RESUMEN
Sclerosing mesenteritis is a rare, idiopatic, usually benign, inflammatory process of the mesenteric adipose tissue. The most common site of involvement is the small bowel mesentery. We present a case of sclerosing mesenteritis of the rectosigmoid colon as a cause of severe abdominal pain, abdominal obstruction, and ischemic colic mucosal lesions. Contrast enema, colonoscopy, angiography, and CT were the imaging modalities used. A 20 cm diameter, fibrotic mass causing extensive compression of rectosigmoid colon was found at laparotomy. Histological examination showed extended fibrosis, inflammatory cells infiltration, lipophages, and granulomas within the mesenteric adipose tissue associated with erosive colitis. Clinical presentation and treatment are discussed.
RESUMEN
BACKGROUND: The treatment of pancreatic cancer is still rudimentary, even in the case of locally limited tumors, because of the high frequency of recurrence due to severe suppression of the anticancer immunity that is further amplified by surgery-induced immunosuppression, evidenced by a decline in lymphocyte numbers during the postoperative period. Previous studies in colorectal cancer demonstrated that surgery-induced lymphocytopenia may be abrogated by a brief preoperative administration of IL-2. MATERIALS AND METHODS: The study included 30 consecutive patients who were randomized to be treated by radical surgery alone as a control group or by a preoperative immunotherapy with IL-2 (12 MIU/day SC for 3 consecutive days) plus surgery. RESULTS: Mean lymphocyte numbers significantly decreased in patients treated with surgery only, whereas it significantly rose in the IL-2-treated group. After a follow-up of 36 months, both the free-from-progression period (FFPP) and the overall survival were significantly higher in patients treated with IL-2. CONCLUSION: These preliminary results suggest that a short-period preoperative immunotherapy with IL-2 is sufficient to modify host tumor interactions in operable pancreatic cancer, with a subsequent abrogation of postoperative lymphocytopenia and a prolongation of FFPP and overall survival time.

A 57-year-old woman presented with fever, vomiting and arthralgia, with a history of rheumatoid arthritis. Laboratory tests showed leucocytes, anaemia and elevation of C-reactive-protein (CRP). Blood cultures were positive for Gram negative bacteria and Streptococcus viridans. Patient underwent abdominal Computed Tomography (CT) scan revealing sigmoid acute diverticulitis with peridiverticular abscesses and thrombophlebitis within the inferior mesenteric and portal veins. She started antibiotic and anticoagulant therapy. After 20 days, a second CT revealed a thrombosis involving the superior mesenteric vein also. After 22 days of therapy the patient was discharged with the resolution of the septic status. Two months after discharge the patient underwent left hemicolectomy for a histopathologically documented diverticulitis with an uneventful postoperative course. This is a description of a rare association of septic thrombosis within the portal, inferior mesenteric and superior mesenteric veins during acute sigmoid diverticulitis with abdominal abscesses. Our therapeutic strategy was a first line medical approach and delayed surgery.

BACKGROUND: Bleeding is the main complication and cause of conversion during laparoscopic splenectomy (LS). We present the advantages of the LigaSure vessel sealing system added to the lateral approach for achieving safe vascular control. METHODS: We performed 63 consecutive LS in a 3-year period using LigaSure in two affiliated university hospitals. We employed a right semilateral position technique with dissection of the spleen and vessel sealing using LigaSure. Forty-two patients had benign hematological disease, 19 had malignant disease, and two had splenic cysts. RESULTS: A total of 58 LS were completed with five conversions due to hilar bleeding (three cases), difficult dissection (one), and massive splenomegaly (one). In all but five patients, blood loss was less than 100 ml. No transfusions were needed. There were five postoperative complications: portal thrombosis (one case), hemoperitoneum (two), surgical wound infection (one), and pleural effusion (one). CONCLUSIONS: The use of LigaSure, and the semilateral position, results in a gain of time and safety. Furthermore, average intraoperative bleeding is very low.

AIM: Intestinal obstruction is a frequent event in patients affected by ovarian carcinoma. Little data on repeat palliative surgery for recurrent bowel obstruction are available. The aim of this study was to analyze postoperative and long term outcomes of ovarian cancer patients who underwent reoperation for recurrent intestinal obstruction. METHODS: We retrospectively evaluated the records of these patients treated at our Department between 1992 and 2002. RESULTS: Nine women with a mean age of 56 years (range 37-72) were identified. All patients had undergone previous abdominal surgery for bowel obstruction from ovarian cancer. All patients underwent exploratory laparotomy. In 4 patients (Group A) because of advanced disease, only exploratory surgery was carried out. A surgical correction was achieved in the other 5 patients (Group B), but only 3 patients had a successful palliation, defined as the ability to tolerate an oral intake for at least 60 days postoperatively. Postoperative mortality was nil, morbidity was 44.4%; particularly 2 patients developed an enterocutaneous fistula. Mean survival of Group A and B patients were 36.7 and 96.2 days respectively. The 3 successful palliated patients died of disease after 3.5, 4 and 5 months, in 2 cases for recurrent bowel obstruction. CONCLUSIONS: Repeat surgery for recurrent bowel obstruction in advanced ovarian carcinoma may achieve successful palliation in few cases and is associated with high postoperative morbidity and limited survival. In these patients non surgical approaches based on medical treatment, percutaneous endoscopic gastrostomy and stent placement should be considered.

Cell-mediated immunodeficiency, with Total and T lymphocytes count decrease, is well established in cancer patients and it predicts a poor prognosis and poor survival rates. Furthermore, major surgery induces a transient immunodeficiency, too. Nevertheless, cell-mediated immunity in pancreatic cancer, which has a very poor prognosis, has not been completely outlined. Aim of this study is to evaluate the cell-mediated IL-2 dependent immune status in operable pancreatic cancer patients and to compare it with other gastrointestinal tumors. One hundred and twenty-one cancer patients (22 pancreatic, 48 gastric and 51 colorectal), with a median age of 66 years (range 42-83), 55 males and 66 females, were enrolled. Total lymphocyte count and lymphocytes subset (T helper count - CD4+) were assessed preoperatively and on the 14th and 50th postoperative day. Results obtained were compared between the groups and related to nodal involvement (N0 versus N+). Colorectal and gastric cancer patients showed quantitative lymphocyte deficiency at baseline in 29% and 41% of cases, respectively. Fourteen days after surgery values below normal range were found in 44% and 54% (Total) and 53% and 67% (T helper), respectively. Recovery of postoperative surgery-related lymphocytopenia occurred late only in patients with normal count at baseline. According to regional nodal involvement (pN0/N+) T helper deficiency was significantly more frequent in patients with nodal involvement than in patients without. In pancreatic cancer, percentage of immunodepressed patients at baseline was higher compared to the other two groups (71%). Lymphocyte count was significantly different between pancreatic and gastric/colorectal cancer, reaching a statistical significance at baseline and on the 14th and 50th postoperative day. No differences of T helper deficiency were noted according to nodal involvement (N0 versus N+) neither at baseline nor in the postoperative period. In conclusion, the degree of immunosuppression varies among different tumor types: since initial stages of disease, immunodepression was significantly greater in pancreatic cancer which should be considered always a systemic disease even in early stages and indipendently from the nodal involvement and from tumor load.

BACKGROUND: Gastrointestinal carcinoid tumors are rare and little is known about factors related to prognosis in patients with carcinoid disease. Aim of this study is to determine the impact of clinical presentation variables on the management and survival. METHODS: We have evaluated 31 consecutive patients with gastrointestinal carcinoid tu-mours who underwent surgical intervention at the I Department of Surgery of Milano-Bicocca University over 15 years (1985-1999). Tumor distribution, hormone production, prognostic factors and survival were analysed. RESULTS: Carcinoid syndrome was the only clinical pattern diagnostic of carcinoid tumour. Most common symptoms were abdominal pain (64%), nausea and vomiting (48%). High levels of urinary 5-hydroxyindolacetic acid were significantly associated with carcinoid syndrome and metastatic disease. Tumor size, depth and gender were significant predictors of metastases. Age, gender, tumor size, metastatic spread and location were statistically significant predictors of death. CONCLUSIONS: Clinical presentation was non specific except for those patients affected by carcinoid syndrome. Ten years overall survival was 43%, with 52% metastatic spread incidence. The extent of surgical resection should be modulated on patient related risk factors. Poor prognostic factors affecting survival were: age, gender, metastatic disease, depth of invasion and tumour size.

AIM: In advanced cancer patients a cell-mediated immunological impairment, both at baseline and during postoperative period, is often found and is associated with poor prognosis. Cortisol is strictly involved in the response to major surgical stress, is an immunosuppressor and causes a redistribution of immunological population cells in different tissues. The aim of the study was to verify serum levels and circadian rhythm of cortisol in patients with colorectal cancer at baseline before surgery and in the postoperative period, and relate it to the immune status. METHODS: In 21 patients with colorectal cancer undergoing surgery we evaluated the assessment of total lymphocytes, CD4+, cortisolemia, circadian rhythm of cortisol (11 p.m. and 8 a.m.) at baseline and in 3(rd) and 7(th) postoperative days. RESULTS: Increase of cortisolemia, as decrease of total and CD4+ lymphocytes in the postoperative period versus baseline was statistically significant. Patients with an altered circadian rhythm were 47% and 36% at 3rd and 7th postoperative days, respectively. At baseline 19% of patients had an altered cortisol circadian rhythm and it was more frequent in patients with nodal involvement (p<0.05) and with metastasis (p<0.01). No relations between lymphocytopenia and alteration of cortisolemia and cortisol circadian rhythm were found, either at baseline or postoperatively (p<0.05). CONCLUSION: Lymphocytopenia in cancer patients seems not to be associated with cortisol level and circadian rhythm alteration, either at baseline or after surgical stress. An impairment of circadian rhythm of cortisol was found at baseline in 19% of patients. It was significantly associated with the presence of metastatic disease.

Cell-mediated immunodeficiency is known to occur in advanced cancer patients, but it is less characterized in earlier stages. Pre-existing immunodeficiency may impair the recovery of postoperative lymphocytopenia, occurring generally within 8-14 days after surgical stress. This study was aimed to verify whether immunodeficiency exists in patients with operable gastric adenocarcinoma and whether radical surgery may restore a count of peripheral blood T helper cells (CD4) and CD4/CD8 ratio within physiological normal values in the late postoperative period. Thirty-five consecutive patients (M/F 18/17; mean age 67 years, range 42-82) with histologically proven gastric adenocarcinoma, undergoing surgery with radical intent, were studied. Assessment of total lymphocyte count and lymphocyte subsets was performed by FAC scan at baseline, then postoperatively 14 and 50 days after surgery. Normal reference values were according to CDC criteria for HIV immunodeficiency (total lymphocyte > 1500/mmc; CD4 cells > 500/mmc; CD4/CD8 > 1.2). Surgical interventions, including D2 locoregional lymphadenectomy, were as follows: 19 Roux Y total gastrectomies; 3 Roux Y subtotal gastrectomies and 13 Billroth II subtotal gastrectomies. Pathological nodal staging was pN0 in 18 and pN+ in 17 cases. Hystotype was intestinal in 14 patients, diffuse in 14 and unclassifiable in 7. Grading was G1 n = 7; G2 n = 7; G3 n = 21. Lymphocyte immunodeficiency was found at baseline in 41% of patients and at 14 days after surgery in 67% of patients. Recovery of postoperative surgery-induced lymphocytopenia occurred on the 50th day only in those patients with normal values at baseline (59%). CD4 deficiency was significantly more frequent in pN+ vs. pN0 patients, either at baseline (p < 0.001 ), on the 14th day (p < 0.02) and on the 50th day (p < 0.007) postoperatively. Cancer-related CD4 deficiency was a frequent finding in our consecutive series of gastric cancer patients; this systemic immune impairment was not restored after complete tumor removal, even in late postoperative period (50th day ). Further studies on a larger number of cases may confirm the prognostic value of lymphocyte count in early gastric cancer stages, and to verify whether early and late postoperative immunodeficiency may be prevented by IL-2 administration.

BACKGROUND: Intraoperative bleeding is the main complication and main cause of conversion during laparoscopic splenectomy (LS). We present the advantages of the use of the Ligasure Vessel Sealing System added to lateral approach for achieving a safe vascular control. METHODS: Ligasure is an energy-based device which works applying a precise amount of bipolar energy and pressure to the tissue, achieving a permanent seal. We have performed a total of 35 LS in a 5-year period using different approaches and methods of dissection, including the anterior approach, monopolar coagulation, clips, endostaplers, and ultrasonic shears. In the last 10 patients (4 males and 6 females, mean age 24 yr) we employed a technique with 4 trocars, right semilateral position associated with the entire dissection of the spleen and vessels sealing (lower pole vessels, main vascular pedicles, short gastric vessels) performed with Ligasure. Six had thrombocytopenic idiopatic purpura (ITP), 2 hereditary spherocytosis and one each b-thalassemia and hemolytic anemia. RESULTS: Nine LS were completed with one (10%) conversion because of hilar bleeding due to accidental injury with Ligasure. The average splenic weight was 485 g (range 265-1800), with an average diameter of 16 cm (range 12-25). In all but one patients (the converted one) the intraoperative blood loss was less than 100 mL (range 50-100 mL, average 80 mL). No blood transfusion were needed. The average operative time was 120 min (range 90-165), including 2 patients undergoing combined laparoscopic cholecystectomy. There was no mortality, with one (10%) postoperative complication (thrombosis of the spleno-portal axis), treated with a conservative approach. The average postoperative hospital stay was 3.5 days (range 3-6). CONCLUSIONS: The use of Ligasure, associated with the lateral position, results in a gain of time and safety. Furthermore, the average intraoperative bleeding of this series is very low.

Vertical banded gastroplasty, reported by Mason in 1982, is an effective method to control pathologic obesity (BMI>40 kg/m2). With the widespread of this procedure and the introduction of laparoscopic approach several complications are described in literature: gastroesophageal reflux, esophagitis, gastritis, gastric bleeding and perforations, prolonged vomit, dislocation of gastric ring, cholelithiasis, gastric fistulas, gastric stomal stenosis, dehiscence of vertical stomach staple line. From 2 to 10% of patients are reoperated because of inefficacy of treatment or short and long-term complications. Morbidity and mortality associated to reoperations are still high and it is difficult to identify criteria for an appropriate revision procedure. This can occur through endoscopy, laparotomy or laparoscopy, depending on clinical and radiologic feature. Dehiscence of vertical stomach staple line, observed in 10-20% of cases, even if asymptomatic, can lead to bad complications such as fistulas, peritonitis and sepsis. The case of a young woman, who underwent a vertical banded gastroplasty for pathologic obesity (117 kg, h 167 cm, BMI 42/m2) and subsequent laparotomies in the attempt to correct vertical staple line dehiscence, is reported. The patient came to our observation in a septic shock caused by peritonitis and ARDS and a total gastrectomy with Roux-en-Y esophago-jejunostomy was performed.

Gallbladder cancer is a relatively uncommon malignancy. Its presentation is similar to that of gallstone disease and sometimes with non-specific symptoms. Laparoscopic cholecystectomy has become the method of choice for removing the gallbladder in most benign conditions. Occasionally, unsuspected gallbladder carcinoma is encountered in association with laparoscopic cholecystectomy. Overall gallbladder cancers have a poor prognosis, despite surgery or adjuvant therapies. However, in selected cases, a favourable outcome can be expected and the less favourable predicted outcome can be improved. Management of patients with gallbladder cancer in different situations is discussed: gallbladder cancer noted post-operatively on final pathology, gallbladder cancer noted after removal of the gallbladder and opening of the specimen at the time of surgery, difficulty encountered at the time of dissection and resultant suspicion of gallbladder cancer, and diagnosis of extensive disease at initial placement of the laparoscope.

Laparoscopic splenectomy (LS) is gaining wide acceptance as a safe, effective alternative to open splenectomy (OS) in the treatment of hematologic disorders in adult and pediatric patients, with low conversion rates and complications. The aim of this retrospective case-control study was to compare two cohorts of patients, with similar characteristics, who underwent OS or LS in a single institution. The medical records of the initial 20 consecutive patients who underwent LS were reviewed and compared with a control group of 28 patients undergoing OS, matched for age, gender, diagnosis, splenic size and weight, and American Society of Anesthesiologists score. Data were collected regarding operative time, blood loss, blood transfusions, pathologic findings, accessory spleen detection, complications, ileus duration, and postoperative hospital stay. Nineteen patients underwent attempted LS. One procedure (5%) was converted to OS for uncontrolled hilar bleeding. Accessory spleens were detected in two cases in the LS group compared with four cases in the OS group (14%). Mean operative time was 165 minutes (range: 100-240 minutes) for LS and 114 minutes (75-180 minutes) for OS (P < 0.001). In the LS group a regular diet was tolerated 36 hours (range: 24-48 hours) after surgery compared with 72 hours (range: 48-96 hours) for the OS group (P < 0.001), and mean postoperative hospital stay was 4.1 days (range: 3-8 days) for LS, compared with 8.1 days (range: 5-12 days) for OS (P < 0.001). No differences were observed in blood loss, complication rates, or transfusion requirements. Compared with OS, LS requires more operative time (showing a learning curve), is comparable in blood loss, transfusion requirements, complication rates, and detection of accessory spleens and appears to be superior in terms of return of bowel function and hospital stay.

BACKGROUND: Laparoscopic cholecystectomy is now worldwide considered the elective therapy for biliary lithiasis. Morbidity, mortality and conversion rates reported in the literature are assessed between 1 and 6%, 0 and 0.9%, 3.6 and 7.2% respectively. Data on personal experience with 1019 attempted laparoscopic cholecystectomy are reported. METHODS: In the period between 1991 and 1997 1019 laparoscopic cholecystectomy were performed. Patients were 361 males and 658 females (ratio M:F 1:2), with an average age of 51 years (range 5-85). Indications were: 647 symptomatic cholelithiasis, 28 hydrops, 121 empyemas, 76 cholecystocholedocolithiasis and 13 alithiasic cholecystopathy. RESULTS: Conversion was necessary in 61 cases, with a conversion rate of 6%. Mean duration of surgery was 65 minutes (range 30-240) with a mean hospital stay of 2.1 days (range 1-10). No deaths occurred in our series, with a morbidity rate of 1.8% (18 cases, 7 major and 11 minor). Only 1 case of bile duct injury (0.1%) is reported. CONCLUSIONS: In consideration of low conversion rate, low early and late morbidity, absence of bile duct injury, advantages for the patient and the opportunity of evolution of this surgery, laparoscopic cholecystectomy can be considered the standard treatment for biliary lithiasis.

BACKGROUND: Gallbladder cancer (GC) is reported in 1.5-3% of cholecystectomies. Since the introduction of laparoscopic surgery, cholecystectomies have increased and occult GC may therefore be more frequent. METHODS: Here we conduct a retrospective study on a series of 1200 LC performed between January 1991 and December 1998 at our Institution, to determine whether there was an increase in GC. We also evaluated the risk factors for this outcome and the possibilities of treatment, in case of unsuspected GC discovered after LC at histological examination. Seven cases of GC undiagnosed before surgery (0.6% of the study population) were submitted to LC (against 0.3% GC discovered after open surgery). The clinical course depended on the histopathologic stage of the cancer. RESULTS: After a median follow-up of 18 months (range 12-48), 2 pT1 patients were alive and well, 2 pT2 patients were alive and disease free (in 1 case after a surgical removal of a trocar site metastasis appeared 6 months after LC). The other 3 patients died, 2 (1 pT2 and 1 pT3) after an additional resection of the liver bed with lymph node dissection, due to peritoneal dissemination of the disease. In 2 cases we found a gallbladder polyp pre and intraoperatively, which proved to be a carcinoma. CONCLUSIONS: Undiagnosed GC is on the increase with the introduction of LC. Polypoid lesions of the gallbladder, age > 70 years: a long history of stones and a thickened gallbladder wall all represent significant risk factors. If one or more is present, examination of the gallbladder and a frozen section are recommended.

BACKGROUND: Inguinal hernia repair with prolene mesh according to Lichtenstein "tension free" technique has gained great acceptance worldwide, showing efficacy to consolidate the posterior wall of the inguinal canal and to reduce recurrence risk because of tension on suture lines and postoperative pain. Personal experience of 692 hernias treated with this technique is reported. METHODS: From January 1989 to December 1997, 692 patients were treated according to Lichtenstein at the General Surgery Department of the San Gerardo Hospital. Mean age was 60 years (range 18-88) with a male: female ratio of 13:1. Surgery was performed under local anesthesia in 185 cases, under epidural anesthesia in 317 and under general anesthesia in 190. Hernia was primitive in 647 cases (411 obliquo-external and 236 direct), while in 45 patients it was a recurrent hernia. In this series, 619 patients had monolateral inguinal hernia, while 73 had a bilateral one. In 40 cases hernia was incarcerated and in 8 strangulated. RESULTS: Mean hospital stay was 2.3 days (range 1-8). Eleven (1.6%) early complications, were observed, with one periprosthetic infection which resolved after patch removal, 3 hematomas, 2 seromas and 2 wound infections. Furthermore, there were 32 (4.6%) late complications with only one recurrence (0.14%) in this series and 25 cases of persistent nerve irritation. CONCLUSIONS: The results obtained with Lichtenstein "tension free" repairs of inguinal hernias confirmed this technique as easy to perform, also under local anesthesia, and associated with low rates of complications and without recurrences.

BACKGROUND: Laparoscopic treatment of common bile duct (CBD) stones is gaining great acceptance worldwide, but actually it requires skills and technologies too expensive for a great part of general surgeons. So endoscopic removal of CBD stones before cholecystectomy is usually performed. Since 1991 in our department we started a policy of selective preoperative cholangiopancreatography (ERCP) in patients suspected for choledocholithiasis and waiting for laparoscopic cholecystectomy. METHODS: A retrospective study has been made on a population of 1100 patients who underwent elective laparoscopic cholecystectomy in the period between January 1991 and December 1997. They were 391 male and 719 female with a mean age of 52 years, 126 of whom (11.5%) were selected to have ERCP preoperatively because they had clinical, biochemical and ultrasound signs of the presence of common bile duct stones (CBDS). RESULTS: Successful cannulation of the CBD was achieved in 124 cases (98.4%), with failures due to ampullary diverticula. In 7 cases (5.5%) a precut was necessary to obtain cannulation. Sphincterotomy was performed in 113 patients (89.7%). In 93 patients (73.8%) stones were found (87 macrolithiasis and 6 microlithiasis); in 91 (97.8%) stones were removed in one (87) or two (4) endoscopic session. There were 2 major complications (one bleeding and one severe pancreatitis) due to ERCP or a sphincterotomy. Two patients developed symptoms from unsuspected common bile duct stones after LC and were removed endoscopically. No complications during LC were due to ERCP or ES. CONCLUSIONS: Selective preoperative ERCP is an effective way of clearing the CBD stones before laparoscopic cholecystectomy, with low rate of complications related to endoscopic and laparoscopic procedures, and short mean hospital stay (5.5 days), according to the concept of minimally invasive treatment.

Hereditary spherocytosis is the most common red blood cell membrane disorder and often is associated with hemolytic crisis and premature cholelithiasis. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Laparoscopic cholecystectomy and splenectomy have been performed safely worldwide. We report our experience with seven patients (one male and six female, average age 12 years) who underwent combined laparoscopic splenectomy and cholecystectomy for hereditary spherocytosis. The patient was placed in supine position and the procedure performed with a five-trocar technique. Cholecystectomy was performed first, then splenectomy was achieved and the spleen removed by morcellation into a retrieval bag (five cases) or via a 4- to 5-cm left subcostal incision (two cases). No patient required conversion to open technique or blood transfusion. The mean blood loss was 162 mL, mean operative time 207 minutes, mean spleen size 14.5 cm, and median postoperative hospital stay 4 days. No perioperative mortality or major complications occurred in our series. After a median follow-up of 18 months all patients showed sharp hematologic improvement. Despite the small number of cases, we consider the combined laparoscopic approach safe and effective for the treatment of hereditary spherocytosis.

Laparoscopic splenectomy has gained increasing acceptance in the surgical management of a variety of splenic disorders, in particular hematological diseases. In this series, we report our experience with 20 patients (male:female ratio of 4:16 with median age of 16 years, range 5-49 years) who underwent this procedure because of ITP in 9 cases, spherocytosis in 7 and Cooley disease, sickle cell anemia, dyserythropoietic and hemolytic anemia in one case each. The patient was placed in a supine position using a fourtrocars technique. We did not perform pre-operative splenic artery embolization in any case. Spleen lower pole and its posterolateral attachments were dissected first, using electrocautery and endoclips. Vascular hilar isolation was achieved with an EndoGIA stapler and the spleen was removed by morcelation within a retrieval bag (16 cases) or via a 4-5 cm left subcostal incision (4 cases). One patient required conversion to open technique (conversion rate 5 %), because of uncontrolled bleeding from splenic hilum. Mean operative time was 165 min (range 100-240 min), mean splenic size was 13.5 cm (range 11-20 cm), with weight ranging between 140 and 1060 g and estimated blood loss was 151 ml (75-280 ml). No patient required a blood transfusion. Median postoperative hospital stay was 4 days (range 3-8 days). Postoperative complications occurred in 2 patients (10%), with no mortality rate in this series. Regarding the low complication rate and the advantages of a small abdominal trauma in the postoperative period, such as less postoperative pain, faster hospital discharge and better cosmetic results, the laparoscopic approach for elective splenectomy in hematological disorders has a substantial benefit for the patient.

It has been suggested that both the menstrual cycle phase and postoperative changes in prolactin (PRL) secretion at the time of surgery may influence the prognosis of breast cancer. The present study was carried out to evaluate the relation between menstrual cycle period and surgery-induced PRL variations. We evaluated 32 premenopausal women with operable breast carcinoma; 17 were in perimenstrual phase (days 1-6 and 21-28) and 15 were in the mid-cycle (days 7-20) period at the time of surgery. To investigate serum levels of PRL, venous blood samples were collected before and 7 days after surgery. Postoperative hyperprolactinemia occurred in 17/32 patients and it was statistically more frequent in patients surgically treated during the perimenstrual phase than in the mid-cycle phase (12/17 vs 5/15; p less than 0.05), while no other parameter (including axillary node and estrogen receptor status) showed a significant influence on hyperprolactinemia rate. The results suggest that in premenopausal breast cancer patients surgery-induced hyperprolactinemia may be influenced by the menstrual cycle phase at the time of surgery.
