ABSTRACT
INTRODUCTION: Obstetric anal sphincter injuries (OASIS) may be underdetected in primiparous women. This study evaluated the prevalence of OASIS in primiparous women after normal vaginal delivery or instrumental delivery using endoanal ultrasound (US) during postnatal follow-up. METHODS: This study retrospectively analysed endoanal US data collected during postnatal follow-up (6-12 months after vaginal delivery) at a tertiary hospital in Hong Kong. Offline analysis to determine the prevalence of OASIS was performed by two researchers who were blinded to the clinical diagnosis. Symptoms of faecal and flatal incontinence were assessed with the Pelvic Floor Distress Inventory. RESULTS: Of 542 women included in the study, 205 had normal vaginal delivery and 337 had instrumental delivery. The prevalence of OASIS detected by endoanal US was 7.8% (95% confidence interval [CI]=4.1%-11.5%) in the normal vaginal delivery group and 5.6% (95% CI=3.1%-8.1%) in the instrumental delivery group. Overall, 82.9% of women with OASIS on endoanal US did not show clinical signs of OASIS. Birth weight was significantly higher in the OASIS group (P=0.012). At 6 to 12 months after delivery, 5.5% of women reported faecal incontinence and 17.9% reported flatal incontinence, but OASIS was not associated with these symptoms. CONCLUSIONS: Additional training for midwives and doctors may improve OASIS detection.

BACKGROUND: The aim of this study was to determine the predictive risk factors for complications resulting from foreign body ingestion. METHODS: A consecutive series of 1338 patients with suspected foreign body ingestion presenting from 1996 to 2000 were studied retrospectively. The potential risk factors for complications after foreign body ingestion were analysed by multivariate logistic regression and included concurrent medical illness, age, duration and types of symptoms, types of foreign body ingested, positive cervical radiographic findings and the level of foreign body impaction. RESULTS: Fish bone (62.7 per cent) was the commonest type of foreign body ingested. Most of the objects were impacted at or above the cricopharyngeus, the commonest site being the valleculae (31.4 per cent). Multivariate analysis showed that presentation delayed for more than 2 days (P < 0.001), positive cervical radiographic findings (P < 0.001) and foreign body impacted at the cricopharyngeus (P = 0.009) or upper oesophagus (P = 0.005) were significant independent risk factors associated with the development of complications after foreign body ingestion. CONCLUSION: In patients with a foreign body seen on plain cervical radiography, presentation delayed for more than 2 days after ingestion, and foreign body impacted at the level of the cricopharyngeus or oesophagus there is a high degree of correlation with the occurrence of complications. Awareness should be raised when these risk factors are present.

AIM: Recurrent bleeding after initial haemostasis is an important factor that directly relates to the outcome in the management of peptic ulcer bleeding. Conflicting reports have been published concerning the effectiveness of scheduled second therapeutic endoscopy on ulcer rebleeding. We investigate the use of scheduled second endoscopy with appropriate therapy on peptic ulcer rebleeding. METHODS: From August 1999 to January 2001, we prospectively randomised patients who had endoscopically confirmed bleeding peptic ulcer with stigmata of acute bleeding, visible vessel, or adherent clot into two groups. Endoscopic therapy was standardised to initial epinephrine injection and subsequent heater probe application. The study group (n = 100) received scheduled second endoscopy 16-24 hours after initial haemostasis, and further therapy was applied if endoscopic stigmata persisted, as above. The control group (n = 94) were observed closely. Those patients that developed rebleeding in either group underwent operation if further endoscopic therapy failed. Outcome measures included ulcer rebleeding, transfusion, duration of stay, and mortality. RESULTS: After initial endoscopic haemostasis, 194 eligible patients were randomised into two groups. Thirteen patients in the control group developed recurrent bleeding within 30 days while five patients in the study group sustained recurrent bleeding (p = 0.0314) (relative risks 0.33, 95% confidence interval 0.1-0.96). The number of patients that required surgery for recurrent bleeding was six in the control group and one in the study group (p = 0.05). There was no difference in duration of hospital stay, transfusion, or mortality between the two groups. CONCLUSIONS: A scheduled repeat endoscopy with appropriate therapy 16-24 hours after initial endoscopic haemostasis reduces the number of cases of recurrent bleeding.

Sialocele is an uncommon complication of parotidectomy. Most cases resolve after conservative therapy consisting of repeated aspiration and pressure dressing. The condition is, however, occasionally resistant to such therapy. We report on a 52-year-old Chinese man who had a 10-year history of right parotid swelling. Following fine-needle aspiration cytology, Warthin's tumour was diagnosed, but after elective parotidectomy, a swelling developed and parotid sialocele was diagnosed. Botulinum toxin type A was given after the sialocele had persisted for almost 3 weeks after surgery, and after conservative management had been tried; the sialocele disappeared after two doses of treatment. Botulinum toxin therapy was thus an effective method of treating persistent sialocele.

BACKGROUND: Transoral removal and sialoadenectomy are the two main modalities of treatment for submandibular stones. However, missed ductal stones are not uncommon, and there is a risk of lingual or hypoglossal nerve injury. We attempted to avoid these complications by using an endoscopic technique. METHODS: The case notes of the patients who had undergone endoscopic removal of submandibular stones were studied retrospectively. The procedure was performed under general anesthesia. The submandibular orifice was incised by carbon dioxide laser, and a 3.1-mm rigid scope was inserted under direct vision with normal saline irrigation after dilatation. The stones were either broken down by laser or removed with a Dormia basket or forceps. RESULTS: A total of 13 patients underwent the procedure. The duration of median follow-up was 15 months. In 11 patients, the stones were identified and removed. No stone was found in two patients (15.4%). There were no false negatives, since no stones were discovered subsequently in these two patients. One, two, three, and four stones were present inside the ducts in seven patients (54.6%), one patient (7.7%), two patients (15.4%), and one patient (7.7%), respectively. The symptoms subsided completely in 11 patients within 4 weeks after the procedure. Persistent swelling occurred in two patients. In one of them, no residual stone was revealed by CT scan. The other patient had a large calculus that was only partially fragmented by laser lithotripsy at the initial operation. No lingual nerve or hypoglossal nerve injury was detected in any patient. CONCLUSION: Sialoendoscopy is a safe and efficacious treatment for submandibular ductal stones. It reduces the incidence of missed stones, and nerve injury, as well as the need for sialoadenectomy.

Lymphoepithelioma-like carcinoma is a rare tumour in the oral cavity and is characterized histologically by non-keratinizing, undifferentiated squamous cell carcinoma with lymphocytic infiltration. Three consecutive cases of intraoral lymphoepithelioma-like carcinoma are reported. A review of the literature reveals a similar biological behaviour to that of nasopharyngeal lymphoepithelioma: a high incidence of cervical nodal spread and remarkable radiosensitivity. Chemotherapy should be considered when nodal or distant metastases are present. The association of the Epstein-Barr virus with this tumour remains unclear but our experience suggests a positive correlation in Chinese individuals.

BACKGROUND: Acute diverticulitis of the caecum and ascending colon is uncommon. Controversies abound as regards the optimal surgical treatment, ranging from appendectomy, diverticulectomy to right hemicolectomy. The aim of the present paper was to review treatment strategy followed by a critical appraisal. METHODS: The case notes of 30 patients with acute diverticulitis of the right colon who were treated at the United Christian Hospital, Hong Kong from 1992 to 1998 were systematically reviewed. The data were subjected to statistical analysis. RESULTS: The median age was 34 years, with a male:female ratio of 1:1.15. All patients presented with acute right lower abdominal pain and localized rebound tenderness. All were diagnosed preoperatively as having appendicitis. The mean duration of symptoms was 2 days (range: 1-6 days). Two treatment groups were identified. Group A (n = 16; 53%) received appendicectomy alone, while group B (n = 14; 47%) underwent diverticulectomy in addition to appendicectomy, including one patient with perforated diverticulitis. Overall, there was no procedure-related morbidity or mortality. Both groups received a similar duration of broad-spectrum antibiotics. All the patients were interviewed by phone after operation to detect any recurrence of symptoms, with a median follow-up interval of 34 months (range: 11-78 months). There was no recurrence of symptoms in group A, which received appendicectomy and antibiotics. The only difference was operative time. CONCLUSION: For non-perforated diverticulitis of the right colon, appendicectomy and intravenous antibiotics without diverticulectomy is the preferred treatment strategy.

INTRODUCTION: Haemorrhoidectomy is traditionally an inpatient procedure. With many benefits, the day-surgery arrangement is an attractive alternative. The feasibility of day-surgery haemorrhoidectomy was explored and the hospital days were calculated in a case controlled design. METHODS: A single surgeon's experience of day-surgery haemorrhoidectomy between 1 July 1999 and 31 March 2000 was compared with inpatient haemorrhoidectomy during the same period. The operations were performed at United Christian Hospital Department of Surgery, Hong Kong (a government-funded public hospital). Statistical tests were applied where appropriate. RESULTS: There were 30 day-surgery and 15 inpatient haemorrhoidectomies. The groups were comparable in terms of age, gender, severity of haemorrhoids, method and duration of haemorrhoidectomy, blood loss, residual haemorrhoids, duration of follow up and unplanned readmission rate. Significantly more day-patients received general than spinal anaesthesia. Twenty-six of 30 (87%) patients were successfully discharged after day surgery. Two were admitted for transient fever (< 24 h), one for micturition syncope and one for acute urinary retention. There were four unplanned readmissions after day surgery: one for pain and three for secondary bleeding. All stopped spontaneously. All three unplanned readmissions after inpatient surgery were for secondary bleeding. All stopped spontaneously. Patient stay was significantly shorter for day surgery (1 +/- 1 day) than for the inpatient arrangement (4 +/- 1.6 days). CONCLUSION: Day-surgery haemorrhoidectomy is feasible. The significantly shorter hospital stay implies savings in public medical expenses.

OBJECTIVE: To study the outcome and complications of thyroid surgery. DESIGN: Retrospective study. SETTING: Regional hospital, Hong Kong. PATIENTS: Three hundred and twelve patients (266 women and 46 men) underwent thyroid surgery between January 1994 and December 1999. MAIN OUTCOME MEASURES: Complications of thyroidectomy for various thyroid diseases according to surgical technique used. RESULTS: Capsular dissection gradually became a more popular surgical technique: 33% and 58% in the first and second halves of the study period respectively (P<0.001). The overall rate of permanent vocal cord palsy was 2%. Near-total thyroidectomy became the preferred surgical treatment for toxic goitre over the study period. The incidence of recurrent hyperthyroidism was reduced from 21% to 7% (P>0.1, not significant). The incidence of hypoparathyroidism was approximately 30% after thyroidectomy for cancer. CONCLUSION: Capsular dissection is increasingly utilised in thyroid surgery. Low complication rates can be achieved after thyroidectomy for benign diseases. Hypoparathyroidism, however, is a relatively common complication after surgery for thyroid cancer.

A facial depressed deformity subsequent to superficial parotidectomy is unsightly. Although a facelift incision can improve the cosmetic outcome by concealing the scar, the hollow contour around the angle of the mandible remains conspicuous. We have attempted to mitigate this problem by transposition of the sternomastoid muscle. Transposition of the sternomastoid muscle to cover the parotid bed after superficial parotidectomy for benign tumour was performed in eight consecutive patients. The histopathology and postoperative results, including complications and patient satisfaction, were analysed. The depressed deformity was considerably alleviated in all eight patients. All patients except one, who had a wound infection, were satisfied with the cosmetic outcome postoperatively. The extra operative time required for sternomastoid-muscle transposition was only 10 min. There was no morbidity related to this additional procedure. By combining this simple method with a facelift incision, an appealing cosmetic outcome can be achieved after superficial parotidectomy.

BACKGROUND AND PURPOSE: One advantage of minimal-access surgery is that it produces less pain. A radially expanding trocar has been claimed to reduce pain further. We aimed to evaluate this claim. PATIENTS AND METHODS: This was a randomized controlled single-blind clinical trial. Fifty-four patients who underwent laparoscopic cholecystectomy at the Department of Surgery, United Christian Hospital, Hong Kong, between July 1997 and September 1998 were randomized into either the study group or the control group. The radially expanding 10-mm trocar was used for the epigastric port in the study group. The conventional 10-mm metal trocar was used similarly in the control group. The operation was otherwise performed with a standardized technique. Another conventional 10-mm metal trocar was used for the subumbilical port for all patients. Pain was measured using a visual analog scale. Pain scores for the epigastric port and subumbilical port were documented for 3 days after the surgery. RESULTS: There was no difference in age, sex, diagnoses, operating time, or conversion rate. There was consistently no difference in the pain experienced in the subumbilical wound, whereas pain at the epigastric wound was consistently less with the radially expanding trocar (p < 0.05). CONCLUSION: The radially expanding trocar produces less early postoperative pain than the conventional metal trocar.

BACKGROUND: Laparoscopic-assisted resection for colorectal lesions is feasible, but most reported series are heterogeneous and noncomparative. The aim of this study was to investigate whether laparoscopic-assisted resection was better than open abdominoperineal resection for low rectal adenocarcinoma. METHODS: Twenty-five (study group) of 59 consecutive patients who were considered suitable were selected for laparoscopic-assisted abdominoperineal resection based on the availability of informed consent, laparoscopic instruments, and experienced surgeons. The results in these patients were compared with the other 34 patients operated on by the open method (control group). RESULTS: The median follow-up times for the study and control groups were 30.1 and 28.3 months, respectively. The operation time was significantly longer (t-test, p < 0.001), while operative blood loss (Mann-Whitney U test, p = 0.02), postoperative analgesic requirement (Mann-Whitney U test, p = 0.02), time to resume normal diet (Mann-Whitney U test, p = 0.04), and total hospital stay (Mann-Whitney U test, p = 0.02) were significantly less in the study than in the control group. The oncological clearance, complication rate, disease-free interval, and survival were comparable in the two groups. CONCLUSIONS: Laparoscopic-assisted abdominoperineal resection allowed earlier postoperative recovery, with equal oncological clearance, morbidity, mortality, disease-free interval, and survival.

BACKGROUND: With the advent of fine-needle aspiration cytology (FNAC), the role of frozen section (FS) in the management of non-toxic thyroid nodules has become uncertain. METHODS: During the period from January 1993 to December 1995, a total of 84 patients have undergone operative treatment for non-toxic thyroid nodules at the United Christian Hospital, Kowloon. The medical records of these patients were studied retrospectively. RESULTS: In the benign group, the diagnostic accuracy of FNAC was 94% and that of FS was 91%. If FNAC reported malignancy, the diagnostic accuracy was 70%. If FS reported malignancy, the report was accurate in 100%. Among the 43 cases reported as benign on FNAC, FS did not alter the surgical management in any case. In 10 cases reported as suspicious on FNAC, FS altered the surgical treatment in one (10%). However, among the 10 cases reported as malignant on FNAC, FS subsequently altered the surgical management in five cases (50%). In three cases of malignancy on FNAC, both FS and the final histopathology report showed benign disease. Hence, FS avoided overtreatment in three patients. CONCLUSION: Frozen section is indicated if pre-operative FNAC of the thyroid nodules suggests malignancy, in order to determine the extent of the operation and to avoid overtreatment of benign disease. However, FS can be omitted if FNAC is reported as benign or suspicious.

PURPOSE: Our aim was to test the hypothesis that laparoscopic-assisted resection for colorectal cancer has an immunologic advantage over traditional open surgery. METHODS: Sixteen patients with colorectal cancer were randomized to undergo laparoscopic-assisted resection or open surgery. Basic patient data were recorded, and serum interleukin-6 levels, relative proportions of lymphocytes, and human leukocyte antigen-DR expression on monocytes were determined at specific time intervals. RESULTS: Operating time was longer for laparoscopic-assisted resection (P=0.02), but analgesic requirements were less (P=0.04). All patients exhibited the following: interleukin-6 levels increased to a maximum at 4 hours and returned to preoperative levels within 48 hours. This response appeared greater for open resection (mean peak level, 313 vs. 173 pg/ml; P=0.25). Relative granulocytosis (P < 0.001) was seen within 48 hours, which was offset by a decrease in percentage of lymphocytes (P < 0.001). Changes in lymphocyte subfractions were most significant seven days postsurgery: natural killer cells decreased (P=0.003); T cells increased (P=0.008), with elevation in the CD4/CD8 ratio (P=0.003). B cells were largely unchanged at all time periods. Human leukocyte antigen-DR expression on monocytes was significantly less at 48 hours postsurgery (P < 0.001). All changes were reversed within three weeks of surgery. There were no differences when comparing laparoscopic-assisted resection with open surgery. CONCLUSIONS: Both laparoscopic-assisted resection and open surgery affect the immune response. It would appear that laparoscopic-assisted resection does not have an immunologic advantage over open surgery in patients with colorectal cancer.

BACKGROUND: The aim of this prospective randomized study was to define the optimum management between early and delayed laparoscopic cholecystectomy for patients with acute cholecystitis. METHODS: Patients were randomized to receive either early laparoscopic cholecystectomy within 24 h of randomization or initial conservative treatment followed by delayed laparoscopic cholecystectomy 6-8 weeks later. RESULTS: There were 53 patients in the early group and 51 in the delayed group. There was no significant difference in conversion rate (early 21 per cent versus delayed 24 per cent), postoperative analgesic requirement (1 versus 2 doses) and postoperative complications. However, the early group had significantly longer operating time (122.8 versus 106.6 min, P = 0.04) and shorter total hospital stay (7.6 versus 11.6 days, P < 0.001). CONCLUSION: Early laparoscopic cholecystectomy is safe and feasible for acute cholecystitis with the additional benefit of shorter total hospital stay. Apart from a shorter operating time, treating patients with delayed laparoscopic cholecystectomy does not offer additional benefit.

BACKGROUND: It is important to establish the precise location of a colorectal lesion preoperatively. We used a model based on colorectal cancer to assess the efficacy of colonoscopy in locating these lesions. METHODS: We retrospectively analyzed all consecutive new colorectal cancer cases at the Department of Surgery, United Christian Hospital, Hong Kong, in 1995. RESULTS: Of the 123 cases reviewed by us, 84 cases satisfied the analysis criteria. The overall accuracy was 81%. It was especially high in the rectosigmoid region (93%) and descending colon (100%). The overall predictive power was 83%. It was especially high in the right-sided colon (100%) and the rectosigmoid region (93%). CONCLUSIONS: We conclude that colonoscopy is an accurate means for locating lesions in the upper rectum and sigmoid colon. It is also very predictive of lesions in the upper rectum, sigmoid colon, and right-sided colon.

Percutaneous drainage is now the preferred initial treatment of subphrenic abscess. The result is best for simple, unilocular abscesses but less so for complex ones. Failure of drainage can lead to high morbidity and mortality. We describe a case in which a large multiloculated subphrenic abscess was successfully drained laparoscopically without contaminating the general peritoneal cavity.
