Background:Laparoscopic hepatectomy has presented great importance for treating malignant hepatic lesions. Aim:To evaluate its impact in relation to overall survival or disease free of the patients operated due different hepatic malignant tumors. Methods:Thirty-four laparoscopic hepatectomies were performed in 31 patients with malignant neoplasm. Patients were distributed as: Group 1 - colorectal metastases (n=14); Group 2 - hepatocellular carcinoma (n=8); and Group 3 - non-colorectal metastases and intrahepatic cholangiocarcinoma (n=9). The conversion rate, morbidity, mortality and tumor recurrence were also evaluated. Results:Conversion to open surgery was 6%; morbidity 22%; postoperative mortality 3%. There was tumor recurrence in 11 cases. Medians of overall survival and disease free survival were respectively 60 and 46 m; however, there was no difference among studied groups (p>0,05). Conclusion:Long-term outcomes of laparoscopic hepatectomy for treating hepatic malignant tumors are satisfactory. There is no statistical difference in relation of both overall and disease free survival among different groups of hepatic neoplasms.
Laparoscopic hepatectomy is a safe surgical approach for treating both benign and malignant hepatic lesions. This small series showed no mortality, low morbidity and good cosmetic results.
Background:Laparoscopic distal pancreatectomy has been the choice for resection of
distal pancreas lesions due many advantages over open approach. Spleen
preservation technique seems minimizes infectious complications in long-term
outcome. Aim:To present the results of laparoscopic distal pancreatectomies with spleen
preservation by Kimura´s technique (preservation of spleen blood vessels)
performed by single surgical team. Methods:Retrospective case series aiming to evaluate both short and long-term
outcomes of laparoscopic distal pancreatectomies with spleen preservation.
Results: A total of 54 laparoscopic distal pancreatectomies were performed, in which
26 were laparoscopic distal pancreatectomies with spleen preservation by
Kimura´s technique. Mean age was 47.9 years-old (21-75) where 61.5% were
female. Mean BMI was 28.5 kg/m² (18-38.8). Mean diameter of lesion was 4.3
cm (1.8-7.5). Mean operative time was 144.1 min (90-200). Intraoperative
bleeding was 119.2 ml (50-600). Conversion to laparotomy 3% (n=1).
Postoperative morbidity was 11.5%. Postoperative mortality was null. Mean of
hospital stay was 4.8 days (2-14). Mean time of follow-up period was 19.7
months (2-60). There was no neoplasm recurrence or mortality on evaluated
period. There was no infectious complication. Conclusion:Laparoscopic distal pancreatectomy with spleen and splenic vessels
preservation is feasible, safe, and effective procedure. This technique
presented both low morbidity and null mortality on this sample. There were
neither infectious complications nor neoplasm recurrence on long-term
follow-up period.
Background: Laparoscopic distal pancreatectomy (LDP) is the preferred approach for
resection of tumors in the distal pancreas because of its many advantages
over the open approach. Aim: To analyse and compare short and long-term outcomes from LDP performed
through two different techniques: with splenectomy vs. spleen preservation
and splenic vessel preservation. Method: Fifty-eight patients were operated and subsequently divided between two
groups: Group 1, LDP with splenectomy (LDPS); and Group 2, LDP with spleen
preservation and preservation of splenic vessels (LDPSPPSV). Results:The epidemiological characteristics were statistically similar between the
two groups (age, gender, BMI and lesion size). Both the mean of operative
time (p=0.04) and the mean of intra-operative blood loss (p=0,03) were
higher in Group 1. The mean of resected lymph nodes was also higher in Group
1 (p<0.000). There were no statistic differences between the groups in
relation to open conversion, morbidity or early postoperative mortality. The
mean hospital stay was similar between groups. Pancreatic fistula (grade B
and C) was similar between the groups. The mean of overall follow-up was
37.6 months (5-96). Late complications were similar between the groups. Conclusion: Both techniques were superimposable; however, LDPS presented, respectively,
higher intra-operative bleeding, longer duration of the operation and higher
number of lymph nodes resected. No differences were observed in the studied
period in relation to the appearance of infections or neoplasm related to
splenectomy during follow-up. Maintenance of the spleen avoided periodic
immunizations in patients in LDPSPSV. It is indicated in small pancreatic
lesions with indolent course.
