Minimally invasive management of postoperative esophagojejunal anastomotic leak

Analysis of postoperative morbidity and mortality following surgery for gastric cancer. Surgeon volume as the most significant prognostic factor

Introduction

Surgical resection is the only potentially curative modality for gastric cancer and it is associated with substantial morbidity and mortality.

Aim

To determine risk factors for postoperative morbidity and mortality following major surgery for gastric cancer.

Material and methods

Between 1.08.2006 and 30.11.2014 in the Department of Oncological Surgery of Gdynia Oncology Centre 162 patients underwent gastric resection for adenocarcinoma. All procedures were performed by 13 surgeons. Five of them performed at least two gastrectomies per year (n = 106). The remaining 56 resections were done by eight surgeons with annual volume lower than two. Perioperative mortality was defined as every in-hospital death and death within 30 days after surgery. Causes of perioperative deaths were the matter of in-depth analysis.

Results

Overall morbidity was 23.5%, including 4.3% rate of proximal anastomosis leak. Mortality rate was 4.3%. Morbidity and mortality were not dependent on: age, gender, body mass index, tumour location, extent of surgery, splenectomy performance, or pTNM stage. The rates of morbidity (50% vs. 21.3%) and mortality (16.7% vs. 3.3%) were significantly higher in cases of tumour infiltration to adjacent organs (pT4b). Perioperative morbidity and mortality were 37.5% and 8.9% for surgeons performing less than two gastrectomies per year and 16% and 0.9% for surgeons performing more than two resections annually. The differences were statistically significant (p = 0.002, p = 0.003).

Conclusions

Annual surgeon case load and adjacent organ infiltration (pT4b) were significant risk factors for morbidity and mortality following major surgery for gastric cancer. The most common complications leading to perioperative death were cardiac failure and proximal anastomosis leak.

Results of Endoscopic and Surgical Fistula Treatment in Esophagointestinal Anastomosis After Gastrectomy

INTRODUCTION

Intestinal fistulas occur in 4% to 8% of cases of upper gastrointestinal tract surgery. Until now, this type of surgery has been the standard for treating fistulas in esophagointestinal anastomosis. The use of stents and hemoclips is still controversial, but an increasing number of publications have been presenting good results with this type of treatment.

OBJECTIVE

The objective of the study was to investigate the outcome of endoscopic and surgical treatment of fistulas in esophagointestinal anastomosis after gastrectomy.

MATERIALS AND METHODS

Fistulas in esophagointestinal anastomoses were observed in 23 patients (4.8%) over an 18-year period. The indications for endoscopic treatment were small (<50 mL/d) and large (>50 mL/d) fistulas in patients with no symptoms of peritonitis or abscess, who were treated with implantation of a covered stent.Surgical intervention was carried out for large fistulas that resulted in peritonitis and complicated gangrene of margins and/or abscesses.

RESULTS

Four subjects were treated endoscopically with hemoclips, resulting in 50% technical and clinical success. We implanted stents in 12 patients. Technical success was achieved in all patients; yet, permanent closure of the fistula was reported in 8 subjects (66%). Thirty-three percent of patients were operated upon for fistulas. We reported 4 deaths in this group.

CONCLUSIONS

The use of hemoclips in the treatment of small fistulas and of self-expandable covered stents in the treatment of medium and large fistulas is an effective method that shortens the hospitalization period and accelerates the introduction of oral nutrition while reducing the number of fatal complications.

Results of endoscopic and surgical fistula treatment in oesophagointestinal anastomosis after gastrectomy

Introduction

Intestinal fistulas occur in 4–8% of cases of upper gastrointestinal tract surgery. Until now, surgery has been the standard of treating fistulas in oesophagointestinal anastomosis. The use of stents and haemoclips still causes much controversy, but more and more publications present good results with this type of treatment.

Aim

To present results of endoscopic and surgical treatment of fistulas in oesophagointestinal anastomosis after gastrectomy.

Material and methods

A fistula in the oesophagointestinal anastomosis was observed in 23 (4.8%) patients within an 18-year period. The indications for endoscopic treatment were small fistulas (< 50 ml/day), and large (> 50 ml/day) fistulas in subjects with no symptoms of peritonitis or abscess were treated with implantation a of covered stent. Surgical treatment was performed with a large fistula leading to peritonitis and complicated gangrene of margins and/or the presence of abscess.

Results

Four subjects were treated endoscopically with the use of haemoclips, resulting in 50% technical and clinical success. We implanted stents in 12 patients. Technical success was achieved in all the patients, yet permanent closure of the fistula was reported for 8 (66%) subjects. The percentage of patients operated on for fistula was 33%. We recorded 4 deaths in this group.

Conclusions

The use of haemoclips in treatment of small fistulas, and self-expandable, covered stents in treatment of medium and large fistulas, is an effective method that shortens the hospitalisation period and accelerates introduction of oral nutrition while reducing the number of fatal complications.
