The diagnosis of incidental thyroid carcinoma in patients submitted to thyroidectomy for a benign disease is quite frequent. A retrospective analysis was performed on 240 patients submitted to surgical intervention in order to establish the incidence of the carcinoma. One hundred sixty five patients (68.75%) were affected by benign disease (132 multinodular goiter, 30 uninodular goiter, 2 Plummer and 1 Basedow) and 75 (31.25%) by carcinoma. In 30 of 165 patients (18.2 %), affected by benign disease, occurred a histological diagnosis of thyroid carcinoma, (18 papillary carcinoma, 6 follicular carcinoma, 5 papillary carcinoma follicular variant and 1 oncocytic carcinoma). In this study it's considered incidental thyroid carcinoma the one occurred in patients who never underwent FNA and there were no suspicious features in all exams that may suggest the presence of carcinoma. Fifteen of the 30 incidental carcinoma (50%) were microcarcinomas; in the other 13, dimensions were more than 1 cm, but less than 2 cm in 9 cases. Two patients had a synchronous carcinoma. Actually these patients are still in a follow up program and no recurrency of disease is occasionally observed. This study shows that the only way to put doubts on the real benignity of the disease is the fine needle aspiration; there are no other instruments that could let think about the occurrence of the carcinoma. Moreover in the majority of cases the incidental carcinoma is a microcarcinoma, it doesn't reach significant volume, may be not centered by a FNAB, but in must cases it's not really biologically aggressive.
The advantages and applications of the videolaparoscopic technique (VL) versus open surgery in the treatment of acute and complicated appendicitis are not well defined. Our study examined 150 patients, 67 males and 83 females. They underwent surgery for acute appendicitis in emergency. The choice between open or laparoscopic tecnique was due to patient's clinical conditions and surgeon's experience. Two of these patients had no infiammatory process. Eleven patients were affected by gynaecological diseases. The last 137 patients underwent surgery for acute appendicitis and the diagnosis was confirmed. Among them, 35 (25%) were affected by a complicated appendicitis with diffuse or clearly defined peritonitis. In 134 patients the surgery was completed laparoscopically. The conversion rate was 2%. Morbility rate was 3%, due to intra abdominal abscesses secondary to acute complicated appendicitis. The mean operative time was 76 min and the mean hospital stay was 4.8 days. The death rate was 0%. In our experience, laparoscopic appendectomy has significant advantages over traditional open surgery in both acute and complicated appendicitis, especially in young women. In this way, we can diagnose pelvic disease that could be characterized by the same symptoms of acute appendicitis, then we suggest laparoscopic appendectomy even just to complete the diagnostic iter. Laparoscopy is useful in terms of convalescence, postoperative pain, hospital stay, aesthetic outcome and an easier exploration of the peritoneal cavity.
Although in most cases the diagnosis of acute appendicitis is straightforward, not all patients experience typical symptoms and other conditions may mimic appendicitis. In fact, 15-25% of appendectomies involve the removal of a normal appendix. To date, there is no literature evidence that herniation pit (HP) may mimic acute appendicitis. We report a case of a 30 year old woman admitted to the Emergency Department for severe, acute pain developing a few hours earlier in the lower right fossa, with irradiaton to the right thigh. She did not present any fever, nausea or vomiting, Blumberg's sign was absent but the psoas sign and obturator sign were both positive. WBC count was 16,000/mm3 and the Alvarado score was 4. Biochemistry profile was normal. US was unclear and transvaginal ultrasound did not show any gynecological disease. CT scan showed only an herniation pit of the right femoral neck. The patient was admitted to an orthopedic ward and treated with anti-inflammatory therapy. She was discharged after 2 days without any pain and in good conditions. Our case demonstrates that herniation pits of the right femoral neck should be considered a potential cause of right lower abdominal pain mimicking acute appendicitis, particularly if the psoas sign and obturator sign are positive and the patient is physically active.
Colorectal foreign bodies per annum introduced are not exceptional. They can be classified as high-lying or low-lying, depending on their location relative to the recto-sigmoid junction. High-lying rectal foreign bodies sometimes require surgery; low-lying ones are often palpable by digital examination and can removed at bedside. No reliable data exist regarding the frequency of inserted rectal foreign bodies and the literature is largely anecdotal. We review our experience on patients almost all males and heterosexual with retained colorectal foreign bodies and their outcome in Surgical Emergency Unit of a Southern Italy University hospital.
Patients with gallstones are often affected by alimentary disorders contributing to the onset of gallstones disease. Cholecystectomy can have nutritional and metabolic consequences in the short-term (diarrhea, abdominal pain and bloating) and in the long-term (increased Body Mass Index with metabolic syndrome, gastritis, liposoluble vitamin deficiency). Pathogenic mechanisms behind these disturbances are reviewed and the need for an early post-operative nutritional intervention based on low-lipid, high-fibers diet, is highlighted.
BACKGROUND: Even if endometriosis is usually an exclusively gynecological issue, atypical locations fall within the interest of general surgery. The aim of our retrospective study focuses on the need for surgeons to face this rare condition, in order to avoid unnecessary or inadequate treatment. METHODS: We retrospectively analyzed clinical presentations, previous endometriosis diagnosis and surgical acts on a group of 60 patients, whose mean age was 38.2 years old, with extra-genital endometriosis. RESULTS: Among the 60 cases of extra-genital endometriosis collected, bowel foci, 37 cases - 61,7% - were the most frequent; then we collected 13 (21.7%) skin, 7 (11.7%) urinary tract and 3 (5%) whole pelvis localizations. It's important to underline the finding of 2 aggressive malignant transformations. CONCLUSIONS: Extra-genital endometriosis should be considered as a cause of otherwise inexplicable abdominal pain in young women. Since imaging techniques lack in specificity, we propose explorative laparoscopy as a powerful diagnostic means. Moreover laparoscopy can be turned into a therapeutic act, also limiting the adherences issue, which is associated with this illness and would worsen with open surgery. Extra-genital endometriosis should be treated also to avoid rare, but possible, risk of cancerization.
Aim. Gallbladder carcinoma is an uncommon cancer with a poor prognosis. In the era of laparoscopic cholecistectomy for treatment of benign diseases incidental gallbladder carcinoma has dramatically increased and now constitutes the major way patients present with gallbladder cancer and allows to detect cancer at early stages with a better prognosis. In this single-center study we report our experience with gallbladder carcinoma incidentally diagnosed during or after laparoscopic colecistectomy performed for cholelithiasis. Methods. From January 2003 to December 2011 a total of 1193 patients underwent cholecistectomy at General Surgical Unit III of University of Bari. The patients were 458 males and 735 females, mean age was 52 years (range 19-91). In 6 of 1188 patients adenocarcinoma was present in the pathologic specimens (0,5%). Results. Of 1188 patients in whom laparoscopic cholecistectomy was attempted adenocarcinoma was diagnosed histopathologically in 6 cases (0,5%). There was no suspicion of malignancy to any of them. Intraoperatively, gallbladder wall appeared abnormal in one patients and frozen section analysis revealed adenocarcinoma. In the remaining 5 cases routine histopathological studies revealed the diagnosis of gallbladder carcinoma. One patient had T1 tumor, two had T2 and three had T3 tumor. Conclusions. In the present study the rate of incidental gallbladder carcinoma was 0,5%, according to the published English language literature. The risk factors widely related to the gallbladder cancer are advanced age and gallstones disease. The therapeutic approach to gallbladder cancer was applied according to the stage of tumor, but in our study this was possible only in two patients with T2 and T3 tumor since high risk and important comorbidities were the main causes for the refusal of 3 patient out of 5. Only the T1 patient underwent simple cholecystectomy. Similar to other reports in this single-center study the diagnosis of incidental gallbladder carcinoma was found to be of 0,5%, thus the diagnosis of gallbladder stones is an indication to the cholecystectomy.
Minimally invasive techniques have a definite role in the surgical treatment of several gastrointestinal tract cancers but there is still no widespread use of the laparoscopic approach for cancers of the head of the pancreas. The aim of this retrospective study is to review our experience from 2003 to 2013 in the management of pancreatic cancer with particular emphasis on the clinical application of minimally invasive techniques.
Left paraduodenal hernia is a rare congenital anomaly which arises from an error of rotation of the midgut; sometimes can be responsible for intestinal occlusion, that require surgery. In many cases of literature a prompt diagnosis and therapy reduced morbidity and mortality and almost all patients were discharged on 4th or 5th postoperative day (POD). We report a case of a 59 years old patient who underwent surgery for intestinal obstruction due to a massive left paraduodeneal hernia, that had a very long period (20 days) of postoperative ileus.
Recent studies show that interaction between LN (heterotrimeric protein formed by a3/b3/g2 chains) and cancer cells plays an important role in tumor invasion, also in colorectal cancer. The overall survival was significantly worse in patients with free peritoneal cancer cells(FPTCs): detection of FPTCs after curative surgery is a challenge, because could improve staging and prognosis. Peritoneal citology is the current standard procedure with very low sensivity. We aimed to study the expression of LN5 in the peritoneal lavage of colorectal cancer pts and in controls with semiquantitative reverse trancriptase-polymerase chain reaction (RT-PCR). LN-5 overexpression was evaluated observing PCR- products intensity at electrophoresis: high intensity is correlated to overexpression. Pre and post-operative peritoneal lavages of 30 pts with colorectal cancer (13M;17F), with median age of 69 (58-84), and of 10 controls, were analyzed by conventional cytology and a semiquantitative RT-PCR. No cancer pts showed pre/postoperative negative cytology and did not express LN-5. In cancer pts. cytology was positive in 2 pts in pre/postoperative lavage. LN-5 overexpression was observed in 56,6% preoperatively and in 76,6% postoperatively. LN-5 g 2 chain was most frequent chain. Our study suggests a relationship between LN-5 and FPTCs, as shown by the low expression of lamimine in controls. LN-5 could be a useful marker to identify a subgroup of early-stage patients at increased risk of recurrence; moreover, mortality seems to correlated to LAMB3 chain. The diagnostic accuracy could be improved by using a quantitative RT-PCR or western-blot and detecting serum laminine. Finally, to validate these findings a larger number of pts with follow-up study is required.
AIM: The authors reviewed their experience in surgical treatment of pancreatic cancer between 2003-2008. METHODS: Eighty two pancreatic cancer patients (median age 66.7 +/- 12.5) with obstructive jaundice were enrolled in our study: 36 (44%) had an endoscopic biliary stent; 46 patients (56%) were eligible for surgery: 14 received a curative surgery (pancreatoduodenal resection; 4 had a laparoscopic procedure) and 32 patients with non resectable tumor a palliative surgery: 18 had a gastro-jejunal with a biliary anastomosis (in 4 patients the hepatic-jejunal anastomosis was performed in laparoscopy), 6 had a gastro-jejunal anastomosis (2 laparoscopic procedure and 8 patients had only an explorative laparoscopy. RESULTS: The resectability rates was 17.1%. Median age in patients treated with endoscopic biliary stent was significantly higher than those underwent surgery (72.3 +/- 12.2 vs. 63.5 +/- 9.6; p < 0.05). Hospital length of stay in patients underwent radical surgery was significantly higher than those who received palliative surgery (18 +/- 6 vs. 10 +/- 5; p < 0.05). Morbility rate, including operative mortality of .3%, was 15.2%. CONCLUSIONS: Laparoscopy is largerly used in major oncologic surgery for several reasons: it minimized surgical manipulations and so post-operative complications. There is enough scientific evidence of low incidence of post-operative complications and long-term results compared to those achieved with traditional surgery.
