure is a time-consuming and technically demanding operation, as effective as its traditional counterpart, but carrying a statistically significant decrease in the incidence of wound infections and incisional hernias.

Minimally invasive surgery for gastric cancer.

BACKGROUND: The use of laparoscopic surgery in the treatment of gastric cancer has not yet met with widespread acceptance; thus, it should be regarded as still in the developmental phase. Nevertheless, the laparoscopic approach appears to have some valuable advantages for the management of gastric cancer patients, and it can be expected to have a dramatic impact on public health expenditures. Herein we present the results of our experience with laparoscopic and laparoscopy-assisted gastrectomies for cancer, and we discuss the role of these procedures in current surgical practice. METHODS: Between June 1993 and November 1997, we performed a total of 13 laparoscopic procedures on 13 patients affected with gastric carcinoma. There were eight male and five female patients with a mean age of 65.4 years (range, 42-78). All patients were staged preoperatively with US and CT scan and required to sign a formal consent. RESULTS: Altogether we performed nine D1 laparoscopic total gastrectomies, seven of which were done with a laparoscopy-assisted approach; three D2 laparoscopy-assisted total gastrectomies, associated in one case with a distal pancreasectomy; and one laparoscopy-assisted distal gastrectomy performed on a morbid obese patient. The preliminary laparoscopic staging allowed for a better definition of tumor extension and identification of undetected hepatic metastases in two patients. The mean duration of the intervention was 240 min. Blood losses were as high as 300 cc on average. We recorded one major intraoperative complication, consisting of an inadvertent injury to the proper hepatic artery, which was successfully repaired by the same laparoscopic route. The postoperative course was uneventful in all patients but one, who died of acute hepatic failure on day 6. At a mean follow-up of 27.5 months, 11 patients are still alive. Two of them have hepatic metastases and nine are disease-free. CONCLUSIONS: Although they remain challenging procedures, laparoscopic gastrectomies appear to be oncologically adequate. We believe that a pure laparoscopic approach should be reserved for low-stage lesions (N0, up to T2), while a combined approach is preferable for locally advanced cancer (N1 or higher, T3 or higher). Much work still needs to be done to establish the optimal strategy in both open and laparoscopic surgery, but laparoscopy can be a valuable tool in the decision-making process for patients affected with gastric malignancies.
