[Incidental diagnosis of caecum adenocarcinoma due to retention of endoscopic videocapsule: a clinical case].

Capsule endoscopy is a new technique for the study of small intestine particularly in cases of obscure gastro-intestinal bleeding or chronic iron-deficiency anemia. In our study we present a case of 62 years-old man with a chronic iron-deficiency anaemia developed at least six months before and refractory to iron therapy. The patient was submitted to upper gastro-intestinal endoscopy and to partial colonscopy due to abdominal adhesions for previous abdominal surgery.

[Nerve sparing total mesorectal excision for rectal cancer. Technical notes and results].

Objective: To evaluate the quality of life after nerve sparing total mesorectal excision for rectal cancer.

Patients And Methods: Crucial technical aspects of the procedure such as the preservation of genitourinary innervation and the achievement of optimal local control of the disease have been emphasized. It is known that local recurrences, sexual and urinary dysfunctions may have a significant impact on postoperative quality of life of the patients.

Surgical management of substernal goitres. When is sternotomy inevitable?

Purpose: Aim of this retrospective study is to report personal experience in the surgical management of substernal goitres emphasizing the guidelines for preoperative planning of sternotomy in selected cases.

Patients And Methods: Medical records of all patients (n=355) submitted to thyroidectomy for struma in our Operative Unit, between 1993-2003, were analysed. A substernal goitre was defined as a goitre having a significant retrosternal extension (>50%) requiring mediastinal dissection.

Improvement in the fertility rate after placement of microsurgical shunts in men with recurrent varicocele.

Objective: To evaluate the effectiveness of microsurgical shunts for secondary varicocele repair after ligation-like procedures, focusing on long-term functional outcomes.

Design: Long-term survey (mean follow-up, 8.5 years) of infertile men after secondary microsurgical reconstructive varicocelectomy.

[Transfixed stitches for the treatment of haemorrhoids].

Nowadays the proctologist has the opportunity to perform various different surgical techniques for the treatment of hemorrhoids. Circumferential mucosectomy with a stapler, diathermic hemorrhoidectomy with high frequency devices, and the HLA doppler II system have significantly modified the classical indications for the treatment of the disease. There is, however, still no general consensus as to the indications for the use of each of these techniques in clinical practice, giving rise to confusion among specialists and an inappropriate use of health care resources.

Potentially fatal bleeding in acute pancreatitis: pathophysiology, prevention, and treatment.

Introduction: Massive bleeding may complicate the course of either acute or chronic pancreatitis. Although the latter is more frequently involved when bleeding occurs in the acute form, a poorer prognosis is to be expected. Abscess, severe inflammation, regional necrosis, and pseudocysts may cause major vessel erosion, with or without pseudoaneurysm formation, whose eventual rupture may result in massive bleeding into the gastrointestinal tract, retroperitoneum, and peritoneal cavity.

Wirsung and Santorini: the men behind the ducts.

During the 16th and 17th centuries, several important discoveries were accomplished by anatomists whose contribution has enlightened the most important anatomic structures of the pancreas. Following the earliest discoveries, researchers of several medical specialities further investigated the ductal pancreatic system. The accessory pancreatic duct with its minor papilla, the main pancreatic duct and the papilla major along with the confluence of the main pancreatic duct with the bile duct and pancreas divisum, have been the objects of interest of several personalities of the medical history.

[Benign thyroid disease: 20-year experience in surgical therapy].

This retrospective study compares recurrence and postoperative complication rates after isthmo-lobectomy and subtotal thyroidectomy (group I) vs near-total and total thyroidectomy (group II) for benign thyroid disease. Seven hundred and forty-three patients were operated on for thyroid diseases over the period from 1977 to 1998. We considered 202 patients operated on for benign thyroid disease from 1988 to 1998.

An improved technique for temporary diverting ileostomy.

A modification of the Turnbull technique for a temporary diverting ileostomy, which may be also applied to diverting colostomies, is described herein. According to the technical modification described, a totally diverting ileostomy is performed with the help of a Foley catheter secured in the subcutaneous tissue, and pulled upward and to the right like a sling around the efferent loop. This simple modification allows for better protection of distal anastomosis and an optimal diversion of enteric transit.

A simple ultrasonographic test for preoperative haemodynamic evaluation of varicocele.

According to the haemodynamic classification of varicocele type I is caused by renospermatic reflux due to a proximal nutcracker phenomenon or to valvular insufficiency of the left internal spermatic vein. Type II is due to ileospermatic reflux and type III may be characterized by a combination of I and II refluxes. Although this classification proposed by Coolsaet is precious for decision making, it is seldom used in clinical practice being based on a complex angiographic evaluation which is invasive and exposes the patient (often a teenager or with infertility disturbances) to excessive radiations.

Long-term results of microsurgical drainage for idiopathic varicocele.

The long-term results of microsurgical shunts for idiopathic varicocele are reported in the present paper. Sixty-two patients with a total of 65 varicoceles (three were bilateral) were followed up for 1 to 8 years. Pre- and postoperative ultrasonographic evaluation of varicocele size was considered of great importance in order to reduce the bias of subjective clinical diagnosis and to achieve a reliable and objective follow-up.

[History of reconstruction following total gastrectomy].

Near a century after the first successful total gastrectomy for gastric cancer, the authors review the various technical proposals for digestive tract reconstruction following total gastrectomy. Following a classification based on duodenal circuit, on the viscerum employed and on the creation of pouches and/or anti-reflux mechanisms, pros and cons of the various classes of reconstructions are clearly depicted, suggesting the reasons that made Roux-en-Y esophago-jejunostomy and jejunal interposition the most used reconstructive procedure in worldwide clinical practice.

Severe hemorrhagic complications in pancreatitis.

Severe bleeding may complicate the course of either acute or chronic pancreatitis, the latter being more frequently involved. Pseudocysts, severe inflammation, regional necrosis and infection may cause major vessel erosion with or without pseudoaneurysm formation which eventually may result in severe bleeding into the gastrointestinal tract, retroperitoneum and peritoneal cavity. The AA report their experience on 8 cases and analyze the data of a comprehensive review of 389 cases of massive bleeding reported in the literature during the last 100 years until December 1993.

[Massive pseudocysto-jejunal hemorrhage caused by rupture of pseudoaneurysm of the splenic artery].

The authors report a case of massive intestinal hemorrhage caused by rupture of a splenic artery pseudoaneurysm into a pseudocystojejunostomy. The pathologic and clinical features of this unusual complication of pancreatitis are discussed. One hundred and seventy one cases of major bleeding associated with pseudocysts and/or pseudoaneurysms have been reported in the literature during the period 1989-May 1991.

Surgical anatomy of the papilla of Vater and biliopancreatic ducts.

The present research was aimed at defining the surgical anatomy of the biliopancreatic ducts and of Oddi's sphincter. The numerous anatomic variations of the papilla, the millimetric distribution of its muscle fibres, and any morphological detail of clinical significance have been investigated. An integrated analysis of radiographic, tridimensional (casts), and histologic findings has been carried out in 49 of 64 autoptic bilio-duodenopancreatic specimens.

Is intraoperative ultrasonography useful in pancreatic cancer surgery?

Preoperative staging of pancreatic cancer represents a major challenge for a suitable surgical management of the disease. In a consistent number of patients laparotomy is still necessary in order to decide whether the tumor is resectable or not. In the present paper the Authors report their experience with intraoperative ultrasonography (IOU) in evaluating pancreatic cancer resectability.

[Surgical treatment of 4th-stage hemorrhoids: the role of anatomical techniques].

Surgical options for fourth-degree hemorrhoids are still matter of debate. The high incidence of the disease encouraged research and brought to technical improvements able to achieve a painless, reliable, harmless and well tolerated surgical treatment. The Authors report a retrospective study of 193 patients who underwent surgery for fourth-degree hemorrhoids.

Circumferential choledochoplasties with autologous venous and arterial grafts.

Circumferential choledochoplasties with vascular grafts have rarely been attempted either experimentally or in clinical practice. In this study, choledochoplasties using autologous venous and arterial grafts were performed in rats. Sixty-four rats were randomly selected into five treatment groups: A) venous interpositional graft replacement of a choledochus gap without a stent; B) venous graft with prolene stent; C) venous graft with polyethylene stent; D) arterial graft; E) a control group with simple resection between ligatures in the choledochus.

[Technique and immediate results of the Moreno Gonzalez-Carboni reconstruction after total gastrectomy].

Reconstruction following total gastrectomy for gastric cancer is still matter of debate. The Roux-en-Y esophagojejunostomy and the interposed loop esophago-jejunoduodenostomy are the techniques commonly employed. The Authors describe their modification of Henley's jejunal interposition and report early results achieved in a series of 60 consecutive patients.

Colonic involvement in pancreatitis. Six cases more.

Lesions of the colon are generally considered to be sequelae of pancreatitis. They include: localized paralytic ileus (colon cutoff sign), necrosis, fistulae, stenosis and varices. On the basis of an extensive review of the literature (332 cases), it is suggested that the real incidence of these lesions is significant.

[Telescopic termino-terminal pancreatico-jejunostomy after duodenopancreatectomy].

The Authors report their experience in pancreatic stump management after pancreaticoduodenectomy. "Telescope" end-to-end pancreaticojejunostomy realized with some safe technical details represents a valid reconstructive procedure especially when the pancreatic remnant has a normal parenchyma without dilated duct.
