Laparoscopic giant hiatal hernia repair with absorbable mesh.

Background: The best operative approach to large hiatal hernias still remains controversial between suture cruroplasty and prosthetic hiatal herniorrhaphy. This study aims at analysing results from a single institution in Italy in terms of subjective and objective outcomes. Methods: Retrospectively collected data of all patients that underwent laparoscopic hiatal hernia repair since 2011 were considered. Sixty-five patients were included overall; 17 of them fit the criteria of large hiatal hernia. Follow-up (FU) was assessed by visit, questionnaires and X-ray imaging. Results: No major complications occurred in the post-operative course. No patient was lost during the FU period. Out of all the patients included, 13 agreed to have an X-ray with water-soluble contrast. The questionnaires showed a 76.5% rate of satisfaction (13 patients), and the recurrence rate demonstrated by radiology was 29.4% (five patients). There were no major mesh-related complications. Conclusion: The best operative approach for large hiatal hernias remains far from standardised: There is a lack of evidence on the use of a mesh for this kind of surgery as well as substantial controversy over the definition of what a giant hiatal hernia is. Nevertheless, the results from this study and the main studies in the literature seem to be encouraging in improving giant hiatal hernia repair outcomes.

The Role of DAMPS in Burns and Hemorrhagic Shock Immune Response: Pathophysiology and Clinical Issues. Review.

Severe or major burns induce a pathophysiological, immune, and inflammatory response that can persist for a long time and affect morbidity and mortality. Severe burns are followed by a "hypermetabolic response", an inflammatory process that can be extensive and become uncontrolled, leading to a generalized catabolic state and delayed healing. Catabolism causes the upregulation of inflammatory cells and innate immune markers in various organs, which may lead to multiorgan failure and death. Burns activate immune cells and cytokine production regulated by damage-associated molecular patterns (DAMPs). Trauma has similar injury-related immune responses, whereby DAMPs are massively released in musculoskeletal injuries and elicit widespread systemic inflammation. Hemorrhagic shock is the main cause of death in trauma. It is hypovolemic, and the consequence of volume loss and the speed of blood loss manifest immediately after injury. In burns, the shock becomes evident within the first 24 h and is hypovolemic-distributive due to the severely compromised regulation of tissue perfusion and oxygen delivery caused by capillary leakage, whereby fluids shift from the intravascular to the interstitial space. In this review, we compare the pathophysiological responses to burns and trauma including their associated clinical patterns.

Chevrel technique for ventral incisional hernia. Is it still an effective procedure?

BACKGROUND: Incisional hernia still represents the most frequent late complication of abdominal surgery. After a direct repair, in literature is reported a recurrence rate ranging from 31 to 49%, meanwhile after a prosthetic repair such values were much lower, with a recurrence rate up to 10%. The sites of prosthetic placement in the abdominal wall are premusculo-aponeurotic (onlay, or Chevrel technique), retromuscular-prefascial and preperitoneal (Rives technique, Stoppa technique), whereas intraperitoneal insertion can be done with open or laparoscopic surgery. The aim of this study was to evaluate the immediate and late postoperative results in patients treated with a Chevrel technique for ventral incisional hernia. METHODS: A retrospective review was conducted on the medical records of patients undergoing ventral hernia repair between January 2008 and December 2018 at the Emergency Surgery Unit of the Careggi University Hospital in Florence. RESULTS: Between January 2008 and December 2018 at the Emergency Surgery Unit of the Careggi University Hospital in Florence, 461 patients (245 male, 216 female) with a mean age of 61,52 years were submitted to ventral incisional hernia repair with a Chevrel technique. The mean operatory time was 95.29 min (±50.48) and in 72 patients (15.61%) human fibrin glue was vaporized under the mesh using a spray device. Mean postoperative hospital stay was 5 days and all drain tubes were removed after 7.1 days as mean (±4.3). No intraoperative mortality nor postoperative mortality was reported. In our experience the Chevrel technique for ventral incisional hernia show a recurrence rate (3.2%). Parietal complications observed were seroma in 7.1% of patients, hematoma in 4.7%, localized skin necrosis in 5.2%, surgical site infection in 6.7%, data comparable with the results reported in the other studies. CONCLUSIONS: Most of the objections to the Chevrel procedure focus on the parietal complications and risk of infection. Chevrel procedure cannot be considered an obsolete intervention, in our series, results were very satisfactory in both immediate and late follow-up; moreover this technique is safe and easy to perform.

Urgent cholecystectomy in patient with left-sided gallbladder Case report and review of the literature.

INTRODUCTION: Sinistroposition of the gallbladder, or true left-sided gallbladder (LSG) without situs viscerum inversus, is a rare congenital anatomical variant where the gallbladder is located to the left of round/falciform ligament. It can be associated with anomalies of the biliary tree, portal system and hepatic vascularization. The surgical management of a LSG could be challenging even for an experienced operator, being usually an incidental intraoperative finding. CASE REPORT: A 72 years old woman was admitted to our emergency department because of acute cholecystitis. There were no pre-operative indications of sinistroposition of the gallbladder and its aberrant position was discovered during the explorative laparoscopy; because of the unusual anatomy and chronic flogosis, the laparoscopic approach was converted to open surgery. The patient underwent a successful intervention and was discharged after 4 days without complications. Her family history revealed a daughter with biliary atresia. DISCUSSION: LSG could remain undetected at preoperative imaging, but today, with advances in diagnostic imaging, the report of this condition has increased. Several hypothesis suggest the presence of an underlying embriologic mechanism for LSG and its associated anomalies, but its etiology is still unknown. The association with the daughter's biliary atresia makes reasonable a possible genetic correlation with this condition. CONCLUSIONS: In case of LSG, laparoscopic cholecystectomy could be feasible and safe, but with an increased risk of injury to the major biliary structures, mostly in case of severe and chronic inflammation of the gallbladder. Surgeons have to know this variant because of its associated hepatic anomalies. KEY WORDS: Cholecystectomy, Emergency Surgery, Left-Sided-Gallbladder.

Open abdomen management for massive intestinal infarction due to acute splanchnic venous thrombosis in a patient with protein S deficiency. A case report.

INTRODUCTION: Acute mesenteric ischemia (AMI) refers to the sudden onset of intestinal hypoperfusion that can also result from splanchnic venous occlusion. The portomesenteric venous system (PMVS) is an unusual site of thrombosis in patients with protein S deficiency and its obstruction is a rare cause of AMI. Aim of this report is to illustrate a successful strategy in a case of massive small bowel infarction managed with an open abdomen (OA) approach. CASE PRESENTATION: A 64 year-old woman presented to the emergency department with acute abdominal pain, rectal bleeding, diarrhea and vomiting. Contrast-enhanced computed tomography (CECT) showed small bowel ischemia and the complete occlusion of all the PMVS branches. Surgery was performed with an OA approach and anticoagulation was immediately begun. Further workup revealed isolated protein S deficiency and history of atrophic gastritis. Thromboprophylaxis with warfarin was started on discharge and no recurrence of thrombotic events was recorded during the one-year follow-up. DISCUSSION: PMVS thrombosis related to protein S deficiency is a rare condition that can rapidly lead to an acute abdomen. CECT is the gold standard, because it detects splanchnic thrombosis and its possible complications, like bowel ischemia. In case of surgery, a planned second-look operation is the best strategy to assess bowel viability and possible ischemic progression. CONCLUSIONS: OA management plays a fundamental role in case of resection for bowel ischemia. Patients with thrombosis at an uncommon site should be further investigated for prothrombotic states.

Laparosacopic management with combination of fatty meal and methylen-blu for chylous leak after a left para-aortic paraganglioma excision.

We report a case of chylous leak recognized post-operatively after abdominal surgery for left para-aortic paraganglioma in a young female with a history of open botallo's duct. Conservative measures failed to control the leak and the patient is not eligible for sclerotisation. Laparoscopic exploration with intralipidand methylen blue injection through an orogastric tube revealed the leaking area near the superior mesenteric vein behind the Traitz, and this was ligated with non-asorbable suture and placement of acrylic glue. The patient was discharged the 7th post-operative day after removal of the drainage which appeared to supply <100 cc of serum material. Outpatient control was successful and the patient is actually in good conditions.

The Role of Laparoscopy in the Management of a Diagnostic Dilemma: Jejunal Ectopic Pancreas Developing into Jejunojejunal Intussusception.

Ectopic pancreas (EP) is a rare congenital anomaly defined as the presence of pancreatic tissue in topographic anomaly. It is usually silent but it may become clinically evident when complicated by acute conditions. The development of laparoscopic surgery has changed the way to manage such conditions, especially in the setting of emergency surgery, thanks to its diagnostic and therapeutic role with excellent results. We decided to perform an emergency diagnostic exploratory laparoscopy in a 29-year-old man with an acute abdomen and nonspecific radiological images for intestinal occlusion. A jejunojejunal intussusception was found, caused by a mass. We decided to carry out minilaparotomy to perform a resection of the affected jejunum. Histological examination confirmed the presence of a jejunal ectopic pancreas. Adult intussusception caused by EP represents 5% of all cases of intussusception. As CT scan, especially when performed in emergency setting for small bowel obstruction diagnosis, can usually demonstrate nondiagnostic findings suggestive of intussusception of unknown origin, laparoscopic exploration could help surgeons in order to perform a resolute diagnosis and treat the pathology.

A long-term evaluation of the quality of life after laparoscopic Nissen-Rossetti anti-reflux surgery.

BACKGROUND: The quality of life (QoL) has been suggested to be the most relevant parameter to assess and monitor the long-term outcome in patients who underwent surgery for gastroesophageal reflux disease (GERD). PATIENTS AND METHODS: A retrospective evaluation was conducted on patients who underwent Laparoscopic Nissen-Rossetti Fundoplication for GERD between January 1998 and December 2010. To evaluate the long-term results a telephone interview was made using the VISICK score and the GERD-health-related QoL (HRQL) questionnaire at 1, 3, 5 years and at the end of the study. If the questionnaires resulted unsatisfactory, a complete diagnostic revaluation was performed. RESULTS: A total of 168 patients underwent laparoscopic surgery for GERD. When evaluated at the end of the study, the number of unsatisfied patients according to the VISICK score was significantly higher than the one obtained with the GERD-HRQL questionnaire. CONCLUSIONS: Many data suggest a possible recurrence of the symptoms after surgery in a long follow-up period. Our data seem to demonstrate a slight but significant trend in symptoms relapse after surgery. Considering the non-specific and specific nature of the two scores, VISICK and GERD HRQL, our result showed a significantly more relevant trend of symptoms relapse only for the non-specific ones. Such QoL scores seem to be important in selecting patients who need to be instrumentally examined. Consequently, our work proves that only a few patients out of the total number of followed up patients, are to be recalled to undergo instrumental examination.

Abdominal paragangliomas: a quantitative prognostic score as predictive factor of the feasibility of the laparoscopic approach.

The gold standard treatment for abdominal paraganglioma is the complete surgical excision. The surgical approach may be either open or laparoscopic. The aim of this study is to identify clinical-pathological predictive factors for the failure of the laparoscopic approach in the treatment of abdominal paragangliomas, with the aim of reducing the rate of conversion to the open technique. A retrospective review was conducted on the medical records of patients who underwent laparoscopic surgery for suspected abdominal paraganglioma. To validate parameters which usually act as predictive factors for the laparoscopic outcome in many other interventions, we retrospectively designed a quantitative prognostic score at the beginning of our experience with paragangliomas. The score was based on the clinical and pathological aspects of the disease, as the localization of the tumor in the abdominal cavity, its size, the proximity to major vessels, and the grade of vascularization. At the time of each patient's discharge, we retrospectively verified the score values. A group of 15 patients underwent laparoscopic surgery for abdominal paraganglioma. In two patients, laparoscopic procedures were converted to laparotomic approaches. Patients reporting a score of ≤3 were all successfully operated laparoscopically, while patients with a score between 5 and 6 were laparotomically converted. There are very few studies assessing the effectiveness of the laparoscopic technique in paragangliomas. The conversion rate of our procedures was still low compared to the mean rate reported in the major studies in the literature. Our scoring system, herewith presented, seeks to avoid time-consuming surgery, which may imply a high risk of intra-operative haemodynamic instability in such patients. The choice of the right approach would minimize blood loss and the consequent surgical stress, improving post-operation outcome.

Surgical outcome of pancreaticoduodenectomy: high volume center or multidisciplinary management?

BACKGROUND: More recently mortality and morbidity related to PD has dramatically dropped, due to the new mini-invasive technology as well as to a trend leading towards centralization. Our hospital can be considered a high-volume center for pancreatic surgery; nevertheless, each of its 5 surgical units taken alone has a low/medium-volume activity. The aim of this study was to evaluate the results of PD in a low-medium volume unit with multidisciplinary support in a major high-volume hospital. METHODS: A retrospective review was conducted: from January 2002 up to December 2013, 62 Whipple procedures were performed in our surgical unit. RESULTS: As to the operative outcome, the average number of days spent in ICU was of 4.28, the average days ventilated were 1.5 and the mean hospital stay was of 16 days. The in-hospital mortality was 3.2%, the late mortality was 1.6% and the perioperative morbidity was 27.4%. CONCLUSIONS: The effect of the surgeon volume on post-operative mortality is still controversial. As suggested by Gooiker, the centralization initiatives for pancreatic surgery should be based not only on volume quality criteria, but also on services and processes offered by a major hospital. The results of our study are similar to the ones of Italian and international studies performed in high-volume centers. According to our experience, we feel we can confirm that positive results in pancreatic surgery may be obtained also in low-medium volume units if there is a multidisciplinary support and services common to a major high volume hospital.

Laparoscopic total mesorectal excision for extraperitoneal rectal cancer: long-term results.

UNLABELLED: The long-term role of laparoscopy in the treatment of rectal cancer is still controversial. The aim of the present study was to evaluate the safety, the feasibility, the perioperative outcome, and the long-term results of laparoscopic total mesorectal excision (TME) for extraperitoneal rectal cancer considering a single center series. METHODS: Data about 186 unselected consecutive patients that underwent laparoscopic TME for middle and low rectal cancer between January 2001 and December 2011 were prospectively recorded and were included in the present study. RESULTS: Distribution of TNM stage was 5 % T1, 37 % T2, 52.5 % T3, and 6 % T4. Fifty-one percent of patients have lymph node metastases. The average duration of surgery was 234 min. Fourteen patients required conversion (7.5 %). A complete microscopic excision was achieved in 169 patients (91 %). The mean hospital stay was 9 days. The overall postoperative morbidity rate was 24 %. Surgical-related complications were reported in 19 %. Overall mortality was 0.5 %. Sex, tumor level, and the presence of a stoma were the only statistically significant independent risk factors for anastomotic leakage. Median follow-up was 71 months. The 5-year overall survival rate was 77 %, with 89 % for stage 1, 81 % for stage 2, 43 % for stage 3, and 10 % for stage 4. The 5-year disease-free survival rate was 66 %. The 10-year survival rate was 54 %. Nine patients (4.8 %) experienced a pelvic recurrence. Late metastases developed in 31 patients (17.2 %). CONCLUSIONS: The study confirms the oncological safety of laparoscopic TME in a long follow-up period.

Laparoscopic splenectomy 15 years after.

OBJECTIVE: The authors aim to analyze the impact of spleen size on the operative time, the splenic weight, the surgical technique, and the immediate clinical outcome in a series of 116 laparoscopic splenectomies (LS) performed in our department in the last 15 years. This study was also aimed to evaluate the efficacy of hand-assisted LS for splenomegaly. MATERIALS AND METHODS: From July 1995 to January 2010, 116 LS were performed. In all the procedures, the 3- or 4-trocar lateral approach was used. The mean indication for surgery was hematologic diseases. RESULTS: Of the 116 patients (69 females, mean age 41.7), the average weight of the spleens removed was about 450 g. The mean operative time was 100 minutes. Five patients underwent conversion. The mean duration of postoperative hospitalization was 4 days. No long-term complications were reported. Postoperative complications were reported in 3.5% of the cases. CONCLUSIONS: The laparoscopic approach is safe and effective, with a shorter hospital stay and improved morbidity and mortality. LS may be considered as an acceptable indication even in cases of massive splenomegaly, and hand-assisted LS could be considered as a viable alternative to open surgery in patients with massive spleens.

Cytoreduction and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal carcinomatosis from pseudomyxoma peritonei.

AIM: To investigate the most important aspects of hyperthermic intraperitoneal chemotherapy (HIPEC) that has been accepted as the standard treatment for pseudomyxoma peritonei (PMP), with special regard to morbidity, overall survival (OS) and disease free survival (DFS) over 10 years. METHODS: Fifty-three patients affected by PMP underwent cytoreduction (CCR) and HIPEC with a "semi-closed" abdomen technique in our institution. The peritonectomy procedure and completeness of CCR were classified according to Sugarbaker criteria. Preoperative evaluation always included thoracic and abdominal CT scan to stage peritoneal disease and exclude distant metastases. Fifty-one patients in our series were treated with a protocol based on administration of cisplatinum 100 mg/m(2) plus mitomycin C 16 mg/m(2), at a temperature of 41.5 degrees centigrade for 60 min. Anastomoses were always performed at the end of HIPEC. The mean duration of surgery was 12 h including HIPEC. Continuous monitoring of hepatic and renal functions and hydroelectrolytic balance was performed in the postoperative period. RESULTS: Twenty-four patients presented with postoperative complications: surgical morbidity was observed in 16 patients and 6 patients were re-operated. All complications were successfully treated and no postoperative deaths were observed. Risk factors for postoperative morbidity were considered to be gender, age, body surface, duration of surgery, Peritoneal Cancer Index (PCI) and tumor residual value (CC score). No statistically significant correlation was found during the multivariate analysis: only the CC score was statistically significant. The OS in our experience was 81.8%, with a DFS of 80% at 5 years and of 70% at 10 years. CONCLUSION: In our experience, even if HIPEC combined with cytoreductive surgery involves a high risk of morbidity, postoperative complications can be resolved favorably in most cases with correct patient selection and adequate postoperative care, thus minimizing mortality. The association of CCR and HIPEC can be considered as the standard treatment for PMP. The OS and DFS results confirm the validity of this combined approach for the treatment of this rare neoplasm. The impact of preoperative chemotherapy on OS, in our opinion, is due to a major aggressiveness of tumors in treated patients.

Video-assisted thoracoscopy in the early diagnosis and management of post-traumatic pneumothorax and hemothorax.

BACKGROUND: Blunt and penetrating chest traumas continue to be associated with a high mortality rate. The related morbidity rate is a also cause for concern because it may result in extended hospitalization and permanent disabilities. The aim of this study was to retrospectively review a series of consecutive patients treated for chest trauma between 1 January 2000 and 31 December 2005, focusing particularly on cases of pneumothorax and hemothorax. alone or in combination, and to critically assess the treatment protocol adopted. METHODS: Eighty-one patients with pneumothorax and/or hemothorax were subdivided into two groups. Group I (n = 46) comprised 36 patients with an Injury Severity Score (ISS) <9 and 10 patients with ISS from 9 to 15, all of whom were treated with chest tube alone. Group II (n = 35) included 34 patients with an ISS >9 who were treated with tube thoracostomy and VATS and 1 patient was treated by emergency thoracotomy. RESULTS: The time to complete recovery was virtually identical in both groups. CONCLUSIONS: In light of their own experience and of reports in the literature confirming both the diagnostic and therapeutic efficacies of VATS in chest trauma with pneumothorax and/or hemothorax, the authors propose a treatment protocol prescribing its use 48 h from the traumatic event in all cases of uncontrolled air and/or blood loss. This protocol yielded excellent results, including an uneventful postoperative course, rapid resolution of the signs and symptoms of the chest problem, and no disabling sequelae (empyema and fibrothorax), as well as a relatively shorter hospital stay and hence lower costs than with conservative treatment.
