[Management of surgical abdominal emergencies in Kara teaching hospital (Togo): 10-year retrospective study of 594 cases]

PURPOSE

The aim of this study was to describe the epidemiologic, diagnostic, and therapeutic aspects of surgical abdominal emergencies in a teaching hospital in a developing country (Togo).

MATERIAL AND METHOD

This retrospective study included the medical files of all patients managed for surgical abdominal emergencies from March 1, 2002, to March 1, 2012.

RESULTS

The study included 594 patients, with a mean age of 30.3 years (range: 1 month to 80 years) and a 2.1 male:female sex ratio. The emergencies were acute generalized peritonitis (54.5%), intestinal obstruction (26.6%), acute appendicitis (14.5%), and abdominal trauma (4.4%). Plain abdominal radiographs were taken for 414 patients with acute generalized peritonitis (324 cases) and intestinal obstructions without a strangulated hernia (90 cases). Nine patients had abdominal ultrasounds for abdominal trauma (5 cases) and appendicular abscess (4 cases). No abdominal CT scan was performed. All patients underwent surgery, 316 (53.2%) by physician assistants and 278 (46.8%) by surgeons. Resuscitation and anesthesia were performed by nurse-anesthetists. The postoperative course was complicated in 182 cases (30.7%). These complications included parietal suppurations (18.2%), eviscerations (5.1%), ileal fistulas (4.4%), and postoperative peritonitis (3%). The death rate was 11.4%.

CONCLUSION

Surgical abdominal emergencies at the Kara teaching hospital were both common and serious. Their particularly high morbidity and mortality might be reduced through the adoption of reasonably practicable measures: paramedical personnel training, public awareness, establishment of management protocols, and improvement of technical equipment (laboratory).

A pre-operative nomogram for decision making in oncological surgical emergencies

BACKGROUND

The purpose of the study was to propose a clinical decision-making tool for predicting mortality in patients undergoing emergency abdominal surgery with a palliative intent in the oncology setting.

METHODS

Identification of all emergency surgical procedures performed in a Department of Oncologic Surgery in a Comprehensive Cancer Center between January 2008 and January 2013. Multivariate logistic and Cox regression models were used to identify factors predicitve of mortality at 3 months and survival probabilities. Models were internally validated using bootstrapping and calibration.

RESULTS

The mortality rates were 30% at 1 month, 46.7% at 3 months and 83.3% at the end of the study. One model based on the albumin level and the P-POSSUM score (AUC: 0.725) adequately predicted mortality at 3 months. A survival nomogram predicted mortality with a concordance index (CI) of 0.718, using the following factors: WHO performance status (P = 0.02), albumin level (P < 0.01) and P-POSSUM score (P < 0.01). The origin or the extent of the carcinoma did not own sufficient pronostic impact to be selected in this model.

CONCLUSIONS

Pre-operative mortality risk scores can be developed in a palliative context. Physicians counselling and surgical decision making should be based on the use of these tools.

The laparoscopic approach in abdominal emergencies: a single-center 10-year experience

INTRODUCTION

Laparoscopy has rapidly emerged as the preferred surgical approach to a number of different diseases because it allows for a correct diagnosis and proper treatment. In abdominal emergencies, both components of treatment--exploration and surgery--can be accomplished via laparoscopy. The aim of the present work is to illustrate retrospectively the results of a case-control experience with laparoscopic versus open surgery for abdominal emergencies performed at our institution.

METHODS

From January 1992 to January 2002, 935 patients (mean age, 42.3+/-17.2 years) underwent emergent or urgent surgery, or both. Of these, 602 (64.3%) were operated on laparoscopically (small bowel obstruction, 28; gastroduodenal ulcer disease, 25; biliary disease, 165; pelvic disease, 370 cases; colonic perforations, 14) based on the availability of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than 2 previous major abdominal surgeries, or massive bowel distension were not treated laparoscopically. Peritonitis was not deemed a contraindication to laparoscopy.

RESULTS

The conversion rate was 5.8% and was mainly due to the presence of dense intraabdominal adhesions. Major complications ranged as high as 2.1% with a postoperative mortality of 0.6%. A definitive diagnosis was accomplished in 96.3% of cases, and 94.1% of these patients were treated successfully with laparoscopy.

CONCLUSIONS

Even if limited by its retrospective nature, the present experience shows that the laparoscopic approach to abdominal emergencies is as safe and effective as conventional surgery, has a higher diagnostic yield, and results in less trauma and a more rapid postoperative recovery. Such features make laparoscopy an attractive alternative to open surgery in the management algorithm for abdominal emergencies.

Laparoscopic appendectomy: why it should be done

OBJECTIVE

Notwithstanding its widely perceived advantages, laparoscopic appendectomy has not yet met with universal acceptance. The aim of the present work is to illustrate retrospectively the results of a case-control experience with laparoscopic versus open appendectomy carried out at our institution.

METHODS

Between January 1993 and November 2000, 555 patients (M:F = 210:345; mean age 25.2 +/- 15 years) underwent emergency or urgent appendectomy, or both. Of them, 322 (52%) were operated on laparoscopically, and 233 (48%) were treated via conventional surgery, according to the presence of a well-trained surgical team.

RESULTS

The laparoscopic group conversion rate was 3.1% (10/322) and was mainly due to the presence of dense intraabdominal adhesions. Major intraoperative complications ranged as high as 0.3% (1/322) and 0%, respectively, in the laparoscopic and conventional groups (P=ns). Major postoperative complications were 1.6% (5/312) vs 0.8% (2/243), respectively (P=ns). Postoperative mortality was 0.3% (1/312) and 0.4% (1/243) in the laparoscopic and conventional subsets of patients. Reinterventions were 0.9% (3/322) in the laparoscopic patients versus nil in the open group (P=ns). Minor postoperative complications were observed in 0.6% (2/312) and 6.5% (16/243) of patients, respectively, in the laparoscopy and open surgery groups, and consisted mainly of wound infections (P=0.001). Flatus passage and hospitalization were significantly more rapid among the laparoscopic patients. The greater diagnostic accuracy of laparoscopy allowed the diagnosis of concurrent diseases in 12% (30/254) versus 1.5% (3/199) of patients with histology proven appendicitis treated via laparoscopy versus laparotomy (P<0.01). Similarly, among those patients without gross or microscopic evidence of appendicitis, or both gross and microscopic evidence, concurrent diseases were detected in 57.3% (39/68) of laparoscopic patients versus 8.8% (3/34) in the conventional ones (P<0.01).

CONCLUSION

Even if limited by its retrospective nature, the present experience shows that laparoscopic appendectomy is as safe and effective as conventional surgery, has a higher diagnostic yield, causes less trauma, and offers a more rapid postoperative recovery. Such features make laparoscopy a challenging alternative to laparotomy in premenopausal women referred for urgent abdominal or pelvic surgery, or both.

The use of laparoscopy in abdominal emergencies

BACKGROUND

The purpose of this article is to describe our experience using laparoscopy in the management of emergent and acute abdominal conditions.

METHODS

Between March 1997 and November 2001, 277 consecutive minimally invasive procedures were performed for various nontrauma surgical emergencies. The indications for operation were nonspecific abdominal pain in 129 cases (46%), peritonitis in 64 cases (23%), small bowel obstruction in 52 cases (19%), complications after previous surgery or invasive procedures in 24 cases (9%), and sepsis of unknown origin in 8 cases (3%).

RESULTS

Laparoscopy obtained a correct diagnosis in 98.6% of the cases. In 207 patients (75%), the procedure was completed laparoscopically. An additional 35 patients (12.5%) required a target incision. The remaining 35 patients (12.5%) underwent formal laparotomy. The morbidity rate was 5.8%. No laparoscopy-related mortality was observed.

CONCLUSIONS

For patients with abdominal emergencies, the laparoscopic approach provides diagnostic accuracy and therapeutic options, avoids extensive preoperative studies, averts delays in operative intervention, and appears to reduce morbidity.
