Hepatic parenchymal transection using ultrasonic coagulating shears: a preliminary report

Ultrasonically activated coagulating shears (CS) can coagulate and divide blood vessels of up to medium size by a tissue‐welding technique. We present an application of CS in hepatic parenchymal transection during liver surgery. Intrahepatic vessels are uncovered by the so‐called forceps fracture method, and they are coagulated and divided by CS. Larger vessels are tied only on the preserving side before the application of CS. Although further refinement of the CS tip is needed, this method has the potential to significantly simplify and improve surgical procedures for hepatic parenchymal transection.     

Laparoscopic Nissen fundoplication: results and prognostic factors

Introduction: Laparoscopic Nissen fundoplication is the technique of choice in the surgical treatment of gastroesophageal reflux disease. Aims: To review the cases of laparoscopic Nissen fundoplication carried out at our hospital and to analyze the prognostic factors that influenced surgical outcome. Material and methods: A total of 226 patients that underwent laparoscopic Nissen fundoplication within the time frame of 1996 to 2010 were retrospectively reviewed. Surgical results and prognostic factors were evaluated in 182 patients that had a follow-up longer than one year. Results: The Nissen-Rossetti technique was carried out in 219 patients, without short gastric vessel division, and the "floppy"-Nissen technique was performed on seven patients. Intraoperative complication rate was 3.1%, conversion rate was 6.6%, and postoperative complication rate was 4%. Mortality was 0. After surgery, 19% of patients presented with dysphagia that was persistent in only 3.5%. Of the 182 patients with a follow-up longer than one year, 166 (91.2%) were satisfied with the surgical results. In the univariate analysis, esophagitis (OR=0.59) was a protective factor, while a DeMeester score >50 (OR=1.97) and medical treatment resistance (OR=1.75) were risk factors. In the multivariate analysis a DeMeester score >50 (OR=4.24) was the only independent prognostic factor associated with poor outcome. Conclusions: Our results with laparoscopic Nissen fundoplication are comparable to those found in the medical literature, with a high degree of patient satisfaction. Esophagitis is associated with good outcome, while massive reflux and medical treatment resistance are negative prognostic factors.     

Laparoscopic hepatectomy with the hook blade of ultrasonic coagulating shears and bipolar cautery with a saline irrigation system

Background

The number of patients who have undergone laparoscopic hepatectomy is small, and the operative procedure is not yet well established.

Methods

We performed laparoscopic hepatectomy in eight patients, using the hook blade of ultrasonic coagulating shears, and bipolar cautery with a saline irrigation system, with minilaparotomy. The operative time, blood loss, and postoperative hospital stay of patients with laparoscopic left lateral segmentectomy were compared with these parameters in ten patients who had had a left lateral segmentectomy with laparotomy.

Results

The laparoscopic hepatectomies included seven left lateral segmentectomies and one nonanatomical partial resection of the lateral segment. The mean duration of the operation in these eight patients was 181.1 ± 44.6?min. The mean amount of blood loss was 177.6 ± 129.1?ml. Postoperative complications consisted of two cases of bleeding. The mean postoperative hospital stay in all eight patients was 9.88 ± 4.36 days. The mean duration of operation (185.9 ± 46.0?min) and mean postoperative hospital stay (9.47 ± 4.61 days) in the seven patients with laparoscopic left lateral segmentectomies were significantly shorter than these parameters (255.7 ± 59.4?min and 24.6 ± 8.82 days) in the ten patients who had had left lateral segmentectomies with laparotomy. The mean amount of blood loss (160.0 ± 128.9?ml) in the laparoscopic series was less than that (318.5 ± 192.2 days) in the patients who had had laparotomy.

Conclusions

Laparoscopic hepatectomy with the ultrasonic coagulating shears and bipolar cautery with minilaparotomy was safe, and less invasive than the open procedure, for minor hepatectomy procedures such as left lateral segmentectomy.

Nissen fundoplication in infants and children: a long-term clinical study

BACKGROUND/AIMS: Infants and children who underwent open Nissen fundoplication for gastroesophageal reflux disease were retrospectively evaluated to assess the success and complications of this operation. METHODOLOGY: Twenty-six neurologically normal children (16 boys and 10 girls between 6 months and 11 years old) underwent Nissen fundoplication for intractable or complicated gastroesophageal reflux between October 1982 and February 2002. Before surgery and at follow-up visits, all children were subjected to thorough history, barium meal study and gastroscopy with multiple esophageal biopsies. The median follow-up period was 28 months (range: 11 months-19 years). RESULTS: Persistent vomiting or regurgitation since birth was the main symptom (24 patients, 92.3%), chest symptoms occurred in 5 patients (19.2%), malnutrition and retarded growth were found in 4 patients (15.4%), hematemesis and/or melena occurred in 2 patients (7.7%) and dysphagia due to esophageal stricture occurred in 4 patients (15.4%). There was no mortality. The mean hospital stay was 4.1 days. Twenty-two patients (84.6%) had no recurrent reflux. Reflux symptoms recurred in 4 cases (15.4%). One of these cases had no evidence of recurrent pathological reflux, 2 cases with preoperative stricture developed wrap disruption, recurrent reflux and re-stricture. Both refused a second operation. The fourth case developed melena and reflux esophagitis due to wrap herniation through the hiatus and was successfully managed by a second operation. CONCLUSIONS: Nissen fundoplication is an effective operation to correct gastroesophageal reflux in infants and children when the drug therapy fails. The operation should be done before occurrence of complications to decrease the recurrence of reflux.     

Revision of failed transoral incisionless fundoplication by subsequent laparoscopic Nissen fundoplication

AIM:To evaluate the feasibility and outcomes of laparoscopic Nissen fundoplication after failed transoral incisionless fundoplication(TIF).METHODS:TIF is a new endoscopic approach for treating gastroesophageal reflux disease(GERD).In cases of TIF failure,subsequent laparoscopic fundoplication may be required.All patients from 2010 to 2013 who had persistence and objective evidence of recurrent GERD after TIF underwent laparoscopic Nissen fundoplication.Primary outcome measures included operative time,blood loss,length of hospital stay and complications encountered.RESULTS:A total of 5 patients underwent revisional laparoscopic Nissen fundoplication(LNF)or gastrojejunostomy for recurrent GERD at a median interval of 24mo(range:16-34 mo)after TIF.Patients had recurrent reflux symptoms at an average of 1 mo following TIF(range:1-9 mo).Average operative time for revisionalsurgical intervention was 127 min(range:65-240 min)and all surgeries were performed with a minimal blood loss(<50 m L).There were no cases of gastric or esophageal perforation.Three patients had additional finding of a significant hiatal hernia that was fixed simultaneously.Median length of hospitalization was 2 d(range:1-3 d).All patients had resolution of symptoms at the last follow up.CONCLUSION:LNF is a feasible and safe option in a patient who has persistent GERD after a TIF.Previous TIF did not result in additional operative morbidity.     

The economics of laparoscopic Nissen fundoplication.

BACKGROUND & AIMS: A major impetus for laparoscopic Nissen fundoplication (LNF) is its purported cost savings compared with medical therapy, but few studies have examined these economic outcomes. The aim was to analyze health care costs and use among a cohort of patients undergoing LNF and compare them with patients with medically treated gastroesophageal reflux disease (GERD). METHODS: Comparison of health care use and direct costs from the third-party payer perspective using 13 United HealthCare Plans. Sixty-one patients who underwent LNF from January 1994 to June 1998 and 178 matched controls were used for this study. Outcome variables included the cost of hospital and outpatient visits, hospitalizations, related endoscopic procedures, and pharmacy claims for proton pump inhibitors, H(2) receptor antagonists, and prokinetics. Cost of LNF or index esophagogastroduodenoscopy was not included. RESULTS: Sixty-one LNF patients and 178 controls were studied. No differences were seen for the costs of office visits and hospital admissions or the number of gastrointestinal procedures. LNF patients had significantly lower gastrointestinal medication costs. Median total health care costs were significantly lower in the LNF group but mean total costs were not different. This was attributable to $201,000 in costs for managing complications in one patient that skewed total health care cost in the LNF group. CONCLUSIONS: For the 12 months after surgery, LNF reduced costs for gastrointestinal medications but not total costs for the cohort. LNF cost is impacted greatly by the cost of associated complications. Based on these data, LNF does not appear to significantly reduce the direct cost of health care for GERD patients on a population basis.     

Outcome of erosive reflux esophagitis after Nissen fundoplication

OBJECTIVE: The aim of this study was to compare the utilization of health care resources and long term outcome of erosive esophagitis in patients treated with and without open Nissen fundoplication. METHODS: A population of 35,725 patients with erosive esophagitis was extracted from the computerized database of the US Department of Veterans Affairs. Subjects were stratified by severity of disease into erosive esophagitis alone versus erosive esophagitis complicated by esophageal ulcers or peptic strictures. During a mean follow-up period of 4.2 yr (range 1-12 yr), the consumption of health care resources, except for medications, was compared between case and control subjects treated with and without fundoplication, respectively. RESULTS: Among patients with complicated erosive esophagitis, 5,064 control subjects were treated without, and 542 case subjects were treated with, fundoplication. Cases incurred less recurrence of esophageal erosions (controls: 56% vs cases: 46%), esophageal ulcers (38% vs 33%), and peptic strictures (43% vs 32%) during follow-up. Among patients with erosive esophagitis but no complications, 29,514 control subjects were treated without, and 605 case subjects were treated with, fundoplication. Cases did not experience any change in the recurrence of esophageal erosions (controls: 25% vs cases: 24%). Irrespective of treatment type, none of the case or control subjects with erosive esophagitis alone developed esophageal ulcers or peptic strictures during follow-up. Compared with controls, however, after fundoplication in erosive esophagitis alone, cases incurred more dysphagia (2.6% vs 4.6%), postsurgical syndromes (0.8% vs 1.7%), as well as more outpatient visits (34 vs 40 visits/patient) and outpatient procedures (2.7 vs 4.3 procedures/patient). CONCLUSIONS: Fundoplication improves the clinical outcome of erosive esophagitis in patients with concomitant esophageal ulcers and strictures, but not in patients without such complications. Fundoplication does not reduce the consumption of health care resources.     

Duodenum-preserving resection of the pancreatic head with the ultrasonic coagulating shears

Duodenum-preserving resection of the pancreatic head is a risk factor for pancreatic fistula because of the wide surface of the transected pancreas. We report on a 72-year-old woman undergoing this procedure for cystadenoma in the pancreatic head using the ultrasonic coagulating shears. The soft pancreatic parenchyma was extensively transected around the cyst with the coagulating shears. Suture of the cut stump was not necessary due to absence of bleeding. The distal pancreatic duct was well preserved for pancreatojejunostomy. We oversewed the possible opening of the main pancreatic duct on the remaining pancreas attached to the duodenum after confirming the location by intrabiliary dye injection. The postoperative course was uneventful. The draining fluid amylase level was low and there were no viscous materials from the drains. We compared histologic changes of a porcine pancreas transected with the coagulating shears or electrocautery to evaluate the sealing effect of the transected surface. The cut stump was covered by a continuing layer of thick protein coagulum in cases of coagulating shears, but by a disrupted layer of coagulating necrosis with charring in cases of electrocautery. The coagulating shears are useful for pancreatic transection in duodenum-preserving resection of the pancreatic head to prevent bleeding and pancreatic fistula from the cut surface.
