ABSTRACT

Purpose@#Surgical management of obstructive left colon cancer (OLCC) is still a matter of debate. The classic Hartmann procedure (HP) has a disadvantage that requires a second major operation. Subtotal colectomy/total abdominal colectomy (STC/TC) with ileosigmoid or ileorectal anastomosis is proposed as an alternative procedure to avoid stoma and anastomotic leakage. However, doubts about morbidity and functional outcome and lack of long-term outcomes have made surgeons hesitate to perform this procedure. Therefore, this trial was designed to provide data for morbidity, functional outcomes, and long-term outcomes of STC/TC. @*Methods@#This study retrospectively analyzed consecutive cases of OLCC that were treated by STC/TC between January 2000 and November 2020 at a single tertiary referral center. Perioperative outcomes and long-term outcomes of STC/TC were analyzed. @*Results@#Twenty-five descending colon cancer (45.5%) and 30 sigmoid colon cancer cases (54.5%) were enrolled in this study. Postoperative complications occurred in 12 patients. The majority complication was postoperative ileus (10 of 12). Anastomotic leakage and perioperative mortality were not observed. At 6 to 12 weeks after the surgery, the median frequency of defecation was twice per day (interquartile range, 1–3 times per day). Eight patients (14.5%) required medication during this period, but only 3 of 8 patients required medication after 1 year. The 3-year disease-free survival was 72.7% and 3-year overall survival was 86.7%. @*Conclusion@#The risk of anastomotic leakage is low after STC/TC. Functional and long-term outcomes are also acceptable. Therefore, STC/TC for OLCC is a safe, 1-stage procedure that does not require diverting stoma.

ABSTRACT

Purpose@#Acute appendicitis is the most common nonobstetric indication for surgical intervention during pregnancy. In the argument of the optimal surgical approach to acute appendicitis in pregnancy, laparoscopy seems to be won with a similar complication rate and shorter postoperative recovery than open. We aimed to compare perioperative outcomes of appendectomy in pregnant and nonpregnant women in the totally laparoscopic age. @*Methods@#We retrospectively analyzed 556 nonincidental appendectomies performed in women (aged 18–45 years) between January 2014 and December 2018. To reduce the confounding effects, we used propensity score considering the variables age, American Society of Anesthesiologists physical status classification, and the operative finding; whether the appendicitis was simple or complicated. After propensity score matching, the outcomes of 15 pregnant women were compared with those of the 30 nonpregnant women. @*Results@#All the operations were performed with laparoscopy. Most of the pregnant cases were in their first and second trimester. The postoperative morbidity rate was significantly higher in the pregnant group before propensity score matching; however, the significance disappeared after matching. Operative outcomes and the parameters related to the postoperative recovery were not different between the two groups. Two patients in their first trimester decided to terminate the pregnancy after appendectomy. One patient in her second trimester experienced preterm labor which was resolved spontaneously. There was no other obstetric adverse outcome. @*Conclusion@#In the laparoscopy age, appendectomy during pregnancy is safe and not associated with a significantly increased risk of postoperative complication.

ABSTRACT

Purpose@#The purpose of this randomized controlled trial was to compare the effects of abdominal binder after laparoscopic cholecystectomy. @*Methods@#From August to December 2020, 66 patients who were set to undergo cholecystectomy were selected for a prospective trial at Kangbuk Samsung Hospital, Seoul, Republic of Korea, and their clinical characteristics and postoperative surgical outcomes were evaluated. Among 66 patients, 33 patients belong to the abdominal binder group and the other 33 patients belong to the control group. @*Results@#The average hospital stay was 2.46 ± 1.29 days, and was not significantly different between the two groups. The average postoperative pain score (visual analogue scale, 0–10) 12, 24, and 48 hours after surgery were not significantly different. However, the degree of comfort score was significantly higher for the control group patients (2.56 vs. 3.33, p < 0.001). Time to the first ambulation, walking ability, return of bowel function, time to full diet resumption, and the numbers of analgesics and antiemetics administered were not significantly different between the two groups. @*Conclusion@#No postoperative recovery benefit and no reduction in hospital stay was found in patients who used an abdominal binder while undergoing laparoscopic cholecystectomy. Statistically, between the group that used the binder and the one that did not, no significant differences in surgical outcome nor postoperative outcome were observed. The only exception was that the degree of comfort score was significantly higher in the control group. Therefore, in terms of patient benefit and convenience, wearing an abdominal binder after laparoscopic cholecystectomy is not recommended.

ABSTRACT

Purpose@#There are various opinions about the postoperative complications of the two methods for laparoscopic inguinal hernia surgery; totally extraperitoneal repair (TEP) and transabdominal preperitoneal repair (TAPP). The aim of this study was to compare the postoperative course after TAPP and TEP, focusing on immediate postoperative pain, incidence of postoperative urinary retention (POUR), and chronic pain. @*Methods@#This study retrospectively analyzed a consecutive series of 344 inguinal hernia patients who were treated with laparoscopic surgery between November 2016 and December 2019 at a single tertiary referral center. @*Results@#Patient demographics did not differ significantly between the groups. The operation time was significantly shorter in the TEP group than in the TAPP group (43.1 ± 14.9 minutes vs. 63.5 ± 16.5 minutes, p < 0.001). The postoperative pain scores were significantly lower in the TEP group than in the TAPP group immediately (3.6 ± 1.3 vs. 4.4 ± 1.1, p < 0.001) and 6 hours (1.5 ± 1.4 vs. 2.3 ± 1.8, p < 0.001) after the operation. The other complications did not differ significantly between the groups. Age was a significant risk factor for POUR (odds ratio [OR], 1.083; 95% confidence interval [CI], 1.018–1.151; p = 0.011), and history of benign prostate hyperplasia (BPH) was a significant risk factor for chronic pain (OR, 5.363; 95% CI, 1.028–27.962; p = 0.046). @*Conclusion@#TEP and TAPP seem to be safe and effective for laparoscopic inguinal hernia repair and have similar postoperative outcomes. Age was a significant risk factor for POUR, and BPH history was a significant risk factor for chronic pain.

ABSTRACT

Purpose@#We evaluated the impact of preoperative magnetic resonance cholangiopancreatography (MRCP) on patient outcomes, and found which patients should be considered for MRCP before cholecystectomy. @*Methods@#We performed retrospective analysis of 2,072 patients that underwent cholecystectomy for benign gallbladder disease from January 2014 to June 2017. Patients were grouped as CT only group (n = 737) and MRCP group (n = 1,335), including both CT and MRCP (n = 1,292) or MRCP only (n = 43). The main outcome measure was associated with complications after cholecystectomy, and the secondary outcomes were hospital stay, readmission, and events that could impact patient management due to addition of MRCP. @*Results@#There were no statistical differences in occurrence of intraoperative or postoperative complications or readmission rate between the 2 groups. Hospital stay was about 0.6 days longer in the MRCP group. However, MRCP group was more susceptible to complications due to underlying patient demographics (older age, higher frequency of diabetes, and higher level of the inflammatory markers). MRCP diagnosed common bile duct (CBD) stones in 6.5% of patients (84/1,292) without CBD stones in CT, and bile duct anomalies were identified in 41 patients (3.2%). Elevated γ-GT was the only independent factor for additional detection of CBD stones (adjusted odds ratio [OR], 2.89; P = 0.029) and subsequent biliary procedures (adjusted OR, 3.34; P = 0.018) when additional MRCP was performed. @*Conclusion@#MRCP is valuable for identification of bile duct variation and CBD stones. Preoperative MRCP can be considered, particularly in patients with elevated γ-GT, for proper preoperative management and avoidance of complications.

ABSTRACT

Purpose@#The low rate of recurrent appendicitis after initial nonsurgical management of complicated appendicitis supports the recently implemented strategy of omitting routine interval appendectomy. However, several reports have suggested an increased incidence rate of neoplasms in these patients. We aimed to identify the risk of neoplasms in the population undergoing interval appendectomy. @*Methods@#This study retrospectively analyzed consecutive cases of appendicitis that were treated surgically between January 2014 and December 2018 at a single tertiary referral center. Patients were divided into 2 groups depending on whether they underwent immediate or interval appendectomy. Demographics and perioperative clinical and pathologic parameters were analyzed. @*Results@#All 2,013 adults included in the study underwent surgical treatment because of an initial diagnosis of acute appendicitis. Of these, 5.5% (111 of 2,013) underwent interval appendectomy. Appendiceal neoplasm was identified on pathologic analysis in 36 cases (1.8%). The incidence of neoplasm in the interval group was 12.6% (14 of 111), which was significantly higher than that of the immediate group (1.2% [22 of 1,902], P < 0.001). Conclusion: The incidence rate of neoplasms was significantly higher in patients undergoing interval appendectomy.These findings should be considered when choosing treatment options after successful nonsurgical management of complicated appendicitis.

ABSTRACT

Purpose@#Choosing the appropriate antibiotic is important for treatment of complicated appendicitis. However, increasing multidrug resistant bacteria have been a serious problem for successful treatment. This study was designed to identify bacteria isolated from patients with complicated appendicitis and reveal their susceptibilities for antibiotics and their relationship with patient clinical course. @*Methods@#This study included patients diagnosed with complicated appendicitis and examined the bacterial cultures and antimicrobial susceptibilities of the isolates. Data were retrospectively collected from medical records of Kangbuk Samsung Hospital from January 2008 to February 2018. @*Results@#The common bacterial species cultured in complicated appendicitis were as follows: Escherichia coli (n=113, 48.9%), Streptococcus spp. (n=29, 12.6%), Pseudomonas spp. (n=23, 10.0%), Bacteriodes spp. (n=22, 9.5%), Klebsiella (n=11, 4.8%), and Enterococcus spp. (n=8, 3.5%). In antibiotics susceptibility testing, the positive rate of extended-spectrum beta lactamase (ESBL) was 9.1% (21 of 231). The resistance rate to carbapenem was 1.7% (4 of 231), while that to vancomycin was 0.4% (1 of 231). E. coli was 16.8% ESBL positive (19 of 113) and had 22.1% and 19.5% resistance rates to cefotaxime and ceftazidime, respectively. Inappropriate empirical antibiotic treatment (IEAT) occurred in 55 cases (31.8%) and was significantly related with organ/space surgical site infection (SSI) (7 of 55, P=0.005). @*Conclusion@#The rate of antibiotic resistance organisms was high in community-acquired complicated appendicitis in Koreans. Additionally, IEAT in complicated appendicitis may lead to increased rates of SSI. Routine intraoperative culture in patients with complicated appendicitis may be an effective strategy for appropriate antibiotic regimen.

ABSTRACT

Objective@#We aimed to evaluate the diagnostic value and prognostic relevance of FDG positron emission tomography/computed tomography (PET-CT) in extrahepatic cholangiocarcinoma patients. @*Materials and Methods@#This study included 234 extrahepatic cholangiocarcinoma patients who underwent FDG PET-CT between June 2008 and February 2016. The diagnostic performance of FDG PEG-CT was compared to that of contrast-enhanced multidetector row CT (MDCT) and MRI. Independent prognosticators for poor survival were also assessed. @*Results@#The sensitivity of FDG PET-CT for detecting primary tumor and regional lymph node metastases was lower than that of MDCT or MRI (p < 0.001), whereas the specificity and positive predictive value for detecting regional lymph nodes metastases was significantly better in FDG PET-CT compared to MDCT and MRI (all p < 0.001). There was no significant difference in the diagnostic yield of distant metastases detection among three diagnostic imaging techniques. In a multivariate analysis, maximum standardized uptake values (SUVmax) of the primary tumor (adjusted hazard ratio [HR], 1.75; 95% confidence interval [CI], 1.13–2.69) and of the metastatic lesions ≥ 5 (adjusted HR, 8.10; 95% CI, 1.96–33.5) were independent contributors to poor overall survival in extrahepatic cholangiocarcinoma patients. In a subgroup analysis of 187 patients with periductal infiltrating type of cholangiocarcinoma, an SUVmax of the primary tumor ≥ 5 was associated with an increased risk of regional lymph node (adjusted odds ratio [OR], 1.60; 95% CI, 0.55–4.63) and distant metastases (adjusted OR, 100.57; 95% CI, 3.94– 2567.43) at diagnosis as well as with poor overall survival (adjusted HR, 1.81; 95% CI, 1.04–3.15). @*Conclusion@#FDG PET-CT showed lower sensitivity for detecting primary tumor and regional lymph node involvement than MDCT and MRI. However, the SUVmax of primary tumors and metastatic lesions derived from FDG PET-CT could have significant implications for predicting prognoses in extrahepatic cholangiocarcinoma patients.

ABSTRACT

PURPOSE: Safe and effective surgical treatment of peptic ulcer perforations is fundamental to achieve favorable outcomes. We present laparoscopic single figure of eight suturing omentopexy for perforated duodenal ulcer and review associated clinical outcomes. This is a new formulaic surgical technique for laparoscopic omentopexy. METHODS: Laparoscopic single figure of eight suturing omentopexies for perforated duodenal ulcer were completed in 15 consecutive patients between April 2008 and November 2017 at Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Korea. Using prospectively collected data, we performed an observational study on an intention-to-treat basis. RESULTS: The mean age of the 15 patients who underwent laparoscopic repair was 41.7±13.9 years. The perforation site was the anterior duodenal bulb in all patients. The median perforation size was 5 mm (range: 3~8 mm). The mean operation time was 66.7±19.6 minutes. There was no evidence of leakage from the omentopexy site clinically or in the postoperative upper gastrointestinal series. One patient (6.7%) experienced the postoperative complication of pneumothorax. There were no cases of postoperative mortality or reoperation within 30 days after surgery. The median time to tolerance of regular diet was 6 (range: 4~9) days. The median postoperative hospital stay was 7 days (range: 5~11 days). CONCLUSION: Laparoscopic single figure of eight suturing omentopexy can be a viable option in the surgical management of perforated duodenal ulcer in selected patients without surgical risk factors. Laparoscopic single figure of eight suturing omentopexy is safe and easy to perform, and may therefore reduce operation time.

ABSTRACT

PURPOSE: According to surgical dogma, patients who are recovering from general anesthesia after abdominal surgery should begin with a clear liquid diet, progress to a full liquid diet and then to a soft diet before taking regular meals. We propose patient-controlled nutrition (PCN), which is a novel concept in postoperative nutrition after abdominal surgery. METHODS: A retrospective pilot study was conducted to evaluate the feasibility and effects of PCN. This study was carried out with a total of 179 consecutive patients who underwent a laparoscopic appendectomy between August 2014 and July 2016. In the PCN group, diet was advanced depending on the choice of the patients themselves; in the traditional group, diet was progressively advanced to a full liquid or soft diet and then a regular diet as tolerated. The primary endpoints were time to tolerance of regular diet and postoperative hospital stay. RESULTS: Time to tolerance of a regular diet (P < 0.001) and postoperative hospital stay (P < 0.001) showed statistically significant differences between the groups. Multivariate analysis using linear regression showed that the traditional nutrition pattern was the only factor associated with postoperative hospital stay (P < 0.001). Multivariate analysis using logistic regression showed that traditional nutrition was the only risk factor associated with prolonged postoperative hospital stay (≥3 days). CONCLUSION: After abdominal surgery, PCN may be a feasible and effective concept in postoperative nutrition. In our Early Recovery after Surgery program, our PCN concept may reduce the time to tolerance of a regular diet and shorten the postoperative hospital stay.

ABSTRACT

PURPOSE: Continued efforts to reduce the invasiveness of conventional cholecystectomy techniques have resulted in the development of single-incision cholecystectomy. However, a single-port approach has significant limitations associated with proper triangulation and instrument crowding and collisions. Although the da Vinci Single-Site robotic system has been proposed to overcome these problems, objective evidence of the feasibility and ergonomics of single-incision robotic cholecystectomy (SIRC) is insufficient. Therefore, the present study aimed to evaluate the feasibility and efficacy of SIRC by using objective data obtained from consecutive patients who underwent surgery with the single-incision robotic platform performed by a single surgeon. METHODS: Forty patients who underwent SIRC between August 2014 and December 2015 were identified. Demographic, perioperative, and postoperative data were collected retrospectively. RESULTS: The mean docking time was 10.82±4.85 min (range, 4~30 min). The mean console time was 49.63±10.82 min (range, 24~90 min). None of the patients required an additional laparoscopic arm, an additional robotic arm, or conversion to conventional laparoscopic cholecystectomy. CONCLUSION: SIRC can provide a safe operative procedure, good operative results, and high patient satisfaction, and cause less surgeon fatigue. Therefore, our study results indicate that SIRC is feasible and favorable for both patients and physicians.

ABSTRACT

PURPOSE: This study compared a subtotal colectomy to self-expandable metallic stent (SEMS) insertion as a bridge to surgery for patients with left colon-cancer obstruction. METHODS: Ninety-four consecutive patients with left colon-cancer obstruction underwent an emergency subtotal colectomy or elective SEMS insertion between January 2007 and August 2014. Using prospectively collected data, we performed a retrospective comparative analysis on an intention-to-treat basis. RESULTS: A subtotal colectomy and SEMS insertion were attempted in 24 and 70 patients, respectively. SEMS insertion technically failed in 5 patients (7.1%). The mean age and rate of obstruction in the descending colon were higher in the subtotal colectomy group than the SEMS group. Sex, underlying disease, American Society of Anesthesiologists physical status, and pathological stage showed no statistical difference. Laparoscopic surgery was performed more frequently in patients in the SEMS group (62 of 70, 88.6%) than in patients in the subtotal colectomy group (4 of 24, 16.7%). The overall rate of postoperative morbidity was higher in the SEMS group. No Clavien-Dindo grade III or IV complications occurred in the subtotal colectomy group, but 2 patients (2.9%) died from septic complications in the SEMS group. One patient (4.2%) in the subtotal colectomy group had synchronous cancer. The total hospital stay was shorter in the subtotal colectomy group. The median number of bowel movements in the subtotal colectomy group was twice per day at postoperative 3–6 months. CONCLUSION: A subtotal colectomy for patients with obstructive left-colon cancer is a clinically and oncologically safer, 1-stage, surgical strategy compared to SEMS insertion as a bridge to surgery.

ABSTRACT

PURPOSE: Laparoscopy-assisted gastrectomy (LAG) is considered an alternative treatment option for gastric cancer. LAG is safe, however the long-term oncologic efficacy and survival of patients including those with advanced gastric cancer have not been assessed. The aim of this study was to evaluate long-term outcomes and survival of patients with gastric cancer, including advanced cases, who underwent LAG performed by a single surgeon. METHODS: Between January 2006 and December 2010, 161 patients with gastric cancer underwent LAG performed by a single surgeon. Clinicopathological data were collected retrospectively along with data on survival and prognosis. Overall survival (OS) and disease-free survival (DFS) were estimated using the Kaplan-Meier method. RESULTS: A total of 161 patients diagnosed with gastric cancer underwent LAG. Postoperative morbidity occurred in 12 patients. The median OS was 67.0 months (range, 1.0~97.0 months), and the median DFS was 67.0 months (range, 1.0~97.0 months). T stage, N stage, TNM stage, lymphatic invasion, and venous invasion influenced overall survival and disease recurrence. The OS rates according to N stage were 96.8% for N0, 94.4% for N1, 45.5% for N2, and 42.9% for N3. CONCLUSION: The current study showed that LAG for gastric cancer, including advanced gastric cancer, is technically feasible with acceptable long-term oncologic outcomes.

ABSTRACT

PURPOSE: A balloon dissector is widely used to achieve the preperitoneal space in totally extraperitoneal (TEP) inguinal hernia repair. The aim of this study was to compare the operative results of TEP cases performed with (the balloon dissection group) or without (the plain dissection group) a balloon dissector. METHODS: A retrospective analysis was conducted with a consecutive series of inguinal hernia repairs performed by a single surgeon in OOO Hospital between April 2008 and April 2012. All 128 patients with full-length video recordings were included. The distribution of the operation method was altered during the study period, from dissection with a balloon dissector to without it. RESULTS: Of 128 cases, 57 belonged to the balloon dissection group and the other 71 belonged to the plain dissection group. The demographic features and clinical characteristics were similar in both groups. Mean operation time (57.7 vs. 45.6 min, p<0.001) and laparoscopic recording time (31.6 vs. 25.0 min, p=0.004) were significantly shorter in the plain dissection group without differences in the degree of bloodstaining and the frequency of peritoneal tearing. Postoperative complications did not differ between the two groups. CONCLUSION: Plain dissection may be a safe and feasible alternative method of achieving the preperitoneal space in TEP by an experienced surgeon.

ABSTRACT

PURPOSE: A laparoscopic appendectomy is now commonly performed. The push in recent years toward reducing the number of ports required to perform this surgery has led to the development of a single-port laparoscopic appendectomy (SPA). We compared postoperative pain after an SPA using a glove port with a percutaneous organ-holding device (group 1) with that of an SPA using a commercially-available multichannel single-port device (group 2). METHODS: Between March 2010 and July 2011, a retrospective study was conducted of a total of 77 patients who underwent an SPA by three surgeons at department of surgery, Kangbuk Samsung Medical Center. Thirty-eight patients received an SPA using a glove port with a percutaneous organ-holding device. The other 39 patients received an SPA using a commercially-available multichannel single port (Octo-Port or SILS Port). Operative details and postoperative outcomes were collected and evaluated. RESULTS: There were no differences in the mean operative times, times to pass gas, postoperative hospital stays, or cosmetic satisfaction scores between the two groups. The pain score in the first 24 hours after surgery was higher in group 2 than group 1 patients (P < 0.001). Furthermore, the trocar used in group 2 was more expensive than that used in group 1. CONCLUSION: An SPA using a glove port with a percutaneous organ-holding device was associated with a lower pain score during the first 24 hours after surgery because of the shorter fascia incision length and a cheaper cost than an SPA using a commercially-available multichannel single-port device.

ABSTRACT

PURPOSE: Acute appendicitis is one of the most common surgical emergencies worldwide. Laparoscopic appendectomy (LA) is being accepted as the 'gold standard' surgery for simple acute appendicitis over open appendectomy (OA); however, for complicated appendicitis, no consensus has been reached with regard to which produces better outcomes. METHODS: We analyzed the data of patients who were diagnosed as complicated appendicitis, older than 18 years old, and underwent LA or OA from January 2008 to December 2012. A total of 2,173 patients had acute appendicitis during this period and 461 (21.2%) of them had complicated appendicitis; 335 patients were finally enrolled and divided into LA (280), OA (49), and Converted to open Appendectomy (CA) groups (6), respectively. Age, sex, preoperative WBC, operating time, stapler usage, time to diet and discharge, total cost and complication among the three groups were analyzed. RESULTS: No significant differences were observed in sex, age, history of abdominal surgery, preoperative WBC, and total cost. Shorter operating time (62.3+/-30.0 vs 87.3+/-40.2, p=0.000), shorter time to diet (2.7+/-2.2 vs 3.7+/-1.6, p=0.001), shorter postoperative stay (4.8+/-2.6 vs 7.1+/-2.5, p=0.000), shorter duration of pain (3.4+/-1.7 vs 5.6+/-2.8, p=0.000), and less frequent usage of pain killer (68.2% vs 89.1%, p<.001) were observed in the laparoscopic group. Complication rate was significantly lower in the LA group (4.6% vs 18.4%, p=0.002). CONCLUSION: Results of this study provide clinical evidence that laparoscopic surgery is a feasible and safe surgical modality for complicated appendicitis. Conduct of more reliable, large scaled, randomized prospective study will be necessary in order to prove the superiority of laparoscopic surgery for complicated appendicitis.

ABSTRACT

PURPOSE: Conventional laparoscopic appendectomy is performed using three ports, and single-port appendectomy is an attractive alternative in order to improve cosmesis. The aim of this study was to compare pain after transumbilical single-port laparoscopic appendectomy (SA) with pain after conventional three-port laparoscopic appendectomy (TA). METHODS: From April to September 2011, 50 consecutive patients underwent laparoscopic appendectomy for simple appendicitis without gangrene or perforation. Patients who had undergone appendectomy with a drainage procedure were excluded. The type of surgery was chosen based on patient preference after written informed consent was obtained. The primary endpoint was postoperative pain evaluated by the visual analogue scale score and postoperative analgesic use. Operative time, recovery of bowel function, and length of hospital stay were secondary outcome measures. RESULTS: SA using a SILS port (Covidien) was performed in 17 patients. The other 33 patients underwent TA. Pain scores in the 24 hours after surgery were higher in patients who underwent SA (P = 0.009). The change in postoperative pain score over time was significantly different between the two groups (P = 0.021). SA patients received more total doses of analgesics (nonsteroidal anti-inflammatory drugs) in the 24 hours following surgery, but the difference was not statistically significant. The median operative time was longer for SA (P < 0.001). CONCLUSION: Laparoscopic surgeons should be concerned about longer operation times and higher immediate postoperative pain scores in patients who undergo SA.
