Benchmarking postoperative outcomes after open liver surgery for cirrhotic patients with hepatocellular carcinoma in a national cohort.

BACKGROUND: Benchmark analysis for open liver surgery for cirrhotic patients with hepatocellular carcinoma (HCC) is still undefined. METHODS: Patients were identified from the Italian national registry HE.RC.O.LE.S. The Achievable Benchmark of Care (ABC) method was employed to identify the benchmarks. The outcomes assessed were the rate of complications, major comorbidities, post-operative ascites (POA), post-hepatectomy liver failure (PHLF), 90-day mortality. Benchmarking was stratified for surgical complexity (CP1, CP2 and CP3). RESULTS: A total of 978 of 2698 patients fulfilled the inclusion criteria. 431 (44.1%) patients were treated with CP1 procedures, 239 (24.4%) with CP2 and 308 (31.5%) with CP3 procedures. Patients submitted to CP1 had a worse underlying liver function, while the tumor burden was more severe in CP3 cases. The ABC for complications (13.1%, 19.2% and 28.1% for CP1, CP2 and CP3 respectively), major complications (7.6%, 11.1%, 12.5%) and 90-day mortality (0%, 3.3%, 3.6%) increased with the surgical difficulty, but not POA (4.4%, 3.3% and 2.6% respectively) and PHLF (0% for all groups). CONCLUSION: We propose benchmarks for open liver resections in HCC cirrhotic patients, stratified for surgical complexity. The difference between the benchmark values and the results obtained during everyday practice reflects the room for potential growth, with the aim to encourage constant improvement among liver surgeons.

Biliary Tree Cysts and Surgical Treatment: Outcomes in a Multicentric Study.

Background: Biliary tree cysts (BTCs) represent an either localized or multifocal abnormal dilatation of the biliary tree, which entails an increased risk of acute cholangitis and cholangiocarcinoma (2.5%-16%). Its incidence in Western countries is ∼1/100.000-1/150.000, being more frequent in Asia (1/1.000). These cysts are usually classified according to Todani classification, which is based on site and morphology of cysts. Patients and Methods: This is a retrospective multicentric descriptive study of patients surgically treated for BTCs. From 2005 to 2018, 25 cases were collected between Hospital de la Santa Creu i Sant Pau (Barcelona, Spain) and Ospedale San Paolo (Savona, Italy). Clinical presentation was characterized by abdominal pain, jaundice, fever, and sometimes weight loss. Eight patients presented Todani type I, 1 patient Todani type II, 3 patients Todani III, 1 patient Todani type IV, and 12 patients Todani type V. Results: Among the 25 surgically treated patients, 12 patients underwent liver resection, 7 patients underwent resection of the extrahepatic biliary tree, 3 patients underwent BTC removal through a duodenotomy, 1 patient underwent resection of the extrahepatic biliary tree and liver resection, and 2 patients underwent pancreatoduodenectomy. Overall 30-day morbidity rate was 20%, and 90-day mortality was 0%. Pathologic examination confirmed diagnosis of cholangiocarcinoma in 5 patients (20%). After a median follow-up of 59 months, 20 patients are alive and in good conditions, whereas 50% of patients with cholangiocarcinoma died for disease progression. Conclusions: Surgical treatment for BTCs is associated with acceptable postoperative outcomes, with moderate morbidity and null mortality rates. Moreover, the risk of developing cholangiocarcinoma is still high that prompts surgical treatment once diagnosis is made.

Surgical treatment of liver and kidney metastasis from an adenoid cystic carcinoma of the submandibular gland: case report.

INTRODUCTION: Adenoid cystic carcinomas (ACCs) account for 10% of all malignant salivary tumours. They are slow-growing but locally aggressive. Reports of liver and renal metastases are rare. CASE DESCRIPTION: A 58-year-old woman who had undergone resection of a left submandibular ACC in 1995 was referred to our centre for follow-up in 2018. A computed tomography scan revealed two lesions: one on segment six of the liver and the other on a kidney. A hepatic wedge resection and right nephrectomy were performed. The postoperative course was uneventful. At 2-year follow-up, the patient was alive and well with no evidence of disease. CONCLUSION: Management of ACC is a therapeutic challenge because of its tendency for distant metastases. The literature recommends regular follow-up imaging and radical surgical treatment but specific guidelines for the approach to recurrence are lacking.

Performance of Comprehensive Complication Index and Clavien-Dindo Complication Scoring System in Liver Surgery for Hepatocellular Carcinoma.

BACKGROUND: We aimed to assess the ability of comprehensive complication index (CCI) and Clavien-Dindo complication (CDC) scale to predict excessive length of hospital stay (e-LOS) in patients undergoing liver resection for hepatocellular carcinoma. METHODS: Patients were identified from an Italian multi-institutional database and randomly selected to be included in either a derivation or validation set. Multivariate logistic regression models and ROC curve analysis including either CCI or CDC as predictors of e-LOS were fitted to compare predictive performance. E-LOS was defined as a LOS longer than the 75th percentile among patients with at least one complication. RESULTS: A total of 2669 patients were analyzed (1345 for derivation and 1324 for validation). The odds ratio (OR) was 5.590 (95%CI 4.201; 7.438) for CCI and 5.507 (4.152; 7.304) for CDC. The AUC was 0.964 for CCI and 0.893 for CDC in the derivation set and 0.962 vs. 0.890 in the validation set, respectively. In patients with at least two complications, the OR was 2.793 (1.896; 4.115) for CCI and 2.439 (1.666; 3.570) for CDC with an AUC of 0.850 and 0.673, respectively in the derivation cohort. The AUC was 0.806 for CCI and 0.658 for CDC in the validation set. CONCLUSIONS: When reporting postoperative morbidity in liver surgery, CCI is a preferable scale.

Two-stage hepatectomy in two regional district community hospitals: perioperative safety and long-term survival.

INTRODUCTION: Surgical resection offers the best chance of cure for patients with colorectal liver metastases (CRLMs). Two-stage hepatectomy (TSH) has been demonstrated to be safe and effective to obtain curative resection in patients with multiple, bilobar CRLMs that are unresectable in a single procedure. Up to now TSH has been the prerogative of dedicated liver surgery centers. The aim of this study was to assess the safety and effectiveness of TSH also in community hospitals. METHODS: Of 294 patients operated on for CRLMs between September 1997 and June 2012 in 2 district community hospitals (belonging to the same regional healthcare district), 43 (14.6%) were scheduled for TSH. Thirty-eight/43 received neoadjuvant and/or bridge chemotherapy (2 neoadjuvant only, 4 neoadjuvant and bridge, 32 bridge only). RESULTS: The mean follow-up was 35.74 ± 29.53 months. Five-year overall survival (OS) was 31.4%, with a median survival time of 31 months. Twenty-nine patients completed the planned procedure (OS: 42.9%; median 47 months), while 14 did not because of disease progression (OS: 0%; median 13 months). No operative mortality occurred within the first 90 days either after the first or second stage. CONCLUSIONS: Our results suggest good efficacy and safety of TSH even when performed in a community hospital setting. Shifting patient selection from neoadjuvant to bridge chemotherapy had no impact on outcome once the clearing of the liver had been achieved. In patients presenting with synchronous CRLMs, simultaneous colorectal resection and clearing of the less involved hemiliver as the first surgical step is feasible without any negative impact on outcome.

Laparoscopic cholecystectomy can be performed safely with only three ports in the majority of cases.

Reducing the number of ports used to perform laparoscopic cholecystectomy (LC) is indicated as means of further minimising postoperative pain, allowing a rapid return to activity and work, and obtaining patient satisfaction and better cosmetic results. It is still debatable whether the three-port technique is comparably safe. Since 2001, 374 consecutive patients underwent laparoscopic cholecystectomy in elective and emergency surgery. Three ports were routinely positioned and the need for a fourth cannula was evaluated during the surgical procedure. Of the 374 consecutive cholecystectomies performed, 204 were completed with three ports and 161 needed a fourth port to be completed, while 9 required conversion to laparotomy. Patients who were operated on with just three ports were significantly younger and mostly female. Complications of procedures completed with three ports were negligible and those of procedures completed with four ports were in line with the recent literature. Our experience shows that the three-port technique is always a good initial option when performing laparoscopic cholecystectomy. It is safe and requires conversion to four-port placement in only a minority of cases overall.

Hydatid cyst of the liver: spontaneous rupture with peritoneal and thoracic involvement. Report of a case.

Hydatidosis due to Echinococcus granulosus is an endemic parasitic disease in Mediterranean countries. The most frequent anatomical locations are the liver and lung and the most significant complication of liver hydatidosis is rupture into the biliary tract. Spontaneous rupture into the free peritoneal cavity associated with thoracic involvement is an unusual complication accompanied by a high mortality rate. An isolated abdominal approach is necessary when peritoneal cavity drainage is required and may be sufficient in cases of contamination of the pleural cavity by scolices without suppurative involvement. An unusual case of spontaneous rupture of a hydatid cyst of the liver into the free peritoneal cavity associated with diaphragmatic and pleural involvement is reported. This complication requires immediate surgical treatment consisting in a combined thoracic and abdominal approach. The isolated abdominal approach not requiring thoracotomy may be satisfactory if there is no intrathoracic damage due to the chronic presence of scolices. Intrabdominal and intrathoracic cyst rupture still remains a serious complication because of the complexity of the lesions which are often difficult to treat in a one-stage operation. The mortality remains high in various series.

Laparoscopic treatment of Morgagni-Larrey hernia: technical details and report of a series.

Three patients with Morgagni-Larrey hernia were admitted to the surgical department between August 2000 and September 2003 with slight chest pain and dyspnea. Laparoscopic repair of the diaphragmatic hernia was performed using a tension-free closure of the defects with either Vicryl-Prolene or dual facing mesh fixed by Prolene extracorporeal knots and Endostitch devices. The patients were discharged on postoperative day 5 without complications. Mean follow-up has been 23 months (range, 15-36 months) and no recurrence or morbidity related to the procedure has been seen. Laparoscopic repair of Morgagni-Larrey hernia represents an attractive alternative to open surgery. The benefits are gentle and easy manipulation of the content of the sac, reduced surgical trauma, and rapid and uneventful recovery.

Conservative management of a spleen trauma using radiofrequency.

AIM OF THE STUDY: Conservative operative management of a splenic injury has become more and more employed in order to preserve the immune function of the organ. CASE REPORT: A case of a rupture of the spleen successfully treated with the use of a radiofrequency thermal energy generator is eported. The parenchymal tear was coagulated by a one cooled tip needle electrode. There were no postoperative complications and the function of the spleen was preserved. CONCLUSIONS: The technique cannot be applied in case of lesion of the major vessels or in case of avulsion of the hilum. This technique integrates to the others to make the operative conservative management of a splenic injury more and more feasible.

Radiofrequency-assisted liver resection.

Radiofrequency (RF)-assisted thermal ablation has been used with increasing frequency for unresectable hepatic tumors. This new approach employs RF energy to coagulate the liver at the hepatic resection line after which hepatic resection is performed with the use of a common scalpel. This procedure was used in three patients with hepatocellular carcinoma and in five patients with colorectal metastasis to the liver. These eight patients underwent a total of two left bisegmentectomies, three segmentectomies, and seven wedge resections. Mean operative time was 220 minutes. A mean of 78 sessions of RF-assisted ablation were required for these resections. Mean blood loss was 46 ml; no device other than RF ablation was required to obtain hemostasis. None of the patients needed a blood transfusion. Preoperative hemoglobin was 12.8 gm/dl and postoperative hemoglobin was 11.3 gm/dl. There were no perioperative deaths. Postoperative complications occurred in two patients: a liver abscess in one and heart failure in the other. The mean hospital stay was 9.4 days. This new approach, integrated with other techniques, reduces blood loss and coagulates the margins of resection during liver surgery. This new technique has two limitations: (1) it cannot be applied near main portal pedicles, and (2) it requires a long operative time. The best indication for this technique is when segmentectomy is required in patients with cirrhosis. Its role in major hepatic resections has yet to be determined. Further progress in the development of thermal ablation techniques and experience gained during the learning curve should help reduce the operative time, thereby improving the safety and efficacy of this procedure.
