Single-Incision Laparoscopic Liver Resection for Colorectal Metastasis through Stoma Site at Time of Reversal of Diversion Ileostomy: A Case Report

Minimally invasive surgical techniques for liver tumors are gaining increased acceptance as an alternative to traditional resections by laparotomy. In this article we describe a laparoscopic liver resection of a metastatic lesion in a patient primarily operated for colorectal cancer. The resection was conducted as a single port procedure through the stoma aperture at time of reversal of the diversion ileostomy. Sigle incision liver resections may be less traumatic than conventional laparoscopy and could be applied in selected patients with both benign and malignant liver tumors

Laparoscopic versus open liver resection for intrahepatic cholangiocarcinoma: a multicenter propensity score-matched study

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, p¼ 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%, p¼ 0.025), fewer reoperations (4 vs 16%, p¼ 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

Outcome of laparoscopic surgery in patients with cystic lesions in the distal pancreas

Context Recent guidelines for the management of cystic lesions of the pancreas recommend observation for selected neoplasms using imaging criteria. However, current imaging modalities lack diagnostic accuracy, and the indication for surgery is debated. Objective In this study we have explored the outcome of laparoscopic distal pancreatic resections in all patients referred with potential pancreatic cystic neoplasms, with histological diagnosis as endpoint. Methods Between 1997 and 2009 all patients referred to our tertiary referral centre having a cystic neoplasm of the distal pancreas accepted for surgery were included in the present observational study. Results A total of 69 patients were included. Sixty-two patients underwent distal pancreatectomies, in whom 19 were spleen-preserving, and 7 enucleations were performed. Two procedures were converted to open technique. The lesions removed in 27 patients (39%) were either malignant or premalignant. The final diagnoses were serous cystic neoplasm (n=29), mucinous cystic neoplasm (n=12), pseudocyst (n=11), solid pseudopapillary neoplasm (n=10), intraductal papillary mucinous neoplasm (n=5) and other (n=2). Overall morbidity was 33%; 56% of the complications were classified as mild. Fistula rate was 10%. One patient died postoperatively from a cerebral haemorrhage. Conclusion Most complications after laparoscopic distal resection of cystic pancreatic lesions are mild, but the proportion of patients with benign lesions (61%) has to be reduced by focused preoperative investigations. Endoscopic ultrasound examination (EUS), enabling aspiration of cyst fluid and fine needle aspiration is an additional option for the preoperative workup

Evolution of laparoscopic liver surgery: 20-year experience of a Norwegian high-volume referral center

Abstract Background Laparoscopic liver surgery has evolved to become a standard surgical approach in many specialized centers worldwide. In this study we present the evolution of laparoscopic liver surgery at a single high-volume referral center since its introduction in 1998. Methods Patients who underwent laparoscopic liver resection (LLR) between August 1998 and December 2018 at the Oslo University Hospital were analyzed. Perioperative outcomes were compared between three time periods: early (1998 to 2004), middle (2005 to 2012) and recent (2013–2018) . Results Up to December 2020, 1533 LLRs have been performed. A total of 1232 procedures were examined (early period, n  = 62; middle period, n  = 367 and recent period, n  = 803). Colorectal liver metastasis was the main indication for surgery (68%). The rates of conversion to laparotomy and hand-assisted laparoscopy were 3.2% and 1.4%. The median operative time and blood loss were 130 min [interquartile range (IQR), 85–190] and 220 ml (IQR, 50–600), respectively. The total postoperative complications rate was 20.3% and the 30-day mortality was 0.3%. The median postoperative stay was two (IQR, 2–4) days. When comparing perioperative outcomes between the three time periods, shorter operation time (median, from 182 to 120 min, p  &lt; 0.001), less blood loss (median, from 550 to 200 ml, p  = 0.023), decreased rate of conversions to laparotomy (from 8 to 3%) and shorter postoperative hospital stay (median, from 3 to 2 days, p  &lt; 0.001) was observed in the later periods, while the number of more complex liver resections had increased. Conclusion During the last two decades, the indications, the number of patients and the complexity of laparoscopic liver procedures have expanded significantly. Initially being an experimental approach, laparoscopic liver surgery is now safely implemented across our unit and has become the method of choice for surgical treatment of most liver tumors

Laparoscopic parenchyma-sparing liver resection for large (≥ 50 mm) colorectal metastases.

Abstract Background Traditionally, patients with large liver tumors (≥ 50 mm) have been considered for anatomic major hepatectomy. Laparoscopic resection of large liver lesions is technically challenging and often performed by surgeons with extensive experience. The current study aimed to evaluate the surgical and oncologic safety of laparoscopic parenchyma-sparing liver resection in patients with large colorectal metastases. Methods Patients who primarily underwent laparoscopic parenchyma-sparing liver resection (less than 3 consecutive liver segments) for colorectal liver metastases between 1999 and 2019 at Oslo University Hospital were analyzed. In some recent cases, a computer-assisted surgical planning system was used to better visualize and understand the patients’ liver anatomy, as well as a tool to further improve the resection strategy. The surgical and oncologic outcomes of patients with large (≥ 50 mm) and small (&lt; 50 mm) tumors were compared. Multivariable Cox-regression analysis was performed to identify risk factors for survival. Results In total 587 patients met the inclusion criteria (large tumor group, n  = 59; and small tumor group, n  = 528). Median tumor size was 60 mm (range, 50–110) in the large tumor group and 21 mm (3–48) in the small tumor group ( p  &lt; 0.001). Patient age and CEA level were higher in the large tumor group (8.4 μg/L vs. 4.6 μg/L, p  &lt; 0.001). Operation time and conversion rate were similar, while median blood loss was higher in the large tumor group (500 ml vs. 200 ml, p  &lt; 0.001). Patients in the large tumor group had shorter 5 year overall survival (34% vs 49%, p  = 0.027). However, in the multivariable Cox-regression analysis tumor size did not impact survival, unlike parameters such as age, ASA score, CEA level, extrahepatic disease at liver surgery, and positive lymph nodes in the primary tumor. Conclusion Laparoscopic parenchyma-sparing resections for large colorectal liver metastases provide satisfactory short and long-term outcomes. Graphical abstrac
