Acute sigmoid volvulus: Results of surgical treatment in the teaching hospitals of Bamako

Colonic Volvulus: An Experience at Tertiary Care Hospital in Nepal

Introduction: Colonic volvulus is not an uncommon cause of large bowel obstruction. Limited research has been done about colonic volvulus in our part of the world which has been regarded as "volvulus belt." The aim of this study is to evaluate the clinical features, management, and factors affecting perioperative outcomes in patients with colonic volvulus.

Methods: A retrospective review of medical records of all patients managed for colonic volvulus in Universal College of Medical Sciences, Bhairahawa from January 2012 to December 2016 was done. Data on patient demographics, clinical course, methods of treatment, and outcomes were analyzed.

Results: A total of 62 patients (46 males) were studied. Mean age was 57.9 ± 10.4 years. The most common site involved was sigmoid (85.5%). The diagnosis was made by abdominal x-rays in 39 patients (62.2%), CT scan in 13 patients (21%), and laparotomy in 10 patients (16.1%). Fifty-eight patients (93.5%) were treated surgically. Resection and ostomy was the commonest operation performed in 30 patients (48.7%) followed by resection with anastomosis in 24 patients (38.7%). The overall complication was 38.7%. There were 9.7% of deaths. In multivariate analysis, age ( ≥ 60 years) (odds ratio (OR); 27.0, confidence interval (CI); (1.92-403), P; 0.01), preoperative hypotension (systolic blood pressure <90 mmHg) (OR; 7.82, CI; (1.19-51.2), P; 0.03), and gangrenous bowel (OR; 76.7, CI (3.60-1632), P; 0.005) were significant predictors of postoperative complications .

Conclusions: Volvulus of the colon is common in males and constipation is being commonest risk factors for volvulus. Surgeons should have a high index of suspicion and should be aware of these problems to make the early diagnosis with prompt treatment and to ensure better patient outcomes in volvulus endemic areas like ours.

Pattern of Lower Intestinal Ostomies in a Low-Income Country: Case of Southeast of Niger Republic

BACKGROUND

Intestinal ostomies are common surgical procedures performed in visceral surgery as part of management for several gastrointestinal diseases. This study aims to report the socio-demographic characteristics, indications and prognosis of intestinal ostomies in low-income country.

METHODS

This was a 4-year retrospective study (January 2013 to December 2016) at Zinder National Hospital (Niger). All patients with a digestive ostomy on an ileum or colic segment were included in the study.

RESULTS

During the study period, 2437 patients underwent digestive surgery, including 328 gastrointestinal stomas (13.5%). Patients classified ASA3 were 60.7% (n = 199). The median age was 12 years (IQ: 7-25). Children represent 64% (n = 210) of patients with ostomy. The sex ratio was 2.60. The stoma was performed in emergency in 96.3% (n = 316) of cases. Acute peritonitis was the main indication of the stoma in 70.73% (n = 232). The ileostomies accounted for 75.61% (n = 248). Ostomy was intended as temporary in 97.3% of cases (n = 319). Complications were observed in 188 patients (57.3%). Mortality was 14.02% (n = 46). The indigent status (OR: 4.15 [2.20-7.83], P = 000), ASA score 4 (OR: 2.53 [1.54-4.15], P = 0.0003), Altemeier class IV (OR: 4.03 [2.10-7.73], P = 0.0000) and ileostomy (OR: 2.7853 [1.47-5.29], P = 0.0018) were statistically associated with the occurrence of major complications. The mean time for stoma closure was 59.3 ± 14.5 days.

CONCLUSION

Acute peritonitis was the main indication of digestive ostomy. The occurrence of major complications was associated with bad socioeconomic status, ASA4 score, Altemeier class IV and ileostomy.
