Postcholecystectomy syndrome: biliary-related complications

In Italy, about 100,000 cholecystectomies are carried out annually, the majority of them laparoscopically. Complications following cholecystectomy are common and increase morbidity and cost burden. Biliary damage (0.08-0.5%), bile leak (0.42-1.1%), retained common bile duct stones (0.8-5.7%), postcholecystectomy syndrome (10-15%), and postcholecystectomy diarrhea (5-12%) are a few of the most often occurring laparoscopic cholecystectomy consequences. In many instances, endoscopy can offer conclusive management and is crucial for the identification and treatment of biliary problems. Regarding the ideal treatment strategy for biliary problems, there is no universal agreement. A skilled interdisciplinary team should therefore approach biliary problems. The surgeon must be knowledgeable on how to handle these issues.

Flat patch mesh versus three-dimensional mesh (plug) for open umbilical or epigastric hernia repair. A retrospective study

INTRODUCTION

Hernia repair using prosthetic mesh materials has become the preferred method of repair, as the recurrence rates are much lower than with conventional repair techniques. The aim of this retrospective study was to compare open small- and medium-sized abdominal wall hernia repair with flat patch mesh versus three-dimensional mesh (plug) in terms of recurrence and complication rates.

METHODS

The medical records of 300 patients who underwent abdominal wall hernia repair using flat patch mesh versus three-dimensional mesh between January 2010 to December 2015 were reviewed. All patients were followed up after 1 month, 3 month and 1 year. The rate of recurrence, and short-term postoperative complications such as incidence of Surgical Site Infections (SSIs), hematoma and seroma were evaluated.

RESULTS

Short-term follow-up data were available for all patients. The first group was composed of 150 patients that were treated with a flat polypropylene mesh (68% presened umbilical hernia and 32% presented epigastric hernia). The second group was composed of 150 patients that were treated with a three-dimensional polypropylene mesh (60% presented umbilical hernia and 40% presented epigastric hernia). The majority of postoperative (1-month) complications were wound related, representing superficial SSI or seroma. Our results showed a statistically significant reduction of SSIs [3 (2%) vs 13 (8.6%); p = 0.038] and seroma [2 (1.3%) vs 12 (8%); p = 0.030] in the group of patients treated with plugs compared to flat-mesh group. There was no statistically significant difference in hernia recurrences.

DISCUSSION

Usage three-dimensional mesh for open small- and medium-sized umbilical or epigastric hernia repair represents a feasible and safe technique that significantly lowers the incidence of complications such as SSIs and seroma. Furthermore, compared to flat patch mesh, plugs displayed non-inferiority in terms recurrence. Further, well-designed clinical trials could be realized to investigate possible applications of plugs in treatment of small- and medium-sized umbilical and epigastric hernias.

Laparoscopic prosthetic repair of laparocele. A comparison of techniques and a review of the literature

Incisional hernia, or post-laparotomy hernia, is a defect in the abdominal wall, which can produce mechanical and systemic changes in both respiratory and splanchnic circulation. This pathology has an important impact on Health and Society, with an incidence ranging from 2% to 20%, stimulating the improvement or development of surgical techniques, to reduce discomfort and complications, e.g. imprisonment, strangulation and recurrences. The growing availability of prostheses, with greater resistance and lower risk of visceral adhesions, has improved the result and reduced relapses. Over the past 15 years, further improvements have been achieved, thanks to the greater use of laparoscopy, decreasing relapses and complications and improving patient comfort. In this regard, the Ventralight Echo PS prosthesis, introduced for the first time in 2013 and routinely used by our team, have shown encouraging results. In this work, a retrospective study aims to compare in different aspects two groups of patients, suffering from defects on the abdominal wall and undergoing reconstructive surgery with laparoscopic technique. It has been used simple prostheses for the first, whereas the Echo PS~ Positioning System with Ventralight - ST Mesh or Composix - L/P Mesh for the second group. In our experience, we conclude that the use of prostheses, such as the Ventralight Echo PS, in the treatment of incisional hernias, regardless of the location of the defect, is a valid and safe alternative to the use of non-self-expandable prostheses.

Symptomatic Parapelvic Cysts in Children: Anatomical and Histological Features, Diagnostic Pitfalls and Urological Management

Background: Symptomatic parapelvic cysts (PPC) are rare entities. Our objective is to highlight specific features of PPC to avoid a misdiagnosis of UPJ obstruction. Methods: We retrospectively reviewed the records of children managed between 2012–2017. Results: All four patients (18 months–8 years) presented with acute renal colic with a large intra-sinusal liquid mass (42–85 mm) on ultrasound, evoking a diagnosis of UPJ obstruction. On preoperative renal scintigraphy (n = 3) there was no dilatation of the renal pelvis and ipsilateral differential function was impaired in 2. Diagnosis of PPC was suspected preoperatively in three children (CT scan (n = 1); MRI (n = 2)) and made peri-operatively (n = 1). Preoperative retrograde pyelography (n = 3) and a further intraoperative retrograde pyelography with methylene blue (n = 1) did not identify communication with the cyst. No renal pelvis was identified in two patients. De-roofing of the cyst was curative in all cases at 5 years mean follow-up (no leakage, cyst recurrence or loss of function) and all 4 patients became asymptomatic after surgery. Histology demonstrated a single flat epithelial cell layer. Renal function normalized in one patient but remained impaired in the other. Conclusion: In case of symptoms of UPJ obstruction with a medial renal liquid mass on ultrasound, PPC should be considered when no dilatated pelvis on renal scan is identified. In such cases, a complementary imaging work-up is mandatory prior to surgery.

Neuropathic inguinal pain: neurectomy associated with open prosthetic hernioplasty for the prevention of post-operative pain

INTRODUCTION

Inguinal hernia is one of the most common surgical diseases in the world. Today, this disease is treated by surgical technique only. Among the late complications after surgery, the most frequent is the appearance of chronic post-operative pain after surgical treatment. The incidence of this complication is about 28% of patients undergoing hernioplasty suffering a varying degree of chronic pain, severe enough to interfere with normal daily activities.

OBJECTIVES

In this study we evaluated the onset of the neuropathic pain as a complication of inguinal prosthetic hernioplasty surgery.

METHODS

This is a prospective observational study run between September 2019 and August 2020. All patients, during the first visit conducted in an outpatient clinic, were recruited in a specific database. Subsequently, surgery was planned in election on one day surgery, patients were administered a specific questionnaire aiming at the identification of any pain and its exact location. The Inguinal Pain Questionnarie (IPQ) was used. During the surgical procedure the selective neurectomy of the 3 nerves has been documented, the entire population of patients has undergone a standardized surgical treatment. At the end of surgery, a follow-up was carried out administering two questionnaires (IPQ Short Form Modified and the IPQ Short Form Paresthesia Modified) concerning the possible chronic post-operative pain and the eventual paresthesia. The questionnaires were administered at first, third and sixth month from the date of surgery.

RESULTS

A total of 266 patients were screened from September 2019 to October 2020. Fiftyseven male patients were included in the study with a confirmed diagnosis of primary inguinal hernia. Clinical data, baseline characteristics and outcomes are described. Preoperatively, at the time of IPQ administration, 1.8% of patients had a pain score of 6, 10% of 5, 21% of 4, 31% of 3, 28% with a score of 2 and 7% of patients with a score of 1. In all cases the ileoinguinals and ileohypogastric nerves found were subjected to neurectomy, in 19% of cases also the genitofemoral nerve was subjected to surgical resection. At the end of the follow-up, the first questionnaire (IPQ Short Form Modified) results did show that, among the total of patients who had an open prosthetic hernioplasty with extensive nerves resection in the inguinal canal, 84% of them indicated a pain score equal to 0 (no pain) after 6 months of treatment and only 1.7% indicated a score equal to 4. Analyzing the second questionnaire on paresthesia (IPQ Short Form Paresthesia Modified), 79% of patients indicated a score equal to 0 by describing no paresthesia and no changes in sensitivity; 15.7% score 1; 3.5% score 2; 1.7% score 3.

CONCLUSIONS

Based on our experience and according to the modern literature, we would advise prophylactic total neurectomy of the inguinal canal nerves during prosthetic inguinal hernioplasty.

Intracorporeal versus extracorporeal anastomosis in laparoscopic right hemicolectomy A retrospective study and review of literature

INTRODUCTION

Several studies have suggested that intracorporeal anastomosis (IC) has advantages over extracorporeal anastomosis (EC) in laparoscopic right colectomy. Scientific evidence is lacking. The aim is to define the possible benefits of intracorporeal anastomosis compared with extracorporeal anastomosis in elective surgery.

METHODS

A single-centre retrospective study was performed. The primary endpoint was duration of hospital stay. Secondary outcomes included operative time, bowel recovery, conversion to open surgery and postoperative complications.

RESULTS

In the IC group mean hospital stay was 7,100 days, mean age was 70,5 years, mean operating time was 233 minutes and mean time to restoration of digestive function was 3,950 days. In the EC group mean hospital stay was 9,455 days, mean age was 72,55 years, mean operating time was 183 minutes, mean time to restoration of digestive function was 5,364 days.

CONCLUSION

This study shows many clinical outcomes advantages for the intracorporeal anastomosis technique in laparoscopic right colectomy. IA was associated with earlier bowel recovery, decreased hospital stay and fewer complications; operative time was shorter in EA KEY WORDS: Anastomosis, Colon cancer, Laparoscopy, Hemicolectomy, Retrospective.

Fournier's gangrene as a rare complication in patient with uncontrolled type 2 diabetes treated with surgical debridement: A case report and literature review

•

Fournier’s gangrene (FG) is a rare disease which usually affects men. It is characterized by progressive necrotizing fasciitis.

•

A 66-year-old man with uncontrolled type 2 diabetes, obesity with BMI 38, chronic kidney failure and chronic heart failure, reported the onset of symptoms about 14 days before his hospitalization, without consulting any doctor due to Covid-19 pandemic.

•

The combination therapy of surgical debridement and antibiotics infusion was effective.

Introduction

Fournier’s gangrene is a potentially fatal emergency condition, supported by an infection of perineal and perianal region, characterized by necrotizing fasciitis with a rapid spread to fascial planes. FG, usually due to compromised host, may be sustained by many microbial pathogens.

Case report

A 66-year-old man, with a history of uncontrolled type 2 diabetes, obesity with BMI 38, chronic kidney failure and chronic heart failure, was admitted to the Emergency Department with a large area of necrosis involving the perineal and perianal regions.

Discussion

Fournier’s gangrene is favoured by hypertension, obesity, chronic alcoholism, renal and heart failure. Generally, Fournier’s gangrene needs other procedures in addition to wound debridement such as colostomy, cystostomy, or orchiectomy.

Conclusion

We report a case of FG found as complication in a patient with uncontrolled type 2 diabetes, treated with effective combination therapy with surgical debridement and antibiotics infusion.

Dermatome Mapping Test in the analysis of anatomo-clinical correlations after inguinal hernia repair

Background

Nerve identification is recommended in inguinal hernia repair to reduce or avoid postoperative pain. The aim of this prospective observational study was to identify nerve prevalence and find a correlation between neuroanatomy and chronic neuropathic postoperative inguinal pain (CPIP) after 6 months.

Material

A total of 115 patients, who underwent inguinal hernia mesh repair (Lichtenstein tension-free mesh repair) between July 2018 and January 2019, were included in this prospective observational study. The mean age and BMI respectively resulted 64 years and 25.8 with minimal inverse distribution of BMI with respect to age. Most of the hernias were direct (59.1%) and of medium dimension (47.8%). Furthermore, these patients were undergoing Dermatome Mapping Test in preoperatively and postoperatively 6 months evaluation.

Results

Identification rates of the iliohypogastric (IH), ilioinguinal (II) and genitofemoral (GF) nerves were 72.2%, 82.6% and 48.7% respectively. In the analysis of nerve prevalence according to BMI, the IH was statistically significant higher in patients with BMI < 25 than BMI ≥ 25 P (< 0.05). After inguinal hernia mesh repair, 8 patients (6.9%) had chronic postoperative neuropathic inguinal pain after 6 months. The CPIP prevailed at II/GF dermatome. The relation between the identification/neurectomy of the II nerve and chronic postoperative inguinal pain after 6 months was not significant (P = 0.542).

Conclusion

The anatomy of inguinal nerve is very heterogeneous and for this reason an accurate knowledge of these variations is needed during the open mesh repair of inguinal hernias. The new results of our analysis is the statistically significant higher IH nerve prevalence in patients with BMI < 25; probably the identification of inguinal nerve is more complex in obese patients. In the chronic postoperative inguinal pain, the II nerve may have a predominant role in determining postoperative long-term symptoms. Dermatome Mapping Test in an easy and safe method for preoperative and postoperative 6 months evaluation of groin pain. The most important evidence of our analysis is that the prevalence of chronic pain is higher when the nerves were not identified.

Observational study: the use of the Ventralight Echo PS (positioning system) prosthesis in the treatment of incisional hernia

The treatment of incisional hernias, especially those that are multiple or recurring, has always represented important challenges for surgeons. An incisional hernia is a mechanical damage of the abdominal wall that can result in respiratory problems and alterations of splanchnic circulation, especially when in large size hernias. The increasing availability of prostheses with greater resistance Romato infections and tension, lightness, biocompatibility, and reduced visceral adhesions has improved outcomes and minimized relapses. It is still important, however, to carefully choose the type of prosthesis and surgical technique, whether laparotomic or laparoscopic, correlated to the positioning site of the prosthesis. In this observational study we report the results and outcomes of 50 patients surgically treated for incisional hernia in our hospital. The surgical technique used to repair the hernias was laparoscopic with the use of the Ventralight Echo PS. This prosthesis is equipped with a comfortable and innovative pneumatic system that facilitates its positioning during surgery. In our experience, it has brought undeniable advantages for the treatment of incisional hernias and for all patients with parietal defects who could benefit from laparoscopic treatment.

Intracesarean removal of two huge fibroids occupying the whole uterine fundus: a case report

Uterine fibroid is an estrogen-dependent mass growing during pregnancy. Caesarean myomectomy (CM) is a controversial procedure. A 35-year-old obese (106 Kg) patient gravida 2 para1 (caesarean section), undergoing caesarean section, had two myomas occupying the whole uterine fundus (104.2 mm and 50 mm respectively). Intracesarean myomectomy was carried out after extraction foetus (Apgar score: 9/10). Postoperative course was uneventful and patient was discharged after four days.

Anti-angiogenic effect of quercetin and its 8-methyl pentamethyl ether derivative in human microvascular endothelial cells

Angiogenesis is involved in many pathological states such as progression of tumours, retinopathy of prematurity and diabetic retinopathy. The latter is a more complex diabetic complication in which neurodegeneration plays a significant role and a leading cause of blindness. The vascular endothelial growth factor (VEGF) is a powerful pro‐angiogenic factor that acts through three tyrosine kinase receptors (VEGFR‐1, VEGFR‐2 and VEGFR‐3). In this work we studied the anti‐angiogenic effect of quercetin (Q) and some of its derivates in human microvascular endothelial cells, as a blood retinal barrier model, after stimulation with VEGF‐A. We found that a permethylated form of Q, namely 8MQPM, more than the simple Q, is a potent inhibitor of angiogenesis both in vitro and ex vivo. Our results showed that these compounds inhibited cell viability and migration and disrupted the formation of microvessels in rabbit aortic ring. The addition of Q and more significantly 8MQPM caused recoveries or completely re‐establish the transendothelial electrical resistance (TEER) to the control values and suppressed the activation of VEGFR2 downstream signalling molecules such as AKT, extracellular signal‐regulated kinase, and c‐Jun N‐terminal kinase. Taken together, these data suggest that 8MQPM might have an important role in the contrast of angiogenesis‐related diseases.

Neoplastic sigmoid-uterine fistula. An exceptional complication of large intestine cancer

Neoplastic sigmoid-uterine fistula is an extremely rare condition because the uterus is a thick and muscular organ. A 74-year-old woman was admitted to the First Aid Station suffering from abdominal pain and foul smelling vaginal discharge. Gynaecological examination showed fecal drainage from the cervical orifice, while the uterus was regular in size but very firm and painful. Ovaries and fallopian tubes were not palpable owing to abdominal tenderness. Ultrasounds reveled inhomogeneous thickening of uterine cavity, without detecting fistula. Contrast Medium CT (CMCT) showed Douglas' recto-uterine pouch occluded. The sigmoid wall was very thin exception a site where a fistula was suspected. At the surgery severe adhesions of the sigma-rectum with the posterior uterine wall were observed. After adhesiolysis, 18 cm colon-sigma-rectum was removed. Total hysterectomy with salpingooophorectomy was performed. Lymphadenectomy ended the procedure. Anatomical specimen confirmed sigmoid-uterine fistula. At histology a mildly differentiated adenocarcinoma of sigma-rectum was shown. Postoperative course was uneventful. Such a case of neoplastic sigmoiduterine fistula has not been reported so far.

Nuck canal cyst involving right femoral vein: management and therapy of a rare clinical case

We present a very rare case of a 49-year old woman suffering from Nuck canal cyst reaching and compressing femoral vein. Nuck canal cyst is very uncommon event because the pouch accompanying the gubernaculum during intrauterine descent of ovaries usually obliterates, whereas when it persists a cystic cavity containing citrine fluid develops. A gravid 0 para 0 49 old woman was admitted to Catania University Surgery Department owing to suspected lymphatic tumor compressing right femoral vein and causing groin pain with ipsilateral leg partial stasis. Patient believed right venous stasis was due to fibromatous uterus. Ultrasounds and computed tomography (CT) scan defined size (7.1 × 4.2 × 1.5 cm), structure (cystic) of mass and its relation with femoral vein, although they were not diriment for diagnosing its nature. Color Doppler detected circulatory function of compressed femoral vein. Surgery was challenging and Nuck cyst was removed after accurate separation from the right femoral venous walls. A case of Nuck cyst involving femoral vein has never been reported so far.

Oral Metronomic Vinorelbine in Advanced Non-small Cell Lung Cancer Patients Unfit for Chemotherapy

AIM

To explore the feasibility and activity of oral metronomic vinorelbine patients with advanced NSCLC not eligible to standard chemotherapy because of old age (≥70 years), and/or poor Eastern Cooperative Oncology Group performance status (≥2), and/or extensive brain or bone disease, and/or active comorbidities (≥2) requiring for pharmacological treatment.

PATIENTS AND METHODS

In a prospective phase II not randomized study, patients with stage IV NSCLC unfit to chemotherapy were treated with oral metronomic vinorelbine at 30 mg fixed dose three times a week until disease progression.

RESULTS

Fifty patients were treated, 19 (38%) in the first-line setting. Five patients (11%) experienced a grade 3 toxicity; no grade 4 toxicity occurred. Overall disease control rate was 32%, 44% and 26% in first and subsequent lines, respectively (p=0.39). Median OS and PFS were 7.3 months (95% confidence interval [CI]=4.7-10.0) and 2.7 months (95%CI=2.0-3.4), respectively.

CONCLUSION

These data support the activity and safety of metronomic vinorelbine in a relevant proportion of patients usually excluded from any specific treatment.

PAHs in seafood from the Mediterranean Sea: An exposure risk assessment

Seafood represent an important food source for human, and seafood quality is associated with marine environment quality. PAHs are one of the main organic environmental contaminants and they can be introduced into the body through different way (ingestion, inhalation, dermal absorption). We present data on bioaccumulation of the sixteen PAHs, defined priority by the U.S.- EPA, in Sardina pilchardus, Solea solea and Donax trunculus, three species caught in the Catania Gulf and highly consumed by the local population. The risk to develop chronic systemic and carcinogenic effects due to the consumption of these target species was evaluated through the EDI, THQ and CR. EDI derived from D. trunculus ingestion falls within the range calculated by the EFSA. The THQ is less than 1, and the CR calculated for the Benzo(a)Pyrene is at the limit of the ARL (1✕10^-5). EDI derived from S. pilchardus and S. solea ingestion are below the range calculated by the EFSA. The THQ is less than 1, and the CR is below the acceptable risk level. The contamination level found in local seafood determines a low risk to develop chronic systemic effects, but the cancer risk could be of health concern especially for high-frequency molluscs consumers.

Nasal metastasis as the first manifestation of a metachronous bilateral renal cell carcinoma

Renal cell carcinoma is one of the most common tumours to spread by extranodal metastases to the head and neck. Metastatic renal cell carcinoma to the head and neck area has been demonstrated mostly in the paranasal sinuses, parotid gland, the mandible, larynx and hypopharinx. Renal cell carcinoma should be excluded whenever a metastatic lesion is encountered in the head and neck area, even if the metastatic lesion is the first clinical presentation. The diagnosis of metastatic RCC should be suspected in any patient with even a remote history of renal cell carcinoma. We report a case of 79 year old woman with recurrent episodes of rhinorrhea, headache, hyposmia and monolateral right epistaxis, with a history of RCC. We describe RCC nasal metastases in a metachronous bilateral neoplasm, in which a second occult lesion debuted with a homolateral nasal metastases, ten years after left nephrectomy.

Single-Incision Laparoscopic Cholecystectomy: our experience and review of literature

AIM

After the revolution in the surgery of gallbladder stones represented by the laparoscopic cholecystectomy, we tried a new technique that further maximize the aesthetic results and that at the same time is of easy learning for young surgeons.

PATIENTS AND METHODS

From January 2011 to December 2012 we performed at our department 320 cholecystectomy: 27 in laparotomy and 293 in laparoscopy. Of these, 88 underwent to Single Incision Laparoscopic Surgery (SILS), namely the Single Incision Laparoscopic Cholecystectomy (SILC), in recruited patients aged between 19-65 years; 56 patients were females and 32 were males.

RESULTS

The laparoscopic cholecystectomy with the SILS methodology is a safe technique. Respect to multi-port Laparoscopic Cholecystectomy (LC), we have cosmetic advances. The pain is less in extraumbilical sites, and the major umbilical pain can be prevented by local anaesthesia. The times are slightly longer, especially at the beginning of training, but after a few of operations it is reduced to about one hour. We didn't found any other difference in vantage and advantage between the two technics, only a case of postoperative umbilical hernia in SILS.

CONCLUSION

We found the SILS a safe and effective technique for the cholecystectomy.

Colorectal cancer in aged patients. Toward the routine treatment through laparoscopic surgical approach

AIM

Colorectal cancer is one of the most common malignancies in general population. The incidence seems to be higher in older age. Surgery remains the treatment of choice and laparoscopic approach offers numerous benefits. We report our personal experience in elderly patients operated on for colorectal cancer with laparoscopic resection.

PATIENTS AND METHODS

From January 2003 to September 2013, out of 160 patients aged 65 years or older and operated with minimally invasive techniques, 30 cases affected by colorectal cancer and operated on with laparoscopic approach were analyzed in this study.

RESULTS

Male/female ratio was 1.35 and mean age 72 years. Constipation, weight loss, anemia and rectal bleeding were the most commonly reported symptoms. Lesions involved descending-sigmoid colon in 53% of cases, rectum in 37% and ascending colon in 10%. Among laparoscopic colo-rectal operations laparoscopic left colectomy was the most frequently performed, followed by right colectomy, abdominoperineal resection and Hartmann procedure. Operative times ranged from 3 to 5 hours depending on surgical procedure performed. Mean hospital stay was 6 days (range 4-9). Conversion to open approach occurred only in a case of laparoscopic right colectomy (3%) for uncontrolled bleeding. A single case of mortality was reported. In two cases (7%) anastomotic leakage was observed, conservatively treated in one patient and requiring reoperation in the other one.

CONCLUSIONS

Laparoscopic colorectal surgery is feasible and effective for malignancies in elderly population offering several advantages including immunologic and oncologic ones. However an experienced surgical team is essential in reducing risks and complications.

Hydronephrosis and utero-vaginal prolapse in postmenopausal women: management and treatment

INTRODUCTION

Pelvic organ prolapse is a multifactorial disease. Aim was to evaluate the effect of the whole surgical correction of pelvic floor on hydronephrosis due to severe prolapse.

PATIENTS AND METHODS

A retrospective case study on 250 patients presenting with severe uterovaginal prolapse was carried out.

RESULTS

Hydronephrosis was found in 32/234 (13.7 %). All patients underwent hysterectomy, vaginal apex axial suspension, posterior and anterior repair, vaginally. Prepubic TICT (Tension free Incontinence Cystocoele Treatment) was done in 38 cases (3 with hydronephrosis). Of the 32/234 (13.7 %) patients with hydronephrosis, 18/32 (56.25%) had complete resolution of hydronephrosis after treatment, 14/32 (43.75%) had a reduction of calico-pyelic dilatation, among them 8 patients had a second degree and 6 a first degree of hydronephrosis.

CONCLUSIONS

Vaginal-hysterectomy, axial apex suspension, anterior and posterior repair resulted in either complete resolution or improvement of hydronephrosis. Prepubic TICT did not interfere on mechanical obstruction and maintained postoperative continence in the event of occult Stress Urinary Incontinence (SUI).

Sentinel lymph node biopsy in breast cancer New indications and our experience

INTRODUCTION

Owing to complexity and difficulty regarding evaluation of all the regional lymph nodes, the Sentinel Lymph Node Biopsy (SLNB) has represented in recent years a suitable technique for setting lymph node status; it allows pathologists to focus on a small number of lymph nodes and stage patients with clinically negative lymph nodes; this sort of assessment leads surgeons to a correct approach; on the contrary, the presence of metastases makes advisable to perform Axillary Lymph Node Dissection (ALND).

MATERIALS AND METHODS

From September 2008 to December 2013, 142 patients suffering from breast cancer were enrolled. Mean age was 54 years (range 37-80), in 88 (62%) patients the lesion was localized to the right breast, while in the remaining 54 (38%) the disease was localized in the left breast. Also in 85 (60%) patients, the tumor involved the upper-outer quadrant, in 24 (17%) the lower external quadrant, in 19 (13%) the upper-inner quadrant and in the remaining 14 (10%) the inferior-internal quadrant.

RESULTS

There were neither intra nor post-operative complications. The all removed breast lesions were histologically malignant: 99 (70%) patients had a histological diagnosis of invasive ductal, 30 (21%) of invasive lobular, 9 (6%) ductal in situ and 4 (3%) of mixed invasive cancer. Sentinel Lymph Node (SLN) was always identified and it was extemporaneously positive in 62 cases (44%): 40 cases had macro-metastatic involvement whereas the remaining 22 cases had micro-metastases only. The definitive histological examination confirmed the presence of micro-metastases in 18 cases, while in 2 cases there was a supra-staging to macro-metastases and in other 2 a sub-staging of Isolated Tumor Cells (ITC). None of the patients with micro-metastatic SLN involvement developed recurrence within 24 months, whereas only one patient died after one year owing to at distance dissemination.

CONCLUSION

Lymph node status has increasingly been getting one of the most important prognostic factor. Consequently the bigger the tumor nodal involvement appears the worse the prognosis becomes. Our data confirm the main role of SLNB on managing surgical treatment of breast cancer.

Treatment of the pancreatic stump after DCP

OBJECTIVE

With improvement in methods, mortality after duodeno-cefalo pancreatectomy (DCP) has decreased to 5% even if complication rate is still high (30-50%). The pancreatic fistula still occurs in 25-50% of cases. Various methods of treating pancreatic stump have been proposed aimed to improve this rate.

PATIENTS AND METHODS

The AA, surgeons of suburban hospital, have performed in five years, 2009-2013, 12 DCP. The pancreatic anastomosis has been in all cases an end-to-end duct-to-mucosa pancreatic-jejunostomy.

RESULTS

The prevalence of fistula has been 33% (4 cases, 3 grade A and 1 grade B according with ISGPF score).

CONCLUSIONS

Soft pancreas and small size of pancreatic duct are recognized as the mayor factor of risk for pancreatic fistula. In these cases are usually preferred pancreatic-jejunostomy (PJ) and pancreatic-gastro-anastomosis (PG). Both techniques show advantages and disadvantages: some randomized and prospective studies have demonstrated the absence of significative differences respect to the prevalence of pancreatic fistulas. Whipple method has been the most often used reconstructive method: a single loop with bile-pancreatic anastomosis and gastro-pancreatic anastomosis in sequence. A careful evaluation of pancretic tissue and Wirsung size with the aim of choosing the most suitable technique and an accurate execution are the most effective methods to prevent pancreatic fistula,even considering particular setting as elderly patient or HIV infection.

Localized and systemic bacterial infections in necrotizing pancreatitis submitted to surgical necrosectomy or percutaneous drainage of necrotic secretions

Background

Infectious complications are observed in 40-70% of all patients with severe acute pancreatitis. Infections are associated with a significant increase in mortality rates.

Methods

We evaluated the prevalence and characteristics of pancreatic and systemic infections in 46 patients with necrotizing pancreatitis submitted to surgical procedures during their hospital stay as well as the impact of such infectious complications on patient clinical outcome. Samples for microbiological cultures were taken at hospital admission from blood and bile and 2 days after invasive procedure from blood, drainage fluid, bile and necrotic tissues.

Results

74% patients with necrotizing pancreatitis had a localized or systemic infection. At admission, 15% of subjects had positive blood cultures whereas 13% had evidence of bacterial growth from bile cultures. Two days after the invasive procedures for removal of necrotic materials and fluids, blood cultures became positive in 30% of patients in spite of antibiotic prophylaxis and bile cultures resulted positive in 22% of cases. Furthermore, bacterial growth from drainage fluids was found in 30% and from homogenized necrotic material in 44% of cases. As refers to bacterial isolates, all patients had a monomicrobial infection. Carbapenems were the drugs with the best sensitivity profile.

Mortality rate was significantly (p < 0.05) higher among patients with infection (17%) than subjects without infection (8%). Within the infected group, those subjects with evidence of systemic infection (positive blood cultures) developed more complications and demonstrated a higher (p < 0.05) mortality rate (28%) than those who had only a localized infection (10%).

Conclusions

Infectious complications significantly increase mortality in patients with necrotizing pancreatitis. In addition, subjects with systemic infections developed more complications and demonstrated a higher mortality rate in comparison with those having a localized infection. In our study, the sensitivity pattern of the isolated microorganisms suggests to consider carbapenems as the best option for empirical treatment in patients with necrotizing pancreatitis who develop a clear-cut evidence of systemic or localized bacterial infection.

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.

Non-AIDS-defining cancers among HIV-infected people

The natural history of HIV infection has been greatly changed by the introduction of highly active antiretroviral therapy (HAART). As a consequence of improved immune function, the incidence of AIDS-defining cancers (ADCs), such as Kaposi's sarcoma, non-Hodgkin's lymphoma (NHL) and invasive cervical cancer, has significantly declined. On the contrary, non-AIDS-defining cancers (NADCs), such as hepatocellular carcinoma, anal cancer, lung cancer, colorectal cancer and Hodgkin's lymphoma, have gradually emerged as a major fraction of the overall cancer burden. The reasons are still partially unknown. Some of the increased risk may be explained by a high prevalence of cancer risk factors, such as smoking, alcohol consumption, human papilloma virus (HPV) infection and HCV infection among HIV-infected people. The role of immunosuppression in the development of NADCs is controversial, as several studies have not found a clear-cut evidence of an association between the degree of immunosuppression and the development of NADCs. Analogously, the impact of HAART is still not well defined. Future research should focus on the etiology of NADCs, in order to shed light on the pathogenesis of cancer and ultimately to work for prevention; moreover, additional studies should evaluate the best therapeutic approaches to NADCs and the impact of cancer screening interventions among HIV-infected people, in an effort to diagnose cancer at an earlier stage.

Polyp of the cecum. Laparoscopic-assisted polypectomy

The Authors discuss on a laparoscopic-assisted approach for excision of a sessile villous adenomatous polyp of the cecum, unresectable by endoscopy. Because of the large implant of the polyp, endoscopic polypectomy was considered at high risk and a surgical laparoscopic procedure was scheduled for removal of the lesion. After right colon mobilization, an intraoperative endoscopy confirmed the location of th polyp in the posterior wall of the cecum, closed to the ileo-cecal valve. A small 10 cm laparotomy, through which the cecum was pulled out the abdominal cavity, was performed. Then, a minimal colotomy along the intestinal taenia was carried out to allow a safe and complete excision of the polyp. This laparoscopic approach differs from the other laparoscopic-assisted methods reported in the Literature since it provides at the same time the postoperative advantages associated with minimal access surgery and a safe oncological removal of the polyp with low risks of complications.

Incisional hernia in day surgery: our personal experience

Incisional hernia is one of the most common complications of laparotomy. Its repair with prosthesis has enabled a considerable improvement in the outcome, significantly reducing recurrences. This study analyses the results of open hernioplasty with mesh performed as a Day Surgery procedure in 42 patients between November 2008 and October 2010. The results were good, with low postoperative morbidity and recurrences (2.4%).

Iliohypogastric neurectomy in the prevention of postoperative pain following inguinal hernioplasty

Chronic postoperative pain is a common complication of inguinal hernia repair. An important Danish study revealed that 28.7% of patients undergoing hernioplasty suffered a varying degree of chronic pain, severe enough to interfere with normal daily activities in 11% of cases. The difficulty in treating this complication has led numerous surgeons to complete the surgical procedure ilioinguinal or iliohypogastric neurectomy. This method is proving effective in preventing the onset of chronic postoperative pain. We report the results obtained in patients undergoing neurectomy of the iliohypogastric nerve during anterior inguinal hernioplasty.

The role of laparoscopy and intraoperative ultrasound in the diagnosis and staging of lymphomas

Laparoscopic surgery plays today an important role in the diagnosis and staging of abdominal lymphomas; in fact it provides adequate lymph node sampling for histological typing and immunophenotyping. The mini-invasive procedure is safe and effective. Intra-operative ultrasound permits to study the parenchimal organs in addition to intra-abdominal lymph node and/or masses.

Laparoscopic surgery in acute small bowel obstruction: our experience

Small bowel obstruction (SBO) is a very common condition, in the vast majority of cases caused by post-operative adhesions. It often requires surgical treatment. Traditionally, this consisted of a laparotomy, but nowadays a laparoscopic approach is also possible. This study discusses 24 cases of SBO and compares them with literature data. Successful complete laparoscopic treatment was feasible in 9 patients, while conversion to laparoscopically-assisted surgery or laparotomy was required for the others.

Dynamic self-regulating prosthesis in inguinal hernia repair

Inguinal hernia repair is one of the most common surgical procedure performed in Western countries and it consumes a lot of healthcare resources. Several types of different mesh are now disposable and tension-free techniques represent the "golden standard". In our study, fifty male patients were operated on for inguinal hernia and a PAD (i.e., dynamic self-regulating prosthesis) used for the repair of the inguinal defect: this technique demonstrated to be safe, effective and easy to perform.

[Gastrointestinal stromal tumors: diagnosis and treatment. Our experience]

The incidence of GIST is estimated to be 1,5/100.000 per year; nevertheless they represent the most common mesenchimal tumours of gastrointestinal tract. Endoscopy, endoscopic ultrasonography and CT are the most used diagnostic tools. Complete surgical resection of localized GIST is the gold standard therapy, with possibility of laparoscopic approch in selected cases. Imatinib represents the recommended treatment of recurrent or metastatic disease. Diameter, mitotic count and surgical margins appear to be the main prognostic factors. In this paper we present ten cases of gastric or intestinal GIST and surgically treated.

Open tension-free Lichtenstein repair of inguinal hernia: use of fibrin glue versus sutures for mesh fixation

PURPOSE

To investigate pain and other complications following inguinal hernioplasty performed by the Lichtenstein technique with mesh fixation by fibrin glue or sutures.

METHODS

Five hundred and twenty patients were enrolled in this 12-month observational multicenter study and received either sutures or fibrin glue (Tissucol(®)/Tisseel(®)) based on the preference of the surgeon. Pain, numbness, discomfort, recurrence, and other complications were assessed postoperatively and at 1, 3, 6, and 12 months. Pain intensity was assessed by a visual analog scale (VAS; 0 [no pain] to 10 [worst pain]).

RESULTS

One hundred and seventy-one patients received sutures and 349 received fibrin glue. During the early postoperative phase, 87.4% of patients in the fibrin glue group and 76.6% of patients in the sutures group were complication-free (P = 0.001). Patients who received fibrin glue were also less likely to experience hematoma/ecchymosis than those in the suture group (both P = 0.001). The mean pain score was significantly lower in the fibrin group than the sutures group (2.5 vs. 3.2, P < 0.001). At 1 month, significantly fewer patients in the fibrin glue group reported pain, numbness, and discomfort compared with patients in the sutures group (all P < 0.05). Fibrin glue patients also experienced less intense pain (0.6 vs. 1.2; P = 0.001). By 3 months, the between-group differences had disappeared, except for numbness, which was more prevalent in the sutures group. By 12 months, very few patients reported complications.

CONCLUSIONS

Tissucol fibrin glue for mesh fixation in the Lichtenstein repair of inguinal hernia shows advantages over sutures, including lower incidence of complications such as pain, numbness, and discomfort, and should be considered as a first-line option for mesh fixation in hernioplasty.

[Repair of umbilical hernia in postmenopausal women]

The Authors report their personal experience on the employment of the dual-mesh in PTFE for the treatment of the umbilical hernias in postmenopausal women. The prosthetic repair versus the classic Mayo's technique finds justification for the biostructural deficits of the muscolofascial structures of the women in menopause, due to the reduction of the ovarian function and made worse from previous pregnancies. An evaluation of the trofism of the structures of the abdominal wall and the dimensions of the hernias is however indispensable in the choice of the prosthetic surgery. In our casuistry the reported morbidity due to immediate complications is absolutely negligible. Up to the present, although the follow-up is still short, we have not found recurrences.

[Fibrin sealant in tension free hernioplasty: our experience]

The aim of this study was to prove that it is possible to fix mesh sutureless with Tissucol in the Lichtenstein procedure. The mesh fixation with Tissucol was done in 28 patients. Respect the traditional Lichtenstein technique, which was done in the remaining 28 patients, the advantages of using Tissucol are: no surgical trauma, total mesh fixation, no pain, reduced morbidity and reduced costs. Furthermore it is a safe and reproducible method. The results are promising, even if the verification goes more carried out with consisting casuistics and longer follow-up.

[Gastrointestinal stromal tumors: report of three cases and review of the literature]

Gastrointestinal stromal tumours are the most common mesenchimal tumours of the gastrointestinal tract. Diagnosis of these tumours is difficult to establish, because symptoms are vague and traditional diagnostic tests are not specific. Natural history remains poorly defined and many criteria have been correlated with prognosis; for instance, some authors have found that GIST localization influences clinical behavior, that has not been confirmed by other authors; actually, tumour size, mitotic rate and complete resection seem to be the main prognostic factors. Surgical resection is the treatment of choice, with little efficacy reported for irradiation, conventional cytotoxic agents or both. Nevertheless, imatinib mesylate has recently demonstrated significant activity and tolerability in the treatment of malignant unresectable or metastatic GIST. Three cases of GIST, complicated by intestinal bleeding and intestinal obstruction respectively, are presented and a review of the literature is made.

[Day surgery for breast cancer in the elderly]

Early diagnosis of breast cancer and improvement of new technologies for identification and analysis of sentinel node allow more conservative surgical approaches, which guarantee both excellent local control and a good quality of life, also in elderly patients. We have studied a series of 28 women aged 70 years or older and affected by breast cancer. They underwent breast-preserving surgery either alone or in association with axillary lymphadenectomy and all of them had early discharge from hospital. This approach demonstrated to be safe and effective, so we may conclude that day-surgery treatment of breast cancer in these patients is possible in the majority of cases, is associated with low morbidity and is profitable for clinical, social and economic issues.

[Inguinal hernioplasty with PHS: our experience]

Three hundred patients underwent inguinal hernia repair from January 2003 to December 2004; 40 patients, randomly selected, received the PHS (Prolene Hernia System) mesh. Surgery was performed under local anesthesia in 80% of cases and under spinal anesthesia in the remaining 20%. There were 29 men and 11 women; mean age was 58,5 years (range 39-78). Postoperative pain was light and morbidity was low; all patients had early return to normal activities. Particularly, there were differences between the self-employed and the employees: the former began work again 2-4 days after surgery in 85% of cases, while the latter began after 15-20 days. Immediate complications were rare and always minor: they included seroma (1%) and ecchymosis (1%). Follow-up examinations did not show any recurrences.

[Stromal tumors of the small intestine: personal experience and review of the literature]

Malignant gastointestinal stromal tumors (M-GIST) are rare mesenchymal tumors that arise in the wall of the gastrointestinal (GI) tract. Small intestinal GIST account for approximately 35% of all GIST the diagnosis of these tumors is difficult to establish, because the symptoms are vague and non-specific and traditional endoscopy is commonly unsatisfactory. Because of the infrequent nature of malignant small bowel tumors, the natural history and factors affecting outcome remain poorly defined; stage at presentation and complete surgical resection seem to be the main prognostic factors. For these rare tumors, surgery remains the treatment of choice, with little efficacy reported for irradiation, chemiotherapy, or both. Two cases of GIST of the jejunum, complicated by intestinal bleeding and intestinal obstruction respectively, are presented and a review of the literature is made.

[Sentinel-node biopsy for breast cancer: our experience]

The method of sentinel lymphnode is a new procedure, suitable for the cases of early diagnosed breast cancers: identifying the first lymphatic station of the cancer, it can avoid the axillary lymphadenectomy in those women with primitive invasive and unifocal neoplasis of not more than 1.5 cm in diameter and without lymphnodal invasion. So it is reduced the frequency of postoperative troubles (sensitive and motor diseases, lymphedema). In our study, we have researched and identified, using radioactive isotopes, the sentinel lymphnode in 20 women suffering from subclinic breast cancer. We have obtained a percentage of 5% of false negatives. The optimal level of identification of the sentinel lymphnode and the good level of predictivity about the axillary lymphatic status, that we have obtained, represent a further confirmation of the surety and validity of this method.

[Bleeding gastric lymphoma: report of two cases]

We report two cases of bleeding gastric lymphoma. The stomach is the most common site of primary extranodal Non-Hodgkins Lymphomas. The best treatment for primary gastric lymphoma has not yet been defined. For many years the treatment of choice has been the gastric resection. Helicobacter pylori (H. pylori) has been associated with many gastric pathologies, including gastric lymphoma. Eradication of H. pylori is now considered essential for the treatment of this pathology, and usually consists of antibiotic therapy, combined with acid suppression by a proton pump inhibitor. This simple treatment in patients with low grade histology and tumor confined to the stomach can often obviate the need for surgical intervention. Surgery is a necessary treatment, independently of the grading and the staging of lymphoma, in the bleeding complication as the cases we showed.

[Surgical treatment of mucosal hemorrhoidal prolapse using a circular stapler]

We present a retrospective clinical study concerning our personal experience with the circular stapler in the treatment of hemorrhoids; the aim of this study was to evaluate the results of this surgical procedure, in terms of operative time, postoperative pain and rate of both short and long-term complications. Twenty-seven patients with grade 3 or 4 hemorrhoids, from January 1999 to June 2001, were included in the study. The main technical details of this procedure, requiring only a short learning period, are described and both short-term complications (such as severe postoperative pain, bleeding, urinary and fecal retention) and long-term ones (such as persistent or recurrent haemorrhoidal prolapse, anal stenosis) are analyzed. The reported results show that, in the presence of appropriate local anatomic conditions, this procedure is able to reduce the operative time, is almost painless and is characterized by low rate of complications.

[Dual mesh-plus for wall reconstruction in incisional and umbilical hernia in the aged]

The article reports the author's experience about the use of Gore-Tex Dual Mesh Biomaterial in large incisional hernia operations in patients over seventy. From January 1996 at present day we operated on 23 patients for treatment of abdominal wall defect. In all patients we used a Dual Mesh. Overall mortality was O. Morbility was 9.5%. Follow-up is too short for definitive considerations about the incidence of recurrences but our initial experience with this material encourages us to use it again for replacement of abdominal wall defects especially in the old patient.

[Ambulatory surgical treatment of primary hernia: our experience]

The authors report their personal experience (169 pz.) of the primary inguinal hernia repair in day surgery treated in local anaesthesia and by applying prosthesis according to latest "Tension-free and Suture-less" techniques. Results surely confirmed the validity of the method and the utility in creating centres concerning this type of surgery so that we are able to grant to the patient the best comfort that is to say a relevant reduction of the recurrence and a faster reintegration of patient's activities daily living.

[Surgical treatment of bleeding peptic lesions: our experience]

The authors report their experience on surgical treatment of peptic bleeding lesions. From January 1994 till April 1999 they observed and surgically treated 35 patients (mean age 65) suffering from bleeding gastroduodenal ulcer. Complications linked to surgical treatment had an incidence of 17.5%, while those ones linked to the patient's general conditions of 21%; mortality was 20%. Surgery has been gradually substituted by endoscopy which represent the principal examination for diagnosis of bleeding gastroduodenal ulcer with the aid of different hemostatic techniques, so that surgery has been relegated to the last place in uncontrollable bleeding treatment. Observed results, following those ones of other authors, show the unfavourable prognosis linked to patient's different conditions when surgeon operates.

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.

[Hernia repair with local anesthesia]

The authors report the results of their own personal experience with inguinal and femoral hernioplasties (424 cases) performed under loco-regional anaesthesia. This anaesthetic approach together with the use of prosthetic techniques (tension-free and suture-less) represent the "Gold Standard" in the surgical treatment of hernia. The absence of mortality, the remarkable reduction in terms of postoperative complications, days of hospitalization (one day surgery) represent outstanding advantages. The cooperation of the patient and the stress test at the end of the operation are further advantages of the proposed technique.

[The role of lymphadenectomy in colorectal neoplasms]

BACKGROUND

The role of lymphadenectomy in the treatment of large bowel cancer is still controversial, not only because it is deemed to be a basic element for a correct postoperative staging, but also because it brings about, according to some authors, an enhancement of survival and of "disease free survival" rates. The difficulty to collect case histories with homogeneous data and the impossibility to identify preoperatively with certainty the lymph nodes involved, makes it difficult to codify the most suitable surgical treatment, even if it is agreed at present, to extend lymph nodes dissection at least as far as Level II nodes. As a matter of fact, despite of slight enhancement of 5-year survival rate (6-8%), a significant increase in morbility occurs, as reported in the literature, particularly in terms of urological and neurological lesions. However, a few authors, perform systematically Level III dessection, reporting a 20% increase in survival.

METHODS

Our study, has been carried out on 84 patients affected by large bowel neoplasm and admitted to the Institute of Surgical Pathology I of "Vittorio Emanuele" Hospital of Catania between 1990-1995.

RESULTS

This study showed an involvement of Level I lymph nodes in 77% of patients and of Level II in 33%, while Level III nodes were affected only in 4.7% of cases.

CONCLUSIONS

On the basis of these data and of those reported in the literature, the conclusion is drawn that the most suitable and responsible attitude is, at present, to perform invariably Level I and Level II dissection, reserving the lymphadenectomy of Level III only to selected cases or when an involvement is documented pre and intraoperatively.

[Organizational and surgical-technical aspects of the service of abdominal hernioplasty]

The authors guided by the experience matured from 1/01/94 to 30/06/97 (435 abdominal hernioplasties performed, mainly inguinal and femoral) illustrate the organizational formalities and the technical aspects of a Hernia Surgery Service. In particular, they highlight the advantages of the routine use of local anaesthesia and of tension-free techniques, carried out on a day surgery rule (immediate rehabilitation, greater facilitation to elective surgery, access to the elderly at high anaesthetic risk). Eventually, they emphasize the remarkable reduction of sanitary costs and the outstanding social, practical and didactic value of such Hernia Centers.

[Does there exist a current indication for myotomy in diverticular disease of the colon?]

Thanks to advances of gastroenterological and dietary regimen of patient with more complicated diverticular disease of the colon, the surgical indications to myotomy are nowadays very low, if not more at all. The insurgence of complications is naturally a precise indication to demolitive surgery actually with low postoperative morbidity and mortality.
