Surgical approach to the intraabdominal infections.

AIM: The term intraabdominal infectioncomprises a broad of variety of pathological conditions which are characterized by signs of systemic infection as a response to an abdominal source of infection and ranges from a confined problem to a devastating disease regarding all organ systems. Septic abdomen is an interesting challenge in general surgery: to decide when and how to treat septic abdomen lacks of a general consensus and has not been standardized yet. METHODS: A total of 1 110 patients underwent surgical treatment for abdominal infection in a period of 10 years in the Department of Surgery of San Gerardo Hospital, Monza, Italy. We focused our attention on 94 patients who required re-exploration for residual or recurrent intra-abdominal infection. RESULTS: The procedure was associated with a mortality rate of 40%. The median number of re-explorations was 5.1. CONCLUSION: Planned multiple relaparotomies with temporarily abdomen closure are performed only in a selected high mortality risk group of elderly patients with surgical evidence of diffuse peritonitis, presence of primary infectious process of more than 72 hours, and a APACHE II score > 20. Relaparotomy on demand is required instead in those patients who develop a clinical deterioration after a first safe surgical control of the source of infection. Lack of improvement is not considered a condition to reoperate. Early detection of persisting infection, < 24-36 hours, is an important prognostic factor of outcome.

Laparoscopic splenectomy using Ligasure. Preliminary experience.

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.

Mesenteric cyst neoformation. A case report.

Mesenteric cysts are rare lesions, with 1 case per 100,000 hospital admission reported. They have to be differentiated from ovarian cysts, gastrointestinal duplications and desmoid cysts. The symptoms are variable, ranging from asymptomatic cases with incidental discovery to chronic abdominal discomfort and acute abdomen. They are usually correlated to the location and the size of the lesion. Abdominal ultrasonography and computed tomography may lead to a correct diagnosis, which is regularly made at the time of abdominal exploration. Surgery is the treatment of choice, consisting with the removal of the cyst, eventually associated with bowel resection. It has to be radical in order to prevent the recurrence of the disease. A case of mesenteric cyst in a sixty-nine-years-old woman hospitalized for chronic abdominal pain is reported. In this case the cyst has been enucleated from the mesentery with open surgery without the need for bowel resection.

Laparoscopic cholecystectomy and unsuspected gallbladder cancer.

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.

[The use of the biofragmentable ring (BAR-Valtrac) in colon surgery].

BACKGROUND: Clinical results of colic anastomosis using biofragmentable anastomosis ring (BAR-Valtrac) are presented. Such a method showed to be a real alternative technique to the usual ones. METHODS: Eighty-six colic anastomosis using BAR are collected, 76 of which performed as elective surgery and 10 in emergency. The patients were 47 males and 39 females, with a mean age of 64 years. In 63 cases the patients were affected by colic neoplastic disease, in 16 by complicated diverticular disease (stenosis or perforation) and 7 patients had neoplastic disease of other organs involving the colon BAR device was used in 48 colic reconstructions after segmentary resection and in 38 colic reconstructions after left hemicolectomy. In each case 31-34 mm BAR were used. RESULTS: No perioperative death occurred in our series. Only one case (2%) of anastomotic leak was observed, while in 3 cases (4%) intestinal canalization disorders occurred. No problems for ring expulsion occurred in any patient. Three late complications were observed, as three cases of asymptomatic substenosis discovered during instrumental follow-up and spontaneously cleared up. CONCLUSIONS: On the basis of clinical results, and according to those reported in literature BAR anastomosis is considered a safe, feasible and easy technique to perform colic anastomosis, even in emergency, limited to the intraperitoneal tract of the colon.

[Videolaparoscopic cholecystectomy. Experience and results in 1019 cases].

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.

Laparoscopic versus open splenectomy: a comparative study.

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.

[Hernia repair with prolene mesh according to the Lichtenstein technique. Results of 692 cases].

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.

[Sequential endo-laparoscopic treatment in patients with common bile calculi].

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.

[Gallbladder carcinoma and laparoscopic cholecystectomy. An emergent problem].

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.

Combined laparoscopic splenectomy and cholecystectomy for the treatment of hereditary spherocytosis: is it safe and effective?

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.

Vitamin E as adjuvant in emulsified vaccine for chicks.

Mineral oil was partially replaced with D, L-alpha-tocopheryl acetate (vitamin E) in bacterial and viral inactivated emulsified vaccines. Vitamin E increased the immune response to the viral antigen (Newcastle disease virus) used but not to the bacterial antigen (Escherichia coli) when its presence in the oil phase did not exceed 30%. Inoculated vitamin E may have enhanced the immune response by interacting with the immune-competent cells involved in the inflammatory reaction that followed inoculation of emulsified vaccines.

Effects of somatostatin on acute pancreatitis induced in rats by injection of taurocholate and trypsin into a temporarily closed duodenal loop.

The effect of somatostatin on the course and severity of experimental pancreatitis was tested. Acute pancreatitis was induced in 210 Sprague-Dawley rats by injecting a 4.3% sodium taurocholate solution, saturated with trypsin, into a temporarily closed duodenal loop. Immediately after the end of the surgical procedure somatostatin or, alternatively, normal saline were administered as a bolus followed by continuous subcutaneous infusion for 9 h. Ninety rats (30 untreated, 30 saline-treated and 30 somatostatin-treated) were sacrificed 10 h after the induction of pancreatitis to assess the histologic severity of pancreatic lesions, the amount of peritoneal exudate and the circulating levels of amylase. In another 120 rats (40 untreated, 40 saline-treated and 40 drug-treated) the mortality rate was evaluated so that the histologic examination of the pancreas followed spontaneous death. In sacrificed animals somatostatin treatment lowered serum amylase levels and definitely improved pancreatic histopathology (edema, leucocyte infiltration and necrosis). The drug prevented the occurrence of severe necrosis in all treated animals. Somatostatin did not affect the mortality rate of pancreatitic rats (70%) although post-mortem histologic examination revealed significantly less pancreatic histopathology in drug-treated rats than in their controls.

A case of carcinoid of Meckel's diverticulum associated with gastric adenocarcinoma.

Meckel's diverticulum is an uncommon gastrointestinal congenital anomaly that occurs in 1-3% of the population. It is sometimes associated with complications related to the presence of ectopic tissue (obstruction, ulceration, hemmorhage, inflammation, perforation, fistula and tumors). Neoplastic degeneration of Meckel's diverticulum mucosa is rare, developing in only 1-5% of all diverticula, usually asymptomatic and occasionally discovered. Disease is metastatic, usually to the liver, in 25% of cases. We report a case of asymptomatic unsuspected carcinoid of Meckel's diverticulum with ileal, hepatic and mesenteric metastasis discovered during a gastrectomy performed for gastric adenocarcinoma. The patient underwent ileal and Meckel diverticulum resection, excision of mesenterial metastasis and liver bisegmentectomy. Furthermore, total gastrectomy with esophago-jejunal anastomosis was performed. After an 18-month follow-up period, the patient is alive and disease free. Owing to possible neoplastic degeneration, Meckel's diverticulum should be resected when occasionally discovered. In the presence of a carcinoid tumor, even if associated with metastatic disease, extended resection is recommended.

Laparoscopic splenectomy for hematological disorders. Our experience in adult and pediatric patients.

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.
