Total Thyroidectomy: the first, the best. The recurrent goiter issue.

BACKGROUND: Redo surgery for recurrent goiter is still now, even in experienced hands, followed by higher morbidity than primary total thyroidectomy. Suppressive Levothyroxine therapy failed to improve the recurrence rate, while inducing a subclinical hyperthyroidism. Aim of this study is to verify morbidity after total thyroidectomy for benign thyroid diseases, both primary and after recurrence. MATERIALS AND METHODS: A series of 20 cases of total thyroidectomy for recurrent benign diseases (RG), performed between January 2001 and December 2013 was compared with 225 cases of primary total thyroidectomy (PT) . Cancers, even incidentally diagnosed, were excluded. At least a 12 months follow up was accomplished. Due to the small size of the sample for RG, statistical analysis was performed by Fisher test only. RESULTS: Postoperative complications were Transient hypocalcemia: 5 (25%) in RG and 18 (8%) in PT, Permanent hypocalcemia only 2 (10%) in RG (significant for p <0,05), Transient RLN deficit 5 (25 %) in RG and 6 (2.6%) in PT (significant for p< 0.05). CONCLUSIONS: Differences in incidence of perioperative complications cannot be advocated to justify a less than total thyroidectomy even in benign disease setting. The need for a redo surgery with its burden of morbidity is per se a good reason to avoid a conservative surgery. Further, suppressive therapy with Levothyroxine often fails to avoid recurrence, inducing in some cases a specific morbidity. Our experience confirms the results of our previous experiences and of literature on this topic: the best management of recurrent goiter is its prevention by primary total thyroidectomy.

A pilot study about the oncologic safety of colonic self-expandable metal stents (SEMS) in obstructive colon cancer: is occlusion always better than "silent" perforation?

OBJECTIVE: To evaluate the oncologic safety of colonic self-expandable metal stents (SEMS) in obstructive colon cancer. PATIENTS AND METHODS: We retrospectively reviewed all the patients who were treated with endoscopic placement of a self-expandable metallic stent (SEMS) at our institution. RESULTS: A total of 26 patients were identified during the study period, of which 24 patients (92.30%) were treated with SEMS as a bridge-to-surgery and 2 (7.69%) as palliation. In 22 cases (80.76%), the stenosis was localized to the left side. Clinical success with resolution of bowel obstructions was achieved in 22 (84.61%) patients within a short period of time. Among patients treated successfully with SEMS insertion as bridge to surgery (n = 22), 20 (90.9%) underwent one-stage surgery with primary anastomosis while 2 patients (9.09%) underwent colostomy due to intraoperative evidence of a covered perforation by cancer tissue in the pelvis. Patients with subclinical perforation developed an early peritoneal carcinomatosis, 10 patients treated with curative intent subsequently developed liver metastasis after 24 months. CONCLUSIONS: We reported an overall poor outcome among patients treated with the insertion of SEMS. This led us to think that, in some cases, occlusion may be better than a "silent" perforation.

Laparoscopic treatment of intrasplenic pancreatic pseudocyst.

INTRODUCTION: Pseudocyst formation commonly follows pancreatitis, but erosion into the spleen is rare and potentially life threatening. We report a case of an intrasplenic pancreatic pseudocyst treated laparoscopically with distal pancreatectomy and splenectomy. METHODS: A 50 year old male with a history of chronic alcoholic pancreatitis, presented with abdominal pain for 3 months, worsening over the past several days. A CT scan showed a broad 9 cm subcapsular fluid collection suspicious for an intra-splenic pseudocyst. The patient underwent laparoscopic distal pancreatectomy and splenectomy. RESULTS: There were no intraoperative complications and the patient was discharged on day 8. The final pathology revealed a benign cystic lesion measuring 9 x 6 x 3 cm that was not communicating with the pancreatic duct, and 2 smaller pseudocysts in the pancreatic body and tail. A previous scan did not reveal any abnormalities in the spleen, and showed the other pancreatic pseudocysts. At 8 month follow up the patients was symptom free, with no new pseudocysts. CONCLUSIONS: Splenic parenchyma involvement is an unusual complication of pancreatic pseudocyst. The optimal treatment is controversial. Percutaneous drainage carries a high recurrence rate and risk of hemorrhage. Open surgery is effective, but associated with significant morbidity. Laparoscopy offers an effective method of treatment without the potential complication of a large abdominal incision.

Lymph node evaluation in gallbladder cancer: which role in the prognostic and therapeutic aspects. Update of the literature.

OBJECTIVE: The widespread use of laparoscopy has changed the outcome of gallbladder cancer as a consequence of increasing referral and incidental discovering of earlier stages cancer. Nevertheless, GBC is still associated with a poor prognosis and lymphnodal involvement is a main prognostic factor, important both for staging and for evaluating surgery quality. No consensus exists about the extension of lymphadenectomy to be performed nor about contraindications to extensive resection. A review of literature was so designed to identify the actual role, extension and limits of lymphadenectomy. MATERIALS AND METHODS: A search on Pubmed and Scopus has been performed using the following keywords: gallbladder cancer, gallbladder neoplasm, surgery, laparoscopy, lymphadenectomy to evaluate the prognostic and the therapeutic role of the lymphadenectomy in gallbladder cancer. The retrieved articles were analyzed aimed to evaluate the impact of lymphectomy and of its extension on overall and disease free survival. RESULTS:  Although no consensus still exists over the extension of ideal lymphadenectomy, some points are already clearly established: a part from T1a neoplasms, that do not require further surgery, and T1b for which a regional lymphectomy (N1) is safe and mandatory, more advanced stages require a more aggressive surgery but the fate of paraortic nodal station is still under evaluation. In fact some Authors still believe that the involvement of these nodes determine a so poor prognosis to make uselessly risky their surgical aggression. Other Authors conversely, show that there is not any difference in survival, among node positive patients, between paraortic node positive and no paraortic node positive patients. CONCLUSIONS: The prognosis of gallbladder cancer remains poor because in most patients the diagnosis is made at an advanced stage. Complete surgical resection provides the only curative treatment option in this disease. In order to improve long-term outcome, several surgeons have advocated aggressive surgical resection, including major hepatectomy, pancreatoduodenectomy and extended lymphadenectomy. Even a para-aortic nodal disease shouldn't discourage from pursuing this objective.

Laparoscopic cholecystectomy: ultrasonic energy versus monopolar electrosurgical energy.

OBJECTIVE: Nowadays, laparoscopic cholecystectomy (LC) is undoubtedly considered the "gold standard" in the surgical treatment of symptomatic gallstones, gallbladder adenomas and acute cholecystitis. Among the alternative energy sources proposed (monopolar, bipolar electric scalpel, radiofrequency sealers) with the aim to dissect and/or seal, the ultrasonic energy has been frequently adopted, however without a widespread acceptance among surgeons for routine or emergency laparoscopic cholecystectomy. This study investigates the possible beneficial aspects of ultrasonic dissection and its efficacy in the closure of the cystic artery and duct. PATIENTS AND METHODS: Patients were retrospectively divided into 2 groups according to the instruments used for division of the cystic artery and duct as well as for dissection of the liver bed: 121 patients in whom dissection and coagulation were performed using monopolar coagulation and 43 patients who were all treated with the ultrasonically activated scalpel harmonic ACE (Ethicon Endo-Surgery) as the sole instrument used in the whole procedure. RESULTS: The mean operative time, was significantly shorter in the harmonic group than in the traditional group (35.36 + 10.15 min vs. 55.6+12.10 vs. respectively; p < 0.0001). The rate of gallbladder perforation was significantly higher in the traditional group than in the harmonic group 20.66% (25 patients) vs. 6.98% (3 patients), respectively; p < 0.05). Intraoperative volume blood loss was significantly more in the traditional group than in the HS group (29.32+14.21 vs. 12.41+8.22; p < 0.0001). The mean amount of postoperative drainage was not significantly different among the two group (18.41+6.54 vs. 15.96+8.69 ml, p > 0.05). No considerable visceral injury has been recorded in either group. The postoperative parameters observed included postoperative hospital stay and morbidity for each group. The hospital stay was not significantly shorter in harmonic group (48.15+4.29 vs. 49.06+2.94 h, p > 0.05). The overall morbidity rate was 14.02 % (not significant). CONCLUSIONS: The use of the harmonic scalpel shows some statistically significant advantages limited to a few intraoperative parameters. We conclude that a wider use of harmonic scalpel not offers such advantages to make it the reference technique.

Dissemination metastasis after laparoscopic colorectal surgery versus conventional open surgery for colorectal cancer: a metanalysis.

PURPOSE: The purpose of this systematic review is to evaluate and compare the risk of dissemination metastasis (wound, port-side metastases and peritoneal seeding) after laparoscopic colorectal surgery and conventional open surgery for colorectal cancer. MATERIALS AND METHODS: The Authors searched relevant randomized controlled trials between January 1998 and July 2012. RESULTS: Wound, port-site metastases and peritoneal seeding were rare and no significant differences occurred between the two groups. The port-site and extraction site recurrence were likely to be the results of suboptimal surgical techniques and occurred in the early phase of the learning curve. The authors also found no significant differences in overall, local and distant recurrences. No significant differences between laparoscopic and open surgery were found in cancer-related mortality during the follow up period of the study (7 RCTs, 3525 patients, 12.8% vs. 14.00%; OR (fixed) 0.83, 95% CI 0.68-1.02), with no significant heterogeneity (p = 0.35). CONCLUSIONS: The literature supports the implementation of laparoscopic surgery into daily practice. Laparoscopic surgery can be used for safe and radical resection of cancer in the right, left, sigmoid colon and rectum. However further studies should address whether laparoscopic surgery is superior to open surgery in this setting.

Adrenal pseudocyst as a cause of postpartum abdominal pain.

Among adrenal masses only 0.06% to 0.18% are cysts and among them, pseudocysts are the second (39%) most common lesions. Due to the increased use of imaging studies their incidence seems to have increased. Most of these lesions are incidentally found during radiologic investigation or at the time of autopsy, and only rarely they are detected in pregnant women. The latter scenario warrants emergency surgery, due to the risk of rupture. We present a case of a 39-years old woman presenting with unrelenting left flank pain due to a large adrenal pseudocyst soon after her first delivery. Four months after, she presented to our surgical division for persistent pain and anemia so underwent an extensive work up that showed a large pseudocystic mass (8 x 8 cm ) of the left adrenal gland. Once the neoplastic and parasitic etiology of the lesion were excluded, she underwent uneventful laparoscopic adrenalectomy. She was discharged home three days postoperatively. This case is the 13th case in the English literature and at the same time is the first case of adrenal pseudocyst occurred four months after delivery.

Diet and pancreatic cancer: many questions with few certainties.

UNLABELLED: BACKGROUND, OBJECTIVES: Pancreatic cancer ranks fourth for cancer mortality for men and women in the United States. This is a particularly devastating cancer since the case-fatality proportion approaches 90% within 12 months following diagnosis. Therefore, understanding the etiology and identifying the risk factors are essential for the primary prevention of this deadly disease. Of the few potentially modifiable risk factors that have been identified, cigarette smoking, history of diabetes mellitus, and obesity seem to be among the most consistent, but the effect of dietary factors is still unclear. The aim of our study is to review of the literature examining the potential role of carbohydrates, fatty acids, meat, fruit and vegetables, alcohol. DISCUSSION: Although large prospective cohort studies with questionnaire based analyses will continue to have much to offer in defining predisposing factors for difficult diseases, such as pancreatic cancer, unfortunately dietary questionnaires do not reflect the bioavailability of the nutrients from various foods, the level of absorption from the digestive tract, or individual differences in metabolism. CONCLUSIONS: Greater use of participant-derived biological samples, banked plasma, germline DNA, and tumour tissue samples may help to the understanding of pancreatic cancer pathogenesis.

An unique case of dyspareunia leading to the diagnosis of urachal cyst in a nulliparous 28-year-old woman.

Urachal cysts are usually asymptomatic. Symptoms, when present, are usually acute abdominal pain, fever, midline hypogastric tenderness, palpable mass, evidence of urinary infection or haematuria due to infection of the cyst. We report an unique case of dyspareunia and "abdominal fluid flowing feeling" caused by an urachal cyst in a 28 year-old nulliparous woman. Diagnosis was achieved by US and MRI. Cystography excluded any cyst-bladder communication. Laparoscopic surgery was performed without perioperative complications. Patient obtained immediate relief of symptoms still continuing at a 24 months follow up.

Gallbladder metastases of breast cancer: from clinical-pathological patterns to diagnostic and therapeutic strategy.

Gallbladder metastasis of breast cancer are rare, particularly linked to lobular histotype and synchronous just in 1/4 cases. A review of the literature has been performed aimed to evidence the patterns of gallbladder metastases of breast cancer finding 15 cases to whom we added a 48 years old post-menopausal woman. 3 weeks after surgery for mixed ductal-lobular breast carcinoma she showed at the abdominal ultrasound, performed for staging, diffuse thickening of the gallbladder wall , coherent with a chronic cholecystitis and with the mild right-upper-abdominal pain that the patient complained in the last months. After laparoscopic cholecystectomy, the pathology report showed a metastatic lobular carcinoma of the breast. Two years later she presented with SNC metastases and died four months later. Lobular histotype is the most frequent breast neoplasm associated with gallbladder metastases. Usually metachronous, these metastases are sinchronous in 28% of cases. Symptoms are usually linked to coexisting acute or cronic cholecystitis. Rarely massive invasions lead to acute abdomen or jaundice. Imaging is rarely diagnostic for neoplasm. Our experience and data from literature lead to careful evaluate every anomaly observed in breast cancer patients. A careful evaluation of abdominal symptoms and of routine imaging examinations performed for staging and for treatment planning, could consent to detect and radically treat the metastases and appropriately assign the chemotherapy. Such approach can lead to discrete survival even in these unfortunate patients. Surgeons and gastroenterologists should be aware of the risk hidden behind apparently benign, mild diseases in such patients.

Retrospective survey on laparoscopic cholecystectomy in the cirrhotic patient.

Cholelitiasis is a common disease in patients with liver cirrhosis, mainly due to intravascular haemolysis and functional alterations of the gallbladder. In Child A and B cirrhotics laparoscopic cholecystectomy (LC) demonstrated the same advantages and safety as in the non cirrhotic patients. On the contrary, indications for surgery in Child C patients should be carefully evaluated. Nevertheless, the current number of patients with Child C cirrhosis submitted to LC is too low to extrapolate definitive data. Here we report our observations on a retrospective case series of LCs performed for symptomatic biliary disease in patients affected with liver cirrhosis. Both medical records and surgical registers were used to collect pre-operative, intra-operative and post-operative data from 40 cirrhotics out of 921 patients operated by laparoscopic cholecystectomy between November 1996 and November 2006. All patients underwent LC because of symptomatic disease. The average duration of the laparoscopic intervention was 111 minutes (60-220 minutes) distributed as follows according to the severity of liver disease: 66 minutes (48-87) in the Child A group, 108 minutes (91-119) in the Child B group and 138 minutes (110-160) as refers to Child C cirrhotics. Median blood loss was quantified as 80 ml (28-97) in Child A group, 155 ml (130-180) in Child B group and 300 ml (220-500) among Child C cirrhotics. The median length of hospital stay was 6 days (3-9 days) in the Child A group, 9 days (7-13 days) in the Child B group and 21 days (16-27 days) in Child C cirrhotics. Three cases out of 40 (7,5%) died: 2 Child C and 1 Child B. In conclusion, this study confirms that in patients affected with Child A and B cirrhosis LC may be safely performed either in emergency or in election whereas as refers to Child C cases we have observed a slightly higher mortality but a relevant higher impact of non lethal complications.

A case of branchial cyst with an ectopic thyroid papillary carcinoma.

We report the fifth case worldwide described of thyroid papillary carcinoma arising in a branchial cyst. A metastatic lesion from occult primary thyroid carcinoma has to be ruled out. The embryology of this cervical lesion is also discussed in order to point out the diagnostic criteria and the therapeutic guidelines.

A pure primary squamous cell breast carcinoma presenting as a breast abscess: case report and review of literature.

We report the fourth worldwide case of pure primary squamous cell carcinoma of the breast presenting as an abscess. An inflammatory breast lesion in postmenopausal woman must be suspected as a malignant one and drainage of the abscess has to be followed by an accurate excision. The finding of a pure squamous cell carcinoma bears the necessity of an accurate diagnostic work up, to exclude a skin lesion or a metastasis from other district. Also histological criteria are discussed. More difficult to outline therapeutic options, due to the rarity of disease and great difference in outcome observed.

[Prolassomucosectomy according to Longo. Intermediate results]. / La prolassomucosectomia sec. Longo. Risultati a medio termine.

We present results obtained in our first series of 25 patient treated by prolassomucosectomy for haemorrhoidal prolapse with a follow up of 18-36 months. Control of the disease and functional results proved to be optimal. After small early haemorrhages from the suture line, we started adding stitch sutures with haemostatic intent to all three vascular pedicles. Early or late additional complication were not observed.

Adult intestinal intussusception: a case report of a rare clinical entity.

Intussusception in adult is a rare entity that challenges the surgeon opening a wide range of issues in order to define the etiology and therapeutic strategy. Whether to resect or not the bowel is the main question. The answer can be given only after having seen the site of obstruction and the etiology. Colonic intussusception is best treated by resection. Also small bowel intussusception can require resection if a neoplasm is the cause. Peutz Jeghers can be one of these causes as is seen in the case we report.

Perforation of a ureteral diverticulum: a case report and review of the literature.

The ureteral diverticulum represents a rare pathology. It is infrequently symptomatic and even more infrequently it manifests itself as an acute event. To our knowledge this is the only case described in the literature of perforated ureteral diverticulum with consequent uroperitoneum.

Nonparasitic cysts of the liver: laparoscopic treatment and long-term results.

BACKGROUND: In the current debate on the indications for the laparoscopic treatment of symptomatic simple hepatic cysts, we emphasize the importance of the exact indications, practicing in an area endemic for hepatic hydatidosis. 8 years ago we started treating laparoscopically the simple hepatic cysts and the polycystosis. Although the laparoscopic approach to parasitic hepatic cysts has been recently introduced, this method has to be the result of a conscious choice and with a presumptive diagnosis to support it. In fact, reviewing the literature on the subject, we realized how most of the intraoperative complications were due to an erroneous preoperative diagnosis, likely to be attributed to the infrequent observation of hepatic hydatid disease. Hence, it seems of primary importance to review the subject in light of the potential dangerous aspect of the laparoscopic approach. METHODS: From 1992 to 2000 we treated 38 cases of benign liver cystic disease (29 echinococcal cysts, 8 symptomatic simple cysts, 1 polycystosis). Due to the endemic nature of the disease in our territory, the preoperative diagnosis was very meticulous (ultrasonography, CT scan, MRI, serology...). Only 9 cases with a preoperative diagnosis of simple cyst or polycystosis were treated with laparoscopic wide fenestration, combined with cholecystectomy in three cases. The follow-up consisted of ultrasonography in the majority of cases and CT scan in 2. RESULTS: All the 9 laparoscopic cases were uncomplicated and no conversions to open procedures have been recorded. The final pathology confirmed the initial diagnosis in all cases. The follow-up ranged between 1 and 8 years and complete remission has been obtained. CONCLUSIONS: The results of this study demonstrate how a meticulous preoperative clinical evaluation can avoid intraoperative complications, making the laparoscopic approach to non-hydatid hepatic cystic disease safe and efficacious. Although laparoscopy is indicated in parasitic liver pathology, the technical approach is very different from the simple cystic disease. In the former, in fact, hepatic resection or pericystectomy are utilized, the results of which have been currently evaluated and compared with the open technique on a large scale on several ongoing trials.

Ductal carcinoma in situ (DCIS) of the breast: thirty-two consecutive cases under 50 yrs detected by mammography: treatment and results.

Thirty-two consecutive cases of ductal carcinoma in situ of the breast in women under fifty are presented. Diagnostic procedure, pathological aspects, treatment and outcome are reported. All the patients had their cancer diagnosed by mammography. The tumor was marked by stereotactic or ultrasound guided localization. Lumpectomy without axillary node dissection was the surgical treatment of thirty lesions with good cosmetic results; radiation therapy was advised in all of these cases. In two cases mastectomy with immediate reconstruction was performed because of the multifocality of the cancer, none of the patients experienced local or distant recurrence. This experience emphasizes the importance of mammographic screening for women 40 years of age, in fact this approach allowed the diagnosis of a large number of DCIS. A correct definition of the problem and a multidisciplinary therapeutical approach is warranted to prevent the high local recurrence rate reported in the past.

Spontaneous rupture of a giant hemangioma of the liver.

Hemangiomas are frequent benign tumors of the liver. Symptoms (abdominal pain and fullness) are mostly seen in giant lesions. Rupture is the most severe complication, can occur spontaneously, with intraperitoneal bleeding, in 1-4% of hemangiomas and has been described in about 30 cases in the international literature with a high mortality (about 60%). This complication is the principal indication for surgery. Although spiral CAT scan and MR are actually the most efficacious imaging methods for study of liver hemangiomas, after Echography, emergency techniques that allows a simultaneous therapeutic approach--as is angiography--are preferable. Trans-arterial embolization (TAE) is in fact useful to stop bleeding and then to perform a safer surgery. A successful embolization can delay the surgical resection of the hemangioma for the time necessary to recover from the hemodynamic distress. Aside from the success of angiographic approach, surgery remains mandatory, effective in stopping the bleeding and in preventing re-bleeding or other complications of TAE such as abscess, fever, etc.. Intraoperative echography currently is the best method to identify vasculo- biliary anatomy and to perform a correct resection. The absence of risk factors for spontaneous rupture of liver hemangiomas, makes this event unpredictable. The best treatment for non-ruptured hemangiomas is still controversial but surgery is usually limited to symptomatic tumors larger than 10 cm.

Cystic dilatation of common bile duct. Case report and review.

The cystic dilatation of the common bile duct is a rare disease in Europe and in the USA; even rarer in adults. In fact less than 30% of cases are described in the over 20's. There are some reports in the elderly. When observed in adults the diagnosis is usually due to the onset of symptoms of associated pathologies or to complications such as cholangitis or cancer. Ultrasound, CT and ERCP allow, in the majority of cases, an adequate pre-operative characterization of the lesion. Intra-operative cholangiography verifies the completeness of surgery--always resective--and excludes residual biliary pathologies. The treatment in patients who already underwent conservative surgery is more complex, in fact, in symptomatic patients a second observation and resection is mandatory while in asymptomatic patients a careful and complete follow-up is adequate without underestimating the cancer risk. Septic and inflammatory complications, especially if chronic or recurring, can damage the liver; here resection or liver transplantation can be necessary. The case here reported is a 24-year-old woman with recurring cholangitis for at least 2 years in which US, CT and ERCP showed a Todani's type I cystic dilatation of the CBD. The total excision of the cyst with hepatic-jejunal anastomosis was carried out. A two-year follow up demonstrated no symptoms and normal laboratory findings; cholangioscintigraphy showed a good hepatic-biliary and anastomotic function.
