Endolaparoscopic rendezvous treatment: a satisfying therapeutic choice for cholecystocholedocolithiasis.

BACKGROUND: There are many different strategies for the treatment of the main bile duct lithiasis. When lithiasis of the biliary tract is suspected at a preoperative stage, we can treat patients with sequential treatment: endoscopic netrograde cholangiopancreatography followed by laparoscopic cholecystectomy. If common bile duct-lithiasis is recognized at an intraoperative stage, many options for treatment exist, one of which is intraoperative retrograde endoscopic sphincterotomy (ES) (laparoendorendezvous). METHODS: We report our experience using the aforementioned technique with 58 patients affected by cholelithiasis and complex Common bile duct disease who underwent laparoscopic cholecystectomy and intraoperative ES consecutively from March 1996 to May 2000. Of the 58 patients, 43 were affected by cholecystocholedocolithiasis: 12 by previously described lithiasis plus stenosant papillitis, 2 also by a pancreas head cancer, and 1 by cancer of the papilla. RESULTS: The combined technique was performed in 86% of the cases. Six patients required conversion to open surgery. In two other patients, laparoscopic choledocotomy was performed with positioning of a Kehr-tube for an ampulla-impacted lithiasis. CONCLUSIONS: Intraoperative ES offers a valid approach to the treatment of cholecystocholedocolithiasis in one session. Furthermore, it represents a valid alternative to transcholedocical laparoscopic treatment of cholelithiasis and complex common bite duct pathology.

Digestive hemorrhages of obscure origin.

BACKGROUND: The diagnosis of digestive bleeding in some cases can require a diagnostic laparotomy when other methods have been ineffective. Video-laparoscopy can provide such cases with a certain diagnosis and the possibility of performing a simultaneous surgical treatment. METHODS: Our experience using video-laparoscopic to treat digestive hemorrhages of obscure origin involved 16 patients. The examined patients presented with the following diseases: Meckel's diverticulum (8 cases), gastric leiomyoma (1 case), small bowel leiomyoma (4 cases), jejunum leiomyosarcoma (1 case), small bowel melanoma (1 case), and Peutz-Jeghers syndrome (1 case). RESULTS: In all these patients the laparoscopic approach allowed us to identify the origin and site of the hemorrhages, and subsequently to treat the identified lesions. In one patient, an intraperitoneal resection of the diverticulum was performed using Endo-Gia (TM30NIF; Tyco Auto-Suture). In the remaining cases, a minilaparatomy was performed for resection of the disordered loop. CONCLUSIONS: Video-laparoscopy is very useful for avoiding explorative laparatomies on patients affected by digestive hemorrhages of obscure origin. In these cases, the video-laparoscopic approach allows full and meticulous explorations of the small bowel to be performed, and seems to be useful for diagnosis through direct observation of the lesions. Moreover, if necessary, video-laparoscopy can be used for the effective treatment of the diseases.

Squamous papilloma of the esophagus: long-term follow up.

BACKGROUND AND AIM: Squamous papilloma of the esophagus is a rare benign tumor; less than 200 cases have been reported in the literature. The prevalence of endoscopically diagnosed squamous papilloma of the esophagus has been reported in only a very few series, and varies from 0.01 to 0.43%. Clinical relevance and possible association with other pathological conditions, namely if it is a premalignant lesion, remain a matter of debate. The etiology is controversial, although a role of human papilloma virus has been recently proposed. The aim of this study was to try to determine the prevalence, clinical relevance, possible association with other pathological conditions of the upper digestive tract, and possible etiological role of human papilloma virus on our series of squamous esophageal papillomas. METHODS: Data from a total of 7618 upper gastrointestinal endoscopies consecutively performed in 4 years were obtained. A 4-year follow up was carried out. RESULTS: Squamous esophageal papilloma was found in nine patients (0.01%). The mean size of polyps was 4 mm and the mean distance from the dental ridge was 25 cm. Only one patient had more than one polyp. Two patients had liver cirrhosis and three had peptic ulcer disease. All squamous esophageal papillomas were removed and tested for human papilloma virus with commercial available kits for in situ hybridization, but none was found positive. CONCLUSION: Squamous papilloma of the esophagus is an uncommon disease that does not appear to predispose to esophageal cancer. No association was found with human papilloma virus.

Endoscopic management of foreign bodies in the upper gastrointestinal tract: report on a series of 414 adult patients.

BACKGROUND AND STUDY AIMS: Ingestion of foreign bodies is a common occurrence. Few papers in the literature report experience and outcome at tertiary centers. The aim of this paper is to report the management and the outcomes in 414 patients admitted for suspected ingestion of foreign body between May 1995 and December 1999. METHODS: A plain radiographic film of the neck, chest or abdomen was obtained in the case of radiopaque objects, and in order to rule out suspected perforation: in such cases a computed tomography (CT) study was also performed. All patients were asked to give their informed consent, which was refused by three patients. Anesthesia was always used, either conscious sedation (86.8 %), or general anesthesia in the case of poor patient tolerance (13.2 %). All patients underwent an endoscopic procedure within six hours of admission. A flexible scope was used in all patients and a wide range of endoscopic devices was employed. RESULTS: Foreign bodies were found in 64.5 % of our patients. Almost all were found in the esophagus. The types of foreign body were very different, but they were chiefly food boluses, bones or cartilages, dental prostheses or fish bones. In three patients (1.1 %) it was impossible to endoscopically remove the foreign body, which was located in the cervical esophagus: all these three patients required surgery. No complications relating to the endoscopic procedure were observed, but 30.7 % of patients had an underlying esophageal disease, such as a stricture. Only eight patients required a second endoscopic procedure, performed by a more experienced endoscopist. CONCLUSION: Foreign body ingestion represents a frequent reason for emergency endoscopy. The endoscopic procedure is a successful technique which allows the removal of the foreign bodies in almost all cases without significant complications. Surgery is rarely required.

[Central segmental pancreatectomy in benign and borderline neoplasms of the pancreatic isthmus and body]. / La pancreasectomia segmentaria centrale nelle neoplasie benigne e borderline dell'istmo e del corpo del pancreas.

We report our experience with middle segment pancreatectomy for benign, cystic and borderline tumours of the neck and body of the pancreas. The guidelines for management of these tumours are unclear. Formerly they were usually resected with a pancreatico-duodenectomy or distal pancreatectomy including the spleen. However, such operations may cause high morbidity, a notable wastage of normal tissue and an unnecessary risk of diabetes mellitus and splenic loss. Four patients (age range: 34-72 years) with tumours of the neck or body of the pancreas underwent a middle segmental pancreatectomy. The cephalic stump was sutured with duct ligation. The distal stump was anastomosed with a Roux-en-Y jejunal loop. Neither pancreatic fistulas nor operative death occurred in any of the patients. In 3 patients with serous cystadenoma and in one with mucinous cystadenoma, the tumours measured 3.5 to 7 cm in size. These were located in the neck and body of the pancreas and could not be safely enucleated without compromising the pancreatic duct. All tumours were resected with clear margins. The mean operative time was 230 minutes and the median postoperative hospital stay 14 days (range: 10-23 days). The patients have been followed up for five years after surgery and all are disease-free. None of the patients became diabetic or presented exocrine insufficiency. Middle segment pancreatectomy may be an appropriate technique for selected benign or borderline pancreatic tumours in the neck and body of the pancreas. This procedure has an acceptable surgical risk when compared to that of major pancreatic resections and preserves pancreatic function and the spleen.

Autistic savants. [correction of artistic].

OBJECTIVE: The objectives of this study were to examine common patterns in the lives and artwork of five artistic savants previously described and to report on the clinical, neuropsychological, and neuroimaging findings from one newly diagnosed artistic savant. BACKGROUND: The artistic savant syndrome has been recognized for centuries, although its neuroanatomic basis remains a mystery. METHODS: The cardinal features, strengths, and weaknesses of the work of these six savants were analyzed and compared with those of children with autism in whom artistic talent was absent. An anatomic substrate for these behaviors was considered in the context of newly emerging theories related to paradoxical functional facilitation, visual thinking, and multiple intelligences. RESULTS: The artists had features of "pervasive developmental disorder," including impairment in social interaction and communication as well as restricted repetitive and stereotyped patterns of behavior, interest, and activities. All six demonstrated a strong preference for a single art medium and showed a restricted variation in artistic themes. None understood art theory. Some autistic features contributed to their success, including attention to visual detail, a tendency toward ritualistic compulsive repetition, the ability to focus on one topic at the expense of other interests, and intact memory and visuospatial skills. CONCLUSIONS: The artistic savant syndrome remains rare and mysterious in origin. Savants exhibit extraordinary visual talents along with profound linguistic and social impairment. The intense focus on and ability to remember visual detail contributes to the artistic product of the savant. The anatomic substrate for the savant syndrome may involve loss of function in the left temporal lobe with enhanced function of the posterior neocortex.

[Primary ano-rectal melanoma]. / Il melanoma primitivo ano-rettale.

Primary malignant anorectal melanoma is an uncommon disease that accounts for 1% of anorectal malignancies. Its virulent malignancy is associated with a poor prognosis and with difficult diagnostic and therapeutic problems. The operative management of these patients is controversial. Clinicopathologic features and surgical treatment of 6 patients with primary anorectal melanoma were studied retrospectively. There was a male preponderance (2:1) with a mean age of 62 years (range: 34-74). The site of origin of the melanoma was rectal in one patient and in the anorectal junction in five patients. Atypical intramucosal melanocyte proliferation was associated with rectal melanoma. The maximum tumor size from 2 to 5.5 cm. Common initial symptoms were rectal bleeding and/or tenesmus. CT was useful for tumor staging. Two patients had distant metastases at initial presentation. Four patients underwent "curative" treatments by abdominoperineal resection and 2 by local excision. The survival for the group as a whole was poor (mean: 12.6 months; range: 7-30 months). Surgery is the primary option. The prognosis, however, is poor, since metastatic disease is commonly established at presentation. Atypical intramucosal melanocyte proliferation may be a marker in association with tumor sited in the rectum.
