Background
Malignant transformation of hepatocellular adenomas (HCAs) into hepatocellular carcinomas (HCCs) has been reported repeatedly and is considered to be one of the main reasons for surgical treatment. However, its actual risk is currently unknown.

Malignant transformation of hepatocellular adenomas into hepatocellular carcinomas: a systematic review including more than 1600 adenoma cases.

Importance Subtotal cholecystectomy (SC) is a procedure that removes portions of the gallbladder when structures of the Calot triangle cannot be safely identified in “difficult gallbladders.” Objective To conduct a systematic review and meta-analysis to evaluate current studies and present an evidence-based assessment of the outcomes for the techniques available for SC. Data Sources A literature search of the PubMed/MEDLINE (1954 to November 2013) and EMBASE (1974 to November 2013) databases was conducted. Search criteria included the words subtotal , partial , insufficient or incomplete , and cholecystectomy . Study Selection Inclusion criteria were all randomized, nonrandomized, and retrospective studies with data on SC techniques and outcomes. Exclusion criteria were studies that reported data on SC along with other interventions (eg, cholecystostomy) without the possibility to discriminate results specific to SC. Data Extraction and Synthesis This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Main Outcomes and Measures The primary outcome of the study was the occurrence of common bild duct injury. Secondary outcomes included the occurrence of other SC-related morbidities, such as hemorrhage, subhepatic collection, bile leak, retained stones, postoperative endoscopic retrograde cholangiopancreatography, wound infection, reoperation, and mortality. Results Thirty articles were included. Subtotal cholecystectomy was typically performed using the laparoscopic technique (72.9%), followed by the open (19.0%) and laparoscopic converted to open (8.0%) techniques. The most common indications were severe cholecystitis (72.1%), followed by cholelithiasis in liver cirrhosis and portal hypertension (18.2%) and empyema or perforated gallbladder (6.1%). Morbidity rates were relatively low (postoperative hemorrhage, 0.3%; subhepatic collections, 2.9%; bile duct injury, 0.08%; and retained stones, 3.1%); the rate for bile leaks was higher (18.0%). Reoperations were necessary in 1.8% of the cases; the 30-day mortality rate was 0.4%. The laparoscopic approach produced less risk of subhepatic collection (odds ratio [OR], 0.4; 95% CI, 0.2-0.9), retained stones (OR, 0.5; 95% CI, 0.3-0.9), wound infection (OR, 0.07; 95% CI, 0.04-0.2), reoperation (OR, 0.5; 95% CI, 0.3-0.9), and mortality (OR, 0.2; 95% CI, 0.05-0.9) but more bile leaks (OR, 5.3; 95% CI, 3.9-7.2) compared with the open approach. Conclusions and Relevance Subtotal cholecystectomy is an important tool for use in difficult gallbladders and achieves morbidity rates comparable to those reported for total cholecystectomy in simple cases. The various technical differences appear to influence outcomes only for the laparoscopic approach.

Subtotal Cholecystectomy for “Difficult Gallbladders”: Systematic Review and Meta-analysis

Incidence and prevention of ventral incisional hernia.

Hepatic resection had an impressive growth over time. It has been widely performed for the treatment of various liver diseases, such as malignant tumors, benign tumors, calculi in the intrahepatic ducts, hydatid disease, and abscesses. Management of hepatic resection is challenging. Despite technical advances and high experience of liver resection of specialized centers, it is still burdened by relatively high rates of postoperative morbidity and mortality. Especially, complex resections are being increasingly performed in high risk and older patient population. Operation on the liver is especially challenging because of its unique anatomic architecture and because of its vital functions. Common post-hepatectomy complications include venous catheter-related infection, pleural effusion, incisional infection, pulmonary atelectasis or infection, ascites, subphrenic infection, urinary tract infection, intraperitoneal hemorrhage, gastrointestinal tract bleeding, biliary tract hemorrhage, coagulation disorders, bile leakage, and liver failure. These problems are closely related to surgical manipulations, anesthesia, preoperative evaluation and preparation, and postoperative observation and management. The safety profile of hepatectomy probably can be improved if the surgeons and medical staff involved have comprehensive knowledge of the expected complications and expertise in their management. This review article focuses on the major postoperative issues after hepatic resection and presents the current management.

Management of post-hepatectomy complications

Background: Posthepatectomy liver failure (PHLF) is one of the most serious complications after liver resection and is still reported in up to 8% after liver resection. Aims: To provide an overview about the current status of risk analysis and definition of PHLF. Prevention and treatment is also discussed. Methods: A literature review was carried out on PubMed using the terms ‘liver failure’, ‘posthepatectomy’ and ‘liver surgery’ to search relevant papers. Discussion: PHLF remains a serious problem in patients undergoing major liver resection. Adequate preoperative risk assessment and an optimal postoperative treatment are essential for PHLF prevention.

Posthepatectomy liver failure.

An 89-year-old patient was hospitalized with signs of acute lithiasic cholecystitis and gastric emptying failure. The decision for surgery was taken and a subhepatic block was evidenced, caused by a perforated gangrenous cholecystitis with pericholecystic abscess, a cholecysto-antroduodenal fistula with two gallstones, 9/5 and 4/3 cm in size, impacted in the duodenum. It was necessary to perform an Y-en-Roux antroduodenojejunal anastomosis because an antroduodenal parietal defect resulted after the removal of the gangrenous gallbladder. The immediate and long term postoperative evolution in terms of anastomosis functionality was good.

We report the case of a laparoscopic resection of a symptomatic duodenal diverticulum. A 35 year old female with history of pain in the upper abdomen, nausea and regurgitation was diagnosed with a diverticulum of the second portion of the duodenum on the external border at upper gastrointestinal radiography. The diverticulum size was medium (2 cm in diameter). Under general anesthesia, a pneumoperitoneum was created. Four trocars were inserted into the peritoneal cavity for this intervention. After the sectioning of posterior parietal peritoneum on the external border of the second portion of duodenum, the diverticulum was dissected. The resection was performed with an endo-GIA linear stapler at the base of the diverticulum. One subhepatic drain was inserted. The operative time was 30 min. There were no intra- or postoperative complications. Postoperative gastrointestinal series revealed no signs of diverticulum or stenosis on the second portion of the duodenum. The patient was discharged in the fifth postoperative day after a normal course. The follow-up evaluation was normal.

Laparoscopic resection of duodenal diverticulum. A case report.

The porcelain gallbladder is uncommon type of chronically inflamed gallbladder wall considered to be associated with a high frequency of adenocarcinoma and subsequently not suitable for a laparoscopic approach. In 12,000 patients chosen for a laparoscopic cholecystectomy 4 porcelain gallbladders were diagnosed. In 2 cases the laparoscopic approach was successful. One conversion was due to an unconfirmed suspicion of gallbladder cancer and the other one to a fistula between the gallbladder and the common bile duct. Patients with a preoperative diagnosis of porcelain gallbladder must not be excluded from the laparoscopic approach yet a low threshold for conversion must be maintained in those with a cancer suspicion.

Laparoscopic cholecystectomy for porcelain gallbladder

UNLABELLED Between 1990 and 2006 in the III-rd Surgical Clinic Cluj-Napoca, 366 pacients with hepatic hydatid cyst were admitted and underwent surgery; 81 (22.13%) of them, who had a cyst-biliary comunication, were retrospectively reviewed: 52 (64.2%) had an occult communications and 29 (35.8%) had a frank intrabiliary rupture. The sex ratio was M/F=46/35 with a mean age of 44.5 years and with ages between 17 and 73 years. Choledochotomy, evacuation of parasitic material and lavage of the CBP were performed in all patients with frank intrabiliary rupture. In 25 patients, partial pericystectomy and choledochoduodenostomy/T-tube drainage of CBP was performed. Internal drainage by a Roux-en-Y pericystectojejunostomy and biliodigestive anastomosis was carried out in 2 patients, while other two patients underwent external drainage of cystic cavity and T-tube drainage of CBP. 15 patients (51.7%) had postoperative external bile leaks (fistulas). Occult communications were managed by partial pericystectomy +/- narrowing of the residual cavity (capitonage with an omentum flap or invagination of the fibrosis capsule margins into the cavity) in 35 patients (67.3%) while in 10 patients (19.2%) internal drainage by a Roux-en-Y pericystectojejunostomy was carried out. Regional resection of the liver was performed in 4 cases (7.7%) and external drainage of residual cavity in 3 patients (5.7%). 13 patients (25%) had postoperative external bile leaks (fistulas). The mean postoperative hospitalisation was 20 days with the range 5-85 days. The mortality rate was 2.4% (2 patients): one died due to septicemia and MOFS and the other due to pulmonary thromboembolism. CONCLUSION Postoperative bile leaks (fistulas) fallowing conservative surgery of ruptured hydatid hepatic cyst into the biliary tract are not rare regardless of the type of rupture (frank or occult). Although the opening of the biliary duct is sutured, the risk of biliary fistulas is not clearly corelated with this approach; in such cases internal drainage provides a good alternative with low morbidity.

Background: Even though laparoscopic cholecystectomy (LC) has become the customary method for treating gallstones, some incidents and complications appear rather more frequently than with the open technique. Several aspects of these complications and their treatment possibilities are analysed.Materials and Methods: Over the last 9 years 9542 laparoscopic cholecystectomies have been performed, of which 13.9% were carried out for acute cholecystitis, 38.4% in obese patients and 7.6% in patients aged > 65 years. Results: The main postoperative complications were bile leakage and choleperitoneum (54 cases), haemorrhage (15 cases), subhepatic abscess (10 cases) and retained bile duct stones (11 cases). Classic re-interventions were practiced in 28.8% of cases with complications. Mini-invasive techniques were used in 42.2% of cases with complications: laparoscopic re-interventions (15 cases) for choleperitoneum, haemoperitoneum and subhepatic abscess and endoscopic sphincterotomy (22 cases) for prolonge...
