Bacteriological concentration of peritoneal drainage fluid could make an early diagnosis of anastomotic leakage following rectal resection

To investigate that the bacteriological concentration and pH value in peritoneal drainage fluid might serve as indicators of early diagnosis of anastomotic leakage following rectal resection. We prospectively analyzed consecutive patients who were treated for rectal diseases with anastomosis at the department of general surgery, the affiliated hospital of Nanjing University Medical School between August 2018 and December 2020. The bacteriological concentration and the pH value in peritoneal drainage fluid were tested on the first, fourth, seventh days postoperatively. A total of 300 consecutive patients underwent rectal resection were tested. 21 patients present with AL and the overall AL rate was 7%. The bacteriological concentration in peritoneal drainage fluid of AL group was significantly higher than that in non-AL group. The AUC value was 0.98 (95% confidence intervals 0.969–1.000) according to the ROC curve. The best cut-off value was 1143/uL. The sensitivity and specificity were 100% and 93.19% respectively. There was no difference of pH value between the AL and non-AL groups. According the results of present study, a high bacteriological concentration in peritoneal drainage fluid is a good marker for predicting and diagnosing AL following rectal resection. However, owing to the limitation of the sample, there was no validation attempt in the study. A large sample study is needed to validate the conclusion.

Prophylactic Intra-Peritoneal Drainage After Pancreatic Resection: An Updated Meta-Analysis

IntroductionProphylactic intra-peritoneal drainage has been considered to be an effective measure to reduce postoperative complications after pancreatectomy. However, routinely placed drainage during abdominal surgery may be unnecessary or even harmful to some patients, due to the possibility of increasing complications. And there is still controversy about the prophylactic intra-peritoneal drainage after pancreatectomy. This meta-analysis aimed to analyze the incidence of complications after either pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) in the drain group and no-drain group.MethodsData were retrieved from four electronic databases PubMed, EMBASE, the Cochrane Library and Web of Science up to December 2020, including the outcomes of individual treatment after PD and DP, mortality, morbidity, clinically relevant postoperative pancreatic fistula (CR-POPF), bile leak, wound infection, postoperative hemorrhage, delayed gastric emptying (DGE), intra-abdominal abscess, reoperation, intervened radiology (IR), and readmission. Cochrane Collaboration Handbook and the criteria of the Newcastle-Ottawa scale were used to assess the quality of studies included.ResultsWe included 15 studies after strict screening. 13 studies with 16,648 patients were analyzed to assess the effect of drain placement on patients with different surgery procedures, and 4 studies with 6,990 patients were analyzed to assess the effect of drain placement on patients with different fistula risk. For patients undergoing PD, the drain group had lower mortality but higher rate of CR-POPF than the no-drain group. For patients undergoing DP, the drain group had higher rates of CR-POPF, wound infection and readmission. There were no significant differences in bile leak, hemorrhage, DGE, intra-abdominal abscess, and IR in either overall or each subgroup. For Low-risk subgroup, the rates of hemorrhage, DGE and morbidity were higher after drainage. For High-risk subgroup, the rate of hemorrhage was higher while the rates of reoperation and morbidity were lower in the drain group.ConclusionsIntraperitoneal drainage may benefit some patients undergoing PD, especially those with high pancreatic fistula risk. For DP, current evidences suggest that routine drainage might not benefit patients, but no clear conclusions can be drawn because of the study limitations.

Outcome of primary peritoneal drainage in perforated necrotizing enterocolitis: an experience with 96 infants

Background: Necrotizing enterocolitis is a life-threatening inflammation of neonatal intestine of multifactorial etiology. In early stages, medical management is considered; while as a transmural disease with pneumatosis or perforation needs surgical attention. Primary peritoneal drainage has evolved as an alternative to classic exploratory laparotomy especially in sick preterm and very low birth weight infants.Methods: In our study, we tried to employ primary peritoneal drainage as an initial intervention in all surgical necrotizing enterocolitis patients and analyzed the results and final outcome in terms of total days in neonatal intensive care unit, total parenteral nutrition days, days to start oral feeds, need for laparotomy, mortality and other complications.Results: Around one-third patients were either very low or extremely low birth weight and 80% patients were preterm. Primary peritoneal drainage was successful without need for laparotomy in around 65% of patients. In the rest 34 patients, 24 were subjected to rescue laparotomy, while 10 could not be stabilized for major surgery. Overall mortality was 29.16%.Conclusions: Early bedside primary peritoneal drainage can be employed in all cases of NEC with perforation with rescue laparotomy to be determined by subsequent monitoring. This strategy seems to be safe and cost-effective in a resource challenged set up and lifesaving in sick and extremely low birth weight infants.

Endoscopic vacuum assisted closure of gastrocutaneous fistula after sleeve gastrectomy combined with fibrin sealant

Treatment of gastrointestinal fistulas after staple line leaks is difficult and non-invasive procedures such as endoclips, stents or endoscopic vacuum assisted closure (E-VAC) are sometimes not adequate. Fibrin sealants (FS) may promote healing, although today are used mainly to prevent anastomosis dehiscence within digestive tract. The authors present a 37-year-old female patient who developed a chronic gastrocutaneous fistula after sleeve gastrectomy for severe obesity treated successfully with a combination of E-VAC and a fibrin sealant. Long term peritoneal drainage, total parenteral nutrition, and antibiotic therapy for the next six weeks failed to close the leakage. Ultimately the fistula was closed after 6 changes of E-VAC and final implementation of a fibrin sealant. The duration of treatment was 81 days, including 34 days of E-VAC treatment and FS application. Complete closure of the fistula was visualized on gastroscopy six weeks after the treatment.

Bacteriological Concentration of Peritoneal Drainage Fluid Could Make an Early Diagnosis of Anastomotic Leakage Following Rectal Resection

Purpose: To investigate that the bacteriological concentration and pH value in peritoneal drainage fluid might serve as indicators of early diagnosis of anastomotic leakage following rectal resection.Methods: We prospectively analyzed consecutive patients who were treated for rectal diseases with anastomotic stoma at the department of general surgery, the affiliated hospital of Nanjing University Medical School between August 2018 and December 2020. The bacteriological concentration and the pH levels in peritoneal drainage fluid were tested on the first, fourth, seventh days postoperatively.Results: A total of 300 consecutive patients underwent rectal resection were tested. 21 patients present with AL and the overall AL rate was 7%. The bacteriological concentration in peritoneal drainage fluid of AL group was significantly higher than that in non-AL group. The AUC value was 0.98 according to the ROC curve. The best cut-off value was 1143/uL and the sensitivity and specificity were 100% and 93.19% respectively. There was no difference of pH value between the AL and non-AL groups. Conclusion: According the results of present study, a high bacteriological concentration in peritoneal drainage fluid is a good marker for predicting and diagnosing AL following rectal resection. The best cut-off value is1143/uL and the sensitivity and specificity are 100% and 93.19% respectively.

Minimally invasive management of traumatic biliary fistula in the setting of gastric bypass

The current management of persistent biliary fistula includes biliary stenting and peritoneal drainage. Endoscopic retrograde cholangiopancreatography (ERCP) is preferred over percutaneous techniques and surgery. However, in patients with modified gastric anatomy, ERCP may not be feasible without added morbidity. We describe a 37-year-old woman with traumatic biliary fistula, large volume choleperitonitis and abdominal compartment syndrome following a motor vehicle collision who was treated with laparoscopic drainage, lavage and biliary drain placement via percutaneous transhepatic cholangiography.

Laparoscopic Management of Primary Omental Torsion

Primary omental torsion is an unusual condition, known for its rarity and for the particularity of being intraoperatively diagnosed, in nearly all cases. At the clinical evaluation, this pathology commonly mimics other etiologies of acute abdomen. Hemoperitoneum and necrosis of the omentum are rarely associated with the omental torsion, but when the association is found, then it means that the vascular injuries are irreversible and the required surgical procedure may be far more complex than simple devolvulus. In search of the treatment of choice, laparoscopy proved its effectiveness as a diagnostic and therapeutic tool, while the open surgery approach can be described in many cases as being too invasive. A 37-year-old female patient presented with the generic symptoms of acute appendicitis. Surgical treatment was initiated. During laparoscopy, the abdomen was attentively explored, highlighting the presence of a twisted omentum with hemoperitoneum and necrosis. Omental excision and peritoneal drainage were performed. The evolution was favorable. Another check-up was done at 6 months postoperatively, displaying no signs or symptoms of relapse.
