Challenges in abdominal re-exploration for war casualties following on-site abdominal trauma surgery and subsequent delayed arrival to definitive medical care abroad - an unusual scenario

Background

During the Syrian civil war, patients were initially treated on-site in Syria and later transferred to medical centers in Israel. Relevant details concerning the exact nature of injury and medical/surgical care received in Syria were unavailable to clinicians in Israel. Many of these patients required abdominal re-exploration for obvious or suspected problems related to their injury. Our aim is to present our approach to abdominal trauma patients who survived initial on-site surgery and needed subsequent abdominal re-exploration abroad, in our medical center.

Methods

Clinical data from all medical records were retrospectively analyzed. Each patient underwent total body computerized tomography on arrival, revealing diverse multi-organ trauma. We divided the patient population who had abdominal trauma into 4 sub-groups according to the location in which abdominal surgical intervention was performed (abdominal surgery performed only in Syria, surgery in Syria and subsequent re-laparotomy in Israel, abdominal surgery only in Israel, and management of patients without abdominal surgical intervention). We focused on missed injuries and post-operative complications in the re-laparotomy sub-group.

Results

By July 2018, 1331 trauma patients had been admitted to our hospital, of whom 236 had suffered abdominal trauma. Life-saving abdominal intervention was performed in 138 patients in Syria before arrival to our medical center.

A total of 79 patients underwent abdominal surgery in Israel, of whom 46 (33%) required re-laparotomy. The absence of any communication between the surgical teams across the border markedly affected our medical approach. Indications for re-exploration included severe peritoneal inflammation, neglected or overlooked abdominal foreign bodies, hemodynamic instability and intestinal fistula. Mortality occurred in 37/236 patients, with severe abdominal trauma as the main cause of fatality in 10 of them (4.2%), usually following urgent re-laparotomy.

Conclusions

Lack of information about the circumstances of injury in an environment of catastrophe in Syria at the time and the absence of professional communication between the surgical teams across the border markedly dictated our medical approach. Our concerns were that some patients looked deceptively stable while others had potentially hidden injuries. We had no information on who had had definitive versus damage control surgery in Syria. The fact that re-operation was not performed by the same team responsible for initial abdominal intervention also posed major diagnostic challenges and warranted increased clinical suspicion and a change in our standard medical approach.

Indications and Outcome of Patients who had Re-Laparotomy: Two Years' Experience from a Teaching Hospital in a Developing Nation

Background

Complications from abdominal surgery may necessitate a second or more surgeries, re-laparotomy. It is associated with significant morbidity and mortality. Data on relaparotomy from the developing nations is limited. This study aims to assess the indications and outcome of patients who had relaparotomy.

Methods

A retrospective review of medical records of all patients who underwent Re-laparotomy at St. Paul's Hospital Millennium Medical College from January 2016 to December 2017 was done.

Result

Of 2146 laparotomies, 6.9% (149) needed re-laparotomy and 129 patients were analyzed. Most (123,95.3%) had on-demand re-laparotomy. Patients operated on emergency made 70.5% (91) of the cases making the ratio of emergency to elective surgery 2.4:1. The three most common surgeries that needed re-laparotomy were, Perforated appendicitis (35,27.1%), bowel obstructions (28,21.7%) , and trauma (20,13.4%). The most common indications for relaparotomy were intra-abdominal abscess (57,44.23%), wound dehiscence (17,13.2%) and anastomotic leak (15 ,11.6%). Surgical site infection (128,100%) and malnutrition (58,45%) were the leading complications. The overall mortality rate was 12.8 % (19). There was no statically significant difference in mortality rate between on-demand and planned re-laparotomy (P=0.388), urgency of the primary surgery (P=0.891) and the number of relaparotomy (p=0.629). Re-laparotomy for anastomotic leak (p=0.001) and patients above fifty years of age (P=0.015) had significant associations with mortality.

Conclusion

Intra-abdominal abscess collection, wound dehiscence and anastomotic leak were the most common indications of re-laparotomies. Age above fifty years and anastomotic leaks were significantly associated with mortality.

Outcomes of early relaparotomy in pediatric patients at Tikur Anbessa teaching hospital, Addis Ababa, Ethiopia: a five-year retrospective review

BACKGROUND

Early relaparotomy is defined as relaparotomy within the first 30 days following surgery. The aim of this study is to explore the indications, outcomes and factors associated with relaparotomy in our pediatric population.

METHODS

We performed a retrospective study of pediatric surgical patients (< 13 yrs.) who underwent relaparotomy at Tikur Anbessa Teaching Hospital between September 1, 2011 and August 31, 2016. All children who had relaparotomy within the first 30 days of the initial surgery were included. We collected patient data including demographics, operative indication, and postoperative outcomes. Data analysis was performed using SPSS Version 23. Chi-square and Fisher's exact tests were used to report outcomes stratified by patient characteristics. Multivariable logistic regression was used to identify patient variables associated with relaparotomy and other outcomes.

RESULTS

In our patient population, relaparotomy rate was 17.2%. Patient age ranged from 2 days to 12 years with mean age of 37.5 months. Male to female ratio was 1.2:1. Thirty-one (58.5%) relaparotomies were performed between the 5th and 8th postoperative days. The two most common indications for relaparotomy were postoperative intra-abdominal collection and anastomotic leak, accounting for 18 (34.0%) and 17 (32.1%) respectively. Mortality rate following relaparotomy was 26.4%. The most common cause of mortality was sepsis with multi-system organ failure (90.6%). Neonatal age was found to be the independent risk factors for death following relaparotomy, (AOR = 27.59, 95% CI [2.0-379.9]).

CONCLUSION

Prevalence of relaparotomy in pediatric patients is high (17.2%) in our patient population. Neonatal age was associated with increased mortality following relaparotomy.

Diagnosis and Treatment of Abdominal Arterial Bleeding After Radical Gastrectomy: a Retrospective Analysis of 1875 Consecutive Resections for Gastric Cancer

BACKGROUND

Massive abdominal arterial bleeding is an uncommon yet life-threatening complication of radical gastrectomy. The exact incidence and standardized management of this lethal morbidity are not known.

METHODS

Between January 2003 and December 2013, data from 1875 patients undergoing radical gastrectomy with D2 or D2 plus lymphadenectomy were recorded in a prospectively designed database from a single institute. The clinical data and management of both early (within 24 h) and late (beyond 24 h) postoperative abdominal arterial hemorrhages were explored. For late bleeding patients, transcatheter arterial embolization (TAE) and re-laparotomy were compared to determine the better initial treatment option.

RESULTS

The overall prevalence of postoperative abdominal arterial bleeding was 1.92 % (n = 36), and related mortality was 33.3 % (n = 12). Early and late postoperative bleedings were found in 6 and 30 patients, respectively. The onset of massive arterial bleeding occurred on average postoperative day 19. The common hepatic artery and its branches were the most common bleeding source (13/36; 36.1 %). All the early bleeding patients were treated with immediate re-laparotomy. For late bleeding, patients from the TAE group had a significantly lower mortality rate than that of the patients from the surgery group (7.69 vs. 56.25 %, respectively, P = 0.008) as well as a shorter procedure time for bleeding control (2.3 ± 1.1 vs. 4.8 ± 1.7 h, respectively, P < 0.001). Four rescue reoperations were performed for TAE failures; the salvage rate was 50 % (2/4). Ten patients developed massive re-bleeding after initial successful hemostasis by either TAE (5/13) or open surgery (5/16). Three out of the 10 re-bleeding patients died of disseminated intravascular coagulation (DIC), while the other 7 recovered eventually by repeated TAE and/or surgery.

CONCLUSION

Abdominal arterial bleeding following radical gastrectomy tends to occur during the later phase after surgery, with further complications such as abdominal infection and fistula(s). For late bleeding, TAE can be considered as the first-line treatment when possible.

Planned re-laparotomy and the need for optimization of physiology and immunology

Planned re-laparotomy or damage control laparotomy (DCL), first described by Dr. Harlan Stone in 1983, has become a widely utilized technique in a broad range of patients and operative situations. Studies have validated the use of DCL by demonstrating decreased mortality and morbidity in trauma, general surgery and abdominal vascular catastrophes. Indications for planned re-laparotomy include severe physiologic derangements, coagulopathy, concern for bowel ischemia, and abdominal compartment syndrome. The immunology of DCL patients is not well described in humans, but promising animal studies suggest a benefit from the open abdomen (OA) and several human trials on this subject are currently underway. Optimal critical care of patients with OA's, including sedation, paralysis, nutrition, antimicrobial and fluid management strategies have been associated with improved closure rates and recovery.
