Small bowel obstruction: a prognostic score index for surgery - a review.

Bowel obstruction is an important cause of morbidity and mortality, accounting for nearly 30,000 deaths and more than $3 billion per year in direct medical costs. Small bowel obstruction (SBO) is caused mainly by postoperative adhesions. Adhesive small bowel obstruction (ASBO) is one of the leading causes of surgical emergencies and in particular of surgical emergencies that require an emergent operation. Hence, in this review article we attempted to narrate the role of the prognostic score index in the management of small bowel obstruction. Various prediction score index models developed by various authors were discussed in this review article, with the aim to delineate the role of the prognostic score index for making a decision about the surgery of patients suffering from SBO to prevent further complications like strangulation, malignancy etc. The use of prediction score index models was deliberated in this review article; widespread implementation in the treatment of patients with SBO has the potential to improve patient outcomes and reduce resource consumption.

Robotic esophagomyotomy for achalasia: technical note and review of the literature.

INTRODUCTION: The treatment of achalasia has undergone a continuous evolution with the advancement of technology. Since the beginning of the new millennium, the employment of robotics has led to technical facilitation with the execution of the myotomy and consequently to an improvement of the outcomes and a decrease in perioperative morbidity. EVIDENCE ACQUISITION: We provide a detailed description of the surgical procedure and the perioperative management together with a literature search of Electronic PubMed/Medline database and Cochrane Library. English written studies on robotic assisted myotomy (case reports, reviews, single arm and comparative studies) were included. Between 2001 and 2020, 10 case reports, 13 single arm studies, 10 comparative studies, 2 meta-analysis, 11 reviews and 2 technical notes on robotic assisted esophagomyotomy for achalasia were published. EVIDENCE SYNTHESIS: As reported by the studies available in the literature and evaluated in this manuscript, robotic assisted cardiomyotomy seems not only feasible but also a safer operation compared with traditional laparoscopic Heller myotomy, due to a significant lower incidence of intraoperative esophageal perforation. CONCLUSIONS: Also if large and randomized controlled studies are advocated, robotic assisted esophago-cardiomyotomy might be considered superior to laparoscopic Heller myotomy that, until now, is mostly considered the gold standard in the surgical treatment of achalasia.

Laparoscopic conversion of an omega in a Roux-en-y reconstruction after mini-invasive total gastrectomy for cancer: a technical report.

INTRODUCTION: Few cases of laparoscopic total gastrectomy have been published. Reconstruction of the digestive tract was generally accomplished with a Roux-en-y esophagojejunal mechanical anastomosis. Here we report the first 2 cases of laparoscopic conversion of an omega in a Roux-en-y reconstruction due to the occurrence of a severe alkaline esophagitis after mini-invasive total gastrectomy for cancer. MATERIALS AND METHODS: Two male patients presented in 2004. One year prior, at another facility, they had undergone laparoscopic total gastrectomy for cancer, with reconstruction of digestive tract by means of an esophagojejeunostomy with a jejunal loop and Braun's side-to-side enteroanastomosis. They complained of daily symptoms of nausea, regurgitation, heartburn, and early postprandial fullness with reduction of appetite and weight loss of almost 15 kg. Instrumental examination diagnosed alkaline esophagitis. Intervention was performed via laparoscopic approach and the digestive reconstruction was reconfigured in a Roux-en-y type with a proximal limb of almost 60 cm. RESULTS: Operative time was 135 to 180 minutes. No postoperative complications occurred. After 1-year follow-up, symptoms resolution and esophagitis healing have been observed in both patients. CONCLUSIONS: Laparoscopic gastrectomy is gaining wide acceptance. In our opinion, a standardization of the technique is necessary: we believe Roux-en-y should be considered the preferred reconstruction route ensuring the best protection of the esophagus from alkaline reflux.

A mesenteric window to approach a posterior side leak after laparoscopic assisted stapled strictureplasty for Crohn's disease.

Strictureplasty leak in patients with Crohn's disease increases considerably morbidity rate. Intra-operative evaluation of the integrity of suture line and proficient management of any leakage after strictureplasty is mandatory to prevent post-operative complications. When a leakage is detected at the posterior side, through intra-operative insufflation or methylene blue test, it may be difficult to repair as the suture line is completely covered up by mesentery. The AA. describe the creation of a mesenteric window to reinforce the posterior side of a side-to-side stapled strictureplasty performed by laparoscopic assisted procedure. As far as we know, this new technical strategy may allow avoiding resection of small bowel.

Gastroesophageal junction adenocarcinoma: what are the factors influencing long-term survival?

The incidence of gastroesophageal junction adenocarcinoma is increasing. About 30% of the tumors cannot be completely resected, and 40% of the patients relapse after complete resection. There is much controversy over the role of neoadjuvant therapy, the approach route, lymphadenectomy, and the extent of esophageal resection. The aim of our study was to report our experience in the treatment of gastroesophageal junction adenocarcinoma. From January 1987 until February 2005, 157 patients (125 men, 32 women), mean age 72.1 +/- 3.2 years, came for observation. One hundred sixteen patients underwent curative intervention. Mean operative time was 185 +/- 45 minutes. Mean postoperative hospital stay was 16.4 +/- 6.1 days. Postoperative complications were observed in 25 patients (21.6%); 6 patients (5.2%) died during the postoperative period. Overall survival was 36.2% and 27.6% at 3- and 5-year follow-up, respectively. Five-year survival rate was significantly lesser in R1/R2 versus R0 resections (0% versus 33.7%), N+ versus N- patients (11.3% versus 53.3%), and worsened with progression of pT histological staging (T1, 100%; T2, 24.1%; T3, 15.1%; T4, 0%). Determining prognostic factors are the radicality of resection, lymph nodal invasion, and histological staging.

The role of scintigraphic defecography in the assessment of bowel function after restorative proctocolectomy for ulcerative colitis.

BACKGROUND: The aim of the study was to evaluate the efficiency of defecation in patients with ileal pouch for ulcerative colitis by using the mean of scintigraphic defecography. METHODS: Sixteen patients were classified into two groups according to the presence of good (group A) or poor (group B) pouch function. Emptying efficiency was calculated by scintigraphic defecography and measured as percentage of evacuation. This involves the use of up to 200 ml of an artificial stool made up of methyl cellulose paste labeled with 180 MBq of technetium-99 m (Tc-99 m) methylene diphosphonate. Potential causes of increased frequency in the absence of additional associated symptoms of dysfunction were excluded in all patients. Maximum tolerated volume (MTV) and balloon expulsion tests were also performed on all patients. RESULTS: No patient in both groups showed evidence of organic pouch dysfunction. Percentage of emptying was higher in patients of group A (n=6) than in group B (n=10) (81+/-9 vs 71+/-9%, respectively, P<0.05; correlation, -0.51, P<0.04). Mean MTV was similar in the two groups (group A: 361+/-118 ml and group B: 338+/-77 ml, P=0.7). Results of the balloon expulsion test were normal in all patients except for one individual in group B. CONCLUSION: In patients with ileal pouch for ulcerative colitis, increased frequency of defecation without any evidence of pouch dysfunction may be correlated with an alteration of emptying efficiency. Scintigraphic defecography is appropriate to use for investigation of this condition with no disadvantages for the patients.
