Preoperative portal vein embolization for major liver resection: a meta-analysis.

Introduction:Preoperative portal vein embolization (PVE) is used clinically to prevent postoperative liver insufficiency. The current study examined the impact of portal vein embolization on liver resection. Method:A comprehensive Medline search to identify all registered literature in the English language on portal vein embolization. Meta-analysis was performed to assess the result of PVE and its impact on major liver resection. Result:A total of 75 publications met the search criteria but only 37 provided data sufficiently enough for analysis involving 1088 patients. The overall morbidity rate for PVE was 2.2% without mortality. Four weeks following PVE, 85% patients underwent the planned hepatectomy (n = 930). Twenty-three patients had transient liver failure following resection after PVE (2.5%) but 7 patients developed acute liver failure and died (0.8%). The reason for nonresection following PVE (n = 158, 15%) included inadequate hypertrophy of remnant liver (n = 18), severe progression of liver metastasis (n = 43), extrahepatic spread (n = 35), refusal to surgery (n = 1), poor general condition (n = 1), altered treatment to transcatheter artery embolization or chemotherapy (n = 24), complete remission after treatment with 3 cycles of fluoracil and interferon α in a patient with hepatocellular carcinoma (n = 1), incomplete pre- or postembolization scanning (n = 8). Of those who underwent laparotomy without resection, (n = 27) reasons included intraoperative finding of peritoneal dissemination (n = 15), portal node metastasis (n = 2), severe invasion of the tumor to the hepatic artery and portal vein (n = 1), and gross tumoral extension precluding curative resection (n = 9). Two techniques were used for portal vein embolization: percutaneous transhepatic portal embolization, (PTPE) and transileocolic portal embolization, (TIPE). The increase in remnant liver volume was much greater in PTPE than TIPE group (11.9% vs. 9.7%; P = 0.00001). However, the proportion of patients who underwent resection following PVE was 97% in TIPE and 88% PTPE, respectively (P = <0.00001). Although there was no significant difference in patients who had major complications post-PVE, the rate for minor complications was significantly higher among patients who had PTPE (53.6% vs. 0%, P = <0.0001). Conclusion:PVE is a safe and effective procedure in inducing liver hypertrophy to prevent postresection liver failure due to insufficient liver remnant.

Management of Delayed Postoperative Hemorrhage After Pancreaticoduodenectomy : A Meta-analysis

OBJECTIVE To determine whether interventional radiology (IR) or laparotomy (LAP) is the best management of delayed postoperative hemorrhage (DPH) after pancreaticoduodenectomy. Data Source We undertook an electronic search of MEDLINE and selected for analysis only original articles published between January 1, 1990, and December 31, 2007. STUDY SELECTION Two of us independently selected studies reporting on clinical presentation and incidence of postoperative DPH and the following outcomes: complete hemostasis, morbidity, and mortality. DATA EXTRACTION Two of us independently performed data extraction. Data were entered and analyzed by means of dedicated software from The Cochrane Collaboration. A random-effects meta-analytical technique was used for analysis. DATA SYNTHESIS One hundred sixty-three cases of DPH after pancreaticoduodenectomy were identified from the literature. The incidence of DPH after pancreaticoduodenectomy was 3.9%. Seventy-seven patients (47.2%) underwent LAP; 73 (44.8%), IR; and 13 (8%), conservative treatment. On meta-analysis comparing LAP vs IR for DPH, no significant difference was found between the 2 treatment options for complete hemostasis (73% vs 76%; P = .23), mortality (43% vs 20%; P = .14), or morbidity (77% vs 35%; P = .06). CONCLUSIONS This meta-analysis, although based on data from small case series, is unable to demonstrate any significant difference between LAP and IR in the management of DPH after pancreaticoduodenectomy. The management of this life-threatening complication is difficult, and the appropriate treatment pathway ultimately will be decided by the clinical status of the patient and the institution preference.

Laparoscopic redo surgery for recurrent hepatocellular carcinoma in cirrhotic patients: feasibility, safety, and results

BackgroundRecurrence of cancer and the need for several surgical treatments are the Achilles’ heel of the treatment for hepatocellular carcinoma (HCC) in cases of cirrhosis. The difficulty of reintervention is increased by the formation of adhesions after the previous hepatectomy that can make a new surgical procedure more difficult and less safe. With a minimally invasive approach, the formation of postoperative adhesions seems to be minimized, and the adhesiolysis procedure seems to be faster and safer in terms of blood loss and risk of visceral injuries.MethodsThis report describes a series of 15 patients submitted to a laparoscopic reintervention (hepatic resection or radiofrequency ablation) for a recurrence of HCC after a previous open (group 1) or laparoscopic (group 2) procedure for a primary tumor. It aims to explain the feasibility, safety, and results of repeated laparoscopic liver surgery.ResultsThe rates for overall postoperative mortality and morbidity were respectively 0% and 26.6% (4/15). No patients had a severe postoperative complication. Only one patient in group 2 presented with moderate ascites postoperatively, whereas two patients in group 1 reported atelectasis requiring physiotherapy and one experienced pneumonia, which was treated with antibiotics. In this series, the findings indicated that patients submitted first to an open hepatic resection (group 1) experience more intraabdominal adhesions. Moreover, in group 1, hypervascularized adhesions typical of cirrhotic patients were several and thicker, with a major potential risk of bleeding and bowel injuries at the time of reintervention. Although for group 2 the length of the intervention was shorter, for group 1, the operating times and safety in terms of bowel injuries were acceptable, demonstrating the feasibility of iterative laparoscopic surgery also for cirrhotic patients previously treated by the open surgical approach. The operative time for the second surgical procedure was shorter and the adhesiolysis easier for the patients previously treated with the laparoscopic approach (group 2). This underscores the advantages of the minimally invasive approach for managing the long oncologic history of cirrhotic patients.ConclusionLaparoscopic redo surgery for recurrent HCC in cirrhotic patients is a safe and feasible procedure with good short-term outcomes, but further prospective studies are needed to support these results.

Laparoscopic Liver Resection for Hepatocellular Carcinoma in Cirrhosis: Long-Term Outcomes

Background:Few data regarding survival or pattern of recurrence after laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) on cirrhosis have been reported so far. Methods: A retrospective analysis of a prospectively maintained database of 109 laparoscopic interventional procedures performed for HCC in cirrhotic liver between 2000 and 2008 was conducted. Results: Sixty-five patients underwent an LLR. Morbidity rates were 20% (13/65), whereas there was only 1 death (1.5%). Reoperation was required in 2 patients. The overall mean postoperative hospital stay was 8.2 (2.6; 3–15) days. The actuarial overall 1-, 3-, and 5-year survival rates were 95, 70, and 55%, respectively, with a median overall survival of 75 months. Excluding the one hospital death, the actuarial 1-, 3-, and 5-year disease-free survival rates were 81, 62, and 32%, respectively, with a median overall disease-free survival of 42 months (95% confidence interval, CI: 18–65). On multivariate analysis, tumor grade (OR: 3.5, 95% CI: 1.1–10.7, p = 0.026) and microvascular invasion (OR: 4.9, 95% CI: 1.2–18.8, p = 0.020) resulted as independent predictors of overall survival. On multivariate analysis, gender (OR: 3.4, 95% CI: 1.1–10.2, p = 0.023), satellite tumor (OR: 4.3, 95% CI: 1.5–12.3, p = 0.006), microvascular invasion (OR: 3.3, 95% CI: 1.0–10.1, p = 0.036) and surgical margin (OR: 3.7, 95% CI: 1.0–10.1, p = 0.036) were identified as independent prognostic predictors of better disease-free survival. After a median follow-up of 29 (range 3–81) months, 31 (48%) out of 64 patients had recurrence. The cumulative recurrence rates at 1, 3, and 5 years were 19, 39, and 68%, respectively. Conclusion: This prospective observational study has confirmed the feasibility and safety of LLR in selected patients with HCC in cirrhotic liver, and proved that it can warrant long-term outcome similar to those reported with the traditional open approach.

Association between persistent symptoms and long-term quality of life after laparoscopic total fundoplication

BACKGROUND We investigated which factors are significantly associated with long-term quality of life after laparoscopic total fundoplication in the treatment of gastroesophageal reflux disease. METHODS Patients (n = 144) were given a standardized frequency-intensity symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication. RESULTS At follow-up evaluation (n = 102), patients had a significant reduction in their symptoms score and no deterioration in quality of life. A significant association with postoperative dysphagia for solids and/or liquids was found in the physical component summary score of the Short-Form 36 administered to patients postoperatively (P = .003). CONCLUSIONS In this study, laparoscopic total fundoplication was a safe and effective surgical treatment for gastroesophageal reflux disease, generally offering an improved long-term quality of life, with the exception of a minority of patients (6 of 102 patients; 5.8%) who experienced persistent severe dysphagia.

Laparoscopic Nissen-Rossetti fundoplication with routine use of intraoperative endoscopy and manometry: technical aspects of a standardized technique.

BackgroundSeveral different ways of fashioning a total fundoplication lead to different outcomes. This article addresses the technical details of the antireflux technique we adopted without modifications for all patients with GERD beginning in 1972. In particular it aims to discuss the relation between the mechanism of function of the wrap and the physiology of the esophagus.MethodsThe study population consisted of 380 patients affected by GERD with a 1-year minimum of follow-up who underwent laparoscopic Nissen-Rossetti fundoplication by a single surgeon.ResultsNo conversion to open surgery and no mortality occurred. Major complications occurred in 4 patients (1.1%). Follow-up (median 83 months; range: 1–13 years) was achieved in 96% of the patients. Ninety-two percent of the patients were satisfied with the results of the procedure and would undergo the same operation again. Postoperative dysphagia occurred in 3.5% of the patients, and recurrent heartburn was observed in 3.8%.ConclusionsLaparoscopic Nissen-Rossetti fundoplication with the routine use of intraoperative manometry and endoscopy achieved good outcomes and long-term patient satisfaction with few complications and side-effects. Appropriate preoperative investigation and a correct surgical technique are important in securing these results.

Laparoscopic Segment VI Liver Resection using a Left Lateral Decubitus Position: A Personal Modified Technique

BackgroundLaparoscopic technique for lesions located in the left liver is well described in the literature. On the contrary, the best laparoscopic approach for lesions located in the right liver, such as in segment VI, is still debated.AimIn this article, we provide a detailed description of a laparoscopic segment VI liver resection using a left lateral decubitus position with the right side up, facilitated by a personal technique. We also discuss potential advantages and disadvantages of this procedure.

Useful parameters helping proctologists to identify patients with defaecatory disorders that may be treated with pelvic floor rehabilitation

BackgroundNo studies have specifically reported on the use of a diagnostic tool based on physiatric assessment of constipated or incontinent patientsMethodsSixty-seven constipated and 37 incontinent patients were submitted to a standard protocol based on proctologic examination, clinico-physiatric assessment (puborectalis contraction, pubococcygeal test, perineal defence reflex, muscular synergies, postural examination) and instrumental evaluation (anorectal manometry, anal US and dynamic defaecography). Patients were offered pelvic floor rehabilitation (thoraco-abdominoperineal muscle coordination training, biofeedback, electrical stimulation and volumetric rehabilitation).ResultsAfter rehabilitation treatment, decreases of Wexner constipation score (p=0.0001) and Pescatori incontinence score (p=0.0001) were observed.ConclusionThis diagnostic protocol might improve the selection of patients with defaecatory disorders amenable for rehabilitation treatment.

Gastroesophageal reflux disease and obesity: do we need to perform reflux testing in all candidates to bariatric surgery?

INTRODUCTION Obesity is a strong independent risk factor of gastroesophageal reflux disease (GERD) symptoms and esophageal erosions. However the relationship between obesity and GERD is still a subject of debate. In fact, if in most cases bariatric surgery can diminish reflux by losing a large amount of fat, on the other hand some restrictive procedure can worsen or cause the presence of GERD. Thus, it is unclear if patients candidate to bariatric surgery have to perform pre-operative reflux testing or not. AIM of the study was to verify the presence of GERD patterns in patients candidate to surgery and the need of pre-operative reflux testing. METHODS All patients underwent to a standardized questionnaire for symptoms severity (GERQ), upper endoscopy, high resolution manometry (HRiM) and impedance pH-monitoring (MII-pH). Patients were stratified into: group 1 (negative for both GERQ and endoscopy), group 2 (positive for GERQ and negative for endoscopy), group 3 (positive for both GERQ and endoscopy). A healthy-volunteers group (HV) was assessed. RESULTS One hundred thirty-nine subjects (obese, 124; HV normal weight, 15) were studied. Group 1 showed comparable mean LES pressure, peristaltic function, bolus transport and presence of hiatal hernia than HV. Group 2 showed a reduction of these parameters, while group 3 showed a statistical significant reduction in LES pressure, peristaltic function, bolus transport and increase in presence of hiatal hernia. At MII-pH, Group 1 showed a not significant increase in reflux patterns; group 2 and 3 showed a significant increase in esophageal acid exposure and in number of refluxes (both acid and weakly acid), with group 3 showing the higher grade of reflux pattern. CONCLUSIONS Obese subjects with pre-operative presence of GERD symptoms and endoscopical signs could be tested with HRM and MII-pH before undergoing bariatric surgery, especially for restrictive procedures. On the other hand, obese patients without any sign of GERD could not be tested for reflux, showing similar patterns to HV.

Sleeve gastrectomy improves obstructive sleep apnea syndrome (OSAS): 5 year longitudinal study

BACKGROUND Obstructive sleep apnea syndrome (OSAS) is prevalent among morbidly obese patients. Evaluation of the specific effects of sleeve gastrectomy (SG) on upper airway function has not been reported. Given the possibility that some patients will not respond despite weight loss, no studies have investigated whether other mechanisms may be responsible for persistent OSAS after bariatric surgery. OBJECTIVES To evaluate by subjective and objective assessment the impact of SG on upper respiratory physiology in the long-term. SETTING University Hospital, Division of Bariatric and ENT Surgery, in Italy. METHODS Thirty-six consecutive patients with OSAS who underwent laparoscopic SG were prospectively enrolled. The effect of SG on respiratory function and OSAS was followed for 5 years. RESULTS All patients completed the 5-year follow-up. A significant (P<.001) improvement in modified Epworth Sleepiness Scale questionnaire (ESS) was obtained in 91.6% (33/36) of patients. The Apnea/Hypopnea index (AHI) improved in 80.6% (29/36) of patients after surgery (from 32.8 ± 1.7 to 5.8 ± 1.2 (P<.001), 4.9 ± 1.7). The remaining 19.4% (7/36) of patients with a positive ESS and/or AHI all had an associated respiratory resistance due to nasal obstructive diseases. CONCLUSION SG improved OSAS overall, but patients who did not improve or only partially improved despite weight loss were found to have an associated nasal responsible pathology. How these patients will respond to nasal surgery and whether a 2-step procedure should be recommended for OSAS patients requires further study.
