Laparoscopy is an available alternative to open surgery in the treatment of perforated peptic ulcers: a retrospective multicenter study.

BACKGROUND: Perforated peptic ulcers (PPU) remain one of the most frequent causes of death. Their incidence are largely unchanged accounting for 2-4% of peptic ulcers and remain the second most frequent abdominal cause of perforation and of indication for gastric emergency surgery. The minimally invasive approach has been proposed to treat PPU however some concerns on the offered advantages remain. METHODS: Data on 184 consecutive patients undergoing surgery for PPU were collected. Likewise, perioperative data including shock at admission and interval between admission and surgery to evaluate the Boey's score. It was recorded the laparoscopic or open treatments, the type of surgical procedure, the length of the operation, the intensive care needed, and the length of hospital stay. Post-operative morbidity and mortality relation with patient's age, surgical technique and Boey's score were evaluated. RESULTS: The relationship between laparoscopic or open treatment and the Boey's score was statistically significant (p = 0.000) being the open technique used for the low-mid group in 41.1% and high score group in 100% and laparoscopy in 58.6% and 0%, respectively. Postoperative complications occurred in 9.7% of patients which were related to the patients' Boey's score, 4.7% in the low-mid score group and 21.4% in the high risk score group (p = 0.000). In contrast morbidity was not related to the chosen technique being 12.8% in open technique and 5.3% in laparoscopic one (p = 0.092, p > 0.05). 30-day post-operative mortality was 3.8% and occurred in the 0.8% of low-mid Boey's score group and in the 10.7% of the high Boey's score group (p = 0.001). In respect to the surgical technique it occurred in 6.4% of open procedures and in any case in the Lap one (p = 0.043). Finally, there was a statistically significant difference in morbidity and mortality between patients < 70 and > 70 years old (p = 0.000; p = 0.002). CONCLUSIONS: Laparoscopy tends to be an alternative method to open surgery in the treatment of perforated peptic ulcer. Morbidity and mortality were essentially related to Boey's score. In our series laparoscopy was not used in high risk Boey's score patients and it will be interesting to evaluate its usefulness in high risk patients in large randomized controlled trials.

The abdominal wall hernia in cirrhotic patients: a historical challenge.

Background: The incidence rate of abdominal wall hernia is 20-40% in cirrhotic patients. A surgical approach was originally performed only if complication signs and symptoms occurred. Several recent studies have demonstrated the usefulness of elective surgery. During recent decades, the indications for surgical timing have changed. Methods: Cirrhotic patients with abdominal hernia who underwent surgical operation for abdominal wall hernia repair at the Policlinico "Paolo Giaccone" at Palermo University Hospital between January 2010 and September 2016 were identified in a prospective database, and the data collected were retrospectively reviewed; patients' medical and surgical records were collected from charts and surgical and intensive care unit (ICU) registries. Postoperative morbidity was determined through the Clavien-Dindo classification. Cirrhosis severity was estimated by the Child-Pugh-Turcotte (CPT) score and MELD (model of end-stage liver disease) score. Postoperative mortality was considered up to 30 days after surgery. A follow-up period of at least 1 year was used to evaluate hernia recurrence. Results: The univariate and multivariate analyses demonstrated the unique independent risk factors for the development of postsurgical morbidity (emergency surgery (OR 6.42; p 0.023), CPT class C (OR 3.72; p 0.041), American Society of Anesthesiologists (ASA) score ≥ 3 (OR 4.72; p 0.012) and MELD ≥ 20 (OR 5.64; p 0.009)) and postsurgical mortality (emergency surgery (OR 10.32; p 0.021), CPT class C (OR 5.52; p 0.014), ASA score ≥ 3 (OR 8.65; p 0.018), MELD ≥ 20 (OR 2.15; p 0.02)). Conclusions: Concerning abdominal wall hernia repair in cirrhotic patients, the worst outcome is associated with emergency surgery and with uncontrolled disease. The correct timing of the surgical operation is elective surgery after ascites drainage and albumin/electrolyte serum level and coagulation alteration correction.

Vacuum-Assisted Wound Closure with Mesh-Mediated Fascial Traction Achieves Better Outcomes than Vacuum-Assisted Wound Closure Alone: A Comparative Study.

BACKGROUND: Open abdomen (OA) permits the application of damage control surgery principles when abdominal trauma, sepsis, severe acute peritonitis and abdominal compartmental syndrome (ACS) occur. METHODS: Non-traumatic patients treated with OA between January 2010 and December 2015 were identified in a prospective database, and the data collected were retrospectively reviewed. Patients' records were collected from charts and the surgical and intensive care unit (ICU) registries. The Acosta "modified" technique was used to achieve fascial closure in vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) patients. Sex, age, simplified acute physiology score II (SAPS II), abdominal compartmental syndrome (ACS), cardiovascular disease (CVD) and surgical technique performed were evaluated in a multivariate analysis for mortality and fascial closure prediction. RESULTS: Ninety-six patients with a median age of 69 (40-78) years were included in the study. Sixty-nine patients (72%) underwent VAWCM. Forty-one patients (68%) achieved primary fascia closure: two patients (5%) were treated with VAWC (37 median days) versus 39 patients (95%) who were treated with VAWCM (10 median days) (p = 0.0003). Forty-eight patients underwent OA treatment due to ACS, and 24 patients (50%) survived compared to 36 patients (75%) from the "other reasons" group (p = 0.01). The ACS group required longer mechanical ventilator support (p = 0.006), length of stay in hospital (p = 0.005) and in ICU (p = 0.04) and had higher SAPS II scores (p = 0.0002). CONCLUSIONS: The survival rate was 62%. ACS (p = 0.01), SAPS II (p = 0.004), sex (p = 0.01), pre-existing CVD (p = 0.0007) and surgical technique (VAWC vs VAWCM) (p = 0.0009) were determined to be predictors of mortality. Primary fascial closure was obtained in 68% of cases. VAWCM was found to grant higher survival and primary fascial closure rate.

Usefulness of ileostomy defunctioning stoma after anterior resection of rectum on prevention of anastomotic leakage A retrospective analysis.

PURPOSES: Anastomotic leakage is one of the major complications occurring after anterior resection of rectum. A defunctioning stoma is usually created routinely or on surgeons' discretion. The aim of this study was to investigate the usefulness of temporary ileostomy to prevent anastomotic leakage comparing the postoperative course of patients with and without defunctioning loop ileostomy. METHODS: Patients that underwent anterior resection of rectum were recruited. 140 patients were enrolled and divided in two groups: patients without and with defunctioning loop ileostomy. Patients' characteristics and other useful data were recorded. A comparison between the two groups was made. The minimum follow-up was 11 months. RESULTS AND CONCLUSIONS: 18.6% of patients had a symptomatic anastomotic leakage. We observed more anastomotic leakages after medium-low resections of rectum with anastomosis than after resections with high anastomosis (15.7% vs 2.9%; p=0.03). There were no significant differences in overall and related mortality between patients without/with ileostomy. The presence of ileostomy was not protective towards anastomotic leakage either in the medium-low resections or in the high ones but it was towards its consequences such as clinical features. Nevertheless we found a statistically significative difference between recurrence rate of leakage in patients with and without ileostomy (p-Value=0.009).

Three-port colectomy: reduced port laparoscopy for general surgeons. A single center experience.

AIM: To evaluate three-port colectomy as an alternative reduced-port laparoscopy technique in colonic surgery. MATERIAL OF STUDY: Retrospective study carried out through the analysis of 32 consecutive patients that underwent alternatively to a three ports left colectomy or a conventional laparoscopic colectomy for colonic diseases in order to evaluate the benefits of the reduced-port technique. A multivariate analysis among duration of surgery, hospital stay and conversion rate was performed using the OLS regression and the binary logistic regression. RESULTS: We found a reduced operative time in the three-port colectomy in comparison to the four-port technique (p=0.07). The hospital stay was not found related to the number of port. Conversion rate was higher in the three-port colectomy group and in patients admitted in emergency (p=0.009). DISCUSSION: We did not found difference between three-port and traditional lap in relation to hospital stay. The reduced port technique allows to reduce operative times even adds more conversions. CONCLUSIONS: Three-port colectomy seems an affordable reduced port laparoscopy technique. General surgeons can use it without the need of specific tools minimizing the port-related complications. KEY WORDS: Colon Colectomy, Laparoscopy, Three ports.

A primary subcutaneous hydatid cyst in the thigh A case report.

AIM: Hydatid disease is a parasitic disease considered endemic in many parts of the world such as South America, Middle East, Africa, Australia and the Mediterranean regions. Liver and lung hydatid disease accounts for 90% of all echinococcal cysts. Primary hydatid disease of subcutaneous sites is rare and the subcutaneous localization of a solitary hydatid cyst accounts for 1.6%. Not enough data exist for this localization, and only many heterogeneous data are described in order to define this rare condition. MATERIAL OF STUDY: We present the case of a 68-year-old-woman affected by a mass in upper-medial side of her right thigh with a 12-year-growing history. Anamnestic data were accurately collected. Many different radiological and specific serum tests were performed in order to define the diagnosis. Surgical approach was decided in order to excide the mass, and a 6-months follow-up was performed. CONCLUSIONS: Hydatid disease is common in endemic area but uncommon localizations, as in subcutaneous tissues, are a rare condition. Scientific Community lacks of complete and homogeneous data about the approach to this manifestation of the disease. Would be useful a complete review of the literature in order to plan guide-lines for the treatment of uncommon localization. KEY WORDS: Echinococcosis, Hydatid cyst, Subcutaneous localization.

Solitary metastasis from melanoma causing bowel perforation.

INTRODUCTION: Skin melanoma can metastasize to any organ or tissue. The median survival in patient with intestinal metastases is inferior to 7 months compared to other sites metastasis. A wide intestinal resection including the resection of the mesentery with lymph nodes remains the main treatment due to the low morbidity and mortality rate it is also associated with. CASE REPORT: We took under analysis a recent case of acute abdomen for small bowel perforation from intestinal metastases in a patient with metastatic melanoma who was under treatment with Pemrolizumab. A bowel resection was performed and no other lesions were found in the abdominal examination. However, the chemotherapy was stopped due to the advanced age of the patient, presence of brain metastases that worsening his performance status and the bowel involvement. DISCUSSION: Preoperative diagnoses of metastatic or small intestine melanoma tend to often be difficult to perform. Before considering a possible elective surgery, in case of non-urgent symptoms, it is important to value first intestinal or extraintestinal spread. The previous report of bowel perforation from melanoma metastases showed an intraoperative finding of multiple widespread brown lesions. There are not reports about the possible involvement of Pembrolizumab in bowel perforation, which leads to the conclusion that it was probably the ingrown of the metastasis to cause it. CONCLUSION: The treatment of metastatic melanoma includes chemotherapy, immunotherapy and target-therapy. It will be useful to do a multicenter study on the survival after complete resection to better define the surgical indication for the treatment of the metastatic disease. KEY WORDS: Intestinal perforation, Melanoma, Metastasis.

Colonic stenting in acutely obstructed left-sided colon cancer Clinical evaluation and cost analysis.

AIM: This retrospective study aims to evaluate clinical and cost effectiveness of colonic stenting as a bridge to surgery and as a palliative treatment in acutely obstructed left-sided colon cancer. MATERIAL AND METHODS: Onehundred fortyfour patients were collected between 2006 and 2012, with acute left-sided malignant colonic obstruction with no evidence of peritonitis: 96 patients underwent surgical treatment, 48 underwent decompressive stenting. For the stenting we used self-expandable metallic stent in nitinol. RESULTS: Patients who had successful colonic stenting were 40, 8 underwent elective surgery within 10 days, 32 decompression stenting had only palliative intent. in 8/48 patients subjected to stenting decompression there was a technical failure (16%) and underwent emergency surgery. 40 patients had follow-up. at the time of observation 36 patients had a functioning stent, within 10 days 8 underwent elective definitive colonic resection with primary anastomosis trought videolaparoscopic thecnical, 4 (10%) had major complications and underwent emergency surgery. no patient of 40 in the stenting group required defunctioning stomas compared to 38 of 96 in emergency surgery group. we also compared the cost of decompressive stenting and emergency surgery treatment in acutely obstructed left-sided colon cancer referring to average cost of drg (1 and 2 code t-student test). the comparison of the average costs between decompressive stenting and emergency surgery was performed in the group of patients underwent palliative treatment separately from ones underwent radical treatment. CONCLUSION: Colonic stenting followed by elective surgery may be safer and cost-effective, comparing to emergency surgery for left-sided malignant colonic obstruction.
