Caecal volvulus has been reported to be associated with various abdominal and pelvic pathologies.
Its signs and symptoms are usually non-specific and maybe overlooked in favour of benign causes,
such as constipation. A high degree of suspicion is required for prompt diagnosis. Herein, we
report on an unusual case of caecal volvulus after a dental procedure that was managed initially as
constipation.

Objective: the aim of this study was to determine the
usefulness of Rockall score in predicting outcomes of 30
days rebleeding, mortality and need for surgical intervention
of bleeding gastric and duodenal ulcers.
Methods: this is a retrospective cohort study of all the
emergency endoscopies performed in Hospital sultan Ismail
from January 2009 to October 2014 for indications of upper
gastrointestinal bleeding (UGIb). Data was extracted from
hospital's electronic database and only non-variceal bleeds
were included. Rockall score was calculated and outcomes
of 30 days rebleeding, mortality and need for surgery was
recorded. For each outcome, calibration was done using the
Goodness-of-fit tests and discriminative ability was
reflected by area under the receiver operating characteristic
curve (AUROc).
Results: A total of 1323 patients were included with a male
preponderance of 64%. the overall rates of rebleeding were
11.2%, mortality rate of 8.7% and need for surgery was 2%.
Low AUROc values for rebleeding (0.63), mortality (0.58) and
surgery (0.67) showed poor discriminative ability of Rockall
score. the Goodness-of-fit test also revealed that the
scoring system was poorly calibrated in outcomes of
rebleeding (p <0.001), mortality (p = 0.001) and surgery (p =
0.038) with p-value <0.05. Patients with high risk (scores ≥8)
displayed highest rebleeding and mortality rates of 20%
respectively in comparison to the moderate (score 3-7) and
low (score ≤2) risk groups.
conclusion: Rockall score has a poor discriminative ability
and is poorly calibrated for rebleeding, mortality and need
for surgery in upper gastrointestinal bleeding. However, it is
the best tool we have now to stratify patients into risk
groups.

The literature on adrenal gland tumour in HIV-infected
patients is scarce. We report a 46-year-old Malay man with
HIV and Hepatitis C infection presenting with a large nonfunctioning
adrenal tumour. Computed tomography showed
a large right adrenal tumour with heterogeneous
enhancement and central necrosis. A high index of
suspicion of a malignant tumour or pheochromocytoma led
us to surgical removal of the adrenal gland. In this case
report, we highlight important features to look for during
pre-op evaluation of a large adrenal mass. Appropriate
action should be taken when there is a suspicion of a
pheochromocytoma or malignancy.

An Intrauterine contraceptive devices (IUCD) is commonly inserted by the primary health care
physician. It can migrate into pelvic or abdominal organs. When a pregnancy occurs following an
insertion of an IUCD, there should be a high suspicion of uterine perforation or possible migration.
A radiograph can be done in the primary health care clinic to search for a missing IUCD. Early
referral to the urology service is warranted when a patient presents with recurrent urinary tract
infections. Removal of an intravesical IUCD can be managed with cystoscopy, laparoscopy or open
surgery. Herein, we report a case of IUCD migration into the bladder. This case will highlight the
importance of proper technique, careful insertion and the role of ultrasound.
5.Wilms tumour with poor response to pre-operative chemotherapy: A report of 2 cases
The Malaysian Journal of Pathology 2020;42(2):267-271
Majority of Wilms tumour (WT) responds well to pre-operative chemotherapy. In
Malaysia, incidence of WT is rare with only two cases reported per one million populations yearly.
This case report is to highlight on the awareness of WT in an Asian population and highlight two
cases and challenges faced after pre-operative chemotherapy. Case Report: In this case series, we
report on two cases of WT which had poor response to pre-operative chemotherapy. Both cases
underwent surgery after pre-operative chemotherapy and recovery was uneventful during a two-year
follow-up. Discussion: Both patients had chemotherapy prior planned surgery, but had unfortunate
poor tumour response. The tumour progressed in size which required a radical nephrectomy. The
histology report for the first case had more than 60% blastemal cells remaining despite giving
pre-operative chemotherapy with no focal anaplasia. This showed poor response to chemotherapy
evidenced by the high number of blastemal cells. The second case was a stromal type WT which
is known for poor response and may lead to enhancement of growth and maturation induced by
chemotherapy. These were the possible reason of poor response of WT in these two cases.

suspicion is needed for immediate diagnosis and prompttreatment. In this case series, two rare cases oftracheobronchial injuries is described showing variableclinical presentations with different levels of injury. Our firstcase was seen in a 20 years old male whom had a directimpact on the neck and presented with upper tracheal injury.On arrival, this patient was in respiratory distress and hadbilateral pneumothorax. Bilateral chest tube was insertedwith subsequent neck exploration. During the neckexploration, anastomosis of the injured trachea wasperformed. The second case was represented by a 35 yearsold man with right main bronchial injury. Upon initialpresentation, this patient appeared well and wascomfortable under room air. However he graduallydeteriorated one week after the trauma requiring surgicalintervention. Eventually a thoracotomy with primaryanastomosis of the bronchial tear was performed. Details ofboth cases including clinical presentation, imaging andprocedures done will be discussed in this article.

Percutaneous nephrostomy is relatively safe for temporary urinary diversion. However, colonic perforation due to percutaneous nephrostomy can happen with an incidence of 0.2% as reported in the English literatures. To our knowledge, this is the first case being reported as a complication following treatment for traumatic renal injury. This paper is to share our treatment approach which differs from the usual approach according to existing literatures. We report on a young man who sustained grade IV renal injury due to blunt trauma and was managed conservatively. The treatment of traumatic renal injury via urinary diversion was complicated with an iatrogenic colonic perforation. The management and subsequent treatment of this patient is discussed in this case report.

Purpose:
The purpose of this study was to demonstrate the feasibility and safety of laparoscopic-assisted anterior resection (LAAR) for colorectal cancer in a local Asian population.
Methods:
This is a retrospective review of all patients with colorectal cancer operated from November 2017 to October 2018. Main variables of interest were demography, type and surgery, length of stay (LOS), and the involvement of proximal and distal doughnut. Postoperative complications were analysed using chi-square or Fisher exact and Mann-Whitney tests.
Results:
There were 23 patients with a mean age of 62.5 ± 12.2 years. The mean time from diagnosis to surgery was 97.1 ± 154.84 days. There were 12 patients in the LAAR group and 11 in the open anterior resection (OAR) group. Duration of surgery was shorter in OAR (129.58 ± 51.38 minutes) compared to LAAR (147.91 ± 39.37 minutes). Mean LOS was shorter in the LAAR group with 5±1.5 days compared to the OAR group of 7.42 ± 4.25 days. However, there was no significant P-value for both duration of surgery (P = 0.322) or LOS (P = 0.87). A total of 3 complications were recorded after OAR and 2 after LAAR. Both groups had clear proximal and distal margins with 16 (12–18.5) harvested lymph nodes in LAAR and 18 (16–22) in OAR, which were equal (P = 0.155).
Conclusion
This study reports a shorter LOS in the minimally invasive group of 2 days with similar oncologic resection outcomes. This shows that LAAR is feasible in Malaysia and has potential outcome benefits.

Retained rectal foreign body, with its associated social stigma, is a medical condition that is infrequently reported in Malaysia. We report the surgical management of five cases of retained foreign objects in the rectum seen over a one-year period. There were three young and two elderly male patients. One of the elderly patients presented with altered bowel habits and an abdominal mass that mimicked a symptomatic colonic tumor. All patients had an abdominal radiograph which clinched the diagnosis of a retained foreign rectal body. Successfully retrieved objects included two bottles, one bidet device, and two sex toys. Open surgery for retrieval of the impacted rectal foreign body was required in one patient. All underwent successful retrievals without any adverse postoperative complications. In our case series, retained rectal foreign bodies were observed only in the male gender. The age presentation was bimodal, with age groups in the twenties and sixties. The treatment options used for the retrieval of these impacted foreign bodies included transanal extraction or explorative laparotomy. Proximal migration and delayed presentation are possible indications for the latter approach.

The incidence of neurenteric cyst (NC) is rare amongst spine tumors. It is most often asymptomatic but may present with sensory and motor symptoms. When associated with thoracic vertebra fusion it is not reported before, this complicates the placement of pedicle screw during posterior instrumentation. Herein, we report a case of thoracic spinal neurenteric cyst in a 40-year-old man that presents with chronic back pain, left lower limb weakness and numbness. Elective excision of NC over T6-T7 with laminectomy and multilevel posterior instrumentation was successfully performed with significant improvement of the symptoms. Neurenteric cyst is a rare spinal cord lesion which may cause permanent neurological sequalae. Complete surgical excision with spine fixation in this case provides good long-term outcome.
