Hematemesis from esophageal varices associated with esophageal perforation: sclerotherapy and endoscopic clipping.

A 46-year-old man was referred to our Unit for hematemesis. The medical history of the patient revealed an HCV-related cirrhosis, a human immunodeficiency virus (HIV) infection and recent and persistent episodes of emesis. An urgent gastroscopy disclosed evidence of active bleeding from varices of the lower third of the esophagus and a concomitant laceration of the esophageal wall due to the emesis. These two conditions have been endoscopically diagnosed and successfully treated by sclerotherapy and endoscopic clipping.

[Use of expandable metal stents for gastroduodenal outlet obstruction]. / Uso degli stent metallici espansibili nelle ostruzioni maligne gastroduodenali.

Gastroduodenal obstruction is a preterminal event in patients with advanced malignancies of the stomach, pancreas and duodenum. Surgical gastrojejunostomy has been considered the traditional palliative treatment. The use of metallic stents is intended not to be curative but to provide nonsurgical palliation for the symptoms of obstruction. The advantages of this technique are the minor invasivity, the decrease in morbidity and mortality respect the surgical approach, the patient that can be discharged the day of or the day after the procedure and the better life expectation.

[Distal hyperplastic polyps as a marker for advanced neoplasm of the proximal colon. Our experience]. / Il polipo iperplastico distale come marcatore di neoplasia colica avanzata prossimale. La nostra esperienza.

BACKGROUND AND AIM: While, several studies indicate that there is an association between proximal and distal colorectal adenomas, no agreement seems to be between the presence of distal hyperplastic polyps and proximal neoplasia. The aim of this study was to investigate, retrospectively, the possible correlation between the distal hyperplastic polyps and proximal colorectal neoplasia. MATERIALS AND METHODS: In our GI Unit, from 1st February 2006 to 24 November 2006, we performed 142 polypectomy. Patients were 36 females and 80 males, with a median age of 66 years [range: 38-87 years]. All of the polpys were resected during colonoscopy and sent for histological study. Chi-square test was used for statistical analysis. A probability value of P< or =0.05 was considered to be statistically significant. RESULTS: Histological study showed the following results: 33 hyperplastic polyps (8 F, 21 M; median age 63 years), 100 adenomas (26 F, 61 M; median age 67 years) and 2 inflammatory polpys (2 F, 0 M; median age 71 years). The rectal localization was associated with a significantly higher frequency of hyperplastic polyps (63.6% vs 23.5%), OR: 5.688 (95% C.I. 2.445-13.230) (p<0.0001). Five hyperplastic polyps of the rectum were associated with 5 adenomas located 1 in the rectum, 2 in the sigmoid colon, and 1 in the descendens colon and 1 in the ascendens colon. While, 5 adenomas were associated with 5 adenocarcinoma. CONCLUSIONS: Guidelines from the American College of Gastroenterology and the American Society of Gastrointestinal Endoscopy do not recommend colonoscopy for patients with distal hyperplastic polyps. Also our study is in keeping with the data of the literature and it confirmed that rectal localization is associated with a higher prevalence of hyperplastic polyps.

[Foreign bodies in the upper gastrointestinal tract. Personal experience]. / Corpi estranei del tratto digestivo superiore. Esperienza personale.

OBJECTIVE: Foreign bodies ingestion is a potentially serious problem. The majority of ingested foreign bodies pass spontaneously, but serious complications, such as bowel perforation and obstruction, can occur. In the present work, we report our experience in the management of ingested foreign bodies. MATERIALS AND METHODS: The study was observational and retrospective. We included in the study the foreign bodies ingestions occurred during urgent endoscopy (examination performed from 1 to 6 h by the call). RESULTS: Records of 696 consecutive EGDS performed in urgency at the Unit of Gastroenterology and Digestive Endoscopy of the Hospital Sandro Pertini of Rome, from 01-02-'04 to 18-01-2006, were analyzed retrospectively. Out of these procedures, 21 (3.01%) were performed for suspected foreign bodies ingestion. CONCLUSIONS: We present the initial report of our working experience. Objects that have passed the duodenum should be managed conservatively by radiographic surveillance and inspection of stool. Endoscopic or surgical approach is indicated when significant symptoms develop or if the object fails to progress through the gastrointestinal tract. The present data are in keeping with previous studies of the literature.

Placement of two overlapping uncovered metallic stents for malignant gastric outlet and duodenal obstruction due to colon cancer.

Malignant obstruction of the gastric outlet and duodenum is frequently due to extrinsic involvement by tumors from contiguous organs, in particular from pancreas and gallbladder. The treatment of malignant gastroduodenal stenoses is difficult. Many patients have advanced malignant disease and are too ill to undergo surgical approach. Surgical gastrojejunostomy has been considered the palliative treatment of choice. Metallic stents can be useful in this condition with adequate palliation obtained in most cases. We report a case in which self-expanding metallic stents were placed for stenoses of the gastric outlet and duodenum due to a colon cancer.

Large aneurysm of the superior mesenteric artery.

This report describes a rare case involving a large aneurysm of the superior mesenteric artery (S.M.A.) in a 53-year-old female. Diagnosis was made by X-ray and echography and confirmed by CT-scan and arteriography showing the lesion to be atherosclerotic in origin with several thrombi on the wall of the artery. Resection of the aneurysm and venous reconstruction was performed. Recovery was uneventful. Angiography one month later demonstrated patency of the bypass. At six months the patient is presently asymptomatic.

[Supplemental proposal in the surgical treatment of liver injury. Experimental studies]. / Proposta complementare nel trattamento chirurgico della trancia epatica. Ricerche sperimentali.

Liver resections pose a great variety of problems, not least repair of the cut. The various reconstruction modalities are reviewed and personal experience in twenty rats submitted to surgical removal of the median lobe of the liver with cover of the sectioned surface by means of omental mesh autograft is reported. The results were flattering for the absence of significant complications and for the haematological and haematochemical data obtained which confirm low easily the graft takes, its regenerative potential and the modulator action of peritoneal repair processes.

[Surgical proposals concerning omental mesh graft. Experimental studies]. / Proposizioni chirurgiche dell'innesto omentale a rete. Ricerche sperimentali.

In general surgery, the advantages deriving from the utilisation of omental graft are attributable to the ease with which it takes, its regenerating potential and the modulator action on tissue repair. Personal experience regarding the peritoneization and covering of surgical liver surfaces is reported and the use in various sectors of surgery of omental mesh graft is recommended.

[Endoscopic sphincterotomy in acute biliary pancreatitis. A multicenter study]. / La sfinterotomia endoscopica nella pancreatite acuta biliare. Studio multicentrico.

BACKGROUND: Severe acute pancreatitis are still dangerous, as can be seen from the high mortality rate (around 30%). It's commonly known that in the last years diagnostic ability, precise stadiation and control over the disease development were increased. Surgical therapy is directed mainly to achieve the control over septic evolution, and in biliary pancreatitis to resolve hypertension and infection inside the biliary tree (now widely accepted as the real cause of this disease). Recently, some authors demonstrated that the prognosis of a pancreatitis can be greatly improved by stopping the evolution toward a severe phase with necrosis and multiple organ failure without any surgical operation. They believe that's possible to achieve this result performing an early endoscopic sphincterotomy in all biliary pancreatitis (recognised by means of echography and CT scan), before the development of necrosis. METHODS: In our department, following this address, very good results have been obtained: that's why a multicentric trial has been carried out to appraise the results obtained by endoscopic sphincterotomy within 48 hours from the disease onset. Answers from 114 hospitals were received, with a total survey of more than 10,000 pancreatitis. Endoscopic sphincterotomy was performed in 55% of billiary pancreatitis, which were estimated at the onset, on second or third degree of Balthazar classification. RESULTS: In 86% of patients, endoscopic sphincterotomy was performed within 48 hours from symptoms onset. Complications related to this treatment are reported in less than 4% of patients. CONCLUSIONS: The procedure, avoiding the evolution toward necrosis and sepsis, allowed the reduction of surgical operations to 6.7%, and of the mortality amongst all cases gathered to 2.5%.

[Endoscopic treatment combined with adrenaline injection and coagulation with argon plasma in gastroduodenal peptic ulcer bleeding]. / Trattamento endoscopico combinato iniezione di adrenalina e coagulazione con Plasma di Argon (APC) del sanguinamento da ulcera peptica gastro-duodenale.

Although endoscopic injection therapy is an effective method for bleeding peptic ulcers, it is associated with significant re-bleeding rate; whether the addition of thermal method improves the outcome is still unclear. Our previous experience showed that Argon Plasma Coagulation (APC) alone is not sufficient in stopping spurting haemorrhage, and potentially dangerous for large non bleeding visible vessels (NBVV). Our hypothesis was that combination of adrenaline injection (AI) and thermal therapy could be more efficient than thermal therapy alone for permanent haemostasis of active bleeding peptic ulcers, and particularly appropriate for NBVV treatment. From October 1998 to February 2000 we examined two hundred patients with upper gastrointestinal bleeding. Fifty-three patients with major peptic ulcer haemorrhages received combined injection therapy with adrenaline 1:10.000 and Argon plasma coagulation; there were 34 male and 19 female with a mean age of 63.2 +/- 1.2 years (range 22-93). The bleeding site was duodenal in 30 patients, gastric in 17 patients, anastomotic in 5 patients and esophageal in 1 patient. Endoscopic findings were the following: active bleeding in 23 patients (6 spurting, 17 oozing), non bleeding visible vessels in 12 patients and fresh adherent clots in 18 patients. Initial haemostasis was achieved in 52/53 patients (98.1%). Re-bleeding was observed in 5/52 cases (9.6%). Surgery was necessary in 3/53 patients (5.6%). Mortality was 7.5% (4 cases). No major complications resulted from this treatment. Primary adrenaline injection provided initial bleeding arrest, facilitating the following application of APC, because of a more precise definition of the active bleeding site. Rates of initial hemostasis were significantly higher with combined therapy (injection + APC) compared to APC treatment alone. We believe that Adrenaline and APC combined therapy is an effective and safe method for treatment of non-variceal gastrointestinal bleeding.

[Endoscopic sphincterotomy in acute biliary pancreatitis: the complications]. / La sfinterotomia endoscopica nella pancreatite acuta biliare: complicanze.

The authors report on a multicentric trial performed on early endoscopic sphincterotomy in severe pancreatitis. A large figure (7.764) of biliary pancreatitis was collected and 4.285 sphincterotomies were carried out. The results have been highly satisfactory: removal of hypertension and infection in biliary tree, stopped the trend toward necrosis and infection in almost all cases precociously treated. However, answering to the many doubts raised by some colleagues about the danger of this method, the authors examined all the complications that were reported. Hemorrhages and perforations of the biliary tree were the most common one. There were 120 (2.8%) hemorrhages, most frequently treated by medical means; in 20 cases a surgical hemostasis (1 death) had to be performed. Perforations, 24 (0.56%) were treated by medical therapy in 18 cases; 6 patients underwent surgical approach, with no deaths. Other complications (cholangitis, stent ruptures), less frequent, were treated successfully without surgical operations. The authors believe the main cause of this complications to be lack of experience and delay of endoscopic procedure (papillary oedema, fragility). What they suggest, is that endoscopic sphincterotomy has to be performed by an expert endoscopist, and within 48-72 hours from disease onset. Observing also that contrast introduced in the biliary tree could be harmful, they suggest to practice cholangiography at low pressure, and always leaving a nose-biliary drain. Endoscopic sphincterotomy, therefore, if correctly performed, reduces the necessity of surgery in severe pancreatitis. In this way, operations have to be carried out only in those patients with septic complications, with encouraging results and a sharp reduction of mortality.

[Peritoneal oxygenation-dialysis as a temporary treatment of intestinal infarction]. / L'ossigenazione-dialisi per via peritoneale come trattamento provvisorio dell'infarto dell'intestino.

The interval preceding the growth of irreversible lesions in an abdominal apoplexy is variable (3-48 hours). It may be used to improve the ischaemic viscus oxygenation, also compensating possible metabolic imbalances. 16 rabbits were used for research, in which apoplexy by the ligature of the arteria mesenterica superior was induced. Dialysis-oxygenation peritoneal treatment was carried out for 8 rabbits, the results of which were evaluated on the basis of the intestine macroscopic morphologic aspect; on the basis of the hematic phosphates values and in enteral biopsy. The oxygenation-dialysis produced a rapid improvement in enteral hue and in enteral motility, an important increase of PO2 and a reduction of hematic phosphates compared with the control group. Histologic examination did not show any significant variation. The attempt to increase general oxygenation by supplying PO2 via the peritoneum, was partly successful (10-15%). The aim of oxygenation the ischaemic enteral zone was successful. This due to elimination of CO2 and toxic products using dialysis. This simple method seems to be effective but further tests on swine would be necessary for clinical applications.

[Diverticula of the cecum. Our experience]. / I diverticoli del cieco. La nostra esperienza.

On the basis of their experience in right colonic emergencies, the Authors report two cases of diverticular disease presenting with acute abdomen. Pointing out the difficulty of a correct pre- and intraoperative diagnosis, different surgical procedures are analysed.

[Difficult endoscopic extraction: pneumomediastinum and bilateral pneumothorax after attempted endoscopic extraction of needle incarcerated in hiatal hernia]. / Estrazione endoscopica difficile: pneumomediastino e pneumotorace bilaterale dopo tentativo di estrazione endoscopica di un ago da rammendo incarceratosi in una ernia iatale.

From June 1987 to April 2000, 167 (74%) of 223 patients suspected of swallowing foreign bodies were treated. Hundred-sixty-three were successfully treated endoscopically. The surgery rate was 2.4%. There was failure to remove a tablespoon, a tooth-brush, a dental prostheses with metallic hook, a knitting-needle. The sharp and pointed foreign bodies were 35 (20.9%). Endoscopic removal of sharp and pointed foreign bodies in the upper gastrointestinal tract can be very difficult to manage. The Authors report iatrogenic perforation of esophagus-gastric-fundus in a patient with hiatus hernia who ingested a big knitting-needle in order to suicide. They think that it is absolutely necessary to use special endoscopic equipment during the taking out of foreign-body procedure, especially when pointed and sharp-edge shaped bodies are involved and when there is high risk of iatrogenic lesions.

Role of endoscopic sphincterotomy of the minor papilla in pancreas divisum.

BACKGROUND: Pancreas divisum (PD) is a common anatomical variant of the pancreatic duct system. Only a little percentage of patients with this altered anatomy develop symptoms: acute recurrent pancreatitis (ARP), chronic pancreatitis (CP) and pancreatic-type pain alone. These have been supposed to arise from an obstruction to outflow of the pancreatic dorsal duct due to a stenosis of the minor papilla. Endoscopic sphincterotomy of the minor papilla (MiES) can be considered an effective treatment for patients with PD and ARP supported by stenosis or obstruction of the minor papilla. On the other hand, the access through the minor papilla is essential for therapeutic pancreatic endoscopy in patients with PD and CP, but the effectiveness of MiES in these patients is extremely controversial. MATERIALS AND METHODS: Aim of this brief review has been to evaluate the short and long-term effects of endoscopic pancreatic interventions in patients affected by symptomatic PD who underwent therapeutic endoscopic retrograde cholangiopancreatography (ERCP) with pancreatic sphincterotomy of the minor papilla (MiES). The main literature database was Medline (1966-2013). RESULTS: Data come from a personal overview of articles emerging from the same search strategy. CONCLUSIONS: Nowadays, when endoscopic pancreatic drainage is indicated in patient with symptomatic PD, access through the minor papilla (MiP) is required. Therapeutic endoscopic interventions provide less invasive alternatives to the surgical approach.

Efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) performed in patients with Periampullary duodenal diverticula (PAD).

BACKGROUND AND AIM: Periampullary diverticula (PAD) are found in 9-32% of patients who undergo endoscopic retrograde cholangiopancreatography (ERCP). PAD are acquired lesions which are rare in patients <40 years, but increasing with age. Several endoscopic studies have revealed an association between PAD and common bile duct (CBD) stones. The presence of a papilla located in the diverticula is also frequent (6.8-54.9%) and represents a restrictive factor for successful cannulation. MATERIALS AND METHODS: A retrospective analysis has been made of data related to the patients with PAD treated at our GI Unit (small center with low case volume), who underwent ERCP in the period 1st January 2010 to 31st March 2014. For each patient were analyzed data regarding sex, age at diagnosis, indication to ERCP, cannulation rate, endoscopic treatment and complications. PAD were classified in 3 different types according to the position of the major papilla. RESULTS: A total of 647 ERCPs have been performed of which 77 (16.5%) in pts with PAD (48 F, 29 M, mean age: 78.3 years; range: 48-95). PAD type I (inside the diverticulum) were found in 22 pts (28.6 %), Type II (in the margin of the diverticulum or between two PADs) in 36 pts (46.7 %) of which 12 cases between two PADs, type III (near the diverticulm) in 19 pts (24.7 %). The indication for ERCP were: 72 CBD stones (93.5%), 3 cholangiocarcinoma (3.9%) and 2 pancreatic head cancer (2.6%). In cases of difficult cannulation, precut was performed in 12 pts (15.6%). Deep CBD cannulation and endoscopic sphincterotomy (ES) was achieved in 70 cases (90.9%). The other 7 case of failure were all in patients with CBD stones. Complete clearance of CBD stones was achieved in 57 patients (87.7%) (57/65 ERCP/ES). Stent placement was necessary in 8 cases (12.3%) (8/65 ERCP/ES), due to multiple large stones. The adverse events related to ERCP/ES included 4 intraprocedural bleeding (5.7%) (4/70 ERCP/ES) and 1 mild pancreatitis (1.4%) (1/70 ERCP/ES), all managed conservatively. CONCLUSIONS: Our data show that ERCP is a safe procedure also in patients with PAD, with a good success rate and low complications.

Quality of life in ulcerative colitis patients treated medically versus patients undergoing surgery.

OBJECTIVES: Approximately one third of patients with ulcerative colitis (UC) require surgery. AIM: Aim of this study was to assess the quality of life (QoL) of UC patients who have undergone surgery with ileorectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA) compared to UC patients not operated. PATIENTS AND METHODS: Fifty consecutive UC patients for each group observed between 1988-2010 were included. To all patients was administered a self completed questionnaire with four different scores: intestinal symptoms (IS), systemic symptoms (SS), emotional function (EF), social function (SF) and an overall QoL score. RESULTS: Overall QoL score and three dimensions (SS, EF, SF) resulted not significantly different in the three groups, except for IS that resulted worst in the IRA-Group. According to the activity of disease it appeared that UC and IRA patients with mild activity had an overall QoL score similar to patients with complicated IPAA. A higher statistically different score of overall QoL was observed in patients with UC and IRA with moderate/severe disease. CONCLUSIONS: Results of the study demonstrate that overall QoL score is poorer in patients with UC and IRA with mild activity and in patients with complicated IPAA and is worst in patients with UC and IRA with moderate/severe activity.

Comparison of endoscopic retrograde cholangiopancreatography between elderly and younger patients for common bile duct stones.

BACKGROUND: Choledocholithiasis is increasing in elderly subjects. The introduction of endoscopic retrograde cholangiopancreatography with biliary sphincterotomy has almost replaced surgery in the treatment of this condition. The aim of the present study was to evaluate the rates of successful clearance of common bile duct stones and the endoscopic techniques used in a population aged 75 years or older compared with those in a younger age group. MATERIALS AND METHODS: A retrospective analysis was made of data related patients who underwent endoscopic retrograde cholangiopancreatography for choledocolithiasis in the period 2010-2011. For all patients, factors such as sex, age at diagnosis, endoscopic treatment (stone extraction using baskets and balloon, mechanical lithotripsy and balloon dilatation of the ampulla, placement of a stent or a naso-biliary tube) and need of surgery were analysed. Two groups of patients were identified: patients aged <75 years (Group A) and patients aged ≥75 years (Group B). For the statistical analysis Mann-Whitney test and Fischer's Exact test were used. RESULTS: A total of 234 patients were enrolled in the study (94 in Group A, 140 in Group B). No statistically significant differences were observed as far concerns sex, previous cholecystectomy, gallbladder stones and periampullary diverticula, but only for common bile duct dilatation. Complete clearance of common bile duct stones was achieved in 230 patients (97.5%). CONCLUSIONS: The present data are in keeping with those presented in the literature, which confirm that endoscopic retrograde cholangiopancreatography is a safe and effective procedure also in older patients.

Gastric Dieulafoy's lesion successfully treated by "adjuvant" arterial embolization and endoscopic clipping.

While it is well recognized that peptic ulcer disease is the most common cause of nonvariceal upper gastrointestinal bleeding, other lesions cause of haemorrhage, even if rare, may potentially life-threatening. These include arteriovenous malformations such as Dieulafoy's lesion, defined as caliber-persistent submucosal vessel. The endoscopy with its hemostatic techniques is usually the treatment of choice for such patients. In those cases, in which these techniques fail due to the difficult in the correct localization, angiography with embolization may be a good alternative. The use of microcatheters and new embolic agents have improved this procedure. In fact, transcatheter arterial embolization represents a minimally invasive alternative to surgery when endoscopic treatment fails to control gastrointestinal bleeding, especially for the upper tract. This technique proved to be safe, fast and effective. According to our knowledge, only one case of a Dieulafoy's lesion of the duodenum treated with "adjuvant" embolization followed by laser coagulation has been reported in literature. Herein, we report a case of a Dieulafoy's lesion of the stomach, in which "adjuvant" transcatheter arterial embolization has permitted a more easier endoscopic diagnosis and treatment.

Self-expandable metal stent placement for treatment of severe sphincterotomy bleeding.

One of the most frequent complications of endoscopic sphincterotomy (ES) is bleeding. When post-ES bleeding does not respond to the use of typical endoscopic therapy, the only alternative is angiography or surgery. A 82-year-old female was admitted for jaundice. A RMN-cholangiography revealed multiple stones in the common bile duct (CBD). She underwent endoscopic retrograde cholangiopancreatography (ERCP). The papilla major was located between two large periampullary diverticula. During the ES, a severe bleeding was observed from the upper part of the biliary cut. Several methods of hemostasis (injection of adrenaline, thermal methods and balloon tamponate) were performed without efficacy. A partially covered metallic stent was placed across the biliary orifice, in order to compress mechanically the bleeding site archiving the hemostasis.
