Sporadic pedunculated duodenal adenomas. Clinical presentations and endoscopic management: a case series.

The prevalence of sporadic duodenal polyps is estimated to be 0.3%-4.6% in patients referred for an upper endoscopy. Most of patients are asymptomatic (66-80%) at the time of diagnosis though bleeding, anemia and abdominal pain are the most commonly reported symptoms. These are related to the polyp's size, location and histological characteristics. We describe three cases of big, pedunculated nonampullary sporadic duodenal polyps (tubulovillous low-grade dysplasia adenomas) located in the second part of the duodenum and characterized by different clinical presentations, managed in our Endoscopic Unit within one year (between 2016 and 2017). Polypectomies were performed, either piece-meal or en-bloc using various endoscopic instruments. In one of our patients (case 1), a delayed bleeding (36 hours after the procedure) occurred eventually managed conservatively with two units of blood transfusion. In the same patient, in the following months after polypectomy, the pre-procedural state of anemia misclassified as Mediterranean anemia has improved with a significant rise of hemoglobin value (14.1g/dl). In a patient who previously underwent a renal transplant (case 2), endoscopy was indicated, based on the positive fecal occult blood test. In another patient (case 3), a big polyp induced pancreatitis since it exerted a strong traction on the duodenal wall during peristaltic movements. The removal of the polyp has led to the resolution of pancreatitis and associated symptoms.

[Nerve sparing total mesorectal excision for rectal cancer. Technical notes and results]. / Nerve sparing total mesorectal excision per neoplasia del ret- to. Note di tecnica e risultati.

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. Postoperative evaluation of functional outcomes of nerve sparing total mesorectal excision has been carried out utilizing the QLQ C30 (version 3) (All CR38). RESULTS: At one year follow-up 27.2% of the patients presented sexual activity related dysfunctions, 6.1% complained of urinary dysfunction and 21% of the patients complained of some significant psychologic disturbances. CONCLUSIONS: A correct surgical dissection with preservation of inferior hypogastric plexus and all genitourinary nerve supply yield the best results either in terms of quality of life and of oncologic control of the disease.

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. RESULTS: A total of 18 out of 355 patients undergoing thyroidectomy for struma in our Operative Unit had substernal goitres. The most common symptoms, at presentation, were the presence of neck mass and respiratory disorders. Standard cervical incision was adequate to achieve total thyroidectomy in 17 cases while, in one patient with computed tomography images showing the presence of a huge goitre extending below the aortic arch, a sternotomic approach was inevitable to ensure safe removal. No major morbidity or perioperative deaths occurred. One patient with scleroderma experienced bilateral paralysis of laryngeal nerves for two months, with full recovery thereafter. CONCLUSIONS: While removal of the majority of substernal goitres can be achieved by means of cervical incision, this approach is not always safe. In a selected number of cases with an iceberg shaped substernal goiter and with >70% of the volume lying below the thoracic outlet, a sternotomic approach is inevitable. Preoperative diagnostic work-up should, thus, include chest X-ray and computed tomography. Overall results in the present patient population, have been excellent since morbidity has been minimal and mortality absent, and all patients are symptom free.

Microsurgical treatment of varicocele: selecting most appropriate shunt.

Microsurgical drainage of spermatic veins tailored to the hemodynamic type of varicocele was performed in 20 patients. In 14 cases the procedure was indicated as prophylaxis and in 6 cases as treatment of infertility. Complete regression of varicosities was observed in 75 percent as early as six days postoperatively, in 85 percent at two weeks, and in 90 percent at twelve months. In the remaining 10 percent, a consistent reduction of varicocele was found. No patient experienced progression of the disease. Eighty-three percent of the patients with altered seminal parameters showed an improvement of them at a mean follow-up of 9.1 months.

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. Exact limits of the choledocus and Wirsung sphincters were defined. A consistent accumulation of circular muscle fibres could be seen, on the choledocus duct side, up to a mean distance of 13.6 mm from the papillary pore. However, more rarefied fibres were present up to 20.5 mm. Muscle fibres were seen to stop roughly on the pancreatic duct side at 7.3 mm from the papillary pore. The beginning of the sphincter was observed 2-3 mm above the papillary pore. There was no evidence suggesting the presence of upper, middle, and lower biliary sphincters. Five anatomic diversities of the Wirsung-choledocus confluence were found. The Y type was the most frequent (61.2%), followed by the U type (22.4%), V (14.3%), and II (2.1%). Santorini's duct with a normal papilla was present in 16 per cent of the cases. These data along with other interesting observations on antireflux mechanisms (Santorini's valves) and on the ductal space orientation appear to be useful guidelines for a physiopathological understanding of bilio-pancreatic diseases and for any therapeutic procedure on these structures.

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. Microsurgical shunts were tailored to the type of reflux: renospermatic (76.9%), iliospermatic (10.8%) or mixed type (12.3%), 94% of patients experienced a complete morphologic disappearance of varicosities, while in 6% of the cases a consistent reduction of size was objectified although varicosities were still detectable at ultrasonographic examination. In patients with severe infertility a significant increase of seminal parameters was observed postoperatively and this improvement showed a higher statistical significance in patients aged < 30 years.

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. The aim of the present study was to work up an original ultrasonographic test for preoperative haemodynamic evaluation of varicocele in order to indicate the most appropriate microsurgical treatment. Sixty-three patients underwent a preoperative clinico-echographic dynamic test which allowed to classify 76.9% of the cases as haemodynamic type I, 10.7% as type II and 12.3% as type III. Microsurgical shunts were performed in all cases and evaluation of recurrences was accurately carried out with ultrasonographic measurement of residual varicosities. In 6% of the cases varicosities were consistently reduced in size and in 94% absence of varicosities was demonstrated. Varicocele increased in size or was unchanged in none of the cases. In conclusion the test hereby described was shown to be simple and easily reproducible. It allowed a haemodynamic and objective classification of varicocele offering a unique opportunity for tailoring to the individual patient the most appropriate treatment. Furthermore, ultrasonographic postoperative follow-up is the most reliable and objective method to control the "true" incidence of post-varicocelectomy recurrences.

[Massive pseudocysto-jejunal hemorrhage caused by rupture of pseudoaneurysm of the splenic artery]. / Hemorragia pseudoquisto-yeyunal masiva por rotura de pseudoaneurisma de la arteria esplénica.

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. Acute and chronic pancreatitis may be the underlying etiologies and the overall mortality rate of this complication is 35.1%. According to the authors experience, angiographic localization of the bleeding sources and steel coil embolization play a key role in the diagnostic and therapeutic approach to what is generally regarded as the most rapidly lethal sequelae of pancreatitis.

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. Mortality rate seems to be related to the etiology of the bleeding along with its localization and the underlying anatomo-pathologic findings. In patients with chronic pancreatitis it is 22% while in patients with acute pancreatitis or chronic pancreatitis with acute exacerbation it is 60.4% and 57.1% respectively. Splenic, gastroduodenal and superior pancreaticoduodenal arteries are the most commonly involved vessels being associated respectively with a mortality rate of 20.5%, 27.9% and 46.1%. Massive haemorrhage complicating infected necrosis or abscesses implies a worse prognosis when compared to severe bleeding associated with pseudocyst with or without pseudoaneurysm. The increasing use of diagnostic and interventional radiology appears to be the way forward to improve survival rates. Awareness of high risk predisposing condition, activism in achieving an early identification of the bleeding sources, and eventually its angiographic control are essential guidelines for successful approach to the most unpredictable complication of pancreatitis. When embolization fails or is followed by recurrence of hemorrhage, definitive surgical procedures should be immediately instituted.

[Telescopic termino-terminal pancreatico-jejunostomy after duodenopancreatectomy]. / La pancreatico-digiunostomia termino-terminale telescopica dopo duodenocefalopancreatectomia.

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.

[Occlusion caused by colo-rectal carcinoma: personal experience]. / L'occlusione da carcinoma colo-rettale: esperienza personale.

In the last 12 years 25 patients affected with obstruction from colorectal carcinoma were treated. Mortality following simple colostomy was not different from that of surgical resections (25% vs. 14% in Authors' experience). Major surgery (subtotal colectomy) registered a reasonable mortality rate (5-6%).

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. Very important data for intraoperative decision making were obtained in 37.9% of the patients, useful information in 31%, while in 31% IOU may be looked forward to as an important aid in decision making and for a safely guided dissection.

[Efficacy and safety of a salsobromoiodic gel solution in proctological surgery]. / Efficacia e sicurezza di una soluzione salsobromoiodica in chirurgia proctologica.

BACKGROUND: Surgical procedures for ano-rectal pathologies are always conditioned by an high percentage of side-effects. Indeed, the prevention of probable complications such as the non tissue-recovery or infection is a fundamental topic to guarantee an adequate follow-up. The aim of this comparative study is to assess the short-term outcomes of the use of a solution salsobromoiodic gel solution in postoperative period of patients undergoing proctological surgery. MATERIALS AND METHODS: The authors selected retrospectively a population of 80 patients, undergoing surgery for Milligan-Morgan hemorrhoidectomy. Based on the recommended medications postoperatively, patients were divided into two groups: the Group A applied the salsobromoiodic solution gel on the perianal surgical wound in the postoperative period, the Group B did not use any medical facility with the exception of a soap at neutral pH. The clinical features assessed at 5, 10, 15 and 30 days after surgery were: pain, burning and itching lenght, the healing time, the presence or absence of early or late superinfection, the time of re-epithelization, the need for surgical curettage. The subjective evaluation of quality of life was assessed using a Visual Analogue Scale (VAS). RESULTS: There was a statistically significant reduction in length of postoperative pain in patients of Group A compared to Group B (5.6 vs 10.4 days respectively; p<0.005). There was a more rapid wound healing and re-epithelialization in group A, 15 and 21,3 days, respectively, as compared to Group B, 22.9 and 31.7 days (p<0.005). There were no differences between the two groups in terms of burning, itching and early and late bacterial infection. Two patients in Group B required a surgical debridement of the wound. Patients who used postoperatively salsobromoiodic solution declared a better quality of life. CONCLUSIONS: The use of salsobromoiodic gel solution in the postoperative proctological surgery, resulted safe and was effective in reducing postoperative pain, in contributing wounds healing and improving the quality of life, as subjectively assessed by each patient.
