Morbidity of colostomy reversal.

OBJECTIVE: To determine morbidity after colostomy reversal at a tertiary care hospital. METHODS: The retrospective case series was conducted at the Aga Khan University Hospital, Karachi, and comprised records of patients aged 15 years or more who underwent colostomy reversal from January 2003 to December 2011. Data was collected regarding demographics, procedure dates, indication, as well as type and location of colostomy. Details of colostomy reversal, including pre-operative, intra-operative and post-operative variables were recorded. RESULTS: The mean age of the 96 patients was 40±16 years; 72(75%) of them being males. The most frequent indications for fashioning of colostomy were bowel perforation in 53 (55.2%) and malignancy in 9(9.3%) patients. Intra-operative complications occurred in 5(5.2%) with bowel perforation in 3(3.1%) and bleeding in 2(2%) patients. Overall, 40(41.6%) patients had post-operative local complications; the most common being wound infection in 19(19.8%) followed by incisional hernia 15(15.6%). Patients who experienced post-operative complications had significantly longer hospital stay compared to those without complications (9±2.8 vs. 7±2.4days; p=0.038). CONCLUSIONS: Colostomy reversal was associated with non-negligible morbidity. The most common complications were wound infection and incisional hernia.

Inter-facility transfer of surgical emergencies in a developing country: effects on management and surgical outcomes.

OBJECTIVES: Outcomes of surgical emergencies are associated with promptness of the appropriate surgical intervention. However, delayed presentation of surgical patients is common in most developing countries. Delays commonly occur due to transfer of patients between facilities. The aim of the present study was to assess the effect of delays in treatment caused by inter-facility transfers of patients presenting with surgical emergencies as measured by objective and subjective parameters. METHODS: We prospectively collected data on all patients presenting with an acute surgical emergency at Aga Khan University Hospital (AKUH). Information regarding demographics, social class, reason and number of transfers, and distance traveled were collected. Patients were categorized into two groups, those transferred to AKUH from another facility (transferred) and direct arrivals (non-transfers). Differences between presenting physiological parameters, vital statistics, and management were tested between the two groups by the chi square and t tests. RESULTS: Ninety-nine patients were included, 49 (49.5 %) patients having been transferred from another facility. The most common reason for transfer was "lack of satisfactory surgical care." There were significant differences in presenting pulse, oxygen saturation, respiratory rate, fluid for resuscitation, glasgow coma scale, and revised trauma score (all p values <0.001) between transferred and non-transferred patients. In 56 patients there was a further delay in admission, and the most common reason was bed availability, followed by financial constraints. Three patients were shifted out of the hospital due to lack of ventilator, and 14 patients left against medical advice due to financial limitations. One patient died. CONCLUSIONS: Inter-facility transfer of patients with surgical emergencies is common. These patients arrive with deranged physiology which requires complex and prolonged hospital care. Patients who cannot afford treatment are most vulnerable to transfers and delays.

Rectal carcinoma under 40 years of age: seven-year post-treatment follow-up at a tertiary care hospital in Pakistan.

OBJECTIVES: To determine epidemiological characteristics, clinical presentation, histopathological features, and long-term follow-up of patients below 40 years of age with carcinoma rectum. METHODS: The retrospective case series comprised all patients presenting with histopathological diagnosis of carcinoma rectum with age 15-40 years at the Aga Khan University Hospital between January 1994 and December 2004. Details regarding patient demographics, pre-operative assessment, management and tumour grade and stage were obtained from a prospectively maintained database. Continuous and categorical variables in the data were analysed. RESULTS: Of the 23 patients in the study, 14 (60.89%) were male and 9 (39.13%) were female. Mean age of the subjects was 31+/- 5 years. Overall, 22 (95.6%) patients presented with rectal bleeding and 12 (52%) had altered bowel habit. The most common site for the tumour was lower rectum (n=20; 87%) and 13 (56.5%) required abdominoperineal resection. Local recurrence rate was 13% (n=3) and distant metastasis occurred in 2 (8.6%) patients during the seven year follow-up. Two (8.6%) patients died, and both had distant metastasis. CONCLUSION: Carcinoma rectum is uncommon but an important malignancy in patients aged below 40 years. The clinician should have a high index of suspicion in young patients presenting with bleeding per rectum, altered bowel habit and weight-loss.

CONGENITAL SCAPHOID MEGALOURETHRA: REVISITING A RARE ANOMALY.

Megalourethra is an infrequent malformation of the anterior urethra that is caused by the lack of corpus sponigosum and in severe cases is accompanied by the lack of corpora cavernosa as well. We report a five-year-old boy presented to us with scaphoid variety of megalourethra having complaints of ballooning of urethra during voiding. He was investigated with urethrogram and cystoscopy and subsequently repaired with Nesbitt Longitudinal Reduction Urethroplasty. He had smooth recovery postoperatively with normal voiding stream on follow up.

Isolated tuberculosis of tunica albuginea and tunica vaginalis presenting as acute hydrocoele: a diagnostic dilemma.

We report the first case of genital tuberculosis (TB) occurring in tunica albuginea (TA) and tunica vaginalis (TV) presenting as acute hydrocoele. A 35-year-old man presented with acute onset left scrotal swelling. Physical examination revealed left hemiscrotal swelling with overlying skin erythema and tenderness. Surgical exploration was carried out due to increasing pain and per operatively found thickened TA and TV with a single small nodule on TA. Histopathology revealed typical granuloma formation, however, no Mycobacterium was seen. Subsequent Ziehl-Neelsen stain on separate tissue specimen confirmed the presence of acid-fast bacilli. Based on these findings, antituberculous treatment was started involving daily isoniazid (INH), rifampicin, ethambutol and pyrazinamide for 2 months and further INH and rifampicin for further 4 months.

Diclofenac Suppository as a Preemptive Analgesia in Ultrasound-guided Biopsy of Prostate: Randomized Controlled Trial.

OBJECTIVE: To compare preprocedure Diclofenac suppository and Xylocaine gel with Xylocaine gel only in patients undergoing transrectal ultrasound (TRUS)-guided biopsy of prostate for pain. MATERIALS AND METHODS: It is a randomized controlled trial conducted on patients undergoing TRUS-guided biopsy for clinical or biochemical suspicion of prostate cancer following a written informed consent and Ethics Review Committee approval. Patients were randomized into 2 groups. Group A included those patients who received Diclofenac suppository 2 hours before in combination with 10 mL of 2% Xylocaine gel 5 minutes before biopsy. Group B received Xylocaine gel only. A visual analog scale was used to measure the pain scores at the time of TRUS probe insertion, just after taking biopsy cores and 2 hours after biopsy. RESULTS: A total of 100 patients were recruited in the study with 50 patients each in group A and B. Mean age of group A was 69.1 ± 10 years and 67.3 ± 8.1 years for group B. The mean pain score for group A and B at the time of probe insertion was 0.08 ± 0.27 and 0.34 ± 0.63 (P = .032), immediately after taking biopsy cores was 1.46 ± 1.15 and 4.68 ± 0.77 (P = .000), and 2 hours after biopsy was 0.14 ± 0.45 vs 2.40 ± 0.81 (P = .000), respectively. CONCLUSION: The mean pain score at the time of TRUS probe insertion, immediately after taking biopsy cores, and 2 hours after biopsy is statistically significantly higher in group B.

Optimal Management of Lower Polar Calyceal Stone 15 to 20 mm.

PURPOSE: To compare the stone clearance rate, efficiency quotient (EQ), and early complications of shock wave lithotripsy (SWL) and percutaneous nephrolithotomy (PCNL) for solitary lower-pole renal stones measuring 15 to 20 mm. MATERIALS AND METHODS: This was a retrospective matched-pair analysis of 142 patients (78 in the SWL and 64 in the PCNL group). Preoperative imaging was done by use of noncontrast computed tomography (CT kidney, ureter, and bladder [KUB]), intravenous urogram, or plain X-ray and ultrasound KUB to assess the largest dimension of the stones. Only patients with radiopaque stones were included. The stone-free rates were assessed with plain X-ray and ultrasound at 4 weeks. Data were analyzed by use of SPSS ver. 19. RESULTS: The patients' demographic profiles (age, body mass index) and the stone sizes were comparable in the two groups. The mean stone size was 17.4±2.12 in the PCNL group compared with 17.67±2.04 in the SWL group (p=0.45). At 4 weeks, 83% of patients undergoing PCNL were stone-free compared with 51% in the SWL group (p<0.001). The EQ for the PCNL group was 76% compared with 44% for the SWL group (p<0.001). Ancillary procedures were required by 9% of patients in the PCNL group compared with 15% in the SWL group. The complication rate was 19% in both groups. The SWL complications were minor. CONCLUSIONS: Stone clearance from the lower pole of solitary stones sized 15 to 20 mm at the greatest diameter following SWL is poorer. These calculi can be better managed with percutaneous surgery owing to its higher efficacy and acceptably low morbidity.

Conservative management of an abdominal gunshot injury with a peritoneal breach: wisdom or absurdity?

Surgical exploration has been the standard of care for abdominal gunshot injuries. The authors report a case of a 28-year-old man who sustained a transabdominal gunshot injury, which entered the anterior abdominal wall and exited adjacent to the T12 vertebra posteriorly with a tangential trajectory. On presentation, the patient was haemodynamically stable with no peritoneal signs. Based on trajectory of the bullet, intra-abdominal injury was suspected. Therefore a CT scan abdomen with intravenous and rectal contrast was performed. The CT scan revealed no extravasation of the rectal contrast but showed free air specks behind the descending colon. Delayed renal images of the left ureter were also normal. Based on the clinical findings, the patient was managed non-operatively with nothing per oral, intravenous antibiotics and frequent abdominal assessments. He made an uneventful recovery without necessitating laparotomy.
