The impact of splenic weight on laparoscopic splenectomy for splenomegaly.

BACKGROUND: Enlarged spleens increase the technical difficulties associated with laparoscopic splenectomy (LS). The aim of this study was to analyze the impact of splenic weight on the results of LS. METHODS: We performed a prospective analysis of 20 LS for splenomegaly and 40 LS for normal spleen in terms of intraoperative and early postoperative outcome. RESULTS: Patients with splenomegaly had longer operative times and higher conversion and transfusion rates than those with normal spleens. Patients with spleens weighing < 2000 G experienced less blood loss, fewer conversions, and a shorter postoperative hospital stay than those with spleens > 2000 g. No differences-except for the longer operative time-were observed between normal-sized spleens and those weighing < 2000 G. CONCLUSIONS: LS for splenomegaly is feasible for experienced laparoscopic surgeons. For spleens weighing < 2000 G, the outcome was comparable to that of normal spleens, whereas LS for spleens >2000 g was associated with a higher conversion rate, greater blood loss, a longer hospital stay, and increased morbidity.

Intraoperative cholangiography in laparoscopic cholecystectomy during residency in general surgery.

BACKGROUND: The role of laparoscopic intraoperative cholangiography (IC) in the diagnosis of asymptomatic choledocholithiasis is still controversial. The aim of this study was to evaluate the diagnostic-therapeutic impact and the educational implications of this method for residents specializing in general surgery. METHODS: We reviewed the records of 835 patients who underwent laparoscopic cholecystectomy for cholecystolithiasis without choledocholithiasis. IC was routinely performed by both expert surgeons and residents in general surgery. RESULTS: The cholecystectomy was completed laparoscopically in 804 cases, but conversion to open surgery was required in 31 cases. IC was not completed in 140 cases (17.4%), and in 44 cases it revealed a suspected choledocholithiasis. The stones were treated via laparoscopy in 36 cases, laparotomy in six cases, and endoscopic retrograde cholangiopancreatography (ERCP) in two cases. Five patients were not diagnosed wit h choledocholithiasis. In one case, a lesion of the choledochus was discovered and treated laparoscopically. A total of 610 IC were done by expert surgeons and 225 by residents. The duration of the cholecystectomy with IC was significantly different between the two groups (76.9 +/- 12 vs 92.4 +/- 11), as was the feasibility index (88.6% vs 80.6%). CONCLUSIONS: Laparoscopic IC is a safe and accurate procedure for the diagnosis of unrecognized choledocholithiasis. Teaching of this procedure as part of the specialization in general surgery would be opportune because it would provide surgical residents with an additional tool for the diagnosis and treatment of this pathology of the common bile duct.

Primary lymphoma of the liver: a case report and review of the literature.

Primary lymphoma of the liver (PLL) is a rare disease and estimation of the real number of cases may be difficult because strict diagnostic criteria for the definition of a primary lesion are quite often not followed. We report here on a case of a patient affected by PLL who underwent successful surgical resection of the lesion followed by chemotherapy and autologous bone marrow transplantation. The patient is alive and disease free 62 months after resection.

[Trans-umbilical cholecystectomy: a new laparoscopic cholecystectomy technique. Description of the technique and preliminary results]. / Colecistectomia trans-ombelicale: nuova tecnica di videolaparo-colecistectomia. Illustrazione della tecnica e risultati preliminari.

The aim of videolaparo-cholecystectomy is to achieve a good results with minimal surgical trauma. Recently there has been an evolution of this technique toward the progressive reduction of trauma with an improvement of the results, also from the aesthetical point of view. In this article we describe our new videolaparo-cholecystectomy technique. Trans-umbilical videolaparo-cholecystectomy represents a variant of the traditional technique. This new method allows the operation to perform with only two trocars positioned in the peritoneum cavity through only one umbilical incision. The technical innovation of this method consists of the substitution of the others trocars, utilized in the traditional technique, with an equal number of trans-parietal suspension wires. Up to now, we have given 95 patients this kind of operation being successful in 67% of the cases. We think that this new technique, requiring as it does only standard laparoscopic instruments, is in accordance with the philosophy of mini-invasive surgery. The suspension wires are responsible for minimal bile spreading which is not an important complication if the surgeon performs an accurate and through cleaning of the abdominal cavity at the end of the surgical procedure. The patient better accepts this technique because of its better aesthetical results. In spite of this there should be more evaluable data about trans-umbilical videolaparo-cholecystectomy especially about the incidence of post-operatory complications.

Elective transumbilical compared with standard laparoscopic cholecystectomy.

OBJECTIVE: To compare the transumbilical technique of laparoscopic cholecystectomy with standard laparoscopic cholecystectomy. DESIGN: Randomised open study. SETTING: Teaching hospital, Italy. SUBJECTS: 90 patients who required elective cholecystectomy under general anaesthesia. INTERVENTIONS: Standard laparoscopic cholecystectomy through 4 ports or transumbilical cholecystectomy through 2 ports. MAIN OUTCOME MEASURES: Amount of pain and analgesia, cost, side effects, and cosmesis. RESULTS: 25 patients were excluded from analysis (8 in the standard group because relevant data were not recorded; and 17 in the transumbilical group in 4 of whom relevant data were not recorded, and 13 for technical reasons). 32 patients who had standard, and 25 who had transumbilical cholecystectomy had operative cholangiograms. There were no complications, no side effects, and no conversions to open cholecystectomy. Those who had transumbilical cholecystectomy had significantly lower pain scores (p<0.05) and required significantly less analgesia during the first 24 hours (p<0.05) than those who had standard laparoscopic cholecystectomy. CONCLUSION: Once the learning curve has been completed, transumbilical cholecystectomy is possible without some of difficulties associated with standard laparoscopic cholecystectomy.
