ABSTRACT: Laparoscopic sleeve gastrectomy (LSG) is performed in certain circumstances after failure of gastric banding. The goal of this study was to evaluate the impact of first-line gastric banding on the morbidity associated with secondary LSG for obesity.
The case records of 102 consecutive patients undergoing LSG were studied retrospectively. The technique of LSG was standardized. Two groups were compared: one with patients having undergone LSG after first-line gastric banding (n = 31) and the second, with patients having undergone first-line LSG (n = 71). Endpoints were overall morbidity and intra/postoperative complications including gastric leaks consecutive to staple line disruption as well as other septic or hemorrhagic complications. Multivariable analysis was performed to detect independent risk factors for morbidity.
Overall morbidity was significantly higher in patients having undergone LSG after first-line gastric banding compared with those undergoing first-line LSG (32.2% vs. 7%, P = 0.002). Gastric leaks secondary to staple line disruption also occurred statistically significantly more often in patients with first-line gastric banding (16.1% vs. 2.8%, P = 0.043). Waiting 6 months between gastric band removal and performing LSG did not prevent the increased morbidity compared with first-line LSG. Multivariable analysis revealed that among the factors analyzed (age, gender, comorbidity, body mass index, surgeon, first-line gastric banding), the only independent risk factor for staple line disruption was first-line gastric banding with an odds ratio = 6.6 (95% confidence interval = [1.2-36.3]).
Undergoing first-line gastric banding increases the risk of complications after secondary LSG. We recommend that patients who undergo LSG after a first-line gastric banding should be warned of the increased risks of morbidity or, alternatively, that LSG be performed preferentially as the initial procedure.

ABSTRACT: In most cases, fibrolamellar hepatocellular carcinoma has specific and distinctive histopathological features that distinguish it from hepatocellular carcinoma. Magnetic resonance imaging can provide characteristic features to obtain a diagnosis of this entity. We report a case of fibrolamellar hepatocellular carcinoma with a radiological-pathological correlation in a 37 year-old man with chronic viral hepatitis B without cirrhosis who underwent right hepatectomy.

ABSTRACT: The timing of elective surgery of colonic diverticulitis in young patients remains controversial. The present meta-analysis aimed to answer the question whether these patients should be operated after the first attack or, more classically, after the second attack.
Electronic databases were searched for papers reporting the results of surgery according to the strategies. Major endpoint was the performance of a colostomy (during unplanned surgery or for anastomotic dehiscence complicating elective surgery).
Fifteen papers were selected for potential inclusion in the meta-analysis. But, eventually, only three papers gave information about the timing of surgery. Pooling the data of these 3 studies showed that 160 patients underwent elective surgery after the first attack and only 5 patients underwent subsequent emergent surgery at the course of their disease. Hence, no meta-analysis could be performed.
Researchers should no longer attempt (like us) to answer this question by any meta-analysis. The failure of the present meta-analysis highlights the limitations of evidence-based surgery in some particular fields.

ABSTRACT: To evaluate the magnitude of the morbidity related to the system used for gastric banding Methods Between January 1997 and December 2004, 286 consecutive patients underwent laparoscopic gastric banding (LAGB) in one center. We used 4 models of LapBand 9.75, 10, 11 and Vanguard with pars flacida route. Recalibration of band was performed in our consultation unit without systematic radiologic control. We considered four kinds of complication: port displacement, port rupture, band rupture and others problems.
The mean follow up was 3.3+/-2.8 years with a median 2.9 years. Complications occurred within a mean time of 2.2+/-1.9 years. For the models vanguard and size 11, there were no rupture and 15 (27.7%) displacements whereas for size 9.75 and 10 there were 39 ruptures (14.7%) and 15 (5.6%) displacements. Types of complications were related to the bands used i.e. more port displacements for the models vanguard and size 11 and more band and port ruptures for the models size 9.75 and 10. But when we considered the respective follow up according to the type of band these differences were no longer significant. Moreover rupture rate was significantly high but decreased after March 2002 because of changing of junction between port and catheter. Mean excess weight loss (35.2+/-27.7%) was not different in group whether the patients were reoperated or not.
Band and port related morbidity is an important aspect of bariatric surgery. We have to pay attention to material evolution and to our follow up for calibration. Some new recent technical advancement could improve the management of these patients.

ABSTRACT: The interest in geriatric surgery is on the increase because of the ageing of the population. Our study reviewed the results of a non- specialised unit. Method 54 octogenarians underwent digestive surgery including visceral resection. Cancer predominated the indications (80%).
The patients exhibited cardiovascular (87%), endocrine (18.5%) or neuropsychiatric (29.6%) disorders with 75% scoring ASA III or IV. Morbidity was of 81.5% with 20% of specifically surgical complications and a 40.2% rate of cardiovascular complications. Post-surgical mortality was of 7.4% and the survival rate at 2 years was of 44.4%. The treating physicians judged that in 65% of patients the intervention had improved the initial status of the patient and had stabilised the disease in 35% of cases. The percentage of patients living at home declined from 83.3% before the intervention to 64.8% after the intervention. Only 2 out of the 9 patients having undergone stomy of the colon following colectomy continued to improve.
This study underlines the interest of major surgery in octogenarians, including in units non-specialised in geriatric surgery.

ABSTRACT: Mechanical bowel preparation is used routinely before colorectal surgery, but some randomized clinical trials have suggested that it is of no benefit. This study assesses whether such bowel preparation may safely be omitted before elective colorectal surgery.
A search of the literature was performed; the inclusion criteria were randomized clinical trials comparing bowel preparation with no preparation in colorectal surgery. The methodological quality of included trials was assessed. The primary outcome was anastomotic leakage; secondary outcomes were other septic complications. The meta-analysis was conducted using the Peto one-step method.
Eleven trials were retrieved, of which seven, containing 1454 patients, were included in the meta-analysis. There was no heterogeneity between the trials. Significantly more anastomotic leakage was found after mechanical bowel preparation (5.6 versus 3.2 per cent; odds ratio 1.75 (95 per cent confidence interval 1.05 to 2.90); P = 0.032). All other endpoints (wound infection, other septic complications and non-septic complications) also favoured the no-preparation regimen, but the differences were not statistically significant. Sensitivity analysis showed that these results were similar when trials of poor quality were excluded. Subgroup analysis showed that anastomotic leakage was significantly greater after bowel preparation with polyethylene glycol (PEG) compared with no preparation, but not after other types of preparation.
There is good evidence to suggest that mechanical bowel preparation using PEG should be omitted before elective colorectal surgery. Other bowel preparations should be evaluated by further large randomized trials.

ABSTRACT: The use of bipolar scissors (PowerStar) which has been suggested to reduce bleeding during surgical dissection, involves the theoretical risk for increasing intraperitoneal adhesions because of burn damages to the peritoneum secondary to bipolar electrocautery.
Thirty-six white new-Zealand rabbits have been included in a double-blind randomised trial to undergo a laparotomy using either a sharp scissors with on-demand monopolar coagulation or a bipolar scissors. Operatives procedures were standardised: midline laparotomy (5 cm), mobilisation of the right colon, incision of the colonic serosa without suture, incision of the colonic serosa with running sutures, incision of the mesentery. All these steps were performed by the same device according to the randomisation. Ten days later, the rabbits were killed. Adhesions were measured and scored according to the Zühlke classification by a surgeon who was not aware of the type of scissors used. Finally a pathological examination of adhesion was randomly performed.
The two groups were similar for weight and sex-ratio. Two rabbits died before the tenth postoperative day (1 unknown aetiology and 1 evisceration). 34 rabbits were available for the study (18 in the "PowerStar" group and 16 in the control group). The results showed no significant difference between the groups for all measured endpoints (length and score of intraperitoneal and parietal adhesions). Nevertheless, pathological examination showed the burn damages to be less pronounced after using PowerStar.
Bipolar scissors do not increase postoperative adhesions in the rabbit and probably induce less burn damages than monopolar cautery. The additional advantage i.e. the decrease adhesions formation, because of a less intraperitoneal bleeding, has not been observed in this randomised trial.

ABSTRACT: The relationship between volume and surgical outcome seems logical, but needs to be demonstrated in the real world. A qualitative systematic review has been conducted to verify this hypothesis. Five systematic reviews and hundred original papers have been retrieved and analysed. Most of the studies were retrospective and used administrative data instead of medical charts. Moreover few studies involved a good case mix adjustment when comparing surgical units or individual surgeons. These methodological flaws do not allow any evidence based conclusions. Even though a positive relationship is suggested for surgical units, the relationship between volume and outcome was however less obvious for an individual surgeon. There is some evidence that the relationship varied greatly according to the specialty or the procedure evaluated. A new approach based on predictive scores comparing expected versus observed outcomes is mandatory and seems to be the best way to assess objectively the relationship between surgical volume and outcomes.

ABSTRACT: Major complications following pancreaticoduodenectomy are thought to be chiefly associated with exocrine secretion of the pancreatic remnant which is not well known. This work aims to assess the exocrine secretion of the pancreatic remnant within the early post-operative period.
Seventy-five patients undergoing pancreaticoduodenectomy for presumed tumour were included in a prospective multicentre study. A tube was inserted in the pancreatic duct at the time of construction of the pancreatic anastomosis. Peripancreatic drainage was routinely used. Pancreatic juice and peripancreatic drainage fluid were collected and measured and pancreatic enzyme monitored. For 7 days patients received total parenteral nutrition and continuous infusion of randomly Somatostatin 14 (S-14) at a dose of 6 mg/24 h (days 1-6) and 3 mg/24 h (day 7) or matching placebo. Pancreatic fistula was defined as a daily drainage of more than 100 cc of amylase-rich fluid after day 3, persisting after day 12 or associated with symptoms or needing specific treatment.
Daily output of pancreatic juice was low during the first postoperative day and then increased gradually until day 5. A high enzyme concentration was observed in pancreatic juice on the first post-operative day. S-14 infusion resulted in a significant decrease of both pancreatic fistula rate and enzyme concentration in peripancreatic fluid.
During the first postoperative days, the outflow of the exocrine secretion of the pancreatic remnant is low but contains a high enzyme concentration with significant leaks within the peripancreatic area. S-14 infusion results in a decrease of pancreatic juice leaks from the pancreatic remnant.

ABSTRACT: To study tolerability and efficacy of an intensified chronomodulated schedule of fluorouracil (5-FU) and l-folinic acid (l-FA) as first-line treatment of metastatic colorectal cancer, 5-FU was given near individually determined dose-limiting toxicity in a multicenter phase II trial.
One hundred patients (68 men and 32 women, median age 62 years, World Health Organization performance status less-than-or-equal 2) with previously untreated and inoperable metastases received chronomodulated daily infusion of 5-FU/l-FA (from 10:00 PM to 10:00 AM with peak at 4:00 AM). 5-FU dose was escalated from 900 to 1,100 mg/m(2)/d with fixed dose of l-FA at 150 mg/m(2)/d for 4 days every 14 days.
5-FU dose escalation was achieved in 66% of the patients. Grade 3 to 4 toxicities mainly consisted of nausea or vomiting (14% of patients and 1.5% of courses), hand-foot syndrome (38% of patients and 8% of courses), mucositis (26% of patients and 4% of courses), and diarrhea (21% of patients and 2.3% of courses). Objective response rate (ORR) was 41% (95% confidence interval, 31.5% to 50.5%). Twenty patients underwent metastases surgery; among these, 12 had a complete resection. Median progression-free survival was 7 months. Median survival was 17 months; 28% of the patients were alive at 2 years and 18.6% at 3 years.
The ORR achieved with intensified chronomodulated delivery of 5-FU/l-FA was nearly twice as high as that earlier obtained by our cooperative group using less intensive 5-FU/FA chronotherapy.

ABSTRACT: Mid-term assessment of laparoscopic adjustable silicon gastric banding (Lap-Band) by a specific score.
One hundred consecutive patients received by mail 12 to 54 months after laparoscopic adjustable gastric banding a questionnaire including the Bariatric Analysis and Reporting Outcome System (BAROS) which is the only specific and validated instrument for measuring the quality of life after bariatric surgery. This score includes five categories of results (failure, fair, good, very good, excellent). It uses three major fields: the quality of life, excess weight loss, and medical comorbidities evaluation.
Seventy three patients answered back with a mean follow up of 24.6 +/- 10 months. Forty six (2/3) had lost more than 50% of their weight excess. Sixty six experienced an improvement of their medical conditions following surgery. Final results were good or excellent for 60 patients (82% of those who answered back). Failure was reported in 7 patients (2 "sweet eaters" and 2 pouch dilatations) which needed a surgical treatment.
This evaluation based on the BAROS confirms its validation in France and the good mid-term results of bariatric surgery based on the Lap-Band.

ABSTRACT: It remains debatable whether somatostatin can prevent pancreatic fistula and other pancreatic stump-related complications following pancreaticoduodenectomy. This study assessed the effects of somatostatin-14 (S-14) on pancreatic remnant exocrine secretion.
This was a double-blind, randomized, placebo-controlled trial in patients undergoing pancreaticoduodenectomy for malignancy. Patients received a continuous infusion of S-14 (n = 38) or placebo (n = 37) for 7 days. Pancreatic juice and peripancreatic drainage fluid was collected and measured, and pancreatic enzymes were monitored daily. Postoperative complications were recorded.
S-14 infusion was associated with a decrease in median daily pancreatic juice and pancreatic amylase output. Amylase concentration and output in the peripancreatic drain fluid were significantly lower after S-14 infusion than in the control group (both P < 0.05). The incidence of clinical pancreatic fistula (two of 38 versus eight of 37; P < 0.05) and total pancreatic stump-related complications (five of 38 versus 12 of 37; P < 0.05) was lower in patients treated with S-14. Duration of hospital stay was shorter after S-14 (18 versus 26 days; P = 0.01).
Although the effect of S-14 on exocrine secretion remains difficult to demonstrate, it did reduce pancreatic juice leakage from the pancreatic remnant.

ABSTRACT: To study the characteristics of randomized trials published by general and digestive French surgeons over the last decade.
An extensive electronic and manual literature search was performed. Trials published as original articles compared two surgical techniques or a surgical procedure with a nonsurgical treatment. The characteristics of the trials and their methodology were assessed. At the same time, a survey was conducted among authors to assess the impact of application of the Huriet-Sérusclat law (ethics related to the protection of individuals subjected to bioclinical research) on the conduct of the trial.
Forty trials (including 22 multicentre trials) were found. Twelve trials (30%) addressed a key-question and twenty (50%) addressed a particular step of the procedure (anastomosis, drainage, etc). Most trials (83%) were published in English language journals. The 18 trials with a good methodological quality mainly had a multicentre design (n = 16). The survey showed that 10 trials were conducted prior to the publication of Huriet-Sérusclat law and that 14 trials were conducted in compliance with this law.
This study revealed the large number of well designed multicentre trials in France. But most trials assessed technical steps of the surgical procedures. Application (without prerequisite) of the Huriet-Sérusclat law could probably explain the rarity and the difficulties of conducting trials comparing two different procedures or a surgical with a medical treatment.

ABSTRACT: Laparoscopic fundoplication is a well-established surgical option for the treatment of gastroesophageal reflux disease. The aim of this study was to assess the surgical outcomes from the patient's point of view by using a validated quality of life instrument.
Fifty patients have been prospectively included. All patients underwent a standardized 270-degree posterior fundoplication. Quality of life was measured by the Gastrointestinal Quality of Life Index (GIQLI), a 36-item-questionnaire. The patients received the questionnaire before surgery, and 3 months and 1 year after surgery.
Preoperative score was 95.6+/-21 points. The score increased significantly (P <0.0005) at 3 months (103.6+/-16) and 1 year (111.4+/-22) after surgery. This improvement concerned the four domains of the questionnaire (symptoms, social functioning, physical status, and emotions). The score in patients at 1 year remained, however, significantly lower than that in healthy persons (126+/-18).
GIQLI is a sensitive tool to assess surgical outcomes after fundoplication. The quality of life after surgery did not reach the level of healthy population, not because of failure of surgery to treat GERD but probably because of functional dyspepsia that was present prior to surgery and did not change after fundoplication.
