Laparoscopic Cholecystectomy as a Day Surgery Procedure: Implementation and Audit of 136 Consecutive Cases in a University Hospital

Laparoscopic cholecystectomy (LC) has been routinely performed since 1989 at our institution, and patients were traditionally admitted for 2 days. In 1996 we implemented a protocol for LC as a day surgery procedure at our center. Although initially reported by others, it has not yet been introduced as routine in Switzerland. The objective of this prospective study was to determine acceptability and safety of LC as an outpatient procedure in a university hospital. Data were collected prospectively for 136 LCs between January 1996 and December 2001. Patients were selected for the study if they wanted to go home within less than 24 hours, had no previous jaundice, and had no anesthetic contraindication. Systematic preoperative liver function tests and hepatic ultrasonography were performed. All patients were admitted on the day of operation. LC was performed using a three-trocar technique. Systematic cholangiography was performed, and all the procedures were completed laparoscopically. There were no common bile duct explorations. Postoperative complications were the following: nausea in seven patients, a minor umbilical hematoma in two. According to patient preference, 101 (74%) were discharged after an overnight stay (less than 24 hours) and 32 (24%) on the same day. The unplanned admission rate was 2%, and none of the patients was subsequently readmitted. The reasons for unplanned admissions were two patients with persistent nausea and one patient for whom an overnight stay was scheduled who presented with a ruptured subcapsular hematoma of the liver. Altogether, 97% of the patients were satisfied with the care they received. Operative costs were not significantly different when comparing inpatient and outpatient LC. The main postoperative savings were in the postoperative costs. Our results confirm that LC as a day surgery procedure is safe, effective, and acceptable to patients and their relatives. These results were achieved by using selection criteria that considered not only the surgical pathology but also the individual and by using appropriate techniques and planned postoperative analgesi

Long-term Outcome after Liver Resection for Hepatocellular Carcinoma Larger than 10cm

Background: The purpose of the present study was to analyze long-term survival and disease-free survival after liver resection for giant hepatocellular carcinoma (HCC)≥10cm compared to HCC<10cm in diameter. The surgical approach in the treatment of giant HCC may achieve long-term survival and disease-free survival comparable to treatment of smaller lesions. Methods: This retrospective analysis was a monocentric study conducted in a tertiary university center. It included 101 patients from 114 consecutive liver resections for HCC, separated into two groups: those with tumors less than 10cm in diameter (small HCC; n=79) and those with tumors larger than 10cm (giant HCC; n=22). The main outcome measures were overall five-year survival, five-year disease-free survival, recurrence rate, perioperative mortality at 30days, surgical complication rate, and re-intervention rate. Results: The two groups were homogeneously distributed, apart from cirrhosis, which was found more frequently in the group with small HCC (77 vs. 41%; p=0.0013). Both median survival (24 vs. 27months; p=0.0085) and overall 5-year survival (21 vs. 45; p=0.04) were significantly poorer in the small HCC group compared to the giant HCC group. There were no differences en terms of recurrence rate, pattern, and timing. Conclusions: Liver resection for HCC larger than 10cm is a valuable option in selected patients, one that provides overall survival and disease-free survival comparable to smaller lesions. Functional reserves of the liver, more than the size of the lesion, may be important in patient selection for surgical resectio

Right Hepatectomy in Patients over 70 Years of Age: An Analysis of Liver Function and Outcome

Background: As a consequence of the increase in life expectancy, hepatobiliary surgeons have to deal with an emerging aged population. We aimed to analyze the liver function and outcome after right hepatectomy (RH) in patients over 70years of age. Methods: From January 2006 to December 2009, we prospectively collected data of 207 consecutive elective hepatectomies. In patients who had RH, cardiac risk was assessed by a dedicated preoperative workup. Liver failure (LF) was defined by the "fifty-fifty” criteria at postoperative day 5 (POD) and morbidity by the Clavien-Dindo classification. Liver function tests (LFTs) and short-term outcome were retrospectively analyzed in patients over (elderly group, EG) and younger (young group, YG) than 70years of age. Results: Eighty-seven consecutive RH were performed during the study period. Indication for surgery included 90% malignancy in 47% of patients requiring preoperative chemotherapy. ASA grade>2 (44 vs. 16%, p=0.027), ischemic heart disease (17 vs. 5%, p=0.076), and preoperative cardiac failure (26 vs. 2%, p<0.001) were more frequent in the EG (n=23) than in the YG (n=64). Both groups were similar regarding rates of normal liver parenchyma, chemotherapy and intraoperative parameters. The overall morbidity rates were comparable, but the serious complication (grades III-V) rate was relatively higher in the EG (39 vs. 25%, p=0.199), particularly in patients with diabetes mellitus (100 vs. 29%, p=0.04) and those who had additional nonhepatic surgery (67 vs. 35%, p=0.110) and transfusions (44 vs. 30%, p=0.523). The 90-day mortality rate was similar (9% in the EG vs. 3% in the YG, p=0.28) and was related to heart failure in the EG. LFTs showed a similar trend from POD 1 to 8, and patients ≥70years of age had no liver failure. Conclusions: Age ≥70years alone is not a contraindication to RH. However, major morbidity is particularly higher in the elderly with diabetes. This high-risk group should be closely monitored in the postoperative course. Liver function is not altered in the elderly patient after R

Laparoscopic management of appendicitis and symptomatic cholelithiasis during pregnancy

Background: Laparoscopic surgery during pregnancy is a challenging procedure that most surgeons are reluctant to perform. The objective of this study was to evaluate whether laparoscopic appendectomy and cholecystectomy is safe in pregnant women. The management of these situations remains controversial. We report a single center study describing the successful management of 16 patients during pregnancy. Methods: More than 3,356 laparoscopic procedures were performed in our institutions between May 1990 and June 2005. Sixteen of these patients were operated on in the second and third trimester between 22 and 32weeks of estimated gestational age. We performed 11 laparoscopic appendectomies and 5 laparoscopic cholecystectomies. We also reviewed the management and operative technique used in these patients. Results: In this study, the laparoscopic appendectomy or cholecystectomy was performed successfully in all patients. Three patients were in their second trimester, weeks22, 23, and 25, and 13 were in the third trimester, weeks27 (three patients), 28 (five patients), 31 (three patients), and 32 (two patients). No maternal or fetal morbidity occurred. Open laparoscopy was performed safely in all patients and all patients delivered healthy babies. Conclusion: From our experience laparoscopic management of appendicitis and biliary colic during pregnancy is safe, however the second trimester is preferable for laparoscopic cholecystectomy. Pregnancy is not a contraindication to the laparoscopic approach to appendicitis or symptomatic cholelithiasis. We believe that laparoscopic operations, when performed by experienced surgeons, are safe and even preferable for the mother and the fetu

Portal Vein Embolization: What Do We Know?

Portal vein embolization (PVE) has been developed to increase the size of the future remnant liver (FRL) left in place after major hepatectomy, thus reducing the risk of postoperative liver insufficiency. PVE consist in embolizing preoperatively portal branches of the segments that will be resected. Indication is based on preoperative measurements of the FRL by computed tomography and its ratio with either the theoretical liver volume or by direct measurement of the functional liver volume. After PVE, the volume and function of the FRL increases in 3 to 6weeks, permitting extensive resections in patients otherwise contraindicated for liver resection. The PVE technique is variable from one center to another; however n-butyl-cyano-acrylate provides an interesting compromise between hypertrophy rate and procedure ris

Survival after Lung Metastasectomy in Colorectal Cancer Patients with Previously Resected Liver Metastases

Background: Resection of hepatic metastases is indicated in selected stage IV colorectal cancer (CRC) patients. A minority will eventually develop pulmonary metastases and may undergo lung surgery with curative intent. The aims of the present study were to assess clinical outcome and identify parameters predicting survival after pulmonary metastasectomy in patients who underwent prior resection of hepatic CRC metastases. Methods: We performed a retrospective analysis of 27 consecutive patients (median age 62years; range: 33-75years) who underwent resection of pulmonary metastases after previous hepatic metastasectomy from CRC in two institutions from 1996 to 2009. All patients underwent complete resection (R0) for both colorectal and hepatic metastases. Results: Median follow-up was 32months (range: 3-69months) after resection of lung metastases and 65months (range: 19-146months) after resection of primary CRC. Three- and 5-year overall survival rates after lung surgery were 56 and 39%, respectively, and median survival was 46months (95% CI 35-57). Median disease-free survival after pulmonary metastasectomy was 13months (95% CI 5-21). At the time of last follow-up, seven patients (26%) had no evidence of recurrent disease and 6 of these 7 patients presented initially with a single lung metastasis. Conclusions: Resection of lung metastases from CRC patients may result in prolonged survival, even after previous hepatic metastasectomy. Yet, prolonged disease-free survival remains the exception, and seems to occur only in patients with a single lung lesio

Portal Vein Embolization before Right Hepatectomy: Improved Results Using n-Butyl-Cyanoacrylate Compared to Microparticles Plus Coils

Background: There is currently no consensus in the literature on which embolic agent induces the greatest degree of liver hypertrophy after portal vein embolization (PVE). Only experimental results in a pig model have demonstrated an advantage of n-butyl-cyanoacrylate (NBCA) over 3 other embolic materials (hydrophilic gel, small and large polyvinyl alcohol particles) for PVE. Therefore, the aim of this human study was to retrospectively compare the results of PVE using NBCA with those using spherical microparticles plus coils. Methods: A total of 34 patients underwent PVE using either NBCA (n=20), or spherical microparticles plus coils (n=14). PVE was decided according to preoperative volumetry on the basis of contrast-enhanced CT. Groups were compared for age, sex, volume of the left lobe before PVE and future remnant liver ratio (FRL) (volume of the left lobe/total liver volume−tumor volume). The primary end point was the increase in left lobe volume 1month after PVE. Secondary end points were procedure complications and biological tolerance. Results: Both groups were similar in terms of age, sex ratio, left lobe volume, and FRL before PVE. NBCA induced a greater increase in volume after PVE than did microparticles plus coils (respectively, +74±69% and +23±14%, p<0.05). The amount of contrast medium used for the procedure was significantly larger when microparticles and coils rather than NBCA were used (respectively, 264±43ml and 162±34ml, p<0.01). The rate of PVE complications as well as the biological tolerance was similar in both groups. Conclusion: NBCA seems more effective than spherical microparticles plus coils to induce left-lobe hypertroph

Post-traumatic pancreatico-dural fistula: Case report and management challenges

AbstractPancreatic injury can occur following high-energy blunt trauma to the torso. Although several types of pancreatic fistulas have been described in literature, we report to our knowledge, the first case of a pancreatico-dural fistula of traumatic origin.A 20-year-old male sustained a severe blow to the thoraco-abdominal region in the setting of a motorcycle accident. A total body scan revealed an AAST (American Association for the Surgery of Trauma) grade 4 splenic injury. A laparotomy with splenectomy and abdominal packing was performed. This was later followed by thoracolumbar instrumentation for posterior fixation of a T11–T12 transdiscal type C fracture with anterior subluxation of T11, according to the AO classification. Subsequent management was complicated by the persistence of a pseudomeningocele despite multiple surgical drainage procedures and a concomitant increase in retroperitoneal fluid collections. High levels of amylase and lipase in the pseudomeningocele fluid confirmed the presence of a pancreatico-dural fistula, due to a Wirsung duct rupture.This case report illiustrates the challenges in the management of this rare condition

Systematic hybrid laparoscopic and endovascular treatment of median arcuate ligament syndrome: A single-center experience

BackgroundMedian arcuate ligament syndrome (MALS) is caused by celiac trunk (CT) compression by the median arcuate ligament. Clinically, this pathology varies from postprandial pain (Dunbar syndrome) to a life-threatening hemorrhage because of a rupture of a gastroduodenal artery aneurysm (GAA). Due to the low prevalence of this disease, there is no standard management for MALS.Material and methodThis was a single-center, retrospective study of 13 patients. Two groups were identified on the basis of the initial clinical presentation: those operated for a GAA rupture (bleeding group—BG) and those operated electively for Dunbar syndrome (Dunbar syndrome group—DG). The primary endpoint was 30-day postoperative complications of a systematic laparoscopic release of the median arcuate ligament and stenting during the same procedure.ResultsSeven patients (54%) underwent elective surgery. Six patients (46%) underwent semiurgent repair under elective conditions post-embolization for GAA bleeding. The total operative time was longer in the BG (p = 0.06). Two patients in the BG suffered early major complications and needed reintervention, and those in the DG had a lower comprehensive complication index. No mortality was reported at 30 days. Overall median length of stay was 5 days (IQR: 3.5–15.3). Patients in the DG had a significantly shorter length of stay (p = 0.02). At 6 months, the primary and secondary CT stent patencies were 82% and 100%, respectively. There were no high-flow GAA recurrences.ConclusionsA combined approach of laparoscopic release of the median arcuate ligament and stenting during the same procedure is feasible and safe, and this approach must be systematically discussed in symptomatic patients
