RESUMO
BACKGROUND: The role of laparoscopy in the treatment of intrahepatic cholangiocarcinoma (ICC) remains unclear. This multicenter study examined the outcomes of laparoscopic liver resection for ICC. METHODS: Patients with ICC who had undergone laparoscopic or open liver resection between 2012 and 2019 at four European expert centers were included in the study. Laparoscopic and open approaches were compared in terms of surgical and oncological outcomes. Propensity score matching was used for minimizing treatment selection bias and adjusting for confounders (age, ASA grade, tumor size, location, number of tumors and underlying liver disease). RESULTS: Of 136 patients, 50 (36.7%) underwent laparoscopic resection, whereas 86 (63.3%) had open surgery. Median tumor size was larger (73.6 vs 55.1 mm, p = 0.01) and the incidence of bi-lobar tumors was higher (36.6 vs 6%, p < 0.01) in patients undergoing open surgery. After propensity score matching baseline characteristics were comparable although open surgery was associated with a larger fraction of major liver resections (74 vs 38%, p < 0.01), lymphadenectomy (60 vs 20%, p < 0.01) and longer operative time (294 vs 209 min, p < 0.01). Tumor characteristics were similar. Laparoscopic resection resulted in less complications (30 vs 52%, p = 0.025), fewer reoperations (4 vs 16%, p = 0.046) and shorter hospital stay (5 vs 8 days, p < 0.01). No differences were found in terms of recurrence, recurrence-free and overall survival. CONCLUSION: Laparoscopic resection seems to be associated with improved short-term and with similar long-term outcomes compared with open surgery in patients with ICC. However, possible selection criteria for laparoscopic surgery are yet to be defined.

BACKGROUND: The role of laparoscopic resection in patients with pancreatic cancer remains to be clarified, because previous reports have not clearly defined oncologic outcomes. The objective of the present study was to investigate this question with the rate of R0 resection and long-term survival as endpoints. METHODS: This retrospective observational study included prospectively collected data from 40 patients operated laparoscopically with curative intent for exocrine pancreatic malignancies identified among 250 consecutive patients undergoing laparoscopic pancreatic operations since 1997. All 40 patients had histologically verified exocrine pancreatic carcinoma. RESULTS: Ten patients (25%) with typical ductal adenocarcinoma of the pancreas were deemed nonresectable by laparoscopic staging. Laparoscopic distal pancreatectomy was performed in 29 patients; 8 resections were combined with resections of adjacent organs and 1 removal of a malignant intraductal papillary mucinous neoplasm what appeared to be ectopic pancreatic tissue. In 1 patient, the resection was completed by hand-assisted technique, and 1 procedure was converted to open resection. Postoperative morbidity was 23% (n = 7). The median hospital stay was 5 days (range, 1-30). The rate of R0 resections was 93%. Postoperative 3-year survivals rates were 36% for the entire cohort (n = 30) and 30% in typical ductal adenocarcinoma (n = 21). CONCLUSION: Laparoscopic distal pancreatectomy for exocrine pancreatic carcinoma is comparable with outcomes after open surgery and supports the concept that laparoscopic distal pancreatectomy is a safe, oncologic procedure.

OBJECTIVE: To analyze the immediate and long-term outcome after laparoscopic resection of colorectal liver metastases and difference between observed and predicted [Fong's and Basingstoke Predictive Index (BPI) scores] survivals. BACKGROUND: : Laparoscopic liver resection has been reported safe and feasible and improves postoperative course. The oncologic outcomes after resection of colorectal metastases are poorly reported. METHODS: Between August 1998 and January 2010, 122 patients underwent laparoscopic resection for colorectal liver metastases during 135 procedures at Rikshospitalet. Patients undergoing surgery between August 1998 and June 2009 were included in research analysis. The patients had median Fong's and BPI's scores of 2 (0-5) and 7 (0-23), respectively. Mainstream analysis of hospital data was done on intent-to-treat basis. Intraoperative incidents and postoperative complications were analyzed according to the Satava and Clavien-Dindo classifications. Median follow-up was 24 (0-100) months. RESULTS: One hundred fifty-one liver resections were performed in 107 patients during 118 procedures: 117 nonanatomic and 34 anatomic liver resections. There were 5 conversions to laparotomy (4.2%). The resection margin was free of tumor tissue in 141 (93.4%) of 151 specimens, and the distance between the resection margin and tumor tissue was median 6 (0-40) mm. Intraoperative incidents occurred in 14 cases (11.9%), including 5 (4.2%), 8 (6.8%), and 1 (0.8%) cases of grades I, II, and III, respectively. Postoperative complications were observed in 16 cases (14.3%), including 2, 3, 7, 3, 0, and 1 cases of grades I, II, IIIa, IIIb, IV, and V, respectively. During follow-up, 21 patients received repeat liver resection of recurrences (11 by laparoscopy and 10 by laparotomy). The 5-year overall survival rates were 51% as laparoscopically completed cases and 47% as intent-to-treat. The observed actuarial survival values exceeded the values expected by Fong's and BPI's score, with 10.2% and 6.7% as laparoscopically completed cases and with 3.8% and 2.4% as intent-to-treat, respectively. CONCLUSIONS: Laparoscopic resection is a favorable alternative to open liver resection for patients with colorectal liver metastases. The observed actuarial survival values after laparoscopic resection surpass the values expected by major scoring systems.

BACKGROUND: The introduction of laparoscopic liver resection has been challenging because new and safe surgical techniques have had to be developed, and skepticism remains about the use of laparoscopy for malignant neoplasms. We present herein a large-volume single-center experience with laparoscopic liver resection. DESIGN: Retrospective study. SETTING: Rikshospitalet University Hospital. PATIENTS: One hundred thirty-nine patients who underwent 177 laparoscopic liver resections in 149 procedures from August 18, 1998, through October 14, 2008. One hundred thirteen patients had malignant lesions, of whom 96 had colorectal metastases. INTERVENTION: Laparoscopic liver resection for malignant and benign lesions. MAIN OUTCOME MEASURES: Perioperative and oncologic outcomes and survival. RESULTS: Five procedures (3.4%) were converted to laparotomy and 1 (0.7%) to laparoscopic radiofrequency ablation. The remaining 143 procedures were completed laparoscopically, during which 177 liver resections were undertaken, including 131 nonanatomic and 46 anatomic resections. The median operative time and blood loss were 164 (50-488) minutes and 350 (<50-4000) mL, respectively. There were 10 intraoperative (6.7%) and 18 postoperative (12.6%) complications. One patient (0.7%) died. The median postoperative stay and opioid requirement were 3 (1-42) and 1 (0-11) days, respectively. Tumor-free resection margins determined by histopathologic evaluation were achieved in 140 of 149 malignant specimens (94.0%). The 5-year actuarial survival for patients undergoing procedures for colorectal metastases was 46%. CONCLUSIONS: In experienced hands, laparoscopic liver resection is a favorable alternative to open resection. Perioperative morbidity and mortality and long-term survival after laparoscopic resection of colorectal metastases appear to be comparable to those after open resections.

BACKGROUND: The last 15 years have been characterized by a rapid expansion of minimally invasive surgery as treatment for adrenal diseases. During these years, both indications and surgical techniques have shown improvements. This study analyzed an 11-year single-center experience with laparoscopic adrenalectomy. MATERIALS AND METHODS: Between January 1997 and April 2008, 242 laparoscopic adrenalectomies were performed in 220 patients at Rikshospitalet University Hospital. Of these, 192 patients were operated on for benign lesions, 23 for malignant lesions, and in 5 cases "en bloc" adrenalectomies were performed. Benign lesions included 136 hormonally active lesions (41 pheochromocytomas, 48 Conn adenomas, 25 Cushing adenomas, and 18 patients with Cushing's disease) and 56 with hormonally inactive lesions (among them, 47 nonfunctional adenomas). Malignant lesions included 16 adrenal metastases and 7 adrenocortical carcinomas. RESULTS: All adrenalectomies were completed laparoscopically. The median time of unilatateral adrenalectomy was 85 (range, 35-325) minutes. The median blood loss was 0 (range, 0-1100) mL. There were 6 intraoperative and 7 postoperative minor complications. The number of complications did not differ between the types of adrenal pathology. Only 19% of the patients required opioids postoperatively. Per- and postoperative parameters were homogeneous among patients with different adrenal lesions. The patients with adrenocortical carcinoma had a distinctive intraoperative course with an evidently longer operative time and higher blood loss. The median postoperative hospital stay was 2 (range, 1-15) days. Hospital stay was the only postoperative parameter where a difference was found between patients with different adrenal lesions. The patients with carcinoma, pheochromocytoma, and Cushing's disease had the longest median postoperative stay, respectively, 5 (range, 2-6), 3 (range, 1-15), and 3 (range, 2-6) days. CONCLUSIONS: Laparoscopic adrenalectomy is a safe, effective procedure providing improved fast and uncomplicated patient recovery independent of the type of adrenal lesion. Laparoscopic adrenalectomy can be easily introduced and may soon replace traditional open surgery in specialized centers.
