Gastric mucosal surface in cirrhosis evaluated by magnifying endoscopy and scanning electronic microscopy.

BACKGROUND AND STUDY AIMS: Gastric mucosa may have several tiny patterns in portal hypertension. In this prospective study, we used magnifying endoscopy and scanning electron microscopy (SEM) to better characterize the morphology of gastric mucosa in patients with cirrhosis, and we evaluated the diagnostic accuracy of magnifying endoscopy. PATIENTS AND METHODS: Videotapes of gastric mucosal patterns from 39 cirrhotic patients and 20 control patients were blindly evaluated by the same observer using magnifying endoscopy (magnification x 25) and conventional endoscopy. SEM was performed in 12 other patients. The basic anatomical entities of the gastric architecture on conventional endoscopy were the gastric area in control patients and the mosaic pattern in patients with cirrhosis. RESULTS: With regard to the prevalence of endoscopic patterns in the antrum, the mosaic pattern was more frequent in cirrhotic patients. In the body, the mosaic pattern, white spots, and red marks were significantly more frequent in cirrhotic patients, whereas gastric areas were more frequent in control patients. Concerning the contributions of the techniques, significantly more gastric areas were identified by magnifying endoscopy than by conventional endoscopy. However, in multivariate analysis, only conventional endoscopy with esophageal varices had significant independent diagnostic accuracy for cirrhosis, and magnifying endoscopy of mucosal signs did not add any significant information. SEM did not improve discrimination between control and cirrhotic patients. CONCLUSIONS: Magnifying endoscopy provides more details of the mucosa, thus improving the delineation of gastric mucosal morphology. However, magnifying endoscopy has little clinical value in cirrhosis since it does not improve on the accuracy of conventional endoscopy for the diagnosis of cirrhosis.

[Treatment of common bile duct lithiasis: first-line endoscopic sphincterotomy and celioscopic cholecystectomy].

The aim of this study was to assess retrograd cholangiogram findings and first-line endoscopic sphincterotomy followed by laparoscopic cholecystectomy for the treatment of main bile duct lithiasis. Clinical, biological and echographic criteria predictive of main bile duct lithiasis were observed in 125 patients (32 men, 93 women, mean age 44.2 years) who underwent retrograde cholangiography. Results suggested lithiasis of the main bile duct in 105 case (87.5%) and were confirmed at endoscopic sphincterotomy in 99. There were no deaths; four complications occurred (3 moderate cases of pancreatitis, 1 cholecystitis). Conversion was required in 11.6%, usually because of difficulties in dissecting. No residual lithiasis was observed. Mean duration of hospitalization was 11.4 days. This sequential treatment scheme for main bile duct lithiasis appears to be effective, minimally invasive and safe.

[Standard means in laparoscopic surgery. The peculiar case of cholecystectomy].

Legal suits against visceral surgeons have increased since the advent of laparoscopic surgery. The duties of physicians have not however changed with the development of laparoscopic techniques. Since the decree promulgated in 1936, physicians have a legal commitment to provide the means required for patient care. This obligation has been recalled in different court judgements and in the new deontology code. In addition, jurisprudence tends more and more towards responsibility without risk. Laparoscopic cholecystectomy is not risk-free. Although morbidity and mortality have not risen with laparoscopic procedures, the types of complications encountered have changed. Reported accidents have become more frequent. The number of suits against surgeons has also increased. Surgeons must therefore be highly prudent and diligent. Precautions concerning personnel management, the choice of material and its upkeep. Special care must be given to the peroperative pneumoperitoneum and the use of monopolar electrocoagulation. A peroperative cholangiogram should be obtained. A careful operative report is very important. The surgeon must be able to justify his competence. Finally, the surgical community should publish more results concerning the rate of complications in order to establish reference material for experts.

[Patient information and obtaining informed consent in laparoscopic surgery].

Since the advent of laparoscopic surgery, the number of suits against surgeons has risen. One of the most frequent complaints is the lack of sufficient information. Physicians in France have a formal obligation to provide information in the contractual legal context established since 1936. This notion has been confirmed in several court cases. The requirement for patient informed consent has been confirmed by several decisions of the Appeals Court and is stated in the code of deontology. The value of classical oral information has been recently questioned in certain court cases. We analyse the current legal situation in France and try to define the content of information required in the case of laparoscopic surgery in addition to the way this information is provided and the means of obtaining informed consent. The information provided must be personalised. The patient must informed that laparoscopy remains a surgical operation. It is licit to warn the patient of predictable risks according to statistical probabilities, of the team's experience and of the patients own status including past history and psychological factors. A written statement may be prepared but must remain a document complementary to personalised oral information. The surgeon must obtain and assure good patient comprehension. The surgical community should publish risk rates in order for surgeons to have reliable references which can be used to define the notion of exceptional risk.

[Mega-esophagus: treatment by celioscopic approach].

Heller's procedure is widely used as the most appropriate method for treating achalasia. We performed the procedure laparoscopically in three patients with good results. Two females and one male, age 40, 60 and 68 years, presented with long-term recurrent dysphagia due to achalasia which did not respond to endoscopic dilatation. Heller's procedure was performed laparoscopically in all three with no particular difficulty. In our cases we also attached the anterior border of the greater curvature to the left side of the myotomy and fixed it to the right diaphragmatic pillar to reduce reflux. The procedure would appear to have less risks than laparotomy since visualization of the operative fields is better. Laparoscopy will undoubtedly become the preferred procedure for achalasia.

[Cancer of the gallbladder. A surgical experience. A propos of 143 cases].

The records of 143 patients with gallbladder carcinoma operatively treated between 1975 and 1995 were retrospectively reviewed. Abdominal pain was the most common symptom and was present in 103 patients (72%). Jaundice was present in 83 patients (58%) and weight loss in 68 (47.5%). Pre-operative diagnosis was made in 40.5% of the patients. Surgical procedures included cholecystectomy alone (16.8%), cholecystectomy with resection of the hepatic bed and lymphadenectomy (11%), cholecystectomy with biliary drainage (57.3%), and exploration with biopsy (14%). Surgery was considered as curative in 21.5% of the patients. Overall five-year survival rate was 11%. Actuarial 5-year survival rate was 100%, 29% and 23% in patients with T1, T2 and T3 tumors. The five-year survival rate was nil in patients with T4 and T5 cancers.

[Palliative treatment of rectal cancer by the trans-anal approach using a urologic prostatectomy device].

Palliative treatment for patients with rectal carcinoma affect more than 10% of the 8000 cases diagnosed each year in France. Twenty-four patients underwent endoscopic trans-anal resection using a urological resectoscope. The morbidity rate was 18,5% and there were no postoperative deaths. The median hospital stay for the procedure alone was 4 days. Good palliation was obtained in 89% of cases. This simple, minimally invasive and economic method should join palliative treatment for patients with rectal carcinoma beside laser destruction and external beam radiotherapy.

[Mucinous ductal ectasia. Apropos of 2 cases].

Mucinous ectasia of the pancreas ducts is a recently described cystic lesion which usually occurs in acute pancreatitis. Endoscopic retrograde pancreatography provides diagnosis. Mucinous ductal ectasia is considered to be a precancerous lesion. Surgical exeresis is recommended. Our two cases emphasize the difficulties encountered for differential diagnosis with other cystic lesions of the pancreas.

Laparoscopic continent gastrostomy.

Surgical feeding gastrostomy is attended by a significant morbidity and mortality. The percutaneous endoscopic route is regarded as the best method, but it is not feasible in cases with pharyngoesophageal stenosis. We here describe a new method using laparoscopy. The technique is easy to perform. The patient retains continence, with the abdominal wall muscle acting as a sphincteric mechanism around the gastric tube.

Pancreatoduodenectomy for hemosuccus pancreaticus in silent chronic pancreatitis.

Hemorrhage is an infrequent but known complication of chronic pancreatitis. The pathogenesis of spontaneous bleeding includes splenic vein thrombosis, pancreatic lithiasis, and erosion of a pseudocyst into vessels incorporated in its wall. Bleeding may occur into the gastrointestinal tract, the peritoneal cavity, or retroperitoneum. Moreover, bleeding can be severe, with rapid development of shock, or mild in patients who have exhibited minimal clinical symptoms. "Hemosuccus pancreaticus" is the term coined to describe the rare case of bleeding observed to occur through the ampulla of Vater. Exceedingly rare, as was the case in our patient, is when hemosuccus pancreaticus is due to a bleeding pseudocyst of the head of the pancreas in the absence of gastrointestinal blood loss as well as abdominal pain.

[Intraoperative colonic irrigation in the emergency treatment of occlusive lesions of the left colon].

This study reports the use of an intraoperative antegrade colonic irrigation in the management of left-sided large bowel obstruction requiring emergency surgery. 35 consecutive patients had primary bowel resection with immediate anastomosis (without colostomy) after intraoperative antegrade colonic irrigation. The cause of the obstruction was large bowel carcinoma in 26, diverticulitis in seven and volvulus in two cases. There were two post-operative deaths (5.7%). No digestive fistula was observed. The results of this study suggest that intraoperative colonic irrigation is an effective method, enabling the surgeon to perform a primary anastomosis with reasonable safety after emergency resection of selected distal colonic lesions.

[Correction of substance losses in the abdominal wall by an aponeurotic graft].

A series of 123 patients presenting with abdominal eventrations were treated by an aponeurotic graft. Operative mortality was 0.8%. Recurrent eventration was observed in eventrations with a diameter superior to 4 cm (38% at 55 months). The authors recommended this technique only in case of small eventrations or for the parietal reparation following closure colostomies.

[Mesocaval anastomosis in the treatment of recurring hemorrhage caused by portal hypertension].

The ideal therapy for variceal hemorrhage would permanently eliminate this life-threatening complication of portal hypertension and have no adverse effects on hepatic physiology. Mesocaval interposition shunts preserve a hepato-pedal blood flow. 35 shunts were performed as an elective procedure from 1982 to 1992 in patients with hemorrhagic liver cirrhosis. There were 24 men and 11 women, with a median age of 51.7 years. The underlying etiology of the varices was alcoholic cirrhosis in 31 patients. The criteria of Child-Pugh were utilised to evaluate + all patients; 21 were in class A and 14 were in class B. All patients presented before the operation, two or several histories of acute variceal hemorrhage. The mean diameter of the graft was 14 mm (range 10 to 16 mm). Intra-operative portal pressure measurements showed satisfactory pressure reduction (18.7 mmHg to 11.2 mmHg). There was no death in the postoperative period. Eight patients had postoperative complications, for an overall morbidity rate of 22.8%: 2 ascites, 4 episodes of temporary encephalopathies and 2 recurrent bleeding. At the third month, angiographic (5 cases), sonographic (6 cases) or scanographic (17 cases) studies evaluated shunt patency. In one case, We observed an occluded graft. The actuarial survival rate was 82% at 2 years, 66% at 5 years. It is concluded that the interposition mesocaval shunt appears to be an effective technique for the control of variceal hemorrhage, has important hemodynamic advantages and can be applied to most patients for the control of variceal hemorrhage due to portal hypertension. Moreover, the procedure can be considered as a solution before the hepatic transplantation.
