Pancreatoduodenectomy currently represents the treatment of choice for resectable pancreatic and periampullary malignant tumours, symptomatic chronic pancreatitis, duodenal cystic dystrophy, large adenomas, diverticula and benign periampullary tumours. Pancreato-jejunostomy failure remains the main complication following pancreatoduodenectomy, even leading to death. To improve the safety of this anastomosis, a modified technique of pancreato-jejunal anastomosis with posterior double-layer suture and Wirsung duct evagination is proposed. We report our experience in eight consecutive patients (4 females, 4 males; average age 66, range 57-74) undergoing Traverso-Longmire pylorus-preserving pancreatoduodenectomy using Wirsung duct evagination and posterior double-layer suture technique. There was no mortality; the post-operative recovery was uneventful with no pancreatic anastomotic leakage. The mean post-operative stay was 15 days (range 12-19). This proposed procedure could be considered an additional opportunity in the performance of a pancreato-enteric anastomosis, yielding good results and preserving from post-operative pancreatic ductal obstruction
Background: We sought to determine the efficacy of sutures, human fibrin glue and N-butyl-2-cyanoacrylate for mesh fixation in patients undergoing the plug and mesh procedure for groin hernia. Methods: A total of 156 patients with 167 inguinal hernias (11 bilateral) underwent a plug and mesh procedure and were randomly assigned to received either sutures (n = 59 hernias), human fibrin glue (n = 52) or N-butyl-2-cyanoacrylate (n = 56) for mesh fixation. Results: The overall morbidity rate was 38.98% in the suture group, 9.62% in the fibrin glue group and 10.71% in the N-butyl-2-cyanoacrylate group (suture v. fibrin glue, p < 0.001; suture v. N-butyl-2-cyanoacrylate, p < 0.001). There was no significant difference in morbidity between the fibrin glue and N-butyl-2-cyanoacrylate groups. Overall, short-term morbidity was significantly higher in the suture group (27.12%) than in the fibrin glue (9.62%, p = 0.01) or N-butyl-2-cyanoacrylate (8.93%, p = 0.004) groups, but there was no significant difference between the fibrin glue and N-butyl-2cyanoacrylate groups. There was no significant difference between the groups in terms of mean postoperative stay (32.6 h in the suture group v. 30.8 h in the fibrin glue group v. 32.0 h in the N-butyl-2-cyanoacrylate group) or mean time to return to work (20.4 d in the suture group v. 20.3 d in the fibrin glue group v. 19.8 d in the N-butyl-2-cyanoacrylate group). Overall, long-term morbidity was significantly higher in the suture group (11.86%) than in the fibrin glue (0%, p = 0.001) or N-butyl-2cyanoacrylate (1.78%, p = 0.03) groups. There was no recurrence in any of the groups. Two cases (3.39%) of chronic groin pain were reported in patients in the suture group. A sensation of extraneous body was reported in 5 (8.47%) patients who received sutures and in 1 (1.78%) patient in the N-butyl-2-cyanoacrylate group; there were no reported cases in the fibrin glue group (suture v. fibrin glue, p = 0.01; suture v. N-butyl-2-cyanoacrylate, p = 0.03; fibrin glue v. N-butyl-2-cyanoacrylate, p = 0.30). Conclusion: The use of human fibrin glue or N-butyl-2-cyanoacrylate is better tolerated than sutures in tension-free inguinal open repair using the plug and mesh technique in terms of overall immediate results, and there is a better trend in the long-term data.
Background: The prevalence of thyroid disease in patients with cardiac disease can be as high as 11.2%. Combined thyroid and cardiovascular surgery has rarely been reported. Methods: Ten patients (6 female, 4 male, age range 51-73 years) had total thyroidectomy and cardiac surgery in the same procedure in our surgical department. Six patients had coronary artery disease; four patients had valvulopathy. The thyroid goiter was retrosternal in 6 patients. Results: Mean stay in the intensive care unit was 46.4 hours; the postoperative course was complicated by transient right laryngeal nerve palsy in one case and by transient hypocalcemia in the patients in whom a parathyroid autotransplantation was performed (n = 3). There was one case of hemodynamic compromise needing vasoactive drug support; the mean hospital stay was 8.4 days. Conclusions: Our experience and our review of the literature suggest that a single-stage procedure is safe and feasible and must be preferred to different operations as it has an acceptable peri-operative and anesthesiological risk.
To compare the outcome in patients with cervical goiters and cervicomediastinal goiters (CMGs) undergoing total thyroidectomy using the cervical or extracervical approach. This was a retrospective study conducted at six academic departments of general surgery and one endocrine-surgical unit in Italy. The study population consisted of 19,662 patients undergoing total thyroidectomy between 1999 and 2008, of whom 18,607 had cervical goiter (group A) and 1055 had CMG treated using a cervical approach (group B, n = 986) or manubriotomy (group C, n = 69). The main parameters of interest were symptoms, gender, age, operative time, duration of drain, length of hospital stay, malignancy and outcome. A split-sternal approach was required in 6.5% of cases of CMG. Malignancy was significantly more frequent in group B (22.4%) and group C (36.2%) versus group A (10.4%; both P < .001), and in group C versus group B (P = .009). Overall morbidity was significantly higher in groups B + C (35%), B (34.4%) and C (53.5%) versus group A (23.7%; P < .001). Statistically significant increases for group B + C versus group A were observed for transient hypocalcemia, permanent hypocalcemia, transient recurrent laryngeal nerve (RLN) palsies, permanent RLN palsies, phrenic nerve palsy, seroma/hematoma, and complications classified as other. With the exception of transient bilateral RLN palsy, all of these significant differences between group B + C versus group A were also observed for group B versus group A. Symptoms, malignancy, overall morbidity, hypoparathyroidism, RLN palsy and hematoma are increased in cases of substernal goiter.
UNLABELLED: ABSTRACT: BACKGROUND: Acute respiratory failure due to thyroid compression or invasion of the tracheal lumen is a surgical emergency requiring urgent management. The aim of this paper is to describe a series of six patients treated successfully in the emergency setting with total thyroidectomy due to ingravescent dyspnoea and asphyxia, as well as review related data reported in literature. METHODS: During 2005-2010, of 919 patients treated by total thyroidectomy at our Academic Hospital, 6 (0.7%; 4 females and 2 men, mean age: 68.7 years, range 42-81 years) were treated in emergency. All the emergency operations were performed for life-threatening respiratory distress. The clinical picture at admission, clinical features, type of surgery, outcomes and complications are described. Mean duration of surgery was 146 minutes (range: 53-260). RESULTS: In 3/6 (50%) a manubriotomy was necessary due to the extension of the mass into the upper mediastinum. In all cases total thyroidectomy was performed. In one case (16.7%) a parathyroid gland transplantation and in another one (16.7%) a tracheotomy was necessary due to a condition of tracheomalacia. Mean post-operative hospital stay was 6.5 days (range: 2-10 days). Histology revealed malignancy in 4/6 cases (66.7%), showing 3 primitive, and 1 secondary tumors. Morbidity consisted of 1 transient recurrent laryngeal palsy, 3 transient postoperative hypoparathyroidism, and 4 pleural effusions, treated by medical therapy in 3 and by drains in one. There was no mortality. CONCLUSION: On the basis of our experience and of literature review, we strongly advocate elective surgery for patients with thyroid disease at the first signs of tracheal compression. When an acute airway distress appears, an emergency life-threatening total thyroidectomy is recommended in a high-volume centre.
Hypercalcaemic crisis is an uncommon and potentially life-threatening manifestation of primary hyperparathyroidism, and it is associated with rapid deterioration of the central nervous system, and cardiac, gastrointestinal, and renal function. We present the case of a 76 year-old man in a sudden coma due to hypercalcaemic crisis as a first manifestation of primary hyperparathyroidism. At first, the patient was treated conservatively, his mental status gradually improved in the next three days. On the ninth day after the initiation of therapy, a minimally invasive radio-guided parathyroidectomy was performed. Histologically, the tumour consisted of densely arranged chief cells immunohistochemically positive for PTH antigens, suggesting adenoma. Calcaemia level and PTH were normalised in the immediate postoperative period. A systematic review was performed by consulting PubMed MEDLINE for publications from 1958 to 2011. This review found a total of 499 reported cases of hypercalcaemic crisis due to primary hyperparathyroidism. Manifestations are neurological alterations, and cardiac, renal and gastrointestinal dysfunctions associated with markedly elevated serum calcium and parathyroid hormone levels. The most frequent histology is the parathyroid adenoma. In untreated cases, mortality is 100%. Despite advances in its management, the mortality rate is still 93.5% in patients treated only conservatively. Medical therapy followed by expeditious parathyroidectomy should be considered as the treatment of choice for patients affected by hypercalcaemic crisis due to a primary hyperparathyroidism.
Mirizzi's syndrome (MS) is a rare complication of the inveterate biliary lithiasis. Diagnostic and therapeutic standardization is still missing, especially since laparoscopic cholecystectomy has become the gold standard approach for symptomatic cholelithiasis. Our study is a retrospective analysis based on a case-series. It considered 370 cholecystectomies performed from 2006 to 2011. We selected 11 patients affected by MS (2.97%). We divided them according to Csendes' classification. Endoscopic Retrograde Cholangio-Pancreatography (ERCP) was used for biliary drainage when the patient suffered jaundice and/or cholangitis and, preoperatively, to confirm the suspicion of MS obtained through Magnetic Resonance Cholangio-Pancreatography (MRCP). We found it useful to exploit nasobiliary drainage (NBD) for intra-operative check of the biliary tree. In all 5 patients of the type 1 group MS was discovered intraoperatively and treated with Laparoscopic Sub-total Cholecystectomy (LSC). One patient suffered from biliary leakage, solved with NBD positioning. The type 2 group was made up of 2 women and 1 man. All of them were preoperatively submitted to ERCP and NBD positioning. Two underwent LSC and one was converted to laparotomy. The type 3 was represented by a 63-year-old woman suffering from recurrent cholangitis. She was submitted to MRCP, ERCP and then underwent LSC. The 2 patients affected by type 4 underwent open biliary reconstruction. In conclusion, every attempt should be made to identify MS prior to LCS since it will allow NBD insertion by ERCP. Once LCS is initiated, if MS is identified intra-operatively, we can provide the most practical surgical options.
Pancreatitis is a diffuse systemic immuno-inflammatory response to a localized process of auto-digestion within the pancreatic gland, caused by premature activation of proteolytic digestive enzymes. According to the ATLANTA criteria (1992) we recognized a mild and a severe acute pancreatitis (SAP ) . Mortality rate in SAP account up to the 20 percent and most complications and deaths are due to an inflammatory immune response to pancreatic necrosis and/or infection. Patients affected by SAP rapidly incur accelerated catabolism and thus nutritional support is essential, especially in the earliest period of the disease. Recent observations show that the route of nutritional support may also affect disease severity and its course. In this view several important questions about nutritional support need to be addressed : indication , timing, enteral vs parenteral and composition . With this review we analyze the state-of-the-art and we present a decisional flow chart to better manage the nutritional support in SAP.
The parathyroid hormone-related peptide (PTHrP) has been shown to be the major pathogenic factor to humoral hypercalcemia of malignancy (HHM). The presence of PTHrP in many normal tissues and in normal or abnormal parathyroids has been described in literature and its role has been investigated. PTHrP release from parathyroid cells into the extracellular space has been demonstrated to depend on the extracellular calcium concentration. The hormone binds to PTH type 1 Receptor (PTH1R) with a high affinity, as well as parathyroid hormone (PTH). These hormones' amino-terminal (1-34) peptide fragments are considered sufficient to achieve efficient receptor activation and action on mineral ion homeostasis. Generally, diagnosis of primary hyperparathyroidism (PHPT) is based on hypercalcaemia and elevated levels of PTH. The advent of intact-PTH immunoradiometric assay allowed us to distinguish PHPT from non-parathyroid-dependent hypercalcaemia, but the presentation of normal PTH level and hypercalcaemia due to a parathyroid adenoma is possible. The aim of the study is to identify the relationship between the production of PTHrP without malignancy and the diagnosis of PHPT by a systematic review.
The aim of this retrospective multicenter study was to verify whether the substernal goiter and the type of surgical access could be risk factors for recurrent laryngeal nerve palsy during total thyroidectomy. Between 1999-2008, 14,993 patients underwent total thyroidectomy. Patients were divided into three groups: group A (control; n=14.200, 94.7%), cervical goiters treated through collar incision; group B (n=743, 5.0%) substernal goiters treated by cervical approach; group C (n=50, 0.3%) in which a manubriotomy was performed. Transient and permanent unilateral palsy occurred significantly more frequently in B+C vs. A (P≤.001) and in B vs. A (P≤.001). Transient bilateral palsy was significantly more frequent in B+C vs. A (P≤.043) and in C vs. A (P≤.016). Permanent bilateral palsy was significantly more frequent in B+C vs. A (P≤.041), and in B vs. A (P≤.037). Extension of the goiter into the mediastinum was associated to increased risk of recurrent nerve palsy during total thyroidectomy.
Pancreatoduodenectomy is an exceptional procedure that requires an extensive dissection of the supramesocolic region extended to the first jejunal limb. Lymphadenectomy, required for cancer, increases the dissection surface. The extensive preparation of the area is traditionally conducted with bipolar or monopolar instruments, while clips, ligatures, and sutures are used for haemostasis. LigaSure™ vessel sealing (LSVS; Valleylab, Boulder, CO) is a technology that obtains vessel closure by using the body’s own collagen and elastin to create a permanent fusion zone. This is obtained by a combination of forceps pressure and radio frequency. This effect has been improved by the introduction of the ForceTriad™ (Valleylab, Boulder, CO) energy platform, controlled by TissueFect™ (Valleylab, Boulder, CO) sensing technology. With this device, the surgeon is able to fuse vessels up to 7 mm, lymphatics, tissue bundles, and pulmonary vasculature in a fast-seal cycle of almost 4 seconds. In our daily practice of open surgery we observe a rapid improvement of abdominal drainage output with a drastic reduction of protein loss. Its practical significance is, in our opinion, that we obtain a rapid recovery of normal serum protein levels with a low number of blood/plasma sac transfusions and a real improvement of anastomosis healing. Moreover, the efficacy and the speed of work of the device allow us to reduce the operating time significantly but safely. We performed a retrospective analysis of the data of 20 pancreatic resections conducted both with traditional dissection and with the Liga- Sure Impact device with ForceTriad platform in order to verify whether observed data were real. Our clinical results show that the use of the LigaSure Impact device with ForceTriad energy platform is really useful in open surgery to save operating time, number of postoperative days, and hemoderivate administration.
BACKGROUND: Appendicitis is the most common cause of acute abdomen, and appendectomy is the most frequent surgical procedure performed in the world. In recent times, laparoscopic appendectomy has been gaining increasing consensus, although comparison with traditional open surgery is still debated. Recent reports seem to agree in recognizing laparoscopy as the favourable approach in cases of non-complicated appendicitis, in women and in obese patients. The use of a linear stapler to close the appendiceal stump also seems to guarantee a dramatic decrease of complications and this observation could be the rationale for considering the laparoscopic approach to also be safe in complicated appendicitis. In these cases, dissection of the mesoappendix and isolation of the viscum could be very difficult and could cause complications. By proposing this technique using a laparoscopic approach, we try to permit a simple and safe section of the appendix leaving the detachment from vessels and from the neighbourhood to a second moment. MATERIALS AND METHODS: We report our initial experience including the first 50 cases and proposing our personal technique of laparoscopic appendectomy. RESULTS AND CONCLUSION: We recorded only one intraoperative haemorrhage, one bladder perforation due to trocar insertion and no conversion. Our goal is to standardize and simplify the laparoscopic approach in order to give any surgeon, even non-expert ones, a simple way to remove the viscum especially in complicated pictures.
INTRODUCTION: Barbed sutures are routinely used for laparotomy, peritoneal and mesenteric closure, but few studies have reported their use for intestinal anastomosis. We proposed their use for totally hand-sewn anastomosis during laparoscopic gastric bypass secured at the end of the suture with an absorbable clip. MATERIALS AND METHOD: Two totally hand-sewn single-layer extramucosal running sutures were performed for side-to-side gastrojejunal and jejuno-jejunal anastomosis during laparoscopic gastric bypass. Each run (anterior and posterior layer) was locked at the end by an absorbable poly-p-dioxanone suture clip. RESULTS: A total of 96 hand-sewn anastomoses were performed. A total of two leaks occurred originating from the jejunaljejunal anastomosis. No cases of leakage from gastrojejunostomy were recorded. Two stenoses of the gastrojejunal anastomosis were recorded. They were successfully treated with three sessions of endoscopic balloon dilatation. No bleeding occurred. CONCLUSION: In our experience, the suture-related complication rate is comparable with the data reported in the literature. Further studies are needed to address the safety and efficacy of the self-maintained suture in digestive surgery.
